Referring to fig. 1 and 2, the embodiment discloses a belt deviation preventing device, which includes a driven roller 100, a support 200, and a belt conveyor 600, wherein the support 200 is disposed below the belt conveyor 600 and semi-surrounds the belt conveyor 600, the driven roller 100 is mounted on the support 200 and supports the belt conveyor 600, and the belt deviation preventing device further includes a roller frame 400 and a vertical roller 300.

The roller frame 400 comprises at least one corner, a first end 410 and a second end 420, the first end 410 being flat and the second end 420 being provided with a threaded through hole 421.

The vertical roller 300 comprises a moving roller 310 and a connecting shaft 320, and the bottom of the connecting shaft 320 is provided with an external thread 321.

The movable roller 310 is fixedly installed on the second end portion 420 of the roller frame 400 through the external thread 321 at the bottom of the connecting shaft 320, so that the movable roller 310 is installed at both sides of the belt conveyor 600 in a splayed manner by inclining inward.

The belt deviation preventing device disclosed in the embodiment realizes that when the belt conveyor 600 deviates leftwards or rightwards in the transportation process, the driven roller 310 blocks by setting the movable roller 310 which inclines inwards to form a splayed shape on two sides of the belt conveyor 600, achieves the technical effect of preventing the belt conveyor 600 from deviating seriously to separate from the rotary deviation correcting device, and greatly improves the safety in operation and the stability in belt conveying.

In practical applications, the roller frame 400 may be fixed to the bracket 200 by welding, integral forming, or the like. Of course, in some preferred embodiments, referring to fig. 1 and 2, the first end portion 410 is provided with a platform having a through hole 411 at both sides thereof, and the roller frame 400 is fixed to the bracket 200 by a screw passing through the through hole 411. Through the arrangement mode, the support 200 can be independently assembled and disassembled, different supports 200 can be conveniently replaced to meet actual requirements, and the practicability of the belt deviation preventing device is greatly improved.

In certain preferred embodiments, referring to fig. 1 and 2, the roller housing 400 includes a first corner 430 and a second corner 440, the first corner 430 being angled at 120 ° to 150 ° and the second corner 440 being angled at 90 °.

The angle of the first corner 430 is set to be 120-150 degrees, the compactness between the roller frame 400 and other mechanisms is improved to the maximum degree while the installation of the roller frame 400 is realized, and the occupied area of the belt deviation preventing device is favorably reduced.

The second rotation angle 440 is 90 degrees, the orientation of the movable roller 310 is affected by the second rotation angle 440 degrees, and the second rotation angle 440 degrees is set to be 90 degrees, so that the radial rotation direction of the movable roller 310 is consistent with the transmission direction of the belt conveyor belt 600, and the friction resistance of the belt conveyor belt 600 is reduced.

Of course, in some alternative embodiments, the roller frame 400 may be configured to have only one corner, such as the roller frame 400 having an "L" shape, which is simpler and more convenient to manufacture, but has a relatively reduced degree of compactness between the mechanisms, compared to the roller frame 400 having two corners in the above-described embodiments.

Further, the roller frame 400 can also be set to be an arc-shaped corner, if the roller frame 400 is in an S shape, the S-shaped roller frame 400 can adapt to avoidance positions in different application scenes, meanwhile, the arc-shaped corner is smooth and has no edge angle, injury can be reduced when accidental collision occurs with a human body, safety of the belt deviation prevention device is improved, and the structure is high in processing difficulty and high in manufacturing cost.

In addition, in practical applications, the shape of the movable roller 310 may be a rectangular parallelepiped, a curved stripe-shaped solid, or the like. Of course, in certain preferred embodiments, the movable roller 310 is cylindrical or funnel shaped.

The movable roller 310 is arranged to be a cylinder, referring to fig. 1 and fig. 2, the cylinder is regular in shape and simple to process, the belt conveyor 600 deviates and is tangent to the cylindrical surface of the movable roller 310, compared with other shapes, the cylindrical surface reduces the resistance of the belt conveyor 600 to the greatest extent, and the movable roller 310 is ensured to block the deviation of the belt conveyor 600 and simultaneously does not influence the movement of the belt conveyor 600.

Wherein the movable roller 310 is configured in a funnel shape, referring to fig. 3, the funnel shape is more complicated to process, but has lighter weight and less material consumption compared with a cylinder. In addition, the funnel-shaped movable roller 310 can further limit the off-tracking belt conveyor 600 at the middle position of the funnel shape, which is beneficial to improving the blocking effect of the movable roller 310.

