Description

Technical Field

[0001] The present application relates to the technical field of mesh bridge processing, and in particular to a mesh plate trimming device. Background Art

[0002] At present, the grid bridge has the characteristics of being able to be flexibly applied in the integrated wiring system. It can be used for upper and lower wiring of the bridge and is convenient for the maintenance of lines and equipment. Its own weight is only 1 / 5 of that of the traditional bridge. At the same time, the mesh structure makes its heat dissipation better and can effectively extend the service life of the cable.

[0003] The existing grid bridge generally includes a plurality of mutually parallel transverse ribs and a plurality of mutually parallel U-shaped longitudinal ribs, and the plurality of transverse ribs are distributed at intervals on the outside of the U-shaped structure. When processing this kind of grid bridge, it is generally necessary to first use automatic welding equipment to weld the transverse ribs and longitudinal ribs to form a mesh structure, and then cut off the longitudinal ribs on the mesh plate according to the model to be processed to obtain a mesh plate of suitable size; then, it is necessary to manually trim the mesh plate around, that is, manually trim the excess parts at both ends of the transverse ribs and longitudinal ribs to obtain a mesh plate of standard size; finally, the standard size mesh plate is bent into a grid bridge by an automatic bending machine, that is, the longitudinal ribs on the mesh plate are bent into a U-shaped structure. From the above content, it can be seen that the entire processing process of the grid bridge cannot be carried out on the same set of equipment, the processing steps are complicated, and manual trimming operations are required, the manual workload is large, and the work efficiency is low.

[0004] However, in order to realize automatic processing of the grid bridge, the prior art lacks a device for automatically trimming the mesh plate. Therefore, how to design an effective mesh plate trimming device is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0011] Preferably, the angle a is 70°.

[0012] Preferably, the trimming mechanism further comprises a collecting assembly, wherein the collecting assembly is disposed on the base, and the collecting assembly is used for collecting the fallen transverse ribs or the longitudinal ribs.

[0018] Compared with the prior art, the beneficial effect of the present application is that: since the conveying mechanism is used to convey the mesh in a direction parallel to the transverse ribs or in a direction parallel to the longitudinal ribs, correspondingly, the trimming mechanism is used to trim the two ends of the longitudinal ribs or the two ends of the transverse ribs; therefore, when the mesh is placed on the conveying mechanism and the transverse ribs are parallel to the conveying direction of the conveying mechanism, the conveying mechanism can convey the mesh in a direction parallel to the transverse ribs, and the two ends of the longitudinal ribs can be automatically trimmed by the trimming mechanisms on both sides of the conveying mechanism; similarly, when the mesh is placed on the conveying mechanism and the longitudinal ribs are parallel to the conveying direction of the conveying mechanism, the conveying mechanism can convey the mesh in a direction parallel to the longitudinal ribs, and the two ends of the transverse ribs can be automatically trimmed by the trimming mechanisms on both sides of the conveying mechanism.

[0041] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0043] Reference Figure 1-2 or Figure 6-7 An embodiment of the present application provides a trimming device for a mesh plate 100, comprising a conveying mechanism 2 and at least two trimming mechanisms 1, at least one trimming mechanism 1 being provided on each side of the conveying mechanism 2; the conveying mechanism 2 is used to convey the mesh plate 100 in a direction parallel to the transverse ribs 101 or in a direction parallel to the longitudinal ribs 102, and correspondingly, the trimming mechanism 1 is used to trim the two ends of the longitudinal ribs 102 or the two ends of the transverse ribs 101. That is to say, when the mesh plate 100 is placed on the conveying mechanism 2 and the transverse ribs 101 are parallel to the conveying direction of the conveying mechanism 2, the conveying mechanism 2 can convey the mesh plate 100 in a direction parallel to the transverse ribs 101, and the trimming mechanisms 1 on both sides of the conveying mechanism 2 can automatically trim the two ends of the longitudinal ribs 102; similarly, when the mesh plate 100 is placed on the conveying mechanism 2 and the longitudinal ribs 102 are parallel to the conveying direction of the conveying mechanism 2, the conveying mechanism 2 can convey the mesh plate 100 in a direction parallel to the longitudinal ribs 102, and the trimming mechanisms 1 on both sides of the conveying mechanism 2 can automatically trim the two ends of the transverse ribs 101; therefore, the mesh plate 100 can be automatically trimmed by the trimming device of the mesh plate 100, and the entire trimming process is simple to operate and has high work efficiency.

[0044] The present application does not limit the specific structure of the conveying mechanism 2, and only two specific structures are provided below (see Example 1 and Example 2 for details) for reference.

[0045] Example 1: Reference Figure 1-5The conveying mechanism 2 includes a first frame 20, a first track 21, a first positioning assembly 22 and a first pulling assembly 23. The first track 21, the first positioning assembly 22 and the first pulling assembly 23 are all arranged on the first frame 20; the first positioning assembly 22 is used to push the mesh plate 100 on the first track 21 to move in a direction parallel to the transverse ribs 101, and the second pulling assembly 27 is used to pull the mesh plate 100 to move in a direction parallel to the longitudinal ribs 102. When the mesh plate 100 is placed on the first track 21 and the longitudinal ribs 102 are parallel to the conveying direction of the conveying mechanism 2, the mesh plate 100 on the first track 21 is pushed to move in a direction parallel to the transverse ribs 101 by the first positioning assembly 22, so as to position the mesh plate 100 in a direction parallel to the transverse ribs 101, and then the mesh plate 100 is pulled to move in a direction parallel to the longitudinal ribs 102 by the first pulling assembly 23, so that the two ends of the transverse ribs 101 can be automatically trimmed by the trimming mechanisms 1 on both sides of the conveying mechanism 2.

