DETAILED DESCRIPTION

[0020] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a sewing machine with a quick positioning function, comprising a workbench 1, a rotating motor 2 is provided on the bottom wall of the workbench 1, a needle disc 3 is plugged into the output end of the rotating motor 2, a supporting base 4 is welded on one side of the top of the workbench 1, a sewing machine unit 5 is threadedly connected to the top of the supporting base 4, a servo motor 6 is installed on the internal thread of the sewing machine unit 5, a sewing needle 7 is plugged into the output end of the servo motor 6, a support rod 8 is threadedly connected to the front side of the bottom of the workbench 1, and a positioning mechanism 9 is provided on the top of the support rod 8.

[0022] In this embodiment, Figure 2 As shown, a groove 101 is provided in the middle of the top of the workbench 1, and a rotary motor 2 is threadedly connected to the bottom wall of the groove 101; it should be noted that a groove 101 is provided at the center of the top of the workbench 1 in the utility model, and the bottom wall of the groove 101 can be used to threadably connect the rotary motor 2 to fix the position of the entire rotary motor 2, and a needle disk 3 is also plugged into the output end of the rotary motor 2. When the rotary motor 2 is started, its output end will drive the needle disk 3 to rotate together, thereby automatically transferring the garment pieces to the sewing disk unit 5, and sewing the two garment pieces together through the sewing needle 7. During this process, the rotary motor 2 will generate mechanical vibrations, and the setting of the groove 101 can fix the rotary motor 2 to prevent it from tipping over during operation.

[0023] In this embodiment, Figure 2 and Figure 3 As shown, the rotary motor 2 and the needle disk 3 plugged into its output end together constitute a rotary mechanism; it should be noted that, in the use of the traditional sewing machine, after the operator manually pushes the garment piece against the thimble 301 provided on the needle disk 3, the entire needle disk 3 is pushed by hand to rotate the garment piece to the sewing disk unit 5 for sewing operation. The operation process is time-consuming and labor-intensive, and the efficiency is not high. In the utility model, a rotary motor 2 is plugged into the middle part of the bottom of the needle disk 3, and the two constitute a rotary mechanism. In specific operation, the operator only needs to push the garment piece into the deep of the thimble 301 first, and then start the rotary motor 2 to make its output end start to rotate and drive the needle disk 3 plugged therein to rotate together. During this period, the needle disk 3 will be transferred to the sewing disk unit 5 together with the garment piece positioned by its thimble 301, and the sewing operation of the two garment pieces will be completed through the sewing needle 7. The whole process is completed by the machine itself, and no manual push is required, which speeds up the sewing speed and improves production efficiency.

[0024] In this embodiment, Figure 3 and Figure 4As shown, a number of thimbles 301 are evenly distributed on the annular outer wall of the needle disk 3; it should be noted that when using the sewing disk machine of the present invention, the operator needs to first place the garment piece in the gap between the positioning mechanism 9 and the thimble 301, and then automatically push the garment piece into the outer wall of the needle body of the thimble 301 by starting the positioning mechanism 9. At the same time, the operator starts the rotating motor 2, so that the rotating motor 2 drives the entire needle disk 3 to start rotating, thereby rotating the garment piece abutting against the outer wall of the needle body of the thimble 301 to the position of the sewing disk unit 5, and completing the sewing operation between different garment pieces through the sewing needle 7. The thimbles 301 distributed on the annular outer wall of the needle disk 3 have different specifications, which are divided into two types of coarse and fine. When sewing, the operator can first select the appropriate needle disk 3 according to the size of the stitches.

