[0002] Piping knitted fabrics usually refer to specially designed or treated knitted fabrics, whose edges are processed or sewn to prevent curling and loosening. This treatment is usually used to improve the durability and aesthetics of the fabric, especially in clothing manufacturing.

[0003] Most of the thin fabrics currently available on the market have relatively large elasticity, so rolling collars, rolling cuffs and rolling edges are difficult to operate. The uneven cloth feeding of the rolling strip will cause uneven vertical feeding of the clothes. Rolling collars will cause the collars to be tilted or turned inside out, or the collars will be higher on the left and lower on the right, resulting in a poor appearance. When sewing, the staff also needs to constantly smoothen them, which reduces the processing efficiency and brings a workload to the staff. Therefore, the utility model designs a rolling edge knitted fabric anti-curling template based on the technical problems raised. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a template for preventing curling of rolled knitted fabrics, comprising a hollow frame 1 and a transmission belt 7. The left and right ends of the inner bottom of the hollow frame 1 are fixedly connected with baffles 3. The front side of the left baffle 3 is rotatably connected with a first worm 4. The front end of the first worm 4 passes through the hollow frame 1. The front end of the right baffle 3 is rotatably connected with a second worm 5. The outer front ends of the first worm 4 and the second worm 5 are fixedly connected with pulleys 6. The two pulleys 6 are connected by a transmission belt 7. The left and right ends of the inner top of the hollow frame 1 are fixedly connected with fixed rods 8. The bottom end of the fixed rod 8 is fixedly connected with a ring 9. The inside of the ring 9 is rotatably connected with a movable rod 10. The adjacent ends of the two movable rods 10 are fixedly connected with worm wheels 12. The two worm wheels 12 are respectively meshed with the corresponding first worm 4 and second worm 5. A plurality of T-slots 13 are provided on the inner top of the hollow frame 1. A T-block 14 is slidably connected inside the T-slot 13. The T-block 1 4 is fixedly connected with a rack 15 at the bottom, and the ends of the two movable rods 10 that are far away are fixedly connected with cylindrical gears 11. The two racks 15 are respectively meshed with the corresponding cylindrical gears 11. The rear side of the rack 15 is fixedly connected with a connecting rod 16, and the rear ends of the two connecting rods 16 are fixedly connected with the same movable plate 17. An open groove 18 is provided on the inner rear side of the hollow frame 1. A screw rod 19 is rotatably connected to the rear side of the top of the hollow frame 1. The bottom end of the screw rod 19 passes through the open groove 18 and is threadedly connected with a pressure plate 20. A clamping mechanism 2 is provided on the top of the hollow frame 1. The sizes of the two T-blocks 14 are respectively consistent with the internal sizes of the corresponding T-slots 13. The bottom end of the screw rod 19 is rotatably connected to the inner bottom of the open groove 18. The front end of the second worm 5 is rotatably connected to the right side of the inner front end of the hollow frame 1. The rear side of the pressure plate 20 is slidably connected to the inside of the open groove 18, and the size of the rear side of the pressure plate 20 matches the size of the inside of the open groove 18.

[0038] Specifically, the pulley 6 on the outer side of the first worm 4 rotates accordingly. This rotation is not performed in isolation, but through a carefully designed transmission belt 7, the power is transmitted to the pulley 6 on the outer side of the second worm 5, thereby driving the second worm 5 to rotate synchronously. As the second worm 5 rotates, the worm wheel 12 meshing with it also starts to rotate. The rotation of the worm wheel 12 further drives the rotation of the movable rod 10 connected to it. The other end of the movable rod 10 is connected to the cylindrical gear 11. When the cylindrical gear 11 rotates, the rack 15 will move backward inside the T-slot 13. As the rack 15 moves, the movable plate 17 connected to it will also move backward. The internal width of the template can be flexibly adjusted according to the different requirements of the hemming width. When the internal width of the template is adjusted, the screw rod 19 is rotated to drive the pressing plate 20 to move downward to limit the clamping of the fabric. This limit clamping process is not only rapid, but also has uniform clamping force, which can ensure that the fabric will not shift or wrinkle during the processing. This design eliminates the need for workers to constantly smooth the fabric during the sewing process, thereby greatly reducing the workload and improving work efficiency.

[0039] Reference Figure 1 The clamping mechanism 2 includes a rotating rod 201, and the two rotating rods 201 are rotatably connected to the left and right sides of the bottom of the hollow frame 1 respectively. The bottom end of the rotating rod 201 is fixedly connected to a U-shaped frame 202. A limiting rod 203 is provided at the bottom of the U-shaped frame 202. The upper and middle parts of the limiting rod 203 penetrate the U-shaped frame 202 and are fixedly connected to a clamping plate 204. A spring 205 is provided on the outer side of the limiting rod 203. The bottom ends of the two springs 205 are fixedly connected to the inner bottom of the corresponding U-shaped frame 202 respectively.

[0040] Specifically, pull the limit rod 203 downward, and the clamp 204 will open under the action of the limit rod 203 to form a gap for the edge of the workbench to be inserted, and then put one side of the workbench between the clamp 204 and the U-shaped frame 202 to ensure that the edge of the workbench fits tightly with the device, and then release the limit rod 203. At this time, the spring 205 will quickly release the previously squeezed force, pushing the clamp 204 to rebound quickly, and firmly clamping one side of the workbench, which can make the subsequent fabric processing work more stable, thereby improving the practicality of the template.

[0041] Reference Figure 1 and Figure 2 , the bottom of the pressing plate 20 and the rear side of the movable plate 17 are both fixedly connected with a rubber pad 21;

[0042] Specifically, the rubber pad 21 can further increase the friction between the pressing plate 20 and the movable plate 17 and the fabric.

[0043] Reference Figure 1 A groove 22 is provided in the middle of the top of the hollow frame 1;

[0044] Specifically, the groove 22 can facilitate the user to observe whether the fabric is in a flat state at any time.

[0045] Working principle: When using the template, first pass one end of the fabric to be processed through the hollow frame 1. At this time, observe the width of the fabric to be processed first, then rotate the first worm 4, and the pulley 6 on the outside will rotate accordingly. The pulley 6 on the outside of the second worm 5 will also rotate through the transmission belt 7, thereby driving the second worm 5 to rotate. At this time, the worm wheel 12 meshing with it will rotate accordingly, thereby driving the movable rod 10 to rotate. The cylindrical gear 11 at the other end of the movable rod 10 will also rotate accordingly, thereby driving the meshing rack 15 to move backward inside the T-slot 13, and the movable plate 17 will move backward accordingly. The internal width of the template can be adjusted according to the required hemming width. Then, the screw rod 19 can be rotated to drive the pressing plate 20 to move downward to limit and clamp the fabric. During sewing, the staff does not need to keep smoothing, thereby improving the processing efficiency of the fabric and reducing the workload of the staff.

[0046] When using the template, first carry it to the desired working position, then pull down the limit rod 203, then place one side of the workbench between the clamp 204 and the U-shaped frame 202, then release the limit rod 203, at this time the spring 205 will release the squeezed force and drive the clamp 204 to rebound to limit and clamp one side of the workbench, which can conveniently fix the template at the desired position, thereby improving the practicality of the template.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
