Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to an automatic plugging machine. Background Art

[0002] After the cover of the packaging box is produced, a sealing plug needs to be inserted into the plug hole of the cover by a plugging machine, and then the cover is sealed on the box body of the packaging box.

[0003] like Figure 1 The cover of the packaging box needs to be continuously switched between round cover and square cover due to the production needs of different batches of products. However, the current plugging machine can usually only adapt to a single-shaped cover structure and cannot be compatible with covers of different shapes at the same time. Once a cover product of a different shape is replaced, it can only be done through the loading mechanism and cover mold of the plugging machine, and the various mechanisms must be re-debugged. The overall operation is relatively inconvenient. Therefore, there is room for improvement. Summary of the Invention

[0012] By adopting the above technical solution, when performing plugging operations on covers of different shapes, the corresponding cover can be placed into the corresponding mold cavity of the conveyor cover mold by the round cover loading mechanism or the square cover loading mechanism according to production requirements. After the conveyor moves the cover mold with the cover to the plugging mechanism, the plugging assembly will load the sealing plug in the sealing plug storage assembly into the cover plug hole on the cover mold to achieve the sealing of the cover plug hole. Compared with the traditional plugging machine, when the cover type changes, the cover plugging operation can be continued by switching different cover loading mechanisms without replacing the cover mold and the loading mechanism, thereby effectively improving the operating efficiency of the plugging machine.

[0024] The driving slider is inserted into the first elongated hole corresponding to the first clamping cover plate and the second elongated hole corresponding to the second clamping cover plate;

[0025] The clamping driving member is used to drive the two driving slide blocks to slide along the front and rear end directions of the round cover storage support.

[0026] By adopting the above technical solution, the two driving sliders are driven to slide by the clamping drive component, which can drive the two first clamping cover plates and the two second clamping cover plates to move alternately relative to each other, thereby realizing the alternating clamping and release of the circular cover plates, so that the circular cover plates in the circular cover storage area can be placed in turn into the circular cover mold cavity corresponding to the conveyor belt cover mold through the cooperation of the first clamping cover part and the second clamping cover part.

[0027] Preferably, the square cover storage assembly comprises a frame, a square cover storage support is supported on the frame, the square cover storage support is provided with a square cover storage area, and the square cover storage area is used for stacking square cover plates;

[0031] The square cover material storage area is provided with a through hole corresponding to the jacking rod, and the through hole is used for the jacking rod to pass through.

[0032] By adopting the above technical solution, after the square cover grabbing part grabs the square cover plate at the top of the square cover storage area, the lifting drive part of the lifting assembly drives the lifting rod to move upward to lift the remaining square cover plates in the square cover storage area upward, which is beneficial for the square cover grabbing part to always grab the square cover plates at a fixed material picking position, and there is no need to adjust the material picking position when grabbing the square cover plates due to the reduction of square cover plate transportation, which is beneficial to improving the material picking efficiency and stability of the square cover grabbing part for the square cover plates.

[0033] Preferably, there are several square cover storage areas on the square cover storage support, and the frame is provided with a sliding drive component corresponding to the square cover storage support, and the sliding drive component is used to drive the square cover storage support to slide in the horizontal direction, so as to drive the several square cover storage areas on the square cover storage support to be alternately located above the jacking assembly.

[0037] By adopting the above technical solution, the rotary drive member is used to drive the plug storage turntable to rotate, so that the plug loading grooves evenly distributed on the outer circumference of the plug storage turntable pass through the plug removal station one by one. When the plug loading groove moves to the plug removal station, the plug loading robot cooperates with the plug grabbing part to grab the sealing plug in the plug loading groove and insert it into the plug hole of the cover plate, thereby completing the packaging of the plug hole of the cover plate.

[0038] Preferably, it also includes a plugging mechanism, which is located downstream of the plugging mechanism.

[0042] 2. Through the arrangement of the first clamping cover part and the second clamping cover part in the round cover placing assembly, the first clamping cover part and the second clamping cover part cooperate to alternately clamp and release the round cover plate, which is conducive to stably placing the round cover plate in the round cover storage area into the corresponding round cover mold cavity on the cover plate mold.

[0067] Reference Figure 6 and Figure 7The round cover storage support 21 is provided with a clamping drive assembly 25 for driving the first clamping cover portion 23 and the second clamping cover portion 24 to alternately clamp and release the round cover. When the clamping drive assembly 25 drives the two first clamping cover plates 231 of the first clamping cover portion 23 toward each other to clamp the round cover, it also drives the two second clamping cover plates 241 of the second clamping cover portion 24 away from each other to release the round cover; when the clamping drive assembly 25 drives the two first clamping cover plates 231 of the first clamping cover portion 23 away from each other to release the round cover, it also drives the two second clamping cover plates 241 of the second clamping cover portion 24 toward each other to clamp the round cover.

[0068] Specifically, the clamping drive assembly 25 includes two drive rods 251, each slidably connected to the bottom of the dome storage support 21.
