When the support rod moves out of its perpendicular position to the magnet, it resets under the action of the several first elastic cords, continuing to support the fabric and ensuring the accuracy and effect of the Miao embroidery.

Description

Technical Field

[0001] This invention relates to the field of Miao embroidery technology, specifically a positioning and fixing frame for Miao embroidery fabric and its usage method. Background Technology

[0002] With the advancement of technology and the continuous development of the embroidery industry, modern automated embroidery machines have been widely used in the Miao embroidery production process, greatly improving the efficiency of Miao embroidery and reducing labor costs.

[0003] When using an embroidery machine to perform Miao embroidery on a garment, a garment fixing frame is needed to position the part of the garment to be embroidered (that is, the bottom frame is inserted into the garment and adjusted to the correct position, and then the pressing frame is fastened to position the part of the garment to be embroidered). However, due to the influence of the fabric's own weight, the positioned embroidered part of the fabric will inevitably sag, especially with softer and more elastic fabrics, where this sag is more obvious and seriously affects the accuracy and effect of Miao embroidery.

[0004] Therefore, this invention proposes a fabric Miao embroidery positioning and fixing frame and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fabric Miao embroidery positioning and fixing frame and its usage method to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A Miao embroidery positioning and fixing frame for fabric includes a base frame and a pressure frame that cooperates with the base frame to position the Miao embroidery part of the garment. The base frame has walking grooves on both sides to avoid the rotation of the shuttle box when the fixing frame moves. Multiple strips are arranged in the base frame, and multiple support rods are arranged on each strip. Several first elastic ropes are provided between the support rods and the strips, and the rod section below the strip is provided with a limiting piece.

[0008] The fixing frame also includes a magnet on the embroidery machine body and directly opposite the shuttle box. The magnet is located below the bottom frame. Each support rod has an iron block at its lower end that can be attracted by the magnet. The projected area of ​​the magnet is larger than the projected area of ​​the shuttle box. In its natural state, the upper end of each support rod is flush with the upper side of the shuttle box under the action of the limiting plate and several first elastic ropes.

[0009] In one alternative embodiment: a ring-shaped electromagnet is embedded in the bottom frame, and a ring-shaped iron component is embedded in the pressure frame for adsorption and engagement with the ring-shaped electromagnet. The inner edge of the pressure frame is provided with a pressing protrusion for pressing the fabric, so that when the bottom frame and the pressure frame are engaged to position the fabric, the bottom side of the fabric is flush with the upper side of the shuttle box. The inner edge of the upper side of the bottom frame and the lower side of the pressing protrusion on the pressure frame are both rounded. The bottom frame is provided with a control button for controlling the on and off of the ring-shaped electromagnet.

[0010] In one alternative: the bottom frame has an inner cavity, and the inner cavity has a mounting component that can move up and down. The mounting component has at least two positioning pins, and the positioning pins can penetrate the fabric as the mounting component moves up. The pressure frame has positioning slots that correspond to and fit the positioning pins.

[0011] In one alternative embodiment: a through groove running from top to bottom is provided on one side of the inner cavity; an operating rod passing through the through groove is provided on the mounting component; several second elastic ropes are provided between the mounting component and the bottom side of the inner cavity; a connecting rod is provided on one side of the inner cavity; a baffle is provided at one end of the connecting rod inside the inner cavity; a touch-sensitive element is provided at the other end outside the inner cavity, which is directly opposite the control button; at least one elastic telescopic rod is provided between the connecting rod and the cavity wall of the inner cavity; and the side of the mounting component away from the operating rod is inclined.

[0012] In one alternative embodiment: the elastic telescopic rod includes a cylinder and a column that is inserted into the cylinder, wherein a spring is provided in the cylinder.

[0013] A method of using a fabric Miao embroidery positioning and fixing frame employing any of the above technical solutions includes the following steps:

[0014] S1: Place the garment with the embroidery side facing up on the bottom frame and refine the embroidery area. Then flatten the fabric on the bottom frame and fasten the bottom frame to position the embroidery part of the garment.

[0015] S2: The fabric Miao embroidery area is supported by evenly distributed support rods to prevent it from sagging. When the support rod moves to be perpendicular to the magnet, the magnet will attract the iron block corresponding to the support rod, thereby causing the support rod to move down to avoid the rotary shuttle box. When the support rod moves out to be perpendicular to the magnet, the support rod will be reset under the action of several first elastic ropes and continue to support the fabric.

