When external force acts on the movable side pressure block, the guide mechanism is used to axially move the movable side pressure block along the length direction of the central axis, and the gap between the movable side pressure block and the positive side surface of the fixed side pressure block will change. The positioning mechanism is used to position the movable side pressure block and the shell, so that after the movable side pressure block is adjusted into place, the gap between it and the two positive side surfaces of the fixed side pressure block will not change due to the friction between the yarn and it.

[0006] With the above-mentioned design, when external force acts on the movable side clamping block, the guide mechanism is used to change the width of the extended section of the movable side clamping block, thereby changing the gap between the front side of the movable side clamping block and the fixed side clamping block, thereby effectively solving the problem of limited wire diameter groove size that can be provided by traditional yarn filters, thereby improving operational production efficiency; moreover, the positioning mechanism is used to fix the movable side clamping block after it is adjusted into place, thereby preventing the gap between the front sides of the two clamping blocks from changing due to friction between the yarn and the clamping block.

[0007] Furthermore, the guiding mechanism is that an oblique convex strip is provided in the inner cavity of the shell, the angle between the oblique convex strip and the central axis is α, and the movable side clamping block is provided with a sliding groove adapted to the oblique convex strip, and the angle between the sliding groove and the central axis is α. The clamping block is driven up and down along the oblique convex strip by external force to change the width of the protruding section of the movable side clamping block, thereby changing the gap between the front sides of the two clamping blocks.

[0008] Furthermore, the yarn filter device further includes at least one actuator, which is partially disposed on the outer end surface of the housing and is associated with the movable side clamping block in motion, and is driven by an external force to reciprocate in a direction parallel to the oblique convex strip, thereby driving the movable side clamping block to move up and down along the oblique convex strip. The arrangement of the actuator facilitates the adjustment of the movable side clamping block to move up and down relative to the housing.

[0009] Furthermore, a guide groove is formed in the inner cavity of the shell on a side away from the central axis, the guide groove and the oblique convex strip are parallel to each other, the actuator has a slider matched with the guide groove, the slider of the actuator moves back and forth along the guide groove, thereby driving the movable side clamping block to move up and down along the oblique convex strip; the actuator is provided with a clamping block on the inner end face close to the slider, and the movable side clamping block is provided with a clamping groove matched with the clamping block, and the linkage between the actuator and the movable side clamping block is realized by the clamping fit between the clamping block and the clamping groove. The guide groove is arranged in parallel with the oblique convex strip, so that when the movable side clamping block moves up and down, the clamping block of the actuator is not easy to be separated from the clamping groove of the clamping block.

[0010] Furthermore, the actuator has a connecting portion and a hand-pushing portion on the outer end near the slider from the inside to the outside; the outer side of the shell has a guide bar, the guide bar is parallel to the oblique convex bar, and the guide bar is provided with a clearance groove; the connecting portion of the actuator is placed in the clearance groove, and when the slider of the actuator moves back and forth along the guide groove, the connecting portion can move up and down in the clearance groove, and the hand-pushing portion of the actuator can move up and down along the outer end surface of the guide bar; the positioning mechanism is that the outer end surface of the guide bar is provided with at least two grooves, and the hand-pushing portion of the actuator is provided with a convex point on one side of the groove.

[0011] Furthermore, the back of the housing is provided with scale marks at each groove, so that the user can easily read the numerical value of the wire diameter groove width.

[0012] In order to achieve the above-mentioned purpose, the present invention discloses another embodiment of a yarn feeder filter device, in which the fixed side clamping block is eliminated and two movable side clamping blocks are mirror-arranged in the inner cavity of the shell along the central axis, so that the two clamping blocks can be movably connected relative to the shell.

[0013] Furthermore, the pressing block is made of ceramic material at least on the front side surface. The ceramic material has good wear resistance, which reduces the wear caused by friction between the yarn and the front side surface of the pressing block.

[0014] Furthermore, the filter yarn device is fixed on the frame, and is located between the two pressing block areas and the horizontal plane to form a downward inclined angle α, and the value range of the angle α is 5°~15°. Through the above setting, it is more conducive to the cotton wool filtered by the two pressing blocks to slide downward along the downward inclined slope of the two pressing blocks, so that the above cotton wool is not conducive to accumulation above the pressing blocks.

