TECHNICAL FIELD
[0001] The application relates to the processing technology field of down quilts, in particular to a sterilization device for down quilt processing. BACKGROUND
[0002] Down quilts are favored by consumers and have a growing market demand due to their lightness, warmth, good air permeability and other advantages. Down (mainly duck down or goose down), the core filling material of down quilts, is a natural animal protein fiber that is extremely prone to contamination and breeding of microbial pollutants such as bacteria, viruses, dust mites and fungi during collection, processing, storage and transportation.
[0003] These microorganisms not only may produce odor, affecting product quality and user experience, but more importantly, some of them (such as certain bacteria, dust mites and their excrement) are common allergens that may cause respiratory discomfort, skin allergies and other health problems in users, especially in people with allergic constitution. Therefore, in the production process of down quilts, thorough and efficient sterilization and mite removal treatment of the filling down is a key process to ensure product quality and safety and improve consumer health protection level.
[0004] Among them, the DNA / RNA structure of microorganisms is destroyed by ultraviolet rays (especially UVC band), so that they are inactivated. This method has the advantages of no chemical residues, relatively simple operation, little effect on the physical properties of down, and therefore is more and more widely used in the field of down processing; For example, the patent with publication number CN216639901U discloses a comprehensive sterilization device for down quilt processing. The patent facilitates the lifting of down in the sterilization box by the rotation of the stirring mechanism, and simultaneously sprays and sterilizes the down through the atomizing nozzles on the sterilization box; In the actual sterilization process, the DNA / RNA structure of microorganisms is destroyed by ultraviolet rays to inactivate them for sterilization. However, only the microorganisms on the surface of the down may be killed, while the mites and eggs deposited in the middle and lower layers are difficult to be effectively inactivated due to being shielded by the upper layer of down. Therefore, for the production of down quilts with high quality and high safety, relying only on this surface static irradiation is far from enough.
[0005] Therefore, it is necessary to provide a sterilization device for down quilt processing to solve the above problems.
[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

Then the down quilt after quality inspection is placed in the sterilization device for sterilization and mite removal.
[0024] Through the above scheme, the down quilt is subjected to comprehensive sterilization and mite removal before being packed, which improves the quality of the product and effectively improves the use experience of customers.
[0025] Embodiment two As Figures 1-2As shown, the present application provides a sterilization device for down comforter processing, which is installed before the filling process of the down comforter production line, mainly used for deep sterilization and mite removal of loose down. Specifically, the sterilization device for down comforter processing comprises a support 1 fixed vertically on the ground, and a conveying device 2 is arranged at the upper end of the support 1. The conveying device 2 adopts a conveying belt conveying assembly with existing technology, and the conveying device 2 has a conveying belt 20. The conveying device 2 is driven by a motor-driven roller for one-way conveying, and the conveying device 2 is used to carry and transport the down to be processed. In order to perform closed sterilization on the down on the conveying belt 20, a sterilization mechanism 3 is arranged above the conveying belt 20 at the middle position of the support 1. The sterilization mechanism 3 comprises a sterilization box 30 fixedly arranged at the middle of the support 1. The length direction of the sterilization box 30 is consistent with the advancing direction of the conveying belt 20. A guide inlet 31 is formed at the feeding end of the sterilization box 30, and a guide outlet 32 is correspondingly formed at the discharging end. The size of the guide outlet 32 and the guide inlet 31 is greater than the width of the conveying belt 20 to ensure smooth passage of the down. Meanwhile, metal baffles 34 that can slide up and down are embedded outside the guide inlet 31 and the guide outlet 32. When the baffle 34 moves down, it can seal the port to prevent ultraviolet light leakage during sterilization. And a plurality of sterilization lamp tubes 35 are embedded at equal intervals in the inner top wall of the sterilization box 30. The lamp