Detailed Implementation

[0021] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The following description, in conjunction with the accompanying drawings, describes a cake packaging box and its production and packaging apparatus according to embodiments of this application.

[0023] The cake packaging box provided in the embodiments of this application, such as Figures 1-3 As shown, it may include: The outer box 1 includes a box body 101, a box lid 102, and a front edge 103. The box body 101 has an opening. The box lid 102 is located on the side wall of the box body 101 away from the opening. The bottom surface of the box lid 102 is provided with a frame wall 104. The inner wall size of the frame wall 104 is adapted to the outer wall size of the box body 101. The front edge 103 is located at the bottom edge of the opening of the box body 101. A connecting wall strip 105 is provided between the front edge 103 and the opening. The outer box 1 serves as the external protective structure of the entire cake box, accommodating the inner box 2 and protecting the cake. The lid 102 is located on the side wall of the box body 101 away from the opening of the box body 101. The bottom surface of the lid 102 is provided with a frame wall 104. The inner wall size of the frame wall 104 is adapted to the outer wall size of the box body 101, so that when the lid 102 is closed, it can be tightly fastened to the box body 101, providing good sealing and protection.

[0024] The front edge 103 of the box is located at the bottom edge of the opening of the box body 101, and a connecting wall strip 105 is provided between the front edge 103 of the box and the opening.

[0025] The outer box 1 has an opening at the front. When the cake needs to be cut, the opening of the outer box 1 creates a space that allows a knife to easily enter, so that the square cake can be easily cut inside the box 101. People can directly cut the cake into suitable small pieces inside the outer box 1 without removing the cake, which is both convenient and keeps the cake hygienic.

[0026] The inner box 2 includes a base plate 201 and four sets of side panels 202, which are respectively connected to the four side walls of the base plate 201. The inner box 2 is placed inside the outer box 1. The inner box 2 is mainly used to hold the cake. The four sets of side panels 202 are respectively connected to the four side walls of the base plate 201, forming a space for holding the cake. The size design of the inner box 2 allows it to fit perfectly inside the outer box 1, providing the cake with a relatively independent storage space and further protecting the cake from external influences during transportation and sales.

[0027] The anti-inward tilting structure 3 includes side blocks 301, pull straps 302, and belt blocks 303. A set of side blocks 301 is fixed to the outer wall of each side plate 202. Four sets of belt blocks 303 are provided at the bottom of the bottom plate 201. Each set of side blocks 301 is connected to a pull strap 302, and each set of pull straps 302 is slidably connected inside the belt block 303. A stop block 304 is provided at the end of each pull strap 302. When the inner box 2 is placed in the outer box 1, pulling the pull strap 302 causes it to be pulled out of the belt block 303, tightening and fixing the side plate 202 and the bottom plate 201. Due to the presence of the stop block 304, the pull strap 302 will not completely detach from the belt block 303. In this way, even if the cake is bumped or shaken during transportation, the side panel 202 of the inner box 2 will not flip inward, thus ensuring the stability and integrity of the cake.

[0028] The stand 4 has a cake placement slot 401 on its top surface. The stand 4 is used to hold the cake, making it more stable during transportation and sales. Placing the cake in the cake placement slot 401 on the stand 4 ensures greater stability during transport and sales. The shape and size of the cake placement slot 401 are adapted to square cakes, effectively limiting cake movement. Simultaneously, the stand 4 can be placed inside the inner box 2, further enhancing the stability of the cake placement.

[0029] Specifically, during packaging, the inner box 2 is placed inside the outer box 1. After placing the cake in the cake placement slot 401 of the tray 4, the tray 4 is placed into the inner box 2. Then, the pull strap 302 connected to the side block 301 of the side plate 202 in the anti-tipping structure 3 is pulled out from the strap block 303 at the bottom of the bottom plate 201, and the side plate 202 and the bottom plate 201 are tightened and fixed. Then, the box lid 102 is tightly fastened to the box body 101 through the frame wall 104 on the bottom surface. This ensures that the cake does not shake during transportation and sales, the inner box 2 does not tip over, and the cake can be easily cut inside the outer box 1, while maintaining good sealing and hygiene conditions.

[0030] In one embodiment of this application, such as Figure 1 As shown, the height of the side panel 202 is 2-5 cm higher than the height of the cake packaged in the inner box 2.

