[0043] 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.

[0044] The paper cutting device of the embodiment of the present application is described below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 11 The paper cutting device 1 provided in the embodiment of the present application comprises a frame 10, a material receiving mechanism 20, a cutting mechanism 30 and a material transfer mechanism 40. The material receiving mechanism 20 is arranged on the frame 10, and the material receiving mechanism 20 comprises a plurality of material receiving molds 21 arranged in an array, and the material receiving molds 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 a plurality of sheet paper 3 matching the material receiving molds 21. The material transfer mechanism 40 includes a moving unit 41 and a plurality of suction units 42. The moving unit 41 is configured to be movably disposed on the frame 10 along a first direction X. The plurality of suction units 42 are disposed on the moving unit 41 and distributed along a second direction Y. The second direction Y is perpendicular to the first direction X. Along the first direction X, each suction unit 42 is disposed opposite to a corresponding row of receiving mold positions 21. The suction unit 42 is configured to suction the sheet paper 3 and release the sheet paper 3 after the moving unit 41 moves to the corresponding receiving mold position 21.

[0046] The strip-shaped paper material 2 may be a strip-shaped absorbent paper, silicone oil paper or other paper material structure.

[0047] The frame 10 is used to support the material receiving mechanism 20, the cutting mechanism 30, the material transfer mechanism 40 and other mechanisms that may be included in the paper material cutting device 1. The material receiving mechanism 20 may be fixedly mounted on the frame 10.

[0048] The receiving mechanism 20 has a plurality of receiving mold positions 21, each of which is used to receive the sheet paper 3 transferred by the transfer 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.

[0049] The cutting mechanism 30 can cut the strip-shaped paper material 2 into a plurality of sheet-shaped paper materials 3, and the plurality of sheet-shaped paper materials 3 are respectively arranged in one-to-one correspondence with the plurality of adsorption units 42. Moreover, 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-shaped paper materials 3 that match the splicing die position 21.

[0050] Optionally, there may be multiple strips of paper 2 distributed along the second direction Y, and the multiple strips of paper 2 are respectively arranged in one-to-one correspondence with the multiple adsorption units 42, and the cutting mechanism 30 can cut the multiple strips of paper 2 into multiple sheets of paper 3.

[0051] Alternatively, there may be one strip of paper material 2 , and the cutting mechanism 30 may cut the strip of paper material 2 into a plurality of sheet-shaped paper materials 3 distributed along the second direction Y.

[0052] The sheet paper 3 matches the splicing die 21 in that the shape of the sheet paper 3 is similar to that of the splicing die 21, the size of the sheet paper 3 is roughly equivalent to that of the splicing die 21, and after the splicing die 21 receives the sheet paper 3, the position of the sheet paper 3 relative to the splicing die 21 is fixed or not easy to change.

[0053] 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.

[0054] 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 .

[0055] The plurality of suction units 42 of the material transfer mechanism 40 are distributed along the second direction Y, and each suction unit 42 is disposed opposite to a corresponding row of receiving die positions 21. In other words, the number of suction units 42 is the same as the number of receiving die positions 21 in each row, that is, the number of suction units 42 is the same as the number of rows in which the receiving die positions 21 are distributed. Along the first direction X, each suction unit 42 can be disposed opposite to a corresponding row of receiving die positions 21, so as to facilitate conveying the sheet of paper 3 to the row of receiving die positions 21.

[0056] The moving unit 41 of the material transfer mechanism 40 can move bidirectionally relative to the frame 10 in the first direction X, thereby driving the multiple adsorption units 42 to move synchronously along the first direction X. When the moving unit 41 drives the multiple adsorption units 42 to move to a corresponding row of receiving mold positions 21, the multiple adsorption units 42 can release the sheet paper 3 to the multiple receiving mold positions 21 in the row, respectively, so as to transfer the sheet paper 3 to the receiving mechanism 20. After the multiple adsorption units 42 release the sheet paper 3, the moving unit 41 drives the multiple adsorption units 42 to move toward the cutting mechanism 30 along the first direction X, so as to adsorb and transfer the multiple sheet paper 3 cut by the cutting mechanism 30 again. This is repeated until each row of receiving mold positions 21 receives the sheet paper 3 and the receiving mechanism 20 is full of materials.

