Description

Technical Field

[0001] This invention relates to the field of material composite equipment technology, and in particular to a multilayer composite equipment and composite method for manufacturing bio-based materials. Background Technology

[0002] Multilayer composite equipment for bio-based material manufacturing is used to stack and composite different types of bio-based materials together. This equipment plays a crucial role in the production process of bio-based materials, ensuring the stability of the multilayer structure in terms of physical and chemical properties, thus meeting various application requirements. Traditional multilayer composite equipment often suffers from the following problems during operation, especially in the material placement and pressing processes: After material placement, traditional multilayer composite equipment lacks an effective support structure, leading to misalignment or displacement of the material before pressing, affecting the quality of the composite material; poor dust removal: Before pressing, the unsealed internal environment of the equipment easily introduces dust, causing surface contamination of the composite material and affecting product quality. Simultaneously, the dust attached to the material itself is difficult to remove effectively; insufficient positioning accuracy: During material placement and pressing, the imperfect positioning structure of traditional multilayer composite equipment results in low positioning accuracy, affecting the interlayer alignment and uniformity of the composite material; low operational convenience: When inserting and removing support plates or other auxiliary tools, the high friction makes the operation cumbersome, reducing production efficiency and increasing the workload of operators. Summary of the Invention

The bottom of the positioning seat is equipped with a heating element for heating and softening the materials within the positioning seat. A hydraulic cylinder is installed on the top of the pressing part to drive its lifting and lowering. A first and a second material rack are inserted into the positioning seat, respectively, for suspending and layering each layer of material. The first and second material racks are symmetrically arranged relative to the positioning seat. An opening is provided on the surface of the positioning seat for inserting materials.

[0007] Preferably, a drive component is installed on the back of the positioning seat. The drive component is used to move the first and second material racks out of the positioning seat when the hydraulic cylinder moves downward, so as to facilitate the pressing and molding of the material in the positioning seat by the pressing part.

[0008] Preferably, the driving component includes a short rack installed at the pressing part, a rotatable small gear disk and a large gear disk are installed on the side of the positioning seat, the short rack and the small gear disk are meshed together, a large rack is installed at both the second and first parts of the material rack, the large gear disk and the large rack are meshed together, wherein the travel distance of the large rack is twice that of the short rack, a bevel gear one is installed at the large gear disk, a bevel gear two is installed at the small gear disk, and the bevel gear one and the bevel gear two are meshed together.

[0009] Preferably, the inflation component includes a push rod connected to the pressing part and an air storage tank installed on the top of the workbench. The push rod is inserted into the air storage tank, and a push plate is installed at the end of the push rod. The push plate is tightly fitted to the inner wall of the air storage tank. An air inlet pipe is installed on the side of the air storage tank. A cavity is opened in the positioning seat, and the air inlet pipe is inserted into the cavity. The inner wall of the positioning seat has multiple air outlet holes for air outlet at the cavity.

[0010] Preferably, the surface of the positioning seat is provided with multiple positioning grooves at both the first and second material racks. The positioning grooves are used for the insertion of the first and second pull plates. A baffle is placed at the notch of the positioning seat. A positioning block is installed at the bottom of the surface of the baffle. The positioning block is used to limit the position of the baffle.

[0011] Preferably, the pressing part includes a mounting bracket one and a mounting bracket two mounted on its surface. The mounting bracket one is used for mounting the thrust rod, and the mounting bracket two is used for mounting the short rack.

[0012] Preferably, a second one-way valve is installed on the surface of the air inlet pipe, and a first one-way valve is installed on the surface of the air outlet pipe. Both the second one-way valve and the first one-way valve are used for large one-way gas flow.

[0013] Preferably, a mounting base is installed at the end of both the first and second pull plates, and a rotatable roller is installed at the mounting base, the roller being in contact with the material.

[0014] A composite method for a multilayer composite device used in the manufacture of bio-based materials includes the following steps:

[0015] a. Preparation stage: Place the workbench in an appropriate position and ensure that all parts of the equipment are securely connected. Check the working status of key components such as hydraulic cylinders, heating elements, air inflators and drive components to ensure that there are no abnormalities. Prepare the bio-based materials to be composited and place them in sequence between the first and second shelf sections in the positioning seat, ensuring that each layer of material is suspended and layered.

[0016] b. Material positioning and dust removal: Insert the material through the opening of the positioning seat, ensuring that the material is placed flat in the positioning seat. Activate the inflation device to extract gas and spray it into the positioning seat. Remove dust from the material through the air outlet, and at the same time form an air curtain to prevent dust.

