Description

Technical Field

[0001] The invention relates to the field of flat knitting machines, in particular to a three-system flat knitting machine. Background Art

[0002] Among the existing knitting machines, the more common one is a double-system knitting machine, that is, two sets of cam systems are arranged on a cam bottom plate, such as Chinese patents CN202809165U, CN201354397Y, etc.

[0003] There are also three-system horizontal knitting machines, that is, three groups of cam systems are set on a cam base plate, each group of cam systems has the same structure, and two needle selection systems are used as a unit. A knitting system and a transfer system are set in the two needle selection systems, so that the three groups of cam systems include three knitting systems, three transfer systems and six needle selection systems. Such as Chinese patents CN201268764Y, CN202945414U, CN109468738B, etc.

[0004] The three-system flat knitting machine adopting this structure has a relatively complex structure, a heavy machine head and a low operating efficiency.

[0005] The inventor discovered through research that when three sets of triangle systems are used for weaving, their structure can be optimized to improve weaving efficiency and reduce the burden on the machine head, which led to the creation of this case. Summary of the invention

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A three-system flat knitting machine comprises a cam base plate and three cam systems arranged on the cam base plate from left to right, wherein the left cam system is a first transfer system, the middle cam system is a knitting system, and the right cam system is a second transfer system.

[0008] Further settings are:

[0009] A set of needle selection units is correspondingly arranged below each set of cam systems.

[0010] The first transfer system is only used for transferring stitches and does not include a knitting function. The first transfer system includes a transfer cam and a receiving cam.

[0011] The knitting system is only used for knitting and does not include a loop transfer function. The knitting system includes an upper Zhongshan triangle and a lower Zhongshan triangle. A density triangle is arranged on each side of the upper Zhongshan triangle. A clearing triangle is arranged below the density triangle, and starting triangles are arranged on both sides of the lower Zhongshan triangle.

[0012] The weaving includes full mesh weaving and half mesh weaving.

[0013] The second transfer system is only used for transferring stitches and does not include a knitting function. The second transfer system includes a transfer cam and a receiving cam.

[0014] Each needle selection unit is mainly composed of a needle selector and a needle selection cam.

[0015] In the weaving system, the upper Zhongshan triangle and the lower Zhongshan triangle form a weaving channel.

[0016] In the knitting system, at least one of the needle raising triangles on both sides of the lower Zhongshan triangle is movable.

[0017] In the knitting system, the needle raising triangles on both sides of the lower Zhongshan triangle are movable.

[0018] The needle cleaning cam can be selected as a movable or fixed needle cleaning cam.

[0019] In the stitch transfer system, the needle transfer cam and the needle receiving cam are arranged at intervals, or the needle transfer cam and the needle receiving cam are arranged closely.

[0020] A set of density triangles may or may not be provided on both sides of the transfer system.

[0021] No density triangles are provided on the two sides of the circle transfer system.

[0022] The beneficial effects of the present invention are:

[0023] The three-system flat knitting machine of the present invention has three systems, the middle system only includes the knitting system, and the systems on the left and right sides only include the loop transfer system. Through the structural setting of the knitting system and the loop transfer system, the three systems independently realize the functions of loop transfer, knitting, and loop transfer, which greatly simplifies the structure of the flat knitting machine, reduces the weight of the machine head, and improves the operating efficiency. At the same time, the structure of the loop transfer system is further simplified, and the setting of the density triangle in the loop transfer system is cancelled. The needle raising triangle and the needle clearing triangle adopt a movable design, which can enable the flat knitting machine to realize more patterns and functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 The figure is a schematic structural diagram of an embodiment of the present invention.

[0025] Figure 2 It is a schematic structural diagram of another embodiment of the present invention. DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-Figure 2As shown, a three-system flat knitting machine includes a cam base plate 5, and three cam systems arranged sequentially from left to right on the cam base plate 5. Specifically, with reference to the needle selection area below, from left to right, based on the area where every two needle selectors 41 are located, it is divided into three cam systems: left, middle, and right (refer to the vertical dotted lines in the figure).

