Description

Technical Field

[0001] The utility model relates to the technical field of yarn winding and unwinding, and more specifically, to a knitting yarn winding and unwinding device. Background Art

[0002] Yarn weaving is the process of weaving various yarn fibers into products of a certain fineness, such as weaving, rope making, thread making, knitting and embroidery. During the weaving process, the yarn will be placed and stored by winding it on the outside of the yarn tube, and then multiple groups of yarn tubes will be embedded in the wiring device, which not only stores the yarn but also facilitates the subsequent rotation of the yarn tube to unwind the yarn.

[0003] During the weaving process, the yarn is wound on a reel, and the unwinding of the yarn is achieved by connecting the rotating shaft of the servo motor with the rotating shaft of the reel. However, when the unwinding of the yarn on the reel stops, the reel will continue to rotate for a certain distance due to inertia driven by the servo motor, causing the yarn to loosen on the reel, resulting in uneven tension distribution of the yarn during the entire weaving process. When the unwinding is started again, the yarn is easily entangled. At the same time, the amount of yarn wound on the reel is also measured by observing and measuring the outer diameter of the take-up roller, and the yarn length measurement is inaccurate.

[0021] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To Attachment Figure 2 The embodiment of the utility model provides a knitting yarn winding and unwinding device, including a base 1, a support plate 21 is fixedly connected to the top of the base 1, a winding device 2 is fixedly connected to the top of the base 1 at one end of the support plate 21, a guide assembly 3 is fixedly connected to one side of the support plate 21 close to the winding device 2, a first guide wheel 4 is arranged below the guide assembly 3 in the middle of the support plate 21, a second guide wheel 5 is rotatably installed on the upper end of the other side of the support plate 21, a tension detection assembly 6 and an unwinding device 7 are arranged on the other side of the winding device 2, and the tension detection assembly 6 is located above the unwinding device 7; a central controller and an operation panel are arranged inside the support plate 21, and the central controller is: ST M32 single chip microcomputer; the winding device 2 includes a winding motor 22 fixedly installed on the side of the support plate 21, one side of the winding motor 22 is fixedly connected to a rotating disk 23, the rotating disk 23 is rotatably installed on the side of the support plate 21, the side of the rotating disk 23 is fixedly connected to a winding roller 24, the side of the support plate 21 is installed with a meter meter 25, the meter meter 25 is a Lanyin instrument Z96-F, and the outer surface of the meter meter 25 is in contact with the outer surface of the rotating disk 23, the upper end of one side of the support plate 21 is fixedly connected to an electric telescopic rod 26, one side of the electric telescopic rod 26 is provided with a support wheel 27, the outer surfaces of the winding roller 24 and the support wheel 27 are wound and connected with a yarn body 28, and the meter meter 25 is electrically connected to the central controller.

[0023] The rotation of the rotating disk 23 is used to control the rotation of the meter counter 25, and the length of the wound yarn is calculated by the number of revolutions of the meter counter 25. The corresponding length of the yarn to be wound is set on the control panel. When the meter counter 25 calculates that the yarn wound on the surface of the winding roller 24 reaches the calculated length, the signal is transmitted to the central controller, and the central controller stops the winding motor 22 for winding, thereby realizing fixed-length winding.

[0024] As attached Figure 3 As shown, the guide assembly 3 includes a support rod 31, which is fixedly installed on one side of the support plate 21, and one end of the support rod 31 is fixedly connected to a positioning ring 32, and the side of the positioning ring 32 close to the support wheel 27 is fixedly connected to a guide spring 33, and the guide spring 33 is movably sleeved on the outer surface of the yarn body 28. In the existing equipment, in order to make the yarn reel evenly, the electric telescopic rod 26 is started to control the support wheel 27 to reciprocate on one side of the winding roller 24, so that the yarn body 28 is evenly reeled on the left and right when it is reeled on the surface of the winding roller 24. When the yarn body 28 is pushed by the support wheel 27, when the distance of the yarn body 28 is far or the tension of the yarn body 28 is loose, it will cause the yarn body 28 to separate from the first guide wheel 4. The positioning ring 32 is used to position the end of the yarn close to the first guide wheel 4 to prevent the yarn body 28 from separating from the outer surface of the first guide wheel 4. At the same time, the guide spring 33 is used to guide the yarn body 28 active on the surface of the support wheel 27.

[0025] As attached Figure 4 As shown, the tension detection component 6 includes a fixed frame 61, one end of the fixed frame 61 is movably sleeved with a movable rod 62, one end of the movable rod 62 is provided with an extrusion wheel 63, the other end of the movable rod 62 is fixedly connected with a push block 64, one side of the push block 64 is fixedly connected with an extrusion spring 65, one side of the extrusion spring 65 is fixedly connected with a movable plate 66, and the push block 64 and the movable plate 66 are slidably installed inside the fixed frame 61.

