Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically a thread frame device for a embroidery machine. Background Technology

[0002] Embroidery machine, embroidery machine, or embroidery machinery. When embroidery first began to move away from hand embroidery, what were called embroidery machines at that time were not embroidery machines in the true sense. This is because the embroidery machines at that time were traditional sewing machines with a base plate with small round holes. The sewing machine needle moved up and down constantly, and the hand held the cloth stretched taut with an embroidery frame and moved back and forth. In reality, this so-called embroidery machine was still a form of hand embroidery.

[0003] Chinese utility model patent CN222908275U discloses a thread holder device for a embroidery machine. The device includes a base plate with multiple equidistantly distributed placement rods fixedly mounted on its top. Three circumferentially distributed slide rails are welded to the outer wall of each placement rod. The slide rails have slidably connected limiting parts for restricting the movement of the thread spool. A rotating part is provided at the top of each placement rod to change the distance between the three limiting parts. This utility model, through the three circumferentially distributed limiting parts, can restrict and intercept the inner wall of the thread spool, preventing it from detaching upwards during rotation. This ensures the stability of the thread spool during use, effectively guaranteeing the normal operation of embroidery and ensuring the quality of subsequent embroidery. The rotating part allows for changing the distance between the three limiting parts to accommodate thread spools of different sizes, enhancing the product's practicality.

[0004] The existing thread holder device for embroidery machines has many problems. When the thread bundle gets stuck, the fixing structure between the thread spool and the thread holder cannot withstand the sudden increase in tension, which can easily cause the thread spool to separate from the thread holder. This not only interrupts the embroidery operation, but may also damage the thread bundle and embroidery machine parts. Therefore, there is a problem that the thread spool and the thread holder are easy to separate, and it is not convenient to limit the upper end of the thread spool.

[0005] Therefore, this utility model provides a thread holder device for a embroidery machine to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a thread holder device for a embroidery machine, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire frame device for a embroidery machine, comprising a base plate, a limiting mechanism fixedly connected to the upper surface of the base plate, a wire guide mechanism fixedly connected to the outer surface of the limiting mechanism, the limiting mechanism including a fixed frame fixedly connected to the upper surface of the base plate, a sliding plate slidably connected to the inner wall of the fixed frame, a connecting plate hinged to the outer surface of the sliding plate, a limiting frame hinged to the other end of the connecting plate, a rubber roller rotatably connected to the inner wall of the limiting frame, and a limiting guide rail formed on the upper surface of the fixed frame, with a limiting guide rail slidably connected to the outer surface of the limiting guide rail. The plate has a first bolt threadedly connected to its outer surface. The wire guide mechanism includes a mounting block fixedly connected to the upper surface of the fixed frame. A wire guide bolt is threadedly connected to the outer surface of the mounting block. A second sliding rod is fixedly connected to the upper surface of the wire guide bolt. A first limiting sleeve is slidably connected to the outer surface of the second sliding rod. A rotating limiting sleeve is fixedly connected to the outer surface of the first limiting sleeve. A second limiting sleeve is rotatably connected to the outer surface of the rotating limiting sleeve. A first sliding rod is slidably connected to the outer surface of the second limiting sleeve. A limiting ring is fixedly connected to one end of the first sliding rod. A sponge sleeve is fixedly connected to the inner wall of the limiting ring.

[0008] Furthermore, an oil reservoir is fixedly connected to the outer surface of the first sliding rod, and a cotton thread bundle is fixedly connected to the inner wall of the oil reservoir. The other end of the cotton thread bundle is fixedly connected to the inner wall of the limiting ring.

[0009] By adopting the above technical solution, the cotton wire harness can easily draw the lubricating oil from the inner wall of the oil tank to the sponge sleeve inside the limiting ring, thereby facilitating the lubrication of the wire harness and preventing the wire harness from getting stuck.

[0010] Furthermore, the outer surface of the first limiting sleeve is threaded with a second bolt, and the other end of the second bolt is in contact with the outer surface of the second sliding rod.

[0011] By adopting the above technical solution, the first limiting sleeve can be limited by rotating the second bolt, thereby facilitating the adjustment of the output height of the wire harness.

