Description

Technical Field

[0001] The utility model relates to the technical field of material counting and marking, in particular to a facial mask cloth folding machine with a reliable counting and marking function. Background Art

[0002] In many industries, it is necessary to count each time a certain quantity of material is reached, so that subsequent operations such as classification and packaging can be performed on the materials with the same specified quantity. This is especially true in the field of facial mask production for beauty care products. Some facial mask cloths need to be put into facial mask bags after being folded, while some facial mask cloths do not need to be put into facial mask bags after being folded. They only need to be neatly arranged and collected for subsequent repackaging. However, when repackaging is required, 20 or 30 pieces of folded facial mask cloths need to be put into a facial mask bag. However, the current facial mask cloth folding machine does not have a counting and marking function, and the folded mask cloths need to be counted manually before being put into the facial mask bags. This not only greatly wastes manpower, but also manual counting is prone to errors, resulting in inconsistent quantities of facial mask cloths being put into the facial mask bags, resulting in low counting reliability, which brings a poor experience to subsequent users.

[0003] Therefore, there is an urgent need to provide a facial mask cloth folding machine with high counting reliability and reliable counting marking function. Utility Model Content

[0004] In response to the deficiencies of the above-mentioned prior art and to achieve one purpose of the present invention, the present invention provides a facial mask cloth folding machine with a reliable counting and marking function, comprising: a film feeding belt for transporting the facial mask cloth; a folding assembly, arranged on the transport path of the facial mask cloth and used for folding the facial mask cloth multiple times to obtain a folded back mask cloth; a storage assembly, used for storing the folded back mask cloth; a counting and marking assembly, used for arranging a marking piece for every predetermined number of folded back mask cloths in the storage assembly, thereby separating the predetermined number of folded back mask cloths; a positioning support plate, arranged below the counting and marking assembly, used for positioning the marking piece falling from the counting and marking assembly.

[0005] Furthermore, the counting mark assembly includes: a plurality of mark plates serving as marking parts; a mark supporting slot for storing a plurality of mark plates and provided with a drop opening for a mark plate to fall; a mark supporting mechanism for applying or releasing support to the mark plate; and a lower mark mechanism, which pushes the mark plate released from the support by the mark supporting mechanism into the storage assembly through the drop opening whenever the folded rear membrane cloth in the storage assembly reaches a predetermined number.

[0006] Furthermore, the label supporting mechanism includes a label supporting cylinder and a label supporting plate. The label supporting plate applies or releases support to the marking plate correspondingly located above the drop port under the drive of the label supporting cylinder. The marking plate includes a plate groove provided at the lower part thereof and an upper edge of the plate groove corresponding to the plate groove. The label supporting plate is inserted into the plate groove and supports the upper edge of the plate groove to prevent the above-mentioned marking plate from falling or the label supporting plate exits the plate groove to release the support for the marking plate. The lowering mechanism includes a lowering cylinder and a lowering plate. The lowering plate pushes the marking plate that has been released from support toward the drop port under the drive of the lowering cylinder.

[0007] Furthermore, the facial mask cloth folding machine also includes a film cloth detector, and the folding component includes a first folding knife, a second folding knife and a third folding knife; the storage component includes a pushing block, a pair of horizontal inserting knives, a top film cylinder and a material trough, and the two horizontal inserting knives are close to each other to prevent the folded rear film cloth stored in the material trough from moving toward the pushing block, and there is a gap corresponding to the third folding knife between the pushing block and the horizontal inserting knife, and the gap is used to accommodate the third folding knife and the folded rear film cloth; the film feeding belt first transports the facial mask cloth to the bottom of the first folding knife, and after the film cloth detector detects the facial mask cloth, the first folding knife folds the facial mask cloth into the first folding forming groove, and the second folding knife folds the facial mask cloth into the second folding forming groove. The three-fold knife then folds the mask cloth to obtain a folded back film cloth, and the three-fold knife sends the folded back film cloth to the storage component through the three-fold forming groove. The film-pushing cylinder presses the folded back film cloth against the horizontal knife through the makeshift hole opened on the three-fold knife, and the three-fold knife returns to its original position. After the three-fold knife returns to its original position, the folded back film cloth is located in the gap, and the two horizontal knives move away from each other to make way, and the pushing block moves forward to push the folded back film cloth into the material trough, and the two horizontal knives move closer to each other. After the horizontal knife passes through the horizontal slot of the pushing block, the pushing block retreats to its original position, so that the folded back film cloth is stored in the material trough under the obstruction of the horizontal knife.

