Description
Technical field
The present invention relates to a kind of roller regulating device, this roller regulating device is used in the claim 1 this extruder as described in the preamble.
Background technology
In extruder, need the distance between dancer rools and mould usually, and in operating process, carry out possible adjusting, so that optimize pelletization.The well known device that is used to carry out this adjusting is realized this adjusting by the hydraulic cylinder that utilization is directly connected on the roll shaft, described in U.S. Pat 4861529, perhaps via placing extruder axial location place and realizing this adjusting, described in EP238147 or EP594278 via the rotatable shaft that cam disc or geared system are connected on the roll shaft.
Summary of the invention
The purpose of this invention is to provide a kind of above-mentioned roller regulating device, utilize this roller regulating device, can avoid mechanical organ with sensitivity to place near the roller under the corrosive atmosphere condition, and can realize this purpose with described roller regulating device, the described feature of characteristic that is also included within claim 1 according to described roller regulating device of the present invention.Utilize this device, only will place as the simple and mechanical element of connecting rod and Connection Element and so near the roller, and can move these elements by manual adjustments or by means of suitable actuating device, wherein, described actuating device places outside the corrosive atmosphere near the roller of extruder.Disclose the preferred embodiment of roller regulating device in the dependent claims, from specification described in detail below, can obviously find out its advantage.
Description of drawings
In the detailed part of this specification, the present invention will narrate in more detail with reference to the one exemplary embodiment of roller regulating device, and will be shown in the drawings according to described roller regulating device of the present invention, wherein:
Fig. 1 illustrates the cutaway view that the partial cut of the roller regulating device in the extruder that comprises two rollers slices off;
Fig. 2 illustrates the device of seeing from the end of Fig. 1;
Fig. 3 illustrates the viewgraph of cross-section of the device of the Fig. 1 and 2 that is seen along the III-III line of Fig. 2; And
Figure 4 and 5 are schematically illustrated to comprise related device in the extruder of three rollers.
The specific embodiment
Device shown in Fig. 1 comprises the major part of the extruder that is used to pulverize various food.Extruder comprises and has radially the cylindrical die of extruding passage (2) and a plurality of roller (1) that extends, and is 2 at the number of roller described in Fig. 1-3.Roller (1) is mounted for rotation about their axes and cooperates with cylindrical die (2), thereby pending material is pressed through the passage of extruding in the mold wall.Be used for that the device driven (not shown) orders about that cylindrical die (2) rotates and the axle that orders about each roller (1) relative to each other around the rotation of the axis of cylindrical die (2).Roller (1) is installed on the back shaft (3), described back shaft (3) is eccentric motion (journalled) in the hole of the back support flange (4) of roller and front roller support plate (5), and the Connection Element that is positioned between each roller (1) interconnects described back support flange (4) and front roller support plate (5).The eccentric motion of axle (3) makes by the rotation of the axle (3) of this eccentric motion, can obtain roller (1) the radial position adjusting of cylindrical die (2) relatively.For the rotation of axle (3) that eccentric motion is provided is regulated, adjutage (6) is fixedly secured to the end of the axle (3) of eccentric motion, and described adjutage (6) is connected on the axially movable Connection Element (8) by the articulated linkage (7) of thread form, and described thread can carry out the adjusting at zero point in the position of cylindrical die (2) by pair roller (1) relatively.Connection Element (8) is connected on the bar (9), described bar (9) and cylindrical die (2) coaxial line, and extend to the extruder outside, it is connected on the suitable actuating device in this extruder outside.
Back shaft (3) by maintenance roller (1) is static, and rotational circle cylindricality mould (2), otherwise or keep cylindrical die (2) static, and the back shaft of rotation roller (1), can obtain the relative rotation between roller (1) and cylindrical die (2), in this case, will have to provide a rotation to connect between actuator and Connection Element (8), this rotation connects the actuator end that may be positioned at bar (9).
As seeing from Fig. 3, moving axially of Connection Element (8) makes the axle (3) of eccentric motion also rotate mobile, this just causes roller (1) to move towards and away from cylindrical die (2), whereby, can come distance between dancer rools (1) and cylindrical die (2) according to the required function of extruder.Thread (7) can pair roller (1) dead-center position carry out possible adjusting, and this adjusting position can be fixed by means of the nut that is installed on the thread (7).The form that is connected the ball-and-socket joint (11,12) that is made as respectively on the bolt that is connected to thread (10) between thread and Connection Element and adjutage, thus being articulated and connected between adjutage (6) and the Connection Element (8) is provided.
Preferably, can make described mechanism form required size and adjusted by this way, promptly near as far as possible apart from cylindrical die (2) at roller (1), but between roller (1) and the cylindrical die (2) during still without any Metal Contact, the axis normal of thread (7) and cylindrical die (2).This just at roller (1) when the cylindrical die (2), maximum power transmission is arranged between the position of actuator and roller (1), and at roller (1) when the cylindrical die (2), but the distance between pair roller (1) and the cylindrical die (2) is carried out trickleer adjusting.
Near under the situation of cylindrical die (2), make the close summit of off-centre of the back shaft (3) of eccentric motion at roller (1), this has just further supported last feature.
Above narrating the preferred embodiments of the present invention, but can predict various optimizations under the situation that does not depart from following claim of the present invention, this species diversity comprises the roller (1) that another kind of number is provided, and the preferred number of roller is 2 or 3.And, be connected to the suitable actuator that actuator on the bar (9) can be set as the linear actuators of hydraulic pressure or air rammer air cylinder device, leading screw pattern or be used for any other pattern of this purpose.The manual adjustments of the position of bar (9) also can be predicted.And, can change the position of actuator, as change it to axle position in (4), bar (9) can be the piston rod of piston cylinder device in this case, perhaps in the position of axle (4) opposite side.
