Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, in particular to a foreign fiber and dust separator. Background Art

[0002] A foreign matter separator is a device specifically designed to separate and remove foreign matter from textiles. Leveraging cutting-edge technology and precise sensors, it can efficiently identify and remove foreign matter from textile materials. This equipment is typically used in the pre-processing stage of the textile industry to ensure textile quality and purity. The core function of a foreign matter separator is to utilize high-speed cameras and image processing technology to detect foreign matter and fine dust in textile materials in real time. The device then automatically activates the appropriate separation mechanism, such as air jets or mechanical grippers, to remove these foreign particles from the textile material. The entire process is highly automated, significantly improving production efficiency and product quality. With accumulated experience and continuous technological optimization, existing foreign matter separators ensure the high quality and purity of textiles through their efficient and precise separation technology.

[0003] Deficiencies of existing foreign fiber and dust separators: Current foreign fiber separation technology generally relies on the combination of high-speed cameras and air flow injection technology. However, in a large-scale production environment, high-speed cameras must capture and process each frame of the image during the detection process, and the image processing algorithm also requires time to analyze and make judgments, which leads to a certain delay in the entire detection and separation process. Especially when processing a large amount of high-resolution image data, the processing speed may be limited, thereby affecting the overall separation efficiency. In addition, in order to achieve this process, high-quality high-speed cameras, image acquisition cards, powerful computers and other hardware equipment must be used, and complex image processing algorithms and software systems must be developed. These factors jointly push up the cost of the equipment. The complexity of the system also means that professional technicians are required for the installation, debugging and maintenance of the equipment, which not only increases labor costs but also increases the difficulty of maintenance. Utility Model Content

[0005] The centrifugal separation structure includes a placement cylinder rotatably connected to the opposite sides of the two support plates through bearings, two meshing wheels assembled at the edges of the two ends of the outer wall of the placement cylinder, and a servo motor assembled on the top of the support plate. The output end of the servo motor is fixedly connected to a transmission wheel, and the side of the transmission wheel away from the servo motor is fixedly connected to the output wheel through a connecting rod. The transmission wheel and the output wheel are respectively meshed with the two meshing wheels. A discharge pipe is provided in the middle of the placement cylinder, and a plurality of pneumatic valves are provided on the inner wall of the discharge pipe.

[0006] Preferably, it also includes a mounting base located at the bottom of the two support plates, and the foreign fiber collection structure includes a collection tube fixedly installed on the top surface of the mounting base and sleeved on the outside of the placement tube, and a connecting pipe connected to the collection tube is provided on the back of the collection tube.

[0010] Preferably, the discharge pipe is configured to be hollow and the right end is fixedly connected to the inner wall of the discharge pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model combines a centrifugal separation structure with a foreign fiber collection structure, so that foreign fibers with larger mass and higher density are subjected to a greater force under the action of centrifugal force, and are thereby thrown to the outside of the cylinder and fall into the collection cylinder. At the same time, fibers with lighter mass and lower density are subjected to less centrifugal force and are closer to the rotation center, making it easier to be sucked out through the discharge pipe later. The equipment can operate continuously and effectively process a large amount of cotton fiber mixtures, making it very suitable for large-scale production environments. It has a good separation effect on foreign fibers of different types, sizes and shapes. In addition, since the equipment mainly adopts a mechanical structure, its maintenance work mainly focuses on the mechanical components.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the present invention provides a foreign fiber and dust separator, comprising two symmetrically distributed support plates 1, a centrifugal separation structure 2 located in the middle of the two support plates 1, and a foreign fiber collecting structure 3 located outside the centrifugal separation structure 2;

[0022] The centrifugal separation structure 2 includes a placement cylinder 21 rotatably connected to the opposite sides of the two support plates 1 through a bearing, two meshing wheels 22 assembled at the edges of the two ends of the outer wall of the placement cylinder 21, and a servo motor 23 assembled on the top of the support plate 1. The output end of the servo motor 23 is fixedly connected to a transmission wheel 24, and the side of the transmission wheel 24 away from the servo motor 23 is fixedly connected to an output wheel 26 through a connecting rod 25. The transmission wheel 24 and the output wheel 26 are respectively meshed with the two meshing wheels 22. A discharge pipe 27 is provided in the middle of the placement cylinder 21, and a number of pneumatic valves are provided on the inner wall of the discharge pipe 27.