[0016] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0017] Evenly distributed support rods support the Miao embroidery area of ​​the fabric to prevent it from sagging. The fixing frame moves in the X and Y directions, causing all the support rods to move simultaneously. When the support rod moves to be perpendicular to the magnet, the magnet will attract the iron block corresponding to the support rod, thereby causing the support rod to move downward to avoid the rotary shuttle box, ensuring that the fixing frame can move normally. When the support rod moves out of being perpendicular to the magnet, the support rod will be reset by the action of several first elastic ropes, continuing to support the fabric and ensuring the accuracy and effect of Miao embroidery.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Please see Figures 1-4 A Miao embroidery positioning and fixing frame for fabric includes a base frame 1 and a pressing frame 2 that cooperates with the base frame 1 to position the Miao embroidery part of the garment. The base frame 1 has walking grooves 23 on both sides for avoiding the rotation of the shuttle box when the fixing frame moves. Multiple strips 4 are arranged in the base frame 1. Multiple support rods 3 are arranged on each strip 4. Several first elastic ropes 6 are provided between the support rods 3 and the strips 4. The rod section of the support rod 3 located below the strips 4 is provided with a limiting piece 5.

[0032] The fixing frame also includes a magnet 8 installed on the embroidery machine body and directly opposite the shuttle box. The magnet 8 is located below the bottom frame 1. Each support rod 3 has an iron block 7 at its lower end that can be attracted by the magnet 8. The projected area of ​​the magnet 8 is larger than the projected area of ​​the shuttle box. In its natural state, the upper end of each support rod 3 is flush with the upper side of the shuttle box under the action of the limiting piece 5 and several first elastic ropes 6.

[0033] The bottom frame 1 is connected to the embroidery frame drive mechanism of the embroidery machine. During operation, the fixed frame is driven by the embroidery frame drive mechanism to move continuously in the X and Y directions to carry out the machine embroidery process. By setting the walking groove 23, the rotary hook box can enter the inside of the bottom frame 1 to carry out embroidery without interfering with the movement of the fixed frame in the X and Y directions.

[0034] First, place the garment with the embroidery side facing up onto the base frame 1 and refine the embroidery area. Then, flatten the fabric on the base frame 1 and fasten it onto the base frame 1 to position the embroidery area of ​​the garment. The fabric embroidery area is supported by evenly distributed support rods 3 to prevent it from sagging. The fixed frame moves in the X and Y directions, causing all support rods 3 to move simultaneously. When the support rod 3 moves to be perpendicular to the magnet 8, the magnet 8 will attract the iron block 7 corresponding to the support rod 3, thereby causing the support rod 3 to move down to avoid the rotary shuttle box and ensure that the fixed frame can move normally. When the support rod 3 moves out to be perpendicular to the magnet 8 (i.e., the corresponding iron block 7 is separated from the magnet 8), the support rod 3 will be reset under the action of several first elastic ropes 6, continuing to support the fabric and ensuring the accuracy and effect of the embroidery.

[0035] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6 In one embodiment of the present invention, an annular electromagnet 10 is embedded on the bottom frame 1, and an annular iron part 12 for adsorption and cooperation with the annular electromagnet 10 is embedded on the pressure frame 2. The inner edge of the pressure frame 2 is provided with a pressing protrusion 13 for pressing the fabric, so that when the bottom frame 1 and the pressure frame 2 cooperate to position the fabric, the bottom side of the fabric is flush with the upper side of the shuttle box. The inner edge of the upper side of the bottom frame 1 and the lower side of the pressing protrusion 13 on the pressure frame 2 are rounded. The bottom frame 1 is provided with a control button 20 for controlling the on and off of the annular electromagnet 10.

[0036] The base frame 1 and the pressing frame 2 are magnetically attached. After adjusting the Miao embroidery area of ​​the garment, the pressing frame 2 is pressed onto the base frame 1 and the ring electromagnet 10 is energized by the control button 20. After being energized, the ring electromagnet 10 becomes magnetic and attracts the ring iron part 12, thereby quickly pressing and positioning the Miao embroidery area of ​​the garment. This is convenient and quick, and can also avoid leaving indentations on the garment. In addition, the lower corners of the inner edge of the upper side of the base frame 1 and the pressing material protrusion 13 on the pressing frame 2 are rounded to avoid leaving indentations on the garment.

[0037] It should be noted that, in order to power the ring electromagnet 10, an independent power supply component (such as a rechargeable battery or electric battery) can be set on the bottom frame 1, or an external power supply can be used. This embodiment does not limit this.

