[0002] In the printing work of a printer, the printer scraper needs to remove the residual toner and impurities on the surface of the printing plate or the printing roller to ensure that the ink only adheres to the printing area. If the flatness of the printer scraper is insufficient, water droplet-shaped imprints or intermittent line marks may appear on the edge of the printed matter, directly affecting the image clarity. The wear of the scraper will cause frequent problems such as line marks, dirty plates, and color differences, resulting in an increase in the rejection rate and greatly reducing the printing efficiency.

[0003] The printer scraper grinding device is a device specifically used for repairing and maintaining the edge of the printer scraper. Most of the existing printer scraper grinding devices require manual operation. However, manual grinding is prone to uneven edge flatness due to hand shaking or uneven force, affecting the printing resolution and easily causing insufficient precision. It is difficult to maintain a constant grinding angle and pressure during manual operation, resulting in quality fluctuations between batches. Skilled workers take a long time to grind and are difficult to meet the high-frequency maintenance requirements. Therefore, it is necessary to design an automated grinding device for the scraper to solve the above problems. Summary of the Invention

[0007] The present invention further explains that both the first sliding hole and the second sliding hole are right-angled sliding grooves, and both right-angled sides of the first sliding hole are longer than both right-angled sides of the second sliding hole, and a turning hole is further formed at the turning corner of the second sliding hole.

[0008] The present invention further explains that the other ends of each first central shaft are commonly sleeved with a sixth connecting piece, an axis two is glued to the outside of the sixth connecting piece, and the axis two penetrates through the center of another sliding block.

[0009] The present invention further explains that the first driving mechanism includes a first coupling connected to the second telescopic rod, the other end of the first coupling is connected with a first motor, a first motor sleeve is sleeved on the first motor, and the first motor sleeve is fixedly installed on the sliding block; The second driving mechanism includes second motor sleeves fixedly installed at both ends of the fifth connecting piece.

[0011] The present invention further explains that a scraper is suction-connected to one side of the electric suction cup.

[0012] The present invention further explains that a waste residue collection box is arranged below the grinding mechanism in the cover body.

[0013] The present invention further explains the use steps of the grinding device for a scraper, which are characterized in that: S1: Place the scraper to be ground through the material placing hole on one side onto the material placing plate; S2: The output end of the air cylinder on the same side of the scraper is in a contracted state. The placing and taking structure in the feeding mechanism on the same side is at the lowest end. The first telescopic rod extends, drives the electric suction cup to move downward through the fourth connecting piece and suck the scraper, and then the first telescopic rod shortens to the initial length; S3: The air cylinder on the same side extends, pushes the first sliding column through the second connecting piece to drive the placing and taking structure to slide upward in the first sliding hole, and at the same time, the second sliding column on the other side of the placing and taking structure slides in the second sliding hole accordingly; S4: When the placing and taking structure slides to the right-angled position of the first sliding hole and the second sliding hole, the second sliding column slides into the turning hole and then slides out, driving the placing and taking structure to rotate , and at the same time driving the scraper to be converted from a horizontal state to a vertical state; S5: When the cylinder is in a fully extended state, start the second motor close to one side of the scraper. Drive the rough grinding sand roller to rotate through the second coupling and the first central shaft. In the initial state, one side of the rough grinding sand roller is close to the feeding hole. At the same time, the second telescopic rod contracts to drive the entire grinding mechanism to move downward. Meanwhile, the piezoelectric ceramic sheet vibrates, and the vibration is transmitted to the buffer tube through the shape memory alloy helix. The buffer tube evenly disperses and transmits the vibration to the sandpaper layer, and the rough grinding sand roller performs grinding work on one side of the scraper; S6: After the grinding is completed, the second telescopic rod extends to drive the entire grinding mechanism back to the initial position, the second motor is turned off, and the first motor drives the fifth connecting piece to flip through the first coupling and the first shaft , and at the same time, through the connection between the sixth connecting piece and the second shaft, the mechanism between the fifth connecting piece and the sixth connecting piece flips ; S7: Using the same method, complete the grinding work on one side of the scraper by the fine grinding sand roller. After the grinding is completed, the entire grinding mechanism returns to the initial position; S8: At this time, the cylinder of the feeding mechanism close to the material taking hole is in a fully extended state, that is, the electric suction cup is in a vertical state. The two first telescopic rods extend simultaneously, so that the electric suction cup close to the material taking hole tightly adheres to and sucks the other side of the scraper, and the electric suction cup close to the feeding hole releases the scraper. Then, the two first telescopic rods retract to the initial state; S9: Using the same method, use the rough grinding sand roller and the fine grinding sand roller to complete the grinding work on the other side of the scraper in sequence; S10: The cylinder of the feeding mechanism close to the material taking hole contracts. The principle is the same as that of the feeding mechanism in the above steps, but the driving direction is opposite, until the scraper with both sides ground is conveyed and placed on the placing plate, and then taken out.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: In the present invention, (1) By setting the cylinder as the power source, when the cylinder works, its output end extends and contracts, driving the second connecting piece to move. The second connecting piece is slidably connected to the first slide plate through the first slide column, so that the first slide plate moves along the direction of the first slide column. At the same time, the first slide plate drives the second slide column to slide in the second slide hole of the second slide plate through the picking and placing structure, so that the picking and placing structure realizes a specific movement trajectory. The feeding mechanism is respectively beneficial to complete the automatic material picking and placing work; (2) By setting the second telescopic rod to expand and contract according to the thickness of the material, the grinding mechanism is adjusted to a proper height. One of the second motors drives the rough grinding sand roll to rotate for rough grinding through the second coupling and the first central shaft. Then, the first motor drives the fifth connecting piece to flip through the first coupling and the first shaft. Thus, the structures of the two second motors and their driving connections are flipped. After that, the other second motor drives the fine grinding sand roll to rotate through the second coupling and the first central shaft to perform fine grinding on the same side of the material, which is beneficial to the automatic grinding work of the device on the scraper.

