Description

Technical Field

[0001] This utility model relates to the field of stone paper production technology, specifically to a device for analyzing the mixing effect of stone paper raw materials. Background Technology

[0002] Stone paper, a new type of environmentally friendly material, is mainly made from raw materials such as calcium carbonate and polyethylene through mixing and extrusion molding. During the stone paper production process, the mixing effect directly affects the quality and performance of the final product. Powder mixing tanks are typically used for mixing stone paper, as these devices can uniformly mix powders of different components. However, existing stone paper raw material powder mixing tanks still have some significant problems in assessing the mixing effect after mixing, especially in evaluating material hierarchy and mixing uniformity.

[0003] Currently, methods for detecting mixing effects mainly rely on traditional visual sampling or post-sampling analysis using equipment. Traditional visual sampling relies on human experience to judge the uniformity of material mixing, typically involving sampling at the opening of the mixing tank and observing the appearance or color distribution of the materials. While this method is simple to operate and requires no complex equipment, its results depend on human judgment, are highly subjective, and cannot accurately assess the material distribution at different levels and locations during the mixing process. Since stone paper raw material mixing tanks are typically large, uneven material distribution between layers or insufficient mixing in certain areas may occur during the mixing process. Visual inspection can only provide a rough overall assessment and is insufficient to identify localized uneven mixing problems.

[0004] To improve the accuracy of mixing, some factories employ equipment sampling and testing methods, extracting a certain amount of material samples for subsequent analysis. These devices typically utilize optical, ultrasonic, or electromagnetic technologies to analyze the samples and assess the homogeneity of the materials. While this method offers higher accuracy than visual inspection, several problems remain. First, sampling itself has limitations, usually only obtaining material information from a localized area and failing to comprehensively reflect the mixing effect throughout the entire mixing tank. Second, the sampling process is cumbersome, involving multiple steps including sample extraction, processing, and analysis, increasing the complexity and time cost of the production process.

[0005] In summary, existing stone paper raw material powder mixing tanks typically rely on visual sampling or equipment testing after mixing to obtain the mixing effect analysis results. However, this sampling analysis is not accurate enough for detecting the mixing effect of materials at different levels within the tank, and the sampling and testing process is cumbersome. In view of the above problems, a stone paper raw material mixing effect analysis device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a device for analyzing the mixing effect of stone paper raw materials, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stone paper raw material mixing effect analysis device, including a mixing tank, wherein an analyzer is assembled on the outside of the mixing tank;

[0008] The analyzer is equipped with a completely transparent cover inside, and a telescopic plate that can move in and out is installed inside the transparent cover. The telescopic plate can push the contents of the mixing tank back into the mixing tank or release them into the transparent cover.

[0009] A signal transmitter and a signal receiver are arranged opposite each other on the outside of the transparent cover. The signals transmitted and received between the signal transmitter and the signal receiver will pass through the transparent cover during detection.

[0010] Preferably, the mixing tank includes a tank body, the outside of which is fitted with a fixing belt, and a vibrator is uniformly fitted on the outside of the fixing belt.

[0011] Preferably, the top of the tank is fitted with a flange for assembly with a top stirring device.

[0014] Preferably, the end of the fixing frame is equipped with a positioning component, and the end of the positioning component is provided with a slot.

[0015] Preferably, a fixing claw is welded to the end of the telescopic plate, and the fixing claw passes through the inside of the slot.

[0016] Preferably, the front end of the fixing frame is welded with a hinge joint.

[0017] Preferably, the bottom of the tank is provided with a discharge port, the front end of the hinge joint is hinged with a bottom cover, the bottom of the tank is welded with a screw button around the discharge port, the screw button has a thread inside, the bottom cover is fixed with connecting claws, and the top of the bottom cover can seal the inside of the discharge port.

[0018] Preferably, the travel of the internal slot of the transparent cover is greater than the maximum outward movement of the telescopic plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up a mixing tank with an analyzer. After mixing is completed, the external driving device drives the telescopic plate to move outward inside the slots inside the through groove, the fixed frame, and the card slot. When the telescopic plate moves to the maximum distance, the inside of the transparent cover becomes a cavity structure. Then, the contents inside the mixing tank enter the slots inside the through groove, the fixed frame, and the card slot. The vibration of the auxiliary vibrator drives the contents to move. When the contents completely fill the cavity, the signal transmitter and the signal receiver are activated. By comparing the transmission and reception of the signals, the signal attenuation in different areas is detected, and the analysis result of the mixing effect is finally obtained. Then the telescopic plate is reset, pushing the contents back into the tank. This effectively solves the problem that the existing stone paper raw material powder mixing tanks generally obtain the mixing effect detection and analysis results by visual sampling or by equipment detection after sampling after mixing. The sampling analysis is not accurate enough for detecting the mixing effect of materials at different levels inside the tank, and the sampling and detection process is cumbersome.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figure 1-8 This utility model provides a technical solution: a stone paper raw material mixing effect analysis device, including a mixing tank 1, and an analyzer 2 is assembled on the outside of the mixing tank 1;

