The chuck closing failure of high-speed automatic wire cutting machines has troubled many users. PHP editor Apple found that this problem often occurs after the machine has been used for a period of time, causing the thread cutting to fail to proceed normally. In order to help you solve this problem, the editor will introduce the cause of the fault and the solution in detail below, and guide you to quickly restore the machine to normal operation.
Usually the cylinder is broken, just replace it. We all know that the automatic wire cutting machine is a wire end processing equipment. This equipment can handle short wires within 50MM that were previously considered difficult to process, and even the total length is only 1MM. At the same time, both ends can also be stripped 0.3MM at the same time. The performance of a computer wire cutting machine is directly related to the machine's wire stripping production efficiency. It is very important to understand the production process of the wire cutting machine and the problems encountered
The specific operation method should be operated according to the manual of the paper cutter. The safe operating procedures are as follows:
1. Before starting the machine, you should check the machine, clean it, add engine oil or butter, test the empty knife three times, and observe Whether there is a knife back, if any problem is found, it should be eliminated in time. During the production process, if a knife is found to be back, the machine should be stopped immediately and repaired in time to prevent it from running sick.
2. When working, the mind must be concentrated. It is strictly forbidden for two people to operate the paper cutter at the same time.
3. When the machine is running, it is strictly forbidden to put your hands into the machine. If a malfunction occurs, you are strictly prohibited to use your hands to grab the paper. The machine should be stopped immediately. The paper cutter does not return enough to stop, so you cannot reach out to pick up the paper. 4. When adjusting and replacing the paper cutter, the machine must be stopped. Even when the machine is stopped, it is strictly forbidden to put your hands under the knife to change the knife. Long-handled bolts and other tools should be used to change the knife. They must be removed during test run to avoid injuring the operator when the machine is started. 5. The power must be cut off when adjusting the machine, replacing blades, repairing, refueling, scrubbing and inspection.
There may be several reasons why the wire cutting machine keeps cutting:
1. Tool wear: The cutting tool of the wire cutting machine may wear out after being used for a long time, resulting in reduced cutting capacity and inability to cut the wire smoothly. You can try to replace the tool with a new one.
2. The material is too hard: If the wire material being cut is too hard and exceeds the tolerance range of the wire cutting machine, it will cause continuous cutting. At this time, you need to choose a suitable wire cutting machine model or replace it with a more powerful machine.
3. Improper setting of cutting parameters: The cutting parameters of the wire cutting machine need to be adjusted appropriately according to the material, thickness, etc. of the wire. If the parameters are set improperly, too high or too low may cause continuous cutting. Parameters can be adjusted according to the wire condition.
4. Failure or mechanical problems: The wire cutting machine may have malfunctions or mechanical problems, such as transmission damage, motor failure, etc., resulting in continuous wire cutting. At this time, machine faults need to be checked and repaired.
5. Improper operation: The operator may perform improper operation during the operation, resulting in continuous thread cutting, such as cutting the thread too fast, not strong enough, etc. During operation, you need to follow the operating procedures and adjust the operating skills appropriately.
If the problem of continuous thread cutting still cannot be solved after the above exclusions, it is recommended to contact professional equipment maintenance personnel for inspection and repair.
The fully automatic multi-functional computerized wire cutting machine is a high-end equipment, and its operation and adjustment require certain skills and experience. Here are some adjustment methods for reference:
1. According to the specifications of the wire, select the appropriate cutting knife mold to ensure cutting quality.
2. Set the cutting length and speed, which can be adjusted according to the material and thickness of the wire. Note that the speed cannot be too fast or too slow.
3. Set the wire pulling speed and tension to ensure that the wire will not break or deform before and after cutting.
4. Check whether the cutting die and cutting blade are worn, and replace them if necessary.
5. Pay attention to cleaning and lubricating equipment to ensure normal operation of the equipment.
6. Choose different cutting methods according to your needs, such as single cutting line, multiple cutting lines, etc.
7. Calibrate equipment parameters, such as setting initial cutting line length, pressure, speed, etc.
8. Check whether the circuit and program settings are correct and make adjustments if necessary.
It should be noted that since different equipment brands and models are different, the above adjustment methods are for reference only, and specific operations must be carried out according to the equipment manual and technical guidance. If necessary, you can ask professional maintenance personnel to adjust and maintain it.
Common troubleshooting solutions for automatic wire stripping machines
The wire end cannot be stripped
1. Check the cutting depth of the wire and adjust the wire diameter to become smaller.
2. The gap of the incoming line transmission wheel is too large. Adjust the gap of the incoming line transmission wheel.
3. Whether the stripping head setting is greater than 2mm.
4. There is something stolen in the inlet pipe.
5. The retraction setting is too large and needs to be reduced.
The automatic cutting bed is an automated equipment that replaces manual cutting and is a representative of automated clothing equipment. Many people who come into contact with a cutting bed for the first time always think that spreading and cutting are the same. In fact, this is not the case. The function of the automatic cutting bed is cutting, and spreading is another spreading machine or assisted by manual spreading.
After sewing, if the thread automatically pulls back after trimming and becomes loose.
It has an automatic knotting function, which can be used before stopping the needle.
Then there is an automatic thread trimming function, follow this function directly.
No matter where the line is, it won’t come loose.
If you don’t have the above functions.
When tightening the stitches, return three stitches as a fixation.
Even if the upper thread is pulled back, it will not come loose.
Also, please adjust the lower thread tension. If it is too tight, it will easily pull back.
Repair method
1. First make sure that the machine can be powered on, can be turned on, and can move the needle normally.
2. Then look at the machine body to see if there is a button to lift the presser foot.
3. If yes, stop the needle at the normal position and press the button to lift the presser foot.
4. Continue to look at the machine body to see if there is a button to adjust the needle stop position.
5. If so, adjust the needle stop position to the needle stop position at the top.
6. If you have the above and still cannot lift the presser foot normally after following the instructions, please report it for repair.
7. If none of the above are available, please manually turn the needle to see if the presser foot can be raised, and stop at a high position in time for normal replacement of the presser foot.
8. If the needle moves abnormally during manual operation and cannot be improved, please report it for repair.
1) The pressure of the upper roller is too small, adjust the pressure nut and increase the pressure
2) The fixing screw of the feeding motor is loose, tighten the screw
3) The top screw of the lower roller pulley is loose or the top screw of the feeding motor pulley is loose , lock the top screw
4) Cut more than two pieces at the same time, and when the two cut lengths are different, adjust the pressure on both sides of the upper roller to make the two cut lengths equal.
5) If the feeding motor vibrates when feeding, instead of moving smoothly, it means the drive box is faulty. Please replace the drive box with a good one.
