Description

Technical Field

[0001] This invention relates to the field of cardboard box bundling technology, specifically to a semi-automatic bundling device for cardboard box production. Background Technology

[0002] Strapping machines, also known as packing machines, use strapping tape to wrap around products or packaging components, tighten it, and heat-melt the two ends with a heating head to ensure that the plastic tape adheres tightly to the surface of the package. This prevents the package from falling apart during transportation and storage due to loose strapping, while also ensuring that the strapping is neat, aesthetically pleasing, and efficient.

[0003] While existing strapping machines can be adjusted according to the size of the carton, they cannot make fine adjustments because the rigidity of cartons of the same size may vary. For cartons of the same model, the outer wall of the softer carton is easily damaged when moving after being strapped together. If the straps are too tight, they will put too much pressure on the carton, causing the shape of the carton to change. This will not only affect the appearance of the carton, but may also reduce the internal space of the carton, affecting its ability to hold and protect the items. Therefore, we propose a semi-automatic strapping device for carton production. Summary of the Invention

[0004] The present invention provides the following technical solution: a semi-automatic strapping device for carton production, comprising a conveyor table and a support base. Conveyor rollers are fixedly installed at both ends of the sidewalls of the conveyor table. A bottom conveyor belt is fixedly installed on the inner wall of the conveyor table. Two sidewall conveyor belts are fixedly installed on the top of the conveyor table near the bottom conveyor belt. The two sidewall conveyor belts are symmetrically distributed on the top of the conveyor table. Two elastic pressure plates are fixedly installed at the ends of the sidewalls of the two sidewall conveyor belts. A toothed rack is horizontally installed at the top of each of the two elastic pressure plates. A strapping table is fixedly installed on the sidewall of the conveyor table, and a fixing post that meshes with the toothed rack is provided on the sidewall of the strapping table near the toothed rack. A connecting rod is fixedly provided at the bottom end of the two elastic pressure plates. A rotating component is fixedly provided on the top of the conveyor table near the connecting rod, and the position of the rotating component corresponds to the position of the connecting rod. A second gear is provided on the side wall of the rotating component and meshes with it. A moving component is fixedly provided on the top of the conveyor table. The moving component includes a fixed seat provided on the top of the conveyor table. The fixed seat is connected to the fixed plate through a moving block slidably provided on the top. A limit groove A is opened on the top of the fixed seat. The side wall of the limit groove A is slidably connected to the fixed seat through three pads.

[0005] Preferably, the sidewall of the second gear has five extended tooth blocks on the side near the pad, and the sidewall of the five extended tooth blocks is rotatably connected to the second gear by a first rotating shaft.

[0006] Preferably, the sidewalls of the two elastic pressure plates are elastically connected to the sidewall conveyor belt by means of springs, and the surface of the elastic pressure plates is an arc panel.

[0007] Preferably, the side wall of the strapping table is provided with cable tie fixing grooves at both ends, and the top of the conveyor table is provided with a strapping opening on the side near the cable tie fixing groove, and the position of the cable tie fixing groove corresponds to the position of the strapping opening.

[0008] Preferably, the racks at the top of the two elastic pressure plates are arranged adjacent to each other, and the racks are engaged with the fixing posts.

[0009] Preferably, the rotating assembly includes a third gear located at the top of the conveyor, and a first gear that rotates synchronously is fixedly mounted on the top of the third gear, and the rotational speed of the third gear is greater than that of the first gear.

[0010] Preferably, the movable component further includes an L-shaped fixing block fixedly disposed on the side wall of the fixed seat. The side wall of the fixed seat has a limiting groove B on the side near the movable block. The inner wall of the movable block is rotatably connected to a rotating plate via a second rotating shaft. The position of the rotating plate corresponds to the position of the L-shaped fixing block. The side wall of the rotating plate is provided with one end of a spring telescopic rod, and the other end of the spring telescopic rod is connected to the movable block.

[0011] Preferably, the side wall of the fixed base has a sliding groove at one end near the movable block, and the bottom of the fixed plate slides in the sliding groove by means of a movable block fixedly installed therein.

[0012] Preferably, the bottom of the three pads is provided with a slider, and the three pads are magnetically connected to the slider. The side walls of the three pads are fixed with corresponding magnetic blocks.

