Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabrics, and in particular to a sterilization device and a sterilization method for non-woven fabric production and processing. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is produced using polyester fiber and polyester fiber materials and is made through a needle-punching process. Non-woven fabric has no warp and weft threads, is very convenient for cutting and sewing, and is light in weight and easy to shape. It is not woven by interweaving and knitting one by one yarns, but the fibers are directly bonded together by physical methods. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple raw material sources.

[0003] Some patent documents related to the technical field of non-woven fabrics are disclosed in the prior art. The Chinese patent with the application number CN202121657797.4 discloses a dust removal and sterilization device for non-woven fabric production, including a cabinet, a dust removal channel, a sterilization channel, a conveying mechanism, an embedded mechanism, a dust removal mechanism, a first rotation drive mechanism, a ventilation mechanism, an ultraviolet lamp tube, and a support mechanism. The dust removal channel is located in the upper part of the cabinet, the sterilization channel is located in the lower part of the cabinet, the conveying mechanism is located inside the dust removal channel and the sterilization channel, the embedded mechanism is located between the dust removal channel and the sterilization channel, the dust removal mechanism is located inside the dust removal channel, the first rotation drive mechanism is located inside the embedded mechanism, and the ventilation mechanism is located at the outer end of the cabinet.

[0004] In the process of sterilizing non-woven fabric in the prior art, the dust on the surface of the non-woven fabric is shaken off by physical hammering. Since non-woven fabric belongs to non-woven cloth and the fibers of non-woven fabric are arranged in a certain direction, during the process of being physically hammered, non-woven fabric is prone to cracking from the right angle direction, thus causing damage to the non-woven fabric and affecting the normal processing of non-woven fabric. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the prior art and propose a sterilization device and a sterilization method for non-woven fabric production and processing.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a sterilization device for non-woven fabric production and processing, including a processing cabinet, the top of the processing cabinet is fixedly connected with a cover plate, and the two sides of the processing cabinet are respectively provided with a feed inlet and a discharge outlet. Two first rotating shafts are rotatably connected to one side of the processing cabinet close to the discharge outlet. Conveyor rollers are fixedly connected to the first rotating shafts. One end of each of the two first rotating shafts penetrates through one side of the processing cabinet and extends to the outside of the processing cabinet and is fixedly connected with a mating gear. The mating gears are meshed with each other. A first rotation driving mechanism is connected to the first rotating shaft;

[0007] A mating conveying mechanism is connected to the processing cabinet, and the mating conveying mechanism is used to convey one end of the non-woven fabric between the two conveyor rollers;

[0008] Two hydraulic cylinders are fixedly installed at the bottom of the cover plate. The bottom ends of the piston shafts of the two hydraulic cylinders are jointly fixedly connected with a U-shaped plate. Both ends of the bottom of the U-shaped plate are fixedly connected with circular shells. A dust suction mechanism is jointly communicated between the circular shells. An opening is provided at the bottom of the circular shell. A rotating plate is rotatably connected to the opening at the bottom of the circular shell. A plurality of circular through holes are arranged in a circumferential array on the rotating plate. A second rotation driving mechanism for synchronously driving the two rotating plates to rotate is connected to the side of the U-shaped plate. A multi-point shaking mechanism for cleaning the surface of the non-woven fabric is connected to the rotating plate;

[0009] A plurality of ultraviolet germicidal lamps are fixedly connected to the bottom of the cover plate in a linear array, and a lamp cover is fixedly connected to the bottom of the ultraviolet germicidal lamp; during operation, in the prior art, during the sterilization of non-woven fabrics, the dust on the surface of the non-woven fabric is shaken off by physical hammering. Since the non-woven fabric belongs to a non-woven fabric and the fibers of the non-woven fabric are arranged in a certain direction, the non-woven fabric is prone to cracking from the right-angle direction during physical hammering, resulting in damage to the non-woven fabric and affecting the normal processing of the non-woven fabric. The technical solution of the present invention can solve the above problems. The specific working method is as follows: One end of the wound non-woven fabric is placed into the processing cabinet from the feed port, and the cooperation of the conveying mechanism moves one end of the non-woven fabric between the two conveying rollers. Then, the first rotation driving mechanism drives one of the first rotating shafts to rotate. The two first rotating shafts rotate in opposite directions through the meshing of the two mating gears, and drive the two conveying rollers to rotate in opposite directions, so that one end of the non-woven fabric passes between the two conveying rollers and continuously conveys the non-woven fabric. During the transmission of the non-woven fabric inside the processing cabinet, two hydraulic cylinders are started. The piston shaft of the hydraulic cylinder drives the U-shaped plate to move downward, so that the circular shell moves downward. The circular shell drives the rotating plate to move downward, and the bottom of the rotating plate is located on the top surface of the non-woven fabric. Through the action of the second rotation driving mechanism, the rotating plate rotates on the top surface of the non-woven fabric, and through the action of the multi-point shaking mechanism, the top surface of the non-woven fabric is regularly and intermittently shaken at multiple points. On the one hand, the dust on the surface of the large-area non-woven fabric can be shaken up by the slight convex movement at multiple points and multiple positions, avoiding the pulling damage caused by single-point heavy beating. On the other hand, the dust suction mechanism sucks air into the inside of the circular shell. The circular shell adsorbs the dust shaken up on the surface and in the fibers of the non-woven fabric in a timely manner through the circular through holes on the surface of the rotating plate, and enters the circular shell. Then, the dust suction mechanism collects the dust in the circular shell. During the movement of the dust-removed non-woven fabric, the surface of the non-woven fabric is sterilized by the irradiation of the ultraviolet germicidal lamp. The rotating plate rotates while fitting on the surface of the non-woven fabric to remove dust, and the multi-point shaking mechanism timely adsorbs the dust shaken out of the non-woven fabric fibers. On the one hand, it is beneficial to improve the cleaning effect of the non-woven fabric. On the other hand, it reduces the damage caused by beating, reduces the degree of processing deformation of the non-woven fabric, prevents the non-woven fabric from vertically cracking along the fiber arrangement direction, and ensures the subsequent processing of the non-woven fabric.

