Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a straight tube integrated yarn cutting machine. Background Technology

[0002] In the textile industry, the straight tube integrated yarn cutting machine is a key piece of equipment for yarn cutting and processing, and its performance directly affects production efficiency and yarn processing quality. Traditional yarn cutting machines face several technical bottlenecks in practical applications: First, the limited design of the bobbin support and conveying structure makes it difficult to stably support bobbins of different sizes, and the inconvenience of adjusting the support roller spacing results in poor equipment versatility. Second, bobbins are prone to shifting or jamming during conveying due to unstable support, especially at high speeds. Third, the bobbins after yarn cutting usually require manual intervention for collection or the use of specialized collection components, leading to low automation and increased labor intensity. Fourth, the collection of cut yarn often requires a separate negative pressure collection system or allows it to fall freely. Setting up a separate negative pressure collection system increases equipment costs, while allowing the yarn to fall freely leads to scattering and contamination of the working environment and material waste. These problems make it difficult for traditional yarn cutting machines to meet the demands of modern textile industry's refined and intelligent production requirements when facing the need for multi-specification yarn processing and efficient automated production.

[0003] Therefore, this utility model proposes a straight tube integrated yarn cutting machine to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0012] A further feature of this invention is that the support roller is configured with a variable diameter.

[0013] By adopting the above technical solution, the bobbin can be automatically dropped between the two support rollers when it continues to be conveyed backward after the yarn is cut on the bobbin.

[0014] The present invention is further configured as follows: the linkage assembly includes four support plates, four rotating shafts, two connecting plates, four linkage gears, eight synchronous pulleys, and four synchronous belts. Support plates are radially rotatably mounted on both the front and rear ends of the two support shafts. Rotating shafts are rotatably mounted on all four support plates. The same connecting plate is rotatably mounted on two rotating shafts located on the same side. Linkage gears are fixedly sleeved on all four rotating shafts. Two linkage gears located on the same side mesh with each other. Synchronous pulleys are fixedly sleeved on both the front and rear ends of the two support shafts and on the four rotating shafts.

[0027] The support guide assembly provides stable support for the two support rollers and facilitates spacing adjustment. This allows it to accommodate spools of different sizes when used with the pressure guide assembly. The drive and linkage components work together to control the two support rollers to rotate synchronously in opposite directions. The spiral rubber strips on the support rollers ensure stable spool conveying even when they rotate synchronously in opposite directions. The arc-shaped concave guide rollers used in the pressure guide assembly further enhance the stability of the spool during conveying, ensuring that it does not deviate or jam at high speeds.

[0028] The system, featuring an electric cylinder, lifting plate, circular box, and airflow spray gun, can cut yarn on a bobbin passing below the spray gun. Due to the variable diameter of the support roller, the yarn detaches automatically from the support roller as it continues to be conveyed, effectively reducing manual intervention and improving efficiency. Furthermore, the system, with its connecting hose, guide box, housing, and strip-shaped inlet, efficiently collects the cut yarn, avoiding the yarn scattering and drifting problems that can occur with traditional methods. The regulating valve allows operators to flexibly adjust the airflow according to actual needs, thus optimizing the processing effect for yarns of different materials. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] Reference Figure 1-6 A straight tube integrated yarn cutting machine includes a mounting frame 1, a support frame 2, a lifting plate 21, an electric cylinder 211, a circular box 22, two support rollers 3, two support shafts 31 and two spiral rubber strips 301;

[0039] The support frame 2 is fixedly installed on the top side of the mounting frame 1. The lifting plate 21 is slidably installed on the support frame 2. The electric cylinder 211 is fixedly installed on the support frame 2, and the telescopic end of the electric cylinder 211 is fixedly installed on the top side of the lifting plate 21. The circular box 22 is fixedly installed on the bottom side of the lifting plate 21, and an air inlet pipe 221 is fixedly installed on the circular box 22. An airflow spray gun 23 is fixedly installed at the bottom of the circular box 22. Two guide ports are opened on the mounting frame 1.

[0040] Guide bars 321 are fixedly installed in both guide openings, and guide blocks 32 are slidably installed in both guide openings. The guide bars 321 and the two guide blocks 32 located in the same guide opening are slidably connected. Two support shafts 31 are arranged parallel to each other and rotatably installed on the corresponding two guide blocks 32. Two support rollers 3 are fixedly installed on the corresponding support shafts 31, which can provide stable support for the support rollers 3. Two bidirectional screws 322 are rotatably installed in both guide openings. The two bidirectional screws 322 are threadedly connected to the corresponding two guide blocks 32. Two servo motors 323 are fixedly installed on one side of the support frame 2. The output shafts of the two servo motors 323 are axially fixedly connected to the corresponding bidirectional screws 322, which can adjust the distance between the two support rollers 3 as needed.

