[0026] Reference Figures 1 to 3 The mask folding mechanism of some embodiments of the first aspect of the present invention comprises a base frame 100 which is generally in the shape of a flat plate. The shape of the base frame 100 can be any shape, such as a rectangular parallelepiped, a cylindrical shape or other irregular shapes, etc., which can be determined according to actual needs. A first folding seat 110 is arranged on the base frame 100. A first folding groove 111 is provided on the upper surface of the first folding seat 110. A first plug-in 112 is movably arranged above the first folding groove 111. The first plug-in 112 is connected to a first driving mechanism which can drive it to move away from or insert into the first folding groove 111. The first The driving mechanism is arranged on the base frame 100. Of course, the first driving mechanism is fixedly arranged on other supporting surfaces, which is also possible. For example, the first driving mechanism is arranged on the ground, which can be determined according to actual needs. A second folding seat 120 is arranged on the base frame 100, and a second folding groove 121 intersecting with the first folding groove 111 is opened on the second folding seat 120. The second folding groove 121 runs through the first folding seat 110 and is connected to the inside of the first folding groove 111. A second plug-in 122 is movably arranged on one side of the second folding groove 121, and the second plug-in 122 is connected with a plug-in that can drive it to move far The second driving mechanism is separated from or inserted into the second folding groove 121, and the second driving mechanism is arranged on the base frame 100. Of course, the second driving mechanism is arranged on a supporting surface such as the ground, and it is also possible, and it is not limited to being arranged on the base frame 100. The base frame 100 is also provided with a third folding seat 130 located on one side of the second folding seat 120, and the third folding seat 130 is provided with a third folding groove 131 intersecting with the second folding groove 121. The third folding groove 131 runs through the second folding seat 120 and is connected to the inside of the second folding groove 121. One side of the third folding groove 131 is movably provided with The third plug-in 132 is connected to a third driving mechanism that can drive it to move away from or insert into the third folding groove 131. The third driving mechanism is arranged on the base frame 100. Of course, the third driving mechanism can also be arranged on a supporting surface such as the ground, which can be determined according to actual needs; a notch 123 is opened on one side wall of the second folding seat 120, which is adjacent to the intersection of the second folding groove 121 and the third folding groove 131. The notch 123 is arranged at one end of the second folding seat 120 away from the second plug-in 122, and a splicing plate 124 is detachably installed at the notch 123.

[0027] Reference Figure 1 and Figure 3When the mask paper needs to be folded in half, the splicing plate 124 can be removed from the notch 123. At this time, the notch 123 is in a naked state, so the mask paper (not shown in the figure) can be transported to the top of the first folding seat 110, and the one-quarter position of the mask paper is aligned with the second folding groove 121. At this time, the first driving mechanism drives the first plug-in 112 to move downward and push the mask paper into the first folding groove 111, and then the second driving mechanism drives the second plug-in 122 to be inserted into the first folding seat 110 and aligned with the one-quarter position of the mask paper. After that, the second plug-in 122 continues to move and pushes the mask paper located in the first folding groove 111 into the second folding groove 121 until the mask paper is folded in half. The middle half of the mask paper is aligned with the third folding groove 131. Since the second plug-in 122 is aligned with the quarter position of the mask paper and pushes the mask paper into the second folding groove 121, the part of the mask paper folded in the second folding groove 121 is just exposed at the notch 123. Since the mask paper itself has a certain elasticity, the part of the mask paper folded in the second folding groove 121 automatically opens under the action of its own elasticity. Then the third driving mechanism drives the third plug-in 132 to insert into the second folding seat 120 and push the mask paper in the second folding groove 121 into the third folding groove 131, and then the mask paper is folded in half in the third folding groove 131, that is, the mask paper is folded in half.

