[0026] Embodiment 1:

[0027] Carton board processing refers to the processing of cardboard by cutting, folding, punching, gluing, etc. to make cartons of various shapes and sizes. During the processing, the cardboard is first cut into the required shape and size by cutting and punching, and then the part that needs to be glued is glued. The glued carton board needs to be folded and pressed to press the glued parts together to ensure that the glue is fully bonded and fixes the shape of the carton board. The carton board processed in this way is convenient for transportation and storage, and can be further used for packaging goods, transporting goods, etc.

[0028] In the traditional method, carton boards are usually folded manually so that the carton boards are bent and adhered to the area coated with glue. Then, the adhesion of the carton boards is strengthened by pressing. This processing method has the problems of low efficiency and slow production speed. Therefore, this embodiment provides a carton board adhesion and pressing device to achieve both folding the carton boards and pressing the carton boards after folding, thereby improving the folding and pressing efficiency of the carton boards, and improving the problems of low efficiency and slow production speed of manual folding and pressing of carton boards.

[0029] like Figure 1-3As shown, the utility model provides a carton board adhesion and pressing device, including a conveyor belt 1; the conveyor belt 1 is a conveyor belt 1 in the prior art, that is, it includes a belt body, a servo motor 2, a roller and a support frame 12, etc.; the servo motor 2 installed on the support frame 12 can drive the roller to rotate, so that the belt body conveys the carton board 17; folding components are provided on both sides of the conveyor belt 1; each folding component includes a moving seat 3 and a moving rod 6; a plurality of moving seats 3 can be fixedly connected to the support frame 12 by bolt connection or welding, and the moving rod 6 is connected to the moving seat 3, and the moving rod 6 is located above the conveyor belt 1, and a plurality of moving seats 3 are evenly arranged along the conveying direction of the conveyor belt 1, and a guide soft rod is connected between any two adjacent moving rods 6; the guide soft rod is located directly above the conveyor belt 1, and the guide soft rod gradually moves away from the moving seat 3 along the conveying direction of the conveyor belt 1;

[0030] The distance between the guide soft rod and the conveyor belt 1 increases first and then decreases along the conveying direction of the conveyor belt 1;

[0031] Wherein, the distance between the guide soft rod and the conveyor belt 1 in one folding assembly is smaller than the distance between the guide soft rod and the conveyor belt 1 in another folding assembly;

[0032] Each guide rod gradually moves from the edge of the conveyor belt 1 to the center of the conveyor belt 1, so that the two folded paperboards 18 of the carton board 17 are folded along the crease from the flat state under the drive of the belt body of the conveyor belt 1;

[0033] Specifically, in the same folding component, the moving rod 6 is made of metal, and the end of the moving rod 6 away from the moving seat 3 is fixedly connected to the same guide soft rod by hot melt adhesive bonding. A layer of hot melt adhesive is applied on the surface of the moving rod 6 using a hot melt adhesive gun, and then the guide soft rod is pressed onto the hot melt adhesive coating. The hot melt adhesive will quickly solidify after cooling, and the guide soft rod will be firmly bonded to the moving rod 6. The guide soft rod is made of plastic and can be deformed. The material of the guide soft rod can be polyurethane (PU), polyethylene (PE) or polypropylene (PP).

[0034] The principle and effect of the above scheme:

[0035] Place the carton board 17 flat on the conveyor belt 1, so that the two folded paperboards 18 of the carton board 17 are respectively placed on the guide soft rods. When the carton board 17 is driven to move by the belt body, the distance between the guide soft rod and the conveyor belt 1 increases first and then decreases along the conveying direction of the conveyor belt 1. When the folded paperboard 18 moves along the guide soft rod, it can bend along the crease, so that the folded paperboard 18 gradually tilts from the initial flat state. When it reaches the highest position of the guide soft rod, the folded paperboard 18 will become a vertical state. At this time, the folded paperboard 18 continues to move along the guide soft rod with a lowered height position. The folded paperboard 18 will deflect toward the inner side of the carton board 17 along the crease and fold on the carton board 17. The folded paperboard 18 will adhere to the glued area 19 on the carton board 17;

