Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a deviation corrector. Background Art

[0002] Belt conveyor is a commonly used material conveying equipment. The conveying part of the belt conveyor is mainly composed of a belt and a supporting roller that supports the belt. The material falls on the belt. As the belt moves, the supporting roller plays a bearing role on the belt and the material on the belt.

[0003] When the conveyor belt is too long or the material is unevenly distributed on the belt, it is easy to cause the belt to deviate in the axial direction of the supporting roller. The belt deviation will cause the side of the belt to contact the frame on which the supporting roller is installed, causing the belt to vibrate, making it easy for the material to overflow from the deviated belt and causing material waste and dust.

[0004] At present, two inclined rollers are mainly set on both sides of the supporting roller, and the two inclined rollers are used to support and lift up the two sides of the belt, so that the belt is in a groove shape to prevent the belt from deviation. When the belt is transporting materials, the materials can always be in the middle of the belt to avoid material spillage. However, when the transported material blocks are large, the large pieces of material are easy to get stuck in the concave belt, causing extrusion damage to the supported parts on both sides of the belt, and even the sharp points on the surface of the material can pierce the belt. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a deviation corrector, comprising: a base 1, and also comprising: two special-shaped plates 2 installed on the top outer wall of the base 1, two supporting rollers 3 are rotatably installed on the outer walls of the two special-shaped plates 2 on opposite sides, and support shafts 4 are rotatably installed at both ends of the top outer wall of the base 1, telescopic boxes 5 are rotatably installed on the two support shafts 4, and inclined rollers 6 are installed on the two telescopic boxes 5, a long groove 7 is opened on the top outer wall of the base 1, and a two-way threaded rod 8 is inserted into the outer wall of one side of the base 1 through a bearing, a motor 10 and a controller 11 are installed on the outer wall of one side of the base 1, and the output shaft of the motor 10 is connected to one end of the two-way threaded rod 8, support components 9 are screwed at both ends of the two-way threaded rod 8, and the tops of the two support components 9 are respectively connected to the bottoms of the two telescopic boxes 5, and pressure sensors 12 are installed in the two telescopic boxes 5.

[0020] It should be noted here that: the belt is arranged on two supporting rollers 3 and two inclined rollers 6 to form a groove shape, and the two inclined rollers 6 support and lift up the two sides of the belt, and also play a limiting role on the belt to prevent the belt from running off, so that when the belt is transporting materials, the materials can always be in the middle of the belt, and the belt runs smoothly to avoid the occurrence of material scattering and dust. When the belt is transporting materials, when the transported material blocks are large, the materials are easy to get stuck in the concave belt, which is easy to cause damage to the belt. At this time, the material will give the inclined roller 6 a large lateral pressure, and the inclined rollers 6 on both sides will be supported outward, so that the telescopic box 5 will shrink and deform. The contraction of the telescopic box 5 to a certain extent will squeeze the pressure sensor 12, and the pressure sensor 12 will transmit the pressure signal to the controller 11. The controller 11 controls the motor 10 to drive the bidirectional threaded rod 8 to rotate, adjust the inclination state of the two supporting assemblies 9, and then adjust the inclination state of the two telescopic boxes 5, and then adjust the inclination state of the two inclined rollers 6. The angle between the two inclined rollers 6 can be automatically expanded, which is convenient for carrying large pieces of materials and convenient for the belt to better transport large pieces of materials.

[0021] In a preferred embodiment, the telescopic box 5 includes a box body 501, a movable plate 502 slidably connected to the inner wall of the box body 501, springs 503 fixed to the two ends of the bottom inner wall of the box body 501, guide tubes 504 fixed to the two ends of the bottom inner wall of the box body 501, and guide rods 505 slidably connected to the inner walls of the two guide tubes 504, and the tops of the two guide rods 505 are connected to the bottom outer wall of the movable plate 502.

[0022] It should be noted that when the inclined roller 6 is subjected to pressure, the movable plate 502 will be pushed into the box body 501 . When the movable plate 502 is pushed to a certain distance, the movable plate 502 will press against the pressure sensor 12 .

[0023] In a preferred embodiment, the support assembly 9 includes a slider 901, a first rod 902 rotatably mounted on the top of the slider 901, a second rod 903 rotatably mounted on one end of the outer wall of the bottom plate of the telescopic box 5, and a support rod 904 rotatably connected to the first rod 902 and the second rod 903.

[0024] It should be noted here that: the bidirectional threaded rod 8 rotates so that the two sliders 901 can move relative to each other in the long groove 7 at the same time, thereby simultaneously pulling the bottom ends of the two support rods 904 to move, while changing the inclination state of the two support rods 904, thereby adjusting the inclination state of the two telescopic boxes 5.

[0025] In a preferred embodiment, an arc-shaped groove 13 is formed on the outer wall of one side of the two special-shaped plates 2 .

[0026] It should be noted here that: when the angle of the inclined roller 6 is adjusted, the bottom end thereof will not touch the special-shaped plate 2 .

[0027] In a preferred embodiment, the thread directions of the two ends of the bidirectional threaded rod 8 are opposite.

[0028] It should be noted here that only when the threads at both ends of the bidirectional threaded rod 8 are in opposite directions, the two sliders 901 can move relative to each other when the bidirectional threaded rod 8 rotates.

[0029] In a preferred embodiment, the motor 10 and the two pressure sensors 12 are connected to the controller 11 via signal lines.

[0030] It should be noted here that the controller 11 can control the motor 10 and the two pressure sensors 12 .

[0031] Working principle: The belt is set on two supporting rollers 3 and two inclined rollers 6 to form a groove. The two inclined rollers 6 support and lift the two sides of the belt, and also limit the belt to prevent the belt from running off. When the belt is transporting materials, the materials can always be in the middle of the belt, and the belt runs smoothly to avoid the occurrence of material scattering and dust.

[0032] When the belt is transporting materials, if the transported material blocks are large, the materials are easy to get stuck in the concave belt, which is easy to damage the belt. At this time, the materials will give a large lateral pressure to the inclined roller 6, pushing the inclined rollers 6 on both sides outward. When the inclined rollers 6 are under pressure, the telescopic box 5 will shrink and deform, that is, the inclined rollers 6 will push the movable plate 502 into the box body 501. When it is pushed to a certain distance, the movable plate 502 will press the pressure sensor 12, and the pressure sensor 12 will transmit the pressure signal to the controller 11;

[0033] The controller 11 controls the motor 10 to drive the bidirectional threaded rod 8 to rotate. The bidirectional threaded rod 8 rotates, so that the two sliders 901 can move relative to each other in the long groove 7 at the same time, and then pull the bottom ends of the two support rods 904 to move at the same time, and at the same time change the inclination state of the two support rods 904, and then adjust the inclination state of the two telescopic boxes 5, and then adjust the inclination state of the two inclined rollers 6, which can automatically expand the angle between the two inclined rollers 6, facilitate the carrying of large materials, avoid severe squeezing of the parts supported on both sides of the belt, and facilitate the belt to better transport large materials.
