Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting equipment, specifically to an oil return mechanism for an upper sinker plate. Background Technology
[0002] like Figure 1 As shown, existing circular knitting machines (or circular knitting weft machines) include an upper cutting disc assembly a, support legs b, and an upper sinker c. An oil nozzle (not shown in the figure) is mounted on the mounting part a1 of the upper cutting disc assembly a. During operation, the oil nozzle (not shown in the figure) adds lubricating oil to the upper sinker c below it to ensure smooth sliding. However, existing circular knitting machines lack a lubricating oil return mechanism for the upper sinker c, causing lubricating oil to flow freely across the surface of the machine's components, making lubricating oil recycling difficult. Over time, this can easily affect the normal operation of the equipment, pollute the factory floor and air, and affect the appearance of the circular knitting machine. Figure 1 As shown in the example, the lubricating oil will flow roughly along the bottom of the upper cutting disc assembly a to the upper connecting surface of the support foot b, and drip from the edge of the support foot b to the saddle ring d or the small frustum ring e, and then flow from the saddle ring 2 or the small frustum ring d to the large disc f, i.e., path Q1, path Q2. Summary of the Invention
[0003] The purpose of this invention is to provide an oil return mechanism for an upper settling plate, which aims to overcome the aforementioned problems existing in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An oil return mechanism for an upper settling plate includes an upper cutting disc assembly, a saddle ring, a large gear ring, and a large disc. The lower end face of the upper cutting disc assembly is provided with a first annular oil-stopping groove, and the upper end face of the saddle ring is provided with a first annular oil-collecting groove, with the first annular oil-collecting groove located below the first annular oil-stopping groove. The first annular oil-collecting groove has at least one first oil leakage hole. The large gear ring has a second annular oil-collecting groove, with the second annular oil-collecting groove located below the first oil leakage hole. The second annular oil-collecting groove has at least one second oil leakage hole, and the large disc has a third annular oil-collecting groove, with the third annular oil-collecting groove located below the second oil leakage hole. The third annular oil-collecting groove has a third oil leakage hole.
[0006] Furthermore, an annular boss is formed on the upper surface of the saddle ring outside the first annular oil collecting groove, and the annular boss has multiple mounting holes for connecting the small frustum ring.
[0007] Furthermore, the inner end of the aforementioned first annular oil collecting groove is provided with a plurality of the aforementioned first oil leakage holes evenly distributed in an annular pattern.
[0008] Furthermore, the first annular oil collecting groove is provided with a plurality of fan-shaped protrusions for mounting the saddle evenly distributed in an annular shape, and the gap between two adjacent fan-shaped protrusions forms an oil passage, and at least one oil passage has the first oil leakage hole on its inner end.
[0009] Furthermore, the lower end face of the aforementioned saddle ring is provided with an annular protrusion, and the annular protrusion is located outside the first oil leakage hole.
[0010] Furthermore, the aforementioned annular protrusion is also provided with a second annular oil-stopping groove.
[0011] Furthermore, the lower end face of the second oil leakage hole is provided with an extension that extends into the interior of the third annular oil collection groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Firstly, the oil return mechanism disclosed in this utility model mainly consists of a first annular oil-stopping groove, a first annular oil-collecting groove, a first oil-leaking hole, a second annular oil-collecting groove, a second oil-leaking hole, a third annular oil-collecting groove, and a third oil-leaking hole. It guides and collects the lubricating oil from the upper settling plate, preventing the lubricating oil from flowing freely. The entire oil return mechanism requires minimal modification to the original assembly structure, has low cost, a reasonable design, and good lubricating oil recovery effect.
[0014] Secondly, in this invention, an annular boss is formed on the outer side of the first annular oil collecting groove on the upper end surface of the saddle ring. This annular boss has multiple mounting holes for connecting the small truncated ring. The annular boss can prevent lubricating oil from flowing outward; at the same time, setting the mounting holes on the annular boss can prevent lubricating oil from dripping from the gap between the screw and the mounting hole, further optimizing the recycling effect.
[0015] Thirdly, in this utility model, the first oil leakage hole is located at the inner end of the first annular oil collecting groove, so that while avoiding the saddle, the lubricating oil can drip smoothly from the first oil leakage hole to the second annular oil collecting groove. The multiple first oil leakage holes are evenly distributed in an annular shape to accelerate the dripping speed of the lubricating oil and prevent the lubricating oil from overflowing from the first annular oil collecting groove.

[0022] To facilitate understanding, a brief explanation of the relevant conversion structure of the large circular loom will be given first. In terms of orientation, the central axis of the large circular loom is considered the inside, and the edge is considered the outside. In the annular structure, the side closer to the central axis is the inner end, and the side farther from the central axis is the outer end.
[0023] like Figure 2 As shown, the large circular knitting machine includes an upper cutting disc assembly 1, a saddle ring 2, a large gear ring 3, a large disc 4, a small frustum ring 5, support feet 6, saddles 7, and upper sinkers 8. The large disc 4 is rotatably mounted with the large gear ring 3, and the small frustum ring 5 is fixedly mounted thereon. The upper cutting disc assembly 1 is fixedly supported by multiple support feet 6. The small frustum ring 5 is fixedly mounted with the saddle ring 2, and multiple saddles 7 are evenly distributed in a ring around the saddle ring 2. Multiple upper sinkers 8 are also slidably mounted on the large disc 4 via brackets. During operation, an oil nozzle (not shown in the figure) installed on the mounting part 10 of the upper cutting disc assembly 1 adds lubricating oil to the slide rails of the upper sinkers 8 to ensure smooth sliding of the upper sinkers 8.
[0024] like Figure 2 As shown, this utility model discloses an oil return mechanism for an upper settling plate. The oil return mechanism mainly involves the assembly parts of a large circular kiln, including an upper cutting disc assembly 1, a saddle ring 2, a large gear ring 3, and a large disc 4.
[0025] like Figure 2 As shown, the lower end face of the upper cutting disc assembly 1 is provided with a first annular oil-stop groove 11. Specifically, the outer end of the upper cutting disc assembly 1 is fixedly installed on the upper end of the support leg 6 by means of screws or the like, while the first annular oil-stop groove 11 is located on the inner side of the support leg 6 and is spaced apart from the support leg 6.

[0030] The number of first oil leakage holes 22 includes, but is not limited to, six. Taking 86 saddles 6 as an example, 86 fan-shaped protrusions 211 are evenly distributed in a ring on the bottom surface of the first annular oil collecting groove 21, forming 86 oil passages 210.
