Description

TECHNICAL FIELD

[0001] The utility model relates to a cloth edge cutting device. BACKGROUND

[0002] Before making daily necessities such as clothes or quilt covers with cloth, the excess cloth edges on both sides of the cloth generally need to be cut off. An edge cutting machine is a machine that replaces traditional manual work to cut and trim the edges of required objects. Depending on the size of the objects to be cut, the edge cutting machine can have various sizes. Compared with the past, using a machine to process the edges of objects greatly improves production efficiency.

[0003] However, when cutting and trimming the cloth, the cloth is a soft material, so it needs to be manually flattened and straightened or fixed by other large equipment to prevent the cloth from collapsing and accumulating due to insufficient support when cutting the edges, thereby affecting the cutting quality of the cloth. If the cloth is manually supported, the production efficiency will still be reduced.

[0004] In addition, due to the movement of the cloth under the pulling force, the running path of the cloth is often affected by many factors and cannot follow the predetermined path. Therefore, the cloth often deviates during running, and there is no corresponding method to deal with the deviation of the cloth on the current edge cutting machine. SUMMARY

[0005] The utility model provides a cloth edge cutting device, and the cloth edge cutting device can automatically adjust the deviated cloth.

[0006] The technical solution to solve the above problems is as follows:

[0007] The cloth edge cutting device comprises a rack, a first cloth guide roller, an edge cutting mechanism, a pinch roller mechanism, a driving mechanism, an ultrasonic sewing mechanism for sewing the edges of the cloth, a controller, the first cloth guide roller is connected with the rack, the edge cutting mechanism is arranged on the rack and located downstream of the first cloth guide roller, the pinch roller mechanism is installed on the rack and located downstream of the edge cutting mechanism, the driving mechanism is connected with the pinch roller mechanism, the ultrasonic sewing mechanism is installed on the rack and cooperates with the edge cutting mechanism, the controller is connected with the edge cutting mechanism and the driving mechanism, and the cloth edge cutting device further comprises a deviation correction mechanism connected with the controller and located upstream of the first cloth guide roller, the deviation correction mechanism comprises a detection assembly for detecting the position of the cloth and a deviation correction assembly for correcting the position of the cloth, the deviation correction mechanism is connected with the rack, the deviation correction assembly comprises a rotating shaft, a first connecting assembly, a second connecting assembly, a first roller, a second roller, and a linear actuator, the rotating shaft is pivotally connected with the rack, the first connecting assembly is fixed with the rotating shaft, one end of the first roller and the second roller is connected with the first connecting assembly, the other end of the first roller and the second roller is connected with the second connecting assembly, and the linear actuator is respectively hinged with the rack and the second connecting assembly.

[0008] Under the traction force of the pinch roller mechanism, the cloth is continuously moved, and since the cloth will pass through the first tension roller, the second tension roller, the first roller and the second roller in turn, the photoelectric sensor detects the side edge of the cloth, and once the photoelectric sensor cannot detect the side edge of the cloth, it indicates that the position of the cloth has deviated, at this time, the controller controls the linear driver to work, and the linear driver drives the deviation correction assembly to swing, so as to adjust the position of the first roller and the second roller, and then correct the position of the cloth.
