Description

Automatic device for efficiently producing safe easily-torn mask and production method thereof

Technical Field

The invention relates to the field of machinery, in particular to an automatic device for efficiently producing a safe and easily-torn mask and a method for producing the mask.

Background

The mask is a powerful tool for people to deal with environmental air pollution, prevent respiratory diseases and particularly prevent and control epidemic diseases, and in the prior art, a complete mask product is produced, and the production method of the mask product is summarized as follows:

the first step is as follows: mask body production: the mask comprises non-woven fabric, a middle filter layer, a nose bridge iron strip and a skin-friendly fabric, wherein the non-woven fabric, the middle filter layer, the nose bridge iron strip and the skin-friendly fabric are laminated, shaped and flattened to form a mask body (also called a mask sheet).

The second step is that: cutting off and hemming the mask body: the preparation is made for welding the ear-hang, the equipment is automatically completed, and manual intervention is not needed.

The third step: welding ear area, welding ear area can occupy more time, and production efficiency is lower, so among the prior art, can adopt a gauze mask body production line + two ear area welding line's mode (commonly known as one drags two) to solve the efficiency matching problem, lead to the production facility complicated, area is big, and semi-automatic or artifical line then needs one to many workers to accomplish the welding ear area, and production efficiency is lower, has wasted more resources for labor.

The fourth step: transferring and disinfecting the mask: the disinfection needs to be carried out in a special gas disinfection room, the mask needs to be transported to the disinfection room from a production line, at least one or more workers are needed to finish the disinfection according to different yields, and the time (generally 7-14 days) for 'analysis' after the mask is disinfected and sterilized is time-consuming, labor-consuming and labor-consuming.

The fifth step: transferring and packaging the mask: after the mask is disinfected and analyzed, the mask is transferred to a packaging line, the packaging is divided into two types of manual packaging and automatic packaging, one or more workers are needed for manual packaging according to the output scale, at least one worker is needed for automatic packaging, one mask to be packaged is placed into a flow packaging machine, the packaging work is completed, time, labor and labor are consumed, and secondary pollution of the mask is easily caused.

In summary, the prior art methods for producing masks have the following disadvantages: 1) the production links are multiple, the production equipment is complex, and the occupied area is large; 2) large manual consumption (at least 3 or more, even dozens of production line workers are needed in the whole line); 3) the secondary pollution of the mask is easily caused, and the quality of the product is reduced.

A method of producing a mask comprising the steps of:

the first step is as follows: material sterilization and disinfection: in the production process of the traditional mask, the disinfection is uniformly carried out after the finished product is processed,

generally, the sterilizing gas is used for fumigating in a closed space, but because the gas has carcinogenic effect, a finished product after the sterilization needs to be placed for 7-10 days, the process is called as 'analysis', and the product is hermetically packaged after the 'analysis' is finished, so that a complete and qualified mask product is formed.

The invention adjusts the disinfection and sterilization process to the raw material supply stage, the raw material supplier is responsible for completing the process, the raw materials are supplied to the mask production unit in the form of sterile package, and the mask production unit only needs to ensure the dust-free condition of the production workshop, thus shortening the production, storage and shipment periods of products, and particularly avoiding the secondary pollution of the mask products.

The second step is that: processing a mask body: the mask comprises a skin-friendly fabric 101, a middle filter layer 102, a nose bridge strip 103 and a non-woven fabric 104, which are laminated, shaped and flattened to form a continuous strip-shaped mask body 106, the process is the same as that of the prior art, and the existing production equipment can be adopted, as shown by a dotted line frame in figure 1.

The following steps are the significant differences between the invention and the prior art:

the third step: forming an outer surface film: the outer cover 301 is roll pressed using a hot roll press die to form the outer cover 301 into a grooved, contoured, ear-hang outer cover 302 having a groove depth of about half the thickness of the outer cover, and remaining intact and unbroken to form the tear line 13, as shown in fig. 2 c.

The fourth step: comprehensive film covering: the inner surface film 201 is pressed by ultrasonic wave or hot roller pressing mode or harmless gluing technology, so that the inner surface film 201 is covered and adhered on the inner surface of the mask body 106, and meanwhile, the outer surface film 302 with the ear hanging outline of the groove-shaped structure is pressed, so that the outer surface film 302 is covered and adhered on the outer surface of the mask body 106.

The fifth step: cutting a finished product: the mask strip 107 covered with the inner and outer masks is cut and cut to form a complete and independent mask finished product, and the finished product is automatically put into a finished product storage box 8, as shown in fig. 1.

Or, including press-cut easy-tear holes: the connecting position of the gauze mask covered with the inner film and the outer film and the gauze mask is cut into easy-to-tear holes similar to stamp holes by adopting a cutting and pressing or rolling mode, so that the gauze mask and the gauze mask are kept in a state of 'if disconnected, continuously disconnected', not only are the gauze masks connected, but also the gauze masks are easy to tear.

Further, the method also comprises the following steps of printing an image-text trademark: and printing characters and patterns such as trademarks, specifications and the like on the surface of the finished mask product by adopting a code-spraying printing or laser device.

Further, automatic winding is also included; the mask produced in the above way is rolled into toilet paper rolls, and stored in rolls according to a preset number or stored in a Z-shaped laminated manner.

The steps are based on the requirements of physical space and character description, and in the actual production process, the steps are synchronously performed by machine line production, and can be regarded as simultaneous steps and completion in time.

To further understand the present invention, the following description is made in a complete and reverse order from the point of view of the use of the mask product.

When in use, a finished mask is taken out or a mask is torn off from a mask roll as shown in fig. 9 a.

As shown in fig. 9a and 9b, a tear is poked along the tear line 13 of the outer membrane with a slight finger force, and the excess 14 is torn off (shown in phantom in fig. 9 b), leaving the elastic mask ear loop 12.

As shown in fig. 10, the elastic mask ear hook 12 is pulled to both sides to expose the mask outer surface 15.

As shown in fig. 11, the inner surface film is torn off from the back side of the mask to expose the mask skin-friendly surface 16, which is a human body contact surface, and the mask is prevented from contacting the hand after being torn off, so that pollution is prevented.

The mask is worn according to the specified front and back sides, and the mask is tightly combined with the face of a human body by the elastic acting force of the ear hook 12 of the elastic mask, so that the protective effect of the mask is realized.

In summary, the statistics of the occupied human resources of the mask production method are shown in the left side of the following table, and the statistics of the occupied human resources of the prior art are shown in the right side of the following table.
