Description

Technical Field

[0001] This utility model relates to the field of dust collection and purification for milling machines, and in particular to a dust collection and purification device for PCB milling machines. Background Technology

[0002] With the rapid development of the electronics industry, the dust problem generated during the production process of PCB (printed circuit board) milling machines has become increasingly prominent. This dust mainly consists of micron-sized metal particles and resin debris, which not only pollutes the environment but may also harm human health. Currently, traditional bag or cartridge dust collectors have significant limitations in handling this type of dust.

[0003] On the one hand, micron-sized metal dust and resin debris have small particle sizes, making it difficult for traditional bag or cartridge dust collectors to efficiently separate these fine particles. This leads to easy clogging of the filter media surface, reducing dust removal efficiency and increasing equipment maintenance costs. On the other hand, these metal dust particles contain many valuable metal components, but existing equipment cannot effectively recover them, resulting in resource waste.

[0004] Therefore, there is an urgent need for a dust collection and purification device for PCB milling machines that can efficiently separate metal dust. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices in separating metal dust and resin debris, the present invention aims to provide a dust collection and purification device for PCB milling machines.

[0006] The technical solution of this utility model is as follows: This utility model provides a dust collection and purification device for a PCB milling machine, including a trolley, a pouring frame, a pouring hopper, a collection frame, a magnetic roller, and a motor. The pouring frame is installed on the trolley, and the pouring hopper is set on the pouring frame. The collection frame is installed on one side of the trolley, and the magnetic roller is rotatably installed on the side of the trolley near the collection frame. The motor is symmetrically installed on the trolley, and the output shaft of the motor is connected to the axis of the magnetic roller.

[0007] Preferably, it also includes a piston cylinder, a multi-tube nozzle, a piston rod, an elastic element, a rack, and a missing gear. Piston cylinders are installed on both sides of the pouring frame, and several multi-tube nozzles are connected between the piston cylinders. A piston rod is slidably installed inside the piston cylinder. An elastic element is provided inside the piston cylinder. One end of the elastic element is connected to the piston cylinder, and the other end is connected to the piston rod. A rack is provided on the piston rod. Missing gears are installed at both ends of the shaft of the magnetic roller, and the missing gears are movably engaged with the rack.

[0008] Preferably, it also includes a scraper, which is installed on the side of the trolley near the magnetic roller and is in close contact with the magnetic roller.

[0009] Preferably, it also includes a collection tube, with the collection tube slidably installed on both sides of the collection frame.

[0010] Preferably, it also includes an n-shaped frame, a guide sleeve, a guide rod, a pusher plate, and a threaded rod. The n-shaped frame is installed on the trolley, a guide sleeve is installed on one side of the n-shaped frame, a threaded rod is rotatably installed on the guide sleeve, a pusher plate is threadedly connected to the threaded rod, and two guide rods are slidably installed on the pusher plate. Both guide rods are connected to the n-shaped frame.

[0011] Preferably, the scraper has an inverted V-shaped structure.

[0012] Preferably, the upper part of the collecting cylinder is funnel-shaped.

[0013] Preferably, the n-shaped frame is rotatably mounted with rollers.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a magnetic roller to adsorb and separate metallic substances from dust and debris. Other impurities slide down the inclined surface of the pouring frame to the collection frame, while the metallic substances on the magnetic roller are scraped off the scraper and collected in the collection cylinder, achieving the effect of efficient separation of metallic dust.

[0016] This invention utilizes the movable contact between the gear and the rack to cause the piston rod to reciprocate, thereby periodically compressing and releasing the air inside the piston cylinder. This effectively blows away dust and debris at the bottom of the discharge frame, accelerating dust separation and collection. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1: A dust collection and purification device for a PCB milling machine, such as Figure 1 , Figure 2 and Figure 5 As shown, the assembly includes a trolley 1, a pouring frame 2, a pouring hopper 3, a collection frame 4, a magnetic roller 5, a motor 6, a collection cylinder 11, and a scraper 12. The trolley 1 is equipped with the pouring frame 2, which has an inclined bottom. Using gravity, dust and debris slide naturally down the inclined surface, reducing the residence time of dust within the pouring frame 2 and thus improving dust collection efficiency. The pouring frame 2 is equipped with the pouring hopper 3, which has a funnel structure with a large opening at the top, effectively preventing dust and debris from scattering around the milling machine and ensuring that dust and debris can smoothly enter the pouring frame 2. A collection frame 4 is installed on the front of the trolley 1, and a magnetic roller 5 is rotatably mounted on the front of the trolley 1. The surface of the magnetic roller 5 has a strong magnetic field, which can adsorb metal particles in the dust. When the debris passes through the magnetic roller 5, the metal particles are adsorbed onto the roller surface, while non-metallic impurities (such as resin debris) continue to slide down the inclined surface of the pouring frame 2. Motors 6 are installed on both sides of the trolley 1, and the output shafts of the two motors 6 are connected to the axis of the magnetic roller 5. A scraper 12 is provided in the middle of the front side of the trolley 1. The scraper 12 is inverted V-shaped and one side is in close contact with the magnetic roller 5, so that when the magnetic roller 5 rotates, the scraper 12 can efficiently scrape off the metal particles adsorbed on the roller surface. Then, the metal particles slide down the scraper 12 for subsequent collection operations. Collection cylinders 11 are provided on both sides of the collection frame 4, and the collection cylinders 11 can be slid off. The upper part of the collection cylinder 11 is funnel-shaped, so that the operator can easily and quickly disassemble the collection cylinder 11 for cleaning or replacement.

