Therefore, we propose a new screening device for epoxy resin production to address these issues. Utility Model Content

[0006] The box body has a first screening chamber and a second screening chamber on its two sides, which are separated by a partition. The end of the box body corresponding to the first screening chamber has a first discharge port, and the end of the box body corresponding to the second screening chamber has a second discharge port. A screening cylinder is rotatably connected inside the box body, and the screening cylinder passes through the partition. A feed pipe is installed in the middle of one end of the box body corresponding to the first screening chamber.
[0007] The end of the feed pipe is rotatably connected to the screening cylinder and extends into it. The feed pipe is connected to a feeding hopper at one end on the outside of the box. The screening cylinder is driven to rotate by a drive mechanism. The screening cylinder has small screen holes on the circumferential side corresponding to the first screening chamber and large screen holes on the circumferential side corresponding to the second screening chamber. An air blowing mechanism for cleaning the small and large screen holes is provided above the box. A spiral feeding plate is installed on the inner wall of the screening cylinder.
[0008] Preferably, the vibration mechanism includes vibration springs, and vibration springs are installed at equal intervals between the base and the housing. Limiting posts are fixedly connected to the base and the housing at the positions corresponding to the vibration springs. Vibration motors are symmetrically installed on the bottom of both sides of the housing.
[0009] Preferably, the bottom of the inner sides of the first screening chamber and the second screening chamber are both inclined, and the bottoms of the first screening chamber and the second screening chamber are respectively inclined downwards towards the first discharge port and the second discharge port.
[0010] Preferably, the driving mechanism includes a drive motor, the drive motor is installed on the top of the housing corresponding to the second screening chamber, a first pulley is installed on the shaft end of the drive motor, and a second pulley is installed on the shaft end of the screening cylinder corresponding to the first pulley. The first pulley and the second pulley are connected by a transmission belt.
[0011] Preferably, the first pulley is connected to the second pulley via a transmission belt, and the outer diameter of the first pulley is smaller than the outer diameter of the second pulley.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention uses a drive mechanism to rotate a screening cylinder. Simultaneously, material enters the screening cylinder through a feeding hopper and feed pipe. As the cylinder rotates, a spiral feeding plate carries the material from the first screening chamber to the second screening chamber. A vibration mechanism causes the housing to vibrate, allowing small-diameter epoxy resin particles to fall through small sieve holes into the first screening chamber. Larger epoxy resin particles continue to move to a section of the screening cylinder in the second screening chamber, where they fall through large sieve holes. An air blowing mechanism cleans the small and large sieve holes, preventing blockage. This screening device allows for continuous screening of epoxy resin and automatic cleaning of the sieve holes, eliminating the need for machine downtime and effectively improving the efficiency of the screening device.
[0015] In this invention, the inner bottom of both the first and second screening chambers is inclined, and the bottoms of the first and second screening chambers are respectively inclined downwards towards the first and second discharge ports. When the material falls into the inner bottom of the first and second screening chambers after screening, the inclined inner bottoms of the first and second screening chambers cause the material to flow towards the first and second discharge ports respectively, so as to discharge the screened material into the inside of the box and avoid the material accumulating inside the box.
[0016] In this invention, when the screening cylinder rotates, the fan operates, causing outside air to pass through the filter element inside the filter box and then enter the air blowing pipe through the air inlet pipe. The air is then blown out through the air blowing hole, and the high-speed airflow impacts the material blocking the screen holes of the screening cylinder, which can clean the screen holes of the screening cylinder and prevent the screening cylinder from becoming blocked.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4This utility model provides a technical solution: a screening device for epoxy resin production, including a base 1, a box 2 disposed above the base 1, and the box 2 being driven to vibrate by a vibration mechanism.
