Hot-pressing sealing machine

Abstract

The invention provides a hot-pressing sealing machine. The hot-pressing sealing machine comprises a machine shell, a first hot-pressing assembly, one or more electromagnetic driving devices, one or more lifting swing arms and a second hot-pressing assembly, wherein the machine shell comprises a main body part and a hot-pressing table part located in front of the main body part, and an opening is formed in the top surface of the hot-pressing table part; the first hot-pressing assembly is arranged on the hot-pressing table part, and comprises a heater and a first hot-pressing knife edge, and the first hot-pressing knife edge is exposed to the opening, and is heated by the heater; the one or more electromagnetic driving devices are installed in the main body part; a first end of each lifting swing arm is connected with one corresponding electromagnetic driving device, a second end of each lifting swing arm extends out of the main body part, and the lifting swing arms are driven by the electromagnetic driving devices to ascend and descend; and the second hot-pressing assembly is connected with the second ends of the lifting swing arms, comprises a second hot-pressing knife edge, and is configured to enable the second hot-pressing knife edge and the first hot-pressing knife edge to form a heat-sealing area after the lifting swing arms descend to set positions, so that hot-pressing sealing is conducted on target packages in the heat-sealing area. According to the scheme, the hot-pressing sealing machine has a good sealing effect and high reliability.

Description

technical field [0001] The invention relates to packaging equipment, in particular to a heat-press sealing machine. Background technique [0002] The sealing machine refers to the machine that seals the container after the packaging container is filled with the product, among which the heat sealing machine is the most widely used one. [0003] The working principle of the hot-press sealing machine is: heat the material at the heating sealing place to make it reach a viscous flow state, and then pressurize it to make it stick and seal. The heat sealing head is the actuator of the heat press sealing machine. The heat sealing machine can seal various films or bags made of thermoplastic materials. According to the characteristics of different packaging materials, different heat sealing head structures and heating methods can be used. [0004] Common failures of heat sealing machines include: the seal is not sealed, the seal will crack with a little force, and even the seal wil...

AI Technical Summary

Problems solved by technology

[0004] Common failures of heat sealing machines include: the seal is not sealed, the seal will crack with a little force, and even the seal will be cut off directly. Most of the reasons are that the heat sealing temperature is too high or too low, the heat sealing speed is too fast or Too slow, although the existing heat press sealing machine provides a simple temperature adjustment control function, but generally rely on the experience of the operator to set up, limited by the level of the operator, it often takes a long time to adjust the parameters to adjust the new type packaging for high-volume operations

[0005] In addition, limited by the temperature control means, the heat sealing temperature of the existing heat sealing machine is prone to fluctuations, resulting in uncontrollable sealing quality and prone to quality defects
