Description

Technical Field

[0001] The utility model relates to the technical field of textile yarns, and more specifically, to an online yarn moistening device. Background Art

[0002] Before the yarn is fed into the corresponding textile equipment, depending on the specific situation, there will generally be a lubrication operation on the yarn to make the hairiness on the yarn lie on the yarn. In this way, in the subsequent weaving process of feeding the textile equipment, friction can be reduced, making it smoother and reducing the hairiness from falling off the yarn. Therefore, a lubrication device is needed.

[0003] For example, the existing related patent CN220132532U is retrieved, which discloses a yarn lubrication device. In the prior art, the yarn is sprayed with lubricating oil and passes between two sponge wheels. The motor drives the transmission shaft to rotate, and the transmission shaft drives the sponge wheel to rotate through the first gear. The sponge wheel absorbs excess lubricating oil on the yarn to prevent the lubricating oil from dripping during yarn transmission and affecting the working environment.

[0004] However, the inventors have discovered that the prior art has the following problems when in use: in the prior art, lubricating oil is sprayed on the yarn by spraying, which results in the lubricating oil only being sprayed on the top surface of the yarn, resulting in inconsistent lubricating effects on the upper and lower surfaces of the yarn; at the same time, the spraying method will also cause the yarn surface to absorb too much lubricating oil, so the prior art sets an extrusion structure; however, when the extrusion structure squeezes too much lubricating oil on the yarn, the yarn will be squeezed and deformed, affecting the subsequent use of the yarn. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an online yarn lubricating device which will not cause the yarn to be coated with too much lubricating oil, so that the yarn does not require an additional extrusion component after lubrication, thereby minimizing the problem of yarn deformation after extrusion and ensuring the subsequent use effect of the yarn.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A yarn online lubricating device comprises a bottom shell and a top cover installed on the bottom shell, wherein the top cover is provided with a storage box for storing lubricating oil internally, and two through holes are provided on the left and right sides of the bottom shell, both of which are connected to the interior of the bottom shell, and the yarn passes through the bottom shell through the two through holes, and two rotating disks arranged vertically and parallel are provided in the bottom shell, and two sponge wheels are sleeved on the outer surfaces of the two rotating disks, and the two sponge wheels are provided with annular grooves with a vertical cross-section of semicircle, and the annular grooves on the two sponge wheels are combined into a circle, and the yarn passes through the annular grooves of the two sponge wheels and contacts the inner walls of the annular grooves, and the bottom wall of the storage box is provided with two L-shaped through grooves, both of which extend out of the lower surface of the top cover, and the horizontal grooves of the L-shaped through grooves are inclined and located directly above the sponge wheels, and a sealing mechanism for opening and closing the L-shaped through grooves is provided in the storage box.

[0008] The utility model is further configured as follows: two rotating shafts are arranged on the lower surfaces of the two rotating disks, the lower ends of the two rotating shafts are rotatably connected to the bottom wall of the bottom shell, and the lower surface of the bottom shell is provided with two servo motors which respectively control the two rotating shafts to rotate in relative directions.

[0009] The utility model is further configured as follows: extrusion plates for extruding sponge wheels are fixedly connected to the inner walls on both sides of the front and rear of the bottom shell.

[0010] The utility model is further configured as follows: the storage box is provided with a feeding pipe communicated with the interior thereof, and the feeding pipe is provided with a sealing cover for alignment and sealing.

[0011] The utility model is further configured as follows: the sealing mechanism includes a plug for sealing the L-shaped through-slot vertical groove, the plug is arranged in the storage box, a push rod is arranged on the lower surface of the plug, the lower end of the push rod slides through the lower surface of the top cover, a trigger ring is arranged on the upper surface of the rotating disk, the trigger ring and the rotating disk are at the same center, a plurality of arc-shaped protrusions arranged in a circular array are provided on the trigger ring, and the lower end of the push rod contacts the upper surface of the trigger ring and the arc surface of the arc-shaped protrusion.

[0012] The utility model is further configured as follows: the plug head is in a truncated cone shape, and its bottom seals the vertical groove of the L-shaped through groove.

[0013] The utility model is further configured as follows: two built-in cavities are opened in the top cover, the lower end of the push rod passes through the built-in cavity, a built-in ring is fixedly sleeved on the outer surface of the push rod located in the built-in cavity, and a spring movably sleeved on the outer surface of the push rod is arranged between the upper surface of the built-in ring and the top wall of the built-in cavity.

