Description

Technical Field

[0001] The invention relates to the technical field of tube die cutting, and in particular to a label tube die cutting device. Background Art

[0002] Some labels need to go through a slitting machine during the production process, and be rolled up on the specified label tube core to form a finished paper roll with certain specifications and certain tightness requirements before leaving the factory. Due to the different sizes of labels, the label tube core needs to be cut before the label is rolled up so that the tube core can meet the label rolling requirements.

[0003] In order to prevent the label tube core from deforming during cutting, the existing cutting process is to put the label tube core on a mandrel before cutting, and the mandrel is used to support the label tube core, which can effectively prevent the label tube core from deforming. However, this cutting process is inefficient and takes a lot of time to remove the cut label tube core, which needs to be improved. Summary of the invention

[0005] The label tube core cutting device includes a base, and a first linear drive mechanism and a second linear drive mechanism are horizontally installed at both ends of the base, which are perpendicular to each other. The moving end of the first linear drive mechanism is connected to a carrier platform, and two movable blocks are slidably installed on the carrier platform along the moving direction of the carrier platform. An adjustment mechanism that can fix the two movable blocks and adjust the distance between the two movable blocks is installed on the carrier platform. An automatic chuck and a motor that drives the automatic chuck to rotate are connected to the moving end of the second linear drive mechanism, and the axial direction of the automatic chuck is parallel to its own moving direction. The upper part of the base is parallel to the movable Two core shafts are horizontally arranged at a position between the block and the automatic chuck, the core shafts are parallel to the axial direction of the automatic chuck, one end of the axial direction of the two core shafts is detachably connected to two movable blocks, and an axis head is coaxially arranged at one end of the core shaft away from the movable block, a ring is rotatably mounted on the axis head, the outer diameter of the ring is the same as the outer diameter of the core shaft, and the automatic chuck can clamp any of the rings, a manipulator is installed on the base, and a cutting machine is installed on the manipulator, and the cutting machine can cut the label tube core mounted on the core shaft and clamped by the automatic chuck.

[0006] Furthermore, the adjustment mechanism includes a double-headed screw and two screw seats, the double-headed screw is fixed to the bearing platform through the two screw seats, and the two movable blocks are respectively threadedly connected to the two threaded sections of the double-headed screw.

[0007] Furthermore, a special-shaped socket is formed on the end face of the movable block close to the automatic chuck, and a special-shaped shaft is coaxially connected to the end of the core shaft away from the shaft head. The special-shaped shaft is inserted into the special-shaped socket and fixed in the special-shaped socket by a bolt pin.

[0008] Another object of the present invention is to provide a label die cutting process, the process steps are:

[0009] S1: a label tube core is placed on one of the core shafts;

[0010] S2: Move the carrier to align the mandrel with the uncut label tube core with the automatic chuck;

[0011] S3: Move the automatic chuck to press against the label tube core, the automatic chuck clamps the label tube core together with the ring, turn on the motor to rotate the label tube core, and move the cutting machine through the robot to cut the label tube core;

[0012] S4: During slitting, another label tube core is put on another mandrel;

[0013] S5: After the slitting is completed, release the automatic chuck, move the automatic chuck away from the label tube core, move the carrier, remove the cut label tube core, and repeat S2 to S4.

[0014] The beneficial effects of the present invention are as follows: by setting two core shafts, when one core shaft is used for cutting, the label tube core can be disassembled and assembled on the other core shaft, which effectively utilizes time. Compared with the conventional label tube core cutting machine, the waiting time for tube loading and removal can be saved; the core shaft and the movable block are detachably connected, which is convenient for replacing the core shaft, and the distance between the two movable blocks can be adjusted according to the size of different core shafts to ensure the safety of tube loading and removal.
