Description

Technical Field

[0001] The invention relates to the technical field of laminating equipment, and in particular to a laminating processing device for a sign board. Background Art

[0002] In order to meet the needs of nighttime visibility, cylindrical light box signboards usually have a high-reflectivity adhesive reflective film attached to the concave surface of the inner wall and the surrounding area. The traditional film application method is to rotate the cylinder, use the film application roller to horizontally push the reflective film along the axis of the cylinder and attach it to the inner wall. However, due to the outward protruding structure inside the cylinder, the curvature of its surface makes it impossible for the traditional film application method to effectively cover it. Therefore, it is necessary to manually cut out the defective area, re-cut, position, and attach the reflective film, which is a cumbersome and time-consuming process, which significantly reduces production efficiency. For this reason, we propose a film application device for signboards. Summary of the invention

[0018] 1. The first push ring and the second push ring on the active disc push the passive wheel on the swing rod in turn, causing the swing rod to produce a periodic lifting motion, driving the coated ball to adaptively adjust the height along the convex surface of the inner wall of the cylinder, ensuring that the reflective film fits tightly to the complex curvature area without manual cutting and correction.

[0019] 2. The frame slides laterally on the column through the slide rod and the spring, and the ball head at the end of the connecting rod (31) slides against the side of the active disc. The synergistic effect of the extension ring further controls the lateral displacement of the frame. While the coating ball is lifted longitudinally, the lateral sliding mechanism drives it to move evenly along the axis of the cylinder to cover the entire inner wall area, avoiding coating interruption or dislocation caused by the protruding structure.

Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0028] Refer to the attached Figure 1-4 A device for laminating a signboard is provided, which is installed on a platform through a front block 11, a rear block 12, and a column 13. A driving motor is also installed on the platform. The front block 11, the rear block 12, and the column 13 are on the same straight line. A disc driving member 2 is connected between the front block 11 and the rear block 12 through a rotating shaft 25 so that it can rotate. A pulley 26 is sleeved on the rotating shaft 25 so that it is sleeved with the output end of the driving motor through a conveyor belt to realize the motor driving its rotation.

[0029] Refer to the attached Figure 1-2A through slot is transversely provided on the column 13, and a limit horizontal bar extending toward the center of the through slot is connected to the inner side of the through slot. A slide bar 14 is slidably provided in the through slot, and a groove corresponding to the horizontal bar is provided on the slide bar 14, so that the swing rod 4 slides transversely on the column 13;

[0030] Reference Figure 5-6 The end of the slide bar 14 away from the column 13 is also connected to the frame 3, the frame 3 extends to the front block 11 and is also connected to a transmission rod 33 at the extended end of the frame 3, the transmission rod 33 extends into the through hole on the front block 11, when the slide bar 14 slides in the column 13, it drives the transmission rod 33 on the frame 3 to slide in the through hole on the front block 11;

[0031] In order to facilitate the frame body 3 to be able to reset during this stroke, a spring 15 is sleeved on the slide rod 14 , one end of the spring 15 abuts against the column 13 , and the other end abuts against the frame body 3 .

[0032] A swing rod 4 is hinged on the frame 3, and the movable end of the swing rod 4 extends in the direction of the front block 11, and a passive wheel 43 is connected to the end of the swing rod 4 close to the front block 11, and an extension rod 41 is connected to the same end side of the swing rod 4, and the extension rod 41 extends in the direction of the front block 11 and continues to extend forward beyond the front block 11, and a coating ball 42 is also arranged on the extension end of the extension rod 41, and the coating ball 42 is used to cover the reflective film on the inner wall of the cylindrical sign;

[0033] In order to control the movement of the swing rod 4, a disc driving member 2 is arranged between the front block 11 and the rear block 12. The disc driving member 2 includes an active disc 21. A first push ring 22 is arranged on the outer arc surface of the active disc 21. The first push ring 22 is extended away from the axis of the active disc 21, and the connection between the active disc 21 and the first push ring 22 is smoothly transitioned, so that the passive wheel 43 connected to the swing rod 4 can be steadily lifted when rolling on the active disc 21. The first push ring 22 extends to one side of the front block 11 to provide space for the passive wheel 43 to slide laterally. A second push ring 23 is further provided on the side arc surface, and the second push ring 23 is located at the middle position of the first push ring 22. The connecting ends of the first push ring 22 and the second push ring 23 have a smooth transition. Before the active disc 21 rotates, the passive wheel 43 on the swing rod 4 abuts against the active disc 21. When the active disc 21 rotates, the passive wheel 43 rotates with it and contacts with the first push ring 22 first. Since the first push ring 22 is outward, the passive wheel 43 will be pushed upward. The active disc 21 continues to rotate, and the passive wheel 43 will contact with the second push ring 23 to be further pushed upward.

[0034] The disc drive member 2 also includes an extension ring 24 connected to the edge of one side of the active disc 21, the extension ring 24 extends in the direction of the front stop 11, the first push ring 22, the second push ring 23, and the extension ring 24 are partially covered, and the cross section of the extension ring 24 smoothly transitions with one side of the active disc 21, and the smooth transition point of the extension ring 24 is located between the smooth transition points of the first push ring 22 and the second push ring 23, that is, the starting point of the extension ring 24 is located in the middle of the travel of the first push ring 22 and the second push ring 23, and the extension ring 24 is located in the frame. 3 is also connected to a connecting rod 31, which extends away from the direction of the front stop 11 toward the active disc 21, and is connected to a ball head 32 at the extended end of the connecting rod 31 to form a sliding abutment with the side of the active disc 21. In other words, the movement trajectory of the coated ball 42 is initially lifted by the first push ring 22, and then the extension ring 24 is assisted by the ball head 32 to control the lateral sliding of the frame 3, and finally the second push ring 23 is lifted again, and the cylindrical identification plate is rotated at the same time, so that the inner wall of the cylinder protruding outward can be coated, eliminating the need for workers to operate.
