[0002] The surface quality of the printing sheet, as the core component of the printing machine, directly affects the printing accuracy and stability. Traditional printing sheet surface treatment devices usually adopt a one-way grinding process, which has the following technical bottlenecks.

[0003] According to the technical effects of existing technologies and technical solutions, there are still areas that need to be optimized: 1. Grinding efficiency and precision issues: Existing devices mostly use a single-direction moving grinding head, which results in a single surface texture direction, making it difficult to eliminate burrs and dents, and requires multiple reciprocating processes, which takes a long time; 2. Insufficient automation: Traditional equipment requires manual intervention when switching between rough grinding and fine grinding, and cannot achieve continuous processing, resulting in low efficiency and the processing accuracy is affected by human operation; 3. Limited debris processing capacity: The metal debris generated during the grinding process is easy to splash or accumulate, and the existing dust collection device is difficult to effectively collect it, which affects the working environment and poses a safety hazard.

A rough grinding ring 205g and a fine grinding ring 205h are respectively arranged at both ends of the top of the rotating rod 205f; Triangular plates 401 are in contact with the surface of the support ring 105f. There are two triangular plates 401. Cross bars 402 are arranged on the opposite sides of the two triangular plates 401. A first spring 403 is arranged on the surface of the cross bar 402. A clamping block 404 is arranged on one side of the first spring 403, and the bottom of the clamping block 404 is fixedly connected to the top of the support plate 100; Travel rods 405 are provided at the tops of the triangular plates 401. A travel groove 406 is formed on the surface of the travel rod 405. An extension groove 407 is formed on the surface of the travel groove 406. Connecting columns 408 are slidably connected to the surfaces of both the extension groove 407 and the travel groove 406. The left side of the connecting column 408 penetrates through the inside of the adjustment plate 205b and is fixedly connected to the right side of the grinding rod 205d;A positioning rod 409 is provided on the outer side of the grinding rod 205d. The left side of the positioning rod 409 penetrates into the interior of the grinding rod 205d and contacts the surface of the positioning groove 410. The positioning groove 410 is formed on the surface of the annular groove 410a. A positioning plate 411 is provided on the right side of the positioning rod 409. Two auxiliary rods 412 penetrate through the left and right sides of the positioning plate 411. The left sides of the two auxiliary rods 412 are fixedly connected to the outer side of the grinding rod 205d. Second springs 413 are sleeved on the surfaces of the two auxiliary rods 412. The right sides of the second springs 413 are fixedly connected to the left side of the positioning plate 411. The left side of the end of the positioning rod 409 in contact with the positioning groove 410 is circular arc-shaped; an extrusion column 414 is provided at the bottom of the rotating column 205e. A torsion spring 415 is sleeved on the surface of the extrusion column 414. The upper and lower sides of the torsion spring 415 are fixedly connected to the bottom of the grinding rod 205d and the top of the extrusion column 414 respectively; an extrusion block 416 is provided on the right side of the positioning plate 411. An extrusion plate 417 is provided on the top of the extrusion block 416. The top of the extrusion plate 417 is fixedly connected to the bottom of the annular plate 301; a matching column 418 is provided at the bottom of the extrusion column 414. The bottom of the matching column 418 is fixedly connected to the top of the support plate 100.;

[0038] Specifically, the thread directions of the two screw rods 204 are opposite. The left screw rod 204 has a right-handed thread, and the right screw rod 204 has a left-handed thread. When the output motor 203 drives the pulley 202 group to rotate, the two screw rods 204 rotate synchronously and in opposite directions, causing the adjusting block 205a to move towards or away from each other along the inner side of the fixed column 201. The adjusting block 205a drives the adjusting plate 205b and the grinding rod 205d to move axially along the printing roller. The rough grinding ring 205g and the fine grinding ring 205h are respectively located at both ends of the rotating rod 205f, forming a cross-grinding track during the movement. When the adjusting block 205a reaches the limit position at the bottom of the screw rod 204, the circular arc-shaped end of the positioning rod 409 contacts the positioning groove 410 of the annular groove 410a. At this time, the extrusion column 414 contacts the matching column 418, causing the annular groove 410a to squeeze the positioning rod 409 out of the positioning groove 410 and driving the rotating column 205e to rotate 180° under the influence of the stroke of the annular groove 410a, realizing the automatic switching between the rough grinding ring 205g and the fine grinding ring 205h.

