Description

Technical Field

[0001] The invention relates to the technical field of wooden pallet transportation and turnover, in particular to a turnover device for nailing a wooden pallet. Background Art

[0002] As we all know, wooden pallets are made of natural wood and are primarily used in logistics as tools and platforms for the collection, stacking, handling, and transportation of goods and products. They are crucial logistics equipment for transforming static cargo into dynamic cargo, serving as a horizontal platform for unit loads of goods and products. During the production of wooden pallets, nails are driven into the wood using a nail gun. The nailing process is typically a tedious one, with multiple nails applied to each pallet. The pallet often needs to be nailed on both or multiple sides, requiring it to be flipped over.

[0003] When using the existing flipping device for nailing wooden pallets, the wooden pallet is generally placed on the nailing device, and then the wooden pallet is nailed by the nailing device. When the nailing is completed, the wooden pallet is taken out and flipped. During use, after the nailing is completed, the wooden pallet needs to be taken out separately and flipped before the nailing operation can be carried out again, which makes the nailing operation more cumbersome, reduces the nailing efficiency of the wooden pallet, and is inconvenient for users to use. Summary of the Invention

[0004] The present invention provides a flipping device for nailing a wooden pallet to solve the problem that in the use of existing vegetable cultivation racks, due to the limited planting land resources, most of the vegetables are stacked up in multiple layers during the planting process. During the planting process, since the planting height of each layer of vegetables is fixed, when the bottom layer vegetables grow faster and higher, they are easily blocked by the top layer planting rack, thereby hindering the growth of the bottom layer vegetables during the cultivation process.

[0005] The top end of the lifting gear is fixed with a lifting mechanism, and the lifting gear is installed in the lifting mechanism, and the lifting gear is installed at the bottom end of the lifting mechanism.

[0010] Preferably, a limiting frame is installed on one side of the first lifting frame, a double-headed motor is installed on the top of the limiting frame, and transmission rods are installed at both ends of the double-headed motor.

[0011] Preferably, a second lifting frame is installed at one end of the first lifting frame, and a second gear plate is installed at the bottom end of the second lifting frame.

[0012] Preferably, a mounting slot is provided at the top end of the positioning clamping plate, a rotating wheel is installed inside the mounting slot, and a mounting shaft is inserted into the inside of the rotating wheel.

[0013] Preferably, the flip mechanism includes a first flip motor installed on one side of the finished product transport mechanism, a first flip shaft is installed at one end of the first flip motor, and a first flip plate is connected to one side of the first flip shaft.

[0014] Preferably, a second flip motor is installed on one side of the first flip motor, a second flip shaft is installed on one end of the second flip motor, and a second flip plate is connected to one end of the second flip shaft.

[0015] Beneficial effects:

[0016] 1. When the present invention performs the nailing operation on the pallet body, first, each plate on the wooden pallet body is placed at the corresponding position on the top of the mounting frame body, and the driving motor installed in the positioning frame is turned on to rotate the motor driving shaft. The rotation of the motor driving shaft drives the left and right screw rods to rotate synchronously. Under the rotation of the left and right screw rods, the corresponding two sets of screw nuts installed on the outer walls of the left and right screw rods are driven to move closer to each other. The movement of the screw nuts drives the moving slider and the positioning splint to move closer to each plate on the wooden pallet body. The two sets of positioning plywood will position the boards on the wooden pallet body to avoid displacement of the boards during the nailing operation. When the positioning plywood moves, it will slide along the inside of the limiting slide. The movement of the positioning plywood is limited by the limiting slide, which increases the movement stability of the positioning plywood. At the same time, the three vertical groups of boards on the wooden pallet body can be positioned by opening the positioning electric cylinders in the corresponding positions, so that the electric cylinder shaft drives the clamping plates closer to the boards. The three vertical groups of boards are clamped and fixed by the corresponding clamping plates, making the wooden pallet body more stable during the nailing process and less likely to deviate.

