Description
Technical Field
[0001] This utility model belongs to the field of high-barrier bottle inner film spraying technology, specifically a high-barrier bottle inner film spraying device. Background Technology
[0002] The high-barrier bottle inner membrane spraying device is used to uniformly spray a layer of high-barrier coating on the inner wall surface of a high-barrier bottle. Its purpose is to enhance the bottle's ability to block substances such as oxygen and water vapor, and extend the shelf life of the product inside the bottle.
[0003] The specific design and structure of internal expansion tooling for pipe welding may vary depending on the manufacturer and application requirements, but generally they include the following key components: spraying mechanism and fixing device, among which the spraying mechanism is the core part of the device, usually including spray gun, paint supply system and spraying control device. There are various types of spray guns, such as air spray guns and electrostatic spray guns, which can spray high-barrier paint evenly on the inner surface of the bottle in the form of mist. The fixing device is used to accurately fix the position of the bottle to ensure that the spray gun can accurately spray the inner surface of the bottle. These devices can be adjusted according to the shape and size of the bottle to accommodate different types of high-barrier bottles.
[0004] The cleanliness of the inner surface of a high-barrier bottle has a crucial impact on the adhesion and quality of the coating. If dust or impurities are present inside the bottle, the coating will not bond tightly to the inner wall, leading to quality problems such as coating peeling and blistering. Existing high-barrier bottle inner film spraying devices lack an internal cleaning structure. During storage, the coating may experience sedimentation and stratification, resulting in uneven coating composition. This leads to inconsistent film thickness and unstable performance, affecting the quality and effectiveness of the high-barrier bottle inner film. Furthermore, the spraying tube cannot rotate flexibly and relies solely on a fixed angle for spraying, resulting in some areas of the inner surface being over-covered while others are under-covered, causing uneven spraying. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a high-barrier bottle inner membrane spraying device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a high-barrier bottle inner film spraying device, including a transmission frame, a support frame on the transmission frame, an mounting plate on the support frame, an adjusting cylinder on the mounting plate, a lifting plate at the output end of the adjusting cylinder, a dust removal pipe rotatably mounted on the lifting plate, a driven gear on the dust removal pipe, a limit plate below the driven gear, and several dust removal brushes and dust removal holes below the limit plate; a dust removal bucket on the mounting plate, a dust removal bag inside the dust removal bucket, a sealing cap hinged to the dust removal bucket around the dust removal bag, a filter plate on the side of the dust removal bag, a dust removal fan on the side of the filter plate, a dust removal motor on the side of the dust removal fan, the output end of the dust removal motor being fixedly mounted to the rotating shaft of the dust removal fan, an exhaust pipe at the bottom of the dust removal bucket, and a dust removal hose at the top of the dust removal bucket, the other end of the dust removal hose being rotatably mounted on the dust removal pipe via the lifting plate.
[0007] A spraying pipe is rotatably mounted on the lifting plate, and a second driven gear is mounted on the spraying pipe. A limit plate is also mounted below the second driven gear, and several spray nozzles are mounted below the limit plate. A storage tank is mounted on the mounting plate, and a feed pipe is mounted on the storage tank. A stirring motor is mounted on the storage tank, and an auger shaft is rotatably mounted inside the storage tank. The output end of the stirring motor is fixedly connected to the auger shaft, and auger blades are mounted on the auger shaft. A liquid pump is mounted on the side of the storage tank, and the liquid pump is connected to the storage tank through a liquid extraction pipe and to the spraying pipe through a liquid delivery pipe. The stirring motor inside the storage tank drives the auger shaft and auger blades to rotate, thoroughly stirring the paint to ensure uniformity and providing a basic guarantee for spraying quality. At the same time, the adjusting motor, through the meshing of the transmission gear and the driven gear, realizes the rotation of the spraying pipe, ensuring that the paint can evenly cover the inner surface of the bottle, improving the accuracy and consistency of spraying.
[0008] A transmission roller is rotatably mounted on the transmission frame. A motor bracket is provided on the side of the transmission frame. A transmission motor is mounted on the motor bracket. The output end of the transmission motor is fixedly connected to the transmission roller. A driven roller is rotatably mounted on the transmission frame. Both the transmission roller and the driven roller are provided with pulleys. A transmission belt is fitted on the two pulleys. Several fixed grooves are opened on the transmission belt.
[0009] An adjusting motor is installed on the lifting plate, and a transmission gear is provided at the output end of the adjusting motor. The transmission gear meshes with the first driven gear and the second driven gear, so that the rotation angle and speed of the dust removal pipe and the spraying pipe can be flexibly adjusted according to actual needs to adapt to different dust removal and spraying requirements, thereby improving the operational flexibility and adaptability of the device.
