[0023] The utility model discloses a printing device for packing and printing, including work table 1, work table 1 back is provided with shift control mechanism 2, and shift control mechanism 2 output end is installed with fixed arm 3, and the squeege 4, and the fixed mounting of silk screen printing plate assembly 5 is installed on fixed arm 3, and shift control mechanism 2 is used for controlling fixed arm 3 to go up and down, and the squeege 4 reciprocatingly shifts, its characterized in that: silk screen printing plate assembly 5 includes fixed frame 51, and the inner wall fixed connection of fixed frame 51 has main body silk screen printing plate 52, and automatic ink outlet mechanism 6 is fixedly installed on one side of the top of fixed frame 51, and automatic ink outlet mechanism 6 includes ink storage box 61, telescopic ink pumping mechanism 62, ink discharge head assembly 63, and telescopic ink pumping mechanism 62 is provided with two, and the telescopic end is connected with ink discharge head assembly 63 front and rear end respectively, and the inside of ink discharge head assembly 63 is docked with the inside of ink storage box 61 through telescopic ink pumping mechanism 62, and telescopic ink pumping mechanism 62 telescopic is used for pumping the ink in the inside of ink storage box 61 to the inside transmission of ink discharge head assembly 63, and ink discharge head assembly 63 extends to the above of main body silk screen printing plate 52.

[0024] Refer to Figure 3 , ink discharge head assembly 63 includes ink discharge box 631, and the sliding slot that is seted up in one side of ink discharge box 631 penetrates to the inside, and the sliding slot is sleeved with the pressing plate 632, and the other side of ink discharge box 631 is connected with transfer mechanism 635, and the bottom of ink discharge box 631 is provided with the ink outlet that communicates inside, and the ink outlet is provided with flap assembly 634, and the pressing plate 632 is drivenly connected with the inner wall of ink discharge box 631 through a plurality of springs 633.

[0025] When the ink pumped out by the telescopic ink pumping mechanism 62 reaches the internal storage of the ink outlet box 631, it is closed by the flap assembly 634. After the squeegee 4 contacts the ink outlet head assembly 63, pressure is applied to the pressing plate 632, which is extruded to the inner wall of the ink outlet box 631, causing the internal space to shrink. The internal ink is extruded to the flap assembly 634, causing it to flip. Then the ink can be discharged from the bottom of the ink outlet box 631, achieving the effect of ink filling. Because the pressing plate 632 occupies the internal space of the ink outlet box 631 when it is pressed, the ink pumped out by the telescopic ink pumping mechanism 62 cannot enter, so the transfer mechanism 635 is set up to temporarily store the pumped-out ink. When the pressing plate 632 is not pressed, it is reset by the spring 633, and then the temporarily stored ink in the transfer mechanism 635 automatically enters the internal filling of the ink outlet box 631, completing the next cycle of ink filling.

[0026] Referring to Figure 4 , the flap assembly 634 includes a fixed shaft 341 fixedly connected to the inner wall of the ink outlet of the ink outlet box 631. The side wall of the fixed shaft 341 is rotatably sleeved with a sleeve 342. One side of the sleeve 342 is fixedly connected with a main plate 343. The two ends of the sleeve 342 are respectively connected with a torsional spring 344 and the inner wall of the ink outlet through transmission.

[0027] When the pressing plate 632 applies pressure to the internal space of the ink outlet box 631, the main plate 343 is flipped by the pressure of the ink. At this time, the ink outlet is opened. When the pressing plate 632 is reset, the main plate 343 can be reset under the torsional force of the torsional spring 344, resealing the ink outlet.

[0028] Referring to Figure 5 , the transfer mechanism 635 includes a housing 351, which is internally provided with an ink storage space and an ink outlet space. The ink storage space is slidably sleeved with a moving disc 352. One side of the moving disc 352 is connected with the inner wall of the housing 351 through a spring 353. The side wall of the moving disc 352 is provided with a plurality of ink guide grooves 357 communicating with the other side of the moving disc 352. The side wall of the housing 351 is provided with a hollow ring 356. The side wall of the hollow ring 356 is provided with two inlet holes communicating with the inside. The inner wall of the hollow ring 356 is provided with a plurality of outlet holes communicating with the inside. The outlet holes are connected with the inside of the housing 351 through a plurality of connecting pipes 354. The plurality of connecting pipes 354 are aligned with the plurality of ink guide grooves 357.

[0029] The ink pumped by the telescopic ink pumping mechanism 62 enters through the hole of the hollow ring 356 and is discharged into the ink guide grooves 357 through the connecting pipes 354. At this time, the ink is collected in the other direction of the ink guide grooves 357. Since the internal space of the ink outlet box 631 is blocked, the ink cannot flow into the internal space of the ink outlet box 631 through the ink outlet space. At this time, as the amount of ink increases, the movable disc 352 can be displaced by being extruded, achieving the effect of storing ink in the ink storage space of the shell 351. When the internal space of the ink outlet box 631 is blocked, the ink in the storage space can be extruded into the ink outlet space of the shell 351 under the elastic effect of the second spring 353, and then introduced into the internal space of the ink outlet box 631, thereby achieving the effect of temporarily storing ink by the transfer mechanism 635.

[0030] With reference to Figure 5 , the ink outlet space of the shell 351 is divided into a column hole a and a column hole b. The diameter of the column hole a is smaller than the diameter of the column hole b. The column hole b is provided with a check plate 358. The diameter of the check plate 358 is smaller than the diameter of the column hole b and larger than the diameter of the column hole a. One side of the check plate 358 is in transmission connection with the inner wall of the column hole a through the tension spring 355.

[0031] Under the tension effect of the tension spring 355, the check plate 358 can block the column hole a to prevent the ink discharged by the transfer mechanism 635 from flowing back. When the movable disc 352 extrudes the ink in the ink storage space of the shell 351, the ink extrudes and displaces the check plate 358. At this time, the ink can be discharged through the column hole a and flow out of the ink outlet space through the gap between the check plate 358 and the column hole b.

[0032] With reference to Figure 6 , the telescopic ink pumping mechanism 62 comprises a cylinder shell 621. The inner cavity of the cylinder shell 621 is provided with a piston rod 622. One end of the piston rod 622 penetrates through one side of the cylinder shell 621 and is connected with a side plate 624. The side plate 624 is in transmission connection with the piston rod 622 through the third spring 623. The side wall of the cylinder shell 621 is respectively provided with a one-way valve one 625 and a one-way valve two 626 which are in communication with the inner cavity of the cylinder shell 621. The one-way valve one 625 is in communication with the internal space of the ink storage box 61 through a hose one 627. The one-way valve two 626 is in communication with the ink outlet head assembly 63 through a hose two 628.

[0033] The telescopic ink pumping mechanism 62 is used by being pressed and displaced to drive the piston rod 622 to slide in the inner cavity of the cylinder shell 621 and compress the space thereof. The gas is discharged from the one-way valve two 626. Under the elastic effect of the third spring 623, the piston rod 622 is reset. At this time, the inner cavity of the cylinder shell 621 forms a negative pressure suction force. The ink in the internal space of the ink storage box 61 is extracted through the one-way valve one 625 and enters the internal space of the cylinder shell 621 through the hose one 627. When the next cycle, the piston rod 622 is retracted to compress the internal space of the cylinder shell 621, so that the ink is pressed out through the one-way valve two 626 and introduced into the ink outlet head assembly 63 through the hose two 628.

[0034] With reference to Figure 6The one-way valve one 625 only flows to the inner cavity of the barrel shell 621, and the one-way valve two 626 only flows to the outside of the barrel shell 621.
