Description

Technical Field

[0001] This utility model relates to the field of needle punching device technology, specifically to a low-damage needle punching device component for composite filter media. Background Technology

[0002] The core component of a baghouse dust collector is the filter bag, whose main raw material is chemical fiber. Currently commonly used materials include PPS, PI, aramid, PTFE, glass fiber, and polyvinyl alcohol fiber. The long-term operating temperature of these fibers is generally between 160 and 240℃.

[0003] However, the fire resistance of the aforementioned materials is not outstanding in high-temperature environments, and they still face many risks of being burned or damaged in practical applications. For example, in the operation and management of dust collectors, if the ash hopper is not unloaded in a timely manner, the ash level in the hopper will accumulate over a long period of time, remaining high and directly contacting or even submerging the bottom of the filter bags, resulting in high-temperature burns to the filter bags.

[0004] To address the poor fire resistance of commonly used filter media, pre-oxidized fibers and needle-punching technology are employed. Pre-oxidized fibers exhibit significant electrostatic activity during the carding and web-laying process, making them prone to tangling with rollers and sticking to the screen, thus hindering the formation of a web.

[0016] This invention provides a low-damage needle-punching device assembly for composite filter media. It has the following beneficial effects:

[0017] 1. The low-damage needle punching device assembly for this composite filter material includes a crossbar, a carding roller, a support plate, and a heating module. A sprayer is installed at the lower end of the support plate. The sprayer sprays air that adheres to the surface of the carding roller, while the heating module heats the surface of the carding roller, causing the droplets adhering to the surface of the carding roller to evaporate, increasing the humidity of the surrounding environment, reducing static electricity generated by friction, and allowing the static charge to dissipate more quickly due to the increased air humidity. This reduces static electricity generated by friction during the carding process.

The carding roller is equipped with a retractable needle. After the needle retracts into the carding roller, the lint on the surface of the needle is scraped off and adsorbed onto the surface of the carding roller. By the contact between the upper end of the support plate and the surface of the carding roller, the carding roller rotates clockwise and scrapes off the lint, which falls into the lint groove, thus collecting and cleaning impurities from the surface of the carding roller.

Detailed Implementation

[0024] This utility model embodiment provides a low-damage needle-punching device assembly for composite filter media, such as... Figures 1-4 As shown, the system includes a platform 1, a support welded to the top of the platform 1, a crossbar 2 above the platform 1, and a carding roller 3 on the left side of the crossbar 2. The support is welded to the shaft end of the crossbar 2, and the support is pivotally connected to the shaft end of the carding roller 3. The surface of the carding roller 3 has multiple pinholes 31, and the inside of the carding roller 3 has a receiving cavity 33 that corresponds to and communicates with the pinholes 31. A needle 34 is slidably fitted inside the receiving cavity 33.

[0025] A support plate 4 is provided between the crossbar 2 and the carding roller 3. The end of the support plate 4 is also welded to the bracket on the platform 1. The fibers pass under the crossbar 2, under the support plate 4, and under the carding roller 3 in sequence along the feeding direction.

[0026] The upper end of the support plate 4 is inclined to the left and abuts against the surface of the carding roller 3. A sprayer is fixedly installed on the lower end of the support plate 4 facing the side of the carding roller 3. A lint trough 5 is fixedly installed on the upper end of the support plate 4. A heating module 6 is fixedly installed in the middle section of the support plate 4. The working end of the heating module 6 is in contact with the surface of the carding roller 3.

[0027] During operation, the sprayer sprays mist, which comes into contact with the carding roller 3 and the fibers. This wets the surface of the carding roller 3. The heating module 6 then heats the carding roller 3. The evaporation of the liquid droplets on the surface of the carding roller 3 after heating increases the humidity of the surrounding environment, reducing static electricity generated by friction. At the same time, the increased air humidity allows the static charge to dissipate more quickly.

