Description

Technical Field

[0001] This utility model relates to the technical field of printing roller processing equipment, and in particular to a cutter head structure for printing roller processing that facilitates tool replacement. Background Technology

[0002] Printing roller processing is a critical process in the printing industry, and its processing accuracy directly affects printing quality. Currently, printing roller processing equipment adopts a fixed cutter head structure, with the cutters fixed to the cutter head by bolts or pressure plates. As the printing industry develops towards small batches and multiple varieties, the demand for printing roller processing is becoming increasingly diversified, and frequent cutter changes have become the norm. The traditional fixed cutter head structure requires the disassembly of multiple fasteners when changing cutters, which is cumbersome and time-consuming, seriously affecting production efficiency. In addition, manual disassembly can cause a decrease in the positioning accuracy of the cutters, which in turn affects the processing quality.

[0003] A search revealed Chinese Patent Publication No. CN220837942U, which discloses an automated gravure printing roller turning device and its usage method. The device includes a machine body, a clamping mechanism, and a turning mechanism. The clamping mechanism is connected to the machine body and is used to clamp the printing roller blank and drive it to rotate. The turning mechanism includes a movable seat, a cutter head, and a drive component. The movable seat is slidably connected to the machine body, the cutter head is rotatably connected to the movable seat, and the drive component is connected to the movable seat and the cutter head to drive its rotation. The cutter head is equipped with multiple different types of cutters. The movable seat slides to drive the cutters on the cutter head to turn the printing roller blank. This application has the effect of improving the efficiency of printing roller turning. However, when it is necessary to replace the cutters, the device requires first removing the support tray from the fixed plate, and then disassembling and replacing the individual cutters on the support tray, which is cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutter head structure for printing roller processing that facilitates tool replacement, aiming to improve the problem of cumbersome operation in the prior art, which requires first removing the support plate from the fixed plate and then disassembling and replacing the individual tools on the support plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutter head structure for easy tool replacement in printing roller processing, comprising a frame, a support rod fixedly connected to the left side of the inner wall of the frame, a quick-release mechanism provided on the outside of the support rod, a turntable rotatably connected to the outer wall of the support rod, and a shifting mechanism provided inside the turntable;

[0006] The quick-release mechanism includes a multi-position cutter disc. The right side of the outer wall of the multi-position cutter disc is fixedly connected to the left side of the outer wall of the turntable. The outer wall of the multi-position cutter disc has multiple mounting slots. The inner wall of each of the multiple mounting slots is slidably connected to a mounting seat. The outer walls of each of the multiple mounting seats are fixedly connected to a handle on the side away from each other. The outer walls of each of the multiple handles are fixedly connected to a blade head on the side away from each other. The interior of each of the multiple mounting slots is provided with a positioning component. The exterior of the multi-position cutter disc is provided with multiple locking wheel assemblies, multiple locking components, and multiple anti-detachment components.

[0007] Through the above technical solution: the frame and support rod form a stable support frame, providing an installation base for the quick-release mechanism and turntable. In the quick-release mechanism, multiple tool discs are connected to the turntable and can switch tool positions as the turntable rotates. The design of multiple mounting slots and mounting seats allows multiple tool units to be integrated and installed on the multiple tool discs. The positioning component ensures the initial position accuracy of the tool during installation. The locking wheel component, locking component, and anti-loosening component work together to achieve quick locking and anti-loosening of the tool.

[0008] As a further description of the above technical solution:

[0009] The shifting mechanism includes a fixing block, the outer wall of which is fixedly connected to the outer wall of the support rod. The inner wall of the turntable has a rotating groove. Multiple return springs are fixedly connected to the left side of the inner wall of the turntable. Multiple locking blocks are slidably connected to the inner wall of the turntable. Pressure rods are fixedly connected to the right side of the outer wall of each locking block. Two limiting blocks are fixedly connected to the outer wall of the support rod.

[0010] Through the above technical solution: the cooperation between the fixed block and the rotating groove provides a stable rotation axis for the turntable; the reset spring, the locking block and the pressure rod form a convenient unlocking and locking structure; the operator only needs to press the pressure rod to easily switch the rotation and locking states of the turntable; the limit block restricts the rotation range of the turntable to prevent it from sliding radially and ensures the accuracy of tool changing.

[0011] As a further description of the above technical solution:

[0012] The positioning component includes two spring steel columns, the outer walls of which are slidably connected to the inner wall of the mounting groove, and the outer wall of the mounting base has two positioning grooves.

[0013] Through the above technical solution, the cooperation between the spring steel column and the positioning groove can automatically center the tool during installation. The elastic buffer of the spring steel column can reduce rigid collisions during installation, ensuring that the tool is quickly installed to the preset position, reducing manual calibration time and errors.

