Description

Mask machine

The present invention relates to a "mask machine" that can produce self-adhesive masks without ear hooks.

According to the current known flat or three-dimensional masks, most of them have a mask body, which is made of non-woven fabric with an ear strap connected to each side. Pulling the two ear straps out will enable the mask body to unfold smoothly. When the ear straps are hooked on the user’s ears, the mask can be worn to prevent germs or contaminated air from being sucked into the body through the mask’s isolation and filtration .

However, the above-mentioned conventional structure still has the following problems in practical application: (1) If the conventional mask is a general or medical flat mask, the problem of poor adhesion often occurs, if it is N95 The three-dimensional mask, because the mask needs to be pressed tightly, will cause breathing difficulties and facial discomfort after long-term wear; (2) The mask needs to be additionally combined with ear straps and worn Those with nose bridge strips, so the production cost is high, and the speed is relatively slow; (3) The ear straps will cause ear discomfort after wearing, and the three-dimensional design of the N95 mask will also cause inconvenience in carrying.

Therefore, the inventor of the present invention is in view of this, thinking and creating ideas, and then designed with years of experience, after many discussions and trial samples, and many modifications and improvements, the present invention was introduced.

It is known that masks have poor adhesion and will cause ear discomfort after wearing. This is the technical problem to be solved.

The mask machine of the present invention is composed of a feeding unit, a forming unit, a spraying unit, a release paper inserting unit, a mask finishing unit and a packaging unit which are connected in sequence to form a complete earless The production line for hanging self-adhesive masks, and the production of the mask machine includes roll feeding, folding forming, ultrasonic roll welding, hob punching, spraying, release paper insertion, hob cutting, and separating The steps of cutting off the paper hob, discharging defective products, folding the finished product in half, transferring the finished product, sealing film/printing and packaging, etc., among which the feeding unit has several placement sections arranged in the upper and lower layers, and each placement section has It is provided with a central axis that can be used to wrap the entire roll of mask material. When the mask material passes through the guide frame and the traction device of the feeding unit in sequence, the traction device is used to press the mask materials of each layer When they are together, the pressed mask materials can be continuously conveyed in the direction of the forming unit to smoothly complete the roll feeding step of the mask machine. The forming unit has a folding part and an ultrasonic wave. The seam welded part and a hob perforated part. The folded part is used to fold the mask material after pressing into the required wrinkles, so that the width of the mask material can also be generated by the wrinkles From the width to the narrower, the ultrasonic seam welding part uses ultrasonic waves to compress and produce the wrinkles of the various layers of mask materials to heat and fuse them together, so as to be self-adhesive in each can be produced without ear hooks A full circle of hot melt lines of the required shape are formed on the mask, and the hob punching part is used in the hob The mask raw material is provided with several positioning holes arranged along the length of the mask raw material near the two sides, so as to use the folds, hot melt lines and positioning holes to be formed on the mask raw material in order to complete the mask machine The steps of folding forming, ultrasonic seam welding and hob punching, etc., the glue spraying unit has a recirculating conveyor belt. The two sides of the conveyor belt are provided with several positioning posts arranged along its length. The positioning pillars are inserted into the positioning holes of the mask raw materials one by one, and drive the mask raw materials to move in the direction of the release paper inserting unit, so that the mask raw materials can be accurately positioned during the glue spraying process, so as to avoid going The two sides are offset from the conveyor belt, and above the conveyor belt is equipped with a number of nozzles that can follow the conveyor belt to run, so as to return to the origin after running, and each nozzle is used to separately As soon as the earhook-free self-adhesive mask can be produced as spray glue, a circle of adhesive that can be used for bonding when used is formed on the inner side of the hot melt line. This way To complete the glue spraying step of the mask machine, the release paper inserting unit uses the rolling member to roll the release paper to the side of the mask material with the backing glue to do the bonding, so that the release paper is used to match The adhesive is used for covering, and the release paper inserting step of the mask machine can be completed. The mask finishing unit has a cutting part and a quality control area. The cutting part is equipped with a hob and uses the hob edge Cut the mask material and release paper according to the shape required by the ear-hook self-adhesive mask, so as to remove the excess part containing the positioning holes, and then the hob of the mask machine can be completed The cutting step and the cutting step of the release paper hob, and the cutting part is also provided with a rotating shaft and a reeling wheel, so that the cut waste can be guided by the rotating shaft and gradually be rolled by the roll In the reeling and reel collection, the quality control area has an inspection electric eye at the end of the entire production line, and a baffle and a folding plate that can be controlled by the electric eye. The baffle and the folding plate are separate in normal state. In the state of descending and ascending, the finished self-adhesive mask without earhooks can be stopped by the baffle, and a short stay under the electric eye will occur. When the electric eye detects the earless When the self-adhesive mask is defective, it will immediately control the baffle Defective products can be discharged from below the baffle, and the folded plate can be controlled to lower after the electric eye detects that the earless self-adhesive mask is a good product, so that the earless self-adhesive mask The sticky mask can be folded in half by the folding plate from the middle, and conveyed in the direction of the packaging unit through the channel below. According to this process, the defective product discharge, the finished product folded in half and the finished product transfer can be completed. The packaging unit uses a packaging machine to package and print the finished product of the ear-less self-adhesive mask, so as to complete the production of the entire ear-less self-adhesive mask after the sealing/printing and packaging steps; In this way, it is possible to constitute the mask machine.

(1) In the mask machine of the present invention, the close-fitting of the ear-less self-adhesive mask after wearing is not completed by compression, and the medical-grade pressure-sensitive adhesive is used for comprehensive sealing, which can make the ear-less self-adhesive mask Adhesive masks have both comfortable wearing and excellent facial fit.

(2) In the mask machine of the present invention, the ear-hook-free self-adhesive mask does not need to be combined with ear straps or nasal bridges during production, so the production cost is low and the production is faster. .

(3) In the mask machine of the present invention, the ear-less self-adhesive mask is only the size of a normal credit card after being folded in half, and there is no need to wear a nose bridge, which can also make the ear-less self-adhesive mask easier to fold , In order to achieve the specific effect of convenient carrying.

(4) In the mask machine of the present invention, the ear-hook-free self-adhesive mask does not need to be worn with ear straps, so it can avoid discomfort to the ears after wearing.

(5) In the mask machine of the present invention, the ear-hook-free self-adhesive mask can completely cover the mouth and nose after unfolding, and an air chamber is formed inside, so as to achieve a large effective filtration area, a small pressure difference, and smooth breathing The use.

(6) In the mask machine of the present invention, the nozzle can spray glue while moving in circles, so as to greatly improve the production efficiency, and it can be returned immediately after glue spraying to achieve a continuous and uninterrupted cycle of action.
