Description

Technical Field

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

[0002] A hot stamping machine is a professional piece of equipment used to perform hot stamping. Its core function is to transfer metal foil, such as gold foil, silver foil or other colored metal foil, onto the surface of various substrates through heat pressing, forming patterns, text or decorative effects with a metallic luster.

[0003] Currently, most hot stamping machines utilize a step-by-step structure to control the downward pressure of the rubber rollers, transferring a thin metal film onto the substrate surface through heating and pressure to achieve pattern hot stamping. However, in existing technologies, the method of driving the rubber rollers downward pressure typically involves setting drive components (such as electric push rods, cylinders, etc.) on both sides to achieve the up-and-down movement of the rollers. While this method can achieve pattern hot stamping, in practical applications, due to factors such as differences in line length and long-term use, there may be a time difference in the signal reception of each drive component, resulting in uneven force on both ends of the rubber roller, leading to poor synchronization and consequently affecting the quality of the pattern hot stamping. Utility Model Content

[0004] The main purpose of this utility model is to provide a step-by-step structure for a hot stamping machine, which improves the synchronization of the step-by-step structure and ensures the stability of the hot stamping pattern quality.

[0005] The technical solution of this utility model is as follows:

[0006] A hot stamping machine step structure includes a rubber roller and a frame. The rubber roller is disposed inside the frame. The machine also includes swing blocks disposed on both sides of the rubber roller. The rubber roller is rotatably connected to one side of the swing blocks, and each swing block is rotatably connected to the inner wall of the frame.

[0007] It also includes a linkage transmission structure that enables the two swing blocks on both sides to simultaneously drive the rubber roller up and down, and a drive component that drives the linkage transmission structure.

[0008] In one possible implementation, the linkage transmission structure includes a rotating block, a swing arm, and a transmission rod;

[0009] One end of the rotating block is fixedly connected to the output shaft of the drive component, and the other end away from the drive component is rotatably connected to the swing arm. The end of the swing arm away from the rotating block is rotatably connected to the transmission rod. Both ends of the transmission rod are respectively provided with transmission components connecting the side of each swing block away from the rubber roller.

[0010] In one possible implementation, the transmission assembly includes a fixed block and a first transmission block;

[0011] The fixing block is fixedly connected to the inner wall of the frame. The fixing block has an installation groove on the side away from the ground. One end of the first transmission block is rotatably connected to the installation groove. The side of the first transmission block away from the installation groove and away from the driving component is rotatably connected to the transmission rod. The side of the first transmission block away from the ground and facing the driving component is rotatably connected to the second transmission block. The side of the second transmission block away from the first transmission block is rotatably connected to the side of the swing block away from the rubber roller.

[0012] In one possible implementation, the transmission assembly includes a guide rail and a sliding block. The guide rail is disposed on the inner wall of the frame, and the sliding block is slidably connected to the guide rail. The end of the second transmission block away from the ground is rotatably connected to the sliding block, and the end of the sliding block away from the second transmission block is rotatably connected to the side of the swing block away from the rubber roller.

[0013] In one possible implementation, the inner walls on both sides of the frame are threaded with fixing bolts on the side near the swing block, and a fixing cylinder is fixedly connected to the outer surface of the fixing bolts. The swing block is provided with a rolling bearing, which is disposed between the rubber roller and the second transmission block. The fixing cylinder is fixedly connected to the inner ring of the rolling bearing.

[0014] In one possible implementation, the transmission assembly includes a damping cylinder, the telescopic rod of which is rotatably connected to a swing block, and the side of the damping cylinder away from the telescopic rod is rotatably connected to a sliding block.

[0015] In one possible implementation, a guide rail mounting base is fixedly connected to the inner wall of the frame, and the guide rail is detachably connected to the guide rail mounting base.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] After the drive unit is activated, its output shaft drives the rotating block, causing the swing arm to swing, which in turn drives the transmission components on both sides of the transmission rod to move. The transmission rod drives the first transmission block to rotate in the mounting slot, causing the second transmission block to drive the sliding block to slide up and down along the linear trajectory of the guide rail. At the same time, the sliding block drives the damping cylinder, causing the swing block to move up and down. The swing block rotates and connects to the rubber roller, causing the rubber roller to rise and press down, realizing the step-by-step action of the hot stamping machine.

[0018] By incorporating swing blocks and transmission components on both sides of the rubber roller, and combining this with a drive unit and linkage transmission structure, a single drive unit can simultaneously drive both sides of the rubber roller up and down via the linkage transmission structure. This not only reduces the cost of the drive source required for the equipment but also improves the synchronization and accuracy of the rubber roller's step-by-step movement, enabling precise location of the pressing point. Simultaneously, the drive unit responds quickly, and the multi-link transmission has low response delay; the combination of these two features allows for rapid start-up and stop of the rubber roller and step-by-step switching, thereby improving production efficiency. Furthermore, through cooperation with a damping cylinder, the downward pressing action of the rubber roller is more stable, further enhancing the stability of the equipment.

