[0043] Example 1

[0044] like Figures 1-4 As shown,

[0045] A cigarette filling and packaging integrated machine, comprising a box opening and feeding device and a cigarette packing and filling device, wherein:

[0046] The box opening and feeding device includes:

[0047] A conveyor belt is installed in the empty box feeding channel. The conveyor belt is used to place empty wooden boxes 1 and can transport the empty wooden boxes 1 in an orderly manner. A drive motor and a pulley for driving the conveyor belt are also installed in the empty box feeding channel. Driven by the drive motor and the pulley, the conveyor belt can run in the empty box feeding channel and can transport the empty wooden boxes 1 placed on the conveyor belt in an orderly manner. When the empty wooden boxes 1 are placed on the conveyor belt, the box cover 6 is placed downward and the box bottom is placed upward.

[0048] The empty box clamping and conveying device is arranged at the rear of the conveyor belt, and is used to clamp the two sides of the empty wooden boxes 1 conveyed from the conveyor belt, and convey the empty wooden boxes 1 to the open cover station suspended below. The empty box clamping and conveying device can convey the empty wooden boxes 1 conveyed from the conveyor belt one by one without opening the box lid 6 by clamping the two sides of the box body to the open cover station suspended below for opening the box lid 6.

[0049] The negative pressure box lid opening device is located below the empty box clamping and conveying device. When the empty wooden box 1 is clamped and conveyed to the lid opening station, the negative pressure box lid opening device sucks the box lid 6 by negative pressure and drives the box lid 6 downward to open. The box lid 6 remains open under the action of gravity, and the desiccant in the empty wooden box 1 falls under the action of gravity.

[0050] The negative pressure box lid opening device adopts a crank connection mechanism. Specifically, the negative pressure box lid opening device includes a flywheel 2, a crankshaft 3, a connecting rod 4 and a negative pressure suction cup 5. The flywheel 2 is connected to the driving device. One end of the connecting rod 4 is connected to the crankshaft 3 set on the flywheel 2. The other end of the connecting rod 4 is rotatably connected to the negative pressure suction cup 5. The negative pressure suction cup 5 is connected to the negative pressure pipeline. When the empty wooden box 1 is clamped and transported to the lid opening station, the flywheel 2 and the crankshaft 3 rotate to drive the connecting rod 4 to rise. The negative pressure suction cup 5 adsorbs the box lid 6 under the action of negative pressure. Then, the flywheel 2 and the crankshaft 3 drive the connecting rod 4 to descend. The negative pressure suction cup 5 adsorbs the box lid 6 downward to open the box lid 6. Then, the negative pressure pipeline connected to the negative pressure suction cup 5 cuts off the negative pressure. The negative pressure suction cup 5 separates from the box lid 6. The box lid 6 remains open under the action of gravity, and the desiccant in the box also falls under the action of gravity.

[0051] In this embodiment, the feeding mechanism of the empty wooden box 1 is redesigned, and the currently commonly used front side facing upward is changed to the back side facing upward. The corresponding box cover 6 is opened downward, and the empty wooden box 1 is fed and conveyed by the clamping belts on both sides. After the empty wooden box 1 enters the equipment, when the box cover 6 is opened by the negative pressure box cover opening device composed of the crank connecting rod 4, after the box cover 6 is opened, the desiccant in the box falls under the action of gravity, and the desiccant is taken out at the same time.

[0052] After the box cover 6 is opened by the box opening and feeding device, the empty box continues to be conveyed to the next process under the conveying action of the empty box clamping and conveying device, and enters the cigarette packing and filling device.

[0053] A cigarette pack filling device comprising:

[0054] The empty box conveying guide rail 7 is provided in correspondence with the empty box clamping and conveying device, and is used to convey the empty wooden box 1 with the box cover 6 opened. The conveying direction of the empty wooden box 1 on the empty box conveying guide rail 7 is consistent with the length direction of the empty wooden box 1. The empty box conveying guide rail 7 conveys the empty wooden box 1 by clamping both sides of the empty wooden box 1. The empty box conveying guide rail 7 includes two parallel friction conveyor belts, which clamp the empty wooden box 1 and drive the wooden box forward.

[0055] The cigarette pack lifting push rod 8 is located below the empty box conveying guide rail 7 and is used to push the small cigarette packs that have been packed by the upstream packaging machine upwards into the empty wooden box 1 in groups of ten to complete the cigarette packing work;

[0056] The cigarette supporting plate 9 is located at the lower part of the empty box conveying guide rail 7. The height of the cigarette supporting plate 9 is consistent with the bottom height of the empty wooden box 1, and the height of the cigarette supporting plate 9 is at the same height as the highest point of the cigarette pack lifting push rod 8. The cigarette supporting plate 9 is located on both sides of the space above the cigarette pack lifting push rod 8. The empty space is used for the cigarette supporting plate 9 to fill ten small cigarette packs into the empty wooden box 1; the function of the cigarette supporting plate 9 is to replace the support function of the cigarette pack lifting push rod 8 when the empty wooden box 1 and the cigarette pack move forward beyond the support range of the cigarette pack lifting push rod 8; the cigarette supporting plate 9 located in front of the cigarette pack lifting push rod 8 can also play the role of supporting the empty wooden box 1;

[0057] After the cigarette pack lifting push rod 8 fills the cigarette packs into the empty wooden box 1, it temporarily stops moving to ensure that the cigarette packs are positioned in the empty wooden box 1, while the empty box conveying guide rail 7 continues to drive the empty wooden box 1 and the ten small packs of cigarette packs inside to move forward together; and they are kept inside the empty wooden box 1 under the support of the cigarette supporting plate 9.

[0058] The box cover support rod 10 is provided corresponding to the empty box clamping and conveying device, and is used to support the box cover 6 to keep the box cover 6 in an open state;

[0059] The folding plate 11 has a gradually curved arc structure, which bends from one side of the box cover 6 to the side away from the box cover 6, and the height of the folding plate 11 gradually rises to the height of the bottom of the empty wooden box 1. The folding plate 11 is corresponding to the box cover support rod 10. There is a gap at one end between the folding plate 11 and the box cover support rod 10. After the box cover 6 leaves the box cover support rod 10, it returns to a vertical state under the action of gravity, and enters the inner side of the folding plate 11 with the transmission of the empty box clamping and conveying device. The closing of the box cover 6 is gradually completed through the bending structure of the folding plate 11, and the packaging of the wooden box is completed. The wooden box that has completed folding and packaging is conveyed to the next process to continue the next packaging process.

[0060] The present invention addresses the shortcomings of the current wooden box filling method. In order to solve the problems of the traditional filling method, where the empty wooden box 1 is placed at the bottom and the cigarette packs to be loaded are placed at the top, the cigarette packs are easily scattered at the flap opening when filling from top to bottom, the device has poor stability, and is difficult to adjust, the present invention adopts an inverted box filling method. The empty wooden box is placed upside down on the cigarette packs, and ten small packs of cigarette packs are loaded into the empty box from bottom to top using a push rod. The box then closes the box lid 6 as it moves forward in a translation, thereby achieving the purpose of packaging ten small packs of cigarette packs.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
