Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cotton bale moisture detection, specifically to an online moisture detection device for viscose staple fiber cotton bales. Background Technology

[0002] In the viscose staple fiber production process, the moisture content of cotton is a core indicator determining the product quality grade. Excessive moisture content can lead to mold growth and sticking of the cotton bales, while insufficient moisture content can cause fiber embrittlement and breakage, directly affecting the stability of subsequent processing stages such as spinning. Therefore, accurately controlling the moisture content of cotton is a critical control point in the production process. However, current mainstream testing methods in the industry have significant shortcomings: many factories rely on manual, periodic sampling and testing or expensive imported online testing equipment. The former cannot capture moisture data for each bale in real time, while the latter is too costly, neither of which can meet the demands of efficient and precise production.

[0003] Traditional manual testing requires collecting samples at fixed intervals at the baling machine entrance, then sending them to a laboratory for moisture content testing through drying and weighing. This method inherently has a lag, failing to reflect the real-time moisture status of each individual cotton bale. If moisture levels fluctuate during production, timely warnings and adjustments are difficult, easily leading to excessive moisture content in batches of cotton and a decline in product quality. Furthermore, manual sampling relies on standardized procedures; different sampling locations and quantities can cause data deviations, further affecting the accuracy of quality assessment.

[0004] As the viscose staple fiber industry develops towards refinement and efficiency, the limitations of existing testing methods are becoming increasingly prominent. Developing a cost-effective online moisture detection device for viscose staple fiber cotton bales that can achieve real-time and accurate detection has become an urgent need for the industry to improve quality control and reduce production costs. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an online moisture detection device for viscose staple fiber cotton bales, which solves the technical problem that the traditional manual detection mode in the prior art requires collecting samples at fixed intervals at the entrance of the baling machine and then sending them to the laboratory to detect the moisture content through drying, weighing and other methods, which leads to low efficiency and missed detection.

[0006] According to one aspect, at least one embodiment of this disclosure provides an online moisture detection device for viscose staple fiber cotton bales, comprising: The frame includes a frame body, a pair of notches, and a support, wherein the notches are formed at both ends of the surface of the frame body, and the support is fixed inside the notches. An outer frame and a conveying and positioning assembly, wherein the outer frame is mounted on the support, and the conveying and positioning assembly is mounted on the frame and the support; A detection component is disposed on the bracket and the outer frame; The detection component includes a transmission groove, which is horizontally opened on the surface of the support and the outer frame. The outer frame is connected to the support via a vertical linear drive. Both the support and the outer frame are L-shaped. Each transmission groove has a moving block connected via a horizontal linear drive, and each moving block is equipped with a microwave sensor.

[0007] According to another aspect, in at least one embodiment of the present invention, the conveying and positioning component includes a conveyor belt, which is installed in the frame. The surface of the conveyor belt has a plurality of rectangular openings, the opening size of which is smaller than the width of the cotton bale.

[0008] As a further technical solution, both the outer frame and the side end face of the support are equipped with fixing columns, the fixing columns are provided with side protective plates, and the side end face of the side protective plates is equipped with photoelectric sensors.

[0009] As a further technical solution, the top of the outer frame is provided with a mounting groove, a base is provided in the mounting groove, and a dual-screen display is rotatably connected in the base.

[0010] As a further technical solution, the lateral movement stroke of the moving block is matched with the opening size of the rectangular opening.

[0011] As a further technical solution, the frame is provided with several support rods, all of which are attached to the top of the conveyor belt.

[0012] As a further technical solution, a control box is installed on the outside of the frame.

[0013] As a further technical solution, the movable block located in the bracket is a frame structure wrapped around the outside of the bracket, and the microwave sensors are located at the upper end of the bracket and the bottom of the outer frame, respectively.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the detection component solves the problems of limited detection coverage and poor adaptability of traditional methods through a dual-position synchronous and flexible distance adjustment design. The L-shaped bracket and outer frame form a symmetrical layout, allowing microwave sensors to simultaneously detect the upper and lower surfaces of the cotton bale, avoiding data deviation from single-surface detection. Vertical linear drive adjusts the height of the outer frame to accommodate cotton bales of different thicknesses, ensuring the optimal detection distance between the sensor and the bale. A moving block moves laterally along the transmission groove, enabling precise detection of different areas of the cotton bale. This structure allows for the acquisition of full-surface moisture data without flipping the cotton bale, providing a comprehensive detection range and rapid adaptation to various cotton bale sizes, significantly improving detection accuracy and flexibility, and meeting the needs of online real-time detection.

