The device packages aerated concrete blocks by setting a stacking machine, a supporting plate and a loading box. The packaging method is more stable than the binding type, the operation is relatively simple, and the transportation is convenient.

[0004] Although the packaging unit reduces the packaging difficulty to a certain extent, it still needs to manually install and fix the loading box, which has low packaging efficiency and high labor intensity, and is not convenient for packaging a large number of blocks.

Flexible straps (5) are inserted between adjacent pads (14). A support plate (15) for placing concrete blocks (13) is movably provided on the upper side of the pad (14).

2. The concrete block packaging machine according to claim 1, characterized in that, Two first springs (12) are symmetrically fixed on each slider (10), and the other end of each first spring (12) is connected and fixed to the inner wall of the corresponding slide groove (301).

3. A concrete block packaging machine according to claim 2, characterized in that, The guide grooves (201) are all U-shaped, and the U-shaped openings of the two guide grooves (201) located on the front or rear side are arranged opposite each other.

4. A concrete block packaging machine according to claim 1, characterized in that, The outer ends of the two front guide posts (9) extend to the front of the receiving plate (2) and are connected to a tightening assembly (7). The tightening assembly (7) includes a rotating mechanism that drives the guide posts (9) to rotate. The rotating mechanism includes two drive gears (702). The two drive gears (702) are respectively rotated and sleeved on the outer ends of the two front guide posts (9). The drive gears (702) are each meshed with a third rack (701). The third rack (701) is respectively fixedly installed on the outer side wall of the corresponding receiving plate (2). The outer ends of the two front guide posts (9) are each sleeved with a ratchet (703). The drive gears (702) are rotatably connected to a number of rotating posts (704) on the side of the ratchet (703). The rotating posts (704) are fixedly connected with pawls (705). The pawls (705) abut against the ratchet (703).

5. A concrete block packaging machine according to claim 4, characterized in that, A coil spring (706) is sleeved on the rotating column (704). The other end of the coil spring (706) is connected and fixed to the drive gear (702). Under the action of the coil spring (706), the drive gear (702) is successfully reset.

6. A concrete block packaging machine according to claim 1, characterized in that, The receiving plate (2) is constrained by and slidably connected to the mounting base (1), and can be used to package concrete blocks of different lengths by changing the distance between the guide grooves (201).

7. A method of using a concrete block packaging machine, implemented based on the concrete block packaging machine according to any one of claims 1-6, characterized in that, Includes the following steps: According to the length of the stacked concrete blocks, adjust the distance between the guide grooves (201). Specifically, loosen the two limiting rings (805) in sequence, adjust the distance between the two guide grooves (201) on one side and tighten the corresponding limiting rings (805), start the motor (11) to drive the guide column (9) to the middle of the guide groove (201), and then tighten the limiting ring (805) on the other side. The motor (11) drives the guide column (9) to return to the lower side of the guide groove (201). Place an appropriate number of straps (5) between adjacent pads (14) and place the stacked concrete blocks on the support plate (15) using external equipment. The start motor (11) drives the two drive plates (3) to rotate inward. Under the action of the slider (10) and the slide groove (301), the guide column (9) drives the pressure roller (6) to move along the guide groove (201). The pressure roller (6) then tightly attaches the binding strap (5) to the outside of the stacked concrete blocks. The start motor (11) reverses and drives the two drive plates (3) to reset, and the next packaging operation is carried out.
