Heat-sealing mechanism of flat-plate-type blister packaging machine

Abstract

The invention relates to a heat-sealing mechanism of a flat-plate-type blister packaging machine. The heat-sealing mechanism comprises a heat-sealing cam, a spline spindle, a cam case, a cam case guide rod, an idler wheel seat, a lower mould guide plate, a heat-sealing lower mould, a formation material PVC, a heat-sealing aluminum foil, a blister filled with medicine, a heat-sealing upper mould and a heat-sealing heating plate. The heat-sealing mechanism also comprises an upward-downward movement mechanism which is arranged at the bottom of the cam case and can move upwards and downwards. The upper end of the upward-downward movement mechanism is provided with a cylinder piston connected with a jointing part of a pair of long connecting rods. The other ends of the long connecting rods are respectively connected with one end of a lower connecting rod and one end of an upper connecting rod. The other end of the lower connecting rod is fixed with a lower connecting rod seat connected with a heat-sealing upright post. The other end of the upper connecting rod is fixed with an upper connecting rod seat connected with the cam case. The top end of the heat-sealing upright post also comprises a buffering mechanism arranged on the heat-sealing heating plate. As a cylinder is arranged at the lowermost position of the heat-sealing mechanism, the whole height of the heat-sealing mechanism is reduced by 200 mm, the gravity center of the heat-sealing mechanism is lowered, and the stability of the operation of the heat-sealing mechanism is improved.

Description

technical field [0001] The invention relates to a flat type blister packaging machine, in particular to a heat sealing mechanism of the flat type blister packaging machine. Background technique [0002] Flat-type blister packaging machine is a kind of blister-type aluminum (PTP) / plastic (PVC), aluminum / aluminum, aluminum-plastic-aluminum, aluminum-plastic-aluminum Special equipment for compound sealing packaging [0003] The flat blister packaging machine is generally composed of a molding mechanism, a feeding mechanism, a heat sealing mechanism, an indentation mechanism, a molding material feeding mechanism (also called a traction mechanism), and a punching mechanism. [0004] Depend on figure 1 It can be seen that the cam box 3 is installed on the fuselage through the cam box guide rod 4, the heat-sealing column 12 is installed on the cam box 3, the cylinder base plate 15 is installed on the heat-sealing column 12, and the heat-sealing cylinder installed on the cylinder ...

AI Technical Summary

Problems solved by technology

[0005] However, in this structure, the heat-sealing cylinder is designed on the upper part of the fuselage. Due to the limitation of the height of the heat-sealing cylinder, the height of the whole machine reaches 1700mm
