Description

Technical Field

[0001] The invention relates to the technical field of welding wire box packaging, and in particular to an automatic box-packing mechanism. Background Art

[0002] After the larger welding wire is coiled, it is inconvenient to carry it manually due to its large size and heavy weight. Therefore, packaging equipment will be purchased or modified. After the cardboard is sent to the conveyor belt, the welding wire reel is lifted to the box folding device by a crane. Under the action of the automation mechanism, the box folding, packaging and gluing are automatically performed. After the cardboard and welding wire reel come out of the packaging equipment, they are the boxed welding wire products. For small welding wire reels, most of them are folded, packed and glued manually, which is inefficient.

[0003] Since the packaging equipment of large wire reels is more complex and has more sensors, it is difficult to transform large wire reels into small wire reels. Since there are large differences in size and weight between large and small wire reels, mechanisms such as hoisting mechanisms and complex multi-sensor custom automatic delivery mechanisms can be omitted. If the same miniaturized equipment as the large wire reel packaging equipment is customized according to the size of the small wire reel, the cost will be too high.

[0004] In view of this, an automatic boxing mechanism is designed, which can realize the automatic boxing packaging of small welding wire reels with simple cooperation of workers and improve the boxing packaging efficiency. Summary of the invention

[0033] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 11 An automatic box-setting mechanism includes a frame 1, a controller, a lifting and lowering box-pressing mechanism, a first gluing mechanism, a second gluing mechanism, a first conveyor belt 2, a second conveyor belt 4 and a third conveyor belt 10.

[0035] Preferably, the controller adopts an STM32 single chip microcomputer or a SMART200 PLC controller.

[0036] It should be noted that the rack 1 refers to a support structure arranged according to the installation requirements of various mechanisms and components, and its support structure has diverse characteristics. Those skilled in the art can use common structures to connect the support structure of the rack 1 in the present disclosure, and the rack 1 structure given in the accompanying drawings is not unique.

[0037] A folding box mold is fixedly provided on the frame 1, and the folding box mold includes a rectangular frame 14 arranged on the top of the frame 1. Limiting enclosures 15 are fixedly provided above the three edges of the top of the rectangular frame 14, and no enclosure is provided above the remaining edge to form a paper feed 16. The first conveyor belt 2 is arranged next to the frame 1 to convey the cardboard 9 through the paper feed 16 to enter the top of the rectangular frame 14. The first gluing mechanism is arranged next to the first conveyor belt 2 to spray the surface of the cardboard 9 passing through the first conveyor belt 2.

[0038] Specifically, the cardboard 9 includes a box bottom 901, a front box wall 902, a rear box wall 903, a box top 904, a side box wall 905, a side folding portion 906, a side cover portion 907 and a front cover portion 908. The dotted lines of the cardboard 9 in the accompanying drawings are pre-processed folds.

[0039] It should be noted that the first conveyor belt 2 used to transport cardboard 9 is a commonly used device for transporting cardboard 9. The complex one is an automatic board feeding conveyor belt, and the simple one is a manual board feeding conveyor belt. The first conveyor belt 2 in the present disclosure is not limited to an automatic board feeding conveyor belt or a manual board feeding conveyor belt.

[0040] Specifically, the first glue coating mechanism includes a first bracket 6 disposed beside the frame 1, a first glue sprayer 7 and a first sensor 8 are fixedly disposed on the first bracket 6, the first glue sprayer 7 is disposed above the first conveyor belt 2, the first sensor 8 is disposed above the first conveyor belt 2, and the first glue sprayer 7 and the first sensor 8 are both electrically connected to the controller. Preferably, the first glue sprayer 7 is a quick-drying hot melt glue sprayer, and the first sensor 8 is an infrared sensor.

[0041] When the above solution is used, the first sensor 8 is used to detect the cardboard 9 passing on the first conveyor belt 2. When the first sensor 8 detects the cardboard 9, the first glue coating mechanism sprays quick-drying hot melt glue toward the side folding portion 906. The cardboard 9 sprayed on the side folding portion 906 enters the rectangular frame 14 from the paper inlet 16 and reaches the preset position quickly and accurately with the help of the limiting enclosure.

[0042] The folding box mold also includes a mold tube 18 arranged below the rectangular frame 14. The top edge of the mold tube 18 is also fixedly connected to the inner wall of the rectangular frame 14 through a plurality of arc-shaped first guide plates 17. The lifting and lowering box pressure mechanism is fixedly mounted on the frame 1 and arranged above the rectangular frame 14. The lifting and lowering box pressure mechanism is used to push the cardboard 9 to slide downward along the first guide plate 17 into the mold tube 18 to form an unfinished body of a rectangular box with an open upper end and an unobstructed front end.

