Description

Technical Field

[0001] This utility model relates to the field of embroidery technology, and more specifically, to an embroidery positioning device for embroidery machines. Background Technology

[0002] In the field of embroidery machine processing, precise positioning and secure clamping of fabric are crucial for ensuring the quality of embroidery patterns and preventing misalignment and wrinkles. In existing technologies, common fabric positioning devices typically feature clamping mechanisms (such as clamps, presser feet, or sliders) with fixed positions or limited linear guideways on a positioning plate. These mechanisms are often arranged along the edge of the positioning plate or pre-set parallel tracks to clamp the four corners or edges of the fabric. While this design provides a certain level of positioning effectiveness, its adjustment range is strictly limited by the pre-set tracks or fixed mounting points. Operators need to manually move each clamping mechanism to its pre-set track position or mounting point for fixation, according to the fabric dimensions.

[0003] The above positioning method is applicable to standard rectangular fabrics with sizes matching the preset positions, but its adaptability is very insufficient when facing embroidery needs with varying sizes, non-standard shapes (such as trapezoidal or polygonal scraps), or when maximizing the use of fabric width for flexible embroidery. Utility Model Content

[0004] To solve the above problems, this utility model provides an embroidery positioning device for embroidery machines.

[0005] This utility model provides an embroidery positioning device for an embroidery machine, comprising:

[0006] A positioning plate is located below the embroidery machine. The upper surface of the positioning plate is provided with a first sliding groove and a third sliding groove, which form an X-shaped groove structure.

[0007] The positioning mechanism consists of four slidably connected to the four ends of the X-shaped groove structure, and the positioning mechanism is used to press the fabric.

[0008] Optionally, the upper surface of the positioning plate is further provided with a second sliding groove, the second sliding groove being parallel to the long side of the positioning plate, and the X-shaped groove structure being symmetrical about the second sliding groove, with the two positioning mechanisms respectively slidably connected to the two ends of the second sliding groove.

[0009] Optionally, the positioning mechanism includes a slider and a pressure plate. One end of the slider is slidably connected to the first, second, or third slide groove, and the other end of the slider extends out of the upper surface of the positioning plate. The pressure plate is used to move up and down relative to the slider.

[0010] Optionally, the positioning mechanism further includes a spinning member, which is disposed on the slider and is drivenly connected to the pressure plate. When the spinning member rotates, the pressure plate moves up and down.

[0011] Optionally, the positioning mechanism further includes a flexible pressing unit disposed on the lower surface of the pressure plate. When the flexible pressing unit presses against the fabric, it applies a thrust to the fabric in a direction away from the center of the positioning plate.

[0012] Optionally, the flexible clamping unit includes an elastic rod and a rubber ball. One end of the elastic rod is connected to the bottom surface of the pressure plate, and the other end of the elastic rod is bent downward away from the center of the positioning plate and connected to the rubber ball.

[0013] Optionally, the flexible clamping unit includes an elastic rod and a rubber ball. One end of the elastic rod is connected to the bottom surface of the pressure plate, and the other end of the elastic rod is bent downward away from the center of the positioning plate and connected to the rubber ball.

[0014] The beneficial effects of this embroidery positioning device for embroidery machines are as follows: by setting a first sliding groove and a third sliding groove on the upper surface of the positioning plate, and making the first sliding groove and the third sliding groove form an X-shaped groove structure, the four positioning mechanisms can slide along the path of the X-shaped groove structure. Thus, the positions of the four positioning mechanisms can be flexibly adjusted according to the fabric placed on the positioning plate, so that the four positioning mechanisms press and position the four sides of the fabric respectively, thereby improving the stability of the fabric during embroidery.

[0025] This utility model embodiment provides an embroidery positioning device for an embroidery machine, applied to an embroidery machine 100, comprising:

[0026] Positioning plate 1 is located below embroidery machine 100. The upper surface of positioning plate 1 is provided with a first slide groove 11 and a third slide groove 13, which form an X-shaped groove structure.

[0027] Positioning mechanism 2: Four positioning mechanisms 2 are slidably connected to the four ends of the X-shaped groove structure, and the positioning mechanism 2 is used to press the fabric.

[0028] Specifically, the positioning plate 1 is integrally formed into a rectangular structure and is set below the embroidery needle of the embroidery machine 100. The first slide groove 11 and the third slide groove 13 can be integrally formed on the upper surface of the positioning plate 1, or they can be chiseled out on the upper surface of the positioning plate 1. The extension direction of the first slide groove 11 is along one of the diagonal directions of the positioning plate 1, and the extension direction of the third slide groove 13 is along the other diagonal direction of the positioning plate 1. The first slide groove 11 and the third slide groove 13 intersect each other to form an X-shaped groove structure. At this time, the center point of the X-shaped groove structure is also located at the center of the positioning plate 1.

[0029] In this optional embodiment, combined with Figure 1 As shown, by setting a first sliding groove 11 and a third sliding groove 13 on the upper surface of the positioning plate 1, and making the first sliding groove 11 and the third sliding groove 13 form an X-shaped groove structure, the four positioning mechanisms 2 can slide along the path of the X-shaped groove structure. In this way, the positions of the four positioning mechanisms 2 can be flexibly adjusted according to the fabric placed on the positioning plate 1, so that the four positioning mechanisms 2 press and position the four sides of the fabric respectively, thereby improving the stability of the fabric during embroidery.

