[0019] As a further description of the above technical solution:

[0020] The ferrule is sleeved with the spring tube, and the ferrule forms a movable structure through the ball nut and the screw rod.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] In the present invention, two conveyor belts can be used to transport packaging boxes and vegetables at the same time. The discharge valve can be used to deliver vegetables into the packaging boxes, so that the packaging operation can be continuous. The movable spring tube can be used to spread the vegetables flat in the packaging box to prevent them from piling up. The liftable spring tube can prevent the vegetables from falling from too high a position and falling out of the packaging box. In summary, the problems in the background technology are solved.

[0028] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 3 A packaging device for safe storage of vegetables includes a first conveyor frame 1, a packaging conveyor belt 2 is installed inside the first conveyor frame 1, a discharge guide roller 3 is installed at one end of the first conveyor frame 1, a support frame 4 is fixed to the upper end surface of the first conveyor frame 1, and a second conveyor frame 5 is installed on the upper end surface of the support frame 4, a vegetable conveyor belt 6 is installed inside the second conveyor frame 5, a discharge hopper 7 is fixed at one end of the second conveyor frame 5, a discharge valve 8 is installed on the lower end surface of the discharge hopper 7, and a spring tube 9 is installed at the output end below the discharge valve 8;

[0030] A plurality of guide rods 10 are mounted on the upper end surface of the first conveyor frame 1. A lifting plate 11 is sleeved on the surface of two guide rods 10. A hydraulic telescopic rod 12 is mounted between the first conveyor frame 1 and the lifting plate 11. A screw rod 13 is mounted between the two lifting plates 11. A ball nut 14 is threadedly engaged on the surface of the screw rod 13. A hoop 15 is mounted on one end of the ball nut 14. A servo motor 16 is mounted on the surface of the lifting plate 11.

[0031] At least one lifting conveyor belt is installed at one end of the vegetable conveyor belt 6 for delivering vegetables to the surface of the vegetable conveyor belt 6;

[0032] The packaging box is placed on the surface of the packaging conveyor belt 2, and the packaging box is sent to the bottom of the spring tube 9 by the packaging conveyor belt 2. At this time, the vegetables are transported by the vegetable conveyor belt 6, and the vegetables are sent to the discharge valve 8 through the discharge hopper 7. The vegetables are discharged from the open end below the spring tube 9 by controlling the opening and closing of the discharge valve 8;

[0033] At the same time, the output end of the servo motor 16 moves, which can drive the screw 13 to rotate, so that the ball nut 14 on its surface drives the hoop 15 to move, and the hoop 15 drives the open end of the spring tube 9 to move its position, so that the vegetables can be laid flat inside the packaging box;

[0034] The output end of the hydraulic telescopic rod 12 drives the lifting plate 11 to be raised and lowered, so that the hoop 15 can pull the open end of the spring tube 9 to be raised and lowered, thereby ensuring that the spring tube 9 is placed in a suitable position above the packaging box.

[0035] Furthermore, the second conveyor frame 5 is arranged parallel to and above the first conveyor frame 1 .

[0036] Furthermore, the lifting plate 11 forms a liftable structure with the first conveying frame 1 through the hydraulic telescopic rod 12 .

[0037] Furthermore, the output end of the servo motor 16 passes through the lifting plate 11 and is transmission-connected to the screw rod 13 .

[0038] Furthermore, the lower open end of the spring tube 9 is arranged above the packaging conveyor belt 2.

[0039] Furthermore, the output end of the discharge hopper 7 is connected to the input end of the spring tube 9 .

[0040] Furthermore, the ferrule 15 is sleeved with the spring tube 9 , and the ferrule 15 forms a movable structure through the ball nut 14 and the screw rod 13 .

[0041] Working principle: When in use, first place the packaging box on the surface of the packaging conveyor belt 2, and send the packaging box to the bottom of the spring tube 9 through the packaging conveyor belt 2. At this time, the vegetables are transported through the vegetable conveyor belt 6, and the vegetables are sent to the discharge valve 8 through the discharge hopper 7. The vegetables are discharged from the open end below the spring tube 9 by controlling the opening and closing of the discharge valve 8. At the same time, the output end of the servo motor 16 moves, which can drive the screw rod 13 to rotate, so that the ball nut 14 on its surface drives the hoop 15 to move, and the hoop 15 drives the open end of the spring tube 9 to move position, so that the vegetables can be flattened inside the packaging box. The output end of the hydraulic telescopic rod 12 drives the lifting plate 11 to rise and fall, so that the hoop 15 can pull the open end of the spring tube 9 to rise and fall, which can ensure that the spring tube 9 is placed in a suitable position above the packaging box. The working principle of the present invention is thus completed.
