Description

Technical Field

[0001] This utility model relates to the field of PVC electrostatic film technology, specifically a segmented cutting device. Background Technology

[0002] PVC electrostatic film is a type of PVC film with electrostatic properties, widely used in packaging, protection, printing, and electronic equipment. Its main characteristic is that its surface carries static electricity, enabling it to attract dust and foreign objects, providing dustproof, scratch-resistant, and protective functions. During the processing of PVC electrostatic film, rolls of material need to be cut into multiple smaller rolls for better subsequent use, packaging, and distribution. Currently, the cutting process often involves placing the roll of PVC electrostatic film on the outside of a support shaft, and then rotating the PVC electrostatic film to contact the blade to achieve cutting. This requires assembling the roll of PVC electrostatic film with the support shaft, which can be very difficult manually due to the weight and volume of the roll, easily leading to operator fatigue or accidental injury.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: a segmented cutting device, comprising: a support frame 1; a support roller assembly placed on top of the support frame 1, the support roller assembly including a driven roller 3 and an active roller 2 for driving the material to rotate, the active roller 2 and the driven roller 3 being rotatably mounted on top of the support frame 1 via bearings, and the active roller 2 and the driven roller 3 being parallel; a support plate 5 being mounted on one side of the support frame 1 via bolts, and a pressing roller 11 for limiting the material from the top being flexibly arranged on one side of the support plate 5; a cutting machine 9 being flexibly arranged on one side of the support plate 5, the cutting machine 9 consisting of a motor and a cutting blade, the cutting blade being fixedly connected to the output end of the motor, a pushing part being placed on the outside of the support frame 1, the pushing part including a vertical rod 18, a sliding sleeve being slidably connected to the middle of the vertical rod 18, a bolt for fixing the position of the sliding sleeve being threadedly connected to the outside of the sliding sleeve, a crossbar 19 being mounted on the outside of the sliding sleeve via bolts, and a positioning frustum 20 being rotatably connected to one side of the crossbar 19 for positioning and pushing the material to move.

[0024] It should be noted that in this embodiment, a controller and a control switch are provided. The rolled PVC electrostatic film is placed above the active roller 2 and the driven roller 3. One end of the rolled PVC electrostatic film is connected to the positioning frustum 20. The pressing roller 11 moves downward to press the rolled PVC electrostatic film from the top. This achieves the rolled PVC electrostatic film being clamped between the active roller 2, the driven roller 3 and the pressing roller 11. When the active roller 2 rotates, the rolled PVC electrostatic film rotates with the active roller 2 under the action of friction. The cutting machine 9 is controlled to move downward, and the cutting blade contacts the rolled PVC electrostatic film to cut it.

[0025] In one embodiment, such as Figure 1 , 2As shown in Figures 1 and 3, the support roller assembly also includes a drive motor 4 fixedly connected to one end of the support frame 1, and the output end of the drive motor 4 is fixedly connected to the drive roller 2.

[0026] It should be noted that in this embodiment, the drive motor 4 drives the active roller 2 to rotate. The active roller 2 and the driven roller 3 support the rolled PVC electrostatic film. Under the action of friction, the active roller 2 drives the rolled PVC electrostatic film to rotate, and the rolled PVC electrostatic film drives the driven roller 3 to rotate. Together with the pressure roller 11, the rolled PVC electrostatic film rotates in place, which is convenient for cutting with the cutting machine 9.

[0027] In one embodiment, such as Figure 2 , 3 As shown in Figure 4, a fixing plate 13 is fixedly connected to the outer side of the support plate 5. A dual-axis cylinder 15 is slidably connected to the bottom of the fixing plate 13. A limiting rod 14 that is slidably connected to the fixing plate 13 is fixedly connected to one end of the dual-axis cylinder 15. A groove is provided on the outer side of the limiting rod 14. A fastening bolt for locking the groove is threadedly connected to the outer side of the fixing plate 13. A lifting plate 10 is fixedly connected to the output end of the dual-axis cylinder 15. The lifting plate 10 is slidably connected to the support plate 5. A pressure roller 11 is installed at the bottom of one end of the lifting plate 10.

[0028] It should be noted that in this embodiment, a metal plate is fixedly connected to the outside of the dual-axis cylinder 15, and a metal rod that is slidably connected to the metal plate is fixedly connected to the bottom of the fixing plate 13. By adjusting the dual-axis cylinder 15 up and down, the position of the limiting rod 14 inside the fixing plate 13 is adjusted. The limiting rod 14 is fixed by bolts, thereby fixing the dual-axis cylinder 15 at the height position outside the support plate 5. This adjusts the position of the pressing roller 11. There are two pressing rollers 11. Each pressing roller 11 consists of an n-shaped bracket and a roller shaft that rotates inside the n-shaped bracket. When pressing the rolled PVC electrostatic film from the top, the dual-axis cylinder 15 drives the lifting plate 10 to move downward. The support plate 5 is provided with a sliding groove that cooperates with the lifting plate 10. The lifting plate 10 drives the pressing roller 11 to move downward, restricting the rolled PVC electrostatic film from the top, so that it can rotate without moving in the Z-axis direction.

[0029] In one embodiment, such as Figure 1 , 2 As shown in Figure 3, a guide rail 6 is fixedly connected to one side of the support plate 5 and above the drive roller 2. A slider 7 is slidably connected to the outside of the guide rail 6. The cutting machine 9 is fixedly connected to the slider 7. A cylinder 8 for driving the slider 7 to slide is fixedly connected to one side of the support plate 5.

[0030] It should be noted that, in this embodiment, when the height of the cutting machine 9 is adjusted, the cylinder 8 drives the slider 7 to slide on the outside of the guide rail 6, and the slider 7 drives the cutting machine 9 to rise and fall, thereby performing the cutting operation on the roll of PVC electrostatic film below.

[0031] In one embodiment, such as Figure 3 As shown, a nozzle 12 is installed on one side of the cutting machine 9 via a metal plate corresponding to the bottom position of the cutting blade. A Hall sensor 16 is fixedly connected to one side of the cutting machine 9. A rectangular magnet that cooperates with the Hall sensor 16 is provided on the outer side of the support plate 5. When the Hall sensor 16 moves downward to correspond with the magnet, the nozzle 12 blows out a cooling medium to cool the cutting blade of the cutting machine 9.

[0032] It should be noted that in this embodiment, the position of the magnet is adjusted according to the height of the top of the object being cut, so that when the cutting blade contacts the object, the Hall sensor 16 corresponds to the top of the rectangular magnet. The Hall sensor 16 transmits a signal to the controller, which controls the solenoid valve of the nozzle 12 to open. The solenoid valve is connected to high-pressure water or air to cool the cutting position. Because the magnet is rectangular, the Hall sensor 16 remains aligned with the magnet during the downward cutting process, allowing the nozzle 12 to work continuously during the cutting process. When the cutting machine 9 returns to its upward position, the solenoid valve closes, and the nozzle 12 stops working.

[0033] In one embodiment, such as Figure 3 As shown, the pushing unit also includes a linear module 17 fixedly connected to one side of the support frame 1, and the movable slide of the linear module 17 is fixedly connected to the vertical rod 18.

[0034] It should be noted that in this embodiment, a suitable positioning frustum 20 is selected according to the diameter of the rolled PVC electrostatic film. The position of the positioning frustum 20 above the horizontal bar 19 is adjusted according to the center position of the rolled PVC electrostatic film, and the height of the horizontal bar 19 on the vertical bar 18 is adjusted. In this way, the rolled PVC electrostatic film can be pushed forward a certain distance by the straight module 17, so that the segmented cutting thickness is the same.