[0029] 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

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-7 As shown, this embodiment proposes a step-by-step structure for a hot stamping machine, which includes a rubber roller 1 and a frame 2. The rubber roller 1 is located inside the frame 2, and the frame 2 provides a basic load-bearing structure for the various components of this embodiment.

[0032] A swing block 3 is provided on each side of the rubber roller 1, and the rubber roller 1 is rotatably connected to one side of the swing block 3. Simultaneously, each swing block 3 is rotatably connected to the inner wall of the frame 2, forming a lever structure with the connection point between the swing block 3 and the frame 2 as the fulcrum. This structure converts the rotation of the swing block 3 into the up-and-down movement of the rubber roller 1. Furthermore, a linkage transmission structure 4 is provided to simultaneously drive the rubber roller 1 up and down via the swing blocks 3 on both sides, and a driving component 41 drives the linkage transmission structure 4. The linkage transmission structure 4 achieves simultaneous rise and fall and consistent swing angles of the swing blocks 3 on both sides through mechanical linkage, further ensuring the synchronization rate of the rubber roller 1 during its up-and-down movement. Through the cooperation of the individual driving component 41 and the linkage transmission structure 4, the possibility of skewness caused by asynchronous movement on both sides is reduced, improving the hot stamping pattern quality and synchronization rate of this embodiment.

[0033] In this embodiment, the drive component 41 is preferably a J4 series servo motor, which has the advantages of ±0.01mm positioning accuracy, precise control of the swing angle of the linkage transmission structure 4, and ensuring synchronous movement of the swing blocks on both sides. It also supports high-speed response (response frequency up to 2kHz), quickly adapting to the dynamic needs of the up-and-down movement of the rubber roller 1. Furthermore, smooth speed adjustment can be achieved through pulse commands, reducing the skewing of the rubber roller 1 caused by mechanical impact.

[0034] like Figure 4As shown, both sides of the inner wall of the frame 2, near the swing block 3, are threaded with fixing bolts 61. The swing block 3 is equipped with a rolling bearing 63, and a fixing cylinder 62 is fixedly connected to the outer surface of the fixing bolts 61, providing a suitable mating body for the rolling bearing 63. The rolling bearing 63 is positioned between the rubber roller 1 and the second transmission block 53, and the fixing cylinder 62 is fixedly connected to the inner ring of the rolling bearing 63, allowing the swing block 3 to rotate around the fixing cylinder 62 and swing normally at both ends. The rolling bearing 63 reduces frictional loss between components, not only improving the flexibility of the swing block 3 during swing but also extending the service life of each component.

[0035] like Figure 3 As shown, the linkage transmission structure 4 in this embodiment includes a rotating block 42, a swing arm 43, and a transmission rod 44. One end of the rotating block 42 is fixedly connected to the output shaft of the drive component 41, and the other end away from the drive component 41 is rotatably connected to the swing arm 43. The rotating block 42 can initially convert the rotational motion of the drive component 41 and transmit the rotational motion of the drive component 41 to the swing arm 43, reducing the impact caused by the direct rotational connection of the drive component 41 to the swing arm 43 and reducing frictional loss during transmission. The end of the swing arm 43 away from the rotating block 42 is rotatably connected to the transmission rod 44, and the force is transmitted to the transmission rod 44 through the rotational connection. At the same time, the length of the swing arm 43 can be designed according to the actual transmission ratio requirements, which will not be elaborated in this embodiment.

[0036] The two ends of the transmission rod 44 are respectively provided with transmission components 5 that connect the swing blocks 3 to the side away from the rubber roller 1, so as to ensure that the power of the drive component 41 can be evenly distributed to the transmission components 5 on both sides, ensuring the synchronicity of the movement of the swing blocks 3 on both sides, and avoiding the tilting of the rubber roller 1 caused by excessive force on one side or movement lag.

[0037] The transmission assembly 5 includes a fixed block 51 and a first transmission block 52. The fixed block 51 is fixedly connected to the inner wall of the frame 2, providing a stable reference point for the transmission assembly 5. The fixed block 51 has a mounting groove 511 on the side away from the ground, and one end of the first transmission block 52 is limited to the mounting groove 511 and rotatably connected to it. The side of the first transmission block 52 away from the mounting groove 511 and away from the drive component 41 is rotatably connected to the transmission rod 44. While avoiding interference with other components, it converts the force transmitted by the transmission rod 44 into swinging motion, allowing the first transmission block 52 to swing in the mounting groove 511.

[0038] The first transmission block 52 is rotatably connected to the second transmission block 53 at the end away from the ground and facing the drive member 41. The side of the second transmission block 53 away from the first transmission block 52 is rotatably connected to the side of the swing block 3 away from the rubber roller 1. The power of the drive member 41 is transmitted to the swing block 3 step by step through each transmission block, realizing the synchronous up and down movement of the rubber roller 1.

