Description

Technical Field

[0001] The invention relates to the technical field of sanitary napkin production, in particular to a dust removal device for a sanitary napkin production line. Background Art

[0002] Sanitary napkins are a highly absorbent material whose main components are high-molecular polymers and composite papers made of various materials. During the production process, a large amount of debris and dust will be generated, which seriously affects the health of workers on the production line. Therefore, the dust needs to be dealt with in a timely manner.

[0003] During the cleaning process, debris such as cotton wool and paper scraps will float around with the air, causing them to appear in many locations. During the dust removal process, the debris in different locations needs to be cleaned uniformly. However, cotton wool is larger in volume than dust particles, and it is easy to cause blockage during cleaning, affecting dust removal.

[0004] Most dust removal equipment uses the method of adsorption followed by filtration, which may cause cotton wool to block the filter port. Therefore, there should be a distinction between cleaning cotton wool and dust, and they should be cleaned in different ways. In addition, most dust removal equipment cannot adjust the dust removal position, resulting in a lot of dust and cotton wool hidden in the assembly line being carried away by air flow during the operation of the conveyor belt.

[0005] In the prior art, such as the invention "A dust removal device for a sanitary napkin production line" with application number 202210739443.7, it is mentioned that water droplets are coated on the filter bag to increase the adsorption effect. However, in addition to cotton wool, since the components of sanitary napkins contain flocs that will absorb water and swell, during the scraping process, the gel is easily smeared on the screen, causing local blockage and reducing the dust removal efficiency. Therefore, in order to solve the blockage problem caused by the gel, a measure is needed to prevent the mesh of the screen from being blocked. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The present embodiment provides a dust removal device for a sanitary napkin production line, comprising a workbench 11 and a first filter box 14 installed on the workbench 11, the first filter box 14 is connected to a plurality of exhaust pipes 12 extending to the workbench 11, the exhaust pipe 12 is provided with an extendable first corrugated pipe 13 and a second corrugated pipe 17, and an exhaust assembly 23 for sucking air along the exhaust pipe 12; A second filter box 15 is connected to the lower portion of the first filter box 14 , and a dust removal assembly 18 for sucking dust into the second filter box 15 is installed on the second filter box 15 .

[0021] The vacuum assembly 23 includes a vacuum pump 32 installed on the first filter box 14, the vacuum pipe 12 is connected to the cavity 31 in the first filter box 14 through the vacuum pump 32, and a guide rail is installed in the cavity 31 to drive the scraper 30 to move along the length direction of the first filter box 14.

[0022] The cavity 31 is provided with a plurality of stirrers 30 for stirring the internal liquid and particles. The cavity 31 is connected with a plurality of air inlet pipes 21 for injecting air into the cavity 31 and a plurality of air outlet pipes 28 for exhausting air.

[0023] A sieve plate 32 is provided in the first filter box 14, and a sieve hole 33 and a sieve slot 34 for filtering dust are provided on the sieve plate 32. An insert block 37 for inserting into the sieve hole 33 is provided below the sieve plate 32. A cleaning component 41 is provided in the first filter box 14 for driving the insert block 37 to move closer to or away from the sieve hole 33.

[0024] The cleaning assembly 41 includes a fixed shaft 38 fixedly connected to the cavity 31, a rotating plate 35 is rotatably connected to the fixed shaft 38, the plug block 37 is fixedly connected to the rotating plate 35, a spring 36 is fixedly connected between the lower part of the rotating plate 35 and the cavity 31, and a plurality of crushers 40 for crushing gel are provided in the cavity 31.

[0025] When dust removal is performed, the vacuum pump 32 is started, and all the dust or cotton wool in the air can be sucked into the cavity 31 through the vacuum pipe 12. After entering the cavity 31, it slowly settles and falls on the sieve plate 32. The gel or fragments that cannot pass through the sieve hole 33 will remain above the sieve plate 32. The scraper 30 can be driven to reciprocate through the guide rail, pushing the debris and dust above the sieve plate 32 to the sieve slot 34 and falling above the rotating plate 35.

[0026] Dust or fly ash will be discharged through the internal circulating air, and gel or debris will remain on the top of the rotating plate 35. When a certain weight of debris or gel accumulates on the rotating plate 35, it means that the sieve hole 33 is seriously blocked. The weight on the rotating plate 35 causes one end of the rotating plate 35 to sink, and the plug 37 is inserted into the sieve hole 33 to clear the blockage.

[0027] At this time, the spring 36 is stretched, and the cleaning block can be driven to push down the deposited dust on the rotating plate 35 through the second guide rail 391 provided on the rotating plate 35. After the weight is reduced, the rotating plate 35 is reset under the action of the spring 36.

[0028] The dust in the cavity 31 and the dust deposited on the rotating plate 35 can be broken up by the blender 40 , making it easier for the dust to be sucked out by the suction pump 22 .

[0029] The first filter box 14 is connected to the air storage box 16 through the air intake pipe 21 at the bottom. The first filter box 14 is equipped with an air pump 22 for driving the air intake pipe 21 to extract air from the air storage box 16. The air intake pipe 21 is provided with a first one-way valve along the direction from the air storage box 16 to the cavity 31.

[0030] The other end of the air outlet pipe 28 is communicated with the dust box 20 . The dust box 20 is provided with a drain pipe 26 for discharging waste gas. The air outlet pipe 28 is provided with a second one-way valve along the cavity 31 toward the dust box 20 .

[0031] Through the first one-way valve, the air flow at the air inlet end must flow from the air storage box 16 to the air inlet pipe 21, preventing air with dust from flowing into the air storage box 16, and through the second one-way valve, preventing dust from entering in the opposite direction.

[0032] Embodiment 2 See also Figure 3 , Figure 4 and Figure 5 This embodiment provides a dust removal device for a sanitary napkin production line. The second filter box 15 includes a fixing frame 25 for fixing the position of the second filter box 15 and a dust extraction shell 19 installed on the fixing frame 25. The dust removal component 18 includes a fan 24 installed in the dust extraction shell 19, and the fan 24 is used to suck air into the dust extraction shell 19.

[0033] A first connecting pipe 27 for air intake is provided between the dust extraction housing 19 and the air intake pipe 21 . A third one-way valve is provided in the first connecting pipe 21 for air flow along the air intake pipe 21 into the dust extraction housing 19 .

[0034] A second connecting pipe 29 for exhausting air is provided between the dust extraction housing 19 and the air outlet pipe 28 . A fourth one-way valve is provided in the second connecting pipe 29 for allowing air to flow along the dust extraction housing 19 toward the air outlet pipe 28 .

[0035] The fan 24 can absorb dust from other positions except the conveyor belt. At this position, as the bottom area of ​​the assembly line, more dust is absorbed to prevent dust from accumulating on the conveyor belt in the bottom area of ​​the assembly line, causing pollution of the conveyor belt and the workbench 11, and affecting the cleanliness of the product during transportation.

[0036] The dust is sucked into the second filter box 15 by the fan 24, and the air inlet pipe 21 is allowed to flow into the second filter box 15 during the air extraction process through the third one-way valve. At the other end, the dust is prevented from flowing into the second filter box 15 through the fourth one-way valve.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