[0010] The transmission frame is equipped with four support legs at its bottom. Two fixing slots are located directly below the dust removal pipe and the spraying pipe, respectively. The design of the fixing slots ensures the accurate positioning of the bottle during the conveying process. The fact that the two fixing slots are located directly below the dust removal pipe and the spraying pipe ensures that the bottle is accurately positioned when passing through the dust removal and spraying areas, so that the dust removal and spraying operations can be carried out smoothly, and improves the stability and reliability of the entire spraying process.
[0011] The dust collector motor, stirring motor, infusion pump, drive motor, and regulating motor are all electrically connected to an external power source. After these motors are electrically connected to an external power source, they can be uniformly managed and controlled through an electrical control system.
[0012] The advantages of this invention are as follows: the lifting plate can be flexibly controlled by adjusting the cylinder, so that the dust removal pipe can be accurately inserted into high-barrier bottles of different specifications. The dust removal brush on the dust removal pipe, in conjunction with the rotation function, can clean the inner wall of the bottle from all directions. Then, the dust removal motor drives the dust removal fan to generate suction, which sucks the dust into the dust removal bucket through the dust removal hole and dust removal hose. After being filtered by the dust removal bag and filter plate, efficient dust removal is achieved, providing a clean inner surface for subsequent spraying work and ensuring the adhesion and quality of the coating.
[0013] The stirring motor inside the storage tank drives the auger shaft and auger blades to rotate, thoroughly stirring the coating to ensure uniformity and provide a basic guarantee for spraying quality. At the same time, the regulating motor, through the meshing of the transmission gear and the driven gear, realizes the rotation of the spraying pipe, ensuring that the coating can evenly cover the inner surface of the bottle, improving the accuracy and consistency of spraying.

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 scope of protection of the present utility model.
[0017] Please see Figure 1-5 As shown, a high-barrier bottle inner film spraying device includes a transmission frame 1, a support frame 9 on the transmission frame 1, a mounting plate 10 on the support frame 9, an adjusting cylinder 11 on the mounting plate 10, a lifting plate 12 at the output end of the adjusting cylinder 11, a dust removal pipe 14 rotatably mounted on the lifting plate 12, a driven gear 15 on the dust removal pipe 14, a limit plate 16 below the driven gear 15, and several dust removal brushes 17 and dust removal holes 18 below the limit plate 16. A dust collection bin 24 is provided on the mounting plate 10. A dust collection bag 27 is provided inside the dust collection bin 24. A sealing cover 26 is hinged to the dust collection bin 24 around the dust collection bag 27. A filter plate 28 is provided on the side of the dust collection bag 27. A dust collection fan 29 is provided on the side of the filter plate 28. A dust collection motor 30 is provided on the side of the dust collection fan 29. The output end of the dust collection motor 30 is fixedly connected to the rotating shaft of the dust collection fan 29. An exhaust pipe 31 is provided at the bottom of the dust collection bin 24. A dust collection hose 25 is provided at the top of the dust collection bin 24. The other end of the dust collection hose 25 is rotatably mounted on the dust collection pipe 14 via a lifting plate 12.
[0018] During operation, in order to clean the inner wall of the bottle, when the bottle moves below the dust removal pipe 14, the regulating cylinder 11 is activated, pushing the lifting plate 12 down so that the dust removal pipe 14 is inserted into the bottle. At this time, the dust removal motor 30 runs, driving the dust removal fan 29 to rotate. Under the action of the dust removal fan 29, air enters from the dust removal hole 18 on the dust removal pipe 14, carrying the dust inside the bottle through the dust removal pipe 14 and the dust removal hose 25 into the dust removal bin 24. Inside the dust removal bin 24, the dust is filtered and intercepted by the dust removal bag 27, and the purified air is discharged from the exhaust pipe 31. At the same time, the regulating motor 22 works, and the transmission gear 23 at its output end meshes with the first driven gear 15, driving the dust removal pipe 14 to rotate, so that the dust removal brush 17 can clean the inner wall of the bottle from all directions, improving the dust removal effect.
[0019] A spray pipe 19 is rotatably mounted on the lifting plate 12. A second driven gear 20 is mounted on the spray pipe 19. A limit plate 16 is also mounted below the second driven gear 20. Several nozzles 21 are mounted below the limit plate 16. A storage tank 32 is mounted on the mounting plate 10. A feed pipe 36 is mounted on the storage tank 32. A stirring motor 33 is mounted on the storage tank 32. An auger shaft 34 is rotatably mounted inside the storage tank 32. The output end of the stirring motor 33 is fixedly connected to the auger shaft 34. An auger blade 35 is mounted on the auger shaft 34. A liquid pump 37 is mounted on the side of the storage tank 32. The liquid pump 37 is connected to the storage tank 32 through a liquid extraction pipe and to the spray pipe 19 through a liquid delivery pipe.
