[0002] Mesh is an essential material used in fields such as partition nets, wall nets, protective nets, shelf nets, pet cages, etc., and has a very wide range of uses.

[0003] When manufacturing mesh, it is necessary to first form the frame, and then combine and weld the frame with the internal strip again.

[0004] Existing mesh processing generally requires multiple devices to complete. That is, the strip for forming the frame needs to be bent on a bending machine first. After bending, it is transferred to a welding machine for butt welding and forming. Finally, it can be sent to a mesh processing device to be combined and welded with the internal strip. The whole process is cumbersome and complex, time-consuming and laborious, which directly affects the efficiency of mesh processing. Summary of the Invention

Specific embodiments

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

[0047] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0048] As Figures 1-14 shown, a reciprocating mesh processing device successively includes a welding mechanism 1, a front conveying mechanism 2, a mold exchanging mechanism 3, and a frame forming mechanism 4 from front to back. A discharging mechanism 5 capable of moving horizontally is arranged above the front conveying mechanism 2; a feeding mechanism 6 capable of moving horizontally and a rear conveying mechanism 7 capable of moving vertically are arranged above the mold exchanging mechanism 3; a feeding mechanism 8 is arranged on at least one side of the mold exchanging mechanism 3; the frame forming mechanism 4 includes a feeding component I, a bending component, and a butt welding component.

[0049] Among them, the frame forming mechanism 4 is used for forming the frame, including feeding, bending, and butt welding of the strip I for forming the frame; the feeding mechanism 8 is used for feeding the strip II inside the mesh; the feeding mechanism 6 is used for feeding the strip II; the rear conveying mechanism 7 is used for transferring the formed frame to the mold exchanging mechanism 3; the mold exchanging mechanism 3 is used for combining the frame and the strip II; the front conveying mechanism 2 is used for transferring the combined frame and strip II to the welding mechanism 1; the welding mechanism 1 is used for completing the welding of the frame and the strip II.

[0050] The frame forming mechanism 4 includes a frame I 41 for installing the feeding component I, the bending component, and the butt welding component.

[0051] In order to be able to feed the strip II to the feeding component I, the frame forming mechanism 4 further includes a material trough 42.

[0052] Specifically, the material trough 42 is arranged horizontally, and its two ends are detachable movable baffles, and the position of the movable baffle can be adjusted according to the length of the strip I to adapt to the placement of strips I of different lengths.

[0053] In order to be able to complete the feeding of the strip I, the feeding component I includes a material suction seat 43 installed with a magnetic part I (not shown in the figure) at the bottom and capable of moving up and down and longitudinally. The material suction seat 43 can transfer the strip I in the material trough 42 to the bending component.

[0054] Specifically, a horizontal material suction groove I 44 is arranged at the bottom of the material suction seat 43, and the magnetic part I is installed in the installation hole in the material suction groove I 44. The strip I can be adsorbed from the material trough 42 through the magnetic part I.

[0055] Preferably, the magnetic part I can be selected as a strong magnet, which can effectively ensure the adsorption effect of the strip I.

[0056] Preferably, a detecting member I 45 is provided at one end of the material suction base 43 for detecting whether the material strip I is adsorbed to the bottom of the material suction base 43.

[0057] The feeding assembly I further includes a mounting plate I 46 located above the material suction base 43. Pushing plates 47 are provided below both ends of the mounting plate I 46, and a material suction cylinder I 48 is fixed on the mounting plate I 46. The piston rod of the material suction cylinder I 48 passes through the mounting plate I 46 downward and is connected to the material suction base 43.

[0058] A sliding plate 49 is provided above the mounting plate I 46, and a lifting cylinder I 410 with a piston rod connected to the mounting plate I 46 is mounted on the sliding plate 49. A longitudinal synchronous belt I 411 is also mounted on the frame I 41. The sliding plate 49 is connected to the synchronous belt I 411, and a synchronous wheel located at the rear end of the synchronous belt I 411 is drivingly connected to a motor I 412.

