Carton opening system

Abstract

The invention discloses a carton opening system. The carton opening system comprises an unfolded carton conveying mechanism (1), and box forming mechanism (2) for changing unfolded cartons as boxes; the unfolded carton conveying mechanism (1) comprises a frame (3), a base (4) and a linear driving mechanism; a driven rotating shaft (5) and a driving rotating shaft (6) are rotationally mounted at the left and right ends of the frame (3) in the frame (3); a servo motor (7) is fixedly mounted on the side surface of the frame (3); an output shaft of the servo motor (7) is connected with one end ofthe driving rotating shaft (6) by a coupling; two driving belt wheels (8) are mounted on the driving rotating shaft (6); and two driven belt wheels (9), corresponding to the driving belt wheels (8), are mounted on the driven rotating shaft (5). The carton opening system has the characteristics of no need of workers to take and unfold the cartons, high carton opening efficiency, relief of the laborintensity of workers, high box strength after opening, beautiful boxes after opening and reduction of the box opening cost.

Description

technical field [0001] The invention relates to the technical field of carton forming, in particular to a carton unpacking system. Background technique [0002] When packaging home appliances, the cartons used to package the products need to be unpacked and formed first. The cartons are flat before being unpacked, such as Figure 8 Shown is a structural schematic diagram of the carton in an unfolded state, wherein a bottom plate 31, a top cover 33 and four side plates 32, the four side plates 32 are respectively butted with the four sides of the bottom plate 31, and the top cover 33 is butted with any one of the side plates 32 To open the flat carton to form a square box, the specific operation steps are that the worker presses the bottom plate 31 with his hands, and then folds the four side plates around the joints with the bottom plate 31 to ensure that the sides The board 32 is in the state of being vertical to the bottom board 31, and then the adjacent side boards are bo...

[0002] When packaging home appliances, the cartons used to package the products need to be unpacked and formed first. The cartons are flat before being unpacked, such as Figure 8 Shown is a structural schematic diagram of the carton in an unfolded state, wherein a bottom plate 31, a top cover 33 and four side plates 32, the four side plates 32 are respectively butted with the four sides of the bottom plate 31, and the top cover 33 is butted with any one of the side plates 32 To open the flat carton to form a square box, the specific operation steps are that the worker presses the bottom plate 31 with his hands, and then folds the four side plates around the joints with the bottom plate 31 to ensure that the sides The board 32 is in the state of being vertical to the bottom board 31, and then the adjacent side boards are bonded together in the form of an adhesive tape or hot-melt glue is sprayed to the contact between the two adjacent side boards 32. In this way of operation, The carton in the unfolded state can be transformed into a square shape. However, it takes about 3 to 5 minutes to unpack the box manually, which has the disadvantage of low unpacking efficiency.

[0003] Most of the unpacking operations are carried out in the workshop, and usually operated by multiple workers at the same time, which not only takes up a lot of workshop space, but is not conducive to the passage of employees. Due to the large number of employees involved, the cost of unpacking is further increased, which is very uneconomical

In addition, manual unpacking also has the following defects: (1) when the worker uses a glue gun to spray glue on the contact between the two side panels, the glue may be sprayed onto the surface of the side panels due to careless operation, and the hot melt adhesive will After solidification, it is difficult to wipe off the surface of the side panel, which reduces the surface quality of the box after unpacking, and is difficult to meet the needs of customers

(2) When the worker uses the glue gun, the hot melt glue sprayed out hits the skin, causing the entire skin epidermis to be torn off when tearing, which is very unsafe

(3) Due to the lack of experience of the employees in using glue guns, the hot melt glue between the two side walls is not continuous, which will lead to the box strength not meeting the requirements

(4) The cartons in the unfolded state are stacked very high, and the workers have to gradually take the cartons from the top to unpack the cartons, but some workers are not high enough to take them, and the operation for the workers remains unchanged

However, this forming device has a complex structure and is difficult to manufacture. At the same time, there is no structure for automatically picking up cartons, and it also cannot solve the technical problem that workers cannot pick up the unfolded cartons because they are stacked very high.
