Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Please refer to Figures 1-7, An automatic cardboard production line, including a carrying base 1. On the upper surface of the carrying base 1, there are multiple groups of fixing units 2 for installation and fixation. Each group of fixing units 2 is successively provided with two symmetric dust-removing rollers 3 adapted to the cardboard body 8, two symmetric glue-applying rollers 4, two symmetric guiding rollers 5 for guiding the waterproof film body 9, two pressing rollers 6 for pressing the cardboard body 8 and the waterproof film body 9, and a conveying device 15 for conveying. On the carrying base 1, there are several groups of adjusting units 7 for adjusting the positions of the fixing units 2. The fixing unit 2 includes two first fixing plates 10 adapted to the dust-removing rollers 3, two second fixing plates 11 adapted to the glue-applying rollers 4, two third fixing plates 12 adapted to the guiding rollers 5, two fourth fixing plates 13 adapted to the pressing rollers 6, and two fifth fixing plates 14 adapted to the conveying device 15. The two guiding rollers 5 are rotatably connected between the two third fixing plates 12. The adjusting unit 7 includes sliding blocks 38 respectively fixedly installed at the lower ends of the first fixing plate 10, the second fixing plate 11, the third fixing plate 12, and the fourth fixing plate 13. On the upper surface of the carrying base 1, there are several sliding grooves 37 adapted to the sliding blocks 38. On one side of the carrying base 1, several fourth driving motors 35 are fixedly installed. In each sliding groove 37, there is a bidirectional lead screw 36 whose one end is fixedly connected to the output end of the corresponding fourth driving motor 35. The bidirectional lead screw 36 penetrates through the two sliding blocks 38 and is threadedly connected to the two sliding blocks 38. When the bidirectional lead screw 36 rotates, it drives the two sliding blocks 38 to move towards or away from each other.

[0029] Specifically, at both ends of the carrying base 1, there are a traction device for traction of the cardboard body 8 and a release roller for the waterproof film body 9. The traction device is used to traction the cardboard body 8. When the cardboard body 8 passes through the two dust-removing rollers 3, the two dust-removing rollers 3 remove dust from both sides of the cardboard body 8. The dust-removing roller 3 includes but is not limited to a polyurethane dust-removing roller 3, which has good adhesion and wear resistance and can effectively remove the tiny dust particles on the upper and lower surfaces of the cardboard body 8. The glue-applying roller 4 is used to apply glue to the upper and lower surfaces of the cardboard body 8. The waterproof film body 9 is guided by the guiding rollers 5 to between the two pressing rollers 6. The two pressing rollers 6 press and bond the waterproof film body 9 and the cardboard body 8 to achieve bonding of the waterproof film body 9 on both sides of the cardboard body 8. When it is necessary to install or replace the dust-removing roller 3, the glue-applying roller 4, the guiding roller 5, or the pressing roller 6, by starting the fourth driving motor 35, the output end of the fourth driving motor 35 drives the bidirectional lead screw 36 to rotate. The threads on the side of the bidirectional lead screw 36 are reverse and symmetric. The bidirectional lead screw 36 drives the two sliding blocks 38 to move away from each other in the sliding groove 37, and the two first fixing plates 10, the second fixing plates 11, the third fixing plates 12, or the fourth fixing plates 13 move away from each other, so that the dust-removing roller 3, the glue-applying roller 4, the guiding roller 5, or the pressing roller 6 can be removed and installed or replaced, which is convenient for installing or replacing the dust-removing roller 3, the glue-applying roller 4, the guiding roller 5, or the pressing roller 6.

[0030] As a technical optimization scheme of the utility model, at both ends of the two dust sticking rollers 3, there are first insertion shafts 16 with a polygonal cross-section passing through. The two ends of the first insertion shafts 16 pass through the first fixing plates 10. On the two first fixing plates 10, there is a first rotating ring 17 sleeved on the side of the first insertion shaft 16 rotatably connected. On the sides of the two first rotating rings 17, there are first gears 18 meshing with each other. On one side of one of the first fixing plates 10, there is a first driving motor 19 fixedly installed. The output end of the first driving motor 19 is fixedly connected with a second gear 20 meshing with one of the first gears 18.

