Description

Technical Field

[0001] The invention relates to a baking device, in particular to a baking device for the surface of a glass bottle applied in the technical field of glass bottle manufacturing. Background Art

[0002] The baking process is a process of decorating the surface of glass bottles. Usually, colored decals or printed patterns are pasted on the surface of the glass bottles, and then they are baked at high temperature in a baking furnace to fix the patterns on the surface of the glass bottles.

[0003] The color of the pattern on the decal paper is mainly transferred to the glass bottle through the principle of thermal sublimation, and this process does not involve chemical reactions. The pigment on the decal paper sublimates after being heated, becomes gaseous, and adheres to the surface of the glass bottle to form various patterns or texts. Therefore, the flatness of the decal paper on the surface of the glass bottle directly affects the quality of the decal. Traditional decal equipment is easy to leave bubbles that are not easily detected by the human eye after pasting, and cannot be smoothed in time. After being sent to the baking oven, the bubbles expand after heating, causing the pigment to be misplaced and even causing the glass bottle to be unevenly heated and broken. Summary of the invention

The input end of the control module is respectively connected to a temperature monitoring module, a bubble recognition module and a pressure monitoring module, wherein the input end of the temperature monitoring module is connected to the temperature sensor 25, the bubble recognition module is connected to the recognition camera 16, and the input end of the pressure monitoring module is connected to the pressure sensor 15; the output end of the control module is respectively connected to a rotation adjustment module, a pressure adjustment module and a temperature adjustment module, the output end of the rotation adjustment module is connected to the drive motor 9, the pressure adjustment module is connected to the electric telescopic cylinder 14, and the temperature adjustment module is connected to the heating plate 102.

[0019] For details, please refer to Figure 4 , Figure 8 and Fig. 9 The method for using the glass bottle surface baking device includes the following steps: Step 1: loading, heating and identifying bubbles; placing the glass bottle body 3 with the baked flower sticker 301 bonded thereto on the rotating table 4, closing the door panel 101, starting the heating plate 102, the driving motor 9 and the identification camera 16 through the control terminal 38, so that the temperature in the baking oven 1 gradually increases, and monitoring the temperature in real time through the temperature sensor 25, controlling the maximum temperature to be lower than the sublimation temperature of the pigment on the baked flower sticker 301, continuously photographing the baked flower sticker 301 through the identification camera 16, and extracting bubble features in the photographed image; It should be noted that the recognition camera 16 continuously shoots the glass bottle body 3 in the rotating process, and transmits the captured images to the bubble recognition module, which searches for bubbles in the captured images according to the stored bubble features, and transmits the found bubble information to the control module; in addition, for obtaining the bubble features, the surface of the baking paper with bubbles will be distorted, and the image difference can be obtained by comparing it with the captured image in the bubble-free state, and a large number of image differences at different positions are obtained through a large number of repeated experiments, and the image difference is the bubble feature data; Step 2: squeeze out the air and adjust the squeezing pressure according to the bubble discharge situation; when the bubbles in the baked sticker 301 are identified, the electric telescopic cylinder 14 is started through the control terminal 38, and the electric telescopic cylinder 14 drives the movable frame 13 to move toward the direction of the glass bottle body 3, and the movable frame 13 drives the roller frame 11 and the squeezing roller 10 installed thereon to move toward the direction of the glass bottle body 3 through the spring telescopic rod 12.

[0034] Second implementation method: Figure 10-11A device for baking patterns on the surface of a glass bottle is shown. Based on the first embodiment, a blowing mechanism is installed on the upper part of the baking furnace 1. The blowing mechanism blows the upper airflow in the baking furnace 1 to the inside of the glass bottle body 3, thereby reducing the temperature difference between the inner and outer walls of the glass bottle body 3, accelerating the expansion of the bubbles when squeezing them, reducing the temperature difference when baking the patterns, and avoiding the glass bottle body 3 from breaking.

[0035] See also Fig.11 The blowing mechanism includes a blowing tube 26, in which a piston disk 27 slidably connected thereto is nested, and the piston disk 27 is fixedly connected to the top plate of the baking oven 1 through a support rod; an exhaust pipe 28 is connected to the upper part of the blowing tube 26, and a first non-return valve 29 is provided at the connection between the exhaust pipe 28 and the blowing tube 26; an air outlet 30 is provided on the piston disk 27 and passes through it, and the air outlet 30 is connected to a hose 32 through a second non-return valve 31 fixed on the piston disk 27, and the lower end of the hose 32 is connected to an air injection pipe 2601 integrally formed with the blowing tube 26; the blowing tube 26 is connected to a driving mechanism for driving it to move up and down.

[0036] Specifically, the driving mechanism drives the blowing tube 26 to move up and down. When the blowing tube 2601 moves downward and is inserted into the interior of the glass bottle body 3, the blowing tube 26 cooperates with the piston disk 27 to squeeze the airflow in the cavity above the piston disk 27. The squeezed airflow is injected into the jet pipe 2601 through the air outlet 30, the second one-way valve 31 and the hose 32, and finally injected into the interior of the glass bottle body 3 from the jet pipe 2601; when the driving mechanism drives the blowing tube 26 to move upward, the blowing tube 26 draws the hot air flow on the upper part of the baking furnace 1 into the blowing tube 26 through the exhaust pipe 28, and repeats the above process to inject the hot air flow gathered in the upper part of the inner cavity of the baking furnace 1 into the glass bottle body 3, thereby increasing the heating rate of the glass bottle body 3 while reducing the temperature difference between the inner and outer walls, thereby improving safety.

[0037] See also Fig.10 The driving mechanism includes a lifting frame 33 fixedly connected to the blowing tube 26 and passing through the top plate of the baking oven 1. The lifting frame 33 is clamped with an eccentric groove disk 34. The eccentric groove disk 34 is connected to the second vertical transmission shaft 36 through a first horizontal transmission shaft 35 and a transmission gear set. The second vertical transmission shaft 36 is connected to the second horizontal transmission shaft 37 through a transmission gear set. The second horizontal transmission shaft 37 is meshed with the first gear 7 through a transmission gear for transmission.

[0038] Specifically, when the driving motor 9 drives the first gear 7 to rotate through the second gear 8, and the first gear 7 drives the rotating table 4 and the glass bottle body 3 thereon to rotate through the support shaft 6, the first gear 7 drives the second horizontal transmission shaft 37 to rotate through the transmission gear, and the second horizontal transmission shaft 37 drives the eccentric groove disk 34 to rotate through the second vertical transmission shaft 36 and the first horizontal transmission shaft 35, and the eccentric groove disk 34 drives the blowing tube 26 to move up and down through the lifting frame 33.

[0039] It should be noted that, by adopting the ratchet gear 24, when the drive motor 9 reverses, the first gear 7 cannot drive the ratchet gear 24 to rotate, that is, when the drive motor 9 reverses, the extrusion roller 10 cannot rotate, thereby avoiding power waste of the drive motor 9. Specifically, after the extrusion exhaust is completed, the extrusion roller 10 does not need to rotate.

[0040] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
