Abstract

PURPOSE:To extremely narrow the contact surface of a roller with a rail and reduce rotational resistance and further certainly restrict axial slippage of a drum by forming rollers so as to be axially reduced in diameter in order and further to be opposed to each other with the rail of the drum positioned therebetween. CONSTITUTION:Rollers 1 are shaped to be reduced in diameter successively in axial direction, while the axial line 5 of a drum 2 is slanting from a horizontal plane by an appropriate angle alpha. Rollers 1 are supported on a frame 8 through bearings 9 at least at two points on the axis of the drum 2 with axial lines 7 of shafts 6 making the same slant angle alpha as the drum 2, with at least two rollers 1 opposed to each other at more than two points on the same face perpendicular to the axial line 5 of the drum 2. By placing rails 10, circling the periphery of the drum 2, on respective rollers 1, the drum 2 is rotatably supported at a predetermined position with the slant angle.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for an inclined rotating drum, and reduces the contact area between the rails wound around the drum and the supporting rollers to reduce rotational resistance. The purpose is to prevent the deviation f of the drum position in the 411p direction by bending the rail to substantially "γZ" using several rollers. At the same time, at Lichuan, and with the same number of images on the picture plane as the drum @ line, and with at least two rollers facing oppositely to each other, 1. In addition, at least two rollers on the drum axis In this point, the drum is supported in relation to the machine frame, and by placing rails wound around the drum's outer periphery on these rollers, the drum is tilted and supported rotatably at a predetermined angle [7. The form is not described in detail in the drawings, but it is a first-order curve. 1 has a shape that is angularly compressed in the axial direction with a roller, such as a circular trapezoidal shape or a 131-tooth shape. The rotating drum is used for stirring, mixing, etc., and the openings 3 and openings at both ends can be closed. Only the back side α is sloped.Therefore, one roller is used, and its 41:6 thin #7 is connected to the side slope α of drum 2.
Similarly 17, l'Wi -l! with axis 5 of drum 2! At least two rollers 1 are oriented in opposite directions to each other at two or more points on the father face, and at least two points on the shaft leg of the drum 2,
The machine frame 8 is mounted on a shaft using a bearing 9. 10 rails 10 are wound around the outer periphery of the drum 2, and by placing the rails 10 of the kneaders on each roller 1, the drum 2 can rotate freely at a predetermined position with an oblique angle α of 11. Supported by

The fear of the roller 1 (: Th power rotation is the same as the shown tide) or 71 may be the same.The chain wheel 1 which is driven by the drum 2 Vcri-i and the chain band 11 is phantom and is driven by the ``aLIII 1 machine 1z''.
8 is engaged with this chain band 11 (7 is adapted to rotate).

The rollers should be bent, and the steepness of the heel should be longer than the width of the rail 1 (), and the edge of the rail φ10 should be inward from the middle edge of the roller 10.
(If you make it sensitive to 1, even if it's just that, Ittsuki 9 is L7
There is no, but I put tsuba 21 on roller 111 + 1j.
If you set it to 2, you can actually self-hire the escape. At this time, if a relief 22 is formed on the inner surface of the guard z1, the rail 1
Contact with the surface can be prevented, and an increase in rotational resistance can be prevented.

Roller l's dog is td 1. <I, although it is not necessary,
All of them are arranged as a diagonal, and they are placed at three points on the plane that intersects the axis 5 of the drum 2, 7 times - half the distance with respect to the center C of the drum 2, and at an equal central angle of 1 and θ. When the center roller 1' is traced to this center C,
The rigid support 5 of the drum 2 is reliably rested on the diagonal position of the foot 1, and the drum 2 rotates comfortably and stably, so that it does not shake.

The rollers 1 have shafts 6 rotatably supported by bearings 9, and a machine frame 8 that supports these bearings 9 has a horizontal section; Supported slopes 34f on both sides.These slopes 3
A long hole 35 is bored in the longitudinal direction of the drum 2, and by adjusting the position of the bolt/nut 36 that attaches the bearing 9 to meet this long hole 85, the track 10 of the drum 2 can be prevented from wearing out.
7, the contact between the roller 1 and the rail lO can be reliably maintained.

In the drawing, 41 is the transmission #l button wheel coaxial with the chain wheel 13, and 42
A bearing that rotatably supports the shaft 48 of the Hakowara Chain Tanbo, 4
4 is a transmission copper band, 45 is a frame part provided on the base part 8z to support this bearing 48, and the @n wire 46 of the board 48 is also supported at a bevel angle α.

In the illustrated support device, by placing the rail 10 of the drum 2 on the roller 1, the rail 10 is substantially held between a plurality of rollers l whose diameters are gradually reduced in the @11 direction. It will not shift downward. roller 1
The contact area between the rail 1o and the rail 1o is extremely narrow and does not provide much resistance to rotation.

Even if the rail IO wears out, the rail IO is always kept at a predetermined position on the line 5 because the rollers (1) are oriented in the opposite direction. Therefore, when raw materials are put into the drum z and the drum 2 is rotated, the raw materials are mixed inside and taken out to the outside.

According to the present invention, the rollers that land on the drum rail and support it are configured to gradually reduce their diameters in the axial direction Ti1l, and are arranged in opposite directions so as to sandwich the sheet φ in the real 1st direction.
The contact surface between the roller and the blade can be made extremely narrow, so the rotational resistance can be made as small as possible, and the deviation of the axis of the drum edge is reliably prevented, allowing the drum to always rotate at a predetermined position, without the occurrence of overshooting. Of course, it has divine features such as being able to prevent the occurrence of loud noises.
