Description

Technical Field

[0001] This utility model relates to the field of reflective film processing equipment, and in particular to a reflective film cutting machine. Background Technology

[0002] Reflective film is a functional material widely used in traffic signs, billboards, vehicle wraps, and other fields. Its surface has high reflectivity, significantly improving visibility under light. Reflective film is typically produced and stored in rolls, but in practical applications, it needs to be cut to meet specific requirements. The cutting process not only demands high precision but also must accommodate different sizes and shapes; therefore, efficient and precise cutting equipment is a key tool in reflective film processing.

[0003] Currently, most reflective film cutting machines on the market are designed for equidistant cutting of rolls of reflective film and can be programmed with different cutting lengths via a control system. These machines typically consist of a feeding system, a cutting system, and a control system. The feeding system is driven by a servo motor to ensure the material is fed to the set length; the cutting system uses high-precision cutting blades to cut the reflective film. In addition, some machines are equipped with pressure rollers to flatten the material during the cutting process, improving cutting accuracy. While these machines meet the basic requirements for reflective film cutting to a certain extent, they still have some limitations in practical use.

[0004] While existing reflective film cutting machines perform relatively stably in long-distance cutting, they exhibit significant shortcomings in short-distance cutting. The main problem lies in the constant distance between the auxiliary pressure roller and the cutting position, which cannot adapt to varying cutting lengths. When cutting rolls of reflective film over short distances, the material's inherent bending characteristics prevent the pressure roller from effectively flattening the area near the cutting position, leading to decreased cutting accuracy and even cutting deviations or material waste. Furthermore, the inertia of the feeding system and material springback further exacerbate cutting instability during short-distance cutting. These issues severely impact the equipment's applicability and production efficiency in short-distance cutting, necessitating technological improvements to address them. Utility Model Content

A collection box is slidably connected to the bottom of the cutting machine, and a movable plate is slidably connected to the middle of the cutting machine. Pressure plates are connected to both the left and right sides inside the cutting machine. The top surfaces of the left and right ends of the movable plate are limited to the pressure plates. A guide component for limiting the width of the reflective film is provided at the rear end of the movable plate. A pressure roller is rotatably connected to the movable plate.

A controller is installed on the cutting machine to control the adjustment component.

[0007] Optionally, the guide assembly includes an adjusting frame connected to the movable plate, with two limiting blocks slidably connected inside the adjusting frame, and an adjusting screw threadedly connected to the top of each limiting block, the adjusting screw engaging with the adjusting frame.

[0008] Optionally, the adjusting assembly includes a lead screw, a limit groove is opened at the rear end of the cutting machine, a motor is installed at the rear of the cutting machine, the motor is wired to the controller, a moving block is slidably connected in the limit groove, the top of the moving block is fixedly connected to the movable plate, the lead screw is rotatably connected in the limit groove of the cutting machine and threadedly connected to the moving block, and the rear end of the lead screw passes through the cutting machine and is connected to the output shaft of the motor.

Detailed Implementation

[0020] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0021] Example: A reflective film cutting machine, such as Figures 1-4 As shown, the device includes a cutting machine 1, a cutter 2, a drive roller 3, a collection box 4, a movable plate 5, a pressure plate 6, a guide assembly 8, an adjustment assembly, a controller 13, and a pressure roller 17. The cutting machine 1 is equipped with a cutter 2 and a drive roller 3, with the cutter 2 located in front of the drive roller 3. The collection box 4 is slidably connected to the bottom of the cutting machine 1. When the remaining waste material of the reflective film roll is not long enough, the drive roller 3 conveys the reflective film backward, and the waste material falls into the collection box 4. The movable plate 5 is slidably connected in the middle of the cutting machine 1. Pressure plates 6 are connected to both the left and right sides of the cutting machine 1. The top surfaces of the left and right ends of the movable plate 5 are limited to the pressure plates 6. The rear end of the movable plate 5 is equipped with a guide assembly 8 for limiting the width of the reflective film. The pressure roller 17 is rotatably connected to the movable plate 5. An adjustment assembly for adjusting the front and rear positions of the movable plate 5 is installed inside the cutting machine 1. The controller 13 is installed on the cutting machine 1 and is used to control the adjustment assembly.

