[0001] The utility model relates to the technical field of computerized flat knitting machines, in particular to a needle plate of a textile machine. Background Art
[0002] Computer flat knitting machine is a machine commonly used in the textile industry, and the needle plate is an extremely important component in the computer flat knitting machine. After searching, a Chinese patent with the authorization announcement number of CN211079509U discloses an improved needle plate, including a needle plate and an insert, the side of the needle plate is fixedly connected with a fixed plate, the upper surface of the fixed plate is threadedly connected with a fixing bolt, the upper surface of the needle plate is provided with a mounting hole, one end of the upper surface of the needle plate is threadedly connected with a card plate through a bolt, the upper surface of the needle plate is provided with a slot, the inner bottom wall of the slot is fixedly connected with a card block, the side of the card block is plugged with an insert, and the front of the needle plate is provided with a threaded hole. The improved needle plate, through the setting of the insert, the slot and the card block, the insert is plugged into the card block of the inner bottom wall of the slot, when the needle plate is used for a long time, the insert will be worn, and the user only needs to take out the worn insert for replacement, and when the number of needles needs to be changed, taking out the extra insert can provide great convenience for the user, and also saves costs and prolongs the service life of the needle plate.
[0003] Although the needle plate in this solution replaces the traditional integrated structure and has the function of detachable and replaceable inserts, since the inserts are still fixed after replacement, the slot depth between each insert can only remain unchanged.

[0041] Specifically, the working principle of the needle plate of the textile machine is as follows: when in use, first check whether the structure of the needle plate is intact. After ensuring that the structure is intact, put it into assembly and use. By using fasteners to insert the limiting holes 4002, the needle plate is fixed, and by providing a step layer inside the limiting holes 4002, the fasteners inserted inside the limiting holes 4002 can be fixed, thereby ensuring the flatness of the top surface of the fixing plate 4001. At the same time, the connection with the pressure pad 4003 is beneficial to supporting the fixing plate 4001, thereby improving the stability of the fixation of the needle plate. Among them, by pinching the knob 6001 and twisting it, it drives the driving gear 6002 to rotate, and cooperates with multiple driven gears 6003. The meshing relationship with the driving gear 6002 allows multiple driven gears 6003 to drive the lead screw 6004 to rotate respectively, and then through the threaded connection relationship between the lead screw 6004 and the threaded hole 2004, the cross plate 2001 can be raised and lowered inside the slot until the plug 2002 is lifted to a specified height position, thereby enabling the wire groove formed between the spacing groove 2003 and the partition bar 3002 to be adjusted in depth, thereby guiding the wiring harness on the needle plate, and through the connection between the side plate 3001 and the partition bar 3002, it is engaged in the interior of the spacing groove 2003, thereby facilitating the side support of each plug 200 to avoid tilting due to pressure, thereby ensuring the stability of the internal space size of the spacing groove 2003.
[0042] It should be noted that the depth dimension of the spacing groove 2003 is large enough, and the depth dimension of the plug 2002 changes during the lifting and lowering movement, and the upper limit value reached can be fully applicable to any wiring harness, so it will not be described in detail.
[0043] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