[0017] c. Material heating and softening: Activate the heating element to heat and soften the material inside the positioning seat for subsequent pressing;

[0018] d. Material rack movement and pressing: The hydraulic cylinder begins to descend, and the pressing part descends accordingly. At the same time, the drive unit starts to work. Through the linkage of the short rack, small gear plate, large gear plate and large rack, the material rack part one and material rack part two are moved out of the positioning seat to avoid interfering with the pressing. The pressing part continues to descend to press the material in the positioning seat into shape.

[0019] e. Post-molding processing: After pressing, the hydraulic cylinder rises, and the pressed part separates from the material; the composite material is taken out for subsequent processing or testing.

[0020] Compared with the prior art, the present invention provides a multilayer composite device and composite method for manufacturing bio-based materials, which has the following beneficial effects:

[0021] This multi-layer composite equipment for manufacturing bio-based materials uses a staggered insertion mechanism to effectively support the materials after they are placed inside. The device also features an air-blowing mechanism that creates an air curtain, preventing dust from entering and removing dust from the materials themselves. This ensures effective pressing of the materials.

[0022] This multilayer composite equipment for manufacturing bio-based materials incorporates a one-way valve and gas circulation within the pressing section through the design of the inflation component and pressing section. These improvements enable better dust removal of the material before pressing and create a more stable air curtain during the pressing process, effectively preventing dust contamination and improving the quality of the composite material.

[0023] This multi-layer composite equipment for manufacturing bio-based materials improves positioning accuracy by adding positioning grooves and blocks to the positioning seat design, allowing for more precise insertion of pull plates one and two. Simultaneously, the combination of baffles and positioning blocks further enhances the stability of the material during the pressing process, reducing the possibility of material misalignment or displacement.

[0024] This multi-layer composite equipment for manufacturing bio-based materials significantly reduces friction during the insertion and removal of the pull plates by installing rollers at the ends of pull plates one and two, thereby improving operational convenience. This improvement not only increases production efficiency but also reduces the workload of operators. Attached Figure Description

[0034] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0035] Example

[0036] like Figures 1-8As shown, an embodiment of the present invention proposes a multilayer composite equipment for manufacturing bio-based materials, primarily used for precisely stacking, heating and softening, and pressing different layers of bio-based materials to form a composite material with a multilayer structure. The equipment mainly consists of a worktable 1, a positioning seat 2, a pressing section 3, a hydraulic cylinder 4, a heating element 9, a first material rack 6, a second material rack 7, and an inflatable element 5. The worktable 1 is the foundation of the entire equipment, bearing all its components. It is typically made of a robust and easy-to-clean material to ensure the stability and service life of the equipment. The positioning seat 2 is located on top of the worktable 1, and its main function is to position and fix the bio-based material to be pressed. The positioning seat 2 has appropriate grooves or clamping mechanisms inside to ensure that the material does not shift during the pressing process. The pressing section 3 is located above the positioning seat 2 and is driven to rise and fall by the hydraulic cylinder 4. The bottom of the pressing section 3 is typically fitted with a pressure plate made of rubber or other soft material to ensure that the material is not damaged during the pressing process. The hydraulic cylinder 4 is the power source for driving the pressing section 3 to rise and fall. By controlling the extension and retraction of the hydraulic cylinder 4, the pressure of the pressing section 3 on the material can be precisely controlled, thereby ensuring the pressing effect. The heating element 9 is installed at the bottom of the positioning seat 2 to heat and soften the material inside the positioning seat 2. The heating element 9 usually uses heating elements such as heating wires and heating tubes. The temperature is precisely controlled by controlling the on and off of the heating element. The material support section 6 and the material support section 7 are respectively composed of mounting plate 61 and mounting plate 71, which are installed on both sides of the positioning seat 2. Their main function is to suspend and separate each layer of material to prevent the material from sticking or misaligning during the pressing process. Mounting plate 61 and mounting plate 71 are located on both sides of the positioning seat 2, and pull plate 62 and pull plate 72 that can be inserted into the positioning seat 2 are installed on them. When material needs to be inserted, pull plate 62 and pull plate 72 are pulled out; after the material is placed, pull plate 62 and pull plate 72 are reinserted into the positioning seat 2, suspending the material. The inflator 5 is located on one side of the positioning seat 2 and connected to it via a pipe. The function of the inflator 5 is to remove dust from the material inside the positioning seat 2 before pressing and to form an air curtain to prevent dust contamination during the pressing process. When the inflator 5 is activated, it generates an airflow that enters the positioning seat 2 through the pipe, blowing away dust from the material surface and forming an air curtain around the material to protect it from external contamination.

