Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric manufacturing technology, and in particular to a nonwoven fabric manufacturing device with an air permeability and water repellency detection structure. Background Technology

[0002] Nonwoven fabrics, also known as non-woven textiles, are widely used in numerous fields such as medical, hygiene, protection, and filtration due to their advantages of short production processes, high output, low cost, and wide range of applications. In many applications, the air permeability and water repellency of nonwoven fabrics are crucial indicators. Therefore, air permeability and water repellency testing is necessary during the fabric production process. However, most existing nonwoven fabric manufacturing equipment focuses on the production process itself and lacks real-time, online testing of the product's air permeability and water repellency. Traditional testing methods typically involve taking samples from the finished product for offline testing after production is completed. This method has significant drawbacks, as follows:

[0003] Traditional testing is usually conducted by sampling after the nonwoven fabric is produced. This is a post-production test, which means that once the product is found to be substandard in terms of air permeability or water repellency, the entire batch of products may have already been produced in large quantities, resulting in a large backlog of substandard products and a waste of raw materials, manpower and time. Moreover, the low sampling frequency makes it difficult to fully reflect the quality of the entire batch of products, and it is easy to miss the detection, allowing some substandard products to enter the market.

[0004] Sampling and offline testing can only reflect the performance of some products and cannot fully and accurately represent the quality of the entire batch of products. Due to various unstable factors that may exist in the production process, the performance of nonwoven fabrics produced at different locations and at different times may vary. Sampling and testing may miss some quality problems. In addition, sampling and offline testing require additional time and manpower.

[0005] Most manufacturers have separate manufacturing and testing equipment, which not only takes up a lot of production space but also increases equipment procurement and maintenance costs. Utility Model Content

[0006] This utility model relates to a nonwoven fabric manufacturing device with a breathable and water-repellent detection structure. The device involves activating a cylinder, which pushes a connecting frame downwards, causing the drainage housing to descend until the two sealing gaskets are in close contact with the upper and lower parts of the fabric, forming a sealed space. Turning on the electric motor causes rubber plugs to rise. One rubber plug moves upwards, pushing the liquid inside the support housing to locally impact the fabric; the other rubber plug moves upwards, compressing air. When water seepage or air leakage occurs in the fabric, the air pressure passes through the connecting sleeve and enters the fabric's breathable and water-repellent detector. The detection values ​​displayed by the detector are observed and recorded, completing the automatic fabric detection process.

[0007] This utility model provides a nonwoven fabric manufacturing device with a breathable and water-repellent detection structure, specifically including: a nonwoven fabric manufacturing body, a first stabilizing plate with an L-shaped structure on one side of the upper part of the nonwoven fabric manufacturing body, a vertical stabilizing hole with a cylinder inserted inside the stabilizing hole, a second stabilizing plate with a set of threaded holes and a rotating hole at the bottom of the second stabilizing plate, an electric motor installed on one side of the second stabilizing plate, a vertical rotating hole with a threaded rod inserted inside the rotating hole, a solenoid valve installed at the bottom of the nonwoven fabric manufacturing body, a connecting frame installed at the bottom of the cylinder push rod, a drain housing installed at the bottom of the connecting frame, the cylinder, the connecting frame, and the drain housing cooperate to form a drain mechanism, a support housing installed at the bottom of the nonwoven fabric manufacturing body, a bolt mounting hole on each side of the support housing, a sealing gasket installed at the bottom of the drain housing, and a sealing gasket installed at the top of the support housing.

[0008] Furthermore, a mounting hole is provided on each side of the drainage housing, and the bottom of the connecting bracket extends into the interior of the mounting hole.

[0009] Furthermore, a stabilizing groove is provided at the edge of the sealing gasket, and the bottom of the drainage housing and the top of the support housing extend into the interior of the stabilizing groove.

[0010] Furthermore, a drive bevel gear is installed on the outer side of the drive shaft of the electric motor, and a driven bevel gear is installed at the bottom of the threaded rod, with the drive bevel gear and the driven bevel gear meshing.

