Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a special embedded automatic clutch for a raising machine. Background Art

[0002] In the process of a large number of applications of raising machines in the textile industry, the requirements for the stability of the raising machines are getting higher and higher. During the normal operation of the raising machine, its main working part is the raising roller, on which the card clothing is wrapped. During the raising process, a large amount of waste hair will be wrapped around the card clothing, which requires a cleaning roller to clean the waste hair on the card clothing to achieve the purpose of continuous operation of the card clothing.

[0003] Under this premise, the cleaning roller and the raising roller are linked by sprocket drive. However, during the working process, due to the damage of the fabric itself or the problem of too large joints, the fabric has a certain probability of being entangled on the cleaning roller, causing damage to the cleaning roller.

[0004] In order to solve the problem of cleaning roller damage, the existing solution is to add a set of embedded clutches to the cleaning roller shaft head. When the cleaning roller is entangled with fabric, the clutch can be disengaged and the power can be cut off. This solution can protect the cleaning roller from damage to a certain extent, but the force of this clutch is all on the cleaning roller, which can easily cause the cleaning roller shaft head to bend and deform. In addition, when the cleaning roller is entangled with fabric, the existing technology cannot detect this situation, causing the clutch to continuously engage and disengage, causing damage to the clutch. Summary of the invention

[0005] The object of the present invention is to provide a special chimeric automatic clutch for a raising machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chimeric automatic clutch specially used for a raising machine, characterized in that it comprises a clutch mounting shaft, a sprocket mounting sleeve coaxially arranged thereon is sleeved on the clutch mounting shaft, and the sprocket mounting sleeve is connected to the mounting shaft through a bearing; a passive sprocket is fixedly arranged at the front end of the sprocket mounting sleeve, and the passive sprocket is connected to the cleaning roller sprocket of the raising machine through a chain; a clutch passive part is fixedly arranged in the middle of the sprocket mounting sleeve, a compression spring cooperating with the clutch passive part is arranged on the sprocket mounting sleeve at the rear of the clutch passive part, and a compression nut assembly is arranged on the outer side of the compression spring; a clutch active part meshing with the clutch passive part is arranged on the sprocket mounting sleeve between the clutch passive part and the passive sprocket, the clutch active part is mounted on the sprocket mounting sleeve through a bearing, a driving sprocket is arranged on the outer surface of the clutch active part, and the driving sprocket is connected to the sprocket of the power source of the raising machine through a chain; after the meshing surfaces of the clutch active part and the clutch passive part are separated, they mesh again between every 120° rotation;

[0007] When fabric is entangled on the bottom brush of the cleaning roller, the transmission resistance between the clutch and the cleaning roller sprocket will increase. When the resistance reaches the clutch's disengagement condition, the clutch's passive component will automatically disengage from the clutch's active component, thereby blocking the transmission between the power source sprocket and the cleaning roller, playing a protective role; after the inspection of the entangled fabric is completed, the clutch's active component and passive component will rotate 120° to re-engage.

[0008] The compression spring uses 65Mn compression spring as the clutch fitting power component. The compression spring applies force to the clutch passive part to make it fit with the active part. Both the active sprocket and the passive sprocket use double-row sprockets.

[0009] The technical problem to be solved by the present invention can also be achieved through the following technical scheme: three groups of meshing teeth are provided on the meshing surfaces of the clutch active part and the clutch passive part, each group of meshing teeth is composed of large teeth and small teeth, both the large teeth and the small teeth are trapezoidal teeth, the distribution angle α of the large teeth is 35°, the distribution angle β of the small teeth is 25°, and the large teeth and small teeth of the three groups of meshing teeth are arranged alternately; after the clutch is disengaged, if it is to be engaged, the meshing teeth will engage again only after the clutch is rotated 120°, and this angle corresponds to the three rows of brushes on the cleaning roller, ensuring that the angle corresponding to the brushes on the cleaning roller and the raising roller will not change due to the disengagement of the clutch.

[0010] The technical problem to be solved by the present invention can also be achieved through the following technical scheme: the clutch mounting shaft is provided with a horizontally arranged shaft body, the front end of the shaft body is fixedly connected with a mounting plate, a long shaft sleeve is mounted on the shaft body, and a blocking plate is provided at the outer end of the long shaft sleeve.

[0011] The technical problem to be solved by the present invention can also be achieved by the following technical solution: the bearing between the sprocket mounting sleeve and the clutch mounting shaft is a deep groove ball bearing, which is provided with two groups, each group is provided with two, one group of bearings is provided at the front passive sprocket, and the other group of bearings is provided at the two ends of the long shaft sleeve. Using two groups of bearings, the two groups of sprockets can be operated independently.

[0012] The technical problem to be solved by the present invention can also be achieved by the following technical solution: the compression nut assembly includes a locking nut matched with a compression spring, a compression nut is arranged outside the locking nut, an external thread is arranged on the rear outer surface of the sprocket mounting sleeve, and the locking nut and the compression nut are both threadedly connected with the external thread. The compression nut assembly adopts a double locking device to ensure that the compression spring will not loosen during the rotation of the clutch.

[0013] The technical problem to be solved by the present invention can also be achieved through the following technical solution: a proximity switch for controlling the power source switch of the raising machine is provided on the outside of the clutch passive component, and the proximity switch is fixed to the raising machine frame through a proximity switch bracket.

[0014] The clutch is independently installed on the raising machine, and is connected to the cleaning roller and power components of the raising machine through sprockets and chains. When the cleaning roller is entangled with fabric, the clutch can effectively block the transmission between the power source and the cleaning roller, and can cut off the power supply of the raising machine through the proximity switch sensor. After the fabric wrapped around the cleaning roller is cleaned, the power supply can be restored, and the clutch can automatically recover to a certain angle and work together normally.

[0015] The passive and active parts of the clutch are both equipped with three groups of meshing teeth, each group of meshing teeth is composed of large teeth and small teeth, the distribution angle α of the large teeth is 35°, the distribution angle β of the small teeth is 25°, and the large teeth and small teeth of the three groups of meshing teeth are arranged alternately; after the clutch is disengaged, if it needs to be engaged, the meshing teeth will engage again only after the clutch rotates 120°. This angle corresponds to the three rows of brushes on the cleaning roller, ensuring that the angle between the brushes on the cleaning roller and the raising roller will not change due to the disengagement of the clutch.

[0016] Compared with the prior art, the clutch of the present invention is installed independently and connected with the cleaning roller and the power component through a sprocket, which solves the problem that the cleaning roller of the raising machine automatically cuts off the power when winding the fabric, effectively protects the cleaning roller and the clutch from damage, and greatly improves the stability of the raising machine.

[0031] The clutch 1 is independently mounted on the raising machine and is connected with the cleaning roller and the power component of the raising machine through a sprocket and a chain.

[0032] When the cleaning roller is wound with fabric, the clutch 1 can effectively block the transmission between the power source and the cleaning roller, and can cut off the power supply of the raising machine through the proximity switch 113. After the fabric wound on the cleaning roller is cleaned, the power supply can be restored, and the clutch can automatically recover to a certain angle and work together normally.

[0033] The clutch is installed independently and connected to the cleaning roller and power components through a sprocket. It solves the problem that the cleaning roller of the raising machine automatically cuts off the power when winding the fabric, effectively protects the cleaning roller and the clutch from damage, and greatly improves the stability of the raising machine.