[0037] Operating procedures

[0038] The bio-based material to be pressed is placed in the positioning seat 2, and the pull plate 62 and pull plate 72 are pulled out. After all the materials are placed, the pull plate 62 and pull plate 72 are reinserted into the positioning seat 2 to suspend the material. The heating element 9 is activated to heat and soften the material in the positioning seat 2. The air inflation element 5 is activated to remove dust from the material and form an air curtain around it. The hydraulic cylinder 4 is controlled to descend so that the pressing part 3 presses the material. After maintaining the pressing time, the hydraulic cylinder 4 is controlled to rise and the pressed composite material is taken out. Through the above operation process, the multilayer composite equipment for manufacturing bio-based materials provided in this embodiment can efficiently and accurately complete the pressing of multilayer bio-based materials.

[0039] Based on Example 1, Example 2 made several optimizations and improvements to the multilayer composite equipment for manufacturing bio-based materials, aiming to further improve the performance and efficiency of the equipment.

[0040] Multiple positioning slots 21 are formed on the surface of the positioning seat 2 at the positions of the first material rack 6 and the second material rack 7. These positioning slots 21 are precisely designed to ensure that the first pull plate 62 and the second pull plate 72 can be inserted accurately, thereby improving the positioning accuracy and stability of the equipment. A baffle 22 is placed at the notch for further fixing and supporting the material. A positioning block 23 is installed on the bottom of the surface of the baffle 22. The stability and positional accuracy of the baffle 22 are ensured by the cooperation between the positioning block 23 and the positioning seat 2. Mounting bracket 1 31 and mounting bracket 2 32 are installed on the surface of the pressing part 3 for mounting the air push rod 52 and the short rack 81, respectively. This design makes the structure of the pressing part 3 more compact and facilitates installation and maintenance. In addition, a cavity is formed inside the pressing part 3, including an air inlet 33 and an air outlet 34, for the circulation of gas, further improving the dust removal and air curtain effect. One-way valve 2 57 and 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 unidirectional gas flow during inflation and deflation, preventing backflow and improving inflation efficiency and safety. Mounting seats 63 are installed at the ends of pull plates 62 and 72, with rotatable rollers 64 mounted on them. The rollers 64 contact the material; when the pull plates are inserted or removed, the rollers 64 roll, reducing frictional resistance with the material, making operation smoother and minimizing material damage.

[0041] Operating procedures

[0042] The bio-based material to be pressed is placed in the positioning seat 2 in sequence, and the pull plate 62 and pull plate 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 62 and pull plate 72 are reinserted into the positioning groove 21 of the positioning seat 2 to suspend the material. The heating element 9 is activated to heat and soften the material in the positioning seat 2. The air inflation element 5 is activated to fill the positioning seat 2 with gas through the air inlet pipe 55 to remove dust from the material and form an air curtain around it. The hydraulic cylinder 4 is controlled to descend so that the pressing part 3 presses the material. During the pressing process, the gas in the pressing section 3 is discharged through the air outlet 34, forming a circulating flow, which further improves the dust removal and air curtain effect. 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 multilayer composite equipment for manufacturing bio-based materials provided in Example 2 has significantly improved in terms of positioning accuracy, ease of operation, dust removal effect and safety, and can better meet the production needs of multilayer composites of bio-based materials.

[0043] A composite method for a multilayer composite device used in the manufacture of bio-based materials includes the following steps: a. Preparation stage: Place the workbench 1 in an appropriate position and ensure that all parts of the device are securely connected. Check the working status of key components such as the hydraulic cylinder 4, heating element 9, air inflation element 5, and drive element 8 to ensure there are no abnormalities. Prepare the bio-based materials to be composited and place them sequentially between the first shelf section 6 and the second shelf section 7 in the positioning seat 2, ensuring that each layer of material is separated by a gap. b. Material positioning and dust removal: Insert the material through the opening of the positioning seat 2, ensuring that the material is placed flat in the positioning seat 2. Activate the air inflation element 5 to extract gas and spray it into the positioning seat 2. Apply gas to the material through the air outlet 25. a. Dust removal and air curtain dust prevention: c. Material heating and softening: The heating element 9 is activated to heat and soften the material in the positioning seat 2 for subsequent pressing; d. Material rack movement and pressing: The hydraulic cylinder 4 begins to descend, and the pressing part 3 descends accordingly. At the same time, the drive element 8 starts to work, and through the linkage of the short rack 81, small gear plate 82, large gear plate 83 and large rack 84, the material rack part 1 6 and material rack part 2 7 are moved out of the positioning seat 2 to avoid interfering with the pressing. The pressing part 3 continues to descend to press the material in the positioning seat 2; e. Post-forming processing: After pressing is completed, the hydraulic cylinder 4 rises, and the pressing part 3 separates from the material; the composite material is taken out for subsequent processing or testing.