[0013] Preferably, the positions of the five extended tooth blocks correspond to the positions of the three pads, and the tops of the five extended tooth blocks are alternately arranged with the three pads.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This semi-automatic strapping equipment for cardboard box production cannot make fine adjustments during strapping because cardboard boxes of the same size may have inconsistent stiffness. For the same model of cardboard box, the softer outer wall is more prone to damage during movement after strapping. When the cardboard box moves to the strapping point, the fixing plate is positioned against the side wall of the cardboard box. When the strapping strap in the fixing slot falls, it straps the fixing plate and pad that have moved to the side wall of the cardboard box along with the box. Slight adjustments to the tightness of the strapping are necessary. Softer cardboard boxes have relatively weaker compressive strength; overly tight straps will apply excessive pressure to the box. This is to prevent changes in the shape of the cardboard box and reduce the risk of dents, twists, etc., which not only affect the appearance of the cardboard box but may also reduce the internal space, affecting its ability to hold and protect items. This semi-automatic strapping equipment for carton production involves conveying cartons to the bottom conveyor belt via a conveyor roller. Above the bottom conveyor belt are two corresponding side wall conveyor belts. The two side wall conveyor belts effectively improve the stability of the cartons during the transmission process and reduce the possibility of the cartons tilting during movement. This prevents inefficiency and insecure strapping caused by positional deviation when the cartons are subsequently conveyed to the strapping opening for strapping.

[0015] 3. The semi-automatic strapping equipment for carton production also minimizes the bending of the elastic pressure plate when a softer carton passes through it. The toothed rack at the top of the elastic pressure plate effectively controls the uniformity of bending at both ends, ensuring the accuracy of the elastic pressure plate during bending and reducing uneven bending caused by external interference.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8 A semi-automatic strapping device for carton production includes a conveyor table 1 and a support base 23. Conveyor rollers 3 are fixed at both ends of the side wall of the conveyor table 1. A bottom conveyor belt 2 is fixed at the inner wall of the conveyor table 1. Two side wall conveyor belts 4 are fixed at the top of the conveyor table 1 near the bottom conveyor belt 2. The two side wall conveyor belts 4 are symmetrically distributed at the top of the conveyor table 1. Two elastic pressure plates 5 are fixed at the end of the side wall of the two side wall conveyor belts 4. A toothed rack 6 is horizontally arranged at the top of the two elastic pressure plates 5. A strapping table 8 is fixed at the side wall of the conveyor table 1. A fixing post 7 that meshes with the toothed rack 6 is provided on the side wall of the strapping table 8 near the toothed rack 6. Two elastic pressure plates 5 are fixedly provided with connecting rods 16 at their bottom ends. A rotating assembly is fixedly provided on the top of the conveyor platform 1 on the side near the connecting rods 16, and the position of the rotating assembly corresponds to the position of the connecting rods 16. A second gear 10 is provided on the side wall of the rotating assembly and meshes with it. A moving assembly is fixedly provided on the top of the conveyor platform 1. The moving assembly includes a fixed seat 12 provided on the top of the conveyor platform 1. The fixed seat 12 is connected to the fixed plate 24 through a moving block 26 slidably provided on the top. A limit groove A is provided on the top of the fixed seat 12. The side wall of the limit groove A is slidably connected to the fixed seat 12 through three pads 11.

[0020] It should be noted that when the cartons to be bundled are conveyed to the bottom conveyor belt 2 via the conveyor roller 3, two corresponding side wall conveyor belts 4 are provided above the bottom conveyor belt 2. The setting of the two side wall conveyor belts 4 not only improves the stability of the cartons during the transmission process and reduces the skewing phenomenon of the cartons during movement, but also effectively prevents the pad 11 from not fitting against the side wall of the cartons when they are bundled at the bundling opening 22. The cooperation between the two side wall conveyor belts 4 and the pad 11 avoids the phenomenon of low bundling efficiency and weak bundling caused by the inconsistent hardness of cartons of the same size. At the same time, the setting of the elastic pressure plate 5 effectively detects the softness and hardness of the cartons conveyed in the two side wall conveyor belts 4. By adjusting the bending angle of the elastic pressure plate 5, the number of pads 11 is adjusted to ensure that the softness and hardness of the cartons to be bundled matches the required number of pads 11, effectively improving the bundling efficiency and firmness.

[0021] In an optional embodiment: the sidewall of the second gear 10 is provided with five extended tooth blocks 14 on the side near the pad plate 11, and the sidewall of the five extended tooth blocks 14 is rotatably connected to the second gear 10 by a first rotating shaft 13.