In addition, in practical applications, the movable roller 310 may be made of wood, plastic, or the like. In some preferred embodiments, the movable roller 310 is made of a metal material, because the movable roller 310 can rub against the belt conveyor 600 when blocking the belt conveyor and generate heat due to friction, compared with wood and plastic, the metal material has good wear resistance, long service life and small influence of temperature, and the reliability and durability of the whole belt deviation prevention device are greatly enhanced by adopting the metal material.

Referring to fig. 2, the movable roller 310 is connected to the roller frame 400 through the external thread 321 of the connecting shaft 320, and is conveniently assembled and disassembled in a threaded connection manner, so that a user is allowed to replace different vertical rollers 300 to realize different functions or replace damaged vertical rollers 300, and the overall practicability of the belt deviation prevention device is improved.

The threaded connection allows the user to adjust the orientation of the movable roller 310 according to the deviation degree of the belt conveyor 600, and only the screwing depth between the external thread 321 on the connecting shaft 320 and the threaded through hole 421 of the second end 420 of the roller frame 400 needs to be changed.

In practical application, a threaded connection mode is adopted, the connecting shaft 320 rotates along a threaded path due to mechanical vibration, so that the position of the movable roller 310 is uncertain, and in order to ensure that the movable roller 310 can block the deviation of the belt conveyor 600, the rotation of the connecting shaft 320 needs to be limited, so that the position of the movable roller 310 is fixed.

Therefore, the device for preventing the belt from deviating further comprises a locking device, and the locking device is arranged on the connecting shaft 320. The movable roller 310 is connected with the roller frame 400 through the external thread 321 at the bottom of the connecting shaft 320, and when the connecting shaft 320 rotates due to mechanical vibration, the locking device can provide resistance to prevent the connecting shaft 320 from rotating, so that the orientation of the movable roller 310 on the belt deviation prevention device is fixed.

In certain preferred embodiments, referring to fig. 2, the locking device comprises a lock washer 510 and a lock nut 520, wherein the lock washer 510 and the lock nut 520 are both disposed on the external thread 321. The lock washer 510 and the lock nut 520 are sleeved on the connecting shaft 320 and located between the movable roller 310 and the second end 420, and the lock nut 520 is located on the lock washer 510.

The mode has good fastening effect, is not easy to loosen parts influenced by vibration, and has enough safety.

The lock nut 520 may limit the rotation of the connection shaft 320, and the lock washer 510 is added to prevent the lock nut 520 from loosening.

In some alternative embodiments, referring to fig. 4, the connecting shaft 320 is provided with a positioning hole 322, the locking device is a bolt 530, and the bolt 530 passes through the positioning hole 322 to limit the rotation of the connecting shaft 320.

In the above optional embodiment, the rotation of the connecting shaft 320 is limited by the bolt 530, so that the processing and installation are simpler, the material consumption is less, and the cost is lower, but the positioning hole 322 needs to be formed in the connecting shaft 320, the orientation of the movable roller 310 is affected by the positioning hole 322, and is determined by the processing result of the positioning hole 322, and each independent positioning hole 322 corresponds to a specific orientation of the movable roller 310.

In some alternative embodiments, referring to fig. 5 and 6, the locking device may also be a C-clamp 540, the C-clamp 540 including a securing structure 541 at both ends, a C-handle 542.

The fixing structure 541 may be a clip, a buckle, or the like having a function of fixing the connecting shaft 320.

When the roller frame is used, the C-shaped handle 542 is matched with the roller frame 400, the fastening nuts with half-opened two ends are aligned to and matched with the external threads 321 on the connecting shaft 320, then the C-shaped clamp 540 is inserted into the connecting shaft 320, the connecting shaft 320 can be fixed, the direction of the movable roller 310 is fixed, and only the C-shaped clamp 540 needs to be pulled out during unloading. The C-shaped clamp 540 is more suitable for the condition that the effective length of the external thread 321 of the connecting shaft 320 far exceeds the depth of the threaded through hole 421 of the second end 420 of the roller frame 400, and the connecting shaft 320 is locked up and down at the same time, so that the reliability of the locking device is improved, and the assembly and disassembly are more convenient.

In some possible embodiments, in the case that the effective length of the external thread 321 of the connecting shaft 320 far exceeds the depth of the threaded through hole 421 of the second end 420 of the roller frame 400, the same lock washer 510 and the same lock nut 520 can be respectively installed at the upper end and the lower end of the connecting shaft 320, and the simultaneous locking of the upper end and the lower end of the connecting shaft 320 can also play a role in fixing the connecting shaft 320, which is not inferior to the reliability of the C-shaped clamp 540, but the number of components to be installed is relatively large, and the installation is more complicated.

The above-mentioned embodiment of the present invention is not limited to the corner structure of the roller frame 400, and all the roller frame 400 structures with corners for connecting the bracket 200 and the vertical roller 300 are within the scope of the present invention.
