Technical Field

The utility model relates to a paper feed part of paper handkerchief cutting equipment especially relates to a paper feeding mechanism of anti-sticking paper handkerchief cutting machine.

Background

The traditional tissue box is a hand-pulling paper tape type box body with a built-in roll paper shaft and a paper outlet arranged at the front end, and a user needs to pull out and tear the tissue when taking the tissue, so that the tissue box is troublesome to use and is not sanitary. In order to overcome the defects of the traditional tissue box, an intelligent tissue machine is available in the market, which can realize automatic paper feeding, paper cutting and paper discharging of tissues or towels and is also called a tissue cutting machine.

Chinese patent CN102429606A discloses an intelligent tissue dispenser, which comprises a housing, a paper feeding mechanism, a paper cutting mechanism located below the paper feeding mechanism, and a control circuit, wherein the paper feeding mechanism comprises a transmission shaft and a driven shaft closely fitted with the side surface of the transmission shaft, the transmission shaft is driven by a paper discharging motor, and the transmission shaft and the driven shaft are transversely fixed at two ends respectively through tension springs; the paper cutting mechanism comprises a movable cutter, a stationary cutter, a cutter frame and a driving shaft, wherein the movable cutter is arranged above the cutter frame, a plurality of spring holes are longitudinally formed in the front end of the cutter frame, springs are arranged in the spring holes and matched with the front end of the movable cutter, and the rear end of the movable cutter is fixed on the cutter frame; the rear end of the tool rest is fixedly connected with more than one rack, a gear matched with the rack is arranged on the driving shaft, and the driving shaft is driven by the movable knife driving motor. The paper outlet mechanism of the patent comprises two paper outlet roller shafts which are oppositely arranged, and the paper outlet roller shafts are in transmission connection with a paper outlet motor. The paper feeding mechanism or paper feeding mechanism of the existing paper towel cutting machine mainly comprises a front roll shaft and a rear roll shaft, the two roll shafts are arranged on an integrated shaft frame, and the end parts of the two roll shafts are connected through a spring. When the paper towel rolling machine works, paper towels enter between the two roll shafts and move downwards by virtue of friction force between the paper towels and the roll shafts. Because can produce the wastepaper among the paper handkerchief cutting process, and the wastepaper adsorbs on the roller easily because of reasons such as static, causes the card paper. In addition, the roller shaft can generate static electricity in the rotating process, and paper towels are easily adsorbed on the roller shaft due to the static electricity, so that paper jam is caused.

Aiming at the defects of a paper feeding mechanism of a traditional paper towel cutting machine, chinese patent CN108275494A discloses a paper feeding mechanism of a paper towel cutting machine, wherein the paper feeding mechanism comprises a front shaft frame, a rear shaft frame, a front roller shaft mounting plate, a rear roller shaft and a rear roller shaft mounting plate, the front roller shaft and the rear roller shaft are arranged in parallel in the front and at the back, a plurality of rollers are respectively arranged on the front roller shaft and the rear roller shaft at intervals, and the rollers of the front roller shaft and the rollers of the rear roller shaft are in one-to-one correspondence and are arranged in a close fit manner in the front and at the back; the front shaft bracket comprises a front shaft bracket body, front grooves which correspond to the rollers of the front roller shaft one by one are arranged at the rear part of the front shaft bracket body at intervals, front sawteeth are arranged in the front grooves, and a certain distance is reserved between the front sawteeth and the edges of the rollers of the front roller shaft; the rear shaft bracket comprises a rear shaft bracket body, rear grooves corresponding to the rollers of the rear roller shaft one to one are formed in the front portion of the rear shaft bracket body at intervals, rear sawteeth are arranged in the rear grooves, a certain distance is formed between the rear sawteeth and the edges of the rollers of the rear roller shaft, front paper retaining sheets are arranged between the adjacent front grooves, and rear paper retaining sheets are arranged between the adjacent rear grooves.
