Description

Technical Field

[0001] This invention relates to the field of bottle production and conveying technology, and more specifically, to an automatic spray coating and drying production line for liquor bottles. Background Technology

[0002] During the production of liquor bottles, the bottle body needs to be sprayed with paint to change its appearance and enhance its aesthetics. After spraying, a drying process is performed to allow the paint to cure quickly. Existing spraying equipment usually has separate spraying and drying stations. After spraying, the glass bottles are transferred, and during the transfer process, the paint on the liquor bottles flows, creating textures, unevenness, and may even mix in dust and impurities from the air, affecting the quality of the paint surface.

[0003] In the prior art, such as the utility model patent with publication number CN219560119U, a spraying equipment for processing liquor glass bottles is disclosed. A dryer is installed on the top wall of the spraying rack, and a drying pipe is installed on one side of a partition. One end of the drying pipe is connected to the air outlet of the dryer, and drying ports are arranged at equal intervals on one side of the drying pipe. After the liquor glass bottle is sprayed, the dryer is started, and the hot air generated by the dryer enters the drying pipe and is then blown onto the outer surface of the liquor glass bottle through the drying ports, accelerating the film formation speed of the paint. This spraying equipment integrates the spraying and drying processes into the same station, improving the production efficiency of liquor glass bottles. However, in actual use, workers manually place the liquor bottles, resulting in unsatisfactory work efficiency.

[0059] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0060] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0061] Example 1:

[0062] like Figure 1 As shown, this invention provides an automatic spray coating and drying production line for liquor bottles, comprising:

[0063] Conveying unit 1 is used to carry the liquor bottle 2 and transport it to a preset station. Multiple bottle holders 3 are provided on the conveying unit 1, and the liquor bottle 2 is placed upside down on the bottle holders 3.

[0064] The AGV loading unit uses a loading robot 4 to transfer the liquor bottles 2 on the AGV rack 5 to the bottle holder 3.

[0065] The spraying and drying unit 6 is used to spray and dry the liquor bottle 2, and the conveying unit 1 passes through the spraying and drying unit 6.

[0066] The working principle and beneficial effects of the above technical solution are as follows:

[0067] This invention provides an automated spray coating and drying production line for liquor bottles. An AGV (Automated Guided Vehicle) feeding unit is used to feed the liquor bottles during the spray coating and drying process. The AGV rack 5 is transferred from the previous production process to the spray coating and drying production line and automatically stops at a preset position. The feeding robot 4 clamps and inverts the liquor bottles 2 on the AGV rack 5, placing them on the bottle holder 3. The conveying unit 1 is activated to transport the bottle holder 3 to the spray coating and drying unit 6, where spray coating and drying operations are performed in a sealed space. After drying is completed, the conveying unit 1 delivers the finished product.

[0068] Through the above structural design, based on the coordinated operation of AGV automatic feeding and conveying unit 1, the liquor bottle 2 to be sprayed is conveyed to the spraying and drying unit 6 for drying. The spraying and drying unit 6 integrates spraying components and drying components, which can perform drying operations in a timely manner after the spraying operation is completed, thereby improving the efficiency of the complete curing of the paint on the body of the liquor bottle 2 and the quality of the paint surface on the liquor bottle 2.

[0069] Example 2:

[0070] like Figure 1 As shown, based on the above embodiment 1, the spraying and drying unit 6 includes:

[0071] Spray drying oven 11, which is equipped with a spraying component and a UV drying component;

[0072] Electric protective door 12 is installed at the inlet and outlet of the spray drying chamber 11; the electric protective door 12 seals the spray drying chamber 11 when closed.

[0073] The working principle and beneficial effects of the above technical solution are as follows:

[0074] When the spray drying unit 6 is in use, electric protective doors 12 are installed at the inlet and outlet of the spray drying box 11. When the liquor bottle 2 enters the spray drying box 11 for painting and drying operations, the electric protective doors 12 are closed, making the spray drying box 11 close to a sealed state. On the one hand, the sealed space helps to improve drying efficiency, and on the other hand, it effectively prevents harmful substances from overflowing during the painting process, reducing environmental pollution and harm to the workers.

[0075] Example 3:

[0076] like Figure 2 As shown, based on the above embodiment 2, the spraying assembly includes:

[0077] Electric slide rail 13 is installed on both sides of spray drying box 11. A slider is slidably installed inside the electric slide rail 13 and the slider is connected to the spray head 14. The spray head 14 is connected to the paint supply equipment through a pipe. The electric slide rail 13 includes a lower vertical section and an upper arc section, and the arc section bends downward.

