Now the emulsifying machine in the production process, it needs to pay attention to many problems, so as to make the emulsifying machine production sequence, the following is a look at the emulsifying machine production common sense.

If the steam pressure of each pot of the vacuum emulsifying machine is too high when heating and there is air leakage, close the air inlet valve of each pot or the air outlet valve of the steam generator. Before the production of the vacuum emulsifying machine, try whether the runner in each pot is loose or does not move. If there is any fault, repair it in time. The vacuum should be removed first, and the lid can only be raised (hydraulic rise) after the pressure gauge drops to 0. When it rises to a certain height, it will jump automatically. When the lid of the vacuum emulsifier is lifted, pay attention to safe operation to prevent pressing hands, mechanical tools and other objects.

 

Each pot should not be idling for homogenization, and the idling test machine should not exceed 1 minute. Turn it by hand before opening. Homogenization can only be opened when stirring is opened.

The homogeneous relay shall set the delay time before turning on the switch. If the switch is turned on first, the problem of not automatically jumping when the predetermined time is reached will occur.

 

The vacuum emulsifying machine should be cleaned frequently. First, clean it twice with tap water, wipe it with a clean cloth, and wipe the materials on each pot and stirring paddle clean. Rinse twice with pure water and rinse everything.

 

Equipment inspection before start-up of 1. plastic granulator

1. Organize the actual operation staff and maintenance personnel to study the operation manual carefully, so that the relevant staff can master the working principle of the machine and equipment. Operating procedures, safety precautions, to facilitate the effective and appropriate actual operation of the machine and equipment.

2. The plastic granulator has been tested in all aspects before leaving the factory. In order to prevent problems in the handling process of the granulator equipment, the following work is still needed:

(1) Step by step to check whether the route of household appliances meets the requirements and whether they fall off.

(2) Use an ohmmeter to measure the motor and the electric heating part, and the grounding resistance should not be lower than 0.5 Ω.

(3) Fill the gear motor with grease to the center line of the oil window, and use high-quality grease. The oil tank of the hydraulic station is filled to the center line of the oil window.

3. Turn on the main switch power supply, adjust the temperature control of each pivot to the "set" temperature, and start heating and pressing.

4. When the temperature rises to the specified temperature of the processing technology, the temperature is controlled for 5 to 10 minutes.

5. Check and tighten the screws of the whole unit again.

6. Turn the belt reel by hand (screw rotation shall not be less than 2~3 turns) to make sure everything is normal, and install the protective cover of the belt reel.

7. Starting auxiliary system: such as lubrication, cooling, etc.

8. Start the main motor and determine whether the rotation direction of the main motor is appropriate.

9. Slowly drop about 500ml and 30# engine oil from the blanking port, and the strengthened and upper models will idle for about 1 minute and the standard models will idle for about 3 minutes. Pay attention to the ammeter and voltmeter. The voltage should be between plus and minus 10V of the rated voltage, and the current should be stable and free of fluctuation.

10. Stop the machine after making sure everything is normal, and the empty machine test is completed.

11. The head (die head) of the plastic granulator can be equipped with or without a filter screen (usually assembled in the form of a filter screen without a filter screen when leaving the factory), and the filter screen with the required mesh can be prepared for startup.

12. All aspects of the plastic granulator shall be inspected and ready to start after confirmation.

13. The above program flow is generally completed before the plastic granulator leaves the factory and can still be referred to when it is started again. 

A grinder is a grinder that grinds the surface of a workpiece with a coated or embedded abrasive. It is mainly used for grinding high precision plane, inner and outer cylindrical surface, conical surface, spherical surface, thread surface and other types of surface. The main types of grinding machines are disc grinding machines, rotating shaft grinding machines and various special grinding machines.

The working principle of 2. single-sided grinding machine:

Put the ground and polished materials on the grinding disc, the grinding disc rotates against the clock, the correction wheel drives the workpiece to rotate, the workpiece is pressurized by gravity, and the workpiece and the grinding disc are rubbed relative to each other to achieve the purpose of grinding and polishing. The grinding disc dressing mechanism adopts the hydraulic suspension guide rail to reciprocate back and forth, and the diamond shaving knife finely repairs the grinding surface of the grinding disc to obtain the ideal plane effect.

The working principle of 3. double-sided grinding machine:

The upper and lower grinding discs rotate in opposite directions, and the workpiece makes a star-wandering motion of revolution and rotation in the carrier. The grinding resistance is small and does not damage the workpiece, and the production efficiency is high for uniform grinding on both sides. There is a grating thickness control system, and the thickness tolerance of the processed product can be controlled. The device of the double-sided grinding machine includes two grinding discs, a cruise ship, four motors, a sun wheel, a shave machine, etc. Compared with the two, the structure of the double-sided grinding machine is relatively complicated, but if the workpiece that needs double-sided grinding is ground with a double-sided machine, the efficiency of the single-sided machine is virtually twice as fast. The birth and development of this double-sided grinding machine has brought improvements to the production efficiency of many industries. There are more silicon wafers, sapphire substrates, epitaxial wafers and so on in the optical glass industry.

What is the operation method of the grinding machine?

The operator shall be familiar with the general structure and performance of the equipment and shall not use the equipment beyond its performance. The sum of the volume of parts and abrasive tools shall not exceed 90% of the volume of the hopper. After the power is turned on, the idle operation shall be carried out, and the operation shall be stable without abnormal noise. Otherwise, stop the machine for inspection. Before the workpiece is ground, the workpiece shall be deoiled and decontaminated. In the process of processing, the amount of grinding agent and water should be added according to the grinding condition of the workpiece. After the work is completed, cut off the power supply, clean the equipment, and do a good job of equipment maintenance. Safety operation procedures Before starting up, check the fastening screws and check whether the rotation of the motor shaft is flexible. During the operation of the equipment, if any abnormality is found, the equipment shall be shut down immediately. Every 6 months, the vibration motor or the bearing oil filling port of the rotating shaft should be filled with lithium-based grease. After work, the power should be cut off.
