[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please also read Figures 1 to 3 , the wire mesh weaving device with adjustable weft beating times provided by the present invention is now described. The wire mesh weaving device with adjustable weft beating times comprises a frame 80, a warp feeding mechanism, a variable interlacing mechanism, a sword throwing weft insertion mechanism and a winding mechanism, and is characterized in that it also comprises a weft beating mechanism. The weft beating mechanism comprises a swing rod 10, a driving structure 20, an adjusting member 30, a first connecting rod 40, a rotating rod 50, a second connecting rod 60 and a weft pushing assembly 70. One end of the swing rod 10 is rotatably arranged on the frame 80, and the other end extends out. The driving structure 20 is arranged on the frame 80, and the driving structure 20 has a mounting end. The adjusting member 30 is rotatably arranged on the swing rod 10 and is rotatably connected to the mounting end. The adjusting member 30 is used to drive the swing rod 10 to swing back and forth in pitch under the action of the driving structure 20, and adjust the swing height of the swing rod 10. One end of the first connecting rod 40 is rotatably connected to the protruding end of the swing rod 10. One end of the rotating rod 50 is rotatably mounted on the frame 80, and the other end is rotatably connected to the first connecting rod 40, and the connection point between the rotating rod 50 and the first connecting rod 40 is located between the two ends of the first connecting rod 40. One end of the second connecting rod 60 is rotatably connected to one end of the first connecting rod 40. The weft pushing assembly 70 is rotatably mounted on the frame 80, and is rotatably connected to the other end of the second connecting rod 60, so as to swing back and forth under the pull of the second connecting rod 60.

[0024] When the first connecting rod 40 and the second connecting rod 60 are in the same line, the weft pushing assembly 70 pushes the weft to the limit position. Figure 2 When the first connecting rod 40 and the second connecting rod 60 are set to be collinear, the height of the position of the swing rod 10 is the first height. After the adjustment of the adjusting member 30, when the maximum swing height of the swing rod 10 is at the first height, the weft pushing assembly 70 performs one beating in one swing cycle. When the maximum swing height of the swing rod 10 is higher than the first height, the weft pushing assembly 70 performs two beatings in one swing cycle.

[0025] Compared with the prior art, the screen weaving device with adjustable beating times provided in this embodiment has a driving structure 20 that drives the first connecting rod 40 and the second connecting rod 60 to move through the adjusting member 30, thereby driving the weft pushing assembly 70 to swing back and forth, thereby ensuring stable beating work. The adjusting member 30 can adjust the swing height of the swing rod 10. When the maximum swing height of the swing rod 10 is the same as the first height, the swing rod 10 will pass through the first height once in one swing cycle, thereby ensuring that the weft pushing assembly 70 performs one beating work in one swing cycle. When the maximum swing height of the swing rod 10 is higher than the first height, the swing rod 10 will pass through the first height twice in one swing cycle, thereby ensuring that the weft pushing assembly 70 performs beating work on both sides in one swing cycle. The screen weaving device with adjustable picking times provided in this embodiment can adjust the maximum swing height of the swing rod 10 through the adjusting member 30, thereby realizing the change of the picking times of the weft pushing assembly 70 within one swing cycle, and can adapt to wefts of different diameters. At the same time, it can ensure that the wefts are pushed into place, and can effectively ensure the uniformity of the screen mesh, thereby ensuring the quality of the product, and has strong practicality.

[0026] In some embodiments, the rotation connection points among the swing rod 10, the first connecting rod 40, the rotating rod 50, the second connecting rod 60 and the weft pushing assembly 70 can be as follows: Figure 2 See the structure shown. Figure 2 , the direction of warp transmission is set as the first direction, and the horizontal direction perpendicular to the first direction is set as the second direction. The rotation axis of the swing rod 10, the rotation axis of the swing rod 10 and the first connecting rod 40, the rotation axis of the first connecting rod 40 and the second connecting rod 60, the rotation axis of the second connecting rod 60 and the weft pushing assembly 70, the rotation axis of the weft pushing assembly 70 and the frame 80, the rotation axis of the rotating rod 50, and the rotation axis of the rotating rod 50 and the first connecting rod 40 are all set along the second direction. This structure can ensure the stability of the force of the swing rod 10, the first connecting rod 40, the rotating rod 50, the second connecting rod 60 and the weft pushing assembly 70, and thus ensure the stable beating of the weft.

[0027] It should be noted that the frame 80 is provided with a plurality of rotating shafts for rotationally connecting the swing rod 10, the rotating rod 50 and the weft pushing assembly 70 respectively.

