Description

Technical Field

[0001] This utility model relates to the field of PVC film production and processing technology, and in particular to a PVC film edge cutting device. Background Technology

[0002] PVC film has gradually won people's favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. PVC material has the characteristics of being lightweight, heat-insulating, heat-preserving, moisture-proof, flame-retardant and easy to construct. It has a wide variety of specifications, colors and patterns, and is highly decorative. It can be used for a series of decorations such as interior walls, windows, floors and ceilings.

[0003] In the production process of PVC film, to ensure uniform width, it is necessary to use a cutting blade to trim the edges. However, during the trimming process, the cutting blade inevitably wears down. To ensure the trimming accuracy of the PVC film, the worn cutting blade needs to be replaced in a timely manner. If the worn cutting blade is continued to be used to trim the PVC film, it is easy to cause misalignment of the trimming edge, or even damage to the main body of the PVC film. In the existing technology, replacing the cutting blade is a cumbersome operation, with long downtime for replacement, which affects the efficiency of PVC film trimming. Furthermore, in the existing technology, the position adjustment of the two cutting blades must be done individually, resulting in low flexibility of the device. Therefore, this utility model proposes a PVC film trimming device to solve the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a PVC film cutting device. Two movable seats can be synchronously adjusted to cut standard-sized PVC films of different widths. The first and second drive rods, which are rotatably arranged in the mounting slots of the movable seats, can be synchronously rotated through pulleys and synchronous belts. Consequently, the first cutting blade on the first drive rod and the second cutting blade on the second drive rod can also be synchronously adjusted in angle, making the replacement of the cutting blades convenient and quick.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A PVC film edge-cutting device includes a mounting base, with two sets of mounting bases symmetrically arranged. A unwinding roller and a take-up roller are symmetrically and rotatably arranged between the two sets of mounting bases. A first transmission roller is symmetrically arranged between the unwinding roller and the take-up roller, and a second transmission roller is arranged between the two first transmission rollers. An edge-cutting blade position adjustment drive mechanism is provided between the two sets of mounting bases above the second transmission roller. A movable seat is symmetrically arranged on the edge-cutting blade position adjustment drive mechanism. A mounting groove is provided at the bottom of the movable seat. A first drive rod and a second drive rod are rotatably arranged within the mounting groove. A first blade holder is provided on the first drive rod, and a second blade holder is provided on the second drive rod. A first edge-cutting blade is provided on the first blade holder, and a second edge-cutting blade is provided on the second blade holder.

An edge-cutting blade switching and adjustment drive mechanism is provided on the outer wall of the movable seat, and the first drive rod is driven to rotate by the edge-cutting blade switching and adjustment drive mechanism.

[0006] A further improvement is that the installation height of the first drive roller is greater than the installation height of the unwinding roller and the winding roller, and the installation height of the second drive roller is greater than the installation height of the first drive roller.

[0007] A further improvement is that the cutting blade position adjustment drive mechanism includes a bidirectional lead screw, a guide rod, and a first knob. The bidirectional lead screw is rotatably provided between the two sets of mounting seats. A guide rod is provided below the bidirectional lead screw. A first knob is provided at one end of the bidirectional lead screw. The movable seat is threadedly connected to the bidirectional lead screw, and the movable seat is slidably connected to the guide rod.

[0008] A further improvement is that the cutting blade switching and adjustment drive mechanism includes a mounting plate, a worm gear, and a worm. Mounting plates are symmetrically arranged on one side wall of the movable seat. A worm gear is provided at one end of the first drive rod. A worm is rotatably arranged between the two mounting plates. A second knob is provided at one end of the worm, and the worm meshes with the worm gear.

[0009] A further improvement is that a recovery roller is rotatably mounted between the two sets of mounting seats above the take-up roller, and the rotation direction of the recovery roller is opposite to that of the take-up roller.

[0010] A further improvement is that a geared drive motor is provided on the outer wall of one set of mounting bases, and a second drive roller is provided between the first drive rollers, all of which are driven to rotate by the geared drive motor.

The two movable seats can synchronously adjust their positions to meet the requirements of cutting standard-sized PVC films of different widths. The first and second drive rods, which are rotatably arranged in the mounting groove of the movable seats, can be linked with the pulley and the timing belt to achieve synchronous rotation. Thus, the first cutting blade on the first drive rod and the second cutting blade on the second drive rod can also be synchronously adjusted in angle. When the first cutting blade wears out, by controlling the synchronous rotation of the first and second drive rods, the first cutting blade can be rotated out of the cutting position while the second cutting blade is rotated into the cutting position for cutting operations. This makes the replacement of the cutting blade convenient and fast. Attached Figure Description

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1-5As shown, this embodiment proposes a PVC film edge-cutting device, including a mounting base 1. Two sets of mounting bases 1 are symmetrically arranged. An unwinding roller 2 and a take-up roller 3 are symmetrically and rotatably arranged between the two sets of mounting bases 1. A first drive roller 4 is symmetrically arranged between the unwinding roller 2 and the take-up roller 3. A second drive roller 5 is arranged between the two first drive rollers 4. An edge-cutting blade position adjustment drive mechanism 6 is provided between the two sets of mounting bases above the second drive roller 5. A movable seat 7 is symmetrically arranged on the edge-cutting blade position adjustment drive mechanism 6. The bottom of the movable seat 7 is provided with a mounting groove 8. A first drive rod 9 and a second drive rod 10 are rotatably mounted inside the groove 8. The first drive rod 9 is equipped with a first cutter holder 11, and the second drive rod 10 is equipped with a second cutter holder 12. The first cutter holder 11 is equipped with a first edge-cutting cutter 13, and the second cutter holder 12 is equipped with a second edge-cutting cutter 14. One end of the first drive rod 9 and the second drive rod 10 is equipped with a pulley 15, and the two pulleys 15 are connected by a synchronous belt 16. The outer wall of the movable seat 7 is equipped with an edge-cutting cutter switching and adjustment drive mechanism, and the first drive rod 9 is driven to rotate by the edge-cutting cutter switching and adjustment drive mechanism.

