[0002] Fishing gear is a general term for various tools directly used to catch and harvest economic animals in the water. Aquatic products caught in the world using net fishing gear account for more than 80% of the total catch, so net fishing gear is also used more frequently.

[0003] Chinese patent application No. 202021133374.8 discloses a cutting device for the production of net fishing gear, including a workbench, a knife holder and a cutting groove, the middle part of the upper end of the workbench is connected to the knife holder by bolts, the middle part of the bottom end of the knife holder is connected to the hydraulic cylinder by bolts, the bottom end of the hydraulic cylinder is connected to the knife seat by bolts, the bottom end of the knife seat is connected to the cutting knife by bolts, the two sides of the knife holder are formed with sliding grooves, the knife seat and the sliding groove are slidably connected, and the workbench is formed with a cutting groove opposite to the cutting knife. The beneficial effect is that the present invention can ensure the stable movement of the cutting knife, improve the cutting accuracy, and ensure that the incision of the net fishing gear is neat and beautiful by arranging the knife holder, the sliding groove and the cutting groove, and at the same time can reduce the recoil force on the cutting knife during the cutting process, reduce damage, and extend the service life.

[0004] Although the above-mentioned patent has realized the cutting work for the production of net fishing gear, it has the following disadvantages in actual use: 1. Although the unwinding roller for unwinding the net fishing gear can unwind the net fishing gear, it is inconvenient to disassemble and assemble the unwinding roller. When the net fishing gear is used up, it is inconvenient to replace the new net fishing gear;

[0005] 2. When cutting the fishing net, the other side of the fishing net may be lifted up. At this time, when the cutting device is cutting the fishing net, the cutting edge of the cutting knife may be offset.

[0006] 3. Although the device for pulling the fishing net can pull the fishing net, it cannot automatically adjust the cutting length, and the overall use effect is not good. At the same time, the pulling device has a relatively poor fixing effect on the fishing net. Summary of the invention

[0015] Furthermore, the pulling length adjustment mechanism of the net fishing gear includes a second motor, a threaded rod, a second nut block, a fixing frame, an ear plate, a laser displacement transmitter, a controller, a laser displacement receiver and a fixing assembly of the net fishing gear.

[0018] Furthermore, a cutting method for a cutting device for processing a net-shaped fishing gear comprises the following steps:

[0019] S1: When the net fishing gear on the surface of the unwinding roller body is cut, turn on the motor 1, which drives the bidirectional screw to rotate through the output end. The rotation of the bidirectional screw drives the two sets of nut blocks 1 to move away from each other. When the nut block 1 slides, it drives the limit block 1 to slide inside the limit groove 1, thereby improving the stability of the sliding process of the nut block 1. The nut blocks 1 move away from each other, thereby driving the two sets of mounting plates to move away from each other. At this time, the unwinding roller body can be disassembled, and after replacing the new unwinding roller body, turn on the motor 1 to drive the bidirectional screw to rotate in the opposite direction, thereby driving the two sets of nut blocks 1 to move toward each other. When the two sets of nut blocks are close to each other, the two sets of mounting plates are close to each other, thereby fixing the unwinding roller body. When the mounting plates are close to each other, the hexagonal block at the other end of the rotating shaft is driven to insert into the hexagonal groove on the side of the unwinding roller body, thereby ensuring that the unwinding roller body can rotate normally after being fixed. Then, by opening the hydraulic cylinder 1 at the upper end of the gantry, the hydraulic cylinder 1 drives the pressing plate to descend, and the pressing plate descends and drives the cutting knife to descend, thereby cutting the net fishing gear. At the same time, when the pressing plate descends, it drives the slider to slide inside the slide slot, thereby improving the stability of the pressing plate and the cutting knife during the descent process;

[0020] S2: In order to avoid the problem of the net fishing gear being offset during cutting and the problem of the unwinding roller body rotating excessively when the subsequent net fishing gear is pulled, after the net fishing gear is pulled to a suitable position, the positioning frame is driven to rotate by holding the pull handle until the block on the side of the positioning frame is inserted into the slot in the workbench. Before the block is inserted into the slot, the adjustment block inside the adjustment slot is slid. The adjustment block drives the fixing rod to compress the spring and embed it into the workbench. When the block is fully inserted into the slot, the spring rebounds, thereby driving the fixing rod to insert into the fixing hole, so as to fix the positioning frame and position and fix the net fishing gear at the same time.

