Description

Technical Field

[0001] The utility model relates to the field of printing equipment, and particularly to a positioning holographic image optical imprinting machine. Background Art

[0002] At present, a Chinese patent with the authorization announcement number CN214164373U discloses a film press for laser film production, which includes a box body, an upper pressing roller, tooth grooves, and a lower pressing roller. An upper pressing roller is arranged between the inner walls of the box body, and the upper pressing roller is rotationally connected to the box body. Tooth grooves are formed on the outer walls at both ends of the upper pressing roller. A lower pressing roller is arranged below the upper pressing roller, and the lower pressing roller is rotationally connected to the box body. Tooth keys are formed on the outer walls at both ends of the lower pressing roller. The tooth grooves are engaged with the tooth keys. A motor is arranged on one side wall of the box body, and the motor is connected to the box body by screws.

[0003] By setting the tooth grooves and the tooth keys, and the two are engaged. During the working process of the device, the upper pressing roller drives the lower pressing roller to rotate through the tooth grooves and the tooth keys. At the same time, the rotation directions of the upper pressing roller and the lower pressing roller are opposite, so as to flatten the wrinkled parts of the laser film in opposite directions, ensure the film pressing effect of the device, and improve the practicability of the device.

[0004] For a specific transparent film, a certain temperature range must be maintained to improve the quality of the transparent film during the embossing process. For example, in winter, the temperature of the transparent film needs to be increased, and in summer, the temperature of the transparent film needs to be decreased. This kind of film press obviously does not have this function, so its practicability is not high. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a positioning holographic image optical imprinting machine to achieve the purpose of improving practicability.

[0006] To solve the above technical problems, the technical solution of the utility model is: a positioning holographic image optical imprinting machine, including a main machine. A feeding roller, a winding roller, and a laser roller are rotationally connected to the main machine. An oil guide hole is axially formed in the laser roller. One end of the oil guide hole is rotationally connected to an oil injection pipe, and the other end of the oil guide hole is rotationally connected to an oil outlet pipe. A support frame is hinged to the main machine. A cooling pipe and a pressing roller are rotationally connected to the support frame. The cooling pipe abuts against the pressing roller. The two ends of the cooling pipe are respectively rotationally connected to a first water injection pipe and a first water outlet pipe. A clamping area for clamping a transparent film is formed between the pressing roller and the laser roller. A power cylinder is hinged to the main machine, and the power shaft of the power cylinder is hinged to the support frame.

[0007] To implement the above technical solution, the power cylinder is started, and the power shaft pushes the support frame to move toward the laser roller.

Through the pressure of the power shaft, embossing is formed on the transparent film to obtain a laser film. The laser film is wound by the winding roller, and hot oil is injected into the oil guide hole from the oil filling pipe, and then the hot oil is discharged from the oil outlet pipe to realize hot oil circulation, so that the laser roller can be heated. Passing cold water through the cooling pipe can cool the cooling pipe, and the cooling pipe contacts the pressure roller, so that the pressure roller can be cooled. By adjusting the flow rate of cold water and hot oil, the temperature of the transparent film when passing between the laser roller and the pressure roller can be adjusted to adapt to different production needs and achieve the purpose of improving practicality.

[0009] To implement the above technical solution, the transparent film bypasses the conductive roller and the adjusting rod and passes between the pressure roller and the laser film. By rotating the cross bar, the transparent film moves toward the laser roller or the pressure roller, so that the transparent film can be preheated or precooled to improve production quality.

[0010] As a preferred solution of the utility model, a cooling roller is rotatably connected to the main machine, and the two ends of the cooling roller are respectively rotatably connected to the second water injection pipe and the second water outlet pipe, the cooling roller, the second water injection pipe and the second water outlet pipe are connected, a placement rack is hingedly connected to the main machine, and a conveying roller is rotatably connected to the placement rack, a transmission area is formed between the conveying roller and the cooling roller, and a pressure cylinder is hingedly connected to the main machine, and the pressure shaft of the pressure cylinder is hinged to the placement rack.

[0011] To implement the above technical solution, cold water is injected into the cooling roller from the second water injection pipe and then discharged from the second water outlet pipe to realize cold water circulation to cool the cooling roller. After the transparent film passes between the pressure roller and the laser roller to obtain the laser film, the laser film is cooled by the cooling roller to quickly shape it, thereby reducing the deformation of the laser film and achieving the purpose of improving production quality.

[0012] As a preferred solution of the utility model, a support rod is rotatably connected to the main machine, a connecting rod is fixedly connected to the support frame, bristles are connected to the connecting rod, and the bristles face the support rod.

[0013] To implement the above technical solution, after the laser film is cooled by the cooling roller and passes around the support rod, it is rolled up by the receiving roller. The brush hairs contact the laser film and can sweep away the dust on the surface of the laser film, so that the laser film is not easily damaged during the winding process.

The adjustment rod 54 moves along the crossbar 52 and pushes the transparent film to move closer to the pressure roller 33 or the laser roller 2.

[0034] A horizontally arranged driving rod 55 is rotatably connected to the main machine 1, and a rotating wheel 56 is fixedly connected to the driving rod 55. The rotating wheel 56 is located outside the main machine 1.
