Description

Ball press roller sleeve device

Technical Field

The utility model belongs to ball press machine field especially relates to a ball press machine roller shell device.

Background

The ball press is provided with two cylindrical rollers with the same size, a roller sleeve is embedded on each roller, and a ball socket is arranged on the surface of each roller sleeve. The existing ball press roller sleeve roller surface ball socket is mostly circular, oval or square, so that the edge and inner edge of the roller surface ball socket are wider and the gap is large, and in the process of pressing pellets by the ball press, the acting force of the roller surface of the ball press on materials is weakened by the increased edge angles, so that the pelletizing rate and the pelletizing strength of material balls of the ball press are greatly reduced, and the working efficiency of the ball press is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a ball press roller shell device solves the low problem of ball forming rate and pelletizing intensity of ball press material ball.

In order to achieve the above object, the embodiments of the present invention adopt the following technical solutions:

according to an embodiment provided by the utility model, the utility model provides a ball press roller sleeve device, which comprises a pair of cylindrical roller shafts with the same size, wherein the roller shafts are sleeved with roller sleeves with the same size, and ball sockets are arranged on the roller surfaces of the roller sleeves; the ball socket is concave, the ball socket close to the edge of the roller surface is flush with the edge of the roller surface, and the ball socket at the inner edge of the roller surface is arc-shaped; the ball sockets are at least 2 rows.

To above-mentioned technical scheme, the utility model discloses still further preferred scheme.

Preferably, the sockets are arranged in 2 rows and are staggered with each other.

Preferably, when the number of the ball sockets is more than 2, the ball sockets are aligned with each other, the central lines of the ball sockets are on a straight line, and the shape of the middle ball socket is circular or elliptical.

Preferably, the ball sockets are the same size as the ball sockets in the row and the ball sockets in the middle are the same size.

Preferably, the length of the socket is: width: the depth is (1-1.5): 1, (0.2-0.5).

Preferably, the material of the roller surface is 9Cr2Mo or 9Cr15 SiMn.

The utility model is characterized in that:

in the process of pressing the pellets by the ball press, because the edge and the inner edge are reduced, the acting force of the roller surface of the ball press on the materials is enhanced, the pelletizing rate of the ball press is improved, the returned materials are reduced, the pellet strength is improved, and the working efficiency of the ball press is improved.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the roll sleeve device of the ball press comprises a pair of cylindrical roll shafts 2 with the same size, roll sleeves 1 with the same size are sleeved on the roll shafts 2, ball sockets 101 are arranged on the roll surfaces of the roll sleeves 1, and the ball sockets 101 are concave. The ball press hopper 3 is arranged between the two roll shafts 2, the hopper 3 is filled with materials, the roll shafts 2 rotate in opposite directions to extrude the materials, and the opposite ball sockets 101 on the roll surfaces are accumulated relatively to press the powdery materials into lump materials with a certain shape.

As shown in FIG. 2, a plurality of ball sockets 101 distributed on the roller sleeve 1 are arranged in a staggered manner, the ball sockets 101 and the edge of the roller surface are edge ribs 103, and an inner rib 102 is arranged between adjacent ball sockets 101 close to the inner side of the roller surface. The ball socket 101 close to the roll surface edge 103 is flush with the roll surface edge 103, and the ball socket part close to the roll surface inner edge 102 is in a circular arc shape and can be designed into a circular or oval shape.

The total number of the ball sockets 101 and the middle ball socket 104 is not less than 2 rows, and the ball sockets 101 are only 2 rows, 2 rows in fig. 2, and 3 rows in fig. 3 and 4. When the number of the sockets is 3 rows or more, the central socket 104 located in the center of the socket 101 is circular or elliptical, the central socket in fig. 3 is circular, and the central socket in fig. 4 is elliptical.

In one embodiment, the ball socket size meets the following requirements according to the reasonable layout of the actual roller sleeve size: the width of the edge and the inner edge of the roller surface of the roller sleeve is 2 mm-4 mm. As shown in fig. 5, the length b of the socket: width a: the depth ratio is (1-1.5): 1, (0.2-0.5).

In order to prevent the roller surface from being abraded too fast, the material of the roller surface is 9Cr2Mo or 9Cr15 SiMn.

This further narrows the ball and

socket edges

103 and 102 of the roll surface and reduces the clearance.

The ball sockets are uniformly distributed, the sizes of the ball sockets 101 and the middle ball socket 104 in the same corresponding position are the same, the balls are ensured not to be dislocated, the ball sockets are smooth in spherical surface and smooth in curve, the connecting part of a straight line and the curve is in transition, the central line of each ball socket is on the same straight line and is flush with the edge of the roller sleeve, and the long axis L of each ball socket is perpendicular to the edge of the roller sleeve.

The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
