Description

Technical Field

[0001] This invention relates to a mask conveying device, and more particularly to a finished product conveying device for mask production. Background Technology

[0002] A face mask is a hygiene protective product used to protect the respiratory system from harmful substances such as smog, exhaust fumes, dust, and germs. It is generally worn over the mouth and nose to filter the air entering the mouth and nose, blocking harmful gases, odors, and droplets from entering or exiting the wearer's mouth and nose. Face masks have a certain filtering effect on the air entering the lungs, and are very effective during respiratory infectious disease outbreaks or when working in dusty or polluted environments.

[0003] After the masks are produced, the next step is to count and package them. Currently, most mask counting is done manually, but manual counting is prone to errors. In addition, if the conveying equipment does not fold the ear loops during the conveying process, multiple ear loops will obstruct each other when the masks are taken out, resulting in the remaining masks being carried out or becoming messy and inconvenient to take out.

A sliding support frame 214 is fixedly connected to the lower end of the fixed rods 215. A sliding groove is opened inside the sliding support frame 214. The first slider 212 is slidably connected in the sliding groove.

[0027] like Figure 6As shown, a mask base folding mechanism 3 is provided inside the housing 1 and on the right side of the bottom support column 201. The mask base folding mechanism 3 includes several support rods 301, which are fixedly connected inside the housing 1. Each support rod 301 is a cuboid with one end protruding. A frame 302 is fixedly connected to the upper surface of the support rod 301. A fixed seat 304 is fixedly connected to the lower surface of one end of the frame 302. A feeding plate 320 is fixedly connected to the end of the frame 302 near the fixed seat 304. A second drive shaft 311 is rotatably connected inside the fixed seat 304. A limit support plate 321 is rotatably connected to the middle of the second drive shaft 311. The two sides of the limit support plate 321 are connected to the fixed seat 304. Two inner sides are fixedly connected. A second pulley 312 is fixedly connected to the end of the second drive shaft 311. A first drive belt 207 is sleeved between the second pulley 312 and the first pulley 208. The diameter of the first pulley 208 is larger than that of the second pulley 312. When the drive is in progress, the mask root ear folding mechanism and the mask counting and collecting mechanism can be decelerated and linked. A worm gear 317 is fixedly connected to the other end of the second drive shaft 311. A worm 310 is rotatably connected to the side of the frame 302 near the fixed seat 304. The worm 310 has helical teeth between the two conveyor belts and smooth round rods at both ends. The two ends of the worm 310 pass through the frame 302. The worm gear 317 and the worm 310 are meshed and connected.

[0028] like Figure 7 As shown, sleeves 308 are rotatably connected to both ends of the worm gear 310 outside the frame 302. The sleeves 308 fix and support the worm gear 310. Both ends of the worm gear 310 pass through the sleeves 308 and are respectively fixedly connected to the ends of the sleeves 308. The other side of the two second transmission plates 307 is rotatably connected to the transmission rods 305 via a rotating shaft. The bottom surface of the middle part of the two transmission rods 305 is fixedly connected to the lifting plate 306. The other end of the frame 302 away from the worm gear 310 is rotatably connected to the belt shaft 318. Both ends of the belt shaft 318 pass through the frame 302. The ends of the two transmission rods 305 away from the worm gear 310 are also rotatably connected to the second transmission plates 307 via a rotating shaft. The other end of the second transmission plates 307 is fixedly connected to the belt shaft 318. The two ends of the belt shaft 318 are rotatably connected to the sleeves 308 and both ends of the belt shaft 318 pass through the sleeves 308. Two conveyor belts are sleeved between the belt shaft 318 and the worm gear 310. The conveyor belts are used to transport the finished masks.

[0029] A motor base 403 is fixedly connected to the upper right side of the housing 1 on the support rod 301. A synchronous motor 401 is installed inside the motor base 403. The motor base 403 serves to fix and support the synchronous motor 401. One end of the belt shaft 318 is fixedly connected to a third pulley 309 between the sleeve 308 and the second transmission plate 307. A second transmission belt 402 is sleeved between the third pulley 309 and the output shaft of the synchronous motor 401.

