Description

Technical Field

[0001] The present invention relates to the field of raw silk fineness inspection, in particular to a suspended real-time broken silk detection device. Background Art

[0002] Raw silk fineness testing is a key quality control measure for raw silk. Its primary purpose is to detect variations in the thickness of the silk strands. The results directly impact the grading of the entire batch of raw silk. Raw silk fineness testing follows the procedures of the current standard GB / T 1798-2008, "Test Methods for Raw Silk." For each batch of raw silk, fineness testing is performed on 50 spindles and 200 skeins of fine yarn (each spindle produces four skeins). Each skein is wound 100 times (turns) on a fineness machine with a frame circumference of 1.125m. The fineness of each skein is then measured using a fineness meter. Because each batch of silk requires a large number of samples, broken yarns are unavoidable during the winding process. Conventional methods address this by increasing the number of test groups and removing broken yarn samples. However, this method is inefficient and wastes material.

[0003] A new solution to the problem of broken silk has also been proposed in the prior art. It only requires the samples of broken silk to be supplemented, and there is no need to increase the number of inspection groups. However, the broken silk sensors currently used in the textile industry can only detect whether a broken silk has occurred, and cannot send a broken silk signal in real time. When a broken silk occurs, the broken silk sensor needs to delay for a period of time before sending a broken silk signal, and cannot accurately record the number of times the silk has been wound when it breaks. Therefore, it is necessary to design a broken silk detection device that can accurately record the position of the broken silk in the raw silk, and perform real-time detection of the broken silk fault. When the detection device detects a broken silk, it performs a subsequent 100-round supplement operation based on the recorded broken silk position to ensure the accuracy of the length of each skein of raw silk. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of existing broken wire sensors, such as delayed signal transmission and inaccurate detection, and to provide a suspended real-time broken wire detection device that can transmit a broken wire signal without delay after the wire breaks, has a simple structure, and is low in cost. To this end, the present invention adopts the following technical solutions:

[0005] A suspended real-time broken wire detection device is characterized in that it includes a suspended sensing component, a wire guide porcelain eye is provided on the suspended sensing component, the suspended sensing component is movably mounted in a fixed frame, a sensing head is provided at the lower end of the fixed frame, and a space for the suspended sensing component to slide up and down is provided; a photoelectric sensor is provided below the space; a first wire guide component and a second wire guide component are provided in front and behind the suspended sensing component, respectively, so that the suspended sensing component can be supported by the raw silk passing through the first wire guide component, the suspended sensing component and the second wire guide component and be in a suspended state, and when the raw silk breaks, the component loses support and falls to cooperate with the photoelectric sensor.

[0006] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these further technical solutions in combination:

[0007] The suspended real-time broken wire detection device of the present invention can be configured as a module and embedded in front of a winding frame of a fineness testing device.

[0008] The suspended induction component adopts a sheet structure, and a slit gap is provided in the fixing frame for guiding the sheet structure to slide up and down. The fixing frame is also provided with a detection square hole for the guide wire porcelain eye to move up and down.

[0009] The fixing frame includes a base frame, a bracket plate, a pressure plate and a pad that are integrated with the base frame. The pad is arranged between the bracket plate and the pressure plate. The pad is in a downward opening form, and the slit-type gap is provided between the bracket plate and the pressure plate through the downward opening shape; the sheet structure is located in the slit-type gap, and the pressure plate is fixed to the bracket plate together with the pad by screws, and the photoelectric sensor is fixed under the base frame.

[0010] The side edges of the sheet structure are located between the inner sides of the pads, and the distance between the sides of the sheet structure is slightly smaller than the distance between the sides of the inner sides of the pads. The sheet structure can slide in the space formed by the pressing plate, the inner sides of the pads, and the bracket plate.

[0011] A square hole is provided in the middle of the base frame, the size of which is larger than the sensing head and is located on the upper and lower sliding tracks of the sensing head without colliding with the sensing head.

[0012] The photoelectric signal device of the photoelectric sensor is located below the square hole of the chassis, and the sensing head is just blocked in the middle of the photoelectric signal device when it falls.

[0013] The first guide wire component and the second guide wire component are also mounted on the base frame.

[0014] The first and second wire guide components are wire guide hooks. The height positions of the first and second wire guide components can adjust the tension of the raw silk. By adjusting the tension of the raw silk, the suspension sensor is stably pulled up and suspended by the raw silk passing through the wire guide porcelain eye.

[0015] The technical concept of the present invention is: when there is tension in the winding of raw silk, the suspended sensor can be pulled up. When the suspended sensor is pulled up, the sensing head of the sensing piece is located above the base frame and away from the photoelectric signal device. When the raw silk breaks during the winding process, the raw silk tension is 0. Under the action of gravity, the suspended sensor slides along the inner side of the pad in the space formed by the pressure plate, the pad and the support plate. The upper half of the sensing piece is stuck on the plane of the base frame, and the sensing head passes through the square hole of the base frame and blocks the photoelectric signal device of the photoelectric sensor, thereby blocking the light path of the photoelectric signal device of the photoelectric sensor. The photoelectric sensor sends a broken silk signal in real time.

[0016] The present invention has the advantages of being able to send a wire breakage signal without delay after a wire breakage occurs, having a simple structure, and being low-cost. Furthermore, the present invention can be directly embedded and installed before the winding frame of an existing raw silk fineness testing device without affecting the structure of the raw silk fineness testing device. Relying on its own structure, the raw silk is generated with sufficient tension to support suspended operation, making it a convenient upgrade for existing equipment.