[0008] Furthermore, the facial mask cloth folding machine also includes a positioning support cylinder, the free end of the piston rod of the positioning support cylinder is fixedly connected to the positioning support plate, when the lower mark cylinder drives the lower mark plate to push down the released marking plate, the marking plate falls through the drop port to the gap between the pushing block and the horizontal inserting knife corresponding to the three-fold knife, the positioning support cylinder drives the positioning support plate through the pushing block through the hole on the pushing block to the bottom of the drop port and then supports the upper edge of the plate groove of the falling marking plate, so that the positioning support plate prevents the marking plate from falling onto the storage assembly.

[0009] Furthermore, a positioning support plate is provided on the pushing block, and the positioning support plate extends to the bottom of the drop port. When the marking plate falls through the drop port into the gap between the pushing block and the horizontal inserting knife corresponding to the tri-fold knife, the positioning support plate supports the upper edge of the plate groove of the falling marking plate, thereby preventing the marking plate from falling onto the storage assembly.

[0010] Furthermore, the plate groove is arranged through the lower part of the marking plate, and the center of gravity of the marking plate is located below the upper edge of the plate groove. When the positioning support plate supports the upper edge of the plate groove, the marking plate remains vertical under the action of gravity, so that the pushing block can smoothly push the marking plate into the material groove.

[0011] Furthermore, the counting mark assembly also includes a mark plate detection mechanism, which is used to detect whether there is a mark plate in the mark supporting slot. The mark plate detection mechanism includes a mark plate sensor and a paddle. The paddle includes a trigger part and a force-bearing part. When the mark plate is located above the drop port and abuts against the force-bearing part, the force-bearing part is acted upon by the mark plate and moves so that the trigger part triggers the mark plate sensor, thereby detecting the presence of a mark plate at the drop port. When the force-bearing part is not acted upon by the mark plate, the trigger part does not trigger the mark plate sensor, thereby detecting the absence of a mark plate at the drop port. The counting mark assembly includes a support plate, and the mark supporting mechanism and the lower mark mechanism are arranged on the support plate. Two openings are provided on the support plate for respectively allowing the supporting mark plate and the lower mark plate to pass through. The mark plate sensor is fixed on the support plate. The mark plate sensor includes a transmitting end and a receiving end with a gap between the two. The paddle is pivotally supported on the support plate. The trigger part and the force-bearing part are arranged at the opposite ends of the paddle. A slot is provided on the support plate for the force-bearing part to move therein. Under the action of the mark plate, the force-bearing part rotates away from the slot to drive the trigger part into the gap, thereby preventing the signal transmission and reception between the transmitting end and the receiving end. The force-bearing part rotates into the slot when it does not receive the action of the mark plate to drive the trigger part away from the gap, thereby allowing the signal transmission and reception between the transmitting end and the receiving end.

[0012] Furthermore, the facial mask cloth folding machine also includes an upper baffle, which is fixed on the support plate and arranged above the marking plate in the marking groove. When the lower marking cylinder drives the lower marking plate to push down the released marking plate and then retracts, the upper baffle is used to prevent the marking plate from being driven upward by the retracted lower marking plate.

[0013] Furthermore, the counting mark assembly also includes a pressing plate, which is used to press each marking plate toward the drop port. When the folded rear film cloth in the material trough reaches a predetermined number and the marking plate detection mechanism detects that there is a marking plate above the drop port below the marking support trough, the marking support cylinder drives the marking support plate to retract to release the marking plate, and the lower marking cylinder drives the lower marking plate to push down the released marking plate, and the marking plate falls into the gap through the drop port. The paired horizontal inserts then move away from each other to form a space for the pushing block to move forward, and the pushing block pushes the marking plate into the material trough. After a predetermined number of folded rear membrane cloths are received, another marking plate is similarly pushed into the material trough by the pushing block, and so on; the label supporting trough is inclined relative to the horizontal direction, and the marking plate moves to the top of the drop port under the action of its own gravity and the pressure of the pressure plate and can be supported by the label supporting mechanism. The lower label mechanism also includes a guide plate provided above the pushing block, so that the marking plate can be aligned and dropped into the gap. The material trough includes two oppositely arranged material trough guard plates, and the storage assembly also includes a material trough width adjustment handwheel for adjusting the distance between the two material trough guard plates to adapt to the width of the folded rear membrane cloth.

