[0057] In actual use, when the oil enters the through groove 1221, the oil pushes the inflatable ball 25 to move away from the oil delivery cavity two 1213, so that a space is left between the inflatable ball 25 and the inner wall of the through groove 1221 for the oil to pass through, at this time, the sliding bar 24 located outside the extension pipe 122 is pulled into the through groove 1221, so that the length of the sliding bar 24 located outside the extension pipe 122 is reduced, when the oil does not enter the through groove 1221, the sliding bar 24 is pulled to extend out of the extension pipe 122 under the action of the gravity of the fixed block 26, to block the through groove 1221 with the inflatable ball 25 and abut against the inner wall of the through groove 1221, at this time, the length of the sliding bar 24 located outside the extension pipe 122 is increased, and the length of the part of the sliding bar 24 located outside the extension pipe 122 can be observed to determine the oil flow condition in the through groove 1221.

[0058] Referring to Figure 8 and Figure 9 , the inner side wall of the through hole 1214 is provided with a giving slot 1215, the block 121 is hingedly connected with a rotating rod 27, the rotating rod 27 is located in the giving slot 1215, and the hinging shaft of the rotating rod 27 is located at the lower end of the giving slot 1215, the hinging axis of the rotating rod 27 is horizontally arranged, the hinging shaft of the rotating rod 27 is fixed with an elastic member three 271, the elastic member three 271 abuts against the block 121, so that the rotating rod 27 has a tendency to turn close to the through groove 1221, and the elastic force of the elastic member three 271 is smaller than the elastic force of the elastic member one 142, in the embodiment, the elastic member three 271 is a torsion spring.

[0059] Referring to Figure 9 , the rotating rod 27 is fixed with an elastic column 28, the elastic column 28 is fixed to one side of the rotating rod 27 away from the bottom of the giving slot 1215 and is perpendicular to the rotating rod 27, and the elastic column 28 is used for clamping into the through groove 1221, in the embodiment, the material of the elastic column 28 is rubber.

[0060] In actual use, when it is observed that the length of the part of the sliding bar 24 outside the extension pipe 122 is large and it is judged that the oil liquid does not enter the through groove 1221, the sliding part 1021 can be moved upward, the block 121 is driven to move upward by the elastic force of the elastic member two 17 through the reset of the sliding part 1021, the block 121 drives the rotating rod 27 to move upward, until the rotating rod 27 and the extension pipe 122 are staggered, the rotating rod 27 is turned to be close to the extension pipe 122 under the action of the elastic member three 271, the elastic column 28 is clamped into the through groove 1221 to break the oil film, so that the oil liquid enters the through groove 1221.

[0061] Then the sliding part 1021 is loosened, the sliding part 1021 is reset to move downward under the action of the elastic member two 17, the block 121 is driven to move downward, the extension pipe 122 abuts against the rotating rod 27 to push the rotating rod 27 to turn away from the extension pipe 122, and then the extension pipe 122 abuts against the elastic column 28 to make the elastic column 28 deform to abut against the surface of the extension pipe 122.

[0062] The implementation principle of the long-service-life discharging rack for take-out box production in the embodiment of the application is as follows:

[0063] During the working process of the discharging rack, the block 121 is driven to reciprocate by the driving assembly 14, when the block 121 slides away from the oil conveying cavity one 13, the air pressure in the oil conveying cavity one 13 becomes small, so that the oil liquid in the oil storage cavity 1011 is sucked into the oil conveying cavity one 13 through the one-way valve one 11, when the block 121 slides close to the oil conveying cavity one 13, the air pressure in the oil conveying cavity one 13 becomes large, the air pressure drives the oil liquid in the oil conveying cavity one 13 to enter the oil conveying cavity two 1213 through the one-way valve two 23, and then flows into the movable cavity 51, lubricates the rotating shaft 6 in the movable cavity 51, reduces the friction between the rotating shaft 6 and the mounting seat 5, so that the abrasion between the rotating shaft 6 and the mounting seat 5 during the working process of the discharging rack can be reduced, and the service life of the rotating shaft 6 and the mounting seat 5 can be prolonged.

[0064] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
