Description

Technical Field

[0001] The utility model relates to the technical field of high-strength polypropylene yarn production, in particular to a take-up device for high-strength polypropylene yarn production. Background Art

[0002] High-strength polypropylene yarn production is a rope made of polypropylene high-strength yarn. Due to its high breaking strength, wear resistance, corrosion resistance, light weight and safety, low price, wide variety and customizable colors, it is mainly used in construction, transportation, agriculture, fishery, sports and other industries. After the high-strength polypropylene yarn is produced, it needs to be reeled through a take-up device.

[0003] After the commonly used automatic wire-winding device completes the wire-drawing production line, the wire-drawing production line head is usually tied directly to the bobbin. During the operation, it is easy to mistakenly tie the wire head into a knot, which makes it difficult to untie the knot, thereby affecting the subsequent winding operation. Utility Model Content

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Reference Figure 1-2A take-up device for high-strength polypropylene yarn production includes a mounting frame 1 and a wire drum 2 mounted on the mounting frame 1, a wire arrangement mechanism 3 and a wire clamping mechanism 4. The wire clamping mechanism 4 includes a fixed plate 401, a fixed shaft 402, a cutting seat 403, a connecting rod 404, an electric cylinder 405, a bottom plate 406, a limit plate 407, a nut 408, a spring 409, a fixed column 410 and a cutting knife 411. There are two fixed shafts 402, which are fixed by the fixed plate 401. The cutting seat 403 is fixed on the fixed plate 401. The electric cylinder 405 is two cloth Placed at the bottom of the fixed plate 401, the bottom plate 406 is fixed to the output end of the electric cylinder 405, the connecting rod 404 is fixed to the bottom plate 406 and extends upward through the fixed shaft 402, the limiting plate 407 is set above the fixed shaft 402 and is fixed to the stud 4041 of the connecting rod 404 by the nut 408, the side plate of the cutting knife 411 slides along the fixed column 410 fixed to the limiting plate 407, and the spring 409 is mounted on the lower end of the fixed column 410 and fixed to the limiting plate 407 to elastically support the cutting knife 411;

[0022] (It should be noted that Figure 1 The driving motors for driving 2 and 3 on center 1 are not shown. 3 adopts the existing wire arrangement mechanism to realize the wire arrangement operation during the winding process of 2; the device needs to be installed on the external support for use).

[0023] The wire drum 2 is mounted on the drive drum at the output end of the drive motor. After the polypropylene yarn passes through the corresponding position of the wire arrangement mechanism 3, it passes between the fixed shaft 402 and the limit plate 407 and is connected to the wire drum 2. After that, the wire drum 2 and the wire arrangement mechanism 3 can be controlled to operate. The wire arrangement mechanism 3 assists the wire drum 2 in winding the polypropylene yarn.

[0024] After the winding of the wire drum 2 is completed, the electric cylinder 405 can be driven to push the bottom plate 406 to move downward. The bottom plate 406 drives the limit plate 407 to move downward through the connecting rod 404, so that the limit block 4071 is embedded in the fixed shaft 402. At this time, the polypropylene yarn can be clamped by the fixed shaft 402 and the limit plate 407. At this time, the cutting knife 411 can be pressed to the cutting seat 403, and the polypropylene yarn can be cut by the cutting knife 411;

[0025] A nut 408 on the upper end surface of the limiting plate 407 can be slightly turned to loosen the limiting plate 407 on the side close to the reel 2 to limit the polypropylene yarn. The reel 2 can then be removed. After replacing the new reel 2, the electric cylinder 405 can be driven to retract the piston rod, pulling 406 to move upward, pushing the limiting plate 407 to move upward synchronously, and the subsequent polypropylene yarn can be pulled onto the reel 2 for continued winding.

[0026] The device can clamp and cut the polypropylene yarn at any position where it stays during the winding process of the reel 2, and can conveniently fix the polypropylene yarn. There is no need to manually bind the polypropylene yarn at a certain position when replacing the reel 2, which avoids the operator from accidentally tying the thread end into a knot, making it more inconvenient to open.

[0027] Two limit grooves 4021 are provided on the fixed shaft 402, and a limit block 4071 protrudes from the bottom of the limit plate 407 and can be embedded in the limit groove 4021; the length of the fixed shaft 402 is set to be longer than the length of the limit plate 407, and the limit plate 407 can be moved downward so that the limit block 4071 is embedded in the limit groove 4021, thereby clamping and limiting the polypropylene yarn.

[0028] The limit plate 407 is provided with an arc structure; because nuts 408 are provided on the upper and lower sides of the limit plate 407, the nut 408 on the lower side of the limit plate 407 can be ensured not to contact the fixed shaft 402, thereby avoiding affecting the limit block 4071 from being normally embedded in the limit groove 4021.

[0029] A notch is provided in the middle of the cutting seat 403, and is arranged correspondingly to the cutting knife 411 above and below; in the initial state, the lowest point of the cutting knife 411 is higher than the lowest point of the limiting plate 407. When cutting the polypropylene yarn, the cutting knife 411 is pressed, and its side plate presses the spring 409 downward, so that the bottom end of the cutting knife 411 is lower than the lowest end of the limiting plate 407. When the cutting knife 411 is inserted into the middle groove of the cutting seat 403, the polypropylene yarn can be cut.

[0030] A ring is provided at the upper end of the fixing column 410 for limiting the upward freedom of the side plate of the cutting knife 411 so that the cutting knife 411 is lifted by the elastic force of the spring 409 when not in use so that its lowest end is higher than the lowest end of the limiting plate 407.

[0031] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
