Description

Technical Field

[0001] This utility model belongs to the field of cake box processing technology, and specifically relates to an alignment structure for folding edges of cake paper boxes. Background Technology

[0002] Existing cake box folding machines are mainly used in the cake packaging production process to fold the edges of the cylindrical body of the cake box, making the cake box more beautiful, increasing the stability of the connection with the lid, and preventing the edges from scratching the user.

[0003] Currently, cake box folding machines include a semi-automatic 360-degree solid edge rolling machine for cake boxes. This device uses the cooperation of a bottom support plate and springs and clips fixed to the top or inner cavity to align the cake box. Then, the pressure rod, alignment plate and gluing structure in the device complete the edge rolling of the cylindrical body of the cake box.

[0004] However, when using the existing semi-automatic 360-degree solid edge rolling machine for cake boxes, if the diameter of the cake box is slightly larger than the bottom tray, the bottom tray of the appropriate size needs to be replaced in order to complete the alignment of the cake box during processing. If the edge rolling is performed on cake boxes of different diameters in the same batch, the bottom tray needs to be frequently disassembled and reassembled, which affects the processing efficiency of subsequent cake boxes. Utility Model Content

[0005] The purpose of this utility model is to provide an alignment structure for folding the edges of cake boxes. Its advantage is that when processing the edge-rolling of cake boxes of different diameters in the same batch, it is not necessary to frequently change the bottom tray, and the alignment of cake boxes of different diameters can be completed, thereby increasing the versatility of the device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a folding alignment structure for a cake box, comprising a load-bearing shell, four auxiliary plates fixedly installed on the top of the load-bearing shell, a positioning plate movably connected between opposite sides of every two auxiliary plates, a connecting plate fixedly installed at the bottom of the positioning plate, an electric push rod fixedly installed on the side of the connecting plate near the load-bearing shell, the electric push rod being fixedly installed with the load-bearing shell on the side near the load-bearing shell, an alignment plate slidably connected between opposite sides of the inner cavity of every two positioning plates, a positioning assembly fixedly installed on the side of the alignment plate near the center of the load-bearing shell by bolts, the positioning assembly comprising a positioning shell, the side of the positioning shell near the positioning plate being movably connected to the positioning plate.

[0007] Using the above technical solution: When using this device to roll the edges of cake boxes of different diameters from the same batch, the user simultaneously activates the electric push rod. The electric push rod, through the connecting plate, moves the positioning plate and its connected components away from the center of the load-bearing shell. After the positioning plate moves to the designated position, the electric push rod is turned off, and the cake box to be rolled can be aligned through the circular area formed between the four positioning plates. Furthermore, when disassembling the alignment component formed by the worn return spring after long-term use, the user can use a hex screwdriver or an electric hex screwdriver to disconnect the bolt from the threaded connection shell, thus disassembling the alignment plate and the positioning component. Then, the user pulls the positioning shell away from the positioning plate to disengage the mounting block from the mounting shell, thus completing the disassembly of the alignment component formed by the worn return spring after long-term use.

[0008] The present invention is further configured such that a limiting shell is fixedly installed on the top and bottom of both sides of the inner cavity of the positioning shell, and a threaded connecting shell is slidably connected to the surface of the limiting shell. The threaded connecting shell is fixedly installed to the alignment plate by bolts. A return spring is fixedly installed on the side of the threaded connecting shell away from the alignment plate, and a movable shell is fixedly installed on the side of the return spring close to the inner cavity of the positioning shell. The inner cavity of the movable shell is slidably connected to the surface of the limiting shell.

[0009] The above technical solution is adopted: by setting a reset spring, the alignment plate can provide elastic buffer when aligning with the cake box, so that the alignment plate forms a flexible clamp when contacting the cake box, which not only prevents the box from deforming due to rigid compression, but also adapts to the size deviation of the box through elasticity, ensuring accurate alignment. The bolt connection between the threaded connecting shell and the alignment plate is easy to disassemble.

[0010] The present invention is further configured such that a positioning ring is fixedly installed on the opposite side of the threaded connecting shell and the movable shell, and the inner cavity of the positioning ring is fixedly installed with the return spring.