[0078] The working principle and beneficial effects of the above technical solution are as follows:

[0079] When the spraying assembly is in use, the electric slide rail 13 drives the slider to move, and the slider drives the nozzle 14 to move. Guided by the vertical section of the electric slide rail 13, the nozzle 14 is adjusted to different heights so that the nozzle 14 can spray the liquor bottle 2 at various heights. Guided by the arc section of the electric slide rail 13, the spraying angle is changed as the nozzle 14 moves upward, which can better adapt to the curvature of the bottom of the liquor bottle 2, reduce the spraying dead angles at the transition between the bottle body and the bottom and the bottom of the bottle, and effectively adapt to the spraying requirements of different liquor bottles.

[0080] Example 4:

[0081] like Figure 2 As shown, based on the above embodiment 1, the spraying assembly further includes:

[0082] The first motor 15 is installed on the bottom wall of the spray drying oven 11;

[0083] The first rotating shaft 16, two first rotating shafts 16 are rotatably connected to the bottom of the spray drying box 11, and one of the first rotating shafts 16 is connected to the output end of the first motor 15;

[0084] The pulley assembly includes two pulleys 17 and a synchronous belt 18 surrounding the two pulleys 17. The two pulleys 17 are respectively connected to two first rotating shafts 16.

[0085] The spraying assembly also includes: a clutch mechanism 20, which is located at the top of the first rotating shaft 16; the edge of the bottle holder 3 is connected to the conveying unit 1, and the center of the bottle holder 3 is rotatably connected to the second rotating shaft 19, which is connected to the liquor bottle 2; the clutch mechanism 20 controls the connection and separation of the first rotating shaft 16 and the second rotating shaft 19.

[0086] The working principle and beneficial effects of the above technical solution are as follows:

[0087] After the conveying unit 1 transports the bottle holders 3 to the preset spraying position in the spray drying box 11, the conveying unit 1 stops operating, and the bottle holders 3 on the conveying unit 1 are arranged in two rows side by side; the clutch mechanism 20 above the first rotating shaft 16 is activated and connected to the second rotating shaft 19, so that the second rotating shaft 19 can rotate synchronously with the first rotating shaft 16; the liquor bottle 2 is installed on the second rotating shaft 19 and rotates synchronously with the second rotating shaft 19. During the spraying operation, the first motor 15 is started synchronously. The first motor 15 drives one of the first rotating shafts 16 to rotate, and drives the other first rotating shaft 16 to rotate through the pulley group. The first rotating shaft 16 drives the liquor bottle 2 to rotate, that is, during spraying, the liquor bottle 2 can rotate around its own axis, so that the paint is evenly sprayed on the body of the liquor bottle 2, improving the spraying effect.

[0088] Example 5:

[0089] like Figure 2 As shown, based on the above embodiment 2, the UV drying assembly includes:

[0090] A protective cover 21 is provided at the top of the spray drying oven 11, and a receiving groove 22 is provided at the bottom of the protective cover 21.

[0091] UV lamp holder 23 is connected to the bottom of protective cover 21 via a lifting mechanism. UV lamp holder 23 can be completely stored in receiving slot 22. Multiple UV lamps 24 are connected to UV lamp holder 23.

[0092] The working principle and beneficial effects of the above technical solution are as follows:

[0093] During the spraying operation, the lifting mechanism is activated to raise the UV lamp holder 23 and completely house it within the receiving groove 22. This solves the problem of paint splattering onto the UV lamp holder 23 during spraying, causing contamination of the UV lamp 24 and preventing it from providing an effective light source. During the drying operation, the lifting mechanism is activated to lower the UV lamp holder 23 to a preset height, aligning the center of the UV lamp holder 2 with the geometric center of the liquor bottle 2. This adapts to liquor bottles 2 of different heights, providing more uniform illumination and improving the curing effect. It also ensures that the curing process is similar at all locations on the liquor bottle 2, facilitating control of the UV curing time.

[0094] Example 6:

[0095] like Figure 3 As shown, based on the above embodiment 5, the lifting mechanism includes:

[0096] The drive gear 25 is rotatably connected to the cavity 26 at the top of the protective cover 21. The gear shaft of the drive gear 25 is connected to the output end of the second motor, which is installed inside the protective cover 21.

