[0002] With the rapid development of the plastics industry and the continuous improvement of plastic performance, plastic parts are replacing traditional metal parts in different fields, thereby simplifying product structure and saving manufacturing costs. With the development of high technology and the growth of people's needs, plastic products are constantly being innovated. Plastic waste has become the fastest growing type of waste in the world, and plastic waste has considerable recycling value.

[0003] The recycling of plastic materials is particularly crucial, mainly employing mechanical processing including dismantling, crushing, and sorting. Therefore, crushing is an essential process in the recycling of plastic waste. Existing plastic crushers use crushing rollers to squeeze and break down the rubber into small particles. However, some rubber does not meet the required crushing grade and mixes with qualified rubber, making it difficult to separate and hindering subsequent processing of the crushed particles. To address this issue, we propose a plastic recycling crusher to solve the above problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a plastic recycling crusher, including a housing 1. A feed hopper 2 is fixedly connected to the top of the housing 1. The housing 1 is provided with a crushing chamber 101, a guiding chamber 102, and a recycling chamber 103 in sequence from top to bottom. A crushing roller 6 is rotatably installed in the crushing chamber 101. A screen frame 7 is movably provided at the bottom of the crushing roller 6. The screen frame 7 is movably provided in the recycling chamber 103. A transmission assembly 9 is fixedly connected to the bottom end of the screen frame 7. One end of a support rod 10 is fixedly connected to both ends of the transmission assembly 9. The other end of the support rod 10 is fixedly connected to the inner walls of both sides of the recycling chamber 103.

[0020] A guide plate 8 is fixed to the inner wall of the recycling chamber 103 on one side of the bottom of the screen frame 7. A feed hood 5 is fixed to the box body 1 on the side of the guide plate 8 away from the screen frame 7. One end of the feed hood 5 is fixedly connected to one end of the auger conveyor 3, and the other end of the auger conveyor 3 is fixedly connected to one end of the discharge pipe 4. The other end of the discharge pipe 4 is fixedly located on the top of the feed hopper 2.

[0021] The crushed plastic to be recycled is fed into the housing 1 through the feed hopper 2. The plastic is crushed by the crushing roller 6. The crushed particles are guided by the guide chamber 102 and fall onto the screen frame 7. A discharge port is opened on one side of the screen frame 7, located in the direction of the guide plate 8. The transmission component 9 works, driving the fixed screen frame 7 to move synchronously. The screen frame 7 then screens the crushed particles, and simultaneously realizes that the screen frame 7... Figure 2The structure shown swings back and forth, up and down, and while screening the particles, it also moves the particles inside the screen frame 7. When the unscreened particles move to the discharge port of the screen frame 7, they finally fall out of the discharge port. The falling particles are blocked by the guide plate 8 and enter the feed hood 5, and then enter the auger conveyor 3. Finally, the auger conveyor 3 lifts them to the discharge pipe 4 and discharges them into the feed hopper 2. The unscreened particles are then crushed again by the crushing roller 6.

[0022] Example 2

[0023] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, one end of several support columns 31 is fixedly connected to the outer wall of the auger conveyor 3, and the other end of the support columns 31 is fixedly connected to the outer wall of the box 1. The setting of the support columns 31 provides support for the fixed installation of the auger conveyor 3.

[0024] Specifically, the crushing chamber 101, the guiding chamber 102, and the recycling chamber 103 are interconnected. The recycling chamber 103 is hinged to a discharge box door at the end away from the guiding plate 8. The discharge box door facilitates the collection of qualified plastic crushed particles.

[0025] Specifically, the transmission assembly 9 includes a support housing 91, a transverse spring 92, a movable frame 93, a support slide rod 94, a vertical spring 95, a movable seat 96, a dual-output shaft motor 97, an eccentric block 98, a fixing plate 99, and a connecting frame 90. The ends of the support rod 10 are fixedly connected to the outer walls of both ends of the support housing 91. The movable frame 93 is slidably sleeved inside the support housing 91. One end of the transverse spring 92 is fixedly connected to both ends of the movable frame 93, and the other end of the transverse spring 92 is fixedly connected to the support housing 91. Movable seats 96 are slidably provided on the inner walls of both ends of the movable frame 93. A dual-output shaft motor 97 is fixedly installed in the movable seat 96. The output shafts on both sides of the dual-output shaft motor 97 are respectively fixedly connected to eccentric blocks 98. The eccentric blocks 98 are movably disposed in the support housing 91. Support slide rods 94 are slidably sleeved on both sides of the movable seat 96. The two ends of the support slide rods 94 are respectively fixedly connected to the inner walls of the movable frame 93. Several vertical springs 95 are movably provided on both sides of the movable seat 96. The vertical springs 95 are slidably sleeved on the support slide rods 94.

