[0001] This utility model relates to the field of printing machinery technology, and in particular to a hot stamping plate replacement mechanism for a hot stamping machine. Background Technology

[0002] Hot stamping machines are widely used in production and processing. Hot stamping plates are one of the important components of hot stamping machines. As processing needs change, different hot stamping plates need to be replaced in a timely manner. Currently, there are many types of hot stamping machines on the market.

[0003] Traditional hot stamping stencils are mostly installed and fixed directly with fastening screws. When operators need to replace the hot stamping stencils, the disassembly and assembly are complicated, which increases the difficulty of operation. Especially for large hot stamping stencils, it is difficult for a single person to accurately control the posture of the stencil, and multiple people are required to adjust it, which further increases the complexity of operation. Utility Model Content

[0004] The purpose of this utility model is to provide a hot stamping plate replacement mechanism for a hot stamping machine, which aims to solve the technical problem of complex replacement and disassembly of existing hot stamping plates.

[0005] A hot stamping plate changing mechanism for a hot stamping machine is provided, including a mounting plate, a hot stamping plate, a support arm assembly, a guide assembly, a clamping block, and a cylinder;

[0006] The guide assembly is located between the mounting plate and the hot stamping plate, and the hot stamping plate is slidably connected to the bottom of the mounting plate along the horizontal direction through the guide assembly;

[0007] The cylinder is mounted on the mounting plate, and one end of the clamping block is connected to the output end of the cylinder, while the other end presses against the hot stamping plate.

[0008] The support arm assembly is located on one side of the mounting plate. The support arm assembly includes a rotating slide that can rotate about an axis perpendicular to the direction of hot stamping plate withdrawal. The rotating slide has a groove for receiving the hot stamping plate.

[0009] Furthermore, the support arm assembly is provided with a support portion that extends along the sliding direction of the hot stamping plate.

[0010] Furthermore, the support arm assembly includes a fixed section and a movable section. The fixed section is fixed to the frame on the side near the mounting plate, and one end of the movable section is rotatably connected to the fixed section. A limit seat is provided on the fixed section.

[0011] Furthermore, a movable stop is provided in the groove, and the stop is connected to the side wall of the rotary slide through an elastic element.

[0012] Furthermore, the end of the stop block facing the groove opening is provided with a rounded chamfer.

[0013] Furthermore, the guide assembly includes a boss and a groove that mates with the boss.

[0014] Furthermore, the groove and the boss slide together, and the boss is a dovetail-shaped boss, while the groove is a dovetail groove that matches the dovetail-shaped boss.

[0015] Furthermore, elastic pads are provided on the contact surface between the clamping block and the hot stamping plate.

[0016] Furthermore, the piston rod of the cylinder moves in a direction perpendicular to the direction in which the hot stamping plate is pulled out.

[0017] Furthermore, it also includes a limiting mechanism, which is located at the end of the guide assembly away from the clamping block.

[0018] When it is necessary to replace the hot stamping plate, the operator uses a pull-out tool to pull the hot stamping plate directly horizontally from under the mounting plate, smoothly removing it from the working position. The removed hot stamping plate is transferred to the support arm assembly, which firmly supports it, completely detaching it from the mounting plate. On the support arm assembly, the hot stamping plate can be rotated or flipped. This action allows the operator to easily adjust the posture of the hot stamping plate for inspection, cleaning, and other maintenance work.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. Simplified assembly and disassembly process: With the precise guidance of the guide component, the hot stamping plate can be smoothly pulled out in the horizontal direction. With the help of the cylinder-driven clamping block, it can be quickly clamped and released without the need for complicated tools and bolts, which greatly simplifies the process and shortens the equipment downtime.

[0021] 2. Quick adjustment of hot stamping plate posture: The rotating slide of the support arm assembly can hold the hot stamping plate that has been pulled out. The operator can easily adjust the posture of the hot stamping plate by rotating the slide, without having to operate in the narrow space inside the equipment. This facilitates the inspection, cleaning and other maintenance work of the hot stamping plate, and improves the convenience of maintenance.

