Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric sterilization technology, specifically to a nonwoven fabric sterilization and disinfection device. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, is mainly made of polyester fiber and is widely used in fields such as heat insulation, masks, clothing and medical applications.

[0003] In the existing technology, when sterilizing and disinfecting non-woven fabrics, the dust and other contaminants on the surface of the non-woven fabric are usually cleaned by brushes in the sterilization and disinfection device first, and then the non-woven fabric is conveyed for sterilization and disinfection. This can ensure that the subsequent sterilization and disinfection process is more effective and can avoid dust and impurities affecting the sterilization and disinfection effect.

[0004] However, since the brush used to clean the surface of the non-woven fabric remains stationary, and the contact time between the stationary brush and the non-woven fabric is short, and the stationary brush can only rely on the movement of the non-woven fabric itself to generate friction, this friction is usually small and insufficient to effectively remove stubborn dust or other contaminants. This can easily lead to uneven cleaning and affect the subsequent sterilization and disinfection effect of the non-woven fabric. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a non-woven fabric sterilization and disinfection device to solve the technical problem in the prior art that the brush used to clean the surface of the non-woven fabric before sterilization and disinfection is in a stationary state, the contact time between the brush and the non-woven fabric is short and the friction is usually small, which easily leads to uneven cleaning and affects the effect of subsequent sterilization and disinfection of the non-woven fabric.

[0006] This utility model is achieved through the following technical solution:

[0007] A nonwoven fabric sterilization and disinfection device includes a sterilization box and a nonwoven fabric transversely threaded in the sterilization box. The upper and lower surfaces of the nonwoven fabric are respectively provided with a brush for brushing the surface of the nonwoven fabric. The ends of the two brushes are respectively connected to a migration mechanism for moving the brushes to reciprocate linear motion perpendicular to the direction of movement of the nonwoven fabric.

[0008] Furthermore, the migration mechanism includes two mounting rods respectively fixed at both ends of the brush, the free ends of the two mounting rods extending outward through the sterilization box, and the ends are fixed with limiting blocks, and one of the mounting rods is fitted with a sleeve.

[0009] A mounting frame is fixedly provided on the outside of the sterilization box. A rotating shaft is rotatably connected to the mounting frame. The two ends of the rotating shaft extend to the two sides of the mounting frame, respectively. A turntable is fixedly provided at one end of the rotating shaft. A driving component for driving the turntable to rotate is connected to the other end of the rotating shaft. A connecting component for pulling the sleeve and the mounting rod to slide relative to each other is connected to the turntable.

[0010] Furthermore, the connecting component includes a support rod A fixedly connected to the turntable, and the support rod A is eccentrically arranged on the turntable. A support rod B is fixedly provided on the sleeve, and the center line of the support rod B is perpendicular to the center line of the sleeve. A connecting rod is hinged between the support rod B and the support rod A.

[0011] Furthermore, the driving component includes a bracket fixedly connected to the sterilization box, a power source is mounted on the bracket, and the output end of the power source is connected to the rotating shaft.

[0012] Furthermore, the driving component also includes two transmission components A, which are respectively fixed on the two rotating shafts, and the two transmission components A are connected by a transmission component B.

[0013] Furthermore, a spring is fitted over the mounting rod, and the spring is located on the mounting rod away from the sleeve.

[0014] Furthermore, the brush includes a brush holder fixedly connected between the two mounting rods, and the brush holder has a plurality of bristles on the side facing the nonwoven fabric.

[0015] Furthermore, the brush holder is hollow inside, and the side of the brush holder with the brush has several through holes communicating with the inside of the brush holder. Each of the two brush holders is connected to a vacuum cleaner pipe, the other end of which extends out of the sterilization box and is connected to a vacuum cleaner.

[0016] Furthermore, the inner wall of the sterilization chamber is provided with a linear array of several sterilization lamps for sterilizing and disinfecting the cleaned non-woven fabric.

