Description

Technical Field

[0001] This invention relates to the technical field of sizing machines, and more particularly to a sizing machine with an automatic yarn changing function. Background Technology

[0002] In the weaving preparation process of the textile industry, the sizing machine is a key piece of equipment used to sizing warp yarns. Its main function is to uniformly coat the yarn surface with sizing solution and then dry it to enhance yarn strength, improve abrasion resistance, and reduce fuzziness, thereby meeting the process requirements of subsequent high-speed weaving. Existing sizing machines typically use a yarn winding bearing to carry the yarn to be sized. The yarn is unwound from the winding beam, passes through the inside of the sizing machine, and is finally wound onto another winding beam to complete the sizing process.

[0003] However, in actual production, after a roll of yarn is sized, the machine must be stopped and the power supply disconnected to ensure operational safety. Then, the operator removes the yarn roll from the equipment's support structure and installs a new yarn roll onto the corresponding positioning slot or support. Afterward, the starting end of each yarn must be pulled out one by one and guided through the sizing machine by workers. Finally, the yarn end is fixed to the target winding shaft by winding before the machine can be restarted. This process not only consumes a lot of manpower, but the portion of yarn bound to the target winding shaft cannot be sized, resulting in yarn waste. Furthermore, the long downtime significantly reduces overall production efficiency, making it difficult to meet the urgent needs of modern textile production for continuous, automated, and high-efficiency processes. Summary of the Invention

[0004] In view of this, the present invention provides a sizing machine with an automatic yarn changing function, which can overcome the disadvantages of the prior art, such as cumbersome manual yarn changing operation, high manpower consumption, long equipment downtime and low production efficiency.

[0005] The technical solution of the present invention is: a sizing machine with an automatic yarn-changing function, comprising: a sizing machine body; a controller installed on the side of the sizing machine body; a fixed frame symmetrically connected to both sides of the sizing machine body; a support rod connected to the fixed frame; a fixing ring connected to the side of the fixed frame, and the fixing ring having a notch; a rotating disk rotatably connected to the fixing ring, and the rotating disk having symmetrically opened placement slots; a first motor installed on the side of the fixed frame, and the output shaft of the first motor connected to the rotating disk; a clamp for clamping the end of the yarn; a fixing component disposed on the yarn winding shaft for fixing the clamp to the yarn winding shaft; a detection component disposed on the fixed frame for detecting the state of the yarn; and a rotation component disposed on the fixed frame for driving the yarn winding shaft to rotate.

[0006] Furthermore, the clamp includes: a fixed clamping plate; a sliding clamping plate slidably connected to the fixed clamping plate; and elastic blocks evenly spaced and connected to the sliding clamping plate, with slots evenly spaced on the fixed clamping plate, and the elastic blocks being engaged in the slots.

[0007] Furthermore, the fixing assembly includes: an iron plate connected to the yarn winding shaft; a rotating rod symmetrically rotatably connected to the fixing clamp; a first magnet connected to the rotating rod; a connecting spring with its two ends connected to the first magnet and the fixing clamp respectively; and a separation mechanism disposed on the fixing clamp for separating the two mutually attracted first magnets.

[0008] Furthermore, the separation mechanism includes: a sliding block, which is symmetrically slidably connected to the fixed clamping plate and is in contact with the first magnet; and a return spring, which is connected to the sliding block and the fixed clamping plate at both ends respectively.

[0009] Furthermore, the detection components include: a distance sensor mounted on the side of one of the fixtures; a laser sensor mounted on the side of the other fixture; and a prompting mechanism mounted on the fixture to prompt the worker to proceed with the next operation.

[0010] Furthermore, the prompting mechanism includes: a first buzzer mounted on the top of one of the mounting brackets; and a second buzzer mounted on the top of the other mounting bracket.

[0011] Furthermore, the rotating assembly includes: a second motor mounted on a fixed frame; and a rubber wheel connected to the output shaft of the second motor, with the rubber wheel in contact with the yarn winding shaft.

[0012] Furthermore, it also includes: a fixed clamping rod, symmetrically connected to the side of the fixed clamping plate; a rotating clamping rod, symmetrically rotatably connected to the sliding clamping plate, and the rotating clamping rod and the fixed clamping rod are engaged with each other; and a second magnet, symmetrically connected to the sliding clamping plate, and the second magnet attracts the rotating clamping rod by magnetic force.