[0039] Furthermore, the stroke rod 405 slides in the stroke groove 406 and drives the connecting column 408 to move synchronously through the extension groove 407, ensuring a constant grinding pressure. The extrusion block 416 on the right side of the positioning plate 411 and the extrusion plate 417 at the bottom of the annular plate 301 form a mechanical limit. When the grinding assembly 205 reaches the limit position, the extrusion block 416 contacts the extrusion plate 417 to trigger the unlocking of the positioning rod 409, providing the initial power for the rotation of the rotating column 205e.

[0040] It should be noted that when the printing roller is polished, it rotates counterclockwise first and then clockwise. When rotating counterclockwise, it is for rough polishing of the rough polishing ring 205g, and when rotating clockwise, it is for fine polishing of the fine polishing ring 205h.

[0041] Embodiment 3 Refer to Figure 1 、 3 、5 - 9, which is the third embodiment of the present invention, and provides a dust suction mechanism 300.

[0042] The dust suction mechanism 300 includes an annular plate 301 disposed on one side of the support column 101. A dust suction pump 302 is provided at the top of the annular plate 301. The output end of the dust suction pump 302 penetrates to the bottom of the annular plate 301. The top of the output motor 203 is fixedly connected to the bottom of the annular plate 301. A connecting pipe 303 is provided at the discharge end of the dust suction pump 302. A telescopic hose 304 is provided at the bottom of the connecting pipe 303. The bottom of the telescopic hose 304 is communicated with a collection box 305. A cutting assembly 306 is provided on the surface of the telescopic hose 304; the cutting assembly 306 includes an inclined plate 306a communicated with the surface of the telescopic hose 304. The right side of the inclined plate 306a penetrates to one side of the support column 101. Guide grooves 306b are provided on both the left and right sides of the support column 101. A second push rod 306c is provided on the surface of the guide groove 306b. The output end of the second push rod 306c is drivingly connected to the top of the inclined plate 306a. A driving member 306d is provided at the top of the inclined plate 306a. A cutting member 306e is provided at the output end of the driving member 306d; a slow - elastic groove 419 is provided on the right side of the inclined plate 306a. A third spring 420 is provided on the surface of the slow - elastic groove 419. An extension plate 421 is provided on the right side of the third spring 420. A closing plate 422 is provided on the right side of the extension plate 421. The right side of the cutting member 306e penetrates to the right side of the closing plate 422. Three magnetic attraction blocks 423 of different sizes are arranged on the inner side of the extension plate 421, and the right side of the closing plate 422 is in a vertical state and fits the surface of the printing roller.

[0043] Specifically, the second push rod 306c pushes the inclined plate 306a to move vertically along the guide groove 306b. The closing plate 422 on the right side of the inclined plate 306a always fits the surface of the printing roller under the action of the third spring 420. The three magnetic attraction blocks 423 on the inner side of the extension plate 421 are arranged in decreasing order of diameter, generating a gradient magnetic field: the large - size magnetic attraction blocks 423 adsorb larger metal debris, the small - size magnetic attraction blocks 423 adsorb fine particles, and the medium - size magnetic attraction blocks 423 enhance the adsorption effect in the transition area. The right side of the closing plate 422 is vertically designed and forms a line contact with the surface of the printing roller, effectively blocking the splashing of debris.

[0044] Furthermore, since the inclined plate 306a is arranged in an inclined shape, during the movement of the inclined plate 306a after completion or during subsequent grinding, the device generates a little vibration, enabling debris to enter the telescopic hose 304 through the inclined plate 306a. Due to the connection relationship between the telescopic hose 304 and the connecting pipe 303, the fine waste chips discharged during grinding and the wind force can boost the cutting debris, preventing blockage.

[0045] It should be noted that the magnetic attraction block 423 is electrically controlled, that is, an electromagnetic attraction block 423.

[0046] The remaining structure is the same as that of Embodiment 2.

[0047] Embodiment 4 Refer to Figures 1 to 9 , which is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment provides a surface treatment device for manufacturing a printing roller.