[0010] Preferably, the first rotation driving mechanism includes a first motor and two first pulleys. The first motor is fixedly installed at the bottom of the processing cabinet. The two first pulleys are respectively fixedly connected to the output shaft of the first motor and one of the first rotating shafts. A first transmission belt is connected between the first pulleys in a transmission manner. During operation, the rotation of the output shaft of the first motor drives the first pulley on the output shaft to rotate. Through the transmission of the first transmission belt, one of the first rotating shafts is driven to rotate.

[0011] Preferably, the cooperating conveying mechanism includes two chutes, which are respectively opened on both sides of the processing cabinet. Sliders are slidably connected in the chutes. On one side of the sliders located inside the processing cabinet, rectangular plates are fixedly connected. Two circular rods are fixedly connected between the two rectangular plates. Pressure rings are sleeved on the circular rods. Two fixing pins are fixedly connected to the inner walls of the pressure rings. The fixing pins are slidably inserted into the adjacent circular rods. First springs are sleeved on the fixing pins. The two ends of the first springs are respectively fixedly connected to the circular rods and the pressure rings. A positioning mechanism is connected to the sliders. During operation, one end of the non-woven fabric is placed into the processing cabinet along the feeding port, and one end of the non-woven fabric is placed between the two pressure rings. The pressure rings are squeezed by the elastic force of the first springs, so that the two pressure rings approach each other and elastically clamp one end of the non-woven fabric. The sliders are moved along the chutes to make the sliders approach the two conveying rollers and the non-woven fabric is conveyed by the conveying rollers. When one end of the non-woven fabric enters between the conveying rollers and is conveyed, the sliders are moved in the reverse direction to move the sliders to one side of the feeding port, and then the positions of the sliders are positioned by the positioning mechanism, so that the part of the non-woven fabric located inside the processing cabinet is elastically clamped by the two pressure rings and remains in a taut state during the conveying process, which is convenient for dust suction and shaking on the surface of the non-woven fabric.

[0012] Preferably, the positioning mechanism includes a connecting block and two rectangular bars. The connecting block is fixedly connected to one side of the processing cabinet. Above the connecting block, there is a pull ring. At the bottom of the pull ring, two sliding pins are fixedly connected. The bottom ends of the sliding pins penetrate through the connecting block and extend to the lower side of the connecting block and then are fixedly connected with arc-shaped stoppers. Second springs are sleeved on the sliding pins, and the two ends of each second spring are fixedly connected to the arc-shaped stopper and the connecting block respectively. The two rectangular bars are respectively fixedly connected to one side of the two sliders, and one side of the arc-shaped stopper is located on one side of one of the rectangular bars. During operation, by moving the rectangular bar, the slider is driven to move. When the rectangular bar moves to the side close to the feed port, the top of the rectangular bar contacts and presses against the arc-shaped guiding surface of the arc-shaped stopper, causing the arc-shaped stopper to move upward and compressing the second spring on the sliding pin, resulting in a compressive deformation of the second spring. When the rectangular bar passes through, the elastic force of the second spring presses the arc-shaped stopper to move in the reverse direction and blocks and positions the rectangular bar. When it is necessary to move the slider, pull up the pull ring, and the arc-shaped stopper moves upward to move the rectangular bar.

[0013] Preferably, the dust suction mechanism includes a vacuum cleaner and a U-shaped pipe. The vacuum cleaner is fixedly installed on the top of the cover plate. The U-shaped pipe is located above the two circular shells. The two ends of the U-shaped pipe are respectively fixedly communicated with the tops of the two circular shells. The dust suction end of the vacuum cleaner is fixedly communicated with a telescopic pipe. The end of the telescopic pipe away from the vacuum cleaner penetrates through the cover plate and extends to its lower side and then is fixedly communicated with the U-shaped pipe. During operation, by starting the vacuum cleaner, due to the communication effect of the telescopic pipe and the U-shaped pipe, negative pressure is generated in the two circular shells, causing the rotating plate to adsorb the dust on the non-woven fabric through the circular through hole, and the dust located in the circular shell enters the vacuum cleaner along the U-shaped pipe and the telescopic pipe for collection.

[0014] Preferably, the second rotation driving mechanism includes a second motor and two second rotating shafts. The second motor is fixedly connected to one side of the U-shaped plate. The two second rotating shafts are respectively fixedly connected to the tops of the two rotating plates. The tops of the second rotating shafts all penetrate through the adjacent circular shells and extend above the circular shells and are fixedly connected with second belt pulleys. A third belt pulley is fixedly connected to the output shaft of the second motor. The third belt pulley and the two second belt pulleys are driven by a second transmission belt. The tops of the circular shells are all rotatably connected with abutting pins, and the abutting pins are all in contact with the side surface of the second transmission belt. During operation, by starting the second motor, the output shaft of the second motor drives the third belt pulley to rotate, and drives the two second belt pulleys to rotate through the transmission of the second transmission belt, so as to make the two second rotating shafts rotate, drive the rotating plate to rotate. By arranging two abutting pins on the side surface of the second transmission belt, the second transmission belt is in a taut state, ensuring the transmission effect of the second transmission belt. And through the rotation of the abutting pins, the contact between the abutting pins and the side surface of the second transmission belt is rolling friction, reducing the friction force and the wear on the side surface of the second transmission belt.