[0012] Furthermore, a fourth bolt is threadedly connected to the outer surface of the rotating limiting sleeve, and the other end of the fourth bolt is in contact with the outer surface of the second limiting sleeve. A third bolt is threadedly connected to the outer surface of the second limiting sleeve, and the other end of the third bolt is in contact with the outer surface of the first sliding rod.

[0013] By adopting the above technical solution, the outer surface of the fourth bolt is attached to the outer surface of the second limiting sleeve, which facilitates the limiting of the second limiting sleeve and the adjustment of the rotation angle of the second limiting sleeve and the first sliding rod. The first sliding rod is limited by rotating the third bolt.

[0014] Furthermore, a bidirectional threaded rod is rotatably connected to the inner wall of the fixed frame, and a knob is fixedly connected to the upper end of the bidirectional threaded rod through the upper surface of the fixed frame. The outer surface of the bidirectional threaded rod is threadedly connected to the outer surface of the slide plate.

[0015] Using the above technical solution, the two-way threaded rod can be easily rotated by turning the knob, so that the two sets of slides can move in opposite directions.

[0016] Furthermore, the outer surface of the limiting frame is hinged with two sets of connecting plates, and the outer surface of the connecting plates is slidably connected to the outer surface of the fixed frame.

[0017] By adopting the above technical solution, the connecting plate can be easily limited by the through holes on the outer surface of the fixed frame, thereby facilitating the adjustment of the position of the limiting frame.

[0018] Beneficial effects

[0019] This utility model provides a thread holder device for a embroidery machine. Compared with the prior art, it has the following advantages:

[0020] 1. This convenient thread frame device for embroidery machines uses a knob to drive a bidirectional threaded rod, which in turn pushes a sliding plate against a limiting frame. This allows a rubber roller to fit against the side of the thread spool, limiting its movement. At the same time, a sliding limiting plate limits the top of the thread spool and is fixed by a first bolt to prevent the spool from moving upwards. When pulling the thread, the rubber roller can both constrain lateral displacement and buffer and guide, ensuring the stability of the thread spool from multiple directions and preventing it from separating from the fixed frame, thus ensuring a stable supply of thread.

[0021] 2. This convenient thread holder device for embroidery machines, through the cooperation of components such as the second sliding rod and the first limiting sleeve, forms a three-dimensional guiding system. Rotating the second bolt adjusts the height of the first limiting sleeve, precisely controlling the vertical output position of the thread bundle. The fourth and third bolts respectively fix the second limiting sleeve and the first sliding rod, enabling horizontal angle and position adjustments. Regardless of the type of embroidery work being performed, the thread bundle output position can be quickly adjusted to the optimal level, ensuring precise and efficient embroidery.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 5This application provides a wire frame device for a embroidery machine, including a base plate 1. A limiting mechanism 2 is fixedly connected to the upper surface of the base plate 1. A wire guide mechanism 3 is fixedly connected to the outer surface of the limiting mechanism 2. The wire guide mechanism 3 includes a mounting block 302 fixedly connected to the upper surface of a fixed frame 207. A wire guide bolt 301 is threadedly connected to the outer surface of the mounting block 302. A second sliding rod 310 is fixedly connected to the upper surface of the wire guide bolt 301.

A sponge sleeve is fixedly connected to the inner wall of the limiting ring 305.

[0032] Furthermore, an oil reservoir 304 is fixedly connected to the outer surface of the first sliding rod 308, and a cotton thread bundle is fixedly connected to the inner wall of the oil reservoir 304. The other end of the cotton thread bundle is fixedly connected to the inner wall of the limiting ring 305. A second bolt 306 is threadedly connected to the outer surface of the first limiting sleeve 303. The other end of the second bolt 306 is in contact with the outer surface of the second sliding rod 310. A fourth bolt 312 is threadedly connected to the outer surface of the rotating limiting sleeve 311.

A third bolt 309 is fixedly threadedly connected to the outer surface of the second limiting sleeve 307. The other end of the third bolt 309 is in contact with the outer surface of the first sliding rod 308.

