At the same time, collecting the crushed foam is cumbersome, and subsequent transportation and conveying are inconvenient. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6A waste recycling mechanism for foam processing includes a body 1, a crushing chamber 2 installed on the upper part of the body 1, a pair of cutting rollers 41 installed on the upper part of the crushing chamber 2, the cutting rollers 41 being driven by a drive motor 4 to achieve rotational crushing operation, a channel below the cutting rollers 41 narrowing inward, and a plurality of permanent magnet plates 51 being installed at an incline in the middle of the channel, the permanent magnet plates 51 being installed in a mounting frame 9 outside the crushing chamber 2 via a mounting plate 5;

[0024] The inner side of the mounting frame 9 is provided with multiple inclined slots 8, and the inclined slots 8 are connected to the inside of the crushing chamber 2. Each inclined slot 8 is filled with a permanent magnet plate 51, and one end of the permanent magnet plate 51 is installed on the outside of the mounting plate 5.

[0025] The bottom of the mounting frame 9 has a pair of slots, and a wedge-shaped limiting block 92 is rotatably installed in the slots via a pin. The vertical surface of the wedge-shaped limiting block 92 is in contact with the outer wall of the mounting frame 9, and the position of the mounting frame 9 is limited by the vertical surface.

[0026] Multiple rubber pads 91 are installed on the upper and lower ends of the inner wall of the mounting frame 9. When the mounting frame 9 is connected to the mounting plate 5, the mounting plate 5 and the rubber pads 91 are pressed into contact, and the rubber pads 91 provide friction to improve the tightness of the connection between the two.

[0027] A hydraulic cylinder 6 is installed on one side of the middle part of the machine body 1. The telescopic end of the hydraulic cylinder 6 is connected to the pressure block 61. The pressure block 61 and the interior of the machine body 1 form a pressing chamber 7. The upper part of the pressing chamber 7 is connected to the interior of the crushing chamber 2.

[0028] The upper part of the crushing chamber 2 is provided with a feed inlet 3.

[0029] A torsion spring 921 is installed at the rotatable connection between the wedge-shaped limiting block 92 and the mounting frame 9. When the wedge-shaped limiting block 92 rotates, the torsional force generated by the deformation of the torsion spring 921 drives the wedge-shaped limiting block 92 to rotate and reset.

[0030] The inclined surface of the wedge-shaped limiting block 92 faces outward, and the vertical surface faces the crushing chamber 2.

[0031] The outer side of the crushing chamber 2 is equipped with a drive motor 4. The output end of the drive motor 4 extends into the machine body 1 and drives a pair of cutting rollers 41 to rotate through a gear transmission group to achieve the crushing operation. The more detailed gear configuration, parameters and installation are common knowledge to those skilled in the art and will not be explained further.

[0032] The cutting roller 41 is equipped with cutting blades to cut and crush the material.

[0033] A maintenance plate is installed on the outside of the machine body 1. By opening the maintenance plate, the materials inside the pressing chamber 7 can be removed.

[0034] In this embodiment, foam waste enters through the feed inlet 3, and then the drive motor 4 is controlled by an external control mechanism to run. The cutting roller 41 rotates to cut and crush the waste. The crushed material falls downwards, and when the crushing is completed, all the crushed material falls into the pressing chamber 7 connected to the bottom of the crushing chamber 2. At this time, the hydraulic cylinder 6 extends and drives the pressing block 61 to push the crushed material, and the pressing chamber 7 presses the crushed material to facilitate material removal.

[0035] The crushing chamber 2 is equipped with a permanent magnet plate 51 in the middle. The permanent magnet plate 51 attracts the magnetic metal in the crushed material. After the crushing operation is completed, the wedge-shaped limiting block 92 at the bottom of the mounting frame 9 is pushed down and the mounting plate 5 is pulled out at the same time to drive the permanent magnet plate 51 away from the crushing chamber 2. The debris adsorbed on the permanent magnet plate 51 is scraped off by a plastic or copper hanging plate at an inclined angle to achieve maintenance.

[0036] During the installation of the permanent magnet plate 51, the permanent magnet plate 51 is inserted into the inclined slot 8, and gravity self-locking is achieved through the inclined slot 9. When the mounting plate 5 is connected to the mounting frame 9, the inclined surface of the wedge-shaped limiting block 92 is pressed against the outer wall of the mounting plate 5. Under the guidance of the inclined surface, the wedge-shaped limiting block 92 is deflected by the pressure. When the mounting plate 5 is fully assembled into the mounting frame 9, the spring 921 twists to drive the wedge-shaped limiting block 92 to reset and rotate, and limits the position of the wedge-shaped limiting block 92 by the vertical surface to the outer wall of the mounting plate 5.

[0037] The entire crushing process can not only effectively collect the magnetic metal in the crushed material, but also compress the crushed material into blocks through the hydraulic cylinder 6 and the pressure block 61 for easy collection. At the same time, in the later maintenance process, the self-locking mechanism of the inclined slot 8 and the wedge-shaped limit block 92 can realize the quick disassembly and assembly of the permanent magnet plate 51.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