[0046] Reference Figure 4 In the first embodiment, the first positioning assembly 22 includes a push plate 221 and a first telescopic member 222. The first telescopic member 222 is disposed on the first frame 20. The first telescopic member 222 is used to drive the push plate 221 to push the mesh plate 100 to move in a direction parallel to the transverse ribs 101. By arranging at least one such first positioning assembly 22 on both sides of the first track 21, the mesh plate 100 can be driven to be positioned in a direction parallel to the transverse ribs 101 by the first positioning assemblies 22 on both sides of the first track 21, and such a positioning structure is simple and easy to control. The first telescopic member 222 itself is a prior art, such as a cylinder, a hydraulic cylinder, etc.

[0047] Reference Figure 5 In the first embodiment, the first traction assembly 23 includes a support plate 231, a sliding seat 232, a driving member 233, a lifting member 234 and a clamping member 235. The support plate 231 is arranged on the first frame 20, and the sliding seat 232 is slidably connected to the support plate 231 in a direction parallel to the longitudinal ribs 102. The driving member 233 is arranged on the support plate 231, and the driving member 233 is used to drive the sliding seat 232 to slide; the clamping member 235 is connected to the sliding seat 232 through the lifting member 234. When the lifting member 234 drives the clamping member 235 to move upward, the clamping member 235 is used to clamp the transverse ribs 101, so that the screen 100 moves synchronously with the sliding seat 232, so as to realize the conveying of the screen 100 in a direction parallel to the longitudinal ribs 102. It should be noted that the sliding installation method of the sliding seat 232 is an existing technology, for example, sliding installation is achieved through a slider rail; the driving member 233 itself is also an existing technology, for example, it can be a conveyor belt, a screw drive mechanism, etc.; in addition, the lifting member 234 itself is an existing technology, such as a cylinder, a hydraulic cylinder, an electric telescopic rod, etc.

[0048] Reference Figure 1 as well as Figure 5 In the first embodiment, the clamping member 235 includes a bottom plate 2351 and two clamping arms 2352. The bottom plate 2351 is disposed at the upper end of the lifting member 234. The lower ends of the two clamping arms 2352 are spaced apart from each other on the bottom plate 2351 in a direction parallel to the longitudinal ribs 102. The spacing between the two clamping arms 2352 is adapted to the outer diameter of the transverse ribs 101, so that the transverse ribs 101 can be clamped between the two clamping arms 2352. The upper ends of the two clamping arms 2352 are suitable for setting chamfers or rounded corners, so that the spacing between the upper ends of the two clamping arms 2352 increases from bottom to top, so that the clamping can be clamped on the transverse ribs 101 more easily.

[0049] Reference Figure 2 as well as Figure 3 In the first embodiment, the first track 21 includes a conveying section 211 and a supporting section 212. The end of the conveying section 211 is connected to the starting end of the supporting section 212, so that the mesh plate 100 can be conveyed in a direction parallel to the longitudinal ribs 102 through the conveying section 211. When the mesh plate 100 moves to the end of the conveying section 211, the mesh plate 100 is pulled by the first traction assembly 23 to continue to move along the supporting section 212. Compared with directly pulling the mesh plate 100 by the first traction assembly 23, this arrangement is conducive to reducing the movement range of the first traction assembly 23. When the lifting member 234 is a cylinder or a hydraulic cylinder, it is necessary to connect the pipeline, and when the lifting member 234 is an electric telescopic rod, it is necessary to connect the power cord; therefore, when the movement range of the first traction assembly 23 is longer, the length of the pipeline or power cord that needs to be reserved is longer, and the wiring is more difficult; that is, when the movement range of the first traction assembly 23 is shorter, the length of the pipeline or power cord that needs to be reserved is shorter, and the wiring is simpler. The conveying section 211 is a belt conveying structure, and both ends of the supporting section 212 are suitable for bending downward.

[0050] It should be noted that the conveying mechanism 2 in Example 1 can also be used to convey the mesh plate 100 along a direction parallel to the transverse ribs 101. Specifically, when the directions of the longitudinal ribs 102 and the transverse ribs 101 on the mesh plate 100 in Example 1 are interchanged, it is equivalent to the conveying mechanism 2 conveying the mesh plate 100 along a direction parallel to the transverse ribs 101, so that the trimming mechanisms 1 on both sides of the conveying mechanism 2 can be used to trim the two ends of the longitudinal ribs 102 respectively.

[0051] Example 2: Reference Figure 6-13The conveying mechanism 2 includes a second frame 24, a second track 25, a second positioning assembly 26 and a second traction assembly 27. The second track 25 and the second traction assembly 27 are both arranged on the second frame 24, and the second positioning assembly 26 is arranged on the second track 25; when the mesh plate 100 moves to the second track 25, the second positioning assembly 26 is used to push the mesh plate 100 to move in a direction parallel to the longitudinal ribs 102 until the two ends of the longitudinal ribs 102 are respectively aligned with the two trimming mechanisms 1, and the second traction assembly 27 is used to pull the mesh plate 100 to move in a direction parallel to the transverse ribs 101, so that the two ends of the longitudinal ribs 102 can be trimmed respectively by the trimming mechanisms 1 on both sides of the conveying mechanism 2.

