[0047] The embodiment of the present application first provides a paper cutting device. The paper cutting device provided in the embodiment of the present application can be used in food packaging structure production equipment or other production equipment with paper structure products.

[0048] The paper cutting device of the embodiment of the present application is described below with reference to the accompanying drawings.

[0049] Reference Figures 1 to 10 The paper cutting device 1 provided in the embodiment of the present application includes a frame 10, a material receiving mechanism 20, a cutting mechanism 30 and a conveying mechanism 40. The material receiving mechanism 20 is movably arranged on the frame 10 along the first direction X, and the material receiving mechanism 20 includes a plurality of material receiving mold positions 21 arranged in an array, and the material receiving mold positions 21 are used to receive sheet paper. The cutting mechanism 30 is arranged on the frame 10, and the cutting mechanism 30 is used to cut the strip paper 2 into sheet paper 3 with a shape similar to the material receiving mold position 21. The conveying mechanism 40 is arranged on the frame 10, and the conveying mechanism 40 includes a plurality of conveying units 40a distributed along the second direction Y, and the second direction Y is perpendicular to the first direction X. Along the first direction X, each conveying unit 40a is arranged opposite to a corresponding row of material receiving mold positions 21, and the conveying unit 40a is used to convey the sheet paper 3 to the corresponding material receiving mold position 21.

[0050] The strip-shaped paper material 2 may be a strip-shaped absorbent paper, silicone oil paper or other paper material structure.

[0051] The frame 10 is used to support the cutting mechanism 30 , the material receiving mechanism 20 , the conveying mechanism 40 and other mechanisms that the paper material cutting device 1 may include.

[0052] The frame 10 may be provided with a plurality of stations such as a cutting station, a feeding station and a receiving station, which are arranged in sequence along the production process of the paper material cutting device 1. The cutting mechanism 30 is arranged at the cutting station, and the conveying mechanism 40 is arranged at the feeding station.

[0053] The receiving mechanism 20 has a plurality of receiving mold positions 21, each of which is used to receive the sheet of paper 3 conveyed by the conveying mechanism 40. The plurality of receiving mold positions 21 are arranged in an array, in other words, the plurality of receiving mold positions 21 can be arranged into a plurality of rows spaced apart along the first direction X and a plurality of columns spaced apart along the second direction Y.

[0054] The receiving mechanism 20 can move bidirectionally in the first direction X. As the receiving mechanism 20 moves along the first direction X, each row of receiving mold positions 21 of the receiving mechanism 20 is alternately located at the receiving position of the frame 10 , thereby receiving the sheet paper 3 conveyed by the conveying mechanism 40 .

[0055] The paper cutting device 1 further includes a driving mechanism, which is used to drive the material receiving mechanism 20 to move along the first direction X. The driving mechanism may be disposed on the frame 10. Optionally, the driving mechanism may be a gear rack mechanism, a worm gear mechanism, a telescopic cylinder mechanism or other suitable driving mechanism.

[0056] The cutting mechanism 30 can cut the strip of paper 2 into sheet paper 3, and by reasonably selecting the cutter shape of the cutting mechanism 30 or controlling the cutting time cycle of the cutting mechanism 30, the cutting mechanism 30 can cut out sheet paper 3 that matches the splicing die position 21.

[0057] The matching of the sheet paper 3 and the splicing die position 21 means that the shape of the sheet paper 3 is similar to the shape of the splicing die position 21, the size of the sheet paper 3 is comparable to the size of the splicing die position 21, and after the splicing die position 21 receives the sheet paper 3, the position of the sheet paper 3 relative to the splicing die position 21 is fixed or not easy to change.

[0058] The material receiving mechanism 20 includes a base plate 22, and a plurality of material receiving molds 21 are detachably mounted on the base plate 22. The material receiving molds 21 can be detachably connected to the base plate 22 by screw connection, clamping or other suitable methods. Optionally, the material receiving molds 21 can be connected to the base plate 22 by screw connection to improve the convenience of disassembly and assembly of the material receiving molds 21 and enhance the connection strength between the material receiving molds 21 and the base plate 22.

[0059] The receiving die 21 can be detachably mounted on the base plate 22 , and the size of the receiving die 21 can be replaced and the position of the receiving die 21 can be adjusted according to actual needs, which is beneficial to improving the adaptability of the receiving mechanism 20 .

[0060] The plurality of conveying units 40a of the conveying mechanism 40 are arranged along the second direction Y, and each conveying unit 40a is arranged opposite to a corresponding row of the receiving die positions 21. In other words, the number of the conveying units 40a is the same as the number of the receiving die positions 21 in each row, that is, the number of the conveying units 40a is the same as the number of rows in which the receiving die positions 21 are arranged. Along the first direction X, each conveying unit 40a can be arranged opposite to a corresponding row of the receiving die positions 21, so as to facilitate conveying the sheet of paper 3 to the row of the receiving die positions 21.

