Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production, and in particular to a feeding device for a nonwoven fabric raw material mixing machine. Background Technology

[0002] Nonwoven fabric is a new type of textile material made by directly arranging fibers into a web structure and bonding them using processes such as bonding, needle punching, or melting, without the need for traditional spinning and weaving processes. This material possesses excellent properties such as lightweight, breathability, softness, and durability, and its production cost is relatively low, thus it is widely used in medical, agricultural, packaging, and construction fields. The main raw materials for nonwoven fabric production typically include polypropylene, polyester, and viscose fibers, with different raw materials imparting different properties to the nonwoven fabric. Before the raw materials undergo melting or chemical treatment, pre-mixing processing is usually required using mixing equipment. During this process, operators must use a feeding device to transport the raw materials into the mixing equipment.

[0003] In existing technologies, raw materials used in nonwoven fabric processing are generally transported to the mixing equipment via a feeding device for mixing. Common feeding devices include conveyor belts and screw conveyors. When a conveyor belt is used to transport raw materials, the raw materials are directly exposed to the external environment, so foreign matter may be mixed in during the transportation process. Screw conveyors, due to their relatively enclosed structure, can minimize the introduction of foreign matter during the transportation of raw materials. However, when the raw materials are discharged into the mixing equipment through the outlet of the screw conveyor, excess air inside the mixer may rise upwards, which may disperse some particulate dust from the raw materials into the air, potentially posing a health threat to workers around the equipment.

[0004] Therefore, it is necessary to provide a feeding device for a nonwoven fabric raw material mixer to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that when raw materials are discharged into the mixing equipment through the screw conveyor outlet, excess air inside the mixer may surge upwards, potentially scattering some particulate dust from the raw materials into the air and posing a potential threat to the health of workers around the equipment, this utility model provides a feeding device for a nonwoven fabric raw material mixer.

[0013] Compared with related technologies, the feeding device for a nonwoven fabric raw material mixer provided by this utility model has the following beneficial effects:

[0014] 1. The feeding device for the nonwoven fabric raw material mixer can reduce the dust content near the equipment, providing a certain degree of safety for the health of workers around the equipment: the set push trolley can limit the installation position of the screw conveyor. The operator can push the screw conveyor to the vicinity of the mixer by pushing the push trolley. Starting the screw conveyor can transport the nonwoven fabric raw material at the bottom to the upper part, and guide the raw material into the mixer through the feeding component. Starting the exhaust fan can control the feeding component to exhaust, thereby sucking out the air with dust rising from the mixer during feeding. The extracted air can be filtered by the filter screen, thereby reducing the dust content near the equipment and providing a certain degree of safety for the health of workers around the equipment. When there is a lot of raw material dust filtered by the filter screen, it can fall directly into the mixer through the feeding component, thereby reducing the waste of raw materials.

[0015] 2. The feeding device for the nonwoven fabric raw material mixer has a hopper that can hold the raw materials to be conveyed. The raw materials inside the hopper can enter the conveying pipe through the feed inlet. The starting motor can control the rotation of the spiral conveying plate through the shaft. The rotation of the spiral conveying plate can control the raw materials at the bottom of the conveying pipe to be conveyed upward. When the raw materials are conveyed to the top of the conveying pipe, they can be discharged outward through the discharge outlet. The inside of the connecting pipe is used to convey raw materials. When the exhaust fan is started, the exhaust port can facilitate air circulation. The mounting groove can restrict the installation position of the filter screen.

[0016] 3. The feeding device for the nonwoven fabric raw material mixer has a rectangular mounting frame that, when closed and located on the upper surface of the connecting pipe, is held in place by the pressing block under the elastic force of the first spring, thus limiting the closed position of the rectangular mounting frame. The folding telescopic tube can be adjusted for extension and retraction as needed, and the connecting pipe can be directly connected to the feed hole of the mixer, thereby ensuring that the air containing dust gushing out from inside the mixer can enter the connecting pipe. When the buckle is pressed and moved by the pressing block, the rectangular mounting frame can be lifted upward by the pushing column under the elastic force of the second spring, making it easy for personnel to open the rectangular mounting frame.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 A feeding device for a nonwoven fabric raw material mixer includes: a push trolley 1, a screw conveyor 2 fixedly connected to the upper surface of the push trolley 1, a feeding component 3 fixedly connected to one side of the top of the screw conveyor 2, a rectangular mounting frame 4 hinged to the upper surface of the feeding component 3, an exhaust fan 5 fixedly connected to the upper surface of the rectangular mounting frame 4, and a filter screen 6 disposed on the top of the feeding component 3 and located on the lower surface of the rectangular mounting frame 4.

