[0023] The embodiments of the present application will be described in detail below with reference to specific embodiments, so that how the present application applies technical means to solve technical problems and achieves technical effects can be fully understood and implemented.

[0024] Embodiment 1

[0025] Reference Figure 1 and Figure 2The utility model provides an online material dust removal mechanism of sanitary product equipment, including the static electricity eliminator 1 and dust remover 2 that are sequentially arranged in the online material conveying direction, before the whole dust removal and pollution removal process, online material will first pass through static electricity eliminator 1 to neutralize the static charge on the material surface, improve the dust removal effect and efficiency, the static electricity eliminator 1 can have multiple forms, and the subsequent dust remover 2 works just can not be limited, before material enters the dust removal link, first pass through the preposition static electricity eliminator 1 to neutralize the static charge on the material surface due to friction and extrusion. This step is crucial, because static electricity can enhance the adsorption of dust particles on the material surface, and the effect of the subsequent dust removal step will be greatly reduced.

[0026] The dust remover 2 includes a gas blowing system and a gas suction system arranged inside the dust remover 2.

[0027] The gas blowing system includes two gas blowing channels 21, and each gas blowing channel 21 includes a gas blowing port 211, a high-pressure gas chamber 212 connected to the gas blowing port 211, and an air inlet 214 connected to the high-pressure gas chamber 212.

[0028] The air inlet 214 is connected to a high-pressure gas source to provide power for subsequent ultrasonic vibration and dust blowing.

[0029] The high-pressure gas enters the high-pressure gas chamber 212 after entering the air inlet 214, so as to adjust and distribute the gas pressure as needed.

[0030] A high-pressure gas path 213 for generating ultrasonic vibration is arranged between the gas blowing port 211 and the high-pressure gas chamber 212. The high-pressure gas path 213 is a specially designed gas path system, in which high-pressure gas generates ultrasonic vibration and is guided to the material surface for high-frequency oscillation dust removal.

[0031] After passing through the specially designed high-pressure gas path 213, the high-pressure gas is sprayed from the gas blowing port 211 and directly acts on the surface of the material to be cleaned, using ultrasonic effect and high-speed airflow to strip dust and debris.

[0032] The dust remover 2 is made of aluminum, and the high-pressure gas path 213 is formed by wire cutting. The wire cutting technology can accurately cut the complex internal gas path, which not only ensures the stability and durability of the structure, but also ensures the stable and accurate flow of the gas in the internal channel.

[0033] The gas suction system includes a dust suction port 22 arranged between the two gas blowing ports 211, a dust suction chamber 23 connected to the dust suction port 22, and a negative pressure source connected to the dust suction chamber 23 for generating suction effect of the dust suction port 22. The dust suction port 22 extends along the width direction of the dust remover 2, has a sufficient coverage interval, and forms a large-flow dust suction port 22 with a wide coverage.

[0034] The negative pressure source adopts a high-power centrifugal dust suction device, which can timely and effectively suck the loosened and suspended dust and debris into the recycling device.

[0035] The technical solution adopts ultrasonic high-efficiency dust removal, simultaneously performs electrostatic elimination on the front and back surfaces of the material, and performs dust removal operation in a high-pressure gas mode, cooperates with the air suction system in the blowing position area to perform dust adsorption and collection, so as to form a thorough and efficient dust removal effect. Compared with the traditional dust removal equipment, the technical solution increases the pre-electrostatic pretreatment of the material, and makes the dust remaining on the online material surface be stripped through the two blowing channels 21, so that the dust removal effect is better. On the structure, a special high-pressure gas path 213 is designed inside the dust remover 2, which is different from simple high-pressure blowing. When the blown high-pressure gas contacts the online material, the high-frequency vibration is generated, the ultrasonic effect is formed, the high-speed airflow of the high-pressure gas is cooperated, and the dust and debris after the fixed point are blown and removed. The technical solution also has a certain cleaning effect on the dirt and stains on the surface of the material, and has a comprehensive and efficient dust removal effect. The material further passes through the specially designed ultrasonic dust removal module. The module makes the gas fluid generate ultrasonic vibration through a specific gas path structure. The vibration is transmitted to the material surface, causing the material surface and the dust particles attached thereto to also follow the high-frequency vibration, destroying the van der Waals force or other adhesion force between the dust on the material surface and the material, so that the dust is more easily stripped from the surface. In addition to generating ultrasonic waves, the high-pressure gas also serves as a kinetic energy carrier, directly blowing onto the material surface, further blowing the loosened dust and debris away from the material surface with the aid of the vibration effect induced by the ultrasonic waves; meanwhile, the high-power centrifugal dust suction device is cooperated to quickly and effectively suck the blown dust and debris into the recycling device through the negative pressure suction force, so as to ensure the air quality of the purification area and realize the recycling or safe handling of the dust resources.