[0097] Driven gear 27, multiple driven gears 27 are meshed and connected to the outside of the driving gear 25, and multiple driven gears 27 are evenly arranged in the circumferential direction, and the shaft of the driven gear 27 is rotatably connected to the cavity 26;

[0098] Rope pulley 28 is connected to the shaft of driven gear 27;

[0099] The lifting rope 29 is wound around the rope wheel 28, and the bottom end of the lifting rope 29 passes through the protective cover 21 and is connected to the UV lamp holder 23.

[0100] The working principle and beneficial effects of the above technical solution are as follows:

[0101] When the lifting mechanism is in use, the second motor is started to drive the drive gear 25 to rotate. The drive gear 25 drives multiple driven gears 27 that mesh with it to rotate synchronously, causing multiple rope pulleys 28 to rotate synchronously. This causes the lifting rope 29 to be wound or unwound simultaneously. When the lifting rope 29 is wound so that the unwound part is shortened, it drives the UV lamp holder 23 to rise; when the lifting rope 29 is unwound so that the unwound part is lengthened, it drives the UV lamp holder 23 to fall.

[0102] Example 7:

[0103] like Figures 4-8 As shown, based on the above embodiment 6, the UV lamp holder 23 includes:

[0104] The upper fixing plate 31 and the lower fixing plate 32 have the same structure and are symmetrical. The edges of the upper fixing plate 31 and the lower fixing plate 32 are connected by fixing pieces 30. The bottom end of the upper fixing plate 31 is provided with an annular track, and a toothed ring 33 is connected to the inner side of the annular track. The outer wall of the toothed ring 33 is evenly arranged with locking teeth.

[0105] The UV lamp assembly has its two ends slidably connected to the annular track of the upper fixed plate 31 and the lower fixed plate 32, respectively. The UV lamp assembly is configured as multiple sets and evenly arranged along the circumference of the annular track. Multiple UV lamps 24 are installed in the UV lamp assembly, and the UV lamp assembly does not interfere with the fixed plate 30.

[0106] The third motor 34 is mounted on the top of the upper fixed plate 31. The bottom of the third motor 34 is vertically connected to the drive shaft 35, which is connected to the UV lamp assembly through the rotating disk 36.

[0107] The working principle and beneficial effects of the above technical solution are as follows:

[0108] During the drying process, the spray nozzle 14 is closed to stop spraying; the third motor 34 on the UV lamp holder 23 is started, and the third motor 34 drives the transmission shaft 35 to rotate, and the rotating disk 36 rotates accordingly, thereby driving the UV lamp holder 23 to rotate along the circular track. The upper fixed plate 31, the lower fixed plate 32 and the fixed piece 30 form the skeleton of the UV lamp holder 23. The circular track guides the movement of the UV lamp holder 23, causing it to rotate around the center of the upper fixed plate 31 and the lower fixed plate 32. Through the rotation of the UV lamp 24 and the rotation of the liquor bottle 2, the light can be evenly irradiated on the liquor bottle 2, and the rotation speeds of the two are different. This reduces the problem of inconsistent curing state of two rows of liquor bottles 2 when one UV lamp 24 is damaged during fixed-direction irradiation, facilitates subsequent maintenance and secondary drying of the liquor bottle 2, and thus reduces the defect rate of the liquor bottle 2.

[0109] Example 8:

[0110] like Figures 4-8 As shown, based on the above embodiment 7, the UV lamp assembly includes:

[0111] UV lamp holder 37, on which a UV lamp 24 is installed;

[0112] Rotating sleeve 38 is rotatably mounted between the rotating shafts of the upper and lower UV lamp holders 37, and the rotating sleeve 38 is connected to the rotating disk 36 via connecting rod 39;

[0113] Slider 41 is connected to the other end of the rotating shaft of UV lamp holder 37, and slider 41 is slidably connected in the annular track;

[0114] The transmission gear 42 is connected to the rotating shaft of the UV lamp holder 37, and the transmission gear 42 is meshed with the outer side of the gear ring 33.

