Description
Technical Field
The invention relates to the technical field of flat knitting machines, in particular to a guide pin triangular device suitable for bidirectional knitting of a glove rib part.
Background
There are knitting glove knitting machines of two kinds of forms in the market at present, be applicable to the one-way weaving and two-way weaving to gloves respectively, wherein, the basic theory of operation of one-way weaving is:
when the tubular part main body of the glove is knitted, the needle guide machine head moves from left to right, the needle guide cam device on the back needle guide machine head pushes up the knitting needle on the back needle bed and sucks the yarn in one yarn nozzle to finish a knitting action; correspondingly, when the needle guide machine head moves from right to left, the needle guide cam device in the front needle guide machine head pushes up the knitting needle on the front needle bed and engages the yarn in the same yarn nozzle to finish another knitting action. Therefore, the needle guide head completes a reciprocating action from left to right and then back to left, namely, completes a knitting course, and the yarns are knitted in a single spiral mode by continuously circulating and running.
On the basis, in order to increase the working efficiency, the inventor has a Chinese patent application with patent number CN202210035315.4, disclosing a synchronous knitting mechanism and a knitting method thereof for synchronously knitting front and back heads of a knitting glove machine, in the application, the inventor explains that the front and back heads can respectively feed two paths of yarns in the working process, in the same knitting course, through the staggered arrangement or the side-by-side arrangement of the two heads and reasonably adjusting the descending amplitude of the knitting needles, the forward needle raising and the reverse needle raising can be realized (the forward needle raising generally means that only the needle cam device on the back head guide head pushes up the knitting needles on the back needle bed when the back head guide head moves from left to right, only the needle cam device on the front needle bed pushes up the knitting needles on the front needle bed when the right head moves from left, and the reverse needle raising means that the needle cam device on the front head guide head can also push up the knitting needles on the front needle bed when the back head moves from left to right, the needle guide cam device on the rear needle guide head can push up the knitting needle on the rear needle bed when moving from right to left), so that the fingertips and the finger joints of the knitted gloves can be sewn together, and other knitted courses can be knitted without being sewn together, so that the knitting speed is increased by nearly one time under the condition that the movement speed of the needle guide head is not increased, the productivity is greatly increased, and two paths of yarns in the equipment are jointly knitted in a crossed double-spiral mode.
At present, the structure of the guide pin triangle device in the conventional knitting glove knitting machine on the market is basically only two, and the working mode of the guide pin triangle device in knitting the rib part is simply described as follows:
the first method comprises the following steps: only has the forward needle raising function and does not have the reverse needle raising function. In the positive direction needle raising process, the running track of the needle foot is as follows: the knitting machine is characterized in that the knitting machine ascends along the inclined plane of the rubber string raising cam until the highest point, then descends to the bottom of the rubber string raising cam along the inclined plane of the rubber string density cam, ascends to the highest point along the inclined plane of the forward raising cam, descends along the cam track, descends to the position of the forward density cam, and then descends to the bottom of the rubber string density cam along the inclined plane of the forward density cam continuously, so that the knitting of the yarns after the rubber strings are knitted in one direction is completed.
And the second method comprises the following steps: meanwhile, the knitting glove machine has the functions of forward needle raising and reverse needle raising, and is called a jacquard glove machine or a computerized flat knitting machine in the industry. If the reverse needle raising is performed after the forward needle raising in the same knitting course, the moving track of the needle stitch is as follows: after passing through the bottom of the rubber band density triangle, the movement is carried out through the bottom of the reverse density triangle.
Although the second working mode can realize reverse needle raising, the descending amplitude of the knitting needle which enters the elastic yarn is inevitably increased, and further the elastic yarn is broken or the size and the tightness of the rib part of the glove are uncontrollable.
Therefore, the industrial knitting glove knitting machine generally does not implement the working mode of reverse needle raising when knitting rib parts, and even if the reverse needle raising is required, the following modes are adopted:
1. the knitting of the elastic thread is not carried out in the same knitting course where the reverse needle raising is carried out (the trade term is called tuck);
2. if the knitting of the elastic yarn needs to be considered in the reverse needle raising process, in order to prevent the elastic yarn from being broken or influence the knitting quality of a rib part, the reverse density triangle can only be greatly increased, so that the bottom of the reverse density triangle and the bottom of the elastic yarn density triangle reach the same height, and the descending amplitude of a knitting needle which is eaten into the elastic yarn cannot be changed by the reverse density triangle. However, this results in a high knitting density of the yarns in the knitted course, and a normal knitting cannot be achieved.
In summary, in a common glove knitting machine or flat knitting machine, both reverse needle raising knitting and elastic yarn knitting cannot be normally realized in the same knitting course of the knitting rib part, so that the glove knitting machine or flat knitting machine cannot be well applicable to a processing mode of bidirectional synchronous knitting, and cannot be well matched with a processing mode of improving the glove processing efficiency.
Disclosure of Invention
In order to solve the problems, the invention provides a guide pin triangular device suitable for bidirectional knitting of a rib part of a glove.
