Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to a disposable medical mask production equipment. Background Technology

[0002] With the development of the manufacturing industry, automation and industrialized production have become the mainstream trend. The emergence of disposable medical mask production equipment is in line with this trend. It can achieve high-speed and efficient automated production. Advanced production equipment can produce thousands or even tens of thousands of masks per hour, which greatly improves production efficiency.

[0003] However, existing disposable medical mask production equipment is not convenient for discharging gauze during use. Due to inertia, the gauze may rotate or reverse during discharge, resulting in wrinkles on the gauze. Therefore, waste occurs during cutting, which leads to resource waste. Utility Model Content

[0004] The purpose of this invention is to provide a disposable medical mask production equipment. By setting an anti-reverse mechanism, it solves the problem of inconvenient gauze discharge. When the gauze is discharged, inertia will cause the gauze to rotate or reverse, resulting in wrinkles on the gauze. Therefore, waste will occur during cutting, which will cause resource waste.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a disposable medical mask production equipment, including a fixing box, on which an anti-reverse mechanism and a cutting mechanism are provided;

[0007] The inner wall of the fixing box is rotatably connected to several rotating shafts, the front sides of which extend rotatably out of the fixing box. A circular roller is fixedly connected to the outer wall of each of the rotating shafts, and a ratchet is fixedly connected to the extension of each of the rotating shafts. The front side of the fixing box is fixedly connected to several rotating shafts, and a limit rod is rotatably connected to the outer wall of each of the rotating shafts. The front side of the fixing box is fixedly connected to several fixing blocks, and a sliding groove is provided on the right side of each of the limit rods.

[0008] Furthermore, each of the several grooves is slidably connected with a slide rod, each of the slide rods is fixedly connected with a slider on its outer wall, and each of the sliders is fixedly connected with a fixing plate on its top.

[0009] Furthermore, spring 1 is fixedly connected to the top of each of the fixed plates, and the top of each of the spring 1 is fixedly connected to the fixed block. Two rotating shafts 3 are fixedly connected to the inner wall of the fixed box, and the front sides of the two rotating shafts 3 extend rotatably out of the fixed box.

[0010] Furthermore, two circular rollers are fixedly connected to the outer walls of the two rotating shafts three, and gears are fixedly connected to the extensions of the two rotating shafts three. The two gears mesh with each other. A motor is fixedly connected to the front side of the fixed box, and the output shaft of the motor is fixedly connected to the rotating shaft three located on the upper side through a coupling.

[0011] Furthermore, the cutting mechanism includes a rotating shaft four that rotatably passes through the front side of the fixed box. Pulleys are fixedly connected to the front extension of the rotating shaft four and the extension of the rotating shaft three located on the lower side. Belts are fixedly connected to the outer walls of the two pulleys, and a turntable is fixedly connected to the rear extension of the belts.

[0012] Furthermore, the turntable is provided with an elliptical groove, and a circular slider is slidably connected in the elliptical groove. A fixed rod is fixedly connected to the rear side of each of the two circular sliders, and a hollow rod is fixedly connected to the side of each of the two fixed rods that are close to each other.

[0013] Furthermore, rectangular sliders are slidably connected inside both hollow rods, and springs are fixedly connected to the opposite sides of the two rectangular sliders. The opposite sides of the two springs are respectively fixedly connected to two fixed rods, and cutting blades are fixedly connected to the opposite sides of the two rectangular sliders. T-shaped grooves are provided on the rear sides of both fixed rods, and T-shaped sliders are fixedly connected to the rear inner wall of the fixed box. Both T-shaped grooves are slidably connected to the T-shaped sliders.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting an anti-reverse mechanism, the raw material gauze for the mask to be processed is placed on three circular rollers (1), then the gauze is passed between two circular rollers (2), and then placed between two cutting blades. The motor is then started. When the motor starts, the upper rotating shaft (3) will rotate. When the upper rotating shaft (3) rotates, the upper gear will also rotate. When the upper gear rotates, it will drive the lower gear to rotate simultaneously. When the lower gear rotates, the lower rotating shaft (3) will also rotate. At this time, the two rotating shafts (3) rotate in opposite directions through the transmission of the two gears. When the two rotating shafts (3) rotate in opposite directions, the two circular rollers (2) will also rotate in opposite directions. When the two circular rollers (2) rotate in opposite directions, they will exert a force to the left on the gauze. When the gauze is subjected to a leftward force, the first circular roller will rotate. When the first circular roller rotates, the first rotating shaft (1) will also rotate. When the machine is in motion, the ratchet will also rotate. When the ratchet rotates, the toothed block on it will lift the limit rod. When the limit rod is lifted up, it will rotate on the second rotating shaft. When the second rotating shaft rotates, the other end of the limit rod will descend. At this time, because the limit rod will have a certain arc when it descends, the slide bar will move the slider in the slide groove. When the limit rod falls, the fixed plate will also exert a downward pulling force with the spring. This pulling force will act on the fixed block. When the limit rod passes through the toothed block on the ratchet, the fixed block will be pulled up by the pulling force and contact the ratchet again. This achieves the prevention of the first roller from reversing or rotating too much. Under the restriction of the ratchet by the limit rod, the first roller is prevented from reversing or rotating too much, making the yarn output more uniform. This reduces the waste of resources caused by cutting errors due to yarn wrinkles.

