[0011] In order to explain in detail the technical content, structural features, objectives and effects achieved by the technical means, detailed descriptions will be given below with reference to specific embodiments and drawings.

[0012] In the description of each embodiment of the present application, unless otherwise clearly specified or limited, the terms "first" and "second" are merely for explanatory purposes and should not be understood to indicate or imply relative importance. Unless otherwise specified or explained, the term "plurality" refers to two or more, including two. Terms such as "connected" and "fixed" should all be understood in a broad sense, for example, "connected" may be a fixed connection, a removable connection, an integral connection, an electrical connection, a direct connection, or an indirect connection via an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0013] In the description of each embodiment of the present application, in all drawings, the direction indicated by the arrow x is the longitudinal direction, the direction indicated by the arrow y is the width direction, and the direction indicated by the arrow z is the vertical direction. The horizontal direction is a direction parallel to a horizontal plane, and may be the longitudinal direction or the width direction. The horizontal direction not only includes a direction absolutely parallel to a horizontal plane, but also includes a direction approximately parallel to a horizontal plane that is usually recognized in engineering. The vertical direction is a direction perpendicular to a horizontal plane, and not only includes a direction absolutely perpendicular to a horizontal plane, but also includes a direction approximately perpendicular to a horizontal plane that is usually recognized in engineering. Note that all terms indicating orientation, such as "upper", "lower", "top", and "bottom", described in the present application, are understood to be relative to the vertical direction.

[0014] When using a tissue box, the front tissue at the outlet is pulled out, but the rear tissue is not sent out to the outlet due to the friction when the front tissue is pulled out, and the rear tissue is often left behind in the box body. In order to use the tissue box, the user must manually remove the succeeding tissues. In the process, the human hand comes into contact with the inside of the tissue box, which can easily contaminate the inside of the tissue box.

[0015] In addition, after the front tissue at the outlet has been pulled out, the frictional force applied to the rear tissue when the front tissue is pulled out is too great, or the tissues become bundled, which often results in multiple tissues being dispensed at the same time, resulting in tissue waste when used.

[0016] Based on this, in some embodiments, a transport mechanism is provided. As shown in Figures 3 and 5, the transport mechanism 1 includes at least one friction transport device 11 and at least one drive device 12. Here, each friction transport device 11 is used to frictionally engage with the tissue 100. Also, at least one drive device 12 is connected to at least one friction transport device 11, each drive device 12 is used to receive a drive signal, and upon receiving the drive signal, each drive device 12 is used to drive at least one friction transport device 11 to move the tissue in a specific moving direction.

[0017] As can be easily understood from the above, the conveying mechanism 1 includes at least one friction conveying device 11 and at least one driving device 12, and the driving device 12 is connected to at least one friction conveying device 11, and can drive at least one friction conveying device 12 to move the tissue in a specific moving direction according to the received driving signal, thereby realizing automatic conveying of the tissue 100, and when used in a tissue box, the tissue can be rationally sent out, which effectively avoids the contamination of tissue in the tissue consumable caused by human factors, and can prevent excess tissue from being sent out from the tissue sending side 41 of the tissue box, thereby avoiding the waste of tissue when used.

[0018] Specifically, in some embodiments, as shown in Figures 3, 5 and 6, one friction transport device 11 is provided, which is disposed opposite a predetermined conveying surface 3, and a gap 200 for transporting the tissue 100 is formed between the friction transport device 11 and the conveying surface 3, and the tissue 100 can be frictionally transported through the gap 200 to send out the tissue 100.

[0019] In some embodiments, as shown in Fig. 3 and Fig. 6, the driving device 12 is a motor-driven device, and the friction transport device 11 includes a friction member 111 and a transmission shaft 112. Here, the friction member 111 can rotate around a predetermined axis. Also, referring to Fig. 3, the friction member 111 is disposed opposite to the conveying surface 3, and a gap 200 is formed between the friction member 111 and the conveying surface 3. The transmission shaft 112 is coaxially connected to the friction member 111 along the predetermined axis. Also, as shown in Fig. 3, the transmission shaft 112 is further connected to the driving device 12. When the driving device 12 receives a driving signal, it can drive and rotate the friction member 111 through the transmission shaft 112, and further move the tissue 100 to move in a specific direction, and when used in a tissue box, it can realize automatic feeding of the tissue 100.

[0020] Also, in some embodiments, referring to Fig. 3 as well, the friction member 111 includes at least one friction wheel 1111 coaxially connected to the transmission shaft 112. Also, referring to Fig. 4 as well, the friction wheel 1111 includes a wheel body 11111 and a friction ring 11112. Here, referring to Fig. 3 and Fig. 4 as well, the wheel body 11111 is coaxially connected to the transmission shaft 112 and has a wheel outer surface around a predetermined axial direction, and the friction ring 11112 is sleeve-connected to the wheel outer surface of the wheel body 11111, and the friction ring 11112 is used to frictionally abut against the tissue 100.

[0021] 4, the friction ring 11112 includes an inner surface 111121 that is in close contact with the outer wheel surface of the wheel body 11111, and an outer surface 111122 that faces the inner surface 111121, and the outer surface 111122 is rough. In this way, the outer surface 111122 of the friction ring 11112 can come into contact with the tissue 100 when the friction wheel 1111 rotates, and the friction ring 11112 exerts a frictional force on the tissue 100 when it rotates, thereby realizing the transportation of the tissue 100.

[0022] It should also be noted that in some embodiments, as shown in Fig. 4, the outer surface 111122 of the friction ring 11112 is further provided with a plurality of grooves 111123 arranged around a predetermined axis. The grooves 111123 can make the outer surface 111122 of the friction ring 11112 granular, thus further improving the friction force generated by the outer surface 111122 of the friction ring 11112 against the tissue 100 when the friction ring 11112 rotates, so as to make the transport performance of the transport mechanism 1 for the tissue 100 more suitable.

[0023] In some embodiments, when there are multiple friction wheels 1111, the friction wheels 1111 may be arranged at equal intervals along a predetermined axial direction, as shown in Fig. 3. In this way, the friction force exerted on the tissue 100 by each friction wheel 1111 as it rotates can be uniformly distributed to the tissue 100, ensuring the flatness of the tissue 100 after it is sent out from the tissue sending side 41 of the tissue box, and preventing the tissue 100 from wrinkling during transportation.

[0024] Also, as an alternative solution, in another embodiment, as shown in FIG. 5, the friction member 111 is a friction roll coaxially connected to the transmission shaft 112, in this way, when the driving device 12 receives a driving signal, it can drive and rotate the friction roll via the transmission shaft 112, and the tissue 100 can be sent out from the tissue-sending side 41 of the tissue box by the friction force generated against the tissue 100 when the friction roll rotates.

[0025] Specifically, in some embodiments, referring to FIG. 6, the friction roll includes a roll body 1112 and a friction ring 1113. Here, the roll body 1112 is coaxially connected to the transmission shaft 112 and has a roll outer surface around a certain axial direction, and the friction ring 1113 is sleeve-connected to the roll outer surface of the roll body 1112 and extends along the axial direction of the roll body 1112. Of course, in practical application, the length of the friction ring 1113 can be increased or decreased according to specific needs, and in this embodiment, the length of the friction ring 1113 is not specifically limited, and the friction ring 1113 is used to frictionally contact the tissue 100.

[0026] 6, the friction ring 1113 includes an inner surface 11131 that is in close contact with the outer surface of the roll body 1112, and an outer surface 11132 that faces the inner surface 11131, and the outer surface 11132 is a rough surface. In this way, the outer surface 11132 of the friction ring 1113 can come into contact with the tissue 100 when the friction roll 13 rotates, and the friction ring 1113 exerts a frictional force on the tissue 100 when it rotates, thereby realizing the transportation of the tissue 100.

[0027] It should be noted that in some embodiments, as shown in Fig. 5, the friction roll is formed to extend along a predetermined axial direction, that is, the friction roll is formed to extend along the axial direction of the transmission shaft 112. In this way, when the friction roll cooperates with the conveying surface 3 to convey the tissue 100, the friction roll can be completely in contact with the tissue 100, and the friction force of the friction roll on the tissue 100 can be uniformly distributed on the tissue 100, so that the flatness of the tissue 100 can be ensured after the tissue 100 is sent out from the tissue sending side 41, and the occurrence of the wrinkle phenomenon during the conveying process of the tissue 100 can be avoided.