[0057] In order to facilitate the suction unit 42 to release the sheet paper 3 to the receiving mold position 21, the suction unit 42 can be located on the upper side of the receiving mechanism 20, and the moving unit 41 drives multiple suction units 42 to move on the upper side of the receiving mechanism 20, so that the multiple suction units 42 and the corresponding row of multiple receiving mold positions 21 are arranged one by one in the vertical direction, which is beneficial to improve the position accuracy of the sheet paper 3.

[0058] The moving unit 41 may include two vertical brackets 411 and a horizontal bracket 412, the two vertical brackets 411 are arranged opposite to each other along the second direction Y, and the horizontal bracket 412 is mounted on the top of the two vertical brackets 411. The horizontal bracket 412 is located at a position higher than the position of the material receiving mechanism 20. A plurality of adsorption units 42 are mounted on the horizontal bracket 412.

[0059] The adsorption unit 42 can selectively adsorb or release the sheet of paper 3. Optionally, the adsorption unit 42 can adsorb the sheet of paper 3 by vacuum adsorption or other suitable means, and can release the sheet of paper 3 after the adsorption effect of the adsorption unit 42 on the sheet of paper 3 is released.

[0060] The adsorption unit 42 may include a plurality of suction cups, and the plurality of suction cups may be arranged along a first direction X, or along a second direction Y, or in an array to improve adsorption stability.

[0061] The material transfer mechanism 40 may further include a first driving unit 43 , which is connected to the moving unit 41 and is used to drive the moving unit 41 to move along the first direction X. Optionally, the first driving unit 43 may be connected to two vertical brackets 411 .

[0062] The paper cutting device 1 may further include a guide rail 44 extending along the first direction X, the vertical bracket 411 is slidably connected to the guide rail 44, and the guide rail 44 is used to guide the moving unit 41 to move straightly along the first direction X.

[0063] The paper cutting device 1 of the embodiment of the present application includes a material receiving mechanism 20 and a material transfer mechanism 40. The moving unit 41 of the material transfer mechanism 40 can drive multiple adsorption units 42 distributed along the second direction Y to move along the first direction X, thereby conveying sheet paper 3 to multiple material receiving mold positions 21 arranged in an array of the material receiving mechanism 20. The material receiving mechanism 20 can simultaneously accommodate multiple sheet paper materials 3, which is convenient for loading multiple sheet paper materials 3 at one time to the production device located downstream of the paper cutting device 1 through the material receiving mechanism 20, which is conducive to realizing automatic loading, improving the production efficiency of paper products, and reducing production safety hazards.

[0064] 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 loading, improving the production quality rate of paper products, and improving the product appearance.

[0065] In some embodiments, the adsorption unit 42 is configured to be movably disposed relative to the frame 10 along the vertical direction Z, and the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other.

[0066] The material transfer mechanism 40 may further include a second driving unit, which is directly or indirectly connected to the adsorption unit 42 and is used to drive the adsorption unit 42 to move along the vertical direction Z. The second driving unit may be disposed on a transverse bracket 412 of the moving unit 41 .

[0067] The second driving unit may be a cylinder telescopic mechanism, a gear rack mechanism, a worm gear mechanism or other suitable driving mechanisms.

[0068] The suction unit 42 is movably arranged along the vertical direction Z, which is convenient for the suction unit 42 to suction the sheet paper 3, and also convenient for the suction unit 42 to release the sheet paper 3 after approaching the receiving die position 21, which is conducive to improving the position accuracy of the sheet paper 3 on the receiving die position 21, and further improving the position accuracy of the sheet paper 3 after feeding. In addition, when the moving unit 41 drives the suction unit 42 to move along the first direction X, the suction unit 42 can move up to a certain height, which is conducive to reducing the interference between the suction unit 42 and other structures.

[0069] In some embodiments, reference Figure 3 and Figure 4 The receiving mold position 21 includes a suction cup 211, and the suction cup 211 is used for sucking the sheet paper 3.

[0070] There may be a plurality of suction cups 211. The plurality of suction cups may be arranged along the first direction X, or along the second direction Y, or in an array to improve adsorption stability.

[0071] The plurality of suction cups 211 may be evenly distributed to produce a more balanced adsorption effect on the sheet of paper 3 , thereby reducing the phenomenon that the sheet of paper 3 is lifted up due to uneven force.

