Description

Technical Field

[0001] This utility model relates to the field of packaging and printing, and in particular to a hot stamping device for packaging boxes. Background Technology

[0002] Hot stamping, also known as electroplated aluminum foil hot stamping, is a printing technique that uses heat to transfer the metallic layer of electroplated aluminum foil onto the surface of a substrate, creating a metallic effect. It is widely used in decorative processing of printed materials, packaging, and fabrics. The core material, electroplated aluminum foil, consists of a polyester film substrate, a release layer, a dyed layer, an aluminum-plated layer, and an adhesive layer. The transfer of graphics is achieved by activating the adhesive layer with heat.

[0003] For example, patent document CN222845020U discloses a pneumatic hot stamping device for packaging boxes. When in use, the packaging box is placed at one end of the conveyor belt and driven to the appropriate position by the conveyor belt. The telescopic cylinder controls the telescopic rod to drive downward, so that the hot stamping mold presses down on the gold foil, so that the gold foil is stamped on the packaging box, completing the hot stamping process of the packaging box. The finished product is sent into the collection tank in the collection bucket by the conveyor belt.

[0004] For mobile phone packaging boxes or similar boxes, since the boxes are hollow, the opening of the box is usually facing down during hot stamping, and the box is placed on a support block. Then the hot stamping mold presses down. Because of the support block, the box will not dent or deform inward. However, these boxes are usually loaded and unloaded manually, which is labor-intensive and inefficient. While the hot stamping device mentioned above can reduce manual loading and unloading, it cannot support the box and is prone to deformation. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-9 As shown, a hot stamping device for packaging boxes includes a base 1, with a hot stamping machine body 2 mounted on top of the base 1. The hot stamping machine body 2 is equipped with a hot stamping mechanism and a winding / unwinding mechanism. The hot stamping mechanism includes a cylinder 201, a connecting frame 202, and a hot stamping heating die 203. The cylinder 201 is mounted on the hot stamping machine body 2, the connecting frame 202 is fixedly connected to the bottom of the output end of the cylinder 201, and the hot stamping heating die 203 is fixedly connected to the bottom of the connecting frame 202. The cylinder 201 drives the connecting frame 202 to move downwards, causing the connecting frame 202 to move... The hot stamping heating mold 203 moves down, heats and presses down the electroplated aluminum foil to perform the hot stamping operation. The unwinding and winding mechanism includes an unwinding assembly 204, a winding assembly 205 and a guide roller assembly 206 installed on the hot stamping machine body 2. The unwinding assembly 204 and the winding assembly 205 are arranged on both sides of the hot stamping mechanism. There are two sets of winding assemblies 205 arranged on both sides of the hot stamping mechanism. The electroplated aluminum foil is wound from the unwinding assembly 204 and guided by the guide roller assemblies 206 on both sides onto the winding assembly 205.

[0030] A support base 3 is bolted to the top of the base 1. A conveying mechanism is installed on the top of the support base 3. The conveying mechanism includes two front-to-back baffles 401, which are slidably connected to the top of the support base 3. Specifically, a groove is provided on the top of the support base 3, and the baffles 401 slide in the groove. The groove limits and guides the baffles 401. A telescopic shaft is rotatably connected between the baffles 401. Two front-to-back conveyor belts 402 are fitted on the telescopic shaft. A conveyor motor 403 for driving the telescopic shaft is fixedly connected to the baffles 401. The telescopic shaft includes a sleeve shaft 404 and an insert shaft 405. The two conveyor belts 402 are respectively fitted on the sleeve shaft 404 and the insert shaft 405. The insert shaft 405 is inserted into the sleeve shaft 404. A protrusion 406 is fixed on the surface of the insert shaft 405. A groove is provided on the inner wall of the sleeve shaft 404. The groove that mates with the protrusion 406, the output end of the conveyor motor 403 is fixedly connected to a sleeve shaft 404. The cooperation between the protrusion 406 and the groove allows the insert shaft 405 and the protrusion 406 to rotate synchronously. When the distance between the two baffles 401 changes, the insert shaft 405 and the protrusion 406 move relative to each other while ensuring normal power transmission. During hot stamping, the packaging box 7 is placed with its opening facing down on the two conveyor belts 402. The baffles 401 restrict the forward and backward movement of the packaging box 7. The conveyor motor 403 drives the conveyor belt 402 to rotate through the telescopic shaft. The conveyor belt 402 moves the packaging box 7 to the bottom of the hot stamping heating mold 203. The hot stamping heating mold 203 moves down to perform hot stamping. After hot stamping is completed, the conveyor belt 402 sends the packaging box 7 out, realizing automatic unloading and continuous production.