[0021] S3: put one end of the net fishing gear into the interior of the fixed frame, turn on the second hydraulic cylinder, the second hydraulic cylinder drives the fixed plate to descend so as to fix the net fishing gear, and at the same time, the descent of the fixed plate will drive the second limit block to slide inside the second limit slot, thereby improving the stability of the sliding process of the fixed plate, and then turn on the second motor, the second motor drives the threaded rod to rotate through the output end, the rotation of the threaded rod drives the second nut block to slide, the sliding of the second nut block drives the fixed frame to slide, and when the fixed frame slides, it drives the guide block to slide on the surface of the guide rod, thereby improving the stability of the sliding process of the fixed frame, thereby driving the net fishing gear to be pulled, and when the fixed frame slides, it drives the ear plate to slide, and when the ear plate slides, it drives the laser displacement transmitter to move, thereby changing the distance between the laser displacement transmitter and the laser displacement receiver, after the pulling length of the net fishing gear is set by the controller, when the distance between the laser displacement transmitter and the laser displacement receiver reaches the length set by the controller, the controller receives a signal at this time, and can control the second motor to be turned off, thereby realizing automatic adjustment of the pulling length of the net fishing gear.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a disassembly and assembly mechanism for the unwinding roller, and the arrangement of the mechanism can facilitate the disassembly of the unwinding roller. In this way, after the cutting of the net fishing gear on the surface of the unwinding roller is completed, a new unwinding roller can be conveniently replaced for subsequent cutting work. By arranging a hexagonal block on the side of the rotating shaft and opening a hexagonal groove corresponding to the hexagonal block on the side of the unwinding roller, the fixing effect of the mechanism on the unwinding roller can be improved.

[0024] 2. The present invention provides a mesh fishing gear positioning mechanism, which can facilitate the positioning and fixing of the mesh fishing gear that has just entered the cutting device position, thereby avoiding the problem of the mesh fishing gear being tilted during cutting, resulting in the problem of the mesh fishing gear being offset during cutting.

[0025] 3. The present invention provides a mechanism for adjusting the pulling length of the fishing net, which can facilitate the pulling of the fishing net and control the pulling length of the fishing net. In addition, the fixing effect of the fishing net can be improved by providing a fixing component for the fishing net. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-8 The present invention provides the following technical solutions: a cutting device and a cutting method for processing net fishing gear, comprising a workbench 1, a supporting leg 11 is arranged at the lower corner of the workbench 1, a gantry 7 is arranged at the center position of the upper end of the workbench 1, a hydraulic cylinder 4 is arranged at the upper end of the gantry 7, a pressing plate 5 is arranged at the lower end of the hydraulic cylinder 4, a cutting knife 12 is arranged at the lower end of the pressing plate 5, a giving groove 2 corresponding to the cutting knife 12 is opened at the upper end of the workbench 1, a slider 10 is arranged on the side of the pressing plate 5, a sliding groove 6 corresponding to the slider 10 is opened on the inner wall of the gantry 7, a reeling roller disassembly and assembly mechanism 9 is arranged on one side of the upper end of the workbench 1, a net fishing gear positioning mechanism 8 is arranged at the upper end of the workbench 1 near the reeling roller disassembly and assembly mechanism 9, and a net fishing gear pulling length adjustment mechanism 3 is arranged on the other side of the upper end of the workbench 1.