[0014] As a further description of the above technical solution:

[0015] The locking wheel assembly includes a rotating shaft, the outer wall of which is fixedly connected to the left side of the outer wall of the multi-position cutter head. An eccentric wheel is rotatably connected to the outer wall of the rotating shaft. A wheel groove is provided on the left side of the outer wall of the mounting base. A wheel handle is fixedly connected to the outer wall of the eccentric wheel.

[0016] Through the above technical solution: when the eccentric wheel rotates around the shaft, the radial pressure generated by the eccentric structure is used to firmly lock the mounting seat in the mounting groove. The wheel handle is easy to operate manually, realizing quick locking and unlocking, and ensuring that the tool remains stable during the processing.

[0017] As a further description of the above technical solution:

[0018] The locking assembly includes multiple inserts, the outer walls of which are fixedly connected to the left side of the outer wall of the multi-position cutter head, and the inner walls of the multiple inserts on the same side are slidably connected to the same insert rod.

[0019] The above technical solution involves the insertion plate and the insertion rod working together to limit the rotation position of the wheel handle, ensuring that the eccentric wheel will not rotate arbitrarily after locking, thus enhancing the reliability of tool locking.

[0020] As a further description of the above technical solution:

[0021] The anti-detachment component includes two paddles, the inner walls of the two paddles are respectively fixedly connected to the outer walls of the two inserts on the same side, and an anti-detachment spring is fixedly connected to the outer walls of the two paddles.

[0022] The above technical solution uses a spring to apply pressure to the insert rod via a lever, preventing the insert rod from unlocking accidentally and ensuring that the tool remains locked even under vibration, thus improving machining safety.

[0023] As a further description of the above technical solution:

[0024] The inner wall of the frame is slidably connected to two roller seats, and the inner walls of the two roller seats are slidably connected to the same roller.

[0025] The above technical solution provides support and positioning for printing roller processing through the cooperation between the roller holder and the roller. The sliding design of the roller holder can adjust the position of the roller to adapt to the processing needs of printing rollers of different specifications.

[0026] As a further description of the above technical solution:

[0027] The inner wall of the rotating groove is rotatably connected to the outer wall of the fixed block, and the right ends of the multiple reset springs are respectively fixedly connected to the left side of the outer wall of the multiple locking blocks.

[0028] The above technical solution ensures smooth rotation of the turntable by rotating the slot and fixing block, and the reset spring provides automatic reset power for the locking block, ensuring that the turntable can be quickly locked after being repositioned.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the clamping force provided by the radial pressure generated by the eccentric wheel can fix the mounting seat in the mounting groove, ensuring the stability of the tool in the processing environment of high-speed rotation and severe vibration. Through the cooperation of the insert and the insert rod of the locking component, the wheel handle can be locked after it is rotated into place, ensuring the locking state of the eccentric wheel. At the same time, the tool can be installed and removed by rotating the eccentric wheel without complicated tools, shortening the tool change time and improving the production efficiency of printing roller processing.

[0031] 2. In this utility model, the linkage design of the pressure rod and the locking block allows the operator to release the lock of the turntable simply by pressing the pressure rod to the left. The stable locking structure formed by the fixed block and the two adjacent locking blocks allows the turntable and the multi-position cutter head to be locked after the cutter is switched. At the same time, rotating the turntable can drive the external cutter to rotate synchronously, realizing the rapid switching of multiple cutters and meeting the needs of different processes in the printing roller processing.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0040] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model provides a tool disc structure for easy tool replacement in printing roller processing, including a frame 1, a support rod 2 fixedly connected to the left side of the inner wall of the frame 1, a quick-release mechanism 3 provided on the outside of the support rod 2 for quick installation and removal of the tool, a turntable 4 rotatably connected to the outer wall of the support rod 2, and a switching mechanism 5 provided inside the turntable 4 for switching the tool.

