Description

Linked Yarn Cutter for Textile Machinery

Technical field:

The invention relates to the technical field of yarn cutters, in particular to a yarn cutter used in a textile machine.

Background technique:

During the working process of textile machinery, it is sometimes necessary to cut off the yarn on the spindle to change the spindle. As shown in Figure 1, the cutting knife A1 and the thread pressing block A2 of the existing yarn cutter are all fixed on the cutting rod A3, which is a telescopic rod that moves in the horizontal direction. When the yarn needs to be cut, the cutting rod A3 The bar A3 moves to the right, the yarn is cut off, and the yarn is pushed down by the thread-pressing block A2, so that the operator finds the yarn end at the thread-pressing block A2 and operates next time. Its shortcomings are: 1. Since the cutter A1 and the crimping block A2 are all fixed on the cutting rod A3, the cutter is generally made of metal or alloy materials, and the crimping block is generally made of plastic materials. It is required that the right ends of the cutter A1 and the thread pressing block A2 be substantially on the same plane, so that when the cutter cuts the yarn, the thread pressing block A2 also presses the yarn, that is to say, its assembly requirements are high. 2. After the yarn cutter works for a period of time, the cutter A1 and the thread pressing block A2 will inevitably wear out, so that the thread pressing block cannot press the yarn or the cutter cannot cut the yarn. This is mainly because Since the worn cutter A1 and the right end face of the thread pressing block A2 are not on the same plane, when cutting the yarn, the thread pressing block presses the yarn and cuts the yarn at the same time, if the right end face of the thread pressing block A2 If the right end face of the cutter A1 is lower than the right end face of the cutter A1, the thread pressing block cannot press the yarn. If the right end face of the cutter is lower than the right end face of the thread pressing block, the thread pressing block presses the yarn, and the cutter Can't cut yarn.

Invention content:

The object of the present invention is to address the deficiencies of the prior art, and provide an interlocking yarn cutter for textile machinery, which can ensure that the thread pressing block also presses the yarn when the yarn cutter cuts the yarn.

Technical solutions of the present invention are as follows:

A linked yarn cutter for textile machinery, including a yarn cutter housing and a cutting rod of the yarn cutter, a cutter is fixed on the cutting rod, a cutter pad and a thread pressing pad are fixed on the yarn cutter housing, The knife is facing the cutter pad, and a briquetting base is fixed on the yarn cutter housing, and the briquetting base is screwed and fixed together with the cylinder, and a chute is formed on the cylinder, and a base guide column is formed on the briquetting base , the slider is inserted into the cylinder and inserted into the base guide post of the press block base;

The pressure block is "convex" shape, the pressure block is inserted into the cylinder body and the front end of the pressure block is exposed from the front hole of the cylinder body, the lower end of the compression spring is fixed on the slider, the upper end faces the lower part of the pressure block, and the slider A sliding column is formed on the top, and the sliding column is inserted into the chute, and one end of the linkage plate is fixed on the cutting rod, and the other end is fixed on the sliding column.

One end of the linkage plate is fixed on the cutting rod by a screw, the other end is fixed on the sliding post by a screw, and a pressing block base is fixed on the yarn cutter housing by a screw.

The beneficial effects of the present invention are:

It can ensure that when the cutter cuts the yarn, the pressing block also presses the yarn, and the yarn does not fall from the pressing block at the same time.

detailed description:

Embodiment: As shown in Figures 2 to 4, the interlocking yarn cutter for textile machinery includes a yarn cutter housing 1 and a cutting rod 2 of the yarn cutter, a cutter 3 is fixed on the cutting rod 2, and the yarn cutter housing The body 1 is fixed with a cutter pad 4 and a thread pressing pad 5, the cutter 3 faces the cutter pad 4, and a briquetting base 6 is fixed on the yarn cutter housing 1, and the briquetting base 6 is connected with the barrel 7 are screwed and fixed together, a chute 71 is formed on the cylinder body 7, a base guide post 61 is formed on the briquetting base 6, and the slider 10 is inserted into the cylinder 7 and inserted into the base guide of the briquetting base 6. on column 61;

The pressure block 9 is "convex" shape, the pressure block 9 is inserted in the cylinder body 7 and the front end of the pressure block is exposed from the front end hole 72 of the cylinder body 7, the lower end of the compression spring 11 is fixed on the slider 10, and the upper end faces the The bottom of the briquetting block 9 forms a sliding column 101 on the sliding block 10, and the sliding column 101 is inserted in the chute 71. One end of the link plate 8 is fixed on the cutting bar 2, and the other end is fixed on the sliding column 101.

One end of the linkage plate 8 is fixed on the cutting rod 2 by screws, and the other end is fixed on the sliding column 101 by screws, and the pressing block base 6 is fixed on the yarn cutter housing 1 by screws.

Working principle: When the cutting rod 2 moves to the right under the elastic force of the cutting rod driving spring 12, it drives the linkage plate 8 and the slider 10 to move to the right together. When the cutter 3 touches the cutter pad 4, the yarn is cut off, the clip spring 11 pushes the pressing block 9 to stretch out to the right and presses the cut yarn on the thread pressing pad 5, because the pressing block 9 presses the yarn under the elastic force of the clip spring 11, so it will not The yarn cannot be pressed, and the pressed yarn will not fall off. When the present invention is designed, when the bottom of the briquetting block 9 presses the upper end of the base guide post 61, it is ensured that the front end of the briquetting block 9 is still exposed from the front end hole 72. That is to say, the maximum gap between the pressing block 9 and the upper end of the base guide post 61 does not exceed the height H of the upper portion of the pressing block 9 .

The present invention does not affect the normal extension and manual pull-back of the cutting rod 2 of the yarn cutter, because when the cutting rod 2 moves linearly, the slider 10 also moves together with the cutting rod 2 under the drive of the linkage plate 8 .
