Knitting process for meshes of circular knitting machine
Technical Field
The invention relates to a mesh weaving process of a circular knitting machine.
Background
The mesh fabric is a fabric commonly used in the footwear and clothing industry, and is a fabric with mesh holes. In recent years, with the continuous development of the technique of flying-weaving shoe uppers, the application of mesh cloth on shoe uppers is increasing. However, the prior mesh cloth is woven by a flat knitting machine, and the circular knitting machine does not have a weaving process capable of weaving meshes, particularly large meshes.
Disclosure of Invention
The invention aims to provide a mesh weaving process of a circular knitting machine, which can weave meshes, aiming at the defects of the prior art.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a knitting circular knitting machine mesh knitting technology, adopts the two-sided knitting needle circular knitting machine who has knitting way and transfer circuit to weave, its characterized in that: the method comprises the following steps:
firstly, knitting a prepared tissue, wherein the prepared tissue is alternately knitted by adopting a mode of full knitting by an upper knitting needle and full knitting by a lower knitting needle on a plurality of knitting paths;
second, a transfer motion is carried out, after preparing the tissue, a transfer path is adopted for the transfer motion, the transfer motion is carried out between the adjacent front and back upper knitting needles and the adjacent front and back lower knitting needles to form meshes, the front lower knitting needle transfers to the front upper knitting needle, the back upper knitting needle transfers to the back lower knitting needle, or the front upper knitting needle transfers to the front lower knitting needle, and the back lower knitting needle transfers to the back upper knitting needle;
thirdly, performing first hole expanding knitting, wherein one path of knitting path is adopted after the transfer action, knitting is performed in a mode of full knitting of a lower knitting needle on knitting needles except for the lower knitting needle for removing the coil in the transfer action, the upper knitting needle for receiving the coil in the transfer action performs loop knitting, and the lower knitting needle for removing the coil in the transfer action performs tuck knitting;
fourthly, transitional knitting is conducted, and knitting is conducted in a full knitting mode of knitting needles above a knitting path after the first hole expanding knitting;
and fifthly, second hole expanding knitting is adopted, one knitting path is adopted after transition knitting, knitting is carried out in a mode of full knitting of the lower knitting needle at the knitting needles except for the lower knitting needle for removing the loop in the transfer action, loop knitting is carried out at the upper knitting needle for receiving the loop in the transfer action, loop gathering knitting is carried out at the lower knitting needle for removing the loop in the transfer action, and therefore mesh knitting is completed.
The circular knitting machine comprises twelve knitting paths and four transfer paths, one transfer path is inserted into each three knitting paths, and the preparation organization is completed by adopting three knitting paths.
The double-sided circular knitting machine has the functions of moving up and down and moving down, and the function of moving up and down is as follows: transferring the loops on the upper knitting needle to the lower knitting needle through a loop transfer function; the move down up function is: the loop on the lower needle is transferred to the upper needle by means of a transfer function.
The double-sided circular knitting machine has the functions of loop transfer and loop collection.
The invention has the following beneficial effects:
the invention forms mesh by transferring between two upper knitting needles adjacent to each other in front and back and two lower knitting needles adjacent to each other in front and back, and enlarges the mesh by twice reaming and knitting, if a large mesh is to be formed: front lower needles transfer to front upper needles and rear upper needles transfer to rear lower needles, if small meshes are to be formed: the front upper knitting needle transfers the loop to the front lower knitting needle, the back lower knitting needle transfers the loop to the back upper knitting needle, the size of the knitting mesh can be selected according to the requirement, and therefore the mesh knitting of the circular knitting machine is realized.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a weaving principle diagram of the first embodiment of the present invention, and a macro-mesh is woven.
Fig. 2 is a weaving principle diagram of the second embodiment of the present invention, weaving small meshes.
Detailed Description
In the first embodiment, referring to fig. 1, a mesh knitting process of a circular knitting machine is performed by using a sixteen-way double-sided knitting machine, where twelve ways are knitting ways, four ways are transfer ways, that is, one transfer way is inserted into each three knitting ways, the number of the twelve knitting ways is 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, the number of the four transfer ways is 4, 8, 12, 16, and only the first 9 knitting ways are shown in fig. 1.
The embodiment I is used for weaving a large mesh, and the mesh weaving process of the circular knitting machine comprises the following steps:
firstly, preparing tissue by alternately knitting the tissue by adopting a full-needle knitting mode of a knitting needle above knitting paths 1, 2 and 3 and a full-needle knitting mode of a lower knitting needle;
secondly, a transfer motion is carried out, after the tissue is prepared, the transfer motion is carried out by adopting a transfer path 4, the transfer motion is carried out between the adjacent front and rear upper knitting needles D 'and E' and the adjacent front and rear lower knitting needles D, E to form meshes, the front lower knitting needle D is transferred to the front upper knitting needle D ', and the rear upper knitting needle E' is transferred to the rear lower knitting needle E;
thirdly, performing first broaching knitting, knitting by adopting a knitting path 5 in a full knitting mode of a lower knitting needle except a front lower knitting needle D after the transfer action, receiving front upper knitting needles D' of the loops in the transfer action, performing loop knitting, and removing front lower knitting needles D of the loops in the transfer action;
fourthly, transitional knitting, namely knitting by adopting a full knitting mode of knitting needles above a knitting path 6 after the first reaming knitting;
and fifthly, second hole expanding knitting, after the transition knitting, knitting is carried out by adopting a knitting path 7 in a full knitting mode of a lower knitting needle except the front lower knitting needle D, knitting is carried out by a front upper knitting needle D' of the receiving coil in the transfer action, and tucking knitting is carried out by the front lower knitting needle D removing the coil in the transfer action, so that the mesh hole knitting is completed.
The second embodiment is different from the first embodiment in that: the transfer motion adopts a front upper knitting needle D ' to transfer to a front lower knitting needle D, a rear lower knitting needle E to transfer to a rear upper knitting needle E ', the hole expanding knitting at the rear is carried out on the rear upper knitting needle E ' of the transfer motion receiving coil, the lower knitting needle E removing the coil is carried out on the transfer motion to carry out tucking knitting, and therefore the mesh knitting is completed.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
