Description

Intermittent variable-speed grinding device

Technical Field

The utility model belongs to the technical field of the manufacturing, especially, relate to an intermittent type formula variable speed grinder.

Background

At present, in the production and grinding process of ultrafine powder, a grinding machine or a ball mill is usually used for grinding, the grinding machine is used for grinding at a constant speed, and how to fully utilize impact power and rolling power is not considered in the grinding process, so that the efficiency is low, and the energy consumption and the time consumption are caused; and adopt ordinary uniform velocity motor, the start-up voltage is high in the twinkling of an eye, and power consumption is high, does not protect the motor, and is big to transmission part loss, and is required highly to the electric wire netting, and the start-up voltage in the twinkling of an eye is about 5 times of ordinary rated voltage, consequently needs to design a novel intermittent type formula variable speed grinder.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an effectual problem among the above-mentioned background of solution has proposed an intermittent type formula variable speed grinder, and concrete technical scheme is as follows:

an intermittent variable-speed grinding device comprises a driving device, an intermittent transmission device and a grinding device, wherein the driving device, the intermittent transmission device and the grinding device are arranged on a frame body (8); the intermittent drive device includes: the device comprises a driving wheel (1), a guide wheel (2) eccentrically fixed on the driving wheel (1), a guide frame (3), a gear (4) and a guide rod (3-1) arranged on the guide frame (3); the guide frame (3) is rotationally matched on the main shaft (5), the gear (4) is fixedly matched on the main shaft (5), and the driving wheel (1) is connected with the driving device;

preferably, the guide wheel (2) is provided with a square hole (2-1) and is connected with the driving wheel (1) through a fastening screw (6) arranged in the square hole (2-1);

preferably, the grinding means comprise a grinding wheel (7) mounted on the spindle (5);

preferably, the driving device is a driving motor (9);

compared with the prior art, the beneficial effects of the utility model reside in that: this variable speed grinder drives grinder through intermittent type formula pendulous device and carries out intermittent type formula grinding, increases the roll time of grinding medium, makes the roll work maximize of grinding, and the position adjustment of leading wheel on the action wheel is convenient for realize effective reasonable control grinding simultaneously, the protection motor, and in a word, the device improves grinding efficiency, practices thrift grinding time, reduces the grinding medium cost, protects the motor simultaneously.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the intermittent drive mechanism of the present invention;

in the figure: the grinding machine comprises a driving wheel 1, a guide wheel 2, a square hole 2-1, a guide frame 3, a guide rod 3-1, a gear 4, a main shaft 5, a screw 6, a grinding wheel 7, a frame body 8 and a driving motor 9.

Detailed Description

In order to make the technical personnel in the technical field understand the scheme of the invention better, the invention is further explained in detail with the attached drawings and the embodiment;

an intermittent variable-speed grinding device comprises a driving device, an intermittent transmission device and a grinding device which are arranged on a frame body 8; the driving device is a driving motor 9; the grinding device comprises a grinding wheel 7 arranged on the main shaft 5; the intermittent drive device includes: the device comprises a driving wheel 1, a guide wheel 2 eccentrically fixed on the driving wheel 1, a guide frame 3, a gear 4 and a guide rod 3-1 arranged on the guide frame 3; the guide wheel 2 is provided with a square hole 2-1 and is connected with the driving wheel 1 through a fastening screw 6 arranged in the square hole 2-1; the guide frame 3 is rotationally matched on the main shaft 5, the gear 4 is fixedly matched on the main shaft 5, and the driving wheel 1 is connected with the driving device;

the operation process of the device is as follows:

this device drives 2 eccentric rotations of leading wheel through the rotation of action wheel 1, and the eccentric rotation of leading wheel 2 drives leading truck 3 round main shaft 5 reciprocating swing, and the reciprocating swing through the leading truck drives the guide bar and pushes away gear 4 intermittently to drive grinder intermittent type nature rotation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
