Abstract
The invention discloses a rotating traction device for an injection molding machine. The rotating traction device comprises a plurality of rotating guide rollers movably connected in a circular ring support, wherein each rotating guide roller comprises a roller body, connecting rods connected to the two ends of the roller body, and rolling bodies arranged at the head parts of the connecting rods, and each connecting rod is of a freely bent hollow structure. Through the mode, the shifting and the wrinkling of tubular film bubbles can be effectively reduced, and the flatness and the winding quality of a film can be improved.
Description
Technical field
The present invention relates to injection molding art, particularly relate to a kind of rotary tractor of injection machine.
Background technology
In the production process of tradition inflation film, raw material is extruded by blowing head after melting, and blowing becomes cylindric film bubble, then through the herringbone clamping plate of draw-gear and carry-over pinch rolls, tubular film bubble is folded into sheet bilayer film, bilayer film walks around deflector roll, finally carries out rolling by winding device.
Because existing carry-over pinch rolls are fixed in annular stent, can not adjust, and the frictional force between tubular film bubble and carry-over pinch rolls, make tubular film bubble, on carry-over pinch rolls, a small amount of movement can occur, tubular film bubble is made to be difficult to invariably there will be the even phenomenon of film barrel became uneven, above-mentioned circle and thick point or the position of thin point on film cylinder substantially fixing, this thickness deviation is made to become systematic bias, the thickness deviation when rolling of film can continue accumulative superposition, the film after rolling is made to roll up thickness seriously uneven, produce quick-fried muscle phenomenon, affect flatness and the reeling quality of film.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rotary tractor of injection machine, effectively can reduce the skew of tubular film bubble and wrinkling, improve flatness and the reeling quality of film.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the rotary tractor providing a kind of injection machine, comprise the some rotary guide be movably connected in annular stent, described rotary guide comprises roll body, is connected to the connecting rod at described roll body two ends and is arranged on the rolling element of described connecting rod head, and described connecting rod is the hollow-core construction of energy free bend.
In a preferred embodiment of the present invention, described rotary guide has two, and levels stacked is rotatably connected in annular stent.
In a preferred embodiment of the present invention, described connecting rod is the nodular coiled pipe containing some joints.
In a preferred embodiment of the present invention, the joint energy free bend of described nodular coiled pipe.
In a preferred embodiment of the present invention, the pass joint number of described nodular coiled pipe is 1-3 joint.
In a preferred embodiment of the present invention, described rolling element is steel ball.
The invention has the beneficial effects as follows: adopting can the connecting rod of free bend, rotary guide is made freely regulatedly to be movably connected in annular stent, make rotary guide under the effect of the frictional force by tubular film bubble, can free adjustment, tubular film bubble is floated uniformly on rotary guide, effectively reduce the skew of tubular film bubble and wrinkling, improve flatness and the reeling quality of film.
Accompanying drawing explanation
Fig. 1 is the structural representation in rotary tractor one preferred embodiment of a kind of injection machine of the present invention;
Fig. 2 is the structural representation of rotary guide shown in Fig. 1;
In accompanying drawing, each mark is as follows: 1, annular stent, and 2, rotary guide, 21, roll body, 22, connecting rod, 23, rolling element.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1-Fig. 2, the embodiment of the present invention comprises:
A kind of rotary tractor of injection machine, comprise the some rotary guide 2 be movably connected in annular stent 1, described rotary guide comprises roll body 21, is connected to the connecting rod 22 at described roll body 21 two ends and is arranged on the rolling element 23 of described connecting rod 22 head, and described connecting rod 22 is the hollow-core construction of energy free bend.
Described rotary guide 2 has two, and levels stacked is rotatably connected in annular stent 1.Accurate position can be kept, improve intensity and rigidity, and stability is high, effectively can reduce the skew of tubular film bubble and wrinkling.
Described connecting rod 22 is the nodular coiled pipe containing some joints, and the joint energy free bend of described nodular coiled pipe, and rotary guide 2 can freely be finely tuned under the frictional force effect of tubular film bubble, effectively reduces the skew of tubular film bubble and wrinkling; The pass joint number of described nodular coiled pipe is 1-3 joint, and total length is the diameter of roll body 21.
Described rolling element is steel ball, and rotary guide 2 is movably connected in annular stent 1.
Present invention is disclosed a kind of rotary tractor of injection machine, employing can the connecting rod of free bend, rotary guide is made freely regulatedly to be movably connected in annular stent, make rotary guide under the effect of the frictional force by tubular film bubble, can free adjustment, tubular film bubble is floated uniformly on rotary guide, effectively reduces the skew of tubular film bubble and wrinkling, improve flatness and the reeling quality of film.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and Figure of description content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
