Description

Technical Field

[0001] This utility model relates to the field of waste recycling equipment, specifically a waste plastic processing, recycling and regeneration device. Background Technology

[0002] The core process of a PVC window and door shredder shredding door and window frames is broken down as follows: The entire frame (including steel reinforcement, aluminum pulleys, and hardware) is fed directly into the hopper without pre-removing the glass or sealing strips. The hopper is double-layered with sound insulation to reduce impact noise. Two opposing rotating shafts are equipped with 30-40 claw-shaped moving blades, each 60mm thick with a "hawk's beak" shaped cutting edge. When the frame enters the blade box, the claws first grip the PVC shell into the blade seam, creating the first longitudinal tear. Next, the back of the blade and the opposing blade form a shearing gap of 0.3–0.5 mm, cutting the steel liner into 3–5 cm segments like scissors. The fixed blade (middle comb plate) below the cutter roller performs a "secondary shearing" on the large pieces that are not broken, ensuring that the plastic and the steel liner are crushed synchronously. The crushed mixture falls onto the wide magnetic separator belt, and the iron / steel segments are attracted away under the 3000 Gs magnetic field. The PVC granules continue to fall onto the discharge belt and can be directly sent to the granulator. After magnetic separation, the iron content of the PVC is ≤0.5%.

[0003] When a door frame is fed into a shredder for crushing, the two opposing rotating spindles drive the claw-shaped moving blades to tear the bottom of the door frame first. During the tearing process, the other end of the door or window will swing. If a worker is not careful and gets too close, the door frame may hit the worker's body, resulting in injury. Therefore, a waste plastic processing, recycling and regeneration device is proposed to address the above problem. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a waste plastic processing, recycling and regeneration device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a waste plastic processing, recycling and regeneration device, including a shredder, a protective frame rotatably connected to the upper feed frame of the shredder, a positioning block engaged with the front side of the protective frame, the end of the positioning block fixedly connected to the frame of the feed frame of the shredder, a power rod fixedly connected to the front frame of the shredder, a pressure member fixedly connected to the end of the power rod, an insertion hole opened on the side of the pressure member, and an anti-collision pad fixedly connected to the side of the feed frame of the shredder;

[0006] Preferably, the protective frame includes: a limiting post and a gear post. One end of the protective frame is fixedly connected to the post body of the limiting post, and the end of the limiting post is rotatably connected to the rear side of the shredder feed frame. The other end of the protective frame is fixedly connected to the post body of the gear post, and the end of the gear post is rotatably connected to the front side of the shredder feed frame. The gear post is meshed with the positioning block.

[0007] Preferably, the positioning block includes: a spring, a guide post, and a drive tooth plate. The end of the positioning block is fixedly connected to the end of the guide post. The outer wall of the guide post is fitted with the spring, and the column body of the guide post is slidably connected to the hole in the middle of the drive tooth plate.

[0008] Preferably, the drive tooth plate includes: a pin, an L-shaped groove, and a pull column. The end of the drive tooth plate is slidably connected to the pin, the frame of the drive tooth plate has an L-shaped groove, the column of the pin is fixedly connected to the end of the pull column, and the pull column is slidably connected to the L-shaped groove.

[0009] Preferably, the power rod includes: a ring plate, a pull handle, and a positioning rod. The column of the power rod is fixedly connected to the ring plate, the end of the power rod is fixedly connected to the end of the pull handle, the column of the power rod is slidably connected to one end of the positioning rod, and the other end of the positioning rod is fixedly connected to the frame of the shredder.

[0010] Preferably, the positioning rod includes: a second spring and a blocking block.

[0011] The advantages of this utility model are:

[0012] 1. This utility model drives the gear column to rotate by driving the gear plate, and the gear column drives the protective frame to rotate. In this way, the protective frames on both sides rotate synchronously. When the shredder continues to shred the lower part of the door frame, the upper part of the door frame will be restricted by the protective frames on both sides to prevent the door frame from shaking too much. This can prevent workers from being hit by the violently shaking door frame.

[0013] 2. This utility model, through the engagement of the insertion hole and the insertion post, can self-lock after the protective frame has rotated to the correct position, preventing the protective frame from becoming loose and wobbly during the protection process. At the same time, by pulling the post between the two slots of the L-shaped groove, the movement of the insertion post from the insertion hole can be determined, so that the spring two drives the pressure member to reset. This can also be converted into whether the insertion post can be blocked by the pressure member, so that the insertion post will not retract into the hole of the drive tooth plate. When the pull handle is blocked by the blocking block, even if the door frame presses on the pressure member during the deployment process, the pressure member will not trigger the rotation of the protective frame.

