Description

Technical Field

[0001] This utility model relates to the field of facial mask packaging technology, and in particular to a membrane storage mechanism, a membrane positioning device, and a facial mask packaging machine. Background Technology

[0002] In the facial mask manufacturing industry, a facial mask packaging machine is often used to grasp the mask sheet. After grasping the mask sheet, it is conveyed to a mask folding machine for folding and bagging. Therefore, the production efficiency and product quality of the mask folding and bagging machine are closely related to the front-end mask packaging machine that grasps the mask sheet. However, current mask packaging machines that grasp the mask sheet still have many defects. One defect is that because mask sheets are generally produced and stored in stacks, adjacent mask sheets tend to stick together and are difficult to separate. Therefore, the machine often grasps at least two mask sheets at a time, which can easily cause malfunctions during the folding and bagging process, or result in a single bag containing more than one mask sheet, thus reducing product quality and user experience. Another defect is that existing mask packaging machines often have inconsistent left and right positions when conveying the grasped mask sheet to the mask folding machine, resulting in uneven folding and again reducing product quality and user experience.

[0003] Therefore, there is an urgent need to provide a mask sheet storage mechanism, a mask sheet positioning device, and a mask packaging machine that can simultaneously improve product quality and user experience. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a mask sheet storage mechanism, comprising: a membrane compartment for storing a mask sheet with openings, the membrane compartment including a support plate, an inner positioning rod, and an inner paddle assembly; a membrane compartment fixing base plate, the inner positioning rod being fixed to the membrane compartment fixing base plate and inserted into the opening of the mask sheet, the membrane compartment fixing base plate supporting the support plate; the support plate having a through hole for the inner positioning rod to pass through, and an inner paddle assembly being provided at the top of the inner positioning rod, relatively away from the membrane compartment fixing base plate, the inner paddle assembly including an inner paddle, the inner paddle applying a first downward resistance to the outer periphery of the opening of the mask sheet located below it and stored in the membrane compartment.

[0005] Furthermore, the inner paddle assembly also includes an inner paddle mounting block and a rotating shaft. The rotating shaft is mounted on the inner positioning rod, and the inner paddle mounting block can rotate around the rotating shaft. The inner paddle is mounted on the inner paddle mounting block and extends relative to the inner positioning rod. The inner paddle mounting block is provided with a first contact surface and a second contact surface, and the inner positioning rod is provided with a first limiting surface and a second limiting surface. The inner paddle mounting block is eccentrically positioned relative to the rotating shaft. In its natural state, the second contact surface contacts the second limiting surface, and the inner paddle is in a basically horizontal state, thereby applying a first downward resistance to the mask cloth located below and stored in the film compartment. When the mask cloth is to be placed into the film compartment, the mask cloth will press down the free end of the inner paddle that extends relative to the inner positioning rod, thereby driving the inner paddle mounting block to rotate around the rotating shaft. When the inner paddle rotates to a basically vertical state, the first contact surface contacts the first limiting surface, thereby allowing the mask cloth to be placed into the film compartment without being obstructed by the inner paddle.

[0006] Furthermore, the membrane compartment also includes an outer positioning rod, an inner positioning rod, an outer positioning rod, a through hole, and an opening, all of which are set as a pair. A pair of openings are set at the position of the mask cloth corresponding to the human eye. An inner paddle assembly is set at the top of each inner positioning rod, and the plane where the inner paddle is located is set to be basically horizontal and basically vertical, with the angle between the plane and the horizontal plane and the vertical plane being less than or equal to 15°.

[0007] To achieve another objective of this utility model, a mask sheet positioning device is provided, comprising: any of the above-mentioned mask sheet storage mechanisms; a lifting pressure plate having a pressure plate through hole opposite to the mask compartment, wherein the mask sheet stored in the mask compartment is picked up through the corresponding pressure plate through hole; and an outer lever, the outer lever comprising a sheet fixing part and a sheet body part, wherein the sheet fixing part is fixed at the edge of the pressure plate through hole, the sheet body part extends radially along the pressure plate through hole to above the pressure plate through hole, and the free end of the sheet body part can elastically deform relative to the sheet fixing part to apply a second downward resistance to the outer periphery of the mask sheet.

