Description

Technical Field

[0001] The utility model relates to the technical field of color steel plate production lines, in particular to a single-plate stacking machine which can be adapted to a single / double-layer tile machine. Background Art

[0002] A veneer palletizer is a device that automatically stacks veneers of the same specifications into neat stacks. CN207876848 U discloses a veneer palletizer with a rational design. It uses a slider to divide the stacking chamber into two. Veeam entering the first stacking chamber first lands on the slider, maintaining its initial horizontal position. As the slider separates left and right, a clapboard strikes the veneer downward, causing it to fall at a faster rate, preventing it from floating around and causing an uneven stack. However, its structure is relatively complex and its cost is relatively high. CN 216510716 U discloses a fully automatic veneer palletizer, which can realize automated conveying during the stacking process of the board skins and facilitates the automated removal of the stacked board skins. It is easy to use, but its structure is relatively complex, its cost is relatively high, and it is mainly suitable for the stacking of wooden boards.

The receiving rack roller rotation drive cylinder is connected to the receiving rack roller through the receiving rack roller rotation transmission mechanism to drive the receiving rack roller to rotate and then put down the single board on the receiving rack roller;

[0009] The material receiving and conveying frame is arranged on the working surface and is located directly below the material receiving and conveying frame.

[0010] The veneer stacker of the utility model has a reasonable structural design. The height of the receiving frame roller arranged on the receiving frame can be adjusted by lifting the lifting frame to adapt to different board output heights. At the same time, the rotation of the receiving frame roller is driven by the cylinder and the receiving frame roller rotation transmission mechanism to realize the rotation of the receiving frame roller to release the veneer, and then the veneer is sent away by the receiving conveyor frame arranged below the receiving frame. The structure is relatively simple and the cost is low. It can be applied to veneer production lines with different specifications and heights according to needs. It has good applicability and good application prospects.

The rotating gear is fixed to the feeder via a rotating gear fixing shaft, and the rotating gear meshes with the rack. The feeder roller rotation transmission mechanism is rationally designed and relatively simple, effectively rotating the feeder rollers and releasing the veneers.

[0014] In the above-mentioned single board palletizer, the receiving rack roller is sleeved on the receiving rack roller shaft;

[0015] The roller shaft of the material receiving frame is fixed to the rotating gear through an L-shaped transfer rod.

[0016] In the single board palletizer as described above, there are two groups of rollers on the receiving rack, and the two groups of rollers are symmetrically arranged on both sides of the receiving rack.

[0017] In the veneer palletizer described above, the receiving and conveying frame is provided with a plurality of receiving and conveying frame rollers sequentially arranged along the conveying direction. The receiving and conveying frame rollers are driven by receiving and conveying frame roller driving motors to convey the veneers on the receiving and conveying frame rollers.

[0018] In the above-mentioned single-board palletizer, the lifting mechanism includes a lifting drive motor;

[0019] The lifting drive motor is installed on the top of the lifting frame, and the driving shaft of the lifting drive motor is coaxially connected with the horizontally arranged transmission shaft. A transmission gear I is fixed on the transmission shaft. The lifting screw is arranged vertically and is threadedly connected to the screw fixing sleeve. The screw fixing sleeve is fixed on the horizontal connecting rod of the base frame which is horizontally arranged and used to connect multiple base frames. A transmission gear II engaged with the transmission gear I is fixed on the top of the lifting screw.

[0020] In the single board palletizer as described above, the transmission gear I and the transmission gear II are bevel gears.

[0021] In the single board palletizer as described above, the material receiving rack is arranged horizontally.

[0022] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.
