Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, and particularly relates to an automatic cardboard conveying mechanism. Background Art

[0002] The processing of cartons usually goes through steps such as cardboard cutting, indentation, box gluing, and printing. After a certain process of the cardboard is completed, it needs to be stacked and conveyed to the next process for processing. The currently adopted conveying mechanism includes a first conveyor rack and a second conveyor rack located below one end of the first conveyor rack. There is a receiving plate for receiving the cardboard between the first conveyor rack and the second conveyor rack. The cardboard flies out from the first conveyor rack and falls onto the receiving plate. When the cardboard on the receiving plate is stacked to a certain number, the receiving plate moves down to be flush with the second conveyor belt on the second conveyor rack, so that the stacked cardboard is moved to the next process along with the second conveyor belt.

[0003] However, the above-mentioned conveying mechanism still has some deficiencies: after the cardboard on the receiving plate is stacked according to the specified quantity, the first conveyor belt stops working, so that the cardboard no longer flies out from the first conveyor belt. Wait until the receiving plate places the cardboard stacked on it on the second conveyor belt and is conveyed away by the second conveyor belt. After the receiving plate moves up in place, the first conveyor belt continues to work and starts a new round of stacking and sorting of the cardboard, and the conveying efficiency is relatively low. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an automatic cardboard conveying mechanism aiming at the above defects, which can continuously carry out the stacking and conveying work of the cardboard and improve the conveying efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an automatic cardboard conveying mechanism, including a first conveyor rack and a second conveyor rack located below the rear end of the first conveyor rack. There is a baffle at the rear end of the first conveyor rack. There is a receiving part between the first conveyor rack and the second conveyor rack. The receiving part includes a first receiving plate arranged on the baffle and a second receiving plate arranged between the first conveyor belt and the second conveyor belt. One side of the first receiving plate is provided with a first driving mechanism for driving it to move horizontally. A second driving mechanism for driving it to move vertically is arranged below the second receiving plate. The first receiving plate is located above the second receiving plate.

[0006] Explanation: The first conveyor rack and the second conveyor rack are respectively provided with a first conveyor belt and a second conveyor belt. The second conveyor belt includes a plurality of belts arranged at intervals. When the upper side of the second receiving plate is flush with the upper side of the second conveyor belt, the cardboard on the second receiving plate will be conveyed forward under the drive of the second conveyor belt.

[0007] Working principle of this solution: During the processing of cardboard, it is necessary to stack and divide the cardboard processed in the previous process and transfer it to the next process, that is, stack the cardboard on the first conveyor belt and then transport it to the second conveyor belt for subsequent processing of the cardboard. When the cardboard on the first conveyor belt moves to its rear end, it will fly outwards due to inertia. After the cardboard flies outwards for a certain distance, it is blocked by a baffle. The cardboard then falls down onto the first receiving plate and is stacked. After stacking a certain number of cardboard, the second receiving plate is driven by a second driving mechanism to move upwards until the upper side of the second receiving plate contacts the lower side of the first receiving plate. Then, the first receiving plate is driven by a first driving mechanism to retract in a direction away from the first conveyor frame until all the cardboard on the first receiving plate falls onto the second receiving plate; when all the cardboard on the first receiving plate has fallen onto the second receiving plate, the second receiving plate is driven by the second driving mechanism to move downwards by a certain distance, so that the cardboard on the first conveyor belt continues to fall above the cardboard stack. When the cardboard is stacked to the specified number, the second receiving plate moves downwards, and the first receiving plate extends in a direction towards the first conveyor frame. The cardboard that continues to fall falls onto the first receiving plate. The second receiving plate moves down until its upper side is flush with the second conveyor belt. The cardboard stack is transported away by the second conveyor belt. Then, the second receiving plate is driven by the second driving mechanism to move upwards, repeating the above steps, and the cardboard can be continuously stacked and transported for subsequent processing.

[0008] Compared with the prior art, the beneficial effect of this solution is that: through the cooperation of the first receiving plate and the second receiving plate, the cardboard can be continuously stacked and transported, and there is no need to stop the first conveyor belt during the process of the first receiving plate collecting a certain number of cardboard stacks and transporting the cardboard stack away through the second conveyor belt, improving the transportation efficiency.

[0009] As a preferred embodiment of the present utility model, the first receiving plate includes a plurality of first connecting blocks arranged at intervals, the second receiving plate includes a plurality of second connecting blocks arranged at intervals, and the first connecting blocks and the second connecting blocks are arranged in a staggered manner.

[0010] Beneficial effect of this solution: When transferring the cardboard stack on the first receiving plate to the second receiving plate, the second receiving plate is driven by the second driving mechanism to move upwards until each of the plurality of first connecting blocks is respectively caught in the gaps between adjacent two second connecting blocks and the lower side of the second receiving plate is flush with the upper side of the first receiving plate. Then, the first receiving plate is driven by the first driving mechanism to move away from below the second receiving plate, and the stacked cardboard can be smoothly transferred from the first receiving plate to the second receiving plate.

[0011] As a preferred embodiment of the present utility model, a mounting plate perpendicular to the baffle is provided on the side of the baffle away from the first conveyor frame. The first receiving plate and the first driving mechanism are both located on the mounting plate, and a through hole for the first receiving plate to pass through is provided on the baffle.

[0012] Beneficial effects of this solution: The mounting plate for mounting the first receiving plate and the first driving mechanism is arranged on the side of the baffle away from the first conveyor rack, that is, the mounting plate is located above the second conveyor rack, without occupying extra space and having a reasonable structure.

[0013] As a preferred embodiment of the present utility model, a limiting plate is arranged vertically on the side of the second receiving plate away from the second conveyor rack.

[0014] Beneficial effects of this solution: The lower part of the stack of cardboard placed on the second receiving plate is limited by the limiting plate, avoiding the offset of the cardboard at the bottom when there are too many stacked cardboard, which affects the neatness of the cardboard stack.

[0015] As a preferred embodiment of the present utility model, sliding blocks are respectively arranged on both sides of the second receiving plate along its length direction, and sliding grooves for slidingly cooperating with the sliding blocks are respectively arranged vertically on the inner sides of the two brackets at the rear end of the first conveyor rack.

[0016] Beneficial effects of this solution: By the sliding cooperation of the sliding blocks arranged on both sides of the second receiving plate and the sliding grooves arranged on the inner sides of the brackets, not only can the movement of the first receiving plate be guided, but also the situation that the first receiving plate tilts to one side due to too much cardboard placed on the first receiving plate can be avoided.

[0017] As a preferred embodiment of the present utility model, the second driving mechanism includes two cylinders arranged on the lower side of the second receiving plate, and a mounting seat is arranged at the bottom of each cylinder, and grooves for snap-fitting with the mounting seats are respectively arranged on the inner sides of the two brackets at the rear end of the first conveyor rack.

[0018] Beneficial effects of this solution: By snap-fitting the mounting seat arranged at the bottom of the cylinder with the groove arranged on the inner side of the bracket, the second driving mechanism is connected to the first conveyor rack, so that the second driving mechanism and the second receiving plate are more stable during the vertical movement process.
