Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing device technology, specifically a raw material weighing device for a cotton blending machine. Background Technology
[0002] In the cotton blending process, precise control of the proportions of various raw materials is crucial to ensuring the quality of cotton yarn. The raw material weighing device of the blending machine, as a key piece of equipment for achieving this precise control, accurately measures the weight of each type of raw material fed into the blending machine, ensuring that the blending ratio meets production requirements, thereby improving the quality stability and consistency of the cotton yarn.
[0003] Patent document CN212472021U discloses a raw material weighing device for a mixer, which solves the shortcomings of cumbersome weighing and transferring of raw materials in existing technologies. The device includes a cover with a liquid inlet pipe connected to it and a flow meter installed on the inlet pipe. A container is connected to the cover, and a rotating plate is located on the lower side of the container. A bracket is fixed to the inner wall of the cover. One end of the rotating plate is hinged to the bracket. A weighing sensor is installed on the upper side of the rotating plate, and a weighing support plate is mounted on the weighing sensor. A linear motor is rotatably connected to the cover, and the output shaft of the linear motor is hinged to the lower side of the rotating plate. This invention integrates weighing and feeding, allowing for separate feeding of liquid and solid raw materials. Operation is simple; after weighing the volumetric flow rate of the liquid and the weight of the solid, the raw materials directly enter the mixer without further transfer, reducing material loss and improving the accuracy of the mixing ratio.
[0004] However, existing raw material weighing devices for cotton blending machines generate static electricity during use when cotton rubs against pipes and conveyor belts or due to factors such as dry environment. The surface charge of the static-charged cotton creates an electric field in the surrounding space. According to the principle of electrostatic adsorption, other objects in this electric field will generate opposite charges due to electrostatic induction, thus creating electrostatic attraction between them and the cotton. This causes the cotton to adhere to these objects, affecting not only the weighing accuracy but also clogging the feed inlet and affecting the smoothness of the feeding process. Therefore, we propose a raw material weighing device for cotton blending machines. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a raw material weighing device for a cotton blending machine, thereby solving the problems mentioned in the background section.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a raw material weighing device for a cotton blending machine, comprising a material preparation box, a weighing base fixedly connected to the bottom of the material preparation box, a weighing sensor fixedly connected inside the weighing base, a feeding rack fixedly connected to one side of the material preparation box, a drive motor fixedly connected to the front of the feeding rack, conveyor rollers movably installed inside both the feeding rack and the material preparation box, a conveyor belt movably connected to the outside of the conveyor rollers, a material scraper integratedly connected to the outside of the conveyor belt, a lifting rod and a static elimination box fixedly connected to the top of the feeding rack, an air inlet opened at the top of the static elimination box, and a static eliminator and a fan fixedly connected inside the static elimination box.
[0009] Preferably, the weighing base is fixedly connected to both the front and back of the base, and the top of the base is provided with a fixing opening.
[0010] Preferably, a feeding hopper is fixedly connected to the top of the material preparation box, and the outer surface of the feeding hopper is smooth.
[0011] Preferably, a connecting plate is fixedly connected to the top of the lifting rod, and an adjusting plate is fixedly connected to one side of the connecting plate, the adjusting plate extending through the top of the unloading rack.
[0012] Preferably, the material preparation box is made of metal and has a rectangular structure.
[0013] Preferably, there are multiple material strips, all of the same size, and all of the material strips are arranged at equal intervals.
[0014] Preferably, three conveying rollers are provided, one of which is fixedly connected to the drive end of the drive motor.
