Description

Technical Field

[0001] The present invention relates to the technical field of knitting machines, and more particularly to a flat tape yarn guiding mechanism for a knitting machine. Background Art

[0002] Currently, the knitting of sunshade nets is mainly carried out by textile machines. The knitting threads used for sunshade nets are mainly strip-shaped PE or PP material threads. The strip-shaped PE or PP material threads are used as weft threads (flat tape yarns), and thin threads are used as warp threads, and they are knitted by a knitting machine to produce sunshade nets. During the knitting process, since there are no requirements for the posture of the strip-shaped PE or PP material threads, during the yarn guiding process, the flat tape yarns are flipped during the yarn feeding process, and the flat tape yarns cannot be neatly laid flat, resulting in serious light leakage and unevenness in the knitted sunshade nets, and the yarns of the flat tapes are squeezed, folded and flipped. In order to improve the knitting quality, a guiding mechanism needs to be added during the yarn feeding process. However, the existing guiding mechanisms are all for thin threads and lack the design of combing and guiding for such flat strip-shaped yarns. Utility Model Content

[0003] In order to solve the above technical problems and drawbacks: how to comb and guide flat strip-shaped yarns, the present invention provides a flat tape yarn guiding mechanism for a knitting machine, which can achieve the purpose of convenient assembly and fast combing and guiding.

[0004] To achieve the above object and other related objects, the present invention adopts the following technical solutions:

[0005] A flat tape yarn guiding mechanism for a knitting machine includes a guiding assembly. The guiding assembly includes a guiding tube and a support. One end of the guiding tube is a circular inlet, and the other end of the guiding tube is a crescent-shaped outlet. The outlet includes a middle part and two corner parts. A stamping recess is provided at the outlet of the guiding tube, and the stamping recess forms the outlet. The stamping recess has a curved surface that is recessed inward.

[0006] At least one slot is provided on the support, and the guiding tube is inserted into the slot.

[0007] Preferably, an upper fastening hole is provided above the slot on the support, a fixing groove is provided below the support, and a lower fastening hole is provided below the fixing groove.

[0008] Preferably, the inner diameter of the inlet is adjusted according to the width of the flat tape yarn, and the range of the inner diameter of the inlet is: 1.2 times to 1.8 times the width of the flat tape yarn.

[0009] Preferably, the distance between the middle parts is less than the width of the flat tape yarn.

[0010] Preferably, the spacing in the middle is 0.25 - 0.3 times the inner diameter of the inlet.

[0011] Preferably, through slots are provided between multiple said slots to make them communicate with each other. The upper fastening hole is located at the position between two slots, and the slots are parallel to each other.

[0012] Preferably, an opening is provided on the fixing groove, and the lower fastening hole is arranged at the opening position. The fixing groove is used for being assembled on the cross bar of the knitting machine.

[0013] In summary, the present invention includes at least one of the following beneficial technical effects:

[0014] 1. By using the guide tube installed and fixed on the support, the position of the guide tube on the cross bar of the knitting machine is fixed. When the flat tape yarn passes through this guide tube, the resistance at the inlet is small. As the yarn is pulled by traction, the yarn adjusts its posture at the crescent-shaped outlet and is directly smoothed by this outlet. Since the stamping recess at the outlet is curved, the process of smoothing the yarn is relatively gentle and the yarn will not break. Multiple guide tubes can be assembled on the support through multiple slots to improve the yarn knitting efficiency;

[0015] 2. To facilitate the installation of the guide tube, it can be assembled by plugging, and then the installation of the guide tube is further strengthened on the fastening hole by using bolts for fastening;

[0016] 3. In order to be able to smooth it more effectively, it is necessary to adapt the sizes of the inlet and outlet to the width of the yarn to achieve the effect of smooth inlet and outlet of the wire. If the inlet and outlet are too small, the yarn is easily squeezed, increasing the frictional resistance. If the inlet and outlet are too large, it is not easy to limit the yarn and it cannot be smoothed;

