Combination weigher Talking about the working
????With the continuous development of packaging companies, considering the comprehensive situation of cost and weighing speed, more domestic development-oriented enterprises that pursue high speed and high efficiency have successively purchased economical and practical domestic portfolios, and gradually eliminated the previous manual quantitative weighing packaging. Backward way. The domestic packaging industry has reached a new level in terms of improving and improving the production environment, increasing the degree of automation in production and management, reducing costs and hygienic packaging. This is an opportunity as well as a challenge.
????From the traditional standard combination scale, to the development of salad scales, potato scales, chopstick scales, noodle scales, waterproof scales specially designed for different materials; the development of a mini combination scale designed to reduce the size of the equipment; to the development of improved weighing The double chute combination scale designed for speed, the three-layer combination scale with memory hopper; and even developed into an integrated machine integrating the combination scale and the packaging machine.
????Combination scale The principle of the combination scale of the manufacturer:
????1. The material is sent to the storage hopper by the material conveyor. When the material is added to the preset horizontal position, the electronic eye on the side of the storage hopper detects and sends a signal to stop the conveyor feeding until the horizontal position of the material on the storage hopper drops At the preset horizontal position, the electronic eye sends out the feed signal again;
?
????2. The material is in the storage hopper, and the material from the main vibrating plate is evenly dropped into the line vibrating plate through the vibration of the main vibrating machine to feed each line vibrating plate;
?
????3. The vibration of the line vibrator causes the materials to be discharged from each line vibrating plate and enter the feed hopper for storage;
?
????4. When the weighing hopper completes the last weighing and emptying, the upper feed hopper is opened to allow the material to enter the weighing hopper for weighing. The output signal transmits the data to the main board of the control device through the lead, and the CPU on the main board reads and records The weight of each weighing hopper, and then through calculation, analysis and combination, select a combination weighing hopper that is close to the target weight;
????5. In the weighing hopper, the weight signal is generated by the sensor, and then transmitted to the main board of the control device through the lead. The CPU on the main board reads and records the weight of each weighing hopper, and then calculates, analyzes, and combines. The combined weighing hopper that is close to the target weight is selected. When receiving the request to discharge the signal sent by the packaging machine, the CPU sends a signal to start the weighing hopper motor driver to open the selected weighing hopper to unload the product into the lower chute and enter Packaging machine (if there is a collection hopper, the weighing hopper is assembled and directly discharged to the collection hopper. When there is a request for a discharge signal, the hopper motor is started to discharge the material to the packaging machine);
????6. When the weighing hopper (collecting hopper) is finished with materials, the computer combination will send a signal to the packaging machine that has been discharged, and the packaging machine will start to seal and cut the bag after receiving the signal, when the packaging mechanism is good After a bag, it sends a request to unload the signal to the computer combination called the computer combination called unloading, and so on.