[0023] like Figures 1-3 As shown, it illustrates an online moisture detection device for viscose staple fiber cotton bales according to an embodiment of this disclosure, comprising: The frame 1, a pair of notches 2, and a bracket 3 are provided. The notches 2 are formed at both ends of the surface of the frame 1, and the bracket 3 is fixed inside the notches 2. The outer frame 4 and the conveying and positioning component 6 are provided. The outer frame 4 is mounted on the support 3, and the conveying and positioning component 6 is mounted on the frame body 1 and the support 3. Detection component 5, which is disposed on the bracket 3 and the outer frame 4; The detection component 5 includes a transmission groove 5-1, which is horizontally opened on the surface of the support 3 and the outer frame 4. The outer frame 4 is connected to the support 3 by a vertical linear drive. Both the support 3 and the outer frame 4 have an L-shaped structure. Each of the transmission grooves 5-1 is connected to a moving block 5-2 by a horizontal linear drive. Each moving block 5-2 is equipped with a microwave sensor 5-3.

[0024] In some examples, in order to achieve simultaneous detection of moisture on the upper and lower surfaces of the cotton bale and flexible adjustment of the detection position, avoiding the data bias caused by traditional single-surface detection or the low efficiency of manual adjustment of the detection position, a detection component 5 was designed. This component includes a support 3 and an outer frame 4, both of which are L-shaped structures. The outer frame 4 is connected to the support 3 by a vertical linear drive, forming a symmetrical layout, corresponding to the bottom and top detection areas of the cotton bale respectively. Microwave sensors 5-3 can be installed simultaneously to detect the upper and lower surfaces of the cotton bale synchronously. The moisture data of the entire surface can be obtained without flipping the cotton bale, which greatly improves the detection efficiency.

[0025] The horizontally opened transmission groove 5-1 on the surface of the bracket 3 and the outer frame 4 provides a horizontal sliding track for the moving block 5-2. The moving block 5-2 can move laterally along the transmission groove 5-1 through horizontal linear drive, thereby driving the microwave sensor 5-3 to adjust the detection lateral position. For the moisture detection needs of different areas of the cotton bale, the sensor can be accurately aligned with the target detection point by simply adjusting the linear drive, without moving the cotton bale, thus improving the detection flexibility.

[0026] The L-shaped cantilever design provides a stable installation base for the transmission groove 5-1 and the moving block 5-2, and also avoids interference between the bracket 3 and the outer frame 4 and the cotton bale conveying, ensuring that the cotton bale can pass smoothly through the detection area. The vertical linear drive can adjust the distance between the outer frame 4 and the support 3 to adapt to the detection needs of cotton bales of different thicknesses, ensuring that the microwave sensor 5-3 always maintains the optimal detection distance from the surface of the cotton bale, avoiding signal attenuation due to excessive distance, or affecting the detection results due to pressure on the cotton bale due to excessive closeness.

[0027] During operation, the outer frame 4 adjusts its height to match the thickness of the cotton bale, and the moving block 5-2 drives the sensor to align with the detection position. The upper and lower sensors simultaneously detect moisture. The dual-frame layout enables synchronous detection, and multi-dimensional drive ensures accurate positioning. All components work together to complete the synchronous detection and position adjustment of the cotton bale, meeting the requirements for online detection.

[0028] like Figures 1-3 As shown in the figure, the conveying and positioning component 6 in this embodiment includes a conveyor belt 6-1, which is installed in the frame 1. The surface of the conveyor belt 6-1 has a plurality of rectangular openings 6-2, the opening size of which is smaller than the width of the cotton bale. The outer frame 4 and the support 3 are both equipped with fixing columns 6-3 on their side ends. The fixing columns 6-3 are provided with side protective plates 6-4. The side end face of the side protective plates 6-4 is equipped with photoelectric sensors 6-5. The top of the outer frame 4 is provided with a mounting groove 6-6, and a base 6-7 is provided in the mounting groove 6-6. A dual-screen display 6-8 is rotatably connected in the base 6-7.

[0029] In some examples, to achieve stable conveying and precise alignment of viscose staple fiber cotton bales with the detection position, and to avoid detection position deviation caused by cotton bale conveying offset, or data validity affected by asynchronous conveying rhythm and detection, a conveying and positioning component 6 was designed. This component includes a conveyor belt 6-1 installed in the frame 1 to provide continuous conveying power for the cotton bales. After the cotton bales are placed on the conveyor belt 6-1, they move uniformly to the detection area with the conveyor belt 6-1. Several rectangular openings 6-2 on the surface of the conveyor belt 6-1 have an opening size smaller than the width of the cotton bales. This allows for the provision of detection space for the bottom microwave sensor 5-3 without affecting the stability of the cotton bales support, ensuring that the sensor can directly detect the moisture at the bottom of the cotton bales and preventing the conveyor belt 6-1 from obstructing and affecting the detection accuracy.

