Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an automatic feeding and welding device for mask ear loops. Background Technology

[0002] A face mask is a hygiene and epidemic prevention product, generally worn over the mouth and nose to filter the air entering the mouth and nose, thereby blocking harmful gases, odors, droplets, viruses, and other substances. It is made of materials such as gauze or paper. After the initial production of the mask sheet, the two ear loops need to be welded to the mask sheet to form a mask. The existing ear loop welding equipment is not fully automated. Usually, there is no automatic feeding of the mask sheet, and the welding of the ear loops also requires manual length setting and feeding, followed by welding. Announcement No. CN212422231U discloses a mask ear loop welding machine, comprising: a base on which a mask body is horizontally placed; a wire preparation mechanism including a first wire clamp and a second wire clamp, both capable of clamping the mask ear loops and sliding in the left-right direction; a clamping mechanism capable of clamping both ends of the mask ear loops and transferring them above the mask body; a wire cutting mechanism for cutting the mask ear loops; a welding mechanism capable of moving vertically and welding the cut mask ear loops to the mask body; and a baffle vertically disposed on the base in the left-right direction and located between the two clamps, wherein the mask ear loops clamped by the two clamps can wrap around part of the baffle as the clamps move. This device cannot automatically feed mask pieces and can only weld ear loops on one side of the mask, indicating insufficient automation. Utility Model Content

[0037] In this embodiment, the mask ear loop welding process is as follows: First, mask bodies are fed one by one from the feeding plate 15. The mask bodies slide downwards on the feeding plate 15 at an angle until they fall to the feeding end of the first conveyor belt 11. Then, the first conveyor belt 11 is started, and the first conveyor belt 11 conveys the mask bodies one by one until they are conveyed to the discharge end of the first conveyor belt 11.

[0038] At this time, the first servo motor 14 and the first lifting cylinder 16 are started respectively. The first servo motor 14 drives the first screw to rotate, thereby driving the feed seat 121 and the vacuum suction cup 13 to move back and forth. The piston rod of the first lifting cylinder 16 extends and retracts, thereby driving the vacuum suction cup 13 to move up and down, so that the vacuum suction cup 13 moves the mask body from the first conveyor belt 11 to the second conveyor belt 21 one by one, specifically moving it between the two adjacent partition plates 211 of the second conveyor belt 21.

[0039] Then start the second conveyor belt 21 until the second conveyor belt 21 transports the mask body to the set position directly below the bracket 2a;

[0040] At this time, the two unwinding motors 28 are started. The unwinding motors 28 drive the unwinding rollers 281 to unwind the ear belt. Then, after the ear belt passes the fixing block 265 of the fixing cylinder 264, it moves to the second pneumatic finger 262 and is clamped by the second pneumatic finger 262. Then, the third conveyor belt 266 is started to drive the two sliding seats 261 to move until they move to the set position.

[0041] At this time, the two propulsion cylinders 271 are activated, and the piston rods of the propulsion cylinders 271 retract to pull the cutting blade 272 to close, so that the cutting blade cuts the ear loops. Then, the two first pneumatic fingers 224 are activated, and the two first pneumatic fingers 224 on the same side clamp the two ends of the ear loops respectively. Then, the two rotary cylinders 223 on the same side are activated to drive the first pneumatic fingers 224 to rotate, so that the ends of the ear loops are aligned with the mask body.

[0042] At this point, the two supporting cylinders 29 are activated first, and the piston rods of the supporting cylinders 29 extend to drive the welding base 291 to move upward until the welding base 291 just supports the part of the mask body that needs to be welded to the ear loops. Then, the stepper motor 23 is activated, and the stepper motor 23 drives the cam 231 to rotate, which drives the first swing arm 222 to swing up and down, thereby driving the first lifting seat 221 to move up and down, and driving the first pneumatic finger 224 to move up and down, until the two ends of the ear loops are moved to the part of the ear loops to be welded, and the two ends of the ear loops are in contact with the part of the mask body that needs to be welded. Then, the two second lifting cylinders 24 are activated, and the piston rods of the second lifting cylinders 24 extend to drive the lifting frame 25 and the welding head 251 to move downward until the pressing plate 253 presses down on the mask body. The return spring 252 is compressed, and the lifting frame 25 continues to move downward until the welding head 251 contacts the ear loops, so that the welding head 251 and the welding base 291 cooperate to weld the two ends of the ear loops to the mask body.