[0031] Specifically, when the first driving motor 19 is started, the output end of the first driving motor 19 drives the second gear 20 to rotate. The second gear 20 drives the first gear 18 at the lower position to rotate. The first gear 18 at the lower position drives the first gear 18 at the upper position to rotate. The first gear 18 drives the first rotating ring 17 to rotate. The first rotating ring 17 drives the first insertion shaft 16 to rotate, and then drives the two dust sticking rollers 3 to rotate towards each other, which not only removes dust from the upper and lower surfaces of the cardboard body 8, but also has the effect of conveying the cardboard body 8. When the dust sticking rollers 3 need to be replaced, the two first fixing plates 10 move away from each other, and the two first rotating rings 17 are separated from the first insertion shafts 16, so that the dust sticking rollers 3 can be replaced, which is convenient for installing or replacing the dust sticking rollers 3.

[0032] As a technical optimization scheme of the utility model, at both ends of the two glue applying rollers 4, there are second insertion shafts 22 with a polygonal cross-section passing through and the ends passing through the second fixing plates 11. At both ends of the two second insertion shafts 22, there are second rotating rings 21 sleeved and rotatably connected with the second fixing plates 11. On the sides of the two second rotating rings 21, there are third gears 23 fixedly installed and meshing with each other. On one side of one of the second fixing plates 11, there is a second driving motor 24 fixedly installed. The output end of the second driving motor 24 is fixedly installed with a fourth gear 25 meshing with one of the third gears 23. Between the two second fixing plates 11, there are several glue storage frames 26 adapted to the glue applying rollers 4. One side of the glue storage frame 26 is closely attached to the glue applying roller 4 and there is a glue outlet 33 opened at the lower part of one side. On the opposite sides of the two fourth fixing plates 13, there are mounting plates 34 fixedly installed for mounting the glue storage frames 26.

[0033] Specifically, drive the second drive motor 24. The output end of the second drive motor 24 drives the fourth gear 25 to rotate. The fourth gear 25 drives the lower third gear 23 to rotate. The lower third gear 23 drives the upper third gear 23 to rotate. The third gear 23 drives the second rotating ring 21 to rotate. The second rotating ring 21 drives the second insertion shaft 22 to rotate, thereby driving the two glue application rollers 4 to rotate. The glue storage frame 26 is installed on the corresponding two mounting plates 34 through fasteners. The glue storage frame 26 transports the glue to the inside of the glue storage frame 26 through an external device. The glue flows to the side of the glue application roller 4 through the glue outlet 33. The glue application roller 4 applies the glue to the side of the cardboard body 8. When it is necessary to install or replace the glue application roller 4, the two second fixing plates 11 move away from each other. The second insertion shaft 22 is separated from the second rotating ring 21, and then the glue application roller 4 can be replaced.

[0034] As a technical optimization scheme of the present utility model, third insertion shafts 27 penetrate through the fourth fixing plate 13 at both ends of the two pressing rollers 6. Third rotating rings 28 rotatably connected to the fourth fixing plate 13 are sleeved on the sides of one ends of the two third insertion shafts 27. Fifth gears 29 are fixedly installed on the sides of the two third rotating rings 28. Sixth gears 30 that are meshed with each other and respectively meshed with the two fifth gears 29 are rotatably connected to one side of the fourth fixing plate 13. A third drive motor 31 is fixedly installed on one side of the fourth fixing plate 13. A seventh gear 32 meshed with one of the fifth gears 29 is fixedly installed at the output end of the third drive motor 31.

[0035] Specifically, when starting the third drive motor 31, the output end of the third drive motor 31 drives the seventh gear 32 to rotate. The seventh gear 32 drives the lower fifth gear 29 to rotate. The lower fifth gear 29 drives the lower sixth gear 30 to rotate. The lower sixth gear 30 drives the upper sixth gear 30 to rotate. The upper sixth gear 30 drives the upper fifth gear 29 to rotate. When the fifth gear 29 rotates, it drives the two third rotating rings 28 to rotate. The two third rotating rings 28 drive the two third insertion shafts 27 to rotate. The two third insertion shafts 27 drive the two pressing rollers 6 to rotate. The two pressing rollers 6 rotate towards each other to press and bond the waterproof film body 9 and the already glued cardboard body 8. When it is necessary to replace the pressing roller 6, the two fourth fixing plates 13 move away from each other. After the third insertion shaft 27 is separated from the third rotating ring 28, the pressing roller 6 can be replaced.
