[0001] This utility model belongs to the field of auxiliary recycling technology for hot stamping equipment, specifically a waste recycling mechanism for hot stamping machines. Background Technology
[0002] Hot stamping is widely used in the packaging, printing, paper, and plastic product processing industries. It uses high temperature and pressure to transfer electroplated aluminum foil onto the product surface, achieving decorative and anti-counterfeiting effects. However, the hot stamping process generates waste foil, scraps, and other waste materials that are scattered around the equipment in rolls or fragments. This requires frequent manual cleaning, is labor-intensive, and the accumulated waste takes up workshop space and poses a fire hazard. In current technologies, waste containing metal foil layers is directly treated as general solid waste, resulting in resource waste and failing to meet the circular economy requirements of green factories. Therefore, a waste recycling mechanism for hot stamping machines is proposed to address the above issues. Utility Model Content

The recycling bin has horizontally mounted slide rails fixedly installed on the middle of the two opposite inner side walls. A slidingly fitted base plate is mounted on the two slide rails. The base plate divides the recycling bin into a compression chamber and a receiving chamber. A strip-shaped opening for the base plate to enter and exit is provided on the side wall of the recycling bin between the two slide rails. The negative pressure component is used to guide the waste from the hot stamping machine into the compression chamber of the recycling bin; The compression assembly includes a gantry frame fixedly installed on the top of the recycling bin. A bidirectional lead screw is rotatably installed between the two sides of the gantry frame. The bidirectional lead screw has a forward thread section and a reverse thread section. Nuts are threaded onto the forward thread section and the reverse thread section, respectively. Connecting rods are hinged to both sides of the nuts. A compression plate is hinged to the lower end of each connecting rod. The compression plate is located in the compression chamber. The edge of the compression plate slides against the inner wall of the recycling bin.
[0005] Preferably, the inner wall of the recycling bin is provided with a guide groove along the longitudinal direction, and the end of the compression plate is provided with a slider, which is located in the guide groove.
[0006] Preferably, the negative pressure assembly includes a main conveying pipe and a negative pressure fan.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0014] Specific implementation examples are given below.
[0015] Please see Figures 1-4 This utility model provides a waste recycling mechanism for hot stamping machine, including a hot stamping machine workbench 1 and a recycling box 2. The recycling box 2 is detachably installed on one side of the hot stamping machine workbench 1. A door 206 is hinged to one side of the recycling box 2. A negative pressure component is provided on one side of the recycling box 2. The negative pressure component is used to guide the waste from the hot stamping machine into the compression chamber of the recycling box 2. A compression component is provided on the top of the recycling box 2. The compression assembly includes a gantry frame 201 fixedly mounted on the top of the recycling bin 2. A bidirectional lead screw 202 is rotatably mounted between the two sides of the gantry frame 201. The bidirectional lead screw 202 has a forward thread section and a reverse thread section. Nuts 203 are threaded onto the forward thread section and the reverse thread section, respectively. Connecting rods 204 are hinged to both sides of the nuts 203. The lower ends of all connecting rods 204 are hinged to a compression plate 205. The compression plate 205 is located in the compression chamber. The edge of the compression plate 205 slides against the inner wall of the recycling bin 2. The inner wall of the recycling bin 2 has a guide groove 208 along its longitudinal direction. A slider 207 is provided at the end of the compression plate 205. The slider 207 is located in the guide groove 208. The compression plate 205 moves smoothly up and down under the guidance of the guide groove 208 and the slider 207, avoiding deviation. Driven by an external drive motor, the bidirectional lead screw 202 rotates. The two ends of the bidirectional lead screw 202 have threads with opposite directions of rotation, which drive the two nuts 203 to move towards each other. The two nuts 203 move closer to each other, which drives the connecting rods 204 hinged on both sides to swing. The connecting rods 204 swing from the inclined state to the vertical direction, pushing the compression plate 205 downward. The compression plate 205 slides vertically downward along the guide groove on the inner wall of the recycling box 2, pressing against the loose hot stamping waste accumulated on the upper side of the bottom plate 301, compressing and reducing the volume of the waste, and compacting the loose rolled and fragmented waste foil, reducing the volume of the waste. The waste blocks are regular in shape and not scattered or broken, and can be uniformly transferred to the metal recycling process for metal foil layer peeling and recycling, effectively recycling metal resources, reducing solid waste emissions, and meeting the requirements of green factory circular economy production.
