[0002] The stenter is a commonly used textile machine in the process of cloth processing. It is used to flatten and stretch the cloth after padding, and finally dry and shape it. The stenter is used for cloth with wet heat plasticity, such as cotton, silk, wool, etc.

[0003] In the drafting process of the existing stenter setting machine, there are two types of cloth clamping structures. One is the cloth clip type, which is generally used for more precious fabrics, such as silk, and its clamping method is electromagnetic or spring type; the other is the pin type, which is to insert the needle plate into the edge of the cloth to achieve the positioning of the cloth. Both methods have relatively large defects. The pin type will leave pinholes on the cloth, affecting the product quality; the cloth clip type will often fall off when dealing with smoother cloth; and both methods are not easy to accurately position the cloth when dealing with curling on the edge of the cloth.

DETAILED DESCRIPTION

[0020] Combined with Figure 1-Figure 7 The aforementioned setting machine is convenient for setting the width of cloth; The invention comprises a tentering mechanism, wherein the tentering mechanism comprises two symmetrically arranged conveyor chains 10, the two conveyor chains 10 run in opposite directions, and the two conveyor chains 10 are used to transport cloth 50, and a plurality of clamping mechanisms 30 are evenly distributed on each conveyor chain 10, and the clamping mechanisms 30 run with the conveyor chains 10 to clamp and release the edges of the cloth 50; The clamping and releasing control of the cloth 50 by the clamping mechanism 30 can be used in conjunction with the drafting assembly to perform a tentering operation on the cloth 50. As mentioned in the background technology, the cloth clamping components in the prior art have the following two problems: First, it is not possible to achieve effective and stable clamping of different types of cloth, and the two existing clamping components each have their own clamping disadvantages; Secondly, when clamping cloth with warping problems, inaccurate positioning may occur.

[0021] Based on the above problem 2, the applicant optimized the clamping mechanism 30, specifically: The clamping mechanism 30 includes a clamping seat 16, a clamping base plate 31 is fixed at the bottom of the clamping seat 16, a lifting column 38 is slidably installed on the clamping seat 16, guide rods 11 slidably installed on the clamping seat 16 are provided on both sides of the lifting column 38, a first spring 39 is installed between the guide rod 11 and the clamping seat 16, a connecting head 14 is fixed on the top of the lifting column 38, a guide wheel 15 is rotatably installed on one side of the connecting head 14, the guide wheel 15 is matched and installed in the guide rail 40, the guide wheel 15 can move along the guide rail 40, a support block 35 is fixed at the bottom of the lifting column 38, the bottom of the support block 35 is inclined, a processing block 34 is arranged to fit the inclined surface of the bottom of the support block 35, an elastic structure is arranged between the processing block 34 and the support block 35, and the processing block 34 can fit the inclined surface of the support block 35 and move; Furthermore, the guide rail 40 is designed to be in the shape of a middle lifting rail 42 and clamping rails 41 on both sides, the lifting rail 42 is higher than the clamping rail 41, and the lifting rail 42 is smoothly connected to the clamping rail 41. When the guide wheel 15 moves along the guide rail 40 to the position of the clamping rail 41, the guide wheel 15 will move downward to drive the support block 35 and the processing block 34 to move downward. During the downward movement, the processing block 34 moves along the inclined surface of the support block 35, and the edge of the cloth 50 is clamped by the fit between the processing block 34 and the clamping bottom plate 31. The edge of the cloth 50 is flattened by the movement of the processing block 34 on the edge of the cloth 50, thereby ensuring that the clamping part is not affected by the warping of the cloth 50; when the guide wheel 15 is on the lifting rail 42, the clamping structure 30 releases the cloth 50; Furthermore, in order to optimize the warping treatment effect of the cloth 50, a receiving groove 24 is opened at the bottom of the processing block 34, and at least one roller 25 and at least one scraper 26 are installed in the processing block 34. The roller 25 is rotatably installed in the receiving groove 24. As the processing block 34 moves on the cloth 50, the roller 25 rotates to roll and smooth the edge of the cloth 50; the scraper 26 moves on the cloth 50 with the processing block 34 to scrape the edge of the cloth 50. Moreover, the roller 25 is closer to the edge of the cloth 50 than the scraper 26, so that the roller 25 can act on the cloth 50 first, and the scraper 26 can act on the cloth 50 later, thereby optimizing the processing effect on the edge of the cloth 50; In addition, the scraper 26 is designed to be rotatably arranged in the receiving groove 24, and a baffle 27 fixed in the receiving groove 24 is provided on one side of the scraper 26. The baffle 27 can restrict the rotation of the scraper 26 so that the scraper 26 can only rotate toward the roller 25. In this way, the scraper 26 will not act on the cloth 50 when it is reset, preventing the scraper 26 from messing up the cloth 50 when it is reset.

[0022] Based on the above-mentioned problem one, the applicant has opened at least one sliding groove 47 at the top of the storage groove 24, and a sliding piece 45 is slidably installed in the sliding groove 47. The bottom of the sliding piece 45 is jointly fixed on a locking seat 28, and is fixed between the locking seat 28 and the top wall of the storage groove 24 by a second spring 46. A number of locking heads 29 are evenly fixed at the bottom of the locking seat 28, and a number of locking holes 32 are evenly opened on the clamping base plate 31. The locking holes 32 match the shape of the locking heads 29, and the distribution of the locking holes 32 corresponds to that of the locking heads 29. A matching block 44 is also fixed on the locking seat 28, and one side of the matching block 44 is an inclined surface and is against the inclined surface of the push block 43, and the other side of the push block 43 is fixed to the processing block 34 is a middle plate 52 slidably connected, and a push plate 51 is fixed on one side of the middle plate 52. One side of the push plate 51 is also an inclined surface and extends out of the processing block 34. During the movement of the processing block 34 along the inclined surface of the support block 35, the support block 35 will push the push plate 51 into the processing block 34, thereby pushing the push block 43 to move, and the push block 43 will push the matching block 44 to descend, thereby driving the locking seat 28 to descend. When the locking seat 28 descends, the locking head 29 will drive part of the cloth 50 to sink into the locking hole 32 to form a clamping position, which greatly optimizes the clamping effect without causing damage to the cloth 50, and can conveniently and stably perform the width setting operation, greatly improving the width setting quality.

[0023] It should be noted that the locking head 29 may be made of soft rubber material to increase the friction force while minimizing the damage to the cloth 50 as much as possible.

[0024] The elastic structure includes a fixed head 23 fixed to the processing block 34, the fixed head 23 is fixed to the slide 22, the slide 22 is slidably installed in a slide 21 opened on the vertical bar 18, the slide 22 and the slide 21 are fixed by a third spring 19, the vertical bar 18 is slidably set on at least two cross bars 37, the cross bars 37 are connected to the vertical bar 18 by a fourth spring 17, and the cross bars 37 are fixed between the two fixed plates 36, and the fixed plates 36 are fixed to the support block 35.
