[0002] In the field of beauty and skin care products, especially in the field of facial mask production, 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 packaging. However, at the time of packaging, 20 or 30 pieces of folded facial mask cloths need to be put into a facial mask bag. The current facial mask cloth folding machine does not have a counting and marking function, and the folded film cloths need to be counted manually before being put into the facial mask bag. This greatly wastes manpower, and 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, it is urgent to provide a facial mask cloth folding machine with high counting simplicity and a simple counting marking function. Utility Model Content

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] refer to Figures 1 to 6As one of the purposes of the present invention, a facial mask cloth folding machine with a simple counting and marking function is provided, which includes a film feeding belt 1, a folding assembly 2, a storage assembly 3, and a film pushing assembly 4. The film feeding belt 1 is used to transport facial mask cloth 10. The folding assembly 2 is arranged on the conveying path of the facial mask cloth 10 and is used to fold the facial mask cloth 10 multiple times to obtain a folded back film cloth 10'. The storage assembly 3 includes a material trough 34 and is used to store the folded back film cloth 10'. The film pushing assembly 4 is used to push each predetermined number of folded back film cloths 10' at different heights into the material trough 34, thereby forming a predetermined number of folded back film cloths 10' of different heights in the storage assembly 3, thereby clearly distinguishing the predetermined number of folded back film cloths 10'. Therefore, the facial mask cloth folding machine with a simple counting and marking function of the present invention, by providing the film pushing assembly 4, can push the folded back film cloths 10' into the material trough 34 according to the same or different predetermined numbers and corresponding to different heights. For example, the predetermined number of folded rear membrane cloths 10' in contact with the bottom surface of the trough 34 is set to 30 pieces, the predetermined number of folded rear membrane cloths 10' raised 20 cm relative to the bottom surface of the trough 34 is set to 25 pieces, and the predetermined number of folded rear membrane cloths 10' raised 40 cm relative to the bottom surface of the trough 34 is set to 20 pieces. The number of levels of height difference and the predetermined number can be set according to actual needs. Figure 1 As shown, in this embodiment, the number of levels of height difference is set to 2, and the predetermined number of folded rear membrane cloths 10' corresponding to the two levels of height is the same. Specifically, after the number of folded rear membrane cloths 10' that are folded and pushed into the trough 34 at the same height reaches a predetermined number, the folded rear membrane cloths 10' pushed into the trough 34 at the back are raised to a height for collection, thereby achieving the purpose of distinguishing the adjacent folded rear membrane cloths that have been counted. When the number of folded rear membrane cloths 10' that have been collected and raised to a height reaches the predetermined number again, the folded rear membrane cloths 10' that have been pushed into the trough 34 at the back are lowered to the original height for collection. In this way, subsequent workers can easily take away the folded rear membrane cloths 10' of different heights that have reached the set number for direct packaging. Of course, each group of folded rear membrane cloths 10' with a predetermined number does not necessarily have to be raised and collected. It is sufficient to raise the first or last piece of this group and collect it, which also achieves the purpose of distinguishing each group of folded rear membrane cloths 10' set to a predetermined number. It is only for comparative reference. Figure 3 、 Figure 4 and Figure 6The height level is set to 1, but it should be noted that in actual work, the pushing block 43 pushes the folded rear membrane cloth 10' into the material trough 34 at different heights according to the preset quantity, so that the user, such as a worker, can observe at a glance the folded rear membrane cloth 10' with a predetermined number at each height, thereby ensuring that the folded rear membrane cloth 10' will be packed into the mask bag in a uniform and accurate quantity. In addition, the folding rear membrane cloth 10' of the same height and located at the head and tail positions is in close contact with the folding rear membrane cloth 10' located in front of it under the action of the pushing block 43, and the friction between the contact surfaces of the two is sufficient to ensure that the folding rear membrane cloth 10' at the head and tail positions will not fall, and the folding rear membrane cloth 10' located between the head and tail will also maintain the same height under the action of the friction of the contact surfaces of the adjacent folding rear membrane cloths 10'. The part of the folding rear membrane cloth 10' located between the head and tail positions can drop. Even if the part of the folding rear membrane cloth 10' located between the head and tail positions drops, it will not cause counting errors to the predetermined number of folding rear membrane cloths 10' that actually belong to the same height level. Therefore, the folding rear membrane cloths 10' with a predetermined number of different heights can be easily and clearly distinguished. Moreover, since there is no need to add structures such as marking plates specifically for marking quantities, the effects of structural simplification, cost savings and stable operation are achieved.

