[0031] Existing foods are usually packaged in a double-sealing manner. For example, block-shaped bread, shachima, etc., are unrolled along the food conveyor, and are rolled down and sealed on both sides when they are recovered and merged with the food. The whole is in a cylindrical shape, with the food inside, and then separated by a secondary seal through rotation to achieve sealed packaging of individual foods.

[0032] Based on the above, this embodiment, through the combination of the connecting member 21 and the fixing member 23, sets one end of the edge sealing member 22 in a rotatable manner and the other end in a final fixed manner on the upper shaft of the equipment body 1, and then connects with the inner cutting member 3, corresponding to the lower edge sealing assembly 4 below, to form a sealing and cutting component for food packaging. When replacing the inner cutting member 3, the edge sealing member 22 can be directly rotated on the basis of removing the fixing member 23, and rotated toward the outside of the equipment body 1 with the connecting member 21 as the rotation center, driving the inner cutting member 3 to turn to the outside of the equipment body 1, and then operate the inner cutting member 3 to separate from the heating part 24, and pull the inner cutting member 3 out of the edge sealing member 22 and the heating part 24, so as to realize the convenient replacement of the internal cutting knife of the packaging machine.

[0033] See also Figure 1-4 The device body 1 has symmetrical mounting holes on the rotating shaft, and the device body 1 is provided with a collar 25, which is located above the mounting hole on one side, and a connecting piece 21 is connected to the mounting hole, and the connecting piece 21 extends above the collar 25, and a locking piece 26 is provided on the connecting piece 21.

[0034] After the edge banding member 22 restricts its fixing member 23, it can be rotated by the connecting member 21. In this embodiment, the mounting holes on the upper shaft of the equipment main body 1 are all internal threaded holes, and the connecting member 21 is a rod with external threads. The connecting member 21 is inserted into the mounting hole to guide the edge banding member 22 close to the upper shaft. When the connecting member 21 is blocked, it rotates, and finally the edge banding member 22 is horizontally set above the upper shaft.

[0035] As for the extended end of the connecting member 21 , this embodiment combines a collar 25 with a locking member 26 which is preferably a nut to reinforce the connection between the connecting member 21 and the rotating shaft on the equipment body 1 , thereby improving the stability of the edge sealing member 22 .

[0036] One end of the edge banding member 22 is connected and fixed to the connecting member 21 and the upper shaft of the equipment body 1. In this embodiment, a connecting hole is opened on the edge banding member 22, and the connecting hole is aligned with the mounting hole on the other side. The fixing member 23 is arranged in the connecting hole and the mounting hole on the other side. After the edge banding member 22 is horizontally arranged, the connecting hole is aligned with the mounting hole on the other side, and then the fixing member 23, which is preferably a bolt, is rotated from top to bottom into the mounting hole and the connecting hole to complete the connection of the other end of the edge banding member 22 with the upper rotating shaft.

[0037] See also Figure 1-4The heating part 24 includes a connecting arm 241 arranged on the rotating shaft on the equipment body 1, a heating element 242 is arranged between the connecting arm 241 and the edge banding member 22, a slot is opened on the edge banding member 22, the slot and the heating element 242 are arranged on the same side, the inner cutting member 3 is arranged on the edge banding member 22 through the slot, and the inner cutting member 3 is connected to the heating element 242 through bolts.

[0038] Based on the conventional electric heating method of the packaging machine, the knife or edge banding plate sealing, the heating element 242 of this embodiment adopts an electric heating plate to surround the outer side of the sealing end of the edge banding piece 22, and the overall structure is designed as a clamp-like structure, fixed to the outside of the edge banding piece 22 by bolts, and then rotatably connected to the connecting arm 241. The edge banding piece 22 is heated by powering on the equipment main body 1, and then the packaging bag is sealed by the edge banding piece 22. After one end of the inner cutting piece 3 inserted into the edge banding piece 22 by the slot contacts the heating element 242, the inner cutting piece 3 passes through the waist hole opened at the other end, and the waist hole is adapted to the bolt fixing side of the heating element 242, and is just passed through by the bolt, so that the inner cutting piece 3 is fixed to the edge banding piece 22 through the heating element 242.

[0039] When replacing the internal cutting piece 3, first rotate the fixing piece 23 to release the restriction on one side of the edge banding piece 22, and then push the edge banding piece 22 to rotate on the rotating shaft on the equipment body 1 through the connecting piece 21, so that the connecting end of the internal cutting piece 3 and the heating element 242 is set to face outward, and then remove the bolts at the connection. The prepared hook tool can be inserted into the waist hole to pull the internal cutting piece 3 out from under the edge banding piece 22, so that the internal cutting knife of the equipment body 1 can be easily disassembled and assembled.

[0040] See also Figure 1-4 The lower edge sealing assembly 4 includes a sealing plate 41, a second connecting arm 42 and a second heating element 43. The sealing plate 41 and the second connecting arm 42 are both arranged on the lower rotating shaft of the equipment body 1. The second heating element 43 is arranged between the sealing plate 41 and the second connecting arm 42. A groove is opened on the sealing plate 41, and the internal cutting piece 3 is adapted to the groove.

[0041] Corresponding to the above-mentioned edge sealing piece 22 and internal cutting piece 3, the heating element 2 43 of the lower edge sealing component 4 is also arranged in a surrounding manner using an electric heating plate, and is connected to the equipment body 1 in conjunction with the connecting arm 2 42. After power is turned on, the sealing plate 41 is heated, so that the upper edge sealing piece 22 and the sealing plate 41 meet in the middle to seal the packaging bag, and at the same time, the internal cutting piece 3 cooperates with the cutting groove to cut the sealed part to obtain a single packaged food.
