DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 13 A carpet edge pulling and wrinkle prevention device for carpet production, comprising a workbench 1, legs 2 and a heat setting plate 3, wherein the legs 2 are arranged at the four corners below the workbench 1, and further comprising:

[0042] A clamping assembly, the clamping assembly includes a support rod 4, a slider 5, a lifting frame 6, a threaded rod 7, a pressing plate 8 and a handle 9. The four corners of the workbench 1 are provided with sliding holes flush with the diagonal lines, the support rod 4 is provided in the sliding hole, the slider 5 is slidably connected with the sliding hole, the support rod 4 passes through the slider 5, the lifting frame 6 is provided at one end of the slider 5 away from the center of the workbench 1, and a lifting groove is provided at one end of the lifting frame 6 close to the center of the workbench 1, the threaded rod 7 is rotatably provided in the lifting groove, the upper part of the threaded rod 7 passes through the lifting frame 6 and is connected to the handle 9, the pressing plate 8 is T-shaped, and one end of the pressing plate 8 extends into the lifting groove and is threadedly connected to the threaded rod 7;

[0043] The legs 2 provide stable support for the workbench 1, and the workbench 1 provides stable support for the support rod 4. The slider 5 is slidably connected to the slide hole and the support rod 4 passes through the slider 5, so that the slider 5 can move in the slide hole along the direction of the support rod 4. When the carpet needs to be clamped, the position of the slider 5 on the workbench 1 is first adjusted according to the size of the carpet, the edge of the carpet is placed on the upper part of the slider 5, and the handle 9 is turned to drive the threaded rod 7 in the lifting frame 6 to rotate. Since one end of the pressing plate 8 extends into the lifting slot and is threadedly connected to the threaded rod 7, the rotation of the threaded rod 7 causes the pressing plate 8 to move axially along the threaded rod 7, pressing the edge of the carpet downward to achieve fixed clamping of the edge of the carpet.

[0044] A lifting assembly, the lifting assembly includes a bracket 10, a top plate 11, a lifter 12 and a lifting plate 13. The brackets 10 are arranged at the four corners above the workbench 1, and the top plates 11 are arranged on four groups of the brackets 10. The output end of the lifter 12 passes through the top plate 11 and is connected to the lifting plate 13. The heat setting plate 3 is arranged below the lifting plate 13. The four corners of the lifting plate 13 are also provided with notches adapted to the clamping assembly;

[0045] The brackets 10 at the four corners above the workbench 1 support the top plate 11, and the output end of the lifter 12 passes through the top plate 11 and is connected to the lifter 13. When the carpet needs to be heat-set and the middle wrinkles need to be smoothed, the lifter 12 is started to control the lifter 13 to move up and down, and the heat-setting plate 3 is set below the lifter 13. As the lifter 13 descends, the heat-setting plate 3 contacts the surface of the carpet. At this time, in conjunction with the clamping assembly stretching the edge of the carpet, the heat-setting plate 3 applies pressure and heat to the carpet as a whole, so that the fibers in the middle part of the carpet are rearranged under the action of heat and force, thereby effectively smoothing wrinkles caused by uneven distribution of raw materials, uneven pressure of production equipment, etc.

[0046] It should be noted that the heat setting plate 3 starts working only after the lifting plate 13 moves to the specified position. It can be controlled by a travel switch, a controller button or a timing control. This can save energy and avoid the risk of burns caused by accidental contact of the staff when the heat setting plate 3 is not needed.

[0047] In the above structure, if the positions of the four groups of clamping components are adjusted manually, it will be time-consuming, labor-intensive, and the adjustment will be imprecise. Therefore, the workbench 1 is also provided with a spacing adjustment component for adjusting the four groups of clamping components.

[0048] In this embodiment, the spacing adjustment assembly includes a mounting plate 14, a support plate 15, a rack 16, a gear 17, a positive and negative threaded screw 18, a first hinge seat 19, a second hinge seat 20, a hinge rod 21, an adjustment plate 22, a first guide rod 23 and a guide frame 24. The mounting plates 14 are symmetrically arranged on the left and right sides of the lifting plate 13, a rack 16 is arranged below the mounting plate 14, a support plate 15 is arranged between the four groups of legs 2, a slide groove is arranged at the center above the support plate 15, and a positive and negative threaded screw 18 is rotatably arranged in the slide groove, the left and right ends of the positive and negative threaded screw 18 pass through the support plate 15 and are connected to the center of the gear 17, the corresponding rack 16 is meshed with the gear 17, the first hinge seat 19 is arranged in two groups of symmetrical arrangements, the first hinge seat 19 extends into the slide groove below and is connected to the positive and negative threaded screw 18, Two groups of symmetrically arranged second hinge seats 20 are also provided below the adjustment plate 22, and the upper and lower ends of the hinge rod 21 are respectively hinged to the corresponding second hinge seats 20 and the first hinge seats 19, and a first guide rod 23 is provided below the slider 5. The four corners of the adjustment plate 22 are provided with guide frames 24 with upper opening inclined grooves, and the first guide rod 23 is inserted into the guide frame 24. The guide frame 24 is provided with a release hole adapted to the first guide rod 23 at one end away from the center of the workbench 1. When the lifting plate 13 is initially at a higher position, the distance between the two groups of first hinge seats 19 is larger. At this time, the adjustment plate 22 drives the guide frame 24 to be at a lower position, and the clamping assembly can slide freely on the sliding hole (that is, when the distance between the lifting plate 13 and the workbench 1 is larger, the material is placed on the workbench 1, and the four corners of the carpet are fixed by the clamping assembly);

