Description

Technical Field

[0001] This utility model relates to the technical field of double-sided circular knitting machines, specifically to an oil-proof needle plate for double-sided circular knitting machines. Background Technology

[0002] The upper needle plate of a double-sided circular knitting machine is one of the main components installed on the upper part of the machine for knitting. The upper needle plate has needle grooves for mounting knitting needles, which are connected to the needle hook via needle bars. The design and function of the upper needle plate have a significant impact on the knitting process and the quality of the fabric. A search revealed existing technology (publication number: CN202322958992.6) for an oil-proof upper needle plate on a double-sided circular knitting machine. The article describes that "this utility model adds an oil collection groove at the needle guard groove position to the upper needle plate, and simultaneously uses an air blowing device. The oil collection groove prevents oil lubrication from flowing through the needle guard groove to the needle hook due to centrifugal force, thus acting as an oil cut-off point; at the same time, the air blowing device blows the lubricating oil carried out of the needle groove from the needle bar into the oil collection groove and back into the needle groove. The oil drain hole collects the lubricating oil in the oil collection groove into a waste oil bottle through an external oil pipe, thereby blocking the flow of lubricating oil to the needle hook and preventing contamination of the yarn, eliminating the need for subsequent degreasing processes and reducing costs." However, in this existing technology, excess oil on the knitting needle surface tends to flow outwards due to centrifugal force, making it difficult to ensure that the oil flows down to the oil collection groove of the upper needle plate. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an oil-proof needle plate for a double-sided circular knitting machine is provided to solve the problem that in existing technologies, excess oil on the surface of the knitting needles tends to flow outward due to centrifugal force, making it difficult to ensure that the oil flows down into the oil collection groove of the needle plate.

[0004] To achieve the above objectives, an oil-resistant needle plate for a double-sided circular knitting machine is provided, comprising: a circular knitting machine needle plate body, wherein knitting needles are mounted on the needle groove surface at the upper end of the circular knitting machine needle plate body.

[0005] The upper surface of the needle plate of the large circular knitting machine is provided with an oil drain groove and an annular groove. A support ring plate is engaged in the annular groove. A dividing vertical piece is connected through the inner side of the support ring plate. A limiting base plate is fixed at the lower end of the dividing vertical piece. A spring is connected to the lower end of the limiting base plate through a connecting block. An oil-absorbing ultra-thin pad is supported on the upper surface of the support ring plate and the dividing vertical piece. An oil-absorbing ultra-thin pad is provided with an oil-absorbing fiber layer inside. A first non-woven fabric layer and a second non-woven fabric layer are bonded to the outer side of the oil-absorbing fiber layer.

[0006] Furthermore, an oil storage box is embedded in the inner end face of the needle plate body of the large circular knitting machine through a fixing post, and an oil inlet is opened on the upper end face of the oil storage box.

[0007] Furthermore, the lower end of the oil drain groove is connected to an oil guide groove; and the lower opening of the oil guide groove is located at the upper end of the oil inlet groove, and the annular groove is located at the outer end of the oil drain groove.

[0008] Furthermore, the knitting needle is connected to the needle groove of the needle plate body on the large circular knitting machine through the needle bar, and a needle hook is provided on the side end of the needle bar.

[0009] Furthermore, the dividing vertical piece is limited and connected to the supporting ring plate by a limiting base plate.

[0010] Furthermore, the lower end of the spring is connected to the annular groove surface via a connecting block, and the dividing vertical pieces are distributed circumferentially at the adjacent spacing of the knitting needles.

[0011] Furthermore, the oil-absorbing ultra-thin pad is bonded to the knitting needle, the support ring plate, and the dividing vertical piece through the first non-woven fabric layer and the second non-woven fabric layer, respectively.

[0012] The beneficial effect of this utility model is that the oil-proof needle plate of the double-sided circular knitting machine utilizes a support ring plate and a dividing vertical plate to lay an oil-absorbing ultra-thin pad on the knitting surface. The non-woven fabric layer on the surface of the oil-absorbing ultra-thin pad allows excess oil to enter the oil-absorbing fiber layer for absorption, which facilitates efficient absorption of excess lubricating oil flowing outward along the knitting needles. This prevents excessive lubricating oil from flowing and adhering to the yarn at the knitting needle hook, thereby preventing the occurrence of oil needle phenomenon and improving the oil-proof needle effect of the needle plate of the double-sided circular knitting machine.

[0018] Reference Figures 1 to 4 As shown, this utility model provides an oil-proof needle plate for a double-sided circular knitting machine, comprising: a circular knitting machine needle plate body 1, with knitting needles 2 mounted on the needle groove surface at the upper end of the circular knitting machine needle plate body 1.