[0059] The feeding process of the material strip I is as follows: The material suction base 43 moves above the material trough 42, the lifting cylinder I 410 drives the material suction base 43 to move downward, and then the material suction cylinder I 48 drives the material suction base 43 to continue moving downward and extends into the material trough 42 to suck the material strip I. After the material strip I is successfully adsorbed, the lifting cylinder I 410 drives the material suction base 43 to rise, and the motor I 412 drives the material suction base 43 to move above the bending assembly through the synchronous belt I 411. Then the lifting cylinder I 410 drives the material suction base 43 to descend. After descending in place, the material suction cylinder I 48 drives the material suction base 43 to rise alone. During this rising process, the material strip I is separated from the material suction base 43 by the blocking of the pushing plate 47 and falls into the bending assembly. At this time, the lifting cylinder I 410 drives the material suction base 43 to rise again and moves to above the material trough 42 through the synchronous belt I 411, facilitating the next suction operation of the material strip I.

[0060] Preferably, a slide rail I for guiding the sliding plate 49 is provided on the frame I 41.

[0061] In this embodiment, the frame is a rectangular structure with four bending corners. Therefore, four bending assemblies are arranged side by side and are located on the front side of the material trough 42.

[0062] To complete the bending of the material strip I, the bending assembly includes a fixed block 413, a bending column 414 that rotates around the fixed block 413, and a pressing block 415 that can move forward and is located behind the fixed block 413.

[0063] The bending assembly further includes a bending seat 416. A central shaft 417 is installed in the bending seat 416, and a rotating sleeve 418 is sleeved outside the central shaft 417. The fixed block 413 is installed at the top of the central shaft 417, and the bending column 414 is installed at the top of the rotating sleeve 418.

[0064] The briquetting block 415 is slidably arranged in a guiding seat 419. The guiding seat 419 is fixed on the bending seat 416. A pressing air cylinder 420 connected to the briquetting block 415 is installed at the rear side of the guiding seat 419.

[0065] A gear 421 is installed at the lower end of the rotating sleeve 418. A rack 422 is meshed with the outer side of the gear 421. The rear end of the rack 422 is connected with a bending air cylinder 423.

[0066] The strip I is located between the fixed block 413 and the bending column 414 and is bent by the rotation of the bending column 414. Before bending, the lateral position of the strip I needs to be adjusted. At one end of the feeding position of the bending assembly, a pushing baffle installed on the frame I 41 is provided, and a fixed baffle is installed at the other end. A pushing air cylinder 54 is arranged on the outer side of the pushing baffle.

[0067] Preferably, the bending air cylinder 423 is a double-piston-rod air cylinder. The piston rod at its front end is connected with the rack 422, and a limiting block 424 is installed on the piston rod at its rear end. By adjusting the position of the limiting block 424, the telescopic degree of the piston rod at the front end can be adjusted, and then the rotation angle of the bending column 414 can be adjusted to achieve the effect of adjusting the bending angle.

[0068] In this embodiment, the two outer bending angles located on the outer side are bent first, and then the two inner bending angles located on the inner side are bent. During this process, the fixed block 413 for bending the outer bending angle will block the bending of the inner bending angle. Therefore, in the two bending assemblies located on the outer side, the fixed block 413 can move up and down.

[0069] A lifting air cylinder II 425 with the top end of the piston rod connected to the lower end of the central shaft 417 is installed below the bending seat 416. At this time, the central shaft 417 can also axially move in the rotating sleeve 418.

[0070] Preferably, a horizontal slide rail II is arranged on the frame I 41, and the front end and the rear end of the bending seat 416 are both slidably fitted on the slide rail II, and the positions of the respective bending assemblies can be adjusted as needed to adapt to the bending of frames of different specifications.