[0013] The beneficial effects are: 1. By cooperating with a fixed ring, a rotating disk and a first motor, the present invention can automatically switch the spare yarn roll to the working position when a roll of yarn is used up. At the same time, the clamps can automatically connect the ends of the new and old yarns, avoiding the cumbersome operation of manually pulling the yarn through the inside of the sizing machine, greatly shortening the equipment downtime and ensuring the continuity and production efficiency of the sizing operation.

[0014] 2. This invention, by setting up a clamping structure including a fixed clamping plate, a sliding clamping plate, and an elastic locking block, combined with the function of the fixing components, enables the yarn end to be firmly clamped and quickly adsorbed onto the yarn winding shaft. During the winding process, the two clamps are connected by adsorption through the first magnet, realizing automatic yarn docking. When separating, the first magnet is rotated and separated by pushing the sliding block. The operation is simple and reliable, effectively avoiding the yarn waste and equipment downtime caused by traditional winding and fixing.

[0015] 3. This invention monitors the remaining yarn amount and clamp position by setting distance sensors and laser sensors respectively. With the prompts of the first and second buzzers, the system can automatically issue prompts when the yarn is used up and the traction is completed, guiding the worker to perform the corresponding operations. At the same time, combined with the rotating assembly consisting of the second motor and the rubber wheel, the automatic rotation control of the yarn winding shaft is realized. The entire winding process is automated under the coordination of the controller, which not only reduces manual intervention, but also improves the safety of operation and the system response accuracy.

[0029] Example: A sizing machine with automatic yarn changing function, such as Figures 1-9 As shown, the sizing machine includes a sizing machine body 1, a controller 2, a fixing frame 3, a support rod 4, a fixing ring 5, a rotating disk 6, a first motor 7, a clamp, a fixing assembly, a detection assembly, and a rotating assembly. The controller 2 is installed on the front right side of the sizing machine body 1. Fixing frames 3 are symmetrically connected to both the front and rear sides of the sizing machine body 1. There are four fixing frames 3. The upper parts of the two fixing frames 3 on the left are connected to the support rod 4, and the upper parts of the two fixing frames 3 on the right are connected to the support rod 4. Each of the four fixing frames 3 is connected to a fixing ring 5. Each fixed ring 5 has a notch 501 at its lower part. Each fixed ring 5 is rotatably connected to a rotating disk 6. Each rotating disk 6 has two symmetrical placement slots 601. The middle of each of the four fixed frames 3 is equipped with a first motor 7, and the output shaft of the first motor 7 is connected to the rotating disk 6. The clamp is used to clamp the end of the yarn. The yarn winding shaft 001 is provided with a fixing component for fixing the clamp. The fixed frame 3 is provided with a detection component for detecting the yarn condition. The fixed frame 3 is provided with a rotating component for driving the yarn winding shaft 001 to rotate.

[0030] like Figure 4 and Figure 5As shown, the clamp includes a fixed clamping plate 8, a sliding clamping plate 9, and elastic blocks 10. The sliding clamping plate 9 is slidably connected to the fixed clamping plate 8. Multiple elastic blocks 10 are evenly spaced on the sliding clamping plate 9. The fixed clamping plate 8 has evenly spaced slots 11, which correspond one-to-one with the elastic blocks 10, and the elastic blocks 10 are locked in the slots 11.

[0031] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the fixing assembly includes an iron plate 12, a rotating rod 13, a first magnet 14, a connecting spring 15, and a separation mechanism. Each yarn winding shaft 001 is connected to an iron plate 12. Each fixing clamp 8 has symmetrically opened storage slots on its side, and a rotating rod 13 is rotatably connected in each storage slot. Each rotating rod 13 is connected to a first magnet 14. A connecting spring 15 is connected between the first magnet 14 and the fixing clamp 8. The fixing clamp 8 is provided with a separation mechanism for separating two mutually attracted first magnets 14. The separation mechanism includes a sliding block 16 and a return spring 17. Sliding blocks 16 are slidably connected to both the front and rear sides of each fixing clamp 8. The sliding blocks 16 correspond one-to-one with the first magnets 14, and the sides of the sliding blocks 16 and the first magnets 14 that are close to each other are inclined and in contact with each other. A return spring 17 is connected between the sliding blocks 16 and the fixing clamp 8.