[0011] The above technical solution is adopted: the two ends of the return spring are fixed by the positioning ring to prevent it from falling off the threaded connection shell or movable shell during the extension and retraction process, thus ensuring stable transmission of elastic force.

[0012] The present invention is further configured such that a threaded rod is rotatably connected to the inner cavity of the limiting shell, a threaded sleeve is threadedly connected to the side of the threaded rod near the movable shell, the surface of the threaded sleeve is fixedly installed with the inner cavity of the movable shell, and a knob is engaged on the side of the threaded rod away from the inner wall of the limiting shell, and the side of the knob near the positioning shell is in contact with the positioning shell.

[0013] The above technical solution is adopted: by rotating the knob to drive the threaded rod to rotate, the threaded sleeve and the threaded rod are used to push the movable shell to slide along the limiting shell, thereby adjusting the initial compression of the reset spring and realizing the precise adjustment of the initial alignment force of the alignment plate. This structure can adjust the alignment force according to the paper box material, avoiding excessive force to damage the paper box or insufficient force to cause loosening of the alignment, and improving the adaptability of the device to paper boxes of different materials.

[0014] The present invention is further configured such that a limiting rod is fixedly installed on the side of the alignment plate near the positioning plate, and the limiting rod passes through the positioning plate and is slidably connected to the inner cavity of the positioning shell on the side near the positioning shell.

[0015] The above technical solution uses a limiting rod to provide dual guidance for the movement and installation trajectory of the positioning plate, ensuring that the positioning plate remains horizontal when it elastically expands or moves with the positioning plate, thus avoiding misalignment with the cardboard box due to offset.

[0016] The present invention is further configured such that an installation block is fixedly installed at the bottom of the positioning shell, the installation shell is snapped onto the surface of the installation block, and the side of the installation shell near the connecting plate is fixedly installed with the connecting plate.

[0017] The above technical solution enables quick assembly and disassembly of the positioning shell and the connecting plate by snapping the mounting block into the mounting shell. When the return spring or threaded rod in the positioning assembly malfunctions and needs to be replaced, the positioning shell can be removed simply by detaching the mounting block from the mounting shell and replacing it with a new positioning shell with the same structure. No other parts need to be disassembled, thus improving maintenance efficiency.

[0018] In summary, this utility model has the following beneficial effects: 1. When using this device to roll the edges of cake boxes of different diameters from the same batch, the user should simultaneously activate the electric push rod. The electric push rod will drive the positioning plate and its connected components away from the center of the load-bearing shell through the connecting plate. After the positioning plate moves to the designated position, the electric push rod should be turned off. The cake box that needs to be rolled can then be aligned through the circular area formed between the four positioning plates. 2. When disassembling the alignment assembly formed by the worn return spring after long-term use, the user can use a hex screwdriver or electric hex screwdriver to disconnect the bolt from the threaded connection housing, thus disassembling the alignment plate and the positioning assembly. Then, the user can pull the positioning housing away from the positioning plate to disengage the mounting block from the mounting housing, thus completing the disassembly of the alignment assembly formed by the worn return spring after long-term use.

The side of the electric push rod 5 near the load-bearing shell 1 is fixedly installed with the load-bearing shell 1.

[0023] Brief description of usage: When aligning cake boxes that need edge rolling, simply place the cake box to be rolled in the circular support area formed by the auxiliary plate 2 and the positioning plate while keeping the device in its original state. The alignment of the cake box to be rolled can be completed by the return spring 804, the threaded connecting shell 803, and the alignment plate 6 fixed to the threaded connecting shell 803 by bolts 7. When using this device to roll the edges of cake boxes of different diameters in the same batch, the user should simultaneously activate the electric push rod 5. The electric push rod 5 will drive the positioning plate 3 and the components connected to it away from the center of the load-bearing shell 1 through the connecting plate 4. After the positioning plate 3 moves to the designated position, the electric push rod 5 will be turned off. The cake box to be rolled can then be aligned through the circular area formed between the four positioning plates 3.

