Description

Technical Field

[0001] The utility model belongs to the technical field of transmission protection equipment, in particular to a belt conveyor belt pressing roller. Background Art

[0002] The running length of the conveyor belt of the belt conveyor to the underground receiving hopper is close to ten meters. Generally, in order to ensure the stability of screening and transmission, the angle of the belt is relatively large. At the turning point where the belt changes direction to run upward, the upper part of the belt needs to be pressed by the belt pressure roller, otherwise the upper part of the belt will run in the air. The belt pressure roller is a belt guide device that changes the belt from parallel operation to slope operation. The change of direction of the belt operation produces a large friction force on the rubber layer of the belt pressure roller.

[0003] The prior art discloses a belt conveyor belt pressure roller (CN205739111U), which belongs to the field of transmission equipment accessories. The purpose of the utility model is to improve the conveyor belt support roller to provide a belt conveyor belt pressure roller that is easy to replace and reduces costs. The bearing seat of the utility model is installed on the frame, and the two ends of the rotating shaft are inserted into the bearing inner bush in the bearing seat. A fixed hoop, a pulley and a movable hoop are sequentially mounted on the rotating shaft. The pulley and the movable hoop are fixed to the fixed hoop by bolts, and the diameter of the pulley is larger than the diameter of the fixed hoop and the movable hoop; the movable hoop and the pulley are both spliced ​​by two pieces, one of which has a circular hole in the center that matches the rotating shaft, and the other is a square roller key hole, the roller key is placed in the roller key hole, and the roller key is stuck on the rotating shaft.

[0004] After searching, it was found that the device uses a pulley to guide and press the belt during operation, and the use of the pulley cannot adapt to the slope or angle of the belt, resulting in the phenomenon that the belt is away from the pulley, which causes the belt to be unable to be guided by the pulley and cannot be effectively pressed, which easily causes the belt to deviate from the track, affecting the use effect of the belt transmission and screening; furthermore, the pulley needs to be replaced due to wear after long-term use, and the pulley specifications cannot press the belt and also need to be replaced, which results in the belt conveyor being unable to be regulated during the replacement process due to lack of belt pressing measures, thereby affecting its use. The affected use of the belt conveyor is likely to affect the economic benefits, and the lack of regularization measures for the belt conveyor is likely to cause danger.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0031] The working principle is as follows: the bearing seat 10 is installed on the frame, and the two ends of the rotating shaft 12 are respectively inserted into the bearing inner bushes in the bearing seat 10, and the belt pressing roller 11 is fixed on the curved surface of the rotating shaft 12, so as to reduce the replacement of belt pressing rollers 11 of different specifications. By setting a regularization component, the regularization component is used to assist the belt pressing roller 11 to regularize the belt, and the handle threaded rod 20 is turned to push the regularization plates 16 on both sides to squeeze and regularize the belt. The addition of the regularization component prevents the belt pressing roller 11 from being unable to regularize the belt when replacing, thereby avoiding affecting the belt conveyor, thereby avoiding affecting the economic benefits, and thereby avoiding the danger caused by the deviation of the belt; by setting a belt pressing adaptation structure, the belt pressing block 21 is used to adapt to the slope of the belt, and the support and protection of the belt pressing block 21 by the block 14 prevents it from detaching.

[0032] like Figure 1 As shown, two regular components are symmetrically arranged, and the two regular components are respectively located at the two ends of the rotating shaft 12. The belt pressing roller 11 is fixedly arranged between the two regular components. A through hole is opened inside the belt pressing roller 11, and the belt pressing roller 11 is fixedly connected to the rotating shaft 12 through the through hole; Figure 1 , Figure 2 and Figure 4 As shown, the belt pressing roller 11 is provided with a plurality of fan-shaped adapting grooves 13, and the stopper 14 and the belt pressing block 21 are both provided with a plurality of stoppers 14.

[0033] The specific implementation is as follows: when the belt press roller 11 rotates, the belt press block 21 will contact the surface of the belt or the material above the belt, and the material or the belt will squeeze the belt press block 21. With the cooperation of the resistance spring 22 and the support of the resistance block 14, the belt press block 21 will be squeezed into the adaptation groove 13. At this time, no matter what the height of the belt press roller 11 is, the belt press block 21 will be squeezed inward when it contacts the surface of the belt or the material, thereby achieving the purpose of adapting to the slope of the belt.

[0035] The specific implementation is as follows: by rotating the handle threaded rod 20 to control the structuring plate 16 to approach the belt pressing roller 11, with the cooperation of the buffer spring 17 and the clamping plate 18, the structuring plate 16 can slide on the rotating shaft 12 and reach the upper sides of the belt. At this time, the bottom of the structuring plate 16 is able to contact the belt, thereby temporarily structuring the belt and guiding the belt. When the belt pressing adaptation structure is running, the rotating shaft 12 can be rotated by means of the rotating connection relationship between the movable ring 23 and the structuring plate 16, thereby reducing the wear on the surface of the rotating shaft 12 and the circular hole of the structuring plate 16.