[0032] like Figure 1 As shown, the detection assembly includes a distance sensor 18, a laser sensor 19, and a prompting mechanism. The distance sensor 18 is installed on the upper front side of the right rear bracket 3, and the distance sensor 18 is directly opposite the yarn winding shaft 001 on the upper right side. The laser sensor 19 is installed on the upper front side of the left rear bracket 3, and the laser sensor 19 is located above the support rod 4 on the left side. The bracket 3 is equipped with a prompting mechanism for prompting the worker to perform the next operation. The prompting mechanism includes a first buzzer 20 and a second buzzer 21. The first buzzer 20 is installed on the top of the right front bracket 3, and the second buzzer 21 is installed on the top of the left front bracket 3.

[0033] like Figure 1 As shown, the rotating assembly includes a second motor 22 and a rubber wheel 23. The upper part of each of the four fixed frames 3 is equipped with a second motor 22. The output shaft of the second motor 22 is connected to the rubber wheel 23, and the rubber wheel 23 is in contact with the yarn winding shaft 001.

[0034] Before using the device, a yarn spool 001 containing yarn needs to be prepared. When preparing the yarn, first move the fixed clamp 8 and sliding clamp 9 on the two clamps away from each other, disengaging the elastic block 10 from the slot 11. Then, place the ends of multiple yarns between the fixed clamp 8 and sliding clamp 9 on one of the clamps. Next, move the fixed clamp 8 and sliding clamp 9 closer together to close them, engaging the elastic block 10 into the slot 11, thus fixing the yarn ends on the clamp. Then, place the clamp on the iron plate 12 of the yarn spool 001. The first magnet 14 on the clamp is attracted to the iron plate 12 by magnetic force, connecting the yarn ends to the yarn spool 001. Then, drive the yarn spool 001 to rotate using a winding device to wind the yarn onto the yarn spool 001. After winding the yarn, repeat the above operation and fix the end of the yarn to another clamp. When using this device to sizing the yarn, first place a yarn-loaded spool 001 below the right side of the rotating disk 6, then move the yarn-loaded spool 001 to the left so that both ends of the yarn-loaded spool 001 pass through the notches 501 on the two fixing rings 5 ​​on the right side and enter the placement slots 601 on the lower side of the two rotating disks 6 on the right side. Similarly, an empty yarn-loaded spool 001 can be placed in the placement slots 601 on the lower side of the two rotating disks 6 on the left side. Then, the controller 2 controls the first motor 7 to drive the rotating disk 6 to rotate 180 degrees. The rotating disk 6 can drive the yarn-loaded spool 001 on it to rotate 180 degrees, so that the yarn-loaded spool 001 is located on the upper part of the rotating disk 6. At this time, the fixing rings 5 ​​can limit the yarn-loaded spool 001 in the placement slots 601 (e.g., Figure 3As shown), to prevent the yarn winding shaft 001 from shifting within the placement groove 601; then, the worker passes the clamp at the end of the yarn around the right support rod 4, through the interior of the sizing machine body 1, and then around the left support rod 4, finally placing the clamp at the end of the yarn on the empty yarn winding shaft 001, thus quickly connecting the end of the yarn to the empty yarn winding shaft 001, thereby completing the yarn traction work; then, the controller 2 controls the sizing machine body 1 to start working, and controls the second motor 22 to drive the rubber wheel 23 to rotate, the rubber wheel 23 can drive The yarn winding shaft 001 rotates counterclockwise to unwind the yarn on the right yarn winding shaft 001, while the left yarn winding shaft 001 winds the yarn. The yarn passes through the inside of the sizing machine body 1 to complete the sizing process. During the sizing process, the worker can place the next yarn winding shaft 001 filled with yarn and the next empty yarn winding shaft 001 into the placement slots 601 on the lower side of the left and right rotating disks 6, respectively. At the same time, the distance sensor 18 can monitor the remaining amount of yarn on the yarn winding shaft 001. When the clamp at the beginning of the yarn is pulled away from the yarn winding shaft 001 by the yarn tension... When the yarn is pulled off the iron plate 12 of 01, it means that the yarn on the yarn winding shaft 001 has been used up. At this time, the