Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor deviation adjustment, in particular to an automatic spiral tensioning deviation adjustment machine tail device. Background Art

[0002] Belt conveyor is a kind of transfer equipment for conveying materials. The materials are transported through the conveyor belt on the belt conveyor. Belt conveyor is widely used in industry because it can not only transport materials over long distances, but also has high stability and can transport materials across heights. Therefore, in manufacturing enterprises, belt conveyors are widely used.

[0003] The main structure of the belt conveyor includes a frame, rollers supported at the bottom of the belt installed on the frame, and a tail installed at the rear of the frame, on which the rubber rollers for the transmission belt are installed. During operation, the rubber rollers at the head and tail of the machine rotate to realize the transmission of the belt. The continuous transmission of the belt realizes the transportation of materials from the tail to the head.

[0004] During the operation of the belt conveyor, the belt of the belt conveyor is prone to displacement, especially as the belt conveyor is used for a longer period of time, and the various components on the belt conveyor become loose, including belt aging and belt loosening during transmission, which reduces the stability during operation. Specifically, during the transmission process of the belt conveyor, once the belt becomes loose, it is easy to cause the belt to shift.

[0005] At present, the more common way to adjust the deviated belt is to adjust the tail of the belt conveyor, specifically by adjusting the rubber roller on the tail to adjust the loose tail from the deviated position to the initial position. After adjusting to the initial position, the rubber roller not only tightens the belt, but also continues to keep the belt transmitting on the correct trajectory. At present, the more common adjustment method is to use the adjustment screw on the tail. However, as the belt conveyor ages, the small-range adjustment at the beginning leads to the subsequent large-range adjustment. As a result, the adjustment screw is not only laborious to adjust gradually, but also often poorly adjusted, especially when both sides of the belt conveyor are deviated. If both sides cannot be adjusted at the same time, it is often difficult to adjust to the best initial state position. Utility Model Content

The adjustment tensioning screw is randomly pulled out for replacement (after repeated adjustment, the adjustment tensioning screw will deform more and the adjustment accuracy will decrease over time, so it is necessary to replace it). This method can achieve a more flexible replacement and greatly reduce the difficulty of replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figure 1-6 As shown, an automatic spiral tensioning and deflection-adjusting tail device includes a pulling mechanism installed on a belt conveyor (on a frame), specifically, a pulling mechanism 2 is installed on both sides of the belt conveyor frame, so that the tail can be adjusted from both sides through the pulling mechanisms 2 on both sides.

[0043] The specific structure of the pulling mechanism 2 is:

[0044] The pulling mechanism 2 includes a motor 21 (the motor 21 is a horizontal motor 21, and according to the existing method of fixing the motor 21, the motor 21 is fixedly installed on the frame of the belt conveyor through a motor 21 frame), and the output shaft of the motor 21 is transmission-connected with a screw tensioning assembly.

[0045] Specifically, the screw tensioning assembly includes a sprocket 24 that is transmission-connected to the motor 21 (specifically, the output shaft of the motor 21 is fixedly assembled and connected with a driving sprocket, and according to the existing chain transmission method, the driving sprocket and the sprocket 24 are transmission-connected through a chain 22). According to the existing method, a cover body 3 covering the sprocket 24 and the driving sprocket is installed on the frame.

[0046] The sprocket 24 is detachably assembled with the connecting column 26 through the first connecting member (specifically: the first connecting member includes a first connecting flange 241, one side of the first connecting flange 241 is fixedly connected to the sprocket 24 through a connecting shaft, and the existing rotation connection method is installed: the connecting shaft is rotatably connected to the frame of the belt conveyor, and the bearing is installed on the frame according to the existing method), and the screw tensioning assembly also includes a deviation adjustment tensioning screw 23 threadedly connected to the tail of the belt conveyor. During the rotation process, the depth of the deviation adjustment tensioning screw 23 threadedly connected to the tail changes, and the sprocket 24 remains in a horizontal position.

