[0002] After the shell of the air conditioner is produced through the injection molding process, there are usually some material heads left on the surface of the shell. In order to ensure the smoothness of the surface of the air conditioner shell, the material heads need to be cut off. First, use a cutter to cut off the material heads, and then use a polishing roller to grind and polish the cut-off position to make the cut-off position smooth and flat.

[0003] After searching, the patent with publication number CN219360183U discloses a material head cutting device for the production of air-conditioning injection molding parts, including a supporting mechanism, a cutting mechanism and a polishing mechanism.

The movable connecting plate is arranged inside the supporting mechanism, and four sliding support shafts are arranged inside the movable connecting plate. The gear box is arranged at the front of the movable connecting plate. The first driving motor is used to drive the main shaft to rotate, so that the tool rotates, the screw rod is used to rotate to drive the movable connecting plate to move, and the second driving motor is used to drive the pulley to rotate, so that the pulley drives the transmission belt to rotate, thereby rotating the rotating shaft and the polishing wheel, which can improve the cutting efficiency and improve the cutting quality.

[0004] In the process of cutting off the material head in the above-mentioned patent, the tool is first moved to the appropriate position by rotating the screw rod through the crank, and then the operator holds the air-conditioning casing and inserts the excess material head into the special-shaped hole of the protective cover, and starts the first drive motor to drive the tool to cut off the material head.

The remaining material heads are continuously repeated with the above steps to achieve the cutting process. The whole cutting process is cumbersome to operate, which makes it inconvenient to cut off the material head on the air-conditioning casing. Therefore, the present application provides a material head cutting device for the production of air-conditioning injection molding parts to meet the needs. Utility Model Content

Move the air-conditioning shell so that multiple material heads pass between the two cutters 21 in turn. The motor 1 22 drives the cutter 21 to rotate to achieve the removal of multiple material heads. After removal, continue to push the air-conditioning shell to move so that the removal position of the material head passes through the polishing roller 25. The motor 26 drives the polishing roller 25 to rotate to achieve polishing of the removal position. After polishing is completed, the removal and polishing of the material head on the air-conditioning shell are achieved. In order to prevent the material head on the air-conditioning shell from wearing the same position on the surface of the polishing roller 25 for a long time, the cylinder 31 can be started, and the piston rod of the cylinder 31 can be extended or shortened. When extended, the polishing roller 25 can be driven to rotate. The round box 371 drives the connecting shaft 34 to move to the right, and the connecting shaft 34 drives the connecting strip 35 to move to the right along the inner wall of the slide groove 36 on the rotating drum 33, so that the polishing roller 25 moves to the right along the surface of the rotating drum 33, and the position of the polishing roller 25 on the rotating drum 33 is changed. When the piston rod of the cylinder 31 is shortened, the connecting shaft 34 is driven to move to the left by the round box 371, and the connecting shaft 34 drives the connecting strip 35 to move to the left along the inner wall of the slide groove 36 on the rotating drum 33, so that the polishing roller 25 moves to the left along the surface of the rotating drum 33, and the position of the polishing roller 25 on the rotating drum 33 is changed. By changing the position of the polishing roller 25, the material head cutting position is prevented from wearing the same position of the polishing roller 25 for a long time, so that the surface of the polishing roller 25 is evenly worn, thereby improving the service life of the polishing roller 25.
