Description

The horizontal cutting conveyer belt

Technical field

The utility model is a kind of horizontal cutting conveyer belt that is used to make rubber tyre, belongs to rubber manufacturing machinery and industrial automation field.

Background technology

Along with the quick growth of domestic automobile production and sales volume, higher technical standard has been proposed for the design and the service property (quality) of rubber tyre.

In tire production, need utilize cutter that the film semi-finished product of different size such as wirecord fabric, inner liner and model are cut, offer operations such as follow-up joint, pressing, anti-package and use to process fetus.

Existing severing technology adopts the negative clearance between cutter hub and the transfer roller that the butt formula is carried out severing normally with film transport to severing station.Because film self has certain elasticity and toughness, when producing continuously, be difficult for disposable cut-out.In addition, when long-time use rear knife edge place forms certain wearing and tearing and causes the spacing of cutter hub and transfer roller to strengthen, be difficult to realize exactly tool setting.

Usually the solution of employing is, heat for cutter hub and promptly take high-temperature machining glue mode, but the too high adhesion that is prone to cause sizing material and cutter hub again of temperature.

Many weak points of above-mentioned prior art have all caused film to cut not exclusively, or the generation of phenomenon such as cut surface sizing material adhesion, thereby bring certain problem for operation such as follow-up joint, have influence on the operation and the fetus crudy of automatic continuous production.

The utility model content

The utility model provides a kind of horizontal cutting conveyer belt, and its purpose is to address the above problem and improves to cut-off knife and heating arrangement, realizes the smooth implementation of severing technology and the suitable adjusting of heating-up temperature.

The purpose of design of the utility model is, improves cutter hub heat regulation structure and temperature control method effectively, guarantees to cut in suitable temperature range to carry out, and is complete with protection otch sizing material and severing.

For realizing above-mentioned purpose of design, described horizontal cutting conveyer belt mainly includes:

Be carried on the main frame on the supporting seat,

Main frame is provided with, and drives and vertically carries several conveying rollers of film through reducing motor, send roller one group of horizontal cutting device to be installed on vertical at roller.

The difference with the prior art part is that described horizontal cutting device has, and is arranged on by the transfer roller of severing film below and is arranged on by the support of severing film top.

Wherein, the inboard two end axles of support is established a horizontal main shaft, and spindle nose connects drive motors, at the sheathed rotating knife of main shaft periphery;

Be pasted with the Electric radiant Heating Film that connects external power source and temp control switch at the rotating knife sidepiece.

Like above-mentioned basic scheme characteristic, because Electric radiant Heating Film is to the heating of cutter hub, when cutting the moment that action is carried out, blade forms otch, the severing film fully to cutting through rotating knife and transfer roller again with the sizing material on higher temperature fusing film surface.

Temp control switch is set controls heating effectively, promptly control the blade temperature within suitable scope to rotating knife.Temperature is too high, is easy to burn film, and temperature is too low, is difficult for the fusing sizing material again and increases the resistance of machine cut.

Film is fed forward continuously, can not be hindered or stagnate in the severing process in order to improve; The improvement project of supplying power continuously to heater is; Described Electric radiant Heating Film, through the carbon brush configuration that electric wire connection one is set on the horizontal main shaft, carbon brush configuration connects external power source.

For overcoming the continuously good switching performance of rotation holding circuit of main shaft, more preferred measure is,

Carbon brush configuration includes the carbon brush holder that is installed on support, and the one group of spring that holds out against a pair of carbon brush is respectively downwards arranged in the carbon brush holder set inside;

The bottom of carbon brush is closely against electric wire through copper ring, between between 2 carbon brush, is separated with the insulation spacer.

For guaranteeing stable connection the between rotating knife and the Electric radiant Heating Film, a pressing plate can be installed on main shaft, pressing plate is pressed on Electric radiant Heating Film from the outside sidepiece of rotating knife.

As stated, the advantage that has of the utility model horizontal cutting conveyer belt is:

1, can be implemented under the heated condition and to carry out severing technology, cut fully, otch is smooth and help operations such as follow-up joint, pressing, anti-package, helps improving the crudy of green tyres;

2, temperature control, the scalable of cutter hub heating had not only guaranteed to cut smoothly, but also had protected the sizing material of cut surface.
