[0034] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0035] Example

[0036] like Figure 1-Figure 8As shown, a multi-layer composite device for manufacturing bio-based materials proposed in one embodiment of the present invention is mainly used to accurately stack, heat, soften and press different layers of bio-based materials to form a composite material with a multi-layer structure. The equipment is mainly composed of a workbench 1, a positioning seat 2, a pressing part 3, a hydraulic cylinder 4, a heating element 9, a material rack part 1 6, a material rack part 2 7 and an inflatable element 5. The workbench 1 is the foundation of the entire equipment and carries all components of the equipment. It is usually made of a sturdy and easy-to-clean material to ensure the stability and service life of the equipment. The positioning seat 2 is arranged on the top of the workbench 1, and its main function is to position and fix the bio-based material to be pressed. The positioning seat 2 is designed with an appropriate groove or clamping mechanism inside to ensure that the material will not be offset during the pressing process. The pressing part 3 is located above the positioning seat 2 and is driven by the hydraulic cylinder 4 to rise and fall. The bottom of the pressing part 3 is usually equipped with a pressing plate made of rubber or other soft materials to ensure that the material will not be damaged during the pressing process. The hydraulic cylinder 4 is the power source for driving the pressing part 3 to rise and fall. By controlling the extension and contraction of the hydraulic cylinder 4, the pressure of the pressing part 3 on the material can be accurately controlled to ensure the pressing effect. The heating element 9 is installed at the bottom of the positioning seat 2 to heat and soften the material in the positioning seat 2. The heating element 9 usually adopts heating elements such as electric heating wires and electric heating tubes, and the precise control of the temperature is achieved by controlling the on and off of the heating element. The material rack part 1 6 and the material rack part 2 7 are respectively composed of a mounting plate 1 61 and a mounting plate 2 71, which are installed on both sides of the positioning seat 2. Their main function is to overhead and layer the materials of each layer to prevent the materials from sticking or dislocating during the pressing process. The mounting plate 1 61 and the mounting plate 2 71 are respectively located on both sides of the positioning seat 2, and are installed with a pull plate 1 62 and a pull plate 2 72 that can be inserted into the positioning seat 2. When it is necessary to insert the material, the pull plate 1 62 and the pull plate 2 72 are pulled out; when the material is placed, the pull plate 1 62 and the pull plate 2 72 are inserted into the positioning seat 2 again, and the material is suspended. The inflatable member 5 is set on one side of the positioning seat 2 and connected to the positioning seat 2 through a pipeline. The function of the inflatable member 5 is to remove dust from the material in the positioning seat 2 before pressing, and to form an air curtain during the pressing process to prevent dust pollution. When the inflatable member 5 is started, it will generate an airflow, enter the positioning seat 2 through the pipeline, blow away the dust on the surface of the material, and form a layer of air curtain around the material to protect the material from external pollution.

[0037] Operation process

[0038] The bio-based material to be pressed is placed in the positioning seat 2, and the pull plate 1 62 and the pull plate 2 72 are pulled out. After all the materials are placed, the pull plates 1 62 and the pull plates 2 72 are reinserted into the positioning seat 2, the materials are suspended, the heating element 9 is started, the materials in the positioning seat 2 are heated and softened, the inflatable element 5 is started, the dust is removed from the materials and an air curtain is formed around them, the hydraulic cylinder 4 is controlled to descend, the pressing part 3 presses the materials, and after a certain pressing time, the hydraulic cylinder 4 is controlled to rise, and the pressed composite material is taken out. Through the above operation process, the multi-layer composite equipment for bio-based material manufacturing provided in this embodiment can efficiently and accurately complete the pressing work of multi-layer bio-based materials.

[0039] Among them, based on the first embodiment, the second embodiment makes a number of optimizations and improvements to the multilayer composite equipment for manufacturing bio-based materials, aiming to further improve the performance and use efficiency of the equipment.

[0040] The surface of the positioning seat 2 is provided with a plurality of positioning grooves 21 at the positions of the material rack part 1 6 and the material rack part 2 7. These positioning grooves 21 are precisely designed to ensure that the pull plate 1 62 and the pull plate 2 72 can be inserted accurately, thereby improving the positioning accuracy and stability of the equipment. A baffle 22 is placed at the notch to further fix and support the material. A positioning block 23 is installed at the bottom of the surface of the baffle 22. The cooperation between the positioning block 23 and the positioning seat 2 ensures the stability and position accuracy of the baffle 22. The surface of the pressing part 3 is provided with a mounting frame 1 31 and a mounting frame 2 32, which are used to install the push rod 52 and the short rack 81 respectively. This design makes the structure of the pressing part 3 more compact and convenient for installation and maintenance. In addition, a cavity is also provided in the pressing part 3, including an air inlet 33 and an air outlet 34, which are used for the circulation of gas to further improve the dust removal and air curtain effect. A one-way valve 2 57 and a one-way valve 1 56 are installed on the surface of the air inlet pipe 55 and the air outlet pipe 54 respectively. These one-way valves ensure the one-way flow of gas during the inflation and exhaust process, prevent gas backflow, and improve inflation efficiency and safety. A mounting seat 63 is installed at the ends of the pull plate 1 62 and the pull plate 2 72, and a rotatable roller 64 is installed on the mounting seat 63. The roller 64 is in contact with the material. When the pull plate is inserted or withdrawn, the roller 64 can roll, thereby reducing the friction resistance between the material and the material, making the operation smoother and reducing the damage to the material.

[0041] Operation process

[0042] The bio-based materials to be pressed are placed in the positioning seat 2 in order, and the pull plate 1 62 and the pull plate 2 72 are pulled out, the baffle 22 is placed at the notch, and fixed by the positioning block 23. After all the materials are placed, the pull plate 1 62 and the pull plate 2 72 are reinserted into the positioning groove 21 of the positioning seat 2, the materials are suspended, the heating element 9 is started, the materials in the positioning seat 2 are heated and softened, the inflation element 5 is started, and the gas is filled into the positioning seat 2 through the air inlet pipe 55, the dust is removed from the materials, and an air curtain is formed around them, the hydraulic cylinder 4 is controlled to descend, and the pressing part 3 presses the materials. During the pressing process, the gas in the pressing part 3 is discharged through the air outlet 34 to form a circulating flow, further improving the dust removal and air curtain effects. After maintaining a certain pressing time, the hydraulic cylinder 4 is controlled to rise and the pressed composite material is taken out. Through the above improvements and optimizations, the multi-layer composite equipment for bio-based material manufacturing provided in Example 2 has significantly improved positioning accuracy, operation convenience, dust removal effect and safety, and can better meet the production needs of multi-layer composites of bio-based materials.

Material positioning and dust removal: inserting the material through the opening of the positioning seat 2, ensuring that the material is placed flat in the positioning seat 2, starting the inflatable element 5, extracting and spraying gas into the positioning seat 2, and purging the material through the air outlet 25. Dust is removed and an air curtain is formed to prevent dust; c. Material heating and softening: The heating element 9 is started to heat and soften the material in the positioning seat 2 for subsequent pressing; d. The material rack part moves and is pressed into shape: The hydraulic cylinder 4 begins to descend, and the pressing part 3 descends accordingly.
