Description
Technical Field
[0001] This application relates to the field of yarn twisting frame technology, and in particular to a yarn twisting frame device that prevents yarn strands from colliding. Background Technology
[0002] The twisting frame is an important component of textile machinery. It is used to support and guide the yarn in the twisting machine to ensure that the yarn can be transmitted stably and orderly during the processing. The twisting frame is mainly composed of a frame, a yarn tube support, and an adjustment mechanism. The frame, as the foundation of the entire frame, is usually designed with a cast frame to ensure stability and load-bearing capacity. The yarn tube support is used to fix the yarn tube. However, in practical applications, the twisting frame also has some disadvantages. The following are some of the main disadvantages of the twisting frame: (1) Easy to break yarn: During high twist operation, the yarn is prone to breakage mainly due to the friction between the yarns. Especially when changing the unwinding yarn, if the yarn diameter is too large, it will lead to increased tension and increase the risk of yarn breakage. (2) Yarn tube is prone to shaking: During the rotation of the yarn tube, the yarn tube is prone to shaking due to the instability of the fixing method. This not only affects the quality of the yarn, but may also lead to further damage to the yarn. Therefore, the above technical problems need to be solved. Summary of the Invention

[0029] Example 2: The technical solution is basically the same as that of Example 1, except that, as Figures 11 to 16 As shown, the drive assembly includes a traveling roller 17 longitudinally rotating on both sides of the upper part of the mounting base 6 and a servo motor 15 located on the upper part of the front end face of the mounting base 6. The front end of the traveling roller 17 is coaxially fixed to the drive shaft of the servo motor 15. The outer wall of the traveling roller 17 rolls against the top of the crossbeam 5. Friction wheel rings are fixedly sleeved on the roller body at both the front and rear ends of the middle part of the traveling roller 17.

The ranging component includes a buffer block 20 on the upper part of both side walls of the mounting seat 6, a mounting groove opened on the outer end face of the buffer block 20, and a ranging sensor 28 inside the mounting groove.

Both ends of the crossbeam 5 have positioning holes vertically opened at their tops that cooperate with the limiting screw 26. The top end of the limiting screw 26 extends from the positioning hole at the end of the crossbeam 5 and is screwed with a locking nut 27. The locking nut 27 is pressed against the top of the crossbeam 5. An overlapping plate for improving the connection strength is also fixed to the top of the outer end of the crossbeam 5. By setting up the connecting assembly, it is easy to realize the purpose of disassembling the crossbeam 5 as a whole, which can effectively improve the efficiency of replacing and repairing the crossbeam 5, and improve the stability and end support of the crossbeam 5 after installation.
[0031] Working principle: In this embodiment, the present invention also proposes a method for using a twisting frame device to prevent yarn strand collision, including the following steps: Step 1: First, connect the servo motor 15, electric push rod 16, and ranging sensor 28 to the controller inside the control cabinet 2 via wires. Then, connect the electrical components inside the control cabinet 2 to the external power supply. Next, use the mounting tube 11 and the stabilizing wheel 14 to stably install the mounting base 6 on the top of the crossbeam 5. Then, use the positioning assembly to limit and fix the rear end of the mounting tube 11 used to limit the mounting base 6. At this time, the positioning rod 19 is inserted into the positioning groove at the rear end of the mounting tube 11 to limit and fix the mounting tube 11, thereby enabling the mounting base 6 to be stably slidably installed on the top of the crossbeam 5. Step 2: After the mounting base 6 is installed, the idler roller 12 used to support the yarn bobbin is also installed inside the front and rear ends of the mounting tube 11. Due to the principle of repulsion between the like poles of the magnetic ring plate 22 and the magnetic ring block 23, friction between the turntable 13 and the mounting tube 11 can be avoided. Then, the anti-detachment ring is unscrewed from the outer end of the idler roller 12, and the yarn roll is attached to the idler roller 12. The anti-detachment ring is screwed back onto the idler roller 12 to limit the yarn bobbin. Then, one end of the yarn is passed through the guide hook 30 and through the yarn guide wheel 8 and the rotating roller 10 to complete the yarn guiding operation. Step 3: Next, based on the position of the installed yarn bobbins, in order to avoid collisions between the yarns unwound from the yarn bobbins, the distance sensors 28 on both sides of the mounting base 6 can automatically monitor the distance between the yarn bobbins installed at the front and rear ends of each mounting base 6 in real time, and transmit the distance data to the control host inside the control cabinet 2 through the distance sensors 28. Then, the control host automatically analyzes the distance between each mounting base 6 and the yarn bobbins to determine whether this distance data will affect the yarn collision during unwinding. If it is determined that the measured data cannot meet the unwinding space requirements, the drive component on the corresponding mounting base 6 is activated, and the drive component on the mounting base 6 drives the mounting base 6 to move laterally on the crossbeam 5 for adjustment. Step 4: When adjusting the lateral spacing of the unwinding space of the mounting seat 6, the servo motor 15 is started to drive the traveling roller 17 to rotate. The rotation of the traveling roller 17 can drive the mounting seat 6 to move laterally on the crossbeam 5, thereby enabling the mounting seats 6 installed on each upper and lower crossbeam 5 to be automatically staggered, so as to meet the yarn bobbin spacing after the yarn is gradually unwound, and effectively avoid the unwound yarn from colliding. Step 5: After the horizontal adjustment of the mounting base 6 that needs to be adjusted is completed, the locking plate 21 is lowered by starting the electric push rod 16. The lowered locking plate 21 can make the stop strip engage inside the rack plate 24, thereby achieving the purpose of automatic locking and positioning of the adjusted mounting base 6, which can effectively improve the positioning effect of the yarn bobbin after anti-collision adjustment.
