Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a winding machine anti-breakage device. Background Technology

[0002] Polyester-cotton yarn is a blend of polyester and cotton, characterized by high tensile strength and abrasion resistance. The first step before weaving is winding, which processes the yarn into bobbins that meet specific requirements. The main functions of the winding machine include changing the package shape, increasing yarn capacity, removing defects and impurities, improving yarn quality, and reducing yarn breakage.

[0003] Reference to the utility model patent with authorization announcement number CN222225570U, a winding drum frame for a winding machine is disclosed, including a winding machine body. Multiple vertical plates are fixedly connected to the upper side of the winding machine body. A winding device for winding yarn is provided on the upper side of the winding machine body. A moving device for uniformly winding yarn is provided between the multiple vertical plates. The winding device includes a drive motor fixedly installed at one end of one of the vertical plates, a coupling rotatably disposed between the multiple vertical plates, and a first connecting plate fixedly connected to one side of the coupling.

[0004] The winding drum described in the above patent is difficult to assemble and disassemble and is not applicable to drums of different diameters. Furthermore, excessive winding tension can easily cause wire breakage. It is inconvenient to use and has a limited range of applications. To address the shortcomings of the above technology, we propose a winding machine anti-breakage device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a winding machine anti-breakage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding machine anti-breakage device includes a winding machine winding mounting plate, a motor fixedly mounted on the rear side of the winding machine winding mounting plate, and a clamping mechanism provided on the front side of the winding machine winding mounting plate; the clamping mechanism includes an inner cylinder, a plurality of rotating grooves evenly distributed on the side wall of the inner cylinder, a rotating strip plate rotatably mounted on the inner side of the rotating groove, an internal threaded port provided at the outer end of the inner cylinder, a threaded post screwed into the inner side of the internal threaded port, a rotating column rotatably mounted on the inner end of the threaded post, and an arc-shaped guide block fixedly mounted on the side wall of the rotating column, the arc-shaped guide block being slidably engaged with the inner side of the rotating groove.

[0008] Furthermore, a rubber strip is fixedly installed on the outer side of the rotating plate, and horizontal grooves are evenly distributed on the rubber strip.

[0009] By adopting the above technical solution, the horizontal groove enhances the surface roughness of the rubber strip and improves its anti-slip function.

[0010] Furthermore, a winding drum is sleeved on the outer side of the inner cylinder, and the inner wall of the winding drum abuts against the outer side of the rubber strip.

[0011] Furthermore, structural folding plates are fixedly installed on both sides of the winding machine's winding mounting plate, and mounting holes are evenly distributed on the structural folding plates.

[0012] By adopting the above technical solution, the mounting holes evenly distributed on the structural folding plate facilitate the installation of the structural folding plate on the winding machine by screwing.

[0013] Furthermore, an electric telescopic rod is fixedly installed on the rear side of the winding machine mounting plate, and the output end of the electric telescopic rod slides through to the front side of the winding machine mounting plate. An anti-breakage mechanism is fixedly installed on the output end of the electric telescopic rod.

[0014] Furthermore, the anti-breakage mechanism includes a mounting plate, which is fixedly mounted on the output end of the electric telescopic rod. An embedded circular groove is provided on the inner side of the mounting plate, and a slider is slidably engaged inside the embedded circular groove. A side support is fixedly mounted on the side of the slider, and a wire ring is fixedly mounted on the outer end of the side support.

[0015] By adopting the above technical solution, the guide ring provides guidance for the yarn during the winding process of the spool, so that the yarn can be evenly distributed and wound on the outer wall of the spool.

[0016] Furthermore, the slider is circular and its outer diameter is smaller than the inner diameter of the embedded circular groove. Several springs are fixedly connected between the slider and the inner wall of the embedded circular groove.

[0017] Furthermore, the spring is made of weather-resistant stainless steel.

[0018] By adopting the above technical solution, the use of stainless steel weather-resistant material for the spring enhances its durability.

[0019] Furthermore, the motor output end rotates to the front side of the winding machine's winding mounting plate and is fixedly connected to the inner cylinder.

[0020] Furthermore, the inner diameter of the internal thread opening is smaller than the inner diameter of the inner cylinder, and an internal hexagonal opening is provided at the outer end of the threaded column.

[0021] By adopting the above technical solution, the internal hexagonal socket is designed to facilitate the rotation of the stud by using an internal hexagonal wrench.

[0022] Compared with related technologies, the anti-breakage device for winding machines proposed in this utility model has the following advantages:

[0023] In this utility model, the winding anti-breakage device for a winding machine uses a clamping mechanism to adjust and drive the threaded column to rotate, causing the arc-shaped guide block on the inner end of the rotating column to slide inside the rotating groove, thereby driving the rotating bar plate to rotate. This causes the height of the flipping protrusion surface on the outer end of the rotating bar plate to change in reverse, thus adapting to the clamping effect on winding drums of different inner diameters, thereby enhancing the applicability of this utility model.