[0041] The quick-release mechanism 3 includes a multi-position cutter head 301. The right side of the outer wall of the multi-position cutter head 301 is fixedly connected to the left side of the outer wall of the turntable 4, realizing the fixed connection between the quick-release mechanism 3 and the turntable 4. The outer wall of the multi-position cutter head 301 has multiple mounting grooves 302 for accommodating and mounting mounting seats 303. The inner walls of the multiple mounting grooves 302 are slidably connected to the mounting seats 303, allowing the mounting seats 303 to slide within the mounting grooves 302, facilitating the installation and removal of tools. Tool holders 304 are fixedly connected to the outer walls of the multiple mounting seats 303 on opposite sides, for connecting the tool head 305 and transmitting cutting force. The outer walls of the multiple tool holders 304 are... Each side of the wall away from the cutting head 305 is fixedly connected to realize the processing operation of the printing roller. The interior of each of the multiple mounting slots 302 is provided with a positioning component 306 to ensure that the mounting base 303 is accurately positioned during installation. The exterior of the multi-position cutting head 301 is provided with multiple locking wheel components 307 to lock the mounting base 303 and prevent it from loosening. The exterior of the multi-position cutting head 301 is provided with multiple locking components 308 to limit and lock the wheel handle 3074 in conjunction with the locking wheel components 307. The exterior of the multi-position cutting head 301 is provided with multiple anti-detachment components 309 to prevent the locking wheel components 307 from being accidentally unlocked and to ensure the stability of the cutting tool installation.

[0042] The locking wheel assembly 307 includes a rotating shaft 3071. The outer wall of the rotating shaft 3071 is fixedly connected to the left side of the outer wall of the multi-position cutter head 301, providing a rotating shaft for the eccentric wheel 3072. The eccentric wheel 3072 is rotatably connected to the outer wall of the rotating shaft 3071. The rotation generates radial pressure to fix the mounting seat 303. A wheel groove 3073 is opened on the left side of the outer wall of the mounting seat 303, which cooperates with the eccentric wheel 3072 to fix the mounting seat 303. A wheel handle 3074 is fixedly connected to the outer wall of the eccentric wheel 3072 to facilitate the operator to rotate the eccentric wheel 3072. The locking assembly 308 includes multiple inserts 3081 and multiple inserts 3082. The outer wall of 1 is fixedly connected to the left side of the outer wall of the multi-position cutter head 301, providing a sliding track for the insertion rod 3082. The inner walls of multiple insertion plates 3081 on the same side are slidably connected to the same insertion rod 3082, which is used to limit the rotation position of the wheel handle 3074. The anti-disengagement component 309 includes two paddles 3091. The inner walls of the two paddles 3091 are respectively fixedly connected to the outer walls of the two insertion rods 3082 on the same side, which makes it easy for the operator to control the movement of the insertion rod 3082. The outer walls of the two paddles 3091 are fixedly connected to anti-disengagement springs 3092, so that the insertion rod 3082 automatically resets after the unlocking operation, ensuring the reliability of the lock position.

[0043] Specifically, during installation, after inserting the mounting base 303 into the mounting slot 302, move the levers 3091 on both sides of the eccentric wheel 3072 upwards. The insert rod 3082 moves upwards, releasing the restriction on the wheel handle 3074. Rotate the wheel handle 3074 between the inserts 3081 on the left side of the eccentric wheel 3072. Lower the levers 3091, and the insert rod 3082 on the right side will lock the wheel handle 3074 into the current position. During this process, the eccentric wheel 3072 rotates, and its outer wall is inserted into the wheel groove 3073, fixing the mounting base 303 in the current position. Disassembly is performed by reversing the operation.

[0044] See attached document Figure 1 Appendix Figure 2 and attached Figure 5 The switching mechanism 5 includes a fixed block 501, the outer wall of which is fixedly connected to the outer wall of the support rod 2, providing a stable rotation center for the turntable 4. A rotating groove 502 is formed on the inner wall of the turntable 4, and the inner wall of the groove 502 is rotatably connected to the outer wall of the fixed block 501, allowing the turntable 4 to rotate flexibly around the fixed block 501. Multiple return springs 503 are fixedly connected to the left side of the inner wall of the turntable 4, providing a return elastic force for the locking blocks 504. Multiple locking blocks 504 are slidably connected to the inner wall of the turntable 4. The positioning and locking of the turntable 4 after rotation is achieved in cooperation with the fixed block 501. The right ends of multiple return springs 503 are respectively fixedly connected to the left side of the outer wall of multiple locking blocks 504 to ensure that the locking blocks 504 can automatically reset after being unlocked. The right side of the outer wall of multiple locking blocks 504 is fixedly connected to a pressure rod 505, which makes it easy for the operator to manually control the movement of the locking blocks 504 to realize the locking and unlocking operation. The outer wall of the support rod 2 is fixedly connected to two limit blocks 506 to limit the rotation angle range of the turntable 4 and prevent it from rotating excessively.

