Description

[Detailed description of the invention] The present invention relates to a machine for blending paints.

BACKGROUND ART Paint mixing and blending machines that mix the contents of a paint mix by vibrating or rotating a paint hammer are well known. Previously known machines of this type were generally heavy, noisy, and had such high vibrations that it was necessary to anchor them to the floor of the structure or to some other equivalent object. Even with rubber or spring attachments, this type of machine pivoting tends to compromise the supports and sometimes even the machine mechanism. The large amount of movement required to mix the paint consumes a considerable amount of energy, so a high power source of power was required. Some known machines also took a significant amount of time to mix. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a paint mixing/blending machine having a relatively simple structure that completely mixes or blends fluids such as paint in a short period of time.

Another object of the present invention is to provide a paint mixing/blending machine in which the weight including the weight of the paint is substantially balanced during mixing, thereby reducing vibration, noise, and load. . Another object of the present invention is to provide a paint mixer that is quick and easy to install and remove.

Yet another object of the invention is to be energy efficient;
To provide a paint mixing/blending machine which is durable and effective for mixing with whiskers of various sizes.

In a preferred embodiment of the invention, a vertically disposed support plate with a central hole rotatably supports the bouli-shaped disk.

The disc is provided with a window that is large enough to accommodate the paint container, so that the paint container partially passes through the window and the central hole in the support plate. The circular bottom plate attached to the shaft is
It is freely supported by the disc and acts as a vertical bottom for fastening the cover inside the paint mixer. A vertical adjustment plate spaced from the first plate defines a clamping top. A rotary power source, such as an electric motor, drives the disk through wheels supported by a support plate and pressed around the disk. This movement transmits a turning motion longitudinally to the paint. A chamfered elastomer fixed to the circular base plate makes frictional contact with a complementary annular groove in the vertical support plate. As a result, when the disk rotates, the bottom plate also rotates around the marquee line perpendicular to the axis of the disk.
The paint sludge therefore revolves around its axis. The combination of turning and rotary movements rapidly mixes the contents of the crystal. Embodiments of the present invention will be described below with reference to the drawings.

The same reference numerals are used for the same parts in each figure. Referring to the drawings, and in particular to FIGS. 1 and 2, reference numeral 1 shows an overall embodiment of a paint compounding machine constructed in accordance with the present invention. The paint mixer is mounted on a pedestal 11 having a vertical support plate 12 made of steel, aluminum or other suitable hard material. A circular hole 13 is provided in the vertical support plate 12, preferably positioned in the center of the vertical support plate. The circular hole 13 is sized to receive a container 17 of paint to be dispensed as described in detail below. A flat pulley-like disc 14 with a window 15 is rotatably supported in the circumferential direction on a vertical support plate by means of plastic elastic wheels 16.

The wheels 16 are attached to the vertical support plate by short shafts which freely support them. These wheels are made of resilient urethane or some other hardwearing plastic or rubber material. Each of the wheels 16 is provided with a circumferential flange 19 encased in an annular groove 120 around the disc 14. The wheels 16 are in constant contact with the annular support plate 120 and act as a shock absorber for the vertical support plate 12. The disc 14 has an elastic actuator 21 which engages the disc at a point 22 within the annular groove 20.
is drivably supported by.

The drive wheel 21 is driven by a motor 24 as best shown in FIG.
It is fixed to the output shaft 23 of a rotary power source such as. Output shaft 2
3 passes through the hole 23 of the vertical support plate 12. As shown in detail in FIG. 3, the motor 24 is mounted on a rotating plate 26 that is swingably provided by bolts 27 attached to the vertical support plate 12. As shown in FIG. The slot 28 and pin 29 of the pivot plate 26 serve to limit the swinging of the pivot plate 26. Since the pivot plate is free to swing about the bolt, the weight of the motor 24 keeps the drive 21 in good frictional engagement with the annular groove 20 of the disc 14. Furthermore, with this configuration, there is no need for any noisy gears or gear trains to transmit rotational force to the disk. Referring again to FIGS. 1 and 2, a bearing pedestal 30 is mounted to the front of the disk between the edge of the disk window 15 and the rectangular entrance 31. Referring again to FIGS. The shaft 32 is freely supported within the bearing pedestal 30 and attached to one end of the shaft 32 is a flat disc or bottom plate 34 projecting from the rear end of the bearing pedestal coaxial with the vertical line 33 of the paint container 17. The bottom plate 34 is provided with a groove 35 concentric with its center and sized to accommodate containers such as towers having various diameters. As best shown in Figure 3,
The bottom plate 34 includes the window 15 of the disk 14 and the vertical support plate 1
It exits horizontally through the circular hole 13 of No. 2. As a result, the paint container 17 is minimally suspended from the vertical support plate 12 and is substantially counterbalanced within the paint mixer 10. Attached to the opposite end of the shaft 32 of the bearing pedestal is a chamfered or friction drive wheel 36 made of a suitable wear-resistant resilient material such as urethane, neoprene or rubber.

The friction driving mechanism 36 is placed on a complementary groove 137 cut into the surface of the disk 14. Disk complementary groove 37
has a sloped wall 38 which makes good frictional contact with the chamfered surface 39 of the friction drive wheel. When the disc 14 is rotated by the motor 24, the friction drive wheel also rotates, which causes the paint container 17 to rotate. The paint container 17 is vertically attached to the bottom plate 34 with a clamping plate 40 freely supported by threaded studs 41 aligned with the shaft 32 at intervals.

A notch 42 around the vertical mounting plate 40 serves to lock the handle 43 of the paint container 17 during rotation and turning of the paint container.
As best shown in FIG. 1, the yoke 44 is adjustably mounted to the disk 14 on the outer surface of the disk 14 or on the surface of the bearing pedestal.

The threaded undercut bolt 41 is inserted into the internally threaded hole 45 of the yoke 44. The movement of the vertical plate 40 toward or away from the bottom plate 34 is performed by rotating a vertical ring 46 vertically attached to a threaded shield bolt 41 between the yoke 44 and the clamping plate 40. If mixing is to be done with paint containers of substantially different sizes, loosen the yoke by removing the yoke setscrew 47 and tighten the yoke until the desired spacing to receive the paint containers is obtained and the setscrews are tightened. is slid along the guide path 48 of the disk 14. In one embodiment of the invention suitable for blending or dispensing paints, the rotary power source is a 1/4 horsepower AC electric motor with an output of 17.25 revolutions per minute, and the drive mechanism is:
The rotation speed of the paint container was four times that of the disk.

That is, the number of rotations of the paint container is four times that of the disk. As is clear from the above, the operation of the paint mixer is as follows. The yoke 44 is adjusted to an approximate height commensurate with the size of the paint container.

The paint container is attached to the bottom plate 341 by fitting the edge of the bonito into the groove 35 that matches the size of the paint container. The vertical mounting rod 46 is rotated until the paint container is secured between the bottom plate 34 and the cotton board 40. Then, raise the handle 43 of the paint container and insert it into the two spaced notches on the top slope.
Power is applied to motor 24 to drive disk 14, causing the light to rotate about its longitudinal axis while also rotating about its horizontal axis. The paint blender is operated at sufficient time intervals until the desired blending of the contents is achieved. For paint containers such as conventional water-based paints or oil-based paints, this time interval is approximately 3 lbs., depending on the temperature and condition of the contents before mixing. motor 24
is thus stopped, and by turning the rear wheel 46, the vertical plate 40
, then remove the paint container from the paint mixer. Although reference has been made to mixing and dispensing paints, not only solid substances but also various liquids can be used in paint containers without departing from the spirit of the invention.