[0071] The bending process of strip I is as follows: The loading component I transfers strip I to between the fixed block 413 and the bending column 414, and the bending column 414 is located at the rear side of strip I, and the pressing block 415 is also located at the rear side of strip I. At this time, the two bending components on the outer side first perform the bending operation. The pressing cylinder 420 pushes the pressing block 415 forward to cooperate with the fixed block 413 to clamp strip I. At this time, the piston rod at the front end of the bending cylinder 423 indirectly drives the bending column 414 to rotate relative to the fixed block 413 to bend strip I forward, forming two outer bending angles. After the outer bending angles are bent, the lifting cylinder II 425 drives the central shaft 417 to move downward so that the fixed block 413 retracts into the rotating sleeve 418. At this time, the two bending components on the inner side can install the above bending action to perform the bending operation of the two inner bending angles.

[0072] After bending is completed, the two endpoints of strip I are directly located in the butt welding component, and the butt welding operation can be directly performed.

[0073] To complete the butt welding of the two endpoints of strip I, the butt welding component is located in front of the bending component and includes two pairs of electrode blocks 426 arranged in a front-back correspondence. The two electrode blocks 426 on the front side can move synchronously up and down and longitudinally, and one pair of electrode blocks 426 can move towards the other pair of electrode blocks 426.

[0074] One of the two pairs of electrode blocks 426 is located on the movable side of the butt welding component, and the other pair is located on the fixed side of the butt welding component.

[0075] After bending, the two endpoints of strip I are located between the two pairs of electrode blocks 426 and are fixed and butt welded by the movement of the electrode blocks 426.

[0076] After bending, the front side of strip I is set horizontally, and its endpoints are located between the two pairs of electrode plates. The two electrode blocks 426 on the front side can move up and down. This is to avoid the two electrode blocks 426 blocking strip I when they move downward during bending, and then rise again to face the two electrode blocks 426 on the rear side during butt welding, facilitating the subsequent fixation of the end of strip I.

[0077] The two electrode blocks 426 on the front side can move backward synchronously to cooperate with the two electrode blocks 426 on the rear side to clamp the end of strip I and fix the strip.

[0078] The two electrode blocks 426 on the movable side move synchronously towards the fixed side to make the two endpoints of strip I contact, and butt welding is achieved after the electrode blocks 426 are powered on.

[0079] The butt welding assembly further includes two support frames 427 and two upper pressing arm electrode fixing plates 428. A swing cylinder 429 is installed at the bottom of the support frame 427. The front end of the piston rod of the swing cylinder 429 is hinged to the bottom of the corresponding upper pressing arm electrode fixing plate 428. A support plate 430 that is movably matched with the support frame 427 is arranged on the upper part of the upper pressing arm electrode fixing plate 428. The two electrode blocks 426 on the front side are respectively fixed on the tops of the two upper pressing arm electrode fixing plates 428.

[0080] An elevating cylinder III 431 is arranged on the outer side of the support frame 427 and is connected thereto.

[0081] Preferably, a detecting member II 432 is installed on the outer side of the elevating cylinder III 431 on the fixed side for detecting the telescopic degree of the piston rod of the elevating cylinder III 431.

[0082] The butt welding assembly further includes a fixed seat I 433 and two support plates 434 installed on the front side of the fixed seat I. The support plate 434 on the movable side is in transverse sliding fit on the fixed seat I, while the support plate 434 on the fixed side is fixedly installed on the fixed seat I. The elevating cylinder III 431 on the movable side is installed on the support plate 434 on its side, and the elevating cylinder III 431 on the fixed side is installed on the fixed seat I.

[0083] The two electrode blocks 426 on the rear side are installed on two conductive bars 435, and the conductive bars 435 are fixed on the corresponding support plates 434.

[0084] In order to provide power for the movement of the two electrode blocks 426 on the movable side, a translation cylinder 436 is connected to the outer side of the support plate 434 on the movable side.

[0085] In order to facilitate the placement of the bent strip I, a placing plate 441 is arranged on the fixed seat I 433.

[0086] Preferably, in order to ensure the accuracy of the relative positions of the ends of the strip I, positioning plates 437 with V-shaped positioning openings at the front ends are arranged between and on the outer sides of the two electrode blocks 426 on the rear side, and a positioning cylinder 438 is arranged on the rear side of the positioning plate 437 between the two electrode blocks 426.

