Description

Technical Field

[0001] This application relates to the technical field of medical device production equipment, and particularly to a mask earband welding device. Background Art

[0002] Masks are daily necessities frequently used in people's daily lives. The structure of masks on the market mainly includes the following:

[0003] Outer layer (waterproof layer): Its main function is to block splashing liquids, such as water droplets, saliva, etc., to protect the wearer from being contaminated by external liquids. It is usually made of materials with good waterproof performance, such as waterproof non-woven fabric.

[0004] Middle layer (filter layer): It is the core part of the mask, which can effectively block particles in the air, such as bacteria, viruses, dust, etc., to protect the respiratory health of the wearer. The middle layer is usually made of melt-blown cloth, which is a special treated polypropylene fiber material with a high filtration efficiency.

[0005] Inner layer (water-absorbing layer): Its function is to absorb the water vapor exhaled by the wearer's mouth and nose, keep the inside of the mask dry and comfortable, and avoid discomfort caused by dampness during long-term wearing. It is usually made of soft, comfortable and water-absorbent materials, such as cotton non-woven fabric.

[0006] Nose clip: Located above the mask, it is used to adjust according to the shape of the wearer's nose bridge to ensure the tight fit between the mask and the face and improve the protection effect. It is generally made of an environmentally friendly all-plastic strip, without any metal, and is comfortable to wear.

[0007] Earband: It is used to fix the mask on the wearer's ears. It is usually made of materials with good elasticity to ensure that the mask is firmly worn and not easily fallen off.

[0008] Among them, the welding of the earband is relatively complex. It is necessary to cut the earband into appropriate lengths and then accurately weld the ends at the four corners of the mask. The operator needs to cut the rolled mask earband into appropriate lengths, then place the two ends of the cut mask earband at the corresponding positions of the mask body, and weld the two ends of the mask earband to the mask body respectively by operating the welding machine. This welding method of the mask earband has low production efficiency, high labor cost and is not safe to operate. Utility Model Content

[0057] An embodiment of this application provides a mask earband welding device, including a conveying platform 10, an earband pulling part 20, a cutting part 30, a clamping part 40, and a welding part 50, where:

[0058] The conveying platform 10 includes a base plate 11 and a conveyor belt 12 arranged on the base plate 11. The base plate 11 is used to install the conveyor belt 12, as well as the earband pulling part 20, the cutting part 30, the clamping part 40, and the welding part 50.

[0059] The earband pulling part 20 includes a sliding mechanism, a fixed gripper 24, and a movable gripper 23. The sliding mechanism is arranged on the base plate 11. The movable gripper 23 is connected to the sliding mechanism, and the fixed gripper 24 is fixed on one side of the sliding mechanism. The sliding mechanism can drive the movable gripper to approach or move away from the fixed gripper 24. Both the fixed gripper 24 and the movable gripper 23 can perform the actions of grasping and releasing the earband 60. One earband pulling part 20 is arranged on each side of the conveyor belt 12, and the two earband pulling parts 20 are symmetrically arranged with each other and are respectively used to correspondingly grasp the two earbands 60 on the mask.

[0060] The cutting part 30 includes two scissors 32 which are respectively arranged between the fixed grippers 24 and the movable grippers 23 of the two strap parts 20, and the scissors 32 are close to the fixed grippers 24. The scissors 32 are used to cut the ear straps 60 so as to cut the ear straps 60 into the lengths required for making masks.

[0061] The clamping part 40 includes a lifting bracket 41, a steering mechanism 42 and a clamping forceps 43. The steering mechanism 42 is connected to the lifting bracket 41, the clamping forceps 43 are arranged and connected to the lower end of the steering mechanism 42, and the clamping forceps 43 are located between the fixed gripper 24 and the movable gripper 23; the lifting bracket 41 can drive the steering mechanism 42 to move up and down, the steering mechanism 42 can drive the clamping forceps 43 to rotate, and the clamping forceps 43 can perform the actions of clamping and releasing the ear straps 60. The number of the steering mechanisms 42 is four, and the four steering mechanisms 42 are distributed in pairs on both sides of the conveyor belt 12 respectively. A clamping forceps 43 is connected to the lower end of each steering mechanism 42, and the two forceps on the same side are used to correspondingly clamp the two ends of the ear straps 60 on the same side.

[0062] The welding part 50 includes a vertical frame 51, a lifting mechanism 52 and a welding head 53. The lifting mechanism 52 is connected to the vertical frame 51, the welding head 53 is connected to the bottom end of the lifting mechanism 52, the welding head is located above the conveyor belt 12, and the lifting mechanism 52 can drive the welding head 53 to move in the vertical direction. The number of the welding heads 53 is four, and the four welding heads 53 are distributed in pairs on both sides of the conveyor belt 12 respectively. The two welding heads 53 on the same side are used to correspondingly weld the two ends of the ear straps 60 on the same side to the mask.

[0063] Working process: The raw materials of the ear straps 60 are set in a roll. The head end of the ear strap 60 passes through the fixed gripper 24, and the part of the ear strap 60 close to the head end is clamped by the fixed gripper 24 to prevent the head end of the ear strap 60 from falling. When the equipment is running, the sliding mechanism drives the movable gripper 23 to approach the fixed gripper 24, and the movable gripper 23 clamps the head end of the ear strap 60. Then, the fixed gripper 24 is released. After the sliding mechanism drives the movable gripper 23 to move away from the fixed gripper 24 by a certain distance, the fixed gripper 24 clamps the ear strap 60. At this time, a section of the ear strap 60 is grabbed between the fixed gripper 24 and the movable gripper 23.

[0064] Start the scissors 32 so that the scissors 32 cut one side of the earloop 60 near the fixed gripper 24, forming an earloop 60 with a certain length. At the same time, the lifting bracket 41 drives the two clamping tweezers 43 to quickly move downward and clamp near both ends of the earloop 60. Then the movable gripper 23 also releases, and the turning mechanism 42 drives the clamping tweezers 43 to rotate towards the conveyor belt 12, so as to fold both ends of the earloop 60 above the mask placed on the conveyor belt 12. Then the lifting mechanism 52 drives the welding head 53 to press down, making both ends of the earloop 60 closely adhere to the mask and starting welding, thereby welding the earloop 60 to the mask. Then, each part resets, and the conveyor belt 12 conveys the welded mask downstream, and at the same time conveys the mask without the welded earloop 60 to the welding station, and then performs the above series of operations to realize the automatic welding of the earloop 60.

[0065] Through the mask earloop welding device of the embodiment of the present application, operations such as manual cutting and placing of the earloop 60 are eliminated, the welding efficiency of the mask earloop 60 can be improved, the labor cost can be reduced, and the welding process of the mask is also made safer.

[0066] Specifically, the sliding mechanism includes a slide rail 21 and a slide seat 22 arranged on the slide rail 21, and the movable gripper 23 is connected to the slide seat 22. Each movable gripper 23 includes a claw-type cylinder, and the clamping tweezer 43 includes a finger cylinder and a tweezer handle arranged on the finger cylinder.

[0067] In the embodiment of the present application, the cutting part 30 further includes a suspension 31. The suspension 31 is located above the conveyor belt 12. The scissors 32 are connected to the suspension 31 and the direction of the cutting edge is downward. Two blocking strips 33 are provided at the bottom end of the suspension 31. The two blocking strips 33 are respectively located above both sides of the conveyor belt 12. The blocking strips 33 are used to prevent the mask from tilting and ensure that the mask is neatly placed on the conveyor belt 12.
