However, before contacting the opening component, the packaging bag is in a free state and the opening direction of the packaging bag after shearing cannot be ensured. When the packaging bag is offset, the opening component will not be able to smoothly enter the opening of the package, causing the equipment to need to be shut down for maintenance. Summary of the Invention

[0005] In order to ensure that the opening direction of the packaging bag remains unchanged after the cutting is completed, so that the packaging bag can be smoothly opened by the opening assembly, thereby reducing the occurrence of shutdown for maintenance, the present application provides a wet wipes paper packaging machine.

The bag is packaged in a desired manner and is easily opened and closed by the user. The bag is packaged in a desired manner and is easily opened and closed by the user.

[0007] By adopting the above technical solution, the setting of the limiting component can limit the position of the packaging bag after the cutting component completes cutting, effectively preventing the packaging bag from being offset or changing position, ensuring that the opening direction of the packaging bag remains stable, and laying the foundation for the smooth operation of the subsequent opening component and the support component; the opening component and the support component are arranged in sequence on the side of the limiting component away from the cutting component, and the support component opens the packaging bag on the limiting plate along the width direction by adsorption. This design makes the opening process of the packaging bag more standardized and stable, facilitates the subsequent precise placement of wet wipes, and improves the efficiency and accuracy of packaging.

[0008] Optionally, the limiting plate is provided with an avoidance groove, which facilitates the opening component to contact the side wall of the packaging bag facing the limiting plate.

[0009] By adopting the above technical solution, the avoidance groove opened on the limiting plate provides a channel for the opening component to contact the packaging bag toward the side wall of the limiting plate, thereby avoiding the obstruction of the opening component operation by the limiting plate; the opening component can contact the packaging bag more smoothly and perform operations such as adsorption, thereby improving the convenience and reliability of the opening operation.

[0012] Optionally, the opening component includes a sliding bar, a sliding block, a linear motor, two rotating rods, two negative pressure tubes and a driving member. The length direction of the sliding bar is parallel to the distribution direction of the limiting component to the support assembly.

The negative pressure tubes are provided with adsorption holes. The two negative pressure tubes are respectively used to adsorb the opposite side walls of the packaging bag. The driving member is used to drive the two rotating rods to rotate simultaneously in the direction of approaching or moving away from the packaging bag.

[0013] By adopting the above technical solution, the sliding bar, sliding block and linear motor of the opening component can realize the movement of the negative pressure tube in the length direction, thereby realizing the separation of the packaging bag from the restriction component for subsequent opening operation; the two negative pressure tubes adsorb the opposite side walls of the packaging bag through the adsorption holes, and the driving member drives the rotating rod to rotate, thereby pulling the two side walls of the packaging bag apart to realize the opening; this structure can accurately control the position and size of the opening, ensure the stability and reliability of the opening operation, and effectively solve the problem of difficulty in opening due to the offset of the packaging bag in the prior art.

[0017] By adopting the above technical solution, the rotating plate of the opening opening assembly rotates driven by the rotating motor, so that the two opening opening members can work alternately between the opening assembly and the post-processing assembly. When one opening opening member is performing an opening operation at the opening assembly, the other opening opening member can simultaneously perform operations such as filling paper towels or sealing at the post-processing assembly, thereby realizing parallel processing of the processes and greatly improving the working efficiency of the packaging machine; the opening plates in the opening opening members are kept parallel by torsion springs, and the control member drives the opening plates to rotate toward each other. This design can facilitate the opening plates to enter the packaging bag in the open state.

The cylinder body of the sealing cylinder 724 is fixedly arranged on the sealing frame 721, the piston rod of the sealing cylinder 724 is fixed to the second sealing block 723, the electric heating block 725 is fixedly arranged on the second sealing block 723, the electric heating block 725 is used to increase the temperature of the second sealing block 723, the discharge conveyor belt 726 is parallel to the direction along the support member 53 to the sealing frame 721, the discharge conveyor belt is rotatably connected to the sealing frame 721, and the discharge conveyor belt 726 is used to transport the sealed wet wipes paper packaging bags to subsequent equipment.

[0048] The implementation principle of a wet wipe paper packaging machine in an embodiment of the present application is as follows: the staff first installs the rolled packaging bags onto the loading tray 21, and the packaging bags pass through the correcting part 22, the film pulling part 23, the length compensation part 24, the bottom sealing part 25, the marking part 26 and the film pulling part 23 in sequence. The correcting part 22 is used to adjust the position of the packaging bag, and the film pulling part 23 behind the correcting part 22 is used to pull the packaging bag and drive the packaging bag to move. The bottom plate sealing part 72 is used to perform a bottom sealing operation on the packaging bag, and the marking part 26 is used to perform a marking operation on the packaging bag. The film pulling part 23 behind the marking part 26 is used to control the length of the packaging paper entering the cutting component 3. Since the bottom sealing part 25 has the shrinkage of the packaging bag and there is a slippage between the film pulling part 23 and the packaging bag, it is ensured by the length compensation part 24 that the film pulling part 23 behind the marking part 26 can control the length of the packaging paper accurately.

[0049] The cutting component 3 is used to cut the packaging bag so that the packaging bag is independent and in a sealed state with a bottom plate. The opening component 4 is used to adsorb the two sides of the packaging bag to make the packaging bag open. The opening of the packaging bag is made more regular by the opening component 5, which is convenient for the subsequent placement of paper towels. The driving motor 462 drives the rotating plate 51 to rotate, so that the packaging bag in the opened state moves to the position of the rear pushing piece 71. The pushing block 712 sends the wet wipes into the opening of the packaging bag and makes the packaging bag detach from the opening piece 53. The packaging bag enters the sealing piece 72. The sealing piece 72 seals the opening of the packaging belt and sends it out of the packaging machine through the discharge conveyor belt 726.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
