Description

Technical Field

[0001] This utility model relates to the field of hot stamping machine technology, specifically a hot stamping machine for the outer surface of packaging paper bags. Background Technology

[0002] Hot stamping machines are devices used for hot stamping decoration. By heating and pressurizing, the metal plating layer (such as the aluminum layer) in hot stamping foil (electroplated aluminum) is peeled off from the polyester film substrate under certain temperature and pressure, transferred and bonded to the surface of substrates such as paper, plastic, leather, and fabric, forming patterns, text or designs with a metallic luster. This enhances the decorativeness, grade and visual appeal of the product, and is widely used in surface decoration processes in printing and packaging, clothing and textiles, leather products and other fields.

[0003] The existing Chinese utility model patent with publication number CN211994655U discloses a hot stamping machine for the outer surface of packaging paper bags. This machine includes a frame with a hot stamping base in the middle, a hot stamping die above the base, and a cylinder above the die. The frame has a feeding drum at the inlet and a take-up drum at the outlet, with tension adjustment mechanisms above both drums. Guide rollers are located at both ends of the base. Two symmetrically distributed hinge frames are hinged to the front and rear sides of the hot stamping die, with flattening rollers mounted on them. This utility model effectively ensures constant tension in the hot stamping film.

[0004] Currently, the hot stamping machines used for the outer surface of packaging paper bags still have the following problems:

[0005] When hot stamping is done on packaging paper bags, the hot stamping foil needs to be rolled up after the stamping process. Due to the large demand for hot stamping on packaging paper bags, and the limited quantity of hot stamping foil that can be rolled up each time, the hot stamping foil needs to be changed frequently during the hot stamping process. When rolling up the hot stamping foil, one end needs to be pressed manually to fix it and prevent the foil from becoming loose or falling off. Manual pressing is not only time-consuming but can also cause the hot stamping foil to shift, affecting the pressing position on the packaging paper bag. Furthermore, it can easily damage other parts of the packaging paper bag during the hot stamping process, affecting the integrity of the packaging paper bag surface. Utility Model Content

[0006] The purpose of this utility model is to provide a hot stamping machine for the outer surface of packaging paper bags to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a hot stamping machine for the outer surface of packaging paper bags, including a processing table, a protective plate structure and a take-up roller. The protective plate structure is located on one side above the processing table, and the take-up roller is rotatably installed on the rear side of one side of the processing table. Sliders are installed on both sides of the bottom of the protective plate structure, and the sliders are located in the grooves opened on the surface of the processing table. A sliding cover is slidably installed on one side of the protective plate structure.

[0009] The take-up roller includes reels near both ends, and a paper clamping roller is attached above the take-up roller. A balance block is installed at the bottom of one end of the paper clamping roller, and the balance block is located at both ends of the balance roller. A bottom rod is connected above the balance block at one end, and the bottom rod is connected to the midpoint of the bottom of the presser. A bottom block is provided at the bottom end of the balance roller at one end.

[0010] Preferably, the protective plate structure is slidably located above the work platform, and an equipment block is fixedly installed above the slider. The equipment block is connected to the four vertices of the bottom of the protective plate structure. The protective plate structure and the work platform have the same dimensions, and the work platform is welded above the processing table.

[0011] Preferably, the presser is installed on one side of the reel, and a rotating ring is rotatably connected between the balance rollers. A bottom block is also connected below the balance roller at the bottom of the paper clamping roller, and the bottom block and the balance block are located on the upper and lower sides of the balance roller, respectively.

[0012] Preferably, a frame is fixedly welded to one side of the upper part of the processing table, and a pressure device is installed on the top of the frame. A hot stamping plate is movably connected below the pressure device, and a pressure column is connected above the hot stamping plate. A unwinding roller is installed on one side of the middle of the frame, and hot stamping foil is wound around the outside of the unwinding roller.

[0013] Preferably, a belt is rotatably mounted behind the unwinding roller, and a motor is mounted on one side of the belt. The unwinding roller is fixedly mounted between support frames, and the bottom of the support frame is sleeved on the outside of the support column. One side of the support column is fixedly connected to the connecting plate, and a correction roller is mounted on one side of the support column.

[0014] Preferably, the connecting plate is fixedly connected to the rear of the hot stamping plate, and the connecting plate extends on both sides of the hot stamping plate.

[0015] Preferably, the working platform is located below the hot press plate, and the unwinding roller and the rewinding roller are raised and lowered synchronously through the hot press plate.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. When the packaging paper is hot stamping, the paper clamping roller on one side of the take-up roller is pressed down and opened, which can wrap and fix one end of the hot stamping paper, making it easy to directly roll and assemble the hot stamping paper later. After the hot stamping paper is fixed by the paper clamping roller, it is not easy to shift, so that the position of the hot stamping paper remains consistent when pressed, ensuring the accuracy of the pattern hot stamping. In addition, the tension adjustment of the take-up roller and the unwind roller makes the tension of the paper uniform during winding, reducing material waste.

[0018] 2. When the packaging paper is hot stamping, the protective plate structure protects the upper part of the work platform by sliding the slider, and then exposes the area to be hot stamped by the sliding cover. The work platform protects the hot stamping edge of the packaging paper bag to prevent the edge of the packaging paper bag from being damaged by hot stamping. In addition, the protective plate structure can be replaced by installing the insert, which is convenient for changing different styles of hot stamping patterns and ensuring that the edge of the pattern is hot stamped completely.
