Description

Technical Field

[0001] The present invention relates to the technical field of digital printing and screen printing integration, and particularly to a digital printing and screen printing integration device and a printing process. Background Art

[0002] Screen positioning printing achieves the mutual matching of different color contents through screen printing overprinting time after time. The most common problem is that a different screen plate needs to be prepared for each color. The dimensional stability and accuracy of the screen plate itself will affect the final overprinting result. Moreover, having a screen plate for each color greatly increases the time consumption and cost of the entire process, and it is also very easy to cause defective products. Digital printing requires a relatively high cost for the positioning process through a camera, and the positioning time is relatively long. There are very high requirements for aspects such as printing software, computer performance, and the resolution of the camera itself. General enterprises cannot operate or afford such a solution. Especially for multi-station matching, it is even more difficult. For this reason, a circulating feeding printer combining screen printing and digital inkjet has emerged;

[0003] Traditional circulating feeding printers combining screen printing and digital inkjet usually require manual or robotic arm to place the printing substrate. As Figure 1 shown, after positioning is completed, the suction platform is opened. The entire printing device starts printing the substrate at the starting position. After the substrate printing is completed, the substrate is taken away by manual or robotic arm and placed in a drying device. After the substrate drying is completed, it comes to the screen printing machine platform. The screen printing materials and the number of printing times depend on the product requirements. After all printing is completed, the substrate is placed in the drying device for drying to complete the printing process. Some substrates also require powder spreading operation by a powder spreading machine. Finally, the substrate adsorbed with hot melt powder completes the printing through the drying device;

[0004] The above process of combining screen printing and digital inkjet has the following problems:

[0005] 1. Excessive dependence on manual or robotic arm for loading and handling leads to a relatively long printing production line and an increase in the floor area occupied by the equipment;

[0006] 2. Deviation occurs in the substrate positioning printing during the handling process, which easily causes the pigments on the substrate to overlap or deviate during the screen printing process. Seriously, folding and overlapping problems occur on some substrates, resulting in the unqualified substrates after digital inkjet and screen printing, and there is a problem of blank space;

[0007] Therefore, we propose a digital printing and screen printing integration device and a printing process. Summary of the Invention

[0008] The purpose of the present invention is to provide a digital printing and screen printing integration device and a printing process to solve the problems raised in the above background art;

[0009] 1. By the feeding of the blanking mechanism in cooperation with the flipping of the rotating belt clamp, and then through the movement of the second conveyor belt and the first conveyor belt, the entire combined printing process is simplified, avoiding the problem of large floor area of traditional digital printing and screen printing integrated equipment;

[0010] 2. By fixing the base member to a unified template, it is convenient for the positioning of digital printing and screen printing equipment, and at the same time, it fixes the position of the base member itself, avoiding problems such as dislocation, deviation, and overlap of the base member during the printing process;

[0011] 3. By using the reverse brushing method for screen printing, the pigment contacts the substrate through the mesh holes and will not spread at the first moment under the action of gravity, and the distinction between pigments on the substrate is relatively clear and clean;

[0012] To achieve the above object, the present invention provides the following technical solutions:

[0013] An integrated device for digital printing and screen printing, including a working box, a printer, a first drying mechanism, a second drying mechanism, and a placing mechanism. Rotating platforms are symmetrically installed on both sides of the working box, and rotating belt clamps are movably connected to the rotating platforms through bearings. A transmission cavity is opened in the working box, and a top block is fixedly connected in the transmission cavity. A second conveyor belt is installed at the bottom of the top block in the transmission cavity, and a second drying mechanism is installed at the bottom of the second conveyor belt in the transmission cavity;

