Description

Technical Field

[0001] The utility model relates to the technical field of sealing high-barrier composite packaging bags, in particular to a sealing mold device for high-barrier composite packaging bags. Background Art

[0002] At present, high-barrier packaging, that is, packaging materials with high barrier properties, mainly includes PVDC, EVOH, PE, nitrile resin, polyamide, etc. The characteristics of PVDC and PVDC (polyvinylidene chloride) are low permeability, barrier properties and chemical resistance.

[0003] Among them, after the high-barrier composite packaging bag is used to package the material, the port of the high-barrier composite packaging bag needs to be sealed by a sealing device to prevent the material from leaking out of the high-barrier composite packaging bag, thereby facilitating the transportation of large quantities of materials.

[0004] However, when sealing high-barrier composite packaging bags through sealing devices in the market, it is difficult to ensure that the heating block is fully in contact with the high-barrier composite packaging bags, and incomplete sealing occurs. Moreover, there is no demoulding mechanism after sealing, resulting in the high-barrier composite packaging bags being in contact with the heating block for a long time, which may cause the high-barrier composite packaging bags to melt. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a sealing mold device for a high-barrier composite packaging bag, which solves the problems raised in the background technology.

[0007] The sealing and demolding mechanism includes mounting parts fixedly installed on both sides of the bottom of the pressure plate, an elastic band fixedly installed between the two groups of mounting parts, a heating block fixedly installed at the bottom of the elastic band, a docking groove opened in the middle of the top of the base, a partition frame installed on one side of the bottom of the pressure plate, a pressure roller rotatably installed on one side of the bottom of the partition frame, and a partition roller rotatably installed on the other side of the bottom of the partition frame, and the docking groove and the heating block correspond to each other.

[0008] As an optional solution of the technical solution of the present application, the pressure roller is located at the top of the elastic belt, and the separation roller is located at the bottom of the elastic belt.

[0009] As an optional solution of the technical solution of the present application, each group of piston rods has a spring sleeved on its outer wall, and both sides of each group of springs are fixedly mounted to the base and the side wall of the limiting ring respectively, so as to support the piston rod.

[0010] As an optional solution to the technical solution of the present application, a screw is rotatably installed in the inner cavity of the pressure plate, and a moving block is threadedly installed on the screw. A limiting groove is opened on one side of the inner cavity of the pressure plate, and the limiting groove is slidably connected to the moving block. The side wall of the moving block is fixedly installed on the top of the partition frame, so as to limit the moving block.

[0011] As an optional solution of the technical solution of the present application, a motor is fixedly installed on one side of the inner cavity of the pressure plate, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one side of the screw, which can drive the screw to rotate.

[0012] As an optional solution of the technical solution of the present application, a controller is fixedly installed on one side of the base, and the controller is connected to the heating block through a wire to control the heating block.

[0015] 2. The technical solution of this application is that a moving block is installed on the screw thread, and the moving block is slidably connected to the limiting groove opened on one side of the inner cavity of the pressure plate. When the operator drives the motor to drive the screw to rotate, the limiting groove can drive the moving block connected to the screw thread to move left and right, so that the partition frame at the bottom of the moving block moves up and down and left and right along the heating block, thereby efficiently sealing and demolding the high-barrier composite packaging bag.