[0014] The mask cloth folding machine with reliable counting and marking function provided by the utility model has the following beneficial effects:

[0015] By setting up a counting mark component, a marking piece can be automatically arranged in the storage component after each predetermined number of folded back film cloths are stored in the storage component, so that there is a predetermined number of folded back film cloths between every two adjacent marking pieces. Therefore, the folded back film cloths can be counted and marked automatically and accurately. Moreover, the provided positioning support can effectively prevent the marking piece from being skewed when falling into the storage component, thereby ensuring that the facial mask cloth folding machine will not work abnormally due to the skewness of the marking piece, thereby achieving the purpose of counting the folded back film cloth with high reliability.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element limited by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element. If there is no conflict, the various features of the embodiments and examples of the present invention may be combined with each other and are all within the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 6As an object of the present invention, a facial mask cloth folding machine with a reliable counting mark function is provided, which includes a film feeding belt 1, a folding component 2, a storage component 3, a counting mark component 4 and a positioning tray 5. The film feeding belt 1 is used to transport the facial mask cloth 10. The folding component 2 is arranged on the transportation path of the facial mask cloth 10, and is used to fold the facial mask cloth 10 multiple times to obtain a folded back mask cloth 10'. Specifically, during the multiple folding processes of the folding component 2, the facial mask cloth is shifted to multiple corresponding folding positions. The storage component 3 is used to store the folded back mask cloth 10' obtained by multiple foldings of the folding component 2. The counting mark component 4 is used to arrange a marking member for every predetermined number of folded back mask cloths 10' in the storage component 3, thereby separating the predetermined number of folded back mask cloths 10'. The positioning tray 5 is arranged below the counting mark component 4, and is used to position the marking member falling from the counting mark component 4. Therefore, the mask cloth folding machine with a reliable counting marking function provided by the present invention can automatically arrange a marking piece in the storage component 3 after each predetermined number of folded rear mask cloths 10' are stored in the storage component 3 by setting a counting marking component 4, so that there is a predetermined number of folded rear mask cloths 10' between every two adjacent marking pieces. Moreover, if a positioning support plate 5 is not provided, the marking piece will bounce when it falls into the storage component 3, which may cause the marking piece to fall out of the storage component 5. The phenomenon of skewness occurs, resulting in the pushing block 31 being unable to smoothly push the marking piece into the material trough 34. Therefore, since the facial mask cloth folding machine with reliable counting and marking function of the present invention is provided with a positioning support plate 5, it can effectively prevent the marking piece from being skewed when falling into the storage component 5, thereby ensuring that the pushing block 31 can smoothly push the marking piece into the material trough 34. Therefore, a technical effect of high reliability in counting the folded rear membrane cloth 10' is achieved, thereby facilitating subsequent operations such as packaging of an accurate number of folded rear membrane cloths 10'.

[0027] Please refer to Figure 1 、 Figure 5 and Figure 6Specifically, the counting mark assembly 4 includes a plurality of mark plates 41, a mark supporting groove 42, a mark supporting mechanism 44 and a mark lowering mechanism 46. The mark plate 41 serves as the above-mentioned marking member. The mark supporting groove 42 is used to store a plurality of mark plates 41 and is provided with a drop opening 421 for a mark plate 41 to drop down. The mark supporting mechanism 44 is used to apply or release support to the mark plate 41. Whenever the number of folded rear film cloths 10' in the storage assembly 3 reaches a predetermined number, the mark lowering mechanism 46 pushes the mark plate 41 released from the support by the mark supporting mechanism 44 down into the storage assembly 3 through the drop opening 421. Therefore, the label-holding mechanism 44 and the label-dropping mechanism 46 can be programmed to work in coordination with each other. Only when the number of folded rear membrane cloths 10' stored in the storage component 3 reaches a predetermined number, the label-holding mechanism 44 will release the support for the marking plate 41, and the label-dropping mechanism 46 will then push the marking plate 41 down into the storage component 3, so that a marking plate 41 follows the predetermined number of folded rear membrane cloths 10', and the user can easily identify the number of folded rear membrane cloths 10' between each marking plate 41.

