Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plush knitting, especially to a novel hook-knife combined structure. BACKGROUND

[0002] The existing plush circular knitting machine produces fabric plush mainly by using conventional hook-knives. The principle is to install the hook-knives on the lower needle cylinder, cooperate with the lower disc cam assembly, upper needle disc knitting needle and presser wheel assembly to complete the loop cutting action, thereby forming the plush effect. The presser wheel assembly plays a role in fixing the yarn to assist the hook-knife in cutting the loop during the entire loop cutting process.

[0003] The applicant applied for a patent for a novel hook-knife combined structure with the patent application number 201720091062.7 on January 22, 2017. The patent discloses that the left hook, right hook and cutting knife are combined to form a whole, and the left hook, right hook and cutting knife are placed in the same needle groove. The left hook is provided with a left hook needle rod, left hook needle foot and left hook needle hook. The right hook is provided with a right hook needle rod, right hook needle foot and right hook needle hook. The cutting knife is provided with a cutting knife needle rod, cutting knife needle foot and cutting knife edge. The original plush machine hook-knife structure is disassembled into a hook-knife combined structure. The hook and knife actions can be controlled separately by using the cam track. When pulling the yarn, the hook can be controlled to pull the loop to the desired length of the yarn by the cam track. The cutting knife can be controlled to cut the loop to form the plush by the cam track. The presser wheel assembly is no longer needed to assist in the knitting of the plush fabric. The machine is simpler and more convenient to debug. The installation space is small, and the scope of application is wide.

[0004] The plush loop is hooked by the left hook needle hook and right hook needle hook, and then the yarn is bent and cut by the cutting knife. However, the hook-knife combined structure described above is prone to cause the yarn to bend and mark the loop, which affects the appearance. The yarn is also prone to fly due to the tight bending and cutting. UTILITY MODEL CONTENTS

[0005] Therefore, in view of the above problems, the utility model provides a novel hook-knife combined structure, which mainly solves the problem of the hook-knife combined structure in the prior art being prone to cause the yarn to bend and mark the loop, which affects the appearance, and the yarn being prone to fly due to the tight bending and cutting.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A novel hook knife assembly structure includes a left hook, a right hook, a spacer, and a cutting knife. The left hook includes a left needle bar, a left needle hook at the upper end of the left needle bar, and a left needle heel at the lower part of the left needle bar. The right hook includes a right needle bar, a right needle hook at the upper end of the right needle bar, and a right needle heel at the lower part of the right needle bar. The spacer includes a plate body and a plate body needle heel at the lower part of the plate body.

[0008] The spacer is disposed between the left hook and the right hook, and the spacer is welded to the left hook and the right hook respectively. The left heel of the left hook, the right heel of the right hook, and the heel of the spacer body coincide. The width of the left needle bar and the right needle bar is greater than the width of the spacer body, so that a cutting groove is formed between the left needle bar and the right needle bar. The cutting knife is disposed in the cutting groove.

[0009] The left needle hook has a first stepped groove recessed on one side near the spacer, so that the thickness of the left needle hook is 0.05mm to 0.20mm less than the thickness of the left needle bar. The right needle hook has a second stepped groove recessed on one side near the spacer, so that the thickness of the right needle hook is 0.05mm to 0.20mm less than the thickness of the right needle bar.

[0010] Furthermore, the tangent includes a shank, a cutting edge located at the upper end of the shank, and a tangent needle heel located at the lower part of the shank.

[0011] Furthermore, the width of the tool holder is greater than the depth of the tool groove.

[0012] Furthermore, the connection points of the left needle heel and the left needle rod, the right needle heel and the right needle rod, the connection points of the tangent needle heel and the tangent rod, and the connection points of the plate body and the plate body needle heel are all provided with clearance grooves.

[0013] Furthermore, the lower part of the sheet body, and the side near the knife groove, is provided with a rounded corner.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: In use, the new hook-knife combination structure has the left hook, right hook, and spacer embedded in a needle groove of the syringe or needle plate. The left heel of the left hook, the right heel of the right hook, and the heel of the spacer are embedded in a triangular track for synchronous control. The tangent is positioned in a knife groove, and its tangent heel is embedded in another triangular track, allowing the tangent to slide within the knife groove. The yarn is hooked by the left hook and the right hook, and then... The drive cutter cuts the yarn, and the left and right hooks are respectively provided with a first stepped groove and a second stepped groove on the side near the spacer. This makes the thickness of the left hook 0.05mm to 0.20mm less than the thickness of the left needle bar, and the thickness of the right hook 0.05mm to 0.20mm less than the thickness of the right needle bar. As a result, when the cutter cuts the yarn, the yarn end is less likely to form a bending mark, improving the appearance of the product, and preventing the generation of flying lint due to excessively tight bending and cutting.

The tangent 4 includes a blade 41, a blade 42 located at the upper end of the blade 41, and a tangent 43 located at the lower part of the blade 41.

[0022] The spacer 3 is disposed between the left hook 1 and the right hook 2, and the spacer 3 is welded to the left hook 1 and the right hook 2 respectively. The left needle heel 13 of the left hook 1, the right needle heel 23 of the right hook 2 and the plate needle heel 32 of the spacer 3 overlap. The width of the left needle bar 11 and the right needle bar 21 is greater than the width of the plate 31, so that a cutting groove 5 is formed between the left needle bar 11 and the right needle bar 21. The cutting knife 4 is disposed in the cutting groove 5. The width of the cutting knife 41 is greater than the depth of the cutting groove 5.

[0023] The left needle hook 12 has a first stepped groove 6 recessed on one side near the spacer 3, so that the thickness of the left needle hook 12 is 0.05mm to 0.20mm less than the thickness of the left needle bar 11, preferably 0.15mm. The right needle hook 22 has a second stepped groove 7 recessed on one side near the spacer 3, so that the thickness of the right needle hook 22 is 0.05mm to 0.20mm less than the thickness of the right needle bar 21, preferably 0.15mm.
