[0004] In the above solution, a pushing component is used to push a push plate to push the cardboard out of the feeding device, resulting in the following disadvantages: when pushing the cardboard to move, the push plate will move horizontally in a reciprocating manner, with a large amplitude of operation, increasing the risk of being pinched and reducing the safety during feeding. Content of the Utility Model

[0005] The purpose of the utility model is to provide an indentation machine to solve the problems that the push plate will move horizontally in a reciprocating manner, with a large amplitude of operation, increasing the risk of being pinched and reducing the safety during feeding.

[0006] To achieve the above utility model purpose, the utility model adopts the following technical solutions: an indentation machine includes an installation groove, a conveyor belt is arranged inside the installation groove, a feeding box is fixed on the top surface of the installation groove, a plurality of fixing grooves are opened on the inner bottom surface of the feeding box, an electric roller is rotatably arranged inside the fixing groove, a discharge port is opened on one side of the inner part of the feeding box, a fixed folding plate is fixed on the top surface of the installation groove, a cylinder is fixed on the top surface of the fixed folding plate, a sliding hole is opened on the top surface of the fixed folding plate, and the telescopic rod of the cylinder is slidably inserted into the sliding hole.

[0007] Preferably, two stabilizing holes are opened on the top surface of the fixed folding plate, two stabilizing columns are fixed on the top surface of the indentation plate, and the stabilizing columns are slidably inserted into the stabilizing holes.

[0008] Preferably, a plurality of sliding grooves are respectively formed on both inner sides of the feeding box. A sliding rod is fixed on one side inside the sliding groove. A sliding plate is slidably arranged on one side of the feeding box. A plurality of movable plates are respectively fixed on both sides of the sliding plate. The movable plates are slidably inserted with the sliding rods. An extrusion spring is wound around the sliding rod. One end of the extrusion spring is fixed to one side inside the sliding groove, and the other end of the extrusion spring is fixed to one side of the movable plate.

[0009] Preferably, a support folding plate is fixed on the top surface of the feeding box. A sleeving hole is formed on the top surface of the support folding plate. A lifting rod is slidably inserted inside the sleeving hole. A pressing plate is fixed to the bottom end of the lifting rod. A pressing spring is wound around the surface of the lifting rod. One end of the pressing spring is fixed to the bottom surface of the support folding plate, and the other end of the pressing spring is fixed to the top surface of the pressing plate.

[0010] Preferably, a vision camera is fixed on one inner side of the fixed folding plate. A PLC controller is arranged on one side of the fixed folding plate. The vision camera is electrically connected to the PLC controller, and the air cylinder is electrically connected to the PLC controller.

[0011] Preferably, support columns are respectively fixed at the four corners of the bottom surface of the installation groove. Anti-slip pads are fixed to the bottom ends of the support columns.

[0012] Compared with the prior art, an indentation machine adopting the above technical scheme has the following beneficial effects:

[0013] First, before indentating the carton, the staff will first put the carton into the feeding box. At this time, the bottom surface of the lowermost carton will contact the surface of the electric roller. Then, the rotating electric roller is used to push the lowermost carton out of the feeding box from the discharge port and fall on the top surface of the conveyor belt. The carton falling on the conveyor belt will be driven by the working conveyor belt to move and finally move to directly below the fixed folding plate. Then, the telescopic rod of the extended air cylinder will push the indentation plate downward and press it on the carton to form an indentation. When pushing the carton to move for feeding, the required movement amplitude is small, reducing the situation of being pinched and increasing the safety of feeding.

[0014] II. Before the cardboard box is placed into the loading box, the staff will first apply a force to the sliding plate, causing the sliding plate to move outward in the loading box and driving the compression spring to stretch. Then, the staff will put the cardboard box into the loading box and remove the force applied to the sliding plate. The sliding plate will be pulled by the extended compression spring and pressed against one side of the cardboard box. As the cardboard box slowly moves out of the loading box, the number and height of the cardboard boxes in the loading box gradually decrease. Since the pressing spring is in a compressed state, as the height of the cardboard box decreases, the pressing spring will apply a downward force to the pressing plate, and thus the pressing plate can apply a downward force to the cardboard box, increasing the firmness of the position of the cardboard box in the loading box;

[0015] III. As the cardboard box moves on the conveyor belt, when the cardboard box moves directly below the fixed folding plate, it will be observed by the vision camera. Then, the vision camera will send the observation information to the PLC controller, and then through the PLC controller to the vision recognition system, and use the vision analysis system to analyze the indentation position of the cardboard box, increasing the accuracy when indentating the cardboard box.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will, with reference to the accompanying drawings, give a detailed description of the preferred embodiments of the present invention.