[0072] The suction cup 211 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 .

[0073] In some embodiments, reference Figure 3 and Figure 4 The receiving mold 21 further includes a receiving portion 212, a recess 213 is formed on the upper side of the receiving portion 212, and the suction cup 211 is disposed in the recess 213. Along the vertical direction Z, the first upper surface 212a of the receiving portion 212 is flush with the second upper surface 211a of the suction cup 211.

[0074] The recessed portion 213 is recessed downwardly from the first upper surface 212 a of the receiving portion 212 .

[0075] The suction cup 211 can be entirely accommodated in the recess 213 , and along the vertically upward direction, the suction cup 211 does not exceed the first upper surface 212 a of the material receiving portion 212 .

[0076] The first upper surface 212a of the material receiving portion 212 is flush with the second upper surface 211a of the suction cup 211, and the upper surface of the material receiving mold position 21 is in the same horizontal plane as a whole. The size of the sheet paper 3 can match the projection size of the recess 213, and can also match the projection size of the entire material receiving portion 212. The material receiving mechanism 20 can receive sheet paper 3 of various sizes, which is conducive to expanding the application range of the material receiving mechanism 20 and improving its adaptability. In addition, it is also conducive to improving the flatness of the sheet paper 3 and reducing the risk of wrinkles or creases on the sheet paper 3.

[0077] The receiving mold 21 provided in the embodiment of the present application forms a recess 213 on the receiving portion 212 to accommodate the suction cup 211, and absorbs the sheet paper 3 through the suction cup 211. The structure is simple, which is beneficial to reducing design costs, reducing the failure rate of the receiving process, and improving the reliability of the paper cutting device 1.

[0078] In some embodiments, reference Figure 1 and Figure 5 The paper cutting device 1 further includes a plurality of unwinding units 51 arranged along the second direction Y. Along the first direction X, the plurality of unwinding units 51 are arranged in one-to-one correspondence with the plurality of adsorption units 42 . The unwinding units 51 are used to unwind the strip-shaped paper 2 .

[0079] The unwinding unit 51 may include an unwinding roller, and the strip-shaped paper material 2 is wound around the unwinding roller.

[0080] Optionally, the paper material cutting device 1 further includes an unwinding shaft 52, and a plurality of unwinding units 51 can be sleeved outside the unwinding shaft 52 and spaced apart along the second direction Y. Each unwinding unit 51 is connected to the unwinding shaft 52 and fixedly arranged relative to the unwinding shaft 52 so as to rotate synchronously with the unwinding shaft 52. The unwinding shaft 52 and the plurality of unwinding units 51 together form an unwinding mechanism 50.

[0081] The multiple unwinding units 51 rotate synchronously under the drive of the same unwinding shaft 52, so that the multiple unwinding units 51 unwind synchronously, and the cutting mechanism 30 cuts synchronously to form multiple sheets of paper 3, which is beneficial for the multiple adsorption units 42 of the material transfer mechanism 40 to synchronously adsorb and transfer the multiple sheets of paper 3.

[0082] Alternatively, the plurality of unwinding units 51 may be driven to unwind independently of each other. The plurality of unwinding units 51 may be controlled to unwind the strip-shaped paper material 2 synchronously, so that the cutting mechanism 30 synchronously cuts and forms a plurality of sheet-shaped paper materials 3 .

[0083] In the embodiment of the present application, a plurality of unwinding units 51 are used to unwind a plurality of strip-shaped paper materials 2, 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 plurality of sheet-shaped paper materials 3. Exemplarily, the cutter of the cutting mechanism 30 can cut the strip-shaped paper material 2, which is conducive to simplifying the structure of the cutter, and can also reduce the cutting end surface and improve the cutting effect.

[0084] In some embodiments, reference Figure 7 and Figure 8 The cutting mechanism 30 may include a plurality of cutters 31. Along the first direction X, the plurality of cutters 31 are respectively arranged in one-to-one correspondence with the plurality of unwinding units 51. The plurality of cutters 31 are respectively used to cut the strip-shaped paper material 2 unwound by the plurality of unwinding units 51, so as to facilitate the independent maintenance of each cutter 31 and reduce the maintenance cost.

