[0032] An embodiment of the present application provides a device for preparing a plastic cup.
[0033] like Figure 1 and Figure 2 As shown, a plastic cup preparation device includes a sheet forming mechanism 1 and a cup body forming mechanism 2.
[0034] The sheet forming mechanism 1 includes a plastic sheet extruder 11, a die head 12, a three-roll calender 13 and a first traction assembly 14. The plastic sheet extruder 11 is used to extrude the molten plastic from the die head 12 and then flatten it through the three-roll calender 13 to form a plastic sheet. The first traction assembly 14 is used to provide forward traction power for the formed plastic sheet.
[0035] The plastic particles are heated to a molten state in the plastic sheet extruder 11 and then extruded from the die 12. The sheet-shaped high-temperature plastic extruded from the die 12 is pressed and cooled by the three-roll calender 13 to form a plastic sheet. The first traction component 14 includes an active roller and a driven roller. The active roller and the driven roller clamp the plastic sheet cooled by the three-roll calender 13. The active roller is driven to rotate by a motor. The rotation of the active roller drives the plastic sheet to move continuously and transports the sheet to the cup body forming machine.
[0036] The cup body forming mechanism 2 includes a positive pressure blister forming machine, a cutting component, a discharging component and a sheet waste winding component 21. The plastic sheet passing through the first traction component 14 enters the positive pressure blister forming machine. The positive pressure blister forming machine is used to form plastic cups on the plastic sheet. The cutting component is used to separate the plastic cups from the plastic sheet. The discharging component is used to transfer the plastic cups separated from the plastic sheet from the cutting component. The sheet waste winding component 21 is used to wind and recycle the plastic sheet after the plastic cups are separated.
[0037] Since the plastic sheet has only been cooled by the three-roll calender 13, the temperature of the plastic sheet is still at 60-90°C. The plastic sheet has not been cooled and hardened and is still in a softened state. The softened plastic sheet is pressed against the mold of the positive pressure blister molding machine, and compressed air is injected into the mold. The pressure range of the compressed air is 0.7-1.5MPa, and the sheet is pressed into the mold cavity to form a plastic cup body. The formed plastic cup body is solidified after air cooling or water cooling to stabilize its shape. The plastic cup body with a stable shape is still connected to the sheet waste. The plastic cup body is separated from the sheet waste by the cutting component, and the sheet waste is wound and collected by the sheet waste winding component 21. There are two ways to discharge the component: 1. The plastic cup body separated from the sheet waste is still in the mold cavity. An air outlet is provided at the bottom of the mold cavity. Compressed air is blown into the mold cavity through the air outlet to blow the quilt out of the mold cavity; 2. The plastic cup in the mold cavity is removed by using a robotic arm plus a suction cup or a robotic arm plus a gripper.
[0038] In the prior art, after the plastic extruded from the die 12 passes through the three-roll calender 13, the plastic sheet is still in a softened state. To complete the winding, a second cooling is required to cool the sheet to room temperature. In the embodiment of the present application, the plastic sheet that has passed the three-roll calender 13 is directly introduced into the positive pressure blister molding machine, eliminating the second cooling and winding process of the sheet molding machine in the prior art and the structures involved in the two processes. The plastic sheet that has passed the three-roll calender 13 is still in a softened state, so it can directly enter the positive pressure blister molding machine for heat preservation molding, eliminating the unwinding and oven preheating processes of the cup molding machine in the prior art and the structures involved in the two processes. The plastic cup preparation device of the present application connects the sheet molding machine and the cup molding machine, and eliminates the second cooling and winding of the sheet molding process and the unwinding and oven preheating of the cup molding process, saving energy consumed by cooling and preheating, and reducing the cost of processes and manufacturing equipment.
[0039] It should be noted that the plastic sheet extruder 11, die head 12, three-roll calender 13, and first traction assembly 14 in the sheet forming mechanism 1 are well-established in the prior art and do not constitute the novelties of this application. The embodiments of this application will not be described in detail here. The positive pressure blister forming machine, cutting assembly, discharge assembly, and sheet waste winding assembly 21 of the cup forming mechanism 2 are well-established in the prior art and their specific structures do not constitute the novelties of this application. The embodiments of this application will not be described in detail here.
[0040] In the embodiment of the present application, the distance between the three-roll calender 13 and the positive pressure blister molding machine is 2-3 meters; by controlling the distance between the three-roll calender 13 and the positive pressure blister molding machine, the plastic sheet entering the positive pressure blister molding machine will not be too soft or too hard. The plastic sheet extruder 11 is a twin-screw basic sheet extruder.
