Abstract
Description
Technical Field
[0001] This utility model relates to the field of PET bottle processing technology, and more specifically, to an auxiliary device for blowing air at the inlet of a PET bottle air conveying line. Background Technology
[0002] In the PET bottle manufacturing industry, traditional blow molding machine pneumatic conveyor systems typically use mechanical extrusion at the rear end of the bottle to push PET bottles. This conveying mode, which relies on mechanical contact to transmit power, has several insurmountable drawbacks. On the one hand, the significant friction generated between the lower end face of the bottle neck and the slide rail during the extrusion process not only increases energy consumption but also easily leads to scratches and abrasions on the bottle surface, affecting the product's appearance quality. On the other hand, it is difficult to ensure uniform force on the PET bottle during mechanical extrusion, making the bottle prone to deformation and blockage during transport. Once blockage occurs, it not only requires a large amount of manpower for unblocking but also causes production line interruptions, greatly reducing production efficiency. Therefore, improvements are needed. Utility Model Content

[0009] As a preferred embodiment of the present invention, the filtration mechanism includes a filter cylinder, a top cover that is movably fitted onto the filter cylinder, a limiting block that is fixedly installed inside both the filter cylinder and the top cover, and a filter plate that is provided inside the limiting block.
[0010] As a preferred embodiment of this utility model, screws are fitted inside the outer surfaces of the filter cartridge and the top cover, and nuts are threaded onto the outer surfaces of the screws, with the nuts abutting against the outer surface of the top cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This PET bottle air conveying line inlet blowing auxiliary device, due to the design of the blowing mechanism and the pulse mechanism, can be conveniently switched between continuous blowing and pulse blowing through valve control. When the continuous blowing mode is used, it can provide stable air force assistance for PET bottles to enter the air conveying line, effectively reducing the friction between the bottles and the slide rail, and ensuring a smooth and stable conveying process. When switching to the pulse blowing mode, the intermittently generated strong thrust can powerfully push the PET bottles. Even in the face of uneven force and difficulty in pushing, it can ensure that the bottles enter the air conveying line quickly and stably. The two modes complement each other, significantly improving the conveying efficiency and stability of PET bottles at the air conveying line inlet.
[0014] 2. This PET bottle air conveying line inlet blowing auxiliary device, due to the design of the filtration mechanism, effectively improves the practicality and reliability of the device. When the airflow generated by the fan enters the device, dust and impurities are effectively intercepted by the filter plate, preventing them from entering the PET bottle with the airflow and preventing contamination of the clean environment inside the bottle. This ensures the product quality of the PET bottle from the source. At the same time, the filter plate is firmly fixed by the limiting block, ensuring that it can maintain a stable filtration effect under the impact of airflow. When the filter plate becomes clogged after a period of use, the operator only needs to unscrew the nuts and pull out the screws to release the fixation between the filter cartridge and the top cover, easily remove the top cover, and conveniently clean or replace the filter plate.

[0017] 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.
[0018] like Figures 1 to 6 As shown, this utility model provides an air blowing auxiliary device for the inlet of a PET bottle air conveying line, comprising: There are two guide plates 1, and a PET bottle 2 is slidably connected between the two guide plates 1. An air duct 3 is fixedly installed at the top of the two guide plates 1. An air blowing mechanism is set at the top of the air duct 3. The air blowing mechanism is composed of a fixed plate 4 and a blower 5. A pulse mechanism and a filter mechanism are respectively set on the air blowing mechanism. The pulse mechanism is composed of a pressure accumulator 12 and a support plate 13. The filter mechanism is composed of a filter cartridge 25 and a top cover 26. A drive mechanism is set on the pulse mechanism. The drive mechanism is composed of a motor 14 and a rotating shaft 15.
[0019] Two guide plates 1 provide sliding guide channels for PET bottles 2, ensuring that PET bottles 2 maintain a stable conveying path before entering the air conveying line duct 3 and avoiding deviation; the fixing plate 4 in the blowing mechanism is used to fix the blower 5 components, providing a stable installation base for the blowing function; the pulse mechanism can generate intermittent strong thrust to assist the conveying of PET bottles 2; the filtration mechanism purifies the air entering the device to prevent dust and impurities from contaminating PET bottles 2; the drive mechanism provides power to the pulse mechanism, driving the relevant components to move to achieve the pulse effect.