[0017] 2. When the nailed wooden pallet body is transported, the present invention first turns on the driving motor and the electric cylinder shaft to release the plates clamped in the corresponding positions by the positioning splint and the clamping plate. At this time, the double-headed motor is turned on to rotate the transmission rod and the first bevel gear. When the first bevel gear rotates, it drives the second bevel gear meshed on one side to rotate, thereby rotating the driven rod and the transmission wheel. Under the rotation of the transmission wheel, the first tooth plate meshed on one side and the first lifting frame are driven to move upward. At the same time, the second tooth plate will also synchronously drive the second lifting frame to move upward, so that the first lifting frame and the second lifting frame move upward at the same time until they pass through the transportation trough and lift the wooden pallet body to the positioning splint. The height of the height is reached, at this time, the transmission motor inside the installation chamber is turned on, so that the transmission shaft drives the transmission gear to rotate, and the rotation of the transmission gear will drive the driven gear meshed at the top to rotate synchronously. Under the rotation of the driven gear, the driven shaft and the rotating roller will rotate, thereby driving the transmission belt meshed on the outer wall of the rotating roller to move, and the rotation of the transmission belt will drive multiple groups of driven rollers on the inner wall of the transmission belt to rotate. Under the rotation of the driven roller, the connecting shaft and the conveying wheel will be driven to rotate, thereby driving the wooden pallet body to move to the left at the top of the first lifting frame and the second lifting frame through the multiple groups of conveying wheels, until the wooden pallet body is driven to the top of the flipping mechanism.

[0018] 3. When the present invention flips the wooden pallet body, when the wooden pallet body is transported to the middle of the top of the first flip plate and the second flip shaft through the finished product transportation mechanism, the first flip motor can be turned on first, so that the first flip shaft drives the first flip plate to rotate upward. At this time, the first flip plate will lift the wooden pallet body on the top of the first lifting frame and the second lifting frame, and then flip it toward the second flip plate. At the same time, by turning on the second flip motor, the second flip shaft drives the second flip plate to rotate in the direction of the first flip plate, and the wooden pallet body is flipped to one end of the second flip plate through the first flip plate. Then, by turning on the second flip motor again, the second flip plate is returned to its position, thereby completing the flipping operation of the wooden pallet body.

When the present invention is used, when it is necessary to nail the wooden pallet body 3, first, each plate on the wooden pallet body 3 is placed at the corresponding position at the top of the mounting frame main body 1, and the driving motor 603 installed in the positioning frame 601 is turned on to make the motor drive shaft 604 rotate. The rotation of the motor drive shaft 604 will drive the left and right screw rods 605 to rotate synchronously. Under the rotation of the right-hand screw rod 605, the corresponding two groups of screw nuts 606 installed on the outer walls of the left and right screw rods 605 will be driven to move closer to each other. Through the movement of the screw nuts 606, the moving slider 607 and the positioning splint 608 will be driven to move closer to each plate on the wooden pallet body 3. The plates on the wooden pallet body 3 are positioned by the corresponding two groups of positioning splints 608 to avoid displacement of the plates during the nailing operation. When the positioning splint 608 moves, it will slide along the inside of the limiting slide 4. The movement of the positioning splint 608 is limited by the limiting slide 4, which increases the movement stability of the positioning splint 608. At the same time, the three vertical groups of plates on the wooden pallet body 3 can be moved by turning on the positioning motors at the corresponding positions. Cylinder 609 causes the electric cylinder shaft 610 to drive the clamping plate 611 to approach the plate, and the three vertical groups of plates are clamped and fixed by the corresponding clamping plates 611, so that the wooden pallet body 3 is more stable during the nailing process and is not easy to deviate. When the nailing of the wooden pallet body 3 is completed, the driving motor 603 and the electric cylinder shaft 610 are first turned on to make the positioning clamping plate 608 and the clamping plate 611 release the plates clamped in the corresponding positions. At this time, the double-headed motor 714 is turned on to make the transmission rod 715 and the first bevel gear 716 rotate. When the first bevel gear 716 rotates, it will drive the second bevel gear 717 engaged on one side to rotate, thereby making the driven rod 718 and the transmission wheel 719 rotate. Under the rotation action of the transmission wheel 719,The first tooth plate 720 and the first lifting frame 701 engaged on one side will be driven to move upward, and the second tooth plate 721 will also synchronously drive the second lifting frame 725 to move upward, so that the first lifting frame 701 and the second lifting frame 725 move upward at the same time, until they pass through the transport chute 5 and lift the wooden pallet body 3 to the height of the positioning clamping plate 608. At this time, the transmission motor 703 inside the installation compartment 702 is turned on, so that the transmission shaft 704 drives the transmission gear 705 to rotate, and the transmission gear 705 is rotated. The rotation of the driven gear 706 at the top will drive the synchronous rotation of the driven gear 706. Under the rotation of the driven gear 706, the driven shaft 707 and the rotating roller 708 will rotate, thereby driving the transmission belt 709 meshed with the outer wall of the rotating roller 708 to move. The rotation of the transmission belt 709 will drive the multiple sets of driven rollers 710 on the inner wall of the transmission belt 709 to rotate. Under the rotation of the driven roller 710, the connecting shaft 711 and the conveying wheel 712 will be driven to rotate, thereby The wheel 712 drives the wooden pallet body 3 to move to the left at the top of the first lifting frame 701 and the second lifting frame 725 until the wooden pallet body 3 is driven to the top of the turning mechanism 8. When the wooden pallet body 3 is transported to the middle of the top of the first turning plate 803 and the second turning shaft 805 by the finished product transport mechanism 7, the first turning motor 801 can be turned on first, so that the first turning shaft 802 drives the first turning plate 803 to rotate upward. At this time, the first turning plate 803 will lift the wooden pallet body 3 at the top of the first lifting frame 701 and the second lifting frame 725, and then turn it toward the second turning plate 806. At the same time, by turning on the second turning motor 804, the second turning shaft 805 drives the second turning plate 806 to rotate toward the first turning plate 803, and the wooden pallet body 3 is turned to one end of the second turning plate 806 through the first turning plate 803. Then, by turning on the second turning motor 804 again, the second turning plate 806 returns to its original position, thereby completing the turning operation of the wooden pallet body 3.

