Description

Technical Field

[0001] This utility model relates to the field of plastic manufacturing technology, specifically to a plastic shaping and packaging mechanism. Background Technology

[0002] After the plastic product preform produced by the high-speed molding machine is punched and sheared by the punching and shearing machine, the plastic product enters the cup drop tube through the die hole of the punching and shearing mold. The cup body that comes out of the cup drop tube enters the cup blowing table. In the cup blowing table, packaging workers carry out manual packaging operations. The operation requires manual actions such as picking up the cup, blowing the cup, and bagging.

[0003] A plastic cup making machine disclosed in Chinese Invention Patent Application Publication No. CN109866370A simplifies cumbersome operating steps and has a high degree of automation through a crushing box and a heating and melting box for processing raw materials. It can save a lot of manpower and resources, effectively increase the production capacity of plastic cups, reduce the production cost of plastic cups, improve the production efficiency of plastic cups, and increase the production profit of plastic cups. However, the existing device does not solve the problem that some uncut plastic products tend to stick to the plastic waste during the shaping process. Directly discarding the waste with sticky plastic products is wasteful. After the plastic products are made, due to the large number of plastic products, they also need to be collected and stacked. Manual collection of these products is time-consuming and labor-intensive. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0012] Optionally, a collection seat is snapped onto the upper surface of the equipment base plate, the collection seat being located on the upper surface of the equipment base plate near the rotating wheel, and a sealing machine is fixedly connected to the upper surface of the equipment base plate, the sealing machine being located on the upper surface of the equipment base plate near the thermoforming machine.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. This utility model has a reasonable structure. By fixing a plastic sheet to the feeding structure, and then passing one end of the plastic sheet through the thermoforming machine and fixing it to the receiving structure, the plastic sheet is collected by driving the receiving structure, allowing for tensioned conveying. Then, through the thermoforming machine, mold structure, lifting mechanism, vacuum assembly, and blowing structure, the plastic sheet is processed into plastic products. Simultaneously, the finished plastic products are blown out from inside the thermoforming machine and fall onto the conveyor belt. During the waste collection process of the receiving structure, the support motor drives the support screw, causing the support slider and limit rod to move continuously in parallel, thus scraping off any remaining plastic products on the waste material, reducing waste. When shaping plastic products, some uncut plastic parts easily stick to the plastic waste. Directly discarding the waste with stuck plastic parts is wasteful. This solution allows for the removal of stuck plastic parts by a limiting rod, which then drops them onto a conveyor belt. A fixed motor rotates a fixed shaft, causing the pulley to rotate, which in turn moves the plastic parts on the belt. Because the distance between the two belts is matched to the diameter of the wider opening of the plastic part, the smaller opening of the plastic part faces downwards and the larger opening faces upwards during transport.

[0014] 2. In this utility model, a baffle intercepts the plastic products during the conveying process. A hydraulic device moves the connecting frame downwards until the suction cup inserts into the inner bottom wall of the plastic product, thus adsorbing the plastic product. The hydraulic device then moves the connecting frame and the plastic product upwards. A positioning motor drives the positioning screw, causing the positioning slider to move parallel until the plastic product is moved above the collecting seat. At this point, the hydraulic device moves the connecting frame downwards, allowing the plastic product to enter the collecting seat. The suction cup releases its grip on the plastic product, causing it to fall into the collecting seat. Repeating the above operations completes the stacking and collection of finished plastic products. After collection, the collection seat is separated from the equipment base plate and placed around the sealing machine. The placement slot can hold the packaging bags. The operator transfers the stacked plastic products into the packaging bags, and then the sealing machine seals the packaging bags after the plastic products are placed in them. This completes the packaging of the plastic products and reduces the time-consuming and labor-intensive process of manually collecting the large number of plastic products after production. It achieves the effect of automatically stacking and collecting the produced plastic products through suction cups and collection seats, and finally, the operator seals the collected plastic products.

A baffle 15 is fixedly connected to the upper surface of the equipment base plate 1. A support rod 16 is fixedly connected to one side of the thermoforming machine 2. A support base 17 is fixedly connected to one side of the support rod 16. A support motor 18 is fixedly connected inside the support base 17. A support screw 19 is inserted into one end of the support motor 18. A support slider 20 is threaded through the surface of the support screw 19.

