Description

Technical Field

[0001] The invention belongs to the technical field of roller surface repair, and in particular relates to a roller surface polishing device. Background Art

[0002] The roller press is designed based on the principle of material bed grinding. It consists of two rotating rollers. The material is put in from above the two rollers and is continuously brought between the two rollers by the rollers. After being highly squeezed, it becomes a dense cake and is discharged from the bottom of the rollers. In addition to a certain proportion of fine-grained finished products, the discharged cake has a large number of cracks inside the non-finished particles due to the high-intensity squeezing pressure. At this time, the rollers need to be polished and repaired.

[0003] Traditional roller polishing is to clamp the roller with a clamp, and then use a polishing machine to polish and repair the roller surface. After the repair is completed, the roller needs to be released and rotated to polish and repair other parts. When the roller surface is worn in many places, this method requires repeated clamping, releasing and rotating of the roller to complete the roller surface repair, which greatly reduces the efficiency of roller polishing. To this end, we provide a roller surface polishing device to solve the above problems. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention drives the polishing wheel to rotate to a position opposite to the position where the pressure roller needs to be polished through a power drive assembly. At this time, some parts in the polishing assembly are controlled to work so that the support limit of the polishing wheel is released. At this time, the polishing wheel moves radially along the pressure roller under the action of its own gravity. At this time, when the polishing wheel is above the horizontal position of the pressure roller, the polishing wheel moves by its own gravity and then separates from the pressure roller. When the polishing wheel is below the horizontal position of the pressure roller, the power drive assembly drives the polishing wheel to rotate to a position opposite to the position where the pressure roller needs to be polished. Some parts in the power drive assembly drive the polishing wheel to move along the radial position of the pressure roller, so that the polishing wheel moves toward the direction of the pressure roller. When the polishing wheel is in different positions, the polishing wheel is driven to move in different ways, thereby improving the polishing efficiency.

[0018] 2. The present invention controls the first electromagnet to be energized and magnetized. Under the action of magnetic attraction, the first rack moves and drives the driving gear ring to rotate, and the first elastic member is stretched. At this time, the first threaded rod rotates and drives the polishing wheel to move downward along the first guide rod, so that the polishing wheel fits the roller surface of the pressure roller, and then the third motor is driven to drive the connecting disk to rotate. The polishing wheel rotates synchronously to continuously polish and repair the roller surface of the pressure roller. The polishing wheel falls directly onto the pressure roller under its own gravity, which will generate a certain impact force on the pressure roller. Controlling the polishing wheel to fit the roller surface of the pressure roller in a short distance reduces the damage of the polishing wheel to the pressure roller.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For specific embodiment 1, please refer to Figure 1-12 The present invention is a roller surface polishing device, comprising an annular frame 1, a polishing assembly 2, a power drive assembly 3 and a clamping assembly 4. The annular frame 1 is mounted on an external frame, an annular groove 101 is provided on one side of the annular frame 1, and the polishing assembly 2 is mounted on one side of the annular groove 101. The polishing assembly 2 comprises a polishing wheel 201 (such as Figure 3As shown, the arrow range is the polishing operation range of the polishing wheel 201), the polishing wheel 201 is used to grind the roller surface after being damaged, the power drive component 3 is installed on the side of the polishing component 2 close to the annular frame 1, the power drive component 3 includes a rotating frame 301, a first motor 302 is fixedly arranged on one side of the rotating frame 301, and the polishing component 2 is driven to rotate by the first motor 302, the clamping component 4 includes symmetrically arranged clamping plates 401, and the pressure roller 5 is clamped between the two clamping plates 401, and the other end of the pressure roller 5 is detachably installed inside the annular frame 1 (the pressure roller 5 is assembled by a pressure roller shell and bearings, etc., which is a prior art and will not be elaborated here).

