Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene sewing threads, and particularly relates to a polytetrafluoroethylene functional sewing thread incision leveling mechanism. Background Technique

[0002] Polytetrafluoroethylene is a heat-resistant and cold-resistant material, and also has good corrosion resistance. Therefore, polytetrafluoroethylene can be made into polytetrafluoroethylene fibers, and multiple groups of polytetrafluoroethylene fibers can be twisted into polytetrafluoroethylene sewing threads. During the use of existing polytetrafluoroethylene sewing threads, sometimes it is necessary to cut them. At this time, the fibers at the incision of the polytetrafluoroethylene sewing thread will disperse, resulting in the inability of personnel to conveniently pass the polytetrafluoroethylene sewing thread through the corresponding needle holes, thus affecting work efficiency. Therefore, we introduce a new polytetrafluoroethylene functional sewing thread incision leveling mechanism. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a polytetrafluoroethylene functional sewing thread incision leveling mechanism, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A polytetrafluoroethylene functional sewing thread incision leveling mechanism includes a fixed seat. A placing mechanism is arranged at the left part of the upper end of the fixed seat. A cutting seat is arranged at the right part of the upper end of the fixed seat. A cutting groove is arranged in the middle of the upper end of the cutting seat. A controller is arranged at the front part of the placing mechanism. A fixed column is arranged in the middle of the upper end of the fixed seat. A U-shaped seat is arranged at the upper end of the fixed column. A roller is movably installed inside the U-shaped seat through a movable shaft. A wire groove is arranged on the outer surface of the roller. Telescopic cylinders are arranged at the front part and the rear part of the upper end of the fixed seat. Support frames are arranged at the upper ends of the two telescopic cylinders. A fixing plate is fixedly installed between the two support frames. Two connecting columns are arranged at the lower end of the fixing plate. A connecting plate is fixedly installed at the lower ends of the two connecting columns. A cutting knife is fixedly installed at the lower end of the connecting plate. Telescopic rods are fixedly installed through the left part and the right part of the upper end of the fixing plate. Limiting plates are fixedly installed at the lower ends of the two telescopic rods. Protective pads are arranged at the lower ends of the two limiting plates.

[0006] Preferably, the position of the cutting knife corresponds to that of the cutting groove up and down, and the cutting knife is located between the two limiting plates.

[0007] Preferably, the positions of the limiting plates and the roller are on the same horizontal line.

[0008] Preferably, the placing mechanism includes a support plate. There are two support plates. In the middle of the upper ends of the two support plates, limiting grooves are provided. An installation rod is jointly arranged inside the two limiting grooves. External threads are provided on both the front and rear surfaces of the outer surface of the installation rod. Limiting sleeves are movably installed on both the front and rear surfaces of the outer surface of the installation rod through the external threads. A winding roller is movably sleeved on the outer surface of the installation rod.

[0009] Preferably, the two limiting sleeves are closely attached to the two support plates respectively.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By turning on two telescopic cylinders through a controller, the two telescopic cylinders drive the two support frames to move downward, and then drive the cutting knife to move downward. At the same time, the two telescopic rods also move downward, so that the two protective pads below the two limiting plates are in close contact with the surface of the thread, which is convenient for fixing both ends of the thread and preventing the problem of uneven cut due to deviation during cutting. At this time, the cutting knife does not contact the surface of the thread, but because there is a spring on the inner upper wall of the telescopic rod, the two telescopic cylinders can continue to drive the cutting knife to move downward until cutting is completed. The cut sewing thread with a flat cut is convenient for personnel to pass it through the needle hole, improving work efficiency;

[0012] 2. By sleeving the winding roller for winding the thread on the outer surface of the installation rod, then placing the installation rod inside the two limiting grooves, and fixing the installation rod between the two support plates through the two limiting sleeves. By pulling out one end of the thread on the winding roller and making it pass through the wire groove, and then passing it through the cutting seat, so that the thread is located between the cutting groove and the cutting knife, preventing the problem of line deviation.

[0022] A leveling mechanism for the incision of a polytetrafluoroethylene functional sewing thread, comprising a fixed seat 1. A placing mechanism 2 is arranged at the left part of the upper end of the fixed seat 1. A cutting seat 3 is arranged at the right part of the upper end of the fixed seat 1. A cutting groove 4 is arranged in the middle of the upper end of the cutting seat 3. A controller 5 is arranged at the front part of the placing mechanism 2. A fixed column 6 is arranged in the middle of the upper end of the fixed seat 1. A U-shaped seat 7 is arranged at the upper end of the fixed column 6. A roller 8 is movably installed inside the U-shaped seat 7 through a movable shaft. A wire groove 9 is arranged on the outer surface of the roller 8. Telescopic cylinders 10 are arranged at the front part and the rear part of the upper end of the fixed seat 1. Support frames 11 are arranged at the upper ends of the two telescopic cylinders 10. A fixing plate 12 is fixedly installed between the two support frames 11. Two connecting columns 13 are arranged at the lower end of the fixing plate 12. A connecting plate 14 is fixedly installed at the lower ends of the two connecting columns 13. A cutting knife 15 is fixedly installed at the lower end of the connecting plate 14. Telescopic rods 16 are inserted and fixedly installed at the left part and the right part of the upper end of the fixing plate 12. Limit plates 17 are fixedly installed at the lower ends of the two telescopic rods 16. Protective pads 18 are arranged at the lower ends of the two limit plates 17.

[0023] In this embodiment, the positions of the cutting knife 15 and the cutting groove 4 correspond up and down, and the cutting knife 15 is located between the two limit plates 17; the positions of the limit plates 17 and the roller 8 are on the same horizontal line.

[0024] In this embodiment, the placing mechanism 2 includes support plates 21. There are two support plates 21. Limit grooves 22 are arranged in the middle of the upper ends of the two support plates 21. An installation rod 23 is arranged inside the two limit grooves 22. External threads 24 are arranged on the front part and the rear part of the outer surface of the installation rod 23.
