Abstract

The utility model relates to a spring supporting roller set, which comprises a middle supporting roller 1, a joint 2, a side supporting roller 3 and a bottom beam 4. The utility model is characterized in that one end of the side supporting roller 3 is movably connected with the upper end of a movably supporting column 7, and the lower end of the movably supporting column 7 is connected with the bottom beam 4 by a pin shaft 8. The upper end of a supporting column assembly 6 is movably connected with the supporting column 7, and the other end is movably connected with the bottom beam 4. The utility model has the advantage of simple structure. The utility model can adjust the spring elastic force to adapt to the impact force of different fall, and can adjust the angle of the groove angle of the supporting roller set. The adjusting range of the angle is from 20 DEC to 35 DEG so that the height of the site belt is adapted.

Description

Spring supporting roller set

The utility model relates to mechanical tape type machinery, particularly is the spring-loaded idler group during adhesive tape type is carried.

The carrying roller group of using in the present all kinds of conveyer mainly is rubber rolling impact idler and the board-like impact idler of spring, and the former major defect is that it is big in freight volume, easy roll release when drop is big.The latter's major defect is that its pillar is fragile under big impulse force, the reason of its damage mainly be pillar with bottom girder between captive joint, be generally welding, under the effect of large impact power, weld zone often forms stress concentration, repeatedly impacts, easily form the metallo-fatigue damage, reduced its service life, and increased maintainer's maintenance load, increase cost and reduce work efficiency.

Goal of the invention of the present utility model is to disclose the adjustable groove angle angle of a kind of tool, has the carrying roller group of the impulsive force that adapts to different drops, to improve all kinds of travelling apron performances.

The technical solution that realizes goal of the invention of the present utility model is as follows: comprise middle idler roller 1, and joint 2, side carrying roller 3, bottom girder 4, its key is that side carrying roller 3 one ends and movable pillar 7 upper ends flexibly connect, movable pillar 7 lower ends are connected by bearing pin 3 with bottom girder 4; Pillar stiffener assembly 6 upper ends and movable pillar 7 flexibly connect, and the other end and bottom girder 4 flexibly connect.When middle idler roller 1 and side carrying roller 3 have pressure, because pillar stiffener assembly 6, movable pillar 7 and bottom girder 4 threes form stable gusseted, can guarantee the work of carrying roller group, when needs are adjusted groove angle, only need the end of pillar stiffener assembly 6 on bottom girder 4 fixing getting final product after translation on the bottom girder.

Therefore the utility model can be adjusted the groove angle angle easily, and because the elasticity adjusting of the recoil spring on the pillar stiffener assembly, to adjust the impulsive force that spring pressure adapts to different drops.Because stressed pillar assembly is a triangle, then put on movable pillar 7 and the pillar stiffener assembly 6 stressed dispersion respectively simultaneously by the pressure that transmits on the carrying roller, then improved the life-span of equipment, and stressed on the movable pillar 7 mainly act on bearing pin 3, in case bearing pin 3 damages, also very easily change

Make maintenance very convenient and cost is extremely low.

Provide concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view among Fig. 1.

See also Fig. 1 and Fig. 2, structure of the present utility model is as follows: comprise middle idler roller 1, it is main load-supporting part, side carrying roller 3, bottom girder 4, joint 2, it connects middle idler roller 1 and side carrying roller 3, key is that side carrying roller 3 one ends and movable pillar 7 upper ends flexibly connect, and movable pillar 7 lower ends are connected by bearing pin 8 with bottom girder 4; Pillar stiffener assembly 6 upper ends and movable pillar 7 flexibly connect, and the other end and bottom girder 4 flexibly connect.The carrying roller pillar that is made of movable pillar 7, pillar stiffener assembly 6 and bottom girder 4 is a triangular support, has goodish bearing force.

The structure of described pillar stiffener assembly 6 is to be nested with a spring 10 outside stem stem, and an end of stem stem is inserted in the movable tray 5, and movable tray 5 is fixed on the bottom girder 4.One end of stem stem and movable pillar 7 hinge joints, when the pressure that is transmitted by carrying roller acted on the pillar stiffener assembly 6, a part of masterpiece was used on the movable pillar 7, and a part acts on spring 10, and stem stem can slide in movable tray 5.

The structure of described movable tray 5 is to be connected with fixed block 12 by axle sleeve 11 at two ends of a cross oblique crank Z 9, and a through hole is arranged in the cross oblique crank Z 9.Stem stem then places through hole, and an end of stem stem is provided with an adjustment nut, by swivel nut, can adjust the elastic force of joint spring 10, and the stem stem lower end is equipped with setting nut 3, to adjust groove angle.

The utility model is by adjusting the position of movable tray 5 on bottom girder 4, can adjust the angle of groove angle, the scope of its adjustment is 20 °-35 °, therefore can adapt to on-the-spot belt height, because elasticity adjusting, the then adjustable roller group elastic force that puts one's child in a boarding nursery, and the pressure on the carrying roller group is to act on respectively on movable pillar and the pillar stiffener assembly, then makes the carrying roller group have quite high anti-impact force performance, the utility model is simple in structure, easy to maintenance, the saving fund is increased work efficiency.