The technical scheme adopted by the invention is as follows: a guide pin cam device suitable for bidirectional knitting of a glove rib part is used for controlling the lifting motion of a stitch of a knitting needle in a front needle bed or a back needle bed in a needle groove, the guide pin cam device is installed on the inner side of a guide pin machine head, at least one machine head driving module used for driving two guide pin machine heads to respectively carry out reciprocating linear displacement on the front needle bed and the back needle bed is arranged on a flat knitting machine, in addition, in the working process of the machine head driving module, the two guide pin machine heads are provided with two relative position states of front-back symmetrical arrangement and front-back staggered arrangement, the left-to-right running direction of the guide pin machine head connected with the back needle bed in a sliding way and the right-to-left running direction of the guide pin machine head connected with the front needle bed in a sliding way are set as a forward direction, the left-to-right running direction of the guide pin machine head connected with the front needle bed in a sliding way and the right-to-left running direction of the guide pin machine head connected with the back needle bed in a sliding way are set as a reverse direction, two guide pin aircraft noses are set up and are reciprocated once respectively on front needle bed or back needle bed and form a knitting course, guide pin triangle device includes:
the mounting plate is fixedly mounted on one side of the guide pin machine head;
the guide pin assembly is arranged on the mounting plate and comprises a rubber band guide pin structure and a yarn guide pin structure; in one knitting course, the guide pin assembly on the same guide pin machine head has two working states of forward needle raising and reverse needle raising, and the two working states are finished once;
in the process of the needle guide machine head running along the forward direction, the yarn needle guide structure passes through the front needle bed or the rear needle bed before passing through the rubber band needle guide structure to finish the forward needle raising once, and in the process of the forward needle raising, the needle guide assembly is used for being matched with a knitting needle to knit in yarn and then in rubber band yarn;
and in the reverse needle raising process, the guide needle assembly is used for matching with a knitting needle to only knit yarns and not to knit elastic yarns.
To assist understanding, the following briefly describes the role played by the guide pin cam device in a glove knitting machine or flat knitting machine:
the needle guiding cam device is like a group of plane cams, the stitch of a knitting needle can enter the groove channel of the cam, the cam is moved, the knitting needle is forced to do regular lifting motion in the needle groove of the front needle bed or the back needle bed, and the yarn can be knitted into knitted fabric by matching the yarn feeding mechanism with the yarn nozzle to complete the action of the needle hook and the needle latch. In the ascending process of the knitting needle, the coil gradually withdraws from the needle hook, the needle latch is opened, and the withdrawing needle latch is hung on the needle rod; during the descending process of the knitting needle, the needle hook hooks the yarn which is newly laid and draws and bends the yarn into a coil, meanwhile, the original coil is pulled out of the needle hook, the new coil penetrates through the old coil and is connected with the old coil in series, and the coil strings knitted by a plurality of knitting needles are mutually connected to form the knitted fabric.
It should be noted that flat knitting machine generally includes the frame, aircraft nose drive module installs in the frame, still install yarn mouth drive assembly in the frame, yarn group drive assembly includes the guide rail that a plurality of mutual intervals set up, be equipped with at least a pair of yarn mouth on the single guide rail and correspond a plurality of driving motor that the yarn mouth carries out round trip displacement on the guide rail alone respectively, each yarn mouth is all through independent driving motor control in order to in forward set-up or reverse set-up in-process, the action of knitting the yarn into the knitted fabric is accomplished to corresponding cooperation knitting needle, above-mentioned action all can be controlled by the control mechanism who installs in the frame.
If the equipment can also carry out reverse needle raising when the glove rib part is knitted, the needle stitch passes through the bottom of the rubber string density triangle during the forward needle raising knitting process and then continues to move through the bottom of the reverse density triangle (in this case, the descending amplitude of the needle which has already inserted the rubber string is increased).
When a guide pin triangular device on the market is used for raising a needle in a forward direction, elastic yarns are knitted in by matching with a knitting needle, and then yarns are knitted in. This application has overturned the principle that other knitting glove knitting machines weave into the yarn behind the elastic cord earlier when a knitting course, the innovative elastic cord that weaves into behind the yarn with weaving into earlier in a knitting course, so that in the knitting course of weaving rib portion, it is the bottom of rethread elastic cord density triangle behind the bottom through reverse density triangle earlier during forward set-up, consequently, when reverse set-up, the condition that can increase the descending amplitude that has eaten into the elastic cord knitting needle just also does not exist, just can not lead to the fracture of elastic cord or the emergence of gloves rib position size and the uncontrollable condition of elasticity yet.

If it is desired to perform reverse needle raising while knitting the rib of the glove, the needle foot passes the bottom of the elastic thread density cam 83 during the forward needle raising knitting and then continues to move through the bottom of the reverse density cam 86 (this results in a larger descent of the needle which has already engaged the elastic thread).
When the needle guiding cam device 8 on the market starts to knit in the positive direction, elastic yarns are knitted in by matching with knitting needles firstly, and then yarns are knitted in. This application has overturned the principle that other knitting glove knitting machines weave into the yarn behind the elastic cord earlier when a knitting course, the innovative elastic cord that weaves into behind the yarn with weaving into earlier in a knitting course, so that in the knitting course of weaving rib portion, it is the bottom of rethread elastic cord density triangle 83 behind the bottom through reverse density triangle 86 earlier during forward set-up, consequently, when reverse set-up, the condition that can increase the descending amplitude that has eaten into the knitting needle of elastic cord just also does not exist, just can not lead to the fracture of elastic cord or the uncontrollable condition of gloves rib position size and elasticity to take place yet.
