[0001] The present application relates to the technical field of textile machinery, in particular to a scraper structure, a scraper device, a thread scraping device and a yarn feeding robot. BACKGROUND

[0002] In the existing winding process, a winding machine usually needs to be equipped with 3-5 yarn inserting workers to complete daily production. The yarn inserting workers repeat the mechanical action of picking up the tube yarn, extracting the thread end and putting it into the yarn library every day, which has the problem of low efficiency. Therefore, in order to improve the production efficiency, an automatic winding workshop appears.

[0003] In the process of extracting the thread end, the thread end on the surface of the tube yarn usually needs to be found out and broken by the scraper device to facilitate the next thread suction device to suck out the thread end. However, the existing scraper device cannot find out the thread end and break it in a short time. SUMMARY

[0004] Therefore, it is necessary to provide a scraper structure, a scraper device, a thread scraping device and a yarn feeding robot which can quickly find out the thread end and break it, and can solve the problem that the existing scraper device cannot find out the thread end and break it in a short time.

Therefore, the scraper structure of the present application can find the thread end of the tube yarn and break it in a short time. In addition, by arranging the elastic member, the scraper can adapt to different diameters of the tube yarn, and can tightly contact the surface of the tube yarn for any size of the tube yarn, thereby ensuring that the scraper can find the thread end of the tube yarn and break it.

[0049] Figure 1 A perspective structural schematic diagram of a scraper device according to an embodiment of this application is shown. For ease of description, the accompanying drawings only show structures related to the embodiments of this application.

[0050] Referring to the accompanying drawings, one embodiment of this application provides a scraper structure 100, including a first mounting base 10 and a scraper 20. The scraper device 100 of this application is applied to a scraper device 300, specifically to a yarn feeding robot. In other embodiments, it can also be applied to other devices that utilize the scraper structure 100, and no limitation is made here.

[0051] like Figures 2-4 As shown, the scraper 20 is mounted on the first mounting base 10. The scraper 20 is used to scrape the yarn surface of the tube 200. The scraper 20 has a blade 21 with a first blade line 211 facing the tube 200. The tip 212 of the blade 21 is on the first blade line 211.

[0052] It should be noted that the tip 212 is usually formed by the convergence of at least three blade lines arranged at an angle. The first blade line referred to in this application is the blade line of the blade 21 that is closest to the bobbin 200 in the first direction of the movement of the scraper 20 relative to the bobbin 200.

[0053] The first cutting edge line 211 of this application has an angle with the first axis AA, the second axis BB and the third axis CC. The first axis AA is parallel to the axis of the yarn tube 200, and the first axis AA, the second axis BB and the third axis CC are perpendicular to each other.

[0054] Thus, by setting the first cutting edge line 211 to have angles with the first axis AA, the second axis BB, and the third axis CC, the scraper 20, when approaching the yarn tube 200, first contacts the surface of the yarn tube 200 only through the tip 212 of the cutting edge 21, and then can quickly insert into the outermost layer of yarn in the yarn tube 200, so that the first cutting edge line 211 can quickly and accurately cut off the outermost thread end. Therefore, the scraper structure 100 of this application can find and cut off the thread end of the yarn tube 200 in a short time.

[0055] In a specific embodiment of this application, the first mounting base 10 has a first mounting surface 11, which faces the yarn tube 200, and one end of the scraper 20 is connected to the first mounting surface 11. Specifically, the scraper 20 can be connected to the first mounting surface 11 by welding, or it can be connected to the first mounting surface 11 by threading or other means, which is not limited here.

[0056] Please refer to it again. Figure 2 In some embodiments, the doctor blade 20 is movable along a first direction to move closer to or further away from the yarn tube 200, the first direction being parallel to the second axis BB. More specifically, the first direction is... Figure 2 The left and right directions are shown. Thus, by setting the first direction parallel to the second axis BB, the first direction can be perpendicular to the first axis AA, ensuring that the tip 212 of the scraper 20 can be inserted into the outermost yarn of the tube 200 in the direction intersecting with the virtual cylindrical surface formed by the outermost yarn of the tube 200, thereby enabling the first blade line 211 to cut off the outermost yarn end.

