Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting, and in particular to a brush lifting mechanism for a flat knitting machine. Background Technology
[0002] In the knitting industry, the flat knitting machine is an important piece of production equipment. Traditional flat knitting machine brushes are mostly of a fixed structure, and their height and position cannot be adjusted according to changes in the knitting process. In actual knitting, different stages may require the brush to be in different positions; for example, the optimal distance between the brush and the knitting needles differs between the cast-on and cast-off stages. Fixed brushes cannot meet this need, resulting in poor cleaning or assistance effects at certain stages, which in turn affects knitting quality and can easily lead to problems such as missed stitches and yarn tangling. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a brush lifting mechanism for a flat knitting machine, based on the current state of the technology.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a brush lifting mechanism for a flat knitting machine, including a fixed frame, a brush drive motor mounted on the fixed frame, and a circumferential lifting brush mechanism. The circumferential lifting brush mechanism includes a lifting plate, a brush clamp mounted at the lower end of the lifting plate, transmission gears arranged on both sides of the fixed frame, and a lifting gear mounted on the upper end of the transmission gear. The brush drive motor has an output shaft, on which a drive gear is arranged. The output shaft passes through the fixed frame and is connected to the transmission gear through the drive gear. A rotating block extends from the lifting gear. When the output shaft rotates, it drives the drive gear and the transmission gear to sequentially transmit power to the lifting gear. The lifting gear drives the lifting plate to move circumferentially through the rotating block.
[0005] Preferably, the lifting plate is arranged in a Π shape, the lifting plate has an opening, and the brush clamp is arranged at the lower end of the lifting plate along the opening.
[0006] The effects achieved by the above components are as follows: the lifting plate is Π-shaped with an opening. The Π-shaped structure gives the lifting plate good mechanical properties, making it less prone to deformation when bearing the brush and during operation, thus ensuring the stability of the brush lifting. At the same time, the opening design facilitates the installation and disassembly of the brush clamp, making the operation more convenient and efficient when the brush needs to be replaced or maintained, reducing equipment downtime and improving overall production efficiency.
[0007] Preferably, the brush clamp includes a fixing strip, a first clamping plate, and a second clamping plate disposed on the first clamping plate, wherein the first clamping plate is disposed on the lifting horizontal plate by means of the fixing strip.
[0008] The aforementioned components achieve the following effects: by setting up a brush clamp including a fixing strip, a first clamping plate, and a second clamping plate, the structure is simple and practical. The fixing strip is used to securely connect the first clamping plate to the lifting horizontal plate, ensuring that the brush will not shift due to vibration or other factors during operation. The first and second clamping plates facilitate the installation and fixation of the brush, firmly holding it in place and ensuring that the brush can stably perform cleaning or auxiliary weaving during operation, thus improving the reliability of the brush's work.
[0009] Preferably, a fixing bracket is provided on one side of the brush drive motor on the fixing frame, and a detection unit is provided on the fixing bracket.
[0010] The aforementioned components achieve the following effects: A fixed bracket is installed on the fixed frame along one side of the brush drive motor, and a detection unit is mounted on it. The detection unit can monitor the working status of the brush in real time, such as the degree of brush wear and whether it is loose. This allows for advance maintenance or replacement of the brush, preventing a decline in knitting quality due to brush problems, extending the service life of the brush and the entire mechanism, ensuring the stable operation of the flat knitting machine, and reducing production losses caused by equipment failure.
[0011] Preferably, the first clamping plate and the second clamping plate are connected by bolts, and a brush is provided between the first clamping plate and the second clamping plate.
[0012] The aforementioned components achieve the following effect: the first and second clamping plates are connected and clamp the brush via bolts, a simple, direct, and reliable fixing method. The bolt connection facilitates easy disassembly and installation of the brush, allowing for quick replacement when the brush becomes worn. Furthermore, the bolt connection allows for flexible adjustment of the clamping force based on factors such as brush thickness, ensuring the brush remains stable during operation and effectively improving the flexibility and reliability of brush fixing.
[0013] Preferably, one end of the fixing frame extends and bends along the direction of the brush drive motor to form a fixing end, and a fixing hole is provided on the fixing end.
[0014] The effect achieved by the above components is as follows: one end of the fixed frame extends and bends along the direction of the brush drive motor to form a fixed end, and a fixing hole is opened at the fixed end. Through the fixing hole, the mechanism can be firmly installed on the flat knitting machine, ensuring that the brush lifting mechanism will not be displaced due to vibration or other reasons during the operation of the flat knitting machine, thereby ensuring that the brush is always in an accurate working position, providing a solid foundation for the stable knitting of the flat knitting machine, and further improving the stability of knitting and product quality.
[0015] Compared with existing technologies, the advantages of this invention are as follows: by setting up a fixed frame, a brush drive motor, and a circumferential lifting brush mechanism, and using a multi-stage gear transmission method—that is, the drive gear, transmission gear, and lifting gear sequentially transmit power—the stability and reliability of power transmission are ensured. This allows the lifting plate to achieve circumferential lifting, and compared with traditional brush lifting methods, the brush position can be controlled more flexibly and precisely, greatly improving the knitting adaptability and knitting quality of the flat knitting machine.

[0026] In this embodiment 1,
[0027] like Figures 1 to 4 As shown, this utility model provides a lifting mechanism for a brush 15 on a flat knitting machine, including a fixed frame 1, a brush drive motor 2 mounted on the fixed frame 1, and a circumferential lifting brush mechanism 3.