[0087] In order to be able to conduct electric welding, the frame forming mechanism 4 further includes a power source connected to the two electrode blocks 426 on the rear side.

[0088] The lower end of the conductive bar 435 is connected to a wiring row that passes through the fixed seat I 433 backward. A power source installed in the frame I 41 is arranged on the rear side of the fixed seat I 433. The wiring row is connected to the power source through a copper braided wire, facilitating the electrode blocks 426 to be connected to the power source to realize the welding of the ends of the strip I.

[0089] Preferably, a slide seat I 439 with a longitudinal slide rail III and a longitudinal adjustment screw installed inside is arranged below the fixed seat I 433, and a slide seat II 440 with a transverse slide rail III and a transverse adjustment screw installed inside is arranged below the slide seat I 439. Through the arrangement of the two slide seats, the transverse and longitudinal random movement of the butt-welding assembly can be realized to adapt to the butt-welding of frames with different specifications.

[0090] Both the slide seat I 439 and the slide seat II 440 adopt, but are not limited to, the cooperation of the adjustment screw and the slide rail III.

[0091] The butt-welding process of the strip I is as follows: when the bending is completed, the height of the front electrode block 426 is lower than that of the rear electrode block 426. At this time, the three positioning plates 437 position the two ends of the strip I. The lifting cylinder III 431 drives the two front electrode blocks 426 to rise so that they are opposite to the two rear electrode blocks 426. Then, the swing cylinder 429 pushes the top of the upper pressure arm electrode fixing plate 428 to swing backward, thereby driving the two front electrode blocks 426 to move backward so that they cooperate with the two rear electrode blocks 426 to clamp the two ends of the strip I. At this time, the positioning cylinder 438 drives the middle positioning plate 437 to move backward, and the translation cylinder 436 pushes the two electrode blocks 426 on the movable side to move towards the fixed side so that the two endpoints of the strip I are in contact, and the conductive bar 435 is energized to realize the butt-welding of the endpoints of the strip I.

[0092] In order to improve the processing efficiency and enable the loading and assembly of another mesh while welding one mesh, a mold exchange mechanism 3 is provided to complete the alternating work of the two molds 318.

[0093] The mold exchange mechanism 3 includes two exchange seats 31 arranged in an upper and lower stacked manner and capable of synchronous lifting, and a mold rack 32 with a mold 318 fixed inside is installed on the exchange seat 31.

[0094] The mold 318 exchange assembly includes a frame II 33, and the exchange seat 31 is arranged inside the frame II 33.

[0095] A longitudinal slide rail IV 34 is arranged on the exchange seat 31, and rollers 35 cooperating with the slide rail IV 34 are installed on both sides of the mold rack 32 to facilitate the movement of the mold rack 32.

[0096] Support frames 36 are arranged below the two exchange seats 31, and a synchronous lifting assembly is arranged below the support frames 36 to realize the synchronous lifting of the two exchange seats 31.

[0097] The mold 318 hook 317 synchronous lifting assembly includes a lifting cylinder IV37 installed on the frame II33 and located below the support frame 36, and vertical synchronous guide rods 38 are arranged at the four corners below the support frame 36. The lower end of the synchronous guide rod 38 passes through four guide blocks 39, and a synchronous connecting rod 310 is connected between adjacent guide blocks 39. Through the arrangement of the synchronous guide rod 38 and the synchronous connecting rod 310, the synchronization and stability of the exchange seat 31 during lifting and lowering can be guaranteed.

[0098] When the mold 318 is exchanged, in order to position the reset mold frame 32, a positioning component is installed on the rear side of the exchange seat 31.

[0099] The positioning assembly includes a fixing seat II 311 and a mounting plate II 312 mounted on the fixing seat II 311 . A magnetic plate 313 is arranged on the front side of the mounting plate II 312 , and a buffer spring 314 is installed between the mounting plate II 312 and the fixing seat II 311 .

