Description

Technical Field

[0001] This invention relates to the field of medical product manufacturing equipment, and in particular to an integrated machine for quantitative impregnation and extrusion of alcohol-soaked cotton balls. Background Technology

[0002] Alcohol swabs are consumables widely used in medical, nursing, and daily life fields. In medical disinfection scenarios, alcohol swabs are key materials for skin disinfection and instrument wiping; meanwhile, in the field of traditional Chinese medicine physiotherapy (such as cupping and scraping), alcohol swabs are often used as ignition sources or carriers for dipping specific medicinal solutions to achieve specific therapeutic purposes.

[0003] Traditional alcohol swab production methods, whether for disinfection or cupping, largely rely on manual operation or semi-automated equipment. The main drawbacks are: 1) Low production efficiency: The processes of manual feeding, sorting, soaking, and squeezing lack continuity and automation, making it difficult to meet the demands of large-scale production. 2) Poor quality uniformity: The soaking or coarse spraying methods commonly used in the soaking stage cannot precisely control the amount of liquid (such as alcohol or specific medicinal solutions) absorbed by each swab, resulting in large fluctuations in the effective ingredient content of the finished product, affecting the reliability of disinfection effects or the consistency of therapeutic operations. 3) Uneven liquid distribution: The lack of an effective and controllable homogenization process after soaking leads to uneven liquid distribution within the swab, potentially resulting in localized saturation or insufficient liquid, affecting the effectiveness and safety of use (e.g., heat control during cupping). 4) Lack of online quality control: The production process lacks a rapid online detection and automatic rejection mechanism for the raw materials (such as weight and integrity), allowing substandard products to easily flow into subsequent processes.

[0004] Therefore, a technical solution to the above problems is needed. Summary of the Invention

[0005] In order to solve the technical problems existing in the prior art, the purpose of this invention is to provide an integrated machine for quantitative impregnation and extrusion of alcohol cotton balls to solve the above-mentioned technical problems.

[0006] To achieve its objective, the present invention employs the following technical solution: An integrated machine for quantitative impregnation and squeezing of alcohol swabs, including: Machine tool; A feeding mechanism, installed on the machine platform, is used to transport cotton balls and detect them; A liquid injection mechanism, mounted on the machine platform and connected to the feeding mechanism, is used to receive qualified cotton balls from the feeding mechanism and perform quantitative liquid injection; and A homogenizing mechanism, set on the machine base and connected to the liquid injection mechanism, is used to receive the injected cotton balls and squeeze the cotton balls to make the liquid distribution uniform. The feeding mechanism, the liquid injection mechanism, and the homogenizing mechanism are connected in sequence.

[0007] In some embodiments, the feeding mechanism includes: Vibratory feeder; The first chute, whose input end is connected to the output end of the vibratory feeder, is inclined; and The detection structure, connected to the end of the first slide, is used to detect cotton balls and reject defective products.

[0008] In some embodiments, the detection structure includes: A stop frame, connected to the end of the first slide, is used to hold a single cotton ball; A weighing sensor is fixed to the inner surface of the stop frame and is used to detect the weight of the cotton ball inside the stop frame; An air pump is located at the bottom of the dwell frame; Multiple air vents are formed through the bottom of the dwell frame, and these air vents are connected to the output end of the air pump via a transmission pipe; and A pushing component, disposed in the dwell frame, is used to push a cotton ball that has passed the weighing sensor test to the liquid injection mechanism.

[0009] In some embodiments, the actuating component includes: The swing arm is rotatably connected to the stop frame; A connector, one end of which is hinged to the top of the swing arm; A horizontal plate, hinged to the other end of the connector, and slidably connected to the stop frame; and The push plate is fixedly connected to the horizontal plate and located within the stopping frame; The swing arm can be driven to rotate, and through the connector and the cross plate, it drives the push plate to move within the stop frame to push out the cotton ball.

[0010] In some embodiments, the actuating component further includes: A blocking plate, fixedly connected to the side of the push plate and slidably connected to it through the side wall of the stopping frame, is driven to block the passage between the first slide rail and the stopping frame when the push plate moves; and A sealing plate, connected to the push plate, is used to open or close the opening of the dwell frame facing the injection mechanism as the push plate moves.

