Description

Technical Field

[0001] This utility model relates to a hot stamping machine, specifically, to a hot stamping machine that facilitates feeding and rewinding. Background Technology

[0002] Hot stamping refers to the process of hot stamping electroplated aluminum foil onto the surface of a substrate under certain temperature and pressure. A hot stamping machine is the equipment used to complete this process. During hot stamping, materials are typically conveyed via unwinding and rewinding devices. The hot stamping machine compresses and heats the material, causing slight deformation. Furthermore, differences in friction between the unwinding and rewinding rollers and the material cylinder during the unwinding and rewinding process can cause the cylinder to rotate or move, leading to material movement or loosening. These unavoidable factors cause the material's movement path to deviate during unwinding and rewinding, preventing it from accurately centering within the effective working area of ​​the hot stamping module. This results in uneven heating at the edges, reducing the hot stamping effect. When the material's movement path deviates, operators need to frequently stop the machine to adjust it, reducing the machine's efficiency and increasing operator workload. Therefore, we propose a hot stamping machine with an easy-to-feed and rewind mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a hot stamping machine that facilitates feeding and rewinding, in order to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, the present invention aims to provide a hot stamping machine that facilitates feeding and rewinding. The machine includes a base, a mounting frame on top of the base, and a lifting assembly on the upper side of the base to drive the mounting frame up and down. A hot stamping top plate is fixedly connected to the lower side of the mounting frame, and a hot stamping bottom plate is fixedly connected to the upper side of the base. The mounting frame drives the hot stamping top plate downwards, and the hot stamping top plate and hot stamping bottom plate cooperate to hot stamp the material. The mounting frame is equipped with a winding and unwinding mechanism for unwinding and rewinding the material, and for adjusting the tension and movement path of the material. The winding and unwinding mechanism includes a mounting rod, with an unwinding assembly and a winding assembly at each end of the mounting rod, and adjustment components near both ends of the mounting rod.

[0005] As a further improvement to this technical solution, the winding and unwinding mechanism also includes two first electric telescopic rods symmetrically and fixedly connected to the mounting frame, wherein the piston rod end of the first electric telescopic rod is fixedly connected to the mounting rod.

[0006] As a further improvement to this technical solution, the piston rod of the first electric telescopic rod extends and retracts, driving the mounting rod to move. The mounting rod then drives the unwinding assembly and the winding assembly to move, thereby changing the material's movement path.

[0007] As a further improvement to this technical solution, the adjustment assembly includes a movable frame slidably connected to the mounting rod, and an adjustment rod is slidably connected inside the movable frame, the adjustment rod moving up and down in the vertical direction.

[0008] As a further improvement to this technical solution, the lower end of the adjusting rod passes through the movable frame and extends outwards, and a guide roller is rotatably connected to the bottom of the movable frame near the mounting rod. The guide roller is used to guide and change the movement path of the material.

[0009] As a further improvement to this technical solution, the guide roller is located below the hot stamping top plate, and the material passes between the hot stamping top plate and the hot stamping bottom plate.

[0010] As a further improvement to this technical solution, the adjustment assembly also includes a second electric telescopic rod fixedly connected to the side of the mounting rod away from the mounting frame. The piston rod end of the second electric telescopic rod is fixedly connected to the movable frame. The extension and retraction of the piston rod of the second electric telescopic rod drives the movable frame and the adjustment rod to move along the axial direction of the mounting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This hot stamping machine, which facilitates feeding and rewinding, uses a second electric telescopic rod to extend its piston rod during the hot stamping process. This extension drives the guide roller to move and tension the material, increasing the friction between the material and the guide roller to reduce the probability of deviation. When the material deviates, the piston rod of the first electric telescopic rod extends and retracts, moving the material as a whole via the mounting rod. This automatically corrects the material's movement path, ensuring that the material is always precisely aligned with the center area of ​​the hot stamping plate. This allows the hot stamping machine to heat the material evenly and comprehensively, improving the hot stamping effect. Furthermore, it eliminates the need for frequent machine stops to adjust the material's movement path, thus increasing the overall efficiency of the hot stamping machine. Attached Figure Description