[0100] Specifically, a mounting block 319 is fixed to the front side of the mounting plate II 312, and a groove is opened on the front side of the mounting block 319, and the magnetic plate 313 is installed in the groove to prevent the mold frame 32 from being damaged by impact when it is reset.

[0101] The mounting plate II 312 is connected to the fixing seat II 311 by bolts. The bolts pass through the fixing seat II 311 and are threadedly matched with the mounting plate II 312. The buffer spring 314 is sleeved on the bolts and is located between the fixing seat II 311 and the mounting plate II 312, so as to play a buffering role during positioning.

[0102] A detection member III315 is provided on one side of the mounting plate II312 for detecting whether the mold frame 32 has moved into place.

[0103] Preferably, the magnetic plate 313 can be made of a strong magnet.

[0104] A limit plate 316 corresponding to the magnetic plate 313 is provided on the rear side of the mold frame 32. After the mold frame 32 moves back to the corresponding exchange seat 31, when it moves into place, the limit plate 316 will be adsorbed on the magnetic plate 313 to ensure the stability of the mold frame 32 when it is in place.

[0105] A U-shaped hook 317 is provided on the front side of each mold 318 frame 32.

[0109] The traction assembly includes a traction connecting rod 22 and L-shaped hanging rods 23 installed at both ends of the traction connecting rod 22 and cooperating with the hooks 317.

[0110] A longitudinal synchronous belt Ⅱ24 is arranged on the frame Ⅲ21. The synchronous pulley at the rear end of the synchronous belt Ⅱ24 is installed on the frame Ⅱ33, and the synchronous pulley is connected to a motor Ⅱ (not shown in the figure). The motor Ⅱ drives the synchronous belt Ⅱ24 to rotate, so as to realize the forward and backward movement of the traction assembly.

[0111] The process of the mold 318 being exchanged and entering the welding mechanism 1 of the welding machine 11 is as follows: taking the upper mold 318 being loaded first as an example, the rear conveying mechanism 7 transfers the formed frame to the upper mold 318, and the loading mechanism 6 also transfers the strip Ⅱ to the upper mold 318, so that the frame and the strip Ⅱ are combined in the upper mold 318. At this time, the lifting cylinder Ⅳ37 drives the exchange seat 31 to move downwards, so that the hook 317 of the upper mold frame 32 is hooked to the hanging rod 23. The motor Ⅱ drives the upper mold frame 32 to move from the corresponding slide rail Ⅳ34 to the slide rail Ⅴ through the synchronous belt Ⅱ24 and the traction assembly, and then continues to move into the welding mechanism 1 of the welding machine 11 for welding operation.

[0112] Meanwhile, the lifting cylinder Ⅳ37 drives the exchange seat 31 to rise, then the lower mold 318 is loaded. When the loading of the lower mold 318 is completed, the mesh on the upper mold 318 has been welded successfully and is moved to the unloading station on the front conveying mechanism 2 under the drive of the traction assembly, and the unloading mechanism 5 unloads it from the upper mold 318. At this time, the upper mold 318 becomes an empty mold.

[0113] The upper mold frame 32 continues to move backward. When it moves to the front side of the mold exchange mechanism 3, the lifting cylinder Ⅳ37 drives the exchange seat 31 to descend, and the traction assembly continues to drive the upper mold frame 32 to move back into its exchange seat 31 and is stably positioned by the positioning assembly at the rear side of the exchange seat 31. Then the lifting cylinder Ⅳ37 drives the exchange seat 31 to rise again, so that the hanging rod 23 is disengaged from the hook 317 of the upper mold frame 32 and is hooked to the hook 317 of the lower mold frame 32. At this time, the traction assembly drives the lower mold frame 32 to move into the welding mechanism 1 of the welding machine 11 for welding, and at this time, the upper mold 318 can be loaded.

[0114] The two-layer molds 318 alternate between welding and loading operations, improving the processing efficiency.

[0115] To ensure that the mold 318 can fully enter the welding mechanism 1 of the welding machine 11, the synchronous pulley at the front end of the synchronous belt II 24 is located on the side of the welding mechanism 1 of the welding machine 11.