[0008] Furthermore, the mask sheet positioning device also includes a mask sheet sensor and a mask compartment lifting mechanism. The mask sheet sensor is located above the lifting pressure plate and directly above the pressure plate through hole. The mask sheet sensor detects the mask sheet located at the pressure plate through hole. The mask compartment lifting mechanism drives the film support plate to rise and fall relative to the pressure plate through hole. When the mask compartment lifting mechanism drives the film support plate to rise to synchronously drive the mask sheet stored in the mask compartment to rise, the mask sheet sensor detects that the mask sheet has risen to the pressure plate through hole, and then the mask compartment lifting mechanism stops working.

[0009] Furthermore, the mask sheet positioning device also includes a positioning plate. The positioning plate is installed at the edge of the through hole of the pressure plate. The positioning plate includes a plate guide and a plate positioning part. The plate guide guides the upward movement of the mask sheet in the film chamber towards the through hole of the pressure plate under the action of the film chamber lifting mechanism. The plate positioning part positions the mask sheet that rises into the through hole of the pressure plate.

[0010] Furthermore, multiple positioning plates and multiple outer paddles are evenly distributed around the outer periphery of the pressure plate through hole. The mask cloth storage mechanism has a pair of inner positioning rods and a pair of outer positioning rods. The first plane passing through the two central axes of the pair of outer positioning rods passes through the symmetrical center line of the pressure plate through hole. The second plane passing through the two central axes of the pair of inner positioning rods is parallel to the first plane. At the same time, the third plane passing through the two symmetrical center lines of the first and second planes passes through the center of the pressure plate through hole.

[0011] Furthermore, the number of membrane compartments is 2N, arranged in two rows and N columns with aligned rows and columns. The pressure plate has N through holes. The mask fabric positioning device also includes a lifting mechanism for the lifting pressure plate and a rotary motor. The membrane compartment fixed base plate can support the film support plate of each membrane compartment. The lifting mechanism for the lifting pressure plate is used to drive the lifting pressure plate to rise and fall, and the rotary motor is used to drive the membrane compartment fixed base plate to rotate, so that each membrane compartment in one of the two rows of membrane compartments is aligned with each pressure plate through hole.

[0012] Furthermore, the lifting mechanism of the lifting plate is set as a lifting cylinder. When it is necessary to alternate between the two rows of film chambers, the lifting cylinder first drives the lifting plate to rise, providing space for the movement of each film chamber. The rotary motor then drives the film chamber fixed base plate to rotate 180 degrees. When the through holes of each pressure plate of the lifting plate that has risen above the film chamber are aligned with each film chamber in a row, the lifting cylinder drives the lifting plate to descend.

[0013] To achieve another objective of this utility model, a facial mask packaging machine is provided, including any of the above-mentioned facial mask cloth positioning devices.

[0014] The beneficial effects of the mask sheet storage mechanism, mask sheet positioning device, and mask packaging machine provided by this utility model are as follows:

[0015] The inner positioning rod is inserted into the membrane compartment for storing the mask sheets and passes through the openings of each mask sheet. The inner paddle of the inner paddle assembly applies a first downward resistance to the outer periphery of the opening of the mask sheet below the highest mask sheet being grasped in the membrane compartment, causing it to fall back into the membrane compartment. This ensures that the grasped single mask sheet is accurately separated from the other mask sheets below it. Therefore, it ensures that the mask folding machine will not malfunction when folding and bagging, or that there will be no more than two mask sheets in one mask bag after folding and bagging. This significantly improves both product quality and user experience. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

Unless otherwise specified, the various features in the embodiments and examples of this utility model can be combined with each other, all within the scope of protection of this utility model.

