A plastic product processing corner waste recycling device

Abstract

The application relates to the technical field of plastic product processing, and specifically provides a plastic product processing leftover material recycling device. The plastic product processing leftover material recycling device disclosed by the application comprises an outer cylinder, an inner cylinder, a feeding mechanism, a crushing mechanism, an air inlet channel, an air duct plugging mechanism and a leftover material collecting mechanism. The air duct plugging mechanism is connected with the transmission shaft on the crushing mechanism, thereby achieving intermittent plugging of the air inlet channel. When the air inlet channel is opened, airflow is directly connected to the collecting box, and the fully crushed leftover material is quickly discharged. When the air inlet channel is plugged, airflow is diverted upwards to blow through the leakage hole, thereby pushing the insufficiently crushed leftover material into contact with the blade II to perform secondary crushing. The fully crushed leftover material can pass through the leakage hole into the air inlet channel, or pass through the annular filter plate and the feeding pipe into the air inlet channel, thereby achieving double-path quick discharge and reducing the residence of the fully crushed leftover material.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic product processing, and particularly relates to a plastic product processing leftover material recycling device. BACKGROUND

[0002] With the popularity of the take-out industry, the use of disposable plastic meal boxes and tableware is increasing. The production of disposable tableware usually includes the steps of raw material melting, sheet forming, tableware vacuum forming, and product inspection. After vacuum forming of the sheet, the finished product is removed, and the leftover material is obtained. Since the tableware is formed by vacuum forming of the sheet, the leftover material is a continuous strip.

[0003] At present, when the leftover material is crushed, the leftover material is first wound by a winding roller to make the leftover material into a roll shape, and then crushed. However, the leftover material is very thick after winding, and it is not easy to crush into small particles. The entire crushing process takes a very long time, and the crushing efficiency is low.

[0004] Chinese patent document CN220547056U discloses a leftover material crushing device for disposable tableware production. The device solves the problem of crushing the leftover material after winding, which is very thick and difficult to crush, affecting subsequent recycling. The device blows the leftover material that has not been crushed or has not been fully crushed to the upper part of the inner cavity of the leakage cylinder, and the leftover material is crushed again by the knife roller. The leftover material is fully crushed.

[0005] The leftover material crushing device described above solves the problem of incomplete crushing to some extent, but still has the following problems: the airflow blows the leftover material that has not been crushed or has not been fully crushed to the upper part of the inner cavity of the leakage cylinder, and the leftover material is crushed again by the knife roller. However, the fully crushed leftover material is also blown to the upper part of the inner cavity of the leakage cylinder, and cannot be separated and discharged in time, which easily causes the leftover material to be over-crushed, resulting in a balance between crushing efficiency and quality.

[0006] In order to discharge the fully crushed leftover material in real time and ensure that the insufficiently crushed leftover material is intercepted and crushed again, we propose a plastic product processing leftover material recycling device. SUMMARY

[0045] As shown in Figures 5-7 The feeding mechanism 3 comprises a feeding roller 31, the feeding roller 31 is rotatably installed in the inner cylinder 2, the feeding roller 31 is provided in two groups and the two groups of feeding rollers 31 are symmetrically arranged in the inner cylinder 2, the two feeding rollers 31 are in contact with each other, a second motor 32 is arranged on the side wall of the inner cylinder 2, the output end of the second motor 32 penetrates through the inner cylinder 2 and is connected with one of the two groups of feeding rollers 31, and a feeding opening 33 is formed in the top of the inner cylinder 2.

[0046] As shown in Figures 5-7 The feeding mechanism 3 further comprises a material guiding table 34, the material guiding table 34 is fixedly arranged in the inner cylinder 2, the feeding roller 31 is located above the material guiding table 34, a guide groove 35 is formed in the middle of the upper surface of the material guiding table 34, and a limiting hole 36 is formed in the middle of the lower surface of the guide groove 35.