[0052] It should be noted that if Figure 7 and Figure 2 As shown, the specific structure of the second traction assembly 27 is the same as that of the first traction assembly 23, and will not be described in detail here.

[0053] Reference Fig.11 as well as Fig.12 In the second embodiment, the second track 25 is rotatably arranged on the second frame 24; when the screen 100 moves onto the second track 25, the second track 25 rotates upward to an inclined state, so that the screen 100 slides in a direction parallel to the longitudinal ribs 102 under the action of gravity until it contacts the second positioning assembly 26. In other words, under the action of the gravity of the screen 100 itself, the screen 100 can automatically slide to the side with the second positioning assembly 26, and then the screen 100 is pushed by the second positioning assembly 26 to position the screen 100 in a direction parallel to the longitudinal ribs 102. After positioning, the second track 25 is controlled to rotate downward again to a horizontal state, so that the screen 100 can be pulled by the second traction assembly 27 to move in a direction parallel to the longitudinal ribs 102. Through this unilateral positioning method, on the one hand, there is no need to set the second positioning components 26 on both sides of the second track 25, thereby reducing the number of second positioning components 26 and the difficulty of control; on the other hand, since the lengths of the longitudinal ribs 102 corresponding to different types of grid bridges are different, when processing different types of grid bridges, it is only necessary to adjust the spacing between the two opposite trimming mechanisms 1 without any adjustment of the second positioning components 26; otherwise, if the second positioning components 26 are set on both sides of the second track 25, when processing different types of grid bridges, since the length of the longitudinal ribs 102 on the mesh plate 100 has changed, it is necessary not only to adjust the spacing between the two opposite trimming mechanisms 1, but also to adjust the movement amplitude of the second positioning components 26 on at least one side of the second track 25 to adapt to the length change of the longitudinal ribs 102.

[0054] Reference Figure 3 , Fig.11 as well as Fig.12In the second embodiment, a baffle 251 is provided on one side of the second track 25. When the second track 25 is rotated upward to an inclined state, and the longitudinal ribs 102 slide in a direction parallel to the longitudinal ribs 102 under the action of gravity until they contact the baffle 251, the second positioning assembly 26 moves in a direction parallel to the longitudinal ribs 102 until they contact the transverse ribs 101. When the baffle 251 is not provided, due to the heavy weight of the mesh plate 100, when the mesh plate 100 automatically slides down under the action of gravity to contact with the second positioning assembly 26, it is bound to cause a large impact on the second positioning assembly 26, thereby easily reducing the positioning accuracy of the second positioning assembly 26 and shortening the service life of the second positioning assembly 26; however, under the action of the baffle 251, when the mesh plate 100 automatically slides down under the action of gravity, the longitudinal ribs 102 on the mesh plate 100 first contact the baffle 251, thereby limiting the mesh plate 100 from continuing to slide down, that is, after the impact of the mesh plate 100 is offset by the baffle 251, the second positioning assembly 26 is controlled to move in a direction parallel to the longitudinal ribs 102 until it contacts with the transverse ribs 101, so as to push the transverse ribs 101 (i.e., the mesh plate 100) to move in a direction parallel to the longitudinal ribs 102, thereby realizing positioning of the mesh plate 100 in a direction parallel to the longitudinal ribs 102. In addition, since the second positioning assembly 26 is used to push the transverse rib 101 to move, that is, the positioning is achieved through the outermost transverse rib 101 of the mesh plate 100, the positioning accuracy between the transverse rib 101 and the trimming mechanism 1 is improved, so that the trimming mechanism 1 can more accurately cut off the portion of the end of the longitudinal rib 102 that exceeds the transverse rib 101. In addition, when the second track 25 rotates downward to a horizontal state again, and the second traction assembly 27 pulls the mesh plate 100 to move in a direction parallel to the transverse rib 101, the second positioning assembly 26 moves away from the mesh plate 100 to prevent motion interference between the longitudinal rib 102 and the second positioning assembly 26.

[0055] Reference Figure 8 as well as Fig. 9 In the second embodiment, the second positioning assembly 26 includes a push rod 261 and a second telescopic member 262. The second telescopic member 262 is disposed on the second track 25. The second telescopic member 262 is used to drive the push rod 261 to move in a direction parallel to the longitudinal rib 102. Figure 6 As shown, since the push rod 261 needs to push the transverse rib 101, that is, the push rod 261 cannot contact the end of the longitudinal rib 102, under the action of the rod-shaped structure of the push rod 261, when the mesh plate 100 slides down, the probability of the end of the longitudinal rib 102 contacting the push rod 261 can be reduced. The second telescopic member 262 itself is a prior art, such as a cylinder, a hydraulic cylinder, etc.

[0056] Reference Figure 7 as well as Figure 8In the second embodiment, the conveying mechanism 2 further includes a pushing assembly 28 , which is disposed on the second track 25 , and is used to push the mesh plate 100 to move on the second track 25 in a direction parallel to the transverse ribs 101 . Even if the diameter of the push rod 261 is small, when the mesh plate 100 falls on the second track 25 in a bad position, the end of the longitudinal rib 102 may still contact the push rod 261 after the mesh plate 100 slides down, which may cause an operational failure and require manual intervention; however, under the action of the pushing assembly 28, even if the mesh plate 100 falls on the second track 25 in a bad position, the pushing assembly 28 can first push the mesh plate 100 to move on the second track 25 in a direction parallel to the transverse rib 101, so as to position the mesh plate 100 in a direction parallel to the transverse rib 101, and then control the second track 25 to rotate upward to an inclined state, thereby avoiding the end of the longitudinal rib 102 from contacting the push rod 261. In addition, it is also convenient to achieve the positioning between the mesh plate 100 (i.e., the longitudinal rib 102) and the second traction assembly 27.