[0024] The box body 2 has a first screening chamber 6 and a second screening chamber 7 respectively on both sides. The first screening chamber 6 and the second screening chamber 7 are separated by a partition 8. The box body 2 has a first discharge port 9 at the end corresponding to the first screening chamber 6 and a second discharge port 10 at the end corresponding to the second screening chamber 7. A screening cylinder 11 is rotatably connected inside the box body 2. The screening cylinder 11 passes through the interior of the partition 8. A feed pipe 12 is installed in the middle of one end of the box body 2 corresponding to the first screening chamber 6.
[0025] The end of the feed pipe 12 is rotatably connected to the screening cylinder 11 and extends into it. The feed pipe 12 is connected to the feeding hopper 13 at one end outside the box 2. The screening cylinder 11 is driven to rotate by the drive mechanism. The screening cylinder 11 has small screen holes 18 on the circumferential side corresponding to the first screening chamber 6 and large screen holes 19 on the circumferential side corresponding to the second screening chamber 7. An air blowing mechanism for cleaning the small screen holes 18 and large screen holes 19 is provided on the top of the box 2. A spiral feeding plate 25 is installed on the inner wall of the screening cylinder 11.
[0026] The screening cylinder 11 is driven to rotate by the drive mechanism. At the same time, the material enters the interior of the screening cylinder 11 through the feeding hopper 13 and the feed pipe 12. When the screening cylinder 11 rotates, the material is driven to flow from the first screening chamber 6 to the second screening chamber 7 by the spiral feeding plate 25. With the help of the vibration mechanism, the box 2 is vibrated, so that the small outer diameter epoxy resin particles fall into the first screening chamber 6 through the small screen hole 18. The large epoxy resin particles after screening continue to move to the section of the screening cylinder 11 in the second screening chamber 7, and then fall into the second screening chamber 7 through the large screen hole 19. With the help of the air blowing mechanism, the particles blocked in the small screen hole 18 and the large screen hole 19 of the screening cylinder 11 can be cleaned, so as to avoid the material blocking the small screen hole 18 and the large screen hole 19. Through this screening device, epoxy resin can be screened in a continuous flow, and the screen holes can be cleaned automatically, avoiding the need to stop the machine to clean the screen holes, which effectively improves the working efficiency of the screening device.
[0027] Please see Figures 1 to 4 The vibration mechanism includes a vibration spring 3. Vibration springs 3 are installed at equal intervals between the base 1 and the box 2. Limiting posts 4 are fixedly connected to the base 1 and the box 2 at the positions corresponding to the vibration springs 3. Vibration motors 5 are symmetrically installed on the bottom of both sides of the box 2. When the vibration motors 5 work, they drive the box 2 to vibrate. The box 2 is connected to the base 1 through the vibration springs 3, thereby enabling the box 2 to generate high-frequency automatic vibration to assist the screening cylinder 11 in screening materials.
[0028] Please see Figures 1 to 4 The bottom inner sides of the first screening chamber 6 and the second screening chamber 7 are both inclined, and the bottoms of the first screening chamber 6 and the second screening chamber 7 are inclined downwards towards the first discharge port 9 and the second discharge port 10, respectively. When the material falls into the bottom inner side of the first screening chamber 6 and the second screening chamber 7 after screening, the inclined bottom inner sides of the first screening chamber 6 and the second screening chamber 7 cause the material to flow towards the first discharge port 9 and the second discharge port 10, respectively, so as to discharge the screened material into the inside of the box 2 and avoid the material from accumulating inside the box 2.
[0029] Please see Figures 1 to 4 The drive mechanism includes a drive motor 14. The drive motor 14 is installed on the top of the housing 2 corresponding to the second screening chamber 7. A first pulley 15 is installed on the shaft end of the drive motor 14. A second pulley 16 is installed on the shaft end of the screening cylinder 11 corresponding to the first pulley 15. The first pulley 15 and the second pulley 16 are connected by a transmission belt 17. The first pulley 15 and the second pulley 16 are connected by a transmission belt 17. The outer diameter of the first pulley 15 is smaller than the outer diameter of the second pulley 16. When the drive motor 14 is working, it drives the first pulley 15 to rotate. The first pulley 15 drives the second pulley 16 to rotate through the transmission belt 17, so that the second pulley 16 drives the screening cylinder 11 to rotate. With the help of the spiral feeding plate 25 set on the inner wall of the screening cylinder 11, the material is driven to flow. At the same time, the rotation of the screening cylinder 11, in conjunction with the air blowing mechanism, can clean the screen holes of the screening cylinder 11 in sequence.
