[0002] Embroidery machines enable traditional hand embroidery to be carried out at high speed and efficiency, and can achieve the requirements of "multi-layer, multi-functional, uniform and perfect" that hand embroidery cannot achieve. It is an electromechanical product that embodies a variety of high-tech features. The bobbin thread machine is specially used to evenly wind the sewing thread onto the bobbin, providing the bottom stitch for sewing. Therefore, by working together with the bobbin thread machine and the embroidery machine, the function of automatic embroidery on the fabric can be realized.

[0003] However, existing bobbin thread machines lack the ability to position bobbins of different diameters. Therefore, when using bobbins of varying diameters, the fine thread on the surface of the bobbin is pulled, causing the bobbin to rotate excessively and wobbly. Furthermore, the bobbin thread machine lacks the ability to store and retrieve various tools, thus affecting the efficiency of structural replacement or maintenance during retrieval. To address these issues, we provide an automatic bobbin thread machine for embroidery to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic embroidery bobbin thread machine, which can position bobbins of different diameters by moving the expansion bar inside the strip opening.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 5 This utility model is an automatic embroidery bobbin thread machine. By moving the extension bar 4 inside the strip opening 203, it can position bobbins of different diameters. At the same time, the storage box 3 moves in the drawer opening 102 to store some spare structures and maintenance tools, which is convenient for subsequent structure replacement or maintenance.

[0027] Specifically, the main body of the bobbin thread machine is 1; a wire frame 2 is provided on the upper end face of the bobbin thread machine body 1, and a circular block 201 connected to the upper end face of the wire frame 2 is fixed on the lower end face of the wire frame 2. Two strip-shaped openings 203 are evenly distributed around the perimeter on the surface of the wire frame 2. An expansion strip 4 is provided inside each of the strip-shaped openings 203. A drawer opening 102 is provided on the left side wall of the bobbin thread machine body 1. A storage box 3 is slidably inserted into the drawer opening 102. A T-shaped opening 101 is provided at the part of the upper end face of the bobbin thread machine body 1 that connects with the circular block 201. A T-shaped block 202 that cooperates with the interior of the T-shaped opening 101 is fixed on the lower end face of the circular block 201.

[0028] The operation process of this embodiment is as follows: With the above structure, when it is necessary to position spools of different diameters, the spools are directly fitted onto the wire frame 2, and the extension bar 4 is controlled to move outward inside the strip opening 203, so that the surface of the extension bar 4 will contact the inner wall of the spool. By gradually pushing the extension bar 4, the extension bar 4 and the spool become increasingly close, thereby realizing that spools of different diameters are fitted onto the wire frame 2. At the same time, when it is necessary to store some spare spools or maintenance tools, the storage box 3 can be taken out from inside the drawer opening 102, and various tools can be put into the storage box 3. The storage box 3 is then reset to facilitate the storage of tools. At the same time, when the thread cutting machine is working, it will pull the thin line on the spool, thereby driving the spool to rotate, thereby driving the wire frame 2 to rotate. The T-shaped block 202 is located in the T-shaped opening 101, thereby ensuring the stable rotation of the wire frame 2.

[0029] Example 2

[0030] Please see Figure 3 , Figure 4 and Figure 5 Based on Example 1, the positioning rod 401 is limited by the positioning hole 204 to ensure that the extension strip 4 will not be misaligned during the movement.

[0031] Specifically, the wire frame 2 has two limiting holes 206 that communicate with the inside of the strip opening 203. The wire frame 2 located above and below each limiting hole 206 has a positioning hole 204 that communicates with the inside of the strip opening 203. The inner end of each limiting hole 206 has a moving hole 207. The side wall of the extension strip 4 is fixed with two positioning rods 401 that are respectively inserted into the positioning holes 204. The side wall of the extension strip 4 is fixed with a movable rod 402 that passes through the inside of the limiting hole 206. The end face of the movable rod 402 is fixed with a compression plug 403 located inside the moving hole 207.

[0032] The operation process of this embodiment is as follows: when the expansion bar 4 moves inside the strip opening 203, the expansion bar 4 will drive the positioning rod 401 to move inside the positioning hole 204. The positioning rod 401 is limited by the positioning hole 204 to ensure that the expansion bar 4 slides stably in the strip opening 203. At the same time, the expansion bar 4 will synchronously drive the movable rod 402 to move the extrusion plug 403 in the moving hole 207.

[0033] Example 3

[0034] Please see Figure 3 , Figure 4 and Figure 5 Based on Example 1, the screw 5 rotates in the screw hole 208 to facilitate the movement of the extension strip 4 and ensure the stable movement of the extension strip 4.

[0035] Specifically, the interior of the circular block 201 has two sets of movable holes 209 symmetrically arranged along its circumference. The surface wall of the circular block 201 has two screw holes 208 that are respectively connected to the interior of the movable holes 209. The movable hole 207 is connected to the corresponding movable hole 209 through the curved hole 205 opened inside the wire frame 2. The screw holes 208 are all screwed with screws 5. One end of the screw 5 is fixed to the piston block 501 inside the movable hole 209. The movable hole 209 between the piston block 501 and the curved hole 205 is provided with a spring 6. Both ends of the spring 6 are fixed with washers 601, and the washers 601 abut against the piston block 501 and the inner end face of the movable hole 209 respectively.

[0036] The operation process of this embodiment is as follows: When it is necessary to control the movement of the extension bar 4 inside the strip opening 203, the screw 5 can be controlled to rotate inside the screw hole 208. Then, the screw 5 will control the piston block 501 to move in the movable hole 209, thereby compressing the air inside the curved hole 205, which will push the extrusion plug 403 inside the movable hole 207, thereby controlling the movement of the extension bar 4. At the same time, when the piston block 501 compresses the spring 6 in the movable hole 209, when the control bolt is reset and rotated, the piston block 501 will suck in the curved hole 205 to reset and move the extension bar 4. After the spring 6 pushes the piston block 501, the piston block 501 will always have a tendency to move in the movable hole 209, thereby reducing the self-rotation of the screw 5 in the screw hole 208 and ensuring the stability of the screw 5's rotation.
