Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat knitting needles, and in particular to a variable needle spacing needle for computer flat knitting machines. Background Technology
[0002] A computerized flat knitting machine is a type of textile machinery primarily used for knitting sweaters and other knitted fabrics. It is based on the traditional flat knitting machine but incorporates a computer control system. The knitting system of a computerized flat knitting machine controls the movement of the knitting needles through a triangular device at the knitting head, including needle selection and loop shifting. During the knitting process, the yarn is drawn from the yarn bobbin, fed to the knitting needles via yarn guides and other devices, and then knits according to a pre-set pattern and stitch under the precise control of the computer program. For example, when knitting complex jacquard patterns, the computer accurately controls which needles participate in the knitting, which needles perform looping, or which needles remain inactive, based on the pattern data, thus creating a beautiful pattern.
[0003] Traditional knitting needles mostly adopt a fixed length design or adjustable knitting needles. For example, some old-fashioned knitting needles connect the needle head and needle body through a complex mechanical structure. However, adjustment requires the use of various tools to disassemble and reassemble, which consumes a lot of time and effort. This makes the adjustment of the knitting needle very cumbersome. Furthermore, the staff directly judges the length after adjustment, which greatly reduces the efficiency and accuracy of adjusting the knitting needle. In order to address this technical problem, this application proposes a variable needle length knitting needle for computerized flat knitting machines. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a variable needle length for computerized flat knitting machines. By pushing the movable needle head into the needle body and using a locking block 1 to move and lock it among multiple locking blocks 2, the movable needle head can be effectively limited, ensuring its stable position. This facilitates the adjustment of the needle length, avoids the problem of knitting quality being affected by unsuitable length, and greatly improves the efficiency and accuracy of knitting work.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A variable gauge needle for a computerized flat knitting machine includes a needle body. A movable groove is provided at the left end of the needle body. Two locking blocks are fixedly connected to the inner walls of the top and bottom ends of the movable groove. A movable needle head is provided in the movable groove. An interval groove is provided at the right end of the movable needle head. A locking block is fixedly connected to the top and bottom ends of the movable needle head. A needle hook is fixedly connected to the left end of the movable needle head.
[0007] Furthermore, a spring is provided inside the partition groove, with one end of the spring connected to the inner wall of the top end of the partition groove and the other end of the spring connected to the inner wall of the bottom end of the partition groove.
[0008] Furthermore, a notch is provided on the right side of the bottom end of the needle body.
[0009] Furthermore, an observation groove is provided on the top side of the middle end of the needle body.
[0010] Furthermore, a scale line is provided at the middle end of the needle body.
[0011] Furthermore, the second card block is mirrored in arrangement with the first card block, and the distance between each pair of the second card blocks is adapted to that of the first card block.
[0012] Furthermore, a needle tongue is provided at the middle end of the movable needle.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, by pushing the movable needle into the needle body and using the method of the first locking block moving and locking between multiple second locking blocks, the movable needle can be effectively limited, ensuring its stable position. This facilitates the adjustment of the needle length, avoids the problem of affecting the knitting quality due to unsuitable length, and greatly improves the efficiency and accuracy of knitting work.
[0015] 2. In this utility model, the observation groove allows the staff to clearly observe the specific position of the moving needle, making the adjustment process more intuitive. The staff can accurately determine the length of the knitting needle according to the scale line, so as to accurately adjust the knitting needle to the required length. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-3 This utility model provides an embodiment of a variable needle pitch knitting needle for a computerized flat knitting machine, comprising a needle body 1, the right end of the needle body 1 being pointed, and a movable groove 8 being provided at the left end of the needle body 1. The size of the movable groove 8 is larger than that of the movable needle head 2. The top and bottom inner walls of the movable groove 8 are fixedly connected with locking blocks 2 11, which can limit the movable needle head 2. The movable needle head 2 is provided in the movable groove 8. The right end of the movable needle head 2 is provided with a gap groove 7, which allows the right end of the movable needle head 2 to have a certain deformation space. The top and bottom ends of the movable needle head 2 are fixedly connected with locking blocks 10, which can be locked between the two locking blocks 2 11, thereby fixing the movable needle head 2. The left end of the movable needle head 2 is fixedly connected with a needle hook 4.
[0023] Reference Figure 1-3 The spacer 7 contains a spring 9, one end of which is connected to the inner wall of the top of the spacer 7, and the other end of which is connected to the inner wall of the bottom of the spacer 7. The spring 9 applies pressure to the right end of the movable needle 2 towards the top and bottom, thereby improving the stability of the locking block 10 between the two locking blocks 11. A notch 6 is provided on the right side of the bottom of the needle body 1. An observation groove is provided on the top side of the middle end of the needle body 1, allowing the operator to easily observe the position of the movable needle 2. A scale line 5 is provided in the middle of the needle body 1, allowing the operator to more intuitively determine the position of the movable needle 2. The locking blocks 11 are mirror images of the locking blocks 10, and the distance between each pair of locking blocks 11 matches that of the locking blocks 10, allowing the locking blocks 10 to be locked between the two locking blocks 11. A needle tongue 3 is provided in the middle of the movable needle 2.
[0024] Working principle: When the length of the knitting needle needs to be adjusted, by pushing the movable needle 2 into the needle body 1, the locking block 10 located on the top and bottom sides of the right end of the movable needle 2 can move between multiple locking blocks 11, thereby locking it between multiple locking blocks 11, thus limiting the movable needle 2. The observation groove allows the operator to easily observe the position of the movable needle 2, and the length of the knitting needle can be determined by the scale line 5, so that the operator can adjust the knitting needle to the accurate length.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
