DETAILED DESCRIPTION

[0024] In this embodiment, Figure 1 and Fig.10 As shown, a motor 8 is fixedly connected to the middle of the upper end of the base 2, and the output end of the motor 8 is fixedly connected to the bracket 1.

[0025] Specifically, the mounting plate 7 is installed on the bottom of the conveyor by bolts, and the middle roller 3 is in contact with the bottom of the conveyor belt. The middle roller 3 is used to provide support for the bottom of the conveyor belt. The side rollers 4 are on both sides of the conveyor belt, and when the conveyor belt is not deviating, the side rollers 4 are not in contact with the conveyor belt. Then two position sensors are arranged on both sides of the conveyor belt. The position sensor is an existing technology for detecting whether the conveyor belt is deviating. It will not be described in detail here. The position sensor is flush with the conveyor belt. The position sensor controls the motor 8 through the controller to work. When the position sensor detects that the conveyor belt is deviating, the motor 8 drives the bracket 1 to rotate at an appropriate angle, so that the side rollers 4 are in contact with the conveyor belt and correct it, thereby realizing automatic deviation correction of the conveyor belt and ensuring the normal operation of the conveyor belt.

[0026] In this embodiment, Figure 2-Figure 9 As shown, one end of the support plate 10 is threadedly connected to a threaded rod 14, both ends of the threaded rod 14 are rotatably set on the bracket 1, and both sides of the upper end of the bracket 1 are fixedly connected to a motor 2 11, and the output end of the motor 2 11 is fixedly connected to one end of the threaded rod 14.

[0027] A plurality of displacement rods 22 are inserted and slidably connected to one side of the housing 15 , and a scraper 23 is fixedly connected to one end of the displacement rod 22 . Both sides of the scraper 23 are in contact with the partition 25 , and one side of the scraper 23 is flush with the surface of the side roller 4 .

[0028] One end of the displacement rod 22 is fixedly connected to the connecting ring 17, one side of the connecting ring 17 is threadedly connected to the threaded rod 21, one end of the threaded rod 21 is rotatably set on the shell 15, one side of the shell 15 is fixedly connected to the motor 3 20, and the output end of the motor 3 20 is fixedly connected to one end of the threaded rod 21.

[0029] A connecting rod 29 is rotatably provided on one side of the stopper 30 , and an adjusting ring 18 is rotatably provided on one end of the connecting rod 29 .

[0030] A cylinder 28 is fixedly connected to one side of the merging ring 9 , and a piston end of the cylinder 28 is fixedly connected to one side of the adjusting ring 18 .

[0031] An electric heating plate 26 is disposed in the inner cavity of the scraper 23 , and the scraper 23 is made of a heat-conducting material.

