Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ink grinding equipment, in particular to an ink grinding equipment with automatic switching and buffering. Background Art
[0002] In ink production, the grinding machine is usually the last step in the production process, responsible for further refining the mixed ink raw materials to achieve the desired texture and fineness. Once the grinding is completed, the ink will be directly transported to the finished product tank for storage for subsequent packaging or direct sale.
[0003] However, in the automated production process, the capacity of the finished product can is often fixed. When the finished product can is full, the entire production line needs to be stopped to replace the finished product can or transfer the ink. This intermittent shutdown process not only reduces production efficiency, but may also cause fluctuations in ink quality during the production process. In addition, the shutdown process may also cause confusion in the production rhythm. For ink factories that implement assembly line operations, frequent shutdowns will greatly affect the execution of production plans. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ink grinding device with automatic switching and buffering.
[0005] In order to achieve the above-mentioned purpose, an ink grinding equipment with automatic switching and buffering is designed, including a sand mill, the inlet end of the sand mill is connected to the dispersion kettle through a pipeline, and also includes at least two transfer tanks, the outlet end of the sand mill is connected to the first transfer tank and the second transfer tank through a pipeline and two pipeline branches respectively, and a switching valve is provided on the pipeline branch, the outlet ends of the first transfer tank and the second transfer tank are respectively connected to two independent first tees through pipelines, the two independent first three-way branches are merged and connected to two second tees in pairs, one of the second tees is connected to the pipeline between the dispersion kettle and the sand mill through a pipeline to form a sand grinding circuit, and the other second tee is connected to the finished product tank through a pipeline, and solenoid valves are provided on the four branches of the two first tees.
[0006] Compared with the prior art, the utility model has the following advantages:
[0007] Two transfer tanks are set between the finished product tank and the grinder. The ground products can enter the two transfer tanks in turn to reduce the working pressure, and then flow from the transfer tanks into the finished product tank to achieve continuous production.
[0008] The transfer tank and the grinder form a loop, and the products that are not completely ground in the transfer tank can be returned to the grinder for secondary grinding to ensure product quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1It is a structural schematic diagram of the ink grinding equipment provided by the utility model.
[0010] In the figure: 1. First transfer tank; 2. Second transfer tank; 3. Switching valve; 4. First three-way valve; 5. Second three-way valve; 6. Sand mill; 7. Solenoid valve; 8. Dispersing kettle; 9. Finished product tank. DETAILED DESCRIPTION
[0011] The utility model is further described below in conjunction with the accompanying drawings. The structure and principle of the utility model are very clear to people in the field. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0012] like Figure 1 As shown, this specific embodiment discloses an ink grinding device with automatic switching and buffering, which is used to improve the continuity and efficiency of ink production, reduce the production line downtime caused by full finished product tanks, avoid ink waste, and at the same time form a grinding loop with the grinding machine to perform multiple grindings. The equipment includes a sand mill 6, and the inlet end of the sand mill is connected to a dispersion kettle 8 through a pipeline for receiving the ink to be ground.
[0013] It also includes at least two transfer tanks, namely a first transfer tank 1 and a second transfer tank 2. The outlet end of the sand mill 6 is connected to the first transfer tank 1 and the second transfer tank 2 through a pipeline and two pipeline branches, and a switching valve 3 that can be automatically or manually operated is provided on the pipeline branch to control which transfer tank the ink flows to.
[0014] The outlet of each transfer tank is connected to two independent first tees 4 through pipelines, and each two independent first tees are connected to two second tees 5. One of the second tees is connected to the pipeline between the dispersion kettle 8 and the sand mill 6 through a pipeline, forming a sand milling loop, which can circulate the ink back to the sand mill for secondary grinding to ensure the quality of the ink. The other second tee is connected to the finished product tank 9 through a pipeline to store the ground ink.
[0015] In order to more accurately control the ink flow direction, the four branches of the two first three-way connections are all equipped with remotely controlled solenoid valves 7. These solenoid valves can be automatically opened or closed according to the ink storage conditions of the transfer tanks. When one of the transfer tanks is full, the solenoid valve will switch the ink flow to the other transfer tank. At the same time, the switching valve 3 ensures that the ink no longer flows into the full transfer tank, thereby achieving continuous production without stopping the production line. The solenoid valve 7 can also control the ink in the first transfer tank 1 or the second transfer tank 2 to enter the sand mill again through the sand milling circuit to form secondary or multiple grinding.
[0016] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