[0028] Please refer to Figure 5 and Figure 6 Specifically, the label supporting mechanism 44 includes a label supporting cylinder 441 and a label supporting plate 442. The label supporting plate 442 applies or releases support to the marking plate 41 correspondingly located above the drop port 421 under the drive of the label supporting cylinder 441. The marking plate 41 includes a plate groove 411 and an upper edge 412 of the plate groove corresponding to the plate groove 411. The label supporting plate 442 is inserted into the plate groove 411 and supports the upper edge 412 of the plate groove to prevent the above-mentioned marking plate 41 from falling or the label supporting plate 442 withdraws from the plate groove 411 to release the support for the marking plate 41. The lower label mechanism 46 includes a lower label cylinder 461 and a lower label plate 462. The lower label plate 462 pushes the marking plate 41, which has been released from support, downward toward the drop port 421 under the drive of the lower label cylinder 461. In this case, the support and push-down of the marking plate 41 are respectively driven by the support cylinder 441 and the lower mark cylinder 461, which has high reliability and stability.

[0029] Please refer to Figure 1 and Figure 4Specifically, the facial mask folding machine further includes a mask detector 8; the folding assembly 2 includes a first folding knife 21, a second folding knife 22, and a third folding knife 23. The storage assembly 3 includes a pusher block 31, a pair of horizontal inserting knives 32, a film-lifting cylinder 33, and a material trough 34. The two horizontal inserting knives 32 are positioned close together to prevent the folded rear face mask 10' stored in the material trough 34 from moving toward the pusher block 31. A gap corresponding to the third folding knife 23 is defined between the pusher block 31 and the horizontal inserting knives 32 to accommodate the third folding knife 23 and the folded rear face mask 10'. The film feeding belt 1 first transports the mask cloth to the bottom of the first folding knife 21. After the film cloth detector 8 detects the mask cloth, the first folding knife 21 folds the mask cloth into the first fold forming groove, the second folding knife 22 folds the mask cloth into the second fold forming groove, and the third folding knife 23 folds the mask cloth to obtain the folded back film cloth 10'. The third folding knife 23 sends the folded back film cloth 10' to the storage component 3 through the third fold forming groove, and the top film cylinder 33 presses the folded back film cloth 10' onto the horizontal inserting knife 32 through the give way hole opened on the third folding knife 23, and the third folding knife 23 returns to its original position. After the three-fold knife 23 returns to its original position, the folded back membrane cloth 10' is located in the gap, the two horizontal inserting knives 32 move away from each other to make way, and the pushing block 31 moves forward to push the folded back membrane cloth 10' into the material trough 34. The two horizontal inserting knives 32 then move closer to each other. After the horizontal inserting knife 32 passes through the horizontal slot hole of the pushing block 31, for example, in the middle part, the pushing block 31 retreats to its original position, so that the folded back membrane cloth 10' is stored in the material trough 34 under the obstruction of the horizontal inserting knife 32, which can prevent the folded back membrane cloth 10' in the material trough 34 from moving toward the pushing block 31. Therefore, the folding assembly 2 not only has a high degree of automation for the folding operation of the facial mask cloth, but also ensures that each folded back membrane cloth 10' is sent to a position in the material trough 34 that does not interfere with the falling position of the marking plate 41.

