Frequently Asked Questions - 900MWS Vevor

What is the power supply voltage of the Vevor 900MWS?

The machine operates on 230 V / 50 Hz (or 110 V / 60 Hz depending on version). Check the nameplate before connecting.

How to adjust the sealing temperature?

Use the temperature control knob on the control box. For polyethylene, set between 150-160 °C; for polypropylene 170-180 °C; for polyolefin compounds 180-190 °C. Adjust according to film thickness.

What to do if the sealing belt shifts?

Check the parallelism of the driving wheel shafts. Use the adjustment screws on the driving wheel support to realign the belt.

Why doesn't the conveyor belt move in sync with the sealing belt?

This is often due to insufficient conveyor belt tension. Tighten the drive roller shaft chain and the conveyor belt according to instructions.

How to convert the machine to vertical mode?

Loosen the conveyor station adjustment knob, remove the station, mount it on the vertical tripod, install the long shaft and umbrella seat, then fix the height knob. Follow the 'How to change horizontal type to vertical type' section in the manual.

What types of plastic films can be sealed?

The machine can seal polyethylene (PE), polypropylene (PP), aluminum films, multi-layer composites, etc. PVC bags or paper alone are not compatible.

How to maintain the sealing braid?

Clean it regularly to remove film residues. If worn or burnt, replace it by pushing the driving wheel, removing the old braid and installing the new one. Refer to the 'How to maintain and repair' section.

What if the embossing is not clear?

Check the wear of the embossing wheel and the spring pressure. Replace the wheel if necessary, or adjust the spring tension.

How to correctly use the machine to avoid jams?

Ensure that the gap between the heating and cooling elements is equivalent to the thickness of a single bag. Do not push or pull the bag during sealing; let it advance automatically.

Where to find spare parts and technical support?

Spare parts (braids, blocks, wheels) are available from the manufacturer. For technical support, contact support via www.vevor.com/support.

material for children.

Dropping, falling, pressure, or tensile forces could destroy or at least limit the function of the product.

Never position the device in the vicinity of combustible or easily inflammable materials.

Always make sure that the rotary table on which the object is placed is located at the center of the housing!

This machine is suitable for plastic film sealing and bag making, and can be used in industries such as food, medicine, chemicals, daily necessities, and seeds.

Because the machine adopts electronic constant temperature control and an infinitely variable speed transmission mechanism, it can seal plastic bags made of various different materials. Due to its small size, wide application, and unlimited sealing length, it can be used with packaging lines. It will be the best sealing equipment for factories and bulk product packaging.

Due to the simple electrical control of the machine and the reasonable and refined mechanical transmission, its structural performance is very stable, the failure rate is very low, and the service life is longer. It can work continuously for a long time to meet the needs of mass production. The sealing package produced by the machine gives the product a beautiful appearance, and is clean, dustproof, moisture-proof, damage-proof, and easy to handle and store. It greatly reduces product loss and offers packaging cost advantages.

If you have reason to assume that safe operation is no longer possible, disconnect the device immediately and secure it against inadvertent operation.

It can be assumed that safe operation is no longer possible if:

• the device shows visible signs of damage,
• the device no longer functions,
• after a longer period of storage under unfavourable conditions,
• following heavy stress during transportation.

OPERATING INSTRUCTIONS

Names of the control box

Preparation prior to starting the machine:

1. The machine is equipped with a shell-grounded triplex socket, which should be well grounded to ensure safe production.
2. The electro-thermal component should be preheated at a low temperature for a few minutes before normal operation, as it may be damp from use or after long periods of inactivity.

1. Adjust the height and the front-and-back position of the conveyor station to fit the necessary level of the sealing bag's exterior.
2. Adjust the position of the guide plate for sealing width regulation according to its requirements.
3. Adjust the spaces between the upper and lower heaters and the upper and lower coolers (i.e., the spaces between the sealing braids) according to the necessary thickness of the sealing material.

Operation:

1. Turn on the power; the indicator lights will come on, and all wheels will begin their synchronized running.
2. Adjust the knob of the pattern roller to have it (or the inker wheel) rotate with regulated, suitable pressure.
3. Turn on the heating switch; the green lamp of the electronic temperature control meter lights up. Adjust the meter to the necessary temperature according to the nature and thickness of the packing bag's material. In general, the following values can be used for the above adjustment at a room temperature of 20°C:

a) Polyethylene: 150–160°C b) Polypropylene: 170–180°C c) Polyolefin compound: 180–190°C

The flexibility of temperature adjustment can be increased along with adjustable speed.

The red lamp lights up after heating for a while, indicating that the required temperature has been reached. Then, a trial run is adjusted based on the sealing result to achieve an ideal sealing quality, and after that, continuous sealing can be processed.

1. Determine if the blower needs to be turned on for cooling according to the thickness of the sealing material. (It should be turned on for common polyethylene and other single-layer plastic films.)
2. The sealing part of the bag should be aligned and laid flat. Push the regulation place for the sealing sides in, and at the moment when it is gripped by the sealing braids and moves forward by itself, neither pushing nor stopping, nor putting in or pulling out with force, can be done; otherwise, uneven sealing or faults may result.

WAY TO CHANGE THE HORIZONTAL TYPE INTO THE VERTICAL ONE

(1) Install two tripods and two horizontal beams with M4 screws. The concave of the tripod faces inward, while that of the beam faces downward.

(2) Loosen the regulation knob of the conveyor station's in-out and pull the station out, then take out the knob and the square fixing screws to the station.

(3) Mount the station onto the vertical tripod and tighten the fixing knob.

(4) Take out the horizontal short axis and install the horizontal long axis and the umbrella gear seat.

(5) Put the long axis into the axial hole on the machine and the horizontal support into the vertical support, install and tighten the height regulation knob.

(6) Vertically place the sealing machine for vertical sealing. 8. WAY TO MAINTAIN AND REPAIR

(1) Way to maintain

a) Push the driven wheel toward B and take out the sealing braid. b) Change with a new braid and install the upper and lower lead belts. c) Place the driven wheel, the heater, and the cooler in their original positions.

d) Turn on the power to make the pulley rotate and the braid drive move, then start a trial. The edge-deviation, if any, on the sealing braid should be adjusted through the screw on the driven wheel.

e) Install the safety guard, then continuous operation can be done at heating. g) In order to prolong the duration of the sealing braid, before stopping the machine, return the rotating disk of temperature adjustment to zero place and turn on the blower. At that moment, the temperature point begins to slowly fall down but the sealing braid is still running. It cannot be done to turn off the blower, the master power switch, etc., until the temperature becomes under 100°C in minutes. (2) Turbo case:

As an overall sealed turbo and worm unit, the turbo case has the features of low noise, large power, etc. It is oiled with 50g of 20# oil only once a month and cleaned and maintained only once a year, calculated per 8 hours a day when in use. Cares should be taken to keep the inside of the case clean when maintaining to avoid noise.

COMMON FAULTS AND SOLUTIONS

Problem	Reason	Solution

Adjust the pressing wheel or embossing w to proper pressure, so as to make the cle between two sealing belts be about thickness packing bag in one layer so that not only the strong sealing and clear printing, but no make the two ends of sealing part extend long.2. Adjust limiting screw after adjusting clearance。
Conveying belt is off-tracking	The driving roller shaft is parallel to driven roller sh	Adjust two adjusting screws for driven roller (rear shaft) on conveyor.
