Description

Technical Field

[0001] The invention relates to the technical field of safety net braided wire cutting, in particular to a safety net braided wire cutting machine and a cutting process thereof. Background Art

[0002] A safety net refers to a protective net structure installed underneath or on the side of a building to ensure construction safety during high-altitude construction or high-altitude equipment installation. It can effectively prevent the fall of high-altitude construction workers and the fall of high-altitude objects. The safety net is composed of a net body, side ropes, tie ropes and tendon ropes, and the net body is a diamond or square structure woven from net ropes. A large amount of braided wire is needed in the process of weaving the safety net. When producing the braided wire, the finished braided wire needs to be wound into rolls through a winding device, and the braided wire needs to be cut after each set of wire winding is completed. Therefore, a safety net braided wire cutting machine is needed to complete this process.

[0003] However, the existing safety net braided wire cutting machine still has certain defects when in use;

[0004] A safety net braided wire cutting machine proposed in application number CN202021404372.8 includes a bracket, four legs are fixedly connected to the bottom of the bracket, a first motor is fixedly installed on the front of the left side of the bracket through a frame, the output end of the first motor is rotatably connected to a conveying mechanism through a rotating shaft, a second motor is fixedly installed on the rear of the left side of the bracket through a frame, the output end of the second motor passes through the bracket and extends the inside of the bracket and is fixedly connected to a wire reel, a cutting assembly is arranged between the conveying mechanism and the wire reel and on the bracket, a guide assembly is arranged between the cutting assembly and the conveying mechanism and on the bracket, and the cutting assembly includes a support plate. In actual use, the following problems still exist:

[0005] 1. During the cutting process of the safety net braided wire cutting machine in the application, the braided wire is easily deformed when it is squeezed and cut by the cutting component, which will cause the braided wire cut by the cutting component to be uneven in length and the cutting surface to be uneven, thereby reducing the cutting effect of the safety net braided wire cutting machine;

[0006] 2. When the braided wire is wound by the safety net braided wire cutting machine in the application, although the braided wire can be evenly wound on the take-up drum through the guide assembly, the guide assembly and the take-up drum need to be driven by a separate drive structure, which will cause a waste of drive resources. At the same time, there is also a phenomenon of reduced operational convenience when unloading the wound wire roll.

[0007] In view of this, we conducted in-depth research on the above issues, which led to the present case.

In the process of the upper cutting knife and the lower cutting knife moving toward each other for cutting, the squeezing and positioning mechanism will be driven to first squeeze and position the two ends of the braided wire, thereby further avoiding deformation of the braided wire during squeezing by the upper cutting knife and the lower cutting knife, thereby improving the cutting smoothness and cutting effect of the safety net braided wire cutting machine.

[0038] 2. When the braided wire is wound on the wire drum, the servo motor can not only drive the wire drum to rotate to realize winding, but also synchronously drive the wire spreading mechanism to perform reciprocating motion through the transmission belt, so as to facilitate the evenly dispersed winding of the braided wire on the wire drum, which not only improves the structural linkage between the wire winding and wire spreading mechanisms, but also improves the winding uniformity of the safety net braided wire cutting machine. The setting of the connecting mechanism can facilitate the rapid disassembly and assembly of the wire drum, thereby improving the convenience of unloading the wire coil after winding.