[0024] In addition, this utility model is equipped with an anti-breakage mechanism. In the anti-breakage mechanism, the cooperation design of the mounting plate, the embedded circular groove, the slider, the spring, the side support and the guide ring allows the slider to slide inside the embedded circular groove. While sliding, the side has the rebound force of the spring. When the guide ring is subjected to excessive tension during the guiding of the yarn, the guide ring drives the slider to slide adaptively inside the embedded circular groove to change the relative position of the guide ring, thereby reducing the tension effect during the guiding process. It has an adaptive adjustment capability, prevents yarn breakage and enhances practicality. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figure 1-7 A winding machine anti-breakage device includes a winding machine winding mounting plate 1, a motor 4 fixedly mounted on the rear side of the winding machine winding mounting plate 1, and a clamping mechanism 5 provided on the front side of the winding machine winding mounting plate 1. The clamping mechanism 5 includes an inner cylinder 51. The output end of the motor 4 rotates to the front side of the winding machine winding mounting plate 1 and is fixedly connected to the inner cylinder 51. Several rotating grooves 52 are evenly distributed on the side wall of the inner cylinder 51. A rotating strip plate 53 is rotatably mounted inside the rotating groove 52. An internal threaded port 56 is provided at the outer port of the inner cylinder 51. A threaded post 57 is screwed into the inner side of the internal threaded port 56. A rotating post 59 is rotatably mounted on the inner end of the threaded post 57. An arc-shaped guide block 510 is fixedly mounted on the side wall of the rotating post 59 and slides and engages with the inner side of the rotating groove 52.

[0035] In this embodiment, spring 84 is made of weather-resistant stainless steel.

[0036] The above structural design, along with the use of stainless steel weather-resistant material for spring 84, enhances its durability.

[0037] In this embodiment, the inner diameter of the internal threaded opening 56 is smaller than the inner diameter of the inner cylinder 51, and the outer end of the threaded column 57 is provided with an internal hexagonal opening 58.

[0038] With the above structure, the inner diameter of the internal threaded opening 56 is smaller than the inner diameter of the inner cylinder 51, so that when the threaded column 57 rotates, the thread on its outer side will not interfere with the movement of the inner wall of the inner cylinder 51. The setting of the internal hexagonal opening 58 makes it easy to drive the threaded column 57 to rotate by using an internal hexagonal wrench.

[0039] In this embodiment, a rubber strip 54 is fixedly installed on the outer side of the rotating plate 53. Horizontal grooves 55 are evenly distributed on the rubber strip 54. A winding drum 6 is sleeved on the outer side of the inner cylinder 51, and the inner wall of the winding drum 6 abuts against the outer side of the rubber strip 54.

[0040] With the above structure, the transverse groove 55 is set on the rubber strip 54, which can greatly improve the roughness of the outer surface of the rubber strip 54, thereby enabling the rubber strip 54 to stably abut against the winding drum 6 sleeved on the outer side of the column and prevent the winding drum 6 from slipping.

[0041] In this embodiment, structural folding plates 2 are fixedly installed on both sides of the winding machine winding mounting plate 1, and mounting holes 3 are evenly distributed on the structural folding plates 2.

[0042] In this embodiment, an electric telescopic rod 7 is fixedly installed on the rear side of the winding machine mounting plate 1. The output end of the electric telescopic rod 7 slides through to the front side of the winding machine mounting plate 1. An anti-breakage mechanism 8 is fixedly installed on the output end of the electric telescopic rod 7. The anti-breakage mechanism 8 includes a mounting plate 81, which is fixedly installed on the output end of the electric telescopic rod 7. An embedded circular groove 82 is opened on the inner side of the mounting plate 81. A slider 83 is slidably engaged on the inner side of the embedded circular groove 82. A side support 85 is fixedly installed on the side of the slider 83. A wire ring 86 is fixedly installed on the outer end of the side support 85. The slider 83 is circular and its outer diameter is smaller than the inner diameter of the embedded circular groove 82. Several springs 84 are fixedly connected between the slider 83 and the inner wall of the embedded circular groove 82.

[0043] With the above-described structure and the spring 84, when the slider 83 slides inside the inner circular groove 82, it is laterally subjected to the rebound force of the spring 84. When the guide ring 86 is subjected to tension during the yarn guiding process, the guide ring 86 will drive the side support 85 and the inner slider 83 to slide inside the inner circular groove 82. The rebound force of the spring 84 automatically balances the force on the guide ring, so that the slider 83 can slide freely inside the inner circular groove 82 to achieve dynamic balance, thus preventing the yarn from breaking during the guiding process.

[0044] In this invention, during use, the spool 6 is fitted onto the outside of the inner spool 51. A hex wrench is then inserted into the inner hex socket 58, and the wrench drives the threaded post 57 to rotate. This causes the threaded post 57 to slide the rotating post 59 outwards, thereby causing the arc-shaped guide block 510 on the outer wall of the rotating post 59 to slide inside the rotating groove 52. Under the gradual contact of the arc-shaped guide block 510, the rotating strip 53 gradually flips outwards, causing the rubber strip 54 on the outer side of the rotating strip 53 to contact the inner wall of the spool 6. The contact mechanism secures the yarn drum 6 to the outside of the inner drum 51. The yarn to be wound is then passed through the guide ring 86 and wound onto the outer wall of the yarn drum 6. Simultaneously, the motor 4 and the electric telescopic rod 7 are started. The motor 4 drives the yarn drum 6 to rotate synchronously, winding and taking in the yarn. The electric telescopic rod 7 drives the entire anti-breakage mechanism 8 to move back and forth, causing the guide ring 86 to move back and forth on the side of the yarn drum 6, driving the yarn to be evenly wound onto the outer wall of the yarn drum 6, ensuring uniform winding.
