[0033] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0034] An embodiment of a flipping device is proposed in the present utility model, which includes:

[0035] A support frame 100;

[0036] In some embodiments of the present application, the support frame 100 includes:

[0037] Two sub-frame bodies 110 are provided, arranged oppositely, and an accommodating space is formed between the two sub-frame bodies 110.

[0038] The support frame 100 is mainly used for supporting and fixing.

[0039] A flipping module 200 is arranged in the accommodating space, and at least one end is rotatably connected to the sub-frame body 110. It includes:

[0040] A flipping base 210;

[0041] In some embodiments of the present application, the flipping base 210 includes: a flipping cover body 211, which is horizontally arranged;

[0042] and side members 212 connected to both sides of the flip cover body 211. There are 2 side members 212, which are symmetrically connected to the flip cover body 211.

[0043] The side member 212 is a side plate, which is arranged perpendicular to the flip cover body 211 and is disposed at the middle position of the flip cover body 211.

[0044] The flip base 210 further includes an auxiliary plate group, which is provided with 2 groups and is symmetrically arranged on both sides of the flip cover body 211.

[0045] Each auxiliary plate group includes 2 auxiliary mounting plates 213, and the 2 auxiliary mounting plates 213 are symmetrically connected to the side member 212 on the same side as it.

[0046] The pressing module 220 is movably connected to the flip base 210;

[0047] The lifting module 230 is movably connected to the flip base 210, is disposed below the pressing module 220, and a feeding space 300 is formed between the lifting member 231 and the pressing member 221;

[0048] The feeding space 300 has a feeding end and a discharging end. The material plate enters the feeding space 300 from the feeding end and then is conveyed out of the feeding space 300 from the discharging end.

[0049] The lifting module 230 can cooperate with the pressing module 220 to press and position the material plate in the feeding space 300.

[0050] During operation, the pressing module 220 can move downward relative to the flip base 210;

[0051] The lifting module 230 is oppositely arranged with the pressing module 220, and it can move upward relative to the pressing module 220;

[0052] When the material plate is not pressed and positioned, there is a certain distance between the two and they form the feeding space 300.

[0053] When the material enters the feeding space 300 between the two, the pressing module can move downward, and the lifting module 230 moves upward to press and position the material plate in the feeding space.

[0054] Position the material plate through the relative movement mode of the pressing module 220 and the lifting module 230. The relative movement of the two can ensure that the material plate between the two can be firmly clamped and positioned, with firm positioning, good positioning stability and high positioning accuracy;

[0055] The material conveying module 400 is assembled on the flipping base 210 and is arranged through the feeding space 300 along the material conveying direction for conveying the material plate into the feeding space 300;

[0056] The material conveying module 400 is mainly used to convey the material plate into the feeding space 300 to facilitate the cooperation of the lifting module 230 and the pressing module 220 to press and position the material plate.

[0057] Since the material conveying module 400 is arranged through the feeding space 300, it can ensure that the external material plate enters the feeding space 300 under its conveying. After the locking operation is completed, it can continue the conveying operation to convey the material plate after locking to the next process, ensuring the continuity of the production operation and improving the production operation efficiency.

[0058] The flipping power module 500 is assembled on the support frame 100 and is used to drive the flipping module 200 with the positioned material plate to flip. The flipping power module 500 provides the rotation power for the flipping module 200 to drive the flipping module 200 to flip relative to the support frame 100.

[0059] After the material plate enters the feeding space 300, the lifting module 230 and the pressing module 220 move in cooperation to press and fix the material plate from above and pull from below. After positioning and fixing, locking is required. At this time, the entire flipping module 200 can be driven by the flipping power module 500 to flip 180 degrees for the locking operation.

[0060] After the locking operation is completed, the flipping module 200 can be driven by the flipping drive module to reverse flip 180 degrees to reset. During the entire flipping process, the pressing module 220 and the lifting module 230 always keep pressing and fixing the material plate, thus ensuring the position accuracy of the flipped material plate and further ensuring the position accuracy when it is conveyed to the next processing equipment at the next position.

