A kind of feed mechanism of Granulation Equipments

Technical field

The utility model relates to a kind of Granulation Equipments, particularly relates to the feed mechanism in the Granulation Equipments, belongs to mechanical field.

Background technology

Most polymers needs multiple plastic raw materials is stirred by mixer before manufacturing, pours in the barrel of extruder again, various raw materials carry out fusion in extruder, extrude by screw rod, the grain-cutter with rotation at a high speed is cut into pellet then, because the pellet temperature height that has just cut out, viscosity is big, therefore, it is cooled off by the air-cooled mode of multiple tracks, treat its temperature step-down, after the reduced viscosity, utilize vibration screening mechanism to filter out the qualified particle of cooling again.

But the general mode that adopts artificial cat ladder to fall of the multiple mixed plastic raw material after stirring is poured in the barrel of extruder, and the position of barrel is higher relatively, and not only labour intensity is big, and wastes time and energy, and also has potential safety hazard.

Summary of the invention

The utility model provides a kind of feed mechanism that mixed plastic raw material automatic transport can be arrived the Granulation Equipments in the barrel of extruder.

The purpose of this utility model can realize by following technical proposal: a kind of feed mechanism of Granulation Equipments, comprise frame and the hopper of being located on the frame, it is characterized in that, described hopper links to each other with the lowering or hoisting gear that its relative frame is moved up and down, and the batch turning structure that the raw material in the hopper is poured out is also established on the top of described lowering or hoisting gear downwards.

The feed mechanism of this Granulation Equipments is located between mixer and the extruder, when this hopper drops to the bottom (being positioned at the discharging opening place of mixer) of lowering or hoisting gear, can feed, the mixed plastic raw material that stirs is poured in the hopper by the discharging opening of mixer, this hopper is thus lifted to the top (being positioned at the barrel top of extruder) of lowering or hoisting gear then, under the effect of batch turning structure, make raw material in the hopper downwards to the barrel of extruder, so far finish the process of automatic transport.

In the feed mechanism of above-mentioned Granulation Equipments, described lowering or hoisting gear comprises having a down dip is located at ringwise chain on the frame, and this chain can be done two-way reciprocating motion, and described hopper is connected mutually with described chain.Because hopper directly is connected mutually with chain, so chain can't do gyration, be thus lifted to the upper end of chain when hopper after, need be back to the lower end of chain by former road.

In the feed mechanism of above-mentioned Granulation Equipments, the bottom of described hopper is fixed on the described chain, and also is provided with guide frame between described hopper and the described chain.Chain is fixedly arranged on the bottom of hopper, makes compact conformation, and guide frame helps making hopper to move back and forth reposefully.

In the feed mechanism of above-mentioned Granulation Equipments, described guide frame is that the both sides corresponding to hopper are installed with the guide rail that is parallel to chain respectively on frame, be installed with connecting rod between described hopper and the described chain, the two ends of this connecting rod are installed with the pulley that matches with corresponding guide rail respectively.The base abuts of pulley and can move along guide rail on guide rail.

In the feed mechanism of above-mentioned Granulation Equipments, the inboard of described two guide rails has chute respectively, and described two pulleys are located in the corresponding chute.Pulley is located in the chute of guide rail, is made and slide reliably, compact conformation, volume is little.

In the feed mechanism of above-mentioned Granulation Equipments, described batch turning structure is to have reclinate extension in the upper end of described chain, and described hopper is the dustpan shape, and its front upper part has inlet orifice.When hopper was thus lifted to the extension of chain, the front upper part of hopper was downward-sloping naturally, and the raw material in it is poured out downwards automatically.

In the feed mechanism of above-mentioned Granulation Equipments, the angle of bend between the upper end of described extension and its lower end is less than 90 °.Helping snap back resets.

In the feed mechanism of above-mentioned Granulation Equipments, described chain is driven by a clockwise and anticlockwise motor, and also is provided with decelerator between described clockwise and anticlockwise motor and described chain.Clockwise and anticlockwise motor is used to control the traffic direction of chain; Because the rotating speed of clockwise and anticlockwise motor is higher, can obtain required speed by decelerator is set.

In the feed mechanism of above-mentioned Granulation Equipments, described clockwise and anticlockwise motor links to each other with input shaft of speed reducer by driving-belt, and the output shaft of described decelerator drives a power transmission shaft by driving chain, and described chain is driven by this power transmission shaft.

Compared with prior art, the feed mechanism of this Granulation Equipments can be realized automatic charging and batch turning, thereby replaces traditional manual operations, can reduce labour intensity greatly, increases work efficiency, and makes conveying safer, easy.