[0041] The plastic cup preparation device also includes an automatic stacking machine 3, a transfer mechanism 4 and a plastic cup printing machine 5; the feed port of the automatic stacking machine 3 is used to receive the plastic cups transferred out by the discharge component, and stack multiple independent plastic cups to form multiple groups of stacked plastic cups, and the transfer mechanism 4 is used to transfer the stacked plastic cups to the feed port of the plastic cup printing machine 5.
[0042] The present application transfers plastic cups to the entrance of a plastic cup printing machine 5 through an automatic stacking machine 3 and a transfer mechanism 4, eliminating manual transfer, saving labor, and reducing the risk of contamination of the plastic cups. The automatic stacking machine 3, also known as an automatic cup sorting machine, operates as follows: a cup falls onto an upwardly inclined conveyor belt, with the cup's open flange resting on two adjacent conveyor belts, and the entire cup body located below the conveyor belts. The conveyor belts convey the plastic cups, which pass through a reverse sweeping brush. A plastic cup with its open cup body facing upward and located below the conveyor belts passes through the reverse sweeping brushes normally. If the cup rests horizontally between the two conveyor belts, i.e., the entire cup is located above the conveyor belts, the cup cannot pass through the reverse sweeping brushes and is pushed away by the reverse sweeping brushes, adjusting the cup's posture. The plastic cups passing through the reverse sweeping brush gradually tilt, and the opening of the cup faces the stacking station of the automatic stacking machine 3, and then arrive at the stacking station of the automatic stacking machine 3. The subsequent cups have their openings facing the stacking station and are sleeved on the outer periphery of the cups that arrived first. There are multiple conveyor belts and multiple stacking stations. Each stacking station corresponds to a position between two adjacent conveyor belts. The automatic stacking machine 3 for plastic cups based on the above principle is an existing mature technology, and the specific structure of the embodiment of this application will not be described in detail here.
[0043] like Figure 2 、 Figure 3 and Figure 4As shown, the transfer mechanism 4 includes a cup pushing component 41, a transverse movement component 42 and a conveying component 43; the transverse movement component 42 includes a transverse movement conveyor belt 421 and a plurality of spaced accommodating grooves 422 located on the transverse movement conveyor belt 421, the accommodating grooves 422 are aligned with the stacking station on the automatic stacking machine 3, the cup pushing component 41 is used to push the partially stacked plastic cup stacks into the accommodating grooves 422 when the number of plastic cups on the stacking station reaches a preset value, the conveying direction of the transverse movement component 42 is perpendicular to the stacking direction of the plastic cups, the feeding section of the conveying component 43 is located below the discharging end of the transverse movement component 42, the transverse movement component 42 is used to transport multiple plastic cup stacks to the feeding section of the conveying component 43 in sequence, and the discharging end of the conveying component 43 is connected to the feeding conveyor belt of the plastic cup printing machine 5. Among them, the receiving groove 422 is a V-shaped plate, which is fixed on the surface of the transverse conveyor belt 421. The cup pushing assembly 41 and the transverse moving assembly 42 work alternately. The receiving groove 422 on the transverse moving assembly 42 above the transverse conveyor belt 421 opens upward, and the receiving groove 422 below the conveyor belt opens downward. Initially, the plastic cups are gradually stacked. At this time, the receiving groove 422 of the transverse moving assembly 42 is aligned with the stacking station of the automatic stacking machine 3. As the number of cups increases, the later cups continuously push the earlier cups to continue moving forward at the stacking station. When the cups are stacked to a preset number, the cup pushing assembly 41 pushes the fixed number of plastic cups into the receiving groove 422 as a whole, and the cups enter the receiving groove from one end of the receiving groove 422. The cups are placed in the trough 422, and then the cup pushing assembly 41 retreats, and the transverse conveyor belt 421 of the transverse assembly 42 starts. As the transverse conveyor belt 421 moves, the accommodating trough 422 gradually moves, and the accommodating trough 422 above the transverse conveyor belt 421 approaches the end of the transverse conveyor belt 421 and moves to the bottom of the transverse conveyor belt 421. The accommodating trough 422 changes from opening upward to opening downward. The cups originally located in the accommodating trough 422 fall onto the feeding section of the conveying assembly 43. Multiple accommodating troughs 422 containing plastic cups approach the end of the transverse conveyor belt 421 in turn, and multiple plastic cup stacks fall on the conveying assembly 43 in turn. The conveying assembly 43 then conveys the plastic cups to the inlet of the plastic cup printing machine 5.