[0015] Preferably, the multi-point jitter mechanism includes a plurality of rectangular through grooves and protruding blocks. The rectangular through grooves are arranged in a circumferential array on the rotating plate. Contact rollers are placed in the rectangular through grooves. U-shaped rods are rotatably connected to the contact rollers. The U-shaped rods are all located inside the circular shell. Two limit pins are slidably inserted on the U-shaped rods. The bottom ends of the limit pins are all fixedly connected to the top of the rotating plate. A fourth spring is sleeved on each limit pin. The tops of the U-shaped rods are all fixedly connected with arc-shaped top blocks. The protruding blocks are fixedly connected to the top surface inside the circular shell in a circumferential array. During operation, the rotating plate moves downward and approaches the top surface of the non-woven fabric. The contact rollers contact the top surface of the non-woven fabric and rotate along the top surface of the non-woven fabric during the rotation of the rotating plate. When the arc-shaped surface of the arc-shaped top block contacts the protruding block during the rotation, the arc-shaped top block moves downward, drives the U-shaped rod to move downward along the limit pin, and squeezes the fourth spring to cause the fourth spring to compress and deform. The U-shaped rod drives the contact roller to move downward and generate a top contact on the surface of the non-woven fabric, so as to make the surface of the non-woven fabric bulge. When the arc-shaped top block passes through the protruding block, the elastic action of the fourth spring drives the U-shaped rod to move upward, and the U-shaped rod drives the contact roller to move upward, thus canceling the bulging effect on the surface of the non-woven fabric, and further realizing multi-point and multi-position bulging on the surface of the non-woven fabric, and further making the non-woven fabric vibrate. On the one hand, it can avoid damage caused by single-point knocking. On the other hand, it can realize large-area vibration, so that the dust inside the non-woven fabric is shaken out. And with the support of the contact rollers, a space can be left between the non-woven fabric and the rotating plate for the dust to float out and be sucked away.

[0016] Preferably, rectangular rings are sleeved on the tops of the lamp shades. Two connecting rods are fixedly connected between adjacent rectangular rings. One side of the top of each rectangular ring is fixedly provided with a wiping cotton strip. Two inserting pins are fixedly connected to one side of the rectangular ring close to the U-shaped plate. The inserting pins are all slidably inserted on the U-shaped plate. Fifth springs are sleeved on the inserting pins. Two ends of each fifth spring are respectively fixedly connected to the rectangular ring and the U-shaped plate. A cam is fixedly connected to the surface of the output shaft of the second motor. A connecting frame is fixedly connected to the bottom of the rectangular ring close to the U-shaped plate. The cam is located inside the connecting frame. During operation, when the rotating plate cleans and adsorbs dust on the surface of the non-woven fabric, some unadsorbed dust flutters in the processing cabinet and adheres to the surface of the lamp shade, thus blocking the light source of the ultraviolet germicidal lamp and affecting the sterilization effect. By connecting the rectangular ring and the U-shaped plate through the inserting pins, when the U-shaped plate moves downward through the hydraulic cylinder, the rectangular ring moves downward together with the U-shaped plate and is located below the lamp shade. When the U-shaped plate moves downward, the rectangular ring moves to the top of the lamp shade, so that it will not affect the light projection of the lamp shade. When the second motor starts to clean the dust on the non-woven fabric, the output shaft of the second motor drives the cam to rotate. The protruding end of the cam squeezes the connecting frame, causing the rectangular ring to drive the inserting pins to move along the sliding insertion part, and causing the fifth spring to generate a compressive deformation. When the protruding end of the cam does not squeeze the connecting frame, the elastic action of the fifth spring makes the rectangular ring return to its original position, so that the rectangular ring continuously moves horizontally. During the movement, the wiping cotton strip on the rectangular ring repeatedly moves at the bottom of the lamp shade and cleans the surface of the lamp shade, thereby reducing the dust adhesion on the surface of the lamp shade and reducing the influence of dust on the sterilization of the ultraviolet germicidal lamp.

