[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: This utility model provides a technical solution for a waste plastic recycling compaction device, such as... Figures 1-7As shown, the system includes a base support assembly 100, which includes a base 103, a mounting groove 104 formed on the top surface of the base 103, two fixing blocks 102 fixed to both sides of the base 103, two side baffles 101 fixed to the other two sides of the base 103, a support plate 107 connected between the two side baffles 101, a double pressure chamber mechanism 200 disposed on the top surface of the base 103, a compaction mechanism 400 fixed to the top surface of one fixing block 102, and a feeding assembly 300 fixed to the top surface of the other fixing block 102.

[0031] The dual-chamber mechanism 200 includes a motor 201 fixed inside the mounting groove 104, a connecting plate 202 connected to the top of the rotating motor 201, two sets of pressure box assemblies 204 fixed on both sides of the connecting plate 202, and a first guide rod 203 connected inside the connecting plate 202. The pressure box assembly 204 has a cavity structure with an open top surface. The two sets of pressure box assemblies 204 are rotated 180° about the top of the rotating motor 201. The pressure box assembly 204 is slidably attached to the top surface of the base 103. The two sets of pressure box assemblies 204 are driven to rotate by the motor 201 and are respectively located at the bottom of one side of the compaction mechanism 400 and the bottom of one side of the feeding assembly 300. The bottom of one side of the compaction mechanism 400 is a liftable structure and is used to insert into the cavity structure of the pressure box assembly 204.

[0032] By setting up a dual-chamber mechanism 200 with two sets of pressing chamber assemblies 204, it can be rotated to the bottom of the compaction mechanism 400 and the feeding assembly 300 respectively under the drive of the motor 201. The compaction mechanism 400 squeezes the waste plastic inside one set of pressing chamber assemblies 204, while the feeding assembly 300 introduces the next batch of waste plastic into the other set of pressing chamber assemblies 204. After the waste plastic is compacted, it can be directly rotated and continue to compact the waste plastic inside the other set of pressing chamber assemblies 204, thereby improving the working efficiency of compacting waste plastic.

[0033] like Figures 2-7 As shown, the pressing box assembly 204 includes a pressing box 205 fixed to the side wall of the connecting plate 202. The front wall of the pressing box 205 is provided with an outlet structure. A box door 206 is rotatably connected to the front wall of the pressing box 205. The box door 206 is used to fit and close the outlet structure of the pressing box 205. A locking component 207 is connected between the front wall of the box door 206 and the side wall of the pressing box 205. A pressing lock component 212 is fixed to the side wall of the pressing box 205. The pressing lock component 212 is provided at the bottom of the lifting structure of the compaction mechanism 400. A locking groove 105 is provided on the top surface of the base 103. The pressing lock component 212 is pushed and inserted into the locking groove 105 by the lifting structure of the compaction mechanism 400.

[0034] When the compaction mechanism 400 is pressed downward into the pressure box assembly 204 using its lifting structure, the locking component that pushes the side wall of the pressure box 205 is inserted into the locking groove 105 of the base 103, thereby positioning the pressure box 205, ensuring the accuracy of the compaction mechanism 400 pressing into the pressure box 205, and improving the stability of compacting the waste plastic inside the pressure box 205.

[0035] Furthermore, the locking component 207 includes a limiting block 208 fixed to the front wall of the box door 206, a locking head 210 inserted into the limiting block 208, a fixing bolt 209 that passes through and connects the limiting block 208 and the locking head 210, and a plug locking head 211 fixed to the side wall of the pressure box 205. The plug locking head 211 is moved through the locking head 210 to engage with the inside of the locking head 210.

[0036] When the box door 206 is used to close the outlet of the pressure box 205, the latch head 210 is moved inside the limit block 208 so that the locking head 211 is engaged inside the latch head 210. Then, the fixing bolt 209 is rotated to position and fix the latch head 210, thus ensuring the stability of the box door 206 closure.

[0037] Furthermore, the locking component 212 includes a limiting plate 217 fixed to the side wall of the pressing box 205, a locking plate 214 slidably inserted into the limiting plate 217, a first push plate 213 fixed to the top surface of the locking plate 214, a second guide rod 216 connected to the bottom surface of the first push plate 213, a first spring 215 sleeved on the outer wall of the second guide rod 216, the second guide rod 216 slidably connected to the inside of the limiting plate 217, the first spring 215 disposed between the bottom surface of the first push plate 213 and the top surface of the limiting plate 217, the locking plate 214 disposed at the top of the locking groove 105, and the first push plate 213 disposed at the bottom of the lifting structure of the compaction mechanism 400;

[0038] When the compaction mechanism 400 is lowered to press down the waste plastic, the first push plate 213 is simultaneously pressed down, causing the locking plate 214 to descend and insert into the locking groove 105, so that the pressing box 205 is positioned on the base 103. When the compaction mechanism 400 rises, the first spring 215 pushes the first push plate 213 to rise and reset, so that the pressing box 205 is unlocked from the base 103, so that the pressing box 205 can rotate to load materials, which improves the convenience of positioning operation.

