Description
Technical Field
[0001] The utility model belongs to the technical field of textile processing, in particular to a broken wire detection device for a jacquard machine component. Background Art
[0002] The jacquard machine is a mechanical device widely used in the textile industry, and its main function is to control the pattern and texture of the fabric. During the weaving process, the jacquard machine can precisely control the rise and fall of the warp through its unique opening device assembly, thereby forming a series of complex openings on the working surface of the loom. During the operation of the jacquard machine, the heating wire is an indispensable key component of the jacquard machine. Its core function is to provide stable and controllable heat support for each link in the textile production process through an efficient power conversion mechanism. From the pretreatment of the fiber to the final shaping of the finished product, the heating wire runs through the entire production process, ensuring that the material is processed at the appropriate temperature to achieve the expected physical and chemical properties. However, if the heating wire is in a high-temperature working state for a long time, it may break due to factors such as material aging, current overload or mechanical stress. In order to ensure production safety and avoid production interruptions or product quality problems caused by equipment failure, the jacquard machine is usually equipped with a detection device to monitor the status of the heating wire in real time;
[0003] At present, the broken wire detection device of the traditional jacquard machine component is connected to the spring, and the spring is always in a stretched state. If the heating wire remains intact, it will maintain a certain tension and shape. Once the heating wire breaks, the tension and shape will change. Then the sensor probe will capture the change of the spring and issue an alarm to remind the operator to replace the heating wire. During the long detection process, the fine textile wool in the air may gradually adhere to the surface of the sensor probe, forming a layer of imperceptible dirt. This layer of dirt may not only block the sensitive elements of the probe and affect its accurate perception of changes in external physical quantities, but may also cause additional electrical signal interference due to differences in material properties, thereby greatly reducing the accuracy and reliability of sensor detection.

[0022] 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.
[0023] like Figures 1 to 6As shown, the utility model provides a broken wire detection device for a jacquard machine assembly, comprising a main body 1 and a mounting plate 27, a connecting plate 2 is fixedly mounted on the top of the mounting plate 27, a support block 3 is fixedly mounted on one end of the top of the connecting plate 2, a support block 4 is slidably connected to the other end of the top of the connecting plate 2, a heating wire 5 is provided on the side opposite to the top of the support block 3 and the top of the support block 4, a mounting block 6 is fixedly mounted on the side of the top of the connecting plate 2 close to the surface of the support block 4, a spring 7 is fixedly mounted on the side of the mounting block 6 close to the support block 4, the other end of the spring 7 is fixedly connected to one side of the support block 4, and a sensor 8 is provided inside the support block 4;
[0024] A cleaning mechanism is arranged on a side of support block 2 4 close to support block 1 3, and the cleaning mechanism includes a fixed shell 9, which is fixedly connected to a side of support block 2 4 close to support block 1 3, and a rotating rod 19 is fixedly installed on a side of the fixed shell 9 away from support block 2 4, and a cleaning brush 10 is provided on the surface of the rotating rod 19, and a gear 11 located inside the fixed shell 9 is fixedly installed on the other end of the fixed shell 9, a support groove 12 is opened on one side of the interior of the fixed shell 9, and a slider 13 is slidably connected to the interior of the support groove 12, and a rack 14 meshing with the gear 11 is fixedly installed on one side of the slider 13, and a connecting ring 15 is fixedly installed on the middle part of one side of the rack 14, and a motor 16 is fixedly installed on the interior of the fixed shell 9 close to the support block 2 4, and a push rod 17 is fixedly installed on the output end of the motor 16, and a connecting block 18 inside the connecting ring 15 is fixedly installed on one side of the push rod 17.
[0025] The above solution is adopted: the operator drives the device, and then the device will position and fix the textile to be processed, and then the device will send the textile to the top of the heating wire 5, and then the heating wire 5 can be driven, and then the heating wire 5 will heat the textile. When the heating wire 5 is working, the sensor 8 will always detect the state of the heating wire 5. Since the support block 2 4 is always fixedly connected to the spring 7, and the spring 7 is always in a stretched state, if the heating wire remains intact, it will maintain a certain tension and shape. Once the heating wire breaks, this tension and shape will change. This change can be captured by the probe on the surface of the sensor 8, and then the sensor 8 will trigger the alarm to sound an alarm, thereby reminding the operator to replace the heating wire 5;
[0026] When the sensor 8 is under long-term detection and the probe on the surface of the sensor 8 needs to be cleaned, the motor 16 can be driven to rotate the push rod 17, and then the push rod 17 will drive the connecting block 18 to slide inside the connecting ring 15, and then the push rod 17 will push the connecting ring 15 to move back and forth, and then the connecting ring 15 will drive the rack 14 to move back and forth. Since the rack 14 is engaged with the gear 11, when the rack 14 moves, it will drive the gear 11 to rotate back and forth, and the gear 11 will drive the rotating rod 19 to rotate, and the rotating rod 19 will drive the cleaning brush 10 to rotate back and forth. Since the bristles on one side of the cleaning brush 10 will contact the probe on the surface of the sensor 8, when the cleaning brush 10 rotates, the probe on the surface of the sensor 8 can be cleaned. Finally, the rotating rod 19 and the cleaning brush 10 are rotated back and forth by driving the motor 16, and then the probe can be cleaned, thereby avoiding the influence of fine textile wool on the detection accuracy and response speed of the probe, and improving the reliability and stability of the sensor detection.
