Description

Technical Field

[0001] This invention relates to the field of warp tension detection technology, and more particularly to a warp tension detection device for ribbon production. Background Technology

[0002] Ribbons are made from various yarns into narrow or tubular fabrics. There are many varieties of ribbon fabrics, which are widely used in various industries such as clothing, footwear, bags, industry, agriculture, military supplies, and transportation. In the production process of ribbons, warp machines are used. Tension detection devices are used to detect the tension of the warp machines, that is, to detect and adjust the tension to ensure constant tension, thereby ensuring the weaving effect.

[0003] However, the existing technology still has the following defects or problems: First, the current tension detection device relies solely on mechanical force to adjust the tension, which is not ideal in terms of the accuracy of tension adjustment and does not have a buffering effect, which can easily cause yarn breakage. Second, since the warp rollers of current warp machines are multiple rollers working simultaneously, multiple tension detection devices are required. However, the current tension detection devices are generally fixedly installed on the warp machine. When changing to different models of rollers, it is difficult to change the tension detection devices and adjust the positions of the tension detection devices on the warp machine according to the corresponding model of roller, and it is not convenient to adjust the spacing between the tension detection devices. Summary of the Invention

[0008] Preferably, a fixing bolt is fitted onto the top of the mounting plate one, and a mounting plate two is fixedly connected to one side of the side plate. The outer wall of the mounting plate two has a plurality of equidistant mounting holes.

[0009] Preferably, the adjusting head includes a movable block, which is threadedly connected to a lead screw. An annular groove is formed on the outer wall of the middle part of the movable block. A connecting ring is sleeved on the movable block at the annular groove. A first magnetic block is rotatably connected inside the connecting ring. A rotating shaft is fixedly connected to the other end of the first magnetic block. Placement slots are formed on both sides of the interior of the movable block. A locking block is placed inside the placement slot. A second magnetic block is sleeved inside the locking block. A locking groove matching the locking block is formed on both sides of the connecting ring.

[0010] Preferably, the first magnetic block corresponds to the card slot, the first magnetic block and the card slot are located on the same plane, and the moving block, connecting ring, card block and rotating shaft are all made of hard material and none of them have magnetic properties.

[0011] Preferably, a controller is fixedly installed on the outer wall of the side plate, and the controller is electrically connected to the stepper motor.

[0012] Preferably, the adjustment mechanism includes a connecting frame, which is fixedly connected to the outer wall of the slider. A base plate is fixedly connected to the bottom of the connecting frame, and a push rod motor is fixedly installed on the outer wall of the base plate. The push rod motor is electrically connected to the controller.

[0013] Preferably, the detection mechanism includes a connecting plate, the output end of the push rod motor is fixedly connected to the outer wall of the connecting plate, a movable rod is slidably sleeved on the outer wall of the connecting plate, a detection plate is fixedly connected to the top of the movable rod, a spring is sleeved on the bottom of the detection plate, a pressure plate is provided on the top of the spring, the pressure plate and the movable rod are sleeved together, a pressure sensor is fixedly installed on the lower surface of the connecting plate, the pressure sensor and the pressure plate correspond to each other, the pressure plate is located between the pressure sensor and the spring, a guide wheel is fixedly connected to the bottom end of the movable rod, and the spring is located between the pressure plate and the guide wheel.

[0014] Preferably, an infrared rangefinder is fixedly installed on the outer wall of the base plate. The infrared rangefinder is electrically connected to the controller, and the lower surface of the infrared rangefinder corresponds to the upper surface of the detection plate.

[0015] Preferably, a rod is fixedly connected to the upper surface of the guide wheel, a threaded hole is provided on the outer wall of the rod, a sleeve matching the rod is fixedly connected to the lower surface of the movable rod, and a fixing screw matching the threaded hole is threadedly connected to the outer wall of the sleeve.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. In this invention, through the design of stepper motor, output shaft, lead screw and adjustment head, after replacing different models of guide wheels, the spacing between each detection mechanism can be adjusted according to the size of the newly replaced guide wheel, which is different from the traditional method and does not require disassembly and reinstallation of the detection mechanism.

[0018] 2. In this invention, the adjustment mechanism works in conjunction with the detection mechanism. The push rod motor pushes the connecting plate to move downward. The connecting plate drives the guide wheel to move downward through the movable rod. The guide wheel applies pressure to the yarn, thereby providing a certain tension to the yarn. At this time, the spring is compressed. The spring compresses the pressure sensor through the pressure plate. The pressure sensor detects the tension in real time and transmits the signal to the controller. The controller can display the tension value on the yarn in real time.