[0022] 3. Enhanced safety: The guide assembly restricts the sliding direction of the hot stamping plate, preventing it from tilting and jamming during pulling, and reducing collision damage between the hot stamping plate and the mounting plate; the support arm assembly firmly supports the hot stamping plate, preventing accidental slippage during disassembly and assembly; the cylinder-driven clamping method ensures reliable positioning of the hot stamping plate during operation, avoiding equipment failure and safety risks caused by loosening, and extending the service life of parts.

[0045] Please refer to Figure 1-6 The hot stamping plate replacement mechanism for the hot stamping machine in this embodiment will now be described.

[0046] Please refer to Figure 1-6This application provides a hot stamping plate replacement mechanism for a hot stamping machine, including a mounting plate 1, a hot stamping plate 2, a support arm assembly 3, a guide assembly 4, a clamping block 5, and a cylinder 6;

[0047] The guide component 4 is located between the mounting plate 1 and the hot stamping plate 2. The hot stamping plate 2 is slidably connected to the bottom of the mounting plate 1 in the horizontal direction through the guide component 4.

[0048] Cylinder 6 is mounted on mounting plate 1, and one end of clamping block 5 is connected to the output end of cylinder 6, while the other end presses against hot stamping plate 2.

[0049] The support arm assembly 3 is disposed on one side of the mounting plate 1. The support arm assembly 3 includes a rotating slide 32, which can rotate around an axis perpendicular to the direction of the hot stamping plate 2 being pulled out. The rotating slide 32 is provided with a groove 321 for receiving the hot stamping plate 2.

[0050] Specifically, the guide component 4 is located between the mounting plate 1 and the hot stamping plate 2, forming a sliding constraint. The hot stamping plate 2 can only slide relative to the mounting plate 1 in the horizontal direction, limiting the pull-out path. The guide component 4 limits the sliding direction to prevent tilting during pull-out. It works in conjunction with the clamping block 5 driven by the cylinder 6 to quickly clamp or release, eliminating the need for complex tools, simplifying the disassembly and assembly process, and shortening equipment downtime.

[0051] During operation, cylinder 6 drives clamping block 5 to move towards hot stamping plate 2, pressing it with a force perpendicular to the pulling direction to achieve fixation. When changing, cylinder 6 reverses direction, driving clamping block 5 away from hot stamping plate 2 to release the clamping force. The clamping force is perpendicular to the pulling direction, effectively counteracting the impact force during operation and ensuring stable positioning of hot stamping plate 2. Simultaneously, the movement path of clamping block 5 when released does not interfere with the pulling path, ensuring smooth operation.

[0052] When replacing the hot stamping plate 2, first raise the stamping mechanism to its highest point, then pull the hot stamping plate 2 horizontally using the pull tool, causing it to detach from the mounting plate 1 along the guide assembly 4. Next, transfer the pulled-out hot stamping plate 2 to the symmetrically arranged support arm assembly 3. The support arm assembly 3 supports the hot stamping plate 2, completely detaching it from the mounting plate 1. The rotating slide 32's flipping function easily adjusts the posture of the hot stamping plate 2, facilitating inspection, cleaning, and other maintenance work by operators outside the equipment, avoiding the risks of operating in confined spaces. The rotating slide 32 of the support arm assembly 3 can rotate around an axis perpendicular to the pulling direction, and the slide has a groove 321. The hot stamping plate 2 is placed in the groove 321 and can rotate or flip with the rotating slide 32.

[0053] In another embodiment of this application, please refer to Figure 6 The support arm assembly 3 is provided with a support part, which extends along the sliding direction of the hot stamping plate 2.

