Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology and relates to an intelligent yarn rack device. Background Technology

[0002] Yarn breakage has a significant impact on weaving efficiency and fabric quality, making rapid and accurate detection and timely control of yarn tension crucial. Currently, flat knitting machines on the market can only monitor the tension and breakage of a single strand of yarn, making it difficult to simultaneously control the tension of multiple strands and providing real-time monitoring of breakage across multiple strands, thus limiting their practicality.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a yarn tension control structure [application number: 201410216812.X], which includes a pair of guide rollers for transmitting yarn. Each pair of guide rollers has a rotating support on both sides. The rotating support rotates around the transmission trajectory of the yarn in the guide roller pair as its axis. The rotating support fixes a yarn guide ring through a radially arranged rocker arm. As the yarn passes through the yarn guide ring, the yarn guide rings of the rotating support between every two adjacent pairs of guide rollers rotate synchronously. However, this solution still has the drawback of difficulty in achieving simultaneous control of the tension of multiple yarns and real-time monitoring of multiple yarns for breakage during use, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an intelligent yarn rack device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart yarn frame device includes a yarn frame body, on which a plurality of yarn bobbins on which yarn is wound are mounted, and a plurality of parallel unwinding plates are provided on the yarn frame body. The parallel unwinding plates have a plurality of yarn guide holes facing the yarn bobbins. Below the parallel unwinding plates are a tension component base plate and a yarn probe fixing seat fixedly connected to the yarn frame body. The tension component base plate is provided with a multi-head yarn guide tension control component for controlling the tension of multiple strands of yarn, and the yarn probe fixing seat is provided with a multi-head yarn guide breakage detection structure, the multi-head yarn guide breakage detection structure corresponding to the position of the multi-head yarn guide tension control component.

[0007] In the aforementioned intelligent yarn frame device, the multi-head guide tension control component includes a tension adjustment plate disposed on the tension component base plate, which can reciprocate linearly in the horizontal direction. The tension adjustment plate is provided with a plurality of first gate fixing seats, and floating gates are screwed onto the first gate fixing seats. The tension component base plate is provided with a plurality of second gate fixing seats, and fixed gates are screwed onto the second gate fixing seats. The floating gates can reciprocate linearly along one end close to or away from the fixed gates.

[0008] In the aforementioned intelligent yarn rack device, the floating gate and the fixed gate are arranged facing each other and staggered. When the floating gate and the fixed gate are closed, the gate plates of the floating gate and the gate plates of the fixed gate abut against each other in an alternating manner.

[0009] In the aforementioned intelligent yarn frame device, the tension assembly base plate is provided with a motor base and a servo motor. A lead screw is connected to the rotating shaft of the servo motor. A floating connecting seat is installed on the tension adjustment plate. The lead screw passes through the floating connecting seat, and the floating connecting seat and the lead screw are screwed together by a lead screw nut.

[0010] In the aforementioned intelligent yarn rack device, the motor base is provided with a positioning pin, which is positioned opposite to the clearance notch of the lead screw nut, and the tension assembly base plate is provided with a pretension spring connected to the floating connecting seat.

[0011] In the aforementioned intelligent yarn frame device, the tension component base plate is also provided with several upper guide ceramic seats, the upper guide ceramic seats are provided with upper guide ceramic rings, and the upper guide ceramic rings are provided with upper guide holes.

[0012] In the above-mentioned intelligent yarn frame device, the multi-head guide yarn breakage detection structure includes a plurality of yarn probes set on the yarn probe fixing seat, and a lower guide yarn pressure roller installed on the yarn probe fixing seat is provided between the yarn probe and the yarn guide hole.

[0013] In the above-mentioned intelligent yarn frame device, the lower guide roller includes several guide ceramic rod seats and guide rollers disposed on the guide fixed seat, and guide ceramic rods are mounted on the guide ceramic rod seats.

[0014] In the aforementioned intelligent yarn rack device, the guide ceramic rod has guide claws.

[0015] In the above-mentioned intelligent yarn frame device, the main body of the yarn frame is provided with several insert rods for fixing the yarn bobbin, and the center line of the insert rod coincides with the center line of the yarn guide hole.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In use, this utility model places several yarn bobbins with wound yarn on the yarn frame body. The yarn passes through the yarn guide holes of the parallel unwinding plates and then through the multi-head yarn tension control component. First, the yarn is guided by the multi-head yarn tension control component, and then the tension of the yarn is controlled by the tension gate structure, realizing simultaneous control of the tension of multiple yarns. Then, the yarn is guided by the multi-head yarn breakage detection structure, and then the yarn probe structure monitors the multiple yarns in real time for whether they are broken. This device can simultaneously control the tension of multiple yarns and simultaneously monitor whether multiple yarns are broken. It solves the problem that the tension and breakage of a single yarn can only be controlled by a single gate and a single probe, greatly improving efficiency and making it highly practical.