[0030] Please refer to Figure 1 and Figure 2 As a specific setting method of the positioning support plate, the facial mask cloth folding machine also includes a positioning support plate cylinder 6, the free end of the piston rod of the positioning support plate cylinder 6 is fixedly connected to the positioning support plate 5, when the lower marking cylinder 461 drives the lower marking plate 462 to push down the released marking plate 41, the marking plate 41 falls through the drop opening 421 to the gap between the pushing block 31 and the horizontal inserting knife 32 corresponding to the three-fold knife 23, the positioning support plate cylinder 6 drives the positioning support plate 5 through the pushing block through the hole 311 on the pushing block 31 to the bottom of the drop opening 421 and then supports the upper edge 412 of the plate groove of the marking plate 41, so that the positioning support plate 5 prevents the marking plate from falling onto the storage component 3. In this way, by setting the positioning support plate 5 to be movably connected to the positioning support plate cylinder 6, the positioning support plate 5 can be accurately driven and relatively independently moved to support the upper edge 412 of the plate groove of the marking plate 41, thereby reliably preventing the marking plate 41 from tilting when falling into the storage component 5.

[0031] As another specific arrangement of the positioning support plate, the positioning support plate 5 is arranged on the pusher block 31 (not shown), and the positioning support plate 5 extends below the drop opening 421. When the marking plate 41 falls through the drop opening 421 into the gap between the pusher block 31 and the horizontal inserting knife 32 corresponding to the three-fold knife 23, the positioning support plate 5 supports the upper edge 412 of the plate groove of the falling marking plate 41, thereby preventing the marking plate 41 from falling onto the storage assembly 5. In this way, by arranging the positioning support plate 5 to be directly fixedly connected to the pusher block 31 and moving with the pusher block 31, it is possible to save costs while also reliably preventing the marking plate 41 from tilting when falling into the storage assembly 5.

[0032] Please refer to Figure 5 Specifically, the plate groove 411 is provided through the lower part of the marking plate 41, and the center of gravity of the marking plate 41 is located below the upper edge 412 of the plate groove. When the positioning support plate 5 supports the upper edge 412 of the plate groove, the marking plate 5 remains in a vertical state under the action of gravity, so that the pushing block 31 can smoothly push the marking plate 41 into the material trough 34. In this way, by providing the plate groove 411 as a through-groove structure located at the lower part of the marking plate 41, the positioning support plate 5 can first wait for the marking plate to fall below the drop opening 421. Then, during the falling process of the marking plate 41, the positioning support plate 5 passes through the plate groove 411 to position and support the upper edge 412 of the plate groove of the marking plate 41, thereby ensuring that each marking plate 41 can be reliably positioned and supported.

[0033] Please refer to Figure 5 and Figure 6 Specifically, the counting mark assembly 4 also includes a mark plate detection mechanism 45, which is used to detect whether the mark plate 41 is present in the mark supporting slot 42. The mark plate detection mechanism 45 includes a mark plate sensor 451 and a paddle 452. The paddle 452 includes a trigger portion 4521 and a force-bearing portion 4522. When the mark plate 41 is located above the drop opening 421 and abuts against the force-bearing portion 4522, the force-bearing portion 4522 is acted upon by the mark plate 41 and moves so that the trigger portion 4521 triggers the mark plate sensor 451, thereby detecting the presence of the mark plate 41 at the drop opening 421. When the force-bearing portion 4522 is not acted upon by the mark plate 41, the trigger portion 4521 does not trigger the mark plate sensor 451, thereby detecting the absence of the mark plate 41 at the drop opening 421. In this way, it is possible to detect in real time whether there is a marking plate 41 at the drop port 421, which is convenient for the user to replenish the marking plate 41 in the label holding slot 42 in time, and prevent the marking plate 41 from failing to fall in time after the folded rear membrane cloth 10' in the storage component 3 reaches the predetermined number for marking and separation, thereby ensuring accurate counting of the predetermined number.

