a correction tape

Abstract

The invention discloses a correction belt, which includes a tongue, a feed and take-up pulley, an upper and a lower housing, and a swing piece; the swing piece has a center ring, and at least two swing heads are distributed outside the center ring, and the swing heads are driven from the center ring to the swing head by the swing arm. Outer lead, the swing head has outer claws on the outside; there is an outer ring on one side of the feed pulley, and a number of internal teeth on the inner side of the outer ring; It fits to limit its rotation; the belt pulley is installed on the central shaft through the central hole, and the outer claw can contact the inner tooth; the outer claw and the inner tooth form the following relationship: the forward rotation operation of the belt pulley, and a certain inner tooth can be pressed A certain outer claw makes the swing arm swing inwards so that the inner tooth moves along the outer claw, and at the same time, the other inner tooth and the other outer claw are in a state of disengaging from each other. The oscillating part in the correction belt is in contact with the middle teeth of the feed pulley ring through the swing head claw, which can realize the one-way rotation of the feed pulley and prevent its reverse rotation, and can greatly reduce the noise generated during use.

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, ...

AI Technical Summary

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
