Description
Technical field
The present invention relates to processing of high molecular material machinery, a kind of automatic radial tyre cold rubber piece cutting machine that in the production process of radial-ply tyre, is used for the cold rubber piece cutting action after mixing of more clearly saying so.
Background technology
In the production process of radial-ply tyre, the cold rubber piece through mixing, compressing tablet, after parking has certain thickness and hardness, and bigger elasticity is arranged.Therefore, its cutting itemize is quite difficult.Existing cutting machine mostly utilizes to be sheared mechanism and carries out discontinuous cutting, often do not cut through, can't cut, between bar and the bar adhesion pull, separated but still in each other's thoughts.For addressing this problem, the operative employee can only cut, tear by means of manual the benefit.Therefore, production efficiency reduces greatly, and is time-consuming, and improved labour intensity." the automatic cutting cutter of planer-type rubber " that Yancheng City rubber machinery plant, Jiangsu Province produces is exactly to utilize to shear the mechanism cutting.The cutter sweep of JP2048198 Japan Patent is made up of the chopping block under a cutter and the cutter, the chopping block rapid wear, and service life is lower.In addition, cutter will be heated to 200～300 degree during cutting, contaminated environment, and the easy oxidation of film, mechanical and physical performance can descend.Be subjected to the restriction of the feeding zone size of the extruder spout size of its next procedure and calender after the cutting, cold rubber piece must cut itemize.Therefore, develop high efficiency, high-quality automatic gas cutting machine is very necessary.
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of mechanism cutting of shearing and tearing effect simultaneously that utilizes is provided, and cuts thoroughly, cuts disconnectedly, and adhesion is pullled between bar and the bar; And not heating continuous cutting, film is not aging, mechanical and physical performance does not descend; Long service life, the production efficiency height, labour intensity is low, the automatic radial tyre cold rubber piece cutting machine of non-environmental-pollution.
Summary of the invention
In order to achieve the above object, the present invention is by frame, and rack-mounted power drive system is installed in that film feed device, cutter sweep and the adhesive tape conveying device with transmission system drives constituted on the frame.Cutter sweep is by rack-mounted fork drive unit, be hinged on the fork drive unit and the hole of borrowing with holes, its middle part is installed in fork on the balance staff that is fixed on the frame with hinge, be installed in the adjustable connecting-rod of forming by two screw rods and long nut in the screw of the fork other end, the one end is installed in the other end of adjustable connecting-rod, the cutting knife of the perpendicular arm of its other end band and its middle band macropore of perpendicular arm end band aperture, be installed in the macropore of cutting knife and be fixed in tool axis on the frame, be installed in the round cutter of the perpendicular arm end of cutting knife with little axle, be fixed on the cutting roll shaft on the frame, with bearing be installed in cutting on the roll shaft sleeve and the cutting roller that is installed on the sleeve formed.Sprocket wheel is installed on the sleeve and drives with sprocket wheel chain power drive system.
The circle cutter are positioned at the front upper place of cutting roller, and the two has a difference in height and does not contact.
The fork drive unit is made of the hinge that is fixed on free bearing on the frame, is hinged on the cylinder on the free bearing, the piston rod end that is hinged on cylinder and swing link end part with hinge.This is a kind of pneumatic mode, also can adopt alternate manners such as cam.
With the pneumatic system control cylinder, make its piston rod elongation or contraction.Piston rod promotes hinge, fork, adjustable connecting-rod more successively, makes cutting knife swing, and then the working cycles that makes round cutter finish, fall and cold rubber piece is exerted pressure.Circle cutter itself are unpowered, rely on cold rubber piece to advance and drive its rotation, and cold rubber piece is cut.Can avoid cold rubber piece to heat up, free from environmental pollution.Regulate the length of adjustable connecting-rod, can adjust the position of round cutter, make to keep certain height poor between round cutter and the cutting roller.Because this difference in height between circle cutter and the cutting roller, when the cutting cold rubber piece, the adhesive tape of cutting is not fully torn under the effect of tearing of circle cutter fully, can not stick together.When cutting,, prolonged the service life of round cutter and cutting roller greatly because the circle cutter do not contact with cutting roller.
Film feed device is by being fixed on film transport frame on the frame, being installed in support roll shaft and backing roll, rack-mounted traction rollers and carry-over pinch rolls thereof on the film transport frame, being installed in conveyer belt between carry-over pinch rolls and the backing roll, being installed in the pressure roller shaft and the pressure roller thereof that are positioned at the carry-over pinch rolls top on the frame and being constituted.Sprocket wheel is installed on the carry-over pinch rolls and drives with sprocket wheel chain power drive system.
The adhesive tape conveying device by be fixed on adhesive tape on the frame carry frame, be installed in adhesive tape carry 3～6 pairs of traction rollers and carry-over pinch rolls, rack-mounted initiative roll shaft and drive rolls thereof on the frame, be installed in conveyer belt between carry-over pinch rolls and the drive roll, be installed in pressure roller shaft and the pressure roller thereof that is positioned at the drive roll top on the frame and be installed in adhesive tape carry frame upper in the carry-over pinch rolls top and corresponding with it 3～6 pairs of pressure roller shaft and pressure roller thereof constituted.Sprocket wheel is installed on the drive roll and drives with sprocket wheel chain power drive system.
Sprocket wheel chain power drive system is made of reducing motor, minor sprocket, chain, hinge wheel etc., send power to sleeve, carry-over pinch rolls and drive roll respectively, make the conveyer belt of cutting roller, film feed device and the conveyer belt rotation work of adhesive tape conveying device, finish cutting and conveying task.
Cold rubber piece through mixing, compressing tablet, after parking is carried by the conveyer belt of film feed device, is flattened by pressure roller simultaneously, delivers to the cutter sweep place, cuts itemize by cutter sweep.Adhesive tape after the cutting then is transported to assigned address by the adhesive tape conveying device, is transported by dumper at last, enters down operation.
Task of the present invention comes to this and finishes.
The invention provides a kind of mechanism cutting of shearing and tearing effect simultaneously that utilizes, cut thoroughly, cut disconnectedly, adhesion is pullled between bar and the bar; And not heating continuous cutting, film is not aging, mechanical and physical performance does not descend; Long service life, the production efficiency height, labour intensity is low, the automatic radial tyre cold rubber piece cutting machine of non-environmental-pollution.It can be widely used in the automatic cutting of radial tyre cold rubber piece.