[0057] Reference Figure 8 In the second embodiment, the pusher assembly 28 includes a pusher plate 281 and a third telescopic member 282. The third telescopic member 282 is disposed at the lower side of the second track 25 to avoid interference with the screen 100. The third telescopic member 282 is used to drive the pusher plate 281 to push the screen 100 to move on the second track 25 in a direction parallel to the transverse ribs 101. The pusher assembly 28 has a simple structure and is easy to control.

[0058] Reference Figure 8 , Fig.12 as well as Fig.13In the second embodiment, the conveying mechanism 2 further includes a clamping assembly 29, which is movably disposed on the second track 25; when the clamping assembly 29 moves downward to contact the mesh plate 100, it can limit the mesh plate 100 from moving on the second track 25 in a direction parallel to the longitudinal ribs 102. Since the second positioning assembly 26 only supports and positions the mesh plate 100 (i.e., the transverse ribs 101) on one side of the second track 25, when the second track 25 rotates back to a horizontal state, the second track 25 needs to rotate downward at a slow speed, otherwise the mesh plate 100 on the second track 25 will be displaced, thereby losing the positioning function. However, under the action of the clamping assembly 29, when the mesh plate 100 is positioned, the clamping assembly 29 is controlled to move downward until it contacts the mesh plate 100, thereby limiting the mesh plate 100 from moving on the second track 25 in a direction parallel to the longitudinal ribs 102. Even if the second track 25 rotates downward at a faster speed, it will not destroy the positioning of the mesh plate 100 in a direction parallel to the longitudinal ribs 102. Therefore, the accuracy of trimming the ends of the longitudinal ribs 102 by the trimming mechanism 1 can be ensured, and it is beneficial to improve work efficiency. Moreover, when the clamping assembly 29 clamps the mesh plate 100, the second positioning assembly 26 can move to separate from the mesh plate 100 to release the blocking effect of the second positioning assembly 26 on the longitudinal ribs 102. Then, when the second track 25 rotates back to a horizontal state, the second traction assembly 27 can immediately traction the mesh plate 100 to move in a direction parallel to the longitudinal ribs 102, further improving work efficiency. In addition, since the clamping assembly 29 only limits the displacement of the mesh plate 100 in a direction parallel to the longitudinal ribs 102, that is, it does not limit the movement of the mesh plate 100 in a direction parallel to the transverse ribs 101, during the trimming process, the mesh plate 100 is always clamped by the clamping assembly 29, thereby limiting the displacement of the mesh plate 100 in a direction parallel to the longitudinal ribs 102 during the trimming process, thereby ensuring the accuracy of trimming.

[0059] Reference Fig.10 In the second embodiment, the clamping assembly 29 includes a first frame 291, a second frame 292, a clamping wheel 293 and an elastic component 294. The first frame 291 can be movably arranged on the second track 25, and the second frame 292 can be slidably connected to the first frame 291; the elastic component 294 is arranged between the first frame 291 and the second frame 292, and the elastic component 294 forces the second frame 292 to slide downward relative to the first frame 291; the clamping wheel 293 can be rotatably connected to the second frame 292, and the axis of the clamping wheel 293 is parallel to the axis of the longitudinal rib 102, and the outer annular surface of the clamping wheel 293 is coaxially provided with an annular groove 2931 for accommodating the transverse rib 101. Fig.12 and Fig.13As shown, when the second frame 292 moves downward until the annular groove 2931 on the outer ring surface of the clamping wheel 293 contacts the transverse rib 101, the transverse rib 101 (i.e., the mesh plate 100) can be limited from being displaced in a direction parallel to the longitudinal rib 102, and when the mesh plate 100 moves in a direction parallel to the transverse rib 101, the transverse rib 101 can drive the clamping wheel 293 to rotate, i.e., there is rolling friction between the outer wall of the transverse rib 101 and the inner wall of the annular groove 2931, and the friction resistance is very small. In addition, under the action of the elastic component 294, on the one hand, there is sufficient buffering effect between the second frame 292 and the first frame 291, so that the clamping wheel 293 will not press the transverse rib 101 too tightly; on the other hand, as shown in FIG. Figure 6 As shown, even if the longitudinal rib 102 is above the transverse rib 101, when the mesh plate 100 moves in a direction parallel to the transverse rib 101 until the longitudinal rib 102 contacts the pressure wheel 293, the longitudinal rib 102 can also force the pressure wheel 293 (i.e., the second frame 292) to move upward, that is, the pressure wheel 293 will not block the longitudinal rib 102 (i.e., the mesh plate 100) from continuing to move; when the longitudinal rib 102 crosses the pressure wheel 293, the elastic component 294 will force the second frame 292 to move downward, so that the annular groove 2931 contacts the transverse rib 101 again. On this basis, by providing multiple clamping assemblies 29, or increasing the number of pressure wheels 293 on the second frame 292, it is ensured that when the longitudinal rib 102 moves to the position of the pressure wheel 293, there are still at least two annular grooves 2931 on the pressure wheels 293 that contact the transverse rib 101. It should be noted that the present application does not limit the vertically movable installation method of the first frame 291, the vertically slidable installation method of the second frame 292, and the rotatable installation method of the clamping wheel 293. Fig.10 As shown, the first frame 291 directly lifts the cylinder 295 installed on the second track 25; the clamping wheel 293 is rotatably installed on the second frame 292 through the axle 2932, and the axle 2932 penetrates the outside of the second frame 292, and a vertical groove 2911 is set on the first frame 291, so that the axle 2932 slides up and down and connects to the vertical groove 2911; when there is only one clamping wheel 293 on the second frame 292, the part of the axle 2932 that slides and connects to the vertical is not a circular structure. In addition, the elastic component 294 itself is a prior art, such as a spring, and the fixing method of the spring is also a prior art, such as welding, screw fixing, or hole fixing.