[0028] In some embodiments, as shown in FIG. 7 and FIG. 8, two friction transport devices 11 may be provided, namely, a first friction transport device 11a and a second friction transport device 11b, and the first friction transport device 11a and the second friction transport device 11b are provided facing each other and parallel to each other, and a gap 200 for transporting tissues is formed between the first friction transport device 11a and the second friction transport device 11b, and both the first friction transport device 11a and the second friction transport device 11b are used for frictionally contacting the tissues 100.

[0029] Next, as shown in Figures 7 and 8, the driving device 12 is connected to the first friction transportation device 11a and / or the second friction transportation device 11b, and the driving device 12 is used to drive the first friction transportation device 11a and / or the second friction transportation device 11b when receiving a driving signal, so that the tissue 100 can be transported by the first friction transportation device 11a and / or the second friction transportation device 11b. Based on this, it can be easily understood that by driving the first friction transportation device 11a and / or the second friction transportation device 11b by the driving device 12, the automatic transportation of the tissue 100 can also be realized, and the human interference can be avoided, and the situation in which the tissue 100 is contaminated during transportation due to the human influence can also be avoided.

[0030] Specifically, in some embodiments, as shown in Figures 7 and 8, the first friction transportation device 11a includes a first friction member 111a and a first transmission shaft 112a. Here, the first friction member 111a is rotatable around a first predetermined axial direction, and the first transmission shaft 112a is coaxially connected to the first friction member 111a along the first predetermined axial direction. Similarly, as shown in Figures 7 and 8, the second friction transportation device 11b includes a second friction member 111b and a second transmission shaft 112b. Here, the second friction member 111b is rotatable around a second predetermined axial direction, and, referring to Figure 2 as well, the second transmission shaft 112b is coaxially connected to the second friction member 111b along the second predetermined axial direction.

[0031] The first transmission shaft 112a is further connected to the driving device 12, and when the driving device 12 receives a driving signal, it drives and rotates the first friction member 111a via the first transmission shaft 112a, thereby providing a frictional force in the same direction tangent to the rotation direction between the first friction member 111a and the tissue 100, thereby realizing the transportation of the tissue 100. Alternatively, as shown in Figures 7 and 8, the driving device 12 may be connected to the second transmission shaft 112b, and when the driving device 12 receives a driving signal, it drives and rotates the second friction member 111b via the second transmission shaft 112b, thereby providing a frictional force in the same direction tangent to the rotation direction between the second friction member 111b and the tissue 100, thereby similarly realizing the transportation of the tissue 100.

[0032] In addition, since the structures of the friction member 111 described above can be adopted as the structures of the first friction member 111a and the second friction member 111b, it should be explained that detailed descriptions of the structures of the first friction member 111a and the second friction member 111b will be omitted.

[0033] In the above embodiment, two friction transport devices 11 are provided, namely, the first friction transport device 11a and the second friction transport device 11b. Therefore, in some embodiments, as shown in Fig. 9, the second friction transport device 11b may be provided on the top cover 5 of the tissue box, and when the bottom case 4 of the tissue box is opened or closed by the top cover 5, the second friction transport device 11b can move together with the top cover 5. After the bottom case 4 is closed by the top cover 5, a gap 200 for transporting tissues 100 can be formed between the second friction transport device 11b and the first friction transport device 11a.

[0034] Of course, as an alternative solution, in some embodiments, as shown in Figures 10 and 11, the conveying mechanism 1 further includes a holder 13 having a hinged side and a movable side spaced from the hinged side, where the movable side is connected to the second friction transport device 11b, the holder 13 is reversible relative to the first friction transport device 11a about the hinged side as a pivot axis, and the second friction transport device 11b is used to form a gap 200 for conveying the tissue 100 between the holder 13 and the first friction transport device 11a when the holder 13 is reversed to a predetermined position toward the first friction transport device 11a.

[0035] Also, as shown in FIG. 10, the driving device 12 can be connected to the first friction transport device 11a, so that when the driving device 12 receives a drive signal, it can drive the first friction transport device 11a so as to move the tissue 100 in cooperation with the second friction transport device 11b and transport it in a specific movement direction.

[0036] As can be easily understood from the above, the conveying mechanism 1 further includes a holder 13 having a hinged side and a movable side provided away from the hinged side, the holder 13 can be turned around with respect to the first friction transport device 11a with the hinged side as a pivot axis, and the second friction transport device 11b is provided on the movable side of the holder 13, so that when the holder 13 is turned around to a predetermined position with respect to the first friction transport device 11a, the second friction transport device 11b can form a gap 200 between the holder 13 and the first friction transport device 11a to transport the tissue 100. Therefore, referring to FIG. 1 as well, when the tissue consumable 10 needs to be replaced, the second friction transport device 11b can be moved away from the first friction transport device 11a simply by turning the holder 13 in a direction away from the first friction transport device 11a, and there is a sufficient open space for loading the tissue consumable 10 into the lower case 4 of the tissue box. 9 and 11, after the loading of the consumable tissue 10 is completed, simply pull out some of the tissues 100 and spread the pulled-out portion of the tissues on the first friction member 111a of the first friction transport device 11a, and then close the lower case 4 again with the top cover 5. This allows the second friction transport device 11b to clamp the tissues 100 again in cooperation with the first friction transport device 11a. This makes it easy to load the tissues into the conveying mechanism 1 and reduces contamination of the tissues 100 when they are loaded.

[0037] 11, the holder 13 includes a first holder body 131 and a second holder body 132 that are arranged opposite each other along the pivot axis, and the first holder body 131 has a first hinge connection end 1311, and the second holder body 132 has a second hinge connection end 1321. The first hinge connection end 1311 and the second hinge connection end 1321 are arranged coaxially along the pivot axis, and the first hinge connection end 1311 and the second hinge connection end 1321 together constitute a hinge connection side, and the second friction transport device 11b is arranged between the first holder body 131 and the second holder body 132.

[0038] 11, in some embodiments, the first holder body 131 includes a first upper connecting sheet 1312, a first supporting sheet 1313, and a first lower connecting sheet 1314. Here, the first supporting sheet 1313 is formed by folding a part of the first upper connecting sheet 1312 horizontally and extending toward the second holder body 132. Also, the first lower connecting sheet 1314 is formed by folding a part of the first supporting sheet 1313 vertically and extending away from the first upper connecting sheet 1312.

[0039] 11, the second holder body 132 includes a second upper connecting sheet 1322, a second supporting sheet 1323, and a second lower connecting sheet 1324. Here, the second supporting sheet 1323 is formed by folding a part of the second upper connecting sheet 1322 horizontally and extending toward the first holder body 131. Also, the second lower connecting sheet 1324 is formed by folding a part of the second supporting sheet 1323 vertically and extending in a direction away from the second upper connecting sheet 1322. Also, as shown in FIG. 11, the first hinge connection end 1311 is provided on the first upper connecting sheet 1312, the second hinge connection end 1321 is provided on the second upper connecting sheet 1322, and the second friction transport device 11b is provided between the first lower connecting sheet 1314 and the second lower connecting sheet 1324 and is connected to the first lower connecting sheet 1314 and the second lower connecting sheet 1324, respectively.

[0040] 10 and 11, the first hinge connection end 1311 of the first upper connecting sheet 1312 and the second hinge connection end 1321 of the second upper connecting sheet 1322 may be hinged to the lower case 4 of the tissue box, thereby realizing the inversion of the holder 13 relative to the first friction transportation device 11a. The first lower connecting sheet 1314 and the second lower connecting sheet 1324 can further realize the connection of the second friction transportation device 11b. Finally, as shown in FIG. 11, the first support sheet 1313 allows the first lower connecting sheet 1314 and the first upper connecting sheet 1312 to be misaligned, and the second support sheet 1323 allows the second lower connecting sheet 1324 and the second upper connecting sheet 1322 to be misaligned. In this way, when the first friction transport device 11a is connected to the first lower connecting sheet 1314 and the second lower connecting sheet 1324, respectively, the lower case 4 does not interfere with the installation of the first friction transport device.

