DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a molding press device for a molding printing machine.

[0030] See also Figure 1-2, a embossing press device for an embossing printing machine, comprising: an embossing roller 1, a mounting bracket 5, a first pressing component 6, a second pressing component 7, and a guide strip 8; a heating roller 2 is arranged inside the embossing roller 1, and the outer wall of the heating roller 2 is in close contact with the inner wall of the embossing roller 1; guide rollers 51 are arranged on both sides of the mounting bracket 5, and the mounting bracket 5 is provided with a limiting roller 3, and the limiting roller 3 is in close contact with the embossing roller 1; the first pressing component 6 acts on the mounting bracket 5; the second pressing component 7 is mounted on the mounting bracket 5, and comprises a pressing roller 71, and pressure is applied to the limiting roller 3 through the pressing roller 71; the guide strip 8 matches the guide roller 51, and is used to guide the mounting bracket 5; wherein the heating roller 2 is heated in sections in the axial direction, the first pressing component 6 pushes the mounting bracket 5, and the mounting bracket 5 moves under the guidance of the guide strip 8, the embossing roller 1 is mounted on the mounting bracket 5, and the embossing roller 1 and the mounting bracket 5 move synchronously.

[0031] It can be understood that when the embossing is performed, the heating roller 2 generates heat to preheat the embossing roller 1, thereby increasing the temperature of the embossing roller 1. Since the heating roller 2 is heated in sections in the axial direction, the preheating process of the embossing roller 1 can be shortened, and the heating of the embossing roller 1 is more uniform and controllable. After the embossing roller 1 is preheated, the first pressure component 6 applies pressure to the mounting bracket 5, and the mounting bracket 5 moves in cooperation with the guide bar 8 and the guide roller 51, thereby driving the limiting roller 3 and the embossing roller 1 to move synchronously, so that the embossing roller 1 is subjected to pressure, and the limiting roller 3 limits the embossing roller 1, so that the force on the embossing roller 1 is more uniform. The embossing roller 1 is uniformly stressed and heated, thereby ensuring that the pressure of the embossing roller 1 on the printed matter is uniform during the embossing, thereby improving the printing quality of the printed matter.

[0032] Specifically, the first pressurizing assembly 6 includes two first hydraulic cylinders 61 , and the first hydraulic cylinders 61 are respectively disposed at two ends of the mounting bracket 5 .

[0033] It can be understood that the first hydraulic cylinder 61 applies pressure to both ends of the mounting bracket 5 , thereby ensuring that both ends of the mounting bracket 5 translate synchronously, thereby ensuring that the printing roller 1 is evenly stressed.

[0034] Furthermore, a first pressure sensor 62 is provided at the junction of the first hydraulic cylinder 61 and the mounting bracket 5 .

[0035] It can be understood that the pressure between the first hydraulic cylinder 61 and the mounting bracket 5 is monitored by the first pressure sensor 62. When it is detected that the pressure values ​​of the first pressure sensor 62 at both ends of the mounting bracket 5 are inconsistent, the hydraulic pressures of the first hydraulic cylinders 61 at both ends of the mounting bracket 5 are adjusted respectively to make the pressure values ​​at both ends of the mounting bracket 5 equal, thereby ensuring the synchronous translation of the two ends of the mounting bracket 5, thereby ensuring that the printing roller 1 is evenly stressed and improving the molding quality.

[0036] Specifically, the second pressurizing assembly 7 includes a second hydraulic cylinder 72 , which is mounted on the mounting bracket 5 , and a pressurizing roller 71 is mounted on the output end of the second hydraulic cylinder 72 . When the second hydraulic cylinder 72 is extended, the pressurizing roller 71 presses the limiting roller 3 .

[0037] It can be understood that when embossing is performed, the output end of the second hydraulic cylinder 72 is pushed out, and the pressure roller 71 is used to apply pressure to the limiting roller 3, and the limiting roller 3 limits and presses the embossing roller 1, thereby ensuring that the pressure of the embossing roller 1 on the printed matter is uniform during embossing, thereby improving the printing quality of the printed matter.

[0038] Furthermore, a second pressure sensor 73 is provided between the second hydraulic cylinder 72 and the pressure roller 71 .

[0039] It can be understood that the pressure applied by the second hydraulic cylinder 72 to the pressure roller 71 is monitored by the second pressure sensor 73, and then the pressure values ​​monitored by the second pressure sensor 73 and the first pressure sensor 62 are compared and calculated, and then the hydraulic pressure of the second hydraulic cylinder 72 and the first hydraulic cylinder 61 are adjusted according to the calculated result, thereby further ensuring that the pressure of the printing roller 1 on the printed product is uniform during molding, thereby improving the printing quality of the printed product.

[0040] Furthermore, the number of the limiting rollers 3 is two.

[0041] It can be understood that when the limiting rollers 3 limit and press the printing roller 1, the two limiting rollers 3 limit and press the printing roller 1 at the same time, further making the printing roller 1 evenly stressed, thereby improving the printing quality of the printed product.

[0042] Furthermore, a third pressure sensor 52 is installed at the connection between the printing roller 1 and the mounting bracket 5 .

[0043] It can be understood that the pressure between the printing roller 1 and the mounting bracket 5 is monitored by the third pressure sensor 52. There are two connections between the printing roller 1 and the mounting bracket 5, which are located at the two ends of the printing roller 1. The pressure values ​​monitored by the third pressure sensors 52 at the two connections are compared and calculated. When the pressure values ​​monitored by the third pressure sensors 52 at the two connections are not equal, the hydraulic pressures of the first hydraulic cylinder 61 and the second hydraulic cylinder 72 are adjusted in combination with the pressure values ​​monitored by the first pressure sensor 62 and the second pressure sensor 73, so that the printing roller 1 is evenly stressed, thereby improving the printing quality of the printed product.

[0044] Furthermore, at least one fourth pressure sensor 4 is disposed inside the limiting roller 3 , and the fourth pressure sensors 4 are evenly distributed along the axial direction of the limiting roller 3 .

[0045] It can be understood that the pressure of the limiting roller 3 on the printing roller 1 is monitored by the fourth pressure sensor 4, and the fourth pressure sensor 4 is evenly distributed along the axial direction of the limiting roller 3. According to the pressure value monitored by the fourth pressure sensor 4, the hydraulic pressure of the second hydraulic cylinder 72 is adjusted in real time, so that the printing roller 1 is evenly stressed, thereby improving the printing quality of the printed product.

[0046] Furthermore, the heating roller 2 is provided with a plurality of temperature sensors 9 , and the temperature sensors 9 are evenly distributed along the axial direction of the heating roller 2 .

[0047] It can be understood that the temperature sensor 9 monitors the heating amount of each part of the heating roller 2 in real time, and then adjusts the heating amount of each section of the heating roller 2 in real time to ensure that the heating amount of each part of the heating roller 2 is uniform, thereby ensuring that the heating roller 2 heats the printing roller 1 uniformly, thereby improving the printing quality of the printed product.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