[0061] When the receiving mechanism 20 moves along the first direction X to any row of receiving die positions 21 in the receiving station, the cutting mechanism 30 cuts to form a plurality of sheet paper materials 3, and the plurality of conveying units 40a can respectively convey the sheet paper materials 3 to the plurality of receiving die positions 21 in the row. Then, the receiving mechanism 20 continues to move along the first direction X to the next row of receiving die positions 21 in the receiving station, and the cutting mechanism 30 cuts again to form a plurality of sheet paper materials 3, and the plurality of conveying units 40a respectively convey the sheet paper materials 3 to the plurality of receiving die positions 21 in the next row. This is repeated until all rows of receiving die positions 21 receive the sheet paper materials 3, and the receiving mechanism 20 is fully loaded.

[0062] The paper cutting device 1 of the embodiment of the present application is provided with a movable material receiving mechanism 20, which has a plurality of material receiving mold positions 21 arranged in an array, and conveys sheet paper 3 to the plurality of material receiving mold positions 21 through a plurality of conveying units 40a. The material receiving mechanism 20 can simultaneously accommodate a plurality of sheet paper materials 3, so that a plurality of sheet paper materials 3 can be fed to a production device located downstream of the paper cutting device 1 at one time through the material receiving mechanism 20, which is conducive to realizing automatic feeding, improving product production efficiency, and reducing production safety hazards.

[0063] Furthermore, the cutting mechanism 30 can cut and form a sheet of paper 3 that matches the receiving die position 21. By using the receiving die position 21 to receive the sheet of paper 3, the position deviation between the sheet of paper 3 and the receiving die position 21 can be reduced, and the positions of multiple sheets of paper 3 can be unified, which is beneficial to improving the position accuracy of the sheet of paper 3 after feeding, improving the product production quality rate, and improving the product appearance.

[0064] In some embodiments, the cutting mechanism 30 includes a cutter 31, and along the vertical direction Z, the position of the cutter 31 is higher than the position of the material receiving mechanism 20, and the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other. The conveying unit 40a includes a conveying channel 41 for conveying the sheet paper 3, and the conveying channel 41 includes a first end 411 close to the cutter 31 and a second end 412 close to the material receiving mechanism 20, and the conveying channel 41 extends downward from the first end 411 to the second end 412.

[0065] The cutter 31 can cut the strip-shaped paper material 2 into sheet-shaped paper materials 3 by slitting, die-cutting or other suitable methods. The number of the strip-shaped paper material 2 can be one or more.

[0066] The cutting mechanism 30 may further include a driving structure for driving the cutter 31 to perform a cutting operation.

[0067] The first end 411 of the conveying passage 41 is close to the cutter 31 and can be opened toward the cutter 31, so that the sheet of paper 3 can enter the conveying passage 41. The second end 412 of the conveying passage 41 is close to the material receiving mechanism 20 and can be opened toward the material receiving mechanism 20, so that the sheet of paper 3 can be moved out of the conveying passage 41. The first end 411 is located at a higher position than the second end 412.

[0068] The conveying channel 41 may be closed along its own circumference, or partially closed, or open in a hollowed-out manner. For example, the conveying channel 41 may be a cylindrical channel closed along its circumference, or a semi-closed channel opened along one side of the circumference, or a hollowed-out channel with hollowed-out openings on multiple sides along the circumference.

[0069] The cutter 31 and the material receiving mechanism 20 have a position deviation in the vertical direction Z, and the conveying channel 41 extends obliquely from the cutter 31 to the material receiving mechanism 20. The sheet paper 3 in the conveying channel 41 can slide down to the material receiving mold position 21 under the action of its own gravity, and there is no need to set up an additional transfer mechanism, which is conducive to simplifying the structure of the paper cutting device 1 and reducing its cost and energy consumption.

[0070] In some embodiments, the conveying unit 40a includes two first stoppers 42 and at least one support member 43. The first stoppers 42 and the support member 43 are both arranged obliquely along the extension direction of the conveying channel 41, and the two first stoppers 42 are arranged opposite to each other and spaced apart along the second direction Y. Along the second direction Y, at least one support member 43 is located between the two first stoppers 42, and the support member 43 and the first stoppers 42 are arranged apart. The conveying channel 41 is formed between the two first stoppers 42 and is located on the upper side of at least one support member 43.

[0071] The conveying passage 41 being located on the upper side of at least one supporting member 43 means that the conveying passage 41 is located entirely directly above or laterally above the at least one supporting member 43 .

[0072] The two first limit members 42 are located on both sides of the conveying channel 41 along the second direction Y, and at least one support member 43 is located at the lower side of the conveying channel 41 . The first limit members 42 and the at least one support member 43 enclose at least part of the conveying channel 41 .

[0073] At least one supporting member 43 is used to support the sheet of paper 3 in the conveying passage 41 to reduce the risk of the sheet of paper 3 falling.

[0074] The number of the supporting member 43 may be one or more.

[0075] Optionally, if the conveying channel 41 is relatively small in size along the second direction Y, one support member 43 may be provided. If the conveying channel 41 is relatively large in size along the second direction Y, multiple support members 43 may be provided. Multiple support members 43 may be provided along the second direction Y side by side or at intervals.

[0076] The support member 43 and the first position-limiting member 42 are disposed separately, which means that the support member 43 and the first position-limiting member 42 are disposed separately, and the support member 43 is not connected to the first position-limiting member 42 .

[0077] The support member 43 may be a strip-shaped, rod-shaped or plate-shaped structure.

