Description
Technical Field
[0001] This utility model relates to a plastic flat wire splitting machine, specifically a plastic flat wire splitting machine, and belongs to the technical field of plastic flat wire splitting machines. Background Technology
[0002] Plastic flat yarn has a wide range of applications in industry and daily life, such as weaving various packaging bags, shade nets, ropes, etc. Its production process usually includes film formation, film slitting, flat yarn stretching and shaping, and flat yarn winding or conveying to warp knitting machines. The slitting machine plays a key role in this process, undertaking the important tasks of film slitting and flat yarn stretching and shaping.
[0003] However, when traditional slitting machines cut films, the moment the blades come into contact with the film, due to the plastic or brittle properties of the material, the blades may cause some material to break or peel off when squeezing or shearing the film, forming fine debris. This debris adheres to the surface of the flat yarn, which may cause the surface of the flat yarn to be rough and uneven in thickness, affecting the strength and appearance of the subsequent woven products. In addition, the slitting point of the slitting blade is often fixed. After working for a long time, the slitting blade will heat up due to friction. This may not only burn the film yarn due to excessive temperature, but also cause the slitting point of the slitting blade to wear down, dull the blade edge, increase the frequency of blade replacement, and increase production costs. Utility Model Content
[0004] The purpose of this invention is to provide a plastic flat yarn splitting machine to solve the above problems. It can remove the debris generated during the splitting process, so as to avoid the debris affecting the strength and appearance of the subsequent woven products. At the same time as removing debris, it can accelerate the air circulation around the splitting blade, thereby avoiding the splitting blade temperature from getting too high and improving the safety of use.

[0024] As a technical optimization of this utility model, two guide shafts 7 are rotatably connected between the two support seats 1. Therefore, the plastic film before slitting can be guided by one guide shaft 7, and the flat wire after slitting can be guided by the other guide shaft 7.
[0025] As a technical optimization of this utility model, the blocking structure 4 includes a connecting seat 401 and a screw 402. Two connecting seats 401 are fixedly connected to the connecting box 301, and a screw 402 is fixedly connected to the connecting seat 401. A baffle 403 is movably connected to the outside of the screw 402. The baffle 403 engages with the connecting seat 401, thus positioning the baffle 403. The baffle 403 abuts against the outer frame 303 and the collection box 307. Therefore, the baffle 403 can fix both the outer frame 303 and the collection box 307. A knob 404 is threadedly connected to the screw 402. The knob 404 abuts against the baffle 403, thus fixing the baffle 403 through the abutment between the knob 404 and the baffle 403.
[0026] As a technical optimization of this utility model, the slitting structure 5 includes a support plate 501 and a motor 502. Two support plates 501 are fixedly connected to the connecting column 2, and the two support plates 501 can support the connecting shaft 505. The two support plates 501 are rotatably connected to the same connecting shaft 505. Therefore, when the connecting shaft 505 rotates, multiple second synchronous pulleys 507 can rotate synchronously. Multiple connecting plates 506 are fixedly connected to the connecting column 2, and a rotating shaft 509 is rotatably connected to the connecting plate 506. The rotating shaft 509 is provided with a fixing structure. Structure 6: A stop block 510 is engaged on the rotating shaft 509, and a slitting blade 511 abuts against the stop block 510 and the rotating shaft 509, so that the plastic film can be slit by the slitting blade 511. A second synchronous pulley 507 is fixedly connected to the rotating shaft 509, and a plurality of second synchronous pulleys 507 are fixedly connected to the connecting shaft 505. A second synchronous belt 508 is wound between the second synchronous pulley 507 on the rotating shaft 509 and the adjacent second synchronous pulley 507 on the connecting shaft 505, so that when the connecting shaft 505 rotates, the plurality of slitting blades 511 can rotate simultaneously.
[0027] As a technical optimization of this utility model, a motor 502 is installed on one of the support plates 501. A first synchronous pulley 503 is fixedly connected to the output shaft of the motor 502. A first synchronous pulley 503 is fixedly connected to the connecting shaft 505. A first synchronous belt 504 is wound between the two first synchronous pulleys 503. Therefore, when the output shaft of the motor 502 rotates, the connecting shaft 505 can rotate, thereby realizing the control of the connecting shaft 505.
[0028] As a technical optimization of this utility model, the overall cross-section of the stop block 510 is T-shaped, so the stop block 510 can block the slitting blade 511. The engaging part of the stop block 510 and the rotating shaft 509 is a quadrangular prism, so the stop block 510 and the slitting blade 511 can rotate together with the rotating shaft 509. The stop block 510 passes through the slitting blade 511, and the connecting shaft 505 passes through the connecting plate 506.
