Description

Belt tensioning device for grinder head

Technical Field

The utility model relates to a grinder head belt tightener.

Background

After the transmission belt of the grinding machine head is used for a period of time, the transmission belt can be loosened due to the traction of long-time driving machinery, so that the conditions of slipping, loosening and the like in the transmission process are caused. The tensioner can be tensioned by increasing its radial formation after the belt has slackened. The existing tensioning equipment generally realizes tensioning through a tensioning wheel, but because the tensioning wheel is not suitable for a grinding machine, a device with simple structure and low cost is urgently needed to realize the tensioning action of a belt on the grinding machine.

SUMMERY OF THE UTILITY MODEL

In view of the not enough of prior art, the utility model aims to solve the technical problem that a grinder head belt tensioning device is provided, not only simple structure is reasonable, uses convenient high efficiency moreover.

In order to solve the technical problem, the technical scheme of the utility model is that: the belt tensioning device for the grinding machine head comprises a belt, wherein the belt is installed in a belt pulley groove of two belt pulleys, a fixed frame for supporting and fixing the two belt pulleys is arranged outside the two belt pulleys, one side of the fixed frame is screwed and horizontally extended from the outside to the inside through a screw, a tensioning device is fixedly connected to the inner end of the screw, and the tensioning device is connected with the outer side of the middle part of the belt between the two belt pulleys in a jacking mode.

Further, overspeed device tensioner is provided with the pivot including both sides board, leans on interior one side between the board of both sides to be provided with, and this pivot overcoat is equipped with the tensioning roller that can follow the pivot rotation, tensioning roller surface and belt surface contact, lean on outer one side to set firmly the connecting block between the board of both sides, link firmly with the screw through this connecting block.

Furthermore, both sides board is all coaxial to be run through and has been seted up the through-hole, all installs the bearing in this through-hole, the pivot both ends level extends to and realizes rotatoryly in the two shaft couplings.

Furthermore, two nuts are externally screwed on the screw, and the two nuts are respectively screwed on the inner side and the outer side of the fixing frame for fixing.

Compared with the prior art, the utility model discloses following beneficial effect has: through this grinder head belt tensioning device, the condition such as skidding, pine take off of having solved among the grinder head belt transmission process, it is safer, the device only need the adjusting screw position can realize simultaneously, easy operation is convenient, and is with low costs, has stronger practicality and wide application prospect.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic view of a usage status of the embodiment of the present invention;

fig. 3 is a schematic view of an actual position and an installation of the embodiment of the present invention.

In the figure: 1-belt, 2-belt pulley, 3-fixed frame, 4-screw, 5-tensioning device, 6-side plate, 7-rotating shaft, 8-tensioning roller, 9-connecting block, 10-through hole, 11-bearing and 12-nut.

Detailed Description

As shown in fig. 1-3, a belt tensioning device for a grinder head comprises a belt 1, wherein the belt is installed in a belt pulley groove of two belt pulleys 2, a fixed frame 3 for supporting and fixing is arranged outside the two belt pulleys, one side of the fixed frame is screwed and horizontally extended from outside to inside through a screw 4, a tensioning device 5 is fixedly connected to the inner end of the screw, and the tensioning device is connected with the outer side of the middle part of the belt between the two belt pulleys in a jacking mode.

The embodiment of the utility model provides an in, overspeed device tensioner is provided with pivot 7 including both sides board 6, by interior one side between the board of both sides, and this pivot overcoat is equipped with can be along with the rotatory tensioning roller 8 of pivot, tensioning roller surface and belt surface contact, the one side outside leaning on between the board of both sides has set firmly connecting block 9, links firmly with the screw through this connecting block.

The embodiment of the utility model provides an in, the equal coaxial through-hole 10 of having seted up of both sides board, all install bearing 11 in this through-hole, the pivot both ends level extends to and realizes rotatoryly in the two couplings.

In the embodiment of the present invention, the screw is externally screwed with two nuts 12, and the two nuts are respectively screwed inside and outside the fixing frame for fixing.

The utility model discloses theory of operation of embodiment: when the phenomenon of lax appears in the belt, at first loosen two nuts soon, reserve enough space for the screw is rotatory inwards, swivel nut after that, make the screw level move inwards, drive the connecting block level and move inwards, back both sides board will drive the tensioning roller level and move inwards and make the belt indent inwards warp, and then make the belt no longer lax in the department of contacting with the belt pulley, the condition such as skidding, pine take off of final solution transmission in-process.

The present invention is not limited to the above preferred embodiments, and any one can derive other various forms of the belt tensioner for a grinder head according to the teaching of the present invention. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
