Abstract

The utility model discloses a cutting mechanism of a spiral extruder, which belongs to the field of feed material processing devices. The cutting mechanism of the spiral extruder comprises a motor; the motor is connected with one end of a connecting rod; an L-shaped pore is formed at the other end of the connecting rod; and a metal wire passing through the pore is arranged inside the pore, and is fixed through a screw. The cutting mechanism of the spiral extruder adopts the structure that the metal wire rotating at a high speed is used as a cutter for cutting materials extruded from the extruder; and the metal wire rotating at a high speed is good at the wear resisting property when used as a cutter, and is not required to be replace regularly, therefore, time is saved, and work efficiency is improved. The utility model can be applied to various spiral extruders.

Description

A kind of screw extruder cutting mechanism
Technical field
The utility model relates to a kind of feed material processing unit (plant), particularly a kind of screw extruder.
Background technology
Existing screw extruder comprises single-screw extrusion machine, twin (double) screw extruder and multiscrew extrusion machine, and its used granulating mechanism is generally the rigidity cutter mechanism, comprises the blade, the pressing plate that are fixed on the knife rest, and knife rest and motor connecting rod are fixed together; The driven by motor knife rest is done rotation at a high speed like this, blade cuts the strip-shaped materials of extruding from extruder, described blade rotary end surface is parallel with the template end face, and the rotary speed by adjusting cutting tool and the linear velocity of extruded product obtain the length of required product.Its weak point is: because the mismachining tolerance of blade, hardness, intensity, thrust etc. there are differences, the degree of wear differs during cutting, cause cutting out the different in size of particle, influenced the outward appearance of product, thereby need make regular check on the wear condition of blade, position, the replacing of adjusting blade according to damage situations damage blade etc.; This process is lost time, and influences operating efficiency, increases production cost.
The utility model content
The purpose of this utility model provides a kind of screw extruder cutting mechanism, and it is not easy to wear that the wire of high speed rotation is made cutting knife, makes its cutting evenly, saves time, thereby has improved operating efficiency.
The purpose of this utility model is achieved in that a kind of screw extruder cutting mechanism, comprise motor, described motor links to each other with connecting rod one end, and the described connecting rod other end has L type pore, be provided with the wire that passes pore in the described pore, wire is fixed through screw.
During the utility model work, the motor high speed rotating drives the wire high speed rotating that is fixed on the connecting rod end, the material that the wire of high speed rotating is extruded as cutting knife cutting extruder, compared with prior art, the beneficial effects of the utility model are: the wire of rotation is not easy to wear as cutting knife at a high speed, do not need often maintenance to change, thereby saved the time, improved operating efficiency; The cutting material is evenly attractive in appearance, the length unanimity.
In order to improve cutting frequency wiry, improve stock-removing efficiency, described L type pore offers two along the circumferential symmetry of connecting rod, is provided with the wire through screw in compression in each pore.
Centrifugal force when rotating in order to increase wire increases wire cutting force, further improves stock-removing efficiency, and described wire cutting end part is connected with balancing weight.
In order to control rotary speed wiry, thus the size of control pelletizing, and described motor is a variable-frequency motor.
In order further to improve stock-removing efficiency wiry, described wire is a steel wire.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged drawing of A among Fig. 1.
Wherein, 1 balancing weight, 2 wires, 3L type pore, 4 screws, 5 connecting rods, 6 variable-frequency motors.
The specific embodiment
As shown in Figure 1, a kind of screw extruder cutting mechanism, comprise variable-frequency motor 6, variable-frequency motor 6 links to each other with connecting rod 5 one ends, described connecting rod 5 other ends have the L type pore 3 of two symmetries, are provided with the wire 2 that passes pore in the described L type pore 3, and wire 2 is fixed through screw 4, wire 2 cutting end parts are connected with balancing weight 1, and wire 2 is a steel wire.
During work, variable-frequency motor 6 high speed rotating drive wire 2 high speed rotating that are fixed on connecting rod 5 ends, the material that the wire 2 of high speed rotating is extruded as cutting knife cutting extruder, the wire 2 of rotation is not easy to wear as cutting knife at a high speed, do not need often maintenance to change, thereby saved the time, improved operating efficiency; The cutting material is evenly attractive in appearance, the length unanimity; Centrifugal force when the balancing weight 1 that is arranged on wire 2 cutting end parts has increased rotation, thereby increased the cutting force of wire 2, further increase work efficiency, select for use variable-frequency motor 6 can reach the purpose of control product length size by the rotating speed of wire 2 on the control connection bar 5.
The utility model is not limited to the foregoing description; as connecting rod 5 other ends can evenly be provided with a plurality of L type pores 3; be provided with wire 2 in each pore; and wire 2 also can be a molybdenum filament; above-mentioned situation is all in the utility model protection domain; those skilled in the art can also be on the basis departing from above-mentioned technological thought not; just can more be out of shape and revise technique scheme without performing creative labour, these distortion and revising all fall in the protection domain of the present utility model.
