Description

Technical Field

[0001] This utility model relates to the technical field of hydrogel eye patch processing equipment, specifically a punching device for processing hydrogel eye patches. Background Technology

[0002] In the production and processing of hydrogel eye patches, the die-cutting process is a crucial step in cutting the molded hydrogel material into specific shapes for the eye patches. Currently, most die-cutting devices commonly used in the market for hydrogel eye patch processing employ traditional mechanical die-cutting methods, using die-cutting molds fixed on a stamping press to stamp and cut the hydrogel material.

[0003] Chinese Patent Announcement No. CN214323607U discloses a punching device for processing hydrogel eye patches, relating to the field of medical auxiliary material processing equipment technology. The device includes a worktable, a punching roller, and a feed roller for waste material. The punching roller is rotatably arranged above the worktable, and its circumferential surface is arranged with multiple sets of closed-loop cutting blades. Within the closed-loop area enclosed by the cutting blades, a discharge pusher capable of radial movement is arranged. The feed roller for waste material includes two sets of opposing rollers, and the circumferential linear velocity of the rollers is consistent with that of the punching roller. The feed roller for waste material is located at the downstream end of the punching roller. This punching device for processing hydrogel eye patches adopts a punching roller design, changing the cutting method, reducing reliance on manual labor, and improving production efficiency.

[0004] In the existing technology, when using a punching device for processing hydrogel eye patches, it is necessary to use a variety of tools to perform cumbersome disassembly operations when it is necessary to change the cutting die of different specifications. It may even involve disassembling the entire punching roller structure, which takes a long time. This makes the equipment less flexible in dealing with diverse product needs and unable to quickly switch to producing hydrogel eye patches of different shapes and sizes, resulting in a significant increase in production preparation time. Therefore, we have made improvements to this and proposed a punching device for processing hydrogel eye patches. Utility Model Content

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3 A punching device for processing hydrogel eye patches includes a base 1. Side plates 2 are fixedly installed on both sides of the top of the base 1. A conveying structure 3 and rollers 4 are arranged between the two side plates 2. Fixed seats 7 are slidably connected inside the two side plates 2. Slider blocks 8 are fixedly installed on corresponding sides of the two fixed seats 7 and are slidably connected to the side plates 2. U-shaped mounting blocks 9 are slidably connected inside the two fixed seats 7. Two insert rods 10 are fixedly installed on the side of the two U-shaped mounting blocks 9 that are close to each other. The insert rods 10 pass through one side of the fixed seat 7 and are slidably connected to it. Multiple insert rods 10 are inserted into the inside of the rollers 4 and are slidably connected to them. Two electric telescopic rods 11 are fixedly installed inside the two fixed seats 7 and on corresponding sides of the rollers 4. The output ends of the multiple electric telescopic rods 11 are fixedly connected to the U-shaped mounting blocks 9. Multiple hydrogel eye patch molds 5 are fixedly installed on the outside of the rollers 4. Cutting blades 6 are fixedly installed on the side of the multiple hydrogel eye patch molds 5 away from the rollers 4.

[0035] In this embodiment of the utility model, the quick replacement function of the roller 4 is based on the synergistic effect of the insert rod 10 and the electric telescopic rod 11. When it is necessary to change the mold, the control system sends a retraction command to the electric telescopic rod 11. The output end of the electric telescopic rod 11 drives the back-shaped mounting block 9 to move away from the roller 4. Since the insert rod 10 is fixedly connected to the back-shaped mounting block 9, the insert rod 10 is simultaneously withdrawn from the insertion hole of the roller 4, releasing the axial constraint on the roller 4. At this time, the roller 4 is only slidably connected to the fixed seat 7 through the slider 8, and can be easily pulled out along the guide rail to achieve quick disassembly.

[0036] Example 2: Please refer to the appendix of the instruction manual. Figure 1-6 In a preferred embodiment of this utility model, a first servo motor 12 is fixedly installed inside each of the two side plates 2. A threaded rod 13 is fixedly installed at the output end of each of the two first servo motors 12, and the threaded rod 13 is rotatably connected to the side plate 2. The two threaded rods 13 pass through one of the sliders 8 on one side of the two fixed seats 7 and are threadedly connected to them. A guide rod is fixedly installed inside each of the two side plates 2, and the two guide rods pass through the other slider 8 on one side of the two fixed seats 7 and are slidably connected to them.

