Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle production and processing, specifically to a far-infrared drying device for plastic bottle production. Background Technology

[0002] In plastic bottle production, molded plastic bottles contain moisture. If not dried promptly, this moisture can affect their strength and transparency, and may even lead to mold growth. Traditional hot air drying relies on convection heat transfer, which is inefficient, time-consuming, and energy-intensive. Furthermore, hot air can cause uneven temperature distribution, resulting in inconsistent heating of different parts of the bottle and inconsistent drying effects. Some parts may not be completely dry, while others may deform due to overheating. Far-infrared drying technology is a new and highly efficient method. Its wavelength ranges from 5.6 to 1000 micrometers, within which the natural vibrational frequencies of most molecules fall. When far-infrared rays irradiate a plastic bottle, if the frequency matches the natural frequency of the bottle's molecules, resonance occurs, intensifying molecular motion and causing a rapid and uniform temperature increase both inside and outside the bottle, achieving efficient drying. Compared to traditional methods, it offers higher thermal efficiency (60-70%), faster drying, and more uniform drying, avoiding quality problems caused by uneven heating. However, current far-infrared drying equipment used in plastic bottle production still needs optimization in terms of structural design, radiation source layout, and intelligent control to meet the demands of large-scale, high-quality production.

[0003] Application number CN202223395873.6 discloses a drying device for plastic bottle production, which relates to the field of plastic bottle production equipment. It includes a drying device body and a drying structure. The device is characterized in that: a support leg is fixed at the bottom of the drying device body, and a conveyor belt is installed on the inner side of the drying device body. A drying box is provided above the drying device body. This invention, through the design of a drying hood, an air outlet rod, and a folding cover, allows the drying chamber to move downwards. The lower drying hood moves to the outside of the plastic bottle body, the air outlet rod is inserted into the inside of the plastic bottle body, and the folding cover at the bottom of the drying hood moves down to fit against the top of the conveyor belt, blocking the gap between the conveyor belt and the drying hood to prevent heat loss. High-temperature airflow enters the interior of the drying hood through the air inlet slot, then flows into the air chamber and the air outlet rod, and exits through the air outlet slot, drying both the outer wall and the interior of the plastic bottle body. This bidirectional drying improves drying efficiency and reduces drying time. However, a drawback is that the device relies solely on a single fan for drying, resulting in low efficiency during processing and production. Utility Model Content

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.

[0025] Please see Figures 1-4 As shown, this utility model is a far-infrared drying device for plastic bottle production, including a drying box assembly 1. A braking assembly 2 is slidably installed on one side of the top of the drying box assembly 1, and a hot drying assembly 5 is fixedly installed on one side of the outer wall of the drying box assembly 1. At the same time, lamp drying assemblies 4 are fixedly installed on both sides of the inner wall of the drying box assembly 1. A moving stirring assembly 3 is drivenly installed on the bottom side of the braking assembly 2, and the moving stirring assembly 3 is limited and installed on both sides of the top of the drying box assembly 1.

[0026] The lamp drying assembly 4 includes a limiting support plate 401, which is fixedly installed at both ends of the inner walls on both sides of the working box 101, and an infrared lamp tube 402 is fixedly installed between the two limiting support plates 401.

[0027] By adding a lamp drying component 4 to the hot drying component in the device, a dual drying effect can be achieved when using the device, thereby improving the efficiency of the device in the processing process.

[0028] The drying oven assembly 1 includes a working chamber 101. Protective support plates 102 are fixedly installed on the top of both sides of the working chamber 101, and a ventilation groove 103 is fixedly installed on the bottom of the working chamber 101. At the same time, a hot air duct 104 is fixedly installed on one side of the working chamber 101. The ventilation groove 103 is set as a perforated plate. The perforated plate of the ventilation groove 103 of the drying oven assembly 1 allows air circulation inside and outside the working chamber 101, which helps to remove moisture. The protective support plates 102 play a protective and limiting role for the moving stirring assembly 3 and the braking assembly 2.

[0029] The braking assembly 2 includes a movable bracket 201. The bottom side of the movable bracket 201 is slidably mounted on the outside of the protective support plate 102 on one side via a sliding clamping wheel 202. At the same time, a brake motor 203 is fixedly mounted on the top of the movable bracket 201. A transmission device 204 is fixedly mounted on the end of the brake motor 203. A transmission rod 205 is fixedly mounted in the middle of the transmission end of the transmission device 204. When the brake motor 203 of the braking assembly 2 is started, the brake motor 203 drives the transmission rod 205 to rotate through the transmission device 204. The movable gears 301 at both ends of the transmission rod 205 roll on the limiting rack 302.