[0044] like Figure 4As shown, the cup pushing assembly 41 includes a detection sensor, a horizontal moving cylinder 411, a vertical moving cylinder 412 and a push plate 413. The horizontal moving cylinder 411 is fixed above the stacking station on the automatic stacking machine 3, and the vertical moving cylinder 412 is fixed on the output end of the horizontal moving cylinder 411. A plurality of grooves 414 are provided on the push plate 413, one groove 414 corresponds to one stacking station, the groove 414 matches the outer periphery of the plastic cup, and the edge of the groove 414 is used to abut the convex edge of the cup mouth of the plastic cup. The detection sensor includes an infrared transmitter located above the stacking station and an infrared receiver located below the stacking station. The infrared transmitter emits infrared light that shines on the infrared receiver. By adjusting the position of the detection sensor on the stacking station, the plastic cups are continuously stacked, and the plastic cup at the front continuously moves forward until the plastic cup blocks the infrared light. If the infrared receiver does not receive the infrared light emitted by the external transmitter, it means that the number of plastic cups on the stacking station has reached the preset value. The vertical moving cylinder 412 controls the push plate 413 to move downward. The groove 414 of the push plate 413 is located on the outer periphery of the plastic cup. The horizontal moving cylinder 411 is started, and the push plate 413 is pressed against the convex edge of the cup mouth of the plastic cup, pushing the stacked plastic cups forward into the receiving groove 422. Then the horizontal cylinder and the vertical moving cylinder 412 are reset. At this time, the push plate 413 is farther away from the receiving groove 422 than the detection sensor. The distance between the push plate 413 and the detection sensor is the maximum amount of plastic cups pushed by the push plate 413 each time. Each stacking station is equipped with a detection sensor. As long as the number of plastic cups at a stacking station reaches the preset value, the plastic cups at all stacking stations are pushed together to the receiving groove 422. The above description only explains the principle of the cup pusher assembly 41. The cup pusher assembly 41 based on the above principle is a mature solution in the existing technology. The specific design of the cup pusher assembly 41 is not the innovation of this application. Instead, the cup pusher assembly 41 is used to transfer the plastic cup. The embodiment of this application does not provide a detailed description of the specific structure of the cup pusher assembly 41.
[0045] The feed inlet of the plastic cup printing machine 5 is provided with a feed conveyor belt, and the height of the feed conveyor belt is greater than 1.8 meters. The present application raises the feed inlet of the plastic cup printing machine 5, reducing the risk of contamination by employees passing through the plastic cups.
[0046] like Figure 5 As shown, the conveying component 43 is a belt screw conveyor, the feed section of the belt screw conveyor is located below the discharge end of the transverse movement component 42, and the conveying direction of the feed section of the belt screw conveyor is perpendicular to the conveying direction of the transverse movement component 42. The transverse movement component 42 is used to transport multiple plastic cup stacks to the feed section of the belt screw conveyor, and the discharge end of the belt screw conveyor is connected to the feed conveyor belt of the plastic cup printing machine 5.
[0047] The discharging section of the transmission component is provided with a diverter component 44, the feeding section of the diverter component 44 is connected to the discharging section of the transmission component, and the diverter component 44 is provided with multiple discharging conveyor belts, each of which is provided corresponding to one of the plastic cup printing machines 5, and the discharging conveyor belt is connected to the feeding conveyor belt of the plastic cup printing machine 5. In the implementation of this application, the diverter component 44 has one feeding conveyor belt and two discharging conveyor belts, one end of the feeding conveyor belt is connected to the discharging section of the transmission component, and the other end of the feeding conveyor belt is connected to the two discharging conveyor belts. A lever is provided on the feeding conveyor belt, one end of the lever is rotatably positioned between the two discharging conveyor belts, and the other end of the lever is freely set. When the lever is moved to the entrance position of one of the discharging conveyor belts, the discharging conveyor belt is blocked, and the incoming material can only enter the other discharging conveyor belt, thereby realizing the diversion of the plastic cups. In other embodiments, the diverter assembly 44 comprises an infeed conveyor and at least three outfeed conveyors. The infeed conveyor is provided with two opposing guide plates that gradually approach each other along the conveying direction. A movable plate is positioned behind each guide plate. The movable plate intersects the guide plates. By rotating the movable plate, the area between the two movable plates can be aligned with any of the outfeed conveyors, allowing the incoming material to enter different outfeed conveyors. Furthermore, a detection device is provided at the entrance of each plastic printing press to detect excess material at the entrance and, in conjunction with a controller, to control the diverter assembly 44 accordingly.
[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