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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a waste plastic processing, recycling and regeneration device, including a shredder 1. A protective frame 2 is rotatably connected to the upper feed frame of the shredder 1. A positioning block 3 is engaged with the front side of the protective frame 2. The end of the positioning block 3 is fixedly connected to the frame of the feed frame of the shredder 1. A power rod 7 is fixedly connected to the front frame of the shredder 1. A pressure member 5 is fixedly connected to the end of the power rod 7. An insertion hole 51 is opened on the side of the pressure member 5. An anti-collision pad 6 is fixedly connected to the side of the feed frame of the shredder 1.

[0024] The protective frame 2 includes: a limiting post 20 and a gear post 21. One end of the protective frame 2 is fixedly connected to the post body of the limiting post 20, and the end of the limiting post 20 is rotatably connected to the rear side of the feed frame of the shredder 1. The other end of the protective frame 2 is fixedly connected to the post body of the gear post 21, and the end of the gear post 21 is rotatably connected to the front side of the feed frame of the shredder 1. The gear teeth of the gear post 21 are meshed with the positioning block 3.

[0025] The positioning block 3 includes: a spring 31, a guide post 32, and a drive tooth plate 33. The end of the positioning block 3 is fixedly connected to the end of the guide post 32. The outer wall of the guide post 32 is fitted with the spring 31. The column of the guide post 32 is slidably connected to the hole in the middle of the drive tooth plate 33.

[0026] The drive tooth plate 33 includes: a post 331, an L-shaped groove 332, and a pull post 333. The end of the drive tooth plate 33 is slidably connected to the post 331. The frame of the drive tooth plate 33 has an L-shaped groove 332. The post body of the post 331 is fixedly connected to the end of the pull post 333. The pull post 333 is slidably connected to the L-shaped groove 332.

[0027] The power rod 7 includes: a ring plate 71, a pull handle 72, and a positioning rod 73. The column of the power rod 7 is fixedly connected to the ring plate 71, the end of the power rod 7 is fixedly connected to the end of the pull handle 72, the column of the power rod 7 is slidably connected to one end of the positioning rod 73, and the other end of the positioning rod 73 is fixedly connected to the frame of the shredder 1.

[0028] The positioning rod 73 includes: a second spring 731 and a blocking block 732. The frame of the positioning rod 73 is fixedly connected to the end of the blocking block 732, and the end of the positioning rod 73 is fixedly connected to the end of the second spring 731. The second spring 731 is sleeved on the outer wall of the connecting power rod 7.

[0029] Working principle: After the door frame is put into the feed box at the top of the shredder 1, first turn the handle 72 by hand to prevent the bottom of the handle 72 from being blocked by the blocking block 732. Then pull the handle 72 down forcefully. This will cause the handle 72 to drive the power rod 7 to move down, and the ring plate 71 will move down simultaneously. The ring plate 71 will compress the second spring 731. At the same time, the power rod 7 will drive the pressure member 5 to move down, and the inclined edge of the side of the pressure member 5 will squeeze the insert 331. The insert 331 will squeeze the drive tooth plate 33 to drive the gear column 21 to rotate. When the drive tooth plate 33 moves, it will squeeze the first spring 31. The gear column 21 will drive the protective frame 2 to rotate. When the insertion hole 51 is aligned with the insertion post 331, the insertion post 331 will be inserted into the insertion hole 51. The pressure component 5 drives the drive gear plate 33 to slide under the restriction of the guide post 32. The drive gear plate 33 will drive the gear column 21 to rotate. The gear column 21 drives the protective frame 2 to rotate 90 degrees. In this way, the protective frames 2 on both sides rotate synchronously. When the shredder 1 continues to shred the lower part of the door frame, the upper part of the door frame will be restricted by the protective frames 2 on both sides to prevent the door frame from shaking too much. This will prevent workers from being hit by the violently shaking door frame.

[0030] By engaging the insertion hole 51 with the insertion post 331, the protective frame 2 can be self-locked after rotating into place, preventing the protective frame 2 from becoming loose and wobbly during the protection process. At the same time, by pulling the pull post 333 between the two slots of the L-shaped groove 332, the state of the insertion post 331 can be switched, which determines whether the insertion post 331 moves from the insertion hole 51, so that the spring 2 731 drives the pressure member 5 to reset. This can also be converted into whether the insertion post 331 can be blocked by the pressure member 5, so that the insertion post 331 will not retract into the hole of the drive tooth plate 33. When the pull handle 72 is blocked by the blocking block 732, even if the door frame presses on the pressure member 5 during the deployment process, the pressure member 5 will not trigger the rotation of the protective frame 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