[0037] Specifically, a connecting plate 102 is fixedly provided on the inner side of the annular frame 1, a limiting ring 103 is fixedly provided on one end of the connecting plate 102, the limiting ring 103 is slidably engaged with the pressure roller 5, an L-shaped supporting frame 104 is fixedly provided on the bottom of the annular frame 1, the inner side of the L-shaped supporting frame 104 is rotatably connected to the rotating frame 301, a second motor is installed on one side of the rotating frame 301, a positioning cavity 105 is fixedly provided on one side of the L-shaped supporting frame 104, a sliding groove is opened inside the positioning cavity 105, the second motor is installed inside the positioning cavity 105 and is slidably engaged with the sliding groove in an annular direction.

[0038] The operation process of this embodiment is as follows: insert one end of the pressure roller 5 into the limiting ring 103, and at the same time, use the clamping assembly 4 to fix the position of the pressure roller 5, such as Figure 1 As shown, in the initial state, the polishing assembly 2 is at the rightmost end position of the pressure roller 5, and the polishing assembly 2 is arranged vertically. When the polishing wheel 201 is above the horizontal position of the pressure roller 5, the power driving assembly 3 drives the polishing wheel 201 to rotate to the required grinding position on the pressure roller 5. At this time, some parts in the polishing assembly 2 are controlled to work so that the support limit of the polishing wheel 201 is released. At this time, the polishing wheel 201 moves radially along the pressure roller 5 under the action of its own gravity. After the polishing wheel 201 moves by its own gravity, it still maintains a certain distance from the pressure roller 5 (to prevent the pressure roller 5 from directly falling, impacting and crushing the pressure roller 5 and causing secondary damage). The polishing assembly 2 is controlled to work again so that the polishing wheel 201 is pressed against the roller surface of the pressure roller 5 to be repaired. The polishing wheel 201 is controlled to rotate (rotate) to polish the roller surface. During this process, the power drive assembly 3 is used to drive the polishing assembly 2 to move along the axial direction of the roller surface. When the polishing is completed, the power drive assembly 3 is used to drive the polishing assembly 2 back to the initial position. Then, the polishing assembly 2 is moved to another repairing surface. The polishing assembly 2 is controlled to rotate by some parts in the power drive assembly 3 so that the polishing assembly 2 polishes other damaged areas of the roller surface of the pressure roller 5.

[0039] When the polishing wheel 201 is below the horizontal position of the pressure roller 5, the power drive component 3 drives the polishing wheel 201 to rotate to the required grinding position of the pressure roller 5, and some parts in the power drive component 3 drive the polishing wheel 201 to move along the radial position of the pressure roller 5, so that the polishing wheel 201 moves toward the direction of the pressure roller 5. After the movement of the polishing wheel 201 is completed, it still maintains a certain distance from the pressure roller 5. At this time, some parts in the polishing component 2 are controlled to work again so that the polishing wheel 201 is pressed against the roller surface of the pressure roller 5 that needs to be repaired. At this time, the roller surface is polished and ground by controlling the rotation of the polishing wheel 201. In this process, the power drive component 3 is used to drive the polishing component 2 to move axially along the roller surface. When polishing is completed, the power drive component 3 is used to drive the polishing component 2 to return to the initial position, and then some parts in the power drive component 3 are used to control the rotation of the polishing component 2, so that the polishing component 2 polishes and grinds other damaged parts of the roller surface of the pressure roller 5.

