1. GQ-20K/50K packing scale (pneumatic and vibration)
The packing scale is the integration of mechanical and electrical products, using double metering control system independent of each other, the fusion of several of the latest technology, performance index occupies the domestic leading level of similar products, the automatic quantitative packing is suitable for sugar, salt, food, feed, chemical industry production line of granular materials.
2. Structure and principle
The machine is divided into two parts of mechanical and electric control. The electric control part is composed of a pressure sensor and an electric control box and other components; the mechanical part is composed of multilevel feeding mechanism, power metering hopper and a bag clamping mechanism, a frame and other parts. Electronic balance work, under the control of a controller, a discharging door closed first, automatic peeling cleared then the opening of the material feeding mechanism and feeding, constantly enters the measuring bucket, pressure sensor convert the weight of material into a corresponding electrical signal, sent to the controller. Controller in the panel window shows the weight of the material value, and sequentially outputs a control signal according to the settings of the parameters, make the feeding mechanism to feed in quickly, medium, or slow velocity, now we change to a single group separation plus vibration feeding material form, without shaking to complete accurate quantitative feeding, because the whole machine shaking badly when we use the three stage group separation. It will absolutely not damage the appearance of materials. Feeding mechanism are all closed after the end of the process, the metering bucket open the discharging door first when the quantity is enough, the material filling in turn through the bag clamping cylinder. After discharge, discharge door close, the folder bag institutions open drop packet. bag toggle switch control bag clamping mechanism Opening and clamping for artificial bagging operation; and only when the bag clamping mechanism is arranged in the clamping state, the controller will send irrigation discharge packet control signal. 
3. Characteristic
a. using the measurement system independently, without mutual interference, high packing speed;
b. measurement and control system adopts high precision sensor, controller and display multi feeding mechanism specially designed conversion rate of 500 times per second, control algorithm combined with science, high measuring precision, good stability;
c. the operation is simple, the operator only needs to bagging and touch bag clamping switch, and feeding, bag filling, bag unloading action by the scale automatically;
d. a manual control switch, manual control of feeding, feeding mechanism, which is convenient for cleaning the residual material.
e. and material contact parts all use stainless steel.
f. Technical characteristics
(1) packaging net weight: 10-50kg/ bag
(2) packing precision: 0.1%F.S ( 10g)
(3) packing speed: 250-400 bags / hour
(4) working mode: artificial bagging, automatic bag clamping touch stroke switch, have been weighing material automatic bag filling, automatic bulk.
(5) the scale body can be directly installed on the floor, but also can be installed in the steel structure platform
(6) with manual and automatic two kinds of operating mode, normal mode of operation for the automatic, manual for debugging, calibration and maintenance.
(7) quantitative value can be settled  through the instrument keyboard  in the quantitative range, In rated packing weight of 10 ~ 200% range arbitrarily set packing weight value.
(8) the weight of packaging and packing times can be automatically displayed, may at any time to display the current weight of packaging and packaging count.
(9) have a fault or mistake operation diagnosis, fault code hinting, measurement deviation alarm
(10) automatic return to zero, and each cycle is to detect zero, automatic correction.
(11) with 485 communication interface, can communicate with computer.

4. Lift conveyor
a. Belt conveying sewing machine comprises conveyor frame (including belt conveyor, motor), sewing machine column (including sewing machine, sewing machine, the operating control box)
b. Conveyor length: 2.2 meters, width: 0.40 meters.
c. Conveyor speed can be adjusted with the sewing speed matching. Conveyor adjustable height, sewing machine capable of lifting and bag height matching.
d. Field operation control box is equipped with control button, itinerary protection and air switch (control appliance adopting Schneider).
e. Sewing machine by GK35-2, using a single needle double material will not fall on the packaging bags with material management at.
