Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment, and in particular to a sterilization equipment for finished nonwoven fabrics. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers into a web through airflow or mechanical means using polymer chips, short fibers, or filaments, and then reinforcing it through hydroentangling, needle punching, or hot rolling. Finally, it undergoes finishing processes to form a non-woven fabric. After production, nonwoven fabric needs to be sterilized and stored.

[0003] Chinese Patent No. CN219814770U discloses a sterilization device for finished nonwoven fabrics, including a housing, a supporting leg fixedly installed at the bottom of the housing, guide rollers movably installed at both ends of the housing, a sealed cover fixedly installed at the top of the housing, and a winding mechanism fixedly installed on the sealed cover. The winding mechanism includes a drive motor, a positioning bracket, a winding roller, a drive shaft, and a positioning leg. The positioning leg is fixedly installed on the sealed cover, and a positioning bracket is fixedly installed at the upper end of the positioning leg. A drive shaft is movably installed at the upper end of the positioning bracket, and a winding roller is fixedly installed on the drive shaft. Sterilization mechanisms are fixedly installed at the bottom of both the housing and the sealed cover. When the nonwoven fabric passes through the interior of the housing, an ultraviolet lamp can be activated. After the ultraviolet lamp is activated, the ultraviolet light of an appropriate wavelength can destroy the molecular structure of DNA or RNA in the cells of microorganisms, causing the death of both growing and regenerating cells, thus achieving the sterilization effect.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing sterilization equipment for finished nonwoven fabrics cannot evenly and comprehensively spray and apply disinfectant to the nonwoven fabric, which affects the sterilization and disinfection effect of the nonwoven fabric. At the same time, the disinfectant cannot be dried quickly after application, which affects the subsequent winding and practical use. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to evenly and comprehensively apply disinfectant to non-woven fabric and then quickly dry it, and to propose a sterilization device for finished non-woven fabric.

[0006] The technical solution of this utility model: A sterilization device for finished nonwoven fabrics, comprising a base plate, a sterilization chamber disposed on the top of the base plate, and a conveying port disposed on the side of the sterilization chamber; further comprising:

[0007] A sealing sterilization mechanism is installed on the sterilization chamber to seal the chamber and to sterilize and dry the non-woven fabric by high-temperature heating.

[0008] The spraying disinfection mechanism is located inside the sterilization chamber and is used to repeatedly spray hydrogen peroxide solution to sterilize and disinfect non-woven fabrics.

[0009] The disinfection plate is rotatably mounted on the spray disinfection mechanism. Limiting strips are provided on the end face of the disinfection plate. Three disinfection plates are arranged in a ring around the spray disinfection mechanism. Rotating rods are rotatably mounted on the ends of the disinfection plates. Two limiting strips are symmetrically arranged about the disinfection plate, and the rotating rods are positioned between the limiting strips. The disinfection plate rotates under the drive of the spray disinfection mechanism. When the disinfection plate rotates to the top, it applies disinfectant to the non-woven fabric. During this process, the disinfection plate rotates on the rotating rods, while the limiting strips control the rotation range of the disinfection plate.

[0010] Preferably, it also includes a winding assembly, which includes a fixing frame, a motor and a winding roller;

[0011] The fixing frame is located on the top of the base plate, the motor is located on the side of the fixing frame, and the take-up roller is located at the output end of the motor.

[0012] Preferably, the sealed sterilization mechanism includes a heater, a connecting plate, a conveying roller, and a sealing assembly;

[0013] The heater is located inside the sterilization chamber and at the top. Multiple heaters are symmetrically arranged about the sterilization chamber. The connecting plate is located on the side of the sterilization chamber. The conveying roller is located at the end of the connecting plate away from the sterilization chamber.

[0014] The sealing component is located on the inner side of the sterilization chamber and is used to seal the sterilization chamber during the sterilization of non-woven fabrics during transport.

[0015] Preferably, the sealing assembly includes a connecting shaft, a sealing plate, a spring, and a fixing plate;

[0016] The connecting shaft is located inside the sterilization chamber, the sealing plate is rotatably located outside the connecting shaft, the spring is located on the side of the sealing plate, and the fixing plate is located at the end of the spring away from the sealing plate.

[0017] Preferably, the spray disinfection mechanism includes a liquid storage tank, an infusion port, a water pump, a nozzle, and an application assembly;

[0018] The liquid storage tank is located on the top of the base plate, the infusion port is located on the top of the liquid storage tank, the water pumping pipe is located inside the liquid storage tank, and the nozzle is located at the end of the water pumping pipe.

[0019] The applicator is located on the sterilization chamber and is used to automatically rotate and apply the disinfectant solution from the sterilization plate onto the non-woven fabric.

[0020] Preferably, the coating assembly includes a second motor, a rotating shaft, a rotating frame, and a mounting plate;

[0021] Motor 2 is located on the outside of the sterilization chamber, the rotating shaft is located at the output end of motor 2, the rotating frame is located on the outside of the rotating shaft, the mounting plate is located at the end of the rotating frame away from the rotating shaft, spring 2 is located at the end of the mounting plate away from the rotating frame, and a connecting rod is located at the end of spring 2 away from the mounting plate. The end of the connecting rod is connected to the side of the rotating rod.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. Through the spray disinfection mechanism, the nozzle draws hydrogen peroxide disinfectant from the storage tank and sprays it onto the disinfection plate. Motor 2 drives the disinfection plate to rotate and thus disinfect the non-woven fabric. During the disinfection process, the disinfection plate can be finely adjusted by spring 2 and the limiting strip to ensure that the disinfection plate can completely adhere to the non-woven fabric. This ensures that the hydrogen peroxide solution evenly covers all areas, avoiding disinfection blind spots caused by angle deviation in traditional fixed disinfection plates. Furthermore, when the disinfection plate adheres to the surface of the non-woven fabric, the hydrogen peroxide solution forms a liquid film locally, prolonging the contact time between the disinfectant and microorganisms. Compared with traditional spraying methods, the sterilization efficiency is improved.

