Description

Technical Field

[0001] This utility model relates to an edge-expanding device in the field of fishing net machine technology. Background Technology

[0002] Fishing net machines can only weave a limited area of ​​net at a time. When large-area nets are needed, multiple nets often need to be manually spliced ​​together. However, because the nets woven by the machine do not have sufficient thread ends at the edges, the thread ends must be spliced ​​first during the later manual splicing process. This increases the workload for workers, increases the splicing time, and reduces the production efficiency of the finished net. Utility Model Content

[0003] The purpose of this invention is to provide an edge-expanding device for a fishing net machine, which can lengthen the fishing line at the edge when the fishing net is being woven, so that it can be directly spliced ​​during later processing without the need for manual splicing of the line ends, saving time and effort and improving the production efficiency of fishing net forming.

[0004] To achieve the above objectives, this utility model provides an edge-expanding device for a fishing net machine, including an edge-expanding transmission mechanism connected to an edge-expanding swing mechanism. The edge-expanding swing mechanism is provided with an edge-expanding claw and is mounted on a hook angle iron.

[0005] Compared with the prior art, the beneficial effect of this utility model is that after the fishing line passes through the edging claw, it is wrapped around the hook. The edging transmission mechanism drives the edging swing mechanism to swing back and forth, so that the fishing line is pulled by the edging claw while it is being knotted on the hook. In this way, the fishing line is stretched at the same time. After the fishing net is woven, there will be a longer stretch of line at the edge. This allows the two sides of the fishing net to be spliced ​​together later without the need to add an extra stretch of fishing line, saving time and effort and improving the production efficiency of fishing net forming.

[0006] As a further improvement of this utility model, the edge-expanding transmission mechanism includes a main shaft, on which an edge-expanding cam is sleeved. The edge-expanding cam is matched with a shank bearing, which is installed at one end of the edge-expanding swing arm. A ball roller bearing is installed in the middle of the edge-expanding swing arm, which is assembled with a fulcrum pin. The fulcrum pin is fixedly connected to a mounting angle iron, which is set on the wall plate of the fishing net machine. The other end of the edge-expanding swing arm is connected to the edge-expanding swing mechanism.

[0007] In this way, the main shaft of the fishing net machine is driven to rotate by the motor, which causes the edging cam to rotate. The protruding part of the cam will intermittently touch the shank bearing during the continuous rotation, causing the edging swing arm to swing back and forth around the pivot pin through the bearing, thereby driving the edging mechanism to move back and forth.

[0008] As a further improvement of this utility model, the edge-expanding swing arm mechanism includes a connecting rod. One end of the connecting rod is connected to the other end of the edge-expanding swing arm via a joint bearing. The other end of the connecting rod is connected to one end of a movable angle iron via a joint bearing. The edge-expanding claw is mounted on the movable angle iron, and the movable angle iron is located on the top of the hook angle iron.

[0009] The connecting rod moves back and forth under the action of the lateral arm, which in turn pulls the moving angle iron back and forth, causing the lateral claw to pull the fishing line to one side, thus pulling out more slack in the fishing line. In this way, after the fishing net is woven, there will be an extra section of line at the edge of the net, which makes it easier to splice with other fishing nets.

[0010] As a further improvement of this utility model, the edge-expanding claw includes a body, the upper part of which is machined with two wire claws, with a wire-passing gap between the wire claws, and the tip of the wire claws is machined with a horizontal hook.

[0011] In this way, the fishing line passes through the gap between the line claws, and the horizontal hook reduces the distance at the end of the gap, thus preventing the fishing net line from coming off the hook during the pulling process.

[0012] As a further improvement of this utility model, a limiting angle iron is provided for the horizontal side of the lower part of the movable angle iron. The vertical side of the limiting angle iron is bolted to the hook angle iron, and the horizontal side of the limiting angle iron is attached to the upper surface of the horizontal side of the movable angle iron.

[0013] This way, the horizontal edge of the limiting angle iron presses against the horizontal edge of the moving angle iron, preventing the moving angle iron from flipping over when moving back and forth, thus ensuring the stability of the moving angle iron during the movement process.