[0011] In some embodiments, the injection mechanism includes: The second slide is inclined, and one end of it is used to receive cotton balls from the feeding mechanism; A position sensor, installed on the second slide rail, is used to sense the position of the cotton ball; A liquid injection assembly, disposed above the second slide, includes a liquid cylinder, a drain pipe communicating with the liquid cylinder, a peristaltic pump for driving a metered liquid flow, and an injection nozzle. The drain pipe passes through the peristaltic pump and connects to the injection nozzle. An electrically driven lifting plate is vertically mounted at the end of the second slide rail and is used to control the release of cotton balls. The peristaltic pump can control the injection nozzle to spray liquid onto the cotton ball when the position sensor detects the cotton ball.

[0012] In some embodiments, the homogenizing mechanism includes: Mounting bracket, disposed on the machine base and having an opening communicating with the outlet of the injection mechanism; Two pressure rollers are rotatably mounted in parallel on the mounting frame for receiving and conveying cotton balls from the opening; A compression structure, disposed on the mounting frame and located above the pressure rollers, is used to apply downward pressure to squeeze the cotton ball between the two pressure rollers; A roller, inclined below the pressure roller, is used to receive and guide the rolling of the squeezed cotton ball; and A frame, located below the end of the roller, is used to store cotton balls.

[0013] In some embodiments, the extrusion structure includes: The hydraulic cylinder is fixed on the mounting bracket. A lever, connected to the output shaft of the hydraulic cylinder; and The pressure plate is hinged to the mounting bracket on one side and abuts against the lever on the other side; When the hydraulic cylinder drives the lever to move, it causes the pressure plate to rotate and press down around the hinge point.

[0014] In some embodiments, the mounting position of at least one of the two pressure rollers is adjustable to change the gap between the two pressure rollers.

[0015] In some embodiments, the homogenizing mechanism includes a slider and an adjusting screw, with one end of one of the two pressure rollers mounted on the slider. The slider is slidably connected to the mounting frame, and the adjusting screw is rotatably connected to the mounting frame and screwed to the slider. The adjusting screw can adjust the position of the slider on the mounting frame.

[0016] This invention features a feeding mechanism, a liquid injection mechanism, and a homogenizing mechanism. From feeding, detection, liquid injection to homogenizing and extrusion, the various mechanisms are seamlessly connected to form a closed-loop production line, realizing fully automated continuous production. This greatly improves production efficiency, significantly reduces manual intervention and costs, and is suitable for large-scale production.

[0017] The material handling mechanism of this invention integrates an online detection unit based on a high-precision weighing sensor, which can identify and remove cotton balls that do not meet the weight requirements in real time and automatically, ensuring the basic quality consistency of the product from the source and preventing unqualified products from entering the core liquid injection process.

[0018] This invention's injection mechanism, through precise linkage between position sensing and the injection structure, controls the operation of metering devices such as peristaltic pumps, achieving precise and quantitative liquid spraying for each qualified cotton ball. This method overcomes the inherent defect of uncontrollable dosage in traditional soaking methods, ensuring highly accurate and consistent adsorption of each cotton ball, whether for disinfectant alcohol or therapeutic solutions, greatly improving the standardization of the product's effective ingredient content.

[0019] The homogenization mechanism of this invention employs motor-driven, counter-rotating pressure rollers, combined with an intelligently triggered extrusion structure, to perform flexible and uniform mechanical extrusion on the impregnated cotton balls. This design not only strongly promotes the uniform penetration and distribution of liquid between the fibers inside the cotton ball but also squeezes out excess liquid, achieving an optimal and uniform wetting state for the cotton ball. The equipment allows for convenient adjustment of the pressure roller gap via adjusting the screw, thus flexibly adapting to the extrusion force required for cotton balls of different thicknesses and densities or liquid viscosities, demonstrating strong process adaptability.

[0020] This invention is not limited to the production of traditional alcohol swabs; its liquid injection system is adaptable to various liquids (such as disinfectants of different concentrations, traditional Chinese medicine solutions, etc.), and can be quickly converted for different production uses by changing the liquid source. The fully enclosed assembly line design reduces the risk of contamination during production, and the residual liquid tray under the homogenizing mechanism facilitates the collection and treatment of waste liquid, maintaining a clean and safe production environment that meets modern clean production standards.

[0029] See Figure 1 The diagram shown is a structural schematic of an alcohol cotton ball quantitative impregnation and extrusion integrated machine according to the present invention.

