Description

Technical Field

[0001] The utility model relates to the field of mechanical design, in particular to a paper towel pile turning device. Background Art

[0002] Paper towels are widely used in daily life. To facilitate the use of paper towels, they are now generally packaged as tissue paper. The tissue paper inside the tissue paper is stacked by stacking multiple sheets of paper, while the tissue paper inside the single tissue paper is cut from a larger tissue paper stack.

[0003] Nowadays, stacking paper into a paper towel stack is often achieved mechanically. In order to facilitate the extraction of paper during use, the paper at the first position can be better pulled out, and the paper at the first position will be folded in half. However, due to the limitations of existing common mechanical processing, such as the multi-manipulator paper towel stacking mechanism disclosed in ZL202221314490.9, the paper at the first position will usually be located at the bottom of the paper towel stack after processing.

[0004] In order to make the paper folded in half at the bottom of the paper towel stack be placed at the top of the paper towel stack, the paper towel stack is generally turned over manually. However, the efficiency of manual turning is low, and the paper towel stack is prone to scattering and falling during the turning process, resulting in poor stability. Utility Model Content

[0009] The beneficial effects of the present invention are as follows: in the present invention, a stack of paper towels can be conveyed in a paper feeding channel, and the spacing between the two conveying mechanisms can be effectively adjusted by the operation of the lifting mechanism, thereby adjusting the size of the paper feeding channel to match the conveyance of paper towel stacks of different thicknesses. Moreover, when the stack of paper towels is turned over, the lifting mechanism can further operate so that the two conveying mechanisms effectively clamp the stack of paper towels. At this time, the rotating mechanism can operate to rotate the lifting mechanism, the guide column, and the conveying mechanism, thereby realizing the turning over of the stack of paper towels. The present invention can effectively realize the turning over and conveying of the stack of paper towels, has a high degree of automation, and can effectively fix the stack of paper towels during the turning process, is not prone to spreading or tipping over, and has good stability.

There can be multiple driven pulleys 13, all of which are rotatably mounted on the bracket 16 via pins. The conveyor belt 11 passes around the driving pulley 12 and each driven pulley 13.

[0030] The conveying mechanism 1 further includes a first tensioning wheel 17 . There can be multiple first tensioning wheels 17 . The multiple first tensioning wheels 17 are rotatably mounted on the motor base 15 through shafts, and all the first tensioning wheels 17 are against the conveyor belt 11 .

[0031] The conveying mechanism 1 also includes a second tensioning wheel 18 and a wheel frame 19. There are multiple wheel frames 19 and second tensioning wheels 18. All wheel frames 19 are fixedly connected to the bracket 16 by bolts. Multiple second tensioning wheels 18 are respectively installed on multiple wheel frames 19 in a one-to-one correspondence through pins. All second tensioning wheels 18 are against the conveyor belt 11.

[0032] There are two conveying mechanisms 1, and the brackets 16 of the two conveying mechanisms 1 are respectively connected to the connecting blocks 22 of different lifting mechanisms 2 by bolts, so that the lifting mechanism 2 can lift the conveying mechanism 1 connected to it. After setting, the two conveying mechanisms 1 can be located one above and one below, and the two conveying mechanisms 1 are arranged opposite to each other, and a paper feeding channel is provided between the conveyor belts 11 of the two conveying mechanisms 1.

[0033] The main gear 42 of the rotating member 41 is further provided with a first through hole 411 , and the frame 5 is provided with a second through hole 52 . The first through hole 411 and the second through hole 52 are connected, and the conveyor belts 11 of the two conveying mechanisms 1 both pass through the first through hole 411 and the second through hole 52 .

[0034] In addition, in order to ensure the stability of the conveying mechanism 1 during the lifting and rotation processes, in this embodiment, the number of rotating mechanisms 5 can preferably be two, and the number of lifting mechanisms 2 and guide pillars 3 can preferably be four, and they are divided into two groups accordingly, each group including two lifting mechanisms 2, one rotating mechanism 5 and two guide pillars 3.

Preferably, there are two connecting bars 7, each of which is bolted to multiple limit plates 6. The limit plates 6 are positioned on the sides of the paper feed channel.

[0038] When the paper towel stack turning device of the present invention is in use, the paper towel stack can be fed into the paper feeding channel through the external feeding device. At this time, the lifting cylinders 21 of each lifting mechanism 2 can work, and the lifting cylinders 21 can drive the connecting block 22 to move, thereby changing the distance between the two conveying mechanisms 1, that is, effectively changing the height of the paper feeding channel, so that the paper feeding channel can match the thickness of the paper towel stack. Afterwards, the conveying motor 14 can work and drive the driving wheel 12 to rotate, so that the conveyor belt 11 can move, and the paper towel stack located on the paper feeding channel can move with the movement of the conveyor belt 11, thereby realizing the conveyance of the paper towel stack.

[0039] When the stack of paper towels needs to be flipped, the lifting cylinder 21 of the lifting mechanism 2 can continue to work, so that the lifting cylinder 21 can further drive the connecting block 22 to move, thereby further reducing the distance between the two conveying mechanisms 1, and the two conveying mechanisms 1 can clamp the stack of paper towels to fix the stack of paper towels. Then the rotating motor 44 works, and the sub-gear 43 connected to the rotating motor 44 rotates to drive the rotating member 41 to rotate, thereby realizing the rotation of the conveying mechanism 1, and the stack of paper towels also rotates. When the rotation angle of the rotating member 41 reaches 180°, the stack of paper towels can be flipped, and then the lifting mechanism 2 can slightly increase the distance between the two conveying mechanisms 1, and then continue to convey the stack of paper towels, so that the stack of paper towels can be conveyed to subsequent processing equipment.

[0040] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
