Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil lunch box production, in particular to an aluminum foil lunch box conveying system. Background Art

[0002] Aluminum foil lunch boxes are a widely used type of tableware. The thickness of aluminum foil lunch boxes is generally between 0.03mm and 0.20mm, and they can be divided into two types: wrinkled and wrinkle-free. They can also be divided into disposable and reusable types. Domestically, they are often called tinfoil lunch boxes. In fact, they are made of 3 series or 8 series aluminum ingots, which are cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor. They are formed by a one-time fully automatic cold stamping process using special equipment and molds;

[0003] During stamping, in order to ensure production efficiency, the tin foil is usually ejected from the mold after forming and then falls on the conveyor belt for transportation. At this time, since the tin foil is thin, it will be deformed after falling, which makes it inconvenient to pack and stack.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6The present invention provides a technical solution: an aluminum foil lunch box conveying system, comprising a mounting frame 1, a mounting plate 2 is fixedly connected to the upper side of the mounting frame 1, a motor 3 is fixedly connected to the lower right side of the mounting plate 2, the output end of the motor 3 is connected to a driving rod 4 through a bevel gear transmission, the front and rear end outer walls of the driving rod 4 are both rotatably connected to the inner wall of the mounting plate 2 through a bearing, a roller 5 is fixedly connected to the middle of the outer wall of the driving rod 4, two rollers 5 are arranged at both ends of the mounting plate 2, a conveyor belt 6 is sleeved on the outer side of the two rollers 5, the conveyor belt 6 is made of rubber, and a strip hole running through the middle of the conveyor belt 6 is opened up and down, the outer wall of the mounting plate 2 is located at the front side and the rear side of the conveyor belt 6, and two guide plates 7 are fixedly connected respectively, and the guide plate 7 on the rear side is located on the left side of the front guide plate 7, a stretching mechanism 8 is also arranged in the middle of the mounting frame 1, a turning mechanism 9 is arranged on the upper side of the mounting plate 2, and an exhaust mechanism 10 is arranged on the rear side of the mounting plate 2;

[0029] The height of the left side of the device is higher than that of the right side. The left side of the device should be brought close to the mold to ensure that the lunch box can fall to the left side of the device after being ejected. Then, the motor 3 drives the driving rod 4 to rotate, so that the driving rod 4 and the roller 5 drive the conveyor belt 6 to move, so that the conveyor belt 6 transports the lunch box. Moreover, since the height of the left side of the mounting plate 2 is higher than that of the right side of the mounting plate 2, the upper surface of the conveyor belt 6 is inclined, thereby buffering the impact of the lunch box falling and reducing the deformation of the lunch box.

[0030] The exhaust mechanism 10 includes a fan 101, the outer wall of the fan 101 is fixedly connected to the rear side of the mounting plate 2, the input end and the output end of the fan 101 are respectively fixedly connected with a first air duct 102 and a second air duct 104, the first air duct 102 and the second air duct 104 are respectively fixedly connected with a first air hopper 103 and a second air hopper 105 at one end away from the fan 101, and the second air hopper 105 and the first air hopper 103 are both located inside the conveyor belt 6, the outer walls of the second air hopper 105 and the first air hopper 103 are both fixedly connected to the outer wall of the mounting plate 2, the upper sides of the second air hopper 105 and the first air hopper 103 are both opened, the second air hopper 105 is located on the left side of the first air hopper 103, the interior of the second air hopper 105 is connected to the output end of the fan 101 through the second air duct 104, and the interior of the first air hopper 103 is connected to the input end of the fan 101 through the first air duct 102;

[0031] In the process of this device, air is sucked from the first air duct 102 side by the fan 101, and exhausted through the second air duct 104 side, so that the airflow is ejected upward through the second air bucket 105, and the airflow is discharged upward through the strip holes on the left side of the conveyor belt 6, so that the fallen lunch box is buffered by the airflow during the falling process, reducing the damage of the lunch box falling, and the airflow is discharged upward. Since one side of the lunch box is a concave structure, the inside of the groove is impacted by the airflow and turned upward, so that its more fragile edge position is upward, and then its more solid lower side contacts the upper side of the conveyor belt 6, and the surface orientation consistency rate of the lunch box can be increased in the process of reducing the deformation of the lunch box, which is convenient for later storage;

[0032] During the exhaust process of the fan 101, air is sucked through the first air duct 102, thereby generating a downward airflow on the upper side of the first air hopper 103, which can stabilize the lunch boxes that have fallen onto the surface of the conveyor belt 6, thereby reducing the tumbling or collision of the lunch boxes on the surface of the conveyor belt 6, thereby reducing deformation;

[0033] The stretching mechanism 8 includes a fixed component and a rotating rod 804 that can move up and down. The rotating rod 804 is located in the middle of the conveyor belt 6.

