Description

Technical Field

[0001] This utility model relates to the field of hot stamping machine technology, and in particular to a hot stamping machine. Background Technology

[0002] A hot stamping machine is generally a device used to hot stamp metal foil (such as gold foil, silver foil, colored foil, etc.) or special coatings on the surface of materials such as paper, plastic, leather, and textiles. Therefore, it is usually equipped with a winding mechanism for winding up the metal foil.

[0003] Currently, traditional winding mechanisms typically use fixed winding rollers, which cause the winding and hot stamping material (metal foil) to always be wound in the same position during the winding process. This results in each roll of material being stacked in the same position, causing the interlayer pressure of the metal foil on the winding roller to gradually accumulate during the winding process, while the pressure in other areas is smaller. This leads to a severe imbalance in the tension of the metal foil, causing it to wrinkle. Due to the special expansion mechanism of wrinkles, the wrinkles extend towards the unwound areas, ultimately affecting the hot stamping effect of the hot stamping machine. Utility Model Content

[0004] The main purpose of this invention is to provide a hot stamping machine that solves the problem of severe tension imbalance at both ends of the metal foil caused by the metal foil always being wound in the same position during winding.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A hot stamping machine includes a body and a take-up roller, the take-up roller being rotatably connected to the body. The body is provided with a first drive motor for controlling the rotation of the take-up roller. The body is also provided with a moving mechanism for controlling the take-up roller to move along its axial direction. A linkage structure is provided between the output shaft of the first drive motor and the take-up roller.

[0007] Furthermore, the take-up roller includes a take-up roller body, a bearing groove, and a fixed end cap. The bearing groove is formed on the take-up roller body, and the fixed end cap is threadedly connected to the take-up roller body. The diameter of the fixed end cap is larger than the diameter of the bottom of the bearing groove.

[0008] Furthermore, the moving mechanism includes a mechanism base, a second drive motor, a drive screw, and a moving plate. The mechanism base is fixedly connected to the machine body. The drive screw is rotatably connected to the mechanism base and linked with the output shaft of the second drive motor. The moving plate is drive-connected to the drive screw. The take-up roller is rotatably connected to the moving plate and moves with the movement of the moving plate.

[0009] Furthermore, a first bearing is provided between the movable plate and the take-up roller. The movable plate is provided with limiting plates at both ends in the axial direction of the take-up roller. Each limiting plate is fixedly connected to the movable plate, and each limiting plate is provided with a first bearing retaining hole. The diameter of the inner ring of the outer ring of the first bearing is larger than the diameter of the first bearing retaining hole.

[0010] Furthermore, the linkage structure includes a first linkage wheel, a second linkage wheel, and a linkage belt for linking the first linkage wheel and the second linkage wheel. The second linkage wheel is fixedly mounted on the take-up roller, and the first linkage wheel is linked to the output shaft of the first drive motor. The axial length of the first linkage wheel is greater than the bandwidth of the linkage belt.

[0011] Furthermore, both the first and second linkage wheels are synchronous wheels.

[0012] Furthermore, the mechanism base includes a sliding rod, and the sliding rod and the winding roller are evenly distributed around the drive screw, with the moving plate slidably connected to the sliding rod.

[0013] Furthermore, the take-up roller body includes a hollow part and a threaded part. Both ends of the hollow part are provided with connecting parts. The connecting part close to the threaded part is located between the threaded part and the hollow part. The bearing groove is formed on the connecting part.

[0014] Furthermore, the take-up roller is provided with several weight-reduction grooves.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] This utility model's technical solution employs a moving mechanism on the machine body to control the movement of the take-up roller along its axial direction. This allows the take-up roller to move during the take-up process, thereby changing the take-up and winding position of the roll material. This ensures that the roll material (metal foil) is evenly wound on the take-up roller, thus evenly distributing stress and preventing severe tension imbalance at both ends of the metal foil, as well as preventing wrinkling of the metal foil. This guarantees the hot stamping effect of this utility model.