[0030] Optionally, the upper surface of the positioning plate 1 is also provided with a second sliding groove 12, the second sliding groove 12 is parallel to the long side of the positioning plate 1, and the X-shaped groove structure is symmetrical about the second sliding groove 12, and the two positioning mechanisms 2 are respectively slidably connected to the two ends of the second sliding groove 12.

[0031] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, by adding a second slide groove 12 to the upper surface of the positioning plate 1, and the second slide groove 12 also having two slidingly arranged positioning mechanisms 2, it cooperates with the X-shaped groove structure to change from four-point pressing to six-point pressing, thereby further improving the positioning effect of the fabric.

[0032] Furthermore, the positioning mechanism 2 includes a slider 21 and a pressure plate 23. One end of the slider 21 is slidably connected to the first slide groove 11, the second slide groove 12 or the third slide groove 13, and the other end of the slider 21 extends out of the upper surface of the positioning plate 1. The pressure plate 23 is used to move up and down relative to the slider 21.

[0033] In this optional embodiment, combined with Figure 3 , Figure 4 and Figure 5 As shown, the slider 21 can slide in the first slide groove 11, the second slide groove 12 or the third slide groove 13, thereby flexibly adjusting the position of the positioning mechanism 2. When the pressure plate 23 moves downward, it can press against the fabric. When the pressure plate 23 moves upward, it can release the fabric.

[0034] Optionally, the positioning mechanism 2 further includes a spinning member 22, which is disposed on the slider 21 and is drivenly connected to the pressure plate 23. When the spinning member 22 rotates, the pressure plate 23 moves up and down.

[0035] Furthermore, the positioning mechanism 2 also includes a flexible pressing unit, which is located on the lower surface of the pressure plate 23. When the flexible pressing unit presses against the fabric, it applies a thrust to the fabric in a direction away from the center of the positioning plate 1.

[0036] Optionally, the flexible clamping unit includes an elastic rod 24 and a rubber ball 25. One end of the elastic rod 24 is connected to the bottom surface of the pressure plate 23, and the other end of the elastic rod 24 is bent downward away from the center of the positioning plate 1 and connected to the rubber ball 25.

[0037] In this optional embodiment, combined with Figure 3 , Figure 4 and Figure 5As shown, the elastic rod 24 can be made of a plastic material with a certain degree of flexibility. When the pressure plate 23 presses down and causes the rubber ball 25 to contact the upper surface of the fabric, since the elastic rod 24 bends downward in a direction away from the center of the positioning plate 1, the elastic rod 24 is further bent by the counter-thrust of the elastic rod 24. That is to say, the degree of bending of the elastic rod 24 increases, so that the rubber ball 25 not only exerts downward pressure on the upper surface of the fabric, but also exerts a thrust on the upper surface of the fabric away from the center of the positioning plate 1, thereby tightening the four sides of the fabric to a certain extent. And elastic compression is achieved through the elastic rod 24 and the rubber ball 25. When the embroidery needle pierces the fabric at high speed, it will generate a downward impact force on the local area. At this time, the rubber ball 25, which is located above the fabric and supported by the elastic rod 24, can undergo appropriate elastic deformation (compression). This deformation not only absorbs part of the impact energy, but more importantly, it ensures that the rubber ball 25 always applies gentle pressure to the fabric through the elastic rod 24 throughout the entire process of the needle tip piercing and lifting. The insertion of the embroidery needle can easily cause minor local deformation of the fabric fibers around the insertion point or attempt to move towards the needle hole. The continuous and gentle vertical pressure provided by the rubber ball 25 effectively "nails" the fabric to the working surface, significantly suppressing this tendency of local deformation and displacement, and fundamentally preventing the formation of micro-wrinkles centered on the needle hole. The tension force (pretension) applied to the four sides of the fabric provides a stable basic tension field for the fabric as a whole. This tension field works synergistically with the local pressure generated by the rubber ball 25. The edge tension prevents the fabric from loosening or shifting over a large area, while the elastic pressing point controls the microscopic stability of the core area of ​​the embroidery operation. The combination of the two allows the fabric surface to quickly return to a flat state when disturbed by needle insertion, making it less likely to produce permanent creases or wrinkles. Multiple sets of elastic rods 24 and rubber balls 25 are usually distributed above or around the embroidery area, allowing each rubber ball 25 to be independently adjusted according to the minor unevenness or thickness difference of the fabric below it, thereby providing a more uniform pressing effect over a larger area.

[0038] In summary, the overall tension provided by the four-sided tension, combined with the multi-point, dynamic, and adaptive local vertical pressure provided by the elastic rod 24 and the rubber ball 25, effectively counteracts the disturbance caused by the needle's piercing force during embroidery. This maximizes the flatness of the fabric in the embroidery area, significantly reducing the possibility of wrinkles and ensuring the quality and aesthetics of the embroidery.

[0039] Optionally, the spinning element 22 is a bolt, which is threaded onto the slider 21, and the bottom end of the bolt is rotatably connected to the pressure plate 23.

[0040] In this optional embodiment, the slider 21 has a threaded hole for bolt thread connection, and the pressure plate 23 is driven to move up and down by rotating the bolt.

[0041] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
