Flux de lucru complet pe 8 stații: Imprimarea unui pahar de plastic fără margini
📌 Note: This section follows a structured How‑To format, making it ideal for HowTo Schema markup. Each step is a sequential action that users can follow to understand the complete printing process on the JST-R300-ACSM.
Station 1: Cup Feeding — Automatic Loading
Automatic feeding station for plastic cups on fully automatic screen printing machine
Operațiune: A mechanical gripper picks up the blank cup and places it onto the fixture on the 8‑station turntable.
Scop / Principiu: This feeding method is especially suitable for rimless plastic cups. The gripper securely holds the cup body without damaging the rim, ensuring consistent positioning for the subsequent printing process.
Puncte cheie de reținut: Pentru plastic cups with a rim, we offer a different solution that achieves higher speeds — up to 4,000 cups per hour. However, for pahare de plastic fără margini — which are commonly used for pahare pentru smoothie, pahare pentru ceai cu fructeși pahare de călătorie — this gripper‑based feeding system provides the best balance of speed and precision.
Station 2: Corona Treatment — Surface Preparation
Corona treatment station for PP plastic cup on fully automatic screen printing machine
Operațiune: The cup passes through the corona treatment station, where high‑frequency electrical discharge modifies the surface energy of the plastic.
Scop / Principiu: Pentru pahare de plastic — especially PP cups — the surface energy is naturally low, which causes poor ink adhesion. Corona treatment raises the surface energy, allowing the ink to bond firmly to the cup surface.
Puncte cheie de reținut: This step is essential for PP and PE plastic cups. If you are printing on paper cups or paper bowls, this process can be skipped entirely.
Station 3: Product Detection — Preventing Blank Printing
Operațiune: A sensor checks whether a cup is present on the fixture at Station 3.
Scop / Principiu: If the sensor detects no cup on the fixture, the machine stops automatically and triggers an alarm. This prevents the printing station from applying ink onto an empty fixture — avoiding ink contamination and potential machine damage.
Puncte cheie de reținut: This safety feature protects both the machine and the operator. Without this detection, ink would be printed directly onto the metal fixture, requiring time‑consuming cleanup and potentially affecting future print quality.
Station 4: Printing Station — The Core Action
Printing station with servo-driven screen movement on plastic cup screen printing machine
Operațiune: The screen moves left‑to‑right via a servo‑driven lead screw, while the cup fixture rotates synchronously. The squeegee presses down, forcing ink through the mesh onto the cup surface.(The standard model requires manual adjustment of the printing stroke and is not driven by a servo motor.）
Scop / Principiu: The print stroke must be set correctly — greater than the logo width, but less than the cup circumference at the printing position. This ensures complete ink transfer without overlapping or missing areas.
Puncte cheie de reținut: The printing stroke is adjustable via the touchscreen PLC. Operators can fine‑tune the start and end positions based on the specific logo size and cup diameter. This flexibility makes the machine suitable for a wide range of pahar de plastic designs — from small logos on 4 oz cups to full‑wrap patterns on 32 oz pahare tip tumbler.
Leuze contrast sensor and servo motors for multi-color overprint upgrade on plastic cup screen printer
Operațiune: Cel/Cea/Cei/Cele red device on the left is a Leuze contrast sensor, which detects registration marks on the cup or screen. The black device on the right is a seam line sensor, which detects the paper cup seam to avoid printing over it.
Scop / Principiu: This is an optional upgrade package that enables multi‑color overprint on a single‑color machine. To achieve this, three components must work together:
① Leuze contrast sensor — detects registration marks for precise color‑to‑color alignment
② Servo motor (screen movement) — controls the screen frame left‑to‑right with high precision
③ Servo motor (fixture rotation) — controls the cup fixture rotation, synchronized with the screen
These three components work in coordinated motion to achieve high‑precision registration between colors. The seam line sensor is specifically for paper cups with a visible seam — it detects the seam and adjusts the print position to avoid printing over it.
Puncte cheie de reținut: Both sensors and the two additional servo motors are optional add‑ons, not part of the standard machine configuration. If you are printing single‑color jobs only, the standard JST-R300-ACSM without these upgrades is sufficient. For Starbucks‑style cups or other multi‑color designs, this upgrade is recommended.