[0036] As the guide rod gradually approaches from the edge of the conveyor belt 1 to the center of the conveyor belt 1, the positional relationship between the guide rod and the folding cardboard 18 will change during the movement of the carton board 17 along the guide rod. The guide rod is initially located below the folding cardboard 18. When the folding cardboard 18 is in a vertical state, the guide rod is located outside the folding cardboard 18. When the folding cardboard 18 is folded and adhered to the gluing area 19, the distance between the guide rod and the conveyor belt 1 increases first and then decreases along the conveying direction of the conveyor belt 1. At this time, the guide rod is located above the folding cardboard 18 and can The folded cardboard 18 can be pressed against the gluing area 19, and then driven by the conveyor belt 1, when passing through the guide soft rod and the conveyor belt 1 above the folded cardboard 18, the folded cardboard 18 can be more closely attached to the gluing area 19 of the carton board 17, so that the pressing effect on the folded cardboard 18 can be achieved; in this way, the carton board 17 can be folded and pressed after the crease, which is more efficient and faster than the manual method; at the same time, the thickness of the folded carton board 17 can be reduced, reducing the space occupied in the height direction;

[0037] At the same time, since the distance between the guide soft rod and the conveyor belt 1 in one folding component is smaller than the distance between the guide soft rod and the conveyor belt 1 in the other folding component, the two folding cardboards 18 on the carton board 17 are folded and adhered to the glue coating area 19 on the carton board 17 at different times, so that the folding of the folding cardboards 18 has a sequence, so that one of the folding cardboards 18 is folded on the carton board 17 first, and the other folding cardboard 18 is folded later and can be placed on the previous folding cardboard 18, so that the two folding cardboards 18 on the carton board 17 can be stacked on the carton board 17 in sequence.

[0038] In this embodiment, a horizontally arranged rotating hole is opened at the top of each movable seat 3; the rotating holes are arranged in a direction parallel to the belt body; a cylindrical rotating end is coaxially rotatably connected in each rotating hole; each movable seat 3 is strip-shaped, and the top of the movable seat 3 extends above the support frame 12; a first fastening hole 4 connected to the rotating hole is opened on the vertical side of each movable seat 3; a first fastener 4 is threadedly connected in the first fastening hole; one end of the first fastener 4 extends into the rotating hole and presses against the rotating end; the first fastener 4 is a screw;

[0039] One end of each rotating end is fixedly connected to a rotating seat 5 located outside the rotating hole; the rotating seat 5 is block-shaped; a moving hole is provided on the side wall of the rotating seat 5 away from the belt body; a moving rod 6 is slidably connected in the moving hole; a second fastening hole connected to the moving hole is provided on the side wall of the rotating seat 5; a second fastener 7 is threadedly connected in the second fastening hole; one end of the second fastener 7 extends into the second fastening hole and presses against the moving rod 6; the second fastener 7 is a screw.

[0040] The principle and beneficial effects of the above technical solution:

[0041] By loosening the first fastener 4, the movable seat 3 can be rotated around the rotating end, so as to adjust the direction of the movable seat 3, so as to adjust the direction of the movable rod 6, and then tighten the first fastener 4, and then loosen the second fastener 7, slide the movable rod 6 in the movable hole, so as to adjust the relative distance between the movable rod 6 and the conveyor belt 1, and then tighten the second fastener 7 so that the second fastener 7 is pressed against the movable rod 6, and the position adjustment of the movable rod 6 is completed, and then the guide soft rod is fixed to the end of the movable rod 6 away from the rotating seat 5;

[0042] The angle of the rotating seat 5 can be adjusted by the first fastener 4, and the angle of the moving rod 6 can be adjusted, so that the guide soft rod connected to the moving rod 6 can adjust the height distance from the conveyor belt 1 as needed.

[0043] Embodiment 2:

[0044] This embodiment is based on Example 1. Figure 1-3 As shown, the connection methods of the guide soft rod and the moving rod 6 are different. Specifically, the end of the moving rod 6 away from the moving seat 3 is fixedly connected with a fixing ring 8 by welding; the fixing ring 8 and the moving rod 6 are both made of stainless steel; the axis of the fixing ring 8 extends along the conveying direction of the conveyor belt 1; the guide soft rods in the same folding component are all inserted into the fixing ring 8.

[0045] After adjusting the position of the movable rod 6 in the above manner, the guide flexible rod is passed through the fixing ring 8 in sequence to complete the fixation of the guide flexible rod. Compared with the fixed connection between the guide flexible rod and the movable rod 6 in Example 1, this method is convenient for disassembly and replacement of the guide flexible rod.

[0046] In this embodiment, Figure 1-3 As shown, a fixing hole is provided on the outer wall of the fixing ring 8; the fixing hole extends radially along the fixing ring 8; a third fastener 9 is threadedly connected to the fixing hole; one end of the third fastener 9 extends into the fixing ring 8, and one end of the third fastener 9 is tightly pressed against the guide soft rod; the third fastener 9 is a screw; the third fastener 9 and the moving rod 6 are located on the same side.