[0032] Specifically, when the existing deviation correction device is in use, when it is detected that the conveyor belt is deviating, the side roller 4 will rotate and contact with the conveyor belt, so as to correct the deviation of the conveyor belt. However, since the side roller 4 needs to contact with the conveyor belt when correcting the deviation of the conveyor belt, and the conveyor belt is in a running state, the side roller 4 will form friction with the conveyor belt. When the friction force is large, the wear degree of the side roller 4 and the conveyor belt will be aggravated, and their service life will be reduced. When the wear is serious, the side roller 4 or the conveyor belt needs to be replaced, which not only increases the maintenance cost but also affects the normal operation of the conveyor belt. Therefore, in order to solve the above-mentioned problem, when the present embodiment is in use, since the side roller 4 corrects the deviation of the conveyor belt, the side roller 4 always uses its fixed area to contact the conveyor belt. For the convenience of subsequent description, this fixed area is called the correction area. When the conveyor belt is not deviated, the end face of one side of the shell 15 is in contact with the end face of one side of the merging ring 9. The correction area of ​​the side roller 4 is covered by the shell 15 and is in the closed cavity formed by the shell 15 and the merging ring 9. The partition plate 25 is in contact with the surface of the side roller 4. When the conveyor belt deviates, the pump body 13 draws out the lubricating oil in the oil storage tank 5, and sprays it from the oil outlet 24 after passing through the hose 12 and the annular tube 16. The lubricating oil sprayed from each oil outlet 24 will only be in the corresponding lubricating oil flow channel, so that the flow range of the lubricating oil can be effectively controlled, so that the lubricating oil can be evenly distributed on the surface of the side roller 4, avoiding the lubricating oil on the surface of the side roller 4. The side roller 4 is unevenly distributed. At the same time, since the inner cavity of the scraper 23 is provided with an electric heating plate 26, the electric heating plate 26 is energized for heating, so that the temperature of the inner cavity of the shell 15 rises, and the lubricating oil is heated. The heating will reduce the viscosity of the lubricating oil, and the lubricating oil can be spread on the surface of the side roller 4 more quickly, which is helpful to form a more uniform and complete lubricating film on the surface of the side roller 4. After the lubricating film is quickly formed on the surface of the side roller 4, the motor 2 11 drives the threaded rod 14 to rotate, so that the support plate 10 slides on the bracket 1, so that the correction area of ​​the side roller 4 is exposed. At this time, the side roller 4 contacts the conveyor belt for correction, which will greatly reduce the friction between the side roller 4 and the conveyor belt, thereby reducing the wear degree of the side roller 4 and the conveyor belt, which is beneficial to increase the service life of the side roller 4 and the conveyor belt, and at the same time, reduces the maintenance cost and ensures the normal operation of the conveyor belt. Although the friction between the side roller 4 and the conveyor belt is reduced by the above method, in some cases, the conveyor belt will transport some materials with strong adhesion. When the side roller 4 contacts the conveyor belt, it is inevitable that some materials will adhere to the surface of the side roller 4, which will not only affect the subsequent formation of the lubricating film on the surface of the side roller 4, but also cause the materials adhered to the side roller 4 to fall onto the conveyor belt again and mix with other types of materials, thereby affecting the quality of the materials. Therefore, in order to solve this problem, after the side roller 4 completes a deviation correction work and resets, the shell 15 is driven to contact the merging ring 9 again, so that the deviation correction area of ​​the side roller 4 is covered again, and at the same time, the motor 3 20 is used to drive the threaded rod 21 to rotate, so that the connecting ring 17 drives multiple displacement rods 22 to move simultaneously, so that the scraper 23 forms friction with the surface of the side roller 4, and the surface of the side roller 4 is The adhered material is scraped off. At the same time, the electric heating plate 26 can also heat up the inner cavity of the shell 15. After the adhered material is heated, it is easier to detach from the surface of the side roller 4, and the scraped material will slide to the surface of the merging ring 9, and then the cylinder 28 is used to drive the adjustment ring 18 to move, so that the multiple connecting rods 29 rotate at the same time and drive the block 30 to move, so that the block 30 no longer covers the through hole 19, and the scraped material is discharged from the through hole 19. When the block 30 covers the through hole 19, it is conducive to the concentration of heat and the heating effect on the inner cavity of the shell 15 is good; thereby, the material adhered to the surface of the side roller 4 is removed, and the situation that the material adheres to the surface of the side roller 4 affects the subsequent lubricating film on the surface of the side roller 4 is avoided. At the same time, it is also avoided that the material adhered to the side roller 4 falls onto the conveyor belt again and mixes with other types of materials.

[0033] In this embodiment, Fig.11 As shown, a worm wheel 31 and a gear 27 are rotatably provided in the middle of the base 2, and a worm 32 is rotatably provided on one side of the base 2, and the worm 32 and the worm wheel 31 are meshed with each other.

[0034] The adjusting rod 6 is provided with a plurality of tooth blocks, and the gear 27 is meshed with the tooth blocks on the adjusting rod 6 .

[0035] Specifically, according to the span size of the belt conveyor frame, the rotating worm 32 drives the worm wheel 31 and the gear 27 to rotate, so that the adjustment rods 6 on both sides slide in different directions at the same time, and the spacing between the two mounting plates 7 is adjusted, thereby achieving adjustable installation and improving the scope of application.

