Description

Technical Field

[0001] This application relates to the field of knitting machine accessories, specifically to a jacquard device for an electronic trolley. Background Technology

[0002] The knitting machine, also known as a trolley or knitting trolley, originated from the Thomson knitting machine, first invented in England in 1847 and later improved by the Thomson brothers in the United States. It uses an electric motor to drive two symmetrical needle cylinders for knitting. my country widely introduced and localized its production and use of this machine after the founding of the People's Republic of China.

[0003] Knitting machines are still used to a limited extent, but there has been no significant technological advancement compared to earlier models. Knitting machines rely solely on manual arrangement of limited fabric textures or weave patterns for purely mechanical weaving, severely limiting their application and demanding high levels of experience and skill from operators. Furthermore, their low level of automation, low efficiency, and crude design and manufacturing have gradually marginalized them from the knitting industry.

[0004] However, contrary to the aforementioned trend, the textile and apparel industry's demand for diversified products means that fabrics made using traditional textile sewing machines still have a market. In traditional sewing machines, the core component that completes the weaving process is the pattern press. The pattern on the pattern press, determined by the fixed number and depth of its grooves, determines the fabric's pattern, and the yarn length for weaving is also fixed. Therefore, upgrading existing sewing machines requires first upgrading this core textile component—the pattern press—and then, based on this upgrade, evolving into an electronic sewing machine.

[0005] Based on the above problems, this application applies a jacquard device to an electronic trolley to perform digital jacquard pattern design and weaving while adapting to the weaving of fabrics with different yarn lengths. Utility Model Content

[0006] The purpose of this application is to provide a method for applying a jacquard device to an electronic trolley to perform digital jacquard pattern design and weaving while adapting to the weaving of fabrics with different yarn lengths.

[0007] The embodiments of this application can be implemented through the following technical solutions:

[0008] A jacquard device for an electronic trolley can be used with a knitting triangle and a needle cylinder. The needle cylinder has a needle groove for accommodating the jacquard device, and the jacquard device can reciprocate within the needle groove.

[0009] The jacquard device includes, from top to bottom, a knitting needle, a center bar, and a jacquard plate, with the bottom end of the knitting needle contacting the top end of the center bar.

[0010] The knitting cam is provided with a first needle path matched with the needle and a second needle path matched with the middle spring, and the needle cylinder is provided with an annular groove matched with the jacquard piece, and the annular groove is clamped with the jacquard piece.

[0011] Further, the needle comprises a first needle foot on the side of the needle away from the needle cylinder, and the first needle foot is in abutment with the first needle path.

[0012] Further, the middle spring comprises a second needle foot on the side of the middle spring away from the needle cylinder, and the second needle foot is in abutment with the second needle path.

[0013] Further, the jacquard piece comprises a third needle foot on the side of the jacquard piece facing the needle cylinder, and the third needle foot is clamped with the annular groove.

[0014] Further, the knitting cam further comprises a cam body, and the inner side of the cam body is in abutment with the outer side of the needle cylinder, and the first needle path and the second needle path are grooves provided on the side of the cam body facing the needle cylinder.

[0015] Further, the jacquard device is made of flat material.

[0016] The embodiment of the present application provides a jacquard device of an electronic trolley.

[0017] The present application applies the jacquard device to the electronic trolley, upgrades and optimizes the flower pressure plate which is the core textile element of the old trolley, realizes digital jacquard pattern design and weaving, and lays an important foundation for upgrading and optimizing the old trolley to the electronic trolley.

[0018] The bottom end of the needle of the jacquard device in the present application can contact the top end of the middle spring. On the one hand, the needle and the middle spring cooperate with each other, the needle is separated from the middle spring in the lifting stage, and is supported by the middle spring after falling, so that the climbing height of the needle is not affected by the middle spring, and the weaving of the yarn with a longer length is completed, so that the weaving effect of the fabric is greatly enriched. On the other hand, the resistance, pressure and other adverse effects of the jacquard device in the needle groove are small, the production efficiency can be greatly improved, and the fabric production capacity can be improved.

DETAILED DESCRIPTION

[0028] Hereinafter, the present application is further explained based on the preferred embodiments and with reference to the accompanying drawings.

[0029] The terms in the specification are used for describing the embodiments of the present application, but are not intended to limit the present application. Unless otherwise explicitly defined and limited, if the terms "arranged", "connected", "linked" appear, they should be broadly understood, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be specifically understood.

[0030] In addition, in the description in the embodiments of the present application, various components on the drawing are enlarged or reduced for the convenience of understanding, but this practice is not intended to limit the protection scope of the present application.

[0031] The old-fashioned trolley is a traditional device for knitting jacquard fabric using a specific knitting tool, a flower pressing plate composed of a core, a pressing needle steel plate and a flower butterfly. In this mechanism, the flower butterfly plays a key role, which has a fixed number of slots and a deep and shallow slot arrangement, which determines the pattern of the fabric. Since a single flower butterfly can only knit one kind of jacquard fabric, if multiple patterns are needed, multiple flower butterflies with different shapes must be manually made. In this process, not only does the operator require superb experience and technology, but also the process of making different shapes of flower butterflies is time-consuming and laborious, and the design is often rough.

[0032] It should be particularly pointed out that the patent with publication number CN1055778A improves the flower pressing plate of the old-fashioned trolley. The application replaces the original countless pressing plates with a changeable jacquard wheel to facilitate the sample making and weaving process, increase the change of knitted patterns and designs, and save raw materials and sample making time. From the description of the application, the main structure of the changeable jacquard wheel is: there is a core and a pressing needle steel plate sleeved on the core, the core is also sleeved with a flower disc with uniformly distributed slots of the same depth and width, the slots of the flower disc are inserted with keys, and the right part of the flower disc is sleeved with a pressing plate and a pressing nut for pressing the keys. That is, the present application only improves the flower pressing plate part of the old-fashioned trolley, and the arrangement and arrangement of the flower disc and the key need to be determined according to the pattern and arrangement sequence to be knitted. The efficiency is limited, and the experience and technical requirements of the operator are still high.

[0033] However, with the progress of the times and the diversification of market demand, the limitations of the old-fashioned trolley are increasingly prominent. Its low degree of automation, low efficiency and rough design and manufacture have made it difficult to meet the urgent needs of the current market for diversified products. Despite this, the fabrics produced by the old-fashioned trolley still occupy a certain share in the market due to their unique process and irreplaceability, which ensures that the old-fashioned trolley will not be completely eliminated.

[0034] In the face of this situation, upgrading and optimizing the old-fashioned trolley is particularly urgent. However, the current market exists knitting trolley, even if the latest model, compared with the early Tom King knitting machine, there is no significant progress in the technical level. This shows that the upgrade of the old-fashioned trolley is not only necessary, but also challenging, and needs to break through the limitations of existing technology to achieve real technological innovation.

[0035] In summary, the old-fashioned trolley, although it has low automation, low efficiency and rough design, the fabric produced by it has irreplaceable market value. Therefore, upgrading and optimizing it not only adapts to market demand, but also maintains and improves its competitiveness in the textile industry.
