Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sinkers, and more specifically, it relates to a three-layer sinker with a knitting needle protection structure. Background Art
[0002] The sinker mechanism in a computer flat knitting machine is used to press the knitted fabric downward during knitting to assist the knitting needles in looping off. The sinkers of the two needle beds can be rotated and opened relative to the needle bed mouth to make room for looping, which is beneficial to closing, yarn bending, looping, and pulling in the knitting process. The sinker mechanism generally mainly includes two major parts: sinkers and sinker cam assemblies. The sinkers press down or lift and release the yarn by driving the sinkers with the sinker cam assemblies.
[0003] Existing sinkers are usually arranged in a sheet shape, and a knitting needle and a tooth piece are arranged between two adjacent sinkers. Since space for installing the knitting needle and the tooth piece needs to be left between adjacent sinkers, the knitting needle may shift during operation, thus affecting the knitting accuracy of the knitting needle and the quality of the fabric.
[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Summary of the Utility Model
[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a three-layer sinker with a knitting needle protection structure.
[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A three-layer sinker with a knitting needle protection structure includes a main piece, the main piece includes a body, a driving piece heel and a yarn pressing part are connected to the body, a rotation positioning hole is opened on the body, a first sub-piece is arranged on the surface of the main piece, the first sub-piece is located above the yarn pressing part and the positioning hole, a second sub-piece is further arranged on the surface of the first sub-piece, a knitting needle limiting port is formed between the surface of the first sub-piece and the side of the second sub-piece, and a tooth piece limiting port is formed between the surface of the main piece and the first sub-piece.
[0007] By adopting the above technical solutions, during knitting work, each knitting needle is located between two sinkers. Therefore, a knitting needle limiting groove is formed between the back surface of one sinker and the knitting needle limiting port of the other sinker. The knitting needle reciprocates in this limiting groove during work. Since the knitting needle limiting groove limits the two side surfaces of the knitting needle, the stability of the knitting needle during work is effectively guaranteed, and the knitting accuracy and effect are ensured. Similarly, a tooth piece limiting groove is formed between the back surface of one sinker and the tooth piece limiting port of the other sinker. The tooth piece is located in the tooth piece limiting groove to ensure the overall stability of the internal structure of the flat knitting machine.
[0008] The present utility model is further configured such that the thickness of the main piece is 0.01 - 0.12 mm.
[0009] The present utility model is further configured such that the thickness of the first auxiliary piece is 0.02 - 0.5 mm.
[0010] The present utility model is further configured such that the thickness of the second auxiliary piece is 0.02 - 0.32 mm.
[0011] The present utility model is further configured such that a first smooth coating is provided on the back surface of the main piece.
[0012] The present utility model is further configured such that a second smooth coating is provided at the position of the tooth mouth piece limiting port on the surface of the main piece.
[0013] The present utility model is further configured such that a third smooth coating is provided at the position of the knitting needle limiting port on the surface of the first auxiliary piece.
[0014] The present utility model has the following beneficial effects: When knitting work is carried out, each knitting needle is located between two sinker blades. Therefore, a knitting needle limiting groove is formed between the back surface of one sinker blade and the knitting needle limiting port of the other sinker blade. The knitting needle reciprocates in this limiting groove for work. Since the knitting needle limiting groove limits the two side surfaces of the knitting needle, the stability of knitting during work is effectively guaranteed, and the knitting accuracy and effect are ensured. Similarly, a tooth mouth limiting groove is formed between the back surface of one sinker blade and the tooth mouth limiting port of the other sinker blade. The tooth mouth piece is located in the tooth mouth limiting groove to ensure the overall stability of the internal structure of the flat knitting machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.
[0021] As shown in the figure, a three-layer sinker with a knitting needle protection structure includes a main sinker 1. The main sinker 1 includes a main body 101. A power sinker heel 102 and a yarn pressing part 103 are connected to the main body 101. A rotary positioning hole 104 is formed in the main body 101. A first sub-sinker 2 is arranged on the surface of the main sinker 1. The first sub-sinker 2 is located above the yarn pressing part and the positioning hole. A second sub-sinker 3 is further arranged on the surface of the first sub-sinker 2. A knitting needle limiting port 4 is formed between the surface of the first sub-sinker 2 and the side of the second sub-sinker 3. A sinker mouthpiece limiting port 5 is formed between the surface of the main sinker 1 and the first sub-sinker 2.
[0022] During the knitting operation, each knitting needle is located between two sinkers. Therefore, a knitting needle limiting groove 6 is formed between the back of one sinker and the knitting needle limiting port 4 of the other sinker. The knitting needle reciprocates in this limiting groove. Since the knitting needle limiting groove 6 limits the two side surfaces of the knitting needle, the stability of the knitting during operation is effectively guaranteed, and the knitting accuracy and effect are ensured. Similarly, a sinker mouthpiece limiting groove 7 is formed between the back of one sinker and the sinker mouthpiece limiting port of the other sinker. The sinker mouthpiece is located in the sinker mouthpiece limiting groove 7 to ensure the overall stability of the internal structure of the knitting machine.
[0023] The thickness of the main sinker 1 is 0.01 - 0.12 mm. The thickness of the first sub-sinker 2 is 0.02 - 0.5 mm. The thickness of the second sub-sinker 3 is 0.02 - 0.32 mm. Since different knitting machines have different knitting densities and the distances between adjacent knitting needles and sinker mouthpieces inside them are different, the main sinker 1, the first sub-sinker 2 and the second sub-sinker 3 with different thicknesses are selected for producing this sinker, and the first sub-sinker 2 is fixedly connected to the surface of the main sinker 1 and the second sub-sinker 3 is fixedly connected to the surface of the first sub-sinker 2 through a welding process.
[0024] A first smooth coating 8 is arranged on the back of the main sinker 1. A second smooth coating 9 is arranged on the surface of the main sinker 1 at the position of the sinker mouthpiece limiting port 5. A third smooth coating 10 is arranged on the surface of the first sub-sinker 2 at the position of the knitting needle limiting port 4 to reduce the friction between the knitting needle and the two inner walls of the knitting needle limiting groove 6 and reduce the friction between the sinker mouthpiece and the two inner walls of the sinker mouthpiece limiting groove 7, so as to reduce the wear generated by the knitting needle during operation and improve the service life of the knitting machine.
[0025] The specific embodiments are only explanations of the present utility model, and they do not limit the present utility model. After reading this specification, those skilled in the art can make modifications to these embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