[0085] The cutting mechanism 30 may further include a support plate 32, a cutting drive assembly 34 and a support frame 35, a plurality of cutters 31 are mounted on the support plate 32, and the cutting drive assembly 34 is directly or indirectly connected to the support plate 32, and is used to drive the support plate 32 to move along the vertical direction Z, so as to drive the plurality of cutters 31 to move along the vertical direction Z, thereby realizing the cutting function. The support plate 32 and the cutting drive assembly 34 are both mounted on the support frame 35, and the support frame 35 is supported by the frame 10.

[0086] The multiple cutters 31 are disposed on the same support plate 32 , which is beneficial for the multiple cutters 31 to cut the multiple strip-shaped paper materials 2 synchronously.

[0087] The cutter 31 is provided with a first connection hole 311, and the support plate 32 is provided with a second connection hole 321. The cutter 31 is connected to the support plate 32 by fasteners (such as screws) penetrating the first connection hole 311 and the second connection hole 321. The first connection hole 311 is an elongated hole extending along the second direction Y, which is conducive to adjusting the position of the cutter 31 relative to the support plate 32 in the second direction Y, so that the position of the cutter 31 matches the position of the strip-shaped paper material 2.

[0088] In some embodiments, reference Figure 1 and Figure 5 The frame 10 includes a support platform 11, and the material receiving mechanism 20, the cutting mechanism 30 and the material transfer mechanism 40 are all supported on the support platform 11. An accommodation space 12 is formed inside the frame 10, and the accommodation space 12 is located at the lower side of the support platform 11, and a plurality of unwinding units 51 are accommodated in the accommodation space 12.

[0089] The material receiving mechanism 20 may be fixedly disposed on the upper side of the supporting platform 11 .

[0090] The cutting mechanism 30 , the suction unit 42 , and at least part of the moving unit 41 may be disposed on the upper side of the supporting platform 11 . The first driving unit 43 and the guide rail 44 of the material transfer mechanism 40 may be disposed on the lower side of the supporting platform 11 and in the receiving space 12 .

[0091] The plurality of unwinding units 51 are located in the accommodating space 12 , which can improve space utilization and structural integration, reduce the volume of the paper cutting device 1 , and facilitate miniaturization of the paper cutting device 1 .

[0092] In some embodiments, reference Figure 7 and Figure 8 The cutting mechanism 30 includes a cutter 31 and a plurality of first limiting components 33. The plurality of first limiting components 33 are arranged one by one corresponding to the plurality of unwinding units 51 along the first direction X. The first limiting components 33 are located upstream of the cutter 31 along the running direction of the strip-shaped paper material 2. The first limiting components 33 are used to limit the strip-shaped paper material 2 along the second direction Y.

[0093] The first limiting assembly 33 may be located adjacent to and upstream of the cutter 31 , and no other process is provided between the first limiting assembly 33 and the cutter 31 .

[0094] There can be multiple cutters 31 , and the multiple cutters 31 are arranged in a one-to-one correspondence with the multiple first limiting components 33 .

[0095] In the embodiment of the present application, a first limiting component 33 is provided upstream of the cutter 31. The first limiting component 33 can limit the strip of paper 2 to be conveyed to the cutter 31 along the second direction Y, so that the position of the strip of paper 2 along the first direction X corresponds to the position of the downstream cutter 31, the adsorption unit 42, the splicing die 21, etc., which can reduce the possibility of position deviation between the sheet of paper 3 and the cutter 31, the adsorption unit 42 and the splicing die 21 due to the position deviation of the strip of paper 2, which is beneficial to reduce the risk of the strip of paper 2 not being effectively cut, and improve the position accuracy of the sheet of paper 3 relative to the splicing die 21, as well as the position accuracy of the sheet of paper 3 after loading.

[0096] In some embodiments, reference Fig. 9 and Fig.10 The first limiting assembly 33 defines a guide channel 331 inside, and the guide channel 331 penetrates the first limiting assembly 33 along the first direction X. The size and / or position of the guide channel 331 along the second direction Y are adjustable.

[0097] The guide channel 331 may be a circumferentially closed cylindrical channel, or a circumferentially semi-open hollow channel.

[0098] The cross section of the guide channel 331 may be flat, and the cross section shape of the guide channel 331 matches the cross section shape of the strip-shaped paper material 2 , which is beneficial for better positioning of the strip-shaped paper material 2 .

