Description

Technical Field

[0001] The present invention relates to the technical field of mica plate production, and specifically relates to a continuous pressing device for mica plate production. Background Art

[0002] Mica plate is a high-quality insulating material, which has the advantages of being non-toxic, odorless, high-temperature resistant, high-voltage resistant, aging resistant, corrosion resistant, and stable electrical performance. Especially its excellent high-temperature insulation performance, with a maximum temperature resistance of up to 1000 °C. Among high-temperature insulating materials, it has good cost performance, so it is widely used in fields such as household appliances, metallurgy, and chemical industry.

[0003] Traditional mica plates are made by bonding and pressing mica substrates and mica papers with organic silicone glue. During the pressing process, a part of the organic silicone glue between the mica substrate and the mica paper will be extruded and overflow from the side of the mica substrate due to pressure. After these overflowed organic silicone glues solidify, a part scatters on the workbench, and another part adheres to the side of the mica plate. Workers need to clean the organic silicone glue adhering to the side of the mica plate and the organic silicone glue falling on the surface of the workbench later, which is time-consuming and laborious, affecting the production efficiency of mica plates. At the same time, when the organic silicone glue is heated during pressing, a large amount of toxic and harmful gases will be generated, and this gas will cause harm to the human body to a certain extent. Therefore, a continuous pressing device for mica plate production is proposed. Summary of the Invention

[0013] In summary, the present invention mainly has the following beneficial effects: 1.

By designing the air suction component, when the moving frame and the square scraping plate move downward, the piston rod and the piston are driven to move towards the top of the inner cavity of the piston cylinder in cooperation with the gear-rack structure. At this time, negative pressure is generated in the piston cylinder, and suction force is generated at the suction port, sucking the toxic gas inside the storage groove and the solidified glue debris falling at the bottom of the storage groove into the first connecting pipe together. The toxic gas enters the piston cylinder, and the glue debris is collected by the collection component. Until the piston rod drives the piston to move towards the bottom of the piston cylinder, the toxic gas inside is discharged to the filtering component through the second connecting pipe. The air suction component is used to centrally collect the toxic gas, and the sealing gasket and the sealing strip are used to ensure that the toxic gas does not escape outward during the generation process, preventing it from being inhaled by the staff and protecting the physical health of the staff; 3. By designing the collection component, after the toxic gas and the solidified glue debris falling at the bottom of the storage groove are sucked into the first connecting pipe together, the toxic gas passes through the filter screen and enters the piston cylinder, while the solidified glue debris is blocked by the filter screen and enters the collection box through the material guiding block and the material discharging channel. After a period of time, the staff opens the sealing door and centrally processes the collected glue debris, greatly improving the cleaning speed of the staff for the glue debris and further improving the production rate of the mica plate.

Specific implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0017] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0018] A continuous pressing device for mica plate production, as Figure 1-11As shown in the figure, it includes a base body 100. Support columns 110 are fixedly installed at the four corners of the top of the base body 100. The tops of the four support columns 110 are fixedly installed with the same top plate 120. A hydraulic push rod 130 is fixedly installed on the upper surface of the top plate 120. The telescopic end of the hydraulic push rod 130 penetrates and extends below the top plate 120 and is fixedly connected with an upper fixing seat 140. Guide blocks 141 are fixedly installed at both ends of the upper fixing seat 140. First guide rods 142 are fixedly installed at both ends of the upper surface of the base body 100. The two groups of guide blocks 141 are respectively slidably connected with the corresponding first guide rods 142. A lower fixing seat 150 is fixedly installed at the center of the top of the base body 100. Pressing plates 160 are fixedly installed on the opposite sides of the upper fixing seat 140 and the lower fixing seat 150. Heating tubes 161 are installed inside the pressing plates 160. A workpiece to be pressed 170 is placed on the top of the pressing plate 160 on the lower fixing seat 150. A partition plate 180 is fixedly installed horizontally inside the base body 100. A scraping assembly 200 is arranged inside the lower fixing seat 150. An air suction assembly 300 is installed in the chamber above the partition plate 180 inside the base body 100. A filtering assembly 400 is installed in the chamber below the partition plate 180 inside the base body 100; The scraping assembly 200 includes two groups of electric push rods 210 fixedly installed on the upper surface of the partition plate 180 and symmetrically arranged at an oblique angle. The output ends of the two groups of electric push rods 210 are fixedly connected with connecting blocks 220. Connecting columns 230 are fixedly connected to the centers of the upper surfaces of the two groups of connecting blocks 220. The tops of the two groups of connecting columns 230 penetrate and extend into the lower fixing seat 150 and are fixedly connected with the same moving frame 240. A storage groove 250 matching the moving frame 240 is formed inside the lower fixing seat 150. The moving frame 240 is slidably connected with the storage groove 250. A square scraping plate 241 is fixedly installed on the inner side of the upper end of the moving frame 240. The square scraping plate 241 is attached to the side surface of the pressing plate 160.

