Detailed ways

In order to easily understand the technical means, creation features, achievement goals and effects of the present utility model, the present utility model is further described below with reference to the specific figures.

As shown in Figures 1-4, an unpacking machine includes a vertical cardboard storage line 1, a main body frame 2, a bottom folding mechanism 3 and a bottom sealing mechanism 4, and two parallel pressure plates 11 are arranged inside the main body frame 2. Two pressing plates 11 are located at the exit of the vertical cardboard storage line 1, and both are arranged perpendicular to the direction of the vertical cardboard storage line 1. One pressing plate 11 is fixedly connected to the main frame 2 through the bracket 12, and the other pressing plate 11 is The telescopic cylinder 13 is connected with the main body frame 2, the upper end of the main body frame 2 is fixedly connected with a guide rail 5, and the guide rail 5 is arranged in parallel with the vertical cardboard storage line 1, and an electric slider 6 is slidably connected to the guide rail 5, and the bottom of the electric slider 6 is slidably connected. A second telescopic cylinder 7 is fixedly connected, and the telescopic end of the second telescopic cylinder 7 is installed with a box-supporting mechanism for pulling apart the cardboard.

With the above solution, firstly, the gap between the cardboards 10 is exposed by the pressing plate 11, and then the clamping plate 9 is driven to extend into the gap and hold one side of the cardboard 10, and then the clamping plate 9 moves laterally to pull the cardboard 10 into a carton. Compared with the suction cup , the splint 9 and the carton 10 will not fall off, and the working stability is good.

The box-supporting mechanism includes a clamping jaw cylinder 8 and two clamping plates 9. The top of the clamping jaw cylinder 8 is fixedly connected to the telescopic end of the second telescopic cylinder 7, and the two clamping jaw ends of the clamping jaw cylinder 8 are respectively fixed to the two clamping plates 9. connected, the two clamping plates 9 are located between the two pressing plates 11 .

With the above solution, the clamping plate 9 itself is relatively thin and can easily extend into the gap of the cardboard 10, and another clamping plate 9 clamps one side of the cardboard 10 from the outside of the cardboard 10, so that the cardboard 10 is firmly clamped and will not fall off halfway.

The initial width between the two pressing plates 11 is the same as the width of the vertical cardboard storage line.

With the above solution, the width between the two pressing plates 11 is the same as the width of the cardboard 10 in the initial state, so as to prevent the pressing plates 11 from excessively pressing the two sides of the cardboard 10 and causing the cardboard 10 to be twisted and deformed.

Working principle: When in use, the cardboard 10 enters between the two pressing plates 11 in the main frame 2 through the vertical cardboard storage line 1, and then one of the pressing plates 11 slightly squeezes the cardboard 10 under the drive of the first telescopic cylinder 13, so that The cardboard 10 stands up to open the gap according to the folding line, and then the clamping plate 9 is driven by the first telescopic cylinder, one of the clamping plates 9 extends into the gap of the cardboard 10, and the other clamping plate 9 is located outside the cardboard 10. Next, the two splints 9 are close to each other to clamp the cardboard 10, and then the electric slider 6 traverses on the guide rail 5 to drive the splint 9 to move laterally, and the splint 9 drives the cardboard 10 to pass through the pressing rod, so that the cardboard 10 is erected and stretched open. The carton is then passed through the bottom folding mechanism 3 and the bottom sealing mechanism 4 in sequence to complete the unpacking operation.

The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited by the above-mentioned embodiments, and without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements are within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
