Description

Technical Field

[0001] The utility model relates to the technical field of mask production, in particular to a mask forming device. Background Art

[0002] Fine dust and harmful substances in the air enter the human respiratory tract, irritating and damaging the organ mucosa, reducing its ability to kill viruses and bacteria and prevent them from entering the lung tissue. This also reduces the tracheal mucosa's detoxification function, causing symptoms such as coughing and tracheitis in previously healthy people. People with respiratory diseases such as asthma, chronic bronchitis, and chronic obstructive pulmonary disease can develop lung infections, causing shortness of breath, chest tightness, wheezing, and other discomfort, leading to acute exacerbations.

[0003] With the outbreak of the epidemic, everyone needs to protect themselves and wear masks when traveling to isolate the virus from the outside world.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] The utility model provides a mask forming device, please refer to Figure 1-4 , including a base plate 100, a movable component 200, a welding component 300 and an ultrasonic positioning component 400;

[0030] Please continue reading Figure 1 , as a base support base bottom plate 100, the top of the bottom plate 100 is threadedly connected to a connecting frame 110, and the top of the bottom plate 100 corresponds to the two sides of the connecting frame 110 are screwed with slide rails 120;

[0031] Please continue reading Figure 1 、 Figure 3 and Figure 4 , the movable component 200 is connected to the connecting frame 110 and slides along the top of the bottom plate 100;

[0032] The movable component 200 includes a servo motor 210 threadedly connected to the outside of the connecting frame 110. The output end of the servo motor 210 is connected to a driving pulley 211. A transmission belt 212 is sleeved on the driving pulley 211. The other end of the transmission belt 212 is connected to a driven pulley 220. The driven pulley 220 is rotatably connected to the outside of the connecting frame 110.

[0033] The driven pulley 220 is connected to a screw rod 221 on the outside (the screw rod extends into the connecting frame), a threaded sleeve 230 is screwed onto the screw rod 221, and a bracket 231 that slides with the slide rail 120 is screwed onto the outside of the threaded sleeve 230. The top of the bracket 231 is connected to the mounting frame 240 via a positioning bolt.

[0034] action:

[0035] The servo motor 210 rotates, driving the linkage consisting of the driving pulley 211, the transmission belt 212, and the driven pulley 220. This in turn drives the screw rod 221 to rotate within the connecting frame 110. Since the threaded sleeve 230 is threadedly engaged with the screw rod 221, and the rotation direction of the threaded sleeve 230 is restricted by the slide rail 120 and the bracket 231, the screw rod 221 rotates, causing the mounting frame 240 to slide along the top of the base plate 100.

[0036] Please continue reading Figure 1-2 The welding component 300 is connected to the movable component 200 and moves synchronously with the movable component 200 to perform welding operations on the input material strip;

The front end of the connecting rod 341 is threadedly connected to the welding piece 350. A spring 342 is sleeved on the outer side of the connecting rod 341. The other end of the spring 342 is connected to the mounting bracket 240.

[0038] action:

[0039] The driving motor 320 works, driving the eccentric shaft 321 to rotate, and the eccentric rod 330 follows the eccentric shaft 321 to perform eccentric movement. However, due to the sliding cooperation and limitation between the connecting seat 340 and the slider 311, when the eccentric shaft 321 rotates, the eccentric rod 330 drives the welding piece 350 to move back and forth, and the welding operation is performed through the welding piece 350.

[0040] Please continue reading Figure 1 An ultrasonic positioning component 400 is connected to the outside of the mounting frame 240. The ultrasonic positioning component 400 includes a fixing frame 410 connected to the outside of the mounting frame 240. An ultrasonic generator 420 is installed in the fixing frame 410. An ultrasonic positioning head 421 is connected to the outside of the fixing frame 410. The ultrasonic positioning head 421 is arranged corresponding to the welding piece 350.

[0041] Working principle: When the utility model is in use, the servo motor 210 drives the linkage composed of the active pulley 211, the transmission belt 212 and the driven pulley 220 to rotate, and drives the screw rod 221 to rotate synchronously, so that the mounting frame 240 slides along the top of the base plate 100. At the same time, the drive motor 320 drives the eccentric shaft 321 to rotate, and the eccentric rod 330 follows the eccentric shaft 321 to perform an eccentric movement, so that the eccentric rod 330 drives the welding piece 350 to move back and forth, and the welding operation is performed through the welding piece 350, ensuring that the translation and welding are synchronized, and there will be no leakage of materials or welding.
