Abstract
The utility model discloses an adopt crank throw formula locking structure's banbury mixer unloads bin gate locking device, it includes the base, and the cylinder body of locking hydro -cylinder is connected with the base through the round pin axle, and the one end of characterized by initiative connecting rod, passive connecting rod is connected with the base through the round pin axle respectively, and the other end is connected through round pin axle and locking base, down locking fill up and install on locking the base, the piston rod of locking the hydro -cylinder passes through to sell spool and takes the initiative the connecting rod to be connected, the line of centres of four round pin axles that initiative connecting rod, passive connecting rod and base, locking base are connected are flat shape quadrangle, and the contained angle of contact surface and the horizontal plane of contained angle and the last locking pad of the contact surface that fills up of locking and horizontal plane is equal down, the utility model discloses a crank -mechanism is parallelogram mechanism, makes locking down fill up and changes the face contact with the contact of last locking pads into by the line contact, has improved the bearing capacity of upper and lower locking pads greatly, has reduced the wearing and tearing of upper and lower locking pad, and then has reduced locking device and move excessive risk, has improved the stable of locking device and economic nature.
Description
Technical field
The utility model relates to a kind of banbury, specifically a kind of discharge door of banbury mixer locking device, particularly relates to a kind of discharge door of banbury mixer locking device adopting curvature crank type locking mechanism.
Background technology
Closed refining glue (moulding) machine is called for short banbury, and it is the visual plant of rubber plastic processing.Be mainly used in the mixing of rubber or plastics and compounding ingredient.Banbury adopts intermittent cyclic mode to carry out milling work, and in working cycles each time, charging mechanism, feeding pressure mechanism and shedding mechanism all should accurately and reliably coordinations.
At present, the locking device in existing banbury shedding mechanism mainly contains slide block type locking mechanism and curvature crank type locking mechanism two kinds of forms.In curvature crank type locking mechanism, the movement locus due to lower lock pad is one section of circular arc, and therefore, the contact of the upper lock pad on lower lock pad and discharging gate seat is linear contact lay.Banbury is in mixing process, the pressure that lower top bolt bears passs locking device by upper locking dig pass, and be linear contact lay between upper and lower lock pad, its contact position also exists huge pressure, and plate-turning door does the higher switch motion of frequency, must cause the sharp wear of two lock pads.
Summary of the invention
The purpose of this utility model is to provide a kind of discharge door of banbury mixer locking device adopting curvature crank type locking mechanism.
The utility model adopts following technical scheme to realize its goal of the invention, a kind of discharge door of banbury mixer locking device, it comprises base, the cylinder body of locking cylinder is connected with base by bearing pin, one end of drive connecting rod, passive connecting rod is connected with base respectively by bearing pin, the other end is connected with locking base by bearing pin, and lower lock pad is arranged on locking base, and the piston rod of locking cylinder is connected with drive connecting rod by bearing pin; Described drive connecting rod, passive connecting rod and base, the line of centres of locking four bearing pins that base is connected are flat shape quadrangle, and the contact surface of lower lock pad is equal with the angle of horizontal plane with the contact surface of upper lock pad with the angle of horizontal plane.
Owing to adopting technique scheme, the utility model achieves goal of the invention preferably, reciprocating mechanism is parallel-crank mechanism, make the contact of lower lock pad and upper lock pad change face into by linear contact lay to contact, substantially increase the bearing capacity of upper and lower lock pad, reduce the wearing and tearing of upper and lower lock pad, and then reduce the excessive risk of locking device action, improve stability and the economy of locking device.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, in existing curvature crank type locking mechanism, it comprises base 1, and the cylinder body 2 of locking cylinder is connected with base 1 by bearing pin 3, and the piston rod 7 of locking cylinder is connected with connecting rod 4 by bearing pin 3.When locking cylinder work drivening rod 4 moves, the movement locus due to lower lock pad 5 is one section of circular arc, and therefore, lower lock pad 5 is linear contact lay with the contact of the upper lock pad 6 on discharging gate seat.Banbury is in mixing process, the pressure that lower top bolt bears passes to locking device by upper lock pad 5, and owing to being linear contact lay between upper and lower lock pad, its contact position also exists huge pressure, and plate-turning door does the higher switch motion of frequency, must cause the sharp wear of two lock pads.
As shown in Figure 2, a kind of discharge door of banbury mixer locking device, it comprises base 1, the cylinder body 2 of locking cylinder is connected with base 1 by bearing pin 3, one end of drive connecting rod 9, passive connecting rod 8 is connected with base 1 respectively by bearing pin 3, the other end is connected with locking base 10 by bearing pin 3, and lower lock pad 5 is arranged on locking base 10, and the piston rod 7 of locking cylinder is connected with drive connecting rod 9 by bearing pin 3; Described drive connecting rod 9, passive connecting rod 8 and base 1, the line of centres of locking four bearing pins that base 10 is connected are flat shape quadrangle, and the contact surface of lower lock pad 5 is equal with the angle of horizontal plane with the contact surface of upper lock pad 6 with the angle of horizontal plane.
During the utility model application, locking cylinder works, the piston rod 7 driven forward drive connecting rod 9 of locking cylinder is around bearing pin 3 Small-angle Rotation, and then drive locking base 10, lower lock pad 5 and passive connecting rod 8 to move, realize lower lock pad 5 translational forward movement to contact with upper lock pad 6, complete the locking action of discharge door of banbury mixer locking device.When the piston rod 7 of locking cylinder pulls back drive connecting rod 9 around bearing pin 3 Small-angle Rotation, and then drive locking base 10, lower lock pad 5 and passive connecting rod 8 to move, the lower lock pad 5 of realization backward translational motion is separated with upper lock pad 6, completes the unlocking action of discharge door of banbury mixer locking device.
Claims (1)
