Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a silk thread deoiling device. Background Art

[0002] Silk threads are used to make textile fabrics. They are usually wound onto paper rolls. To prevent the threads from sticking to each other on the rolls, a layer of oil is applied to the surface of the threads before they are wound.

[0003] An oil tank is needed to wrap the oil onto the silk thread. An oil wheel is set in the oil tank. The oil wheel rotates and contacts the oil in the oil tank. Therefore, when the silk thread contacts the oil wheel, the oil is also wrapped onto the silk thread.

[0004] However, when the paper tube is full of silk thread, the silk thread needs to be cut first and then replaced with a new paper tube. During this process, the silk thread is still being transported. In order to prevent the silk thread from being wound into other equipment (such as a texturing machine), a negative pressure tube is set on the silk thread transportation path. The free end of the cut silk thread will be temporarily sucked into the negative pressure tube. However, problems will arise at this time. First, the silk thread is wrapped with a layer of oil, and the surface friction coefficient is low, so the negative pressure tube will not be able to suck in the silk thread. Second, when the negative pressure tube absorbs the silk thread, it will suck in the oil attached to it, causing the oil to block the negative pressure tube. Therefore, a silk thread deoiling device is urgently needed to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a wire de-oiling device, in which the linear drive device can drive the wire device to swing upward, so that the wire conveying path guided by the wire device is raised, and the wire is no longer in contact with the oil wheel in the oil tank, so that the oil no longer adheres to the wire, thereby preventing the negative pressure pipe from being unable to suck the wire due to the wire being wrapped in oil, and also preventing the oil on the wire from being sucked into the negative pressure pipe and causing the negative pressure pipe to be blocked.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A silk thread deoiling device includes a shaft and several groups of wire devices connected to the shaft, at least two groups of fixed seats are rotatably connected to the shaft, and a torsional damping assembly is provided on the shaft to hinder the rotation of the shaft relative to the fixed seat. Several groups of force-bearing devices are also fixed on the shaft, and a linear drive device is also included. The linear drive device is used to drive the shaft to rotate through the force-bearing device, thereby driving the wire device to swing up and down.

[0008] Furthermore, the force-bearing device includes a bearing and a first connecting rod fixedly connected to the shaft body, a connecting shaft is fixed on the first connecting rod, and the connecting shaft is fixedly connected to the rotating circle of the bearing.

[0009] Furthermore, the linear drive device includes a cylinder, and a push plate for contacting the outer ring of the bearing is fixed on the output shaft of the cylinder.

[0010] Furthermore, the torsional damping assembly includes a torsion spring and a limiting rod fixed on the shaft body, one free end of the torsion spring is fixed on the limiting rod, and the other free end is fixed on the fixing seat.

[0011] Furthermore, the guide wire device includes a second connecting rod fixedly connected to the shaft body, and a guide wire wheel is provided on the second connecting rod.

[0012] Furthermore, limiting rings for limiting the thin wire from escaping from the wire pulley are provided on both sides of the wire pulley, and the limiting rings are fixed on the second connecting rod.

[0013] Furthermore, the bottom of the limiting ring body is inclined toward the guide wheel and the inclination angle is 5 degrees to 15 degrees.

[0014] Furthermore, a protective plate is fixedly connected to the fixing seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The linear drive device of the present invention can drive the wire device to swing upward, thereby raising the conveying path of the wire guided by the wire device, and further preventing the wire from contacting the oil wheel in the oil tank, so that the oil no longer adheres to the wire, thereby preventing the negative pressure pipe from being unable to suck the wire in due to the wire wrapping the oil, and also preventing the oil on the wire from being sucked into the negative pressure pipe and causing the negative pressure pipe to be blocked.

[0017] When the push plate of the utility model applies force to the bearing under the action of the cylinder, the shaft drives the wire device to rotate clockwise, and the outer ring of the bearing itself rotates. When the shaft slides on the push plate, the friction between the push plate and the bearing can be reduced.

[0018] The torsional damping assembly of the present invention can remain stable when the shaft is not subjected to external force. When the shaft is subjected to external force, the external force causes the shaft to overcome the force applied by the torsional damping assembly, thereby causing the shaft to rotate. When the external force disappears, the torsional damping assembly can reset the shaft, thereby resetting the wire guide device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 and Figure 5 As shown, a silk thread deoiling device includes a shaft body 1 and several groups of wire devices 3 connected to the shaft body 1. At least two groups of fixed seats 10 are rotatably connected to the shaft body 1. A torsional damping component 4 is provided on the shaft body 1 to hinder the rotation of the shaft body 1 relative to the fixed seat 10. Several groups of force devices 2 are also fixed on the shaft body 1, and a linear drive device is also included. The linear drive device is used to drive the shaft body 1 to rotate through the force device 2, thereby driving the wire device 3 to swing up and down.

