Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-derailment devices, and in particular to an anti-derailment device for an elastic driven wheel of a spinning machine. Background Technology
[0002] A spinning machine is a machine that processes fiber raw materials into yarn or thread. It is widely used in the textile industry. The main function of a spinning machine is to process fiber raw materials through a series of processes, such as opening, mixing, combing, doubling, twisting and winding, to finally produce finished products such as cotton yarn, linen yarn, wool yarn and silk thread. These finished products have good strength and toughness and are widely used in industries such as fabrics, clothing, carpets, veneers and webbing.
[0003] Spinning machines are equipped with multiple round belts to form a stable power transmission with pulleys. However, when the spindles, rollers and other components of the spinning machine rotate at high speed, they will cause strong vibrations, resulting in frequent jumping of the round belts. This greatly increases the risk of the belts falling off the pulleys. In addition, once the spindles of the spinning machine are accidentally tangled with yarn, the load will increase dramatically in an instant. At this time, the friction force on the round belts cannot be matched, and they are forced to slip in the pulley grooves. They are prone to jumping off the pulley grooves, thus affecting the normal operation of the spinning machine. Therefore, an anti-derailment device for the elastic driven pulley of a spinning machine is proposed. Utility Model Content

[0030] Example 1
[0031] Reference Figure 1 - Figure 3 The first embodiment of this utility model provides an anti-derailment device for an elastic driven wheel of a spinning machine, comprising: a transmission unit 100, an anti-derailment unit 200, and a moving unit 300;
[0032] The transmission unit 100 includes a base 101 and a portal plate 102 fixedly connected to the top of the base 101. Two pulleys 103 are rotatably connected to the top of the portal plate 102, and a round belt 104 is drivenly connected to each of the two pulleys 103.
[0033] An anti-derailment unit 200 is disposed above the base 101. The anti-derailment unit 200 is used to prevent the round belt 104 from falling off the pulley 103.
[0034] The moving unit 300 is mounted on the base 101 and adjusts the position of the anti-derailment unit 200.
[0035] Two pulleys 103 are used to guide and convey the round belt 104. When the round belt 104 jumps or slips due to vibration or other factors, the anti-derailment unit 200 can dynamically and elastically limit the two round belts 104 to prevent them from falling off the pulleys 103. The moving unit 300 can adjust the distance between the anti-derailment unit 200 and the pulleys 103 to limit round belts 104 of different diameters or thicknesses.
[0036] Example 2
[0037] Reference Figure 1 and Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the anti-derailment unit 200 includes a support plate 201 located above the base 101. A rotating column 202 is rotatably connected to the top of the support plate 201. A driven wheel 203 is fixedly connected to the top of the rotating column 202. An internal threaded sleeve 204 is fixedly connected to the bottom of the rotating column 202. The internal threaded sleeve 204 slides through the support plate 201. An adjusting rod 205 is threadedly connected to the bottom of the inner cavity of the internal threaded sleeve 204. A torsion spring 206 is sleeved on the internal threaded sleeve 204. One end of the torsion spring 206 is fixed to the bottom of the support plate 201, and the other end of the torsion spring 206 is fixed above the adjusting rod 205.
[0038] Driven wheel 203 is used to limit the circular belts 104 of the two pulleys 103, and driven wheel 203 does not contact the two circular belts 104. The internal threaded sleeve 204 can rotate and move up and down. When the circular belts 104 fall off the pulleys 103, the circular belts 104 will contact the driven wheel 203. The circular belts 104 drive the driven wheel 203 to rotate through friction, so that the driven wheel 203 can contact the moving circular belts 104, and through torsion... The spring 206 prevents the driven wheel 203 from rotating continuously. When the driven wheel 203 rotates to the limit of the torsion of the torsion spring 206, the driven wheel 203 remains in balance and stops rotating, so as to prevent the round belt 104 from falling off the rotating driven wheel 203. When the round belt 104 vibrates, the driven wheel 203 can use the elasticity of the torsion spring 206 to make a vertical elastic jump to adapt to the jump of the round belt 104 and prevent the round belt 104 from slipping off the driven wheel 203.
[0039] By manually fixing the driven wheel 203, the adjusting rod 205 can be rotated. The adjusting rod 205 can stretch the torsion spring 206. By adjusting the torque of the torsion spring 206, the torque of the torsion spring 206 cannot drive the adjusting rod 205 to rotate. This allows adjustment of the angle of rotation of the driven wheel 203 due to friction. When the round belt 104 is loose, the torque of the torsion spring 206 is increased to reduce the rotation range of the driven wheel 203 so that the detached round belt 104 can contact the driven wheel 203 and be quickly pushed back onto the pulley 103. When the round belt 104 is too tight, the torque of the torsion spring 206 is reduced to increase the rotation range of the driven wheel 203, thereby preventing slippage when the pulley 103 contacts the driven wheel 203. When the round belt 104 is driving smoothly, it automatically returns to the pulley 103.
