Description
Technical field
What the present invention relates to is the equipment that a kind of polymer and masterbatch carry out mixing, and especially also adding in compound has sand, and the Spiral internal mixer of prerequisite work is made in the product compression molding for model stamping machine.
Background technology
Existing Spiral internal mixer, can be referred to as continuous internal mixer again, is mainly used in the heating mixing of polymer and masterbatch.It mainly comprises frame, frame is mounted with the machine barrel of band feed hopper, and be axially mounted with the screw rod that one end is connected with motor by reducing gear in machine barrel, another of machine barrel is provided with discharging opening relative to the other end arranging feed hopper; Described machine barrel is in horizontal substantially, the heat preserving casing of band heater is coated with outside it, it is when barrel heat, by the rotation of screw rod, is done under the state that the compounds such as the polymer sent into by feed hopper in machine barrel are heated again to stir fully, realize compacting work simultaneously, finally send from the other end discharging opening of machine barrel and meet the compound that work is carried out in next procedure, as carried out compression molding or punch forming etc.
But existing Spiral internal mixer uses conventional polymer raw material etc. substantially, therefore seldom exquisite to the configuration of power, general dynamic power machine can both be satisfied the demand, therefore, the product that existing Spiral internal mixer is suitable for is comparatively single, the mixed material work being blended with sand in compound cannot be used for, because be mixed with the building stones such as sand in mixed material, resistance will be increased, and then increase the configuration requirement of dynamic power machine, otherwise the service life of dynamic power machine will be reduced, if height joins dynamic power machine, larger energy resource consumption will be brought, increase use cost.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of rational in infrastructure, compact, easy to use, reliable, the mix and blend of various mixed material can be applicable to, reduce use cost, improve the Spiral internal mixer of service life of equipment.
The object of the invention is to have come by following technical solution, it includes a frame, frame is mounted with the machine barrel of band feed hopper, and machine barrel is coated with the heat preserving casing of band heater; Axial arranged in machine barrel have at least one screw rod, and the feed end of screw rod is connected with motor by one speed reducer assembly, and the other end of screw rod extends to the outlet end of machine barrel, and the outlet end of described machine barrel is provided with the head with cutter assembly.
Described machine barrel is horizontally-arranged in frame, and described heat preserving casing is made up of shell body and built-in insulation material, the outer wall being close to machine barrel is provided with the heater of electric heater composition; The feed hopper side of machine barrel is provided with reducer assemblies that be connected with screw rod, that be made up of decelerator and torque protection device, and this reducer assemblies is connected with motor by pulley transmission mechanism.
Described torque protection device comprises the main shaft and interior axle that are mutually linked in and also can mutually rotate together, described main shaft and interior axle are fixedly connected with adjacent spindle flange dish and interior shaft flange dish each via key at same side, and arrange the shear pin both combined between described spindle flange dish and interior shaft flange dish; The main shaft be nested with outside interior axle is connected with decelerator by gear wheel, and described interior axle is connected with screw rod.
Decelerator of the present invention comprise one with belt pulley coaxial, the shaft gear that is engaged with idler gear, the countershaft-gear coaxial with this idler gear engages with the gear wheel on main shaft; Described belt pulley is connected with the motor pulley that motor shaft is connected by belt, and the pulley transmission mechanism described in forming.
The invention belongs to and improve the one of prior art, it has rational in infrastructure, compact, easy to use, reliable, can be applicable to the mix and blend of various mixed material, reduces use cost, can improve the features such as service life of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of torque protection device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the present invention includes a frame 1, frame 1 is mounted with the machine barrel 3 of band feed hopper 2, and machine barrel 3 is coated with the heat preserving casing of band heater 4; Axial arranged in machine barrel 3 have at least one screw rod 5, and the feed end of screw rod 5 is connected with motor 6 by one speed reducer assembly, and the other end of screw rod 5 extends to the outlet end of machine barrel 3, and the outlet end of described machine barrel 3 is provided with the head 7 with cutter assembly.
Shown in figure, described machine barrel 3 is horizontally-arranged in frame 1, and described heat preserving casing is made up of shell body 8 and built-in insulation material 9, and described insulation material 9 comprises asbestos etc.; The outer wall being close to machine barrel 3 is provided with the heater 4 of electric heater composition; Feed hopper 2 side of machine barrel 3 is provided with reducer assemblies 17 that be connected with screw rod 5, that be made up of decelerator and torque protection device, and this reducer assemblies is connected with motor 6 by pulley transmission mechanism 10.
Shown in Fig. 2, described torque protection device comprises and to be mutually linked in together and can the main shaft 11 of separate rotation and interior axle 12, described main shaft 11 and interior axle 12 are fixedly connected with adjacent spindle flange dish 13 and interior shaft flange dish 14 each via key at same side, and between described spindle flange dish 13 and interior shaft flange dish 14, arrange the shear pin 15 both combined; The main shaft 11 be nested with outside interior axle 12 is connected with decelerator by gear wheel 16, and described interior axle 12 is connected with screw rod 5.
Decelerator of the present invention can be existing arbitrary decelerator meeting application claims, or the deceleration device of following structure composition; It comprises one with belt pulley coaxial, the shaft gear that is engaged with idler gear, the countershaft-gear coaxial with this idler gear engages with the gear wheel 16 on main shaft 11; Described belt pulley is connected with the motor pulley that motor shaft is connected by belt, and the pulley transmission mechanism 10 described in forming,
The course of work of torque protection device of the present invention is: motor 6 is connected with decelerator by pulley transmission mechanism 10, and be connected with torque protection device by described decelerator, and by described torque protection device by power transmission to screw rod, the screw rod making to be placed in machine barrel rotates; When screw rod operation torque is greater than design work moment of torsion; shear pin automatically ruptures under two ring flange twisting forces, and interior axle is separated with main shaft, and main shaft still can rotate; and axle loses power and stops operating in being connected together with screw rod, thus reach the effect of protection screw rod.