[0020] The blowing mechanism includes a fixed plate 4, the bottom of which is fixedly connected to the top of the air duct 3. A fan 5 is fixedly installed on the outer surface of the fixed plate 4. An air inlet pipe 6 is fixedly sleeved inside the fan 5. The outer surface of the air inlet pipe 6 is fixedly sleeved inside the fixed plate 4. A first air supply pipe 7 and a second air supply pipe 8 are fixedly sleeved inside the right end of the air inlet pipe 6, respectively. Valves are provided on both the first air supply pipe 7 and the second air supply pipe 8. A connecting pipe 9 is fixedly sleeved at the end of the first air supply pipe 7 and the second air supply pipe 8 away from the air inlet pipe 6. An air outlet pipe 10 is fixedly sleeved inside the end of the connecting pipe 9 away from the first air supply pipe 7 and the second air supply pipe 8. A nozzle 11 is fixedly sleeved at the bottom end of the air outlet pipe 10.
[0021] The fixed plate 4 connects the air duct 3 and the fan 5 to ensure the stable operation of the fan 5; the fan 5 draws in air and delivers it through the air inlet pipe 6; the valves on the first air supply pipe 7 and the second air supply pipe 8 are used to switch the blowing mode. When the valve of the first air supply pipe 7 is opened, air is continuously blown out from the nozzle 11 through the connecting pipe 9 and the air outlet pipe 10, providing stable wind power to assist the PET bottle 2 in entering the air delivery line; when the valve of the second air supply pipe 8 is opened, air enters the pulse mechanism to realize pulse blowing.
[0022] Among them, the outer surface of the connecting pipe 9 is fixedly sleeved with a support plate 13, and the outer surface of the support plate 13 is fixedly connected to the outer surface of the air duct 3.
[0023] The support plate 13 securely installs the connecting pipe 9 on the air duct 3, enhancing the stability of the connection between the blowing mechanism and the air duct 3, preventing the connecting pipe 9 from loosening or shifting due to vibration during the air transmission process, and ensuring the stability and reliability of the air transmission.
[0024] The pulse mechanism includes a pressure accumulator 12, a slide groove 19 is fixedly installed inside the pressure accumulator 12, a moving block 18 is slidably connected inside the slide groove 19, a round rod 20 is fixedly installed on the outer surface of the moving block 18, a piston 21 is fixedly installed at the left end of the round rod 20, a short pipe 22 is slidably connected to the outer surface of the piston 21, an air outlet 23 is opened on the outer surface of the short pipe 22, and a partition 24 is fixedly sleeved on the outer surface of the short pipe 22, and the partition 24 is fixedly sleeved with the inside of the pressure accumulator 12.
[0025] The accumulator chamber 12 is used to store air and create a high-pressure environment; the slide 19 provides a sliding track for the moving block 18, enabling the moving block 18 to move stably left and right under the action of the drive mechanism; the round rod 20 connects the moving block 18 and the piston 21 to transmit motion force; the piston 21 moves in the short pipe 22, controlling the air flow by blocking and opening the short pipe 22, realizing the alternation of pressure storage and jet ejection; the partition 24 divides the accumulator chamber 12 into left and right spaces to ensure that the air forms a pulse effect under a specific path.
[0026] The drive mechanism includes a motor 14, which is fixedly connected to the outer surface of the accumulator chamber 12. A rotating shaft 15 is fixedly sleeved at the output end of the motor 14. A rotating block 16 is fixedly sleeved on the outer surface of the rotating shaft 15. An extrusion shaft 17 is fixedly installed inside the rotating block 16. The outer surface of the extrusion shaft 17 is slidably connected to the inside of the moving block 18.
[0027] The motor 14 serves as the power source, converting the rotational motion into the linear reciprocating motion of the moving block 18 through the rotating shaft 15, the rotating block 16, and the extrusion shaft 17. During the rotation, the extrusion shaft 17 extrudes the moving block 18, driving the piston 21 to move left and right within the short tube 22, thereby controlling the air pressure storage and release within the pressure storage chamber 12 to achieve the pulse blowing effect.
[0028] The filtration mechanism includes a filter cartridge 25, a top cover 26 that is movably attached to the filter cartridge 25, and a limiting block 27 that is fixedly installed inside both the filter cartridge 25 and the top cover 26. A filter plate 28 is provided inside the limiting block 27.
[0029] The filter cartridge 25 and the top cover 26 form a closed filtration space. The limiting block 27 positions and fixes the filter plate 28 to ensure that the filter plate 28 remains stable during the filtration process. The filter plate 28 can effectively intercept dust and impurities in the air and prevent them from entering the interior of the PET bottle 2, thus ensuring the cleanliness of the PET bottle 2.
[0030] Screws 29 are fitted inside the outer surfaces of the filter cartridge 25 and the top cover 26. Nuts 30 are threaded onto the outer surfaces of the screws 29 and abut against the outer surface of the top cover 26.
