Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a ring cutting machine. Background Technology

[0002] A circular cutting machine is a machine that uses the force of machine movement to press a circular die, thereby processing and cutting non-metallic materials. Circular cutting machines are indispensable equipment in some light industries.

[0003] A circular edge cutting machine, disclosed in patent document CN215093892U, includes a machine base, a lifting mechanism, a cutter head, and a support plate. The lifting mechanism is mounted on the machine base, and a crossbeam is mounted on the lifting mechanism. The cutter head is mounted on the crossbeam. A support plate is fixed on the machine base. A horizontal moving mechanism is fixed on the crossbeam, and the cutter head is fixed on the slide of the horizontal moving mechanism. A width-adjusting seat is fixed at the front end of the machine base, and two rotary pressing cylinders are fixed on the two slides of the width-adjusting seat. A pressure plate is fixed to the output shaft end of each rotary pressing cylinder. A support plate cleaning mechanism is provided at the rear end of the machine base. The cutter head is a circular cutter disc. This comparative technical solution uses the width-adjusting seat and the rotary pressing cylinders to drive the two pressure plates, smoothing and flattening the material, thus making the cutter head cut the material more neatly and avoiding unevenness that affects the cutting effect. The support plate cleaning mechanism cleans debris from the support plate.

[0004] However, the above-mentioned mechanism has the following problems: First, it cannot automatically feed materials, and each feeding and unloading requires manual intervention from below the die, which is dangerous; second, the waste material after cleaning will accumulate on the cutting machine, which will affect the feeding and unloading of the cutting machine over time, and manual cleaning is required before it can continue to work, affecting production efficiency.

[0007] Furthermore, the conveyor table 19 is provided with more than two support shafts 21 below it. The support shafts 21 are supported on the support feet 22 by bearings and are equipped with rollers 24 that cooperate with the roller frame 1 at both ends. The top of the conveyor table 19 is provided with a connecting plate 20 that is fixed to the output end of the conveying cylinder 11.

[0008] Furthermore, the inner side of each roller 24 is provided with a side baffle 23 to prevent deviation.

[0009] Furthermore, the brush roller 18 is supported on the adjusting plate 5 by bearings, and the adjusting plate 5 slides up and down within the limiting plates 2 on both sides of the base 9, and is powered by the electric push rod 4 on the electric push rod bracket 3.

[0010] Furthermore, a filter plate 16 is provided above the groove in the base 9.

[0011] Furthermore, the inner side of the gantry frame 12 is provided with a cleaning nozzle 15, which is powered by the air pump 6 below.

[0012] This utility model has the following advantages: First, it allows for loading and unloading outside the die, avoiding personnel injury, and allows materials to be automatically fed into the area below the die; second, the waste material is concentrated in the groove in the center of the base, preventing waste material from accumulating on the back plate and affecting processing; third, it is equipped with a filter plate, which allows small waste material to enter the area below the base and be cleaned after a long period of time, while larger waste material is cleaned after the filter plate is full, thus improving production efficiency.
