Problems solved by technology

[0004] Therefore, at present, the composite method between two materials with different hot-melt temperatures is mostly carried out by viscose, and there are many such products on the existing market. For example, the middle layer is made of foaming materials such as PE, while the surface layer is It is made of polymer materials such as PVC, PU, ​​EVA, TPU, etc. At present, these products can only be compounded by glue, and the life of the products is generally short

Embodiment 1

[0061] Embodiment 1: a kind of multi-material composite machine, such as figure 1 As shown, the body 100, the lower mold 300 and the upper mold 200, the lower mold 300 is fixedly installed on the body 100 and forms a placing platform. Two vertical hydraulic cylinders 110 are installed on the body 100, the upper mold 200 is installed on the piston rods of the two hydraulic cylinders 110, four guide columns 130 are arranged on the body 100, and the upper mold 200 is slidingly installed on four on the guide post 130.

[0062] Two distance sensors 120 are installed on the body 100 above the upper mold 200, referring to the attached figure 2 , the two hydraulic cylinders 110 are arranged on the two parallel oil circuits, and the two hydraulic cylinders 110 are connected in series with the oil pump 111, and the two flow control valves 112 are respectively installed on the parallel oil circuits of the two hydraulic cylinders 110.

[0063] The two flow control valves 112 are contro...

Embodiment 2

[0075] Embodiment 2: as Figure 8 As shown, the difference from Embodiment 1 is that a temperature sensor 600 is provided on both sides of the heat shield 250 along the axial direction of the cooling channel 251, and the temperature sensor 600 can be installed on the heat shield 250, or infrared rays can be used. The thermal sensor is used for detection. In this embodiment, it is installed on the heat shield 250 as an example. A two-position four-way reversing valve is provided on the connecting pipe between the heat shield 250 and the pumping station 400 to control the medium delivery direction in the cooling channel 251 , and the two-position four-way reversing valve is controlled by two temperature sensors 600 .

[0076] When in use, the pump station 400 starts to cool the medium in the cooling channel 251. During the cooling process, the two temperature sensors 600 detect the temperature on both sides of the heat shield 250 in real time, and control the two-position four-w...

Embodiment 3

[0077] Embodiment 3: as Figure 9 As shown, the difference from Embodiment 1 is that no two-position four-way reversing valve is provided in this embodiment, and the number of cooling passages 251 in this embodiment is set in even numbers, and any two adjacent cooling passages 251 The flow direction of the medium is set in the opposite direction.

Abstract

The invention discloses a multi-material compounding machine which comprises a machine body, a lower die and an upper die. The lower die and the upper die are installed on the machine body, and a high-frequency generating device is arranged on the machine body; and the upper die comprises a high-frequency welding assembly electrically connected with the high-frequency generating device and a die pressing plate located below the high-frequency welding assembly, the die pressing plate comprises a heat conduction template and an electric heating piece, the end, away from the high-frequency welding assembly, of the heat conduction template is a working face, and the electric heating piece is located on the other end face of the heat conduction template or in the heat conduction template. A high polymer material has many electrons and can be heated through the high-frequency welding assembly, and the non-polymer material is electrically heated in the pressing process through the mold pressing plate, so that two different temperatures can be formed between the upper die and the lower die, the high polymer material and the non-polymer material can be molten respectively, the melting connection of the two materials is realized, and products suitable for the equipment need to meet the requirement that the melting temperature of the high polymer material must be higher than the melting temperature of the non-high polymer material.

Description

technical field [0001] The present application relates to the technical field of thermal lamination equipment, in particular to a multi-material lamination machine. Background technique [0002] At present, the composite methods of planar products are mainly divided into viscose connection and hot-melt connection. Among them, the viscose connection is to complete the connection between the two materials by setting glue between the two materials. The material is heated and is not affected by the hot melt temperature of the material, but its disadvantage is that the connection is not strong enough and the service life is short. It is mainly used in the matching products of two different materials. Due to the different melting temperatures of different materials, it cannot meet the melting state at the same time at one temperature. Although the temperature is heated to a high melting temperature, both materials can be melted. However, at this time, the material with a low melt...