[0014] On the bottom inner wall of the transmission cavity and on one side of the second drying mechanism, first electric push rods are symmetrically fixed by bolts, and a receiving hopper is installed at one end of the first electric push rods. A pump is connected to the bottom of the receiving hopper, and a guide pipe is connected to one side of the pump. Second electric push rods are symmetrically fixed by bolts on both sides of the top of the receiving hopper, and a brush plate is fixed at one end of the second electric push rods. A scraping plate is installed on the top of the receiving hopper, and spraying columns are symmetrically installed on both sides of the scraping plate. One end of the guide pipe is communicated with the bottom of the spraying column;

[0015] An air suction platform is installed on one side of the top of the working box, and sliding grooves are symmetrically opened on both sides of the top of the air suction platform. A printer is installed on the top of the air suction platform. A telescopic block is slidably connected in the sliding grooves. A limiting strip is adhesively fixed on one side of the sliding grooves, and guide air pipes are uniformly installed on one side of the limiting strip. A rotating limiting piece is rotatably connected to one side of the top of the limiting strip through a bearing.

[0016] Furthermore, a first conveyor belt is installed on the top of the working box, a first drying mechanism is fixed by bolts on the top of the first conveyor belt and on the top of the working box, and a box door is installed on one side of the working box.

[0017] Furthermore, a blanking mechanism is installed at the top of the working box and on one side of the air suction platform. The blanking mechanism includes a base plate, a limiting rod, a slideway, a slider and a fixed roller. The base plate is fixed to the top of the working box, and a slideway is formed on the base plate. The top of the base plate is symmetrically fixed with limiting rods by spot welding. The top of one side of the base plate is symmetrically and slidably connected with sliders. The opposite surfaces of the two sliders are movably connected with a movable roller through bearings. One side of the base plate and at the bottom of the movable roller is movably connected with a fixed roller through a bearing. One side of the top of the base plate is slidably connected with a slide rod, and one end of the slide rod is connected to the slider. A first spring is sleeved on the slide rod at the top of the slider. A slide plate is installed on one side of the base plate, and placing mechanisms are evenly installed on the opposite surfaces of the limiting rods.

[0018] Furthermore, the placing mechanism includes a bottom plate, a placing table, a ventilation pipe, air suction holes and a cover plate. The placing table is installed on the top of the bottom plate, and air suction holes are evenly formed on the top of the placing table. One side of the bottom plate is evenly connected with ventilation pipes, and one end of the ventilation pipe penetrates through the placing table. The air suction holes are communicated with one side of the ventilation pipe. One side of the bottom plate is rotatably connected with a cover plate through a hinge, and a pressing strip is adhesively fixed on one side of the cover plate. Positioning blocks are evenly and symmetrically fixed on one side of the cover plate through bolts.

[0019] Furthermore, the blanking mechanism further includes a rotating shaft, a rotating rod and a resisting block. A resisting block is slidably connected in the slideway. The bottom inner wall of the base plate is movably connected with a rotating shaft through a bearing, and a special-shaped roller is sleeved and fixed on the rotating shaft. One side of the bottom inner wall of the base plate is rotatably connected with a rotating rod through a bearing, and one end of the rotating rod abuts against the resisting block. One side of the rotating rod is movably connected with a resisting wheel through a bearing, and one side of the resisting wheel abuts against one side of the special-shaped roller. A second spring is installed at the bottom of the base plate, and one end of the second spring is connected to one side of the rotating rod. One side of the fixed roller is connected with the rotating shaft through a belt.

[0020] A digital printing and screen printing integrated printing process:

[0021] Installation and blanking of the base member:

[0022] According to the different materials of the printing base member, when printing on a relatively soft textile material, first lay the part to be printed on the placing table, and then place the entire cover plate on the bottom plate, so that the entire pressing strip fixes the edge of the textile fabric exposed between the placing table and the bottom plate, and at the same time prevents the pressing strip from deforming the fabric. Always adjust the position of the fabric printed on the placing table;

