[0038] The technical scheme in this embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in this embodiment of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments of the present invention. Based on this embodiment of the present invention, all other embodiments of the present invention obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 12 An embodiment of the present invention provides a facial mask folding device. In this embodiment, a facial mask folding device of an embodiment of the present invention is used to automatically fold a pearlescent film hydrogel facial mask product whose mask base film is a pearlescent film and whose gel body is a hydrogel.

[0040] A facial mask folding device according to an embodiment of the present invention comprises a frame 1 and a conveyor belt 2 mounted on the frame 1, a first folding strip 3 for folding one end of a facial mask is mounted on one side above the conveyor belt 2, a second folding strip 4 for folding the other end of the facial mask is mounted on the other side, a first width-fixing strip 5 for determining the folding width of one end of the facial mask when one end of the facial mask is folded is mounted on one side of the first folding strip 3, a first limiting strip 7 for limiting the one end of the facial mask when the folding of one end of the facial mask is completed is mounted on one side of the first width-fixing strip 5, a second width-fixing strip 6 for determining the folding width of the other end of the facial mask when the other end of the facial mask is folded is mounted on one side of the second folding strip 4, and a second limiting strip 8 for limiting the other end of the facial mask when the folding of the other end of the facial mask is completed is mounted on one side of the second width-fixing strip 6.

[0041] The above-mentioned mask folding device also includes two pressing rollers 10 installed at one end above the conveyor belt 2 and used to press down and pre-tighten the mask when the mask enters the conveyor belt 2, a first pressing strip 11 installed on one side of the first limiting strip 7 and used to pre-tighten one end of the mask after one end of the mask is folded, a second pressing strip 12 installed on one side of the second limiting strip 8 and used to pre-tighten the other end of the mask after the other end of the mask is folded, and a pressing mechanism installed at one end between the first pressing strip 11 and the second pressing strip 12 and used to press the folded mask into shape.

[0042] The first folding strip 3, the second folding strip 4, the first width-fixing strip 5, the second width-fixing strip 6, the first limiting strip 7, the second limiting strip 8, the first pressing strip 11 and the second pressing strip 12 are stainless steel wires of different shapes respectively.

[0043] The frame 1 includes a first cross bar 15 installed below one end of the conveyor belt 2, a second cross bar 16 installed above one end of the conveyor belt 2, and a third cross bar 17 installed above one end of the clamping mechanism.

[0044] One end of the first folding strip 3 and the second folding strip 4 are respectively mounted on the first crossbar 15, and the first position adjustment plate 30 and the second position adjustment plate 40 are respectively mounted on the third crossbar 17. The other end of the first folding strip 3 is mounted on the first position adjustment plate 30, and the other end of the second folding strip 4 is mounted on the second position adjustment plate 40. The first position adjustment plate 30 can adjust the position and angle of the first folding strip 3, and similarly, the second position adjustment plate 40 can adjust the position and angle of the second folding strip 4. The first position adjustment plate 30 and the second position adjustment plate 40 are used together to adjust the flanging track and effect of the two ends of the mask.

[0045] The two pressing rollers 10 are respectively equipped with connecting rods 100, and the two connecting rods 100 are respectively installed on the second cross bar 16. The connecting rods 100 are used to adjust the position of the pressing roller 10. The function of the pressing roller 10 is to pre-apply a downward pressing force to the mask when the mask initially enters the conveyor belt 2. The pressing force is small, which can make the smooth bottom of the mask fully contact with the conveyor belt 2, allowing the mask to continue to move forward, and finally allowing the mask to be folded smoothly.

