DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0030] Example 1: An automatic cutting device for the edge of a welded iron mesh, referring to Figures 1-9 , including a workbench 1, a main frame 2, a cutting machine 3, a connecting frame 4, a translation frame 5, a translation seat 6, a compression spring 7, an electric turntable 8, a fixing mechanism, a telescopic member 9, a supporting plate 10 and a guide mechanism. The main frame 2 is welded to the rear side of the top of the workbench 1, and the cutting machine 3 is installed on the top of the main frame 2. The cutting machine 3 includes an automatically lifting lifting block 31 and a cutting knife 32 connected to the lower part of the lifting block 31. The cutting machine 3 is a prior art; the front side of the main frame 2 is fixedly connected to an opening connecting frame 4, and a discharge hopper is fixedly connected to the opening of the connecting frame 4. A translation frame 5 driven by a linear drive mechanism is provided on the top of the workbench 1. The linear drive mechanism is a prior art. In this embodiment, the linear drive mechanism is specifically an electric slide rail, which controls the electric slide rail to make the translation frame 5 translate in the X-axis direction. The moving frame 5 is provided with a translation seat 6 that slides on the Y-axis, and a compression spring 7 is fixedly connected between the translation seat 6 and the translation frame 5. An electric turntable 8 is installed on the top of the translation seat 6. The electric turntable 8 is a prior art. Specifically, the electric turntable 8 is rotated by a reduction motor. A fixing mechanism for fixing the iron mesh 30 is installed on the top of the electric turntable 8. Four telescopic parts 9 distributed in a cross are connected to the side of the electric turntable 8. The telescopic parts 9 are extended or shortened to adapt to the length and width of the iron mesh 30. A supporting plate 10 is provided on the end of the telescopic parts 9 away from the electric turntable 8, and a guide mechanism is provided on the translation frame 5; when the supporting plate 10 rotates around the electric turntable 8, the guiding mechanism causes the translation seat 6 to slide relative to the translation frame 5, so that the supporting plate 10 on the rear side is flush with the front side of the connecting frame 4.

[0031] refer to Figure 4-Figure 7The fixing mechanism includes a slider 82, a limiting column 83 and an arc spring 84. A circular groove 81 is opened on the top of the electric turntable 8. Four pairs of sliders 82 are arranged in the circular groove 81. An arc spring 84 is fixedly connected between each pair of sliders 82, and the top of the slider 82 is fixedly connected to the limiting column 83.

[0032] refer to Figure 5 、 Figure 6 and Figure 8 The telescopic member 9 includes a threaded sleeve 91, a slide rod 92, a connecting block 93 and a screw 94. There are four threaded sleeves 91, which are distributed in a cross shape in the XY plane and are fixedly connected to the side of the electric turntable 8. A pair of slide rods 92 are axially sliding on the threaded sleeve 91, and each pair of slide rods 92 is fixedly connected to a connecting block 93 at one end away from the electric turntable 8. The four supporting plates 10 are respectively fixedly connected to the four connecting blocks 93, and the connecting blocks 93 are rotatably connected to screws 94. The four screws 94 are respectively threadedly connected to the four threaded sleeves 91.

[0033] refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 9 The guide mechanism includes a connecting rod 111, an arc-shaped guide rod 112 and a guide column 113. Connecting rods 111 are welded on the left and rear sides of the translation frame 5. The two connecting rods 111 are perpendicular to each other. An arc-shaped guide rod 112 is fixedly connected between the two connecting rods 111. The rear end of the arc-shaped guide rod 112 is provided with a straight portion. The bottom of the connecting block 93 is connected to a guide column 113. When the guide column 113 rotates around the electric turntable 8, the guide column 113 will contact the outer side of the arc-shaped guide rod 112. When the guide column 113 moves to the straight portion, the corresponding support plate 10 is flush with the front side of the connecting frame 4, thereby automatically adjusting the position of the iron mesh 30.

[0034] refer to Figure 5 、 Figure 7 and Figure 9 The automatic cutting device for the edge of the welded iron mesh also includes a roller 61 . Two rows of rollers 61 are rotatably connected inside the translation frame 5 , and the translation seat 6 is in contact with the rollers 61 .

[0035] A horizontal iron mesh 30 has been placed on the four supporting plates 10, and the four pairs of limiting columns 83 are all located in the grid of the iron mesh 30. The arc spring 84 is in a compressed state. Under the action of the arc spring 84, the limiting columns 83 are all in contact with the iron mesh 30, thereby fixing the position of the iron mesh 30 through the four pairs of limiting columns 83, and cooperating with the supporting plates 10 to keep the iron mesh 30 stable.

[0036] The cutting machine 3 is controlled to make the lifting block 31 reciprocate up and down, driving the cutting knife 32 to lift and reciprocate, and at the same time controlling the electric slide rail to drive the translation frame 5 to move in the X-axis, driving the translation seat 6, the electric turntable 8, the limit column 83, the iron mesh 30, the telescopic part 9, the supporting plate 10, the connecting rod 111, the arc-shaped guide rod 112 and the guide column 113 to move as a whole in the X-axis, so that one side edge of the iron mesh 30 can be cut, and the waste generated by cutting falls into the discharge hopper through the opening of the connecting frame 4 for waste collection.

