Description

Technical Field

[0001] This application relates to the field of hot stamping apparatus technology, and in particular to a hot stamping apparatus. Background Technology

[0002] Hot stamping is a common surface decoration process that involves applying a hot stamping film to the surface of a substrate, allowing it to bond with the ink layer to create a metallic sheen or special textured effect. Currently, hot stamping technology is widely used in packaging, printing, and decoration, and market demand continues to grow.

[0003] In existing technologies, hot stamping processes typically employ hot pressing, which involves directly transferring the hot stamping film to the surface of the substrate through heating and pressure. However, this method requires a high degree of dryness of the ink layer and is prone to the hot stamping film peeling off or shifting. In other words, traditional hot pressing is highly dependent on the dryness of the ink layer. If the ink is not completely dry, the hot stamping film is likely to peel off or shift.

[0004] Therefore, this application provides a hot stamping apparatus. Summary of the Invention

[0066] Example 2

[0067] Based on Example 1, referring to Figures 7 to 10 And unlike Example 1, the following is true:

[0068] Please refer to this carefully. Figure 7 , Figure 8 A dust removal mechanism 600 is provided on the surface of the conveyor plate 101 on the right side of the inkjet mechanism 200, which is used to clean the dust on the surface of the plastic plate before inkjet printing.

[0069] Specifically, the dust removal mechanism 600 can automatically remove dust from the plastic surface that is about to enter the inkjet frame 201.

[0070] Please refer to this carefully. Figure 7 , Figure 8 The dust removal mechanism 600 includes a rectangular box 601 fixed on the back of the conveyor plate 101, and a pipe 602 disposed on the upper surface of the conveyor plate 101 and corresponding to the conveyor belt 102.

[0072] Please refer to this carefully. Figure 7 , Figure 8 One end of the right rotating shaft 104 extends to the back of the conveying plate 101 and is provided with a rotating disk 605 for continuously pushing the sealing piston plate 604. A connecting post 606 is fixed on the surface of the rotating disk 605, and a limiting block is fixed at the end of the connecting post 606.

A second rotating hole is opened on the outer surface of the other end of the connecting rod 609, which is rotatably connected to the outer surface of the connecting shaft 608.

[0073] Specifically, the rotation of the rotating shaft 104 can drive the rotating disk 605 to rotate, and the rotation of the rotating disk 605 drives the connecting rod 609 to continuously push and pull the sealing piston plate 604, thereby realizing the reciprocating movement of the sealing piston plate 604.

[0074] Please refer to this carefully. Figure 9 , Figure 10 An inflation tube 6010 and an air intake tube 6011 are respectively provided on the side of the upper surface of the rectangular box 601. One end of the inflation tube 6010 extends into the interior of the rectangular box 601, and the other end of the inflation tube 6010 extends into the interior of the pipe 602.

[0075] Specifically, when the sealing piston plate 604 is pulled, external air can be drawn into the rectangular box 601 through the suction pipe 6011. When the sealing piston plate 604 is pushed, the air inside the rectangular box 601 can be transported to the pipe 602 through the inflation pipe 6010 and sprayed out through the jet nozzle 603 to timely and fully remove dust from the surface of the plastic plate on the conveyor belt 102 that is about to enter the inkjet frame 201.

[0076] In this embodiment, by setting up a dust removal mechanism 600, when the device hot stamps the plastic sheet, during the process of the drive motor 105 driving the conveyor belt 102 to rotate, the rotation of the rotating shaft 104 can drive the rotating disk 605 to rotate. The rotation of the rotating disk 605 drives the connecting rod 609 to continuously push and pull the sealing piston plate 604, thereby realizing the reciprocating movement of the sealing piston plate 604. When the sealing piston plate 604 is pulled, external air can be drawn into the rectangular box 601 through the air suction pipe 6011. When the sealing piston plate 604 is pushed, the air inside the rectangular box 601 can be transported to the pipe 602 through the air filling pipe 6010 and sprayed out through the jet nozzle 603 to timely and fully remove dust from the surface of the plastic sheet on the conveyor belt 102 that is about to enter the inkjet frame 201, ensuring the uniformity of ink spraying on the plastic sheet and ensuring the quality of the plastic sheet after hot stamping.

[0077] Working principle:

[0078] In actual use, the modified hot stamping device can drive a rotating shaft 104 to rotate via the rotation of the drive motor 105. The rotation of the rotating shaft 104 drives a conveyor roller to rotate, thereby driving the conveyor belt 102 to automatically convey the plastic sheet. During the conveying process, the plastic sheet is placed into the rightmost placement slot 103 in sequence. After the plastic sheet in the placement slot 103 enters the inkjet frame 201, the drive motor 105 is turned off, and the first hydraulic rod 204 is activated to move the clamping frame 205 downward to clamp the plastic sheet. At the same time, the ink pump is activated to deliver ink to the inkjet printer. Inside the tube 202, ink is sprayed onto the surface of the plastic sheet through the atomizing nozzle 203. The electric guide rail 206 is activated, driving the inkjet tube 202 to reciprocate, achieving uniform ink spraying onto the plastic sheet surface. After drying under a UV lamp, hot stamping is performed. During hot stamping, the rotation of the rotary motor 406 automatically unwinds the hot stamping film, while the hot press roller 407 effectively adheres the film to the surface of the plastic sheet. Finally, after the hot stamping film is adhered, as the plastic sheet is conveyed into the hot press frame 501, the drive motor 105 is turned off, and the second hydraulic rod 503 is activated. The hot press plate 502 moves downward to further heat-press and fix the hot stamping film, thereby enabling streamlined hot stamping operations on plastic sheets, effectively improving work efficiency. Furthermore, it allows for timely and thorough drying of the ink on the plastic sheet after inkjet printing, preventing the hot stamping film from detaching or shifting during hot pressing. Additionally, as the drive motor 105 rotates the conveyor belt 102, the rotation of the shaft 104 drives the rotating disk 605 to rotate. The rotation of the rotating disk 605 causes the connecting rod 609 to continuously push against the sealing piston plate 604. Pulling the sealing piston plate 604 enables its reciprocating movement. When the sealing piston plate 604 is pulled, external air is drawn into the rectangular box 601 through the suction pipe 6011. When the sealing piston plate 604 is pushed, the air inside the rectangular box 601 is transported to the pipe 602 through the inflation pipe 6010 and sprayed out through the jet nozzle 603 to promptly and thoroughly remove dust from the surface of the plastic plate on the conveyor belt 102 that is about to enter the inkjet frame 201. This ensures the uniformity of ink spraying on the plastic plate and the quality of the plastic plate after hot stamping.
