Correction tape

Abstract

The invention discloses a correction tape. The correction tape comprises a tongue piece, a tape conveying wheel, a tape collecting wheel, an upper shell, a lower shell and a swing piece, wherein the swing piece is provided with a central ring, at least two swing heads are distributed outside the central ring, the swing heads are led out from the central ring by swing arms, and the swing heads areprovided with outer clamping jaws on the outer sides; one side of the tape conveying wheel is provided with an outer ring, and a plurality of inner teeth are arranged on the inner side of the outer ring; the swinging piece is arranged on a central shaft of the lower shell through the central ring, and the central shaft is matched with the central ring to limit rotation of the swinging piece; the tape conveying wheel is mounted on the central shaft by a central hole, and the outer clamping jaws can be in contact with the inner teeth; and the outer clamping jaws and the inner teeth form the following relationship that the tape conveying wheel is in a forward rotating operation, a certain inner tooth can enable the corresponding swing arm to swing inwards by pressing an outer clamping jaw toenable the inner tooth to move along the outer clamping jaw, and meanwhile, the other inner tooth and the other outer clamping jaw are in a mutually separated form. According to the correction tape, the swing piece is in contact with the inner teeth of the outer ring of the tape conveying wheel through the clamping jaws of the swing heads, so that one-way rotation of the tape conveying wheel is realized and reversal of the tape conveying wheel is prevented, and the noise generated in use can be greatly reduced.

Description

technical field [0001] The invention belongs to a stationery, and relates to a device for reeling tape conveyed by take-up and feed rollers, and a pressure head to cover the functional film on the reel tape on the paper and roll up the base tape for recycling. Specifically, it is a device A coiled correction tape. Background technique [0002] Most of the correction tapes are rolled up for people to use. The base tape is used as a carrier, and a layer of correction film is attached to the carrier, and it appears in the form of winding. Usually, it is equipped with tape release, base tape recovery and correction. The mechanism for peeling off the diaphragm is still called the correction tape together with the winding tape of these mechanisms. [0003] In the traditional correction tape, the reel is installed on the feeding wheel, pulled by the reel, and driven by gears, so that the sending wheel is released and recovered by the take-up wheel. The film is pressed and moved, ...

Problems solved by technology

[0006] This structure brings problems in the use of the correction belt. The strong resilience of the pawl strengthens the degree of collision between the ratchet and the pawl, and the dense distribution of teeth makes the collision very frequent, resulting in The noise of clicking, clicking, clicking... will still have a certain impact on others in environments with special requirements for quietness, such as examinations or lectures
