Latch needle bed assembly of double-needle-bed tricot machine

Abstract

The invention discloses a latch needle bed assembly of a double-needle-bed tricot machine. The latch needle bed assembly comprises a needle bed base, a needle slot plate, latch needles, a needle pressing plate and a punching plate, wherein a plurality of needle slots which are matched with the latch needles are arranged on the needle slot plate in the length direction; the punching plate is used for compacting the latch needles in the needle slots of the needle slot plate by the needle pressing plate; the needle slot plate and the base of a needle bed are of a split structure; in addition, the needle slot plate consists of a plurality of independent small-section needle slot plates, wherein each small section of needle slot plate is respectively fixedly connected with the base of the needle bed; and the latch needle bed assembly further comprises a positioning and adjusting device which is used for adjusting a latch needle interval between connection parts of every two adjacent small-section needle slot plates and positioning the every two adjacent needle slot plates to each other. The length of each small section of needle slot plate is preferably 50-350mm. According to the latch needle assembly, not only the latch needles can be replaced singly, but also the accumulative error generated by needle slot processing is eliminated, and the latch needle interval can be adjusted; and the latch needle assembly disclosed by the invention has the advantages of convenience for manufacturing and low production cost.

Description

technical field [0001] The invention relates to a knitting mechanism of a double needle bed warp knitting machine, in particular to a latch needle bed assembly in the double needle bed warp knitting mechanism. Background technique [0002] The latch needle bed assembly in the knitting mechanism of the existing double needle bed warp knitting machine usually adopts the following two structures: one is the needle block type, which is composed of a needle bed base and a large number of needle blocks, and each needle The width of the block is generally 25.4 mm, and several latch needles are bonded and fixed on each needle block by adhesive, and each needle block is fixed on the base of the needle bed by bolts. The latch needle bed assembly of this structure can be used as a single When a latch needle is damaged and needs to be replaced, the entire needle block must be replaced together, which not only leads to serious waste, but also increases production costs; the other is an i...

[0002] The latch needle bed assembly in the knitting mechanism of the existing double needle bed warp knitting machine usually adopts the following two structures: one is the needle block type, which is composed of a needle bed base and a large number of needle blocks, and each needle The width of the block is generally 25.4 mm, and several latch needles are bonded and fixed on each needle block by adhesive, and each needle block is fixed on the base of the needle bed by bolts. The latch needle bed assembly of this structure can be used as a single When a latch needle is damaged and needs to be replaced, the entire needle block must be replaced together, which not only leads to serious waste, but also increases production costs; the other is an integrated type, and the latch needle bed assembly of this structure includes the needle bed base 1. Needle groove plate II, latch needles, needle pressing plate and punching plate; Needle groove IIa matching with the latch needle is set on the needle groove plate II along the length direction, and the punching plate presses the tongue through the needle pressing plate. The needle is pressed tightly in the needle groove IIa of the needle groove plate II, and the needle groove plate II and the needle bed base I are integrated, that is, as Figure 15 The one shown is an integral part; during processing, the latch needle is inlaid after milling the needle groove on the entire needle bed formed by the needle groove plate II and the needle bed base I, the length of which is generally 3 to 4 meters, and then the latch needle The needle is fixed by punching plate, needle pressing plate

Although the latch needle bed assembly of this structure has the advantage that a single latch needle can be replaced, it still has the following disadvantages. It is necessary to ensure the consistency and symmetry of the needle grooves of the front and rear needle beds of the double needle bed warp knitting machine. Therefore, the processing accuracy of each needle bed is extremely high, the processing is extremely difficult, and the reject rate is high. The rear needle beds must be used as a set. Therefore, when one of the front and rear needle beds is damaged, the front and rear needle beds must be replaced together, resulting in huge waste and greatly increasing production costs; moreover, the tongue of this structure The needle bed assembly also has the defect of accumulating errors caused by processing and other reasons, which makes the deviation of the needle groove larger with the width of the door. In addition, the distance between the latch needles cannot be adjusted.
