摘要:本設計涉及一種龍井茶自動炒制機，主要針對市面上龍井茶自動炒制機進行改造?，F有的炒茶機無法實現炒制過程全自動，效率較低。它具有生產效率高，能有效的降低炒制茶葉的勞動強度，能有效提高茶葉批量生產的一致性特點。

　　　傳統炒茶工藝多采用手工炒制，在高溫的炒鍋中，用手掌進行抓、壓、捺、抖等動作，很難保證茶葉的衛生，同時高溫很容易使手受傷很不安全。更大的缺陷在于：手工炒茶的效率很低，在新茶上市季節，炒制任務十分繁重，從而導致工人積勞成疾，茶葉浪費等現象；同時，各階段的時間、溫度和壓力等參數全靠炒茶工人的經驗掌控。

　　　為提高工作效率，降低勞動強度，必須快速推進制茶機械化和自動化。本設計設計的炒制機構能夠完成自動稱重給料，大大減少了手工稱重給料的這一系列過程。此設計炒制機械手采用了壓板機械手和翻版機械手兩個機械手，每個機械手完成自己相應的功能，使茶葉的扁度和里條效果更好。

關鍵詞：自動炒茶機，檔位調節，自動進料裝置，炒制機械手

ABSTRACT:This design is concerned with a longjing tea craft automatic machine, mainly in automatic machine on the market reform longjing tea craft. The existing fry machine can't implement process tea by multiple-refined treatments.and fully automatic, low efficiency. It has high efficiency, the craft can effectively reduce the labor intensity of tea, can effectively improve the tea batch production of the consistency of the characteristics.

　　　Traditional fry tea more use manual process craft, in the high temperature in the fry pan, with the palm to catch, pressure, and shi na, shaking and so on the movement, it is difficult to ensure the health, the high temperature at the same time makes it easy to hand injury is not safe. More of the defects in the: manual fry the efficiency of the tea is very low, in XinCha listed season, the craft is very heavy task, leading to JiLaoChengJi workers, the phenomenon such as tea waste; At the same time, each phase of the time, temperature and pressure in the parameters such as Fried tea workers control experience.

　　　In order to improve the work efficiency and reduce labor intensity, must rapidly advancing tea mechanization and automation. This design design craft of agencies can complete automatic weighing the feeding, greatly reducing the manual feeding this series weighing process. This design using the linking piece by multiple-refined treatments.and manipulator manipulator and counterpart manipulator two manipulator, each manipulator to finish their corresponding function, make tea's degrees and article in effect is better.

Keywords: Automatic machine craft longjing tea, gear adjustment, automatic feeding device, robot craft

選題的意義與目的

　　　為提高炒茶的機械化程度，經過長期的探索與改進，已經有很多關于炒茶機的產品。傳動的手工炒制茶葉，每小時只能炒制60-100g鮮葉，成型茶葉15-25g左右，炒制效率極低。而采用茶葉炒制機每小時可炒制1500g-2000g，成型茶葉375-500g，極大的提高了生產效率。

　　　由于炒鍋溫度在150℃—250℃之間，傳統的手工炒茶設備溫度控制基本靠炒茶工人的經驗來判斷和調節，誤差大，不精確。尤為重要的是，傳統的手工炒茶為了保證茶葉質量，炒茶工人戴上手套后就直接接觸炒鍋進行抓茶葉，壓磨茶葉等一系列動作，工人耐熱能力有限，有時為了安全，需調低炒鍋溫度，使得茶葉質量不好；而有的工人為了保證茶葉質量，長時間在高溫下工作，極其不安全，尤其有時為了趕制茶葉，長時間炒制后產生疲勞打盹，有很大的不安全因素。
