Description

Technical Field

[0001] This utility model relates to the technical field of film roll feeding devices, and more specifically, to a film roll feeding device. Background Technology

[0002] Lamination is a surface finishing process after printing. It refers to the technology of using a laminating machine to cover the surface of printed materials with a layer of transparent plastic film to form a paper-plastic composite product.

[0003] The film used in the laminating process is a cylindrical roll wound on a reel and loaded onto the roll rack of the laminating machine. The roll rack has two opposing end slots; the ends of the reel can be engaged into these slots to load the film. A new roll needs to be replaced after each use. Current technology typically uses mechanical equipment to handle the rolls, adjusting the equipment's height to align the rolls with the roll rack, and then manually loading the rolls onto the rack. However, because the end slots on the roll rack are small, each loading process takes a considerable amount of time, resulting in low film loading efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a film roll feeding device that enables rapid film roll feeding, shortens installation time, and improves feeding efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A film roll feeding device includes a base, with fixed plates at both ends of the upper surface of the base. Two longitudinally distributed mounting brackets are provided between the pair of fixed plates, and two transversely distributed mounting plates are provided between the two mounting brackets. A driving mechanism for driving the two mounting plates to move towards or away from each other is provided between the gaps between the two mounting brackets. A support rod is provided on the side of the two mounting plates facing each other. A feeding groove is opened on the side of the base, and the feeding groove is located between the pair of fixed plates.

[0027] Example 1

[0028] like Figures 1-4 As shown, this embodiment provides a film roll feeding device, including a base 1. The upper surface of the base 1 is provided with fixing plates 2 at both ends. Two longitudinally distributed mounting brackets 3 are provided between the pair of fixing plates 2. Two transversely distributed mounting plates 4 are provided between the two mounting brackets 3. The gap between the two mounting brackets 3 is provided with a driving mechanism for driving the two mounting plates 4 to move towards or away from each other. A support rod 5 is provided on the side of the two mounting plates 4 facing each other. A feeding groove 6 is opened on the side of the base 1. The feeding groove 6 is located between the pair of fixing plates 2. The groove cavity of the feeding groove 6 is provided with a lifting mechanism 7. The upper surface of the lifting mechanism 7 is provided with a feeding mechanism.

[0029] The film roll is placed on the working surface of the feeding mechanism, and the feeding mechanism 7 is lifted to simultaneously lift the film roll. When the film roll is lifted to a fixed position, the drive mechanism drives the mounting plates 4 to move towards each other, so that the support rods 5 on the opposite sides of the two mounting plates 4 are inserted into the film roll drum from both ends, realizing rapid installation of the film roll and improving film roll feeding efficiency. In addition, the drive mechanism, mounting plates 4 and support rods 5 can work together to realize the rapid installation of film rolls of different lengths, making it widely applicable.

[0030] In a specific embodiment, the driving mechanism includes a sliding groove 16 formed on one side of each of the two mounting brackets 3 facing each other, and a motor 10 mounted on the outside of a fixed plate 2. A double-ended screw 17 is provided in one sliding groove 16, and a guide rod 18 is provided in the other sliding groove 16. One end of the mounting plate 4 is threadedly connected to the double-ended screw 17, and the other end of the mounting plate 4 is movably connected to the guide rod 18. One end of the double-ended screw 17 passes through the fixed plate 2 and connects to the output end of the motor 10. The double-ended screw 17 and the guide rod 18 are connected to the inner wall of the sliding groove 16 via bearings. The mounting plate 4 has a through hole on one side of the guide rod 18, through which the guide rod 18 connects to the mounting plate 4. The motor 10 is connected to the double-ended screw 17 via a coupling. The motor 10 drives the double-ended screw 17 to rotate, synchronously driving the mounting plate 4 to move towards each other, bringing the two support rods 5 closer together. This allows the two support rods 5 to be inserted into the membrane roll from both ends, achieving rapid installation of the membrane roll.

[0031] In a specific embodiment, the feeding mechanism includes a support plate 8, with two support seats 9 on the upper surface of the support plate 8, and a support groove 19 formed on the top of each support seat 9. The support seats 9 and the support groove 19 are used to support the film roll to prevent it from moving on the support plate 8. The support plate 8 and the lifting mechanism 7 can be welded or connected by screws.

[0032] In a specific embodiment, the bearing groove 19 is V-shaped or arc-shaped.

[0033] In a specific embodiment, the support plate 8 has connecting holes 12 on both sides. A limiting plate 13 is movably installed in the connecting holes 12. The limiting plate 13 is L-shaped. The horizontal part of the limiting plate 13 is located inside the connecting hole 12 and connected to the end face of the connecting hole 13 by a spring 14. The vertical part of the limiting plate 13 is located outside the connecting hole 12. A stop block 15 is provided on the side of the vertical part of the limiting plate 13 facing the support seat 9. The limiting plate 13, the stop block 15 and the spring 14 cooperate to limit the film roll from both ends, preventing the film roll from slipping out of the support groove 19, and further improving the stability of the film roll during feeding.

[0034] In a specific embodiment, the inner wall of the bearing groove 19 is provided with a protective pad, and the abutment 15 is a rubber block. The protective pad and the rubber block can prevent the bearing groove 19 and the abutment 15 from damaging the film roll.

[0035] In a specific implementation, the lifting mechanism 7 is a scissor lift structure. The scissor lift structure is a scissor hydraulic lift.

[0036] In a specific embodiment, the bottom end of the lifting mechanism 7 is provided with an array of casters 11. The casters 11 enable the lifting mechanism 7 to move, so as to facilitate the lifting mechanism 7 in transporting the film roll.

[0037] The working principle of a film roll feeding device is as follows: The film roll is placed in the bearing groove 19 at the top of the bearing seat 9, and the abutment block 15 on the inner side of the limiting plate 13 abuts against both ends of the film roll. The lifting mechanism 7 drives the bearing plate 8 to rise, and simultaneously drives the bearing seat 9 to rise, so that the film roll at the top of the bearing seat 9 rises. When the film roll rises to the point that the central axis of the film roll coincides with the central axis of the support column 5, the lifting mechanism 7 stops rising. The motor 10 drives the double-headed screw 17 to rotate, so that the two mounting plates 4 on the double-headed screw 17 move towards each other, so that the two support columns 5 move closer to each other until the two support columns 5 are completely inserted into the film roll drum. The motor 10 stops moving, completing the rapid feeding and installation of the film roll.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
