Description

Technical Field

[0001] This invention relates to the field of sterilization technology, specifically to a sterilization equipment and method for the production and processing of antibacterial nonwoven fabrics. Background Technology

[0002] Nonwoven fabric is a type of nonwoven 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 nonwoven fabric. After production, nonwoven fabric needs to be sterilized and stored using methods such as steam or high temperature to extend its storage time.

[0003] Existing sterilization equipment for finished nonwoven fabrics typically sterilizes them by high temperatures, directly spreading them out in a cylindrical or square box and heating them for a period of time. This heating sterilization method is inefficient and may even result in the bottom surface not being fully heated. In addition, the existing nonwoven fabric sterilization and slitting processes are carried out separately, which reduces work efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a sterilization device for the production and processing of antibacterial nonwoven fabric, comprising a pull roller and a heater, wherein the pull roller is disposed beside the heater, the pull roller includes a side support plate, a fixed shaft is fixedly connected to the inner side of the side support plate, a center roller is fixedly connected to the outer side of the fixed shaft, side frames are fixedly connected to both ends of the side support plate, an emergency stop lever is inserted into the top of the side frame, and the bottom of the emergency stop lever is inserted into the interior of the side support plate;

[0005] The center roller is symmetrically provided with grooved plates on both sides. The grooved plates are rotatably mounted on the outside of the fixed shaft. A sliding shaft is slidably mounted on the inside of the grooved plates. An expander is fixedly connected to the end of the sliding shaft away from the grooved plates. A stacked plate is provided on the outside of the expander. The stacked plate is fixedly connected to the sliding shaft. A cutter is fixedly connected to the outside of the stacked plate.

[0006] A second cutter is rotatably mounted on the outside of the fixed shaft, and a flow divider is provided below the fixed shaft. The flow divider is fixedly installed on the inside of the side support plate. First, the non-woven fabric is placed on the top of the central roller and then moved on its surface. Next, the non-woven fabric is allowed to pass through the position between the first cutter and the expander, and then through the flow divider and the second cutter, and finally enters the heater for heating and sterilization.

[0007] The heater includes a housing, inside which a first winding roller and a second winding roller are fixedly connected respectively. A heating assembly is fixedly installed on the top of the housing, and an regulator is fixedly connected to the bottom of the heating assembly. The regulator is fixedly installed inside the housing.

[0008] Preferably, the distributor includes a cross plate, the end face of which is fixedly connected to a side support plate. A lead screw is sleeved on the inner side of the cross plate, and a slide rod is threadedly connected to the outer side of the lead screw. A bottom roller is fixedly connected to the outer side of the slide rod, and a uniform scraping plate is fixedly connected to the outer side of the bottom roller. The top end of the uniform scraping plate is fixedly connected to the cross plate. Since the outer side of the slide rod is fixedly connected to the bottom roller, and the uniform scraping plate is fixedly connected to the outer side of the bottom roller, the downward-moving uniform scraping plate effectively evenly distributes the disinfectant solution onto the surface of the non-woven fabric.

[0009] Preferably, a traction strip is fixedly connected to the inner side of the side support plate. A first bridge-shaped plate is fixedly connected to the end of the traction strip away from the side support plate. A second bridge-shaped plate is positioned above the first bridge-shaped plate, with both ends of the second bridge-shaped plate fixedly connected to the side support plate. A pressure head is fitted onto the top of the second bridge-shaped plate. The non-woven fabric passes through the space formed by the first bridge-shaped plate and the second bridge-shaped plate. At this point, the top of the non-woven fabric near the edge is squeezed downwards by the pressure head, and the middle part of the non-woven fabric forms a bridge-shaped posture—that is, a convex center and concave ends—so that the disinfectant sprayed onto the non-woven fabric can be distributed on both sides.

[0010] Preferably, the first cutter includes an iron plate, the outer side of which is fixedly connected to the stacked plate, a protective cover is provided on the side of the plate, and an inner rod is fixedly installed inside the plate.

