Description

Technical Field

[0001] The utility model relates to the technical field of knitting, in particular to a rotating base for a large cloth folding machine. Background Art

[0002] During the production process, as the fabric is continuously conveyed, the fabric needs to be neatly folded to avoid the disorderly stacking of the fabric, which will cause wrinkles and affect the quality of the fabric. The folding machine is a device that can neatly fold the produced fabric. Existing folding machines are usually fixed on large circular knitting machines (referred to as large circular machines or circular weft machines) and driven by the large circular machines to rotate synchronously. When the large circular machine or the folding machine fails, the other party will continue to rotate, causing the fabric on the large circular machine to be pulled and formed into waste. Utility Model Content

[0003] Therefore, in view of the above problems, the utility model proposes a rotating base for a large-scale cloth folding machine which has a reasonable structure, reduces losses caused by failures and operates smoothly.

[0004] To solve this technical problem, the utility model adopts the following scheme: a rotating base for a large cloth folding machine, comprising a base, and also comprising an encoder, an induction switch, a servo motor, a controller and a support seat, the upper surface of the base is connected to the bottom of the cloth-moving frame of the large cloth folding machine, and the lower surface of the base is rotatably connected to the upper surface of the support seat, the lower surface of the base is provided with a driven shaft and the driven shaft is sleeved with a driven gear, the servo motor is arranged on the support seat and the output end of the servo motor is connected with a driving shaft, the driving shaft is sleeved with a driving gear, the driving gear is meshed with the driven gear, the servo motor drives the driving shaft to rotate, drives the driving gear to rotate, and then drives the driven gear to rotate to make the base rotate on the support seat, the induction switch recognizes the rotation speed of the large circular machine in real time and feeds it back to the controller through the encoder, and the output end of the controller is connected to and controls the servo motor.

[0005] As a further improvement, an upwardly extending annular boss is provided on the circumference of the upper surface of the support seat, and an annular ring with an inner diameter matching the outer diameter of the annular boss of the support seat is provided on the lower surface of the base, and the annular ring of the base can be rotatably mounted on the annular boss of the support seat.

[0006] As a further improvement, an upwardly extending annular boss is provided on the circumference of the upper surface of the support seat, and an annular ring with an outer diameter matching the inner diameter of the annular boss of the support seat is provided on the lower surface of the base, and the annular ring of the base can be rotatably embedded in the annular boss of the support seat.

[0007] A further improvement also includes a reducer, and the servo motor is connected to the reducer to drive the driving shaft to rotate.

[0008] By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: the rotation speed of the large circular machine is identified in real time by the induction switch and fed back to the controller through the encoder, and then the controller controls the servo motor according to the feedback induction information to directly drive the driving shaft to rotate, drive the driving gear to rotate, and then drive the driven gear to rotate so that the base rotates on the support seat, so that the base of the cloth folding machine adjusts the required rotation speed according to the cloth output speed of the large circular machine and the material requirements of the cloth to follow the rotation, when the large circular machine fails, the controller promptly controls the servo motor to stop driving, and reduces the loss caused by the failure, and at the same time, the autonomous drive of the cloth folding machine can also facilitate the adaptive adjustment of the rotation speed according to the elasticity or softness of the cloth, so that the stacking efficiency of the cloth is higher, the stacking effect of the cloth is better and smoother, and the operation of the overall machine is more stable, and through further settings, that is, the cooperation of the annular ring of the base and the annular boss on the support seat, the rotating structure between the base and the support seat is more stable, and the servo motor directly drives the base to rotate more stably, which can be widely promoted and applied.
