Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a high-pressure pre-reduction mold for graphene oxide film. Background Technology

[0002] The high-temperature reduction of graphene oxide film involves stacking the film material sequentially in a reduction mold according to process requirements, then placing a stainless steel plate on top of the material, and finally stacking a weight on the stainless steel plate to flatten the material.

[0003] Because the material undergoes thickness changes during the reduction process, the upper weight may tilt or even flip, affecting the appearance of the reduced material and resulting in poor operational stability.

[0004] Meanwhile, the weight of the stacked objects during the operation needs to be tens or even hundreds of kilograms, and direct manual operation is labor-intensive and inconvenient. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a high-pressure pre-reduction mold for graphene oxide films that is highly stable and has a compact structure.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A high-pressure pre-reduction mold for graphene oxide film includes a frame, characterized in that it further includes a movable plate, a pressure plate, an elastic pre-tightening component, and an adjusting component. The frame has an internal cavity. The movable plate and the pressure plate are both connected within the frame, with the movable plate located above the pressure plate. The elastic pre-tightening component is located between the movable plate and the pressure plate, and under the action of the elastic pre-tightening component, the pressure plate tends to move downward. The adjusting component is located between the upper part of the frame and the movable plate, and under the action of the adjusting component, it can change the initial height position of the movable plate.

[0008] In the above-mentioned high-pressure pre-reduction mold for graphene oxide film, the frame includes a top plate, a bottom plate, and four columns. The bottom plate and the top plate are both rectangular, and the four columns are connected between the bottom plate and the top plate, forming a pressing cavity that matches the pressing plate between the top plate, the bottom plate, and the four columns.

[0009] In the aforementioned high-pressure pre-reduction mold for graphene oxide film, the column has an L-shaped cross-section, and the corner of the pressure plate is embedded in the L-shaped recess of the column.

[0010] In the aforementioned high-pressure pre-reduction mold for graphene oxide film, the movable plate matches the pressure plate, and the corner of the movable plate is embedded in the L-shaped recess of the column.

[0011] The elastic preload assembly includes a connecting rod and a spring. The lower end of the connecting rod is vertically fixed to the pressure plate. The movable plate has a through hole that is directly opposite the connecting rod. The spring is sleeved on the connecting rod, and the two ends of the spring act on the pressure plate and the movable plate, respectively.

[0012] In the above-mentioned high-pressure pre-reduction mold for graphene oxide film, the connecting rod, spring and corresponding clearance hole form a pre-tightening unit. The number of pre-tightening units is several, and the several pre-tightening units are evenly distributed between the pressure plate and the movable plate.

[0013] In the aforementioned high-pressure pre-reduction mold for graphene oxide film, the adjustment assembly includes an adjustment rod and an adjustment cylinder. The adjustment cylinder is fixedly connected to the top plate, and the adjustment rod passes through the adjustment cylinder and the two are threadedly connected. The lower end of the adjustment rod is axially fixed to the movable plate, and the adjustment rod can rotate relative to the movable plate.

[0014] In the high-pressure pre-reduction mold for graphene oxide film described above, the upper end of the adjusting rod has a connecting part for connecting with a tool.

[0015] In the above-mentioned high-pressure pre-reduction mold for graphene oxide film, the top plate and the column are detachably connected.

[0016] In the above-mentioned high-pressure pre-reduction mold for graphene oxide film, the top plate has a cylindrical connecting cylinder, the column has several positioning holes along its height direction, and also includes a pin, which can be simultaneously inserted and connected to the connecting cylinder and the positioning holes.

[0017] Compared with existing technologies, this high-pressure pre-reduction mold for graphene oxide film features a pressure plate that is constantly subjected to the elastic force of the elastic pre-tightening component. This ensures the pressure plate remains stably pressed against the stacked materials, guaranteeing proper processing. Because the movable plate is always acting on the pressure plate through the elastic pre-tightening component, the pressure plate maintains a consistent pressure on the stacked materials, preventing skewness during processing and resulting in high operational stability.

[0018] In addition, the initial height of the movable plate can be adjusted according to the actual situation. Therefore, this mold can be used for materials with different stacking heights, and its applicability is relatively high, making it highly practical. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, the high-pressure pre-reduction mold for graphene oxide film includes a frame 1, a movable plate 2, a pressure plate 3, an elastic pre-tightening component, and an adjusting component. The frame 1 has an internal cavity. The movable plate 2 and the pressure plate 3 are both connected inside the frame 1, with the movable plate 2 being the upper part of the pressure plate 3. The elastic pre-tightening component is located between the movable plate 2 and the pressure plate 3. Under the action of the elastic pre-tightening component, the pressure plate 3 tends to move downward. The adjusting component is located between the upper part of the frame 1 and the movable plate 2. Under the action of the adjusting component, the initial height position of the movable plate 2 can be changed.

[0026] The film-like material requiring reduction processing is stacked inside the frame 1, with the stacked material directly below the pressure plate 3. Initially, both the pressure plate 3 and the movable plate 2 are away from the stacked material.

[0027] After the materials are stacked and placed, the adjusting component moves the movable plate 2 and the pressure plate 3 downward together. After the pressure plate 3 comes into contact with the stacked materials, the adjusting component continues to move the movable plate 2 and the pressure plate 3 downward.