[0025] In practical implementation, the trolley 1 in the feeding device of the nonwoven fabric raw material mixer can be moved by the user as needed, thereby pushing the screw conveyor 2 to the vicinity of the mixer and positioning the feeding assembly 3 installed on the screw conveyor 2 above the feed hole of the mixer. Then, by starting the screw conveyor 2, the nonwoven fabric raw material at the bottom can be conveyed upwards. When the raw material is conveyed into the feeding assembly 3, it can be guided into the mixer. Furthermore, a rectangular mounting frame 4 is hinged to the upper surface of the feeding assembly 3. The rectangular mounting frame 4 can restrict the installation position of the exhaust fan 5, and starting the exhaust fan 5 can control the feeding. Component 3 performs ventilation to draw in the dusty air rising from the mixer during feeding. The drawn-in air is filtered by filter screen 6. When there is a lot of raw material dust filtered down from the bottom of filter screen 6, it can fall directly into the mixer through feeding component 3, thereby reducing raw material waste and dust content near the equipment, thus providing a certain degree of safety for the health of workers around the equipment. The rectangular mounting frame 4 is hinged to the feeding component 3, and the user can control the rectangular mounting frame 4 to flip open. By opening the rectangular mounting frame 4, the filter screen 6 can be taken out for cleaning or replacement.

[0026] It should be noted that the exhaust fan 5 needs to control the airflow to prevent large particles of raw material from being sucked directly onto the filter screen 6 due to excessive airflow.

[0027] refer to Figure 1 As shown, the pusher trolley 1 includes a trolley plate 101 fixedly connected to the lower surface of the screw conveyor 2. Multiple moving wheels 102 are evenly fixedly connected to the lower surface of the trolley plate 101, and a pusher frame 103 is fixedly connected to one side of the trolley plate 101.

[0028] In practice, the platform 101 can support and limit the screw conveyor 2. The operator can move the platform 101 by pushing the frame 103 in conjunction with multiple moving wheels 102.

[0029] refer to Figure 1 , Figure 2 and Figure 3As shown, the screw conveyor 2 includes a conveying pipe 201 fixedly connected to the upper surface of the vehicle plate 101. A feed inlet 202 is provided on one side of the bottom end of the conveying pipe 201, through which the conveying pipe 201 passes. A discharge outlet 203 connected to the feeding assembly 3 is provided on one side of the top end of the conveying pipe 201. A motor 204 is fixedly connected to the upper surface of the conveying pipe 201. A shaft 205 is fixedly connected to the output end of the motor 204 through the conveying pipe 201. The lower end face of the shaft 205 is rotatably connected to the bottom of the inner wall of the conveying pipe 201. A screw conveying plate 206 is fixedly connected to the outer wall of the shaft 205. A hopper 207 connected to the feed inlet 202 is fixedly connected to one side of the bottom end of the conveying pipe 201.

[0030] In the specific implementation process, the inside of the hopper 207 is used to place the raw materials that need to be conveyed. The raw materials inside the hopper 207 can enter the inside of the conveying pipe 201 through the feed port 202. The starting motor 204 can control the spiral conveying plate 206 to rotate through the shaft 205. The rotation of the spiral conveying plate 206 can control the raw materials at the bottom of the conveying pipe 201 to be conveyed upward. When the raw materials are conveyed to the top of the conveying pipe 201, the raw materials can be discharged outward through the opened discharge port 203.

[0031] refer to Figure 2 , Figure 3 and Figure 4 As shown, the feeding assembly 3 includes a connecting pipe 301 fixedly connected to one side of the top end of the conveying pipe 201. The connecting pipe 301 is connected to the discharge port 203. One side of the rectangular mounting frame 4 is hinged to the upper surface of the connecting pipe 301. The top of the connecting pipe 301 is provided with an exhaust port 302 through which the connecting pipe 301 passes. The inside of the connecting pipe 301 is circumferentially cut with an installation groove 303 that is connected to the exhaust port 302. The filter screen 6 is located inside the installation groove 303.