[0038] The present invention further comprises a reel disassembling and assembling mechanism 9 comprising a bidirectional screw 91, a nut block 92, a motor 93, a mounting plate 96, a rotating shaft 97 and a reel body 98. A motor 93 is arranged at the side edge of the workbench 1, a bidirectional screw 91 is arranged at the output end of the motor 93, two groups of nut blocks 92 are symmetrically arranged on the surface of the bidirectional screw 91, a mounting plate 96 is arranged at the upper end of the nut block 92, a rotating shaft 97 is arranged at the side of the mounting plate 96, and a reel body 98 is arranged at the side of the rotating shaft 97.

[0039] By adopting the above technical scheme, when the net fishing gear on the surface of the unwinding roller body 98 is cut, the motor 93 is turned on, and the motor 93 drives the bidirectional screw rod 91 to rotate through the output end. The rotation of the bidirectional screw rod 91 drives the two groups of nut blocks 92 to move away from each other, and the nut blocks 92 move away from each other, thereby driving the two groups of mounting plates 96 to move away from each other. At this time, the unwinding roller body 98 can be removed and replaced with a new unwinding roller body 98. Then, by turning on the motor 93, it drives the bidirectional screw rod 91 to rotate in the opposite direction, thereby driving the two groups of nut blocks 92 to move closer to each other, and the two groups of nut blocks 92 to move closer to each other drive the two groups of mounting plates 96 to move closer to each other, thereby fixing the unwinding roller body 98.

[0040] In the present invention, the unwinding roller disassembly and assembly mechanism 9 further includes a limit groove 94 and a limit block 95. The limit block 95 is arranged on the side of the nut block 92, and a limit groove 94 corresponding to the limit block 95 is opened inside the workbench 1.

[0041] By adopting the above technical solution, when the nut block 92 slides, it will drive the limiting block 95 to slide inside the limiting groove 94, thereby improving the stability of the sliding process of the nut block 92.

[0042] In the present invention, the unwinding roller disassembly and assembly mechanism 9 further includes a hexagonal block 99 and a hexagonal groove 910. The other end of the rotating shaft 97 is provided with a hexagonal block 99, and the side of the unwinding roller body 98 is provided with a hexagonal groove 910 corresponding to the hexagonal block 99.

[0043] By adopting the above technical solution, when the mounting plates 96 are close to each other, the hexagonal block 99 at the other end of the rotating shaft 97 will be driven to insert into the hexagonal groove 910 on the side of the unwinding roller body 98, thereby ensuring that the unwinding roller body 98 can rotate normally after being fixed.

[0044] When the present embodiment is in use, after the mesh fishing gear on the surface of the unwinding roller body 98 is cut, the motor 93 is turned on, and the motor 93 drives the bidirectional screw rod 91 to rotate through the output end. The rotation of the bidirectional screw rod 91 drives the two groups of nut blocks 92 to move away from each other. When the nut block 92 slides, it drives the limit block 95 to slide inside the limit groove 94, thereby improving the stability of the sliding process of the nut block 92. The nut blocks 92 move away from each other, thereby driving the two groups of mounting plates 96 to move away from each other. At this time, the unwinding roller body 98 can be disassembled, and after replacing the new unwinding roller body 98, the motor 93 is turned on to drive the bidirectional screw rod 91 to rotate in the opposite direction, thereby driving the two groups of nut blocks 9 2 are close to each other, and the two groups of nut blocks 92 are close to each other to drive the two groups of mounting plates 96 to be close to each other, so as to fix the unwinding roller body 98. When the mounting plates 96 are close to each other, the hexagonal block 99 at the other end of the rotating shaft 97 will be driven to insert into the hexagonal groove 910 on the side of the unwinding roller body 98, so as to ensure that the unwinding roller body 98 can rotate normally after being fixed. Then, by opening the hydraulic cylinder 4 at the upper end of the gantry 7, the hydraulic cylinder 4 drives the pressing plate 5 to descend, and the pressing plate 5 descends to drive the cutting knife 12 to descend, so as to cut the net fishing gear. At the same time, when the pressing plate 5 descends, it will drive the slider 10 to slide inside the slide groove 6, so as to improve the stability of the pressing plate 5 and the cutting knife 12 during the descending process.

