Technical characteristics of ton bag packaging machine

by admin

1. Ton bag packaging machine is customized and designed according to the respective characteristics of powder materials and the different requirements of manufacturers. The equipment is technologically advanced, durable and has few vulnerable parts
2. The feeding and packaging of ton bag packaging machine are stepless speed regulation, with stable equipment performance, high packaging precision and fast speed
3. Programmable electric control system, the control process is highly reliable
4. Advanced dust-proof and dedusting design to reduce dust pollution in the working environment
5. The weighing system is an electronic scale platform scale, which adopts full panel digital adjustment and parameter setting. It has the functions of weight cumulative display, automatic peeling, automatic zero calibration, automatic drop correction and so on. It has high sensitivity and strong anti-interference ability
6. The instrument is equipped with communication interface, which is convenient for online networking, and can carry out real-time monitoring and network management of the packaging machine
weighing and debugging method of ton bag packaging machine
after checking that the sensor wiring is correct, turn on the power supply of the control cabinet and preheat for 15 minutes before debugging. In this paper, the maximum weighing capacity is 100kg and the division value is 0? 郾 2kg, quantitative value 90kg and accuracy grade meet the technical requirements of X (0 × 郾 2), as an example, it is introduced as follows:
(1) eccentric load adjustment
place 10kg weight on two load-bearing points of the weighing bucket respectively. When the weighing display shows “positive difference”, the sensor output shall be adjusted in the downward direction; When the weighing display shows “negative difference”, the sensor output shall be adjusted in the increasing direction. For example, when the output of L /C-1 sensor decreases, rotate a set of trimming resistors related to L /C-1 (the original value is 10 ohms) to the left with the same amount of rotation. Rotate to the right (clockwise) to reduce the resistance value and increase the display value (recorded as “plus”); Turning to the left (counterclockwise) increases the resistance value and decreases the displayed value (recorded as “minus”). Note: when rotating the trimming resistor, if the rotation amount of each group of two is inconsistent, it will make the adjustment difficult. Therefore, the rotation amount of each group of trimming resistor of the sensor should be consistent as far as possible. If the absolute error of each bearing point is no more than 10g, it is qualified
(2) weighing adjustment
carry out weighing adjustment according to the calibration steps in the weighing display controller manual. During verification, the weights shall be increased in the order of 0kg, 40kg, 70kg, 90kg and 100kg from the zero point to the maximum point, and the error shall not be greater than 10g, 20g, 35g, 45g and 50g respectively; Reduce the weight in the order of 100kg, 90kg, 70kg, 40kg and 0kg respectively from the maximum value to the zero point, and the error shall not be greater than the respective allowable error; The repeatability verification shall be carried out at two quantitative points of 40kg and 100kg, and each weighing point shall be carried out three times, and each time the error shall not be greater than their respective tolerance
(3) parameter setting
there are many parameters to be set for the quantitative packaging scale. The following is an example of common key parameters: a. the quantitative value of the weighing display controller can be set as the quantitative target value, such as 90kg. B. slow and fast acceleration. When weight & gt; (set value) – (advance of fast acceleration), stop fast acceleration and switch to slow acceleration; When weight & gt; (set value) – (advance of slow charging), stop charging
