Description

Technical Field

[0001] The utility model relates to the technical field of fishing net production, in particular to a marine fishing net automatic winding device. Background Art

[0002] Most of the fishing nets currently in use are made of synthetic fibers.

[0003] There are various styles of fishing nets. In the process of producing fishing nets, first, the fishing net lines need to be woven into a long strip-shaped fishing net, and then the fishing net is wound around a winding roller. Finally, the fishing net is cut and sewn according to the required style. During the process of winding the fishing net, the operator needs to manually wind one end of the fishing net around the winding roller, and then the automatic winding can be carried out, which is inconvenient to operate. At the same time, during the use of the fishing net, due to the different depths of the sea area, the required sizes of the fishing nets are also different. During the winding process of fishing nets of different specifications, the winding sizes are different. If the same aperture winding roller is used, when winding a large-sized fishing net, the large-aperture winding roller causes the overall volume of the fishing net roll to be relatively large, occupying a large volume; when winding a small-sized fishing net, the small-aperture winding roller results in fewer winding layers of the fishing net and poor overall rigidity, making it impossible to store the fishing net upright. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of this, the embodiments of this specification provide a marine fishing net automatic winding device with an adjustable aperture size of the winding roller.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the utility model provides the following technical solutions: A marine fishing net automatic winding device includes a bottom plate and a winding roller. An fixed plate and a movable plate are provided on the bottom plate. A motor for driving the winding roller to rotate is provided on the fixed plate. The winding roller includes a rotating shaft, a telescopic rod, and a plurality of support blocks. The plurality of support blocks are arranged around the central axis of the winding roller, and the support blocks are connected to the rotating shaft through the telescopic rod.

[0008] Compared with the prior art, the advantages of the utility model are as follows: The surface of the fishing net contacts the support blocks. The motor drives the rotating shaft to rotate, realizing the automatic winding of the fishing net on the support blocks. By synchronously adjusting the length of the telescopic rod, the change of the aperture size of the winding roller is realized, meeting the requirements of winding fishing nets with different apertures.

[0009] In some embodiments, a positioning component is provided inside the support block, and a positioning groove is provided on the outer wall of the support block; the positioning component includes a positioning slider and a positioning button. Pressing the positioning button causes the positioning slider to retract from the positioning groove, releasing the limit on the fishing net. Through this improvement, when the fishing net is wound around the winding roller, the positioning slider hooks the fishing net and drives the fishing net to wind. During the process of removing the fishing net, pressing the positioning button causes the positioning slider to retract from the positioning groove, preventing the positioning slider from hooking the fishing net, simplifying the winding process and facilitating the operation of the operator.

[0010] In some embodiments, the positioning component includes a positioning base, a first return spring, and a second return spring.

When the second inclined surface abuts against the first inclined surface, the positioning slider moves downward. Through this improvement, pressing the positioning button causes the second inclined surface to move in the direction of the first inclined surface. When the second inclined surface abuts against the first inclined surface, the positioning slider moves downward; releasing the positioning button, the first return spring and the second return spring recover their deformation, realizing the reset of the positioning slider and protruding from the positioning groove.

[0011] In some embodiments, a lead screw adjustment structure is provided on the bottom plate, and the movable plate is installed on the lead screw adjustment structure. Through this improvement, through the setting of the lead screw adjustment structure, the movement of the movable plate is realized, and the winding of fishing nets of different lengths is realized, with higher cost performance.

[0012] In some embodiments, the lead screw adjustment structure includes a ball screw, a lead screw bearing, a handle, a lead screw nut, a sliding seat, and a pointing rod. Ear plates are installed at both ends of the ball screw, and both ends of the ball screw are rotatably connected to the lead screw bearings installed on the ear plates. The outer end of the ball screw is directly connected to the handle. The lead screw nut is installed on the ball screw, the sliding seat is installed on the lead screw nut, and the movable plate is fixedly installed on the sliding seat. Through this improvement, the operator can laterally move the movable plate by operating the handle, changing the distance between the movable plate and the fixed plate to adapt to the installation and disassembly requirements of winding rollers of different lengths, and at the same time facilitating the disassembly of the fishing net.

[0013] In some embodiments, the pointing rods are provided on both sides of the ball screw, and both ends of the pointing rods are respectively connected to the ear plates. The sliding seat includes through holes corresponding to the positions of the pointing rods, and the sliding seat is sleeved on the pointing rods through the through holes. Through this improvement, the setting of the pointing rods makes the operation of the sliding seat more stable.

[0014] In some embodiments, the telescopic rod is provided with fixing holes, and the fixing rod is inserted into the fixing holes to fix the telescopic rod. Through the above improvement, the telescopic rod is fixed by inserting the fixing rod into the fixing holes, preventing the length of the telescopic rod from changing during the operation of the device.