[0017] Preferably, a dust suction box is fixedly connected to the bottom of the cover plate. A dust suction pipe is fixedly connected to the top of the dust suction box. One end of the dust suction pipe away from the dust suction box penetrates through the cover plate and is fixedly communicated with the dust suction end of the vacuum cleaner. A plurality of communication ports are formed in the bottom of the dust suction box, and the communication ports are located at positions between adjacent two ultraviolet germicidal lamps. A dust suction head is fixedly communicated with the opening of the communication port at the bottom of the dust suction box. A fixing rod is rotatably connected to the bottom of the dust suction box. A transmission gear is fixedly connected to the bottom of the fixing rod. A transmission rack is fixedly connected to the side surface of one of the rectangular rings. The top of the fixing rod penetrates through the dust suction box and extends into its interior and is fixedly connected with a rotating disk. An eccentric position on the top of the rotating disk is fixedly connected with a linkage pin. A traction frame is sleeved outside the linkage pin. A sealing plate is fixedly connected to the side surface of the traction frame. The bottom of the sealing plate is horizontally slidably connected to the bottom inner wall of the dust suction box, and a sliding seal contact is formed between the bottom of the sealing plate and the bottom inner wall of the dust suction box. A ventilation port horizontally staggered from the communication port is formed in the bottom of the sealing plate; during operation, when the rectangular ring moves downward along with the U-shaped plate, the transmission rack moves to one side of the transmission gear and contacts it. As the rectangular ring moves horizontally, the transmission rack is driven to move, and the fixing rod is driven to rotate through the contact between the transmission rack and the transmission gear. Thus, the fixing rod synchronously drives the rotating disk to rotate, and the rotating disk synchronously drives the linkage pin to move. The linkage pin reciprocally pushes the traction frame, and the traction frame synchronously drives the sealing plate to reciprocally move. During the process that the sealing plate drives the ventilation port to communicate with the communication port, the suction force generated by the vacuum cleaner generates a suction power at the dust suction head, thereby sucking the space between adjacent ultraviolet germicidal lamps, adsorbing the dust generated by the horizontal scraping, and timely sucking away the dust scraped and cleaned by the wiping cotton strip on the rectangular ring, avoiding secondary pollution to the non-woven fabric.

[0018] A sterilization method for a sterilization device used in non-woven fabric production and processing, the method comprising the following steps:

[0019] Step 1: Feed one end of the non-woven fabric into the processing cabinet along the feed port, transmit the non-woven fabric between the two conveying rollers through the cooperation of the conveying mechanism, and discharge it through the discharge port;

[0020] Step 2: During the transmission of the non-woven fabric, rotate and suck dust on the top of the non-woven fabric through the rotating plate, and deeply clean the interior of the fibers of the non-woven fabric through the multi-point jitter mechanism;

[0021] Step 3: Start ultraviolet sterilization to sterilize and disinfect the surface of the non-woven fabric during its transmission.

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

[0023] 1. The circular housing timely adsorbs the dust shaken up on the surface of the non-woven fabric and in the fibers through the circular through-hole on the surface of the rotating plate, and the dust enters the circular housing. Then, the dust in the circular housing is collected by the dust suction mechanism. During the movement of the dust-removed non-woven fabric, the surface of the non-woven fabric is sterilized by the irradiation of the ultraviolet germicidal lamp. The rotating plate rotates while adhering to the surface of the non-woven fabric to remove dust, and the multi-point shaking mechanism timely adsorbs the dust shaken out from the non-woven fabric fibers. On the one hand, it is beneficial to improve the cleaning effect of the non-woven fabric. On the other hand, it reduces the damage caused by knocking, reduces the degree of processing deformation of the non-woven fabric, prevents the non-woven fabric from vertically cracking along the fiber arrangement direction, and ensures the subsequent processing of the non-woven fabric.

[0024] 2. The rotating plate moves downward and approaches the top surface of the non-woven fabric. The contact roller contacts the top surface of the non-woven fabric and rotates along the top surface of the non-woven fabric during the rotation of the rotating plate. When the arc surface of the arc surface top block contacts the convex block during rotation, the arc surface top block moves downward, drives the U-shaped rod to move downward along the limit pin, and squeezes the fourth spring to cause the fourth spring to compress and deform. The U-shaped rod drives the contact roller to move downward and top the surface of the non-woven fabric, thereby causing the surface of the non-woven fabric to bulge. When the arc surface top block passes through the convex block, the elastic action of the fourth spring drives the U-shaped rod to move upward, and the U-shaped rod drives the contact roller to move upward, thereby canceling the bulging effect on the surface of the non-woven fabric. Thus, multi-point and multi-position bulging of the surface of the non-woven fabric is realized, and then the non-woven fabric is shaken. On the one hand, it can avoid the damage caused by single-point knocking. On the other hand, it can achieve large-area shaking, so that the dust inside the non-woven fabric is shaken out. And with the support of the contact roller, there is a space between the non-woven fabric and the rotating plate for the dust to float out and be sucked away.

[0025] 3. When the second motor starts to clean the dust on the non-woven fabric, the output shaft of the second motor drives the cam to rotate. The convex end of the cam squeezes the connecting frame, causing the rectangular ring to drive the plug pin to move along the sliding plug-in place and compress the fifth spring. When the convex end of the cam does not squeeze the connecting frame, the elastic action of the fifth spring makes the rectangular ring return to its original position, so that the rectangular ring continuously moves horizontally. During the movement, the wiping cotton strip on the rectangular ring repeatedly moves at the bottom of the lamp cover and cleans the surface of the lamp cover, thereby reducing the dust adhesion on the surface of the lamp cover and reducing the influence of dust on the sterilization of the ultraviolet germicidal lamp.

[0026] 4. The rotation of the fixed rod is driven by the contact between the transmission rack and the transmission gear. Consequently, the fixed rod synchronously drives the rotation of the rotating disc, and the rotating disc synchronously drives the movement of the linkage pin. The linkage pin reciprocally pushes the traction frame, and the traction frame synchronously drives the reciprocating movement of the sealing plate. During the process where the sealing plate drives the ventilation opening to communicate with the connecting port, the suction force generated by the vacuum cleaner will create a suction power at the suction head, thereby sucking the dust in the space between adjacent ultraviolet germicidal lamps. It can adsorb the dust generated by the horizontal scraping and promptly suck away the dust scraped and cleaned by the wiping cotton strip on the rectangular ring, avoiding secondary pollution to the non-woven fabric.

