Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, specifically to a needle bed structure for a computerized flat knitting machine. Background Technology

[0002] A computerized flat knitting machine is a double-needle plate-latch weft knitting machine. Its cam mechanism acts like a set of planar cams. The needle feet can enter the grooves of the cams, and by moving the cams, the needles are forced to move up and down rhythmically within the needle grooves of the needle plate. Through the actions of the needle hook and the needle latch, the yarn is knitted into fabric. During the upward movement of the needle, the loops gradually exit the needle hook, the needle latch opens, and the loops are hooked onto the needle bar. During the downward movement of the needle, the needle hook catches newly placed yarn and pulls it, bending it into a loop. Simultaneously, the existing loops exit the needle hook, and the new loops pass through the old loops, connecting with them in series. Numerous loops are interconnected to form the knitted fabric.

[0003] Chinese Patent Announcement No. CN202359300U discloses a novel needle bed structure for a computerized flat knitting machine. This design increases the movement space of the spring needles by adding notches on the needle bed. While maintaining the elasticity of the protrusions on the spring needles, it allows the spring needle feet to have appropriate bending and deformation space, thereby improving the elasticity and service life of the spring needles. When the protrusions of the spring needles contact the tail of the needle-lifting plate, the elasticity can be completely transferred to the tail of the needle-lifting plate. This prevents the needle pins from moving downwards under external force, thus avoiding needle collision.

[0004] However, the following defects still exist in the specific implementation process: the needle bed structure uses a single needle bed method for knitting, which makes it impossible to knit some fabrics with complex patterns, and the knitting efficiency is poor.

[0005] Based on this, this utility model designs a needle bed structure for a computerized flat knitting machine to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-7 A computerized flat knitting machine needle bed structure includes two support plates 1. The two support plates 1 are fixedly connected to a reinforcing plate 2 at their close ends. The upper ends of the two support plates 1 are fixedly connected to a needle bed mechanism 3. A control mechanism 4 is slidably connected inside the needle bed mechanism 3.

[0032] In this embodiment of the utility model, the needle bed mechanism 3 is supported by the cooperation of two support plates 1 and a reinforcing plate 2, which ensures the stability of the needle bed during use. The control mechanism 4 cooperates with the needle bed mechanism 3 to control the use of the needle bed according to the predetermined settings, so as to weave high-quality fabrics.

[0033] In some embodiments, as Figure 2-4 As shown, in a preferred embodiment of the present invention, the control mechanism 4 includes two head sliders 41. Each of the two head sliders 41 is fixedly connected to a slide bar 42 at one end that is far apart from each other. Each of the two head sliders 41 is fixedly connected to a head assembly 43 on its inner surface. Each of the two head assemblies 43 is fixedly connected to a brush assembly 44 on its outer surface. Each of the two head assemblies 43 is fixedly connected to two connecting arc plates 45 at the part that is close to each other.

[0034] The brush assembly 44 includes a connecting plate 441, a positioning groove 442 is provided on the outer surface of the connecting plate 441, a fixing clip 443 is fixedly connected to the upper end of the connecting plate 441, and a brush body 444 is fixedly connected to the inner surface of the fixing clip 443.

[0035] The head assembly 43 includes a head plate 431. The outer surface of the head plate 431 is fixedly connected to the inner surface of the connecting plate 441. The ends of the two head plates 431 that are close to each other are fixedly connected to the front and rear ends of the two connecting arc plates 45 respectively. Two connecting pieces 432 are fixedly connected to the inner surface of the head plate 431. The lower ends of the two connecting pieces 432 are fixedly connected to a needle-raising triangle plate 433. A needle-lifting triangle plate 434 is fixedly connected to the inner surface of the head plate 431.

