Description
Technical Field
The invention relates to the field of developer supply, in particular to a developer supply device.
Background
In the past, there have been known described apparatuses employing a system involving a bellows pump disposed in a developer replenishment container to discharge developer. The specific method comprises the following steps: the whole developer replenishing container is complex in structure, multiple groups of connecting mechanisms exist, the number of kinematic pairs is too large, and when the container is assembled with equipment, the corresponding connecting rods are pushed open by fixing bone positions in the equipment to achieve the purpose of opening a developer replenishing opening preliminarily; then the container is continuously installed in the device, the ejection bone position in the developer receiving opening of the corresponding toner cartridge in the device abuts against the connecting rod on the developer replenishing opening of the container, and the connecting rod drives other connecting rods to further open the developer replenishing opening in the container, so that the developer replenishing opening of the container is completely attached to the developer receiving opening in the device. On the other side where the developer is easy to supplement, a driving wheel is matched with the inside of the equipment, the gear on the container side cover is driven to transmit through the rotation of the driving wheel, and the gear on the container side cover simultaneously drives the small rotating shaft and the large rotating shaft inside the container to rotate, so that the purpose of conveying the developer is achieved. In addition, in the known described device, the fit clearance between the rotating shaft and the side wall of the container is sealed by using silica gel.
However, in the actual production process, since the developer supply container is too complicated, there are many kinematic pairs, and many places thereof need to be assisted by springs, there is a certain probability that the connecting rods of the respective kinematic pairs are not installed or misinstalled when the developer receiving container is actually produced and assembled, and the more complicated the product, the higher the probability of error. In assembling the developer supply container into the apparatus, it is necessary to cooperate various parts in the apparatus to open the developer receiving container for its normal operation. It is thus presumed that, if one of the portions fails to fit, the developer supply container will fail to function.
On the other hand, in the known supply container, in the production or transportation process, the connecting rod is touched by mistake, so that the powder outlet of the developer replenishing container is opened, the developer flows out of the developer supply container, and the developer leakage phenomenon is caused; on the other hand, in the known supply container, the chip is matched with a machine, and a kinematic pair similar to a rotating shaft cam is adopted to achieve the purpose of matching the chip with the machine in a lifting way, but the potential problem of dead angle jamming exists, and poor reading of the developer supply container is caused.
