 Unloading part adjustment

1.Unloading time adjustment

1.Start the host, close the unloading clutch. Shut down the machine when the outer bag horizontal sealing roller is sealed, observe if the measuring cup is precisely aligned to the material leakage port of the unloading plate (see Figure 7-1).

2.When the measuring cup is not aligned to the material leakage port, lift the feeding unloading adjustment handle so that meshing gears are disengaged.

Warning: It is prohibited to disengage the unloading clutch at this time.

3.Clockwise rotate the feed tray so that the next one measuring cup just turn to the leak material port, and then put aside the feed unloading adjustment handle, lightly rotate the feed tray back and forth so that the gears are meshed with each other.

Warning: The amplitude can be not too large when lightly rotating the feed tray back and forth, while the feed connecting bar can not be moved, or else the feed line time line

2.Material weight adjustment (Figure 7-2)

1.Reduce weight: rotate the weight adjusting hand wheel in the clockwise direction;

2.Increase weight: rotate the weight adjusting hand wheel in the counter-clockwise direction;

3.If the required packaging weight exceeds the scope of measuring scale, replace the measuring cup.

Figure 7-1

1. Counterclockwise     2. Clockwise

3.Drum unloading port adjustment (Figure 7-3)

According to material liquidity difference, adjust the height of the drum unloading port, if the material flow is poor, the unloading port height should be adjusted a relatively high; on the contrary, if the material flow is better, the unloading port height should be adjusted a relatively low. It is better that the materials in the drums are enough in the feed tray and not piled up.

Figure 7-3

4.Scraping plate adjustment (Figure 7-4)

Release the fixed nut of the scraping plate, so that 0.2 to 0.5mm gap between the scraping plate and feed tray surface is maintained, and then lock the nut. The actual situation should be based on that the scraping plate can clean up the feed tray surface.

Warning: It is prohibited for the scraping plate to contact with the feed tray surface,

otherwise it will damage the feed tray.

Figure 7-4

Warning: the cover disallows to run into the flange when the cover open full.

※Adjusting the cutting 

Adjusting the position of cutting

f. push and move the cutting gear left take it break away the transfer gear did not release;

g. turn the cutting gear, deasil to ahead and anticlockwise to lag;

h. release the cutting gear take to mesh with the transfer gear.

8. when cutting broken the sachet difficult

when difficult to cut the sachet broken. Change or grind the cutting knife. And adjust the clearance of the cutting knife by the push screw and tauten screw screw on the cutting bracket. The best clearance of 0.02mm between knifes.

Warning: 1. The clutch must be closed when adjusting;

2. Stop the machine when adjusting.

Adjusting for the tea bag length

When the machine was send from factory. We setting the machine for the tea bag length according the buyer asking. But the tea bag can be changed more or less 5mm by the length transfer gear.

For the factory setting. We set the medi-transfer gear mesh the gear 1. if you want the tea bag length less 5mm, please move the bracket to take the medi-transfer gear mesh gear 2. if mesh in gear 3 will take the tea bag length more 5mm.

Adjusting for The Prejudicial Sprocket wheel

Purpose

1.keep the circumference speed of the vertical sealer and horizontal sealer in the same speed;

2.when change the length of the sachet you must adjust the prejudicial seat of the prejudicial sprocket wheel, in addition to change the transmission gear.

Adjusting:

1. turn the horizontal sealing roller as the picture as;

2. release the nut on the screw;

3. turn the adjusting knob to move the cross nick to the scale you need;

4. locknut to finish the adjusting.
