    摘要:

    針對(duì)目前我國竹筍剝皮機(jī)械化程度低的問題,設(shè)計(jì)一種刀削結(jié)合滾動(dòng)摩擦進(jìn)料竹筍剝皮機(jī)。根據(jù)竹筍物理特性參數(shù)和人工剝筍原理,對(duì)竹筍剝皮過程進(jìn)行力學(xué)與運(yùn)動(dòng)學(xué)分析,確定了影響剝皮效率、損傷率和剝凈率的主要因素為刀片安裝傾角、剝皮輥轉(zhuǎn)速以及滾筒與剝皮輥軸心高度差,在此基礎(chǔ)上,給出了竹筍剝皮機(jī)關(guān)鍵部件的設(shè)計(jì)依據(jù)。為獲得樣機(jī)最佳試驗(yàn)物料,以竹筍長度、基部直徑作為試驗(yàn)因素進(jìn)行單因素試驗(yàn),確定長度為300~320mm、基部直徑為29~32mm的竹筍作為剝皮機(jī)正交試驗(yàn)物料樣本。利用Design-Expert軟件設(shè)計(jì)三因素三水平正交試驗(yàn),并結(jié)合實(shí)際工作情況確定最優(yōu)參數(shù)組合,結(jié)果表明:當(dāng)?shù)镀惭b傾角為30.12°、剝皮輥轉(zhuǎn)速為229.18r/min、滾筒與剝皮輥軸心高度差為15.43mm時(shí),筍肉損傷率為6.81%,筍皮剝凈率為94.59%。在該條件下開展驗(yàn)證試驗(yàn),得到損傷率、剝凈率分別為7.10%、93.22%,與優(yōu)化參數(shù)基本一致,滿足剝筍要求。

    Abstract:

    A bamboo shoots peeling machine with rolling friction feeding based on knife-cutting method was designed according to the low degree of mechanization of bamboo shoots peeling in China. Based on the physical characteristic parameters of bamboo shoots and the principle of artificial bamboo shoots peeling, the force and movement analysis in the peeling process were described in detail, and the main factors affecting peeling efficiency, damage rate, no-hell rate were identified as the blade installation angle, the rotation speed of the peeling roller, the axis height difference between the roller and the peeling roller. On this basis, the design principle of the key components and the bamboo shoots peeling machine were given. In order to obtain the best experimental materials for the prototype experiment, single factor experiment was carried out with the length and base diameter of bamboo shoots as experimental factors, and the length from 300mm to 320mm and the base diameter from 29mm to 32mm were selected as orthogonal experimental materials samples for the bamboo shoots peeling machine. The Design-Expert software was used to design the orthogonal experiment and determine the optimal parameter combination of peeling quality according to the actual work situation. The results showed that when the blade installation angle was 30.12°, the rotation speed of the peeling roller was 229.18r/min, the axis height difference between the roller and the peeling roller was 15.43mm, the damage rate of bamboo shoots was 6.81%, and the no-shell rate was 94.59%. The verification experiment was carried out under these conditions, and the results showed that the damage rate and no-shell rate were 7.10% and 93.22%, respectively, which were basically consistent with the optimized parameters. This product can meet the requirements of bamboo shoots peeling.