[0014] As a further improvement of this utility model, one expansion claw is provided at each end of the movable angle iron.

[0015] This allows the ends of the lines on both sides of the fishing net to be stretched, making it easier to splice the net later. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-3 The shown is a rim-expanding device for a fishing net machine, including an rim-expanding transmission mechanism connected to an rim-expanding swing mechanism. The rim-expanding swing mechanism is provided with an rim-expanding claw 4 and is mounted on a hook angle iron 8.

[0021] The edge-expanding transmission mechanism includes a main shaft 9, on which an edge-expanding cam 10 is sleeved. The edge-expanding cam 10 is matched with a shank bearing 11. The shank bearing 11 is installed at one end of the edge-expanding swing arm 2. A ball roller bearing 13 is installed in the middle of the edge-expanding swing arm 2. The ball roller bearing 13 is assembled with a fulcrum pin 12. The fulcrum pin 12 is fixedly connected to a mounting angle iron. The mounting angle iron is set on the wall plate of the fishing net machine. The other end of the edge-expanding swing arm 2 is connected to the edge-expanding swing mechanism.

[0022] The edge-expanding swing arm 2 mechanism includes a connecting rod 3. One end of the connecting rod 3 is connected to the other end of the edge-expanding swing arm 2 via a joint bearing 1. The other end of the connecting rod 3 is connected to one end of the movable angle iron 6 via a joint bearing 1. The edge-expanding claw 4 is mounted on the movable angle iron 6, and the movable angle iron 6 is located on the top of the hook angle iron 8.

[0023] The edge-expanding claw 4 includes a body 14. Two wire claws 15 are machined on the upper part of the body 14, with a wire-passing gap 16 between them. The tips of the wire claws 15 are machined with horizontal hooks 17. A limiting angle iron 7 is fitted to the lower horizontal edge of the movable angle iron 6. The vertical edge of the limiting angle iron 7 is bolted to the hook angle iron 8, and the horizontal edge of the limiting angle iron 7 rests against the upper surface of the horizontal edge of the movable angle iron 6. One edge-expanding claw 4 is provided at each end of the movable angle iron 6.

[0024] In this invention, the fishing line 5 passes through the line gap 16 of the edging claw 4 and then wraps around the hook. The main shaft 9 of the fishing net machine is driven to rotate by the motor, causing the edging cam 10 to rotate. The protruding part of the cam will intermittently touch the shank bearing 11 during the continuous rotation, causing the edging swing arm 2 to swing back and forth around the pivot pin 12 through the bearing.

[0025] The connecting rod 3 moves back and forth under the drive of the expanding arm 2, thereby pulling the moving angle iron 6 back and forth. This causes the expanding claw 4 to periodically pull the fishing line 5 to one side, thus pulling out more excess fishing line 5. At the same time as the expanding claw 4 pulls the fishing line 5, the hook also weaves the fishing net. As the fishing line 5 is wrapped and knotted on the hook, it is pulled by the expanding claw 4. In this way, after the fishing net is woven, there will be a longer excess line at the edge. This allows the two sides of the fishing net to be spliced ​​together later without the need to add an extra piece of fishing line 5, saving time and effort and improving the production efficiency of fishing net forming.

[0026] During the process of the expansion claw 4 pulling the fishing line 5, the horizontal hook 17 reduces the gap at the upper end of the line passage 16, thus preventing the fishing net line from coming off the hook during the pulling process; at the same time, the horizontal edge of the limiting angle iron 7 presses on the horizontal edge of the moving angle iron 6, so that the moving angle iron 6 will not flip over when moving back and forth, thus ensuring the stability of the moving angle iron 6 during the movement.

[0027] This invention allows the fishing line 5 at the edge to be stretched during the weaving of the fishing net, so that it can be directly spliced ​​during the later processing without the need for manual splicing of the line ends, saving time and effort and improving the production efficiency of fishing net forming.

[0028] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