[0030] like Figure 7 , Figure 8 As shown, a portal frame 303 is fixedly connected to the middle of the frame 302. A claw-shaped support frame 313 is fixedly connected to one side of the portal frame 303. The four claws of the claw-shaped support frame 313 are located at one end close to the frame. The other end of the claw-shaped support frame 313 away from the portal frame 303 is fixedly connected to the frame 302. An inclined plate 319 is fixedly connected to one side of the claw-shaped support frame 313. The inclined plate 319 makes it easier for the mask ear loops to enter a state completely perpendicular to the mask. A sliding groove is opened at the lower end of the claw-shaped support frame 313. A push plate 316 is slidably connected inside the sliding groove. Springs are fixedly connected between the two ends of the push plate 316 near the frame 302 and the claw-shaped support frame 313. A limiting sliding groove is opened in the middle of the frame 302. A second slider 314 is slidably connected inside the sliding groove. The lower surface of the second slider 314 contacts the upper surface of the lifting plate 306. An arc-shaped inclined block 315 is fixedly connected to the side of the second slider 314.

[0031] First, the mask production equipment 4 is started. The mask production equipment 4 produces finished masks and conveys them onto the conveyor belt of the ear-folding mechanism 3 at the base of the mask. Then, the synchronous motor 401 is started, driving the belt shaft 318 to rotate. The belt shaft 318, through the attached conveyor belt, drives the worm gear 310 to rotate, achieving horizontal conveying of the masks. After the mask moves along the conveyor belt to the edge of the inclined plate 319, the ear loops rise continuously along the inclined surface of the inclined plate 319. When the mask reaches the rectangular surface of the claw-shaped support frame 313, the ear loops are in a completely vertical state. The belt shaft 318 and the worm gear 310 drive the second transmission plate 307 to rotate, which in turn drives the transmission rod 305 to rotate. The lifting plate 306 rotates, and the up-and-down reciprocating motion of the lifting plate 306 drives the second slider 314 to reciprocate up and down. When the second slider 314 moves upward, it drives the arc-shaped inclined block 315 to rise while squeezing the push plate 316 out of the groove and stretching the spring between the push plate 316 and the claw-shaped support frame 313. The push plate 316 pushes the ear loops to fold towards the middle of the upper surface of the mask and covers the mask. When the lifting plate 306 drives the second slider 314 to fall, the second slider 314 drives the arc-shaped inclined block 315 to fall. When the arc-shaped inclined block 315 falls, the spring pulls the push plate 316 to retract. After the push plate 316 retracts, the pressure on the mask disappears, and the mask continues to move forward with the conveyor belt.

[0032] The worm gear 310 drives the worm wheel 317 to rotate, and the worm wheel 317 drives the second pulley 312 to rotate via the second transmission shaft 311. The second pulley 312 drives the first pulley 208 to rotate via the first transmission belt 207, and the first pulley 208 drives the first transmission shaft 209 to rotate at a reduced speed, thus realizing the speed reduction linkage between the two mechanisms. The first transmission shaft 209 drives the first transmission plate 210 to rotate, and the first transmission plate 210 drives the slide rod 211 to rotate via the rotating shaft. The slide rod 211 drives the first slider 212 to slide horizontally in the sliding groove inside the sliding support frame 214.

[0033] The first slider 212 drives the teeth fixedly connected to the surface to move horizontally. According to the calculated transmission ratio, the teeth mesh and slide with the spur gear 213. After the meshing ends, the spur gear 213 will rotate 180 degrees. The spur gear 213 drives the connecting column 205 to rotate, the connecting column 205 drives the rotating seat 203 to rotate, and the rotating seat 203 drives the collection box 204 to rotate below the conveying plate 320. Then, the teeth of the first slider 212 disengage from the spur gear 213, the collection box 204 stops rotating and begins to collect masks. After enough masks are collected in the collection box 204, the first slider 212 drives the teeth to retract to the meshing position with the spur gear 213. The teeth continue to retract, driving the spur gear 213 to rotate 180 degrees in the opposite direction, rotating the full collection box 204 to the other end, realizing the alternation of empty and full collection boxes. The lever 217 on one side of the collection box 204 with full masks is lifted upward, and the masks rise with the lever 217, realizing the quick removal of quantitative masks.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
