[0034] The conveying roller 3 is provided with a plurality of push rods 4-4 on the surface of the conveying belt 4-3, and the push rods 4-4 are provided on the surface of the conveying belt 4-3. The push rods 4-4 move with the conveying belt 4-3. A plurality of outer frames 4-7 are provided on the top of the equipment frame 1. The side surfaces of the outer frames 4-7 are provided with transverse holes 4-8. Limiting plates 4-9 are provided between the outer frames 4-7 and connected to the transverse holes 4-8 through fixed through holes. The position of the limiting plates 4-9 can be moved according to the width of the cardboard. After adjustment, the fixing bolts 4-10 can be tightened to fix it. The cardboard is stacked between the limiting plates 4-9 inside the outer frames 4-7. During the rotation of the conveying belt 4-3, the push rods 4-4 will push the bottom cardboard outward to achieve the purpose of discharging and conveying.

[0035] Furthermore, the indentation component 5 includes a pair of telescopic cylinders 5-1, which are respectively fixed at the two ends of the top of the equipment frame 1, and the output end of the telescopic cylinder 5-1 is connected to a horizontal plate 5-2, and an auxiliary telescopic rod 5-3 is connected between the upper end surface of the equipment frame 1 and the horizontal plate 5-2. A pair of fixed rods 5-4 are arranged at the bottom of the horizontal plate 5-2, and a horizontal axis 5-5 is arranged between the fixed rods 5-4. A plurality of indentation wheels 5-6 are rotatably connected to the horizontal axis 5-5. A pair of support rods 5-7 are arranged on the two opposite end surfaces outside the horizontal plate 5-2, and a pressing roller 5-8 is rotatably connected between the support rods 5-7.

[0036] In this embodiment, in order to achieve the effect of stable indentation, an indentation component 5 is designed. Telescopic cylinders 5-1 are installed on both sides of the equipment frame 1. The output end of the telescopic cylinder 5-1 is connected to a horizontal plate 5-2. An auxiliary telescopic rod 5-3 is also installed between the bottom of the horizontal plate 5-2 and the equipment frame 1, which is used to cooperate with the height extension to improve the stability of the horizontal plate 5-2. A fixed rod 5-4 and a horizontal axis 5-5 are arranged at the bottom of the horizontal plate 5-2. The horizontal axis 5-5 is arranged between the fixed rods 5-4. A plurality of indentation wheels 5-6 are rotatably connected to the horizontal axis 5-5, which can perform indentation processing during the transportation of the cardboard. External frames 4-7 are arranged on both sides of the horizontal plate 5-2. A pressing roller 5-8 is rotatably connected to the external frame 4-7. [WU2] The pressing roller 5-8 will fit the surface of the cardboard and rotate with the transportation of the cardboard to avoid the outer edge from curling up during the indentation processing.

[0037] Furthermore, the outer frame 4 - 7 is an L-shaped structure as a whole, and several of the outer frames 4 - 7 are located at four opposite corners of the top of the equipment rack 1 .

[0038] In this embodiment, through the L-shaped structure, four outer frames 4-7 distributed at four corners form a frame structure for correcting cardboard to facilitate stacking and unloading.

[0039] Furthermore, both ends of the surface of the processing table 4-6 are bent downward in an arc shape, and the surface of the processing table 4-6 and the convex layer 4-1 are located at the same plane height.

[0040] In this embodiment, the arc-shaped bending transition is coordinated with the moving trajectory of the push rod 4-4 and maintained at the same height as the processing table 4-6, so as to facilitate the transportation of cardboard.

[0041] Furthermore, the push rod 4-4 is located at opposite ends of the processing table 4-6, and the bottom surface of the push rod 4-4 is higher than the surface of the processing table 4-6.

[0042] In this embodiment, push rods 4-4 are provided at both ends, which can push both sides of the cardboard at the same time to avoid deflection during the conveying process.

[0043] Furthermore, a notch 6 is provided at the bottom of the outer frame 4-7, and the height of the notch 6 is higher than the top height of the push rod 4-4.

[0044] In this embodiment, a notch 6 is provided at the bottom for the push rod 4 - 4 to pass through, and the size of the notch 6 is the same as the thickness of the paperboard, so as to ensure that the push rod 4 - 4 pushes out one paperboard each time.

[0045] Furthermore, the lower end surface of the pressing roller 5-8 is higher than the lower end height of the creasing wheel 5-6.

[0046] In this embodiment, due to the higher position of the pressing roller 5-8, the pressing roller 5-8 only needs to fit the surface of the cardboard without pressing, and is used to limit the cardboard so that it will not curl up during the creasing process.

[0047] Furthermore, the fixing bolts 4-10 connected to the two end surfaces of the limiting plate 4-9 are each a pair.

[0048] In this embodiment, by installing two fixing bolts 4-10, the limiting plate 4-9 can remain vertical after being fixed, and will not deflect and cause the cardboard to be stuck.

[0049] When indentation processing is required, according to the width of the cardboard, the position of the limit plate 4-9 is adjusted after screwing the fixing bolt 4-10, and the cardboard stack is placed inside the outer frame 4-7 and the limit plate 4-9. After placing, the drive motor 2 is started to control the rotation of the conveying roller 3, and the cardboard is pushed by the push rod 4-4 on the conveyor belt 4-3. When the cardboard moves to the indentation wheel 5-6, the indentation treatment is carried out, and the pressing roller 5-8 is kept in contact with the surface of the cardboard. During the indentation process, the outer side of the cardboard can be prevented from warping. After the indentation treatment, it is pushed outward with the push rod 4-4. According to the thickness of the cardboard, the telescopic cylinder 5-1 can be started to adjust the height of the cross plate 5-2.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
