Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The cloth cutting mechanism for the warp knitting winding device is arranged between a warp knitting machine and the winding mechanism and is used for orderly cutting the wound cloth and the cloth on the warp knitting machine as shown in figures 1 to 5. Specifically, the cloth cutting mechanism includes a cutting assembly 100 mounted on the winding mechanism, the cutting assembly includes a first guide bar 130 disposed on the winding mechanism, the first guide bar extends along a width direction of the cloth, a first traveling part 110 capable of traveling along an axial direction of the first guide bar is mounted on the first guide bar, and an upward cutting blade 120 is disposed on the first traveling part. When the cloth is wound, the first travelling part is started and moves along the axial direction of the first guide rod, and the cutting knife 120 cuts the cloth neatly in the moving process.

Meanwhile, two second guide rods 300 are arranged above the winding mechanism in a straddling manner, the two second guide rods are respectively arranged at two ends of the winding mechanism, and the two ends of the second guide rods are connected with the frame 200 for fixing. A second traveling part 400 capable of moving along the axial direction of the second guide rod is installed on the second guide rod 120, a lifting part 500 is installed below the second traveling part, the lifting part can adopt a pneumatic telescopic cylinder or a hydraulic telescopic cylinder, and an electric clamping jaw 600 capable of moving up and down under the driving of the lifting part is connected to the end part of the lifting part. The motorized clamping jaw 600 mainly comprises two clamping jaws 620 and a body 610 for driving the two clamping jaws to open and close. It should be noted that, the clamping jaw is internally provided with a concave semicircular groove, the diameter of the groove is the same as that of the winding shaft, and when the two clamping jaws are folded, the winding shaft to be replaced is clamped by the folded clamping jaws in a rotatable manner. A first drive roller 630 is rotatably mounted in one of the jaws 620, the first drive roller 630 being in tangential contact with the gripped take-up shaft surface when the jaws grip the take-up shaft. At the same time, a drive section 640 is also mounted on the jaw to which the first drive shaft 630 is mounted, and is in driving connection with the first drive roller to drive the take-up shaft to rotate in the jaw.

The specific driving part 640 includes a first motor 641 mounted on the clamping jaw, and a second driving roller 643 rotatably mounted on the clamping jaw 620, wherein an output shaft of the first motor is in driving connection with the second driving roller through a conveyor belt 642. The first motor is driven to rotate to drive the winding shaft clamped in the clamping jaw 620 to rotate.

In addition, a tension adjusting assembly 800 is provided between the warp knitting machine and the lifting part, and includes an adjusting roller 820 hung on the fabric, and a set of guide frames 810 provided at both ends of the adjusting roller. The two ends of the regulating roller are in sliding fit and extend into the guide groove in the guide frame so as to float up and down when the tension of the cloth changes. In most cases, the cloth discharging speed of the warp knitting machine is synchronous with the cloth collecting speed of the collecting mechanism, so that the regulating roller often falls on the lower part of the guide groove.

Finally, a cloth turning assembly 700 is installed between the lifting part 500 and the cutting assembly 100, and includes a cloth turning rod 730 extending in the width direction of the cloth, both ends of which are connected to a support frame 720 hinged to the ground and connected to a second motor 710 in a driving manner. The second motor drives the support frame 720 to turn over, and then drives the cloth turning rod 730 to turn over to be abutted with the winding shaft clamped by the clamping jaws.

Working principle: after the cloth is wound, the related actions of the warp knitting machine and the winding mechanism are suspended. And after the cloth is cut by the cutting mechanism, one end of the cloth falls down and is lapped on the cloth turning rod under the action of gravity, and then the second motor drives the cloth turning rod to turn over and be abutted with a winding shaft clamped by the electric clamping jaw, and the free end of the cloth is wrapped on the winding shaft under the driving of the cloth turning rod. And then the winding shaft is driven to rotate by the driving part, the rotating winding shaft winds the whole free end of the cloth, and the cloth is firmly wrapped on the winding shaft. After the above steps are completed, the cloth turning mechanism is reset, the lifting part drives the electric clamping jaw to rise to be higher than the winding mechanism, then the second walking part drives the winding shaft to move along the direction of the winding mechanism, and in the moving process, the tension adjusting assembly 800 exists, so that the cloth has a stretched allowance. When the winding shaft moves to the position above the winding device, the electric clamping jaw loosens the winding shaft, and the winding shaft falls on the winding mechanism. The replacement of the take-up reel is also completed at the same time. The braiding and winding of the cloth can be implemented again only by restarting the winding mechanism and the warp knitting machine.

In the above embodiment, the weight of the adjusting roller is smaller than that of the winding shaft, so as to prevent the winding shaft from being pulled out again by the adjusting roller after being placed on the winding mechanism, thereby affecting the normal winding.
