Description

Technical Field

[0001] The invention relates to the technical field of wire drawing, in particular to a wire drawing method of a wire drawing machine with a grooved drum capable of being positionable and reciprocating. Background Art

[0002] As a basic raw material, glass fiber composite materials have been widely used in transportation, electronic information, aerospace, infrastructure, medical care, environmental protection and energy with the development of processing technology and auxiliary material technology. Glass fiber and its products are increasingly valued by people for their excellent functional material properties. In the process of glass fiber drawing, the indispensable equipment is the glass fiber drawing machine, which is a mechanical equipment that draws the molten glass into fiber filaments at high speed and winds them into fiber rolls according to a certain pattern.

[0003] The existing glass fiber drawing machine is generally equipped with two sets of rotating heads. During the production process, when one set of heads is full of yarn balls, the other set of empty yarn heads is rotated to the working position by rotating the two sets of heads. At this time, the workers need to manually pull the fiber filaments to the empty yarn heads in the working position, and then remove the heads full of yarn balls and replace them with new empty yarn tubes. However, since the yarn balls pulled by the current drawing machines are relatively small, the time it takes to fully pull a yarn ball is very short, and this time is not enough for the workers to complete the unloading and sleeve of the tubes. This results in the need to stop the machine after each yarn ball is fully pulled to ensure the workers' operating time, which seriously affects the production efficiency. Furthermore, the workers need to continuously pull the yarn, unload the tubes and sleeve, which greatly increases the labor intensity of the workers. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a wire drawing method of a wire drawing machine with a displaceable and reciprocating groove drum, which can overcome the above shortcomings of the prior art.

The turntable 22 drives two groups of machine heads 23 to rotate for working switching, and the sliding bracket 33 and the sliding seat 35 drive the groove drum 10 to move back and forth along the length direction of the wire drawing machine machine head 23 and to move horizontally towards or away from the machine head 23 in the plane where the groove drum 10 and the wire drawing machine head 23 are located.

[0032] The specific structure is that a base plate 21 is arranged on the side of the frame 20, a turntable 22 is rotatably arranged on the base plate 21, two groups of machine heads 23 are centrally symmetrically distributed on the turntable 22, and a driving component for driving the turntable 22 to rotate is arranged in the frame 20.

The sliding bracket 33 includes a vertical plate 335 and a horizontal plate 336. The horizontal plate 336 is arranged at the top of the vertical plate 335. A support plate 337 is arranged between the vertical plate 335 and the horizontal plate 336. The horizontal plate 336 is supported by the support plate 337 to improve the stability of the horizontal plate 336. The first slide rail 32 is horizontally arranged on the inner side of the mounting plate 31. The vertical plate 335 of the sliding bracket 33 is slidably arranged on the first slide rail 32 through a slider. A rack 331 parallel to the first slide rail 32 is provided on the vertical plate 335 of the sliding bracket 33, and a servo motor 311 is provided on the inner side of the mounting plate 31 through a connecting plate, and a gear 312 is connected to the output shaft of the servo motor 311, and the gear 312 is meshed with the rack 331. The servo motor 311 drives the gear 312 to rotate, thereby driving the rack 331 and the vertical plate 335 to slide on the first slide rail 32, thereby causing the entire sliding bracket 33 to slide along the first slide rail 32.

[0034] A second slide rail 34 is arranged on the transverse plate 336 of the sliding bracket 33, and the length direction of the second slide rail 34 is parallel to the length direction of the machine head 23.

A nut slider 334 is spirally arranged on the screw rod 332, and the nut slider 334 is fixedly connected to the sliding seat 35. In this way, when the screw rod 332 rotates, the nut slider 334 will not rotate with the screw rod 332 under the action of the sliding seat 35, so that it will move along the length direction of the screw rod 332 with the sliding seat 35, and then drive the sliding seat 35 to slide on the second slide rail 34.

[0036] The wire drawing method of the wire drawing machine with a groove drum that can be displaced and reciprocated comprises the following steps:

[0037] S1. Put a number of empty yarn tubes on the heads 23 of the wire drawing machine; initially, empty yarn tubes are put on both sets of heads 23, one set of heads 23 is in the wire drawing working position, and the other set of heads 23 is in the idle position waiting for replacement.

[0038] S2, move the groove drum 10 to the front end of the wire drawing machine head 23 close to the working position of the head 23, and start drawing wire on the empty yarn ball at the front end of the head 23; specifically, the rotating motor 333 is started to drive the screw rod 332 to rotate, so that the nut slider 334 drives the sliding seat 35 to slide on the second slide rail 34 to move the groove drum 10 to the front end of the head 23, and then the servo motor 311 is started to drive the gear 312 to rotate, so that the rack 331 drives the sliding bracket 33 to slide along the first slide rail 32 to get closer to the head 23, so that the groove drum 10 reaches the working position close to the head 23; then the driving motor 12 drives the groove drum 10 to rotate to enter the wire drawing link.

[0039] S3. After the above-mentioned empty yarn ball is fully drawn, the groove drum 10 moves in the direction away from the wire drawing machine head 23 in the plane where it and the wire drawing machine head 23 are located, and then moves along the length direction of the wire drawing machine head 23 to a position flush with the next empty yarn tube, and then moves in the direction close to the head 23 in the plane where it and the wire drawing machine head 23 are located to the working position, and starts to draw wire on the corresponding empty yarn ball; the specific driving method is the same as step S2, the reciprocating motion of the groove drum 10 along the length direction of the wire drawing machine head 23 is completed by the rotating motor 333 driving the lead screw 332 slider mechanism; the lateral movement of the groove drum 10 in the plane where the groove drum 10 and the wire drawing machine head 23 are located is completed by the servo motor 311 driving the gear 312 rack 331 mechanism.

[0040] S4, and so on, until all the empty yarn balls on the machine heads 23 are pulled full; several empty yarn balls on the same group of machine heads 23 can be completed continuously under the action of the grooved drum 10, without manual intervention, thus freeing up manpower.

[0041] S5, rotating the machine head 23, so that the machine head 23 of another group with empty yarn balls reaches the working position, and the machine head 23 with full yarn balls is turned to the idle position for unloading.

[0042] The above method, through the setting of the groove drum 10, enables a group of machine heads 23 to continuously draw multiple yarn balls at a time, thereby extending the working time of the machine heads 23, so that workers have enough time to perform tasks such as unloading and sleeve, and no frequent shutdown is required, which reduces the workers' operating time and improves production efficiency.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
