Description

Technical Field

[0001] This utility model relates to the field of vibrating screens, specifically an epoxy molding compound vibrating screen with cooling and dust removal functions. Background Technology

[0002] Epoxy molding compound, also known as epoxy resin molding compound, is a powdered molding compound made of epoxy resin as the base resin and then adding high-performance phenolic resin, silica powder and other materials. After being processed by a molding machine, epoxy molding compound will have dust and debris on its surface and edges, making it unusable directly. Therefore, a vibrating screen is used.

[0003] According to publicly available patent 202322622447.X, an epoxy molding compound vibrating screen with cooling and dust removal functions includes a fixed base. Fixed blocks are provided on the front and rear ends of the bottom sides of the fixed base, and each fixed block has vertical mounting holes. Buffer springs are provided around the top of the fixed base, and a vibrating box is connected to the top of the buffer springs. An exciter is located at the center of the bottom of the vibrating box, and a feed inlet is located on the top left side of the vibrating box. The vibrating screen is positioned with the left side of the vibrating box being higher than the right side. In the process of realizing this utility model, the inventors discovered that at least the following problems remain unsolved in the prior art: after the epoxy molding compound completes the vibration treatment at the top of the vibrating screen, the electric telescopic rod opens the partition by extending and retracting. This allows the epoxy molding compound to be moved to the top of the cooling plate, where a fan can provide air cooling. The exhaust fan also effectively dissipates heat from the epoxy molding compound, solving the problem of heat accumulation inside the vibrating chamber. During operation, traditional epoxy molding compound vibrating screens generate a large amount of dust, which not only pollutes the working environment but also poses a potential health threat to operators. Traditional cooling and dust removal methods typically use motor-driven fan blades to generate airflow for cooling and dust removal from the epoxy molding compound. However, this method increases the complexity and cost of the equipment, and the maintenance and replacement of the motor during long-term operation is also a significant expense. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an epoxy molding compound vibrating screen with cooling and dust removal functions, so as to solve the technical problems of the current epoxy molding compound vibrating screen generating a large amount of dust and high equipment manufacturing and maintenance costs during the screening process.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: An epoxy molding compound vibrating screen with cooling and dust removal functions is designed, including a screen body and a base. Both the screen body and the base are fixedly installed with spring components via connecting plates. Two sets of limiting cylinders are fixedly connected to the base. The top of each limiting cylinder is connected to a limiting push rod via a cover plate. Air inlets are opened on both sides of the top of the cover plate. A piston is fixedly connected to one end of each limiting push rod. One side of the limiting cylinder is connected to an air supply pipe via an air storage cylinder. The other end of the air supply pipe is connected to a flexible air guide via a connecting pipe. The other end of the flexible air guide is connected to a high-pressure jet nozzle via an exhaust pipe. The bottom ends of the limiting cylinder and the air storage cylinder are connected via an air passage. A one-way valve is fixedly installed at one end of the air passage inside the air storage cylinder. A ball is installed inside the one-way valve body.

[0006] Preferably, one end of the cover plate is threaded to the inside of the top of the limiting cylinder, one end of the limiting push rod is fixedly connected to the bottom of the screen body, the other end of the limiting push rod is movably connected to the center of the cover plate and extends into the inside of the limiting cylinder, and the piston is slidably connected to the inside of the limiting cylinder.

[0007] Preferably, the gas storage cylinder is fixedly connected to one side of the outside of the limiting cylinder and is connected through a gas passage. One end of the gas supply pipe is sealed and connected to one side of the gas storage cylinder and communicates with its interior. The other end of the gas supply pipe is sealed and connected to one side of the connecting pipe and communicates with its interior. One end of the gas guide hose is sealed and connected to one end of the connecting pipe, and the other end of the gas guide hose is sealed and connected to one end of the exhaust pipe.

[0008] Preferably, the two ends of the exhaust pipe are fixedly connected between the two carrier plates, one end of the high-pressure jet head is sealed and connected to the inside of the exhaust pipe and communicates with the inside of the high-pressure jet head, and the other end of the high-pressure jet head is at a 60-degree angle to the carrier plate. There are two exhaust pipes, which are symmetrically installed on both sides of the inside of the screen body.

