Description

Technical Field

[0001] The invention relates to the technical field of plastic cup processing, in particular to a disposable plastic cup thermoforming device. Background Art

[0002] The principle of thermoforming is a secondary molding technology that uses thermoplastic plastic sheets as raw materials (sheets can be formed by extrusion or calendering). First, the sheet is cut into blanks of a certain size and shape, and then the blanks are clamped on a frame and heated to a softening temperature, that is, a high elastic-plastic state. Then, pressure is applied to bend and extend the blanks, and when they reach a certain shape, they are cooled and formed into open thin shell products. In most cases, the pressure applied to the blanks during the thermoforming process is by vacuuming and compressing the air (the pressure difference formed on both sides of the blanks, but various forms of mechanical pressure or hydraulic pressure can also be used).

[0032] The beneficial effects are: 1. The recycling device is cleverly installed on the top of the plastic cup making machine, so that there is no need to reel in the excess material first and then carry out the recycling work as in the past. This change has greatly reduced the labor intensity of workers. You know, the previous operation process was cumbersome, and workers needed to spend a lot of energy on reeling in the material, but now this link is omitted. At the same time, this installation method greatly improves the efficiency of the recycling of residual materials. In the traditional mode, due to the large number of steps, the connection between the various links may not be tight enough, which is easy to waste time, and the new method avoids these problems. Moreover, the recycled raw materials can be directly transported to the extruder, which enables the residual materials to be quickly recycled and reused. This efficient recycling and reuse mode achieves the effect of cost saving. Not only that, since the recycling device is installed on the top of the cup making machine, it does not take up too much extra space, making the layout of the entire production space more reasonable and compact.

[0033] 2. When the residual material is recycled and reused, the residual material will be placed in the cleaning tank to thoroughly remove impurities and dirt that may be attached to the surface of the residual material. Then, the cleaned residual material will be sent to the crushing part. Under the powerful action of the crushing part, the residual material will be broken down into smaller particles or fragments. This process needs to ensure that the particle size of the crushing is uniform. Finally, the crushed raw material will pass through the screening conveyor. The function of the screening conveyor is, on the one hand, to screen the crushed raw material, remove the oversized or undersized particles that do not meet the requirements, and ensure that the particle size of the raw material is within the appropriate range; on the other hand, it will stably transport the screened qualified raw materials to the extruder, where these raw materials will be melted and reprocessed, thereby realizing the recycling and reuse of the residual material and achieving the purpose of saving resources and reducing costs.

[0034] 3. The telescopic device is started, which can move the second drive motor and the electromagnet assembly. After the electromagnet assembly is started, it can be adsorbed with the corresponding magnet. The second drive motor is started, driving the electromagnet assembly, the magnet and the short rod to rotate, and driving the lead screw to rotate under the left and right of the first bevel gear and the second bevel gear to lift the cleaning piece out of the cleaning tank so as to clean the debris in the cleaning tank. In this way, the water quality inside the cleaning tank can be effectively improved. After the debris is cleaned out, the water quality becomes purer, so as to achieve the purpose of better cleaning the residual material. The coordinated operation of this whole set of devices is very effective in achieving the goal of improving the cleaning effect of the residual material. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Figure 1-Figure 5 As shown, a plurality of groups of auxiliary rollers 4 are rotatably arranged in the cleaning tank 1 and are spaced apart from each other. An input roller 5 is arranged on the top of the cleaning tank 1 away from the crushing part 2. The input roller 5 can input the residual material produced by the plastic paper cup machine into the cleaning tank 1. A driving motor 6 that can drive the input roller 5 to rotate is fixedly arranged on the outside of the cleaning tank 1. An output roller 7 is arranged on the top of the cleaning tank 1 close to the crushing part 2. An output mounting seat is fixedly arranged on the top of the cleaning tank 1 close to the crushing part 2. The output roller 7 rotates on the output mounting seat.

The structure and principle of the electromagnet and the battery are prior art and will not be described in detail here.

[0065] Working principle: The device is installed on the top of the plastic cup making machine by bolts. The feed port of the cleaning tank 1 corresponds to the discharge port of the plastic cup making machine. The residual material generated by the plastic cup making machine can enter the cleaning tank 1. The screening conveyor 3 is connected to the input port of the extruder, and the processed material can be conveyed to the extruder for reuse; the driving motor 6 is started, which can drive the first roller 501 to rotate to convey the residual material. At this time, the residual material is located above the input roller 5. When the first roller 501 rotates, it can also drive the fourth sprocket 12 to rotate, so that the fourth sprocket 12 drives the third sprocket 11 to rotate through the second chain. When a group of auxiliary rollers 4 closest to the second roller 502 rotates, the fifth sprocket 13 is set to drive the adjacent auxiliary rollers 4 to rotate, and then drive the group of auxiliary rollers 4 closest to the second roller 502 to rotate.

Since the two first gears 15 are meshed with each other, when one of the crushing knives 202 rotates, the other crushing knives 202 can be rotated in the opposite direction, so that the residual material is crushed by the relative rotation of the two crushing knives 202; the crushed material flows into the screening conveyor 3, and through the setting of the leak plate 302 and the screening frame 301, the larger particles flow to the return plate 19, and then are crushed again, while the qualified material will flow to the screening frame 301 through the leak plate 302, and then flow to the conveying plate 18 for reprocessing by the extruder.

[0066] After the telescopic device 25 is started, it can drive the second drive motor 26 and the electromagnet assembly 27 to move to the corresponding magnet 24. After the electromagnet assembly 27 is started, it can adsorb the magnet 24 on the corresponding short rod 23, so that when the output shaft of the second drive motor 26 rotates, the corresponding magnet 24 and the short rod 23 can be driven to rotate through the electromagnet assembly 27. When the short rod 23 rotates, it can drive the corresponding second bevel gear 2103 to rotate, and the second bevel gear 2103 is meshed with the first bevel gear 2102, so it can press the corresponding lead screw 2101 to rotate. When the lead screw 2101 rotates, the cleaning member 22 can move up and down along the sliding limit groove 20 to salvage the debris in the cleaning tank member 1.

[0067] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