[0078] The first limiting member 42 may be a strip, rod or plate-shaped structure. Optionally, the first limiting member 42 may be a thin plate-shaped structure, and the thickness direction of the first limiting member 42 is parallel to the second direction Y, so that the first limiting member 42 has a larger limiting area in the vertical direction Z, which is conducive to improving the limiting effect of the first limiting member 42 on the sheet of paper 3.

[0079] The conveying channel 41 is formed between two first limiting members 42. The two first limiting members 42 can limit the sheet paper 3 in the conveying channel 41 along the second direction Y, which can reduce the possibility of the sheet paper 3 moving out of the conveying channel 41 and help the sheet paper 3 fall into the receiving mold position 21 more accurately.

[0080] The sheet of paper 3 is relatively light and is prone to jamming during transportation. To this end, the embodiment of the present application supports the sheet of paper 3 by at least one support member 43, and the support member 43 and the first stop member 42 are separated. A gap can be formed between the support member 43 and the first stop member 42, and a gap can also be formed between two adjacent support members 43, which can reduce the surface area of ​​the conveying unit 40a used to contact the sheet of paper 3, reduce the resistance encountered during the falling process of the sheet of paper 3, thereby reducing the risk of the sheet of paper 3 getting stuck, which is conducive to the conveying unit 40a to convey the sheet of paper 3 more smoothly.

[0081] In some embodiments, the support member 43 is rod-shaped, and the support member 43 has a smooth outer circumferential surface.

[0082] The supporting member 43 may extend straightly as a whole, or only the main body of the supporting member 43 may extend straightly, so as to stably support the sheet of paper material 3 .

[0083] The cross section of the support member 43 can be circular, and the portion of the support member 43 used to contact the sheet paper 3 is approximately a line, which is beneficial to reducing the contact area between the support member 43 and the sheet paper 3 to a large extent. In addition, the outer circumferential surface of the support member 43 used to contact the sheet paper 3 is smoothly arranged, which can further reduce the resistance during the transportation of the sheet paper 3 and reduce the risk of paper jams.

[0084] In some embodiments, the support member 43 includes a straight section 431 and a transition section 432 . The straight section 431 is inclined along the extension direction of the conveying channel 41 , and the transition section 432 is curved and extended from the lower end of the straight section 431 and gradually tends to be horizontal.

[0085] The straight section 431 extends straight and obliquely along the extending direction of the conveying passage 41. The straight section 431 forms a main body of the support member 43 for supporting the sheet-like paper material 3.

[0086] The straight section 431 has an upper end close to the cutter 31 and a lower end close to the material receiving mechanism 20. The transition section 432 is connected to the lower end of the straight section 431.

[0087] The transition section 432 may be bent and extended along a first arc curve, and the center of the circle where the first arc curve is located is located on the upper side of the transition section 432, so that the transition section 432 gradually bends upward.

[0088] The transition section 432 gradually tends to be horizontal, which means that the end of the transition section 432 away from the straight section 431 is in a horizontal state or a nearly horizontal state.

[0089] The straight section 431 and the transition section 432 are smoothly connected. Optionally, the straight section 431 and the transition section 432 are an integrally formed structure.

[0090] The straight section 431 of the support member 43 can stably support the sheet paper 3, which is conducive to the smooth movement of the sheet paper 3 in the conveying channel 41. The transition section 432 of the support member 43 is located at the end of the conveying channel 41. The transition section 432 can adjust the sheet paper 3 at the end of the conveying channel 41 to a horizontal or nearly horizontal posture, which is convenient for the sheet paper 3 to smoothly transition between the conveying channel 41 and the receiving die position 21, and is conducive to the sheet paper 3 entering the receiving die position 21 more smoothly.

[0091] In some embodiments, the first limiting member 42 includes a limiting body 421 and an outwardly extending portion 422 . The outwardly extending portion 422 is connected to the limiting body 421 and extends obliquely upward from the upper end of the limiting body 421 in a direction away from the other first limiting member 42 .

[0092] The limiting body 421 can be arranged obliquely along the extension direction of the conveying passage 41 , and the limiting body 421 has an upper end close to the cutter 31 and a lower end close to the material receiving mechanism 20 . The outward expansion portion 422 is connected to the upper end of the limiting body 421 .

[0093] The limiting body 421 and the outward expansion portion 422 are smoothly connected. Optionally, the limiting body 421 and the outward expansion portion 422 are an integrally formed structure.

[0094] The portion of the conveying channel 41 located between the outward expansion portions 422 of the two first stoppers 42 forms the starting section of the conveying channel 41, and along the conveying direction of the conveying channel 41, the size of the starting section in the second direction Y gradually decreases. Along the second direction Y, the size of the starting section of the conveying channel 41 is greater than the size of the portion of the conveying channel 41 located between the stopper bodies 421 of the two first stoppers 42.

[0095] During the process of the cutting mechanism 30 cutting the paper sheet 3 , the paper sheet 3 may be offset due to the adhesion of the cutter 31 , and the paper sheet 3 may deviate from the corresponding conveying passage 41 , thereby being blocked from entering the conveying passage 41 .

