[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figure 1 As shown, a pushing mechanism for food packaging includes a first conveyor belt 1 for conveying packaging boxes, a second conveyor belt 2 for conveying food, and a transition plate 3 arranged between the first conveyor belt 1 and the second conveyor belt 2. Food and packaging boxes are conveyed from right to left on the conveyor belt. A pushing frame 4 for pushing food is provided on the bracket of the second conveyor belt 2. The pushing frame 4 includes a vertical plate in contact with food in the vertical direction arranged at the rear end and a horizontal plate arranged at the upper end of the vertical plate. A supporting plate 5 for propping up the cover plate of the packaging box is symmetrically provided on the transition plate 3. When the first conveyor belt 1 conveys the packaging box to the position of the transition plate 3, the supporting plate 5 supports the cover plate of the packaging box, and the pushing frame 4 moves backward to push the food into the packaging box. There is no need to manually hold the food into the packaging box to prevent food contamination.

[0023] like Figure 1 As shown, the first conveyor belt 1 and the second conveyor belt 2 are arranged in parallel front and back.

[0024] like Figure 2 As shown, a guide sleeve 8 is provided on the bracket of the second conveyor belt 2, and a guide rod 9 cooperating with the guide sleeve 8 is provided in the pushing frame 4. Under the guiding action of the guide sleeve 8 and the guide rod 9, the pushing frame 4 continuously moves forward and backward.

[0025] like Figure 1 As shown, a driving mechanism for driving the pushing frame 4 to reciprocate is provided on the bracket of the second conveyor belt 2. The driving mechanism includes a turntable 6 and a connecting rod 7 provided on the bracket of the second conveyor belt 2, the front end of the connecting rod 7 is rotatably connected to the eccentric position of the turntable 6, and the rear end of the connecting rod 7 is rotatably connected to the front end of the pushing frame 4. When the turntable 6 rotates, under the action of the connecting rod 7, the pushing frame 4 continuously moves forward and backward, and pushes the food into the packaging box in sequence.

[0026] like Figure 2 As shown, a mounting frame 10 is provided on the bracket of the second conveyor belt 2, the turntable 6 is fixed on the mounting frame 10, and a motor for driving the turntable 6 to rotate is provided on the mounting frame 10.

[0027] like Figure 1As shown, the front end of the support plate 5 on the left is rotatably connected to the transition plate 3, and the support plate 5 on the right is fixed on the transition plate 3. When the push frame 4 moves forward and backward, the support plate 5 on the left swings left and right under the action of the linkage mechanism. When the packaging box moves to the transition plate position, the cover plate at the left end contacts the support plate 5 on the left after passing the support plate 5 on the right. When the push frame 4 moves backward, under the action of the linkage mechanism, the support plate 5 on the left swings right quickly and resets, so that the support plate 5 on the left can open the cover plate on the left, and the support plate 5 on the right can open the cover plate on the right. This prevents the cover plate from blocking the food when the food is pushed into the packaging box.

[0028] like Figure 1 As shown, the linkage mechanism includes a swing rod 11 disposed at the upper end of the rotating shaft of the support plate 5 on the left side, and a guide hole 12 disposed on the pushing frame 4. The guide hole 12 is provided with a protrusion 13 protruding to the left, and the front end of the swing rod 11 is provided with a guide rod matched with the guide hole 12. When the pushing frame 4 moves backward, the guide rod moves in the guide hole 12. When the guide rod cooperates with the protrusion 13, the support plate 5 on the left side can swing to the right under the action of the swing rod 11. The swing of the left support plate 5 is realized through the mechanical structure, and no separate driving mechanism is required, which is low in cost.
