Description

A kind of small-sized lateral feeding machine

Technical field

The utility model relates to extruder technology field, the small-sized lateral feeding machine of especially a kind of experiment.

Background technique

Added material is added from main feed opening in conventional extruder, on the one hand since multiple material heap density is different, especially It is easy layering when adding powder, the component of finished product will be caused uneven, on the other hand, since added material hardness is mostly relatively high, In solid-state, will not be plasticized, from the solid conveying section of machine barrel be added will caused by feeding section screw rod and machine barrel abrasion.But If packing material is added from material melts section, filler material one enters host i.e. by molten by the way of laterally feeding Material package mixes, and avoids the abrasion of screw rod and machine barrel, and energy dissipation caused by more reducing because of friction effectively improves Yield and production efficiency, reduce production cost.

Utility model content

The purpose of the utility model is to provide a kind of experiments compact-sized, at low cost and stable drive laterally to be fed with small-sized Material machine.

The technical solution adopted in the utility model is:

A kind of small-sized lateral feeding machine, including rack, are equipped with multiple idler wheels below rack, tooth connection roller box above rack, The right side of the gear-box connects motor, and specific connection type is as follows: the input shaft in gear-box is connected to motor, on input shaft Be cased with No.1 gear wheel and No. two gear wheels, No.1 gear wheel is engaged with the No.1 pinion gear on output shaft, No. two gear wheels with No. two pinion gears engagement on another output shaft, No.1 pinion gear and No. two pinion gears do not engage mutually.

Two output shaft connecting screws in the gear-box, gear-box left side connector drum, inner barrel are hollow, packets It wraps up in screw rod and is equipped with opening connection lower hopper there are gap, above cylinder, be fixedly connected with out on the left of cylinder with screw or bolt Barrel, the length of screw rod are greater than the summation of cylinder and discharge barrel length.

Preferably, the overall structure of the cylinder is concave, and the right and left of cylinder is slightly above intermediate, and in left and right The protrusion on both sides is arranged with through-hole.

The beneficial effects of the utility model are:

(1) gear-box uses helical gear, is a kind of progressively engaged process between the helical gear gear teeth, the stress on the gear teeth It is gradually ascending, then descending；Therefore helical gear engagement is more steady, and impact and noise are small, is suitable for high speed, big function Rate transmission.Under equal conditions, helical gear engagement process is longer than spur gear, i.e., registration is larger, and this reduces each pair of teeth The load of wheel extends the service life of gear to improve the bearing capacity of gear, and makes stable drive.

(2) the protrusion part of cylinder the right and left and through-hole are used for tooth connection roller box and discharge barrel, discharge barrel and cylinder Detachable connection method keeps the utility model compact-sized, at low cost.