[0011] Preferably, a one-way seat is fixedly connected to the top of the inner rod, a cutter is fixedly connected inside the one-way seat, a magnet is fixedly connected to the bottom side of the cutter, a magnetic column is disposed below the cutter, the magnetic column is slidably installed inside the adhesive plate, and an electromagnet is fixedly connected to the bottom of the magnetic column. When the magnetic column is adjusted to an attractive force, the magnetic column will attract the magnet fixed to the bottom side of the cutter, causing the cutter to deflect to the lower left, thereby cutting the non-woven fabric attached and sliding on the expander.

[0012] Preferably, the expander includes an expander housing, both ends of which are fixedly connected to a sliding shaft. A spring bar is fixedly connected to the inner side of the expander housing. A support column is fixedly connected to the end of the spring bar away from the expander housing. A central disk is fixedly connected to the end of the support column away from the spring bar. Both ends of the central disk are fixedly connected to tapered studs.

[0013] Preferably, a rotator is fixedly connected to the end of the conical stud away from the central disc. A limiting plate is rotatably mounted on the outer side of the rotator, and a conical spring is fixedly connected to the outer side of the limiting plate. The expansion shell expands outward due to its elasticity, stretching the nonwoven fabric attached to and sliding on its surface. Then, the rotator is reversed, restoring the mechanism to its initial state. The nonwoven fabric then contracts and returns to its initial state, ultimately achieving the effect of expanding and stretching the nonwoven fabric.

[0014] Preferably, an elastic block is fixedly connected to one end of the conical spring away from the limiting plate, and an expansion sleeve is fixedly connected to the outer side of the elastic block. The outer side of the expansion sleeve is threadedly connected to the surface of the conical stud.

[0015] Preferably, the regulator includes a through-hole ring, the top of which is fixedly connected to the heating assembly, and a sliding groove is provided inside the through-hole ring, with a folding baffle slidably installed on the inner side of the sliding groove.

[0016] Preferably, a bimetallic strip is fixedly connected to the bottom of the folding baffle, and a locking block is fixedly connected to the end of the bimetallic strip away from the folding baffle. A stop plate is fixedly connected to the bottom of the locking block, and the top of the stop plate is fixedly connected to the outer shell. When the temperature inside the outer shell is too high, the bimetallic strip will bend. The other end of the bimetallic strip is connected to the folding baffle, which is foldable. Therefore, the originally folded baffle will open outward along the slide groove. At this time, the flow hole between the heating component and the outer shell will be reduced, thereby reducing the heat flow.

[0017] A sterilization method for the production and processing of antibacterial nonwoven fabrics includes the following steps:

[0018] Step 1: Stretching and expansion. When the expansion sleeve moves to the leftmost end of the limiting plate, the conical spring is already compressed in the space enclosed by the expansion sleeve and the limiting plate. At the same time, the maximum cross-sectional area of ​​the expansion sleeve has exceeded the initial cross-sectional area of ​​the expansion shell. Therefore, the expansion shell will expand outward due to its own elasticity, and the non-woven fabric attached to and sliding on its surface will be stretched accordingly.

[0019] Step 2: Cutting into segments. Activate the electromagnet to achieve magnetic control of each magnetic column. When the magnetic column is adjusted to an attractive force, it will attract the magnet fixed to the bottom of the cutter, causing the cutter to deflect to the lower left. At this time, the cutter will cut the non-woven fabric attached to and sliding on the expander.

[0020] Step 3: Disinfection evenly. The non-woven fabric passes through the space formed by the first bridge plate and the second bridge plate. At this time, the top of the non-woven fabric near the edge will be squeezed downward by the pressure head. At the same time, the middle part of the non-woven fabric will form a bridge shape, that is, the center is raised and the two ends are concave. This will cause the disinfectant water that was originally accumulated in the center of the non-woven fabric to be distributed on both sides.

[0021] Step 4: Heating and sterilization. When the temperature inside the outer shell is too high, the bimetallic strip fixed on the card block will bend towards the center of the through-hole ring. The other end of the bimetallic strip is connected to the folding baffle. The folding baffle is foldable, so the folding baffle, which was originally folded together, will open outward along the slide. At this time, the hole between the heating component and the outer shell will be reduced.

