Description

Technical Field

[0001] This application belongs to the field of crusher technology, and in particular relates to a crusher for magnetic steel billets. Background Technology

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are tetragonal crystals formed by neodymium, iron, and boron. During the production of magnets, a lot of blanks (i.e. waste) are generated, which need to be crushed and processed uniformly.

[0003] However, different crushing fineness may require multiple random cuts to achieve, and the crushing gap cannot be adjusted to obtain the required fineness after multiple crushings on the same crusher. This needs to be improved. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a crusher for magnetic steel billets, which can achieve the required fineness after multiple crushings by adjusting the crushing gap.

[0005] This application provides a crusher for magnetic steel billets, comprising: frame; The fixed roller is movably mounted on the frame via bearings. The movable roller body is provided with a bearing seat that is movably connected to the frame, and the movable roller body and the bearing seat are movably connected by a bearing; The first drive cylinder body is installed between the bearing housing and the frame; The feeding mechanism includes a first flexible conveyor belt and a second flexible conveyor belt; A conveying channel is provided between the first flexible conveyor belt and the second flexible conveyor belt, and a crushing gap is provided between the fixed roller and the movable roller. The conveying channel is located above the crushing gap.

[0006] The fixed roller is mounted on the frame via bearings, and the movable roller is mounted on a bearing seat via bearings. The bearing seat can be moved by the first drive cylinder, which adjusts the crushing gap between the fixed and movable rollers. Both the fixed and movable rollers are driven by their respective drive motors. The first drive cylinder can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder; this design uses an electric cylinder. The crushing gap can be adjusted according to the size of the material to be crushed, allowing for crushing to the required fineness using only one crusher. The feeding mechanism controls the speed of the material falling into the crushing gap between the fixed and movable rollers, thereby controlling the crushing speed. By preventing material from accumulating on the fixed and movable rollers, the overall crushing uniformity is improved. The material is conveyed at a uniform speed by the movement of the first and second flexible conveyor belts, improving the stability of the material conveying speed.

[0007] Furthermore, the bearing housing includes: The mounting base is connected to the bearing housing and is used to mount the drive unit.

[0008] The mounting base and bearing housing are connected by fasteners such as bolts, or by welding or integral molding. The mounting base is used to install the drive device corresponding to the movable roller, so as to maintain the connection stability between the movable roller and the corresponding drive device when the movable roller moves relative to the frame.

[0009] Furthermore, the bearing housing also includes: The extension connects to the bearing housing; The frame is provided with a movable groove adapted to the bearing seat, and the extension is used to restrict the broken object from passing through the movable groove.

[0010] The extension is connected to the bearing housing by fasteners such as screws, or by welding or integral molding. The extension is located on the inner side of the frame. When the bearing housing moves, the extension can always block the moving groove, thus preventing the crushed material from being placed outside the frame through the moving groove and improving the stability of the crushing process.

[0011] Furthermore, the feeding mechanism also includes: The first conveying surface is placed on the first flexible conveyor belt and the second flexible conveyor belt respectively, and the first conveying surface forms a funnel-shaped feeding cavity.

[0012] The first conveying surface on the first flexible conveyor belt and the second flexible conveyor belt forms a funnel-shaped feeding cavity, which can hold a large amount of material, and then the material is conveyed at a uniform speed through the feeding cavity.

[0013] Furthermore, the feeding mechanism also includes: The second conveying surface is placed on the first flexible conveyor belt and the second flexible conveyor belt respectively, and is located below the first conveying surface. The second conveying surfaces on the first flexible conveyor belt and the second flexible conveyor belt are parallel to each other.

[0014] The second conveying surface is used to control the conveying speed of the material. By having two second conveying surfaces on the first and second flexible conveyor belts parallel to each other, the stability of the material movement is controlled, and the uniform conveying speed of the material is further controlled. In addition, the first and second flexible conveyor belts improve the stability of the material placed on the fixed and movable rollers and reduce the impact of the material on the fixed and movable rollers.

[0015] Furthermore, the feeding mechanism also includes: Guide rollers are mounted on the frame, and the first flexible conveyor belt and the second flexible conveyor belt are respectively wound around the corresponding guide rollers.

[0016] The guide roller is mounted via bearings and is used to guide the movement of the first flexible conveyor belt and the second flexible conveyor belt. The first flexible conveyor belt and the second flexible conveyor belt each have a drive motor, which is connected to one of their respective guide rollers to drive the movement of the first flexible conveyor belt and the second flexible conveyor belt.

[0017] Furthermore, the feeding mechanism also includes: An adjusting seat is movably mounted on the frame, and the guide roller corresponding to the first flexible conveyor belt is movably mounted on the adjusting seat.

[0018] The adjusting seat is slidably mounted on the frame, and the drive motor of the first flexible conveyor belt is mounted on the adjusting seat. The width of the conveying channel is controlled by moving the adjusting seat. All the guide rollers corresponding to the first flexible conveyor belt are movably mounted on the adjusting seat through bearings to ensure the stability of the overall structure.

[0019] Furthermore, the feeding mechanism also includes: The second drive cylinder is installed between the adjusting seat and the frame.

[0020] The second drive rod can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. This design uses an electric cylinder. The second drive cylinder is used to drive the movement and adjustment of the adjustment seat, thereby adjusting the width of the conveying channel.

[0021] The beneficial effects of this application are: 1. The bearing housing can be moved by the control of the first drive cylinder, so as to adjust the crushing gap between the fixed roller and the movable roller. The crushing gap can be adjusted according to the size of the billet to be crushed, so that the required fineness can be achieved by using only one crusher.

[0022] 2. The feeding mechanism controls the speed of the material to be crushed falling into the crushing gap between the fixed roller and the movable roller, thereby controlling the crushing speed and improving the overall crushing uniformity by making it less likely for the material to accumulate on the fixed roller and the movable roller.

[0023] 3. By moving the first flexible conveyor belt and the second flexible conveyor belt, the material is conveyed at a uniform speed, thereby improving the stability of the material conveying speed. Attached Figure Description
