Description

Technical Field

[0001] The utility model belongs to a glove machine component, in particular to a glove machine thread cutting mechanism and a movable hook knife. Background Art

[0002] The glove machine will change the line and change the position of the knitting during the knitting process. When changing the line or changing the position of the knitting, the yarn that has just been knitted needs to be clamped, and after the yarn re-enters the knitting, the yarn is cut between the yarn clamping point and the yarn loop that has been re-woven. The traditional glove machine yarn cutting method is to set up multiple clamping mechanisms on the outside of the needle plate knitting area to clamp the yarn, and then cut the yarn after the yarn re-enters the knitting by moving the scissors mechanism or setting a scissors mechanism on the outside of the clamping mechanism. This method of cutting the wire leaves a longer yarn head on the glove, which requires subsequent yarn head shortening. The mobile scissor cutting method also requires a special yarn cutting process, which reduces the production efficiency of the equipment. Utility Model Content

[0003] The utility model aims to solve the defects of the existing glove machine yarn cutting method that the yarn ends are relatively long and a special yarn cutting process is required, and to provide a glove machine thread cutting mechanism which has a relatively short yarn ends and can complete the yarn cutting during the knitting process of the machine head.

[0004] To this end, the utility model adopts the following technical scheme: a thread trimming mechanism of a glove machine, comprising a movable hook knife and a fixed scissor blade, characterized in that the thread trimming mechanism also includes a hook knife insert installed on a needle plate of the glove machine; the needle plate is provided with a plurality of insert mounting grooves arranged along the length direction to form a knitting needle mounting area, and a yarn clamping mechanism is provided on at least one side of the knitting needle mounting area in the length direction of the needle plate; a hook knife insert mounting groove is provided on the needle plate between the knitting needle mounting area and the yarn clamping mechanism, a knitting needle insert or a hook knife insert is inserted in an insert mounting groove adjacent to the hook knife insert mounting groove, a knitting needle insert is inserted in other insert mounting grooves, and the corresponding insert mounting grooves in the insert mounting grooves are inserted. The two adjacent knitting needle inserts or the adjacent knitting needle inserts and the hook knife inserts are matched to form a knitting needle slideway, and the knitting needles driven by the machine head to slide and complete the hooking and weaving are accommodated in the knitting needle slideway; the hook knife insert is inserted into the hook knife insert installation groove, and the hook knife insert in the hook knife insert installation groove and the knitting needle insert or the hook knife insert in the insert installation groove are matched to form a hook knife slideway, and the movable hook knife is accommodated in the hook knife slideway, and the fixed scissor blade is installed between the movable hook knife and the yarn clamping mechanism or the movable hook knife and the adjacent knitting needles, and the movable hook knife slides in the hook knife slideway, and the hooking part of the rear side of the movable hook knife head hooks the thread and cooperates with the front side of the fixed scissor blade head to achieve thread cutting. After the yarn is woven, it is brought from the weaving area in the knitting needle installation area to the yarn clamping mechanism by the yarn mouth, and the yarn is clamped by the yarn clamping mechanism, and the thread cutting mechanism cuts the yarn near the knitting needle installation area. When the yarn rejoins the weaving, the yarn mouth sends the yarn to the weaving area, and after the yarn starts to be weaved, the thread cutting mechanism cuts the yarn. After two thread cuttings, short yarns clamped by the yarn clamping mechanism will be generated.

[0005] As a supplement and improvement to the above technical solution, the utility model also includes the following technical features.

[0006] Preferably, the thread trimming mechanism further comprises a fixed scissor blade support seat mounted on the needle plate of the glove knitting machine, the fixed scissor blade is supported and installed via a rotating shaft on the fixed scissor blade support seat, and the fixed scissor blade is supported by the rotating shaft and can swing.

[0007] Preferably, a spring shoulder is provided on the fixed scissor blade support seat, the spring shoulder is located on one side of the fixed scissor blade, and a spring is provided between the spring shoulder and the fixed scissor blade. The front side of the blade head of the fixed scissor blade is supported against the movable hook knife by the elastic force of the spring, thereby improving the tightness of the cooperation between the rear side of the movable hook knife and the fixed scissors and improving the shearing effect.

[0008] The movable hook knife is driven to slide by the machine head that drives the knitting needles using the same mechanism as that of driving the knitting needles.

[0009] The movable hook knife is driven to slide by a hook knife linear driving mechanism.

[0010] The hook cutter linear drive mechanism comprises a motor, which is connected to a mechanism for converting rotary motion into linear motion, and the mechanism is connected to the movable hook cutter.

[0011] The line hooking part at the rear side of the movable hook knife head and the front side of the fixed scissor blade head are both provided with cutting edges.

[0012] A movable hook knife suitable for the thread cutting mechanism, a groove is formed on one side of the thin-sheet-shaped blade body of the movable hook knife in the width direction, so that the blade body is divided into a blade body, a blade rod and a blade head which are connected as one body in the length direction from back to front, the bottom of the groove is the blade rod, and the front side wall of the groove serves as a thread hooking part, and its characteristic is that the width of the blade head gradually decreases from the back to the front from the side with the groove to the other side, forming a yarn guiding inclined surface, so that the yarn on the yarn mouth is always located on the yarn guiding inclined surface during the movement of the yarn mouth, and will not be entangled on the bottom side of the blade body opposite to the guiding inclined surface, so that the short yarn after two thread cuttings will not be hung on the hook knife of the wire insertion clamping mechanism, and can be sucked away by the yarn head cleaning mechanism.

[0013] The utility model can achieve the following beneficial effects: a thread cutting mechanism composed of a thread hooking mechanism at the rear side of a movable hook knife head and cooperating with the front side of a fixed scissor blade head is arranged at a position close to the knitting needle and the yarn clamping mechanism; the thread cutting mechanism is uniformly driven by a machine head for driving the knitting needle, and no special thread cutting process is required, and the remaining yarn head is shorter, which can significantly improve the glove production efficiency and reduce the labor cost of glove production; and a yarn guide inclined surface with a gradually decreasing width from the back to the front from one side with the groove to the other side is arranged on the movable hook knife head, so that the yarn head cleaning effect is good.