[0027] Please refer to Figures 1 to 6 Specifically, the folding assembly 2 includes a folding knife 21, two folding knives 22 and three folding knives 23. The storage assembly 3 also includes a pair of horizontal inserting knives and a horizontal inserting knife driving device. The film pushing assembly 4 includes a lifting cylinder 41, a pushing cylinder 42, a pushing block 43, a film supporting plate 44 and a top film cylinder 45. The pushing cylinder 42 drives the pushing block 43 to move in or out relative to the material trough 34. The paired horizontal inserting knives include a paired outer horizontal inserting knives 31 and a paired inner horizontal inserting knives 32. There is a gap corresponding to the three folding knives 23 between the pushing block 43 and the outer horizontal inserting knife 31. The gap is used to accommodate the three folding knives 23 and the folding back film cloth 10'. The film supporting plate 44 is arranged at the bottom of the gap for supporting the folding back film cloth 10' in the gap. The lifting cylinder 41 can drive the pushing block 43, the film supporting plate 44 and the outer horizontal inserting knife 31 to perform lifting movements. In this way, by the above-mentioned mutual coordination of the folding assembly 2, the storage assembly 3 and the film pushing assembly 4, it can be ensured that the film pushing assembly 4 accurately pushes the folded rear film cloth 10' into the storage assembly 3 at different heights.

[0028] Please refer to Figure 5 and Figure 6Specifically, the pusher block 43 includes a plurality of transverse plates 431 arranged parallel and spaced in the direction of lift motion. A transverse slot 4311 is formed between any two adjacent transverse plates 431. The pair of outer transverse blades 31 includes a plurality of outer transverse blades 311 spaced parallel to each other, and the pair of inner transverse blades 32 includes a plurality of inner transverse blades 321 spaced parallel to each other, and the outer transverse blades 311 and the inner transverse blades 321 can pass through corresponding transverse slots 4311. This prevents the outer transverse blades 311 and the inner transverse blades 321 from interfering with each other's motion relative to the pusher block 43, ensuring reliable operation of each.

[0029] Please refer to Figures 1 to 6 Specifically, the folding component 2 also includes a film cloth detector 24. The film feeding belt 1 first transports the mask cloth 10 to the bottom of the first folding knife 21. After the film cloth detector 24 detects the mask cloth 10, the first folding knife 21 folds the mask cloth 10 into the first folding forming groove, and the second folding knife 22 folds the mask cloth 10 into the second folding forming groove. The third folding knife 23 then folds the mask cloth 10 to obtain the folded back film cloth 10'. The third folding knife 23 sends the folded back film cloth 10' to the gap, and the top film cylinder 45 pushes the folded back film cloth 10' onto the gap through the gap opened on the third folding knife 23. The outer horizontal inserting knife 31 is pressed, and after the three-folding knife 23 returns to its original position, the folded rear film cloth 10' is located in the gap to be supported by the film supporting plate 44, and the horizontal inserting knife driving device drives the two outer horizontal inserting knives 31 and the two inner horizontal inserting knives 32 to move away from each other and make way, and the pushing block 43 moves forward to push the folded rear film cloth 10' into the material groove 34, and the horizontal inserting knife driving device drives the two outer horizontal inserting knives 31 and the two inner horizontal inserting knives 32 to move closer to each other, and after the outer horizontal inserting knife 31 and the inner horizontal inserting knife 32 pass through the horizontal slot 4311 of the pushing block 43, the pushing block 43 retreats to its original position, thereby folding. The folded back film cloth 10' is stored in the material trough 34 under the obstruction of the inner horizontal inserting knife 32. When the folded back film cloth 10' in the material trough 34 reaches a predetermined number, the lifting cylinder 41 drives the pushing block 43, the film supporting plate 44 and the outer horizontal inserting knife 31 to rise, and the folded back film cloth 10' located in the gap is also lifted up. The two outer horizontal inserting knives 31 and the two inner horizontal inserting knives 32 move away from each other and make way. The pushing block 43 moves forward to push the raised folded back film cloth 10' into the material trough 34. In this way, the folding assembly 2 can reliably fold the mask cloth 10 and reliably. The folded rear membrane cloth 10' is transported to the gap, and the folded rear membrane cloth 10' on the membrane support plate 44 is positioned by using the pushing block 43 and the outer transverse insert 31. Then the membrane pushing assembly 4 reliably pushes a predetermined number of folded rear membrane cloths 10' into the material trough 34 at different heights. Then the inner transverse insert 32 blocks the folded rear membrane cloth 10' pushed into the material trough 34. In this way, the folded rear membrane cloth 10' maintains a relative position in the material trough 34, so that the folded rear membrane cloth 10' can form a height difference in the material trough 34 to achieve differentiation and counting.

[0030] In addition, the storage assembly 3 also includes a stopper 39 respectively provided inside and at the rear end of the trough 34. The stopper 39 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 that each folded rear membrane cloth 10' is reliably positioned in the trough 34. The storage assembly 3 also includes a trough width adjustment hand wheel 310 for adjusting the distance between the two trough guard plates, thereby adapting to the width of the folded rear membrane cloth 10', so that the folded rear membrane cloth 10' can be smoothly stored in the trough 34.

[0031] Please refer to Figure 5 Specifically, the lifting cylinder 41 can also drive the pushing cylinder 42 and the top film cylinder 45 to perform lifting movements, so that the structure of the film pushing component 4 can be simple and reliable.