[0041] 10, the holder 13 further includes a drive knob 133, and the drive knob 133 is provided on the first holder body 131 along the pivot axis. For example, the drive knob 133 may be provided on the first upper connecting sheet 1312, and the drive knob 133 is provided coaxially with the first hinge connecting end 1311 and the second hinge connecting end 1321. Based on this, when it is necessary to perform a tissue loading operation on the conveying mechanism 1, the entire holder 13 can be easily turned over by simply turning the drive knob 133, which makes it easy for the user to turn over the holder 13. In some embodiments, the drive knob 133 is provided on the first holder body 131 only, but it should be noted that the drive knob 133 may be provided on the second holder body 132 in practical application.

[0042] Also, in some embodiments, as shown in FIG. 9, the first frictional transportation device 11a further includes a first synchronous wheel 113a coaxially connected to the first transmission shaft 112a, and the second frictional transportation device 11b further includes a second synchronous wheel 113b coaxially connected to the second transmission shaft 112b. 9 and 11, when the holder 13 or the upper cover 5 is reversed to a predetermined position relative to the direction of the first friction transport device 11a, the second synchronous wheel 113b can mesh with the first synchronous wheel 113a. Therefore, when the driving device 12 drives the first transmission shaft 112a to rotate, the first transmission shaft 112a can synchronously drive the second transmission shaft 112b to rotate simultaneously due to the meshing of the first synchronous wheel 113a and the second synchronous wheel 113b. At this time, the first friction member 111a and the second friction member 111b can rotate relative to each other, and the second friction member 111b and the first friction member 111a can generate an active friction driving force against the tissue 100, which further improves the stability of the tissue 100 during transportation and prevents the tissue 100 from slipping during transportation. In addition, in some embodiments, as shown in FIG. 9, the diameters of the second synchronous wheel 113b and the first synchronous wheel 113a are the same, so that the rotational speeds of the first friction member 111a and the second friction member 111b are consistent during rotation, and the tissue 100 is prevented from being torn or wrinkled due to the difference in rotational speed between the first friction member 111a and the second friction member 111b during transportation, and the flatness of the tissue 100 during transportation is ensured.

[0043] As can be easily understood from the above, two friction transport devices 11 are provided in total, which are the first friction transport device 11a and the second friction transport device 11b. Based on this, as another alternative solution, in another embodiment, two driving devices 12 may be provided in the same manner, which are the first driving device 12a and the second driving device 12b, corresponding to the first friction transport device 11a and the second friction transport device 11b, as shown in Figures 12 and 13. Also, as shown in Figures 12 and 13, the first friction transport device 11a and the second friction transport device 11b are sequentially provided along the tissue conveying direction, and both the first friction transport device 11a and the second friction transport device 11b are used to frictionally contact the tissue 100 in the tissue box.

[0044] Also, as shown in Figures 12 and 13, the first driving device 12a is connected to the first friction transport device 11a. In practical application, referring to Figure 14, the first driving device 12a can drive the first friction transport device 11a to transport the tissue 100 toward the tissue delivery side 41 of the tissue box and deliver the tissue 100 from the tissue delivery side 41. Next, as shown in Figures 12 and 13, the second driving device 12b is connected to the second friction transport device 11b. Also, referring to Figure 14, the second driving device 12b is used to drive the second friction transport device 11b to transport the tissue 100 away from the tissue delivery side 41 until it is cut off when the length of the tissue 100 delivered from the tissue delivery side 41 of the tissue box reaches a predetermined length, and complete the delivery of the tissue of the predetermined length. Finally, also referring to FIG. 14, the second driving device 12b is further used to drive the second friction transport device 11b in the reverse direction so as to feed the succeeding tissue 100 into the first friction transport device 11a so that the next time the succeeding tissue is to be fed, after the tissue 100 has been pulled off, the first friction transport device 11a can continue to feed the succeeding tissue from the tissue delivery side 41 of the tissue box.

[0045] In addition, it should be noted that in addition to adopting the above-mentioned structure for the first friction transportation device 11a and the second friction transportation device 11b, that is, adopting a structure in which the first friction transportation device 11a realizes the transportation of tissues by the cooperation of the first friction member 111a and the first transmission shaft 112a, and the second friction transportation device 11b realizes the transportation of tissues by the cooperation of the second friction member 111b and the second transmission shaft 112b, in another embodiment, the first friction transportation device 11a and the second friction transportation device 11b may adopt other structures. For example, as shown in Figures 15 and 16, the first friction transportation device 11a includes a first upper friction member 114a, a first lower friction member 115a, a first upper transmission shaft 116a, and a first lower transmission shaft 117a. The second friction transportation device 11b includes a second upper friction member 114b, a second lower friction member 115b, a second upper transmission shaft 116b and a second lower transmission shaft 117b.

[0046] Here, in order to realize the transportation of the tissue 100, referring also to FIG. 17, the first upper friction member 114a and the first lower friction member 115a are provided facing each other and parallel to each other, and a first gap 200a capable of transporting the tissue 100 is formed between the first upper friction member 114a and the first lower friction member 115a. Next, the first upper transmission shaft 116a is coaxially connected to the first upper friction member 114a, and the first lower transmission shaft 117a is coaxially connected to the first lower friction member 115a, and the first upper transmission shaft 116a or the first lower transmission shaft 117a is further connected to the first driving device 12a. In addition, when the first upper transmission shaft 116a is connected to the first driving device 12a, as shown in FIG. 15 and FIG. 16, the first upper transmission shaft 116a can move and rotate the first upper friction member 114a by the driving action of the first driving device 12a. When the first lower transmission shaft 117a is connected to the first driving device 12a, the first lower transmission shaft 117a can move and rotate the first lower friction member 115a through the driving action of the first driving device 12a, as shown in Figures 15 and 16. Based on this, and referring to Figure 17 for easier understanding, the rotation of the first upper friction member 114a or the first lower friction member 115a causes the first upper friction member 114a and the first lower friction member 115a to generate frictional forces against the tissue 100, respectively, thereby realizing the relative rotation of the first upper friction member 114a and the first lower friction member 115a, and further allowing the tissue 100 to pass through the first gap 200a and be fed out.

[0047] In another embodiment, as shown in Figures 18 and 19, the first upper transmission shaft 116a and the first lower transmission shaft 117a may be connected to the first driving device 12a at the same time. In this manner, the first upper transmission shaft 116a and the first lower transmission shaft 117a can be driven simultaneously by the first driving device 12a to rotate relatively to each other. This increases the frictional force between the first upper friction member 114a and the first lower friction member 115a when transporting the tissue 100, prevents slippage during the process of transporting the tissue 100, and improves the transport accuracy of the tissue 100. Also, when the first driving device 12a is connected to the first upper transmission shaft 116a and the first lower transmission shaft 117a, as shown in FIG. 18, the first driving device 12a includes a first upper driving gear 121a coaxially connected to the first upper transmission shaft 116a, a first lower driving gear 122a coaxially connected to the first lower transmission shaft 117a, a first gear group 123a meshing with the first upper driving gear 121a and the first lower driving gear 122a, respectively, and a first motor assembly 124a connected to the first gear group 123a. In actual application, the first motor assembly 124a drives the first gear group 123a to transmit power while meshing with each other, and the first upper driving gear 121a and the first lower driving gear 122a transmit power while meshing with the first gear group 123a, thereby moving the first upper transmission shaft 116a and the first lower transmission shaft 117a respectively and rotating them relatively, thereby realizing the transportation of the tissue 100 by the first upper friction member 114a and the first lower friction member 115a.