[0019] Place the workpiece 170 to be pressed on the pressing plate 160 on the lower fixing seat 150, and then start the hydraulic push rod 130. The telescopic end of the hydraulic push rod 130 pushes the upper fixing seat 140 and the pressing plate 160 fixed at the bottom to move downward to press and form the workpiece 170 to be pressed. Since the heating tube 161 is arranged inside the pressing plate 160, it can ensure the pressing effect on the workpiece 170 to be pressed. At the same time, during the pressing process, part of the silicone glue between the mica substrate and the mica paper is extruded and overflows from the four sides of the workpiece 170 to be pressed. After high-temperature solidification, part of the glue adheres to the four sides of the workpiece 170 to be pressed and the two groups of pressing plates 160, and the other part drops into the storage groove 250. At this time, start the two groups of electric push rods 210. The telescopic ends of the electric push rods 210 drive the connecting block 220 and the connecting column 230 to move downward, thereby driving the moving frame 240 and the square scraper 241 to move downward to scrape and clean the glue adhering to the four sides of the workpiece 170 to be pressed and the two groups of pressing plates 160, so that it drops into the storage groove 250. It should be noted that the square scraper 241 at the upper end of the moving frame 240 will move to the outside of the upper fixing seat 140 when the workpiece 170 to be pressed is heated during pressing. By setting the scraping assembly 200, the overflowing glue is cleaned up when the workpiece 170 to be pressed is pressed and formed, without the need for subsequent workers to clean it twice, improving the production efficiency of the mica plate. At the same time, these extruded glues are collected centrally to prevent them from scattering on the four sides of the lower fixing seat 150 and affecting subsequent operations.

[0020] Please refer particularly to Figure 1 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, the air intake assembly 300 includes an L-shaped connecting rod 310 fixedly connected to one side of two groups of connecting blocks 220. A first rack 320 is fixedly installed on one side of the L-shaped connecting rod 310. A gear 330 is meshed with one side of the first rack 320. The gear 330 is connected to one side of the inner cavity of the base body 100 through a rotating shaft 340. The rotating shaft 340 is connected to one side of the inner cavity of the base body 100 through a bearing. A second rack 350 is meshed with the other end of the gear 330. A special-shaped connecting rod 360 is fixedly connected to the rear side of the second rack 350. The other end of the special-shaped connecting rod 360 is fixedly connected to a fixed block 380. A piston rod 390 is fixedly connected to the bottom end of the fixed block 380. A piston 3910 is fixedly installed at the bottom end of the piston rod 390. A piston cylinder 3920 is sleeved outside the piston 3910. The piston cylinder 3920 is fixedly installed at the center of the upper surface of the partition plate 180. A first connecting pipe 3930 is fixedly connected to the bottom end outside the piston cylinder 3920. The other end of the first connecting pipe 3930 penetrates through the base body 100 and the lower fixing seat 150 and extends to the bottom of the inner cavity of the storage groove 250. A second connecting pipe 3960 is fixedly connected to the bottom of the piston cylinder 3920. The second connecting pipe 3960 penetrates and extends below the partition plate 180. There are four groups of the first connecting pipes 3930 in total. And a suction port 3940 is fixedly installed at one end of each group of the first connecting pipes 3930 located in the storage groove 250. Check valves are fixedly installed inside one end of the second connecting pipe 3960 and the four groups of the first connecting pipes 3930. A collection assembly 3950 is installed on each group of the first connecting pipes 3930.