[0011] Furthermore, a lifting plate is installed on the outer side of the threaded rod, and a threaded hole corresponding to the threaded rod is opened in the middle of the lifting plate. The threaded rod passes through the inside of the threaded hole. A vertical positioning post is provided on each side of the lifting plate, and two sliding holes are opened at the bottom of the support housing. The positioning post passes through the inside of the sliding holes.

[0012] Furthermore, a rubber stopper is installed above the positioning post, and a positioning groove is formed above the positioning post. The positioning groove has a circular structure, and a positioning ring is provided on the inner side of the rubber stopper, extending into the interior of the positioning groove.

[0013] Furthermore, a transverse mounting hole is opened on one side of the support housing, and a water pipe is installed inside the mounting hole. The electric motor, threaded rod, lifting plate, positioning column, rubber plug, support housing, and water pipe cooperate to form a pressure application mechanism. The bottom of the water pipe passes through the inside of the solenoid valve, and the outer side of the rubber plug contacts the inner wall of the support housing.

[0014] Furthermore, the drainage shell has two drainage spaces, and a connecting sleeve is provided in the middle of the drainage space, which is connected to the interior of the drainage space.

[0015] This utility model provides a nonwoven fabric manufacturing device with an air permeability and water repellency detection structure, which has the following beneficial effects:

[0016] This invention incorporates a nonwoven fabric air permeability and water repellency detection structure into the nonwoven fabric manufacturing device. By integrating the air permeability and water repellency detection structure into the nonwoven fabric manufacturing process, the air permeability and water repellency performance of the nonwoven fabric can be detected in real time during production. Compared with traditional sampling inspection methods, this can promptly identify quality problems, improve product quality stability, and reduce waste of raw materials and production costs.

[0017] By controlling the electric motor to drive the threaded rod to rotate, the lifting plate and positioning column move up and down. Then, the rubber plug pushes the liquid and compressed air in the support shell to locally impact the fabric, simulating the pressure conditions that nonwoven fabrics may encounter in actual use scenarios. This makes the test results more in line with actual application needs and improves the reliability and practicality of the test.

[0018] Operators only need to start the cylinder and electric motor and control the solenoid valve to perform the fabric inspection operation. The operation process is simple and easy to understand. The automated operation of the device reduces manual intervention, lowers labor intensity, and improves inspection efficiency.

[0019] The detection structure is applicable to the detection of nonwoven fabrics of different specifications and materials. Simply adjust the position of the fabric so that it passes between the two sealing gaskets. By setting a water pump, the water-repellent detection liquid can be automatically added to the inside of the support housing. The detection structure can flexibly adjust the liquid delivery volume and pressure during detection according to actual needs to meet different detection standards and requirements, thus enhancing the expandability and adaptability of the device.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Example 1: Please refer to Figures 1 to 9 :

[0040] This utility model proposes a nonwoven fabric manufacturing device with a breathable and water-repellent detection structure, comprising: a nonwoven fabric manufacturing body 1, a first stabilizing plate 101 located on one side of the upper part of the nonwoven fabric manufacturing body 1, the first stabilizing plate 101 having an L-shaped structure, a vertical stabilizing hole opened on one side of the first stabilizing plate 101, a cylinder 201 inserted inside the stabilizing hole, and an interference fit structure to stabilize the installation position of the cylinder 201 by the first stabilizing plate 101 in conjunction with the stabilizing hole, the cylinder 201 being selected according to actual needs from existing technology models, a second stabilizing plate located at the bottom of the nonwoven fabric manufacturing body 1, a set of threaded holes and a rotating hole opened at the bottom of the second stabilizing plate, an installation hole opened on each side of the drainage housing 203, the bottom of the connecting frame 202 extending into the interior of the installation hole, the connecting frame 202 and the drainage housing 203 being stably assembled by an interference fit structure, so that the connecting frame 202 and the drainage housing 203 can move up and down synchronously and stably;