[0023] The above scheme is adopted: by combining the centrifugal separation structure 2 and the foreign fiber collection structure 3, the foreign fibers with larger mass and higher density are subjected to greater force under the action of centrifugal force, and are thereby thrown to the outside of the cylinder and fall into the collection cylinder 31. At the same time, the fibers with lighter mass and lower density will be closer to the center of rotation due to the smaller centrifugal force, which is convenient for subsequent suction through the discharge pipe 27. The equipment can operate continuously and effectively process a large amount of cotton fiber mixtures. It is very suitable for large-scale production environments. It has a good separation effect on foreign fibers of different types, sizes and shapes. In addition, since the equipment mainly adopts a mechanical structure, its maintenance work is mainly concentrated on the mechanical parts. For technicians who master the mechanical principles, maintenance is relatively easy.

[0024] like Figures 1 to 6 As shown, it also includes a mounting base plate 4 located at the bottom of the two support plates 1, and the foreign fiber collection structure 3 includes a collecting cylinder 31 fixedly installed on the top surface of the mounting base plate 4 and sleeved on the outside of the placement cylinder 21. The back of the collecting cylinder 31 is provided with a connecting pipe 32 connected thereto, and the inner wall of the placement cylinder 21 is provided with equidistantly distributed separation grooves 213, and the separation grooves 213 are all distributed in a circular array.

[0025] The above solution is adopted: the transmission wheel 24 is driven by the rotation of the servo motor 23, and then acts on the output wheel 26 through the connecting rod 25 to rotate it. The coordinated rotation of the transmission wheel 24 and the output end drives the rotation of the two meshing wheels 22, thereby rotating the placement cylinder 21. The centrifugal force generated during the high-speed rotation is based on the formula F=mω²r, where F represents the centrifugal force, m represents the mass of the object, ω represents the angular velocity, and r represents the rotation radius. It can be found that under the conditions of the same angular velocity and rotation radius, the centrifugal force exerted on objects of different masses is different. This principle causes the foreign fibers to be subjected to a greater force under the action of centrifugal force, thereby being thrown to the outside of the centrifugal device, closer to the wall of the device. Relatively speaking, fibers with lighter mass and lower density are subjected to less centrifugal force, so they will be closer to the center of rotation.

[0026] like Figures 1 to 6 As shown, the collecting cylinder 31 is located in the middle of the two meshing wheels 22 and the inner wall of the collecting cylinder 31 is provided with a groove connected to the placing cylinder 21. The left and right ends of the placing cylinder 21 are respectively connected to the feed pipe 211 and the discharge pipe 212.

[0027] The above solution is adopted: the feed pipe 211 and the discharge pipe 212 work together to introduce the fiber material into the barrel and ensure that the fibers are effectively separated in the barrel. Among them, the main responsibility of the feed pipe 211 is to transport the fiber material from the outside to the collecting barrel 31 to ensure that the fibers enter the barrel smoothly.

[0028] like Figures 1 to 6As shown, the discharge pipe 27 is configured to be hollow and the right end is fixedly connected to the inner wall of the discharge pipe 212.

[0029] The above solution is adopted: by fixing the position of the discharge pipe 27, when the fiber inside the cylinder 21 needs to be taken out later, it is only necessary to connect the discharge pipe 27 to the external extraction pump and open the pneumatic valve at the same time. In this way, the fiber can enter the discharge pipe 27 through the valve and then be extracted.

[0030] The working principle and use process of this utility model:

[0031] First, the fiber material to be separated is input into the placement barrel 21 through the feed pipe 211, and the servo motor 23 is started to drive the transmission wheel 24 to rotate. The transmission wheel 24 rotates the output wheel 26 through the connecting rod 25. The transmission wheel 24 and the output wheel 26 work together to drive the two meshing wheels 22 to rotate, thereby causing the placement barrel 21 to rotate at high speed. Under the action of the centrifugal force generated by the high-speed rotation, the foreign fibers with larger mass and higher density are thrown to the outside of the placement barrel 21 by a greater force and fall into the collection barrel 31. The fibers with lighter mass and lower density are closer to the rotation center due to the smaller centrifugal force. The collection barrel 31 is located in the middle of the two meshing wheels 22 and receives the thrown foreign fibers through the separation groove 213. At this time, the foreign fibers enter the collection barrel 31 through the separation groove 213 and can be subsequently extracted through the connecting pipe 32. When the fibers in the placement barrel 21 need to be removed, the discharge pipe 27 is connected to the external extraction pump, and the pneumatic valve on the inner wall of the discharge pipe 27 is opened. The fibers enter the discharge pipe 27 through the valve and are then extracted.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
