Description

Medicine crushing roller

Technical Field

The utility model relates to a medicine processing equipment field, concretely relates to roller is smashed to medicine.

Background

The pulverizer is a device widely used in medicine processing, and is used for pulverizing large-particle medicine raw materials into small-particle materials according to requirements. The traditional pulverizer can be divided into the following parts according to the processing mode: beating, shearing, grinding, rolling, etc. The roll-type pulverizer grinds materials through two pulverizing rolls which rotate oppositely.

As is known, when a material is rolled by the crushing roller, a large amount of heat is generated to cause the temperature of the crushing roller to rise, and especially when large-batch continuous crushing is carried out, the accumulated heat cannot be effectively released due to continuous work of equipment, so that the phenomenon is more obvious. High temperature not only can make the material receive the damage, also can cause certain influence to the life of crushing roller simultaneously. If the temperature of the crushing roller can be effectively reduced, the phenomenon can be improved.

Detailed Description

The drug crushing roller shown in fig. 1-3 comprises a roller body, wherein the circumferential surface of the roller body is provided with crushing teeth 14, and the center of the roller body is provided with a water cooling channel 15 extending along the length direction of the roller body. The cooling water that flows through in the water-cooling channel 15 cools down the roller body, of course, because the roll body is the gyration part, so the both ends of smashing the roller should be respectively through rotary joint 16 and water pipe intercommunication, water-cooling channel 15 includes a plurality of oval chambeies that extend along roll body length direction and connects the neck chamber in two adjacent oval chambeies and constitutes, and water-cooling channel 15 is favorable to the water to slow down like this, and it is long when improving the heat transfer, and is favorable to increasing heat transfer area.

However, this kind of dysmorphism water-cooling channel 15 structure is in actual processing, and the processing degree of difficulty is great, so the utility model discloses better way can also be, the roll body includes that two cross-sections are semicircular semi-axis 21, semi-axis 21 constitutes the roll body through the connector locking of setting up two ladder tube-shapes at the roll body both ends. The both ends of semi-axis 21 are provided with shoulder section 22 and minor axis section 23 along the direction of keeping away from the roll body middle section in proper order, the connector is including water piping connection section 24, shoulder linkage section 25 and the minor axis linkage section 26 that connects gradually. The short shaft sections 23 of the two half shafts 21 are inserted into the short shaft connecting section 26 of the connector together to form a split joint, and the shoulder sections 22 of the two half shafts 21 are inserted into the shoulder connecting section 25 of the connector together to form a split joint. The shoulder section 22 of the half shaft 21 and the shoulder connecting section 25 of the connector are correspondingly provided with at least two groups of bolt holes 27, and the connector and the half shaft 21 are locked through fastening bolts penetrating through the bolt holes 27. The water pipe connection section 24 is connected to the rotary joint 16.

In the working process of the crushing roller, the cooling water in the water cooling channel 15 can effectively cool the crushing roller, so that the crushing roller is maintained in a low-temperature state, the material is prevented from being damaged by high temperature, and the service life of the crushing roller is prolonged. Meanwhile, the water cooling channel 15 formed by the elliptical cavity and the neck cavity has a larger heat exchange area between cooling water and the crushing roller, and the cooling efficiency is improved.

Of course, in consideration of the sealing performance of the crushing roller body, two sealing grooves 28 extending along the length direction of the roller body are arranged on the opposite surfaces of the two half shafts 21, the sealing grooves 28 are located on the two sides of the water cooling channel 15, and sealing strips are arranged in the sealing grooves 28. The water body can be effectively prevented from leaking through the design of the sealing groove 28 and the sealing strip.

In order to be convenient for be connected roll body and crushing motor, be provided with on the minor axis linkage segment 26 of connector is global ends strip 29, and bearing 30 and driven gear 31 cover are established on minor axis linkage segment 26 to it is spacing to constitute circumference through ending strip 29. The driven gear 31 may be connected to a driving gear driven by a pulverizing motor to transmit power, and the bearing 30 may be used to install the roller body in the pulverizing barrel.
