DETAILED DESCRIPTION

[0019] It should be noted that the embodiments in the present embodiment and the features in the embodiments can be combined with each other without conflict, and the technical solutions in the present embodiment will be clearly and completely described below with reference to the drawings in the present embodiment. Obviously, the described embodiments are only part of the embodiments of the present embodiment, not all the embodiments. Based on the embodiments in the present embodiment, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present embodiment.

[0020] Referring to Figures 1-5 The utility model discloses an extrusion fixing mechanism's structure schematic view.

[0021] The extrusion fixing mechanism comprises a support plate 12, a first sliding groove 13 is formed through the surface of the support plate 12, a plurality of first sliding blocks 14 are arranged in the first sliding groove 13, a first compression spring 17 is fixedly installed on the lower surface of the first sliding block 14, one end of the first compression spring 17 is fixedly installed with a limiting block 18, cloth can be wound on the reel 9 arranged in the gap, the limiting block 18 on the extrusion fixing mechanism can compress and limit the cloth wound on the reel 9, and when the wound cloth becomes thicker and thicker, the limiting block 18 can slide upward along with the first compression spring 17, and the first compression spring 17 is compressed under stress, so that the cloth is extruded and limited throughout the winding process to prevent slipping.

[0022] It should be noted that the first slider 14 is provided with at least three, linearly equidistant arrangement, the first slider 14 at both ends is fixed in the first sliding groove 13, the rest of the first slider 14 is slidingly arranged in the first sliding groove 13, and the second compression spring 27 is connected between the two adjacent first sliders 14. The existence of the second compression spring 27 can provide the first sliders 14 at both ends with opposite elastic force, so as to make the two first sliders 14 move away from each other, thereby making the two limit blocks 18 move away from each other. Since the limit blocks 18 are pressed and contacted on the surface of the cloth, the advantage of this arrangement is that the limit blocks 18 can be used to stretch the surface to avoid the phenomenon of gathering wrinkles in the rolling process due to the softness of the cloth. Because, as long as the cloth appears part of the gathering wrinkles, it will inevitably drive the limit block 18 in contact with it to move, and due to the existence of the second compression spring 27, the adjacent two limit blocks 18 are pushed away from each other, thereby smoothing the gathering wrinkles, and better ensuring the stretchability of the cloth.

[0023] Secondly, the first pulling shaft 6 and the second pulling shaft 7 are fixedly sleeved with an electrostatic layer 8 on the surface, and the electrostatic layer 8 is used for adsorbing the lint and dust on the surface of the cloth. In the production process of cloth pulling and winding, the surface of the cloth will adhere to dust and lint, thereby affecting the production quality of the cloth. The setting of the electrostatic layer 8 can avoid this situation.

[0024] Secondly, a plurality of annular anti-skid ribs 10 are fixedly installed on the surface of the reel 9, and the annular anti-skid ribs 10 are made of rubber material. The rubber material has good elasticity and friction coefficient. The setting of the annular anti-skid ribs 10 can increase the friction force between the cloth and the surface of the reel 9, and further avoid the cloth from slipping off the reel 9.

[0025] Secondly, the slide plate 16 and the first support plate 15 are provided with two symmetrical limit grooves 11 on the side wall, and the both ends of the support plate 12 are slidingly installed in the two limit grooves 11. The support plate 12 is fixedly installed in the limit groove 11 by the positioning bolt. A second slider 20 is fixedly arranged below the limit groove 11 on the side wall of the slide plate 16. A second sliding groove is formed on the side wall of the base 1, and the second slider 20 is slidingly installed in the second sliding groove. A plurality of second bolts 26 are threadedly installed on the surface of the base 1. A through hole is formed on the surface of the second slider 20 and matched with the second bolt 26. One end of the second bolt 26 penetrates the through hole and is threadedly connected with the bottom of the second sliding groove. The slide plate 16 is inserted into the base 1 along the second sliding groove, and then the second bolts 26 are rotated to fix the second slider 20 in the second sliding groove, so as to fix the slide plate 16 on the base 1. When the cloth is wound into a cloth, the slide plate 16 can be taken down along the second sliding groove, and the wound cloth on the reel 9 can be taken out.

[0026] Finally, the first fixed block 2 is fixedly installed on the side wall of the base 1, the first motor 3 is fixedly installed on the first fixed block 2, the output shaft of the first motor 3 penetrates and is rotatably installed on the base 1, and the output shaft is coaxially connected with the second pulling shaft 7, the second fixed block 4 is fixedly installed on the side wall of the base 1, the second motor 5 is fixedly installed on the second fixed block 4, the rotating sleeve 22 is fixedly installed on the side wall of the sliding plate 16, one end of the winding shaft 9 is rotatably installed in the rotating sleeve 22, the output shaft of the second motor 5 penetrates the first supporting plate 15 and the rotating sleeve 22, the first flange 23 is fixedly installed on the output shaft of the second motor 5, the second flange 24 is fixedly installed on one end of the winding shaft 9, a plurality of first bolts 25 are fixedly connected between the first flange 23 and the second flange 24, one end of the winding shaft 9 is fixedly connected with the output shaft of the second motor 5 through the first flange 23 and the second flange 24, and the first motor 3 and the second motor 5 are arranged to be started, so that the second pulling shaft 7 and the winding shaft 9 are driven to rotate, the cloth can be placed between the gaps between the two symmetrical pulling shafts and wound on the winding shaft 9, and the winding cloth on the winding shaft 9 gradually thickens with the winding time, and the limiting block 18 is always in close contact with the winding cloth, so that the problem of scattered winding cloth caused by sudden stop can be prevented.

[0027] When the cloth needs to be pulled and wound, one end of the winding shaft 9 is rotatably installed in the rotating sleeve 22, the second sliding block 20 of the sliding plate 16 is slidably inserted into the base 1 along the second sliding groove, the other end of the winding shaft 9 is fixedly connected with the output shaft of the second motor 5 through the first flange 23 and the second flange 24, then the second bolts 26 are rotated to make one end of the second bolts 26 abut against and fix the upper surface of the second sliding block 20 in the second sliding groove, so that the sliding plate 16 is fixed, then the first motor 3 and the second motor 5 are started to drive the second pulling shaft 7 and the winding shaft 9 to rotate, the cloth is placed between the gaps between the two symmetrical pulling shafts, and then wound on the rotating winding shaft 9, then the extrusion fixing mechanism is slidably installed along the limiting groove 11 of the sliding plate 16 and the first supporting plate 15, a plurality of limiting blocks 18 on the extrusion fixing mechanism extrude and limit the cloth, when the cloth is wound thicker and thicker on the winding shaft 9, the extrusion fixing mechanism also slides and rises in the limiting groove 11, so that the cloth is always in the extruded and limited state during the winding process, when the cloth winding is completed, the first flange 23 and the second flange 24 are removed, the output shaft of the second motor 5 and the winding shaft 9 are separated, the sliding plate 16 is slid along the second sliding groove in the side wall of the base 1 and taken out, and the winding shaft 9 is removed, and the cloth wound on the winding shaft 9 can be conveniently taken out.
