[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. The operator holds the T-shaped rod and rotates it to drive the two driving bevel gears, driven bevel gears, and threaded rod to rotate, causing the sliding block to slide on the fixed plate. This adjusts the position of the left conveyor roller, thereby adjusting the tension of the conveyor belt.

The hollow roller 13 is provided with a dust removal mechanism.

[0025] It should be noted that: when the workpiece is conveyed on the conveyor belt 4, the dust adhering to the workpiece will fall onto the conveyor belt 4. The dust removal mechanism can clean the dust adhering to the outer wall of the conveyor belt 4. The position of the left conveyor roller 3 can be adjusted by the adjustment mechanism, thereby adjusting the tension of the conveyor belt 4 to meet different conveying needs.

[0026] The adjustment mechanism includes a T-shaped rod 8 that passes through and is rotatably connected to two fixed plates 6. Two driving bevel gears 9 are fixedly connected to the outer wall of the T-shaped rod 8. Each driving bevel gear 9 meshes with a driven bevel gear 10. Both driven bevel gears 10 are coaxially fixedly connected to threaded rods 11. The two threaded rods 11 pass through the corresponding fixed plates 6 and are rotatably connected to them. The two threaded rods 11 also pass through the corresponding sliding blocks 7 and are threadedly connected to them.

[0027] It should be noted that rotating the T-shaped rod 8 drives the two threaded rods 11 to rotate synchronously, causing the left conveyor roller 3 to move and adjust the tension of the conveyor belt 4.

[0028] The dust removal mechanism includes a rotary joint 18 that is fixedly connected to the front end roller shaft of the hollow roller 13. The rotary joint 18 is fixedly connected to a connecting pipe 17. The connecting pipe 17 passes through the fixed column 12 on the front side and is fixedly connected to it. The top of the base 1 is fixedly connected to a negative pressure fan 14 and a dust collection box 15. The air outlet of the negative pressure fan 14 is fixedly connected to the side wall of the dust collection box 15. The inner wall of the dust collection box 15 is fixedly connected to a filter screen 16. The end of the connecting pipe 17 is fixedly connected to the side wall of the dust collection box 15.

[0029] It should be noted that the hollow roller 13, the connecting pipe 17, and the dust collection box 15 are connected, and dust can be collected through the dust collection box 15.

[0030] A motor 5 is fixedly connected to the side wall of the right front column 2. The output shaft of the motor 5 passes through the column 2 and is rotatably connected to it. The end of the output shaft of the motor 5 is coaxially fixedly connected to the right conveyor roller 3.

[0031] It should be noted that motor 5 can drive conveyor belt 4 to rotate, thereby transporting the workpiece.

[0032] A sliding opening is provided through the fixed plate 6, and the outer wall of the sliding block 7 is slidably connected to the inner wall of the sliding opening.

[0033] It should be noted that the tension of the conveyor belt 4 is adjusted by sliding the sliding block 7 within the sliding opening.

[0034] The outer wall of the hollow roller 13 is fitted with multiple soft brushes, and multiple through holes are opened through the hollow roller 13.

[0035] It should be noted that the outer wall of the conveyor belt 4 can be cleaned with a soft brush, and air and dust can be collected through the through holes.

[0036] The outer wall of the rear end roller shaft of the right-side conveyor roller 3 is fixedly connected to a drive wheel, and the outer wall of the rear end roller shaft of the hollow roller 13 is fixedly connected to a driven wheel. The outer walls of the drive wheel and the driven wheel are together fitted with a belt 19.

[0037] The working principle of this utility model is as follows: Starting the motor 5, the output shaft of the motor 5 drives the right-side conveyor roller 3, the conveyor belt 4, and the left-side conveyor roller 3 to rotate. The rotation of the conveyor belt 4 transports the workpiece. The operator holds the T-shaped rod 8 and rotates it, causing the two driving bevel gears 9, the driven bevel gear 10, and the threaded rod 11 to rotate, causing the sliding block 7 to slide on the fixed plate 6. This adjusts the position of the left-side conveyor roller 3, thereby adjusting the tension of the conveyor belt 4. Adjustments can be made according to the condition of the conveyor belt 4 to ensure appropriate conveying force and stable transport. The rotation of the right-side conveyor roller 3 drives the belt 19 and the hollow roller 13 to rotate. Furthermore, the conveyor belt 4 and the hollow roller 13 rotate in the same direction. The brush installed on the outer wall of the hollow roller 13 can clean the bottom of the conveyor belt 4, removing dust and impurities adhering to the conveyor belt 4 and ensuring the cleanliness of the surface of the conveyor belt 4. When the negative pressure fan 14 is started, the air in the dust collection box 15 is drawn away to form a negative pressure. The dust generated by the brush cleaning the surface of the conveyor belt 4 is injected into the hollow roller 13 along with the air, and then into the dust collection box 15 through the connecting pipe 17. The air in the dust collection box 15 is filtered and intercepted by the filter screen 16, so that the dust is concentrated in the dust collection box 15, completing the dust collection and ensuring the air quality.

[0038] This invention solves the problem of existing technologies where a large amount of dust adheres to the outer wall of workpieces during machining, and when the workpieces are transported by a belt conveyor, a large amount of dust adheres to the outer wall of the conveyor belt. This dust damages and corrodes the conveyor belt, accelerates mechanical wear, pollutes the air, and harms the health of workers. Furthermore, the conveyor belt may become loose and lead to poor conveying efficiency during prolonged operation.