[0039] In this embodiment, the transmission component 5 also includes a guide rail 54 and a sliding block 55, further improving the stability of the transmission component 5. The guide rail 54 is located on the inner wall of the frame 2, and the sliding block 55 is slidably connected to the guide rail 54. The end of the second transmission block 53 away from the ground is rotatably connected to the sliding block 55, transmitting the force of the second transmission block 53 to the sliding block 55, causing the sliding block 55 to move linearly along the guide rail 54, thus converting the oscillating motion into linear motion. The end of the sliding block 55 away from the second transmission block 53 is rotatably connected to the side of the oscillating block 3 away from the rubber roller 1, allowing the oscillating block 3 to move up and down linearly synchronously and stably along the guide rail 54 with the sliding block 55, reducing the shaking during equipment operation and improving the stability and the quality of the hot stamping pattern in this embodiment.

[0040] In this embodiment, all rotating connections utilize bearings. This design allows for flexible rotation, meeting the rotational requirements of each transmission component and ensuring efficient power transmission to the rubber roller 1. Simultaneously, the standardized structure of the bearings guarantees rotational accuracy, stably controlling the movement trajectory of each transmission component, reducing transmission deviations caused by excessive clearance or uneven friction, ensuring synchronized movement of the two swing blocks 3, and improving the consistency of the rubber roller 1's movement. Furthermore, it enhances the structural strength and durability of the connection points, extending the equipment's service life.

[0041] In this embodiment, the transmission assembly 5 includes a shock-absorbing cylinder 57, which provides a buffering effect for the various mechanical components of the transmission assembly 5. The shock-absorbing cylinder 57 can absorb the impact force during the movement through the gas compression characteristics, thereby improving the stability of the transmission assembly 5. The telescopic rod of the shock-absorbing cylinder 57 is rotatably connected to the swing block 3, and the side of the shock-absorbing cylinder 57 away from the telescopic rod is rotatably connected to the sliding block 55, so that the buffering force can act on the rubber roller 1 through the swing block 3, reducing the inertial impact during its up-and-down movement, such as the impact force when it comes into contact with the substrate. This reduces the possibility of the hot stamping pattern becoming blurred or misaligned due to vibration of the rubber roller 1, ensuring the stability of the hot stamping pattern quality in this embodiment.

[0042] In this embodiment, a guide rail mounting base 541 is fixedly connected to the inner wall of the frame 2, providing a stable support foundation for the guide rail 54 and reducing the possibility of the guide rail 54 shaking under force during equipment operation. The guide rail 54 is detachably connected to the guide rail mounting base 541 by bolts. When the guide rail 54 needs maintenance, maintenance personnel can quickly replace and maintain it by removing the bolts, improving the convenience and speed of maintenance.

[0043] The working process of this embodiment is as follows:

[0044] 1. After the operator sends a start signal to the equipment, the drive unit 41 starts, and its output shaft drives the rotating block 42 to rotate clockwise. The rotating block 42 converts the rotational motion and transmits it to the swing arm 43, causing the swing arm 43 to swing to the left, thereby driving the transmission rod 44 and the transmission components 5 connected to both sides to move to the left.

[0045] The end of the first transmission block 52 away from the mounting groove 511 is swung to the left by the force of the transmission rod 44, which drives the end of the second transmission block 53 close to the first transmission block 52 to the left at the same time. The sliding block 55 is slid down along the guide rail 54 by the force of the second transmission block 53 to the left, which causes the damping cylinder 57 to drive the end of the swing block 3 away from the rubber roller 1 to rotate downward. At the same time, the swing block 3 will rotate around the fixed cylinder 62, and cause the rubber roller 1 on the other side of the swing block 3 to rotate upward, thereby realizing the lifting of the rubber roller 1.

[0046] 2. After the rubber roller is lifted, the drive component 41 continues to drive the rotating block 42 to rotate clockwise. At this time, the swing arm 43 swings back to the right, thereby driving the transmission rod 44 and the transmission components 5 connected to both sides to move to the right.

[0047] The end of the first transmission block 52 away from the mounting groove 511 is swung to the right by the force of the transmission rod 44, which drives the end of the second transmission block 53 close to the first transmission block 52 to also swung to the right. The sliding block 55 is slid upward along the guide rail 54 by the force of the second transmission block 53 swung to the right, which causes the damping cylinder 57 to drive the end of the swing block 3 away from the rubber roller 1 to rotate upward. At the same time, the swing block 3 will rotate around the fixed cylinder 62, and cause the rubber roller 1 on the other side of the swing block 3 to rotate downward, thereby realizing the downward pressure of the rubber roller 1.

[0048] 3. After the hot stamping process is completed, the operator sends a stop signal to the equipment. Once the equipment has completely stopped, maintenance can be performed. Alternatively, the operator can input a control program into the drive unit 41 (i.e., the servo motor), causing the output of the drive unit 41 to drive the rotating block 42 in both forward and reverse directions, thereby pressing down and lifting the rubber roller 1. Both methods can achieve the pressing down and lifting of the rubber roller 1. The operator can choose the appropriate method based on the actual situation; this embodiment does not specifically limit this method.