[0099] The size of the guide channel 331 along the second direction Y is adjustable. The guide channel 331 can allow a variety of strip-shaped paper materials 2 with different sizes along the second direction Y to pass therethrough, which is beneficial to improving its adaptability.

[0100] The position of the guide channel 331 along the second direction Y is adjustable. The position deviation of the strip of paper 2 relative to the cutter 31 can be adjusted by changing the position of the guide channel 331, which is beneficial to improving the position accuracy of the sheet of paper 3 formed after the cutter 31 cuts the strip of paper 2 relative to the material transfer mechanism 40 and the material receiving mechanism 20.

[0101] In some embodiments, reference Fig. 9 and Fig.10 The first stopper assembly 33 includes a base plate 332, and a first stopper 333 and a second stopper 334 located on the upper side of the base plate 332. The first stopper 333 and the second stopper 334 are both detachably connected to the base plate 332. The first stopper 333 and the second stopper 334 are spaced apart along the second direction Y. The guide channel 331 is formed between the first stopper 333, the second stopper 334 and the base plate 332. In other words, the first stopper 333, the second stopper 334 and the base plate 332 can enclose and form the guide channel 331.

[0102] The base plate 332 is used to support the first stopper 333 and the second stopper 334. The base plate 332 can be installed on the support frame 35.

[0103] The first limiting member 333 and the second limiting member 334 can be detachably connected to the base plate 332 by screw connection, clamping or other suitable methods.

[0104] Along the second direction Y, the position of the first stopper 333 relative to the base plate 332 can be independently adjusted, and the position of the second stopper 334 relative to the base plate 332 can be independently adjusted. The size and position of the guide channel 331 can be adjusted on both sides in the second direction Y by the first stopper 333 and the second stopper 334, which is conducive to improving the flexibility of adjusting the size and position of the guide channel 331, thereby meeting the needs of various different situations.

[0105] The first limit member 333 and the second limit member 334 are spaced apart along the second direction Y, and an adjustable space can be reserved between the first limit member 333 and the second limit member 334. The first limit member 333 and / or the second limit member 334 can be adjusted in a direction that makes the first limit member 333 and the second limit member 334 approach each other, thereby meeting the limiting requirements under certain working conditions.

[0106] In some embodiments, reference Fig. 9 and Fig.10 A guide groove 3321 is provided on the upper side of the substrate 332, and the guide groove 3321 extends along the second direction Y. The first limit member 333 and the second limit member 334 are both supported on the bottom surface of the guide groove 3321, and the dimensions of the first limit member 333 and the second limit member 334 along the first direction X match the dimensions of the guide groove 3321 along the first direction X.

[0107] The bottoms of the first limiting member 333 and the second limiting member 334 are both accommodated in the guiding groove 3321 .

[0108] Along the first direction X, the size of the first position-limiting member 333 matches the size of the guide groove 3321 , which means that the size of the first position-limiting member 333 may be equal to or slightly smaller than the size of the guide groove 3321 .

[0109] Along the first direction X, the size of the second position-limiting member 334 matches the size of the guide groove 3321 , which means that the size of the second position-limiting member 334 may be equal to or slightly smaller than the size of the guide groove 3321 .

[0110] When adjusting the position of the first limit member 333 and / or the second limit member 334, the first limit member 333 and / or the second limit member 334 can be moved along the guide groove 3321 to reduce the possibility of the first limit member 333 and / or the second limit member 334 being displaced along the first direction X, which is beneficial for the first limit member 333 and the second limit member 334 to remain flush and improve the smoothness of the strip paper 2 entering the guide channel 331.

[0111] In some embodiments, along the running direction of the strip of paper 2, the upstream end surface 3322 of the substrate 332 is an arc-shaped surface, which can guide the strip of paper 2 to the upper side of the substrate 332, thereby reducing the obstruction that the end surface 3322 may have on the strip of paper 2, and facilitating the smooth movement of the strip of paper 2.

