[0046] like Figures 1 to 4 As shown, some embodiments of the present application provide a sandwich device, which is mainly used in the production of sandwich biscuits to improve production efficiency and reduce production costs.

[0047] The sandwich device includes a conveying assembly 100 , a guide member 200 , a positioning device 300 , a pushing device 400 and a lifting device 500 .

[0048] In this embodiment, the sandwich device has a first direction, a second direction and a third direction that are perpendicular to each other.

[0049] The conveying assembly 100 includes a plurality of conveyor belts 110 with the same transmission direction. The plurality of conveyor belts 110 are arranged at intervals, wherein the plurality of conveyor belts 110 are arranged at equal intervals along the second direction, and the transmission direction of the conveyor belts 110 is the first direction.

[0050] It should be noted that, in this embodiment, the conveyor belt 110 is used to convey the bottom cake. The conveyor belt 110 has a conveying surface. The bottom cake is placed on the conveying surface and is driven by the conveyor belt 110 to move along the first direction during the transmission process.

[0051] The guide member 200 is spaced apart from the conveyor belt 110 , specifically, is disposed on one side of the conveyor belt 110 along the third direction, and the guide member 200 is close to the conveying surface.

[0052] The guide member 200 is provided with a plurality of guide grooves 210 , and the plurality of guide grooves 210 are arranged at equal intervals along the second direction, so as to provide guidance and limiting functions for the cake cover through the guide grooves 210 .

[0053] It should be noted that, in this embodiment, the number of guide grooves 210 is equal to the number of conveyor belts 110, and each guide groove 210 corresponds to a conveyor belt 110, that is, in the projection along the third direction, the guide groove 210 is opposite to the conveyor belt 110, so that the cake cover placed in the guide groove 210 can be opposite to the bottom cake placed on the conveyor belt 110, to ensure that the cake cover can overlap with the bottom cake.

[0054] The positioning device 300 is provided between the guide member 200 and the conveying assembly 100 , so as to provide a positioning function for the cake cover through the positioning device 300 , thereby ensuring that the cake cover can be aligned with the bottom cake.

[0055] Among them, the positioning device 300 is provided with a plurality of mounting positions 310. It should be noted that the number of mounting positions 310 is equal to the number of guide grooves 210, and each of the mounting positions 310 corresponds to an outlet end 211 adjacent to one of the guide grooves 210, so that the cake cover placed in the guide groove 210 can be pushed to the mounting position 310 by the pushing device 400.

[0056] In this embodiment, the installation position 310 is opposite to the conveyor belt 110 in the transmission direction perpendicular to the conveyor belt 110, so that the cake cover pushed onto the installation position 310 can be opposite to the bottom cake on the conveyor belt 110, thereby ensuring the accuracy of the fit between the cake cover and the bottom cake, thereby improving production quality.

[0057] It should be noted that, in this embodiment, the installation position 310 has an open state and a closed state.

[0058] When the mounting position 310 is in a closed state, the cake cover placed in the guide groove 210 can be pushed to the mounting position 310 by the pushing device 400, and the mounting position 310 provides a limiting and supporting function for the cake cover to ensure the stability of the cake cover on the mounting position 310, and at the same time ensure the accuracy of the positioning of the cake cover.

[0059] When the mounting position 310 is in the open state, the cake cover can be moved to the top of the conveyor belt 110 by the lifting device 500 so that the cake cover and the bottom cake are accurately fitted.

[0060] The pushing device 400 is disposed on one side of the guide member 200 , and the pushing device 400 can push the cake cover placed in the guide groove 210 to the installation position 310 in a closed state.

[0061] The lifting device 500 is arranged on the side of the positioning device 300 away from the conveying component 100, so as to adsorb the cake cover through the lifting device 500 and drive the cake cover to move along the third direction so that the cake cover can pass through the installation position 310 and fit with the bottom cake placed on the conveyor belt 110.

[0062] In this embodiment, the lifting device 500 includes a driving structure 510 and a plurality of suction nozzles 520, and the plurality of suction nozzles 520 are arranged at equal intervals along the third direction. Each suction nozzle 520 is connected to the driving structure 510, and the number of suction nozzles 520 is equal to the number of mounting positions 310, and each suction nozzle 520 corresponds to an mounting position 310, that is, the suction nozzle 520 can adsorb the cake cover located on the corresponding mounting position 310.

[0063] Specifically, the driving structure 510 can drive the suction nozzle 520 to adsorb the cake cover on the mounting position 310 in a closed state, and control the suction nozzle 520 with the cake cover adsorbed to pass through the mounting position 310 in an open state through the driving structure 510, so that after the cake cover is fitted with the bottom cake on the conveyor belt 110, the cake cover is released through the suction nozzle 520, thereby completing the fitting between the cake cover and the bottom cake.