[0054] Specifically, the support portion on the support arm assembly 3 extends along the sliding direction of the hot stamping plate 2. The support portion includes at least two support platforms 31, which are spaced vertically along the direction perpendicular to the withdrawal of the hot stamping plate 2, forming a guide channel. When the hot stamping plate 2 is placed on the support arm assembly 3, the upper and lower support platforms 31 constrain the hot stamping plate 2 from its upper and lower sides, respectively, not only bearing the weight of the hot stamping plate 2 but also restricting its vertical displacement. Even if the hot stamping plate 2 is rotated and flipped on the support arm assembly 3, the upper and lower support platforms 31 can still constrain its horizontal displacement. The spaced support platforms 31 form a closed guide channel, preventing the hot stamping plate 2 from warping vertically or shifting horizontally due to gravity or external forces during support, ensuring stability. During the flipping operation, the support platforms 31 restrict the displacement of the hot stamping plate 2, preventing accidental slippage and reducing the safety risk to operators caused by the hot stamping plate 2 falling, while also ensuring that the hot stamping plate 2 is not damaged by collision during maintenance.

[0055] In another embodiment of this application, please refer to Figure 6 The support arm assembly 3 includes a fixed section 33 and a movable section 34. The fixed section 33 is fixed on the frame near the mounting plate 1. One end of the movable section 34 is rotatably connected to the fixed section 33. A limit seat 331 is provided on the fixed section 33.

[0056] Specifically, the support arm assembly 3 is divided into a fixed section 33 and a movable section 34. The fixed section 33 is fixed to the frame near the mounting plate 1. One end of the movable section 34 is hinged to the fixed section 33 via a pivot perpendicular to the pulling direction, allowing it to rotate around the pivot. The fixed section 33 has a limit seat 331, which is protruding. When the hot stamping plate 2 needs to be replaced, the movable section 34 is rotated away from the frame around the pivot until it abuts against the limit seat 331. The limit seat 331 prevents the movable section 34 from rotating further, keeping it in a horizontal supporting posture. After replacement, the movable section 34 is rotated towards the mounting plate 1 around the pivot, folding it close to the frame. The foldable design of the movable section 34 allows it to be folded up close to the frame when not in use, without occupying extra operating space. This is especially suitable for compact workshop layouts, improving the tidiness of the equipment area. The limiting seat 331 ensures that the movable section 34 is accurately kept horizontal when it is unfolded, and avoids the hot stamping plate 2 from being unstable due to the tilt of the movable section 34. At the same time, the fixed section 33 is fixed to the frame, which enhances the overall support stability of the support arm assembly 3.

[0057] In another embodiment of this application, please refer to Figure 6 The groove 321 is provided with a movable stop 322, which is connected to the side wall of the rotary slide 32 through an elastic element.

[0058] Specifically, when the hot stamping plate 2 is pushed into the groove 321, the end of the hot stamping plate 2 presses against the stop block 322 or the elastic element is manually compressed, causing the stop block 322 to retract towards the side wall of the groove 321, allowing the hot stamping plate 2 to enter the space. After the hot stamping plate 2 is fully embedded in the groove 321, the elastic element returns to its original shape, pushing the stop block 322 back to its original position, blocking the hot stamping plate 2 on the side away from the opening of the groove 321. In addition, when the hot stamping plate 2 is pulled to the end of the support arm assembly 3, the end is embedded in the groove 321. The operator can rotate the rotary slide 32 to rotate the hot stamping plate 2 around the horizontal axis, and the rotary slide 32 converts sliding friction into rotational friction.

[0059] The stop block 322 resets under the action of the elastic element, effectively preventing the hot stamping plate 2 from accidentally sliding out of the groove 321, avoiding damage to the hot stamping plate 2 during disassembly or flipping, and improving operational safety. The rotating slide 32 converts sliding friction into rotational friction, reducing flipping resistance. Even with a heavy hot stamping plate 2, it can be easily operated by a single person. At the same time, the rotating axis is perpendicular to the pulling direction, ensuring that the flipping and pulling actions do not interfere with each other, and the operation logic is clear.