[0030] The fixed column 6-3 on the side end face of the outer frame 4 and the support 3 drives the side protective plate 6-4 to move relative to each other. When the cotton bale moves to the detection area, the side protective plate 6-4 blocks both sides to ensure that the upper and lower surfaces of the cotton bale are precisely aligned with the corresponding microwave sensor 5-3, so as to avoid the detection data distortion caused by the cotton bale offset.

[0031] The photoelectric sensor 6-5 on the side end face of the side guard plate 6-4 can detect the position of the cotton bale in real time. When the cotton bale is detected to have reached the preset detection position, the feedback signal controls the conveyor belt 6-1 to pause or slow down, providing a stable detection window period for the detection component 5 and ensuring accurate detection data.

[0032] The base 6-7 inside the mounting slot 6-6 at the top of the outer frame 4 provides stable support for the dual-screen display 6-8. The dual-screen display 6-8 can simultaneously display the moisture data detected by the upper and lower sensors, which is convenient for operators to monitor and record in real time and improve the visualization of the detection process. The rotating connection structure inside the base 6-7 allows the display to be adjusted to suit different operating angle requirements.

[0033] During operation, the cotton bales are centered on the centering device before entering the conveyor belt. This centering device relies on roller conveyors to transport the bales, resulting in low friction. The conveyor belt (6-1) transports the bales, the photoelectric sensor (6-5) provides positioning, the side guard plate (6-4) calibrates the position, and the display shows the data. The conveyor belt (6-1) ensures continuous transport, the cylinder positioning ensures detection alignment, and all components work together to achieve stable bale transport and detection alignment, meeting the requirements of online detection.

[0034] For example, such as Figure 1 As shown, the lateral movement stroke of the moving block 5-2 matches the opening size of the rectangular opening 6-2.

[0035] In some examples, the lateral travel of the moving block 5-2 is matched with the opening size of the rectangular opening 6-2, which ensures that the bottom microwave sensor 5-3 is always within the opening range of the rectangular opening 6-2 during movement detection, avoiding the sensor being blocked by the conveyor belt 6-1, which would cause the detection signal to be interrupted or distorted.

[0036] For example, such as Figure 1 As shown, a number of support rods 7 are provided inside the frame 1, and the support rods 7 are all attached to the top of the conveyor belt 6-1.

[0037] In some examples, several support rods 7 within the frame 1 are fitted against the top of the conveyor belt 6-1, providing uniform support from below and preventing the conveyor belt 6-1 from sagging or sag due to the weight of the cotton bales. This ensures that the cotton bales remain horizontal during transport, stabilizing the distance between the bottom of the cotton bales and the bottom microwave sensor 5-3, and preventing fluctuations in detection data caused by sagging of the conveyor belt 6-1 due to inconsistent detection distance.

[0038] For example, such as Figure 1 As shown, a control box 8 is installed on the outside of the frame 1.

[0039] In some examples, the control box 8 installed on the outside of the frame 1 can centrally integrate the control modules and circuit system of the device, providing operators with a unified control interface. Through the control box 8, the speed of the conveyor belt 6-1 of the conveying and positioning component 6, the movement of the fixed column 6-3, and the linear drive stroke of the detection component 5, the start and stop of the microwave sensor 5-3, etc., can be easily adjusted to achieve coordinated operation of various components of the device.

[0040] For example, such as Figure 1 As shown, the movable block 5-2 located in the bracket 3 is a frame structure wrapped around the outside of the bracket 3, and the microwave sensor 5-3 is located at the upper end of the bracket 3 and the bottom of the outer frame 4 respectively.

[0041] In some examples, the movable block 5-2 of the frame structure in the bracket 3 is wrapped around the outside of the bracket 3, which can provide additional structural support for the movable block 5-2, enhance its stability during lateral movement, prevent the movable block 5-2 from tilting due to the weight of the microwave sensor 5-3, and ensure the accuracy of the sensor detection angle.

[0042] In practical use: The cotton bales are conveyed onto the conveyor belt via rollers from the alignment device. The control box 8 activates the device, and based on the bale thickness, the vertical linear drive adjusts the distance between the outer frame 4 and the support 3, aligning the microwave sensors 5-3 of both with the top and bottom detection areas of the bale, respectively. The viscose staple fiber cotton bales are placed on the conveyor belt 6-1, which smoothly transports the bales with the support rod 7. The rectangular opening 6-2 provides detection space for the bottom sensor. When the bale moves to the detection area, the photoelectric sensor 6-5 on the side of the side protective plate 6-4 detects its position. The horizontal linear drive moves the moving block 5-2 along the transmission groove 5-1, adjusting the lateral detection position of the microwave sensor 5-3. The upper and lower sensors simultaneously collect moisture data, and the dual-screen display 6-8 displays the detection results in real time. After detection, the conveyor belt 6-1 sends the bale to the next stage, with new bales continuously entering the detection process, achieving continuous online detection without manual sampling.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
