Abstract
The invention discloses a forward and reverse blade cutter capable of cutting rubber in a rotating manner. The forward and reverse blade cutter comprises a left cutter body fixing end, a right cutter body fixing end, a cutter, a porous plate and a nose rotating cylinder, wherein the left end and the right end of the cutter are respectively fixed at the left cutter body fixing end and the right cutter body fixing end, the left cutter body fixing end and the right cutter body fixing end are respectively connected with the nose rotating cylinder, the cutter is composed of a forward blade, a middle blade and a reverse blade, and the forward blade, the middle blade and the reverse blade are arranged on a discharging surface of the porous plate. The forward and reverse blade cutter capable of cutting rubber in the rotating manner disclosed by the invention has a simple structure, the cutter body is arranged on a rubber discharging surface of the porous plate, when the cutter stops rotary motion, a front angle, a distributing arc and a rear angle of the cutter body and a middle cutter body structure reduce obstacles to sizing material extrusion, the problem that the sizing material is against the cutter and the problem of nose resistance are solved, when the cutter is in the rotary motion, the front angle of the forward blade, the front angles of a material rolling arc and the negative blade and the material rolling arc cut the sizing material on a porous plate disc at the same time, and a middle blade structure is arranged between the forward blade and the reverse blade, thus a middle rubber discharging hole of the porous plate can not be blocked.
Description
Technical field
The present invention relates to a kind of rotation and cut the positive and negative sword cutting knife of glue.
Background technology
Once refine the glue method and be emerging in recent years rubber refining glue new technology, the rubber rubber strainer of Φ 350 big specifications is this new process of cooperation and the new equipment developed, and the head in this equipment is cut the technology that glue is a key; Especially cutting knife is important especially; The sizing material length of in new rubber mixing technique, rubber strainer being cut off owing to new technology, the head resistance, indexs such as continuous running have all had concrete regulation; The cutting knife of original form can not satisfy instructions for use fully; To the Cutting Length of sizing material, the head resistance does not have concrete requirement in undersized rubber rubber strainer in the past, in addition manpower rein in disconnected sizing material with steel wire can; This moment, the problem of cutting knife did not become key, and variety of issue never is resolved.
Summary of the invention
The purpose of this invention is to provide a kind of rotation and cut the positive and negative sword cutting knife of glue.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: the positive and negative sword cutting knife of glue is cut in a kind of rotation; Comprise cutter hub left side stiff end, the right stiff end of cutter hub, cutting knife, porous plate and head rotating cylinder; Said cutting knife right ends is separately fixed at cutter hub left side stiff end and the right stiff end of cutter hub; Cutter hub left side stiff end is connected with the head rotating cylinder respectively with the right stiff end of cutter hub; Said cutting knife is made up of positive blade, middle blade and anti-blade, and said positive blade, middle blade and anti-blade are positioned at the charge level that of porous plate.
Said head rotating cylinder drives the positive blade of cutting knife, middle blade and anti-blade rotation cutting.
Said positive blade and anti-blade all have anterior angle, front-angle, coiled strip arc, relief angle, shunting arc and angle, back to constitute.
The positive and negative sword cutting knife of glue is cut in a kind of rotation of the present invention, and simple in structure, cutter hub is positioned at porous plate plastic emitting face; The front-angle of cutter hub when cutting knife stops gyration, shunting arc, back angle and middle structure of the cutter body reduce obstruction that sizing material is extruded; Solved sizing material top cutter problem, head resistance problem, the anterior angle of positive blade when cutter is done gyration; The anterior angle of coiled strip arc and anti-blade, the coiled strip arc cuts the sizing material on the porous plate card simultaneously, is the middle plastic hole that middle edge structure can not be blocked porous plate equally in the middle of the positive and negative blade; Along with sizing material top cutter problem, the solution of head resistance problem, and then solved measured length cutting problem.
Description of drawings
Fig. 1 is the structural representation that the positive and negative sword cutting knife of glue is cut in a kind of rotation of the present invention.
Fig. 2 is positive and negative sword cutting knife knife edge angular and the cut direction sketch map that glue is cut in a kind of rotation of the present invention.
Among the figure: 1, cutter hub left side stiff end, 2, positive blade, 3, middle blade, 4, anti-blade, 5, the right stiff end of cutter hub, 6, the head rotating cylinder, 7, porous plate; 8, cutting knife; C, cutting knife direction of rotation; D, cut direction; E, plastic emitting direction.
The specific embodiment
As depicted in figs. 1 and 2, the positive and negative sword cutting knife of glue is cut in rotation, comprises cutter hub left side stiff end 1, the right stiff end 5 of cutter hub, cutting knife 8, porous plate 6 and head rotating cylinder 7, and the right ends of cutting knife 8 is separately fixed at cutter hub left side stiff end 1 and the right stiff end 5 of cutter hub; Cutter hub left side stiff end 1 is connected with head rotating cylinder 7 respectively with the right stiff end 5 of cutter hub, and cutting knife 8 is made up of positive blade 2, middle blade 3 and anti-blade 4, and just blade 2, middle blade 3 and anti-blade 4 are positioned at the charge level that of porous plate, and cutting knife is by the left stiff end of cutter hub; Positive blade, middle blade, anti-blade, the right stiff end of cutter hub is arranged successively; Head rotating cylinder 7 drives the positive blade of cutting knife, middle blade, anti-blade, rotation cutting; Positive blade, anti-blade be by anterior angle B, front-angle B1, coiled strip arc R; Relief angle a, shunting arc R1 and back angle a1 constitute, and knife edge angular is selected in cutting process: back angle a1=60 o, the main effect that higher value is got at the angle, back is in order to increase the axial force in the cutting process; Thereby exploded, diametric is to resistance, and front-angle B1=35 o reduces because of the frictional force of cutting knife rotation with sizing material, avoids rupturing because of cutting stress is excessive; Relief angle a=25 o shunts arc R1=20, and grinds 1 millimeter cutting rib; It is in order to increase axial cutting force that relief angle is got smaller value, and the cutting rib that grinds has the effect of picking-up to sizing material in cutting process, avoid blade to be attached on the porous plate face; It is to form the peak mouth that anterior angle B=40, coiled strip arc R=25 anterior angle and looping channel get higher value, makes cutting knife sharp; The incision sizing material is smooth, and the positive and negative sword cutting knife of glue is cut in rotation of the present invention, changes cutter hub radial angle and middle structure of the cutter body and reduces obstruction that sizing material is extruded; Solved sizing material top cutter problem, the head resistance problem, and then solved the Cutting Length problem.
