A quick-change bobbin device for textile machinery

Abstract

This utility model discloses a quick-change bobbin device for textile machinery, belonging to the field of textile machinery technology. It includes a base, with an adjustment mechanism rotatably connected to the inner wall of the base, and an installation mechanism fixedly connected to the outer surface of the adjustment mechanism. This quick-change bobbin device requires the bobbin bodies to be stacked in a uniform direction within an L-shaped plate. The stepped groove of the support base and the central limiting post precisely fix the bobbin case opening upwards. During replacement, the bottom bobbin falls into the bobbin case only in a fixed direction under gravity, physically restricting the bobbin's installation direction. Simultaneously, the linkage design of the push plate and the limiting plate ensures that only one bobbin conforming to the required direction is released each time, avoiding the problem of reverse installation due to misidentification of direction during manual bobbin removal. This eliminates the need for operators to additionally check the direction, significantly reducing the probability of reverse installation.

Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a quick-change bobbin device for textile machinery. Background Technology

[0002] Textile machinery is the core equipment for textile production, encompassing multiple categories such as spinning machines, looms, and sewing machines. During operation, looms and sewing machines rely on the bobbin to continuously supply thread to complete the weaving and sewing processes of fabrics. As the core component that carries the thread, the bobbin is typically a cylindrical sleeve with thread wrapped around its outer surface. In use, it needs to be embedded inside the bobbin case, and then the entire bobbin case is installed into the shuttle box of the textile machinery. The mechanical operation drives the bobbin to rotate, achieving a stable output of thread.

[0003] Because the thread output paths of different models of textile machinery are different, the corresponding bobbin installation direction requirements are also different. Moreover, the direction markings on the bobbin itself have obvious defects. Most bobbins only have tiny arrow markings printed on the end face, and operators need to observe them repeatedly at close range to identify the direction. Some low-cost bobbins do not even have any direction markings. Therefore, there is a problem of low bobbin installation efficiency.

[0004] Therefore, this utility model provides a quick-change bobbin device specifically for textile machinery to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-change bobbin device specifically for textile machinery, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change bobbin device for textile machinery, comprising a base, an adjustment mechanism rotatably connected to the inner wall of the base, and an installation mechanism fixedly connected to the outer surface of the adjustment mechanism. The adjustment mechanism includes a bidirectional bolt rod rotatably connected to the inner wall of the base, and a connecting block threadedly connected to the outer surface of the bidirectional bolt rod. Two sets of connecting blocks are provided, and a first moving plate and a second moving plate are respectively fixedly connected to the upper surface of the connecting blocks. An L-shaped plate is fixedly connected to the outer surface of both the first and second moving plates. The installation mechanism includes a fixed cylinder fixedly connected to the outer surface of the L-shaped plate. A limit post is slidably connected to the inner wall of the fixed cylinder. One end of the limit post passes through the side surface of the L-shaped plate, and the other end of the limit post passes through the outer surface of the fixed cylinder and is fixedly connected to a pull ring.

[0007] Furthermore, a push plate is slidably connected to the outer surface of the first movable plate, and a first spring is fixedly connected to the outer surface of the push plate, with the other end of the first spring fixedly connected to the outer surface of the first movable plate.

[0008] By adopting the above technical solution, the sliding connection between the push plate and the first moving plate ensures that the push plate moves only in a fixed direction, avoiding the failure of the subsequent limiting plate due to the displacement of the push plate; the elastic reset function of the first spring can automatically drive the push plate back to the initial position after the operator releases the push plate.

[0009] Furthermore, a limiting plate is fixedly connected to the side surface of the push plate, the upper surface of the limiting plate is slidably connected to the lower surface of the L-shaped plate, and multiple sets of bobbin bodies are slidably connected to the outer surface of the L-shaped plate.

[0010] By adopting the above technical solution, the limiting plate and the push plate are directly fixed, and the linear movement of the push plate can realize the rapid separation or bonding of the limiting plate and the L-shaped plate.

[0011] Furthermore, a second spring is fixedly connected to the inner wall of the fixed cylinder, and the other end of the second spring is fixedly connected to the outer surface of the limiting post, and the fixed cylinder is disposed above the limiting plate.

[0012] By adopting the above technical solution, the second spring provides a continuous elastic preload to the limiting post, so that the limiting post always remains in contact with the side surface of the bobbin body. Even when the device vibrates slightly, it can stably limit the position of the bobbin and prevent multiple bobs from falling off at the same time.

[0013] Furthermore, a support base is fixedly connected to the upper surface of the base, and a stepped groove is formed on the upper surface of the support base.

