Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting technology, and in particular to a transfer needle and a circular knitting machine. Background Technology
[0002] The knitting process of a transfer stitch on a knitting machine involves a transfer needle with an expander plate advancing to enlarge the loop, followed by the corresponding receiving needle advancing so that its hook passes through the hole formed by the expander plate and the knitting needle body in the transfer needle, simultaneously passing through the enlarged loop. The transfer needle then retracts, transferring the loop to be transferred into the receiving needle's hook. With market development and customer demand for increasingly finer gauge fabrics, the thickness of the transfer needles is decreasing, and the gap left for the receiving needle to pass through the hole formed by the expander plate and the knitting needle body is becoming very small. As the transfer needle expands the loop, the loop also compresses the expander plate, further reducing the size of the hole formed by the expander plate and the knitting needle body. These factors contribute to difficulties in transfer stitching and even failure. To address these problems, this design improves the transfer needle. Utility Model Content
[0003] To overcome the shortcomings of the existing technology, this utility model provides a transfer needle and a circular machine that improves the transfer error tolerance rate.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A transfer needle includes a needle body and an expanding plate. The expanding plate is disposed on one side of the needle body. The rear end of the expanding plate is fixedly connected to the needle body. The front end of the expanding plate is close to the side of the needle body. The middle section of the expanding plate is bent so that a needle hole is formed between the side of the expanding plate and the side of the needle body. The expanding plate is provided with a first guide section. The first guide section is inclinedly opened from the bottom surface of the expanding plate to the side facing the needle hole and extends along the length direction of the expanding plate, so that the needle hole forms a flared structure at the position of the first guide section.
[0005] Furthermore, the needle body is provided with a second guide section, which is inclinedly opened from the bottom surface of the needle body to the side facing the needle hole and extends along the length of the needle body, so that the needle hole forms a flared structure at the position of the second guide section.
[0006] Furthermore, the length range of the second guide segment covers the length range of the first guide segment.
[0007] Furthermore, the angle between the first guide segment and the vertical plane is 15° to 35°, and the angle between the second guide segment and the vertical plane is 15° to 35°.
[0008] Furthermore, the needle tip of the knitting needle body is provided with a third guide section, which is inclined from front to back at the needle tip and extends along the vertical direction of the knitting needle body.
[0009] Furthermore, the third guide section is provided on one or both sides of the needle tip, and the angle between the third guide section and the vertical plane is 25° to 45°.
[0010] Furthermore, a first groove is provided on the side wall of the knitting needle body, and the rear end of the expanding piece is embedded in the first groove.
[0011] Furthermore, a second groove is provided on the side wall of the knitting needle body, and the front end of the expanding piece is inserted into and adhered to the second groove.
[0012] A circular knitting machine includes an upper needle plate and a lower needle cylinder. The upper needle plate is provided with an upper needle, and the lower needle plate is provided with a lower needle. The upper needle and / or the lower needle adopts one of the above-mentioned transfer needles.
[0013] As can be seen from the above description of this utility model, compared with the prior art, the loop transfer needle and circular knitting machine provided by this utility model have the following advantages: By setting a first guide section on the expanding plate, the needle hole is widened, improving the error tolerance rate of the loop-connecting needle entering the needle hole and ensuring the success rate of loop transfer. The setting of a second guide section on the needle body further improves the widening structure of the needle hole, further ensuring the success rate of loop transfer. The third guide section at the needle tip makes the needle tip form a narrow front and wide back structure, further ensuring the success rate of loop transfer. The multiple guide structures of this solution improve the success rate of the loop-connecting needle passing through the needle hole, and have important application value in the trend of high-speed and precision development of knitting machinery.

[0025] The present invention will be further described below through specific embodiments.
[0026] Reference Figures 1 to 6 As shown, a loop transfer needle includes a needle body 1 and a loop expander 2. The loop expander 2 is disposed on one side of the needle body 1, with its rear end fixedly connected to the needle body 1. The front end of the loop expander 2 is close to the side of the needle body 1, and the middle section of the loop expander 2 is bent, forming a needle hole 3 between the side of the loop expander 2 and the side of the needle body 1. The loop expander 2 has a first guide section 21, which is inclinedly opened from the bottom surface of the loop expander 2 to the side facing the needle hole 3 and extends along the length of the loop expander 2, so that the needle hole 3 forms a flared structure at the position of the first guide section 21. The flared structure increases the width of the entry end of the needle hole 3, which is beneficial for the needle tip of the looper needle to pass through. When the looper needle is not accurately inserted into the needle hole 3, the tip of the needle can be guided and pushed into the needle hole 3 by the first guide section 21, reducing the possibility of loop transfer failure caused by assembly or operation errors.
[0027] In this embodiment, the needle body 1 is provided with a second guide section 11. The second guide section 11 is inclinedly opened from the bottom surface of the needle body 1 to the side facing the needle hole 3 and extends along the length direction of the needle body 1, so that the needle hole 3 forms a flared structure at the position of the second guide section 11. The length range of the second guide section 11 covers the length range of the first guide section 21. The angle between the first guide section 21 and the vertical plane is 15° to 35°, preferably 20° in this embodiment. The second guide section 11 further increases the flared width of the needle hole 3, further improving the smoothness of the loop-connecting needle passing through the needle hole 3 and ensuring successful loop transfer.
[0028] In this embodiment, the needle tip of the needle body 1 is provided with a third guide section 12. The third guide section 12 is inclined from front to back at the needle tip and extends along the vertical direction of the needle body 1. The third guide section 12 is provided on one or both sides of the needle tip, and the angle between the third guide section 12 and the vertical plane is 25° to 45°, with a preferred embodiment being 33°. The third guide section 12 makes the needle tip form a structure that is narrow at the front and wide at the back, further improving the success rate of the needle tip passing through the needle hole 3 and further ensuring the success of loop transfer.
[0029] In this embodiment, a first groove 13 is formed on the side wall of the needle body 1, and the rear end of the expanding piece 2 is embedded in the first groove 13. A second groove 14 is formed on the side wall of the needle body 1, and the front end of the expanding piece 2 is inserted into and pressed against the second groove 14. This structure facilitates the assembly of the transfer needle and can reduce the overall thickness of the transfer needle while ensuring the strength of the needle body.
[0030] A circular knitting machine includes an upper needle plate and a lower needle cylinder. The upper needle plate is provided with an upper needle, and the lower needle plate is provided with a lower needle. The upper needle and / or the lower needle adopts the above-mentioned transfer needle.
[0031] The working principle of this application will be further explained below through the action of moving circles.
[0032] In this embodiment, both the upper and lower needles use the loop transfer needles with the structure described in this application.
[0033] refer to Figure 7 In the state shown, the purl needle acts as a transfer needle, and the knitting needle acts as a receiving needle. When the purl needle comes out, the loop is placed on the needle body 1 and the expander plate 2, thus expanding the loop.
[0034] refer to Figure 8 In the indicated state, the needle rises and passes through the needle hole 3. The needle passes through the flared structure formed by the first guide section 21 and the second guide section 11. During this process, if the needle does not accurately align with the needle hole 3, it will slide into the needle hole 3 guided by the first guide section 21 or the second guide section 11 through the tip of the needle. (See reference...) Figure 9 As shown.
[0035] refer to Figure 10 As shown, the upper needle moves back, transferring the loop to the lower needle.
[0036] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
