On large vehicles such as trucks, trailers, and buses, reflective strips are usually attached to the edge of the vehicle body profile to show the outline and warn other road users, especially at night or in low visibility environments, which can effectively reduce traffic accidents. The high reflectivity of reflective film makes it an important part of vehicle safety markings.

[0003] Currently, there are some devices on the market for slitting reflective film. These devices usually include a fixing device and a rotating mechanism, which can fix and rotate the long reflective film tape, and achieve equidistant cutting through the cutting device.

Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example: A reflective film slitter, such as Figures 1-3 As shown, the slitting machine includes a slitting body 1, a placement roller 2, a cutting assembly 3, a mounting frame 4, a motor 5, a lead screw 6, a toggle component 7, a discharge ramp 8, a collection frame 9, a controller 10, and a buffer assembly. The slitting body 1 is equipped with a driver and a placement roller. The driver drives the placement roller to rotate, and the placement roller is equipped with a pneumatic external support clamp for fixing the rubber roller. The cutting assembly 3 for equidistant cutting is installed on the slitting body 1. The mounting frame 4 is connected to the right end of the slitting body 1, and the motor 5 is installed on the mounting frame 4. One end of the lead screw 6 is connected to the output shaft of the motor 5, and the other end is rotatably connected to the left end of the slitting body 1. A toggle component 7 is threaded onto the lead screw 6, and the top of the toggle component 7 is sleeved on the placement roller 2. The discharge ramp 8 is connected to the mounting frame 4. A collection frame 9 is placed on the rear side of the slitting body 1. The controller 10 is installed on the slitting body 1, and the controller 10 is wired to both the motor 5 and the driver. A buffer assembly for assisting discharge is provided on the top of the toggle component 7. The placement roller 2 is pneumatically opened and fixed to the rubber roller by an external support clamp. The driver drives the placement roller 2 to rotate, causing the rubber roller to rotate synchronously and providing power for cutting. The cutting assembly 3 cuts the rubber roller at preset intervals to ensure that the cut rubber rolls are of consistent size. The motor 5 drives the lead screw 6 to rotate through the output shaft. The lead screw 6 drives the actuating component 7 to move along the placement roller 2, pushing the cut rubber roller towards the discharge inclined plate 8. The discharge inclined plate 8 is used to receive the rubber roller exiting from the placement roller 2 and slides it into the collection frame 9 through its inclined design. The collection frame 9 is used to centrally store the cut rubber rolls for easy retrieval later. The controller 10 is wired to the motor 5 and the driver to control the start and stop of the equipment, the speed, and the cutting interval, realizing automated operation.

[0021] likeFigure 1 and Figure 3 As shown, the buffer assembly includes a fixed disc 11, a return spring 12, a turntable 13, and a connecting ring 131. The fixed disc 11 is sleeved on the placement roller 2, and its left end is slidably connected to the top of the actuating member 7 via a limiting rod. The return spring 12 is sleeved on the limiting rod, with one end connected to the actuating member 7 and the other end connected to the fixed disc 11. The connecting ring 131 is rotatably connected to the right side of the fixed disc 11, and the turntable 13 is connected to the right side of the connecting ring 131. During discharge, the squeezing action of the buffer assembly and the rubber roller pushes the turntable 13 and the fixed disc 11 to the left. The fixed disc 11 slides on the limiting rod and compresses the return spring 12. During the compression of the return spring 12, the connecting ring 131 can rotate freely, ensuring that the rubber roller does not drive the fixed disc 11 to rotate together when it rotates. The buffering effect of the return spring 12 avoids additional frictional resistance. When the actuating element 7 stops pushing, the return spring 12 rebounds, pushing the fixed disc 11 and the turntable 13 back to their original positions, preparing for the next material discharge.

[0022] like Figure 3 As shown, it also includes ball bearings 14. Several ball bearings 14 are arranged between the actuating element 7 and the placement roller 2, creating rolling friction between the ball bearings 14 and the placement roller 2. When the actuating element 7 moves along the screw 6, the ball bearings 14 roll on the surface of the placement roller 2, significantly reducing the friction between the actuating element 7 and the placement roller 2, ensuring smooth movement of the actuating element 7. Simultaneously, when the placement roller 2 rotates, the ball bearings 14 also roll, avoiding direct contact friction between the actuating element 7 and the placement roller 2, thereby extending the service life of the equipment and improving the smoothness of material discharge.

[0023] like Figure 3 As shown, it also includes a protective sleeve 15, with its right end connected to the fixed disc 11 and its left end connected to the actuating element 7. During the movement of the actuating element 7, the protective sleeve 15 can effectively prevent external dust or impurities from entering the buffer assembly, thus avoiding affecting the normal operation of the return spring 12 and the connecting ring 131.

[0024] like Figure 3 As shown, it also includes a sponge pad 16, which is installed on the right side of the turntable 13. When the rubber roller comes into contact with the sponge pad 16, the sponge pad 16 can absorb the impact force of the rubber roller, preventing the rubber roller from being deformed or damaged due to collision during movement. At the same time, the softness of the sponge pad 16 can also reduce the friction between the rubber roller and the turntable 13, ensuring that the rubber roller can rotate smoothly during movement and avoiding jamming.

[0025] like Figure 1As shown, the device also comprises a guide plate 17 arranged on the discharge inclined plate 8, which can guide the movement direction of the rubber roller when the rubber roller is withdrawn from the placing roller 2 and falls onto the discharge inclined plate 8, and the guide plate 17 is provided with protrusions and grooves, which can reduce the contact area between the rubber roller and the discharge inclined plate 8, thereby reducing the friction and ensuring that the rubber roller can accurately slide into the collection frame 9. The design of the guide plate 17 avoids the deviation or accumulation of the rubber roller during the discharging process, and improves the efficiency and neatness of the discharging process.

[0026] After the staff puts the rubber roller to be cut on the placing roller 2, the pneumatic outwardly expanding clamp is started to expand the rubber roller from the inside and fix the rubber roller. Then, the driver is started to drive the placing roller 2 to rotate and drive the rubber roller to rotate synchronously. The cutting assembly 3 cuts the rubber roller at equal intervals according to the preset interval. After the cutting is completed, the driver and the pneumatic outwardly expanding clamp are closed, the motor 5 is started to drive the screw rod 6 to rotate, and the screw rod 6 drives the pusher 7 to move to the right. The pusher 7 is in contact with the placing roller 2 through the ball 14 and moves to the right along the screw rod 6, and pushes the cut rubber roller to move to the direction of the discharge inclined plate 8. The end of the rubber roller first contacts the sponge pad 16, and the buffer assembly ensures that the rubber roller rotates stably and reduces friction during the movement through the cooperation of the return spring 12 and the connecting ring 131. When the rubber roller completely exits the placing roller 2, it falls onto the discharge inclined plate 8 and slides into the collection frame 9 through the guide plate 17. Finally, the motor 5 is reversed, and the pusher 7 moves to the left and resets under the action of the return spring 12, completing a cutting and discharging cycle. The whole process does not require manual intervention, realizes automatic operation, and significantly improves the production efficiency and product quality.

Any equivalent replacement made within the principles of the present application shall be included in the protection scope of the present application.
