Description

Technical Field

[0001] The utility model relates to the technical field of computer knitting, in particular to a brush assembly and a flat knitting machine. Background Art

[0002] In the modern textile industry, in order to improve production efficiency, computer knitting machines are often used for knitting. During the working process of the computer knitting machine, in order to ensure that the needle hook of the knitting needle can smoothly hook the yarn in the yarn mouth, it is necessary to use a brush to scrape the needle tongue to avoid missing needles.

[0003] In the prior art, such as Figure 1 As shown, since the position of the brush is relatively fixed and cannot be adjusted, when the flip-joining needle is working, the brush cannot avoid the knitting needle. At this time, the brush will interfere with the flip-joining needle, thereby affecting the overall reliability and stability of the flip-joining needle. In addition, since the brush constantly scrapes against the knitting needle, the wear of the bristles increases, which reduces the service life of the brush and leads to an increase in production costs.

[0004] It should be noted that the information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to a person skilled in the art.

[0033] See also Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of a brush assembly provided by an embodiment of the utility model in a zero position; Figure 3 yes Figure 2 A structural diagram of the perspective of FIG. In order to achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a brush assembly. Figure 2 As shown in FIG. 1 , the brush assembly includes a fixing seat 10 , a motor 20 , a lifting mechanism 30 and a brush 40 .

[0034] The motor 20 is disposed in the fixing seat 10, and the motor 20 has a first end 21 and a second end 22 opposite to each other, and the first end 21 and the second end 22 respectively penetrate the fixing seat 10 and extend out of the fixing seat 10. Preferably, the motor 20 is a stepping motor.

[0035] The lifting mechanism 30 is disposed on the fixed base 10, and the lifting mechanism 30 is connected to the first end 21 of the motor 20 to drive the lifting mechanism 30 to move, and the lifting mechanism 30 is movably connected to the fixed base 10.

[0036] The end 41 of the brush 40 is connected to the lifting mechanism 30 , and the brush head 42 of the brush 40 is opposite to the knitting needle 50 .

[0037] In specific implementation, when the lifting mechanism 30 moves, it can drive the brush 40 to move synchronously, so that the brush head 42 of the brush 40 contacts the knitting needle 50, which is used to scrape the needle tongue on the knitting needle 50, ensuring that the needle hook of the knitting needle 50 can smoothly hook the yarn and avoid the problem of missing needles.

[0038] In some preferred embodiments, the lifting mechanism 30 includes a lifting gear 31 and a lifting gear row 32, the lifting gear 31 is fixed on the first end 21 of the motor 20, the lifting gear row 32 is meshed with the lifting gear 31 for transmission, and the lifting gear row 32 is connected to the brush 40. Preferably, a slide groove 60 is provided on the lifting gear row 32, and a limiting block 70 is provided on the fixed seat 10, and the width of the slide groove 60 is greater than the width of the limiting block 70, so that the limiting block 70 can be located inside the slide groove 60, and the limiting block 70 is slidably connected to the slide groove 60, so that when the lifting gear row 32 moves, the limiting block 70 limits and supports the airway of the lifting gear row 32 through the slide groove 60.

[0039] In specific implementation, when the motor 20 rotates, the lifting gear 31 rotates, and the lifting gear row 32 meshes with the lifting gear 31 for transmission, and the lifting gear row 32 moves, thereby pushing the brush 40 to move, so that the brush head 42 of the brush 40 moves toward the knitting needle 50.

[0040] In some preferred embodiments, the brush assembly further comprises a brush fixing seat 80 and a brush clamping plate 90, the brush fixing seat 80 is connected to the lifting gear row 32, the brush clamping plate 90 is fixed on the brush fixing seat 80, and the brush clamping plate 90 is movably connected to the end 41 of the brush 40. Preferably, an adjusting member 100 is provided on the brush clamping plate 90, and the adjusting member 100 is movably connected to the brush fixing seat 80 and the brush clamping plate 90 respectively, and is used to adjust the distance between the brush clamping plate 90 and the brush fixing seat 80.

[0041] During specific implementation, one end of the brush clamp 90 is fixed to the brush holder 80, and a space is formed between the other end of the brush clamp 90 and the brush holder 80. The end 41 of the brush 40 is placed in the space. The distance between the brush clamp 90 and the brush holder 80 is adjusted by the adjustment member 100, so that the brush clamp 90 firmly clamps the end 41 of the brush 40.

[0042] In some preferred embodiments, the bristles of the brush 40 are closely spaced.

[0043] In some preferred embodiments, Figure 3 As shown, the brush assembly further includes another zero position sensor 110 and a zero position sensor block, the zero position sensor 110 is arranged on a side of the fixing base 10 away from the lifting mechanism 30, and the zero position sensor block 120 is connected to the second end 22 of the motor 20. Preferably, the zero position sensor block 120 is a rectangular parallelepiped, and one end of the zero position sensor block 120 is connected to the second end 22 of the motor 20.

[0044] In a specific implementation, the zero position sensing block 120 is in a rectangular parallelepiped shape, one end of which is connected to the second end 22 of the motor 20 . When the motor 20 rotates, it can drive the zero position sensing block 120 to swing.

[0045] When the motor 20 rotates to drive the brush 40 into the working position, the zero position sensing block 120 swings and leaves the sensing range of the zero position sensor 110, which is the working position state. When the motor 20 rotates to drive the brush 40 to retract, it drives the zero position sensing block 120 to swing and enter the sensing range of the zero position sensor 110. When the zero position sensor 110 senses the zero position sensor 120, it is the zero position state.

[0046] In some preferred embodiments, the utility model also provides a flat knitting machine, comprising a plurality of the above-mentioned brush assemblies.

[0047] In the specific implementation, the brush assembly is fixed on the knitting machine through the fixing seat 10. In the initial state, the brush assembly is in a zero position (such as Figure 2 , Figure 3 When the knitting needles are working, the motor 20 rotates, driving the lifting gear 31 to rotate. Due to the meshing transmission relationship between the lifting gear 31 and the lifting gear row 32, the lifting gear row 32 moves under the drive of the lifting gear 31, thereby driving the brush 40 to move toward the knitting needles 50, so that the brush head 42 of the brush 40 contacts the knitting needles 50, as shown in FIG. Figure 4 and Figure 5 As shown, the brush assembly is in the working position, at which time the brush head 42 can scrape the needle tongue of the knitting needle 50 to ensure that the needle hook of the knitting needle 50 can smoothly hook the yarn to avoid missing needles.

[0048] When the needle is turned over, the motor 20 rotates in the opposite direction, driving the lifting gear row 32 to move in the opposite direction, driving the brush 40 to retract, and the brush head 41 of the brush 40 is separated from the knitting needle 50. At this time, the brush assembly returns to the zero position state, preventing the brush 40 from interfering with the needle turning operation, and also preventing the brush head 41 from scratching the knitting needle 50 for a long time, thereby reducing the service life.

[0049] To sum up, the brush assembly and knitting machine provided by the utility model are compared with the prior art. A lifting device is arranged between the fixed seat and the brush to drive the brush to rise and fall. When the knitting needles are working, the lifting device moves downward to the working position, and the brush can scrape the needle tongue of the knitting needle, so that the needle hook of the knitting needle can smoothly hook the yarn in the yarn mouth. When the flip needle is working, the lifting device moves upward to the zero position, and the brush leaves the knitting needle working position and avoids the knitting needle, thereby preventing the brush from interfering with the flip needle work and also avoiding the problem of the bristles scraping against the knitting needles for a long time and reducing the service life of parts.

[0050] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the utility model can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