[0057] Please refer to it again. Figure 3 In some embodiments, the scraper 20 further includes a first handle portion 22, one end of which is connected to the first mounting base 10, and the other end of which is connected to the blade 21. Further, the first handle portion 22 protrudes from the first mounting base 10 along a second direction, wherein the second direction is parallel to the third axis CC. Specifically, the second direction is... Figure 3 The left and right directions are shown. In this way, the positional interference of the first mounting part 10 on the contact between the scraper 20 and the yarn tube 200 in the second direction can be avoided.

[0058] Please refer to it again. Figure 4Further, the scraper 20 also has a second shank portion 23, one end of the second shank portion 23 is connected with the first mounting base 10, and the other end of the second shank portion 23 is connected with one end of the first shank portion 22 away from the blade edge 21, wherein the first shank portion 22 and the second shank portion 23 are arranged at an angle. In the embodiment of the present application, the second shank portion 23 extends in the first direction. By arranging the second shank portion 23, the blade edge 21 of the scraper 20 can be further away from the first mounting base 10 in the first direction, so as to avoid the first mounting base 10 interfering with the contact between the scraper 20 and the tube yarn 200 in the first direction.

[0059] Please refer back to Figure 2 In some embodiments, the included angle between the first blade edge line 211 and the first axis AA ranges from 4 degrees to 7.5 degrees. In order to make the description clear, the extension line of the first blade edge line 211 is schematically shown in the drawings. Figure 2 In this way, the tip 212 of the blade edge 21 can be arranged towards the tube yarn 2, so that it can be accurately inserted into the outermost yarn of the tube yarn 200 in a point-like manner. In addition, the first blade edge line 211 in this range can also form a certain angle with the outermost yarn of the tube yarn 200 after the tip 212 is inserted into the outermost yarn of the tube yarn 200, which is beneficial to quickly breaking the yarn.

[0060] Preferably, the included angle between the first blade edge line 211 and the first axis AA is one of 4 degrees, 4.5 degrees, 5 degrees, 5.5 degrees, 6 degrees, 6.5 degrees, 7 degrees, and 7.5 degrees.

[0061] Please refer back to Figure 3 In some embodiments, the included angle between the first blade edge line 211 and one of the second axis BB and the third axis CC is consistent with the winding angle of the tube yarn 200. In the embodiment of the present application, the included angle between the first blade edge line 211 and the second axis BB is consistent with the winding angle of the tube yarn 200.

[0062] It should be noted that the winding angle of the tube yarn 200 of the present application refers to the included angle between the yarn and the central axis of the tube yarn 200.

[0063] Preferably, the winding angle of the tube yarn 200 is one of 15 degrees, 25 degrees, 30 degrees, 40 degrees, 50 degrees, and 60 degrees. In the embodiment of the present application, the winding angle of the tube yarn 200 is 25 degrees.

[0064] Further, the included angle between the first blade edge line 211 and the other one of the second axis BB and the third axis CC ranges from 85.5 degrees to 88.5 degrees. In order to make the description clear, the extension line of the first blade edge line 211 is schematically shown in the drawings. Figure 4An extension line of the first blade line 211 is schematically shown in a dashed line. In the embodiment of the present application, the angle between the first blade line 211 and the third axis CC ranges from 85.5 degrees to 88.5 degrees.

[0065] Preferably, the angle between the first blade line 211 and the third axis CC is one of 85.5 degrees, 86 degrees, 86.5 degrees, 87 degrees, 87.5 degrees, 88 degrees, and 88.5 degrees.

