Description

Technical Field

[0001] This application relates to the technical field of thin-film printing, and more particularly to a cast film printing machine. Background Art

[0002] Modern printing machines generally consist of mechanisms such as plate loading, inking, imprinting, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into printing plates and installed on the printing machine. Then, ink is applied to the areas with text and images on the printing plate by manual or the printing machine, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate.

[0003] According to different production requirements, various patterns need to be printed on the film. However, the film is prone to offset during printing, which affects the printing quality. Therefore, a cast film printing machine is needed to solve the above problems. Summary of the Utility Model

[0004] The cast film printing machine proposed in this application aims to solve the problem that the film is prone to offset during printing and affects the printing quality as mentioned in the above background art.

[0005] To achieve the above objective, this application adopts the following technical solutions:

[0006] The cast film printing machine includes a workbench. A fixed frame, two vertical plates, and a mounting plate are installed at the top of the workbench. The fixed frame and the mounting plate are both located between the two vertical plates. A roller is rotatably arranged inside the fixed frame. A motor is installed on the front wall of the fixed frame. The output shaft of the motor passes through the fixed frame and is fixedly connected to the roller. A fixed plate and a connecting plate are fixedly arranged on the side of the mounting plate facing the fixed frame. The connecting plate is located below the fixed plate. A second electric push rod passes through the fixed plate. The end face of the output shaft of the second electric push rod is fixedly provided with a pressing plate. A cross beam is fixedly arranged between the two vertical plates. A first electric push rod is installed at the bottom end of the cross beam. The end face of the output shaft of the first electric push rod is fixedly provided with a printing plate.

[0007] By adopting the above technical solutions, the output shaft of the motor drives the roller to rotate, and the film on the roller can be pulled out, eliminating the need for manual pulling of the film by personnel and minimizing the risk of film damage. The second electric push rod can push the pressing plate downward to clamp one side of the pulled-out film between the pressing plate and the connecting plate, which can straighten the film and prevent the film from offsetting under the pressure of the printing plate during printing, thus improving the overall printing quality.

[0008] As a preferred embodiment, a fixing cylinder is fixedly provided on the top of the workbench, and the fixing cylinder is located below the mounting plate. An adjusting rod is slidably provided inside the fixing cylinder, and a screw is threadedly passed through the fixing cylinder, and the screw is in contact with the adjusting rod, and the top end of the adjusting rod is fixedly connected to the bottom end of the mounting plate.

[0009] By adopting the above technical solution, the height of the mounting plate can be adjusted by sliding the adjusting rod on the fixed cylinder. After the adjustment is completed, the adjusting rod is locked by the screw to keep the film on one side of the mounting plate and the film on one side of the roller at the same height, thereby avoiding damage to the film due to unevenness when the printing plate prints the film.

[0010] As a preferred embodiment, a third electric push rod is installed inside the workbench, and the output shaft of the third electric push rod passes through the outside of the workbench and is fixedly connected to a supporting platform. The supporting platform is located between the fixing frame and the mounting plate, and the printing plate is located above the supporting platform.

[0011] By adopting the above technical solution, the third electric push rod can push the supporting platform to rise and fall, and the supporting platform can support the bottom end of the film to avoid the bottom end of the film from being suspended in the air as much as possible, thereby playing the role of protecting the film to prevent the film from being damaged under the pressure of the printing plate.

[0012] As a preferred implementation, reinforcement frames are fixedly connected to both sides of the first electric push rod, screws are passed through the reinforcement frames, and the screws are threadedly connected to the crossbeam.

[0013] By adopting the above technical solution, the firmness of the installation of the first electric push rod can be improved under the action of the reinforcement frame and the screws.

[0014] As a preferred implementation, rubber pads are fixed to opposite sides of the pressure plate connecting plate by gluing.

[0015] By adopting the above technical solution, the rubber pad can avoid damaging the film when the pressure plate and the connecting plate clamp the film as much as possible.

[0016] As a preferred embodiment, four support columns are fixedly provided at the bottom end of the workbench, and the four support columns are respectively located at the four corners of the workbench.

[0017] By adopting the above technical solution, the workbench can be stably supported.

[0018] As a preferred implementation, the fixing tube is a hollow cylindrical structure, and the aperture of the fixing tube is matched with the diameter of the adjusting rod.

[0019] By adopting the above technical solution, the gap between the fixed cylinder and the adjusting rod can be reduced, and the stability of the adjusting rod can be improved.

[0020] As a preferred embodiment, the vertical cross-section of the roller is an H-shaped structure.

[0021] By adopting the above technical solution, the phenomenon of film deviation and shedding can be reduced.

[0022] Advantages of the present application:

[0023] 1. The output shaft of the motor drives the roller to rotate, so that the film on the roller can be taken out. There is no need for manual pulling of the film by personnel, and the damage to the film can be avoided as much as possible. The second electric push rod can push the pressing plate downward to clamp one side of the taken-out film between the pressing plate and the connecting plate, which can straighten the film and avoid the film from shifting under the pressure of the printing plate during printing, improving the overall quality of printing;

[0024] 2. By sliding the adjusting rod on the fixed cylinder, the height of the mounting plate can be adjusted. After the adjustment is completed, the adjusting rod is locked by the screw, so that the film on one side of the mounting plate is at the same height as the film on one side of the roller, avoiding the damage to the film caused by uneven height when the printing plate prints the film as much as possible.
