Description

Technical Field

[0001] The present invention belongs to the technical field of wet impregnation equipment, and particularly relates to an automatic glue mixing and automatic cleaning system and a using method thereof. Background Art

[0002] In the production of wet impregnation equipment, the raw materials (glue solution) for production are in a state of continuous consumption. Workers need to continuously supplement the glue solution. Moreover, during the production process, the solvent in the glue solution keeps volatilizing. As the production progresses, the composition of the glue solution prepared according to the process parameters also changes, which is not conducive to the consistency of the products. In addition, due to manual glue mixing, there will also be differences in each ratio. The above factors are all uncertain factors in product production.

[0003] After each production is completed, it is necessary for personnel to manually clean the equipment to remove the residual glue in the glue tank of the equipment. Usually, the cleaning materials used have a certain smell and corrosiveness, and the working conditions are relatively harsh for workers.

[0004] In industrial production, there are cases where two or more products are produced in a day, which increases the intensity of manual glue mixing and the efficiency is also very low.

[0005] Currently, in view of the above production conditions, there is a lack of an efficient, intelligent and stable technical means to solve the above problems. Therefore, there is an urgent need for an automatic glue mixing and automatic cleaning system and a using method thereof to solve. Summary of the Invention

The liquid outlet end of Valve 4 is connected to the liquid inlet end of the dipping device of the production line.

[0050] A usage method of an automatic glue mixing and automatic cleaning system, using the above automatic glue mixing and automatic cleaning system, includes the following steps:

[0051] Store the glue liquid raw materials in the glue liquid barrel and store the solvent raw materials in the solvent barrel;

[0052] Prepare glue liquid A and glue liquid B successively in the glue mixing kettle, and store glue liquid A in the glue storage kettle;

[0053] Circulate glue liquid B between the glue mixing kettle and the dipping device of the production line to produce product B, and replenish the consumed glue liquid B in the glue mixing kettle;

[0054] Let glue liquid B enter the glue storage kettle, and at the same time circulate glue liquid A between the glue mixing kettle and the dipping device of the production line to produce product A, and replenish the consumed glue liquid A in the glue mixing kettle;

[0055] After production, discharge glue liquid A and glue liquid B into the waste liquid barrel. Use the solvent to pass through the glue mixing kettle, the specific gravity sensor and the liquid level sensor, the glue storage kettle and the dipping device of the production line in sequence and then return to the glue mixing kettle, and then discharge from the glue mixing kettle into the waste liquid barrel.

[0056] As an alternative implementation, a quantitative amount of glue raw materials and solvent raw materials are input into the glue mixing kettle according to the ratio of glue solution A. The stirring system and jacket heating system in the glue mixing kettle are started to prepare glue solution A and store it in the glue mixing kettle. A specific gravity sensor and a liquid level sensor are used to detect the specific gravity and volume of glue solution A;

[0057] The glue solution A in the glue mixing kettle is pumped into the glue storage kettle for storage.

[0058] As an alternative implementation, a quantitative amount of glue raw materials and solvent raw materials are input into the glue mixing kettle according to the ratio of glue solution B. The stirring system and jacket heating system in the glue mixing kettle are started to prepare glue solution B and store it in the glue mixing kettle. A specific gravity sensor and a liquid level sensor are used to detect the specific gravity and volume of glue solution B;

[0059] The glue solution B is pumped into the dipping device on the production line to produce product B, and the glue solution B circulates between the dipping device on the production line and the glue mixing kettle;

[0060] The specific gravity and volume of the glue solution B are detected by a specific gravity sensor and a liquid level sensor, and glue raw materials and solvent raw materials are replenished into the glue mixing kettle according to the ratio of glue solution B;

[0061] After the production of product B is completed, all the glue solution B in the dipping device on the production line is recycled into the glue mixing kettle, all the glue solution A in the glue storage kettle is pumped into the dipping device on the production line, all the glue solution B in the glue mixing kettle is pumped into the glue storage kettle, and the glue solution A in the dipping device on the production line circulates between the glue mixing kettle and the dipping device on the production line to produce product A;

[0062] The specific gravity and volume of the glue solution A are detected by a specific gravity sensor and a liquid level sensor, and glue raw materials and solvent raw materials are replenished into the glue mixing kettle according to the ratio of glue solution B.

