[0028] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and an embroidery positioning device for an embroidery machine involved in the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] Referring to Figure 1-7 , the present utility model provides an embroidery positioning device for an embroidery machine, including a positioning frame 1. A strip-shaped adjustment hole 2 is opened on the front surface of the positioning frame 1. The inner wall of the strip-shaped adjustment hole 2 is rotatably connected to a vertical lead screw 3. An installation groove is opened on the front surface of the positioning frame 1, and a lifting motor 10 is fixedly arranged on the inner wall of the installation groove. The output shaft of the lifting motor 10 extends into the interior of the strip-shaped adjustment hole 2 and is fixedly connected to the bottom end of the vertical lead screw 3.

[0030] The surface of the vertical lead screw 3 is threadedly connected to a first adjustment block 4. The front surface of the first adjustment block 4 is fixedly connected to a horizontal positioning box 5. The inner wall of the horizontal positioning box 5 is rotatably connected to a horizontal lead screw 6. A horizontal motor 11 is fixed to the right end of the horizontal positioning box 5. The output shaft of the horizontal motor 11 extends into the interior of the horizontal positioning box 5 and is fixedly connected to the right end of the horizontal lead screw 6. The surface of the horizontal lead screw 6 is threadedly connected to a second adjustment block 7. The front surface of the second adjustment block 7 is fixedly connected to a positioning mechanism 8, and the positioning mechanism 8 is used for positioning the fabric.

[0031] Through the above technical solution, the lifting motor 10 can be used to drive the vertical lead screw 3 to rotate, and then drive the first adjusting block 4 to move up and down inside the strip-shaped adjusting hole 2. By setting the horizontal motor 11, the horizontal motor 11 can be used to drive the second adjusting block 7 to move horizontally inside the horizontal positioning box 5, so as to facilitate the adjustment of the height and horizontal position of the positioning mechanism 8 during embroidery.

[0032] The positioning mechanism 8 includes a U-shaped fixed frame 801, and clamping assemblies 9 are arranged on both sides of the fixed frame 801. The clamping assemblies 9 are used to clamp and fix both ends of the fabric.

[0033] The clamping assembly 9 includes two clamping plates 901. Two limiting rods 902 are fixedly connected to the side surfaces of the two clamping plates 901. Limiting through holes matching the limiting rods 902 are formed on the side surface of the fixed frame 801. The limiting rods 902 are slidably connected to the surface of the fixed frame 801 through the limiting through holes. Rubber anti-slip pads 905 are fixedly arranged on the opposite surfaces of the clamping plates 901 and the fixed frame 801.

[0034] Through the above technical solution, a compression spring 903 is sleeved on the surface of the limiting rod 902. A limiting circular plate 904 is fixedly connected to one end of the limiting rod 902 away from the clamping plate 901. One end of the compression spring 903 is fixedly connected to the surface of the fixed frame 801, and the other end of the compression spring 903 is fixedly connected to the surface of the limiting circular plate 904.

[0035] It should be noted that by arranging the clamping assemblies 9 on both sides of the fixed frame 801, when the fabric is limited and fixed, the compression spring 903 can be used to drive the clamping plates 901 to clamp and fix both ends of the fabric, so as to further improve the stability of the fabric on the surface of the fixed frame 801, avoid the position deviation of the fabric during the embroidery process, and improve the stability of embroidery.

[0036] Two stoppers are fixedly connected to the surface of the fixed frame 801. A bidirectional lead screw 802 is rotatably connected between the two stoppers. A driven bevel gear 809 is fixedly connected to the middle of the bidirectional lead screw 802. A fixed plate is fixedly connected to the lower surface of the fixed frame 801. An adjusting knob 810 is rotatably connected to the surface of the fixed plate. A driving bevel gear 811 is fixedly connected to the top end of the adjusting knob 810. The driving bevel gear 811 meshes with the driven bevel gear 809.