[0030] See Figures 1 to 5 An integrated machine for quantitative impregnation and extrusion of alcohol-soaked cotton balls includes a machine base 1, a feeding mechanism 2, a liquid injection mechanism 3, and a homogenizing mechanism 4. All three mechanisms are mounted on the machine base 1. The feeding mechanism 2 transports and inspects the cotton balls. The liquid injection mechanism 3 connects to the feeding mechanism 2 and feeds the cotton balls to the liquid injection mechanism 3 for liquid injection. The homogenizing mechanism 4 connects to the liquid injection mechanism 3, and the liquid-injected cotton balls are then sent to the homogenizing mechanism 4, where the liquid is homogenized to achieve a more uniform consistency. This invention achieves a fully automated process from feeding, screening, quantitative liquid injection, to extrusion and homogenization of cotton balls through continuous operation of the feeding mechanism 2, the liquid injection mechanism 3, and the homogenizing mechanism 4, significantly improving production efficiency and reducing manual intervention.

[0031] Among them, see Figures 1 to 3The feeding mechanism 2 includes a vibratory feeder 201 for feeding, a first slide 202 connected to the vibratory feeder 201, and a detection structure for detecting cotton balls. The output end of the vibratory feeder 201 is fixedly connected to the first slide 202. The first slide 202 is inclined and the end of the first slide 202 is fixedly connected to the detection structure, so that cotton balls can be fed and the detection structure can detect whether the cotton balls are qualified.

[0032] The detection structure includes a stop frame 203 connected to the end of the first sliding track, a weighing sensor 204 fixed to the inner surface of the stop frame 203, and an air pump 206 fixed to the bottom of the stop frame 203. The weighing sensor 204 has several air holes 205 that penetrate the bottom of the stop frame 203. The output end of the air pump 206 is connected to a transmission pipe 207. The end of the transmission pipe 207 away from the air pump 206 is connected to the air holes 205. The weighing sensor 204 can be used to detect the weight of the cotton ball, and then the air pump 206 delivers air to the air holes 205 to blow out the unqualified cotton ball in the stop frame 203.

[0033] Preferably, the detection structure is further provided with a guide plate 208 for guiding unqualified cotton balls. When an unqualified cotton ball is blown out, it can be guided by the guide plate 208 to be blown to a designated position. Specifically, in this embodiment, the guide plate 208 is fixedly connected to the top of the stopping frame 203. The top of the guide plate 208 is inclined towards the middle of the stopping frame 203. After the cotton ball is blown up, it contacts the guide plate 208 and is guided away from the detection structure.

[0034] The detection structure is also equipped with a pushing structure for pushing the cotton ball out. After the cotton ball is detected as qualified by the weighing sensor 204, it can be pushed to the liquid injection mechanism 3 for liquid injection through the pushing structure. Specifically, in this embodiment, the pushing structure includes a cylinder 209 fixedly mounted on the outer side of the resting frame 203, a swing arm 210 hinged to the output shaft of the cylinder 209, a connector 211 hinged to the top of the swing arm 210, a horizontal plate 212 hinged to the other end of the connector 211, and a push plate 213 fixedly connected to the end of the horizontal plate 212 away from the connector 211. The swing arm 210 is rotatably connected to the resting frame 203, and the connection between the swing arm 210 and the resting frame 203 is near the lower part of the swing arm 210. The horizontal plate 212 is slidably connected to the resting frame 203. The push plate 213 is disposed inside the resting frame 203. The cylinder 209 can drive the swing arm 210 to rotate in the resting frame 203. The swing arm 210 can push the push plate 213 to move inside the resting frame 203 through the horizontal plate 212, thus pushing out the cotton ball.

[0035] The pushing structure also includes a baffle plate 214 fixedly connected to the side of the push plate 213, a frame 215 fixedly connected to the top of the push plate 213, and a sealing plate 217 connected to the bottom of the frame 215. The baffle plate 214 passes through the stop frame 203 and is slidably connected to it. When the push plate 213 is driven to push the cotton ball in the stop frame 203, the baffle plate 214 is driven to block between the first slide 202 and the stop frame 203, preventing the cotton ball in the first slide 202 from entering the stop frame 203 again. The side of the stop frame 203 closest to the injection mechanism 3 is open. When the push plate 213 moves, the frame 215 can also move relative to the stop frame 203, so that the sealing plate 217 can close or open the opening on one side of the stop frame 203, so that the cotton ball can be sent to the injection mechanism 3.

[0036] Preferably, a spring rod 216 is symmetrically installed on one side of the stop frame 203 relative to the cylinder 209, and the sealing plate 217 is also slidably disposed on the spring rod 216. Through the action of the spring rod 216, the sealing plate 217 is always closed on the side of the stop frame 203 near the liquid injection mechanism 3 when no external force is applied. The sealing plate 217 only opens the opening when the push plate 213 is driven, so that the cotton ball can be sent to the liquid injection mechanism 3.