[0031] Specifically, this design offers several advantages. Firstly, the higher side panel 202 creates a buffer space above the cake, preventing damage to the cake's decorations or shape due to pressure from above during transport. For example, even if the outer box 1 experiences some pressure during bumpy roads, the cake's top won't directly contact the top of the outer box 1 because the side panel 202 is higher than the cake, thus providing effective protection. Secondly, the higher side panel 202 also better secures the cake, preventing it from wobbling horizontally and further ensuring its integrity.

[0032] In one embodiment of this application, such as Figure 3 As shown, when the stop block 304 contacts the belt block 303, the angle between the side plate 202 and the bottom plate 201 is equal to or greater than 90 degrees.

[0033] Specifically, this design ensures the structural stability of the inner box 2. Even if subjected to significant bumps or shaking during transportation, the side panel 202 will not fold inward, thus effectively protecting the cake placed inside the inner box 2. For example, during long-distance transportation, the vehicle may pass through sections with poor road conditions, generating severe vibrations. However, due to the anti-folding structure 3, the inner box 2 remains stable, and the cake will not be damaged due to deformation of the inner box 2.

[0034] like Figures 4-11 As shown, a cake production and packaging device, Includes: a tray conveyor 5, which uses a motor-driven conveyor roller to transport the tray 4 along a predetermined track. The tray conveyor 5 is used to transport the tray 4. The tray conveyor 5 is equipped with a photoelectric switch. When the photoelectric switch senses the tray 4, the tray conveyor 5 stops, the conveying device 7 moves to the position of the tray conveyor 5, and then the tray 4 is moved away.

[0035] The inner box conveying device 6 is located on one side of the tray conveying device 5. The inner box conveying device 6 places the inner box 2 on the platform, and then the conveying device 7 places the cake and the tray 4 on the inner box 2.

[0036] The conveying device 7 is located in front of the discharge port of the tray conveyor 5. The conveying device 7 includes a conveying lifting platform 701, a conveying linear module 702, two sets of conveying telescopic rods 703, and two sets of conveying frames 704. The conveying device 7 is used to move the cake tray 4 onto the inner box conveyor 6, so that the tray 4 is placed on the inner box 2, and then the inner box 2 is placed inside the outer box 1.

[0037] The outer box conveying device 8 is located on the side of the inner box conveying device 6 away from the tray conveying device 5. The outer box motor drives the outer box conveying roller to rotate, and conveys the outer box 1 along the outer box conveying frame 801.

[0038] The packaging device is mounted on the outer box conveying device 8 and includes a horizontal folding block 901, a side folding mechanism 902, and a lid-closing device 903. The horizontal folding block 901 is used to fold the rear side panel 202 of the inner box 2 upwards, the side folding mechanism 902 is used to fold the side panels 202 of the inner box 2 upwards, and the lid-closing mechanism 903 is used to close the lid 102 of the outer box 1.

[0039] Specifically, the tray conveyor 5 uses a motor to drive the conveyor roller to convey the tray 4 along a predetermined track. When the photoelectric switch senses the tray 4, it stops. The conveyor 7 moves to the position and removes the tray 4. The inner box conveyor 6, located on one side of the tray conveyor 5, places the inner box 2 on the platform. The conveyor 7 then places the cake and the tray 4 on the inner box 2. After that, the inner box 2 is placed into the outer box 1, which is conveyed by the outer box conveyor roller driven by the outer box motor along the outer box conveyor frame 801. The outer box 1 is conveyed to the packaging device. The horizontal folding block 901 in the packaging device folds up the rear side panel 202 of the inner box 2. The side folding mechanism 902 folds up the two side panels 202 of the inner box 2. The lid mechanism 9032 closes the lid 102 of the outer box 1 to complete the packaging.

[0040] As another feature of this embodiment, such as Figure 4 As shown, the distance between the pallet conveyor 5 and the inner box conveyor 6 is the same as the distance between the inner box conveyor 6 and the outer box conveyor 8. This design ensures that while the pallet conveyor 7 is carrying the pallet, another pallet conveyor 7 is simultaneously packaging the next station.

[0041] In one embodiment of this application, such as Figures 4-9 As shown, the outer box conveying device 8 includes an outer box conveying frame 801, several sets of outer box conveying rollers and an outer box motor. A horizontal folding block 901 is fixed on the surface of the outer box conveying frame 801, and one side of the horizontal folding block 901 is an inclined side.

