Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic cutting control process for the bottom of paper cups, which overcomes the problem that the bottom paper cutter keeps cutting the bottom paper without the paper cup barrel during the production of paper cups by the current medium-speed paper cup machine. The waste of bottom paper makes the paper cup bucket correspond to the bottom paper of the paper cup

Embodiment

[0015] Such as figure 1 As shown, the present invention comprises programmable logic controller PLC, and PLC is connected with cup body detector, bottom paper detector, and receives its signal, and PLC controls paper cutting motor and paper feeding motor according to the signal received, and cup body detector The bottom paper detectors are all photoelectric switches, and there is an indicator light connected to the PLC, which is controlled by the cup body detector.

[0016] Such as figure 2 As shown, the specific working process is as follows: the photoelectric switch of the cup body detector detects whether there is a cup body at the designated position. Whether there is a backing paper at the position, if there is a backing paper, the paper cutting motor is triggered by PLC. The paper cutting motor is a servo motor, and its rotation is easy to control. The servo motor drives the paper cutting circular knife to cut paper once through the drive of the cam, that is, the servo...

Abstract

The invention discloses a paper cup bottom automatic cutting control technology, which comprises a guillotine motor that drives a cutting knife to cut bottom paper, a paper feeding motor that conveys the bottom paper, a bottom paper detector, a cup body detector, and a PLC, wherein an input terminal of the PLC is connected with the bottom paper detector and the cup body detector; the output terminal of the PLC is connected with the guillotine motor and the paper feeding motor; the PLC receives a detection signal from the bottom paper detector and the cup body detector and controls the on-off of the guillotine motor and the paper feeding motor based on the received signal. The guillotine motor operates only when the cup body arrives an assigned position and the bottom paper arrives at an assigned position. In this way, the problem that the bottom paper cutting knife cuts the bottom paper always even no cup body exists is solved, and bottom paper waste and cost are saved. The PLC is used to replace a relay, therefore, advantages like long service life, low noise and ultra high stability are provided.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic cutting control process for the bottom of a paper cup. Background technique [0002] In the process of producing paper cups by the medium-speed paper cup machine, the paper cup bottom paper is cut with a circular knife structure. In the process of cutting the bottom paper, each paper cup bucket is equipped with a paper cup. The knife is driven by the thorn wheel. As long as the main motor is running, it will keep cutting the bottom paper. If there is no cup and bucket coming, it will still be cutting, which will waste the bottom paper. Contents of the invention [0003] The purpose of the present invention is to provide an automatic cutting control process for the bottom of paper cups, which overcomes the problem that the bottom paper cutter keeps cutting the bottom paper without the paper cup barrel during the production of paper cups by the current medium-speed pape...
