Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

The utility model provides a center-adjusting bearing roller group under friction, includes two at least as shown in figure 1 center-adjusting bearing rollers under the friction that arrange in proper order along belt 5 direction of delivery, constitutes bearing roller group through setting up a plurality of center-adjusting bearing rollers down, can reduce the friction between single bearing roller and the belt 5, reduces the wearing and tearing of belt 5

As shown in fig. 1, each of the lower center-adjusting idlers includes a base 1, two roller mechanisms 2, a connecting rod 3, and two supporting mechanisms 4. The two roller mechanisms 2 and the two supporting mechanisms 3 are respectively and symmetrically arranged at two sides of the top of the base 1.

Each roller mechanism 2 includes a roller frame 21, a roller 22, a friction wheel 23, and a rotation shaft 24. The rotation shaft 24 is vertically disposed and rotatably coupled to the base 1 by a rotation bearing 25. The top of the rotating shaft 24 is hinged to one end of the bottom of the roller frame 21; the bottom of the supporting mechanism 4 is fixed to the base 1, and the top thereof abuts against the other end of the bottom of the roller frame 21. The rotating shaft 24 and the supporting mechanism 4 support both ends of the roller frame 21, respectively, so that the roller frame 21 is kept stable.

The roller 22 and the friction wheel 23 are rotatably mounted on the roller frame 21, and the friction wheel 23 is coaxially disposed at one end of the roller 22 away from the central axis of the base 1. The belt 5 rests on rollers 22 for conveying the material. One end of the roller 22, which is far away from the central axis of the base 1, is inclined upwards, so that the central axis of the belt 5 is concave downwards, the materials are gathered at the central axis of the belt 5, and the materials are prevented from scattering from two sides of the belt 5.

The diameter of one end of the friction wheel 23 close to the roller 22 is equal to that of the roller 22, and the diameter of the friction wheel 23 is gradually increased towards the direction far away from the roller 22. When the belt 5 deviates to one side, the friction wheel 23 on the side of the belt 5 contacts, the roller mechanism 2 on the side rotates forwards around the corresponding rotating shaft 24 by friction, and the friction wheel 23 rotates to reduce friction and reduce the abrasion of the belt 5. In addition, as shown in fig. 2, the swing rods 26 are disposed on the same side of the two rotating shafts 24, and two ends of the connecting rod 3 are respectively hinged to the two swing rods 26. Because the two rotating shafts 24 are connected through the connecting rod 3, when the roller mechanism 2 on one side rotates forwards, the roller mechanism 2 on the other side synchronously rotates backwards, so that the conveying direction of the belt 5 is adjusted, and the deviation rectifying effect is realized on the belt 5. Because not only through increasing the friction and rectifying, reduced the wearing and tearing of friction to belt 5, prolonged the life of belt 5. And through setting up friction pulley 23 automatic deviation rectification, can accurately rectify a deviation to belt 5.

In addition, the base 1 is a hollow cavity structure, the swing rod 26 and the connecting rod 3 are both arranged in the base 1, the protection effect on the connecting rod 3 is achieved, and meanwhile the influence of external interference on the rotation of the rotating shaft 24 is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
