Box sealing mechanism convenient to operate

[0017] Example 1

[0018] Such as Figure 1-2 As shown, an easy-to-operate box sealing mechanism includes a box sealing bracket. The box sealing bracket includes two sets of conveying side frames 1. An auxiliary roller plate 2 is provided between the two sets of conveying side frames 1. A guide wheel 3 is provided above the roller plate 2, an upper box sealer 5 is provided above the auxiliary roller plate 2, a lower box sealer 6 is provided in the middle of the auxiliary roller plate 2, and the box sealing bracket includes The fixed side plate 4, the outer surface of the fixed side plate 4 is connected with a telescopic moving mechanism, the moving end of the telescopic moving mechanism is fixedly connected with an upper bracket, and the upper box sealer 5 is connected with the upper bracket. Generally speaking, The inner surface of the conveying side frame 1 is provided with a conveyor belt, and the side wall of the box body is clamped by the conveying side frame 1 to convey the box body. The upper box sealer 5 and the lower box sealer 6 are both commonly used box sealers. The upper end surface and the lower end surface of the body are sealed, and the telescopic moving mechanism can also adopt other telescopic moving mechanisms. In this embodiment, the following structure is adopted.

[0019] The upper bracket includes a moving side frame 12, the telescopic moving mechanism includes a No. 1 side post 10 and a No. 2 side post 11, and the outer surface of the upper end of the No. 1 side post 10 and the No. 2 side post 11 is connected with a fixed top plate 9 The first side post 10 and the second side post 11 both penetrate the moving side frame 12, and the moving side frame 12 moves up and down along the first side post 10 and the second side post 11; the telescopic moving mechanism includes a drive motor , The rotating end of the driving motor is connected with a screw 8, the outer surface of the upper end of the screw 8 is movably connected with the fixed top plate 9, the screw 8 can rotate relative to the fixed top plate 9, and the outer surface of the screw 8 is connected to the movable side frame 12 Threaded connection, through the drive motor to drive the screw 8 to rotate, prompting the mobile side frame 12 to move up and down along the side post 10, so as to adjust the position of the upper box sealer 5; to make the movement of the mobile side frame 12 more stable, make the following settings: The outer surface of the fixed side plate 4 is fixedly connected with a motor support 7 and the drive motor is located in the motor support 7; the outer surface of the lower end of the screw 8 is fixedly connected with a connecting gear 13, and the rotating end of the drive motor Connect with the chain of the connecting gear 13; set the motor support 7 and the drive motor on the other side of the fixed side plate 4, and use the chain drive connection at the same time, and the drive is relatively stable. The drive motor rotates the servo motor to meet the requirements of forward and reverse control. Yes, the specific model can be selected by the weight of the actual movable side frame 12, and there are no other restrictions.

[0020] Example 2

[0021] Such as image 3 As shown, on the basis of the above-mentioned embodiment 1, in order to make the moving side frame 12 connected to the upper box sealer 5 more stable in the up and down movement, the following improvements are made. The outer surface of the screw 8 and the first side Both the column 10 and the second side column 11 are connected by a chain. In this embodiment, the outer surfaces of the first side column 10 and the second side column 11 are both provided with threaded structures, and the first side column 10 and the second side column 11 Both are threadedly connected with the movable side frame 12. Specifically, two sets of gears of the same model as the connecting gear 13 can be fixed on the surface of the screw 8 and then connected by a chain. In actual use, since the three sets of gears are of the same model, the screw 8 and The rotation speed of the No. 1 side post 10 and the No. 2 side post 11 are the same, so the upward moving force of the moving side frame 12 is provided by the No. 1 side post 10, the second side post 11 and the screw 8 together, and the moving side frame 12 and the No. 1 side post 10, and the No. 2 side post 11 and the screw 8 are all connected by threads. At this time, the stability of the entire movable side frame 12 is greatly improved.