[0027] refer to Figures 1 to 5As an objective of this utility model, a mask sheet storage mechanism 1 is provided, which includes a membrane compartment 11 and a membrane compartment fixing base plate 12. The membrane compartment 11 is used to store a mask sheet 10 with an opening 101 and includes a membrane support plate 111, an inner positioning rod 112 and an inner paddle assembly 113. It is understood that the membrane compartment 11 initially stores multiple mask sheets 10 stacked in layers. The inner positioning rod 112 is fixed on the membrane compartment fixing base plate 12 and passes through the opening 101 of the mask sheet 10. The film storage fixed base plate 12 can support the film support plate 111. Specifically, when the maximum number of mask sheets 10 are supported on the film support plate 111, the film storage fixed base plate 12 supports the film support plate 111. As the number of mask sheets 10 decreases, in order to keep the mask sheets 10 located at the highest point in the film storage 11 in the grasped position, the film support plate 111 can be driven to rise relative to the film storage fixed base plate 12 by the film storage lifting mechanism 5 along the inner positioning rod 112 (which will be further explained below). Then the film storage fixed base plate 12 no longer supports the film support plate 111. The film support plate 111 is provided with a through hole 1111 for the inner positioning rod 112 to pass through. An inner paddle assembly 113 is provided at the top of the inner positioning rod 112, which is relatively far away from the film compartment fixing base plate 12. The inner paddle assembly 113 includes an inner paddle 1131, which can apply a first downward resistance to the outer periphery of the opening 101 of the mask cloth 10 located below and stored in the film compartment. Therefore, the mask sheet storage mechanism 1 provided by this utility model stores mask sheets 10 with openings 101 by setting a membrane compartment 11. The inner positioning rod 112 is inserted into the membrane compartment 11 and passes through the openings 101 of each mask sheet 10. The inner paddle 1131 of the inner paddle assembly 113 applies a first downward resistance to the outer periphery of the openings 101 of the mask sheet 10 below the highest mask sheet 10 in the membrane compartment 11, so as to ensure that the single mask sheet 10 to be grasped is accurately separated from the other mask sheets 10 below it. Thus, it ensures that the mask folding machine will not malfunction when folding and bagging, or that there will be no more than two mask sheets 10 in one mask bag after folding and bagging. This significantly improves both product quality and user experience. In addition, since the inner positioning rod 112 passes through each mask cloth 10, it can play a role in positioning each mask cloth 10 well. This avoids the drawback of inconsistent left and right positions of the mask cloth 10 when the grasped mask cloth 10 is transferred to the mask folding machine, so that the mask cloth 10 is folded neatly when folding, which also improves product quality and user experience.

[0028] Please refer to the reference. Figure 3 and Figure 5Specifically, the inner paddle assembly 113 further includes an inner paddle mounting block 1132 and a rotating shaft 1133. The rotating shaft 1133 is mounted on the inner positioning rod 112. The inner paddle mounting block 1132 can rotate around the rotating shaft 1133. The inner paddle 1131 is mounted on the inner paddle mounting block 1132 and extends relative to the inner positioning rod 112. The inner paddle mounting block 1132 is provided with a first contact surface 11321 and a second contact surface 11322. The inner positioning rod 112 is provided with a first limiting surface 1121 and a second limiting surface 1122. The inner paddle mounting block 1132 is eccentrically positioned relative to the rotating shaft 1133. Figure 3 As shown, in its natural state, the second contact surface 11322 contacts the second limiting surface 1122, and the inner paddle 1131 is in a basically horizontal state, thereby applying a first downward resistance to the mask cloth 10 located below and stored in the film compartment 11. When the mask cloth 10 is to be placed into the film compartment 11, the mask cloth 10 will press down the free end 11311 of the inner paddle 1131 relative to the inner positioning rod 112, thereby driving the inner paddle mounting block 1132 to rotate around the pivot 1133. Figure 5 As shown, when the inner paddle 1131 rotates to a substantially vertical position, the first contact surface 11321 contacts the first limiting surface 1121, allowing the mask sheet 10 to be placed into the membrane compartment 11 without obstruction by the inner paddle 1131. In this way, the rotation angle of the inner paddle mounting block 1132 around the pivot axis 1133 is limited by the first limiting surface 1121 and the second limiting surface 1122 on the inner positioning rod 112. This ensures that the free end 11311 of the biased inner paddle 1131 maintains the first downward resistance applied to separate the mask sheet 10 in its natural state, i.e., its normal working state, while also allowing the inner paddle 1131 to rotate and deviate to a substantially parallel, i.e., substantially perpendicular, state to the extending direction of the inner positioning rod 112, as long as the inner paddle 1131 does not obstruct the mask. The placement of the cloth 10 makes it convenient and quick to replenish multiple stacked mask cloths 10 into the membrane compartment 11 along the inner positioning rod 112. After all the mask cloths 10 in the membrane compartment 11 have been grabbed and new mask cloths 10 have been replenished, the inner lever 1131 only needs to be rotated in the opposite direction to be basically perpendicular to the extension direction of the inner positioning rod 112. As long as the inner lever 1131 can reliably apply the first downward resistance, the newly replenished mask cloths 10 can be grabbed one at a time under the action of the first downward resistance.

