Description

Technical Field

[0001] The present application relates to the technical field of sewing machine use, and in particular to a novel hemming sewing machine. Background Art

[0002] In daily life, the edges and corners of fabrics are easily worn, so merchants will wrap the edges and corners of fabrics with edging to enhance the durability of the fabrics, that is, sew the edging on the edges and corners of the fabrics with a sewing machine.

[0003] The sewing machine uses a stitching thread to sew two stacked materials along the movement trajectory of the needle relative to the materials by moving the needle vertically up and down. When sewing the hems, merchants need to ensure that the hems on both sides are parallel to the edge of the fabric for the beauty of the clothes. When actually operating the sewing machine, the staff can only sew by visual inspection, which results in a low pass rate of fabric hems. Summary of the invention

[0004] The embodiment of the present application provides a new type of hemming sewing machine to solve the problem of low hemming qualification rate of sewing machines used in the related art.

[0005] In a first aspect, a novel hemming sewing machine is provided, comprising:

[0006] A workbench, on which there is a moving area for the cloth or the hemming to slide in the same direction, and on which there are needles;

[0007] A plurality of limiting structures are stacked alternately on the workbench, and the limiting structures include:

[0008] - Place the board;

[0009] - A limiting plate, which is connected to the placement plate, is vertically arranged on the placement plate, is parallel to the moving direction of the fabric or the hemming, and a limiting area for limiting the sliding of the fabric or the hemming is provided between the placement plate and the limiting plate;

[0010] When the fabric or the binding edge passes through the limiting area, the fabric or the binding edge is closely attached to the placement plate and the limiting plate.

[0011] In some embodiments, the placement plate includes a fixed plate and a telescopic plate;

[0012] The telescopic plate is slidably connected in the fixed plate, and the telescopic plate is connected to the limiting plate.

[0013] In some embodiments, the limiting structure further includes a screw rod and a control rod;

[0014] The control rod is rotatably connected to the fixed plate, and the control rod is used to drive the screw rod to rotate. One end of the screw rod is rotatably connected to the fixed plate, and the screw rod is threadably matched with the telescopic plate.

[0015] In some embodiments, the placement plate is connected to a limiting plate of another limiting structure.

[0016] Some embodiments further include a tightening plate and a cross plate;

[0017] The horizontal plate is connected with the limiting plate of the uppermost limiting structure, and the tightening plate is slidably connected with the horizontal plate.

[0018] In some embodiments, the tightening plate gradually approaches the workbench along the moving direction of the fabric or the hemming.

[0019] In some embodiments, one end of the tightening plate close to the workbench extends parallel to the workbench and forms a flat plate.

[0020] The embodiment of the present application provides a novel hemming sewing machine. Since the present application limits the height of the fabric and the hemming on the workbench by placing a plate, the hemming is U-shaped and the edge of the fabric is located inside the hemming. The position of the fabric and the hemming is limited by a limiting plate so that the edge of the fabric is parallel to the edge of the hemming. In summary, the fabric and the hemming are made parallel to the edge of the hemming during sewing by multiple limiting structures. Therefore, the present application limits the position of the fabric or the hemming by multiple superimposed limiting structures, assists the staff in using needle and thread for sewing, and improves the pass rate.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides a new type of hemming sewing machine, which can solve the problem of low hemming qualification rate of sewing machines used in related technologies.

[0030] See also Figures 1 to 3 , a new type of hemming sewing machine, comprising:

[0031] A workbench 1, on which there is a moving area for the cloth or the hemming to slide in the same direction, and on which there are needles 2;

[0032] A plurality of limiting structures 3 are stacked alternately on the workbench 1, and the limiting structures 3 include:

[0033] - Placement plate 31;

[0034] - a limiting plate 32, the limiting plate 32 is connected to the placing plate 31, the limiting plate 32 is vertically arranged on the placing plate 31, the limiting plate 32 is arranged parallel to the moving direction of the cloth or the hemming, and a limiting area for limiting the sliding of the cloth or the hemming is provided between the placing plate 31 and the limiting plate 32;

[0035] When the fabric or the hemming passes through the limiting area, the fabric or the hemming is in close contact with the placement plate 31 and the limiting plate 32;

[0036] The placement plate 31 is connected to the limiting plate 32 of another limiting structure 3;

[0037] Limiting structure such as Figure 5As shown, there are three limiting structures in the present application, and the three limiting structures 3 are stacked into a "bow" shape. The lowest placement plate 31 is connected to the workbench 1. When the present application is used, the hemming slides in one direction on the workbench 1 and passes through the three stacked limiting structures 3. At this time, the hemming is generally U-shaped, and the edges of the hemming are respectively pressed against the top and bottom limiting plates 32, and a part of the hemming is attached to the top and bottom placement plates 31. The cloth, like the hemming, slides in one direction on the workbench 1 and passes through the three stacked limiting structures 3. The edge of the cloth that needs to be hemmed is attached to the middle limiting plate 32, and the cloth is attached to the middle placement plate 31. After the hemming and the cloth pass through the three limiting structures as described above, the hemming edge and the cloth edge are parallel to each other, and are parallel to all the limiting plates 32. In this case, the hemming edge and the cloth are sewn together with needle and thread, and the hemming edge and the cloth edge are parallel, thereby ensuring the qualified rate of the product.