[0048] When using this device; First, the electric cylinder 103 drives the output component 104 to move horizontally in the transmission slot 102 of the support plate 100 to adjust the processing position of the printing roller. The first motor 104b in the output component 104 drives the clamping component 105 to rotate. The first push rod 105b in the fixed seat 105a pushes the push column 105c, causing the clamping rod 105d and the rotating plate 105e to form a linkage. The inner side of the printing roller is tightly clamped by the outer side of the rotating plate 105e. At the same time, the support ring 105f contacts the inner wall of the printing roller to form three-point support, ensuring the rotation stability. The triangular plate 401 on the outer side of the support ring 105f is elastically connected to the block 404 through the cross bar 402 and the first spring 403, which can adapt to printing rollers of different diameters and eliminate the problem of clamping stress concentration caused by pipe diameter differences; The core of the grinding mechanism 200 lies in the reverse drive design of the double screw 204. The output motor 203 drives the pulley 202 group, causing the two screws 204 to rotate in opposite directions (for example, the left screw 204 rotates counterclockwise and the right screw 204 rotates clockwise). The adjustment block 205a is meshed with the screw 204 through a thread. When the screw 204 rotates, the adjustment block 205a moves synchronously up and down in the fixed column 201, driving the adjustment plate 205b and the grinding component 205 to move in the opposite direction along the axial direction of the printing roller. This design enables the rough grinding ring 205g and the fine grinding ring 205h to form a grinding trajectory moving towards each other during the movement, eliminating the pattern directionality of traditional one-way grinding through the superposition of movements and significantly improving the surface finish; When the grinding assembly 205 moves to the extreme position of the screw 204, since the left side of the contact end of the positioning rod 409 and the positioning groove 410 is set in an arc shape, when the left screw 204 reaches the bottom, it is squeezed by the matching column 418, so that the rotating column 205e is rotated by the stroke of the annular groove 410a. When the rotating column 205e rotates, the positioning rod 409 is squeezed and separated from the positioning groove 410 and contacts the surface of the annular groove 410a. At this time, the squeezing column 414 contacts the matching column 418, and the annular groove 410a drives the rotating column 205e to rotate, so that the coarse grinding ring 205g and the fine grinding ring 205h are completely polished. The rough grinding ring 205g and the fine grinding ring 205h are switched by 180° to realize the automatic transition between rough and fine machining, and the torsion spring 415 is given a torque when the rotating ring rotates. The rotation degree of the annular groove 410a is 180°, and the two ends of the annular groove 410a are provided with positioning grooves 410; when the rough grinding ring 205g and the fine grinding ring 205h move to the opposite position again, the extrusion plate 417 and the extrusion block 416 cooperate to make the positioning rod 409 separate from the surface of the positioning groove 410 again, and the reverse torque of the torsion spring 415 makes the rough grinding ring 205g and the fine grinding ring 205h complete the 180° switch again, thereby ensuring the stability of the switching; The dust suction mechanism 300 generates negative pressure through the dust suction pump 302 on the annular plate 301, and sucks the grinding debris into the collection box 305 through the connecting pipe 303 and the telescopic hose 304. The cutting assembly 306 is integrated on the telescopic hose 304. The second push rod 306c pushes the inclined plate 306a to move along the guide groove 306b to adjust the vertical position of the cutting member 306e. When cutting is required, the driving member 306d can be controlled to drive the cutting member 306e to perform cutting work. The closing plate 422 on the right side of the inclined plate 306a is always in contact with the surface of the printing roller under the action of the third spring 420. The magnetic suction blocks 423 of different sizes arranged on the inner side thereof generate a gradient magnetic field, which forms a differentiated adsorption force on the metal chips generated by cutting. Large particles of debris are adsorbed on the surface of the closing plate 422 by the strong magnetic field, and small particles are sucked into the hose, which effectively avoids debris splashing and improves the collection efficiency. The slow elastic structure of the closing plate 422 can also buffer the cutting force to prevent surface damage caused by rigid contact. Since the inclined plate 306a is set to an inclined shape, the device will produce a slight vibration during the movement of the inclined plate 306a after completion or during subsequent grinding, so that the debris can enter the telescopic hose 304 through the inclined plate 306a, and through the communication relationship between the telescopic hose 304 and the connecting pipe 303, the cutting debris can be pushed forward by the fine waste chips discharged during grinding and the action of wind to prevent blockage.

[0049] In summary: through the counterclockwise and clockwise design of the printing roller, all parts of the surface of the printing roller can be polished more evenly, reducing the directionality of the polishing lines, improving the surface flatness and smoothness, thereby improving the overall polishing quality of the printing roller.