[0037] External gear rings 14 are fixedly installed on the corresponding sides of roller 4. Gears 15 are meshed on the outer sides of the two external gear rings 14. Worm gears 17 are rotatably connected inside the two side plates 2. A fixing rod is fixedly installed between two adjacent gears 15 and worm gears 17, and the fixing rod is inserted into the side plate 2 and rotatably connected to it. Worms 18 are meshed on the outer sides of the two worm gears 17. The two worms 18 are rotatably connected to the two side plates 2 respectively.

[0038] A second servo motor 19 is fixedly installed inside one of the side plates 2. A synchronous belt structure 20 is provided above the base 1. The synchronous belt structure 20 consists of a first synchronous belt and two first synchronous pulleys, and the first synchronous belt and the two first synchronous pulleys are connected in a transmission connection. The output end of the second servo motor 19 is fixedly connected to one of the first synchronous pulleys, and the two first synchronous pulleys are fixedly connected to two worm gears 18 respectively.

[0039] A base plate 21 is fixedly installed between the two side plates 2. The roller 4 consists of a conveyor belt, a second synchronous belt, a third servo motor, two second synchronous wheels and a transmission roller. The base plate 21 is slidably connected to the conveyor belt.

[0040] The roller 4 has multiple pumps 23 inside, and multiple connecting cavities 22 that cooperate with the pumps 23 are opened on the roller 4. The output ports of the multiple pumps 23 are all connected to the connecting cavities 22. Multiple second cavities 26 are opened inside the roller 4 and outside the multiple connecting cavities 22, and the second cavities 26 are connected to the connecting cavities 22. Multiple first cavities 24 that cooperate with the second cavities 26 are opened on the roller 4.

[0041] Pistons 25 are slidably connected inside the multiple second cavities 26, and the pistons 25 are inserted into and slidably connected to the first cavity 24. Infrared sensors are fixedly installed inside the rollers 4 and located inside the multiple second cavities 26.

[0042] Static eliminators 16 are embedded on the side of the two side plates 2 that are close to each other, and a controller 27 is embedded on one side of the base 1. The controller 27 is electrically connected to the first servo motor 12, the static eliminator 16, the second servo motor 19, the pump 23 and the infrared sensor.

[0043] In this embodiment of the utility model, the fixed seat 7 and the side plate 2 are slidably connected by the cooperation of the slider 8 and the guide rod. The guide rod provides guidance for the movement of the fixed seat 7, ensuring the stability and accuracy of the fixed seat 7 when it moves horizontally under the drive of the first servo motor 12, thereby accurately adjusting the position of the roller 4 and the hydrogel eye patch mold 5.

[0044] The rotation of roller 4 is achieved through the precision transmission of gear 15, worm gear 17 and worm 18. The external gear ring 14 is fixed on both sides of roller 4 and meshes with gear 15. Gear 15 is connected to worm gear 17 through a fixed rod. Worm gear 17 meshes with worm 18. Through the multi-stage transmission structure, the roller 4 can rotate precisely, accurately moving the hydrogel eye patch mold 5 and cutter 6 to the punching position. Through the above structure and transmission principle, the device can precisely control the position and movement trajectory of the punching mold, so that the hydrogel material can be processed into a specific shape according to the design requirements during the punching process. This effectively avoids problems such as inaccurate eye patch size and irregular shape caused by position deviation, significantly improves the punching accuracy and quality of eye patches, and meets the market demand for high-quality hydrogel eye patches.

[0045] The pump 23, connecting chamber 22, second chamber 26, first chamber 24, piston 25, and infrared sensor inside the roller 4 together constitute a material adsorption and fixation system. When the pump 23 is working, it delivers gas through the connecting chamber 22 to the second chamber 26, pushing the piston 25 to slide in the second chamber 26, causing the first chamber 24 to generate suction, thereby tightly adsorbing and fixing the hydrogel material onto the roller 4. The infrared sensor detects the position of the piston 25 in the second chamber 26 in real time. When the position of the piston 25 changes, it means that the suction of the first chamber 24 has changed. The infrared sensor feeds back the detected information to the controller 27. The controller 27 adjusts the working intensity of the pump 23 according to the preset suction standard to ensure stable suction and ensure that the hydrogel material does not move during the punching process.

