Description

Technical Field

[0001] The present invention relates to a magnetic strip thin ribbon spraying device, and in particular to an adaptive automatic balancing circulating cooling system. Background Art

[0002] The existing magnetic strip thin tape spraying device has a relatively static nozzle and a rotating strip-spinning roller. This type of strip-spinning device has certain irrationalities in its overall structure, including the nozzle structure, pressure, speed, and the clean, smooth, and cooling effect of the working surface of the strip-spinning roller, which have a very important impact on the quality of the strip. In particular, the matching structure and operation mode of the strip-spinning roller and the nozzle are extremely irrational, making the strip-spinning roller surface easily damaged and short-lived, and affecting the quality of the strip. It is particularly difficult to implement dynamic circulation cooling for a multi-directional operation device that is also in mobile operation while rotating. The cooling system of the strip-spinning roller used in the existing device is complex, difficult to debug, and lacks operational stability. During operation, the spring of the dynamic sealing device of its spring and other structures is inevitably affected by its own instability and equipment vibration, resulting in an unstable operating state. The end connection between the spring and the anti-rotation device is also prone to problems such as stability and reliability. Moreover, the elastic force on the spring cross section is unbalanced, making the sealing force between the stationary sleeve and the hollow shaft end face unbalanced under the spring force. On the one hand, this causes increased wear on the dynamic and static connection parts of the rotary joint, thus shortening its service life. On the other hand, the unbalanced friction force on the sealing surface makes leakage easy to occur. On the other hand, it is not adaptable enough to the water supply pressure. On the other hand, the fatigue factor of its elastic parts causes unstable operation and difficulty in debugging. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides an adaptive automatic balancing circulating cooling system. The adaptive automatic balancing circulating cooling system has a simple and reasonable structure, excellent overall structural performance and good cooling effect.

[0004] The technical solution of the adaptive automatic balancing circulating cooling system of the present invention includes a dynamic sealing connection device, which includes a connecting sleeve and a stationary ring arranged in the inner cavity of the connecting sleeve. It is characterized in that it also includes a piston device, the stationary ring is connected to the inner wall of the connecting sleeve through a seal, the connecting sleeve is connected to the hollow shaft through a bearing device, and the hollow shaft and the stationary ring form an end face friction seal connection with each other.

[0005] The end faces of the hollow shaft and the stationary ring are respectively inlaid with alloy or ceramic rings, and a friction seal connection is formed between the hollow shaft and the stationary ring via the alloy or ceramic rings.

[0006] The self-adaptive automatic balancing circulating cooling system and the spray belt device thereof of the present invention have simple and reasonable overall structures, are easy to use and operate, have high cooling efficiency and good effects, and are helpful to improve the quality and efficiency of spray belt production.

[0007] Its adaptive automatic balancing circulating cooling system has a good dynamic sealing effect. On the one hand, its cooling cycle is smooth, which can adapt to the dynamic sealing cooling of the belt-spinning roller's rotation, and at the same time realize the dynamic spray-varying sealing cooling of the belt-spinning roller's movement. Through the organic and reasonable combination of its dynamic sealing connection device and the telescopic sealing coupling device, it can simultaneously meet the multi-directional three-dimensional dynamic change water supply cooling of the belt-spinning roller's rotation and axial movement, with low circulation resistance. On the other hand, it can also adapt to the pressure changes of the circulating water supply adaptive automatic balancing circulating cooling system and automatically feedback adjust, which can maintain the long-term stable and reliable operation of the automatic water cooling system. The dynamic and static coordination is balanced, stable, and reliable, with a long service life. Its debugging is particularly simple or even requires no debugging. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] In order to better understand the technical solution of the present invention, the present invention is now clearly and completely described through embodiments in conjunction with the accompanying drawings.

[0010] The tape spraying device of the present invention implements tape spraying and making in a dynamic tape spraying manner through a moving tape throwing roller relative to a nozzle.

[0011] like Figure 1 As shown. The self-adaptive automatic balancing circulating cooling system of the present invention includes a dynamic sealing connection device 22, a cooling inner cavity 21 provided in the belt-spinning roller, and an inner cavity of a hollow shaft 19 connected to the sliding frame 50 through a corresponding bearing device. The belt-spinning roller 20 is fixedly connected to the hollow shaft. A guide inner cylinder 23 connected to the hollow shaft is provided in the cooling inner cavity of the belt-spinning roller. The dynamic sealing connection device 22 includes a rotary joint similar to that of the prior art.