[0046] A first fixed width position adjustment component 50 is installed at one end of the first fixed width strip 5, and the first fixed width position adjustment component 50 is installed at one end of the frame 1. A second fixed width position adjustment component 60 is installed at one end of the second fixed width strip 6, and the second fixed width position adjustment component 60 is installed at the other end of the frame 1. The first fixed width position adjustment component 50 and the second fixed width position adjustment component 60 each include a transverse adjustment knob 55 for adjusting the transverse distance and a longitudinal adjustment knob 56 for adjusting the longitudinal distance. The first fixed width position adjustment component 50 and the second fixed width position adjustment component 60 can respectively quickly adjust the folding width at both ends of the mask through the transverse adjustment knob 55, and adjust the folding effect at both ends of the mask through the longitudinal adjustment knob 56. Among them, the advantages of the transverse adjustment knobs 55 of the first fixed width position adjustment component 50 and the second fixed width position adjustment component 60 are: it is convenient for the mask folding device to quickly change the production of masks with different folding widths, quickly meet the needs of users for masks with different folding widths, greatly reduce the equipment adjustment time, greatly improve production efficiency, and quickly respond to customer customization needs. Specifically, an example is given as follows: for example, customer A needs to customize 1,000 type A facial masks with a folding width of 20 mm at both ends, and customer B needs to customize 50 facial mask samples with a folding width of 15 mm at both ends and 1,000 type B facial masks with a folding width of 30 mm at both ends. The facial mask folding device can manually adjust the lateral adjustment knob 55 of the first fixed-width position adjustment component 50 and the second fixed-width position adjustment component 60 to quickly switch the production of masks with different folding widths, and the adjustment time can be controlled within one minute.

[0047] One end of the first limiting strip 7 is mounted on one end of the frame 1, and the other end thereof is mounted with a third position adjustment plate 70, which is mounted on the third cross bar 17. One end of the second limiting strip 8 is mounted on the other end of the frame 1, and the other end thereof is mounted with a fourth position adjustment plate 80, which is mounted on the third cross bar 17. When both ends of the mask are folded, the first limiting strip 7 and the second limiting strip 8 prevent the folded edges at both ends of the mask from recovering and deforming.

[0048] A first pressing position adjusting component 110 is installed at one end of the first pressing strip 11, and the first pressing position adjusting component 110 is installed at one end of the frame 1. A second pressing position adjusting component 120 is installed at one end of the second pressing strip 12, and the second pressing position adjusting component 120 is installed at the other end of the frame 1. The first pressing position adjusting component 110 and the second pressing position adjusting component 120 each include a longitudinal mounting groove 76 installed on the frame 1 by bolts and a transverse adjustment rod 75 for adjusting the transverse distance. The first pressing position adjusting component 110 and the second pressing position adjusting component 120 can respectively adjust the pre-pressing distance of the two ends of the folded mask through the transverse adjustment rod 75, and adjust the pressing effect of the two ends of the mask through the longitudinal mounting groove 76. The functions of the first pressing strip 11 and the second pressing strip 12 are: to pre-press the two ends of the mask after the two ends of the mask are folded, to prevent the height of the two ends of the folded mask from recovering and expanding, thereby avoiding failure of the two ends of the mask to enter the pressing mechanism.

[0049] A driving roller 24 is installed at one end of the conveyor belt 2, and a driven roller 25 is installed at the other end. One end of the driving roller 24 is transmission-connected to a first driving assembly 26.

[0050] The pressing mechanism is set as a belt pressing mechanism 9, which includes a pressing and forming belt 90 installed above the conveyor belt 2, a first tensioning roller 91 installed at one end of the pressing and forming belt 90, a second tensioning roller 92 installed at the other end of the pressing belt, and a second driving assembly 93 for transmission connection with one end of the first tensioning roller 91. The pressing and forming belt 90 is installed at one end between the first pressing strip 11 and the second pressing strip 12. The first tensioning roller 91 and the second tensioning roller 92 are respectively provided with height adjustment assemblies 94 at both ends. The first tensioning roller 91 and the second tensioning roller 92 can adjust the tensioning width of the pressing and forming belt 90, and the two adjust the pressing height between the pressing and forming belt 90 and the conveyor belt 2 through the height adjustment assembly 94. When the folded facial mask is transported to the pressing and forming belt 90, the pressing and forming belt 90 will press the facial mask to form it, and the pressing and forming belt 90 will move synchronously with the conveyor belt 2 to transport the pressed facial mask out. In this embodiment, the first drive component 26 and the second drive component 93 are respectively synchronous wheel and synchronous belt transmission components, and the synchronous wheel and synchronous belt transmission components are driven by a motor. In other embodiments, the first drive component 26 and the second drive component 93 are respectively driven by a motor or a sprocket chain. In short, the first drive component 26 and the second drive component 93 are power elements for transmitting rotational power.

