Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a quick-change mechanism for textile machinery. Background Technology

[0002] Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., were originally hand-operated looms in ancient times. The term "textile machine" is a general term for the tools used to process raw materials such as thread, silk, and hemp into yarn and then weave them into cloth. Modern mechanical looms and modern CNC automatic looms are also mentioned.

[0003] Currently, when textile machinery uses yarn for placement, the yarn needs to be changed during the textile process due to the different colors of different products. The current method for changing yarn in textile machines is manual. After disassembling the yarn spools used on the textile machine, the yarn spools to be used are then installed on the textile machine. These steps need to be completed manually step by step, which is a cumbersome process that reduces the efficiency of yarn changing and reduces production efficiency. Summary of the Invention

[0029] This specific embodiment is a quick-change thread mechanism for textile machinery, such as... Figures 1-8 As shown, the system includes a textile machine 1. A bobbin holder 2 is fixedly installed on one side of the top of the operating table of the textile machine 1. The top of the bobbin holder 2 has an installation groove 201, and a bobbin 3 is installed in the installation groove 201. A positioning rod 202 is vertically fixedly connected to the center of the bottom end of the installation groove 201. A bobbin base 301 is fixedly connected to the bottom of the bobbin 3. A through hole is provided on the bobbin 3 and the bobbin base 301 for the positioning rod 202 to pass through. A fixing component for fixing the bobbin base 301 is provided on the bobbin holder 2. A yarn changing mechanism 4 is installed on one side of the bobbin holder 2 on the top of the operating table of the textile machine 1. The yarn changing mechanism 4 includes a rotating plate 401. The rotating plate 401 has a circumferentially oriented... Four spool mounting holes 4011 are equally spaced, and the spools 3 are installed and fixed in the holes 4011. A linkage clamping component 405 is provided on the rotating plate 401 at each spool mounting hole 4011. The linkage clamping component 405 is used to clamp / release the spools 3. A movable seat 402 is rotatably connected to the center of the rotating plate 401. Two support rods 404 are movably connected to the movable seat 402. The support rods 404 are vertically arranged and slidably connected to the movable seat 402. The bottom end of the support rod 404 is fixedly connected to the operating table of the textile machine 1. The top ends of the two support rods 404 are connected to a connecting plate 4041. A reset component 406 is provided on one side of the connecting plate 4041.

[0030] Specifically, the bobbin holder 2 is used to install the bobbins 3 required by the textile machine 1. The remaining spare bobbins 3 are installed in the bobbin mounting holes 4011 of the rotating plate 401. When changing yarn, the rotating plate 401 is rotated to rotate the empty bobbin mounting holes 4011 on the rotating plate 401 to the bobbin holder 2. The operator slides and presses down the rotating plate 401 on the support rod 404, so that the bobbins 3 in the bobbin holder 2 automatically detach from the bobbin holder 2 and are installed in the bobbin mounting holes 4011 at the current position. This is used to automatically separate the bobbins 3 on the bobbin holder 2. Then, by releasing the rotating plate 401, the rotating plate 401 is reset under the action of the reset component 406. Then, the rotating plate 401 is rotated again to select the bobbin 3 to be used and place it in the bobbin holder 2. The rotating plate 401 is pressed down again to make the selected bobbin 3 detach from the rotating plate 401 and automatically install it on the bobbin holder 2. The operation is simple and greatly improves the efficiency of yarn changing and production efficiency.

[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the fixing component includes a fixing block 206. Both sides of the mounting groove 201 are provided with first accessory grooves 203 within the spool fixing base 2. One end of the first accessory groove 203 is connected to the mounting groove 201. The fixing block 206 is slidably installed inside the first accessory groove 203, with its clamping end extending into the mounting groove 201. A first spring 209 is fixedly installed between the side of the fixing block 206 away from the mounting groove 201 and the inner wall of the first accessory groove 203. A first engaging groove 302 is annularly formed on the outer wall of the spool base 301 for the fixing block 206 to engage. When the spool 3 is installed on the spool fixing base 2, the spool base 301 is placed within the mounting groove 201. Under the action of the first spring 209, the fixing block 206 is pushed into the mounting groove 201, causing the fixing block 206 to engage in the first engaging groove 302 of the spool base 301, thereby installing the spool 3 onto the spool fixing base 2.

[0032] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the fixing assembly also includes a connecting rod 207 and a trapezoidal block 208. A third accessory slot 205 is provided between the two first accessory slots 203 on the spool fixing base 2. The trapezoidal block 208 is slidably installed inside the third accessory slot 205. The width of the trapezoidal block 208 gradually decreases from top to bottom. A second accessory slot 204 is provided between the first accessory slot 203 and the third accessory slot 205. A connecting rod 207 is slidably installed in the second accessory slot 204. One end of the connecting rod 207 is fixedly connected to the fixing block 206. The other end of the connecting rod 207 extends into the third accessory slot 205 and is movably hinged to a roller. The roller abuts against the inclined surface on the side of the trapezoidal block 208. A second spring 210 is fixedly installed between the bottom of the trapezoidal block 208 and the bottom of the inner part of the third accessory slot 205.