[0030] Please see Figures 1 to 4 The air blowing mechanism includes an air blowing pipe 20. The air blowing pipe 20 is installed on the top inner side of the box 2 and passes through the interior of the partition 8. A filter box 21 is installed near the middle of the box 2. A fan 22 is installed on the top of the box 2 near the filter box 21. The fan 22 is connected to the filter box 21 and is connected to the air blowing pipe 20 through the air inlet pipe 23. Air blowing holes 24 are equidistantly opened at the bottom of the air blowing pipe 20. When the screening cylinder 11 rotates, the fan 22 works to make the outside air pass through the filter element in the filter box 21 and then enter the interior of the air blowing pipe 20 through the air inlet pipe 23. Then the air is blown out through the air blowing holes 24. The high-speed airflow impacts the material blocked in the screen holes of the screening cylinder 11, which can clean the screen holes of the screening cylinder 11 and prevent the screening cylinder 11 from becoming blocked.
[0031] Working Principle: This epoxy resin production screening device uses a drive mechanism to rotate the screening cylinder 11. Simultaneously, material enters the screening cylinder 11 through the feeding hopper 13 and the feed pipe 12. As the screening cylinder 11 rotates, the spiral feeding plate 25 drives the material to flow from the first screening chamber 6 to the second screening chamber 7. A vibration mechanism causes the housing 2 to vibrate, allowing small-diameter epoxy resin particles to fall through the small screen holes 18 into the first screening chamber 6. Larger epoxy resin particles continue to move to a section of the screening cylinder 11 in the second screening chamber 7, then fall through the large screen holes 19 into the second screening chamber 7. An air blowing mechanism cleans the particles blocking the small and large screen holes 18 and 19 of the screening cylinder 11, preventing material blockage. This screening device allows for continuous screening of epoxy resin and automatic cleaning of the screen holes, avoiding downtime for cleaning and effectively improving the working efficiency of the screening device.
[0032] When the vibrating motor 5 is working, it drives the housing 2 to vibrate. The housing 2 is connected to the base 1 by the vibrating spring 3, which enables the housing 2 to generate high-frequency automatic vibration to assist the screening cylinder 11 in screening the material. When the material falls into the inner bottom of the first screening chamber 6 and the second screening chamber 7 after screening, the inclined inner bottom of the first screening chamber 6 and the second screening chamber 7 causes the material to flow towards the first discharge port 9 and the second discharge port 10 respectively, so as to discharge the screened material into the interior of the housing 2 and avoid the material from accumulating inside the housing 2.
[0033] When the drive motor 14 is working, it drives the first pulley 15 to rotate. The first pulley 15 drives the second pulley 16 to rotate through the transmission belt 17, which in turn drives the screening cylinder 11 to rotate. This, in conjunction with the spiral feeding plate 25 installed on the inner wall of the screening cylinder 11, facilitates the flow of materials. Simultaneously, the rotation of the screening cylinder 11, in conjunction with the air blowing mechanism, cleans the screen holes of the screening cylinder 11 in sequence. When the screening cylinder 11 rotates, the blower 22 operates, causing outside air to pass through the filter element in the filter box 21 and then enter the air blowing pipe 20 through the air inlet pipe 23. The air is then blown out through the air blowing hole 24, and the high-speed airflow impacts the material blocking the screen holes of the screening cylinder 11, thus cleaning the screen holes and preventing blockage of the screening cylinder 11.
