Description

Technical Field

[0001] This utility model relates to the field of raw material crushing technology, and in particular to a raw material crushing device that is safe to operate. Background Technology

[0002] Powder coatings are coatings that exist in solid powder form, mainly composed of resins, curing agents, pigments, fillers, and additives. In the production process, the raw materials are typically extruded into thin sheets, then cooled promptly, and finally pulverized into the desired powder particles using a crushing device. This type of coating offers numerous advantages, including environmental friendliness, energy efficiency, and excellent coating performance, and has been widely used in various fields such as automobiles, home appliances, and construction.

[0003] In the powder coating production process, raw material crushing is a crucial step. Taking a crushing device for powder coating production proposed in patent application CN202322153308.7 as an example, this device lacks necessary protective components. On the one hand, this allows larger foreign objects to be easily conveyed to the crushing rollers without effective obstruction during raw material transport. Once these foreign objects enter the crushing roller area, they may not only damage the crushing rollers, affecting the normal operation and service life of the crushing device, but may also lead to a decline in the quality of the crushed powder coating, or even the production of substandard products. On the other hand, due to the lack of effective isolation from protective components, operators are prone to accidentally touching the high-speed rotating crushing rollers during equipment operation, which undoubtedly poses a significant safety hazard and could cause serious injury to the operator. In summary, some existing powder coating raw material crushing devices are insufficient in terms of safety and reliability due to the lack of protective components. Therefore, this application proposes a raw material crushing device with safe operation to solve the above problems. Utility Model Content

A support component 5 is fixedly installed inside the support frame 2 in front of the lower end of the protective net 15. The support component 5 consists of a base rod 16, a spring 19, two anti-detachment plates 20, connecting rods 21, and contact plates 22. The spring 19 is installed inside the base rod 16. There are two anti-detachment plates 20, which are symmetrically fixed at both ends of the spring 19. There are two connecting rods 21, which are respectively fixedly installed at the outer ends of the two anti-detachment plates 20. There are two contact plates 22, which are respectively fixedly installed at the outer ends of the two connecting rods 21. By setting the protective blocking component 4, composed of the top rod 14 and the protective net 15, in front of the crushing component 3, it is possible to effectively prevent... Larger foreign objects are conveyed by the belt conveyor 1 into the area of ​​the crushing roller 13 during the raw material conveying process, preventing damage to the crushing roller 13 and ensuring the normal operation and service life of the crushing component 3. At the same time, it prevents the quality of the powder coating after crushing from deteriorating and reduces the occurrence of unqualified products. In addition, the protective net 15 can also isolate the crushing roller 13 during equipment operation, reducing the probability of operators accidentally touching the high-speed rotating crushing roller 13, effectively reducing safety hazards and ensuring the personal safety of operators. By setting a support component 5 at the lower end of the protective blocking component 4, which consists of a base rod 16, a spring 19, an anti-detachment plate 20, a connecting rod 21, and a contact plate 22, the support component 5 can support and position the protective blocking component 4, ensuring that the protective blocking component 4 is always in a suitable position and enhancing the protective effect. The protective blocking component 4 and the support component 5 can be moved up and down to adjust according to the protection requirements, thus making the protective blocking component 4 and the support component 5 more practical.

[0021] Specifically, a hopper 6 is fixedly installed at the rear end of the belt conveyor 1. The support frame 2 consists of side plates 7, lifting frames 8, and a top plate 9. There are two side plates 7 and two lifting frames 8, which are respectively installed on the two side plates 7. The top plate 9 is fixedly installed on the upper end of the two side plates 7. Guide rail grooves 11 are opened on the inner wall of the side plates 7, and through grooves 10 are opened on the top plate 9, which pass through the top plate 9 vertically. The crushing assembly 3 consists of a crushing roller 13 and a reduction motor 12. The crushing roller 13 is fixedly connected to the output shaft of the reduction motor 12. The crushing roller 13 is connected to the output shaft of the reduction motor 12. The components are rotatably mounted on two lifting frames 8. The reduction motor 12 is fixedly mounted on the outer end of one of the lifting frames 8. When crushing powder coating raw materials using the belt conveyor 1, support frame 2, and crushing component 3, the powder coating raw materials are first placed on the conveyor belt of the belt conveyor 1. The belt conveyor 1 is started, and the raw materials are conveyed forward with the belt. At the same time, the reduction motor 12 in the crushing component 3 is started. The reduction motor 12 drives the crushing roller 13 to rotate. When the raw materials are conveyed to the crushing roller 13, they are crushed by the rotating crushing roller 13. The crushed powder falls from the feed hopper 6.

[0022] Specifically, the protective blocking assembly 4 is located on the front side of the crushing roller 13, the protective net 15 is slidably installed in the through groove 10, the top rod 14 is located above the top plate 9, the base rod 16 on the support assembly 5 is located inside the support frame 2, and the base rod 16 is fixedly installed at the lower end of the protective net 15. The base rod 16 has an installation through groove 17 that passes through it from front to back. Two through holes 18 are symmetrically opened at the left and right ends of the base rod 16, and the through holes 18 communicate with the installation through groove 17. The spring 19 is located in the installation through groove 17, the anti-detachment plate 20 is movably installed in the installation through groove 17, and the connecting rod 21 is movably installed in the through hole 18. The contact plate 22 is located outside the base rod 16 and contacts the inner wall of the guide rail groove 11. When adjusting the height of the protective blocking assembly 4 and the support assembly 5 according to the protection requirements, the top rod 14 is pushed up or down. The top rod 14 drives the protective net 15 to slide up and down in the through groove 10 of the top plate 9. The base rod 16 at the lower end of the protective net 15 moves accordingly. The spring 19 in the base rod 16 pushes the anti-detachment plate 20, so that the connecting rod 21 drives the contact plate 22 to always contact the guide rail groove 11 on the inner wall of the side plate 7. Thus, after moving to the appropriate height, the support assembly 5 supports and positions the protective blocking assembly 4, ensuring that the protective net 15 is in the required protection position.
