Description

Technical Field

[0001] This utility model relates to the technical field of solventless laminating machines, specifically a solventless laminating machine that facilitates roll changing. Background Technology

[0002] Solvent-free laminating machines are production equipment that uses solvent-free adhesives to bond two or more substrates together. As core equipment in packaging printing and flexible packaging production, solvent-free laminating machines are widely used in food packaging, pharmaceutical packaging, and daily chemical product packaging due to their advantages such as eliminating the need for organic solvents, environmental friendliness, high lamination efficiency, and stable film adhesion strength. During the production of composite films using solvent-free laminating machines, the winding and changing process is a crucial node in the production flow, and its efficiency and convenience directly affect the overall production progress.

[0003] In existing technologies, most traditional solventless laminating machines adopt a single-station winding structure. After the winding roller finishes winding the composite film, the machine needs to be stopped to disassemble the full roll, install the empty roll, and readjust and reposition. The entire roll change process is time-consuming and reduces work efficiency. Some solventless laminating machines adopt a dual-station design, which can meet the basic requirement of improving work efficiency. However, after the roll change is completed, the overall weight of the winding roller with the composite film is relatively heavy. Workers need to lift and move the winding roller with the composite film to a designated location (such as the next station). The operation process is cumbersome, requires multiple people to cooperate, and has extremely high labor intensity. If the lifting operation is incorrect, it can easily cause accidents such as equipment collisions or personnel injuries, resulting in low safety. Therefore, we propose a solventless laminating machine that facilitates roll change to solve the above problems. Utility Model Content

[0028] 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.

[0029] like Figure 1-5As shown, this utility model provides a technical solution: a solventless laminating machine that facilitates roll changing, comprising a solventless laminating machine body 1, a base 2 fixedly installed on the bottom right side of the solventless laminating machine body 1, two symmetrically arranged upright plates 3 fixedly installed on the top of the base 2, a common rotating shaft 4 rotatably mounted between the two upright plates 3, two sets of symmetrically distributed roll changing brackets 5 arranged on the circumferential side of the rotating shaft 4, and take-up rollers 6 detachably installed and fixed on both sets of roll changing brackets 5, the take-up rollers 6 being used to take up the composite film produced by the solventless laminating machine body 1, and a fixedly installed on the rear side wall of the rear upright plate 3. Motor 7, whose output shaft is fixedly connected to the rear end of rotating shaft 4, is a reversible motor. Motor 7 drives rotating shaft 4, causing the two sets of roll-changing brackets 5 to rotate with shaft 4. This allows for interchangeable adjustments of the roll-changing brackets 5. Alternating use of the two sets of roll-changing brackets 5 facilitates the removal and installation of empty rolls 6 after the composite film has been wound. Once one roll 6 has finished winding, it can be immediately switched to another pre-installed empty roll 6 to continue operation, significantly reducing the time and effort required for manual removal and installation of rolls 6 during roll-changing. This design shortens down time and improves work efficiency. The roll changing bracket 5 includes a U-shaped plate 51, an electric telescopic rod 52, an adapter 53, an electric telescopic rod 54, a motor 55, and two rectangular plugs 56. The U-shaped plate 51 is fixedly installed on the circumferential side of the rotating shaft 4. The electric telescopic rod 52 is fixedly installed on the front outer wall of the U-shaped plate 51. The adapter 53 is rotatably installed on the output shaft end of the electric telescopic rod 52. The electric telescopic rod 54 is located on the rear side of the U-shaped plate 51. The motor 55 is fixedly installed on the output shaft end of the electric telescopic rod 54. The two rectangular plugs 56 are respectively fixedly installed on one end of the adapter 53 and the other end of the motor. Rectangular slots 61 are provided at both ends of the output shaft of motor 2 55 and the winding roller 6. Two rectangular plugs 56 are slidably installed in the corresponding rectangular slots 61. By using the sliding engagement of the two rectangular plugs 56 with the corresponding rectangular slots 61, the winding roller 6 can be securely clamped and fixed. Motor 2 55 is used to control the rotation of the clamped and fixed winding roller 6 so as to wind up the composite film produced by the solventless laminating machine body 1. The electric telescopic rod 1 52 and electric telescopic rod 2 54 can be used to control the horizontal linear movement of the corresponding rectangular plugs 56, thereby facilitating the quick assembly and disassembly of the winding roller 6.

[0030] In this embodiment, mounting holes are provided on both upright plates 3, and two bearings are fixedly sleeved on the rotating shaft 4. The outer rings of the two bearings are fixedly connected to the inner walls of the corresponding mounting holes to ensure smooth rotation of the rotating shaft 4.

[0031] In this embodiment, two symmetrically arranged L-shaped support rods 57 are fixedly installed on the rear outer wall of the U-shaped plate 51. The ends of the two L-shaped support rods 57 that are close to each other are fixedly connected to the outer wall of the electric telescopic rod 54. The design of the two L-shaped support rods 57 can provide stable support for the electric telescopic rod 54.