[0028] An electromagnet module 35 is fixedly installed on the inner wall of the storage cavity 33 away from the needle hole 31. A magnet is embedded at the end of the needle 34 near the electromagnet module 35. A groove 36 corresponding to the storage cavity 33 is opened in the combing roller 3. A ball bearing 37 is placed in the groove 36. A touch switch 38 is fixedly installed in the groove 36.

[0029] A microcontroller and a battery pack are also fixedly installed inside the carding roller 3. The microcontroller, battery pack, touch switch 38, and electromagnet module 35 are electrically connected.

[0030] When the electromagnet module 35 generates a magnetic field, there is a repulsive force between the electromagnet module 35 and the needle 34.

[0031] Working principle: When a needle-punch 34 moves to below the carding roller 3, the ball bearing 37 slides under its own weight and contacts the touch switch 38. The needle-punch 34 extends out of the receiving cavity 33. At the same time, the electromagnet module 35 is energized, generating a magnetic field that supports the needle-punch 34, allowing it to penetrate the fiber. When the needle-punch 34 rotates upward, the ball bearing 37 moves away from the touch switch 38, the electromagnet module 35 is de-energized, and the needle-punch 34 slides back into the receiving cavity 33.

[0032] Broken fiber impurities, when re-collected into the receiving cavity 33 by the needle punch 34, are scraped off by the edge of the needle hole 31 and adhere to the surface of the carding roller 3. They are eventually scraped off by the upper end of the support plate 4 and fall into the lint trough 5.

[0033] The crossbar 2 has two chambers, chamber 1 21 and chamber 22, located between chamber 1 21. A needle plate 7 is slidably fitted inside chamber 22, and the needle plate 7 can move up and down. Multiple needles 71 are welded to the bottom of the needle plate 7. When the needle plate 7 descends to its lowest point, the needles 71 extend from the bottom of the crossbar 2, serving a pre-combing function.

[0034] A sliding hole 72 is provided at the end of the needle plate 7. A vertical sliding column 25 is welded inside the second chamber 22, passing through the second chamber 22. A spring 73 is welded between the needle plate 7 and the top of the inner wall of the second chamber 22. A cam 8 is provided inside the second chamber 22, located directly above the needle plate 7. When the cam 8 is vertical, it presses down on the needle plate 7, causing it to descend. When the cam 8 is horizontal, the spring 73 raises the needle plate 7. A motor is fixedly mounted on the shaft end of the cam 8, and the motor is fixedly mounted to the inner wall of the second chamber 22.

[0035] A motor 23 is fixedly installed inside chamber 21. The drive shaft of the motor 23 extends to the outside of the crossbar 2 and is welded with gear 24. Gear 32 is fixedly installed at the end of the combing roller 3 shaft. A toothed belt 9 is connected between gear 24 and gear 32.

[0036] In summary, the low-damage needle punching device assembly for this composite filter material comprises a crossbar 2, a carding roller 3, a support plate 4, and a heating module 6. A sprayer is installed at the lower end of the support plate 4. The sprayer sprays air that adheres to the surface of the carding roller 3, while the heating module 6 heats the surface of the carding roller 3, causing the droplets adhering to the surface to evaporate, increasing the ambient humidity, and reducing static electricity generated by friction. Furthermore, the increased air humidity allows the static charge to dissipate more quickly. This reduces static electricity generated by friction during the carding process.

[0037] Furthermore, the upper end of the support plate 4 is connected to a lint trough 5, and the carding roller 3 is equipped with retractable needles 34. After the needles 34 are retracted into the carding roller 3, the lint on the surface of the needles 34 is scraped off and adsorbed onto the surface of the carding roller 3. By the contact between the upper end of the support plate 4 and the surface of the carding roller 3, the carding roller 3 rotates clockwise and scrapes off the lint, which falls into the lint trough 5, thus collecting and cleaning impurities from the surface of the carding roller 3.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