[0042] During the process of moving the inner box 2 to the outer box conveying device 8, one side plate 202 of the inner box 2 contacts the inclined edge, the side folds up, and then the lifting platform descends, causing the inner box 2 to fall into the interior of the outer box 1.

[0043] It should be noted that multiple sets of photoelectric sensors are installed at the position of the outer box 1 conveyor belt. When the outer box 1 just touches the photoelectric sensor, the outer box conveyor 8 stops, so that the position of the back of the outer box 1 is perpendicular to the horizontal folding block 901, ensuring that the side edge of the inner box 2 is folded smoothly.

[0044] like Figure 5 , Figure 9As shown, the side-folding mechanism 902 includes two sets of side-folding blocks 9021. The two sets of side-folding blocks 9021 are connected by a shaft. The shaft is rotatably connected inside one of the conveying frames 704. A first gear 9022 is fixed on the outer wall of the shaft. A side-folding motor 9023 is fixed on the outside of the conveying frame 704. A second gear 9024 is provided at the output end of the side-folding motor 9023. The first gear 9022 and the second gear 9024 are meshed together.

[0045] When the conveying device 7 lifts the inner box 2, it drives the second gear 9024 to rotate, which in turn drives the first gear 9022 to rotate, thereby causing the shaft to rotate. The two sets of side folding blocks 9021 then move to fold the two side plates 202 of the inner box 2 upward. The folded inner box 2 is then placed inside the outer box 1 by the conveying device 7.

[0046] like Figure 6 , Figure 7 As shown, the lid device 903 is located behind the side folding mechanism 902. The lid device 903 includes a front pre-folding mechanism 9031 and a lid mechanism 9032.

[0047] The lid device 903 includes forming an inner corner for the connecting wall strip 105 of the outer box 1, pre-bending the leading edge of the outer box 1, and closing movement of the lid 102 of the outer box 1.

[0048] Specifically, during the process of the inner box 2 moving to the outer box conveying device 8, one side panel 202 of the inner box 2 contacts the inclined side, the rear side panel 202 folds up, the side folding block 9021 folds up both sides, and after the inner box 2 falls into the outer box 1, the outer box 1 is covered by the lid-closing device 903.

[0049] like Figure 10 As shown, the leading edge pre-folding mechanism 9031 includes a pre-folding lifting cylinder 9033 and two sets of pre-folding inner corner blocks 9034. The pre-folding lifting cylinder 9033 is fixed inside the outer box conveyor frame 801, and a pre-lifting block is fixed at the output end of the pre-folding lifting cylinder 9033.

[0050] Rotating rods 9035 are rotatably connected to both sides of the outer box conveyor frame 801. Each set of pre-folded inner corner blocks 9034 is tilted and fixed on the top surface of the rotating rod 9035. A spiral groove is opened on the surface of the rotating rod 9035. A traction block 9036 is slidably arranged inside the spiral groove. The end of each set of traction blocks 9036 away from the rotating rod 9035 is fixed to both ends of the pre-rising block.

[0051] The pre-folding block is used to fold the front edge 103 of the outer box 1 upward. When the front edge 103 of the box folds upward, the pulling block 9036 moves, causing the rotating rod 9035 to rotate. The pre-folding inner corner block 9034 is tilted to fold the connecting wall strip 105 inward, so that the front edge 103 of the box and the connecting wall strip 105 complete the pre-folding.

[0052] In one embodiment of this application, such as Figure 11 As shown, the lid mechanism 9032 includes an upward-folding cylinder 9044 and a U-shaped swing arm 9038, wherein, A U-shaped frame 9039 is fixed to the output end of the upward folding cylinder 9044. A pusher block 9040 is fixed to one side of the top surface of the U-shaped frame 9039. The top surface of the pusher block 9040 is provided with an inclined edge. Insert blocks 9041 are fixed to both ends of the other side of the top surface of the U-shaped frame 9039. Before the box-closing device 903 closes the box, the upward folding cylinder 9044 rises to press the pusher block 9040 and the insert block 9041 against the side wall of the outer box 1. When closing the box, it ensures that the frame wall 104 of the box cover 102 and the box body 101 of the box cover 102 do not get stuck together.

