In order to achieve the above purposes, the technical scheme adopted by the application is as follows:
a full-automatic cover folding and box sealing machine comprises:
a rack assembly;
the folding assembly is arranged at the front part of the rack assembly and comprises a paging part, a front folding part, a rear folding part and two side folding parts, the paging part is arranged at the front part of the folding assembly, and paging plates are arranged at the left side and the right side of the paging part and are suitable for limiting the angle between the left side wing and the right side wing of the carton; the front folding part and the rear folding part are arranged in the middle of the folding assembly, the front folding part and the rear folding part comprise a front folding mechanism and a rear folding mechanism, the front folding mechanism is arranged at the rear end of the front folding part and the rear folding mechanism, the front folding mechanism is suitable for folding the front side wing of the carton, the rear folding mechanism is rotatably connected to the front folding part and the rear folding part, and the rear folding mechanism is suitable for overturning the rear side wing of the carton; the two-side folding part is arranged at the rear part of the folding assembly, and two-side folding mechanisms are arranged at the left side and the right side of the two-side folding part in a rotatable manner and are suitable for overturning the left side wing and the right side wing of the carton;

the glue sealing assembly is installed at the rear part of the folding assembly, glue sealers are arranged on the upper side and the lower side of the glue sealing assembly, and the glue sealers are suitable for sealing adhesive tapes on the upper surface and the lower surface of the carton.
The paging part is additionally arranged on the folding assembly, the angle between the left side wing and the right side wing of the carton can be effectively limited, the angle between the left side wing and the right side wing of the carton of a common conventional carton sealing machine is generally not limited, the repetition of the folding position of the subsequent side wing of the carton is usually ensured by depending on the shape of the carton and the prior crease, but in practical use, because the materials of the cartons in each batch are slightly different, the prior crease can have different degrees of deviation, the repetition precision is ensured only by depending on the manufacturing process of the carton, a larger angle difference can be caused between the left side wing and the right side wing of the carton of different cartons, in the subsequent folding process, the deviation can easily occur between the left side wing and the right side wing of the carton, and the problem of low finished product rate of the cartons is caused.
The gluing component is necessary, because the gluing component can increase the primary positioning of the left side wing and the right side wing of the carton and the front side wing and the rear side wing of the carton, the sealing force provided by the tape sealing is limited, and in the actual production, if the heavy object carried in the carton is heavy, the bearing force of the carton is difficult to ensure by only one light and thin tape, and the problem that the bottom of the carton is exposed in the middle of the use process is difficult to ensure; in the production process, the problem that the glue sealing effect is poor due to the fact that the glue coating assembly is additionally arranged between the front folding portion and the back folding portion and the two side folding portions can be roughly positioned relative to the left side wing and the right side wing of the carton so as to ensure that the relative positions of the left side wing and the right side wing of the carton are fixed before the carton enters the glue sealing assembly is found, if the side wings of the carton are not limited before the glue sealing assembly starts to perform glue sealing operation on the carton, the anti-interference capacity is weak, and deviation is easy to occur among the side wings, so that the glue sealing position of the glue sealing assembly is not uniform. The glue sealing assembly can simultaneously carry out glue sealing operation on the upper surface and the lower surface of the carton so as to reduce repeated operation and improve the glue sealing efficiency of the carton.
Preferably, the front end of the frame assembly is provided with a bottom driving belt assembly, the bottom driving belt assembly comprises a first driving belt, and the upper surface of the first driving belt is in contact with the lower surface of the carton; two side driving belt assemblies are arranged on the left side and the right side of the rack assembly and comprise second driving belts, and the side surfaces of the second driving belts are in contact with the side surfaces of the cartons; an upper driving belt assembly is arranged on the glue sealing assembly and comprises a fourth driving belt, and the bottom surface of the fourth driving belt is in contact with the upper surface of the carton.
Considering production efficiency and interference resistance, on the premise that the yield can be guaranteed, the moving speed of the carton in the carton sealing machine is as fast as possible, therefore, the bottom driving belt component is set to be used for driving the carton to enter the folding component, in the glue sealing component, the carton and the high-speed running carton for coping with heavy load cannot slide relatively in the glue sealing component, and therefore position deviation is caused, the two side driving belt components and the upper driving belt component are set to drive the carton to move, the efficiency is considered, and meanwhile, the carton is prevented from sliding.