[0041] In this embodiment, an electric motor 301 is installed on one side of the second stabilizing plate. A standard model of electric motor 301 is selected according to actual needs. Matching bolts are installed between the electric motor 301 and the threaded hole. After bolt installation, the installation position of the electric motor 301 is stabilized. The thread pitch of the threaded hole and bolts is machined according to actual needs. A vertical rotating hole is opened on one side of the second stabilizing plate, and a threaded rod 302 is inserted inside the rotating hole. The horizontal positioning structure of the rotating hole in the prior art is used to vertically position the rotation of the threaded rod 302, enabling the threaded rod 302 to rotate stably in place. A driving bevel gear is installed on the outer side of the drive shaft of the electric motor 301, and a driven bevel gear is installed at the bottom of the threaded rod 302. The driving bevel gear and the driven bevel gear mesh, thus controlling the electric motor 301 to drive the threaded rod 302 to rotate. A lifting plate 303 is installed on the outer side of the threaded rod 302, and a [missing information - likely a hole or opening] is opened in the middle of the lifting plate 303. The threaded hole corresponding to the threaded rod 302 passes through the inside of the threaded hole. The pitch of the threaded hole and the threaded rod 302 is processed according to actual needs so that the threaded hole and the threaded rod 302 can be threadedly connected. A vertical positioning post 304 is provided on each side of the lifting plate 303. Two sliding holes are opened at the bottom of the support housing 306. The positioning post 304 passes through the inside of the sliding holes. After the support housing 306 is stabilized, it cooperates with the sliding holes to achieve the effect of circumferential and lateral positioning of the lifting plate 303 and the positioning post 304. Therefore, when the threaded rod 302 rotates, it can control the lifting plate 303 and the positioning post 304 to move up and down. A rubber plug 305 is installed at the top of the positioning post 304. A positioning groove is opened at the top of the positioning post 304. The positioning groove is a circular ring structure. A positioning ring is provided on the inner side of the rubber plug 305. The positioning ring extends into the inside of the positioning groove. The positioning groove and the positioning ring achieve the effect of stable assembly of the positioning post 304 and the rubber plug 305.

[0042] In this embodiment, a transverse mounting hole is opened on one side of the support housing 306. A water pipe 30601 is installed inside the mounting hole. The electric motor 301, threaded rod 302, lifting plate 303, positioning post 304, rubber plug 305, support housing 306, and water pipe 30601 cooperate to form a pressure application mechanism 3. The water pipe 30601 is made of a rigid material according to actual needs. The material of the water pipe 30601 can be plastic or metal. The bottom of the water pipe 30601 passes through the interior of the solenoid valve 5. Referring to the solenoid valve 5 in the prior art... The connection and control structure of water pipe 30601 are assembled by solenoid valve 5 and water pipe 30601. By controlling the opening and closing of solenoid valve 5, the effect of blocking and flowing on one side of water pipe 30601 is achieved. The outer side of rubber plug 305 contacts the inner wall of support housing 306. Since rubber plug 305 is elastic, when solenoid valve 5 is closed, one of rubber plugs 305 moves upward and can push the liquid inside support housing 306. At this time, the liquid makes a local impact on the fabric. The other rubber plug 305 moves upward and compresses the air. The compression control makes a local impact on the fabric.

