Description

Technical Field

[0001] This utility model belongs to the field of carpet production, specifically an automatic detection device for carpet weaving yarn frames. Background Technology

[0002] The carpet weaving frame includes support rods and multiple yarn bobbin rods. The support rods support the frame, and the yarn bobbin rods are evenly distributed and vertically fixed to the support rods. Spinning requires winding the yarn onto the bobbins. Due to excessive frictional resistance between the bobbins and the frame, the inner wall of the bobbin is severely worn, which can easily cause the yarn attached to the outer wall to tilt, resulting in the yarn at the release point deviating from the prescribed track and causing the textile yarn to become disordered. Therefore, the frame needs to be manually inspected regularly to ensure the proper functioning of the device.

[0003] In existing technologies, the tilt detection of yarn bobbins is generally carried out by staff manually checking each one, which is very labor-intensive, has low accuracy, and consumes a lot of time, thus reducing the efficiency and accuracy of yarn bobbin detection. In addition, existing yarn frames lack tension detection mechanisms. If the tension is too high or too low, it will lead to breakage or increase the breakage frequency, thereby reducing the production quality and efficiency of carpets. Utility Model Content

The first and second bevel gears are meshed together. The first sliding frame is connected to the outside of the second lead screw through a lead screw and nut pair.

[0008] In a preferred embodiment, the offset detection component includes limiting rods, which are symmetrically and equidistantly fixed to the inside of a slip ring. A plurality of sliders are slidably connected to the outside of the corresponding limiting rods. A spring is provided outside the limiting rods and between the sliders and the inner wall of the slip ring.

[0011] The beneficial effects of this utility model are as follows:

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-7 An automatic detection device for carpet weaving yarn racks includes a housing 1. Through holes 2 are equidistantly arranged inside the housing 1. A magnetic block is located at the rear of the housing 1. Slip rings 3 are slidably connected inside each of the through holes 2. Slider blocks 4 are equidistantly slidably connected inside each slip ring 3. A first sliding frame 5 is equidistantly slidably connected to the top of the housing 1. Fixed rods 6 are symmetrically fixedly connected inside the first sliding frame 5. A second sliding frame 7 is equidistantly slidably connected to the top of the housing 1 near the fixed rods 6. A detection roller 8 is installed on one side of the interior of the second sliding frame 7. A transmission assembly is located inside the housing 1, and an offset detection assembly is located inside each slip ring 3.

[0024] Specifically, the transmission assembly includes a first lead screw 9 and a linkage unit. The first lead screw 9 is equidistantly rotatably connected to the inside of the housing 1 near the through hole 2. A motor 10 is equidistantly fixed to the outside of the housing 1 via a mounting plate. The output end of the motor 10 extends into the inside of the housing 1 and is fixedly connected to the corresponding first lead screw 9. Multiple slip rings 3 are respectively connected to the outside of the corresponding first lead screw 9 via lead screw and nut pairs. The first sliding frame 5 can slide through the linkage unit. The linkage unit includes a first synchronous pulley 11, which is fixedly connected to the outside of the output end of the motor 10. A rotating shaft 12 is equidistantly rotatably connected to the upper part of the inside of the housing 1. A second synchronous pulley 13 is fixedly connected to one end of the rotating shaft 12. The first synchronous pulley 11 and the second synchronous pulley 13 are connected by a synchronous belt. 14. Transmission connection: A first bevel gear 15 is fixedly connected to the end of the rotating shaft 12 away from the second synchronous wheel 13. A second lead screw 16 is rotatably connected to the top of the housing 1 at equal distances. A second bevel gear 17 is fixedly connected to one end of the second lead screw 16. The first bevel gear 15 and the second bevel gear 17 are meshed together. The first sliding frame 5 is connected to the outside of the second lead screw 16 through a lead screw and nut pair. The offset detection component includes a limit rod 20. The limit rod 20 is symmetrically fixedly connected to the inside of the slip ring 3 at equal distances. Multiple sliders 4 are slidably connected to the outside of the corresponding limit rod 20. A spring 21 is provided outside the limit rod 20 and between the slider 4 and the inner wall of the slip ring 3. A contact sensor 22 is fixedly connected inside the slip ring 3 at equal distances between every two limit rods 20.

