Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, and more specifically, it is an electrothermal hook knife type steel cord three-station cutting machine. Background Art
[0002] As is well known, in the process of tire production and manufacturing, the design of the belt angle of the engineering meridian giant tire is an important process to improve the high-speed durability performance. The change of the belt angle can affect the inflation section width, outer diameter, stress, strain, strain energy density, etc. of the belt layer endpoints of the tire, which will directly restrict the performance of the giant radial tire product. The traditional process uses an angle similar to that of the engineering meridian tire, and a diagonal cutting machine can directly cut the steel cord calendered by the calender at a certain angle. Since the giant radial tire has similarities with the engineering meridian tire, but there are also certain differences. If it is produced according to the production process of the engineering meridian tire, it will directly affect the durability performance of the giant radial tire product. If we want to solve the problem of improving the durability performance of the giant radial tire product, we need to adjust the angle of some belt layers. If the angle is reduced, the width of the steel cord calendered by the existing calender cannot be cut on the diagonal cutting machine because the hypotenuse length after cutting exceeds the length of the knife face. It is necessary to reduce the width of the steel cord calendered by the calender for production, which not only seriously affects the production efficiency, but also the narrowed rubber damper plate rubs against the surface of the roller for a long time, resulting in differences in the thickness at the friction position when producing wide-width steel cord, and there is a certain risk to the thickness quality of the calendered steel cord. If small-angle cutting cannot be carried out, it will directly affect the durability performance of the giant radial tire product, and there are great potential quality risks. There is an urgent need for a set of special equipment to cut the width of the steel cord calendered by the calender to ensure that the efficiency of the calender is not affected. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides an electrothermal hook knife type steel cord three-station cutting machine, which effectively solves the problem of reducing the width of the steel cord calendered by the calender for production because the hypotenuse length after cutting the original-width steel cord exceeds the length of the knife face and cannot be cut on the diagonal cutting machine.

The lower part of the movable guide sleeve is connected to a knife holder through a knife lifting cylinder with a guide rod. The knife holder is connected and fastened with a heating plate and a hook-shaped knife. The cutting edge of the hook-shaped knife sinks into the reserved vacancy of the cutting roller, and the cutting edge of the hook-shaped knife is flush with the surface of the cutting roller; a fabric spreading support roller is installed on the machine frame behind the cutting device, and a coiling device is provided behind the fabric spreading support roller.

[0015] In the figure, the utility model is provided with a machine base 1. A pay-off device 2, a deviation rectifying device 3, a cutting device, a coiling device and an electrical control system are respectively installed on the machine base 1. A pay-off device 2 with a deviation rectifying device 3 is installed at the rear of the machine base 1. A deviation rectifying detection probe 4 is installed on the frame behind the pay-off device 2. The pay-off device 2 is used to detect the steel cord fabric A2 before deviation rectification of the material to be cut, and timely transmit the deviation signal to the deviation rectifying device 3 to correct the position of the pay-off device 2. A positioning edge retaining roller 5 and a spreading and pressing roller 6 are installed on the frame behind the deviation rectifying detection probe 4. The pay-off device 2 has a braking function, and the pneumatic brake is controlled by an air source and a proportional valve, effectively preventing the steel cord fabric from not being flattened due to unstable or no tension, which affects the cutting quality. The pay-off device 2 has the function of a deviation rectifying device. A cutting device is installed behind the spreading and pressing roller 6. The cutting device has two symmetrically arranged knife seat height adjusting screws 7 and eight knife seat height adjusting nuts 8 to adjust and fasten the knife seat 9. Two sets of movable guide sleeves 10 with different widths can be moved and adjusted are installed in the middle of the knife seat 9. After moving to the standard position, the position is fixed by fixing screws 11. The lower part of the movable guide sleeve 10 is connected to a cutter holder 13 through a cutter lifting cylinder 12 with a guide rod. The cutter holder 13 is provided with a heating plate 14 and a hook-shaped cutter 15 which are connected and fastened. The position of the hook-shaped cutter 15 can be adjusted by the knife seat height adjusting screw 7 and the knife seat height adjusting nut 8 for the knife seat 9. The cutter head of the hook-shaped cutter 15 sinks into the reserved vacancy of the cutting roller 16 to ensure that the blade