[0033] A chalk ejection device also includes a reset component 400, which includes two U-shaped guide plates 410 connected to the support platform 100. The chalk forming mold includes an ejection unit 310 for ejecting chalk. The ejection unit 310 includes a sliding portion 311 protruding to both sides. The filling conveying chain 200 can drive the sliding portion 311 of the chalk forming mold 300 to enter the U-shaped guide plate 410 and slide and engage with the U-shaped guide plate 410. The U-shaped guide plate 410 can act on the sliding portion 311 to reset the ejection unit 310, thereby facilitating the subsequent filling of the slurry.

[0034] As one implementation, see Figure 2 and Figure 3 The reset assembly 400 also includes a vertically arranged first driving member 420, both ends of which are respectively connected to the support platform 100 and the U-shaped guide plate 410, the U-shaped guide plate 410 is arranged in a long strip shape, and the side of the U-shaped guide plate 410 away from the opening is slidably connected to the support platform 100. After the plurality of chalk forming molds enter the U-shaped guide plate 410, the first driving member 420 drives the U-shaped guide plate 410 to move relative to the support platform 100, so that the ejection unit 310 is reset, thereby facilitating the subsequent filling of the slurry.

[0035] It should be particularly noted that the first driving member 420 is a vertically arranged cylinder, hydraulic cylinder or electric push rod, which can push the U-shaped guide plate 410 to move vertically.

[0036] As another implementation, see Figure 4 and Figure 5The U-shaped guide plate 410 is arranged in an "S" shape, and the side of the U-shaped guide plate 410 away from the opening is fixedly connected to the support platform 100. The chalk forming mold can drive the sliding part 311 to move in the U-shaped guide plate 410. The "S"-shaped U-shaped guide plate 410 can pull the ejection unit 310 of the chalk forming mold to move relative to the support platform 100, so that the ejection unit 310 is reset, thereby facilitating the subsequent filling of the slurry.

[0037] In some embodiments, see Figure 6 The ejection unit 310 further includes a connecting column 312 and a chassis 313. A plurality of connecting columns 312 are slidably inserted into the grouting holes 321 of the chalk forming mold, and the chassis 313 is simultaneously connected to the plurality of connecting columns 312. After the slurry is formed in the grouting holes 321, the chassis 313 can simultaneously act on the plurality of connecting columns 312. The connecting columns 312 extend into the grouting holes 321, and the chalk in the grouting holes 321 can be pushed out to realize the discharging of the chalk.

[0038] In addition, after the ejection unit 310 has finished working, the U-shaped guide plate 410 acts on the chassis 313, and the chassis 313 drives the connecting column 312 to withdraw from the grouting hole 321, vacating the grouting hole 321 to prepare for the next grouting.

[0039] In some embodiments, please refer to Figure 6 The chalk forming mold 300 also includes a mold body 320, a grouting through hole 321 is opened in the mold body 320 and is arranged through the mold body 320, a plurality of grouting through holes 321 are arranged in an array, and a plurality of connecting columns 312 are arranged in a one-to-one correspondence with the plurality of grouting through holes 321. A plurality of chalks can be formed at one time in the plurality of grouting through holes 321 in one mold body 320, and the chassis 313 can simultaneously drive the plurality of connecting columns 312 to move, so as to realize the one-time feeding of a plurality of chalks, thereby realizing the batch production of chalks and greatly improving the production efficiency.

[0040] In some embodiments, see Figure 2 and Figure 4 The chalk ejection device also includes an ejection drive assembly 500, which includes an ejection bottom plate 510 and a second drive member 520. The two ends of the second drive member 520 are respectively connected to the ejection bottom plate 510 and the support platform 100. The ejection bottom plate 510 is arranged between the chalk forming mold 300 and the support platform 100. The ejection bottom plate 510 can act on multiple chalk ejection devices to drive the chassis 313 in the chalk ejection devices to move. The chassis 313 can act on multiple connecting columns 312 at the same time to push the chalk in the grouting through hole 321 out.

[0041] The second driving member 520 is specifically a vertically arranged cylinder, hydraulic cylinder or electric push rod, which can act on the ejection bottom plate 510 to realize automatic unloading of chalk.

[0042] As a further implementation, see Figure 7 The ejection drive assembly 500 and the reset assembly 400 are arranged along the filling conveying chain 200. The chalk forming mold after grouting passes through the ejection drive assembly 500 and the reset assembly 400 successively. The chalk forming mold is first automatically unloaded and then reset by driving the ejection unit 310.

[0043] In some embodiments, the filling conveyor chain 200 includes an upper conveyor chain 210 and a lower conveyor chain 220, and the upper conveyor chain 210 and the lower conveyor chain 220 form an annular conveyor chain, and a plurality of fixed plates are arranged on both sides of the annular conveyor chain, and the fixed plates can be fixedly connected to the chalk forming mold 300. The annular conveyor chain can drive the chalk forming mold 300 to circulate and rotate on a vertical plane to realize the automatic operation of the system. The annular conveyor chain can also drive the chalk forming mold 300 to reverse and reverse, so that the chalk can be easily removed under the action of gravity.

[0044] As a further implementation method, two annular conveyor chains are arranged at intervals, and the two sides of the chalk forming mold 300 are respectively connected to the two annular conveyor chains. The chalk forming mold 300 has two fulcrums, and the chalk forming mold 300 has better stability and smoother movement.

[0045] In some embodiments, see Figure 1 The supporting platform 100 includes a frame 110 and a rotating member 120. The frame 110 is a base placed on the ground. At least two rotating members 120 are connected to the frame 110. The rotating members 120 are specifically gears. The two rotating members 120 are arranged at a relative interval. The annular conveyor chain is sleeved on the two rotating members 120. The rotating member 120 is connected to the servo motor through a rotating shaft. The servo motor can drive the rotating member 120 to rotate, thereby driving the movement of the chalk forming mold 300 to complete the automatic operation of the chalk production line.

[0046] Workflow: First, start the servo motor to make the filling conveyor chain 200 automatically feed and rotate. Then, the chalk forming mold 300 located on the upper conveyor chain 210 passes through the filling equipment in turn, and the filling equipment fills the grouting through hole 321 with slurry. Next, the filling conveyor chain 200 drives the chalk forming mold 300 to flip upside down, and the chalk forming mold 300 moves to the lower conveyor chain 220. Then, the ejection bottom of the ejection drive assembly 500 acts on the chassis 313 of the chalk forming mold 300 to promote automatic unloading of chalk, and the filling conveyor chain 200 drives the chalk forming mold 300 to be inserted into the U-shaped guide plate 410. The U-shaped guide plate 410 can act on the sliding part 311 of the ejection unit 310 to reset the ejection unit 310, thereby facilitating the subsequent filling of slurry.
