Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production equipment technology, and in particular to a nonwoven fabric multi-material mixing and feeding system. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth or non-woven material, is a sheet or web-like material formed by directly bonding fibers together using physical, chemical, or mechanical methods, or by hot pressing or needle punching, without the need for traditional spinning and weaving processes. Its production process eliminates the spinning and weaving stages, thus featuring a short process flow, high production efficiency, and low cost. In the production of nonwoven fabric, the uniformity of raw material mixing directly affects product quality. Traditional feeding systems often supply single materials, making it difficult to meet the needs of multi-material mixing. With the expansion of nonwoven fabric applications, the requirements for raw material diversity and mixing precision are increasingly increasing.

[0003] A search revealed Chinese Patent Publication No. CN222034357U, which discloses a material mixing device including a mixing cylinder, a cylinder cover, a feed pipe, and a stirring assembly. The mixing cylinder has a discharge pipe at its bottom, and the cylinder cover is fitted onto the mixing cylinder. The cylinder cover has multiple feed pipes, and the feed pipe includes a conical section and a cylindrical section. The conical section is connected above the cylindrical section and fixed inside the mixing cylinder, located below the multiple feed pipes. The stirring assembly is disposed inside the mixing cylinder to stir the various materials within it. This application, by using a feed pipe, can achieve a first mixing of multiple materials, followed by a second mixing under the action of the stirring assembly, improving the mixing uniformity and efficiency. However, in practical use, this device mixes materials through the feed pipe and the stirring assembly, making it difficult to adjust the mixing ratio in real time during mixing, thus failing to adapt to dynamic formula changes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nonwoven fabric multi-material mixing and feeding system, which aims to improve the problem in the prior art that the mixing ratio cannot be adjusted well in real time during mixing, and thus cannot adapt to dynamic formula changes.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a non-woven fabric multi-material mixing and feeding system, including a base frame, a fixed frame fixedly connected to the top wall of the base frame, a mixing tank fixedly connected inside the fixed frame, multiple bolt metering mechanisms equidistantly arranged on the top of the mixing tank, the bolt metering mechanisms being used to improve the proportion adjustment during material mixing, a drying mixing mechanism being arranged at the bottom of the bolt metering mechanisms, the drying mixing mechanism being used to improve the dryness of the mixed materials, and installation mechanisms being arranged on both the left and right sides of the base frame; the bolt metering mechanism includes multiple injection pipes, the bottom ends of the multiple injection pipes being respectively connected to the outer side of the top wall of the mixing tank, the outer wall of the injection pipes being connected to a feed inlet, a loss-in-weight weighing scale fixedly connected to the top of the injection pipes, a servo motor fixedly connected inside the loss-in-weight weighing scale, a conveying auger fixedly connected to the output end of the servo motor, a variable frequency motor fixedly connected to the middle of the top wall of the mixing tank, a rotating column fixedly connected to the output end of the variable frequency motor, multiple mixing blades fixedly connected to the outer wall of the rotating column, and a connecting assembly being arranged at the bottom of the mixing tank.

[0006] The above technical solution enables the injection of materials when connected to an external hopper. Subsequently, under the measurement of a loss-in-weight weighing scale, the conveying auger can output the raw materials proportionally into the mixing tank. Then, the materials are uniformly mixed by the rotation of the mixing blades. This avoids the situation where the mixing ratio cannot be adjusted well in real time during material mixing, and improves the accuracy of material mixing.

An insulated pipe is connected to the top of the heating device, and a multi-hole nozzle is connected to the top of the insulated pipe. The rear end of the multi-hole nozzle passes through and is fixedly connected to the top of the front of the processing shell. A leveling component is provided on the right side of the processing shell.

[0012] The above technical solution enables the airflow to be drawn and filtered through the filter column under the start of the variable frequency fan, and then heated by the heating equipment. The heated airflow is then output through the multi-hole nozzle to achieve the purpose of drying the material. At the same time, the drying process of the material is further improved by the drive of the leveling component.

The bottom of the rectangular plate has multiple vertical grooves at equal intervals.

[0015] The above technical solution allows the rectangular plate at its left end to be displaced under the drive of the hydraulic rod, thereby enabling the material to be flattened and increasing the contact area between the material and the hot airflow.