[0038] The placement plate 31 includes a fixed plate 311 and a telescopic plate 312;

[0039] The telescopic plate 312 is slidably connected in the fixed plate 311, and the telescopic plate 312 is connected to the limiting plate 32;

[0040] The limiting structure 3 also includes a screw rod 33 and a control rod 34;

[0041] The control rod 34 is rotatably connected to the fixed plate 311, and the control rod 34 is used to drive the screw rod 33 to rotate. One end of the screw rod 33 is rotatably connected to the fixed plate 311, and the screw rod 33 is threadedly matched with the telescopic plate 312;

[0042] In a preferred embodiment, the placement plate 31 is two retractable plates, namely a fixed plate 311 and a retractable plate 312. One end of the control rod 34 is located inside the fixed plate 311, and the control rod 32 extends outside the fixed plate 311. The control rod 32 located outside the fixed plate 311 is convenient for the staff to control the rotation of the control rod 32. A bevel gear is connected to one end of the control rod 34 located inside the fixed plate 311, and another bevel gear is connected to the screw 33. The two bevel gears are meshed to achieve the purpose of driving the screw 33 to rotate by rotating the control rod 34. When the screw rotates, the fixed plate 311 and the retractable plate 312 are moved closer or farther away. The screw 33 is self-locking, so the positions of the fixed plate 311 and the retractable plate 312 will not change arbitrarily after adjusting the placement plate 31.

[0043] When the three limit structures are installed together, such as Figure 2 As shown, the placement plate 31 of the bottom limiting structure 3 needs to be connected to the workbench 1, so it is a whole plate, and the other two placement plates 31 include a fixed plate 311 and a telescopic plate 312, and are driven by a screw 33 and a control rod 34. The positions of the middle and top two limiting plates 32 are adjusted according to the needs of edging and fixed at different positions of the edge of the fabric.

[0044] It also includes a tightening plate 4 and a horizontal plate 5;

[0045] The horizontal plate 5 is connected to the limiting plate 32 of the uppermost limiting structure 3, and the tightening plate 4 is slidably connected to the horizontal plate 5;

[0046] The tightening plate 4 gradually approaches the workbench 1 along the moving direction of the fabric or the hemming;

[0047] After the fabric and the hemming pass through the stacked limiting structure 3, the fabric and the hemming are close to the tightening plate 4. As the tightening plate 4 gradually approaches the workbench 1, the hemming will gradually get close to the fabric. The closer the hemming is to the fabric, the smaller the deviation between the actual sewing position of the hemming and the fabric will be when the hemming and the fabric are sewn together.

[0048] It should be noted that the different positions of the fabric and the hemming are attached to the tightening plate 4, and the final sewing effect is also different. The best effect is that the hemming edge is attached to the tightening plate 4;

[0049] In order to facilitate the installation of the tightening plate 4, a transverse plate 5 is installed on the top limiting plate 32, and a slide rail and a slider are provided between the transverse plate 5 and the tightening plate 4. The slide rail is arranged on the transverse plate 5, and the slider is arranged on the collecting plate 4. The slider is slidably connected to the slide rail, so as to realize the function of the tightening plate 4 sliding on the transverse plate 5, and avoid the transverse plate 5 being driven to move due to the adjustment of the position of the top limiting structure 3, so that the position of the tightening plate 4 moves accordingly, resulting in the reduction of the effect of the tightening plate 4 on reducing the deviation of the hemming and fabric sewing.

[0050] One end of the tightening plate 4 close to the workbench 1 extends parallel to the workbench 1 and forms a flat plate;

[0051] A perforation for the needle to pass through is provided on the platform of the tightening plate 4. Figure 1 As shown, the perforations are linear and the length direction of the perforations is parallel to the moving direction of the tightening plate 4, ensuring that after the tightening plate 4 moves, the needle can still pass through the perforations to sew the hem to the fabric.

[0052] Here’s how this application works:

[0053] Before use, the present application first adjusts the positions of the three limiting structures 3 at the position where the edge of the fabric is sewn according to the needs of the edging, that is, adjusts the positions of the telescopic plate 312 and the limiting plate 32 through the control rod 34, and after the adjustment is completed, adjusts the position of the tightening plate 4 according to the positions of the lowermost and uppermost limiting plates 32, so that the edge of the edging is close to the tightening plate 4 after passing through the limiting structure 3. After the above adjustment is completed, the two side edges of the edging are respectively close to the uppermost and lowermost limiting plates 32 through the stacked limiting structures 3, and at the same time, the edge of the fabric is close to the middle limiting plate 32 through the stacked limiting structures 3, and finally the needle and thread are passed through the fabric and the edging to achieve the sewing of the fabric and the edging.
