Description

Technical Field

[0001] This utility model relates to the field of dust recovery technology, specifically a dust recovery device for an epoxy molding compound production line. Background Technology

[0002] In industrial plastic molding, the main raw materials include powders, granules, solutions, and dispersions. Some molding processes utilize monomers and prepolymers, with powders and granules being the most widely used. Powders are made by uniformly mixing and dispersing powdered resin with various additives. Granules are mixed granular materials produced by further plasticizing powders through plasticizing processes and using different methods. Granules reduce the requirements of the molding process during processing, making molding easier. However, dust recovery is necessary in the production of epoxy molding compounds for semiconductor devices. With advancements in production technology and equipment, many product processes now directly use powder processing, eliminating the granulation step and reducing production costs.

[0003] When processing powder materials, workers need to put the powder into a dispersing vessel for dispersion and mixing, then convey it to a weighing device for weighing, and finally send it to an extruder for extrusion. During the powder feeding process, a large amount of powder is released into the air, which pollutes the workshop air environment and wastes raw materials. Most workshops are equipped with bag filters to recover and reuse the dust, but workers need to periodically collect the powder from the dust collection bags of the bag filters for reuse, which is cumbersome and needs improvement.

[0004] As disclosed in CN210229447U, a dust recovery device for a plastic particle production line can collect the dust generated during feeding. The dust is then drawn away by a fan and sent to a dust separator. After the filter cloth discharges the air, the dust can be reused. The dust filter can assist in the exhaust of the powder hopper and the filtration of dust, which can prevent dust from spreading in the workshop, improve the production environment of the workshop, protect the respiratory health of workers, reduce raw material waste, and save costs.

[0005] However, the device cannot clean the dust filter during use, which causes the dust filter to become clogged and affects the quality of dust recovery.

[0006] Therefore, we urgently need to provide a dust recovery device for epoxy molding compound production lines. Utility Model Content

[0022] Example 1: Current technology cannot clean dust filters during use, leading to filter clogging and affecting dust recovery quality. Please refer to [link / reference needed]. Figures 1-4 This embodiment provides a dust recovery device for an epoxy molding compound production line, which can clean the filter cartridge, prevent filter cartridge clogging, and improve the quality and efficiency of dust recovery. The dust recovery device for the epoxy molding compound production line includes a processing box 1, an exhaust fan 2, a filter cartridge 3, an exhaust pipe 4, an exhaust hood 5, and a collection box 9.

[0024] The cleaning mechanism includes a motor 601, a rotating shaft 602, a bevel gear 603, a connecting rod 604, a bevel gear 605, a scraper 606, a threaded rod 607, a limiting rod 608, a scraper 609, a pulley 610, a belt 611, and a guide pipe 612. The motor 601 is fixedly installed on the top back of the processing box 1. The motor 601 is model R-31ZY and has forward and reverse rotation functions. The rotating shaft 602 is fixedly installed at the output end of the motor 601. The bevel gear 603 is fixedly installed on the outer side of the front of the rotating shaft 602. The bevel gear 603 meshes with the bevel gear 605. The threaded rod 607 has external threads, and the scraper 609 is threadedly connected to the outside of the threaded rod 607. When cleaning the filter cylinder 3 is required, the motor 601 is started to drive the rotating shaft 602 and the bevel gear 603 to rotate. The bevel gear 603 meshes with the bevel gear 605, thereby causing the connecting rod 604 to drive the scraper 606 to rotate and clean the inner wall of the filter cylinder 3. At the same time, with the transmission of the pulley 610 and the belt 611, the threaded rod 607 rotates and connects with the scraper 609, causing the scraper 609 to move up and down along the limiting rod 608 to clean the outer wall of the filter cylinder 3, thus achieving cleaning. The cleaning of filter cartridge 3 prevents clogging and improves dust recovery quality and efficiency. Connecting rod 604 is rotatably connected to the inside of processing box 1, with its lower end extending into the inside of filter cartridge 3.

The connecting rod 604 has a hollow structure. The connecting pipe 702 is rotatably connected to the connecting rod 604. When the connecting rod 604 drives the scraper 606 to rotate and clean the inner wall of the filter cartridge 3, the air blowing head 703 blows air into the filter cartridge 3 to blow out the impurities adhering to the pores of the filter cartridge 3, thereby improving the cleaning quality of the filter cartridge 3. The air blowing head 703 is connected to the outside of the connecting rod 604.

[0026] Example 2: Based on Example 1, please refer to Figures 1-4 To achieve angle adjustment of the exhaust duct 4 and improve the flexibility of dust recovery, this device is also equipped with an adjustment mechanism. The adjustment mechanism includes a second motor 801, an output shaft 802, a first gear 803, and a second gear 804. The second motor 801 is fixedly installed on the upper left side of the processing box 1.

The output shaft 802 is fixedly installed at the output end of the second motor 801. The first gear 803 is fixedly installed on the outer side of the upper end of the output shaft 802. The second gear 804 is fixedly installed on the outer side of the exhaust duct 4. The first gear 803 and the second gear 804 mesh with each other. The exhaust duct 4 is rotatably connected to the processing box 1. By starting the second motor 801, the output shaft 802 is driven to rotate, which, in conjunction with the meshing of the first gear 803 and the second gear 804, causes the exhaust duct 4 to rotate, thereby achieving angle adjustment of the exhaust duct 4 and improving the flexibility of dust recovery.

[0027] During use, in the epoxy molding compound production process, when dust absorption is required, the exhaust fan 2 is started to create negative pressure inside the treatment box 1 and the exhaust pipe 4. Under the action of negative pressure, the dust generated during epoxy molding compound production is drawn through the exhaust hood 5 into the filter cartridge 3 via the exhaust pipe 4. The filter cartridge 3 forces air through it and out through the exhaust port of the exhaust fan 2. The dust falls into the collection box 9 under gravity. When cleaning of the filter cartridge 3 is required, the motor 601 is started to drive the rotating shaft 602 and the bevel gear 603 to rotate. The bevel gear 603 meshes with the bevel gear 605, thereby... The connecting rod 604 drives the scraper 606 to rotate and clean the inner wall of the filter cylinder 3. At the same time, with the transmission of the pulley 610 and belt 611, the threaded rod 607 rotates and is threadedly connected to the scraper 609. The scraper 609 moves up and down along the limit rod 608 to clean the outer wall of the filter cylinder 3. During the process of the connecting rod 604 driving the scraper 606 to rotate and clean the inner wall of the filter cylinder 3, the air pump 701 is started, so that high-pressure gas is blown out through the air blower 703 through the connecting pipe 702 to blow air into the inside of the filter cylinder 3, blowing out the impurities adhering to the pores of the filter cylinder 3, thereby improving the cleaning quality of the filter cylinder 3.