[0022] like Figure 4As shown, the guide assembly 8 includes an adjusting frame 81, limiting blocks 82, and adjusting screws 83. The adjusting frame 81 is connected to the movable plate 5. Two limiting blocks 82 are slidably connected inside the adjusting frame 81. The adjusting screws 83 are threadedly connected to the top of the limiting blocks 82, and the adjusting screws 83 are in a pressing fit with the adjusting frame 81. According to the width requirement of the reflective film, the adjusting screws 83 are loosened, allowing the limiting blocks 82 to slide freely within the adjusting frame 81. The bottom of the limiting blocks 82 slides in contact with the movable plate 5, ensuring smooth adjustment of the position of the limiting blocks 82. The distance between the two limiting blocks 82 is consistent with the width of the reflective film, ensuring that the reflective film will not shift during the conveying process and improving cutting accuracy.

[0023] like Figure 3 As shown, the adjustment assembly includes a moving block 10, a lead screw 11, and a motor 12. A limit groove 9 is opened at the rear end of the cutting machine 1. The motor 12 is installed at the rear of the cutting machine 1 and is wired to the controller 13. The moving block 10 is slidably connected within the limit groove 9. The top of the moving block 10 is fixedly connected to the movable plate 5. The lead screw 11 is rotatably connected within the limit groove 9 of the cutting machine 1 and threadedly connected to the moving block 10. The rear end of the lead screw 11 passes through the cutting machine 1 and connects to the output shaft of the motor 12. When it is necessary to adjust the distance between the pressure roller 17 and the drive roller 3 to accommodate different cutting lengths, the rotational motion of the lead screw 11 is converted into the linear motion of the moving block 10. The moving block 10 slides within the limit groove 9, driving the movable plate 5 to move back and forth, thereby adjusting the position of the pressure roller 17. The distance between the pressure roller 17 and the drive roller 3 is precisely set to ensure that the reflective film remains flat before cutting, improving cutting stability.

[0024] like Figure 2 As shown, it also includes fixing screws 7 and external hexagonal sleeves 15. The fixing screws 7 are threadedly connected to the left and right sides of the movable plate 5. The bottom of the fixing screws 7 is pressed into the cutting machine 1, and the top of the fixing screws 7 is fitted with external hexagonal sleeves 15. After the position of the movable plate 5 is adjusted, the operator uses the external hexagonal sleeves 15 to tighten the fixing screws 7, which enhances the stability of the movable plate 5 and prevents it from shifting due to vibration or material tension during the cutting process, ensuring the working effect of the pressure roller 17 and the guide assembly 8.

[0025] like Figure 3 As shown, it also includes a handle 14, which is connected to the side of the collection box 4. When the collection box 4 is full, the worker can easily pull out the collection box 4 using the handle 14 to clean up the waste. The handle 14 makes the movement of the collection box 4 more convenient and improves the efficiency of the equipment.

[0026] like Figure 2As shown, it also includes a scale 16, which is set on the top of the pressure plate 6. By observing the scale 16 on the top of the pressure plate 6, the operator can accurately control the movement distance of the movable plate 5, and quickly adjust the position of the pressure roller 17 without relying on complicated measuring tools, thus ensuring the accuracy of the cutting length.

[0027] The worker pulls out the reflective film to be cut. After passing through the two limiting blocks 82 of the guide assembly 8 and the pressure roller 17, it is finally cut by the cutter 2 when passing through the drive roller 3. According to the width of the reflective film, the distance between the two limiting blocks 82 is adjusted by loosening the adjusting screw 83. Then, the limiting blocks 82 are moved left and right, and the bottom of the limiting blocks 82 slides into contact with the movable plate 5. After adjustment, the fixing screw 7 is tightened to limit the width of the reflective film. For different cutting length requirements, the motor 12 is started by the controller 13. The motor 12 drives the lead screw 11 to rotate. During the rotation of the lead screw 11, the moving block 10 is pushed to move back and forth, thereby driving the movable plate 5 to move back and forth, thereby adjusting the position between the pressure roller 17 and the drive roller 3 to ensure the flatness of the reflective film before cutting. The movable plate 5 is ensured to move smoothly by the pressure plate 6, and the adjusted distance can be directly observed by the scale 16. After the adjustment is completed, the movable plate 5 is further fixed by the fixing screw 7 with the external hexagonal sleeve 15 to ensure the stability of the pressure roller 17 during the cutting process.
