Description

Technical Field

[0001] This utility model relates to the field of screen printing tempered glass panel processing technology, and in particular to a drying device for screen printing tempered glass panel processing. Background Technology

[0002] Screen printing on tempered glass panels is a printing method that uses a screen printing plate to transfer ink or other pigments onto the surface of tempered glass through the mesh of the screen. This process can create a variety of exquisite, durable, and brightly colored patterns or text on tempered glass.

[0003] The printed tempered glass is placed in an oven or drying chamber to dry, allowing the solvent in the ink to evaporate and form a dry film. The dried tempered glass is then placed in a high-temperature furnace for sintering, allowing the pigments or glass powder in the ink to fuse with the surface of the tempered glass, enhancing adhesion and durability.

[0004] In existing technologies for drying screen-printed tempered glass panels, the heating elements inside the oven typically start working after the oven is preheated to the set temperature, generating heat to dry the glass panel. During the drying process, it is necessary to closely monitor the temperature inside the oven and the drying status of the glass panel. If abnormal temperature or uneven drying of the glass panel is detected, the drying parameters need to be adjusted in time or the glass panel needs to be repositioned. Such drying operations cannot effectively improve the uniformity of glass panel drying and also increase the workload of the workers. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device for screen-printed tempered glass panels, in which two sets of symmetrically arranged baffles rotate in opposite directions, thereby further disturbing the hot air blown out by the first and second circulating air pipes, thus improving the drying effect of the hot air and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for screen printing tempered glass panels, comprising a drying chamber, a sealing door panel hinged to the front end of the drying chamber, two vertically fixed assembly partitions fixedly installed inside the drying chamber, a plurality of assembly brackets fixedly installed on the inner side wall of the assembly partitions, a glass panel being snapped into the inside of the assembly brackets, and drying turbulence components provided on the upper and lower sides of the glass panel;

[0007] The drying turbulence assembly includes a support frame fixedly installed on the inner side wall of the assembly partition. A rotating shaft is rotatably installed inside the support frame, and turbulence baffles distributed in a ring are fixedly installed on the shaft wall.

[0008] Preferably, a circulating drying assembly is provided both inside and outside the drying chamber. The circulating drying assembly includes a heater fixedly installed on the top surface of the drying chamber. A hot air chamber is opened at the top inside the drying chamber, and the hot air chamber is connected to the output end of the heater.

[0009] Preferably, a plurality of second circulating air ducts are passed through the left side wall of the hot air chamber, and the ends of the second circulating air ducts are fixedly connected to second circulating air spray pipes. The second circulating air spray pipes are fixedly installed on the inner side wall of the assembly partition, and the second circulating air spray pipes correspond to each other with the turbulence air plate.

[0010] Preferably, a second circulating exhaust pipe is fixedly installed on the inner side wall of the assembly partition below the second circulating air pipe, and a circulating air chamber is formed between the side wall of the assembly partition away from the middle of the drying chamber and the inner side wall of the drying chamber.

[0011] Preferably, a plurality of first circulating air ducts are passed through the right side wall of the hot air chamber, and a first circulating air spray pipe is connected through the lower end of the first circulating air duct. The first circulating air spray pipe is fixedly installed on the inner side wall of the assembly partition, and the first circulating air spray pipe corresponds to the turbulence air plate.

[0012] Preferably, a first circulating exhaust pipe is fixedly installed on the inner side wall of the assembly partition above the first circulating air pipe.

[0014] Preferably, a regulating valve pipe is fixedly installed on the left side wall of the drying chamber, and the regulating valve pipe is interconnected with the circulating air chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a first circulating air pipe and a second circulating air pipe to evenly spray hot air, thereby enabling the organic solvents in the ink printed on the glass panel to evaporate, forming a dry film, ensuring a firm bond between the ink and the glass surface, and preventing the ink from falling off during subsequent processing or use.

