DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 10 The present invention provides two technical solutions, which specifically include the following embodiments:

[0033] Embodiment 1:

[0034] In the embodiment of the present invention, reference Figure 1-Figure 10 A corrugated cardboard printing quality inspection device includes a machine body 1, conveyor belts 2 are arranged on both sides of the machine body 1 for conveying a cardboard body 3, a rectangular inspection frame 5 is arranged between the two conveyor belts 2, and a distance is left between the two conveyor belts 2 and the rectangular inspection frame 5, and the rectangular inspection frame 5 is installed at the center position of the machine body 1. The cardboard body 3 passes through the rectangular inspection frame 5 during the conveying process to realize the inspection operation. With the operation of the conveyor belt 2, the cardboard body 3 can be conveyed until the cardboard body 3 passes through the rectangular inspection frame 5 to realize the inspection operation. The conveyor belt 2 is an existing device driven by a separate motor;

[0035] In the embodiment of the present invention, reference Figure 1-Figure 5, arc-shaped limit frames 7 are slidably installed on both sides of the top surface of the machine body 1, and the arc-shaped limit frame 7 is rotatably connected to a plurality of limit protection rollers 8 on one side close to the cardboard body 3, which is used to limit the cardboard body 3. The arc-shaped limit frame 7 can adjust the position according to the cardboard body 3 of different sizes, so that the limit protection rollers 8 are in contact with the side edges of the cardboard body 3. During the conveying process, the cardboard body 3 can be limited as it contacts with the plurality of limit protection rollers 8, so that the cardboard body 3 is always located in the middle position above the conveyor belt 2 for conveying, thereby ensuring the subsequent detection effect;

[0036] In the embodiment of the present invention, reference Figure 1-Figure 5 , an inner lining plate 301 is provided inside the cardboard body 3, and the inner lining plate 301 divides the inside of the cardboard body 3 into a plurality of holes, an arc-shaped transmission block 11 is slidably installed inside the arc-shaped limit frame 7, and a plurality of limit plugs 15 are rotatably installed on the side of the arc-shaped transmission block 11 close to the cardboard body 3, and a conical plug 1502 is installed at the end of the limit plug 15 for inserting into the corresponding hole to open it, and a negative pressure device 10 is installed above the arc-shaped limit frame 7, and the negative pressure device 10 is connected with the conical plug 1502, and a plurality of inflation holes 1504 are opened inside the conical plug 1502. During the transportation process of the cardboard body 3, as the reciprocating conical plug 1502 is inserted into the corresponding hole, the hole squeezed during the transportation process can be expanded, and then as the negative pressure device 10 is running, the hole can be inflated through the plurality of inflation holes 1504, so that the compressed part of the cardboard body 3 is propped up, which ensures the production quality of the cardboard body 3 on the one hand, and improves the subsequent detection effect at the same time;

[0037] Specifically, the length of the hole inside the cardboard body 3 is generally equal to the width of the cardboard body 3. When the conical plugs 1502 on both sides are inserted into the corresponding holes for inflation, the concave part of the cardboard body 3 can be compressed and stretched;

[0038] Specifically, the negative pressure device 10 is an existing device, and the control operation is realized based on the existing PLC module. When the tapered plug 1502 is inserted into the corresponding hole during operation, the negative pressure device 10 is operated to realize the inflation process;

[0039] In the embodiment of the present invention, specifically, refer to Figure 8A transmission assembly is provided between the arc transmission block 11 and the corresponding limiting protection roller 8, which is used to drive the arc transmission block 11 to reciprocate inside the arc limiting frame 7. A sliding shaft 1101 is fixed to the outside of the arc transmission block 11. The sliding shaft 1101 passes through the arc limiting frame 7 and a reset spring 1102 is sleeved at its end to drive the arc transmission block 11 to reset. As the cardboard body 3 fits with the limiting protection roller 8 during the conveying process, the limiting protection roller 8 can be driven to run, thereby driving the arc transmission block 11 to reciprocate inside the arc limiting frame 7 to achieve the insertion operation of the tapered plug 1502.

[0040] In the embodiment of the present invention, specifically, refer to Figure 8 The transmission assembly includes a driving shaft 13, and a driving gear 1301 is fixedly sleeved at the end of the driving shaft 13. One side of the driving gear 1301 is open. The open driving gear 1301 is a gear with one side lacking teeth, which is used to enable the arc-shaped transmission block 11 to perform a reset operation. When the driving shaft 13 drives the driving gear 1301 to rotate, as the opening position rotates to the transmission tooth plate 12, the limit of the transmission tooth plate 12 can be cancelled, so that the transmission tooth plate 12 can be reset by the combination of the sliding shaft 1101 and the reset spring 1102. The arc transmission block 11 is reset to realize reciprocating operation. A transmission tooth plate 12 is fixed on the side of the arc transmission block 11. The driving gear 1301 meshes with the transmission tooth plate 12. A transmission shaft 801 is fixed on the end of the limit protection roller 8. A transmission belt 802 is rotatably connected between the transmission shaft 801 and the driving shaft 13.
