[0014] 1. By setting up a smoothing mechanism, when the envelope paper is fed, the elastic force of the extension spring inside the fixed frame drives the moving block to move, so that the moving block slides inside the guide groove. Under the action of the guide groove, the moving block is guided. Under the action of the extension spring, the moving block drives the smoothing plate to move until it contacts the surface of the envelope paper. Under the action of the smoothing plate, the surface of the envelope paper is smoothed. This realizes the function of smoothing the envelope paper feeding of the embossing device.

By setting up a tension adjustment mechanism, the user loosens the fastening bolts on the surface of the adjusting screw and then rotates the adjusting screw on the surface of the fixed screw, causing the adjusting screw to move on the surface of the fixed screw. When the adjusting screw moves, it drives the adjusting block to slide on the inner wall of the holding tank. When the adjusting block moves up and down, it drives the second guide roller to move up and down on the inner wall of the device housing, adjusting the position of the second guide roller, thereby adjusting the tension of the envelope paper during feeding. After adjustment, the user tightens the fastening bolts on the surface of the adjusting screw to fix the adjusting screw on the surface of the fixed screw, realizing the tension adjustment function of the die device. This allows the die device to adjust the tension of the envelope paper according to production needs, making the die device more practical in use.

By incorporating a high-efficiency hot stamping mechanism, the blowers inside the first and second heating chambers are controlled to draw air from the fixed chamber into the first and second heating chambers. The control box controls the heaters inside the first and second heating chambers to heat the air inside. A temperature monitor tracks the temperature inside the first and second heating chambers, displaying the results on the control box. The heat from the first and second heating chambers is then transferred to the upper and lower hot stamping plates, respectively, and further conducted to the surfaces of the concave and convex stamping plates. This makes the hot stamping process on the envelope paper more efficient, achieving high-efficiency hot stamping. Consequently, the hot stamping efficiency of the device is significantly improved, making it more efficient in use. Attached Figure Description

Under the action of the heaters 45, the air inside the first heating box 41 and the second heating box 42 is heated. Under the action of the temperature monitor 44, the temperature inside the first heating box 41 and the second heating box 42 is monitored, and the monitoring results are displayed on the surface of the control box 101. Subsequently, the heat inside the first heating box 41 and the second heating box 42 is transferred to the interior of the upper hot stamping plate 108 and the lower hot stamping plate 110, respectively, and then the heat is conducted to the surface of the concave template 109 and the convex template 111, so that the concave template 109 and the convex template 111 perform concave and convex hot stamping on the surface of the envelope paper 105 more efficiently, so as to realize the function of efficient hot stamping of the concave and convex mold device.

[0033] Working principle: When in use, first place the device box 1 in the designated position. When the envelope paper 105 is fed, it drives the paper tube 106 to rotate on the inner wall of the support frame 103.

Under the action of the guide groove 231, the moving block 233 is guided. Under the elastic force of the extension spring 232, the moving block 233 drives the smoothing plate 21 to keep moving until it contacts the surface of the envelope paper 105. Under the action of the smoothing plate 21, the surface of the envelope paper 105 is smoothed, so as to realize the function of smoothing the envelope paper 105 during feeding of the embossing device. Thus, the embossing device can smooth the envelope paper 105 when feeding, so that the embossing device can be more accurate when hot stamping the surface of the envelope paper 105.

[0034] Subsequently, the envelope paper 105 is guided by the combined action of the second guide roller 115 and the first guide roller 113. If it is necessary to adjust the tension of the envelope paper 105 during feeding, the user loosens the fastening bolt 36 on the surface of the adjusting screw 33, and then rotates the adjusting screw 33 on the surface of the fixing screw 35, so that the adjusting screw 33 moves on the surface of the fixing screw 35. When the adjusting screw 33 moves, the adjusting screw 33 drives the adjusting block 31 to slide on the inner wall of the holding groove 32. When the adjusting block 31 moves up and down, the adjusting block 31... The second guide roller 115 is driven to move up and down on the inner wall of the device housing 1, and the position of the second guide roller 115 is adjusted, thereby adjusting the tension of the envelope paper 105 when it is fed. After the adjustment is completed, the user tightens the fastening bolt 36 on the surface of the adjusting screw 33 to fix the adjusting screw 33 on the surface of the fixing screw 35, so as to realize the function of adjusting the tension of the die device. This allows the die device to adjust the tension of the envelope paper 105 according to the production needs, making the die device more practical in use.

[0035] Subsequently, air enters the interior of the fixed box 102 through the ventilation hole 107. The control box 101 controls the electric push rod 104 to work. Under the action of the electric push rod 104, the first heating box 41 moves downward inside the fixed box 102, causing the electric push rod 104 to drive the upper hot stamping plate 108 and the concave template 109 to move downward. This causes the upper hot stamping plate 108 to drive the concave template 109 to move until it contacts the surface of the envelope paper 105. The bottom of the envelope paper 105 contacts the surface of the convex template 111. Under the combined action of the concave template 109 and the convex template 111, the surface of the envelope paper 105 is hot stamped with concave and convex designs.

[0036] Subsequently, the control box 101 controls the blowers 43 inside the first heating box 41 and the second heating box 42 to operate. Under the action of the blowers 43, air inside the fixed box 102 is drawn into the first heating box 41 and the second heating box 42. The control box 101 then controls the heaters 45 inside the first heating box 41 and the second heating box 42 to operate. Under the action of the heaters 45, the air inside the first heating box 41 and the second heating box 42 is heated. Under the action of the temperature monitor 44, the temperature inside the first heating box 41 and the second heating box 42 is monitored, and the monitoring results are displayed on the control box 101. The heat from the first heating box 41 and the second heating box 42 is transferred to the interior of the upper hot stamping plate 108 and the lower hot stamping plate 110, respectively, and then conducted to the surfaces of the concave template 109 and the convex template 111. This makes the concave template 109 and the convex template 111 more efficient at hot stamping the surface of the envelope paper 105, thereby realizing the efficient hot stamping function of the convex and concave die device. This greatly improves the hot stamping efficiency of the surface of the envelope paper 105 when the convex and concave die device is used, making the convex and concave die device more efficient when in use, and finally completing the use of the convex and concave die device.
