Description

Cutting induction device of cutting machine

Technical Field

The invention belongs to the technical field of cutting machines, and particularly relates to a cutting induction device of a cutting machine.

Background

The cutting machine is a device commonly used in the light industry, is pressurized to a cutting die by means of the action force of machine movement, performs punching processing on nonmetallic materials, and is suitable for punching and cutting nonmetallic materials such as foaming materials, paperboards, textiles, plastic materials, leather, rubber, packaging materials, floor materials, carpets, glass fibers, cork and the like by means of the punching force generated by the cutting die by means of machines. For materials with high viscosity and toughness, the existing cutting machine is easy to generate partial adhesion in the punching cutting process and is difficult to completely cut; in addition, with a four-column cutting machine, the stamping forces provided by the four stamping columns are often difficult to be precisely equal, resulting in uneven stamping surfaces and also resulting in a partial cutting surface of the cutter that cannot be cut in place, thereby failing to completely cut the product. The existing cutting machine does not have a cutting induction device, whether a product is completely cut cannot be judged, if the raw materials which are not cut flow into a later material receiving post, the product needs to be manually torn from the raw materials, so that the appearance quality of the edge of the product is poor, and the material receiving efficiency is affected.

Disclosure of Invention

The invention aims to provide a cutting induction device of a cutting machine, which can judge whether a product is completely cut or not, and ensures the cutting quality and the cutting efficiency.

The invention provides the following technical scheme:

a cutting induction device of a cutting machine comprises a liftable cutter, wherein a workbench for placing raw materials to be cut is arranged below the cutter; the workbench is provided with a transparent panel, an LED lamp strip is arranged below the panel, and raw materials are placed on the panel. When the cutter cuts the raw materials, the light emitted by the LED lamp strip passes through the transparent panel and then passes through the gaps between the cutting surfaces, and is projected to the upper part of the raw materials, and whether the raw materials are cut or not can be judged by observing the intensity of the light and the intermittent performance of the light through human eyes.

Preferably, the bottom of the cutter is provided with a transparent blade part, the blade part can be made of high-strength transparent materials such as diamond, ceramic glass and the like, an element groove is formed in the blade part, a PCB substrate is embedded in the element groove, and a plurality of photoresistors are welded below the PCB substrate; the upper part of the cutter is connected with a control box, a power module and a controller are arranged in the control box, a cutting status lamp is arranged outside the control box, and the power module is respectively connected with the photoresistor, the controller and the cutting status lamp to supply power for the photoresistor, the controller and the cutting status lamp; the light-sensitive resistor is connected with the controller, and sends a light intensity judging signal to the controller in real time, the controller is connected with the cutting state lamp, and the controller can control the power on and power off of the cutting state lamp. When the cutter does not cut the raw material, the photoresistor in the blade part is positioned in the section of the raw material, so that the light intensity value cannot be detected; when the cutter cuts the raw material, a gap is formed at the bottom of the raw material by the edge part of the cutter, light emitted by an LED below the panel passes through the gap and irradiates the photoresistor, the photoresistor senses abrupt change of light intensity due to the fact that the LED light has a higher light intensity value, the resistance value is rapidly reduced, the change of the resistance value is reflected by the fact that the photoresistor sends high-low level signal conversion to the controller, for example, when the resistance value of the photoresistor is reduced to a certain set value, a low level is sent to the controller, and when the resistance value of the photoresistor is restored to the original resistance value, a high level is sent to the controller; only when each photoresistor detects the light intensity value exceeding the set value, the controller enables the cutting status lamp to be electrified, the cutting surface of the raw material is cut, and the operator is prompted to pass the cutting at the time.

Preferably, a plurality of photoresistors are evenly spaced along the blade portion in the horizontal direction, so that the light intensity change condition of the whole blade portion can be detected, the phenomenon that the photoresistors do not sense the partial non-cutting of raw materials is avoided, and the accuracy of cutting induction is improved.

Preferably, a compressed air channel is arranged in the cutter, one end of the compressed air channel is connected with an external refrigeration type air compressor through a hose, and the other end of the compressed air channel longitudinally penetrates through the blade part of the cutter. The cooling air compressor can provide cooled compressed air for the compressed air channel, and when the cutter cuts the raw materials, the compressed air flows out through the edge part of the cutter, so that the bottom of the raw materials is more easily penetrated by the compressed air, the phenomenon that the cutting surface is stuck continuously is avoided, and the light rays emitted by the LED lamp strip on the workbench are also more easily detected by the photoresistor through the cutting surface; in addition, because of the effect of expansion with heat and contraction with cold, the raw materials contact the refrigerated compressed air and then shrink, and gaps among cutting surfaces of the raw materials are further increased, so that the accuracy of induction results is improved.

Preferably, the compressed air channel comprises a main channel and two branch channels connected with each other, the width of the branch channel is smaller than that of the main channel, the main channel is connected with a hose, the branch channels are positioned at the blade part of the cutter, the blade part comprises a blade tip and blade walls positioned at two sides of the blade tip, and the two branch channels extend to the blade walls. The two branch channels avoid the arrangement of the cutting edge, so that the cutting function of the cutting machine is not affected.

Preferably, a plurality of compressed air flow passages are uniformly arranged in the cutter along the blade part, so that the compressed air flow passages are fully distributed on the blade part, and the cutting and separating effects on raw materials are further improved.

The beneficial effects of the invention are as follows:

1. light emitted by the LED lamp strip passes through the transparent panel and then passes through gaps among the cutting surfaces, and is projected above the raw materials, so that whether the raw materials are cut or not can be judged.

2. The photoresistor, the controller and the cutting status lamp can automatically sense whether the raw material is cut off, manual observation is not needed, and the degree of automation is high.

3. The compressed air channel in the cutter can assist the cutter to cut the raw materials, and the cooled compressed air increases gaps between the cutting surfaces, so that the accuracy of the detection result is improved.
