Description

Automatic correction device

technical field

The utility model relates to an auxiliary device in the material conveying process, in particular to an automatic deviation correcting device.

Background technique

With the continuous and rapid development of the national economy, belt conveyors have become the most important equipment in material conveying systems in all walks of life. The deviation of the conveyor belt (also known as the belt) is one of the most common faults of the belt conveyor. The main factors of common conveyor belt deviation are: roller manufacturing error and installation deviation, rack manufacturing error and installation deviation, conveyor belt manufacturing and joint quality resulting in geometric dimension (not straight, uneven thickness) error, roller Manufacturing errors and installation deviations, etc. There are many factors that cause the conveyor belt to deviate, but in the final analysis it is caused by the unbalanced force on the conveyor belt during operation and the presence of a lateral force perpendicular to the direction of conveyor belt movement.

In order to deal with the problem of conveyor belt deviation, the deviation correction methods used in the prior art mainly include manual adjustment and mechatronics adjustment. The cost of the adjustment method is relatively high.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the specific implementation manners of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model , not all embodiments, nor limitation of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

Fig. 1 is a schematic structural diagram of an automatic deviation correction device provided by Embodiment 1 of the present invention. As shown in Figure 1, the device includes a roller 1, a roller 2, a roller 3, and a conveyor belt 4 arranged on each roller, and the roller 1, the roller 2, and the roller 3 are parallel to each other. In this embodiment, the roller 1 , the roller 2 and the roller 3 have the same structure, and the structure of each roller will be described below taking the roller 1 as an example. Fig. 2 is a structural schematic diagram of the roller in the automatic deviation correction device provided by Embodiment 1 of the present utility model. As shown in Fig. 2, the roller 1 is composed of a cylinder 11, an end 12 and an end 13, and the end 12 and The ends 13 have the same shape and size and are arranged on both ends of the cylinder 11 in axisymmetric manner. Specifically, the end 12 is fixedly connected to the left end of the cylinder 11, and the end 13 is fixedly connected to the right end of the cylinder 11. The end 12 The cross-sectional diameter of the roller increases linearly from the center of the roller 1 to the left end of the roller 1, and the cross-sectional diameter of the end 13 increases linearly from the center of the roller 1 to the right end of the roller 1. It should be noted that the connection between the end 12 and the cylinder 11 The cross-sectional diameters are the same, and the cross-sectional diameters at the junction of the end portion 13 and the cylinder 11 are the same. In addition, it should be noted that in this embodiment, the length of the cylinder 11 is equal to the width of the conveyor belt 4 .

The working principle of Embodiment 1 will be described below. When the conveyor belt 4 deviates and passes the end 12 of the roller 1 due to the lateral component force it receives, due to the change of the diameter of the roller 1, along with the movement of the conveyor belt 4, The end 12 of the roller 1 will generate a reaction component force opposite to the side force component to the conveyor belt 4, so that the conveyor belt 4 returns to the center position.

Compared with Embodiment 1, only the structure of the rollers in the automatic deviation correction device provided by Embodiment 2 is different. Specifically, the device includes three rollers and a conveyor belt 4 arranged on each roller, of which the three rollers parallel to each other. In this embodiment, since the three rollers have the same structure, the roller 5 among the three rollers is selected for description. Fig. 2 is a structural schematic diagram of the roller in the automatic deviation correction device provided by Embodiment 2 of the present utility model. As shown in the figure, the roller 5 is composed of a cylinder 51, an end 52 and an end 53, and the end 52 and the end Part 53 has the same shape and size and is arranged on both ends of the cylinder 51 in axisymmetric manner. The end 52 is fixedly connected to the left end of the cylinder 51, and the end 53 is fixedly connected to the right end of the cylinder 51. Specifically, the roller 5 The end 52 is made up of a cylinder 521 and a nesting piece 522 nested on the cylinder 521, and the end 53 of the roller 5 is made up of a cylinder 531 and a nesting piece 532 nested on the cylinder 531. A nesting part 511 is nested on the cylinder 51 of 5, the cross-sectional diameters of the cylinder 51, the cylinder 521 and the cylinder 531 are the same, and the cross-sectional diameters of the nesting part 522 and the nesting part 532 are larger than the cross-section of the nesting part 511 diameter. It should be noted that this embodiment does not limit the number of nested parts. If there are multiple nested parts nested on the end 52, the diameter of these nested parts increases linearly from the center of the roller 5 to the left end of the roller 5. , if a plurality of nesting pieces are nested on the end portion 53, the diameters of these nesting pieces increase linearly from the center of the roller 5 to the right end of the roller 5, and the shape of the nesting pieces in this embodiment is a cylinder. In addition, it should be noted that in this embodiment, the length of the cylinder 51 is equal to the width of the conveyor belt 4 .

The working principle of the second embodiment is similar to that of the first embodiment. When the conveyor belt 4 deviates and passes through the nesting part 522 of the roller 5 due to the lateral component force it receives, due to the change of the diameter of the roller 5, along with the conveyor belt 4 The movement of the roller 5, the nesting part 522 of the roller 5 will generate a reaction component force opposite to the lateral component force on the conveyor belt 4, so that the conveyor belt 4 returns to the center position.

It can be seen from the above embodiments and the working principles of the embodiments that for the lateral component force received by the conveyor belt during operation, the automatic deviation correction device provided by the embodiment of the utility model can provide a reaction in the opposite direction to the lateral component force Force component, so as to realize the self-adaptive adjustment of the position of the conveyor belt, moreover, the structure of the embodiment of the utility model is simple, and the cost is low.
