Description

Technical Field

[0001] The invention relates to the field of electric heating tube shell polishing, in particular to a heater electric heating tube shell polishing device. Background Art

[0002] An electric heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, high in heating power, widely used, uses an intelligent control mode, has high temperature control accuracy, and can be connected to a computer network. It has a wide range of applications, long life, and high reliability. The core of the heater principle is energy conversion. The most common is the conversion of electrical energy into thermal energy, using electrical energy as a heat source, including electric heating tubes, electric heating wires, electric heating plates, etc. They are widely used in heating homes, offices, and industrial equipment, and the heating tube is the most important component of the heater.

[0003] A heating tube is an electrical component that converts electrical energy into thermal energy. It has a metal tube as its outer shell, and the metal shell needs to be polished before use, because polishing can remove the tiny unevenness and burrs on the surface of the heating tube shell, reduce the hiding places of corrosive media, and improve corrosion resistance. The surface of the heating tube shell after polishing is smoother, not easy to be contaminated with dirt, and easy to clean and maintain. By polishing to remove the oxide layer and other impurities on the surface, the heat conduction efficiency of the heating tube can be improved, making it heat more evenly and quickly. The smooth surface helps to reduce heat loss through the shell and improve heating efficiency. The surface of the heating tube shell after polishing is more uniform, which helps the uniform adhesion of coatings or other surface treatment processes and enhances protective performance. A polishing device is usually used to polish the heating tube shell.

[0004] The polishing device usually includes a driving motor, a polishing roller and an auxiliary roller, which bring the outer shell of the heating tube into contact with the polishing roller and the auxiliary roller, and polish the surface of the outer shell of the heating tube by rotating the polishing roller and the auxiliary roller. The polished heater shell can be rotated and moved by cooperating with the polishing roller and the auxiliary roller, so as to fully polish the outer shell of the heating tube.

[0005] However, when the heater shell is polished by the polishing device, the radius and wall thickness of the heater shell are different due to the different models of the heater. Therefore, when replacing the heater shell with different radius and wall thickness, the heater shell is placed between the polishing roller and the auxiliary roller, and the distance between the polishing tube and the auxiliary roller is adjusted. The rotation speed and the applied pressure are adjusted according to the radius and wall thickness of the heater shell. When the production line needs to frequently change the specifications of the electric heating tube, the above method takes a lot of time. If the rotation speed and pressure are not properly controlled during the adjustment process, the heater shell will not be fully polished, or it will be bent and damaged, and the polishing quality will be inconsistent. Based on the above problems, the present application proposes a heater electric heating tube shell polishing device. Summary of the invention

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a heater electric heating tube shell polishing device.

[0034] Embodiment 1:

A shell detection component 25 is arranged on the top of the loading bin 22. A positioning guide component 26 is arranged inside the loading bin 22. The heating tube shell of the heater is put in from the left side of the loading bin 22. The output end of the electric push rod 23 is driven to push the loading push plate 24 to move to the right, push the heating tube shell to move to the right, and position the heating tube shell in the middle position of the loading bin 22 through the shell positioning guide component 26. Then, the radius and wall thickness of the heating tube shell of the heater are detected through the shell detection component 25, so as to facilitate the adjustment of the polishing device according to the detected radius and wall thickness.

[0038] The shell polishing component 3 is arranged on the top of the mounting base 1 and is used for polishing the electric heating tube shell of the heater. The shell polishing component 3 includes a gantry mounting frame 31 fixedly mounted on the top of the mounting base 1.

A polishing piece 34 is arranged on the top of the I-shaped slider 33. An adjusting piece 35 is arranged inside the gantry mounting frame 31. The adjusting piece 35 is mounted on the top of the mounting base 1. According to the radius and wall thickness detected by the shell detection piece 25, the adjusting piece 35 adjusts the distance between the two I-shaped sliders 33, thereby adaptively adjusting the polishing piece 34, so that the polishing piece 34 can polish shells with different radii and different wall thicknesses, and the polishing speed and polishing pressure of the polishing piece 34 can be adaptively adjusted according to the detected radius and wall thickness, thereby avoiding the problem of too fast or too slow polishing speed, and avoiding the problem of too small or too large polishing pressure.