[0116] To transfer the formed frame to the mold 318 on the mold exchange mechanism 3, the rear conveying mechanism 7 includes a carriage I 71 that can move longitudinally, and two pairs of pneumatic fingers 72 that are arranged side by side under the carriage I 71 and can move up and down. The pneumatic fingers 72 can transfer the material frame on the butt welding assembly to the mold exchange mechanism 3.

[0117] To achieve the above effects, the rear end of the frame II 33 extends into the frame I 41.

[0118] A material transfer plate 73 is provided at the bottom of the carriage I 71, and the material transfer plate 73 is connected to the lower end of the piston rod of the lifting cylinder V 74 fixed to the lower end of the carriage I 71.

[0119] Horizontal slide bars 75 are provided on the front and rear sides of the material transfer plate 73. The pneumatic fingers 72 are slidably mounted on the slide bars 75 through sliding seats 76, and the positions of the two pairs of pneumatic fingers 72 can be adjusted according to the specifications of the frame, so as to facilitate the transfer of frames of different specifications.

[0120] The rear conveying mechanism 7 is directly mounted on the frame II 33. A longitudinal synchronous belt III 77 is provided on the frame II 33, and the carriage I 71 is connected to the synchronous belt III 77. The synchronous pulley at the front end of the synchronous belt III 77 is drivingly connected to a motor III 78.

[0121] Longitudinal slide rails VI 79 that cooperate with both ends of the carriage I 71 are also provided on the frame II 33.

[0122] The process of transferring the frame is as follows: The motor III 78 drives the carriage I 71 to move backward to the position of the butt welding assembly through the synchronous belt III 77. The lifting cylinder V 74 drives the pneumatic fingers 72 to move downward to clamp both sides of the frame. At this time, the lifting cylinder V 74 drives the pneumatic fingers 72 to rise, and drives the carriage I 71 to move forward to above the mold exchange mechanism 3 through the motor III 78 and the synchronous belt III 77. Then the lifting cylinder V 74 drives the pneumatic fingers 72 to move downward again, and the pneumatic fingers 72 release and place the frame in the mold 318.

[0123] Since there are material strips II in two directions inside the mesh sheet, in this embodiment, the feeding mechanism 6 is a double-sided feeding mechanism, that is, the feeding mechanism 6 includes two feeding components II. One feeding component II is used for feeding the longitudinal material strip II, and the other feeding component II is used for feeding the transverse material strip II.

[0124] The feeding mechanism 6 includes a frame IV 61 spanning across the frame II 33, and the two feeding components II can move horizontally on the frame IV 61.

[0125] The feeding component II includes a material suction plate 62 with a magnetic part II (not shown in the figure) installed at the bottom. The material suction plate 62 can transfer the strip II in the feeding mechanism 8 to the mold exchange mechanism 3.

[0126] A plurality of parallel material suction grooves II 63 are arranged at the bottom of the material suction plate 62, and magnetic parts II are installed in the mounting holes of each material suction groove II 63, and the strip II is adsorbed through the magnetic parts II.

[0127] The directions of the material suction grooves II 63 in the two feeding components II correspond to the directions of the strips II to be adsorbed by them.

[0128] Preferably, in order to ensure the material suction effect, the magnetic part II can be a powerful magnet.

[0129] Preferably, a detecting part IV 64 is correspondingly arranged on each material suction groove II 63 for detecting whether the strip II is adsorbed.

[0130] The material suction component II includes a mounting plate III 65. A material suction cylinder II 66 is arranged at the bottom of the mounting plate III 65, and the lower end of the piston rod of the material suction cylinder II 66 is connected to the material suction plate 62.

[0131] The top of the material suction cylinder II 66 is connected to the mounting plate III 65 through a spring I 67, which can automatically level the material suction plate 62 and ensure the material suction effect.

[0132] A retaining ring 68 connected to the mounting plate III 65 is arranged on the periphery of the material suction plate 62.