[0022] This invention provides a sterilization device and method for the production and processing of antibacterial nonwoven fabrics. It possesses the following features:

[0023] Beneficial effects:

[0024] I. The sterilization equipment and method for the production and processing of antibacterial nonwoven fabric involves the nonwoven fabric passing through the space formed by the first bridge plate and the second bridge plate. At this time, the top of the nonwoven fabric near the edge is squeezed downward by the pressure head, and the middle part of the nonwoven fabric forms a bridge shape, that is, the center is convex and the two ends are concave, so that the disinfectant sprayed on the nonwoven fabric can be distributed on both sides.

[0025] II. The sterilization equipment and method for the production and processing of antibacterial nonwoven fabric involves rotating a lead screw, which causes a slide rod connected to it to move downwards. The outer side of the slide rod is fixedly connected to a bottom roller, and a uniform scraping plate is fixedly connected to the outer side of the bottom roller. Therefore, the downward-moving uniform scraping plate plays the role of uniformly scraping the disinfectant on the surface of the nonwoven fabric.

[0026] III. The sterilization equipment and method for the production and processing of antibacterial nonwoven fabrics achieve magnetic control of each magnetic column by activating an electromagnet. When the magnetic column is adjusted to an adsorption force, the magnetic column will attract the magnet fixed on the bottom side of the cutter, causing the cutter to deflect to the lower left, thereby cutting the nonwoven fabric attached to and sliding on the expander.

[0027] IV. The sterilization equipment and method for the production and processing of antibacterial nonwoven fabrics, by means of the expansion sleeve having a maximum cross-sectional area exceeding the initial cross-sectional area of ​​the expansion shell, the expansion shell will expand outward due to its own elasticity, and the nonwoven fabric attached to and sliding on its surface will be stretched accordingly. Then the self-rotator is reversed, so that the above mechanism returns to its initial state. At this time, the nonwoven fabric will shrink and return to its initial state, ultimately achieving the effect of expanding and stretching the nonwoven fabric.

[0028] V. The sterilization equipment and sterilization method for the production and processing of antibacterial nonwoven fabrics utilizes the folding baffle, which is foldable. Therefore, the folding baffle, which was originally folded together, will open outward along the slide groove. At this time, the flow hole between the heating component and the outer shell will be reduced, thereby reducing the heat flow and lowering the internal temperature of the outer shell. When the internal temperature of the outer shell returns to its original state or decreases, the bimetallic strip will automatically return to its original position. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0040] First embodiment, such as Figures 1-7 As shown, the present invention provides a technical solution: a sterilization device and sterilization method for the production and processing of antibacterial nonwoven fabrics, including a pull roller 1 and a heater 2, wherein the pull roller 1 is disposed on the side of the heater 2.

[0041] The roller puller 1 includes a side support plate 11. A fixed shaft 12 is fixedly connected to the inner side of the side support plate 11, and a center roller 13 is fixedly connected to the outer side of the fixed shaft 12. Side frames 14 are fixedly connected to both ends of the side support plate 11. An emergency stop lever 15 is inserted into the top of the side frame 14, and the bottom of the emergency stop lever 15 is inserted into the interior of the side support plate 11. Grooves 16 are symmetrically arranged on both sides of the center roller 13. The grooves 16 are rotatably mounted on the outer side of the fixed shaft 12. A sliding shaft 17 is slidably installed on the inner side of the 6. An expander 18 is fixedly connected to the end of the sliding shaft 17 away from the trough plate 16. A stacking plate 19 is provided on the outer side of the expander 18. The stacking plate 19 is fixedly connected to the sliding shaft 17. A first cutter 10 is fixedly connected to the outer side of the stacking plate 19. A second cutter 112 is rotatably installed on the outer side of the fixed shaft 12. A diverter 110 is provided below the fixed shaft 12. The diverter 110 is fixedly installed on the inner side of the side support plate 11. First, the nonwoven fabric is placed on the top of the central roller 13 and then moved on its surface. Then, the nonwoven fabric passes through the position between the first cutter 10 and the expander 18, and then passes through the diverter 110 and the second cutter 112 respectively, and finally enters the heater 2 for heating and sterilization.

