DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] An embroidery flattening structure comprises an embroidery frame 1, a supporting frame 2 is fixedly connected to the bottom of the embroidery frame 1, clamping frames 3 are installed on the left and right sides of the embroidery frame 1, two groups of clamping frames 3 are installed with support plates 4 at one end away from the embroidery frame 1, the inner sides of the two groups of support plates 4 are rotatably connected with tightening rollers 5, the outer sides of the two groups of tightening rollers 5 are fixedly connected with fixing frames 6, and a fixing mechanism 7 is installed at the front end of the tightening roller 5 and on the front side of the support plate 4.

[0024] First, the front and rear ends of the two groups of clamping frames 3 are fixedly connected with locking ends 301, and the two groups of locking ends 301 on the same side are threadedly connected. The ends of the two groups of clamping frames 3 away from the embroidery frame 1 are rotatably connected to the support plate 4 through the connecting plate 303. When the embroidery fabric is flattened, the clamping frame 3 is first swung open through the connecting plate 303, and then the embroidery fabric is spread on the embroidery frame 1 for flattening. After the embroidery fabric is flattened, the clamping frame 3 is swung again to close the clamping frame 3 on the outside of the embroidery frame 1. At this time, the left and right ends of the embroidery fabric are tightened and flattened, while the front and rear ends are still loose. After the clamping frame 3 is closed, the front and rear ends of the embroidery fabric can be driven to tighten downward, thereby making the embroidery fabric flat and tightened as a whole. Finally, the locking end 301 is fixed by the locking bolt 302, so that the clamping frame 3 is used to clamp the embroidery fabric around to ensure the embroidery effect.

[0025] It should be noted here that when making the embroidery fabric of this scheme, traditional cloisonné thangka techniques and traditional embroidery techniques are combined. The patterns are made using the traditional cloisonné thangka memory and the traditional embroidery techniques are used to embroider the patterns. The two patterns are combined together to produce unique works of art and handicrafts.

[0026] Furthermore, the two groups of support plates 4 are fixedly connected to the side away from each other with an operating handle 401, the bottom ends of the two groups of support plates 4 are fixedly connected to a support seat 402, and the opposite ends of the two groups of support seats 402 are rotatably connected to two groups of moving wheels 403. When the embroidery fabric is flattened, the embroidery fabric is spread on the embroidery frame 1, and then the support plate 4 is tilted by controlling the operating handle 401 so that the moving wheel 403 contacts the ground, pushing the support plate 4 to move to the left and right sides of the embroidery frame 1, and then the support seat 402 is flattened to support the support plate 4.

[0027] Then, a clamping plate 601 is installed between the inner side of the fixed frame 6 and the tightening roller 5, and sliding grooves 602 are provided on the front and rear sides of the fixed frame 6. The front and rear ends of the clamping plate 601 are slidably connected to the sliding grooves 602 through sliding posts 603. The clamping plate 601 is fixedly connected with multiple groups of first springs 604 between the fixed frame 6. After the support plate 4 is placed stably, the left and right ends of the embroidery fabric are extended between the tightening roller 5 and the fixed frame 6, and the outer side of the sliding post 603 is threadedly connected with a fixing stud 605. The outer side of the fixing stud 605 and the front side of the support plate 4 are fixedly connected with a fixing ring 606. Loosen the fixing stud 605 so that the fixing ring 606 contacts the fixing of the sliding post 603. Under the action of the first spring 604, the clamping plate 601 is pressed down to compress and fix the embroidery fabric, and then tighten the fixing stud 605 to fix the left and right ends of the embroidery fabric. Then, the tightening roller 5 is rotated to tighten and flatten the embroidery fabric.

[0028] Secondly, the fixing mechanism 7 includes a crank handle 701 fixedly connected to the front end of the tightening roller 5, a fixed gear 702 is fixedly connected to the outer side of the crank handle 701, a connecting block 703 is fixedly connected to the front of the support frame 2 and located below the crank handle 701, a pull rod 704 is slidably connected inside the connecting block 703, a fixed tooth block 705 is fixedly connected to the top of the pull rod 704 and located on the outer side of the fixed gear 702, and a second spring 706 is sleeved on the outer side of the pull rod 704 and located between the fixed tooth block 705 and the connecting block 703. When the tightening roller 5 is rotated, the pull rod 704 is first pulled to make the fixed tooth block 705 move downward to release the fixation of the fixed gear 702, and then the crank 701 is rotated to drive the tightening roller 5 to rotate and tighten and flatten the embroidery fabric. After the embroidery fabric is flattened, the pull rod 704 is released to make the fixed tooth block 705 fix the fixed gear 702, thereby preventing the embroidery fabric from loosening after being flattened.

[0029] Finally, the fixed tooth block 705 is meshed with the fixed gear 702, and the bottom end of the pull rod 704 is fixedly connected with a pull handle 707. The left end of the bottom of the connecting block 703 is slidably connected to the connecting block 703 through a sliding rod 708. The pull rod 704 is operated by pulling the pull handle 707, and when the fixed tooth block 705 is pulled, the sliding rod 708 can improve the stability of the fixed tooth block 705 during movement.

[0030] In this embodiment, the implementation scenario is specifically as follows: when flattening the embroidery fabric, first swing the clamping frame 3 open through the connecting plate 303, and then spread the embroidery fabric on the embroidery frame 1 for flattening. After the embroidery fabric is spread on the embroidery frame 1, the support plate 4 is tilted by the operating handle 401 so that the moving wheel 403 contacts the ground, and the support plate 4 is pushed to move to the left and right sides of the embroidery frame 1. Then, the support seat 402 is flattened to support the support plate 4, and then the left and right ends of the embroidery fabric are extended between the tightening roller 5 and the fixed frame 6, and the fixing stud 605 is loosened so that the fixing ring 606 contacts the fixing of the sliding column 603. Under the action of the first spring 604, the pressing plate 601 is pressed down to press and fix the embroidery fabric, and then the fixing stud 605 is tightened to fix the left and right ends of the embroidery fabric, and then the crank 701 is turned to drive the tightening roller 5 to rotate to tighten the embroidery fabric. After the embroidery fabric is flattened, the pull rod 704 is loosened so that the fixed tooth block 705 fixes the fixed gear 702, thereby preventing the embroidery fabric from loosening after being flattened. After the embroidery fabric is flattened, the clamping frame 3 is swung to close the clamping frame 3 on the outside of the embroidery frame 1. At this time, the left and right ends of the embroidery fabric are tightened and flattened, while the front and back ends are still loose. After the clamping frame 3 is closed, the front and back ends of the embroidery fabric can be driven to be tightened downward, thereby making the embroidery fabric flat and tightened as a whole. Finally, the locking end 301 is fixed by the locking bolt 302, so that the clamping frame 3 is used to clamp the embroidery fabric around to ensure the embroidery effect. The whole operation process is simple and convenient. Compared with the existing structure for fixing and clamping embroidery fabric, the utility model can flatten the embroidery fabric before the fixed top clamps the embroidery fabric through design, and clamp the embroidery fabric around to ensure the embroidery effect after the embroidery fabric is flattened.