[0133] A slide carriage II 69 is arranged above the mounting plate III 65. A lifting cylinder VI 610 with a downward piston rod is installed on the slide carriage II 69, and a lifting cylinder VII 611 with an upward piston rod is installed on the mounting plate III 65, and the piston rods of the lifting cylinder VI 610 and the lifting cylinder VII 611 are connected.

[0134] Two transverse synchronous belts IV 612 are arranged in the frame IV 61. The synchronous belts IV 612 are correspondingly connected to the slide carriages II 69 of the two feeding components II one by one, and a synchronous wheel at one end of the synchronous belt IV 612 is drivingly connected to a motor IV 613.

[0135] A slide rail VII that cooperates with the bottom of the slide carriage II 69 is arranged at the top of the frame IV 61.

[0136] The process of loading the strip II is as follows: When the suction plate 62 moves above the feeding mechanism 8, the suction plate 62 moves downward under the action of the lifting cylinder VI 610 and the lifting cylinder VII 611. At this time, the suction cylinder II 66 continues to drive the suction plate 62 to move downward alone and extend into the feeding mechanism 8 to suck the strip II. After the suction is completed, the lifting cylinder VI 610 and the lifting cylinder VII 611 drive the suction plate 62 to rise. After the suction plate 62 rises in place, the carriage II 69 moves above the mold exchange mechanism 3 under the drive of the motor IV 613 and the synchronous belt IV 612. The lifting cylinder VI 610 and the lifting cylinder VII 611 then drive the suction plate 62 to move downward again. After moving in place, the suction cylinder II 66 drives the suction plate 62 to rise alone, and the strip II can fall into the mold 318 under the action of the retaining ring 68. At this time, the lifting cylinder VI 610 and the lifting cylinder VII 611 drive the suction plate 62 to rise, and use the synchronous belt IV 612 to move above the feeding mechanism 8 again, facilitating the next material taking operation.

[0137] The two loading components II are individually driven through the cooperation of two groups of independent synchronous belts IV 612 and motors IV 613, enabling the two loading components II to load materials alternately, avoiding interference.

[0138] The welded mesh needs to be unloaded from the mold 318. Therefore, a discharging station is provided in the front conveying mechanism 2, and the discharging mechanism 5 is correspondingly arranged at the discharging station.

[0139] The discharging mechanism 5 includes a discharging frame 51 and a suction magnetic plate 52 installed at the bottom of the discharging frame 51. The discharging frame 51 can move the mesh in the front conveying mechanism 2 to one side of the front conveying mechanism 2.

[0140] The discharging mechanism 5 further includes a discharging plate 53 installed below the discharging frame 51. The discharging plate 53 is connected to a pushing cylinder 54 installed above the discharging frame 51.

[0141] A detection plate 55 is arranged below the discharging frame 51. A spring II 56 is arranged between the detection plate 55 and the discharging frame 51. A detector V 57 is arranged above the detection plate 55.

[0142] Specifically, a connecting plate is installed on the discharging frame 51. The detection plate 55 is installed below the connecting plate through bolts. The bolts pass through the connecting plate and are fixed to the detection plate 55. The spring II 56 is sleeved on the bolts and is located between the detection plate 55 and the connecting plate. When the mesh is adsorbed, the detection plate 55 rises under the push of the mesh and compresses the spring II 56, and the detector V 57 can detect that the mesh has been adsorbed.

[0143] A carriage III 58 is arranged above the discharging frame 51. A lifting cylinder VIII 59 is installed on the carriage III 58. The piston rod of the lifting cylinder VIII 59 is connected to the discharging frame 51.

[0144] The unloading mechanism 5 includes a frame V510, which is arranged above the unloading station and extends towards one side of the front conveying mechanism 2.

[0145] A horizontal synchronous belt V511 is arranged on the frame V510. One end of the synchronous belt V511 is connected with a synchronous pulley, and the synchronous pulley is connected with a motor V512. The synchronous belt V511 is connected with the carriage III58.

[0146] A slide rail VIII which cooperates with the bottom of the carriage III58 is also arranged on the frame V510.