[0022] Such as Figures 1 - 4As shown in the figure, an indentation machine includes an installation groove 1. Inside the installation groove 1, there is a conveyor belt 2. On the top surface of the installation groove 1, a feeding box 3 is fixed. On the inner bottom surface of the feeding box 3, several fixing grooves 4 are opened. Inside the fixing grooves 4, electric rollers 5 are rotatably arranged. On one side inside the feeding box 3, a discharge port 25 is opened. On the top surface of the installation groove 1, a fixed folding plate 6 is fixed. On the top surface of the fixed folding plate 6, a cylinder 7 is fixed. On the top surface of the fixed folding plate 6, a sliding hole 8 is opened. The telescopic rod of the cylinder 7 is slidably inserted into the sliding hole 8. At the bottom end of the telescopic rod of the cylinder 7, an indentation plate 9 is fixed. On the top surface of the fixed folding plate 6, two stabilizing holes 11 are opened. On the top surface of the indentation plate 9, two stabilizing columns 10 are fixed. The stabilizing columns 10 are slidably inserted into the stabilizing holes 11.

[0023] During use, before indentating the cardboard box, the staff will first put the cardboard box into the feeding box 3. At this time, the bottom surface of the lowermost cardboard box will contact the surface of the electric roller 5. Then, the rotating electric roller 5 is used to push the lowermost cardboard box out of the feeding box 3 from the discharge port 25 and fall onto the top surface of the conveyor belt 2. The cardboard box on the conveyor belt 2 will be driven by the working conveyor belt 2 to move and finally move to directly below the fixed folding plate 6. Then, the extended telescopic rod of the cylinder 7 will push the indentation plate 9 downward and press it on the cardboard box to form an indentation. When pushing the cardboard box to move for feeding, the required movement amplitude is small, reducing the situation of being pinched and increasing the safety of feeding.

[0024] As Figure 2 and Figure 3 As shown in the figure, several sliding grooves 13 are respectively opened on both sides inside the feeding box 3. On one side inside the sliding grooves 13, sliding rods 14 are fixed. On one side of the feeding box 3, a sliding plate 15 is slidably arranged. On both sides of the sliding plate 15, several movable plates 16 are respectively fixed. The movable plates 16 are slidably inserted into the sliding rods 14. An extrusion spring 17 is wound around the sliding rods 14. One end of the extrusion spring 17 is fixed to one side inside the sliding groove 13, and the other end of the extrusion spring 17 is fixed to one side of the movable plate 16. On the top surface of the feeding box 3, a support folding plate 18 is fixed. On the top surface of the support folding plate 18, a sleeving hole 19 is opened. Inside the sleeving hole 19, a lifting rod 20 is slidably inserted. At the bottom end of the lifting rod 20, a pressing plate 22 is fixed. A pressing spring 21 is wound around the surface of the lifting rod 20. One end of the pressing spring 21 is fixed to the bottom surface of the support folding plate 18, and the other end of the pressing spring 21 is fixed to the top surface of the pressing plate 22.

[0025] In use, before the cardboard box is placed into the loading box 3, the staff will first apply a force to the sliding plate 15, causing the sliding plate 15 to move outward in the loading box 3 and driving the compression spring 17 to stretch. Then the staff will put the cardboard box into the loading box 3 and remove the force applied to the sliding plate 15. The sliding plate 15 will be pulled by the extended compression spring 17 and pressed against one side of the cardboard box. As the cardboard box slowly moves out of the loading box 3, the number and height of the cardboard boxes in the loading box 3 gradually decrease. Since the pressing spring 21 is in a compressed state, as the height of the cardboard box decreases, the pressing spring 21 will apply a downward force to the pressing plate 22, and thus the pressing plate 22 can be used to apply a downward force to the cardboard box, increasing the firmness of the position of the cardboard box in the loading box 3.

[0026] As Figure 2 and Figure 4 shown, a vision camera 12 is fixed on the inner side of the fixed folding plate 6, a PLC controller is arranged on one side of the fixed folding plate 6, the vision camera 12 is electrically connected to the PLC controller, the air cylinder 7 is electrically connected to the PLC controller, support columns 23 are respectively fixed at the four corners of the bottom surface of the installation groove 1, and anti-slip pads 24 are fixed at the bottom ends of the support columns 23.

[0027] In use, as the cardboard box moves on the conveyor belt 2, when the cardboard box moves directly below the fixed folding plate 6, it will be observed by the vision camera 12. Then the vision camera 12 will send the observation information to the PLC controller, and then to the vision recognition system through the PLC controller, and the vision analysis system is used to analyze and resolve the indentation position of the cardboard box, increasing the accuracy when indentating the cardboard box.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