[0015] (3) By setting the piezoelectric ceramic sheet to apply an alternating electric field through an external high-frequency signal generator, the piezoelectric ceramic sheet generates radial vibration using its own working mode. This vibration is conducted to the buffer tube through the shape memory alloy spiral. The buffer tube can evenly disperse the vibration energy and conduct it to the sandpaper layer, which can effectively reduce the impact damage to the grinding material. When the sandpaper layer grinds the dirt attached to the surface of the material, if the dirt protrudes too high, the sandpaper layer will squeeze the buffer tube and the shape memory alloy spiral, causing them to undergo elastic deformation to adapt to the shape of the dirt protrusion. After the dirt grinding is completed, both the buffer tube and the shape memory alloy spiral can return to their original shapes, which is beneficial to achieving better adaptive grinding of the material.

Detailed implementation manners

[0017] The technical solution of the present invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0018] Refer to Figures 1 to 9 , the embodiment of the present invention provides a grinding device for a scraper. As Figure 1 shown, the grinding device for a scraper includes a base 1. On both opposite sides of the base 1, side support plates 11 are provided. Taking the two sides of the base 1 where the side support plates 11 are provided as the left and right sides of the device, a feeding mechanism 2 is hinged on each side support plate 11. A grinding mechanism 3 is arranged between the two feeding mechanisms 2 on both sides. A cover body 5 is also arranged on the base 1. Sliding holes 51 are opened on the front and rear sides of the cover body 5, and the two sliding holes 51 are slidably connected with the grinding mechanism 3.

[0019] As Figure 2 and Figure 7As shown, the grinding mechanism 3 includes second telescopic rods 32 fixedly installed respectively below the two sliding holes 51. The upper end of each second telescopic rod 32 is fixedly connected with a sliding block 31. One side of the sliding block 31 is adhesively connected with a first shaft 311. One end of the outer side of the first shaft 311 is connected with a first coupling 312. The other end of the first coupling 312 is connected with a first motor 313. A first motor sleeve 314 is sleeved on the first motor 313. The first motor sleeve 314 is fixedly installed on the sliding block 31.

[0020] As Figure 7 shown, one end of the inner side of the first shaft 311 is connected with a fifth connecting piece 33. Both ends of the fifth connecting piece 33 are fixedly installed with second motor sleeves 331. A second motor 332 is fixedly installed inside each second motor sleeve 331. The other end of each second motor 332 is connected with a second coupling 333. The other end of each second coupling 333 is connected with a first central shaft 334. A rough grinding sand roller 335 is sleeved on one first central shaft 334. A fine grinding sand roller 336 is sleeved on the other first central shaft 334.

