[0001] This utility model relates to the technical field of card embossing devices, and in particular to a quick mold changing device for embossing the surface of paper cards. Background Technology

[0002] In the production of paper cards, embossing is often required to enhance their aesthetics and uniqueness. Embossing devices can create various intricate textures on the card surface using specific embossing modules, and are widely used in the production of greeting cards, invitations, business cards, and other types of paper cards.

[0003] Currently, traditional paper card embossing devices suffer from numerous problems when replacing embossing modules. The bolted connections they employ require workers to use external tools like wrenches to tighten the bolts during module replacement. This process is not only laborious but also time-consuming due to the large number of bolts, severely impacting production efficiency. Furthermore, frequent use of tools for bolt handling can easily lead to stripped threads and other damage, increasing equipment maintenance costs. In addition, the complex bolt connections make it difficult for workers to quickly replace embossing modules to meet diverse embossing requirements, hindering timely responses to market demands for different embossing styles and significantly limiting the device's practicality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a quick mold changing device for embossing the surface of paper cards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick mold changing device for embossing the surface of paper cards, comprising: an embossing device body, a crossbar fixedly connected to the upper outer wall of the embossing device body, a connecting mechanism movably connected to the lower end of the crossbar, a snap-fit ​​mechanism fixedly connected to the connecting mechanism, an embossing module movably connected to the lower end of the snap-fit ​​mechanism, and connecting rods fixedly connected to the upper outer walls on both sides of the embossing module;

[0006] The snap-fit ​​mechanism includes a cylinder fixedly connected to a connecting mechanism. A movable block is fixedly connected to the lower end of the cylinder. An observation groove is provided on the side wall of the movable block. A groove is provided at the bottom end of the inner wall of the movable block. A fixing member is movably connected to the outer wall of the lower end of the movable block. A connecting member is fixedly connected to one side of the inner wall of the fixing member. A spring is fixedly connected to the upper end of the connecting member.

[0007] In a preferred embodiment, the upper outer wall of the embossing device body is provided with an embossing area, a controller is fixedly connected to one side of the upper outer wall of the crossbar, the connecting mechanism includes a connecting block, a drive wheel is fixedly connected to the upper end of the connecting block, an electric telescopic rod is fixedly connected to the lower end of the connecting block, a fixing block is fixedly connected to the lower end of the electric telescopic rod, and a support block is fixedly connected to one side of the upper outer wall of the fixing block.

[0008] In a preferred embodiment, the drive wheel at the upper end of the connecting block is movably connected to the lower end of the inner wall of the crossbar.

[0009] In a preferred embodiment, the cylinder is located on the upper outer wall of the support block, and the movable block at the lower end extends to one side of the upper end of the fixed block.

[0010] In a preferred embodiment, the fastener is fixedly connected to one side of the inner wall of the fixing block.

[0011] In a preferred embodiment, the lower outer wall of the movable block is connected to the upper inner wall of the fixing member.

[0012] In a preferred embodiment, the groove at the lower end of the inner wall of the movable block is connected to a spring piece on one side of the inner wall of the fixing member.

[0013] In one preferred embodiment, the connecting rod at the upper end of the embossing module is sequentially connected to the fixing component, the connecting component, the spring piece, and the movable block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model, through its innovative snap-fit ​​mechanism, eliminates the traditional bolt connection method, significantly improving the efficiency of embossing module replacement. Traditional bolt connections require external tools, and the disassembly process is laborious and time-consuming. The snap-fit ​​mechanism, however, utilizes a cylinder to drive the movable block longitudinally, with the groove at the lower end of the movable block cooperating with the spring piece inside the fixing component. During installation, simply align the connecting rod of the embossing module with the slot in the fixing component, insert it through the connecting component and the spring piece to one side of the inner wall of the movable block, confirm the connection through the observation slot, then activate the cylinder. The movable block moves downward, causing the groove to gather the spring piece, wrapping and clamping the connecting rod, completing the installation. Disassembly is performed by reversing the operation, enabling quick and convenient replacement of different embossing modules, greatly increasing the practicality of the device and meeting diverse embossing needs.

[0016] 2. In use, the embossing area on the upper outer wall of the embossing device body is equipped with a sensor that can accurately detect whether the paper card is completely placed on the upper end of the embossing area. Subsequent embossing operations will only proceed when the card is accurately positioned, fundamentally preventing embossing misalignment, effectively ensuring embossing quality, reducing scrap rate, and improving production efficiency and product consistency.

[0017] 3. In use, the electric drive system on the inner wall of the crossbar works closely with the connecting mechanism. The connecting block in the connecting mechanism is connected to the inner wall of the crossbar via a drive wheel. The electric drive rotates the drive wheel, easily moving the connecting block and allowing the entire device to flexibly adjust its position horizontally, facilitating embossing of paper cards at different locations. Simultaneously, the electric telescopic rod at the lower end of the connecting block can extend and retract, moving the fixed block longitudinally. This, in turn, moves multiple locking mechanisms and the embossing module on the fixed block up and down, achieving precise embossing of paper cards in the embossing area. This flexible movement and operation method makes the embossing process more efficient and precise, adapting to embossing tasks with different sizes and positional requirements.