[0028] The three triangular systems are:

[0029] The first transfer system 1 on the left side only realizes the transfer function and does not include the knitting function, and includes the transfer cam 11 and the receiving cam 12.

[0030] The middle weaving system 2: only realizes the weaving function (including full-mesh weaving and half-mesh weaving), and does not include the loop transfer function. The weaving system includes an upper Zhongshan triangle 21 and a lower Zhongshan triangle 22. A density triangle 23 is arranged on both sides of the upper Zhongshan triangle 21. Below the density triangle 23 is a needle clearing triangle 25, and on both sides of the lower Zhongshan triangle 22 are needle raising triangles 24.

[0031] The second stitch transfer system 3 on the right side only realizes the stitch transfer function and does not include the knitting function, and includes a transfer cam 31 and a receiving cam 32 .

[0032] A set of needle selection units 4 is correspondingly arranged below each set of cam systems, and there are three sets of needle selection units in total. Each set of needle selection units 4 is mainly composed of two sets of needle selectors 41 and a plurality of needle selection cams 42 .

[0033] The needle selection unit 4 is used to select the knitting needles in the needle plate and push them to the height required for work (such as middle position, high position, zero position, etc.). The triangle system, such as the circle transfer system and the weaving system, has a track for the operation of the knitting needles. The shape of the above track and the operation mode of the knitting needles are known in the art unless otherwise specified in the present invention.

[0034] In the weaving system, the upper Zhongshan cam 21 and the lower Zhongshan cam 22 form a weaving channel.

[0035] At least one of the needle raising cams 24 on both sides of the lower Zhongshan cam 22 is movable. Preferably, the needle raising cams 24 on both sides of the lower Zhongshan cam 22 are movable. The movable type means that the cam can move up and down relative to the cam bottom plate, and correspondingly, the fixed type means that the cam is fixed relative to the cam bottom plate.

[0036] The needle cleaning cam 25 can be selected as a movable or fixed needle cleaning cam.

[0037] The stitch transfer system (1, 3) realizes the functions of stitch transfer and stitch connection by the cooperation between the stitch transfer cam and the stitch connection cam. The stitch transfer cam and the stitch connection cam can be closely arranged (such as Figure 1As shown, the needle transfer cam and the needle receiving cam are controlled by one layer of stitches. The needle transfer cam and the needle receiving cam can be arranged at intervals (such as Figure 2 As shown, the transfer cam and the receiving cam are controlled by two layers of stitches).

[0038] A set of density triangles may or may not be provided on both sides of the transfer system (1, 3). Figure 1 In the embodiment of the present invention, a set of density triangles 23 is provided on each side of the transfer system (1, 3). Figure 2 In the embodiment, no density triangles are provided on both sides of the transfer system, thereby further simplifying the structure of the flat knitting machine.

[0039] The innovation of the present invention is:

[0040] (1) In a conventional three-system flat knitting machine, the structures of the three systems are the same, and each system includes an independent knitting system and a loop transfer system. In the three-system flat knitting machine of the present invention, the middle system only includes the knitting system, and the systems on the left and right sides only include the loop transfer system. By setting the structures of the knitting system and the loop transfer system, the three systems independently realize the functions of loop transfer, knitting, and loop transfer, which greatly simplifies the structure of the flat knitting machine, reduces the weight of the machine head, and improves the operating efficiency.

[0041] (2) The structure of the circle transfer system is further simplified, and the setting of the density triangle in the circle transfer system is cancelled.

[0042] (3) The needle raising cam and needle clearing cam are designed to be movable, which can enable the flat knitting machine to achieve more patterns and functions.

[0043] The above are only some specific embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any non-substantial changes made to the present invention shall be deemed as an infringement of the protection scope of the present invention.
