1. Sealing machine use range and performance:

Large factories and warehouses, for food, sugar, salt, food, fertilizer, chemical products and other items of canvas bags, sacks, flour bags, woven bags, paper bags of work.

The single-chain chain stitch stitched by this machine has the advantages of beautiful appearance, firm package, flexibility and unpacking convenience.

Second, the structure of the packet machine

GK9The machine is made of aluminum alloy die-casting and has good mechanical properties.

Main technical parameters

Model: GK9-2 Spindle speed: 800r / min Pitch: 6-8MM Adjustable suture specifications: 2 * 3 shares of envelope Power: 90W GW, net weight: 4.5KG / 3.8KG

Fourth, the sealing machine use and adjustment methods:

Sewing machine operation method: sewing machine operation method is simple, as long as the line put on, lift the machine to be sewing the bag, press the switch can be sewing work.

(A) the replacement of the needle

(1) Turn the handwheel clockwise so that the needle is raised to the highest position 8X10Mm double-headed wrench unscrew the needle nut, you can pull out the needle, put on a new needle, you must pay attention to the direction of the needle. Outline of the groove, the gap inward, and to be inserted into the needle needle Press the top of the needle and then tighten the needle nut.

(2) Threading step

Pull out the thread on the wire frame, through the wire on the back of a hole and the hole, around the pressure plate, and then into the C hole, through the needle rod tail hole, along the panel down from the needle Of the trunking positive penetration needle needle hole, pull out unclear about 90~100Mm thread, you can sewing.

Illustration:

(3) Line specifications and line selection methods

The machine is intended for use 21S/12~18Strand or nylon thread, etc. The thread is to be wound on a cone-shaped spindle, which is fixed with a wire-nail cap after being put in the bushing, but the thread which is spun into the fiber must meet the following requirements. You can ensure that the sewing performance should be. Users want to be selected when the suture attention.

1. Suture should be consistent, uniform thickness, no scarring and knot.

2. Soft and smooth surface, no hair, and have a certain toughness and tension.

3. Uniform twist can not have a large force exists.

(4) Suture pressure adjustment

Suture pressure is the main factor affecting the tightness of the stitch.If the suture pressure is too weak, so that after sewing thread braid loose.Package after the bag is easy to produce loopholes, if the suture pressure is too strong will So that the lack of elasticity of the line braid to make crepe pocket, when the bear greater momentum, the line will produce burst braided bulk package.

The principle of suture pressure adjustment should be to reduce the pressure on the thick tight seam, the thin seam should increase the pressure in the use of need to increase or decrease the suture pressure, just tighten or loosen the back of the line nut.

Five. Packet machine needle and crochet of mutual correct position

The mutual position of the needle and the crochet is correct or not, which directly affects the sewing performance of the machine.

1. Needle down to the lowest point, the crochet needle and needle center distance 3.5Lt; / RTI & gt;0.2Mm

2. When the crochet hook into the needle thrown by the coil ,The crochet plane is in close contact with the notch plane of the needle ,The gap in the 0.1~0.18Mm ,The distance between the lower part of the crochet tip and the upper part of the needle thread hole is 2~2.5Mm .The distance between the top of the crochet tip and the bottom of the needle plate is 2~2.5Mm

3. Crochet stopped at right ,When the needle falls into the loop of the crochet ,Crochet back and needle center distance 1.5Lt; / RTI & gt;0.2Mm

six .A Method for Adjusting the Location of Needle and Crochet

(1)Head from the bottom of the needle plate in general 2~2.5Mm ,When the hook hex screws (65)Loosen ,Can be crochet Down ,To be adjusted ,Tighten the inner six screws firmly.

(2)Crochet and machine needle mobility ,When the gap is too large or when the needle ,You can loosen the hexagon nut and the hexagon nut, and screw in or out of the set screw .The gap can be reduced or increased ,When the adjustment is completed, the hex nut must be firmly locked.

Seven .Adjusting method of feeding height

The height of the surface of the needle plate exposed by the feed teeth is determined by the nature and thickness of the seam material. 1.5~2Mm. After the tooth tip of the feed teeth is worn, it is often possible to feed normally. When adjusting the tip or replacing the new feed teeth, adjust the height of the feed teeth to expose the plane of the needle plate.

Adjust the method: Turn the handwheel to the highest position of the cam on the dental device. Place the feed tooth into the dental device, screw the screw, and expose it to the tooth surface of the feeding tooth 1.5~2Mm when ,And then tighten the screw force.

Eight lines cut off the line braid:

In order to prevent the stitches from loosening, when sewing the bag, the two ends of the bag should be left 50In order to prevent the braid from spreading or being pulled off

After sewing a bag, we should continue to lead the braid and cut the braid on the cutting knife, 50Mm line braid

9. Sealing machine safety and maintenance knowledge

Safety Precautions:

Since the machine is in direct contact with the power source, the owner must pay attention to safety. Before using the machine, pay attention to the following points:

1. Before use, should first check whether the power supply and the motor provides the input voltage match.

2. For safety reasons, a three-wire power cord with a grounding wire must be used /Yellow two-color one for the ground wire, and to regularly check the internal wiring and insulation of the machine.

3. When used in wet places, wear rubber shoes and wear insulated gloves.

4. In the cleaning or use, the oil does not flow into the electrical parts.

5. Brush the motor and the cable jacket is worn, the need for timely exchange.

6. Use of environmental conditions, relative humidity is not greater than 85%; Non-flammable gas sites.

7. When the packaging material is conductive, please be careful to pay attention to safety.

10. Sealing machine maintenance knowledge:

1. When the machine is newly purchased or not used for a few days, it should be added to the sewing machine oil in the whole oil hole. After half a minute, the oil can penetrate the machine before it can start working, and refueling is not less than three times a day.

2. After the work of each class, the machine must clean up the part of the crochet and feeding mechanism, especially when the machine is cleaned, and lift the feet in the capacity of the diesel fuel for several minutes, then inject the sewing machine oil for several minutes, And the grease in the pan seat is changed every three months.

3. Motor brush wear, the timely exchange.

4. When not in use, please place the machine in a dry and ventilated place.

Use is to plug in the power, press the button you can use, cut, then some people do not know that with scissors cut, in fact, not used, the back of the iron can cut thread, so very convenient. Refueling in the regular activities of the local refueling, the general oil can also rely on the maintenance of the machine, if you maintain a good life will grow a lot.
