Description

Technical Field

[0001] This utility model relates to the field of monofilament processing technology, specifically a special unit for producing monofilaments with flexible tension control. Background Technology

[0002] Monofilament refers to a single long filament with a small count produced by a single-hole spinneret in the production of chemical fibers. Monofilament is characterized by its lightness, thinness, high transparency, and good hand feel.

[0003] In the existing technology, the tension of long-distance monofilament conveying cannot be controlled and adjusted in monofilament textile processing, which can easily lead to the risk of monofilament breakage during the conveying process and affect the quality of monofilament textile processing.

[0004] Therefore, it is necessary to design a special unit for the production of monofilaments with flexible tension control to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a special unit for the production of flexible tension-controlled monofilaments to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A special unit for producing flexible tension-controlled monofilament includes a first fixed frame and a second fixed frame. The first fixed frame is equipped with a plurality of rotatable guide wheels. The second fixed frame has a notch, and a tension adjustment mechanism is provided inside the notch and extending to the outside. A traction wheel is provided below the tension adjustment mechanism, and a monofilament is placed between the traction wheel and the tension adjustment mechanism.

[0008] As a preferred embodiment of this utility model, the tension adjustment mechanism includes a drive cylinder fixedly installed on the top of the second fixed frame. A piston rod is connected to the lower output end of the drive cylinder. A first transverse connecting frame and a second transverse connecting frame are respectively sleeved and fixedly installed on the piston rod. A baffle is fixedly connected to the front side of the first transverse connecting frame, and a detection mechanism is provided below the first transverse connecting frame.

[0009] As a preferred embodiment of this utility model, the detection mechanism includes a spring sheet that is abutted and installed below the first transverse connecting frame. A tension sensor is connected below the spring sheet, and a mounting plate is connected to the bottom of the tension sensor. A pressure roller is mounted below the mounting plate via a bracket.

[0010] As a preferred embodiment of this utility model, the mounting plate has sliding holes at its four corners, and sliding rods are slidably connected inside the sliding holes. The upper part of the sliding rods is threaded to the lower part of the first transverse connecting frame, and a limit block is fixedly installed at the bottom of the sliding rods to prevent the mounting plate from detaching from the sliding rods during the sliding process.

[0011] As a preferred embodiment of this utility model, the pressure wheel and the traction wheel are of the same type of wheel structure, and the two are located in the same vertical direction.

[0012] As a preferred embodiment of this utility model, both the first transverse connecting frame and the second transverse connecting frame can slide up and down inside the notch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a flexible tension control monofilament production unit is designed. During monofilament production, the operation of a drive cylinder can extend or shorten the piston rod below, thereby moving the first and second transverse connecting frames upward or downward. This, in turn, moves the traction wheel below up and down, thus altering the tension of the monofilament passing over the traction wheel. This avoids the risk of monofilament breakage due to excessive tension. Simultaneously, the elastic deformation of the spring in the detection mechanism allows the tension sensor to monitor the tension changes of the monofilament. In conjunction with the drive cylinder, this achieves precise tension adjustment, thereby improving the quality of the monofilament textile processing. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A special unit for producing monofilaments with flexible tension control includes a first fixed frame 1 and a second fixed frame 2. The first fixed frame 1 is equipped with a plurality of rotatable guide wheels 3, which are used to guide and convey the monofilaments. The second fixed frame 2 has a notch 4, and a tension adjustment mechanism 5 is provided inside the notch 4 and extending to the outside. A traction wheel 6 is provided below the tension adjustment mechanism 5, and a monofilament is placed between the traction wheel 6 and the tension adjustment mechanism 5.

[0026] Specifically, the tension adjustment mechanism 5 includes a drive cylinder 51 fixedly installed on the top of the second fixed frame 2. A piston rod 52 is connected to the lower output end of the drive cylinder 51. A first transverse connecting frame 53 and a second transverse connecting frame 54 are respectively sleeved and fixedly installed on the piston rod 52. Both the first transverse connecting frame 53 and the second transverse connecting frame 54 can slide up and down inside the notch 4. A baffle 55 is fixedly connected to the front side of the first transverse connecting frame 53. A detection mechanism 56 is provided below the first transverse connecting frame 53.

[0027] The detection mechanism 56 includes a spring piece 561 that abuts against the lower part of the first transverse connecting frame 53. A tension sensor 562 is connected to the lower part of the spring piece 561. A mounting plate 563 is connected to the bottom of the tension sensor 562. A pressure roller 564 is mounted on the lower part of the mounting plate 563 via a bracket.

[0028] In this embodiment, the piston rod 52 drives the first transverse connecting frame 53 and the second transverse connecting frame 54 to slide up and down in the notch 4 by driving the cylinder 51, thereby driving the traction wheel 6 below to move up and down, thereby changing the tension of the monofilament passing through the traction wheel 6, avoiding the risk of the monofilament breaking due to excessive tension.

[0029] When the first transverse connecting frame 53 slides up and down, it causes the spring piece 561 to deform, which is then converted into an electrical signal by the tension sensor 562 for output, so as to achieve accurate detection of tension or position.

[0030] The mounting plate 563 has sliding holes at its four corners, and sliding rods are slidably connected inside the sliding holes. The upper part of the sliding rods is threaded to the lower part of the first transverse connecting frame 53. A limit block is also fixedly installed at the bottom of the sliding rods to prevent the mounting plate 563 from detaching from the sliding rods during sliding. The pressure roller 564 and the traction roller 6 are of the same type of wheel structure and are located in the same vertical direction. The single filament is transported in the cavity between the pressure roller 564 and the traction roller 6.

[0031] The working process of this utility model is as follows: When using this flexible tension control monofilament production unit, the monofilament can be conveyed through multiple guide wheels 3 and traction wheels 6. During the conveying process, the piston rod 52, driven by the drive cylinder 51, drives the first transverse connecting frame 53 and the second transverse connecting frame 54 to slide up and down within the notch 4, thereby driving the traction wheel 6 below to move up and down, thus changing the tension of the monofilament passing through the traction wheel 6 and avoiding the risk of monofilament breakage due to excessive tension. At the same time, the elastic deformation of the spring sheet 561 enables the tension sensor 562 to monitor the tension change of the monofilament. Furthermore, the tension sensor 562 can transmit the detected data to the control terminal in real time. The control terminal can then send a signal to the control terminal of the drive cylinder 51 based on the tension data to control the piston rod 52 of the drive cylinder 51 to extend or retract according to the tension change, achieving the purpose of precise tension adjustment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