[0032] Example 1

[0033] like Figure 1-5 As shown, this utility model provides a technical solution: a quick mold changing device for embossing the surface of paper cards, comprising: an embossing device body 1, a crossbar 3 fixedly connected to the upper outer wall of the embossing device body 1, a connecting mechanism 5 movably connected to the lower end of the crossbar 3, a snap-fit ​​mechanism 6 fixedly connected to the connecting mechanism 5, an embossing module 7 movably connected to the lower end of the snap-fit ​​mechanism 6, and connecting rods 8 fixedly connected to the upper outer walls on both sides of the embossing module 7.

[0034] The snap-fit ​​mechanism 6 includes a cylinder 61 fixedly connected to the connecting mechanism 5. A movable block 62 is fixedly connected to the lower end of the cylinder 61. An observation groove 63 is provided on the side wall of the movable block 62. A groove 64 is provided at the bottom end of the inner wall of the movable block 62. A fixing member 65 is movably connected to the lower outer wall of the movable block 62. The lower outer wall of the movable block 62 is correspondingly connected to the upper inner wall of the fixing member 65. A connecting member 66 is fixedly connected to one side of the inner wall of the fixing member 65. A spring piece 67 is fixedly connected to the upper end of the connecting member 66. A connecting rod 8 provided at the upper end of the embossing module 7 is sequentially connected to the fixing member 65, the connecting member 66, the spring piece 67 and the movable block 62. The groove 64 provided at the lower end of the inner wall of the movable block 62 is correspondingly connected to the spring piece 67 provided on one side of the inner wall of the fixing member 65.

[0035] In this embodiment, an embossing device body 1 is designed, with a crossbar 3 fixedly connected to the upper end of the body 1. An electric drive is provided on the inner wall of the crossbar 3, and a connecting mechanism 5 is provided on one side of the inner wall of the crossbar 3. Multiple snap-fit ​​mechanisms 6 are provided on both sides of the lower end of the connecting mechanism 5. The lower end of the snap-fit ​​mechanism 6 is connected to the embossing module 7 and the connecting rod 8. Then, the device can be moved to the appropriate position for embossing operation by electric drive. In use, the embossing pattern needs to be changed to increase the practicality of the device. However, existing devices mostly use bolt connections. Disassembly requires additional tools and considerable force. To address this, a locking mechanism 6 is provided. The locking mechanism 6 includes a cylinder 61, with a movable block 62 fixedly connected to its lower end. Therefore, the cylinder 61 can drive the movable block 62 to move longitudinally. A groove 64 is formed on the lower end of one side of the inner wall of the movable block 62, and an observation slot 63 is formed on its upper end. A fixing member 65 is provided on the lower outer wall of the movable block 62, and a connecting member 66 is fixedly connected to one side of the inner wall of the fixing member 65. Four spring pieces 67 are arranged in a circular array on the upper end of the connecting member 66. The piece 67 typically shifts outwards, and the spring piece 67 has a certain degree of elasticity. The embossing module 7 is located at the lower end of the fixing member 65. When the embossing module 7 needs to be installed, the connecting rod 8 at the upper end of the embossing module 7 can be aligned with the slot in the middle of the fixing member 65. At this time, the connecting rod 8 will pass through the connecting member 66 and the spring piece 67, thus extending to one side of the inner wall of the movable block 62. At this time, it can be observed through the observation slot 63 whether the connecting rod 8 is connected to the movable block 62. When connected, the cylinder 61 can be activated, and the cylinder 61 will drive the movable block 62 to move downwards. When the movable block 62 is activated, it will connect with the inner wall of the upper end of the fixed part 65. At this time, the groove 64 opened at the bottom end of the inner wall of the movable block 62 will act on the upper end of the spring piece 67. At this time, the shape of the spring piece 67 corresponds to that of the groove 64. The spring piece 67 will be gathered together by the groove 64, thereby wrapping the connecting rod 8. Then the spring piece 67 will clamp the connecting rod 8, thus completing the installation operation of the embossing module 7. Conversely, it can be disassembled. This method realizes the quick disassembly and installation of the embossing module 7, thereby replacing different embossing patterns.

