Description

Technical Field

[0001] This utility model belongs to the field of PP sheet cutting technology, specifically relating to a PP sheet cutting waste recycling device. Background Technology

[0002] PP sheet is a semi-crystalline material. It is harder and has a higher melting point than PE. Both homopolymer and copolymer PP materials have excellent resistance to moisture absorption, acid and alkali corrosion, and solvents, but they are not resistant to aromatic hydrocarbon solvents, chlorinated hydrocarbon solvents, etc.

[0003] In the existing technology, when PP boards are cut on a workbench, a certain amount of waste is generated. This waste is scattered on the surface of the workbench, making it inconvenient for users to clean the surface of the workbench and to recycle the PP board waste scattered on the table. This makes the recycling and reuse of PP board waste inconvenient and unfavorable to use.

[0004] Therefore, there is a need for a PP sheet cutting waste recycling device to solve the problem that existing technologies cause PP sheet cutting waste to be scattered on the surface of the workbench, making it inconvenient for users to clean the workbench surface and recycle the scattered PP sheet waste. Utility Model Content

[0005] The purpose of this invention is to provide a PP sheet cutting waste recycling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a PP sheet cutting waste recycling device, comprising a workbench, a collection box disposed at the bottom of the workbench, a first table board fixed to both sides of the inner cavity of the workbench, a second table board disposed at the middle position of the two first table boards, and a cleaning and collection mechanism for recycling PP waste.

[0007] The cleaning and collection mechanism includes a scraping component and a flipping component;

[0008] The flipping assembly includes a movable shaft fixed at the middle position of the second tabletop, a positioning and sealing component acting on the movable shaft, multiple oscillating motors fixed at the bottom of the movable shaft, and rubber strips fixed on both sides of the second tabletop. One end of the movable shaft is rotatably connected to the inner wall of the worktable, and the other end of the movable shaft passes through the worktable and extends to one end of the worktable.

[0009] It should be noted in the solution that the positioning and sealing component includes an inner compartment formed on one side surface of the first tabletop, a plurality of spring telescopic rods uniformly fixed in the inner cavity of the inner compartment, a locking block fixed to one side of the spring telescopic rod, and a limiting groove formed on both sides of the second tabletop at the bottom position of the rubber strip.

[0010] It is further worth noting that the scraping assembly includes two fixing blocks fixed to one end surface of the workbench, a first threaded rod rotatably connected to the middle position of the two fixing blocks, a threaded sleeve threaded to both sides of the outer circumferential surface of the first threaded rod, a scraper fitted to the top of the first tabletop, a connecting strip fixed to the top of the threaded sleeve, and a guide component acting on the threaded sleeve.

[0011] Furthermore, it should be noted that one end of the connecting strip is fixed to the surface of the adjacent scraper, and the inner surface of the scraper is V-shaped.

[0012] In a preferred embodiment, the guide component includes an abutment groove formed on the surface of the threaded sleeve and a limiting strip inserted through the middle of the two abutment grooves, one end of the limiting strip being fixed to the surface of the workbench.

[0013] In a preferred embodiment, the cleaning and collecting mechanism further includes a limiting component for defining the movable shaft. The limiting component includes two support blocks fixed to the other end of the workbench, a second threaded rod rotatably connected to the middle position of the support blocks, a rack threaded to the outer circumferential surface of the second threaded rod, a circular gear meshing at the bottom of the rack, a support rod fixed at the middle position of the support blocks at one end of the second threaded rod, a positioning sleeve fixed at one end of the rack, and two positioning rings fixed to the outer circumferential surface of the support rod.

[0014] In a preferred embodiment, the middle position of the spherical gear is fixed to the outer circumferential surface of the movable shaft, and the positioning sleeve and the support rod are slidably connected.