[0023] The base plate with the printed fabric placed thereon is clamped onto the limiting rod, and the power device located at the bottom of the base plate is started. At this time, the entire rotating shaft starts to rotate, and at the same time, the rotating shaft drives the fixed roller to rotate through the belt. When the smooth side of the special-shaped roller on the rotating shaft contacts the abutting wheel on the rotating rod, it is affected by the second spring and pulls the rotating rod to rotate counterclockwise. One end of the rotating rod is connected to one side of the abutting block clamped in the slideway. At this time, the abutting block starts to move leftward for a certain distance and pushes the base plate clamped in the limiting rod onto the rotating fixed roller. Then, driven by the fixed roller and limited by the movable roller on the top of the base plate, the entire base plate with the base part slides down along the slide plate onto the air suction platform;

[0024] For paper panel printing, it is necessary to leave a blank area of 1 - 2 cm at the edge of the entire paper fabric, and cut a certain distance at the four corners, so that the entire cover plate presses the paper printing plate on the placement table and stacks it on the limiting rod on the surface of the base plate in the same way;

[0025] Digital printing and drying of the base part:

[0026] When the base plate with the base part falls onto the air suction platform, the telescopic block in the chute of the air suction platform drives the base plate in the entire limiting strip to move, and makes one side of the base plate abut against one side of the rotating limiting piece on the limiting strip. At this time, multiple air pipes on one side of the working box start to blow air. The high-speed flowing gas in the air pipes enters the placement table along the air vent pipe, and the gas is discharged from the other side of the placement table. According to the principle that the pressure is low where the flow rate is high, since multiple air suction holes are opened on the top of the entire placement table and a row of small air suction holes are connected to the air vent pipe in the placement table, the air suction holes generate suction force and suck the base part on the entire placement table tightly, avoiding deviation in the entire printing part during digital printing;

[0027] After the entire printer finishes printing the base part, at this time, the rotating limiting piece rotates and disengages from the limitation of one side of the base plate. The telescopic block in the chute pushes the entire preliminarily printed base plate into the rotating belt clamp block with a double-layer transmission belt, and the entire rotating table drives the rotating belt clamp block to rotate 180 degrees, and then sends the base plate onto the second conveyor belt in the transmission cavity. Inside the working box, and at the bottom of the second conveyor belt, a second drying mechanism is installed, and the second drying mechanism performs a drying operation on the base part after digital printing;

[0028] Silk screen printing and secondary drying of the base part:

[0029] Since positioning blocks are installed on the top of the entire cover plate, when the entire second conveyor belt drives the flipped bottom plate to move directly above the brush plate, the first electric push rod starts to work at this time, pushing the entire brush plate to lift the bottom plate and making one side of the bottom plate abut against the top block. When the entire first electric push rod continues to move upward, the brush plate presses down on the second electric push rod, causing the scraper on the top of the material receiving hopper to start contacting the mesh surface on the brush plate. Driven by the power device, the entire scraper starts to move left and right at the bottom of the brush plate. While the entire scraper is moving, the spraying column continuously sprays pigments onto the mesh surface. After being scraped by the scraper, part of the pigments pass through the mesh surface and fall onto the base parts on the bottom plate, completing screen printing;

[0030] After the operation, the bottom plate is flipped 180 degrees again by the rotating belt clamp and sent onto the first conveyor belt. After being dried by the first drying mechanism, the base parts on the entire bottom plate complete combined printing.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, through the material feeding of the feeding mechanism in cooperation with the flipping of the rotating belt clamp, and then through the movement of the second conveyor belt and the first conveyor belt, the base parts installed on the entire bottom plate perform complete digital printing and screen printing operations on the working box, greatly reducing the floor area of the entire digital printing and screen printing integrated device. At the same time, the rotating platforms on both sides of the working box can be disassembled and moved, facilitating separate digital printing or screen printing of the base materials, and the overall use of the device is relatively flexible;

