Description

Technical Field

[0001] The utility model belongs to the technical field of transmission belts, and more specifically, particularly relates to a transmission belt roller shaft seat structure. Background Art

[0002] The transmission belt is the transmission medium in the transmission belt system, also known as the conveyor belt. The transmission belt system is a type of transmission system, which includes two or more rollers with transmission belts on them. The rollers can rotate unlimitedly to allow the transmission belt to move forward. One or more of the rollers will be powered to allow the transmission belt to move forward and carry the material transmitted on the transmission belt. The powered rollers are called drive rollers, and the others are called idle rollers. Both drive rollers and idle rollers are installed on the bracket through the shaft seats at both ends.

[0003] The existing publication number CN217177344U discloses a transmission belt roller shaft seat structure. Although the overall installation height is changed by splicing the installation structure, the actual installation height of the transmission belt roller is adjusted, and a limited vibration reduction structure is designed to perform vibration reduction positioning on the longer transmission belt roller from both ends to ensure that the transmission belt roller can rotate stably.

[0004] Based on the above, the inventors have discovered the following problems: However, the shaft seat uses threads to adjust the positions of the two stabilizing seats, and the two threads are adjusted separately. It is easy for the driving roller or the idle roller to not be located in the middle of the mounting hole of the shaft seat after the positions of the two stabilizing seats are adjusted. This has little effect when used for a short time, but the gap between the driving roller or the idle roller and the shaft seat will become larger and larger if used for a long time.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a transmission belt roller shaft seat structure is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a transmission belt roller shaft seat structure to solve the problem that the gap between the driving roller or the idler roller and the shaft seat becomes larger and larger after long-term use.

[0011] Furthermore, the movable plate is arranged in an arc shape, and the inner wall length of the movable plate is 1 / 5 to 1 / 4 of the circumference of the inner wall of the sleeve. There are multiple rollers, and the multiple rollers are arranged equidistantly on one side of the movable plate close to the middle of the sleeve.

[0012] Furthermore, the worm and the worm wheel are located in the same vertical plane, the worm and the worm wheel are meshed with each other, the worm wheel is in the shape of a hollow ring, and the inner wall diameter of the worm wheel is greater than the inner wall diameter of the sleeve.

[0015] 1. In the utility model, the turntable rotates to drive the guide rail to rotate, and the spiral guide rail rotates on the outer wall of the slider, so that the slider moves laterally, driving the four movable plates to move toward the middle of the sleeve at a uniform speed and distance at the same time. When the rollers of the four movable plates all touch the driving roller or the idler roller of the transmission belt, the knob is stopped from being turned. At this time, the roller is located in the middle of the sleeve, thereby achieving the effect of keeping the existing driving roller or the idler roller still located at the center of the mounting hole of the shaft seat after the adjustment is completed.

[0016] 2. In the utility model, the mounting block is installed by passing bolts through the mounting holes. When the height of the shaft seat needs to be adjusted, the horizontal height of the shaft seat can be adjusted by rotating the two threaded rods inside the two threaded sleeves respectively and adjusting the horizontal height of the top of the threaded rods, thereby achieving the effect of quickly adjusting the horizontal height of the shaft seat.

The first telescopic rod 14 and the first telescopic rod 15 cooperate to restrict the slider 19 to prevent the slider 19 from rotating with the guide rail 8. Since the guide rail 8 is spiral, the slider 19 moves laterally, thereby driving the four sliders 19 to move toward the middle at the same time, and driving the four movable plates 17 to move toward the middle of the sleeve 6 at a uniform speed and equidistantly.

[0030] Among them, the movable plate 17 is arranged in an arc shape, and a plurality of rollers 18 are arranged.
