[0002] The omnidirectional chain stitch computer embroidery machine can embroider any chain stitch and towel stitch pattern, with various colors freely combined. The embroidered flowers, trees, animals, graphics, cartoons, etc., have the characteristics of layering, novelty, and strong three-dimensionality, and are very popular among consumers and designers.

[0003] In existing technologies, the feeding guide bracket of the universal chain embroidery machine mainly uses guide rings for guiding and feeding. However, the guide rings lack sufficient flexibility and versatility when feeding and guiding thread bundles of different sizes, making it difficult to achieve precise guidance. This can lead to the thread bundles easily deviating during the feeding process, thus affecting the effect and quality of the embroidery. Therefore, it is necessary to design a universal chain embroidery machine feeding guide bracket to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a universal chain-type embroidery machine feeding guide bracket, comprising:

[0007] The universal chain embroidery machine feeding bracket is equipped with an adjustment and replacement mechanism.

[0008] The adjustment and replacement mechanism includes a guide ring, a lead screw, a moving plate, a connecting plate, a splicing block, a sliding plate, a side plate, a spring, and guide balls;

[0009] The lead screw is threadedly connected to the moving plate. The moving plate is vertically slidably mounted on the feeding bracket of the universal chain embroidery machine. The connecting plate is fixedly connected to the guide ring and the splicing block. The splicing block is engaged with the moving plate. The sliding plate is slidably mounted on the guide ring. The side plate is fixedly connected to the sliding plate. The spring is fixedly mounted between the side plate and the guide ring. The guide ball is slidably mounted on the sliding plate.

[0010] A further feature of this invention is that the adjustment and replacement mechanism includes a hand lever, a branch lever, and a triangular extrusion plate, the branch lever being fixedly connected to the hand lever and the triangular extrusion plate, and a trapezoidal groove being provided on the slide plate.

[0011] A further feature of this invention is that the top of the feed bracket of the universal chain embroidery machine is provided with a movable hole, and the movable plate is vertically slidably installed in the movable hole.

[0012] By adopting the above technical solution, it is convenient for the movable plate to move vertically.

[0013] A further feature of this invention is that a base frame is fixedly installed at the bottom of the universal chain embroidery machine feeding bracket, and the lead screw is rotatably mounted on the base frame.

[0014] A further feature of this invention is that the movable plate has a splicing groove, and the splicing block is engaged with the splicing groove.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a universal chain-type feeding guide bracket for an embroidery machine, comprising:

[0031] The universal chain embroidery machine feeding bracket 1 is equipped with an adjustment and replacement mechanism. It should be noted that the guide ring 2 has sufficient flexibility and versatility when feeding and guiding wire bundles of different sizes, avoiding the wire bundles from shifting during the feeding process, ensuring the accuracy of the stitches during the embroidery process, and improving the embroidery quality.

[0032] The adjustment and replacement mechanism includes a guide ring 2, a lead screw 4, a moving plate 5, a connecting plate 6, a splicing block 7, a sliding plate 8, a side plate 9, a spring 10, and a guide ball 11;

[0033] The lead screw 4 is threadedly connected to the moving plate 5. The moving plate 5 is vertically slidably mounted on the feeding bracket 1 of the universal chain embroidery machine. The connecting plate 6 is fixedly connected to the guide ring 2 and the splicing block 7. The splicing block 7 is engaged with the moving plate 5. The slide plate 8 is slidably mounted on the guide ring 2. The side plate 9 is fixedly connected to the slide plate 8. The spring 10 is fixedly mounted between the side plate 9 and the guide ring 2. The guide ball 11 is slidably mounted on the slide plate 8.

[0034] With the above structure, the splicing block 7 on the connecting plate 6 is first spliced ​​with the moving plate 5. Then, the screw 4 is rotated so that the moving plate 5 drives the connecting plate 6 to move down, so that the splicing block 7 moves into the moving hole. This can limit the position of the connecting plate 5, making it convenient to quickly assemble the guide ring 2. At this time, by rotating the screw 4, it is also convenient to adjust the height of the guide ring 2.

[0035] Specifically, the adjustment and replacement mechanism also includes a hand lever 13, a branch lever 14 and a triangular extrusion plate 15. The branch lever 14 is fixedly connected to the hand lever 13 and the triangular extrusion plate 15, and a trapezoidal groove 12 is provided on the slide plate 8.