[0015] The advantages of the utility model are:

[0016] Firstly, when the utility model drives the sponge wheel to rotate through the rotating disk, the lubricating oil absorbed by the sponge wheel can be wiped on the surface of the yarn. At the same time, since the vertical section of the annular groove of the sponge wheel is a semicircle, the two sponge wheels can be used to coat the yarn with lubricating oil in all directions when rotating. At the same time, the yarn and the sponge wheels are both running, so the yarn will not be coated with too much lubricating oil. In this way, the yarn does not need an additional extrusion component after lubrication, which avoids the problem of deformation of the yarn after extrusion as much as possible, and ensures the use effect of the yarn in the later stage.

[0017] Secondly, the utility model uses a blocking mechanism, so the lubricating oil can be dripped onto the sponge wheel intermittently, and the lubricating oil will not be dripped onto the sponge wheel all the time, causing the sponge wheel to absorb too much lubricating oil and affecting the lubricating effect on the yarn. At the same time, the blocking mechanism has better stability and low fault effect than the existing solenoid valve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] See also Figure 1-5 , the utility model provides the following technical solutions:

[0025] Specifically, it refers to a yarn online lubricating device, including a bottom shell 1 and a top cover 2 installed on the bottom shell 1, the top cover 2 and the bottom shell 1 are connected by bolts, a storage box 3 for storing lubricating oil is arranged on the top cover 2, two through holes 4 are arranged on the left and right sides of the bottom shell 1, both of which are connected to the inside, the yarn passes through the bottom shell 1 through the two through holes 4, two rotating disks 5 arranged vertically and parallel are arranged in the bottom shell 1, the outer surfaces of the two rotating disks 5 are sleeved with two sponge wheels 6, the two sponge wheels 6 are each provided with an annular groove with a semicircular vertical cross-section, the annular grooves on the two sponge wheels 6 are combined into a circle, the yarn passes through the annular grooves of the two sponge wheels 6 and contacts with the inner walls of the annular grooves, the bottom wall of the storage box 3 is provided with two L-shaped through grooves 10 both extending from the lower surface of the top cover 2, and the transverse grooves of the L-shaped through grooves 10 are It is arranged at an angle and is located directly above the sponge wheel 6. A blocking mechanism for opening and closing the L-shaped through groove 10 is provided in the storage box 3. Therefore, when the blocking mechanism does not close the L-shaped through groove 10, the lubricating oil in the storage box 3 can drip onto the sponge wheel 6 through the L-shaped through groove 10. In this way, when the rotating disk 5 drives the sponge wheel 6 to rotate, the lubricating oil absorbed by the sponge wheel 6 can be wiped on the surface of the yarn. At the same time, since the vertical cross-section of the annular groove of the sponge wheel 6 is a semicircle, the two sponge wheels 6 can be used to apply lubricating oil to the yarn in all directions when rotating. At the same time, the yarn and the sponge wheel 6 are both in operation, so the yarn will not be coated with too much lubricating oil. In this way, the yarn does not need an additional extrusion component after lubrication, which avoids the problem of deformation of the yarn after extrusion as much as possible, thereby ensuring the use effect of the yarn in the later stage.

[0026] Two rotating shafts 7 are provided on the lower surfaces of the two rotating disks 5, and the lower ends of the two rotating shafts 7 are rotatably connected to the bottom wall of the bottom shell 1. Two servo motors 8 are provided on the lower surface of the bottom shell 1 for respectively controlling the two rotating shafts 7 to rotate in relative directions. Therefore, by starting the two servo motors 8, the two rotating disks 5 can be synchronously driven to rotate in relative directions.

[0027] Extrusion plates 9 for squeezing the sponge wheel 6 are fixedly connected to the inner walls on both sides of the front and rear of the bottom shell 1. The distance between the extrusion plate 9 and the outer edge of the rotating disk 5 is smaller than the width of the sponge wheel 6. Therefore, after the sponge wheel 6 has coated the lubricating oil on the surface of the yarn, it will move toward the extrusion plate 9 driven by the rotating disk 5, and the sponge wheel 6 will be squeezed by the extrusion plate 9, so that the lubricating oil remaining on the sponge wheel 6 is squeezed out and falls onto the bottom wall of the bottom shell 1. This can avoid the sponge wheel 6 from absorbing too much lubricating oil when used for a long time, thereby affecting the coating effect on the yarn.

[0028] A pump body 302 is provided on the outer surface of the bottom shell 1, and the extraction port of the pump body 302 penetrates into the bottom shell 1. A filter is installed in the extraction port of the pump body 302, and a delivery pipe 303 is provided on the output port of the pump body 302. A flange head connected to the delivery pipe 303 is provided on the outer surface of the storage box 3, and the flange head is connected to the inside of the storage box 3. Therefore, the pump body 302 can extract the lubricating oil that falls on the bottom wall of the bottom shell 1 into the storage box 3, so as to achieve the purpose of recycling. At the same time, the filter can isolate impurities in the lubricating oil, thereby ensuring the cleanliness of the lubricating oil entering the storage box 3.