[0046] Static eliminators 16 are embedded on the side of the two side plates 2 that are close to each other. During the operation of the device, static electricity is easily generated due to friction between the components and material conveying. Static eliminators 16 release ions with opposite charges to neutralize the static electricity generated on the surface of the equipment and materials, thereby eliminating static electricity. Controller 27 is electrically connected to static eliminators 16 and can control the working intensity and opening and closing of static eliminators 16 according to the operating status of the equipment to ensure that static electricity is effectively eliminated.

[0047] The device is controlled by controller 27, and a heat dissipation hole is provided on the device to cooperate with the motor.

[0048] Example 3: Please refer to the appendix of the instruction manual. Figure 1 , Figure 2 and Figure 4 In a preferred embodiment of this utility model, a U-shaped baffle is provided between the two side plates 2, and the U-shaped baffle is inserted into the two side plates 2 and slidably connected thereto. A collection box is fixedly installed on the top of the U-shaped baffle, and an air suction pump is provided on the top of the collection box, penetrating through the top of the collection box and fixedly connected thereto. Weight blocks are fixedly installed on both sides of the inside of the collection box. Multiple air inlet chambers are opened inside the U-shaped baffle, and multiple air inlet holes are opened on the inner walls of the adjacent sides of the U-shaped baffle, communicating with the air inlet chambers. A weight block is fixedly installed on the bottom of the inner wall of the collection box. Multiple inclined pipes that cooperate with the air intake chamber; the bottom of the inner wall of the collection box is inclined; a filter plate, an activated carbon plate, and a honeycomb catalyst plate are slidably connected inside the collection box; a door is provided on one side of the collection box, and the door is inserted into the collection box and slidably connected thereto; the door is slidably connected to the filter plate, activated carbon plate, and honeycomb catalyst plate; multiple fixing bolts are provided on the side of the door away from the collection box, and all the fixing bolts pass through the door and are threaded to it; all the fixing bolts are inserted into the collection box and are threaded to it; the controller 27 is electrically connected to the air intake pump.

[0049] In this embodiment of the utility model, the exhaust gas treatment system mainly consists of a U-shaped baffle, a collection box, an air pump, and related pipes and filter components. During the punching process, the air pump generates suction after starting. This suction is transmitted to the punching area through the air inlet and air inlet chamber inside the U-shaped baffle. The U-shaped baffle is set between the two side plates 2, and its position is close to the punching station, which can effectively collect the exhaust gas generated during the punching process.

[0050] The weight blocks fixedly installed on both sides of the box can ensure that the collection box remains stable when the air pump is working, and avoid the shaking caused by negative pressure that affects the purification effect. The bottom of the inner wall of the collection box is designed to be inclined, which, together with the inclined pipe, can guide the impurities in the exhaust gas to flow obliquely to the side of the box door.

[0051] After entering the collection box, the exhaust gas undergoes purification treatment sequentially through a filter plate, an activated carbon plate, and a honeycomb catalyst plate. The filter plate uses high-precision filter mesh material, which can intercept larger impurities such as dust and particulate matter carried in the exhaust gas, preventing these substances from clogging subsequent purification components. The activated carbon plate utilizes its rich porous structure and strong adsorption capacity to adsorb odor molecules and volatile organic compounds in the exhaust gas, effectively removing irritating odors. The honeycomb catalyst plate, through its surface-loaded catalyst, catalytically decomposes organic pollutants in the exhaust gas under suitable conditions, converting them into harmless substances such as carbon dioxide and water, achieving deep purification of the exhaust gas.

[0052] The door and the collection box are slidably connected and secured with bolts, which facilitates the regular replacement and maintenance of the filter plates, activated carbon plates and honeycomb catalyst plates. After the purified exhaust gas passes through all the filter components, it can meet the environmental emission standards and be discharged through the top of the collection box or subjected to further treatment.

[0053] In this embodiment of the invention, the exhaust gas purification system can effectively remove various exhaust gas pollutants generated during the punching process through multiple filtration and purification processes. If the exhaust gas is not effectively treated during the production of hydrogel eye patches, residual odors and pollutants may adhere to the product surface, affecting the quality and user experience of the eye patches. This purification system can completely eliminate the potential pollution of the product by the exhaust gas, ensuring the safety and purity of the eye patch products.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
