Heat sealing mechanism capable of preventing heating wire from being broken and used for packaging machine

Abstract

The invention relates to the technical field of heat sealing mechanisms of packaging machines, in particular to a heat sealing mechanism for a packaging machine and capable of preventing a heating wire from being broken. Comprising a heat-sealing platform, an opening, an upper heat-sealing copper plate, a lower heat-sealing copper plate, a heating wire body and a driving mechanism, wherein the opening is formed in the heat-sealing platform and used for bagging; the upper heat-sealing copper plate and the lower heat-sealing copper plate are used for heat sealing; the heating wire body is used for heating; the two ends of the heating wire body are connected with elastic adjusting mechanisms through detachable fixing mechanisms, the elastic adjusting mechanisms are used for achieving self-adaptive movement through temperature changes generated by starting and stopping of work of the heating wire body, the heating wire body is prevented from being broken, the service life of the heating wire body is prolonged, and the service life of the heating wire body is prolonged. The heating wire has the advantages that the heating wire body does not need to be replaced regularly, time, labor and cost are saved, meanwhile, the heating wire body is kept tight, bubbles or incomplete heat sealing due to bending are avoided, the heat sealing effect is guaranteed, and defective and unqualified products are avoided.

Description

technical field [0001] The invention belongs to the technical field of heat-sealing mechanisms for packaging machines, and in particular relates to a heat-sealing mechanism for packaging machines that prevents heating wires from breaking. Background technique [0002] The packaging machine is mainly to automatically bag and seal the materials, and finally realize the packaging. Generally, the materials are loaded into the funnel, and then the two sides of the packaging bag are clamped by the manipulator, and the two sides of the packaging bag are sucked by the suction structure. Suction, and then the material in the funnel will enter the packaging bag. After the amount is filled, the manipulators on both sides move in reverse to straighten the bag mouth, and then push the heat seal strips on both sides to move relatively through the cylinder until the bag mouth is heated. The sealing is completed. During this process, the heat-sealing mechanism of the packaging machine is he...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a heat-sealing mechanism for a packaging machine that prevents the heating wire from breaking, so as to solve the problems caused by thermal expansion and contraction of the heating wire in the traditional packaging machine heat-sealing mechanism proposed in the above-mentioned background technology. There is ductility, but the traditional heat sealing mechanism does not reserve space, so that the ductility of the heating wire cannot be released, causing damage to itself and breaking, and at the same time, there is no guarantee that the ductility of the heating wire can be released. The structure that ensures the tightness of the heating wire leads to the problem of poor hot air effect
