[0003] The Chinese patent application with publication number CN116145317A discloses a tension type warp yarn guide frame. When the warp yarn is unwound, the warp yarn is first collected and combed by the yarn collecting frame, then guided and transported by the yarn feeding roller, tension roller and yarn outlet roller in turn, and then transported to the subsequent weaving machine head position for subsequent weaving work.

[0004] This kind of way has obvious lag in response to tension fluctuation, and it is difficult to adjust in real time according to the speed change of the production line. When the production line speeds up or slows down, the mechanical adjusting structure cannot quickly balance the tension, which may cause the glass fiber yarn to break due to sudden increase of tension, or cause stacking, winding deviation due to insufficient tension, and finally cause uneven distribution of fiber in the composite rod and substandard strength, which seriously restricts the continuous and stable operation of the automatic production line.

DETAILED DESCRIPTION

[0016] The two embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0017] First embodiment: Figures 1-4 And Figures 9-10 A fiber yarn roll mounting frame for a composite material rod automatic production line is shown, comprising a yarn frame mechanism, a tension monitoring and adjusting mechanism, a tension calculation system and a motor power control system; The yarn frame mechanism is used to install multiple yarn rolls and enable the yarn rolls to rotate independently to release yarn; The tension monitoring and adjusting mechanism can measure yarn tension and adjust yarn tension; The tension calculation system is electrically connected with the tension monitoring and adjusting mechanism, and calculates yarn tension deviation value according to received yarn tension data; The motor power control system is electrically connected with the tension calculation system, and generates adjustment instructions according to the tension deviation value to enable the tension monitoring and adjusting mechanism to adjust yarn tension; The yarn frame mechanism comprises a front frame 1, a plurality of cross plates 101 are fixedly connected between both ends of the front frame 1, a plurality of mounting holes 102 are evenly distributed on the cross plates 101, a bottom plate 103 is fixedly connected to one end of the cross plate 101 close to the mounting hole 102, a shaft 104 is rotatably connected to the middle part of the bottom plate 103, a yarn roller 105 is fixedly connected to one end of the shaft 104, the mounting holes 102 on the plurality of cross plates 101 are distributed in a rectangular grid shape, and the yarn roller 105 is fixedly connected to one end of the shaft 104.

[0018] The tension monitoring and adjusting mechanism is one of a high-precision regulator and a cross regulator.

[0019] The high-precision regulator comprises a rotary motor 4 and a monitoring box 5, a plurality of rotary motors 4 are provided, the plurality of rotary motors 4 and the plurality of yarn rollers 105 one-to-one correspond, the rotary motor 4 and the bottom plate 103 are fixedly connected, the output end of the rotary motor 4 and one end of the shaft 104 are fixedly connected, a plurality of tension sensors 501 are fixedly connected in the monitoring box 5, the plurality of tension sensors 501 correspond to the plurality of yarn rollers 105 one-to-one, and the tension sensor 501 and the rotary motor 4 are electrically connected.

[0020] Through the above setting, the yarn is connected with the tension sensor 501, and the tension sensor 501 can monitor the yarn tension, and the tension calculation system calculates the tension deviation value according to the yarn tension. When the yarn tension is abnormal, the motor power control system controls the corresponding rotating motor 4 to drive the yarn roller 105 to rotate, and adjusts the yarn tension. The above setting, the tension sensor 501 can more directly measure the yarn tension and feedback to the rotating motor 4, so that the yarn tension adjustment is more rapid and accurate.

[0021] Second embodiment: Figures 1-8 A fiber yarn roll mounting frame for an automatic composite rod production line is shown, which is different from the first embodiment. The cross regulator includes a horizontal adjustment device and a vertical segmentation device. The horizontal adjustment device includes a side pipe 2 fixedly connected with a bottom plate 103. One end of the side pipe 2 is rotatably connected with a driven wheel 203. One end of the driven wheel 203 is fixedly connected with a driven friction plate 206. The horizontal adjustment device further includes a torsion sensor 204 and an adjusting motor 205. The torsion sensor 204 and the adjusting motor 205 are respectively fixedly connected with two ends of a horizontal plate 101. The output ends of the torsion sensor 204 and the adjusting motor 205 are fixedly connected with rotating wheels 202. The rotating wheels 202 are rotatably connected with a transmission belt 201. The transmission belt 201 is in transmission connection with a plurality of driven wheels 203 between the torsion sensor 204 and the adjusting motor 205.

