In an embodiment of the present invention, as shown in fig. 1 to 8, the cassette bottom molding machine includes:

a housing 30, said housing 30 having a worktop 31;

the folding mechanism comprises a turntable assembly 41, a sleeve die 42 and a plurality of folding modules, wherein the turntable assembly 41 is rotatably mounted on the worktable surface 31, the sleeve die 42 is mounted on the turntable assembly 41 and is used for sleeving the lining box 20, the sleeve die 42 can rotate along with the turntable assembly 41 to form a plurality of folding positions, and each folding module is mounted corresponding to each folding position; the plurality of folding positions comprise box positions;

the lining feeding mechanism is arranged on the working table surface 31 and is arranged corresponding to the sleeve box position; the lining box 20 feeding mechanism comprises a transferring module 51 and a material transferring arm 52 arranged on the transferring module 51; the material transferring arm 52 is used for sucking the lining box 20, and the transferring module 51 is used for driving the material transferring arm 52 to move so as to transfer the lining box 20 from a loading position to the sleeve mold 42.

In this embodiment, the frame 30 is used for mounting the functional components of the carton bottom forming machine, the functional components are usually mounted on a table 31 of the frame 30, and form a folding line on the table 31, and the cardboard entering the folding line is folded into a carton bottom 10 with one open end.

The folding mechanism is used to fold the cardboard into the carton bottom 10, and the specific form of the folding mechanism is not limited. Specifically, before the cardboard enters the folding mechanism, the lining box 20 is firstly sleeved on the sleeve mold 42, after the lining box 20 is sleeved on the sleeve mold 42, the rotary table assembly 41 rotates the sleeve mold 42 to the initial feeding position of the cardboard, then other folding mechanisms can wrap and fold the cardboard around the lining box 20, and the finally formed box bottom finished product is a double-layer box body with an opening at one end.

The specific structure of the material conveying arm 52 is not limited, and only the requirement that the lining case 20 can be sucked from the top of the lining case 20 is satisfied. The lining box 20 has a material loading position on the working platform 31, and after the lining box 20 is sucked by the material transferring arm 52, the transferring module 51 drives the material transferring arm 52 to move so as to transfer the lining box 20 to be sleeved on the sleeve mold 42, thereby realizing the automatic sleeve of the lining box 20 on the sleeve mold 42. Compared with the method that the lining box 20 is sleeved on the sleeve die 42 manually, the lining box 20 is moved through the lining feeding mechanism, the feeding time of the lining box 20 can be shortened, the feeding efficiency of the lining box 20 is improved, and the overall production efficiency of the box bottom forming machine is improved.

The box bottom forming machine is characterized in that a lining feeding mechanism corresponding to a sleeve box position is arranged on a working table surface 31, a lining box 20 is sucked by a material conveying arm 52, and the material conveying arm 52 is driven by a transferring module 51, so that the transferring module 51 and the material conveying arm 52 can transfer the lining box 20 from a feeding position to the sleeve box 42; therefore, the sleeve die 42 can be automatically sleeved on the lining box 20 in the feeding process, so that the feeding efficiency of the lining box 20 can be improved, and the overall production efficiency of the box bottom forming machine can be improved.

By providing the first lifting cylinder and the second lifting cylinder, two lifting strokes can be provided between the material conveying arm 52 and the transfer module 51. When the material conveying arm 52 needs to suck the lining box 20 from the loading position, the lining box descends by two strokes; after the lining box 20 is sucked, the lining box is lifted for a stroke, and the opening of the lining box 20 is aligned with the sleeve die 42; the transfer module 51 drives the material conveying arm 52 to approach the sleeve mold 42, so that the liner box 20 is sleeved on the sleeve mold 42. After the liner box 20 is completely installed, the transfer arm 52 is raised a further stroke and moved away from the sleeve mold 42.

When the lining box 20 is sucked by the material transfer arm 52 and sleeved on the sleeve die 42, an interval is formed between the lining box 20 and the supporting surface of the material loading position, so that the lining box 20 is prevented from being rubbed; after the lining box 20 is sleeved on the sleeve mold 42, the material transfer arm 52 is lifted for a stroke to form a space with the lining box 20, so that the material transfer arm 52 is prevented from rubbing the lining box 20. Therefore, in the process of sleeving the lining box 20 on the sleeve die 42, the lining box 20 can be prevented from being rubbed by other structures, so that the protection effect on the lining box 20 can be improved, and the yield of the final finished product can be improved.

In one embodiment, as shown in fig. 3, the liner feeding mechanism further includes a conveying platform 100 mounted on the working platform 31, the conveying platform 100 is located below the material conveying arm 52, the extending direction of the conveying platform 100 is the same as the moving direction of the material conveying arm 52, and the conveying end of the conveying platform 100 is adjacent to the sleeve mold 42 to form the feeding position.

The bottom molding machine may further comprise a controller, and the position sensor 70 and the driving device of the stopper 60 are electrically connected with the controller, so that the position sensor 70 and the stopper 60 can realize feedback linkage through the controller. If position sensor 70 detects that liner 20 is not in the fill position, the controller will control stop 60 to exit the stop, thereby allowing liner 20 to continue to the fill position at the ready position; if the position sensor 70 detects that the liner box 20 is loaded, the controller will control the stopper 60 to enter a stop position to stop the other liner boxes 20. The position sensor 70 is coupled with the stopper 60 to control the movement timing of the stopper 60, so that the movement timing of the stopper 60 can be more accurate, and the feeding stability of the liner box 20 can be improved.