[0019] As a preferred embodiment of this example, Figures 1-5As shown, a thermoforming machine 2 is fixedly connected to the upper surface of the equipment base plate 1. A feeding structure 3 is provided on the upper surface of the thermoforming machine 2. A mold structure 4 is installed inside the thermoforming machine 2. A lifting mechanism 5 is installed inside the thermoforming machine 2. A vacuum assembly 6 is installed inside the thermoforming machine 2. A blowing structure 7 is provided on one side of the thermoforming machine 2. The vacuum assembly 6 and the mold structure 4 are compatible. The blowing structure 7 can blow air from inside the thermoforming machine 2 to the outside. A receiving structure 8 is installed on the upper surface of the thermoforming machine 2. A bracket 9 is fixedly connected to the upper surface of the equipment base plate 1. A fixed motor 10 is fixedly connected inside the bracket 9. A fixed rotating shaft 11 is inserted into one end of the fixed motor 10. A rotating wheel 12 is fixedly connected to the surface of the fixed rotating shaft 11. A belt 1 is sleeved on the surface of the rotating wheel 12. 3. Both belt 13 and pulley 12 are located between bracket 9 and positioning frame 14. There are several belts 13 and pulleys 12. The positioning frame 14 is rotatably connected to the surface of fixed shaft 11. A baffle 15 is fixedly connected to the upper surface of equipment base plate 1. A placement groove is opened on the upper surface of equipment base plate 1. The baffle 15 is located below belt 13. A support rod 16 is fixedly connected to one side of thermoforming machine 2. A support base 17 is fixedly connected to one side of support rod 16. A support motor 18 is fixedly connected inside support base 17. A support screw 19 is inserted into one end of support motor 18. A support slider 20 is threaded through the surface of support screw 19. A support groove is opened on the lower surface of support base 17. The support base 17 is positioned relative to the support slider 20 through the support groove. A limiting rod 21 is fixedly connected to one side of the support slider 20. The limiting rod 21 is located on one side of the support slider 20 near the thermoforming machine 2. During use, the plastic sheet is fixed to the feeding structure 3, and one end of the plastic sheet is passed through the thermoforming machine 2 and fixed to the receiving structure 8. The receiving structure 8 is driven to collect the plastic sheet, thereby tensioning and conveying the plastic sheet. Then, through the thermoforming machine 2, mold structure 4, lifting mechanism 5, vacuum component 6, and blowing structure 7, the plastic sheet is made into a plastic product. At the same time, the finished plastic product is blown out from inside the thermoforming machine 2 and falls onto the belt 13. During the process of collecting waste material in the receiving structure 8, the support motor 18 drives the support screw 19 to keep the support slider 20 and the limiting rod 21 continuously level. The movement of the belt allows for the scraping off of any plastic products that haven't fallen off the waste material. This reduces the likelihood of uncut plastic products sticking to the waste material during the manufacturing and shaping process, which would otherwise be wasteful to discard. The belt 13 effectively scrapes off any plastic products stuck to the waste material using the limiting rod 21, causing them to fall onto the belt. The fixed motor 10 rotates the fixed shaft 11, causing the wheel 12 to rotate, which in turn causes the belt 13 to move the plastic products on its surface. Since the distance between the two belts 13 is matched to the diameter of the wider opening of the plastic product, the smaller opening of the plastic product faces downwards and the larger opening faces upwards during the conveying process.

