Description

Technical Field

[0001] The utility model relates to the field of material feeding devices, in particular to a quantitative feeding device for cleaning agents. Background Art

[0002] Cleaning agents cover a wide range and come in various types, including two major categories: inorganic cleaning agents and organic cleaning agents. Simply put, the difference between organic cleaning agents and inorganic cleaning agents is that organic cleaning agents are made of carbon-containing compounds, while inorganic cleaning agents are made of carbon-free compounds, so they belong to inorganic substances. Among them, aqueous cleaning agents are formulated from surfactants (such as sodium alkylbenzene sulfonate, sodium lauryl sulfate) and various additives (such as sodium tripolyphosphate), auxiliary agents. When washing the dirt on the surface of an object, they can reduce the surface tension of the aqueous solution and improve the decontamination effect.

[0003] During the recycling and cleaning process of lunch boxes, it is necessary to quantitatively add cleaning agents to the cleaning solution to improve the effect of lunch box recycling and cleaning. At present, the work of putting in cleaning agents requires manual weighing and putting in, which increases the workload of operators and also reduces the feeding efficiency of cleaning agents.

[0022] The cleaning agent quantitative discharging device of the utility model will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the utility model are shown. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the beneficial effects of the utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the utility model.

[0023] The present utility model will be described more specifically by way of example with reference to the accompanying drawings in the following paragraphs. The advantages and features of the present utility model will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model.

[0024] As Figures 1 to 3 shown, an embodiment of the present utility model provides a device for quantitatively dispensing a cleaning agent, which includes a base 1, a dispensing tray 2, a hopper 3, and a rotating motor 4.

[0025] Specifically, the dispensing tray 2 is rotatably mounted on the base 1. Two material cavities 5 with adjustable spaces are symmetrically arranged on the dispensing tray 2, and the material cavities 5 sequentially perform material taking and discharging through rotation.

[0026] The hopper 3 is arranged on the base 1, and the material cavity 5 is docked with the hopper 3 through rotation to take materials.

[0027] The rotating motor 4 is fixedly mounted on the base 1, and the rotating motor 4 is in transmission connection with the dispensing tray 2.

[0028] In this embodiment, when the material cavity 5 is in communication with the hopper 3, the cleaning agent in the hopper 3 enters the material cavity 5. Subsequently, under the drive of the rotating motor 4, the opening directions of the two material cavities 5 are interchanged, so that the material cavity 5 filled with the cleaning agent faces the equipment to be added, and the cleaning agent in the material cavity 5 is poured into the equipment to be added, completing the dispensing operation of the cleaning agent. At the same time, the hopper 3 performs a feeding operation on the other material cavity 5.

[0029] In a specific embodiment, the rotating motor 4 is a servo motor. The servo motor can control the speed and has very accurate position accuracy. It can convert the voltage signal into torque and rotational speed to drive the controlled object. The rotational speed of the rotor of the servo motor is controlled by the input signal and can respond quickly. In an automatic control system, it is used as an actuator and has characteristics such as a small electromechanical time constant and high linearity, and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0030] The rotating motor 4 being a servo motor can control the rotation angle and rotation frequency of the dispensing tray 2. For example, it rotates 180° each time to complete the switching between the loading and unloading of the cleaning agent. And the cleaning agent is dispensed once every 10 minutes, which can realize the timed and quantitative dispensing of the cleaning agent. Among them, the specific dispensing speed of the cleaning agent can be determined according to the actual on-site situation.

[0031] It should be noted that the space of the material cavity 5 is adjustable, that is, the size of the material cavity 5 can be adjusted to change the loading amount of the cleaning agent in the material cavity 5, thereby realizing the quantitative delivery of the cleaning agent. Among them, the loading amount of the cleaning agent is set according to the actual cleaning needs. When the delivery amount of the cleaning agent does not change, there is no need to adjust the loading amount of the cleaning agent.