[0045] Example 2

[0046] The present embodiment is different from the first embodiment in that: the net fishing gear positioning mechanism 8 comprises a block 81, a fixing hole 82, a handle 83, a positioning frame 84, a slot 85 and a positioning frame fixing assembly 86; the upper end of the workbench 1 is provided with a positioning frame 84 near the net fishing gear positioning mechanism 8 through a hinge rotation connection; the upper end of the positioning frame 84 is provided with a handle 83; the other side of the lower end of the positioning frame 84 is provided with a block 81; the side of the block 81 is provided with a fixing hole 82; the upper edge of the workbench 1 is provided with a slot 85 corresponding to the block 81; the side of the slot 85 is provided with a positioning frame fixing assembly 86;

[0047] By adopting the above technical solution, in order to avoid the problem of deviation of the net fishing gear during cutting and the problem of excessive rotation of the unwinding roller body 98 when the net fishing gear is subsequently pulled, after the net fishing gear is pulled to a suitable position, the positioning frame 84 is driven to rotate by holding the pull handle 83 until the block 81 on the side of the positioning frame 84 is inserted into the slot 85 in the workbench 1, and then the positioning frame fixing component 86 and the fixing hole 82 are used to fix the positioning frame 84, and at the same time, the positioning and fixing of the net fishing gear can be achieved.

[0048] The present invention further includes a positioning frame fixing assembly 86 comprising a fixing rod 861, an adjusting block 862, an adjusting slot 863 and a spring 864. A spring 864 is provided inside the side of the slot 85. A fixing rod 861 is provided at the other end of the spring 864. An adjusting block 862 is provided at the side of the fixing rod 861. An adjusting slot 863 corresponding to the adjusting block 862 is provided at the side of the workbench 1.

[0049] By adopting the above technical solution, before the block 81 is inserted into the slot 85, the adjusting block 862 in the sliding adjusting slot 863 is slid, and the adjusting block 862 drives the fixing rod 861 to compress the spring 864 and embed into the workbench 1. When the block 81 is completely inserted into the slot 85, the spring 864 rebounds, thereby driving the fixing rod 861 to insert into the fixing hole 82, so as to fix the positioning frame 84 and simultaneously realize the positioning and fixation of the net fishing gear.

[0050] When the present embodiment is in use, in order to avoid the problem of deviation of the net fishing gear during cutting and the problem of excessive rotation of the unwinding roller body 98 when the subsequent net fishing gear is pulled, after the net fishing gear is pulled to a suitable position, the positioning frame 84 is driven to rotate by holding the pull handle 83 until the block 81 on the side of the positioning frame 84 is inserted into the slot 85 in the workbench 1, and before the block 81 is inserted into the slot 85, the adjustment block 862 in the adjustment slot 863 is slid, and the adjustment block 862 drives the fixing rod 861 to compress the spring 864 and embed it into the workbench 1. When the block 81 is completely inserted into the slot 85, the spring 864 rebounds, thereby driving the fixing rod 861 to insert into the fixing hole 82, so as to fix the positioning frame 84 and position and fix the net fishing gear.

[0051] Example 3

[0052] The present embodiment is different from the first embodiment and the second embodiment in that the net fishing gear pulling length adjustment mechanism 3 comprises a second motor 31, a threaded rod 32, a second nut block 33, a fixing frame 34, an ear plate 35, a laser displacement transmitter 36, a controller 37, a laser displacement receiver 38 and a net fishing gear fixing assembly 39. The second motor 31 is arranged at the center position of the other side of the workbench 1. The output end of the second motor 31 is arranged with a threaded rod 32. The surface of the threaded rod 32 is threadedly connected with a second nut block 33. The upper end of the second nut block 33 is arranged with a fixing frame 34.

