Description

Technical Field

[0001] The utility model relates to the technical field of silk winders, in particular to a yarn-breaking length recording device for silk winders. Background Art

[0002] A silk winding machine is a device used in textile machinery to produce synthetic silk threads. It processes the synthetic silk raw materials, including wire drawing, spinning, and cooling, and finally pulls out the silk threads continuously to form one or more silk threads. When producing the silk threads, the length of the silk threads needs to be measured in real time. Therefore, before performing operations such as winding, the silk threads need to pass through a length-recording device. When winding, the silk threads pass through a length-recording wheel, which drives the length-recording wheel to rotate. The length-recording wheel drives the Hall sensor inside the casing to rotate, and the rotating Hall sensor records the length of the silk threads.

[0003] When the silk thread passes through the surface of the length-measuring wheel, the silk thread must first pass through the guide column, which guides the silk thread so that the silk thread can slide on the length-measuring wheel. When the silk thread passes through the guide column, the silk thread will continue to wear the guide column in the same place. When grooves are worn on the surface of the guide column, the friction force is large when the silk thread slides inside the groove, which will cause damage to the silk thread and reduce the quality of the silk thread product. Therefore, the present application provides a yarn-breaking length-measuring device for a silk winding machine to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a yarn length recording device for a silk winding machine to solve the problem that when grooves are worn on the surface of a guide column, the friction force is large when the silk thread slides inside the grooves, which will cause damage to the silk thread and reduce the quality of the silk thread product.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A yarn length recording device for a silk winding machine comprises a housing and a length recording wheel rotatably connected to the surface of the housing, a Hall sensor is provided inside the housing, and the length recording wheel drives the Hall sensor to rotate so as to measure the length of the silk thread passing through the length recording wheel, and further comprises:

[0007] The upper guide column and the lower guide column both include a servo motor fixed inside the casing, the output shaft of the servo motor passes through the casing and is fixedly connected to baffle 1, a cylinder is fixed on the side of baffle 1 away from the casing, and a baffle 2 is fixed on the side of the cylinder away from the casing, and a plurality of protrusions 1 and 2 are provided on the surface of the cylinder, and the protrusions 1 and 2 are alternately arranged at equal distances, and the surface of the protrusion 1 is provided with a slope 1, and the surface of the protrusion 2 is provided with a slope 2, and the inclination angles of the slope 1 and the slope 2 between adjacent protrusions 1 and 2 are opposite, and a plurality of wear blocks are fixed on the surfaces of the slope 1 and the slope 2.

[0008] Preferably, chamfers are provided on the edges of the long sides of the first and second protrusions.

[0009] Preferably, the edge of the wear block is provided with a chamfer.

[0010] Preferably, the height of the wear block is 1.5 times the diameter of the wire.

[0011] Preferably, the spacing between adjacent wear blocks is greater than the diameter of the wire.

[0012] Preferably, a card slot is opened on the surface of the cylinder, and card blocks are fixed on the surfaces of protrusion one and protrusion two. The inner wall of the card slot is inlaid with a magnetic block. When the card blocks on protrusion one and protrusion two are connected to the inner wall of the card slot, the magnetic block is magnetically attracted to the surface of the card block.

[0013] Preferably, sensor 1 is embedded on the side of baffle 1 close to baffle 2, and sensor 1 corresponds to the downward-slanting end of protrusion 2. Sensor 2 is embedded on the side of baffle 2 close to baffle 1, and sensor 2 corresponds to the downward-slanting end of protrusion 1. Both sensor 1 and sensor 2 are electrically connected to the servo motor.

[0014] Preferably, the central axes of the baffle 1, the cylinder and the baffle 2 coincide with each other.

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

[0016] In the above scheme, by setting a servo motor, bump one, bump two and wear block, the silk thread is placed at the high point of bump one or bump two. When the silk thread passes through, the silk thread will contact the wear block, and the wear block will be worn. Therefore, the silk thread will slide downward along the inclined surface of bump one or bump two. When the wear blocks on a certain bump one or bump are worn out, the silk thread will contact sensor one or sensor two. At this time, the servo motor will drive bump one or bump two to rotate, so that the high point position of the adjacent bump one or bump two will re-contact the silk thread, so that it is repeated continuously. Moreover, since the height of the wear block is relatively small, the silk thread will directly wear the wear block during wear, and will not form gullies, thereby reducing the wear on the silk thread.

[0017] By providing the card slot, card block and magnetic block, when the wear block on the bump one or bump two is worn out, the bump one or bump two can be pulled out upwards and replaced with a new bump one or bump two, thereby realizing the rapid replacement of the bump one or bump two.

