Description

Technical Field

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

[0002] In many industries, it is necessary to count each time a certain quantity of materials is reached, so as to perform subsequent operations such as classification and packaging on the materials with the same specified quantity. Especially in the field of facial mask production of 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 facial mask cloths need to be counted manually before being put into the facial mask bag. 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 bag, which brings a poor experience to subsequent users.

[0003] Therefore, there is an urgent need to provide a facial mask cloth folding machine with a counting and marking function that can automatically count and mark with high counting accuracy. Utility Model Content

[0004] In view of the deficiencies of the above-mentioned prior art and to achieve one purpose of the utility model, a facial mask cloth folding machine with a counting and marking function is provided, comprising: a film feeding belt for conveying the facial mask cloth; a folding assembly, which is arranged on the conveying path of the facial mask cloth and is used to fold the facial mask cloth multiple times to obtain a folded rear film cloth; a storage assembly, which is used to store the folded rear film cloth; and a counting and marking assembly, which is used to arrange a marking piece for every predetermined number of folded rear film cloths in the storage assembly, so as to separate the predetermined number of folded rear film cloths.

[0005] Furthermore, the counting mark assembly includes: a plurality of mark plates serving as marking members; a mark supporting slot for storing a plurality of mark plates and having a drop opening for a mark plate to fall into; a pressure plate for pressing each mark plate toward the drop opening; a mark supporting mechanism for applying or releasing support to the mark plate; a mark plate detection mechanism for detecting whether there is a mark plate in the mark supporting slot; 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. When driven by the label supporting cylinder, the label supporting plate applies or releases support to the marking plate correspondingly located above the drop port. The marking plate includes an opening and an upper edge of the opening corresponding to the opening. The label supporting plate is inserted into the opening and supports the upper edge of the opening to prevent the above-mentioned marking plate from falling or the label supporting plate withdraws from the opening to release the support for the marking plate. The lowering mechanism includes a lowering cylinder and a lowering plate. When driven by the lowering cylinder, the lowering plate pushes the marking plate, which has been released from support, downward toward the drop port.

[0007] Furthermore, the mark plate detection mechanism includes a mark plate sensor and a paddle, and 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 the 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 that no mark plate is present at the drop port.

[0008] Furthermore, the counting mark assembly includes a support plate, a mark supporting mechanism and a mark lowering mechanism are arranged on the support plate, two openings are provided on the support plate for respectively allowing the mark supporting plate and the mark lowering 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 opposite ends of the paddle, and 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 without receiving 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.

[0009] Furthermore, the mask cloth folding machine also includes a mask cloth detector, the folding component includes a 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, the two horizontal inserting knives are close to each other to prevent the folded rear mask 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, the gap is used to accommodate the third folding knife and the folded rear mask cloth; the film feeding belt first transports the mask cloth to the bottom of the first folding knife, and after the mask cloth detector detects the mask cloth, the first folding knife folds the mask cloth into the first folding forming groove, and the second folding knife folds the mask cloth into the second folding forming groove. The three-fold knife then folds the mask cloth to obtain a folded back membrane cloth, and the three-fold knife sends the folded back membrane cloth to the storage component through the three-fold forming groove, and the film-pushing cylinder presses the folded back membrane cloth against the horizontal insert knife through the make way 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 membrane cloth is located in the gap, and the two horizontal insert knives move away from each other to make way, and the pushing block moves forward to push the folded back membrane cloth into the material trough, and the two horizontal insert knives move closer to each other, and after the horizontal insert knife passes through the horizontal slot hole of the pushing block, the pushing block retreats to its original position, so that the folded back membrane cloth is stored in the material trough under the obstruction of the horizontal insert knife.

[0010] Furthermore, when the folded rear membrane 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 opening below the label supporting trough, the label supporting cylinder drives the label supporting plate to retract to release the marking plate, and the lower label cylinder drives the lower label plate to push down the released marking plate, and the marking plate falls into the gap through the drop opening. The paired horizontal knives 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 the material trough has received a predetermined number of folded rear membrane cloths, another marking plate is similarly pushed into the material trough by the pushing block, and so on.