[0047] Specifically, the deflection adjustment tightening screw 23 is detachably assembled with a connecting sleeve 25 connected to the sleeve connecting column 26 through a second connecting member. The second connecting member is a second connecting flange 231, the deflection adjustment tightening screw 23 is fixedly connected to one side of the second connecting flange 231, and the connecting sleeve 25 is fixed to the other side of the second connecting flange 231.

[0048] At the same time, in order to facilitate the replacement of the deviation-adjusting tensioning screw 23 during the working process, the connecting column 26 and the connecting sleeve 25 are locked by a plurality of elastic locking structures.

[0049] Specifically, the elastic locking structure includes an elastic locking protrusion 261 assembled and connected to the connecting column 26 , and the elastic locking protrusion 261 is pressed, and the elastic locking protrusion 261 elastically rises and falls relative to the connecting column 26 .

[0050] The elastic locking protrusion 261 has a shape as follows: the elastic locking protrusion 261 includes a cylindrical portion slidably connected to the connecting column 26, and the cylindrical portion is integrally formed with a curved head. It is connected to the connecting column 26 via a spring, specifically: the connecting column 26 is provided with a plurality of spring grooves slidably connected to the elastic locking protrusion 261, and the elastic locking protrusion 261 is fixedly connected to a spring 2611, and the spring 2611 is fixedly connected to the bottom of the spring groove.

[0051] Correspondingly, the connecting sleeve 25 is provided with a plurality of locking holes adapted to the elastic locking protrusions 261 . When the connecting column 26 is plugged into the connecting sleeve 25 , the elastic locking protrusions 261 are locked in the locking holes.

[0052] During operation, the elastic locking protrusion 261 is pressed downward. At this time, the spring 2611 is compressed until the elastic locking protrusion 261 is disengaged from the locking hole position, and the deviation adjustment tensioning screw 23 is randomly pulled out for replacement (after the deviation adjustment tensioning screw 23 is repeatedly adjusted, the deformation of the deviation adjustment tensioning screw 23 increases with time, and the adjustment accuracy decreases, so it is replaced).

[0053] During assembly, the connecting sleeve 25 is pushed into the connecting column 26, and the connecting sleeve 25 is pressed against the curved head of the elastic locking protrusion 261 until the elastic locking protrusion 261 is again locked into the locking hole. In this way, replacement can be achieved in a more flexible manner, and the difficulty of replacement is greatly reduced.

[0054] Example 2

[0055] like Figure 1-6 As shown, based on the structure of embodiment 1, this embodiment, in accordance with the conventional method, in order to obtain the pressure values ​​on both sides of the belt on the belt conveyor, and then accurately determine the direction in which the belt is deflected, especially when the degree of deflection is not high, can be accurately known through the pressure sensor 1. Specifically, when the belt deflects to one side, the pressure value of the side pressure sensor 1 becomes larger. Therefore, a side pressure sensor 1 corresponding to the motor 21 on the side is installed on both sides of the frame.

[0056] At the same time, the pressure sensor 1 is electrically connected to the motor 21 at the position of the side in accordance with the conventional existing method. The specific method is the conventional method disclosed in the prior art. When the pressure value of the pressure sensor exceeds the threshold, the pressure sensor 1 feeds back the pressure signal to the motor 21 at the side, and the motor 21 at the side works and rotates in the above manner, and rotates the deviation adjustment tightening screw 23. The deviation adjustment tightening screw 23 pulls the tail of the machine through the thread driving force, and then adjusts the position of the tail of the machine to the initial state until the pressure value of the pressure sensor is reduced to below the threshold, and the motor 21 stops working. Similarly, the pressure sensor on the other side cooperates with the motor 21 on the other side to adjust the position of the tail of the machine from the other side.

[0057] By realizing automatic adjustment in the above manner, the adjustment flexibility and efficiency are greatly increased.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
