[0029] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] like Figure 1 The figure shows the overall structure of a cigarette pack box bundling device, which includes a mounting frame, a frame shell, and a dust removal device installed in the frame, etc. The above components are existing and therefore will not be described in detail. Figure 2 and Figure 3It is a schematic diagram of the structure after removing the above components, which consists of five modules including a loading and lifting module 100, a pushing and lifting shaping module 200, a laminated paper force module 300, a bundling and sealing module 400 and a discharging module 500.

[0031] Reference Figures 2 to 8 In combination with actual use, further explanation is given. The loading lifting cylinder 103 extends out to lift the loading lifting component 105, so that the height of the loading lifting component 105 is higher than the position of the synchronous belt 101. At this time, the loading state is set. The stacks of products 700 to be packaged are placed on the loading lifting component 105 manually or mechanically. In order to ensure the placement position, a loading side baffle 104 is installed on one side of the synchronous belt 101. The products 700 to be packaged can be placed against the loading side baffle 104. This is loading. After loading, the loading lifting cylinder 103 retracts and the height of the loading lifting component 105 drops to the same level as or lower than the position of the synchronous belt 101. At this time, the products 700 to be packaged fall on the synchronous belt 101, and the synchronous belt 101 is driven by the drive motor 102, driving the products 700 to be packaged to move forward to the push-lift shaping module 200.

[0032] Different from small cigarette packages, cigarette packages are large in size and heavy in weight when stacked, so they need to be shaped before bundling. The front end of the forward product 700 to be packaged touches the feeding sensor 204, and the feeding sensor 204 sends a signal to make the two push block cylinders 201-5 drive the push block 201-4 to move outward at the same time, and the product 700 to be packaged passes between the two push blocks 201-4. When the product 700 to be packaged passes the feeding sensor 204, the two push block cylinders 201-5 move inward at the same time, and the push cylinder 201-2 drives the mounting frame 201-1 to move forward along the push track 201-3. The push block 201-4 is against the rear end of the product 700 to be packaged and pushes it to the universal non-powered roller 202-3. While the push block 201-4 is pushing, the first shaping of the front and rear end surfaces of the product 700 to be packaged is completed, and the product 700 to be packaged enters the universal non-powered roller 202-3. When the powered roller 202-3 touches the feed sensor 205, the feed sensor 205 sends a signal, and the blocking cylinder group 202-2 extends out to block the forward movement of the product 700 to be packaged. At the same time, the shaping modules 203 installed on both sides of the universal non-powered roller 202-3 are actuated, and the shaping cylinder 203-1 extends out to push the shaping push plate 203-2 to perform a second shaping on the left and right sides of the product 700 to be packaged. After the shaping is completed, the shaping cylinder 203-1 and the blocking cylinder group 202-2 retract, and the lifting drive cylinder drives the base plate 202-1 and the components installed on the base plate 202-1 to move forward along the lifting drive track 202-5. The lifting drive cylinder is blocked in the figure and is not marked. The lifting cylinder 202-4 acts to adjust the height of the product 700 to be packaged, so that the product 700 to be packaged can accurately enter the limited paper pressing module 403 in the bundling and sealing module 400.

[0033] The bundling and sealing module 400 and the laminated paper tension module 300 are linkage working modules. The laminated paper 600 is mounted on the air expansion shaft 301-1, and one end is pulled out to bypass the tension roller 302-1 as shown in the figure to form a "W" shape and enter the guide roller 404. The guide roller 404 is arranged in multiple assembly positions to achieve the purpose of stretching and guiding the laminated paper 600 to pass through the upper paper pulling module 401, the limit paper pressing module 403 and finally reach the lower paper pulling module 402. The lower paper pressing cylinder 402-3 in the lower paper pulling module 402 is retracted, so that the lower paper The pressing plate 402-2 is pressed against the lower paper base plate 402-1 to press the coated paper 600 and tighten the coated paper 600. The product 700 to be packaged enters the limited paper pressing module 403, and its top is pressed against the coated paper 600 and continues to move forward. After moving forward to the right position, the side pressing plates 403-1 on both sides of the limited paper pressing module 403 are driven by the cylinder to press against the two sides of the product 700 to be packaged. At the same time, the top pressing block 403-2 is driven by the cylinder to press the coated paper 600 to the top of the product 700 to be packaged. At the same time, the upper paper pulling module 401 and the lower paper pulling module 402 are driven by the upper paper pulling motor 40 5 and the pull-down paper motor 406 drive synchronously to close to the position of the limited paper pressing module 403. After closing in place, the upper paper pressing cylinder 401-3 extends the upper paper pressing plate 401-2 to press the upper paper base plate 401-1 to press the laminated paper 600, the heating rod 401-4 heats the heating block 401-5, and the heating block driving cylinder 401-6 extends to push the heating block 401-5 to move to the closing position of the laminated paper 600 and heat-seal the closing position. After the heat sealing is completed, the heating block 401-5 retracts; when the pull-down paper module 402 moves from bottom to top, the package on it The cardboard 402-4 pushes the coated paper 600 to wrap along the outer edge of the product to be packaged 700. After the heat sealing is completed, the cutter cylinder 402-7 drives the knife holder 402-5 to move upward, and the cutter 402-6 installed on the knife holder 402-5 cuts the heat-sealed coated paper 600. At this time, the coated paper 600 without the external force shrinks and wraps the finished product. After cutting, the upper paper pressing cylinder 401-3 retracts, the upper paper pulling module 401 and the lower paper pulling module 402 are reset, and the limit paper pressing module 403 releases the packaged finished product, and the finished product enters the discharge module 500.

[0034] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
