Background
At present, most of drawing devices of knitting machinery adopt roller devices, but the roller devices aim at simultaneously drawing the whole fabric, selective drawing of the fabric cannot be realized, and the roller devices have great limitation particularly on a full-forming machine, and a rubber layer in the roller has certain loss factor, so that the fabric is easy to deform when being drawn to a certain degree, and the rejection rate is increased.
Some knitting machines are additionally provided with a rake type traction device, the rake type traction device consists of a plurality of traction mechanisms which are arranged oppositely, and selective traction on the fabric can be realized according to the specific weaving requirement of the fabric. The traction mechanism comprises a gripper and a lifting seat which drives the gripper to move up and down, the gripper comprises a needle seat and a plurality of needles, the gripper needs to continuously enter and exit the fabric, if the needles on the gripper assembly are damaged, the fabric is easily grabbed, the fabric cannot be grabbed, the traction force is unstable, and the rejection rate of the fabric is increased. Therefore, the protective plate is arranged at the front end of the gripper, so that the gripper and the knitted fabric can be protected, and the gripper can enter and exit the knitted fabric more smoothly. However, when the fabric is woven in different patterns, the thickness of the fabric can be changed, the existing guard plates are made of rigid materials, the distance between the two guard plates is fixed, the too large distance between the two guard plates can be generated when the fabric is pulled, the length of the gripper extending out of the guard plates is too short, the wool fabric is easy to grab when the fabric is pulled, or the distance between the two guard plates is too small, the thickened fabric with complicated patterns cannot be pulled, and the normal work of a knitting machine is influenced. Moreover, the prior guard plate is of a short plate structure, only covers the part of the gripper, and the part of the lifting seat below the gripper is still exposed outside.
Disclosure of Invention
The utility model aims at providing a gripper subassembly among knitting machine pulling device can draw the fabric of different thickness when weaving.
Therefore, the technical scheme of the utility model is that: a gripper assembly in a traction device of a knitting machine comprises a protective plate, a gripper and a fixed seat, wherein the gripper and the protective plate are arranged on the fixed seat, and the protective plate is positioned in front of the gripper; the gripper consists of a needle seat and a plurality of needles, and a plurality of needle grooves for the needles to enter and exit are arranged above the guard plate; the method is characterized in that: the guard plate is provided with at least one longitudinal elastic groove.
Furthermore, a connecting strip is arranged above the fixed seat, and the top end of the guard plate is buckled on the connecting strip after being bent inwards.
Furthermore, a lifting seat is further arranged below the gripper, and the lower portion of the guard plate extends downwards to the front of the lifting seat.
The utility model discloses vertically set up many elastic tanks on the backplate for the backplate is horizontal elasticity, can produce certain elastic deformation volume, makes the interval of two backplates can change. When the fabric drawing device works, the guard plates arranged oppositely are in a state of touching or slightly clamping the fabric, so that the grabs can smoothly enter and exit the fabric, and the fabric drawing device plays an auxiliary role in drawing the fabric. When the thickness of the fabric is increased, the guard plates are slightly extruded by the fabric to generate deformation, namely, the two guard plates are passively separated, the distance is increased, after the thickness of the fabric is reduced, the fabric has no acting force on the guard plates, the two guard plates automatically reset through elasticity, the distance is reduced, and the traction action is smoothly completed.
The utility model discloses a backplate below is fixed, and the top is after inwards buckling, detains on the connecting strip, but the connecting strip slightly floats relatively. When the guard plate is extruded by the fabric, the top end of the guard plate can move towards the connecting strip, and the distance between the two guard plates is increased. The backplate downwardly extending has increased the whole length of backplate for the backplate can protect the grabhook and the lift seat of grabhook below.
The utility model discloses be fit for carrying out the tractive to the knitted fabric of certain thickness scope, the backplate needs to have elasticity, has certain elastic deformation volume, and like this when the knitted fabric of tractive certain limit thickness, interval between the backplate can freely adjust at any time according to fabric thickness, accomplishes the tractive action smoothly. When a plurality of groups of traction mechanisms work together, a single group of guard plates can be locally changed, the guard plate interval at the complex pattern part is increased and the guard plate interval at the single-thin pattern part is unchanged, and the traction action on the fabric is jointly completed.
