Description

Technical Field

[0001] This utility model relates to the technical field of POY high-speed unwinding device, specifically a nylon take-up drum for POY high-speed unwinding device. Background Technology

[0002] In the field of high-speed POY unwinding, nylon take-up drums, as important carriers of polyester and nylon yarns, have a crucial impact on unwinding efficiency and product quality. Currently, most nylon take-up drums used in unwinding devices on the market adopt a single paper drum structure. When excess yarn or waste filaments are generated during use, the lack of a dedicated cleaning structure makes it easy for the excess yarn to become entangled on other parts of the unwinding device. This not only affects the normal operation of the equipment but may also lead to yarn knots and breakage, reducing unwinding efficiency and yarn quality. Secondly, when the yarn reaches the end of the unwinding process, the traditional paper drum structure struggles to effectively peel off the bottom yarn. Operators must spend a significant amount of time and effort manually cleaning the residual bottom yarn, which is not only cumbersome but also prone to affecting the recycling and reuse of the nylon take-up drum due to incomplete cleaning. Furthermore, the single paper drum structure cannot provide reliable fixation and guidance for the yarn during yarn switching or equipment debugging, making it difficult to accurately control the yarn direction, increasing operational difficulty and equipment debugging time. Utility Model Content

[0003] The purpose of this invention is to provide a nylon take-up drum for a high-speed POY unwinding device, in order to solve the problem mentioned in the background art that the traditional paper tube structure is difficult to effectively peel off the bottom yarn, and that operators need to spend a lot of time and effort to manually clean the residual bottom yarn.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A nylon take-up drum for a high-speed POY unwinding device includes:

[0006] A nylon take-up drum, wherein the nylon take-up drum is configured as a hollow cylindrical structure, and the outer wall of the nylon take-up drum is provided with a slack yarn cleaning groove along its length. The end of the nylon take-up drum slack yarn cleaning groove is connected to the bottom yarn stripping groove, and a switching groove is provided on the side wall of the nylon take-up drum near the bottom yarn stripping groove.

[0007] Paper tube, which is inserted and installed on the inner wall of a nylon take-up drum.

[0008] In a preferred embodiment of this utility model, the paper tube is sleeved and connected to the air expansion shaft in the POY high-speed unwinding device, and the paper tube and the nylon winding tube are tightly fitted together under the expansion action of the air expansion shaft.

[0009] In a preferred embodiment of this utility model, the outer walls at both ends of the nylon take-up drum are provided with rounded corners, the surface of the nylon take-up drum is a smooth surface, the width of the bottom yarn stripping groove is greater than that of the excess yarn cleaning groove, and the inner wall cross-section of the bottom yarn stripping groove is trapezoidal.

[0010] In a preferred embodiment of this utility model, the inner walls on both sides of the switching groove are serrated, and the serrated structures inside the switching groove are interleaved.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0012] 1. The excess yarn cleaning grooves on the outer wall of the nylon take-up drum are distributed along the length direction. During the unwinding process, they can collect excess yarn and waste yarn in time to prevent them from tangling with equipment parts and ensure a smooth unwinding process. When the remaining length of yarn is insufficient, the excess yarn can be easily pulled to the bottom yarn stripping groove by inserting the hook knife into the excess yarn cleaning groove. The bottom yarn stripping groove, with its wider width than the excess yarn cleaning groove and trapezoidal inner wall cross-section design, can effectively peel off the bottom yarn at the end of the unwinding process by using friction and guiding force. No manual cleaning is required, which greatly reduces cleaning time. Compared with the traditional paper tube structure, the unwinding efficiency is significantly improved.

[0013] 2. The serrated structure on both sides of the inner wall of the switching slot, with its staggered arrangement, provides reliable fixing points for the yarn during yarn switching or equipment debugging. This increases friction on the yarn, preventing slippage and facilitating precise control of the yarn position by operators, thus improving the stability and accuracy of yarn switching operations. Simultaneously, the nylon take-up drum and paper drum are tightly fitted together under the action of the air shaft, ensuring stable rotation of the nylon take-up drum during yarn unwinding. Furthermore, the rounded corners and smooth surfaces at both ends of the nylon take-up drum effectively reduce friction with the yarn, lowering the probability of yarn damage, ensuring yarn quality, and preventing yarn quality degradation caused by structural design defects.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Example 1: As Figures 1-4 ,include:

[0022] Nylon take-up drum 100 is configured as a hollow cylindrical structure. The outer wall of the nylon take-up drum 100 is provided with a slack yarn cleaning groove 110 along its length. The end of the slack yarn cleaning groove 110 of the nylon take-up drum 100 is connected to the bottom yarn stripping groove 120. A switching groove 130 is provided on the side wall of the nylon take-up drum 100 near the bottom yarn stripping groove 120.

[0023] Paper tube 200 is inserted and installed on the inner wall of nylon take-up drum 100.