[0047] Since the folded cardboard 18 of the carton board 17 rests on the guide rod during the movement, this may drive the guide rod to move under the action of friction. Screwing the third fastener 9 into the fixing hole can make it press against the guide rod, which can improve the stability of the guide rod on the fixing ring 8, thereby avoiding this situation.

[0048] Embodiment three:

[0049] This embodiment is based on the above embodiment. Figure 1 As shown, the conveyor belt 1 includes two rotating rollers 10, a conveyor belt 11, a power piece and two support frames 12; the two support frames 12 are arranged in parallel; the two rotating rollers 10 are evenly arranged between the two support frames 12 in the horizontal direction; the two ends of each rotating roller 10 are rotatably connected to the corresponding two support frames 12 respectively; the rotating roller 10 is perpendicular to the two support frames 12; the conveyor belt 11 is wound around the rotating roller 10; the power piece is fixedly connected to one of the support frames 12; the rotating end of the power piece rotates through the support frame 12, and the rotating end of the power piece is connected to one end of one of the rotating rollers 10 through a coupling; the power piece is a servo motor 2, and the servo motor 2 can accurately control the speed, position and torque, and has a high degree of accuracy and reliability; the rotating end of the power piece is used to drive the rotating roller 10 to rotate, so that the conveyor belt 11 is used to transport the carton board 17.

[0050] The carton board 17 is placed on the conveyor belt 11 so that the movable cardboard of the carton board 17 is placed on the guide soft rod, and the rotating roller 10 is driven to rotate by the rotating end of the power part, thereby driving the conveyor belt 11 to transport the carton board 17 to the other side.

[0051] Embodiment 4:

[0052] This embodiment is based on the third embodiment. Figure 1 , 2 As shown, an adjustment component is arranged on the outer side of the support frame 12; each adjustment component includes a fixed seat 13 and an adjustment rod 14; the adjustment rod 14 is relatively arranged on the outer side of the support frame 12; the fixed seat 13 is fixed to the vertical side wall of the support frame 12 by welding; the adjustment rod 14 is fixed on the fixed seat 13; the adjustment rod 14 is horizontally arranged in a direction parallel to the conveying direction; the movable seat 3 located on one side of the conveyor belt 11 is slidably mounted on the adjustment rod 14.

[0053] Since the movable seat 3 is slidably mounted on the horizontally arranged adjusting rod 14, the relative position between the movable seats 3 can be adjusted, thereby adjusting the distance between adjacent adjusting rods 14, and further adjusting the degree of inclination of the guide soft rod first rising and then lowering. The greater the degree of inclination, the faster the process of the folding cardboard 18 changing from a flat state to a vertical state, and the faster the process of changing from a vertical state to a folded carton board 17, thereby improving the folding efficiency of the folding cardboard 18.

[0054] In this embodiment, Figure 1 , 2 As shown, the movable seat 3 is provided with a positioning hole arranged along the radial direction of the adjusting rod 14; a fourth fastener 15 is threadedly connected to the inner thread of the positioning hole; one end of the fourth fastener 15 is pressed against the adjusting rod 14 to limit the sliding of the movable seat 3 on the adjusting rod 14; the fourth fastener 15 is a screw; since the movable seat 3 is slidably sleeved on the adjusting rod 14, when the movable seat 3 slides to the predetermined position on the adjusting rod 14, the movable seat 3 lacks the fixation with the adjusting rod 14, and the movable seat 3 will rotate around the axis of the adjusting rod 14. By tightening the fourth fastener 15, the adjusting rod 14 can be pressed against to limit the rotation of the movable seat 3, and then the movable seat 3 can be adjusted to the predetermined position and be in a stable state, which can prevent the carton board 17 from pushing the movable seat 3 to rotate under the drive of the conveyor belt 11, which ensures the stability of the carton board 17 during transportation and helps to maintain the normal operation of the production line;

[0055] There are two fixing seats 13; the two fixing seats 13 are respectively installed at the two ends of the adjusting rod 14; each fixing seat 13 is welded to the support frame 12; the fixing seat 13 is provided with horizontally arranged mounting holes; the two ends of the adjusting rod 14 are inserted into the corresponding mounting holes; the fixing seat 13 is provided with a tightening hole connected to the mounting hole; the tightening hole is threadedly connected with a fifth fastener 16; one end of the fifth fastener 16 extends into the mounting hole and tightens the adjusting rod 14; the fifth fastener 16 is a screw; after the adjusting rod 14 is inserted into the mounting hole, the movement of the adjusting rod 14 can be limited by the fifth fastener 16, thereby improving the stability of the adjusting rod 14. At the same time, loosening the fifth fastener 16 facilitates the disassembly of the adjusting rod 14.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
