FR2548072A1 - Mill (grinder) for adhesives for coating the ground - Google Patents

Abstract

An assembly A comprising the abrasive disc and its control, plus manipulating hand grips, plus a system for placing to rest using springs. The abrasive disc with very coarse emery grit is immersed in water. It carries grooves on its working face, allowing good circulation of water and removal of waste between the contacting surfaces. The water must act both as a lubricant (reduction in the coefficient of friction), and as a coolant, it not being permitted for the adhesive to change in plasticity. An assembly B comprising the leaktight casing with regulated water inlet and discharge of water without pressure. Movement of the appliance on castors.

Description

GRINDER FOR ADHESIVES
FLOORING.

 The invention consists in removing, by grinding, the adhesives used to fix the floor coverings.

INTEREST OF THE SYSTEM
Currently, there is only one effective way to remove adhesives: it is the pricking of the ground by hammering, either manually with a hammer, or with a pneumatic machine throwing balls on the ground.

 Solvents do not make the floor clean enough.

 The advantage of the invention is to make the work less strenuous and makes it possible to obtain, by this process, a clean slab without roughness.

 This machine can enter the range of DIY devices as well as in the industrial sector.

DESORIPTION OF StZS E
The invention is based on physical reasoning
Use of a very large grain abrasive disc with grooves.

Selected abrasive: Emeri, very wear-resistant material.

 disc is enclosed in a casing provided with a seal at its lower part. It bathes abundantly in water and is hindered by an engine. This water must serve both as a lubricator (reduction of the coefficient of friction) and as a cooler. The glue does not change plasticity.

The large grains of emery and the grooves allow good circulation of water and the elimination of waste between the surfaces in contact.

 The drawing plate I gives a mechanical principle.

TOGETHER:
I) - Handle of operation on which a vertical force is exerted during the grinding operation.

 2) - Positioning finger of the operating handle (2 positions at 900) for rough grinding of obstacles.

3) - Electric motor control push button
4) - Flange motor 5) - 4 spring guide screws thus pocketing the rotation of A with respect to B.

6) - Spring support flange
7) - Lifting springs of assembly A after removal of the vertical force. The grinder is moved without friction of the disc on the ground.

8) - Coupling sleeve
9) - Transmission shaft
I0) - Chuck
II) - Abrasive disc support
I2) - Abrasive disc
13) - 2 bearings locked in rotation and axially in a sheath.

I4) - Cover with gasket
I5) - Lubricating the sleeve and ENSREBLE B bearings
I6) - Protective casing
I7) - The seal is fixed to the protective casing
It follows the deformations of the ground and ensures a good seal I1 is made of foam.

 Alternatively, this seal can be formed from a plastic tube filled with water.

I8) - Regulated water inlet in the box
I9) - Water drainage
20) - Arm with multidirectional casters. This shifting system can be improved for a better approach to working near obstacles (walls). On the plan, it is only a mechanical example.

 Quick detachment of A and 8 nar dismounted eye bolts and change of the disc.

DRAWING PLACE 2 (Detail, mounting the abrasive disc)
II - Abrasive disc support, rigid, with a bonded rubber sheet (water-resistant glue)
Its contact face with the abrasive disc must be well placed and not hollow as in most commercial media.

I2) - Abrasive disc
- very rigid emery support
- emery grains amalgamated on a high thickness water resistance)
- grooving in emery for water circulation
21) - mounting of the abrasive disc on its support by countersunk head screws with hexagon socket
22) - Two lugs mounted in opposition immobilize the rotating disc.

SHORT SUMMARY OF THE DEVICE
(Rep. I to 15 Plate I
A set Â)
(Rep. II, I2, 21, 22, plate II comprising the abrasive disc and its control, more operating handles, more system of resting by springs.

 The abrasive disc with very large grains of emery is bathed in 11 water. It has grooves on the working surface allowing, between the surfaces in contact, good lattice formation and the elimination of waste.

 The water must serve both as a lubricator (reduction of the coefficient of friction) and as a cooler, the adhesive should not change its plasticity.

 A set B (ref. I6 to 20 Plate I) comprising the sealed casing with regulated water inlet and pressure-free water discharge.

Moving the device on casters.