[0066] Please refer to Figure 1 , based on the same inventive concept, the present application further provides a scraper device 300, comprising a second mounting seat 310, the scraper structure 30 described above, and an elastic member 320.

[0067] The second mounting seat 310 is arranged opposite to the first mounting seat 10, and the first mounting seat 10 is movable relative to the second mounting seat 310. The elastic member 320 is pre-pressed between the first mounting seat 10 and the second mounting seat 310, and the elastic member 320 is capable of providing a force for keeping the tip 212 of the blade 21 in contact with the surface of the tube yarn 200 after the tip 212 of the blade 21 contacts the surface of the tube yarn 200. By arranging the elastic member 320, the scraper 20 can adapt to different diameters of the tube yarn 200, and can achieve close contact with the surface of the tube yarn 200 for any size of the tube yarn 200, thereby ensuring that the scraper 20 can find the thread end of the tube yarn 200 and break it.

[0068] Specifically, the elastic member 320 can provide a force for keeping the tip 212 of the scraper 30 in contact with the surface of the tube yarn 200 in the first direction.

[0069] As shown in Figure 5 , further, the scraper device 300 further comprises a guide member 330, one end of the guide member 330 is slidingly connected with one of the first mounting seat 10 and the second mounting seat 310, and the other end is fixedly connected with the other one of the first mounting seat 10 and the second mounting seat 310, and the guide member 330 is used for guiding the first mounting seat 10 to move relative to the second mounting seat 310 to approach or move away from the tube yarn 200. By arranging the guide member 330, the first mounting seat 10 can be guided to approach or move away from the tube yarn 200 in the first direction to adapt to the diameter of the tube yarn 200.

[0070] Further, the elastic member 320 is sleeved with the guide member 330. In this way, the elastic member 320 can be used as a positioning member, so that the elastic member 320 can stably provide the first mounting base 10 with an action force for keeping the tip 212 of the blade 21 in contact with the surface of the tube yarn 200. In addition, the structure of the scraper device 100 can be simplified, and the structure of the scraper device 100 can be more compact.

In other embodiments, the elastic member 320 is also nested in the inner side of the guide member 330, which is not limited here.

[0071] Please refer again to Figure 1 In some embodiments, the scraper device 300 further comprises a first driving member 340 connected with the second mounting base 310, and used for providing the second mounting base 310 with a driving force for moving the scraper 20 in the first direction. In this way, the scraper 20 can be driven by the first driving member 340 to move close to or away from the tube yarn 200. Specifically, the first driving member 340 comprises a first driving cylinder.

[0072] In some embodiments, the scraper device 300 further comprises a second driving member 350 connected with the second mounting base 310, and used for providing the second mounting base 310 with a driving force for moving the scraper 20 in a third direction, wherein the third direction is parallel to the first axis AA. In this way, after the tip 212 of the scraper 20 is inserted into the outermost yarn of the tube yarn 200, the scraper 20 can be driven to move in the third direction, so that the first blade line 211 of the scraper 20 can break the yarn. Specifically, the second driving member 340 drives the scraper 20 to move vertically downward to break the yarn. The second driving member 240 comprises a second driving cylinder.

[0073] In some embodiments, the scraper device 300 comprises a plurality of scraper structures 100 and a plurality of elastic members 320, the plurality of scraper structures 100 are arranged at intervals, and each elastic member 320 is pre-pressed between the first mounting base 10 and the second mounting base 310 of a corresponding scraper structure 100. In this way, the plurality of scraper structures 100 can be installed on the same second mounting base 310, so that the structure of the scraper device 100 can be more compact.

[0074] Specifically, the scraper device 300 further comprises a base 360, the first driving member 340 and the second driving member 350 are both mounted on the base 360, and the second mounting base 310 is mounted on the base 360. In order to reliably move the second mounting base 310 in the first direction and the second direction, the base 360 is provided with a first guide member, and the second mounting base 310 is provided with a first matching part matched with the first guide member to guide the second mounting base 310 to move in the first direction. The base 360 is provided with a second guide member, and the second mounting base 310 is provided with a second matching part matched with the second guide member to guide the second mounting base 310 to move in the third direction. More specifically, the first guide member and the second guide member are both slide rails.