[0022] The vertical segmentation device includes a rear frame 3. One end of the rear frame 3 is fixedly connected with a plurality of telescopic cylinders 301. The plurality of telescopic cylinders 301 correspond to a plurality of rows of yarn rollers 105. The output end of the telescopic cylinder 301 is fixedly connected with a vertical plate 302. One end of the vertical plate 302 is fixedly connected with a plurality of ring frames 303. The plurality of ring frames 303 correspond one-to-one to the plurality of yarn rollers 105. One end of the ring frame 303 is fixedly connected with an intermediate sleeve 304. The inner wall of the intermediate sleeve 304 is rotatably connected with a transmission sleeve 305. The transmission sleeve 305 has a sliding groove 306 in the inside. One end of the transmission sleeve 305 is fixedly connected with a driving friction plate 307 matched with the driven friction plate 206.

[0023] One end of the rotating shaft 104 is located inside the transmission sleeve 305. The outer wall of the rotating shaft 104 is fixedly connected with a sliding block 106. The sliding block 106 is in sliding connection with the sliding groove 306.

[0024] When the rotating shaft 104 rotates, the transmission sleeve 305 is rotated through the sliding block 106 and the sliding groove 306. When a single vertical segmentation device is started, the telescopic cylinder 301 drives the transmission sleeve 305 to move towards the passive wheel 203 through the vertical plate 302, so that the driving friction plate 307 and the passive friction plate 206 are attached. At this time, the transmission sleeve 305 drives the passive wheel 203 to rotate, and the passive wheel 203 drives the rotating wheel 202 to rotate through the transmission belt 201 when rotating. The rotating wheel 202 can measure the yarn tension through the torsion sensor 204.

[0025] When the yarn is drawn out from the yarn roller, the tension of the yarn will generate resistance to the rotation of the yarn roller. This resistance will be transmitted to the torsion sensor 204 through the transmission structure, such as the passive wheel 203 and the transmission belt 201, so that the torsion of the torsion sensor 204 changes with the change of the yarn tension. After the torsion sensor 204 directly detects the torsion value, the actual tension of the yarn can be indirectly calculated through the preset torsion-tension corresponding relationship and the fixed transmission ratio and other parameters. The tension calculation system calculates the yarn tension deviation value according to the yarn tension data.

[0026] When one of the plurality of vertical segmentation devices is started, the plurality of horizontal adjustment devices can measure the yarn tension of the column corresponding to the started single vertical segmentation device. When the plurality of vertical segmentation devices are alternately and cyclically started, the yarn tension of each column can be measured.

[0027] When the yarn tension is abnormal, the motor power control system starts the adjusting motor 205 to drive the yarn roller 105 to rotate according to the yarn tension deviation value obtained by the tension calculation system, and adjusts the tension of the yarn roller 105. After adjustment, the plurality of vertical segmentation devices continue to be alternately and cyclically started.

[0028] Through the above setting, only one torsion sensor 204 for monitoring the yarn tension and one adjusting motor 205 for adjusting the yarn tension are arranged on each horizontal adjustment device, and the plurality of vertical segmentation devices are used in cooperation, so that the yarn tension on the plurality of yarn rollers 105 can be measured in turn.

[0029] The rotating motor 4 and the adjusting motor 205 are both servo motors. The servo motor realizes the closed-loop feedback of position and speed through the encoder, can accurately execute the adjustment instruction of the control system, ensures that the error of tension adjustment is extremely small, can stabilize the glass fiber yarn tension in the preset range, avoids the tension fluctuation caused by insufficient adjustment accuracy, and ensures the uniform distribution of the fiber of the composite material rod.

[0030] The servo motor has rapid dynamic response (millisecond level) for starting, braking and speed switching. When the production line speed changes or the tension monitoring system feedbacks deviation, the output torque can be quickly adjusted to balance the tension in time. For example, when the production line speed increases, the yarn roller release speed can be instantaneously increased to avoid sudden tension increase, effectively reducing the risk of glass fiber breakage due to high brittleness.

[0031] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to the scope, and various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
