Description

Technical Field

[0001] The present invention relates to the field of printing processing and drying, and in particular to a printing processing and drying machine with intelligent identification. Background Art

[0002] Printing processing dryer is a key equipment in printing post-processing, mainly used for fast drying of ink, improving production efficiency and quality of printed products. Although UV curing drying equipment can quickly cure ink, it has low flexibility in controlling temperature and humidity, and is only suitable for specific UV ink materials. Heat pump drying equipment can accurately control the temperature and humidity of the drying chamber, and automatically adjust the dehumidification damper and drying program through the intelligent system to ensure the stable drying of chemical raw materials such as printing ink and coating at sensitive temperatures. Therefore, it is widely used in the drying process of printing processing. However, when heat pump drying equipment uses hot air flow to dry printed products, when the overall thickness of the printed product is relatively thin, the hot air flow will continuously blow the surface of the printed product, causing it to continuously produce irregular shaking. This shaking phenomenon will cause the original local wrinkles on the surface of the printed product to further expand, affecting the shaping of the printing material on the printed product, resulting in blurred printing surface and pattern deformation after the printed product is dried, affecting the aesthetics of the printed product surface.

[0019] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, the movable straightening mechanism consists of a hollow connecting plate 42, an auxiliary suction plate 43, a pull rod 44 and a guide rail 45; a hollow connecting plate 42 is provided on each side of the main suction plate 41, and the hollow connecting plate 42 is connected to the corresponding main suction plate 41; an auxiliary suction plate 43 is slidably connected between the two hollow connecting plates 42, and the auxiliary suction plate 43 is connected to the two hollow connecting plates 42, and a plurality of auxiliary suction holes 4301 structures are provided on the auxiliary suction plate 43; a pull rod 44 is connected to the auxiliary suction plate 43; a guide rail 45 is fixed to the front and rear sides of the mounting frame 2, and the upper side of the guide rail 45 is an upwardly elongated semi-elliptical structure, and the two ends of the pull rod 44 are slidably connected to the corresponding guide rails 45.

[0020] Each hollow connecting plate 42 is slidably connected to the corresponding main suction plate 41; each auxiliary suction plate 43 is slidably connected to the corresponding pull rod 44, and the auxiliary suction plate 43 is configured as a two-way telescopic plate structure; Figure 9 As shown, when the staff pulls the two hollow connecting plates 42 to move away from each other along the main suction plate 41, the lateral length of the main suction hole 4101 exposed by the main suction plate 41 will increase. At the same time, the two hollow connecting plates 42 will drive the two auxiliary suction plates 43 to extend to both sides respectively, so that the length of the main suction hole 4101 exposed by the main suction plate 41 and the overall length of the auxiliary suction plate 43 are both lengthened, thereby being able to adapt to wider printed parts for corresponding suction work.

[0021] The working steps of the intelligent identification printing and processing dryer of the present invention are as follows.

[0022] First, the driving motor 31 drives the rotating frame 3 and the connected conveying drum 4 to rotate slowly clockwise in the front view angle. At the same time, the feeding electric conveyor 21 sequentially conveys the printed matter with the printed surface facing up to the right between the various blade structures of the conveying drum 4. The image intelligent recognition module 11 identifies the conveying status of the printed matter on the feeding electric conveyor 21 and intelligently determines whether the printed matter is successfully conveyed between the corresponding two blade structures in the conveying drum 4. If a material jam occurs, the image intelligent recognition module 11 sends a signal to the background to prompt The annular block 32 is provided with a raised structure 3201 which blocks the lower side of the annular diversion channel 303. When the electric conveyor 21 conveys the printed matter to the upper surface of the corresponding blade structure of the conveying drum 4, the main suction plate 41 on the blade structure is blocked by the raised structure 3201 and is not connected to the annular diversion channel 303. Therefore, the main suction hole 4101 of the corresponding main suction plate 41 on the blade structure does not generate an adsorption force on the printed matter. When the printed matter is inserted into the corresponding two holes in the conveying drum 4, the main suction hole 4101 of the main suction plate 41 on the blade structure does not generate an adsorption force on the printed matter. After the blade structures are aligned with the main suction plate 41, as the rotating frame 3 drives the conveying drum 4 to rotate, the main suction plate 41 on the blade structure supporting the printed matter leaves the protruding structure 3201, and the main suction plate 41 can be smoothly connected to the annular diversion channel 303. At this moment, the external vacuum suction machine generates suction force through the exhaust pipe 33 and the annular diversion channel 303 of the rotating frame 3 in sequence, so that the main suction hole 4101 of the main suction plate 41 can absorb the back of the printed matter, and then the rotating frame 3 drives the conveying drum 4 to suck the printed matter. The adsorbed printed matter is conveyed to the discharge electric conveyor 22 in a clockwise rotation at a front viewing angle. At the moment the printed matter is conveyed to the discharge electric conveyor 22, the corresponding main suction plate 41 on the blade structure supporting the printed matter is blocked by the protruding structure 3201 again, and the annular diversion channel 303 is not connected. Therefore, the main suction hole 4101 of the main suction plate 41 corresponding to the blade structure will no longer generate adsorption force on the printed matter, allowing the printed matter to detach from the main suction plate 41, and then the discharge electric conveyor 22 will convey the detached printed matter to the right for unloading.

