Technical Field

[0001] This utility model relates to the field of marking machine technology, specifically to an online synchronous marking and punching machine. Background Technology

[0002] In continuous industrial production scenarios, planar materials (such as films, paper, and fabrics) often need to be marked at specific locations during production to facilitate identification, cutting, or removal of defective areas in subsequent processes.

[0003] In order to improve work efficiency, some existing online drilling equipment can achieve a certain degree of automation. However, due to the failure of its drive and control system to achieve high-precision synchronization with the material running speed, problems such as inaccurate drilling position, blurred markings, or material stretching and deformation often occur, which have certain shortcomings.

[0020] 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.

[0021] Please see Figures 1-9This utility model provides a technical solution: an online synchronous marking and punching machine, including a base 1 and a support frame 2 mounted on the base 1. A punching assembly is provided on the support frame 2, and a driving mechanism for driving the punching assembly to rotate is also provided on the support frame 2. The punching assembly includes a lower cutter roller 3 rotatably connected to the support frame 2 and an upper cutter roller 4 movably mounted on the support frame 2. The product moves between the upper cutter roller 4 and the lower cutter roller 3, and a punching part is provided between the upper cutter roller 4 and the lower cutter roller 3. A pressure mechanism is provided on the base 1 for driving the upper cutter roller 4 to move towards the lower cutter roller 3.

[0022] Specifically, this online synchronous marking and punching machine includes a base 1 and a support frame 2 mounted on the base 1. The support frame 2 is connected to the base 1 by bolts to improve structural stability. A punching assembly is mounted on the support frame 2, and a drive mechanism is also provided to rotate the punching assembly to a predetermined position to meet the punching operation requirements. The punching assembly includes a lower cutter roller 3 rotatably connected to the support frame 2 and an upper cutter roller 4 movably mounted on the support frame 2. The product moves between the upper cutter roller 4 and the lower cutter roller 3. A punching section is provided between the upper cutter roller 4 and the lower cutter roller 3. A pressure mechanism is provided on the base 1 to drive the upper cutter roller 4 towards the lower cutter roller 3. When punching is required, the pressure mechanism drives the upper cutter roller 4 towards the lower cutter roller 3, thus performing the punching operation. Therefore, the coordinated operation of the drive mechanism and the pressure mechanism in this equipment ensures high-precision synchronization between the punching process and the material's running speed, effectively avoiding the inefficiency and positional deviation problems caused by traditional manual marking or offline punching. The design of the punching component allows products to be marked during continuous movement, improving production efficiency and quality stability, while reducing the risk of material stretching and deformation. It is suitable for online processing of planar materials such as films and paper.

[0023] In the embodiments provided by this utility model, the punching part includes a punching knife 41 disposed on the upper knife holder roller 4, and a punching groove 31 adapted to the punching knife 41 is provided on the lower knife holder roller 3. Specifically, the matching design of the punching knife 41 and the punching groove 31 ensures the accuracy and consistency of punching, and avoids unclear markings or incorrect positions.

[0024] In the embodiments provided by this utility model, the upper cutter roller 4 is mounted on the support frame 2 via a first linkage rod 9, i.e., the first linkage rod 9 is movably connected to the support frame 2. The lower cutter roller 3 is rotatably connected to the support frame 2 via a second linkage rod 10. The driving mechanism includes a servo motor 5, which drives the first linkage rod 9 and the second linkage rod 10 to rotate synchronously via a transmission component. The servo motor 5 provides precise speed and position control, enabling the upper cutter roller 4 and the lower cutter roller 3 to move to predetermined positions, improving the accuracy of drilling.

[0025] In the embodiments provided by this utility model, the pressure applying mechanism includes a swing arm 12, which is rotatably connected to the support frame 2 via a positioning shaft 8, and a first linkage rod 9 is rotatably connected to the swing arm 12. A power unit is also provided on the base 1 to drive the swing arm 12 to rotate. During the stroke of the power unit driving the swing arm 12 to rotate on the support frame 2, the first linkage rod 9 moves on the support frame 2 via a guide. The combination of the swing arm 12 and the guide provides a stable pressure trajectory, ensuring that the upper cutter roller 4 applies uniform pressure during punching. When the first linkage rod 9 moves within the guide and cooperates with the lower cutter roller 3, the punching and marking operation of the product can be achieved with excellent results.

