Description

Technical Field

[0001] This utility model relates to the field of plush knitting equipment, and in particular to a hook knife combination structure for plush knitting machines. Background Technology

[0002] In existing circular knitting machines, the production of fabric pile is mainly accomplished using conventional hook cutters. The principle is to install the hook cutter on the lower needle cylinder, and work with the lower disc triangular assembly, the upper needle disc knitting needles, and the pressing wheel assembly to complete the loop cutting action, thereby creating a pile effect. During the entire loop cutting process, the pressing wheel assembly plays the role of fixing the yarn and assisting the hook cutter in cutting the loop.

[0003] On January 22, 2017, the applicant filed a patent application with patent number 201720091062.7, entitled "A Novel Hook and Knife Combination Structure". The patent discloses a combination of three parts: a left hook, a right hook, and a cutter. The left hook, right hook, and cutter are placed together on the same needle groove. The left hook is provided with a left hook needle rod, a left hook needle foot, and a left hook needle hook. The right hook is provided with a right hook needle rod, a right hook needle foot, and a right hook needle hook. The cutter is provided with a cutter needle rod, a cutter needle foot, and a cutter blade. By disassembling the original hook and knife structure of the plush machine into a hook and knife combination structure, the hook and knife actions can be controlled separately using a triangular track. When pulling the yarn, the triangular track controls only the hook to pull the loop into the desired yarn length position, and then the triangular track controls the cutter to cut the loop and form the plush. The plush fabric can be woven without the need for the pressing wheel assembly, making the machine simpler and more convenient to debug, requiring less installation space and having a wider range of applications.

[0004] However, during use, it was found that when weaving plush fabric with a high loop density, the colored yarns are arranged more tightly. During the hooking process, it is not easy to hook two adjacent colored yarns, which causes defects in the woven plush fabric and reduces product quality. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a hook knife combination structure for a plush machine, which mainly solves the problem that in the prior art, the hook needle is not easy to hook two adjacent colored yarns, resulting in defects in the woven plush fabric.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hook knife assembly structure for a plush machine includes a left hook needle, a right hook needle, a connector, and a cutter, all placed in the same needle groove. The connector is located between the left and right hook needles and is fixedly connected to both. The connector forms a sliding groove between the left and right hook needles. Both the left and right hook needles have a yarn-separating nose protruding from their upper ends. The two yarn-separating noses are separated by the sliding groove. Each of the two yarn-separating noses has a first vertical edge and a second inclined edge. The cutter is located in the sliding groove and slides along the groove.

[0008] Furthermore, the left hook includes a left needle bar, a left hook portion located at the upper end of the left needle bar, and a left needle heel located at the lower part of the left needle bar; the right hook includes a right needle bar, a right hook portion located at the upper end of the right needle bar, and a right needle heel located at the lower part of the right needle bar; the connector includes a connector body and a connector needle heel located at the lower part of the connector body; the left needle heel, the right needle heel, and the connector needle heel are fixedly connected and placed within the same triangular track.

[0009] Furthermore, the cutter includes a cutter bar, a cutter blade located at the upper end of the cutter bar, and a cutter needle heel located at the lower part of the cutter bar, with the cutter needle heel and the left needle heel respectively placed in different triangular tracks.

[0010] Furthermore, the first vertical edge is close to the front end of the left hook, the second inclined edge is close to the rear end of the left hook, and the inclination angle of the first vertical edge is greater than the inclination angle of the second inclined edge.

[0011] Furthermore, the left hook, right hook, and connector are provided with a lint-removing groove on one side near the needle groove.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This hook-and-knife assembly structure for a plush machine, by setting a connecting piece between the left and right hook needles to form a sliding groove, and the yarn-separating noses protruding from the upper ends of the left and right hook needles separating through the sliding groove, allows the cutter to be positioned within the sliding groove and slide along it. This enables the yarn-separating noses to effectively separate colored yarns when weaving plush fabric with a high loop density, and brings colored yarns on the same side closer together. This makes it easier for the hook needle to hook two adjacent colored yarns during the initial hooking process, thereby reducing defects in the woven plush fabric and improving product quality. This invention solves the problem in existing technologies where hooks easily snag adjacent colored yarns, causing defects in the plush fabric. Specifically, the left and right hooks start simultaneously, and the adjacent colored yarns are separated by the yarn separating nose. That is, the first colored yarn slides and separates from the second colored yarn through the second inclined edge of the yarn separating nose, and the second inclined edge pushes the colored yarn on the back side to the back of the left and right hooks, making it easier for the left and right hooks to snag the other colored yarn. At the same time, the first vertical edge of the yarn separating nose is used to adjust the measuring surface, so that the second colored yarn feed nozzle is close to the second colored hook, which facilitates the installation and adjustment of the left and right hooks and makes it easy to use. Attached Figure Description

[0013] Figure 1 This is a front view structural diagram of an embodiment of the present utility model;

[0014] Figure 2 This is an exploded structural diagram of an embodiment of the present invention. Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] The embodiment of this utility model is as follows:

