Description

Technical Field

[0001] The utility model relates to the relevant field of straight double-mounted plates, in particular to a needle lifting and reversing mechanism for a motor-type straight double-mounted plate. Background Art

[0002] The computerized flat knitting machine is a double-needle plate latch needle weft knitting loom. Its triangle device is like a set of flat cams. The pins of the knitting needles can enter the grooves of the cams and move the triangles, forcing the knitting needles to make regular lifting and lowering movements in the needle grooves of the needle plate. Through the actions of the needle hooks and needle tongues, the yarns can be woven into knitted fabrics. During the rising process of the knitting needles, the coils gradually withdraw from the needle hooks, open the needle tongues, and withdraw from the needle tongues to hang on the needle bar; during the descending process of the knitting needles, the needle hooks hook the newly placed yarns and pull and bend them into coils. At the same time, the original coils come out of the needle hooks, and the new coils pass through the old coils and are connected in series with the old coils. The coil strings formed by numerous knitted fabrics are connected to each other to form knitted fabrics.

[0003] When optimizing the existing needle lifting and reversing mechanisms for motor-type straight double mountain boards, most of them are reflected in aspects that are conducive to cost reduction and efficiency improvement. For example, the Chinese utility model patent with patent number CN208815232U discloses "A needle lifting and reversing mechanism for motor-type single and double mountain boards", which includes a base plate, and two sets of needle lifting and reversing devices are symmetrically arranged on the bottom of the base plate. The needle lifting and reversing devices include a fixed needle lifting triangle arranged at the front end of the base plate and a reversing device arranged in the middle of the base plate. The reversing device includes a reversing triangle block fixed to the base plate, and a linkage block is slidably connected in the reversing triangle block. The linkage block is provided with a linkage pin on one side of the back side of the base plate. The back side of the base plate is pinned with a connecting rod with one end abutting the linkage pin, and the other end of the connecting rod is provided with an iron block. The back side of the base plate is also provided with an electromagnet that attracts the iron block to drive the connecting rod to drive the linkage block to move up and down to achieve needle lifting and reversing.

[0004] Although the above-mentioned motor-type straight double-mount plate with lifting needle reversing mechanism has certain advantages in terms of reducing costs and increasing efficiency, it still has certain disadvantages:

[0005] like Figure 7As shown, three needle selectors can be used to achieve the weaving efficiency formed by simply splicing two single systems (each single system contains two needle selectors). Two needle lifting and reversing devices can make the needles moving from left to right and from right to left reverse the weaving, forming synchronous reciprocating weaving, which greatly improves the efficiency. The parts are relatively greatly reduced, which can increase the speed of the machine head movement, which is beneficial to cost reduction and efficiency improvement. However, the needle lifting and reversing mechanism for the straight double mountain plate of the above-mentioned motor type needs to be disassembled for lubrication, and then the straight double mountain plate and the needle lifting and reversing mechanism need to be lubricated. Repeated disassembly of the straight double mountain plate and the needle lifting and reversing mechanism will easily lead to a decrease in the accuracy of the straight double mountain plate and the needle lifting and reversing mechanism, and the operation is complicated. When too much lubricating oil is applied, it is easy to cause waste of lubricating oil. Utility Model Content
