Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically a high-speed automatic cardboard box bundling machine. Background Technology

[0002] A carton bundling machine is a machine that uses strapping to wrap flattened and stacked cartons, and then uses heat to melt or tighten the ends of the strapping to complete the packaging, thereby ensuring that the cartons remain neatly stacked and do not fall apart during transportation and storage.

[0003] Currently, some cardboard box strapping machines exist on the market, which improve strapping efficiency to some extent. However, these machines still have some shortcomings during operation. For example, many existing cardboard box strapping machines require multiple adjustments to the orientation of the cardboard boxes when strapping stacked boxes to ensure that the strapping tape is evenly wrapped around the outside of the boxes. This step not only increases the complexity of the operation but also reduces the overall strapping efficiency. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 and Figure 2 A high-speed automatic cardboard box strapping machine may include a base 10, a ball screw mechanism 20, a packing tray 30, a linear drive source 40, a pressure plate 50, and a strapping mechanism 60. An opening 11 is formed in the base 10, and the ball screw mechanism 20 is installed inside the base 10. The packing tray 30 is detachably mounted on a lead screw seat in the ball screw mechanism 20, and the ball screw mechanism 20 drives the packing tray 30 to translate through the opening 11. The ball screw mechanism 20 is prior art, which uses a motor-driven screw to drive the lead screw seat, which can translate along the screw axis; details will not be elaborated here. The packing tray 30 may be made of plastic sheet using injection molding, and a groove is pre-drilled at the bottom of the packing tray 30 so that it can snap onto the lead screw seat and move with the lead screw seat. A linear drive source 40 is mounted on top of the base 10, and its output end is connected to a pressure plate 50, allowing the pressure plate 50 to be driven and movably positioned above the packing pallet 30. The pressure plate 50 can be adjusted in height to limit the stacked cartons, preventing them from scattering when the packing pallet 30 moves the stacked cartons horizontally. The width of the pressure plate 50 matches the width of the packing pallet 30, and a rubber pad is adhesively fixed to the lower surface of the pressure plate 50 to reduce wear on the cartons. The pressure plate 50 is located inside the base 10 and near the opening 11, allowing it to limit the cartons as the packing pallet 30 moves them through the opening 11. A binding mechanism 60 is mounted on the outside of the base 10 near the opening 11, and is used to unwind and wrap the binding tape around the packing pallet 30 and the outside of the stacked cartons. The high-speed automatic cardboard strapping machine may also include pneumatic scissors, allowing it to cut the strapping after wrapping, and then manually tighten both ends of the strapping. Alternatively, the high-speed automatic cardboard strapping machine may also include a heating mechanism already available in the prior art, allowing it to melt the strapping after wrapping.

[0021] See Figure 3The binding mechanism 60 includes a rotating ring 61, a shaft 62, a drive wheel 63, several transmission wheels 64, a transmission belt 65, several auxiliary wheels 66, and a drive motor. The rotating ring 61 is coaxially distributed with the opening 11, and the inner diameter of the rotating ring 61 is adapted to the diameter of the opening 11. Both the inner diameter of the rotating ring 61 and the diameter of the opening 11 are larger than the width of the packing pallet 30, so that the packing pallet 30 can hold a certain number of cartons that pass through the opening 11 and the rotating ring 61. The shaft 62 is fixedly connected to the side of the rotating ring 61 facing away from the base 10, and the shaft 62 is used to hold the binding tape roll. The end of the shaft 62 facing away from the rotating ring 61 has an external thread, and the end of the shaft 62 is fitted with a threaded ring that is threadedly connected to it. The binding tape roll is placed between the threaded ring and the rotating ring 61, so that the threaded ring can be used to prevent the binding tape roll from falling off the shaft 62. A drive motor is mounted and fixed on the base 10, and its output end is connected to the drive wheel 63, enabling it to rotate the drive wheel 63. Several transmission wheels 64 are rotatably connected to the base 10 via a rotating shaft. A transmission belt 65 is fitted over the drive wheel 63 and the several transmission wheels 64 and is connected to them for transmission. The side of the transmission belt 65 closest to the rotating ring 61 contacts the outer wall of the rotating ring 61. Several auxiliary wheels 66 are spaced apart and tangentially distributed on the outside of the rotating ring 61, and each auxiliary wheel 66 is rotatably connected to the base 10 via a rotating shaft. Thus, the rotating ring 61 can rotate between the transmission belt 65 and the multiple auxiliary wheels 66 using the transmission of the transmission belt 65 and the rotation and support of the auxiliary wheels 66. During rotation, the rotating ring 61 can simultaneously drive the binding straps to wrap around the packing pallet 30 and the stacked cartons above it. The ball screw mechanism 20 can drive the packing pallet 30 to support multiple stacked and flattened cartons through the opening 11, and the binding mechanism 60 can drive the binding tape to unwind and wrap around the outside of the moving cartons, so that the cartons can be bound to the packing pallet 30 at once when packing, avoiding the extra time spent by turning the stacked cartons multiple times when binding the cartons, and improving the speed of packing the cartons.

[0022] In this embodiment, the linear drive source 40 can be one of the hydraulic push rod, pneumatic push rod or electric push rod that are already available in the prior art.

[0023] In this embodiment, the binding tape roll can be made of polypropylene plastic into a strip roll.

[0024] The system of the present invention may further include a control system for controlling the automatic operation of the aforementioned drive sources to perform automatic operations of carton transport and bundling. It should be understood that the control system is not particularly limited and can be implemented using existing control technologies, which will not be elaborated upon here.

[0025] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model 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 this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