[0017] 2. The first and second circulating air pipes of this utility model can drive the turbulence-dispersing air vanes to rotate on the rotating shaft. This turbulence-dispersing effect can be applied to the hot air blown out by the first and second circulating air pipes, so that the hot air can be evenly applied to the upper and lower surfaces of the glass panel, thereby further improving the uniform drying effect of the hot air.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A drying device for screen printing tempered glass panels includes a drying chamber 1. A sealing door 3 is hinged to the front end of the drying chamber 1. Two vertically fixed assembly partitions 4 are fixedly installed inside the drying chamber 1. Multiple assembly brackets 5 are fixedly installed on the inner side wall of the assembly partitions 4. Glass panels 6 are clamped inside the assembly brackets 5. Drying turbulence components 7 are arranged on the upper and lower sides of the glass panels 6. A circulating drying component 2 is arranged both inside and outside the drying chamber 1. The circulating drying component 2 includes a heater 201 fixedly installed on the top surface of the drying chamber 1. A hot air chamber 204 is opened at the top inside the drying chamber 1. The hot air chamber 204 is connected to the output end of the heater 201.

[0028] Multiple second circulation air ducts 208 penetrate the left side wall of the hot air chamber 204. The ends of the second circulation air ducts 208 are fixedly connected to second circulation air spray pipes 210. The second circulation air spray pipes 210 are fixedly installed on the inner side wall of the assembly partition 4. The second circulation air spray pipes 210 correspond to the baffle plate 703. Below the second circulation air spray pipes 210, a second circulation exhaust pipe 209 is fixedly installed on the inner side wall of the assembly partition 4. A circulation air chamber 212 is formed between the side wall of the assembly partition 4 away from the middle of the drying chamber 1 and the inner side wall of the drying chamber 1. Multiple first circulation air ducts penetrate the right side wall of the hot air chamber 204. 205. A first circulating air duct 205 has a first circulating air spray duct 207 connected to its lower end. The first circulating air spray duct 207 is fixedly installed on the inner wall of the assembly partition 4. Above the first circulating air spray duct 207, a first circulating exhaust pipe 206 is fixedly installed on the inner wall of the assembly partition 4. The assembly partition 4 has multiple connecting pipes 211. The first circulating exhaust pipe 206 and the second circulating exhaust pipe 209 are both connected to the circulating air chamber 212 through the connecting pipes 211. The rear end of the circulating air chamber 212 is fixedly connected to a circulating return pipe 203. A dehumidifier tank 202 is detachably installed at the top end of the circulating return pipe 203. A regulating valve pipe 8 is fixedly installed on the left side wall of the drying chamber 1. The regulating valve pipe 8 is connected to the circulating air chamber 212. The regulating valve pipe 8 can be used to control the emission of exhaust gas to maintain stable air quality and temperature in the drying area.

[0029] By adopting the above technical solution, during use, the sealing door 3 is opened, and the glass panel 6 to be dried is inserted into the symmetrically arranged assembly brackets 5. After the glass panel 6 is installed, the sealing door 3 is closed, and the heater 201 is started. The heater 201 can draw in outside air through the circulation return pipe 203, the circulation air chamber 212, and the regulating valve pipe 8. After the air circulation is complete, the regulating valve pipe 8 is closed. The heater 201 heats the air and transfers the heat to the hot air chamber 204. The superheated air chamber 204 is connected to the first circulating air duct 205, the first circulating air jet duct 207, the second circulating air duct 208, and the second circulating air jet duct 210. It should be noted that the first circulating air jet duct 207 and the second circulating air jet duct 210 have several evenly distributed through holes on their side walls near the center of the drying chamber 1, allowing for the even ejection of hot air. The even ejection of hot air through the first circulating air jet duct 207 and the second circulating air jet duct 210 enables the printing on the glass panel 6 to be evenly applied. The organic solvents in the brushed ink evaporate, forming a dry film that ensures a strong bond between the ink and the glass surface, preventing the ink from peeling off during subsequent processing or use. When hot air fills the middle part of the drying chamber 1, the hot air in the middle of the drying chamber 1 is discharged into the circulating air chamber 212 through the first circulating exhaust pipe 206, the second circulating exhaust pipe 209, and the connecting pipe 211. This achieves the recycling of hot air. It should be noted that the first circulating exhaust pipe 206 and the second circulating exhaust pipe 209 are located close to the interior of the drying chamber 1. Several evenly distributed exhaust holes are provided on the side wall in the middle position, so that hot air can flow into the first circulation exhaust pipe 206 and the second circulation exhaust pipe 209. When the heater 201 continuously draws air, the heater 201 can draw hot air from the circulation air chamber 212 through the circulation return pipe 203 to realize the circulation of hot air. The dehumidifier 202 is equipped with desiccant. When air passes through the desiccant inside the dehumidifier 202, the desiccant can absorb the moisture in the hot air to achieve the dehumidification effect.