[0019] 3. In this invention, during the warping process, the fluctuation of the yarn causes tension changes. When the tension on the yarn decreases, the spring drives the guide wheel to move downwards. At this time, the tension value detected by the pressure sensor also decreases. The push rod motor drives the connecting plate to move downwards, and the connecting plate drives the guide wheel downwards, thereby increasing the tension. When the tension on the yarn increases, the yarn further compresses the guide wheel, which in turn compresses the spring and moves upwards. At this time, the tension value detected by the pressure sensor also increases. The push rod motor drives the connecting plate to move upwards, and the connecting plate drives the guide wheel upwards, thereby reducing the tension. This allows for real-time tension adjustment and ensures constant tension. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] As attached Figure 1 To be continued Figure 6As shown, a tension detection device for a warp yarn machine used in ribbon production includes a mounting plate 1. Side plates 2 are welded to both sides of the mounting plate 1. A stepper motor 3 is fixedly mounted on the outer wall of the side plate 2. An output shaft 4 is fixedly connected to the output end of the stepper motor 3. A lead screw 5 is rotatably connected to the outer wall of the side plate 2. The output shaft 4 is connected to the lead screw 5 via a bevel gear. An adjusting head 6 is threadedly connected to the outer wall of the lead screw 5. A connecting column 12 is fixedly connected to the outer wall of the adjusting head 6. A slide rod 9 is fixedly connected to the outer wall of the slide rod 9. A slider 10 is slidably connected to the outer wall of the slide rod 9. An adjusting mechanism 7 is fixedly connected to the outer wall of the slider 10. A detection mechanism 8 is fixedly connected to the output end of the adjusting mechanism 7. There are multiple adjusting heads 6, adjusting mechanisms 7, detection mechanisms 8, sliders 10, and connecting columns 12. The multiple adjusting heads 6 are arranged horizontally along the direction of the lead screw 5.

[0037] As attached Figure 1 As shown, a fixing screw 11 is threadedly connected to the outer wall of the slider 10, and the other end of the fixing screw 11 is in contact with the outer wall of the slider 9.

[0038] In the above technical solution, the fixing screw 11 is used to fix the slider 10, prevent the slider 10 from sliding along the sliding rod 9, and improve the stability of the device.

[0039] As attached Figure 1 As shown, a fixing bolt 13 is fitted onto the top of the mounting plate 1, and a mounting plate 2 14 is fixedly connected to one side of the side plate 2. The outer wall of the mounting plate 2 14 has multiple mounting holes 15 arranged at equal intervals.

[0040] In the above technical solution, the entire tension detection device is fixedly installed on the warp machine by the fixing bolts 13 on the mounting plate 1, or the tension detection device can be fixedly installed on the external mounting frame by screws through the mounting holes 15 on the mounting plate 2 14.

[0041] As attached Figure 1 To be continued Figure 6 As shown, the adjusting head 6 includes a moving block 601, which is threadedly connected to the lead screw 5. An annular groove 602 is formed on the outer wall of the middle part of the moving block 601. A connecting ring 603 is sleeved on the moving block 601 at the annular groove 602. A magnetic block 606 is rotatably connected inside the connecting ring 603. A rotating shaft 609 is fixedly connected to the other end of the magnetic block 606. Placement slots 604 are formed on both sides of the interior of the moving block 601. A locking block 605 is placed inside the placement slot 604. A magnetic block 608 is sleeved inside the locking block 605. A slot 607 matching the locking block 605 is formed on both sides of the connecting ring 603. The magnetic block 606 and the slot 607 correspond to each other and are located on the same plane. The moving block 601, the connecting ring 603, the locking block 605, and the rotating shaft 609 are all made of hard materials and none of them are magnetic.

[0042] In the above technical solution, when the adjustment head 6 needs to be moved, the rotating shaft 609 is manually rotated. The rotating shaft 609 drives the magnetic block 1 606 to rotate 180 degrees. At this time, the corresponding surfaces of the magnetic block 1 606 and the magnetic blocks 2 608 on both sides are opposite in orientation, and the magnetic block 1 606 and the magnetic blocks 2 608 on both sides attract each other. At this time, the magnetic blocks 2 608 drive the locking block 605 to insert into the locking slot 607. At this time, the locking slot 607 and the connecting ring 603 are connected into a whole by the locking block 605. When the lead screw 5 rotates, it can drive the adjustment position. The movable block 601 in the designated position moves horizontally. Since the movable blocks 601 in other positions are not connected to the connecting ring 603, the movable blocks 601 in other positions rotate together with the lead screw 5. That is, the movable block 601 drives the connecting column 12 to move horizontally through the connecting ring 603. The connecting column 12 drives the adjusting mechanism 7 and the detection mechanism 8 to move horizontally through the slider 10, thereby adjusting the position of the detection mechanism 8. That is, the spacing between each detection mechanism 8 can be adjusted according to the size of the newly replaced guide wheel 807.

