[0004] The aforementioned riveting on the tail of the needle plate is an effective measure to improve the tight fit between the insert and the needle plate, and various technical information related to the needle plate riveting device can be found in the published Chinese patent documents, such as the "a kind of riveting device" recommended by CN203636298U. Needle plate device", this patent scheme can objectively embody the advantages recorded in paragraph 0017 of its specification that it is "beneficial to replacing time-consuming and laborious manual work, high It is not difficult to find that there are the following defects: one, due to the inevitable deflection of the needle plate itself, and the inevitable errors in the process of processing the needle plate and the production process of the insert, according to the patent specification No. 00027 There is a certain degree of blindness in the riveting of the tail of the needle plate, so it is difficult or even impossible to make all the inserts on the needle plate obtain the same effect of tightly fitting with the needle plate
Because when the pressure wheel of the riveting needle plate device (that is, the rolling cutter head, the same below) corresponds to the deflection part of the needle plate (arc valley, that is, the concave part), the pressure wheel appears to be in contact with the tail of the needle plate but not in contact. , so because the pressure wheel cannot effectively rivet the tail of the needle plate at this deflection position, the effect of the tight fit between the insertion piece and the needle plate corresponding to this position cannot be reflected. When the out position corresponds, there is a risk of damage to the needle plate due to the excessive (excessive) riveting pressure of the pressure roller on the position.
It can be seen from this that only when the riveting pressure exerted by the pressure roller on the tail of the needle plate is always the same, then it can be guaranteed that all the inserts on the needle plate and the needle plate are closely matched to the same degree, and there will be no tightness or looseness or tightness and looseness. Second, due to the use of hydraulic presses, on the one hand, the structure is complicated, and on the other hand, it is unfavorable to save space due to the large volume

The needle plate riveting device comprises a device base, a set of needle plate positioning mechanisms, a rolling cutterhead moving frame driving mechanism, a rolling cutterhead moving frame, a rolling cutterhead driving mechanism and a rolling cutterhead pressure sensor, wherein a needle plate supporting platform and a rolling operation platform are arranged on the upper part of the device base; the needle plate positioning mechanisms are fixed to the front side of the device base and correspond to the upper part of the needle plate supporting platform; the rolling cutterhead moving frame driving mechanism is arranged on the rolling operation platform; the rolling cutterhead moving frame is arranged on the rolling operation platformand matched with the rolling cutterhead moving frame driving mechanism; the rolling cutterhead driving mechanism is arranged on the rolling cutterhead moving frame, and the position, corresponding tothe rear side of the needle plate supporting platform, of the rolling cutterhead is arranged on the rolling cutterhead driving mechanism; and the rolling cutterhead pressure sensor is arranged on therolling cutterhead driving mechanism, an electrical controller is arranged on the front side of the device base, and the rolling cutterhead moving frame driving mechanism, the rolling cutterhead driving mechanism, the rolling cutterhead pressure sensor and the set of needle plate positioning mechanisms are in electrical control connection with the electrical controller. The same close fit effect of plug pieces arranged on the same needle plate and the needle plate is guaranteed; and the structure is concise, and the size is small.
Description
technical field [0001] The invention belongs to the technical field of auxiliary facilities for knitting machine processing, and in particular relates to a needle plate riveting device. Background technique [0002] The aforementioned needle plate riveting device can also be called a needle plate rolling device or a needle plate rolling device (hereinafter the same), which is used to plastically deform the material at the end of the needle plate to form a local riveting with the insert, that is, to make the insert The blade fits closely with the needle plate. [0003] As known in the industry, the shape of the needle plate (that is, what is commonly called "needle plate body" or "needle bed body", hereinafter the same) is usually a rectangular parallelepiped and is made of carbon steel. There are many regular and equal-spaced straight grooves on the plane of the needle plate (that is, "insert slots"), and the inserts are inlaid (that is, inserted) in these straight grooves....