[0016] 2. By setting up a cutting mechanism, the pulley rotates simultaneously with the lower rotating shaft three. The rotation of the pulley drives the rotating shaft four to rotate simultaneously via a belt. When the rotating shaft four rotates, the turntable also rotates. As the turntable rotates, the circular sliders slide within the elliptical groove. Due to the elliptical nature of the groove, the two circular sliders move towards and away from each other. When the circular sliders move, the fixed rods also move. When the two fixed rods move, the T-shaped groove restricts the movement of the fixed rods through the cutting blade, limiting their movement to either downwards or upwards. When the fixed rod moves, it carries the hollow rod along with it. When the two cutting blades come into contact with the gauze, they are squeezed together. As the two cutting blades are squeezed together, the rectangular slider slides inward and contracts within the hollow rod. When the two rectangular sliders slide inward, the spring is squeezed. After the gauze is cut, the two cutting blades move away from each other, thus achieving an effective cutting effect. This allows the cutting blades to cut at a perpendicular angle when they come into contact with the gauze. Perpendicular cutting ensures a neat cut and avoids slanted cuts or tears on the edges of the gauze during the cutting process, thereby improving the cutting quality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 As shown, this utility model is a disposable medical mask production equipment, including a fixed box 1. The fixed box 1 is equipped with an anti-reverse mechanism 2 and a cutting mechanism 3. A plurality of rotating shafts 211 are rotatably connected to the inner wall of the fixed box 1. The front sides of the plurality of rotating shafts 211 extend rotatably out of the fixed box 1. A circular roller 212 is fixedly connected to the outer wall of the plurality of rotating shafts 211. A ratchet 213 is fixedly connected to the extension of the plurality of rotating shafts 211. A plurality of rotating shafts 214 are fixedly connected to the front side of the fixed box 1. A limit rod 215 is rotatably connected to the outer wall of the plurality of rotating shafts 214. A plurality of fixing blocks 216 are fixedly connected to the front side of the fixed box 1. A sliding groove 217 is opened on the right side of the plurality of limit rods 215. A sliding rod 218 is slidably connected in the plurality of sliding grooves 217. A slider 219 is fixedly connected to the outer wall of the plurality of sliding rods 218. A slider 219 is fixedly connected to the top of the plurality of sliders 219. A fixed plate 2110 is fixedly connected to the top of several fixed plates 2110, and the top of several springs 2111 is fixedly connected to a fixed block 216. Two rotating shafts 2112 are fixedly connected to the inner wall of the fixed box 1. The front sides of the two rotating shafts 2112 extend to the outside of the fixed box 1. A circular roller 2113 is fixedly connected to the outer wall of the two rotating shafts 2112. Gears 2114 are fixedly connected to the extension of the two rotating shafts 2112. The two gears 2114 mesh with each other. A motor 2115 is fixedly connected to the front side of the fixed box 1. The output shaft of the motor 2115 is fixedly connected to the rotating shaft 2112 located on the upper side through a coupling. By setting an anti-reverse mechanism, the circular roller is prevented from reversing or rotating multiple times under the restriction of the ratchet by the limit rod, so that the yarn is output more evenly. This reduces the waste of resources due to cutting errors caused by wrinkles in the yarn.