[0048] It should also be noted that in some embodiments, as shown in FIG. 18, the first gear group 123a includes a first driving gear 1231a coaxially connected to the output shaft of the first motor assembly 124a and a first driven gear 1232a meshing with the first driving gear 1231a, and since the first driving gear 1231a and the first driven gear 1232a have the same diameter and the same number of teeth, when the first driving gear 1231a drives and rotates the first driven gear 1232a, the rotation speeds of the two gears can be matched. In addition, the first upper driving gear 121a meshes with the first driving gear 1231a, and the first lower driving gear 122a meshes with the first driven gear 1232a, so that the first gear group 123a realizes the relative rotation of the first upper driving gear 121a and the first lower driving gear 122a when they are engaged and transmitted, and further realizes the need to convey the tissue 100 by the first upper friction member 114a and the first lower friction member 115a. Of course, in some embodiments, the first lower driving gear 122a may mesh with the first driving gear 1231a, and the first upper driving gear 121a may mesh with the first driven gear 1232a, and by such an engagement manner, the first upper driving gear 121a and the first lower driving gear 122a can also realize the relative rotation when the first gear group 123a is engaged and transmitted.

[0049] In addition, in order to enable the second frictional transport device 11b to apply a frictional force to the tissue 100 in the direction opposite to that of the first frictional transport device 11a during the transport of the tissue 100, and to cut the tissue 100, in some embodiments, as shown in Fig. 17, the second upper frictional member 114b and the second lower frictional member 115b are provided facing each other and parallel to each other, and referring to Fig. 7 as well, a second gap 200b for passing the tissue 100 is formed between the second upper frictional member 114b and the second lower frictional member 115b. Next, the second upper transmission shaft 116b is coaxially connected to the second upper frictional member 114b, the second lower transmission shaft 117b is coaxially connected to the second lower frictional member 115b, and the second upper transmission shaft 116b or the second lower transmission shaft 117b is further connected to the second drive device 12b. When the second upper transmission shaft 116b is connected to the second driving device 12b, the second upper transmission shaft 116b can move and rotate the second upper friction member 114b through the driving action of the second driving device 12b, as shown in Figures 15 and 16. When the second lower transmission shaft 117b is connected to the second driving device 12b, the second lower transmission shaft 117b can move and rotate the second lower friction member 115b through the driving action of the second driving device 12b, as shown in Figures 15 and 16. Based on this, it is easy to understand that in actual application, the first frictional transport device 11a has a frictional force against the tissue in the direction of the tissue delivery side 41, and in the second frictional transport device 11b, the second upper frictional member 114b or the second lower frictional member 115b can actively generate a continuous frictional force between the tissue 100 and the second upper frictional member 114b or the second lower frictional member 115b through the rotation of the second upper frictional member 114b or the second lower frictional member 115b, which is tangential to the rotation direction, and the direction of this frictional force is directed away from the tissue delivery side 41, so that the tissue 100 is pulled straight and finally cut.Next, the second upper friction member 114b or the second lower friction member 115b is driven in the reverse direction by the second driving device 12b. At this time, referring to FIG. 17 as well, the friction direction of the second upper friction member 114b or the second lower friction member 115b against the tissue 100 becomes the same as the friction direction of the first friction transportation device 11a against the tissue 100, so that the remaining subsequent tissues 100 are replenished to the first friction transportation device 11a, and the subsequent tissues 100 are normally transported the next time the tissues are sent out from the tissue box.

[0050] However, as an alternative solution, in some embodiments, as shown in FIG. 19, the second upper transmission shaft 116b and the second lower transmission shaft 117b may be connected to the second driving device 12b at the same time. In this way, the second upper transmission shaft 116b and the second lower transmission shaft 117b can be driven simultaneously by the second driving device 12b to rotate relatively to each other. The second upper friction member 114b and the second lower friction member 115b can both actively generate friction force between themselves and the tissue 100. As a result, no slippage occurs during the process of transporting the tissue 100, and the pulling force on the tissue 100 is increased, making it easier for the tissue 100 to be pulled off. Also, when the second driving device 12b is connected to the second upper transmission shaft 116b and the second lower transmission shaft 117b, as shown in FIG. 19, the second driving device 12b includes a second upper driving gear 121b coaxially connected to the second upper transmission shaft 116b, a second lower driving gear 122b coaxially connected to the second lower transmission shaft 117b, a second gear group 123b that meshes with the second upper driving gear 121b and the second lower driving gear 122b, respectively, and a second motor assembly 124b connected to the second gear group 123b. In actual application, the second motor assembly 124b drives the second gear group 123b to transmit power while meshing with it, and the second upper driving gear 121b and the second lower driving gear 122b transmit power while meshing with the second gear group 123b, thereby moving the second upper transmission shaft 116b and the second lower transmission shaft 117b, respectively, to rotate relatively, thereby improving the pulling force of the tissue 100 by the second upper friction member 114b and the second lower friction member 115b.

[0051] It should also be noted that in this embodiment, as shown in FIG. 19, the second gear group 123b includes a second driving gear 1231b coaxially connected to the output shaft of the second motor assembly 124b, and a second driven gear 1232b meshing with the second driving gear 1231b, and since the second driving gear 1231b and the second driven gear 1232b have the same diameter and the same number of teeth, when the second driving gear 1231b drives and rotates the second driven gear 1232b, the rotation speeds of the two gears can be made to match. In addition, since the second upper driving gear 121b meshes with the second driving gear 1231b and the second lower driving gear 122b meshes with the second driven gear 1232b, the second gear group 123b realizes relative rotation between the second upper driving gear 121b and the second lower driving gear 122b when they are engaged and transmitted, and further increases the frictional force of the second upper friction member 114b and the second lower friction member 115b against the tissue 100, so that the tissue 100 can be pulled through. Of course, in some embodiments, the second lower driving gear 122b may mesh with the second driving gear 1231b and the second upper driving gear 121b may mesh with the second driven gear 1232b, and this type of meshing manner can also realize relative rotation between the second upper driving gear 121b and the second lower driving gear 122b when the second gear group 123b is engaged and transmitted.

[0052] It should be noted that the above-mentioned first upper friction member 114a, the first lower friction member 115a, the second upper friction member 114b and the second lower friction member 115b all have the same structure, and the same structure as that of the friction member 111 can be adopted for any of them, so a detailed description of the structures of the first upper friction member 114a, the first lower friction member 115a, the second upper friction member 114b and the second lower friction member 115b will be omitted here.

[0053] In some embodiments, as shown in Fig. 20, the tissue 100 has a plurality of gaps 1001 along its length that can be torn. In order to correspond to the gaps 1001, as shown in Fig. 20, the conveying mechanism 1 further includes a detection element 14, and referring to Fig. 21, the detection element 14 is electrically connected to the processor 6 of the tissue box, and is used to detect the tissue 100 conveyed between the first friction transport device 11a and the second friction transport device 11b in real time, and is used to upload the detected tissue data to the processor 6. In some embodiments, as shown in Figs. 8 and 9, a visual sensor may be used as the detection element 14, and it should be noted that the tissue data is image data of the tissue conveyed between the first friction transport device 11a and the second friction transport device 11b, obtained by the visual sensor. Alternatively, as shown in FIG. 20, a photoelectric sensor may be used as the detection element 14, and the tissue data is light leakage data of the tissue 100 transported between the first friction transport device 11a and the second friction transport device 11b detected by the photoelectric sensor.

[0054] When the first friction transport device 11a continuously sends out the tissues 100 from the tissue delivery side 41, the processor 6 further judges, based on the received tissue data, whether the length of the tissues 100 sent out from the tissue delivery side 41 has reached a first predetermined length, and when it is determined that the length has reached the first predetermined length, controls the second drive device 12b to drive the second friction transport device 11a to transport the tissues 100 in a direction away from the tissue delivery side 41.

[0055] Specifically, when a visual sensor is used as the detection element 14, referring also to FIG. 21, the visual sensor can upload the acquired image data of the tissue 100 to the processor 6, and the processor 6 compares this image data with pre-stored image data of the tissue 100 having a crack. When the comparison results of the two image data match, the processor can determine that the length of the tissue 100 delivered from the tissue delivery side 41 has reached a first predetermined length.

[0056] Similarly, when a photoelectric sensor is used as the detection element 14, referring to Figures 20 and 21 together, the photoelectric sensor can upload the detected light leakage data of the tissue 100 to the processor 6, and the processor 6 compares the light leakage data with pre-stored light leakage data of the tissue 100 having a crack, and when the comparison result of the two light leakage data matches, the processor 6 can determine that the length of the tissue 100 delivered from the tissue delivery side 41 has reached a first predetermined length.

