DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 and Figure 2As shown, an oil-blocking mechanism 3 of a large circular knitting machine comprises a base 1, a frame 2 is fixed on the upper end of the base 1, a pulling and winding mechanism 3 is fixed on the upper end of the base 1, an oil-blocking assembly 4 is connected to the inner wall of the frame 2, the pulling and winding mechanism 3 is located on the inner side of the oil-blocking assembly 4, the oil-blocking assembly 4 comprises a plurality of brackets 5, a plurality of oil guide plates 6 and a plurality of oil collecting grooves 7, each bracket 5 is respectively connected to the inner end surface of each side frame 2 through a spring 16, each oil guide plate 6 is respectively connected between two adjacent brackets 5, each oil guide plate 6 is connected to each bracket 5 to form a truncated cone structure which is narrow on the top and wide on the bottom, each oil collecting groove 7 is respectively connected to the bottom end of the corresponding oil guide plate 6, and the left and right ends of the oil collecting groove 7 are respectively connected to the side wall of the bracket 5 on the corresponding side, the lubricating oil dripping from the needle cylinder of the large circular knitting machine drips onto the oil guide plate 6, and then flows along the surface of the oil guide plate 6 to be collected in the oil collecting groove 7.

[0018] See also Figure 2 and Figure 3 As shown, the bracket 5 is composed of an oblique frame 8 and a cross frame 9. The oblique frame 8 is fixedly installed on the inner side of the top end of the cross frame 9. The left and right side walls of the oblique frame 8 are provided with sliding grooves 10 along the length direction, and the bottom of the sliding groove 10 extends through to the bottom surface of the cross frame 9. The left and right ends of the oil guide plate 6 are provided with clamping plates 11 adapted to the sliding grooves 10. The left and right ends of the oil collecting trough 7 are connected to the cross frame 9. The left and right end surfaces of the cross frame 9 are horizontally provided with clamping grooves 12. The left and right ends of the oil collecting trough 7 are provided with clamping blocks 13 adapted to the clamping grooves 12.

[0019] See also Figure 3 As shown, a rubber pad 14 is provided at the bottom of the oil guide plate 6, and the inner side of the top of the oil collecting groove 7 is depressed downward to form a groove 15. After the oil guide plate 6 and the oil collecting groove 7 are connected, the rubber pad 14 abuts against the groove 15. Through this structural abutment, the gap at the connection between the oil guide plate 6 and the oil collecting groove 7 can be reduced to prevent oil from seeping out. At the same time, the inner side of the oil collecting groove 7 is supported on the bottom of the oil guide plate 6 to prevent the oil guide plate 6 from sliding down under its own gravity.

[0020] The working principle of this embodiment is as follows:

[0021] The lubricating oil dripping from the needle cylinder of the large circular knitting machine drips onto the oil guide plate 6, and then flows along the surface of the oil guide plate 6 to the oil collecting tank 7 for collection. Since the bracket 5 is connected to the side frame 2 by a spring 16, the entire oil baffle assembly 4 is movable. When the large circular knitting machine is working, it will inevitably vibrate due to the high-speed rotation of the needle disk. The vibration will drive the entire oil baffle assembly 4 to shake slightly through the spring 16, thereby helping the lubricating oil on the oil guide plate 6 to flow into the oil collecting tank 7 more quickly and smoothly; when too much oil is adhered to the side of the oil guide plate 6 or there are too many oil stains in the oil collecting tank 7, which affects the use effect and needs to be cleaned, first put the barrel under the oil collecting tank 7, then pull the oil collecting tank 7 out of the card slot 12 horizontally, pour the oil stains in it into the barrel, and then tilt the oil guide plate 6 out of the slide slot 10, so that it can be taken away for cleaning. After cleaning, the oil guide plate 6 and the oil collecting tank 7 are successively inserted into the bracket 5 for continued use.

[0022] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
