Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding devices, specifically to a feeding adjustment device for diaper processing. Background Technology
[0002] Disposable diapers are a common daily necessity for babies, encompassing diaper pads, pull-up diapers, and other similar products. Dry diapers allow babies to sleep soundly through the night. Due to their high absorbency, they are commonly known as "disposable diapers." Highly absorbent polymer (HIP) is an excellent material for manufacturing baby diapers. It is made primarily from starch and acrylates and is characterized by its high absorbency and water retention. However, this powdery material is difficult to control during processing, thus requiring a feeding adjustment device.
[0003] During operation, existing feeding devices are prone to agglomeration of powdered superabsorbent resin due to factors such as changes in environmental humidity and electrostatic adsorption between particles. The existing feeding devices lack specific drainage structures, and the agglomerated raw material easily gets stuck in the inlet, valve gaps, or outlet pipe after entering the feeding channel, causing blockages. This necessitates frequent shutdowns for disassembly and cleaning, which not only interrupts the production process and reduces overall efficiency but also may result in waste due to material spillage during cleaning. Utility Model Content
[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a feeding adjustment device for diaper processing, thereby solving the problems mentioned in the background technology.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a feeding adjustment device for diaper processing, comprising a housing, wherein the housing includes a top plate disposed at the top and an internal feeding chamber and a feeding chamber;
[0006] The feeding chamber is connected to a feeding pipe, and the lower part of the discharging chamber is connected to a discharging pipe; a stirring mechanism is provided inside the feeding chamber, and the feeding pipe is fixedly installed at the center of the top plate;
[0007] The adjustment mechanism is located on the bottom surface of the top plate and includes a pair of valve plates, which are connected to the adjustment motor.
[0008] The stirring mechanism includes a stirring motor and a rotating shaft connected to the stirring motor. The spiral part is fixed on the rotating shaft, and the rotating shaft is vertically arranged in the discharge pipe.
[0009] Optionally, the stirring mechanism further includes a hollow rod, a drive shaft, and a bevel gear set. The output end of the stirring motor is connected to the drive shaft, and the drive shaft is connected to the rotating shaft via the bevel gear set. The hollow rod is arranged laterally in the feeding chamber, and the drive shaft is arranged inside the hollow rod.
[0010] Optionally, the rotating shaft is connected to a connecting rod via a connecting block, and a scraper is installed at the end of the connecting rod. The scraper contacts the inner wall of the feeding chamber, and the inner side of the feeding chamber gradually contracts inward from top to bottom to form a funnel-shaped structure.
[0011] Optionally, the adjustment mechanism further includes a first support platform, a second support platform, and a bidirectional lead screw. The adjustment motor drives the bidirectional lead screw, and two valve plates are respectively connected to the positive and negative thread sections of the bidirectional lead screw. The end of the valve plate away from the first support platform is slidably connected to the second support platform. Both the second support platform and the first support platform are fixed to the bottom surface of the top plate.
[0012] Optionally, the valve plate is provided with a connecting block one and a connecting block two at both ends. The connecting block one is a threaded block and is threadedly connected to a bidirectional lead screw. The support platform two is provided with a sliding rod. The connecting block two is provided with a through hole and is slidably connected to the sliding rod. The valve plate is fan-shaped and the two valve plates are mirror images of each other.
[0013] Optionally, a crossbar is fixed inside the feeding chamber, an installation box is installed in the middle of the crossbar, the hollow bar is connected to the installation box, and the bevel gear set is disposed inside the installation box.
[0014] Optionally, the top surface of the mounting box is provided with a truncated cone for dispersing and guiding the flow of materials.
[0015] Optionally, flanges are installed on both the feed pipe and the discharge pipe.
[0016] Compared with the prior art, this utility model has the following advantages:
[0017] 1. By continuously agitating the material conveyed in the discharge pipe through the agitation mechanism, and by controlling the channel opening through the valve plate of the regulating mechanism, the raw material agglomeration can be effectively resolved, material blockage can be avoided, and blockage in the production process can be significantly reduced. This not only reduces the frequency of downtime for cleaning and ensures the continuity of the production process, but also reduces raw material waste and improves the overall working efficiency and reliability of the equipment.
[0018] 2. By utilizing the valve plate combination driven by the bidirectional screw in the adjustment mechanism, the connection section between the feed pipe and the feed chamber can be smoothly and synchronously adjusted to control the material flow rate. At the same time, the funnel-shaped structure of the discharge chamber, together with the scraping action of the scraper, ensures that the material falls evenly without residue or deviation, thereby improving the quality stability and uniformity of the final product.

