Technical Field

[0001] The utility model relates to the technical field of paper unloading equipment, in particular to a pneumatic opening and closing paper retaining wall. Background Art

[0002] Paper, as the main printing material, needs to be continuously fed through pallets. When the cardboard is piled up to a certain height, that is, a stack is completed, the stack needs to be transferred to the pallet and removed. The neatness of the stack and the efficiency of stack transfer are also particularly important.

[0003] In the prior art, the technical solution of the Chinese patent document (Announcement No.: CN217624266U, Patent Name: Paper Stack Conveyor Line and Paper Stack Automatic Tidying and Transfer Device) discloses that "when the paper stacking workbench moves to the second baffle, the pressing arm rises, and the first lifting assembly controls the bottom surface of the first baffle to descend to the height of the paper stacking workbench, and moves to one side of the paper stack to block the paper stack, and then the paper stacking workbench is reset. At this time, the paper stack is blocked by the first baffle and transferred to the pallet on the pallet lifting platform, and the paper stack transfer operation is completed."

[0004] Combined with the description and drawings of the patent document, the distance between the first baffle and the second baffle of the device remains unchanged, which limits the number of paper stacks that can be transferred to the pallet by the device and makes it impossible to transfer multiple paper stacks according to the length of the pallet.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] like Figures 1 to 3 As shown, a pneumatic opening and closing paper stop wall comprises a first wall 1, a second wall 2 and a frame 3 for accommodating the opening and closing of the first wall 1 and the second wall 2. Drive components 4 are hinged on both sides of the frame 3. The drive components 4 are rotatably connected to the mounting surfaces of the first wall 1 and the second wall 2 respectively. When the drive components 4 are started, the flat surfaces of the first wall 1 and the second wall 2 are spliced ​​together to form a paper stop area. The area of ​​the paper stop area formed by the splicing of the first wall 1 and the second wall 2 is larger than that of a general paper stop board. With the cooperation of the paper unloading equipment, the paper stack is transported to the paper stop area, and the paper stack is transferred to a pallet while the paper stack is blocked and leveled. Multiple paper stacks can also be transferred according to the length of the pallet. When the previous paper stack is blocked by the paper stop area, the next paper stack will be close to the previous paper stack, and the blocking and leveling operations are performed together, and then multiple paper stacks are transferred to the pallet, thereby improving the transfer efficiency. In addition, the drive component 4 can also control the opening of the first wall 1 and the second wall 2, so that the transfer of paper boards can be satisfied in venues with limited left and right space.

[0028] Specifically, Figures 3 to 7As shown, the frame 3 includes a first side frame 301 and a second side frame 302, a first horizontal frame 303 and a second horizontal frame 304 are arranged above the first side frame 301 and the second side frame 302, and a pad 305 is arranged below the first side frame 301 and the second side frame 302. The pad 305 is distributed with a plurality of mounting holes, and the first side frame 301 and the second side frame 302 can be fixed in position by using screws to pass through the mounting holes.

[0029] The mounting surfaces of the first wall 1 and the second wall 2 are rotatably connected to the movable end of the driving component 4, and the mounting surfaces of the first side frame 301 and the second side frame 302 are hinged to the fixed end of the driving component 4. The driving component 4 is a driving cylinder, and the cylinder ends of the two driving cylinders are respectively hinged to the mounting surfaces of the first side frame 301 and the second side frame 302, and the cylinder rod ends of the two driving cylinders are respectively rotatably connected to the middle of the first wall 1 and the second wall 2. When the cylinder rods of the two driving cylinders are extended, they will drive the first wall 1 and the second wall 2 to be pieced together to form a paper blocking area. When one side of the paper stack contacts the paper blocking area, the paper stack will be blocked and become flat. Then, through the cooperation of the paper blocking area and the paper unloading equipment, the whole stack of cardboard can be quickly transferred to the pallet. It is convenient and fast to use and saves labor costs. When the cylinder rods of the two driving cylinders are retracted, the first wall 1 and the second wall 2 will be driven to open to form a transportation area. Even under the condition of limited left and right of the site, the whole stack of cardboard on the pallet can be transported to other designated locations.

[0030] A limiting assembly 5 is provided in the middle of the first transverse frame 303, and the limiting assembly 5 includes a cylinder support frame 501 and a sliding frame 502. The cylinder support frame 501 is provided above the first transverse frame 303, and the sliding frame 502 is provided at the side of the first transverse frame 303. The cylinder support frame 501 is provided with a cylinder 504, and the telescopic rod of the cylinder 504 is connected with a fixing member 503, and the fixing member 503 is slidably provided in the sliding frame 502. A limiting frame 7 is provided below the first transverse frame 303, and the limiting frame 7 is provided with two limiting rods 701. A limiting frame 101 is provided at the joint ends of the first wall 1 and the second wall 2, and one side of the upper end of the limiting frame 101 corresponds to the limiting rod 701, and a limiting member 102 is provided on the other side of the upper end of the limiting frame 101. 02 is provided with a recessed position 1021, and the end of the fixing member 503 corresponds to the recessed position 1021. When the first wall 1 and the second wall 2 are assembled, the end of the limiting rod 701 abuts against the upper end of the limiting frame 101, and the cylinder 504 is started to extend the telescopic rod, driving the fixing member 503 to move downward and engage with the recessed position 1021, thereby fixing the position of the first wall 1 and the second wall 2, and effectively preventing the first wall 1 and the second wall 2 from being affected by the impact force of the cardboard during paper unloading, causing the position to change, resulting in paper falling over. After the paper blocking is completed, the cylinder 504 is started to shrink the telescopic rod, driving the fixing member 503 to move upward and disengage from the engaging state with the recessed position 1021, thereby facilitating the first wall 1 and the second wall 2 to perform the next opening operation.

[0031] Limiting columns 6 are arranged between the first side frame 301 and the first wall 1, and between the second side frame 302 and the second wall 2. One end of the limiting column 6 is fixed on the first cross frame 303, and the other end of the limiting column 6 is fixed on the pad 305. The limiting column 6 plays a limiting role to prevent the first wall 1 and the second wall 2 from colliding with the first side frame 301 and the second side frame 302 during opening and closing operations.
