Description

Technical Field

[0001] The utility model belongs to the technical field of belt deviation correction, and in particular relates to a baffle device for preventing a large belt from returning to its original position after deviation correction. Background Art

[0002] The belt on the transmission belt is prone to deviation during the transmission process. The harm of belt deviation is that the material is spilled, the belt conveyor cannot run at full load, and the belt is worn. In severe cases, it may cause accidents such as belt tearing and emergency stop. The existing methods for belt deviation cannot be reliable and effective in the long term, and can not cure it without any damage to the tape.

[0003] At present, there are two ways to correct the deviation: one is the shift pulley and the other is the cylinder. However, the shift pulley only prevents the belt from going beyond the specified position, but cannot correct the deviation and return it. Although the use of the cylinder can solve the problem of the belt correction and return, the impact force on the correction shaft is too strong and not gentle, which will cause short-term damage to the correction shaft seat. This will cause instability in the operation of the belt, and there are certain restrictions on the use of both. Utility Model Content

[0004] The utility model aims to provide a baffle device for preventing a large belt from returning to its original position after deviation correction, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A baffle device for preventing a large belt from returning to its original position after deviation correction, comprising:

[0007] A conveying mechanism, wherein sliding frames are arranged on both sides of the conveying mechanism;

[0008] A deflection correction mechanism is arranged inside the two sliding frames, the deflection correction mechanism comprises a sliding block slidably installed inside the sliding frame, a rotating cavity is opened inside the two sliding blocks, a rotating block is rotatably installed inside the rotating cavity, and a deflection correction shaft is rotatably installed between the two rotating blocks;

[0009] An airbag driving mechanism is arranged inside the sliding frame;

[0010] The limiting mechanism is arranged on one side opposite to the two sliding blocks.

[0011] Preferably, the airbag driving mechanism includes elastic airbags arranged on the top and bottom of the sliding block.

[0012] Preferably, opposite sides of the two elastic airbags are fixedly connected to the top and bottom of the sliding block respectively.

[0013] Preferably, the sides of the two elastic airbags that are away from each other are both fixedly connected to the inner wall of the sliding frame.

[0014] Preferably, the limiting mechanism includes a baffle fixedly mounted on one side of the sliding block.

[0015] Preferably, a monitoring mechanism is fixedly mounted on the top of the baffle.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) Through the setting of the correction mechanism and the limit mechanism, the correction axis can be automatically controlled to move when the belt is corrected, and the baffle can also effectively limit the degree of deviation of the belt. At the same time, the position of the correction axis can be controlled to achieve control of the tightness of the belt.

[0018] (2) By setting up the airbag driving mechanism, the movement of the sliding block is controlled by the expansion and contraction of the two airbags, and the sliding block then drives the correction shaft to move, so that the movement of the correction shaft is more gentle and the impact force on the correction shaft is reduced.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 3 As shown, a baffle device for preventing a large belt from returning to its original position after deviation correction comprises:

[0026] A conveying mechanism 1, with sliding frames 2 disposed on both sides of the conveying mechanism 1;

[0027] The deflection correction mechanism is arranged inside the two sliding frames 2, and the deflection correction mechanism includes a sliding block 3 slidably installed inside the sliding frame 2, and a rotating cavity 4 is opened inside the two sliding blocks 3. A rotating block 5 is rotatably installed inside the rotating cavity 4, and a deflection correction shaft 6 is rotatably installed between the two rotating blocks 5;

[0028] The airbag driving mechanism is arranged inside the sliding frame 2;

[0029] The limiting mechanism is arranged on one side opposite to the two sliding blocks 3 .

[0030] Depend on Figure 1 and Figure 3 It can be seen that the airbag driving mechanism includes elastic airbags 7 arranged at the top and bottom of the sliding block 3, the opposite sides of the two elastic airbags 7 are fixedly connected to the top and bottom of the sliding block 3 respectively, the sides of the two elastic airbags 7 away from each other are fixedly connected to the inner wall of the sliding frame 2, and the two elastic airbags 7 are connected to the external air pump.

[0031] As can be seen from the above, when the conveying mechanism 1 needs to be corrected during use, the external air pump is started. When the transmission belt inside the conveying mechanism 1 is corrected to one side, the elastic airbag 7 located at the bottom of the other side is inflated, and the elastic airbag 7 located at the top is deflated, thereby driving the sliding block 3 located on the other side to move upward, so that the deviated transmission belt can be moved to its original position. After the correction is completed, the two elastic airbags 7 are restored to their original state, and the correction of the transmission belt can be completed. At the same time, the two sliding blocks 3 can be moved simultaneously through the airbag driving mechanism to control the tightness of the transmission belt.

[0032] Embodiment 2:

[0033] refer to Figure 2 As shown, the limiting mechanism includes a baffle 8 fixedly mounted on one side of the sliding block 3, and a monitoring mechanism 9 is fixedly mounted on the top of the baffle 8. The monitoring mechanism 9 is an infrared distance sensor that can detect the distance between the transmission belt below and the baffle 8.

[0034] As can be seen from the above, when the infrared distance sensor detects contact between the transmission belt and the baffle 8, the deviation correction mechanism will be activated to correct the deviation of the transmission belt, and the baffle 8 can limit the degree of deviation correction of the transmission belt.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