[0045] Specifically, when it is necessary to switch the tools on the multi-position tool turret 301 for machining, the top pressure rod 505 is pressed to the left. At this time, the adjacent locking block 504 slides to the left and no longer contacts the outer wall of the fixed block 501. Then, the turntable 4 is rotated. When the turntable 4 rotates, it drives the multi-position tool turret 301 connected to it and the tools outside it to rotate synchronously. When the fixed block 501 is in contact with another locking block 504, the pressure rod 505 is released. The locking block 504 connected to it is reset under the action of the return spring 503. At this time, the fixed block 501 and the two adjacent locking blocks 504 are engaged, fixing the turntable 4 and the multi-position tool turret 301 connected to it in the current position, thus completing one tool change. During the rotation, the limit block 506 restricts the axial movement of the turntable 4 to prevent the position of the tool head 305 from shifting.

[0046] See attached document Figure 1 Appendix Figure 2 and attached Figure 3The positioning component 306 includes two spring steel columns 3061. The outer walls of the two spring steel columns 3061 are slidably connected to the inner wall of the mounting groove 302. The elastic deformation of the spring steel columns 3061 achieves the pre-positioning and buffering effect on the mounting seat 303. The outer wall of the mounting seat 303 has two positioning grooves 3062, which cooperate with the spring steel columns 3061 to achieve the positioning of the mounting seat 303 in the mounting groove 302. The inner wall of the frame 1 is slidably connected to two roller seats 6. The inner walls of the two roller seats 6 are slidably connected to the same roller 7. The roller seats 6 fix the roller 7 in the frame 1.

[0047] Specifically, in the positioning component 306, two spring steel columns 3061 are slidably connected to the inner wall of the mounting groove 302. Relying on elastic deformation, they pre-position the mounting base 303 and play a buffering role during installation to avoid rigid collisions. The positioning groove 3062 on the outer wall of the mounting base 303 cooperates with the spring steel columns 3061 to ensure that the mounting base 303 is stably installed in the mounting groove 302. The roller seat 6, which is slidably connected to the inner wall of the frame 1, is used to fix and support the roller 7, providing a stable support foundation for the printing roller processing.

[0048] Working principle: When installing the tool, first slide the mounting base 303 into the mounting groove 302. At this time, the positioning component 306 plays a role in ensuring the initial position of the tool is accurate. Then, push the lever 3091 in the anti-disengagement component 309 upward, causing the insertion rod 3082 to move upward, releasing the restriction of the locking component 308 on the wheel handle 3074 in the locking wheel component 307. Next, the operator rotates the wheel handle 3074, causing the eccentric wheel 3072 to rotate around the shaft 3071. When the wheel handle 3074 rotates to the space between the insertion lever 3081 on the left side of the eccentric wheel 3072, put down the lever 3091. Under the elastic force of the anti-disengagement spring 3092, the insertion rod 3082 moves down and re-engages the wheel handle 3074, restricting its rotation. At the same time, during the rotation of the eccentric wheel 3072, its outer wall engages with the left side of the mounting base 303. The wheel groove 3073 utilizes the radial pressure generated by the eccentric structure to firmly fix the mounting seat 303 in the mounting groove 302, completing the tool installation. When removing the tool, the same method is required: first, push the lever 3091 upward to move the insert rod 3082 upward to unlock the wheel handle 3074, and then rotate the wheel handle 3074 in the opposite direction to disengage the eccentric wheel 3072 from the wheel groove 3073, eliminating the fixing pressure on the mounting seat 303. At this time, the mounting seat 303, along with the tool holder 304 and the tool head 305, can be pulled out along the mounting groove 302 to achieve quick tool removal. The lever 3091 and the anti-disengagement spring 3092 in the anti-disengagement component 309 work together to continuously apply pressure to the insert rod 3082 after the tool is installed and locked, ensuring that the wheel handle 3074 will not rotate on its own due to processing vibration, preventing the tool from accidentally coming loose.

[0049] Furthermore, during the repositioning operation, the operator presses one of the top pressure rods 505 to the left. The pressure rod 505 drives the connected locking block 504 to slide to the left, compressing the return spring 503. This causes the locking block 504 to disengage from the outer wall of the fixed block 501, releasing the locking restriction on the turntable 4. At this time, the turntable 4 is unrestrained and can rotate freely. The operator then rotates the turntable 4, which drives the external cutting tools to rotate synchronously through the fixedly connected multi-position cutting head 301, realizing the tool position switching. When the turntable 4 rotates and the fixed block 501 contacts another locking block 504, the pressure rod 505 is released. Under the elastic restoring force of the return spring 503, the locking block 504 returns to the right and re-engages with the outer wall of the fixed block 501. At this time, the fixed block 501 and the two adjacent locking blocks 504 form a stable locking structure, fixing the turntable 4 and the multi-position cutting head 301 in the current position, completing one tool repositioning.
