Description

Technical Field

[0001] The utility model relates to the technical field of slitting, in particular to a film slitting structure. Background Art

[0002] The laminating machine includes a film feeding device, a conveyor belt and a hot pressing device. The film feeding device can guide the film to one end of the conveyor belt feed. The raw material sheet material or paper product is conveyed on the surface of the conveyor belt. After the film and the raw material sheet material or paper product are bonded together, they enter the hot pressing mechanism and are pressed together to form a long laminated strip. After the laminated strip is guided out of the hot pressing mechanism, it needs to be cut.

[0003] Most of the existing laminating machine slitting mechanisms use ring knives for slitting, which has a fast slitting speed and good effect. However, in daily use, the tool must be stopped to replace. Since the tool installed on the mounting ring is long, more bolts are used, which makes its installation and disassembly time-consuming. This increases the time required for equipment downtime, affects the use of the slitting mechanism, and also reduces the laminating processing efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a film-cutting structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a film slitting structure, comprising a frame, a mounting frame fixedly installed on the top of the frame, two transverse moving components symmetrically installed on the mounting frame, and slides fixedly installed on the movable ends of the two transverse moving components; electric push rods are symmetrically fixedly installed on the tops of the two slides, and the movable ends of the two electric push rods on the same side are jointly fixedly installed with a movable frame, the inner surfaces of the two movable frames are rotatably connected to ring knives, and a drive assembly is jointly installed between the two movable frames and the adjacent ring knives.

[0006] Furthermore, both of the transverse movement assemblies include a handwheel, and the handwheel is arranged on one side of the bottom of the mounting frame. A worm is fixedly connected to the top center of the handwheel, and the worm extends through the bottom of the mounting frame to the interior and is rotatably connected thereto. The outer surface of the worm is meshed with a worm wheel. The setting of the handwheel is conducive to manually driving the transverse movement assembly to operate.

[0007] Furthermore, a screw rod passes through and is fixedly connected to the outer wall of one side of the worm wheel, and the screw rod is rotatably mounted on the inner walls on both sides of the mounting frame. A slider is threadedly sleeved on the outer surface of the screw rod, and the slider is fixedly connected to the slide plate. The rotation of the screw rod can drive the slider to move, thereby driving the slide plate to move.

[0008] Furthermore, the two ring cutters each include a cutter holder, and the cutter holder is rotatably connected to the movable frame. The cutter body is inserted on both sides of the outer surface of the cutter holder, and the cutter holder and the cutter body are fixedly connected with bolts. The cutter holder and the cutter body are fixed with bolts, which is conducive to the installation and disassembly of the cutter body and can also ensure the tightness of the connection.

[0009] Furthermore, the two driving components both include a motor, and the motor is fixedly mounted on the top of the movable frame. The driving end of the motor is fixedly connected to a small synchronous pulley, and a large synchronous pulley is provided below the small synchronous pulley. The mounting shaft of the large synchronous pulley passes through the movable frame and is fixedly connected to the knife seat. The small synchronous pulley and the large synchronous pulley are engaged with each other and are sleeved with a synchronous belt, which can drive the ring knife to rotate. The rotation speed matches the conveying speed of the material, which is beneficial to cutting the material after coating.

[0010] Furthermore, the inner walls on both sides of the frame are connected to a plurality of pressure rollers for rotation, which can ensure the stability of material movement.

[0011] Furthermore, sliding grooves are provided on both sides of the outer surface of the mounting frame, and the sliding grooves are slidingly connected to adjacent slides. One end of the sliding groove is connected to one end face of the mounting frame, so that the slide can be moved out of the mounting frame along the sliding groove, so that the slide can be located on one side of the frame, thereby driving the ring knife to move to one side of the frame, thereby facilitating the operation of the ring knife.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the film slitting structure adopts a double-station operation through the installation frame, transverse movement component, electric push rod, slide plate, movable frame, ring knife and drive component, so that the time used for changing the tool overlaps with the operating time of another ring knife, and then adopts gapless replacement, so that the slitting mechanism and the laminating machine do not need to stop operation when changing the tool, ensuring that the slitting mechanism and the laminating machine can be used continuously, thereby improving the laminating processing efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 4 As shown, it relates to a film cutting structure, including a frame 1, a mounting frame 5 is fixedly installed on the top of the frame 1, and two transverse moving components are symmetrically installed on the mounting frame 5, and a slide 6 is fixedly installed on the movable ends of the two transverse moving components. The two transverse moving components each include a handwheel 18, and the handwheel 18 is arranged on one side of the bottom of the mounting frame 5. A worm 16 is fixedly connected to the top center of the handwheel 18, and the worm 16 extends through the bottom of the mounting frame 5 to the inside and is rotatably connected thereto, and the outer surface of the worm 16 is meshed with a worm wheel 17, and one side outer wall of the worm wheel 17 passes through and is fixedly connected to a screw rod 14, and the screw rod 14 is rotatably installed on the inner walls on both sides of the mounting frame 5, and the outer surface of the screw rod 14 is threadedly sleeved with a slider 13, and the slider 13 is fixedly connected to the slide 6, and the worm wheel 17 and the worm 16 have self-locking properties. When the worm 16 does not rotate, the worm wheel 17 cannot drive the worm 16 to reverse.