[0032] Furthermore, a sealing ring 6 is fixedly arranged on the base 1, and the sealing ring 6 is in fitting and sliding contact with the outer side wall of the delivery tray 2. A material taking port 7 and a discharging port 8 are symmetrically arranged on the sealing ring 6.

[0033] Specifically, the material taking port 7 is communicated with the hopper 3. When the material cavity 5 is communicated with the material taking port 7, the cleaning agent in the hopper 3 passes through the material taking port 7 and enters the material cavity 5. After the delivery tray 2 rotates 180°, the material cavity 5 loaded with the cleaning agent is vertically oriented towards the device to be added, and the cleaning agent in the material cavity 5 is poured into the device to be added from the material cavity 5, completing the material delivery operation.

[0034] Among them, the sealing ring 6 is of an annular structure, and the inner wall of the sealing ring 6 is in close fit with the side circumferential surface of the delivery tray 2. When the material cavity 5 of the delivery tray 2 is communicated with the material taking port 7, the cleaning agent in the hopper 3 passes through the material taking port 7 and enters the material cavity 5. During the rotation of the delivery tray 2 from the material taking port 7 to the discharging port 8, the inner wall of the sealing ring 6 seals the material cavity 5, avoiding the leakage of the cleaning agent. When the material cavity 5 is communicated with the discharging port 8, the cleaning agent in the material cavity 5 is discharged from the discharging port 8, completing the delivery operation of the cleaning agent.

[0035] Furthermore, an adjusting piece 9 for adjusting the material storage space is movably arranged in the material cavity 5, and the adjusting pieces 9 are commonly threadedly connected with a synchronous adjusting screw rod 16, and the synchronous adjusting screw rod 16 is rotatably installed on the delivery tray 2.

[0036] Specifically, the synchronous adjusting screw rod 16 includes a driving rod 10 and driving threads 11, the driving threads 11 are arranged at both ends of the driving rod 10, and the driving threads 11 at both ends of the driving rod 10 have opposite helix directions.

[0037] In this embodiment, the adjusting piece 9 is slidably arranged along the length direction of the material cavity 5. For example, the material cavity 5 is provided with a positioning chute (not shown) along its length direction, and the adjusting piece 9 is slidably installed in the positioning chute (not shown) through a sliding piece, so that the adjusting piece 9 can move along the length direction of the material cavity 5.

[0038] When it is necessary to adjust the space of the material cavity 5, rotate the synchronous adjustment screw rod 16. The adjustment piece 9 threadedly connected to the synchronous adjustment screw rod 16 cannot rotate with the synchronous adjustment screw rod 16 due to the limiting effect of the inner wall of the material cavity 5. The adjustment piece 9 can only move along the length direction of the synchronous adjustment screw rod 16, and the moving direction of the adjustment piece 9 is controlled by the forward or reverse rotation of the synchronous adjustment screw rod 16. During the movement of the adjustment piece 9, the space adjustment of the material cavity 5 can be realized.

[0039] It should be noted that the rotation of the synchronous adjustment screw rod 16 has a certain resistance. After the position adjustment of the adjustment piece 9 is completed, without external force to rotate the synchronous adjustment screw rod 16, the adjustment piece 9 stably maintains its current position, thereby ensuring the constancy of the material space and realizing the stable quantitative delivery of the cleaning agent.

[0040] To facilitate the rotation of the synchronous adjustment screw rod 16, an adjustment knob 12 is fixedly arranged in the middle of the driving rod 10, and an adjustment installation cavity 15 matching the adjustment knob 12 is arranged on the delivery tray 2.

[0041] In addition, in order to visually observe the size of the material cavity 5, a transparent window 13 is arranged on the side wall of the material cavity 5, and a scale marking 14 is arranged on the transparent window 13.

[0042] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0043] The present utility model adjusts the capacity of the cleaning agent by changing the size of the material cavity, and then realizes the loading and delivery of the cleaning agent through the rotation of the delivery tray, thereby realizing the quantitative delivery of the cleaning agent, without the need for manual weighing and delivery, greatly reducing the cost of cleaning agent delivery.

[0044] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