[0015] Compared with the prior art, the PP sheet cutting waste recycling equipment provided by this utility model has at least the following beneficial effects:

[0016] (1) By rotating the first threaded rod, the scraper can scrape off the PP sheet waste attached to the surface of the first table and move it to the top of the second table. Then, by rotating the second table, the waste accumulated on the surface of the second table can slide from the surface of the second table into the inside of the collection box. Under the action of the oscillating motor, the waste accumulated on the surface of the second table can be fully dropped into the inside of the collection box. This makes it convenient for users to quickly clean and recycle the waste attached to the surface of the first and second tables, thereby improving the effect of PP waste recycling and improving the applicability of the device.

[0017] (2) By rotating, the rack can move in the horizontal direction, so that the movable shaft can rotate under the meshing action between the rack and the movable shaft, thereby causing the second table to change angle. Since the two positioning rings can position the positioning sleeve, the flip angle of the second table can be limited, so that the user can flip the second table to ninety degrees, thereby further improving the applicability of the device.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model provides a PP sheet cutting waste recycling device, including a workbench 1, a collection box 2 set at the bottom of the workbench 1, a first table board 3 fixed on both sides of the inner cavity of the workbench 1, a second table board 4 set at the middle position of the two first table boards 3, and a cleaning and collection mechanism for recycling PP waste.

[0028] The cleaning and collection mechanism includes a scraping component and a flipping component;

[0029] After the PP sheet cutting operation is completed at the workbench 1, a certain amount of PP sheet waste will remain on the surface of the first table 3 and the second table 4. The scraping component can scrape off the waste material attached to the surface of the first table 3 and transport it to the surface of the second table 4. Then, under the action of the flipping component, the second table 4 can be folded over, and under the action of gravity, the waste material attached to the surface of the second table 4 can fall into the inside of the collection box 2 to realize the waste recycling operation.

[0030] Please see Figure 1-6 The flipping assembly includes a movable shaft 5 that passes through and is fixed in the middle of the second table 4, a positioning and sealing component that acts on the movable shaft 5, multiple oscillating motors 6 fixed to the bottom of the movable shaft 5, and rubber strips 11 fixed to both sides of the second table 4. One end of the movable shaft 5 is rotatably connected to the inner wall of the worktable 1, and the other end of the movable shaft 5 passes through the worktable 1 and extends to one end of the worktable 1.

[0031] The second table plate 4 can be rotated by rotating the oscillating motor 6. Since the rubber strip 11 is an elastic component, the second table plate 4 will not get stuck during rotation. When the second table plate 4 is folded into a vertical state, the PP waste material attached to the top surface of the second table plate 4 can fall from the gap between the second table plate 4 and the first table plate 3 into the collection box 2 for recycling. During this process, the oscillating motor 6 is activated to make the second table plate 4 vibrate, thereby helping the waste material attached to the surface of the second table plate 4 to be fully separated from the second table plate 4, thus preventing the waste material from still being attached to the surface of the second table plate 4 after it is flipped. When the second table plate 4 is rotated in the opposite direction to return to a horizontal state, the positioning and sealing component can position the second table plate 4 and, together with the rubber strip 11, seal the gaps between the two sides of the second table plate 4 and the first table plate 3.

[0032] Please see Figure 1-6 The positioning and sealing components include an inner chamber 7 opened on one side surface of the first table 3, a plurality of spring telescopic rods 8 evenly fixed in the inner cavity of the inner chamber 7, a locking block 9 fixed on one side of the spring telescopic rods 8, and a limiting groove 10 opened on both sides of the second table 4 at the bottom position of the rubber strip 11.

[0033] When the second tabletop 4 flips from a horizontal position to a vertical position, the spring telescopic rod 8 retracts due to the contact between the inner cavity of the limiting groove 10 and the locking block 9, thereby releasing the restriction on the second tabletop 4. When the second tabletop 4 flips from a vertical position to a horizontal position, the spring telescopic rod 8 retracts again due to the contact between the second tabletop 4 and the locking block 9. When the limiting groove 10 moves to a position that is on the same horizontal line as the adjacent locking block 9, the spring telescopic rod 8 can be inserted into the interior of the adjacent limiting groove 10 under the action of the spring rebound force, thereby positioning the second tabletop 4 and sealing the gap between the two sides of the second tabletop 4 and the first tabletop 3 with the rubber strip 11.