Detailed implementation manners

[0042] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0043] As Figures 2 - 11 shown, a sterilization device for non-woven fabric production and processing includes a processing cabinet 1. A cover plate 2 is fixedly connected to the top of the processing cabinet 1. A feeding port 3 and a discharging port 4 are respectively opened on both sides of the processing cabinet 1. Two first rotating shafts 5 are rotatably connected to one side of the processing cabinet 1 close to the discharging port 4. Conveying rollers 6 are fixedly connected to the first rotating shafts 5. One end of each of the two first rotating shafts 5 penetrates through one side of the processing cabinet 1 and extends to the outside of the processing cabinet 1 and then is fixedly connected with a mating gear 7. The mating gears 7 are meshed with each other. A first rotation driving mechanism is connected to the first rotating shaft 5;

[0044] A cooperating conveying mechanism is connected to the processing cabinet 1, and the cooperating conveying mechanism is used to transfer one end of the non-woven fabric between two conveying rollers 6;

[0045] Two hydraulic cylinders 8 are fixedly installed at the bottom of the cover plate 2. The bottom ends of the piston shafts of the two hydraulic cylinders 8 are commonly fixedly connected to a U-shaped plate 9. Both ends of the bottom of the U-shaped plate 9 are fixedly connected to circular shells 10. A dust suction mechanism is commonly communicated between the circular shells 10. An opening is formed at the bottom of the circular shell 10. A rotating plate 11 is rotatably connected to the opening at the bottom of the circular shell 10. A plurality of circular through holes 12 are formed in a circumferential array on the rotating plate 11. A second rotation driving mechanism for synchronously driving the two rotating plates 11 to rotate is connected to the side of the U-shaped plate 9. A multi-point jitter mechanism for cleaning the surface of the non-woven fabric is connected to each rotating plate 11;

[0046] A plurality of ultraviolet germicidal lamps 13 are fixedly connected to the bottom of the cover plate 2 in a linear array, and a lamp cover 14 is fixedly connected to the bottom of the ultraviolet germicidal lamp 13; during operation, in the prior art, during the sterilization of non-woven fabrics, the dust on the surface of the non-woven fabric is shaken off by means of physical hammering. Since the non-woven fabric belongs to a non-woven fabric and the fibers of the non-woven fabric are arranged in a certain direction, the non-woven fabric is prone to cracking from the right-angle direction during the physical hammering process, resulting in damage to the non-woven fabric and affecting the normal processing of the non-woven fabric. The technical solution of the present invention can solve the above problems. The specific working method is as follows: One end of the wound non-woven fabric is placed into the processing cabinet 1 from the feed port 3, and through the cooperation of the conveying mechanism, one end of the non-woven fabric is moved between the two conveying rollers 6. Then, under the action of the first rotation driving mechanism, one of the first rotating shafts 5 is driven to rotate. Through the meshing action of the two mating gears 7, the two first rotating shafts 5 rotate in opposite directions, and drive the two conveying rollers 6 to rotate in opposite directions, so that one end of the non-woven fabric passes between the two conveying rollers 6 and continuously conveys the non-woven fabric. During the transmission of the non-woven fabric inside the processing cabinet 1, two hydraulic cylinders 8 are started. The piston shaft of the hydraulic cylinder 8 drives the U-shaped plate 9 to move downward, so that the circular housing 10 moves downward. The circular housing 10 drives the rotating plate 11 to move downward, and the bottom of the rotating plate 11 is located on the top surface of the non-woven fabric. Through the action of the second rotation driving mechanism, the rotating plate 11 rotates on the top surface of the non-woven fabric, and through the action of the multi-point shaking mechanism, the top surface of the non-woven fabric is shaken regularly and intermittently at multiple points. On the one hand, the dust on the large area of the surface of the non-woven fabric can be shaken up by the slight convexity at multiple points and multiple positions, avoiding the pulling damage caused by single-point heavy beating. On the other hand, the dust suction mechanism sucks air into the inside of the circular housing 10. The circular housing 10 adsorbs the dust shaken up on the surface and in the fibers of the non-woven fabric in time through the circular through holes 12 on the surface of the rotating plate 11 and enters the circular housing 10. Then, the dust suction mechanism collects the dust in the circular housing 10. During the movement of the dust-removed non-woven fabric, the surface of the non-woven fabric is sterilized by the irradiation of the ultraviolet germicidal lamp 13. The rotating plate 11 rotates while adhering to the surface of the non-woven fabric for dust removal, and the multi-point shaking mechanism timely adsorbs the dust shaken out of the non-woven fabric fibers. On the one hand, it is beneficial to improve the cleaning effect of the non-woven fabric. On the other hand, it reduces the damage caused by beating, reduces the degree of processing deformation of the non-woven fabric, prevents the non-woven fabric from vertically cracking along the fiber arrangement direction, and ensures the subsequent processing of the non-woven fabric.

[0047] As an embodiment of the present invention, the first rotation driving mechanism includes a first motor 15 and two first pulleys 16. The first motor 15 is fixedly installed at the bottom of the processing cabinet 1. The two first pulleys 16 are respectively fixedly connected to the output shaft of the first motor 15 and one of the first rotating shafts 5. A first transmission belt 17 is connected between the first pulleys 16 for transmission. During operation, the rotation of the output shaft of the first motor 15 drives the first pulley 16 on the output shaft to rotate. Through the transmission of the first transmission belt 17, one of the first rotating shafts 5 is driven to rotate.