[0018] 2. When the tension adjustment plate needs to be moved, the servo motor is started, which drives the lead screw to rotate. The lead screw is screwed to the lead screw nut on the floating connecting seat, thereby driving the floating connecting seat and the tension adjustment plate to move horizontally, which has a high degree of automation.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, an intelligent yarn frame device includes a yarn frame body 50, on which a plurality of yarn bobbins 51 wound with yarn are mounted. The yarn frame body 50 is provided with a plurality of parallel unwinding plates 52, and the parallel unwinding plates 52 have a plurality of yarn guide holes 53 facing the yarn bobbins 51. Below the parallel unwinding plates 52, there is a tension component base plate 54 and a yarn probe fixing seat 55 fixedly connected to the yarn frame body 50. The tension component base plate 54 is provided with a multi-head yarn guide tension control component 56 for controlling the tension of multiple strands of yarn. The yarn probe fixing seat 55 is provided with a multi-head yarn guide breakage detection structure 57, and the multi-head yarn guide breakage detection structure 57 is positioned corresponding to the multi-head yarn guide tension control component 56.

[0029] In this embodiment, during use, several yarn bobbins 51 with wound yarn are placed on the yarn frame body 50. The yarn passes through the yarn guide holes 53 of the parallel unwinding plates 52 and then down through the multi-head yarn tension control assembly 56. First, the yarn is guided by the multi-head yarn tension control assembly 56, and then the tension of the yarn is controlled by the tension gate structure, realizing simultaneous control of the tension of multiple yarns. Then, the yarn is guided by the multi-head yarn breakage detection structure 57, and then down through the yarn probe structure to monitor whether the multiple yarns are broken in real time. This device can simultaneously control the tension of multiple yarns and simultaneously monitor whether the multiple yarns are broken, solving the problem that the tension and breakage of a single yarn can only be controlled by a single gate and a single yarn probe, greatly improving efficiency and making it highly practical.

[0030] Combination Figure 1-6As shown, the multi-head guide wire tension control assembly 56 includes a tension adjustment plate 58 disposed on the tension assembly base plate 54, which can reciprocate linearly in the horizontal direction. The tension adjustment plate 58 is provided with a plurality of first gate fixing seats 59, and a floating gate 60 is screwed onto the first gate fixing seats 59. The tension assembly base plate 54 is provided with a plurality of second gate fixing seats 61, and a fixed gate 62 is screwed onto the second gate fixing seats 61. The floating gate 60 can reciprocate linearly along one end close to or away from the fixed gate 62. The floating gate 60 and the fixed gate 62 are facing each other and staggered. When the floating gate 60 and the fixed gate 62 are closed, the gate plates of the floating gate 60 and the gate plates of the fixed gate 62 abut against each other in an alternating manner.

[0031] In this embodiment, when it is necessary to control the tension of the passing yarn, the tension adjusting plate 58 is moved to the left, which drives the first gate fixing seat 59 and the floating gate 60 to move closer to the fixed gate 62. When the floating gate 60 and the fixed gate 62 are closed, the gate plates of the floating gate 60 and the gate plates of the fixed gate 62 are interleaved and abutted, thereby realizing the simultaneous control of the tension of multiple yarns, which is highly efficient.

[0032] The tension assembly base plate 54 is provided with a motor base 63 and a servo motor 64. A lead screw 65 is connected to the rotating shaft of the servo motor 64. A floating connecting seat 66 is installed on the tension adjustment plate 58. The lead screw 65 passes through the floating connecting seat 66, and the floating connecting seat 66 and the lead screw 65 are screwed together by a lead screw nut 67.

[0033] In this embodiment, when the tension adjustment plate 58 needs to be moved, the servo motor 64 is started, which drives the lead screw 65 to rotate. The lead screw 65 is screwed to the lead screw nut 67 on the floating connecting seat 66, thereby driving the floating connecting seat 66 and the tension adjustment plate 58 to move horizontally, which has a high degree of automation.

