Description

Technical Field

[0001] The invention relates to the technical field of crushing, in particular to a recycling device for notebook computer shell waste. Background Art

[0002] Laptop shells are made of recyclable plastic materials. In order to save resources and manufacturing costs, used laptop shells are usually recycled and then reprocessed into granular raw materials that meet the requirements of laptop shell materials. Currently, laptop shell waste is mainly processed into granular raw materials that meet the requirements through a crusher, but the cutting edge of the existing crusher is parallel to the horizontal plane. During crushing, the contact area between the cutter and the laptop shell is large, and the noise generated during crushing is loud.

[0003] To solve the above problems, a Chinese patent with publication number CN205815865U discloses a laptop shell crusher, including a body, a feed hopper hinged on the body, and a crushing knife arranged on the body, wherein the crushing knife includes a knife shaft that rotates with the body, a knife seat evenly arranged along the circumference of the knife shaft, a rotating knife plate fixedly connected to the knife seat by bolts, and a fixed knife plate horizontally installed on the body, wherein the cutting edge of the rotating knife plate intersects the horizontal plane at an acute angle, and the intersection angle is less than 30°. The cutting edge of the rotating knife plate of the crusher intersects the horizontal plane at an acute angle, so that when shearing the laptop shell, the shearing process is gradually completed, the shearing resistance is small, and the noise is low.

[0004] The following problems exist during the actual use of the above-mentioned crusher: after the laptop computer shell is crushed, the granular raw materials will fall directly into the receiving hopper for centralized collection, but the particle sizes of the granular raw materials in the receiving hopper are different, and the granular raw materials with qualified particle sizes need to be manually screened out and transferred to a designated place, while the granular raw materials with unqualified particle sizes need to be re-crushed, which is labor-intensive and cumbersome to operate. Summary of the invention

[0005] The present invention aims to provide a recycling device for laptop computer shell waste, so as to solve the problem that the particle sizes of the granular raw materials obtained by the existing pulverizer are different, manual screening is required, and the operation is complicated.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a recycling device for laptop computer shell waste, comprising a box body, with discharge ports on both sides of the box body; crushing mechanisms are provided on both sides of the box body, the crushing mechanisms include partitions and screening plates fixed to the box body, and the partitions and the side walls of the box body constitute a crushing chamber; two rotating shafts are rotatably connected to the partitions, and synchronous gears and crushing rollers are coaxially connected to the rotating shafts, and the two synchronous gears are meshed, and the crushing rollers are located above the screening plate, and a plurality of screening holes are equidistantly provided on the screening plate along the width direction of the screening plate; it also includes an introduction mechanism for introducing laptop computer shell waste into the two crushing chambers respectively, and a driving mechanism for driving the rotating shafts on the two partitions to rotate.

[0007] The principles and advantages of this solution are:

[0008] 1. This solution can grind the laptop computer shell waste through two rotating grinding rollers to obtain granular raw materials. Compared with the existing technology, when the particle size of the raw material particles is qualified, the granular raw materials fall to the bottom of the box through the screening holes and are discharged from the discharge port; when the particle size of the raw material particles is unqualified, they will continue to be crushed by the grinding rollers until the particle size of the raw material particles is qualified; therefore, this solution does not require manual screening, and can also make all raw material particles of qualified particle size, reducing manual labor intensity and making the operation easier.

[0009] 2. This solution can perform crushing in two crushing chambers at the same time, and can process more laptop computer shell waste in the same time, with higher work efficiency.

[0010] Furthermore, the introduction mechanism includes a fixed plate fixedly connected to the box body, a horizontal plate fixedly connected to the box body, and a feed port opened on the top of the box body on both sides of the middle plate.
