Description

Technical Field

[0001] This utility model relates to the field of buttonhole machine technology, and in particular to buttonhole machines for garment processing. Background Technology

[0002] A buttonhole machine for garment processing is a specialized piece of equipment used in the garment manufacturing industry, specifically designed to create buttonholes on various garment fabrics. Its core function is to sew reinforced buttonholes on areas such as plackets and waistbands, ensuring that buttons are not easily detached after installation, thus enhancing the practicality and aesthetics of the garment. This device typically consists of a machine frame, sewing machine head, needle bar drive mechanism, fabric feeding device, and control system.

[0003] Currently available buttonhole machines for garment processing generally lack effective protective measures, posing significant safety hazards when the needle breaks. Traditional buttonhole machine needles may break when piercing fabrics at high speeds (especially stiff fabrics such as denim and thick canvas) due to uneven fabric tension, needle wear, or improper sewing parameter settings. Lacking protective structures, the broken needle can fly off at high speed due to inertia, posing a direct threat to the operator. The flying needle may puncture the skin or splash into the eyes, causing an accident. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a buttonhole machine for garment processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a buttonhole machine for garment processing, comprising a buttonhole machine body, a sliding groove on one side of the buttonhole machine body, a lead screw rotatably connected to the inside of the sliding groove via a bearing, a lifting plate threadedly connected to the outer surface of the lead screw, the lifting plate slidably connected to the buttonhole machine body via the sliding groove, a U-shaped frame fixedly connected to the front of the lifting plate, a connecting rod fixedly connected to the inner wall of the U-shaped frame, a rotating frame rotatably connected to the outer surface of the connecting rod, a transparent plate fixedly connected to the inner wall of the rotating frame, an arc-shaped gear sleeve fixedly connected to the end of the rotating frame away from the transparent plate, an L-shaped bracket fixedly connected to the top surface of the U-shaped frame, two symmetrically arranged springs fixedly connected to the inner wall of the L-shaped bracket, toothed plates fixedly connected to the bottom ends of the two springs, the toothed plates meshing with the arc-shaped gear sleeve, two symmetrically arranged limiting posts fixedly connected to the top surface of the toothed plates, both limiting posts slidably connected to the L-shaped bracket, and a pull plate parallel to the L-shaped bracket fixedly connected to the top of the two limiting posts.

[0007] Preferably, one side of the lifting plate has a threaded hole, and the lifting plate is threadedly connected to the lead screw through the threaded hole.

[0008] Preferably, in any of the above solutions, the slide groove has two symmetrically arranged guide rods fixedly connected inside, and the lifting plate is slidably connected to the guide rods.

[0009] Preferably, in any of the above solutions, the front of the lifting plate is fixedly connected to two symmetrically arranged reinforcing ribs, and the tops of the two reinforcing ribs are fixedly connected to the U-shaped frame.

[0010] Preferably, one side of the rotating frame has a through-hole, and the rotating frame is rotatably connected to the connecting rod through the through-hole.

[0011] Preferably, in any of the above embodiments, a control knob is rotatably connected to the top of the buttonhole machine body via a bearing, and the top of the control knob is fixedly connected to the top of the lead screw.

[0012] Preferably, in any of the above solutions, the top surface of the L-shaped bracket has two symmetrically arranged limiting holes, and both limiting posts are slidably connected to the L-shaped bracket through the limiting holes.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the safety hazard of traditional buttonhole machines where broken needles can easily fly off and injure operators, this garment buttonhole machine employs a clever structural design to provide reliable protection. A rotating frame on a U-shaped stand connects to a transparent plate. When the pull plate moves the toothed plate upwards against the spring's force, the toothed plate disengages from the arc-shaped gear sleeve, allowing the rotating frame to rotate around the connecting rod, positioning the transparent plate in front of the needle's working area to form a protective barrier. Releasing the pull plate causes the spring to push the toothed plate back to its original position, engaging with the arc-shaped gear sleeve to fix the rotating frame and transparent plate in place. In this way, even if the needle breaks while piercing thick fabrics, the transparent plate effectively prevents the broken needle from flying off at high speed, avoiding injury to the operator and significantly improving the safety of the buttonhole machine during use.