[0057] In addition, when the second friction transport device 11b transports the tissue 100 in a direction away from the tissue delivery side 41, the processor 6 further judges whether or not the tissue 100 has been pulled through based on the received tissue data, and after determining that the tissue 100 has been pulled through, is used to control the second drive device 12b to drive the second friction transport device 11b to transport the tissue 100 a predetermined length in the direction of the tissue delivery side 41.

[0058] Specifically, when the tissue data acquired by the processor 6 is image data of the tissue 100 uploaded from the visual sensor, the processor 6 can compare the image data with pre-stored image data when the tissue is not pulled, as shown in Fig. 21, and when the comparison results of the two image data do not match, the processor 6 can determine that the tissue 100 has been pulled. Similarly, when the tissue data acquired by the processor 6 is light leakage data of the tissue 100 uploaded from the photoelectric sensor, the processor 6 can compare the light leakage data with pre-stored light leakage data when the tissue is not pulled, as shown in Fig. 10 and Fig. 11, and when the comparison results of the two light leakage data do not match, the processor 6 can determine that the tissue 100 has been pulled.

[0059] Finally, when the second friction transport device 11b conveys the following tissue 100 toward the tissue delivery side 41, referring to Fig. 20 and Fig. 21 together, the processor 6 is further used to turn off the first drive device 12a and the second drive device 12b after the following tissue 100 is delivered to the first friction transport device 1. This allows the following tissue 100 to be delivered in a timely manner by the conveying action of the first friction transport device 11a when it is necessary to deliver tissue again from the tissue box.

[0060] Also, some embodiments of the present application further provide a cutting mechanism. As shown in Fig. 22 and Fig. 23, the cutting structure 2 includes a cutter device 21 that moves along a predetermined linear direction and is used to cut the tissues 100 sent out from the tissue sending side 41 of the tissue box by the above-mentioned conveying mechanism 1, and a driving device 22 that is connected to the cutter device 21 and is used to drive the cutter device 21 to move along the predetermined linear direction, and also referring to Fig. 29, is further electrically connected to the processor 6 of the tissue box and is used to receive the first driving signal or the second driving signal output from the processor 6.

[0061] Also, both ends along the predetermined linear direction are the start position and the end position, and in some embodiments, referring to 22 and FIG. 29 together, when the driving device 22 receives a first driving signal output from the processor 6, it can drive the cutter device 21 to move from the start position to the end position. When the driving device 22 receives a second driving signal, it can drive the cutter device 21 to move from the end position to the start position.

[0062] For ease of understanding based on this, the cutter device 21 can be moved along a predetermined linear direction by driving the cutter device 21 with the drive device 22. Therefore, when the cutting mechanism 2 is used in a tissue box, the tissues sent out from the tissue sending side 41 of the tissue box by the transport mechanism 1 can be cut, and automatic tissue cutting can be similarly achieved.

[0063] 22 and 23, the cutter device 21 includes a cutter table 211 and a cutter 212. Here, the cutter table 211 is movable along a predetermined linear direction, and as shown in FIGS. 24 and 25, the cutter table 211 includes a cutter fixing holder 2111 and a connection assembly 2112 elastically connected to the cutter fixing holder 2111. The cutter 212 is rotatably connected to the connection assembly 2112, and the cutter 212 is used to cut the tissue 100 when the cutter table 211 moves along a predetermined linear direction, and the cutter 212 is further used to be movable relative to the tissue via the connection assembly 2112 when cutting the tissue.

[0064] As can be easily understood from the above, when the cutter 212 cuts tissue, if the tissue cannot be cut and gathers to one side, providing a large resistance to the movement of the cutter device 21, the cutter 212 can move directly across the tissue part providing resistance along its radial direction due to the elastic connection between the connection assembly 2112 and the cutter fixing holder 2111, effectively preventing the cutter device 21 from being firmly stopped during the cutting process.

[0065] Specifically, in some embodiments, as shown in Figures 24 and 25, a circular cutter is used as the cutter 212, and the circular cutter is rotatably connected to the connection assembly 2112. Therefore, when the cutter device 21 moves along a predetermined linear direction, the circular cutter can rotate due to the frictional resistance with the tissue 100, which improves the cutting force when the circular cutter cuts the tissue 100, and further improves the success rate of the cutter device 21 cutting the cut tissue 100 at one time. Of course, in some embodiments, a blade with another shape may be used as the cutter 212, and the structure and shape of the cutter 212 are not specifically limited here.

[0066] 24 and 25, in some embodiments, the cutter fixing holder 2111 has a top side 21111 and a bottom side 21112 opposite to the top side 21111, and the cutter fixing holder 2111 is provided with a mounting groove 21113 in a direction from the top side 21111 to the bottom side 21112, and a part of the circular cutter is accommodated in the mounting groove 21113 and another part protrudes from the mounting groove 21113. The part of the circular cutter protruding from the top side 21111 of the cutter fixing holder 2111 can cut the tissue.

[0067] In addition, in some embodiments, as shown in Figures 24 and 25, a springback region 21114 communicating with the mounting groove 21113 is further formed in the direction from the top side 21111 to the bottom side 21112 of the cutter fixing holder 2111, so that the circular cutter can move relative to the tissue when cutting the tissue, and the connection assembly 2112 can move the circular cutter up and down along its radial direction through the springback region 21114. It should be noted that in some embodiments, as shown in Figures 24 and 25, the connection assembly 2112 can be an elastic arm having a fixed end 21121 connected to the top side 21111 and a movable end 21122 provided away from the fixed end 21121, and the movable end 21122 is further connected to the axis of the circular cutter so as to be rotatable, and the elastic arm spans the entire springback region 21114 in the direction from the fixed end 21121 to the movable end 21122. It should also be noted that when providing the springback region 21114, the springback region 21114 may be formed to extend obliquely from the top side 21111 of the cutter fixing holder 2111 toward the mounting groove 21113, and of course, in some embodiments, the springback region 21114 may be formed to extend along a direction parallel to the mounting groove 21113.

[0068] Based on this, as shown in Figures 24 and 25, the spring back area 21114 allows a certain amount of retreat space to be provided below the elastic arm when the circular cutter is stopped, and the circular cutter can move toward the base 1112 of the cutter fixing holder 2111 via the elastic arm. After the circular cutter passes over the tissue part that provides resistance, it can quickly return due to the repulsive action of the elastic arm, thereby avoiding the phenomenon that the cutter device 21 is firmly stopped when cutting tissue.

[0069] 24, in some embodiments, the cutter fixing holder 2111 and the elastic arm may further be provided with a slit 21115 into which the circular cutter can be partially inserted, and the slit 21115 extends along a predetermined linear direction. By inserting the circular cutter into the slit 21115, the cutter fixing holder 2111 and the elastic arm can realize positional regulation of the circular cutter along the axial direction of the circular cutter, and can prevent the circular cutter from shaking when rotating. In addition, in order to realize a rotatable connection between the circular cutter and the movable end 21122 of the elastic arm, as shown in Figure 24, the circular cutter is further provided with a protruding shaft 2121 along its axial direction which is removably connected to the elastic arm, and a shaft hole 21123 into which the protruding shaft can be inserted is provided at the movable end 21122 of the elastic arm so as to correspond to the protruding shaft 2121.When the protruding shaft 2121 is inserted into the shaft hole 21123, a rotatable connection with the movable end 21122 is made possible, and rotation of the circular cutter can be realized by cooperation between the protruding shaft 2121 and the shaft hole 21123.

[0070] It should also be noted that the circular cutter can move relative to the tissue 100 through the elastic arm when cutting the tissue 100. As an alternative solution, in some embodiments, as shown in Fig. 26 and Fig. 27, the connection assembly 2112 includes a cutter movable holder 21124 and at least one elastic element 21125. Here, the cutter movable holder 21124 is provided in the mounting groove 21113 of the cutter fixed holder 2111, and the axis of the circular cutter is rotatably connected to the cutter movable holder 21124. Also, as shown in Fig. 26 and Fig. 27, each elastic element 21125 is provided between the groove bottom 211131 of the mounting groove 21113 and the cutter movable holder 21124, and the cutter movable holder 21124 can move relative to the groove bottom 211131 through the elastic element 21125.

