Abstract
The utility model discloses a reassembling type pinch roller, its characterized in that: the roller sleeve is detachably sleeved on the excircle of the middle sleeve. The utility model discloses make things convenient for the installation of pinch roller, saved the replacement cost.
Description
Technical Field
The utility model relates to a dry process granulator, concretely relates to pinch roller of dry process granulator preforming mechanism.
Background
The dry granulator is applied to the production of granular products, wherein the tabletting mechanism is used for tabletting the powdery materials sent out by the feeding mechanism. The pressing wheel of the tabletting mechanism is heavy and is inconvenient to install; meanwhile, the thickness of the pressing sheet is different from the surface pattern, so that the whole pressing wheel is frequently replaced, and the replacement cost is high.
Disclosure of Invention
In view of the deficiencies of the prior art, the to-be-solved technical problem of the utility model is to provide a reassembling type pinch roller easy to assemble saves replacement cost.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
reassembling type pinch roller, its characterized in that: the roller sleeve is detachably sleeved on the excircle of the middle sleeve.
According to the technical scheme, the integral type of the prior art is changed into the split assembly type, when the pinch roller is installed, the pinch roller can be installed in parts, the installation weight is reduced, and therefore the installation is more convenient; in addition, when the pinch roller needs to be replaced, only the roller sleeve needs to be replaced, and replacement cost is greatly reduced.
Preferably, the inner hole of the roller sleeve is provided with spline grooves, and the outer circle of the middle sleeve is provided with spline teeth. The design facilitates the detachable connection between the roller sleeve and the middle sleeve.
Preferably, the length of the roller sleeve is larger than that of the middle sleeve, step holes are formed in two ends of an inner hole of the roller sleeve, inner and outer end cover plates are arranged in the step holes and axially limit the roller sleeve, and the inner and outer end cover plates are fixed on the middle sleeve through screws. The design structure simply realizes the axial positioning of the roller sleeve on the middle sleeve.
Preferably, an O-shaped ring seal is arranged between the hole wall of the inner hole of the stepped hole and the outer circles of the inner end cover plate and the outer end cover plate. The design ensures the sealing of the end surface of the pinch roller.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a reassembling type pinch roller comprises roller shell 1, middle cover 2 and inner tube 3, and middle cover 2 links to each other through welding mode is fixed with inner tube 3, and the excircle surface of inner tube 3 is equipped with helicla flute 4, and the centre of inner tube 3 is equipped with inlet tube 5 and outlet pipe 6, and the hole pore wall of inner tube 3 is located to the end of intaking of inlet tube 5, and the water outlet end of inlet tube 5 communicates helicla flute 4's top, and the hole pore wall of inner tube 3 is also located to the water outlet end of outlet pipe 6, and the end of intaking of outlet pipe 6 communicates helicla flute 4's end, roller shell 1 dismantled and assembled cup joints the excircle of middle cover 2, and the hole of roller shell 1 is equipped with. In order to realize the axial positioning of the roller sleeve 1 on the middle sleeve 2, the length of the roller sleeve 1 is larger than that of the middle sleeve 2, step holes are arranged at two ends of an inner hole of the roller sleeve 1, inner and outer end cover plates 8 are arranged in the step holes, the inner and outer end cover plates 8 are fixed on the middle sleeve 2 through screws, and an O-shaped ring seal 7 is arranged between the hole wall of the inner hole of the step hole and the outer circles of the inner and outer end cover plates 8. After the pinch roller is arranged on the pinch roller shaft 9, the pinch roller shaft 9 is provided with a water inlet channel 10 communicated with the water inlet end of the water inlet pipe 5, and a water outlet channel 11 communicated with the water outlet end of the water outlet pipe 6.