[0112] In some embodiments, reference Figure 6 The paper material cutting device 1 further comprises a support platform 60. The cutter 31 is arranged between the support platform 60 and the first stop assembly 33 along the running direction of the strip-shaped paper material 2. The support platform 60 is used to support the sheet-shaped paper material 3 formed by cutting the strip-shaped paper material 2 by the cutting mechanism 30. The support platform 60 is provided with a plurality of marking portions 61. The plurality of marking portions 61 are arranged at equal intervals along the second direction Y. The dimensions of the marking portions 61 along the second direction Y are the same.

[0113] The support platform 60 is disposed adjacently to the downstream of the cutting mechanism 30. No other process is disposed between the support platform 60 and the cutting mechanism 30. The suction unit 42 can suction the sheet of paper 3 from the support platform 60.

[0114] The identification portion 61 may be any structure that can play an identification role.

[0115] Optionally, the identification portion 61 may be a slot extending along the first direction X, and a plurality of slots are arranged at equal intervals along the second direction Y, and the widths of the plurality of slots are the same. By arranging a slot on the upper side of the carrier 60 to form the identification portion 61, the portion corresponding to the slot is hollowed out and will not contact the sheet paper 3, which is conducive to reducing the contact area between the carrier 60 and the sheet paper 3, reducing the possibility of the sheet paper 3 adhering to the surface of the carrier 60, and facilitating the adsorption unit 42 to reliably adsorb the sheet paper 3.

[0116] Alternatively, the marking portion 61 may also be a scale line provided on the surface of the supporting platform 60 .

[0117] The support platform 60 can support the sheet of paper 3, so that the sheet of paper 3 is adsorbed by the adsorption unit 42 in a stable static state, which is conducive to improving the adsorption stability and adsorption effect. The marking portion 61 of the support platform 60 can provide a reference basis for the position adjustment amount of the cutter 31, the first limit assembly 33 and other structures along the second direction Y, which is conducive to improving the accuracy and consistency of the position adjustment.

[0118] In some embodiments, reference Figure 6 The paper material cutting device 1 further comprises a guide mechanism 70, which is arranged between the unwinding unit 51 and the cutting mechanism 30 along the running direction of the strip-shaped paper material 2. The guide mechanism 70 comprises a guide roller 71 and a plurality of second limit assemblies 72, and the plurality of second limit assemblies 72 are arranged one-to-one with the plurality of unwinding units 51 along the first direction X. The second limit assemblies 72 comprise two limit rings 721 arranged at intervals along the second direction Y, the limit rings 721 are sleeved on the outside of the guide roller 71 and protrude from the outer peripheral surface of the guide roller 71, and the portion of the guide roller 71 between the two limit rings 721 is used to wind the strip-shaped paper material 2.

[0119] The number of the guide mechanism 70 may be one or more.

[0120] The limiting ring 721 is detachably connected to the guide roller 71 so that the position of the limiting ring 721 in the second direction Y is adjustable, which is beneficial to changing the position of the limiting ring 721 relative to the guide roller 71 and the distance between the two limiting rings 721, thereby improving adaptability.

[0121] The guide mechanism 70 can tension the strip of paper 2 and change the running direction of the strip of paper 2 , thereby guiding the strip of paper 2 unwound by the unwinding unit 51 at the lower side of the support platform 11 to the mechanisms at the upper side of the support platform 11 .

[0122] The number of second limiting components 72 and unwinding units 51 is the same. Each second limiting component 72 can guide and limit the strip paper 2 unwound by the corresponding unwinding unit 51 in the second direction Y, so as to control the position accuracy of each mechanism downstream of the guide mechanism 70.

[0123] In some embodiments, reference Figure 6 and Fig.11 The paper material cutting device 1 further includes a paper material driving mechanism 80, which is disposed between the unwinding unit 51 and the cutting mechanism 30 along the running direction of the strip-shaped paper material 2. The paper material driving mechanism 80 includes a first driving roller 81 and a plurality of second driving rollers 82 distributed along the second direction Y. Along the first direction X, the plurality of second driving rollers 82 are disposed one-to-one with the plurality of unwinding units 51, the second driving rollers 82 are pressed against the first driving rollers 81, and the first driving rollers 81 and the second driving rollers 82 are configured to rotate in opposite directions to drive the strip-shaped paper material 2 sandwiched between the first driving rollers 81 and the second driving rollers 82 to move toward the cutting mechanism 30.