[0024] Example 2: refer to Figure 1 and Figure 3A cake box folding alignment structure includes four positioning plates 3. Alignment plates 6 are slidably connected to opposite sides of the inner cavity of every two positioning plates 3. A positioning assembly 8 is fixedly installed on the side of the alignment plate 6 near the center of the load-bearing shell 1 by bolts 7. The positioning assembly 8 includes a positioning shell 801. The side of the positioning shell 801 near the positioning plate 3 is movably connected to the positioning plate 3.

[0025] Furthermore, a limiting shell 802 is fixedly installed on the top and bottom of both sides of the inner cavity of the positioning shell 801. A threaded connecting shell 803 is slidably connected to the surface of the limiting shell 802. The threaded connecting shell 803 is fixedly installed to the alignment plate 6 by bolts 7. A return spring 804 is fixedly installed on the side of the threaded connecting shell 803 away from the alignment plate 6. A movable shell 805 is fixedly installed on the side of the return spring 804 close to the inner cavity of the positioning shell 801. The inner cavity of the movable shell 805 is slidably connected to the surface of the limiting shell 802.

[0026] Furthermore, a positioning ring 806 is fixedly installed on the opposite side of the threaded connection shell 803 and the movable shell 805, and the inner cavity of the positioning ring 806 is fixedly installed with the return spring 804.

[0027] Furthermore, a threaded rod 807 is rotatably connected to the inner cavity of the limiting shell 802. A threaded sleeve 808 is threadedly connected to the side of the threaded rod 807 near the movable shell 805. The surface of the threaded sleeve 808 is fixedly installed with the inner cavity of the movable shell 805. A knob 809 is engaged on the side of the threaded rod 807 away from the inner wall of the limiting shell 802. The side of the knob 809 near the positioning shell 801 contacts the positioning shell 801.

[0028] Furthermore, a limiting rod 810 is fixedly installed on the side of the alignment plate 6 near the positioning plate 3. The limiting rod 810 passes through the positioning plate 3 and is slidably connected to the inner cavity of the positioning shell 801 on the side near the positioning shell 801.

[0029] Furthermore, a mounting block 811 is fixedly installed on the bottom of the positioning shell 801, and a mounting shell 812 is snapped onto the surface of the mounting block 811. The side of the mounting shell 812 closest to the connecting plate 4 is fixedly installed with the connecting plate 4.

[0030] Brief description of usage: When disassembling the alignment assembly formed by the worn return spring 804 after long-term use, the user can use a hex screwdriver or electric hex screwdriver to disconnect the bolt 7 from the threaded connection shell 803, thus disassembling the alignment plate 6 from the positioning assembly 8. Then, the user pulls the positioning shell 801 away from the positioning plate 3, disengaging the mounting block 811 from the mounting shell 812, completing the disassembly of the alignment assembly formed by the worn return spring 804 after long-term use. The return spring 804 provides elastic cushioning for the alignment plate 6 when aligning with the cake box, creating a flexible clamping effect upon contact with the cake box. This prevents deformation of the cake box due to rigid compression and allows the elastic force to adapt to dimensional deviations, ensuring accurate alignment. The bolt 7 connection between the threaded connection shell 803 and the alignment plate 6 facilitates disassembly. The positioning ring 806 connects both ends of the return spring 804. The positioning ring 806 secures the two ends of the return spring 804 to prevent it from detaching from the threaded connection shell 803 or the movable shell 805 during extension and retraction, ensuring stable elastic force transmission. The limiting rod 810 provides dual guidance for the movement and installation trajectory of the positioning plate 6, ensuring that the positioning plate 6 remains horizontal during elastic extension and retraction or movement with the positioning plate 3, preventing misalignment with the cardboard box due to offset. The mounting block 811 engages with the mounting shell 812, enabling quick assembly and disassembly of the positioning shell 801 and the connecting plate 4. When the return spring 804 or threaded rod 807 within the positioning assembly 8 malfunctions and needs replacement, simply detach the mounting block 811 from the mounting shell 812 to remove the positioning shell 801 and replace it with a new positioning shell 801 with the same structure, without disassembling other components, thus improving maintenance efficiency.

[0031] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