[0028] In some embodiments, the driving structure 20 may be configured as follows: Figure 1 See the structure shown. Figure 1The driving structure 20 includes a crankshaft 21, a connecting rod 22 and a driver 23. The crankshaft 21 is rotatably arranged on the frame 80, and the rotation axis is arranged along the second direction, and the crankshaft 21 has a transfer end. One end of the connecting rod 22 is rotatably connected to the transfer end of the crankshaft 21, and the other end of the connecting rod 22 is a mounting end rotatably connected to the adjusting member 30. The driver 23 is fixed on the frame 80, and the power output end is connected to the crankshaft 21. The crankshaft 21, the connecting rod 22, the adjusting member 30 and the rocker 10 are combined to form a four-bar structure, which can ensure that the rotational motion of the crankshaft 21 is converted into the swing of the rocker 10, thereby ensuring the beating work.

[0029] In some embodiments, the adjusting member 30 may be Figures 1 to 5 See the structure shown. Figures 1 to 5 The adjusting member 30 includes a first cylindrical portion 31, a second cylindrical portion 32 and a fixing pin. The first cylindrical portion 31 is rotatably connected to the swing rod 10, and the rotation axis is arranged along the second direction. The first cylindrical portion 31 is provided with a through hole 33, and the axis of the through hole 33 is arranged parallel to the axis of the first cylindrical portion 31. The second cylindrical portion 32 is fixedly connected to the first cylindrical portion 31, and the axis of the second cylindrical portion 32 is parallel to the axis of the first cylindrical portion 31 and is arranged at intervals. The second cylindrical portion 32 is rotatably connected to the mounting end, and the rotation axis is arranged along the second direction. The fixing pin passes through the swing rod 10 and enters the through hole 33 to fix the position of the second cylindrical portion 32 relative to the swing rod 10.

[0030] The swing rod 10 is provided with a cylindrical cavity 11 for the first cylindrical portion 31 to fit in and is provided with a plurality of positioning holes 12 communicating with the cylindrical cavity 11 . The positioning holes 12 are arranged in a ring shape around the axis of the cylindrical cavity 11 and at intervals.

[0031] The rotation of the first cylindrical portion 31 in the cylindrical cavity 11 and the fixing of the first cylindrical portion 31 by the fixing pin can ensure that the first cylindrical portion 31 moves synchronously with the swing rod 10 and the first cylindrical portion 31 will not rotate relative to the swing rod 10. The second cylindrical portion 32 is eccentrically arranged with the first cylindrical portion 31. At this time, due to the movement of the first cylindrical portion 31, the position of the second cylindrical portion 32 relative to the swing rod 10 will change. For example, when the highest position of the swing rod 10 is at the first height, the second cylindrical portion 32 is located in the middle position (initial position) in the width direction of the swing rod 10. At this time, the weft pushing assembly 70 can only perform one weft beating operation in one swing cycle; and when the first cylindrical portion 31 is rotated, the second cylindrical portion 32 can be adjusted to below the initial position. At this time, the highest height that the swing rod 10 can swing will exceed the first height. Therefore, in one swing cycle of the swing rod 10, it can pass through the first height position twice, thereby realizing two weft beating operations in one swing cycle of the weft pushing assembly 70. The arranged adjusting member 30 can be directly connected to the rocker arm 10 and the connecting rod 22, and its adjusting method is simple and convenient, and can directly adjust the number of times of beating the wefts, and can effectively adapt to wefts of different diameters. At the same time, the double beating method can also ensure that the wefts can be pushed into place, thereby ensuring the quality of the metal wire mesh, and the structure is simple, easy to manufacture, and highly practical.

[0032] In some embodiments, the adjusting member 30 may be Figure 4 See the structure shown. Figure 4 The diameter of the second cylindrical portion 32 is smaller than the diameter of the first cylindrical portion 31, and the second cylindrical portion 32 is spaced apart from the through hole 33. This structure can ensure that after the second cylindrical portion 32 is fixedly connected to the first cylindrical portion 31, interference between the second cylindrical portion 32 and the through hole 33 is prevented, and this structure is easy to manufacture and has strong practicality.

[0033] It should be noted that the first cylindrical portion 31 and the second cylindrical portion 32 may be an integrally cast structure.

[0034] In some embodiments, the swing rod 10 may be Figure 5 See the structure shown. Figure 5 The cylindrical cavity 11 is located between the two ends of the rocker rod 10 . This structure can ensure that the rocker rod 10 can be connected to the first connecting rod 40 , and the driving structure 20 will not interfere with the first connecting rod 40 .

[0035] In some embodiments, the weft pushing assembly 70 may be configured as follows: Figure 1 See the structure shown. Figure 1The weft pushing assembly 70 includes a swing frame 71 and a steel buckle 72. The bottom end of the swing frame 71 is rotatably connected to the frame 80. The steel buckle 72 is located at the top of the swing frame 71 and is arranged along the second direction, for each warp to pass through and for pushing the weft. The swing frame 71 and the steel buckle 72 can ensure the beating work. The swing frame 71 and the steel buckle 72 and the connection between the two can all adopt the existing technology, which will not be repeated here.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