[0016] As a further description of the above technical solution:

[0017] A control switch is fixedly connected to the right side of the base frame. The control switch is electrically connected to the servo motor, the loss-in-weight weighing scale, the frequency converter motor, the frequency converter fan, and the hydraulic rod.

[0019] As a further description of the above technical solution:

[0020] The drying and mixing mechanism also includes multiple reinforcing frames, the inner walls of which are fixedly connected to the outer wall of the processing shell, and a rubber ring is fixedly connected to the top of the outer wall of the heat-insulating pipe.

[0021] The above technical solutions improve the compressive strength of the outer wall of the casing by connecting the reinforcing frame, and enhance the protection of the connection point at the top of the insulated pipe by connecting the rubber ring.

[0022] As a further description of the above technical solution:

[0023] The mounting mechanism includes multiple mounting plates, with adjacent sides of the mounting plates fixedly connected to the bottom left and right sides of the base frame, and mounting holes provided on the top of the mounting plates.

[0024] The above technical solution facilitates flexible installation and fixation of the device by setting up the mounting plate and mounting holes.

[0025] As a further description of the above technical solution:

[0026] Multiple holes are provided on one side of the multiple mixing blades, and a sealing ring is fixedly connected to the outer wall of the injection valve.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the material is injected through the feed inlet connected to the external hopper. Under the measurement of the loss-in-weight weighing scale, the raw material is output to the mixing tank by the proportional drive conveying auger. Then, the material is evenly mixed by the rotation of the mixing blades. This avoids the situation where the mixing ratio cannot be adjusted well in real time during material mixing. With the connection of the connecting components, the mixed raw material can be conveyed into the molding machine.

[0030] 2. In this utility model, the variable frequency fan is started to draw airflow through the filter column, and then the airflow is heated by the heating equipment.

Detailed Implementation

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

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a non-woven fabric multi-material mixing and feeding system, including a base frame 1. A fixing frame 2 is fixedly connected to the top wall of the base frame 1, so that a mixing tank 3 can be supported and fixed under the connection of the fixing frame 2. The mixing tank 3 is fixedly connected inside the fixing frame 2. Multiple bolt metering mechanisms 4 are equidistantly arranged on the top of the mixing tank 3. The bolt metering mechanisms 4 are used to improve the ratio adjustment during material mixing. A drying mixing mechanism 6 is arranged at the bottom of the bolt metering mechanisms 4. The drying mixing mechanism 6 is used to improve the dryness of the material after mixing. Installation mechanisms 5 are arranged on both the left and right sides of the base frame 1. The installation mechanism 5 facilitates flexible and fixed installation of the device; the bolt metering mechanism 4 includes multiple injection pipes 401, the bottom ends of which are connected to the outer side of the top wall of the mixing tank 3. The outer wall of each injection pipe 401 is connected to an inlet 402, which connects to an external hopper for easy input of different materials. A loss-in-weight weighing scale 403 is fixedly connected to the top of each injection pipe 401. The loss-in-weight weighing scale 403 weighs the output material, thereby adjusting the feed rate and proportion of the input material. A servo motor 404 is fixedly connected inside the mixing drum 3. The output end of the servo motor 404 is fixedly connected to a conveying auger 405, which drives the conveying auger 405 to rotate, thus conveying the material into the mixing drum 3. A variable frequency motor 406 is fixedly connected to the middle of the top wall of the mixing drum 3. A rotating column 407 is fixedly connected to the output end of the variable frequency motor 406. Multiple mixing blades 408 are fixedly connected to the outer wall of the rotating column 407. The material is then mixed by the rotation of the rotating column 407, which drives the multiple mixing blades 408. A connecting assembly is provided at the bottom of the mixing drum 3. 409; The connecting assembly 409 includes an injection valve 4091. The front end of the injection valve 4091 is connected to the top rear side of the mixing tank 3. The bottom end of the mixing tank 3 is connected to a solenoid valve 4093. The solenoid valve 4093 is used to control the passage and stop of materials. The bottom end of the solenoid valve 4093 is connected to a processing shell 4094. The left end of the processing shell 4094 is connected to a conveying pipe 4095. A flange 4096 is fixedly connected to the left side of the conveying pipe 4095. The conveying pipe 4095 and the flange 4096 are used to connect to an external extraction device, thereby enabling the collection of the mixed materials.