[0009] Preferably, the diameter of the ball is 4 / 5 of the inner diameter of the middle of the one-way valve, the inner diameter of the bottom of the one-way valve is 3 / 5 of the diameter of the ball, and the inner diameter of the top of the one-way valve is 2 / 5 of the diameter of the ball.

[0010] Preferably, a dust collection hood is fixedly connected to the top of the screen body, and a vacuum cleaner is connected to the top of the dust collection hood through a dust conveying pipe. The other end of the vacuum cleaner is connected to a dust storage box through a pipe.

[0011] Preferably, a sieve plate is fixedly connected to the upper surface of the carrier plate, and two sets of carrier plates are provided and symmetrically installed inside the sieve body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the vibrating screen vibrates, the bottom of the screen body drives the limiting push rod to move downward inside the limiting cylinder. At this time, the outside gas enters the inside of the limiting cylinder, and then the piston compresses the outside gas (there is a gap between the piston and the limiting cylinder, it is not in a sealed state), so that the compressed air enters the air passage. At this time, the air pressure pushes the ball from the bottom to the top of the one-way valve, so that the gas enters the gas storage pipe, and then the gas is transported to the inside of the connecting pipe through the gas delivery pipe, and then the gas is transported to the inside of the exhaust pipe through the connecting pipe and the gas guide hose. Finally, the gas is sprayed out by the high-pressure jet nozzle, thereby cooling the epoxy molding compound on the screen plate. This avoids the need to use a motor to drive the fan blades to generate air to cool the epoxy molding compound inside the vibrating screen, and reduces the cost of manufacturing and maintaining the vibrating screen.

[0014] The other end of the high-pressure jet head is at a 60-degree angle to the carrier plate. There are two exhaust pipes, which are symmetrically installed on both sides of the screen body. This allows the high-pressure jet heads on both sides of the screen body to blow air at an angle to the bottom of the screen plate, thereby generating gas convection. This allows the gas to flow quickly into the upper layer of the screen plate, thereby rapidly cooling the epoxy molding compound on the screen plate and blowing the dust attached to the epoxy molding compound into the screen body, which facilitates subsequent suction.

[0015] The diameter of the ball is 4 / 5 of the inner diameter of the middle of the check valve, the inner diameter of the bottom of the check valve is 3 / 5 of the diameter of the ball, and the inner diameter of the top of the check valve is 2 / 5 of the diameter of the ball. This allows the ball to move inside the check valve, thereby enabling the check valve to be blocked or opened, thus preventing gas from flowing back into the limit cylinder.

[0016] When the epoxy molding compound is being screened in the vibrating screen, the dust hood will draw away the dust and hot air floating in the screen body. Then, the vacuum cleaner will draw the hot air and dust in the dust hood into the dust storage box through the dust conveying pipe. This not only allows the hot air in the screen body to be discharged quickly, but also allows the floating dust to be drawn in and stored, which helps to improve the cooling and dust removal effect of the vibrating screen in the process of screening epoxy molding compound.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: An epoxy molding compound vibrating screen with cooling and dust removal functions, see [link to example]. Figures 1 to 7The system includes a screen body 1 and a base 11. Both the screen body 1 and the base 11 are fixedly mounted with spring components 13 via connecting plates 12. Two sets of limiting cylinders 2 are fixedly connected to the base 11. The top of each limiting cylinder 2 is connected to a limiting push rod 22 via a cover plate 21. One end of the cover plate 21 is threaded into the inside of the top of the limiting cylinder 2. One end of the limiting push rod 22 is fixedly connected to the bottom of the screen body 1, and the other end is movably connected to the center of the cover plate 21 and extends into the inside of the limiting cylinder 2. A piston 24 is slidably connected inside the limiting cylinder 2. Air inlets 23 are provided on both sides of the top of the cover plate 21. One end of the limiting cylinder 2 is fixedly connected to a piston 24. One side of the limiting cylinder 2 is connected to an air supply pipe 26 via an air storage cylinder 25. The other end of the air supply pipe 26 is connected to an air guide hose 28 via a connecting pipe 27. The other end of the air guide hose 28 is connected to a high-pressure jet head 3 via an exhaust pipe 29. The bottom ends of the limiting cylinder 2 and the air storage cylinder 25 are connected via an air passage 31. A one-way valve 32 is fixedly installed at one end of the air passage 31 inside the air storage cylinder 25. A ball 33 is installed inside the one-way valve 32. The air storage cylinder 25 is fixedly connected to one side of the limiting cylinder 2 outside and is connected via the air passage 31. One end of the air supply pipe 26... The end of the gas pipe 26 is sealed and connected to one side of the gas storage cylinder 25 and communicates with its interior. The other end of the gas delivery pipe 26 is sealed and connected to one side of the connecting pipe 27 and communicates with its interior. One end of the gas guide hose 28 is sealed and connected to one end of the connecting pipe 27, and the other end of the gas guide hose 28 is sealed and connected to one end of the exhaust pipe 29. When the vibrating screen vibrates, the bottom of the screen body 1 will drive the limiting push rod 22 to move downward inside the limiting cylinder 2. At this time, the outside gas will enter the inside of the limiting cylinder 2, and then the piston 24 will compress the outside gas (the piston 24 and the limiting cylinder 2 have a gap directly, not...). (In a sealed state), the compressed air enters the air passage 31. At this time, the air pressure pushes the ball 33 from the bottom to the top of the one-way valve 32, allowing the gas to enter the gas storage pipe. Then, the gas is transported to the inside of the connecting pipe 27 by the gas delivery pipe 26, and then the gas is transported to the inside of the exhaust pipe 29 by the connecting pipe 27 through the air guide hose 28. Finally, the gas is sprayed out by the high-pressure jet head 3, thereby cooling the epoxy molding compound on the screen plate 16. This avoids using a motor-driven fan blade to generate airflow to cool the epoxy molding compound inside the vibrating screen, reducing the cost of manufacturing and maintaining the vibrating screen.