[0031] The analyzer 2 has a completely transparent cover 23 inside, and the transparent cover 23 is equipped with a telescopic plate 25 that can move inward and outward. The telescopic plate 25 can push the contents of the mixing tank 1 back into the mixing tank 1 or release them into the transparent cover 23.

[0032] A signal transmitter 26 and a signal receiver 27 are arranged opposite each other on the outside of the transparent cover 23. The signals transmitted and received between the signal transmitter 26 and the signal receiver 27 will pass through the transparent cover 23 during detection.

[0033] This invention provides a mixing tank 1 equipped with an analyzer 2. After mixing, an external drive device moves a telescopic plate 25 outward from the slots inside the through groove 17, the fixing frame 21, and the slot 22. When the telescopic plate 25 reaches its maximum distance, the interior of the transparent cover 23 becomes a cavity structure. Subsequently, the contents of the mixing tank 1 move outward into the slots inside the through groove 17, the fixing frame 21, and the slot 22. The vibration of the auxiliary vibrator 13 drives the contents to move. When the contents completely fill the cavity, the signal transmitter 26 and the signal receiver 27 are activated. By comparing the transmission and reception of signals, the signal attenuation in different areas is detected, and the final analysis result of the mixing effect is obtained. Then, the telescopic plate 25 is reset, pushing the contents back into the tank 1. This effectively solves the problem that existing stone paper raw material powder mixing tanks, after mixing, generally rely on visual sampling or equipment testing to obtain the mixing effect analysis results. The resulting sampling analysis is not accurate enough for detecting the mixing effect of materials at different levels inside the tank, and the sampling process is cumbersome.

[0034] Specifically, the mixing tank 1 includes a tank body 11, and a fixing belt 12 is mounted on the outside of the tank body 11. Vibrators 13 are evenly mounted on the outside of the fixing belt 12. The vibrators 13 are mainly used to improve the flowability of materials after the telescopic plate 25 moves outward, so as to ensure that the materials can fill the cavity of the transparent cover 23 through the slots 17, the inside of the fixing frame 21 and the inside of the slot 22. The installation position and number of vibrators 13 need to be determined according to the production capacity and flow direction of the mixing tank 1. They are generally set in the middle and lower part of the mixing tank 1. In addition to assisting the materials to fill the inside of the transparent cover 23 to achieve a sampling function, the vibrators 13 can also continuously start the mixing of auxiliary materials during the mixing process.

[0035] Specifically, the top of the tank body 11 is equipped with a flange 16 for assembly with the top stirring equipment, and the top of the tank body 11 is combined with the top cover or stirring mechanism of the tank body.

[0036] Specifically, a through groove 17 is provided on the side surface of the tank body 11, and a base is provided at the bottom of the tank body 11 according to the actual situation and the required height, for the purpose of making a complete set of mixing tank 1, and also to leave space for the discharge port to reserve sufficient discharge space.

[0037] Specifically, the analyzer 2 includes a mounting bracket 21, the front end of which is fixedly installed on the outer wall of the tank 11, and the inner side of the mounting bracket 21 is provided with a slot corresponding to the through groove 17. The slot corresponds to the through groove 17. The end of the mounting bracket 21 is provided with a slot 22, and the transparent cover 23 is assembled inside the slot 22.

[0038] The transparent cover 23 is preferably made of a wear-resistant transparent material. Depending on the signal medium and conduction mechanism of the signal transmitter 26 and the signal receiver 27, appropriate materials need to be selected accordingly, such as rubber materials that are conducive to ultrasonic detection.

[0039] Specifically, the end of the fixed frame 21 is equipped with a positioning component 24, and the end of the positioning component 24 is provided with a slot. The outer side of the telescopic plate 25 is equipped with an external transmission device. The transmission device can drive the telescopic plate 25 to move vertically to the inside or outside of the tank 11. The material structure of the telescopic plate 25 needs to be made of a relatively high-strength material.

[0040] The overall width of the slots inside the through slot 17, the fixing bracket 21, and the card slot 22 should be such that the spacing is as small as possible, provided that the strength of the telescopic plate 25 does not bend or deform during the pushing process, which is conducive to signal penetration and analysis.

