Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, specifically to an oil-air mixing atomization lubrication device for computerized flat knitting machines. Background Technology

[0002] During the operation of a computerized flat knitting machine, the knitting of various patterns is completed by the needles through different trajectories of the cams. Therefore, during the knitting process, the wear of the needles and the wear of the needles and needle grooves are the main wear and tear on the moving parts. As the needles and needle grooves wear down, the corresponding cam tracks will also wear down. In order to improve the service life of the needles, needle grooves and cams, manufacturers generally use oil lubrication to ensure the working environment of the side walls of the needles and needle grooves and the cam tracks.

[0003] Manufacturers typically use manual methods, such as smearing or dripping, to apply oil at irregular intervals. However, this method, which involves spreading the oil evenly between adjacent application points using a machine head, often results in improper application, uneven lubrication, and longitudinal or transverse oil stains on the fabric, causing damage.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0029] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-4As shown, this embodiment provides an oil-air mixing atomization lubrication device for a computerized flat knitting machine, including a motor mounting base 10, a motor bracket 21, a motor 25, and a controller. The controller adopts a conventional PLC controller (or MCU controller, or microprocessor, or control chip), which has the conventional function of analyzing and comparing input signals to output corresponding control signals. One end of the motor mounting base 10 is the first end, and the other end of the motor mounting base 10 is the second end.

[0031] The motor mounting base 10 has a first mounting hole 20 penetrating through the first end and the second end. The first mounting hole 20 has an oil outlet at the position corresponding to the first end. The motor bracket 21 is disposed inside the first mounting hole 20. The motor bracket 21 includes an outer cylinder 22 and an inner cylinder 23 disposed inside the outer cylinder 22. The outer cylinder 22 and the first mounting hole 20 are arranged coaxially, and the inner cylinder 23 is arranged coaxially with the outer cylinder 22. The outer peripheral wall of the outer cylinder 22 and the inner side wall of the first mounting hole 20 are interference-fitted. An air duct is formed between the outer cylinder 22 and the inner cylinder 23, and multiple guide plates 24 are disposed between the outer cylinder 22 and the inner cylinder 23. Specifically, each guide plate 24 is distributed around the axis of the inner cylinder 23, and the plane of each guide plate 24 forms an angle with the axis of the inner cylinder 23. The motor 25 is fixedly connected inside the inner cylinder 23 and is arranged coaxially with the inner cylinder 23. The output shaft of the motor 25 passes through the motor bracket. The frame 21 is fixedly connected to an axial flow fan 26 located in the first mounting hole 20. The motor 25 and the axial flow fan 26 are arranged sequentially from the second end to the first end. The motor 25 is electrically connected to the controller. The side wall of the motor mounting base 10 is provided with an oil nozzle 27 for spraying lubricating oil into the first mounting hole 20 at the position corresponding to the axial flow fan 26. In use, one end of the oil nozzle 27 is located in the first mounting hole 20, and the other end of the oil nozzle 27 is connected to the oil filling machine. It should be noted that the oil filling machine is not part of the oil-air mixing atomization lubrication device for the computerized flat knitting machine provided in this embodiment, and needs to be configured separately during use. This utility model uses the motor 25 and the axial flow fan 26 to mix and atomize the lubricating oil with air and spray it out from the oil outlet, which can make the lubricating oil spray more evenly, have a better lubrication effect, and effectively prevent the soiling of textiles.

[0032] The axial flow wind turbine 26 includes a hub 33 and multiple blades 34 that are fixedly or integrally connected to the outer circumferential surface of the hub 33. Each blade 34 is distributed around the axis of the hub 33, and the plane of each blade 34 forms an angle with the axis of the hub 33.

[0033] The inner wall of the first end of the motor mounting base 10 is provided with a retention ring 28 arranged coaxially with the first mounting hole 20, and the inner diameter of the retention ring 28 is smaller than the diameter of the outer contour of the axial flow impeller 26. By providing the retention ring 28, the lubricating oil adhering to the inner wall of the first mounting hole 20 is prevented from being directly discharged.

[0034] A filter cover 29 is provided on the inner side wall of the second end of the motor mounting base 10. By providing the filter cover 29, it is possible to prevent impurities from contacting the output shaft of the motor 25 and the axial flow impeller 26. The specific installation structure between the motor mounting base 10 and the filter cover 29 can be a conventional structure, such as using snap-fit ​​or welding. In this embodiment, a threaded connection is used to achieve the fixed installation between the motor mounting base 10 and the filter cover 29. Specifically, the inner side wall of the second end of the motor mounting base 10 is provided with a first internal thread, and the filter cover 29 is provided with a first external thread that mates with the first internal thread. The first internal thread and the first external thread are spirally connected.

[0035] The motor 25 is electrically connected to the controller via a wire 30. Specifically, the side wall of the motor mounting base 10 has a through hole for the wire 25 to pass through.

[0036] The motor mounting base 10 is integrally connected to the base plate 31. The central axis of the first mounting hole 20 is arranged parallel to the plane where the base plate 31 is located. The base plate 31 is provided with a second mounting hole 32 for installation.

[0037] Before use, the motor mounting base 10 is installed on the head of the computerized flat knitting machine via the base plate 31. The first end of the motor mounting base 10 faces the needle bed of the computerized flat knitting machine, and the axis of the first mounting hole 20 is perpendicular to the plane where the needle bed is located. During use, the oil dispenser delivers lubricating oil to the oil spray nozzle 30, which sprays the lubricating oil into the first mounting hole 20. The sprayed atomized lubricating oil mixes with the air. The motor 25 rotates, driving the axial flow fan 26 to rotate. The rotation of the axial flow fan 26 will drive the atomized lubricating oil to rotate after mixing with the air, improving the mixing effect of the atomized oil droplets with the air, and spraying the atomized oil droplets from the oil outlet after mixing with the air.

[0038] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
