A kind of adjustable material outlet device
Technical field
The utility model relates to extruding-desiccation machine technical field, particularly relates to a kind of adjustable material outlet device.
Background technology
Original electronic rotation template head pressure regulating device utilizes motor rotary worm to promote turbine and runs the rotation of drive rotary template up and down, the circular hole of the material discharging round hole on rotary template and extruder head template is misplaced, thus reduce material outlet sectional area, improve the pressure of outlet material.When this head pressure regulating device is just installed, when the material in extruder is few, pressure regulating device can be used for the pressure size of regulating frame head material.When in extruder barrel, material is full of, the driving force of worm and gear is not enough to driven rotary template and rotates, and head regulatory function lost efficacy.Therefore, this head pressure regulating device just cannot have been used after operation very short time again.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of adjustable material outlet device that effectively can regulate discharge area size.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of adjustable material outlet device, comprise rotary template, described rotary template front is provided with die template, described rotary template is provided with multiple through hole, described die template is provided with the discharge opening corresponding with described through hole, described rotary template side is provided with connecting plate, this connecting plate one end is with arc gear ring, described arc gear ring side is connected with little gear ring, be meshed with described little gear ring outside described arc gear ring, described little gear ring center runs through pinion shaft, external splines is provided with outside described pinion shaft, the internal spline matched with described external splines is provided with inside described little gear ring.
Further, be provided with pinion seat before described pinion shaft, this pinion seat plays position-limiting action to pinion shaft, and prevents little gear ring from deviating from.
Further, described pinion seat one end is provided with perpendicular lattice framing, and these perpendicular lattice framing two ends are connected with horizontal lattice framing.
Further, described rotary template front is provided with cylindrical shell, and this cylindrical shell side is provided with circular arc block.
Further, the described arc gear ring anglec of rotation is ± 7-10 °.
Compared with prior art, the utility model has the advantage of: the utility model rotates by the mechanism transmitting power being selected gear drive to promote rotary template, cause the discharge opening of rotary template through hole and die template to misplace, thus impel outlet material to increase pressure; And gear drive reliability is high, operator can the material pressure of regulating frame head easily, mixes up rear durable in use, can not change; Simultaneously simpler than employing hydraulic circuit, clean, the utility model is reasonable in design, can be applicable in similar mechanism.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1 and Figure 2, a kind of adjustable material outlet device, comprise rotary template 2, described rotary template 2 front is provided with die template 3, described rotary template 2 is provided with through hole 11, and described die template 3 is provided with the discharge opening 13 corresponding with described through hole 11, and described rotary template 2 side is provided with connecting plate 5, this connecting plate 5 one end is provided with arc gear ring 6, is meshed outside described arc gear ring 6 with little gear ring 7, this little gear ring 7 center is run through has pinion shaft 8 with external splines 14, the internal spline 15 matched with described external splines 14 is provided with inside described little gear ring 7, described pinion shaft 8 is placed in pinion seat 9 mixing little gear ring 7, this pinion seat 9 pairs of pinion shafts 8 position-limiting actions, and prevent little gear ring 7 from deviating from, described rotary template 2 rear is provided with cylindrical shell 1, this cylindrical shell 1 is provided with circular arc block 4 near the position up and down of head, described pinion seat 9 is connected on perpendicular lattice framing 10, these perpendicular lattice framing 10 two ends are connected with horizontal lattice framing 12, this horizontal lattice framing 12 is connected on the circular arc block 4 of the forward end of cylindrical shell 1 upper and lower position setting, described arc gear ring 6 anglec of rotation is ± 7-10 °.
Operation principle briefly explains:
The anglec of rotation of pinion shaft 8 is regulated with spanner, little gear ring 7 is driven, and then control the rotation amount of arc gear ring 6 and turn over an angle by connecting plate 5 driven rotary template 2, the through hole 11 on rotary template 2 is made to miss a position with the discharge opening 13 of die template 3, thus reduce material outlet sectional area, increase the outlet pressure of material.
Compared with prior art, the utility model has the advantage of: the utility model rotates by selecting gear drive to transmit powered rotary template, the discharge opening of rotary template through hole and die template is caused to misplace, thus impel outlet material to increase pressure, and gear drive reliability is high, operator can the material pressure of regulating frame head easily, mixes up rear durable in use, can not change; Regulate outlet simple, clean than employing hydraulic circuit simultaneously.The utility model is reasonable in design, can large-scale promotion.
