Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a carton processing folding device. Background Art

[0002] In the process of carton production, the carton is first produced into sheets, and then a cutting device is used to cut the carton into a specific size. Subsequently, a folding device is used to indent and fold the surface of the carton, so as to facilitate the carton to be folded into the target box shape at a later time. Most of the existing carton folding devices form indentations on the surface of the carton by means of a pressing wheel. The carton sheet is then conveyed on a conveyor belt. When passing under the pressing wheel, the pressing wheel exerts pressure on the surface of the carton, causing folding indentations on the surface of the carton. The deficiency of the prior art is that during the indentation process of the existing carton sheet, the carton sheet is between the pressing wheel and the conveyor belt. The conveyor belt is generally made of rubber, resulting in shallow marks when the pressing wheel indents. Based on the above situation, it is necessary to design a carton processing folding device to solve the above problem. Utility Model Content

[0003] The utility model provides a carton processing folding device to solve the problem that when a pressing wheel is used to indent a carton in the prior art, the marks are relatively shallow.

[0004] The technical problem solved by the utility model is achieved by the following technical solutions:

[0005] A carton processing folding device comprises a main conveyor belt arranged on a frame and two auxiliary conveyor belts arranged above the main conveyor belt, an indentation assembly is arranged between the two auxiliary conveyor belts, the indentation assembly comprises a rod body installed on the frame and a pressure wheel rotatably connected to the outside of the rod body, a gap is preset on the main conveyor belt, the pressure wheel is located above the gap, a rotating roller is also arranged on the frame, the rotating roller is located below the rod body, a round convex is arranged on the rotating roller, and the round convex is located directly below the pressure wheel.

[0006] Preferably, the rod body is connected to the frame via an adjustment assembly.

[0007] Preferably, the adjustment assembly includes a guide rod fixed on the frame, a connecting block fixed on the end of the guide rod, a screw threadedly connected to the connecting block, and a spring sleeved on the outside of the guide rod for supporting the rod body, and both ends of the rod body are movably sleeved on the guide rod.

[0008] Preferably, the pressing wheel and the round convex portion are both made of hard material.

[0009] Preferably, the distance between the pressing wheel and the round convexity is smaller than the thickness of the carton sheet.

[0010] Preferably, the main conveyor belt and the auxiliary conveyor belt have the same linear speed, and the main conveyor belt and the auxiliary conveyor belt have the same conveying direction for the carton sheets.

[0011] The beneficial effect of the utility model is that by arranging a rotating roller and a convex cooperating pressing wheel to indent the carton, the indentation effect of the carton can be better, and at the same time, an adjustment component is arranged to adjust the height of the pressing wheel up and down to adjust the indentation pressure of the pressing wheel on the carton.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0020] Reference Figure 1-Figure 5As shown, a carton processing folding device includes a main conveyor belt 1 arranged on a frame 4 and two auxiliary conveyor belts 2 arranged above the main conveyor belt 1, an indentation assembly 3 is arranged between the two auxiliary conveyor belts 2, the indentation assembly 3 includes a rod body 301 installed on the frame 4 and a pressure wheel 302 rotatably connected to the outside of the rod body 301, a gap 101 is preset on the main conveyor belt 1, and the pressure wheel 302 is located above the gap 101, and a rotating roller 5 is also arranged on the frame 4, and the rotating roller 5 is located below the rod body 301, and a round convex 6 is arranged on the rotating roller 5, and the round convex 6 is located directly below the pressure wheel 302.

[0021] Among them, the existing folding device includes a main conveyor belt 1 and two auxiliary conveyor belts 2. The carton sheet 7 is conveyed by clamping between the auxiliary conveyor belt 2 and the main conveyor belt 1. An indentation component 3 with a pressure wheel 302 is arranged between the two auxiliary conveyor belts 2. When the carton sheet 7 is conveyed to the bottom of the indentation component 3, the pressure wheel 302 indents the surface of the carton sheet 7. During the indentation process, the main conveyor belt 1 is below the carton sheet 7. Since the main conveyor belt 1 is often made of rubber, it is easy to deform under pressure, so the indentation is unclear. Based on the deficiencies of the prior art, the utility model sets a gap 101 on the main conveyor belt 1 and a rotating roller 5 on the frame 4. The rotating roller 5 is provided with a round bulge 6 in the gap 101. When the main conveyor belt 1 and the auxiliary conveyor belt 2 convey the carton sheet 7 to between the pressure wheel 302 and the round bulge 6, the carton sheet 7 is subjected to the action of the pressure wheel 302 and the round bulge 6 to form an indentation.

[0022] Further, such as Figure 1 , Figure 4 and Figure 5 As shown, the rod body 301 is connected to the frame 4 through an adjustment assembly.

[0023] Among them, by setting an adjustment component, the position of the pressing wheel 302 can be adjusted up and down, so that the distance between the pressing wheel 302 and the round protrusion 6 becomes larger or smaller, thereby adjusting the depth of the indentation.

[0024] Furthermore, the adjustment assembly includes a guide rod 303 fixed on the frame 4, a connecting block 305 fixed on the end of the guide rod 303, a screw 306 threadedly connected to the connecting block 305, and a spring 304 sleeved on the outside of the guide rod 303 for supporting the rod body 301, and both ends of the rod body 301 are movably sleeved on the guide rod 303.

[0025] When adjusting the position of the pressure wheel 302, the screw 306 is first rotated to make the screw 306 move up or down, and the bottom of the screw 306 resists the rod body 301. When the screw 306 moves down, it resists the rod body 301 to move down, and the spring 304 is compressed by the downward movement of the rod body 301. When the screw 306 moves up, the spring 304 extends and drives the rod body 301 to move up and contact the bottom of the screw 306.

[0026] Furthermore, the pressing wheel 302 and the round protrusion 6 are both made of hard materials.

[0027] The hard material can be made of non-elastic materials such as iron or plastic.

[0028] Furthermore, the distance between the pressing wheel 302 and the round protrusion 6 is smaller than the thickness of the carton sheet 7 .

[0029] The distance between the pressing wheel 302 and the round protrusion 6 is smaller than the thickness of the carton sheet 7 , so that the carton sheet 7 can be indented smoothly.

[0030] Furthermore, the main conveyor belt 1 and the auxiliary conveyor belt 2 have the same linear speed, and the main conveyor belt 1 and the auxiliary conveyor belt 2 convey the carton sheets 7 in the same direction.

[0031] Among them, the main conveyor belt 1 and the auxiliary conveyor belt 2 have the same linear speed and the same conveying direction for the carton sheet 7, which can enable the carton sheet 7 to be conveyed smoothly. The main conveyor belt 1 and the auxiliary conveyor belt 2 clamp and convey the carton sheet 7 to ensure that the carton sheet 7 has sufficient friction to be conveyed forward and overcome the resistance generated during indentation.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
