Description

Automatic separating mechanism for plastic uptake box
Technical Field
The invention relates to the technical field of packaging machinery, in particular to an automatic separating mechanism for a blister box.
Background
At present, the type of packaging machinery in China mainly relates to filling, packaging, paperboard processing and the like of beverages and liquid foods. Meanwhile, the export countries of food packaging machinery in China mainly concentrate on southeast Asia, the middle east, south America, Africa and the like.
At present, the following methods are mainly used for separating the plastic uptake box:
1. manual separation is adopted. And directly taking out the plastic uptake boxes which are stacked together one by adopting a manual method. However, the labor cost spent by production enterprises is high, meanwhile, workers cannot be in a production cycle with high labor intensity for a long time, the workers can be tired after working for a long time, the operation precision and the efficiency are reduced, the edges of the plastic suction boxes are sharp, and the production accidents that the fingers of the workers are scratched easily occur in fatigue production.
2. And the friction wheels are adopted for matching and separating. Two parallel friction wheels with equal height are arranged on two sides of the plastic uptake box, and when a separation instruction is sent out, the friction wheels move upwards and gradually approach the plastic uptake box stacked at the bottommost. After the plastic-absorbing box is clamped by the two friction wheels, the friction wheels rotate inwards to enable the plastic-absorbing box at the bottommost part to be separated from the original position, then the friction wheels bring the plastic-absorbing box to return to the original position, and the separation process is finished. The friction wheel separation mode cannot solve the problem that negative pressure exists between adjacent plastic suction boxes, so that when a single plastic suction box is separated, equipment still has the possibility that a plurality of stacked plastic suction boxes are separated at one time due to the negative pressure between the boxes, the production cost is influenced, and the inconvenience is caused for the design of a subsequent box packing mechanism.
Aiming at the separation problem of the piled plastic uptake boxes, no good automatic solution is provided in the market at present. The thickness of the common plastic uptake box is only 0.14mm, the texture is very soft and easy to deform, the average gap between the piled plastic uptake boxes is only 1.5mm, the manufacturing precision of the plastic uptake box is poor, the width error of the edge can reach 5mm at most, and almost one side has no edge at all.