[0037] Then control the electric slide rail to make the translation frame 5, the iron mesh 30 and the supporting plate 10 translate to the right on the X axis, and the supporting plate 10 is separated from the connecting frame 4. Then control the reduction motor to drive the electric turntable 8 to rotate 90 degrees clockwise, driving the limit column 83, the iron mesh 30, the telescopic member 9, the supporting plate 10 and the guide column 113 to rotate 90 degrees clockwise with the electric turntable 8 as the center. During this rotation process, the guide column 113 on the left will move along the outer side of the arc guide rod 112. The shape of the arc guide rod 112 is shown in FIG. Figure 9 , thereby making the guide column 113 move backward in the Y-axis direction relative to the translation frame 5, driving the telescopic part 9, the electric turntable 8, the translation seat 6, the limit column 83, the iron mesh 30 and the supporting plate 10 to move backward in the Y-axis direction, and the roller 61 can rotate to reduce the friction force exerted on the translation seat 6 when it moves, and the compression spring 7 is compressed. When the guide column 113 moves to the straight part position of the arc-shaped guide rod 112, the supporting plate 10 moves in the Y-axis direction to a position where its rear side is flush with the front side of the connecting frame 4; at this time, the electric slide rail is controlled to make the translation frame 5, the iron mesh 30 and the supporting plate 10 translate to the left in the X-axis, and the cutting machine 3 is controlled to cut the next side of the iron mesh 30.

[0038] When it is necessary to cut the edges of the iron mesh 30 of different specifications, the screw 94 is manually rotated using a tool. Under the action of the threaded connection, the screw 94 will move in the axial direction of the threaded sleeve 91, driving the slide rod 92, the connecting block 93 and the support plate 10 to move together. By adjusting the length of the telescopic part 9, the position of the support plate 10 can be adjusted, so that the position of the support plate 10 can adapt to the length and width of the iron mesh 30.

[0039] refer to Figure 4, the lengths of the two telescopic parts 9 on the left and right sides are the minimum, the distance between the two supporting plates 10 on the left and right sides is the minimum, the lengths of the two telescopic parts 9 on the upper and lower sides are the maximum, and the distance between the two supporting plates 10 on the upper and lower sides is the maximum; when cutting the iron mesh sheets 30 of different lengths and widths, the electric turntable 8 is used to rotate the iron mesh sheets 30 90 degrees clockwise in turn, and the side of the iron mesh sheets 30 to be cut is replaced. With the cooperation of the guide column 113 and the arc-shaped guide rod 112, the rear side of the supporting plate 10 can be flush with the front side of the connecting frame 4 on the Y axis, thereby eliminating the need to manually adjust the position of the iron mesh sheet 30, effectively reducing the number of adjustments to the position of the iron mesh sheet 30, making cutting more automated, and increasing processing efficiency.

[0040] Example 2: Based on Example 1, refer to Figure 3-Figure 5 The automatic cutting device for the edge of the welded iron mesh also includes an auxiliary support plate 101, and the outer side of the threaded sleeve 91 is slidably connected to the auxiliary support plate 101; when the iron mesh 30 is placed on the four support plates 10, the auxiliary support plate 101 plays an auxiliary supporting role on the iron mesh 30, thereby avoiding the middle of the iron mesh 30 from being concave and improving the cutting effect of the edge of the iron mesh 30.

[0041] Example 3: Based on Example 2, refer to Figure 1 、 Figure 2 、 Figure 10 and Figure 11 The automatic cutting device for the edge of the welded iron mesh also includes a limiting mechanism, which includes a connecting frame 121, a limiting plate 122 and a return spring 123. The connecting frame 4 is fixedly connected to the left and right sides with a connecting frame 121. A limiting plate 122 that slides up and down is provided between the two connecting frames 121, and a return spring 123 is fixedly connected between the limiting plate 122 and the connecting frame 121.

[0042] refer to Figure 1 、 Figure 2 、 Figure 10 and Figure 11 A recessed portion 1221 is provided in the middle of the limiting plate 122, and the recessed portion 1221 prevents the cutting knife 32 from contacting the limiting plate 122 when it moves downward. Chamfered portions 1222 are provided on the side of the connecting frame 121 away from the connecting frame 4 and on the left and right sides of the limiting plate 122.

[0043] Initially, the edge of the iron mesh 30 is located between the limiting plate 122 and the connecting frame 4. The limiting plate 122 limits the edge of the iron mesh 30 to prevent the edge of the iron mesh 30 from curling up; since the connecting frame 121 and the limiting plate 122 are both provided with chamfered portions 1222, the edge of the iron mesh 30 can smoothly enter between the limiting plate 122 and the connecting frame 4, thereby facilitating the cutting of the iron mesh 30 and improving the cutting effect.

[0044] refer to Figure 2The automatic cutting device for the edge of the welded iron mesh also includes a pressing block 13. The front side of the lifting block 31 is fixedly connected to the pressing block 13. The pressing block 13 is made of rubber. When the pressing block 13 moves downward, it will contact the recessed portion 1221 of the limiting plate 122.

[0045] When the lifting block 31 and the cutting knife 32 descend, the lifting block 31 drives the pressing block 13 to descend. After the pressing block 13 contacts the limiting plate 122, the lifting block 31 and the cutting knife 32 continue to descend to perform the cutting work. The pressing block 13 made of rubber material can be deformed. The pressing block 13 presses the limiting plate 122, so that the limiting plate 122 presses the edge of the iron mesh 30 to prevent the iron mesh 30 from shifting during cutting, thereby further improving the cutting effect.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
