Abstract
The utility model provides a two-stage feeding device, comprising a first-stage feeding unit and a second-stage feeding unit. A discharge port of the first-stage feeding unit is connected with a material inlet of the second-stage feeding unit through a feeding pipeline. The two-stage feeding device solves the problem of relative great fluctuation of discharge speed of a conventional feeding device, and is characterized by reasonable design, simple structure, and uniform feeding.
Description
Technical field
This novel field of mechanical technique that relates to especially relates to a kind of unloader.
Background technology
Along with improvement of Manufacturing Technology and development, food industry, packaging industry, pharmaceuticals industry and electrical apparatus industry constantly propose new requirement to unloader.Unloader usually and extruder be used, prepare the material of certain degree of uniformity and thickness.
Existing unloader can be divided into single screw rod unloader and twin screw unloader by screw form, all rotates through the motor-driven screw rod, when screw rod rotates, promotes material and is flowed out by discharging opening, gets into the subsequent production flow process.Chinese patent ZL200420019433.3 discloses a kind of unloader, comprises base, material storing box, motor, screw rod, and said screw rod links to each other with motor, and the rotation through motor drives worm screw the material in the material storing box is released.
There is following defective in existing unloader: because the inventory in the material storing box changes fluctuation greatly; Cause the discharging speed fluctuation bigger; Thereby cause the material pressure of sensing with unloader discharging opening bonded assembly extruder unstable; Cause the degree of uniformity and the thickness fluctuation of product in the production process bigger, restive, the qualification rate of product is lower.
Summary of the invention
This later-model purpose is to the problems referred to above, provides a kind of reasonable in design, simple in structure, the uniform two-stage unloader of blanking.
For achieving the above object this novel following technical proposal that adopted:
This is novel creatively to provide a kind of two-stage unloader, comprises first order unloader, second stage unloader, and the discharging opening of said first order unloader is connected through the inlet point of blanking pipeline with second stage unloader.
This later-model improvement is: said second stage unloader comprises material storing box, twin screw; Said material storing box lower, transverse has the mounting hole that runs through two relative side plates of material storing box; Twin screw is transverse in the mounting hole; One end of twin screw is connected with the slip electric motor that drives twin screw, and the other end of twin screw is communicated with the discharging opening of second stage unloader through the twin screw passage.
This later-model further improvement is: the change speed gear box II that is provided with adjustable-speed between said slip electric motor and the twin screw.
This later-model further improvement is: said first order unloader is the twin screw unloader, comprises the motor of twin screw, driving twin screw, is provided with the change speed gear box I of adjustable-speed between twin screw and the motor.
This later-model further improvement is: the speed of said change speed gear box I is less than the change speed gear box II.
Compared with prior art, this later-model advantage is:
After this later-model material is extruded from first order unloader, through the second time unloader carry once more, can avoid the blanking fluctuation of first order unloader, thereby material is seen off equably.Because the buffer action of having passed through first order unloader; There is not buildup in the unloader of the second stage; And then the fuselage pressure with second stage unloader bonded assembly extruder is fluctuateed all the time in very little scope; And then the thickness of extruded product, degree of uniformity are in the up-to-standard number range all the time, thus ensured product design, improved production efficiency.
This later-model two-stage unloader is simple in structure, easy to assembly, utilizes existing unloader through the blanking plumbing connection, can realize even blanking, has good economic benefit.Adopt the twin screw pusher, dynamics is even, is difficult for sizing, can effectively ensure the at the uniform velocity feed of extruder.Adopt the twin screw pusher, make mass transport more even.Adopt the type of drive of slip electric motor and change speed gear box, can adjust the rotating speed and the thrust of twin screw easily, thereby can regulate blanking velocity according to actual needs.The speed of change speed gear box I can prevent to produce buildup in the secondary unloader less than the change speed gear box II, avoids accumulation of material to cause blanking inhomogeneous.
Description of drawings
Fig. 1 is this later-model structural representation.
Among the figure, 1, first order unloader; 2, twin screw; 3, material storing box; 4, extruder; 5, blanking pipeline; 6, slip electric motor; 7, change speed gear box I; 8, change speed gear box II.
The specific embodiment
Specific embodiment described herein only is that the utility model spirit is made casehistory.This novel person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from this later-model spirit or surmount the defined scope of appended claims.
As shown in Figure 1, the two-stage unloader of present embodiment comprises first order unloader 1, second stage unloader.First order unloader comprises twin screw, drives the motor of twin screw.Be provided with change speed gear box I 7 between twin screw and the motor.The discharging opening of first order unloader is connected through the inlet point of blanking pipeline 5 with second stage unloader.Said second stage unloader comprises material storing box 3, twin screw 2; Said material storing box lower, transverse has the mounting hole that runs through two relative side plates of material storing box; Twin screw is transverse in the mounting hole; One end of twin screw is that the slip electric motor 6 of 2.2kw is connected through change speed gear box II 8 and power, and the other end of twin screw is communicated with the discharging opening of second stage unloader through the twin screw passage.The discharging opening of second stage unloader is connected with extruder 4.
During use, the speed that makes the change speed gear box I drops into first order unloader less than the change speed gear box II with material; And through the first season unloader get into the material storing box of second stage unloader through the blanking pipeline; Under the promotion of twin screw, get into extruder, obtain the uniform product of thickness.