[0031] The base 1 is equipped with an adjustment mechanism for adjusting the distance between the two baffles 401 and a positioning support mechanism. The positioning support mechanism includes a pressure seat 601, which is located between the two conveyor belts 402. Two racks 602 are slidably connected inside the pressure seat 601. Push plates 603 are fixedly connected to the ends of the two racks 602 that are far apart from each other. A distance sensor 604 is fixed on the push plate 603. A gear 605 meshes between the two racks 602. The positioning support mechanism includes a power component for driving the gear 605 to rotate and adjusting the height of the pressure seat 601. When the packaging box 7 moves to the lower position of the hot stamping heating mold 203, the packaging box 7 is located above the pressure seat 601. The pressure seat 601 moves up into the interior of the packaging box 7 and contacts the inner top wall of the packaging box 7. This can support the packaging box 7 and prevent the hot stamping heating mold 203 from deforming the packaging box 7.

[0032] The power assembly includes an electric telescopic rod 608, which is fixedly connected to the top of the base 1. A lifting plate 607 is fixedly connected to the top of the telescopic end of the electric telescopic rod 608. A positioning motor 606 is fixedly connected to the top of the lifting plate 607. A pressure seat 601 is fixedly connected to the top of the positioning motor 606. The output shaft of the positioning motor 606 extends into the pressure seat 601 and is fixedly connected to a gear 605. The positioning motor 606 drives the gear 605 to rotate, and the gear 605 drives two racks 602 to move. The racks 602 drive the push plates 603 to move closer to the inner walls of both sides of the packaging box 7. When both push plates 603 are in contact with the inner walls of the packaging box 7, the distance sensor 604 transmits a signal to stop the positioning motor 606. In this way, the two push plates 603 can be used to center and position the packaging box 7 to ensure the accuracy of the hot stamping position. The distance sensor 604 can prevent the racks 602 from moving too far and damaging the packaging box 7.

[0033] The adjustment mechanism includes two support plates 501 arranged front and rear. The support plates 501 are connected to the top of the base 1 by screws. A bidirectional lead screw 502 is connected to the support plate 501 by bearings. Two sliders 503 are threaded onto the bidirectional lead screw 502. The two sliders 503 are fixedly connected to the bottom of the two baffles 401 respectively. A handwheel 504 is fixedly connected to the front end of the bidirectional lead screw 502. By rotating the bidirectional lead screw 502 through the handwheel 504, the bidirectional lead screw 502 drives the two sliders 503 to move closer or further apart. The sliders 503 drive the baffles 401 to move, thereby adjusting the distance between the two baffles 401, and thus adjusting the distance between the two conveyor belts 402. This can accommodate packaging boxes 7 of different sizes and improve versatility.

[0034] Working principle: In use, the packaging box 7 is placed with its opening facing down on the conveyor belt 402. The front and rear baffles 401 restrict the forward and backward movement of the packaging box 7. The conveyor motor 403 drives the sleeve shaft 404 to rotate. The sleeve shaft 404, through the protrusion 406, drives the insertion shaft 405 to rotate synchronously. The sleeve shaft 404 and the insertion shaft 405 drive the conveyor belt 402 to rotate, which delivers the packaging box 7 to below the hot stamping heating mold 203. Then, the conveyor belt 402 stops, and the electric telescopic rod 608 drives the lifting plate 607 to move upward. The lifting plate 607 drives the positioning motor 606 to move upward, and the positioning motor 606 drives the pressure seat 601 to move upward and enter the interior of the packaging box 7 (e.g., ...). Figure 9(As shown), then the positioning motor 606 drives the gear 605 to rotate, the gear 605 drives the two racks 602 to move, and the racks 602 drive the push plates 603 to approach the inner walls of both sides of the packaging box 7. When both push plates 603 are in contact with the inner walls of the packaging box 7, the distance sensor 604 transmits a signal to stop the positioning motor 606. In this way, the two push plates 603 can be used to center and position the packaging box 7 to ensure the accuracy of the hot stamping position. The distance sensor 604 can prevent the racks 602 from moving too far and damaging the packaging box 7. Then, the cylinder 201 drives the hot stamping heating mold 203 to move down for hot stamping. After hot stamping is completed, the hot stamping heating mold 203 moves up, the racks 602 retract into the pressure seat 601, the electric telescopic rod 608 retracts to move the pressure seat 601 down, and the conveyor belt 402 continues to drive the packaging box 7 to move for unloading.

[0035] For packaging boxes 7 of different sizes, the double-acting screw 502 is rotated by the handwheel 504. The double-acting screw 502 drives the two sliders 503 to move closer or further apart. The sliders 503 drive the baffles 401 to move, thereby adjusting the distance between the two baffles 401 and thus adjusting the distance between the two conveyor belts 402. This can adapt to packaging boxes 7 of different sizes and improve versatility.

Apart from that, the electronic components and control modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

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.
