Suction plastic packing machine

Abstract

The invention relates to a plastic suction sack filler; wherein, a temperature control mechanism adopts a PID mode to control a temperature control instrument; a knife rest in a longitudinal shutdown mechanism is an integrated knife rest; the lifting cylinders in a plastic suction mechanism and a heat seal mechanism are respectively provided with a gasket with a thickness of 40mm; a guide plate is arranged on a color control patch detecting mechanism; a solenoid pilot actuated valve in a power mechanism is arranged adjacent to the cylinder in the plastic suction mechanism; clutches in a film unreeling mechanism and a paper unreeling mechanism adopt electromagnetic clutches; a die sealing mechanism on a lower die in the plastic suction mechanism and the heat seal mechanism is formed by a rectangle groove arranged around the lower die and a heteromorphic joint strip embedded in the groove. The invention can control the heating temperatures of the plastic suction mechanism and the heat seal mechanism within an accurate and proper range, thus greatly improving the stability of plastic suction forming and heat seal forming, reducing gas consumption and effectively improving the productivity effect of the whole machine.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a blister packaging machine. Background technique [0002] In the medical device industry, blister packaging machines are widely used for packaging small products. It mainly includes a body and a film unwinding mechanism, a blister mechanism, a printing mechanism, a heat sealing mechanism, and a paper unwinding mechanism arranged on the body in the order of process steps. , Transverse cutting mechanism, vertical cutting mechanism and winding mechanism and corresponding automatic control mechanism, heating mechanism and power mechanism. During the use of the prior art blister packaging machine, the following problems are exposed: 1. The temperature control of the heating mechanism adopts a temperature control module, which is controlled by a switch, and the temperature difference range is large, between ±10-15°C. To make heat sealing and molding unstable; 2. In its longitudinal cutting mech...

During the use of the prior art blister packaging machine, the following problems are exposed: 1. The temperature control of the heating mechanism adopts a temperature control module, which is controlled by a switch, and the temperature difference range is large, between ±10-15°C. To make heat sealing and molding unstable; 2. In its longitudinal cutting mechanism, the longitudinal knife is assembled in sections, which is easy to cut off, causing small-sized products to easily break the film; 3. In its paper unwinding mechanism, because there is no