[0043] When the detection mechanism 8 moves to the appropriate position, the slider 10 is fixed by the fixing screw 11. The magnetic block 606 is manually rotated to reset, so that the magnetic poles of the corresponding surfaces of the magnetic block 606 and the magnetic block 608 are the same. The magnetic block 606 repels the magnetic block 608. The magnetic block 608 drives the locking block 605 to move into the placement slot 604. When the lead screw 5 rotates, the moving block 601 will rotate with the lead screw 5, and the adjusting head 6 will not move horizontally.

[0044] As attached Figure 7 As shown, a controller 16 is fixedly installed on the outer wall of the side plate 2. The controller 16 is electrically connected to the stepper motor 3. The adjustment mechanism 7 includes a connecting frame 701, which is fixedly connected to the outer wall of the slider 10. A base plate 702 is fixedly connected to the bottom of the connecting frame 701. A push rod motor 703 is fixedly installed on the outer wall of the base plate 702. The push rod motor 703 is electrically connected to the controller 16.

[0045] In the above technical solution, the controller 16 controls the push rod motor 703 to work, and the push rod motor 703 pushes the detection mechanism 8 to move downward.

[0046] As attached Figure 7 To be continued Figure 8As shown, the detection mechanism 8 includes a connecting plate 801. The output end of the push rod motor 703 is fixedly connected to the outer wall of the connecting plate 801. A movable rod 802 is slidably sleeved on the outer wall of the connecting plate 801. A detection plate 803 is fixedly connected to the top of the movable rod 802. A spring 806 is sleeved on the bottom of the detection plate 803. A pressure plate 805 is provided on the top of the spring 806. The pressure plate 805 and the movable rod 802 are sleeved together. A pressure sensor 804 is fixedly installed on the lower surface of the connecting plate 801. The pressure sensor 804 and the pressure plate 805 correspond to each other. The pressure plate 805 is located between the pressure sensor 804 and the spring 806. A guide wheel 807 is fixedly connected to the bottom end of the movable rod 802. The spring 806 is located between the pressure plate 805 and the guide wheel 807.

[0047] In the above technical solution, the push rod motor 703 pushes the connecting plate 801 to move downward. The connecting plate 801 drives the guide wheel 807 to move downward through the movable rod 802. The guide wheel 807 applies pressure to the yarn, thereby providing a certain tension to the yarn. At this time, the spring 806 is compressed. The spring 806 compresses the pressure sensor 804 through the pressure plate 805. The pressure sensor 804 detects the tension in real time and transmits the signal to the controller 16. The controller 16 can display the tension value on the yarn in real time.

[0048] Meanwhile, during the warping process, the fluctuation of the yarn will cause changes in tension. When the tension on the yarn decreases, the spring 806 will drive the guide wheel 807 to move downward. At this time, the tension value detected by the pressure sensor 804 also decreases. At this time, the push rod motor 703 drives the connecting plate 801 to move downward, and the connecting plate 801 drives the guide wheel 807 downward, thereby increasing the tension.

[0049] When the tension on the yarn increases, the yarn further compresses the guide wheel 807, which in turn compresses the spring 806 and moves upward. At this time, the tension value detected by the pressure sensor 804 also increases. The push rod motor 703 then drives the connecting plate 801 to move upward, which in turn drives the guide wheel 807 upward, thereby reducing the tension. Meanwhile, during the tension adjustment process, the elasticity of the spring 806 acts as a buffer to prevent yarn breakage during tension adjustment.

[0050] As attached Figure 7 To be continued Figure 8 As shown, an infrared rangefinder 704 is fixedly installed on the outer wall of the base plate 702. The infrared rangefinder 704 is electrically connected to the controller 16, and the lower surface of the infrared rangefinder 704 corresponds to the upper surface of the detection plate 803.

[0051] In the above technical solution, when the connecting plate 801 moves up and down, the connecting plate 801 can drive the detection plate 803 to move up and down through the movable rod 802, and the infrared rangefinder 704 can detect the distance between itself and the detection plate 803 in real time. Therefore, the infrared rangefinder 704 can provide real-time feedback on the output stroke distance of the push rod motor 703, thereby ensuring that the push rod motor 703 can work normally within the working threshold.

[0052] As attached Figure 9 To be continued Figure 10 As shown, a rod 808 is fixedly connected to the upper surface of the guide wheel 807. A threaded hole 809 is opened on the outer wall of the rod 808. A sleeve 810 matching the rod 808 is fixedly connected to the lower surface of the movable rod 802. A fixing screw 811 matching the threaded hole 809 is threadedly connected to the outer wall of the sleeve 810.