[0041] Specifically, the telescopic plate 25 has a fixing claw welded to its end. The fixing claw passes through the inside of the slot. The strength of the telescopic plate 25 mainly refers to its hardness.

[0042] Specifically, a hinge joint 28 is welded to the front end of the fixing bracket 21. The hinge joint 28 is hinged to the extension rod at the bottom end of the bottom cover 18. In use, the bottom cover 18 can be locked by passing a bolt through the end of the connecting claw 14 and screwing it into the center of the screw button 15. In addition to the installation method of the connecting claw 14, the bottom cover 18 can also be locked by a bolt structure.

[0043] Specifically, the tank body 11 has a discharge port at the bottom end, the front end of the hinge joint 28 is hinged to the bottom cover 18, the bottom of the tank body 11 is welded around the discharge port with a screw button 15, the screw button 15 has a thread inside, the bottom cover 18 is fixed with a connecting claw 14, and the top of the bottom cover 18 can seal the inside of the discharge port.

[0044] Specifically, the travel of the internal slot of the transparent cover 23 is greater than the maximum outward movement of the telescopic plate 25.

[0045] The specific usage methods of the signal transmitter 26 and the signal receiver 27 include the following:

[0046] 1. Light intensity detection method

[0047] Principle: The uniformity of mixing is determined by detecting the degree of attenuation of light intensity by the powder.

[0048] The equipment used includes: LED light source, photosensitive sensor (such as photodiode or phototransistor), and signal processing unit.

[0049] Distribution of transmitters and receivers:

[0050] Working process: The light source and photosensitive sensors are linearly distributed along the width of the transparent cover 23 inside the inner grooves of the signal transmitter 26 and the signal receiver 27. The preferred installation position of the sensors is one-to-one correspondence. In use, the light source emits a stable beam of light that passes through the powder, and the receiver is located on the other side of the beam, illuminating the powder along the length of the transparent cover to form a scanning state, or all of them can be turned on and all of them can be received simultaneously to analyze the final occlusion distribution.

[0051] Scanning method: Each light source and sensor pair performs synchronous scanning to collect data from multiple points, and generates a continuous light intensity distribution image through interpolation algorithm.

[0052] Analysis process:

[0053] When a light beam emitted from a light source passes through powder, it attenuates due to variations in powder distribution. A photosensor receives the intensity signal of the transmitted light. When the powder is uniformly mixed, the change in light intensity is minimal; however, if the powder is unevenly mixed, the attenuation value will differ significantly between different areas.

[0054] The scanned image: A grayscale image is generated by interpolating the light intensity at multiple detection points. The grayscale value represents the degree of light intensity attenuation. The brightness difference of the image can show the mixing effect of different areas. The light intensity data is converted into a grayscale image using image processing software. The grayscale value is directly related to the light intensity. The generated image presents an effect similar to an X-ray scan and can be printed out.

[0055] 2. Laser scattering analysis method

[0056] Principle: The scattering characteristics of laser light in powder are used to detect particle distribution and uniformity.

[0057] The equipment used includes: a low-power laser emitter, a photomultiplier tube or CMOS camera, and an image processing unit.

[0058] Distribution of transmitters and receivers:

[0059] Working process: The laser emitter and receiver perform point scanning along the horizontal or vertical direction of the transparent cover 23. The robotic arm controls the laser emitter to scan different positions inside the transparent cover point by point. Each scan collects scattered light data at a specific position. The robotic arm structure is driven by a vertical linear guide rail with a drive structure. The robotic arm is mounted inside the grooves of the signal transmitter 26 and the signal receiver 27, moving synchronously. During use, vertical scanning of the outside of the transparent cover 23 is achieved by raising and lowering the arm.

[0060] Scanning method: The laser emits light point by point, and the receiver receives the scattered light signal at each point, forming a scattered light pattern covering the entire transparent cover.

[0061] Analysis process:

[0062] The laser beam interacts with particles in the powder; the distribution, size, and morphology of the particles affect the scattering angle and intensity of the light. The scattered light is captured by a receiver to generate a scattering image.

[0063] The scanned image is a two-dimensional image of scattered light distribution, representing the light intensity distribution in different regions. The scattered intensity data is mapped to color values ​​to generate a heatmap (color image), which is then visualized using image processing software. The generated image resembles a microscopic scan and can be printed to observe the uniformity of the mixture.

[0064] 3. Multispectral transmission analysis method

[0065] Principle: The mixing of powders is analyzed by examining the transmission characteristics of light at different wavelengths.

[0066] The equipment used includes: multispectral LED light source, spectral receiver (spectrometer), and data analysis unit.

