Abstract
Description
Technical Field
[0001] The invention relates to the technical field of filter screen production, and in particular to an exhaust air compressor for filter screen injection molding. Background Art
[0002] When the filter is injection molded, an air compressor is often needed to extract the air inside the injection mold to ensure that the inside of the mold maintains a negative pressure state. For example, a piston air compressor proposed in the application number "CN202020534098.X" includes a piston air compressor body and a guide roller installed at a side position below the piston air compressor body. Handles are welded at both sides of the piston air compressor body, and a casing is fixedly connected to the front and rear walls of the piston air compressor body by screws. By utilizing the rod groove in the casing and the telescopic effect between the No. 1 rod block and the No. 2 rod block, a certain adjustment capability is possessed without occupying the working space. In addition, the rotating design of the connecting block, the handle and the No. 1 rod block and the anti-slip sleeve wrapped around the handle can effectively reduce the vibration of the personnel's hands when the bottom of the piston air compressor body is vibrated. Through the rotating parts provided between the connecting block and the disk block, when the personnel holds the handle on the side different from the connecting block, they can slightly lift it upwards, and the piston air compressor body can be deflected in a labor-saving manner using the disk block as the rotation point.
[0003] However, in the above technical solution, when the air compressor works for a long time, the piston will move for a long time inside the piston cavity and constantly rub against the inner wall, which will cause more heat to be generated between the piston cavity and the piston. The heat will continue to accumulate, and the accumulated heat will cause damage to the sealing ring on the piston, resulting in the equipment being unable to operate normally. Therefore, we propose an exhaust air compressor for filter injection molding to solve the above problems. Summary of the invention

DETAILED DESCRIPTION
[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0027] like Figures 1 to 7 As shown, an exhaust air compressor for filter screen injection molding comprises a storage box 1, wherein an air storage tank 101 and an oil storage tank 102 are respectively arranged at two ends inside the storage box 1, a transmission box 3 is installed at one end of the upper surface of the storage box 1, an exhaust pipe 4 is respectively installed at two ends of the upper surface of the transmission box 3, a heat dissipation mechanism 5 is installed between the exhaust pipe 4 and the oil storage tank 102, a transmission rod 10 is movably installed between the transmission box 3 and the exhaust pipe 4, a piston 9 is respectively installed at one end of the transmission rod 10 located inside the exhaust pipe 4, the piston 9 is respectively engaged and installed inside the exhaust pipe 4, a transmission frame 12 is respectively fixedly installed at the lower end of the transmission rod 10, and the transmission frame 12 is respectively movably installed inside the transmission box 3, a curved rotating rod 11 is movably installed inside the transmission box 3, and the rod body of the curved rotating rod 11 is respectively movably installed inside the transmission frame 12, a motor 8 is installed in the middle of the upper surface of the storage box 1, and the output end of the motor 8 is connected to the curved rotating rod 11.
[0028] like Figure 6 As shown, an air outlet pipe 6 and a drain pipe 7 are respectively installed at the upper and lower ends of the air storage tank 101, valves are respectively installed inside the air outlet pipe 6 and the drain pipe 7, and moving wheels 2 are respectively installed at both ends of the lower surface of the storage box 1.
[0029] The gas sucked inside the mold is compressed into the gas storage tank 101 for storage, and then when the gas inside the gas storage tank 101 needs to be discharged, it can be discharged through the gas outlet pipe 6;
[0030] Then, when the gas is compressed into the gas storage tank 101, the water vapor inside the gas will condense into water, and thus be retained inside the gas storage tank 101, so that the user can discharge the water flow through the drain pipe 7, thereby increasing the gas capacity inside the gas storage tank 101;
[0031] The moving wheels 2 are used to assist the user in moving the whole device, thereby improving its portability.
[0032] like Figure 6 and Figure 7 As shown, sealing rings 14 are respectively installed on the upper and lower ends of the outer side of the piston 9, and the sealing rings 14 are respectively fitted inside the exhaust pipe 4. An intake pipe 15 and a guide pipe 16 are respectively installed on the upper end of each exhaust pipe 4, and a one-way valve is respectively installed inside the intake pipe 15 and the guide pipe 16. The upper end of the interior of the air storage tank 101 is installed with a main pipe 13, and the upper end of the pipe body of the guide pipe 16 is respectively installed inside the main pipe 13.
