Description

Technical Field

[0001] The invention relates to accessories of a flat knitting machine, in particular to a knitting needle group structure of the flat knitting machine. Background Art

[0002] When the knitting needle combination of the existing flat knitting machine is working, the connecting needle clock needs to be pushed by the mesh triangle along the plane of the needle plate. In order to ensure that the needle clock has sufficient supporting force and does not retract into the groove of the needle plate and is thus controlled by the triangle, the connecting needle needs to have sufficient elastic potential energy. On the contrary, when completing the rest work, the pressure point needs to be subjected to the pressure transmitted from the non-woven pressure plate through the gear control plate to complete elastic deformation, so that the needle clock moves down and retracts into the groove of the needle plate, and gets rid of the control of the triangle mechanism. However, due to the limitations of the pressure point and the design position of the needle clock, the force required for compressive deformation is often much greater than the supporting force required by the needle clock, which will infinitely increase the friction pressure between the non-woven pressure plate and the gear control plate, causing serious wear and consumption of the non-woven pressure plate and the gear control plate, and also pushing up the power demand for the operation of the triangle mechanism. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide a knitting needle group structure of a flat knitting machine, which can reduce the knitting needle combination of the elastic torque, reduce the friction pressure while meeting the support force requirements, and thus reduce the friction force, thereby reducing parts wear and reducing energy loss.

[0004] In order to achieve the above object, the technical solution of the present invention is: A knitting needle group structure of a flat knitting machine includes a knitting needle and a connecting needle, the front of the knitting needle is provided with a needle hook, the needle hook is hinged with a needle tongue, the side of the knitting needle is provided with a spring needle turning piece, and a needle turning groove is formed between the spring needle turning piece and the knitting needle; the connecting needle is provided with a needle clock; the tail of the knitting needle is forked and formed with a connecting groove for the connecting needle to extend into, and a hinge hole is formed at the bottom of the connecting groove; the front end of the connecting needle is provided with a hinge head adapted to the hinge hole; the needle clock is located at a front position on the connecting needle.

[0005] Preferably, the needle clock is located at the front third of the connecting needle.

[0006] Preferably, the tail of the knitting needle is provided with an upper tail fork and a lower tail fork, and the connecting groove is formed between the upper tail fork and the lower tail fork; the hinge hole is located at the intersection of the upper tail fork and the lower tail fork.

[0007] Preferably, the upper surface of the lower tail fork is inclined relative to the length direction of the knitting needle.

[0011] Preferably, the connecting needle is made of elastic material.

[0012] The technical effects of the present invention are mainly reflected in the following aspects: The total length of the connecting needle has been shortened, and the needle clock has been moved to the front third of the connecting needle. Compared to the original product where the needle clock was located in the middle of the product, the maximum elastic potential energy has been reduced by 40% while ensuring that the support force of the needle clock remains unchanged. The connecting needle moves the pressure point forward to the last two-fifths of the connecting needle. Compared with the original product where the pressure point is at one-third of the product, only 60% of the pressure of the original product is required to produce sufficient elastic deformation to complete the rest work.

DETAILED DESCRIPTION

[0015] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0016] Reference Figure 1-4 This embodiment aims to provide a knitting needle group structure of a flat knitting machine, including a knitting needle 1 and a connecting needle 2.

[0017] A needle hook 1-1 is provided at the front of the knitting needle 1, and a needle tongue 1-2 is hinged on the needle hook 1-1. A spring needle turning piece 1-3 is provided on the side of the knitting needle 1, and a needle turning groove 1-8 is formed between the spring needle turning piece 1-3 and the knitting needle 1.

[0018] The tail of the knitting needle 1 is provided with an upper tail prong and a lower tail prong, forming a bifurcated structure. The lower surface of the upper tail prong is parallel to the length of the knitting needle 1, while the upper surface of the lower tail prong is inclined relative to the length of the knitting needle 1. A connecting groove 1-5 is formed between the upper and lower tail prongs, and a hinge hole 1-4 is formed at the bottom of the connecting groove 1-5, i.e., at the intersection of the upper and lower tail prongs.

[0019] The front end of the connecting needle 2 is provided with a hinge head 2-Fc adapted to the hinge hole 1-4, and then the connecting needle 2 extends into the connecting groove 1-5 and is connected to the hinge hole 1-4 through the hinge head 2-Fc, thereby realizing the hinge connection with the knitting needle 1.

[0020] The connecting needle 2 is provided with a needle bell 2-Fb, and the front side of the needle bell 2-Fb is provided with an abutment portion 2-Fb1, and the end of the upper tail fork abuts against the abutment portion 2-Fb1. Preferably, the needle bell 2-Fb is provided at the front third of the connecting needle 2.

[0021] Reference Figure 4-6 The last two-fifths of the connecting needle 2 is set as the pressure point 2-Fa, which is used to cooperate with the gear control plate 3, that is, the front end of the gear control plate 3 abuts against the pressure point 2-Fa. Then, when the front end of the gear control plate 3 is pressed down, the connecting needle 2 can rotate downward relative to the knitting needle 1. Figure 9It can be seen that the knitting needle 1, the connecting needle 2 and the gear control piece are all installed in the needle plate assembly, constrained by the needle plate insert 4 on both sides, supported by the needle plate bottom plate 5 at the bottom, and constrained by the pressure strip 9 at the top.

[0022] The rear end of the connecting needle 2 is configured as a lower fulcrum 2-Fd for contact with the needle plate base 5. The connecting needle 2 is made of an elastic material, ensuring that the needle clock 2-Fb has sufficient support to cooperate with the cam mechanism to complete knitting and other movements. When pressure is applied to the pressure point 2-Fa, it elastically deforms, causing the needle clock 2-Fb to move downward and hide in the needle plate, thereby freeing it from the control of the cam mechanism and completing the resting action.

[0023] Figure 7 、 Figure 8 The structure of a group of knitting needles in an existing product is shown. The second pressure point 7-Fa of the existing product is at the rear third of the product, and the second needle clock 7-Fb is in the middle of the product. Figure 6 、 Figure 7 Comparing the product of this embodiment and the existing product, it can be clearly seen that the overall size of the product of this embodiment is shorter.

[0024] Figure 9 、 Figure 10 The diagram shows a comparison of two states of the knitting needle 1 and the connecting needle 2 being installed in the needle plate group in conjunction with the gear control plate 3, wherein Figure 9 For the workstation, Figure 10 It can be clearly seen that due to the shortening of the overall size of the knitting needle group 1, the size of the needle plate assembly is also shortened, thereby reducing the size of the entire flat knitting machine.

[0025] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