[0053] In the above technical solution, when it is necessary to replace the guide wheel 807, loosen the fixing screw 811 and pull the plug rod 808 out of the sleeve 810. During installation, insert the plug rod 808 into the sleeve 810, and fix the guide wheel 807 by using the fixing screw 811 in conjunction with the threaded hole 809 on the plug rod 808.

[0054] The specific usage and function of this embodiment are as follows:

[0055] When using this invention, the entire tension detection device is fixedly installed on the warp machine by the fixing bolts 13 on the mounting plate 1;

[0056] The controller 16 controls the push rod motor 703 to work, which pushes the connecting plate 801 to move downward. The connecting plate 801 drives the guide wheel 807 to move downward through the movable rod 802. The guide wheel 807 applies pressure to the yarn, thereby providing a certain tension to the yarn. At this time, the spring 806 is compressed. The spring 806 compresses the pressure sensor 804 through the pressure plate 805. The pressure sensor 804 detects the tension in real time and transmits the signal to the controller 16. The controller 16 can display the tension value of the yarn in real time.

[0057] Meanwhile, during the warping process, the fluctuation of the yarn will cause changes in tension. When the tension on the yarn decreases, the spring 806 will drive the guide wheel 807 to move downward. At this time, the tension value detected by the pressure sensor 804 also decreases. At this time, the push rod motor 703 drives the connecting plate 801 to move downward, and the connecting plate 801 drives the guide wheel 807 downward, thereby increasing the tension.

[0058] When the tension on the yarn increases, the yarn will further squeeze the guide wheel 807, the guide wheel 807 squeezes the spring 806, and the guide wheel 807 moves upward. At this time, the tension value detected by the pressure sensor 804 also increases. At this time, the push rod motor 703 drives the connecting plate 801 to move upward, and the connecting plate 801 drives the guide wheel 807 upward, thereby reducing the tension.

[0059] Meanwhile, when the connecting plate 801 moves up and down, the connecting plate 801 can drive the detection plate 803 to move up and down through the movable rod 802, and the infrared rangefinder 704 can detect the distance between itself and the detection plate 803 in real time. Therefore, the infrared rangefinder 704 can provide real-time feedback on the output stroke distance of the push rod motor 703, thereby ensuring that the push rod motor 703 can work normally within the working threshold.

[0060] Please refer to the above structure and process. Figure 1 and Figure 6-8 .

[0061] When it is necessary to replace the guide wheel 807 with a different model, loosen the fixing screw 811 and pull the insert rod 808 out of the sleeve 810. During installation, insert the insert rod 808 into the sleeve 810 and fix the guide wheel 807 by using the fixing screw 811 in conjunction with the threaded hole 809 on the insert rod 808.

[0062] Please refer to the above structure and process. Figure 9-10 .

[0063] After replacing the guide wheel 807 with a different model, the spacing between each detection mechanism 8 can be adjusted according to the size of the newly replaced guide wheel 807. First, loosen the fixing screw 11 fixed at the slider 10, and manually rotate the shaft 609. The shaft 609 drives the magnetic block 606 to rotate 180 degrees. At this time, the corresponding surfaces of the magnetic block 606 and the magnetic blocks 608 on both sides are opposite, and the magnetic block 606 and the magnetic blocks 608 on both sides attract each other. At this time, the magnetic block 608 drives the locking block 605 to insert into the slot 607. At this time, the slot 607 and the connecting ring 603 are connected into a whole by the locking block 605.

[0064] The stepper motor 3 is started by the controller 16, and the stepper motor 3 drives the output shaft 4 to rotate. The output shaft 4 drives the lead screw 5 to rotate through the bevel gear.

[0065] At this time, the lead screw 5 drives the moving block 601 that needs to be adjusted to move horizontally. Since the moving blocks 601 in other positions are not connected to the connecting ring 603, the moving blocks 601 in other positions rotate together with the lead screw 5. That is, the moving block 601 drives the connecting column 12 to move horizontally through the connecting ring 603. The connecting column 12 drives the adjusting mechanism 7 and the detection mechanism 8 to move horizontally through the slider 10, thereby adjusting the position of the detection mechanism 8. That is, the spacing between each detection mechanism 8 can be adjusted according to the size of the newly replaced guide wheel 807.

[0066] When the detection mechanism 8 moves to the appropriate position, the slider 10 is fixed by the fixing screw 11. The magnetic block 606 is manually rotated to reset, so that the magnetic poles of the corresponding surfaces of the magnetic block 606 and the magnetic block 608 are the same. The magnetic block 606 repels the magnetic block 608. The magnetic block 608 drives the locking block 605 to move into the placement slot 604. When the lead screw 5 rotates, the moving block 601 will rotate with the lead screw 5, and the adjusting head 6 will not move horizontally.

[0067] Please refer to the above structure and process. Figure 1-6 .

[0068] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
