a second motor 39 is arranged in the middle of the bottom end of the mesh plate 30, the second motor 39 is fixed at the top end of the bevel table 18, a cam 40 is mounted at the top end of an output shaft of the second motor 39, and the cam 40 is in sliding connection with the bottom end of the mesh plate 30;

the cam 40 is driven to rotate by the second motor 39, the mesh plate 30 is pushed to reciprocate at the top end of the oblique angle table 18, and printed matters are printed on the top end of the mesh plate 30 through reciprocating swing of the mesh plate 30, so that air below the mesh plate 30 is uniformly blown to the surfaces of the printed matters.

A plurality of second U-shaped pieces 37 distributed at equal intervals are installed at the top end of the mesh plate 30, the opening of each second U-shaped piece 37 faces downwards, and a U-shaped groove 35 is formed in the top surface of the mesh plate 30 and close to the bottom of the mesh plate 30.

Wherein, support the printed matter that falls into on the mesh board 30 top through second U-shaped piece 37, the top and the printed matter of second U-shaped piece 37 carry out the point contact to second U-shaped piece 37 all has certain elastic tension, can alleviate the impact when the printed matter falls down, supports through the point contact, reducible damage to printed matter surface printing ink.

The working principle is as follows: in the 3D printing machine provided by the invention, firstly, the printed substrate is arranged in the clamping groove of the clamping block, then, the top end of the printed substrate is locked and supported by the pressing strip 16, secondly, the printed matter is placed on a baffle 2 which is fixed on the right side of the printer main body 1 in an inclined way, and then the printed matter is conveyed into the printer main body 1 through a first conveying belt 3, then, the crank 5 rotates to drive the supporting arm 13 in the base plate hole to swing, so that the printing base plate is rapidly and reciprocally lifted in the base plate hole, the printing base plate prints the pattern texture at the bottom end on the surface of a printed matter through reciprocal lifting, in the printing process, the clamping bases 23 which can slide up and down on the two sides of the printed substrate are matched with the elastic tension generated by the first U-shaped sheet 32, so that the printed substrate can elastically slide on the side walls of the second clamping plates 15 on the two sides, and the printed substrate is prevented from being in hard contact with the surface of a printed matter; finally, the left side of the printing machine main body 1 is provided with the bevel angle table 18, the middle part of the bottom end of the bevel angle table 18 is provided with a plurality of air suction ports 25 communicated with the drainage grooves 28, the miniature electric fan in the air suction ports 25 blows air into the drainage grooves 28, the blown air is diffused through the arc-shaped surface of the bottom surface of the flow guide seat 29, the diffused air is guided through the drainage grooves 28, the wind power is blown out to the top end of the bevel angle table 18 and is uniformly diffused, the diffused air is blown out to the top end of the mesh plate 30 through the air inlet holes 36, the printed matter output by the printing machine main body 1 is favorably received through the mesh plate 30, the received printed matter surface is dried through the wind blown out from the air inlet holes 36 on the mesh plate 30, the cam 40 is matched with the second spring 42, the mesh plate 30 is lifted and reciprocated at the top end of the bevel angle table 18, the wind diffused by the drainage grooves 28 is accelerated to be, and finishing printing and drying the surface of the printed matter.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
