Description

Technical Field

[0001] This utility model relates to the field of printing roller engraving, specifically to a high-definition laser printing roller engraving device for line supplementation. Background Technology

[0002] Chinese Patent No. CN219189002U discloses a high-definition laser roller engraving device for line filling, including a base. A motor is fixedly mounted on the surface of one end of the base. A rotating shaft is mounted on the output end of the motor. One end of the rotating shaft passes through the base and is mounted with a fixed clamping plate. A lead screw is rotatably connected to the fixed clamping plate inside the base. A motor is fixedly mounted on the surface of the other end of the base. The output end of the motor passes through the base and is fixedly connected to the lead screw. A threaded block is threadedly connected to the surface of the lead screw. A connecting shaft is fixedly mounted on one end of the threaded block. A movable clamping plate is rotatably connected to one end of the connecting shaft. An air extraction mechanism is installed above the base.

[0003] The aforementioned laser printing roller engraving device uses a motor to rotate a lead screw, which in turn moves a threaded block. The threaded block then moves a movable clamping plate, allowing printing rollers of various lengths to be fixed between a fixed clamping plate and a movable clamping plate. This facilitates the fixing of printing rollers of different lengths, making the process convenient and quick, and effectively accelerating the cutting efficiency of the printing rollers.

[0004] However, several shortcomings still exist in practical applications. In particular, when clamping the printing roller, the system cannot quickly and accurately position the roller's axis (i.e., it cannot quickly ensure that the roller's axis is perfectly aligned with the shaft's axis), which may lead to significant deviations during the engraving process, and in severe cases, even render the entire roller unusable. Furthermore, the loading and unloading of the printing roller still requires manual handling and lifting, a process that is not only physically demanding but also poses certain safety risks. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a high-definition laser printing roller engraving device with a line-filling type, which can quickly position the roller axis and thus ensure processing accuracy.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; 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 refer to the internal communication of two components or the interaction between 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.

[0028] like Figures 1-4 This utility model provides a high-definition laser printing roller engraving device with a line-filling type, including a frame 1, a support frame 101 fixedly installed on the top of the frame 1, an X-axis drive mechanism 2 provided on the support frame 101, a Y-axis drive mechanism 3 installed on the moving end of the X-axis drive mechanism 2, a mounting base 4 installed on the moving end of the Y-axis drive mechanism 3, a laser engraving head 5 fixedly installed on the mounting base 4, a rotary clamping mechanism 8 for concentrically positioning and clamping the printing roller and driving it to rotate is installed on the frame 1 through a spacing adjustment mechanism 7, and a lifting mechanism 9 for lifting the printing roller is provided on the frame 1.

[0029] Specifically, in this embodiment, the X-axis drive mechanism 2 includes a first linear module, which is fixedly mounted on the support frame 101. The Y-axis drive mechanism 3 includes a second linear module, which is fixedly mounted on the slide of the first linear module. The mounting base 4 is fixedly mounted on the slide of the second linear module. The first linear module, in conjunction with the second module, can drive the laser engraving head 5 to move along the X-axis and Y-axis. In use, the first linear module drives the laser engraving head 5 to move back and forth along the X-axis, thereby enabling engraving at different positions on the printing roller. The second linear module drives the laser engraving head 5 to move up and down along the Y-axis, thereby enabling engraving on printing rollers of different diameters.

[0030] In this embodiment, a dust collection hood 6 is fixedly installed on the mounting base 4 to absorb and collect the dust generated during the laser engraving head 5 engraving. The negative pressure port of the dust collection hood 6 is connected to the air inlet of the suction pump through a pipeline. The dust collection hood 6 can absorb the dust generated during the laser engraving head 5 engraving, thus preventing the processing environment from being polluted.

