Detailed Description

The utility model discloses an overcome prior art's defect, provide the unloading switching device of accurate feeder, it is right to combine the embodiment below the utility model discloses do further detailed description.

Example 1

The blanking switch device of the precise feeder comprises a controller, a multi-stage telescopic switch plate and a driving device. In this embodiment, the multi-stage retractable switch board is a 3-stage retractable switch board, and includes a primary board, a secondary board, and a tertiary board arranged from top to bottom.

The driving device comprises a first motion block 6, a second motion block 7 and a third motion block 8 which are respectively connected with one side of the primary plate, one side of the secondary plate and one side of the tertiary plate.

A penetrating strip-shaped hole is formed in the first motion block 6, a rotatable first gear set 9 is arranged in the strip-shaped hole, and the top and the bottom of the first gear set 9 exceed the top surface and the bottom surface of the first motion block 6. Still be equipped with the holding tank that sets up the direction the same with the bar hole in first motion piece 6 bottom, be equipped with first rack 11 in the holding tank.

A penetrating strip-shaped hole is formed in the second motion block 7, a rotatable second gear set 10 is arranged in the strip-shaped hole, and the top and the bottom of the second gear set 10 exceed the top surface and the bottom surface of the second motion block 7. Still be equipped with the holding tank that sets up the direction the same with the bar hole at second motion piece 7 top, be equipped with second rack 12 in the holding tank.

The top of third motion piece 8 is equipped with the holding tank, is equipped with third rack 13 in the holding tank.

Further, the bottom of the first gear set 9 is located in the second motion block 7 receiving slot and is engaged with the second rack 12. The top of the first gear set 9 is engaged with the driving gear. The driving gear is arranged at the output end of the motor.

The top of the second gear set 10 is meshed with a first rack 11 in the first motion block 6 accommodating groove; the bottom of the second gear set 10 is engaged with the third rack 13 in the receiving groove of the third motion block 8.

In this embodiment, the first gear set 9 and the second gear set 10 have the same structure, and both include a plurality of large gears and a plurality of small gears, and the small gears and the large gears are arranged in an interval meshing manner. The motor is engaged with one of the large gears of the first gear set 9. So that the motor works to drive the first gear set 9 to rotate, and the second rack 12 moves relative to the first gear set 9, thereby driving the second motion block 7 to move relative to the first motion block 6. Since the first rack 11 is engaged with the second gear set 10, during the movement of the second moving block 7, the first rack 11 drives the second gear set 10 to rotate. The third rack 13 engaged with the second gear set 10 moves relative to the second gear set 10 to drive the third moving block 8 to move. Therefore, the stretching of the first motion block 6, the second motion block 7 and the third motion block 8 can be controlled by controlling the positive rotation and the negative rotation of the motor.

Because one side of the first motion block 6, one side of the second motion block 7 and one side of the third motion block 8 are respectively and fixedly connected with the first-stage plate, the second-stage plate and the third-stage plate, the telescopic motion of the multi-stage telescopic switch plate is driven.

Furthermore, the top of the first-stage plate is connected with a slide block of a slide guide rail arranged at a feed opening of the upper storage bin. The motor dodges the feed opening of feed bin on to for it is located the feed opening outer wall outside. The setting direction of the rack is the same as that of the sliding guide rail.

The controller is connected with the driving device, and the controller controls the work of the driving device so as to control the stretching and retracting.

Adopt this embodiment drive arrangement drive multistage flexible switch board realize multistage extension, when switching device was in shutoff feed opening state, the switch board expandes, and the area is the biggest. When the switching device is in a state of opening the feed opening, the switching plate is contracted, the area of the switching plate is minimum, and the switching plate can be contracted to about 1/3 of the area of the feed opening. When opening the feed opening, other structures to in the feeder casing are dodged to it is relatively great to make to design the feed opening area when designing.

According to the above embodiment, the present invention can be well implemented. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
