Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil lunch box processing equipment, specifically, it relates to an aluminum foil lunch box stacking and pressing device. Background Technology

[0002] Aluminum foil lunch boxes are tableware made from 3-series or 8-series aluminum ingots, mainly using 8011 or 3003 aluminum alloys. They are processed into aluminum foil master rolls with a thickness of 0.03-0.20mm through cold rolling or hot rolling processes, and then cold stamped into shape. During the production process, textured molds are used to extrude aluminum foil sheets, forming both wrinkled and wrinkle-free shapes.

[0003] Chinese Patent CN223059443U discloses a pressing device for formed aluminum foil lunch boxes. It includes an operating table with a positioning plate welded to its top. Two identical sliding plates are mounted on the top of the operating table, fitting against the surface of the positioning plate. Six symmetrical grooves are formed on the surface of the positioning plate, and three identical sliders are welded to the side of the sliding plate closest to the positioning plate. This invention places stacked aluminum foil lunch boxes at the angle between the positioning plate and the top of the operating table. Starting the motor allows the sliding plates to slide towards the positioning plate, aligning the stacked lunch boxes. Then, activating the cylinder causes the pressure plate to slide downwards, pressing the stacked lunch boxes. This device can align and press stacked aluminum foil lunch boxes, preventing deformation during user pressing and reducing the production of defective products.

[0004] The above technical solution has the following drawbacks:

[0005] To increase their support, stability, and friction, aluminum foil lunch boxes on the market often have grooves (i.e., wrinkled shapes) on their surface. At the same time, aluminum foil lunch boxes are not necessarily square boxes. When using the pressing device mentioned above to organize them, although it can prevent wrinkles and deformation between the aluminum foil lunch boxes during pressing, it cannot prevent deformation of the grooves in the aluminum foil lunch boxes themselves, and it is also not suitable for aluminum foil lunch boxes for bowls. Utility Model Content

[0006] To address the above deficiencies, this utility model provides an aluminum foil lunch box stacking and pressing device, including a workbench. Each of the four corners of the workbench is provided with a set of positioning grooves. Each set of positioning grooves is used to install positioning plates adapted to aluminum foil lunch boxes of different shapes. Each set of positioning grooves has a corresponding slot at the end facing the center of the workbench. The slot is used to fix a vibration rod.

[0007] The vibrating rod includes a rod body, each of which is connected to a miniature vibrating motor at the bottom of the workbench. The miniature vibrating motor is fixed on a motor base, and the motor base is connected to the bottom of the workbench via a connecting rod.

[0008] An air pump is also installed at the bottom of the workbench. The air outlet of the air pump is connected to an air outlet hopper for applying air pressure to the aluminum foil lunch box via a hose. The air outlet hopper is fixed by an air outlet frame.

[0009] Furthermore, the positioning plate includes a corner plate adapted to a square box-shaped aluminum foil lunch box and an arc-shaped plate adapted to a round bowl-shaped aluminum foil lunch box.

[0010] Furthermore, the top of the positioning plate is hinged to an outwardly extending guide plate via a spring pin.

[0011] Furthermore, a connecting column is fixed to the top of the micro vibration motor, and a fixing groove is opened on the top of the connecting column. The rod body is fixed by inserting into the fixing groove through a bottom-fixed plug.

[0012] The upper surface of the motor base and the bottom surface of the workbench are each provided with a set of guide grooves, and the two sets of guide grooves correspond to each other. Each guide groove is slidably connected to a slider, and the two sliders located on the same vertical line are respectively fixed to the two ends of the connecting rod between them.

[0013] Furthermore, the outer surface of the rod is fitted with a food-grade silicone sleeve.

[0014] Furthermore, the air outlet of the air pump is rotatably connected to the hose via a pipe rotary joint.

[0015] Furthermore, the wind turbine frame and the workbench are rotatably connected via a rotating shaft.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] Compared to traditional pressing devices, the mechanical pressing structure has been eliminated. By using airflow to generate downward pressure, the uneven aluminum foil lunch boxes can be straightened and moved down between the vibrating rod and the positioning plate. This prevents wrinkled aluminum foil lunch boxes from deforming due to compression. At the same time, the vibration generated by the vibrating rod can shake and correct misaligned aluminum foil lunch boxes, achieving the function of neat storage.

