Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and more specifically, it relates to an anti-spinning device for twisting machines. Background Technology

[0002] In the production process of a twisting machine, the stable feeding of the yarn is a key link to ensure the quality of the final product and production efficiency. As an important piece of equipment that twists multiple yarns into strands, the feeding state of the yarn during operation directly affects the uniformity and compactness of the twist, as well as the overall performance of the product.

[0003] Currently, in the initial feeding process of yarn using twisting machines on the market, the distance between the various feeding components is usually fixed, making it difficult to flexibly adjust according to the actual condition of the yarn and to effectively limit its movement. When the yarn deviates slightly due to its own characteristics or external factors, the lack of sufficient restraint will gradually aggravate the deviation, eventually causing the yarn to jump off the normal feeding track, i.e., the yarn skipping phenomenon.

[0004] On the other hand, the thickness of the wires to be processed varies, and this unevenness causes the friction, tension and other forces acting on the wires to be unevenly distributed during the conveying process, which creates a hidden danger for the occurrence of wire skipping.

[0005] Therefore, developing a device that can effectively prevent yarn from skipping during the twisting machine's conveying process is of great practical significance. Utility Model Content

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figure 1-6 The present invention provides the following technical solution:

[0032] Example 1 addresses the problem in the prior art: the thickness of the production line to be processed varies, and it is difficult to limit the production line by adjusting the spacing between the components during the subsequent conveying process, which leads to the production line skipping during the early conveying stage.

[0033] The device includes a frame 1, a twisting device 2 mounted on top of the frame 1, and a rotating roller 3 located beside the twisting device 2. The twisting device 2 also includes an anti-slip device, a contact limiting mechanism 4, an adjusting mechanism 5, and a wire feeding mechanism 6. The contact limiting mechanism 4 is located beside the twisting device 2 and includes a first limiting part 41, a mounting part 42, and an adjusting contact part 43. The first limiting part 41 is rotatably mounted above the housing and is used to receive the wire to be processed. A pair of mounting parts 42 are respectively located on both sides of the first limiting part 41, and both mounting parts 42 are L-shaped. The adjusting contact part 43 is rotatably mounted between the pair of mounting parts 42, and when the adjusting contact part 43 rotates, it can bring the wire to be processed into contact with the first limiting part 41. The adjusting mechanism 5 is located on top of the housing. The wire feeding mechanism 6 is located beside the housing.

[0034] When the production line passes through the first limiting part 41, the first limiting part 41 can abut and restrict the outer side of the production line to ensure stable transport. To prevent the production line from leaving the outer range of the first limiting part 41 during transport, the position of the adjusting abutment part 43 needs to be rotated and adjusted until the adjusting abutment part 43 is above the first limiting part 41 and abuts against the top of the first limiting part 41, at which point the movement stops. Thus, the production line will always be constrained between the first limiting part 41 and the adjusting abutment part 43, effectively preventing it from leaving the outer side of the first limiting part 41 during transport.

[0035] See Figure 5 and Figure 6 The first limiting part 41 has a cylindrical structure, and a circular limiting slot is provided in the middle of the first limiting part 41 to limit the deviation of the filament to be processed.

[0036] Specifically, when the position of the adjusting abutment part 43 is not adjusted, the production line to be processed can be restricted by both sides of the circular limiting groove opened on the end face of the first limiting part 41 in this state, which can ensure the initial stability of the conveying when the production line to be processed is conveyed.

[0037] See Figure 5 and Figure 6 The contact limiting mechanism 4 also includes a rotary cylinder 44 and a rotating part 45; the rotary cylinder 44 has a pair and is respectively disposed on the side of a pair of mounting parts 42; the rotating part 45 has a pair and is respectively disposed on the output end of the rotary cylinder 44, and the two ends of the adjusting contact part 43 are respectively rotatably connected to the end faces of the pair of rotating parts 45.

[0038] Specifically, in order to position the adjusting abutment 43 above the first limiting part 41, a pair of rotary cylinders 44 are first activated. When the pair of rotary cylinders 44 are activated, they can drive the rotating part 45 to rotate. When the rotating part 45 rotates, it can drive the rotatably connected adjusting abutment 43 to rotate synchronously, thereby adjusting the position of the adjusting abutment 43.

