Drawing of longitudinal arrangement diagram of opening machine

(i) Determine the number of cracks in each section of the rubber roller. The key spacing is one of the basic parameters for longitudinal arrangement. However, when arranging the machine longitudinally, the number of levels of rollers at each level, that is, the number of coatings between two rollers, becomes a more specific basic data. The longitudinal length of the machine can be considered as an integer multiple of the number of levels of rollers at each level. The number of keys of each section of the roller is mainly determined based on the factor that the deflection after roller pressure is too large and does not affect the spinning quality. Experience has shown that the deflection should be less than 0.25. The number of keys of each section of the rubber roller of the cotton spinning opening machine is 6 keys or 8 chains per side. Please determine the number of keys of each section of the roller after investigating conditions similar to the machine or performing calculation tests. After investigating similar machines, the A513 opening machine confirmed that 1 roller has 8 chains. After making a prototype, it was verified through actual measurement that the deflection after pressure was 0.25. (ii) Determine the number of uses between the two middle wall plates. Under the conditions of suspension lifting, the middle fine plate is the lifting guide rail or the additional mechanism near the middle fine plate is the guide rail), the steel collar plate is segmented at the middle fine plate. Therefore, the number of keys between the two fine plates is mainly determined by the rigidity of the steel collar plate. The length of the steel color plate is limited to no more than 1400, so the number of ingots (single-sided) between the two fine plates is 1-18. The A513 type takes 16 pieces, which is twice the number of zippers at each level. (III) Determine the span of the floating support column (middle section) The span of the creel support is often expressed by the number of single-sided keys between the two pillars, which is mainly determined by the rigidity of the longitudinal components of the creel support, generally 16-24 keys (an integer multiple of the number of fasteners per section). The common method is to select the span of the roving frame to be exactly the same as the number of keys between the two fine plates, and incorporate the grid arrangement into the arrangement rules of the fine plates, which is relatively simple in design. However, if the span of the A513 type medium precision plate is 16 spans and the roaming span is also 16 spans, the commonly used number of roaming columns, bracket legs and other components will increase relatively and be wasted, so the span of the A513 type roaming columns is not 16 spans, but 24 spans.
