MIXING DEVICE AND APPLICATOR FOR SEALANTS

Abstract

Mixing device and applicator for sealants formed by a main body and a handle (1), wherein the main body comprises a container-carrying sheath (7), a rotating cylinder (14), a gear module (11) that can be coupled to a rotor and a set of mechanisms that eject the sealant material. By actuating a trigger (2), a speed regulator (3) and a rotation selector (4) present in the handle (1) in a first action the cylinder (11) rotates in one sense mixing the material and in a second action it changes the sense of rotation and by actuating a cylinder locking system (19 and 20) present in the main body the device ejects the sealant material.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0033] According to the disclosed illustrations and always respecting the numbering present therein, a preferred, but not limiting, embodiment of the invention is explained below wherein the mixing device and applicator for sealants comprises a handle (1) which houses a trigger (2), a rotation speed regulator (3) and a rotation sense selector (4).

[0034] A modular casing or enclosure (5) rests on said handle (1) which is closed in the rear portion by means of one of said modules and in the front portion by means of a closing bushing (6) fastened thereto preferably by means of screws.

[0035] In the front portion of the device a sheath (7) is arranged with a tightening head (8) which is coupled to the device preferably by means of an anchoring system made up of a series of protuberances (9) present therein and introduced through secured tracks (10) existing in the front portion of the device.

[0036] The modular casing or enclosure (5) houses on the inside thereof the mechanisms, transmissions and gears described below; [0037] A rotor (23). [0038] A gear module (11) with a clutch coupled to a rotor (23) powered by an electrical current or by means of a pneumatic system. [0039] An extendable shaft (12), projected from the gear module (11) and resting on an axial bearing (22), which is made up of a first fixed section (12.1), a second movable section (12.2), a third also movable section (12.3) both with longitudinal movement and a plunger element (13) of the pistons present in the containers (21) of sealant material. [0040] A cylinder (14), projects from the closing bushing (6), coupled to said gear module (11) and which rests on a radial bearing (18) arranged thereon. The arrangement of the mentioned bearing on the cylinder is made between a contoured projection (15) present in the middle portion thereof and the closing bushing (6) present therein. The mentioned cylinder (14) has tracks (10) with housing in the front portion thereof. [0041] A telescopic guiding system of the extendable shaft is located inside the cylinder (14) and is made up of an adapter (17) with a geometric transition from circular to hexagonal shapes in a preferred embodiment located between the gear module (11) and a telescopic guide made up of two movable sections (16.1 and 16.2) with an identical hexagonal geometric shape and different sizes which is dragged by the extendable shaft (12) itself. The circular portion of the adapter (17) is extended in a linear sense at a distance long enough for the container of the sealant material to fit proportionally.

[0042] Said closing bushing (6) incorporates a system for locking or releasing the rotation of the cylinder preferably made up of a retention rod (19) with a lever head and guiding and closing means (20) thereof.