Another preferred mode is that the rear folding mechanism includes a rear folding link, a rear folding plate, and a first driving portion, one end of the rear folding link is rotatably connected to the first driving portion, the other end of the rear folding link is connected to the rear folding plate, a middle portion of the rear folding link is rotatably connected to the front and rear folding portions, and the rear folding plate is adapted to turn over the rear side flap of the carton.

The full-automatic carton sealing machine is common automatic equipment and is mainly used for automatically folding and sealing all side wings on the upper surface of a carton 6, and in the actual use process, the problems that the production efficiency is low, the yield is low, the carton sealing adhesive tape of the carton 6 is not adhered to the middle of the left side wing 61 and the right side wing 62 of the carton, gaps among all the side wings are large and the like easily occur.
The position of the left carton side flap 61, the right carton side flap 62, the front carton side flap 63 and the rear carton side flap 64 of the conventional carton 6 is shown in fig. 2.
The inventor further researches and discovers that the existing carton sealing machine does not make targeted design and improvement on heavy loads and cartons 6 of different batches, and the problems of poor repeatability precision, large relative sliding, low yield and the like easily occur because the positioning between the side wings of the cartons 6 is not accurate only by folding and sealing the cartons 6 by the creases produced by the cartons 6.
The inventor therefore developed a fully automatic flap box sealer, one embodiment of which is shown in fig. 1 to 13, comprising:
a rack assembly 1;
a folding assembly 2 installed at the front of the frame assembly 1, the folding assembly 2 including a separation section 21, a front and rear folding section 22 and a side folding section 23, the separation section 21 being installed at the front of the folding assembly 2, separation plates 212 being provided at left and right sides of the separation section 21, the separation plates 212 being adapted to limit an angle between the left side flap 61 and the right side flap 62 of the carton; the front and rear folding portions 22 are installed in the middle of the folding assembly 2, the front and rear folding portions 22 include a front folding mechanism 221 and a rear folding mechanism 222, the front folding mechanism 221 is installed at the rear end of the front and rear folding portions 22, the front folding mechanism 221 is adapted to fold the front side flap 63 of the carton, the rear folding mechanism 222 is rotatably connected to the front and rear folding portions 22, and the rear folding mechanism 222 is adapted to turn the rear side flap 64 of the carton.
As shown in fig. 10, the carton is first folded over the carton front side flap 63 and the carton back side flap 64, then glue is applied to the carton front side flap 63 and the carton back side flap 64, then the carton left side flap 61 and the carton right side flap 62 are folded over, and finally the tape is adhered by the taping assembly.
Fig. 11 is a top view of the box folding machine, the sealing adhesive assembly 4 comprises an upper driving belt assembly 42 and a lower driving belt assembly 44, the position and structure of the upper driving belt assembly 42 are shown in fig. 1, the front view of the lower driving belt assembly 44 is shown in fig. 12, and the top view of the lower driving belt assembly 44 is shown in fig. 13.
In actual production, the paper box 6 firstly passes through the separating section 21 to keep a certain angle between the left paper box side flap 61 and the right paper box side flap 62, then the paper box enters the front and rear folding sections 22, the front paper box side flap 63 touches the front folding mechanism 221 to be folded, and the rear folding mechanism 222 is in an initial state as shown in a solid line part in fig. 1 and 9, and after the paper box 6 enters a proper position, the front paper box side flap enters a broken line part from the solid line part to touch the rear paper box side flap 64, so that the rear paper box side flap 64 is folded, and thus the folding process of the front paper box side flap 63 and the rear paper box side flap 64 is completed in the front and rear paper box folding sections 22.
The two-side folding part 23 is arranged at the rear part of the folding assembly 2, two-side folding mechanisms 232 are rotatably arranged at the left side and the right side of the two-side folding part 23, and the two-side folding mechanisms 232 are suitable for turning the left side wing 61 of the carton and the right side wing 62 of the carton;
a gluing assembly 3 installed between the front and rear hinges 22 and the side hinges 23, the gluing assembly 3 being adapted to spray hot melt glue on the front carton side flap 63 and the rear carton side flap 64;
the glue sealing assembly 4 is installed at the rear part of the folding assembly 2, glue sealing devices 41 are arranged on the upper side and the lower side of the glue sealing assembly 4, the glue sealing devices 41 are suitable for sealing adhesive tapes on the upper surface and the lower surface of the carton 6, wherein the glue sealing devices 41 are in the prior art, and the gluing, pressing and glue breaking of the adhesive tapes on the surface of the carton 6 are realized by utilizing springs, connecting rods and rollers.