[0039] Furthermore, the pressing box assembly 204 also includes a storage groove 219 that is connected through to the rear wall of the pressing box 205, a first hydraulic rod 218 fixed to the outer wall of the storage groove 219, and a pusher plate 220 connected to the telescopic end of the first hydraulic rod 218. The pusher plate 220 is inserted into the storage groove 219 and the inside of the pressing box 205, and the side of the pusher plate 220 away from the first hydraulic rod 218 is flush with the inner wall of the pressing box 205.

[0040] After the waste plastic is compacted, the first hydraulic pressure pushes the pusher plate 220 into the compaction box 205, pushing the compacted waste material out of the outlet of the compaction box 205, thereby improving the convenience of removing waste plastic.

[0041] like Figures 2-7 As shown, the compaction mechanism 400 includes a support plate 401 fixed to the top surface of the fixed block 102, a fixing plate 402 fixed to the top side wall of the support plate 401, a retaining plate 406 fixed between the side wall of the support plate 401 and the bottom surface of the fixing plate 402, a second hydraulic rod 403 disposed on the top surface of the fixing plate 402, a lifting plate 404 connected to the telescopic bottom end of the second hydraulic rod 403, a connecting rod 405 connected to the bottom surface of the lifting plate 404, a pressing plate 407 fixed to the bottom end of the connecting rod 405, a third guide rod 408 slidably connected inside the lifting plate 404, a second push plate 410 fixed to the bottom end of the third guide rod 408, a second spring 409 sleeved on the outer wall of the third guide rod 408, the second spring 409 disposed between the top surface of the second push plate 410 and the bottom surface of the lifting plate 404, the second push plate 410 disposed on the top of the first push plate 213, and the pressing plate 407 disposed on the top of the opening of the pressing box 205;

[0042] By pushing the lifting plate 404, the pressing plate 407 is inserted into the pressing box 205 to compact the waste plastic. During the descent of the lifting plate 404, the second push plate 410 comes into contact with the first push plate 213 and begins to compress the second spring 409 until the second spring 409 pushes the second push plate 410 with its elasticity. The second push plate 410 then pushes the first push plate 213 downward, inserting the locking plate 214 into the locking groove 105 for positioning.

[0043] Furthermore, the top surface of the base 103 is provided with a first ventilation hole 106, and there are two first ventilation holes 106 mirror images of the vertical center line of the base 103. The bottom surface of the pressure box 205 is provided with a second ventilation hole 221, and the second ventilation hole 221 and one of the first ventilation holes 106 are located on the same vertical center line.

[0044] The first ventilation hole 106 and the second ventilation hole 221 are connected, which can expel the internal air when compressing waste plastic, thereby facilitating further compaction of waste plastic.

[0045] Furthermore, the feeding assembly 300 includes a fixed straight ladder 302 fixed to the top surface of the fixed block 102, a feeding trough 301 inclinedly connected to the top surface of the fixed straight ladder 302, and a scraper 303 fixed to the side wall of the feeding trough 301. Two scraper 303 are mirror images of each other about the vertical center line of the feeding trough 301, and the bottom surface of the scraper 303 is attached to the top surface of the pressure box 205.

[0046] Waste plastic is fed into the pressing box 205 through the feeding trough 301 and the scraper 303. During the rotation of the pressing box 205, the scraper 303 scrapes away the waste plastic remaining on the top surface of the pressing box 205, thereby ensuring the stability of the subsequent compaction operation of the waste plastic by the rotation of the pressing box 205.

[0047] Specifically, waste plastic is fed into a pressing box 205 through the feeding trough 301, and then the motor 201 is started to drive the connecting plate 202 to rotate. During rotation, the scraper 303 scrapes and cleans the waste plastic remaining on the top of the pressing box 205 until the pressing box 205 containing waste plastic is rotated to the bottom of the pressing plate 407.

[0048] At this time, another batch of waste plastic can be added into another pressing box 205, and the second hydraulic rod 403 is activated to push the lifting plate 404 down. The second push plate 410 elastically pushes the locking plate 214 into the locking groove 105 on the base 103, ensuring that the pressing box 205 is stably positioned on the base 103. The lifting plate 404 continues to descend, and the pressing plate 407 enters the pressing box 205 to further compact the waste plastic. The compressed air is discharged through the second through hole and the inside of the second through hole. After the waste plastic is compacted, the lifting plate 404 is driven to rise, so that the pressing plate 407 is separated from the pressing box 205. The first spring 215 pushes the first push plate 213 to rise, and the locking plate 214 is separated from the base 103. Then the motor 201 is started to rotate another pressing box 205 to perform the compaction operation. The compacted pressing box 205 rotates to the bottom of the feeding trough 301.

[0049] Rotate the fixing bolt 209 to separate it from the locking head 210. Slide the locking head 210 inside the limiting block 208 to separate the locking head 210 from the locking head 211. Open the box door 206, start the first hydraulic rod 218 to push the pusher plate 220 into the pressure box 205 to push out the compacted waste plastic. Then close the box door 206 and continue to feed waste plastic into the pressure box 205.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
