[0010] The second technical problem to be solved by the present invention is to provide a method for punching holes in aquaculture nets using the device.

[0011] In order to solve the above problems, the technical solution adopted by the method of using the device to punch holes in aquaculture nets is as follows: the method comprises the following steps:

[0012] The first step is to pull the net frame forward

[0013] The net pulling hook moves downward, the top of the net pulling hook is located below the mesh, the net pulling motor drives the net pulling driving wheel to rotate, and the net pulling frame moves forward along the net pulling track;

[0014] Step 2: Pull the net

[0015] The net-pulling hook moves upward, the net-pulling hook clamps the weft wire in front, the net-pulling motor drives the net-pulling driving wheel to rotate, and the net-pulling frame pulls the net backward along the net-pulling track;

[0016] Step 3: Cutting off the ends of the weft

[0017] When the net-pulling hook hooks the weft wire in front and pulls the net, the end of the weft wire happens to be located below the cutting knife at the lower end of the cutting cylinder. At this time, the cutting cylinder is pressed down, and the cutting knife cuts off the end of the weft wire of the mesh;

[0018] The fourth step is to cut the weft between the adjacent warp threads in the middle to form a large mesh.

[0019] According to the mesh specifications, when the weft between two adjacent warps needs to be cut, after the rear of the mesh and the two ends of the weft to be cut are cut, while the net-pulling frame moves forward, the weft-cutting cylinder drives the movable weft-cutting cutter to move down, so that the weft-clip slot of the movable weft-cutting cutter is flush with the position of the weft, and when the net-pulling hook hooks the front weft, the weft to be cut is just stuck in the weft-clip slot, and while the net is being pulled, the weft-cutting cylinder drives the movable weft-cutting cutter to move up, and when the weft reaches the position of the two fixed weft-cutting cutters, the fixed weft-cutting cutters cut the weft of the two adjacent warps to form a large mesh;

[0020] Step 5: Punch holes on the edge of the mesh to form mesh gaps

[0021] When the position where the mesh needs to be punched reaches the position of the edge punching bottom knife, the net pulling hook just hooks the weft wire in front. While the net pulling frame pulls the mesh backward, the top rod of the edge punching cylinder drives the edge punching upper knife to press down, and the edge punching bottom knife cuts off the warp and weft wires that need to be punched.

[0022] As a further improvement, the method comprises the following steps:

[0023] The first step is to pull the net frame forward

[0024] The net pulling hook moves downward, the top of the net pulling hook is located below the mesh, the net pulling motor drives the net pulling driving wheel to rotate, and the net pulling frame moves forward along the net pulling track;

[0025] Step 2: Pull the net

[0026] The net-pulling hook moves upward, the net-pulling hook clamps the weft wire in front, the net-pulling motor drives the net-pulling driving wheel to rotate, and the net-pulling frame pulls the net backward along the net-pulling track;

[0027] Step 3: Cutting off the ends of the weft

[0028] When the net-pulling hook hooks the weft wire in front and pulls the net, the end of the weft wire happens to be located below the cutting knife at the lower end of the cutting cylinder. At this time, the cutting cylinder is pressed down, and the cutting knife cuts off the end of the weft wire of the mesh;

[0029] The fourth step is to cut the weft between the adjacent warp threads in the middle to form a large mesh.

[0030] According to the mesh specifications, when the weft between two adjacent warps needs to be cut, after the rear of the mesh and the two ends of the weft to be cut are cut, while the net-pulling frame moves forward, the weft-cutting cylinder drives the movable weft-cutting cutter to move down, so that the weft-clip slot of the movable weft-cutting cutter is flush with the position of the weft, and when the net-pulling hook hooks the front weft, the weft to be cut is just stuck in the weft-clip slot, and while the net is being pulled, the weft-cutting cylinder drives the movable weft-cutting cutter to move up, and when the weft reaches the position of the two fixed weft-cutting cutters, the fixed weft-cutting cutters cut the weft of the two adjacent warps to form a large mesh;

[0031] Step 5: Punch holes on the edge of the mesh to form mesh gaps

[0032] When the mesh needs to be punched and reaches the position of the edge punching bottom knife, the net pulling hook just hooks the weft wire in front. While the net pulling frame pulls the mesh backward, the top rod of the edge punching cylinder drives the edge punching upper knife to press down, and the edge punching bottom knife cuts off the warp and weft wires that need to be punched.

[0033] Step 6: Punch holes in the middle of the mesh to form extra large mesh holes

[0034] When the mesh reaches the position where punching is required and reaches the position of the middle punching bottom knife, the net pulling hook just hooks the weft wire in front. While the net pulling frame pulls the mesh backward, the push rod of the middle punching cylinder drives the middle punching upper knife to press down, and the middle punching bottom knife cuts off the warp and weft wires that need to be punched.

A method for punching a net using the net punching device for aquaculture net welding machine according to claim 1, 2 or 3, characterized in that: The method comprises the following steps: The first step is to pull the net frame forward The net pulling hook moves downward, the top of the net pulling hook is located below the mesh, the net pulling motor drives the net pulling driving wheel to rotate, and the net pulling frame moves forward along the net pulling track; Step 2: Pull the net The net-pulling hook moves upward, the net-pulling hook clamps the weft wire in front, the net-pulling motor drives the net-pulling driving wheel to rotate, and the net-pulling frame pulls the net backward along the net-pulling track; Step 3: Cutting off the ends of the weft When the net-pulling hook hooks the weft wire in front and pulls the net, the end of the weft wire happens to be located below the cutting knife at the lower end of the cutting cylinder. At this time, the cutting cylinder is pressed down, and the cutting knife cuts off the end of the weft wire of the mesh; The fourth step is to cut the weft between the adjacent warp threads in the middle to form a large mesh. According to the mesh specifications, when the weft between two adjacent warps needs to be cut, after the rear of the mesh and the two ends of the weft to be cut are cut, while the net-pulling frame moves forward, the weft-cutting cylinder drives the movable weft-cutting cutter to move down, so that the weft-clip slot of the movable weft-cutting cutter is flush with the position of the weft, and when the net-pulling hook hooks the front weft, the weft to be cut is just stuck in the weft-clip slot, and while the net is being pulled, the weft-cutting cylinder drives the movable weft-cutting cutter to move up, and when the weft reaches the position of the two fixed weft-cutting cutters, the fixed weft-cutting cutters cut the weft of the two adjacent warps to form a large mesh; Step 5: Punch holes on the edge of the mesh to form mesh gaps When the position where the mesh needs to be punched reaches the position of the edge punching bottom knife, the net pulling hook just hooks the weft wire in front. While the net pulling frame pulls the mesh backward, the top rod of the edge punching cylinder drives the edge punching upper knife to press down, and the edge punching bottom knife cuts off the warp and weft wires that need to be punched.

While the net pulling frame pulls the mesh backward, the top rod of the edge punching cylinder drives the edge punching upper knife to press down, and the edge punching bottom knife cuts off the warp and weft wires that need to be punched. Step 6: Punch holes in the middle of the mesh to form extra large mesh holes When the mesh reaches the position where punching is required and reaches the position of the middle punching bottom knife, the net pulling hook just hooks the weft wire in front. While the net pulling frame pulls the mesh backward, the push rod of the middle punching cylinder drives the middle punching upper knife to press down, and the middle punching bottom knife cuts off the warp and weft wires that need to be punched.
