Technical Field

[0001] The utility model relates to the technical field of hot stamping, in particular to a hot stamping machine for paper products. Background Art

[0002] Hot stamping is also known as hot stamping. Hot stamping refers to the process of hot stamping the aluminum layer on the hot stamping film onto the surface of the substrate under a certain temperature and pressure according to the style of the hot stamping die. The hot stamping machine is the equipment to complete the hot stamping process. The process mainly uses the principle of heat transfer to transfer the aluminum layer to the substrate. As the pressure of the hot stamping die is removed, the aluminum layer adheres to the substrate to complete the hot stamping process.

DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1-Figure 4 As shown, a paper product hot stamping machine proposed in this embodiment includes a frame 1 and a hot stamping component, the frame 1 has a hot stamping channel 101, and a closed window 11, a conveying component and a fixing mechanism are arranged at the hot stamping channel 101, the fixing mechanism includes a driving component arranged on the frame 1, and a fixing component cooperating with the driving component to fix the winding roller; the hot stamping component is arranged on the frame 1, and the hot stamping component includes a cylinder 2 arranged on the top of the frame 1, a mounting frame 3 connected to the output end of the cylinder 2, a heating component arranged on the mounting frame 3, a hot stamping plate 4 slidably and detachably arranged on the mounting frame 3, and a threaded rod 5 threadedly connected to the hot stamping plate 4 and the mounting frame 3, and the hot stamping plate 4 is located at the closed window 11.

[0021] The conveying assembly includes a motor a10 arranged on a frame 1, an active roller 8 connected to the output end of the motor a10, a driven roller 7 rotatably arranged on the frame 1, and a conveyor belt 9 arranged on the active roller 8 and the driven roller 7. A support block is arranged between the active roller 8 and the driven roller 7. The height of the support block is smaller than the diameter of the active roller and the driven roller 7. When the paper product is on the conveyor belt 9, the support block will support the conveyor belt 9 from below the conveyor belt 9 to avoid the failure of hot stamping due to the lack of a bearing point at the bottom when the hot stamping plate hot stamps the paper product.

[0022] The hot stamping plate 4 includes a sliding block portion 41 slidably arranged on the mounting frame 3, and a hot stamping plate portion 42 arranged at the bottom of the sliding block portion 41. The threaded rod 5 is threadedly connected to the sliding block portion 41. A hand wheel is arranged at one end of the threaded rod 5 facing the closed window 11. The sliding block portion 41 is T-shaped, so as to prevent the hot stamping plate 4 from sliding off the mounting frame 3 when hot stamping paper products. The hot stamping plate portion 42 is made of material with poor thermal conductivity, and the sliding block portion 41 is made of material with good thermal conductivity. An observation window is arranged on the closed window 11.

[0023] When this embodiment is used, the worker conveys the paper products to the conveying assembly, and the conveyor belt 9 conveys the paper products one by one to the bottom of the hot stamping plate 4. The hot stamping foil is set on the fixed assembly through the winding roller, and the driving assembly gradually moves the hot stamping foil between the hot stamping plate 4 and the conveyor belt 9. The heating assembly heats the hot stamping plate 4 to a temperature sufficient for hot stamping. The cylinder 2 drives the mounting frame 3 to descend, and the mounting frame 3 drives the hot stamping plate 4 to descend until the hot stamping plate 4 abuts against the paper product. When the hot stamping plate 4 needs to be replaced, the worker rotates the threaded rod 5 through the hand wheel to disengage the threaded connection between the threaded rod 5 and the mounting frame 3, and then the worker pulls the hot stamping plate 4 out of the mounting frame 3. The worker can hold the two threaded rods 5 to avoid burns to his hands and increase the production speed of paper products.

[0024] Embodiment 2

[0025] like Figure 1-Figure 4 As shown, a paper product hot stamping machine proposed in this embodiment, compared with the first embodiment, in this embodiment, the driving component includes a motor b12 arranged on the frame 1, a pulley a13 and a pulley b16 rotatably arranged on the frame 1, and a transmission belt 17 arranged on the pulley a13 and the pulley b16, the motor b12 is drivingly connected to the pulley a13, the pulley a13 and the pulley b16 have a fixed groove at one end away from the motor b12, and a guide hole is provided on the frame 1, the guide hole is located at the fixed groove, and the diameter of the guide hole gradually decreases as the distance between the guide hole and the fixed groove decreases.

[0026] In this embodiment, the worker connects one end of the winding roller with the hot stamping foil to the fixed groove. When the paper product is hot stamped, the motor b12 drives the pulley a13 to rotate, and the pulley a13 drives the pulley b16 to rotate through the transmission belt 17. At the same time, the pulley a13 and the pulley b16 both drive a winding roller to rotate through the fixed groove, so that the hot stamping foil can be stably moved from one winding roller to another winding roller, thereby avoiding the used hot stamping foil being still under the hot stamping plate 4 and affecting the production of paper products.

[0027] Embodiment 3

[0028] like Figure 1-Figure 4 As shown, a paper product hot stamping machine proposed in this embodiment, compared with the first embodiment, in this embodiment, the fixing component includes two clamping components corresponding to the pulley a13 and the pulley b16 respectively, the clamping component includes a sliding frame 14 slidably set on the frame 1, and a spring 15 connected to the sliding frame 14 and the frame 1 at both ends respectively, the sliding frame 14 is coaxial with the pulley a13 or the pulley b16, the sliding frame 14 includes a sliding column portion abutting against one end of the winding roller, a guide rod portion slidably set on the frame 1, and a limiting column portion for limiting the position of the sliding column portion, and a spring 15 is arranged on each of the multiple guide rod portions.

[0029] Two guide rods 6 are arranged side by side in the hot stamping channel 101. The guide rods 6 are located below the two sides of the hot stamping plate 4. The hot stamping foil moves from one winding roller to the two guide rods 6 and then to the other winding roller, so that the distance between the hot stamping foil and the paper product is reduced, thereby avoiding the hot stamping foil from being pulled into cracks when the hot stamping foil is pressed down.

[0030] In this embodiment, one end of the winding roller first abuts against the sliding column, and the sliding column is pressed down until the axis of the winding roller is consistent with the axis of the sliding column, and then the other end of the winding roller abuts against the pulley a13 or the pulley b16, thereby reducing the difficulty of installing the winding roller and improving the production speed of paper products.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