[0011] Furthermore, the label supporting trough is inclined relative to the horizontal direction. The marking plate moves to the top of the drop port under the action of its own gravity and the resistance pressure of the pressure plate and can be supported by the label supporting mechanism. The label lowering mechanism also includes a guide plate arranged above the pushing block, so that the marking plate can fall into the gap in an aligned manner. The material trough includes two relatively arranged material trough guard plates, and the storage assembly also includes a material trough width adjustment hand wheel for adjusting the distance between the two material trough guard plates, so as to adapt to the width of the membrane cloth after folding.

[0012] Furthermore, the facial mask cloth folding machine also includes a controller and a folded film cloth counter electrically connected to the film cloth detector. The folded film cloth counter counts the number of facial mask cloths detected by the film cloth detector. The controller is electrically connected to the film cloth detector and controls the operation of the label supporting mechanism, the marking plate detection mechanism and the label placing mechanism accordingly according to whether the counting result reaches a predetermined number.

[0013] Furthermore, the storage component includes a block and a trough membrane cloth sensor which are respectively arranged inside and at the rear end of the material trough. The block can prevent the folded rear membrane cloth in the material trough from tipping over. When the folded rear membrane cloth in the material trough is full, the block approaches the trough membrane cloth sensor under the action of the folded rear membrane cloth. The trough membrane cloth sensor generates a sensing signal to determine that the folded rear membrane cloth in the material trough is full and generates an alarm signal to prompt the machine to stop and wait for the folded rear membrane cloth that has been counted and marked according to a predetermined quantity to be taken away.

[0014] The mask cloth folding machine with 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 a predetermined number of folded rear film cloths are stored in the storage component, so that there is a predetermined number of folded rear film cloths between every two adjacent marking pieces. Therefore, the advantages of automated counting marking, high counting accuracy, and convenience for subsequent packaging of an accurate number of folded rear film cloths can be obtained.

In the absence of further restrictions, the elements limited by the sentence "comprises..." do not exclude the presence of other identical elements in the process, method, article or device including the elements. If there is no conflict, the various features in the embodiments and embodiments of the utility model can be combined with each other, all within the scope of protection of the utility model.

[0025] Please refer to Figures 1 to 5As an object of the utility model, a facial mask cloth folding machine with a counting mark function is provided, which includes a film feeding belt 1, a folding component 2, a storage component 3 and a counting mark component 4. The film feeding belt 1 is used to transport the facial mask cloth 10. The folding component 2 is arranged on the transport path of the facial mask cloth 10, and is used to fold the facial mask cloth 10 multiple times to obtain a folded rear film 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 rear film cloth 10' obtained by multiple foldings of the folding component 2. The counting mark component 4 is used to arrange a marking piece every predetermined number of folded rear film cloths 10' in the storage component 3, thereby separating the predetermined number of folded rear film cloths 10'. Therefore, the facial mask cloth folding machine with counting and marking function provided by the utility model can automatically arrange a marking piece in the storage component 3 after storing a predetermined number of folded rear film cloths 10' in the storage component 3 by setting a counting and marking component 4, so that there is a predetermined number of folded rear film cloths 10' between every two adjacent marking pieces. Therefore, it has the advantages of automatic counting and marking and high counting accuracy, thereby facilitating subsequent packaging and other operations of an accurate number of folded rear film cloths 10'.

[0026] Please refer to Figure 1 , Figure 4 and Figure 5 Specifically, the counting mark assembly 4 includes a plurality of mark plates 41, a mark supporting groove 42, a pressure plate 43, a mark supporting mechanism 44, a mark plate detection mechanism 45 and a lower mark 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 fall. The pressure plate 43 is used to press each mark plate 41 toward the drop opening 421, and the pressure plate 43 can prevent the mark plates 41 in the mark supporting groove 42 from tipping over. The mark supporting mechanism 44 is used to apply or release support to the mark plate 41. The mark plate detection mechanism 45 is used to detect whether there is a mark plate 41 in the mark supporting groove 42. Whenever the number of folded rear membrane cloths 10' in the storage assembly 3 reaches a predetermined number, the lower mark 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, the marking plate detection mechanism 45 and the label-dropping mechanism 46 can be programmed to cooperate 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.