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example Please see Figure 1 - Figure 5 As shown, the purpose of this embodiment is to provide a hot stamping machine that facilitates feeding and winding, including a base 1, a mounting frame 12 above the base 1, and a lifting assembly 11 for driving the mounting frame 12 to move up and down on the upper side of the base 1. The lifting assembly 11 includes a mounting shell fixedly connected to the upper side of the base 1, an adjusting screw rotatably connected inside the mounting shell, a lifting block connected to the adjusting screw via a screw nut, a third electric telescopic rod fixedly connected to the lifting block, the piston rod end of the third electric telescopic rod passing through the lifting block and fixedly connected to the upper side of the mounting frame 12, the piston rod of the third electric telescopic rod extending and retracting to drive the mounting frame 12 to move up or down. The lifting assembly 11 is prior art, and this solution does not improve upon it, so it will not be described here. A hot stamping top plate is fixedly connected to the lower side of the mounting frame 12, and a hot stamping bottom plate is fixedly connected to the upper side of the base 1. The mounting frame 12 drives the hot stamping top plate to move down, and the hot stamping top plate and the hot stamping bottom plate cooperate to hot stamp the material. A winding and unwinding mechanism 2 is provided on the mounting frame 12. The winding and unwinding mechanism 2 is used to unwind and wind up the material, and to adjust the tension and movement path of the material. The winding and unwinding mechanism 2 includes a mounting rod 21. Two limiting rods are fixedly connected to one side of the mounting frame 12 near the mounting rod 21. The mounting rod 21 is slidably connected to the two limiting rods. The limiting rods restrict the movement path of the mounting rod 21, so that the mounting rod 21 moves along the axis of the limiting rods. An unwinding assembly 23 and a winding assembly 24 are respectively provided at both ends of the mounting rod 21. The unwinding assembly 23 is used to unwind the material, and the winding assembly 24 is used to wind up the hot-stamped material. Adjustment components are provided on both ends of the mounting rod 21. The two adjustment components cooperate with each other to adjust the tension of the material conveying. The unwinding assembly 23 includes an unwinding roller rotatably connected to one end of the mounting rod 21, a first motor driving the unwinding roller to rotate, two synchronous pulleys, and a synchronous belt driving the two synchronous pulleys. The rotation of the unwinding roller unwinds the material. The winding assembly 24 includes a winding roller rotatably connected to the other end of the mounting rod 21, a second motor driving the winding roller to rotate, and a reducer. The rotation of the winding roller winds up the material. The unwinding assembly 23 and the winding assembly 24 are existing technologies, and this solution does not improve upon them. They will not be described here. Both the first motor and the second motor are controlled by an external control device. The control device is existing technology, and this solution does not improve upon it. They will not be described here.

[0016] refer to Figure 3 - Figure 5 The unwinding and rewinding mechanism 2 also includes two first electric telescopic rods 22 symmetrically fixedly connected to the mounting frame 12. The piston rod end of the first electric telescopic rod 22 is fixedly connected to the mounting rod 21. During the hot stamping process, in order to observe whether the material's movement path has deviated in time, two baffles can be installed on the upper side of the base 1. The two baffles are located on both sides of the material, and the distance between the two baffles is adapted to the size of the effective working area of ​​the hot stamping top plate. The operator can judge whether the material's movement path has deviated by observing the distance between the edge of the material and the baffle and whether the two are in contact. When the material's movement path deviates, the piston rod of the first electric telescopic rod 22 extends and retracts, causing the mounting rod 21 to move. The mounting rod 21 causes the unwinding assembly 23 and the rewinding assembly 24 to move to change the material's movement path, ensuring that the material's movement path is located in the center of the effective working area of ​​the hot stamping top plate, reducing the probability of uneven heating of the material, and improving its hot stamping effect.

[0017] refer to Figure 6The adjustment assembly includes a movable frame 25 slidably connected to the mounting rod 21. An adjustment rod 26 is slidably connected inside the movable frame 25. The adjustment rod 26 moves up and down in the vertical direction. The lower end of the adjustment rod 26 passes through the movable frame 25 and extends outward. A guide roller 27 is rotatably connected to the bottom of the movable frame 25 near the mounting rod 21. The guide roller 27 is used to guide and change the movement path of the material. The guide roller 27 is located below the hot stamping top plate. The material passes between the hot stamping top plate and the hot stamping bottom plate. The adjustment assembly also includes a second electric telescopic rod 28 fixedly connected to the mounting rod 21 on the side away from the mounting frame 12. The piston rods of the two second electric telescopic rods 28 extend in opposite directions. The piston rod ends of the second electric telescopic rods 28 are fixedly connected to the movable frame 25. The extension and retraction of the piston rods of the second electric telescopic rods 28 drive the movable frame 25 and the adjustment rod 26 to move along the axial direction of the mounting rod 21. During the hot stamping process, the piston rods of the two second electric telescopic rods 28 extend, driving the two guide rollers 27 to move away from each other. The guide rollers 27 compress the material during the movement to increase the tension of the material, ensure that the material is in contact with the surface of the guide rollers 27, and increase the friction between the two, reducing the probability of the material deviating during the conveying process. When the material deviates, the piston rods of the two second electric telescopic rods 28 retract, driving the two guide rollers 27 to move closer to each other, making the material loose, reducing the friction between the material and the guide rollers 27, and making it easier for the staff to adjust the movement path of the material.

[0018] When using this device: In the initial state, the hot stamping top plate and the hot stamping bottom plate are located far apart from each other. The worker installs the material roll on the unwinding roller, and then pulls one end of the material to pass through the underside of the guide roller 27 and the gap between the hot stamping top plate and the hot stamping bottom plate, and fixes one end of the material on the surface of the take-up roller. The piston rod of the second electric telescopic rod 28 extends and drives the guide roller 27 to move away from the mounting frame 12, so that it tensions the material. The piston rod of the first electric telescopic rod 22 extends and retracts, driving the mounting rod 21 and the material to move to change their movement path, so that the material is located in the center of the effective working area of ​​the hot stamping top plate. Subsequently, the unwinding roller rotates to unwind the material, while the rewinding roller rotates to rewind the material. After the material has moved a certain distance, the mounting frame 12 drives the hot stamping top plate and the material to move downwards synchronously, and the hot stamping top plate and the hot stamping bottom plate heat and hot stamp the material. After the material is hot-stamped, the mounting frame 12 moves the hot-stamping top plate and the material upward away from the hot-stamping bottom plate. The unwinding roller and the rewinding roller rotate synchronously to move the material and perform hot-stamping on subsequent materials.