[0017] The beneficial effects of this utility model are as follows:

[0018] During the nonwoven fabric conveying process, compared with the brush in the prior art which is stationary, the brush of this utility model moves back and forth in a straight line perpendicular to the direction of movement of the nonwoven fabric under the action of the migration mechanism to clean the nonwoven fabric. The contact time between the brush and the nonwoven fabric is longer and the contact area is larger, which can more effectively remove dust and impurities from the surface of the nonwoven fabric.

[0019] Secondly, the moving brush can generate greater mechanical force through its own movement, which can better penetrate the fiber structure of the nonwoven fabric, thereby removing dust and impurities more thoroughly.

[0020] Meanwhile, the moving brush can continuously agitate the dust particles on the surface of the nonwoven fabric by sweeping back and forth, making them easier to remove.

[0021] Furthermore, the moving brush can cover a larger area, and by constantly moving, it ensures that each area is cleaned evenly, thereby improving the cleaning effect of the brush on the non-woven fabric and further ensuring the subsequent sterilization and disinfection effect of the non-woven fabric.

[0034] Please see Figure 1 , Figure 2 and Figure 7 This utility model provides a technical solution: a non-woven fabric sterilization and disinfection device, including a sterilization box 1 and a non-woven fabric 2 transversely threaded in the sterilization box 1. The sterilization box 1 is provided with a conveying mechanism for conveying the non-woven fabric 2. The specific conveying structure and working principle are existing technologies and will not be described in detail here. The upper and lower surfaces of the non-woven fabric 2 are respectively provided with a brush 3 for brushing the surface of the non-woven fabric 2. The brush 3 includes a brush seat 31 fixedly connected between two mounting rods 41. The brush seat 31 has a plurality of bristles 32 on the side facing the non-woven fabric 2. The bristles 32 are in contact with the surface of the non-woven fabric 2, and the overall length of the brush 3 is greater than the width of the non-woven fabric 2. The ends of the two brushes 3 are respectively connected to a migration mechanism 4 for migrating the brushes 3 to reciprocate linear motion perpendicular to the direction of movement of the non-woven fabric 2.

[0035] Please see Figure 1 , Figure 2 and Figure 7 The brush holder 31 is hollow inside, and a plurality of through holes 311 communicating with the inside of the brush holder 31 are opened on the side of the brush 3. A vacuum tube 5 is connected to each of the two brush holders 31. The other end of the vacuum tube 5 extends out of the sterilization box 1 and is connected to a vacuum cleaner 6. When the vacuum cleaner 6 works in conjunction with the vacuum tube 5, the dust or other impurities brushed off by the brush 3 can be adsorbed through the through holes 311 when the brush 3 is working. The output end of the vacuum cleaner 6 can be connected to a filter device (not shown) in the prior art to collect the dust or other impurities sucked up by the vacuum cleaner 6.

The sterilization lamps 7 are high-power LED UVC ultraviolet lamps in the prior art. The distance between the sterilization lamps 7 and the non-woven fabric 2 is between 10 and 20 centimeters. It has a fast and efficient sterilization and disinfection effect. The specific working principle of the sterilization lamps 7 is the prior art and will not be described in detail here.

[0037] Regarding the aforementioned migration mechanism 4:

[0038] Please see Figures 2 to 6 The migration mechanism 4 includes two mounting rods 41 fixed at both ends of the brush 3. The free ends of the two mounting rods 41 extend outward through the sterilization box 1, and the ends are fixed with limiting blocks 42. One of the mounting rods 41 is fitted with a sleeve 43, and the other mounting rod 41 is fitted with a spring 49.

[0039] A mounting frame 44 is fixedly provided on the outside of the sterilization box 1. A rotating shaft 45 is rotatably connected to the mounting frame 44. The two ends of the rotating shaft 45 extend to the two sides of the mounting frame 44 respectively. A turntable 46 is fixedly provided at one end of the rotating shaft 45. A driving component 48 for driving the turntable 46 to rotate is connected to the other end of the rotating shaft 45. A connecting component 47 for pulling the sleeve 43 and the mounting rod 41 to slide relative to each other is connected to the turntable 46.

