Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding structure of a flat pushing chute of an unpacking machine. Background Art
[0002] At present, in the product packaging workshop, the produced cartons are generally in a folded state and need to be unpacked by an unpacking machine to be unfolded into a box body. In the prior art, in order to facilitate the unpacking machine to unpack, a flat pushing chute is generally arranged in front of the unpacking machine to facilitate stacking the cartons together. As the unpacking machine works, the cartons are gradually fed to the unpacking machine. Compared with the traditional independent horizontal feeding of cartons, the feeding efficiency can be effectively improved.
[0003] However, on the existing flat pushing chute, since the cartons are all in a vertical state and stacked together in the horizontal direction, when the cartons in the flat pushing chute are used up later, it is necessary to manually send the stacked cartons onto the flat pushing chute for replenishment operation, which is rather troublesome to operate and there is a problem of low replenishment efficiency.
[0004] Therefore, we propose a feeding structure of a flat pushing chute of an unpacking machine to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a feeding structure of a flat pushing chute of an unpacking machine to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A feeding structure of a flat pushing chute of an unpacking machine includes a counterweight base, a fixed clamping plate and a movable clamping plate. A rotary table is rotatably installed on the counterweight base, and a telescopic member is installed on the rotary table. The top end of the telescopic member is connected with a top frame. The fixed clamping plate is fixedly connected with the top frame, and the movable clamping plate is movably connected with the top frame. A pair of main gears are coaxially and rotatably installed inside the top frame, and a motor one for driving the main gears to rotate is installed on the side of the top frame. The top end of the movable clamping plate is connected with a rack bar through a cross bar. The rack bar penetrates through the inside of the top frame and is meshed with the main gear.
[0008] In a further embodiment, a motor two is installed inside the counterweight base, and the output shaft of the motor two is connected with the rotary table.
[0009] In a further embodiment, a plurality of steel balls are rotatably embedded on the upper surface of the counterweight base, and the parts of the steel balls protruding from the upper surface of the counterweight base are closely attached to the inner top surface of the rotary table.
[0010] In a further embodiment, convex rib strips are provided on the inner top surface of the top frame, and strip grooves matching the convex rib strips are provided on the upper surface of the rack bar.
[0011] In a further embodiment, a guide rod parallel to the telescopic direction of the telescopic member is further installed on the rotary table, and a limit sleeve sliding along the guide rod is installed on the top frame.
[0012] In a further embodiment, a plurality of transverse anti-slip strips are provided on the opposite surfaces of the fixed clamping plate and the movable clamping plate, and the transverse anti-slip strips are arranged at equal intervals along the length direction of the clamping plate.
[0013] In a further embodiment, the telescopic member is one of a cylinder, a hydraulic cylinder, and an electric push rod.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] By arranging the fixed clamping plate and the movable clamping plate to cooperate, the present utility model can automatically clamp the stacked cartons. Then, by extending the telescopic member, the fixed clamping plate and the movable clamping plate clamp the cartons and lift them to a height higher than the flat pushing chute.

[0025] Please refer to Figure 1-2, A feeding structure for the flat pushing material trough of an unpacking machine, including a counterweight base 1, a fixed clamping plate 5 and a movable clamping plate 6. A rotary table 2 is rotatably installed on the counterweight base 1, and a telescopic member 3 is installed on the rotary table 2. The telescopic member 3 can be, but is not limited to, one of a cylinder, a hydraulic cylinder, and an electric push rod. It telescopically moves in the vertical direction. The top end of the telescopic member 3 is connected to a top frame 4, so as to drive the top frame 4 to lift and lower through the telescopic member 3. And a pair of fixed clamping plates 5 are provided, and the fixed clamping plates 5 are respectively fixedly connected to the side edges of the top frame 4. A pair of movable clamping plates 6 are also provided corresponding to the fixed clamping plates 5, and are movably connected to the top frame 4, so as to adjust the distance between the movable clamping plate 6 and the fixed clamping plate 5, thereby clamping the stacked cartons. A pair of main gears 7 are coaxially rotatably installed inside the top frame 4. This pair of main gears 7 are connected by a connecting rod, and a motor one 8 for driving the main gear 7 to rotate is also installed on the side edge of the top frame 4. The main body part of the motor one 8 is fixed to the side edge of the top frame 4, and the output shaft of the motor one 8 is coaxially connected to the main gear 7. The tops of a pair of movable clamping plates 6 are connected by a cross beam rod 10, and a rack rod 9 is connected to the side of the cross beam rod 10. The rack rod 9 penetrates through the inside of the top frame 4 and is meshed with the main gear 7, so that when the main gear 7 rotates, it drives the rack rod 9 to move, and further realizes the adjustment of the distance between the movable clamping plate 6 and the fixed clamping plate 5.
[0026] Please refer to Figure 3 , To facilitate the rotation of the rotary table 2, a motor two 13 is installed inside the counterweight base 1, and the output shaft of the motor two 13 is connected to the rotary table 2. The rotary table 2 is driven to rotate by the motor two 13, so that after the whole mechanism clamps the carton from one position, it can then rotate to a position directly facing the flat pushing material trough and put down the carton.
[0027] Please refer to Figure 3 , Further, a number of steel balls 14 are rotatably inlaid on the upper surface of the counterweight base 1, and the part of the steel balls 14 protruding from the upper surface of the counterweight base 1 is in close fit with the inner top surface of the rotary table 2.