[0096] To this end, the two first stoppers 42 of the embodiment of the present application are both provided with an outward expansion portion 422, and the size of the starting section of the conveying passage 41 defined by the outward expansion portions 422 of the two first stoppers 42 is relatively large, which can reduce the possibility of interference between the sheet paper 3 and the outward expansion portion 422, and is conducive to the smooth entry of the sheet paper 3 into the conveying passage 41. In addition, the obliquely extended outward expansion portion 422 can also guide the sheet paper 3 entering the conveying passage 41, so that the sheet paper 3 smoothly enters the portion of the conveying passage 41 located between the stopper bodies 421 of the two first stoppers 42.

[0097] The portion of the conveying channel 41 located between the limiting bodies 421 of the two first limiting members 42 has a relatively small size in the second direction Y, which is conducive to more accurately defining the position of the sheet paper 3 in the second direction Y, thereby accurately conveying the sheet paper 3 to the receiving mold position 21 and improving the receiving efficiency.

[0098] In some embodiments, the conveying unit 40a includes a second limit member 44, which is inclined along the extension direction of the conveying channel 41, and the second limit member 44 is arranged at intervals on the upper side of at least one support member 43. The second limit member 44 and the first limit member 42 are arranged separately, and the conveying channel 41 is located on the lower side of the second limit member 44.

[0099] The second limit member 44 is disposed at intervals on the upper side of at least one support member 43, which means that the second limit member 44 is located directly above or above the side of at least one support member 43, and along the vertical direction Z, the second limit member 44 is spaced a certain distance from at least one support member 43.

[0100] The second stopper 44 is located on the upper side of the conveying channel 41, and the second stopper 44 may form a part of the conveying channel 41. Optionally, the conveying channel 41 may be enclosed by two first stoppers 42, at least one support member 43 and the second stopper 44.

[0101] Along the vertical direction Z, the projection of the second limiting member 44 may be located in the middle of the projection of the conveying channel 41 along the second direction Y, which is beneficial for achieving a better limiting effect on the sheet paper 3 with a smaller number of second limiting members 44 .

[0102] The second position-limiting member 44 and the first position-limiting member 42 are disposed separately, which means that the second position-limiting member 44 and the first position-limiting member 42 are disposed separately, and the second position-limiting member 44 is not connected to the first position-limiting member 42 .

[0103] A strip gap may be formed between the second limiting member 44 and the first limiting member 42, a strip gap may be formed between the first limiting member 42 and the supporting member 43, and a strip gap may also be formed between adjacent supporting members 43. The conveying channel 41 enclosed by two first limiting members 42, at least one supporting member 43 and the second limiting member 44 may be a hollow channel having a plurality of strip gaps.

[0104] The second limiting member 44 may be a strip-shaped, rod-shaped or plate-shaped structure.

[0105] Optionally, the second limit member 44 can be a thin plate-like structure, and the thickness direction of the second limit member 44 is parallel to the second direction Y, so as to enhance the structural strength of the second limit member 44 and reduce the space occupied by the second limit member 44 in the second direction Y, which is beneficial to increase the gap between the second limit member 44 and the first limit member 42, or arrange other structures (such as subsequent positioning members) in the gap, which is beneficial to improve the compactness of the structure and reduce the volume.

[0106] The second stopper 44 is disposed on the upper side of the conveying passage 41, and the second stopper 44 can limit the sheet of paper 3 in the conveying passage 41 along the vertical direction Z, thereby reducing the risk of the sheet of paper 3 moving out of the conveying passage 41 from above. Furthermore, when a paper jam occurs in the conveying passage 41, the position or state of the sheet of paper 3 can be adjusted through the gap between the second stopper 44 and the first stopper 42, which is conducive to quickly resolving the paper jam.

[0107] In some embodiments, the bottom surface of the second limiting member 44 is not higher than the top surface of the first limiting member 42 .

[0108] The bottom surface of the second stopper 44 may be flush with the top surface of the first stopper 42, or the bottom surface of the second stopper 44 may be lower than the top surface of the first stopper 42. Thus, no gap extending along the second direction Y is formed between the first stopper 42 and the second stopper 44, which is beneficial to further reduce the risk of the sheet of paper 3 moving out of the conveying passage 41.

[0109] In some embodiments, the conveying unit 40 a includes two support members 43 , and the two support members 43 are spaced apart along the second direction Y. A projection of the second stopper 44 along the vertical direction Z is located between projections of the two support members 43 along the vertical direction Z.

[0110] The two support members 43 can support the sheet paper 3 at different positions in the second direction Y, respectively, to improve the support stability of the sheet paper 3, reduce the risk of the sheet paper 3 falling, and also help to reduce the tilting phenomenon of the sheet paper 3, improve the stability of the sheet paper 3 moving in the conveying channel 41, and help the receiving mold position 21 to align and receive the sheet paper 3 more accurately.

[0111] The projection of the second limit member 44 is located between the two support members 43, and the position where the second limit member 44 applies force to the paper sheet 3 is located between the positions where the two support members 43 apply force to the paper sheet 3, which is beneficial to reducing the shaking of the paper sheet 3 during the conveying process, so that the paper sheet 3 maintains a stable posture in the conveying channel 41, which is beneficial for the receiving mold position 21 to align and receive the paper sheet 3 more accurately.