[0029] The storage box 3 is provided with a feeding pipe 301 communicating with the interior thereof. The feeding pipe 301 is provided with a sealing cover for alignment and sealing, so that the lubricating oil can be added to the storage box 3 through the feeding pipe 301 .

[0030] The sealing mechanism includes a plug 101 for sealing the vertical groove of the L-shaped through groove 10. The plug 101 is arranged in the storage box 3. The plug 101 is in the shape of a truncated cone, and its bottom seals the vertical groove of the L-shaped through groove 10. A push rod 102 is arranged on the lower surface of the plug 101. The lower end of the push rod 102 slides through the lower surface of the top cover 2. A trigger ring 103 is arranged on the upper surface of the rotating disk 5. The trigger ring 103 and the rotating disk 5 are at the same center. The trigger ring 103 is provided with a plurality of arc-shaped protrusions arranged in a circular array. The lower end of the push rod 102 contacts the upper surface of the trigger ring 103 and the arc surface of the arc-shaped protrusions. When the rotating disk 5 rotates, the trigger ring 103 rotates synchronously with the rotating disk 5. When the lower end of the push rod 102 contacts the arc-shaped protrusions, the trigger ring 103 rotates synchronously with the rotating disk 5. When the arc surface of the protrusion contacts, the arc-shaped protrusion will form a thrust on the push rod 102, so that the push rod 102 pushes the plug 101 to move upward, so that the plug 101 no longer seals the L-shaped through groove 10, so that the lubricating oil in the storage box 3 drips along the L-shaped through groove 10 onto the sponge wheel 6, and when the push rod 102 no longer contacts with the arc-shaped protrusion, the plug 101 seals the L-shaped through groove 10 again under its own gravity and the gravity of the push rod 102. The above-mentioned sealing mechanism can intermittently drip lubricating oil to the sponge wheel 6, and the lubricating oil will not drip to the sponge wheel 6 all the time, causing the sponge wheel 6 to inhale too much lubricating oil, affecting the lubricating effect on the yarn. At the same time, the sealing mechanism and the existing solenoid valve have better stability and low fault effect.

[0031] There are two built-in cavities 104 in the top cover 2, and the lower end of the push rod 102 passes through the built-in cavity 104. The outer surface of the push rod 102 located in the built-in cavity 104 is fixedly sleeved with a built-in ring 105, and a spring 106 movably sleeved on the outer surface of the push rod 102 is arranged between the upper surface of the built-in ring 105 and the top wall of the built-in cavity 104. Since the servo motor 8 does not have a self-locking effect after power failure, the spring 106 loses its restriction after the servo motor 8 stops running, so that the spring 106 will push the built-in ring 105 to move to the built-in cavity 1 04 is at the lowest point, and the push rod 102 moves downward synchronously. If the lower end of the push rod 102 contacts the arc surface of the trigger ring 103 when the servo motor 8 stops running, the downward movement of the push rod 102 will generate a thrust on the trigger ring 103, and the trigger ring 103 rotates until the lower end of the push rod 102 contacts the plane of the trigger ring 103, and the plug 101 seals the L-shaped through groove 10 again, so as to avoid the problem that the plug 101 is in an open state after the servo motor 8 stops running, causing the lubricating oil in the storage box 3 to keep flowing downward.

[0032] The working principle of the yarn online lubricating device provided by the utility model is as follows: by starting two servo motors 8, the two rotating disks 5 can be synchronously driven to rotate in relative directions. When the rotating disk 5 drives the sponge wheel 6 to rotate, the lubricating oil absorbed by the sponge wheel 6 can be wiped on the surface of the yarn. At the same time, when the rotating disk 5 rotates, the trigger ring 103 rotates synchronously with the rotating disk 5. When the lower end of the push rod 102 contacts the arc surface of the arc-shaped protrusion, the arc-shaped protrusion will form a thrust on the push rod 102, so that the push rod 102 pushes the plug 101 to move upward, so that the plug 101 no longer seals the L-shaped through groove 10, so that the lubricating oil in the storage box 3 drips onto the sponge wheel 6 along the L-shaped through groove 10, and when the push rod 102 no longer contacts the arc-shaped protrusion, the plug 101 seals the L-shaped through groove 10 again under its own gravity and the gravity of the push rod 102.