[0021] Both the rough grinding sand roller 335 and the fine grinding sand roller 336 include a roller shaft 3341. Piezoelectric ceramic sheets 3342 are evenly pasted along the circumferential direction of the roller shaft 3341. A shape memory alloy helix 3343 is also sleeved on the outer side of the roller shaft 3341. The piezoelectric ceramic sheets 3342 are rigidly connected with the shape memory alloy helix 3343. A buffer tube 3344 is sleeved on the outer side of the shape memory alloy helix 3343. A sandpaper layer 3345 is wrapped on the outer side of the buffer tube 3344. The sandpaper layer 3345 includes coarser sandpaper such as silicon carbide sandpaper and finer sandpaper such as diamond sandpaper. The rough grinding sand roller 335 uses coarser sandpaper. The fine grinding sand roller 336 uses finer sandpaper. The piezoelectric ceramic sheets 3342 achieve a vibration effect through an externally connected high-frequency signal generator.

[0022] When it is necessary to grind the material, the second telescopic rod 32 expands and contracts according to the thickness of the material to adjust the height of the grinding mechanism 3 to a suitable position. One second motor 332 drives the rough grinding sand roller 335 to rotate through the second coupling 333 and the first central shaft 334 for rough grinding. Then, the first motor 313 drives the fifth connecting piece 33 to flip through the first coupling 312 and the first shaft 311 , so that the two groups of second motors 332 and the structures they drive are flipped , and then the other second motor 332 drives the fine grinding sand roller 336 to rotate through the second coupling 333 and the first central shaft 334 to perform fine grinding on the same side of the material.

[0023] During the rough grinding and fine grinding processes, an alternating electric field is applied to the piezoelectric ceramic sheet 3342 through an externally connected high-frequency signal generator. The piezoelectric ceramic sheet generates radial vibration using its own working mode. This vibration is conducted to the buffer tube 3344 through the shape memory alloy helix 3343. The buffer tube 3344 can evenly disperse the vibration energy and conduct it to the sandpaper layer 3345. In this way, during the grinding operation, the impact damage to the grinding material can be effectively reduced. On the premise of being able to effectively conduct vibration, the shape memory alloy helix 3343 also has the following functions: when the sandpaper layer 3345 grinds the dirt attached to the surface of the material, if the dirt protrusion is too high, the sandpaper layer 3345 will squeeze the buffer tube 3344 and the shape memory alloy helix 3343, causing them to undergo elastic deformation to adapt to the shape of the dirt protrusion. After the dirt grinding is completed, both the buffer tube 3344 and the shape memory alloy helix 3343 can return to their original shapes, which is beneficial to achieving better adaptive grinding of the material.

[0024] In some preferred embodiments, as Figures 4 to 6 shown, the feeding mechanism 2 includes a first connecting piece 21 hinged to the side support plate 11. A fixed sleeve 22 is fixed on the upper side of the first connecting piece 21. A cylinder 23 is fixedly arranged inside the fixed sleeve 22. The output end of the cylinder 23 is adhesively connected to a second connecting piece 24. A first sliding column 262 passes through the second connecting piece 24. On one side of the second connecting piece 24, there is a first sliding plate 26. A first sliding hole 261 is formed in the first sliding plate 26. The first sliding column 262 passes through the first sliding hole 261 and is adhesively connected to a picking and placing structure 25. On the other side of the first sliding plate 26, there is a second sliding plate 27. A second sliding hole 271 is formed in the second sliding plate 27. On the other side of the picking and placing structure 25, a second sliding column 272 is adhesively connected. The second sliding column 272 is slidably connected in the second sliding hole 271 of the second sliding plate 27. The outer sides of the first sliding plate 26 and the second sliding plate 27 are commonly connected to a support 28.

[0025] Using the cylinder 23 as the power source, when the cylinder 23 works, its output end expands and contracts, driving the second connecting piece 24 to move. The second connecting piece 24, through the sliding connection of the first sliding column 262 with the first sliding plate 26, causes the first sliding plate 26 to move along the direction of the first sliding column 262. At the same time, the first sliding plate 26 drives the second sliding column 272 to slide in the second sliding hole 271 of the second sliding plate 27 through the picking and placing structure 25, so that the picking and placing structure 25 realizes a specific movement trajectory. The two sets of feeding mechanisms 2 on both sides respectively complete the material picking and placing operations. The grinding mechanism 3 is used to realize the grinding operation.

[0026] AsFigure 5 As shown, the picking and placing structure 25 includes a third connecting piece 251 connected to the first sliding column 262 and the second sliding column 272. One end of the third connecting piece 251 is fixedly connected to a first telescopic rod 252, the other end of the first telescopic rod 252 is fixedly connected to a fourth connecting piece 253, and the other end of the fourth connecting piece 253 is fixedly connected to an electric suction cup 254.