[0048] As an embodiment of the present invention, the cooperating conveying mechanism includes two chutes 18, which are respectively opened on both sides of the processing cabinet 1. Sliders 19 are slidably connected in the chutes 18. On one side of the sliders 19 located inside the processing cabinet 1, rectangular plates 20 are fixedly connected. Two circular rods 21 are fixedly connected between the two rectangular plates 20. Pressure rings 22 are sleeved on the circular rods 21. Two fixing pins 23 are fixedly connected to the inner walls of the pressure rings 22. The fixing pins 23 are slidably inserted into the adjacent circular rods 21. First springs 24 are sleeved on the fixing pins 23. The two ends of the first springs 24 are respectively fixedly connected to the circular rods 21 and the pressure rings 22. A positioning mechanism is connected to the sliders 19. During operation, one end of the non-woven fabric is placed into the processing cabinet 1 along the feeding port 3, and one end of the non-woven fabric is placed between the two pressure rings 22. The pressure rings 22 are squeezed by the elastic action of the first springs 24, so that the two pressure rings 22 approach each other and elastically clamp one end of the non-woven fabric. The sliders 19 are moved along the chutes 18 to make the sliders 19 approach the two conveying rollers 6 and the non-woven fabric is conveyed by the action of the conveying rollers 6. When one end of the non-woven fabric enters between the conveying rollers 6 and is conveyed, the sliders 19 are moved in the reverse direction to move the sliders 19 to one side of the feeding port 3, and then the position of the sliders 19 is positioned by the positioning mechanism, so that the part of the non-woven fabric located inside the processing cabinet 1 is elastically clamped by the two pressure rings 22 and remains in a taut state during the conveying process, which is convenient for dust suction and shaking of the surface of the non-woven fabric.

[0049] As an implementation manner of the present invention, the positioning mechanism includes a connecting block 25 and two rectangular bars 26. The connecting block 25 is fixedly connected to one side of the processing cabinet 1. Above the connecting block 25, there is a pull ring 27. At the bottom of the pull ring 27, two sliding pins 28 are fixedly connected. The bottom ends of the sliding pins 28 penetrate through the connecting block 25 and extend below the connecting block 25 and then are fixedly connected with arc-shaped stoppers 29. Second springs 30 are sleeved on the sliding pins 28. The two ends of the second springs 30 are respectively fixedly connected to the arc-shaped stoppers 29 and the connecting block 25. The two rectangular bars 26 are respectively fixedly connected to one side of the two sliders 19. One side of the arc-shaped stopper 29 is located on one side of one of the rectangular bars 26. During operation, by moving the rectangular bar 26 to drive the slider 19 to move. When the rectangular bar 26 moves to the side close to the feeding port 3, the top of the rectangular bar 26 contacts and presses against the arc-shaped guiding surface of the arc-shaped stopper 29, causing the arc-shaped stopper 29 to move upward and compressing the second spring 30 on the sliding pin 28, causing the second spring 30 to generate a compressive deformation. When the rectangular bar 26 passes through, the elastic action of the second spring 30 presses the arc-shaped stopper 29 to move in the reverse direction and blocks and positions the rectangular bar 26. When it is necessary to move the slider 19, pull up the pull ring 27 upward, and the arc-shaped stopper 29 can be moved upward to move the rectangular bar 26.

[0050] As an implementation manner of the present invention, the dust suction mechanism includes a dust collector 31 and a U-shaped pipe 32. The dust collector 31 is fixedly installed on the top of the cover plate 2. The U-shaped pipe 32 is located above the two circular shells 10. The two ends of the U-shaped pipe 32 are respectively fixedly communicated with the tops of the two circular shells 10. The dust suction end of the dust collector 31 is fixedly communicated with a telescopic pipe 33. The end of the telescopic pipe 33 away from the dust collector 31 penetrates through the cover plate 2 and extends below it and then is fixedly communicated with the U-shaped pipe 32. During operation, by starting the dust collector 31, due to the communication effect of the telescopic pipe 33 and the U-shaped pipe 32, a negative pressure is generated in the two circular shells 10, so that the rotating plate 11 adsorbs the dust on the non-woven fabric through the circular through hole 12, and the dust located in the circular shell 10 enters the dust collector 31 along the U-shaped pipe 32 and the telescopic pipe 33 for collection.

[0051] As an implementation manner of the present invention, the second rotation driving mechanism includes a second motor 34 and two second rotating shafts 35. The second motor 34 is fixedly connected to one side of the U-shaped plate 9. The two second rotating shafts 35 are respectively fixedly connected to the tops of the two rotating plates 11. The tops of the second rotating shafts 35 penetrate through the adjacent circular shells 10 and extend above the circular shells 10 and are fixedly connected with second belt pulleys 36. A third belt pulley 37 is fixedly connected to the output shaft of the second motor 34. The third belt pulley 37 and the two second belt pulleys 36 are driven by a second transmission belt 38. The tops of the circular shells 10 are rotatably connected with abutting pins 39, and the abutting pins 39 are in contact with the side surfaces of the second transmission belt 38. During operation, by starting the second motor 34, the output shaft of the second motor 34 drives the third belt pulley 37 to rotate, and drives the two second belt pulleys 36 to rotate through the transmission of the second transmission belt 38, so that the two second rotating shafts 35 rotate, driving the rotating plates 11 to rotate. By arranging two abutting pins 39 on the side surface of the second transmission belt 38, the second transmission belt 38 is in a tensioned state, ensuring the transmission effect of the second transmission belt 38, and the rotation of the abutting pins 39 makes the contact between the abutting pins 39 and the side surface of the second transmission belt 38 a rolling friction, reducing the friction force and the wear on the side surface of the second transmission belt 38.

