Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, when the beating amount of the screw rod is large, the silicone dustproof ring is easy to wear, and the material will enter the bearing, resulting in the bearing being stuck, and the feeding screw and the inner ring of the bearing after the bearing is stuck. Sliding occurs between them, which eventually leads to the damage of the bearing and the conveying screw, and a new type of dry machine conveying device is proposed

Embodiment 1

[0029] refer to Figure 1-Figure 5 , a new type of dry process machine feeding device, including a fixed shell 1 and two feeding screw 3, the feeding screw 3 is made of stainless steel, adopts a new heat treatment process, the surface hardness is high, and the wear resistance and corrosion resistance are greatly improved There is a mounting opening on one side of the fixed shell 1, and the bearing seat 2 is fixed by bolts in the mounting port. There are two bearing cavities in the bearing seat 2, and the outer circumferential walls of the two feeding screws 3 are equipped with oil-free Bearing 12, and two oil-free bearings 12 are respectively located in two bearing cavities, oil-free bearings 12 carry out radial positioning to feeding screw 3, can avoid the pollution that lubricating oil brings thoroughly, set up between two bearing cavities The communicating hole 15 communicates the two bearing cavities through the communicating hole 15, so as to facilitate the circulation of...

Embodiment 2

[0031] refer to Figure 1-Figure 5, the present invention provides a new technical solution: a new type of dry process machine feeding device, including a fixed shell 1 and two feeding screw 3, the feeding screw 3 is stainless steel, adopts a new heat treatment process, the surface hardness is high, The wear resistance and corrosion resistance have been greatly improved. One side of the fixed shell 1 is provided with a mounting port, and the bearing seat 2 is fixed by bolts in the mounting port. There are two bearing chambers in the bearing seat 2 and two feeding screws. The circumferential outer wall of 3 is equipped with oil-free bearings 12, and the two oil-free bearings 12 are respectively located in the two bearing cavities. The oil-free bearings 12 radially position the feeding screw 3, which can completely avoid the friction caused by the lubricating oil. pollution, there is a communicating hole 15 between the two bearing chambers, and the two bearing chambers are conne...

Abstract

The invention belongs to the field of dry method machine material conveying, particularly relates to a novel dry method machine material conveying device, and aims at solving the problems that when the jerk value of an existing screw is large, a silica gel dustproof ring is prone to being abraded, materials enter a bearing, the bearing is stuck, after the bearing is stuck, sliding is generated between a material conveying screw and a bearing inner ring, and the material conveying screw is damaged. In order to solve the problem that a bearing and conveying screw rods are damaged finally, according to the following scheme, the device comprises a fixing shell and the two conveying screw rods, a mounting opening is formed in one side of the fixing shell, a bearing seat is fixedly connected into the mounting opening, and two bearing cavities are formed in the bearing seat. By means of the oil-free bearing, a layer of air film can be formed between the material conveying screw and the oil-free bearing, a certain supporting effect on the material conveying screw is achieved, the friction force between the material conveying screw and the oil-free bearing is reduced, meanwhile, pollution caused by lubricating oil is thoroughly avoided through the oil-free bearing, and the air pressure entering the bearing cavity can be conveniently adjusted through the use of the adjusting mechanism.

Description

technical field [0001] The invention relates to the technical field of dry process machine conveying, in particular to a novel dry process machine conveying device. Background technique [0002] Dry granulation is to mix the drug and diluent, disintegrant, lubricant, etc. according to the mixing method of the powder, and then process it 1-3 times by rolling or open rubber mixing machine, and press it into a sheet with the required hardness, and then use it The method of crushing into granules by the swing granulator, and the conveying device for conveying the raw materials are required in the dry granulation rolling process. [0003] The traditional dry granulator generally adopts the feeding screw to forcibly feed the material to the extrusion wheel. Through the extrusion of the extrusion wheel, the material particles are combined to form a band or tablet, and then the desired particle size is obtained through granulation. For the finished product of particle size, for the...