[0031] like Figure 1-6 As shown, this utility model discloses a feeding adjustment device for diaper processing, comprising a housing 1, which includes a top plate 13 and an internal feeding chamber 11 and a feeding chamber 12; the feeding chamber 11 is connected to a feeding pipe 4, and the lower part of the feeding chamber 12 is connected to a discharging pipe 5; a stirring mechanism 2 is provided in the feeding chamber 11, and the feeding pipe 4 is fixedly located at the center of the top plate 13; the adjustment mechanism 3 is located on the bottom surface of the top plate 13, and includes a pair of valve plates 31, which are connected to an adjustment motor 34; the stirring mechanism 2 includes a stirring motor 21 and a rotating shaft 25 connected to the stirring motor 21, a spiral part 26 is fixed on the rotating shaft 25, and the rotating shaft 25 is vertically arranged in the discharging pipe 5.
[0032] See Figure 1 In this embodiment, the housing 1 adopts a vertical cylindrical structure, with a top plate 13 installed on its top. The top plate 13 is a circular plate that seals with the opening at the top of the housing 1. Inside the housing 1, from top to bottom, there are a feeding chamber 11 and a discharging chamber 12. The feeding chamber 11 is located in the upper part of the housing 1, and the discharging chamber 12 is located in the lower part of the housing 1. The two are interconnected and coaxially arranged to ensure that the material can fall naturally from the feeding chamber 11 into the discharging chamber 12.
[0033] Among them, see Figure 3The feed pipe 4 is a stainless steel pipe, with its lower end connected to the top center of the feed chamber 11. The axis of the feed pipe 4 coincides with the central axis of the top plate 13, and the feed pipe 4 is fixedly installed at the center of the top plate 13. A flange 6 is welded and fixed to the outer wall of the upper end of the feed pipe 4. The flange 6 has 6 evenly distributed bolt holes for detachable connection with the discharge pipe of the external raw material storage tank via bolts. The discharge pipe 5 is also a stainless steel pipe, with its upper end connected to the lower center of the discharge chamber 12. The axis of the discharge pipe 5 coincides with the axis of the discharge chamber 12. A flange 6 is also welded and fixed to the outer wall of the lower end of the discharge pipe 5 for detachable connection with the raw material receiving pipe of the diaper production line via bolts.
[0034] Among them, see Figure 3 and Figure 4 The adjusting mechanism 3 is integrally installed on the bottom surface of the top plate 13 and located directly below the feed pipe 4. It is used to control the opening of the channel through which the feed pipe 4 conveys material to the feed chamber 11. Support platform 1 32 and support platform 2 33 are both cuboid blocks, symmetrically distributed, with their top surfaces fixed to the bottom surface of the top plate 13. Slide grooves are provided on opposite sides of support platform 1 32 and support platform 2 33. The slide groove of support platform 1 32 is used to install the bidirectional lead screw 35, and the slide groove of support platform 2 33 is used to install the sliding rod.
[0035] The adjusting motor 34 is a servo motor, which is fixedly installed on the outer wall of the support platform 32. The output shaft of the adjusting motor 34 passes through the through hole in the side wall of the support platform 32 and is connected to one end of the bidirectional lead screw 35. The other end of the bidirectional lead screw 35 is rotatably connected to the inner side wall of the slide groove of the support platform 32 through a bearing. The axis of the bidirectional lead screw 35 is set horizontally, and the slide rod is set parallel to the bidirectional lead screw 35.
[0036] The valve plate 31 is a fan-shaped stainless steel plate. The two valve plates 31 are arranged in a mirror symmetrical manner, and can completely cover the lower end of the feed pipe 4 when closed. One end of each valve plate 31 is integrally formed with a connecting block 311, which is an internally threaded block. The connecting blocks 311 of the two valve plates 31 are respectively threaded to the positive thread section and the negative thread section of the bidirectional lead screw 35. At the same time, the other end of each valve plate 31 is integrally formed with a connecting block 312, which has a circular through hole. The through hole of the connecting block 312 is slidably sleeved on the outer wall of the slide rod of the support platform 33, so that the valve plate 31 can slide along the length of the slide rod.
