Description

Technical Field

[0001] This invention belongs to the field of sterilization equipment technology, specifically relating to an ultraviolet sterilization device for the production of medical wipes. Background Technology

[0002] Medical wipes are a convenient and effective hygiene tool, specifically designed for medical environments for cleaning and disinfection. They differ significantly from ordinary wet wipes used daily in function, standards, and applicable scenarios, and are widely used in hospitals, homes, and public places to help prevent infection and maintain health. During the production process of medical wipes, the semi-finished roll material after soaking in liquid requires ultraviolet sterilization. After sterilization, it is then cut into equal-sized finished medical wipes. However, the following problems exist when sterilizing the semi-finished roll material: After prolonged use, water vapor and pesticide residues from wet wipes will adhere to the surface of the UV lamp tubes, forming a blocking layer that significantly reduces the UV transmission intensity and causes the sterilization effect to continuously decline. Manually stopping the machine to wipe and clean it will interrupt the production line and reduce processing efficiency. Furthermore, the sterilization effect of UV germicidal lamps is related to the intensity of the light and the irradiation time. Existing equipment does not have the function of adjusting the UV irradiation intensity according to the conveying speed of the semi-finished roll material after soaking, requiring manual stopping for adjustment, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and rationally designed ultraviolet sterilization device for the production of medical wet wipes in order to solve the above-mentioned problems.

[0014] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, this invention uses the cabinet door and reciprocating scraping components in combination to simultaneously scrape and clean the surface of the ultraviolet germicidal lamp while the cabinet door is opening and closing. This automatically removes water vapor and chemical residue adhering to the surface of the ultraviolet germicidal lamp, eliminating the need for manual wiping and significantly improving the efficiency of wet wipe sterilization production. At the same time, when the cabinet door is opened, releasing the contact switch automatically stops the ultraviolet germicidal lamp and the unwinding mechanism, achieving foolproof equipment and avoiding damage from ultraviolet radiation caused by accidental opening of the cabinet door.

[0015] 2. Unlike existing technologies, when the reciprocating scraping component and the collecting and pouring component move to the last side, the top rod automatically opens the sealing cover, automatically discharges the wastewater collected inside the collection frame, and collects it automatically through the collection mechanism. There is no need for manual periodic cleaning of the collection frame. The waste collection box itself is detachable, and it can be directly pulled out and poured out when the waste liquid is full. The disassembly, assembly and cleaning operations are simple.

[0016] 3. Unlike existing technologies, this invention utilizes two ultraviolet germicidal lamps arranged symmetrically, simultaneously irradiating both sides of the medical wipes, ensuring thorough disinfection without blind spots and achieving a superior sterilization effect compared to single-sided irradiation devices.

[0017] 4. Unlike existing technologies, this invention uses a linear velocity sensor to collect the rolling material feed speed in real time. The speed data is transmitted to the controller.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Please refer to Figure 1 , Figure 2 and Figure 4An ultraviolet sterilization device for the production of medical wipes includes a sterilization cabinet 1, which is a completely sealed sterilization chamber providing a sealed environment and a mounting base for its internal components. A maintenance door (not shown in the figure) is provided on the rear side of the sterilization cabinet 1, and the maintenance door is sealed to the sterilization cabinet 1. Two cabinet doors 2 are hinged to the front side of the sterilization cabinet 1. An unwinding mechanism 4 for unwinding semi-finished medical wipes is provided inside the sterilization cabinet 1. A vertical partition 6 is fixedly installed on the rear side of the interior of the sterilization cabinet 1, and a sterilization mechanism 5 is provided on the vertical partition 6 for irradiating and sterilizing the semi-finished medical wipe rolls. A flow channel 11 is opened inside the vertical partition 6 for guiding water vapor. A collection mechanism 9 is provided on the rear side of the vertical partition 6 for collecting the guided water vapor. A horizontal partition 7 is fixedly installed on the top of the interior of the sterilization cabinet 1, and a controller 8 is fixedly installed on one side of the top of the horizontal partition 7.

