Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a bundling device for cartons. Background Art

[0002] Cartons are widely used in the packaging and transportation industry because of their durability, ease of processing, low cost, recyclability, and environmental friendliness. During the carton processing process, the cartons need to be stacked in an orderly manner to a certain height, and then stacked and bundled for transportation.

[0003] The Chinese patent with the publication number CN117533571B discloses an automatic packaging device for packaging cartons. When in use, four L-shaped strips are arranged at the corners of the carton stack before the bundling operation is performed. The corners of the carton stack are protected by the L-shaped strips, which effectively avoids the problem of the top and bottom cartons being crushed by the straps. The upper L-shaped strip is reinforced and supported by the cooperation of the fixed plate 2 and the groove strip, which effectively avoids the problem of interfering with the manual placement of the carton stack due to the downward bending of the end of the L-shaped strip. The groove block 1 and the groove block 2 are also used to block and limit the straps to prevent the straps from falling off the L-shaped strips, which is conducive to improving the bundling stability.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the strapping machine can only strap the stacked cartons in the horizontal direction. As the stacking height of the cartons increases, the strapped cartons are prone to loosening and falling off during subsequent transportation, thereby reducing the strapping quality.

DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figures 1 to 4 As shown, the utility model proposes a bundling device for cartons, comprising a first bundling machine 1 and an adjustment mechanism; the output end of the first bundling machine 1 is detachably connected to a workbench 3, and the output end of the workbench 3 is detachably connected to a second bundling machine 101, and the first bundling machine 1 and the second bundling machine 101 have the same structure; the adjustment mechanism is arranged on the workbench 3, and the adjustment mechanism is used to adjust the angle of the cartons that have been bundled horizontally by the first bundling machine 1 and then transfer them to the second bundling machine 101 for longitudinal bundling.

[0022] Furthermore, the adjustment mechanism includes a rotating table 4 and a conveying mechanism; the rotating table 4 is driven to rotate and connect the workbench 3 by a driving mechanism arranged inside the workbench 3, and a circular opening matched with the rotating table 4 is opened at the top of the workbench 3, and the top surface of the rotating table 4 and the top surface of the workbench 3 are located on the same horizontal plane; the conveying mechanism is arranged inside the rotating table 4, and the conveying mechanism is composed of a first conveying component and a second conveying component. A plurality of groups of longitudinal openings 401 and transverse openings 402 are opened at the top of the rotating table 4, the longitudinal opening 401 is matched with the second conveying component, and the transverse opening 402 is matched with the first conveying component, and the conveying mechanism is used to convey the cartons that have been transversely strapped by the first strapping machine 1 to the second strapping machine 101.

[0023] Furthermore, the driving mechanism includes a driving gear 302 and a driven gear ring 303; the driving gear 302 is driven to rotate by a first motor installed inside the workbench 3; the driven gear ring 303 is arranged on the outer circumference of the rotating table 4, and the driving gear 302 is meshed and connected to the driven gear ring 303.

[0024] The first motor drives the driving gear 302 to rotate, which can drive the driven gear ring 303 to rotate, and then drive the rotating table 4 to rotate along the workbench 3 to a suitable angle, thereby driving the first transmission mechanism and the second transmission mechanism inside the rotating table 4 to switch working states.

[0025] Furthermore, the first conveying component includes a first mounting seat 6; the first mounting seat 6 is connected to the inner bottom end of the rotating table 4 through a first electric push rod, two groups of channels 601 are symmetrically opened on the first mounting seat 6, and the channels 601 are adapted to the second conveying component, and multiple groups of transverse conveying rollers 7 are transversely arranged on the first mounting seat 6, and the multiple groups of transverse conveying rollers 7 are driven to rotate by the second motor, and the transverse conveying rollers 7 are adapted to the transverse opening 402.

[0026] Furthermore, the second conveying assembly includes a second mounting seat 8 and a longitudinal conveying roller 9; the second mounting seat 8 is connected to the inner bottom end of the rotating table 4 through a second electric push rod, and the second mounting seat 8 is arranged through the channel 601; multiple groups of longitudinal conveying rollers 9 are arranged, and multiple groups of longitudinal conveying rollers 9 are longitudinally arranged on the second mounting seat 8, and a transmission assembly 901 is connected between the multiple groups of second mounting seats 8, and the transmission assembly 901 is driven to rotate by a third motor, and the transmission assembly 901 is set as a chain transmission assembly.

[0027] In this embodiment, after the stacked cartons are transversely strapped on the first strapping machine 1, they are conveyed toward the workbench 3. The first mounting seat 6 is driven upward by the first electric push rod until the upper ends of the outer circumferences of the multiple groups of transverse conveying rollers 7 are exposed to the outside of the transverse opening 402. The transverse conveying rollers 7 are driven to rotate by the second motor to convey the cartons to a suitable position on the workbench 3. Then the first mounting seat 6 is restored to its original position, and the second mounting seat 8 is driven upward by the second electric push rod until the upper ends of the outer circumferences of the longitudinal conveying rollers 9 are exposed to the outside of the longitudinal opening 401. At the same time, the rotating table 4 is driven to rotate 90 degrees by the driving mechanism. At this time, the angle of the carton relative to the workbench 3 is adjusted.

The cartons are conveyed toward the second strapping machine 101 by the multiple groups of longitudinal conveying rollers 9, and are further strapped by the second strapping machine 101. Since the direction of the cartons is adjusted on the workbench 3, the strapping of the cartons by the second strapping machine 101 is equivalent to longitudinal strapping, which makes the stacked cartons more firmly strapped and avoids looseness during subsequent transportation.

[0030] Furthermore, a slot 301 is provided on the side wall of the workbench 3, and an insertion rod is installed on the end of the first strapping machine 1 or the second strapping machine 101 connected to the workbench 3. The insertion rod is adapted to the slot 301 and is used to quickly align the workbench 3 with the first strapping machine 1 or the second strapping machine 101 for easy connection.

[0031] In this embodiment, the limit plate 201 is clamped between two adjacent groups of screw rods 2, and then the nut 202 is threadedly connected to the screw rod 2 until the nut 202 presses the limit plate 201 against the side wall of the workbench 3, so that the workbench 3 can be connected to the first strapping machine 1 or the second strapping machine 101, thereby improving the overall stability and facilitating disassembly and assembly.
