US 11,634,246 B2 · Dispenser for stretch film

Abstract

An electric stretch film dispenser includes a frame and a power unit. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly provided with a film mounting unit and a film dispensing unit. The film dispensing unit has a first roller and a second roller. The first roller is connected with a first power drive unit. The first power drive unit is configured to drive the first roller to rotate. When in use, the film of a film roll is pulled due to different rotational speeds of the first roller and the second roller. Thereby, the electric stretch film dispenser can automatically generate tension when used, so it can be used to pack articles at different heights. The electric stretch film dispenser facilitates the application of the film and increases the tension of the film.

Dependent claims

Electric dispenser for stretch film, comprising:

a frame, provided with
a film mounting unit and
a film dispensing unit, the film dispensing unit comprising
a first roller for guiding a film and
a second roller for guiding the film,
at least one control unit,
characterized by
at least a first drive unit for driving the first and/or the second roller to rotate,
wherein the first drive unit is an electric motor, and wherein the dispenser comprises a power unit, for powering the first drive unit,
comprising at least one sensor configured for providing a sensing signal that is proportional to the pulling force exerted on the handle, and wherein the control unit is configured to adapt the speed of the first drive in dependency of the sensing signal;
further comprising a force-controlled drive whereby the speed of film feeding is determined by the tensile force that is set on the device such that the stretch on the film remains consistent.