[0027] The third connecting piece 251 plays a key connecting role in the entire picking and placing structure 25. It is connected to the first sliding column 262 and the second sliding column 272, enabling the picking and placing structure 25 to achieve stable linear motion under the drive of the cylinder 23 by means of the guiding action of the first sliding column 262 and the second sliding column 272. By extending and retracting the first telescopic rod 252, the distance between the electric suction cup 254 and the material can be flexibly adjusted, improving the versatility and adaptability of the picking and placing structure 25. The electric suction cup 254 is the component in the picking and placing structure 25 that directly contacts the material, and it uses the negative pressure principle to adsorb the material. When picking up the material, the electric suction cup 254 is in close contact with the surface of the material and generates negative pressure to adsorb the material; when discharging the material, the negative pressure is released, and the material can be separated from the electric suction cup 254.

[0028] In some preferred embodiments, such as Figure 5 and Figure 6 As shown, both the first sliding hole 261 and the second sliding hole 271 are right-angled sliding grooves, and both right-angled sides of the first sliding hole 261 are longer than both right-angled sides of the second sliding hole 271. A steering hole 273 is also provided at the corner of the second sliding hole 271. The first sliding hole 261 and the second sliding hole 271 adopt the design of right-angled sliding grooves. This structure restricts the movement trajectory of the sliding column, enabling the picking and placing structure 25 to slide only along the right-angled path. Both right-angled sides of the first sliding hole 261 are longer than both right-angled sides of the second sliding hole 271, which is beneficial for connecting the picking and placing structure 25 to slide along the sliding groove track through the first sliding column 262 and the second sliding column 272 respectively. When the second sliding column 272 slides to the steering hole 273, its movement trajectory changes, thereby driving the picking and placing structure 25 to rotate. The size and shape of the steering hole 273 are carefully designed to ensure that the second sliding column 272 can smoothly enter and exit, while ensuring the smoothness and accuracy of the rotation action.

[0029] In some preferred embodiments, such as Figure 3 and Figure 7As shown, at the other end of each of the first central axes 334, a sixth connecting piece 34 is sleeved therewith in common. On the outer side of the sixth connecting piece 34, a second shaft 35 is adhesively connected. The second shaft 35 penetrates through the center of another sliding block 31. This is conducive to the overall up-and-down movement of the grinding mechanism 3 and the flipping of the mechanism between the fifth connecting piece 33 and the sixth connecting piece 34.

[0030] In some preferred embodiments, as Figure 3 shown, at the lower end of each of the brackets 28, a material placing plate 6 is fixedly connected. All the material placing plates 6 are fixedly installed on the cover body 5. At the positions corresponding to the air cylinders 23 on each of the material placing plates 6, avoidance holes 61 are formed. The avoidance holes 61 are conducive to ensuring that the air cylinders 23 move along a certain track during the telescopic process without interference with the material placing plates 6.

[0031] In some preferred embodiments, as Figure 1 shown, on the cover body 5, material taking and placing holes 52 are formed on one side of each of the two material placing plates 6. The material taking and placing holes 52 are divided into a material discharging hole and a material taking hole. The sliding block 31 is slidably connected with the sliding hole 51.

[0032] In some preferred embodiments, as Figure 3 shown, on one side of the electric suction cup 254, a scraping knife 4 is suction-connected. Through the negative pressure or vacuum suction force generated by the electric suction cup 254, the scraping knife 4 is firmly adsorbed on the surface of the electric suction cup 254 to realize the fixing work of the scraping knife 4 during grinding and the conveying work of the scraping knife 4.

[0033] In some preferred embodiments, as Figure 3 shown, below the grinding mechanism 3 inside the cover body 5, a waste residue collecting box 7 is arranged. The waste residue collecting box 7 is used for collecting the waste residue falling during grinding.