of the hook-shaped cutter 15 is flush with the surface of the cutting roller 16, and the cutting is without resistance. A spreading roller 17 is installed on the frame behind the cutting device. A coiling device is installed behind the spreading roller 17. The coiling device is provided with a movable coiling chuck 18 and a rotating coiling chuck 19 for combined use. The movable coiling chuck 18 is supported by a cylinder fixing seat 22 fixed on the machine base 1. The chuck driving cylinder 21 moves linearly along the direction of the chuck sliding sleeve 20. The rotating coiling chuck 19 is connected to the motor synchronous pulley 25 of the driving motor 24 through a rotating chuck synchronous pulley 23 to drive the coiling square bar 26 and the coiling shaft 27 to rotate. Safety optoelectronics 28 are arranged around the machine base 1. A cutter safety guard 29 is added outside the cutting part of the hook-shaped cutter 15. An operation cabinet 30 is installed on the machine base 1 through a bracket. Control switches such as emergency stop and manual / automatic are arranged on the operation cabinet 30, and a cutter adjustable temperature heating controller 31 with adjustable temperature is arranged. The cutter adjustable temperature heating controller 31 is connected to the heating plate 14. The temperature of the hook-shaped cutter 15 can be adjusted between 30°C and 300°C through the cutter adjustable temperature heating controller 31 with adjustable temperature according to the process requirements, so as to avoid scorching caused by high temperature. The spreading and pressing roller 6 and the spreading roller 17 adopt an inverted eight-shaped spiral structure design, effectively flattening the material through rotation.
[0016] The specific implementation method is as follows: The operator installs the wire cord fabric A1 to be unrolled and cut on the unrolling device 2 station on the machine base 1. Pass the wire cord fabric A2 before deviation correction and cutting through the deviation correction detection probe 4. Rely on the deviation correction detection probe 4 to detect the wire cord fabric A2 before deviation correction and cutting, and promptly transmit the deviation signal to the deviation correction device 3 to correct the position of the unrolling device 2. The wire cord fabric A3 after deviation correction and cutting is transmitted to the lower part of the fabric spreading and pressing roller 6 through the positioning edge retaining roller 5, and after being spread and flattened, it enters the cutting device. Manually cut the wide-width wire cord fabric into three equal parts according to the standard width. After the cut wire cord fabric B1 passes above the cutting roller 16, it is transmitted through the fabric spreading roller 17, and the three narrow-width cut wire cord fabrics B1 are respectively wound and fixed on the 3 winding shafts 27 on the winding square bar 26. After the wire cord fabric is tightened and flattened by operating the jog winding switch on the operation cabinet 30, manually operate the cutting knife lowering switch, and use the cutting knife lifting cylinder 12 with unrolling to drive the cutting knife holder 13, the heating plate 14, and the hook-shaped knife 15 to descend to the reserved vacancy of the cutting roller 16. After checking on-site without errors, switch the manual-automatic switch on the operation cabinet 30 to automatic, and after starting the automatic start button, the electric heating hook knife type three-station wire cord fabric cutting machine will run automatically. After the cutting is completed, press the automatic stop button on the operation cabinet 30 to stop, and switch the manual-automatic switch on the operation cabinet 30 to manual. Manually operate the cutting knife rising switch, and use the cutting knife lifting cylinder 12 with unrolling to drive the cutting knife holder 13, the heating plate 14, and the hook-shaped knife 15 to rise away from the cutting roller 16. Then, use a lifting tool to lift the cut and wound wire cord fabric B2 on the 3 winding shafts 27 on the winding square bar 26. Operate the opening switch of the mobile winding chuck 18 on the operation cabinet 30, and use the air source to drive the chuck driving cylinder 21 of the cylinder fixing seat fixed on the machine base 1 to perform a linear opening movement along the chuck sliding sleeve 20 direction. After unloading the cut and wound wire cord fabric B2, repeat the above cyclic operation. The operation of dividing the wide-width wire cord fabric into three equal parts meets the cutting width requirements of the diagonal cutting machine, effectively solves the problem that the bevel length of the original wide-width wire cord fabric exceeds the knife surface length after cutting and cannot be cut on the diagonal cutting machine, and the problem of reducing the width of the wire cord fabric calendered by the calender. Moreover, the narrowed rubber retaining plate rubs against the roller surface for a long time, resulting in differences in the thickness at the friction position when producing wide-width wire cord fabric, posing a certain risk to the thickness quality of the calendered wire cord fabric. If small-angle cutting cannot be performed, it will directly affect the durability of giant radial tire products. Eliminate the potential quality risks, improve production efficiency and the durability of giant radial tire products.