[0030] Specifically, such as Figures 2 to 3 As shown, multiple sets of drying turbulence assemblies 7 are symmetrically arranged. Each drying turbulence assemblies 7 include a support frame 701 fixedly installed on the inner wall of the assembly partition 4. A rotating shaft 702 is rotatably installed inside the support frame 701. A ring-shaped turbulence deflector 703 is fixedly installed on the shaft wall of the rotating shaft 702. The first circulating air pipe 207 corresponds to the turbulence deflector 703, and the second circulating air pipe 210 corresponds to the turbulence deflector 703. The air force applied to the turbulence deflector 703 by the first circulating air pipe 207 and the second circulating air pipe 210 is greater than the resistance encountered by the turbulence deflector 703 in rotating, thereby enabling the turbulence deflector 703 to rotate. The support frame 701 provides support for the stable operation of the rotating shaft 702 and the turbulence deflector 703.

[0031] By adopting the above technical solution, during use, the first circulating air pipe 207 and the second circulating air pipe 210 can blow the turbulence vane 703 to rotate on the rotating shaft 702. This turbulence treatment can be applied to the hot air blown out by the first circulating air pipe 207 and the second circulating air pipe 210, so that the hot air can be evenly applied to the upper and lower surfaces of the glass panel 6, thereby further improving the uniform drying effect of the hot air. The drying turbulence components 7 on the sides of the first circulating air pipe 207 and the second circulating air pipe 210 are arranged in opposite directions. The first circulating air duct 207 and the second circulating air duct 210 are arranged diagonally opposite each other, which allows the two sets of symmetrically arranged baffles 703 to rotate in opposite directions. This secondary disturbance of the hot air blown out by the first circulating air duct 207 and the second circulating air duct 210 further improves the drying effect of the hot air, ensures the evaporation of organic solvents in the ink printed on the glass panel 6, forms a dry film, improves the firm adhesion between the ink and the glass surface, and prevents the ink from falling off during subsequent processing or use.

[0032] Working principle: In use, open the sealing door 3, insert the glass panel 6 to be dried into the symmetrically arranged mounting brackets 5. After the glass panel 6 is installed, close the sealing door 3 and start the heater 201. The heater 201 draws in outside air through the circulation return pipe 203, the circulation air chamber 212, and the regulating valve pipe 8. After the air circulation is complete, close the regulating valve pipe 8. The heater 201 heats the air and transfers the heat to the hot air chamber 204. The hot air chamber 204 connects to the first circulation air duct 205, the first circulation air spray pipe 207, the second circulation air duct 208, and the... Regarding the connection of the two circulating air pipes 210, it should be noted that the first circulating air pipe 207 and the second circulating air pipe 210 have several evenly distributed through holes on the side walls near the middle of the drying chamber 1, which facilitates the uniform ejection of hot air. The hot air is evenly ejected through the first circulating air pipe 207 and the second circulating air pipe 210. When the hot air fills the middle part of the drying chamber 1, the hot air in the middle of the drying chamber 1 will be discharged into the circulating air chamber 212 through the first circulating exhaust pipe 206, the second circulating exhaust pipe 209, and the connecting pipe 211. This achieves the recycling of hot air. It should be noted that the first circulating exhaust pipe 206 and the second circulating exhaust pipe 209 have several evenly distributed exhaust holes on their side walls near the middle of the interior of the drying chamber 1, allowing hot air to flow into them. When the heater 201 continuously draws air, it can extract hot air from the circulating air chamber 212 through the circulating return pipe 203, achieving hot air circulation. The first circulating air jet pipe 207 and the second circulating air jet pipe 210 can blow the turbulence vane 703 to rotate on the rotating shaft 702, thus improving the airflow of the first circulating air jet pipe 207 and the second circulating air jet pipe 210. The hot air blown out by the circulating air duct 210 is turbulent to ensure that the hot air acts evenly on the upper and lower surfaces of the glass panel 6, thereby further improving the uniform drying effect. The drying turbulence components 7 on the sides of the first circulating air duct 207 and the second circulating air duct 210 are symmetrically arranged, and the first circulating air duct 207 and the second circulating air duct 210 are arranged diagonally opposite each other. This allows the two sets of symmetrically arranged turbulence baffles 703 to rotate in opposite directions, which can further turbulent the hot air blown out by the first circulating air duct 207 and the second circulating air duct 210, thereby further improving the drying effect of the hot air.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
