Description

Power transmission device for kneaders

The present invention relates to a power transmission device for the kneader, and in particular, the rotational force of the motor installed in the main body to be transmitted to the screw through a simpler path can significantly reduce the noise generated when the kneader driving, and to simplify the structure The present invention relates to a power transmission device for a kneader, which can reduce the failure and significantly reduce the overall size of the product.

1 and 2 illustrate a kneader to which a conventional power transmission device is applied.

Two screws (3) are inserted into the conveying pipe (2) mounted on the main body (1), and a driven sprocket is provided to the shaft bar (4) integrally formed on the rear surface of the screw (3) via a gear box (5). (6) is connected, and this driven sprocket 6 is connected by the drive sprocket 9 and chain 10 which were built up to the shaft rod 8 of the reducer 7. As shown in FIG.

Then, a motor 11 that rotates when voltage is applied is installed on the bottom surface of the main body 1, and the first pulley 12 built in the motor 11 and the second pulley 13 built in the reducer 7 are provided. ) Is connected by a belt (14).

As shown in FIG. 2, a first gear 16 is formed on the shaft of the driven sprocket 6, and the second gear 17 rotates in engagement with the first gear 16. Is installed on one side of the first gear 16, and the driving gear 18 on one side of the driving gears 18 and 19 that meshes with each other is rotated on the same axis as the second gear 17. .

On the axis of rotation of the drive gears (18) and (19), a screw (3) for kneading kneading is coupled, and reference numeral 15, which is not described, is a supply container for drawing in kneading material.

However, since the conventional power transmission device transmits the rotational force generated by the motor 11 to the screw 3 using a plurality of gears, belts and chains, the structure is very complicated, and a large noise occurs during operation. There is a problem that the size of the product is relatively large.

That is, conventionally, the first pulley 12 of the motor 11 and the second pulley 13 of the reducer 7 are connected by the belt 14, and such a belt 14 has a predetermined distance between the shafts. Since the power transmission is performed only without opening the svel phenomenon, the distance between the first pulley 12 and the second pulley 13 must be significantly increased, and for this reason, the size of the main body 1 becomes relatively large. Problems arise, and the belt 14 is stretched due to long use of the belt 14, and the belt 14 is often pulled out from the pulley.

In addition, since the driving sprocket 9 and the driven sprocket 6 of the reducer 7 are connected by the chain 10, severe noise is generated during driving, and the overall structure of the conventional power transmission device is very complicated, so that the production cost is high. It is increasing.

Accordingly, the present invention for solving the above problems is to transmit the rotational force of the motor installed in the main body to the screw through a simpler path can significantly reduce the noise generated when the kneader is driven, and the failure due to the simplification of the structure It is an object of the present invention to provide a power transmission device for a kneader which can be reduced and can significantly reduce the size of the overall product.

Hereinafter, with reference to the accompanying drawings Figures 3 and 4 will be described a preferred embodiment of the present invention.

According to the drawings, the subject innovation is formed on the inner side of the main body 30 is formed with a wheel for rolling on the bottom, and the motor 32 is installed in the vertical support 31 in this direction, the motor The rotating shaft of (32) was made to face upward, and the 1st gear 33 was formed in the edge part of this rotating shaft.

The drive shaft 35 is vertically coupled to the upper end of the main body 30 at the position opposite to the motor 32 by the bearing 36, and a second gear 37 is formed below the drive shaft 35 to form a second gear 37. The second gear 37 and the first gear 33 were connected by a timing belt 38.

On the upper side of the first gear 33 and the lower side of the second gear 37, the support protrusions 34a and 34b are projected outward, respectively, so that the timing belt 38 coupled to the respective gears 33 and 37 is supported. It was supported by the projections 34a and 34b so as not to peel off.

The reason for connecting between the first gear 33 and the second gear 37 as the timing belt 38 as described above is because the timing belt 38 rotates in engagement with the respective gears 33 and 37, and thus the interaxial distance. This is because power is normally transmitted irrespective of this, and the distance between the axes of the first gear 33 and the second gear 37 can be set closer thereto.

A gearbox 40 having a predetermined size is formed on the upper portion of the main body 30 on which the driving shaft 35 is formed, and the worm gear 41 is laid on the upper portion of the driving shaft 35 so as to be located inside the gearbox 40. On one side of the worm gear 41, a driven gear 42 was formed at one end of the rotation shaft 46, which was formed by the bosses 51 formed on both inner walls of the gear box 40.

The driven gear 42 is engaged with the worm gear 41 so that the driven gear 42 rotates when the worm gear 41 rotates. As the driven gear 42 rotates when the worm gear 41 rotates, the rotary shaft 46 ) Also rotated in conjunction.

In addition, a third gear 44 is formed at the other end of the rotation shaft 46, and a fourth gear 45 is formed to mesh with the third gear 44, but the rotation shaft of the fourth gear 45 ( 47) is supported by the boss 51 to the gearbox 40 so that the fourth gear 45 is interlocked and engaged when the third gear 44 rotates.

Both the rotary shaft 46 of the third gear 44 and the rotary shaft 47 of the fourth gear 45 are exposed to the side of the gearbox 40, and screws at the end of each rotary shaft 46, 47 Coupling pins 48 and 49 were formed to allow 50 to be coupled.

3 and 4 omit the illustration of the dough feed pipe surrounding the screw and the supply pipe for kneading material commonly used in the kneader.

Referring to the operation of the present invention configured as described above is as follows.

When the motor 32 operates and the first gear 33 rotates, the first gear 33 and the second gear 37 connected by the timing belt 38 interlock with each other to rotate. The worm gear 41 formed at the upper end of the drive shaft 35 of the gear 37 rotates in the same direction.

When the worm gear 41 rotates, the driven gear 42 engaged with the worm gear 41 rotates, and the third gear 44 formed on the same axis as the driven gear 42, that is, on the rotation shaft 46, rotates. As a result, the fourth gear 45 meshed with the third gear 44 rotates.

When the third gear 44 and the fourth gear 45 mesh with each other to rotate, the rotation shafts 46 and 47 of the respective gears 44 and 45 rotate so that The dough kneading is kneaded by rotating the screw for the dough kneading 50 is coupled to the end.

As described above, in the power transmission device of the present invention, the rotational force of the motor 32 is the first gear 33 → the second gear 37 → the worm gear 41 → the driven gear 42 → the third and fourth. The failure rate is remarkably reduced because it is supplied to the screw 50 through a relatively simple path in the order of the gears 44 and 45, and the timing belt (A) is a power transmission means of the first gear 33 and the second gear 37. 38) and without the use of power transmission means such as chains, it is possible to narrow the distance between the axes, which can significantly reduce the overall size of the product and also have the additional effect of reducing the noise generated during operation. It can be.

As described above, the present invention allows the rotational force of the motor installed inside the main body to be transmitted to the screw through a simpler path without using a belt or a chain, thereby significantly reducing the noise generated when the kneader is driven, Simplification of the structure of the transmission device can reduce the failure between each component, it is a power transmission device for the kneader to reduce the size of the overall product significantly.