[0029] Please refer to the reference. Figure 1Preferably, the membrane compartment 11 further includes an outer positioning rod 114. The inner positioning rod 112, the outer positioning rod 114, the through hole 1111, and the opening 101 are all set as a pair. The pair of openings 101 are set at the position of the mask cloth 10 corresponding to the human eye. An inner paddle assembly 113 is set at the top of each inner positioning rod 112. The plane where the inner paddle 1131 is located is basically horizontal and basically vertical, and the angle between the plane and the horizontal plane and the vertical plane is less than or equal to 15°. The value of the angle can be determined according to actual needs as long as it can ensure that the inner paddle 1131 can normally apply the first downward resistance and can smoothly replenish the new mask cloth 10. The value of the angle is preferably less than or equal to 3°. In this way, not only are the inner positioning rods 112 more comprehensively positioned internally for each mask sheet 10, but the pair of inner levers 1131 simultaneously apply two first downward resistances, making the separation of the mask sheet 10 more reliable. Furthermore, the pair of outer positioning rods 114 clamps and positions the outer periphery of each mask sheet 10. In this invention, unless otherwise specified, the inner positioning rods 112, outer positioning rods 114, and inner lever assembly 113 are all used in pairs. Correspondingly, the through holes 1111 on the film support plate 111 and the openings 101 of the mask sheet 10 are also set as a pair. More specifically, the two inner positioning rods... Rod 112 and outer positioning rod 114 are respectively fixed on the film compartment fixing base plate 12. Two inner paddle assemblies 113 are respectively set at the top of the two inner positioning rods 112. The film support plate 111 is provided with two through holes 1111. The two inner positioning rods 112 pass through the two through holes 1111 respectively. The film support plate 111 is sleeved on the two inner positioning rods 112. The two openings 101 on the mask cloth 10 correspond to the pair of eyes of the person applying the mask. The two inner positioning rods 112 pass through the two openings 101 on the mask cloth 10 respectively to initially position the mask cloth 10 on the film support plate 111 in the film compartment 11 and store it.

[0030] refer to Figure 6 and Figure 7 As another objective of this utility model, a mask sheet positioning device is provided, which includes any of the above-mentioned mask sheet storage mechanisms 1, and has the beneficial technical effects brought by any of the above-mentioned mask sheet storage mechanisms 1, which will not be elaborated here, and will be referred to in conjunction with the reference. Figures 1 to 5The mask sheet positioning device also includes a lifting pressure plate 2 and an outer lever 3. The lifting pressure plate 2 is provided with a pressure plate through hole 21 opposite to the mask compartment 11. The mask sheet 10 stored in the mask compartment 11 is picked up through the corresponding pressure plate through hole 21. The outer lever 3 includes a sheet fixing part 31 and a sheet body part 32. The sheet fixing part 31 is fixed at the edge of the pressure plate through hole 21. The sheet body part 32 extends radially along the pressure plate through hole 21 to above the pressure plate through hole 21. The free end of the sheet body part 32 can elastically deform relative to the sheet fixing part 31 to apply a second downward pushing resistance to the outer periphery of the mask sheet 10. Therefore, the mask sheet positioning device provided by this utility model, by setting a lifting pressure plate 2 with a pressure plate through hole 21, can not only grab the mask sheet 10 from the film chamber 11 through the pressure plate through hole 21, but also use the outer paddle 3 arranged at the edge of the pressure plate through hole 21 to apply a second downward resistance to the outer periphery of the mask sheet 10 below the grabbed mask sheet 10, so as to ensure that the single mask sheet 10 to be grabbed is accurately separated from the other mask sheets 10 below it. In particular, the second downward resistance of the outer paddle 3 and the first downward resistance of the inner paddle 1131 work together on the mask sheet 10, so the separation effect is better. This further ensures that the mask folding machine will not malfunction when folding and bagging, or that there will be no more than two mask sheets 10 in one mask bag after folding and bagging. It also significantly improves product quality and user experience. In addition, since the outer paddle 3 also has a certain limiting effect near the outer periphery of each mask cloth 10, when the grasped mask cloth 10 is conveyed to the mask folding machine, it can avoid the drawback of inconsistent left and right positions of the mask cloth 10 to a certain extent, so that the mask cloth 10 is folded neatly when folding, thus helping to improve product quality and user experience.

