[0021] The utility model has the following beneficial effects:

[0022] 1. The position of the material discharging frame is adjusted through the lifting assembly, so that the height between the bottom of the material discharging frame and the conveying plate is the height of one paper shell. Each time the conveying plate conveys one paper shell for indentation processing, and the side of the baffle strip can align one side of the paper shell.

[0043] The conveying plate 4 is arranged below the feeding frame 12. At one end of the top of the conveying plate 4, there are symmetrically arranged baffle strips 41. The top of the baffle strips 41 abuts against the bottom of the feeding frame 12, and the side of the baffle strips 41 abuts against one side of the cardboard on the conveying plate 4.

[0044] On the bottom plate 1, there is a centering assembly 6. The centering assembly 6 includes a pair of centering plates 61 which are symmetrically arranged on both sides of the first groove 13 and slidably connected to the bottom plate 1.

[0048] The position of the feeding frame 12 is adjusted by the lifting component 3 so that the height between the bottom of the feeding frame 12 and the conveying plate 4 is the height of a paper shell. The paper shell to be indented is placed in the feeding frame 12, and the bottom paper shell falls on the conveying plate 4, and the side of the paper shell abuts against the side of the baffle strip 41. When the moving component 5 is started to drive the conveying plate 4 to move to the indentation component 2, the baffle strip 41 abuts against the bottom of the feeding frame 12 to prevent the paper shell from continuing to fall onto the conveying plate 4. When the paper shell of the conveying plate 4 is sent to the bottom of the indentation component 2 and before the centering component 6 is started, the second spring 67 is in the indentation state. The paper shell is in a retracted state, at which time the electric telescopic rod 65 is started to push the second push block 64 to move, and the first push blocks 63 on both sides of the second push block 64 move relative to each other under the pressure of the first spring 67, thereby driving the centering plate 61 to move relative to each other to center the paper shell, and then starting the indentation component 2 to indent the paper shell. After completion, the paper shell is taken out, and the motor 51 is rotated in the reverse direction to move one end of the conveying plate 4 to the discharge frame 12. Without the obstruction of the baffle strip 41, the paper shell falls due to gravity, and the bottom paper shell falls onto the conveying plate 4, and the above operations are repeated to convey, center and indent the paper shell.

[0049] Preferably, a strip plate 15 is provided on the bottom plate 1. The strip plate 15 is provided on the side of the first groove 13 away from the conveying plate 4 to block the front end of the paper shell. The front and rear sides of the paper shell are aligned through the strip plate 15 and the baffle strip 41.

The first threaded rod 31 is rotated by rotating the handle 33, and the first movable block 32 moves in the axial direction of the first threaded rod 31, thereby driving the discharge frame 12 to rise or fall, so as to adjust the distance between the bottom of the discharge frame 12 and the base plate 1 to the thickness of a paper shell.

[0052] Preferably, a second moving block 34 is provided on the side of the material discharging frame 12. There are two second moving blocks 34, which are symmetrically distributed with the first moving block 32 as the center. A sliding rod 35 penetrates through the second moving block 34. The second moving block 34 is slidably connected to the sliding rod 35. The bottom of the sliding rod 35 is fixedly connected to the bottom plate 1. When the first threaded rod 31 rotates, the second moving block 34 and the sliding rod 35 can restrict the material discharging frame 12 axially, preventing the material discharging frame 12 from rotating with the first threaded rod 31 and ensuring that the material discharging frame 12 only moves along the axis of the first threaded rod 31.

[0053] Preferably, the moving assembly 5 includes a second threaded rod 52. A second groove 14 is formed in the first groove 13. The second threaded rod 52 is rotatably arranged in the second groove 14. One end of the second threaded rod 52 extends out of the second groove 14 and is connected to a motor 51. The motor 51 is fixed on one side of the bottom plate 1.

[0054] A third moving block 53 is provided at the bottom of the conveying plate 4. The third moving block 53 is slidably arranged in the second groove 14 and is threadedly connected to the second threaded rod 52. The motor 51 drives the second threaded rod 52 to rotate, thereby driving the third moving block 53 to move along the axis of the second threaded rod 52, and then driving the conveying plate 4 to slide along the first groove 13 to send the cardboard to the lower part of the indentation assembly 2.

[0055] Preferably, a third groove 43 is formed at one end of the top of the conveying plate 4. A second spring 42 is arranged in the third groove 43. The other end of the second spring 42 is fixedly connected to the bottom of the baffle strip 41. The second spring 42 is in a compressed state. When adjusting the height between the material discharging frame 12 and the conveying plate 4 to correspond to cardboard of different thicknesses, the second spring 42 generates a thrust on the baffle strip 41 due to the compression force, ensuring that the top of the baffle strip 41 always abuts against the bottom of the material discharging frame 12.

[0056] The working principle of the utility model is as follows: by rotating the handle 33, the first threaded rod 31 is driven to rotate, and the first moving block 32 moves in the axial direction of the first threaded rod 31, thereby driving the discharge frame 12 to rise or fall, so as to adjust the distance between the bottom of the discharge frame 12 and the bottom plate 1 to the thickness of a paper shell, and put the paper shell that needs to be indented into the discharge frame 12, and the paper shell at the bottom falls on the conveying plate 4, and the side of the paper shell is against the side of the baffle strip 41, and the motor 51 drives the second threaded rod 52 to rotate, thereby driving the third moving block 53 to move along the axial direction of the second threaded rod 52, thereby driving the conveying plate 4 to slide along the first groove 13 to the process below the indentation component 2, and the baffle strip 41 and the discharge frame 12 conflicts with the bottom of the paper shell to prevent it from continuing to fall onto the conveying plate 4. When the paper shell on the conveying plate 4 is sent to the bottom of the indentation component 2, the electric telescopic rod 65 is started to push the second push block 64 to move. The first push blocks 63 on both sides of the second push block 64 move relative to each other under the extrusion of the first spring 67, thereby driving the centering plate 61 to move relative to each other to center the paper shell. Then, the indentation component 2 is started to indent the paper shell. After completion, the paper shell is taken out, and the motor 51 is rotated in the reverse direction to move one end of the conveying plate 4 to the discharge frame 12. Without the obstruction of the baffle strip 41, the paper shell falls due to gravity, and the bottom paper shell falls onto the conveying plate 4. The above operations are repeated to convey, center and indent the paper shell.
