Description

Technical Field

[0001] This utility model relates to the field of composite bag processing technology, specifically to a heat-sealing device for welding nozzles of food composite bags. Background Technology

[0002] Composite bags are made of two or more materials bonded together by machine with adhesive. They have advantages such as high strength and immunity to humidity changes, which makes them widely used in packaging for food, pharmaceuticals, chemicals, building materials and other industries. Composite bags need to be processed by heat sealing equipment.

[0003] Existing technologies, such as CN 216581433 U, describe a sealing device for composite aluminum foil bags. Before sealing the composite aluminum foil bags, the sealing area is compressed to expel air. At this time, no heat pressing is performed, which ensures that the two different materials are tightly attached and that no wrinkles will appear during heat sealing. The heat sealing effect is good, and the pass rate is improved.

[0004] However, this device still has some shortcomings in its use:

[0005] 1. Since the sealing assembly is in a fixed position, it is inconvenient to adjust it during operation. If it is necessary to heat seal composite bags of different sizes, the operator may need to frequently change equipment or adjust the position of the composite bags, which reduces work efficiency.

[0006] 2. When using this device, it is still difficult to guide the composite bag by means of the conveyor belt alone. The conveyor belt may not be able to provide sufficient guiding force, causing the composite bag to deviate during the conveying process, which affects the heat sealing effect. Utility Model Content

When using this device, it is still difficult to guide the composite bags by means of a conveyor belt alone, and the conveyor belt may not be able to provide sufficient guiding force, causing the composite bags to deviate during the conveying process, affecting the heat-sealing effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A heat-sealing device for welding nozzles of composite bags for food use includes a support plate, on the top of which a heat-sealing component and an auxiliary component are respectively disposed, and the auxiliary component is located at the bottom of the heat-sealing component;

One end of the spring telescopic rod is connected to the moving block, and the other end is connected to the heat sealing knife. The setting of the spring telescopic rod gives the heat sealing knife a certain buffering capacity during the movement, which can adapt to composite bags of different thicknesses and ensure the heat sealing effect.

[0020] 2. In this utility model, the control and efficient operation of the heat sealing process are achieved by setting up a guide roller, a rotary motor, a driven gear, a drive gear, a base, and a knife groove. The guide roller ensures the smooth transport of the composite bag during the heat sealing process and avoids poor sealing caused by bag misalignment. The rotary motor drives the meshing of the drive gear and the driven gear, thereby driving the guide roller to rotate, which facilitates the guiding operation of the composite film. The heat sealing knife reciprocates in the knife groove on the base. The knife groove enables the heat sealing knife to maintain a stable trajectory during movement, further ensuring the sealing quality. Attached Figure Description