[0034] In the above embodiments, the use steps of a grinding device for a scraping knife are characterized in that: S1: Place the scraping knife 4 to be ground through the material discharging hole on one side onto the material placing plate 6; S2: The output end of the air cylinder 23 on the same side of the scraping knife 4 is in a contracted state. The material taking and placing structure 25 in the feeding mechanism 2 on the same side is at the lowermost end. The first telescopic rod 252 extends, drives the electric suction cup 254 to move downward through the fourth connecting piece 253 and suck the scraping knife 4, and then the first telescopic rod 252 shortens to the initial length; S3: The cylinder 23 on the same side extends. By pushing the first sliding column 262 through the second connecting piece 24, the picking and placing structure 25 is driven to slide upward in the first sliding hole 261. At the same time, the second sliding column 272 on the other side of the picking and placing structure 25 slides in the second sliding hole 271 accordingly. S4: When the picking and placing structure 25 slides to the right-angle position of the first sliding hole 261 and the second sliding hole 271, the second sliding column 272 slides into the steering hole 273 and then slides out, driving the picking and placing structure 25 to rotate. , and at the same time driving the scraper 4 to switch from the horizontal state to the vertical state. S5: When the cylinder 23 is in the fully extended state, the second motor 332 close to the scraper 4 is started. Through the second coupling 333 and the first central shaft 334, the rough grinding sand roller 335 is driven to rotate. In the initial state, the side of the rough grinding sand roller 335 close to the material discharging hole. At the same time, the second telescopic rod 32 contracts to drive the grinding mechanism 3 to move downward as a whole. At the same time, the piezoelectric ceramic sheet 3342 vibrates, and the vibration is transmitted to the buffer tube 3344 through the shape memory alloy helix 3343. The buffer tube 3344 evenly disperses and transmits the vibration to the sandpaper layer 3345, and the rough grinding sand roller 335 performs the grinding work on one side of the scraper 4. S6: After the grinding is completed, the second telescopic rod 32 extends to drive the grinding mechanism 3 to return to the initial position as a whole. The second motor 332 is turned off, and the first motor 313 drives the fifth connecting piece 33 to flip through the first coupling 312 and the shaft one 311. , and at the same time, through the connection of the sixth connecting piece 34 and the shaft two 35, the mechanism between the fifth connecting piece 33 and the sixth connecting piece 34 is flipped. ; S7: In the same way, the fine grinding sand roller 336 performs the grinding work on one side of the scraper 4. After the grinding is completed, the grinding mechanism 3 returns to the initial position as a whole. S8: At this time, the cylinder 23 of the feeding mechanism 2 close to the material picking hole is in the fully extended state, that is, the electric suction cup 254 is in the vertical state. The two first telescopic rods 252 extend simultaneously, so that the electric suction cup 254 close to the material picking hole tightly adheres to and sucks the other side of the scraper 4, and the electric suction cup 254 close to the material discharging hole releases the scraper 4. Then, the two first telescopic rods 252 retract to the initial state. S9: In the same way, the rough grinding sand roller 335 and the fine grinding sand roller 336 are used in turn to complete the grinding work on the other side of the scraper 4. S10: The air cylinder 23 of the feeding mechanism 2 near the material taking hole contracts. The principle is the same as that of the feeding mechanism 2 in the above steps, but the driving direction is opposite. It is until the scraper 4 polished on both sides is conveyed and placed on the material placing plate 6, and then taken out.

9. The use steps of a grinding device for a scraper according to any one of claims 1-8, characterized in that: S1: Place the scraper to be ground through the feeding hole on one side onto the material placing plate; S2: The output end of the cylinder on the same side of the scraper is in a contracted state. The taking and placing structure in the feeding and discharging mechanism on the same side is at the lowest end. The first telescopic rod extends, drives the electric suction cup to move downward through the fourth connecting piece and suck the scraper, and then the first telescopic rod shortens to the initial length; S3: The cylinder on the same side extends, pushes the first sliding column through the second connecting piece to drive the taking and placing structure to slide upward in the first sliding hole, and at the same time the second sliding column on the other side of the taking and placing structure slides in the second sliding hole; S4: When the picking and placing structure slides to the right-angle position of the first sliding hole and the second sliding hole, the second sliding column slides into the steering hole and then slides out, driving the picking and placing structure to rotate , and at the same time driving the scraper to switch from a horizontal state to a vertical state; S5: When the cylinder is in a fully extended state, start the second motor close to one side of the scraper. Drive the coarse grinding sand roller to rotate through the second coupling and the first central shaft. In the initial state, the side of the coarse grinding sand roller close to the feeding hole. At the same time, the second telescopic rod contracts to drive the whole grinding mechanism to move downward, and at the same time the piezoelectric ceramic sheet vibrates. The vibration is transmitted to the buffer tube through the shape memory alloy helix. The buffer tube evenly disperses and transmits the vibration to the sandpaper layer.