[0031] Please refer to the reference. Figure 6Preferably, the mask sheet positioning device further includes a mask sheet sensor 4 and a mask compartment lifting mechanism 5. The mask compartment lifting mechanism 5 may include a motor with a lifting drive rod or a cylinder with a reciprocating piston rod. The mask sheet sensor 4 is located above the lifting pressure plate 2 and directly above the pressure plate through hole 21. The mask sheet sensor 4 detects the mask sheet 10 located at the pressure plate through hole 21. The mask compartment lifting mechanism 5 drives the film support plate 111 to rise and fall relative to the pressure plate through hole 21. When the mask compartment lifting mechanism 5 drives the film support plate 111 to rise to synchronously drive the mask sheet 10 stored in the mask compartment 11 to rise, the mask sheet sensor 4 detects that the mask sheet 10 has risen to the pressure plate through hole 21, and then the mask compartment lifting mechanism 5 stops working. In this way, by utilizing the cooperation of the membrane sheet sensor 4 and the membrane chamber lifting mechanism 5, the membrane sheet sensor 4 can promptly determine whether the mask sheet 10 in the membrane chamber 11 has been grasped, and drive the support plate 111 to rise in time to maintain the position of the mask sheet 10 at the top of the membrane chamber 11. The membrane sheet sensor 4 can also promptly determine whether all the mask sheets 10 in the membrane chamber 11 have been grasped, and drive the support plate 111 to descend to the membrane chamber fixed base plate 12 to support the support plate 111 so as to replenish as many new mask sheets 10 as possible into the membrane chamber 11.

[0032] Please refer to the reference. Figure 6 and Figure 7 Preferably, the mask sheet positioning device further includes a positioning piece 6. The positioning piece 6 is installed at the edge of the pressure plate through hole 21. The positioning piece 6 includes a piece guide part 61 and a piece positioning part 62. The piece guide part 61 guides the upward movement of the mask sheet 10 in the film chamber 11 towards the pressure plate through hole 21 under the action of the film chamber lifting mechanism 5. The piece guide part 61 can correct the position of the mask sheet 10 in the film chamber 11. The piece positioning part 62 positions the mask sheet 10 that has risen into the pressure plate through hole 21. In this way, the piece guide part 61 and the piece positioning part 62 of the positioning piece 6 can abut against the outer periphery of the mask sheet 10, thereby playing a good limiting role. This can better avoid the drawback of inconsistent left and right positions of the mask sheet 10, and keep the mask sheet 10 neatly folded when folded, thus helping to improve product quality and user experience.

[0033] Please refer to the reference. Figure 6Preferably, multiple positioning pieces 6 and multiple outer levers 3 are evenly distributed around the outer periphery of the pressure plate through hole 21. The mask fabric storage mechanism has a pair of inner positioning rods 112 and a pair of outer positioning rods 114. A first plane passing through the two central axes of the pair of outer positioning rods 114 passes through the symmetrical center line of the pressure plate through hole 21. A second plane passing through the two central axes of the pair of inner positioning rods 112 is parallel to the first plane. At the same time, a third plane passing through the two symmetrical center lines of the first and second planes passes through the center of the pressure plate through hole 21. Therefore, by using the evenly arranged multiple positioning pieces 6 and multiple outer levers 3, a more uniform peripheral limiting force and separation force can be provided to the mask fabric 10. Furthermore, the arrangement of the pair of outer positioning rods 114 and the pair of inner positioning rods 112 is also conducive to providing symmetrical outer and inner limiting forces and symmetrical first downward resistance in the middle part of the mask fabric 10, thereby obtaining a good limiting effect and separation effect.

