Description

Technical Field

[0001] The utility model relates to the technical field of mask production, in particular to a conveying device for mask nose strips. Background Technique

[0002] A mask is a hygiene product, generally referring to an appliance worn over the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose, and is made of gauze, paper, etc.

[0003] Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent or when working in a polluted environment such as dust, wearing a mask has a very good effect. When medical staff treat patients, they mostly use masks to isolate the respiratory tract to protect the health of medical staff. Currently, medical staff mostly use N95 masks and their similar types. As a key component for mask sealing, the mask nose strip is of indispensable significance for the sealing performance of the mask.

[0004] When preparing the nose strip, three steps of feeding, cutting, and discharging are required, and three flow devices are used simultaneously, resulting in a large floor area of the equipment. Moreover, the structural design of the production line will lengthen the conveying time of the raw materials and affect the work efficiency. Summary of the Utility Model

[0030] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the implementation mode of the present utility model in detail in conjunction with the accompanying drawings.

[0031] The present utility model provides a conveying device for a mask nose bridge strip. Please refer to Figures 1-4 , including a support 100, a cutter component 200, a push plate component 300 and an idler wheel component 400;

[0032] Please continue to refer to Figure 1 , Figure 2 and Figure 4, as the bracket 100 connecting to the base frame, a guide wheel frame 110 is integrally formed and connected to the outside of the bracket 100. A guide wheel 111 is rotatably connected to the guide wheel frame 110. The guide wheel 111 is used for auxiliary guiding and conveying of the nose bridge strip. The top of the bracket 100 is connected to a connecting frame 120 through a positioning bolt. A guide seat 121 is connected to the outside of the connecting frame 120, and a guide frame 130 is connected to the top of the bracket 100. The connecting frame 120 serves as the connecting base frame of the cutter component 200. The guide seat 121 is used for guiding the movement direction of the sliding frame 221, and the guide frame 130 is used for guiding the movement direction of the push plate 332;

[0033] Please continue to refer to Figures 1-2 , the cutter component 200 is connected to the connecting frame 120 to cut the input nose bridge strip;

[0034] The cutter component 200 includes a driving motor 210 threadedly connected to the outside of the connecting frame 120. The output end of the driving motor 210 is connected to an eccentric shaft one 211. The end of the eccentric shaft one 211 is connected to an eccentric rod one 220.

The bottom of the sliding frame 221 is connected to a cutter 222 through a positioning bolt;

[0035] Action:

[0036] The driving motor 210 works, driving the eccentric shaft one 211 to rotate. The rotation of the eccentric shaft one 211 cooperates with the eccentric rod one 220, causing the sliding frame 221 to perform an eccentric action. However, since the sliding frame 221 is limited by the guide seat 121, when the eccentric rod one 220 acts, the sliding frame 221 drives the cutter 222 to move up and down to cut the input nose bridge strip;

[0037] Please continue to refer to Figure 3 , the push plate component 300 is placed on the bracket 100, corresponding to the end of the cutter component 200, and pushes out the cut nose bridge strip;

The front end of the sliding frame 331 is threadedly connected to a push plate 332. The push plate 332 moves back and forth along the inside of the guide frame 130;

[0039] Action:

[0040] The servo motor 320 operates to drive the second eccentric shaft 321 to rotate. The second eccentric shaft 321 drives the second eccentric rod 330 to perform an eccentric motion, causing the slide block 311 to move horizontally along the top of the slide frame 331, and then driving the push plate 332 to move back and forth to push out the cut nose strip.

[0041] Please continue to refer to Figure 1 , the guide wheel assembly 400 is installed on the bracket 100 to convey the nose strip.

[0042] The guide wheel assembly 400 is connected to the bracket 100, including a motor 410 threadedly connected to the outside of the bracket 100. The output end of the motor 410 is connected to the driving wheel 411. The driving wheel 411 is rotatably connected to the bracket 100. And two sets of driven wheels 412 are symmetrically rotatably connected to the bracket 100. Both sets of driven wheels 412 are in meshing transmission cooperation with the driving wheel 411. A transmission wheel 420 is rotatably connected above the two sets of driven wheels 412 on the bracket 100. The transmission wheel 420 is in meshing transmission cooperation with the driven wheels 412. Feed rollers 431 are connected to the outside of the transmission wheel 420 and the driven wheels 412 through connecting rods respectively.

And the transmission wheel 420 is in meshing transmission cooperation with the driven wheels 412, so the transmission wheel 420 rotates synchronously, and then drives the upper and lower corresponding feed rollers 431 to rotate to convey the input nose strip to the cutting tool assembly 200.

[0045] Please continue to refer to Figure 1 , a pressing component 500 is connected to the bracket 100. The pressing component 500 includes a fixing frame 510 connected to the outside of the bracket 100. An adjusting rod 511 is screwed on the top of the fixing frame 510. The bottom end of the adjusting rod 511 is connected to a pressing plate 512. A spring 520 is connected to the bottom of the pressing plate 512. The bottom end of the spring 520 is connected to a slider 530. The slider 530 is slidably connected inside the fixing frame 510.

[0046] Working principle: When the utility model is in use, the motor 410 drives the linkage gear set composed of the driving wheel 411 and the driven wheels 412 to rotate, so that the upper and lower corresponding feed rollers 431 rotate to convey the input nose strip to the cutting tool assembly 200. And the driving motor 210 drives the first eccentric shaft 211 to rotate, which cooperates with the first eccentric rod 220 to make the sliding frame 221 drive the cutting tool 222 to move up and down to cut the input nose strip. At the same time, the servo motor 320 drives the second eccentric shaft 321 to rotate. The second eccentric shaft 321 drives the second eccentric rod 330 to perform an eccentric motion, causing the slide block 311 to move horizontally along the top of the slide frame 331, and then driving the push plate 332 to move back and forth to push out the cut nose strip.
