[0016] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0017] To address the problems existing in the background art, this application proposes the following technical solution: a cutting device for plastic film production, including a base 1, a fixed frame 3 fixedly connected to the base 1, a conveying component in the fixed frame 3, a cutting component on the outside of the fixed frame 3, a baffle 9 on the base 1, and guardrails 13 on both sides of the baffle 9. The baffle 9 is detachably connected to the base 1, and an adjustment component is provided between the guardrails 13 and the baffle 9 to adjust the position of the guardrails 13 outside the baffle 9. The cutting component consists of a cylinder 7 fixedly connected to the fixed frame 3 and a cutting blade 8 fixedly connected to the output end of the cylinder 7. The base 1 serves as the basic support for the entire cutting device, providing a stable mounting platform for each component, ensuring that the device does not shake during operation and guaranteeing cutting accuracy. The fixed frame 3 on the base 1 is used to install the conveying component and the cutting component, and its stable structure allows the conveying and cutting actions to be carried out in coordination. The conveying component is responsible for smoothly conveying the plastic film to the cutting position, ensuring that the plastic film does not shift during the cutting process. The cutting assembly outside the fixed frame 3 is driven by a cylinder 7 to move the cutting blade 8 up and down, achieving rapid cutting of the plastic film. The cylinder 7 drives the cutting blade 8 with rapid response and uniform cutting force, ensuring a clean cut and preventing burrs or tears in the plastic film. The baffle 9 on the base 1 is used to position the ends of the conveyed plastic film, ensuring that each cut segment of plastic film is of consistent length.

[0018] The side guards 13 on both sides of the baffle 9 prevent the plastic film from shifting from the sides, further ensuring cutting accuracy. The detachable connection between the baffle 9 and the base 1 allows for easy adjustment of the baffle 9's position according to different cutting length requirements, enhancing the equipment's flexibility. The adjustment mechanism between the side guards 13 and the baffle 9 allows for adjustment of the spacing between the side guards 13 according to the width of the plastic film, enabling the equipment to adapt to plastic films of different widths and expanding its applicability. The overall structure is compact, with all components working collaboratively to form a complete process from conveying and positioning to cutting, improving the efficiency and quality of plastic film cutting.

[0019] In this embodiment, the conveying assembly consists of two sets of conveying rollers 5 rotatably connected to the outside of the fixed frame 3. Two sets of gears 6 are rotatably connected to the outside of the fixed frame 3, and the gears 6 are coaxially and fixedly connected to the conveying rollers 5. A motor 4 is fixedly connected to the outside of the fixed frame 3, and the output end of the motor 4 is fixedly connected to the conveying rollers 5. The two sets of conveying rollers 5 are arranged vertically opposite each other. The plastic film passes between the two sets of conveying rollers 5, and the rotation of the conveying rollers 5 drives the plastic film forward. The rotatable connection of the conveying rollers 5 to the outside of the fixed frame 3 ensures smooth rotation and reduces frictional damage to the plastic film. The two sets of gears 6 outside the fixed frame 3 are coaxially and fixedly connected to the two sets of conveying rollers 5, and the two sets of gears 6 mesh with each other. When one set of conveying rollers 5 rotates, the gears 6 drive the other set of conveying rollers 5 to rotate synchronously in the opposite direction, thus achieving the clamping and conveying of the plastic film. This gear-driven transmission system ensures that the two sets of conveyor rollers 5 rotate at the same speed, preventing stretching or wrinkling of the plastic film due to speed differences and ensuring smooth conveying. The motor 4 external to the fixed frame 3 provides power to the conveyor rollers 5, with its output directly and fixedly connected to the rollers 5, ensuring efficient and stable power transmission. The speed of the motor 4 can be adjusted according to production needs, thereby controlling the conveying speed of the plastic film and matching it with the cutting rhythm of the cutting components. This ensures precise cutting lengths for each segment of plastic film, avoiding inconsistencies in length and improving cutting consistency and stability.

