Method and device for obtaining cross-section by rotary cutting of bar material

Abstract

The invention discloses a method for obtaining cross section through bar material rotary-type cutting and a device for obtaining the cross section through the bar material rotary-type cutting. The method adopts a manner that a bar material and a cutter both adopt active rotations; and, when cutting is performed, the rotary bar material and the rotary cutter contact each other to perform the cutting, and then a cross section is formed through the cutting. The device comprises a rotary clamping mechanism, a cut-off end holding and clamping mechanism, a cutter mechanism and a cutting feeding mechanism; the rotary clamping mechanism is composed of a rack body, a rotary clamp head which is rotatable and is disposed on the rack body, a drive motor disposed on the rack body, and a transmission mechanism connected between the drive motor and the rotary clamp head; and the cut-off end holding and clamping mechanism is composed of a rack body and a cut-off holding clamp disposed on the rack body, the cutter mechanism is composed of a drive motor and a cutter, the rotating axis of the cutter and the rotating axis of the bar material are parallel to each other, and the cutter is disposed at a height between the rotary clamp head and the cut-off holding clamp. The bar material rotating and cutter rotating manner is adopted, and the cross section obtained through the cutting can completely satisfy a high-precision analysis detection requirement.

Description

technical field [0001] The invention relates to an industrial processing method and device, in particular to a method and device for obtaining a cross-section through rotary cutting of a bar, and the cut cross-section of the bar is used for camera detection and analysis. Background technique [0002] In the field of product quality analysis and testing, especially in the detection and analysis of the physical shape of the cross-section of the object, the smaller the impact of the cutting tool on the detection cross-section, the better the quality of the detection cross-section, and the more accurate the imaging analysis data information. Especially in the detection of grooved filter rod cross-section in the tobacco industry, because the filter rod is relatively soft, it is easy to deform during the cutting process, and it is difficult to cut a good-quality cross-section to be detected in actual production. [0003] At present, the existing cutting method of fixing the filter...

Problems solved by technology

Especially in the detection of grooved filter rod cross-section in the tobacco industry, because the filter rod is relatively soft, it is easy to deform during the cutting process, and it is difficult to cut a good-quality cross-section to be tested in actual production

[0003] At present, the existing cutting method of fixing the filter rod and rotating the cutter has the following disadvantages: First, during the cutting process of the cutter entering the knife, the blade is easy to squeeze the filter rod to a certain extent, and the cross section of the filter rod will be deformed due to extrusion. Deformation occurs; secondly, during the cutting process, the section will produce burrs and flashes

The above problems will lead to inaccurate analysis of the cross-sectional information of the filter rod, making it difficult to meet the high-precision detection requirements