[0045] The operation process of this embodiment is as follows: in the initial state, the first baffle 220 is in the first chamber 218, the second baffle 228 and the third baffle 229 are both in the third chamber 224, the polishing wheel 201 is at the end of the pressure roller 5 away from the clamping assembly 4, the power drive assembly 3 drives the polishing wheel 201 to rotate to the roller surface of the pressure roller 5 to be repaired, when the polishing wheel 201 is above the horizontal position of the pressure roller 5, the second electromagnet and the third electromagnet are controlled to be energized, and under the magnetic repulsion force, the first baffle 220 is in the first chamber 218, the second baffle 228 and the third baffle 229 are in the third chamber 224, the polishing wheel 201 is at the end of the pressure roller 5 away from the clamping assembly 4, the power drive assembly 3 drives the polishing wheel 201 to rotate to the roller surface of the pressure roller 5 to be repaired, and when the polishing wheel 201 is above the horizontal position of the pressure roller 5, the second electromagnet and the third electromagnet are controlled to be energized, and under the magnetic repulsion force, the first baffle 220 is in the first chamber 218, the second baffle 228 and the third baffle 229 are in the first chamber 224, the second baffle 229 is in the first chamber 224, the second baffle 220 ... The plate 220 moves toward the second chamber 219, at which time the second elastic member 221 is compressed. Under the action of the U-shaped rod 232, the second baffle plate 228 moves toward the inside of the fourth chamber 225. At the same time, the third baffle plate 229 moves toward the inside of the fourth chamber 225. At this time, both the third elastic member 230 and the fourth elastic member 231 are compressed. At this time, under the action of the gravity ball 214 and the polishing wheel 201, the first L-shaped rod 209 moves downward along the first chamber 218 (see the attached figure for details). Figure 8-12), the second limiting rod 222 moves downward along the third chamber 224. During this process, the second L-shaped rod 212, the first limiting rod 213, the third L-shaped rod 216, the second rack 217, the fourth L-shaped rod 226 and the third rack 227 move downward synchronously. When the bottom of the first L-shaped rod 209 fits with the bottom of the first chamber 218, the polishing wheel 201 moves above the roller surface and has a certain distance from the roller surface. Then the first electromagnet is energized and magnetized. At this time, under the action of magnetic attraction, the first rack 206 moves and drives the driving gear ring 205 to rotate, and the first elastic member 208 is stretched. At this time, the first threaded rod 203 rotates and drives the polishing wheel 201 to move downward along the first guide rod 204, so that the polishing wheel 201 fits with the roller surface of the pressure roller 5. At this time, the third motor 211 is driven to drive the connecting plate 202 to rotate, and the polishing wheel 201 rotates synchronously to continuously polish and repair the roller surface of the pressure roller 5. During the polishing process, the polishing wheel 20 is driven by the power drive component 3. 1 moves along the roller surface until the damage repaired here is completed. After the repair is completed, the third motor 211 is turned off and the first electromagnet is controlled to be powered off and demagnetized. At this time, under the action of the first elastic member 208, the first rack 206 moves in the opposite direction to drive the driving gear ring 205 to rotate in the opposite direction. The first threaded rod 203 rotates in the opposite direction to drive the polishing wheel 201 to move upward along the first guide rod 204, so that the polishing wheel 201 is away from the roller surface of the pressure roller 5. Then, the power drive component 3 is used to drive the polishing wheel 201 back to the initial position. At this time, the power drive component 3 is used to control the polishing wheel 201 to revolve along the pressure roller 5 again so that the polishing wheel 201 is at the roller surface position to be repaired at other positions of the pressure roller 5. At this time, the first electromagnet is controlled to be powered on again to magnetize so that the polishing wheel 201 is again attached to the roller surface and the roller surface is polished and repaired by the above-mentioned polishing method. When the polishing wheel 201 is above the pressure roller 5, the polishing wheel 201 can move radially by relying on its own gravity and the gravity of the gravity ball 214;

[0046] When the polishing wheel 201 rotates to the bottom of the pressure roller 5, the gravity ball 214 is above the pressure roller 5. Under the action of its own gravity, the polishing wheel 201 moves and drives the first L-shaped rod 209 to move along the first chamber 218 until the first L-shaped rod 209 fits with the inner bottom of the first chamber 218 (the inner bottom here is the relative position of the inner bottom of the first chamber 218 when the polishing wheel 201 is above the pressure roller 5). The polishing wheel 201 returns to the initial position of the first limit frame 215. At this time, the gravity ball 214 synchronously moves to the initial position of the second limit frame 223. At this time, the power drive component 3 drives the first L-shaped rod 209 to move along the first chamber 218. The dynamic gravity ball 214 continues to move along the second limit frame 223, and during this process the polishing wheel 201 moves toward the pressure roller 5. When the gravity ball 214 moves to the end position of the second limit frame 223, the polishing wheel 201 moves above the roller surface and has a certain distance from the roller surface. At this time, the first electromagnet is energized to magnetize. Under the action of magnetic attraction, the first rack 206 moves to drive the driving gear ring 205 to rotate, and the first elastic member 208 is stretched.

