Description

Technical Field

[0001] This utility model belongs to the technical field of metal wire mesh weaving machines, specifically relating to a weft insertion degree detection mechanism and a metal wire mesh weaving machine. Background Technology

[0002] Metal wire mesh weaving machines are mainly used for weaving metal wire mesh. Several warp wires arranged in parallel form a weaving opening after passing through an alternating mechanism. The weft wires transmitted from the weft wire supply mechanism are then inserted into the weaving opening through the arrow-feeding mechanism (the arrow drives the weft wires). Subsequently, the beat-up mechanism pushes the inserted weft wires forward.

[0003] In existing technologies, during the process of the weft-beating mechanism pushing the entire weft wire forward, it is necessary to ensure the smooth transfer of the mesh surface and the coordinated operation of the weft-beating mechanism to ensure uniform mesh size after the weft wire is pushed into place. However, if the weft-beating mechanism or the wire mesh weaving machine malfunctions at any moment, it may result in the weft wire not reaching its proper position after being pushed, leading to larger mesh size; or the weft wire may be tilted, resulting in uneven mesh size distribution, meaning the weft-beating degree cannot be effectively guaranteed. If these problems are not addressed promptly, they will affect the production quality of the wire mesh. Utility Model Content

[0004] This utility model provides a weft insertion degree detection mechanism and a metal wire mesh weaving machine, which aims to solve the problem of poor practicality caused by the inability of existing weft insertion mechanisms to guarantee the degree of weft insertion.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A weft insertion testing mechanism is provided, comprising:

[0007] A gantry frame is fixed on the frame of a metal wire mesh weaving machine. The gantry frame has an erection section that is arranged along the length of the weft wire and located above the weft-beating mechanism.

[0008] Two vision cameras are provided, with each vision camera arranged at one end of the erected part.

[0009] Two installation adjustment components are provided, each located at one end of the erection part and for mounting the two vision cameras respectively; each installation adjustment component is used to adjust the corresponding vision camera so that the lens end of each vision camera is facing the two ends of the weft wire respectively.

[0010] In one possible implementation, each of the installation adjustment components includes:

[0011] A worm gear reducer has an input end and an output end;

[0012] The mounting base has a connection hole for coaxial connection of the input end, and the mounting base is for mounting the vision camera;

[0013] The worm gear reducer is used to transmit power from the input end to the output end to drive the mounting base to pitch and rotate.

[0014] In one possible implementation, the mounting base includes:

[0015] A vertical plate, vertically arranged; the connecting holes are arranged on the vertical plate;

[0016] A horizontal plate is provided, with one end of the horizontal plate integrally connected to the top of the vertical plate. The horizontal plate is used for mounting the vision camera.

[0017] In one possible implementation, each of the mounting and adjusting components further includes a servo motor, which is fixed to the worm gear reducer and powered to the input end.

[0018] In one possible implementation, the bottom end of the worm gear reducer has a connecting plate portion; the connecting plate portion is bolted to the mounting portion;

[0019] Both ends of the erected part are provided with long sliding openings for the bolts to pass through and which can slide in the direction of the weft yarn length.

[0020] In one possible implementation, the gantry includes:

[0021] There are two uprights, which are spaced apart along the length of the weft wire and are fixedly connected to the frame of the wire mesh weaving machine.

[0022] The crossbeam is connected to the two uprights at both ends, and the crossbeam is the erection part.

[0023] In one possible implementation, each of the vision cameras is located on the outside of the crossbeam.

[0024] A wire mesh weaving machine is also provided, comprising:

[0025] The aforementioned weft insertion testing agencies;

[0026] The matching controller is electrically connected to each of the visual cameras in the weft insertion degree detection mechanism;

[0027] When the controller receives feedback of mesh defects from the two vision cameras, it stops the machine.

[0028] The weft insertion degree detection mechanism provided in this implementation uses a gantry frame to ensure a support platform is set up on the wire mesh weaving machine, and that the erected part is positioned above the weft insertion mechanism. The two vision cameras can detect the mesh formed by the pushed weft wires at both ends, ensuring compatibility with longer weft wires or wider wire meshes, and allowing for indirect detection of longer weft wires. This detection method ensures timely detection and identification of problems such as weft wire not being pushed into place or weft wire tilting, facilitating timely machine stoppage and adjustment by operators, thereby preventing subsequent wire mesh quality issues. The included installation and adjustment components ensure the installation of the two vision cameras and allow for adjustment of the camera lenses, ensuring that the vision cameras are aligned with the weft wires and guaranteeing detection effectiveness.

