Description

Technical Field

[0001] This utility model relates to the field of cotton shoe processing technology, and in particular to a processing device with the function of adjusting the spacing of cotton shoe seams. Background Technology

[0002] As an important category of winter warmth, the stitching process of cotton shoes has a key impact on the comfort and durability of the product. During the stitching process, a sewing machine is usually used, which can greatly improve work efficiency compared to manual sewing.

[0003] In the existing technology, traditional cotton shoe sewing machines have significant drawbacks. For example, when different types of cotton shoes require different stitch spacing, adjusting the stitch spacing of traditional sewing machines often requires disassembling the machine and using a screwdriver. This method is not only very troublesome but also seriously affects work efficiency. Therefore, this utility model proposes a processing device with the function of adjusting the stitch spacing of cotton shoes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a processing device with the function of adjusting the spacing of the stitches in cotton shoes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A processing device with the function of adjusting the spacing of stitches in cotton shoes includes a machine head. An opening is provided on the side wall of the machine head. A rotating shaft is rotatably connected to the inner wall of the machine head. A second motor is fixedly connected to the end of the rotating shaft. A turntable is concentrically fixedly sleeved on the second motor. A limiting plate is fixedly connected to the side wall of the machine head. A limiting groove is provided on the limiting plate. A limiting block is slidably connected within the limiting groove. A needle is fixedly connected to the end of the limiting block. A fixing plate is eccentrically fixedly connected to one end of the turntable near the opening. A sliding groove is provided on the fixing plate. An adjusting mechanism for adjusting the stroke of the needle is provided within the sliding groove. The adjusting mechanism includes a slider slidably connected within the sliding groove. A U-shaped block is fixedly connected to the end of the limiting block. A swing rod is rotatably connected between the U-shaped block and the slider.

[0007] Preferably, a threaded rod is rotatably connected to the inner wall of the fixing plate, the end of the threaded rod passes through the side wall of the fixing plate and is rotatably connected thereto, and the threaded rod passes through the slider and is threadedly connected thereto.

[0008] Preferably, a first bevel gear is fixedly sleeved at the end of the threaded rod, and a second bevel gear that meshes with the first bevel gear is fixedly connected to the end of the output shaft of the second motor.

[0009] Preferably, a toothed ring is fixedly connected to the side wall of the turntable.

[0010] Preferably, a first motor is fixedly connected to the inner wall of the machine head, and a gear that meshes with the gear ring is fixedly connected to the end of the output shaft of the first motor.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] By setting an adjustment mechanism, when the needle pitch needs to be adjusted, the output shaft of the second motor can be driven to rotate, which in turn drives the second bevel gear to rotate. The rotation of the second bevel gear can drive the first bevel gear meshing with it to rotate, which in turn drives the threaded rod to rotate, thereby moving the slider connected to it by the thread. The movement of the slider can move one end of the swing rod, adjusting the distance between the end of the swing rod and the center of the turntable, thereby adjusting the rotation radius of the slider. This eliminates the need for disassembling the machine for manual adjustment, greatly improving work efficiency. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1-8 A processing device with the function of adjusting the spacing of the stitches in cotton shoes includes a machine head 1, an opening 2 on the side wall of the machine head 1, a rotating shaft 18 rotatably connected to the inner wall of the machine head 1, a second motor 16 fixedly connected to the end of the rotating shaft 18, a turntable 3 concentrically fixedly sleeved on the second motor 16, a limiting plate 4 fixedly connected to the side wall of the machine head 1, a limiting groove 6 opened on the limiting plate 4, a limiting block 11 slidably connected in the limiting groove 6, and a needle 5 fixedly connected to the end of the limiting block 11.

[0024] Specifically, a fixed plate 12 is eccentrically fixed to one end of the turntable 3 near the opening 2. A groove 19 is provided on the fixed plate 12. An adjustment mechanism for adjusting the stroke of the needle 5 is provided in the groove 19. The adjustment mechanism includes a slider 20 slidably connected in the groove 19. A U-shaped block 13 is fixedly connected to the end of the limiting block 11. A swing rod 8 is rotatably connected between the U-shaped block 13 and the slider 20.

[0025] Specifically, a threaded rod 7 is rotatably connected to the inner wall of the fixed plate 12. The end of the threaded rod 7 passes through the side wall of the fixed plate 12 and is rotatably connected to it. The threaded rod 7 passes through the slider 20 and is threadedly connected to it. A first bevel gear 9 is fixedly sleeved at the end of the threaded rod 7. A second bevel gear 10 that meshes with the first bevel gear 9 is fixedly connected to the end of the output shaft of the second motor 16.

[0026] Specifically, a gear ring 14 is fixedly connected to the side wall of the turntable 3, and a first motor 15 is fixedly connected to the inner wall of the machine head 1. A gear 17 that meshes with the gear ring 14 is fixedly connected to the end of the output shaft of the first motor 15. The gear ring 14 is coaxial with the turntable 3.

[0027] In use, this invention drives the output shaft of the first motor 15 to rotate, which in turn drives the gear 17 to rotate. The rotation of the gear 17 drives the gear ring 14 to rotate, which in turn drives the turntable 3 to rotate. This causes the fixed plate 12 to rotate around the rotating shaft 18, which in turn drives the slider 20 to rotate around the rotating shaft 18. This causes the swing rod 8 to swing, which in turn causes the limiting block 11 to reciprocate within the limiting groove 6, and causes the needle 5 to reciprocate, thus completing the needle insertion. When it is necessary to adjust the needle spacing, the output shaft of the second motor 16 can be driven to rotate, which in turn drives the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 can drive ... second bevel gear 10 to rotate, which in turn drives the second bevel gear 10 to rotate. The first bevel gear 9, which meshes with the spool, rotates, causing the threaded rod 7 to rotate, which in turn causes the slider 20, which is threadedly connected to it, to move. The movement of the slider 20 can move one end of the swing rod 8. By adjusting the distance between the end of the swing rod 8 and the center of the turntable 3, the rotation radius of the slider 20 can be adjusted, thereby adjusting the swing amplitude of the swing rod 8, adjusting the moving distance of the limit block 11, and thus adjusting the movement amplitude of the needle 5. When the movement amplitude is large, the speed is low and the needle distance is large; when the movement amplitude is small, the speed is high and the needle distance is small. No manual adjustment is required without disassembling the machine, which can greatly improve work efficiency.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