[0024] 2. Through the setting of the sealed sterilization mechanism, the heater heats the inside of the sterilization chamber to carry out high-temperature sterilization. During the sterilization process, the sealing plate seals the sterilization chamber, which can create an independent high-temperature environment inside, preventing external microorganisms, dust and other contaminants from entering. At the same time, it maintains the uniformity of temperature inside the chamber, avoiding incomplete sterilization due to local temperature differences, and quickly removes residual moisture from the surface and inside of the non-woven fabric after sterilization.

Detailed Implementation

[0031] Example 1

[0032] like Figures 1-3 As shown, the present invention proposes a sterilization device for finished nonwoven fabrics, comprising a base plate 1, a sterilization chamber disposed on the top of the base plate 1, a conveying port 3 disposed on the side of the sterilization chamber 2, a sealing sterilization mechanism, a spraying disinfection mechanism, and a disinfection plate 512.

[0033] The sealing sterilization mechanism is installed on the sterilization chamber to seal the sterilization chamber and to sterilize and dry the non-woven fabric by high-temperature heating.

[0034] The spraying disinfection mechanism is located inside the sterilization chamber and is used to repeatedly spray hydrogen peroxide solution to sterilize and disinfect non-woven fabrics.

[0035] The disinfection plate 512 is rotatably mounted on the spray disinfection mechanism. The end face of the disinfection plate 512 is provided with a limit strip 513. Three disinfection plates 512 are arranged in a ring around the spray disinfection mechanism. A rotating rod 511 is rotatably mounted on the end of the disinfection plate 512. Two limit strips 513 are symmetrically arranged about the disinfection plate 512. The rotating rod 511 is located between the limit strips 513. The disinfection plate 512 rotates under the drive of the spray disinfection mechanism. When the disinfection plate 512 rotates to the top, it applies disinfectant to the non-woven fabric. During this process, the disinfection plate 512 rotates on the rotating rod 511, while the limit strips 513 control the rotation range of the disinfection plate 512.

[0036] The winding assembly includes a fixed frame 401, a motor 402, and a winding roller 403. The fixed frame 401 is located on the top of the base plate 1, the motor 402 is located on the side of the fixed frame 401, and the winding roller 403 is located at the output end of the motor 402.

The side of the fixing plate 607 is connected to the inside of the sterilization chamber. One end of the nonwoven fabric is passed through the conveying roller 603 and fixed to the winding roller 403. During the conveying process, the two conveying rollers 603 straighten the nonwoven fabric. At the same time, the two sealing plates 605 are in contact with the nonwoven fabric under the action of the spring 606, thereby maintaining the sealing effect of the sterilization chamber. Then, the heater 601 is activated to heat the inside of the sterilization chamber, thereby sterilizing the nonwoven fabric at high temperature.

[0038] Example 2

[0039] like Figures 4-5 As shown, this utility model proposes a sterilization device for finished nonwoven fabrics. Compared with Embodiment 1, this embodiment details the structure of the spraying disinfection mechanism.

[0040] The spray disinfection mechanism includes a storage tank 502, an inlet 503, a water pipe 506, a nozzle 507, and an application assembly.

The water pipe 506 is located inside the storage tank 502, and the nozzle 507 is located at the end of the water pipe 506. The nozzle 507 controls the water pipe 506 to draw the disinfectant and spray it onto the application assembly. The disinfectant that is not sprayed onto the application assembly flows back into the storage tank 502 through the guide slot in the middle part of the storage tank 502 to avoid waste. The application assembly is located on the sterilization chamber and is used to automatically rotate and apply the disinfectant on the disinfection plate 512 onto the non-woven fabric.

During the rotation, disinfection plate 512 can be finely adjusted in angle under the action of spring 2 509 and limiting strip 513, so that disinfection plate 512 and non-woven fabric can be in contact and stick together.

[0041] In summary, when using this invention, one end of the nonwoven fabric is passed through the conveyor roller 603 and fixed to the take-up roller 403. The motor 402, motor 501, and heater 601 are started. Motor 402 drives the take-up roller 403 to rotate, pulling and winding the nonwoven fabric. During this process, the two conveyor rollers 603 straighten the nonwoven fabric. Simultaneously, the two sealing plates 605 are pressed against the nonwoven fabric under the action of spring 606, thus maintaining the sealing effect of the sterilization chamber. The heater 601 heats the inside of the sterilization chamber, thereby sterilizing the nonwoven fabric. The nonwoven fabric undergoes high-temperature sterilization. Simultaneously, motor 501 drives shaft 504 to rotate, which in turn drives rotating frame 505. Rotating frame 505 drives sterilization plate 512 to rotate via rotating rod 511. During rotation, sterilization plate 512 can be finely adjusted in angle under the action of spring 509 and limiting strip 513, ensuring that sterilization plate 512 and nonwoven fabric are in close contact. This allows for the spraying of hydrogen peroxide solution to sterilize the nonwoven fabric. The high-temperature environment inside the sterilization chamber dries the sterilized, damp nonwoven fabric, facilitating subsequent work.
