Description

Technical Field

[0001] The utility model relates to the technical field of product conveying on a production line, in particular to a conveying device with a lifting platform. Background Art

[0002] The packaging, printing, and papermaking industries commonly use a descending-type paper collection system (referred to in the industry as a hanging basket system). Empty turnover pallets are placed on a lifting platform, which is then raised to the paper discharge surface of the equipment. The paper sheets are then neatly stacked onto the turnover pallets, which then automatically descend to adjust to the required height. The lifting platform then descends to the ground, where they are transferred by a manual operator and then a motorized forklift. During the turnover pallet changeover, the production line must stop discharging paper or transfer it to another stack for temporary storage. However, space is limited, and this can only last for less than 10 seconds. This requires staff to be on standby at all times and to quickly and skillfully prepare the forklift, pick up the goods, pull them away from the work area, place the pallets, calibrate their position, and raise the platform. Therefore, a device that can automatically and continuously collect paper is urgently needed. Utility Model Content

It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0014] The utility model discloses a conveying device with a lifting platform, comprising a base 1, a conveying mechanism 2, and a lifting mechanism 3. The base 1 is divided into three areas, wherein the lifting mechanism 3 is provided in the middle position. The conveying mechanism 2 is provided on both sides of the lifting mechanism 3. The lifting mechanism 3 includes a lifting frame 31 and a cylinder 32. A mounting frame is provided on the base 1, and mounting posts 33 are provided on both sides of the mounting frame. The ends of the mounting posts 33 are provided with connecting members 34 in a hinged manner. The ends of the connecting members 34 are connected to the lifting frame 31 through bearings. The mounting frame is provided with a cylinder 32, and the cylinder 32 is fixedly connected to the ends of the connecting members 34. In addition, in order to ensure that the lifting frame 31 can be connected to the conveying guide rail of the conveying mechanism 2 after being lowered, the height of the front and rear crossbeams of the lifting frame 31 is higher than the left and right crossbeams, thereby avoiding obstruction caused by the left and right crossbeams.

[0015] The conveying mechanism 2 includes a conveying trolley 21, a conveying track 22, a conveying motor 23, a chain 24 and a turnover pallet. The conveying motor 23 is arranged on the base 1 and is located between the conveying tracks 22. The conveying motor 23 is provided with a rotating wheel, and the rotating wheel is covered with a chain 24. The chain 24 is provided with a pushing claw. The pushing claw is a fixed block provided on the chain, which can push the conveying trolley to slide under the drive of the chain. Push claws are provided on the left and right sides of the chain, which can make the conveying trolley slide left and right. The conveying trolley 21 is connected to the conveying track 22 through the pulley at the bottom and can slide along the conveying track 22 with the chain 24. In addition, the conveying motor 23 adopts a forward and reverse motor, so that the conveying mechanism 2 can not only receive the finished products conveyed from the lifting mechanism 3, but also place turnover pallets on the conveying trolley 21. The turnover pallet full of finished products can be directly taken away by a forklift at any time, and the empty turnover pallet can be replaced to wait for the motor to convey it to the lifting mechanism. The empty conveying trolley 21 can also be transported back to the lifting mechanism 3 for the next round of finished product collection.

A movable plate 44 is sleeved on the limiting column 46. The movable plate 44 moves back and forth following the threaded column 45. The adjusting plate 43 is arranged above the conveying mechanism 2 through a connecting column and can move back and forth. When adjustment is required, the motor is started, and the motor rotates forward, thereby driving the gear to rotate, causing the threaded column 45 to rotate, driving the movable plate 44 to slide along the limit column 46, thereby pushing the adjustment plate 43 outside the mounting seat 42 forward. After the adjustment is completed, the motor rotates in the reverse direction, and the adjustment plate 43 moves backward to return to its original position. In order to further enhance the automation of the adjustment, touch switches 47 are provided at the front and rear of the movable plate 44 in the mounting seat 42. When the movable plate 44 moves forward and contacts the touch switches 47, the circuit is disconnected and the movable plate 44 stops moving forward.
