Description

Technical Field

[0001] This invention relates to the field of needle punching machine technology, and specifically to a polyester-cotton yarn needle punching machine. Background Technology

[0002] Polyester-cotton yarn is a yarn made from a blend of polyester and cotton. It is characterized by its high breaking strength and is often used to make polyester-cotton canvas or blankets. The manufacturing process requires the assistance of a needle punching machine.

[0003] Existing needle punching machines use needles to hook loose polyester-cotton yarn, forming it into a blanket shape. The blanket-shaped fabric is then wound up by a take-up roller. However, insufficient tension is a common problem during the winding process. Insufficient tension can lead to inadequate support for the inner core of the blanket-shaped fabric, causing it to collapse during subsequent handling. In existing technologies, if insufficient tension occurs, the machine needs to be stopped for adjustment, which affects the processing efficiency of the device.

[0004] Therefore, this invention proposes a polyester-cotton yarn needle punching machine to improve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a polyester-cotton yarn needle punching machine to solve the problems mentioned above in the background art.

The tensioning element includes a hinge frame hinged to the support platform, a tension roller for bearing the fabric is mounted on the hinge frame, an auxiliary frame for supporting the hinge frame is hinged to the support platform, a pull rod is hinged to the auxiliary frame, a pull spring is mounted on the support platform, and a drive rod hinged to the pull rod is mounted on the free end of the pull spring. The clamping plate is mounted on the hinge frame, and a gap is formed between the clamping plate and the tension roller for the fabric to pass through.

[0007] Furthermore, a scraping roller is rotatably mounted on the clamping plate, the clamping plate is slidably connected to the hinge frame, a rotating wheel is mounted at the end of one of the support rollers, a drive disk is rotatably mounted on the bearing platform, the drive disk and the rotating wheel are connected by a pulley assembly, a movable rod is hinged on the drive disk, and the free end of the movable rod is hinged to the clamping plate.

[0008] Furthermore, two curved rollers are rotatably mounted on the support platform. The curved rollers are connected to each other through a main gear set. A drive wheel is installed at the end of the support roller that is not equipped with a rotating wheel. A rotating rod is rotatably mounted on the support platform. The drive wheel and the rotating rod are connected through a pulley assembly. The rotating rod and the shaft of one of the curved rollers are connected through a bevel gear set.

[0009] Furthermore, multiple ring plates are installed on the support platform, the number of ring plates being the same as the number of support rollers. The projection of the ring plates is located at the connection between the support rollers and the support platform, and the height of the ring plates is higher than the height of the highest point of the support rollers. A sponge block is installed inside the ring plate, and the ring plates contact the support rollers through the sponge block.

[0010] Furthermore, a uniform plate is slidably mounted on the support platform, the uniform plate is connected to the ring plate, and an abutment plate for contacting the curved roller is mounted on the uniform plate. A return spring is installed between the abutment plate and the support platform.

[0011] Furthermore, an mounting plate is installed on the clamping plate, and a scraper plate is installed on the mounting plate. The end of the scraper plate contacts the scraper roller.

[0014] Furthermore, an ear plate is installed on the support platform, an insertion rod is installed on the drive rod, an insertion hole is opened on the ear plate to slide with the insertion rod, and a pull spring is sleeved on the outside of the insertion rod.

[0015] Furthermore, a cavity is provided on the tension roller so that the weight of the tension roller is less than the pulling force exerted by the pull spring on the pull rod.