[0064] The cake cover placed in the guide groove 210 can be pushed to the installation position 310 through the pushing device 400, and the suction nozzle 520 is driven by the driving structure 510 to adsorb the cake cover on the installation position 310 and pass through the installation position 310 in the open state so that the cake cover fits with the bottom cake on the conveyor belt 110. This not only improves the production efficiency of sandwich biscuits, but also makes the installation position 310 adjacent to the outlet end 211 of the guide groove 210 and facing the conveyor belt 110 to ensure that the cake cover can face the bottom cake on the conveyor belt 110 when in the installation position 310, thereby improving the production quality of sandwich biscuits.

[0065] like Figure 1 As shown, in some embodiments of the present application, the pushing device 400 includes a plurality of first driving members 410, wherein the number of the first driving members 410 is equal to the number of the guide grooves 210, the plurality of first driving members 410 are arranged at equal intervals along the second direction, and one first driving member 410 is opposite to one guide groove 210 along the first direction.

[0066] In addition, a pusher 420 is provided at the output end of the first driving member 410. The pusher 420 may be a push rod or a push plate. It should be noted that the first driving member 410 can drive the pusher 420 through the guide member 200 and push the pancake cover placed in the guide slot 210 to the mounting position 310 via the end of the pusher 420 facing away from the first driving member 410.

[0067] It can be understood that the moving direction of the pushing member 420 is parallel to the first direction.

[0068] like Figure 3 、 Figure 4 and Figure 6 As shown, in some embodiments of the present application, the driving structure 510 includes an exhaust pipe 511 and at least one second driving member 512. It is understandable that the number of the second driving member 512 can be one, two, or more than two.

[0069] Wherein, along the first direction, one end of the exhaust pipe 511 is provided with a connecting port, and the connecting port is used to be connected to the air inlet end of the exhaust fan.

[0070] In addition, one end of the suction nozzle 520 is connected to the side of the exhaust pipe 511 facing the conveyor belt 110, and the other end of the suction nozzle 520 faces the conveyor belt 110, so that when the exhaust fan is running, negative pressure can be formed at the end of the suction nozzle 520 facing the conveyor belt 110, so that the cake cover located on the installation position 310 can be adsorbed on the suction nozzle 520 under the action of negative pressure.

[0071] It should be noted that the plurality of suction nozzles 520 are arranged at equal intervals along the axial direction of the exhaust pipe 511 , and the number of the suction nozzles 520 is equal to the number of the installation positions 310 .

[0072] In this embodiment, the output end of the second driving member 512 is connected to the side of the exhaust pipe 511 away from the conveyor belt 110 , so that the exhaust pipe 511 is driven to move along the third direction by the second driving member 512 .

[0073] It can be understood that when the second driving member 512 drives the exhaust pipe 511 to move toward the direction close to the installation position 310, when the suction nozzle 520 is in contact with the cake cover on the installation position 310, the exhaust fan is operated to allow the suction nozzle 520 to adsorb the cake cover on the installation position 310. At this time, the positioning device 300 controls the installation position 310 to be in an open state, and the second driving member 512 controls the suction nozzle 520 with the cake cover adsorbed to pass through the installation position 310 and move toward the direction close to the conveyor belt 110; when the cake cover is in contact with the bottom cake on the conveyor belt 110, the exhaust fan stops running, so that the cake cover is in contact with the bottom cake under the action of its own gravity. At the same time, the second driving member 512 drives the exhaust pipe 511 to move in a direction away from the conveyor belt 110, thereby driving the suction nozzle 520 to move synchronously, so that the lifting device 500 is reset to facilitate the movement of the next group of cake covers.

[0074] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the lifting device 500 further includes at least one third driving member 540. It can be understood that the number of the third driving member 540 can be one, two, or more than two.

[0075] The third driving member 540 is disposed on a side of the second driving member 512 facing away from the exhaust pipe 511. A first connecting plate 550 is disposed between the third driving member 540 and the second driving member 512. The side of the first connecting plate 550 facing the second driving member 512 is connected to the second driving member 512. The side of the first connecting plate 550 facing the third driving member 540 is connected to the output shaft of the third driving member 540, so that the output end of the third driving member 540 drives the first connecting plate 550 to move in the third direction, thereby driving the second driving member 512 to move in the third direction. Since the exhaust pipe and the nozzle are respectively connected to the second driving member 512, the exhaust pipe and the nozzle can be driven to move in the third direction by the third driving member 540, thereby adjusting the distance between the nozzle and the conveyor belt 110.

[0076] like Figure 3 and Figure 6 As shown, in some embodiments of the present application, the positioning device 300 includes a positioning plate 350 , a fourth driving member 320 , at least one transmission shaft 330 and a plurality of first limiting plates 340 .

[0077] It is understandable that the number of the transmission shafts 330 can be one, two, or any number above two, and can be specifically set according to actual conditions.