[0012] The hollow shaft's inner guide tube is provided with water inlet holes 21a and water outlet holes 21b on either side, communicating with the cooling cavities on both sides. The water inlet and outlet holes of the hollow shaft 19 are connected to the water inlet or outlet of the dynamic sealing connection device 22, respectively. The belt-spinning roller adaptive automatic balancing circulating cooling system also includes a telescopic sealing coupling device, through which the adaptive automatic balancing circulating cooling system or device is connected to the cooling water source or its circulation loop. The telescopic sealing coupling device is an elastic pipe connector 28. One of the two elastic pipe connectors 28 has one end connected to the water inlet of the dynamic sealing connection device 22 via a transition cooling channel 53 provided on the carriage, and the other end connected to the cooling water source outlet. The other elastic pipe connector 28 has one end connected to the water outlet of the dynamic sealing connection device 22 via a transition cooling channel 53 provided on the carriage, and the other end connected to the cooling water source return port. The telescopic sealing coupling device or its elastic pipe connector is suspended from the frame, allowing for integral movement. The cooling water source is installed on the frame or an external static cooling water source is introduced.

[0013] The belt-spinning roller is equipped with a balanced cooling system comprising balanced cooling holes 23a distributed throughout the guide inner tube 23. These holes 23a are distributed along the sidewalls of the guide inner tube and connect to the cooling cavities (interlayers) on opposite sides of the belt-spinning roller, which are divided by the guide inner tube. This balances the heat exchange efficiency of the entire belt-spinning roller. This system not only refluxes the cooling water flow, expanding the effective flow area and increasing the effective cooling medium flow rate, significantly improving the cooling effect, but also significantly reducing the circulation resistance of the cooling medium and lowering power consumption.

[0014] During operation, cooling water flows from the cooling water source through the water inlet at the corresponding end of the hollow shaft into the cooling inner cavity on one side of the guide inner cylinder of the belt-spinning roller, and then flows back to the cooling water source from the cooling inner cavity and the water outlet on the other side of the guide inner cylinder.

[0015] The belt spraying device includes a frame 40, a belt-spinning roller 20 arranged on the frame 40, a belt-spinning roller polishing device, an adaptive automatic balancing circulation cooling system for the belt-spinning roller, and a medium-frequency induction heating furnace and its nozzle fixed to the frame. The frame 40 is connected to a cantilever through a column at one end, and the medium-frequency induction heating furnace is arranged on the cantilever. An automatic split-and-close support device is provided corresponding to the cantilever. The automatic split-and-close support device includes a transverse telescopic drive arranged on the column at the other end of the frame, a guide sleeve, and a cone-tip connection positioning shaft connected between the telescopic drive and the conical connecting sleeve at the free end of the cantilever through the guide sleeve. When the medium-frequency induction heating furnace is running under load, the telescopic drive is controlled by a corresponding controller to cause the cone-tip connection positioning shaft to extend and cooperate with the corresponding conical connecting sleeve to position and strengthen the cantilever.

[0016] The belt-spinning roller, its adaptive automatic balancing circulation cooling system, and its polishing device are all installed on the sliding frame. A track device is provided between the sliding frame and the machine frame.

[0017] The belt-spinning roller 20 is fixedly connected to a hollow shaft 19 corresponding to the nozzle at the lower end of the medium-frequency induction heating furnace. The hollow shaft is mounted on a slide 50 via a hollow shaft mounting bearing 46. The medium-frequency induction heating furnace and the nozzle are mounted on a cantilever of the frame. The slide 50 is mounted on the frame 40 via a track assembly 51. A piston cylinder or servo-driven electric telescopic rod is connected between the slide 50 and the frame 40. The slide 50, via its track assembly 51, can move back and forth along the axial direction of the belt-spinning roller relative to the nozzle on the medium-frequency induction heating furnace.

[0018] Control by corresponding controller, when working, get rid of belt roller 20 by its slide frame and track arrangement thereof, can with respect to nozzle along get rid of belt roller axial direction, with certain speed, frequency continuous or intermittent movement back and forth, can with get rid of belt roller surface different positions and nozzle correspondingly carry out rotation and get rid of band.That is, when running, get rid of belt roller with certain frequency, speed continuous or intermittent change its rotation and get rid of working position.It can avoid getting rid of belt roller all the time or long period operation in same position and accept nozzle spray and spin and get rid of, both effectively protected getting rid of belt roller operation local overheating and destruction, damage get rid of belt roller, and can avoid getting rid of belt roller because of local excessive long-time operation and influence its surface finish, and then influence spray band quality.

