Description

Technical Field

[0001] This utility model relates to the technical field of jacquard machine components, and in particular to a jacquard machine knife-lifting lever device. Background Technology

[0002] The jacquard loom, as a textile tool, is an important invention of ancient China. Ordinary looms can only weave plain weave fabrics, while only jacquard looms can weave fabrics with complex patterns.

[0003] Traditionally, in jacquard looms, the weft feed side knife lifting assembly is used to drive the lifting knives. The weft feed side knife lifting assembly is made of cast steel (iron) and includes a lifting knife connecting plate and a tie rod integrally formed therewith. There are several sets of tie rods, and each set of tie rods connects the lifting knives to the lifting knife connecting plate. When the weft feed side knife lifting assembly is driven by the drive unit, it can synchronously drive each set of lifting knives to move synchronously through the tie rods.

[0004] However, the overall weight of the weft feed side lifting knife mounting component is large. When the processing cycle is too long, the entire machine is under heavy load. Under the working conditions of large needle count and large pattern, the wear between the lifting knife and the pull rod is large. Moreover, each set of lifting knives and the lifting knife connecting plate are integrally formed. After the pull rod is severely worn, the whole machine needs to be replaced, which has low applicability. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a jacquard machine knife-lifting rod device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a jacquard machine knife-lifting lever device, comprising a knife-lifting lever connecting a knife-lifting connecting plate and a knife-lifting lever, wherein the knife-lifting lever is provided in several groups, the knife-lifting lever comprising a lever body and fixed sleeves disposed at its two ends, one group of fixed sleeves being rotatably connected to the knife-lifting connecting plate, and another group of fixed sleeves being rotatably connected to the knife-lifting lever, wherein a knife-lifting connecting piece is provided on the knife-lifting lever and is rotatably connected to the fixed sleeve.

[0007] Preferably, the knife-lifting rod is made of carbon fiber nylon.

[0008] Preferably, the fixing sleeve and the tie rod are integrally injection molded.

[0009] Preferably, the fixed sleeve is fitted with a sliding bearing.

[0010] Preferably, a bushing is provided inside the sliding bearing.

[0011] Preferably, the bushing is a self-lubricating bearing bushing.

[0012] The beneficial effects of this utility model are as follows: By using carbon fiber nylon for the knife lifting rod, its weight can be reduced by several times compared with the prior art. This not only directly reduces the weight of the knife lifting rod itself, but also significantly reduces the overall weight of the weft feeding side knife lifting installation component, thereby reducing the overall machine operating load and energy consumption. At the same time, a sliding bearing is embedded in the fixed sleeve in the knife lifting rod, and a bushing is set in the sliding bearing, which greatly reduces the coefficient of friction and reduces the direct wear between the knife lifting rod and the knife lifting connecting plate and the knife lifting connection, thus improving the overall wear resistance and service life.

[0015] The following description is only a preferred embodiment of the present utility model. The scope of protection is not limited to this embodiment. All technical solutions that fall within the scope of the present utility model should be protected by the present utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present utility model should also be considered within the scope of protection of the present utility model.

[0016] It should be noted that in this document, relational terms such as first and second, or "connecting plate one, connecting plate two," are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0017] The directional terms mentioned in this embodiment, such as "up," "down," "left," and "right," are merely used to help those skilled in the art understand the relationships between various features or parts in conjunction with the accompanying drawings.

[0018] In this embodiment, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figures 1 to 3 As shown, a jacquard machine knife-lifting lever device includes a knife-lifting lever connecting a knife-lifting connecting plate 1 and a knife-lifting 2. The knife-lifting lever is detachably connected to both the knife-lifting connecting plate 1 and the knife-lifting 2. Several sets of knife-lifting levers are arranged sequentially along the length of the knife-lifting connecting plate 1. Each knife-lifting lever includes a lever body 301 and fixing sleeves 302 disposed at its upper and lower ends. In this embodiment, the two sets of fixing sleeves 302 and the lever body 301 are integrally injection molded and made of carbon fiber nylon. One end of the fixing sleeve 302 on the lever body 301 is rotatably connected to the knife-lifting connecting plate 1, and the other end of the fixing sleeve 302 is connected to the upper side of the knife-lifting 2. Specifically, a rotating shaft (not shown in the figure) is provided on the knife-lifting connecting plate 1. The rotating shaft passes through the lever body 301 and faces the knife-lifting connecting plate 1. The middle of the fixed sleeve 302 at one end of the connecting plate 1 allows it to rotate around the central axis of the rotating shaft. The fixed sleeve 302 at the end of the pull rod body 301 facing the lifting knife 2 is connected to the lifting knife 2 through the lifting knife 2 connector. In this embodiment, the lifting knife 2 connector is fixed on the lifting knife 2. A rotating shaft is also provided on the lifting knife 2 connector. The rotating shaft passes through the middle of the fixed sleeve 302 at the end of the pull rod body 301 facing the lifting knife 2. Oil sliding bearings 5 ​​are embedded inside both sets of fixed sleeves 302. A bushing 6 is provided inside the sliding bearing 5. The outer diameter of the end of the rotating shaft located inside the fixed sleeve 302 is smaller than that of the bushing 6. Therefore, the bushing 6 is sleeved on the outer wall of the rotating shaft. The bushing 6 is a self-lubricating bearing bushing 6. The purpose is to reduce the problem of large friction between the rotating shaft and the fixed sleeve 302 during movement.

[0020] Its layout design involves sequentially arranging several sets of lifting rod components along the length of the lifting rod connecting plate 1. One end of each set of lifting rod components is rotatably connected to the lifting rod connecting plate 1 via a rotating shaft, and the other end is rotatably connected to the lifting knife 2. This facilitates personnel in replacing the rods, allowing for the replacement of rods of different specifications according to actual requirements, thus improving the applicability of the entire machine.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
