For the above problems, there may be technical means to solve in the prior art, but the present case wants to provide an alternative or replacement technical solution. UTILITY MODEL CONTENT

[0005] It needs to be explained that, in the above, through the operation of the belt conveyor inside the concave-shaped transport platform, the mold on it is driven to move horizontally stably, through the operation of the vertical and horizontal screw module on the concave-shaped sleeve block, the vertical and horizontal moving plate on the vertical and horizontal screw module is driven to move, through the vertical and horizontal moving plate, the two pairs of lifting hydraulic push rods on it are driven, through the two pairs of lifting hydraulic push rods, the pushing lifting plate on it is driven, so that the pushing lifting plate moves vertically and horizontally in the horizontal direction and stably vertically, through the operation of the horizontal rotary drive machine on the pushing lifting plate, the horizontal rotary bevel gear set is driven to operate, the horizontal rotary bevel gear set drives the horizontal rotary disc on it, so that the horizontal rotary disc rotates stably on the pushing lifting plate, through the horizontal rotary disc, the angle adjusting spraying assembly on it is driven to rotate stably, through the extrusion pump, the raw materials inside the raw material box are drained to the inside of the flexible pipe, through the flexible pipe, the raw materials are drained to the inside of the angle adjusting spraying assembly.

[0006] Preferably, the angle adjusting assembly comprises: an L-shaped feeding pipe, a Y-shaped drainage pipe, a pair of L-shaped drainage pipes, a pair of telescopic limiting rings, a pair of telescopic sleeve rings, a pair of telescopic ring magnets, a pair of telescopic ring electromagnets, a T-shaped rotating rod, a pair of rotating discs, a pair of rotating limiting rings, two pairs of circular arc rotating sliders, two pairs of rotating circular arc shafts, two pairs of angle adjusting ring magnets, two pairs of angle adjusting ring electromagnets and two pairs of sleeve springs.

[0007] The Y-shaped drainage tube is inserted into the horizontal rotating disk, the L-shaped feeding tube is inserted into the pushing lifting plate, and the L-shaped feeding tube is mounted on the Y-shaped drainage tube through a sealed bearing. The flexible tube is connected to the L-shaped feeding tube. A pair of L-shaped drainage tubes are respectively movably inserted into the inner side of a pair of Y-shaped drainage tubes. A pair of telescopic limiting rings are installed on the Y-shaped drainage tubes. A pair of telescopic sleeve springs are respectively mounted on a pair of L-shaped drainage tubes. A pair of telescopic ring magnets are respectively installed on a pair of telescopic sleeve rings.