The side edge of the gantry 7 is provided with a laser displacement receiver 38 at a position corresponding to the laser displacement transmitter 36. The upper edge of the fixing frame 34 is provided with a controller 37. The inner position of the fixing frame 34 is provided with a net fishing gear fixing assembly 39.

[0053] By adopting the above technical solution, one end of the net fishing gear is placed inside the fixing frame 34, and the net fishing gear is fixed by the net fishing gear fixing component 39, and then the motor 2 31 is turned on, the motor 2 31 drives the threaded rod 32 to rotate through the output end, the threaded rod 32 rotates to drive the nut block 2 33 to slide, and the nut block 2 33 slides to drive the fixing frame 34 to slide, thereby driving the net fishing gear to be pulled, and when the fixing frame 34 slides, it drives the ear plate 35 to slide, and when the ear plate 35 slides, it drives the laser displacement transmitter 36 to move, so that the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 changes. After the pulling length of the net fishing gear is set by the controller 37, when the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 reaches the length set by the controller 37, the controller 37 receives a signal at this time, and can control the motor 2 31 to be turned off, thereby realizing automatic adjustment of the pulling length of the net fishing gear.

[0054] In the present invention, the net fishing gear pulling length adjustment mechanism 3 further includes a guide block 310 and a guide rod 311. The lower end side of the fixing frame 34 is located inside the workbench 1 and is provided with a guide block 310. The guide block 310 is provided inside and penetrates the guide rod 311.

[0055] By adopting the above technical solution, when the fixing frame 34 slides, it will drive the guide block 310 to slide on the surface of the guide rod 311, thereby improving the stability of the sliding process of the fixing frame 34.

[0056] The present invention further provides that the net fishing gear fixing assembly 39 includes a second hydraulic cylinder 391, a second limiting groove 392, a second limiting block 393 and a fixing plate 394. The second hydraulic cylinder 391 is provided at the center of the upper end of the fixing frame 34, the lower end of the second hydraulic cylinder 391 is provided with a fixing plate 394, the side of the fixing plate 394 is provided with a second limiting block 393, and the inner wall of the fixing frame 34 is provided with a second limiting groove 392 corresponding to the second limiting block 393.

[0057] By adopting the above technical solution, when fixing the fishing net, the hydraulic cylinder 391 is turned on, and the hydraulic cylinder 391 drives the fixing plate 394 to descend so as to fix the fishing net. At the same time, the descent of the fixing plate 394 drives the limiting block 393 to slide inside the limiting groove 392, thereby improving the stability of the sliding process of the fixing plate 394.

[0058] When the present embodiment is in use, one end of the net fishing gear is placed inside the fixing frame 34, and the hydraulic cylinder 391 is turned on. The hydraulic cylinder 391 drives the fixing plate 394 to descend so as to fix the net fishing gear. At the same time, the descent of the fixing plate 394 drives the limiting block 393 to slide inside the limiting groove 392, thereby improving the stability of the sliding process of the fixing plate 394. Then, by turning on the motor 31, the motor 31 drives the threaded rod 32 to rotate through the output end. The rotation of the threaded rod 32 drives the nut block 33 to slide. The sliding of the nut block 33 drives the fixing frame 34 to slide. When the fixing frame 34 slides, it drives the guide block 310 on the guide rod 311 When the fixed frame 34 slides, the ear plate 35 will be driven to slide, and when the ear plate 35 slides, the laser displacement transmitter 36 will be driven to move, so that the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 changes. After the pulling length of the net fishing gear is set by the controller 37, when the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 reaches the length set by the controller 37, the controller 37 receives a signal and controls the motor 2 31 to be turned off, thereby realizing automatic adjustment of the pulling length of the net fishing gear.

