[0020] like Figure 1-5 As shown, the present invention proposes a sand particle shaping machine for producing manufactured sand, including a shaping chamber 1 and two guide plates 3 that are symmetrically fixedly connected to the inner wall of the shaping chamber 1. The upper end of the shaping chamber 1 is open and the opening is conical. Two shaping rollers 4 are rotatably installed on the inner wall of the shaping chamber 1 and located below the guide plates 3. A drive assembly for driving the shaping rollers 4 is provided on the back of the shaping chamber 1. An arc-shaped guide frame 6 covering the forming roller 4 is fixedly connected to the lower surface of the guide plate 3, and a processing component 7 located below is provided in the forming chamber 1.

[0021] In this invention, the processing component 7 can perform a more detailed secondary shaping process on the manufactured sand after it has been shaped by the shaping roller 4, thereby improving the shaping effect of the manufactured sand.

[0022] It should be noted that the drive assembly includes a support cover 8 fixedly connected to the back of the shaping chamber 1. The rear ends of the two shaping rollers 4 pass through the shaping chamber 1 and extend into the support cover 8. The ends of the two shaping rollers 4 located inside the support cover 8 are fixedly connected to meshing gears 10. A rotary motor 9 is fixedly installed on the back of the support cover 8. The output shaft of the rotary motor 9 passes through the support cover 8 and is fixed to the rear end of the right shaping roller 4. After the rotary motor 9 is started, it drives the right shaping roller 4 to rotate. The two meshing gears 10 can drive the left shaping roller 4 to rotate synchronously in the opposite direction to perform the initial shaping treatment on the manufactured sand guided by the guide plate 3.

[0023] In an optional embodiment, the processing component 7 includes a shaping cylinder 71 fixedly connected to the inner wall of the shaping chamber 1 and located below the guide frame 6. A drive motor 713 is fixedly installed on one side of the shaping chamber 1, and the output shaft of the drive motor 713 is fixedly connected to a drive shaft 75 that extends through and into the inner side of the shaping cylinder 71. A plurality of annularly distributed stirring rods 77 are fixedly connected to the outer surface of the drive shaft 75, and a plurality of grinding balls 76 are placed inside the shaping cylinder 71. The inner wall of the shaping chamber 1 slides upwards. A vibrating plate 74 is movably connected to the shaping cylinder 71 below it, and a screen 79 is fixedly installed on the vibrating plate 74. A drive shaft 711 is rotatably connected to the inner wall of the shaping chamber 1, with one end penetrating through and extending to the outside of it, and located below the vibrating plate 74. Two cams 712 are fixedly installed on the drive shaft 711. A guide port is opened at the center of the lower surface of the shaping cylinder 71, and a filter screen 78 is installed in the guide port. A valve located below the filter screen 78 is also installed at the guide port, but is not shown in the figure.

[0024] In this embodiment, the rotating stirring rod 77, in conjunction with the grinding balls 76 inside the shaping cylinder 71, can turn over and grind the manufactured sand inside the shaping cylinder 71, so that the manufactured sand has a better shaping effect after the secondary shaping process, and there is no need to put it back into the shaping process afterward, thereby improving the processing efficiency of the manufactured sand.

[0025] It should be noted that the inner wall of the shaping chamber 1 is provided with an elastic support for the vibrating plate 74. The drive shaft 711 and the drive shaft 75 are provided with a transmission assembly 710 at the outer end of the shaping chamber 1. The transmission assembly consists of two pulleys and a transmission belt. The two pulleys are fixedly connected to the drive shaft 75 and the drive shaft 711 at the outer end of the shaping chamber 1, respectively. The transmission belt is sleeved on the two pulleys, so that the rotating drive shaft 75 can drive the drive shaft 711 to rotate synchronously through the two pulleys and the transmission belt. The transmission belt is a synchronous toothed belt, and the contact point between the pulley and the transmission belt is provided with a toothed groove that matches the toothed belt. The grinding balls 76 are zirconia balls, and the pore size of the filter screen 78 is smaller than that of the grinding balls 76 but larger than that of the manufactured sand particles, while the pore size of the sieve 79 is smaller than that of the manufactured sand particles.

