Abstract

The utility model relates to a large-bottleneck leftover rotary cutting device for an extrusion blowing machine. The device comprises a knife rest, wherein the knife rest consists of a spindle, a motor, a motor base, a rotating arm, a cutter shaft and a circular blade; the cutter shaft and the spindle are respectively connected on two sides of the rotating arm; the cutter shaft is parallel to the spindle; the spindle is driven by a speed-reducing motor to rotate and drives the cutter shaft to do circular motion around the spindle through the rotating arm; and the cutter shaft is provided with a floating circular blade, and the circular blade can freely rotate and can float for 2-3mm up and down. The device provided by the utility model has the advantages that because a disc cutter can freely rotate, the rotary cutting process is rolling-pressing cutting, and scraps are not generated; the whole circle of blade of the periphery of the disc cutter is used for rolling cutting, compared with cutting by using a fixed cutter, the blade is hardly worn, so that the cutter is more durable; and moreover, a floating spring is arranged on the spindle of the disc cutter and can float up and down, due to a groove design of an airbag, the cutter can automatically track, so that a bottleneck slightly deformed in blowing procedure can be cut accurately by the cutter.

Description

A kind of big bottleneck clout rotary cutting apparatus of extruding and blowing machine
Technical field
The utility model relates to a kind of corollary apparatus of plastic extrusion blowing machine, particularly relates to a kind of big bottleneck clout rotary cutting apparatus of extruding and blowing machine.
Background technology
Traditional way that cuts of big its bottleneck clout of bottle that extruding and blowing machine is made generally adopts the manual clout that cuts, and manual otch is difficult to unified standard, and percent defective is high, and inefficiency.
Summary of the invention
The purpose of the utility model just provides a kind of big bottleneck clout rotary cutting apparatus of extruding and blowing machine, otch standard, no waste product, high efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of big bottleneck clout rotary cutting apparatus of extruding and blowing machine; Comprise: knife rest; It is characterized in that: described knife rest is made up of main shaft, motor, motor cabinet, turning arm, cutter shaft, circular shear blade; Cutter shaft and main shaft are connected to the both sides of turning arm, and cutter shaft is parallel with main shaft, and main shaft is made circular motion by the reducing motor driven in rotation and through turning arm drive cutter shaft around main shaft; Described cutter shaft is equipped with floating type circular shear blade, and circular shear blade can rotate freely, and can do 2~3 millimeters up and down and float; The dead in line of described main shaft and bottle, the length of turning arm are the cutter shaft length that circular shear blade can cut the bottleneck clout when motion of main shaft.
The top of described floating type its cutter shaft of circular shear blade is through the cutter shaft connecting hole of cutter shaft bearing connection turning arm, and the two ends up and down of cutter shaft bearing are respectively equipped with the floating spring that is connected with cutter shaft, and cutter shaft can slide up and down along the cutter shaft bearing.
Described motor cabinet is the flexible lamp support; The flexible lamp support is made up of flat-removing air cyclinder, cylinder holder, guide rail; The piston rod of described flat-removing air cyclinder is connected with motor cabinet on the main shaft; Flat-removing air cyclinder is fixedly connected with the cylinder holder, and holder is connected with motor cabinet with the guide rail slide block through guide rail, and the direction that its guide rail slides is identical with the direction that cylinder piston rod moves.
Described circular shear blade is fixed on the lower end of cutter shaft.
The utlity model has following having a few:
1, because disc cutter can rotate freely, the rotary-cut process is the rolling crush-cutting, does not produce chip;
2, the peripheral whole circle cutting edge of disc cutter all is used for the cutting of rolling, and compares the dead knife cutting blade and weares and teares hardly, makes cutting knife more durable;
3, the main shaft of disc cutter is provided with floating spring, can fluctuate, and to the bottleneck of blowing traverse slight deformation, because of the groove design of air bag, blade can automatic tracking, accurately cutting.
Description of drawings
Fig. 1 is the schematic perspective view of one of them embodiment of the utility model.
Fig. 2 is the local internal structure sketch map that amplifies in the A place of Fig. 1.
Fig. 3 is the wherein front schematic view of second embodiment of the utility model.
Fig. 4 is the schematic perspective view of Fig. 3.
The specific embodiment
Like Fig. 1, shown in Figure 2; The utility model comprises: knife rest; Described knife rest is made up of main shaft 3, motor 1, motor cabinet 2, turning arm 4, cutter shaft 7, circular shear blade 6; Cutter shaft and main shaft are connected to the both sides of turning arm, and cutter shaft is parallel with main shaft, and main shaft is made circular motion by the reducing motor driven in rotation and through turning arm drive cutter shaft around main shaft; Be connected with floating type circular shear blade on the described cutter shaft, circular shear blade is fixed on the lower end of cutter shaft 7, and circular shear blade can rotate freely, and can do 2~3 millimeters up and down and float; The dead in line of described main shaft and bottle 5, the length of turning arm is decided according to mouth sizes, and the length of turning arm is the cutter shaft length that circular shear blade can cut the bottleneck clout when motion of main shaft.
The top of described floating type circular shear blade 6 its cutter shafts 7 connects the cutter shaft connecting hole 12 of turning arm through cutter shaft bearing 11,13; The two ends up and down of cutter shaft bearing are respectively equipped with the compression spring 14,15 that floats that is connected with cutter shaft, and cutter shaft can slide up and down along the cutter shaft bearing.
Like Fig. 3, shown in Figure 4; Be another embodiment sketch map of the utility model, described motor cabinet 2 is the flexible lamp support, and the flexible lamp support is made up of flat-removing air cyclinder 8, cylinder holder 9, guide rail 10; The piston rod of described flat-removing air cyclinder is connected with motor cabinet 2 on the main shaft; Flat-removing air cyclinder is fixedly connected with the cylinder holder, and holder is connected with motor cabinet with the guide rail slide block through guide rail 10, and the direction that its guide rail slides is identical with the direction that cylinder piston rod moves.Present embodiment is in halted state, and turning arm is fixed in a certain angle, and at the effect lower slide slow astern set a distance of cylinder, convenient bottle to be cut gets into the rotary-cut position.During work, the rotary-cut assembly advances to the precalculated position, and main shaft drives circular shear blade and carries out rotary-cut around bottleneck.
The utility model is applicable to the cutting of the bigger bottleneck clout of bore, be not suitable for use the roller ring cutting as greater than 80mm the time, and this device is to bottleneck and the body diameter is big or body out-of-shape bottleneck air bag clout excises automatically and design.Body is vertically fixing in the excision process; Electric machine main shaft is fixedly connected and rotates synchronously with rotation wall 4; The bottleneck dead in line of electric machine main shaft and bottle 5; In the course of work, cutter shaft is in the rotation around the effect that receives the otch resistance in the bottleneck revolution, and making cutting process is not single-point cutting edge cutting but the circle of whole circular knife encloses cutting edge at crush-cutting.The cutting edge wearing and tearing so both can have been reduced, the generation that also can avoid cutting chip.
But this device on-line equipment is produced with the bottle blowing machine on line on bottle blowing machine, also can be connected the bottle blowing machine work that is independent of with bottle supply device such as conveyer belt.
The utility model is not limited to described implementation method, and under the utility model design that does not exceed claim, the personnel for having the ABC in field under the utility model can implement a lot of distortion, and these modification also belong to the scope of the utility model.