[0033] 2. In the present invention, by fixing the base parts to a unified template, it is convenient for the positioning of digital printing and screen printing equipment, and at the same time, it plays a role in fixing the position of the base parts themselves, avoiding problems such as misalignment, deviation, and overlap of the base parts during the printing process, which affect the coloring of the base parts. At the same time, by connecting the air guide pipe with the air vent pipe on the bottom plate and using the principle that the pressure is low where the flow rate is large, suction is generated at the suction holes, sucking and fixing the base materials on the top of the entire placement table, avoiding the deviation or overlap of the base materials on the entire substrate during digital printing and improving the stability of the substrate during printing;

[0034] 3. In the present invention, by adopting the method of reverse brushing for screen printing, the pigments pass through the mesh holes and contact the substrate. Due to the action of gravity, they will not spread at the first moment. Therefore, the distinction between pigments on the substrate is relatively clear and clean. While using transmission vertical brushing, it is easy to cause the coincidence and blurring of the edges of pigments, affecting the overall quality of the printed substrate.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1-9 , the present invention provides a technical solution:

[0047] Embodiment 1:

[0048] For the integrated process of digital printing and screen printing, the most important thing is to solve the positioning printing of the base part on both of them. Secondly, it is the loading and unloading operation of the entire base part. The traditional process fails to handle the above two problems well, resulting in a large floor area of the entire integrated machine for digital printing and screen printing, low mechanical linkage, and the use of manual or robotic arms for loading and unloading.

[0049] For the above problems, as Figures 2-3 shown, the entire working box 1 adopts a double-layer belt circulating conveyor, and solves the problem between digital printing, screen printing and the positioning of the base part by fixing the base part to the placing mechanism 26. During specific operation, first place the base part that needs to be jointly printed by digital printing and screen printing on the placing mechanism 26. As Figure 6 shown, the main body of the entire placing mechanism 26 includes a bottom plate 261 and a cover plate 265. A placing table 262 is installed on the top of the bottom plate 261, and air suction holes 264 are evenly opened on the top of the placing table 262. A ventilation pipe 263 is evenly connected to one side of the entire placing table 262. The aperture of the air suction hole 264 is small and is connected to the ventilation pipe 263 inside the placing table 262.

[0050] A pressure strip 266 is fixed to one side of the entire cover plate 265. Four positioning blocks 267 are evenly and symmetrically installed on the other side of the cover plate 265 and are located at the four corners of the cover plate 265. For different fabrics of the base part, when printing on a softer textile fabric, first lay the part to be printed on the placing table 262, and then place the entire cover plate 265 on the bottom plate 261, so that the entire pressure strip 266 fixes the edge of the textile fabric exposed between the placing table 262 and the bottom plate 261, and at the same time prevents the pressure strip 266 from deforming the fabric by extrusion. Always adjust the printing position of the fabric on the placing table 262. For the printed material in the paper panel, a blank area of 1-2 cm needs to be reserved at the edge of the entire paper fabric, and a certain distance is cut at the four corners, so that the entire cover plate 265 presses the paper printing plate 23 on the placing table 262.

[0051] The connection operation between the base part and the placement mechanism 26 needs to be prepared in advance, and multiple base plates 261 with the base parts placed on them are uniformly placed on the blanking mechanism 4. By fixing the base parts to a unified template, it is convenient for the positioning of digital printing and screen printing equipment, and at the same time, it fixes the position of the base parts themselves, avoiding problems such as misalignment, deviation, and overlap of the base parts during the printing process, which may affect the coloring of the base parts.

[0052] Embodiment 2:

[0053] After waiting for the stacking of the placement mechanism 26 on the top limit rod 402 of the entire substrate 401 to end, as Figures 7-8 shown, start the power device located at the bottom of the substrate 401. The power device drives the rotation of the rotating shaft 410 on the inner wall of the bottom of the substrate 401, and a special-shaped roller 411 is sleeved and fixed on the entire rotating shaft 410. The entire special-shaped roller 411 is as Figure 8 shown. A flat cut is made on the roller. At the same time, a rotating rod 412 is rotatably connected to the inner wall of the bottom of the substrate 401 through a bearing. One side of the entire rotating rod 412 is movably connected to a pressing wheel 415 through a bearing, and one side of the pressing wheel 415 abuts against one side of the special-shaped roller 411. One end of the entire rotating rod 412 is clamped to the bottom of the abutting block 413 in the slideway 403 on the substrate 401. At the same time, a second spring 414 is installed on the inner wall of the top of the substrate 401, and one end of the second spring 414 is connected to one side of the rotating rod 412. Through the pulling of the second spring 414, the pressing wheel 415 and the special-shaped roller 411 always abut. However, when one side of the pressing wheel 415 contacts the smooth cutting part on the special-shaped roller 411, the rotating rod 412 rotates a certain angle. At the same time, one end of the rotating rod 412 drives the abutting block 413 in the slideway 403 to move a certain distance. One side of the entire abutting block 413 contacts the single base plate 261 at the bottom of the limit rod 402. Through the pushing of the abutting block 413, the bottommost base plate 261 stacked in the limit rod 402 is pushed out;

[0054] A slider 404 is slidably connected to one side of the top of the entire substrate 401, and a movable roller 405 is movably connected to the opposite surface of the slider 404. The top of the entire slider 404 is connected to a first spring 407. At the same time, one end of a slide bar 406 slidably connected to the top of the substrate 401 is connected to the slider 404. A fixed roller 408 is installed at the bottom of the movable roller 405. One side of the entire fixed roller 408 is connected to the rotating shaft 410 through a belt. When the entire rotating shaft 410 rotates, the entire fixed roller 408 will rotate. When a base plate 261 moves onto the fixed roller 408, it will be pushed to the left by the fixed roller 408, and the entire movable roller 405 that can move up and down prevents the base plate 261 from being misaligned. The base plate 261 rolling out from the movable roller 405 and the moving roller falls onto the air suction platform 8 at the top of the working box 1 along the slide plate 409;

[0055] AsFigure 4 As shown in the figure, limit bars 9 are symmetrically installed on the entire air suction platform 8. At the same time, a chute 10 is opened on one side of the limit bar 9. A telescopic block 11 that can move left and right is installed in the entire chute 10. A rotatable rotating limit piece 13 is installed on one side of the top of the limit bar 9. After the bottom plate 261 falls onto the air suction platform 8, the telescopic block 11 drives the bottom plate 261 on one side of the limit bar 9 to move on the air suction platform 8 until one side of the bottom plate 261 contacts one side of the rotating limit piece 13. At this time, the air pipe 263 on the placing table 262 is communicated with the air guide pipe 12 on the limit bar 9. Gas continuously enters the air pipe 263 from the air guide pipe 12. Also, because one side of the entire air suction hole 264 is connected to the air pipe 263, the gas in the entire air pipe 263 flows. Using the principle that the pressure is low where the flow rate is large, suction force is generated at the air suction hole 264, sucking and fixing the substrate on the top of the entire placing table 262, preventing the substrate of the entire substrate plate 401 from shifting or overlapping during digital printing and improving the stability during substrate printing;

[0056] After the initial printing of the printer 2 on the top of the substrate is completed, at this time, the rotating limit piece 13 stops abutting against the bottom plate 261. At the same time, the telescopic block 11 in the chute 10 pushes the printed substrate into the rotating belt clamp 14 on the rotating table 3. Two sets of belts are installed up and down in the entire rotating belt clamp 14 and can rotate forward and backward. After the entire bottom plate 261 enters the rotating belt clamp 14, the power equipment in the rotating table 3 drives the entire rotating belt clamp 14 to rotate 180 degrees. Since the substrate on the entire bottom plate 261 has just been digitally printed and the ink on the entire substrate is not yet dry, a drying operation is required at this time;