[0036] Working principle: According to the span size of the belt conveyor frame, the worm 32 is rotated to drive the worm wheel 31 and the gear 27 to rotate, so that the adjustment rods 6 on both sides slide in different directions at the same time, and the spacing between the two mounting plates 7 is adjusted, thereby realizing adjustable installation and improving the scope of application. The mounting plate 7 is installed with the bottom of the conveyor through bolts, and the middle roller 3 is in contact with the bottom of the conveyor belt. The middle roller 3 is used to provide support for the bottom of the conveyor belt. The side rollers 4 are on both sides of the conveyor belt. When the conveyor belt does not deviate, the side rollers 4 do not contact the conveyor belt. Then two position sensors are set on both sides of the conveyor belt. The position sensors are existing sensors for conveyor belt. The technology for detecting whether the belt is deviating will not be described in detail here. The position sensor is aligned with the conveyor belt. The position sensor controls the motor 8 through the controller to work. When the position sensor detects that the conveyor belt is deviating, the motor 8 drives the bracket 1 to rotate at a suitable angle, so that the side roller 4 contacts the conveyor belt and corrects its deviation, thereby realizing automatic deviation correction of the conveyor belt and ensuring the normal operation of the conveyor belt. When the conveyor belt is not deviating, the end face of one side of the shell 15 fits with the end face of one side of the merging ring 9, and the correction area of ​​the side roller 4 is covered by the shell 15, which is in the closed cavity formed by the shell 15 and the merging ring 9, and the separation The scraper 25 is in contact with the surface of the side roller 4. When the conveyor belt deviates, the pump body 13 draws the lubricating oil in the oil storage tank 5, and sprays it out from the oil outlet 24 after passing through the hose 12 and the annular tube 16. The lubricating oil sprayed out from each oil outlet 24 will only be in the corresponding lubricating oil flow channel, so that the flow range of the lubricating oil can be effectively controlled, so that the lubricating oil can be evenly distributed on the surface of the side roller 4, avoiding the situation that the lubricating oil is unevenly distributed on the side roller 4. At the same time, since the inner cavity of the scraper 23 is provided with an electric heating plate 26, the electric heating plate 26 is electrically heated to heat the inner cavity of the shell 15, so that the lubricating oil can be heated, and the heating will reduce the lubricating oil. The viscosity of the lubricating oil allows the lubricating oil to spread faster on the surface of the side roller 4, which helps to form a more uniform and complete lubricating film on the surface of the side roller 4. After the lubricating film is quickly formed on the surface of the side roller 4, the motor 2 11 drives the threaded rod 14 to rotate, so that the support plate 10 slides on the bracket 1, so that the correction area of ​​the side roller 4 is exposed. At this time, the side roller 4 contacts the conveyor belt for correction, which will greatly reduce the friction between the side roller 4 and the conveyor belt, thereby reducing the wear degree of the side roller 4 and the conveyor belt, which is beneficial to prolonging the service life of the side roller 4 and the conveyor belt, and at the same time, reduces the maintenance cost and ensures the normal operation of the conveyor belt.Although the friction between the side roller 4 and the conveyor belt is reduced by the above method, in some cases, the conveyor belt will transport some materials with strong adhesion. When the side roller 4 contacts the conveyor belt, it is inevitable that some materials will adhere to the surface of the side roller 4, which will not only affect the subsequent formation of the lubricating film on the surface of the side roller 4, but also cause the materials adhered to the side roller 4 to fall onto the conveyor belt again and mix with other types of materials, thereby affecting the quality of the materials. Therefore, in order to solve this problem, after the side roller 4 completes a deviation correction work and resets, the shell 15 is driven to contact the merging ring 9 again, so that the deviation correction area of ​​the side roller 4 is covered again, and at the same time, the motor 3 20 is used to drive the threaded rod 21 to rotate, so that the connecting ring 17 drives multiple displacement rods 22 to move simultaneously, so that the scraper 23 forms friction with the surface of the side roller 4, and the surface of the side roller 4 is The adhered materials are scraped off. At the same time, the electric heating plate 26 can also heat up the inner cavity of the shell 15. After the adhered materials are heated, they are easier to detach from the surface of the side roller 4, and the scraped materials will slide to the surface of the merging ring 9. Then, the cylinder 28 is used to drive the adjustment ring 18 to move, so that the multiple connecting rods 29 rotate at the same time and drive the block 30 to move, so that the block 30 no longer covers the through hole 19, and the scraped materials are discharged from the through hole 19. When the block 30 covers the through hole 19, it is conducive to the concentration of heat, and the heating effect of the inner cavity of the shell 15 is good; thereby, the materials adhered to the surface of the side roller 4 are removed, and the situation that the materials adhere to the surface of the side roller 4 affect the subsequent formation of the lubricating film on the surface of the side roller 4 is avoided. At the same time, it is also avoided that the materials adhered to the side roller 4 fall onto the conveyor belt again and mix with other types of materials. ;
