Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, and in particular relates to a filling component for liquid coating production. Background Art

[0002] Filling components for liquid coating production are parts of equipment or systems specifically designed to accurately and efficiently fill liquid coatings into containers. In the chemical industry, such equipment is specifically designed to accurately fill prepared liquid coatings into containers, such as cans and barrels, to meet production needs of different scales and market demands. The development of filling technology has greatly improved packaging efficiency and product quality while reducing material waste. Since traditional manual filling methods are not only inefficient but also prone to product contamination, modern filling systems adopt automated or semi-automated operation modes, which can achieve a series of continuous processes from raw material supply to finished product sealing.

[0003] Chinese utility model patent CN221479508U provides a filling device for paint production, including a machine base, a feed hopper and a discharge pipe, the feed hopper and the discharge pipe are respectively arranged at opposite ends of the machine base, and a diverter cylinder is provided in the machine base, and the two ends of the diverter cylinder are respectively connected to the feed hopper and the discharge pipe; the filling device uses a multi-section pipeline formed between the intercepting pipe, the transfer pipe and the diverter cylinder, and uses the height difference structure of the pipeline in the intercepting pipe to perform filling, so as to avoid the accumulation and retention of paint raw materials in the local pipeline. However, in actual use, the device adopts the natural falling method of the material for filling. This method is not only slow, but also easily affected by the fluidity of the material, especially when dealing with paints with higher viscosity, which may lead to reduced production efficiency and the inability to weigh and detect the canned material, resulting in difficulty in accurately controlling the filling amount of the paint, thereby reducing the overall production quality and efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a filling assembly for liquid paint production, which enables liquid paint to be filled efficiently and accurately, thereby improving the production efficiency of filling liquid paint.

[0005] The technical implementation scheme of the present utility model is as follows: a filling component for liquid coating production, comprising a base plate, a platform scale and a storage plate, wherein the base plate is a supporting carrier of the filling component, the platform scale is fixedly mounted on the base plate, the storage plate is mounted on the top surface of the platform scale through a plurality of supporting columns, a tank body for filling is placed on the storage plate, the tank body is a square tank, and the platform scale is used to weigh the weight of the tank body on the storage plate in real time; further comprising: a mounting frame fixedly connected to the base plate, the top of the mounting frame being higher than the tank body; a cylinder fixedly mounted on the top of the mounting frame; a connecting plate fixedly mounted on the telescopic rod of the cylinder, the connecting plate being used to adapt to the tank body The filling port of the tank body; a discharge pipe is arranged between the mounting frame and the connecting plate, and the discharge pipe is retractable; an injection pump is installed on the mounting frame, and the injection pump is used to pump liquid paint; a feeding hopper is connected to the top feed port of the injection pump; a connecting head is provided and connected to the upper end pipe port of the discharge pipe and the discharge port of the injection pump. After placing the tank body on the placement plate so that its filling port is aligned with the connecting plate, the cylinder is activated to drive the connecting plate to dock at the filling port of the tank body. After adding liquid paint to the feeding hopper, the injection pump is used to quickly pump the paint into the tank body through the discharge pipe. At the same time, the platform scale is used to quantitatively fill the paint in the tank body, thereby improving the overall production efficiency of the paint.

[0006] In a preferred embodiment of the present invention, a sealing ring is fixedly provided on the circumference of the lower end surface of the connecting plate docking the tank body filling port, and a sealing ring is provided on the outer wall of the sealing ring. The sealing ring is used to improve the sealing performance when the tank body and the connecting plate are docked, and to avoid unnecessary loss caused by spillage when the connecting plate fills the tank body with paint.

[0007] In a preferred embodiment of the present invention, the connecting plate is also connected to an air outlet valve, which is a one-way valve. The air outlet valve is used to discharge the air inside the tank when the paint is poured, thereby balancing the air pressure inside and outside the tank, so that the paint can be efficiently filled into the tank, thereby improving the filling efficiency of the paint.

[0008] In a preferred embodiment of the present invention, a hinged plate is hinged at the lower end outlet of the discharge pipe, and the hinged plate blocks the outlet of the discharge pipe. A torsion spring is provided between the rotating shaft of the hinged plate and the discharge pipe. The torsion spring acts on the hinged plate to make the hinged plate tightly fit and block the outlet of the discharge pipe. When the paint is filled, the liquid paint in the discharge pipe will overcome the elastic force of the torsion spring to flush open the hinged plate, so that the paint can be smoothly filled into the tank body. After the filling stops, the hinged plate can be blocked at the discharge port of the discharge pipe under the action of the torsion spring, thereby improving the accuracy of paint filling.

[0009] In a preferred embodiment of the present invention, a sealing gasket is also included. A sealing gasket is provided at the pipe mouth where the hinged plate contacts the discharge pipe. The hinged plate is disc-shaped and its edge fits tightly into the lower end pipe wall of the discharge pipe. The sealing gasket is used to further improve the sealing performance of the discharge pipe when no material is discharged.

[0010] In a preferred embodiment of the present invention, a positioning plate is further included. The two side ends of the connecting plate are fixedly connected to the positioning plates. The positioning plates are inclined plates and are limited on the outer walls on both sides of the top of the tank body. The positioning plates are used to limit the placement position of the tank body so that the connecting plate can be accurately aligned with the filling port of the tank body, saving the workload of manually adjusting the filling position of the tank body.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The utility model uses a cylinder to drive the connecting plate to lift and dock the tank, and then uses a filling pump to quickly pour liquid paint into the tank through the discharge pipe. The platform scale monitors the tank weight in real time to ensure that the amount of paint in each tank is accurate, thereby improving product quality and consistency.

[0013] 2. The utility model can help discharge the air in the tank through the one-way air outlet valve, balance the internal and external air pressure so that the paint can flow into the tank more smoothly, speeding up the filling speed. At the same time, the combination of the hinged plate and the torsion spring ensures good sealing performance in the non-filling state. Once the filling starts, it can be quickly opened to ensure the continuity and efficiency of the process.

[0014] 3. The utility model uses a positioning plate to accurately limit the position of the tank body, reducing the need for manual adjustment of the tank body position, reducing labor intensity, and also improving the operational convenience and automation level of the production line.
