Description

Slitting apparatus of sheet rubber

The present invention is a sheet rubber slitting device that cuts the state of the sheet rubber in the longitudinal direction of a certain width in accordance with the equipment of the extrusion process and the amount of rubber used before the rubber for tire production completed in the refining process during the tire manufacturing to the extrusion process, the next step More particularly, the present invention relates to a sheet rubber slitting device, in which sheet rubber is cut in the longitudinal direction of a uniform width to make a rubber ribbon of a required width, which can be wound on a trolley while improving durability by simplifying the structure. .

When manufacturing tires, the rubber mass from the mixer of the refining process is sheeted and loaded on a pallet and transported to the next process. At this time, the sheet rubber is fixed width according to the extrusion process equipment and the amount of rubber used. Cut in the longitudinal direction of the to be used in the rubber ribbon method wound on the truck.

However, in an extrusion facility using a small amount of rubber, such as a small extruder, the size of the rubber supplied is larger than the rubber inlet size of the extruder.

Accordingly, the present invention has been invented to solve the above conventional problems, while simplifying the configuration of the cutting knives while being able to cut and supply a uniform width when a plurality of sheet rubbers are cut in the longitudinal direction of a certain width. It is an object of the present invention to provide a sheet rubber slitting device with improved equipment durability.

In the present invention for achieving the above object, in the slitting device of the sheet rubber provided with upper and lower knives facing each other to cut a plurality of sheet rubber conveyed through a moving belt conveyor in the longitudinal direction of a predetermined width, The lower knives are fixed to the lower shaft at regular intervals, and the upper knives are spaced apart at equal intervals from each other via a plate spring washer on the upper shaft, and the cutting knives of the upper knives are urged by the close air cylinder. Full contact is made by the dish spring washer while the upper shaft on which the upper knives are mounted is configured to be operated up / down by an up / down cylinder.

As described above, the slitting device for sheet rubber according to the present invention can be uniformly divided into a rubber sheet having a width suitable for a compaction equipment using a small amount of rubber such as a small extruder, and the durability of the equipment can be simplified by simplifying the structure. Has the effect of improving.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the entire equipment for winding the sheet in the form of rubber ribbon by cutting a plurality of rubber sheets to which the slitting device of the sheet rubber applied according to the present invention in the longitudinal direction, Figure 2 is a main portion of the sheet rubber It is a figure which shows the slitting apparatus.

Referring first to the equipment as shown in FIG. 1 to which the present invention is applied, the sheet rubber 101 loaded on the mounting table 100 is moved through the belt conveyors 102a and 102b for moving to a constant width in the slitting device 103. It is cut in the form of a plurality of rubber ribbon 104 in the longitudinal direction of the wound through the fastener 106, Festooner (105).

Here, the slitting device of the sheet rubber according to the present invention is installed facing each other to cut a plurality of sheet rubber 101 carried through the belt conveyor 102a for movement in the longitudinal direction of a predetermined width as shown in FIG. In the sheet rubber slitting apparatus having upper and lower knives 1 and 2, the lower knives 2 are fixed to the lower shaft 3 at regular intervals, and each of the upper knives 1 is upper A plate spring washer (5) consisting of a nut for rolling bearings and a rolling bearing washer (5) is installed on the shaft (4) and spaced apart from each other at equal intervals, and the upper knifes (1) are attached to the air cylinder (6) for close contact. The upper shaft 4 and the upper knife 1 operate in the axial direction by sliding the cylinder in the axial direction so that the upper knife 4 and the lower knife 2 operate in the axial direction. And the upper shaft 4 on which the upper knives 1 are mounted is precisely in close contact with the lower knife 2 by the elastic force of the plate spring 5 installed on each of the upper knives 1. It is connected to the cylinder 7, and the up / down cylinder 7 is structured to operate up / down.

The lower knifes 2 here are movable belt conveyors 102a and 102b via a chain 8 so that they can be driven at the same speed as the movable belt conveyors 102a and 102b while being fixed to the lower shaft 3. Is connected to a known drive unit.

In addition, the upper knives 1 installed on the upper shaft 4 are provided with a dish spring washer 5 between the upper knives 1 for close contact with the corresponding lower knives 2, The upper knives 1 are lowered by the up / down cylinders 7 to be urged with the air cylinder 6 for close contact with the lower knives 2, the front upper ends of the upper knives 1. The knife 1a is fixed to the upper shaft 4.

Therefore, as shown in FIG. 2, when the seat rubber 101 enters the lower knife 2 upward through the moving belt conveyor 102a, the sheet rubber 101 descends by the up / down cylinders 7 of the upper knife 1 and then the air for close contact. The upper shaft 4 and the entire upper knife 1 are slid into close contact with the lower knife 2 by the negative force of the cylinder 6, whereby each shear knife 1a and the lower knife 2 are in close contact with each other. For this purpose, the elastic force of the disc spring 5 installed on the upper knife 1 is operated.

Through the close contact between the upper knife 1 and the lower knife 2, the sheet rubber 101 is always cut in the longitudinal direction of a constant width to the trolley 106 in the form of rubber ribbons 104 having several suitable widths. It can be wound up.

On the other hand, when the sheet rubber 101 is not cut, the upper knives 1 are moved back by the release force of the close air cylinder 6 and the restoring force of the dish spring washers 5, and then up / down. It is lifted by the cylinder 7 and spaced apart from the lower knives 2.

1 is a view showing the whole facility for cutting the rubber sheet for tire manufacturing to which the slitting device for sheet rubber according to the present invention is applied in the longitudinal direction and wound on a trolley;

Figure 2 is an enlarged view showing a slitting device of sheet rubber according to the present invention.