[0063] As an alternative implementation, after all the glue solution A is recycled into the glue mixing kettle after the product production is completed, all the glue solution A is pumped into the waste liquid bucket. After the glue solution B in the glue storage kettle returns to the glue mixing kettle through the dipping device on the production line, the glue mixing kettle pumps all the glue solution B into the waste liquid bucket;

[0064] The solvent in the solvent bucket enters the glue mixing kettle, the glue storage kettle, and the dipping device on the production line in sequence and then returns to the glue mixing kettle, and then the glue mixing kettle pumps it into the waste liquid bucket;

[0065] The solvent in the solvent bucket is passed through a specific gravity sensor and a liquid level sensor for cleaning and then enters the glue mixing kettle, and then the glue mixing kettle pumps it into the waste liquid bucket.

[0066] A method for using an automatic glue mixing and automatic cleaning system specifically includes the following steps:

[0067] 1. Mix glue solution A

[0068] Calculate the volume of Adhesive A according to the production plan, input the data into the glue mixing system, and the system calculates the volume of the glue and the volume of the solvent based on preliminary calculations, and then measures.

[0069] Pump 1 and Pump 2 input the corresponding amounts of liquid into the glue mixing kettle according to the data. At this time, Valve 1 is opened, the jacket heating system of the glue mixing kettle is turned on, and the stirring is turned on. When the input of the corresponding glue and solvent is completed, Pump 1, Pump 2, and Valve 1 are closed. The specific gravity sensor detects whether the specific gravity parameter of Adhesive A is consistent with the preset value. If not, the system can obtain the corresponding volume according to the liquid level detected by the liquid level sensor, and then calculate the amount of material (solvent or glue) to be added according to the specific gravity difference. Stop the above operations until the detected value of the hydrometer is consistent with the preset value.

[0070] 2. Transfer Adhesive A for standby

[0071] Transfer the glue from the glue mixing kettle to the glue storage kettle. Pump 4 works, Valve 5 is opened, the jacket heating system works, and the stirring system works. When the liquid level sensor of the glue mixing kettle detects the lowest liquid level, Pump 4 stops working and Valve 5 is closed, and the transfer of Adhesive A is completed.

[0072] 3. Prepare Adhesive B

[0073] The glue mixing process is the same as that of Adhesive A.

[0074] 4. Produce Product B

[0075] The glue mixing kettle transports Adhesive B to the dipping device of the production line. Pump 3 and Pump 4 work, and Valve 3 is opened. At this time, Adhesive B will circulate between the glue mixing kettle and the dipping device of the production line all the time, and the specific gravity sensor detects the specific gravity of Adhesive B throughout the process. When the detected specific gravity changes, the glue mixing system automatically starts to compensate for the solvent (because there is often solvent volatilization during the production process).

[0076] 5. Produce Product A

[0077] When the production of Product B is completed, Pump 4 is closed, Valve 3 is closed, and Pump 3 continues to work to completely recover the Adhesive B in the dipping device of the production line back to the glue mixing kettle. When the dipping device of the production line detects that the glue recovery is completed, at this time, Pump 5 works, Valve 4 is opened, and the Adhesive A in the glue storage kettle is transported to the dipping device of the production line. After the transportation is completed, Pump 5 stops and Valve 4 is closed, and the production line produces Product A. At this time, the glue mixing kettle remixes Adhesive A. When the glue mixing kettle has prepared Adhesive A, at this time, Pump 3 and Pump 4 work, and Valve 3 is opened, and the glue starts to circulate.