[0078] The positioning plate 350 is provided with a plurality of spaced limiting holes 351 , the number of the limiting holes 351 is equal to the number of the mounting positions 310 , and the plurality of limiting holes 351 are arranged at equal intervals along the second direction on the positioning plate 350 .

[0079] In addition, the fourth driving member 320 is arranged on one side of the positioning plate 350, and the transmission shaft 330 is arranged on the side of the positioning plate 350 facing the conveyor belt 110. The output shaft of the fourth driving member 320 is connected to the transmission shaft 330 to control the rotation direction of the transmission shaft 330 through the fourth driving member 320.

[0080] Multiple first limiting plates 340 are located on the side of the positioning plate 350 facing the conveyor belt 110. It should be noted that the number of first limiting plates 340 is equal to the number of limiting holes 351, and the first limiting plates 340 are transmission-connected to the transmission shaft 330, and multiple first limiting plates 340 are arranged along the axial direction of the transmission shaft 330.

[0081] It is understandable that the first limiting plate 340 cooperates with the limiting hole 351 to form the installation position 310 .

[0082] In this embodiment, a first limiting plate 340 corresponds to an adjacent limiting hole 351. When the fourth driving member 320 drives the transmission shaft 330 to rotate, the transmission shaft 330 can drive the first limiting plate 340 to close the limiting hole 351 or open the limiting hole 351, thereby controlling the installation position 310 to be in an open state or a closed state.

[0083] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the conveying assembly 100 includes a support frame 120 , a driving roller 130 and a driven roller 140 .

[0084] Among them, the active roller 130 and the driven roller 140 are arranged at intervals along the first direction, the active roller 130 and the driven roller 140 are respectively rotatably connected to the support frame 120, and the active roller 130 and the driven roller 140 are connected through the conveyor belt 110, that is, during the rotation of the active roller 130, the driven roller 140 can be driven to rotate synchronously through the conveyor belt 110, thereby driving the bottom cake placed on the conveying surface to move through the conveyor belt 110.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the sandwich device further includes an adjustment device 600 .

[0086] The adjusting device 600 comprises a sliding rail 610 and a first sliding block 620. The sliding rail 610 is arranged on one side of the support frame 120, and the first sliding block 620 is in sliding connection with the sliding rail 610, and the sliding direction of the first sliding block 620 is parallel to the first direction. Meanwhile, the first sliding block 620 is connected with the frame body 530, so that the first sliding block 620 can drive the frame body 530 to move synchronously during sliding on the sliding rail 610. Since the third driving device, the second driving device, the air suction pipe 511 and the nozzle are connected with the frame body 530 respectively, the third driving device, the second driving device, the air suction pipe 511 and the nozzle can be driven to move synchronously by the frame body 530, so that the nozzle can be opposite to the limiting hole 351, thereby ensuring the accuracy of the combination of the cake cover and the bottom cake and improving the production quality.

[0087] As shown in Figure 1 and Figure 5 In some embodiments of the present application, the guide 200 comprises a guide plate 220 and a plurality of spaced second limiting plates 230. The plurality of second limiting plates 230 are arranged equidistantly along a second direction on one side of the guide 200, so as to define the guide groove 210 between the side of the guide 200 facing the second limiting plates 230 and two adjacent limiting plates.

[0088] The guide groove 210 has a smooth groove and a horizontal groove. The smooth groove provides guiding and limiting functions for the cake cover, and the horizontal groove provides guiding function for the cake cover, so as to ensure that the pushing member can push the cake cover to move on the horizontal groove to the mounting position 310.

[0089] As shown in Figure 5 and Figure 6 In some embodiments of the present application, the guide plate 220 is provided with a guide hole 240 communicating with the guide groove 210 on the side facing the first driving member 410.

[0090] It should be noted that the guide hole 240 is arranged at the connecting end between the smooth groove and the horizontal groove. The number of guide holes 240 is equal to the number of guide grooves 210.

[0091] The end of the pushing member 420 away from the first driving member 410 can pass through the guide hole 240, and can push the cake cover placed in the guide groove 210 to the mounting position 310.

[0092] As shown in Figures 3 to 6As shown, in some embodiments of the present application, at least one guide rail 700 and at least one second slider 800 are provided on the side of the frame 530 facing the conveyor belt 110. It is understood that the number of guide rails 700 and second sliders 800 can be one, two, or more than two, respectively, and can be set according to actual conditions.

[0093] In addition, the second slider 800 is slidably connected to the guide rail 700, and the side of the second slider 800 facing away from the guide rail 700 is connected to the first connecting plate 550. The sliding direction of the second slider 800 on the guide rail 700 is parallel to the third direction, so that the guide rail 700 and the second slider 800 provide limiting and guiding functions for the second driving member 512, the third driving member 540, the exhaust pipe 511 and the nozzle, so as to improve the accuracy and stability of the nozzle during movement.

[0094] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.
