WE-LS6 Screw Packing Machine

A screw-packing machine is a fully automatic device that counts or weighs various items such as screws, nuts, bolts, washers, furniture kits, hardware parts, fasteners, and small components, and then packs them into pouches or boxes based on your specific needs. This machine offers high precision and operates quickly, effectively reducing labor costs for your business.

Worldepack offers a fully automatic multifunction screw-packing machine that is designed to provide easy operation and high efficiency. This machine is capable of counting, weighing, and filling screws, bolts, nuts, and small hardware items with an impressive accuracy rate of 99%.

Application:

Manufacturing industry: Screw packing machines are extensively used in manufacturing units where large quantities of screws, bolts, nuts, washers, and other fasteners must be sorted, counted, and packaged efficiently.

Hardware stores: Retailers and suppliers of hardware components benefit from screw-packing machines as they enable quick and accurate packaging of different types of screws, bolts, and small parts.

Construction industry: Construction companies often require large quantities of screws and fasteners. Screw-packing machines simplify the process of sorting and packaging these items, ensuring they are readily available and organized on construction sites.

E-commerce fulfillment centers: With the rise of online shopping, e-commerce fulfillment centers deal with a high volume of small parts and hardware items. Screw-packing machines automate the packaging process, reducing the time and effort required to sort and pack screws and other fasteners for shipment.

Assembly lines: Screw packing machines can be integrated into assembly lines, where they automatically dispense the required number of screws or fasteners for each product being assembled.

Machine counting screw nut bolt nail and plastic parts into one bag

 

This machine with 3 hoppers suitable for counting small quantity screws in each bag.

This counting machine is suitable for larger quantity per bag and also ensure accuracy and speed. The customer’s screw length is 45mm, 200 pcs per bag then 5 bags per min, screw length 20mm, 400 pcs per min, about 8 bags per min. Our engineer set the PLC to be one hopper for one bag so faster than the normal counting machine. You can add the end weigher checker to ensure quantity accuracy.

1. Main transmission part
Consists of sealing CAM, small gear, signal wheel, and other components. Sealing CAM will show the action sealing and cut off through the tumbler working .small gear drive power to metering components, and the signal wheel will provide count signal and action time to PLC for pulling the bag.

2. Bag-pulling mechanism
It is controlled by the pulling motor, when you finished the bag length setting, the pulling step motor will be pulling the setting bag length that you set for the machine sealing and cutting.

3. Bag former part
Make from stainless steel 304. Different film widths will need different bags former

4. Film feeding part
The paper/film supply structure consists of film axes, film stepper motors, signal axis, and other components, it is primarily responsible for supplying and pulling packaging film to the packages. The signal axis is controlled by the sensor, when it gives the signal to the stepper motor, the stepper motor will give the running machine a cycle paper/film supply.

5. Sealing Mould adjustment
The distribution of the axial CAM driver  to the Photoelectric eyes, makes the drive shaft open and close periodicity, makes sealing work and  cutter open and  close action to achieve sealing and cut off

6. Photoelectric eye device
To choose the power switch of the packaging materials background, color control patch and photoelectric, please refer to the form.

The adjustment of the Photoelectronic Eye just to make sure the Photoelectronic Eye can correctly detect the color control patch, the requirement that the space between the Photoelectronic Eye and the color control patch is about 10mm, the indicator light will on when the color control patch detected by the Photoelectronic Eye, otherwise it is off, between the color of color control patch and film color, if the color is similar, you should adjust the sensitive adjustment of the Photoelectronic Eye. Each part adjustment
1. Speed adjust：
The machine speed has been adjusted slowly before they leave the factory. If you want to improve the packaging speed in the process of operation, you can adjust the knob. The speed should be determined by the bag-making, filling and sealing, and so on. On the contrary, the higher speed will be slowed down by turning left of the knob.2. Temperature adjustment
With different packaging materials, we should set the suitable temperature on the temperature controller. The general reference of temperature is as follows:

Packaging material	Fix temperature	Remark
Paper/polyethylene, nylon/polyethylene	130°C	These temperatures are only offered to reference. The concrete temperature should be depended on the effect of packaging and sealing.
Pt/PE	125°C
Pet/PE, BOPP/PE	120°C
Polypropylene/PE	110°C

The horizontal sealing temperature is always higher than the vertical sealing temperature by 10°C. After the temperature setting is suitable for the sealing, we can see whether the temperature is suitable or not. It cannot seal tightly if the heat sealing temperature is low; it will be folded if the temperature is high. Thus, we should have an adjustment on the temperature.

3. length adjustment of bag
When Packing material for proper installation, temperature suit for the sealing requirements,  input data on setting can be adjusted bag length.

4. former adjustment The installation of the bag former is required to be vertical to the packaging film/paper roll. And the mixture center line of the bag former will overlap with the vertical sealing bar. Otherwise, it may have the wrong side or fold. The front and back sides of the bag are former can ensure that the pulling bag wheel is pressed on the vertical sealing line.
Lose the bolts on the bag former, move to left or light to adjust the position of the bag former until it is set in the right place.

The bag is former and should be moved step right if the fault is like a right chart.
The bag former should be moved step left if the fault is like the left chart5. Cutter adjustment
Loose the screw and bolt of the left knife and right knife. the right cutter is floating and the left cutter is tied. At the same time, the right cutter and left cuter can be moved up and down.It can be an adjustment cutter spring by loose and tie screw. the working principle just like
scissors. loose or tie the springs for the pressure, and then tie the bolts back, start the machine to check the cutting, and make the adjustment until the cutting is good for your bags.

6. Heat sealing mold adjustment
Adjusting the heat sealing device require the left or right is flat on both side of the heat sealing device, and the left of the heat sealing device should face the center. We can move the position to adjust the vertical length of bag-making when the pressure is equal and vertical sealing is parallel to the fold of forming bag.
The method just like the picture is to lose the pull-tight screw slightly, so it can be moving and leaning around with facing the heat sealing device. Each heat sealing device has three screws which are to play the role of adjusting leveling and tightly. Each part can be adjusted when the screw rotates out or in by losing.
