Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt wires, in particular to a cutting device for processing nylon hot-melt wires. Background Art

[0002] Hot-melt yarn is a product made of various textile fibers into a certain fineness, which is used for weaving, rope making, thread making, knitting and embroidery, etc. Nylon hot-melt yarn is a product made of polyamide fibers into a certain fineness.

[0003] During the production process of hot-melt wire, the finished hot-melt wire is wound on a paper roll. After the winding is completed, the hot-melt wire needs to be cut and the paper roll needs to be replaced. Since the hot-melt wire is very thin, it is difficult to find the broken end after the wire is broken. In addition, the broken end will rebound under the action of its own elastic properties after being cut off, which will cause the tail of the winding to become loose, which is not conducive to the winding work.

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a cutting device for nylon hot-melt wire processing.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] Preferably, the pressing plate is configured as an arc-shaped plate, and the arc-shaped opening end of the pressing plate faces downward.

[0008] Preferably, the distance between the two ends of the pressing plate is not less than the diameter of the fixing cylinder.

[0013] 1. The utility model drives the cutter to fall through the cylinder to cut the nylon hot fuse wire and drives the pressing plate to fall to press the nylon hot fuse wire, thereby preventing the nylon hot fuse wire from rebounding when the cutter cuts the nylon hot fuse wire;

[0014] 2. The utility model ensures that the height of the bottom of the pressure plate is lower than the height of the bottom of the cutter when the reset spring is in a normal state, and the height of the bottom of the pressure plate is higher than the height of the bottom of the cutter when the reset spring is fully contracted, thereby ensuring the stable cutting work;

[0015] 3. The arc-shaped pressing plate of the utility model reduces the contact area with the nylon hot-melt wire compared with a flat plate, thereby increasing the pressure and further improving the stability of the pressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0022] like Figure 1As shown in the figure, as a cutting device for processing nylon hot melt filaments of the present utility model, it includes a bearing table 1. The bearing table 1 is set in a U shape. A cylinder 2 is fixedly arranged at the inner top of the bearing table 1. The output end of the cylinder 2 is provided with a fixing plate 31. One side of the bottom of the fixing plate 31 is fixedly provided with a cutting knife 32. The other side of the bottom of the fixing plate 31 is fixed with a fixing cylinder 33. A telescopic rod 34 is slidably arranged in the fixing cylinder 33. The bottom of the telescopic rod 34 is fixed with a pressing plate 36. A return spring 35 is arranged between the pressing plate 36 and the fixing cylinder 33, and the return spring 35 is arranged around the outer side of the telescopic rod 34. By the operation of the cylinder 2, the cutting knife 32 is driven to fall to cut the nylon hot melt filament. At the same time, when the cylinder 2 operates to drive the cutting knife 32 to fall, it will also drive the pressing plate 36 to fall to press and fix the nylon hot melt filament, thereby preventing the nylon hot melt filament from rebounding when the cutting knife 32 cuts the nylon hot melt filament. By the return spring 35, it is ensured that the height of the bottom of the pressing plate 36 in the normal state is lower than the height of the bottom of the cutting knife 32, and the height of the bottom of the pressing plate 36 when the return spring 35 is completely contracted is higher than the height of the bottom of the cutting knife 32, ensuring the stable progress of the cutting work. Furthermore, the cutting mechanism 3 composed of the fixing plate 31, the cutting knife 32, the fixing cylinder 33, the telescopic rod 34, the return spring 35 and the pressing plate 36 avoids the rebound of the nylon hot melt filament generated during cutting while cutting the nylon hot melt filament, improving the practical value.

[0023] As Figure 1 shown, on both sides of the inner bottom of the bearing table 1, guiding and limiting members 4 are symmetrically arranged, and a gap for the nylon hot melt filament to pass through is left between the guiding and limiting members 4 and the bearing table 1. The nylon hot melt filament is guided and limited through the gap between the guiding and limiting members 4 and the bearing table 1, so that the nylon hot melt filament will not be loose, which is beneficial to the cutting work and also beneficial to the winding work. The pressing plate 36 and the guiding and limiting members 4 are both arc-shaped plate bodies made of plastic material. The plate bodies made of plastic material ensure that the pressing plate 36 and the guiding and limiting members 4 will not cause excessive wear to the nylon hot melt filament when contacting the nylon hot melt filament, thereby ensuring the quality of the nylon hot melt filament.

[0024] As Figure 2As shown, the pressure plate 36 is configured as an arc-shaped plate, and the arc-shaped opening end of the pressure plate 36 can face downward. Compared with a flat plate, the arc-shaped pressure plate 36 reduces the contact area with the nylon thermal fuse, thereby increasing the pressure and further improving the stability of the pressing. The spacing between the two ends of the pressure plate 36 is not less than the diameter of the fixed cylinder 33. The larger spacing allows the pressure plate 36 to press the nylon thermal fuse at two farther points on the nylon thermal fuse when pressing it, thereby improving the pressing effect. The arc-shaped opening end of the pressure plate 36 can also face upward. Compared with the opening end facing downward, the pressure plate 36 with the arc-shaped opening end facing upward changes the contact between two lines to one line, thereby further reducing the contact area between the pressure plate 36 and the nylon thermal fuse, thereby further increasing the pressure and further improving the stability of the pressing.

[0025] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