[0075] In order to reduce the weight of the second mounting base 310, so as to reduce the load of the first driving member 340 and the second driving member 450, the second mounting base 310 is provided with a weight-reducing hole 311. In the embodiment of the present application, the weight-reducing hole 311 comprises a plurality of weight-reducing holes, and at least one weight-reducing hole 311 is arranged between two adjacent scraper structures 100.

Figure 6 and Figure 7 Based on the same inventive concept, the present application further provides a thread scraping device 400, which comprises the thread pressing and rotating device 410 and the scraper structure 100 described above.

[0077] The thread pressing and rotating device 410 is used to press and rotate the tube yarn 200 in the third direction parallel to the first axis AA. In this way, after the tip 212 of the scraper 20 is inserted into the outermost yarn of the tube yarn 200, the interaction force between the outermost yarn and the first blade line 211 is provided to enable the first blade line 211 to break the yarn.

[0078] Specifically, the thread pressing and rotating device 410 comprises a third mounting base 411, a moving base 412, a rotating mechanism 413 and a pressing driving member 414.

[0079] The moving base 412 is arranged opposite to the third mounting base 411 in the third direction, the rotating mechanism 413 comprises a rotating member 4131 and a rotating driving member 4132, the rotating member 4131 is arranged on the moving base 412, the rotating driving member 4132 is connected with the rotating member 4131 and is used to provide a driving force for the rotating motion of the rotating member 4131, and the pressing driving member 414 is mounted on the third mounting base 411 and connected with the moving base 412, and is used to provide a driving force for the moving base 412 to move close to or away from the third mounting base 411 in the first direction, so as to press or release the tube yarn 200. Specifically, the third direction is a vertical direction. In the embodiment of the present application, the tube yarn 200 is located on the side of the moving base 412 away from the third mounting base 411 in the third direction.

[0080] It is to be noted that the rotating driving member 4132 has a rotating output end connected with the rotating member 4131 to provide driving force for the rotating movement of the rotating member 4131. Specifically, the rotating driving member 4132 comprises a rotating motor. The pressing driving member 414 has a pressing output end connected with the moving seat 412 to provide driving force for the moving seat 412 to move towards or away from the third mounting seat 411 along the third direction. It is to be noted that the pressing output end connected with the moving seat 412 can be indirect connection or direct connection, which is not limited here. Specifically, the pressing driving member 414 comprises a pressing cylinder.

[0081] By arranging the moving seat 412 opposite to the third mounting seat 411 along the third direction and enabling the moving seat 412 to move away from the third mounting seat 411 under the driving force of the pressing driving member 414 along the third direction, the moving seat 412 drives the rotating member 4131 to press the tube yarn 200 along the third direction, so that the moving direction of the moving seat 412 is consistent with the direction of the tube yarn 200, thereby stably pressing the tube yarn 200 and stably rotating the tube yarn 200.

[0082] In some embodiments, the side of the rotating member 4131 away from the third mounting seat 411 has a friction surface for frictional contact with the surface of the tube yarn 200. The frictional contact is simple and reliable.

[0084] By arranging the first blade line 211 to have an included angle with the first axis AA, the second axis BB and the third axis CC, the scraper 20 can first contact the surface of the tube yarn 200 with the tip 212 of the blade 21 in a point manner when approaching the tube yarn 200, and then quickly insert into the outermost yarn of the tube yarn 200, so that the first blade line 211 can quickly and accurately break the outermost thread end. Therefore, the scraper structure 100 of the present application can find the thread end of the tube yarn 200 and break it in a short time.

[0085] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0086] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific and detailed manner, but should not be construed as limiting the scope of the patent of the present application. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
