CN211190555U - Feeding roller - Google Patents

Abstract

The utility model provides a feeding roller, wherein the surface of the feeding roller is provided with a plurality of feeding grooves which are uniformly distributed; the included angle between the feeding groove and the axis of the feeding roller is 1-7 degrees and inclines in the same direction. The feeding grooves and the axial line of the feeding roller are arranged at a certain included angle, so that when one rotating end of one feeding groove passes through the same plane position to the other end, the next adjacent feeding groove begins to pass through the same plane position, and the feeding uniformity is ensured. The feeding roller ensures that the feeding amount is uniform again in every rotating circle.

Description

Feeding roller

Technical Field

The utility model relates to a comminuted or crocus processing equipment accessory especially relates to a feed roller.

Background

In the prior art of crushing or grinding, the common structure of the feeding roller is that the surface of the feeding roller is provided with tooth-shaped feeding teeth or a feeding groove parallel to the axis of the feeding roller, and the structure can cause the problem of uneven feeding; the feeding device of the flour milling machine with the publication number of CN207357338U and the novel feeding roller with the publication number of CN208161706U can solve the problem of feeding uniformity, but can cause the problem of less feeding amount per rotation circle of the feeding roller.

Disclosure of Invention

The utility model provides an overcome above-mentioned defect, provide one kind and guaranteed every rotatory a week feeding volume again even feed roller of feed promptly.

The technical scheme of the utility model is that: a feeding roller is provided with a plurality of uniformly distributed feeding grooves on the surface; the included angle between the feeding groove and the axis of the feeding roller is 1-7 degrees and inclines in the same direction. The feeding grooves and the axial line of the feeding roller are provided with certain inclined included angles, so that when one rotating end of one feeding groove passes through the same plane position to the other end, the next adjacent feeding groove begins to pass through the same plane position, and the feeding uniformity is guaranteed.

The shape of the feeding groove on the radial section of the feeding roller is a kangaroo bag shape with different groove wall heights on two sides. The feeding groove is in a shape of a kangaroo bag on the radial section of the feeding roller, so that the feeding groove is easy to pour materials, and incomplete pouring of the materials in the feeding groove is avoided when the feeding groove is deep.

The rotating shaft of the feeding roller is fixedly connected with the rotating shaft of the stepping motor or the servo motor, and the feeding speed is adjusted by adjusting the rotating speed of the motor.

Preferably, the included angle between the feeding groove and the axis of the feeding roller is 2-3 degrees.

The maximum depth from the bottom point of the arc of the feeding trough to the middle point of the arc of the feeding trough on the outer circumference of the feeding roller is 17 mm.

The feed roller realizes even feed through the feed trough structure of slope when guaranteeing the feed volume to through the feed trough of "kangaroo bag" shape, guaranteed that the feed trough falls the material completely, avoid the "double-layered" phenomenon of material, be particularly suitable for single-roll milling machine.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1 and 2, in the feeding roller of the present invention, 9 feeding grooves 1 are uniformly distributed on the surface of the feeding roller; the included angle between the feeding groove and the axial line of the feeding roller is 2.5 degrees and inclines in the same direction. The shape of the feeding groove on the radial section of the feeding roller is a kangaroo bag shape with different groove wall heights on two sides.

The depth from the bottom point of the arc of the feeding trough to the middle point of the arc of the feeding trough on the outer circumference of the feeding roller is 10 mm.

Claims (5)
