Common faults and solutions of tufting machine
The transmission structure of the high-speed toothbrush tufting machine is composed of the main drive shaft and four servo drive shaft systems. The four servo axes are horizontal X axis, vertical Y axis, flap Z axis and molt U axis. The XY two-axis coordinates determine the position of the toothbrush hole, the Z-axis plays the role of changing to the next toothbrush, and the U-axis plays the role of changing the hair color of the toothbrush. When the main shaft motor is running, the four electronically controlled servo axes will run accordingly, and when the main shaft stops, the other four axes will stop accordingly. The speed of the main shaft determines the speed of the hair planting, and the four servo axes respond to the requirements of coordinated drive, otherwise there will be hair removal or uneven hair. Application of Delta Dentsu's high-precision electrical servo control can achieve 1000 times/min hair planting speed, and can achieve jumping hole hair planting.
At present, the structure of the electrical control system of the tufting machine is mainly divided into a single-chip microcomputer control system or a CNC numerical control system. Among them, the single-chip microcomputer control system is mainly based on the integrated supporting services of automation system manufacturers, and the independent research and development of toothbrush equipment manufacturers is supplemented. Most of the CNC numerical control systems with superior performance are Delta's PUTNC-H2P and imported brands such as Europe and Japan.
Because the signal hold time of the needle barrier parking of this device will be relatively short (minimum 5MS), in order to achieve the effect of fast parking, the system may not be able to respond to the signal without giving a corresponding message on the screen Reminder, so once the user finds that the device does not have any reminder information, the task is aborted and the display“The equipment is in normal operation”And the running indicator light is also on, which can be directly judged as the needle barrier parking or the needle barrier sensor failure.
The tufting machine is a tufting processing equipment for various brush products such as toothbrushes, hair dye brushes, hair combs, wire
brush machine factory, fruit washing machine roller brushes, and sanding brush rollers. It was a hand-operated tufting machine at the earliest, and later developed into an electric tufting machine. With the development of automation, various computer numerical control high-speed tufting machines have been developed.
The machine head is the main mechanical part of the tufting machine. The main actions of tufting are: picking up the wool, cutting the thread, forming the iron wire, binding the brush wire with the iron wire, and implanting the brush wire into the hole. The machine head mainly realizes the above main actions through the connecting rod and cam structure. Equipment positioning accuracy, such as: positioning accuracy of the workbench, whether there is a gap in the mechanical structure, the repeatability of the process from slow to fast, what kind of pusher and motor are used for the control system, etc.
Do a good job in the daily maintenance of the equipment, keep the equipment clean, clean up dust, sundries, and waste materials in time, add lubricating oil in time, and do a good job in anti-wear and anti-rust work. Regularly check vulnerable parts and replace excessively worn parts in time to avoid affecting product quality due to parts wear. Regularly check equipment lines and replace worn lines in time.
The operator should often add lubricating oil to the moving parts of the tufting machine to reduce mechanical wear. Regularly check whether the screws are loose and tighten them in time. Keep the guide rail and screw rod clean to avoid debris adhering to the guide rail or screw rod, which will affect the accuracy of work positioning. Ensure that the electric box works in a ventilated environment, avoid humid or high temperature environment, and prevent the electric box from violent vibration. The electrical box cannot work in an environment with strong electromagnetic fields, otherwise uncontrolled conditions may occur.
The four servo axes are horizontal X-axis, vertical Y-axis, flap Z-axis and moulting U-axis. The XY two-axis coordinates determine the position of the toothbrush hole, the Z-axis plays the role of changing to the next toothbrush, and the U-axis plays the role of changing the hair color of the toothbrush. When the main shaft motor is running, the four electronically controlled servo axes will run accordingly, and when the main shaft stops, the other four axes will stop accordingly. The speed of the main shaft determines the speed of the hair planting, and the four servo axes respond to the requirements of coordinated drive, otherwise there will be hair removal or uneven hair.