[0060] Reference Fig.14In the second embodiment, the conveying mechanism 2 further includes a flanging assembly 30, which includes a fixed frame 301, a conveying track 302 and a flipping member 303; the conveying track 302 is arranged on the fixed frame 301, and the conveying track 302 is used to convey the mesh 100; the flipping member 303 is rotatably arranged on the fixed frame 301 or the conveying track 302, and the rotation axis of the flipping member 303 is horizontally perpendicular to the movement direction of the mesh 100, and when the flipping member 303 clamps the mesh 100 on the conveying track 302 and flips 180°, the conveying track 302 then conveys the mesh 100 to the second track 25. Fig.16 and Fig.17 As shown, since the mesh plate 100 can be automatically conveyed by other conveying equipment, the transverse ribs 101 on the mesh plate 100 are usually above the longitudinal ribs 102. In order to ensure that the longitudinal ribs 102 on the mesh plate 100 on the second track 25 are above the transverse ribs 101, a flanging assembly 30 can be set between the conveying equipment and the second track 25, so that the mesh plate 100 is first conveyed to the flanging assembly 30 (i.e., the conveying track 302) by the conveying equipment, and then the mesh plate 100 is flipped 180° by the flipping member 303, and then the mesh plate 100 is continued to be conveyed to the second track 25 by the conveying track 302, that is, the longitudinal ribs 102 of the mesh plate 100 on the second track 25 are above the transverse ribs 101.

[0061] Reference Fig.15 In the second embodiment, the number of the conveying tracks 302 and the flipping members 303 is at least two, and each conveying track 302 and each flipping member 303 are alternately arranged along the conveying direction that is horizontally perpendicular to the conveying track 302. Through the multiple conveying tracks 302 and the multiple flipping members 303 arranged alternately, the stability of conveying and flanging the screen 100 can be improved, and the overall structural layout is more compact and reasonable. Among them, the conveying track 302 is a conveyor belt, which has a simple structure and is easy to operate.

[0062] Reference Fig.15 as well as Fig.16In the second embodiment, the flip member 303 includes a turntable 3031 and at least one clamping rod 3032. The turntable 3031 can be rotatably set on the fixed frame 301 or the conveying track 302. The rotation axis of the turntable 3031 is horizontally perpendicular to the movement direction of the mesh plate 100; one end of each clamping rod 3032 is arranged on the turntable 3031 at intervals along the circumference of the turntable 3031, and the interval between two adjacent clamping rods 3032 is greater than the thickness of the mesh plate 100. When the turntable 3031 rotates until one of the two adjacent clamping rods 3032 moves to the bottom of the conveying track 302 and the other clamping rod 3032 moves to the top of the conveying track 302, the mesh plate 100 on the conveying track 302 can enter between the two clamping rods 3032. At this time, the turntable 3031 is driven to rotate until the two clamping rods 3032 clamp the mesh plate 100 and flip it 180°. Then the mesh plate 100 falls back onto the conveying track 302 and can continue to be transported to the second track 25 through the conveying track 302.

[0063] Reference Fig.15 as well as Fig.16 In the second embodiment, the number of the clamping rods 3032 is at least two, and a V-shaped structure is formed between two adjacent clamping rods 3032. On the one hand, the distance between the distal ends of the two adjacent clamping rods 3032 is increased, so that the mesh 100 is convenient to move between the two adjacent clamping rods 3032; on the other hand, the distance between the proximal ends of the two adjacent clamping rods 3032 is reduced, so that during the flanging process of the mesh 100, the proximal ends of the two adjacent clamping rods 3032 can always support the mesh 100, which is equivalent to the mesh 100 rotating around the proximal ends of the two clamping rods 3032, thereby preventing the mesh 100 from shaking greatly during the flipping process.

[0064] Reference Fig.15 In the second embodiment, the flanging assembly 30 further includes a driving motor and a rotating shaft 304. The rotating shaft 304 is rotatably arranged on the fixed frame 301 or the conveying track 302, and the rotating disk 3031 is coaxially arranged on the rotating shaft 304. The driving motor is arranged on the fixed frame 301 or the conveying track 302, and the driving motor is used to drive the rotating shaft 304 to rotate. By driving the rotating shaft 304 to rotate by the driving motor, each rotating disk 3031 can be driven to rotate synchronously, and the structure is simple and easy to operate. Among them, the driving motor is not drawn in the drawings, and the output shaft of the driving motor can be directly connected to the rotating shaft 304 coaxially, and can also be connected to the rotating shaft 304 through a transmission mechanism.