[0041] When nailing the wooden pallet body 3, the present invention positions each board on the wooden pallet body 3 through the positioning mechanism 6 to avoid the deviation of the nailing position caused by the displacement of the board during the nailing operation. The positioning mechanism 6 includes a positioning frame 601 installed inside the mounting frame body 1. The top of the positioning frame 601 is provided with a mounting groove 602. A driving motor 603 is installed inside the mounting groove 602. One end of the driving motor 603 is installed with a motor driving shaft 604. One end of the motor driving shaft 604 is installed with a left and right screw rod 605. The left and right screw rod 605 is provided with a right and left screw rod 605. The outer wall is sleeved with a screw nut 606, and the outer wall of the screw nut 606 is installed with a moving slider 607, and the top of the moving slider 607 is installed with a positioning clamping plate 608. The top of the mounting frame body 1 is installed with a positioning electric cylinder 609, and one end of the positioning electric cylinder 609 is installed with an electric cylinder shaft 610, and one end of the electric cylinder shaft 610 is installed with a clamping plate 611. When it is necessary to nail the wooden pallet body 3, first, each plate on the wooden pallet body 3 is placed at the corresponding position on the top of the mounting frame body 1, and the driving motor 6 installed in the positioning frame 601 is turned on. 03, so that the motor drive shaft 604 rotates, and the rotation of the motor drive shaft 604 drives the left and right screw rods 605 to rotate synchronously. Under the rotation of the left and right screw rods 605, the corresponding two sets of screw nuts 606 installed on the outer walls of the left and right screw rods 605 are driven to move closer to each other. Through the movement of the screw nuts 606, the moving slider 607 and the positioning splint 608 are driven to move closer to each plate on the wooden pallet body 3. The plates on the wooden pallet body 3 are positioned by the corresponding two sets of positioning splints 608 to avoid nailing during the nailing operation. During the process, the board is displaced. When the positioning splint 608 moves, it will slide along the inside of the limiting slide 4. The movement of the positioning splint 608 is limited by the limiting slide 4, which increases the movement stability of the positioning splint 608. At the same time, the three vertical groups of boards on the wooden pallet body 3 can be opened by the positioning electric cylinder 609 at the corresponding position, so that the electric cylinder shaft 610 drives the clamping plate 611 to approach the board, and the three vertical groups of boards are clamped and fixed by the corresponding clamping plates 611, so that the wooden pallet body 3 is more stable during the nailing process and is not prone to displacement.

