Technical Field

[0001] The utility model relates to paper box forming equipment, in particular to an upper side forming mechanism when a box body is enclosed. Background Art

[0002] In the process of forming a paper box, the paperboard with face paper can be enclosed. The paperboard is pre-grooved, and the paperboard is folded along the grooved position and enclosed on the forming mold to form a frame-shaped paper box body (or surrounding frame, etc.). For example, the CN117754917A box body forming and pasting mechanism, the CN204640911U paper box forming machine upper side forming mechanism, etc., the forming mold is in a horizontal state, wherein the upper folding paperboard component first folds the corresponding paperboard on the upper side of the box body to the upper side of the forming mold, and then the upper face paper component sticks the corresponding face paper on the outside of the paperboard.

[0003] In the paper box forming equipment, in order to adapt to the forming of paper boxes of different specifications and sizes, it is necessary to replace or adjust the forming molds of different specifications and sizes, and the corresponding upper folding paper board components and upper veneer paper components used for forming with the forming molds need to be adjusted. At present, such adjustment and change of the upper side forming mechanism is relatively troublesome, especially when the size deviation of the forming mold is large (for example, the maximum size is larger than the minimum size), the adjustment is not only troublesome, but also requires the replacement of many accessories, and the size deviation is easy to cause unstable forming after adjustment.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the implementation manner of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Referring to the accompanying drawings, in the embodiment of this implementation manner, the upper side forming mechanism of the carton forming device includes an upper side forming device located above the forming die 1. Among them, the upper side forming device includes an upper folding cardboard component 21 and an upper pasting paper component 22. The upper folding cardboard component 21 is used for folding cardboard, and the upper pasting paper component 22 is used for pasting paper, which cooperate with the formation of the upper side of the carton. This is a mature technology and will not be elaborated here.

[0026] In this embodiment, the upper side forming device further includes a lifting bracket 20 located on the frame 3. The lifting bracket 20 will perform lifting actions on the frame 3. The lifting bracket 20 is drivingly connected to a bracket lifting drive motor 23 for lifting adjustment and lifting operation. The bracket lifting drive motor 23 can not only drive the lifting bracket 20 for lifting adjustment to adjust the height position of the lifting bracket 20 during lifting operation (i.e., the upper stop position and the lower stop position), but also drive the lifting bracket 20 to lift and move between these height positions by the bracket lifting drive motor 23 (i.e., the lifting movement during the forming process). A folding plate transverse movement frame 25 and a sticker transverse movement frame 26 are provided on the lifting bracket 20. Transverse guide rails 24 are provided between the folding plate transverse movement frame 25 and the sticker transverse movement frame 26 and the lifting bracket 20. The folding plate transverse movement frame 25 and the sticker transverse movement frame 26 can not only perform lifting actions (including lifting adjustment and lifting operation) together with the lifting bracket 20, but also the folding plate transverse movement frame 25 can move transversely along the transverse guide rails 24 on the lifting bracket 20, and the sticker transverse movement frame 26 can move transversely along the transverse guide rails 24 on the lifting bracket 20.

[0027] The upper folding cardboard component 21 is connected to the folding plate transverse movement frame 25 through a lifting floating drive structure 29. The upper folding cardboard component 21 can not only act together with the folding plate transverse movement frame 25 (including transverse movement and lifting), but also the upper folding cardboard component 21 can additionally lift and float on the folding plate transverse movement frame 25 to cooperate with the forming. The lifting floating drive structure 29 cooperates to drive the upper folding cardboard component 21 to additionally lift and float on the folding plate transverse movement frame 25. The folding plate transverse movement frame 25 is drivingly connected to a folding plate transverse movement drive device 27, and the folding plate transverse movement drive device 27 drives the folding plate transverse movement frame 25 to perform transverse movement to cooperate with the folding cardboard.

[0028] The upper sticker component 22 is arranged on the sticker transverse movement frame 26. The upper sticker component 22 acts together with the sticker transverse movement frame 26 (including transverse movement and lifting). The sticker transverse movement frame 26 is drivingly connected to a sticker transverse movement drive device 28, and the sticker transverse movement drive device 28 drives the sticker transverse movement frame 26 to perform transverse movement to cooperate with the sticking of the sticker.