[0052] As an embodiment of the present invention, the multi-point jitter mechanism includes a plurality of rectangular through slots 40 and convex blocks 41. The rectangular through slots 40 are arranged in a circumferential array on the rotating plate 11. Contact rollers 42 are placed in each of the rectangular through slots 40. U-shaped rods 43 are rotatably connected to the contact rollers 42. The U-shaped rods 43 are all located inside the circular housing 10. Two limit pins 44 are slidably inserted into each of the U-shaped rods 43. The bottom ends of the limit pins 44 are fixedly connected to the top of the rotating plate 11. A fourth spring 45 is sleeved on each of the limit pins 44. Arc-shaped top blocks 46 are fixedly connected to the tops of the U-shaped rods 43. The convex blocks 41 are fixedly connected to the top surface inside the circular housing 10 in a circumferential array. During operation, the rotating plate 11 moves downward and approaches the top surface of the non-woven fabric. The contact rollers 42 come into contact with the top surface of the non-woven fabric and rotate along the top surface of the non-woven fabric during the rotation of the rotating plate 11. When the arc-shaped surface of the arc-shaped top block 46 comes into contact with the convex block 41 during rotation, the arc-shaped top block 46 moves downward, driving the U-shaped rod 43 to move downward along the limit pin 44 and squeezing the fourth spring 45 to cause it to compress and deform. The U-shaped rod 43 drives the contact roller 42 to move downward and make a top contact with the surface of the non-woven fabric, thereby causing the surface of the non-woven fabric to bulge. When the arc-shaped top block 46 passes through the convex block 41, the elastic action of the fourth spring 45 drives the U-shaped rod 43 to move upward, and the U-shaped rod 43 drives the contact roller 42 to move upward, thus canceling the bulging effect on the surface of the non-woven fabric. Furthermore, multi-point and multi-position bulging of the surface of the non-woven fabric is achieved, and then the non-woven fabric is caused to jitter. On the one hand, damage caused by single-point knocking can be avoided. On the other hand, large-area jitter can be realized, so that the dust inside the non-woven fabric is shaken out. And with the support of the contact rollers 42, a space can be left between the non-woven fabric and the rotating plate 11 for the dust to float out and be sucked away.

[0053] As an embodiment of the present invention, rectangular rings 47 are sleeved on the tops of the lamp covers 14. Two connecting rods 48 are fixedly connected between adjacent rectangular rings 47. One side of the top of each rectangular ring 47 is fixedly installed with a wiping cotton strip 49. Two plug pins 50 are fixedly connected to one side of the rectangular ring 47 close to the U-shaped plate 9. The plug pins 50 are slidably inserted into the U-shaped plate 9. Fifth springs 51 are sleeved on the plug pins 50. The two ends of each fifth spring 51 are fixedly connected to the rectangular ring 47 and the U-shaped plate 9 respectively. A cam 52 is fixedly connected to the surface of the output shaft of the second motor 34. A connecting frame 53 is fixedly connected to the bottom of the rectangular ring 47 close to the U-shaped plate 9. The cam 52 is located inside the connecting frame 53. During operation, when the rotating plate 11 cleans and adsorbs dust on the surface of the non-woven fabric, some unadsorbed dust flutters in the processing cabinet 1 and adheres to the surface of the lamp cover 14, thus blocking the light source of the ultraviolet germicidal lamp 13 and affecting the sterilization effect. By connecting the rectangular ring 47 and the U-shaped plate 9 through the plug pins 50, when the U-shaped plate 9 moves downward through the hydraulic cylinder 8, the rectangular ring 47 moves downward together with the U-shaped plate 9 and is located below the lamp cover 14. When the U-shaped plate 9 moves downward, the rectangular ring 47 moves to the top of the lamp cover 14, so that it will not affect the light projection of the lamp cover 14. When the second motor 34 is started to clean the dust on the non-woven fabric, the output shaft of the second motor 34 drives the cam 52 to rotate. The protruding end 5201 of the cam 52 presses the connecting frame 53, causing the rectangular ring 47 to drive the plug pins 50 to move along the sliding insertion part, and causing the fifth spring 51 to generate a compressive deformation. When the protruding end 5201 of the cam 52 does not press the connecting frame 53, the elastic action of the fifth spring 51 causes the rectangular ring 47 to return to its original position, so that the rectangular ring 47 continuously moves horizontally. During the movement, the wiping cotton strip 49 on the rectangular ring 47 repeatedly moves at the bottom of the lamp cover 14 and cleans the surface of the lamp cover 14, thereby reducing the dust adhesion on the surface of the lamp cover 14 and reducing the influence of dust on the sterilization of the ultraviolet germicidal lamp 13.