[0025] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] The embodiment provides a suspended real-time broken wire detection device. Figure 1 As shown: the broken wire detection device 7 is fixed to the wire guide plate 9 by a screw 8, and a front wire guide hook 13 and a rear wire guide hook 10 are respectively provided on both sides of the broken wire detection device 7, and are also fixed on the wire guide plate 9 and can move with the wire guide plate 9. The wire guide plate 9 is arranged on the mounting base 5, and a wire guide roller 3 is provided near the left side of the front wire guide hook 13. The wire guide hook 4 is located between the front wire guide hook 13 and the wire guide roller 3. The inspection silk ingot 2 is placed on the balance 1, and the raw silk 11 to be inspected bypasses the wire guide roller 3 and passes through the wire guide hook 4, the front wire hook 13, the broken wire detection device 7, and the rear wire guide hook 10 and is wound on the winding rack 12. Sampling is completed according to the inspection requirements.

[0027] like Figure 2 、 Figure 3 The broken wire detection device 7 includes a base frame 71, a support plate 76 integrated with the base frame 71, a pressure plate 72, a suspension sensor 73, a pad 75, and a photoelectric sensor 78. A pad 75 is provided between the support plate 76 and the pressure plate 72. The structure of the pad 75 is as follows: Figure 6 As shown, it is in the form of a lower opening, and the suspension sensor 73 is located in the space formed by the opening of the pad 75. The pressure plate 72 is fixed to the bracket plate 76 together with the pad 75 by screw 2 74, and the photoelectric sensor 78 is fixed to the bottom of the base frame 71 by screw 3 77.

[0028] The suspension sensor 73 is composed of a sensing plate 731 and a wire guide eye 732. The wire guide eye 732 is made of wear-resistant alumina material for the raw silk 11 to pass through. The wire guide eye 732 is in direct contact with the raw silk 11 and generates sliding friction with the raw silk 11 during operation. The material of the wire guide eye 732 can reduce damage to the raw silk 11. The sensing plate 731 and the wire guide eye 732 are fixed together with glue; Figure 7 The end of the sensing piece 731 away from the wire guide porcelain eye 732 is the sensing head 735, the side edge 733 of the sensing piece is located between the inner side edge 751 of the pad, and the distance between the two sides of the side edge 733 of the sensing piece is slightly smaller than the distance between the two sides of the inner side edge 751 of the pad. The suspended sensor 73 can be supported by the detected raw silk 11 in the space formed by the pressure plate 72, the inner side edge 751 of the pad, and the support plate 76 and suspend and slide. When the raw silk 11 breaks, it loses support and falls.

[0029] A square hole 711 is defined in the center of the base frame 71. This hole is larger than the sensing head 735 and is located on the upward and downward sliding path of the sensing head 735, allowing the sensing head 735 to pass through the square hole 711. A photoelectric signal detector 781 of the photoelectric sensor 78 is located below the square hole 711. When the raw silk 11 breaks, the sensing head 735 loses support and falls, precisely blocking the center of the photoelectric signal detector 781.

[0030] During the fineness test of raw silk, the winding frame 12 rotates clockwise under the power, and the wound raw silk 11 is unwound from the spindle 2. According to the provisions of GB / T 1798-2008 "Test Method for Raw Silk", the sampling length each time is 100 windings (each winding length is 1 turn = 1.125m), and the balance 1 stops after the winding is completed. The difference in readings obtained before and after sampling is the weight of each 100 turns of silk. According to the formula: fineness (D) = 9000 * weight difference (g) / (100 * 1.125), the fineness value of the sample can be calculated; the raw silk 11 generates a certain tension during winding, and the height positions of the front wire guide hook 13 and the rear wire guide hook 10 can meet the tension of the raw silk 11, so that the suspension sensor 73 is pulled up by the raw silk 11 passing through the wire guide porcelain eye 732, and the top edge 734 of the induction plate of the suspension sensor 73 collides with the limit edge 752 of the pad and reaches the highest point. As long as the raw silk 11 can pull up the suspension sensor 73 when there is tension in the winding. When the suspension sensor 73 is pulled up, the sensing head 735 of the sensing piece 731 is located above the base frame 71 and away from the photoelectric signal detector 781; when the raw silk 11 is broken during winding, the tension of the raw silk 11 is 0, and the suspension sensor 73 slides along the inner side 751 of the pad under the action of gravity in the space formed by the pressure plate 72, the pad 75, and the bracket plate 76. The upper half of the sensing piece 731 is stuck on the plane of the base frame 71 and is limited and cannot fall anymore. The sensing head 735 passes through the square hole 711 of the base frame and blocks the photoelectric signal detector 781 of the photoelectric sensor 78, blocking the light path of the photoelectric signal detector 781 of the photoelectric sensor 78, and the photoelectric sensor 78 sends a broken silk signal in real time. Figure 4 、 Figure 5 It is the position state of the suspension sensor 73 when the wire breaks.

[0031] like Figure 8 A detection square hole 721 is opened in the middle of the pressure plate 72, and a detection square hole similar to the pressure plate 72 is also opened in the middle of the support plate 76. The wire guide porcelain eye 732 on the suspension sensor 73 can move up and down within the detection square hole without hindrance, which also ensures that the raw silk 11 passing through the wire guide porcelain eye 732 is not disturbed, thereby ensuring the smooth progress of the raw silk fineness test.

[0032] As mentioned above, when the raw silk 11 is broken during winding, the sensing head 735 of the suspension sensor 73 blocks the photoelectric signal device 781, and the photoelectric sensor 78 sends a broken silk signal in real time. The number of turns sensor and the rotation angle detector in the detection system record the position of the broken silk in real time, that is, the number of turns of the winding frame and the current rotation angle. From this, the length of the silk that has been wound can be calculated, providing accurate data for the subsequent measurement of the insufficient silk length, ensuring the uniformity of the sampling length (100 times) and the accuracy of the automatic detection of the raw silk fineness.