[0017] Meanwhile, in this utility model, a linkage structure is provided between the output shaft of the first drive motor used to drive the take-up roller to rotate. By means of the linkage effect of the linkage structure, the movement of the take-up roller is prevented from interfering with the linkage movement between it and the first drive motor, thus ensuring that the technical solution of this utility model can be implemented.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] like Figure 1As shown, a hot stamping machine mainly includes a machine body 1 and a take-up roller 2. The take-up roller 2 is rotatably connected to the machine body 1. The machine body 1 is provided with a first drive motor 3 for controlling the rotation of the take-up roller 2 and a moving mechanism 4 for controlling the take-up roller 2 to move along its axial direction. That is, with the help of the moving mechanism 4, the take-up roller 2 can move during the winding process, thereby changing the winding and wrapping position of the roll material. In this way, by simply making the take-up roller 2 move repeatedly, the roll material (metal foil) can be evenly wrapped on the take-up roller 2, thereby evenly dispersing stress, avoiding serious tension imbalance on both sides of the metal foil, and avoiding wrinkling of the metal foil, thus ensuring the hot stamping effect of this embodiment.

[0030] To avoid interference between the movement of the take-up roller 2 and its linkage with the first drive motor 3, a linkage structure 5 is provided between the output shaft of the first drive motor 3 and the take-up roller 2. That is, the existence of the linkage structure 5 and the linkage effect are used to ensure that this embodiment can be implemented normally.

[0031] like Figure 1 , Figure 4 As shown, the moving mechanism 4 mainly includes a mechanism base 41, a second drive motor 42, a drive screw 43, and a moving plate 44. The mechanism base 41 is fixedly connected to the machine body 1, enabling the mechanism base 41 to serve as the main carrier of the moving mechanism 4. The drive screw 43 is rotatably connected to the mechanism base 41 and linked with the output shaft of the second drive motor 42. Correspondingly, the mechanism base 41 should be equipped with a motor mount and other fixing components for fixing the second drive motor 42 to ensure that the second drive motor 42 can stably provide driving force. The moving plate 44 is tractively connected to the drive screw 43. The take-up roller 2 is rotatably connected to the moving plate 44 and moves with the movement of the moving plate 44. That is, in this embodiment, the moving mechanism 4 uses screw transmission to control the movement of the take-up roller 2, ensuring that the moving mechanism 4 has sufficient force to drive the take-up roller 2 to move.

[0032] In this embodiment, the second drive motor 42 is preferably a brushless DC motor or other motor capable of frequent forward and reverse rotation, thereby effectively adapting to the reciprocating sliding motion of the take-up roller 2.

[0033] Meanwhile, a first bearing 6 is provided between the moving plate 44 and the take-up roller 2, that is, the take-up roller 2 is located in the inner ring of the first bearing 6, and the moving plate 44 and the outer ring of the first bearing 6 cooperate with each other. By means of the cooperation between the inner and outer rings of the first bearing 6, the friction between the take-up roller 2 and the moving plate 44 can be effectively reduced.

[0034] Similarly, a second bearing and a bearing housing for fixing the second bearing should also be installed between the take-up roller 2 and the machine body 1 to reduce friction between the take-up roller 2 and the machine body 1. Each bearing (the first bearing 6 and the second bearing) should be adjusted according to its installation and mating parts (in terms of specifications). Therefore, the specific structure of each bearing will not be described in this embodiment.

[0035] like Figure 1 , Figures 4-6 As shown, the movable plate 44 is provided with limiting plates 45 at both ends in the axial direction of the take-up roller 2. Each limiting plate 45 is fixedly connected to the movable plate 44, and each limiting plate 45 is provided with a first bearing retaining hole 451. The diameter of the inner ring of the outer ring of the first bearing 6 is larger than the diameter of the first bearing retaining hole 451. That is, the existence of each limiting plate 45 is used to constrain the first bearing 6 and ensure that it can move with the take-up roller 2. Because the first bearing 6 is located closer to the end face of the take-up roller 2, if the first bearing 6 cannot move with the take-up roller 2 and the movable plate 44, it is easy to detach from the take-up roller 2 during the movement of the take-up roller 2, which will damage the stability of the overall structure of this embodiment.

[0036] The mechanism base 41 includes a sliding rod 411. The sliding rod 411 and the take-up roller 2 are evenly distributed around the drive screw 43. The moving plate 44 is slidably connected to the sliding rod 411, thereby effectively ensuring the symmetry between the moving plate 44, the mechanism base 41, and the take-up roller 2, so that the force flow is evenly distributed, and the moving plate 44 is prevented from deforming due to unilateral force during movement, thus ensuring the structural stability of the moving plate 44.