[0065] Reference Fig.16 , Fig.17 as well as Fig.18In the second embodiment, when the flanging assembly 30, the second track 25 and the trimming mechanism 1 are located on a line, and the conveying track 302 conveys the mesh plate 100 to the second track 25 in a direction parallel to the longitudinal ribs 102, the second traction assembly 27 is arranged on the side of the second frame 24 away from the flanging assembly 30, and the two trimming mechanisms 1 are respectively arranged on both sides of the second traction assembly 27, and the second track 25 is horizontally rotatable on the second frame 24; when the mesh plate 100 moves onto the second track 25, the second track 25 is horizontally rotated 90° so that the two ends of the longitudinal ribs 102 are respectively aligned with the trimming mechanism 1. In this case, when the mesh plate 100 moves onto the second track 25, a unilateral positioning method can also be adopted, that is, when the mesh plate 100 moves onto the second track 25, the second track 25 rotates upward to an inclined state, so that the mesh plate 100 slides downward in a direction parallel to the longitudinal ribs 102 under the action of gravity, until the mesh plate 100 is positioned in a direction parallel to the longitudinal ribs 102 by the second positioning assembly 26, and then the second track 25 rotates horizontally 90° and rotates downward to a horizontal state, so that the two ends of the longitudinal ribs 102 are aligned with the trimming mechanism 1 respectively. It should be noted that when the second track 25 in the horizontal state is located below the conveying track 302, that is, the second track 25 does not interfere with the conveying track 302 when it rotates horizontally. At this time, there is no need to distinguish the order of the second track 25 rotating horizontally 90° and rotating downward to the horizontal state; however, when the second track 25 in the horizontal state is flush with the conveying track 302, the second track 25 will inevitably interfere with the conveying track 302 during the horizontal rotation. At this time, the second track 25 needs to first rotate horizontally 90° in an inclined state (that is, the end of the second track 25 close to the conveying track 302 is higher than the conveying track 302), and then rotate downward to the horizontal state to prevent the second track 25 from interfering with the conveying track 302.

[0066] It should be noted that the present application does not limit the vertical rotation installation method and the horizontal rotation installation method of the second track 25. Fig.11 as well as Fig.12As shown, a reduction motor 253 is vertically installed on the second frame 24, and a rotating frame 254 is installed on the output shaft of the reduction motor 253. The second track 25 can rotatably install the rotating frame 254 through a bearing (the axis of the bearing is in the horizontal direction) and a bearing seat. A driving cylinder 255 is also provided on the rotating frame 254. The telescopic end of the driving cylinder 255 is provided with a pin hole 256, and the pin hole 256 can be radially slidably connected to the bar hole 252 on the lower side of the second track 25 through a pin shaft; when the driving cylinder 255 is extended or shortened, the second track 25 can be driven to rotate upward or downward, and during the up and down rotation of the second track 25, the pin shaft slides adaptively in the bar hole 252 to avoid motion interference; when the reduction motor 253 drives the rotating frame 254 to rotate horizontally, the second track 25 can be driven to rotate horizontally.

[0067] In the second embodiment, in order to adapt to the mesh 100 with different lengths of longitudinal ribs 102, the trimming device of the mesh 100 further includes a support frame 4, and at least one trimming mechanism 1 can be slidably connected to the support frame 4 along a horizontal direction perpendicular to the movement direction of the mesh 100. By sliding to adjust the distance between the two opposite trimming mechanisms 1, the two ends of the longitudinal ribs 102 with different lengths can be trimmed. For example, referring to Figure 6 as well as Figure 7 , when the second positioning assembly 26 on one side of the second track 25 is used to position the screen 100 on one side, the position of the trimming mechanism 1 corresponding to one side of the second positioning assembly 26 can be fixed, so that only the trimming mechanism 1 on the other side needs to be slid and adjusted to adapt to the length change of the longitudinal rib 102. It should be noted that the sliding installation method between the trimming mechanism 1 and the support frame 4 is the existing technology, for example, the sliding limit is realized by the slide groove and the slide rail, and the trimming mechanism 1 is driven to slide by the screw drive mechanism.

[0068] It should be noted that the conveying mechanism 2 in the second embodiment can also be used to convey the mesh plate 100 along a direction parallel to the longitudinal ribs 102. Specifically, when the directions of the longitudinal ribs 102 and the transverse ribs 101 on the mesh plate 100 in the second embodiment are interchanged, it is equivalent to the conveying mechanism 2 conveying the mesh plate 100 along a direction parallel to the longitudinal ribs 102, so that the two ends of the transverse ribs 101 can be trimmed respectively by the trimming mechanisms 1 on both sides of the conveying mechanism 2.

[0069] Reference Figure 19-24 In some embodiments of the present application, the trimming mechanism 1 includes a base 11 and a shearing assembly 12. The shearing assembly 12 is disposed on the base 11. The shearing assembly 12 is used to trim the ends of the longitudinal ribs 102 or the ends of the transverse ribs 101. The angle a between the shearing surface of the shearing assembly 12 and the horizontal plane is 45°-90°. The following is a specific description of trimming the ends of the transverse ribs 101 as an example: Fig.24As shown, since the shearing surface of the shearing component 12 cannot shear the longitudinal rib 102, that is, the shearing surface of the shearing component 12 is at most tangent to the outer annular surface of the longitudinal rib 102, when the angle a is equal to 90°, the shearing surface is vertically tangent to the outer annular surface of the longitudinal rib 102, that is, the cross section of the transverse rib 101 is vertically tangent to the outer annular surface of the longitudinal rib 102; similarly, when the angle a is less than 90°, the shearing surface is inclined to be tangent to the outer annular surface of the longitudinal rib 102; regardless of whether the shearing surface is vertical or inclined to the longitudinal rib 102 The outer annular surface of the transverse rib 101 is tangent to the outer annular surface, and the portion of the end of the transverse rib 101 that exceeds the longitudinal rib 102 can be cut off as much as possible, so that the end of the transverse rib 101 does not exceed the outside of the longitudinal rib 102; however, when the angle a is less than 45°, that is, the portion of the transverse rib 101 located directly above the longitudinal rib 102 is cut off by at least half, which will reduce the strength of the end of the transverse rib 101, making it easy for the transverse rib 101 to fall off from the longitudinal rib 102; therefore, the suitable angle a is 45°-90°.

