Description

Technical Field

[0001] This utility model relates to the field of detergent production technology, specifically to a liquid raw material dispensing device. Background Technology

[0002] Liquid raw material dispensing devices are specialized equipment used in the detergent production industry for the precise distribution of liquid raw materials. Through core components such as measuring cylinders, this device separately delivers various liquid raw materials (such as surfactants, additives, and solvents) to collection tanks according to preset proportions. This ensures accurate proportions of each raw material in subsequent mixing processes, preventing deviations in raw material usage from affecting the cleaning effect, stability, and other properties of the detergent. Suitable for mass production of detergents, it provides crucial assurance for the uniformity of detergent product composition and quality consistency, while also laying a precise raw material foundation for subsequent filling and packaging processes.

[0003] Traditional detergent liquid raw material dispensing devices have significant shortcomings in terms of the accuracy of graduated cylinder dispensing and the prevention of residue buildup. Most devices lack a dedicated structure for handling residue buildup, allowing detergent liquid raw materials (especially some high-viscosity components) to easily adhere to the inner wall of the graduated cylinder, preventing them from flowing completely into the collection bucket. This results in a deviation between the actual dispensed amount and the preset amount, disrupting the raw material ratio in subsequent mixing processes and affecting the quality of the detergent product. While some devices attempt to address residue buildup by manually shaking the graduated cylinder, the lack of a controllable vibration drive mechanism means that the shaking force and frequency rely entirely on experience. This either fails to completely shake off the residue or causes excessive vibration, leading to liquid splashing or cylinder misalignment, which in turn exacerbates the dispensing error. Furthermore, the existing device's support structure design is inadequate, failing to provide stable support for the dispensing components. This makes the components prone to displacement during liquid handling or slight vibrations, further reducing dispensing accuracy. Simultaneously, traditional devices struggle to adapt to detergent liquid raw materials of varying viscosities. When faced with raw materials exhibiting significant viscosity differences, the dispensing effect fluctuates considerably, failing to meet the detergent production demand for "high-precision dispensing and adaptability to raw materials of multiple viscosities." Therefore, we propose a liquid raw material dispensing device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing detergent production equipment lacks a dedicated wall-mounted treatment structure, which fails to meet the demand for high-precision material distribution and compatibility with raw materials of varying viscosities in detergent production.

A rotating disk is movably connected to one lower end of the first motor. A protrusion is fixedly connected to the lower outer wall of the rotating disk.

[0006] In some embodiments, a second bracket is fixedly connected to each of the two outer walls at the upper end of the housing. A fixing plate is fixedly connected to one outer wall of the second bracket. A first limiting block is fixedly connected to one outer wall of the fixing plate. A second motor is fixedly connected to one outer wall at the upper end of the fixing plate. A rotating rod is connected to the lower end of the second motor. A rotating block is fixedly connected to one outer wall at the middle of the rotating rod. A connecting rod is movably connected to one side of the fixing plate. A connecting plate is movably connected to the side of the connecting rod away from the fixing plate. A second limiting block is fixedly connected to one side of the connecting plate. A first return spring is movably connected to one outer wall at the middle of the connecting plate. A roller is connected to one outer wall at the middle of the connecting plate.

[0008] In some embodiments, the limiting ring and the movable block are movably connected to one side of the outer wall of the connecting pipe, and the lower end of the limiting ring is movably connected to the upper outer wall of the second reset spring.

[0009] In some embodiments, a first sphere provided on one side of the inner wall of the first cavity opened in the inner wall of the movable block is correspondingly connected to the upper end of the connecting pipe.

[0010] In some embodiments, a second sphere provided on the inner wall of the second cavity opened in the inner wall of the movable block is correspondingly connected to a first sphere provided on the inner wall of the first cavity.

[0011] In some embodiments, the protrusion at the lower end of the rotating disk is movably connected to the outer wall of one side of the upper end of the movable block.

[0012] In some embodiments, one side of the fixed plate is movably connected to the connecting plate via a connecting rod, and the rollers provided on one side of the connecting plate are correspondingly connected to the rotating block provided on the outer wall of the middle part of the rotating rod.

[0013] This utility model has at least the following beneficial effects: In use, this invention utilizes a suction control structure comprised of a first motor, a rotating disk, a protrusion, a movable block, a connecting pipe, a second return spring, a first ball, and a second ball to automate liquid suction and ensure the airtight protection of raw materials. The first motor drives the rotating disk and the protrusion to rotate. The protrusion periodically presses the movable block, causing it to move longitudinally along the connecting pipe. When the movable block moves downwards, it presses the second return spring. After the protrusion disengages, the movable block rises under the spring's reaction force, using negative pressure to draw liquid from the tank into the movable block through the connecting pipe. The first and second cavities within the movable block cooperate, and the liquid is ultimately discharged through the output pipe, achieving automated liquid suction and dispensing control, avoiding the problems of low efficiency and inaccurate quantity control associated with traditional manual suction. Simultaneously, the first and second balls synchronously raise the guiding channel during suction and reset and close when suction stops, ensuring smooth liquid flow and forming a sealed blockage of the connecting pipe to prevent liquid evaporation or external contamination, thus ensuring the purity and storage quality of the raw materials. The limiting sleeve and limiting ring limit the movement trajectory of the movable block, ensuring a stable and non-deviation-prone suction process. In use, this invention provides a vibrating dispensing structure, consisting of a second motor, a rotating rod, a cam-shaped rotating block, rollers, a connecting plate, a first return spring, and the measuring cylinder, ensuring accurate dispensing and preventing liquid from sticking to the inner wall of the measuring cylinder. Addressing the issue of liquid easily sticking to the inner wall of the measuring cylinder, leading to insufficient dispensing accuracy, the second motor drives the rotating rod to rotate the cam-shaped rotating block. The rotating block, through the rollers, pushes the connecting plate to one side. The connecting plate then returns to its original position under the reaction force of the first return spring, creating a reciprocating motion that synchronously vibrates the measuring cylinder. By adjusting the rotation frequency of the rotating block, the vibration amplitude of the measuring cylinder can be flexibly controlled, shaking liquid stuck to the inner wall to the bottom of the cylinder, ensuring that the liquid is completely delivered to the collection bucket within the error range, significantly improving dispensing accuracy. The fixed plate, the second bracket, and the first limiting block provide stable support for this vibrating structure, preventing component misalignment during vibration and affecting accuracy. This design is suitable for dispensing liquids of different viscosities. In use, this invention simplifies the process and ensures supply by employing an auxiliary structure consisting of an inlet, controller, and housing, which enhances overall ease of operation and guarantees raw material storage. The housing can store liquid raw materials in batches, and the inlet facilitates replenishment without frequent additions, meeting continuous dispensing requirements. The controller centrally drives core components such as the first and second motors, achieving coordinated automated operation of suction, vibration, and dispensing, eliminating the need for dispersed manual operation and reducing labor intensity. The supporting structures for each component (such as the first bracket fixing the first motor and the second bracket fixing the fixing plate) ensure stable overall operation, further improving the continuity and reliability of the dispensing process, making it suitable for batch dispensing scenarios involving liquids such as cleaning agents and reagents.