[0112] In some embodiments, reference Figure 7 A first guide surface 441 is provided on the upper end of the second limit member 44 facing the conveying passage 41 . The first guide surface 441 is an arc-shaped surface convex in a direction away from the conveying passage 41 .

[0113] The center of the circle corresponding to the first guide surface 441 is located at the lower side of the first guide surface 441 .

[0114] The first guide surface 441 can be smoothly configured to reduce the resistance of the first guide surface 441 to the sheet of paper 3 .

[0115] The cutter 31 can cut the strip of paper 2 along the vertical direction Z to improve the cutting effect. The sheet of paper 3 formed after the cutter 31 cuts the strip of paper 2 is placed roughly in the horizontal direction. The sheet of paper 3 that has just entered the conveying channel 41 tends to be horizontal and gradually contacts the first guide surface 441. The arc-shaped first guide surface 441 can smoothly guide the sheet of paper 3, thereby adjusting the direction of the sheet of paper 3 with less resistance, which is conducive to the sheet of paper 3 entering the conveying channel 41 more smoothly.

[0116] In some embodiments, a second guide surface 442 is provided at a side of the lower end of the second limiting member 44 facing the conveying passage 41 . The second guide surface 442 is an arc-shaped surface convex toward the conveying passage 41 .

[0117] The center of the circle corresponding to the second guide surface 442 is located on the upper side of the second guide surface 442 .

[0118] The second guide surface 442 can be smoothly configured to reduce the resistance of the second guide surface 442 to the sheet of paper 3 .

[0119] The sheet of paper 3 gradually tends to be horizontal under the guidance of the transition section 432. The second guide surface 442 can provide space for the posture adjustment of the sheet of paper 3, and can also limit the sheet of paper 3 downward during the process of adjusting the posture of the sheet of paper 3, thereby reducing the possibility of the sheet of paper 3 arching upward, which is conducive to improving the smoother entry of the sheet of paper 3 into the receiving mold position 21.

[0120] In some embodiments, reference Figure 3 The conveying mechanism 40 includes a plurality of support members 43 spaced apart along the second direction Y, and at least one support member 43 is disposed between two adjacent conveying units 40a. The conveying mechanism 40 includes a support frame 45, and the support frame 45 includes a first beam 451 extending along the second direction Y, and the first stopper 42 is detachably connected to the first beam 451.

[0121] The plurality of support members 43 may be arranged at equal intervals along the second direction Y, or may be arranged at unequal intervals.

[0122] A portion of the plurality of support members 43 is located between two first stop members 42 of the plurality of conveying units 40a and forms a portion of the plurality of conveying units 40a. Another portion of the plurality of support members 43 is located between two adjacent conveying units 40a.

[0123] The first position-limiting member 42 may be supported on the support frame 45 through the first beam 451 , and the support frame 45 may be fixed on the frame 10 .

[0124] The first limiting member 42 may be detachably connected to the first beam 451 by screw connection, clamping or other suitable means.

[0125] The first beam 451 extends along the second direction Y. Through the detachable connection between the first stopper 42 and the first beam 451, the position of the first stopper 42 in the second direction Y can be adjusted as required, thereby adjusting the spacing between the two first stoppers 42, so that the size of the conveying channel 41 in the second direction Y matches the size of the sheet paper 3 in the second direction Y. Therefore, only the corresponding material receiving mechanism 20 needs to be replaced to make the paper cutting device 1 suitable for cutting strip paper 2 of various sizes, which is conducive to expanding the applicable range of the paper cutting device 1.

[0126] Furthermore, after the position of the first limiting member 42 in the second direction Y is adjusted, the number of the supporting members 43 of each conveying unit 40 a will also change accordingly, which is beneficial to improving the supporting effect for the sheet paper materials 3 of various sizes.

[0127] In some embodiments, reference Figure 3 and Figure 6 The conveying mechanism 40 includes a conveying roller 46 rotatably supported on the frame 10 , and the rotation axis of the conveying roller 46 extends along the second direction Y. The conveying roller 46 is used to convey the sheet paper 3 cut by the cutting mechanism 30 to the conveying channel 41 .

[0128] Optionally, the conveying roller 46 may be supported on the support frame 45. The support frame 45 may include two support plates 452 disposed opposite to each other along the second direction Y, and the conveying roller 46 is rotatably supported on the two support plates 452.

[0129] The conveying mechanism 40 may further include a first driving mechanism, which is disposed on the supporting plate 452 of the supporting frame 45 and is used to drive the conveying roller 46 to rotate.

[0130] The conveying roller 46 may be disposed adjacent to the cutter 31. Alternatively, the conveying roller 46 may be disposed between the cutter 31 and the conveying unit 40a, and at least a portion of the conveying roller 46 may also form a portion of the enclosed conveying passage 41.

[0131] There may be one or more conveying rollers 46 . The plurality of conveying rollers 46 may be distributed along the conveying direction of the sheet-like paper material 3 .

[0132] The sheet of paper 3 can contact the conveying roller 46. The conveying roller 46 can use friction to produce a transmission effect on the sheet of paper 3, so that the sheet of paper 3 can enter the conveying channel 41 more effectively, which is conducive to improving the conveying efficiency of the sheet of paper 3.