[0054] As an implementation manner of the present invention, a dust suction box 54 is fixedly connected to the bottom of the cover plate 2. A dust suction pipe 55 is fixedly connected to the top of the dust suction box 54. One end of the dust suction pipe 55 away from the dust suction box 54 penetrates through the cover plate 2 and is fixedly communicated with the dust suction end of the vacuum cleaner 31. A plurality of communication ports 63 are opened at the bottom of the dust suction box 54. The communication ports 63 are located at positions between two adjacent ultraviolet germicidal lamps 13. A dust suction head 57 is fixedly communicated with the opening of the dust suction box 54 corresponding to the communication port 63. A fixing rod 59 is rotatably connected to the bottom of the dust suction box 54. A transmission gear 60 is fixedly connected to the bottom of the fixing rod 59. A transmission rack 61 is fixedly connected to the side surface of one of the rectangular rings 47. The top of the fixing rod 59 penetrates through the dust suction box 54 and extends into its interior and is fixedly connected with a rotating disk 64. An eccentric position on the top of the rotating disk 64 is fixedly connected with a linkage pin 65. A traction frame 66 is sleeved outside the linkage pin 65. A sealing plate 58 is fixedly connected to the side surface of the traction frame 66. The bottom of the sealing plate 58 is horizontally slidably connected to the bottom of the inner wall of the dust suction box 54, and there is a sliding seal contact between the bottom of the sealing plate 58 and the bottom of the inner wall of the dust suction box 54. A ventilation port 62 which is horizontally staggered from the communication port 63 is opened at the bottom of the sealing plate 58; during operation, when the rectangular ring 47 moves downward along with the U-shaped plate 9, the transmission rack 61 moves to one side of the transmission gear 60 and contacts it. As the rectangular ring 47 moves horizontally to drive the transmission rack 61 to move, and the contact between the transmission rack 61 and the transmission gear 60 drives the fixing rod 59 to rotate. Thus, the fixing rod 59 synchronously drives the rotating disk 64 to rotate, and the rotating disk 64 synchronously drives the linkage pin 65 to move. The linkage pin 65 reciprocally pushes the traction frame 66, and the traction frame 66 synchronously drives the sealing plate 58 to reciprocally move. During the process that the sealing plate 58 drives the ventilation port 62 to communicate with the communication port 63, the suction force generated by the vacuum cleaner 31 will generate a suction power at the dust suction head 57, thereby sucking the space between two adjacent ultraviolet germicidal lamps 13, adsorbing the dust generated by the horizontal scraping, and timely sucking away the dust scraped and cleaned by the wiping cotton strip 49 on the rectangular ring 47, avoiding secondary pollution to the non-woven fabric.

[0055] As Figure 1 shown, a sterilization method for a sterilization device for non-woven fabric production and processing includes the following steps:

[0056] Step 1: Feed one end of the non-woven fabric into the processing cabinet 1 along the feed port 3, transmit the non-woven fabric between two conveying rollers 6 through the cooperation of the conveying mechanism, and discharge it through the discharge port 4;

[0057] Step 2: During the transmission of the non-woven fabric, rotate and suck dust on the top of the non-woven fabric through the rotating plate 11, and deeply clean the interior of the fibers of the non-woven fabric through the multi-point jitter mechanism;

[0058] Step 3: Start the ultraviolet sterilization so that the non-woven fabric is sterilized on the surface during the transmission process.

[0059] Working principle of the present invention:

[0060] During operation, in the prior art, during the sterilization of the non-woven fabric, the dust on the surface of the non-woven fabric is shaken off by means of physical hammering. Since the non-woven fabric belongs to a non-woven fabric and the fibers of the non-woven fabric are arranged in a certain direction, during the process of being physically hammered, the non-woven fabric is prone to cracking from the right-angle direction, resulting in damage to the non-woven fabric and affecting the normal processing of the non-woven fabric. This technical solution can solve the above problems. The specific working method is as follows: One end of the wound non-woven fabric is placed into the processing cabinet 1 from the feed port 3, and one end of the non-woven fabric is moved between the two conveying rollers 6 through the cooperation of the conveying mechanism. Then, under the action of the first rotation driving mechanism, one of the first rotating shafts 5 is driven to rotate. The two first rotating shafts 5 rotate in opposite directions through the meshing action of the two mating gears 7, and drive the two conveying rollers 6 to rotate in opposite directions, so that one end of the non-woven fabric passes between the two conveying rollers 6 and the non-woven fabric is continuously conveyed. During the transmission of the non-woven fabric inside the processing cabinet 1, two hydraulic cylinders 8 are started. The piston shaft of the hydraulic cylinder 8 drives the U-shaped plate 9 to move downward, so that the circular housing 10 moves downward. The circular housing 10 drives the rotating plate 11 to move downward, and the bottom of the rotating plate 11 is located on the top surface of the non-woven fabric. Under the action of the second rotation driving mechanism, the rotating plate 11 rotates on the top surface of the non-woven fabric, and through the action of the multi-point shaking mechanism, the top surface of the non-woven fabric is shaken regularly and intermittently at multiple points. On the one hand, the dust on the large area of the surface of the non-woven fabric can be shaken up by the slight protrusions at multiple points and multiple positions, avoiding the pulling damage caused by single-point heavy knocking. On the other hand, the dust suction mechanism sucks air into the inside of the circular housing 10. The circular housing 10 adsorbs the dust shaken up from the surface and fibers of the non-woven fabric in a timely manner through the circular through holes 12 on the surface of the rotating plate 11 and enters the circular housing 10. Then, the dust suction mechanism collects the dust in the circular housing 10. During the movement of the dust-removed non-woven fabric, the surface of the non-woven fabric is sterilized by the irradiation of the ultraviolet sterilization lamp 13. The rotating plate 11 rotates while fitting on the surface of the non-woven fabric to remove dust, and the multi-point shaking mechanism timely adsorbs the dust shaken out from the fibers of the non-woven fabric. On the one hand, it is beneficial to improve the cleaning effect of the non-woven fabric. On the other hand, it reduces the damage caused by knocking, reduces the degree of processing deformation of the non-woven fabric, prevents the non-woven fabric from vertically cracking along the fiber arrangement direction, and ensures the subsequent processing of the non-woven fabric.

[0061] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
