Description
Technical field
The present invention relates to a kind of device that is used for opening and closing the kneader loam cake.
Background technology
Loam cake adopts rotational structure mostly in the kneader when opening and closing at present, promptly the sidepiece in the kneading chamber is provided with frame, be provided with rotating shaft in the frame, be connected with turning arm on the rotating shaft, the other end and the loam cake of turning arm fix, also be provided with cylinder on the frame, the motion bar of cylinder is connected with turning arm.When loam cake need be combined on the kneading chamber, the motion bar of cylinder stretched out, and making turning arm is that the center of circle turns clockwise with the rotating shaft, and loam cake is transferred closed with the synchronous dextrorotation of turning arm.When loam cake need be opened, the motion bar of cylinder withdrawal, making turning arm is that the center of circle is rotated counterclockwise with the rotating shaft, loam cake is rotated counterclockwise synchronously with turning arm and opens.Shortcoming is: because can there be certain error in the rotation mode of frame for movement, loam cake is when rotating closed, the lower edge of loam cake can contact with the kneading chamber at first, this moment loam cake other parts as yet fully and the kneading chamber reach closure state, the motion bar that is cylinder is still stretching out, thereby cause the lower edge of loam cake and the contact site of kneading chamber can be subjected to bigger extruding force, usually the tetrafluoroethene bar can be set with the sealing between realization and the kneading chamber in the lower surface of loam cake, the tetrafluoroethene bar sustains damage under bigger extruding force easily, thereby influences the sealing between loam cake and the kneading chamber; Equally, loam cake is when rotarily opening, and an end of loam cake breaks away from the kneading chamber at first, and the other end of loam cake---be the lower edge of loam cake when closure, then can be because of being subjected to bigger extruding force, thus cause the tetrafluoroethene bar to sustain damage, influence the sealing between loam cake and the kneading chamber.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of when opening and closing loam cake, can make the contact site of the lower edge of loam cake and kneading chamber can not be subjected to the headstock gear of loam cake in the kneader of bigger extruding force.
For addressing the above problem, the technical solution used in the present invention is: the headstock gear of loam cake in the kneader, comprise the frame that is arranged on kneading chamber sidepiece, be provided with rotating shaft in the frame, be connected with turning arm on the rotating shaft, also be provided with cylinder on the frame, the motion bar of cylinder is connected with turning arm, be provided with regulating shaft in the other end of turning arm, loam cake flexibly connects with turning arm mutually by regulating shaft.
Be connected with screw mandrel on the described turning arm, the two ends of screw mandrel are respectively arranged with top nut and lower nut, and top nut and turning arm fix, and lower nut and loam cake fix, and the axis of screw mandrel and the lower surface of loam cake are perpendicular.
The invention has the beneficial effects as follows: the headstock gear of loam cake in the above-mentioned kneader, simple in structure, easy to use.Make improvements slightly on present structure, make loam cake when opening and closing, the lower edge of loam cake is under the situation that is subjected to bigger extruding force, loam cake can be made adjusting automatically, make loam cake stressed evenly, thereby avoided the tetrafluoroethene bar to sustain damage, guarantee the sealing between loam cake and the kneading chamber.

Fig. 2 is the structural representation that loam cake is in closure state in the headstock gear of loam cake in the kneader of the present invention;
Among the figure: 1, kneading chamber, 2, frame, 3, rotating shaft, 4, turning arm, 5, cylinder, 6, regulating shaft, 7, loam cake, 8, screw mandrel, 9, top nut, 10, lower nut.
The specific embodiment
Be described in further detail below by the headstock gear of specific embodiment loam cake in the kneader of the present invention.
As shown in Figure 1 and Figure 2, the headstock gear of loam cake in the kneader, comprise the frame 2 that is arranged on kneading chamber 1 sidepiece, be provided with rotating shaft 3 in the frame 2, be connected with turning arm 4 on the rotating shaft 3, also be provided with cylinder 5 on the frame 2, the motion bar of cylinder 5 is connected with turning arm 4, be provided with regulating shaft 6 in the other end of turning arm 4, loam cake 7 flexibly connects with turning arm 4 mutually by regulating shaft 6.Be connected with screw mandrel 8 on the described turning arm 4, the two ends of screw mandrel 8 are respectively arranged with top nut 9 and lower nut 10, and top nut 9 fixes with turning arm 4, and lower nut 10 fixes with loam cake 7, and the lower surface of the axis of screw mandrel 8 and loam cake 7 is perpendicular.
Operation principle of the present invention is: when loam cake 7 need be combined on the kneading chamber 1, the motion bar of cylinder 5 stretches out, making turning arm 4 is that the center of circle turns clockwise with rotating shaft 3, loam cake 7 is transferred closed with turning arm 4 synchronous dextrorotations, when the lower edge of loam cake 7 contacts with kneading chamber 1, the lower edge of loam cake 7 and the contact site of kneading chamber 1 are subjected to bigger extruding force, this moment, loam cake 7 was that the center of circle is rotated counterclockwise accordingly with regulating shaft 6 under the effect of extruding force, and screw mandrel 8 moves upward along with being rotated counterclockwise of loam cake 7, the upper end of screw mandrel 8 turn in top nut 9 when screw mandrel 8 moves upward, the turn in lower nut 10 of the lower end of screw mandrel 8, wherein because there is certain frictional force during turn in screw mandrel 8 in top nut 9 and lower nut 10, the effect of screw mandrel 8 is to rely on above-mentioned frictional force and the inertia force that produces when weakening loam cake 7 and being rotated counterclockwise, prevents that loam cake 7 from bumping with turning arm 4 because of inertia force and impaired when being rotated counterclockwise.When loam cake 7 needs to open, the motion bar withdrawal of cylinder 5, making turning arm 4 is that the center of circle is rotated counterclockwise with rotating shaft 3, loam cake 7 is rotated counterclockwise synchronously with turning arm 4 and opens, when an end of loam cake 7 breaks away from kneading chamber 1 at first, and the other end of loam cake 7---be that the lower edge of loam cake 7 when closure is when being subjected to bigger extruding force, loam cake 7 is that the center of circle turns clockwise accordingly with regulating shaft 6 under the effect of extruding force, and screw mandrel 8 is along with the dextrorotation of loam cake 7 then move downward, the upper end of screw mandrel 8 turn in top nut 9 when screw mandrel 8 moves downward, the turn in lower nut 10 of the lower end of screw mandrel 8, wherein because there is certain frictional force during turn in screw mandrel 8 in top nut 9 and lower nut 10, the effect of screw mandrel 8 is to rely on above-mentioned frictional force and the inertia force that produces when weakening loam cake 7 and turning clockwise, prevents that loam cake 7 from bumping with turning arm 4 because of inertia force and impaired when turning clockwise.
The invention has the beneficial effects as follows: the headstock gear of loam cake in the above-mentioned kneader, simple in structure, easy to use.Make improvements slightly on present structure, make loam cake 7 when opening and closing, the lower edge of loam cake 7 is under the situation that is subjected to bigger extruding force, loam cake 7 can be made adjusting automatically, make loam cake 7 stressed even, thereby avoided the tetrafluoroethene bar to sustain damage, guarantee the sealing between loam cake 7 and the kneading chamber 1.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