[0017] 4. In order to be able to be effectively installed on the cross bar, an opening is also provided on the fixing groove, which improves the efficiency and convenience of assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment:

[0030] The embodiment of the present invention discloses a flat tape yarn guiding mechanism for a knitting machine. The flat tape yarn 4 can be a wire made of PE or PP material. Refer to Figure 1 and Figure 2 As shown, it includes a guiding component. The guiding component includes a guide tube 1 and a support 2. One end of the guide tube 1 is a circular inlet 11, and the other end of the guide tube 1 is a crescent-shaped outlet 12. The outlet 12 includes a middle part 121 and two corner parts 122. A stamped recess 13 is provided at the outlet 12 of the guide tube 1. The stamped recess 13 forms the outlet 12. The stamped recess 13 has a curved surface that is recessed inward. At least one slot 21 is provided on the support 2, and the slot 21 is for the guide tube 1 to be inserted. In this embodiment, it is shown that two slots 21 are designed on one support 2.

[0031] Working process: The guiding tube 1 is installed and fixed on the support 2, so that the position of the guiding tube 1 on the cross bar 3 of the knitting machine is fixed. When the flat tape yarn 4 passes through this guiding tube 1, the resistance at the inlet 11 is small. As the yarn is pulled by traction, the yarn adjusts its posture at the crescent-shaped outlet 12 and is directly smoothed by this outlet 12. Since the stamping recess 13 at the outlet 12 is curved, the process of smoothing the yarn is relatively gentle and the yarn will not break. Multiple guiding tubes 1 can be assembled on the support 2 through multiple slots 21 to improve the yarn knitting efficiency.

[0032] For the convenience of assembly, upper fastening holes 22 are provided above the slots 21 on the support 2, a fixing groove 23 is provided below the support 2, and lower fastening holes 24 are provided below the fixing groove 23. In this way, it is easier to install the guiding tube 1. After determining the position of the guiding tube 1 by the direct insertion method, bolts are installed on the upper fastening holes 22 to press the guiding tube 1.

[0033] Reference Figure 3 Understand that the inner diameter of the inlet 11 is adjusted according to the width of the flat tape yarn 4, and the inner diameter of the inlet 11 is L1 + L2. The range of the inner diameter of the inlet 11 is: 1.2 times to 1.8 times the width of the flat tape yarn 4. Generally, the width of the flat tape yarn 4 is 2.5 mm - 3.5 mm. The thickness of the flat tape yarn is generally 0.025 mm - 0.035 mm. The distance L1 between the middle parts 121 is less than the width of the flat tape yarn 4. The distance (L1) between the middle parts 121 is 0.25 - 0.3 times the inner diameter (L1 + L2) of the inlet 11. In order to be able to smooth it more effectively, it is necessary to adapt the sizes of the inlet and outlet 12 to the yarn width to achieve the effect of smooth entry and exit of the yarn. If the inlet and outlet 12 are too small, the yarn is easily squeezed, increasing the frictional resistance. If the inlet and outlet 12 are too large, it is not easy to limit the yarn and it cannot be smoothed.

[0034] A through slot 25 is provided between multiple slots 21 to make them communicate with each other. The upper fastening holes 22 are located at the position between two slots 21, and the slots 21 are parallel to each other. An opening 26 is provided on the fixing groove 23, and the lower fastening holes 24 are provided at the position of the opening 26. The fixing groove 23 is used to be assembled on the cross bar 3 of the knitting machine.

[0035] For the convenience of installing the guiding tube 1, it can be assembled by the plug-in method, and then the installation of the guiding tube 1 is further strengthened on the fastening holes by the bolt fastening method; in order to be effectively installed on the cross bar 3, an opening 26 is also provided on the fixing groove 23, which improves the assembly efficiency and convenience.

[0036] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent changes made according to the structure, shape, and principles of the present invention should be covered within the protection scope of the present invention.