[0019] In Example 2 of the present invention. Figure 2-3 As shown in the figure, the dynamic sealing connection device 22 includes, among other things, a connecting sleeve 10 fixedly connected to the slide frame. A stationary ring 11 is positioned within the inner cavity of the connecting sleeve, with a seal 13 positioned between the outer circumference of the stationary ring and the inner circumference of the connecting sleeve. One end of the hollow shaft 19 is rotatably connected to the connecting sleeve 10 via a corresponding bearing 15. A shaft retaining ring 14 and a hole retaining ring 16 are respectively connected between the hollow shaft and the connecting sleeve on either side of the bearing 15. Wear-resistant alloy or ceramic rings 12 are embedded in the facing end faces of the stationary ring and the hollow shaft, respectively. The stationary ring and the hollow shaft are frictionally sealed together by their wear-resistant alloy or ceramic rings.

[0020] The corresponding end surface of the connecting sleeve 10 is evenly distributed around its axis with multiple accommodating holes. The piston rod of the piston cylinder 17 is connected to the corresponding side wall of the stationary ring 11 through a balance frame 18 composed of multiple connecting rods. The piston cylinder body is fixedly connected to the corresponding part of the connecting sleeve or the sliding frame.

[0021] The two drive medium connections of the piston cylinder are connected to corresponding ports of a two-position, four-way control solenoid valve 30. The other two ports of the two-position, four-way control solenoid valve 30 are connected to the cooling water input 19a and output 19b of the belt-spinning roller. The electrical signals of the two-position, four-way control solenoid valve 30 are connected to the corresponding controller 31. The water inlet and outlet of the connecting sleeve 10 are connected to corresponding elastic pipe connectors (rubber pipe connectors) 28. These rubber pipe connectors are also connected to the cooling water output and input of the belt-spinning roller.

[0022] During operation, cooling water flows from the cooling water source through the water inlet at one end of the hollow shaft into the cooling cavity on one side of the guide inner cylinder of the belt-spinning roller, and then flows back to the cooling water source through the cooling cavity and water outlet on the other side of the guide inner cylinder. Based on the pressure difference between the input and output of the cooling water of the belt-spinning roller, the piston cylinder applies a certain pressure to the stationary ring through its piston rod, achieving a dynamic and static friction seal connection of the cooling water flow channel.

[0023] The piston cylinder balances the pressure applied to the stationary ring, balancing the sealing friction between the stationary ring and the end face of the hollow shaft. This balances the dynamic and static seals with minimal pressure. Furthermore, because the piston cylinder is connected to the cooling water input and output channels of the belt-spinning roller, utilizing the pressure differential of its own circulating cooling water for differential drive control, the sealing friction is adaptively adjusted, resulting in excellent dynamic and static friction sealing performance and significant savings in power consumption.

[0024] The connecting end of the cantilever can also be rotatably connected to the corresponding end column of the frame, which makes it easy to rotate the cantilever to make way for the installation, debugging and maintenance of the equipment below it. The remaining structures and operation control methods of this example are similar to those of the above embodiment.

[0025] In Example 3 of the present invention. Figure 4 As shown. Its controller is provided with a given module 31a, and the cooling water channel of the cooling inner cavity of the belt-spinning roller is provided with a differential pressure sensor 32. The electrical signal of the differential pressure sensor is connected to the controller 31, and the electrical signal of the corresponding output end of the controller is connected to the control electromagnetic valve 30a of the piston cylinder. The other two ports of the control electromagnetic valve 30a are respectively connected to the corresponding driving medium pressure source 19c and the medium return source 19d of the piston cylinder. An initial pressure value is set by the given device of the controller, and the controller superimposes the initial pressure value with the pressure detection signal input by the differential pressure sensor, and then outputs a control signal according to the superimposed signal to control the piston cylinder to apply a certain pressure to the stationary ring. The given value of its given device is generally greater than or equal to zero. The rest of the structure and operation control method of this example can be similar to the above-mentioned embodiment.

[0026] In embodiment 4 of the present invention, the cooling water input and output ends of the cooling inner cavity of the belt-spinning roller are directly or through corresponding control valves connected to the two driving medium ports of the piston cylinder. The remaining structure and operation control method of this embodiment are similar to those of the above embodiment.