[0016] like Figure 2 and Figure 3 As shown, horizontally arranged slide rails 3 are fixedly installed on the middle of the two opposite inner side walls of the recycling bin 2. A slidingly fitted base plate 301 is mounted on the two slide rails 3, dividing the recycling bin 2 into a compression chamber and a receiving chamber. A strip-shaped opening 302 for the base plate 301 to enter and exit is opened on the side wall of the recycling bin 2 between the two slide rails 3. The base plate 301 can be pushed and pulled outward along the two slide rails 3 towards the strip-shaped opening 302 under the push and pull of an external drive cylinder. The base plate 301 no longer supports the compacted waste block. Relying on its own weight, the material falls downward into the receiving cavity. The operator can open the hinged door 206 on the side of the recycling box 2 to remove the compressed waste block as a whole and transfer it to the subsequent processing. After the waste has fallen, the bottom plate 301 slides back to reset and closes the support position again. The equipment then enters the negative pressure suction and storage state again. The bottom four corners of the recycling box 2 are all equipped with casters 4, which enables the entire recycling mechanism to move freely and can be flexibly aligned and quickly installed according to the position of the hot stamping machine.
[0017] Furthermore, such as Figure 1As shown, the negative pressure assembly includes a main conveying pipe 5 and a negative pressure fan 503. The discharge end of the main conveying pipe 5 is locked to one side of the recycling box 2 and communicates with the compression chamber. The main conveying pipe 5 is arranged around the perimeter of the hot stamping machine workbench 1. The main conveying pipe 5 is connected to multiple branch pipes 501, and each branch pipe 501 is equipped with a dust suction nozzle 502 at its end. The dust suction nozzles 502 face the waste spill area on the surface of the hot stamping machine workbench 1. The negative pressure fan 503 is fixedly installed on the top of the gantry frame 201. The air inlet pipe of the negative pressure fan 503 is connected to the discharge end of the main conveying pipe 5. The main body of the main conveying pipe 5, the air inlet pipe of the negative pressure fan 503, and the discharge end of the main conveying pipe 5 form a Y-shaped structure. When the negative pressure fan 503 installed on the top of the gantry frame 201 is started, the Y-shaped structure is activated. The pipeline structure creates negative pressure inside the main conveying pipe 5. Since the main conveying pipe 5 is arranged around the workbench 1 of the hot stamping machine, and multiple branch pipes 501 are connected in parallel, each branch pipe 501 has a suction nozzle 502 installed at its end corresponding to the waste area on the workbench. Therefore, fragmented waste foil, scraps, and loose rolled waste generated during the hot stamping process are comprehensively collected by the suction nozzles 502, completely preventing waste from accumulating on the workbench and around the equipment. Both the main conveying pipe 5 and the branch pipes 501 use anti-static rigid pipes. This structure effectively prevents the lightweight electroplated aluminum waste foil from being electrostatically attracted and adhering to the pipe walls during high-speed transport, thus avoiding pipe blockage. The negative pressure fan 503... A dust filter is installed at the connection between the air duct and the main conveying pipe 5, and at the connection between the main conveying pipe 5 and the recycling box 2. This can intercept waste particles and impurities, prevent waste from being sucked into the negative pressure fan 503, protect the internal structure, extend the service life of the equipment, and ensure smooth airflow and stable dust collection. The sucked-in waste is evenly sent into the recycling box 2 through the pipeline and finally accumulates on the upper surface of the base plate 301 that is slidably installed on the top of the two slide rails 3. The base plate 301 serves as a support platform to support and accumulate loose waste. Universal wheels 4 are installed at the four corners of the bottom of the recycling box 2. The recycling box 2 can be easily moved as a whole by the universal wheels 4 at the four corners of the bottom, which facilitates the transportation of the whole machine. The recycling box 2 is detachably installed on one side of the workbench and can be disassembled for inspection and maintenance.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