[0026] Among them, the other end of the fixed frame 61 is fixedly connected to the positioning frame 611, and the side of the fixed frame 61 away from the extrusion wheel 63 is fixedly connected to the adjusting motor 610. The side of the adjusting motor 610 is provided with a rotating screw 69 rotatably installed inside the positioning frame 611. The outer surface of the rotating screw 69 is threadedly connected to the movable frame 68. The movable frame 68 is slidably installed on the outer surface of the positioning frame 611. One side of the movable frame 68 is fixedly connected to a pressure sensor 67, and the pressure sensor 67 is Siemens 7MF1567. The pressure sensor 67 is slidably installed inside the fixed frame 61. The pressure sensor 67 and the adjusting motor 610 are electrically connected to the central controller respectively.

[0027] The pressure sensor 67 is used to detect the tension on the squeezing wheel 63, and the position of the pressure sensor 67 inside the fixed frame 61 is adjusted by the central controller to detect the tension of the entire yarn.

[0028] As attached Figure 5 As shown, the unwinding device 7 includes an unwinding roller 71 rotatably mounted on the side of the support plate 21, the yarn body 28 is wound and connected to the outer surface of the unwinding roller 71, a connecting frame 72 is fixedly connected to one side of the support plate 21, an extrusion frame 73 is movably sleeved inside the connecting frame 72, a sleeve plate 75 is fixedly connected to the bottom of the extrusion frame 73, a pressing wheel 76 is rotatably mounted on the bottom of the sleeve plate 75, and the pressing wheel 76 is rollingly mounted on the surface of the yarn body 28 on the outer surface of the unwinding roller 71, and both sides of the extrusion frame 73 are located at the connecting A pressing spring 74 is arranged between the frames 72. The yarn on the surface of the unwinding roller 71 squeezes the pressing wheel 76, so that the socket plate 75 pushes the squeezing frame 73 and moves upward, and utilizes the reaction of the pressing spring 74 to make the yarn body 28 fit against the outer surface of the unwinding roller 71. On the one hand, it prevents the yarn from being scattered, and on the other hand, it increases the friction of the rotation of the unwinding roller 71 to avoid the sudden stop of the winding motor 22 during the winding process, causing the unwinding roller 71 to be affected by inertia and naturally unwind, thereby causing excessive unwinding of the yarn.

[0029] The working process of the utility model is as follows:

[0030] When in use, the yarn body 28 on the unwinding roller 71 passes through the side of the squeezing wheel 63, from the outer surface of the second guide wheel 5, through the bottom of the first guide wheel 4 and the inside of the guide spring 33, and is wound from the top of the support wheel 27 to the outer surface of the winding roller 24. At this time, the winding motor 22 controls the rotating disk 23 and the winding roller 24 to rotate, so that the winding roller 24 winds up the yarn body 28;

[0031] At this time, the meter counter 25 rotates, and the length of the wound yarn is calculated by the number of turns of the meter counter 25. The corresponding length of the yarn to be wound is set on the control panel. When the meter counter 25 calculates that the yarn wound on the surface of the winding roller 24 reaches the calculated length, the signal is transmitted to the central controller, and the central controller stops the winding motor 22 from winding, so that the winding roller 24 can be wound at a fixed length.

[0032] In the existing equipment, in order to make the yarn winding even, the electric telescopic rod 26 is started to control the support wheel 27 to reciprocate on one side of the winding roller 24, so that the yarn body 28 is wound on the surface of the winding roller 24, and the yarn body 28 is wound evenly on the left and right. When the yarn body 28 is pushed by the support wheel 27, when the yarn body 28 is far away or the tension of the yarn body 28 is loose, it will cause the yarn body 28 to separate from the first guide wheel 4. The positioning ring 32 is used to position the end of the yarn close to the first guide wheel 4 to prevent the yarn body 28 from separating from the outer surface of the first guide wheel 4. At the same time, the guide spring 33 is used to guide the yarn body 28 moving on the surface of the support wheel 27.

[0033] When the tension of the yarn body 28 is high, the pressure generated by the pressure sensor 67 will increase. When the pressure sensor 67 reaches the set threshold, the signal will be transmitted to the central controller, and the central controller will control the adjustment motor 610 to start the rotation of the screw 69. At this time, the movable frame 68 moves inside the positioning frame 611 and pushes the pressure sensor 67 to move left and right, adjust the deformation force of the extrusion spring 65, and then adjust the threshold value of the pressure sensor 67. When the threshold value of the pressure sensor 67 is large, it can be judged that the tension of the yarn body 28 is large.

[0034] The yarn on the surface of the unwinding roller 71 squeezes the pressing wheel 76, causing the socket plate 75 to push the squeezing frame 73 and move upward, and utilizing the reaction of the pressing spring 74 to make the yarn body 28 fit against the outer surface of the unwinding roller 71. On the one hand, this prevents the yarn from being scattered, and on the other hand, it increases the friction of the rotation of the unwinding roller 71 to avoid the sudden stop of the winding motor 22 during the winding process, causing the unwinding roller 71 to be affected by inertia and unwind naturally, thereby causing excessive unwinding of the yarn.