[0071] As can be easily understood from the above, when the cutter device 21 moves along a predetermined linear direction, the circular cutter is rotatably connected to the cutter movable holder 21124, so that the circular cutter can rotate by frictional resistance with the tissue 100, improving the cutting force of the circular cutter on the tissue 100 and further improving the success rate of the cutter device 21 cutting the tissue at one time. Also, when the circular cutter is unable to cut the tissue when cutting and the tissue gathers on one side, providing a large resistance to the movement of the cutter device 21, as shown in FIG. 26, the circular cutter can directly go over the tissue part that has provided resistance along its radial direction due to the repulsive force of the elastic element 21125 provided between the cutter movable holder 21124 and the groove bottom 211131 of the mounting groove 21113, effectively avoiding the phenomenon that the cutter device 21 is firmly stopped during the cutting process.

[0072] Specifically, in order to realize a rotatable connection of the circular cutter to the cutter movable holder 21124, as shown in Figure 26, the cutter movable holder 21124 has a lower surface 211241 facing the groove bottom 211131 and an upper surface 211242 facing the lower surface 211241, and referring also to Figure 4, the cutter movable holder 21124 has an insertion groove 211243 in the direction from the upper surface 211242 to the lower surface 211241, and a part of the circular cutter is inserted into the insertion groove 211243, and the other part protrudes from the upper surface 211242 of the cutter movable holder 21124. As shown in Figures 26 and 27, the circular cutter has a protruding shaft 2121 formed along its axial direction, and the cutter movable holder 21124 is provided with a slide groove 211244 into which the protruding shaft 2121 can slide in the direction from the upper surface 211242 to the lower surface 211241, so as to correspond to the protruding shaft 2121 of the circular cutter. When the protruding shaft 2121 slides into the bottom of the slide groove 211244, it can be directly rotatably connected to the cutter movable holder 21124. In this way, the circular cutter can rotate due to the frictional resistance generated between it and the tissue 100 when cutting the tissue.

[0073] As a preferred solution, as shown in Fig. 26 and Fig. 27, the cutter movable holder 21124 has a side facing the groove bottom 211131 of the mounting groove 21113, which partly protrudes toward the groove bottom to form a position regulating post 21126. The groove bottom 211131 of the mounting groove 21113 has a position regulating hole (not shown) into which the position regulating post 21126 is inserted so as to correspond to the position regulating post 21126, and the position regulating post 21126 can slide along a direction perpendicular to the groove bottom 211131 via the position regulating hole. Based on this, as is easy to understand, the position regulating post 21126 and the position regulating hole cooperate to realize a guide for the movement of the cutter movable holder 21124, and the occurrence of a misalignment phenomenon when the cutter movable holder 21124 moves up and down along the radial direction of the circular cutter can be avoided.

[0074] In addition, when the circular cutter is stopped, the cutter movable holder 21124 is pressed downward quickly to move the circular cutter away from the tissue part that is providing resistance, and after passing the tissue part that is providing resistance, the cutter movable holder 21124 moves the circular cutter to return quickly. In some embodiments, as shown in Figures 26 and 27, the elastic element 21125 is a spring sleeve-connected to the position regulating post 21126, and the position regulating post 21126 can guide the pressing and rebounding of the spring, further improving the movement performance of the cutter movable holder 21124 in the up and down movement.

[0075] In addition, although only one position control post 21126 and one elastic element 21125 are provided, in some embodiments, the position control post 21126 and the elastic element 21125 may be increased according to actual usage requirements, and it should be noted here that the number of position control posts 21126 and the elastic elements 21125 is specifically limited.

[0076] In order to enable the driving device 22 to drive the cutter device 21 to move along a predetermined linear direction, in some embodiments, as shown in Fig. 22 and Fig. 23, the driving device 22 includes a belt pulley assembly 221 and a driving assembly 222. Here, the belt pulley assembly 221 includes a first synchronous wheel 2211 and a second synchronous wheel 2212 that are provided opposite to each other along the predetermined linear direction, and a synchronous belt 2213 that meshes with the first synchronous wheel 2211 and the second synchronous wheel 2212, respectively, and the synchronous belt 2213 is further connected to the cutter fixing holder 2111 of the cutter device 21. In some embodiments, as shown in Fig. 22 and Fig. 23, the driving assembly 222 includes a motor 2221 and a driving gear 2222 that is coaxially connected to the main shaft of the motor 2221, and the driving gear 2222 further meshes with the synchronous belt 2213. Also, referring to Figure 29, it should be noted that the motor 2221 of the drive assembly 222 is further electrically connected to the processor 6, and the motor 2221 can be used to receive a first drive signal and a second drive signal output from the processor 6, and the first drive signal or the second drive signal received by the motor 2221 can drive the drive gear 2222 to rotate in a forward or reverse direction, and the synchronous belt 2213 can drive the cutter device 21 to move linearly between the start position and the end position through the forward or reverse rotation of the drive gear 2222.

[0077] In addition, in order to further improve the stability when the drive assembly 222 drives the belt pulley assembly 221, as shown in Figures 22 and 23, the drive assembly 222 further includes a first tension pulley 2223 and a second tension pulley 2224, which are arranged opposite each other along a predetermined linear direction, and the synchronous belt 2213 is wound around the first tension pulley 2223 and the second tension pulley 2224, respectively, and the first tension pulley 2223 and the second tension pulley 2224 are used to improve the tension of the synchronous belt 2213, and the tension of the synchronous belt 2213 can be improved by the first tension pulley 2223 and the second tension pulley 2224. In this way, the stability when the drive assembly 222 drives the belt pulley assembly 221 is further improved, and the accuracy when the synchronous belt 2213 moves and slides the cutter table 211 is also improved.

[0078] However, as an alternative solution, in some embodiments, the belt pulley assembly 221 in the drive device 22 may be replaced by another transmission assembly. For example, as shown in FIG. 30, the transmission assembly 223 may be replaced by a lead screw transmission assembly, which includes a lead screw 2231 and a sliding bush 2232 sleeve-connected to the lead screw 2231. Here, the sliding bush 2232 and the lead screw 2231 are threadedly connected, and the lead screw 2231 is used to be rotatable about its own axis as a pivot axis, and the sliding bush 2232 is used to move along the axial direction of the lead screw 2231 when the lead screw 2231 rotates. Note that, as shown in FIG. 30, the cutter table 211 of the cutter device 21 may be fixedly connected to the sliding bush 2232, and the cutter device 21 is used to move together with the sliding bush 2232 when the sliding bush 2232 moves along the axial direction of the lead screw 2231.

[0079] Next, in order to drive and rotate the lead screw 2231, in some embodiments, the structure of the drive assembly 222 in the drive device 22 may be modified; for example, in addition to including the above-mentioned motor 2221, the drive assembly 222 may further include a reducer 2225 connected to the main shaft of the motor 2221, and one end of the lead screw 2231 may be connected to the output end of the reducer 2225, as shown in Fig. 30. Based on this, it can be easily understood that when the motor 2221 is started, it can drive the lead screw 2231 to rotate about its own axis as a pivot axis through the reducer 2225, and the sliding bush 2232 can move linearly along the axial direction of the lead screw 2231 when the lead screw 2231 rotates, so that after the tissue is sent out from the tissue box, the cutter device 21 can also cut the tissue 100 through the movement of the sliding bush 2232.

[0080] It should also be noted that in order to avoid the phenomenon that the sliding bush 2232 rotates simultaneously when the lead screw 2231 rotates, in some embodiments, as shown in FIG. 30 , the transmission assembly 223 further includes a guide member 2233 arranged parallel to the lead screw 2231. In addition, the guide member 2233 is further connected to the sliding bush 2232, and the guide member 2233 is used to guide the sliding bush 2232 when the sliding bush 2232 moves along the axial direction of the lead screw 2231.