[0022] Please see Figure 3 , Figure 4 and Figure 5 The unwinding mechanism 4 includes a support 42 fixedly installed on the rear side of the vertical partition 6. A servo motor 41 is fixedly installed inside the support 42. The servo motor 41 provides a precise power source for the unwinding and rewinding of the wet wipes. A linear speed sensor (not shown in the figure) is set at the top inside the sterilization cabinet 1. The linear speed sensor collects the actual unwinding linear speed of the wet wipes in real time and transmits the speed data to the controller 8. The controller 8 automatically adjusts the output power of the sterilization lamp according to the speed signal, so that the faster the speed, the greater the intensity of ultraviolet irradiation, and the constant total sterilization dose. It does not require manual shutdown for adjustment, which is highly efficient and avoids the problems of inadequate sterilization and over-sterilization. The output end of the servo motor 41 rotates through the rear side of the vertical partition 6 and is fixedly installed with a take-up roller 43. Several transmission rollers 44 are rotatably set on the front side of the vertical partition 6. Medical wet wipes are wound on the several transmission rollers 44. A take-up reel 47 is fixedly sleeved on the take-up roller 43. An unwinding roller 46 is rotatably installed at the bottom of the vertical partition 6. An unwinding reel 45 is sleeved on the outside of the unwinding roller 46.

[0023] When in use, open cabinet door 2, place the semi-finished roll material to be sterilized onto unwinding reel 45, then wind the roll material around multiple drive rollers 44 and fix the wet wipe material onto take-up reel 47. At this time, start servo motor 41, and the output of servo motor 41 synchronously drives take-up reel 47 to rotate. Take-up reel 47 is used to wind up the wipes. At the same time, the pull of the wet wipes drives unwinding roller 46 and unwinding reel 45 to rotate. Unwinding reel 45 unwinds synchronously. During the unwinding process, sterilization mechanism 5 sterilizes the wipes synchronously from top to bottom.

[0024] Please see Figure 3 , Figure 6 and Figure 7The sterilization mechanism 5 includes several fixed seats 51 mounted on a vertical partition 6. The fixed seats 51 are fixedly mounted on the vertical partition 6 by bolts 56. The fixed seats 51 are divided into two groups and are symmetrically distributed vertically. Mounting seats 54 are fixedly mounted on the fixed seats 51. A first ultraviolet germicidal lamp 52 is mounted on the upper mounting seat 54, and a second ultraviolet germicidal lamp 53 is mounted on the lower mounting seat 54. A collection and tilting assembly 57 is provided on both the first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53. A reciprocating scraping assembly 55 is provided on the collection and tilting assembly 57.

[0025] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53 respectively irradiate and sterilize the top and bottom of the medical wipes. The collection and pouring assembly 57 includes multiple ear blocks 576 symmetrically fixed on the mounting base 54. The ear blocks 576 are arranged in pairs and symmetrically distributed. A guide rod 575 is fixedly installed between the two ear blocks 576 in the same group. A guide plate 577 is slidably sleeved on the guide rod 575. A scraper ring 574 is fixedly installed between the two guide plates 577. The scraper ring 574 is slidably sleeved on the outside of the first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53. U-shaped mounting arms 578 are fixedly installed on both sides of the outside of the scraper ring 574. A collection frame 571 is fixedly installed at the bottom of the two U-shaped mounting arms 578. A guide groove 572 is opened on the bottom surface of the inside of the collection frame 571. An automatic opening and closing assembly 573 is set in the middle of the rear side of the collection frame 571. The position of the automatic opening and closing assembly 573 corresponds to the position of the flow channel groove 11.

[0026] Please see Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The automatic opening and closing assembly 573 includes a discharge pipe 5731 fixedly connected to the rear side of the collection frame 571. A second hinge seat 5734 is fixedly installed on the top of the discharge pipe 5731. A connecting arm 5732 is rotatably installed on the second hinge seat 5734. A coil spring (not shown in the figure) is provided between the second hinge seat 5734 and the connecting arm 5732. A sealing cover 5733 is fixedly installed on one side of the bottom of the connecting arm 5732. The sealing cover 5733 is sealed to the discharge pipe 5731. The coil spring is used to keep the sealing cover 5733 pressed against the discharge pipe 5731 at all times. A fixing block 5735 is fixedly installed on the top of the connecting arm 5732. A top rod 12 corresponding to the position of the fixing block 5735 is fixedly installed inside the top of the flow channel 11.

