[0029] The present invention will be further described in detail below in conjunction with the examples and drawings, but the implementation of the present invention is not limited to this.
[0030] Such as figure 1 As shown, the bobbin holder for an industrial sewing machine in this embodiment includes a bottom plate 1 and a two-dimensional linear module 2. The bottom plate 1 is made of a steel plate, and the steel plate can be made into a groove shape to collect wire ends and other debris generated during the normal operation of the wire reel frame. In order to facilitate the movement of the wire reel, a two-dimensional linear module needs to be introduced. The fixed module of the two-dimensional linear module is fixed on the ground, the motion module of the two-dimensional linear module slides vertically relative to the fixed module of the two-dimensional linear module, and the bottom of the base plate 1 is welded to the bottom of the two-dimensional linear module. On the motion module. Among them, the two-dimensional linear module is a conventional XY linear module, which can realize the fast movement of the wire reel rack, so that the wire reel rack can be adjusted in real time according to the operating status of the industrial sewing machine.
[0031] A threaded hole is opened in the middle of the top of the bottom plate 1, and the threaded hole is screwed with a steel support column 7, which is a straight rod. In order to reduce the weight, the support column 7 can also be arranged in a hollow structure. A retaining ring 5 and a cover plate 4 are provided on the supporting column 7. The retaining ring 5 is arranged on the supporting column 7 close to the outer circumferential wall above the yarn bobbin holder 8. The retaining ring 5 is sleeved on the supporting column 7, specifically, the retaining ring 5 It is in the shape of a truncated cone, and the cross section of the stop ring 5 is a circular structure. This arrangement saves material and can effectively resist the friction of the yarn drum holder 8. The retaining ring 5 and the support column 7 are welded or screwed together. In addition, the cover plate 4 is made of plastic material, the support column 7 penetrates the cover plate 4, and the cover plate 4 and the support column 7 are hinged. The bottom of the cover plate 4 is provided with a card slot 15 which matches the yarn bobbin holder 8; specifically, such as image 3 As shown, the outer walls on both sides of the bottom of the cover plate 4 are provided with four clamping grooves 15, and the inner walls of the bottoms of the four clamping grooves 15 are all attached to the top of the yarn drum holder 8, which can effectively perform Limiting, thereby preventing the problem of yarn loose edge caused by the tilt of the yarn tube, and improving the quality of yarn conduction. It should be noted that the retaining ring 5 is located below the cover plate 4 to avoid the accumulation of dust or debris on the retaining ring 5.
[0032] Further, such as figure 2 As shown, the top outer walls of the cover plate 4 close to the two sides of the support column 7 are provided with threading holes 16 to improve the efficiency of yarn conduction. In addition, a wire reel 6 is sleeved on the outer wall of the support column 7 close to the threading hole 16, and the top outer wall of the wire reel 6 is provided with a groove 11, which promotes the fixation of the wire loop 14 and improves the stability of the wire. Further, such as figure 2 As shown, the top outer wall of the groove 11 is clamped with a wire loop 14, and the top outer wall of the wire loop 14 is provided with four wire holes 12, and the yarn of the yarn tube can quickly and effectively pass through the wire loop 14 and the wire hole 12. Thus, the occupied area of the wire space of the traditional wire mechanism is reduced, and the wire work is more stable and quicker. In addition, such as figure 2 As shown, the center of the bottom of the groove 11 is provided with a jack 13, and four LED lights 10 are arranged on the outer side of the wire reel 6 near the top of the wire loop 14, which facilitates the staff to distinguish and distinguish different colors and types of yarns. distinguish.
[0033] Both sides of the top of the bottom plate 1 are respectively provided with fixing holes, and a yarn drum holder 8 is arranged in the fixing holes. Generally, the bottom of the yarn drum holder 8 is threadedly connected with the threads in the fixing holes. The fixing holes on one side of the bottom plate 1 can be set to two, and the fixing holes on the other side of the bottom plate 1 are also set to two. The inner walls of the four fixing holes are all fixed with a yarn drum holder 8 through threads. The four yarn drum holders 8 The outer wall of the circumference is sleeved with a sleeve 3, and the arrangement of the sleeve 3 can prevent the yarn bobbin holder 8 from being damaged by collision.
[0034] Such as Figure 4 As shown, one end of the bottom plate 1 is provided with a fixed block 18, and the fixed block 18 is fixed on the bottom plate 1 through a fixed snap ring 9. Both the fixed block 18 and the fixed snap ring 9 are made of metal materials. Such as Figure 4 As shown, both sides of the fixed block 18 are provided with circular grooves 19, and the circular grooves 19 can be arranged in a fingerprint structure, which facilitates the replacement of the fixed snap ring 9 by the staff and improves the practicability of the overall device. A rubber gasket 17 is arranged on the inner side of the fixed snap ring 9 to facilitate the enhancement of the friction between the fixed snap ring 9 and the bottom plate 1 and improve the installation and disassembly efficiency of the bottom plate 1.
[0035] The bottom plate 1 is also provided with an elastic backing plate, and the elastic backing plate abuts against the outer circumference of the yarn tube support 8 to avoid damages caused by touching the bottom plate 1 when the yarn tube support 8 vibrates. Specifically, the sponge pad 2 is selected as the elastic pad. The sponge pad 2 is adhered to the outer circumferential wall of the bottom plate 1 close to the bottom end of the yarn tube holder 8, which increases the friction at the bottom of the yarn tube and effectively ensures the yarn The efficiency of the tube wire.
[0036] In order to reduce the relative sliding between the fixed snap ring 9 and the bottom plate 1, the inner ring wall of the rubber gasket 17 contacting the bottom plate 1 is provided with anti-slip protrusions. Specifically, the anti-slip protrusions are triangular or point-shaped protrusions.
[0037] The working principle of the above-mentioned spool holder for industrial sewing machines is: when in use, the bottom plate 1 is fixed to the fixing frame by the fixing snap ring 9, and then the yarn drum is placed on the yarn drum holder 8 and the cover 4 Covering the top of the yarn tube holder 8 can effectively limit the top of the yarn tube holder 8 to prevent the problem of yarn loose edges caused by the tilt of the yarn tube, improve the quality of yarn conduction, and make the yarn tube support The top end of 8 abuts the inner wall of the slot 15, while the wire reel 6 is sleeved on the outer circumferential wall of the support column 7 and placed above the cover plate 4. At the same time, the wire loop 14 is covered on the groove 11 on the top of the wire reel 6 Inside, the fixing of the wire loop 14 is promoted, and the stability of the wire is improved. One end of the yarn wound on each yarn tube is passed through the threading hole 16 of the cover plate 4, and is respectively led out through the wire hole 12 of the wire loop 14 , Thereby reducing the occupied area of the wire space of the traditional wire mechanism, making the wire work more stable and quicker, and an LED lamp 10 is arranged on the top of the wire reel 6 to distinguish and distinguish yarns of different colors and types.
[0038] The above-mentioned embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations, etc. made without departing from the spirit and principle of the present invention Simplified, all should be equivalent replacement methods, and they are all included in the protection scope of the present invention.