[0078] 6. Production completed, drain the glue

[0079] After the production of Product A is completed, Pump Four is closed, Valve Three is closed, and Pump Three continues to work to completely recover the B glue liquid in the dipping device of the production line back to the glue mixing kettle. When the dipping device of the production line detects that the glue liquid recovery is completed, Pump Three is closed. At this time, Pump Four works and Valve Six is opened, and the glue liquid is discharged into the waste liquid bucket.

[0080] 7. Start the automatic cleaning function

[0081] Pump One works and Valve One is opened, and the solvent is input into the glue mixing kettle. When the liquid level sensor detects that the solvent reaches the preset height, Pump One stops working and Valve One is closed. The stirring systems of both kettles work simultaneously. At this time, Pump Four works and Valve Five is opened, and the solvent enters the glue storage kettle from the glue mixing kettle. Pump Five works and Valve Four is opened, and the solvent enters the dipping device of the production line from the glue storage kettle. Pump Three is opened, and the solvent returns to the glue mixing kettle again, and the solvent circulates and cleans in the whole system. When the cleaning time reaches the preset time, Valve Five is closed and Valve Six is opened, and the waste liquid is finally discharged into the waste liquid bucket. After the cleaning is completed, all pumps are closed and valves are closed.

[0082] 8. Automatic cleaning function of key detection devices

[0083] Pump One works and Valve Two is opened, and the solvent flushes the specific gravity sensor and the liquid level sensor, and the waste liquid is directly discharged through Pump Four and Valve Six. Thus, the whole work is completed.

[0084] Among them, Pump One, Pump Two, Pump Three, Pump Four and Pump Five are all selected as metering pumps.

[0085] The following is one of the application examples of the present invention:

[0086] Step 1: Input the specific gravity parameter ρ of the glue liquid A required for Product A according to the production plan A , usage amount V A

[0087] Based on the existing database, the system internally stores the specific gravity parameter of the original glue liquid itself, the specific gravity parameter of the solvent itself, and the required specific gravity parameter ρ g / cm of the glue liquid to be prepared combined with the system input 3 , usage amount V, and calculates the volume of the glue liquid and the volume of the solvent that need to be input into the glue mixing kettle.

[0088] For example, given the density of the original glue liquid ρ1 g / cm 3 , the required volume of the original glue liquid V1, the density of the solvent ρ2 g / cm 3 , the specific gravity (density) of the glue liquid to be prepared ρ g / cm 3 , the volume of the solvent V2, from Formula 1, (ρ1 * V1 + ρ2 * V2) / (V1 + V2) = ρ A *V A , Formula 2, V1 + V2 = V; according to this formula, the system can calculate the data of V1 and V2 respectively.

[0089] Step 2: Inject the original glue solution and solvent into the glue preparation kettle

[0090] Pump 1 and Pump 2 respectively input corresponding volumes of liquid into the glue mixing kettle. At this time, the stirring system of the glue mixing kettle works and the jacket heating system works.

[0091] Step 3: The specific gravity sensor performs data detection.

[0092] A specific gravity sensor is installed in the glue mixing kettle. The sensor can detect the liquid specific gravity value ρ3 in real time. At this time, there may be a slight difference between the detected specific gravity value ρ3 and the specific gravity parameter ρ of the glue liquid to be mixed input by the system. When ρ3>ρ, pump one will inject a small amount of solvent. When ρ3<ρ, pump two will inject a small amount of original glue liquid until ρ3=ρ, and the glue mixing work is completed.

[0093] Step 4: Glue liquid A is transferred from the glue preparation kettle to the glue storage kettle.

[0094] The glue liquid is transferred from the glue preparation kettle to the glue storage kettle, pump four works, valve five is opened, the jacket heating system works, and the stirring system works. When the glue preparation kettle liquid level sensor detects the lowest liquid level, pump four stops working, valve five is closed, and the transfer of product A glue liquid is completed.

[0095] Step 5: Input the specific gravity parameter ρ of glue solution B required for product B according to the production plan B , usage V B .

[0096] The glue preparation process is the same as that of glue solution A.