[0027] Please refer to Figure 4 and Figure 5 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 an opening 411 and an upper edge 412 of the opening corresponding to the opening 411. The label supporting plate 442 is inserted into the opening 411 and supports the upper edge 412 of the opening to prevent the above-mentioned marking plate 41 from falling or the label supporting plate 442 withdraws from the opening 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, by using the support cylinder 441 and the lower mark cylinder 461 to drive the support plate 442 and the lower mark plate 462 respectively, the support and push-down of the marking plate 41 have high reliability and stability.

[0028] Please refer to Figure 4 and Figure 5 Specifically, the marking plate detection mechanism 45 includes a marking plate sensor 451 and a paddle 452. The paddle 452 includes a triggering portion 4521 and a force-bearing portion 4522. When the marking 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 marking plate 41 and moves so that the triggering portion 4521 triggers the marking plate sensor 451, thereby detecting that the marking plate 41 exists at the drop opening 421. When the force-bearing portion 4522 is not acted upon by the marking plate 41, the triggering portion 4521 does not trigger the marking plate sensor 451, thereby detecting that the marking plate 41 does not exist at the drop opening 421. In this way, it is possible to detect in real time whether the marking plate 41 exists at the drop opening 421, so that the user can 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 assembly 3 reaches a predetermined number for marking separation, thereby ensuring accurate counting of the predetermined number.

[0029] Please refer to Figure 4 and Figure 5Preferably, the counting mark assembly 4 includes a support plate 47, the support mark mechanism 44 and the 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, such as the mark plate sensor 451 using an infrared sensor, including a transmitting end and a receiving end with a gap therebetween, and the paddle 452 is pivotally supported on the support plate 47, and the trigger part 4521 and the force-bearing part 4522 are The support plate 47 is provided at opposite ends of the paddle 452 with a slot 472 for the force-bearing part 4522 to move therein. The force-bearing part 4522 rotates away from the slot 472 under the action of the marking plate 41 to drive the trigger part 4521 into the gap, thereby preventing the signal transmission and reception between the transmitting end and the receiving end. The force-bearing part 4522 rotates into the slot 472 without receiving the action of the marking plate 41 to drive the trigger part 4521 away from the gap, thereby allowing the signal transmission and reception between the transmitting end and the receiving end. Therefore, through the arrangement of this preferred embodiment, not only the overall structure of the counting mark assembly 4 is compact and each component works reliably, but also the force-bearing part 4522 of the paddle 452 can sensitively and synchronously drive the trigger part 4521 to move relatively in the gap according to the presence or absence of the force from the marking plate 41, thereby ensuring that the marking plate sensor 451 can accurately and reliably determine whether there is a marking plate 41 in the material trough 34.

[0030] Please refer to Figure 1 and Figure 3Specifically, the mask cloth folding machine further includes a mask cloth detector 5; 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 material pusher 31, a pair of transverse inserting knives 32, a film top cylinder 33 and a material trough 34. The two transverse inserting knives 32 are close to each other to prevent the folded rear film cloth 10' stored in the material trough 34 from moving toward the material pusher 31. There is a gap corresponding to the third folding knife 23 between the material pusher 31 and the transverse inserting knife 32, and the gap is used to accommodate the third folding knife 23 and the folded rear film cloth 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 5 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 then folds the mask cloth to obtain a folded back film cloth 10'. The third folding knife 23 transports the folded back film cloth 10' to the storage component 3 through the third fold forming groove, and the film pushing cylinder 33 pushes the folded back film cloth 10' onto the horizontal inserting knife 32 through the yield hole provided on the third folding knife 23 and presses it tightly. The third folding knife 23 returns to its original position. After the three-fold knife 23 returns to its original position, the folded rear film cloth 10' is located in the gap, the two horizontal inserting knives 32 move away from each other to make way, the pushing block 31 moves forward to push the folded rear film cloth 10' into the material slot 34, and the two horizontal inserting knives 32 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 rear film cloth 10' is stored in the material slot 34 under the obstruction of the horizontal inserting knife 32, and the folded rear film cloth 10' in the material slot 34 can be blocked 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 mask cloth, but also ensures that each folded rear film cloth 10' is sent to a position in the material slot 34 that does not interfere with the falling position of the marking plate 41.

