Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, the die pressing system capable of performing die pressing in a nesting manner includes an unwinding unit 1, a die pressing unit, a winding unit 2, and a nesting device, wherein the unwinding unit 1 and the winding unit 2 are of conventional design, and a cursor is printed on a curled film on the unwinding unit 1. A plurality of guide rollers are arranged at the downstream of the unwinding unit 1 along the travelling path of the film. After the film comes out from the unreeling unit 1, the film is guided by a guide roller to enter a traction roller and enters a mould pressing unit through the traction roller. The mould pressing unit comprises a mould pressing plate roller 3, a main rubber roller 4 and a back pressure cooling roller 5, and an optical plate is arranged on the mould pressing plate roller 3.
In this embodiment, the positioning device includes a floating roller 6 as an adjusting component disposed between the embossing unit and the unwinding unit 1, a first color mark sensor 7 as a first sensor disposed between the floating roller 6 and the embossing roller 3, a second color mark sensor (not shown) as a second sensor disposed beside the embossing roller 3, and an encoder (not shown) connected to the embossing roller 3,
the floating roller 6 is connected with a driving device, so that the floating roller 6 can be pressed on the film and can move relative to the film, and the film is stretched to adjust the length of the film before entering the mould pressing roller 3;
the first color mark sensor 7 is positioned above the film, detects a color mark on the film and sends a detected signal to a controller, such as a PLC (programmable logic controller), and the controller is matched to control the action of the floating roller 6;
the second color mark sensor is positioned beside the molding plate roller 3 to detect the position of the original point of the molding plate roller 3. The original point position of the mould pressing plate roller 3 can be set according to the pattern on the optical plate, and the original point position mainly records the rotating position of the mould pressing plate roller 3;
by the arrangement of the second patch sensor, a process distance is established between the second patch sensor and the first patch sensor 7, the process distance is a virtual distance and is formed according to the image on the film and the position of the mold pressing; when the length of the film between the first color mark sensor 7 and the second color mark sensor meets the process distance, the pattern on the optical plate can be accurately stamped on the film; in this embodiment, the process distance is recorded in the pulse time of the encoder;
the encoder is connected with the mould pressing plate roller 3 to record the rotating position of the mould pressing plate roller 3; the encoder is in communication connection with the second color mark sensor, and the controller is in communication connection with the encoder and the second color mark sensor.
The operation of the molding system of this embodiment is as follows:
the film printed or simultaneously aluminized with the cursor is placed in the unwinding unit 1. After being sent out by the unreeling unit 1, the films are sequentially unfolded, enter the floating rollers 6 of the nesting device through the guide rollers 8, are guided by the guide rollers 8 after passing through the floating rollers 6 positioned at the upstream of the mould pressing plate roller 3, and enter the mould pressing unit through the traction rollers 9. The back pressure cooling roller 5 is pressed by a hydraulic cylinder to push the main rubber roller 4 forwards so as to tightly press the film on the molding plate roller 3. When in mould pressing, the mould pressing roller 3 is heated by a heating system, and the temperature can reach 80-250 ℃. The embossing roll 3 transfers the temperature to the optical plate and film thereon. Through pressure and high temperature, an optical image on the optical plate can be accurately imprinted on the film, the imprinted optical film is led out through a traction cooling device, such as a glue pressing roller 10 and a traction cooling roller 11, the glue pressing roller 10 applies pressure through an air cylinder to tightly press the imprinted optical film on the traction cooling roller 11 for cooling and setting, and the imprinted film is sent to a winding unit 2 for winding through a guide roller 8, so that the whole process is completed.
In the above process, when the film passes through the first color sensor 7, the first color sensor 7 detects the cursor on the detection film and sends a signal to the controller. And then, when the film passes through the mould pressing plate roller 3, the second color mark sensor near the mould pressing plate roller 3 and the encoder on the mould pressing plate roller 3 immediately give an origin signal and an encoder signal, the controller simultaneously receives the origin signal, the encoder signal and the signal given by the first color mark sensor 7 and then analyzes the signals, and the pulse time of the difference between the length of the film between the first color mark sensor 7 and the second color mark sensor and the process distance in the actual production can be obtained by combining the actual stamping effect of the stamped film. According to the pulse time difference between the process distance and the length of the film, the controller drives the floating roller 6 to float up and down to change the length of the film before entering the molding plate roller 3, so that the length of the film is equal to the process distance. Thus, when the film passes through the mould pressing plate roller 3, patterns on the optical plate can be accurately subjected to register mould pressing.
The preferred embodiment of the present invention is only listed in the present specification, and all the technical changes equivalent to those made under the working principle and thought of the present invention are considered as the protection scope of the present invention.
