[0032] Example: Figures 1-5 As shown, this embodiment provides a molding sand shaping machine, including a frame 1, shaping wheels, a driver 4, and shaping vertical chains 5. Several shaping wheels are rotatably mounted on the frame 1, distributed directly above the sand feeding belt along its conveying direction. The lower end of the shaping wheels moves in the opposite direction to the feeding direction of the sand feeding belt. The shaping wheels are used to break up clumps of sand on the sand feeding belt. The driver 4 is mounted on the frame 1 and drives the shaping wheels to rotate. Several shaping vertical chains 5 are provided, with their upper ends connected to the frame 1 and their lower ends naturally hanging down onto the sand feeding belt. The shaping vertical chains 5 are used to break up clumps of sand on the sand feeding belt.

[0033] Through the above setup, the efficiency and degree of dispersing clumps of sand on the feeding belt are improved by the cooperation of multiple shaping wheels and shaping vertical chains 5. The structure is simple, the performance is stable, the failure rate is low, and it can significantly change the performance of molding sand, improve the compaction rate and yield of molding sand, and greatly improve the consistency of casting product dimensions.

[0034] In this embodiment, the shaping wheel in a molding sand shaping machine is a cross-shaped shaping wheel with two cross-shaped shaping wheels. The angles of the two cross-shaped shaping wheels are tangent to each other, resulting in a significant shaping effect. It breaks up clumps of sand more thoroughly and is more efficient. Specifically, the shaping wheel includes a wheel body 31 and several blade-shaped gates 32 evenly distributed around the outer circumference of the wheel body 31. The blade-shaped gates 32 are fixed to the wheel body 31 by screws or other fasteners, and break up clumps of sand on the sand conveyor belt through the blade-shaped gates 32.

[0035] In this embodiment of a molding sand shaping machine, there are two shaping wheels, namely a first shaping wheel 2 and a second shaping wheel 3. The two shaping wheels work together to break up clumps of sand on the feeding belt, balancing breaking efficiency and cost control.

[0036] In a molding sand shaping machine according to this embodiment, the driver 4 includes a motor 41, a first transmission assembly 42, and a second transmission assembly 43. The motor 41 is mounted on the upper part of the frame 1; the first transmission assembly 42 is used to connect the motor shaft of the motor 41 and the rotating shaft of the first shaping wheel 2, and the motor 41 is used to drive the first shaping wheel 2 to rotate through the first transmission assembly 42; the second transmission assembly 43 is used to connect the rotating shafts of the two shaping wheels so that the second shaping wheel 3 rotates with the first shaping wheel 2.

[0037] In this embodiment of a molding sand forming machine, the first transmission assembly 42 and the second transmission assembly 43 are located on opposite sides of the frame 1, respectively. The structural layout is compact and regular.

[0038] In this embodiment of a molding sand forming machine, the first transmission component 42 is a sprocket and chain transmission component or a belt pulley transmission component, and the second transmission component 43 is a sprocket and chain transmission component or a belt pulley transmission component. This configuration results in a simple structure and stable transmission.

[0039] In this embodiment of a molding sand forming machine, protective covers 6 are provided on the exterior of both the first transmission assembly 42 and the second transmission assembly 43. This provides protection for the workers.

[0040] In this embodiment of a molding sand forming machine, a mounting base 8 is fixedly installed on the upper part of the frame 1. A waist-shaped sliding groove 81 is formed on the mounting base 8. The base of the motor 41 is slidably mounted on the waist-shaped sliding groove 81 and fixed with fasteners. This facilitates adjustment of the position of the motor 41, thereby facilitating adjustment of the tension between the motor 41 and the first transmission assembly 42.

[0041] In this embodiment of a molding sand forming machine, two sets of arc-shaped adjusting frames 13 are fixedly installed on the frame 1. Arc-shaped adjusting holes 131 are provided on the two sets of arc-shaped adjusting frames 13. One end of a protective cover 6 disposed on the outer periphery of the first transmission component 42 is adjustablely mounted on one set of arc-shaped adjusting frames 13 and locked by fasteners passing through the corresponding arc-shaped adjusting holes 131. The other end of the protective cover 6 on the outer periphery of the first transmission component 42 is adjustablely mounted on the other set of arc-shaped adjusting frames 13 and locked by fasteners passing through the corresponding arc-shaped adjusting holes 131. This configuration, using two sets of arc-shaped adjusting frames 13 to install the protective cover 6, allows for adjustment of the installation angle of the protective cover 6, thereby adapting to the adjustment of the motor 41 position. The structure is simple and has a wide range of applications.

[0042] In this embodiment of a molding sand shaping machine, the two ends of the frame 1 are a sand inlet 11 and a sand outlet 12, respectively. The shaping wheel is located inside the frame 1, and the shaping vertical chain 5 is located at the sand outlet 12 of the frame 1.

[0043] In this embodiment of a molding sand shaping machine, the shaping vertical chains 5 are arranged in several groups, and these groups of shaping vertical chains 5 are distributed above the sand feeding belt along the feeding direction of the sand feeding belt. This arrangement provides a good effect in breaking up clumps of sand on the sand feeding belt.

[0044] In this embodiment of a molding sand shaping machine, an inverted U-shaped cover 7 is fixedly installed at the sand outlet 12 of the frame 1, and the shaping vertical chain 5 is located in the inverted U-shaped cover 7. The shaping vertical chain 5 is confined in the inverted U-shaped cover 7 to prevent the shaping vertical chain 5 from swinging outside the sand feeding belt and affecting the dispersing efficiency.

[0045] In this embodiment of a molding sand shaping machine, a horizontal suspension rod 71 is fixedly installed on the frame 1, and the shaping vertical chain 5 is hung on the horizontal suspension rod 71. The structure is simple and the cost is low.

[0046] The working principle is as follows:

[0047] 1. The shaping machine is installed on the sand feeding belt and works simultaneously with the sand feeding belt.

[0048] 2. The rotation direction of the blade-shaped shaping wheel is opposite to the movement direction of the sand feeding belt.

[0049] 3. When the molding sand on the sand conveyor belt moves forward, the two counter-rotating blade-shaped shaping wheels of the molding sand shaping machine will push the clumps of sand in the opposite direction and break them into a soft state.

[0050] 4. To prevent the molding sand from piling up too high on the sand conveyor belt or to prevent the appearance of loose sand clumps, install one or more heavy-duty vertical chains at the outlet of the molding machine to break up the loose sand clumps a second time.
