High-speed flat plate heat sealing mechanism of hot pack machine

Abstract

The invention discloses a high-speed flat plate heat sealing mechanism of a hot pack machine. The heat sealing mechanism comprises an installation frame(4), a heat sealing device and a first lifting device; the heat sealing device comprises an upper heat sealing plate (13) and a lower heat sealing plate (8); the upper heat sealing plate is connected with an upper heating plate (12); the lower heatsealing plate is connected with a lower heating plate (7); and the upper heating plate (12) is connected with the first lifting device. The heat sealing mechanism is characterized in that corresponding receding grooves (14) are formed in the lower heat sealing plate (8) and the lower heating plate (7), high-magnetic magnets (15) are arranged in the receding grooves (14), and the high-magnetic magnets (15) are connected with a second lifting device. The heat sealing mechanism is simple in structure and reasonable in design, iron powder inside mechanism can be intensively adsorbed in the heat sealing process, the situation that the iron powder is disorderly blown to the edge position of the hot pack machine due to static electricity is avoided, the appearance of the edge of the hot pack machine after heat sealing is influenced due to the existence of the iron powder, and meanwhile, the waste of the iron powder is avoided.

Description

technical field [0001] The invention relates to the production equipment of the heating bag machine, in particular to a high-speed flat plate heat sealing mechanism of the heating bag machine. Background technique [0002] Warm baby is a one-time heating product. By rubbing the warming machine, the internal materials can react to generate heat, and then obtain the heating effect. Among them, iron powder is an indispensable heating material in the warming machine. Chinese patent document (publication number: CN203186637U, publication date: September 11, 2013) discloses a heat sealing device for a warm bag machine, including a mounting frame, a cam box, a heat sealing device, a lifting device and a column, the described The heat-sealing device includes upper and lower heat-sealing plates, upper and lower heating plates, a slide plate, and a fixed plate. Below the cam, the roller seat is arranged on the bottom plate, the cam box is fixedly connected with the installation frame...

AI Technical Summary

Problems solved by technology

[0003] The defect of the above structure is: since the packing bag of the warming machine has static electricity, when heat sealing is performed, the iron powder will scurry around in the warming machine bag due to static electricity, and some iron powder will move to the edge of the warming machine At the position, after the heat sealing of the warming machine is completed, the iron powder at the edge makes the edge of the warming machine look like there are many black spots, which affects its overall appearance. At the same time, this part of the iron powder is wasted, which is not conducive to the warming machine. usage of