[0030] The movable stirring assembly 3 includes a movable gear 301 and a connecting hinge 303. The movable gear 301 is fixedly installed at both ends of the transmission rod 205 and is located on the top side of the limiting rack 302. The movable gear 301 and the limiting rack 302 mesh with each other. The limiting rack 302 is fixedly installed on the top of both sides of the working box 101 and is correspondingly located inside the protective support plate 102. The connecting hinge 303 is fixedly installed on the outer wall of the transmission rod 205 and a soft silicone pusher 304 is installed on the outer side of the connecting hinge 303.

[0031] The soft silicone pusher 304 is made of soft silicone. The brake motor 203 of the braking assembly 2 drives the transmission rod 205 to rotate through the transmission device 204, which in turn causes the moving gear 301 of the moving stirring assembly 3 to roll on the limiting rack 302, thereby moving the soft silicone pusher 304 to stir the plastic bottle.

[0032] The hot drying assembly 5 includes a mounting bracket 501, which is fixedly installed at the outer end of the hot air duct 104. A braking host 502 is fixedly installed on the top of the mounting bracket 501, and a hot air rotor 504 is correspondingly installed on the bottom side of the braking host 502. The hot air rotor 504 is fixedly installed inside the mounting bracket 501 by a positioning post 503. In the hot drying assembly 5, the braking host 502 drives the hot air rotor 504 to work, and the generated hot air enters the working chamber 101 through the hot air duct 104, working in synergy with the heat of the lamp drying assembly 4.

[0033] The far-infrared drying equipment for plastic bottle production combines the far-infrared radiation heat generated by the lamp drying component (4) with the hot air transported by the heat drying component (5) to form a dual heating source, which efficiently dries the plastic bottles in the working chamber (101). At the same time, the moving stirring component (3) is driven by the braking component (2) to stir the plastic bottles during the drying process, so that the plastic bottles are heated evenly and the drying efficiency is improved. In the lamp drying component (4), the limiting support plates (401) fixed at both ends of the inner walls on both sides of the working chamber (101) play a supporting and fixing role for the infrared lamp tube (402). After the infrared lamp tube (402) is powered on, it generates far-infrared rays, which directly radiate to the surface of the plastic bottle to achieve heating and drying.

[0034] In the hot drying assembly 5, the brake host 502 drives the hot air rotor 504 to work, and the generated hot air enters the working chamber 101 through the hot air duct 104, working in conjunction with the heat from the lamp drying assembly 4. The brake motor 203 of the brake assembly 2 drives the transmission rod 205 to rotate through the transmission device 204, which in turn causes the moving gear 301 of the moving stirring assembly 3 to roll on the limiting rack 302, driving the soft silicone pusher 304 to move and stir the plastic bottles. The ventilation bottom groove 103 of the drying chamber assembly 1 is a perforated plate, which can realize the air circulation inside and outside the working chamber 101, which helps to remove moisture. The protective support plate 102 provides protection and limit the moving stirring assembly 3 and the brake assembly 2. In the working process, the plastic bottles to be dried are placed inside the working chamber 101, ensuring that all parts of the equipment are connected normally, checking whether the infrared lamp 402, brake motor 203, brake host 502, etc. are working normally, and simultaneously starting the lamp drying assembly 4 and the hot drying assembly 5. The infrared lamp 402 of the lamp drying assembly 4 is energized to generate far-infrared rays, which radiate and heat the plastic bottles inside the working chamber 101. The brake motor 502 of the heat drying assembly 5 is started, driving the hot air fan 504 to run. The generated hot air enters the working chamber 101 through the hot air duct 104, causing the temperature inside the chamber to gradually rise. The brake motor 203 of the brake assembly 2 is started. The brake motor 203 drives the transmission rod 205 to rotate through the transmission device 204. The moving gears 301 at both ends of the transmission rod 205 are in contact with the limit rack. The plastic bottles roll on the 302. Because the moving gear 301 meshes with the limiting rack 302, and the moving stirring assembly 3 is limited and installed on both sides of the top of the drying chamber assembly 1, the connecting hinge 303 drives the soft silicone pusher 304 to reciprocate within the working chamber 101. During this movement, the soft silicone pusher 304 stirs the plastic bottles, causing them to continuously tumble within the working chamber 101, ensuring that each bottle is evenly heated by the radiation from the infrared lamp 402 and the hot air delivered by the heating assembly 5. During operation, moisture inside the chamber is discharged through the ventilation duct 103, maintaining a dry environment. Once the plastic bottles are dried to the required temperature, the lamp-drying assembly 4 and the heating assembly 5 are turned off to stop heating. After the temperature inside the working chamber 101 drops to a suitable level, the braking assembly 2 is turned off, and the moving stirring assembly 3 stops working. Finally, the dried plastic bottles are removed from the working chamber 101.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
