Summary of the invention
Object of the present invention is just to provide a kind of kneading machine of automatic collection tea amount signal, accurately feeds intake to tea twisting machine.
For realizing above object, the technical solution used in the present invention is: a kind of automatic tea kneading machine, comprise for receive batch charging mechanism throw in tealeaves knead dish, be furnished with above the card of kneading dish vertically arrange knead cylinder, knead on cylinder and be provided with gland, described gland is provided with the sensor for gathering tea amount, control unit receives and the tealeaves injected volume signal of processes sensor collection, and control unit exports control signal and controls valve opening, the closing motion of batch charging mechanism.
Compared with prior art, the present invention possesses following technique effect: by the sensor setting for detecting tea amount at gland, this sensor can detect the injected volume information of tealeaves accurately, and export the injected volume signal of detection to control unit, thus automatically control to throw in tealeaves to kneading in dish, and then guarantee the accuracy of tealeaves injected volume, this automatic tea kneading machine automaticity is high.
Detailed description of the invention
Composition graphs 1 to Fig. 3, is described in more detail the present invention:
A kind of automatic tea kneading machine, comprise for receive batch charging mechanism throw in tealeaves knead dish 10, be furnished with above the card of kneading dish 10 vertically arrange knead cylinder 20, knead on cylinder 20 and be provided with gland 30, described gland 30 is provided with the sensor 40 for gathering tea amount, control unit receives and the tealeaves injected volume signal of processes sensor 40 collection, and control unit exports control signal and controls valve opening, the closing motion of batch charging mechanism.
Sensor 40 is arranged on gland 30, the tea amount that very convenient detection is kneaded in cylinder 20, namely knead the tea amount on dish 10, when tea amount is not enough, batch charging mechanism continuation case is kneaded dish 10 and is thrown in tealeaves, when sensor 40 detects that tea amount is suitable, sensor 40 exports tea amount signal to control unit, control unit controls batch charging mechanism to be stopped feeding intake to kneading dish 10, this tea twisting machine can realize the automation that tea amount detects, and then realize the automation that tealeaves feeds intake, greatly can improve the efficiency of Tea Production.
As preferred version of the present invention, described sensor 40 is range sensor, gland 30 is provided with the cavity holding sensor 40, at the bottom of the chamber of this cavity, 301 is elastic sheet, at the bottom of chamber, 301 are outstandingly downwards arranged on the lower capping of gland 30, at the bottom of sensor 30 acquisition cavity 301 displacement variable signal and export on control unit.When batch charging mechanism to knead dish 10 deliver material time, when the signal of tea amount arrives a certain amount of, tealeaves makes the elastic sheet generation deformation of at the bottom of chamber 301, the test side being positioned at the sensor 40 of this chamber can detect the deformation variable quantity of at the bottom of chamber 301, and this variable signal is transferred on control unit, control unit exports control signal and is used for the valve closing of batch charging mechanism, thus stop feeding intake to kneading in dish 10, sensor 40 is arranged to said structure, can implement accurately to detect tea amount, improve the automaticity of kneading machine.
The described outer wall kneading cylinder 20 prolongs radial direction armed lever 21 is set, the suspension end of armed lever 21 and one end of rotating crank 50 hinged, the other end of rotating crank 50 and the upper end of rotating shaft 60 are connected, axial, between armed lever 21 and rotating crank 50 the jointed shaft of rotating shaft 60 is positioned at vertical direction, and rotating shaft 60 rotary type is arranged on brace table 61;
Be arranged on knead on dish 10 owing to kneading cylinder 20 rotary type, and how the signal of the sensor 40 rotated is drawn, do not hinder the normal rotation of kneading cylinder 20, therefore, if straight and sensor 40 is connected and leads to control unit by holding wire, holding wire is certain to produce the rotation of kneading cylinder 20 interfere, rotate to kneading cylinder 20 interference produced for avoiding holding wire, be positioned at the place of being rotationally connected of rotating shaft 60 and brace table 61 and armed lever 21 to arrange with rotating shaft winch 50 articulated position place and be respectively arranged with first, second conduction brush ring 70, 80, holding wire one end for transmission sensor 40 is conducted electricity brush ring 70 by brace table 61 and first and is connected, first conduction brush ring 70 and second is conducted electricity between brush ring 80 and is communicated with by holding wire, second conduction brush ring 80 is communicated with sensor 40 by holding wire.
Particularly, first, second conduction brush ring 70,80 described includes slip ring and brush, first slip ring 71 of the first conduction brush ring 70 is fixed on the axle head of rotating shaft 60, and the first brush 82 of the first conduction brush ring 70 is fixed on brace table 61, the outer wall of the first brush 82 and the first slip ring 81 against;
Axle head on the jointed shaft 51 that second slip ring 81 of the second conduction brush ring 80 is fixed on rotating crank 50, the second brush 82 of the second conduction brush ring 80 is fixed on armed lever 21, the outer wall of the second brush 82 and the second slip ring 81 against;
Holding wire is connected with the first brush 72, is communicated with between the first slip ring 71 with the second conducting slip ring 81 by holding wire, and the second brush 82 is communicated with sensor 40 by holding wire;
Holding wire is accessed by control unit, brace table 61 is offered the first through hole 61a, holding wire is introduced by the first through hole 61a and is connected with the first the first brush 72 conducting electricity brush ring 70, in the process that rotating shaft 60 is rotated at brace table 61, second is offered respectively in rotating shaft 60 and on rotating crank 50, third through-hole 60a, 50a, power line is by second, third through-hole 60a, 50a introduces, one end and first slip ring 71 of holding wire are connected, the other end and second slip ring 81 of power line are connected, armed lever 21 is offered fourth hole 21a, signalization line in fourth hole 21a, one end of holding wire is fixed on the second brush 82, the other end of power line is communicated with sensor 40, above-mentioned connected mode, when kneading machine startup work, knead cylinder 20 in the process of rotating, holding wire can not produce the rotation of kneading cylinder 20 interferes.