[0037] The stirring mechanism 2 includes a stirring motor 21, a hollow rod 22, a transmission shaft 23, a bevel gear set 24, a rotating shaft 25, a spiral part 26, a connecting block 27, a connecting rod 271, and a scraper 272.
[0038] The stirring motor 21 is a three-phase asynchronous motor, which is fixedly installed on the outer wall of the housing 1; the hollow rod 22 is a stainless steel round tube, which is horizontally fixedly installed in the feed chamber 11. The output shaft of the stirring motor 21 extends into the hollow rod 22 and is connected to one end of the transmission shaft 23 located inside the hollow rod 22.
[0039] See Figure 2 and Figure 5 The other end of the drive shaft 23 passes through the other end of the hollow rod 22 and extends into the mounting box 15, where it is fixedly connected to the driving bevel gear in the bevel gear set 24. The bevel gear set 24 consists of a driving bevel gear and a driven bevel gear, which mesh with each other to achieve the conversion of the power direction from horizontal to vertical.
[0040] The mounting box 15 is a hollow cylindrical stainless steel box, which is fixedly installed in the middle of the crossbar 14. The two ends of the crossbar 14 are fixed to the inner side wall of the feeding chamber 11. The crossbar 14 is set horizontally, so that the mounting box 15 is suspended in the center of the feeding chamber 11. The hollow rod 22 is connected to the inside of the mounting box 15, ensuring that the drive shaft 23 can extend into the mounting box 15 and connect with the bevel gear set 24. A cone 151 is fixed on the top surface of the mounting box 15, and its axis coincides with the axis of the feeding pipe 4. The cone 151 is used to disperse and guide the material falling from the feeding pipe 4 to the surrounding area, so as to avoid the material from accumulating directly on the top surface of the mounting box 15.
[0041] See Figure 5 The top end of the rotating shaft 25 is rotatably connected to the bottom surface of the mounting box 15 via a bearing (not shown). The lower part of the rotating shaft 25 extends vertically downward into the discharge pipe 5, and the rotating shaft 25 and the discharge pipe 5 are coaxially arranged. A horizontal plate 51 is provided at the bottom opening of the discharge pipe 5, and the other end of the rotating shaft 25 is rotatably connected to the center position of the horizontal plate 51 via a bearing (not shown). The spiral part is a stainless steel spiral blade, which is fixedly sleeved on the outer wall of the rod section of the rotating shaft 25 located inside the discharge pipe 5. When rotating, it can stir the material in the discharge pipe 5 and assist in conveying.
[0042] Furthermore, a connecting block 27 is fixedly connected to the outer wall of the rod segment inside the feeding chamber 12 of the rotating shaft 25. The connecting block 27 is a cuboid block, and connecting rods 271 are fixedly connected to both ends of the connecting block 27. The length of the connecting rods 271 matches the maximum inner diameter of the feeding chamber 12. A scraper 272 is fixedly installed at the end of the connecting rods 271. The scraper 272 is an arc-shaped stainless steel plate, and its arc is consistent with the arc of the inner wall of the feeding chamber 12. Its arc surface is in close contact with the inner side wall of the feeding chamber 12. The inner side of the feeding chamber 12 gradually contracts inward from top to bottom, forming a funnel-shaped structure, so that the material can slide down the inner wall of the feeding chamber 12 to the discharge pipe 5. At the same time, when the rotating shaft 25 rotates, it can drive the scraper 272 to scrape off the material remaining on the inner wall of the feeding chamber 12.
[0043] The working principle of this embodiment is as follows: During use, the device is connected to an external raw material storage tank via flange 6 on the feed pipe 4, and connected to the raw material receiving pipe of the diaper production line via flange 6 on the discharge pipe 5. The regulating motor 34 is started, and the bidirectional lead screw 35 rotates, driving two valve plates 31 to move in opposite directions along the slide bar to adjust the opening of the feed pipe 4 to convey material into the feed chamber 11, thereby controlling the discharge amount. Simultaneously, the stirring motor 21 is started, and the transmission shaft 23 drives the rotating shaft 25 to rotate via the bevel gear set 24. The spiral part 26 rotates inside the discharge pipe 5 to stir the material, prevent clumping, and assist in conveying. The scraper 272 rotates with the rotating shaft 25 to scrape off the material remaining on the inner wall of the discharge chamber 12, ensuring that the material falls smoothly into the discharge pipe 5 and is conveyed to the production line, effectively avoiding blockages and ensuring continuous production.