[0042] After the nailing of the wooden pallet body 3 is completed, the wooden pallet body 3 is automatically moved and transported by the finished product transport mechanism 7. The finished product transport mechanism 7 includes a driven gear 706 meshing with the top of the transmission gear 705, and a driven shaft 707 is installed at one end of the driven gear 706. A rotating roller 708 is installed at the end of the driven shaft 707 away from the driven gear 706. The outer wall of the rotating roller 708 is meshed with a transmission belt 709, and the inner wall of the transmission belt 709 is meshed with a driven roller 710. A connecting shaft 711 is installed at one end of the driven roller 710, and a conveying wheel 712 is installed at one end of the connecting shaft 711. A limiting frame 713 is installed on one side of the first lifting frame 701, and a limiting frame 713 is installed on the top of the limiting frame Double-headed motor 714, both ends of double-headed motor 714 are equipped with transmission rod 715, one end of the first lifting frame 701 is equipped with a second lifting frame 725, the bottom end of the second lifting frame 725 is equipped with a second tooth plate 721, the top of the positioning splint 608 is provided with a mounting slot 722, the interior of the mounting slot 722 is equipped with a rotating wheel 723, and the interior of the rotating wheel 723 is plugged with a mounting shaft 724. When the nailing of the wooden pallet body 3 is completed, the driving motor 603 and the electric cylinder shaft 610 are first turned on to release the plates clamped in the corresponding positions of the positioning splint 608 and the clamping plate 611. At this time, the double-headed motor 714 is turned on to rotate the transmission rod 715 and the first bevel gear 716. When the first bevel gear 716 rotates, it will drive the second bevel gear 717 engaged on one side to rotate, thereby causing the driven rod 718 and the transmission wheel 719 to rotate. Under the rotation of the transmission wheel 719, the first tooth plate 720 engaged on one side and the first lifting frame 701 will be driven to move upward. At the same time, the second tooth plate 721 will also synchronously drive the second lifting frame 725 to move upward, so that the first lifting frame 701 and the second lifting frame 725 move upward at the same time until they pass through the transport chute 5 and lift the wooden pallet body 3 to the height of the positioning clamping plate 608. At this time, by opening the transmission motor 703 inside the installation compartment 702, the transmission shaft 704 drives the transmission gear 705 to rotate, and through the transmission gear 7 05's rotation will drive the top meshed driven gear 706 to rotate synchronously, and the rotation of the driven gear 706 will cause the driven shaft 707 and the rotating roller 708 to rotate, thereby driving the transmission belt 709 meshed on the outer wall of the rotating roller 708 to move, and the rotation of the transmission belt 709 will drive the multiple sets of driven rollers 710 on the inner wall of the transmission belt 709 to rotate, and the rotation of the driven roller 710 will drive the connecting shaft 711 and the conveying wheel 712 to rotate, thereby driving the wooden pallet body 3 to move to the left at the top of the first lifting frame 701 and the second lifting frame 725 through the multiple sets of conveying wheels 712 until the wooden pallet body 3 is driven to the top of the flipping mechanism 8.

[0043] During use of this solution, when the wooden pallet body 3 needs to be flipped after nailing is completed, the wooden pallet body 3 is flipped by the flipping mechanism 8. The flipping mechanism 8 includes a first flipping motor 801 installed on one side of the finished product transportation mechanism 7, and a first flip shaft 802 is installed at one end of the first flip motor 801. A first flip plate 803 is connected to one side of the first flip shaft 802. A second flip motor 804 is installed at one side of the first flip motor 801, and a second flip shaft 805 is installed at one end of the second flip motor 804. One end of the second flip shaft 805 is connected to the second flip plate 806. When the wooden pallet body 3 is transported to the top of the first flip plate 803 and the second flip shaft 805 by the finished product transportation mechanism 7, When the wooden pallet body 3 is turned on, the first turning motor 801 can be turned on first, so that the first turning shaft 802 drives the first turning plate 803 to rotate upward. At this time, the first turning plate 803 will lift the wooden pallet body 3 at the top of the first lifting frame 701 and the second lifting frame 725, and then turn it toward the second turning plate 806. At the same time, the second turning motor 804 can be turned on, so that the second turning shaft 805 drives the second turning plate 806 to rotate in the direction of the first turning plate 803, and the wooden pallet body 3 is turned over to one end of the second turning plate 806 through the first turning plate 803. Then, the second turning motor 804 can be turned on again to make the second turning plate 806 return to its original position, thereby completing the turning operation of the wooden pallet body 3.

