What is the working principle of the manual plastic bag sealing machine?
Working principle of manual plastic bag sealing machine:Plastic bag sealing machine is suitable for aluminum foil bag, plastic bag, compound bag and ideal sealing machine in medicine, pesticide, food, daily chemical, lubricating oil and other industries. The sealing machine is designed and manufactured on the basis of the advanced models at home and abroad, as well as the function of vertical and horizontal sealing. Applicable to all plastic film sealing and bag making, food factory, cosmetics factory, pharmaceutical and other units of the ideal sealing equipment, continuous operation, but also according to user needs to date, batch number, etc.. Suitable for assembly line work.
Principle and structure of plastic bag sealing machine:1. The machine is composed of frame, speed reducer, transmission mechanism, heating and cooling mechanism, sealing printing mechanism, conveying device and electrical and electronic control system.2, the power supply, the agencies began to work. Electric heating element is energized after heating, the heating block and rapid heating control system to adjust to the desired temperature; pressure wheel rotation; according to the needs of the cooling system on cooling; conveyor belt transfer, and by the speed control device can be adjusted to a desired speed.3, when equipped with the packaging of goods placed on the conveyor belt, sealing parts are automatically sent to the two bags in the operation of sealing tape and into the heating zone, heat sealing block through the belt transmission to the sealing part of the bag, the thin film heating molten soft, then through the cooling zone, the film surface temperature properly decreased then after a knurled wheel (or wheel rolling), so the sealing part on the plastic film sticking and pressing a reticulated pattern (or printed logo), and then by the guide rubber belt and conveyor belt will be sent packing bag sealed, complete sealing operation.
By heating the plastic material and then heating is a fusion plastic wrap to prevent sticking up plastic bags