[0025] In this embodiment, Figure 1 and Figure 5 As shown, the positioning mechanism 9 is composed of a fixed box 901, a driving motor 902, a connecting shaft 903, a cam 904, an elastic touch rod 905 and a sleeve 906, wherein the top wall of the fixed box 901 is clamped with the driving motor 902, and the output end of the driving motor 902 is plugged with one end of the connecting shaft 903, and the cam 904 is sleeved on the other end of the connecting shaft 903, and a sleeve 906 is provided on the outer wall of the fixed box 901 close to the needle disk 3, and the elastic touch rod 905 is slidably connected to the inner wall of the sleeve 906; it should be noted that in the use of traditional sewing machines, the operator is required to manually push the garment piece into the outer wall of the needle body of the ejector 301, which requires the operator's own proficiency and eyesight. Because it is completely manually operated, it is also greatly affected by interference factors, and it is easy to have inaccurate displacement of the garment piece. The utility model designs a positioning mechanism 9, and its specific operation is that the operator first places the garment piece between the gap between the sleeve 906 and the ejector pin 301, and then starts the driving motor 902, so that its output end drives the connecting shaft 903 and the cam 904 sleeved on the bottom end of the connecting shaft 903 to rotate together. During the rotation of the cam 904, its protruding portion will contact the elastic contact rod 905 close to the outside of the sleeve 906, and push the elastic contact rod 905 toward the ejector pin 301, so that the elastic contact rod 905 moves horizontally along the inner wall of the sleeve 906 until it penetrates into the gap between the two ejector pins 301, and can automatically push the garment piece into the outer wall of the needle body of the ejector pin 301, quickly completing the abutment positioning, and because it is automatically operated by the machine, it is more time-saving and labor-saving, and avoids the situation of the garment piece abutment position offset.

[0026] In this embodiment, Figure 5As shown in the figure, the diameter of the elastic feeler rod 905 is smaller than the gap between the two ejector pins 301 provided on the needle plate 3, and its full length can penetrate into the deepest part of the gap between the ejector pins 301; it should be noted that when the operator starts the driving motor 902 to drive the connecting shaft 903 and the cam 904 to rotate together, the protruding portion of the cam 904 contacts the head end of the elastic feeler rod 905, which will push the elastic feeler rod 905 laterally, so that it slides out along the inner wall of the sleeve 906 and extends to the gap between the two ejector pins 301. During this period, because the diameter of the elastic touch rod 905 is smaller than the gap between the two ejector pins 301, and the elastic touch rod 905 is pushed by the cam 904, the extended length can also completely penetrate into the deepest part of the gap between the ejector pins 301. Therefore, when the elastic touch rod 905 is moved horizontally and inserted straight, it can smoothly penetrate into the deepest part of the gap between the two ejector pins 301 without being blocked, so that the garment piece can be automatically pushed into the outer wall of the needle body of the ejector pin 301 easily.

[0027] The use method and advantages of the utility model: When the sewing machine with a rapid positioning function is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the operator first manually places the garment piece between the gap between the sleeve 906 and the ejector pin 301, and then starts the drive motor 902 and the rotary motor 2 at the same time, so that the output end of the drive motor 902 drives the connecting shaft 903 and the cam 904 sleeved at the bottom end of the connecting shaft 903 to rotate together. During the rotation of the cam 904, its protruding portion contacts the elastic feeler rod 905 close to the outer side of the sleeve 906, and pushes the elastic feeler rod 905 toward the direction of the ejector pin 301, so that the elastic feeler rod 905 moves horizontally along the inner wall of the sleeve 906 until it penetrates into the two sides. The gap between the thimbles 301 can automatically push the garment piece into the outer wall of the needle body of the thimble 301. At the same time, the output end of the rotating motor 2 will also drive the needle disk 3 connected thereto to rotate. During this period, the needle disk 3 will bring the garment piece positioned by its thimble 301 through the positioning mechanism 9, thereby completing the automatic pushing of the garment piece, and transferring the abutted garment piece to the sewing disk unit 5 along the rotation direction of the needle disk 3, and completing the sewing operation of the two garment pieces through the sewing needle 7. The whole process is completed by the machine itself, without the need for manual push, which speeds up the sewing speed and improves the production efficiency.
