Description

Technical Field

[0001] This utility model relates to the field of spinning machine equipment technology, specifically to an online yarn quality detection structure for a roving frame. Background Technology

[0002] A roving frame is a type of spinning machinery mainly used to process cotton fibers or other fibers into roving. The main functions of a roving frame are drafting and twisting, and winding the roving into a certain package to meet the processing requirements of a ring spinning frame. It can turn fiber slivers into roving, providing the necessary raw materials for subsequent spinning processes.

[0003] Existing roving frames lack online yarn quality monitoring structures. For example, a roving frame disclosed in application number CN201821337090.3 is used. During the production process, yarn quality is affected by various factors, such as raw material quality, process parameters, and equipment status. Without an online monitoring structure, it is impossible to monitor and provide feedback on yarn quality in real time, which may lead to fluctuations in yarn quality and affect the quality of the final product. In the production process, roving frames without online monitoring structures may need to monitor yarn quality through manual sampling inspection. This method is not only inefficient but may also fail to fully reflect the true quality of the yarn. Once yarn quality problems occur, a large amount of rework and repair work may be required, thereby increasing production costs. Roving frames without online monitoring structures cannot detect and correct yarn quality problems in a timely manner during production, which may lead to interruptions and delays in the production process. At the same time, manual sampling inspection also requires a certain amount of production time, further reducing production efficiency.

[0004] Therefore, it is necessary to invent an online yarn quality detection structure for roving frames to solve the above problems. Utility Model Content

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The online yarn quality inspection structure of this roving frame features identical top and bottom inspection frames, both capable of inspecting yarn. The top inspection frame has a moving groove in the center of its bottom surface, with a reciprocating screw mounted in the middle of the groove. A moving seat surrounds the groove, and a camera is mounted at the bottom of the moving seat to capture and analyze images of the yarn. A moving block is positioned between the inner center of the moving seat and the reciprocating screw, enabling the moving seat to move back and forth on the screw, thus achieving comprehensive yarn inspection. A control box is mounted on the upper side of one side of the side frame to control the operation of the entire inspection structure, while a data display is mounted on the upper side of the other side to display inspection results and related information.

Cotton to be spun is placed on the feeding seats 101. A yarn roller 2 is arranged on the rear top side of the spinning frame frame 1, and a rear roller is arranged above the yarn roller 2. The frame 3, yarn roller 2 and rear roller frame 3 are each provided with two sets. The transmission mechanism 4 is installed on one side of the yarn roller 2 and rear roller frame 3 and is used to drive the yarn roller 2 and rear roller frame 3 to rotate. The transmission mechanism 4 is installed at one end of the yarn roller 2 and rear roller frame 3. The front roller frame 5 is installed in the middle of the front side of the spinning machine frame 1. Side plate frames 6 are fixedly installed on both sides of the outer wall of the spinning machine frame 1. The control box 601 is installed on the upper side of one side of the outer wall of the side plate frame 6, and the data display 602 is installed on the upper side of the other side of the outer wall of the side plate frame 6.

[0025] A top inspection frame 7 is installed on the top of the side panel frame 6, and a bottom inspection frame 8 is installed directly below the top inspection frame 7. The yarn to be woven is drawn to the two sets of yarn rollers 2 and the rear roller frame 3 above by two guide rods. The yarn passing over the surface of the yarn rollers 2 and the rear roller frame 3 passes between the top inspection frame 7 and the bottom inspection frame 8, and the yarn is finally drawn and wound around the front roller frame 5. The top inspection frame 7 and the bottom inspection frame 8 have the same structure. A moving groove 701 is opened in the middle of the bottom surface of the top inspection frame 7, and a reciprocating screw 702 is installed in the middle of the moving groove 701. The top detection frame 7 is surrounded by a movable base 703. A detection camera 704 is installed at the bottom of the movable base 703. A movable block is set between the middle of the inner side of the movable base 703 and the reciprocating screw 702. Slider 705 is installed on both sides of the inner wall of the movable base 703.

Rotating shafts 707 are set between the two ends of the reciprocating screw 702 and the movable grooves 701. A motor 708 is connected to the outer side of one end of the reciprocating screw 702. The motor 708 is located at one end of the outer wall of the top detection frame 7.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5For this type of roving frame's online yarn quality detection structure, during use, the cotton material to be spun is first placed on the feeding seat 101. Pulled by the first guide rod 102 and the second guide rod 103, the cotton material is fed between the yarn roller 2 and the rear roller frame 3. The transmission mechanism 4 drives the yarn roller 2 and the rear roller frame 3 to rotate, thereby achieving the spinning treatment of the cotton material. The yarn, after surface treatment on the yarn roller 2 and the rear roller frame 3, passes between the top detection frame 7 and the bottom detection frame 8. Both the top detection frame 7 and the bottom detection frame 8 are equipped with detection cameras 7. 04. Used to capture image information of yarn, the detection camera 704 can move back and forth along the length of the yarn under the drive of the reciprocating screw 702 via the moving base 703, so as to realize the comprehensive detection of the yarn. The image information captured by the detection camera 704 is transmitted to the image processing unit in the control box 601 for processing. The image processing unit analyzes the image and extracts key parameters such as yarn diameter and uniformity. The processed data is displayed in real time through the data display 602, which makes it convenient for operators to monitor the quality of the yarn.

[0028] When using this device, turn on the power to the control box 601, start the motor 708, and the reciprocating screw 702 will start to rotate, thereby driving the detection camera 704 to move back and forth. Start the transmission mechanism 4, so that the yarn roller 2 and the rear roller frame 3 will start to rotate, and the spinning process will begin. Place the cotton material to be spun on the feeding seat 101, ensuring that the cotton material is flat and the tension is moderate. The operator can monitor the quality parameters of the yarn in real time through the data display 602, such as diameter and uniformity. If the yarn quality is found to be unsatisfactory, the machine can be stopped immediately for inspection and adjustment of the spinning parameters. Regularly inspect and maintain the equipment to ensure the normal operation and accuracy of each component. Clean the detection camera 704 and lens to avoid dust and impurities affecting the detection effect. This online yarn quality detection structure for roving frames, through the high-precision detection camera 704 and image processing technology, realizes real-time monitoring and precise control of yarn quality, providing the textile industry with an efficient and reliable means of yarn quality detection.
