Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a wet tissue packaging machine. Background Art

[0002] At present, as a sanitary product, wet tissues are widely used, such as in families, hotels, restaurants, traveling, etc., and are gradually favored by people for their convenience. During the production process of wet tissues, they need to be packaged by a packaging machine.

[0003] A Chinese patent with the authorization announcement number CN216443957U discloses a wet tissue packaging machine, which includes a conveying assembly. The conveying assembly includes a first conveying frame and a first conveyor belt. The first conveyor belt is connected to the first conveying frame and is used for conveying wet tissues. Above the first conveyor belt, there is a pressing assembly. The pressing assembly includes a second conveying frame and a second conveyor belt. The second conveyor belt is located on the second conveying frame and circulates. It can reduce the air between the packaging bag and the wet tissue and reduce the influence of air on the quality of the wet tissue.

[0004] However, when the above-mentioned packaging machine discharges the air between the top surface of the packaging bag and the wet tissue, due to the dust or dirt that is likely to accumulate on the surface of the second conveyor belt during long-term use, its use effect will be affected. At this time, the packaging machine needs to stop working, and then wait for the staff to clean the second conveyor belt before it can continue to work, which greatly reduces the packaging efficiency of the wet tissue. Summary of the Utility Model

[0005] Aiming at the problems in the background art, a wet tissue packaging machine is proposed. By arranging two groups of pressing assemblies and a transposition mechanism above the conveyor belt, the transposition mechanism can transpose the two groups of pressing assemblies when cleaning is needed, without the need to stop the machine for treatment, improving the working efficiency of the wet tissue packaging machine.

[0006] The utility model provides a wet tissue packaging machine, including

[0007] A frame, on which a conveyor belt a for conveying un-sealed wet tissue packages is drivingly arranged, and at one end thereof, there is a hot pressing and cutting mechanism for sealing the wet tissue packages;

[0008] A fixed frame is arranged on the frame, and inside it, there are two groups of pressing assemblies for flattening the wet tissue packaging bags from above and a transposition mechanism for driving the two groups of pressing assemblies to switch positions.

[0009] Preferably, the pressing assembly includes a movable frame and a conveyor belt b, which is arranged in a U shape. At the opening of its lower end surface, a conveyor belt b is drivingly connected. When the conveyor belt b conveys the wet tissue packaging bag, its lower end surface is in contact with the upper end surface of the wet tissue packaging bag.

[0010] Preferably, the transposition mechanism comprises a threaded rod, a movable plate, a guide member and a synchronous driving member, wherein two groups of threaded rods are provided and are arranged to rotate side by side inside the fixed frame, and a synchronous driving member for driving the two groups of threaded rods to move synchronously is provided between the two groups of threaded rods;

[0011] The two groups of threaded rods are both threadedly connected with movable plates, the two groups of movable plates are both slidably connected with the fixed frames through guide pieces, and the two groups of movable plates are respectively connected with the two groups of movable frames.

[0012] Preferably, the synchronous drive component includes a drive motor, a pulley and a belt. The drive motor is installed on the outside of the fixed frame, and its output end is connected to one group of threaded rods. Two groups of pulleys are provided, which are respectively connected to the ends of the two groups of threaded rods away from the drive motor. A belt is provided for transmission between the two groups of pulleys.

[0013] Preferably, the guide member comprises a guide rod, two ends of which are respectively connected to two sides of the inner wall of the fixing frame, and the guide rod is slidably connected to the movable plate.

[0014] Preferably, the two groups of threaded rods are respectively provided with left-handed threads and right-handed threads arranged in opposite directions to each other.

[0015] Through the above technical scheme, that is, the wet wipes packaging machine disclosed by the utility model, two groups of pressing components and a shifting mechanism are arranged above the conveyor belt. One group of the two pressing components is in use and the other group is in standby. When there is a lot of dirt accumulated on the surface of the pressing component in use, the two groups of pressing components are driven to shift positions by the shifting mechanism. The pressing component with more dirt can be moved aside, and the unused pressing component can be moved to the top of the conveying line. The pressing component that needs to be cleaned can be cleaned without stopping the machine for processing, thereby improving the working efficiency of the wet wipes packaging machine.

[0021] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0022] Embodiment 1

[0023] As Figure 1-Figure 3 shown, a wet wipe packaging machine proposed by the present utility model includes a frame 1, a pressing component of a fixed frame 4, and a transposition mechanism. A conveyor belt a 2 for conveying the unsealed wet wipe packaging is drivingly arranged on the frame 1, and a hot pressing and cutting mechanism 3 for sealing the wet wipe packaging is arranged at one end thereof. A fixed frame 4 is arranged on the frame 1, and two groups of pressing components for flattening the wet wipe packaging bag from above and a transposition mechanism for driving the two groups of pressing components to switch positions are arranged inside the fixed frame 4.