[0015] (III) Beneficial Effects
[0016] This utility model provides a raw material weighing device for a cotton blending machine, which has the following beneficial effects:
[0017] (1) This type of raw material weighing device for cotton blending machine, through the installation of an electrostatic eliminator and a fan, allows the operator to add the cotton to be weighed from the feeding hopper into the preparation box. As the weight increases, the weighing sensor inside the weighing base will weigh the cotton. After weighing, when unloading, the operator starts the drive motor, which drives the conveyor roller to rotate, and the conveyor belt will start running. At this time, the material strip will pull the cotton, thereby conveying the cotton and placing it inside the cotton blending machine. As the amount of cotton decreases, the weighing value of the weighing sensor will also change. Furthermore, during the cotton conveying process, the static eliminator inside the static elimination box will operate, generating positively and negatively charged ions. At the same time, the fan will also run, blowing the positively and negatively charged ions onto the cotton to be fed and the conveying components. When these ions with opposite charges come into contact with the cotton and conveying components, they will neutralize the static charge on the surface of the objects, thereby eliminating static electricity. This prevents the cotton from sticking to these objects due to static electricity during feeding, thus improving weighing accuracy and preventing cotton accumulation from clogging the feed port and affecting the smoothness of feeding.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a raw material weighing device for a cotton blending machine, including a material preparation box 1, a weighing base 3 fixedly connected to the bottom of the material preparation box 1, a weighing sensor 301 fixedly connected inside the weighing base 3, a feeding rack 6 fixedly connected to one side of the material preparation box 1, a drive motor 7 fixedly connected to the front of the feeding rack 6, a conveyor roller 601 movably installed inside both the feeding rack 6 and the material preparation box 1, a conveyor belt 11 movably connected to the outside of the conveyor roller 601, a material scraper 12 integrally connected to the outside of the conveyor belt 11, a lifting rod 10 and a static elimination box 13 fixedly connected to the top of the feeding rack 6, an air inlet 14 opened on the top of the static elimination box 13, and a static eliminator 15 and a fan 16 fixedly connected inside the static elimination box 13.
[0025] Furthermore, mounting brackets 4 are fixedly connected to both the front and back of the weighing base 3. The top of the mounting bracket 4 has a fixing port 5. The mounting bracket 4 is positioned in the installation position, and then the bolts are inserted into the fixing port 5 to install the weighing device in the unloading position.
[0026] Furthermore, a feeding hopper 2 is fixedly connected to the top of the material preparation box 1. The outer surface of the feeding hopper 2 is smooth. By adding cotton into the feeding hopper 2, the smooth outer surface of the feeding hopper 2 allows the cotton to flow into the material preparation box 1 more effectively.
[0027] Furthermore, a connecting plate 9 is fixedly connected to the top of the lifting rod 10, and an adjusting plate 8 is fixedly connected to one side of the connecting plate 9. The adjusting plate 8 passes through the top of the feeding frame 6. By starting the lifting rod 10, the lifting rod 10 drives the adjusting plate 8 to move up and down through the connecting plate 9. At this time, the distance between the adjusting plate 8 and the conveyor belt 11 can be adjusted, thereby controlling the amount of cotton fed.
[0028] Furthermore, the material preparation box 1 is made of metal and has a rectangular structure. The material preparation box 1 made of metal is more robust and durable and less prone to damage.
[0029] Furthermore, multiple feed strips 12 are provided, all of the same size, and are arranged at equal intervals. The feed strips 12 can be used to move the cotton, so that the cotton can be fed evenly.
[0030] Furthermore, three conveyor rollers 601 are provided. One of the conveyor rollers 601 is fixedly connected to the drive end of the drive motor 7. The conveyor roller 601 can support the conveyor belt 11, so that the conveyor belt 11 can run.
[0031] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the raw material weighing device of the cotton blending machine, position the mounting bracket 4 in the installation position, and then insert the bolts into the fixing port 5 to install the weighing device at the feeding position. Then, the operator adds the cotton to be weighed from the feeding hopper 2 into the preparation box 1. As the weight increases, the weighing sensor 301 inside the weighing base 3 will weigh the cotton. After weighing, when feeding, the lifting rod 10 is activated. The lifting rod 10 drives the adjusting plate 8 to move up and down through the connecting plate 9. At this time, the distance between the adjusting plate 8 and the conveyor belt 11 can be adjusted to control the amount of cotton fed. Then, the operator starts the drive motor 7, which drives the conveyor roller 601 to rotate. The conveyor belt 11 will then start operating, and the feed bar 12 will move the cotton, thus conveying the cotton into the cotton blending machine. As the amount of cotton decreases, the weighing value of the weighing sensor 301 will also change. During the cotton conveying process, the static eliminator 15 inside the static elimination box 13 will start operating. At this time, the static eliminator 15 will generate positively and negatively charged ions. At the same time, the fan 16 will also start operating. The fan 16 will blow the positively and negatively charged ions onto the cotton to be fed and the conveying components. When these ions with opposite charges come into contact with the cotton and the conveying components, they will neutralize the static charge on the surface of the objects, thereby achieving the purpose of eliminating static electricity. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
