各種閥全部采用通用閥，具有聯接，維護方便之優點，各閥由集成塊加以聯接，從而壓力損失小，漏油現象減少。各閥的作用和調節說明如下：

3.7.1 電液換向閥：本機共有2只，分別控制壓棉油缸和擋板油缸的進退換向，換向時回路上要有>3Mpa的背壓力。

3.7.2 溢流閥： 本機裝有大小各1只普通溢流閥，調整壓力分別為16Mpa和7Mpa，主要起到主油路及擋板油缸的安全，調節手柄順時針為増壓，逆時針為減壓。

3.7.3 壓力繼電器：本機裝1只壓力繼電器，調至13Mpa,用控制壓棉油缸棉包成形。

3.7.4 背壓閥：背壓閥主要起到使回油路上產生一定背壓力，便于各電液換向閥平穩換向。背壓閥的調節壓力為>3Mpa.

3.8 擋板上下，壓棉油缸進退均有行程開關控制。

3.9 各順序控制均有電器控制柜集中控制，操作方便。

3.1 The size of the baling chamber is 1000×650×855(mm),with two slots at both side walls, in the purpose for baling belts to pass through. There is knife mounted at the top inside of the chamber.

3.2 Cotton Dropping Box

3.3 Size of the Cotton Dropping Box：686×686×750(mm), which has Viewing Window, for operators to see the amount of cotton inside the box, to decide if it’s the right time to bale or not, there is photoelectric device mounted outside the window to control the baling act.

3.4 Cotton feeding: After being conducted by drum filter, the dropping cotton from blowing system and cards is fed by conveyer into the Cotton Dropping Box, through condenser or fiber presser. The noils and impurities from Cotton Waste Processing System are fed to each baling trunk respectively, and can also be fed manually. Conveying pipe system should be prepared by user.

3.5 Cotton Press Cart is welded by steel plates, angle steel, channel steel and other parts together, with 4 sets of roller mechanisms. When Cotton Press Cart works, rollers always roll on the guide ways, with low resistance or friction, the lower two rollers at both sides can be adjusted .The cart has lower-knife, the gap distance between the upper and lower knives can be no larger than 2mm.

3.6 Frame is welded by high-quality steel plates, with sleek outer lines, also with enough strength and rigidity, vibration and noise is low during work. Cotton Block Plate is placed at both ends inside the frame.

3.7 Oil Pump:

The oil pump is Vane Pump, work pressure 21MPa, and rated flow 27L/min.

3.8 Oil Cylinder

3.9 Valves:

Every valve is universal, so the connection and maintenance is easy. Each valve is connected by integration blocks, so oil pressure loss is low, oil leakage significantly reduced. The function and adjustment of each valve is listed below:

3.9.1 Solenoid Valve

In total there are two, control Cotton Press Oil Cylinder and Block Plate Oil Cylinder respectively. This kind of valve can work smoothly, with high flow, which also has a back pressure larger than 3 MPa at the back loop; the back pressure can be adjusted by back pressure valve.

3.9.2 Overflow Valve

This machine has one big and one small Overflow Valve, pressure adjusted to be 16Mpa and 7Mpa, main purpose is to make sure the safety of the main oil loop and Block Plate Oil Cylinder. The adjustment handle can be turned clockwise to increase the pressure, while counter-clockwise to decrease the pressure.

3.9.3 Pressure Relay

In total only one，adjusted to 13Mpa to control and maintain the pressure of the Cotton Press Oil Cylinder for a while, which is necessary for the baling.

3.9.4 Back Pressure Valve

Main purpose is to generate one certain pressure in the oil back-loop, thus the working of each valve can be smooth. The pressure should be adjusted to be>3Mpa.

3.10 The up and down of Block Plate, and the in and out of Cotton Press Oil Cylinder are both controlled by travel switch.

3.11 Every sequence of different activities is controlled by electric components inside the Electric Cupboard, simple and easy to operate, quick and safe.

4 工作原理　Work Principles

　　棉花經處理機處理后，落入棉箱，當棉層達到下棉箱光電管位置時，打包機壓棉油缸開始自動打包，成形后進行人工捆綁處理。

Cotton drops to the trunk after being processed, when the cotton level meets the height of the photoelectric detector, the Cotton Press Oil Cylinder of baling machine begins to bale the package automatically, then bundle the package. If the cotton level meets the position of the photoelectric detector inside the hopper box, the feeding of cotton stops.

5 操作使用與故障排除 Operation Instruction and Trouble Shooting

5.1 首先打開電源SA，再按下油泵啟動按鈕3ST，油泵開始供油，并將“手、自動”按鈕撥至自動位置。

5.2 當由纖維落下的棉層達到下棉箱光電管位置時，光電管動作，壓棉油缸工作。由壓棉小車將纖維推進打包室，達到一定位置，行程開關發出電信號，使壓棉油缸工退，至最后停止。

5.3 待光電管再次動作，壓棉油缸工進，這樣反復多次，當棉包壓成形后，成形壓力繼電器SP動作，壓棉小車自動停止，即可進行捆綁，捆綁結束，手按“推包”按鈕，即可自動將包推出打包室。

5.4 推出棉包后，在小車和擋板上掛好包布，再按“復位”按鈕，小車便自動后退至終點，擋板下降，在手動位置時，只有當小車退至終點，光電開關才能動作擋板只能下工作。

5.5 為使操作維修安全方便，電氣控制系統既能自動，又能手動，手動時各按鈕是點動。

5.6 在液壓油溫度50℃時，油液的運動粘度應在25~32厘沲之間，推薦使用N46號抗磨液壓油，在環境溫度較底時，應選用粘度較底的液壓油。油液應清潔，無有害物質。應定期檢查液壓油性能，更換油液并保持油面高度。

5.1 First, open the power SA, then push the oil pump button 3ST, the pump will start to work, also please turn the “ Manual/Auto” button to the position “Auto”.

5.2 When the height of the cotton falls from the Fiber Separator accumulates to a level where the photoelectric sensor inside the lower trunk can detect, the Cotton Press Oil Cylinder will work. The Cotton Press Cart then push fibers into the baling chamber, when the pressed fibers meet the position to let the travel switcher detect, which will give a signal to retreat the Cotton Press Oil Cylinder.

5.3 When the photoelectric sensor works again, the Cotton Press Oil Cylinder also works again, this circular can work again and again until the bale package finished, and then the cart stops. Afterward the bale can be bundled, and then push the “Push” button, the bale package can be pushed out of the chamber.

5.4 When the bale package is pushed out, the package cloth should be put onto the cart and block plate, then push the “Reposition” button, the cart can be retreated to the end point, and block plate goes down. When in the manual type, the block plate can work up and down only when cart retreats to the end point.

5.5 For better operation and maintenance, electric control system can be automatic and also manual, which is step by step manual control.

5.6 When the oil temperature is 50℃,kinematic viscosity of the oil is between 25~32 centistokes, N46# anti-wear oil is recommended. When the environment temperature is low, lower viscosity oil should be used. Oil should be clean, non-toxic, and without harmful substances. Oil performance should be periodically checked and changed, and the oil height should be maintained.