[0059] The present invention further provides a cutting method for a cutting device for processing a net-shaped fishing gear, comprising the following steps:

[0060] S1: When the net fishing gear on the surface of the unwinding roller body 98 is cut, the motor 93 is turned on. The motor 93 drives the bidirectional screw rod 91 to rotate through the output end. The rotation of the bidirectional screw rod 91 drives the two groups of nut blocks 92 to move away from each other. When the nut block 92 slides, it drives the limit block 95 to slide inside the limit groove 94, thereby improving the stability of the sliding process of the nut block 92. The nut blocks 92 move away from each other, thereby driving the two groups of mounting plates 96 to move away from each other. At this time, the unwinding roller body 98 can be disassembled and replaced with a new unwinding roller body 98. Then, by turning on the motor 93, it drives the bidirectional screw rod 91 to rotate in the opposite direction, thereby driving the two groups of nut blocks 92 to move toward each other. When the two groups of nut blocks 92 are close to each other, the two groups of mounting plates 96 are close to each other, thereby fixing the unwinding roller body 98. When the mounting plates 96 are close to each other, the hexagonal block 99 at the other end of the rotating shaft 97 is driven to be inserted into the hexagonal groove 910 on the side of the unwinding roller body 98, thereby ensuring that the unwinding roller body 98 can rotate normally after being fixed. Then, by opening the hydraulic cylinder 4 at the upper end of the gantry 7, the hydraulic cylinder 4 drives the pressing plate 5 to descend, and the pressing plate 5 descends and drives the cutting knife 12 to descend, thereby cutting the net fishing gear. At the same time, when the pressing plate 5 descends, it drives the slider 10 to slide inside the slide groove 6, thereby improving the stability of the pressing plate 5 and the cutting knife 12 during the descent process;

[0061] S2: In order to avoid the problem of the net fishing gear being offset during cutting and the problem of the unwinding roller body 98 rotating excessively when the subsequent net fishing gear is pulled, after the net fishing gear is pulled to a suitable position, the positioning frame 84 is driven to rotate by holding the pull handle 83 until the block 81 on the side of the positioning frame 84 is inserted into the slot 85 in the workbench 1. Before the block 81 is inserted into the slot 85, the adjustment block 862 in the adjustment slot 863 is slid. The adjustment block 862 drives the fixing rod 861 to compress the spring 864 and embed it into the workbench 1. When the block 81 is completely inserted into the slot 85, the spring 864 rebounds, thereby driving the fixing rod 861 to insert into the fixing hole 82, so as to fix the positioning frame 84 and position and fix the net fishing gear at the same time.

[0062] S3: Place one end of the net fishing gear into the interior of the fixing frame 34, turn on the second hydraulic cylinder 391, the second hydraulic cylinder 391 drives the fixing plate 394 to descend so as to fix the net fishing gear, and at the same time, the descent of the fixing plate 394 drives the second limiting block 393 to slide inside the second limiting groove 392, thereby improving the stability of the sliding process of the fixing plate 394, and then turn on the second motor 31, the second motor 31 drives the threaded rod 32 to rotate through the output end, the rotation of the threaded rod 32 drives the second nut block 33 to slide, the sliding of the second nut block 33 drives the fixing frame 34 to slide, and when the fixing frame 34 slides, it drives the guide block 310 on the surface of the guide rod 311 When the fixed frame 34 slides, the stability of the sliding process of the fixed frame 34 is improved, thereby driving the net fishing gear to be pulled. When the fixed frame 34 slides, it will drive the ear plate 35 to slide. When the ear plate 35 slides, it will drive the laser displacement transmitter 36 to move, thereby changing the distance between the laser displacement transmitter 36 and the laser displacement receiver 38. After the pulling length of the net fishing gear is set by the controller 37, when the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 reaches the length set by the controller 37, the controller 37 receives a signal at this time and can control the motor 2 31 to be turned off, thereby realizing automatic adjustment of the pulling length of the net fishing gear.

[0063] The laser displacement transmitter 36 in the present invention is an existing disclosed technology, and the selected model is LDM42.

[0064] The controller 37 in the present invention is an existing disclosed technology, and the selected model is Siemens S7-300.