[0047] The working principle of the feeding mechanism 3 is as follows: the two feeding rollers 31 can be in close contact and the relative rotation of the two feeding rollers 31 can be realized through the rubber sleeve sleeved on the surface of the feeding roller 31, the edge material can be pressed tightly through the rubber sleeve, the edge material can be driven to move downward under the action of friction, and the edge material can enter the inner cylinder 2 and the two groups of crushing rollers 43 through the guide groove 35 and the limiting hole 36 on the material guiding table 34.

[0048] The downward conveying side material can be guided into the limiting hole 36 through the guide slot 35 on the material guide table 34, so that the downward conveying side material is crushed by the blade 48.

[0049] As shown in Figures 8-9 The side material collecting mechanism 7 includes a collecting box 71, one side of which communicates with the air inlet channel 5, a filter screen 72 is horizontally installed inside the collecting box 71, and the filter screen 72 is located above the position where the air inlet channel 5 communicates with the collecting box 71, the filter screen 72 is horizontally installed, an air outlet 73 is arranged at the top of the collecting box 71, a discharge port is arranged at the bottom of the collecting box 71, and a sealing door 74 is arranged at the discharge port. During the crushing and collecting process of the side material, the sealing door 74 is closed, and when the crushing is completed, the sealing door 74 is opened, and the crushed side material in the collecting box 71 is taken out.

[0050] When the blocking plate 67 does not block the air inlet channel 5, the airflow of the air inlet channel 5 drives the fully crushed side material into the collecting box 71; when the blocking plate 67 blocks the air inlet channel 5, the area of the air inlet channel 5 between the collecting box 71 and the outer cylinder 1 is blocked at this time, and at this time, the airflow of the air inlet channel 5 can only flow into the outer cylinder 1 through the leakage hole 9. The airflow passing through the leakage hole 9 blows the side material not fully crushed at the leakage hole 9 from bottom to top, the upwardly blown side material contacts the blade two 49 to be crushed again, and after the upwardly blown side material is crushed by the blade two 49, the side material not fully crushed is blocked by the annular filter plate 12 after passing through the annular filter plate 12, and the fully crushed side material enters the air inlet channel 5 through the feeding pipe 11 and then enters the collecting box 71. By intermittently blocking the air inlet channel 5 through the blocking plate 67, the fully crushed side material can enter the air inlet channel 5 through the leakage hole 9 and the annular filter plate 12 and the feeding pipe 11, so that the fully crushed side material can enter the collecting box 71 as soon as possible, the crushing time of the side material is reduced, and the over-crushing of part of the side material is avoided, which affects the subsequent recovery and causes excessive dust during production. The size specification of the leakage hole 9 and the size specification of the filter hole on the annular filter plate 12 are the same, and only the fully crushed side material can pass through.

[0051] As shown in Figures 1-2 The communication position of the feeding pipe 11 and the outer cylinder 1 is above the annular filter plate 12, and the communication position of the feeding pipe 11 and the top of the air inlet channel 5 is between the blocking plate 67 and the collecting box 71, so that the upwardly blown side material can be blocked and filtered by the annular filter plate 12, and the side material passing through the annular filter plate 12 can enter the air inlet channel 5 along the feeding pipe 11 and finally enter the collecting box 71.

[0052] As shown in Figures 5-7As shown, the support partition plate 13 is provided with a material guide slope 411 on the top of the front and rear sides, which is attached to the outer side wall of the inner cylinder 2 and the inner wall of the outer cylinder 1, and the material guide slope 411 is downward from the middle to the two ends, and the material leakage hole 9 is located on the left and right sides of the inner cylinder 2 and between the two ends of the two groups of material guide slopes 411. Through the material guide slope 411, the edge material falling from the discharge port 8 can be guided to the material leakage hole 9, which facilitates the discharge of the edge material from the material leakage hole 9, and the airflow sprayed from the material leakage hole 9 can also blow the incompletely crushed edge material upward for secondary crushing.