[0036] In this embodiment of the invention, two head sliders 41 and two slide bars 42 are used as the driven source. By applying an external driving force, the two head components 43 can slide simultaneously along the inner surface of the two head guide rails 32 with the cooperation of the two head sliders 41 and the two slide bars 42. This allows the head plate 431 to move together with the starting triangle plate 433 and the needle lifting triangle plate 434 to a predetermined position. The needle lifting triangle plate 434 is used to push the needle component 34 at the predetermined position upward during the knitting process. The starting triangle plate 433 is used to lift the needle component 34, thus starting the knitting process. During the movement of the head plate 431, the brush component 44 is also moved together. Under the action of the brush body 444, the lint balls accumulated in the brush groove 332 can be cleaned away, which can effectively avoid the phenomenon of needle lifting failure and improve the quality of the fabric.

[0037] In some embodiments, as Figure 5-7 As shown, in a preferred embodiment of the present invention, the needle bed mechanism 3 includes a needle bed guide rail 31, the lower end of which is fixedly connected to the upper ends of two support plates 1, two machine head guide rails 32 are fixedly connected to the inner surface of the needle bed guide rail 31, the outer surfaces of two slide bars 42 are slidably connected to the inner surfaces of the two machine head guide rails 32 respectively, and two needle bed assemblies 33 are fixedly connected to the inner surface of the needle bed guide rail 31, and a plurality of needle assemblies 34 are slidably connected inside the two needle bed assemblies 33.

[0038] The needle bed assembly 33 includes a needle bed plate 331, with the inner surface of the needle bed plate 331 fixedly connected to the outer surface of the needle bed guide rail 31. Brush grooves 332 are formed on the outer surface of the needle bed plate 331, and the inner surfaces of the two brush grooves 332 are slidably connected to the outer surfaces of the two brush bodies 444 respectively. Two gripping grooves 333 are formed on the outer surface of the needle bed plate 331, and a plurality of needle grooves 334 are formed on the outer surface of the needle bed plate 331.

[0039] The needle assembly 34 includes knitting needles 341. The outer surfaces of several knitting needles 341 are slidably connected to the inner surfaces of several needle grooves 334. A reset shaft 342 is rotatably connected to the inner surface of the knitting needles 341. A needle tongue 343 is fixedly connected to the outer surface of the reset shaft 342. A spring 345 is fixedly connected to the right end of the knitting needles 341. A push groove 344 is opened at the lower end of the knitting needles 341.

[0040] In this embodiment of the invention, by utilizing the cooperation between the starting triangle plate 433 and the push groove 344, when the starting triangle plate 433 slides to the desired starting position, the knitting needle 341 can be pushed upwards at an angle, allowing it to slide along the inner surface of the needle groove 334. Then, by utilizing the action of the lifting triangle plate 434, the knitting needle 341 can be raised to its highest point, so that the knitting needles 341 on both the front and rear sides can complete the looping and gathering actions of the knitting yarn with the cooperation of the spring plate 345, the reset pivot 342, and the needle tongue 343. By controlling the movement of the machine head plate 431, the knitting needles 341 in different positions can be used, thus completing the knitting process of the fabric.

[0041] Working principle: When using a computerized flat knitting machine for fabric knitting, an external drive source can drive the two head assembly 43 to slide simultaneously along the inner surface of the two head guide rails 32 with the cooperation of the two head sliders 41 and the two slide bars 42. This allows the head plate 431 to move together with the needle-raising triangle plate 433 and the needle-lifting triangle plate 434 to a predetermined position. The needle-raising triangle plate 433, in its predetermined position, cooperates with the push groove 344 to lift the needle 341 obliquely upward, causing it to slide along the inner surface of the needle groove 334. Then, using the action of the needle-lifting triangle plate 434, the needle can be... When needle 341 is raised to its highest point, the needles 341 on both sides can complete the looping and gathering of the yarn with the cooperation of spring 345, reset shaft 342 and needle tongue 343. By controlling the movement of the head plate 431, the needles 341 in different positions can be used to complete the knitting process. During the movement of the head plate 431, the brush assembly 44 will also move together. Under the action of the brush body 444, the lint balls accumulated in the brush groove 332 can be cleaned away, which can effectively avoid the phenomenon of needle raising failure and improve the quality of the fabric.