At this time, the power drive component 3 is used again to control the polishing wheel 201 to revolve along the pressure roller 5 so that the polishing wheel 201 is at the roller surface position to be repaired at other positions of the pressure roller 5. At this time, the first electromagnet is energized again to magnetize the polishing wheel 201 so that the polishing wheel 201 is in contact with the roller surface again and the roller surface is polished and repaired by the above-mentioned polishing method. When the polishing wheel 201 is below the pressure roller 5, the power drive component 3 is required to move the polishing wheel 201 toward the roller surface of the pressure roller 5.

[0052] The operation process of this embodiment is as follows: in the initial state, the driving gear 305 is meshed with the second rack 217 and the third rack 227, and the push plate 308 is at the rightmost end (see the attached Figure 5 As shown in the figure, the fifth elastic member is stretched. When the polishing wheel 201 is above the pressure roller 5, the second motor is controlled to drive the second threaded rod 307 to rotate. At this time, the push plate 308 moves to the left. At this time, under the action of the fifth elastic member, the driving gear 305 moves until the driving gear 305 is disengaged from the second rack 217 and the third rack 227. At this time, before the polishing wheel 201 moves toward the roller surface of the pressure roller 5, the first motor 302 is driven to drive the rotating frame 301 to rotate so that the transmission rod 303 rotates. The rotation of the rotating frame 301 drives the second threaded rod 307 to rotate, so that the rotating disk 304 rotates to drive the connecting rod 314 to rotate, and the driving gear 305 rotates synchronously. At this time, the first limit frame 215 The second limiting frame 223 revolves to make the polishing wheel 201 rotate, and the gravity ball 214 rotates at the same time.

Then, the polishing wheel 201 is continuously controlled to fit with the roller surface of the pressure roller 5. The pressure roller 5 can be polished by the self-rotation of the polishing wheel 201. In this process, the fourth motor 311 is controlled to rotate to drive the third threaded rod 312 to rotate, so that the positioning plate 309 moves along the third limiting plate 313. At this time, the positioning plate 309 drives the polishing assembly 2 to move along the roller surface of the pressure roller 5. When the polishing wheel 201 rotates to above the pressure roller 5, the polishing wheel 20 1 returns to the initial position of the first limiting frame 215, and the gravity ball 214 moves synchronously to the initial position of the second limiting frame 223. At this time, the second motor can be controlled to rotate in the opposite direction to drive the second threaded rod 307 to rotate in the opposite direction. At this time, the push plate 308 moves to the right, and the driving gear 305 moves to the right. At this time, the fifth elastic member is stretched until the driving gear 305 is meshed with the second rack 217 and the third rack 227 again. Then, the first motor 302 drives the rotating frame 301 to rotate so that the transmission rod 303 rotates. The rotating frame 301 rotates to drive the second threaded rod 307 to rotate, so that the rotating disk 304 rotates to drive the connecting rod 314 to rotate, and the driving gear 305 rotates synchronously. At this time, the first limiting frame 223 is rotated. The second limiting frame 223 of the positioning frame 215 revolves, causing the polishing wheel 201 to rotate, and the gravity ball 214 rotates at the same time. At this time, the position of the polishing wheel 201 is adjusted by the rotating frame 301.

At this time, the second rack 217 drives the third L-shaped rod 216 to move, and the first L-shaped rod 209 moves to drive the polishing wheel 201 to move toward the roller surface of the pressure roller 5. At this time, the polishing wheel 201 can be moved toward the pressure roller 5 by rotating the driving gear 305, and then the polishing wheel 201 is continuously controlled to fit with the roller surface of the pressure roller 5, and the pressure roller 5 can be polished by the self-rotation of the polishing wheel 201.