The paging part 21 is additionally arranged on the folding assembly 2, so that the angle between the left side wing 61 of the carton and the right side wing 62 of the carton can be effectively limited, the angle between the left side wing 61 of the carton and the right side wing 62 of the carton of a conventional carton sealing machine is generally not limited, the repetition of the folding position of the side wing of the subsequent carton 6 is usually ensured by the shape of the carton 6 and the prior crease, but in practical use, because the material of the carton 6 in each batch is slightly different, the prior crease has different deviation in different degrees, the repetition precision is ensured only by the manufacturing process of the carton 6, a larger angle difference exists between the left side wing 61 of the carton and the right side wing 62 of the carton 6, and in the subsequent folding process, the deviation easily occurs between the left side wing 61 of the carton and the right side wing 62 of the carton, so that the yield of the carton 6 is low.
The gluing component 3 is necessary because the gluing component 3 can increase the primary positioning of the left side wing 61 and the right side wing 62 of the carton and the front side wing 63 and the rear side wing 64 of the carton, and because the sealing force provided by the tape sealing is limited, and in the actual production, if the heavy object carried in the carton 6 is heavy, the bearing capacity of the carton 6 is difficult to ensure by only one light and thin tape, and the problem that the bottom of the carton 6 is exposed in the middle of the use process is more difficult to ensure; in the production process, it is found that if the side wings of the carton 6 are not limited before the glue sealing assembly 4 starts to perform glue sealing operation on the carton 6, the anti-interference capability is weak, and the side wings are prone to deviation, so that the glue sealing position of the glue sealing assembly 4 is not uniform, and the glue sealing effect is poor, therefore, the glue sealing assembly 3 is additionally arranged between the front folding part 22 and the back folding part 23, and the relative positions of the left side wing 61 of the carton and the right side wing 62 of the carton can be roughly positioned, so that the relative positions of the left side wing 61 of the carton and the right side wing 62 of the carton are fixed before entering the glue sealing assembly 4. The glue sealing assembly 4 can simultaneously perform glue sealing operation on the upper surface and the lower surface of the carton 6 so as to reduce repeated operation and improve the glue sealing efficiency of the carton 6.

The length of the rear folding link 2221 is required to be adjustable, and in the actual production process, for the cartons 6 with different sizes, if the length of the rear folding link 2221 cannot be adjusted, for the taller cartons 6, the contact area between the carton rear side wings 64 and the rear folding plates 2222 is too large, and the cartons 6 are easily damaged; for a shorter carton 6, the contact area between the rear side flap 64 of the carton and the rear folding plate 2222 is too small, so that the rear side flap 64 of the carton is not folded, and thus different rear folding links 2221 are adjusted according to different cartons 6, thereby increasing the overall flexibility of the mechanism, reducing the use cost and improving the product competitiveness.
Alternatively, as shown in fig. 6 and 7, the side folding portion 23 includes a side folding base 231 and a second driving portion 233, in this specific embodiment, the second driving portion 233 is an air cylinder, the side folding mechanism 232 is mounted on the side folding base 231, the side folding mechanism 232 includes a side folding link 2321 and a side folding plate 2322, one end of the side folding link 2321 is rotatably connected to the second driving portion 233, the other end of the side folding link 2321 is connected to the side folding plate 2322, and a middle portion of the side folding link 2321 is rotatably connected to the side folding base 231.
The second driving portion 233 can push the two-side folding connecting rods 2321 to rotate, so that the two-side folding connecting rods 2321 drive the two-side folding plates 2322 to rotate, and thus drive the left carton flank 61 and the right carton flank 62 to rotate relatively, thereby achieving the purpose of folding the left carton flank 61 and the right carton flank 62, and the design of the two-side folding connecting rods 2321 can ensure the stability of the operation of the carton sealing machine.
