Description

Technical Field

[0001] This invention relates to the field of conveyor roller technology, and in particular to a conveyor roller device for yarn tube paper production that can prevent paper breakage. Background Technology

[0002] Yarn tube paper is a special type of paper mainly used in the manufacture of yarn tubes in textile machinery. Yarn tubes are crucial components used to wind yarn during the textile process, and yarn tube paper serves as the base material for the yarn tube, possessing high strength, high toughness, and good processing performance. Occasionally, yarn tube paper may break during production when conveyed by transport rollers. The reasons for this are mainly twofold: firstly, the production line's tensioning structure may fail, causing a sudden increase in overall tension with nowhere to release, resulting in yarn tube paper breakage; secondly, uneven stress on both sides of the yarn tube paper may occur due to various reasons, such as foreign objects on the surface of the transport rollers, which could cause a sudden increase in stress on one side. This sudden increase in tension on that side causes the yarn tube paper to tear from that side, eventually leading to overall breakage.

[0003] Chinese Patent CN218859965U discloses a conveyor roller device for yarn tube paper production that prevents paper breakage. The device includes two conveyor rollers with a housing between them. An abutment mechanism is located on the upper side of the housing's inner cavity. The abutment mechanism includes a first mounting frame positioned on the upper side of the housing's inner cavity. An abutment roller is rotatably mounted between the bottom ends of the first mounting frame. A transmission assembly, a drive mechanism, and a limiting member are located on the bottom side of the housing. The transmission assembly and drive mechanism are connected. A fixing plate is located between the limiting member and the top of the transmission assembly. A pressure sensor is located on the upper side of the fixing plate, and a support mechanism is located at the top of the pressure sensor. This design can detect paper tension and adjust it when the tension is high, thereby preventing paper breakage.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: adjusting the height of the support roller to adjust the tension of the yarn tube paper conveying is equivalent to a tension adjustment structure. It is effective in adjusting the overall tension of the yarn tube paper, but it is difficult to deal with the problem of yarn tube paper breaking due to uneven tension on both sides of the yarn tube paper. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art where uneven tension on both sides of the yarn tube paper is difficult to adjust, leading to yarn tube paper breakage. This invention proposes a conveyor roller device for yarn tube paper production that can prevent paper breakage.

[0006] The technical solution of the present invention: a conveying roller device for yarn tube paper production that can prevent paper breakage, used to convey yarn tube paper; comprising: a lifting frame; guide rollers c, arranged on the lifting frame along the width direction of the yarn tube paper, two guide rollers c are coaxially arranged, the two guide rollers c can rotate up and down with the side near the middle position of the yarn tube paper as the rotation center, thereby releasing the increased tension on both sides of the yarn tube paper, the bottom of the yarn tube paper is pressed on the two guide rollers c for guidance and conveying; and an adjustment mechanism, arranged on the lifting frame, used to adjust the rotation and reset of the guide rollers c.

[0007] Preferably, it also includes two sets of guiding mechanisms, which are located on both sides of the lifting frame. One set of guiding mechanisms includes a roller frame and a guide roller a rotatably mounted thereon. The other set of guiding mechanisms includes a roller frame and a guide roller b rotatably mounted thereon. The guide roller c is higher than the guide roller a and the guide roller b. The yarn tube paper passes under the guide roller a, above the guide roller c, and below the guide roller b in sequence.

[0008] Preferably, it also includes a lifting adjustment mechanism, which is set between the two sets of guide mechanisms. The lifting adjustment mechanism is used to adjust the up and down movement of the lifting frame, and releases the overall tension of the yarn tube paper by moving the lifting frame downward.

[0009] Preferably, the lifting adjustment mechanism includes a base, a damper disposed on the base and connected to the bottom of the lifting frame, and a spring that connects the lifting frame and the base.

[0010] Preferably, two rotating shafts are rotatably arranged on the lifting frame, the rotating shafts are arranged along the yarn tube paper conveying direction, the two rotating shafts are located directly below the middle position of the yarn tube paper, the rotating shafts are provided with connecting rods, the top of the connecting rods are horizontally provided with support rods, and the guide roller c is rotatably sleeved on the support rods.

[0011] Preferably, a torsion spring is fitted on the rotating shaft, with both ends of the torsion spring connected to the connecting rod and the lifting frame, respectively. The torsion spring is used to cause the guide roller c to flip upward and reset.

[0012] Preferably, the lifting frame is provided with threaded holes, and nuts are fitted inside the threaded holes. The two ends of the rotating shaft pass through the nuts and are rotatably connected to the bottom of the threaded holes. The end of the torsion spring is connected to the nut.

