Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a gap adjustment device for a flux double-roll crusher. Background Technology

[0002] As a key piece of machinery, crushers can precisely crush large particles into smaller particles, playing an indispensable role in many industries such as mining, metallurgical processing, construction, highway and railway construction, water conservancy projects, and chemical manufacturing. Flux, as an important auxiliary material in the welding process, is mainly used in welding processes such as submerged arc welding and electroslag welding. In the production process of flux, crushers are usually needed to crush the raw materials of flux to the size specifications that meet the process requirements, thereby ensuring the production quality and performance of flux.

[0003] A search of Chinese patent with publication number "CN220310524U" reveals "a crusher". This crusher has a vibration mechanism installed at the bottom of the discharge hopper. Through vibration, the material in the hopper jumps and vibrates continuously, thereby ensuring the uniform conveying of the material in the discharge hopper, effectively avoiding blockage of the material during the conveying process, and ensuring the stable operation of production and processing.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the crusher is in use, the position of its crushing components is in a fixed state, making it difficult to flexibly adjust the gap between the crushing components according to actual needs. Given the complex and diverse flux production process, this fixed gap design makes the crusher less applicable to flux production scenarios and needs to be improved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a gap adjustment device for a flux roller crusher, which solves the technical problem of insufficient applicability of existing crushers.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A gap adjustment device for a flux double-roll crusher, comprising the crusher body;

[0010] The crusher body has symmetrically fixed gap adjustment structures installed on its side wall;

[0011] The gap adjustment structure includes a fixed frame, with a self-locking motor on each of the two fixed frames' side walls. Each of the two fixed frames has a first sliding groove inside, and a bidirectional lead screw is rotatably mounted inside each of the two first sliding grooves. The two bidirectional lead screws are fixedly mounted to the output shaft of the self-locking motor. First sliders are symmetrically slidably mounted inside each of the two first sliding grooves. The activation of the two self-locking motors can drive the bidirectional lead screws to rotate and engage in threaded transmission with the first sliders, causing the two first sliders inside the first sliding grooves to move away from or closer to each other. A rotating seat and a reduction motor are fixedly mounted on the upper end of each first slider. A crushing roller body is located between each reduction motor and the rotating seat. Both crushing roller bodies are located inside the crusher body and are rotatably mounted to the rotating seat. Both crushing roller bodies are fixedly mounted to the output shaft of the reduction motor.

[0012] Preferably, the crusher body has symmetrical through slots inside, the two crushing roller bodies are located between the through slots, the upper end of the crusher body is symmetrically provided with guide plates, the two rotating seats and the side wall of the reduction motor are all fixedly installed with connecting rods, and each connecting rod is fixedly installed with a push plate between each pair of them.

[0013] Preferably, both push plates are fixedly installed with the guide plates, the crusher body has symmetrically opened second sliding grooves inside, and the lower ends of both guide plates are symmetrically fixedly installed with second sliders, each of the second sliders being slidably installed inside the second sliding groove.

[0014] (III) Beneficial Effects

[0015] Firstly, by setting up a gap adjustment structure, the operator can turn on the self-locking motor to drive the bidirectional lead screw to rotate and generate threaded transmission with the first slider, so that the two first sliders inside the first groove move away from or closer to each other, thereby driving the rotating seat and the reduction motor to move, thus completing the gap adjustment of the crushing roller body and improving its applicability.

[0016] Secondly, by symmetrically equipping the upper end of the crusher body with guide plates and setting connecting rods on the rotating seat and the reduction motor, the operator can move the push plate when adjusting the crushing roller body, thereby synchronously adjusting the guide plates. This ensures that the material can accurately and evenly enter the crushing area between the crushing roller bodies, avoiding material deviation or scattering, and improving the accuracy and stability of the material guide.

[0023] This application provides a gap adjustment device for a flux-driven roller crusher, effectively solving the technical problem of insufficient applicability of existing crushers. By setting a gap adjustment structure, the operator can activate a self-locking motor to drive a bidirectional lead screw to rotate and generate threaded transmission with the first slider, causing the two first sliders inside the first groove to move away from or towards each other. This, in turn, moves the rotating seat and the reduction motor, thereby completing the gap adjustment of the crushing roller body and improving applicability. Furthermore, by symmetrically providing guide plates at the upper end of the crusher body and setting connecting rods on the rotating seat and the reduction motor, the operator can move the push plate when adjusting the crushing roller body, thereby synchronously adjusting the guide plates. This ensures that the material can accurately and evenly enter the crushing area between the crushing roller bodies, avoiding material deviation or scattering, and improving the accuracy and stability of the material guidance.