[0037] See Figure 4 The liquid injection mechanism 3 includes a second slide 301, a liquid injection structure set on the second slide 301, and a position sensor 303. The cotton ball is conveyed to the second slide 301 by the feeding mechanism 2. When the cotton ball slides on the second slide 301 and reaches the position of the liquid injection structure, it is sensed by the position sensor 303, which controls the liquid injection structure to inject liquid into the cotton ball, thus automating the liquid injection.

[0038] The second slide 301 is located on the lower side of the stop frame 203. The second slide 301 is inclined. A blocking member 302 is fixedly installed on the top of the second slide 301. The position sensor 303 is fixedly installed on the inner surface of the second slide 301. An electric lifting plate 304 is slidably installed at the end of the second slide 301, which can block or release the cotton ball.

[0039] The liquid injection structure includes a liquid cylinder 305 detachably mounted on the side wall of the second slide 301, a drain pipe 306 connected to the bottom of the liquid cylinder 305, a peristaltic pump 307 fixedly mounted on the second slide 301, and an injection nozzle 308. The injection nozzle 308 is fixedly connected to the second slide 301, and the drain pipe 306 passes through the peristaltic pump 307 and is connected to the injection nozzle 308.

[0040] In this embodiment, after the cotton ball falls from the resting frame 203, it enters the second slide rail 301 and rolls down along the second slide rail 301 to the position sensor 303. At this time, the position sensor 303 is triggered to work, and the position sensor 303 outputs a control signal to the controller (e.g., PLC). The controller drives the peristaltic pump 307 to work once. The end of the peristaltic pump 307 rotates, squeezing the drain pipe 306, so that the drain pipe 306 discharges liquid into the injection nozzle 308. After the injection nozzle 308 injects liquid, it sprays the liquid to be injected onto the cotton ball at the bottom, completing the quantitative spraying. After the injection nozzle 308 has finished working, the electric drive lifting plate 304 is raised upward, and the cotton ball that has completed the injection rolls downward.

[0041] See Figure 5 The homogenizing mechanism 4 includes a mounting frame, a pressure roller 404 mounted on the mounting frame for squeezing cotton balls, a squeezing structure for squeezing cotton balls, a roller frame 410 for conveying the squeezed cotton balls, and a frame 413 for storing cotton balls. After being injected with liquid, the cotton balls are conveyed to the pressure roller 404 on the mounting frame. Through the squeezing of the pressure roller 404 and the squeezing structure, the liquid on the cotton balls is more evenly distributed. Then the cotton balls fall onto the roller frame 410 and roll down into the frame 413 for storage.

[0042] The mounting frame includes a first mounting frame 401 fixedly mounted on the machine base 1 and a second mounting frame 403 disposed opposite to the first mounting frame 401. A through-hole 402 is provided through the first mounting frame 401, connecting and communicating with the bottom of the second slide rail 301, allowing cotton balls to be conveyed onto the mounting frame. Two pressure rollers 404 are provided, rotatably mounted on the side of the first mounting frame 401 and the second mounting frame 403 close to each other, receiving and squeezing the cotton balls.

[0043] The extrusion structure includes a hydraulic cylinder 405 located above the two pressure rollers 404 on the first mounting frame 401, a lever 406 fixedly connected to the output shaft of the hydraulic cylinder 405, and a pressure plate 407 hinged to the first mounting frame 401 on the side of the lever 406. One side of the pressure plate 407 abuts against the lever 406. When the hydraulic cylinder 405 is working, it drives the lever 406 to move, so that the pressure plate 407 presses on the cotton ball on the pressure rollers 404, so that the cotton ball is squeezed between the two pressure rollers 404.

[0044] Preferably, the extrusion structure is also provided with a distance sensor (not shown) for sensing the position of the cotton ball.

[0045] Preferably, the two pressure rollers 404 can also move relative to each other to adjust the gap between them and control the squeezing force on the cotton ball. Specifically, in this embodiment, one of the pressure rollers 404 has sliders 408 sleeved at both ends. The sliders 408 are slidably connected to the first mounting frame 401 and the second mounting frame 403, respectively. An adjusting screw 409 is screwed to the center of the slider 408. The adjusting screw 409 is rotatably connected to the second mounting frame 403, respectively. By adjusting the adjusting screw 409, the slider 408 moves on the first mounting frame 401 and the second mounting frame 403, thereby adjusting the distance between the two pressure rollers 404.