[0061] In some embodiments of the present application, the pressing module 220 includes:

[0062] A pressing component 221;

[0063] A pressing power member 222 is assembled on the flipping cover 211 and is connected to the pressing component 221 for driving the pressing component 221 to move up and down.

[0064] The pressing component 221 is a pressing plate group, and the pressing plate group includes a connecting plate and a pressing plate arranged up and down.

[0065] To ensure the pressing and positioning effect on the material plate, the bottom surface of the pressing plate is set as a plane.

[0066] The pressing power component 222 is a pressing cylinder, which is assembled on the flipping cover 211. It has a pressing cylinder rod, and the end of the pressing cylinder rod is connected to the connecting plate to achieve the connection and fixation with the pressing component 221.

[0067] In some embodiments of the present application, to realize the guiding of the pressing component 221 during its up and down movement and ensure its accurate up and down movement for pressing operations, a guiding assembly is provided between the flipping cover 211 and the pressing component 221. The guiding assembly includes a plurality of guiding rods 240.

[0073] The material driving component 410 is a material driving motor, and the material transmission component 420 is a material transmission shaft, which is horizontally arranged and is rotatably connected to two auxiliary mounting plates 213 located at opposite positions of the flipping base 210 at both ends respectively.

[0074] To achieve its rotational connection with the auxiliary mounting plate 213, bearings can be installed on the auxiliary mounting plate 213.

[0075] The material driving component 410 rotates, transmits power to the material transmission component 420, and the material transmission component 420 drives the sprocket and chain transmission mechanism to operate for material plate conveying.

[0076] In some embodiments of the present application, it further includes: a mounting seat 440, which is assembled on the material transmission component 420;

[0077] The mounting seat 440 is assembled at the middle position of the material transmission component 420 and is rotatably connected to the material transmission component 420 through bearings to avoid interfering with the rotation of the material transmission component 420.

[0085] The driving sprocket 431 is arranged at the end of the material transmission member 420;

[0086] The driven sprocket set 432 has two sets, which are respectively arranged at both ends of the track body 450;

[0087] The redirecting sprocket set is assembled on the mounting base / flipping base, arranged above the driving sprocket 431, and symmetrically arranged on both sides of the driving sprocket 431;

[0088] The chain 435 is wound around the driving sprocket 431, the redirecting sprocket set and the driven sprocket set 432.

[0089] Specifically, two driving sprockets 431 are provided, which are respectively arranged at both ends of the material transmission member 420;

[0090] The driven sprocket set 432 has two sets, which are respectively arranged on the two track bodies 450;

[0091] The driven sprocket set 432 at least includes: the first driven sprocket 4321 and the second driven sprocket 4322 arranged at both ends of the track body 450.

[0092] The driven sprocket set 432 further includes a guiding sprocket 4323, which is arranged between the first driven sprocket 4321 and the second driven sprocket 4322.

[0093] The redirecting sprocket set includes redirecting sprockets 433 symmetrically arranged on both sides above the driving sprocket 431.

[0094] There are two chains 434, which are respectively wound around the corresponding driving sprocket 431, redirecting sprocket 433 and driven sprocket set 432 on the corresponding side.

[0095] The rotation of the material transmission member 420 drives the rotation of the driving sprocket 431 above it, and then drives the rotation of the redirecting sprocket set and the driven sprocket set 432. The chain 434 above it moves to convey the material plate.

[0096] To achieve uniform support for the conveyed material plate, a supporting track 435 is provided on the track body. The conveying section of the chain 434 in the upper part is arranged above the supporting track 435, ensuring the stability of the conveying.

[0097] In some embodiments of the present application, the lifting module 230 includes:

[0098] A lifting member 231, arranged below the pressing member 221;

[0099] At least one lifting power member 232, assembled on the side member 212 and connected to the lifting member 231, for driving the lifting member 231 to move up and down.