[0027] In this embodiment, the linear drive device includes a cylinder 8, and a push plate 9 is fixed on the output shaft of the cylinder 8 to contact the outer ring of the bearing 203. Under normal circumstances, after the silk thread is guided by the wire guide device 3, it will contact the oil tanker 6, and the oil tanker 6 will contact the oil in the oil tank 7. Therefore, as the oil tanker 6 rotates, the oil will wrap around the silk thread to prevent the silk threads from sticking to each other during subsequent winding. When the negative pressure pipe is used to absorb the silk thread, the cylinder 8 will push the push plate 9 horizontally to move, so that the push plate 9 applies force to the force-bearing device 2, so that the shaft body 1 overcomes the resistance applied by the torsional damping component 4 and rotates, thereby driving the wire guide device 3 to rotate upward, so that the conveying path of the silk thread is raised and no longer contacts the oil tanker 6, thereby avoiding the negative pressure pipe from being unable to suck the silk thread due to the silk thread wrapping the oil, and also avoiding the oil on the silk thread being sucked into the negative pressure pipe and causing the negative pressure pipe to be blocked.

[0028] Among them, such as Figure 2As shown, the force-bearing device 2 includes a bearing 203 and a first connecting rod 201 fixedly connected to the shaft body 1. A connecting shaft 202 is fixed on the first connecting rod 201. The connecting shaft 202 is fixedly connected to the rotating circle of the bearing 203. The outer ring of the bearing 203 can rotate relative to the connecting shaft 202. Figure 5 As shown, the angle between the push plate 9 and the first connecting rod 201 is less than 40 degrees. When the push plate 9 moves under the action of the cylinder 8, the push plate 9 will apply force to the bearing 203, so that the bearing 203 drives the first connecting rod 201 to rotate clockwise, and then drives the wire guide device 3 to rotate clockwise through the shaft 1, so that the wire guide device 3 swings upward to ensure that the silk thread no longer contacts the tanker 6. During this process, the outer ring of the bearing 203 will slide on the push plate 9, and the outer ring of the bearing 203 will rotate, thereby reducing the friction between the push plate 9 and the bearing 203.

[0029] Among them, such as Figure 1 As shown, the torsional damping assembly 4 includes a torsion spring 402 and a limiting rod 401 fixed to the shaft body 1. One free end of the torsion spring 402 is fixed to the limiting rod 401 and the other free end is fixed to the fixing seat 10. Therefore, when the shaft body 1 is not subjected to force, it cannot rotate, thereby ensuring the stability of the wire guide device 3. When the shaft body 1 is subjected to force, the torsion spring 402 will deform, thereby changing the position of the wire guide device 3 through the rotation of the shaft body 1, and when the external force on the shaft body 1 disappears, the torsion spring 402 will reset, thereby driving the wire guide device 3 to reset, so as to ensure that the wire is in contact with the tanker 6 again during transportation.

[0030] Among them, such as Figure 1 and Figure 3 As shown, the wire guide device 3 includes a second connecting rod 301 fixedly connected to the shaft body 1, and a wire pulley 302 is provided on the second connecting rod 301. The connection mode of the wire pulley 302 and the second connecting rod 301 can be a fixed connection or a rotational connection. Limiting rings 303 are provided on both sides of the wire pulley 302 to limit the thin wire from escaping from the wire pulley 302. The limiting rings 303 are fixed on the second connecting rod 301. The diameter of the limiting rings 303 is larger than the diameter of the wire pulley 302. The bottom of the limiting ring 303 is inclined toward the wire pulley 302 and the inclination angle is 5 degrees to 15 degrees. Therefore, when the silk thread passes through the bottom of the wire pulley 302, the limiting ring 303 can limit the silk thread, thereby reducing the possibility of the silk thread escaping from the wire pulley 302 when the wire guide device 3 swings up and down.

[0031] like Figure 4 As shown, a protective plate 5 is fixedly connected to the fixing seat 10. When the device is installed, the protective plate 5 is located at the outermost side. If equipment or personnel pass through the workshop, they can be prevented from touching the oil tank 7, silk thread and other mechanisms.

[0032] Working principle: when the silk thread needs to be wound onto the paper drum of the winding machine, the wire device 3 is in the initial position. At this time, the silk thread will contact the oil tanker 6 after being guided by the wire device 3, thereby wrapping the oil onto the silk thread to prevent the silk threads from sticking to each other during subsequent winding. When the negative pressure pipeline is used to absorb the silk thread, the cylinder 8 will push the push plate 9 horizontally to move, so that the push plate 9 applies force to the force-bearing device 2, so that the shaft 1 overcomes the resistance applied by the torsional damping component 4 and rotates, thereby driving the wire device 3 to rotate upward, so that the conveying path of the silk thread is raised and no longer contacts the oil tanker 6, thereby avoiding the negative pressure pipe from being unable to suck in the silk thread due to the silk thread wrapping the oil, and also avoiding the oil on the silk thread being sucked into the negative pressure pipe and causing the negative pressure pipe to be blocked.