[0030] For details, see Figure 3The two ends of the exhaust pipe 29 are fixedly connected between the two carrier plates 15. One end of the high-pressure jet head 3 is sealed and connected to the inside of the exhaust pipe 29 and communicates with it. The other end of the high-pressure jet head 3 is at a 60-degree angle to the carrier plate 15. There are two exhaust pipes 29, which are symmetrically installed on both sides inside the screen body 1. This allows the high-pressure jet heads 3 on both sides inside the screen body 1 to blow air at an angle to the bottom of the screen plate 16, thereby generating gas convection. This allows the gas to flow quickly into the upper layer of the screen plate 16, thereby rapidly cooling the epoxy molding compound on the screen plate 16 and blowing the dust attached to the epoxy molding compound into the inside of the screen body 1, which facilitates subsequent suction.

[0031] Further, see Figure 5 and Figure 6 The diameter of the ball 33 is 4 / 5 of the inner diameter of the middle of the one-way valve 32, the inner diameter of the bottom of the one-way valve 32 is 3 / 5 of the diameter of the ball 33, and the inner diameter of the top of the one-way valve 32 is 2 / 5 of the diameter of the ball 33. This allows the ball 33 to move inside the one-way valve 32, thereby enabling the one-way valve 32 to be blocked or opened.

[0032] It is worth noting that, see Figure 1 and Figure 2 A dust collection hood 4 is fixedly connected to the top of the screen body 1. A vacuum cleaner 42 is connected to the top of the dust collection hood 4 through a dust conveying pipe 41. The other end of the vacuum cleaner 42 is connected to a dust storage box 43 through a pipe. When the epoxy molding compound in the vibrating screen is being screened, the dust collection hood 4 will draw away the dust and hot air floating in the screen body 1. Then, the vacuum cleaner 42 will draw the hot air and dust in the dust collection hood 4 into the dust storage box 43 through the dust conveying pipe 41. This not only allows the hot air in the screen body 1 to be discharged quickly, but also allows the floating dust to be drawn and stored, which is beneficial to improving the cooling and dust removal effect of the vibrating screen in the process of screening epoxy molding compound.

[0033] It is worth noting that, see Figure 1 and Figure 7 A screen plate 16 is fixedly connected to the upper surface of the carrier plate 15. Two sets of carrier plates 15 are provided and symmetrically installed inside the screen body 1. Vibration motors 14 are fixedly connected to both sides of the outside of the screen body 1. When the epoxy molding compound enters the screen plate 16 inside the screen body 1, the vibration motor 14 will vibrate the entire screen body 1. At this time, the screen body 1 will vibrate on the base 11 through the spring member 13, thereby achieving the screening of the epoxy molding compound on the screen plate 16.