[0027] Please see Figure 4 and Figure 8The reciprocating scraping assembly 55 includes a linkage rod 554 fixedly installed on the scraper ring 574. A fixed arm 553 is fixedly installed on the front side of the linkage rod 554. A first connecting rod 552 is hinged to the front side of the fixed arm 553. A first hinge seat 551 is hinged to the front side of the first connecting rod 552. The front side of the first hinge seat 551 is fixedly connected to the rear side of the cabinet door 2. A contact switch 10 is fixedly installed on the front side of the vertical partition 6. The position of the contact switch 10 corresponds to the position of the linkage rod 554. The contact switch 10 is electrically connected to the controller 8. A control panel 3 is hinged to the top of the front side of the sterilization cabinet 1. The controller 8 and the control panel 3 are electrically connected.

[0028] In use, the top and bottom of the semi-finished medical wipe roll are simultaneously irradiated and sterilized using UV germicidal lamps 52 (No. 1) and 53 (No. 2). When the cabinet door 2 of the sterilization cabinet 1 is opened, the hinge seat 551 and its connecting rod 552 move forward simultaneously, as do the fixed arm 553 and its linkage rod 554. This, in turn, causes the scraper ring 574 to move from back to front. When the scraper ring 574 moves forward, it scrapes off the water vapor and pesticide residue from the first UV germicidal lamp 52 and the second UV germicidal lamp 53, which fall into the collection frame 571 for collection. This achieves automatic cleaning and stain collection of the first UV germicidal lamp 52 and the second UV germicidal lamp 53. When the door is closed, the discharge pipe 5731 is inserted into the flow channel groove 11. During the insertion process, the push rod 12 pushes the fixing block 5735, which in turn drives the connecting arm 5732 and the sealing cover 5733 on it to rotate. The hinge shaft of the second hinge seat 5734 rotates, thereby automatically opening the sealing cover 5733. At this time, water and dirt inside the collection frame 571 flow from the discharge pipe 5731 into the flow channel groove 11, thus achieving automatic cleaning of the first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53 and automatic emptying of the collection frame 571 during the opening and closing of the cabinet door 2. When the linkage rod 554 is pressed into contact with the contact switch 10, the first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53 are activated. 53 and servo motor 41 are linked together. When cabinet door 2 is opened, after linkage rod 554 disengages from contact switch 10, the first ultraviolet germicidal lamp 52, the second ultraviolet germicidal lamp 53 and servo motor 41 are automatically powered off to avoid the problem of being exposed to ultraviolet radiation after cabinet door 2 is opened. After top rod 12 disengages from fixing block 5735, under the action of coil spring, sealing cover 5733 presses against discharge pipe 5731, realizing self-sealing between discharge pipe 5731 and sealing cover 5733.

[0029] Please see Figure 4 , Figure 7 and Figure 12The collection mechanism 9 includes a guide rail 94 fixedly installed at the bottom rear side of the vertical partition 6. A guide slider 95 is slidably connected to the guide rail 94. A locking screw 96 is threaded through one side of the top of the guide slider 95. The bottom of the locking screw 96 is in contact with the top of the guide rail 94. A waste collection box 97 is fixedly installed on the guide slider 95. Several connecting pipes 92 are fixedly installed at the rear side of the vertical partition 6. The connecting pipes 92 are fixedly connected to the bottom of the flow channel 11. The ends of the several connecting pipes 92 away from the flow channel 11 are fixedly connected to a manifold 91. Several drain pipes 93 are fixedly connected to the bottom of the manifold 91. The bottom of the drain pipes 93 is located above the waste collection box 97.

