Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment components, and particularly relates to a clutch pressure wheel structure of a film printing device. Background Art

[0002] In the process of plastic film production, operations such as printing words and patterns on the film are required to distinguish it from other plastic films.

[0003] During the printing process of the film, it is necessary to ensure that the printing wheel and the pressure wheel are pressed against each other for printing. However, due to films of different thicknesses, the distance between the roller of the clutch pressure wheel and the printing roller needs to be adjusted to successfully complete the printing work. Most printing equipment on the market lacks a corresponding adjustment structure. Therefore, it is necessary to replace the equipment for films of corresponding thicknesses to ensure successful printing, which requires purchasing corresponding mechanical equipment during the processing, undoubtedly greatly increasing the printing cost. Therefore, technical personnel in the field have provided a clutch pressure wheel structure of a film printing device to solve the problems raised in the above background art. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a clutch pressure wheel structure of a film printing device, which includes a pressure wheel frame plate. The left and right ends of the pressure wheel frame plate are symmetrically and fixedly installed with vertical support plates. Several pneumatic piston rod seats are fixedly installed at the upper end of the pressure wheel frame plate. The same bracket is installed on the upper ends of the pneumatic piston rod seats. A clutch pressure roller is sleeved on the bracket. A positioning seat plate is fixedly installed at the rear side of the upper end of the pressure wheel frame plate. A lifting component is fixedly installed at the front end of the positioning seat plate, and the lifting component can provide a lifting drive for the bracket.

[0005] The lifting component includes a folded plate, a limit sleeve seat, a threaded rod, a first helical gear, a driving rod, a second helical gear, and a servo motor. Two folded plates are fixedly installed in the middle of the front end face of the positioning seat plate. The two folded plates are symmetrically arranged left and right. The limit sleeve seat is fixedly installed at the upper end of the folded plate. A rotatable threaded rod is arranged in the limit sleeve seat. The lower end of the threaded rod passes through the folded plate and is fixedly installed with the first helical gear. The threaded rod and the first helical gear are both rotatably arranged on the folded plate. A rotatable driving rod is arranged between the two folded plates. The left and right ends of the driving rod pass through the folded plate and are fixedly installed with the second helical gear. The second helical gear is in meshing engagement with the first helical gear. The right end of the driving rod passes through the right vertical support plate and is fixedly connected to the output shaft of the servo motor. The servo motor is fixed on the right vertical support plate.

[0006] Preferably: A driving seat is fixedly installed at the lower part of the left end face of the vertical support plate. A driving system is fixedly installed at the upper end of the driving seat. A differential braking system is fixedly installed at the upper part of the left end face of the vertical support plate. A driving linkage structure is arranged between the differential braking system and the driving system.

[0007] Preferably, a printing roller is fixedly installed between the upper parts of the vertical plates of the bracket. The printing roller is drivingly connected to the differential braking system, so that the driving system drives the differential braking system through the driving linkage structure to rotate the printing roller and complete the printing work.

[0008] Preferably, limit members are symmetrically and fixedly installed at the left and right ends of the clutch pressure roller. A limit moving slot is formed in the middle of the inner end face of the vertical plate of the bracket, and the limit member can freely slide in the limit moving slot.

[0009] Preferably, the bracket includes a support plate seat, an arc-shaped support plate, a triangular seat frame, a collar and a female seat plate. Triangular seat frames are symmetrically and fixedly installed on the left and right sides of the upper end face of the support plate seat. A collar is fixedly installed at the upper end of the triangular seat frame and is used for sleeving the shaft end of the clutch pressure roller, so that the clutch pressure roller can be mounted in the air and rotate in reverse with the printing roller to print the film.

[0010] Preferably, an arc-shaped support plate is fixedly installed at the upper end of the support plate seat. The arc-shaped support plate can effectively lift the clutch pressure roller, so that after the clutch pressure roller is over-pressed and bent, it can be braked by friction with the arc-shaped support plate, thereby avoiding the formation of air pockets during the process of the clutch pressure roller and the printing roller cooperating to print the film, resulting in printing failure. Mother seat plates are symmetrically fixed on the left and right of the rear end face of the support plate seat, and the mother seat plates are meshed with the threaded rod.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. When the present utility model is used, the pneumatic live rod seat is extended and retracted by an external air source, and the pneumatic live rod seat abuts against the lower end of the support plate seat, thereby reducing the deviation of the pressure exerted on the film by the clutch pressure roller and the printing roller, ensuring a constant pressure on the film during the printing process, and ensuring good printing effects.

[0013] 2. When the present utility model is used, the driving servo motor drives the second helical gear on the driving rod to rotate. The second helical gear meshes with the first helical gear, and the first helical gear drives the threaded rod to mesh with the mother seat plate. The mother seat plate then drives the clutch pressure roller lifted on the support plate seat to rise and fall, and cooperates with the limit member to slide directionally in the limit moving slot, so that the process of the clutch pressure roller approaching the printing roller is stable, reducing the lifting height error during the lifting process, and adapting to the printing work of films with different thicknesses.