[0033] Furthermore, the top of the trapezoidal block 208 is fixedly connected to a fixing rod 211 that passes through the third accessory slot 205.

[0034] Specifically, during the line changing operation, as the rotating plate 401 is pressed down, it contacts the fixed rod 211, pressing the fixed rod 211 into the third accessory slot 205. The fixed rod 211 drives the trapezoidal block 208 to move downwards synchronously, causing the connecting rod 207 to slide on the inclined surface of the trapezoidal block 208 via rollers. This causes the two connecting rods 207 to move synchronously in a direction away from each other, causing the connecting rods 207 to drive the fixed block 206 to move into the first accessory slot 203, releasing the fixing effect on the spool base 301. This facilitates the automatic separation of the spool 3 from the spool fixing seat 2. The second spring 210 is used to quickly reset the positions of the trapezoidal block 208 and the fixed rod 211 for the next operation.

[0035] In this embodiment, as Figure 7 As shown, the bottom of the movable seat 402 is fixedly connected to a base plate 403 below the rotating plate 401. The bottom of the rotating plate 401 has four ball positioning grooves 4012 along the circumferential direction. The top of the base plate 403 has two symmetrical grooves 4031. Balls 4032 are movably installed inside the grooves 4031. The ball 4032 protrudes from the grooves 4031 and is engaged in the ball positioning grooves 4012. A third spring 4033 is installed between the ball 4032 and the bottom of the groove 4031. When the rotating plate 401 rotates, the third spring 4033 pushes the ball 4032 into the ball positioning grooves 4012. The four ball positioning grooves 4012 correspond one-to-one with the four spool mounting holes 4011. This is used to position the rotating plate 401 when it rotates to the correct position, ensuring that the spool mounting holes 4011 are aligned and moved to the spool fixing seat 2, thus ensuring the accuracy of the wire changing.

[0036] In this embodiment, as Figure 6 and Figure 8As shown, the linkage clamping assembly 405 includes a positioning plate 4051, a U-shaped plate 4052, a first steel wire rope 4053, and a limiting block 4054. Two positioning plates 4051 are respectively positioned on both sides of the spool mounting hole 4011. The bottom end of the positioning plate 4051 is fixedly connected to the rotating plate 401. The top ends of the two positioning plates 4051 are slidably connected between them. Receiving grooves 4013 are provided on both sides of the spool mounting hole 4011 on the rotating plate 401. The limiting block 4054... The first steel wire rope 4053 is vertically provided on the positioning plate 4051, which is slidably installed in the receiving groove 4013. One end of the through hole 40511 is connected to the receiving groove 4013. The first steel wire rope 4053 is placed in the through hole 40511, and one end is fixedly connected to the U-shaped plate 4052. The other end is fixedly connected to the limiting block 4054. A fourth spring 4055 is sleeved between the limiting block 4054 and the inner wall of the receiving groove 4013 and outside the first steel wire rope 4053.

[0037] Furthermore, a second locking groove 303 is provided in a ring on the outer wall of the spool base 301 for the locking block 4054 to be inserted. The second locking groove 303 is located above the first locking groove 302. The width of the second locking groove 303 is more than twice the width of the locking block 4054. When the spool base 301 is installed on the spool fixing seat 2, the second locking groove 303 is placed outside the spool fixing seat 2.

[0038] Specifically, the base 301 of the spool 3 is placed into the spool mounting hole 4011. The fourth spring 4055 pushes the limiting block 4054 to move into the spool mounting hole 4011, and the limiting block 4054 is engaged in the second locking groove 303, thereby installing the spool 3 into the spool mounting hole 4011.

[0039] When the spool 3 on the spool fixing seat 2 is installed into the empty spool mounting hole 4011, the rotating plate 401 is pressed down and pressed against the top of the spool fixing seat 2. At this time, the spool 3 automatically separates from the spool fixing seat 2, and the positioning rod 202 abuts against the U-shaped plate 4052. Pushing the U-shaped plate 4052 upward causes the first wire rope 4053 to move, which in turn pulls the limiting block 4054 to move. Move the plate 401 into the receiving groove 4013, and then reset the rotating plate 401 so that the U-shaped plate 4052 separates from the positioning rod 202. Under the elastic action of the fourth spring 4055, push the limiting block 4054 into the spool mounting hole 4011, thereby locking the limiting block 4054 into the second locking groove 303, and installing the spool 3 into the empty spool mounting hole 4011, so as to separate and remove the spool 3 from the spool fixing seat 2.