[0029] As a technical optimization of this utility model, the multiple cutting blades 511 are linearly and equidistantly distributed, and an air inlet 306 is provided directly below each cutting blade 511, so that the cut debris can easily enter the interior of the connecting pipe 305.
[0030] As a technical optimization of this utility model, the fixing structure 6 includes a slider 601 and an annular groove 602. The slider 601 is slidably connected to the stop block 510, so the slider 601 can block the two locking blocks 603, making the locking blocks 603 engage with the rotating shaft 509. The slider 601 is provided with an annular groove 602, so the locking blocks 603 can move into the interior of the annular groove 602, thereby facilitating the removal of the stop block 510 from the interior of the rotating shaft 509. The slider 601 is slidably connected to the stop block 510. Two locking blocks 603 are connected in a moving connection. One end of each locking block 603 engages with the rotating shaft 509, thereby fixing the stop block 510. The other end of each locking block 603 abuts against the slider 601. A spring 604 is fixedly connected to the slider 601, and the spring 604 abuts against the rotating shaft 509. Therefore, under the action of the spring 604, the slider 601 can always abut against the two locking blocks 603 when it is not pressed.
[0031] As a technical optimization of this utility model, the cross-section of the locking block 603 near the end of the rotating shaft 509 is trapezoidal, so that when the stop block 510 moves, the rotating shaft 509 can automatically abut against the locking block 603 and slide on the stop block 510. The two locking blocks 603 are symmetrically distributed about the middle of the rotating shaft 509. The engagement between the two locking blocks 603 and the rotating shaft 509 can improve the stability of fixing the stop block 510.
[0032] In use, this invention allows two support bases 1 to be installed on a flat wire slitting machine. One guide shaft 7 guides the plastic film before slitting, and the other guide shaft 7 guides the slitting flat wire. During slitting, the motor 502 is started, and the output shaft of the motor 502 rotates, driving the first synchronous pulley 503 to rotate. The first synchronous pulley 503 drives another first synchronous pulley 503 to rotate via the first synchronous belt 504. The rotation of the other first synchronous pulley 503 drives the rotating shaft 509 to rotate, which in turn drives multiple second synchronous pulleys 507 to rotate. The rotation of the second synchronous pulleys 507 on the rotating shaft 509 drives the first second synchronous pulleys 507 on the rotating shaft 509 via the second synchronous belt 508. The rotation of the second synchronous pulley 507, located on the rotating shaft 509, drives the rotating shaft 509 to rotate. The rotation of the rotating shaft 509 drives the stop block 510 to rotate, which in turn drives the slitting blade 511 to rotate. The rotation of multiple slitting blades 511 will achieve the slitting of the plastic film. During the slitting process, two fans 302 can be started simultaneously. Under the action of the fans 302, the debris generated during the slitting process will enter the interior of the connecting pipe 305 with the air through the air inlet 306, and then enter the interior of the connecting box 301 from the interior of the connecting pipe 305. After entering the interior of the connecting box 301, the debris will be filtered by the filter screen 304, and the filtered air will be discharged from the fan 302. The filtered debris will fall into the collection box. The internal structure of collection box 307 centrally collects debris, thus removing it from the slitting process and preventing it from adhering to the flat yarn surface. This ensures the strength and appearance of the subsequent woven products. Simultaneously, it accelerates the airflow around the slitting blade 511, preventing damage caused by prolonged operation at high temperatures and avoiding damage to the flat yarn, thereby improving safety. To clean the debris collected inside collection box 307, knob 404 is rotated. Once a certain distance is created between knob 404 and baffle 403, baffle 403 can be pulled to prevent it from engaging with connecting seat 401. Then, baffle 403 can be rotated to prevent it from obstructing collection box 307. Finally, the debris can be removed from the collection box. The collection box 307 can be pulled out from the inside of the connecting box 301 to empty debris. At the same time, the outer frame 303 can be pulled out from the inside of the connecting box 301 to clean the filter screen 304. Regular cleaning of the filter screen 304 can prevent clogging and ensure the filtration effect. When the slitting blade 511 needs to be replaced, the slider 601 can be pressed, the spring 604 will retract, and when one end of the slider 601 abuts against the rotating shaft 509, the locking block 603 will be located on one side of the annular groove 602. Then, the slitting blade 511 can be held and the stop block 510 can be pulled out from the inside of the rotating shaft 509. Finally, the slitting blade 511 can be removed from the stop block 510, thereby realizing the quick disassembly of the slitting blade 511 and facilitating the replacement of the slitting blade 511.