[0032] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a yarn length recording device for a silk winding machine, comprising a housing 1 and a length recording wheel 2 rotatably connected to the surface of the housing 1, a mounting frame provided on the surface of the housing 1 for mounting the housing 1, a display screen provided on the top of the housing 1, the display screen being electrically connected to a Hall sensor, the length value recorded by the Hall sensor being displayed on the display screen, a Hall sensor provided inside the housing 1, and the length recording wheel 2 driving the Hall sensor to rotate to measure the length of the silk thread passing through the length recording wheel 2, and further comprising:

[0033] The upper guide column 3 and the lower guide column 4, the upper guide column 3 and the lower guide column 4 both include a servo motor fixed inside the casing 1, the output shaft of the servo motor 5 passes through the casing 1 and is fixedly connected to a baffle 1 6, a cylinder 8 is fixed to the side of the baffle 1 6 away from the casing 1, and a baffle 2 7 is fixed to the side of the cylinder 8 away from the casing 1, and a plurality of protrusions 1 9 and protrusions 2 10 are provided on the surface of the cylinder 8, and the protrusions 1 9 and protrusions 2 10 are alternately arranged at equal intervals, and a slope 1 is provided on the surface of the protrusion 1 9, and a slope 2 is provided on the surface of the protrusion 2 10, and the inclination angles of the slope 1 and the slope 2 between adjacent protrusions 1 9 and protrusions 2 10 are opposite, and a plurality of wear blocks 11 are fixed on the surface of the slope 1 and the slope 2.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the edges of the long sides of the protrusion 1 9 and the protrusion 2 10 are both provided with chamfers to reduce the wear of the edges on the wire and improve the product quality of the wire.

[0035] like Figure 4 and Figure 5As shown, in this embodiment, the edge of the wear block 11 is provided with a chamfer, and the chamfer is used to reduce the wear on the wire.

[0036] like Figure 4-Figure 7 As shown, in this embodiment, the height of the wear block 11 is 1.5 times the diameter of the wire. While the wear block 11 supports the wire, the wire will not leave grooves on the wear block 11, reducing wear on the wire.

[0037] like Figure 4-Figure 7 As shown, in this embodiment, the distance between adjacent wear blocks 11 is greater than the diameter of the wire, so that after the wire wears through one wear block 11, it can smoothly contact the next wear block 11.

[0038] like Figure 6 and Figure 7 As shown, in this embodiment, a card slot 14 is opened on the surface of the cylinder 8, and a card block 15 is fixed on the surface of the protrusion 1 9 and the protrusion 2 10. The inner wall of the card slot 14 is inlaid with a magnetic block 16. When the card blocks 15 on the protrusion 1 9 and the protrusion 2 10 are connected to the inner wall of the card slot 14, the magnetic block 16 is magnetically attracted to the surface of the card block 15. The card block 15 is stuck in the card slot 14 and the suction force of the magnetic block 16 on the card block 15, so that the rapid replacement of the protrusion 1 9 or the protrusion 2 10 can be achieved.

[0039] like Figure 4-Figure 7 As shown, in this embodiment, a sensor 12 is embedded on the side of baffle 1 6 close to baffle 2 7, and the sensor 1 12 corresponds to the downward-slanting end of protrusion 2 10. A sensor 2 13 is embedded on the side of baffle 2 7 close to baffle 1 6, and the sensor 2 13 corresponds to the downward-slanting end of protrusion 1 9. Both sensor 1 12 and sensor 2 13 are electrically connected to the servo motor 5. When the wire contacts sensor 1 12 or sensor 2 13, the servo motor 5 will be triggered to rotate baffle 1 6, cylinder 8 and baffle 2 7.

[0040] like Figure 6 and Figure 7 As shown, in this embodiment, the central axes of baffle 1 6 , cylinder 8 and baffle 2 7 coincide with each other, so that when the servo motor 5 drives baffle 1 6 , cylinder 8 and baffle 2 7 to rotate, the rotation is more stable.

[0041] Working principle: After the silk thread passes through the upper guide column 3, the length-recording wheel 2 and the lower guide column 4 in sequence, the silk thread will drive the length-recording wheel 2 to rotate, and the length-recording wheel 2 will drive the Hall sensor in the housing 1 to rotate, and the Hall sensor will record the length of the silk thread passing through;

[0042] When the wire passes through the upper guide column 3 and the lower guide column 4, the wire will first adhere to the high point of the protrusion 1 9 or the protrusion 2 10. As the wire wears the wear block 11, the wire will move downward along the inclined surface of the protrusion 1 9 or the protrusion 2 10, and the wire passes through the wear blocks 11 in sequence. When the wear block 11 on a single protrusion 1 9 or protrusion 2 10 is worn out, the wire is at the low point of the protrusion 1 9 or the protrusion 2 10.

[0043] When the wire is at the lowest point of bump 1-9, the wire contacts sensor 12 of baffle 1-6, which activates servo motor 5. Servo motor 5 drives baffle 1-6 to rotate, which drives cylinder 8 to rotate, and cylinder 8 drives bump 1-9 and bump 2-10 on the surface to rotate, moving the high point of adjacent bump 2-10 to the wire surface, and starting a new round of guidance.

[0044] When the silk thread is at the low point of the second protrusion 10, the silk thread contacts the second sensor 13 of the second baffle 7, and the second sensor 13 starts the servo motor 5, which drives the first baffle 6 to rotate, and the first baffle 6 drives the cylinder 8 to rotate, and the cylinder 8 drives the first protrusion 9 and the second protrusion 10 on the surface to rotate, moving the high point of the adjacent protrusion 9 to the surface of the silk thread, and starting a new round of guidance;

[0045] Secondly, when the wear block 11 on the bump 1 9 or the bump 2 10 is completely worn out and rotated down, the bump 1 9 or the bump 2 10 can be pulled out, and the card block 15 of the new bump 1 9 or the bump 2 10 can be inserted into the card slot 14, and the card block 15 can be fixed by the magnetic attraction of the magnetic block 16.

[0046] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