[0024] The specific application scenario of this embodiment is as follows: In the high-speed unwinding process of POY yarn, the nylon take-up drum 100 is the core component. The nylon take-up drum 100 is used to take up polyester and nylon yarns. The hollow cylindrical structure of the nylon take-up drum 100 provides installation space for the paper tube 200. The paper tube 200 is inserted into the inner wall of the nylon take-up drum 100 and cooperates with the air shaft to achieve a stable installation. The excess yarn cleaning grooves 110 on the outer wall of the nylon take-up drum 100 are distributed along the length direction. After the yarn is wound around the outer wall of the nylon take-up drum 100, the yarn on the surface of the nylon take-up drum 100 is used in the next growth line. When the remaining length of the yarn is insufficient to maintain use, the tip of the hook is inserted into the inner wall of the excess yarn cleaning groove 110 to pull the excess yarn on the outer wall of the nylon take-up drum 100, so that the yarn is cut or pulled out to the bottom yarn stripping groove 120. Then, it is convenient for the operator to remove the remaining yarn at the bottom yarn stripping groove 120. The nylon take-up drum 100 is removable, facilitating its recycling and reuse. Its width, exceeding that of the excess yarn cleaning groove 110, and its trapezoidal inner wall cross-section design make it easy for operators to perform manual operations, improving operational convenience. It also prevents yarn from accumulating at the bottom yarn stripping groove 120, further enhancing operational efficiency and work effectiveness. It effectively strips the bottom yarn from the unwound end. The nylon take-up drum 100 is made of reusable plastic. When the bottom yarn passes through the bottom yarn stripping groove 120, the friction and guiding force generated by the groove's special structure allow it to smoothly detach from the surface of the nylon take-up drum 100. The switching groove 130 is located on the side wall of the nylon take-up drum 100 near the bottom yarn stripping groove 120. During yarn switching or equipment debugging, operators can conveniently adjust the yarn direction and position through the switching groove 130 to switch between different working states.

[0025] Example 2: Figures 1-4 The paper tube 200 is connected to the air shaft in the POY high-speed unwinding device. The paper tube 200 and the nylon take-up drum 100 are tightly fitted together under the expansion of the air shaft. The outer walls at both ends of the nylon take-up drum 100 are rounded. The surface of the nylon take-up drum 100 is smooth. The width of the bottom yarn stripping groove 120 is greater than that of the excess yarn cleaning groove 110. The inner wall cross-section of the bottom yarn stripping groove 120 is trapezoidal. The inner walls on both sides of the switching groove 130 are serrated. The serrated structures inside the switching groove 130 are interspersed.

[0026] The specific application scenario of this embodiment is as follows: The paper tube 200 is fitted with the air shaft of the POY high-speed unwinding device. When the air shaft expands, it exerts outward pressure on the paper tube 200, causing the paper tube 200 to fit tightly against the inner wall of the nylon take-up drum 100. This ensures that the nylon take-up drum 100 can rotate synchronously and stably with the air shaft during the unwinding process, avoiding uneven unwinding or malfunctions due to looseness. The rounded corners and smooth surfaces of the outer walls at both ends of the nylon take-up drum 100 reduce friction with the yarn during the unwinding process, lowering the probability of yarn damage and ensuring the smoothness of the yarn. On the one hand, it improves yarn quality; on the other hand, it prevents sharp edges from snagging on yarn or excess yarn, thus enhancing the safety of equipment operation. The width and trapezoidal inner wall of the bottom yarn stripping groove 120 enable more efficient bottom yarn stripping, increasing the effective area on the bottom yarn and ensuring complete stripping. The serrated structure on both sides of the inner wall of the switching groove 130, which is staggered, increases the friction on the yarn during yarn switching operations, making it less likely for the yarn to slip within the switching groove 130. This facilitates precise control of the yarn position by the operator, improving the stability and accuracy of yarn switching operations.

[0027] The working principle of this utility model is as follows: When used by those skilled in the art, the hollow cylindrical nylon take-up drum 100 is nested inside the paper drum 200 and cooperates with the air expansion shaft. The expansion shaft expands to make the two fit tightly together and rotate synchronously. The excess yarn cleaning groove 110 on the outer wall of the nylon take-up drum 100 can collect excess yarn and waste yarn during unwinding. The bottom yarn stripping groove 120 at the end is wider and has a trapezoidal inner wall, which can peel off the bottom yarn through friction and guiding force when there is insufficient yarn remaining. The serrated structure on the inner walls of the switching groove 130 near the bottom yarn stripping groove 120 is interlaced, which facilitates fixing and adjusting the yarn position during yarn switching or equipment debugging. The rounded corners and smooth surfaces at both ends of the nylon take-up drum 100 can reduce friction with the yarn during unwinding, reduce the probability of yarn damage, and improve the safety of equipment operation.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