[0057] As Figure 3 shown in the figure, a transmission cavity 15 is opened in the entire working box 1, and a top block 16 is installed and fixed in the transmission cavity 15. A second conveyor belt 17 is installed at the bottom of the top block 16. The substrate printing side of the flipped bottom plate 261 faces downward, and the bottom plate 261 is sent onto the second conveyor belt 17 by the drive of the rotating belt clamp 14. Since a second drying mechanism 27 is installed at the bottom of the second conveyor belt 17 in the entire working box 1, the heat generated by the second drying mechanism 27 starts to dry the ink on the surface of the substrate. As Figure 5As shown, after the substrate on the entire second conveyor belt 17 is preliminarily dried, the second conveyor belt 17 drives the entire bottom plate 261 to move to the top of the receiving hopper 19. Since positioning blocks 267 are installed on the entire cover plate 265 and an identification mechanism is provided on the brush plate 23 at the top of the receiving hopper 19, when the identification mechanism corresponds to the positioning blocks 267, the first electric push rod 18 on the inner wall of the bottom of the working box 1 is started. At this time, the receiving hopper 19 and the brush plate 23 at the top of the receiving hopper 19 start to move upward. The receiving hopper 19 is connected to the brush plate 23 through the second electric push rod 22. When the brush plate 23 lifts the bottom plate 261 and separates it from the second conveyor belt 17, the bottom of the bottom plate 261 contacts the bottom of the top block 16. At this time, the entire second electric push rod 22 starts to contract, while the entire receiving hopper 19 is still rising. Since a scraper 25 that can move left and right is installed at the top of the entire receiving hopper 19 and spray columns 24 are connected to both sides of the scraper 25, when the scraper 25 contacts the brush plate 23, the power mechanism on one side of the top of the receiving hopper 19 drives the scraper 25 to move left. At the same time, the pump 20 at the bottom of the receiving hopper 19 sends the pigment along the guide pipe 21 into the spray columns 24. The pigment is evenly sprayed onto the forming mesh at the bottom of the brush plate 23 through the spray columns 24. After the left and right scraping of the scraper 25, part of the pigment that can pass through the mesh holes successfully falls onto the substrate on the bottom plate 261, completing the screen printing operation of the substrate. Part of the pigment that falls from the silk screen enters the receiving hopper 19 and will eventually flow into the pump 20 for recycling. The screen printing is carried out in the reverse brushing method. The pigment passes through the mesh holes and contacts the substrate. Due to the gravitational force, it will not spread at the first moment. Therefore, the distinction between the pigments on the substrate is relatively clear and clean. However, when using the transmission vertical brushing, it is easy to cause the edges of the pigments to overlap and blur, affecting the quality of the substrate after printing;

[0058] A box door 7 is provided in the entire working box 1 at the position of the brush plate 23, which is convenient for the later replacement of the brush plate 23 by the staff. After the screen printing, the substrate without the abutment of the brush plate 23 falls onto the second conveyor belt 17 and is sent to the rotating belt clamp 14 by the second conveyor belt 17. After being flipped 180 degrees by the other rotating belt clamp 14, the printed substrate successfully comes to the top of the working box 1, as Figure 2 shown. A first conveyor belt 5 is installed at the top of the entire working box 1. The rotating belt clamp 14 sends the bottom plate 261 onto the first conveyor belt 5. At the same time, a first drying mechanism 6 is installed at the top of the entire first conveyor belt 5. Through the drying treatment of the first drying mechanism 6, the pigment on the surface of the substrate after screen printing solidifies. Finally, the bottom plate 261 with the completely printed base member is sent to the bottom of the substrate 401 through the first conveyor belt 5. The staff takes out the base member on the bottom plate 261 and places the new substrate to be printed on the limiting rod 402;

[0059] As Figure 9The digital printing and screen printing of the entire substrate shown are relatively uniformly concentrated on the working box 1, greatly reducing the floor area of the entire digital printing and screen printing integrated device. At the same time, the rotating platforms 3 on both sides of the working box 1 can be disassembled and moved, facilitating separate digital printing or screen printing of the substrate, and the overall use of the device is relatively flexible.