[0016] In use, the PVC film edge-cutting device of this utility model unwinds the PVC film from the unwinding roller 2, drives the second drive roller 5 after passing through the first drive roller 4, and then passes through another set of first drive rollers 4. One end of the film is then connected to the take-up roller 3. When the PVC film begins to move, the first edge-cutting blade 13 on the first blade holder 11 cuts the edges of the PVC film to achieve edge trimming. When the first edge-cutting blade 13 needs to be replaced, the first drive rod 9 is rotated by the edge-cutting blade switching and adjustment drive mechanism. When the first drive rod 9 rotates, the second drive rod 10 rotates synchronously under the transmission of the pulley 15 and the synchronous belt 16. The first cutting blade 13 is flipped upwards and detached from the PVC film by rotating counterclockwise. At this time, the second cutting blade 14 contacts the PVC film by flipping, thus achieving edge cutting. In this utility model, the first cutting blade 13 and the second cutting blade 14 are detachably installed with the first blade holder 11 and the second blade holder 12, respectively. When the first cutting blade 13 is detached from the PVC film, it can be removed and replaced. When the second cutting blade 14 is worn and needs to be replaced, the first drive rod 9 is rotated in the reverse direction, so that the second cutting blade 14 is detached from the PVC film. The replaced first cutting blade 13 contacts the PVC film, thus achieving edge cutting.

[0017] The installation height of the first drive roller 4 is greater than the installation height of the unwinding roller 2 and the winding roller 3, and the installation height of the second drive roller 5 is greater than the installation height of the first drive roller 4.

[0018] The cutting blade position adjustment drive mechanism 6 includes a bidirectional lead screw 601, a guide rod 602, and a first knob 603. The bidirectional lead screw 601 is rotatably mounted between the two sets of mounting seats 1. The guide rod 602 is located below the bidirectional lead screw 601. The first knob 603 is located at one end of the bidirectional lead screw 601. The movable seat 7 is threadedly connected to the bidirectional lead screw 601 and slidably connected to the guide rod 602. In this invention, the positions of the two movable seats 7 can be quickly and synchronously adjusted, enabling the two sets of first cutting blades 13 and two sets of second cutting blades 14 to cut PVC films of different standard widths. Specifically, rotating the first knob 603 drives the bidirectional lead screw 601 to rotate, causing the two movable seats 7 to move synchronously relative to each other on the bidirectional lead screw 601 and the guide rod 602, thus achieving position adjustment.

[0019] The cutting blade switching and adjustment drive mechanism includes a mounting plate 17, a worm gear 18, and a worm 19. Mounting plates 17 are symmetrically arranged on one side wall of the movable seat 7. A worm gear 18 is provided at one end of the first drive rod 9. A worm 19 is rotatably arranged between the two mounting plates 17. A second knob 20 is provided at one end of the worm 19, and the worm 19 meshes with the worm gear 18. When the first drive rod 9 is driven to rotate, the second knob 20 drives the worm 19 to rotate. Then, the worm 19 drives the first drive rod 9, which is equipped with the worm gear 18, to rotate. Finally, under the transmission of the pulley 15 and the synchronous belt 16, the second drive rod 10 rotates synchronously.

[0020] A recovery roller 21 is rotatably mounted between the two sets of mounting seats 1 above the take-up roller 3. The rotation direction of the recovery roller 21 is opposite to that of the take-up roller 3. By setting the recovery roller 21, the scrap material generated from the cutting edge can be wound up and recycled.

[0021] A set of mounting bases 1 are provided with a speed reduction drive motor 22 on the outer wall, and a second drive roller 5 is provided between the first drive rollers 4, all of which are driven to rotate by the speed reduction drive motor 22.

[0022] This invention utilizes two symmetrically arranged movable seats 7 on the cutting blade position adjustment drive mechanism 6. The two movable seats 7 can synchronously adjust their positions to meet the requirements of cutting standard-sized PVC films of different widths. The first drive rod 9 and the second drive rod 10, which are rotatably arranged in the mounting groove 8 of the movable seats 7, can be linked with the timing belt 16 through the pulley 15 to achieve synchronous rotation. Consequently, the first cutting blade 13 located on the first drive rod 9 and the second cutting blade 14 located on the second drive rod 10 can also be synchronously adjusted in angle. When the first cutting blade 13 wears out, by controlling the synchronous rotation of the first drive rod 9 and the second drive rod 10, the first cutting blade 13 can be rotated out of the cutting position while the second cutting blade 14 is rotated into the cutting position for cutting operations. This makes the replacement of the cutting blade convenient and quick.