Station 5: Inspection Station — Quality Check (Adjustment Use)
Operațiune: After printing, the cup passes through Station 5, which is used for visual inspection of the printed pattern.
Scop / Principiu: This station is primarily used during machine setup and adjustment. Operators can inspect the printed pattern for defects — such as misregistration, incomplete ink transfer, or blurred edges — without stopping the production line.
Puncte cheie de reținut: During normal high‑speed production, visual inspection may be performed periodically rather than on every cup. The station provides a convenient position for quality sampling without disrupting the workflow.
Station 6: UV Curing — Instant Ink Drying
UV curing station for plastic cup screen printing on Fully Automatic Screen Printing Machine
Operațiune: Immediately after printing, the cup enters the UV curing box, where UV‑LED light instantly cures the ink.
Scop / Principiu: UV inks are formulated to cure instantly when exposed to UV light. This provides immediate drying — no smudging, no waiting, no need for additional drying racks or ovens.
Puncte cheie de reținut: The UV curing time is adjustable via the touchscreen PLC. For different ink formulations and cup materials, the curing time may need to be fine‑tuned. UV LED curing is energy‑efficient şi safe for plastic cups, as it does not generate excessive heat that could deform the cup.
Station 7: Unloading — Automatic Cup Removal
Automatic unloading station with rubber suction pad for plastic cups on Fully Automatic Screen Printing Machine
Operațiune: O rubber suction pad picks up the finished cup from the fixture and transfers it to the outfeed conveyor.
Scop / Principiu: The rubber pad creates suction that lifts the cup off the fixture, then moves it to the conveyor for stacking. This method is gentle on printed surfaces — the rubber does not scratch or smudge the freshly cured logo.
Puncte cheie de reținut: When designing the cup fixture, do not make it too tight. If the fixture grips the cup too firmly, the suction may not provide enough force to remove the cup, causing unloading failures. The fixture should hold the cup securely during printing but release it easily during unloading.
⚠️ Failure handling: If a cup fails to be removed at Station 7, it continues to Station 8, where a sensor detects the presence of the cup and triggers a machine stop and alarm. The operator must manually remove the cup from Station 8 before restarting production.
Station 8: Stacking & Counting — Finished Product Collection
Automatic stacking and counting station for finished plastic cups on Fully Automatic Screen Printing Machine
Operațiune: After curing and unloading, finished cups travel along the conveyor to the stacking area. The stacking mechanism collects cups and pushes them to the storage area once a preset count is reached.
Scop / Principiu: Cel/Cea/Cei/Cele automatic stacking system eliminates manual counting and stacking labor. Cups are stacked to a user‑defined quantity, then automatically pushed to the storage area — ready for packaging.
Puncte cheie de reținut: The stacking count is fully adjustable via the touchscreen PLC. Operators can set the desired number per stack based on packaging requirements. The entire process — from feeding to stacking — is fully automated, requiring no manual intervention.
Întrebări frecvente (FAQ)
Q: Does this machine work for all types of plastic cups? A: The JST-R300-ACSM is specifically designed for tapered/conical plastic cups — both PP and PET — in sizes ranging from 4 oz to 32 oz. It is especially suitable for rimless plastic cups, which are common for pahare pentru smoothie, pahare pentru ceai cu fructeși pahare de călătorie. For pure cylindrical containers, we do not recommend this machine.
Q: Why does my printed logo peel off when I add ice cubes to the cup? A: This happens because standard screen printing inks become brittle and lose adhesion at low temperatures. For cold beverage applications — such as pahare reci în stil Starbucks or iced pahare pentru smoothie — we recommend low‑temperature resistant PP screen printing ink, which maintains adhesion in freeze tests down to ‑5°C to ‑10°C.
Q: What is the difference between the standard machine and the optional upgrade? A: The standard JST-R300-ACSM is a single‑color machine. The optional upgrade adds a Leuze contrast sensor + 2 servo motors, enabling multi‑color overprint with high registration precision. The upgrade also includes a seam line sensor for paper cups. All of these are add‑on components, not part of the standard configuration.