[0036] With the above structure, by holding the hand lever 13, the triangular extrusion plate 15 is moved into the trapezoidal groove 12. The inclined surface of the triangular extrusion plate 15 presses against the inclined surface of the trapezoidal groove 12, causing multiple guide balls 11 to move outward. This facilitates the passage of the wire harness. Then, the hand lever 13 is removed, and the multiple guide balls 11 are gathered together to guide the wire harness. Later, when dealing with wire harnesses of different sizes, the guide rings 2 can be quickly replaced. The positions of the trapezoidal grooves 12 on each guide ring 2 are corresponding, the difference being the length of the slide plate 8.

[0037] Specifically, the top of the universal chain embroidery machine feeding bracket 1 has a moving hole, and the moving plate 5 is vertically slidably installed in the moving hole. The bottom of the universal chain embroidery machine feeding bracket 1 is fixedly set with a base frame 3, and the screw 4 is rotatably installed on the base frame 3. The moving plate 5 has a splicing groove, and the splicing block 7 is engaged with the splicing groove. It should be noted that this facilitates docking.

[0038] Specifically, the bottom of the connecting plate 6 is in contact with the movable plate 5. It should be noted that the connecting plate 6 can be supported.

[0039] Specifically, multiple grooves are provided on the inner wall of the guide ring 2, the slide plate 8 is slidably installed in the groove, a side hole is provided on the side wall of the groove, the side plate 9 is slidably installed in the side hole, and the spring 10 is fixedly connected to the inner wall of the side hole. It should be noted that this facilitates the movement of the slide plate 8 and the side plate 9.

[0040] Working principle:

[0041] S1: During the guide ring installation and height adjustment stage, first align the splicing block 7 on the connecting plate 6 with the splicing groove on the moving plate 5 and clamp it in place to achieve the initial connection between the guide ring 2 and the moving plate 5. Then rotate the screw 4 on the base frame 3. Since the screw 4 is threadedly connected to the moving plate 5 and the moving plate 5 is vertically slidably installed in the moving hole of the universal chain embroidery machine feeding bracket 1, the rotation of the screw 4 will drive the moving plate 5 to move vertically along the moving hole, and then drive the guide ring 2 to rise and fall synchronously through the connecting plate 6, thereby adjusting the height of the guide ring 2 to adapt to different embroidery operation requirements. When the height of the guide ring 2 is determined, the splicing block 7 is completely moved into the moving hole to achieve stable positioning of the guide ring 2.

[0042] S2: In the wire harness guiding stage, under natural conditions, the spring 10 is in the extended state, pushing the side plate 9 to drive the slide plate 8 to gather towards the center along the groove on the inner wall of the guide ring 2. The guide balls 11 on the multiple slide plates 8 approach each other to form a guide channel that is compatible with wire harnesses of conventional sizes. When the wire harness passes through the guide ring 2, the guide balls 11 contact the wire harness and roll, reducing the friction when the wire harness moves. At the same time, they are all limited to prevent them from deviating and ensure feeding accuracy.

[0043] S3: When it is necessary to adapt to wire harnesses of different sizes, the guide ring 2 can be temporarily adjusted or replaced by adjusting the mechanism. During temporary adjustment, hold the hand lever 13 and insert the triangular extrusion plate 15 at the end of the branch lever 14 into the trapezoidal groove 12 of the slide plate 8. Use the inclined surface of the triangular extrusion plate 15 to press the inclined surface of the trapezoidal groove 12, pushing the slide plate 8 to overcome the elastic force of the spring 10 and move it to the outside of the groove, increasing the channel diameter formed by the guide ball 11, making it easier for thicker wire harnesses to pass through. After removing the hand lever 13, the spring 10 returns to its original position, and the guide ball 11 gathers again to adapt to the wire harness. If it is necessary to adapt to a specific size wire harness for a long time, the screw 4 can be rotated in the opposite direction to raise the moving plate 5, and the splicing block 7 can be removed from the splicing groove of the moving plate 5. Remove the original guide ring 2, replace it with a guide ring 2 with a slide plate 8 of the corresponding length, and then fix it according to the installation process to meet the guidance requirements of different size wire harnesses and improve the versatility of the device.

[0044] The above provides a detailed description of the universal chain-type feeding guide bracket for an embroidery machine. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
