What is cement packing machine?
Cement packing machine
is a special equipment necessary for the production of bagged cement. Automatic cement packing machine
is used to complete the automatic packing of cement, and can also be used to pack other powdery materials with good fluidity (such as fly ash, cement additives, etc.), so it is still widely used in small and medium-sized cement factories.
Working principle of cement packing machine
The cement material
from the silo enters into the hopper shell of the packaging machine. The manual insertion of bags at the same time to start the travel switch, the signal transmitted to the microcomputer. Start the solenoid valve, through the cylinder work. Open the discharge nozzle, by the high-speed impeller will cement materials through the discharge nozzle continuous filling and woven bags. When the weight of the bag reaches the set value, the sensor of the automatic cement packing machine
will send a signal to the microcomputer. Solenoid valve through the microcomputer control to start the cylinder, close the discharge nozzle customized filling. At the same time the solenoid valve through the sensor's signal for suction, the bag presser role, so that the bag automatically tilt off the bag.
The whole filling process of cement bag packing machine
is electrical integrated control, in addition to manual insertion of bags, cement bag pressure, the opening and closing of the discharge nozzle; cement bag filling, weighing and measuring, automatic bag dropping and other functions can be completed automatically, thus reducing mechanical failure and ensuring the efficient operation of the packaging equipment.
Structure of cement packing machine
Rotary cement packing machine
The supporting equipment of rotary cement packing machine has vibrating screen, spiral gate. Feeder, chute, packaging machine host, packet conveyor, packet conveyor, packet conveyor, clean packet conveyor, load cell, material level controller, etc., and sometimes according to the different requirements of the cement plant as a supporting
Fixed cement packing machine
Fixed cement packing machine is mainly composed of machine body, feeding mechanism, control mechanism, microcomputer weighing mechanism and bag hanging mechanism.
|Frame||Frame adopts welded structure of section steel, high strength, large steel degree, compact and lightweight.
|Feeding mechanism||The feeding mechanism consists of 2.2KW planetary cycloid reducer, driving the small sprocket, through the chain, large sprocket to drive the feeder rotation to complete the feeding. The organization can be turned forward and reverse.
|Ash discharging mechanism||The ash discharging mechanism is driven by 4KW motor to rotate the spindle impeller, and the rotating impeller discharges the cement into the packing bag through the ash discharging pipe.
|Control mechanism||Insert the cement bag, pull the handle (i.e. open the gate) and start filling. When the cement is filled to the specified weight, the weighing mechanism sends out a signal, the electromagnet sucks, the control mechanism closes the gate, the filling stops, and the bag falls off automatically.
|Microcomputer weighing mechanism||Cement packing machine adopts microcomputer weighing, which is characterized by convenient adjustment and stable bag weight.
|Bagging mechanism||Cement bag packing machine has a unique and novel automatic bag dropping device. When the cement is loaded to the calibrated weight, the gate will be closed, the automatic bag dropping device will work, and the cement bag will fall off and tilt outward, leaving the packing machine.
Impeller fixed cement packing machine
Impeller fixed cement packing machine mainly consists of machine body, feeding mechanism, ash discharge mechanism, control mechanism, microcomputer weighing mechanism and bag hanging mechanism. The machine body adopts steel welding structure, high strength, large steel, compact and lightweight.
|Feeding mechanism||The feeding mechanism is driven by the cycloid reducer, driving the small sprocket, through the chain, the large sprocket drives the feeder to rotate to complete the feeding. (Single nozzle packaging machine without feeder)
|Ash discharging mechanism||The ash discharge mechanism is driven by the motor to rotate the spindle impeller, and the cement will be discharged by the rotating impeller and loaded into the packing bag through the ash discharge pipe.
|Control mechanism||The control mechanism is activated by the travel switch, and the cylinder is controlled by microcomputer and solenoid valve to open the discharge nozzle, realizing the control of electrical appliances in one automation.
|Microcomputer weighing mechanism||The ventomatic cement packing machine adopts microcomputer weighing, which is characterized by convenient adjustment and stable bag weight.
|Bag dropping mechanism||The machine has a unique and novel automatic bag dropping device. When the cement is loaded to the calibrated weight, the discharging nozzle closes and stops filling at the same time, the electromagnet suctions through the signal of the inductor, and the bag presser works, the automatic bag dropping device works, and the cement bag is dislodged and tilted outward, leaving the packaging machine.
Working process of cement packing machine
Steps for starting operation
b. Start the belt conveyor
c. Start packaging machine
d. Start the feeder
e. Insert bag
h. Dropping the bag
Steps for stopping the machine
a. Turn off the feeder
b. Empty the packer of cement
c. Turn off the main power
Feature of cement packing machine
a. Wide range of adaptability, where the fluidity of the powder, granular substances can be used to pack this packaging machine.
b. Basic automation, filling, measuring, bag dropping and other actions are automatically and continuously completed.
c. The working environment is clean and environmentally friendly, no bag insertion, no filling, no dropping of bags if the bag weight is less than the calibrated value, and the bag accidentally falls off, the gate immediately closes and stops filling. The gate immediately closes and stops filling.
d. Simple maintenance, less wearing parts, no hydraulic and pneumatic components.
e. Eight to twelve nozzles rotary cement packing machine is equipped with cement clearing machine, cement catching machine, cement vibrating screen and feeder.
Use of cement packing machine
a. Make sure the safety protection device of cement filling machine is intact.
b. Confirm that all parts of the cement packaging machine are well lubricated and the bolts are not loose.
c. Make sure the filling motor belt of cement bag filling machine is not broken.
d. Verify that there are no other people or objects around the packer.
e. Check whether the bag dropping position meets the bag dropping requirements.
f. Insert the bag, body and the machine to maintain an appropriate distance to prevent injury, is strictly prohibited to touch the operating parts of the equipment.
g. Don't squeeze or kick the cement bag with your hand when filling, so as not to affect the measuring accuracy.
h. It is strictly prohibited for non-job personnel to operate the cement bag sealing machine at this post, and prohibit the operator from crossing the safety cordon.
i. If the package is found to be broken or clogged, it should be stopped immediately and put up the warning sign of "Prohibition of closure" to deal with it.
j. Check whether the rotary device and solenoid valve are flexible and effective, and whether the material outlet is smooth.
Precaution of cement packing machine
a. Turn on the power of the packaging machine before starting the machine, and then turn on the feeding equipment or open the gate, turn off the feeding equipment and gate before shutting down the machine, and then turn off the power of the packaging machine, in order to prevent the packaging machine out of the ash system is blocked.
b. Frequently check the weighing device, pay special attention to the use and maintenance of the traction solenoid. If you find the body shaking too much, you should find out the reason and deal with it in time, and check the tightness of the machine body ground bolts.
c. Operators need to often clean the bagging mechanism, there should be no sassafras, leaning, support, card and other phenomena.
d. In the process of bagging, do not use your hands to press the cement bag, so as not to affect the weighing accuracy.
e. Remove the spring plate on the primary bagging frame must be re-dynamic weighing calibration.
f. The gate seal packing should not be pressed too tightly to avoid affecting the flexibility of the gate switch. It is strictly prohibited to add lubricating oil. If you find that the gate has a tight phenomenon, adjust or replace the new filler in time.
g. The main shaft of the power head of the ash discharge mechanism is lubricated with grease, and the grease is added at least twice a week.
