DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , a multi-station fully automatic engraving machine flipping device comprises a U-shaped frame 1, both end surfaces of the inner side of the U-shaped frame 1 are rotatably connected with discs 3, four groups of rollers 4 are rotatably connected between the two groups of discs 3, and the four groups of rollers 4 are distributed on the end surfaces of the discs 3 in a square structure, a second motor 7 is bolted on the outer end surface of the U-shaped frame 1, the output shaft of the second motor 7 passes through the U-shaped frame 1 and is fixedly connected to a group of discs 3, a support rod 8 is fixedly connected between the top and bottom of the two groups of discs 3, two groups of cylinders 9 are bolted at intervals on the end surfaces of the support rods 8, a fixing plate 10 is fixedly connected to the output shafts of the top two groups of cylinders 9, and a clamping plate 11 and a baffle 12 are fixedly connected to the bottom of the fixing plate 10, the height of the baffle 12 is greater than the height of the clamping plate 11 and does not exceed the height of the top roller 4, an L-shaped clamping plate 13 is fixedly connected to the output shafts of the bottom two groups of cylinders 9, and a limiting device 14 and a positioning device 15 are respectively arranged on the inner end surfaces of the U-shaped frame 1.

[0022] The limiting device 14 includes a fixed block 25 fixedly installed on the top and bottom of the inner side of the U-shaped frame 1, two groups of sliding rods 16 are arranged between the two groups of fixed blocks 25, a sliding seat 17 is slidably connected to the outer side of the sliding rod 16, and a rubber roller is rotatably connected to the end surface of the sliding seat 17, and a spring 18 is fixedly connected between the bottom of the sliding seat 17 and the top of the fixed block 25. The setting of the limiting device 14 prevents excessive wood transportation from increasing the turning radius and causing it to hit the edge of the carving table during turning.

[0023] The positioning device 15 includes an electric push rod 19 fixedly installed on the outside of the U-shaped frame 1. The output shaft of the electric push rod 19 passes through the U-shaped frame 1 and is fixedly connected to a cross bar 20. First abutment rollers are arranged at intervals on the end surface of the cross bar 20. A second abutment roller is arranged on the inner end surface of the U-shaped frame 1 away from the first abutment roller. The positioning device 15 is arranged to facilitate positioning of the wood, so as to vertically transmit it back to the engraving table for engraving.

[0024] A groove 22 is provided on the inner end surface of the U-shaped frame 1 away from the first abutment roller, and a mounting frame 23 is slidably connected inside the groove 22. The second abutment roller is arranged at the bottom of the mounting frame 23. An adjusting screw 24 is threadedly connected on the outer wall of the U-shaped frame 1, and the end of the adjusting screw 24 is rotatably connected to the end surface of the mounting frame 23. By adjusting the adjusting screw 24, the position of the wood when returning can be easily adjusted.

[0025] Both ends of the U-shaped frame 1 are provided with connecting blocks 2, and mounting holes are provided on the connecting blocks 2, so that the U-shaped frame 1 and the engraving table can be fixed conveniently through the connecting blocks 2.

[0026] A slot 21 is provided on the end surface of the L-shaped clamping plate 13 , and the baffle 12 is inserted into the slot 21 . Inserting the baffle 12 into the slot 21 increases the weighing force of the baffle 12 .

[0027] The L-shaped clamping plate 13 and the clamping plate 11 are both provided with rubber blocks on their opposite surfaces. The surfaces of the rubber blocks are provided with anti-skid convex patterns. The anti-skid convex patterns increase the friction force and are helpful for fixing the wooden board.

[0028] A rotating shaft 5 is rotatably connected between the two end surfaces inside the U-shaped frame 1, and rollers are arranged at intervals on the outside of the rotating shaft 5. A first motor 6 is bolted to the outside of the U-shaped frame 1, and the output shaft of the first motor 6 passes through the U-shaped frame 1 and is fixedly connected to the rotating shaft 5. The first motor 6 drives the rollers to rotate, thereby automatically returning the wood.

[0029] Working method: During operation, the user can connect the U-shaped frame 1 to the outer end of the engraving machine through the connecting block 2. When the wood board on the engraving machine needs to be turned over, the wood on the engraving machine is sent between the four sets of rollers 4 until it abuts against the rubber roller on the sliding seat 17, and the cylinder 9 is turned on. The top and bottom cylinders 9 respectively drive the clamping plate 11 and the L-shaped clamping plate 13 to clamp and fix the wood, and at this time, the baffle 12 is inserted into the slot 21 of the L-shaped clamping plate 13 to prevent the wood from slipping during the rotation process, and the second motor 7 is turned on. The second motor 7 drives the disc 3 to rotate, thereby driving the wood to flip over until the wood falls onto the roller of the rotating shaft 5, completing the flipping action. At this time, the wood presses down the rubber roller on the sliding seat 17, closes the cylinder 9, and the user can turn on the electric push rod 19. The electric push rod 19 brings the first abutting roller on the cross bar 20 to abut the wood to correct it and avoid tilting during the flipping process. After positioning, the user can turn on the first motor 6 to drive the rotating shaft 5 to rotate, so that the flipped wood is sent back to the engraving table for further processing.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