[0034] The counting mark assembly 4 includes a support plate 47, a support mark mechanism 44 and a lower mark mechanism 46 are arranged on the support plate 47, and two openings 471 are provided on the support plate 47 to allow the support mark plate 442 and the lower mark plate 462 to pass through respectively. The mark plate sensor 451 is fixed on the support plate 47. For example, the mark plate sensor 451 using an infrared sensor includes a transmitting end and a receiving end with a gap between the two. The paddle 452 is pivotally supported on the support plate 47, and the trigger part 4521 and the force-bearing part 4522 are arranged on the support plate 47. At opposite ends of the paddle 452, the support plate 47 is provided with slots 472 for the force-bearing portion 4522 to move therein. Under the action of the marking plate 41, the force-bearing portion 4522 rotates away from the slots 472 to drive the trigger portion 4521 into the gap, thereby preventing signal transmission between the transmitting end and the receiving end. When the force-bearing portion 4522 does not receive the action of the marking plate 41, it rotates into the slots 472 to drive the trigger portion 4521 away from the gap, thereby allowing signal transmission between the transmitting end and the receiving end. Therefore, through the arrangement of this preferred embodiment, not only is the overall structure of the counting mark assembly 4 compact and the various components reliable, but the force-bearing portion 4522 of the paddle 452 can sensitively and synchronously drive the trigger portion 4521 to move relative to each other in the gap according to the presence or absence of force from the marking plate 41, thereby ensuring that the marking plate sensor 451 can accurately and reliably determine the presence or absence of the marking plate 41 in the trough 34.

[0035] Please refer to Figure 4 and Figure 6 Preferably, the mask cloth folding machine further comprises an upper baffle 7, which is fixed on the support plate 47 and arranged above the marking plate 41 in the marking groove 42. When the lower marking cylinder 461 drives the lower marking plate 462 to push down the released marking plate 41 and then retracts, the upper baffle 7 is used to prevent the marking plate 41 from being driven upward by the retracted lower marking plate 462. In this way, when the lower marking cylinder 461 drives the lower marking plate 462 to push down the released marking plate 41 and then retracts, it is easy to drive the marking plate 41 in the marking groove 42 that is in contact with the lower marking plate 462 to move upward, resulting in an abnormal operation such as the lower marking plate 462 being unable to be driven normally or / and the remaining marking plates 41 being unable to move normally toward the drop port 421. Therefore, by arranging an upper baffle 7 on the mask cloth folding machine, it is possible to prevent the marking plate 41 from being driven upward by the retracted lower marking plate 462, thereby ensuring normal operation.

[0036] Please refer to Figure 1 、 Figure 5 and Figure 6Preferably, the counting mark assembly 4 further includes a pressing plate 43, which is used to press each mark plate 41 toward the drop port 421. The pressing plate 43 can prevent the mark plates 41 in the mark supporting groove 42 from falling over. When the folded rear membrane cloth 10' in the material trough 34 reaches a predetermined number and the marking plate detection mechanism 45 detects that there is a marking plate 41 above the drop port 421 below the label supporting trough 42, the label supporting cylinder 441 drives the label supporting plate 442 to retract, thereby releasing the marking plate 41, and the lower label cylinder 461 drives the lower label plate 462 to push down the released marking plate 41, and the marking plate 41 falls into the gap through the drop port 421. The paired horizontal knives 32 then move away from each other to form a space for the pushing block 31 to move forward, and the pushing block 31 pushes the marking plate 41 into the material trough 34. After the material trough 34 has received a predetermined number of folded rear membrane cloths 10', another marking plate 41 is similarly pushed into the material trough 34 by the pushing block 31, and so on. Therefore, the mask cloth folding machine has a high degree of automation and high counting accuracy. By utilizing the above-mentioned gap and the relative movement of the paired transverse knives 32, it can ensure that the mask cloth 10' and the marking plate 41 are reliably fed into the material trough 34 after folding and will not fall out of the material trough 34.

[0037] The label holding trough 42 is tilted relative to the horizontal direction. The marking plate 41 moves to the top of the drop port 421 under the action of its own weight and the pressure of the pressure plate 43 and can be supported by the label holding mechanism 44, preventing the marking plate 41 from not being able to fill the vacant space left by the fallen marking plate 41 in time. The lower label mechanism 46 also includes a guide plate 463 provided above the pushing block 31, so that the marking plate 41 falls into the gap in an aligned manner, so that the marking plate 41 does not move left and right when falling into the gap. The trough 34 includes two trough guard plates arranged opposite to each other, and the storage assembly 3 also includes a trough width adjustment hand wheel 37 for adjusting the distance between the two trough guard plates, so as to adapt to the width of the membrane cloth 10' after folding, so that the membrane cloth 10' after folding can be smoothly stored in the trough 34.