[0017] refer to Figure 1 and Figure 2 As shown, a hook knife assembly structure for a plush machine includes a left hook 1, a right hook 2, a connector 3, and a cutter 4, all placed in the same needle groove. The connector 3 is located between the left hook 1 and the right hook 2 and is fixedly connected to both hook 1 and hook 2. The connector 3 forms a sliding groove 5 between the left hook 1 and the right hook 2. The upper ends of both the left hook 1 and the right hook 2 are provided with yarn separating noses 6. The two yarn separating noses 6 are separated by the sliding groove 5. Each of the two yarn separating noses 6 has a first vertical edge 61 and a second inclined edge 62. The cutter 4 is located in the sliding groove 5 and slides along the sliding groove 5.

[0018] This hook-and-knife assembly structure for plush knives utilizes a connecting piece 3 between the left hook 1 and the right hook 2 to form a sliding groove 5. The yarn-separating noses 6 protruding from the upper ends of the left and right hooks separate through this sliding groove 5. A cutter 4 is positioned within the sliding groove 5 and can slide along it. This allows the yarn-separating noses 6 to effectively separate colored yarns when weaving plush fabric with high loop density, bringing colored yarns on the same side closer together. This makes it easier for the hook to catch adjacent colored yarns during the initial hooking process, reducing defects in the woven plush fabric, improving product quality, and solving the problem of hooks easily catching yarns in existing technologies. To address the issue of defects in plush fabric caused by hooking two adjacent colored yarns, the left hook 1 and right hook 2 start simultaneously. The adjacent colored yarns are separated by the yarn separating nose 6. Specifically, the first colored yarn slides through the second inclined edge 62 of the yarn separating nose 6 to separate from the second colored yarn. The second inclined edge 62 also pushes the colored yarn on the back of the left and right hooks to the back, making it easier for the left and right hooks to hook the other colored yarn. At the same time, the first vertical edge of the yarn separating nose 6 is used to adjust the measuring surface so that the second colored yarn feed nozzle is close to the second colored hook, which facilitates the installation and adjustment of the left and right hooks and makes them easy to use.

[0019] Specifically, the left hook 1 includes a left needle bar 11, a left hook portion 12 located at the upper end of the left needle bar 11, and a left needle heel 13 located at the lower part of the left needle bar 11. The right hook 2 includes a right needle bar 21, a right hook portion 22 located at the upper end of the right needle bar 21, and a right needle heel 23 located at the lower part of the right needle bar 21. The connector 3 includes a connector body 31 and a connector needle heel 32 located at the lower part of the connector body 31. The left needle heel 13, the right needle heel 23, and the connector needle heel 32 are fixedly connected and placed in the same triangular track, so that the left and right hooks and the connector can move in coordination under the control of the triangular track, ensuring the stability and consistency of the movement of the hook part during the knitting process, further optimizing the hook yarn hooking process, helping to control the hook yarn more accurately, reducing the hook yarn errors caused by uncoordinated movements, and thus improving the quality of knitted plush fabric.

[0020] Furthermore, the cutting blade 4 includes a cutting blade rod 41, a cutting blade edge 42 located at the upper end of the cutting blade rod 41, and a cutting blade heel 43 located at the lower part of the cutting blade rod 41. The cutting blade heel 43 and the left needle heel 13 are respectively placed in different triangular tracks, so that the cutting blade 4 and the left and right hooks can be independently controlled by different triangular tracks. During the knitting process, the timing and range of the cutting blade and the left and right hooks can be controlled more flexibly. For example, when pulling the yarn, the hooks can be controlled more precisely to pull the loop into the desired yarn length position first, and then the cutting blade can be accurately controlled to cut the loop to form the pile. There is no need for the assistance of the pressing wheel assembly, which makes the machine debugging simpler and more convenient. At the same time, it improves the accuracy of knitting and the pile effect, and expands the scope of application.

[0021] Furthermore, the first vertical edge 61 is close to the front end of the left hook 12, and the second inclined edge 62 is close to the rear end of the left hook 12. The inclination angle of the first vertical edge 61 is greater than that of the second inclined edge 62, which allows the yarn nose tip 6 to guide the colored yarn more effectively during the yarn hooking process, so that the colored yarn enters the hook more smoothly, while avoiding the accidental hooking of adjacent colored yarns. This further reduces the probability of defects in the woven plush fabric and improves the accuracy of weaving and product quality.

[0022] In this embodiment, the left hook 1, right hook 2, and connector 3 are recessed on one side near the needle groove with a lint-removing groove 7. The lint-removing groove 7 can reduce the contact area with the needle groove, reduce interference and friction between the two, make the movement of the entire hook knife assembly structure in the needle groove smoother, reduce the failure rate caused by friction between components, and at the same time can accommodate the cotton lint generated after the colored yarn is cut, improve the stability and reliability of machine operation, thereby ensuring the smooth progress of the weaving process and improving weaving efficiency and product quality.
