Abstract
Description
Technical Field
[0001] This utility model relates to a sewing machine, and more particularly to a laser sewing machine. Background Technology
[0002] In the current technology, sewing machines often use laser beams to determine the stitch to improve the accuracy of the sewing thread. However, the laser beam emitted by the current laser generator is blurry and distorted due to the short distance and the influence of the machine body. In addition, the feed tooth cover of current sewing machines is mostly a fixed structure and cannot be adjusted in height, which is not conducive to adjusting the distance between the feed tooth and the presser foot and the needle, thus reducing the scope of use. Summary of the Invention
[0003] To address the problems of existing technologies, this utility model provides a laser sewing machine that not only produces clear and accurate sewing stitches, but also allows for rapid adjustment of the feed tooth cover via a lifting mechanism, making it suitable for fabrics of different thicknesses.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A laser sewing machine includes a base, a machine body on top of the base, a machine head at the front of the machine body, a needle bar and a presser foot bar inside the machine head, a laser tube on one side of the needle bar inside the machine head, and a toothed refractive glass plate below the laser tube. The sewing thread laser beam emitted from the laser tube passes through the toothed refractive glass plate and is projected onto a feed tooth shield below the machine head. The feed tooth shield is raised and lowered by a lifting mechanism.
[0006] Preferably, the lifting mechanism includes a slider limiting bracket fixed in the base, a guide post is provided inside the slider limiting bracket, a lifting spring is provided outside the guide post, an upper slider and a lower slider that are interlocked are provided outside the guide post above the lifting spring, a spiral step that is interlocked is provided outside the upper slider and the lower slider, a lifting button is hinged to one side of the lower slider, and the top of the guide post abuts against the feed tooth cover.
[0007] Preferably, at least three spools are provided on the top of the machine body, and the sewing thread on the spools passes through the winding post provided on the top of the machine body and enters the interior of the machine body through the thread groove on the top of the machine body.
[0008] Preferably, the toothed refractive glass slide is screwed to the lower end of the laser tube via a shell with internal threads.
[0009] Preferably, the toothed refractive glass slide is mounted below the laser tube by a fixing frame.
[0010] The beneficial effects of the technical solution provided by this utility model are:
[0011] 1. A toothed refracting glass plate is installed at the top of the lamp tube to ensure that the projected trace of the beam is straight after it is excited.
[0012] 2. The lifting mechanism is based on the elastic positioning structure of a ballpoint pen, making it quick and easy to use. The lifting button has been moved to the side of the machine to ensure the stability of the feed tooth baffle after lifting.
[0013] 3. Multi-spool and open-wire winding guide for user convenience. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0020] Example 1
[0021] As attached Figure 1-4 As shown, a laser sewing machine according to this embodiment includes a base 1, a machine body 2 on top of the base 1, a machine head 3 in front of the machine body 2, a needle bar 4 and a presser foot bar 5 inside the machine head 3, a laser tube 6 on one side of the needle bar 4 inside the machine head 3, and a toothed refractive glass plate 7 below the laser tube 6. The sewing thread laser beam emitted from the laser tube 6 passes through the toothed refractive glass plate and is projected onto a feed tooth mask 8 below the machine head 3. The feed tooth mask 8 is raised and lowered by a lifting mechanism.
[0022] The lifting mechanism of this embodiment includes a slider limiting bracket 9 fixed in the base 1. A guide post 10 is provided inside the slider limiting bracket 9, and a lifting spring 11 is provided outside the guide post 10. An upper slider 12 and a lower slider 13, which are interlocked, are provided outside the guide post above the lifting spring 11. Spiral steps, which are interlocked, are provided outside the upper slider 12 and the lower slider 13. A lifting button 14 is hinged to one side of the lower slider 13. The top of the guide post 10 abuts against the feed tooth cover 8. When it is necessary to control the feed tooth cover 8 to rise, simply press the lifting button 14 to lower the lower slider 13, compressing the lifting spring 11. At this time, the upper slider 12 rotates and disengages from the interlocking state with the lower slider 13. Thus, by adjusting the height of the spiral steps, the maximum lifting height is achieved. Pressing the lifting button 14 again will change the interlocking position of the upper slider 12 and the lower slider 13 to the lowest interlocking state, thereby lowering the feed tooth cover 8. This principle is inspired by the press-and-release mechanism of a ballpoint pen.
[0023] In this embodiment, three spools 15 are provided on the top of the machine body 2. The sewing thread on the spools 15 passes through the winding post 16 provided on the top of the machine body 2 and enters the machine body through the thread groove 17 on the top of the machine body 2.
[0024] In this embodiment, the toothed refractive glass plate 7 is screwed to the lower end of the laser tube 6 through a shell with internal threads.
[0025] Example 2
[0026] The difference between this embodiment and embodiment 1 is that the toothed refractive glass plate 7 is mounted below the laser tube 6 by a fixing frame.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