[0038] Preferably, the mask cloth folding machine further includes a controller (not shown) and a folded mask cloth counter electrically connected to the mask cloth detector 8. The folded mask cloth counter counts the number of mask cloths detected by the mask cloth detector 8. The controller is electrically connected to the mask cloth detector 8 and controls the operation of the label support mechanism 44 and the label lowering mechanism 46 according to the counting result of whether the count reaches a predetermined number. In this way, it is possible to accurately determine whether the folded mask cloth 10' has reached the predetermined number, thereby automatically realizing the control of the drop of the marking plate 41.

[0039] Please refer to Figure 4Preferably, the storage assembly 3 further includes a stopper 35 and a trough membrane cloth sensor 36 respectively provided inside and at the rear end of the trough 34. The stopper 35 can prevent the folded rear membrane cloth 10' in the trough 34 from falling over, thereby ensuring that the folded rear membrane cloth 10' stored in the trough 34 is aligned and arranged in sequence in an upright manner, which not only facilitates the subsequent one-time removal of each predetermined number of folded rear membrane cloths 10', but also ensures the reliable positioning of the marking plate 41 in the trough 34. When the folded rear membrane cloth 10' in the trough 34 is full, the stopper 35 approaches the trough membrane cloth sensor 36 under the action of the folded rear membrane cloth 10', and the trough membrane cloth sensor 36 generates a sensing signal to determine that the folded rear membrane cloth 10' in the trough 34 is full, and generates an alarm signal to prompt the machine to stop and wait for the folded rear membrane cloth 10' that has been counted and marked according to the predetermined number to be removed. In this way, when the folded rear membrane cloth 10' is fully stored in the material trough 34, the machine can be stopped and the folded rear membrane cloth 10' can be removed in time to prevent the folded rear membrane cloth 10' or the marking plate 41 from being unable to be pushed into the material trough 34, resulting in material piling up in the gap, interference and damage to components, and other adverse situations.

[0040] The above provides a mask cloth folding machine with a reliable counting mark function, but the counting mark component 4 can also be changed in various forms. For example, the mark plate detection mechanism 45 in the counting mark component 4 can also detect whether there is a mark plate 41 pushed down into the storage component 3 during the process of the lower mark mechanism 46 pushing down the mark plate 41. If not detected, an alarm can be issued to stop the machine; for example, the mark plate 41 can be set to be heavy enough, so that the lower mark mechanism 46 in the counting mark component 4 can be omitted, because when the support mechanism 44 releases the support for the mark plate 41, the mark plate 41 can be free due to its own gravity. The marking plate 41 is supported by the support plate 42 and the support plate 421 is supported by the support plate 422. The support plate 41 is supported by the support plate 42 and the support plate 422 is supported by the support plate 42. When the marking plate 462 pushes the marking plate 41 down into the storage component 3, the distance between the lower end surface of the lower marking plate 462 and the positioning support plate 5 is exactly equal to the distance between the upper edge 412 of the plate groove and the top surface of the marking plate 41. In this way, the marking plate 41 is completely confined between the lower end surface of the lower marking plate 462 and the positioning support plate 5 without any bouncing or tilting, which is very conducive to the pushing block 31 pushing the marking plate 41 into the material trough 34. For example, the counting marking component 4 can not only be set above the storage component 3, but also be set on the side of the storage component 3, and on both sides of the storage component 3 relative to the folding component 2. At this time The drop-off opening 421 of the label holding slot 42 in the counting mark component 4 is no longer at the bottom of the label holding slot 42, but on both sides of the end of the label holding slot 42. At this time, there is no label holding mechanism 44 in the counting mark component 4, and the marking plate 41 can be directly stored in the label holding slot 42. When the folded rear membrane cloth 10' in the storage component 3 reaches a predetermined number, the lower marking mechanism 46 is configured to move telescopically facing the two sides of the end of the label holding slot 42, so that the marking plate 41 in the label holding slot 42 can be directly pushed horizontally into the storage component 3 through the drop-off opening 421, thereby achieving the same technical effect of marking the folded rear membrane cloth 10' in the storage component 3.