[0036] Example 2

[0037] like Figure 1-4As shown, the upper outer wall of the embossing device body 1 is provided with an embossing area 2, and a controller 4 is fixedly connected to one side of the upper outer wall of the crossbar 3. The connecting mechanism 5 includes a connecting block 51, a drive wheel 52 is fixedly connected to the upper end of the connecting block 51, the drive wheel 52 at the upper end of the connecting block 51 is movably connected to the lower end of the inner wall of the crossbar 3, an electric telescopic rod 53 is fixedly connected to the lower end of the connecting block 51, a fixing block 54 is fixedly connected to the lower end of the electric telescopic rod 53, a fixing member 65 is fixedly connected to one side of the inner wall of the fixing block 54, a support block 55 is fixedly connected to one side of the upper outer wall of the fixing block 54, a cylinder 61 is provided on the upper outer wall of the support block 55, and the movable block 62 at the lower end extends to one side of the upper end of the fixing block 54.

[0038] In this embodiment, an embossing area 2 is provided on the upper outer wall of the embossing device body 1. The embossing area 2 has a sensor, which ensures that the paper card to be embossed is completely placed on the upper end of the embossing area 2, thereby performing subsequent embossing operations and avoiding embossing misalignment. Meanwhile, the connecting mechanism 5 is moved by an electric drive at the lower end of the inner wall of the crossbar 3. The connecting mechanism 5 includes a connecting block 51, the upper end of which is connected to the inner wall of the crossbar 3 via a drive wheel 52. Thus, the drive wheel 52 can drive the connecting block 51 to move, thereby driving the device... The device is moved, and a fixed block 54 is fixedly connected to the lower end of the connecting block 51 via an electric telescopic rod 53. A support block 55 is fixedly connected to the upper outer wall of the fixed block 54. The upper end of the support block 55 is fixedly connected to the lower end of the cylinder 61. The inner wall of the fixed block 54 is fixedly connected to the outer wall of the fixing member 65. The electric telescopic rod 53 has a telescopic function, which can drive the fixed block 54 to move longitudinally, thereby driving the multiple snap-fit ​​mechanisms 6 provided on the fixed block 54 to move longitudinally, and then driving the embossing module 7 to perform embossing operation on the paper card placed on the embossing area 2.

[0039] like Figure 1-5As shown, the embossing device mainly consists of an embossing device body 1, a crossbar 3, a connecting mechanism 5, a snap-fit ​​mechanism 6, and an embossing module 7. The crossbar 3 is fixed to the upper end of the embossing device body 1. An electric drive system is installed on the inner wall of the crossbar 3 to drive the movement of various parts of the device. The connecting mechanism 5 is connected to the crossbar 3 via one side of its inner wall. Multiple snap-fit ​​mechanisms 6 are arranged on both sides of its lower end. The embossing module 7 and connecting rod 8 are connected below the snap-fit ​​mechanisms 6. The snap-fit ​​mechanism 6 is a key component for enabling quick disassembly and installation of the embossing module 7. The snap-fit ​​mechanism 6 includes components such as a cylinder 61, a movable block 62, a fixing part 65, a connecting part 66, and a spring piece 67. When the embossing module 7 needs to be installed, the connecting rod 8 at the upper end of the embossing module 7 is aligned with the slot in the middle of the fixing part 65, allowing the connecting rod 8 to pass through the connecting part 66 and the spring piece 67, extending to one side of the inner wall of the movable block 62. The connection between the connecting rod 8 and the movable block 62 can be confirmed through the observation slot 63 at the upper end of the movable block 62. After confirming the connection, cylinder 61 is activated, causing the movable block 62 to move downwards and align with the inner wall of the upper end of the fixing component 65. At this time, the groove 64 at the bottom of the inner wall of the movable block 62 acts on the upper end of the spring piece 67. Because the spring piece 67 is elastic and generally offsets outwards, the groove 64 gathers the spring piece 67 together, thus encasing the connecting rod 8 and firmly clamping the embossing module 7. For disassembly, cylinder 61 is operated in reverse to move the movable block 62 upwards, restoring the spring piece 67 to its original position, allowing the embossing module 7 to be easily removed. This design greatly improves the efficiency of replacing the embossing module 7 and facilitates the use of different embossing styles. The upper outer wall of the embossing device body 1 has an embossing area 2, which is equipped with a sensor to accurately detect whether the paper card to be embossed is completely placed on the embossing area 2. Subsequent embossing operations are only performed when the card is correctly positioned, effectively avoiding embossing misalignment. The electric drive system at the lower end of the inner wall of the crossbar 3 drives the drive wheel 52 in the connecting mechanism 5, which in turn moves the connecting block 51 within the crossbar 3, thereby adjusting the horizontal position of the entire device. The electric telescopic rod 53 at the lower end of the connecting block 51 can extend and retract, causing the fixed block 54 to move longitudinally. Multiple snap-fit ​​mechanisms 6 are connected to the fixed block 54, which in turn drives the embossing module 7 to perform embossing operations on the paper cards in the embossing area 2. In summary, this embossing device, through its reasonable structural design and ingenious mechanical linkage, achieves rapid replacement of the embossing module 7 and precise embossing operation, improving work efficiency and embossing quality.