[0023] As the rotating frame 3 drives the conveying drum 4 to convey the adsorbed printed matter to the discharge electric conveyor 22, the external hot air conveyor blows out a hot air flow through the air delivery channel 301, the through hole 302 and the air jet hole 401 of the rotating frame 3 in sequence. The hot air flow continuously flows outward along the surface of the printed matter to dry it. At the same time, the air pump built into the vacuum cylinder 12 discharges the waste gas carrying drying water and thermal volatile substances of the ink (substances produced by the thermal volatilization of the ink include: organic solvent volatiles such as benzene, esters, ketones, alcohols, and non-methane total hydrocarbons) into the air filter 13. After being purified by the filter layer (activated carbon and fine mesh layer) in the air filter 13, the waste gas is discharged through the exhaust pipe 14 to the external catalytic combustion chamber for catalytic combustion, thereby ensuring the purification of the waste gas and preventing the polluted waste gas generated during the drying process from being directly discharged into the outside world, causing environmental pollution problems. At the same time, a large amount of moisture is prevented from accumulating in the drying chamber 1, so that the drying chamber 1 remains dry and the printed matter is dried.

[0024] After the printed matter is inserted between the corresponding two blade structures in the conveying drum 4 and aligned with the main suction plate 41, since the length of the printed matter is greater than the length of the blade structure of the conveying drum 4, the back of the printed matter will be covered by the surface of the main suction plate 41 and the auxiliary suction plate 43 of the corresponding blade structure at the same time. When the rotating frame 3 drives the conveying drum 4 to transport the adsorbed printed matter to the discharge electric conveyor 22, the auxiliary suction plate 43 is connected to the main suction plate 41 through the hollow connecting plate 42, so the auxiliary suction plate 43 will also adsorb the printed matter from the back through the auxiliary suction hole 4301. The pull rod 44 moves along the blade structure of the conveying drum 4. Note that the pull rod 44 moves along the guide rail 45. During the upward movement of the pull rod 44 along the guide rail 45, the pull rod 44 is restricted by the guide rail 45 and will pull the auxiliary suction plate 43 to move outward along the back of the adsorbed printed matter. The auxiliary suction plate 43 moves outward relative to the hollow connecting plate 42. At this time, the auxiliary suction plate 43 flattens the printed matter outward from the back thereof, so that the printed matter is flattened into a complete plane structure. Under the continuous heat drying treatment of the printed matter by the hot air flow, the printed matter will be shaped by the heat into the pulled shape. The flat plane structure state eliminates the wrinkles of the printed matter itself and avoids the irregular shaking of the printed matter under the continuous blowing of the hot air flow during the heat drying process, which causes the wrinkles of the printed matter to further expand. It also prevents the printed surface from being blurred and the pattern from being deformed after the heat drying of the printed matter, which affects the aesthetics of the printed matter surface. It is explained here that when the pull rod 44 moves to the highest point of the guide track 45, the pull rod 44 will pull the auxiliary suction plate 43 away from the printed matter, and the printed matter will no longer be subject to the adsorption effect from the auxiliary suction plate 43. The end of the printed matter away from the conveying drum 4 will be in the natural Under the action of gravity, it deflects to the lower right at a small angle, away from the auxiliary suction plate 43, so that when the pull rod 44 moves downward along the guide track 45 to reset the auxiliary suction plate 43, the reset auxiliary suction plate 43 will no longer adsorb the printed matter. At this time, the hot air flow that continues to blow upward will cooperate with the blade structure of the conveying drum 4 to provide a stable supporting force to the deflected printed matter, so that the printed matter can remain stably adsorbed in the conveying drum 4. Since the printing surface of the printed matter has completed the heat setting treatment, the hot air flow that continuously flows through the surface of the printed matter will not affect the printing surface.

