The automatic filling machine can complete can feeding, metering, filling, waste discharge, and other tasks, and can be matched with other equipment to form a complete canning assembly line. It is suitable for liquid materials with extremely poor fluidity, such as electrolytes, lubricants, paints, resins, inks, solvents, additives, thinner, etc. At present, the production speed of the fully automatic methanol filling machine on the market is about 30 cans/min.
Process description of ethanol liquid filling machine:
The core of the process of the automatic adhesive filling machine lies in two fillings: pre-filling and supplementary filling. The peeled empty can is sent by the hydrochloric acid filling system to the bottom of the pre-filling for pre-filling. The pre-filling amount is set in the PLC in advance, and the filling screw is driven by the servo motor according to the pulse command of the PLC to fill. After the pre-filling is completed, the alcohol solution metering and filling machine will send the tank to the pre-filling and weighing station, which will be measured by the alloy steel weighing module (generally, about 1%-5% of the target weight will be reserved during pre-filling. Fill in the space), feedback the actual value of the weighing to the PLC, and calculate the amount to be filled by the PLC (complementary filling amount = target weight-actual value of pre-filling weighing), and the ammonia solution weighing and filling machine will The tank is sent to the refilling position to start refilling. After the replenishment is completed, the active agent quantitative filling machine is sent to the replenishment weighing module for testing. If the weight is qualified, the filling is completed and out of the tank; if there is a large gap from the target value, it is then sent to the replenishment by the emulsifier quantitative filling machine Fill the tank for the second time until the weight is qualified.
Suspending agent liquid automatic filling machine technological process:
The paint production automatic filling machine production line is a multi-material, high-precision, automatic filling line, including weighing, mixing, conveying, storage, and other links of automatic production automatic filling scales, the entire wetting agent automatic filling machine The key equipment material machine, control automatic filling scale (including hardware and software), etc., the various raw materials of the process are manually input and transported to the batching tank, and after the batching tank is automatically weighed by the explosion-proof electronic scale, it is discharged into the mixed material from the collection pipeline After mixing in the mixer for 3 minutes, it enters the designated intermediate batching tank from the conveying equipment. The paint weighing liquid filling machine has a weighing instrument that needs communication, and a computer needs to be used for online monitoring and management. The weighing speed, weighing accuracy, and adhesive weighing liquid filling machine have high compatibility and scalability. Requirements. Therefore, when designing and implementing the methanol explosion-proof liquid filling machine, it is necessary to comprehensively consider the adoption of communication methods and communication protocols, hardware architecture, control strategies, and software implementation.
Process structure of glycerin automatic liquid filling machine:
The metering liquid filling machine can realize 5 modes of action: manual, return to the original position, single step, single cycle, and continuous. In the manual mode, the corresponding actions are realized through the jog of each button. In situ action mode, press the “return to insitu” button, the liquid filling machine will automatically return to insitu. In the single-step action mode, each time the start button is pressed, the aromatic water agent weighing and filling machine is executed before one step. When the single-cycle action mode is selected, each time the start button is pressed, the colorant explosion-proof metering filling machine only runs for one cycle and then stops. In the continuous action mode, the aroma quantitative liquid filling machine hand is in the original position, press the start button, the latent solvent weighs the filling machine hand until the stop button is pressed. During the final movement of the liquid filling machine to the original position to stop transporting the workpiece, the solubilizing liquid weighing and filling machine must rise to the highest position to avoid contact with other workpieces when the solubilizing automatic weighing and filling machine moves at a lower position.
Dimethyl sulfoxide quantitative weighing filling machine technological difficulties:
Accuracy and speed are always a pair of contradictory points, so the process difficulty of polyethylene glycol automatic filling machine is to find the balance point between weighing speed and accuracy. After the filling is completed, the can is brought to the weighing pan by the ethyl acetate explosion-proof weighing filling machine for weighing. When it is brought to the weighing pan, a certain amount of jitter will occur, which will affect the accuracy of the weighing data. To improve the accuracy, a certain delay time must be set to make the weighing module weigh in a relatively stable environment, and too long a delay time will affect the speed of the entire system. OMRON’s CP1H-XA PLC has built-in 4 inputs and 2 outputs analog signals, with an accuracy of 1/12000 and a response speed of only 8ms. With high-quality heavy oil explosion-proof weighing modules, the system speed can reach 50 cans/min while ensuring accuracy When the range is 5Kg, it can reach within ±4g.