[0133] In some embodiments, reference Figure 6 The conveying roller 46 includes a conveying shaft 461 and a plurality of convex rings 462 disposed around the conveying shaft 461 . The plurality of convex rings 462 are disposed at intervals along the second direction Y. Each conveying channel 41 corresponds to at least one convex ring 462 .

[0134] The convex ring 462 is fixedly arranged relative to the transmission shaft 461 and can rotate synchronously with the convex ring 462 .

[0135] The convex ring 462 can be integrally formed with the transmission shaft 461 , and the convex ring 462 can also be connected to the transmission shaft 461 by contour connection, snap connection, interference fit, sleeve connection or other suitable methods.

[0136] The conveying channel 41 corresponds to at least one convex ring 462, which means that at least one convex ring 462 is arranged corresponding to the conveying channel 41 and transmits the sheet of paper 3 toward the conveying channel 41. The convex ring 462 corresponding to the conveying channel 41 can form a part of the enclosed conveying channel 41. For example, the convex ring 462 corresponding to the conveying channel 41 can be located at the lower side of the conveying channel 41.

[0137] The number of protruding rings 462 corresponding to each conveying channel 41 may be the same or different.

[0138] The provision of the convex ring 462 can reduce the area of ​​the conveying roller 46 that contacts the sheet paper 3 , reduce the possibility of the sheet paper 3 adhering to the conveying roller 46 , and facilitate the smooth transportation of the sheet paper 3 .

[0139] In some embodiments, reference Figure 3 and Figure 6 The conveying mechanism 40 includes a plurality of support members 43, which are arranged at intervals along the second direction Y, and are arranged obliquely along the extending direction of the conveying channel 41. At least one support member 43 is arranged at the lower side of each conveying channel 41. Along the extending direction of the conveying channel 41, the plurality of support members 43 and the plurality of convex rings 462 of the conveying roller 46 are arranged one by one.

[0140] Along the extending direction of the conveying passage 41 , each support member 43 is aligned with a corresponding protruding ring 462 .

[0141] The plurality of support members 43 may all be distributed on the lower side of the plurality of conveying channels 41 , or only a portion of the support members 43 may be distributed on the lower side of the plurality of conveying channels 41 , and the other portion of the support members 43 may be located between two adjacent conveying channels 41 .

[0142] The plurality of support members 43 may be supported on the support frame 45. Optionally, the support frame 45 may include a second beam 453 extending along the second direction Y, and the plurality of support members 43 may be connected to the second beam 453 by welding, bonding, clamping or other suitable means. The second beam 453 may be rod-shaped and pass through the first stopper 42.

[0143] The extending direction of the conveying path 41 is substantially parallel to the conveying direction of the sheet of paper 3 .

[0144] Along the extension direction of the conveying passage 41, the supporting position of the sheet paper 3 by the convex ring 462 is aligned with the supporting position of the sheet paper 3 by the support member 43. In the process of the sheet paper 3 transitioning from the convex ring 462 to the support member 43, the support member 43 can take over the support of the convex ring 462 to support almost the same area of ​​the sheet paper 3, which is beneficial to reduce the possibility of interference between the sheet paper 3 and the support member 43 and reduce the risk of paper jam.

[0145] In some embodiments, reference Figure 8 and Fig. 9 The upper side of the receiving die 21 is provided with a recess 211, and the projection of the recess 211 matches the projection of the sheet paper 3 in the vertical direction Z. The receiving die 21 is provided with an opening 212 on one side along the first direction X, and the opening 212 is connected to the recess 211, so that the sheet paper 3 conveyed through the conveying channel 41 is received in the recess 211 through the opening 212.

[0146] The concave portion 211 is sunken downwardly from the upper surface of the receiving die 21 .

[0147] The projection of the concave portion 211 matches the projection of the paper sheet 3, which means that the projection shape of the paper sheet 3 is similar to the projection shape of the concave portion 211, and the projection size of the paper sheet 3 is roughly equivalent to the projection size of the concave portion 211. Thus, the paper sheet 3 can be exactly accommodated in the concave portion 211, and the concave portion 211 can limit the position of the paper sheet 3.

[0148] When the receiving die 21 is in the receiving station, the opening 212 may be located on the side of the receiving die 21 facing the conveying mechanism 40 to allow the sheet paper 3 conveyed by the conveying mechanism 40 to enter the recess 211 through the opening 212 .

[0149] Along the first direction X, the projection of the recess 211 may be located within the projection of the opening 212. In some examples, the projection of the opening 212 may completely overlap with the projection of the recess 211, and the area of ​​the opening 212 is substantially equal to the cross-sectional area of ​​the recess 211. In other examples, the projection of the opening 212 may also be partially outside the projection of the recess 211, and the area of ​​the opening 212 is greater than the cross-sectional area of ​​the recess 211. Thus, it is beneficial for the sheet of paper 3 to enter the recess 211 more smoothly through the opening 212.

[0150] In the embodiment of the present application, an opening 212 is provided on one side of the receiving die position 21 along the first direction X, so that the sheet paper 3 output from the conveying channel 41 can automatically slide into the recess 211 through the opening 212, thereby realizing automatic receiving of the paper, which is beneficial to simplifying the structure of the paper cutting device 1 and reducing its cost and energy consumption.

