Description

Technical Field

[0001] This invention relates to the field of mask production, specifically to a mask face folding device for a mask production line. Background Technology

[0002] A face mask is a hygiene and epidemic prevention product, generally worn over the mouth and nose to filter the air entering the mouth and nose, in order to block harmful gases, odors, droplets, viruses and other substances. It is made of materials such as gauze or paper. Face masks have a certain filtering effect on the air entering the lungs. Wearing a face mask is very effective when respiratory infectious diseases are prevalent or when working in dusty or polluted environments.

[0003] The mask production process includes: 1. Raw material selection: Selecting appropriate amounts of PP non-woven fabric, nose bridge strips, threads, antibacterial filter paper, activated carbon cloth, waterproof and breathable membrane, non-woven fabric edging material, and ear loops; 2. Mask production: Hanging the PP non-woven fabric raw materials, antibacterial filter paper, activated carbon cloth, and waterproof and breathable membrane on the mask making machine's material rack and adjusting the machine for automatic production; 3. Welding and shaping: Placing the nose bridge strip on top of the mask sheet, then folding the mask sheet and wrapping it around the nose bridge strip; 4. Inner packaging workshop: Sterilizing and disinfecting the formed masks and vacuum sealing them.

[0004] In the mask production process, the mask surface needs to be folded to reduce the packaging area of ​​the mask surface and make it easier to carry. Currently, the mask surface folding devices used on mask production lines tend to open up easily, resulting in poor shaping. When rolling up, the folded surface will wrinkle, causing the mask surface to be scrapped.

[0005] In view of this, we propose a mask face folding device for a mask production line to solve the problems existing in the current device. Summary of the Invention

[0006] The purpose of this invention is to provide a mask folding device for a mask production line to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 4The present invention provides a technical solution: a mask folding device for a mask production line, comprising a base 1, on which a first conveying pressure roller 2, a second conveying pressure roller 3, a take-up roller 4 and a support platform 5 are fixed. A folding mechanism is provided on the support platform 5, and a bracket plate 6 is also fixed on the upper surface of the support platform 5. A pressing and folding mechanism is provided on the bracket plate 6. An ironing mechanism is also provided between the second conveying pressure roller 3 and the take-up roller 4 and mounted above the base 1, forming an integral mask folding device structure for a mask production line.

[0026] In this embodiment, the pressing and folding mechanism includes a horizontal plate 7, a horizontal plate 8, a pressure rod 9, a lower pressure plate 10, an adjusting bolt 11, and a spring 12. The horizontal plate 7 and the horizontal plate 8 are fixed to the inner side of the support plate 6. The horizontal plate 8 is fitted with a pressure rod 9 that can be pulled up and down. The bottom end of the pressure rod 9 is fixed with the lower pressure plate 10. The horizontal plate 7 is threaded with the adjusting bolt 11, and the bottom end of the adjusting bolt 11 is against the top of the pressure rod 9. The pressure rod 9 is also fitted with a spring 12. The two ends of the spring 12 are fixed to the horizontal plate 8 and the lower pressure plate 10, respectively. The upper surface of the support platform 5 is also provided with a folding groove 26 with both ends pointing to the conveying pressure roller 2 and the conveying pressure roller 3. The lower pressure plate 10 is located directly above the folding groove 26 and is used to press and fold the mask surface.

[0027] In this embodiment, the folding mechanism includes two end plates 13, a pressure rod 14, a rubber extrusion sheet 15, an end plate 16, and a lever 17. The support platform 5 is fixed with two parallel end plates 13 at the end of the conveying pressure roller 3. A removable pressure rod 14 is inserted into the end plate 13. The inner end of the pressure rod 14 is fixed with a rubber extrusion sheet 15. The end of one of the end plates 13 is also fixed with an end plate 16. The inner side of the end plate 16 is fixed with a lever 17 to press the folded surface and then push it under the fabric to avoid squeezing and wrinkling the fabric at the folded part during winding, thus reducing the risk of the fabric being ruined due to wrinkles.

[0028] In this embodiment, the ironing mechanism includes a lower box 18, an upper box 19, an air supply pipe 20, and a flexible hose 21. The lower box 18 is mounted on the upper surface of the base 1, and the upper box 19, which can move up and down, is provided above the lower box 18. The lower box 18 and the upper box 19 are connected by the air supply pipe 20, and the flexible hose 21 is provided in the middle of the air supply pipe 20. Hot steam is used to iron the fabric, which further improves the forming effect and the stability of the fabric after folding.

