Detailed Description of the Preferred Embodiment
[0020] The present utility model will be further described in detail below with reference to the drawings and embodiments.
[0021] Embodiment 1
[0022] A horizontal knitting machine insert needle plate, as shown in the figure, includes a bottom plate 1, and also includes a toothed mouthpiece 2. The front end of the bottom plate 1 is provided with a toothed mouth slot 11 that is parallel to the toothed mouthpiece 2 and vertically arranged, and the toothed mouthpiece 2 is matched with the toothed mouth slot 11; the front end of the bottom plate 1 is also provided with a toothed mouth card slot 12, the toothed mouth card slot 12 is located in the front part of the toothed mouth slot 11, and the toothed mouthpiece 2 is provided with a buckle protrusion 21 that is matched with the toothed mouth card slot 12.
[0023] The toothed mouth card slot 12 is horizontally arranged and penetrates through a plurality of toothed mouth slots 11.
[0024] The toothed mouth slot 11 is opened at the front end of the bottom plate 1, the toothed mouth slot 11 extends backward, and the bottom of the toothed mouth slot 11 is inclined downward and the inclination angle with the horizontal plane of the bottom plate 1 is 38°.
[0025] The buckle protrusion 21 is located at the upper matching part where the toothed mouthpiece 2 is matched with the toothed mouth slot 11, and the buckle protrusion 21 protrudes downward and is inserted into the toothed mouth card slot 12 for matching.
[0026] The lower surface of the toothed mouth position of the bottom plate 1 is horizontally provided with a toothed mouth hook slot 16, and the lower part of the toothed mouthpiece 2 is provided with a hook part 23, and the hook part 23 is hung on the toothed mouth hook slot 16.
[0027] Embodiment 2
[0028] Same as Embodiment 1, the difference is that the lower parts of the toothed mouthpieces 2 are all provided with toothed mouth positioning holes 22, and the toothed mouthpieces 2 are connected by steel wires passing through the toothed mouth positioning holes 22. The steel wires passing through the toothed mouth positioning holes 22 of the toothed mouthpieces 2 are used to fix the toothed mouthpieces 2, so that multiple toothed mouthpieces 2 are connected into a whole, increasing the toothed mouth stability; making the assembly and disassembly of the needle plate more convenient. During the production process, the production efficiency can be greatly improved and the waste of working hours can be reduced; in actual use, once the toothed mouthpiece 2 is worn or damaged, only the toothed mouthpiece 2 needs to be replaced separately, without replacing the whole needle plate, which further reduces the use cost and the maintenance difficulty.
[0029] Embodiment 3
[0030] Same as Embodiment 1, the difference is that the bottom plate 1 is provided with an insert slot 13, and also includes an insert 3 that is matched with the insert slot 13. The gap between adjacent inserts 3 is a needle slot 14. The insert 3 is provided with a dovetail slot 31 and a steel wire hole 32, and also includes a pin that is matched with the dovetail slot 31 and a steel wire for the steel wire hole 32, and multiple inserts 3 are connected by the pin and the steel wire.
[0031] The front end of the bottom plate 1 is also provided with a knitting needle positioning slot 15. The knitting needle positioning slot 15 is arranged at intervals with the toothed mouth slot 11. The knitting needle positioning slot 15 is coaxially arranged with the needle slot 14, and the toothed mouth card slot 12 horizontally penetrates through the knitting needle positioning slot 15.
[0032] Embodiment 4
[0033] The same as the embodiment 1, except that the insert 3 of the bottom plate 1 is provided with a needle selector 4, and the needle selector 4 is provided with an upper limit hole 41 and a lower limit hole 42, and the upper limit hole 41 and the lower limit hole 42 are both matched with a limit wire, and the needle selector 4 can be translated forward and backward in the middle of the limit wire, and the upper limit hole 41 and the lower limit hole 42 are both round holes. After the original upper limit dovetail groove of the needle selector 4 is changed to a round hole design, the complexity and difficulty of processing are significantly reduced. The processing technology of the round hole is relatively mature, and the precision is easier to control, thereby improving the production efficiency and quality consistency of the needle selector. At the same time, the structure of the round hole makes the needle selector more evenly stressed during the working process, reduces the stress concentration phenomenon, and prolongs the service life of the needle selector.
[0034] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