[0032] In this embodiment, a first clearance hole 58 is provided on the rear side wall of the U-shaped plate 51. The output shaft end of the second electric telescopic rod 54 passes through the first clearance hole 58. The diameter of the first clearance hole 58 is larger than the diameter of the second motor 55. The design of the first clearance hole ensures that the output shaft end of the second electric telescopic rod 54 can extend and retract smoothly. By designing the diameter of the first clearance hole 58 to be larger than the diameter of the second motor 55, it can be ensured that the second motor 55 will not collide with the U-shaped plate 51. A second clearance hole is provided on the front side wall of the U-shaped plate 51. The output shaft end of the first electric telescopic rod 52 passes through the second clearance hole. The design of the second clearance hole ensures that the output shaft end of the first electric telescopic rod 52 can extend and retract smoothly.

[0033] In this embodiment, a horizontal groove 8 is provided on the top of the base 2, located on the right side of the upright plate 3. A movable seat 10 is slidably installed in the horizontal groove 8. The top of the movable seat 10 extends outside the horizontal groove 8 and is fixedly installed with a hydraulic cylinder 11. An arc-shaped support plate 12 is fixedly installed at the output shaft end of the hydraulic cylinder 11. The hydraulic cylinder 11 can control the vertical lifting and lowering of the arc-shaped support plate 12. The arc-shaped support plate 12 is used to support the winding roller 6 of the wound composite film. A drive assembly is provided on the base 2. The drive assembly is used to control the horizontal linear movement of the movable seat 10. The drive assembly includes a lead screw 9 and a motor 13. The lead screw 9 is rotatably installed in the horizontal groove 8. The movable seat 10 is threaded onto the lead screw 9. Motor 13 is fixedly installed on the right side wall of base 2. The output shaft of motor 13 extends into the transverse groove 8 and is fixedly connected to the right end of lead screw 9. Motor 13 is a reversible motor. Motor 13 is used to drive lead screw 9 to rotate. By using the threaded connection between lead screw 9 and moving seat 10, the moving seat 10 can be controlled to move horizontally and linearly along the transverse groove 8. This can transfer the winding roller 6 of the composite film to the designated position, effectively replacing the manual lifting and transfer of the winding roller 6 of the composite film, greatly reducing the amount of manual labor, and avoiding potential safety hazards during manual lifting (such as the winding roller 6 slipping and personnel injury).

[0034] In this embodiment, a horizontal guide rod 14 is fixedly installed inside the horizontal groove 8, and the movable seat 10 is slidably sleeved on the horizontal guide rod 14. The design of the horizontal guide rod 14 ensures the stability of the movable seat 10 when it moves.

[0035] In this embodiment, an auxiliary bonding mechanism 15 is provided on the top right side of the solventless laminating machine body 1. The auxiliary bonding mechanism 15 is used to assist in pressing and bonding the composite film onto the winding roller 6. The auxiliary bonding mechanism 15 includes a crossbeam 151, an electric telescopic rod 152, a lifting plate 153, three vertical guide rods 154, a U-shaped beam frame 155, a pressing roller 156, three top blocks 157, and three springs 158. The crossbeam 151 is fixedly installed on the top of the solventless laminating machine body 1, and the electric telescopic rod 152 is fixedly installed on the right end of the crossbeam 151. Figure 1 , Figure 2 and Figure 5 As shown, the electric telescopic rod 152 is in the extended state. The lifting plate 153 is fixedly installed on the output shaft end of the electric telescopic rod 152. The top of the lifting plate 153 has three vertical holes distributed at equal intervals. The bottom ends of the three vertical guide rods 154 slide through the corresponding vertical holes. The bottom ends of the three vertical guide rods 154 are fixedly installed on the U-shaped beam 155. The pressing roller 156 is rotatably installed inside the U-shaped beam 155. The pressing roller 156 is located directly above the take-up roller 6 on the left side. The three top blocks 157 are fixedly installed on the top ends of the corresponding vertical guide rods 154. The three springs 158 are all fixedly installed on the top of the lifting plate 153. The top ends of the three springs 158 are respectively connected to the top blocks 154. The bottom of 57 is fixedly connected, and three springs 158 are respectively sleeved on the corresponding vertical guide rods 154. Utilizing the elastic force of the springs 158, as more and more composite film is wound on the left-side take-up roller 6, it can ensure that the pressing roller 156 adaptively adheres to the top surface of the composite film. This can effectively eliminate air bubbles formed between composite films due to residual air during the winding process, avoid wrinkles and misalignment of the wound composite film, and significantly improve the flatness and tightness of the wound composite film. The outer surface of the pressing roller 156 has a smooth surface structure, which can ensure the tight adhesion effect during the winding of the composite film while avoiding physical damage such as scratches and indentations to the surface of the composite film.

[0036] In this embodiment, motor 7, motor 55, motor 13, electric telescopic rod 52, electric telescopic rod 54, electric telescopic rod 152 and hydraulic cylinder 11 can all be purchased on the market. Their wiring connection method and control method are mature technologies in this field and have been fully disclosed. Therefore, they will not be described in detail here.