distance sensor 18 will send a signal. After receiving the signal, the controller 2 will control the sizing machine body 1 and the second motor 22 to stop working, so that the yarn stops moving. At this time, the end of the yarn will hang down on the support rod 4 on the right. At the same time, the controller 2 will control the first motor 7 on the right to drive the rotating disk 6 on the right to rotate 180 degrees, so that the two yarn winding shafts 001 on the rotating disk 6 on the right will switch positions. At the same time, the controller 2 will control the first buzzer 20 to sound. The sound indicates that the worker can pick up the clamp on the end of the yarn on the new yarn winding shaft 001 and bring it close to the clamp on the end of the yarn hanging on the right support rod 4 so that the two clamps are connected together by the first magnet 14, so that the connection of the ends of the two yarn rolls can be completed quickly. Then, the controller 2 controls the second motor 22 on the left to drive the rubber wheel 23 on the left to rotate, which drives the yarn winding shaft 001 on the left to continue to rotate and wind the yarn. In this way, the next yarn roll can be automatically passed through the inside of the sizing machine body 1 by pulling the previous yarn roll.When the laser sensor 19 detects that the two connected clamps have passed above the left support rod 4, it means that the previous roll of yarn has been completely wound. At this time, the laser sensor 19 will send a signal. After receiving the signal, the controller 2 will control the second motor 22 on the left to stop working and control the second buzzer 21 to sound an alarm. At this time, the worker needs to push the sliding block 16 on the two connected clamps towards the first magnet 14. The return spring 17 is compressed, and the sliding block 16 will squeeze the first magnet 14 to rotate. The connecting spring 15 is compressed, causing the first magnet 14 on the two clamps to separate from each other, making it easier for the worker to separate the two connected clamps. At this time, the end of the next roll of yarn will hang down on the left support rod 4. Then, the sliding block is released. 16. The return spring 17 returns to its original state, causing the sliding block 16 to move away from the first magnet 14 and reset. The connecting spring 15 also returns to its original state, causing the first magnet 14 to rotate and reset. Then, the controller 2 controls the first motor 7 on the left to drive the left rotating disk 6 to rotate 180 degrees, which allows the two yarn winding shafts 001 on the left rotating disk 6 to switch positions. Then, the worker places the clamp on the yarn end hanging from the left support rod 4 onto the iron plate 12 of the upper left yarn winding shaft 001, which quickly connects the yarn end to the new yarn winding shaft 001. The above operation is repeated to sizing the next roll of yarn. During the sizing process, the yarn winding shaft 001 in the placement groove 601 on the lower side of the rotating disk 6 can be replaced again.

[0035] like Figure 10 and Figure 11 As shown, it also includes a fixed clamping rod 24, a rotating clamping rod 25, and a second magnet 26. Each fixed clamping plate 8 has a fixed clamping rod 24 symmetrically connected to its side front and back. Each sliding clamping plate 9 has a rotating clamping rod 25 symmetrically connected to its side front and back. The rotating clamping rod 25 corresponds to and engages with the fixed clamping rod 24. Each sliding clamping plate 9 has a second magnet 26 symmetrically connected to its side front and back. The second magnet 26 corresponds to the rotating clamping rod 25.

[0036] In the initial state, the fixed lever 24 and the rotating lever 25 are disengaged (e.g., Figure 9 (As shown) When the worker clamps the end of the yarn onto the fixture, the rotating clamp 25 can be rotated 90 degrees to engage with the fixed clamp 24. The side of the rotating clamp 25 will then contact the second magnet 26. The second magnet 26 can magnetically attract the rotating clamp 25, preventing it from rotating arbitrarily. The engagement of the fixed clamp 24 and the rotating clamp 25 locks the front and rear ends of the sliding clamp 9. During the movement of the yarn, the front and rear ends of the sliding clamp 9 are prevented from lifting upwards due to the compression of the yarn, thus preventing the yarn from coming loose.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