[0034] Please refer to the reference. Figure 6 Preferably, the number of film compartments 11 is 2N, arranged in two rows and N columns with aligned rows and columns. The number of pressure plate through holes 21 is set to N. The mask fabric positioning device also includes a lifting pressure plate lifting mechanism 7 and a rotary motor 8. The film compartment fixing base plate 12 can support the film support plate 111 of each film compartment 11. The lifting pressure plate lifting mechanism 7 is used to drive the lifting pressure plate 2 to rise and fall, and the rotary motor 8 is used to drive the film compartment fixing base plate 12 to rotate, so that each film compartment 11 in one of the two rows of film compartments 11 is aligned with each pressure plate through hole 21. In this utility model, N is 3. The number of membrane compartments 11 is 6, arranged in two rows and three columns, that is, there are 3 inner membrane compartments 11 and 3 outer membrane compartments 11 relative to the lifting pressure plate 2. The 3 inner membrane compartments 11 are in working state, and the 3 outer membrane compartments 11 are used for manual replenishment of mask sheets 10. There are 3 through holes 21 on the pressure plate. When all the mask sheets 10 in the 3 inner membrane compartments 11 have been grasped, the rotary motor 8 works to drive the membrane compartment fixing base plate 12 to rotate, thus swapping the positions of the 3 inner membrane compartments 11 and the 3 outer membrane compartments 11. In this way, the mask sheet positioning device can start working again. Therefore, through the coordinated work of the lifting pressure plate lifting mechanism 7 and the rotary motor 8, the mask sheet positioning device can automatically switch the row of membrane compartments 11 that have replenished the mask sheets 10 to be aligned with each pressure plate through hole 21, thereby providing high-efficiency positioning and separation for grasping the mask sheets 10 in each membrane compartment 11.

[0035] Please refer to the reference. Figure 6Preferably, the lifting mechanism 7 of the lifting pressure plate is a lifting cylinder. In this embodiment, the lifting cylinders are a pair and arranged at both ends of the lifting pressure plate 2. When it is necessary to alternate between the two rows of film compartments 11, the lifting cylinder first drives the lifting pressure plate 2 to rise, providing space for the displacement of each film compartment 11. Then, the rotary motor 8 drives the film compartment fixing base plate 12 to rotate 180 degrees. When the pressure plate through holes 21 of the lifting pressure plate 2 above the film compartment 11 are aligned with each film compartment 11 in a row, the lifting cylinder drives the lifting pressure plate 2 to fall. Therefore, the lifting cylinder can accurately and reliably drive the lifting pressure plate 2 to rise and fall to avoid interference with the lifting pressure plate 2 when the two rows of film compartments 11 are interchanged, ensuring the reliable operation of the mask fabric positioning device.

[0036] The following further explains the operation when a new mask sheet 10 needs to be replenished and how the mask sheet 10 is grasped. First, the lifting cylinder 7 drives the lifting plate 2 to rise, making way for the mask compartment 11. Then, the rotary motor 8 starts and drives the fixed base plate 12 of the mask compartment to rotate 180 degrees. When the mask compartment 11 reaches below the lifting plate 2, and the through hole 21 of the pressure plate is aligned with the mask compartment 11, the lifting cylinder 7 drives the lifting plate 2 to descend, and the mask sheet 10 is grasped. The film storage lifting mechanism 5 drives the film support plate 111 in the film storage 11 to rise, and the mask cloth 10 stored in the film storage 11 also rises. When the mask cloth 10 in the film storage 11 is about to reach the pressure plate through hole 21, the guide portion 61 of the positioning piece 6 distributed around the pressure plate through hole 21 can guide the rising mask cloth 10 close to the pressure plate through hole 21, correcting the position of the mask cloth 10 in the film storage 11. The mask cloth 10 in the film storage 11 continues to rise under the drive of the film storage lifting mechanism 5. The mask continues to rise, and the positioning unit 62 precisely positions the mask cloth 10 that has reached the pressure plate through hole 21. When the mask cloth sensor 4 senses that the mask cloth 10 has reached the pressure plate through hole 21, the mask compartment lifting cylinder 5 stops working. At this time, the outer paddles 3, which are set on the lifting pressure plate 2 and distributed around the pressure plate through hole 21, will press down on the mask cloth 10, applying a downward resistance to the mask cloth 10. When the topmost mask cloth 10 is grabbed and lifted, the second mask cloth 10 below is also lifted by the first mask cloth. The mask sheet 10 is stuck together, but under the action of the second downward resistance applied by the outer paddle 3 and the first downward resistance of the inner paddle 1131, the second mask sheet 10 can overcome the adhesive force of the first mask sheet 10 and continue to remain in the mask compartment 11. Since the positioning plate 6 has precise positioning of the mask sheet 10 that reaches the pressure plate through hole 21, the position of the mask sheet 10 grasped each time is guaranteed and will not deviate to the left or right, thereby ensuring that the subsequent mask sheet 10 is neatly folded.
