The surface of the copper roller is easy to damage and short in service life, and the quality of the sprayed belt is affected. The polishing device polishes the same part of the copper roller for a long time, so that traces, grooves and the like are polished on the surface of the copper roller, the surface roughness of the copper roller is deteriorated, and the belt manufacturing quality is seriously influenced.
And the cooling system of its copper roller constitutes complicacy, and the debugging is difficult, and operating stability is not enough, and at the operation in-process, its spring has been avoided not to receive its self unstability and equipment vibration influence and the unstable operating condition appears, and appears the end connection cooperation between its spring and the device that splines and appear stability and reliability scheduling problem equally easily, and the elasticity effort on its spring cross section is uneven moreover for static cover and the unbalance of hollow shaft end face sealing force under the spring force effect. This, on the one hand make the sound adapting unit wearing and tearing of rotary joint aggravate to make its life short, on the other hand, the unbalanced sealing plane frictional force leads to taking place easily and leaks, and again on the one hand to the adaptability of water supply pressure not enough, still on the one hand its elastic component fatigue factor etc. cause the unstability for the operation, and the debugging is difficult.
In yet another aspect, there is a need for further improvements and improvements in the structure and manner of operation of existing polishing apparatus. If there is certain irrationality in its structure of current burnishing device and corresponding operation mode, its cooling copper roller work wall receives influence such as adhesion stereoplasm granule and dirty scaling thing, bits easily, and polishing effect is poor on the one hand, and on the other hand needs frequently to carry out manual cleaning to cooling copper roller surface, causes the working face of copper roller can not satisfy the production technology requirement, seriously influences and spouts the area quality, influences and spouts the normal operating of area equipment, influences and spouts area production efficiency.

Detailed Description
In order to better understand the technical solution of the present invention, the present invention will now be described clearly and completely by embodiments with reference to the accompanying drawings.
The invention relates to a tape spraying device and a tape spraying and manufacturing method, wherein the tape spraying device comprises: the strip-spraying and strip-making are implemented by a moving copper roller relative to a nozzle in an intelligent dynamic strip-spraying mode simulating a human.
The permanent magnet synchronous polishing device or system polishes and polishes the copper roller by a simulation method of simulating the back-and-forth displacement of a human.
As shown in fig. 1-3. The intelligent simulation strip spraying equipment for the ultrathin soft magnetic silicon steel sheet comprises a rack 40, a copper roller 20 arranged on the rack 40, a copper roller polishing device, a copper roller cooling system, a medium-frequency induction heating furnace 27 fixed on the rack, a nozzle 27a of the medium-frequency induction heating furnace and the like. The frame 40 is connected to a cantilever 40a, on which the intermediate frequency induction heating furnace is disposed, through a column at one end thereof. An automatic opening/closing type support device is provided corresponding to the arm 40 a. The automatic separation and combination type supporting device comprises a transverse telescopic driver 29 arranged on a stand column at the other end of the machine frame, a guide sleeve 25 and a conical tip connecting and positioning shaft 25a connected between the telescopic driver and the conical connecting sleeve 24 at the free end of the cantilever through the guide sleeve. When the intermediate frequency induction heating furnace is in load operation, the telescopic driver 29 is controlled by the corresponding controller to enable the conical tip connecting and positioning shaft 25a to extend out to be matched and connected with the corresponding conical connecting sleeve 24 so as to position and strengthen the cantilever.
The copper roller, the cooling system of the copper roller, the polishing device of the copper roller and the like are arranged on the sliding rack. A track device is arranged between the sliding rack and the frame.

The intermediate frequency induction heating furnace 27 and the nozzle 27a are provided to a cantilever 40a of the gantry. The skid 50 is provided to the frame 40 by a rail device 51. A piston cylinder or a servo-driven electric telescopic rod is connected between the skid 50 and the frame 40. The skid 50 is movable back and forth in the copper roll axial direction with respect to the nozzle 27a on the intermediate frequency induction heating furnace 27 by its rail device 51.
Under the control of a corresponding controller, when the copper roller 20 works, the copper roller can move back and forth continuously or intermittently at a certain speed and frequency relative to the nozzle 27a along the axial direction of the copper roller through the sliding frame and the rail device thereof, and the different parts of the surface of the copper roller correspond to the nozzle to carry out rotary throwing belt manufacturing. That is, during operation, the copper roller continuously or intermittently changes its position of rotation at a constant frequency and speed. The device can prevent the copper roller from running at the same position all the time or for a long time and receiving the sprayed liquid of the nozzle to be whirled, thereby effectively protecting the copper roller from being damaged and damaged due to local overheating during running, and preventing the copper roller from influencing the surface smoothness and further influencing the quality of a sprayed belt due to local overlong time running.

The rotor 102 is fixed to the corresponding bracket by its fixed shaft 104. In this example, the bracket includes an adjustment bracket 44 and a rocker arm bracket 43 (depending on whether the lapping wheel 1 is located on the front or back side of the copper roller). The stator is rotatably connected to the rotor 101 or its hub 1b via a bearing 103, and the laminated grinding wheel (or laminated grinding wheel portion) 1a is fixedly connected to its hub 1 b.
Namely, compared with the existing corresponding permanent magnet synchronous motor, the permanent magnet synchronous motor structure and the corresponding operation mode are equivalent to that of the following steps: the structure of the corresponding rotor is set to be similar to the structure of the stator and the two end covers (or the pipe body and the two end covers), and the structure of the corresponding stator is set to be similar to the structure of the rotor (or the cylinder). The permanent magnet and the armature winding are respectively arranged on the corresponding rotor similar to the stator and the two end covers or the tube body thereof and the corresponding stator similar to the rotor or the cylinder.
The relative two-side shell body of the corresponding rotor of the similar stator and the two end covers or the tube body and the two end covers of the similar stator is provided with a corresponding shaft hole, the relative two sides of the corresponding stator of the similar rotor or the cylinder-shaped structure are respectively provided with a cylinder-shaped protruding end which corresponds to the shaft hole and is positioned on the axis, and the cylinder-shaped protruding end forms a fixed shaft of the corresponding stator of the similar rotor or cylinder-shaped structure.
