[0005] By adopting the above technical solution, when the disposable tableware needs to be repackaged, the disposable packaging bags are transported to the silo position one by one by the feeding device, and the sensing device senses the number of disposable tableware dropped to the silo position. When the number of disposable tableware on the silo reaches the set number, the pushing device on the silo will transport the disposable packaging bags in the silo to the packaging device for secondary packaging. The silo is placed in the secondary packaging bag, so that the packaging film on the packaging film receiving roller is transported to the former position, and then folded inward along both sides of the silo and gathered into a bag shape by the former, and sent to the longitudinal sealing machine. The air inlet duct is arranged so that after one end of the secondary packaging bag is sealed, air can be blown along the direction of the inlet position of the secondary packaging bag through the air inlet duct to open the bag body of the secondary packaging bag, and then a certain amount of disposable tableware is pushed into the secondary packaging bag through the pushing device, so that feeding is more convenient. After the disposable packaging bag with a certain amount is filled, the secondary packaging bag is finally sealed and cut through the transverse sealing mechanism to complete the secondary packaging of the disposable tableware, thereby reducing the workload of personnel and improving work efficiency.

[0011] By adopting the above technical solution, the setting of the guide mechanism enables the guide rod to extend along the guide channel position and move along the pushing direction of the push plate when the first driving mechanism drives the push plate to push the material. When the first driving mechanism drives the push plate to reset, the guide rod also moves into the guide channel along the moving direction of the first driving mechanism to guide the pushing of the material, thereby making the operation of the first driving mechanism more stable. One or more guide rods may be provided, and the number of the guide channels matches the guide rods. Preferably, there are two guide rods, which are respectively provided on both sides of the first driving mechanism, and the structure is stable.

[0026] The present invention further provides that: a connecting block is provided on one side of the first pressing part corresponding to the discharge direction, and a needle rod is provided on one side of the connecting block corresponding to the second pressing part.

[0027] By adopting the above technical scheme, the needle bar is set, and the needle bar is set on the side of the first pressing part corresponding to the discharge direction, so that when the pressing part moves downward and matches the second pressing part to seal the secondary packaging bag, the needle bar moves with the movement of the first pressing part, and is used to puncture the secondary packaging bag and discharge the air in the secondary packaging bag, so that the sealing of the secondary packaging bag is smoother, and avoid the problem that there is too much air in the secondary packaging bag, resulting in bag bulging and damage to the secondary packaging bag. The needle bar can be operated once or multiple times. The present invention is preferably twice. The first time, the needle bar is driven by the first cylinder to move along the direction of the secondary packaging bag and puncture the upper surface of the secondary packaging bag and place it in the secondary packaging bag, which plays a material blocking role and avoids the return of disposable tableware that has been placed in the secondary packaging bag. The second time, when the first pressing part and the second pressing part move toward each other to seal, the needle bar moves with the first pressing part to puncture holes through the secondary packaging bag from top to bottom, so that the sealing is smoother and the air in the secondary packaging bag can be discharged.