[0067] Distribution of transmitters and receivers:

[0068] Working process: Multi-wavelength light sources and receivers are evenly arranged along the width of the transparent cover 23 and assembled inside the grooves of the signal transmitter 26 and signal receiver 27, forming a linear distribution. The light sources emit light of multiple wavelengths, which are then transmitted through the powder and the intensity of the transmitted light is detected by the receiver.

[0069] Scanning method: Each time the light source emits light of one wavelength, the transmitted light data is received by the receiver to form a dataset of correlation between wavelength and light intensity.

[0070] Analysis process:

[0071] When light of various wavelengths passes through powder, different wavelengths of light undergo different absorption and scattering phenomena within the powder. The composition, size, and uniformity of the powder lead to variations in the intensity of transmitted light of different wavelengths.

[0072] The scanned image: The generated image is based on multispectral data, mapping the transmission intensity of each wavelength to a different color. The final synthesized image is a pseudo-color image. Image processing software maps the transmission data of each wavelength to the corresponding color, generating a color image similar to thermal imaging, which is then output and printed.

[0073] 4. Ultrasonic transmission analysis method

[0074] Principle: The propagation characteristics (velocity, attenuation) of ultrasound in powder are used to analyze particle distribution and mixing.

[0075] The equipment used includes: ultrasonic transmitter, ultrasonic receiver, and signal analyzer.

[0076] Distribution of transmitters and receivers:

[0077] Working process: The ultrasonic transmitter and receiver scan layer by layer along the vertical direction of the transparent cover 23 by means of lifting and lowering scanning distribution. Each scan will collect ultrasonic propagation data of a specific height layer. The ultrasonic transmitter and ultrasonic receiver are assembled inside the grooves of the signal transmitter 26 and signal receiver 27 by vertical linear guide rails, and synchronous vertical displacement completes the entire scanning process.

[0078] Scanning method: The ultrasonic transmitter emits pulses at different levels, and the receiver receives the return signal at the corresponding position, recording data layer by layer.

[0079] Analysis process:

[0080] The propagation speed and attenuation characteristics of ultrasonic signals in powders are affected by the powder density, particle size, and distribution. A density distribution map of the powder is generated based on the time delay and intensity of the received signal.

[0081] The scanned image generates a two-dimensional distribution map of the ultrasonic signal, reflecting the density changes of the powder at different layers. The propagation time and intensity of the ultrasonic signal are converted into a bitmap, forming a two-dimensional image similar to medical ultrasound imaging. High-contrast images are generated using image processing software for easy observation or printing.

[0082] 5. Electromagnetic signal detection method

[0083] Principle: The mixing state is analyzed by utilizing the absorption and reflection characteristics of powder to high-frequency electromagnetic waves.

[0084] The equipment used includes a high-frequency electromagnetic wave transmitter, a receiving antenna, and a spectrum analyzer.

[0085] Distribution of transmitters and receivers:

[0086] Working process: The electromagnetic wave transmitter and receiver are distributed at points and surround the transparent cover using a rotating arm or sliding system to detect the electromagnetic wave reflection and absorption of the powder point by point. The electromagnetic wave transmitter and receiver are assembled inside the grooves of the signal transmitter 26 and the signal receiver 27 through vertical linear guide rails, and the entire scanning process is completed by synchronous vertical displacement.

[0087] Scanning method: The transmitter periodically emits electromagnetic waves, and the receiver records the signal changes at each location to form complete scan data.

[0088] Analysis process:

[0089] The uniformity of powder mixing is analyzed by examining changes in its absorption and reflection characteristics of electromagnetic waves. Electromagnetic wave signals are processed using a spectrum analyzer to obtain the material distribution characteristics in different regions.

[0090] The scanned images: The intensity and reflection data of the spectrum will be converted into a two-dimensional image to represent the distribution of the material. The spectrum data will be converted into a pseudo-color image, and different frequency intensities will be displayed through color changes. Finally, an image similar to thermal imaging will be generated, which is convenient for observation or printing.

[0091] The above methods are just a few analysis methods for signal transmitter 26 and signal receiver 27. In actual use, any method that can change the signal after passing through the transparent cover 23 with material through signal attenuation, scattering, etc., and is easy to observe is acceptable.

[0092] A high-intensity lighting fixture can also be installed at one end of the signal transmitter 26, and a vertically displaced industrial camera can be installed inside the signal receiver 27. The image is transmitted to the computer by uniformly displacing the camera to capture the image. The results are output through observation or intelligent analysis to analyze the type and distribution of raw material particles and achieve the effect of detection and analysis.
