Detailed Description

The invention is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 1 to 3, a bidirectional transmission device comprises a main body including a left shaft 2, a right shaft 8, a left shaft driving wheel set 4, a right shaft driven wheel set 10, a first conveyor belt set 5, a right shaft driving wheel set 7, a left shaft driven wheel set 11, a second conveyor belt set 6, a conveyor belt tensioning mechanism 3, a left power input wheel 1 and a right power input wheel 9.

As shown in fig. 2, the left axle driving wheel set 4 is fixed on the left axle 2 through a left key 12; the right shaft driven wheel set 10 is sleeved on the right shaft 8 through a right bearing 13, namely the right shaft driven wheel set 10 can freely rotate around the right shaft 8; the first belt conveyor set 5 is mounted on the left axle driving wheel set 4 and the right axle driven wheel set 10. When the left shaft 2 inputs power through the left power input wheel 1, the left shaft 2 drives the left shaft driving wheel set 4 to rotate, and drives the right shaft driven wheel set 10 to rotate through the first conveyor belt set 5.

As shown in fig. 3, the right axle driving wheel set 7 is fixed on the right axle 8 through a right key 14; the left shaft driven wheel set 11 is sleeved on the left shaft 2 through a left bearing 15, namely the left shaft driven wheel set 11 can freely rotate around the left shaft 2; the second conveyor belt group 6 is arranged on the right shaft driving wheel group 7 and the left shaft driven wheel group 11. When the right shaft 8 inputs power through the right power input wheel 9, the right shaft 8 drives the right shaft driving wheel set 7 to rotate, and drives the left shaft driven wheel set 11 to rotate through the second conveyor belt set 6.

The left shaft 2 and the right shaft 8 can move independently, so that the first conveyor belt group 5 and the second conveyor belt group 6 are driven to move independently. So that the whole transmission can simultaneously realize bidirectional movement.

The working principle is as follows:

as shown in fig. 1, 2 and 3, when power is input to the left power input wheel 1, the left shaft 2 rotates to drive the left shaft driving wheel set 4 fixed thereon to rotate, so as to drive the first conveyor belt set 5 and the right shaft driven wheel set 7 to move. Since the right shaft driven wheel set 7 is sleeved on the right shaft 8 through the right bearing 13, the rotation of the right shaft driven wheel set 7 does not affect the movement of the right shaft 8.

Meanwhile, power is input into the right power input wheel 9, the right shaft 8 rotates to drive the right shaft driving wheel group 7 fixed on the right shaft driving wheel group to rotate, and the second conveyor belt group 6 and the left shaft driven wheel group 11 are driven to move. Because the left shaft driven wheel set 11 is sleeved on the left shaft 2 through the left bearing 15, the rotation of the left shaft driven wheel set 11 does not influence the movement of the left shaft 2.

As described above, the left shaft 2 and the right shaft 8 can move independently, so as to drive the first conveyor belt group 5 and the second conveyor belt group 6 to move independently. Therefore, the whole transmission device can simultaneously realize bidirectional movement and bidirectional material transmission.

The first and second sets of conveyor belts 5, 6 may be belts, timing belts, chains or link plates. The bidirectional movement can here be a simultaneous movement to the left, a simultaneous movement to the right, a movement to the left and right in opposite directions, a movement to the left and right away. The direction of movement may be determined by demand and by the manner of control.

As shown in fig. 2 and 3, the push rod pushes the first and second conveyor belt groups 5 and 6 to the left, so that the first and second conveyor belt groups 5 and 6 can be tensioned, and the push rod pulls the right, so that the first and second conveyor belt groups 5 and 6 can be loosened.

FIG. 4 shows that the present invention can be applied to a three-station totally-enclosed sandblasting machine, and can realize various motion requirements of a conveying system in a smaller space.

By adopting the technical schemes, the invention has the following beneficial effects:

1. bidirectional movement can be achieved simultaneously. The bidirectional movement can simultaneously move leftwards, rightwards, leftwards and rightwards in opposite directions and move leftwards and rightwards in opposite directions. The direction of movement may be determined by demand and by the manner of control.

2. The bidirectional movement is realized in the same length space, the production efficiency is effectively improved, and the space is saved.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