[0115] The working principle and beneficial effects of the above technical solution are as follows:

[0116] When the UV lamp assembly is in use, the UV lamp 24 is fixed by the UV lamp holder 37 to keep the UV lamp 24 in a vertical position, so that the light can be emitted onto the outer liquor bottle 2. The rotating disk 36 drives the changing sleeve 38 to rotate through the connecting rod 39, which in turn drives the upper and lower UV lamp holders 37 to rotate around the rotating disk 36. The UV lamp holder 37 drives the slider 41 to move along the circular track. The slider 41 is set to be circular so that it can rotate within the circular track. The UV lamp holder 37 is provided with rotating shafts at both ends. The transmission gears 42 on the rotating shafts mesh with the gear ring 33 to drive the UV lamp holder 37 to rotate on its own axis while rotating around the rotating disk 36. That is, it drives the UV lamp 24 to rotate on its own axis while rotating around the rotating disk 36. This allows the UV lamp 24 to rotate its own direction and point different emission surfaces toward the liquor bottle 2, avoiding the impact of inconsistent light intensity in different directions caused by the UV lamp 24 malfunctioning, and improving the drying and curing effect.

[0117] Example 9:

[0118] like Figures 4-9 As shown, based on the above embodiment 8, the rotating disk 36 includes:

[0119] The transmission chamber 43 and the suction chamber 44 are arranged evenly around the transmission chamber 43 and their positions correspond to the positions of the UV lamp group. The suction chamber 44 is connected to the exhaust gas treatment equipment through a one-way pipe.

[0120] The suction shaft 45 is rotatably disposed in the transmission cavity 43. The top end of the suction shaft 45 is rotatably connected to the transmission shaft 35, and the bottom end is snapped into the lower fixed plate 32.

[0121] The turntable 46 is connected to the suction shaft 45, and the turntable 46 has multiple recessed areas 47 evenly arranged along the circumference.

[0122] Piston 48 is slidably connected in the suction chamber 44. Piston rod 49 is connected to piston 48 and extends into the transmission chamber 43 to abut against the mating turntable 46. A spring is sleeved on piston rod 49 and abuts against the end of piston 48 and suction chamber 44.

[0123] The suction port 51 is located at the bottom of the rotating disk 36 and connected to the suction chamber 44. The suction port 51 is inclined towards the UV lamp group.

[0124] The working principle and beneficial effects of the above technical solution are as follows:

[0125] When the drive shaft 35 drives the rotating disk 36 to rotate, the suction shaft 45 is engaged with the lower fixed plate 32 and does not rotate; the piston rod 49 inside the rotating disk 36 rotates accordingly, causing the piston rod 49 to slide along the edge of the mating rotating disk 46; when the piston rod 49 slides to the recessed area 47 of the mating rotating disk 46, the piston rod 49 moves towards the center of the rotating disk 36 under the action of the spring, and the piston 48 draws the gas near the UV lamp group into the suction chamber 44 through the suction port 51, which is equipped with a one-way air inlet valve; when the piston rod 49 moves out of the recessed area 47 of the mating rotating disk 46, the piston rod 49 is pressed and moves away from the center of the rotating disk 36, and the piston 48 discharges the suction gas through the one-way pipeline to the waste gas treatment equipment for centralized treatment; the spray drying box 11 is equipped with a one-way air inlet valve to introduce external air and ensure internal air pressure balance.

[0126] Through the above structural design, a suction component is set on the rotating disk 36. During UV drying and curing, on the one hand, the high-temperature gas near the UV lamp group is suctioned to control the surface temperature of the UV lamp 24 and extend the service life of the UV lamp 24; on the other hand, the harmful gases generated during painting are suctioned and discharged to the waste gas treatment equipment for centralized treatment, reducing the overflow of harmful gases, realizing the integrated design of drying and waste gas discharge, and improving the environmental protection of the production line.

[0127] Example 10:

[0128] like Figure 4 , Figure 6 As shown, based on the above embodiment 9, the UV lamp holder 23 further includes: a support base 52, the bottom end of the support base 52 is connected to the center of the lower fixing plate 32, the top end is engaged with the suction shaft 45, the upper part of the support base 52 and the outer wall of the support base 52 are evenly provided with multiple protruding ridges 53, and a reflective film 54 is applied to the outer wall of the support base 52 and the protruding ridges 53.

[0129] The working principle and beneficial effects of the above technical solution are as follows:

[0130] A support base 52 is set at the center of the lower fixed plate 32. The support base 52 provides support for the suction shaft 45, ensuring that the suction shaft 45 does not rotate. When the UV lamp 24 is irradiated, the light emitted outward will shine on the liquor bottle 2 to accelerate the curing of the paint. By setting a reflective film 54 on the support base 52, the light emitted inward is reflected by the reflective film 54 and then emitted outward, also shining on the liquor bottle 2. The support base 52 is provided with convex ridges 53 to form an uneven structure, so that the reflected light can be scattered outward and evenly irradiated on the liquor bottle 2.