[0025] The above technical solution involves first attaching the device to the outside of the yarn bobbin, then fixing it to the yarn frame via magnetic attraction on the back, and passing the corresponding yarn through the through slot 19. When testing is required, the motor 10 is started via an external controller. The output of the motor 10 drives the first lead screw 9 and the first synchronous pulley 11 to rotate. The first lead screw 9, through the lead screw nut pair, drives the slip ring 3 to move inward. The slip ring 3 then drives the roller 23 inside the slider 4 to roll outside the yarn bobbin, thereby pushing the slider 4 inward under the limit of the limiting rod 20 through a reaction force, compressing the spring 21 and causing it to deform. This then drives the slip ring 3 to continue rolling outside the yarn bobbin towards the housing 1. During the inward movement, if the yarn bobbin shifts or tilts, the corresponding slider 4 experiences greater pressure, causing it to move further inward and contact the contact sensor 22. The contact sensor 22 then transmits the received signal to the external controller, which displays the direction of the yarn bobbin's shift on its screen, allowing staff to observe and confirm the test results. If the yarn bobbin does not shift or tilt, it indicates that the yarn bobbin is in a normal horizontal state. Furthermore, during the rotation of the first synchronous pulley 11, the synchronous belt 14 drives the second synchronous pulley 13 and the rotating shaft 12 to rotate, causing the rotating shaft 12 to drive the first bevel gear 15 to rotate. Then, through the meshing relationship, the second bevel gear 17 and the second lead screw 16 rotate. The second lead screw 16 drives the first sliding frame 5 and the fixed rod 6 to move towards one side of the detection roller 8 through the lead screw nut pair, thereby pushing the corresponding yarn closer to the detection roller 8. After the yarn is pushed, the electric telescopic rod 18 is activated. The output end of the electric telescopic rod 18 pushes the second sliding frame 7 and the detection roller 8 towards the yarn until they come into contact with the yarn, pushing the yarn towards the other side of the fixed rod 6. The tension of the yarn can then be detected by the tension sensor between the detection roller 8 and the second sliding frame 7 (this is known prior art and will not be elaborated). If the yarn tension is too high or too low, the connection will be... The received signal is transmitted to the display screen of the external controller for easy observation by staff. This effectively prevents yarn breakage or increased breakage frequency caused by excessively high or low yarn tension. If the tension is normal, no display is shown. This device can detect the offset of the yarn bobbin by using the slider 4 and roller 23 in conjunction with the sensor 22, avoiding the trouble of manual inspection and effectively reducing the burden of manual labor. Furthermore, the accurate detection by the sensor improves the detection efficiency and accuracy. It can also simultaneously detect the yarn tension to prevent breakage or increased breakage frequency caused by excessively high or low yarn tension, further enhancing the practicality and functionality of this device.

[0026] Specifically, electric telescopic rods 18 are fixedly connected at equal intervals to the top of the housing 1. The output ends of the multiple electric telescopic rods 18 are fixedly connected to the corresponding second sliding frame 7. A tension sensor is provided at the connection between the detection roller 8 and the second sliding frame 7. Through slots 19 are opened at equal intervals on the top of the housing 1 and are connected to the corresponding through holes 2. Rollers 23 are rotatably connected to the inner side of multiple sliders 4. The motor 10 is electrically connected to the external controller. Multiple contact sensors 22 and tension sensors are electrically connected to the external controller.

[0027] Through the above technical solution, the roller 23 allows the slider 4 to move better outside the yarn drum, thereby increasing the detection accuracy. The external controller allows the staff to quickly control the motor 10.

[0028] In use, first, the device is fitted onto the outside of the yarn bobbin. Then, the device is magnetically attached to the yarn frame via the magnetic block on the back. The corresponding yarn is then passed through the through slot 19. When testing is required, the motor 10 is started via an external controller. The output of the motor 10 drives the first lead screw 9 and the first synchronous pulley 11 to rotate. The first lead screw 9 drives the slip ring 3 to move inward through the lead screw nut pair. The slip ring 3 then drives the roller 23 inside the slider 4 to roll outside the yarn bobbin. This reaction force pushes the slider 4 inward under the limit of the limiting rod 20, compressing the spring 21 and causing it to deform. Then, the slip ring 3 continues to move from outside the yarn bobbin to inside the housing 1. If the yarn bobbin deviates during the movement... If the yarn bobbin tilts, the corresponding slider 4 will experience greater pressure, causing it to move further inward and contact the contact sensor 22. The contact sensor 22 then transmits the received signal to the external controller, which displays the direction of the yarn bobbin's offset on its screen. This allows staff to observe and confirm the test results. If the yarn bobbin does not tilt, it indicates that the yarn bobbin is in a normal horizontal state. During the rotation of the first synchronous pulley 11, the synchronous belt 14 drives the second synchronous pulley 13 and the rotating shaft 12 to rotate, causing the rotating shaft 12 to drive the first bevel gear 15 to rotate. The first bevel gear 15 then drives the second bevel gear 17 and the second lead screw 16 to rotate through a meshing relationship. The second lead screw 16... The lead screw and nut pair drive the first sliding frame 5 and the fixed rod 6 to move towards one side of the detection roller 8, thereby pushing the corresponding yarn closer to the detection roller 8. After the yarn is pushed, the electric telescopic rod 18 is activated. The output end of the electric telescopic rod 18 pushes the second sliding frame 7 and the detection roller 8 towards the yarn until they come into contact with the yarn, pushing the yarn towards the other side of the fixed rod 6. The tension of the yarn can then be detected by the tension sensor between the detection roller 8 and the second sliding frame 7 (this is known prior art and will not be elaborated). If the yarn tension is too high or too low, the received signal is transmitted to the display screen of the external controller for easy observation by the staff. This effectively avoids yarn breakage caused by excessively high or low yarn tension. If the breakage frequency increases, it will not be displayed if the tension is normal. This device can detect the offset of the yarn bobbin by using the slider 4 and roller 23 in conjunction with the sensor 22, avoiding the trouble of manual detection and effectively reducing the burden of manual labor. The accurate detection by the sensor improves the detection efficiency and accuracy. It can also detect the yarn tension simultaneously, avoiding breakage or increased breakage frequency caused by excessive or insufficient yarn tension, further improving the practicality and functionality of the device. The roller 23 allows the slider 4 to move better outside the yarn bobbin, thereby increasing the detection accuracy. The motor 10 can be quickly controlled by the operator through the external controller.