4. The integrated device for digital printing and screen printing according to claim 3, characterized in that: The printing process of this digital printing and screen printing integrated device includes: Installation and blanking of the base part: According to the different materials of the printing base parts, when printing on soft textile fabrics, first lay the part to be printed on the placement table, and then place the entire cover plate on the bottom plate, so that the entire pressing strip fixes the edge of the soft fabric exposed between the placement table and the bottom plate, and at the same time prevents the pressing strip from deforming the soft fabric. Continuously adjust the printing position of the soft fabric on the placement table. Clamp the entire bottom plate with the printed fabric onto the limiting rod, and start the power device at the bottom of the base plate. At this time, the entire rotating shaft starts to rotate, and at the same time the rotating shaft drives the fixed roller to rotate through the belt. When the smooth side of the special-shaped roller on the rotating shaft contacts the resisting wheel on the rotating rod, it is affected by the second spring and pulls the rotating rod to rotate counterclockwise. One end of the rotating rod is connected to one side of the resisting block clamped in the slideway. At this time, the resisting block starts to move leftward for a certain distance, and pushes the bottom plate clamped in the limiting rod onto the rotating fixed roller. Then, driven by the fixed roller and limited by the movable roller on the top of the bottom plate, the entire bottom plate with the base part slides down along the slide plate onto the air suction platform. For paper panel printing, a blank area of 1 - 2 cm needs to be reserved at the edge of the entire paper fabric, and a certain distance is cut at the four corners, so that the entire cover plate presses the paper printing plate on the placement table, and it is also stacked and placed on the limiting rod on the surface of the bottom plate. Digital printing and drying of the base part: When the entire bottom plate with the base part falls onto the air suction platform, the telescopic block in the chute of the air suction platform drives the bottom plate in the limiting strip to move, and makes one side of the bottom plate abut against one side of the rotating limiting piece on the limiting strip. At this time, multiple air pipes on one side of the working box start to blow air. The high-speed flowing gas in the air pipes enters the placement table along the ventilation pipe, and the gas is discharged from the other side of the placement table. According to the principle that the pressure is low where the flow rate is high, since multiple suction holes are opened on the top of the placement table and a row of small suction holes are connected to the ventilation pipe in the placement table, the suction holes generate suction force and suck the base part on the entire placement table tightly, avoiding deviation in the entire printing part during digital printing. After the entire printer finishes printing on the base member, the limit piece rotates at this time and disengages from the limit on one side of the bottom plate. The telescopic block located in the chute pushes the entire preliminarily printed bottom plate into the rotating belt clamping block with a double-layer transmission belt. The entire rotating table drives the entire rotating belt clamping block to rotate 180 degrees, and then sends the bottom plate onto the second conveyor belt in the transmission cavity. Inside the working box, and a second drying mechanism is installed at the bottom of the second conveyor belt. The second drying mechanism performs a drying operation on the base member after digital printing; Silk screen printing and secondary drying of the base member: Since a positioning block is installed on the top of the entire cover plate, when the entire second conveyor belt drives the flipped bottom plate to move directly above the brush plate, the first electric push rod starts to work at this time, pushing the entire brush plate to lift the bottom plate and making one side of the bottom plate abut against the top block. When the entire first electric push rod continues to move upward, the brush plate presses down on the second electric push rod, causing the squeegee on the top of the material receiving hopper to start contacting the mesh surface on the brush plate. Driven by the power device, the entire squeegee starts to move left and right at the bottom of the brush plate. While the entire squeegee is moving, the spray column continuously sprays ink onto the mesh surface. After being scraped by the squeegee, part of the ink passes through the mesh surface and falls onto the base member on the bottom plate, completing silk screen printing; The bottom plate after completion is flipped 180 degrees again through the rotating belt clamping block and sent onto the first conveyor belt, and then dried by the first drying mechanism, so that the base member on the entire bottom plate completes combined printing.