[0124] The first driving roller 81 and the second driving roller 82 rotate in opposite directions. Along the first direction X, the first driving roller 81 and the second driving roller 82 have the same rotation trend relative to the strip of paper 2 clamped between the first driving roller 81 and the second driving roller 82, and can drive the strip of paper 2 to move along the first direction X.

[0125] Optionally, the first driving roller 81 may rotate in a counterclockwise direction, and the second driving roller 82 may rotate in a clockwise direction.

[0126] The first driving roller 81 and the plurality of second driving rollers 82 are combined to form a plurality of paper tape driving units, each of which is used to drive a corresponding strip of paper material 2 to move. Thus, it is convenient to control the plurality of strips of paper material 2 to travel at the same speed, which is beneficial for the cutting mechanism 30 to synchronously cut and form a plurality of sheet paper materials 3.

[0127] The plurality of second driving rollers 82 cooperate with the first driving roller 81 respectively, which is beneficial to reducing the volume of a single second driving roller 82, simplifying the structure of the paper cutting device 1, facilitating maintenance, and reducing maintenance costs.

[0128] In some embodiments, reference Figure 1 and Figure 5 There are two cutting mechanisms 30 and two material transfer mechanisms 40. The two cutting mechanisms 30 are respectively located on both sides of the material receiving mechanism 20 along the first direction X. The two material transfer mechanisms 40 are respectively used to transfer the sheet paper 3 cut by the two cutting mechanisms 30 to the material receiving mold positions 21 in different rows.

[0129] Correspondingly, the number of the unwinding mechanism 50, the carrying platform 60 and the guiding mechanism 70 is also two. The two unwinding mechanisms 50 are arranged at intervals in the accommodating space 12 along the first direction X. The two carrying platforms 60 are respectively located on both sides of the receiving mechanism 20 along the first direction X, and each cutting mechanism 30 is arranged between a corresponding carrying platform 60 and the receiving mechanism 20. The two material transfer mechanisms 40 are arranged along the first direction X, and the moving paths of the moving units 41 of the two material transfer mechanisms 40 along the first direction X do not overlap to reduce interference.

[0130] The two unwinding mechanisms 50 can be independently arranged to unwind the strip-shaped paper material 2 independently, and the two unwinding mechanisms 50 can also be driven by the same driving mechanism to unwind the strip-shaped paper material 2 synchronously.

[0131] The multiple receiving mold positions 21 of the receiving mechanism 20 can be arranged into m rows along the first direction X, one of the material transfer mechanisms 40 can transfer the sheet paper 3 cut by a corresponding cutting mechanism 30 to the n-row receiving mold positions 21 close to one side of the cutting mechanism 30, where n is less than m; the other material transfer mechanism 40 can transfer the sheet paper 3 cut by another corresponding cutting mechanism 30 to the mn-row receiving mold positions 21 close to one side of the other cutting mechanism 30.

[0132] Optionally, m may be an even number, and the two cutting mechanisms 30 may synchronously perform cutting operations, and the two material transfer mechanisms 40 may synchronously perform material transfer operations, which is beneficial to saving time and improving efficiency.

[0133] In the embodiment of the present application, two cutting mechanisms 30 and two material transfer mechanisms 40 are provided. The two cutting mechanisms 30 can respectively perform cutting operations on different strip-shaped paper materials 2, and the two material transfer mechanisms 40 can respectively perform material transfer operations on different multiple sheet-shaped paper materials 3, which is beneficial to saving the time of filling the material receiving mechanism 20 with materials and improving efficiency.

[0135] 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.

[0136] 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.

[0137] The material taking mechanism 5 can take the sheet-shaped paper material 3 by adsorption or other suitable means.

[0138] The hot pressing device 6 is used to press the sheet paper material 3 onto the packaging base, which may be in a box shape, a belt shape or other suitable shapes.

[0139] The material taking mechanism 5 can feed a plurality of sheet paper materials 3 to the hot pressing device 6 at one time, which is conducive to realizing automatic feeding, improving the production efficiency of the food packaging structure, and reducing production safety hazards. In addition, the material taking mechanism 5 takes the material from the receiving mechanism 20, which is conducive to realizing the uniform position of the plurality of sheet paper materials 3, and is conducive to improving the position accuracy of the sheet paper materials 3 on the hot pressing device 6, improving the production rate of the food packaging structure, and improving the appearance of the food packaging structure.