[0032] In the specific implementation process, the inside of the connecting pipe 301 is used to transport raw materials. When the exhaust fan 5 is started, the air can circulate through the exhaust port 302. The installation slot 303 can restrict the installation position of the filter screen 6.

[0033] refer to Figure 5 As shown, a first storage groove 7 is provided at the top of the connecting pipe 301. A first spring 8 located inside the first storage groove 7 is elastically connected to one side of the inner wall of the connecting pipe 301. A pressing block 9 is elastically connected to the end of the first spring 8 away from the screw conveyor 2. A buckle 10 is fixedly connected to the upper surface of the pressing block 9. A slot 11 is provided on the lower surface of the rectangular mounting frame 4. The top of the buckle 10 is located inside the slot 11, and the two are interlocked.

[0034] In the specific implementation process, the first storage slot 7 can restrict the installation position of the first spring 8 and the pressing block 9. When the rectangular mounting frame 4 is closed and located on the upper surface of the connecting pipe 301, the pressing block 9 can keep the buckle 10 and the slot 11 locked together under the elastic force of the first spring 8, thus restricting the closed position of the rectangular mounting frame 4. The closing of the rectangular mounting frame 4 can restrict the installation position of the filter screen 6. When it is necessary to disassemble the filter screen 6, the user can press the pressing block 9 inward. The movement of the pressing block 9 can squeeze the first spring 8 to retract, and at the same time, it can also drive the buckle 10 to move and disengage from the slot 11, so that the user can easily open the rectangular mounting frame 4 to disassemble the filter screen 6.

[0035] refer to Figure 2 As shown, a folding telescopic tube 15 is fixedly connected to the lower end face of the connecting tube 301, and a connecting tube 16 is fixedly connected to the lower end face of the folding telescopic tube 15.

[0036] In the specific implementation process, the folding telescopic tube 15 can be extended and adjusted as needed, and the connecting tube 16 can be directly connected to the feed hole of the mixer, thereby further ensuring that the air containing dust that flows out from inside the mixer can enter the connecting tube 301.

[0037] refer to Figure 5 As shown, a second storage slot 12 is provided on the upper surface of the connecting pipe 301. The second storage slot 12 is located between the exhaust port 302 and the first storage slot 7. A second spring 13 located inside the second storage slot 12 is elastically connected to one side of the inner wall of the connecting pipe 301. A push column 14 is fixedly connected to the upper end face of the second spring 13. The upper end face of the push column 14 abuts against the lower surface of the rectangular mounting frame 4.

[0038] In the specific implementation process, the second storage slot 12 can restrict the installation position of the second spring 13 and the push column 14. When the buckle 10 is pressed and moved by the pressing block 9, the rectangular mounting frame 4 can be lifted upward by the push column 14 under the elastic force of the second spring 13, so that it is convenient for personnel to open the rectangular mounting frame 4.

[0039] The working principle of the feeding device for a nonwoven fabric raw material mixer provided by this utility model is as follows:

[0040] In use, the operator can push the trolley 1 to move the screw conveyor 2 to the vicinity of the mixer, and position the feeding component 3 above the feed port of the mixer. By starting the screw conveyor 2, the non-woven fabric raw material at the bottom can be transported upwards, and the raw material is guided into the mixer through the feeding component 3. The exhaust fan 5 is installed above the feeding component 3 through the rectangular mounting frame 4, and the filter screen 6 is installed between the top of the feeding component 3 and the rectangular mounting frame 4. Starting the exhaust fan 5 can control the feeding component 3 to exhaust air, thereby sucking up the dusty air rising from the mixer during feeding. The sucked air can be filtered by the filter screen 6. When there is a lot of raw material dust filtered down from the bottom of the filter screen 6, it can fall directly into the mixer through the feeding component 3, thereby reducing the waste of raw materials and reducing the dust content near the equipment, which can provide a certain degree of safety protection for the health of the workers around the equipment.