[0043] In this embodiment, a solenoid valve 5 is installed at the bottom of the nonwoven fabric manufacturing body 1. A connecting frame 202 is installed at the bottom of the push rod of the cylinder 201. The assembly structure of the push rod and the connecting frame 202 can utilize an interference fit assembly structure or a welding method. The cylinder 201 controls the push rod to push the connecting frame 202 to move up and down. A drainage housing 203 is installed at the bottom of the connecting frame 202. The cylinder 201, the connecting frame 202, and the drainage housing 203 cooperate to form a drainage mechanism 2. A support housing 306 is installed at the bottom of the nonwoven fabric manufacturing body 1. A bolt mounting hole is opened on each side of the support housing 306. Matching bolts need to be installed at the bolt mounting holes. After the bolts are installed, the support housing 306 is stabilized. A sealing gasket 4 is installed at the bottom of the drainage housing 203 and at the top of the support housing 306. A stabilizing groove is provided at the edge of the sealing gasket 4. The bottom of the drainage housing 203 and the support housing 306 are connected. The upper part of 6 extends into the interior of the stabilizing groove. The stabilizing groove makes the installation position of the sealing gasket 4 stable. The sealing gasket 4 is made of rubber material with good sealing effect according to actual needs. When the two sealing gaskets 4 are in close contact with the upper and lower positions of the fabric under the pressure of the cylinder 201, the sealing gasket 4 achieves the sealing effect of the docking position of the drainage shell 203 and the support shell 306. The drainage shell 203 has two drainage spaces. A connecting sleeve is provided in the middle of the drainage space. The connecting sleeve is connected to the interior of the drainage space. A fabric air permeability and water repellency detector of the prior art needs to be installed on the nonwoven fabric manufacturing body 1. A drainage pipe is installed between the connecting sleeve and the fabric air permeability and water repellency detector according to the prior art. After the cylinder 201 pushes the drainage shell 203 downward, the two sealing gaskets 4 can be in close contact with the upper and lower positions of the fabric respectively. At this time, when the fabric seeps water or leaks air, the air pressure will pass through the connecting sleeve and enter the interior of the fabric air permeability and water repellency detector. At this time, the fabric air permeability and water repellency detector can display the fabric air permeability and water repellency detection value.

[0044] Example 2, based on Example 1, such as Figures 1-9 As shown, a nonwoven fabric is laid on top of the nonwoven fabric manufacturing body 1, and the fabric passes between two sealing gaskets 4. The nonwoven fabric manufacturing body 1 is selected from existing technologies according to actual needs.

[0045] Example 3, based on Example 1, such as Figures 1-9 As shown, a water pump based on existing technology is set up according to actual needs, and the water pump needs to be connected to the bottom of the diversion pipe and water pipe 30601 so that the water pump can effectively transport liquid to the inside of water pipe 30601.

[0046] The working principle of this embodiment:

[0047] The cylinder 201, connecting frame 202, drainage housing 203, electric motor 301, threaded rod 302, lifting plate 303, positioning column 304, rubber plug 305, support housing 306, water pipe 30601, sealing gasket 4, and solenoid valve 5 are assembled onto one side of the nonwoven fabric manufacturing body 1 according to the structure described above.

[0048] The operator needs to install the existing fabric breathability and water repellency detector on the nonwoven fabric manufacturing body 1, and connect the connecting sleeve to the fabric breathability and water repellency detector through the drainage pipe according to the existing technology, lay the nonwoven fabric on top of the nonwoven fabric manufacturing body 1, and let the fabric pass through the two sealing gaskets 4.

[0049] The cylinder 201 is activated, causing its push rod to move the connecting frame 202 downwards, which in turn causes the drainage housing 203 to descend until the two sealing gaskets 4 are in close contact with the upper and lower positions of the fabric, forming a sealed space. The electric motor 301 is then turned on, driving the threaded rod 302 to rotate, causing the lifting plate 303 and the positioning column 304 to move upwards. The rubber plug 305 above the positioning column 304 will rise accordingly. One rubber plug 305 moves upwards, pushing the liquid inside the support housing 306 to locally impact the fabric; the other rubber plug 305 moves upwards, compressing air, which also locally impacts the fabric.

[0050] The solenoid valve 5 is controlled to open. When the solenoid valve 5 is open, water pipe 30601 flows. At this time, an appropriate amount of liquid is added to the inside of the support housing 306 in conjunction with the water pump and water pipe 30601. The solenoid valve 5 is then closed, and the liquid is effectively stored. The movement of the rubber stopper 305 is used to control the liquid and air. When the fabric leaks water or air, the air pressure will pass through the connecting sleeve and enter the inside of the fabric air permeability and water repellency detector. At this time, the detection value displayed by the fabric air permeability and water repellency detector is observed and recorded. After the fabric detection is completed, the electric motor 301 is turned off first, so that the threaded rod 302 stops rotating. Then, the cylinder 201 is started, so that the drainage housing 203 rises and resets, completing the automatic detection process of the fabric.