[0042] The distributor 110 includes a cross plate 1101, the end face of which is fixedly connected to a side support plate 11. A lead screw 1102 is sleeved on the inner side of the cross plate 1101, and a slide rod 1103 is threadedly connected to the outer side of the lead screw 1102. A bottom roller 1104 is fixedly connected to the outer side of the slide rod 1103, and a leveling plate 1109 is fixedly connected to the outer side of the bottom roller 1104. The top end of the leveling plate 1109 is connected to... A cross plate 1101 is fixedly connected. A traction strip 1105 is fixedly connected to the inner side of the side support plate 11. A first bridge plate 1106 is fixedly connected to one end of the traction strip 1105 away from the side support plate 11. A second bridge plate 1107 is provided above the first bridge plate 1106. Both ends of the second bridge plate 1107 are fixedly connected to the side support plate 11. A pressure head 1108 is sleeved on the top of the second bridge plate 1107. The non-woven fabric passes through the space formed by the first bridge plate 1106 and the second bridge plate 1107. At this time, the top of the non-woven fabric near the edge is squeezed downward by the pressure head 1108. At the same time, the middle part of the non-woven fabric forms a bridge-shaped posture, that is, a state with a convex center and concave ends. This allows the disinfectant sprayed on the non-woven fabric to be distributed on both sides, since most of the disinfectant sprayed was sprayed on the center of the non-woven fabric.

[0043] Then, the lead screw 1102 is rotated, causing the slide bar 1103, which is threaded to it, to move downward. The outer side of the slide bar 1103 is fixedly connected to the bottom roller 1104, and the outer side of the bottom roller 1104 is fixedly connected to the equalizing plate 1109. Therefore, the downward moving equalizing plate 1109 plays the role of evenly distributing disinfectant on the surface of the nonwoven fabric. In addition, this operation is performed after the previous operation.

[0044] The first cutter 10 includes an iron plate 101, the outer side of which is fixedly connected to the stacked plate 19. A protective cover 105 is provided on the side of the plate 101. An inner rod 108 is fixedly installed inside the plate 101. A one-way seat 102 is fixedly connected to the top of the inner rod 108. A cutter 103 is fixedly connected inside the one-way seat 102. A magnet 104 is fixedly connected to the bottom side of the cutter 103. A magnetic column 107 is provided below the cutter 103. The magnetic column 107 is slidably installed inside the plate 101. An electromagnet 106 is fixedly connected to the bottom of the magnetic column 107. When the nonwoven fabric passes through the first cutter 10 and the expander 18, the nonwoven fabric is always attached to the expander 18. Then, the electromagnet 106 is moved upward, so that the magnetic column 107 connected to it moves upward along the inside of the plate 101. The electromagnet 106 is then activated to achieve magnetic control of each magnetic column 107. When the magnetic column 107 is adjusted to an adsorption force, the magnetic column 107 will attract the magnet 104 fixed on the bottom side of the cutter 103, so that the cutter 103 will deflect to the lower left, thereby cutting the nonwoven fabric attached to and sliding on the expander 18.

[0045] When the magnetic post 107 is adjusted to exert a repulsive force, it repels the magnet 104, causing the cutter 103 to deflect to the right until it reaches a vertical position. The cutter 103 deflects via the one-way seat 102, which restricts its degree of freedom, allowing it to rotate only in one direction. The cutter 103 reaches its position limit when it rotates to the right and reaches a vertical position. A protective cover 105 then covers it for protection.