[0100] The lifting member 231 is a lifting plate group, including a supporting plate 2311, and the supporting plate 2311 is horizontally arranged between two side members 212;

[0101] And a lifting operation plate 2312 assembled on the supporting plate 2311. The width of the lifting operation plate 2312 is narrow, and its width is less than the distance between two relatively arranged chains 434.

[0102] When arranged, there is a first distance between the supporting plate 2311 and the chain 434, and a second distance between the lifting operation plate 2312 and the chain. The second distance is less than the first distance and the lifting operation plate is higher than the supporting plate 2311.

[0103] When the lifting module 230 pulls up the material plate, the material plate can be lifted from the material conveying module 400 by the upward movement of the lifting operation plate 2312, so that the material plate is separated from the material conveying module 400. At the same time, the pressing module 220 moves down to cooperate with the lifting module 230 to position the material plate.

[0104] After completing the locking operation, the lifting module 230 can be moved down to drive the lifting operation plate to move down to release the limit on the material plate, so that the material plate automatically falls onto the driven sprocket set 432 to continue the conveying operation.

[0105] To screw the material plate between the pressing module 220 and the lifting module 230, avoidance holes are provided on both the lifting operation plate 2312 and the supporting plate 2311.

[0106] The lifting power member 232 is a lifting cylinder, which is connected to the lifting member 231 through a vertically arranged connecting member 233.

[0107] The connecting member 233 is a vertical connecting plate, which is connected to the piston rod of the lifting cylinder.

[0108] By the telescopic movement of the piston rod of the lifting power member 232, the lifting member 231 can be pulled upward to clamp and position the material plate.

[0109] In some embodiments of the present application, it further includes: a track width adjusting device, including:

[0110] An adjusting power member 610, assembled on the flipping base 210;

[0111] The adjusting power member 610 is an adjusting motor, which is assembled on the auxiliary mounting plate.

[0112] A first track width adjusting mechanism 620, arranged at the opposite end to the material conveying module 400, including:

[0113] A first lead screw component 621, one end of which is connected to the adjusting power member 610, and the other end is rotatably connected to the flipping base 210;

[0114] An assembly seat 622, installed on the lead screw component, with a first nut portion 623 formed above it and cooperating with the lead screw component, which is connected to the track body 450 connected to the mounting seat 440;

[0115] The track body 450 extends from the mounting seat 440 to the position of the assembly seat 622 and is respectively connected to the mounting seat 440 and the assembly seat 622.

[0116] The first nut portion 623 is a first nut sleeve, fixed on the assembly seat 622.

[0117] The first lead screw component 621 passes through the assembly group and the first nut sleeve and is in threaded cooperation with the first nut sleeve.

[0118] When the adjusting power member 610 rotates, it drives the first lead screw component 621 to rotate. Since the first lead screw component 621 is rotatably connected to the flipping base 210 and cannot move linearly, its rotation is converted into the linear movement of the first nut portion 623. By driving the assembly seat 622 and the track body 450 to move closer to or away from the track body 450 assembled on the flipping base 210 through the first nut portion 623, the position of the track body 450 can be adjusted.

[0125] The second nut portion 632 is a second nut sleeve, integrally formed with the mounting seat 440.

[0126] The second lead screw component 631 passes through the second nut sleeve and is threadedly connected to the second nut sleeve.

[0127] A synchronous pulley mechanism, connected between the first lead screw component 621 and the second lead screw component 631.

[0128] The synchronous pulley mechanism includes two synchronous pulleys 633, respectively connected to the ends of the first lead screw component 621 and the second lead screw component 631, and a synchronous belt is wound around the two synchronous pulleys 633.

[0129] A synchronous guide pulley can also be provided between the two synchronous pulleys 633.

[0130] When the first lead screw component 621 rotates, it drives the synchronous pulley 633 above it to rotate. The power is transmitted to the synchronous pulley 633 on the second lead screw component 631 through the synchronous belt. The second lead screw component 631 is driven to rotate by the synchronous pulley 633, driving the second nut portion 632 to move linearly, and further enabling the two ends of the track body 450 to move synchronously, achieving synchronous adjustment of the position of the track body 450.
