Straight-feed Wrap Sleeve Shrink packing machine, unique linear design with compact structure covers an area, in view of some limited sites and no need to adjust the direction of the product in the packaging process, it is very convenient, and can work independently without the limitation of the length of the package. Work together with constant heat shrink tunnel it can be docked with the production line for automatic feeding, film wrapping and sealing, overall shrink wrapped. Widely used in food industry, daily necessities, beverage, cosmetics, printing, hardware, furniture, toy and other industrial products.
Sleeve shrink packing machine refers to the product with a single layer of film horizontal wrapping after constant temperature shrinkage paste wrapped in the product surface, to play a dust-proof, moisture-proof, anti-wear of a kind of packing equipment; most use LDPE shrink film, because of its toughness and strength is high, of course, according to the actual demand can also choose POF and PVC film, etc.; as a result of shrinkage at both ends of the side will be round-shaped opening (not fully closed), because it is called sleeve shrink packing machine.
Its working process is relatively not too complicated, because it only needs to seal unilaterally, but it also needs to master the correct operation methods and matters needing attention, so as to ensure that it can adapt to the packaging requirements of many different sizes and stable long-term work efficiency. Please let SNCPACK share some of the main adjustments and points for attention of one of the most popular straight-feed wrap sleeve shrink packing machine:
1. Select the width and thickness of LDPE film and install the film rolls correctly
According to the characteristics of most shrinking films in the market, the width of the film is mainly selected in the following ways:
A. The width of the film = the length of the product + 2/3 height of the product, when the height of the product is below 10cm
B. Width of the film = length of the product + height of the product, when the height of the product is on 10cm
Please note: since the film opening of most products after packaging is toward one side of the width of the product, the width of the film should be selected according to the length of the product.
If the weight of the product is less than 5 Kgs, the thickness of the film can be less than 60 microns, 5 Kgs to 15 Kgs, 60 to 80 microns, more than 15 Kgs, and more than 80 microns.
2.Adjust the sealing and cutting height and pressing height;
This equipment can adjust the height of the sealing knife according to the height of the product to ensure that the sealing tangent is in the central position of the product (better shrinkage effect). Then adjust the position of the press, which is used to press the wrapped product during sealing and cutting. prevent product retreat and ensure that the film is better sealed;
3.To adjust the photocell position, the sealing and cutting delay position can be set in the PLC program, but sometimes it is necessary to adjust the photocell fixed position because the product size is too large and reaches the maximum speed.
4.Adjust the speed of the conveyor belt; because of the pneumatic control used in sealing and cutting, its speed is fixed, so the speed of the machine is mainly adjusted to control the frequency converter of the transmission. It is not recommended for non-professionals to adjust the parameters, just rotate the button to adjust the transmission power. SNCPACK will lock the main parameters when the machine leaves the factory to prevent the core parameters from being confused due to miss operation; please contact the SNCPACK professional engineer if necessary.
5.Always keep the use site clean and tidy, and ensure that the working ground is flat; a good use site and a stable working table are necessary conditions to ensure the long life of most of the machinery and equipment.
The above are the main operating items of this straight-feed wrap sleeve packing machine made by SNCPACK. We will regularly update the operation mode and precautions of other parts of our equipment.