[0020] A transmission roller 3 is rotatably mounted on the transmission frame 1. A motor bracket 4 is provided on the side of the transmission frame 1. A transmission motor 5 is mounted on the motor bracket 4. The output end of the transmission motor 5 is fixedly connected to the transmission roller 3. A driven roller 2 is rotatably mounted on the transmission frame 1. Both the transmission roller 3 and the driven roller 2 are provided with pulleys. A transmission belt 6 is sleeved on the two pulleys. Several fixed grooves 7 are opened on the transmission belt 6.
[0021] During operation, in order to spray the bottle, before spraying, the feed pipe 36 feeds the high-barrier coating into the storage tank 32. The stirring motor 33 starts, driving the auger shaft 34 and auger blades 35 to rotate, stirring the coating in the storage tank 32 to ensure uniform coating. When the bottle has finished dust removal and moves to the bottom of the spray pipe 19, the next new bottle also moves to the bottom of the dust removal pipe 14. The adjusting cylinder 11 is activated again, causing the dust removal pipe 14 to be inserted into the new bottle to repeat the above cleaning work, cleaning the inner wall of the new bottle. The spray pipe 19 is inserted into the cleaned bottle, and the infusion pump 37 starts, drawing the coating in the storage tank 32 out through the extraction pipe and transporting it to the spray pipe 19 through the infusion pipe. It is then sprayed out by the nozzle 21, evenly sprayed onto the inner film of the bottle. The transmission gear 23 of the adjusting motor 22 meshes with the second driven gear 20, driving the spray pipe 19 to rotate, ensuring that the coating evenly covers the inner surface of the bottle.
[0022] An adjusting motor 22 is installed on the lifting plate 12. The output end of the adjusting motor 22 is provided with a transmission gear 23, which meshes with the first driven gear 15 and the second driven gear 20. The bottom end of the transmission frame 1 is provided with four support legs 8. Two fixing slots 7 are located directly below the dust removal pipe 14 and the spraying pipe 19, respectively. The dust removal motor 30, the stirring motor 33, the infusion pump 37, the transmission motor 5 and the adjusting motor 22 are all electrically connected to an external power source.
[0023] During operation, the drive motor 5 is powered on to transport the bottles, and its output drives the drive roller 3 to rotate. Since the drive roller 3 and the driven roller 2 are connected to the drive belt 6 through pulleys, the drive belt 6 moves accordingly. The high-barrier bottles placed on the fixed groove 7 of the drive belt 6 will pass through the dust removal and spraying areas in sequence as the drive belt 6 moves.
[0024] Working principle: In order to transport the bottle, the drive motor 5 is powered on and runs, and its output end drives the drive roller 3 to rotate. Since the drive roller 3 and the driven roller 2 are connected to the drive belt 6 through the pulley, the drive belt 6 moves accordingly. The high-barrier bottle placed on the fixed groove 7 of the drive belt 6 will pass through the dust removal and spraying areas in sequence as the drive belt 6 moves.
[0025] To clean the inner wall of the bottle, when the bottle is moved below the dust removal pipe 14, the regulating cylinder 11 is activated, pushing the lifting plate 12 down so that the dust removal pipe 14 is inserted into the bottle. At this time, the dust removal motor 30 runs, driving the dust removal fan 29 to rotate. Air enters through the dust removal hole 18 on the dust removal pipe 14 under the action of the dust removal fan 29, carrying the dust in the bottle through the dust removal pipe 14 and the dust removal hose 25 into the dust removal bin 24. Inside the dust removal bin 24, the dust is filtered and intercepted by the dust removal bag 27, and the purified air is discharged from the exhaust pipe 31. At the same time, the regulating motor 22 works, and the transmission gear 23 at its output end meshes with the first driven gear 15, driving the dust removal pipe 14 to rotate, so that the dust removal brush 17 can clean the inner wall of the bottle from all directions, improving the dust removal effect.
[0026] Before spraying, the high-barrier coating is fed into the storage tank 32 through the feed pipe 36. The stirring motor 33 is started, driving the auger shaft 34 and auger blades 35 to rotate and stir the coating in the storage tank 32 to ensure uniform coating. When the bottle has been dusted and moved under the spray pipe 19, the next new bottle is also moved under the dust removal pipe 14. The adjusting cylinder 11 is activated again, causing the dust removal pipe 14 to be inserted into the new bottle and repeat the above cleaning work to clean the inner wall of the new bottle. The spray pipe 19 is inserted into the cleaned bottle, and the infusion pump 37 is started to draw out the coating in the storage tank 32 through the extraction pipe and deliver it to the spray pipe 19 through the infusion pipe. It is then sprayed out by the nozzle 21 and evenly sprayed onto the inner film of the bottle. The transmission gear 23 of the adjusting motor 22 meshes with the second driven gear 20 to drive the spray pipe 19 to rotate, ensuring that the coating evenly covers the inner surface of the bottle.