[0039] See Figure 2 and Figure 3 The adjustment mechanism 5 also includes a first linear guide rail 51 and a sliding part 52; the first linear guide rail 51 is slidably disposed on the top of the housing and is located beside the rotating roller 3; the sliding part 52 is slidably disposed on the top of the first linear guide rail 51 and the top of the sliding part 52 is connected to the first limiting part 41, and the first limiting part 41 can be rotated on the top of the sliding part 52.

[0040] Specifically, to address the problem of the production line swaying due to decreased tension during transport, this embodiment provides a rotary motor on the side of the first linear guide rail 51 to drive the sliding part 52 to move. The rotary motor is preferably a servo motor. When the rotary motor is started, it drives the sliding part 52 to move at the top of the first linear guide rail 51, thereby solving the swaying problem caused by decreased tension in the production line.

[0041] See Figures 2-4 The adjusting mechanism 5 also includes a connecting part 53 and a hydraulic cylinder 54; the connecting part 53 is slidably disposed on the top of the housing, and the top of the housing is provided with a slot for limiting the sliding of the connecting part 53, and the top of the connecting part 53 is fixedly connected to the first linear guide rail 51. When the connecting part 53 moves, it can drive the first linear guide rail 51 and the sliding part 52 to move synchronously; the hydraulic cylinder 54 is disposed at the bottom of the housing, and the output end of the hydraulic cylinder 54 is fixedly connected to the end face of the connecting part 53.

[0042] Specifically, in order to adjust the position of the first linear guide rail 51, the hydraulic cylinder 54 is first activated. When the hydraulic cylinder 54 is activated, it can drive the connecting part 53 to move in an upward or downward state, thereby enabling the adjustment of the positions of the first linear guide rail 51, the sliding part 52, the first limiting part 41, and the adjusting abutment part 43 to deal with the swaying problem of the line.

[0043] See Figures 2-4 The wire feeding mechanism 6 includes a setting plate 61, a first rotating roller 62, and a bonding roller 63; the setting plate 61 has a pair and is respectively installed on the top of the machine housing; the first rotating roller 62 has a pair and is respectively rotatably disposed between the pair of setting plates 61; the bonding roller 63 has a plurality of rollers and is respectively rotatably disposed on the top of the machine housing, and a gap is left between the plurality of bonding rollers 63 for the wire to be processed to pass through.

[0044] Specifically, in this embodiment, the production line to be processed first passes between the first rotating part 45 and multiple bonding rollers 63. Initially, the production line to be processed is located on top of the first rotating roller 62, and then it is conveyed through the gaps between the multiple bonding rollers 63 in sequence until the production line to be processed passes through the first limiting part 41 and the position of the adjusting abutment part 43, thus completing the conveying of the production line to be processed.

[0045] See Figures 2-4The wire feeding mechanism 6 also includes telescopic cylinders 64 and adjusting rollers 65; there are multiple telescopic cylinders 64 and they are respectively installed on the top of the setting plate 61; there are a pair of adjusting rollers 65 and they are respectively slidably installed on the side of the setting plate 61, and both of the adjusting rollers 65 are located below the first rotating roller 62, and there is a space between the adjusting rollers 65 and the first rotating roller 62 for the wire to be processed to pass through; there are multiple telescopic cylinders 64 and they are respectively installed on the top of the setting plate 61, and the output ends of the multiple telescopic cylinders 64 are rotatably connected to the adjusting rollers 65, so that when the telescopic cylinders 64 are activated, they can drive the adjusting rollers 65 to move in a direction close to the first rotating roller 62.

[0046] Specifically, to address the issue of difficulty in adjusting the position of the adjusting rollers 65 when the production line is thick, the telescopic cylinder 64 is activated. When activated, the telescopic cylinder 64 drives the adjusting rollers 65 to descend until they come into contact with the outer side of the production line to be processed, at which point the movement stops. This positions the production line between the first rotating roller 62 and the adjusting rollers 65, ensuring stable conveying of the production line.

[0047] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