[0022] It should be noted that the first rotating shaft 13 provided on the side wall of the extended tooth block 14 rotates to the vicinity of the fixed plate 24 after pushing the corresponding pad 11. The first rotating shaft 13 continues to move forward and bends after touching the fixed plate 24 to avoid collision with the fixed plate 24, thereby improving the accuracy of the equipment.

[0023] In an optional embodiment: the sidewalls of the two elastic pressure plates 5 are elastically connected to the sidewall conveyor belt 4 by means of springs, and the surface of the elastic pressure plate 5 is an arc panel.

[0024] It should be noted that the surface of the elastic pressure plate 5 is a curved panel, which effectively reduces the wear caused by the carton being squeezed by the elastic pressure plate 5.

[0025] In an optional embodiment: both ends of the side wall of the strapping table 8 are provided with cable tie fixing grooves 21, and the top of the conveyor table 1 is provided with a strapping opening 22 on the side near the cable tie fixing groove 21, and the position of the cable tie fixing groove 21 corresponds to the position of the strapping opening 22.

[0026] It should be noted that when the carton moves to the strapping opening 22, the cable ties fixed on the corresponding fixing slot 21 are ensured to accurately strap the carton, effectively improving the strapping efficiency of the equipment.

[0027] In an optional embodiment: the racks 6 at the top of the two elastic pressure plates 5 are arranged adjacent to each other, and the racks 6 are engaged with the fixing posts 7.

[0028] It should be noted that when a relatively soft cardboard box passes over the elastic pressure plate 5, the degree to which the elastic pressure plate 5 bends is small. The toothed rack 6 set at the upper end of the elastic pressure plate 5 effectively controls the uniformity of the bending degree of the elastic pressure plates 5 at both ends, reducing the uneven bending degree on both sides caused by external interference, and effectively ensuring the accuracy of the elastic pressure plate 5 when bending.

[0029] In an optional embodiment: the rotating assembly includes a third gear 15 located on top of the conveyor 1, the top of the third gear 15 is fixedly provided with a synchronously rotating first gear 9, and the rotational speed of the third gear 15 is greater than the rotational speed of the first gear 9.

[0030] It should be noted that the third gear 15 and the top first gear 9 rotate synchronously. However, since the diameter of the first gear 9 is larger than that of the third gear 15, the rotational speed of the third gear 15 is much greater than that of the first gear 9. This ensures that the rotation angle of the first gear 9 is smaller, thereby increasing the accuracy of the extension tooth block 14 driving the push 11.

[0031] In an optional embodiment, the movable component further includes an L-shaped fixing block 25 fixedly disposed on the side wall of the fixing seat 12. The side wall of the fixing seat 12 has a limiting groove B on the side near the movable block 26. The inner wall of the movable block 26 is rotatably connected to the rotating plate 18 by a second rotating shaft 19, and the position of the rotating plate 18 corresponds to the position of the L-shaped fixing block 25. The side wall of the rotating plate 18 is provided with one end of a spring telescopic rod 17, and the other end of the spring telescopic rod 17 is connected to the movable block 26.

[0032] It should be noted that the carton pushes the rotating plate 18 forward. When the rotating plate 18 moves to the front end of the L-shaped fixing block 25, since the position of the L-shaped fixing block 25 corresponds to the position of the rotating plate 18, the L-shaped fixing block 25 pushes the rotating plate 18 to rotate into the inner cavity of the moving block 26, and the carton can continue to be transported forward.

[0033] In an optional embodiment: the side wall of the fixed base 12 is provided with a groove 20 at one end near the movable block 26, and the bottom of the fixed plate 24 slides in the groove 20 by means of the movable block 26 fixedly installed.

[0034] In an optional embodiment: the bottom of the three pads 11 is provided with a slider, and the three pads 11 are magnetically connected to the slider, and the side walls of the three pads 11 are fixedly provided with corresponding magnetic blocks.

[0035] It should be noted that the side wall of the pad 11 is provided with a magnetic suction plate. The magnetic suction force of the magnetic suction plate is greater than the magnetic suction force between the bottom of the pad 11 and the sliding block. When the pad 11 is pushed close to the fixed plate 24, the fixed plate 24 attracts it, so that the pad 11 is separated from the slider.