[0034] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] Please refer to the following: Figure 1 and Figure 3The weft insertion degree detection mechanism provided by this utility model will now be described. The weft insertion degree detection mechanism includes a gantry frame 10, vision cameras 20, and mounting and adjusting components 30. The gantry frame 10 is fixed on the frame of a wire mesh weaving machine, and has an erection section arranged along the length of the weft yarn and located above the weft insertion mechanism. Two vision cameras 20 are provided, each positioned at one end of the erection section. Two mounting and adjusting components 30 are provided, each positioned at one end of the erection section, and each is used to mount the two vision cameras 20. Each mounting and adjusting component 30 can adjust the corresponding vision camera 20 so that the lens end of each vision camera 20 faces both ends of the weft yarn.

[0036] The weft insertion degree detection mechanism provided in this embodiment operates on the principle that two vision cameras 20 are respectively arranged at both ends of the weft yarn, enabling them to detect the weft yarn pushed by the weft insertion mechanism. After the weft yarn is pushed to its limit position by the weft insertion mechanism, the mesh formed between the pushed weft yarn and the previous weft yarn is detected. When the mesh aperture detected by one vision camera 20 is larger than the mesh aperture detected by the other vision camera 20, it indicates that the weft yarn is tilted. When the mesh aperture detected by both vision cameras 20 is larger than a set value, it indicates that the weft yarn has not been pushed to the correct position.

[0037] Compared with existing technologies, the weft insertion degree detection mechanism provided in this embodiment features a gantry frame 10 that ensures a support platform is set up on the wire mesh weaving machine and that the erected part is located above the weft insertion mechanism. The two vision cameras 20 can detect the mesh formed by the pushed weft wires at both ends, ensuring adaptability to longer weft wires or wider wire meshes, and allowing for indirect detection of longer weft wires. This detection method ensures timely detection and identification of problems such as weft wire not being pushed into place or weft wire tilting, facilitating timely machine stoppage and adjustment by operators, thereby preventing subsequent wire mesh quality issues. The installation and adjustment assembly 30 ensures the installation of the two vision cameras 20 and also allows for adjustment of the lens ends of the vision cameras 20, ensuring that the vision cameras 20 are aligned with the weft wire and guaranteeing detection effectiveness.

[0038] In some embodiments, the installation adjustment component 30 described above may be adopted as follows: Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 Each mounting and adjusting assembly 30 includes a worm gear reducer 31 and a mounting base 32. The worm gear reducer 31 has an input end and an output end. The mounting base 32 has a connection hole for coaxial connection of the input end, and the mounting base 32 is for mounting the vision camera 20.

[0039] Among them, the worm gear reducer 31 can transmit power from the input end to the output end to drive the mounting base 32 to pitch and rotate.

[0040] In the worm gear reducer 31, the input end corresponds to the worm, and the output end corresponds to the worm wheel. The output end is connected to the mounting base 32. The mounting base 32 can be tilted by adjusting the rotation of the input end, thus ensuring that the lens of the vision camera 20 is set vertically or tilted downwards. This effectively ensures that it corresponds to both ends of the weft wire, adapting to different widths of metal wire mesh. The ability of the vision camera 20 to tilt ensures that it is tilted. When the vision camera 20 is tilted downwards for shooting, the shooting range is increased, further adapting to longer weft wires and thus ensuring the detection effect.

[0041] Moreover, the worm gear driving the worm wheel ensures that it can form a self-locking mechanism, thereby ensuring that the position of the vision camera 20 is fixed after it is flipped.

[0042] It should be noted that the worm gear reducer 31 may include a housing, a shaft rotatably mounted on the housing, a worm wheel coaxially connected to the shaft, and a worm gear perpendicular to the shaft and meshing with the worm wheel. One end of the shaft extends out of the housing to form an output end. One end of the worm gear extends out of the housing to form an input end. This technology is prior art and will not be described in detail here.