[0034] Combination Figure 5 As shown, the motor base 63 is provided with a positioning pin 68, which is positioned opposite to the clearance notch of the lead screw nut 67. The tension assembly base plate 54 is provided with a pretension spring 69 connected to the floating connecting seat 66.

[0035] In this embodiment, during the movement of the floating connecting seat 66, the positioning pin 68 and the clearance notch of the lead screw nut 67 can achieve a limiting effect, and the pretension spring 69 can provide a rebound force.

[0036] The tension assembly base plate 54 is also provided with a plurality of upper guide wire ceramic seats 70, and the upper guide wire ceramic seat 70 is provided with an upper guide wire ceramic ring 71, and the upper guide wire ceramic ring 71 is provided with an upper guide wire hole 72.

[0037] In this embodiment, the upper guide ceramic seat 70 is used to install and fix the upper guide ceramic ring 71, and the yarn is guided through the upper guide hole 72 of the upper guide ceramic ring 71.

[0038] The multi-head guide yarn breakage detection structure 57 includes a plurality of yarn probes 73 disposed on the yarn probe fixing seat 55, and a lower guide yarn pressure roller 74 mounted on the yarn probe fixing seat 55 is provided between the yarn probes 73 and the yarn guide hole 53.

[0039] In this embodiment, the yarn after tension control is guided to the yarn detector 73 through the lower guide roller 74. Several yarn detectors 73 monitor the multi-strand yarn in real time to check for breakage. The degree of automation is high. Those skilled in the art should understand that the yarn detector 73 is an existing device, and its internal structure and working principle are not the focus of this patent, so they will not be described in detail.

[0040] Combination Figure 4 As shown, the lower guide wire pressure roller component 74 includes a plurality of guide wire ceramic rod seats 75 and a wire pressure roller 76 disposed on the guide wire fixing seat 55. The guide wire ceramic rod seats 75 are equipped with guide wire ceramic rods 77, and the guide wire ceramic rods 77 have guide wire claw bodies 78.

[0041] In this embodiment, the guide rod seat 75 is used to install and fix the guide rod 77. After the yarn tension is controlled, the yarn is guided by the guide claw 78 of the guide rod 77 to the conductor pressure roller 76, and then sent to the probe 73 for monitoring.

[0042] Combination Figure 1 As shown, the yarn frame body 50 is provided with a plurality of insert rods 79 for fixing the yarn bobbin 51, and the axis of the insert rod 79 coincides with the center line of the yarn guide hole 53.

[0043] In this embodiment, the insertion rod 79 is used to install and fix the yarn bobbin 51. The center line of the insertion rod 79 coincides with the center line of the yarn guide hole 53, and the accuracy of the guide wire is high.

[0044] The working principle of this utility model is as follows:

[0045] During use, several yarn bobbins 51 with wound yarn are placed on the insert rods 79 on the yarn frame body 50. The insert rods 79 are used to install and fix the yarn bobbins 51. The axis of the insert rods 79 coincides with the center line of the yarn guide hole 53, ensuring high yarn guide accuracy. The yarn passes through the yarn guide hole 53 of the parallel unwinding plate 52 and then passes down through the upper guide hole 72 of the upper guide ceramic ring 71 for yarn guidance. When it is necessary to control the tension of the passing yarn, the tension adjusting plate 58 is moved to the left, causing the first gate fixing seat 59 and the floating gate 60 to move closer to the fixed position. One end of the fixed gate 62 moves, and when the floating gate 60 and the fixed gate 62 close, the gate plates of the floating gate 60 and the gate plates of the fixed gate 62 abut against each other, thereby achieving simultaneous control of the tension of multiple yarn strands, which is highly efficient. The guide rod seat 75 is used to install the fixed guide rod 77. After the yarn tension is controlled, the guide rod 77 guides the yarn through the guide claw 78, guiding the yarn to the conductor pressure roller 76, and then feeding it into the yarn detector 73 for real-time monitoring of whether the multiple yarn strands are broken. The degree of automation is high.

[0046] When the tension adjusting plate 58 needs to be moved, the servo motor 64 is activated, which drives the lead screw 65 to rotate. The lead screw 65 is screwed onto the lead screw nut 67 on the floating connecting seat 66, thereby causing the floating connecting seat 66 and the tension adjusting plate 58 to move horizontally. The automation level is high.

[0047] During the movement of the floating connecting seat 66, the positioning pin 68 and the clearance notch of the lead screw nut 67 can achieve a limiting effect, and the pretension spring 69 can provide a restoring force.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