[0051] In this embodiment, the conveyor belt 2 includes a first conveyor belt 21, a second conveyor belt 22 arranged parallel to the first conveyor belt 21, and a plurality of small belts 23 installed between the first conveyor belt 21 and the second conveyor belt 22 and used to increase the friction force at the middle bottom of the mask when conveying the mask. In other embodiments, the conveyor belt 2 can be any long strip that can convey the mask. Since there are many types of long strips, the structure and composition of the long strip of the conveyor belt 2 are not limited in the present invention.

[0052] like Fig.11 As shown, Fig.11 Schematic diagram of the structure of the facial mask of the prior art when it is not folded; Fig.12 As shown, Fig.12 This is a schematic diagram of the structure of a facial mask in the prior art after being folded.

[0053] A facial mask folding device according to an embodiment of the present invention has the following working steps for automatically folding a facial mask:

[0054] S1: The mask enters the conveyor belt 2, and the pressing roller 10 is pressed on the top surface of the mask by its own weight. At this time, the pressing roller 10 has a light weight and will not damage the top surface of the mask. At the same time, the mask is in full contact with the conveyor belt 2, and the conveyor belt 2 smoothly conveys one end of the mask between the first folding strip 3 and the first fixed-width strip 5, and conveys the other end of the mask between the second folding strip 4 and the second fixed-width strip 6;

[0055] S2: the first folding strip 3 is in contact with the bottom of one end of the mask, the first width-fixing strip 5 is in contact with the top of one end of the mask, the first folding strip 3 and the first width-fixing strip 5 together complete the function of folding one end of the mask, and the shape of the first folding strip 3 is the folding forming track of one end of the mask;

[0056] S3: Similarly, the second folding strip 4 contacts the bottom of the other end of the mask, and the second width-fixing strip 6 contacts the top of the other end of the mask. Because one end of the mask needs to be folded before the other end of the mask can be folded, the front end shape of the second folding strip 4 is flatter than the front end shape of the first folding strip 3. The purpose is that the front end of the second folding strip 4 does not fold. After the first folding strip 3 is folded, the second folding strip 4 starts to fold the other end of the mask. Therefore, after the first folding strip 3 completes the folding of one end of the mask, the second folding strip 4 and the second width-fixing strip 6 jointly complete the function of folding the other end of the mask. The shape of the second folding strip 4 is the folding forming track of the other end of the mask;

[0057] S4: After folding is completed, the first limiting strip 7 abuts against the top of the folded edge at one end of the mask to prevent the size of the folded edge from recovering and deforming. Specifically, the folded edge is limited to prevent it from recovering, warping or bulging and other unstable recovery deformations. Similarly, the second limiting strip 8 abuts against the top of the folded edge at the other end of the mask. The function of the second limiting strip 8 is the same as that of the first limiting strip 7.

[0058] S5: After folding is completed, the first pressing strip 11 pre-presses one end of the mask, and the second pressing strip 12 pre-presses the other end of the mask. The first pressing strip 11 and the second pressing strip 12 are used to allow the folded mask to enter the pressing mechanism smoothly.

[0059] S6: After the folded facial mask enters the belt pressing mechanism 9 of the pressing mechanism, the folded facial mask is pressed and formed by the pressing and forming belt 90 of the belt pressing mechanism 9, and the pressing and forming belt 90 moves synchronously with the conveyor belt 2 to transport the pressed facial mask out. At this time, the automatic folding of the facial mask is completed.

[0060] It is specially noted that the mask folding device of the above-mentioned embodiment comprises a first folding strip 3 and a second folding strip 4, which form a folding order of the two ends of the mask due to their three-dimensional structure. However, the mask folding device of the present invention does not limit the left and right folding order of the first folding strip 3 and the second folding strip 4. The mask can be folded at the left end first and then at the right end, or at the right end first and then at the left end, which can be installed and determined according to the actual needs of the customer.

[0061] A facial mask folding device according to an embodiment of the present invention can realize an automatic facial mask folding function, with high folding efficiency, high facial mask yield and consistent facial mask folding quality.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
