Description

Technical Field

[0001] This utility model relates to the field of ultraviolet sterilization furnace technology, specifically a sealing mechanism for an ultraviolet sterilization furnace. Background Technology

[0002] An ultraviolet (UV) sterilization oven is a device that uses ultraviolet radiation for disinfection and sterilization. It is widely used in medical, laboratory, and food processing fields. Its working principle involves irradiating target objects or airborne microorganisms with ultraviolet light of a specific wavelength (usually 254 nanometers), destroying their DNA or RNA, thereby effectively inhibiting or killing bacteria, viruses, and other pathogens. UV sterilization ovens are typically designed as enclosed spaces to ensure that ultraviolet light can fully irradiate all surfaces of the object being treated for optimal sterilization. Furthermore, this equipment is easy to operate, requires no chemical agents, and avoids the potential hazards of chemical residues, thus being considered an environmentally friendly and safe disinfection method. With technological advancements, modern UV sterilization ovens may also be equipped with intelligent control systems that can monitor sterilization effects and equipment status in real time, improving the reliability and efficiency of sterilization.

[0003] Based on existing ultraviolet sterilization ovens, it was found that the shielding performance of ultraviolet sterilization ovens used on conveyor production lines is poor, and ultraviolet rays can leak out. Although ultraviolet rays can disinfect and sterilize, their impact on human beings is extremely negative, which may cause skin damage, eye damage and damage to the human immune system. In addition, on the conveyor belt of the ultraviolet sterilization oven, objects are easily blocked by lead curtains and cannot be transported, which affects the continuous sterilization work.

[0004] Based on this, the present invention designs a sealing mechanism for an ultraviolet sterilization oven to solve the above problems. Utility Model Content

[0027] 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.

[0028] Please see Figures 1-8In this embodiment of the present invention, a sealing mechanism for an ultraviolet sterilization oven includes a conveyor belt 1 with an ultraviolet sterilization chamber 2 on it. A shielding mechanism 3 is provided on both the left and right sides of the ultraviolet sterilization chamber 2. A material feeding mechanism 4 is provided inside the shielding mechanism 3. The shielding mechanism 3 includes a second shielding chamber 303, a second nylon curtain 304, and a second chamber door 306. The second shielding chamber 303 is fixedly installed at the left end of the ultraviolet sterilization chamber 2, and the second nylon curtain 304 is installed at the left end of the second shielding chamber 303. The front end of the second shielding chamber 303... The UV sterilization chamber 2 is equipped with a second door 306. The shielding mechanism 3 includes a first lead curtain 307 and a second lead curtain 308. The first lead curtain 307 is installed at the left end of the UV sterilization chamber 2, and the second lead curtain 308 is installed at the right end of the UV sterilization chamber 2. The first shielding chamber 301 is fixedly installed at the right end of the UV sterilization chamber 2. The first door 305 is installed at the front end of the first shielding chamber 301. The first nylon curtain 302 is installed at the right end of the first shielding chamber 301. Multiple first nylon curtains 302 are distributed from front to back on the first shielding chamber 301.

[0029] See Figure 1 , Figure 4 , Figure 6 and Figure 7 Initially, before activation, the shielding mechanism 3 needs to be installed on the ultraviolet sterilization chamber 2. The first shielding chamber 301 is fixedly installed on the left end of the ultraviolet sterilization chamber 2, and the second shielding chamber 303 is fixedly installed on the right end of the ultraviolet sterilization chamber 2. The ultraviolet sterilization chamber 2, the first shielding chamber 301, and the second shielding chamber 303 together form a corridor. When activated, the ultraviolet disinfection lamps and conveyor belt 1 inside the ultraviolet sterilization chamber 2 are activated. The conveyor belt 1 transports materials from left to right. The materials pass through the second nylon curtain 304. The second nylon curtain 304 is relatively soft and will not affect the normal transport of materials. After the materials reach the inside of the ultraviolet sterilization chamber 2, the ultraviolet disinfection lamps can perform disinfection and sterilization operations on the materials.

[0030] Among them, the shielding mechanism 3 is installed at both ends of the ultraviolet sterilization chamber 2 to shield and block the ultraviolet rays overflowing from the ultraviolet sterilization chamber 2. It can effectively block ultraviolet rays and prevent ultraviolet rays from spreading to the outside, thus effectively protecting the safety of the production line and the safety of the operators. In addition, the first nylon curtain 302 and the second nylon curtain 304 are made of nylon fabric, which can block ultraviolet rays to a certain extent, while also being tough and not obstructing materials, ensuring that materials are effectively transported.

