Description

Technical Field

[0001] The utility model relates to the technical field of glass yarn processing equipment, in particular to a glass yarn drawing device. Background Art

[0002] Glass yarn, also known as Bali yarn or crystal yarn, is a thin and transparent fabric woven with plain weave. It usually uses fine combed and twisted yarn with low warp and weft density, so it is light, thin and transparent. When glass yarn is used in optical cables, it can make the optical cable structure compact and increase the tensile and compressive strength of the optical cable; it ensures that the optical cable can still work normally under high or low temperature conditions and adapt to more harsh environments.

[0003] When processing glass yarn, a motor is usually used to drive the winding drum to rotate, and the glass yarn is pulled and wound. At present, when fixing the glass yarn, one end of the glass yarn is generally tied to the winding drum.

[0004] However, when the glass yarn is used again after being wound up, the binding knot is often difficult to untie. At this time, the staff needs to cut the glass yarn and clean up the remaining glass yarn, which undoubtedly causes waste of materials and reduces the utilization rate of the glass yarn.

[0005] For this reason, we propose to design a glass yarn pulling device. Utility Model Content

[0027] See also Figure 1-5The utility model provides a glass yarn pulling device, including a bracket 1, a motor 2 is fixedly connected to one side of the top of the bracket 1, and the driving shaft of the motor 2 passes through the bracket 1 and is fixedly connected to a pulling shaft 3. Among them, a partition 4 is fixedly connected to the outer wall of one end of the pulling shaft 3 close to the motor 2, and the cross section of the partition 4 is arranged in a circular ring shape, which is convenient for isolating the glass yarn pulling shaft 3 from the motor 2 to avoid the risk of the yarn being wound outside the motor 2.

[0028] An end cover 5 is provided at the end of the wire pulling shaft 3, and a threaded rod 501 threadedly connected to the wire pulling shaft 3 is fixedly connected at the center of the end cover 5. A limiting tube 502 is fixedly connected at the edge of the end cover 5. The inner wall of the limiting tube 502 fits smoothly with the outer wall of the positioning strip 6, which makes it easy to fix the wire pulling tube 7 between the partition 4 and the limiting tube 502.

[0029] A positioning strip 6 is fixedly connected to the outer wall of the wire-pulling shaft 3, and a wire-pulling drum 7 is sleeved on the outer wall of the wire-pulling shaft 3. A limiting groove 8 corresponding to the positioning strip 6 is provided on the inner wall of the wire-pulling drum 7. The limiting groove 8 is slidably connected to the positioning strip 6 to facilitate the connection between the wire-pulling drum 7 and the wire-pulling shaft 3. The transmission is carried out by fitting the positioning strip 6 and the limiting groove 8, so that the motor 2 can synchronously drive the wire-pulling drum 7 to rotate.

[0030] A groove 9 is formed on the outer wall of the wire drawing drum 7 , a pressing plate 10 is arranged inside the groove 9 , one end of the pressing plate 10 is fixedly connected to a fixing rod 11 , and the other end of the pressing plate 10 is provided with a telescopic rod 12 .

[0031] One end of the groove 9 is provided with a socket 15 corresponding to the fixed rod 11, and the other end of the groove 9 is provided with a through hole 16 corresponding to the telescopic rod 12. The fixed rod 11 is first inserted into the socket 15, and then the telescopic rod 12 is pressed into the through hole 16, so as to fix the pressure plate 10 and position the glass yarn.

[0032] An active groove 13 is formed at one end of the pressing plate 10 close to the telescopic rod 12 , and a spring 14 is fixedly connected between the active groove 13 and the telescopic rod 12 .

[0033] In this embodiment, anti-skid rubber strips 17 are fixedly connected at the bottom center of the groove 9 and on both sides of the pressure plate 10. The anti-skid rubber strips 17 are made of wear-resistant rubber material. When pressed on the top of the glass yarn, they can provide sufficient friction to fix the glass yarn. At the same time, the operation of taking and fixing is simple and will not cause damage to the glass yarn.

[0034] When in use, firstly, the wire drawing drum 7 to be collected is inserted into the wire drawing shaft 3 through one end thereof, so that the positioning strip 6 is correspondingly matched with the limiting groove 8, and then the glass yarn outside the wire drawing drum 7 is installed.

[0035] During installation, the staff inserts a finger into the through hole 16 and pushes out the telescopic rod 12, so that the pressing plate 10 can be removed from the groove 9, and then one end of the glass yarn is placed into the groove 9, and the pressing plate 10 is pressed back to press the glass yarn between the pressing plate 10 and the groove 9, and finally the telescopic rod 12 is pressed back into the through hole 16 to fix the pressing plate 10.

[0036] After the glass yarn is installed, multiple wire drawing drums 7 can be installed on the outside of the wire drawing shaft 3 in turn. Note that the positions of the pressure plates 10 must be in a straight line to ensure that the wire drawing and winding length of each glass yarn on the wire drawing drum 7 is consistent, ensuring that the wire drawing and winding effect of each wire drawing drum 7 remains consistent.

[0037] Driven by the motor 2, the wire drawing shaft 3 is driven to rotate, and the multiple wire drawing drums 7 are synchronously driven to rotate to draw and reel the glass yarn. After the reeling is completed, the glass yarn is disconnected, and the end cover 5 is screwed off, and the multiple wire drawing drums 7 can be removed in sequence.

[0038] When the glass yarn is used subsequently and is exhausted, one only needs to press the telescopic rod 12 on the side of the wire drawing drum 7 to disengage it from the through hole 16, and then the pressing plate 10 can be opened to completely take out the glass yarn without cutting the glass yarn. This not only makes full use of the glass yarn and avoids material waste, but also provides convenience for the subsequent drawing and winding of the glass yarn.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