[0026] Furthermore, one end of the fixing plate 99 is fixedly connected to the bottom middle part of the movable seat 96, and the other end of the fixing plate 99 slides through the movable frame 93 and the support housing 91 respectively and is fixedly connected to the connecting frame 90. The two ends of the connecting frame 90 are fixedly connected to the bottom of the screen frame 7 respectively.

[0027] Furthermore, the connecting frame 90 has a U-shaped structure, the bottom of the supporting housing 91 has an opening 911, the fixed plate 99 is slidably disposed in the opening 911, and the movable frame 93 has a U-shaped structure.

[0028] When transmission component 9 operates, the dual-output shaft motor 97 of transmission component 9 is energized. The dual-output shaft motor 97 drives the fixed eccentric block 98 to rotate circumferentially. The eccentric block 98 drives the movable seat 96 to move. At the same time, with the elastic force of the transverse spring 92, the movable seat 96 moves as follows. Figure 3 As shown, the movable seat 96 swings left and right, which in turn drives the fixed plate 99 to move synchronously. The fixed plate 99 drives the fixed connecting frame 90 to move synchronously, and the connecting frame 90 drives the fixed screen frame 7 to move synchronously. The screen frame 7 then screens the crushed particles. While the movable seat 96 swings left and right, it is slidably connected to the support slide rod 94. At the same time, vertical springs 95 are provided at the top and bottom ends of the movable seat 96. The movable seat 96, in conjunction with the elastic force of the vertical springs 95, enables the movable seat 96 to move up and down, thereby enabling the screen frame 7 to move as shown. Figure 2 The structure shown swings back and forth, up and down, and while screening the particles, it also moves the particles inside the screen frame 7. When the unscreened particles move to the discharge port of the screen frame 7, they finally fall out of the discharge port. The falling particles are blocked by the guide plate 8 and enter the feed hood 5, and then enter the auger conveyor 3. Finally, the auger conveyor 3 lifts them to the discharge pipe 4 and discharges them into the feed hopper 2. The unscreened particles are then crushed again by the crushing roller 6.

[0029] Example 3

[0030] Reference Figure 1-3 This is the third embodiment of the present invention. Based on the previous two embodiments, in use, the plastic to be recycled and crushed is fed into the housing 1 through the feed hopper 2. The plastic is crushed by the crushing roller 6, and the crushed particles fall onto the screen frame 7 after being guided by the guide chamber 102. A discharge port is opened on one side of the screen frame 7, located in the direction of the guide plate 8. The transmission component 9 operates, and the dual-output shaft motor 97 of the transmission component 9 is energized. The dual-output shaft motor 97 drives the fixed eccentric block 98 to rotate circumferentially. The eccentric block 98 drives the movable seat 96 to move. Simultaneously, with the elastic force of the transverse spring 92, the movable seat 96 moves as follows. Figure 3 As shown, the movable seat 96 swings left and right, which in turn drives the fixed plate 99 to move synchronously. The fixed plate 99 drives the fixed connecting frame 90 to move synchronously, and the connecting frame 90 drives the fixed screen frame 7 to move synchronously. The screen frame 7 then screens the crushed particles. While the movable seat 96 swings left and right, it is slidably connected to the support slide rod 94. At the same time, vertical springs 95 are provided at the top and bottom ends of the movable seat 96. The movable seat 96, in conjunction with the elastic force of the vertical springs 95, enables the movable seat 96 to move up and down, thereby enabling the screen frame 7 to move as shown. Figure 2The structure shown swings back and forth, up and down, and while screening the particles, it also moves the particles inside the screen frame 7. When the unscreened particles move to the discharge port of the screen frame 7, they finally fall out of the discharge port. The falling particles are blocked by the guide plate 8 and enter the feed hood 5, and then enter the auger conveyor 3. Finally, the auger conveyor 3 lifts them to the discharge pipe 4 and discharges them into the feed hopper 2. The unscreened particles are then crushed again by the crushing roller 6.