[0060] In another embodiment of this application, please refer to Figure 6 The end of the stop block 322 facing the opening of the groove 321 has a rounded chamfer.

[0061] Specifically, when the hot stamping plate 2 is pushed into the groove 321, the end of the hot stamping plate 2 first contacts the chamfered surface of the stop block 322. As the pushing force is applied, the chamfered surface guides the end of the hot stamping plate 2 to smoothly press against the stop block 322, allowing the stop block 322 to retract smoothly under the action of the elastic element, without the need for additional manual adjustment of the stop block 322's position. The rounded chamfer avoids sharp edges at the opening end of the stop block 322, reducing jamming when the hot stamping plate 2 is pushed in, eliminating the need for manual assistance in compressing the elastic element, simplifying the placement of the hot stamping plate 2, and improving replacement efficiency. The chamfered surface guides the contact, preventing direct rigid collision between the end of the hot stamping plate 2 and the stop block 322, reducing wear on both, and extending the service life of the stop block 322 and the hot stamping plate 2.

[0062] In another embodiment of this application, please refer to Figure 3 , 5 The guide component 4 includes a boss and a groove that mates with the boss.

[0063] Specifically, the boss and the groove are respectively located on the mounting plate 1 and the hot stamping plate 2, or vice versa, forming a sliding fit structure. When the hot stamping plate 2 is pulled out, the boss slides along the length of the groove, limiting the hot stamping plate 2 to move only along the extension direction of the groove, thus constraining the pulling trajectory. The fit structure between the boss and the groove prevents the hot stamping plate 2 from shifting or tilting laterally during pulling out, ensuring accurate movement trajectory, reducing component jamming or collisions caused by shifting, and improving the smoothness of assembly and disassembly.

[0064] In another embodiment of this application, please refer to Figure 3, 5 The groove body and the boss slide together, and the boss is a dovetail-shaped boss 41, and the groove body is a dovetail groove 42 that matches the dovetail-shaped boss 41.

[0065] Specifically, compared to ordinary bosses and grooves, the dovetail-shaped boss 41 and dovetail groove 42 add vertical constraints, which not only limit the horizontal pulling path but also prevent vertical offset during the pulling of the hot stamping plate 2, ensuring accurate movement trajectory and avoiding jamming. The dovetail-shaped boss 41 and dovetail groove 42 have a larger contact surface, resulting in more even force distribution during sliding and reducing local wear. At the same time, the vertical constraints improve the overall stability of the hot stamping plate 2 during operation, indirectly ensuring the accuracy of hot stamping.

[0066] In another embodiment of this application, please refer to Figure 5 An elastic pad 51 is provided on the contact surface between the clamping block 5 and the hot stamping plate 2.

[0067] Specifically, when the clamping block 5 presses the hot stamping plate 2 under the drive of the cylinder 6, the elastic pad 51 on the contact surface deforms. On the one hand, the elastic pad 51 increases the contact area through slight deformation, providing a more uniform and reliable clamping force and preventing excessive local stress from damaging the plate surface. On the other hand, it plays a role in buffering and shock absorption, absorbing the vibration during equipment stamping, and improving the stability of clamping and the life of components.

[0068] In another embodiment of this application, please refer to Figure 2 The piston rod of cylinder 6 moves in a direction perpendicular to the extraction direction of hot stamping plate 2.

[0069] Specifically, the piston rod is connected to the clamping block 5. The extension and retraction of the piston rod provides the clamping block 5 with the driving force to press or release the hot stamping plate 2, thereby realizing the quick locking and unlocking of the hot stamping plate 2.

[0070] In another embodiment of this application, please refer to Figure 1 It also includes a limiting mechanism 7, which is located at the end of the guide assembly 4 away from the clamping block 5.

[0071] Specifically, the limiting mechanism 7 ensures that the hot stamping plate 2 reaches the precise predetermined position each time it is installed, eliminating quality and equipment risks caused by improper installation and achieving fast and accurate positioning.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