[0097] Step 6: Product B production

[0098] The glue preparation kettle transports glue liquid B to the production line's glue dipping device. Pump four works and valve three opens. At this time, glue liquid B will be input into the glue tank of the production line until the glue liquid reaches the predetermined liquid level in the teaching tank. The volume of the glue tank is V-trough. At this time, pump three also starts working and the glue liquid begins to circulate. In order to ensure that the liquid level in the glue tank of the production line remains unchanged, the flow of pump three needs to be adjusted at any time, and the flow of pump four is a fixed value.

[0099] For example, the flow rate per minute of pump four is X1, the flow rate per minute of pump three is X2, and the consumption per minute of the production line is X3, then X1-X2=X3. When the speed of the production line increases, X3 will also increase accordingly, and the value of X2 will decrease accordingly.

[0100] During the entire production process, the specific gravity sensor continuously detects the specific gravity of glue liquid B. When a change in specific gravity is detected, the glue preparation system automatically starts to compensate for the solvent (because solvent volatilization often occurs during the production process).

[0101] For example, the volume of the glue tank is V 槽 , the remaining glue volume V in the glue preparation kettle 釜 , specific gravity sensor detection value ρ测 , the adhesive solution B requires a specific gravity (density) of ρ B , then the solvent volume V needs to be compensated 补 , from the formula ((V 槽 + V 釜 ) * ρ 测 + V 补 * ρ2) / (V 槽 + V 釜 + V 补 ) = (V 槽 + V 釜 + V 补 ) * ρ B .

[0102] Step Six: Production of Product A

[0103] After the production of Product B is completed, Pump Four is closed, Valve Three is closed, and Pump Three continues to work to completely recover the B adhesive solution in the dip-coating device of the production line back to the mixing kettle. When the dip-coating device of the production line detects that the adhesive solution recovery is completed, at this time, Pump Five works, Valve Four is opened, and the adhesive solution A in the glue storage kettle is transported to the dip-coating device of the production line. After the transportation is completed, Pump Five stops, Valve Four is closed, and the production line proceeds with the production of Product A. At this time, the mixing kettle re-prepares the adhesive solution A. When the mixing kettle prepares the adhesive solution A, at this time, Pump Three and Pump Four work, Valve Three is opened, and the adhesive solution starts to circulate.

[0104] The production process of Product A is the same as the control principle of Product B.

[0105] Step Seven: Production Completed, Adhesive Solution Discharged

[0106] After the production of Product A is completed, Pump Four is closed, Valve Three is closed, and Pump Three continues to work to completely recover the B adhesive solution in the dip-coating device of the production line back to the mixing kettle. When the dip-coating device of the production line detects that the adhesive solution recovery is completed, Pump Three is closed. At this time, Pump Four works, Valve Six is opened, and the adhesive solution is discharged into the waste liquid bucket.

[0107] Step Eight: Activate the Automatic Cleaning Function

[0108] Pump One works, Valve One is opened, and the solvent is input into the mixing kettle. When the liquid level sensor detects that the solvent reaches the preset height, Pump One stops working, and Valve One is closed. The stirring systems of both kettles work simultaneously. At this time, Pump Four works, Valve Five is opened, the solvent enters the glue storage kettle from the mixing kettle, Pump Five works, Valve Four is opened, the solvent enters the dip-coating device of the production line from the glue storage kettle, Pump Three is opened, and the solvent returns to the mixing kettle again. The solvent circulates and cleans in the entire system. When the cleaning time reaches the preset time, Valve Five is closed, and Valve Six is opened. The waste liquid is finally discharged into the waste liquid bucket. After the cleaning is completed, all pumps are closed, and the valves are closed.

[0109] Step Nine: Automatic Cleaning Function of Key Detection Devices

[0110] When Pump 1 operates, Valve 2 opens, and the solvent flushes the specific gravity sensor and the liquid level sensor. The waste liquid is directly discharged through Pump 4 and Valve 6. Thus, the entire operation is completed.