tube 35 adopts an ultraviolet sterilization lamp. The radiation range of the lamp tube 35 can cover the entire width of the conveying belt 20. Thus, when the down enters the sterilization box 30, the baffle 34 is closed and the lamp tube 35 is turned on, which can preliminarily sterilize the surface layer of the down with ultraviolet light. Embodiment three In order to further kill the mites deposited in the lower layer of the down, such as Figures 1-4 As shown, a turning mechanism 4 is additionally arranged inside the sterilization box 30 near one side of the guide outlet 32. The turning mechanism 4 comprises a fixed plate 40 fixedly arranged on the side wall of the sterilization box 30. A transmission assembly 41 is horizontally mounted on the fixed plate 40. The transmission assembly 41 adopts a lead screw transmission assembly with existing technology. The transmission assembly 41 has a sliding block 42 thereon, and a crossbeam 43 is fixedly arranged on one side of the sliding block 42. The installation direction of the crossbeam 43 is parallel to the advancing direction of the conveying belt 20. The crossbeam 43 has a mounting end on one side, and a motor 45 is fixedly arranged on the mounting end. The output end of the motor 45 is fixedly provided with a stirring paddle 46, which is attached to the surface of the conveying belt 20. A plurality of obliquely downward irradiating sterilization floodlights 44 are embedded on the other side of the crossbeam 43. It should be noted that the slider 42 is initially located on the side of the outlet 32. When the transmission component 41 drives the slider 42 to move towards the inlet 31, the stirring paddle 46 first contacts the down layer and performs a tumbling operation. Immediately following, the germicidal spotlight 44 irradiates the tumbled down in a directional manner. The radiation direction of the germicidal spotlight 44 is directed towards the working area of the stirring paddle 46. During this process, the stirring paddle 46 and the germicidal spotlight 44 maintain a certain distance to ensure that the mites can be fully exposed to the germicidal light after tumbling. Example 4 To further and thoroughly remove the dead mites after extermination, such as Figures 1-5 As shown, a mite suction mechanism 5 is integrated at the bottom of the support 1. The mite suction mechanism 5 includes a screen hole 51 evenly opened on the surface of the conveyor belt 20. At the same time, a temporary storage box 53 is provided on the support 1 directly below the conveyor belt 20. The top surface of the temporary storage box 53 is an open dust collection trough, and the edge of the temporary storage box 53 maintains a gap with the lower surface of the conveyor belt 20. A vacuum cleaner 50 is installed at the bottom of the bracket 1. The vacuum cleaner 50 has a hose 54 at its input end, which is connected to a temporary storage box 53. A storage box 55 is fixedly installed on one side of the bracket 1, and the output end of the vacuum cleaner 50 is connected to the storage box 55. When the vacuum cleaner 50 is started, it can generate suction, so that the mites to be killed can be sucked into the temporary storage box 53 through the sieve 51, and finally sucked into the storage box 55 through the hose 54 for centralized treatment. Based on the above sterilization device, this application provides a complete sterilization process as follows: First, raise the inlet 31 baffle 34, start the conveyor belt 20 to send the down into the sterilization box 30, and close the baffle 34 after the down has completely entered. The second step is to turn on the top-mounted germicidal lamp 35 and irradiate it for 30 seconds to kill surface microorganisms. The third step is to start the flipping mechanism 4: the screw drive assembly 41 drives the slider 42 to move from the outlet 32 to the inlet 31 at a certain speed, and simultaneously turn on the motor 45 and the germicidal spotlight 44. The stirring paddle 46 tumbles the down layer to expose the deep mites, and the germicidal spotlight 44 inactivates them immediately. The one-way operation time of the continuous movement of the stirring paddle 46 and the germicidal spotlight 44 is 1.2-1.5 times the length of the sterilization box 30. Fourth step, turn on the vacuum cleaner 50. The mite carcasses fall into the temporary storage box 53 through the sieve hole 51 and are then drawn into the storage box 55 through the hose 54. The vacuum cleaner 50 is turned off 10 seconds after the flipping mechanism 4 is reset to ensure that the residual mites are completely removed. Fifth step, raise the baffle 34 of the outlet 32, and the conveyor belt 20 will output the sterilized down, while the slider 42 will reset to prepare for the next cycle of operation.
[0026] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