[0081] For example, in some embodiments, referring to Fig. 31 as well, the guide member 2233 may be a slide rail, the slide rail is provided with a slideway 22331 parallel to a predetermined axial direction, and the slide bush 2232 is at least partially slidably fitted into the slideway 22331, so that when the lead screw 2231 rotates, the slide bush 2232 can slide along the longitudinal direction of the slideway 22331. Meanwhile, in another embodiment, as shown in Fig. 30, the guide member 2233 may be a guide rod, the guide rod passes through the slide bush 2232 and is slidably connected to the slide bush 2232, so that when the lead screw 2231 rotates, the slide bush 2232 can slide along the longitudinal direction of the guide rod. Based on this, for ease of understanding, by fitting the sliding bush 2232 into the slideway 22331 of the slide rail 2233, or by inserting a guide rod through the sliding bush 2232, it is possible to guide and regulate the position of the sliding bush 2232, thereby avoiding the phenomenon in which the sliding bush 2232 rotates simultaneously when the lead screw 2231 rotates.

[0082] 32, the transmission assembly 223 further includes a rack 2234 and a gear 2235. Here, the rack 2234 is arranged parallel to the lead screw 2231, and the gear 2235 is rotatably arranged on the sliding bush 2232 and meshes with the rack 2234. Therefore, the meshing of the gear 2235 and the rack 2234 can improve the stability when the sliding bush 2232 moves along the axial direction of the lead screw 2231.

[0083] Also, in some embodiments, as shown in FIG. 28, the cutting mechanism 2 further includes a detection device 23 composed of a first Hall element 231 and a second Hall element 232, and with reference to FIG. 29, the first Hall element 231 and the second Hall element 232 are further electrically connected to the processor 6, respectively. Thus, the first Hall element 231 can be used to detect the position of the cutter device 21 when the cutter device 21 moves toward the end position, and the first Hall element 231 is further used to output a first detection signal to the processor 6 when it detects that the cutter device 21 has moved to the end position. The second Hall element 232 is used to detect the position of the cutter device 21 when the cutter device 21 moves toward the start position, and the second Hall element 232 is further used to output a second detection signal to the processor 6 when it detects that the cutter device 21 has moved to the start position. 29, when the processor 6 receives the first detection signal, this means that the cutter device 21 has moved to the end position, and at this time the processor 6 can output a second drive signal to the drive device 22, which causes the drive device 22 to drive the cutter device 21 to move in the direction of the start position. When the processor 6 receives the second detection signal, this means that the cutter device 21 has moved to the start position and returned, and at this time the processor 6 can turn off the drive device 22.

[0084] As can be easily understood from the above, by detecting the position of the cutter device 21 using the first hall element 231 and the second hall element 232, the processor 6 can precisely control the driving device 22, and the cutting mechanism 2 can realize automated cutting during the transportation of tissues.

[0085] 23 and 28, in some embodiments, the cutting mechanism 2 includes a cutter hiding member 24. The cutter hiding member 24 is arranged along a predetermined linear direction. The cutter hiding member 24 has a lower surface 2412 facing the cutter table 211 and an upper surface 2411 facing the lower surface 2412. The cutter hiding member 24 is further provided with a cutter hiding slot 243, and the cutter hiding slot 243 further extends along a predetermined linear direction. In application, as shown in FIG. 23 and 28, a part of the circular cutter is fitted into the cutter hiding slot 243, and another part passes through the cutter hiding slot 243 and protrudes from the upper surface 2411 of the cutter hiding member 24, which part is used to cut the tissue 100 conveyed when the cutter device 21 moves along the predetermined linear direction.

[0086] Based on this, for easy understanding, by providing the cutter hiding member 24 and hiding a part of the circular cutter in the cutter hiding slot 243, the safety during use of the tissue box can be improved, and the user can be effectively prevented from being injured due to the user's erroneous operation during the cutting process of the circular cutter. It should be noted that in some embodiments, as shown in Fig. 23 and Fig. 28, the cutter hiding member 24 is actually composed of a cutter hiding bar 241 and a cover 242 provided on the lower case 4 of the tissue box, and the cutter hiding bar 241 and the cover 242 are separated from each other to form the cutter hiding slot 243. Of course, in some embodiments, the cutter hiding member 24 can be an integrated structural member, and the cutter hiding slot 243 is directly opened in the cutter hiding member 24 along a predetermined linear direction, where the structure of the cutter hiding member 24 and the manner of forming the cutter hiding slot 243 in the cutter hiding member 24 are not specifically limited.

[0087] In addition, other than adopting the form of the cutter device 21 in which the cutter table 211 and the cutter 212 are combined, it should be noted that in some embodiments, as another alternative solution, the cutter device 21 includes a cutter 212 that can rotate around a predetermined axis as a pivot axis, and a transmission assembly 213 connected to the cutter 212, as shown in Figures 34 and 35. Also, referring to Figure 33, when the driving device 22 drives the cutter device 21 to move along a predetermined linear direction, the transmission assembly 213 can further move the cutter 212 to rotate around the predetermined axis as a pivot axis, and the predetermined axis is the axis of the cutter 212 itself. Based on this, it can be easily understood that the linear movement of the cutter device 21 allows the transmission assembly 213 to move the cutter 212 to rotate synchronously, and the tissue is less likely to pile up on the cutter 212 and deform during the linear movement of the cutter 212, making it possible to more optimally cut the tissue, further ensuring that the cutter 212 can cut the tissue completely, the tissue can be cut in one go during the linear movement of the cutter device 21, and the flatness of the cross section of the tissue after cutting is ensured.

[0088] Specifically, in some embodiments, as shown in Figures 34 and 35, the cutter device 21 further includes a holder 214, and the cutter 212 and the transmission assembly 213 are both mounted on the holder 214; also referring to Figure 33, the cutter 212 is further rotatably connected to the holder 214, and the holder 214 is further connected to the drive device 22, so that the drive device 22 can drive the holder 214 to move along a predetermined linear direction.

[0089] In addition, in order to enable the transmission assembly 213 of the cutter device 21 to further move and rotate the cutter 212 when the driving device 22 drives the cutter device 21 to move along the predetermined linear direction, as shown in Fig. 33, the cutting mechanism 2 further includes a rack 25 extending along the predetermined linear direction, that is, the predetermined linear direction is the longitudinal direction of the rack 25. In addition, referring to Figs. 34 and 35 together, the transmission assembly 213 includes a first transmission shaft 2131, a driving gear 2132, a second transmission shaft 2133, a first driven gear 2134, and a second driven gear 2135, in correspondence with the rack 25. Here, as shown in Figures 34 and 35, the first transmission shaft 2131 is rotatably mounted on the holder 214, and the cutter 212 and the driving gear 2132 are both coaxially connected to the first transmission shaft 2131 along a predetermined axial direction, and after the cutter 212 and the driving gear 2132 are both attached to the first transmission shaft 2131, the driving gear 2132 can be positioned on either side of the cutter 212 along the predetermined axial direction.

[0090] In addition, as shown in Figures 34 and 35, the second transmission shaft 2133 may use the same mounting method as the first transmission shaft 2131, that is, the second transmission shaft 2133 may be similarly rotatably mounted on the holder 214, and the second transmission shaft 2133 may be further arranged parallel to the first transmission shaft 2131, and the first driven gear 2134 and the second driven gear 2135 are both coaxially connected to the second transmission shaft 2133. Also referring to Figures 33, it should be noted that the second driven gear 2135 meshes with the driving gear 2132, and the first driven gear 2134 meshes with the rack 25. 33, when the drive device 2 drives the holder 214 to move along a predetermined linear direction, the first driven gear 2134 meshes with the rack 25 to rotate, and when the first driven gear 2134 rotates, the second driven gear 2135 can be driven and rotated simultaneously via the second transmission shaft 2133, and when the second driven gear 2135 rotates, it meshes with the drive gear 2132, and the drive gear 2132 can further drive and rotate the first transmission shaft 2131, and the cutter 212 connected to the first transmission shaft 2131 can rotate. Based on this, for ease of understanding, the transmission assembly 213 allows the cutter device 21 to drive and rotate the cutter 212 while moving along a predetermined linear direction, and therefore the cutting force of the cutter 212 on the tissue 100 can be increased, making it easier to cut the tissue 100.

