[0002] With the growth of the national economy, people's demand for gypsum board for interior decoration is constantly expanding, thus driving the rapid development of the gypsum board industry. Currently, the international and domestic markets are increasingly demanding high-efficiency, multi-variety, and high-quality gypsum board production machines. At present, most gypsum board factories in China use a bearing bushing assembly method to fix the rollers of their gypsum board dryers. This method has low bushing strength, complex structure, and is inconvenient to disassemble and assemble, making cleaning and maintenance difficult. This significantly impacts gypsum board production efficiency. Furthermore, untimely cleaning and maintenance of the dryer can easily lead to the accumulation of damaged gypsum board, which can affect the forming of the gypsum board or even shorten the machine's lifespan.

The roller fixing device has a simple structure, saves time and effort in disassembly and assembly, facilitates maintenance and cleaning of the dryer, and has a significant fixing effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: the roller fixing device includes an installation part and a fixing pin. The installation part is fixed to the end of the roller. The installation part is provided with a first limiting part and a second limiting part that are spaced apart. A locking groove is formed between the first limiting part and the second limiting part. The installation position is provided with an installation hole that matches the installation part and a limiting hole that matches the second limiting part. The first limiting part and the second limiting part are provided with fixing holes. The fixing pin is set in the fixing hole.

[0005] Preferably, the first limiting part is located on the side of the mounting part away from the roller, and the second limiting part is located on the side of the mounting part closer to the roller. Specifically, the first limiting part can be configured as an annular shape, and the second limiting part can be configured as a boss with a horizontal side and a third side between the two sides being an arc shape.

[0006] Preferably, two second limiting parts are symmetrically arranged on both sides of the mounting part, and two limiting holes are symmetrically arranged on both sides of the mounting hole.

[0007] Preferably, the mounting hole is a circular hole, the shape of the limiting hole is adapted to the shape of the second limiting part, and the size of the limiting hole is greater than or equal to the size of the second limiting part.

[0008] Preferably, it also includes a bushing, the cylindrical bushing being disposed inside the mounting part, and both ends of the roller being disposed inside the bushing.

[0009] Preferably, the end of the roller is fixed with a shaft head, the end of the shaft head is fixed inside the bushing, and a sprocket is provided on the shaft head.

[0010] Preferably, the fixed pin has a limiting part at one end near the first limiting part, the diameter of the limiting part being larger than the diameter of the fixing hole, and a bent fixing part at the other end of the fixed pin, which is engaged in the installation position.

[0011] Compared with the prior art, the beneficial effects of this technical solution are as follows: The first limiting part and the second limiting part of this utility model form a locking groove, and the fixed roller is provided with a mounting hole for the mounting part to pass through and a limiting hole for the second limiting part to pass through. The mounting part is locked by the locking groove, and then the fixing pin passes through the fixing holes of the first limiting part and the second limiting part in sequence to fix the mounting part. When disassembling, it is only necessary to remove the fixing pin first, and then rotate the mounting part so that the second limiting part can be removed from the limiting hole. The structure is simple and the disassembly and assembly are convenient. Attached Figure Description

[0017] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0018] Reference Figures 1-4The roller fixing device includes an installation part 1 and a fixing pin. The installation part 1 of this utility model is a hollow cylinder. A first limiting part 2 and a second limiting part 3 are provided on the outer side along the circumference. The first limiting part 2 and the second limiting part 3 are spaced apart to form a locking groove 4. The first limiting part 2 is annular. The second limiting part 3 is a boss symmetrically arranged on both sides of the installation part 1. The shape of each boss is that the two sides are horizontally arranged, and the third side between the two sides is arc-shaped.

[0019] The frame 8 is provided with multiple parallel mounting brackets 12, and the mounting part 1 is mounted on the mounting bracket 12. The mounting bracket 12 is provided with mounting holes 5 and limiting holes 501. The mounting holes 5 are circular holes with a diameter larger than that of the mounting part 1. The two limiting holes 501 are symmetrically arranged on both sides of the mounting holes 5, and the shape of the limiting holes 501 is the same as that of the boss. The size of the limiting holes 501 is larger than that of the boss, so that the second limiting part 3 can pass through the limiting holes 501.

[0020] After the mounting part 1 passes through the mounting hole 5 and the second limiting part 3 passes through the limiting hole 501, the mounting part 1 is rotated so that the second limiting part 3, which was originally parallel to the limiting hole 501, rotates to a direction perpendicular to the limiting hole 501. The mounting bracket 12 is engaged in the engaging groove 4, that is, the mounting part 1 is engaged on the frame 8.

[0021] Fixing holes 13 are provided at the same position on the first limiting part 2, the frame 8, and the second limiting part 3. There are two fixing holes 13, which are respectively set on the edge of the boss. The fixing pin passes through the fixing holes 13 of the first limiting part 2, the mounting bracket 12, and the second limiting part 3 in sequence. The fixing pin of this utility model is a 7-shaped pin 6. The horizontal end of the 7-shaped pin 6 is set to fit against the outer surface of the first limiting part 2, and the vertical end is set to face downward, so as to fix the mounting part 1 on the mounting bracket 12.

[0022] It also includes a bushing 7, which is interference-fitted into the internal cavity of the mounting part 1. The end of the internal cavity of the mounting part 1 away from the roller 9 has a protrusion. The two sides of the bushing 7 are fixed in the mounting part 1 by the axial force of the protrusion and the roller 9. The bushing 7 of this utility model is made of graphite.

[0023] The roller 9 has shaft heads 901 at both ends, which are welded to the rotating part in the middle. The sprocket 11 is fixed on the shaft head 901. The mounting bracket 12 has a fixing plate for mounting the chain 10. The chain 10 is positioned corresponding to the sprocket 11. After the roller 9 is inserted into the bushing 7 at both ends, the sprocket 11 is placed on the chain 10. Thus, the roller 9 is driven to rotate by the chain 10 and the sprocket 11, thereby realizing the transportation of gypsum board.

[0024] Working process: After the mounting part 1 and the second limiting part 3 pass through the mounting hole 5 and the limiting hole 501, rotate the mounting part 1 so that the first limiting part 2 and the second limiting part 3 are locked on both sides of the mounting bracket 12. The 7-pin 6 is inserted into the fixing hole 13 of the first limiting part 2, the second limiting part 3 and the mounting bracket 12 in sequence, and the fixing end of the 7-pin 6 is set downwards to fix the mounting part 1 on the mounting bracket 12.

[0025] The sprocket 11 is installed at the shaft end 901 of the roller 9. Then, the end of the shaft end 901 of the roller 9 is inserted into the bushing 7. The sprocket 11 is placed on the chain 10. The sprocket 11 drives the roller 9 to rotate, thereby transporting the gypsum board.

[0026] When the gypsum board needs to be cleaned during the operation of the dryer, simply pull out the 7-pin 6, rotate the mounting part 1 so that the second limiting part 3 can disengage from the limiting hole 501, and then the roller 9 can be pulled out from the mounting bracket 12. After cleaning or maintenance, it can be reinstalled in its original position.

[0027] The present invention has two fixing holes 13. During use, the 7-pin 6 is only set in the lower fixing hole 13. After a period of use, when the lower fixing hole 13 is severely worn, the mounting part 1 is rotated to swap the upper and lower fixing holes 13 and insert the 7-pin 6 into the new fixing hole 13 to ensure the stability of use.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
