Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, specifically to a yarn clamping device for an air-jet loom for polyester / viscose fabric. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The working principle utilizes air as the weft insertion medium; the compressed airflow generates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion. The yarn clamp is an important component of the air-jet loom. During the weft insertion process, the yarn clamp intermittently clamps the fabric, providing tension and preventing untwisting. Once the yarn clamp is fixed to the air-jet loom, adjusting the clamping plates requires removing and re-fixing the yarn clamp, which is time-consuming and labor-intensive. Therefore, a yarn clamp for polyester / viscose fabric air-jet looms is proposed to facilitate adjustment of the clamping plate position. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a yarn clamp for an air-jet loom for polyester / viscose fabric.

[0004] The technical solution adopted by this utility model to solve its technical problem is a yarn clamping device for a polyester-viscose fabric air-jet loom, including a support. A first hydraulic cylinder and a second hydraulic cylinder are fixed to the top of the support. A clamping seat is fixed to the bottom end of the piston rod of the first hydraulic cylinder, and a clamping plate is fixed to the bottom end of the piston rod of the second hydraulic cylinder. A protrusion is integrally formed on one side of the support located on the clamping plate. Anti-slip pads are fixed to the sidewalls of the clamping plate and the protrusion facing each other. A groove is opened on the side of the clamping seat away from the support, and a clamping seat is provided in the groove. Limiting bolts are provided on both sides of the clamping seat, and screw holes adapted to the limiting bolts are opened on both sides of the clamping seat. The ends of the two limiting bolts abut against the clamping seat. An electric push rod is fixed to the top of the clamping seat, and a clamping plate is fixed to the bottom end of the piston rod of the electric push rod.

[0005] By adopting the above technical solution, the piston rod of the second hydraulic cylinder drives the clamping plate to move down, and the two anti-slip pads are in close contact with the air-jet loom, which facilitates the overall fixation. The piston rod of the first hydraulic cylinder drives the clamping seat to move vertically, pulls out the clamping seat and tightens the two limit bolts, which can adjust the distance between the clamping seat and the support, thereby facilitating the adjustment of the position of the clamping plate as needed, saving time and effort.

[0006] Specifically, vertical rods are fixed at the four corners of the top of the card plate, and the tops of the four vertical rods all pass through the support.

[0007] By adopting the above technical solution, the stability of the clamping plate can be improved by setting up the vertical rod.

[0008] Specifically, the top of the card holder is fixed with two vertical plates, and the top of both vertical plates passes through the support.

[0009] By adopting the above technical solution, the vertical plate design can improve the stability of the card holder.

[0010] Specifically, two guide plates are fixed to the top of the clamping plate, and the tops of the two guide plates penetrate the clamping seat.

[0011] By adopting the above technical solution, the stability of the clamping plate can be improved by setting the guide plate.

[0012] Specifically, the clamp is provided with two connecting plates, and protective pads are fixed to the side walls of the two connecting plates facing each other.

[0013] By adopting the above technical solution, the protective pad can protect the fabric.

[0014] Specifically, each of the two opposing sidewalls of the connecting plates is integrally formed with a locking block. The inner bottom wall of the clamping seat and the bottom end of the clamping plate are provided with a locking groove that matches the locking block. The top end of the clamping plate and the bottom end of the clamping seat are fixed with a stop block. Connecting rods are provided above and below the clamping plate. Each of the two stop blocks has two through holes for the ends of the connecting rods to pass through. Each of the two connecting rods is fitted with two springs. Insert blocks are fixed to the opposing ends of the two connecting rods. Slots that match the insert blocks are provided on each of the two locking blocks.

[0015] By adopting the above technical solution, pulling the two connecting rods causes the two inserts to move in opposite directions, and the ends of the two inserts disengage from the two locking blocks. Pulling out the two connecting plates allows the two connecting plates, along with the protective pads, to be removed for cleaning or replacement.

[0016] The beneficial effects of this utility model are:

[0017] The present invention relates to a yarn clamping device for a polyester / viscose fabric air-jet loom. The piston rod of the second hydraulic cylinder drives the clamping plate to move downward, and two anti-slip pads are pressed tightly against the air-jet loom for easy overall fixation. The piston rod of the first hydraulic cylinder drives the clamping seat to move vertically, pulls out the clamping seat and tightens the two limit bolts, which can adjust the distance between the clamping seat and the support, thereby facilitating the adjustment of the position of the clamping plate as needed, saving time and effort.

[0018] The present invention relates to a yarn clamping device for a polyester / viscose fabric air-jet loom. By pulling two connecting rods, two insert blocks move in opposite directions, and the ends of the two insert blocks disengage from two locking blocks. By pulling out the two connecting plates, the two connecting plates, along with the protective pads, can be removed for cleaning or replacement. Attached Figure Description

[0026] In use, the piston rod of the second hydraulic cylinder 10 drives the clamping plate 12 to move down, and the two anti-slip pads 13 are in close contact with the air-jet loom for easy overall fixation. The piston rod of the first hydraulic cylinder 9 drives the clamping seat 2 to move vertically, pull out the clamping seat 5 and tighten the two limit bolts 7, which can adjust the distance between the clamping seat 5 and the support 1, thereby facilitating the adjustment of the position of the clamping plate 6 as needed, saving time and effort. The piston rod of the electric push rod 3 drives the clamping plate 6 to move down, which can clamp the fabric.

[0027] To improve the stability of the cardboard 12, for example, such as Figure 1 As shown, vertical rods 11 are welded and fixed at the four corners of the top of the card plate 12, and the tops of the four vertical rods 11 all pass through the support 1.

[0028] During use, the piston rod of the second hydraulic cylinder 10 drives the clamping plate 12 to move downward, and the vertical rod 11 moves downward accordingly, which improves the stability of the clamping plate 12.