[0046] The expander 18 includes an expander shell 181, both ends of which are fixedly connected to a sliding shaft 17. A spring bar 182 is fixedly connected to the inner side of the expander shell 181. A support column 183 is fixedly connected to the end of the spring bar 182 away from the expander shell 181. A central disk 184 is fixedly connected to the end of the support column 183 away from the spring bar 182. Tapered studs 187 are fixedly connected to both ends of the central disk 184. A rotator 180 is fixedly connected to the end of the tapered stud 187 away from the central disk 184. A limiting plate 189 is rotatably mounted on the outer side of the rotator 180. A tapered spring 188 is fixedly connected to the outer side of the limiting plate 189. An elastic block 186 is fixedly connected to the end of the tapered spring 188 away from the limiting plate 189. An expansion sleeve 185 is fixedly connected to the outer side of the elastic block 186. The outer side of the expansion sleeve 185 is threaded onto the surface of the tapered stud 187. The rotator 180, which is fixedly installed inside the expansion housing 181, is activated, causing the limiting plate 189 fixed on its outer side to rotate forward. The limiting plate 189 is connected to the conical spring 188, and the other end of the conical spring 188 is connected to the elastic block 186, which is installed inside the expansion sleeve 185. Therefore, the expansion sleeve 185 will also rotate forward, causing the expansion sleeve 185, which is threaded onto the conical stud 187, to move to the right. When the conical spring 188 rotates forward, it is not only compressed by the expansion sleeve 185, but its cross-sectional area also increases. However, the maximum range of expansion deformation of the conical spring 188 will not exceed the height of the limiting plate 189.

[0047] As the expansion sleeve 185 moves to the right, its body also increases because it is threaded onto the conical stud 187. The expansion sleeve 185 and the elastic block 186 are elastic. When the expansion sleeve 185 moves to the leftmost end of the limiting piece 189, the conical spring 188 is compressed within the space enclosed by the expansion sleeve 185 and the limiting piece 189. At the same time, the maximum cross-sectional area of ​​the expansion sleeve 185 exceeds the initial cross-sectional area of ​​the expansion shell 181. Therefore, the expansion shell 181 will expand outward due to its own elasticity, and the nonwoven fabric attached to and sliding on its surface will be stretched. Then, the rotator 180 is reversed, so that the above mechanism returns to its initial state. At this time, the nonwoven fabric will contract and return to its initial state, ultimately achieving the effect of expanding and stretching the nonwoven fabric.

[0048] Second embodiment, such as Figures 8-9 As shown, the heater 2 includes a housing 21, with a first winding roller 22 and a second winding roller 23 fixedly connected inside the housing 21. A heating assembly 25 is fixedly installed on the top of the housing 21, and an regulator 24 is fixedly connected to the bottom of the heating assembly 25. The regulator 24 is fixedly installed inside the housing 21.

[0049] The regulator 24 includes a through-hole ring 241, the top of which is fixedly connected to the heating assembly 25. A groove 242 is formed inside the through-hole ring 241, and a folding baffle 243 is slidably mounted on the inner side of the groove 242. A bimetallic strip 244 is fixedly connected to the bottom of the folding baffle 243, and a locking block 245 is fixedly connected to the end of the bimetallic strip 244 away from the folding baffle 243. A stop plate 246 is fixedly connected to the bottom of the locking block 245, and the top of the stop plate 246 is fixedly connected to the outer shell 21. The nonwoven fabric that finally enters the outer shell 21 will move in an S-shaped manner, overlapping the first winding roller 22 and the second winding roller 23 respectively, thereby increasing the heating area of ​​the nonwoven fabric.

[0050] The heating component 25 is then activated, allowing hot air to enter the outer casing 21 for secondary high-temperature sterilization of the non-woven fabric. When the temperature inside the outer casing 21 is too high, the bimetallic strip 244, which is fixedly installed on the clip 245, will bend towards the center of the through-hole ring 241. The other end of the bimetallic strip 244 is connected to the folding baffle 243, which is foldable. Therefore, the folding baffle 243, which was originally folded, will open outward along the slide groove 242. At this time, the flow hole between the heating component 25 and the outer casing 21 will be reduced, thereby reducing the heat flow and lowering the temperature inside the outer casing 21. When the temperature inside the outer casing 21 returns to its original state or decreases, the bimetallic strip 244 will automatically return to its original position.