[0043] Specifically, the molded tube 18 includes a front tube plate 33, a rear tube plate 32, an upper left tube plate 34, a lower left tube plate 36, an upper right tube plate 35 and a lower right tube plate 37 fixedly mounted on the frame 1. The front tube plate 33 is arranged at the front end, the rear tube plate 32 and the front tube plate 33 are arranged at the rear end and are parallel to the front tube plate 33. The upper left tube plate 34 and the lower left tube plate 36 are both arranged at the left end. The lower left tube plate 36 is spaced below the upper left tube plate 34 to form a side opening 38. The lower left tube plate 36 is provided The upper left tube sheet 34 is parallel to the upper left tube sheet 34, the upper right tube sheet 35 and the lower right tube sheet 37 are both arranged at the right end, the lower right tube sheet 37 is arranged below the upper right tube sheet 35 to form a side opening 38, the lower right tube sheet 37 is arranged at the right end of the upper right tube sheet 35 and is parallel to the upper right tube sheet 35, the upper left tube sheet 34 and the upper right tube sheet 35 are parallel to each other, the upper left tube sheet 34 and the front tube sheet 33 are perpendicular to each other, the upper left tube sheet 34, the upper right tube sheet 35, and the front tube sheet The tops of the front and rear tube sheets 33 and 32 are connected to the bottom of the first guide plate 17, the left and right ends of the upper left tube sheet 34 and the upper right tube sheet 35 are not connected to the left and right ends of the front tube sheet 33 and the rear tube sheet 32, and a gap is left. The left and right ends of the lower left tube sheet 36 and the lower right tube sheet 37 are not connected to the left and right ends of the front tube sheet 33 and the rear tube sheet 32, and a gap is left. Two second guide plates 19 and an arc-shaped third guide plate 20 are respectively arranged in the interval between the lower left tube sheet 36 and the upper left tube sheet 34 and in the interval between the lower right tube sheet 37 and the upper right tube sheet 35. The bottoms of the two third guide plates 20 are respectively fixedly connected to the top of the lower left tube sheet 36 and the top of the lower right tube sheet 37. Four second guide plates 19 are fixedly arranged on the frame 1 and arranged above the third guide plates 20. The top of the third guide plate 20 is bent and extended upward in the direction away from the molded tube 18, and the two second guide plates 19 on the same side are arranged in an inverted "eight" shape.

[0044] Specifically, the lifting and lowering pressure box mechanism includes a third bracket 13 fixedly mounted on the frame 1, on which a telescopic cylinder 11 is fixedly mounted, and on which a second bracket 12 is also fixedly mounted for stably mounting the telescopic cylinder 11. The telescopic rod of the telescopic cylinder 11 extends downward and is fixedly connected to a sleeve pressure box 3, which is used to extend downward into the mold tube 18. The telescopic cylinder 11 is electrically connected to a controller via a five-position three-way solenoid valve.

[0045] When using the above solution, the sleeve box 3 moves downward to press the bottom 901 of the paperboard 9 to push it into the mold tube 18. Under the action of the first guide plate 17, the other parts of the paper box enter the mold tube 18 along the first guide plate 17. Under the encirclement of the sleeve box 3, the front tube plate 33, the rear tube plate 32, the upper left tube plate 34, and the upper right tube plate 35, the front box wall 902, the rear box wall 903, and the side box walls 905 at the left and right ends are folded upward to preliminarily form a rectangular box body. As the sleeve box 3 continues to be pressed downward, the side fold portion 906 and the side cover portion 907, when passing through the interval between the upper left tube plate 34 and the lower left tube plate 36, and the interval between the upper right tube plate 35 and the lower right tube plate 37, first retract inwardly under the action of the second guide plate 19, and then gradually press toward the outer side surface of the side box wall 905 under the action of the third guide plate 20, and the side fold portion 906 is bonded to the side box wall 905 under the action of the quick-drying hot melt adhesive, and forms a stable connection under the extrusion of the sleeve box 3 and the lower left tube plate 36 and the lower right tube plate 37, while the side cover portion 907 and the box top 904 are bent, thereby forming an unfinished body of the rectangular box.

[0046] The folding box mold also includes a mounting platform 23 arranged below the mold tube 18. The mounting platform 23 is fixedly mounted on the frame 1. A downward-penetrating material discharge port is provided on the upper end surface of the mounting platform 23. A receiving box 24 with an upper end opening and a rear end opening is also fixedly mounted on the upper end of the mounting platform 23. The receiving box 24 is arranged directly below the mold tube 18 for receiving the unfinished body of the rectangular box body. The bottom of the receiving box 24 is connected to the discharge port. A receiving plate 31 is hinged on the inner wall of the front end wall of the receiving box 24 through a torsion spring hinge. The receiving plate 31 is in a horizontal state when no force is applied. When the upper end of the receiving plate 31 is subjected to physical gravity, the rear end of the receiving plate 31 rotates downward. The second conveyor belt 4 is arranged next to the frame 1 and is used to convey the line reel 5 to slide from above into the receiving box 24.

[0047] It should be particularly noted that the second conveyor belt 4 is a roller conveyor belt with active rolling transportation and is set at an angle. After the wire reel 5 comes down from the production line, it is directly connected to the second conveyor belt 4 and slides into the receiving box 24 along the second conveyor belt 4 under the action of gravity and active transportation.