[0065] The laser displacement receiver 38 in the present invention is an existing disclosed technology, and the selected model is LDM42.

[0066] The working principle and use process of the present invention are as follows: when the present invention is in use, after the mesh fishing gear on the surface of the unwinding roller body 98 is cut, the motor 93 is turned on, and the motor 93 drives the bidirectional screw rod 91 to rotate through the output end, and the bidirectional screw rod 91 rotates to drive the two groups of nut blocks 92 to move away from each other. When the nut block 92 slides, it drives the limit block 95 to slide inside the limit groove 94, thereby improving the stability of the sliding process of the nut block 92. The nut blocks 92 move away from each other, thereby driving the two groups of mounting plates 96 to move away from each other, and the unwinding roller can be moved. After the unwinding roller body 98 is disassembled and replaced with a new one, the motor 93 is turned on to drive the bidirectional screw rod 91 to rotate in the opposite direction, thereby driving the two sets of nut blocks 92 to approach each other. The two sets of nut blocks 92 approach each other and drive the two sets of mounting plates 96 to approach each other, thereby fixing the unwinding roller body 98. When the mounting plates 96 approach each other, the hexagonal block 99 at the other end of the rotating shaft 97 is driven to insert into the hexagonal groove 910 on the side of the unwinding roller body 98, thereby ensuring that the unwinding roller body 98 can rotate normally after being fixed. By opening the hydraulic cylinder 4 at the upper end of the gantry 7, the hydraulic cylinder 4 drives the pressure plate 5 to descend, and the descent of the pressure plate 5 drives the cutting knife 12 to descend, so as to cut the net fishing gear. At the same time, when the pressure plate 5 descends, it drives the slider 10 to slide inside the slide groove 6, so as to improve the stability of the descent process of the pressure plate 5 and the cutting knife 12. In order to avoid the problem of deviation of the net fishing gear during cutting, and the problem of excessive rotation of the unwinding roller body 98 when the subsequent net fishing gear is pulled, after the net fishing gear is pulled to a suitable position, the fixed position is driven by holding the pull handle 83. The positioning frame 84 rotates until the block 81 on the side of the positioning frame 84 is inserted into the slot 85 in the workbench 1. Before the block 81 is inserted into the slot 85, the adjusting block 862 in the adjusting slot 863 is slid. The adjusting block 862 drives the fixing rod 861 to compress the spring 864 and embed into the workbench 1. When the block 81 is completely inserted into the slot 85, the spring 864 rebounds, thereby driving the fixing rod 861 to insert into the fixing hole 82, so as to fix the positioning frame 84 and simultaneously realize the positioning and fixing of the net fishing gear.Put one end of the net fishing gear into the interior of the fixing frame 34, turn on the second hydraulic cylinder 391, the second hydraulic cylinder 391 drives the fixing plate 394 to descend so as to fix the net fishing gear, and at the same time, the descent of the fixing plate 394 drives the second limiting block 393 to slide inside the second limiting groove 392, thereby improving the stability of the sliding process of the fixing plate 394, and then turn on the second motor 31, the second motor 31 drives the threaded rod 32 to rotate through the output end, the rotation of the threaded rod 32 drives the second nut block 33 to slide, the sliding of the second nut block 33 drives the fixing frame 34 to slide, and when the fixing frame 34 slides, it drives the guide block 310 to slide on the surface of the guide rod 311 , thereby improving the stability of the sliding process of the fixing frame 34, thereby driving the net fishing gear to be pulled, the sliding of the fixing frame 34 will drive the lug 35 to slide, and the sliding of the lug 35 will drive the laser displacement transmitter 36 to move, so that the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 changes, and after the pulling length of the net fishing gear is set by the controller 37, when the distance between the laser displacement transmitter 36 and the laser displacement receiver 38 reaches the length set by the controller 37, the controller 37 receives a signal and controls the motor 2 31 to be turned off, thereby realizing automatic adjustment of the pulling length of the net fishing gear. ;
