Preferably, the upper plate is composed of a straight plate and a plurality of horizontally L-shaped bent plates stacked in sequence, and the lower plate is integrally bent along the upper plate by a single plate. Its continuous bending section and the inner bending section are formed.

Preferably, the angle between the selvage turning passage and the pleating passage is greater than 90 degrees on the inlet side, and the selvedge turning passage and the wrinkling passage are approximately parallel and spaced at the outlet side.

The above objects and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of the following selected embodiments.

First of all, please refer to Figures 1 to 4, a flat mask forming device provided in this creation, which is mainly composed of a template body 10, which is used for continuous folding and pressing of mask fabrics to form the required The body of the plane mask, including:

The template body 10 is in the shape of a hollow shell that is permeable on both sides, and has an inlet side 11 and an outlet side 12 sequentially arranged along a conveying direction X of the mask fabric 41 , and an inlet side 11 and an outlet side 12 located in the template body 10 On the two sides 13 and 14 of the two opposite sides, the mask fabric 41 enters the template body 10 from the inlet side 11 , and is folded through the preset shape inside the template body 10 , and then is output from the outlet side 12 . To the next process (such as setting nose line and hot pressing), and further, the inlet side 11 is outwardly expanded to form a trumpet-shaped extension section 111 on both sides facing the two side edges 13 and 14, and has a usable The function of guiding the input direction of the mask fabric 41 is used.

The formwork body 10 is composed of an upper plate 21 and a lower plate 31 that are stacked on top of each other in a spaced manner, wherein the upper plate 21 and the lower plate 31 are welded by means of welding (as shown by the dotted square in the figure). position) are overlapped and joined together, and the two side edges 13, 14 are tapered gradually approaching each other in the direction from the inlet side 11 to the outlet side 12 (that is, equivalent to the conveying direction X), so that The width of the outlet side 12 is smaller than the width of the inlet side 11 . The upper plate 21 and the lower plate 31 are respectively formed with continuous bending sections 22 and 32 corresponding to each other at the central positions along the conveying direction X. , so that a pleated channel 15 in a continuous bending shape is formed between the upper plate 21 and the lower plate 31, so that the mask fabric 41 entering the pleated channel 15 through the inlet side 11 can be placed in the mask fabric 41. After folding up several corrugated portions 42 extending along the conveying direction X, they are then shrunk and output by the outlet side 12 with a smaller width. There is a pressure strip 23 facing the entrance side 11 and extending outward, and each pressure strip 23 is used to relatively press against the mask fabric 41 that is about to enter the entrance side 11, so that the mask fabric 41 can first enter the entrance side 11. Pressed by each of the pressing bars 23 , it is slightly curved to form a continuous bending shape corresponding to the shape of the corrugated channel 15 .

The portion of the lower plate 31 located on one side 13 of the formwork body 10 laterally protrudes from the upper plate 21 and is bent upward to form an inner folded section 33 , and the inner folded section 33 is along the conveying direction X It leans toward the upper plate member 21 in a gradually folded downward shape, so that a selvage folded channel 16 can be additionally formed inside the inner folded section 33 . Preferably, the upper plate 21 is composed of a straight plate 211 and a plurality of laterally L-shaped bent plates 212 stacked in sequence, and the lower plate 31 is composed of a single plate along the upper plate. The part 21 is integrally bent and superimposed to form its continuous bending section 32 to ensure the supporting strength of the lower plate part 31, and then the inner bending section 33 is formed by bending upward at its extending end, and the selvedge is folded. The angle between the channel 16 and the corrugated channel 15 is greater than 90 degrees on the inlet side 11, and the selvage folded channel 16 and the corrugated channel 15 are arranged at a parallel interval on the outlet side 12, so that the mask located on the lower layer is When the fabric 41 passes through the selvage turning channel 16 , it can gradually perform an inward folding action along the selvage turning channel 16 toward the upper plate member 21 .

Next, please continue to refer to Fig. 4. In practical application, the flat mask forming device provided by this creation uses a feeding unit 51 composed of several conveying rollers to convey along the conveying sequence in a predetermined stacking sequence. The direction X continuously transports the multi-layer mask fabrics 41 to the template body 10, so that each layer of mask fabrics 41 can enter the interior of the template body 10 through the inlet side 11 of the template body 10 at the same time. At this time, several pleats 42 extending along the conveying direction will be folded along the shape of the pleating channel 15, and the mask fabric 41 located on the lower layer will pass through the edge folding channel 16. At the same time, it is folded inward along the shape of the cloth edge folding channel 16, so that the flat mask forming device provided by the present invention can form the wrinkled parts 42 in each layer of mask cloth 41, and also complete the positioning. It is very practical to work on the folded edge of one side of the mask fabric 41 of the lower layer.

In the present invention, by integrating the functions of forming the corrugated portion 42 and turning the selvedge on the template body 10 at the same time, not only can the composition structure of the automatic manufacturing equipment for flat masks be effectively simplified, so as to reduce the overall volume, and at the same time Because the actions of forming the wrinkled portion 42 and turning the selvedge are carried out at the same time, setting errors can be effectively avoided, and the deviation between the wrinkled portion 42 of the mask and the turning selvedge can be reduced, thereby greatly improving product manufacturing. In order to effectively solve the problems of low production efficiency and low product yield of the existing flat mask automatic manufacturing equipment.

However, the disclosure of the above embodiments is only used to illustrate the present creation, not to limit the present creation, so any changes in numerical values or replacement of equivalent components should still belong to the scope of the present creation.

To sum up, to make it clear to those who are familiar with the art that this creation can indeed achieve the above-mentioned purpose, it is in compliance with the provisions of the Patent Law, so the application is filed in accordance with the law.