[0024] Example

[0025] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient applicability of existing crushers. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a gap adjustment device for a flux double-roll crusher, including a crusher body 11;

[0027] A gap adjustment structure is symmetrically fixedly installed on the side wall of the crusher body 11;

[0028] The gap adjustment structure includes a fixed frame 12, with a self-locking motor 13 on each side wall of the two fixed frames 12. Each fixed frame 12 has a first slide groove 14 inside, and a bidirectional lead screw 15 is rotatably installed inside each of the two first slide grooves 14. Both bidirectional lead screws 15 are fixedly installed to the output shaft of the self-locking motor 13. First sliders 16 are symmetrically slidably installed inside each of the two first slide grooves 14. The activation of the two self-locking motors 13 can drive the bidirectional lead screw 15 to rotate and generate threaded transmission with the first sliders 16, causing the two first sliders 16 inside the first slide grooves 14 to move away from or closer to each other. A rotating seat 17 and a reduction motor 18 are fixedly installed at the upper end of each first slider 16. A crushing roller body 19 is provided between each reduction motor 18 and the rotating seat 17. Both crushing roller bodies 19 are located inside the crusher body 11. Both crushing roller bodies 19 are rotatably installed to the rotating seat 17, and both crushing roller bodies 19 are fixedly installed to the output shaft of the reduction motor 18.

[0029] By setting a gap adjustment structure, the operator can turn on the self-locking motor 13 to drive the bidirectional lead screw 15 to rotate and generate threaded transmission with the first slider 16, so that the two first sliders 16 inside the first slide groove 14 move away from each other or closer to each other, thereby driving the rotating seat 17 and the reduction motor 18 to move, thereby completing the gap adjustment of the crushing roller body 19 and improving its applicability.

[0030] The crusher body 11 has symmetrical through slots 21 inside, and the two crushing roller bodies 19 are located between the through slots 21. The upper end of the crusher body 11 is symmetrically provided with guide plates 22. The two rotating seats 17 and the side walls of the reduction motor 18 are all fixedly installed with connecting rods 23, and push plates 24 are fixedly installed between each pair of connecting rods 23.

[0031] By symmetrically providing guide plates 22 at the upper end of the crusher body 11 and setting connecting rods 23 on the rotating seat 17 and the reduction motor 18, the operator can drive the push plate 24 to move when adjusting the crushing roller body 19, thereby synchronously driving the guide plates 22 to adjust, ensuring that the material can accurately and evenly enter the crushing area between the crushing roller bodies 19, avoiding material deviation or scattering, and improving the accuracy and stability of the material guide.

[0032] Both push plates 24 are fixedly installed with the guide plate 22. The crusher body 11 has symmetrically opened second slide grooves 25. The lower ends of both guide plates 22 are symmetrically fixedly installed with second sliders 26. Each second slider 26 is slidably installed inside the second slide groove 25.

[0033] By setting the second slide groove 25 and the second slider 26, when the guide plate 22 moves, the guide plate 22 can drive the second slider 26 to slide inside the second slide groove 25, thereby providing additional stability.

[0034] Working principle:

[0035] The first step is to adjust the spacing of the crushing roller body 19. At this time, the operator can open the fixed frame 12, so that the output shaft of the fixed frame 12 drives the bidirectional lead screw 15 to rotate, and then conducts threaded transmission with the first slider 16. This causes the first slider 16 in the two fixed frames 12 to move closer to each other. At the same time, the first slider 16 will slide inside the first slide groove 14, so that the two rotating seats 17 and the reduction motor 18 respectively drive the crushing roller body 19 to move closer to each other, thereby completing the spacing adjustment.

[0036] In the second step, when the rotating seat 17 and the reduction motor 18 move, the rotating seat 17 and the reduction motor 18 will synchronously drive the connecting rod 23 and the push plate 24 to move. At the same time, the second slider 26 will slide inside the second slide groove 25, driving the guide plate 22 to adjust synchronously, ensuring the accuracy of subsequent feeding.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
