[0020] Please see Figures 1 to 3 A carton opening mechanism for a carton opener includes a mounting base 10, a guide rack 20 mounted on one side of the mounting base 10 for storing cartons to be opened, a first drive unit 30 connected to the guide rack 20 for driving the guide rack 20 to move vertically, a baffle plate 40 mounted above the outlet of the guide rack 20 for blocking the top of the carton, a second drive unit 50 connected to the baffle plate 40 for driving the baffle plate 40 to move vertically, and a suction unit 50 mounted on the mounting base 10 for picking up cartons from the guide rack 20. The system includes a suction unit 60, a third drive unit 70 connected to the suction unit 60 for driving the suction unit 60 to move toward the outlet of the guide rack 20, a mounting base 10 located on the outlet side of the guide rack 20 for abutting against the side of the carton when the carton moves from the guide rack 20 into the mounting base 10 to complete the carton opening process, and a fourth drive unit 90 connected to the arc guide plate 80 for driving the arc guide plate 80 to move on the opening side of the guide rack 20.

[0021] Specifically, in this embodiment, during operation, the carton to be opened is placed on the guide frame 20. At this time, the upper part of the carton is blocked by the baffle plate 40 to prevent it from slipping out of the guide frame 20. Then, the third drive unit 70 drives the suction unit to move towards the carton and moves the carton from the end of the guide frame 20 into the mounting base 10. During the movement of the carton, the arc-shaped guide plate 80 is set to complete the subsequent opening process. Furthermore, when the size of the carton changes, the second drive unit 50 drives the baffle plate 40 to move vertically as needed, and the first drive unit 30 drives the guide frame 20 to move vertically as needed, so that the baffle plate 40 can perform its blocking function. In addition, the fourth drive unit 90 drives the arc-shaped guide plate 80 to move as needed on the outlet side of the guide frame 20, so that it can meet the carton when it moves into the mounting base 10 according to the changed carton size and complete the opening process.

[0022] The case opening mechanism of the case opening machine involved in this utility model, through the first drive unit 30, the second drive unit 50 and the fourth drive unit 90, can adjust the position of the guide frame 20 and the arc guide plate 80 as needed according to the size of the carton to be opened, thereby effectively adapting to various carton sizes to be opened and improving the practicality of the case opening machine.

[0023] In one specific embodiment, the first drive unit 30 includes two first lifting platforms 301 mounted on the guide frame 20, a first slider vertically slidably mounted within the first lifting platform 301 and connected to the guide frame 20, a first transmission belt connected to the first slider for driving the first slider to move vertically up and down within the first lifting platform 301 during rotation, and a first motor 302 connected to the first transmission belt for driving the first transmission belt to rotate. Specifically, the first slider is vertically mounted within the first lifting platform 301 and connected to the first slider. During operation, the first motor 302 drives the first transmission belt to rotate, thereby causing the first slider to move vertically, thus driving the guide frame to move vertically up and down as needed.

[0024] In one specific embodiment, the second drive unit 50 includes a second lifting platform 501 mounted on one side of the baffle plate 40, a second slider 502 slidably mounted within the second lifting platform 501 and connected to the baffle plate 40, a second transmission belt 504 vertically mounted within the second lifting platform 501 and connected to the second slider 502 for vertically raising and lowering the second slider 502 during rotation, and a second motor 503 connected to the second transmission belt 504 for driving the second transmission belt 504 to rotate. Specifically, during operation, the second motor 503 drives the second transmission belt 504 to rotate, thereby causing the second slider 502 to vertically raise and lower as needed, thus driving the baffle plate 40 to vertically raise and lower.

[0025] In one specific embodiment, the third drive unit 70 includes a linear module for driving the suction unit to move toward the guide frame 20.

[0026] In one specific embodiment, the fourth drive unit 90 includes a connecting frame 901 mounted on one side of the guide frame 20 and a first cylinder 902 mounted on the connecting frame 901; the arc-shaped guide plate 80 is connected to the first cylinder 902 and is used to move as needed on the outlet side of the guide frame 20 under the drive of the arc-shaped guide plate 80.

[0027] In one specific embodiment, the unpacking mechanism includes a bottom sealing unit 100 installed in the mounting base 10 for sealing the bottom of the carton after unpacking, and a fifth driving unit 200 connected to the bottom sealing unit 100 for driving the bottom sealing unit 100 to move within the mounting base 10.

[0028] Specifically, in this embodiment, the bottom sealing unit 100 seals the bottom of the carton, and the fifth driving unit 200 moves the bottom sealing unit 100 so that it can be centered at the bottom of the carton according to its size, thus enabling the sealing of the bottoms of different cartons. It should be noted that the bottom sealing unit 100 is an application of existing technology and will not be described further here. Furthermore, the fifth driving unit 200 includes a sliding plate 2001 slidably mounted in the mounting base 10, and a second cylinder 2002 connected to the sliding plate 2001 for driving its movement; the bottom sealing unit 100 is mounted on the sliding plate 2001.

[0029] The case opening mechanism of the case opening machine involved in this utility model, through the first drive unit 30, the second drive unit 50 and the fourth drive unit 90, can adjust the position of the guide frame 20 and the arc guide plate 80 as needed according to the size of the carton to be opened, thereby effectively adapting to various carton sizes to be opened and improving the practicality of the case opening machine.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
