Description

Flat knitting machine Technical Field The application relates to the field of weaving equipment, in particular to a flat knitting machine. Background The flat knitting machine is used for forming the fabric by mutually stringing the yarns in a loop-forming mode, so that the fabric has good crease resistance and softness, the knitted fabric is pulled downwards by the corresponding pulling mechanism, the loop is kept tensioned on one hand, the knitted fabric is convenient to remove on the other hand, the general pulling mechanism is provided with a heavy object, the heavy object cannot realize the adaptive adjustment of the pulling force, and the pulling force is easy to be overlarge. For this reason, some existing pulling mechanisms start to have a function of placing an excessive pulling force, for example, a segmented pulling device of a knitting machine for processing a sweater with the publication number CN218321838U, the fabric is wound on the silica gel sleeve, and when the pulling force applied to the fabric by the silica gel sleeve is excessive, the friction force provided by the damping block inside the silica gel sleeve is insufficient to drive the silica gel sleeve to continue to rotate at this time, so that the silica gel strip cannot rotate along with the continuous rotation of the rotating shaft. Aiming at the related technology, a shaft sleeve and a transmission mechanism for transmitting motor power are required to be arranged between two adjacent silica gel sleeves, so that a larger distance exists between the two adjacent silica gel sleeves, and then each part of one end of the fabric in the weft direction cannot be effectively pulled, so that the condition of insufficient pulling of the whole fabric is easy to occur. Disclosure of Invention In order to effectively and fully pull each part of the fabric in the weft direction, the application provides a flat knitting machine. The flat knitting machine provided by the application adopts the following technical scheme. The utility model provides a flat knitting machine, includes the flat knitting machine main part of weaving into fabric with the yarn, flat knitting machine main part lower part can dismantle and be connected with the frame plate, the frame plate is equipped with rotatable pivot and drives pivot pivoted pivot motor, the coaxial grafting of pivot has the branch revolving loop of one row of several and supplies the fabric to coil, coaxial rotation connection between two adjacent branch revolving loops, the pivot tip is equipped with the axle end plate that supplies a branch revolving loop to rotate to be connected, the pivot corresponds the equal fixedly connected with of every branch revolving loop a set of several uide bushing, equal sliding connection has the piece that supports that can butt in branch revolving loop inner wall in every uide bushing, the pivot is equipped with the pressure regulating mechanism who forces the piece butt in branch revolving loop inner wall. By adopting the technical scheme, each branch swivel can correspondingly pull one position of one end of the fabric in the weft direction, so that each part of the fabric in the weft direction can be effectively pulled, and the fabric is pulled more fully. Optionally, the pressure regulating mechanism includes the interior pole of grafting in the pivot, locates the several round platform piece of interior pole, locates the frame plate and drives the interior pole jar of interior pole along pivot axis direction removal, and the circumference inclined plane of every round platform piece all butt is in the piece of supporting in corresponding a set of uide bushing. By adopting the technical scheme, the movement of the round table block can push the movement of the supporting block so as to change the pressure between the supporting block and the branch rotating ring, thereby being better suitable for the requirements of different types of fabrics on the maximum traction force. Optionally, the supporting block comprises a sleeve block supporting the round platform block, an inserting block inserted into the sleeve block and capable of supporting the split rotary ring, and an inserting block spring arranged on the sleeve block and forcing the inserting block to be far away from the sleeve block. By adopting the technical scheme, the friction force between the insert block and the branch swivel can be adjusted more finely. Optionally, the sleeve block opening is fixedly connected with a limit column with an end inserted in the insert block. Through adopting above-mentioned technical scheme for the inserted block is difficult to break away from in the cover piece, so when putting into the corresponding pivot of interior pole, the difficult butt in branch swivel of inserted block, put into the back, round platform piece removes so that the inserted block can the butt in branch swivel. Optionally, the sleeve block is abutted to one end side surface of the round table b