[0070] Reference Fig. 20 , Fig.23 as well as Fig.24 In some embodiments of the present application, the shearing assembly 12 includes a base 121, a support platform 122 and a cutter 123. The base 121 is disposed on the base 11, and the support platform 122 is disposed on the base 121; the cutter 123 is slidably disposed on the base 121, and the angle between the sliding direction of the cutter 123 and the horizontal plane is equal to the angle a. Taking trimming the end of the transverse rib 101 as an example, it is only necessary to prevent the portion of the end of the transverse rib 101 that needs to be trimmed from being between the cutter 123 and the support platform 122, and then by driving the cutter 123 to reciprocate once, the excess portion of the end of the transverse rib 101 can be cut off.

[0071] Reference Fig.23 as well as Fig.24In some embodiments of the present application, when the conveying mechanism 2 conveys the mesh 100 in a direction parallel to the longitudinal ribs 102, that is, when the ends of the transverse ribs 101 are trimmed, the transverse ribs 101 are located above the longitudinal ribs 102. Since the transverse ribs 101 are located above the longitudinal ribs 102, the longitudinal ribs 102 can be supported by the support platform 122, that is, during the shearing process, the transverse ribs 101 and the longitudinal ribs 102 are subjected to pressure, so the welding points between the transverse ribs 101 and the longitudinal ribs 102 will not fall off. Otherwise, when the transverse ribs 101 are located below the longitudinal ribs 102, during the shearing process, the transverse ribs 101 and the longitudinal ribs 102 are subjected to tension, which easily causes the welding points between the transverse ribs 101 and the longitudinal ribs 102 to fall off, thereby making the transverse ribs 101 and the longitudinal ribs 102 not firmly fixed. Similarly, when the conveying mechanism 2 conveys the screen 100 in a direction parallel to the transverse ribs 101 , that is, when the ends of the longitudinal ribs 102 are trimmed, the longitudinal ribs 102 are located above the transverse ribs 101 .

[0072] Reference Figure 20-24 In some embodiments of the present application, the angle a is less than 90°; the base 121 is slidably disposed on the base 11, and the sliding direction of the base 121 is perpendicular to the sliding direction of the cutter 123; the support platform 122 and the cutter 123 are staggered with each other, and a positioning groove 1221 is provided on the support platform 122; when the base 121 slides toward the upper side of the mesh plate 100, the distance between the support platform 122 and the mesh plate 100 gradually decreases until the positioning groove 1221 contacts an outer transverse rib 101 or a longitudinal rib 102, the positioning groove 1221 is used to limit the transverse rib 101 or the longitudinal rib 102, and the cutter 123 reciprocates once to trim the end of the transverse rib 101 or the end of the longitudinal rib 102. Taking trimming the transverse ribs 101 as an example, when the conveying mechanism 2 conveys the screen 100 in a direction parallel to the longitudinal ribs 102, the base 121 is first controlled to slide toward the lower side of the screen 100. Since the angle a is less than 90° and the sliding direction of the base 121 is perpendicular to the sliding direction of the cutter 123, the numerical gap between the support table 122 and the screen 100 will increase, that is, the upper end of the support table 122 will not contact the screen 100 (such as Fig.21 and Fig. 22As shown in the figure), the mesh plate 100 automatically moves with the conveying mechanism 2 to the top of the support; otherwise, if the support platform 122 is fixed, the vertical gap between the upper end of the support platform 122 and the mesh plate 100 is very small during the conveying of the mesh plate 100. Once the mesh plate 100 is bent downward under the action of its own gravity or other reasons, the longitudinal ribs 102 or the transverse ribs 101 on the mesh plate 100 are likely to cause motion interference with the support platform 122; when the transverse rib 101 moves to between the cutter 123 and the support platform 122, the base 121 is controlled to slide toward the upper side of the mesh plate 100 until the positioning groove 1221 contacts one of the outer longitudinal ribs 102 (as shown in the figure). Fig.23 and Fig.24 As shown in FIG. 1 , the positioning groove 1221 just limits the longitudinal rib 102, which can not only improve the shearing accuracy, but also prevent the longitudinal rib 102 from being displaced during the shearing process; finally, the cutter 123 is controlled to reciprocate once to cut off the redundant part at the end of the transverse rib 101. According to experiments, the comprehensive effect is best when the angle a is 70°.