[0053] The U-shaped swing arm 9038 is rotatably connected to the inner wall of the outer box conveyor frame 801. The middle wall of the U-shaped swing arm 9038 is rotatably connected to the push roller 9042. The inner wall of the outer box conveyor frame 801 is provided with a swing arm motor 9043. The output end of the swing arm motor 9043 is connected to the rotation shaft of the U-shaped swing arm 9038. During the rotation of the U-shaped swing arm, the push roller 9042 contacts the box cover 102 and applies a pushing force to push the box cover 102 completely into place.

[0054] Specifically, when the outer box 1 is conveyed by the outer box conveying device 8 to the designated position of the lid mechanism 9032, the upper folding cylinder 9044 is activated. The upper folding cylinder 9044 starts working, driving the U-shaped frame to rise. The push block 9040 and the insert block 9041 are attached to the side wall of the outer box 1. Then, the swing arm motor 9043 drives the U-shaped swing arm to rotate. The push roller 9042 contacts the lid 102 as the U-shaped swing arm rotates and applies a pushing force to completely push the lid 102 closed, so that the lid 102 is tightly attached to the outer box 1.

[0055] In one embodiment of this application, such as Figure 5 As shown, the conveying linear module 702 is installed at the lifting end of the conveying lifting platform 701, and the two sets of conveying telescopic rods 703 are connected to the moving end of the conveying linear module 702. Each set of conveying frame 704 is installed at the moving end of each set of conveying telescopic rods 703.

[0056] The bottom of the support platform 4 is provided with a first support slot 705, and the conveying frame 704 can be inserted into the first support slot 705 to facilitate the lifting of the support platform 4.

[0057] The outer box conveyor 801 has a fixed lowering frame 804 on its platform. The lowering frame 804 has a lowering cylinder 8011 on its inner wall. The output end of the lowering cylinder 8011 is connected to a baffle 8012. After the inner box 2 is placed inside the outer box 1, the baffle 8012 descends to block the platform 4. At this time, the conveyor 704 moves out, so that the platform 4 stops inside the outer box 1.

[0058] It should be noted that a second bracket slot 606 is provided below the tray 4. After the tray 4 is placed inside the outer box 1, the conveyor 704 can be moved out after it descends.

When the photoelectric sensor senses the outer box 1, the pusher cylinder 11 is activated, and the pusher block 1101 pushes the outer box 1 onto the cardboard roller 1003 of the outer box conveying device 8, and the outer box 1 continues to be conveyed forward.

[0071] 4. During the process of the inner box 2 moving to the outer box conveying device 8, one side plate 202 contacts the inclined edge of the horizontal folding block 901, and the rear side plate 202 folds upward. When the conveying device 7 lifts the inner box 2, the side folding motor 9023 of the side folding mechanism 902 starts, and the side folding block 9021 folds the two side plates 202 of the inner box 2 upward through gear transmission.

[0072] 5. The outer box 1 is conveyed to the packaging device. When the outer box 1 contacts the photoelectric sensor, the outer box conveying device 8 stops, making the rear edge of the outer box 1 perpendicular to the horizontal folding block 901. The conveying device 7 places the folded inner box 2 into the outer box 1. The descending cylinder 8011 in the descending frame 804 causes the baffle 8012 to descend, blocking the platform 4. The conveying frame 704 moves out, and the platform 4 stops inside the outer box 1.

[0073] 6. The pre-folding lifting cylinder 9033 of the front pre-folding mechanism 9031 is activated, the pre-lifting block folds the front edge 103 of the outer box 1 upward, the traction block 9036 moves to rotate the rotating rod 9035, the pre-folding inner corner block 9034 folds inward to connect the wall strip 105, and the pre-folding of the front edge 103 of the box and the connecting wall strip 105 is completed.

[0074] 7. The upward folding cylinder 9044 of the lid-covering mechanism 9032 rises, and the push-side block 9040 and the insert block 9041 fit against the side wall of the outer box 1. The swing arm motor 9043 drives the U-shaped swing arm to rotate, and the push roller 9042 pushes the lid 102 to fully close the lid, completing the packaging of the entire cake.

[0075] In summary, the cake packaging box of this application can effectively protect the cake from shaking and deformation during transportation and sales, and can also provide convenient cutting space while maintaining good sealing and hygiene conditions.
