Description

Technical Field

[0001] This invention relates to the field of printing roller processing equipment, and more specifically to a high-precision structural printing roller grinding machine. Background Technology

[0002] Printing rollers are divided into hollow rollers and solid rollers, and rollers with shafts and rollers without shafts. They are generally used for plate making. In practical applications, the surface of the printing roller needs to be ground with high precision before it can be put into use. During the grinding process, rollers of different lengths are generally positioned by the roller positioning mechanism of the roller grinding machine, and then driven to rotate by the motor. Then, the grinding mechanism polishes the surface of the roller to a smooth surface to obtain a roller with a smooth surface.

[0003] Chinese utility model patent application CN201721683706.8 discloses a printing plate roller grinding machine, specifically including a frame, a main grinding head, a grinding head guide rail, and a main grinding motor. The main grinding base is mounted on the grinding head guide rail, and the main grinding motor is mounted on the main grinding base. A grinding head translation motor is mounted on the frame and is drivenly connected to the main grinding base. Printing plate roller mounting brackets are respectively mounted on both ends of the frame. A coarse grinding head base is also mounted on the grinding head guide rail. The power output shaft of the grinding head translation motor is drivenly connected to the coarse grinding head base. A coarse grinding motor is mounted on the coarse grinding head base, and the power output shaft of the coarse grinding motor is connected to the coarse grinding head. Elastic elements are also provided on both sides of the power output shaft. The two ends of the elastic elements are respectively connected to the coarse grinding motor and the coarse grinding head, so that the coarse grinding head vibrates slightly relative to the printing plate roller, avoiding over-grinding of the printing plate roller by the coarse grinding head in one go, which would lead to a lot of fine grinding and repair work in the later stage, thus improving the stability and efficiency of coarse grinding.

[0004] Existing printing plate roller grinding machines are not convenient for precise adjustment according to the diameter of the printing plate roller. During use, the water used for cooling is prone to spraying out and is not easy to intercept. In addition, the manufacturing cost is high, which is not conducive to improving the economic benefits of enterprises.

[0005] Therefore, it is necessary to invent a high-precision printing plate roller grinding machine to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-precision printing plate roller grinding machine. Through an adjustable distance module, the distance between the grinding module and the printing plate roller can be precisely adjusted as needed, improving the applicability of the device.

[0008] In a preferred embodiment of the present invention, one of the active rotating rollers has a first active tooth fixedly connected to its end, and the other active rotating roller has a second active tooth fixedly connected to its end. A servo motor is installed at the input end of the active rotating roller.

[0010] As a preferred embodiment of the present invention, the inner wall of the protective housing is provided with through holes on both sides to cooperate with the active rotating roller, and control cavities are provided inside both sides of the protective housing.

[0011] As a preferred embodiment of the present invention, the disassembly plate near the worm gear is provided with a sliding groove adapted to the fan-shaped limiting groove, and the side of the sliding groove is provided with scale lines. The sleeve extends to the outside of the disassembly plate, and a pointer is fixedly connected to the end of the sleeve.

[0012] As a preferred embodiment of the present invention, a longitudinal slider is fixedly connected to the rear side of the limiting plate, a longitudinal limiting groove adapted to the longitudinal slider is opened on the rear side of the inner wall of the protective shell, a thread is provided on the outer side of the lead screw, and a crossbeam is rotatably connected to both sides of the thread, and both crossbeams are fixedly connected to the limiting plate.

[0013] In a preferred embodiment of the present invention, the grinding assembly is threadedly connected to the lead screw, a transverse slider is fixedly connected to the rear side of the grinding assembly, a protrusion is fixedly connected to the outer side of the transverse slider, and a transverse limiting groove adapted to the protrusion is provided inside the limiting plate.

