Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] like Figure 1 and 2As shown, an active protective net cable positioning, cutting, and feeding machine includes a feeding mechanism and a cutting device. The feeding mechanism includes a mounting base 101 and two feeding wheels 201. The two feeding wheels 201 are rotatably mounted on one side of the mounting base 101, with corresponding grooves, allowing the net cable to pass through the gap between the two feeding wheels 201 and contact the grooves of the two feeding wheels 201 respectively. When the feeding wheels 201 rotate, the net cable is moved by friction to feed the cable. The two feeding wheels 201 are a driving wheel and an auxiliary wheel, respectively, with the same structure. The driving wheel is driven by a motor to rotate, and the auxiliary wheel is located above the driving wheel and slides towards the driving wheel. It is used to adjust the size of the gap between the auxiliary wheel and the driving wheel, thereby pressing the net cable together. This is used to compensate for changes in the diameter of the net cable in the vertical direction, facilitating the positioning of the net cable.

[0028] The feeding wheel 201 includes two side halves that slide in opposite directions along the axial direction and an elastic element; a motor is connected to one side of the driving wheel's side half and is mounted on the mounting base 101; each side half consists of a wheel platform and a sleeve; the sleeve is located on one side of the wheel platform, and one sleeve is fitted onto the other sleeve, allowing the two side half wheels to move along the axial direction of the sleeve; a groove is formed between the two wheel platforms, and the net cable is placed in the groove; the elastic element is preferably a first spring 2015, located inside the sleeve, with its two ends connected to the two wheel platforms respectively, used to pull the two wheel platforms inward; when the net cable is placed in the groove between the two wheel platforms, as the diameter of the net cable increases or decreases, the two wheel platforms can move away from or closer to fit the net cable; the two side half wheels are connected by a limiting structure to restrict the movement of the two side half wheels in the axial direction and prevent them from rotating relative to each other, so that the two side half wheels can rotate synchronously;

[0029] The wire cutting device includes a positioning plate 301 and a cutting blade 302; the positioning plate 301 is provided with a wire hole, and the wire mesh can pass through the wire hole via the wire feeding wheel 201; the cutting blade 302 is slidably disposed on one side of the positioning plate 301 toward the wire hole, and is used to cut the wire mesh passing through the wire hole.

[0030] like Figure 1 As shown, the top of the mounting base 101 is provided with a support plate 102, and a second hydraulic rod 303 is provided on one side of the bottom. Its movable end is connected to the shearing cutter 302, which is used to drive it to move toward the wire hole to cut the net cable. The size of the wire hole is adapted to the maximum diameter of the net cable that can be passed through the wire feeding wheel 201. It is only used to limit the shaking of the net cable during shearing. The positioning plate 301 has a certain thickness. After the shearing cutter 302 cuts the net cable, one end of it is placed in the wire hole and can then continue to move with the wire feeding wheel 201.

[0031] Furthermore, the part of the shearing blade 302 that contacts the mesh cable has an arc-shaped cutting edge, which is used to cut the mesh cable with a circular cross-section to prevent it from unraveling.

[0032] like Figure 2 As shown, the mounting base 101 is provided with a movable groove 103, in which a sliding mounting block 202 is slidably mounted; and a sliding groove 104 is provided on the side wall of the movable groove 103, and a sliding strip is also provided on the side wall of the sliding mounting block 202, which is slidably mounted in the sliding groove 104 to ensure that the sliding mounting block 202 moves along the sliding groove 104, thereby ensuring that the grooves of the auxiliary wheel and the driving wheel are aligned vertically to avoid deviation; one side of the auxiliary wheel is rotatably mounted on the sliding mounting block 202, so that the auxiliary wheel can move synchronously with the sliding mounting block 202, thereby making the auxiliary wheel move closer to or away from the driving wheel; a first hydraulic rod 203 is provided on one side of the movable groove 103, the movable end of which is connected to the sliding mounting block 202 to drive the sliding mounting block 202 to move along the movable groove 103;

[0033] Specifically, the wheel platform is platform-shaped, with its side walls inclined towards its adjacent side half of the wheel. When the net cable is placed between the two wheel platforms, the side walls of the wheel platform can be set towards the net cable, increasing the contact area with the net cable.

