The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figures 1 to 6 , is a plastic waste recycling and pulverizing device according to an embodiment of the present invention, comprising a supporting component 10, a pulverizing component 20 installed at one end of the supporting component 10, and a screening component 30 installed at the other end of the supporting component 10.

[0031] The bearing assembly 10 includes a bearing frame 11 , blanking plates 12 installed on opposite sides of one end of the bearing frame 11 , rollers 13 rotatably installed on opposite ends of the inner wall of each blanking plate 12 , and an arc-shaped guide plate 14 installed on one end of the blanking plate 12 .

[0032] Among them, Figure 3 As shown, the two blanking plates 12 are spaced apart and are arranged roughly in a "V" shape to facilitate blanking.

[0033] In this embodiment, the axial direction of the roller 13 is consistent with the length direction of the blanking plate 12 .

[0034] The crushing assembly 20 includes a crushing box 21 installed on one end of the carrier 11 away from the unloading plate 12, two crushing roller groups 22 installed inside the crushing box 21, an inlet hopper 23 installed on the top of the crushing box 21, and a discharge hopper 24 installed on the bottom of the crushing box 21; the end of the discharge hopper 24 is used to connect the screening assembly 30.

[0035] One crushing roller set 22 is located at the upper part of the crushing box 21 , and the other crushing roller set 22 is located at the lower part of the crushing box 21 .

[0036] Specifically, the crushing roller set 22 includes a fixed crushing roller 221 installed on one side of the crushing box 21, a movable crushing roller 222 slidably installed on the other side of the crushing box 21, a slider 223 coaxially sleeved on opposite ends of the movable crushing roller 222, an adjusting screw 224 rotatably connected to the slider 223, and a nut sleeve 225 installed on the outside of the crushing box 21 corresponding to one side of the movable crushing roller 222; the nut sleeve 225 is matched and connected to the adjusting screw 224. The slider 223 is slidably connected to the crushing box 21 through a guide rail pair (not shown), and the rotating adjusting screw 224 can drive the slider 223 to slide, thereby adjusting the gap between the movable crushing roller 222 and the fixed crushing roller 221 to adjust the crushed particle size.

[0037] like Figure 4 As shown, the fixed crushing roller 221 and the movable crushing roller 222 are synchronously rotated by a gear set, and the rotation direction of the fixed crushing roller 221 is opposite to the rotation direction of the movable crushing roller 222. The gear set is a common design of a mechanical transmission structure, and will not be described in detail here.

[0038] The gap between the fixed crushing roller 221 and the movable crushing roller 222 located at the upper part of the crushing box 21 is larger than the gap between the fixed crushing roller 221 and the movable crushing roller 222 located at the lower part of the crushing box 21. Based on this design, the plastic waste can be crushed for the second time to improve the crushing effect, and then the crushed materials fall into the screening component 30 along the discharge hopper 24.

[0039] The screening assembly 30 includes a roller 31 rotatably connected to the carrier frame 11, a driven gear 32 coaxially sleeved on the outer periphery of the roller 31 at one end close to the crushing box 21, a motor 33 installed below the crushing box 21, a driving gear 34 coaxially connected to the rotor of the motor 33, and a chain 35 sleeved between the driving gear 34 and the driven gear 32; the motor 33 can drive the roller 31 to rotate.

[0040] Specifically, the end of the discharge hopper 24 extends into the interior of the drum 31 , and annular channel steels 36 are respectively sleeved on the outer circumferences of the opposite ends of the drum 31 . The annular channel steels 35 are used to accommodate the rollers 13 to achieve a sliding connection between the drum 31 and the carrier frame 11 .

[0041] In this embodiment, the axis of the roller 31 is inclined to the horizontal plane, and the end of the roller 31 corresponds to the arc-shaped guide plate 14. The roller 31 is evenly spaced with a plurality of sieve holes 310, and the roller 31 is located above the two unloading plates 12. The qualified scraps passing through the sieve holes 310 will pass through the two unloading plates 12 and fall into the qualified product collection container. The unqualified scraps that have not passed through the sieve holes 310 will fall into the unqualified collection container along the roller 31 and the arc-shaped guide plate 14, and the unqualified scraps in the unqualified collection container will be poured into the hopper 23 for another crushing, ensuring the crushing particle size and improving the crushing effect.

[0042] The above-mentioned plastic waste recycling and crushing device has a simple structure and is easy to use. The crushing roller group 22 includes a fixed crushing roller 221 and a slidable movable crushing roller 222. The gap between the fixed crushing roller 221 and the movable crushing roller 222 can be adjusted. In conjunction with the screening of the roller 31, secondary crushing can be performed to ensure the crushing particle size and improve the crushing effect.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
