Description

Technical Field

[0001] This utility model relates to the field of crushing equipment, specifically a roller blade assembly for a crusher. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. The material is cut and crushed by the roller blade assembly inside the crusher. Different crushing rollers are required depending on the type of material, such as metal, ore, rubber, and fiber.

[0003] While existing crusher roller assemblies can crush materials, when dealing with different types of materials, such as metals, plastics, stones, or paper, it is often necessary to prepare multiple corresponding crushing rollers to achieve the desired crushing effect. In actual use, due to the large size and heavy weight of the crushing rollers, changing the crushing rollers for different types of materials will greatly increase the working time and also pose certain safety hazards, preventing the crusher from completing the crushing work quickly and affecting the cutting efficiency.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] like Figures 1-10 As shown, a roller cutter assembly for a crusher includes a housing 1, a pitch-changing mechanism, and a rotation mechanism;

[0031] The rotating mechanism includes two drive components, two first crushing rollers 2, two second crushing rollers 3, and two third crushing rollers 4. Each drive component is disposed inside the housing 1, and each first crushing roller 2, each second crushing roller 3, and each third crushing roller 4 is disposed inside one drive component.

[0032] The pitch-changing mechanism includes two U-shaped frames 8, an adjustment component, and a guide component. Each U-shaped frame 8 is located below a drive component. The adjustment component is located on one side of the two U-shaped frames 8, and the guide component is located on the side of the two U-shaped frames 8 away from the adjustment component.

[0033] like Figures 1-10 As shown, each drive assembly includes a first motor 5, a rotating shaft 9, two rotating disks 6, and three second motors 7. The first motor 5 is fixedly mounted on one side of one of the U-shaped frames 8, the rotating shaft 9 is rotatably mounted on the other side of the U-shaped frame 8, one of the rotating disks 6 is rotatably mounted on one side of the U-shaped frame 8, and the output end of the first motor 5 is fixedly connected to the U-shaped frame 8 and the rotating disk 6. The other rotating disk 6 is fixedly mounted on the outer wall of the rotating shaft 9. The two ends of one first crushing roller 2, one second crushing roller 3, and one third crushing roller 4 are respectively rotatably connected to the two rotating disks 6. Each second motor 7 is fixedly mounted on the outer wall of one of the rotating disks 6, and the output ends of the three second motors 7 are respectively fixedly connected to the first crushing roller 2, the second crushing roller, and the two third crushing rollers 4.

[0034] When it is necessary to crush materials, the controller controls the first motor 5 to work, which drives the rotating disk 6 to rotate. The rotating disk 6 drives the first crushing roller 2, the second crushing roller 3, and the third crushing roller 4 to rotate. As needed to crush materials, the positions of the first crushing roller 2, the second crushing roller 3, and the third crushing roller 4 are switched, and the crushing roller that can better crush the corresponding materials is rotated to the appropriate position. After the two required crushing rollers are rotated to the appropriate positions, the second motor 7 is controlled to work, which drives the corresponding crushing roller to rotate, so that the two corresponding crushing rollers rotate simultaneously to crush the materials.

[0035] like Figures 1-10As shown, the adjustment assembly includes a lead screw 10, a guide rod 11, a third motor 14, two mounting plates 12, and two sliders 13. The two mounting plates 12 are fixedly mounted on the inner wall of the outer casing 1. The lead screw 10 is rotatably mounted between the two mounting plates 12. The third motor 14 is fixedly mounted on one side of one of the mounting plates 12 and is fixedly connected to one end of the lead screw 10. The guide rod 11 is fixedly mounted between the two mounting plates 12. Each slider 13 is sleeved on the guide rod 11 and the lead screw 10, and each slider 13 is threadedly engaged with the lead screw 10. One end of each slider 13 is fixedly connected to one end of a U-shaped frame 8.

[0036] During crushing, depending on different usage requirements, the material may need to be crushed into different sizes. At this time, the distance between the two corresponding crushing rollers needs to be adjusted. By controlling the third motor 14 to work, the screw 10 is driven to rotate, so that the screw 10 drives the two sliders (13) to move closer or further away from each other, thereby driving the two U-shaped frames 8 to move closer or further away, and thus adjusting the distance between the two corresponding crushing rollers to achieve the purpose of crushing different sizes.

[0037] like Figures 1-10 As shown, the guide assembly includes a guide groove 15 and two guide blocks 16. The guide groove 15 is formed on the inner wall of the housing 1. Each guide block 16 is fixedly disposed at the end of a U-shaped frame 8 away from the slider 13, and each guide block 16 is slidably connected to the guide groove 15.

[0038] When the U-shaped frame 8 moves, it will drive the guide block 16 fixed on one side to move together, providing guidance and support for the movement of the U-shaped frame 8.

[0039] like Figures 1-10 As shown, two first grooves 17 are provided on one side of the outer wall surface of the outer casing 1 for the slider 13 to slide, and a second groove 18 is provided on the side of the outer casing 1 away from the slider 13 for the first motor 5 to move. A first protective shell 19 is provided on the outer wall of the first groove 17, and a second protective shell 20 is provided on the outer wall of the second groove 18.

[0040] By opening a first groove 17 on the outer wall surface of the outer casing 1, the slider 13 can slide in the first groove 17. By opening a second groove 18 on the outer wall surface of the other side of the outer casing 1, the first motor 5 will not be limited when it moves. The first protective shell 19 and the second protective shell 20 protect the two parts.

[0041] like Figures 1-10 As shown, a Y-shaped frame 21 is provided between every two rotating disks 6;

[0042] The Y-shaped frame 21 isolates the four different crushing rollers, preventing materials from mixing into the other crushing rollers and avoiding the mixing of different types of materials during the next cut, which would affect the purity of the materials. It also prevents different materials from damaging the crushing rollers that are not suitable for the material.