[0091] In addition, in some embodiments, the driving device 22 may have a different structure corresponding to the structure of the transmission assembly 213 so that the driving device 22 can drive the holder 214 to move along a predetermined linear direction. For example, as shown in FIG. 33, the driving device 22 includes a motor (not shown), a driving gear 225, a first synchronous wheel 226, a second synchronous wheel 227, and a synchronous belt 228. Here, as shown in FIG. 33, the driving gear 225 is coaxially connected to the main shaft of the motor, the first synchronous wheel 226 and the second synchronous wheel 227 are arranged opposite to each other along the predetermined linear direction, and the synchronous belt 228 is further meshed with the driving gear 225, the first synchronous wheel 226, and the second synchronous wheel 227, respectively, and the holder 214 is arranged between the first synchronous wheel 226 and the second synchronous wheel 227 and fixedly connected to the synchronous belt 228, as shown in FIG. 33 and FIG. 34. Thus, when the motor 224 drives the drive gear 225 to rotate, the drive gear 225 meshes with the synchronous belt 228 to synchronously move the synchronous belt 228 and transmit power, so that the first synchronous wheel 226 and the second synchronous wheel 227 can rotate by the transmission of the synchronous belt 228, and the linear movement of the holder 214 between the first synchronous wheel 226 and the second synchronous wheel 227 is realized, and the cutting of the tissue 100 by the cutter 212 is completed. In addition, in order to avoid the phenomenon that the synchronous belt 228 slips relative to the holder 214 when it is transmitted, referring also to FIG. 34, the holder 214 is provided with a tooth row 2141 that can mesh with the synchronous belt 228. Of course, in some embodiments, the holder 214 may be connected to the synchronous belt 228 in other ways, for example, a fastener such as a bolt may be used between the holder 214 and the synchronous belt 228. It should be noted that the connection method between the holder 214 and the synchronous belt 228 is not specifically limited.

[0092] In order to further improve the transmission performance when the synchronous belt 228 drives the holder 214 to move along a predetermined linear direction, in some embodiments, as shown in Fig. 33, the drive device 22 further includes a tension pulley 229, which is provided between the first synchronous wheel 226 and the second synchronous wheel 227, and the synchronous belt 228 is wound around the tension pulley 229. The tension pulley 229 not only realizes a guide for the synchronous belt 228, but also improves the tension of the synchronous belt 228 during transmission, and further improves the transmission performance of the synchronous belt 228.

[0093] In addition, in some embodiments, the cutter 212 may have other structures in addition to cutting the tissue 100 as a circular cutter, for example, as shown in Fig. 36, the cutter 212 has an inner side 2122 around a predetermined axis direction and an outer side 2123 facing the inner side 2122 and arranged coaxially. The outer side 2123 includes at least one blade edge 21231 around the predetermined axis direction. When one blade edge 21231 is provided, the cutter 212 may be a circular cutter.

[0094] 36, however, in some embodiments, a plurality of blade edges 21231 may be provided, and when a plurality of blade edges 1121 are provided, the blade edges 21231 may be provided sequentially around a predetermined axis direction, and the blade edges 21231 may further be connected sequentially around a predetermined axis direction, and the connection portion of two adjacent blade edges 21231 forms a blade angle 21232. Therefore, the cutting force on the tissue 100 when the cutter 212 rotates can be further improved, and the cutting effect on the tissue 100 can be more suitable, so that the tissue can be cut at one time during the linear movement process of the cutter 212, and the flatness of the cross section of the tissue 100 after cutting can be ensured.

[0095] It should also be noted that in some embodiments, the predetermined axial direction is the direction of the central axis of the cutter 212, and thus the cutter 212 can rotate about the central axis as a pivot axis, and as shown in Fig. 36, the cutter 212 has a total of eight cutting edges 21231, each of which has the same length, and the cutting edges 21231 adjacent to each other by two have the same cutting angle 21232. Based on this, for ease of understanding, the overall outer shape of the cutter 212 resembles a regular octagonal structure. Therefore, all cutting edges 21232 formed between two adjacent cutting edges 21231 by two are obtuse angles. Of course, in some embodiments, the number of the blade edges 21231 may be correspondingly increased or decreased as required, for example, when the number of the blade edges 21231 is three, the overall outline of the cutter 212 resembles an equilateral triangle, and the blade angles 21232 formed between two adjacent blade edges 21231 are all 60 degrees acute angles. It should be noted that each blade edge 21231 may be a straight edge, or may be a convex arc edge as shown in Fig. 36. When each blade edge 21231 is an arc edge, the cutting force of each blade edge 21231 on the tissue 100 can be further improved.

[0096] It should be noted that in order to facilitate the installation and fixing of the cutter 212 as a whole, as shown in Fig. 36, a part of the inner side 2122 of the cutter 212 protrudes in a direction away from the outer side 2123 to form a number of engagement protrusions 2124, which can engage and fix the cutter 212 to the first transmission shaft 2131, and the cutter 212 can be driven and rotated by the first transmission shaft 2131 through each engagement protrusion 2124. In order to further facilitate the engagement and fixing of the cutter 212 to the transmission shaft, the side of the engagement protrusion 113 away from the inner side is an inwardly recessed arc surface 21241, so that when the engagement protrusion 2124 is engaged with the first transmission shaft 2131, it can be fully engaged with the outer surface of the first transmission shaft 2131. In addition, in some embodiments, as shown in FIG. 4, each engagement protrusion 2124 is further arranged at equal intervals around the predetermined axial direction, and the multiple engagement protrusions 2124 enable the engagement force applied by the cutter 212 to the first transmission shaft 2131 to be uniformly distributed on the outer surface of the first transmission shaft 2131 around the predetermined axial direction, so that the installation stability and reliability of the cutter 212 can be ensured after the cutter 212 is installed.

[0097] Also, some embodiments provide a tissue box, as shown in Figures 1, 2 and 37, including a lower case 4, an upper cover 5, the above-mentioned conveying mechanism 1 and a processor 6. Here, the lower case 4 is used for mounting the tissue consumable 10, and the upper cover 5 is reversible relative to the lower case 4 and is used for opening and closing the lower case 4.

[0098] 3 and 5, the transport mechanism 1 is used to transport the tissues 100 in the tissue consumable 10 toward the tissue delivery side 41. Finally, referring to FIG. 37, the processor 6 is electrically connected to each of the driving devices 12 of the transport mechanism 1, and the processor 6 is used to receive a tissue delivery command, and after receiving the tissue delivery command, to output a driving signal to each of the driving devices 12, and when the driving signal is received, the driving device 12 drives at least one frictional transport device 11 to transport the tissues 100 toward the tissue delivery side 41.

[0099] Some embodiments further provide a tissue box, which, as shown in Figures 1, 2 and 38, includes the lower case 4, the upper cover 5, the conveying mechanism 1 and the processor 6 described above, and further includes the cutting mechanism 2 described above, as shown in Figure 22. The driving device 22 of the cutting mechanism 2 is further electrically connected to the processor 6.

[0100] In application, when the length of the tissue transported by the transport mechanism 1 reaches a predetermined length, the processor 6 can turn off the transport mechanism 1 and output a first drive signal to the drive device 22 of the cutting mechanism 2. When the drive device 22 receives the first drive signal, it drives the cutter device 21 of the cutting mechanism 2 to move from the start position to the end position, thereby realizing automatic cutting of the tissue 100. When the cutter device 21 moves to the end position, the processor 6 can output a second drive signal to the drive device 22 of the cutting mechanism 2. When the drive device 22 receives the second drive signal, it drives the cutter device 21 to move from the end position to the start position, thereby realizing the return movement of the cutter device 21.

[0101] Although the above embodiments have been described in this specification, it should be noted that there is no intention to limit the scope of protection of the present application. Therefore, any changes or modifications made to the embodiments described in this specification based on the novel concept of the present application, or any changes to structures or procedures having equivalent effects made according to the contents of the specification and drawings of the present application, and any direct or indirect application of the above technical means to other related technical fields, are all included in the scope of protection of the present application.