[0031] In this embodiment, the spacing adjustment mechanism 7 includes a first drive motor 701 and a lead screw 702. The threads at both ends of the lead screw 702 are arranged in opposite directions. The first drive motor 701 is fixedly mounted on the frame 1, and the lead screw 702 is rotatably mounted on the frame 1 via a stand block 705. One end of the lead screw 702 is fixedly connected to the shaft of the first drive motor 701. A slide rail 704 is fixedly mounted on the frame 1. Both ends of the lead screw 702 are threadedly rotatably connected to a movable seat 706. A first slider 703 is fixedly mounted on the bottom of the movable seat 706 and is slidably mounted. On the slide rail 704, the rotary clamping mechanism 8 includes a second motor 801. The upper ends of the two movable seats 706 are rotatably mounted with rotating shafts 802. One end of the rotating shaft 802 is fixedly mounted with a U-shaped frame 803. The inner side of the U-shaped frame 803 is rotatably mounted with a threaded rod 805. The two ends of the threaded rod 805 are arranged with opposite threads. Both ends of the threaded rod 805 are threadedly rotatably connected with clamping blocks 804. The second motor 801 is fixedly mounted on one side of one of the movable seats 706. The rotating shaft of the second motor 801 is fixedly connected to one end of one of the rotating shafts 802.

[0032] By adopting the above technical solution, when clamping the printing roller, the printing roller is placed between two movable seats 706, and then the first drive motor 701 is started to drive the lead screw 702 to rotate clockwise, thereby driving the two C-shaped frames 803 to move towards each other, placing the rotating shaft at the end of the printing roller between two clamping blocks 804. Then the threaded rod 805 is rotated clockwise, thereby causing the two clamping blocks 804 to move towards each other, clamping the rotating shaft at the end of the printing roller between the two clamping blocks 804. The clamping steps for the rotating shaft at the other end of the printing roller are the same as the above steps, and will not be repeated here. Then the second motor 801 is started to drive the printing roller to rotate.

[0033] When disassembling the printing roller, first rotate the threaded rod 805 counterclockwise so that the clamping block 804 releases its grip on the end shaft of the printing roller. Then, control the first drive motor 701 to drive the lead screw 702 to rotate counterclockwise, thereby causing the two C-shaped frames 803 to move in opposite directions. At this time, the printing roller can be removed.

[0034] In this embodiment, in order to ensure that the clamping block 804 can move up and down stably, a sliding groove 8031 ​​is provided on the inner side of the shaped frame 803, and a second slider 8041 is fixedly connected to one end of the clamping block 804. The second slider 8041 is slidably disposed in the sliding groove 8031.

[0035] In this embodiment, the lifting mechanism 9 includes an electric push rod 901, which is fixedly installed on the inner top of the frame 1. The piston rod of the electric push rod 901 slides through the top of the frame 1 and is fixedly connected to the lifting plate 902. In order to prevent the plate roller from detaching from the lifting plate 902, V-shaped seats 903 are fixedly connected to both ends of the lifting plate 902.

[0036] With the above settings, when installing the printing roller, the printing roller is placed on the support plate 902, and then the piston rod of the electric push rod 901 is extended to drive the printing roller to move upward. When the printing roller reaches the preset height, the electric push rod 901 stops. After the printing roller is fixed, the piston rod of the electric push rod 901 is retracted to reset the support plate 902, so that the support plate 902 does not affect the printing roller during engraving.

[0037] When disassembling the printing roller, the piston rod of the electric push rod 901 is extended so that the lifting plate 902 can lift the lower end of the printing roller, and then the printing roller can be disassembled. During the disassembly process, the printing roller is lifted, thus effectively preventing the printing roller from accidentally falling during disassembly.

[0038] In summary, the spacing adjustment mechanism 7, in conjunction with the rotating clamping mechanism 8, can clamp rollers of different lengths. Moreover, during clamping, the roller axis can be quickly positioned, ensuring that the roller axis and the axis of the rotating shaft 802 are on the same straight line, thereby ensuring engraving accuracy.

[0039] The X-axis drive mechanism 2, in conjunction with the Y-axis drive mechanism 3, can drive the laser engraving head 5 to move along the X-axis and Y-axis, enabling the laser engraving head 5 to engrave on printing rollers of different diameters.

[0040] The lifting mechanism 9 can lift the printing roller during installation and removal without the need for manual lifting.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
