Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding device technology, specifically to a monofilament drawing and winding device. Background Technology
[0002] In the monofilament production and processing of industries such as chemical fibers and textiles, the drawing and winding of monofilaments are crucial processes that directly affect the final product quality. To address the potential for power outages during monofilament winding, existing technologies have proposed a solution using a movable weight cylinder in the winding device. The design concept is as follows: under normal operating conditions, the weight cylinder remains relatively stable as the monofilament is conveyed; when a sudden power outage causes asynchronous rotation of the front and rear rollers, the weight cylinder presses down on the monofilament under its own weight, using the tension provided by its gravity to maintain the monofilament tension. This effectively prevents the monofilament from sagging due to sudden loss of tension or from becoming entangled on the rollers due to speed differences, thus mitigating the negative impact of power outages on the winding process to some extent. However, existing monofilament winding devices using weight cylinders suffer from significant drawbacks in practical applications, where adjusting the weight of the weight cylinder is extremely inconvenient and cannot achieve rapid and flexible weight adjustment. Therefore, this invention provides a monofilament drawing and winding device. Utility Model Content
[0003] The purpose of this invention is to provide a monofilament drawing and winding device.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A monofilament drawing and winding device: a winding machine body, wherein the winding machine body is provided with a plurality of winding shafts and a plurality of wire guide rods, wherein each wire guide rod corresponds to one of the winding shafts and its horizontal height is higher than that of the winding shafts; The tensioning mechanism includes two fixed frames fixedly connected to the end of the winding machine body, located at the top and bottom of the winding machine body respectively. Two support frames are provided between the two fixed frames. The support frames are provided with several L-shaped mounting slots. The horizontal part of the L-shaped mounting slot extends through the support frame to one side to form an opening, and the vertical part extends downward from the horizontal part. A bearing is slidably disposed in the L-shaped mounting groove, a shaft is inserted into the bearing, a weight cylinder is sleeved on the shaft, and counterweights are detachably connected to both ends; the weight cylinder is located between the two support frames, and the two counterweights are located outside the two support frames.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme, a plurality of the take-up shafts are arranged in a matrix, and the number of the L-shaped mounting slots is equal to the number of rows of the take-up shafts.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme, the edge of the L-shaped mounting groove is recessed outward to form a sliding groove with limiting parts on both sides, and the bearing is slidably fitted in the sliding groove.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme, the counterweight is a circular disc structure and is concentrically arranged with the shaft.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: The counterweights are detachably connected to both ends of the shaft, which not only avoids affecting the guide wire of the plumb bob, but also ensures that the center of gravity of the plumb bob is located at its center, thereby reducing vibration during rotation and improving stability. The counterweights located at both ends of the shaft are also easy to disassemble, allowing for the replacement of counterweights of different weights as needed. The structure is simple and installation is convenient. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0017] like Figure 1 As shown, a monofilament drawing and winding device includes: a winding machine body 1, on which a plurality of winding shafts 2 and a plurality of wire guide rods 3 are arranged, the wire guide rods 3 corresponding one-to-one with the winding shafts 2, and their horizontal height being higher than that of the winding shafts 2. The plurality of winding shafts 2 are arranged in a matrix.
[0018] It also includes tensioning mechanisms, such as Figure 2 and Figure 3 As shown, the tensioning mechanism includes two fixed frames 4 fixedly connected to the ends of the winding machine body 1, with the two fixed frames 4 located at the top and bottom ends of the winding machine body 1, respectively. Two vertically arranged support frames 5 are provided between the two fixed frames 4, and each support frame 5 has several L-shaped mounting slots 6.
[0019] The horizontal portion of the L-shaped mounting groove 6 extends through the support frame 5 to one side to form an opening, and the vertical portion extends downward from the horizontal portion, with a smooth transition at the corner of the L-shaped mounting groove 6. The edge of the L-shaped mounting groove 6 is recessed outward to form a sliding groove 11 with limiting portions on both sides, so that the edge of the L-shaped mounting groove 6 has a U-shaped structure.
[0020] A bearing 7 is slidably disposed within the L-shaped mounting groove 6. The bearing 7 is slidably fitted within the sliding groove 11 and is restricted by the limiting part, preventing it from moving left or right and detaching from the support frame 5. The bearing 7 enters the L-shaped mounting groove 6 through the opening.
[0021] like Figure 4 As shown, a shaft 8 is inserted inside the bearing 7, and a weighted cylinder 9 is fitted over the shaft 8, with counterweights 10 detachably connected to both ends. The weighted cylinder 9 is located between the two support frames 5, fitted over the shaft 8, and rotates synchronously with it. The two counterweights 10 are located outside the two support frames 5 and also rotate synchronously with the shaft 8. Preferably, the counterweights 10 are circular disc-shaped structures, concentrically arranged with the shaft 8. The circular structure of the counterweights 10 ensures balanced gravity in all directions, preventing eccentric vibration during rotation.
[0022] The counterweight 10 is detachably fixed to the shaft 8 by bolts 12. A threaded hole is provided at the end of the shaft 8, and a through hole is provided in the center of the counterweight 10. The bolt 12 passes through the through hole and engages with the threaded hole, thus achieving a detachable connection between the counterweight 10 and the shaft 8. A recessed center on the end face of the counterweight 10 forms a countersunk hole, into which the bolt 12 engages, ensuring that the bolt head does not protrude beyond the counterweight 10.
[0023] During operation, the monofilament first passes under the weight cylinder 9, then passes over the top of the cable guide rod 3, and is finally wound up by the winding shaft 2. When power failure or other situations occur, the monofilament droops, and the weight cylinder 9 is pressed down under the action of gravity, descending into the vertical section of the L-shaped mounting groove 6, so that the monofilament remains taut.
[0024] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