[0021] When the moving frame 240 and the square scraping plate 241 move downward, the connecting block 220 drives the L-shaped connecting rod 310 and the first rack 320 to move downward synchronously, thereby driving the gear 330 meshed with the first rack 320 to start rotating, thereby driving the second rack 350 meshed with the other end of the gear 330 to move upward, further driving the special-shaped connecting rod 360 to move upward, thereby driving the fixed block 380 to move upward, thereby driving the piston rod 390 and the piston 3910 to start moving toward the top of the inner cavity of the piston cylinder 3920. At this time, a negative pressure is generated inside the piston cylinder 3920, and a suction force is generated at the suction port 3940, sucking the toxic gas inside the storage groove 250 and the solidified glue debris falling on the bottom of the storage groove 250 into the first connecting pipe 3930 together. And the toxic gas is the toxic and harmful gas generated when pressing and heating the workpiece to be pressed 170, and is enclosed in the closed space of the storage groove 250 together. The toxic gas enters the piston cylinder 3920 through the first connecting pipe 3930. Until when the piston rod 390 drives the piston 3910 to move toward the bottom of the piston cylinder 3920, the toxic gas inside is discharged to the filtering assembly 400 through the second connecting pipe 3960. The generated toxic gas is centrally collected through the air intake assembly 300, and does not escape outward during the generation process of the toxic gas, preventing it from being inhaled by the staff and protecting the health of the staff.

[0022] Please refer to Figure 1 , Figure 8 as well as Figure 11 As shown, the collecting assembly 3950 includes a fixed box 3951 installed on the outer wall of the first connecting tube 3930, the fixed box 3951 is connected to the inside of the first connecting tube 3930, a filter screen 3952 is fixedly installed on one side of the fixed box 3951, guide blocks 3953 are fixedly installed at both ends of the bottom of the fixed box 3951, a material discharge channel 3954 is fixedly connected to the bottom of the fixed box 3951, a collecting box 3955 is fixedly connected to the bottom end of the material discharge channel 3954, the bottom of the collecting box 3955 is fixedly connected to one side of the base body 100 through a fixed bottom plate 3957, and a sealing door 3956 is installed on one side of the collecting box 3955.

[0023] After being sucked into the first connecting pipe 3930 together with the toxic gas and the solidified glue fragments that fell at the bottom of the storage groove 250, the toxic gas passes through the filter screen 3952 and enters the piston cylinder 3920, while the solidified glue fragments are blocked by the filter screen 3952 and enter the collection box 3955 through the guide block 3953 and the discharge channel 3954. After a period of time, the staff opens the sealing door 3956 and collects the glue fragments for centralized treatment.

[0024] Please refer to Figure 2 , Figure 4 as well as Figure 5 As shown, a sealing gasket 3970 is fixedly installed on the top of the movable frame 240, and a sealing groove is opened on the sealing gasket 3970. The bottom of the upper fixed seat 140 is located on the four sides of the pressing plate 160 and is fixedly installed with sealing strips 3980 matching the sealing groove.

[0025] When the pressing plate 160 on the upper fixed seat 140 is in contact with the upper surface of the workpiece 170 to be pressed, the sealing strip 3980 is embedded in the sealing groove on the sealing gasket 3970 to complete the sealing of the top of the storage groove 250, so that the generated toxic gas will not escape to the outside. It will be cleaned up later in conjunction with the suction component 300, further ensuring the health of the staff.

[0026] Please refer to Figure 1 , Figure 2 as well as Figure 7 As shown, the filter assembly 400 includes a fixed frame 410 fixedly installed on the inner walls on both sides of the chamber below the partition 180 in the base body 100, and multiple groups of activated carbon filter layers 420 are arranged between the two groups of fixed frames 410, and several groups of activated carbon filter layers 420 are slidably connected to the fixed frame 410, and one end of several groups of activated carbon filter layers 420 is fixedly connected to the same mounting plate 430, the mounting plate 430 extends to the outside of the base body 100 and is fixedly installed with a handle 440, and the bottom end of the base body 100 away from the handle 440 is fixedly connected to an exhaust pipe.

