Description

Toothed rolling disk

Technical Field

The utility model relates to a pelletization rolling disc field specifically is to relate to a take tooth rounding carousel.

Background

The granulator mainly comprises a feeding system, a stirring system, a granulating system, a transmission system, a lubricating system and the like, and is widely applied to the pharmaceutical industry, the chemical industry and the food industry. The granulator can be classified into a feed granulator and a biomass energy granulator.

Thereby the pelletization process of granulator need through the rounding carousel, through the rotation of rounding carousel, thereby will press the material rounding below and accomplish the pelletization, and traditional rounding carousel's pelletization form is single, and is not high to the pelletization standard support nature of multiple shape specification, consequently need redesign one kind can support the rounding carousel of multiple specification pelletization standard.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, a toothed rounding turntable is provided.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a take tooth rounding carousel, includes the carousel body, the center department of carousel body is equipped with a plurality of and is circumference evenly distributed's bolt hole, and the center department of carousel body is equipped with one from the machined surface along its axially sunken heavy groove of dodging, it has the hobbing portion that is used for carrying out the rounding pelletization to the material that contacts to process on the carousel body and the one side quotation of material contact.

Preferably, the tooth profiles of the rolling tooth parts are distributed in a 'well' shape in the transverse and longitudinal directions.

Preferably, the tooth forms of the rolling tooth parts are arranged in a sector shape along the circumferential direction of the turntable body.

Preferably, the included angle between the two tooth surfaces of each tooth socket of the hobbing part is 90 °.

Preferably, the included angle between two tooth surfaces of each tooth socket of the hobbing part is 60 degrees, and the tooth space is 0.3 mm.

Preferably, the tooth pitch of the rolling tooth part is 0.3 mm.

Preferably, the tooth pitch of the roller tooth part is 1 mm.

The utility model has the advantages that: the rounding turntable adopts a heat treatment process, the whole turntable is firm and is not easy to deform, the tooth surface has high wear resistance, and is smooth and free of burrs. The hobbing part obtained by planing or knurling can be in multiple arrangement forms, and the tooth surface shape and specification also have multiple specifications for replacement.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

Referring to fig. 1 to 4, a gear-equipped rounding turntable comprises a turntable body 1, wherein a plurality of bolt holes 2 which are uniformly distributed in the circumferential direction are formed in the center of the turntable body 1, an avoidance sinking groove 3 which is recessed along the axial direction from a processing surface is formed in the center of the turntable body 1, and a gear hobbing part 4 for rounding and granulating a contacted material is processed on the disc surface on one side of the turntable body 1, which is contacted with the material. The device is used for processing processes such as rounding granulation, centrifugal coating and the like, the rotary table is divided into three specifications of coarse teeth, fine teeth and an optical disc, and the rotary table body 1 can be replaced according to needs to cut materials in different sizes and control the size of pills.

The turntable body 1 is subjected to a heat treatment process, so that the whole turntable is firm and difficult to deform, and the tooth surface of the turntable is high in wear resistance, smooth and free of burrs. The serrations 4 are formed by planing or knurling.

The tooth-shaped arrangement of the rolling tooth parts 4 has two modes, one mode is that the tooth shapes are distributed in a 'well' shape in the horizontal and longitudinal directions. Secondly, the turntable bodies 1 are arranged in a fan shape along the circumferential direction. The rear end of the turntable body 1 can ensure that the cutting tooth profiles are uniformly distributed, and the process consistency is ensured.

As shown in fig. 2, the included angle α 1 between the two tooth surfaces of each tooth slot of the rack 4 is 90 °.

As shown in fig. 3, the included angle α 2 between the two tooth surfaces of each tooth slot of the rack 4 is 60 °, and the tooth space d2 is 0.3 mm.

As shown in fig. 2, the tooth pitch d1 of the rack 4 is 0.3 mm.

As shown in fig. 4, the tooth pitch d3 of the rack 4 is 1 mm.

The tooth form angle can be changed according to the requirement, the cutting edge angle can be increased or reduced, and different material cutting requirements are met, as shown in fig. 2 and 3;

the space between teeth can be changed according to the requirement, the tooth space density can be increased or decreased, and different material cutting requirements can be realized, as shown in fig. 2 and 4.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