The active rotating roller drives the lead screw to rotate through the adjusting connecting rod. The lead screw drives the grinding component to slide laterally. By starting the grinding motor, the grinding head is driven to rotate, thereby grinding the surface of the printing plate roller. This saves power and helps to save manufacturing costs. 2. By starting the precision motor, the precision motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. This causes the adjusting connecting rod to slide inside the sector-shaped limiting groove. The adjusting connecting rod, through the second and third connecting rods, pulls the lead screw to move up and down inside the lifting limiting groove, thereby adjusting the distance between the lead screw and the clamping part. This allows for precise adjustment of the distance between the grinding module and the printing roller as needed, improving the applicability of the device. While the worm wheel rotates, it drives the sleeve to slide inside the slide groove, causing the pointer at the end of the sleeve to swing. Users can observe the rotation angle of the pointer through the scale lines, allowing for further precise adjustment of the distance. 3. During use, users can inject water into the water inlet pipe so that the water is sprayed onto the grinding head through the spray pipe, thereby reducing the heat generated during the grinding process and protecting the printing roller. At the same time, the baffle can block the sprayed water and block the rear of the device, avoiding water splashing and the inconvenience to the workers. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This invention provides, for example Figure 1-9 The high-precision printing plate roller grinding machine shown includes a protective module for supporting and protecting the device, a clamping module for clamping and driving the printing plate roller, a grinding module for grinding the surface of the printing plate roller, a distance adjustment module for adjusting the distance between the grinding module and the printing plate roller according to the diameter of the printing plate roller, and a cooling module for cooling the printing plate roller. The protective module includes a protective shell 1, the clamping module includes a clamping component 2, the distance adjustment module includes an adjusting connecting rod 3 and a lead screw 4, the grinding module includes a grinding component 5 and a limiting plate 6, and the cooling module includes a water inlet pipe 8. Control cavities 101 are opened inside both sides of the protective shell 1, and a disassembly plate 7 is detachably connected to both sides of the protective shell 1 by screws. The clamping member 2 is used to clamp the printing plate roller. Both sides of the clamping member 2 are fixedly connected with active rotating rollers 201. One active rotating roller 201 is fixedly connected to the end of one active rotating roller 201 and the other active rotating roller 201 is fixedly connected to the end of the other active rotating roller 201. A servo motor 204 is installed at the input end of the active rotating roller 201. One end of the adjusting connecting rod 3 is fixedly connected to a first transmission tooth 301 that meshes with the first driving tooth 202, and the other end of the adjusting connecting rod 3 is fixedly connected to a second transmission tooth 302 that meshes with the second driving tooth 203. One end of the lead screw 4 is fixedly connected to a first driven tooth 401 that meshes with the first transmission tooth 301, and the other end of the lead screw 4 is fixedly connected to a second driven tooth 402 that meshes with the second transmission tooth 302. Specifically, the user can clamp the printing plate roller to be ground inside the clamping member 2, and then start the servo motor 204. The servo motor 204 drives the active rotating roller 201 to rotate, which in turn drives the printing plate roller to rotate. The active rotating roller 201 drives the first active tooth 202 and the second active tooth 203 to rotate. The first active tooth 202 drives the first driven tooth 401 to rotate through the first transmission tooth 301, and the second active tooth 203 drives the second driven tooth 402 to rotate through the second transmission tooth 302. This causes the lead screw 4 to rotate, and the lead screw 4 drives the grinding component 5 to slide laterally, thereby grinding the surface of the printing plate roller. The clamping member 2 and the lead screw 4 are linked, saving power and reducing equipment processing costs.

[0021] A first connecting rod 303 is provided on the side of the second driving tooth 203 and the second transmission tooth 302. The driving roller 201 and the adjusting connecting rod 3 are rotatably connected to the first connecting rod 303. A second connecting rod 403 is provided on the side of the first transmission tooth 301 and the first driven tooth 401. A third connecting rod 404 is provided on the side of the second transmission tooth 302 and the second driven tooth 402. The adjusting connecting rod 3 and the lead screw 4 are rotatably connected to the second connecting rod 403 and the third connecting rod 404.

[0022] In the above structure, a worm gear 306 is coaxially arranged on the side of the active rotating roller 201. The worm gear 306 is rotatably connected to the active rotating roller 201, and a sleeve 304 is fixedly connected to the side of the worm gear 306. The sleeve 304 is rotatably connected to the adjusting connecting rod 3. A precision motor 307 is installed below the worm gear 306, and a worm 308 that meshes with the worm gear 306 is fixedly connected to the output end of the precision motor 307.

[0023] Specifically, when a specific distance adjustment of the device is required, the user can start the precision motor 307, which drives the worm gear 308 to rotate. The worm gear 308 drives the worm wheel 306 to rotate, thereby causing the adjusting connecting rod 3 to slide inside the fan-shaped limiting groove 103. The adjusting connecting rod 3 pulls the lead screw 4 to move up and down inside the lifting limiting groove 104 through the second connecting rod 403 and the third connecting rod 404, thereby adjusting the distance between the lead screw 4 and the clamping part 2. This allows for precise adjustment of the distance between the grinding module and the printing roller as needed, improving the applicability of the device.

