[0002] As a widely used paving material for outdoor plazas, sidewalks, and other locations, the production efficiency and product diversity of paving stones are key concerns for manufacturers. Currently, paving stones are mostly produced using hydraulic molding machines, which press the brick blanks into shape through the impact of upper and lower molds. Frequent mold changes are required when producing paving stones of different colors and specifications. Traditional mold-changing methods are cumbersome and time-consuming, severely impacting the continuity and efficiency of the production line. Especially when small-batch, multi-variety production is needed, the time spent on mold changes becomes a bottleneck restricting capacity and flexibility. Therefore, developing a paving stone forming device that enables rapid mold changes to improve production flexibility and efficiency has become an urgent problem to be solved in this field.

[0021] In a preferred embodiment, the bottom surface of the top plate 101 is provided with an annular limiting mechanism 6, which is an annular cylindrical structure, and the bottom surface of the annular limiting mechanism 6 is provided with a support ring plate 601 extending inward. The rotating plate 5 is located within the annular limiting mechanism 6, and its bottom outer edge is supported by the supporting ring plate 601 to achieve vertical positioning.

[0022] In a preferred embodiment, a feed pipe 11 is provided on one side of the frame 1, and the feed pipe 11 extends directly above the conveying mechanism 2. A flow valve is provided on the feed pipe 11.

[0023] In a preferred embodiment, the frame 1 is provided with a support block 10, which is located below the lower template 3 and vertically aligned with the upper template 4; The support block 10 is used to support the lower template 3 that passes above it.

The top surface of the drying zone 12 is also equipped with a return air duct 14.

[0025] This utility model discloses a paving stone punching forming device that facilitates quick mold changes. Its operation is based on the core principles of "rotational mold selection, magnetic fixing, punching forming, and continuous operation," achieving efficient and flexible production of paving stones. The specific operating process and principle are as follows: The upper template 4 for pressing paving stones of different colors or specifications is pre-installed in each rectangular groove 9 of the rotating plate 5, and is fixed by adsorption between the first magnetic piece 401 on its top surface and the third magnetic piece 901 at the bottom of the groove, forming a "rotating mold library".

[0026] The conveying mechanism 2 operates continuously, driving the lower template 3 on it to pass through the frame 1 in sequence. When the empty lower template 3 runs to the bottom of the feed pipe 11, the flow valve opens, and a fixed amount of paving stone material is evenly spread into the mold cavity of the lower template 3.

[0027] According to the production order, the motor 7 at the top of the top plate 101 is started, driving the rotating plate 5 to rotate, and precisely rotating the pre-selected target upper template 4 to the working position (i.e., aligned vertically with the lower template 3 and support block 10 below).

[0028] The push rod 801 of the push cylinder 8 moves downward, and the connecting block 802 at its end approaches the target upper template 4. The second magnetic sheet 803 in the groove of the connecting block 802 generates a strong magnetic attraction with the metal connecting protrusion 403 on the top of the upper template 4, thereby firmly "grabbing" the upper template 4 onto the push rod 801.

[0029] The push cylinder 8 continues to drive the push rod 801 and the upper template 4 fixed thereto to move downwards as a whole. At this time, during the pause of the conveying mechanism 2, the bottom of the lower template 3 is rigidly supported by the support block 10. The printing protrusion 402 of the upper template 4 "collides" with the mold cavity of the lower template 3 filled with raw material, pressing the loose raw material into a paving stone brick blank with a dense structure and clear texture under great pressure.

[0030] After stamping is completed, the push cylinder 8 pulls the push rod 801 and the upper template 4 upward to reset. When the upper template 4 has completely returned to its rectangular groove 9, the upper template 4 is reliably released and re-fixed on the rotating plate 5, and the push rod 801 continues to rise to complete the demolding.

[0031] The conveyor mechanism 2 restarts, transporting the pressed brick blanks along with the lower mold 3 out of the frame 1 and towards the drying area 12; simultaneously, a new lower mold 3 containing raw materials is sent into the working position. If a product needs to be changed, the rotating plate 5 immediately rotates, switching the new upper mold 4 to the working position, repeating the above docking and pressing process to achieve rapid switching between different molds.

[0032] After being formed, the brick blanks enter the drying zone 12 under the drive of the conveying mechanism 2. Hot air is blown upward through the hot air branch pipes 131 on the hot air pipe 13 to perform preliminary curing and drying of the brick blanks, while the return air pipe 14 helps to distribute and recover heat evenly and improve energy efficiency.

[0033] This invention constructs a multi-station mold library using a rotating plate, and utilizes multi-level magnetic attraction to achieve rapid grasping, fixing and releasing of molds. Combined with precise punching and continuous material conveying, it ultimately achieves high efficiency, high flexibility and full automation in the production of paving stones.