[0051] A sterilization method for the production and processing of antibacterial nonwoven fabrics includes the following steps:

[0052] Step 1: Stretch and expand. When the expansion sleeve 185 moves to the leftmost end of the limiting piece 189, the conical spring 188 is already compressed in the space enclosed by the expansion sleeve 185 and the limiting piece 189. At the same time, the maximum cross-sectional area of ​​the expansion sleeve 185 has exceeded the initial cross-sectional area of ​​the expansion shell 181. Therefore, the expansion shell 181 will expand outward due to its own elasticity, and the non-woven fabric attached to and sliding on its surface will be stretched as a result.

[0053] Step 2: Cutting into segments. Activate the electromagnet 106 to achieve magnetic control of each magnetic post 107. When the magnetic post 107 is adjusted to an attractive force, the magnetic post 107 will attract the magnet 104 fixed to the bottom side of the cutter 103, causing the cutter 103 to deflect to the lower left. At this time, the cutter will cut the non-woven fabric attached to and sliding on the expander 18.

[0054] Step 3: Disinfection is uniform. The non-woven fabric passes through the space formed by the first bridge plate 1106 and the second bridge plate 1107. At this time, the top of the non-woven fabric near the edge will be squeezed downward by the pressure head 1108. At the same time, the middle part of the non-woven fabric will form a bridge shape, that is, the center is raised and the two ends are concave, so that the disinfectant water that was originally accumulated in the center of the non-woven fabric will be distributed on both sides.

[0055] Step 4: Heating and sterilization. When the temperature inside the outer shell 21 is too high, the bimetallic strip 244 fixedly installed on the clip 245 will bend towards the center of the through hole ring 241. The other end of the bimetallic strip 244 is connected to the folding baffle 243, which is foldable. Therefore, the folding baffle 243, which was originally folded together, will open outward along the slide groove 242. At this time, the hole between the heating component 25 and the outer shell 21 will be reduced.

[0056] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.

6. The sterilization equipment for the production and processing of antibacterial nonwoven fabrics according to claim 1, characterized in that: The regulator (24) includes a through-hole ring (241), the top of which is fixedly connected to the heating assembly (25). A sliding groove (242) is provided inside the through-hole ring (241), and a folding baffle (243) is slidably installed on the inner side of the sliding groove (242).

7. A sterilization method for the production and processing of antibacterial nonwoven fabrics, characterized in that: Includes the following steps: Step 1: Stretch and expand. When the expansion sleeve (185) moves to the leftmost end of the limiting piece (189), the conical spring (188) is already compressed in the space enclosed by the expansion sleeve (185) and the limiting piece (189). At the same time, the maximum cross-sectional area of ​​the expansion sleeve (185) has exceeded the initial cross-sectional area of ​​the expansion shell (181). Therefore, the expansion shell (181) will expand outward due to its own elasticity, and the non-woven fabric attached to and sliding on its surface will be stretched accordingly. Step 2: Cutting into segments. Start the electromagnet (106) to achieve magnetic control of each magnetic column (107). When the magnetic column (107) is adjusted to an adsorption force, the magnetic column (107) will attract the magnet (104) fixed on the bottom side of the cutter (103), causing the cutter (103) to deflect to the lower left. At this time, the cutter will cut the non-woven fabric attached to the slide on the expander (18). Step 3: Disinfection is uniform. The non-woven fabric passes through the space formed by the first bridge plate (1106) and the second bridge plate (1107). At this time, the top of the non-woven fabric near the edge will be squeezed downward by the pressure head (1108). At the same time, the middle part of the non-woven fabric will form a bridge shape, that is, the center is raised and the two ends are concave, so that the disinfectant water that was originally accumulated in the center of the non-woven fabric will be distributed on both sides. Step 4: Heating and sterilization. When the temperature inside the outer shell (21) is too high, the bimetallic strip (244) fixed on the card block (245) will bend toward the center of the through hole ring (241). The other end of the bimetallic strip (244) is connected to the folding baffle (243). The folding baffle (243) is foldable. Therefore, the folding baffle (243) that was originally folded together will open outward along the slide (242). At this time, the hole between the heating component (25) and the outer shell (21) will shrink.