[0015] 2. The lead screw and lifting plate on the main body of the buttonhole machine are connected by a threaded hole. The operator rotates the control knob, causing the lead screw to rotate within the slide groove, which in turn drives the lifting plate to slide up and down along the guide rod. This allows for flexible height adjustment of components such as the U-shaped frame, rotating frame, and transparent plate to accommodate buttonhole processing needs of fabrics of different thicknesses. Simultaneously, the reinforcing ribs on the front of the lifting plate are fixedly connected to the U-shaped frame, enhancing the stability of the lifting structure and ensuring that components do not wobble or shift during adjustment. The locking structure, composed of the L-shaped bracket, spring, and toothed plate, precisely fixes the rotation angle of the rotating frame, ensuring the transparent plate remains stable in the protective position. This allows the operator to perform buttonhole operations conveniently and accurately while maintaining safety, improving the practicality and ease of operation of the buttonhole machine.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 5As shown, a buttonhole machine for garment processing includes a buttonhole machine body 1. A slide groove 2 is provided on one side of the buttonhole machine body 1. A lead screw 3 is rotatably connected to the inside of the slide groove 2 via bearings. A lifting plate 4 is threadedly connected to the outer surface of the lead screw 3. The lifting plate 4 is slidably connected to the buttonhole machine body 1 via the slide groove 2. A U-shaped frame 5 is fixedly connected to the front of the lifting plate 4. A connecting rod 6 is fixedly connected to the inner wall of the U-shaped frame 5. A rotating frame 7 is rotatably connected to the outer surface of the connecting rod 6. A transparent plate 8 is fixedly connected to the inner wall of the rotating frame 7. The rotating frame 7 is located away from the transparent plate. One end of the U-shaped frame 8 is fixedly connected to an arc-shaped gear sleeve 9. The top surface of the U-shaped frame 5 is fixedly connected to an L-shaped bracket 10. The inner wall of the L-shaped bracket 10 is fixedly connected to two symmetrically arranged springs 11. The bottom ends of the two springs 11 are fixedly connected to a toothed plate 12. The toothed plate 12 meshes with the arc-shaped gear sleeve 9. The top surface of the toothed plate 12 is fixedly connected to two symmetrically arranged limiting posts 13. Both limiting posts 13 are slidably connected to the L-shaped bracket 10. The top ends of the two limiting posts 13 are fixedly connected to a pull plate 14 parallel to the L-shaped bracket 10.

[0024] As an optional technical solution of this utility model, a threaded hole 15 is provided through one side of the lifting plate 4. The lifting plate 4 is threadedly connected to the lead screw 3 through the threaded hole 15. The operator only needs to rotate the lead screw 3 to drive the lifting plate 4 to move smoothly in the vertical direction through the threaded transmission, thereby adjusting the position of components such as the U-shaped frame 5, the rotating frame 7 and the transparent plate 8 to adapt to the buttonhole processing of fabrics of different thicknesses.

[0025] As an optional technical solution of this utility model, the slide groove 2 is fixedly connected with two symmetrically arranged guide rods 16. The lifting plate 4 is slidably connected to the guide rods 16. The guide rods 16 provide a clear guiding path for the movement of the lifting plate 4, effectively limiting the possible offset or shaking of the lifting plate 4 during the movement, and avoiding component damage or processing errors caused by the tilting of the lifting plate 4.

[0026] As an optional technical solution of this utility model, the front of the lifting plate 4 is fixedly connected with two symmetrically arranged reinforcing ribs 17. The top of the two reinforcing ribs 17 is fixedly connected to the U-shaped frame 5. The reinforcing ribs 17 can effectively disperse and transmit the stress generated by the U-shaped frame 5 and its components during operation, reduce the deformation of the lifting plate 4 due to force, and prevent problems such as poor fit between the lead screw 3 and the threaded hole 15 and jamming between the guide rod 16 and the lifting plate 4 caused by the deformation of the lifting plate 4.