[0040] Specifically, the fixed frame 2, which is fixedly connected to the top wall of the base frame 1, provides support for the mixing tank 3, ensuring its stable installation. The mixing tank 3, fixed inside the fixed frame 2, serves as the core container for material mixing. Multiple bolt metering mechanisms 4, evenly spaced on its top, enable precise proportioning adjustments during material mixing. The bottom ends of multiple injection pipes 401 within the bolt metering mechanisms 4 are connected to the outer side of the top wall of the mixing tank 3. The inlet 402 on the outer wall can connect to an external hopper, creating input channels for different materials and facilitating their entry into the device. A loss-in-weight weighing scale 403, fixed to the top of the injection pipes 401, accurately weighs the material output. By monitoring changes in material weight, it precisely adjusts the input material quantity and proportion. A servo motor 404, fixed inside the loss-in-weight weighing scale 403, connects to a conveying auger 405 at its output end. Driven by the servo motor 404, the auger rotates, stably conveying the metered material into the mixing tank 3. A variable frequency motor 406, fixed in the middle of the top wall of the mixing tank 3, connects to... The rotating column 407, with multiple mixing blades 408 fixed to its outer wall, rotates under the drive of the variable frequency motor 406, thoroughly mixing the material entering the mixing tank 3. The bottom connecting component 409 of the mixing tank 3 includes an injection valve 4091 connected to the top rear side of the mixing tank 3, which can be used to inject auxiliary materials or gas; a solenoid valve 4093 connected to the bottom end controls the passage and stop of materials, realizing the on / off control of material output. The bottom end of the solenoid valve 4093 is connected to the processing shell 4094, and its left end is connected to the conveying pipe 4095 and the flange 4096 fixed on the left side, for connecting to external extraction equipment to smoothly collect and transport the mixed material to the next processing stage. Simultaneously, the drying and mixing mechanism 6, located at the bottom of the bolt metering mechanism 4, can dry the material during or after mixing, improving the dryness of the mixed material. The mounting mechanisms 5 on the left and right sides of the base frame 1 provide flexible fixed installation methods for the device, allowing it to adapt to different installation environments and usage requirements.

[0041] Reference Figure 1 , Figure 2 and Figure 5The drying and mixing mechanism 6 includes a variable frequency fan 601, the rear of which is fixedly connected to the front of the processing housing 4094. A filter column 602 is connected to the top right side of the variable frequency fan 601, allowing the airflow to be filtered through the filter column 602 when the variable frequency fan 601 is started. A heating device 603 is connected to the top left side of the variable frequency fan 601, and an insulated pipe 604 is connected to the top of the heating device 603. The airflow is then heated by the heating device 603 and simultaneously transported under the insulation of the insulated pipe 604. The top is connected to a multi-hole nozzle 605, the rear end of which is connected through and fixedly connected to the front top of the processing shell 4094. Thus, the heated airflow can dry the material inside the processing shell 4094 through the multi-hole nozzle 605. A leveling component 607 is provided on the right side of the processing shell 4094. The leveling component 607 includes a hydraulic rod 6071, the outer wall of which is fixedly connected to the right side of the processing shell 4094. A rectangular plate 6072 is fixedly connected to the left end of the hydraulic rod 6071. Multiple vertical grooves 6073 are equidistantly opened at the bottom of the rectangular plate 6072.

[0042] Specifically, the variable frequency fan 601 is fixed to the front of the processing housing 4094 at the rear, forming the core power component of the drying and mixing mechanism 6. The filter column 602, connected to the top right side of the variable frequency fan 601, performs airflow filtration when the variable frequency fan 601 starts, intercepting impurities in the externally drawn airflow to ensure the cleanliness of the airflow entering the system. The heating device 603, connected to the top left side of the variable frequency fan 601, heats the filtered airflow, imparting thermal energy to it. The insulated pipe 604 connected to the top of the heating device 603 reduces heat loss during transportation, ensuring that the airflow remains relatively stable during transmission. A high-temperature, insulated pipe 604 is connected to a multi-hole nozzle 605 at its top end, which is fixed to the front top of the processing shell 4094 at its rear end. The heated and insulated airflow is evenly sprayed into the processing shell 4094 through the multi-hole nozzle 605, making full contact with the material and removing the moisture from the material, thus completing the drying process of the material inside the processing shell 4094. This effectively improves the dryness of the mixed material and ensures that the material meets the requirements for subsequent processing or use. By activating the hydraulic rod 6071, its left end can drive the rectangular plate 6072 to slide, thereby flattening the material and further improving the drying effect of the material.

