The invention relates to the technical field of tea processing, in particular to a tea impurity removal device, including a feeding plate, which is provided with a felt strip, a plastic roller in contact with the felt strip and a power mechanism for driving the rotation of the plastic roller. An inclined slide rail is arranged below the felt strip, and the plastic roller is provided with a connecting rod mechanism. The sliding rail is provided with a receiving mechanism for receiving sundries. The receiving mechanism can move back and forth in the sliding rail under the action of the connecting rod mechanism to remove sundries. The connecting rod mechanism is connected with a retractable air bag under the action of the connecting rod mechanism. The air bag is provided with an air inlet and an air outlet. The air inlet is provided with a one-way valve and the air outlet is provided with a one-way valve. A one-way valve is arranged, and the air outlet is arranged in the direction toward the feeding plate and the receiving mechanism. The invention can prevent the impurities adsorbed by the plastic roller from falling into the conveyor belt again and mixing with the tea, and at the same time can directly separate the tea from the non-adsorbed impurities without causing the waste of the tea or the secondary impurity removal.

,具体为茶叶除杂装置。
技术介绍
由于茶叶的生产工艺粗放和不卫生,茶叶中常混入灰尘、头发、塑料碎片、铁屑等杂质,造成现在生产处出的茶叶产品很不卫生。针对这些杂质的去除,厂家传统的做法都是租用大量的人工进行挑拣,由于工作人员的认真程度和责任心不同,手工挑拣后的茶叶除杂情况不理想,而且用工量大,厂家成本高。为解决上述问题,中国专利公告号为CN201558744U的一种物料静电除尘除杂机器,包括带进、出料口的密闭罩,置于密闭罩内的物料输送机,物料输送机的出料端设置静电吸附辊及静电吸附板,静电吸附辊及静电吸附板与静电发生器电连接,密闭罩进料口设有产生荷电的水平辊组。该专利需要茶叶与水平辊组摩擦才能产生电荷,在摩擦过程中,会使得大量茶叶被碾碎,降低茶叶品质等其他缺陷。为解决该专利的缺陷,中国专利公告号为CN102294303Bd的茶叶静电除杂机,包括送料板、设置在送料板上的毛毡条和水平设置的塑料辊筒,毛毡条与塑料辊筒摩擦接触,毛毡条下方设置有收纳箱,收纳箱朝机架一侧倾斜。该茶叶静电除杂机通过毛毡条与塑料辊筒接触发生静电,使得塑料辊筒表面吸附的杂物被毛毡条挡住后飘落至收纳箱上,再通过收纳箱排出。茶叶静电除杂机虽然不需要茶叶与塑料辊筒摩擦产生电荷,但值得注意的是,该专利的毛毡条与塑料辊筒接触,塑料辊筒不停的旋转产生静电吸附杂物,杂物被毛毡条挡住后飘落至收纳箱上,当杂物较多时,杂物会推积在收纳箱,则杂物从收纳箱的侧边缘又落在送料板上,不能有效达到茶叶除杂的效果。再有,塑料辊筒静电吸附的杂物都是较轻的,较重的杂物就不容易被吸附在塑 ...