[0029] The working principle is that when the specifications (such as height) of the forming mold 1 change, the lifting bracket 20 can be driven by the bracket lifting drive motor 23 to lift and adjust the position to adapt to the forming mold 1 with the changed specifications. No additional adjustment operations are required. The folding plate transverse moving frame 25, the upper folding paperboard component 21, the sticker transverse moving frame 26 and the upper pasting paper component 22 on the lifting bracket 20 can all be lifted and adjusted together. After the lifting and adjusting are completed, the upper side of the paper box can be formed; when the upper side is formed, the lifting bracket 20 moves downward to a low position (i.e., the lower stop position). During the movement to the low position, the upper folding paperboard component 21 can move laterally (towards the middle direction) with the folding plate transverse moving frame 25 to cooperate with the folding of the paperboard on the upper side, and the upper folding paperboard component 21 is on the folding plate transverse moving frame 25. The lifting and floating driving structure 29 can be driven to float down and put it in the folding plate working state. After completing the folding paper board work on the upper side, the upper folding paper board component 21 can be driven by the lifting and floating driving structure 29 to float up and separate from the paper board on the lower forming mold 1, so that the upper folding paper board component 21 can be moved back and forth horizontally to make way, so as to avoid the upper folding paper board component 21 and the folded paper board from rubbing against each other and affecting the operation and the product; in addition, after the upper folding paper board component 21 is moved back and forth horizontally to make way, the upper pasting paper component 22 that has been moved to a low position with the lifting bracket 20 can be moved horizontally (towards the middle direction) with the sticker transverse moving frame 26 to cooperate with the pasting of the paper on the side. After completing the pasting paper work on the upper side, the sticker transverse moving frame 26 can be moved back and forth horizontally, and the lifting bracket 20 can be raised and retreated, waiting for the next work.

[0030] The upper side forming mechanism of the paper box forming equipment can adapt to the forming mold 1 by lifting and adjusting the lifting bracket 20 after the specifications of the forming mold 1 change, without additional excessive adjustment operations, and is easy to adjust to adapt to the forming of paper boxes of different specifications and sizes. The entire mechanism almost does not require additional adjustment and has good operating stability. During the forming operation, the lifting bracket 20 is completed through lifting operation, additional lifting and floating of the upper folding paper board component 21, and lateral movement (lateral movement) of the folding plate transverse movement frame 25 and the sticker transverse movement frame 26.

The bracket lifting drive motor 23 can adopt a servo motor with relatively high precision. The bracket lifting drive motor 23 is connected to the lifting bracket 20 through a screw nut transmission mechanism 32, which is convenient for lifting adjustment and lifting operation.

[0033] In addition, the support lifting drive motor 23 can be installed on the frame 3. The lead screw and nut transmission mechanism 32 includes a vertical lead screw 321. The vertical lead screw 321 is connected to the frame 3 by a lead screw rotating support frame 322. At least two vertical lead screws 321 are provided. The vertical lead screws 321 are equipped with transmission nuts 323. The transmission nuts 323 are connected to the lifting support 20. The vertical lead screws 321 and the transmission nuts 323 are in transmission cooperation to drive the support to lift and perform a lifting action. Transmission wheels 324 are respectively provided on the vertical lead screws 321. The transmission wheels 324 are connected to each other by a transmission belt 325. The transmission belt 325 is in transmission connection with the support lifting drive motor 23. The support lifting drive motor 23 drives multiple vertical lead screws 321 to rotate together through the transmission belt 325 and the transmission wheels 324, making the operation more stable and balanced.

[0034] Among them, the lifting floating drive structure 29 includes a lifting drive cylinder, and the transmission connection is relatively convenient. Of course, other ways of driving additional floating lifting can also be adopted.

Among them, the folding plate transverse movement drive device 27 also includes a folding plate transverse movement belt transmission mechanism 272 (including a belt and belt wheels, etc.). The folding plate transverse movement drive motor 271 is in transmission connection with the folding plate transverse movement frame 25 through the folding plate transverse movement belt transmission mechanism 272. Among them, the folding plate transverse movement drive motor 271 can adopt a servo motor.

[0036] For example, the sticker transverse movement drive device 28 includes a sticker transverse movement drive motor 281, which drives the transverse movement operation. Among them, the sticker transverse movement drive device 28 also includes a sticker transverse movement belt transmission mechanism 282 (including a belt and belt wheels, etc.). The sticker transverse movement drive motor 281 is in transmission connection with the sticker transverse movement frame 26 through the sticker transverse movement belt transmission mechanism 282. Among them, the sticker transverse movement drive motor 281 can adopt a servo motor.

[0037] In addition, the upper sticker component 22 and the upper folding cardboard component 21 are respectively arranged on the left and right sides above the forming die 1; the upper folding cardboard component 21 moves horizontally left and right and cooperates with the lifting operation to fold and form the cardboard on the upper side of the semi-finished paper box on the forming die 1; the upper sticker component 22 moves horizontally left and right and cooperates with the lifting operation to stick the sticker on the upper side of the semi-finished paper box on the forming die 1; the upper folding cardboard component 21 and the upper sticker component 22 cooperate with each other to finally complete the forming of the upper side of the paper box. Among them, the upper folding cardboard component 21 adopts a folding pressing plate, and the upper sticker component 22 adopts a roller (such as a brush roller or a rubber roller or other rollers) or a brush strip. In addition, the forming die 1 rotates horizontally around a vertical axis so as to be switched and moved to different stations, and the operation of forming the upper side of the paper box can be carried out at the station in the illustrated position.