[0037] The take-up roller 2 includes a take-up roller body 21, a bearing groove 22, and a fixed end cap 23. The bearing groove 22 is formed on the take-up roller body 21 to ensure that the take-up roller 2 has an installation point that matches the first bearing 6, so as to realize the installation of the first bearing 6 on the take-up roller 2. The fixed end cap 23 is threadedly connected to the take-up roller body 21. It is worth noting that the bearing groove 22 will form a complete annular groove structure only after the fixed end cap 23 and the take-up roller body 21 are in mutual cooperation. Correspondingly, the diameter of the fixed end cap 23 is larger than the diameter of the bottom of the bearing groove 22, so that the inner ring of the first bearing 6 can move with the take-up roller 2 without maintaining an interference fit with the take-up roller 2, thereby facilitating the disassembly of the take-up roller 2 later. If necessary, several fixed end caps 23 can be provided, that is, the fixing effect of the first bearing 6 can be strengthened by increasing the number of fixed end caps 23.

[0038] Meanwhile, the take-up roller body 21 in this embodiment mainly includes a hollow part 211 and a threaded part 212. The presence of the hollow part 211 can effectively reduce the weight of the take-up roller body 21 itself, thereby effectively reducing the operating load of the moving mechanism 4. The hollow part 211 is used as a carrier for the wound metal foil. The threaded part 212 is used for threaded connection of the fixed end cap 23. Both ends of the hollow part 211 are provided with connecting parts 213. The connecting parts 213 close to the threaded part 212 are located between the threaded part 212 and the hollow part 211. Each connecting part 213 is used to cooperate with each bearing. Correspondingly, the bearing groove 22 is opened on the connecting part 213.

[0039] Furthermore, the take-up roller 2 is provided with several weight-reducing grooves 2111. Each weight-reducing groove 2111 is opened on the hollow part 211, thereby further reducing the weight of the take-up roller 2 itself. The weight-reducing grooves 2111 are distributed circumferentially around the take-up roller 2, and adjacent weight-reducing grooves 2111 are spaced apart in the radial direction of the take-up roller 2. This avoids the presence of each weight-reducing groove 2111 causing a sudden drop in the structural strength of the take-up roller 2, ensuring that the take-up roller 2 can still be used normally as a take-up carrier.

[0040] like Figures 1-3 As shown, the linkage structure 5 in this embodiment includes a first linkage wheel 51, a second linkage wheel 52, and a linkage belt 53 for linking the first linkage wheel 51 and the second linkage wheel 52. The second linkage wheel 52 is fixedly mounted on the take-up roller 2, and the first linkage wheel 51 is linked with the output shaft of the first drive motor 3. That is, in this embodiment, the take-up roller 2 and the output shaft of the first drive motor 3 are linked by belt drive. At the same time, the axial length of the first linkage wheel 51 is greater than the width of the linkage belt 53. That is, when the second linkage wheel 52 moves with the take-up roller 2 and drives the linkage belt 53 to move together, the linkage belt 53 can slide on the first linkage wheel 51, thereby adapting to the position of the moved second linkage wheel 52. This allows the linkage structure 5 to effectively prevent the movement of the take-up roller 2 and the linkage movement between the take-up roller 2 and the first drive motor 3 from interfering with each other.

[0041] Preferably, the connection between the second linkage wheel 52 and the take-up roller 2 is achieved by opening a connecting ring on the end face of the second linkage wheel 52, providing a connecting hole on the connecting ring, starting a fixing hole at a position coaxial with the connecting hole, and then threaded fasteners such as bolts with nuts are threadedly connected between the fixing hole and the connecting hole, thereby ensuring that the two are detachable.

[0042] Both the first linkage wheel 51 and the second linkage wheel 52 are synchronous wheels, and correspondingly, the linkage belt 53 is a synchronous belt. By means of the toothed engagement between the synchronous wheel and the synchronous belt, the movement trajectory and manner of the linkage belt 53 as it moves with the second linkage wheel 52 are constrained. This is to prevent the linkage belt 53 from slipping or folding when it moves along the axial direction of the first linkage wheel 51, thus ensuring the structural stability of the linkage belt 53 itself. In turn, this ensures that the linkage structure 5 can stably link the output shaft of the first drive motor 3 and the take-up roller 2.