[0031] Please refer to Figure 1 , Figure 4 and Figure 5Preferably, 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 to release 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, and the paired horizontal insert 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 also 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. The above-mentioned gap and the relative movement of the paired transverse knives 32 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.

[0032] Please refer to Figure 1 Preferably, the label holding slot 42 is inclined relative to the horizontal direction, and the marking plate 41 moves to the top of the drop port 421 under the action of its own gravity and the pressure of the pressure plate 43 and can be supported by the label holding mechanism 44, which prevents the marking plate 41 from failing to fill the vacant space left by the fallen marking plate 41 in time. The label lowering mechanism 46 also includes a guide plate 463 arranged 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 it is lowered into the gap. The material trough 34 includes two material trough guard plates arranged opposite to each other, and the storage assembly 3 also includes a material trough width adjustment hand wheel 37 for adjusting the distance between the two material 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 material trough 34.

[0033] 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 5, the folded mask cloth counter counts the number of mask cloths detected by the mask cloth detector 5, the controller is electrically connected to the mask cloth detector 5 and controls the operation of the label holding mechanism 44, the marking plate detection mechanism 45 and the label lowering mechanism 46 accordingly 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 rear mask cloth 10' reaches a predetermined number, and then automatically realize the control of the falling of the marking plate 41.

[0034] Please refer to Figure 3Preferably, the storage assembly 3 includes a stopper 35 and a trough film cloth sensor 36 respectively arranged inside and at the rear end of the material trough 34. The stopper 35 can prevent the folded rear film cloth 10' in the material trough 34 from falling over, thereby ensuring that the folded rear film cloth 10' stored in the material trough 34 is aligned and arranged in sequence in an upright manner, which is not only convenient for the subsequent one-time retrieval of each predetermined number of folded rear film cloths 10', but also ensures the reliable positioning of the marking plate 41 in the material trough 34. When the folded rear film cloth 10' in the material trough 34 is full, the stopper 35 approaches the trough film cloth sensor 36 under the action of the folded rear film cloth 10', and the trough film cloth sensor 36 generates a sensing signal to determine that the folded rear film cloth 10' in the material trough 34 is full and generates an alarm signal to prompt the machine to stop and wait for the folded rear film cloth 10' that has been counted and marked according to the predetermined number to be taken away. In this way, when the folded rear membrane cloth 10' is fully stored in the material slot 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 slot 34, causing adverse situations such as pushing material at the gap, interference and damage to components.

[0035] The above provides a facial mask cloth folding machine with a counting and marking function, but the counting and marking component 4 can also be changed into various forms. For example, the counting and 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 be set on both sides of the storage component 3 relative to the folding component 2. At this time, the lower opening 421 of the label supporting groove 42 in the counting and marking component 4 is no longer at the bottom of the label supporting groove 42, but on the two side surfaces of the end of the label supporting groove 42. At this time, there is no longer a label supporting mechanism 44 in the counting and marking component 4, and the marking plate 41 can be directly stored in the label supporting groove 42. When the folded rear membrane cloth 10' in the storage component 3 reaches a predetermined number, the lower marking mechanism 46 is set to move telescopically facing the two side surfaces of the end of the label supporting groove 42, so that the marking plate 41 in the label supporting groove 42 can be directly pushed horizontally into the storage component 3 through the lower opening 421, so as to achieve the technical effect of marking and separating the folded rear membrane cloth 10' in the storage component 3.

[0036] Finally, it should be understood that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