[0025] Example 2 On the basis of Example 1, Figure 1-Figure 7 and Figure 10As shown, each of the auxiliary suction plates 43 of the embodiment is provided with a number of scraping strips 4302 structures corresponding to the number of auxiliary suction holes 4301; each auxiliary suction hole 4301 is arranged on the corresponding scraping strip 4302 structure; each scraping strip 4302 structure is arranged as an inclined structure, and the scraping strip 4302 structures on the front side of the auxiliary suction plate 43 and the scraping strip 4302 structures on the rear side are symmetrically distributed; after the back surface of the printed matter is adsorbed by the auxiliary suction holes 4301 on the auxiliary suction plate 43, the pull rod 44 moves along the guide rail 45 and pulls the auxiliary suction plate 43 to move outward along the back surface of the printed matter, and in the process of vertically flattening the printed matter, the auxiliary suction plate 43 pushes the local wrinkle area on the back surface of the printed matter to be slowly flattened in the transverse direction through the inclined scraping strip 4302 structure, further improving the flattening effect of the printed matter, ensuring the flatness of the printed matter, and ensuring the surface beauty of the printed matter.

[0026] Embodiment 3 On the basis of embodiment 2, as shown in Figure 2 and Figure 3 As shown, the bottom of the mounting frame 2 of the embodiment is fixedly connected with a U-shaped baffle 5 which wraps the lower half of the conveying drum 4, and after the hot air flow is blown out from the main suction hole 4101 of the lower half of the conveying drum 4, it will be blocked by the U-shaped baffle 5, so that the heat of the part of the hot air flow is gathered between the lower half of the conveying drum 4 and the U-shaped baffle 5, so as to heat and keep warm the lower side of the leaf plate structure of the conveying drum 4, so that each leaf plate structure of the conveying drum 4 remains in a heated state and contacts the printed matter, when the printed matter contacts the heated leaf plate structure of the conveying drum 4, the heat on the leaf plate structure of the conveying drum 4 will be transferred to the printed matter, and after the printed matter is heated, the surface printing ink of the printed matter will be dried faster, so as to utilize the hot air flow which is blown out from the lower half of the conveying drum 4.

[0027] Since the U-shaped baffle 5 is located below the conveying drum 4, the air flow blown downward from the conveying drum 4 will flow to the left and right upper sides along the U-shaped baffle 5, and the air flow blown upward from the gap between the U-shaped baffle 5 and the conveying drum 4 will interfere with the conveying work of the printed matter conveyed on the feeding electric conveyor 21 and the discharging electric conveyor 22, therefore, the two ends of the U-shaped baffle 5 of the embodiment are respectively fixedly connected with a sealing baffle 51 which tightly contacts the corresponding leaf plate structure of the conveying drum 4, and the two sealing baffles 51 cooperate with the corresponding leaf plate structure of the conveying drum 4 and the U-shaped baffle 5 to form a closed drying space, so as to improve the heating and keeping warm effect of the lower side of the leaf plate structure of the conveying drum 4, and also avoid the air flow blown upward from the gap between the U-shaped baffle 5 and the conveying drum 4 to interfere with the conveying work of the printed matter conveyed on the feeding electric conveyor 21 and the discharging electric conveyor 22, so as to ensure that the printed matter conveyed on the feeding electric conveyor 21 and the discharging electric conveyor 22 can smoothly complete the conveying work.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