[0029] In this embodiment, two side plates 22 are fixed on the side walls of the upper box 19 and the lower box 18. A limit rod 23 that can be pulled up and down is inserted into the side plate 22 of the upper box 19. The bottom end of the limit rod 23 is fixed to the corresponding side plate 22 of the lower box 18. A second spring 24 is also fitted on the limit rod 23. The lower end of the second spring 24 is fixed to the side plate 22 of the upper box 19, and the upper end of the second spring 24 is fixed to the end cap of the limit rod 23, which makes it convenient to lift the upper box 19. At the same time, the folded mask surface can be pressed between the two boxes for ironing.

[0030] In this embodiment, both the upper box 19 and the lower box 18 are hollow, and the bottom surface of the upper box 19 and the top surface of the lower box 18 are provided with a number of air vents 25, which can evenly spray hot steam to achieve the ironing effect.

[0031] In this embodiment, a spring 27 is also fitted on the pressure rod 2 14. One end of the spring 27 is fixed to the limiting plate on the pressure rod 2 14, and the other end of the spring 27 is fixed to the end plate 13. This allows the two pressure rods 2 14 to move closer to each other after the pressure rods 2 14 are released, so that the two rubber extrusion sheets 15 can be pressed against both sides of the fold, pressing them together to make the fold tightly stick together, increasing the stability after folding, preventing the fold from opening, and thus improving the molding effect.

[0032] In this embodiment, the thickness of the lower pressure plate 10 is less than the width of the folding groove 26 to avoid squeezing and damaging the mask fabric.

[0033] In this embodiment, the take-up roller 4 is driven by a motor to achieve automated take-up.

[0034] Invention and advantages: The mask folding device of this mask production line operates as follows:

[0035] Step 1: As Figure 2 As shown, the mask face to be folded is passed through the conveyor roller 1 2, conveyor roller 2 3, lower box 18 and upper box 19, and its end is wrapped around the take-up roller 4. When the mask face is placed between the lower box 18 and the upper box 19, the handle on the upper box 19 is held by hand and the upper box 19 is lifted. The spring 24 is compressed, and a gap is created between the upper box 19 and the lower box 18. The mask face is then passed through the gap between the two. Then the upper box 19 is released. The spring 24 uses its own elasticity to pull the upper box 19 down, thereby pressing the mask face between the two boxes.

[0036] Step 2: Rotate the adjusting bolt 11 downwards to press the pressure rod 9 downwards. The spring 12 is compressed, and the lower pressure plate 10 at the bottom of the pressure rod 9 presses the mask surface into the folding groove 26. The mask surface is recessed in the folding groove 26. Then connect the steam supply pipe to the air supply pipe 20 and send steam into the upper box 19 and lower box 18 under high pressure. The steam is sprayed onto the mask surface through the air outlet 25. Since the two boxes press the mask surface, the mask surface can be ironed when rolling it up.

[0037] Step 3: Turn on the motor driving the take-up roller 4, causing it to rotate. The take-up roller 4 pulls the mask surface from left to right, then pulls the two pressure rods 14 outwards, compressing the spring 27 and leaving a gap between the two rubber extrusion plates 15. When the mask surface is conveyed, the lower pressure plate 10 folds the mask surface. When the folded part slides out through the folding groove 26 on the support platform 5, the two pressure rods 14 are released. The spring 27 uses its own elasticity to press the rubber extrusion plates 15 at the inner ends of the two pressure rods 14 tightly against the folded part, allowing the fold to... The folds are pressed tightly together to increase stability after folding and prevent them from opening up, thus improving the forming effect. When the folds are rolled up with the pull tab 17 attached to them, the pull tab 17 pushes the folds to the bottom of the fabric, allowing them to overlap on the bottom of the fabric. This prevents the fabric at the folds from being squeezed and wrinkled during rolling, reducing the risk of the fabric being ruined due to wrinkles. The mask surface that has been pushed to the bottom is then rolled by the conveyor pressure roller 3 to increase flatness. When it passes through the ironing mechanism, it is ironed to further improve the forming effect and the stability of the fabric after folding.
