[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0036] Example 1

[0037] Reference Figure 1 The carton closing mechanism provided in the present embodiment comprises an opening unit 1, a prop cover unit 2, a first cover closing unit 3 and a second cover closing unit 4. The prop cover unit 2, the first cover closing unit 3 and the second cover closing unit 4 are all located below the opening unit 1, the first cover closing unit 3 and the second cover closing unit 4 are cross arranged, and the second cover closing unit 4 is arranged adjacent to the prop cover unit 2. The prop cover unit 2 is used for proping open the long side covers of the carton, the first cover closing unit 3 is used for closing the short side covers of the carton, and the second cover closing unit 4 is used for closing the long side covers of the carton.

[0038] It can be understood that the carton is in a vertical plate shape when it is delivered, and the cover plate to be closed is located at the lower end of the delivered carton. The carton is opened by the opening unit 1, so that the plate-shaped carton becomes a three-dimensional shape, and then the cover supporting unit 2, the first cover closing unit 3 and the second cover closing unit 4 cooperate to complete the carton closing operation. During the closing operation, the cover supporting unit 2 first opens the two long side covers of the carton outward by about 10° from the vertical state, and then the first cover closing unit 3 closes the two short side covers of the carton, and then the cover supporting unit 2 is reset, and the second cover closing unit 4 closes the two long side covers of the carton, and the closing operation is completed. It should be noted that after the first cover closing unit 3 closes the two short side covers of the carton, it is not reset immediately, but waits for the second cover closing unit 4 to close the two long side covers of the carton to a certain angle, and then the first cover closing unit 3 is reset, so that the short side covers and the long side covers of the carton can be completely closed.

[0039] The carton closing mechanism of the embodiment ensures that the two long side covers of the carton are in an open state during the operation of closing the two short side covers of the carton, avoids interference of the two long side covers of the carton with the operation of closing the two short side covers of the carton, ensures normal and orderly operation of the closing operation, improves production operation efficiency and operation quality, and improves operation qualification rate.

[0042] In some embodiments, the first driving part 412 and the second driving part 422 can be driving cylinders or driving motors. The first driving part 412 and the second driving part 422 are driven simultaneously, and during the driving process, the first cover closing part 411 and the second cover closing part 421 move upwardly and obliquely in a direction close to each other, push the outer side of the two long side covers of the carton, and close the two long side covers of the carton. The cooperation of the first cover closing assembly 41 and the second cover closing assembly 42 can realize the simultaneous closing of the two long side covers of the carton, which is beneficial to improve the operation efficiency.

[0043] The supporting lid unit 2 comprises a first supporting lid assembly 21 and a second supporting lid assembly 22 which are symmetrically arranged, the first supporting lid assembly 21 corresponds to the position of the first lid assembly 41, and the second supporting lid assembly 22 corresponds to the position of the second lid assembly 42.

The carton feeding bin 5 is provided with a pushing assembly 51 and a limiting assembly 52, the pushing assembly 51 is used for pushing the carton to be opened in a horizontal direction to abut against the limiting assembly 52, so that a plurality of cartons to be opened are in a vertical state and are closely arranged in the carton feeding bin 5.

[0048] As one of the implementations, the pushing assembly 51 comprises a pushing plate and a stepping motor for driving the pushing plate to move horizontally, when the suction assembly 11 takes away a carton from the carton feeding bin 5, the stepping motor drives the pushing plate to move forward by one step, so that the pushing plate pushes the carton to abut against the limiting assembly 52 again.

[0049] The first lid closing unit 3 comprises a third lid closing assembly 31 and a fourth lid closing assembly 32 which are symmetrically arranged, the third lid closing assembly 31 comprises a third lid closing component 311 and a fifth driving member 312 for driving the third lid closing component 311 to rotate upward, and the fourth lid closing assembly 32 comprises a fourth lid closing component 321 and a sixth driving member 322 for driving the fourth lid closing component 321 to rotate upward.

[0050] In some implementations, the fifth driving member 312 and the sixth driving member 322 can be driving motors or driving cylinders. The fifth driving member 312 and the sixth driving member 322 are simultaneously driven to rotate the third lid closing component 311 and the fourth lid closing component 321 upward in the direction of approaching each other, so as to push the short side lids on both sides of the carton to be closed simultaneously. The simultaneous closing of the short side lids on both sides of the carton can be realized through the cooperation of the third lid closing assembly 31 and the fourth lid closing assembly 32, and the production efficiency can be further improved.
