It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.

In some alternative embodiments, as shown in fig. 6, the cover lifting structure includes: a detachable blade structure fixed to the lateral end bracket bar 21 by screws; the blade 28 is fixed in the accommodating groove of the detachable blade structure through a screw, and the blade 28 is used for lifting the coating film layer of the material box 12.

It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.

In a specific example, a rectangular blade bar 23 is provided, the width of the blade bar 23 (i.e. the edge of the blade) is the same as the inner width of the material box 12, and the long edge of the lower bottom of the blade bar 23 is cut and the upper bottom is closed.

In addition, a detachable blade structure is designed, two end cylinders 26 are of a limiting structure, and the two cylinders 26 penetrate through hollow limiting grooves 27 of the left side surface 3 and the right side surface 3 of the food material temporary storage compartment. When the two cylinders 26 are positioned at the lower ends of the limiting grooves 27, the blades 28 just penetrate into a point below the coating film layer of the material box 12. When the rotating motor (driving mechanism) unloads the force, under the action of the inner acute angle spring 22, the two cylinders 26 are located at the upper ends of the limiting grooves 27, so that the blades 28 are located at a point above the coating film layer of the material box 12, and keep a far distance from the gesture.

If the coated blade 28 is to be cleaned, the screw on the removable blade structure is manually unscrewed, then the blade 28 is manually cleaned, and the blade 28 is then mounted back onto the removable blade structure after cleaning. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.

In a specific example, the rotating shaft 19 is connected to a motor, and forward and reverse rotation of the motor drives the rotating shaft 19 to rotate forward and reverse to drive the bracket to descend. The support descends and extrudes the acute angle spring 22 in the forward direction of the rotating shaft 19, so that the blade 28 for opening the coating film layer is gradually close to the coating film layer on the top surface of the material box 12, and is suspended until the lower end of the limiting groove 27 touches the cylinder 26, so that the rectangular blade strip 23 just cuts into the inner coating film layer on the upper top surface of the material box 12, at this time, the lower bottom edge of the rectangular blade strip 23 integrally cuts the inner transverse edge of the coating film layer on the upper top surface of the material box 12, and the triangular angle knife 24 cuts into the inner long edge of the coating film layer on the upper top surface of the material box 12 along the trend. Conversely, note that when the motor is de-energized, the long end support bar 20 of the support is extended under the force of the acute angle spring 22, so that the blade 28 on the transverse end support bar 21 of the support returns to the default condition to remain away from the magazine 12. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.

In one specific example, the motor is rotated forward so that the long end bracket bar 20 of the bracket connected to the rotating shaft 19 presses the inner acute angle spring 22, so that the blade 28 on the transverse end bracket bar 21 of the bracket gradually approaches the coating film layer on the top surface of the material box 12 until the lower end of the limit groove 27 is touched to stop, so that the rectangular blade bar 23 just cuts into the inner coating film layer on the transverse edge of the upper top surface of the material box 12, the lower bottom edge of the rectangular blade bar 23 integrally cuts into the inner transverse edge of the coating film layer on the upper top surface of the material box 12, and the triangular angle knife 24 cuts into the inner long edge of the coating film layer on the upper top surface of the material box 12 along the trend. Then, the bottom conveyor 5 of the temporary storage compartment for food material starts to move, and in the process of transporting the material box 12 out of the temporary storage compartment for food material, the blade 28 for opening the coating film layer lifts the innermost inner transverse edge of the coating film layer of the material box 12 and cuts the two inner long edges by a certain distance, because the whole coating film layer is not completely separated from the top surface of the material box 12 and remains stuck on the top surface, so that the coating film layer falls into the following prefabricated dish cooking equipment in the following stage of dumping the material box 12 and cannot be recovered. Thereafter, the motor is relieved and the long end support bar 20 of the support is spread under the action of the elastic force of the inner acute angle spring 22, so that the blade 28 on the transverse end support bar 21 of the support returns to the default condition and keeps away from the material box 12. It will be appreciated that the above description is exemplary only, and that the present embodiment is not limited in any way.
