Description

Technical Field

[0001] The present application relates to the technical field of jacquard, and more specifically, to a piezoelectric jacquard needle plate and a comb jacquard device for a warp knitting machine. Background Art

[0002] A warp knitting machine is a knitting machine that weaves parallel arranged warp yarns into warp knitted fabrics. It mainly consists of parts such as a knitting mechanism, a comb bar traversing mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. Among them, the comb bar traversing mechanism plays a crucial role in the loop forming process. It enables the comb bar to traverse according to the requirements of the fabric structure, pad the warp yarns on the needles, and thus weave a knitted fabric with a certain structure.

[0003] The needle plates on which the piezoelectric ceramic sheets of the existing piezoelectric jacquard needles are installed are either machined with high precision by aluminum alloy CNC or manufactured by injection molding of engineering plastics. First, due to the influence of clamping fixtures, cutting tools, machine processing, and manual operation during the CNC machining of each part, the consistency is very poor, the cost is extremely high, and during use, it is also necessary to clean the oil stains, etc., which affects the high scrap rate and production efficiency during use. Secondly, the thin walls of the engineering plastics are poor in rigidity during forming, and hardware parts need to be used as inserts for injection molding. The force-bearing at places such as buckles is poor, and the stability during use is not as good as that of CNC machined parts. The biggest disadvantages of these two methods are that they are heavy, affect the machine speed, and both have large volumes, poor consistency, and are difficult to process. It is not convenient to make the product into a compact small volume and light weight condition.

[0004] In order to solve the above problems, the present application provides a piezoelectric jacquard needle plate and a comb jacquard device for a warp knitting machine. Utility Model Content

[0023] Embodiment:

[0024] The embodiment of the present application discloses a piezoelectric jacquard needle plate and a comb jacquard device for a warp knitting machine. Please refer to Figures 1 - 6 , including a main frame mechanism 1. On one side of the top of the main frame mechanism 1, there is a front tooth head 2. On the side of the top of the main frame mechanism 1 far from the front tooth head 2, there is a plastic structural member 3. The top of the main frame mechanism 1 is provided with an electro-ceramic conductive socket 4 penetrating between the front tooth head 2 and the plastic structural member 3 relatively. The material of the front tooth head 2 is a plastic component. This component of the front tooth head 2 is located on one side of the top of the main frame mechanism 1 and is made of plastic material. The selection of the plastic component not only reduces the overall weight but also may improve the wear resistance and cost-effectiveness, and is suitable for a fine and complex warp knitting operation environment. The plastic structural member 3 is located on the other side of the top of the main frame mechanism 1 opposite to the front tooth head 2 and is also made of plastic material, further reflecting the design idea of lightweight and cost optimization. The plastic structural member 3 may carry functions such as support, fixation, or other auxiliary functions to ensure the stability and reliability of the entire device. The electro-ceramic conductive socket 4 is located at the top of the main frame mechanism 1 between the front tooth head 2 and the plastic structural member 3 and is installed through penetration. The introduction of the electro-ceramic conductive socket 4 may be used to connect and transmit piezoelectric signals to control the precise movement of the jacquard needle plate and realize the weaving of complex jacquard patterns. The material selection of the electro-ceramic may be based on its excellent electrical conductivity, stability, and temperature resistance to meet the requirements of high-speed and high-precision warp knitting operations.

[0025] The main frame mechanism 1 includes connecting bars 101. The number of the connecting bars 101 is two. On one side between the opposite connecting bars 101, there is a reinforcing rib 102. On the other side between the opposite connecting bars 101, there is a connecting plate 103. At both ends of the reinforcing rib 102 close to the connecting bar 101, there are reinforcing rib buckles 104. On both sides of the connecting plate 103 close to the connecting bar 101, there are symmetric connecting plate buckles 105. The connecting bar 101 is a stamping part made of high-strength stainless steel bar. The reinforcing rib 102 is a stamping part of stainless steel with two-hole screw positions. The connecting plate 103 is a stamping part made of stainless steel plate. The connecting bar 101 serves as the main load-bearing and connecting component of the main frame mechanism 1, and two stamping parts made of high-strength stainless steel bars are adopted for the connecting bar 101. This design not only ensures the stability of the frame, but also improves the overall corrosion resistance and durability through the selection of stainless steel material, making it suitable for use in complex and changeable industrial environments. The reinforcing rib 102 is a specially designed stamping part of stainless steel with two-hole screw positions to further enhance the connection strength between the connecting bars 101 and improve the rigidity of the overall frame. These reinforcing ribs are cleverly arranged between the opposite connecting bars 101, and there are reinforcing rib buckles 104 at both ends of the reinforcing rib close to the connecting bar 101, so as to be tightly fixed to the connecting bar and other components, effectively resisting external force impact and deformation. The connecting plate 103 is located on the other side between the opposite connecting bars 101. The connecting plate 103 is made of a stamping part of stainless steel plate and has sufficient strength and stiffness to support the installation and connection of other components. On both sides of the connecting plate 103 close to the connecting bar 101, there are symmetric connecting plate buckles 105. These buckle designs facilitate quick and accurate connection with other components, and at the same time improve the stability and reliability of the connection.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