[0019] The upper surface of the needle plate body 1 of the large circular knitting machine is provided with an oil drain groove 11 and an annular groove 13. A support ring plate 4 is engaged in the groove of the annular groove 13. A dividing vertical piece 41 is connected through the inner side of the support ring plate 4. A limiting base plate 42 is fixed at the lower end of the dividing vertical piece 41. A spring 43 is connected to the lower end of the limiting base plate 42 through a connecting block 44. An oil-absorbing ultra-thin pad 5 is supported on the upper surface of the support ring plate 4 and the dividing vertical piece 41. An oil-absorbing fiber layer 52 is provided inside the oil-absorbing fiber layer 52. A first non-woven fabric layer 51 and a second non-woven fabric layer 53 are bonded to the outer side of the oil-absorbing fiber layer 52.

[0020] First, the oil-absorbing ultra-thin pad 5 is laid on the support ring plate 4 and the dividing vertical piece 41 at the groove surface of the upper needle plate body 1 of the circular knitting machine. Then, the knitting needle 2 is installed in the needle groove of the upper needle plate body 1 of the circular knitting machine. When the lubricating oil in the groove of the upper needle plate body 1 of the circular knitting machine flows from the needle bar 21 to the needle hook 22 of the knitting needle 2, some of the oil flows into the oil drain groove 11 and is discharged into the oil storage box 3. Some of the oil flows along the knitting needle 2 to the oil-absorbing ultra-thin pad 5. After passing through the first non-woven fabric layer 51 or the second non-woven fabric layer 53 of the oil-absorbing ultra-thin pad 5, it enters the oil-absorbing fiber layer 52 and is absorbed by the oil-absorbing fiber layer 52. This helps to prevent excessive lubricating oil from flowing and adhering to the yarn of the needle hook 22 of the knitting machine, thereby preventing the occurrence of oil needle phenomenon and improving the oil needle prevention effect of the upper needle plate of the double-sided circular knitting machine.

[0021] In this embodiment, an oil storage box 3 is embedded in the inner end face of the upper needle plate body 1 of the circular knitting machine via a fixing post 31. An oil inlet 32 ​​is provided on the upper end face of the oil storage box 3. The lower end of the oil drain trough 11 is connected to an oil guide trough 12; and the lower opening of the oil guide trough 12 is located at the upper end of the oil inlet trough 32. Annular grooves 13 are distributed at the outer end of the oil drain trough 11. The knitting needle 2 is connected to the needle groove of the upper needle plate body 1 of the circular knitting machine via a needle bar 21. A needle hook 22 is provided on the side end of the needle bar 21.

[0022] As a preferred embodiment, the oil collection box 3 facilitates the collection of excess oil flowing out of the oil drain 11, which can then be reused. The oil drain 11 and the annular groove 13 are located between the needle bar 21 and the needle hook 22 of the knitting needle 2, which facilitates the collection and prevents lubricating oil from flowing from the needle bar 21 to the needle hook 22, thus preventing excessive lubricating oil from flowing and adhering to the yarn of the needle hook 22.

[0023] In this embodiment, the dividing vertical piece 41 is limited and connected to the supporting ring plate 4 via the limiting base plate 42. The lower end of the spring 43 is connected to the groove surface of the annular groove 13 via the connecting block 44, and the dividing vertical pieces 41 are distributed circumferentially at the adjacent spacing of the knitting needles 2.

[0024] As a preferred embodiment, the dividing vertical piece 41 facilitates the upward support protrusion of the oil-absorbing ultra-thin pad 5, which is laid flat on the surface of the support ring plate 4, so that the oil-absorbing ultra-thin pad 5 with the upward support protrusion can fit against the side of the knitting needle 2, making it convenient to absorb excess oil flowing from the side of the knitting needle 2.

[0025] In this embodiment, the oil-absorbing ultra-thin pad 5 is attached to the knitting needle 2, the support ring plate 4 and the dividing vertical piece 41 through the first non-woven fabric layer 51 and the second non-woven fabric layer 53 respectively.

[0026] As a preferred embodiment, the first nonwoven fabric layer 51 and the second nonwoven fabric layer 53 facilitate the entry of excess oil into the inner oil-absorbing fiber layer 52, preventing the oil from flowing to the yarn of the needle hook part 22, thus playing a role in preventing oil needles and avoiding oil contamination of the knitted fabric of the double-sided circular knitting machine.

[0027] This utility model of an oil-proof needle plate for a double-sided circular knitting machine effectively solves the problem in the prior art where excess oil on the surface of the knitting needles tends to flow outwards due to centrifugal force, making it difficult to ensure that the oil flows down to the oil collection groove of the upper needle plate. It facilitates efficient absorption of excess lubricating oil flowing outwards along the knitting needles, preventing excessive lubricating oil from flowing and adhering to the yarn at the knitting needle hook, thus preventing the occurrence of oil needle phenomenon and improving the oil-proof needle effect of the upper needle plate for a double-sided circular knitting machine. It is suitable for oil-proof needle plates for double-sided circular knitting machines.