[0037] With the above structure, the solventless laminating machine provided by this utility model, which facilitates roll changing, allows for easy operation by placing an empty take-up roller 6 between the two rectangular plugs 56 on the left side (near the main body 1 of the solventless laminating machine). Then, the electric telescopic rods 52 and 54 on the left side are activated to extend, causing the two rectangular plugs 56 to be inserted into the rectangular slots 61 at both ends of the take-up roller 6, thus securing the take-up roller 6 firmly. One end of the laminated film produced by the solventless laminating machine main body 1 is then attached with tape or similar adhesive. The film is pasted and fixed onto the take-up roller 6. Then, the electric telescopic rod 152 is extended and operated. The output shaft of the electric telescopic rod 152 pushes the lifting plate 153 to descend vertically, which in turn drives the vertical guide rod 154, U-shaped beam 155 and pressing roller 156 to descend synchronously until the outer surface of the pressing roller 156 lightly contacts the upper surface of the starting end of the composite film on the take-up roller 6. Then, the electric telescopic rod 152 is stopped, and the motor 55 on the left side is controlled to run. The take-up roller 6 is rotated through the rectangular plug 56, and the produced composite film can be started to be wound up.

[0038] During the winding process, as more and more composite film is wound onto the winding roller 6, the thickness of the wound composite film gradually increases. The overall diameter of the winding roller 6 and the composite film increases synchronously, generating an upward pushing force on the pressing roller 156. This pushing force is transmitted to the vertical guide rod 154 through the U-shaped beam frame 155, pushing the vertical guide rod 154 to slide upward along the vertical hole on the lifting plate 153. At the same time, it drives the top block 157 at the top to stretch the spring 158, causing the spring 158 to undergo elastic deformation and store elastic force. The elastic force of the spring 158 acts in the opposite direction on the top block 157, and is transmitted to the pressing roller 156 through the vertical guide rod 154 and the U-shaped beam frame 155. This allows the pressing roller 156 to adaptively maintain a tight fit with the uppermost surface of the composite film, effectively eliminating air bubbles formed between the composite films due to air residue during the winding process, and significantly improving the flatness and compactness of the wound composite film.

[0039] Meanwhile, during the winding process, take another empty winding roller 6 and place it between the two rectangular plugs 56 on the right side (away from the solventless laminating machine body 1) between the U-shaped plates 51. Following the above operating steps, the winding roller 6 can be securely clamped and fixed. After the winding roller 6 is fixed, it can be used as a spare.

[0040] After the left-side take-up roller 6 finishes winding, stop the left-side motor 2 55. Then, use scissors or other tools to cut the composite film. Next, control the electric telescopic rod 3 152 to retract and reset. The output shaft of the electric telescopic rod 3 152 drives the lifting plate 153 to rise vertically, which in turn drives the vertical guide rod 154, U-shaped beam 155, and pressing roller 156 to rise synchronously. At this time, the pressing roller 156 moves upward and no longer contacts the composite film. Under the elastic force of the spring 158, the U-shaped beam 155 drives the pressing roller and the three vertical guide rods 154. Reset the circuit and then control motor 7 to run. The output shaft of motor 7 drives the rotating shaft 4 to rotate, causing the two sets of roll-changing brackets 5 to rotate with the rotating shaft 4. After swapping the positions of the take-up roller 6 that has wound up the composite film and the spare take-up roller 6, stop motor 7. Then, use tape or other adhesive to attach and fix one end of the composite film to the spare take-up roller 6 in the swapped position. By controlling the corresponding motor 55, the composite film can continue to be wound up following the above steps. At this time, control motor 13 to run, and motor 13 drives the lead screw 9 to rotate. By utilizing the threaded connection between the lead screw 9 and the movable seat 10, the movable seat 10 can be controlled to drive the hydraulic cylinder 11 and the arc-shaped support plate 12 to move horizontally to the left. When the arc-shaped support plate 12 moves directly below the winding roller 6 with the composite film wound up, the motor 13 stops running. Then, the hydraulic cylinder 11 is controlled to extend, pushing the arc-shaped support plate 12 upward until it contacts the composite film wound up on the winding roller. Then, the corresponding electric telescopic rods 52 and 54 are controlled to retract and reset, causing the rectangular plug 56 to be pulled out of the rectangular slot 61 of the winding roller 6, releasing the tension. For fixing the take-up roller 6, the arc-shaped support plate 12 can stably support the take-up roller 6 with the composite film wound up. Then, control the motor 3 13 to run in reverse. The motor 3 13 drives the lead screw 9 to rotate in reverse, which can control the moving seat 10 to drive the hydraulic cylinder 11, the arc-shaped support plate 12, and the take-up roller 6 with the composite film wound up to move horizontally to the right. This can transfer the take-up roller 6 with the composite film wound up to the designated position. At the same time, take another empty take-up roller 6 and clamp it according to the above operation steps. It can continue to be used as a spare, so that it can wait for the next roll change and transfer.