[0030] The cutting mechanism 3 includes a rotating shaft 311 that rotatably passes through the front side of the fixed box 1. Pulleys 312 are fixedly connected to the front extension of the rotating shaft 311 and the lower extension of the rotating shaft 2112. A belt 313 is fixedly connected to the outer wall of each of the two pulleys 312. A turntable 314 is fixedly connected to the rear extension of the belt 313. An elliptical groove 315 is provided on the turntable 314. A circular slider 316 is slidably connected within the elliptical groove 315. A fixed rod 317 is fixedly connected to the rear side of each of the two circular sliders 316. A hollow rod 318 is fixedly connected to the side of each fixed rod 317 that is close to each other. A rectangular slider 319 is slidably connected within each of the two hollow rods 318. Two springs 3110 are fixedly connected to the opposite sides of the blocks 319. The opposite sides of the two springs 3110 are fixedly connected to two fixed rods 317 respectively. A cutting blade 3111 is fixedly connected to the opposite side of the two rectangular sliders 319. A T-shaped groove 3112 is opened on the rear side of the two fixed rods 317. A T-shaped slider 3113 is fixedly connected to the inner rear wall of the fixed box 1. The two T-shaped grooves 3112 are slidably connected to the T-shaped slider 3113. By setting the cutting mechanism, the cutting blade can cut at a vertical angle when it contacts the gauze. Vertical cutting can ensure a neat cut and avoid the gauze edge from being cut at an angle or torn during the cutting process, thereby improving the cutting quality.

[0031] A specific application of this embodiment is as follows: In use, first place the device in the appropriate position, then place the gauze material (the raw material for the mask) onto the three rollers 212. Next, pass the gauze between two rollers 2113, and then place the gauze between two cutting blades 3111. Then, start the motor 2115. When the motor 2115 starts, the upper rotating shaft 2112 will rotate accordingly. When the upper rotating shaft 2112 rotates, the upper gear 2114 will also rotate. When the upper gear 2114 rotates, it will cause the lower gear 2114 to rotate simultaneously. When the lower gear 2114 rotates, the lower rotating shaft 2112 will also rotate accordingly. At this time, the two rotating shafts 2112 are connected by the two gears 2111. The transmission of 4 involves opposite rotations. When the two rotating shafts 2112 rotate in opposite directions, the two rollers 2113 will also rotate in opposite directions. When the two rollers 2113 rotate in opposite directions, they will exert a force to the left on the yarn. When the yarn is subjected to a force to the left, the roller 212 will rotate. When the roller 212 rotates, the rotating shaft 211 will also rotate. When the rotating shaft 211 rotates, the ratchet 213 will also rotate. When the ratchet 213 rotates, the teeth on it will lift the limiting rod 215. When the limiting rod 215 is lifted, it will rotate on the rotating shaft 214. When the rotating shaft 214 rotates, the other end of the limiting rod 215 will descend. At this time, because the limiting rod 215 descends with a certain arc... The sliding rod 218 will cause the slider 219 to move within the groove 217. When the limiting rod 215 falls, the fixing plate 2110 will also exert a downward pulling force on the spring 2111. This pulling force will act on the fixing block 216. When the limiting rod 215 passes the toothed block on a ratchet 213, the fixing block 216, which is under tension, will be pulled up and contact the ratchet 213 again. This prevents the ratchet 213 from reversing or turning too much. When the lower rotating shaft 3112 rotates, the pulley 312 will also rotate. When the pulley 312 rotates, it will drive the rotating shaft 311 to rotate simultaneously through the belt 313. When the rotating shaft 311 rotates, the turntable 314 will also rotate. 4. When rotated, the circular slider 316 slides within the elliptical groove 315. Due to the elliptical nature of the groove 315, the two circular sliders 316 will alternately move closer and further apart. As the circular sliders 316 move, the fixed rod 317 also moves. When the two fixed rods 317 move, the T-shaped groove 3112 restricts the movement trajectory of the fixed rods 317 via the cutting blades 3111, limiting them to either downward or upward movement. The movement of the fixed rods 317 also moves the hollow rod 318. When the two cutting blades 3111 contact the gauze, they are compressed. When the two cutting blades 3111 are compressed, the rectangular slider 319 slides inward within the hollow rod 318 and contracts.When the two rectangular sliders 319 slide inward, the spring 3110 is compressed. After the gauze is cut, the two cutting blades 3111 move away from each other, thus achieving an effective cutting effect.
