For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] As Figures 1-5 shown, an embodiment of the present utility model provides a needle selecting cylinder, which is installed on a fixed shaft 1, and the fixed shaft 1 is installed on an external frame. The needle selecting cylinder includes at least two needle selecting sub-cylinder assemblies 2. The needle selecting sub-cylinder assembly 2 includes a sub-cylinder 21 and a needle selecting block 22 arranged on the outer side wall of the sub-cylinder 21. Specifically, the needle selecting block 22 forms a protrusion through being installed on the outer side wall of the sub-cylinder 21, and then is used in cooperation with a knitting needle through a latch piece, so that the knitting needle rises to a predetermined position. Where the needle selecting block 22 is not installed, the knitting needle does not move. There are a plurality of sub-cylinders 21 in total, and each sub-cylinder 21 can rotate independently and is sleeved on the outer side of the fixed shaft 1. In this way, each sub-cylinder 21 can rotate independently to switch the needle selecting block 22 on its side wall located at the needle selecting position to control the selection of the knitting needle. Therefore, for the needle selecting cylinder composed of a plurality of sub-cylinders 21, by adjusting the rotation angle of each sub-cylinder 21, the position of the needle selecting block 22 thereon is changed. As a result, the relative positions of all the needle selecting blocks 22 on the outer side wall of the entire needle selecting cylinder will change, and there will be many combinations of the needle selecting blocks 22 in the same row, and many kinds of needle selecting block combinations can be formed on the outer side wall of the needle selecting cylinder, forming a variety of needle selecting combinations. The user can adjust the rotation angle of the sub-cylinder correspondingly according to the glove pattern and / or size requirements to be knitted, so that the needle selecting block combination on the needle selecting cylinder meets the processing requirements, and is no longer restricted by the rule that the needle selecting cylinder needs to be replaced every time a different glove pattern and / or glove knitting is carried out, which saves time and effort.

[0033] In this embodiment, during the working process of the needle selecting cylinder, it is necessary to dynamically adjust the rotation angle of each sub-cylinder 21 according to the glove pattern and / or size and the working position during processing, so that the combination of the needle selecting blocks 22 in the uppermost row of the entire needle selecting cylinder for cooperating with the knitting needles meets the processing requirements.

[0034] Certainly, in another embodiment, the rotation angles of the respective sub-cylinders 21 are adjusted in advance according to the glove pattern and / or size to be processed. After the adjustment, the needle selecting combinations of all rows on the entire needle selecting cylinder are determined. During the working process, the needle selecting cylinder rotates as a whole according to the working position for needle selecting work, that is, all the sub-cylinders 21 need to rotate synchronously to work.

[0035] Specifically, the sub-cylinder 21 controls the use of at least one knitting needle. For example, if the sub-cylinder 21 only controls the use of one knitting needle, there are two ways of selecting needles for the sub-cylinder 21. Only one needle selection block 22 is provided for cooperation with the knitting needle, and the remaining angular positions are all non-selected needle positions; if the sub-cylinder 21 controls the use of two knitting needles, there are two positions on the sub-cylinder 21 in the axial direction for installing the needle selection block 22, namely the first position and the second position, corresponding to the control of two knitting needles respectively, and there are four ways of selecting needles. The four placement combinations of the needle selection blocks 22 are distributed along the circumferential direction of the sub-cylinder 21, which are: the needle selection block 22 is set at the first position and the needle selection block 22 is not set at the second position, the needle selection block 22 is not set at the first position and the needle selection block 22 is set at the second position, the needle selection block 22 is set at the first position and the needle selection block 22 is set at the second position, the needle selection block 22 is not set at the first position and the needle selection block 22 is not set at the second position either; if the sub-cylinder 21 controls the use of three knitting needles, there are three positions on the sub-cylinder 21 in the axial direction for installing the needle selection block 22, namely the first position and the second position, corresponding to the control of three knitting needles respectively, and there are eight ways of selecting needles, and so on, as Figure 5 shown. Of course, the above only discloses all the needle selection control methods and the distribution methods of the needle selection blocks 22 on the sub-cylinder 21 when it controls different numbers of knitting needles. However, in the actual design process, it can be designed according to the needs of the designer, and it is not necessary to design all the needle selection methods on the same sub-cylinder 21.

