Description

Belt pulley tensioning device for automatic conveyor

Technical Field

The utility model belongs to the technical field of automatic conveying equipment's technique and specifically relates to a belt pulley overspeed device tensioner for automatic conveyor.

Background

The belt transmission is widely applied to various machines and equipment as a power transmission mode, and after a belt works for a period of time, the belt is loosened due to plastic deformation, so that the tension is reduced, and the power transmission effect is influenced. Therefore, it is necessary to check the belt tension of the pulley in time and re-tension the belt. The belt tensioning mechanism is used for adjusting the belt tension of the belt pulley, and the adjusting mode of the belt tensioning mechanism has two modes, one mode is to adjust the distance between the two belt pulleys, and the other mode is to adjust the pressing degree between the tensioning wheel and the belt by using the tensioning wheel, so that the purpose of adjusting the belt tensioning is achieved.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is in order to solve the problem that exists among the above-mentioned background art, provides a belt pulley overspeed device tensioner for automatic conveyor, through improving, can realize need not to establish straining device in addition, with the integrative design of drive mechanism, practices thrift the cost, avoids the emergence of phenomenon of skidding, improves transmission efficiency.

The technical scheme of the utility model is that: the flat belt tensioning device of the input machine comprises a transmission mechanism and a tensioning mechanism; drive mechanism include the panel, with panel fixed connection's worm gear speed reducer machine, sprocket, chain, axle head mounting, driving roll, roller, belt, the middle upper department of panel has a long waist shape hole, straining device include with panel fixed connection's tensioning piece, the middle department of tensioning piece side has a screw thread through-hole, screw rod and tensioning piece screw-thread fit. The screw rod is rotated to move the screw rod during working, the screw rod pushes against the shaft end fixing part to move, and the shaft end fixing part is fixedly connected with the roller shaft, so that the movement of the roller shaft is driven to compress the belt to realize the adjustment of the belt tensioning degree of the conveyor.

Drawings

The invention will be described in further detail with reference to the drawings and the detailed description

Fig. 1 is a front view of the present invention;

FIG. 2 is a front view of the present invention;

in the figure: 1 screw rod, 2 tensioning blocks, 3 and 4 shaft end fixing parts, 5, 8 and 9 chain wheels, 6 panels, 7 worm gear speed reducers, 10, 11, 13 and 14 roll shafts, 12 driving rollers, 15 belts and 16 chains.

Detailed Description

FIG. 1 shows an input machine flat belt tensioner including a drive mechanism and a tensioning mechanism. The transmission mechanism comprises a panel 6, a worm and gear speed reducer 7 fixed with the panel 6 through bolts, chain wheels (5, 9), a chain 16, shaft end fixing parts (3, 4), a roller shaft (10, 11, 13, 14) and a belt 15, wherein the worm and gear speed reducer 7 is driven by a motor during working, after the rotating speed of the worm and gear speed reducer 7 is reduced, a driving chain wheel 9 connected with an extending shaft of the worm and gear speed reducer 7 through a flat key is driven to rotate, then a driven chain wheel 5 is driven through chain transmission, a driving roller 12 connected with the driven chain wheel 5 through a key is further driven, and finally the roller shaft (10, 11, 13, 14) is driven by the driving roller 12 to form belt transmission as shown in figure 2.

The tensioning mechanism comprises a tensioning block 2 fixed with the panel 6 through bolts and a screw rod 1 in threaded fit with the tensioning block 2. After belt 15 worked a period, the area is because plastic deformation relaxes, can make the pulling force reduce, influences the transmission effect of power, at this moment rotatory screw rod 1 makes screw rod 1 remove along screw rod axis direction, removes in-process screw rod 1 and can push up shaft end mounting 3 and slide along the long waist circular slot of panel 1, and shaft end mounting 3 adopts the fix with screw with roller 11 to the removal that drives roller 11 compresses tightly belt 15 and realizes the regulation of conveyer belt tensioning degree.