[0032] Please refer to Figure 5 Specifically, the film pushing assembly 4 includes a lifting plate 46, with a film-pushing cylinder 45 and a material-pushing cylinder 42 disposed on both sides of the lifting plate 46. The lifting cylinder 41 is drivingly connected to the bottom surface of the lifting plate 46. The film-supporting plate 44 is fixedly connected to the lifting plate 46. When the material-pushing block 43 is in its original position, the film-supporting plate 44 extends beyond the end surfaces of the transverse plates 431 in the direction in which the material-pushing block 43 moves into the feed chute 34. In this way, the lifting cylinder 41 can reliably drive the relevant components to move up and down.

[0033] Please refer to Figure 5 and Figure 6 As a specific embodiment of driving the movement of the outer cross-cutting knife of the present invention, the storage assembly 3 also includes a pair of translation guide rods 35 and a pair of lifting guide rods 36. The cross-cutting knife driving device includes a pair of inner cross-cutting knife driving cylinders 33 respectively connected to the inner cross-cutting knife and arranged on both sides of the material trough 34. The translation guide rod 35 performs lifting movement under the drive of the lifting cylinder 41. A pair of lifting guide rods 36 are respectively fixedly connected to the pair of inner cross-cutting knives 32. The outer cross-cutting knives 31 arranged in pairs are respectively mounted on a translation guide rod 35 and can move away from or approach each other along the translation guide rod 35. The outer cross-cutting knives 31 arranged in pairs are respectively mounted on a lifting guide rod 36 and can perform lifting movement along the lifting guide rod 36. Therefore, the translation guide rod 35 provided can not only drive the two outer horizontal insert knives 31 to rise and fall, so that the folded rear membrane cloth 10' can be pushed into the material trough 34 at different heights limited by the outer horizontal insert knives 31, but also enable the two outer horizontal insert knives 31 to move smoothly towards or away from each other under the guidance of the balance guide rod 35. In addition, the lifting guide rod 36 provided can provide a good guiding effect for the lifting movement of the two outer horizontal insert knives 31.

[0034] Please refer to Figure 5 and Figure 6 , further specifically, a pair of translation guide rods 35 are respectively inserted and fixed in a fixing hole of a fixing block 37 fixed to the supporting plate 44, so that the translation guide rod 35 is reliably fixed to the supporting plate 44 and then lifted and lowered synchronously, and a plug-in block 38 with a through hole is provided on the outer surface of each outer horizontal inserting knife 31 facing away from the inner horizontal inserting knife 32, and the translation guide rod 35 is inserted into the through hole of the corresponding plug-in block 38, so that the translation guide rod 35 can reliably drive the corresponding outer horizontal inserting knife 31 to rise and fall relative to the inner horizontal inserting knife 32, and each outer horizontal inserting knife 31 is provided with a plurality of rings 312 sleeved on the outer periphery of the lifting guide rod 36, so that the outer horizontal inserting knife 31 can be smoothly lifted and lowered along the lifting guide rod 36.

[0035] Please refer to Figure 5 and Figure 6 Specifically, when the lifting cylinder 41 drives the translation guide rod 35 upward, the paired outer transverse blades 31 mounted on the translation guide rod 35 also rise along the lifting guide rod 36. When the pair of inner transverse blade 32 driving cylinders 33 drive the paired inner transverse blades 32 to move away from or toward each other, the paired outer transverse blades 31 mounted on the lifting guide rod 36, driven by the inner transverse blades 32, move away from or toward each other along the translation guide rod 35. The paired inner transverse blades 32 are driven by the inner transverse blade driving cylinders 33 to move away from or toward each other. Thus, the pair of inner transverse blade driving cylinders 33 can achieve the movement of the outer transverse blades 31 and the inner transverse blades 32 away from or toward each other.

[0036] Specifically, as another specific embodiment of the present invention for driving the outer horizontal blades 31, the horizontal blade drive device includes a pair of inner horizontal blade drive cylinders 33, each connected to the inner horizontal blades 32, and a pair of outer horizontal blade drive cylinders, each connected to the outer horizontal blades 31. An inner horizontal blade drive cylinder 33 and an outer horizontal blade drive cylinder are respectively provided on either side of the trough 34. The inner horizontal blade drive cylinders 33 and the outer horizontal blade drive cylinders respectively drive the paired inner horizontal blades 32 and the paired outer horizontal blades 31 away from or toward each other. A lifting plate 46 is fixedly connected to the lower portion of the paired outer horizontal blades 31. The lifting cylinder 41 drives the lifting plate 46 to lift and lower the paired outer horizontal blades 31 relative to the paired inner horizontal blades 32. Furthermore, the outer horizontal blades 31 and the inner horizontal blades 32 may each be provided with mating protrusions and slots in the vertical direction. Therefore, although a pair of inner transverse blade driving cylinders 33 and a pair of outer transverse blade driving cylinders are required to realize the movement of the inner transverse blade 32 and the outer transverse blade 31 away from or towards each other, the provision of the translation guide rod 35 and the lifting guide rod 36 can be omitted, saving assembly time.

[0037] Finally, it should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
