DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figure 1 to Figure 3 ,in Figure 1 is a front view of a first embodiment of the present invention; Figure 2 The present invention Figure 1 Sectional view along line AA; Figure 3 The present invention Figure 2 Cross-sectional view along line BB.

[0027] The present invention provides a plastic recycling, processing and crushing device for the production of walking wheels, comprising a shell 101, a box body 102 and an auxiliary mechanism, wherein a spiral blade 103 is arranged in the shell body 101, and the spiral blade 103 is driven by a servo motor 104, a feeding end 105 is arranged at the lower part of the shell body 101, a discharging end 106 is arranged at the upper part of the shell body 101, a crushing mechanism 107 is arranged at the upper part of the box body 102, a sieve plate 108 is slidably arranged at the lower part of the box body 102, a plurality of slide bars 109 are arranged below the sieve plate 108, and the plurality of slide bars 109 pass through the inner bottom of the box body 102, a discharging through hole 110 is arranged at the front end surface of the box body 102, a circulation through hole 111 and an auxiliary through hole 112 are arranged at the rear end surface of the box body 102, a feeding through hole 113 is arranged above the box body 102, and the shell 101 and the The box body 102 is fixedly connected and located at the rear end face of the box body 102, and the feed end 105 is connected to the circulation through hole 111, and the discharge end 106 is connected to the auxiliary through hole 112. By passing the plastic products into the box body 102 through the feed through hole 113 arranged above the box body 102, after the plastic products enter the box body 102, they are first crushed by the crushing mechanism 107 above, and the crushed plastic products are screened by the sieve plate 108 arranged at the lower part of the box body 102. The sieve plate 108 can easily screen out larger plastic products and transport them to the outer shell 101 under the action of the auxiliary mechanism, and then the screened plastic products are re-conveyed to the crushing mechanism 107 through the spiral blade 103 for secondary crushing, while the smaller plastic products are discharged through the discharge through hole 110.

[0028] According to the present specific embodiment, the auxiliary mechanism includes two auxiliary rods 114, two brackets 115 and a dual-axis motor 116. The auxiliary rod 114 is sleeved with a spring 117. A contact block 118 is arranged below the auxiliary rod 114. Cams 119 are arranged at both output ends of the dual-axis motor 116, and the cams 119 are adapted to the contact blocks 118. The two auxiliary rods 114 are respectively fixedly connected to the sieve plate 108 and are located on both sides of the sieve plate 108. The spring 117 is welded between the sieve plate 108 and the box body 102. The two auxiliary rods 114 are also respectively slidably connected to the box body 102 and pass through the inner bottom of the box body 102, and are also located between the corresponding two sliding rods 109. The two brackets 115 are respectively fixedly connected to the box body 102 and are located below the box body 102. The dual-axis motor 116 is connected to the box body 1 02 is fixedly connected and is located below the box body 102, and is also located between the two brackets 115. The two cams 119 are respectively located directly below the corresponding contact blocks 118, and the two output ends of the dual-axis motor 116 also respectively penetrate the corresponding brackets 115. The two cams 119 are slowly driven to rotate by the dual-axis motor 116. The cams 119 interact with the contact blocks 118, so that the contact blocks 118 and the auxiliary rods 114 and the screen plates 108 connected thereto generate upward movement, and then move downward instantly under the action of the springs 117, thereby generating vibration. When the cams 119 continue to rotate, the screen plates 108 can continue to reciprocate up and down. This vibration helps plastic products of different sizes on the screen plates 108 to enter the housing 101 faster, and the vibration can effectively prevent blockage and improve screening efficiency.

[0029] Among them, a limiting ring 120 is arranged on the slide bar 109, an anti-slip ring 121 is arranged below the slide bar 109, and the limiting ring 120 is abutted against the inner bottom of the box body 102. The limiting ring 120 can be used to limit the downward movement distance of the slide bar 109, thereby avoiding the collision between the sieve plate 108 and the lower components, and the anti-slip ring 121 can be used to limit the upward movement distance of the slide bar 109, thereby avoiding the collision between the sieve plate 108 and the upper components.

[0030] Secondly, the sieve plate 108 is inclined, and the lowest point of the sieve plate 108 is located at the circulation through hole 111. By arranging the lowest point of the sieve plate 108 toward the circulation through hole 111, it is convenient to introduce larger plastic products into the housing 101.

[0031] When using the plastic recycling and crushing device for the production of walking wheels of this embodiment, by starting the dual-axis motor 116, the dual-axis motor 116 slowly drives the two cams 119 to rotate, and the cam 119 pushes up the contact block 118. After the contact block 118 is pushed up, it will drive the auxiliary rod 114 to move upward, so that the screen plate 108 moves upward. At this time, the spring 117 is in a stretched state. When the cam 119 rotates to the end away from the contact block 118, the screen plate 108 is moved upward under the action of the spring 117. The cam 119 is continuously rotated and the screen plate 108 continuously reciprocates up and down, causing the plastic products to bounce up and vibrate. Furthermore, since the screen plate 108 is inclined, the plastic products can quickly enter the shell 101. This effectively solves the technical problem that the screen plate 108 is fixed, and the larger plastic products after crushing can only slowly enter the shell 101 under the action of gravity and the inclined screen plate 108, which easily leads to excessive accumulation of plastic products on the screen plate 108 and affects the discharging effect.
