Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Example
[0032] This embodiment provides a large-scale washing machine automatic washing powder feeding device, such as Figure 1 As shown, the storage hopper 1 is fixedly mounted on the movable frame 2 , and the lower bottom opening of the storage hopper 1 is connected to the lower hopper 3 .
[0033] In this embodiment, Figure 1As shown, the electric box 15, the discharging machine motor 16, the gearbox 17, the feeding pump 10 and the water pump 13 are fixedly installed at the preset positions of the movable rack 2; the electric box 15 is internally encapsulated with a controller and a power supply device, and the controller is respectively signal communication connected to the discharging machine motor 16, the feeding pump 10 and the water pump 13; the controller controls the power on / off of the related elements through the intermediate relay to control the start / stop of the corresponding elements.
[0034] Specifically, the movable rack 2 is a metal connecting rack of welding structure, and the bottom of the movable rack 2 is provided with four universal wheels, based on which the displacement and fixation of the movable rack 2 can be controlled.
[0035] Specifically, the storage hopper 1 is a hollow funnel structure of inverted trapezoidal body with a cover plate arranged at the top surface, which is used for pre-storing the powdery granular solid washing and cleaning materials; the material of the storage hopper 1 is a beige PPR plastic plate (polypropylene engineering waterproof plastic plate); the top opening of the storage hopper 1 is a feeding port, and the bottom opening is a discharging port 7; after the granular solid washing and cleaning materials are added, the cover plate is closed to maintain the relative airtightness inside the storage hopper 1.
[0036] Specifically, the outer side wall of the storage hopper 1 is provided with a vibrator signal communication connected to the controller; based on the pre-setting of the starting condition of the vibrator by the controller, the vibrator is vibrated when the starting condition is reached after the feeding of the storage hopper 1 into the discharging bin 3 is completed, which can shake the granular solid washing and cleaning materials inside the storage hopper 1 to avoid the "wall hanging" of the granular solid washing and cleaning materials, and ensure the thoroughness and accuracy of the feeding.
[0037] In this embodiment, in combination with Figure 1 and Figure 2 , the inside of the discharging bin 3 is provided with a stirrer 4 and a discharging screw 5 from top to bottom, and the discharging screw 5 horizontally penetrates the discharging bin 3 from inside to outside. Figure 1 and Figure 2 , a discharging pipeline 6 is horizontally communicated with the discharging bin 3 and is nested on the outside of the part of the discharging screw 5 protruding from the discharging bin 3; the outside of the discharging pipeline 6 is provided with a discharging port 7.
[0038] Specifically, the discharging bin 3, the stirrer 4, the discharging screw 5 and the discharging pipeline 6 are all made of stainless steel. The granular solid washing and cleaning materials falling into the discharging bin 3 from the storage hopper 1 are shaken by the stirring operation of the stirrer 4 and then fall onto the surface of the discharging screw 5; with the rotation of the discharging screw 5, the granular solid washing and cleaning materials are conveyed out through the discharging port 7 of the discharging pipeline 6.
[0039] Specifically, the discharging machine motor 16 drives the gearbox 17 to control the stirring operation of the stirrer 4 and the rotation operation of the discharging screw 5.
[0040] Specifically, in order to facilitate the quick cleaning of the discharging bin 3, the outer side wall of the discharging bin 3 is provided with a cleaning opening 18.
[0041] In this embodiment, as shown in the figure, a flushing hopper 8 is fixedly arranged below the discharge opening 7, and an annular dripping device 9 is fixedly arranged inside the flushing hopper 8. The bottom of the flushing hopper 8 is connected to a feeding pipeline 11 equipped with a feeding pump 10, and the feeding pump 10 is provided with a valve and an air pipe interface. A water storage tank 12 is connected to the annular dripping device 9 based on a water feeding pipeline 14 equipped with a water pump 13. Figure 1
[0042] Specifically, the flushing hopper 8 is a composite hollow funnel structure of a rectangular cuboid connected to an inverted trapezoidal body from top to bottom. The water for mixing is pre-stored in the water storage tank 12, and the water pump 13 based on the water feeding pipeline 14 extracts the water for mixing into the flushing hopper 8. After the granular solid-state washing and cleaning materials are conveyed into the flushing hopper 8 through the discharge opening 7, the materials are mixed with the water for mixing in the flushing hopper 8. The feeding pump 10 based on the feeding pipeline 11 conveys the mixed materials to the washing equipment. In the case of closing the valve of the feeding pump 10, the air is flushed, which can faster transport the materials and clean the liquid residues in the feeding pipeline.
[0043] Specifically, since the annular dripping device 9 is fixedly arranged inside the flushing hopper 8, the entire inner wall of the flushing hopper 8 is flushed when flushing water, thereby reducing the residue of washing powder and ensuring the thoroughness and accuracy of the feeding.
[0044] Specifically, the water storage tank 12 is provided with a float valve and a liquid level sensor. The liquid level sensor is signal communication connected to the controller and the alarm device. The float valve can control the automatic water discharge of the water storage tank 12. When the water storage tank 12 is short of water, the liquid level sensor inside the water storage tank 12 is triggered to issue an alarm through the alarm device.
[0045] Specifically, the flushing hopper 8 is provided with a full material sensor. Since the full material sensor is signal communication connected to the controller, the flushing hopper 8 is monitored based on the full material sensor to control the start / stop of the feeding pump 10 and the water pump 13.
[0046] In this embodiment, the electric box 15 is externally provided with a display screen and control buttons electrically connected to the controller. The display screen also has a touch control function. Since the controller is signal communication connected to the discharging machine motor 16, the gearbox 17, the feeding pump 10, the water pump 13, the vibrator, the liquid level sensor, and the alarm device, the water flushing time, the water flushing amount, the discharging time, the discharging amount, the working unit time length, and the working time interval can be pre-set by touching the display screen or pressing the control buttons.
[0047] Specifically, the controller receives a signal sent by an external large washing machine, and determines a process start time required by different operations based on the signal.