[0016] The beneficial effects of this invention are as follows: In use, this invention uses a take-up roller to wind up the fabric. During this process, a support roller supports the fabric being transported, reducing the possibility of excessive fabric sagging. The fabric between the take-up roller and the support roller is supported by a tension roller. When the fabric is being transported, the tension decreases, and a pull spring pulls a pull rod via a drive rod. This pull rod then pulls an auxiliary frame, which in turn pushes a hinge frame. The hinge frame then drives the tension roller to contact the fabric being transported, reducing the gap between the fabric and the device, increasing the fabric tension, and improving the processing efficiency of the device.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-10As shown, in one embodiment of the present invention, a polyester-cotton yarn needle punching machine includes a needle punching machine body 1, on one side of which a take-up roller 101 is provided. The needle punching machine body 1 is prior art, consisting of a needle punching execution unit and a fiber web processing structure, etc. In use, polyester-cotton yarn is placed into the device, and needle punching causes the polyester-cotton yarn to form an initial cohesive structure. Then, multiple punctures are used to increase the density and form the fabric. The take-up roller 101 is used to take up the blanket-like fabric after needle punching. The machine also includes: The support platform 2 has multiple support rollers 201 rotatably mounted on it. The support rollers 201 are used to support the fabric. The support platform 2 is located between the needle punching machine body 1 and the winding roller 101. The support rollers 201 are driven by a motor. One of the support rollers 201 is directly connected to the motor as a power roller. The other support rollers 201 are connected to the power roller through a transmission chain or belt. Its working principle is the same as that of the existing roller conveyor. When the fabric is formed, the support platform 2 is located between the two to support the fabric. The rotation of the support rollers 201 makes the fabric more stable to be wound by the winding roller 101. This reduces the possibility of the fabric drooping too much during transportation, which may cause damage or reduced tension. This increases the practicality of the device. The end of the support platform 2 closest to the needle punching machine body 1 is set as the discharge end, and the end of the support platform 2 closest to the winding roller 101 is set as the unloading end. Tensioner 3 is installed on support platform 2. Tensioner 3 includes hinge frame 301 hinged to support platform 2. Tension roller 302 for supporting fabric is installed on hinge frame 301. Hinge frame 301 is located between support platform 2 and take-up roller 101. In normal state, tension roller 302 has a similar function to support roller 201 to support fabric and reduce the possibility of sagging. An auxiliary frame 303 for supporting the hinged frame 301 is hinged to the support platform 2. A pull rod 304 is hinged to the auxiliary frame 303. A pull spring 305 is installed on the support platform 2. A drive rod 306 hinged to the pull rod 304 is installed on the free end of the pull spring 305. The pull spring 305 forces the drive rod 306 away from the unloading end. The hinge point between the pull rod 304 and the auxiliary frame 303 does not coincide with the hinge point between the auxiliary frame 303 and the support platform 2. This allows the drive rod 306 to pull the pull rod 306 when the pull spring 305 pulls it, and in turn, the pull rod 304 pulls the auxiliary frame 303, causing the auxiliary frame 303 to rotate away from the unloading end. When the device is in normal condition, the fabric is transported and is in a taut state. Therefore, the fabric will press the tension roller 302, and then press the auxiliary frame 303 through the hinge frame 301, which will cause the pull spring 305 to be in a stretched state. When the device is in use, if the tension decreases due to the gap between the fabric and the device during transportation, a gap will also appear between the fabric and the tension roller 302. At this time, the fabric cannot press the tension roller 302, so the force applied by the fabric to the tension roller 302 is released, the pull spring 305 is reset, the drive rod 306 pulls the pull rod 304, and then the pull rod 304 pulls the auxiliary frame 303 to rotate. At this time, the free end of the auxiliary frame 303 pushes against the hinge frame 301, forcing the tension roller 302 to contact the fabric again. By contacting, the fabric is forced to tighten again, increasing the tension of the fabric and increasing the practicality of the device. The clamping plate 4 is installed on the hinge frame 301. A gap is formed between the clamping plate 4 and the tension roller 302 for the fabric to pass through. The clamping plate 4 is installed on the hinge frame 301 so that when the fabric passes through the hinge frame 301, the tension roller 302 and the clamping plate 4 limit the fabric, making the fabric more stable during transportation. Compared with existing technologies, in use, the fabric is wound up by the take-up roller 101, and the fabric is supported by the support roller 201 during the process, reducing the possibility of excessive fabric sagging. The fabric between the take-up roller 101 and the support roller 201 is supported by the tension roller 302. When the fabric is transported, the tension decreases, and the pull spring 305 pulls the pull rod 304 through the drive rod 306, causing the pull rod 304 to pull the auxiliary frame 303. In turn, the auxiliary frame 303 pushes the hinge frame 301, causing the hinge frame 301 to drive the tension roller 302 to resist the fabric being transported. This reduces the gap between the fabric and the device, increases the tension of the fabric, and improves the processing effect of the device.

[0021] like Figure 4 As shown, a portion of the structure on the clamping plate 4 is disclosed. In some embodiments, a scraping roller 401 is rotatably mounted on the clamping plate 4. The clamping plate 4 is slidably connected to the hinge frame 301. The scraping roller 401 is used to contact the fabric surface. When the fabric contacts the scraping roller 401, the friction between the two drives the scraping roller 401 to rotate. The scraping roller 401 scrapes away the rough edges and dust on the fabric, and can also smooth the fabric, thus improving the processing effect of the device. One of the support rollers 201 has a rotating wheel 402 mounted at its end. A drive disc 403 is rotatably mounted on the support platform 2. The drive disc 403 and the rotating wheel 402 are connected by a pulley assembly. A movable rod 404 is hinged to the drive disc 403, and the free end of the movable rod 404 is hinged to the clamping plate 4. The pulley assembly includes two pulleys and a belt. One pulley is connected to the drive disc 403, and the other pulley is connected to the rotating wheel 402. The belt is used to drive the two pulleys, so that when the support roller 201 rotates, it drives the rotating wheel 402 to rotate. When wheel 402 rotates, it also drives drive disc 403 to rotate. Movable rod 404 is eccentrically hinged to drive disc 403. When drive disc 403 rotates, it drives movable rod 404 to make circular motion around the axis of drive disc 403. In turn, movable rod 404 pushes and pulls clamping plate 4, causing clamping plate 4 to slide back and forth on hinge frame 301. This further increases the relative sliding between scraper roller 401 and fabric, further increases the smoothing effect and cleaning effect of scraper roller 401 on fabric, and increases the practicality of the device.

