Description

Technical Field

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

[0002] With the widespread use of plastic products, the treatment of plastic waste has become an important issue for environmental protection and resource recycling. While existing plastic waste crushing devices can crush plastic waste, they have problems during operation. For example, many traditional crushing devices require a continuous flow of plastic waste into the crushing unit, resulting in an open-type design. Due to the lack of effective shielding structures, plastic waste easily splashes out of the feed inlet, causing not only material waste but also potential health hazards to operators. Summary of the Invention

[0003] The purpose of this invention is to provide a plastic waste crushing device to overcome the above-mentioned defects in the prior art.

[0004] A plastic waste crushing device includes a crusher body, a feeding box installed on the top of the crusher body, a feeding hopper provided at the feeding inlet on the side of the feeding box, and a shielding component provided between the feeding inlet and the feeding hopper to prevent material from splashing out during the crushing of plastic waste.

[0005] Preferably, the shielding assembly includes a fixed plate, a baffle, a torsion spring, and a stop rod. The baffle is rotatably connected to the lower end of the fixed plate via a rotating shaft. The torsion spring is sleeved on the rotating shaft and located in the mounting groove of the baffle. One end of the torsion spring is connected to the fixed plate, and the other end of the torsion spring is connected to the inner wall of the mounting groove. The stop rod is vertically disposed at the lower end of the baffle. The fixed plate is inserted into the limiting groove on the feed box and connected to the feed box.

[0006] Preferably, two torsion springs are provided and symmetrically arranged at both ends of the rotating shaft.

[0007] Preferably, the stop bar is made of rubber and has several of them, which are evenly distributed along the lower end of the baffle.

[0008] Preferably, the length of the stop bar extends below the feed end of the feed hopper.

[0009] Preferably, the fixing plate has an overall "L" shaped structure.

[0010] Preferably, the fixing plate is connected to the feed box by a number of bolts.

[0011] The beneficial effects achieved by this utility model are as follows:

[0012] This device, by incorporating a shielding component, effectively prevents plastic waste from splashing out of the crusher during the crushing process. Specifically, when plastic waste enters the feed hopper, the waste automatically pushes aside the baffle, allowing the material to smoothly enter the crushing section of the crusher. The baffle in the shielding component automatically resets under the action of a torsion spring, and, in conjunction with the feed hopper, prevents small particles of waste generated during crushing from splashing out of the feed inlet, thereby reducing material waste and avoiding dust pollution and potential injury to operators.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0021] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a plastic waste crushing device, including a crusher body 1, a feed box 2 installed on the top of the crusher body 1, and a feed hopper 3 provided at the feed inlet on the side of the feed box 2;

[0023] It should be noted that the feed box 2 is provided with a shielding component 4 between the feed inlet and the feed hopper 3 to prevent material from splashing out when the plastic waste is crushed. The shielding component 4 includes a fixed plate 41, a baffle 42, a torsion spring 44 and a baffle rod 45. The baffle 42 is rotatably connected to the lower end of the fixed plate 41 through a rotating shaft 43. Two torsion springs 44 are provided and sleeved on the rotating shaft 43 and located in the mounting groove 421 of the baffle 42. One end of the torsion spring 44 is connected to the fixed plate 41, and the other end of the torsion spring 44 is connected to the inner wall of the mounting groove 421.

[0024] In addition, the baffle 45 is vertically disposed at the lower end of the baffle 42. The baffle 45 is made of rubber and there are several of them, which are evenly distributed along the lower end of the baffle 42 to prevent the baffle 45 from contacting the feed hopper 3 and causing damage to the feed hopper 3. The length of the baffle 45 extends to the lower end of the feed hopper 3. The baffle 45 limits the rotation angle of the baffle 42 to prevent the baffle 42 from rotating excessively.

[0025] In addition, the fixing plate 41 has an overall "L" shaped structure and is inserted into the limiting groove on the feeding box 2 and connected to the feeding box 2 by several bolts, which makes it convenient to remove the fixing plate 41 from the feeding box 2 for maintenance and replacement of the baffle 42.

[0026] Detailed implementation methods and principles:

[0027] When using this device, the plastic waste to be crushed is poured into the feed box 2 of the crusher body 1 through the feed hopper 3;

[0028] As the plastic waste slides down, it will automatically push the baffle 42 inward, causing the rotating shaft 43 to rotate on the fixed plate 41. Based on the amount of plastic waste entering, the baffle 42 will adaptively adjust the size of the opening under the torque of the torsion spring 44 on the rotating shaft 43.

[0029] When plastic waste enters the crusher body 1, it is crushed by the crushing roller in the crusher body 1. Under the protection of the feed box 2 and the baffle 42, the crushed plastic waste is prevented from splashing out of the crusher body 1, causing waste and personnel injury. At the same time, the plastic waste can be continuously fed into the crusher body 1 for crushing.

[0030] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