[0027] After the toxic gas passes through multiple groups of activated carbon filter layers 420 and is purified into a non-toxic gas, it is discharged through the exhaust pipe. When it is necessary to replace the activated carbon filter layer 420, first release the fixation between the mounting plate 430 and the base body 100, and then pull the handle 440 to extract the activated carbon filter layer 420 to complete its replacement, and its replacement is relatively convenient and simple.

[0028] Please refer specifically to Figure 8 As shown, second guide rods 370 are longitudinally sleeved on both the L-shaped connecting rod 310 and the special-shaped connecting rod 360. The second guide rods 370 are fixedly installed between the upper surface of the partition plate 180 and the top of the inner cavity of the base body 100, and the L-shaped connecting rod 310 and the special-shaped connecting rod 360 are respectively slidably connected to the corresponding second guide rods 370.

[0029] By setting the second guide rods 370, the up-and-down movement of the L-shaped connecting rod 310 and the special-shaped connecting rod 360 is made more stable, further improving the stability of the operation of the device.

[0030] During use, place the workpiece 170 to be pressed on the pressing plate 160 on the lower fixing seat 150, and then start the hydraulic push rod 130. The telescopic end of the hydraulic push rod 130 pushes the upper fixing seat 140 and the pressing plate 160 fixed at the bottom to move downward to press and form the workpiece 170 to be pressed. Since the heating tube 161 is arranged inside the pressing plate 160, it can ensure the pressing effect on the workpiece 170 to be pressed. At the same time, during the pressing process, part of the silicone glue between the mica substrate and the mica paper is extruded and overflows from the four sides of the workpiece 170 to be pressed. After high-temperature solidification, part of the glue adheres to the four sides of the workpiece 170 to be pressed and the two pressing plates 160, and the other part drops into the storage groove 250. At this time, start the two electric push rods 210. The telescopic ends of the electric push rods 210 drive the connecting block 220 and the connecting column 230 to move downward, thereby driving the moving frame 240 and the square scraper 241 to move downward to scrape and clean the glue adhering to the four sides of the workpiece 170 to be pressed and the two pressing plates 160, so that it drops into the storage groove 250. By setting the scraping assembly 200, the overflowing glue is cleaned up when the workpiece 170 to be pressed is pressed and formed, without the need for subsequent workers to clean it up again, improving the production efficiency of the mica plate. At the same time, these extruded glues are collected centrally to prevent them from scattering around the lower fixing seat 150 and affecting subsequent operations; when the moving frame 240 and the square scraper 241 move downward, the connecting block 220 drives the L-shaped connecting rod 310 and the first rack 320 to move downward synchronously, thereby driving the gear 330 engaged with the first rack 320 to start rotating, thereby driving the second rack 350 engaged with the other end of the gear 330 to move upward, and further driving the special-shaped connecting rod 360 to move upward, thereby driving the fixed block 380 to move upward, thereby driving the piston rod 390 and the piston 3910 to move toward the top of the inner cavity of the piston cylinder 3920. At this time, negative pressure is generated in the piston cylinder 3920, and suction is generated at the suction port 3940 to suck the toxic gas inside the storage groove 250 and the solidified glue debris falling at the bottom of the storage groove 250 into the first connecting pipe 3930. The toxic gas is the toxic and harmful gas generated when the workpiece 170 to be pressed is pressed and heated, and is enclosed in the closed space of the storage groove 250. The toxic gas enters the piston cylinder 3920 through the first connecting pipe 3930 until the piston rod 390 drives the piston 3910 to move toward the bottom of the piston cylinder 3920, and the internal toxic gas is discharged to the filtering assembly 400 through the second connecting pipe 3960. The generated toxic gas is centrally collected by the suction assembly 300, and does not escape outward during the generation of the toxic gas, preventing it from being inhaled by the staff and protecting the health of the staff. The parts not involved in this device are the same as or can be implemented by the prior art.