[0022] like Figure 1 and Figure 6 As shown, a portion of the structure on the support platform 2 is disclosed. In some embodiments, two curved rollers 5 are rotatably mounted on the support platform 2. The curved rollers 5 are connected to each other via a main gear set 503. The curved rollers 5 are rotatably connected to the support platform 2 via a rotating shaft, and the roller body of the curved roller 5 is curved along the axial direction of the rotating shaft, such as... Figure 1 As shown, the main gear set 503 includes two gears, which are respectively connected to the rotating shafts of the two curved rollers 5, so that when one of the curved rollers 5 rotates, it can drive the other curved roller 5 to rotate synchronously in the opposite direction. The tangent of its rotation direction is perpendicular to the transport direction of the fabric. When the curved roller 5 rotates, it pushes and smooths the fabric through its arc-shaped roller body, so that the fabric can be rotated and flattened by the curved roller 5 during transport, which increases the stability of the fabric during transport. A drive wheel 501 is installed at the end of the support roller 201 without the rotating wheel 402. A rotating rod 502 is rotatably installed on the support platform 2. The drive wheel 501 and the rotating rod 502 are connected by a pulley assembly. The rotating rod 502 is connected to the shaft of one of the curved rollers 5 by a bevel gear set 504. The drive wheel 501 is coaxially connected to the support roller 201. When the support roller 201 rotates, it drives the drive wheel 501 to rotate together. The pulley assembly includes two pulley assemblies and a belt. One pulley is connected to the drive wheel 501, and the other pulley is connected to the rotating rod 502. The belt is used to drive the two pulleys so that when the drive wheel 501 rotates, it drives the rotating rod 502 to rotate. The bevel gear set 504 includes two perpendicular bevel gears. One bevel gear is connected to the rotating rod 502, and the other is connected to one of the two curved rollers 5, so that when the rotating rod 502 rotates, it can drive the curved roller 5 to rotate. When the device is in use, the motor drives the support roller 201 to rotate, which in turn drives the drive wheel 501 to rotate. This, in turn, drives the rotating rod 502 to rotate through the pulley assembly. This, in turn, drives the curved roller 5 to rotate through the bevel gear set 504. This allows the device to push and flatten the fabric during transport by the curved roller 5, making the fabric more stable during transport and winding, reducing the possibility of wrinkles during transport, and increasing the practicality of the device.

[0023] like Figure 5 and Figure 7 As shown, a portion of the structure on the support platform 2 is disclosed. In some embodiments, multiple ring plates 6 are installed on the support platform 2. The number of ring plates 6 is the same as the number of support rollers 201. The projection of the ring plates 6 is located at the connection between the support rollers 201 and the support platform 2. When the device is in use, in order to ensure the smoothness of the rotation of the support rollers 201, lubricating oil is applied to the connection between the support rollers 201 and the support platform 2. The present invention installs ring plates 6 at this point to cover the area where the lubricating oil is applied, reducing the possibility of the lubricating oil contaminating the fabric and increasing the practicality of the device. The height of the ring plate 6 is higher than the height of the highest point of the support roller 201. A sponge block 7 is installed inside the ring plate 6. The ring plate 6 contacts the support roller 201 through the sponge block 7. The ring plate 6 absorbs the lubricating oil located on the outer wall of the support roller 201 through the sponge block 7, which reduces the possibility of the lubricating oil being thrown out and splashing as the support roller 201 rotates. Compared with the lubricating oil being directly exposed, the lubricating oil can be absorbed and stored by the sponge block 7, which can reduce the evaporation rate of the lubricating oil, increase the durability of the lubricating oil, and increase the practicality of the device.

