Description

Technical Field

[0001] The utility model relates to the field of textile production equipment, in particular to a sewing machine which is convenient for arranging the sewing edges and preventing them from breaking or falling off. Background Art

[0002] Textiles such as sheets and towels are cut into long strips according to specifications, and then the long towel rolls are fed into the longitudinal sewing machine. During the process, the two long sides are sewn by the flat-bed sewing machines on both sides. Due to various reasons, thread breakage and derailment may occur during the sewing process, and the machine needs to be stopped for adjustment. In the past, the flat-bed sewing machine was fixed in a certain position, which was very inconvenient to handle, and the long towel needed to be reversed, otherwise defective products with unqualified seams would appear. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides a sewing machine which is convenient for tidying up the seam edges when the threads are broken or derailed. The sewing machine can be shifted leftwards and rightwards and backwards, which is convenient for tidying up the seam edges when the threads are broken or derailed.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A sewing machine that is convenient for arranging broken and unthreaded seams includes a flat sewing machine installed on a frame platform, a horizontal linear guide rail 1 is installed on the frame platform, a longitudinal linear module is fixed on the linear guide rail 1, the flat sewing machine is fixed on the longitudinal linear module, a toggle clamp is installed on one side of the linear guide rail 1 on the frame platform, the toggle clamp can be locked with the linear guide rail 1, a sensor is provided on the frame platform below the toggle clamp, and the sensor signal is connected to the electromagnetic valve of the driving telescopic cylinder of the presser foot of the flat sewing machine. When the toggle clamp is opened, the sensor gives a signal to let the flat sewing machine lift the presser foot, and the flat sewing machine can be pulled outward along the linear guide rail 1 to make the flat sewing machine leave the edge of the long towel; at the same time, the flat sewing machine can be shifted forward and backward along the linear module to leave the long towel part where the thread is unthreaded and broken, and after restarting, the flat sewing machine can re-sew the edge from behind the unthreaded and broken thread to ensure the quality of the seam.

[0006] A further improvement is that the slider of the linear guide rail 1 is fixed on the frame platform, the guide rail of the linear module is fixed on the guide rail of the linear guide rail 1, and the base of the sewing machine is fixed on the slider of the linear module.

[0007] A further improvement is that a handle is fixedly connected to the outer end of the guide rail of the linear guide rail 1, so as to facilitate pushing and pulling the lockstitch sewing machine.

[0008] A further improvement is that a limit rod is connected to the lower part of the outer end of the guide rail of the linear guide rail 1, and a limit block is provided at a corresponding position on the frame platform. When the limit is pushed inward, the presser foot of the flat sewing machine is just in place.

[0009] A further improvement is that the frame platform includes a transverse linear guide rail 2 and a platform plate, and the platform plate is mounted on a slider of the linear guide rail 2. When sewing long towels of different widths, it is used to adjust the distance between the two side sewing machines. Beneficial Effects

[0010] The flat-bed sewing machine is installed on a longitudinal and transverse linear guide rail, and is restricted by an elbow clamp. When the seam edge is derailed or broken, the flat-bed sewing machine can be moved outward and backward, away from the edge of the long towel that needs to be trimmed, for easy operation; and after restarting the machine, the flat-bed sewing machine can re-sew the edge from behind the derailed or broken thread to ensure the quality of the seam edge. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 ;

[0013] Figure 3 This is a schematic diagram of the structure of the utility model Figure 3 . DETAILED DESCRIPTION

[0014] like Figures 1 to 3 As shown, the utility model includes a flat sewing machine 1 installed on a frame platform 2, the frame platform 2 includes a horizontal linear guide rail 21 and a platform plate 22, the platform plate 22 is installed on the slider of the linear guide rail 21, the slider 31 of the horizontal linear guide rail 3 is fixed on the upper surface of the platform plate 22 of the frame platform 2, the slider 41 of the longitudinal linear module 4 is fixed on the guide rail 32 of the linear guide rail 1, the bottom plate of the flat sewing machine is fixed on the guide rail 42 of the linear module, a toggle clamp 5 is installed on one side of the linear guide rail 1 on the platform plate 22, the toggle clamp 5 can lock the guide rail 32 of the linear guide rail 1 3, and a sensor 6 is provided on the platform plate 22 below the toggle clamp 5, and the sensor 6 signal is connected to the electromagnetic valve of the telescopic cylinder driving the presser foot of the flat sewing machine 1. A limit rod 8 is connected to the lower outer end of the guide rail of the linear guide rail 3, and a limit block 9 is provided at the corresponding position on the frame platform 2. A handle 7 is fixedly connected to the outer end of the guide rail of the linear guide rail 3.

[0015] When the thread comes off or breaks during sewing, the machine is stopped immediately and the elbow clamp 5 is unlocked and opened. If the sensor 6 cannot detect the elbow clamp, a signal is transmitted to the solenoid valve of the telescopic cylinder driving the presser foot of the sewing machine 1 to lift the presser foot. At the same time, the linear guide 3 is also unfastened, and the handle 7 is grasped to drive the guide of the linear guide 1 to be pulled outward. The sewing machine then leaves the edge of the long towel and can also be shifted backward along the linear module. The operator can tidy up the broken thread without restriction. After tidying up, push the linear guide 1 inward and lock it with the elbow clamp. After restarting the machine, the sewing machine will sew the edge again from behind the broken thread to ensure that the seam is not leaking.

[0016] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