[0073] The present application does not limit the sliding installation method of the base 121 and the sliding installation method of the cutter 123. For example, Fig. 20 , Fig.21 as well as Fig.23 As shown, the shearing assembly 12 also includes a fixed plate 124, a guide column 125, a return spring 126, a telescopic cylinder 127 and a hydraulic cylinder 128. The base 121 realizes sliding limitation with the base 11 through a slider rail, and drives the base 121 to slide back and forth through the telescopic cylinder 127; the cutter 123 is arranged above the base 121 through the fixed plate 124, and a guide column 125 is arranged at the lower end of the fixed plate 124. The guide column 125 is slidably connected to the column hole on the base 121 along the movement direction of the cutter 123; the return spring 126 is sleeved on the guide column 125, and the return spring 126 forces the fixed plate 124 to move upward; a hydraulic oil cylinder 128 is installed above the fixed plate 124. Cylinder 128, the telescopic end of the hydraulic cylinder 128 is in contact with the fixed plate 124; when the telescopic cylinder 127 drives the base 121 to slide toward the lower side of the mesh plate 100, the hydraulic cylinder 128 contracts upward to prevent interference between the hydraulic cylinder 128 and the fixed plate 124; when the telescopic cylinder 127 drives the base 121 to slide toward the upper side of the mesh plate 100 until the positioning groove 1221 contacts the corresponding longitudinal rib 102 (or transverse rib 101), the hydraulic cylinder 128 extends downward to drive the fixed plate 124 (i.e., the cutter 123) to move downward. After shearing, the hydraulic cylinder 128 contracts upward, and the return spring 126 forces the fixed plate 124 to return upward.

[0074] Reference Fig. 20 as well as Fig.23In some embodiments of the present application, the trimming mechanism 1 further includes a collecting assembly 13, which is disposed on the base 121 and is used to collect the fallen transverse ribs 101 or longitudinal ribs 102. Under the action of the collecting assembly 13, after the ends of the transverse ribs 101 or the ends of the longitudinal ribs 102 are trimmed, the fallen ends of the transverse ribs 101 or longitudinal ribs 102 can be collected by the collecting assembly 13 for easy sorting.

[0075] Reference Fig. 20 , Fig.21 as well as Fig.23 In some embodiments of the present application, the collecting assembly 13 includes a baffle plate 131 and a discharge hopper 132, the baffle plate 131 is arranged on the base 121, and a collection area for collecting fallen transverse ribs 101 or longitudinal ribs 102 is formed between the baffle plate 131 and the support platform 122; the discharge hopper 132 is arranged on the base 11, the upper end cover of the discharge hopper 132 is arranged at the lower end of the collection area, and the lower end of the discharge hopper 132 extends to the outside of the base 11, so that the transverse ribs 101 or longitudinal ribs 102 in the collection area are discharged to the outside of the base 11 through the discharge hopper 132 under the action of gravity. The collection area formed between the baffle plate 131 and the support platform 122 can collect the fallen transverse ribs 101 or longitudinal ribs 102. Under the action of gravity, the transverse ribs 101 or longitudinal ribs 102 in the collection area can be discharged to the outside of the base 11 through the discharge hopper 132, so that a collection bucket or collection basket can be placed below the lower port of the discharge hopper 132 for collection. The discharge hopper 132 can be tilted downward to any direction to avoid mutual interference with other structures. In addition, since the upper end of the discharge hopper 132 is covered at the lower end of the collection area, even after the base 121 slides, the upper end of the discharge hopper 132 can still cover the lower end of the collection area.

[0076] Reference Figure 1 as well as Figure 19-24 In some embodiments of the present application, the trimming mechanism 1 further includes a supporting plate 14 and a pressing plate 15; the supporting plate 14 is horizontally arranged on the base 11, and the supporting plate 14 is arranged on both sides of the support platform 122 along the movement direction of the mesh 100; the pressing plate 15 is arranged on the base 11, and a gap for the mesh 100 to pass through is reserved between the pressing plate 15 and the supporting plate 14. The supporting plate 14 supports the mesh 100 transported by the conveying mechanism 2, preventing the outer side of the mesh 100 from bending downward under the action of gravity; the pressing plate 15 presses the mesh 100, preventing the mesh 100 from bouncing upward after shearing, thereby improving the movement accuracy of the mesh 100 on the conveying mechanism 2 (i.e., the positioning accuracy between the mesh 100 and the trimming mechanism 1).

[0077] Reference Figure 1 , Fig.19 as well as Fig. 20 In some embodiments of the present application, the pressing plate 15 can be slidably arranged on the base 11 up and down. By sliding the pressing plate 15 up and down, the size of the gap between the pressing plate 15 and the supporting plate 14 can be adjusted to accommodate the passage of mesh plates 100 of different thicknesses. The present application does not limit the upward and downward sliding installation method of the pressing plate 15. For example, the trimming mechanism 1 also includes a fixed block 16, a screw 17 and a nut 18. The fixed block 16 is arranged on the side of the base 11, and the fixed block 16 is penetrated with mounting holes up and down; the upper end of the pressing plate 15 is connected to the screw 17, and the upper end of the screw 17 penetrates the mounting hole. At least one nut 18 is threadedly connected to the screw 17 and located on the upper and lower sides of the fixed block 16. By rotating the nut 18, the height of the pressing plate 15 can be adjusted by sliding up and down.

[0078] Reference Figure 1 , Fig.19 as well as Fig. 20 In some embodiments of the present application, one end of the support plate 14 away from the support platform 122 is bent downward to form an inclined portion 141. Since the outer side of the mesh plate 100 is easily bent downward under the action of gravity, if there is no effect of the inclined portion 141, the mesh plate 100 and the support plate 14 are easily interfered with each other; however, under the action of the inclined portion 141, even if the outer side of the mesh plate 100 is bent downward, it will gradually move along the inclined portion 141 to the support plate 14.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