[0014] By adopting the above technical solution, the shape of the stepped groove is precisely matched with the shape of the shuttle body, which can realize the rapid positioning of the shuttle and ensure that the opening of the shuttle is always facing upward, so as to catch the dropped shuttle core.

[0015] Furthermore, the inner side of the stepped groove is fitted with the shuttle body, and a limit post is fixedly connected to the center of the support base.

[0016] By adopting the above technical solution, the support base provides an independent placement platform for the shuttle body, avoiding wear caused by the shuttle body directly contacting the base.

[0017] Furthermore, the two ends of the connecting block are fixedly connected to knobs through the outer surface of the base, and the knobs are rotatably connected to the side surface of the base.

[0018] Using the above technical solution, the knob is located on the outside of the base and protrudes from the base surface, allowing the operator to directly grasp and rotate it by hand without the need for tools such as wrenches.

[0019] Beneficial effects This invention provides a quick-change bobbin device specifically for textile machinery. Compared with the prior art, it has the following advantages: 1. This quick bobbin changing device for textile machinery requires the bobbin bodies to be stacked in a uniform direction within an L-shaped plate. The stepped groove of the support base and the central limiting post can precisely fix the bobbin case opening to the upward position. During replacement, the bottom bobbin can only fall into the bobbin case in a fixed direction under the action of gravity, which restricts the installation direction of the bobbin from a physical structure. At the same time, the linkage design of the push plate and the limiting plate ensures that only one bobbin that meets the direction requirements is released at a time, avoiding the problem of reverse installation caused by misidentification of direction when manually removing bobs. There is no need for operators to check the direction, which greatly reduces the probability of reverse installation.

[0020] 2. This quick-change bobbin device for textile machinery, through the cooperation of a bidirectional bolt rod, two sets of connecting blocks and L-shaped plates, allows the operator to drive the bidirectional bolt rod to rotate by turning the knob on the outside of the base. The reverse thread drives the connecting blocks and the first and second moving plates to move synchronously in opposite directions, thereby adjusting the distance between the two sets of L-shaped plates. This structure can flexibly adapt to bobbin bodies of different lengths and specifications, ensuring that bobbins of different specifications can be placed stably, avoiding limit failure or unstable storage problems caused by mismatched bobbin specifications.

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

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 5 This application provides a quick-change bobbin device for textile machinery, including a base 1. An adjustment mechanism 2 is rotatably connected to the inner wall of the base 1, and an installation mechanism 3 is fixedly connected to the outer surface of the adjustment mechanism 2. The adjustment mechanism 2 includes a bidirectional bolt rod 207 rotatably connected to the inner wall of the base 1. A connecting block 205 is threadedly connected to the outer surface of the bidirectional bolt rod 207. Two sets of connecting blocks 205 are provided, and a first moving plate 203 and a second moving plate 204 are fixedly connected to the upper surface of the connecting blocks 205 respectively. An L-shaped plate 202 is fixedly connected to the outer surface of both the first moving plate 203 and the second moving plate 204. The installation mechanism 3 includes a fixing cylinder 301 fixedly connected to the outer surface of the L-shaped plate 202. A limit post 308 is slidably connected to the inner wall of the fixing cylinder 301. One end of the limit post 308 passes through the side surface of the L-shaped plate 202, and the other end of the limit post 308 passes through the outer surface of the fixing cylinder 301 and is fixedly connected to a pull ring 302.

[0027] Furthermore, a push plate 310 is slidably connected to the outer surface of the first moving plate 203, a first spring 303 is fixedly connected to the outer surface of the push plate 310, the other end of the first spring 303 is fixedly connected to the outer surface of the first moving plate 203, a limit plate 304 is fixedly connected to the side surface of the push plate 310, the upper surface of the limit plate 304 is slidably connected to the lower surface of the L-shaped plate 202, and multiple sets of bobbin bodies 307 are slidably connected to the outer surface of the L-shaped plate 202. A second spring 309 is fixedly connected to the inner wall of the fixed cylinder 301, the other end of the second spring 309 is fixedly connected to the outer surface of the limit post 308, and the fixed cylinder 301 is located above the limit plate 304.

[0028] In this embodiment, the bobbin bodies 307 need to be stacked in the L-shaped plate 202 in a uniform direction, and the stepped groove 206 of the support base 305 and the central limiting post 308 can accurately fix the bobbin case opening to the upward position. When replacing, the bottom bobbin can only fall into the bobbin case in a fixed direction under the action of gravity, which restricts the installation direction of the bobbin from a physical structure perspective. At the same time, the linkage design of the push plate 310 and the limiting plate 304 ensures that only one bobbin that meets the direction requirements is released each time, avoiding the problem of reverse installation caused by the error of direction identification when manually picking the bobbin. There is no need for the operator to check the direction, which greatly reduces the probability of reverse installation.