[0046] The roller frame 410 includes two arc-shaped rods disposed between the first mounting frame 401 and the second mounting frame 403. The roller frame 410 is located at the bottom of the pressure roller 404 and is inclined toward the second mounting frame 403. The roller frame 410 is adapted to the size of the cotton ball. The frame 413 is disposed at the end of the roller frame 410. The cotton ball falls on the roller frame 410 and can be rolled into the frame 413 for storage.

[0047] Preferably, the bottom of the roller frame 410 is provided with a residual liquid tray 411, and the bottom opening 412 is provided through the second mounting bracket 403 near the bottom end of the roller frame 410. The roller frame 410 is inclined towards the bottom opening 412, and the frame 413 is provided outside the bottom opening 412 of the second mounting bracket 403.

[0048] It also includes a drive device 414 for driving the pressure rollers 404 to rotate, so that the cotton balls falling between the pressure rollers 404 can be squeezed. Preferably, the drive device 414 can be a drive motor mounted on the second mounting bracket 403 and the slider 408, with gears or belts on the pressure rollers 404 connected to the drive motor for transmission. The drive motor is used to drive the pressure rollers 404 to rotate and squeeze the cotton balls. Alternatively, in some other embodiments, the drive motor can be mounted only on the second mounting bracket 403, and the drive motor drives only one of the pressure rollers 404 to rotate. When the cotton balls are squeezed between the two pressure rollers 404, the rotating pressure roller 404 can drive the other pressure roller 404 to rotate.

[0049] In this embodiment, the cotton ball rolls from the injection mechanism 3 through the port 402 between the two pressure rollers 404. Under the action of gravity, it moves towards the distance sensor. Subsequently, the distance sensor is triggered, causing the hydraulic cylinder 405 to start. The output shaft of the hydraulic cylinder 405 drives the lever 406 to extend outward, pressing the pressure plate 407 downward, so that the cotton ball located below is pressed and fully contacts the pressure rollers 404. It is squeezed by the opposing rotating pressure rollers 404. When the pressure rollers 404 rotate, the cotton ball passes between the pressure rollers 404. Through squeezing, the alcohol in the cotton ball is evenly distributed. After the squeezed cotton ball passes through the pressure rollers 404, it falls onto the roller frame 410 and rolls to the other end along the inclined roller frame 410. Excess squeezed alcohol components fall onto the residual liquid tray 411 for collection. The squeezed cotton ball falls into the frame 413 through the bottom port 412.

[0050] In this embodiment, during actual use, depending on the size of the cotton ball and the amount of alcohol to be squeezed out, the operator twists the adjusting screw 409 to make the slider 408 move one of the pressure rollers 404 closer to or further away from the other pressure roller 404.

[0051] It also includes a method for quantitatively impregnating and squeezing alcohol cotton balls using the aforementioned integrated alcohol cotton ball quantitative impregnation and squeezing machine: S1. Cotton ball feeding inspection: A batch of cotton balls enters the first slide 202 via the vibratory feeder 201. A single cotton ball falls to the stop frame 203 for weighing. If it is not qualified, it is blown away by the air pump 206. If it is qualified, the cylinder 209 is triggered to drive the push plate 213 to push the cotton ball to the liquid injection mechanism 3. The baffle plate 214 simultaneously stops the subsequent cotton balls. S2, Cotton ball injection: The cotton ball falls into the second slide 301 and triggers the position sensor 303. The PLC drives the peristaltic pump 307 to work. The liquid is sprayed onto the cotton ball through the nozzle in a metered manner. After the cotton ball is injected, the electric drive lifting plate 304 is raised and the cotton ball continues to slide down. S3, Cotton ball homogenization: The cotton ball output from the liquid injection mechanism 3 rolls into the pressure roller 404 to trigger the distance sensor. The hydraulic cylinder 405 pushes the pressure plate 407 to press down the cotton ball, so that it is squeezed by the pressure roller 404 rotating in opposite directions, and the liquid is evenly distributed.

[0052] It is understood that the liquid sprayed onto the cotton ball can be alcohol, which can then be used for disinfection or cupping. Alternatively, in some other embodiments, the liquid sprayed onto the cotton ball can be a specific medicinal solution, which is not limited here.

[0053] The above are merely some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and all such modifications and improvements fall within the scope of protection of the present invention.
