Detailed Implementation

[0011] 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.

[0012] Example: Please see Figures 1 to 3 This utility model provides a technical solution: A film wrapping and flexible bundling device for rice packaging bags includes a conveyor roller conveyor 1, a palletizing assembly 2, and a film covering assembly 3. The palletizing assembly 2 is located at the conveying end of the conveyor roller conveyor 1, while the film covering assembly 3 is located at the conveying end. The conveyor roller conveyor 1 cooperates with a conveyor line so that the rice bags conveyed by the conveyor line fall onto the conveyor roller conveyor 1 at its conveying end. The palletizing assembly 2 includes a mounting frame 21, a lifting bracket 22, a servo electric cylinder 23, and a clamping buffer assembly 24. The mounting frame 21 is located at the conveying end of the conveyor roller conveying device 1. The lifting bracket 22 can pass through the conveyor roller conveying device 1 and is movably mounted on the mounting frame 21 and located below the conveyor roller conveying device 1. The lifting bracket 22 can pass between two conveyor rollers on the conveyor roller conveying device 1. The servo electric cylinder 23 is located on the mounting frame 21 and is poweredly connected to the lifting bracket 22. The clamping buffer assembly 24 is located on the mounting frame 21 and above the conveyor roller conveying device 1 and is used to clamp rice bags. When the rice bags arrive at the palletizing assembly 2 via the conveyor line, the servo cylinder 23 lifts the lifting bracket 22, thereby lifting the rice bags to the clamping buffer assembly 24, which clamps the rice bags. Then, the servo cylinder 23 drives the lifting bracket 22 to reset. The second rice bag arrives at the palletizing assembly 2 via the conveyor line, and the clamping buffer assembly 24 releases the rice bag, causing the first rice bag to fall onto the second rice bag. The servo cylinder 23 then drives the lifting bracket 22 to lift both rice bags to the clamping buffer assembly 24, so that the clamping buffer assembly 24 clamps both rice bags. This process is repeated layer by layer until the set number of layers is reached.

[0013] In a preferred embodiment, the lifting bracket 22 includes a mounting plate 221, lifting plates 222, and columns 223. The mounting plate 221 is movably mounted on the mounting frame 21 and is powered by the servo electric cylinder 23. The mounting plate 221 forms a vertically movable joint. At least two lifting plates 222 are arrayed on the mounting plate 221 via columns 223. The width of the lifting plate 222 is smaller than the spacing between two adjacent conveyor rollers on the conveyor roller conveying device 1. Figure 2 As shown, the diameter of the column 223 is smaller than the width of the lifting plate 222, so that both the lifting plate 222 and the column 223 can pass between the two conveying rollers on the conveying roller conveying device 1.

[0014] In a preferred embodiment, the clamping buffer assembly 24 includes a cylinder 241 and an L-shaped clamping plate 242. The two cylinders 241 are mounted on the mounting frame 21 and arranged on both sides of the conveying roller conveying device 1. The L-shaped clamping plate 242 is located at the actuating end of the cylinder 241. The cylinder 241 drives the L-shaped clamping plate 242 to insert into the bottom of the rice bag, thereby clamping the rice bag.

[0015] As a preferred embodiment, the coating component 3 is used to coat the rice bag. The coating component 3 is a conventional technical means for those skilled in the art, and its principle and solution will not be described in detail here.

[0016] The working principle of this utility model: In use, when a bag of rice arrives at the palletizing assembly 2 via the conveyor line, the servo cylinder 23 lifts the lifting bracket 22, thereby lifting the rice bag to the clamping buffer assembly 24. The cylinder 241 drives the L-shaped clamping plate 242 to insert into the bottom of the rice bag, thereby clamping the rice bag. Afterwards, the servo cylinder 23 drives the lifting bracket 22 to reset. The second bag of rice arrives at the palletizing assembly 2 via the conveyor line. The clamping buffer assembly 24 releases the rice bag, causing the first bag of rice to fall onto the second bag of rice. The servo cylinder 23 then drives the lifting bracket 22 to lift both bags of rice to the clamping buffer assembly 24, so that the clamping buffer assembly 24 clamps the two bags of rice. This process is repeated layer by layer until the set number of layers are reached, thus palletizing the rice bags.

[0017] After the rice bags are stacked, the rice bag stacks move towards the film coating assembly 3 along with the conveyor roller 1, and the film coating assembly 3 coats the rice bag stacks.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