[0036] In an optional embodiment: the positions of the five extended tooth blocks 14 correspond to the positions of the three pads 11, and the tops of the five extended tooth blocks 14 are alternately arranged with the three pads 11.

[0037] It should be noted that the softer the carton body to be bundled, the greater the counterclockwise rotation angle of the extension tooth block 14. Since the front end of the extension tooth block 14 is alternately set with the pad plate 11, the extension tooth block 14 pushes the pad plate 11 closer to the fixed plate 24 when it moves.

[0038] Working principle: When the carton to be bundled is conveyed to the bottom conveyor belt 2 by the conveyor roller 3, two corresponding side wall conveyor belts 4 are set above the bottom conveyor belt 2. The setting of the two side wall conveyor belts 4 effectively improves the stability of the carton during the transmission process and effectively reduces the phenomenon of the carton tilting during the movement. When the carton is subsequently conveyed to the bundling opening 22 for bundling, it is easy to cause inefficiency and weak bundling due to positional deviation. When the carton is conveyed to the side close to the elastic pressure plate 5, in the existing bundling technology, the cable tie can be adjusted according to the size of the carton during bundling. However, since the hardness of the carton of the same size may not be uniform, it is impossible to make fine adjustments during bundling. For the same model of carton, the outer wall of the carton with softer hardness is easily damaged when moving after the cable tie is used for bundling. When a relatively soft cardboard box passes over the elastic pressure plate 5, the degree to which the elastic pressure plate 5 bends is small. The rack 6 at the upper end of the elastic pressure plate 5 effectively controls the uniformity of the bending degree of the elastic pressure plates 5 at both ends, effectively ensuring the accuracy of the elastic pressure plate 5 when bending and reducing the uneven bending degree on both sides caused by external interference. At this time, the connecting rod 16 at the bottom of the elastic pressure plate 5 drives the third gear 15 to rotate. The third gear 15 rotates synchronously with the first gear 9 at the top. However, since the diameter of the first gear 9 is larger than that of the third gear 15, the rotational speed of the third gear 15 is much greater than that of the first gear 9. The rotation speed of gear 9 is such that when the first gear 9 drives the second gear 10 to rotate, the rotation distance of the extended tooth block 14 set at the front end of the second gear 10 matches the degree of bending of the elastic pressure plate 5. The softer the carton body to be bundled, the greater the counterclockwise rotation angle of the extended tooth block 14. Since the front end of the extended tooth block 14 is alternately set with the pad 11, the more pads 11 are pushed towards the fixed plate 24 when the extended tooth block 14 moves. The bottom of the pad 11 and the slider are magnetically attached, and the number of pads 11 can be gradually increased or decreased according to the actual situation. The first rotating shaft 13, which is provided on the side wall of the extended tooth block 14, rotates to the vicinity of the fixed plate 24 after pushing the corresponding pad 11. The first rotating shaft 13 continues to move forward and bends after touching the fixed plate 24 to avoid collision with the fixed plate 24. Since the side wall of the pad 11 is provided with a magnetic suction plate, the magnetic attraction force of the magnetic suction plate is greater than the magnetic attraction force between the bottom of the pad 11 and the sliding block. When the pad 11 is pushed close to the fixed plate 24, the fixed plate 24 attracts it, so that the pad 11 is separated from the slider. When the carton is transported to the vicinity of the moving block 26, since the inner wall of the moving block 26 is rotatably connected to the rotating plate 18, the carton pushes the rotating plate 18 forward. When the rotating plate 18 moves to the front end of the L-shaped fixed block 25, since the position of the L-shaped fixed block 25 corresponds to the position of the rotating plate 18, the L-shaped fixed block 25 pushes the rotating plate 18 to rotate into the inner cavity of the first rotating shaft 13, so that the carton can continue to be transported forward. The fixed plate 24, which moves to the top of the fixed base 12, corresponds to the position of the binding opening 22. When the carton moves to the binding opening 22, the fixed plate 24 is in contact with the side wall of the carton. When the cable tie placed at the cable tie fixing groove 21 falls, it will bind the fixed plate 24, the pad 11, and the carton together. The tightness of the binding should be adjusted to a small extent to reduce the pressure on the relatively soft carton. If the cable tie is too tight, it will put too much pressure on the carton, causing the shape of the carton to change, such as dents or twists. This will not only affect the appearance of the carton, but may also reduce the internal space of the carton, affecting its ability to hold and protect the items.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
