[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figures 1 to 5 , a conveying and paper pressing device provided by the present invention includes a frame 1, a conveyor assembly 2 and a paper pressing assembly 3.

[0040] The conveyor assembly 2 is arranged on the frame 1 for conveying the paper to be compressed, and the paper feeding direction of the conveyor assembly 2 is set as the first direction.

[0041] The paper pressing assembly 3 includes a connecting frame 31, a pressing plate group 32 and a first driving member 33. The connecting frame 31 is slidably connected to the frame 1 along the first direction. A conveying space 310 for the paper to be compressed to pass through is formed between the connecting frame 31 and the conveyor assembly 2. The pressing plate group 32 is arranged on the connecting frame 31 for pressing the paper to be compressed passing through the conveying space 310 downward. The first driving member 33 is used to drive the connecting frame 31 to reciprocate along the first direction.

[0042] The conveying and paper pressing device provided by the present utility model comprises components such as the frame 1, the conveying assembly 2, and the paper pressing assembly 3. In practical applications, first start the conveying assembly 2, then place the paper to be compressed on the conveying assembly 2 and convey it along the first direction. When the paper to be compressed is conveyed to the conveying space 310, then compress the paper to be compressed downward through the pressing plate group 32. At this time, the first driving member 33 drives the connecting frame 31 to move along the first direction. After the paper to be compressed is conveyed for a certain distance in the compressed state, the pressing plate group 32 moves upward to release the compression of the paper to be compressed. At this time, the first driving member 33 drives the connecting frame 31 to continue moving along the first direction for a certain distance, and then the first driving member 33 drives the connecting frame 31 to move in the opposite direction of the first direction to adjust the connecting frame 31 to the initial position. After that, continue to place the paper to be compressed on the conveying assembly 2 to continue the processing; by setting the above structure, for the folded paper with creases formed at one-fourth of each piece of paper, it is the corresponding conveying and paper pressing device, which can stably compress the paper to be compressed, facilitating actual production.

[0043] Specifically, the "paper to be compressed" refers to folded paper formed by folding multiple layers in sequence; and before compression, the paper to be compressed occupies a large space, which is not conducive to packaging. Therefore, the present utility model provides a conveying and paper pressing device that can compress the paper to be compressed for folded paper with creases formed at one-fourth of each piece of paper, facilitating actual production.

[0044] Among them, since the paper to be compressed is relatively hard, for example, paper made of non-woven fabric material, after folding during paper production, the one-fourth folding of the topmost first piece of paper is a bit warped. The conveying and paper pressing device provided by the present utility model mainly serves to compress the one-fourth folding of the topmost first piece of paper and the entire paper to be compressed, so as to stably shape the paper to be compressed, making the compressed paper no longer warp. After being loaded into the packaging bag, it is convenient for the center point of the self-adhesive of the packaging bag to correspond to the end of the one-fourth folding of the topmost first piece of paper, so that the first piece of paper is easier to pick up, facilitating actual application.

[0045] In order to facilitate the stable compression of the paper to be compressed, the pressure plate group 32 includes a second driving member 321 and a pressure plate body 322. The second driving member 321 has a fixed end 3211 and a driving end 3212. The fixed end 3211 is arranged on the connecting frame 31. The pressure plate body 322 is arranged on the driving end 3212. The second driving member 321 is used to drive the pressure plate body 322 to move downward so as to compress the paper to be compressed passing through the conveying space 310 downward. The connecting frame 31 includes two side plates, which are located on both sides of the conveying assembly 2 and are respectively slidably connected to the frame 1 along the first direction. The fixed end 3211 is connected to the side plates. The pressing plate body 322 includes a connecting plate 3221 and a plurality of first pressing plates 3222. The connecting plate 3221 is provided at the driving end 3212. The plurality of first pressing plates 3222 are spaced apart from the connecting plate 3221. The second driving member 321 is used to drive the plurality of first pressing plates 3222 to move downward so as to compress the paper to be compressed passing through the conveying space 310 downward. The first pressing plate 3222 includes a guide portion 32221 and a pressing portion 32222 sequentially connected along the first direction. The guide portion 32221 is bent from high to low along the first direction and protrudes downward. The pressing portion 32222 is a flat plate. The first pressing plate 3222 is detachably provided on the connecting plate 3221. The connecting plate 3221 is slidably connected to the two side plates respectively. In actual application, the conveying component 2 is first started, and then the paper to be compressed is placed on the conveying component 2 and conveyed along the first direction. When the paper to be compressed is conveyed to the conveying space 310, the second driving member 321 drives the pressing plate body 322 to move downward so as to compress the paper to be compressed passing through the conveying space 310 downward (because the connecting plate 3221 is slidably connected to the two side plates respectively, the downward movement process of the first pressing plate 3222 is more stable. In addition, because the guide part 32221 can more smoothly press the quarter folded paper part that is raised above the paper to be compressed, the paper to be compressed can be stably Compression. ), at this time, the first driving member 33 drives the connecting frame 31 to move along the first direction, and after the paper to be compressed continues to be conveyed for a distance in the compressed state, the pressing plate group 32 moves upward to release the compression of the paper to be compressed, and at this time, the first driving member 33 drives the connecting frame 31 to continue to move for a distance in the first direction, and then the first driving member 33 drives the connecting frame 31 to move in the opposite direction of the first direction, so as to adjust the connecting frame 31 to the initial position, and then the paper to be compressed is continued to be placed on the conveying assembly 2 for continuous processing; by setting the above-mentioned specific structure, the paper to be compressed can be stably compressed.

[0046] In order to further improve the compression effect of the paper to be compressed, a sliding groove 311 is formed at the bottom of the connecting frame 31, and the frame 1 is provided with a sliding block 11. The connecting frame 31 is slidably connected to the sliding block 11 along the first direction via the sliding groove 311. The first driving member 33 includes a first connecting rod 331, a second connecting rod 332, a crank body 333 and a driving body 334.

The driving body 334 is provided on the frame 1 to drive the crank body 333 to rotate and the first connecting rod 331 and the second connecting rod 332 to swing, so as to drive the connecting frame 31 to reciprocate along the first direction. By providing the sliding groove 311, the sliding block 11, the first connecting rod 331, the second connecting rod 332, the crank body 333 and the driving body 334 and other components, the crank body 333 can be driven to rotate and the first connecting rod 331 and the second connecting rod 332 can be driven to swing, so as to drive the connecting frame 31 to reciprocate along the first direction. This design makes the paper to be compressed more stable when it continues to be transported for a distance in a compressed state, which is convenient for actual production.