[0043] Reference Figure 1 , Figure 4 and Figure 5A control switch 7 is fixedly connected to the right side of the base frame 1. The control switch 7 is electrically connected to the servo motor 404, the loss-in-weight weighing scale 403, the frequency converter motor 406, the frequency converter fan 601, and the hydraulic rod 6071 respectively. The drying and mixing mechanism 6 also includes multiple reinforcing frames 608. The inner walls of the multiple reinforcing frames 608 are fixedly connected to the outer wall of the processing shell 4094. A rubber ring 606 is fixedly connected to the top of the outer wall of the heat insulation pipe 604.

[0044] Specifically, the control switch 7, which is electrically connected to the servo motor 404, the loss-in-weight weighing scale 403, the frequency converter motor 406, the frequency converter fan 601, and the hydraulic rod 6071 respectively, enables the control switch 7 to turn the equipment on and off. Multiple reinforcing frames 608 can improve the service life of the outer wall of the processing shell 4094, and the rubber ring 606 can protect the connection at the top of the insulated pipe 604.

[0045] Reference Figure 1 and Figure 4 The installation mechanism 5 includes multiple mounting plates 501, with adjacent sides of the multiple mounting plates 501 fixedly connected to the bottom left and right sides of the base frame 1 respectively. The top of the mounting plate 501 is provided with mounting holes 502; multiple mixing blades 408 are provided with multiple holes 8 on one side, and a sealing ring 4092 is fixedly connected to the outer wall of the injection valve 4091.

[0046] Specifically, the mounting plate 501 and mounting hole 502 facilitate flexible installation of the device, and the sealing ring 4092 improves the sealing effect at the connection between the injection valve 4091 and the mixing tank 3.

[0047] Working Principle: The material input channel is established by connecting the injection pipe 401 to the external hopper via the feed inlet 402, allowing different materials to enter the device. The loss-in-weight weighing scale 403 accurately weighs the output materials. Based on the set mixing ratio, the speed of the servo motor 404 is adjusted in real time, driving the conveying auger 405 to rotate and transport the materials proportionally into the mixing drum 3. The variable frequency motor 406 in the middle of the top wall of the mixing drum 3 drives the rotating column 407 and the mixing blades 408 fixed to its outer wall to rotate, thoroughly stirring the materials inside the drum to achieve uniform mixing and prevent... The traditional method has difficulty in adjusting the mixing ratio in real time. After mixing, the injection valve 4091 can inject auxiliary materials or gas as needed. The solenoid valve 4093 controls the material output. When it is opened, the material enters the processing shell 4094 from the bottom of the mixing tank 3 through the solenoid valve 4093. Then, it is connected to the external extraction equipment through the conveying pipe 4095 and flange 4096 connected to the left end of the processing shell 4094, and the mixed material is conveyed to the molding machine and other subsequent equipment. The mounting mechanism 5 on the left and right sides of the base frame 1 can flexibly fix the device according to different installation environments and requirements.

[0048] Furthermore, after the variable frequency fan 601 is started, it draws in external airflow through the filter column 602 connected to the top right. The filter column 602 intercepts impurities in the airflow, ensuring that the airflow entering the device is clean. The purified airflow is guided by the variable frequency fan 601 and enters the heating device 603 connected to the top left. The heating device 603 heats the airflow. The heated airflow then enters the insulated pipe 604 connected to the top of the heating device 603. The insulated pipe 604 reduces heat loss from the airflow and maintains its high temperature for transport. The top of the insulated pipe 604 is connected to... A multi-hole nozzle 605 is inserted through and fixed to the front top of the processing shell 4094. High-temperature airflow is evenly sprayed into the interior of the processing shell 4094 through the multi-hole nozzle 605, making full contact with the material and removing moisture from the material to achieve drying. By activating the hydraulic rod 6071, its left end can drive the rectangular plate 6072 to slide, thereby flattening the material and further improving the drying effect. This increases the contact area between the material and the hot airflow, providing material that meets the drying requirements for subsequent processing and effectively improving the overall processing efficiency.
