TECHNICAL FIELD
[0001] The utility model relates to strip steel oiling rust prevention technical field, concretely relates to a static electrostatic oiling machine oiling amount control device. BACKGROUND
[0002] The oiling machine is a kind of machine for producing and manufacturing oiling equipment, and the main purpose is to coat a layer of high-quality paint or other coating on the surface of material to protect the material and improve the aesthetic appearance. There are many types of oiling machines, which can be widely used in furniture, building materials, paper printing and other industries. Some oiling machines are equipped with drying machines or UV accelerated curing equipment to improve the color and hardness of the coating. With the development of the market and the continuous improvement of people's quality of life, efficient and pollution-free surface cleaning and oiling technology has become an important technical development direction in the steel industry. Cleaning and oiling have become an important processing procedure to ensure that the final product not only has good appearance and smoothness, but also can prevent rust.
[0003] The earliest oiling equipment for strip steel surface is a traditional roller type oiling machine. The traditional roller type oiling machine is a contact type oiling method, which includes rollers, pads, brushes and other coating methods. The oiling amount of this traditional roller type oiling machine is large and uncontrollable, which leads to serious pollution, and the strip steel also has the phenomenon of oil overflow. Therefore, a static electrostatic oiling machine appears. The common static electrostatic oiling machine is composed of an oiling chamber, a high-voltage static power supply, an oil supply system, an oil circuit heating and circulating system, an electric control system and an operation table. The oiling knife beam is installed above the oiling chamber, and the transport roller is installed in the oiling chamber. The steel plate can pass through the transport roller at a constant speed from the oiling chamber. The oil supply system provides oil to the oiling knife beam in a quantitative manner, which flows out uniformly from the knife opening gap of the knife beam. The high-voltage static power supply outputs about 100KV negative direct current high voltage, which is applied to the oiling knife beam to generate a high-voltage static field between the knife beam and the steel plate. The oil with negative charge is atomized and adsorbed on the surface of the steel plate in the high-voltage static field to form an oil film, which plays a role in rust prevention.
[0004] Although the static electrostatic oiling machine has the characteristics of low oiling amount, uniform and controllable oiling and good adsorption compared with the traditional roller type oiling machine, it is necessary to package the strip steel in the production process of the strip steel. When the strip steel is cut, the strip steel stops running at a reduced speed. Before and after the cutting, the strip steel accelerates or runs at a low speed, and the oiling amount is still greater than that when the strip steel runs at a constant speed in the middle section, which affects the overall oiling amount of the strip steel and leads to the problem of poor welding quality of the strip steel product downstream user due to the thick oil film of the strip steel. Therefore, we propose a static electrostatic oiling machine oiling amount control device to solve the above problems. UTILITY MODEL CONTENTS
[0005] The purpose of the utility model is to provide an electrostatic oiler oiling amount control device to solve the problem that when the running speed of the strip steel coil is low, the oiling amount is too large, resulting in a thick oil film, thereby causing poor welding quality when downstream users perform coil welding.
[0006] To achieve the above-mentioned purpose, the basic solution provided by the present invention is: an oiling amount control device for an electrostatic oiling machine, comprising an oiling chamber and a tension roller, the oiling chamber being located above the tension roller, the tension roller being electrically connected to an encoder, a tool holder being fixedly connected above the oiling chamber, the tool holder being provided with a spray knife, a first guide plate being bolted to the oiling chamber, a groove being provided on the first guide plate, a second guide plate being clamped in the groove, two metal wires being fixedly connected to the first guide plate, a metal sheet being fixedly connected to the first guide plate, the metal sheet being connected to one end of a metal wire, a first cylinder being fixedly connected to the first guide plate, the first cylinder being located on one side of the metal sheet, a grounding wire being fixedly connected to the telescopic end of the first cylinder, a PLC controller being electrically connected to the first cylinder, and the PLC controller being electrically connected to the encoder.
[0007] The working principle of the utility model is that when the strip steel runs on the tension roller, the encoder on the tension roller can monitor the speed of the strip steel in real time and transmit the data to the PLC controller. When the running speed of the strip steel is lower than the set value of the PLC controller, the first cylinder is first started by the PLC controller, and the cylinder rod of the first cylinder extends out to contact the metal sheet, so that the metal wire connected to the metal sheet is grounded, and then the grounded metal wire can absorb a part of the charged oil mist sprayed by the spray knife, thereby reducing the amount of oil applied to the strip steel.
[0008] The beneficial effect of the present invention is that: the present invention arranges a metal wire under the spray knife to absorb grease, so that the amount of oil applied can be controlled when the strip runs too slowly. Compared with the electrostatic oiler under the existing technology, this design can control the amount of oil applied to the strip when the running speed of the head and tail of the strip coil is too low, thereby avoiding the problem of poor welding quality when the downstream users of the strip product perform coil pipe welding due to the thick oil film on the strip.
[0009] Option 2 is the preferred option of the basic option. The spray knife and the knife holder are connected by bolts. The user can adjust the angle of the spray knife according to the different requirements of the oil coating amount of the strip, which is easy to use.
[0010] Option three is the preferred option of the basic option. The second guide plate is tilted outward by 20°-30°. The tilt of the guide plate can drain the grease on the guide plate, making it easier to collect the grease.
[0011] Scheme four, this is the preferred basis of the scheme, the oil room is provided with a second cylinder, the second cylinder and PLC controller are electrically connected, the telescopic end of the second cylinder is fixedly connected with a vertical rod, the vertical rod is fixedly connected with a baffle, the baffle is located above the second guide plate, when the oiling machine is used up, the baffle can be moved to the lower side of the spray knife through the second motor, so as to prevent the oil on the spray knife from dropping to the lower side.
[0012] Scheme five, this is the preferred basis of the scheme, the second guide plate is provided with a flow guide groove below, for collecting the oil on the second guide plate.
[0013] Scheme six, this is the preferred basis of the scheme, one end of another metal wire is fixedly connected with a resistor, the other end of the resistor is grounded, and the resistor can make the oil mist sprayed by the spray knife more dispersed, so that the oil mist is better attached to the strip steel.