[0037] Through the above technical solution, two moving plates 803 are threadedly connected to the surface thread of the bidirectional lead screw 802. Arc-shaped bases 804 are fixedly connected to the front surfaces of the two moving plates 803. A limiting shell 805 is fixedly connected to the side surface of the moving plate 803. A threaded rod 806 is rotatably connected to the inner wall of the limiting shell 805. A lifting block 807 is threadedly connected to the surface of the threaded rod 806. An arc-shaped pressing plate 808 is fixedly connected to the front surface of the lifting block 807. The position of the arc-shaped pressing plate 808 corresponds to that of the arc-shaped base 804, and the radius of the arc-shaped pressing plate 808 is greater than the radius of the arc-shaped base 804. After the arc-shaped pressing plate 808 descends, it can cause dislocation to the arc-shaped base 804, thereby using the dislocation to clamp and fix the fabric. A circular ring shape is formed between the two corresponding arc-shaped bases 804 and the two arc-shaped pressing plates 808.

[0038] Through the above technical solution, the driving bevel gear 811 can be driven to rotate by rotating the adjusting knob 810, and then the driven bevel gear 809 and the bidirectional lead screw 802 are driven to rotate. Then, the distance between the two arc-shaped bases 804 can be adjusted by using the bidirectional lead screw 802, which is suitable for positioning fabrics of different sizes. The threaded rod 806 can be driven to rotate by rotating the adjusting nut, and then the lifting block 807 is driven to move downward inside the limiting shell 805, thereby driving the arc-shaped pressing plate 808 to move downward.

[0039] It should be noted that by providing a positioning mechanism 8 on the surface of the positioning frame 1, when embroidering the fabric with a computer embroidery machine, the bottom of the fabric can be limited and supported by the two arc-shaped bases 804, and then the two arc-shaped pressing plates 808 move downward to form a position stagger with the arc-shaped bases 804, thereby squeezing the fabric, and thus tightening and fixing the periphery of the embroidery area of the fabric, so as to facilitate the embroidery machine to embroider on the fabric surface.

[0040] An L-shaped limiting plate 812 is fixedly connected to the surface of the arc-shaped base 804. A limiting insertion plate 813 is fixedly connected to the front end of the arc-shaped pressing plate 808. The limiting insertion plate 813 is matched with the L-shaped limiting plate 812. Through the above technical solution, when the arc-shaped pressing plate 808 descends to the position of the arc-shaped base 804, the limiting insertion plate 813 can be inserted between the L-shaped limiting plate 812 and the arc-shaped base 804, thereby using the L-shaped limiting plate 812 to limit the limiting insertion plate 813, and further improving the firmness between the arc-shaped pressing plate 808 and the arc-shaped base 804, and at the same time enabling the two arc-shaped pressing plates 808 to maintain a stable distance.

[0041] A guide plate 814 is fixedly connected to the front end of the arc-shaped base 804, and a guide rod 815 is fixedly connected to the front end of the fixed frame 801. A guide through hole matching the guide rod 815 is formed on the surface of the guide plate 814. The guide plate 814 is slidably connected to the surface of the guide rod 815 through the guide through hole. A support spring 816 is sleeved on the surface of the guide rod 815. One end of the support spring 816 is fixedly connected to the side surface of the guide plate 814, and the other end of the support spring 816 is fixedly connected to the surface of the guide rod 815.

[0042] It should be noted that by providing the guide rod 815 and the support spring 816 at the front end of the arc-shaped base 804, not only can the guide plate 814 be used to move on the surface of the guide rod 815, but also the support spring 816 can be used to support and limit the front end of the arc-shaped base 804, so that a certain supporting force is maintained at the front ends of the two arc-shaped bases 804, thereby facilitating the maintenance of the distance between the two arc-shaped bases 804.

[0043] Working principle: First, lay the fabric flat on the surface of the fixed frame 801 so that the embroidery area is directly above the two arc-shaped bases 804. Then, place the two ends of the fabric between the clamping plate 901 and the fixed frame 801 respectively, and use the compression spring 903 to drive the clamping plate 901 to clamp and fix both sides of the fabric. Then, use the threaded rod 806 to drive the two arc-shaped pressing plates 808 to move downward to intersect with the arc-shaped base 804, so as to position the fabric by using the arc-shaped pressing plate 808 and the arc-shaped base 804, and keep the fabric in the embroidery area tight and flat, which is beneficial to the embroidery operation on the fabric.

[0044] Finally, it should be noted that in the attached drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