[0043] In some embodiments, the mounting base 32 may be as follows: Figure 2 The structure shown. See also Figure 2 The mounting base 32 includes a vertical plate 321 and a horizontal plate 322. The vertical plate 321 is vertically oriented. Connecting holes are provided on the vertical plate 321. The horizontal plate 322 is horizontally oriented, and one end of the horizontal plate 322 is integrally connected to the top of the vertical plate 321. The horizontal plate 322 is used for mounting the vision camera 20.

[0044] The vertical plate 321 ensures connection to the output end and also guarantees the fixed connection of the horizontal plate 322. The horizontal plate 322 ensures a detachable connection to the vision camera 20, which can be achieved using a bolt 14 fixing structure. The integrated connection between the vertical plate 321 and the horizontal plate 322 ensures synchronous rotation of the two plates, thereby facilitating angle adjustment of the lens end of the vision camera 20.

[0045] In some embodiments, see Figure 2 Each mounting and adjustment component 30 also includes a servo motor, which is fixed on the worm gear reducer 31 and connected to the input power.

[0046] The servo motor setting ensures electric adjustment and is easy to control. The servo motor is existing technology and will not be described in detail here.

[0047] In some embodiments, the worm gear reducer 31 described above can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The worm gear reducer 31 has a connecting plate 311 at its bottom end. The connecting plate 311 is connected to the mounting bolt 14.

[0048] Both ends of the erection section are provided with long sliding openings 13 through which bolts 14 can pass and which can slide in the direction of the weft thread length.

[0049] Since the width of the metal mesh woven by the metal mesh weaving machine varies, the worm gear reducer 31 is designed as a sliding structure to adapt to the weaving of different widths of wire mesh, ensuring that the vision camera 20 can always be positioned at both ends of the weft wire, thereby ensuring the detection effect.

[0050] It should be noted that, regarding the two ends mentioned in this embodiment, the weft yarn can be divided into four equal parts, and the two vision cameras 20 can be respectively located in the quarter-length segment at both ends of the weft yarn.

[0051] In some embodiments, the gantry 10 described above can be adopted as follows: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The gantry frame 10 includes uprights 11 and crossbeams 12. There are two uprights 11, spaced apart along the length of the weft threads, and both are fixedly connected to the frame of the wire mesh weaving machine. The crossbeams 12 are connected to the two uprights 11 at both ends, serving as the erection section.

[0052] The two uprights 11 ensure that the crossbeam 12 is supported, thus ensuring that the crossbeam 12 is located above the weft insertion mechanism, which facilitates the installation of the vision camera 20 and does not affect the operator's operation of the wire mesh weaving machine. The structure is simple, easy to manufacture, and has stable load-bearing capacity.

[0053] In some embodiments, the positional relationship between the aforementioned visual camera 20 and the crossbeam 12 can be as follows: Figure 2 The structure shown. See also Figure 2 Along the direction of warp transmission, each vision camera 20 is located outside the crossbeam 12. The location of the vision camera 20 outside the crossbeam 12 can prevent the vision camera 20 from being blocked by the crossbeam 12 during the detection process, thereby ensuring the detection effect.

[0054] This application also provides a wire mesh weaving machine, including the aforementioned weft insertion degree detection mechanism and a matching controller. The controller is electrically connected to each of the vision cameras 20 in the weft insertion degree detection mechanism.

[0055] When the controller receives feedback from the two vision cameras 20 regarding mesh defects, it stops the machine.

[0056] Compared with existing technologies, the weft insertion degree detection mechanism and wire mesh weaving machine provided in this embodiment are equipped with a weft insertion degree detection mechanism. The two vision cameras 20 in this mechanism can detect the mesh formed by the pushed weft at both ends of the weft wire, ensuring adaptability to longer weft wires or wider wire meshes, and guaranteeing indirect detection of longer weft wires. This detection method ensures timely detection and identification of problems such as weft wire not being pushed into place or weft wire tilting, facilitating timely machine stoppage and adjustment by operators, thereby avoiding subsequent wire mesh quality problems. The controller analyzes the mesh after receiving the detection signal. When the mesh in the two vision cameras 20 is inconsistent, or the mesh is larger than the mesh formed by the previous weft wire, the controller stops the machine, allowing operators to make timely adjustments and effectively ensuring the product quality of the wire mesh.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