[0040] Regarding the connecting component 47:

[0041] Please see Figure 4 and Figure 6 The connecting component 47 includes a support rod A471 fixedly connected to the turntable 46, and the support rod A471 is eccentrically arranged on the turntable 46. A support rod B472 is fixedly provided on the sleeve 43. The center line of the support rod B472 is perpendicular to the center line of the sleeve 43. A connecting rod 473 is hinged between the support rod B472 and the support rod A471.

[0042] Regarding the drive component 48:

[0043] Please see Figure 1 , Figure 5 and Figure 6The driving component 48 includes a bracket 481 fixedly connected to the sterilization box 1. A power source 482 is mounted on the bracket 481. In this application, the power source 482 is an electric motor. The output end of the power source 482 is connected to the rotating shaft 45. The driving component 48 also includes two transmission components A483 respectively fixedly mounted on the two rotating shafts 45. The transmission components A483 can be selected from the prior art, such as a gear plate or a pulley. The two transmission components A483 are connected by a transmission component B484. The transmission component B484 is selected from the corresponding chain or belt of the transmission component A483.

[0044] The working principle of this utility model is as follows: The non-woven fabric 2 is conveyed intermittently in the sterilization box 1 through the conveying mechanism in the sterilization box 1 under the control of the controller. It is input from one side of the sterilization box 1 and output from the other side of the sterilization box 1. Finally, it is wound and rolled up on the external winding mechanism. During the process of the non-woven fabric 2 staying and being conveyed in the sterilization box 1, the surface of the non-woven fabric 2 is irradiated by the sterilization lamp 7, thereby playing a role in sterilizing and disinfecting the non-woven fabric 2.

[0045] During the conveying process of the nonwoven fabric 2, the controller controls the power source 482 to start. The power source 482 drives one of the rotating shafts 45 to rotate. When the rotating shaft 45 rotates, it drives the corresponding turntable 46 to rotate. Furthermore, through the cooperation of the transmission component A483 and the transmission component B484, the other rotating shaft 45 and the turntable 46 can be driven to rotate synchronously when the rotating shaft 45 rotates. Thus, the power source 482 can drive both turntables 46 to rotate simultaneously.

[0046] When the turntable 46 rotates, it drives the support rod A471 to move in a circular motion. Since the support rod A471 is eccentrically set on the end face of the turntable 46, the rotation of the turntable 46 can drive the connecting part 47 to swing and pull the sleeve 43 outward. When the sleeve 43 moves, it pulls the mounting rod 41 outward and causes relative sliding between it and the sterilization box 1, so as to drive the brush 3 to reciprocate linearly perpendicular to the direction of movement of the non-woven fabric 2 to clean the non-woven fabric 2. Compared with the prior art where the brush 3 is in a stationary state, the contact time between the brush 3 and the non-woven fabric 2 in this utility model is longer and the contact area is larger, so that dust and impurities on the surface of the non-woven fabric can be removed more effectively.

[0047] Secondly, the moving brush 3 can generate greater mechanical force through its own movement, which can better penetrate the fiber structure of the nonwoven fabric 2, thereby removing dust and impurities more thoroughly.

[0048] At the same time, the moving brush 3 can continuously disturb the dust particles on the surface of the non-woven fabric 2 by constantly sweeping back and forth, making them easier to remove.

[0049] Furthermore, the moving brush 3 can cover a larger area, and by constantly moving, it ensures that each area is cleaned evenly, thereby improving the cleaning effect of the brush 3 on the non-woven fabric 2 and further ensuring the subsequent sterilization and disinfection effect of the non-woven fabric 2.

[0050] During the movement of the brush 3, the limiting block 42 cooperates with the spring 49 to facilitate the return of the brush 3 to its original position. The vacuum cleaner 6 works in conjunction with the vacuum tube 5 to absorb the dust or other impurities brushed off by the brush 3 through the through hole 311, preventing the dust or other impurities from falling back onto the surface of the non-woven fabric 2 and causing secondary pollution.

[0051] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
