Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to an anti-reverse transmission roller structure. Background Technology

[0002] A drive roller in textile machinery is a roller used to transmit power in textile machinery. Through rotational motion, it transmits power from one point to another, thereby driving other components of the textile machinery to perform their functions.

[0003] Currently, traditional textile drive rollers on the market often lack anti-reverse mechanisms. This allows the drive rollers to reverse due to inertia after losing power support, leading to a series of hazards. Therefore, there is an urgent need for a drive roller structure with anti-reverse functionality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-reverse drive roller structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The anti-reverse drive roller structure includes a worm gear and a housing. A drive roller is rotatably mounted inside the housing, and a steel sleeve is fixedly fitted on the drive roller. The worm gear is mounted on the steel sleeve via a bearing, and a fixing ring is fixedly installed on the inner wall of the worm gear. A special-shaped part is adapted to fit the fixing ring on the outer wall of the steel sleeve. Multiple wedge-shaped parts are fixedly mounted on the special-shaped part, and a wedge-shaped cavity is adapted to fit each wedge-shaped part on the inner wall of the fixing ring.

[0007] Furthermore, in a preferred configuration, a worm gear is installed inside the housing via a drive motor, and the worm gear is connected to a worm wheel drive.

[0008] In addition, a preferred structure is that a first side cover is provided on one side of the worm gear, and the first side cover has multiple threaded holes.

[0009] Furthermore, in a preferred configuration, a second side cover is provided on the other side of the worm gear, and a screw is adapted to be provided on each of the corresponding threaded holes on the second side cover.

[0010] In addition, the preferred structure is that the irregular part is composed of multiple counterclockwise inclined columnar bodies, the irregular part is arranged in a ring and fixed on the steel sleeve by screws, and both the irregular part and the steel sleeve are provided with screw grooves to match the screws.

[0011] Furthermore, in a preferred configuration, all wedge-shaped members are fixedly mounted on the top of the columnar body, and the inclined surfaces of the wedge-shaped members are all opened in a clockwise direction.

[0012] The beneficial effects of this utility model are as follows: the worm can drive the worm wheel to rotate, and the rotation of the worm wheel can drive the transmission roller to rotate. Through the matching arrangement between the irregular part, the wedge part and the fixed ring and the wedge cavity, not only can the steel sleeve and the transmission roller rotate in a point rotation form, but the reverse rotation of the steel sleeve and the transmission roller can also be prevented.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-7The anti-reverse drive roller structure includes a worm gear 1 and a housing 7. A drive roller 73 is rotatably mounted inside the housing 7. A steel sleeve 5 is fixedly fitted onto the drive roller 73. The worm gear 1 is mounted on the steel sleeve 5 via a bearing 60, and a fixing ring 4 is fixedly installed on the inner wall of the worm gear 1. A shaped part 51 is adapted to fit the fixing ring 4 on the outer wall of the steel sleeve 5. Multiple wedge-shaped parts 52 are fixedly mounted on the shaped part 51, and a wedge-shaped cavity 41 is adapted to fit each wedge-shaped part 52 on the inner wall of the fixing ring 4.

[0023] The outer casing 7 contains a worm gear 72 driven by a drive motor 71, and the worm gear 72 is connected to the worm wheel 1. It is worth noting that the specific transmission mechanism between the drive motor 71, the worm gear 72, and the worm wheel 1 is existing technology, and therefore will not be elaborated upon in this technical solution.

[0024] The worm gear 1 has a first side cover 2 on one side, with multiple threaded holes 21. A second side cover 3 is located on the other side of the worm gear 1, with screws 31 fitted onto each of the threaded holes 21. Through holes are fitted onto both the worm gear 1 and the retaining ring 4 corresponding to the screws 31. The first side cover 2 and the second side cover 3 are fixedly installed on both sides of the worm gear 1 through the fitting and engagement of the screws 31 and the threaded holes 21. A sealing element is provided between the first side cover 2 and the second side cover 3, allowing lubricating oil to be filled inside the worm gear 1, thereby improving the transmission effect of the worm gear 1 on the transmission roller 73.

[0025] The irregularly shaped component 51 is composed of multiple counterclockwise inclined columnar bodies. The irregularly shaped component 51 is arranged in a ring and fixedly sleeved on the steel sleeve 5 by screws 53. Both the irregularly shaped component 51 and the steel sleeve 5 have screw grooves adapted to the screws 53. The wedge-shaped components 52 are all fixedly arranged on the top of the columnar bodies, and the inclined surfaces of the wedge-shaped components 52 are all opened in a clockwise direction.

[0026] In this embodiment, the transmission roller 73 is rotatably mounted on the housing 7 via bearings, and a worm gear 72 is driven inside the housing 7 via a drive motor 71, thereby enabling the transmission of the worm wheel 1 through the worm gear 72.

[0027] Since the worm gear 1 is rotatably mounted on the steel sleeve 5 via the bearing 6, and the steel sleeve 5 is fixedly fitted onto the drive roller 73, the steel sleeve 5 can rotate inside the worm gear due to friction during the rotation of the worm gear 1, thereby driving the drive roller 73 to rotate. It is worth noting that, due to the limitation of friction, the rotational speed of the steel sleeve 5 and the drive roller 73 is slower than the rotational speed of the worm gear 1.

[0028] Furthermore, a fixing ring 4 is fixedly installed on the inner wall of the worm gear 1, and a shaped component 51 is adapted to fit the fixing ring 4 on the steel sleeve 5. Moreover, the shaped component 51 is composed of multiple counterclockwise inclined columnar bodies. This makes the friction between the worm gear 1 and the steel sleeve 5 smaller when the worm gear 1 rotates clockwise, so that the steel sleeve 5 can rotate within the inner wall of the worm gear 1.

[0029] When the worm gear 1 stops rotating, the steel sleeve 5 and the drive roller 73 may reverse due to inertial force. At this time, the friction between the worm gear 1 and the steel sleeve 5 increases, thereby preventing the steel sleeve 5 from reversing on the inner wall of the worm gear 1.

[0030] Furthermore, the fitting arrangement between the wedge-shaped member 52 and the wedge-shaped cavity 41 not only further prevents the steel sleeve 5 and the drive roller 73 from reversing due to inertial force, but also ensures that when the worm gear 1 rotates, the steel sleeve 5 and the drive roller 73 inside rotate in a point-like manner, rather than a smooth rotation, thereby improving the output efficiency of the drive roller 73. It is worth noting that the output efficiency of the drive roller 73 is higher when rotating in a point-like manner; this is existing technology, so the specific principle will not be elaborated further.

[0031] It is worth noting that the drive motor 72 in this application is a low-speed motor, and the transmission speed in this application is all low-speed operation.

[0032] In this utility model, the worm gear 72 can drive the worm wheel 1 to rotate, thereby driving the transmission roller 73 to rotate through the rotation of the worm wheel 1. Through the matching arrangement between the irregular part 51, the wedge part 52, the fixed ring 4, and the wedge cavity 41, not only can the steel sleeve 5 and the transmission roller 73 rotate in a point rotation manner, but the reverse rotation of the steel sleeve 5 and the transmission roller 73 can also be prevented.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