[0041] Two spiral rubber strips 301 are fixedly installed on the outer side of the corresponding support rollers 3, and the threads of the two spiral rubber strips 301 are opposite, so that the conveying operation of the bobbin can be realized when the two support rollers 3 keep rotating synchronously in opposite directions. Support plates 33 are radially rotatably installed at the front and rear ends of the two support shafts 31. Rotating shafts 34 are rotatably installed on the four support plates 33. The same connecting plate 341 is rotatably installed on the two rotating shafts 34 on the same side. Linkage gears 342 are fixedly sleeved on the four rotating shafts 34. The two linkage gears 342 on the same side mesh with each other. Synchronous pulleys 35 are fixedly sleeved at the front and rear ends of the two support shafts 31 and on the four rotating shafts 34. The same synchronous belt 351 is connected to the two synchronous pulleys 35 close to the same support plate 33, so that the two support shafts 31 keep rotating synchronously in opposite directions, and are not affected by the change in the distance between the two support rollers 3.

[0042] A drive motor 36 is fixedly installed on the bottom side of one of the connecting plates 341. A drive gear 361 is fixedly sleeved on the output shaft of the drive motor 36. The drive gear 361 meshes with one of the linkage gears 342 and can provide driving force for the two support shafts 31.

[0043] Multiple rotating rods arranged in parallel to each other are rotatably mounted on the mounting frame 1. Guide rollers 4 are fixedly mounted on each of the multiple rotating rods. The outer circumferential surface of the guide rollers 4 is set with an arc-shaped concave surface, which can press and limit the bobbins conveyed on the two support rollers 3. At the same time, it can increase the contact area between the guide rollers 4 and the bobbins, thereby ensuring that they can be stably conveyed to the cutting position.

[0044] Specifically, in order to allow the bobbin to fall off between the two support rollers 3 on its own when it continues to be conveyed after the yarn is cut on the bobbin, the support rollers 3 are designed with a variable diameter.

[0045] Specifically, in order to utilize airflow to convey and collect the yarn cut from the bobbin downwards through the guide box 24, and to ensure that the airflow delivered to the guide box 24 through the connecting hose 242 flows downwards, thereby effectively improving the yarn collection effect, the guide box 24 is fixedly installed on the mounting frame 1. A housing 241 is fixedly installed on both sides of the guide box 24. Multiple strip-shaped openings communicating with the two housings 241 are provided on both sides of the housings 241. Connecting hoses 242 are fixedly installed on both housings 241, and both connecting hoses 242 are connected to the circular box 22. The strip-shaped openings are inclined towards the bottom of the guide box 24.

[0046] Specifically, in order to adjust the air flow rate delivered to the feed box 24 as needed, a regulating valve is installed on the connecting hose 242.

[0047] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0048] Working principle:

[0049] First, turn on the power. Place the spool of yarn to be cut on the two support rollers 3 along the axial direction of the support shaft 31. Then, start the drive motor 36. The drive motor 36 drives the linkage gear 342 to rotate through the drive gear 361. The rotation of the linkage gear 342 is transmitted to the two support shafts 31 through the synchronous pulley 35 and the synchronous belt 351, so that the two support shafts 31 rotate synchronously in opposite directions. Since the spiral rubber strip 301 is fixedly installed on the outside of the support roller 3 and the threads of the two spiral rubber strips 301 are opposite, the spiral rubber strip 301 can push the spool forward smoothly while the support shaft 31 rotates. The servo motor 323 can adjust the position between the two guide blocks 32 in the same guide port by controlling the rotation of the bidirectional lead screw 322, thereby changing the distance between the two support rollers 3 to accommodate spools of different sizes.

[0050] At the same time, the electric cylinder 211 adjusts the height of the lifting plate 21 as needed, so that the circular box 22 and the air spray gun 23 are aligned with the yarn cutting position on the bobbin. The air spray gun 23 uses high-pressure gas entering from the air inlet pipe 221 to precisely cut the yarn. After the cutting is completed, because the support roller 3 adopts a variable diameter design, the bobbin will gradually lose its support force as it continues to be conveyed backward, and eventually automatically fall from between the two support rollers 3, reducing manual intervention.

[0051] The cut yarn is drawn into the guide box 24 by the airflow blown out through the connecting hose 242 under the action of airflow. During this process, the inclined strip opening on the housing 241 can guide the airflow downward, ensuring that the yarn can be efficiently collected into the guide box 24. At the same time, the operator can flexibly control the airflow in the connecting hose 242 according to actual needs by adjusting the valve to optimize the collection effect of yarns of different materials. Throughout the process, the arc-shaped concave guide roller 4 always maintains a stable limit on the yarn drum, avoiding deviation or jamming during high-speed conveying, thereby ensuring the efficient operation and safety of the equipment.

[0052] The present invention provides a detailed description of a straight-tube integrated yarn cutting machine. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