[0029] Reference Figures 1 to 5 In one aspect of this embodiment, a support base 305 is fixedly connected to the upper surface of the base 1. A stepped groove 206 is provided on the upper surface of the support base 305. The inner side of the stepped groove 206 is attached to the shuttle body 306, and a limit post 308 is fixedly connected to the center of the support base 305.

[0030] Furthermore, the two ends of the connecting block 205 are fixedly connected to the knob 201 through the outer surface of the base 1, and the knob 201 is rotatably connected to the side surface of the base 1.

[0031] In this embodiment, through the cooperation of the bidirectional bolt rod 207, two sets of connecting blocks 205 and L-shaped plate 202, the operator can drive the bidirectional bolt rod 207 to rotate by turning the knob 201 on the outside of the base 1. The reverse thread drives the connecting block 205 and the first moving plate 203 and the second moving plate 204 to move in opposite directions synchronously, thereby adjusting the distance between the two sets of L-shaped plates 202. This structure can flexibly adapt to bobbin bodies 307 of different lengths and specifications, ensuring that bobsbins of different specifications can be placed stably, avoiding limit failure or unstable storage problems caused by mismatched bobbin specifications.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: First, the operator holds the knob 201 on the side surface of the base 1 and rotates it. The knob 201 drives the bidirectional bolt rod 207, which is fixedly connected to it, to rotate synchronously on the inner wall of the base 1. Since the threads of the two sets of connecting blocks 205 on the outer surface of the bidirectional bolt rod 207 are opposite, when the bolt rod rotates, it drives the two sets of connecting blocks 205 to move in opposite directions along the bolt rod axis. This, in turn, drives the first moving plate 203 and the second moving plate 204 on the upper surface of the connecting block 205 to move synchronously, ultimately achieving the adjustment of the distance between the two sets of L-shaped plates 202 until the distance is completely matched with the length of the bobbin body 307, at which point the knob 201 is stopped from being rotated. Then, the operator manually pulls the pull ring 302 in the installation mechanism 3. The pull ring 302 drives the limiting post 308 to slide outward of the fixed cylinder 301. At this time, the second spring 309 inside the fixed cylinder 301 is compressed. The bobbin body 307 with the wound wire bundle is stacked in the same direction between the two sets of L-shaped plates 202. After stacking, the pull ring 302 is released, and the second spring 309 elastically resets and pushes the limiting post 308 to move towards the L-shaped plate 202 until the limiting post 308 passes through the side surface of the L-shaped plate 202 and fits against the side of the outermost bobbin body 307. This provides lateral limiting for multiple sets of bobbins and prevents the bobbins from sliding at will. At the same time, the push plate 310 on the outer surface of the first moving plate 203 is in the initial position under the support of the first spring 303. The limiting plate 304 on the side of the push plate 310 fits against the lower surface of the L-shaped plate 202 and provides bottom support for the stacked bobbins, completing the preparation work before replacement.

[0034] When the bobbin of a textile machine needs to be replaced, firstly, the bobbin case body 306 is removed from the machine, and the used bobbin is taken out. Then, the empty bobbin case body 306 is placed into the stepped groove 206 of the support base 305. The inner wall of the stepped groove 206 and the limiting post 308 in the center of the support base 305 work together to keep the bobbin case stable and with the opening facing upward. Next, the operator pushes the push plate 310 towards the first moving plate 203. The push plate 310 slides along the surface of the first moving plate 203 and squeezes the first spring 303, causing the first spring 303 to contract. At the same time, the push plate 310 drives the side limiting plate 304 to slide away from the L-shaped plate 202. When the limiting plate 304 is completely disengaged... When the L-shaped plate 202 is lowered, the bottommost bobbin body 307 inside the L-shaped plate 202 loses support and falls vertically under its own weight, accurately landing in the inner wall of the lower bobbin case body 306. During this process, the limiting post 308 in the fixing cylinder 301, under the continuous preload of the second spring 309, remains in contact with the side surface of the remaining upper bobbin body 307, effectively preventing the upper bobbin from falling with the bottom bobbin. After the bottom bobbin is successfully installed in the bobbin case, the operator releases the push plate 310. The first spring 303 elastically resets, causing the push plate 310 to return to its initial position. Simultaneously, the push plate 310 causes the limiting plate 304 to re-adhere to the lower surface of the L-shaped plate 202, continuing to support the remaining bobbin. Finally, the operator removes the bobbin case body 306 with the new bobbin from the stepped groove 206 of the support base 305 and installs it back into the designated position on the textile machinery, thus completing a complete bobbin replacement process.
