Description

Belt cutting device with rotating housing

The present invention relates to a belt cutting device, and more particularly to a belt cutting device having a rotating casing which can easily replace an element having a high wear rate while cutting the tape for a long time.

In order to more conveniently supply the tape in the case where it is continually required to cut into a predetermined length of tape (for example, in the case of packaging various products), a device for automatically cutting the tape has been used. Korean Utility Model Registration No. 20-0250041 (Patent Reference 1) discloses a "pulling guide device for an automatic belt cutting device". A belt pulling guide for an automatic belt cutting device includes: a belt mounting recess provided at a rear side; a control member disposed at an upper portion of the front side; and a cutting member disposed at a front side and having a dispensing hole, wherein the belt is mounted in the belt mounting recess The tape wound into a roll is cut into the required length by the cutting member and dispensed through the dispensing hole.

In Patent Reference 1, the upper casing covers the lower casing in a state where the belt puller is installed inside the lower casing.

In this case, since the belt puller is installed inside the lower casing, and the upper casing and the lower casing are joined together by bolts or the like, there are some inconveniences in the case where the components need to be replaced due to wear or any malfunction. This is because the user must loosen the bolts and release and separate the snails. Tie the various rollers with the retractor.

In order to solve such a problem, Korean Patent No. 10-0755919 (Patent Reference 2) discloses a "mechanism for automatically cutting a winding tape" in which an error sensor is mounted and a cutter is disposed on the front side for sliding The type is separated from the housing.

Unlike Patent Reference 1, Patent Reference 2 provides a cutter disposed on the front side, which cutter is separated in a sliding pattern. However, in order to replace an element due to failure or wear of the front side roller (for example, Patent Reference 1), since the upper case and the lower case must be separated from each other, Patent Reference 2 has a disadvantage that it is not easy to replace the element.

Further, the problems of Patent References 1 and 2 are that it is not easy to change the roller even after the upper casing and the lower casing are separated from each other.

In particular, the two rollers located near the front of the cutter and the upper roller of the approaching guide are rapidly worn, but it is not easy to replace such rollers.
