Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a yarn clearer cutting mechanism with high stability. Background Art

[0002] The yarn clearer can cut off the defective yarn that exceeds the set thickness or length, and remove the yarn defects that affect the product quality. In the photoelectric electronic yarn clearer, the working principle of the cutting mechanism is more complicated. This type of yarn clearer detects the geometric quantity of the yarn defect shape through a sensor and converts it into a corresponding electrical pulse signal for yarn defect detection. Once the yarn defect is detected, the cutting mechanism will respond quickly and accurately cut off the defect.

[0003] The surface of the yarn itself may be contaminated with lint, and the yarn diameter becomes thicker, which makes it easy for the yarn clearer to misjudge and lead to unnecessary cutting. Therefore, the cutting mechanism needs to be optimized. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a yarn clearer cutting mechanism with high stability, comprising a base plate 1 and a yarn clearer body 2 fixed on the base plate 1, two groups of symmetrical cutting mechanisms 3 are arranged on the front side of the base plate 1, and the two groups of cutting mechanisms 3 are respectively located on the upper and lower sides of the yarn clearer body 2, wherein the cutting mechanisms 3 on the upper and lower sides both include a sheet metal layer 31 and a cutting frame 32 sliding along the sheet metal layer 31.

[0025] The sheet metal layer 31 is fixedly mounted on the base plate 1, a longitudinal sliding opening 311 is provided on the front side of the sheet metal layer 31, an operation opening 312 is provided on the front end of the sheet metal layer 31, and a longitudinal sliding channel 313 is provided on the inner wall of the sheet metal layer 31;

[0026] A matching channel 321 is provided on the front side of the cutting frame 32, and the matching channel 321 cooperates with the longitudinal slide channel 313. A fastening bolt 322 is also fixed to the front side of the cutting frame 32, and the fastening bolt 322 extends from the longitudinal slide port 311. The position of the cutting frame 32 can be limited by the fastening bolt 322. The fastening bolt 322 is tightened by a nut to limit the fastening bolt 322, so that the position of the cutting frame 32 is restricted to prevent the cutting frame 32 from moving. At the same time, it is also convenient to adjust the position of the cutting frame 32 and control the length of the yarn to be cut.

[0027] The two groups of cutting frames 32 are both provided with inner cutting units 33, and the inner cutting units 33 include two groups of symmetrically arranged supporting cylinders 331 and blades 333 for cutting. The supporting cylinders 331 are electrically connected to the yarn clearer body 2. When the yarn clearer body 2 detects the position of the defect, the supporting cylinders 331 can be controlled to shrink, which is convenient for control.

[0028] Two groups of supporting cylinders 331 are respectively embedded in the inside of the two sides of the cutting frame 32. An extension shaft 332 is fixed to the output end of the supporting cylinder 331. The end of the extension shaft 332 is fixed to the blade 333. The blades 333 on both sides can cut the yarn under the action of the supporting cylinder 331. The blades 333 on both sides can cut the yarn.

[0029] A support plate 334 is fixed to the lower end of the extension shaft 332, and both sides of the support plate 334 are integrally formed with a clamping edge 335 extending to both sides. A support frame 336 is provided at the lower end of the support plate 334 and is clamped by the clamping edge 335. A return spring 337 is fixed inside the support frame 336. A rubber layer 338 for extrusion is also attached to the outer side of the support frame 336. The rubber layer 338 is located on the outer side of the blade 333. The rubber layers 338 on both sides are first squeezed against each other and then squeezed against the blades 333 on both sides. The rubber layers 338 at the ends of the support frame 336 can approach each other during the movement of the blade 333, and the rubber layers 338 on both sides can approach each other, so that the rubber layer 338 can squeeze the yarn to achieve control.

[0030] A cleaning frame 34 is also provided in the cutting frame 32 at the lower end. The cleaning frame 34 includes a cylinder 341 and a support rod 342. The cylinder 341 is located in the cleaning frame 34. Two support rods 342 are provided. The two support rods 342 are respectively fixed to the outer sides of the cylinder 341, and the ends of the support rods 342 are fixed to the cleaning frame 34.

[0031] The upper and lower sides of the cylinder 341 are provided with arc-shaped edges 343, and the outer side of the arc-shaped edges 343 is also integrally formed with a connecting end 344, which is fixed to the end surface of the cylinder 341, and an elastic band 345 is clamped on the connecting end 344. The elastic band 345 is squeezed by the yarn passing through, and the elastic band 345 is sleeved on the connecting end 344. The outer side is blocked by the arc-shaped edges 343, which can prevent the elastic band 345 from falling off and facilitate the removal of the elastic band 345.

[0032] The inner side of the elastic band 345 is a flat rubber band, and the flat surface can contact the yarn to prevent the elastic band 345 from rotating.

[0033] When in use, the yarn extends upward from the cylinder 341 at the lower end, passes through the inner cutting unit 33 at the lower end, and the yarn clearer body 2, and then passes through the inner cutting unit 33 at the upper end. When the yarn clearer body 2 detects that the yarn has defects, the support cylinder 331 in the inner cutting unit 33 is driven to extend outward, so that the blades 333 on both sides are squeezed to cut the yarn;

[0034] When the supporting cylinder 331 pushes outward, the rubber layers 338 on both sides are also driven to approach each other and clamp the yarn first. Then the return spring 337 is stretched to squeeze the blades 333 on both sides. After the yarn breaks, the thread end is clamped, which is convenient for operation.

[0035] Secondly, by using an elastic band 345 to bind the connecting end 344, the elastic band 345 is horizontally positioned on the upper and lower sides of the cylinder 341. After the yarn passes through the cylinder 341, the yarn and the elastic band 345 are squeezed, and the fluff on the yarn contacts the elastic band 345 and gets stuck, thereby preventing the yarn from being misdetected. At the same time, the arc edge 343 and the connecting end 344 are set, so that the elastic band 345 can be directly installed and removed, and the fluff on the elastic band 345 can be cleaned.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
