Valve bag high-frequency rapid heating sealing device

Abstract

The invention relates to a valve bag high-frequency rapid heating sealing device. The valve bag high-frequency rapid heating sealing device is provided with an installation supporting seat, an adjusting air cylinder is hinged to the front side part of the installation supporting seat, lower connecting rods are hinged to the bottoms of the left side and the right side of the installation supportingseat separately, upper connecting rods are hinged to the upper portions of the left side and the right side of the installation supporting seat separately, and one end of each upper connecting rod and one end of each lower connecting rod are hinged to the installation supporting seat. The other ends of the upper connecting rod and the lower connecting rod are jointly hinged with a support plate.A fixed seat is arranged at the front part of the support plate, and a high-frequency heating sensor is arranged at the lower end of the fixed seat. Heat conduction seat cylinders are hinged to the left side and the right side of the front part of the support plate through mounting plates separately, the lower ends of piston rods of the heat conduction seat cylinders on the two sides are jointly hinged to a heat conduction seat plate, and a heat conduction seat is mounted on the heat conduction seat plate. The valve bag high-frequency rapid heating sealing device is high in heating efficiency,capable of achieving intermittent heating, low in loss, compact in structure, capable of saving installation and use space, adjustable in bag opening sewing angle of the whole device, high in adaptability and good in actual use value.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a high-frequency rapid heating and sealing device for valve pockets. Background technique [0002] At present, in the packaging industry, the commonly used sealing method for bagged materials is usually to use electric heating tubes for continuous heating, and the temperature control is to control the temperature of the electric heating tubes by transmitting signals from thermocouples or thermal resistors to thermometers. [0003] There are two ways of continuous heating: 1. Continuous bag supply; 2. Single bag heat sealing. The first type of bag is heated during walking and conveying, and the second type is single bag pressed against the heat seal. The heating power of these two methods of heat sealing is small, the temperature is low, and the time is long. If there is no bag supply, it will continue to maintain the heating and constant temperature working state, s...

However, the frequency of the commonly used vibrator is 20-30KHz, and the lower the frequency of the vibrator, the greater the output power, and the longer its horn will be used. Since the domestic vibrator does not have high frequency and high power, the transducer becomes Due to the size of the web and the heating die, the space cannot meet the requirements when used in our valve pocket heat sealing equipment