[0033] In this embodiment, rotating the knob 210 drives the bidirectional threaded rod 209, causing the slide plate 208 to push the limiting frame 202, so that the rubber roller 201 fits against the side of the spool, limiting the shaking. At the same time, the sliding limiting plate 204 limits the upper part of the spool and is fixed by the first bolt 205 to prevent the spool from moving upward. When pulling the wire, the rubber roller 201 can both constrain the lateral displacement and buffer and guide, ensuring the stability of the spool from multiple directions, preventing it from separating from the fixed frame 207, and ensuring a stable supply of wire harness.

[0034] Reference Figures 1 to 5 In one aspect of this embodiment, the limiting mechanism 2 includes a fixed frame 207 fixedly connected to the upper surface of the base plate 1. A slide plate 208 is slidably connected to the inner wall of the fixed frame 207. A connecting plate 203 is hinged to the outer surface of the slide plate 208. A limiting frame 202 is hinged to the other end of the connecting plate 203. A rubber roller 201 is rotatably connected to the inner wall of the limiting frame 202. A limiting guide rail 206 is provided on the upper surface of the fixed frame 207. A limiting plate 204 is slidably connected to the outer surface of the limiting guide rail 206. A first bolt 205 is threadedly connected to the outer surface of the limiting plate 204.

[0035] Furthermore, a bidirectional threaded rod 209 is rotatably connected to the inner wall of the fixed frame 207. The upper end of the bidirectional threaded rod 209 passes through the upper surface of the fixed frame 207 and is fixedly connected to a knob 210. The outer surface of the bidirectional threaded rod 209 is threadedly connected to the outer surface of the slide plate 208. Two sets of connecting plates 203 are hinged to the outer surface of the limiting frame 202. The outer surface of the connecting plates 203 is slidably connected to the outer surface of the fixed frame 207.

[0036] In this embodiment, a three-dimensional guiding system is formed by the cooperation of components such as the second sliding rod 310 and the first limiting sleeve 303. Rotating the second bolt 306 adjusts the height of the first limiting sleeve 303, precisely controlling the vertical output position of the thread bundle. The fourth bolt 312 and the third bolt 309 respectively fix the second limiting sleeve 307 and the first sliding rod 308, realizing the adjustment of the horizontal angle and position. Regardless of the type of embroidery operation performed by the embroidery machine, the thread bundle output position can be quickly adjusted to the optimal position, ensuring accurate and efficient embroidery.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Working principle: When the thread frame device of the embroidery machine is running, the thread spool is sleeved on the outer surface of the fixed frame 207 and is securely installed using the limiting mechanism 2. Rotating the knob 210 causes the bidirectional threaded rod 209 to rotate, driving the slide plate 208 to slide on the inner wall of the fixed frame 207. The connecting plate 203 pushes the limiting frame 202 to adjust its position, so that multiple sets of rubber rollers 201 fit against the inner wall of the thread spool. Then, the limiting plate 204 is slid so that one end of the limiting plate 204 can limit the top of the thread spool. Then, rotating the first bolt 205 facilitates the limiting of the limiting plate 204. The thread end passes through the limiting ring 305, and the thread mechanism is activated. Rotating the second bolt 306 can adjust the first limiting sleeve 303 on the second sliding rod 310. The position of the bolt 309 precisely controls the output height of the wire harness. Rotating the fourth bolt 312 changes the relative angle between the second limit sleeve 307 and the rotation limit sleeve 311. Rotating the third bolt 309 fixes the first sliding rod 308. The two work together to adjust the output direction of the wire harness. At the same time, the cotton wire harness in the oil tank 304 draws lubricating oil to the sponge sleeve on the inner wall of the limit ring 305. When the wire harness passes through, the sponge sleeve provides lubrication, reduces friction, prevents the wire harness from getting stuck, and ensures a stable and orderly supply of wire harness when the embroidery machine is working. When the embroidery machine starts to pull the thread, the spool rotates smoothly on the outer surface of the rubber roller 201 under tension. The rubber roller 201, with its flexible rotation characteristics, buffers and guides the rotation of the spool, ensuring a smooth pulling process.
