Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, specifically to a case opener. Background Technology

[0002] In modern packaging production, carton erectors are an indispensable piece of equipment. They are mainly used to automatically open and shape folded cartons so that products can be packed into boxes later.

[0003] However, existing vertical carton erecting machines have several drawbacks: First, the carton storage compartment is located on the side, resulting in a large footprint and severely impacting space utilization in production environments with limited workshop width. Second, the carton retrieval method uses cylinder drive, which, limited by cylinder diameter, results in a slow carton retrieval and opening speed, failing to meet the ever-increasing demands for production efficiency. Third, due to its structure, the opening range is limited, with a minimum opening width and height of only 150mm, making it unsuitable for opening smaller cartons. Fourth, changing carton sizes requires adjusting numerous mechanisms, leading to cumbersome operations, increased labor costs, and reduced production efficiency.

[0004] Therefore, there is an urgent need to design a new type of box-opening machine to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] Reference Figure 1 As shown in this embodiment, a carton opener includes a main unit 1, which is equipped with a carton storage trough 2, a carton picking mechanism 8, a carton clamping and conveying mechanism 11, and an electrical control device 5. The carton storage trough 2 is installed at the feeding end of the main unit 1 and is on the same straight line as the main unit 1 along the same path as the carton. This layout design greatly reduces the floor space occupied by the equipment, and is especially suitable for situations where the workshop width is limited. The carton storage trough 2 is equipped with a carton pressing plate mechanism 3 and a carton width adjustment mechanism 16.

[0023] The main equipment 1 is also equipped with a servo drive mechanism 6 for controlling the action of the box-picking mechanism 8; the box-picking mechanism 8 is equipped with a vacuum suction cup for adsorbing cartons. Compared with traditional cylinder drive, servo drive can achieve stepless speed regulation, thereby increasing the box-opening speed by 30% compared with previous equipment, effectively improving production efficiency.

[0024] The main equipment 1 is also equipped with a carton forming device, including: a carton forming mechanism 7 that guides and assists in the initial forming of the carton; a front folding forming device 18 that completes the front folding action of the carton; a rear folding mechanism 9 that completes the rear folding action of the carton; and a left and right folding mechanism 10 that completes the left and right folding actions of the carton. The carton is formed through the coordinated work of each component. At the same time, through the cooperation of the storage box pressing plate mechanism 3, the storage box height adjustment mechanism 4, the pressing box height adjustment mechanism 14, the storage box width adjustment mechanism 16, and the carton clamping and conveying mechanism 11, the carton forming and conveying adjustments can be completed simultaneously when the carton size is adjusted. Compared with previous equipment, the convenience and efficiency of carton adjustment are greatly improved.

[0025] A protective cover 15 is fixed above the main equipment 1, and a pressure box height adjustment mechanism 14 is installed in the middle of the protective cover 15; an upper pressure box plate mechanism 13 is provided below the pressure box height adjustment mechanism 14.

[0026] The carton clamping and conveying mechanism 11 is equipped with a conveyor width adjustment mechanism 12; a carton tape dispenser 17 is provided between the two clamping arms of the carton clamping and conveying mechanism 11. By using the carton tape dispenser 17, the minimum opening width of the carton opener can reach 130mm, and the minimum opening height can reach 90mm, significantly expanding the opening range and adapting to the opening needs of more carton sizes and specifications.

[0027] The working principle of the box opener described in this utility model is briefly described as follows:

[0028] During operation, the folded cardboard box is first placed upright on the storage trough 2 by a worker. Then, the storage box pressing mechanism 3 is activated to press the cardboard box. The operator operates the storage box height adjustment mechanism 4 to align the bottom crease line of the cardboard box with the top surface of the cardboard box tape dispenser 17 at the cardboard box outlet. Then, according to the height of the cardboard box, the operator operates the pressing height adjustment mechanism 14 to align the pressing plate of the upper pressing plate mechanism 13 with the upper edge of the cardboard box fold. Finally, the operator operates the lead screw of the storage box width adjustment mechanism 16 to align the center line of the cardboard box width with the center line of the sealing tape of the cardboard box tape dispenser 17, and then limits the cardboard box into the trough.

[0029] After completing the above preparations, the servo drive mechanism 6 starts to operate, driving the box-picking mechanism 8 to run. Since the box-picking mechanism 8 is equipped with a vacuum suction cup, it can smoothly pull the carton out of the storage tank 2. During the pulling process, the carton forming mechanism 7 plays a guiding role, assisting the carton to achieve initial forming. When the carton continues to move to the front folding forming device 18, the front fold of the carton is completed. Immediately afterwards, the folding cylinder in the rear folding mechanism 9 is activated to complete the rear fold of the carton. Subsequently, the carton continues to move forward, and under the guidance of the round steel of the left and right folding mechanisms 10, the left and right folding operations of the carton are completed, and the carton is now fully formed.

[0030] The formed carton is fed forward to the carton clamping and conveying mechanism 11. At this time, the vacuum suction cup on the carton picking mechanism 8 releases the carton, and the rotary cylinder in the carton picking mechanism 8 rotates 90° away from the carton. The servo drive mechanism 6 returns to the storage tank 2 and repeats the carton picking action. Under the conveying of the carton clamping and conveying mechanism 11, the carton passes through the carton tape dispenser 17 to complete the tape sealing operation on the bottom of the carton, and is finally conveyed to the carton outlet to enter the next station; thus, the entire carton opening process completes one cycle.

[0031] Through the detailed structural design and rigorous workflow described above, this utility model of the box opener effectively solves many problems existing in the current vertical box opener, and realizes efficient, convenient and multifunctional box opening operations.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