[0033] The motor 8 drives the curved rotating rod 11 to rotate, and then the curved rotating rod 11 controls the transmission rod 10 to move up and down through the transmission frame 12. When the transmission rod 10 moves downward, negative pressure will gradually form between the upper end of the piston 9 and the upper end of the exhaust pipe 4, and then the positive pressure gas in the mold can push the one-way valve in the air inlet pipe 15 to open, so that the positive pressure gas in the mold can enter the exhaust pipe 4 along the air inlet pipe 15 to achieve the exhaust work in the mold, and then when the piston 9 moves upward, the piston 9 will cooperate with the exhaust pipe 4 to squeeze and pressurize the gas inside it, so that the pressurized gas opens the one-way valve inside the guide pipe 16, so that the pressurized gas enters the interior of the main pipe 13 along the guide pipe 16, and then enters the interior of the gas storage tank 101 along the main pipe 13 for storage, which is more convenient;
[0034] The sealing ring 14 is used to improve the sealing performance between the piston 9 and the air extraction pipe 4, thereby further improving the overall working efficiency.
[0035] like Figure 4 , Figure 5 and Figure 7As shown, the heat dissipation mechanism 5 includes a first connection box 501 and a second connection box 502. The first connection box 501 is fixedly installed at the front end of the storage box 1 and close to the side of the transmission box 3. The first connection box 501 is connected to the lower end of the interior of the oil storage tank 102. The second connection box 502 is fixedly installed at the rear end of the storage box 1 and close to the side of the transmission box 3. The second connection box 502 is connected to the upper end of the interior of the oil storage tank 102. The lower end of the interior of the first connection box 501 is connected with a liquid outlet pipe. 503, a liquid injection pipe 504 is installed through the rear side of the interior of the second connecting box 502, valves are installed inside the liquid outlet pipe 503 and the liquid injection pipe 504, the first connecting pipe 505 is installed through the front side of the upper end of the interior of the first connecting box 501 and the lower end of the interior of the exhaust pipe 4, the second connecting pipe 506 is installed through the rear side of the upper end of the interior of the second connecting box 502 and the lower end of the interior of the exhaust pipe 4, and one-way valves are installed on the upper ends of the first connecting pipe 505 and the second connecting pipe 506.
[0036] When the piston 9 moves upward, a negative pressure state is formed between the lower end of the piston 9 and the air extraction pipe 4. As the negative pressure increases, the lubricating oil inside the first connecting pipe 505 can push the one-way valve to open, allowing the lubricating oil to enter between the piston 9 and the air extraction pipe 4. The heat inside the air extraction pipe 4 is dissipated into the lubricating oil, and the inner wall of the air extraction pipe 4 is also lubricated, assisting the piston 9 and the sealing ring 14 to move up and down. Then, when the piston 9 moves downward, the piston 9 will squeeze the lubricating oil, and then the squeezed lubricating oil opens the one-way valve on the second connecting pipe 506 through pressure, allowing the lubricating oil to return to the inside of the oil storage tank 102 along the second connecting pipe 506, so that the piston 9 continuously moves up and down to allow the lubricating oil to flow between the piston 9 and the air extraction pipe 4, thereby achieving the heat dissipation and lubrication effect between the piston 9 and the air extraction pipe 4.
[0037] The working principle of this kind of air extraction compressor for filter screen injection molding:
[0038] When in use, first the motor 8 drives the curved rotating rod 11 to rotate, and then the curved rotating rod 11 controls the transmission rod 10 to move up and down through the transmission frame 12. When the transmission rod 10 moves downward, a negative pressure will gradually be formed between the upper end of the piston 9 and the upper end of the exhaust pipe 4, and then the positive-pressure gas in the mold can push the one-way valve in the air inlet pipe 15 to open, so that the positive-pressure gas in the mold can enter the exhaust pipe 4 along the air inlet pipe 15 to realize the exhaust work in the mold, and then when the piston 9 moves upward, the piston 9 will cooperate with the exhaust pipe 4 to squeeze and pressurize the gas inside it, so that the pressurized gas opens the one-way valve inside the guide pipe 16, so that the pressurized gas enters the interior of the main pipe 13 along the guide pipe 16, and then enters the interior of the gas storage tank 101 along the main pipe 13 for storage. When the piston 9 moves, a negative pressure state is formed between the lower end of the piston 9 and the air extraction pipe 4. As the negative pressure increases, the lubricating oil inside the first connecting pipe 505 can push the one-way valve to open, allowing the lubricating oil to enter between the piston 9 and the air extraction pipe 4. The heat inside the air extraction pipe 4 is dissipated into the lubricating oil, and the inner wall of the air extraction pipe 4 is also lubricated, assisting the piston 9 and the sealing ring 14 to move up and down. Then, when the piston 9 moves downward, the piston 9 will squeeze the lubricating oil, and then the squeezed lubricating oil opens the one-way valve on the second connecting pipe 506 through pressure, allowing the lubricating oil to return to the inside of the oil storage tank 102 along the second connecting pipe 506, so that the piston 9 continuously moves up and down to allow the lubricating oil to flow between the piston 9 and the air extraction pipe 4, thereby achieving the heat dissipation and lubrication effect between the piston 9 and the air extraction pipe 4.
[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
