Technical Field

[0001] This utility model belongs to the field of film pressing mechanism, specifically, it relates to a film pressing mechanism for reflective film. Background Technology

[0002] Reflective film is a pre-made thin film that can be directly applied as a retroreflective material. When printing on reflective film, a lamination mechanism is required to ensure the continuity of the printing process.

[0003] Patent application CN221272282U discloses a film pressing mechanism for reflective film. Paragraph 0031 of the specification discloses that: a supporting rod is rotatably connected between two support plates via bearings, and a roller is fixedly sleeved on the surface of the supporting rod. By setting the supporting rod and the roller, it is convenient to cooperate with the printing roller for printing work.

[0004] In actual use, when printing on the reflective film body using a printing roller, it is difficult to keep the reflective film body in the center of the printing roller, which can easily cause the printing of the reflective film body to become disordered.

[0005] To address these shortcomings, a lamination mechanism for reflective film is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a film pressing mechanism for reflective film, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A film pressing mechanism for reflective film includes a film pressing assembly and two guide assemblies;

[0009] The film pressing assembly includes two support plates, a roller is rotatably fitted between the two support plates, sliding blocks are slidably fitted on the support plates, and a printing roller is rotatably fitted between the two sliding blocks;

[0010] The guide assembly includes a guide block and two collars. A fixed plate is provided on the collar. The guide block is elastically fitted between the two fixed plates. A threaded rod is elastically fitted on the guide block. A guide seat is provided at one end of the threaded rod. A nut is threadedly fitted on the threaded rod and engages with the guide block.

[0011] Optionally, the support plate is provided with a guide groove and a first through hole, the sliding block is slidably fitted in the guide groove, the first through hole is located below the guide groove, a hydraulic cylinder is provided in the guide groove, the sliding block is fixedly connected to the output end of the hydraulic cylinder, and a base is provided between the two support plates.

[0012] Optionally, both ends of the roller are provided with a first rotating rod, one end of the first rotating rod is rotatably fitted in the first through hole, the sliding block is provided with a second through hole, both ends of the printing roller are provided with a second rotating rod, one end of the second rotating rod is rotatably fitted in the second through hole, the collar is provided with a connecting rod, the fixing plate is fixed on the connecting rod, and the fixing plate is provided with a guide hole.

[0013] Optionally, a guide rod is provided on the guide block, the guide rod is slidably fitted in the guide hole, a positioning plate is provided at the end of the guide rod away from the fixed plate, a first spring is provided between the guide block and the fixed plate, the first spring is sleeved on the guide rod, a third through hole is provided on the guide block, a threaded rod is slidably fitted in the third through hole, a sliding plate is provided at the end of the threaded rod away from the guide block, a second spring is provided between the sliding plate and the guide block, the second spring is sleeved on the threaded rod.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] The lamination mechanism of this reflective film body, through the elastic positioning structure of the guide assembly, ensures that the reflective film body remains in the central area of ​​the printing roller during the printing process, reducing printing disorder caused by positioning deviation. The guide block, through the elastic cooperation of the first spring and the fixed plate, combined with the buffer adjustment of the second spring on the threaded rod and the guide seat, can adapt to reflective film bodies of different widths by rotating the nut, and can also use the elastic compression of the first and second springs to correct the offset of the reflective film body in real time, improving the lamination and printing efficiency of the reflective film body by 30%.

[0016] The guide block is slidably fitted in the guide hole of the fixed plate through the guide rod. The first springs on both sides are sleeved on the guide rod to provide elastic support for the guide block. When the reflective film body is offset, the guide block is squeezed and drives the guide rod to slide in the guide hole. The elastic force of the first spring can push the guide block back in real time to keep it in the center. At the same time, the threaded rod is slidably fitted with the guide block through the third through hole. A second spring is set between the sliding plate at its end and the guide block to form an elastic buffer. When the width of the reflective film body changes or fluctuates during movement, the second spring can adjust the position of the guide seat by compression or extension to reduce the deformation of the reflective film body caused by compression.

[0017] The threaded nut on the threaded rod engages with the guide block. Rotating the nut adjusts the extension length of the threaded rod, thereby changing the position of the guide seat. Through this structure, the distance between the two guide seats can be manually adjusted according to the actual width of the reflective film body, so that the inner side of the guide seat is in close contact with the edge of the reflective film body, achieving limiting. For example, when dealing with reflective film bodies of different specifications, simply tightening the nut is enough for quick adaptation without replacing parts, improving the versatility of the equipment.

[0039] Working principle:

[0040] When the reflective film body is embossed, the hydraulic cylinder 5 drives the sliding block 6 to slide up and down in the guide groove 3, causing the printing roller 10 to move closer to or away from the roller 8, thus realizing the pressing and printing actions. When the reflective film passes between the roller 8 and the printing roller 10, the guide assembly plays a positioning role. The guide block 18 slides in the guide hole 15 of the fixed plate 14 through the guide rod 16. The first spring 19 provides elastic support to keep the guide block 18 in the center. The guide seat 22 on the threaded rod 25 is elastically engaged with the guide block 18 through the second spring 24. The rotating nut 23 can adjust the extension length of the threaded rod 25, thereby changing the position of the guide seat 22 to adapt to reflective film bodies of different widths. When the reflective film body moves, the guide seat 22 restricts its displacement through elastic compression. Combined with the buffering effect of the first spring 19, the reflective film body is always kept in the middle area of ​​the printing roller 10, reducing the printing disorder of the reflective film body.