[0031] Screw 29 and nut 30 are used to fix the filter cartridge 25 and the top cover 26, so that the filtration mechanism forms a stable whole. When it is necessary to clean or replace the filter plate 28, the nut 30 can be unscrewed and the screw 29 can be pulled out to achieve quick maintenance of the filter plate 28.
[0032] The bottom end of the guide plate 1 is fixedly installed with a base frame 31, and a reinforcing rod 32 is provided on the base frame 31.
[0033] The base frame 31 provides a supporting foundation for the entire device, and the reinforcing rod 32 can enhance the structural strength and stability of the base frame 31, ensuring that the device remains stable during operation.
[0034] A connecting block 33 is fixedly installed on the outer surface of the base frame 31, and a guide rod 34 is fixedly installed inside the end of the connecting block 33 away from the base frame 31. The guide rod 34 is in contact with the outer surface of the PET bottle 2.
[0035] The connecting block 33 is used to fix the guide rod 34. The guide rod 34 contacts the outer surface of the PET bottle 2. The auxiliary guide plate 1 guides the PET bottle 2, further improving the stability of the PET bottle 2 during the conveying process, preventing the PET bottle 2 from tilting or deviating during the sliding process, and ensuring that it smoothly enters the air conveying line.
[0036] Working principle and usage process of this utility model: In actual operation, the PET bottle 2 is first accurately placed between the two guide plates 1, while the guide rod 34 is tightly fitted to the outer surface of the PET bottle 2, effectively enhancing the stability of the PET bottle 2 during transportation. After the equipment is started, the blower 5 starts running, introducing outside air into the air inlet pipe 6. At this time, the blowing mode can be flexibly switched according to the actual transportation needs of the PET bottle 2.
[0037] When the continuous blowing mode is selected, the operator opens the valve of the first air supply pipe 7 and closes the valve of the second air supply pipe 8. The airflow generated by the blower 5 will pass through the first air supply pipe 7, the connecting pipe 9, and the air outlet pipe 10 in sequence, and finally be blown out stably from the nozzle 11. This continuous and stable airflow will blow on the mouth of the PET bottle 2. Under the action of the wind, the PET bottle 2 obtains a continuous and stable thrust, which can actively and smoothly enter the air duct 3, effectively reducing the friction between the bottle and the slide rail and ensuring the smoothness of the conveying process.
[0038] If the pulse blowing mode is selected, the valve of the first air supply pipe 7 must be opened and the valve of the second air supply pipe 8 must be closed. At this time, the air blown out by the blower 5 will first enter the left space of the accumulator 12. Due to the blockage of the short pipe 22 by the piston 21, the air continuously accumulates, causing the pressure in the left space of the accumulator 12 to gradually increase. At the same time, the operator starts the motor 14, which drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the rotating block 16 and the extrusion shaft 17 to rotate together. During the rotation, the extrusion shaft 17 continuously extrudes the interior of the moving block 18, causing the moving block 18 to drive the piston 21 to reciprocate left and right in the short pipe 22. When the piston 21 moves to the right to a specific position and releases the blockage of the short pipe 22, the high-pressure air in the left space of the accumulator 12 will quickly rush into the right space through the air outlet 23. Through connecting pipe 9 and air outlet pipe 10, the air is instantly ejected from nozzle 11, forming a strong pulse thrust. Even if the PET bottles 2 are stacked misaligned or have uneven force, they can still smoothly enter the air duct 3 with this powerful instantaneous thrust. When piston 21 moves to the left, it will block short pipe 22 again, causing the space on the left side of accumulator 12 to enter the air accumulator stage again. As air is continuously injected, the pressure inside the chamber gradually increases, accumulating energy for the next pulse jet. This cycle continues, and the reciprocating motion of piston 21 continuously realizes the alternation of accumulator and jet. Even if the PET bottles 2 are stacked misaligned or have uneven force, they can still smoothly enter the air duct 3 with this continuous and powerful pulse thrust.
[0039] It is worth mentioning that during the entire blowing process, the air entering the air inlet pipe 6 flows through the filtration mechanism composed of the filter cartridge 25, top cover 26, and filter plate 28. The filter plate 28 can effectively intercept dust and impurities in the air, preventing them from entering the PET bottle 2 with the airflow, thereby ensuring a clean environment inside the PET bottle 2. If the filter plate 28 becomes clogged after a period of use, affecting the filtration effect, the operator only needs to unscrew the nut 30 and pull out the screw 29 to disconnect the fixed connection between the filter cartridge 25 and the top cover 26, easily remove the top cover 26, and then clean or replace the filter plate 28. The entire maintenance process is simple and convenient, effectively reducing downtime caused by filter component clogging and ensuring continuous and efficient operation of the equipment.