[0048] When using the above scheme, the sleeve pressing box 3 pushes the unfinished body of the rectangular box downward to move into the receiving box 24 until the box bottom 901 contacts the receiving plate 31, and then the telescopic cylinder 11 pulls the sleeve pressing box 3 up and away, and the wire drum 5 slides into the paper box from the second conveyor belt 4. Under the action of the gravity of the wire drum 5, the receiving plate 31 rotates downward, and the wire drum 5 and the paper box slide out from the rear end of the receiving box 24 along the inclined receiving plate 31.

[0049] Preferably, an impact plate 21 is further provided under the rear tube plate 32, and the top of the impact plate 21 is hinged to the bottom of the rear tube plate 32 through a torsion spring hinge. When the impact plate 21 is not subjected to external force, the front end surface of the impact plate 21 is in the same plane as the front end surface of the rear tube plate 32. When the impact plate 21 is impacted by external force, the bottom of the impact plate 21 rotates backward. An arc-shaped sixth guide plate 22 is also provided at the bottom of the impact plate 21, and the bottom of the sixth guide plate 22 bends backward and extends downward.

[0050] When the above solution is used, when the wire drum 5 slides into the paper box, the conveying speed of the second conveyor belt 4 can be increased to make the wire drum 5 fly out quickly, and the impact plate 21 can preferentially absorb part of the impact force of the wire drum 5 through the backward rotation of the torsion spring hinge, so that the wire drum 5 can fall into the paper box (abbreviation of the rectangular box body) in the receiving box 24 more reliably. At the same time, the sixth guide plate 22 at the bottom of the impact plate 21 can effectively pre-bend the box top 904.

[0051] An inclined blanking plate 25 arranged along the front-to-back direction is also provided below the mounting platform 23 , the rear end of the blanking plate 25 is lower than the front end of the blanking plate 25 , and the front end of the blanking plate 25 extends to the front end of the blanking port and is fixedly connected to the bottom of the mounting platform 23 .

[0052] The second glue coating mechanism is arranged beside the blanking plate 25 and is used for spraying the left and right side surfaces of the rectangular box body passing through the blanking plate 25 .

[0053] Specifically, the second glue coating mechanism includes a fourth bracket (shown in the figure but not marked) arranged beside the frame 1, and a second glue sprayer 26 and a second sensor 27 are fixedly arranged on the fourth bracket, and the second glue sprayer 26 and the second sensor 27 are both electrically connected to the controller. Preferably, the second glue sprayer 26 is a quick-drying hot melt glue sprayer, and the second sensor 27 is an infrared sensor.

[0054] When using the above solution, the incomplete rectangular box body containing the wire reel 5 slides downward and backward along with the receiving plate 31 and falls into the unloading plate 25. When passing through the second gluing mechanism, the second sensor 27 detects the paper box, and the second glue sprayer 26 sprays quick-drying hot melt glue on the side folding part 906.

[0055] The folding box mold also includes a fourth guide plate 2922 and a fifth guide plate 30 which are arranged above the blanking plate 25 and behind the second gluing mechanism. The fourth guide plate 2922 and the fifth guide plate 30 are respectively fixed on the frame 1. The fourth guide plate 2922 consists of two pieces and are respectively arranged at the left and right ends of the blanking plate 25. The fifth guide plate 30 is arranged above the two fourth guide plates 2922.

[0056] Specifically, the front end of the fourth guide plate 2922 bends and extends forward in a direction away from the blanking plate 25 .

[0057] Specifically, the front end of the fifth guide plate 30 is bent and extends upward in a direction away from the blanking plate 25 .

[0058] When the above solution is used, when the incomplete rectangular box body passes through the fourth guide plate 2922 and the fifth guide plate 30, the box top 904 is bent downward under the guidance of the fifth guide plate 30, and at the same time, the side cover portion 907 is bent inward under the guidance of the fourth guide plate 2922 to fit with the side fold portion 906, and is quickly bonded to the side fold portion 906 under the action of the quick-drying hot melt adhesive, thereby forming a complete rectangular box body. It should be noted that the front cover portion 908 has not been bonded at this time, but the entire wire drum 5 has been sealed and installed in the paper box, so the paperboard 9 is counted as a complete rectangular box body here. The remaining front cover portion 908 can be selected for subsequent manual folding and gluing, or folding and gluing by equipment, which are very easy to implement steps and are not included in the inventive structure that needs to be protected in the present disclosure.

[0059] The third conveyor belt 10 is arranged on the frame 1 and is used to receive the rectangular boxes discharged from the blanking plate 25 .

[0060] Preferably, a limiting plate 28 is further provided on the blanking plate 25 at the front end of the fourth guide plate 2922 . There are two limiting plates 28 which are parallel to each other. The limiting plates 28 are respectively fixed to the left and right ends of the upper end surface of the blanking plate 25 .

[0061] When the above solution is used, the limiting plate 28 is provided to more accurately guide the paper box to slide from the receiving box 24 into the fourth guide plate 2922 and the fifth guide plate 30 .

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
