technical field

The utility model relates to a cutting device, in particular to an automatic cutting device for engineering tire cords.

Background technique

In the previous engineering tire cord cutting structure, the bottom plate of the cutting knife is a metal plate, and the knife groove is dug out in the middle. This cutting method is easy to cut the steel wire, and it will deform the blade after a long time, which will affect the performance.

Contents of the invention

The technical problem to be solved by the utility model is to provide an engineering tire cord automatic cutting device that can increase the service life of the blade and reduce the waste of rubber material.

In order to solve the above-mentioned technical problems, the utility model includes a knife rest and a knife stand, the knife rest is provided with a cutting knife that can move left and right and is used to cut the cord rubber, and the knife rest is provided with three rows of nylon pressure rollers and The cord rubber passes through three rows of nylon rollers sequentially, and the nylon roller in the middle of the three rows of nylon rollers is a mobile nylon roller, and the bottom of the movable nylon roller is equipped with a cylinder to realize the movement of the nylon roller. Move up and down and be able to jack up the cord compound.

One side of the cutter is provided with a guide wheel, and one side of the knife table is provided with a centering seat used in conjunction with the guide wheel to ensure the consistency of the start and end positions of the cutter.

The cutter is also provided with an infrared sensor for detecting the temperature of the blade of the cutter.

The knife rest is provided with a motor and a synchronous belt driven by the motor, and the cutter is installed on the slide rail at the bottom of the knife rest through a slide block and the slide block is also affixed to the timing belt. Driven by it, it can move left and right along the guide rail.

The beneficial effects of the utility model are: the utility model can ensure that the blade does not cut the steel wire as far as possible, improves the service life of the blade, and does not need to be replaced frequently; at the same time, it can reduce the waste of rubber materials, improve the working efficiency of the tire factory, and save unnecessary waste for the enterprise. waste.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

Referring to Fig. 1 to Fig. 3, the automatic cutting device for engineering tire cord of the present utility model includes a knife holder 1 and a knife table 2, and the knife holder 1 is provided with a cutting knife 3 which can move left and right and is used for cutting cord rubber , the knife table 2 is provided with three rows of nylon pressure rollers 4 and the cord rubber material passes through the three rows of nylon pressure rollers 4 sequentially, and the nylon pressure roller in the middle position among the three rows of nylon pressure rollers 4 is a mobile nylon pressure roller, A cylinder 5 is provided at the bottom of the moving nylon pressing roller to realize the up and down movement of the moving nylon pressing roller and to lift up the rubber cord material.

One side of the cutting knife 3 is provided with a guide wheel 6, and one side of the knife table 2 is provided with a centering seat 7 used in conjunction with the guide wheel 6 to ensure the consistency of the starting and ending positions of the cutting knife 3.

The cutter 3 is also provided with an infrared sensor 11 for detecting the temperature of the cutter blade.

The knife rest 1 is provided with a motor 8 and a synchronous belt 9 driven by the motor 8, the cutter 3 is installed on the slide rail at the bottom of the knife rest 1 by a slide block 10 and the slide block 10 is also connected with the synchronous belt 9 Fixed connection, the cutting knife 3 can move left and right along the guide rail under the drive of the motor 8.

The motor 8 drives the synchronous pulley to transmit power through the synchronous belt 9, and cuts the cutter 3 from one end to the other. When the cutter 3 travels from the right side to the left side to finish cutting, the guide wheel 6 enters the centering seat 7 along the way, It plays the role of positioning and returning to the end point, so that the cutter 3 returns to the middle position of the three-row nylon pressure roller 4; the infrared sensor 11 is used to detect the cutting temperature of the cutter blade, and prevent the rubber from scorching due to excessive temperature of the blade; In the cutting state, the front and rear two large pressure rollers on the feed frame press the cord rubber, and the cylinder 5 on the cord cutting knife table 2 pushes the moving nylon pressure roller to lift the cord rubber, so that the cord rubber needs to be cut. Do a small part of the stretch to increase the distance between the steel wires. During the middle cutting process, the blade is in a free floating state and can swing slightly left and right along the cord rubber material, along the direction of the rubber material supported by the moving nylon pressure roller. Cutting in the gap between the steel wires to avoid cutting the steel wires, the cutting effect is obviously better than the previous cutting structure, basically no steel wires will be exposed.

In summary, the content of the present utility model is not limited to the above-mentioned embodiments, and those skilled in the art can propose other embodiments within the technical guidance of the present utility model, but these embodiments are all included in this disclosure. within the scope of utility models.