[0040] When installing other spools 3, rotate the selected spool 3 to the spool fixing seat 2, and press down and move the rotating plate 401 again so that the positioning rod 202 abuts against the U-shaped plate 4052. The first wire rope 4053 pulls the limiting block 4054 to move into the receiving groove 4013, releasing the fixing effect on the spool base 301, separating the spool 3 from the rotating plate 401, and the spool 3 falls into the mounting groove 201 under the action of gravity and is fixed, realizing the quick line changing operation of the spool 3.

[0041] In this embodiment, as Figure 6 As shown, the reset assembly 406 includes a support plate 4061, a fixed plate 4062, a movable plate 4063, a second steel wire rope 4064, and a guide wheel 4066. The support plate 4061 is horizontally arranged and one end is fixedly connected to the connecting plate 4041. The fixed plate 4062 is fixedly connected to the top of the support plate 4061 near the connecting plate 4041. The movable plate 4063 is slidably connected to the top of the support plate 4061 away from the connecting plate 4041. The movable plate 4063 moves along... The support plate 4061 slides along its length. A notch is provided on the connecting plate 4041, and a guide wheel 4066 is rotatably connected inside the notch. One end of the second steel wire rope 4064 is fixedly connected to the moving plate 4063, and the other end of the second steel wire rope 4064 passes through the fixed plate 4062 and passes around the guide wheel 4066 to be fixedly connected to the bottom of the moving seat 402. A fifth spring 4065 is sleeved between the fixed plate 4062 and the moving plate 4063 and outside the second steel wire rope 4064.

[0042] Specifically, when the rotating plate 401 moves downward, the second steel wire rope 4064 drives the moving plate 4063 to move closer to the fixed plate 4062, thereby squeezing and contracting the fifth spring 4065. When the operator does not apply force to the rotating plate 401, the fifth spring 4065 pushes the moving plate 4063 and the rotating plate 401 to quickly reset.

[0043] In this embodiment, as Figure 6 As shown, an L-shaped rod 407 is fixedly connected to the outer wall of the base plate 403, and a handle 408 is fixedly connected to the top of the L-shaped rod 407. The operator can easily press down and move the rotating plate 401 by holding the handle 408.

[0044] Working principle: When changing yarn on textile machine 1, the operator rotates the rotating plate 401, moving the empty bobbin mounting hole 4011 on the rotating plate 401 to the bobbin fixing seat 2. The operator then slides the rotating plate 401 down on the support rod 404 by holding the handle 408. When the rotating plate 401 contacts the fixing rod 211, the fixing rod 211 is pressed into the third accessory slot 205. The fixing rod 211 drives the trapezoidal block 208 to move downwards synchronously, causing the connecting rod 207 to slide on the inclined surface of the trapezoidal block 208 via rollers. This causes the two connecting rods 207 to move synchronously in a direction away from each other, thus... The connecting rod 207 drives the fixing block 206 to move into the first accessory slot 203, releasing the fixing effect on the spool base 301. Simultaneously, the positioning rod 202 abuts against the U-shaped plate 4052, pushing the U-shaped plate 4052 upwards. The U-shaped plate 4052 drives the first steel wire rope 4053 to move, causing the first steel wire rope 4053 to pull the limiting block 4054 into the receiving slot 4013. Then, the rotating plate 401 is reset, causing the U-shaped plate 4052 to separate from the positioning rod 202. Under the elastic action of the fourth spring 4055, the limiting block 4054 is pushed into the spool mounting hole 4011, thereby... The limiting block 4054 is inserted into the second receiving groove 303, and the spool 3 is installed into the empty spool mounting hole 4011 to separate the spool 3 from the spool fixing seat 2. The operator releases the rotating plate 401, and the rotating plate 401 is reset by the action of the reset component 406. Then, the rotating plate 401 is rotated to rotate the spool 3 to be used to the spool fixing seat 2. The rotating plate 401 is pressed down again, so that the positioning rod 202 abuts against the U-shaped plate 4052. The limiting block 4054 is moved into the receiving groove 4013 by the first wire rope 4053, releasing the spool base. The fixing function of 301 separates the spool 3 from the rotating plate 401. Under the action of gravity, the spool 3 falls into the mounting groove 201 and is fixed. The rotating plate 401 is reset by the action of the reset component 406. The second spring 210 is used to quickly reset the position of the trapezoidal block 208 and the fixing rod 211. Under the action of the first spring 209, the fixing block 206 is pushed into the mounting groove 201, so that the fixing block 206 is engaged in the first engaging groove 302 of the spool base 301, thereby installing the spool 3 onto the spool fixing seat 2. The present invention is simple to operate and greatly improves the efficiency of changing the spool and the production efficiency.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
