Technical Field
The invention relates to the technical field of belt conveying, in particular to a magnetic conveying belt device with an electric control permanent magnet, which is mainly used for quickly conveying a coiled long steel belt after the coiled long steel belt is quickly cut into a fixed-length short steel belt by a flying shear.
Background
At present, the magnetic belt conveying device for conveying the steel belt is provided with two types, one type is an electromagnet conveying belt, the other type is a permanent magnet conveying belt, electromagnets or permanent magnets are arranged in the conveying belt, magnetic force penetrates through the steel belt and attracts the steel belt to convey the steel belt to a specified position, however, in the steel belt flying shear situation, the cutting speed of the steel belt is very high, the magnetic conveying belt matched with the steel belt also needs to have very high conveying speed to quickly convey or stack small steel belts after flying shear, and in the special occasion, the conventional electromagnets and the permanent magnets cannot meet the requirements.
The two magnetic conveying belts respectively have the defects that:
1. the magnetic conveying belt adopting the electromagnet is the most used technical scheme at present, advanced manufacturers such as Japan and Germany also use the belt all the time, and although the technology is mature and reliable, the belt has the defects of long-time electrification, high energy consumption, long-time heating of the electromagnetic coil, quick insulation aging, short service life and the like.
The belt is conveyed by adopting the magnetic force of the permanent magnet, the magnetic field of the permanent magnet is constant, the magnetic force cannot be controlled, the magnetic field is always arranged below the belt, the steel plate cannot be unloaded in a fixed length manner, and the belt is only suitable for occasions without unloading the steel belt during conveying and is not suitable for occasions for unloading the sucked steel belt after being conveyed to a specified station; even if a cylinder or a mechanical ejection mechanism is added to eject the steel belt to generate a gap between the steel belt and the permanent magnet conveying belt, the cost of the ejection mechanism needs to be increased and the abrasion and maintenance cost of the ejection mechanism need to be increased when the steel belt is dismounted, particularly in the steel belt flying shear situation, the conveying speed reaches 20m/s, and the speed of the ejection mechanism is difficult to meet the requirement.

The electric control permanent magnet mainly comprises an electromagnetic coil and a permanent magnet, and is characterized in that: the electromagnetic coil is internally provided with the permanent magnet, so that the bottom of the electric control permanent magnet always has a permanent magnetic field of permanent magnetic force, when the electromagnetic coil is electrified, the electromagnetic field is generated and counteracted with the permanent magnetic field of the permanent magnet, the bottom of the electric control permanent magnet loses magnetic force, and therefore, the attracted steel belt or magnetic conductive objects can be detached.
When the motor reducer drives the driving wheel to rotate, the conveying belt sleeved on the driving wheel can drive the driven wheel to rotate, a permanent magnetic field of permanent magnetic force is arranged at the bottom of the electric control permanent magnet, when a steel belt or a magnetic conductive object is close to the bottom of the electric control permanent magnet in the conveying belt, the steel belt or the magnetic conductive object can be attracted and conveyed, a plurality of electric control permanent magnets are arranged inside the conveying belt, after the steel belt is conveyed to a target position, the electromagnetic coil at the corresponding position is electrified to generate a magnetic field, the magnetic field is offset with the magnetic field of the permanent magnet, the magnetic force is lost at the bottom of the electric control permanent magnet, and therefore. The electric control permanent magnet can be demagnetized quickly when being electrified, and the permanent magnet magnetic field can recover the magnetic force quickly after being powered off, so as to meet the requirement of conveying short steel belts quickly in steel belt splitting occasions.
The permanent magnet adopts magnetic force irreversible permanent magnet (neodymium iron boron, ferrite, samarium cobalt magnet), also can adopt magnetic force reversible permanent magnet (alnico magnet).
As an improvement, the permanent magnet of the electric control permanent magnet can be formed by assembling a plurality of permanent magnets, namely a reversible permanent magnet and an irreversible permanent magnet.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
the problems that a magnetic conveying belt of an electromagnet is high in energy consumption and short in service life are solved, the permanent magnetic field adopted when a steel belt is conveyed to work is electrified for 1-2 seconds only when the steel belt is unloaded, the magnetic field of the electromagnetic coil and the permanent magnet are used for counteracting and demagnetizing, compared with the situation that the electromagnet is electrified uninterruptedly, more than 90% of energy is saved, the energy consumption is low, the electromagnetic coil cannot generate heat, and the service life is effectively prolonged; the invention also solves the problem that the permanent magnet can not lift the absorbed steel belt in a fixed size, the invention is internally provided with a plurality of groups of electric control permanent magnets, the electric control permanent magnets at corresponding positions can be controlled to demagnetize and lose magnetic force according to the conveying distance and the fixed size length of the sheared steel belt, the absorbed steel belt is lifted, the permanent magnetic field can rapidly recover the magnetic force after power failure, the speed of lifting the steel belt is higher than that of lifting the steel belt by adopting a jacking device, the efficiency is higher, the abrasion is less, and the magnetic conveying belt is used for rapidly conveying the steel belt after division shearing, and is energy-saving, rapid and less in abrasion.