[0026] Both the vibrating plate 74 and the screen 79 are arc-shaped, and the vibrating plate 74 is inclined with the left side higher than the right side, so that after the vibrating plate 74 receives the discharged manufactured sand, it can guide and screen the manufactured sand at the same time. The size of the left cam 712 is larger than that of the right cam 712, so that the rotating left cam 712 can still repeatedly abut against the high position of the vibrating plate 74.

[0027] In addition, the shaping cylinder 71 is a cone shape that is wide in the middle and narrow at both ends, so that the manufactured sand in the secondary shaping process inside the shaping cylinder 71 can always accumulate towards the middle of the shaping cylinder 71, and a guide hopper is connected to the center of its upper surface. The guide hopper can guide the manufactured sand after shaping by the shaping roller 4 into the shaping cylinder 71. A discharge port 5 is opened on one side of the shaping chamber 1 at the low position of the shaking plate 74. The manufactured sand after being guided and screened by the shaking plate 74 is discharged through the discharge port 5.

[0028] In an optional embodiment, two guide grooves are provided on both the left and right side walls of the inner cavity of the shaping chamber 1. The elastic support includes a guide block 714 slidably connected in the guide groove. A vertical rod 716 passing through the guide block 714 is fixedly connected in the guide groove. A reset spring 715 is fixedly connected between the guide block 714 and the inner side of the guide groove.

[0029] In this embodiment, the guide block 714 in the guide groove, together with the reset spring 715, provides elastic support for the shaking plate 74, so that the shaking plate 74 can reciprocate along the vertical horizontal plane during the process of being squeezed and pressed by the cam 712.

[0030] In an optional embodiment, the processing component 7 further includes a slag guide plate 72 that is slidably connected inside the shaping chamber 1 and located below the drive shaft 711. A support spring 73 is fixedly connected between the lower surface of the slag guide plate 72 and the inner bottom wall of the shaping chamber 1. The slag guide plate 72 is inclined with the right side higher than the left side, and a slag discharge port 2 located at the lower position of the slag guide plate 72 is opened on the other side of the shaping chamber 1.

[0031] In this embodiment, since the slag guide plate 72 is elastically supported by the support spring 73, the rotating cam 712 can also abut against the slag guide plate 72, so that the slag guide plate 72 can reciprocate and shake, and then cooperate with the slag discharge port 2 to discharge the impurities screened by the screen 79 into the shaping chamber 1.

[0032] The working principle in the above embodiments is as follows: After the manufactured sand is fed into the shaping bin 1 from above, the rotating motor 9 and the drive motor 713 can be started respectively. After the rotating motor 9 drives the right shaping roller 4 to rotate, the two meshing gears 10 can drive the left shaping roller 4 to rotate synchronously in the opposite direction to perform the initial shaping process on the manufactured sand guided by the guide plate 3 to the two shaping rollers 4. After the initial shaping process, the manufactured sand is guided into the shaping cylinder 71 through the guide frame 6 and the guide hopper on the upper surface of the shaping cylinder 71. The started drive motor 713 drives the stirring rod 77 on the drive shaft 75 to rotate, which in turn works with the grinding balls 76 in the shaping cylinder 71 to tumble and grind the manufactured sand in the shaping cylinder 71. This allows the manufactured sand to undergo a more detailed secondary shaping process in the shaping cylinder 71, resulting in a better shaping effect. Since the rotating drive shaft 75 can drive the drive shaft 711 to rotate synchronously through two pulleys and a transmission belt, the drive shaft 711 can drive the vibration plate 74 and the slag guide plate 72 to vibrate back and forth along the vertical horizontal plane when the drive shaft 711 repeatedly squeezes and abuts against the vibration plate 74 and the slag guide plate 72. Therefore, after the second shaping, the valve on the feed port on the lower surface of the shaping cylinder 71 can be opened, and the filter screen 78 on the feed port can intercept the grinding balls 76. The manufactured sand can be discharged from the shaping cylinder 71 after being filtered by the filter screen 78. The discharged manufactured sand falls onto the screen 79 of the shaking plate 74. After the screen 79 screens out impurities, it can be discharged along the discharge port 5. The screened impurities fall onto the guide plate 72 and are discharged along the vibrating guide plate 72 and the discharge port 2.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
