The material check of check charging tray 54 are arranged in the matrix, and after distributing device 10 cloth each material check in the check charging tray 54, charging tray positioning seat 13 carries check charging tray 54 in discharge apparatus's the space of unloading, and telescopic cylinder 52 drives electromagnet and moves down and laminates with the last side of check skeleton this moment, and control system control electromagnet circular telegram excitation adsorbs the check skeleton on electromagnet's the side of going up promptly the adsorption plane. Because the turnover door is also made of magnetic materials, when the exciting current is larger, the adsorption force can be generated on the turnover door and the turnover door is kept in a closed state. The electromagnetic chuck is driven by the telescopic cylinder 52 to move upwards, the material tray positioning seat 13 is retracted, then the telescopic cylinder 52 extends out and drives the grid framework to move downwards until the grid framework is close to the forming tray 55 on the discharging device, at the moment, the controller controls the exciting current to be reduced, the magnetic force of the electromagnetic chuck is reduced, the turnover door is released when the electromagnetic chuck keeps adsorbing the grid material tray 54, and the turnover door is opened so that the pigment in the grid material tray 54 can fall into the forming tray 55. The turnover door adopts magnetism to inhale the control and opens and close the even application of force that can realize each turnover door, and the local of turnover door takes place to warp because the gravity of particulate matter when avoiding setting up integral turnover door to can avoid cloth and unload the influence.
In order to ensure that the coloring materials arranged in a set pattern in the grid tray 54 do not deform the pattern due to the time difference of the falling of the various coloring materials when falling into the forming tray 55, the turnover doors of at least two material grids of the grid framework rotate synchronously when opening, so that the synchronism of the coloring materials in the grid tray 54 when falling into the forming tray 55 can be improved.
The particle printer further comprises a control system, the control system is connected with the conveying device, the printing mechanism, the feeding valve 30 and the blanking valve 44, color programming is firstly carried out on a picture to be printed when particle printing is carried out, solid particles are selected according to edited color element points in a one-to-one correspondence mode and printed electronic signals are formed when printing is carried out, each solid particle/each group of solid particles is regarded as one printed color element point, different colors and different textures are presented by the combination of different solid particles, and after cloth distribution is completed, the solid particles can be mutually combined and fixed through a bonding agent, so that the picture is formed.
Specifically, for the material distributing step, the main material cartridges 22 are filled with the particles of different colors, and the print heads 41 corresponding to the moving material cartridges 42 correspond to the particles of one color respectively. During material distribution, the printing heads 41 and the grid tray 54 relatively move in a stepping manner along the column direction, at each stepping position, the two printing heads 41 move in the row direction perpendicular to the column direction, and discharge the loaded corresponding color particles to all the corresponding color material grids in the corresponding row of the grid tray 54, and in the process, the printing heads 41 complete the material distribution to all the corresponding color material grids in the corresponding row of the grid tray 54 in a one-way traversing manner. Of course, at the first step position, there may be a blank space in the row of grids after the row of grids is printed, because there are only two print heads 41 corresponding to the row of grids. The printing head 41 and the grid tray 54 continue to move relatively in a unidirectional stepping mode, and step by one row of material grids at a time, and in the unidirectional stepping process, each row of printing head 41 corresponds to each row of material grids once, so that the material distribution of all the material grids can be completed in the unidirectional stepping process.
When the movable material grids are short of materials, the control system controls the movable material grids to move to the material supplementing position at the discharge port below the main material box 22, and material supplementing is achieved by controlling the action of the material supply valve 30.
After the material distribution step is completed, the grid material disc 54 moves to the position below an electromagnetic chuck of the discharging device along with the material disc positioning seat 13, the electromagnetic chuck moves downwards and is electrified, the grid material disc 54 and the turnover door are adsorbed and fixed, then the material disc positioning seat 13 returns, the electromagnetic chuck drives the grid material disc 54 to move downwards, the suction force of the electromagnetic chuck is reduced after the grid material disc moves in place, the turnover door is opened under the gravity action of the particles, the particles fall down, and the subsequent treatment is completed. Then, the electromagnetic chuck drives the grid tray 54 to move upwards, the tray positioning seat 13 moves to the position below the electromagnetic chuck, the electromagnetic chuck is powered off, and the grid tray 54 falls onto the tray positioning seat 13 again.
The particulate matter printing process is also one embodiment of the particulate matter printing method in the invention.