[0020] like Figure 4 and Figure 6 As shown, in this embodiment, a positioning rod 22 is fixedly connected to the upper surface of the equipment base plate 1, a positioning seat 23 is fixedly connected to the upper surface of the positioning rod 22, a positioning motor 24 is fixedly connected inside the positioning seat 23, a positioning screw 25 is inserted into one end of the positioning motor 24, a positioning slider 26 is threaded through the surface of the positioning screw 25, a positioning groove is formed on the lower surface of the positioning seat 23, and the positioning seat 23 is slidably connected to the positioning slider 26 through the positioning groove. A hydraulic device 27 is fixedly connected to the lower surface of the positioning slider 26, and a connecting frame 28 is fixedly connected to the lower surface of the hydraulic device 27. A suction cup 29 is fixedly connected to the lower surface of the frame 28, and a collection seat 30 is snapped onto the upper surface of the equipment base plate 1. The collection seat 30 is located on the upper surface of the equipment base plate 1 near the rotating wheel 12. A sealing machine 31 is fixedly connected to the upper surface of the equipment base plate 1, located on the upper surface of the equipment base plate 1 near the thermoforming machine 2. During use, the baffle 15 intercepts the plastic products during the conveying process, and the hydraulic device 27 moves the connecting frame 28 downward until the suction cup 29 inserts into the inner bottom wall of the plastic product, thereby adsorbing the plastic product through the suction cup 29. Then, the hydraulic device 27... The connecting frame 28 and the plastic product are moved upwards. Then, the positioning motor 24 drives the positioning screw 25, causing the positioning slider 26 to move parallel until the plastic product is moved above the collecting seat 30. At this point, the hydraulic device 27 moves the connecting frame 28 downwards, allowing the plastic product to enter the collecting seat 30. The suction cup 29 releases its grip on the plastic product, causing it to fall into the collecting seat 30. Repeating the above operation completes the stacking and collection of finished plastic products. After the plastic products are stacked and collected, the collecting seat 30 is separated from the equipment base plate 1 and placed around the sealing machine 31. The placement slot can hold the packaging bags. The operator transfers the stacked plastic products into the packaging bags, and then the sealing machine 31 seals the packaging bags after the plastic products are placed in them, thus completing the packaging of the plastic products. This reduces the time-consuming and laborious process of manually collecting the large number of plastic products after they are made, which requires stacking them manually. The system achieves the effect of automatically stacking and collecting the finished plastic products through the suction cup 29 and the collection seat 30, and then having the operator seal the collected plastic products.

[0021] The working principle of this practical application is as follows: During use, the plastic sheet is fixed to the feeding structure 3, and one end of the plastic sheet is passed through the thermoforming machine 2 and fixed to the receiving structure 8. The receiving structure 8 is driven to collect the plastic sheet, thus allowing for tensioned conveying. The plastic sheet is then processed into plastic products through the thermoforming machine 2, mold structure 4, lifting mechanism 5, vacuum assembly 6, and blowing structure 7. The finished plastic products are blown out from inside the thermoforming machine 2 and fall onto the belt 13. During the waste collection process of the receiving structure 8, the support motor 18 drives the support screw 19, causing the support slider 20 and limit rod 21 to move continuously in parallel, thus scraping off any plastic products that have not fallen off the waste. The fixed motor 10 rotates the fixed shaft 11, causing the wheel 12 to rotate, which in turn causes the belt 13 to move the plastic products on its surface. Since the distance between the two belts 13 is adapted to the diameter of the wider opening of the plastic product, the smaller opening of the plastic product faces downwards and the larger opening (i.e., the opening position of the plastic product) faces upwards during conveying. The baffle 1... 5. To intercept plastic products during the conveying process, the hydraulic device 27 moves the connecting frame 28 downward until the suction cup 29 inserts into the inner bottom wall of the plastic product, thus adsorbing the plastic product through the suction cup 29. Then, the hydraulic device 27 moves the connecting frame 28 and the plastic product upward. Then, the positioning motor 24 drives the positioning screw 25 to move the positioning slider 26 parallel until the plastic product is moved above the collection seat 30. At this time, the hydraulic device 27 moves the connecting frame 28 downward, allowing the plastic product to enter the collection seat 30. The suction cup 29 releases its adsorption on the plastic product, allowing the plastic product to fall into the collection seat 30. Repeating the above operation completes the stacking and collection of finished plastic products. After the plastic products are stacked and collected, the collection seat 30 is separated from the equipment base plate 1 and placed around the sealing machine 31. The placement slot can place the sealing bag. The operator transfers the stacked plastic products into the sealing bag, and then the sealing machine 31 seals the sealing bag after placing the plastic products, thus completing the sealing of the plastic products.