[0016] Example 1; as Figure 1 and Figure 3 As shown, the present invention proposes a conveying roller device for yarn tube paper production that can prevent paper breakage, used to convey yarn tube paper 1; including: a lifting frame 7; guide rollers c15, which are arranged on the lifting frame 7 along the width direction of the yarn tube paper 1, two guide rollers c15 are coaxially arranged, the two guide rollers c15 can rotate up and down with the side near the middle position of the yarn tube paper 1 as the rotation center, thereby releasing the tension that increases on both sides of the yarn tube paper 1. The bottom of the yarn tube paper 1 is pressed on the two guide rollers c15 for guidance and conveying. When the tension on one side of the yarn tube paper 1 is too large, the corresponding guide roller c15 will be pressed down to make it rotate downward, thereby reducing the tension on that side of the yarn tube paper 1, thereby balancing the tension on both sides of the yarn tube paper 1 and preventing the yarn tube paper 1 from breaking due to excessive tension on one side; and an adjustment mechanism, which is arranged on the lifting frame 7, used to adjust the rotation and reset of the guide rollers c15. It also includes two sets of guiding mechanisms, which are located on both sides of the lifting frame 7. One set of guiding mechanisms includes a roller frame 2 and a guide roller a3 rotatably mounted on it. The other set of guiding mechanisms includes a roller frame 2 and a guide roller b5 rotatably mounted on it. The guide roller c15 is higher than the guide rollers a3 and b5. The yarn tube 1 passes under the guide roller a3, above the guide roller c15, and below the guide roller b5 in sequence. Specifically, the guide rollers a3 and b5 are both arranged along the width direction of the yarn tube 1. The guide rollers a3 and b5 are both connected to the roller frame 2 through the mounting frame 4. The central axis of the guide rollers a3 and b5 and the mounting frame 4 are rotatably connected by bearings. The mounting frame 4 and the roller frame 2 are connected by multiple bolts. After being guided by the guide rollers a3, c15, and b5, the yarn tube 1 forms an upward convex trend at the guide roller c15.

[0017] Example 2; as Figure 2 and Figure 3As shown, the present invention proposes a conveying roller device for yarn tube paper production that can prevent paper breakage. Compared with Embodiment 1, this embodiment details the lifting adjustment mechanism. The lifting adjustment mechanism is set between two sets of guide mechanisms and is used to adjust the up and down movement of the lifting frame 7. The downward movement of the lifting frame 7 releases the overall tension of the yarn tube paper 1.

[0018] The lifting adjustment mechanism includes a base 6, a damper 10 mounted on the base 6 and connected to the bottom of the lifting frame 7, and a spring 9 that connects the lifting frame 7 and the base 6. In an optional embodiment, the spring 9 is sleeved on the damper 10. When the yarn tube paper 1 is subjected to abnormal tension, causing a surge in tension, the entire lifting frame 7 will be forced to move downward to relieve the abnormal tension, thereby preventing the yarn tube paper 1 from breaking. In order to improve the stability of lifting, multiple vertical guide rods 8 are also provided at the bottom of the lifting frame 7, and multiple guide holes for the guide rods 8 to be inserted are provided on the base 6.

[0019] Two rotating shafts 11 are rotatably mounted on the lifting frame 7. The rotating shafts 11 are arranged along the conveying direction of the yarn tube paper 1. The two rotating shafts 11 are located directly below the middle position of the yarn tube paper 1. A connecting rod 13 is provided on the rotating shaft 11. A support rod 14 is horizontally mounted on the top of the connecting rod 13. The guide roller c15 is rotatably sleeved on the support rod 14. In an optional embodiment, the top of the connecting rod 13 and the support rod 14 are connected by a bent tube. The side edge of the yarn tube paper 1 is located at three-quarters of the way out from the guide roller c15. This ensures the normal conveying of the yarn tube paper 1 and also ensures that the tension of the yarn tube paper 1 edge is released when the guide roller c15 flips downward. A torsion spring 12 is fitted on the rotating shaft 11. The two ends of the torsion spring 12 are connected to the connecting rod 13 and the lifting frame 7, respectively. The torsion spring 12 is used to flip the guide roller c15 upward and reset it. In this embodiment, two torsion springs 12 are provided on each rotating shaft 11. The two torsion springs 12 are symmetrical about the connecting rod 13. It should be noted that before use, the state of the two guide rollers c15 needs to be observed. In the no-load state, the two guide rollers c15 need to be flipped upward to form a 15-degree angle with the horizontal plane. In the conveying state, the two guide rollers c15 are in a horizontal state. If the angle requirements in the no-load and conveying states cannot be met, the state of the torsion spring 12 needs to be adjusted or the torsion spring 12 needs to be replaced.

[0020] Example 3; as Figure 3As shown, this invention proposes a conveyor roller device for yarn tube paper production that can prevent paper breakage. Compared with Embodiment 2, this embodiment details the adjustment structure of the torsion spring 12, specifically as follows: A threaded hole is provided on the lifting frame 7, and a nut is fitted inside the threaded hole. Both ends of the rotating shaft 11 pass through the nut and are rotatably connected to the bottom of the threaded hole. The end of the torsion spring 12 is connected to the nut. When the angle of the guide roller c15 is not up to standard under no-load and conveying conditions, the torsion state of the torsion spring 12 can be changed by rotating the nut, making adjustment simpler and more convenient. The distance between the torsion springs 12 on the two rotating shafts 11 is greater than five millimeters but not more than ten millimeters, leaving a certain space to prevent interference between the torsion springs 12. Controlling the maximum distance between the torsion springs 12 is to reduce the distance between the two guide rollers c15 and reduce the unsupported length in the middle of the yarn tube paper 1.

[0021] In summary, during use, the yarn tube 1 is guided by guide rollers a3 and b5 and pressed against guide roller c15 to form an upwardly convex conveying structure. When the overall tension of the yarn tube 1 is too high, it will drive the lifting frame 7 to move downward to release the tension, thereby preventing the yarn tube 1 from breaking. When the tension returns to normal, the lifting frame 7 will slowly return to its original position under the action of spring 9 and damper 10. When the tension on one side of the yarn tube 1 in the width direction increases abnormally, the guide roller c15 on the corresponding side will be pressed down to lower that side of the yarn tube 1, thereby relieving the increased tension and preventing the side of the yarn tube 1 from tearing and ultimately breaking. When the tension returns to normal, the guide roller c15 will return to its original position under the action of torsion spring 12.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