[0038] Please see Figure 5 , Figures 7-9 In one embodiment of the present invention, the bottom frame 1 is provided with an inner cavity 9, and the inner cavity 9 is provided with a mounting member 15 that can move up and down. The mounting member 15 is provided with at least two positioning pins 24, and the positioning pins 24 can penetrate the fabric as the mounting member 15 moves up. The pressure frame 2 is provided with positioning slots 11 that correspond to and are adapted to the positioning pins 24.

[0039] The inner cavity 9 has a through groove 22 running from top to bottom on one side. The mounting member 15 has an operating rod 21 passing through the through groove 22. Several second elastic ropes 18 are provided between the mounting member 15 and the bottom side of the inner cavity 9. A connecting rod 17 passes through one side of the inner cavity 9. The end of the connecting rod 17 inside the inner cavity 9 has a baffle 14, and the end outside the inner cavity 9 has a touch-sensitive element 19 facing the control button 20. At least one elastic telescopic rod 16 is provided between the connecting rod 17 and the cavity wall of the inner cavity 9. The side of the mounting member 15 away from the operating rod 21 is inclined.

[0040] Because the garment fabric obstructs the view, the pressure frame 2 cannot be aligned and pressed onto the bottom frame 1 in one go. Usually, after the pressure frame 2 contacts the bottom frame 1 through the garment fabric, it needs to be moved and adjusted to align and fit with the bottom frame 1. When the pressure frame 2 is moved, it pulls on the garment fabric, causing the originally flattened Miao embroidery area to shift and move, requiring readjustment. To solve this problem, in this implementation, after adjusting and flattening the Miao embroidery area of ​​the garment, the operator moves the mounting part 15 upward by holding the operating lever 21. When the mounting part 15 moves upward to contact the baffle 14, the inclined side of the mounting part 15 will first move away from the mounting part 15 against the baffle 14. When the mounting part 15 moves upward to the point where its bottom side is flush with the upper side of the baffle 14, the baffle 14 is reset under the action of the elastic telescopic rod 16, thereby restricting the positioning of the mounting part 15. At this time, the positioning pins 24 all penetrate the fabric. (It should be noted that the path length of the pressing part 19 moving towards the control button 20 during this process is insufficient to trigger the control.) Button 20 (the positioning pin 24 is of similar thickness to a textile needle and will not cause substantial puncture damage to the fabric), then lift the pressure frame 2 horizontally and make the positioning slot 11 perpendicular to the positioning pin 24. Maintain this state and release the pressure frame 2. The positioning pin 24 is inserted into the corresponding positioning slot 11. Multiple positioning pins 24 restrict the pressure frame 2 to prevent it from shifting during the lowering process, so that the pressure frame 2 is accurately aligned and pressed onto the bottom frame 1 in one go without repeated adjustments. After pressing, press the contact element 19 until the control button 20 is triggered, so that the annular electromagnet 10 is energized to magnetically fix the pressure frame 2. During the process of pressing the contact element 19 to trigger the control button 20, the connecting rod 17 will be pushed to move, thereby driving the baffle 14 to move away from the mounting part 15 and finally detach from the mounting part 15. When the baffle 14 detaches and no longer restricts the mounting part 15, the mounting part 15 is reset under the action of several second elastic ropes 18, thereby driving multiple positioning pins 24 to retract and reset.

[0041] Furthermore, in this embodiment, the elastic telescopic rod 16 includes a cylindrical body 1601 and a column 1602 that is inserted into the cylindrical body 1601, and a spring 1603 is provided in the cylindrical body 1601.

[0042] The present invention also provides a method for using the fabric Miao embroidery positioning and fixing frame employing any of the above technical solutions, comprising the following steps:

[0043] S1: Place the garment with the embroidery side facing up onto the base frame 1 and refine the embroidery area. Then flatten the fabric on the base frame 1 and fasten the base frame 1 to position the embroidery part of the garment.

[0044] S2: The Miao embroidery area of ​​the fabric is supported by evenly distributed support rods 3 to prevent it from sagging. When the support rod 3 moves to be perpendicular to the magnet 8, the magnet 8 will attract the iron block 7 corresponding to the support rod 3, thereby driving the support rod 3 to move down to avoid the rotary shuttle box. When the support rod 3 moves out to be perpendicular to the magnet 8, the support rod 3 will be reset under the action of several first elastic ropes 6 to continue to support the fabric.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