[0030] The water flowing into the flow channel 11 enters the manifold 91 through the connecting pipe 92, and then enters the waste collection box 97 through the drain pipe 93 for collection. When the waste collection box 97 is full, loosen the locking screw 96, pull out the waste collection box 97, pour out the clean water in the waste collection box 97, and then insert the guide slider 95 on the empty waste collection box 97 into the guide slide rail 94. After installation, tighten the locking screw 96 to fix it.

[0031] It should be noted that this ultraviolet sterilization equipment for the production of medical wipes, when in use, When loading the equipment, open the cabinet doors 2 on both sides of the sterilization cabinet 1, install the semi-finished roll medical wipes on the unwinding reel 45 behind the vertical partition 6, pull out the end of the wipe and pass it through multiple drive rollers 44 in sequence, and finally roll it up and fix it on the surface of the take-up reel 47, and close the cabinet door 2; Parameter settings: The operator operates the control panel 3 and enters the target sterilization dose and unwinding speed range in the controller 8, and the equipment starts the automatic linkage program.

[0032] Simultaneous unwinding and sterilization: Controller 8 starts servo motor 41, which drives take-up reel 47 to wind up at a uniform speed. The unwind reel 45 automatically unwinds the wet wipes through the pull of the wet wipes, and the wet wipes are horizontally conveyed along the transmission roller 44. A linear speed sensor collects the speed of the wet wipes in real time. The linear speed sensor is a non-contact laser Doppler velocimeter. Controller 8 adjusts the output power of UV germicidal lamp 52 and UV germicidal lamp 53 synchronously according to the speed. The faster the speed, the higher the UV irradiation intensity, maintaining a constant total sterilization dose per unit area. UV germicidal lamp 52 and UV germicidal lamp 53 irradiate the upper and lower surfaces of the wet wipes respectively, completing irradiation sterilization on both sides simultaneously.

[0033] Cabinet door 2 automatically scrapes the lamp tubes. The opening and closing action of cabinet door 2 causes the first hinge seat 551 to move, which pushes the linkage rod 554 to slide horizontally back and forth through the first connecting rod 552 and the fixed arm 553. The linkage rod 554 simultaneously drives the scraping ring 574 to scrape the outer wall of the first ultraviolet germicidal lamp 52 and the second ultraviolet germicidal lamp 53 back and forth to remove the medicine liquid and water mist stains attached to the tube wall. When the scraping ring 574 slides, it simultaneously drives the collection frame 571 to move back and forth to collect the waste liquid and impurities generated by wiping.

[0034] Automatic waste discharge and diversion: When the scraper ring 574 moves the collection frame 571 to the position of the flow channel 11, the fixing block 5735 on the rear side of the collection frame 571 presses against the push rod 12 in the flow channel 11. The push rod 12 pushes the connecting arm 5732 to flip, and the sealing cover 5733 is automatically lifted. The waste liquid in the collection frame 571 is discharged into the flow channel 11 along the discharge pipe 5731. The waste flows down the flow channel 11 through the connecting pipe 92 into the manifold 91, and then falls into the bottom waste collection box 97 through the drain pipe 93.

[0035] When cabinet door 2 is opened, the linkage rod 554 disengages from the contact switch 10, and the first ultraviolet germicidal lamp 52, the second ultraviolet germicidal lamp 53, and the servo motor 41 are automatically powered off to avoid the problem of being exposed to ultraviolet radiation after the cabinet door 2 is opened. At this time, under the action of the coil spring, the sealing cover 5733 and the discharge pipe 5731 self-seal to prevent the leakage of dirt.

[0036] Waste cleaning: After the equipment has been running for a period of time, loosen the locking screw 96, pull out the guide slider 95 and the waste collection box 97 along the guide slide rail 94, pour out the waste liquid and impurities in the box, push it back to its original position after cleaning, and tighten the locking screw 96 to fix it.

[0037] At the end of production, after all the wet wipe rolls have been unrolled and sterilized, the servo motor 41 and the ultraviolet lamp are turned off via the control panel 3, and the cabinet door 2 is opened to take out the sterilized semi-finished product that has been rolled up. The single sterilization operation is completed.

[0038] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