[0147] In order to be able to eject the mesh sheet in the mold 318 and facilitate adsorption on the suction magnetic plate 52, a top column 25 capable of moving up and down is arranged on the front conveying mechanism 2.

[0148] The top column 25 is installed on a top rack 26. The top rack 26 is located at the unloading station, and a top cylinder 27 is arranged at its bottom.

[0149] The process of unloading the mesh sheet is as follows: The mold rack 32 where the welded mesh sheet is located moves to the unloading station driven by the traction assembly. The top cylinder 27 drives the top column 25 to rise, and ejects the mesh sheet from the mold 318. The unloading rack 51 moves above the unloading station. The lifting cylinder VIII59 drives the suction magnetic plate 52 to descend. After adsorbing the mesh sheet, the lifting cylinder VIII59 drives the suction magnetic plate 52 to rise and reset. The carriage III58 moves to one side of the front conveying mechanism 2 driven by the synchronous belt V511. At this time, the lifting cylinder VIII59 drives the unloading rack 51 to descend. After descending in place, the pushing cylinder 54 drives the unloading plate 53 to descend, and the mesh sheet is separated from the suction magnetic plate 52 by the pushing of the unloading plate 53, completing the unloading.

[0150] The detection component can be selected but not limited to a proximity switch.

[0151] In this embodiment, there are also two feeding mechanisms 8, which are located on both sides of the mold exchanging mechanism 3 and opposite to the feeding mechanism 6.

[0152] The feeding mechanism 8 includes a material box 81 and a swing plate 82 which can swing and is installed in the material box 81. A number of protrusions I83 are arranged on the edge of the swing plate 82, and a number of protrusions II84 which are arranged in a staggered manner with the protrusions I83 are arranged on both sides of the swing plate 82. Through the swing of the swing plate 82 and the staggered arrangement of the protrusions I83 and the protrusions II84, the strip materials II can be placed neatly and evenly, facilitating the picking of the feeding mechanism 6.

[0153] The distribution direction of the protrusions I83 and the protrusions II84 and the swing direction of the swing plate 82 are both perpendicular to the axial direction of the strip material II.

[0154] A swing motor 85 is provided at the bottom of the feeding box 81. The swing motor 85 is drivingly connected to an eccentric wheel (not shown in the figure) through a belt pulley assembly, and the eccentric wheel is installed at the bottom of the swing plate 82. The swing motor 85 drives the eccentric wheel to rotate, and the eccentric wheel can drive the swing plate 82 to swing.

[0155] Both ends of the swing plate 82 extend from the end plates of the feeding box 81 and are supported on the rotating shafts outside the end plates. The arrangement of the rotating shafts can ensure the stability of the swing of the swing plate 82.

[0156] The welding mechanism 1 includes a welding machine 11. A plurality of upper electrode blocks 12 are arranged in a row above the welding interface of the welding machine 11, and each upper electrode block 12 is respectively connected to the power supply of the welding machine 11 through a copper busbar. The upper electrode blocks 12 are fixed on the welding machine 11 by upper cylinders 13; a lower electrode bar 14 corresponding to the upper electrode blocks 12 is arranged below the welding interface. The lower electrode bar 14 is connected to the power supply of the welding machine 11 through a copper busbar, and a plurality of lower cylinders 15 are arranged below the lower motor bar.

[0157] When the mold 318 placed with the frame and the strip II moves to the welding interface driven by the traction assembly, the single-row welding points are placed above the lower electrode bar 14. The lower electrode bar 14 and the upper electrode blocks 12 move relative to each other, and the welding of this row of welding points can be completed after being energized. Subsequently, each row of welding points is placed at this position in turn, and the welding of the entire mesh can be completed.

[0158] The present invention adopts an integrated structure and can complete the feeding, bending, butt welding of the frame, the feeding of the strip II, the assembly and welding of the strip II and the frame, and the unloading of the mesh through the precise cooperation of each mechanism, realizing the complete processing process of the mesh on the same equipment, effectively improving the processing efficiency of the mesh and ensuring the processing quality of the mesh.
