Description

Technical Field

[0001] The utility model relates to the technical field of cylinder alignment, and more specifically, to a conveyor belt driving device. Background Art

[0002] In the existing conveying device, materials are transported through a conveyor belt. When the conveyor belt is transmitting, the conveyor belt is prone to left - right deviation. Therefore, a deviation rectifying device is required to rectify the deviation of the conveyor belt. The conveyor belt is sleeved on the driving wheel and the driven wheel. The driven wheel is installed on the installation shaft, and deviation rectifying devices are sleeved on both ends of the driven wheel. The deviation rectifying device includes a bushing and a deviation rectifying structure, and the center distance of the left - right deviation rectifying structures of the driven wheel is ensured through the bushing.

[0003] After research by the inventor, it is found that in the prior art, for example, in Chinese Patent No. 202420033531X, most bushings are hollow cylinders. Since the driven wheel rotates relative to the installation shaft, one end of the bushing contacts the rotating end face of the driven wheel, and the other end contacts the static end face of the deviation rectifying structure. Once the clamping force of the driven wheel and the deviation rectifying structure on this bushing is too large, it will cause excessive resistance and slipping of the driven wheel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a conveyor belt driving device, which can avoid the slipping of the bushing.

[0031] Please refer to Figure 1 , in some existing conveyor belt driving devices 1, the conveyor belt driving device 1 includes a frame body (not shown in the figure) and a driving member. At both ends of the frame body along its extending direction, there are provided a mounting shaft 10 and a driving shaft (not shown in the figure). A driven wheel 20 and a driving wheel are respectively mounted on the mounting shaft and the driving shaft. The driving member (not shown in the figure) is connected to the driving shaft, and the driving member is used to drive the driving shaft to rotate. The conveyor belt is sleeved on the driving wheel and the driven wheel 20. There are also provided two deviation rectifying assemblies 30 respectively located on both sides of the driven wheel 20 on the mounting shaft.

[0032] The following will introduce in detail the specific structure of a conveyor belt driving device provided by an embodiment of the present utility model and the corresponding technical effects brought thereby with reference to the patent drawings.

[0033] Please refer to Figure 2 , a conveyor belt driving device provided by an embodiment of the present utility model includes a mounting shaft, a driven wheel 20, and a deviation rectifying assembly 30. The driven wheel 20 is mounted on the mounting shaft and can rotate relative to the mounting shaft. The deviation rectifying assembly 30 includes a bushing 33 and a deviation rectifying structure that are sleeved on the mounting shaft and arranged in sequence along the axial direction of the mounting shaft. Both ends of the bushing 33 respectively abut against one end face of the driven wheel 20 and one end of the deviation rectifying structure, and the deviation rectifying structure is fixedly connected to the mounting shaft.

[0034] The bushing 33 includes an outer moving ring 331 and an inner moving ring. The outer moving ring 331 is sleeved on the inner stationary ring 332 and can move relative to the inner stationary ring 332. One end of the outer moving ring 331 abuts against the end face of the driven wheel 20. The inner stationary ring 332 is fixedly sleeved on the mounting shaft and one end thereof abuts against the deviation rectifying structure. It can be understood that since the inner stationary ring 332 of the bushing 33 in this embodiment is fixedly sleeved on the mounting shaft, and the inner stationary ring 332 abuts against the stationary end face of the deviation rectifying structure, and the outer moving ring 331 can rotate relative to the inner stationary ring 332 and abuts against the rotating end face of the driven wheel 20, therefore, under the action of the inner stationary ring 332 and the outer moving ring 331, it can effectively prevent the bushing 33 from slipping under the clamping of the driven wheel 20 and the deviation rectifying structure.

[0035] Specifically, in this embodiment, the deviation rectifying structure includes a support seat 32 and a deviation rectifying cylinder 31. One end of the support seat 32 away from the deviation rectifying cylinder 31 abuts against the end face of the inner stationary ring 332. It should be noted that the support seat 32 is used to connect with the external frame body to support the mounting shaft. The deviation rectifying cylinder 31 can drive the support seat 32 to move axially, so that the driven wheel 20 moves axially to correct the deviation of the sleeve on the driven wheel 20.

[0036] Optionally, a first water blocking portion 3311 is provided at one end of the outer moving ring 331 away from the driven wheel 20. The first water blocking portion 3311 extends towards the outer peripheral wall of the inner stationary ring 332. The first water blocking portion 3311 is arranged in a ring shape. It can be understood that through the first water blocking portion 3311, it can effectively prevent external water vapor or impurities from entering the bushing 33.