[0053] In specific use, when the processing edge material of the plastic product is crushed and recycled, the end of the rolled edge material is placed between the two feeding rollers 31 through the feeding port 33, and the motor two 32 is started to drive one of the feeding rollers 31 to rotate. The two feeding rollers 31 can be in close contact through the rubber sleeve on the surface of the feeding roller 31, so that the relative rotation of the two feeding rollers 31 can be realized, and the edge material is pressed by the rubber sleeve, and at the same time, the edge material is driven downward under the action of friction and enters the inner cylinder 2 through the guide groove 35 and the limiting hole 36 on the material guide table 34 and between the two groups of crushing rollers 43;

[0054] At the same time, the motor one 47 is started to drive the transmission shaft 41 to rotate, thereby driving the bevel gear two 46 to rotate, the bevel gear one 45 to rotate, the center shaft 44 to rotate, and the two groups of crushing rollers 43 to rotate at high speed, and the blade one 48 on the crushing roller 43 crushes the edge material.

[0055] The crushed edge material will slide along the conical table 42 to the discharge port 8, and the cleaning rod 410 will clean and scrape off the edge material on the top of the conical table 42. The edge material falls between the outer cylinder 1 and the inner cylinder 2 through the discharge port 8, and then slides to the material leakage hole 9 through the material guide slope 411. The edge material that is not fully crushed and not crushed in time will be intercepted above the material leakage hole 9, and the fully crushed edge material will pass through the material leakage hole 9 and the feeding port 10 into the air inlet channel 5 in turn.

[0056] At the same time, the air inlet channel 5 is connected with the air blower, the air blower sends gas into the air inlet channel 5, the gas flows from the right end to the left end of the air inlet channel 5, and drives the fully crushed edge material into the collection box 71, and the gas is filtered by the filter screen 72 in the collection box 71 and discharged from the air outlet 73, while the edge material remains at the bottom of the collection box 71.

[0057] Meanwhile, when the transmission shaft 41 rotates, the incomplete gear 63 is also driven to rotate at a reduced speed by the speed reducer 62. When the incomplete gear 63 meshes with the driven gear 64, the driven gear 64 is driven to rotate, and in turn, the rotating shaft 68 and the rope winding wheel 65 are driven to rotate. The rope winding wheel 65 winds the pull rope 66, and in turn, the baffle 69, the blocking plate 67 and the guide rod 611 are lifted, and the spring 610 is compressed. At this time, the blocking plate 67 temporarily no longer blocks the air inlet channel 5. When the incomplete gear 63 is separated from the driven gear 64, the baffle 69, the blocking plate 67 and the guide rod 611 are lowered under the rebounding action of the spring 610. At this time, the blocking plate 67 re-blocks the air inlet channel 5. Through the intermittent meshing of the complete gear and the driven gear 64, the function of intermittently blocking the air inlet channel 5 by the blocking plate 67 is realized.

[0058] When the blocking plate 67 does not block the air inlet channel 5, the airflow of the air inlet channel 5 drives the fully crushed edge material into the collection box 71. When the blocking plate 67 blocks the air inlet channel 5, the area of the air inlet channel 5 between the collection box 71 and the outer cylinder 1 is blocked at this time. At this time, the airflow of the air inlet channel 5 can only flow into the outer cylinder 1 through the leakage hole 9. The airflow passing through the leakage hole 9 will blow the insufficiently crushed edge material at the leakage hole 9 from bottom to top. The upwardly blown edge material contacts the second blade 49 for secondary crushing. After the upwardly blown edge material is crushed by the second blade 49, it is filtered by the annular filter plate 12. The insufficiently crushed edge material is blocked by the annular filter plate 12, while the fully crushed edge material enters the air inlet channel 5 through the feed pipe 11 and then enters the collection box 71. Through the intermittent blocking of the air inlet channel 5 by the blocking plate 67, the fully crushed edge material can enter the air inlet channel 5 through the leakage hole 9 and the annular filter plate 12 and the feed pipe 11, and then enter the collection box 71 as soon as possible, reducing the crushing time of the edge material and avoiding the over-crushing of part of the edge material, which affects the subsequent recycling and causes excessive dust during production.