[0024] For example Figure 7 As shown, the inner wall of the protective housing 1 has through holes 102 that cooperate with the active rotating roller 201, a sector-shaped limiting groove 103 that cooperates with the adjusting connecting rod 3, and a lifting limiting groove 104 that cooperates with the lead screw 4. In use, the active rotating roller 201 rotates inside the through hole 102, the lead screw 4 slides inside the lifting limiting groove 104, and the adjusting connecting rod 3 slides inside the sector-shaped limiting groove 103, which helps to limit the device and prevent the parts from shifting.

[0025] As a further optimization of the present invention, the disassembly plate 7 near the worm gear 306 is provided with a sliding groove 701 that matches the fan-shaped limiting groove 103, and the sliding groove 701 is provided with a scale line 702 on its side. The sleeve 304 extends to the outside of the disassembly plate 7, and the end of the sleeve 304 is fixedly connected to a pointer 305. When the worm gear 306 rotates, it can drive the sleeve 304 to slide inside the sliding groove 701, thereby causing the pointer 305 at the end of the sleeve 304 to swing. The user can observe the rotation angle of the pointer 305 through the scale line 702 and can further adjust the distance more precisely.

[0026] like Figure 5 and Figure 6 As shown, a longitudinal slider 602 is fixedly connected to the rear side of the limiting plate 6. A longitudinal limiting groove 105 adapted to the longitudinal slider 602 is opened on the rear side of the inner wall of the protective shell 1. The outer side of the lead screw 4 is provided with threads, and crossbeams 604 are rotatably connected to both sides of the threads. Both crossbeams 604 are fixedly connected to the limiting plate 6. When the device is adjusting the distance, the lead screw 4 moves up and down in the lifting limiting groove 104, which in turn drives the limiting plate 6 to move up and down through the crossbeams 604. The longitudinal slider 602 on the rear side of the limiting plate 6 slides inside the longitudinal limiting groove 105, which can improve the stability of the device.

[0027] In the above structure, the grinding component 5 is threadedly connected to the lead screw 4. A transverse slider 501 is fixedly connected to the rear side of the grinding component 5. A protrusion 502 is fixedly connected to the outer side of the transverse slider 501. A transverse limiting groove 601 that matches the protrusion 502 is opened inside the limiting plate 6. When the lead screw 4 rotates, it can drive the grinding component 5 to slide laterally on the lead screw 4, thereby driving the protrusion 502 fixedly connected to the outer side of the transverse slider 501 to slide in the transverse limiting groove 601 inside the limiting plate 6, which can limit the grinding component 5.

[0028] like Figure 8 As shown, a grinding motor is installed at the bottom of the grinding assembly 5, and a grinding head 503 is fixedly connected to the output end of the grinding motor. The grinding head 503 is located directly above the clamping member 2. By starting the grinding motor, the grinding head 503 is driven to rotate, thereby grinding the printing roller.

[0029] In a further optimization of the above embodiment, in order to cool down the printing roller and prevent excessive temperature from damaging the material, the water inlet pipe 8 is located behind the horizontal slider 501, and water spray pipes 801 connected to the water inlet pipe 8 are provided on both sides of the grinding head 503. The water spray pipes 801 are inclined towards the grinding head 503. A water collection tank 106 is provided at the bottom of the inner side of the protective housing 1. The side of the water collection tank 106 is connected to the water outlet 803. During use, the user can inject water into the water inlet pipe 8, so that the water is sprayed onto the processing position of the grinding head 503 through the water spray pipes 801, thereby reducing the heat generated during the grinding process and protecting the printing roller. The sprayed water naturally falls into the water collection tank 106 and flows out through the water outlet 803, which is conducive to the centralized treatment of water.

[0030] In the above structure, a water baffle 802 is fixedly connected to the front side of the grinding component 5, and a baffle 603 is fixedly connected to the bottom of the limiting plate 6. During the spraying process, the water baffle 802 can block the sprayed water and prevent water from splashing out of the device. The baffle 603 can block the rear side of the device to avoid water splashing, which is not good for the staff. The water baffle 802 moves with the movement of the grinding component 5 and can always block the side of the water spray pipe 801.

[0031] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