[0028] If the mask paper needs to be folded into three, the splicing plate 124 can be installed in the gap 123. At this time, the gap 123 is blocked and the second folding groove 121 is in a completed state. Therefore, the mask paper (not shown in the figure) can be transported to the top of the first folding seat 110, and the one-third position of the mask paper is aligned with the second folding groove 121. At this time, the first driving mechanism drives the first plug-in 112 to move downward and push the mask paper into the first folding groove 111, and then the second driving mechanism drives the second plug-in 122 to be inserted into the first folding seat 110 and aligned with the one-third position of the mask paper. The second plug-in 122 continues to move and pushes the facial mask paper in the first folding groove 111 into the second folding groove 121 until two-thirds of the facial mask paper is aligned with the third folding groove 131. At this time, the facial mask paper is folded by one-third in the second folding groove 121. Then the third driving mechanism drives the third plug-in 132 to insert into the second folding seat 120 and pushes the facial mask paper in the second folding groove 121 into the third folding groove 131. During this process, the third plug-in 132 is aligned with two-thirds of the facial mask paper and makes the facial mask paper fold again in the third folding groove 131, thereby realizing the three-fold of the facial mask paper.

[0029] If the mask paper needs to be folded into four, the splicing plate 124 can be installed in the gap 123. At this time, the gap 123 is blocked and the second folding groove 121 is in a completed state. Therefore, the mask paper (not shown in the figure) can be transported to the top of the first folding seat 110, and the half position of the mask paper is aligned with the second folding groove 121. At this time, the first driving mechanism drives the first plug-in 112 to move downward and push the mask paper into the first folding groove 111, and then the second driving mechanism drives the second plug-in 122 to be inserted into the first folding seat 110 and aligned with the half position of the mask paper. After that, the second plug-in 1 22 continues to move and pushes the facial mask paper in the first folding groove 111 into the second folding groove 121 until the position of one-half of the folded facial mask paper is aligned with the third folding groove 131. At this time, the facial mask paper is folded once in the second folding groove 121. Then the third driving mechanism drives the third plug-in 132 to insert into the second folding seat 120 and pushes the facial mask paper in the second folding groove 121 into the third folding groove 131. During this process, the third plug-in 132 is aligned with the one-half of the folded facial mask paper and makes the facial mask paper folded once again in the third folding groove 131, thereby realizing four folds of the facial mask paper.

[0030] By opening a notch 123 on one side wall of the second folding seat 120, which is adjacent to the intersection of the second folding groove 121 and the third folding groove 131, when the mask paper needs to be folded into three or four parts, the splicing plate 124 can be installed at the notch 123 to achieve the folding of the mask paper into three or four parts. If the mask paper needs to be folded into two parts, it is only necessary to remove the splicing plate 124. This is simple and convenient, and realizes the folding of the mask paper into two, three or four parts on the same mask folding mechanism, which helps to reduce the production cost of the enterprise.

[0031] Reference Figure 1 In order to make the structure of the mask folding mechanism simpler and easier to manufacture, in some embodiments of the first aspect of the present invention, the second folding seat 120 is arranged on the base frame 100 along a direction perpendicular to the first folding seat 110, and the second folding groove 121 is perpendicular to the first folding groove 111. By adopting the above structure, the second folding seat 120 and the first folding seat 110 are arranged on the base frame 100 more simply and compactly, and the second plug-in 122 is inserted into the second folding groove 121 more smoothly and is not easy to get stuck.

[0032] Furthermore, the third folding seat 130 is arranged parallel to one side of the first folding seat 110, and the third folding groove 131 is perpendicular to the second folding groove 121. By adopting the above structure, the layout of the third folding seat 130 and the second folding seat 120 is more compact, and the third plug-in 132 can be inserted into the third folding groove 131 more smoothly.