[0020] In this embodiment, a guide roller 2 is rotatably connected to the base 1. Multiple sets of positioning holes 10 are provided on both sides of the base 1, and mounting grooves 14 are provided on both sides of the baffle 9. A positioning block 15 is rotatably connected to the mounting groove 14. Magnets 16 are fixedly connected to both ends of the positioning block 15, and iron pieces are fixedly connected to both the mounting groove 14 and the positioning holes 10. The guide roller 2 on the base 1 is located in front of the conveying assembly and guides the plastic film about to enter the conveying roller 5, allowing the plastic film to smoothly enter between the conveying rollers 5 and preventing wrinkles or displacement of the plastic film due to improper angle. The rotatable connection of the guide roller 2 reduces friction with the plastic film, preventing scratches on the surface of the plastic film. The multiple sets of positioning holes 10 on both sides of the base 1 provide multiple fixing points for adjusting the position of the positioning block 15. The positioning block 15, which is rotatably connected in the mounting grooves 14 on both sides of the baffle 9, can be inserted into the positioning holes 10 at different positions to adjust the position of the baffle 9, thereby changing the cutting length of the plastic film. When it is necessary to adjust the cutting length, rotate the positioning block 15 to disengage it from the positioning hole 10, move the baffle 9 to the appropriate position, and then rotate the positioning block 15 to engage with the corresponding positioning hole 10. The magnets 16 at both ends of the positioning block 15 attract the iron pieces in the mounting groove 14 and positioning hole 10, firmly fixing the positioning block 15 in the positioning hole 10. This prevents the positioning block 15 from loosening and shifting during equipment operation, ensuring the stability of the cutting length. This positioning structure is easy to operate, requiring no tools to adjust the position of the baffle 9, greatly improving the equipment's adaptability to different cutting length requirements and increasing operational efficiency.

[0021] In this embodiment, the adjusting component is a bidirectional threaded rod 11 rotatably connected to the top of the baffle 9. Two nut blocks 12 are externally threaded onto the bidirectional threaded rod 11, and each nut block 12 is fixedly connected to a corresponding enclosure 13. A guide rod 17 is fixedly connected to the top of the baffle 9, passing through the nut blocks 12. The bidirectional threaded rod 11 in the adjusting component is rotatably connected to the top of the baffle 9, with its two ends having opposite thread directions. When the bidirectional threaded rod 11 is rotated, the two externally threaded nut blocks 12 slide towards or away from each other along the threaded rod. The nut blocks 12 are fixedly connected to the enclosures 13 on both sides, thereby causing the enclosures 13 to move synchronously, thus adjusting the spacing between the enclosures 13. The guide rod 17 at the top of the baffle 9 passes through the nut block 12, guiding the sliding of the nut block 12 and preventing it from rotating with the threaded rod. This ensures that the enclosure 13 can move smoothly along a straight line, avoiding any deviation that could affect the positioning effect. This method of adjusting the spacing of the enclosure 13 via the bidirectional threaded rod 11 is simple to operate. Simply rotating the threaded rod allows for precise adjustment of the distance between the two enclosures 13, ensuring that the enclosure 13 fits snugly against the sides of plastic films of different widths. This effectively prevents the plastic film from shifting during conveying and cutting, ensuring that the plastic film is always in the correct cutting position and improving cutting accuracy. Furthermore, this adjustment method is responsive and can quickly adapt to the cutting needs of plastic films of different widths, enhancing the equipment's versatility.

[0022] The usage method of this embodiment is as follows: First, adjust the dimensions according to the width and length of the plastic film to be cut. For the width dimension, rotate the double-threaded rod 11 on the top of the baffle 9, which will cause the two nut blocks 12 and the guardrail 13 to slide towards or away from each other until the distance between the two guardrails 13 is adapted to the width of the plastic film. The guide rod 17 ensures that the guardrail 13 moves smoothly. After adjustment, the guardrail 13 can effectively restrict the lateral movement of the plastic film. For the desired length, place the baffle 9 at a suitable position on the base 1, rotate the positioning blocks 15 on both sides of the baffle 9 so that the positioning blocks 15 are engaged in the corresponding positioning holes 10 on the base 1, and the magnets 16 on the positioning blocks 15 are attracted and fixed to the iron pieces in the positioning holes 10, thus completing the position fixation of the baffle 9 and ensuring that the plastic film can be accurately positioned when it is delivered to the baffle 9, thus ensuring consistent cutting length. After adjustment, the motor 4 of the conveying assembly is started. The motor 4 drives the conveying rollers 5 to rotate, and the gear 6 drives the two sets of conveying rollers 5 to rotate synchronously in opposite directions, smoothly conveying the plastic film forward. After being guided by the guide roller 2, the plastic film enters the conveying rollers 5 and is then conveyed to the area below the cutting assembly. When the end of the plastic film touches the baffle 9, the cylinder 7 of the cutting assembly drives the cutting blade 8 downward to cut the plastic film. The cylinder 7 ensures fast and powerful cutting with a clean cut. Afterward, the cutting blade 8 returns to its original position, and the conveying assembly continues to convey the plastic film, repeating the above process to achieve continuous cutting. The entire operation is simple and convenient, with flexible adjustments, and can quickly adapt to the cutting needs of plastic films of different sizes, ensuring cutting quality and efficiency.