[0031] The feeding mechanism 4 includes a first rotating rod 402 and a first lever 404. The first lever 404 is fixedly installed on the outer wall of the first rotating rod 402. Multiple first levers 404 are distributed on the first rotating rod 402 from left to right. A first bearing frame 401 is installed on the inner wall of the first protective chamber 301. The first bearing frame 401 is looped around the first rotating rod 402. A first transmission gear 403 is fixedly installed at both the front and rear ends of the first rotating rod 402. The first transmission gear 403 is located on the upper surface of the conveyor belt 1. A second bearing frame 405 is fixedly installed on the inner wall of the ultraviolet sterilization chamber 2. A second rotating rod 406 is installed on the second bearing frame 405. A second lever 408 is fixedly installed on the outer wall of the second rotating rod 406. Multiple second levers 408 are distributed on the second rotating rod 406 from front to back. A second transmission gear 407 is fixedly installed at both the front and rear ends of the second rotating rod 406. The second transmission gear 407 is located on the upper surface of the conveyor belt 1.

[0032] See Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The material feeding mechanism 4 is a transmission structure. When the conveyor belt 1 is driven, the power of the conveyor belt 1 is transmitted to the first transmission toothed disc 403 and the second transmission toothed disc 407. The first transmission toothed disc 403 then drives the first rotating rod 402 and the first lever 404 to rotate. At this time, the first lever 404 can move the material on the left side of the first lead curtain 307, which can effectively move the material and prevent the material from accumulating at the first lead curtain 307. This is because the first lead curtain 307 can block ultraviolet rays and radiation, but it is relatively hard. Similarly, the second transmission toothed disc 407 drives the second rotating rod 406 and the second lever 408 to rotate. At this time, the second lever 408 can move the material on the left side of the second lead curtain 308, which can effectively move the material and prevent the material from accumulating at the second lead curtain 308.

[0033] The feeding mechanism 4 adopts a transmission structure and does not require separate power. It can drive the first rotating rod 402 and the second rotating rod 406 inside the feeding mechanism 4 with the power of the conveyor belt 1. The first lever 404 and the second lever 408 can move the material on the conveyor belt 1. In particular, before the first lead curtain 307 and the second lead curtain 308, the first lead curtain 307 and the second lead curtain 308 are relatively hard and can easily block the material flow. By moving the feeding mechanism 4, the material blockage can be avoided and the material can be effectively conveyed.

[0034] The working principle of this utility model is as follows: When activated, the ultraviolet disinfection lamps and conveyor belt 1 inside the ultraviolet sterilization chamber 2 are turned on. The conveyor belt 1 transports materials from left to right. The materials pass through the second nylon curtain 304. The second nylon curtain 304 is relatively soft and will not affect the normal transport of materials. After the materials reach the interior of the ultraviolet sterilization chamber 2, the ultraviolet disinfection lamps can perform sterilization and disinfection operations on the materials. When the conveyor belt 1 is running, the power is transmitted to the first transmission gear plate 403, which in turn drives the rotation of the first rotating rod 402 and the first lever 404, so that the first lever 404 can smoothly move the materials and prevent the materials from accumulating at the first lead curtain 307. Since the material of the first lead curtain 307 is relatively hard, it may cause material blockage. Similarly, the operation of the second transmission gear plate 407 also drives the synchronous rotation of the second rotating rod 406 and the second lever 408. Through the reasonable layout of the second lever 408, the second lead curtain 308 can be moved smoothly. The material agitation on the left side of the 08 conveyor further prevents material accumulation on the conveyor belt 1, ensuring a smooth process. The second lead curtain 308 also has the function of blocking ultraviolet rays, ensuring that the material can be effectively processed in an undisturbed environment during sterilization. The operation of the entire material agitation mechanism 4 relies on the power of the conveyor belt 1, without the need for additional power. This not only reduces the complexity of the equipment but also improves the overall work efficiency. Through this ingenious transmission structure, the material agitation mechanism 4 can continuously play a role in the material conveying process, effectively preventing material blockage in front of the lead curtain and ensuring that the material passes through the processing area of ​​the ultraviolet sterilization oven quickly and evenly. Through the above design, the sealing mechanism of the ultraviolet sterilization oven not only improves the flowability of the material and avoids production delays caused by material accumulation but also ensures the stability and reliability of the sterilization effect, thereby improving the overall work efficiency and service life of the equipment.