[0151] The splicing die 21 provided in the embodiment of the present application forms a recess 211 on its upper side to accommodate the sheet paper 3 , has a simple structure, is conducive to reducing design costs, reduces the failure rate of the splicing process, and improves the reliability of the paper cutting device 1 .

[0152] In some embodiments, the receiving die 21 includes a plurality of suction cups 213 disposed in the recess 211 , and the suction cups 213 are used to absorb the sheet of paper 3 .

[0153] The suction cup 213 can absorb the sheet of paper 3 by vacuum means or other suitable means.

[0154] The plurality of suction cups 213 may be arranged along the first direction X, or along the second direction Y, or in an array to improve adsorption stability.

[0155] The plurality of suction cups 213 may be evenly distributed in the concave portion 211 to produce a more balanced adsorption effect on the sheet of paper 3 and reduce the phenomenon that the sheet of paper 3 is lifted up due to uneven force.

[0156] The suction cup 213 can enhance the holding capability of the receiving die 21 on the paper sheet 3 , and reduce the risk of the paper sheet 3 shifting in the receiving die 21 or even escaping from the receiving die 21 .

[0157] In some embodiments, reference Figure 3 and Fig.10 The paper cutting device 1 further includes a positioning mechanism 50 , which is used to push the sheet of paper 3 along the first direction X so that the sheet of paper 3 is accommodated in the recess 211 .

[0158] The direction of the pushing action of the positioning mechanism 50 on the paper sheet 3 may be consistent with the direction in which the paper sheet 3 enters the recess 211 .

[0159] The friction between the wall of the concave portion 211 and the paper sheet 3 of the receiving die 21 will hinder the paper sheet 3 from entering the concave portion 211 , and the paper sheet 3 may not be able to completely enter the concave portion 211 solely by its own gravity.

[0160] The positioning mechanism 50 can push the paper sheet 3 along the first direction X, which is beneficial to reduce the risk of the paper sheet 3 being partially stuck outside the recess 211 and is beneficial for the receiving die 21 to accurately position the paper sheet 3 .

[0161] In some embodiments, the positioning mechanism 50 includes a support shaft 51 and a plurality of positioning members 52. The support shaft 51 extends along the second direction Y and is rotatably mounted on the upper side of the second end 412. The plurality of positioning members 52 are spaced apart along the second direction Y on the support shaft 51. Each positioning member 52 is disposed corresponding to a corresponding conveying channel 41. The positioning member 52 is fixedly mounted on the support shaft 51 to rotate synchronously with the support shaft 51. When the positioning member 52 rotates to a vertical state, the bottom of the positioning member 52 is lower than the bottom surface of the recess 211.

[0162] The support shaft 51 may be mounted to the support frame 45 . Optionally, the support shaft 51 may be rotatably supported by two support plates 452 of the support frame 45 .

[0163] The positioning mechanism 50 further includes a second driving mechanism, which is used to drive the support shaft 51 to rotate. The second driving mechanism can be mounted on the support plate 452.

[0164] The positioning member 52 may be integrally formed with the support shaft 51 , or may be connected by sleeve connection, snap connection, contour connection or other suitable means.

[0165] Driven by the support shaft 51 , the positioning member 52 can swing at least in the space above the second end 412 .

[0166] The portion of the positioning member 52 that is in contact with the sheet of paper 3 may be a sheet-like structure. The positioning member 52 can be in surface contact with the sheet of paper 3, which is beneficial to increase the contact area between the two and improve the pushing effect.

[0167] When the positioning member 52 is rotated to a vertical state, the bottom of the positioning member 52 is at the lowest position, and the bottom of the positioning member 52 is lower than the bottom surface of the recess 211, so that the positioning member 52 can contact the end surface of the sheet paper 3, thereby pushing the sheet paper 3 conveyed through a corresponding conveying channel 41 toward the recess 211 of a corresponding receiving mold position 21 through the positioning member 52.

[0168] In some embodiments, reference Fig.10 The conveying unit 40a includes a second stopper 44, which is arranged obliquely along the extending direction of the conveying passage 41, and the conveying passage 41 is located at the lower side of the second stopper 44. The positioning member 52 includes a first positioning portion 521 and a second positioning portion 522, which are respectively located at two sides of the second stopper 44 along the second direction Y, and the first positioning portion 521 and the second positioning portion 522 are separated by an avoidance notch 523, and the avoidance notch 523 extends to an end of the positioning member 52 away from the support shaft 51, and at least a part of the second stopper 44 is arranged in the avoidance notch 523.

[0169] Along the vertical direction Z, the projection of the second limiting member 44 is located within the projection of the conveying passage 41 , so as to limit the sheet of paper 3 in the conveying passage 41 in the vertical direction Z.

[0170] During the rotation of the positioning member 52 in the space above the second end 412, the positioning member 52 may interfere with the second position-limiting member 44. To this end, in the embodiment of the present application, an avoidance notch 523 is provided on the positioning member 52, and at least a portion of the second position-limiting member 44 is provided in the avoidance notch 523, which can reduce the risk of interference between the positioning member 52 and the second position-limiting member 44 during the rotation process.