A rotating block 9 extends from the lifting gear 7. When the output shaft rotates, it drives the drive gear 8 and the transmission gear 6 to sequentially transmit power to the lifting gear 7. The lifting gear 7 drives the lifting plate 4 to move circumferentially up and down via the rotating block 9.
[0028] By setting up a fixed frame 1, a brush drive motor 2, and a circumferential lifting brush mechanism 3, and using a multi-stage gear transmission method—that is, the drive gear 8, transmission gear 6, and lifting gear 7—power transmission stability and reliability are ensured. This allows the lifting plate 4 to achieve circumferential lifting, and compared to traditional brush lifting methods, it allows for more flexible and precise control of the brush 15 position, greatly improving the knitting adaptability and knitting quality of the flat knitting machine.
[0029] The lifting plate 4 is arranged in a Π shape and has an opening. The brush clamp 5 is arranged at the lower end of the lifting plate 4 along the opening.
[0030] The lifting plate 4 is Π-shaped with an opening. The Π-shaped structure gives the lifting plate 4 good mechanical properties, making it less prone to deformation when bearing the brush 15 and during operation, thus ensuring the stability of the brush lifting.

The first clamping plate 11 and the second clamping plate 12 facilitate the installation and fixation of the brush 15, firmly clamping it and ensuring stable cleaning or auxiliary weaving operations, thus improving the reliability of the brush 15's operation.
[0033] A fixing bracket 13 is provided on one side of the brush drive motor 2 on the fixing frame 1, and a detection unit 14 is provided on the fixing bracket 13.
[0034] A fixed bracket 13 is set on one side of the brush drive motor 2 on the fixed frame 1, and a detection unit 14 is installed on it. The detection unit 14 can monitor the working status of the brush 15 in real time, and can maintain or replace the brush 15 in advance to avoid the decline in knitting quality caused by the brush 15, extend the service life of the brush 15 and the entire mechanism, and at the same time ensure the stable operation of the flat knitting machine and reduce production losses caused by equipment failure.
[0035] The first clamping plate 11 and the second clamping plate 12 are connected by bolts, and a brush 15 is provided between the first clamping plate 11 and the second clamping plate 12.
[0036] The first clamping plate 11 and the second clamping plate 12 are connected by bolts to clamp the brush 15. This fixing method is simple, direct, and reliable. The bolt connection facilitates easy disassembly or installation of the brush 15, and allows for quick replacement when the brush 15 becomes worn. Furthermore, the bolt connection allows for flexible adjustment of the clamping force based on factors such as the thickness of the brush 15, ensuring the brush 15 remains stable during operation and effectively improving the flexibility and reliability of the brush 15's fixation.
[0037] One end of the fixing frame 1 extends and bends along the direction of the brush drive motor 2 to form a fixing end 16, and a fixing hole 17 is provided on the fixing end 16.
[0038] One end of the fixed frame 1 extends and bends along the direction of the brush drive motor 2 to form a fixed end 16, and a fixing hole 17 is opened in the fixed end 16. Through the fixing hole 17, the mechanism can be firmly installed on the flat knitting machine, ensuring that the brush 15 lifting mechanism will not be displaced due to vibration or other reasons during the operation of the flat knitting machine, thereby ensuring that the brush 15 is always in an accurate working position, providing a solid foundation for the stable knitting of the flat knitting machine, and further improving the stability of knitting and product quality.
[0039] In this embodiment 2,
[0040] like Figures 1 to 4 As shown, this utility model utilizes a fixed frame 1, a brush drive motor 2, and a circumferential lifting brush mechanism 3 working in synergy. Multi-stage gear transmission enables precise circumferential lifting of the brush 15, meeting various knitting requirements. A Π-shaped lifting horizontal plate 4 with an opening facilitates the installation of the brush clamp 5, ensuring structural stability. The brush clamp 5 is composed of a fixing strip 10, a first clamping plate 11, and a second clamping plate 12, secured with bolts to the brush 15, making installation and replacement convenient and secure.

The fixed end 16 and fixing hole 17 at one end of the fixed frame 1 facilitate stable installation of the mechanism on the flat knitting machine, ensuring stable and reliable operation and comprehensively improving the knitting quality and efficiency of the flat knitting machine.
[0041] In this embodiment 3,
[0042] like Figures 1 to 4 As shown, the working principle of this utility model is as follows:
[0043] In operation, the brush drive motor 2 starts, and its output shaft rotates accordingly, causing the drive gear 8 mounted on the output shaft to rotate as well. The drive gear 8 meshes with the transmission gears 6 arranged along both sides of the fixed frame 1. Due to the transmission between the gears, the rotational power of the drive gear 8 is transmitted to the transmission gear 6, causing the transmission gear 6 to rotate around its own axis. The transmission gear 6 then meshes with the lifting gear 7 located at its upper end, further transmitting power to the lifting gear 7, causing it to rotate. The rotating block 9 extending from the lifting gear 7 performs a circular motion as the lifting gear 7 rotates. Since the rotating block 9 is connected to the lifting horizontal plate 4, the circular motion of the rotating block 9 is converted into the circumferential lifting motion of the lifting horizontal plate 4, realizing the circumferential lifting of the brush 15 and greatly improving the knitting adaptability and knitting quality of the flat knitting machine.
