[0002] Some moving parts on a carding machine are generally driven by belts. The belt is fitted between the driving pulley and the driven pulley and is always taut during transmission. Over time, the belt will loosen and lengthen. However, since the distance between the driving pulley and the driven pulley is constant, the loose belt will detach from the pulley, affecting the normal operation of the equipment and potentially causing safety accidents in severe cases.

The carding cylinder motor pulley anti-detachment bracket includes a support plate, a mounting bracket fixedly connected to the back of the support plate, a track opening on the front of the support plate, a sliding block engaged with the inner wall of the track opening, a first bearing fixedly embedded on the front of the sliding block, and a tension roller fixedly connected to the inner ring of the first bearing.

[0004] When the device is in use, the limiting sliding roller can restrict the side of the motor belt. However, the limiting sliding roller is pushed by a spring to fit against the edge of the belt in order to achieve the purpose of restriction. However, in daily operation, the pushing of the spring will give the belt a lateral force, which may cause the belt to deviate during daily operation and affect the normal operation of the belt.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-4 As shown, a carding cylinder motor pulley anti-detachment bracket includes a main board 1. A mounting plate 2, which is fixed to the carding machine, is fixed to one side of the main board 1. A lifting mechanism body 3 is provided on the surface of the mounting plate 2. A lifting block 4, which works in conjunction with the lifting mechanism body 3, slides within the inner cavity of the main board 1. A moving block 7 is slidably provided within the inner cavity of the lifting block 4. A telescopic rod 6 is fixed to the surface of the moving block 7. The other end of the telescopic rod 6 is fixed to the inner cavity of the lifting block 4. A spring 5 is sleeved on the surface of the telescopic rod 6. One end of the spring 5 is fixed to the surface of the moving block 7, and the other end is fixed to the inner cavity of the lifting block 4. A rotating rod 8 is fixed to the surface of the moving block 7. A rotating cylinder 9 is rotatably provided on the surface of the rotating rod 8. A fixing limit ring 10 is fixed to one side of the surface of the rotating cylinder 9. The bracket also includes: An auxiliary mechanism 11 is set on one side of the surface of the rotating rod 8 to cooperate with the fixed limit ring 10. Both sides of the surface of the main board 1 are fixed with slide barrels 13. An adjustment mechanism 14 is set on the surface of the slide barrels 13. A limit sliding roller 16 is set on the surface of the adjustment mechanism 14.

[0017] In use, the position of the limiting sliding roller 16 and the moving block 7 can be adjusted by the adjusting mechanism 14, so that the limiting sliding roller 16 and the fixed limiting ring 10 can fit against the edge of the belt, thereby achieving the function of limiting the edge of the belt. It can be applied to belts of different widths. In addition, under the action of the auxiliary mechanism 11 and the fixed limiting ring 10, belts of different widths can also be limited to achieve the function of preventing deviation.

[0018] The auxiliary mechanism 11 includes a first threaded rod 111 fixed to one end of the rotating rod 8. A first engagement block 112 is engaged with the surface of the first threaded rod 111. An action sleeve 113 is fixed to the surface of the first engagement block 112. A fixing ring 114 is fixed to one end of the action sleeve 113. A rotating ring 115 is rotatably disposed on the surface of the fixing ring 114. In this embodiment, through the arrangement of the first threaded rod 111, the first engagement block 112, the action sleeve 113, the fixing ring 114, and the rotating ring 115, when the first engagement block 112 rotates, the first engagement block 112 engaged with the surface of the first threaded rod 111 can drive the action sleeve 113 and the fixing ring 114 to rotate. Thus, under the meshing force of the first threaded rod 111 and the first engagement block 112, the first engagement block 112 drives the rotating ring 115 to move, thereby changing the relative distance between the rotating ring 115 and the fixed limiting ring 10.

[0019] The surface of the first engaging block 112 is fixed with several anti-slip ridges 12, which are made of rubber. In this embodiment, the anti-slip ridges 12 facilitate the rotation of the first engaging block 112 by the operator, thus improving the practicality of the device.

[0020] The adjustment mechanism 14 includes a second threaded rod 141 that rotates on the surface of the main board 1. A second engagement block 142 engages with the surface of the second threaded rod 141. A second push rod 144 is fixed on both sides of the surface of the second engagement block 142. One end of the limiting sliding roller 16 is fixed to the surface of the second push rod 144. The second push rod 144 slides in the inner cavity of the slide barrel 13. A first push rod 143 is fixed on one side of the surface of the second engagement block 142. The first push rod 143 slides in the inner cavity of the moving block 7. In this embodiment, by setting the second threaded rod 141, the second engagement block 142, the first push rod 143, and the second push rod 144, when the second threaded rod 141 and the second engagement block 142 engage, the limiting sliding roller 16 and the moving block 7 can move under the action of the second push rod 144 and the first push rod 143. This can change the working area of ​​the rotating drum 9 and the limiting sliding roller 16, thereby improving the applicability of this device.

[0021] The thread helix angle of the second threaded rod 141 is less than the equivalent friction angle, which makes the second threaded rod 141 self-locking. In this embodiment, with this setting, after the second threaded rod 141 and the second meshing block 142 move relative to each other, the second meshing block 142 can be stably stopped at a designated position, thereby improving the practicality of the device.

[0022] The first threaded rod 111 also has self-locking properties.

[0023] A rotating head 15 is fixed to one end of the second threaded rod 141. The rotating head 15 has a groove on its surface. In this embodiment, the rotating head 15 provides a force point for the operator to rotate the second threaded rod 141, thereby improving the practicality of the device.

[0024] Working principle: In use, the main board 1 is first installed on the carding machine frame via the mounting plate 2. During use, the rotating drum 9 is supported at the bottom of the belt, and the lifting mechanism body 3 moves the rotating drum 9 upward via the lifting block 4 to support and tension the belt, preventing the belt from becoming loose on the pulley. The lifting mechanism body 3 and the lifting block 4 are existing technologies. At this time, the operator can use the adjusting mechanism 14. Under the action of the second threaded rod 141 and the second meshing block 142, the first push rod 143 drives the moving block 7 to move, and the second push rod 144 drives the limiting sliding roller 16 to move, so that the limiting sliding roller 16 fits against the edge of the belt, and the fixed limiting ring 10 fits against the edge of the belt.

[0025] Then, the auxiliary mechanism 11 can be used. When the first meshing block 112 rotates, the first meshing block 112 meshing with the surface of the first threaded rod 111 can drive the sleeve 113 and the fixed ring 114 to rotate. Then, under the meshing force of the first threaded rod 111 and the first meshing block 112, the first meshing block 112 drives the rotating ring 115 to move, thereby changing the relative distance between the rotating ring 115 and the fixed limiting ring 10. Then, under the action of the fixed limiting ring 10 and the rotating ring 115, the other edge of the belt can be restricted, thereby achieving the function of preventing belt deviation.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