In the present embodiment, the entire clamping block 2 is made of ceramic material. The two clamping blocks 2 disclosed in the present embodiment are both provided with a positioning mechanism 3 and a guiding mechanism 4 between the shell 1, so that the two clamping blocks 2 can be movably connected with the shell 1. The clamping block 2 is defined as a movable side clamping block 2. The guiding mechanism 4 is that an oblique convex strip 41 is provided in the inner cavity of the shell 1. The angle between the oblique convex strip 41 and the central axis L is α. The movable side clamping block 2 is provided with a slide groove 42 adapted to the oblique convex strip 41. The movable side clamping block 2 is driven by an external force to move up and down along the oblique convex strip 41 to change the width W of the extended section 21 of the movable side clamping block 2, thereby changing the gap S between the positive side surfaces 211 of the two clamping blocks 2. Please refer to Figure 4 and Figure 5Preferably, a guide groove 12 is formed in the inner cavity of the shell 1 on a side away from the central axis L, and the outer side of the shell 1 has a guide strip 13, and the guide strip 13 is provided with a clearance groove 131, and the guide groove 12 and the guide strip 13 are parallel to the oblique convex strip 41. The actuator 5 is partially arranged on the outer end surface of the shell 1 and is linked with the movable side clamping block 2. The actuator 5 has a slider 51 adapted to the guide groove 12, and the actuator 5 is provided with a clamping block 52 on the inner end surface close to the slider 51, and the movable side clamping block 2 is provided with a clamping groove adapted to the clamping block 52 22, the engagement of the engaging member 5 and the movable side clamping block 2 is realized by the engagement of the engaging block 52 and the engaging groove 22. When the slider 51 of the engaging member 5 is driven to reciprocate along the guide groove 12 of the housing 1 by an external force, the movable side clamping block 2 is then driven to move up and down along the oblique convex strip 41. Moreover, the guiding groove 12 is arranged in parallel with the oblique convex strip 41, so that when the movable side clamping block 2 moves up and down, the engaging block 52 of the engaging member 5 is not easy to be separated from the engaging groove 22 of the clamping block 2. The engaging member 5 has a connecting portion 53 and a hand-pushing portion 54 from the inside to the outside on the outer end close to the slider 52. The connecting portion 53 of the movable member 5 is placed in the giving way groove 131, and when the slider 52 of the movable member 5 reciprocates along the guide groove 12, the connecting portion 53 can move up and down in the giving way groove 131, and at the same time, the hand-pushing portion 54 of the movable member 5 can move up and down along the outer end surface of the guide strip 13; the positioning mechanism 3 is used to locate the position between the movable side clamping block 2 and the shell 1, so that the movable side clamping block 2 after being adjusted into place will not cause the gap S between it and the two positive side surfaces 211 of the fixed side clamping block 2 to change due to the friction between the yarn and it, and the positioning mechanism 3 is between the movable side clamping block 2 and the shell 1 Several snap-fitting parts are arranged between them. In this embodiment, the snap-fitting parts are that the outer end face of the guide strip 13 is provided with at least two grooves 32, and the hand-pushing part 54 of the actuator 5 is provided with a protrusion 31 on one side relative to the groove 32. The protrusion 31 of the actuator 5 is switched between the grooves 32 to adjust the position of the movable side clamping block 2, thereby achieving the fixation of the gap S between the front side surfaces 211 of the two clamping blocks 2; preferably, the back of the shell 1 is provided with a scale mark K at each groove 32, so that the user can easily read the value of the width of the wire diameter groove S.

[0019] With the above-mentioned design, when external force acts on the movable side clamping block 2, the cooperation between the oblique convex strip 41 and the slide groove 42 makes the movable side clamping block 2 move up and down relative to the shell 1, thereby changing the width of the protruding section 21 of the movable side clamping block 2, and then changing the gap S between the front side surfaces 211 of the two clamping blocks 2 to adapt to yarns of different wire diameters, which well solves the problem of limited wire diameter groove size that traditional yarn filters can provide, thereby improving operational production efficiency; moreover, through the positioning mechanism 3, the movable side clamping block 2 can be fixed after being adjusted into place, and the gap S between the front side surfaces 211 of the two clamping blocks 2 will not change due to the friction between the yarn and it.

[0020] It should be noted that if one of the movable side clamping blocks 2 is replaced by one fixed in the inner cavity of the shell, that is, the positioning mechanism 3 and the guide mechanism 4 do not need to be configured for the clamping block, and the side clamping block can be defined as a fixed side clamping block. By moving the movable side clamping block 2 up and down on one side while the fixed side clamping block remains stationary, the change of the gap S between the movable side clamping block and the front side of the fixed side clamping block can also be achieved, but the range of gap adjustment is smaller than the adjustable range when both clamping blocks are configured as movable side clamping blocks.

[0021] A more preferred design is that the yarn filter device 100 is fixed on the frame 1000, and the yarn filter device 100 forms a downward inclined angle α between the two pressing block areas and the horizontal plane, and the value range of the angle α is 5°~15°. Through the above arrangement, it is more conducive to the cotton wool filtered by the two pressing blocks 2 to slide downward along the downward slope of the two pressing blocks 2, so that the above cotton wool is not conducive to accumulation above the pressing blocks.

[0022] The above embodiments and illustrations do not limit the product form and style of the present invention. Any appropriate changes and modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
