11. Debug rules

The operators should debug the machine in accordance with these rules. The standard procedure for adjusting synchronization is as follows:

1. Adjust film feeding system(including blade adjustment);

2. Adjust film feed to synchronize it with feed article propulsor;

3. Adjust turret to synchronize it with feed article propulsor;

4. Adjust turret to synchronize it with discharge article propulseor;

5. Adjust long interface seal A and long interface folding pawl;

6. Adjust side edge-folding;

7. Adjust side seal.?

Brief description:

(1) Adjust the film feed system

1) Open the clutch on the blade arm.

2) Adjust the unsealing pull line and film supply(see Figure 4),

Turn the handle on the blade arm to observe the pilling out. If the resistance

is too large, the feed length will be less than the specified value, and the unsealing pull line will wrinkle; if the resistance is too small, the film will???????? bounce and wrinkle. Under this condition, it is necessary to adjust the???? degree of tightness of the brake of film reel axle.

3)? Adjust the blades(see Figure 5)

a)?????? First adjust the turning blade. Loosen the fastening screw so that the edge of blade just passes through the tangent line of the feed roller and rubber roller, then tighten.

b)????? Adjust the fixed blade. Loosen the fixed blade, tighten the screw gently. Turn the adjusting screw at outside of the blade using screwdriver. Move the fixed blade forwards gently until the fixed blade slightly touch the turning blade, Then tighten the screw. Inspect the cutting effect. If the cutting is not very effective, adjust again. If both sides of the film are cut off and the middle is not cut off, or the opposite of this, the edge of blade had not been well polished possibly or has damage, thus dressing is needed.

c)?????? Adjust the small blade. First determine the location of the unsealing pull line. Loosen the fastening screws of the small blade and the bearing wheel. Move the small blade to the cutting location, and tighten the screw. Adjust the adjusting screw of the bearing seat of the pressure bearing wheel axle of the small blade by using screwdriver, so that the pressure bearing wheel moves forwards gently, until it touches the edge of the small blade evenly. It would be best if the pressure bearing wheel turns simultaneously when the small blade is turning. Then place the film in, and inspect the cutting effect.

d)????? Adjust the relative position of the small blade, blade and feed roller.

After the blade and small blade are adjusted respectively, inspect the film cut down. If tearing appears at the corner of the small blade mark, it is necessary to adjust the circular velocity of the small blade when cutting This is because the instantaneous circular velocity of the small blade when cutting should be synchronous with the film feed speed. Otherwise, the film will be sure to be torn, and the pair of elliptic gears on the blade seat needs to be adjusted. When adjusting, loosen the fastening screw of the driving elliptic gear(see Figure 6) and turn to the left and right, until the requirements are met.(see Figure 7).

4)? Close the clutch.

(2)? Adjust the synchronization between film feed and feed article propulsor.(see Figure 8)

Under normal condition, the standard of synchronization of the film?? feed with the feed article propulsor is as follows: The film is carried down by the feed drum, and the articles to be packed is propulsed forwards by the feed articles propulsor. When the top end of the articles to be packed touches the film and carries the film to move further forwards about 15-20mm, the film is cut off(otherwise determined for special articles). Then packing is carried out.

When adjusting, loosen the fastening nut used for tightening the end surface clutch so that both sheets of clutch are separated mutually. Turn the outer end surface clutch sheet to a certain angle, then tighten the fastening nut, and observe film feeding and propulsor synchronization until synchronization of film feed with feed article propulsor.

(3)? Adjust the synchronization between turret and feed article propulsor.

Observe the synchronization of the pack articles pushes out by the feed article propulsor with the turret intermittent turning. If not, adjust as follows:

1. Loosen the fastening screw at the connection of pinion and groove wheel at the back of the machine body.

2. Turn the pinion so that there exists the relative moving between the pinion and groove wheel.

3. Tighten the screw.

4. Observe the adjustment. If not synchronous, repeat the above steps.

(4)? Adjust the synchronization between turret and discharge article propulsor.

Observe the smooth push-out of the articles when the turret is working. If not, adjust as follows:

1. Open the rear housing opening, loosen the fastening screw on the driving axle of the discharge article propulsor which tightens the chain leaf.

2. Turn the flange so that there exists the relative turning between the flange and the chain leaf.

3. Tighten the screw.

4. Observe the adjustment. If not synchronous, repeat the above steps.

(5)?? Adjust the long interface seal A and long interface folding pawl.

Start the machine to observe the long interface fold and initial seal. If

they cannot be completed, it is necessary to adjust the long interface fold cam and the long interface initial seal cam at the back of the machine body(the inner is the fold cam). When adjusting, loosen the fastening screws of the cams, and turn them.

(6)?? Adjust the long interface seal B.

The procedure is the same as for the long interface seal A.

(7)? Adjust side edge-folding.?