[0049] The racks 16 below the mounting plates 14 on the left and right sides of the lifting plate 13 mesh with the gears 17. As the lifting plate 13 descends, the racks 16 drive the gears 17 to rotate, and the positive and negative threaded screws 18 rotate accordingly. The first hinge seat 19 extends below into the slide slot and is connected to the positive and negative threaded screws 18. The second hinge seat 20 below the adjustment plate 22 is hinged to the first hinge seat 19 through the hinge rod 21. When the positive and negative threaded screws 18 rotate, the first hinge seat 19 will move toward each other in the slide slot, and the hinge rod 21 supports the adjustment plate 22 with the second hinge seat 20 to rise. At this time, the guide frame 24 with the inclined groove abuts against the four groups of first guide rods 23, so that the four groups of clamping assemblies move toward the principle workbench 1. A hemisphere 32 is provided below the first guide rod 23, and the hemisphere 32 contacts the guide frame 24 to reduce the wear of the guide frame 24;

[0050] When the first guide rod 23 passes through the release hole, the lifting plate 13 with the heat setting plate 3 is located above the clamping assembly. At this time, the notch of the lifting plate 13 is adapted to the clamping assembly, and the lifting plate 13 continues to descend without causing motion interference with the clamping assembly. Due to the existence of the release hole, the two groups of first articulated seats 19 continue to feed toward each other, and the adjustment plate 22 rises, but the positions of the four groups of clamping assemblies no longer change until the heat setting plate 3 contacts the material in the middle part above the workbench 1 to perform the heat setting operation.

[0051] In actual use, if the pressing plate 8 is directly used in conjunction with the slider 5 to position and clamp the four corners of the carpet, it is necessary to ensure the stability of the carpet end angle state during the clamping process. For this purpose, a pre-positioning component is also provided on the pressing plate 8, and the pre-positioning component includes an elastic member and a fixed plate 25. The upper and lower ends of the elastic member are respectively connected to the pressing plate 8 and the fixed plate 25. The slider 5 is in an inverted L shape, and the upper part of the slider 5 protrudes from the workbench 1. The upper and lower ends of the elastic member (composed of a first spring 28 and a telescopic rod 29, and the first spring 28 is sleeved on the telescopic rod 29) are respectively connected to the pressing plate 8 and the fixed plate 25. When the pressing plate 8 presses the edge of the carpet downward, the elastic member can be extended and retracted according to the thickness of the carpet and other conditions, and the contact position and state of the carpet edge and the upper part of the slider 5 can be adjusted in time to adjust the end angle state of the carpet. The fixed plate 25 is also provided with a second guide rod 30 that passes through the pressing plate 8 to ensure the stability of the lifting and lowering of the pressing plate 8. The upper part of the slider 5 is close to the end of the workbench 1 and is provided with a lower positioning groove 26. The lower part of the fixed plate 25 is provided with an upper positioning groove 27 that matches the edge of the lower positioning groove 26. It should be noted that the lower positioning groove 26 is matched with the arc transition of the carpet end angle, and the upper positioning groove 27 is matched with the edge of the arc transition of the carpet. At this time, the staff can observe the arc transition of the carpet end angle and the two edge positions of the carpet, and observe from three angles to ensure the stability of the flat state of the carpet edge end angle and ensure that the carpet edge will not shift during the edge pulling process.

[0052] During actual use, in order to facilitate the stable fixation of the four corners of the carpet, the carpet is initially placed on the workbench 1 in an incompletely unfolded state, and four sets of clamping assemblies are required to be close to the middle part of the workbench 1. For this purpose, the support rod 4 is also provided with a second spring 31, and the two ends of the second spring 31 are respectively connected to the inner wall of the sliding hole away from the center of the workbench 1 and the slider 5. When the clamping assemblies are not supported by the spacing adjustment assemblies, the four sets of clamping assemblies are arranged close to the center of the workbench 1.

[0053] In actual use, if the gear 17 and the rack 16 are directly exposed to the outside, they are easily affected by dust and debris. The left and right sides of the workbench 1 are also provided with protective components for protecting the rack 16 and the gear 17. The protective components include a cover body 33 and a cover 34. The cover bodies 33 are symmetrically arranged on the left and right sides of the workbench 1. An active cavity is arranged in the cover body 33. The rack 16 passes through the top wall of the cover body 33 and meshes with the rack 16 in the active cavity. The forward and reverse thread screws 18 pass through the cover body 33. The cover body 33 is connected to the support plate 15. An inspection port is arranged on the side of the cover body 33 away from the workbench 1. The cover cover 34 is adapted to the inspection port. Guide rollers 35 for guiding the rack 16 are symmetrically arranged at the front and rear ends of the movable cavity, and the outer wall of the guide rollers 35 is provided with guide grooves adapted to the rack 16. The guide rollers 35 symmetrically arranged at the front and rear ends of the movable cavity, and the guide grooves of the outer wall thereof are adapted to the rack 16, providing guidance for the movement of the rack 16, ensuring the stability of the movement of the rack 16. The cover body 33 is away from the inspection port on one side of the workbench 1 and the adapted cover 34, which is convenient for the inspection and maintenance of the internal rack 16 and the gear 17. At the same time, the cover body 33 and the cover 34 can protect the rack 16 and the gear 17 from the influence of external dust, debris, etc., ensure the stability of the meshing of the gear 17 and the rack 16, and extend the service life of the equipment;

[0054] In this embodiment, a cleaning hole communicating with the slide groove is further provided on the support plate 15 to ensure the stability of movement of the two sets of first hinge seats 19 .