[0040] Furthermore, a fixing plate 207 is fixedly connected to the top of the support plate 201. A limiting rod 208 slides through one side of the fixing plate 207. The outer wall of the rotating column 202 is provided with multiple square grooves 209 that fit the limiting rod 208. A spring 210 is sleeved on the limiting rod 208. One end of the spring 210 is fixed to one side of the limiting rod 208, and the other end of the spring 210 is fixed to one side of the fixing plate 207. The end of the limiting rod 208 facing the rotating column 202 is square. A ring of anti-slip protrusions is provided at the bottom of the adjusting rod 205.
[0041] By pushing the limiting rod 208 into the corresponding square groove 209, the rotating column 202 can be locked, so that the adjusting rod 205 can be rotated to adjust the tension of the torsion spring 206. When the limiting rod 208 is released, the spring 210 pushes the limiting rod 208 away from the rotating column 202 to prevent the limiting rod 208 from getting stuck in the square groove 209. The square end of the limiting rod 208 can be inserted into the square groove 209. The square end can improve the stability of the limiting rod 208 in limiting the rotating column 202. The anti-slip protrusion at the bottom of the adjusting rod 205 allows the worker to rotate the adjusting rod 205 to dynamically adjust the driven wheel 203.
[0042] Example 3
[0043] Reference Figure 1 and Figure 2 This is the third embodiment of the present invention. Unlike the previous embodiment, the moving unit 300 includes a moving block 301 fixedly connected to the bottom of the support plate 201, a vertical plate 302 fixedly connected to the top of the base 101, a round rod 303 fixedly connected to one side of the vertical plate 302, one end of the round rod 303 slidingly passing through the moving block 301, and a threaded rod 304 rotatably connected to one side of the moving block 301, one end of the threaded rod 304 passing through the vertical plate 302 and threadedly connected to the vertical plate 302.
[0044] By rotating the threaded rod 304, the moving block 301 can be moved along the round rod 303. The moving block 301 can move the support plate 201 to adjust the distance between the driven wheel 203 and the pulley 103. When a round belt 104 of different diameter or thickness is installed on the pulley 103, the distance between the driven wheel 203 and the pulley 103 is adjusted to avoid direct friction between the driven wheel 203 and the round belt 104, which would cause wear.
[0045] Furthermore, a pair of rollers 305 are rotatably connected to both sides of the movable block 301, and each roller 305 is slidably disposed on the upper surface of the base 101. A scale plate 306 is fixedly connected to the top of the base 101, and a triangular arrow 307 is fixedly connected to one side of the movable block 301.
[0046] When the movable block 301 moves, the roller 305 can support the movable block 301 and improve the smoothness of the movement of the movable block 301. The triangular arrow 307 points to the scale line on the scale plate 306 so that the user can accurately adjust the gap between the driven wheel 203 and the pulley 103, so that the driven wheel 203 can be in the appropriate position when changing the round belt 104 of different sizes.
[0047] During use, the distance between the driven wheel 203 and the pulley 103 is adjusted by rotating the threaded rod 304, and the driven wheel 203 is moved to a suitable position using the triangular arrow 307 and the scale plate 306. Then, the limiting rod 208 is pushed to insert into the square groove 209 at the corresponding position to lock the rotating column 202. Next, the adjusting rod 205 is rotated according to the tension of the round belt 104 to adjust the torque and elasticity of the torsion spring 206. After adjustment, the limiting rod 208 is released, and the spring 210 pushes the limiting rod 208 away from the rotating column 202. When the round belt 104 falls off any of the pulleys 103, the round belt 104 will contact the driven wheel 203 and drive the driven wheel 203 to rotate through friction.
[0048] When the driven wheel 203 rotates to the limit of the torsion spring 206, the driven wheel 203 stops rotating to prevent the round belt 104 from falling off the rotating driven wheel 203. When the round belt 104 vibrates, the driven wheel 203 can make vertical elastic jumps to prevent the round belt 104 from jumping and slipping off the driven wheel 203. The driven wheel 203 adapts to the tension change of the round belt 104 and forms a dynamic limit through vertical elastic jumps and horizontal elastic rotation. When the round belt 104 is driving smoothly, the round belt 104 is automatically pulled back to the pulley 103, and the driven wheel 203 is automatically rotated and reset by the torsion spring 206.
[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
