Description

Technical Field

[0001] The utility model relates to the technical field of unwinding equipment, in particular to an unwinding pre-driven swing device for a paper splicer. Background Art

[0002] During the production process of a paper splicer, a reeling mechanism is usually required to reel out the base paper roll. The existing reeling mechanism of the base paper roll usually clamps the base paper roll on a reel. During production, the paper splicer automatically pulls the base paper through the traction function of the splicer's original belt, causing the base paper roll to rotate and unwind.

[0003] However, since the base paper rolls used in actual production are heavy, if the base paper is only actively pulled by the splicer, it is easy to break when the splicer runs at high speed, which causes the running speed of the splicer to be reduced to adapt to the unwinding speed. Utility Model Content

[0006] In the above-mentioned unwinding pre-driven swing device for a paper splicer, the push plate unit includes a mounting plate, which is fixedly arranged in the rocker arm, and a push cylinder located inside the rocker arm is installed on one side of the mounting plate. The cylinder shaft of the push cylinder passes through the mounting plate, and the cylinder shaft of the push cylinder is connected to a push plate, and the push plate is located on the outside of the rocker arm.

[0007] In the above-mentioned unwinding pre-driven swing device for a paper splicer, a plurality of guide rods are provided on the mounting plate, and one end of the guide rod is connected to the push plate.

[0008] The above-mentioned unwinding pre-driven rocking device for a paper splicer also includes an unwinding frame, on which a rotatable rocker shaft is installed. The end of the rocker away from the rotating shaft is connected to the rocker shaft. Two rockers are provided, and the two rockers are symmetrical on the left and right.

[0010] In the above-mentioned unwinding pre-driven rocking device for a paper splicer, two rocker arm shafts are provided.

[0011] The beneficial effects of the utility model are as follows: the internal expansion type chuck is extended into the roll material to tighten it, and then the internal expansion type chuck is driven by the servo motor to rotate, thereby causing the roll material to rotate, thereby adapting to the traction speed of the paper splicer itself, preventing the phenomenon of base paper breaking due to active traction of the roll material, and greatly improving the paper splicing speed and efficiency; at the same time, the push plate unit can push the roll material down in a telescopic manner to facilitate unloading.