[0024] Among them, the two groups of pressing components are in a misaligned state. One group of pressing components is located directly above the conveyor belt a 2 to press the packaging bag on the conveyor belt a 2, and the other group of pressing components is located on one side of the conveyor belt a 2.

[0025] Among them, the hot pressing and cutting structure can be the high-frequency welding mechanism hot pressing and cutting in the Chinese utility model with the publication number of CN216443957U to form the packaged wet wipe finished product.

[0026] As Figure 1 shown, the pressing component includes a moving frame 5 and a conveyor belt b 6, which is arranged in a U shape, and a conveyor belt b 6 is drivingly connected to the opening at the lower end surface thereof. When the lower end surface of the conveyor belt b 6 conveys the wet wipe packaging bag, it is in contact with the upper end surface thereof.

[0027] Among them, the relative side of the conveyor belt b 6 and the conveyor belt a 2 is used to press the top surface of the packaging bag, and the conveying direction of the conveyor belt b 6 is the same as that of the conveyor belt a 2.

[0028] Embodiment 2

[0029] As Figure 1-Figure 3 shown, a wet wipe packaging machine proposed by the present utility model further details the specific components of the transposition mechanism and its connection method to the pressing component on the basis of the above embodiment.

[0030] As Figure 2 and Figure 3As shown, the shifting mechanism includes a threaded rod 7, a movable plate 8, a guide and a synchronous driving member. Two groups of threaded rods 7 are provided, which are rotatably arranged side by side on the inner side of the fixed frame 4, and a synchronous driving member for driving the two groups of threaded rods 7 is provided between the two groups of threaded rods 7; the two groups of threaded rods 7 are both threadedly connected with a movable plate 8, and the two groups of movable plates 8 are both slidably connected to the fixed frame 4 through the guide, and the two groups of movable plates 8 are respectively connected to the two groups of movable frames 5.

[0031] like Figure 3 As shown, the synchronous drive component includes a drive motor 9, a pulley 10 and a belt 11. The drive motor 9 is installed on the outside of the fixed frame 4, and its output end is connected to one group of threaded rods 7. Two groups of pulleys 10 are provided, which are respectively connected to the ends of the two groups of threaded rods 7 away from the drive motor 9. A belt 11 is provided between the two groups of pulleys 10 for transmission.

[0032] like Figure 3 As shown, the guide member includes a guide rod 12, both ends of which are respectively connected to the two sides of the inner wall of the fixed frame 4, and the guide rod 12 is slidably connected to the movable plate 8. The moving trajectories of the two groups of movable plates 8 are limited by the guide rod 12 to ensure the stability of their movement.

[0033] like Figure 3 As shown, the two groups of threaded rods 7 are respectively provided with left-handed threads and right-handed threads arranged in opposite directions, so that when the two groups of threaded rods 7 rotate in the same direction under the action of the synchronous driving member, they will drive the two groups of moving plates 8 to move in opposite directions, thereby replacing the two groups of moving frames 5.

[0034] In summary, when the utility model is in use, after the packaging bag with unsealed ends is wrapped with wet wipes, it enters from the feeding end of the frame 1 and is transported by the conveyor belt a2. When the packaging bag passes the movable frame 5 located directly above the conveyor belt a2, the corresponding conveyor belt b6 presses against the top of the packaging bag to make the packaging bag close to the top surface of the wet wipes, thereby squeezing the packaging bag and expelling the air between the top surface of the packaging bag and the wet wipes. When the conveyor belt b6 located directly above the conveyor belt a2 needs to be cleaned, the driving motor 9 works to drive one of the threaded rods 7 to rotate, and then the cooperation of the pulley 10 and the belt 11 can drive the other threaded rod 7 to rotate synchronously. Since the threads on the two threaded rods 7 are opposite, the two movable plates 8 will move in opposite directions, thereby driving the two movable frames 5 to drive the conveyor belt b6 to move in opposite directions, thereby facilitating the switching of the use positions of the two conveyor belts b6, so that while the corresponding conveyor belt b6 is being cleaned, the packaging bag can continue to be squeezed by the other conveyor belt b6, so there is no need to stop the machine for cleaning, thereby improving the overall packaging efficiency.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