[0036] In summary, the ultrasonic high-efficiency dust removal device skillfully combines electrostatic elimination, ultrasonic vibration assisted dust removal, and power blowing and dust suction technologies, and realizes efficient, non-destructive, and clean removal of dust and stains on the surface of various sanitary product materials. This innovative technology has significant value in improving the production efficiency and product quality of the sanitary product manufacturing industry, and improving the working environment.

[0037] Specifically, the two blowing channels 21 are symmetrically arranged, the two blowing ports 211 are inclined and the blowing directions are both towards the symmetry center of the two blowing channels 21, and the dust suction port 22 is located at the symmetry center of the two blowing ports 211. With such a design, the two blowing ports 211 synchronously output high-pressure gas, the airflow on both sides is equivalent and uniform, and after the dust on the material is vibrated and blown up, most of the free dust will float towards the center position of the dust remover 2 and be quickly sucked by the dust suction port 22, so that the blown dust and debris are timely removed and secondary pollution to the surrounding workpieces is prevented.

[0038] The device is arranged, and the output direction of the two blowout ports 211 is provided with a supporting component 3 for supporting the online material; here, the supporting component 3 is a roller, the online material is arranged between the supporting component 3 and the dust collector 2, the output direction of the two blowout ports 211 is towards the surface of the supporting component 3, the supporting component 3 can have sufficient support for the online material, avoid excessive vibration and shaking, meet the premise of ultrasonic vibration, and ensure the stability of the online material during dust removal; and the roller-shaped supporting component 3 extends into the recessed position between the two blowout ports 211, the space between the supporting component 3 and the dust collector 2 is reduced, the space between the two blowout ports 211 is reduced, and the dust and debris blown up can be timely extracted.

[0039] Under this design, for various material dust generated in the production of paper, paper towel, dry papermaking, dust-free paper, water absorption paper and other processes of sanitary product production equipment, it is a high-efficiency dust removal technology that can accurately and comprehensively adsorb, collect and process dust, reduce the influence of dust on product quality and production environment; this technology is not only suitable for paper product industry, but also extends to knitting and weaving, release paper, punched film and other industries, and a dust removal solution with wide applicability is designed, which can effectively treat stains and dust on the surface of various materials.

[0040] Meanwhile, on the basis of the above, the equipment functionality is expanded, and the dust suction chamber 23 is communicated with a dust removal equipment for dust post-processing. The dust removal equipment can be a filter core type dust removal machine, a bag type dust removal machine, or a same type of equipment with recycling, that is, an environmental protection treatment measure is carried out to realize the green and sustainable development of the production process.

[0041] In addition, the air suction system further comprises a dust concentration sensor arranged in the dust suction chamber 23 for detecting the dust concentration, and is adapted to a corresponding control system and driving member, so as to realize real-time monitoring of the dust concentration in the equipment operation through the high-precision sensor, and automatically adjust the cleaning intensity and frequency, so as to ensure the stability of the production process and the dust emission standard.

[0042] Embodiment two

[0043] Reference Figure 3Compared with the first embodiment, the two blowing channels 21 are divided into the first blowing channel 21a and the second blowing channel 21b, the air outlet pressure of the first blowing channel 21a is less than that of the second blowing channel 21b, and the output direction of the blowing port 211 on the second blowing channel 21b is opposite to the online material conveying direction; here, the opposite means that the output direction of the second blowing channel 21b is opposite to the conveying direction of the material, so that the dust is blown to the first blowing channel 21a direction and is blocked at the blowing port 211 of the second blowing channel 21b; and the first blowing channel 21a can use a relatively small air pressure to form a dust blocking air wall; specifically, the blowing port 211 of the first blowing channel 21a is vertically arranged, and the blowing port 211 of the second blowing channel 21b is obliquely arranged; in this structure, the dust on the forward conveying material is floated by the second blowing channel 21b and is limited in the space covered between the first blowing channel 21a and the second blowing channel 21b; this structure has less effect on the online material conveying compared with the first embodiment, and ensures the stability of the online material conveying; and since the first blowing channel 21a uses a small air pressure source, part of the energy consumption is reduced, and the consumption is low.

[0044] Although the present application has been specifically shown and described with reference to the preferred embodiments, it is understood that various changes in form and details can be made therein without departing from the spirit and scope of the application as defined by the appended claims.