[0023] Slide grooves 15 are provided on both sides of the outer surface of the mounting frame 5, and the slide grooves 15 are slidably connected to the adjacent slides 6. One end of the slide groove 15 is connected to one end surface of the mounting frame 5. The slide groove 15 has a limiting effect on the slide 6, which can ensure the stability of the movement of the slide 6. Since the slide 6 is fixedly connected to the slider 13, the stability of the movement of the slider 13 is ensured.

[0024] Electric push rods 7 are symmetrically fixed on the top of the two slides 6, and a movable frame 11 is fixedly installed on the movable ends of the two electric push rods 7 on the same side. The inner surfaces of the two movable frames 11 are rotatably connected with ring cutters. The two ring cutters include a knife seat 4, and the knife seat 4 is rotatably connected to the movable frame 11. The tool body 3 is inserted on both sides of the outer surface of the knife seat 4, and the knife seat 4 and the tool body 3 are fixed with bolts. The two electric push rods 7 drive the same movable frame 11 to move downward, which has a limiting effect on the movable frame 11 and can ensure the stability of the movement of the movable frame 11.

[0025] Both movable frames 11 are equipped with a driving assembly between adjacent ring cutters. Both driving assemblies include a motor 10, and the motor 10 is fixedly installed on the top of the movable frame 11. The driving end of the motor 10 is fixedly connected to a small synchronous pulley 8. A large synchronous pulley 12 is provided below the small synchronous pulley 8, and the mounting shaft of the large synchronous pulley 12 passes through the movable frame 11 and is fixedly connected to the knife seat 4. The small synchronous pulley 8 and the large synchronous pulley 12 are engaged with each other and are sleeved with a synchronous belt 9. The motor 10 drives the small synchronous pulley 8 to rotate, and the small synchronous pulley 8 drives the large synchronous pulley 12 to rotate through the synchronous belt 9, thereby driving the ring cutter to rotate.

[0026] The inner walls on both sides of the frame 1 are connected to a plurality of pressing rollers 2 for joint rotation. During slitting, the ring knife is located in the middle of the two pressing rollers 2, which is beneficial for conveying the slit materials.

[0027] Working principle: When the tool body 3 in use needs to be replaced, the handwheel 18 on the side of the unused tool holder 4 is rotated, and the handwheel 18 drives the worm gear 17 to rotate through the worm 16, and the worm gear 17 drives the screw rod 14 to rotate. The screw rod 14 drives the slide plate 6 along the slide groove 15 to the side of the frame 1 through the slider 13, and the slide plate 6 drives the movable frame 11 and the unused tool holder 4 to move to the side of the frame 1 through the electric push rod 7. Then the new tool body 3 is installed on the tool holder 4, thereby forming a ring knife, and then the unused ring knife is reset through the transverse movement component. Then the driving component on the side of the unused ring knife is operated, the motor 10 drives the small synchronous pulley 8 to rotate, and the small synchronous pulley 8 drives the large synchronous pulley 12 to rotate through the synchronous belt 9, thereby driving the ring knife to rotate. When the speeds of the two ring knives are consistent, the electric push rod 7 moves down to the set position through the movable frame 11, thereby driving the unused ring knife to move to the set position, so that the two ring knives start synchronous cutting, and then the electric push rod 7 on the other side drives the used ring knife to reset through various components, thereby completing the gapless replacement of the ring knife.