[0028] Under the action of the elastic preload spring, the pressure plate 3 is always under elastic pressure, ensuring that the pressure plate 3 always tends to press against the stacked materials. When the material is subjected to the reduction process, the pressure plate 3 will not tilt, and the pressure plate 3 will always press against the stacked materials, ultimately ensuring that the material is stably subjected to the reduction process.

[0029] The function of the adjustment component is to put the entire mold into and out of the working state. When out of the working state, it is convenient to stack the materials in the frame 1, and it is also convenient to remove the processed materials.

[0030] The frame 1 includes a top plate 1b, a bottom plate 1a, and four columns 1c. The bottom plate 1a and the top plate 1b are both rectangular. The four columns 1c are connected between the bottom plate 1a and the top plate 1b and form a pressing cavity that matches the pressing plate 3 between the top plate 1b, the bottom plate 1a, and the four columns 1c.

[0031] This structure saves on frame material consumption while ensuring that stacked materials can be easily placed inside the frame 1, and also ensures that the pressure plate 3 and the movable plate 2 can move smoothly up and down.

[0032] The column 1c has an L-shaped cross-section, and the corner of the pressure plate 3 is embedded in the L-shaped recess of the column 1c.

[0033] The movable plate 2 is matched with the pressure plate 3, and the corner of the movable plate 2 is embedded in the L-shaped notch of the column 1c.

[0034] The L-shaped column 1c serves as a guide for both the pressure plate 3 and the movable plate 2.

[0035] The elastic pretensioning assembly includes a connecting rod 4 and a spring 5. The lower end of the connecting rod 4 is vertically fixed to the pressure plate 3. The movable plate 2 has a through hole 2a that is directly opposite to the connecting rod 4. The spring 5 is sleeved on the connecting rod 4 and the two ends of the spring 5 act on the pressure plate 3 and the movable plate 2 respectively.

[0036] Link 4 positions the spring 5. Since the two ends of the spring 5 act on the pressure plate 3 and the movable plate 2 respectively, the pressure plate 3 always has a tendency to move downward to press the material.

[0037] It can be seen that there is no direct connection between the pressure plate 3 and the movable plate 2. When not in operation, the pressure plate 3 will fall to the bottom of the frame 1.

[0038] This reduces the load on spring 5. During operation, the operator can support the pressure plate 3 with their hands or tools. After the material is placed, the operator can remove their hands from the pressure plate 3 or take out the corresponding tools.

[0039] The aforementioned connecting rod 4, spring 5, and corresponding clearance hole 2a form a pre-tightening unit. The number of pre-tightening units is several, and the several pre-tightening units are evenly distributed between the pressure plate 3 and the movable plate 2.

[0040] The setting of multiple pre-tightening units can effectively improve the pre-tightening effect of the pressure plate 3 on the material.

[0041] The adjustment assembly includes an adjustment rod 6 and an adjustment cylinder 8. The adjustment cylinder 8 is fixedly connected to the top plate 1b, and the adjustment rod 6 passes through the adjustment cylinder 7 and the two are threadedly connected. The lower end of the adjustment rod 6 is axially fixed to the movable plate 2 and the adjustment rod 6 can rotate relative to the movable plate 2.

[0042] After the adjusting rod 6 is rotated, since the adjusting cylinder 7 does not rotate, the movable plate 2 will move up and down as the adjusting rod 6 rotates.

[0043] After the movable plate 2 acts on the pressure plate 3, the pressure plate 3 can eventually stably squeeze the stacked materials.

[0044] The upper end of the adjusting rod 6 has a connecting part 6a for connecting with a tool.

[0045] In this embodiment, the connecting part 6a at the upper end of the adjusting rod 6 is a prism-shaped structure, and the adjusting rod 6 can be easily rotated by a wrench.

[0046] Because the process requires a relatively long time, no corresponding handle or handwheel is provided on the adjusting rod 6. This is to prevent unauthorized personnel from accidentally operating the mold during the process.

[0047] The top plate 1b is detachably connected to the column.

[0048] This allows the initial position of the movable plate 2 to be changed, thus adapting to materials with different stacking heights.

[0049] The top plate 1b has a cylindrical connecting tube 8, and the column 1c has a number of positioning holes 1c1 along its height direction. It also includes a pin 9, which can be simultaneously inserted and connected to the connecting tube 8 and the positioning holes 1c1.

[0050] After the pin 9 is inserted into both the connecting cylinder 8 and the positioning hole 1c1, it can position and connect the top plate 1b to the upper part of the frame 1.

[0051] After the pin 8 is connected to different positioning holes 1c1, the initial height position of the top plate 1b can be changed accordingly.

[0052] Each column 1c has a corresponding connecting cylinder 8 and pin 9, which ensures that the top plate 1b is stably connected to the upper part of the frame 1. Of course, all the connecting cylinders 8 and pins 9 are at the same horizontal level.

[0053] This high-pressure pre-reduction mold for graphene oxide film ensures that the pressure plate is consistently subjected to the elastic force of the elastic pre-tightening component, allowing it to stably press against the stacked materials and guaranteeing proper processing. Because the movable plate is always acting on the pressure plate through the elastic pre-tightening component, the pressure plate maintains a consistent pressure on the stacked materials, preventing skewness during processing and resulting in high operational stability.

[0054] In addition, the initial height of the movable plate can be adjusted according to the actual situation. Therefore, this mold can be used for materials with different stacking heights, and its applicability is relatively high, making it highly practical.

[0055] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