[0018] Additionally, different shaped positioning plates can be selected according to the needs of different aluminum foil lunch boxes, which has a good adaptability effect. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figures 1 to 2 As shown, this embodiment provides an aluminum foil lunch box stacking and pressing device, including a workbench 1. A set of positioning grooves 2 are provided at each of the four corners of the workbench 1. Each set of positioning grooves 2 is used to install positioning plates adapted to aluminum foil lunch boxes of different shapes, such as… Figure 1 As shown in the upper left and upper right corners of the middle workbench 1, the positioning plate includes a corner plate 3 adapted to a square box-shaped aluminum foil lunch box and an arc plate 4 adapted to a round bowl-shaped aluminum foil lunch box. The top of the corner plate 3 is hinged to an outwardly extending guide plate 5 by a spring pin, while the arc plate 4 needs to be fitted with a matching fan-shaped guide plate 5, which will not be described in detail here. In addition, aluminum foil lunch boxes of different sizes can also be adapted through the positioning groove 2 at the lower left or lower right corner. The spacing of each set of positioning grooves 2 can be different.

[0025] Each set of positioning slots 2 has a corresponding slot 6 at one end facing the center of the workbench 1. The slot 6 is used to fix the vibration rod 7. The slot 6 should be adapted according to the adjacent positioning slots 2. For example, for a box-shaped aluminum foil lunch box, the two sides of the end corner need to be limited (two vibration rods 7 are sufficient), while for a bowl-shaped aluminum foil lunch box, at least three vibration rods 7 are needed to adapt to its curved surface. This will not be elaborated here.

[0026] The vibrating rod 7 includes a rod body 71, and the outer surface of the rod body 71 is covered with a food-grade silicone sleeve 72 to reduce wear on the aluminum foil lunch box. Each rod body 71 is connected to a miniature vibration motor 75 at the bottom of the workbench 1. The miniature vibration motor 75 is fixed on a motor base 76, and the motor base 76 is connected to the bottom of the workbench 1 through a connecting rod 78.

[0027] In detail, a connecting column 74 is fixed to the top of the micro vibration motor 75. A fixing groove is opened on the top of the connecting column 74. The rod 71 is inserted into the fixing groove and fixed by the bottom fixed plug 73. A set of guide grooves 77 are opened on the upper surface of the motor base 76 and the bottom surface of the workbench 1, and the two sets of guide grooves 77 correspond to each other. A slider is slidably connected in each guide groove 77. Two sliders located on the same vertical line are fixed to the two ends of the connecting rod 78 between them. Its function is to generate vibration through the micro vibration motor 75, drive the vibration rod 71 to vibrate, thereby vibrating the corners of the aluminum foil lunch box and shaking it to tidy it up. The sliding connecting rod 78 is to adapt to the resonance of the micro vibration motor 75 and will not affect its service life due to fixation.

[0028] In addition, the diameter of the slot 6 should be greater than the diameter of the rod 71 and less than the diameter of the silicone sleeve 72, so as to leave a certain vibration space for the rod 71.

[0029] An air pump 8 is also installed at the bottom of the workbench 1. The air outlet of the air pump 8 is rotatably connected to the hose 10 through a pipe swivel joint 9, which can be adjusted to match the different positions of the positioning plate. The hose 10 is connected to an air outlet 12 for applying air pressure to the aluminum foil lunch boxes. The air outlet 12 is fixed by an air outlet frame 11, which is rotatably connected to the workbench 1 through a rotating shaft. By supplying air through the air pump 8 (adjusted to be located at the top of the aluminum foil lunch boxes), the aluminum foil lunch boxes located between the positioning plate and the vibration rod 7 can be subjected to downward pressure. Combined with the vibration of the vibration rod 7, the stacked aluminum foil lunch boxes can be automatically reset and sorted.

[0030] It should be noted that the miniature vibration motor 75 at each corner should be controlled by the same controller, and the air pump 8 can also achieve intermittent pressure application through intermittent air supply mode.

[0031] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