The bottom plate 802 is located at the lower side of the conveyor belt 6. The upper side of the outer wall of the mounting seat 803 is rotatably connected to one end of the rotating rod 804 through a bearing. The outer wall of the rotating rod 804 contacts the lower side of the inner wall of the conveyor belt 6. The bottom plate 802, the mounting seat 803, and the rotating rod 804 can all move downward, and the rotating rod 804 is located in the middle of the conveyor belt 6.

[0034] When transporting thin and soft lunch boxes, the spiral telescopic rod 801 can be rotated to push the bottom plate 802 and the mounting seat 803 upward, so that the outer wall of the rotating rod 804 does not contact the outer wall of the conveyor belt 6, so that the tension on the conveyor belt 6 is reduced, so that the upper surface is softer, and the lunch box is less likely to fall and be damaged. In addition, the reduction in the deformation of the conveyor belt 6 can reduce the area of ​​the strip holes opened on it, thereby reducing the airflow velocity on the upper surface, preventing the airflow from blowing the lunch box off the surface of the conveyor belt 6;

[0035] When dealing with a thicker lunch box, the spiral telescopic rod 801 can be rotated to move the bottom plate 802, the mounting seat 803 and the rotating rod 804 downward, so that the rotating rod 804 pulls the middle part of the conveyor belt 6 downward, so that the total length of the conveyor belt 6 becomes longer, so that it deforms downward, and the aperture of the strip hole on the upper side thereof is increased, so that the amount of airflow passing through is increased, and thus the thicker lunch box can be effectively buffered;

[0036] The flip mechanism 9 includes a connecting assembly and a lifting rod 905 on the connecting assembly, the lifting rod 905 is located on the upper side of the conveyor belt 6, and the lifting rod 905 can be deflected, the connecting assembly includes a bracket 901, the lower side of the bracket 901 is fixedly connected to the upper surface of the mounting plate 2, the middle part of the bracket 901 is fixedly connected to a monitoring module 902, the right side of the bracket 901 is fixedly connected to an articulated arm 903, the right side of the articulated arm 903 is hinged to an articulated frame 904, the lower side of the articulated frame 904 is rotatably connected to the lifting rod 905 through a bearing, and the side wall of the articulated frame 904 is hinged An electric telescopic rod 906 is connected, the other end of the electric telescopic rod 906 is hinged to the outer wall of the bracket 901, the hinged frame 904 can be deflected, and the length of the hinged frame 904 is greater than the height from the right end of the hinged arm 903 to the upper surface of the conveyor belt 6, the height of the left side of the conveyor belt 6 is higher than the height of the right side of the conveyor belt 6, and the turning mechanism 9 also includes a gear rod 907, the gear rod 907 is located on the inner left side of the conveyor belt 6, both ends of the gear rod 907 are rotatably connected to the outer wall of the mounting plate 2 through bearings, and the upper side of the outer wall of the gear rod 907 is in contact with the upper surface of the inner wall of the conveyor belt 6;

[0037] During the transportation of the lunch box, it will be pushed to the middle of the conveyor belt 6 by the guide plate 7, so that the movement stroke of the lunch box is consistent. After the lunch box passes the lower side of the bracket 901, the monitoring module 902 will monitor the front and back sides of the lunch box. When it is found that the lunch box is turned over, the electric telescopic rod 906 will be started to pull the articulated frame 904 to deflect, so that the lifting rod 905 will be lowered, so that it will squeeze the conveyor belt 6 downward to form a groove, so that one side of the lunch box will first move to the upper side of the lifting rod 905 during the movement, and then the electric telescopic rod 906 will push the articulated frame 904 to deflect it, so that the lifting rod 905 will be lifted upward, so that it can turn the lunch box over, so that the thicker bottom surface of the lunch box will contact the conveyor belt 6, avoid deformation during subsequent transportation and facilitate packing.
