after forming a regular packing bag shape, manually controlling linear drivers in the longitudinal plate 3a and the transverse plate 3b to enable the upper hot pressing strips 5 to extend downwards, carrying out hot pressing fusion on two layers of packing films by matching with the lower hot pressing strips 11 on the workbench 1004, and carrying out hot melting on two layers of packing films by the bonding heating areas of the upper hot pressing strips 5 and the lower hot pressing strips 11 to form a sealed packing bag to pack a tray, wherein the fusing heating area fuses the connection between the packing bag with each side completing hot melting sealing and the whole packing film, so that the packed tray forms each independent individual, and the simultaneous packing work of multiparty trays and the separation of each tray into independent packages are realized; after the tray is packed, redundant waste films remain in the area between the two roller bodies of the corresponding crease-removing roller set 4 on the workbench 1004, so that the next packing is affected, the waste films need to be removed, the whole waste films still form a plane state, and only the positions corresponding to the packing areas are divided by hot melting for packing, so that a plurality of holes are formed; firstly, the packed tray is required to be moved away to prevent the tray from being involved with the waste film, so that the tray is inconvenient to clean; at this time, the pressing plate group 3 is still at the pressing position, the air bags 6 are controlled to expand and deform manually, the air bags are covered on two sides of the packing tray and clamp the corresponding packing tray, the bulges on the surface of the air bags 6 squeeze the packing bag to deform to increase the clamping stability, after the clamping is stable, the first driving piece 103 is controlled to drive the pressing plate group 3 to drive the packing tray to move upwards, then the electric sliding block 102 is controlled to move forwards along the sliding rail 101 to bring the packing tray away from the workbench 1004, finally the first driving piece 103 is controlled to drive the pressing plate group 3 to drive the packing tray to move downwards, the air bags 6 contract to release the clamping of the packing tray, and the packed tray is placed on the bearing table to finish transferring;
then, cleaning the waste films, namely, because the temperature of the fusing heating area is higher than that of the bonding heating area and the temperature of air is lower when the fusing heating area is far away from the fusing heating area, an area with the temperature approximately equal to or higher than that of the bonding heating area exists in the direction that the fusing heating area is far away from the bonding heating area, and is also located at the part between the holes of the upper packaging film and the lower packaging film, so that the adhesion phenomenon is generated at the part between the holes of the upper packaging film and the lower packaging film, the upper film and the lower packaging film are separated by manually cutting the upper film at the adhesion part close to the outlets of the upper film and the lower film, so that the waste films and the new film are separated, the second driving piece 104 is controlled to drive the pulling roller set 8 to work, the adhered waste films are pulled downwards after passing through the waste port 1003, the waste films are intensively and uniformly cleaned from the workbench 1004, the waste films of the upper and lower packaging films are not required to be cleaned respectively, and the new lower packaging films are sent out and are covered on the surface of the workbench 1004 again for the next packaging, and the continuity of packaging work is ensured.
Example 2
On the basis of the embodiment 1, as shown in fig. 4 and 9-11, the sucker 201 and the supporting plate 301 are further included; a plurality of suckers 201 are arranged on the rear side of each longitudinal plate 3 a; the rear side of the bracket 1 is rotationally connected with a supporting plate 301 through a torsion spring; the pallet 301 is located at the lower side of the upper winding roller 1001, the upper punching envelope led out by the upper winding roller 1001 is in contact with the surface of the pallet 301, and the pallet 301 is higher than the pallet to be packed when in a horizontal state.
Also included is an automatic cutter 302; an automatic cutter 302 is arranged at the rear side of the middle vertical plate 3 a; the automatic cutter 302 is located on the front side of the suction cup 201.
The application method of the intelligent packaging equipment for the disposable food plastic trays comprises the following working steps:
s1: covering a lower packaging film on the workbench 1004, placing a tray to be packaged on the lower packaging film, and covering the upper side of the tray to be packaged with the upper packaging film;
s2: the upper packing film and the lower packing film are attached through the pressing plate group 3, and the crease removing roller group 4 removes the crease generated by pressing the upper packing film;