[0026] In the embodiment provided by this utility model, the power unit includes a cylinder 14 mounted on the base 1, and a connecting rod 13 is fixedly connected to the swing arm 12. A pressure block is hinged to the end of the connecting rod 13 away from the swing arm 12, and the output end of the cylinder 14 is connected to the pressure block. Specifically, when the cylinder 14 extends or retracts, it pushes the connecting rod 13 through the pressure block, causing the swing arm 12 to rotate around the positioning shaft 8, thereby driving the upper cutter roller 4 to move and providing power for the drilling operation.

[0027] In the embodiments provided by this utility model, the guide portion includes a motion groove 15 formed on the support frame 2, and a first bearing 91 is installed on the first linkage rod 9. When the swing arm 12 rotates on the support frame 2, the first linkage rod 9 drives the first bearing 91 to move within the motion groove 15. Specifically, the cooperation between the motion groove 15 and the bearing ensures the linear movement and precise positioning of the upper cutter roller 4, avoiding lateral offset or jamming. At the same time, it further improves the accuracy of product drilling from the side.

[0028] In the embodiments provided by this utility model, the transmission component includes a transmission rod 6 rotatably connected to the support frame 2. The servo motor 5 is connected to the transmission rod 6 via a coupling 7. The transmission rod 6 is connected to the positioning shaft 8, the first linkage rod 9, and the second linkage rod 10 via a linkage gear set 11. The linkage gear set 11 includes a first gear 111 mounted on the transmission rod 6, a second gear 112 mounted on the positioning shaft 8, a third gear 113 mounted on the first linkage rod 9, and a fourth gear 114 mounted on the second linkage rod 10. Specifically, refer to... Figure 5 The meshing sequence of the linkage gear set 11 is as follows: the fourth gear 114 meshes with the second gear 112, the second gear 112 meshes with the first gear 111, the first gear 111 meshes with the third gear 113, and the third gear 113 disengages from the fourth gear 114. During this process, the transmission rod 6 transmits power to the positioning shaft 8, the first linkage rod 9, and the second linkage rod 10 through the linkage gear set 11, achieving synchronous transmission of each component.

[0029] In the embodiments provided by this utility model, the servo motor 5 is mounted on the base 1 via an extension bracket, and the servo motor 5 is fixed on the base 1 via the extension bracket. The extension bracket provides additional support points to ensure that the motor is installed securely.

[0030] In the embodiments provided by this utility model, a control mechanism is also provided on the base 1, and the control mechanism is signal-connected to the drive mechanism and the pressure mechanism. Specifically, the control mechanism includes sensor components, encoder components, etc. The cooperation between the servo motor 5, the encoder components, and various sensor components detects the material running speed in real time, and after controlling the rotation speed of the upper cutter roller 4 and the lower cutter roller 3 to be consistent with the material speed, the pressure mechanism immediately drives the upper cutter roller 4 and the lower cutter roller 3 to cooperate in punching the product. At this time, there is no relative movement between the cutter and the material, avoiding pulling or misalignment.

[0031] Working principle: After the equipment is started, the product to be processed (such as flat materials like film and paper) moves continuously between the upper cutter roller 4 and the lower cutter roller 3. The servo motor 5 in the drive mechanism drives the transmission rod 6 to rotate through the coupling 7. The transmission rod 6 transmits power synchronously to the positioning shaft 8, the first linkage rod 9, and the second linkage rod 10 through the linkage gear set 11, so that the upper cutter roller 4 and the lower cutter roller 3 rotate synchronously at a speed precisely matched with the product running speed.

[0032] When the control mechanism (such as an encoder or sensor) detects that the product has moved to the preset punching position, it immediately sends a signal to the pressure mechanism. At this time, the cylinder 14 in the pressure mechanism is activated, pushing the pressure block and the connecting rod 13, causing the swing arm 12 to rotate around the positioning shaft 8. The rotation of the swing arm 12 drives the first linkage rod 9 to move towards the lower cutter roller 3 through the guide part (i.e., the motion groove 15 on the support frame 2 and the first bearing 91), forcing the upper cutter roller 4 to descend. At this time, the punching knife 41 on the upper cutter roller 4 precisely engages with the punching groove 31 on the lower cutter roller 3, and punches and marks the product passing between them.

[0033] After the punching action is completed, cylinder 14 retracts, swing arm 12 returns to its original position, and upper cutter roller 4 moves away from lower cutter roller 3 under the guidance of the guide, allowing the product to continue moving forward. Throughout the process, the coordinated operation of the drive mechanism and the pressure mechanism ensures high-precision synchronization between the punching action and the product's running speed, avoiding problems such as punching position deviation, material stretching and deformation, or blurred markings, thus achieving efficient and accurate online synchronous marking and punching.

[0034] It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source, and this application is equipped with a control system for controlling the operation of the entire equipment.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
