Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1 As shown, the present application provides a printing tension control device, including a mounting plate 1, a roll-out assembly 2 is arranged on the mounting plate 1, the roll-out assembly 2 is used to roll out the hot stamping paper, and a tension adjustment assembly 3 is arranged on the mounting plate 1, the tension adjustment assembly 3 is used to adjust the tension of the hot stamping paper, and a winding assembly 5 is arranged on the mounting plate 1, the winding assembly 5 is used to wind up the hot stamping paper that has been consumed, specifically:

[0026] like Figure 1 As shown, the unwinding assembly 2 includes a servo motor 21 fixedly mounted on the mounting plate 1, and the output end of the servo motor 21 is fixedly connected to a unwinding roller 22, on which a hot stamping paper roll is arranged, and at the same time, a transition roller 23 is rotatably mounted on the mounting plate 1, and the transition roller 23 is located below the unwinding roller 22;

[0027] like Figure 1-Figure 3 As shown, the tension adjustment assembly 3 includes a mounting frame 37 fixedly mounted on the mounting plate 1, and two groups of mounting boxes 32 are arranged on the mounting frame 37. At least two groups of mounting holes 38 for fixing the mounting boxes 32 are opened on the mounting frame 37, so as to adjust the distance between the two groups of mounting boxes 32;

[0028] Meanwhile, a screw rod 34 is rotatably installed inside the installation box 32, a knob 31 is fixedly installed on the top of the screw rod 34, and a fixing block (not shown in the figure) is threadedly installed on the screw rod 34. Meanwhile, a slide groove 33 for the sliding of the fixing block is provided on the installation box 32, and a support frame 35 is fixedly installed on the fixing block. Two sets of tension rollers 36 are provided on the support frame 35 to adjust the tension on the transmission path of the hot stamping paper.

[0029] like Figure 1 As shown, the winding assembly 5 includes a transition roller 53 rotatably mounted on the mounting plate 1, and a paper reel 52 is rotatably mounted on the mounting plate 1, and a paper pressing roller 54 is arranged on the mounting plate 1, the paper pressing roller 54 is used to press the hot stamping paper, and the paper pressing roller 54 is located on one side of the paper reel 52, a stepping motor (not shown in the figure) is fixedly mounted on the mounting plate 1, and a winding roller 51 is fixedly mounted on the output end of the stepping motor, and the winding roller 51 is located above the paper reel 52;

[0030] In summary, when installing the hot stamping paper, the hot stamping paper roll of the unwinding roller 22 is pulled out, and then the hot stamping paper is attached to the transition roller 1 23 and bypassed from the transition roller 1 23, and then the hot stamping paper is passed between the two sets of tension rollers 36, and then the hot stamping paper is attached to the transition roller 2 53 and bypassed from the transition roller 2 53, and then the hot stamping paper passes between the pressing roller 54 and the paper winding wheel 52, and is fixed on the winding roller 51, at this time, the hot stamping paper transmission path is formed, and then the servo motor 21 and the stepper motor are turned on to form a circulation operation of the hot stamping paper;

[0031] When facing hot stamping papers of different materials and sizes, the tension of the hot stamping papers needs to be adjusted. At this time, the knob 31 is rotated with the screw rod 34, thereby driving the fixed block to move up and down along the axis, thereby adjusting the height of the two sets of support frames 35, that is, adjusting the height of the two sets of tension rollers 36 on the support frames 35, so that the tension on the hot stamping paper transmission path can be adjusted, and according to actual conditions, the horizontal distance between the two sets of mounting boxes 32 can be adjusted through the mounting holes 38 on the mounting frame 37, that is, adjusting the horizontal distance between the tension rollers 36 on the two sets of support frames 35, so as to further adjust the tension on the hot stamping paper transmission path;

[0032] In the above implementation process, the distance between the two sets of tension rollers 36 is fixed. At this time, when facing hot stamping papers of different thicknesses, the distance between the two sets of tension rollers 36 cannot be adjusted according to the actual situation, resulting in a lot of gold powder being scraped off when the thicker hot stamping paper passes between the two sets of tension rollers 36, thereby affecting the hot stamping printing effect. In order to solve this problem, an adaptive component 4 is provided on the support frame 35, and the adaptive component 4 is used for transmitting different hot stamping papers, specifically:

[0033] like Figure 1-Figure 2 As shown, the adaptive component 4 includes two groups of movable grooves 41 opened on the support frame 35, wherein two ends of a group of tension rollers 36 are slidably arranged in the two groups of movable grooves 41, and springs 42 are arranged between the two ends of the tension roller 36 and the inner walls of the two groups of movable grooves 41. Due to the elasticity of the spring 42 itself, the tension roller 36 can adapt to hot stamping papers of different sizes;

[0034] When facing hot stamping papers of different thicknesses, when the hot stamping papers pass through the gap between the two sets of tension rollers 36, the thicker hot stamping paper can push up one set of tension rollers 36. At this time, the spring 42 will be compressed, thereby pressing against the tension rollers 36 to exert a certain downward pressure, thereby being able to adapt to the transmission of different hot stamping papers.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
