Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1

[0018] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: an empty box conveying mechanism for a drop-type packing machine, which includes a lower conveying frame 1. Upper conveying frames 2 are fixed on the surfaces of both side edges of the lower conveying frame 1. The lower conveying frame 1 is used for transporting empty boxes, and the upper conveying frames 2 are used for transporting water bottles. Moreover, an installation frame 3 is fixed on the side edges at one end of the lower conveying frame 1 and the upper conveying frames 2. A movable conveying frame 4 is slidably connected to the surface of the installation frame 3. Counting sensors 5 and photoelectric sensors 6 are respectively and fixedly connected to the surfaces of the upper conveying frame 2 and the movable conveying frame 4. The function of the counting sensor 5 is to record the number of water bottles passing through. When the number of passing water bottles reaches a predetermined amount, it is convenient for the control box to operate the second electric telescopic rod 16 at an appropriate time, so that the fixed clamping plate 14 and the movable clamping plate 15 clamp the water bottles. The function of the photoelectric sensor 6 is to detect whether there is an empty box passing through on the movable conveying frame 4. When there is an empty box passing through, it is convenient for the control box to timely stop the lower conveying frame 1 and the movable conveying frame 4 from conveying the empty boxes. A first electric telescopic rod 10 is fixedly connected to the surface of the installation frame 3 at the position of the support leg, and one end of the first electric telescopic rod 10 is fixedly connected to the side edge of the movable conveying frame 4. The first electric telescopic rod 10 plays a role in controlling the up and down movement of the movable conveying frame 4. A motor 11 is fixedly connected to the top side of the installation frame 3. A lead screw 12 is fixed to the output end of the motor 11, and the lead screw 12 is rotatably penetrated through the installation frame 3. A movable block 13 is threadedly connected to the surface of the lead screw 12, and the movable block 13 is slidably penetrated through the installation frame 3. Through the cooperation of the motor 11 and the lead screw 12, it is convenient to control the movement of the movable block 13, and further facilitate moving the water bottles clamped by the fixed clamping plate 14 and the movable clamping plate 15 to directly above the empty box on the movable conveying frame 4. A fixed clamping plate 14 is fixedly connected to the lower surface of the movable block 13 and a movable clamping plate 15 is slidably connected thereto, and a second electric telescopic rod 16 is fixedly connected to one end of the fixed clamping plate 14 and the movable clamping plate 15. Before the water bottles are clamped, the second electric telescopic rod 16 can prevent the water bottles from continuing to move forward and avoid the premature falling of the water bottles. When the number of water bottles meets the clamping amount, the second electric telescopic rod 16 contracts to make the fixed clamping plate 14 and the movable clamping plate 15 clamp the water bottles. A control box is provided on one side of the lower conveying frame 1.

[0019] Embodiment 2

[0020] As Figures 1-3As shown in the figure, on both side surfaces of the lower conveyor rack 1, the upper conveyor rack 2 and the movable conveyor rack 4, there are fixedly connected with an upper limit rack 7, a lower limit rack 8 and a movable limit rack 9 respectively. The upper limit rack 7 limits the position of the water bottles transported on the upper conveyor rack 2, facilitating the alignment of the water bottles with the position between the fixed clamping plate 14 and the movable clamping plate 15 for movement. The lower limit rack 8 and the movable limit rack 9 limit the positions of the empty boxes transported on the lower conveyor rack 1 and the movable conveyor rack 4, facilitating the alignment of the empty boxes with the water bottles clamped above when they move upward later. The free width between the upper limit racks 7 is adapted to the width of the packed items, and the free width between the lower limit rack 8 and the movable limit rack 9 is adapted to the width of the empty boxes. This ensures that while limiting, the resistance suffered during the transportation of water bottles and empty boxes is also reduced. Rubber anti-slip cushions are fixedly installed on the clamping surfaces of the fixed clamping plate 14 and the movable clamping plate 15, and with the help of the rubber anti-slip cushions, the stability of the fixed clamping plate 14 and the movable clamping plate 15 in clamping the water bottles is improved.

[0021] Working principle:

[0022] As Figures 1-3 shown in the figure, when the present utility model is in use, the lower conveyor rack 1 transports empty boxes. During the continuous transportation of the empty boxes on the lower conveyor rack 1, they will move onto the movable conveyor rack 4. When the movable conveyor rack 4 transports and moves the empty boxes, one side of the empty box will move into the sensing range of the photoelectric sensor 6. When the photoelectric sensor 6 senses that an object has passed, it will transmit its sensing data to the control box. After receiving the data, the control box will promptly close the lower conveyor rack 1 and the movable conveyor rack 4 to temporarily stop the transportation of the empty boxes.

[0023] The upper conveyor rack 2 transports water bottles. During the continuous transportation of the water bottles, they will pass through the counting sensor 5 one by one. The counting sensor 5 will count the passing water bottles. The passing water bottles will be blocked by the second electric telescopic rod 16 later to prevent them from moving forward continuously. When the number of passing water bottles reaches the predetermined quantity per batch on the counting sensor 5, the control box receives the data from the counting sensor 5, will first close the upper conveyor rack 2, and let the second electric telescopic rod 16 contract to clamp and fix the water bottles with the fixed clamping plate 14 and the movable clamping plate 15. After the second electric telescopic rod 16 finishes contracting, the control motor 11 is turned on to drive the lead screw 12 to rotate, so that the movable block 13 and the clamped water bottles move towards the mounting rack 3 side to above the empty boxes on the movable conveyor rack 4. When the movable block 13 finishes moving, the first electric telescopic rod 10 extends to make the movable conveyor rack 4 carry the empty boxes upward. After the first electric telescopic rod 10 extends, the second electric telescopic rod 16 extends to make the water bottles be smoothly loaded into the boxes.

[0024] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
