Technical Field

[0001] This utility model relates to the field of biodegradable fiber production technology, specifically to an automatic thread feeding mechanism for biodegradable fiber production. Background Technology

[0002] Biodegradable fiber thread is a fiber material made from natural polymers (such as starch and cellulose) or synthetic biodegradable polymers (such as polylactic acid and polybutylene adipate) through a spinning process. It possesses biodegradable properties, gradually decomposing into harmless substances in the natural environment or under specific conditions (such as bodily fluids), and retains a certain strength and flexibility, allowing it to be manufactured in different thicknesses as needed. This type of raw material is the foundational material for producing biodegradable sutures, packaging ropes, medical dressings, and other products. Its structural characteristics must be adapted to subsequent processing techniques (such as weaving and coating) while simultaneously meeting the degradation performance and strength requirements of the final product. The automatic thread feeding mechanism in biodegradable fiber thread production is a device on the production line used for automatically conveying the raw fiber thread. It typically consists of a pay-off spool, tension adjustment components, and a thread feeding drive roller. The pay-off spool is used to hold the fiber thread roll.

[0003] In existing automated thread feeding mechanisms for biodegradable fiber production, the tension adjustment components are not easy to move with the movement of the fiber thread during unwinding, resulting in the fiber thread being subjected to large traction and easily breaking. Therefore, an automated thread feeding mechanism for biodegradable fiber production is needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic wire feeding mechanism for biodegradable fiber production, including a base 1. Two vertical plates 101, two vertical plates 102, and two vertical plates 103 are fixedly connected to the top of the base 1. A wire feeding assembly 2 is provided between the side ends of the two vertical plates 101. A translation assembly 3 is provided between the side ends of the two vertical plates 102. A pressing assembly 4 is provided at the top of the translation assembly 3. A winding assembly 5 is provided between the side ends of the two vertical plates 103. When the wire is fed through the wire feeding assembly 2, the translation assembly 3... As the fiber line moves horizontally, the pressure assembly 4 tensions the fiber line, and the winding assembly 5 can simultaneously wind up the unloaded fiber line. At this time, the unload roller 202 unloads the fiber line while the moving plate 306 moves horizontally, and the winding roller 502 winds it up simultaneously, thereby realizing automatic feeding of the fiber line during the production process. This allows the entire pressure assembly 4 to move along with the fiber line as it is unwound, preventing the fiber line from being pulled too much and breaking. It also facilitates the winding of the fiber line by each winding roller 502 in batches, making it convenient for subsequent storage or sale.

[0021] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the wire feeding assembly 2 includes a rotating rod 201, which is rotatably disposed between the side ends of two vertical plates 101. A wire feeding roller 202 is fixedly installed on the outer end of the rotating rod 201. A sprocket 203 is fixedly connected to the side end of the rotating rod 201. The outer end of the wire feeding roller 202 is provided with a material feed absorbing wire. The translation assembly 3 includes a motor 301, which is fixedly installed on the side end of the right vertical plate 102. A reciprocating screw 302 is installed at the output end of the motor 301. The side end of the reciprocating screw 302 is rotatably disposed on the side end of the left vertical plate 102. A sprocket 303 and a sprocket 304 are fixedly connected to the outer end of the reciprocating screw 302. 304, sprockets 2 and 304 are spaced apart, a chain 6 is sleeved between the outer ends of sprockets 1 and 203, a guide rod 305 is fixedly connected between the side ends of the two vertical plates 2 102, a movable plate 306 is threadedly connected to the outer end of the reciprocating screw 302, the bottom side end of the movable plate 306 is sleeved on the outer end of the guide rod 305, the winding assembly 5 includes a rotating rod 2 501, the rotating rod 2 501 is rotatably disposed between the side ends of the two vertical plates 3 103, a winding roller 502 is fixedly connected to the outer end of the rotating rod 2 501, and a sprocket 4 503 is fixedly connected to the side end of the rotating rod 2 501, sprockets 3 and 304 are also fixedly connected. Chain 2 7 is sleeved between the outer ends of the two sprockets. In practice, the reciprocating screw 302 is rotated by starting the motor 301. At this time, the guide rod 305 limits the movement of the moving plate 306. At the same time, the rotation of the reciprocating screw 302 drives the sprocket 2 303 and sprocket 3 304 to rotate. Since chain 1 6 is sleeved between the outer ends of sprocket 1 203 and sprocket 2 303, and chain 2 7 is sleeved between the outer ends of sprocket 3 304 and sprocket 4 503, the pay-off roller 202 and the take-up roller 502 will also rotate. At this time, the pay-off roller pays off the fiber thread, and the fiber thread will move horizontally from left to right or from right to left during the rotation of the pay-off roller 202. The moving plate 306 can move horizontally along with the fiber line as it is unwound. The pressing component 4 presses and tensions the fiber line. At this time, the take-up roller 502 rotates continuously, taking the fiber line that is being unwound back and forth from left to right or from right to left. At this time, the unwound roller 202 unwound the fiber line while the moving plate 306 moves horizontally, and the take-up roller 502 takes it up at the same time. This realizes the automatic feeding of the fiber line in the production process, so that the pressing component 4 can move along with the fiber line as it is unwound, avoiding the fiber line from being pulled too much and breaking. This makes it easy for each take-up roller 502 to take up the fiber line in batches, which is convenient for subsequent storage or sale.

