Detailed Description

As shown in fig. 1 to 9, a pouring assembly includes a pouring plate 20, a liquid outlet through hole 201 is provided on the pouring plate 20, a slurry outlet pipe 22 is provided in the liquid outlet through hole 201, the slurry outlet pipe 22 moves up and down in the liquid outlet through hole 201, and when the lower end of the slurry outlet pipe 22 extends out of the liquid outlet through hole 201, the slurry outlet pipe 22 is in a state of pouring out liquid. The slurry outlet pipe 22 is communicated with the slurry pump through the pump body. Since the liquid such as color paste or water has surface tension, the color paste adheres to the surface of the outlet. The pouring plate 20 is mostly in a planar state, and when the color paste is directly poured out from the liquid outlet through hole 201, more color paste is attached to the outlet of the liquid outlet through hole 201, which affects the amount of the poured color paste, thereby affecting the pouring accuracy of the pouring assembly. The pulp outlet pipe 22 arranged in the pulp outlet through hole 201 can effectively reduce the amount of the color paste attached to the pulp outlet of the pulp outlet pipe.

The thickness of the lower end surface of the pulp outlet pipe 22 is less than 1 millimeter. At the slurry outlet of the slurry outlet pipe 22, the inner diameter of the slurry outlet is the same, and the smaller the wall thickness is, the higher the precision is. The preferred wall thickness may be 0.5 mm and less. Or the grout outlet pipe 22 is a thin-walled pipe, and the thickness of the thin-walled pipe is less than 1 mm. Or the wall thickness of the lower end of the slurry outlet pipe 22 is gradually reduced from top to bottom. The thickness of the end surface, namely the wall thickness at the pulp outlet is less than 1 mm. A sealing mechanism 23 is arranged between the liquid outlet through hole 201 and the pulp outlet pipe 22. The sealing mechanism 23 may be a gasket.

The pulp outlet pipe 22 moves up and down in the pulp outlet through hole 201, indicating that the pulp outlet pipe 22 is extended downward by a downward force and retracted by an upward force. The specific structure can be as follows: the injection assembly further comprises a swing rod 24 rotatably arranged on the injection plate 20, an upper limit stop 220 and a lower limit stop 221 are arranged on the slurry outlet pipe 22, and the A end of the swing rod 24 is positioned between the upper limit stop 220 and the lower limit stop 221. When the end A of the swing rod 24 rotates downwards, the end A of the swing rod 24 pushes the lower limit stop block 221 to move downwards together with the pulp outlet pipe 22; when the swing lever 24 is rotated upward, the a end of the swing lever 24 pushes the upper limit stopper 220 to move upward together with the pulp outlet pipe 22. A power source is required to be provided to the rocking lever 24 to rotate the rocking lever. The power source for the oscillation may be a conventional mechanism. The oscillating lever 24 may be provided in a "7" shape or other shapes depending on the actual situation. The upper limit stopper 220 and the lower limit stopper 221 are located above the injection plate 20, i.e., on the side away from the contact surface of the injection plate 20 and the first valve element 26.

Or the pouring-out assembly also comprises a swing rod 24 which is rotatably arranged on the pouring-out plate 20, a lower limit stop 221 is arranged above the pouring-out plate 20 of the slurry outlet pipe 22, the end A of the swing rod is arranged above the lower limit stop 221, and a spring 25 is arranged between the slurry outlet pipe and the pouring-out plate 20. When the A end of the swing lever 24 is rotated downward, the A end of the swing lever pushes the lower limit stopper 221 to move downward together with the pulp outlet pipe 22. When the A end of the swing rod 24 rotates upwards, the resilience of the spring 25 provides an upward force for the pulp outlet pipe. The spring 25 can also be added to the previous embodiment, but in this case the spring 25 has a damping effect.

In order to prevent the color paste from drying out in the channel or the outlet, a dispensing assembly with a return function, i.e. a return dispensing assembly 2, can be used. The return flow injection assembly 2 further includes a first valve member 26, the first valve member 26 including at least one return flow passage 260, and relative movement between the first valve member 26 and the injection plate 20 transitioning the return flow injection assembly 2 between the injection position and the return flow position.