[0034] Please see Figure 1-6 The scraping assembly includes two fixing blocks 13 fixed to one end surface of the workbench 1, a first threaded rod 14 rotatably connected to the middle position of the two fixing blocks 13, a threaded sleeve 15 threadedly connected to both sides of the outer peripheral surface of the first threaded rod 14, a scraper 12 fitted to the top of the first table board 3, a connecting strip 16 fixed to the top of the threaded sleeve 15, and a guide component acting on the threaded sleeve 15. One end of the connecting strip 16 is fixed to the surface of the adjacent scraper 12, and the inner surface of the scraper 12 is V-shaped.

[0035] Because the guide component can limit the movement of the threaded sleeve 15 to the horizontal direction, and the external thread structures on both sides of the outer circumference of the first threaded rod 14 are arranged in opposite directions, when the first threaded rod 14 is rotated, it can move towards each other under the cooperation of the thread structure between the first threaded rod 14 and the threaded sleeve 15. Thus, the scraper 12 starts to move towards the second table 4 from the position on the top of the first table 3 away from the second table 4. Thus, the PP waste attached to the top surface of the first table 3 can be scraped off under the shape of the scraper 12 until the PP waste accumulates on the surface of the second table 4. Then, the first threaded rod 14 is rotated in the opposite direction so that the scraper 12 can be reset to the position on the top of the first table 3 away from the second table 4.

[0036] Please see Figure 1-6 The guide component includes an abutment groove 17 formed on the surface of the threaded sleeve 15 and a limiting strip 18 inserted through the middle position of the two abutment grooves 17. One end of the limiting strip 18 is fixed to the surface of the worktable 1.

[0037] Because the surface of the limiting strip 18 and the inner cavity surface of the contact groove 17 are in contact, the threaded sleeve 15 cannot change angle. As a result, the threaded sleeve 15 can only slide in the horizontal direction under the drive of the thread structure of the first threaded rod 14, thus limiting the threaded sleeve 15.

[0038] Example 2

[0039] Therefore, referring to Figure 1-6 As shown, the cleaning and collection mechanism also includes a limiting component for limiting the movable shaft 5. The limiting component includes two support blocks 19 fixed to the other end of the workbench 1, a second threaded rod 20 rotatably connected to the middle position of the support block 19, a rack 22 threaded to the outer circumferential surface of the second threaded rod 20, a spur gear 21 meshing with the bottom of the rack 22, a support rod 24 fixed at the middle position of the support block 19 at one end of the second threaded rod 20, a positioning sleeve 23 fixed at one end of the rack 22, and two positioning rings 25 fixed to the outer circumferential surface of the support rod 24. The middle position of the spur gear 21 is fixed to the outer circumferential surface of the movable shaft 5, and the positioning sleeve 23 and the support rod 24 are slidably connected.

[0040] Since the positioning sleeve 23 can only slide on the outer circumferential surface of the support rod 24, it can limit the movement trajectory of the rack 22. When the second threaded rod 20 is rotated, it can move horizontally under the action of the threaded structure between the rack 22 and the second threaded rod 20, so that the rack 22 can mesh with the spur gear 21. This allows the movable shaft 5 to drive the second table 4 to flip. Since the rack 22 is driven by the second threaded rod 20, it is easy for the user to control the rotation amplitude of the movable shaft 5. The displacement range of the positioning sleeve 23 can be limited by the two positioning rings 25. The range in which the two positioning sleeves 23 can slide between the two positioning rings 25 is just enough to allow the second table 4 to flip 90 degrees when the rack 22 meshes with the spur gear 21, so that the waste attached to the surface of the second table 4 can slide into the inside of the collection box 2.