[0036] Among them, the number of knitting needles controlled by each of the above-mentioned sub-cylinders 21 can be the same or different, and it is designed according to the needs of the user. Of course, for more convenient use, in this embodiment, the number of knitting needles controlled by each sub-cylinder 21 is the same.

[0037] Among them, the heights of the needle selection blocks 22 on each sub-cylinder 21 can be partially the same or different, that is, the heights of the needle selection blocks 22 in the same row can be all the same, partially the same or all different, so as to select high and low needles in the corresponding workstations to achieve multi-station needle selection.

[0038] Specifically, as Figure 2 shown, the needle selection sub-cylinder assembly 2 further includes a driving assembly 23 for driving the circumferential rotation of the sub-cylinder 21. The sub-cylinder 21 is provided with an installation cavity 211 coaxial with the fixed shaft 1, and the installation cavity 211 is open at one end along the central axis of the fixed shaft 1. The driving assembly 23 can be installed in the installation cavity 211 from the opening, and the output end of the driving assembly 23 is connected to the side wall of the installation cavity 211, so as to drive the sub-cylinder 21 to rotate. Of course, when all the sub-cylinders 21 need to rotate simultaneously, only the driving assembly 23 needs to be started simultaneously.

[0039] Specifically, in this embodiment, the driving assembly 23 includes a first outer rotor motor 231. The first outer rotor motor 231 is fixedly sleeved on the fixed shaft 1, that is, it cannot move axially along the fixed shaft 1. Fixing plates can be installed on the two outer sides of the first outer rotor motor 231 along the axial direction, and the fixing plates are detachably connected to the fixed shaft 1 through bolts, or they can be limitedly connected by other existing methods. Correspondingly, the outer side wall of the first outer rotor motor 231 is connected to the inner side wall of the installation cavity 211 to form an integral body. Of course, whether they are connected by bolts or limitedly connected by keys, and then the outer side wall of the first outer rotor and the outer side wall of the syringe barrel are connected into an integral body through a connecting plate and bolts, all are acceptable. The fixed shaft 1 plays a supporting role. Driven by the first outer rotor motor 231, the outer part of the first outer rotor motor 231 drives the sub-syringe barrel 21 to rotate. Moreover, the first outer rotor motor 231 is located in the installation cavity 211 and is hidden, which has better aesthetics.

[0040] Specifically, in another embodiment, as Figure 3 shown, the driving assembly 23 includes a rotational driving device 232, a driving wheel 233 and a driven internal gear 234. The rotational driving device 232 can be a motor and can be installed on the fixed shaft 1 through a mounting plate. One end of the driving shaft of the driving wheel 233 is connected to the output shaft of the rotational driving device 232, and the other end is rotatably installed on the inner side wall of the installation cavity 211 through a bearing. The driven internal gear 234 is installed on the inner side wall of the installation cavity 211. The driving wheel 233 meshes with the driven internal gear 234, so that the driven internal gear 234 can be driven to rotate under the drive of the rotational driving device 232, and then drive the sub-syringe barrel 21 to rotate. The sub-syringe barrel 21 is rotatably installed on the fixed shaft 1 through a bearing and is fixed by an external end cover.

[0041] Specifically, in another embodiment, as Figure 4 shown, the sub-syringe barrel 21 is provided as a second outer rotor motor 24. The second outer rotor motor 24 is fixedly sleeved on the fixed shaft 1. The needle selecting block 22 is installed on the outer side wall of the second outer rotor motor 24. The outer rotor motor is directly set as the sub-syringe barrel 21, and the needle selecting block 22 is set on the outer rotor motor, and the overall design is simpler.

[0042] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
