AI Technical Summary
Existing aquaculture netting edge trimming devices suffer from problems such as complex structure, high equipment cost, inconvenient maintenance, and incomplete cutting of weft wire ends. In particular, the weft wire ends at the "V"-shaped apex are not completely cut off, requiring secondary manual trimming, which is labor-intensive.
A bevel trimming device for aquaculture partition nets was designed, comprising a transverse slide rail, a sliding seat, a cutting frame, a servo motor, and upper and lower cutting blades. The servo motor controls the movement of the cutting frame. The upper cutting blade has a trapezoidal blade body, with the front end of the longitudinal wire baffle inclined. The cutting blade cuts the weft wire end against the outer side of the warp wire to avoid hooking. The lower cutting blade works in conjunction to remove the top corner weft wire. The structure is simple and the equipment cost is low.
It achieves complete removal of the weft wire ends, eliminating the need for secondary manual trimming, reducing labor intensity, minimizing equipment space requirements, facilitating maintenance, and improving labor efficiency and cutting results.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of mesh trimming device, especially relates to a breeding screen mesh bevel trimming device. BACKGROUND
[0002] In the breeding industry, breeding screen mesh is widely used. The existing breeding screen mesh includes weft and warp, and the warp on the outermost side of the screen mesh is in the shape of V. In the welding process of the screen mesh, the end of the weft on the outer side of the outermost warp needs to be cut off. At present, the end of the weft is mainly trimmed in the following two ways:
[0003] Firstly, the end of the weft on the side of the outermost warp which is a straight wire is trimmed by a trimming device, and the end of the weft on the side of the outermost warp which is in the shape of V is trimmed manually. This method has high labor intensity and low labor efficiency;
[0004] Secondly, the end of the weft on the side of the outermost warp which is in the shape of V is also trimmed by a trimming device. At present, the trimming device includes horizontal sliding rails with fixed bases at both ends, a sliding seat arranged on the horizontal sliding rails, a cutting frame arranged on the sliding seat, an upper cutting knife connected with a cutting cylinder arranged above the cutting frame, a lower cutting knife arranged on the cutting frame corresponding to the upper cutting knife below the upper cutting knife, a servo motor arranged on one of the fixed bases, a screw rod arranged on the power rod of the servo motor, a screw nut matched with the screw rod arranged on the sliding seat, the upper cutting knife including a fixed handle arranged above and a blade body arranged below the fixed handle, the blade body including a blade head arranged above, longitudinal wire baffles arranged below the blade head and a horizontal wire passage arranged between the two longitudinal wire baffles, a cutting edge arranged above the horizontal wire passage, and the blade body being a plane. In order to cut the weft on the outer side of the oblique warp, the top rod of the cutting cylinder is provided with an upper cutting frame, the upper cutting frame is provided with an upper cutting knife shaft connected with a steering cylinder, the upper cutting knife is fixed with the upper cutting knife shaft, and when the end of the weft on the outer side of the oblique warp is cut, the angle of the upper cutting knife is adjusted by the steering cylinder, so that the plane where the front surface of the upper cutting knife is located is parallel to the axis of the warp. In this way, when the end of the weft on the outer side of the oblique warp is cut, the warp is not damaged, and the end of the weft is cut off completely. However, the breeding screen mesh bevel trimming device has the following defects: firstly, when the end of the weft on the outer side of the oblique warp is cut, the damage of the longitudinal wire baffles to the oblique warp can be effectively avoided, but for the weft on the top corner of the V-shaped part, the warp on both sides of the top corner will block the longitudinal wire baffles, so that the end of the weft is not cut off completely, and the weft needs to be trimmed manually again, which is time-consuming and laborious, and the outer surfaces of the warps on both sides are also damaged; secondly, the structure is complex, the cost of equipment is increased, the maintenance space is small, and the maintenance and repair are not convenient.

[0022] The fixed base 11 is fixed on the welded frame at both ends of the screen, when trimming the weft yarn outside the warp yarn in one direction, the servo motor 8 controls the cutting frame 4 to move along the horizontal slide rail 12, so that the upper cutter 6 moves above the weft yarn end to be cut, the front surface of one of the longitudinal silk baffles 622 in the upper cutter 6 is attached to the outside of the oblique warp yarn, and the longitudinal silk baffle 622 on the other side is away from the outside of the longitudinal silk, the cutting edge 63 can cut off the weft yarn end by attaching to the outside of the warp yarn, and the residual part of the end bends downward along the outside of the warp yarn when the end is cut off, so that a hook is not formed on the outside of the warp yarn. When cutting the weft yarn at the top angle of the "V" shaped warp yarn, the front end faces of the longitudinal silk baffles on both sides of the cutting edge 63 are respectively aligned with the outside faces of the warp yarn on both sides, and when the upper cutter 6 is cut, the front surfaces of the two longitudinal silk baffles 622 are respectively attached to the outside of the corresponding oblique warp yarn, so that the cutting edge can cut off the weft yarn end by attaching to the outside of the warp yarn, and the residual part of the end bends downward along the outside of the warp yarn when the end is cut off, so that a hook is not formed on the outside of the warp yarn.
