High-speed paper cup machine bottom rolling mechanism

Abstract

The invention discloses a high-speed paper cup machine bottom rolling mechanism. A second power connecting rod assembly drives a sliding base to slide along a line rail so as to drive a fort base to move to be close to a cup body mold, and a paper cup body and a cup bottom on the cup body mold correspondingly enter a bottom mold and a knurling mold; then a first power connecting rod assembly pushes a swing rod to rotate around a rotating shaft so as to drive a center shaft to move in the axial direction of the center shaft, a roller on the center shaft moves in an inclined guide groove, then aswing arm is driven to rotate around a pin shaft, a front end stirring head of the swing arm drives a sliding bearing pedestal to move along a guide rail, and therefore the knurling mold is driven tomove along the guide rail so as to be close to the inner wall of the bottom mold to clamp the cup body; and a first driving mechanism drives the knurling mold to rotate so as to achieve rotary knurling operation on the bottom of the cup body. The high-speed paper cup machine bottom rolling mechanism is convenient to machine, few in part and easy to assemble, clamping and releasing of the cup bodybetween the knurling mold and the bottom mold are achieved directly through actions of the swing rod and the swing arm, a spring does not need to be arranged, and the problem of spring failures is avoided.

Description

technical field [0001] The invention relates to the technical field of paper cup forming, in particular to a bottom rolling mechanism of a high-speed paper cup machine. Background technique [0002] In the prior art, during the production process of the paper cup, the cup body and the cup bottom are processed separately, then the cup bottom is loaded from the bottom of the cup body, and then the cup body paper and the cup bottom paper of the paper cup are pressed by the bottom rolling device. To make the finished paper cup, usually the cup bottom and the cup body are set on the paper cup mold, and the joint part of the cup bottom and the cup body is dropped into the knurling mold. The rolling wheel of this knurling mold is on the rolling wheel In the seat, the rolling wheel faces the side of the rolling wheel seat during work, and squeezes the knurled part at the bottom of the paper cup. [0003] The rolling wheel is set on the movable block (that is, the slider), and the t...
