After the founding of the People's Republic of China, China widely introduced and localized production and use of the trolley.

[0003] The trolley is still used in a small range at present, but compared with the early style, there is no obvious technical progress.

DETAILED DESCRIPTION

[0029] The application will be further described below based on the preferred embodiments and with reference to the drawings.

[0030] The words in the present specification are used for describing the embodiments of the present application but are not intended to limit the present application. Unless explicitly defined and limited otherwise, if the terms "set", "connected", "connection" appear, they should be interpreted broadly, for example, can be fixed connection, can be detachable connection, or integrally connected; can be mechanical connection, can be directly connected, can be indirectly connected through intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood specifically.

[0031] In addition, in the description in the embodiments of the present application, various components on the drawing are exaggerated or reduced for the convenience of understanding, but this practice is not intended to limit the protection scope of the present application.

[0032] The old-fashioned trolley is a traditional device for weaving jacquard fabric using a special weaving 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 weave a jacquard fabric of one pattern, if multiple patterns are needed, multiple flower butterflies of 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.

[0033] Need to be particularly pointed out, the patent disclosure No. CN1055778A old trolley embossed plate has been improved, the application through the change of embossing wheel instead of the original countless embossed plate, to facilitate the sample weaving process, increase the change of knitted pattern, to save raw materials and sample time. From the description of the application, the main structure of the change of the embossing wheel is: there is a core and a needle plate on the core, the core is also sleeved with a flower disc with the same depth and width of the groove, the groove of the flower disc is inserted with a key, the right part of the flower disc is sleeved with a pressing plate and a pressing nut. That is, the application only improves the old trolley embossed plate, and the arrangement and arrangement of the flower disc and the key need to be determined according to the pattern and arrangement sequence of the knitted fabric, the efficiency is limited, and the experience and technical requirements of the operator are still high.

[0034] However, with the progress of the times and the diversification of market demand, the limitations of the old trolley are increasingly prominent. Its low degree of automation, low efficiency and rough design and manufacture have been difficult to meet the urgent needs of the current market for diversified products. However, the fabrics produced by the old trolley still occupy a certain share in the market due to their unique process and irreplaceability, which ensures that the old trolley will not be completely eliminated.

[0035] In the face of this situation, it is particularly urgent to upgrade and optimize the old trolley. However, the existing knitting trolley in the current market, even the latest model, has not made significant progress in technology compared with the early Tom King knitting machine. This shows that the upgrading of the old trolley is not only necessary, but also challenging, and needs to break through the limitations of existing technology to achieve real technological innovation.

[0036] In summary, although the old trolley faces the disadvantages of low degree of automation, low efficiency and rough design, the fabrics produced by it have 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.

[0037] Based on the irreplaceability of the fabrics produced by the old trolley, the application applies the jacquard device 1 to the upgrading and optimization of the old trolley.

On the one hand, the climbing height of the needle 11 is not limited by the middle spring 12, so as to complete the knitting of the fabric with longer length, so as to greatly enrich the knitting effect of the fabric; on the other hand, the resistance, pressure and other adverse effects of the jacquard device 1 in the needle groove are small, so as to greatly improve the production efficiency and the fabric production capacity; on the other hand, when one of the needle 11 and the middle spring 12 is damaged, it can be replaced alone, so as to be convenient for maintenance and use.
