Description

Technical Field

[0001] The utility model belongs to the technical field of hot stamping equipment, and specifically relates to a missing hot stamping recognition device for a hot stamping machine. Background Technique

[0002] Hot stamping refers to the process of hot stamping an aluminized foil onto the surface of a substrate under certain temperature and pressure. The patterns hot stamped with aluminized foil present a strong metallic luster, with bright and vivid colors that never fade. Especially for gold and silver aluminized foils, they adorn the surface of printed materials with their magnificent, delicate and elegant decoration, enhancing the artistry of the printed matter and achieving a prominent theme publicity effect; their brightness far exceeds that of printing gold and silver, giving the product a high-class feeling and a beautiful enjoyment. At the same time, due to the excellent physical and chemical properties of aluminized foil, it plays a role in protecting the printed matter. Therefore, the hot stamping process is widely used in high-grade and delicate packaging and decoration trademarks, calendars, book covers and other printed materials.

[0003] After retrieval, a document with the publication number (CN216659314U) discloses an on-line detection device for the hot stamping quality of a hot stamping machine, including: a backlight source and a line array camera for illuminating the back of the hot stamping paper. The backlight source is installed on the frame of the hot stamping machine through a backlight source bracket, and the line array camera is installed on the frame of the hot stamping machine through a mounting bracket. In the utility model, the line array camera receives the light transmitted through the hot stamping paper, and then accesses the pattern information into the subsequent PLC.

[0005] The above device only has the function of detecting missing printing for materials similar to paper. After the above device completes the detection, the printed materials with missing printing cannot be removed from it, resulting in all the printed materials being stored in one place, and still requiring manual separation of the printed materials subsequently.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. The missing stamping recognition device of a hot stamping machine. The conveying roller sends the printed matter to the lower end of the detector, and the detector detects the printed matter. When there is missing printing on the printed matter, the inner gear of the servo motor meshes with the rack bar, and the servo motor moves up and down on the rack bar. The servo motor drives the lifting block and the suction disc on the lifting block, and the missing-printed printed matter is adsorbed and taken away by the suction disc, and the missing-printed printed matter is removed from it.

[0018] 2. The missing stamping recognition device of a hot stamping machine. The mounting block and the bracket are connected by fasteners.

[0019] 3. The missing stamping recognition device of a hot stamping machine. Manually rotate the lead screw, and the lead screw moves the adjusting rod. The distance between the adjusting rods changes to limit printed matters of different sizes, so that the printed matter is always within the detection range of the detector.

[0020] 4. The missing stamping recognition device of a hot stamping machine. When the printed matter contacts the abutting wheel, the printed matter pushes the abutting wheel to move upward. When the abutting wheel moves upward, it squeezes the spring. The spring deforms due to the extrusion and generates a downward force. Through the force of the spring, the abutting wheel is in close contact with the printed matter, restricting the position of the printed matter and preventing the printed matter from shifting during transportation, resulting in the inability to detect the printed matter.