[0033] In order to simplify the structure of the second driving mechanism, in some embodiments of the first aspect of the present invention, the second driving mechanism includes a second driving wheel 125, a second driven wheel 126, a second synchronous belt 127 and a second motor 128, the second driving wheel 125 and the second driven wheel 126 are arranged on the base frame 100, the second synchronous belt 127 is sleeved on the second driving wheel 125 and the second driven wheel 126, the second motor 128 is arranged on the base frame 100, and the output shaft of the second motor 128 is connected to the second driving wheel 125, and the second plug-in 122 is connected to the second synchronous belt 127 and can move synchronously with the second synchronous belt 127. The second motor 128 drives the second driving wheel 125 to rotate forward or reverse, and then the second synchronous belt 127 can drive the second plug-in 122 to insert into the second folding groove 121 or disengage from the second folding groove 121, which is simple and convenient. It is conceivable that the second driving mechanism may also be a cylinder or a hydraulic cylinder, which can directly drive the second plug-in 122 to move into or out of the second folding groove 121.

[0034] Similarly, in order to simplify the structure of the first driving mechanism, the first driving mechanism includes a first driving wheel, a second driving wheel and a first synchronous belt (not shown in the figure), the first driving wheel and the first driven wheel are arranged on the base frame 100, the first synchronous belt is sleeved on the first driving wheel and the first driven wheel, and the base frame 100 is provided with a first motor 113, the output shaft of the first motor 113 is connected to the first driving wheel, and the first plug-in 112 is connected to the first synchronous belt and can move synchronously with the first synchronous belt. When the first motor 113 drives the first driving wheel to rotate forward or reverse, the first synchronous belt can drive the first plug-in 112 to insert into the first folding groove 111 or to disengage from the first folding groove 111, which is simple and convenient. It can be imagined that the first driving mechanism can also be replaced by a cylinder or a hydraulic cylinder, and it is also possible to drive the first plug-in 112 to move by a cylinder or a hydraulic cylinder, which can be determined according to actual needs.

[0035] Further, in order to simplify the structure of the third driving mechanism, in certain embodiments of the first aspect of the present invention, the third driving mechanism includes a third driving wheel 133, a third driven wheel 134, a third synchronous belt 135 and a third motor 136, the third driving wheel 133 and the third driven wheel 134 are arranged on the base frame 100, the third synchronous belt 135 is sleeved on the third driving wheel 133 and the third driven wheel 134, the output shaft of the third motor 136 is connected to the third driving wheel 133; the third plug-in 132 is connected to the third synchronous belt 135 and can move synchronously with the third synchronous belt 135. When the third motor 136 drives the third driving wheel 133 to rotate forward or reverse, the third synchronous belt 135 can drive the third plug-in 132 to move and insert into the third folding groove 131 or to disengage from the third folding groove 131, which is simple and convenient. It is conceivable that the third driving mechanism can also be replaced by a cylinder or a hydraulic cylinder, and it is also possible to drive the third plug-in 132 to move by a cylinder or a hydraulic cylinder, which can be determined according to actual needs.

In order to simplify the structure of the first clamping mechanism 114, specifically, the first clamping mechanism 114 is a cylinder, and the first pressing member is a piston rod of the cylinder, and the cylinder can drive the piston rod to pass through the first opening 115 and contact the facial mask paper located in the first folding groove 111, thereby preventing the facial mask paper from following the first plug-in 112 and pulling out of the first folding groove 111. It is conceivable that the first clamping mechanism 114 can also be replaced by a motor and a screw mechanism structure, and the same purpose can be achieved by driving the screw of the screw mechanism through the first opening 115 and contacting the mask paper located in the first folding groove 111 by the motor.

[0037] Reference Figure 1 and Figure 3 Similarly, in order to prevent the facial mask paper from falling out of the second folding groove 121 following the second plug-in 122, in certain embodiments of the first aspect of the present invention, a second clamping mechanism 129 is provided on one side of the second folding seat 120, and a second opening 1201 connecting the outside and the second folding groove 121 is opened at a position on the side wall of the second folding seat 120 corresponding to the second clamping mechanism 129, and the second clamping mechanism 129 is provided with a second clamping member that can pass through the second opening 1201 and be inserted into the second folding groove 121.
