The present invention relates to the field of tea processing machines, in particular to a weight sensing integrated bruising-sieving machine for automated tea processing.
Bruising is a very important step in initial processing of tea leaves, the result of the bruising step is a deciding factor in the quality of the tea. Traditional tea bruising machines are mainly made up of bruiser bucket, a press lid and a bruiser disc. Tea leaves are poured into the bruiser bucket from above and, using a crank mechanism, driving the bruiser bucket to undergo lateral rotating movement on the bruiser disc. Under the forces from the bruiser bucket, the press lid, the bruiser disc, ribs and the tea leaves itself, tea leaves are rolled into strips along the main vein of the leaves, and at the same time breaking down the leaf cells. The bruised leaves are unloaded through a gate at the center of the bruiser disc, completing the bruising process. Such machine only utilizes an area having the same size as the bottom of the bruiser bucket during operation, therefore utilization rate and the bruising efficiency is low. Furthermore, tea leaves have to be manually removed from the bruiser bucket from above after bruising, which is a cumbersome process. Ashes or residue produced during bruising process need to be filtered at a later stage, making the process even more cumbersome.
The technical problem to be solved by the present invention is: to overcome the aforementioned problem, a weight sensitive integrated bruising-sieving machine for automated tea processing is provided. The structure of the device is sensible, simple, convenient to use, efficient and highly automated, effectively solving the problem of low efficiency and low degree of automation of traditional tea bruising machines.
The technical solution used in the present invention to solve the technical problem is: a weight sensing integrated bruising-sieving machine for automated tea processing, comprising a frame, a bruiser device disposed on the frame, a sieving device and a PLC controller. The bruiser device comprises a bruiser disc, a number of bruiser blades, a first motor mounted on the frame, two pressure adjustment springs, and an adjustment bolt disposed on a first motor main axis. The two pressure adjustment springs are inserted onto the first motor main axis. The bruiser blades are inserted onto the first motor main axis between the two pressure adjustment springs, and is further longitudinally slidably interconnected with a slide rail disposed along the first motor main axis through a sliding block disposed on the bruiser blades. The bruiser disc is mounted on the frame through a number of supporter plates, the bruiser disc having a beveled edge.
The sieving device is disposed below the bruiser device. The sieving device comprises a second motor, a pair of crank mechanisms, a sieve, a sleeve for directing unloading of tea leaves, and an electrically actuated cylinder. A weight sensor for detecting a weight of tea leaves loaded on the sieve is disposed at a connection joint between the crank mechanism and the sieve. The second motor is mounted on a motor stand, and the motor stand is hinged to the frame. An end of the sieve is interdrivably connected to the second motor through the crank mechanism, another end of the sieve is interconnected to an end of the electrically actuated cylinder through the crank mechanism. Another end of the electrically actuated cylinder is hinged to the frame.
In a preferred embodiment, a cylindrical blocker plate is disposed on the frame for prevent tea from spilling out.
In a preferred embodiment, curved rib is disposed on the bruiser disc.
In a preferred embodiment, the sliding block is integrated to the bruiser blades.
In a preferred embodiment, fiber bristles are disposed on the bruiser blades.
In a preferred embodiment, a ring groove is disposed between the bruiser disc and the frame for unloading.
In a preferred embodiment, a humidity sensor is disposed on the sieve.
In a preferred embodiment, the PLC controller is mounted on the frame, the PLC controller is electrically connected to the first motor, the second motor, the weight sensor and the humidity sensor.
In a preferred embodiment, a residue collector is disposed below the sieve.
The advantage of the present invention is: the weight sensing integrated bruising-sieving machine for automated tea processing of the present invention comprises a frame, a bruiser device mounted on the frame, a sieving device and a PLC controller. The bruiser device uses bruiser blades radially disposed above the bruiser disc to replace the bruiser bucket, significantly improving the utilization rate of the bruiser plate and bruising efficiency. Under the effect of the curved ribs and the bruiser blades, tea leaves are pushed towards the inside of the bruiser disc when the first motor is rotating in the clockwise direction. When the first motor is rotating in the opposite direction, the tea leaves move towards the perimeter of the bruiser disc, and fall into the sieving device through the ring groove of the bruiser disc, eliminating the need of removing the tea from the bruiser bucket. The sieving device is driven by the second motor, and has a weight sensor, a humidity sensor and an electrically actuated cylinder disposed. The sieve can automatically pour the sieved tea leaves under the drive of the electrically actuated cylinder, increasing the automation level of the machine. The structure of the device is sensible, simple, convenient to use, efficient and highly automated, effectively solving the problem of low efficiency and low degree of automation of traditional tea bruising machines.