[0024] like Figure 5 and Figure 7 As shown, a portion of the structure on the support platform 2 is disclosed. In some embodiments, a unified plate 8 is slidably mounted on the support platform 2. The unified plate 8 is connected to the ring plate 6. Multiple ring plates 6 are uniformly connected through the unified plate 8, so that when the unified plate 8 slides, it can drive the ring plates 6 to slide together. An abutment plate 9 for contacting the curved roller 5 is mounted on the unified plate 8. A return spring 10 is installed between the abutment plate 9 and the support platform 2. When the curved roller 5 rotates until its bent part rotates to contact the abutment plate 9, it pushes the abutment plate 9, causing the abutment plate 9 to drive the unified plate 8 to slide. When the curved roller 5 rotates until it releases the contact with the abutment plate 9, the return spring 10 pushes the abutment plate 9 and the unified plate 8 to return to their original sliding position, thereby enabling the unified plate 8 and the ring plate 6 to reciprocate on the support platform 2. When the device is in use, the fabric is located below the curved roller 5 and above the ring plate 6. When the device transports the fabric, the fabric is flattened by the curved roller 5 above and rubbed by the reciprocating motion of the ring plate 6 below. The friction between the two also flattens the two sides of the fabric, further increasing the flatness of the fabric during transportation and increasing the practicality of the device. When the ring plate 6 slides, the sponge block 7 installed on it reduces the spread of lubricating oil to the rest of the support roller 201 body, thus reducing the possibility of lubricating oil coming into contact with the fabric.

[0025] like Figure 2 As shown, a portion of the structure on the clamping plate 4 is disclosed. In some embodiments, a mounting plate 11 is installed on the clamping plate 4, and a scraping plate 12 is installed on the mounting plate 11. The end of the scraping plate 12 contacts the scraping roller 401. The ends of the scraping plate 12 and the scraping roller 401 are pointed, so that when the scraping roller 401 rotates, the dust or lint attached to the surface of the scraping roller 401 is scraped off by the pointed end of the scraping plate 12. This allows the scraping roller 401 to maintain a relatively clean state when it comes into contact with the fabric, reducing the amount of dust and lint that has been scraped off from coming into contact with the fabric again, and increasing the practicality of the device. A fan 13 is installed on the support platform 2. The airflow direction of the fan 13 is perpendicular to the sliding direction of the clamping plate 4. After the dust and lint are loosened by the scraper plate 12, the airflow blown out by the fan 13 blows away the loosened dust and lint, further increasing the cleaning effect of the device.

[0026] like Figure 3 As shown, a portion of the structure on the support platform 2 is disclosed. In some embodiments, a limiting plate 14 is installed on the support platform 2. There is a gap between the limiting plate 14 and the support roller 201 for accommodating the fabric. The curved roller 5 is rotatably mounted on the limiting plate 14. The limiting plate 14 is erected above the support roller 201. Firstly, it is used to install the curved roller 5. Secondly, the limiting plate 14 is used to restrict the space above the support platform 2, so that when the fabric moves from the needle punching machine body 1 to the support platform 2, it is restricted by the limiting plate 14. This reduces the possibility of the fabric bulging due to excessive friction and speed difference during transportation, further increasing the practicality of the device.

[0027] like Figure 5 As shown, the specific structure of the contact plate 9 is disclosed. In some embodiments, an arc-shaped block 15 is installed at the end of the contact plate 9. The contact plate 9 contacts the curved roller 5 through the arc-shaped surface of the arc-shaped block 15. When the arc-shaped block 15 contacts the curved roller 5, the curved roller 5 can contact the arc-shaped block 15 more smoothly through the guidance of the arc-shaped surface of the arc-shaped block 15, so that the contact plate 9 can slide more stably when it is contacted, reducing the possibility of the contact plate 9 shaking when sliding.

[0028] like Figure 9 As shown, a portion of the structure on the support platform 2 is disclosed. In some embodiments, an ear plate 16 is installed on the support platform 2, and an insertion rod 17 is installed on the drive rod 306. The ear plate 16 has an insertion hole 18 that slides with the insertion rod 17. A pull spring 305 is sleeved on the outside of the insertion rod 17. The inner wall of the insertion hole 18 is used to restrict the side wall of the insertion rod 17, so that the insertion rod 17 can only slide on the support platform 2 in a straight line direction. In use, when the pull spring 305 pulls the drive rod 306, it can only slide in a straight line direction, which increases the stability of the drive rod 306 when sliding. In addition, the side wall of the insertion rod 17 restricts the inner ring of the pull spring 305, so that the pull spring 305 can only deform in the axial direction, which increases the stability of the pull spring 305 in use.

[0029] like Figure 10 As shown, in some embodiments, a cavity 19 is provided on the tension roller 302 so that the weight of the tension roller 302 is less than the pulling force exerted by the pull spring 305 on the pull rod 304. By setting the cavity 19 to reduce the weight of the tension roller 302, the fabric can more easily press the tension roller 302, and when there is a gap between the fabric and the tension roller 302, the pull spring 305 can also pull the pull rod 304 better, which improves the feasibility of the device.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