[0171] The first positioning portion 521 and the second positioning portion 522 can push different positions of the paper sheet 3 along the second direction Y, which is beneficial to improving the force balance of the paper sheet 3 and reducing the risk of the paper sheet 3 being deflected and wrinkled due to the pushing action of the positioning member 52.

[0172] In some embodiments, reference Figure 2 The paper cutting device 1 further includes a plurality of unwinding mechanisms 61 arranged along the second direction Y. The plurality of unwinding mechanisms 61 are arranged in one-to-one correspondence with the plurality of conveying units 40 a. The unwinding mechanisms 61 are used to unwind the strip-shaped paper 2 .

[0173] The unwinding mechanism 51 may include an unwinding roller, and the strip-shaped paper material 2 is wound around the unwinding roller.

[0174] Optionally, the paper cutting device 1 further includes an unwinding shaft 62, and a plurality of unwinding mechanisms 61 can be sleeved outside the unwinding shaft 62 and spaced apart along the second direction Y. Each unwinding mechanism 61 is connected to the unwinding shaft 62 and fixed relative to the unwinding shaft 62 to rotate synchronously with the unwinding shaft 62.

[0175] The multiple unwinding mechanisms 61 rotate synchronously under the drive of the same unwinding shaft 62, so that the multiple unwinding mechanisms 61 unwind synchronously, and the cutting mechanism 30 cuts synchronously to form multiple sheets of paper 3, which is beneficial for the multiple conveying units 40a of the conveying mechanism 40 to convey multiple sheets of paper 3 synchronously.

[0176] Alternatively, the plurality of unwinding mechanisms 61 can be driven to unwind independently of each other. The plurality of unwinding mechanisms 61 can be controlled to unwind the strip-shaped paper material 2 synchronously, so that the cutting mechanism 30 synchronously cuts to form a plurality of sheet-shaped paper materials 3, thereby conveying the plurality of sheet-shaped paper materials 3 simultaneously through the plurality of conveying units 40a.

[0177] In the embodiment of the present application, multiple unwinding mechanisms 61 are used to unwind multiple strip-shaped paper materials 2 respectively, and the size of the strip-shaped paper material 2 along the second direction Y can be the same as the size of the sheet-shaped paper material 3 along the second direction Y, which is conducive to simplifying the structure of the cutting mechanism 30 and reducing the mutual influence between the multiple sheet-shaped paper materials 3. Exemplarily, the cutter 31 of the cutting mechanism 30 can cut the strip-shaped paper material 2, which is conducive to simplifying the structure of the cutter 31, and can also reduce the cutting end surface and improve the cutting effect.

[0178] In some embodiments, reference Figure 1 and Figure 2 The paper material cutting device 1 further includes at least one guide roller 71, which is arranged between the unwinding mechanism 61 and the cutting mechanism 30 along the running direction of the strip-shaped paper material 2. The strip-shaped paper material 2 can be wound around at least one guide roller 71 to facilitate tensioning of the strip-shaped paper material 2.

[0179] A plurality of limiting rings 72 are provided on the guide roller 71, and the limiting rings 72 protrude from the outer peripheral surface of the guide roller 71. Each strip of paper 2 passes between two adjacent limiting rings 72. The limiting rings 72 can limit the strip of paper 2 along the second direction Y, so that the position of the strip of paper 2 corresponds to the position of the conveying channel 41 one by one.

[0180] In some embodiments, reference Figure 1 The paper material cutting device 1 further comprises a paper material driving mechanism, which is arranged between the unwinding mechanism 61 and the cutting mechanism 30 along the running direction of the strip-shaped paper material 2. The paper material driving mechanism comprises two pressed driving rollers 80. The two driving rollers 80 are configured to rotate in opposite directions to drive the strip-shaped paper material 2 sandwiched between the two driving rollers 80 to move toward the cutting mechanism 30.

[0181] The two driving rollers 80 rotate in opposite directions. Along the first direction X, the two driving rollers 80 have the same rotation trend relative to the strip of paper 2 sandwiched between the two driving rollers 80 , and can drive the strip of paper 2 to move along the first direction X.

[0182] Optionally, the paper material driving mechanism may be disposed between the guide roller 71 and the cutting mechanism 30. The strip of paper material 2 passes between the two driving rollers 80, and the two driving rollers 80 can flatten the strip of paper material 2, which is beneficial to improving the flatness of the strip of paper material 2 and facilitating the cutting mechanism 30 to cut the strip of paper material 2.

[0183] The embodiment of the present application further provides a food packaging structure production device 4, and the food packaging structure production device 4 includes the paper cutting device 1 provided in any embodiment of the present application.

[0184] In some embodiments, the food packaging structure production equipment 4 also includes a material taking mechanism 5 and a hot pressing device 6. The material taking mechanism 5 is configured to take the sheet paper 3 from all the receiving mold positions 21 of the material receiving mechanism 20 at one time and transfer it to the hot pressing device 6.

[0185] The material picking mechanism 5 may include a robot frame and a material picking drive mechanism. The robot frame can move between the material receiving mechanism 20 and the hot pressing device 6 under the driving action of the material picking drive mechanism.

[0186] The material taking mechanism 5 can take the sheet-shaped paper material 3 by adsorption or other suitable means.