[0037] Optionally, a second water blocking portion arranged in a ring shape also protrudes from the inner peripheral wall of the outer moving ring 331. The second water blocking portion abuts against the outer peripheral wall of the inner stationary ring 332. The second water blocking portion is located on the side of the first water blocking portion 3311 close to the driven wheel 20. That is to say, through the second water blocking portion, it further prevents water vapor and external impurities from entering between the inner stationary ring 332 and the outer moving ring 331, so as to avoid affecting the rotation of the outer moving ring 331 relative to the inner stationary ring 332.

[0038] Specifically, a water blocking groove 3312 is formed in the second water blocking portion. A water blocking protrusion 3321 protrudes from the inner stationary ring 332. The water blocking protrusion 3321 is located in the water blocking groove 3312. Through the cooperation of the water blocking groove 3312 and the water blocking protrusion 3321, most impurities can be prevented from entering between the outer moving ring 331 and the inner stationary ring 332.

[0039] Specifically, in this embodiment, the outer surface of the water blocking protrusion 3321 is in an arc shape. The arc-shaped water blocking protrusion 3321 can effectively prevent the inner stationary ring 332 from having a stress concentration phenomenon to ensure the service life of the inner stationary ring 332.

[0040] Among them, in order to prevent the water-blocking protrusion 3321 from affecting the rotation of the outer moving coil 331 relative to the inner stationary coil 332, a preset gap should be provided between the water-blocking protrusion 3321 and the bottom wall of the water-blocking groove. The bottom wall of the water-blocking groove 3312 faces the outer peripheral wall of the inner stationary coil 332.

[0041] In order to reduce the friction between the outer moving coil 331 and the inner stationary coil 332 during rotation, in this embodiment, the bushing 33 further includes a bearing 335. The outer moving coil 331 is sleeved on the inner stationary coil 332 through the bearing 335 for rotation. It can be understood that reducing friction means reducing energy loss and improving the overall efficiency of the mechanical system. By reducing friction and vibration, the bearing 335 can reduce the noise level of the mechanical system, reduce the relative friction between the outer moving coil 331 and the inner stationary coil 332, and effectively improve the service life of the bushing 33.

[0042] The thrust plain bearing 335 ensures the smooth rotation of the outer moving coil 331 relative to the inner stationary coil 332. The thrust plain bearing 335 can bear axial force. The thrust plain bearing 335 is specially designed to bear axial loads and can effectively support the axial movement of the outer moving coil 331 relative to the inner stationary coil 332. By bearing axial loads, the thrust plain bearing 335 can ensure that the outer moving coil 331 does not undergo axial displacement during rotation, improving the stability of the structure.

[0043] It can be understood that in order to prevent the bushing 33 from getting damp and rusty, the bearing 335 can be a fully stainless steel special bearing 335.

[0044] Optionally, the bushing 33 further includes a first sealing ring 333. The first sealing ring 333 is sleeved on the outer peripheral surface of the inner stationary coil 332. The outer moving coil 331 is hermetically connected to the inner stationary coil 332 through the first sealing ring 333. The first sealing ring 333 can be an O-ring. Through the first sealing ring 333, water and dust can be prevented.

[0045] It should be noted that the first sealing ring 333 is axially located on the side of the second water-blocking part away from the first water-blocking part 3311.

[0046] Optionally, a second sealing ring 334 is provided at one end of the outer moving coil 331 away from the deviation correction structure. That is to say, a second sealing ring 334 is provided at one end of the outer moving coil 331 away from the support seat 32. The second sealing ring 334 abuts against the end face of the driven wheel 20.

[0047] It can be understood that since the second sealing ring 334 can also be an O-ring, through the setting of the second sealing ring 334, not only can water and dust be prevented, but also the friction between the end face of the driven wheel 20 and the end face of the outer moving coil 331 can be increased to prevent slipping between the outer moving coil 331 and the driven wheel 20.

[0048] In summary, a conveyor belt driving device provided by an embodiment of the present invention includes a mounting shaft, a driven wheel 20 and a deviation rectifying assembly 30. The driven wheel 20 is mounted on the mounting shaft and can rotate relative to the mounting shaft. The deviation rectifying assembly 30 includes a bushing 33 and a deviation rectifying structure that are sleeved on the mounting shaft and arranged in sequence along the axial direction of the mounting shaft. Both ends of the bushing 33 abut against one end surface of the driven wheel 20 and one end of the deviation rectifying structure respectively, and the deviation rectifying structure is fixedly connected to the mounting shaft. The bushing 33 includes an outer moving ring 331 and an inner moving ring. The outer moving ring 331 is sleeved on the inner static ring 332 and can move relative to the inner static ring 332. One end of the outer moving ring 331 abuts against the end surface of the driven wheel 20, and the inner static ring 332 is fixedly sleeved on the mounting shaft and one end thereof abuts against the deviation rectifying structure. Under the action of the inner static ring 332 and the outer moving ring 331, it is possible to effectively prevent the bushing 33 from slipping under the clamping of the driven wheel 20 and the deviation rectifying structure.

[0049] The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
