DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 5As shown, the utility model discloses a box-gluing machine unloading device, including a box-gluing machine body 1, a conveying frame 2 is fixedly connected to one side of the box-gluing machine body 1, a driving roller 21 driven by a motor is rotatably connected to the conveying frame 2, and a conveyor belt 22 is rotatably connected to the driving roller 21. Further, the conveying frame 2 is fixedly connected to a mounting frame 3 above the conveyor belt 22, and an output belt for conveying paper boxes is provided on the box-gluing machine, and a transition inclined plate 7 is fixedly connected between the output belt and the conveyor belt 22. Since there is a height difference between the output belt and the conveyor belt 22 in this embodiment, the transition inclined plate 7 can smoothly connect the conveyor belt and the conveyor belt 22, ensuring that the paper box will not roll or even fall off the conveyor belt 22 when it is transitioned to the conveyor belt 22. Furthermore, a lifting cylinder 31 is fixedly connected to the mounting frame 3, and a baffle 32 for blocking the paper box is fixedly connected to the piston rod of the lifting cylinder 31, and limiting grooves 33 are symmetrically provided on the inner side wall of the mounting frame 3, and the baffle 32 is slidably connected in the limiting grooves 33, thereby ensuring that the baffle 32 can remain stable when it moves up and down frequently; and a screening component for screening unqualified paper boxes is cooperatively arranged between the mounting frame 3 and the baffle 32, and in addition, a collection frame 4 is fixedly connected to the end of the conveying frame 2 away from the main body 1 of the box gluing machine, and a lifting and collecting mechanism for collecting qualified paper boxes is cooperatively arranged in the collection frame 4.

[0026] The working principle of the utility model is as follows: when the pasted paper box is transferred to the conveying rack 2 by the box-gluing machine body, the lifting cylinder 31 drives the shielding plate to descend to intercept the paper box, and then the screening component detects and screens the shape of the paper box. Unqualified paper boxes will be pushed off the conveyor belt 22 by the screening component. If the paper box passes the inspection, the shielding plate will rise to leave a gap for the paper box to pass through, and the qualified paper box will be transported to the lifting and collecting mechanism via the conveyor belt 22.

[0027] Among them, the screening component includes a push plate 51, a reciprocating screw rod 52 driven by a motor and a detection camera 53. The specific structure of the screening component is: two mounting plates 54 are symmetrically arranged at the lower end of the side wall of the baffle plate 32 facing the gluer body, the reciprocating screw rod 52 is rotatably connected between the mounting plates 54, the push plate 51 is threadedly connected to the reciprocating screw rod 52, and the lower end of the push plate 51 is flush with the lower end surface of the baffle plate, the mounting frame 3 is fixedly connected with a cross plate 55 above the push plate 51, the detection camera 53 is fixedly connected to the lower end surface of the cross plate 55, and the detection camera 53 faces the gluer body; further, the conveying frame 2 is symmetrically provided with material taking ports 23 on the two side walls close to the gluer body 1, and the conveying frame 2 is provided with a feeding ramp 24 at the lower end of the material taking port 23.

[0028] The working principle of the screening component is as follows: when the carton is conveyed to the conveyor belt 22 by the box-gluing machine body, the baffle plate 32 descends and contacts the upper end of the conveyor belt 22, and the detection camera 53 first performs a quick visual inspection of the shape of the carton. If it is detected that the shape of the carton does not meet the standard, the baffle plate 32 will not rise, and the unqualified carton will be pushed off the conveyor belt 22 through the reciprocating linear motion of the push plate 51 on the reciprocating screw 52, ​​without the need to manually remove the unqualified carton; if the carton passes the inspection, the baffle plate 32 will be lifted upward to leave enough space for the carton to pass through, thereby completing the screening of the carton and improving the quality of each batch of products.

[0029] Furthermore, the lifting and collecting mechanism includes a transmission screw 61 driven by a servo motor, at least one limit rod 62 and a collection seat 63. The specific connection method of the lifting and collecting mechanism is: the transmission screw 61 is rotatably connected to the collection frame 4, the collection seat 63 is threadedly connected to the transmission screw 61, the limit rod 62 is fixedly connected to the side of the transmission screw 61, the collection seat 63 is slidably connected to the transmission screw 61, a collection box 64 for collecting paper boxes is placed on the collection seat 63, and a sensitive weighing sensor 65 is fixedly connected to the lower end surface of the collection seat 63.

[0030] The working principle of the lifting and collecting mechanism is as follows: the paper boxes that have passed the inspection are conveyed to the collecting seat 63 by the conveyor belt 22. After the sensitive weighing sensor 65 of the collecting seat 63 detects the weight change on the collecting seat 63, the servo motor drives the collecting seat 63 to move downward. As the number of paper boxes on the collecting seat 63 increases and the weight of the collecting seat 63 increases, the collecting seat 63 gradually moves downward until the collecting seat 63 moves to the lowest end and contacts the collecting frame 4. Then the worker takes the collecting box 64 off the collecting seat 63 and pours it into another container.

[0031] It should be noted here that in this embodiment, there are a lot of mature technologies to support the functions to be achieved by the detection camera 53 and the weight sensor. The essence of the utility model is to optimize the combination of existing hardware machine connection methods for specific application scenarios to adapt to the problems of how to screen and collect cartons (without changing the internal structure of the detection camera 53 and the sensitive weighing sensor 65).
