In automation technology in precision with blade solution on skin

In automation technology in precision blades rinds solution on zhao zhong da dentsu company welcome to visit exhibition hall 2 e/leather/shoe machinery exhibition hall sewing machine, sewing machine, overlock machine, binding machine, locked stitcher. 。 。 Pick to: this paper tells the story of a DELTA automation products in detail in type XJID3 precision blades rinds on the application of specific applications include measuring the thickness of the automatic segmentation of compensation. Keywords: in automatic shoe machine piece of leather leather machinery 1 introduction shoemaking machinery in our country, was born in the 1980 s. After 20 years of struggle, as China become the world's footwear processing base, shoes machine enterprises completed the startup capital and technology accumulation. In recent years, our country's shoemaking machinery sales growth at a speed of more than 20% every year domestic shoemaking equipment imported only mainland accounts for about 5% of the market share. Machine be leather products enterprises in recent years, with the blade has been widely used in machinery, is the focus of the exhibition equipment of all kinds of leather show recently. This article discusses the type XJID3 precision machine suitable for leather industry with the blade of 4 2 0 mm wide, hard under 8 mm thick, soft leather piece of thin slices, uniform processing. In shoemaking production help, based on the needs of process, requirements for the thickness of the material has a certain size, but the production of leather tannery thickness is often greater than help design size, at this moment, a whole piece of cut should be carried out on help, help give the parts meet the process requirements of uniform thickness. The whole machine structure schematic is shown in figure 1. 2 system structure with the blade for machine is mainly composed of knife sharpener, conveying mechanism, organization, transmission mechanism and part of the dust collection device. 2. 36 meters. Around to avoid after cutting for sheet thickness uneven phenomenon, should be paid attention to when adjusting the upper and lower feed roller to the axis of the upper and lower feed roller with blade mouth remain parallel. 2. By the main fan (2 precipitation unit structure Absorb skin powder) And the auxiliary fan ( Drain powder grinding wheel) The composition, working automatically. 2. 3 knife knife structure have a grinding wheel motor drive, adjusted from grinding organization control door in l2, grinding wheel to move to belt grinding blade mouth. 2. 4 take knife institutions take knife mechanism driven by a motor ring band cycle of rapid rotation, thin knife to slice cutting material. And therefore suitable for will be a whole piece of thin, thin shape software can also be used to help local subdivision, such as before will help the fore part of the local subdivision to put into thermoplastic baotou, simplifying process, reduce the cost. Besides using dedicated mode, a blade can also be of help for the special parts for pills cut. The location of the feed can be made of gauge l. Some blade for machine adopts heavy hammer apparatus. Its blade is always in the job position without the adjustment, in order to observe the edge, most machines panels are equipped with observation window, can be observed through a magnifying glass on the edge. Mouth with blade on the knife total length should be grinded and should be kept flat, no beating and shaking phenomenon. With the sword with a narrow need to change in the future. Tool change, pour the old blade mouth loosen driven after blunt knife wheel, exit the old change new cutter, and tensioning the driven knife wheel again. With a knife tension should be moderate, not too tight or too loose. Take the initiative to the axis of the wheel and the driven knife wheel position are adjustable, the purpose is to make the knife in the correct position during operation, factory have been accurate adjustment, generally should not adjust at will, in order to make sure the machine in good working condition. 2. 5 feed thickness thickness measuring device to adjust the handwheel turns a 1 k precision potentiometer, the change of the thickness of the transition to the change of the resistance, 0 is obtained by voltage transformation 10 v standard signal, into a 0 2000 digital signal, through the highs and lows, the relation between thickness measurement. 3 sets of automation solutions. 3. 1 in automation platform design in automation platform design see table 1. Platform main body by a single technology integration, with homogeneous technology platform solution characteristics. Table 1 in 3 automation platform configuration. Type 2 principle of electrical automation design reference XJID3 precision machine system structure is put forward with the blade of electrical automation requirements, principle of main circuit design as shown in figure 2. Control circuit schematic diagram in figure 3. Figure 2 main circuit principle tutu 3 control circuit schematic diagram 4 conclusion this machine with blade machine adopts LCD touch screen display, has friendly man-machine interface. Slice cutting thickness of digital display accurate, and can set piece of leather, positioning device, with automatic feed tool without adjusting, automatically adjust the clearance between the tool and clamp using a piece of skin of higher precision, wide range frequency conversion stepless speed regulation, feed speed can obtain the ideal piece of leather quality. This solution type XJID3 precision are increased obviously with the blade machine automation technology.