[0027] As an optional technical solution of this utility model, a rotating hole 18 is provided through one side of the rotating frame 7. The rotating frame 7 is rotatably connected to the connecting rod 6 through the rotating hole 18. This design provides convenience for adjusting the position of the transparent plate 8. Operators can easily rotate the transparent plate 8 to a suitable angle according to actual processing needs, so that it can better play its protective role.

[0028] As an optional technical solution of this utility model, the top of the buttonhole machine body 1 is rotatably connected to a control knob 19 via a bearing. The top of the control knob 19 is fixedly connected to the top of the lead screw 3. By directly rotating the control knob 19, the lead screw 3 can be easily rotated, thereby realizing the lifting adjustment of the lifting plate 4 without the need for other complicated tools or cumbersome operating steps.

[0029] As an optional technical solution of this utility model, the top surface of the L-shaped bracket 10 has two symmetrically arranged limiting holes 20. Both limiting posts 13 are slidably connected to the L-shaped bracket 10 through the limiting holes 20. The limiting holes 20 ensure that the limiting posts 13 can only slide in the vertical direction, thereby restricting the movement trajectory of the toothed plate 12 and making it only move up and down in a fixed direction. This prevents the toothed plate 12 from deviating or tilting during movement and ensures that the toothed plate 12 and the arc-shaped gear sleeve 9 always maintain a good meshing state.

[0030] The working principle of a buttonhole machine for garment processing is as follows:

[0031] 1): The rotating frame 7 on the U-shaped frame 5 is connected to the transparent plate 8. When the pull plate 14 pulls the toothed plate 12 to overcome the elastic force of the spring 11 and move upward, the toothed plate 12 disengages from the arc-shaped gear sleeve 9, and the rotating frame 7 can rotate around the connecting rod 6 to rotate the transparent plate 8 to the front of the needle working area to form a protective barrier.

[0032] 2): After the pull plate 14 is released, the spring 11 pushes the toothed plate 12 to return to its original position, and engages with the arc-shaped gear sleeve 9 to fix the position of the rotating frame 7 and the transparent plate 8.

[0033] 3): When the operator turns the control knob 19, the lead screw 3 can rotate in the slide groove 2, thereby driving the lifting plate 4 to slide up and down along the guide rod 16, so as to flexibly adjust the height of components such as the U-shaped frame 5, the rotating frame 7 and the transparent plate 8.

[0034] In summary, this buttonhole machine for garment processing provides reliable protection through its ingenious structural design. The rotating frame 7 on the U-shaped frame 5 is connected to the transparent plate 8. When the pull plate 14 pulls the toothed plate 12 to overcome the elastic force of the spring 11 and move it upward, the toothed plate 12 disengages from the arc-shaped gear sleeve 9, and the rotating frame 7 can rotate around the connecting rod 6, rotating the transparent plate 8 to the front of the needle working area to form a protective barrier. After the pull plate 14 is released, the spring 11 pushes the toothed plate 12 to return to its original position, engaging with the arc-shaped gear sleeve 9 to fix the position of the rotating frame 7 and the transparent plate 8. In this way, even if the needle breaks while piercing thick fabrics, the transparent plate 8 can effectively prevent the broken needle from flying off at high speed, thus avoiding injury to the operator and significantly improving the safety of the buttonhole machine. The lead screw 3 on the main body 1 of the buttonhole machine is connected to the lifting plate 4 through the threaded hole 15. When the operator turns the control knob 19, the lead screw 3 can be rotated in the slide groove 2, thereby driving the lifting plate 4 to slide up and down along the guide rod 16, realizing flexible adjustment of the height of components such as the U-shaped frame 5, the rotating frame 7 and the transparent plate 8 to adapt to the buttonhole processing needs of fabrics of different thicknesses. Meanwhile, the reinforcing ribs 17 on the front of the lifting plate 4 are fixedly connected to the U-shaped frame 5, which enhances the stability of the lifting structure and ensures that the components will not shake or shift during the adjustment process. The locking structure composed of components such as the L-shaped bracket 10, spring 11, and toothed plate 12 can accurately fix the rotation angle of the rotating frame 7, ensuring that the transparent plate 8 remains stable in the protective position. This allows operators to perform keyhole operations conveniently and accurately under safe conditions, improving the practicality and ease of operation of the keyhole machine.
