Description

Correction tape

Technical Field

The utility model relates to the technical field of correction tapes, in particular to a correction tape.

Background

The correction belt generally comprises a correction head, a belt wheel and a waste belt wheel, the belt wheel releases a belt, the belt is recovered by the waste belt wheel after passing around the correction head, when in use, the correction head presses the belt on the surface to be covered and performs dragging operation, the belt is continuously pulled out from the belt wheel along with the dragging operation, the covering on the belt is transferred from the belt to the surface to be covered, in order to rotate the waste belt wheel to recover the belt, a gear meshing transmission structure is arranged between the belt wheel and the waste belt wheel, specifically, the belt wheel is provided with a first gear, the waste belt wheel is provided with a second gear, the first gear is meshed with the second gear, therefore, during the dragging operation, a linkage motion is formed, namely, the belt is continuously pulled out from the belt wheel along with the dragging operation, the belt drives the belt wheel to rotate, the first gear rotates to drive the second gear to rotate, the second gear rotates to drive the waste belt wheel to rotate, therefore, the whole process that the belt wheel releases the belt and the waste belt wheel recovers the belt at the same time is realized, namely the using process of the correction belt.

For a long time, in order to complete the above process, the belt wheel rotates to drive the waste belt wheel to rotate, which is the basic structure of the correction belt and is also the current optimal structure considered in the industry, and such design not only realizes the function, but also has simple structure and stable and reliable transmission, so the basic structure forms the thinking formula in the industry and is an irreplaceable part.

The applicant originally follows the above-mentioned thinking and also follows the structural design based on the basic structure in the existing product, and meanwhile, the applicant wishes to further improve the performance of the correction tape by optimizing the material and/or structure, such as improving the silence, the anti-loosening performance, the coating smoothness and the like, however, the applicant finds that the belt in the belt wheel is less and less along with the consumption of the belt in the belt wheel, and the force in use needs to be larger, that is, the force in use is gradually increased in the service life cycle of the correction tape, and the force cannot be stably maintained, so that the user experience is affected, and the applicant cannot break through under the thinking.

Therefore, the applicant has conducted continuous and more intensive studies on the correction tape and has obtained certain results of the study: 1. when the belt wheel is assembled in the correction belt, the belt wheel has a certain tightness, the belt wheel cannot be too loose after being assembled, otherwise the belt wheel is easy to loose, and the belt wheel has a certain tightness, so that when the belt wheel is pulled, a certain rotation resistance, namely a certain resistance moment, needs to be overcome, a calculation formula of moment is that force is multiplied by a moment arm, and the resistance moment, namely the resistance moment is multiplied by a resistance arm, therefore, along with the release of the belt, the distance between the belt and the rotating shaft of the belt wheel is reduced, so that the main moment which overcomes the resistance moment is reduced, and therefore, a larger force is needed to generate an active moment which overcomes the resistance moment, namely, the correction belt is used to the back, one of the reasons that the larger force is needed to drag is generated, 2, because the first gear is meshed with the second gear, the transmission ratio cannot be changed, therefore, when the belt wheel releases the belt, a belt roll of the belt wheel drags and the rotating shaft of the belt wheel can generate a certain relative rotation, the relative rotation is forced to occur, under the condition, the rotation of the belt wheel dragging the belt wheel needs to be solved simultaneously, the rotation of the belt wheel and the rotation of the waste belt wheel driven by the belt wheel are solved, namely, the relative rotation is superposed with the resisting moment inside the belt wheel 1, and therefore the change of the force applied by the dragging belt is more obvious. As can be seen from the foregoing, the problems, the causes of the problems, and the analyses thereof are complicated, and the applicant has not seen the problems, the causes of the problems, and the analyses thereof proposed by other persons or companies in the industry from the existing published materials or products, and has focused on the studies by the applicant to solve the problems.

In this example, the driving wheel 5 is one, the driving wheel 5 is provided with a first gear 8, the waste belt wheel 3 is provided with a second gear 9, and the first gear 8 is meshed with the second gear 9. The design is favorable for adapting to the correction tape with tense space, and has the advantages of simple and compact structure.

In order to further simplify the construction and increase the compactness, the belt 1 between the belt wheel 2 and the correction head 4 is in contact connection around the drive wheel 5 in this example, and the belt 1 drives the drive wheel 5 to rotate via this contact connection when the belt 1 moves.

The side of the belt 1 on which the non-coated layer is located is in contact connection around the drive wheel 5. By the design, the cover layer of the belt 1 is prevented from being adhered to the driving wheel 5 due to contact connection, and the use performance of the belt 1 is guaranteed.

The transmission wheel 5 is provided with a friction increasing portion 6, and the friction increasing portion 6 is in contact connection with the belt 1. The design is favorable for increasing the contact friction force and guaranteeing the driving effect of the belt 1 on the driving wheel 5. In this example, the friction increasing portion 6 is a friction ring which is fitted on a driving column 10 of the driving wheel 5.

As shown in fig. 1, the transmission wheel 5 is located between the pulley 2 and the waste pulley 3, and on the side of the pulley 2 that releases the belt 1. The structure layout is favorably carried out in the correction tape with tense space, and in addition, the contact area of the contact connection between the belt 1 and the driving wheel 5 is favorably increased along with the use, so that the driving effect of the belt 1 on the driving wheel 5 is more favorably ensured.