[0027] like Figure 6 and Figure 7As shown, it also includes an n-shaped frame 13, a guide sleeve 14, a guide rod 15, a pusher plate 16, and a threaded rod 17. The n-shaped frame 13 is installed on the upper part of the trolley 1. Rollers are rotatably installed on the front side of the n-shaped frame 13, which facilitates the sliding of the device on the plate to clean impurities on the plate. The guide sleeve 14 is installed on the left side of the n-shaped frame 13. The threaded rod 17 is rotatably installed on the guide sleeve 14. The pusher plate 16 is threadedly connected to the lower part of the threaded rod 17. The height of the pusher plate 16 can be adjusted by rotating the threaded rod 17, which is convenient for cleaning plates of different heights. Two grooves are opened on the pusher plate 16, and two guide rods 15 are slidably installed in accordance with the grooves. Both guide rods 15 are connected to the n-shaped frame 13.

[0028] When it is necessary to clean up the dust and debris generated by the PCB milling machine, push the trolley 1 to the dust and debris area of ​​the PCB milling machine, then start the motor 6 to drive the magnetic roller 5 to rotate. The magnetic roller 5 starts working, allowing the generated dust and debris to fall directly into the pouring frame 2 along the pouring hopper 3. Then, it slides down the inclined surface of the pouring frame 2 and passes through the magnetic roller 5. The magnetic roller 5 adsorbs the metal substances in the dust and debris, while other impurities slide down the inclined surface of the pouring frame 2 to the collection frame 4 for collection. The rotation of the magnetic roller 5 drives the adsorbed metal substances to the vicinity of the scraper plate 12. The scraper plate 12 scrapes the metal substances away from the magnetic roller 5, allowing the metal substances to slide down to both sides of the scraper plate 12 to the collection cylinder 11 for collection. The magnetic force is used to separate metal particles from non-metallic impurities, thereby thoroughly separating the metal dust and preventing the metal particles from mixing with impurities such as resin debris, thus improving the purity of the metal substances and creating more favorable conditions for subsequent recycling.

[0029] Example 2: Based on Example 1, such as Figure 3 and Figure 4 As shown, it also includes piston cylinder 7, multi-tube nozzle 71, piston rod 8, elastic element 9, rack 10 and missing gear 18. Piston cylinder 7 is symmetrically installed on the pouring frame 2. A hollow pipe is connected between two piston cylinders 7. Nine multi-tube nozzles 71 are evenly spaced on the hollow pipe. Piston rod 8 is slidably installed inside piston cylinder 7. Elastic element 9 is installed inside piston cylinder 7. The rear end of elastic element 9 is connected to piston cylinder 7 and the front end is connected to piston rod 8. Rack 10 is installed on the front half of piston rod 8. Missing gear 18 is provided at both ends of the shaft of magnetic roller 5. Missing gear 18 is movably meshed with rack 10.

[0030] When a large amount of dust and debris falls simultaneously and needs to be separated quickly, the magnetic roller 5 rotates rapidly, and the gear 18 connected to both ends of its shaft rotates counterclockwise. When the gear 18 contacts the rack 10, the piston rod 8 connected to the rack 10 moves inward, thereby compressing the air in the piston cylinder 7. This causes the internal gas to be ejected from the multi-tube nozzle 71, forming a strong airflow. The airflow directly acts on the dust and debris at the bottom of the discharge box, increasing its sliding speed. When the gear 18 rotates to the toothless position, the gear 18 separates from the rack 10. Under the action of the elastic element 9, the piston rod 8 returns to its original position, realizing the automatic reciprocating motion of the piston rod 8. This allows the dust and debris to slide more quickly from the discharge box 2 to the magnetic roller 5 for separation, preventing dust from accumulating on the discharge box 2, reducing the residence time of dust inside the equipment, and thus improving dust collection efficiency.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
