Description

Technical Field

[0001] The invention belongs to the field of automatic processing, and in particular relates to an automatic processing device for masks. Background Art

[0002] There are many types of masks on the market, including flat masks, vertical masks, cup masks, folding masks, etc., and there are also many types of equipment for producing masks. At present, most masks produced by the mask manufacturing industry are manually made or semi-automatically produced. A mask requires three to four processes to be made into a finished product, and the process is quite complicated and cumbersome. Moreover, masks are produced using a simple combination of equipment, with high labor costs and low production efficiency, especially the upper belt is generally welded by staff manually, which is labor-intensive.

[0003] For example, the comparative document 1 with patent application number "202010267917.3" discloses a mask ear strap welding device, including a feeding device, a conveying device, a welding device and an ear strap conveying device, the feeding device and the conveying device are arranged in sequence from back to front, the feeding device includes a separation mechanism and a feeding mechanism, the separation mechanism separates the stacked mask bodies individually, and the separated individual mask bodies are sent to the conveying device by the feeding mechanism, the conveying device transports the mask body to the welding device, and at the same time takes the mask body with the ear strap welded away from the welding device, the ear strap conveying device transports the ear strap to the welding device and welds the ear strap to the mask body through the welding device. In the comparative document 1, there is a separate mask ear strap welding device, which needs to first produce the mask body, and then manually place the produced mask body on the device for further ear strap welding. Although the welding device uses machine welding, it reduces the work intensity of workers; however, when the mask is produced by this device and the corresponding mask body production device, the two processes of mask body production and ear strap welding cannot be well combined and unified, and the ear straps cannot be welded while producing the mask body, which makes the mask production efficiency relatively low and cannot be further improved.

[0004] For example, the comparative document 2 of the patent application number "202010132519.0" provides a one-machine-multiple-one-molding mask machine and its mask, including a fabric processing mechanism, which is connected in sequence according to the processing order, including a fabric shaping pleating device, a nose bridge line conveying device, a shaping cutting device, an ultrasonic welding device, a flattening device, a cutting device and a conveying device; the above devices are provided with two processing channels vertically arranged in parallel with an upper and lower double layer, and the shaping cutting device directly extrude the shape of the ear strap through cutting and ultrasonic welding devices. The one-machine-multiple-one-molding mask machine and its mask of the present invention can mold two masks at the same time. The present invention reduces the welding of the ear strap line, and there is no ear strap line reel. The ear strap directly uses a cutting device to cut the shape of the ear strap and directly extrude the ear strap of the mask through the extrusion die of the ultrasonic welding device. The non-woven elastic fabric is directly used as the ear strap, and the corresponding ear strap structure is removed, which reduces the volume of the entire machine and equipment and improves the processing efficiency. In the comparative document 2, although the shaping and cutting device directly extrude the shape of the ear strap through cutting and ultrasonic welding device when producing the mask, which solves the problem that the mask body production and ear strap production in the above-mentioned comparative document 1 cannot be carried out simultaneously on the same device; however, in the comparative document 2, the shaping and cutting device of the mask machine directly extrude the shape of the ear strap through cutting and ultrasonic welding device. In this process, not only cutting but also ultrasonic welding are required to extrude the shape of the ear strap, which is very cumbersome. In addition, due to the addition of the shaping and cutting device, the size of the mask machine is larger and the overall structure is more complicated. It is easy to malfunction during long-term production and processing, affecting production efficiency. Summary of the invention

[0005] In order to solve the above problems, the primary purpose of the present invention is to provide an automatic mask processing device, which can perform ear strap welding while producing masks, and the device has a simple structure and is not prone to malfunction during the production and processing of masks, which can make production efficiency higher.

[0006] Another object of the present invention is to provide an automatic mask processing device, which can perform automated production after the materials are manually placed and pulled, while reducing the workers' workload and the number of workers required, and having higher production efficiency.

The above-mentioned ear band material is the material used to make the ear band; the mask material is the material used to make the semi-finished mask, such as non-woven fabric, melt-blown fabric, etc. In the device, the mask material is gradually driven and transported in the processing operation channel, and is processed during the transportation process, wherein the ear band material is cut off at the ear band cutting assembly after shaping and falls on the mask material. The specific processing process is as follows: the mask material passes through the mask folding assembly, is folded and pressed, and is welded and fixed by the mask welding assembly to form a semi-finished mask product. The ear band material is folded and shaped by the ear band shaping assembly and then cut and split by the ear band cutting assembly. When the semi-finished mask product passes through the ear band cutting assembly, the cut ear band material falls on the semi-finished mask product, and the ear band material is welded to the semi-finished mask product through the ear band welding assembly.

[0012] Furthermore, one or more ear band diversion rollers are provided between the ear band shaping assembly and the ear band cutting assembly for pulling the ear band material to divert the ear band material from the mask material. The arrangement of the ear band diversion rollers allows the ear band material to be diverted from the mask material before entering the ear band cutting assembly, and does not affect the processing of the mask material.
