Description

Die lift device for super large high-speed rope braiding machine

technical field

The invention relates to a braiding machine, in particular to a die opening lifting device of a super-large high-speed cable braiding machine.

Background technique

The die opening lifting device of the existing rope braiding machine cannot be lifted automatically, but only manually.

Now the cable braiding machine has a gantry, and a connecting block (23-5) is welded on the top of the gantry; there is a circular hole on the connecting block, and the wire passing plate shaft (23-6) is inserted into the hole. There is a hole on the side, and screws (23-4) are installed inside to fix the shaft of the wire-passing plate. The threading plate (23-1) is fixed with a nut under the shaft of the wire-passing plate. There is a circular hole in front of the threading plate (23-1). It is used to place the wire-passing die (23-2). There are screws (23-3) on the outside of the round hole of the threading plate (23-1) to fix the wire-passing die (23-2). This thread-passing die (23-2) is an integral structure, and neither the thread-passing die (23-2) nor the threading plate (23-1) can be opened. When replacing the thread-passing die (23-2), it is necessary to Cut off the braided rope, and then unscrew the screw that fixes the wire-passing die (23-2) to replace the wire-passing die (23-2); Manually loosen the screws on the side of the connecting block, and adjust the position of the wire die opening (23-2) before fixing it. If the knitting effect of the adjusted position is not good, you need to repeat the above actions and adjust again until the adjustment is qualified, which is very inconvenient.

The existing rope braiding die lift device has the following problems: manually adjusting the position of the braiding die and the braiding angle, the adjusted position of the braiding die and the braiding angle have large errors, resulting in poor quality of the braided cable. , because there is no guardrail on the braiding machine, the work risk factor of the staff is high; when the ropes of different thicknesses need to be braided, the ropes being braided must be cut, and the braiding die can be woven normally after replacing the braiding die. This leads to the waste of braided cables, resulting in slow braiding speed and low braiding efficiency.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a super-large high-speed rope braiding machine die opening lifting device, which solves the problem that the braiding die opening of the prior art rope braiding machine needs to be manually adjusted in height, and the rope must be removed when weaving ropes of different thicknesses. The problem that the weaving die can only be replaced by cutting.

The purpose of the present invention is achieved as follows: the die lift device includes: a lifting gear, an output shaft of a reducer, a spring retaining ring for the shaft, a rack cover, a guide groove, a rack, a hexagon socket head screw, a wire passing plate , reducer, gear cover, reducer fixing plate and over-line die;

The lifting gear is sleeved on the output shaft of the reducer and is limited by an elastic retaining ring; the reducer is fixed on the fixing plate of the reducer, the reducer drives the lifting gear to rotate through the flat key, and the lifting gear meshes with the rack to drive the rack to rise and fall; The strip is installed in the guide groove, the guide groove limits the left and right position of the rack, and the rack cover is installed in front of the guide groove; the guide groove is locked on the fixing plate of the reducer with screws; the top of the rack cover is locked with screws with a gear cover , used for safety protection and dust prevention; the lower end of the rack is fixed in the square hole of the wire-passing plate with a hexagon socket head screw;

There is a wire pass die in the circular hole at the front end of the wire pass plate, which is used for positioning the braided wire.

The front end of the wire-passing plate is a circular hole, and the circular hole is composed of two semicircles, one of which is the opening of the movable wire-passing plate. There is a locking groove on the other end of the opening of the wire-passing plate. One end of the locking knob is hinged to the fixed semicircular opening through a pin shaft, and the other end is stuck in the locking groove of the opening of the movable wire-passing plate. Loosen the locking knob to open it. The movable semicircle opening of the wire board.

The wire-passing die is composed of two semicircles.

Two positioning rods are installed in the two elongated holes at the rear of the wire-passing plate. The two positioning rods are worn on the rotating shaft. The two positioning rods take the rotating shaft as the rotation center and move in the elongated holes of the wire-passing plate. The positioning rod is the most There is an induction coil at the bottom, a small retaining ring is set on the induction coil, the screw above the small retaining ring is connected with the screw above the wiring board by a tension spring, a switch seat is installed behind the wiring board, and the micro switch is locked in the switch seat with a screw superior.

The beneficial effect is that because the above scheme is adopted, when starting to knit, lift the wire-passing die to the knitting point to start knitting, and the induction loop is brought up by the knitting wire and separated from the micro switch; When the knitting point falls, the induction loop is pulled up by the tension spring and contacts with the micro switch, and the knitting machine stops to avoid the phenomenon that the spindle is wound around the yarn and the yarn is knotted.

The wire-passing die mouth is changed from manual adjustment to the current motor-driven lift, and the position of the wire-passing die mouth can be changed by pressing a button; when weaving ropes of different thicknesses, there is no need to cut the rope. Unscrew the locking knob to open the wire-passing plate, take out a set of two semi-circular wire-passing dies, replace with a set of required two semi-circular wire-passing dies, then close the wire-passing plate and tighten Tighten the knob, that is, the replacement is successful; at the same time, the lower induction device also effectively prevents the accident of the machine.

The invention solves the problem that the braiding die opening of the prior art rope braiding machine needs to be manually adjusted in height, and the rope must be cut to replace the braiding die when weaving ropes of different thicknesses; the object of the present invention is achieved.

Advantages: The weaving die mouth of the rope braiding machine can be raised and lowered electrically, which avoids the phenomenon of the spindle winding yarn and the yarn knotting, and effectively prevents accidents. At the same time, the ropes of different thicknesses can be directly replaced without cutting the ropes. The braiding die mouth avoids the waste of braided cables; improves the positioning accuracy of the braiding angle, and has high braiding quality and efficiency.
