[0003] In the current glass fiber kiln drawing process, there are two drawing forming methods, one is the cylindrical direct yarn drawing method, the other is the saddle-shaped cake yarn drawing method. Each machine head must be equipped with an upper wire ring, which pushes the yarn out of the front upper wire ring through the push rod to change the head. After the head is replaced or the tube is changed, the push rod is retracted. Under the action of the push rod and the rotation of the machine head, the yarn exists in a spiral shape between the two winding tubes to form a "yarn ball line". Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0018] Example: Figure 1 and Figure 2As shown, a multifunctional wire pushing and screw blocking mechanism of a wire drawing machine includes a supporting crossbeam 4, a motor synchronous pulley 1 is provided on one side of the supporting crossbeam 4, a driven synchronous pulley 6 is provided on the other side of the supporting crossbeam 4, a synchronous belt 5 is provided between the motor synchronous pulley 1 and the driven synchronous pulley 6, a servo motor 13 is provided at the rear end of one side of the supporting crossbeam 4, which is connected and fixed to the motor synchronous pulley 1 in an embedded transmission manner, and a mounting plate 2 is provided between the servo motor 13 and the ratchet sliding assembly 10, which is welded and fixed to the supporting crossbeam 4 in a sleeve manner. A pulley shaft 8 is provided on the other side of the supporting crossbeam 4, which is supported in an embedded manner with the driven synchronous pulley 6, and a bearing 7 is provided between the pulley shaft 8 and the driven synchronous pulley 6. A ratchet sliding assembly 10 is provided at the lower end of the supporting beam 4 and is slidably connected and fixed to the supporting beam 4. A synchronous belt pressure block 9 is provided between the upper end of the ratchet sliding assembly 10 and the synchronous belt 5. An upper screw rod 3 is provided at the rear end of the supporting beam 4 and is connected and fixed to the ratchet sliding assembly 10. A lower stop screw rod 12 is provided at the lower end of the ratchet sliding assembly 10. A lower stop screw rod fixing seat 11 is provided between the ratchet sliding assembly 10 and the lower stop screw rod 12.
[0019] The ratchet sliding assembly 10 includes a slider seat 14, which is composed of an inner slider assembly and an outer slider assembly, and both the inner slider assembly and the outer slider assembly are composed of a slider pad 15, a slider 16 and a slider pressure plate 17. A slider pad 15 is provided between the upper end of the slider 16 and the synchronous belt pressure block 9, and a slider pressure plate 17 is provided between the lower end of the slider 16 and the ratchet pin baffle 18. A ratchet pin baffle 18 connected and fixed to the outer slider assembly is provided at the lower end of the slider seat 14, a pawl seat 21 connected and fixed to the inner slider assembly is provided on the side of the ratchet pin baffle 18, a ratchet 19 is provided between the ratchet pin baffle 18 and the pawl seat 21, and a pawl 20 movably engaged with the ratchet 19 is provided between the ratchet pin baffle 18 and the ratchet 19.
[0020] Since the diameter of the yarn roll is large, it is necessary to control the yarn to fall into fewer deep grooves, so the wire push and stop screw mechanism adopts a servo motor 13, which is composed of a synchronous belt synchronous wheel, a front and rear double slider seat 14, an upper screw rod 3, a lower stop screw rod 12, a ratchet sliding assembly 10, etc. The lower stop screw rod 12 is installed on the outer slider assembly and fixed with the synchronous belt 5 and moves synchronously. When the full drum is changed, the lower stop screw rod 12 is pushed out at high speed to increase the spiral angle of the yarn winding to the deep groove across the yarn ball spacing. The upper stop screw rod 3 is installed on the inner slider assembly, and the inner slider assembly is provided with a ratchet sliding assembly 10. When the wire push and stop screw mechanism drives the outer slider assembly to press toward the rear end once, the inner and outer sliders 16 are self-locked, and then pressed again to unlock and disengage the outer slider. When the slow pull is automatically pulled, the inner and outer sliders 16 are pressed backward to self-lock, and the upper stop screw rod 3 moves with the synchronous belt 5 to push all the yarn on the side of the wire drawing machine to the front end for easy wire drawing. When the upper head is changed, the wire push and stop screw mechanism can cooperate with the auxiliary upper head change mechanism to control the wool yarn and reduce the upper head change yarn. Changing the original single pneumatic structure to an electric one can save energy, reduce consumption and reduce pollution.
[0021] In summary, the multifunctional wire pushing and blocking screw rod mechanism of the wire drawing machine has the characteristics of compact structure, good operation stability and complete functions. It solves the problem of large amount of yarn falling into deep grooves. When the slow pulling automatic head is put on, all the yarn on the side of the wire drawing machine is pushed out of the front end for easy wire drawing. When changing the head, the wool yarn is controlled to reduce the yarn for changing the head.