[0034] More specifically, an anti-slip pad 2016 is also provided at the contact point between the wheel stand side wall and the net cable to increase the friction between the wheel stand side wall and the net cable, further preventing slippage during the cable feeding process and improving its positioning accuracy.

[0035] like Figure 3 As shown, the limiting structure includes a limiting groove 2012 and a limiting strip 2014, which are respectively disposed on the sleeve sidewalls of the two side half-wheels. The limiting strip 2014 is slidably disposed in the limiting groove 2012, so that one side half-wheel slides axially along the limiting groove 2012. In conjunction with the first spring 2015 disposed inside the sleeve, it can automatically compensate for changes in the diameter of the net cable.

[0036] The wire feed roller 201 adopts an axial sliding side half-wheel plus elastic element structure, which is used to compensate for the change of the net cable diameter in the lateral direction and facilitate the positioning of the net cable.

[0037] like Figure 4 As shown, in one embodiment, an auxiliary block 204 is rotatably provided on the side of the wire feeding wheel 201 away from the mounting base 101; the auxiliary blocks 204 on the two wire feeding wheels 201 are connected by an elastic element; and a first limiting rod 206 is provided on one auxiliary block 204, and a through hole is provided on the other auxiliary block 204, so that the first limiting rod 206 passes through the through hole; and the elastic element is preferably a second spring 205, which is arranged around the first limiting rod 206 to limit the displacement of the wire feeding wheel 201 away from the mounting base 101, reduce the vibration of the wire feeding wheel 201, and extend the service life of the equipment.

[0038] like Figure 5As shown, in one embodiment, an auxiliary positioning mechanism is also included, disposed on the mounting base 101 and located on one side of the gap between the two feed wheels 201; the auxiliary positioning mechanism includes four positioning blocks 401 arranged around the gap between the feed wheels 201; adjacent positioning blocks 401 are connected by elastic elements; pulleys 404 are rotatably provided on the side surface of each of the four positioning blocks 401 facing their center, and when the net passes through the center of the four positioning blocks 401, the pulleys 404 respectively contact the side wall of the net; the four positioning blocks 401 are respectively arranged corresponding to four side half wheels; and The positioning block 401 corresponding to the side half wheel connected to the motor is the reference positioning block 401, which is fixedly connected to the mounting base 101. The pulley 404 on the reference positioning block 401 is tangent to the wheel seat side wall of the corresponding side half wheel. Since the positions of the reference positioning block 401 and its corresponding wheel seat are fixed relative to the mounting base 101, the positions of the mesh cables of different diameters that are in contact with the pulley 404 on the reference positioning block 401 and the wheel seat side wall remain unchanged. The other three positioning blocks 401 move with the compression or unfolding of the elastic element, thereby adapting to mesh cables of different diameters.

[0039] Specifically, the positioning block 401 adjacent to the reference positioning block 401 is the adjacent positioning block 401, which has a through hole. The reference positioning block 401 has a second limiting rod 403 on its side wall facing the adjacent positioning blocks 401 on both sides, which passes through the through hole, so that the adjacent positioning block 401 can move along the second limiting rod 403. The positioning block 401 opposite to the reference positioning block 401 is the relative positioning block 401, which has a through hole on its side wall facing the adjacent positioning blocks 401 on both sides, and the through holes on both sides are staggered. The adjacent positioning blocks 401 on both sides have a second limiting rod 403 facing the relative positioning block 401, which passes through the through hole, so that the relative positioning block 401 can move along the second limiting rod 403. This allows the space inside the four positioning blocks 401 to change as the positioning blocks 401 move along the second limiting rod 403, so as to adapt to the positioning of nets of different diameters.

[0040] The working principle of this embodiment is as follows:

[0041] This utility model discloses an active protective net cable positioning, cutting, and feeding machine. The net cable is sequentially passed through the space inside four positioning blocks 401, the gap between two feeding wheels 201, and the wire hole on the positioning plate 301. The pulleys 404 on the positioning blocks 401 are in contact with the side wall of the net cable, and the wheel base side wall of the feeding wheels 201 is in contact with the net cable. The net cable is positioned and transported, and the feeding wheels 201 can fit tightly with the net cable when rotating, avoiding slippage and improving the accuracy of its transport and positioning. Then, the second hydraulic rod 303 can drive the cutting blade 302 to cut the net cable.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
