Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a multi-stroke screw-pushing mechanism for a wire drawing machine. Background Art

[0002] Glass fiber drawing machine is a mechanical equipment used to draw glass solution into fibers and wind them into fiber rolls according to a certain pattern. In the glass fiber production process, most of them use double-head automatic barrel-changing drawing machines, also called double-barrel automatic barrel-changing drawing machines.

[0003] In the glass fiber production process, since the drawing machine full barrel replacement and slow pull automatic head are to push the wire outward by pushing the wire rod, the wire is wound on the upper wire ring with a wire hook or a threaded tooth groove, which is also a superior upper wire ring structure in recent years. However, these two forms have the following defects:

[0004] 1) The V-groove upper wire ring plus the wire hook is more beneficial for large yarns. During automatic threading and automatic bobbin changing, the wire is pushed into the V-groove by the wire push rod and the wire hook can be easily introduced into the upper wire ring, which can also solve the problem of excessive winding on the upper head. However, it is not suitable for small yarns, because the glass fiber wire is relatively fragile at this time, so the wire breaks and the machine stops when switching at high speed.

[0005] 2) The thread tooth groove type is just the opposite. It is more favorable for small-sized silk threads. There is no obvious structural undulation, so the silk threads can be easily switched to another machine head through the delicate thread tooth grooves. However, when slow-pull automatic head feeding is adopted, the line speed is low and the fiber is relatively thick or large-sized silk threads cannot be automatically fed. In the case of slightly larger silk threads, the silk threads cannot be fully grasped, which affects the success rate. At present, some users can only install an independent second wire feeding mechanism with drive between the slow-pull and the machine head to speed up the storage of silk threads. The process structure is complicated, which not only takes up space but also affects the environment.

[0006] The prior art product, Chinese patent "A composite mechanism for automatic head and barrel changing of a glass fiber drawing machine", application number 2022216461544, the screw push rod stroke switching mechanism can only block the screw push cylinder from shortening its stroke by horizontally inserting the cylinder bumper to achieve two positions, but it has two defects. After pushing out the longest distance, it cannot be changed to a shorter distance position, and the other variable stroke is that the horizontally inserted bumper cannot be pulled out after it is inserted.

When the yarn is automatically put on by slow pulling, all the yarns on the side of the wire drawing machine are 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. The problem that large and small wires cannot be automatically put on and automatically changed on the same wire drawing machine is solved.

[0025] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] Example: Figure 1-5 As shown, a multi-stroke wire drawing machine push rod mechanism includes a wire drawing machine frame 1, and two machine heads 3 are provided at the front end of the wire drawing machine frame 1, and a yarn 4 wound with the machine head 3 is provided on the machine head 3, and a slow puller 6 wound with the yarn 4 is provided below the machine head 3. A composite upper wire ring 5 connected and fixed to the machine head 3 is provided at the front end of the machine head 3, and an upper wire ring V-shaped groove 12 is provided on the composite upper wire ring 5, and an upper wire ring thread groove 11 is provided between the upper wire ring V-shaped groove 12 and the machine head 3, and four upper wire hooks 13 are provided outside the upper wire ring V-shaped groove 12, which are distributed in an annular manner with equal spacing and are integrated with the outer circle of the composite upper wire ring 5. A push rod mechanism 2 is provided above the machine head 3 and is bolted and fixed to the wire drawing machine frame 1, and the push rod mechanism 2 drives the yarn 4 to complete the process of changing the barrel and putting on the head on the composite upper wire ring 5. The screw push rod mechanism 2 includes a screw push rod 9, and a guide support shaft sleeve 8 is provided between the screw push rod 9 and the end surface of the screw push rod mechanism 2. A multi-stroke drive assembly 7 is provided between the rear end of the screw push rod 9 and the wire drawing machine frame 1, and a push plate 10 is provided at the front end of the screw push rod 9 for movable crimping with the yarn 4.

[0027] The multi-stroke drive assembly 7 includes a wire pushing cylinder 15, a wire pushing rod locking seat 17 is provided between the lower end of the wire pushing cylinder 15 and the wire pushing rod 9, and the wire pushing cylinder 15 is provided with a cylinder slider 16, and the cylinder slider 16 drives the wire pushing rod 9 to reciprocate. A displacement double-rod cylinder 19 is provided at the lower front end of the wire pushing cylinder 15, which is screwed and fixed to the wire drawing machine frame 1, and a cylinder top block 18 is provided between the displacement double-rod cylinder 19 and the wire pushing rod locking seat 17, which is connected and fixed to the displacement double-rod cylinder 19. Buffers 14 are provided on both sides of the front and rear ends of the wire pushing rod locking seat 17, and the buffers 14 on both sides of the front end are slidably pressed with the cylinder top block 18, and the buffers 14 on both sides of the rear end are slidably pressed with the rear end of the wire pushing cylinder 15.

[0028] Working principle: The screw rod mechanism 2 is installed on the upper part of the wire drawing frame 1. When a head 3 at the front end of the wire drawing frame 1 is full, the screw rod mechanism 2 stretches and pushes the yarn 4 to the upper wire hook 13 outside the upper wire ring V-shaped groove 12. The yarn 4 is pulled by the slow pulling mechanism 6 to change the two heads 3 at the same time, so that the yarn 4 is introduced into the upper wire ring V-shaped groove 12 of the other head 3, and the yarn 4 and the upper head of the yarn 4 are cut off after the change of the barrel. Then the screw rod mechanism 2 shrinks, and the yarn 4 enters the upper wire ring thread groove 11 from the upper wire ring V-shaped groove 12, completing the process of changing the barrel and putting on the wire.

[0029] In summary, the multi-stroke screw-pushing mechanism of the wire drawing machine has the characteristics of compact structure, good operating stability and high utilization efficiency. The problem of a large amount of yarn falling into deep grooves has been solved. When the yarn is automatically put on by slow pulling, all the yarns on the side of the wire drawing machine can be pushed out to the front end for easy wire drawing. When changing the head, the wool yarn is controlled to reduce the yarn for changing the head. The problem that large and small silk threads cannot be automatically put on and automatically changed barrels on the same wire drawing machine has been solved. The screw-pushing stroke switching mechanism on the upper part of the machine head cooperates with the composite upper wire ring at the front end of the machine head and the slow-pull automatic upper wire mechanism under the machine head, so that large and small yarns can be automatically put on the different shaft segments on the composite upper wire ring during automatic putting on and automatic barrel changing. The wire switching winding solves the problem of a certain amount of yarn storage generated from the initial to high speed of the fine yarn drawing process. The different automatic yarn loading and automatic barrel changing mechanisms are simplified to improve the versatility of the wire drawing machine. The wire pushing cylinder is placed at the front end, and any control position is achieved through the position of the two cylinder strokes. The push position of the wire pushing cylinder is determined according to the wire pushing displacement double-rod cylinder, but the short-stroke cylinder is larger than the long-stroke cylinder. As long as the long-stroke cylinder is pushed out, the short-stroke cylinder can be pressed back to its stroke at any time to achieve any control position. The utility model is suitable for direct yarn and silk cake yarn drawing machines.