[0022] As one implementation method in this embodiment, such as Figure 2As shown, the pressing component 4 includes a limiting frame 401, which is fixedly connected to the top of the movable plate 306. A rod 402 is inserted into the top of the limiting frame 401, and an annular plate 403 is fixedly connected to the bottom of the rod 402. A limiting rod 405 is fixedly connected to the top of the annular plate 403. The limiting rod 405 is inserted into the top of the limiting frame 401, and a limiting plate 406 is fixedly connected to the top of the limiting rod 405. A spring 404 is sleeved on the outer end of the rod 402, with the top of the spring 404 fixedly connected to the top of the limiting frame 401 and the bottom of the spring 404 fixedly connected to the annular plate 403. At the top, during implementation, the fiber thread will be laid out horizontally from left to right or from right to left as the pay-off roller 202 rotates. Therefore, the moving plate 306 can be laid out horizontally along with the fiber thread. At this time, the annular plate 403 limits the fiber thread, and the annular plate 403 presses down on the fiber thread through the spring 404 to achieve tension. At this time, the take-up roller 502 rotates continuously and takes up the fiber thread that is laid out horizontally from left to right or from right to left. At this time, the pay-off roller 202 lays out the fiber thread while the moving plate 306 moves horizontally and the take-up roller 502 takes up the fiber thread while the pay-off roller 202 lays out the fiber thread, thereby realizing automatic feeding of the fiber thread in the production process.

[0023] Working principle: The motor 301 drives the reciprocating screw 302 to rotate. Due to the limiting action of the guide rod 305, the moving plate 306 can be moved horizontally. Simultaneously, the rotation of the reciprocating screw 302 drives the second sprocket 303 and the third sprocket 304 to rotate. Since chain 6 is fitted between the outer ends of the first sprocket 203 and the second sprocket 303, and chain 7 is fitted between the outer ends of the third sprocket 304 and the fourth sprocket 503, the unwinding roller 202 and the take-up roller 502 also rotate. The unwinding roller unwinds the fiber thread, and as the unwinding roller 202 rotates, the fiber thread will be moved horizontally from left to right or from right to left. Therefore, the moving plate 306 can move along with the fiber thread. As the fiber moves horizontally together, the annular plate 403 limits the fiber. The annular plate 403 presses down on the fiber through the spring 404 to achieve tension. At this time, the take-up roller 502 rotates continuously, taking the fiber that is being unwound from left to right or from right to left. At this time, the unwinding roller 202 unwinds the fiber while the moving plate 306 moves horizontally, and the take-up roller 502 takes it up at the same time. This realizes the automatic feeding of the fiber in the production process, so that the entire pressing component 4 can move with the fiber as it is unwound, avoiding the fiber from being pulled too much and breaking. This makes it easy for each take-up roller 502 to take up the fiber in batches, which is convenient for subsequent storage or sale.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