[0027] like Figure 4 and Figure 6 As shown, a fixing ring 20 is fixedly installed on the surface of the rotating rod 19, and the surface of the fixing ring 20 contacts the surface of the fixed shell 9, and the surface of the gear 11 contacts one side of the inside of the fixed shell 9. A thread groove 21 is provided on one side of the surface of the rotating rod 19, and the surface of the rotating rod 19 is threadedly connected to a nut 22 located on the surface of the thread groove 21.
[0028] The above solution is adopted: through the design of the fixing ring 20, when the rotating rod 19 rotates, the rotating rod 19 will drive the fixing ring 20 to rotate. Since the surface of the fixing ring 20 contacts the surface of the fixed shell 9, the fixing ring 20 cooperates with the gear 11, and then the rotating rod 19 can be limited, thereby increasing the stability of the rotation of the rotating rod 19. Through the design of the thread groove 21 and the nut 22, since the inside of the nut 22 fits with the thread groove 21, the nut 22 can be rotated. When the nut 22 rotates, it will move on the surface of the thread groove 21, and then the surface of the nut 22 will contact the surface of the cleaning brush 10, and then the cleaning brush 10 can be fixed to the surface of the rotating rod 19.
[0029] like Figure 4 As shown, a slot 23 is provided at the top of the fixed shell 9, a sealing plate 24 is provided at the top of the fixed shell 9, an insert rod 25 located inside the slot 23 is fixedly installed at the bottom end of the sealing plate 24, and threaded plates 26 are fixedly installed at both ends of the surface of the fixed shell 9, and the threaded plates 26 are designed to be longitudinally symmetrical about the center of the fixed shell 9.
[0030] The above solution is adopted: through the design of the slot 23, the sealing plate 24 and the insertion rod 25, when it is necessary to maintain the components inside the fixed shell 9, the insertion rod 25 can be removed from the top of the fixed shell 9, and then the sealing plate 24 will be away from the inside of the slot 23, and then the fixed shell 9 can be opened, and then the operator can maintain the components inside the fixed shell 9. Through the design of the threaded plate 26, the fixed shell 9 can be placed on one side of the surface of the support block 24, and then the fixing bolt can be inserted into the inside of the threaded plate 26, and then the fixed shell 9 can be fixed to one side of the surface of the support block 24.
[0031] like Figure 3 and Figure 6 As shown, there is a gap between the cleaning brush 10 and the fixed shell 9, and the bristles on one side of the cleaning brush 10 are relatively soft. The support groove 12 and the slider 13 are both T-shaped, and the surface of the slider 13 fits the inner wall of the support groove 12.
[0032] The above solution is adopted: through the design of the cleaning brush 10, since there is a gap between the cleaning brush 10 and the fixed shell 9, the fixed shell 9 will not interfere with the movement of the cleaning brush 10, and the bristles on one side of the cleaning brush 10 are relatively soft, so when cleaning the probe on one side of the sensor 8, the probe itself will not be damaged. Through the design of the support groove 12 and the slider 13, since the support groove 12 and the slider 13 are both T-shaped, when the rack 14 moves, the slider 13 will move inside the support groove 12, and then the slider 13 can support and limit the rack 14.
[0033] The working principle and use process of this utility model:
[0034] First, the operator can put the textile into the device, then drive the device, then the device can position and fix the textile, then the device will transport the textile to the surface of the heating wire 5, then the heating wire 5 can be driven, and then the heating wire 5 will heat the textile. When the heating wire 5 is working, the sensor 8 will always detect the state of the heating wire 5. If the heating wire remains intact, it will maintain a certain tension and shape. Once the heating wire breaks, the tension and shape will change. This change can be captured by the probe on the surface of the sensor 8, and then the sensor 8 will trigger the alarm to sound an alarm, thereby reminding the operator to replace the heating wire 5;
[0035] When it is necessary to clean the probe on one side of the sensor 8, the motor 16 can be driven to rotate the push rod 17 and the connecting block 18, and then the connecting block 18 will move inside the connecting ring 15, and then the push rod 17 will push the connecting ring 15 and the rack 14 to move, and when the rack 14 moves, the slider 13 will move inside the support groove 12, and then the rack 14 can be limited, and then the rack 14 will drive the gear 11 and the rotating rod 19 to rotate back and forth, and the rotating rod 19 will drive the cleaning brush 10 to rotate, and when the cleaning brush 10 rotates, the bristles on one side of the cleaning brush 10 will contact the probe, and then the probe can be cleaned, thereby ensuring the stability of the detection of the heating wire 5, and finally completing the operation process.