[0044] It should be noted that the rotation angle of the first flip plate 803 is greater than the flip angle of the second flip plate 806 . When the wooden pallet body 3 flips from the first flip plate 803 to the second flip plate 806 , the wooden pallet body 3 will fall onto the second flip plate 806 .

[0045] The working principle of the present invention is as follows: when it is necessary to carry out nailing operation on the wooden pallet body 3, first, each plate on the wooden pallet body 3 is placed on the corresponding position of the top of the mounting frame body 1, and the driving motor 603 installed in the positioning frame 601 is turned on to make the motor drive shaft 604 rotate. The rotation of the motor drive shaft 604 will drive the left and right screw rods 605 to rotate synchronously. Under the rotation action of the left and right screw rods 605, the corresponding two groups of screw nuts 606 installed on the outer walls of the left and right screw rods 605 will be driven to move closer to each other. Through the movement of the screw nuts 606, the moving slider 607 and the positioning splint 608 will be driven to move closer to each plate on the wooden pallet body 3. The positioning clamp 608 positions the planks on the wooden pallet body 3 to prevent the planks from being displaced during the nailing operation. When the positioning clamp 608 moves, it slides along the inside of the limiting slide 4, and the movement of the positioning clamp 608 is limited by the limiting slide 4, which increases the movement stability of the positioning clamp 608. At the same time, the three vertical groups of planks on the wooden pallet body 3 can be moved closer to the planks by opening the positioning electric cylinder 609 at the corresponding position, so that the electric cylinder shaft 610 drives the clamping plate 611 to move closer to the planks, and the three vertical groups of planks are clamped and fixed by the corresponding clamping plates 611, so that the wooden pallet body 3 is more stable during the nailing process and is not prone to displacement. When the nailing of the wooden pallet body 3 is completed, the driving electric cylinder 609 is turned on first. The machine 603 and the electric cylinder shaft 610 cause the positioning clamping plate 608 and the clamping plate 611 to release the plates clamped in the corresponding positions. At this time, the double-headed motor 714 is turned on to rotate the transmission rod 715 and the first bevel gear 716. When the first bevel gear 716 rotates, it will drive the second bevel gear 717 engaged on one side to rotate, thereby causing the driven rod 718 and the transmission wheel 719 to rotate. Under the rotation action of the transmission wheel 719, the first tooth plate 720 engaged on one side and the first lifting frame 701 will be driven to move upward. At the same time, the second tooth plate 721 will also synchronously drive the second lifting frame 725 to move upward, so that the first lifting frame 701 and the second lifting frame 725 move upward at the same time until they pass through the transport chute 5. The wooden pallet body 3 is lifted up to the height of the positioning splint 608. At this time, the transmission motor 703 inside the installation compartment 702 is opened, so that the transmission shaft 704 drives the transmission gear 705 to rotate. The rotation of the transmission gear 705 will drive the driven gear 706 meshed at the top to rotate synchronously. Under the rotation of the driven gear 706, the driven shaft 707 and the rotating roller 708 will rotate, thereby driving the transmission belt 709 meshed on the outer wall of the rotating roller 708 to move. The rotation of the transmission belt 709 will drive the multiple groups of driven rollers 710 on the inner wall of the transmission belt 709 to rotate. Under the rotation of the driven roller 710, the connecting shaft 711 and the conveying wheel 712 will be driven to rotate.Thus, the wooden pallet body 3 is driven to move to the left at the top of the first lifting frame 701 and the second lifting frame 725 by multiple sets of conveying wheels 712 until the wooden pallet body 3 is driven to the top of the turning mechanism 8. When the wooden pallet body 3 is transported to the middle of the top of the first turning plate 803 and the second turning shaft 805 by the finished product transport mechanism 7, the first turning motor 801 can be turned on first, so that the first turning shaft 802 drives the first turning plate 803 to rotate upward. At this time, the first turning plate 803 will lift the wooden pallet body 3 at the top of the first lifting frame 701 and the second lifting frame 725, and then turn it toward the second turning plate 806. At the same time, by turning on the second turning motor 804, the second turning shaft 805 drives the second turning plate 806 to rotate toward the first turning plate 803, and the wooden pallet body 3 is turned to one end of the second turning plate 806 by the first turning plate 803. Then, by turning on the second turning motor 804 again, the second turning plate 806 returns to its original position, thereby completing the turning operation of the wooden pallet body 3.
