Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-3, the net breaking mechanism of the automatic net winding device comprises a fixing frame 1, a net pressing block 2 fixed on the fixing frame 1, a cutter pair knife 3, a travel rod 4 in sliding connection with the fixing frame 1, and a net pressing plate 5 fixedly connected with the travel rod 4.

The fixing frame 1 plays a role in supporting the whole screen breaking mechanism. The stroke rod 4 is slidably provided on the fixed frame 1 and can move linearly. The driving component 6 is fixed on the fixed frame 1 and used as a power source for driving the travel rod 4 to slide relative to the fixed frame 1, and the travel rod 4 is fixedly connected with the screen pressing plate 5, so that the screen pressing plate 5 can make repeated linear motion along with the travel rod 4 and can be attached to or away from the screen pressing block 2. When the screen pressing plate 5 and the screen pressing block 2 are attached together, one end of the wound object is convenient to be clamped between the screen pressing plate and the screen pressing block,

the cutter pair knife 3 is detachably connected to the fixed frame 1, preferably by using screws, and is a plate-shaped object; the net cutting tool rest 7 is fixed on the net pressing plate 5, the tool rest pressing plate 8 is detachably connected to the net cutting tool rest 7, and a horizontally placed blade is clamped between the net cutting tool rest 7 and the tool rest pressing plate 8. When the screen pressing plate 5 is attached to the screen pressing block 2, the blade moves to the upper portion of the top surface of the cutter pair knife 3 to break the screen. The smaller the gap between the blade and the top surface of the cutter sub-blade 3, the better the cutting effect. The blade is fixed in a clamping mode through the net cutting blade holder 7 and the blade holder pressing plate 8, and the blade holder pressing plate 8 is only required to be removed, so that the blade can be replaced conveniently. With the increase of the number of winding turns, the end of the wound object does not affect the winding work even if it is released. At the end of the winding work, the net pressing plate 5 is far away from the net pressing block 2, and meanwhile, the stroke rod stretches, so that the last circle of the wound object surrounds the stroke rod 4. The wound object is then brought onto the travel bar 4, and is pressed between the blade and the cutter set 3 as the travel bar 4 approaches the screen block 2.

Preferably, as shown in fig. 4, the cutter holder pressing plate 8 is overlapped on the cutter holder 7, the outer contours of the cutter holder pressing plate and the cutter holder pressing plate are consistent, and two screws can penetrate through the cutter holder pressing plate and the cutter holder pressing plate to be detachably fixed into a whole.

The net cutting knife rest 7 and the knife rest pressing plate 8 are provided with openings facing the cutter auxiliary knife 3, and the whole machine is similar to a U shape. The up-down through notch is used for exposing the middle part of the blade, and two ends of the blade are clamped by the net cutting blade seat 7 and the blade seat pressing plate 8. The tool apron pressing plate 8 is disassembled according to the scheme, the tool apron pressing plate is not required to be completely disassembled, and the screw is slightly screwed. The blade does not need to be additionally perforated and is clamped between the two. When the cutter pair 3 needs to be ground, an adjusting gasket can be added between the cutter net cutter seat 7 and the cutter seat pressing plate 8 to adjust the position of the cutter blade.

Preferably, the stroke rods 4 are arranged at the upper end and the lower end of the screen pressing plate 5;

the driving assembly 6 comprises a driving mechanism and a sliding rod 61, one end of the sliding rod 61 is fixed at the middle position of the screen pressing plate 5, and the other end of the sliding rod 61 drives the screen pressing plate 5 to linearly move under the action of the driving mechanism. One end of the slide bar 61 moves to drive the screen pressing plate 5 to move.

In particular, the slide bar 61 is interposed between the two travel bars 4. One side surface of the fixing frame 1 is sequentially fixed with a travel rod 4, a cutter pair knife 4, a slide rod 61, a net pressing block and another travel rod 4 from top to bottom.

Specifically, the driving mechanism is an oil cylinder, and the output end of the piston of the oil cylinder is fixedly connected with the slide rod 61.

Fig. 2 and 3 are respectively two states of cylinder feeding and cylinder withdrawing, two stroke rods are arranged, one end of each stroke rod is connected by a net pressing plate, and the other end of each stroke rod penetrates through the toothed ring frame when in use, so that the net cutting motion is guided; the cutter holder is fixed on the net pressing plate and moves along with the slide rod; the cutter pair knife is fixed on the large gear bracket, wherein the upper edge surface of the cutter pair knife is away from the lower surface of the blade, and the cutter pair knife is as small as possible under the condition of no interference, thereby playing a role in cutting the net. The application method of the net breaking mechanism applied to the net winding mechanism can refer to application number 202221337698.2 and Chinese patent of the utility model named as an automatic net winding mechanism, and the description is omitted here.

In order to achieve the purpose that the fixed frame 1 stably supports the travel rod 4 and the oil cylinder, the fixed frame 1 comprises a first fixed plate 11 and a second fixed plate 12 which are arranged in parallel and fixedly, and the travel rod 4 respectively penetrates through the first fixed plate 11 and the second fixed plate 12; so that the holder 1 has two support points for the travel bar 4. The cutter pair 3 and the driving mechanism are respectively fixed at both sides of the first fixing plate 11.

While certain exemplary embodiments of the present utility model have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the utility model, which is defined by the appended claims.