[0039] As a preferred implementation in this embodiment, refer to Figure 4 and Figure 5As shown, the housing detection member 25 includes a U-shaped plate 251 fixedly mounted on the top of the mounting base 1, a moving rod 252 is slidably arranged inside the U-shaped plate 251, a housing radius measuring plate 253 is fixedly arranged at the bottom end of the moving rod 252, the housing radius measuring plate 253 is a frame structure, the left side of the housing radius measuring plate 253 is an arc surface, the housing radius measuring plate 253 is made of metal material, the metal frame structure can reduce the weight and cost of the housing radius measuring plate 253, and the arc surface facilitates the housing to push the housing radius measuring plate 253 to move, a connecting plate 254 is fixedly arranged on the right side of the housing radius measuring plate 253, an ultrasonic wall thickness detection sensor 255 is fixedly arranged inside the connecting plate 254, and the top of the moving rod 252 is fixedly mounted. A telescopic spring 256 is fixedly provided, and a fixed plate 257 is fixedly provided at the top of the telescopic spring 256. The fixed plate 257 is fixedly installed on the rear side of the U-shaped plate 251. A sliding resistor 258 is fixedly provided on the rear side wall of the fixed plate 257. The moving rod 252 is connected to the sliding piece of the sliding resistor 258. The positioning guide 26 includes a fixed pin 261 threadedly provided inside the upper bin 22. A flip plate 262 is rotatably provided on the surface of the fixed pin 261. A connecting spring 263 is connected between the side of the flip plate 262 and the inner wall of the upper bin 22. The flip plate 262 is tilted, and both sides of the flip plate 262 are semicircular. The flip plate 262 is made of metal material, and the connecting spring 263 is an arc spring. The tilted flip plate 262 , which is convenient for the heating tube shell to push the flip plate 262 to flip, avoiding the heating tube shell being blocked by the flip plate 262 and unable to move, and the two semicircular sides prevent the flip plate 262 from scratching the surface of the heating tube shell, avoiding the scratching of the surface of the heating tube shell and affecting the polishing effect. The surface of the upper bin 22 is penetrated with a mounting groove for installing the flip plate 262. The heating tube shell pushes the flip plate 262 to compress the connecting spring 263, and the flip plates 262 on the front and rear sides push the heating tube shell to the middle position of the upper bin 22. Then the heating tube shell pushes the shell radius measuring plate 253 to move upward, so that the connecting plate 254 drives the ultrasonic wall thickness detection sensor 255 to move upward, and at the same time, the moving rod 2 52 compresses the telescopic spring 256. At this time, the moving rod 252 drives the slider of the slider resistor 258 to move upward. Since the larger the radius of the heating tube shell, the higher the slider moves, and the larger the resistance of the slider resistor 258, the radius of the heating tube shell is obtained by changing the resistance of the slider resistor 258. When the resistance of the slider resistor 258 no longer changes and the heating tube shell moves to the bottom of the ultrasonic wall thickness detection sensor 255 and contacts with its bottom, the wall thickness of the heating tube shell is detected by the ultrasonic wall thickness detection sensor 255, so that the radius and wall thickness of the heating tube shell can be measured at the same time, thereby facilitating the adaptive adjustment of the shell polishing component 3, and there is no need to adjust the shell polishing component 3 in multiple steps.

[0040] It is worth mentioning that the ultrasonic wall thickness detection sensor 255 mentioned above is mainly composed of a piezoelectric chip, a transmitting head and a receiving head. It transmits and receives ultrasonic pulse waves and measures the propagation time of sound waves in the material, thereby calculating the thickness of the material. The slider resistor 258 is mainly composed of a terminal, a slider, a coil, a metal rod and a porcelain tube. The position of the slider cannot be moved, and the resistance value of the slider resistor 258 is different. Therefore, the ultrasonic wall thickness detection sensor 255 and the slider resistor 258 are existing mature technical structures, so the present invention will not be described in detail.

The vertical screw sleeve 353 drives the end of the vertical flip rod 354 close to it to move upward or downward through the hinge seat, and the vertical flip rod 354 is also One end pushes the two I-shaped sliders 33 away from or towards each other through the hinge seat, and the two I-shaped sliders 33 simultaneously drive the installation shaft 1 343 and the installation shaft 2 347 to move through the installation frame 341 and the connecting frame 345, so that the polishing roller 344 and the auxiliary roller 348 move away from or towards each other, and at the same time, the active bevel gear 355 drives the driven bevel gear 356 meshing with it to rotate, so that the transverse screw 357 rotates inside the support plate 358 through the bearing, and the transverse screw sleeve 359 drives the bottom end of the transverse flip rod 3510 to move to the right or left through the hinge seat, so that the transverse flip rod 3510 drives the connecting column 3511 to move downward or upward through the hinge seat, and drives the upper bin 22 to move downward or upward through the connecting column 3511.The center of the heating tube shell is in the same horizontal plane as the center of the polishing roller 344 and the auxiliary roller 348, and the pressure of the polishing roller 344 and the auxiliary roller 348 on the heating tube shell is controlled according to the detected wall thickness, and the speed of the polishing roller 344 is controlled, so as to facilitate adaptive adjustment of the distance between the polishing roller 344 and the auxiliary roller 348, the pressure applied by the polishing roller 344 and the auxiliary roller 348 on the heating tube shell, and the polishing speed of the polishing roller 344.

Therefore, the displacement sensor 3513 is an existing mature technical structure, and therefore the present invention will not be described in detail.

[0043] Embodiment 2:

[0044] Please refer to Fig. 9 and Fig.10 The difference between this embodiment and the above-mentioned embodiment is that an inverted U-shaped mounting plate 4 is fixedly arranged on the top of the gantry mounting frame 31, a collecting box 5 and an air suction fan 6 are fixedly arranged on the top of the inverted U-shaped mounting plate 4, an air inlet end of the air suction fan 6 is connected to the front side of the collecting box 5, a dust inlet pipe 7 is fixedly arranged on the top of the collecting box 5, an air outlet end of the dust inlet pipe 7 passes through the inverted U-shaped mounting plate 4 and extends to the inside of the inverted U-shaped mounting plate 4, a storage box 8 is slidably arranged inside the collecting box 5, the rear side of the storage box 8 is connected to the collecting box 5 by bolts, and a filter screen 9 is fixedly arranged on the front side of the storage box 8. When the outer shell of the heating tube of the heater is polished , start the suction fan 6, so that the dust inlet pipe 7 sucks the dust and waste generated by polishing into the collection box 5, and enters the storage box 8 inside the collection box 5, and under the influence of the dust suction fan, the dust and waste entering move to the front side of the storage box 8, and then the dust and waste are blocked by the filter 9, so that the dust and waste fall into the storage box 8. When the dust and waste collected in the storage box 8 are too much, the storage box 8 is taken out of the collection box 5, so that the storage box 8 drives the filter 9 to move out of the collection box 5, the dust and waste collected in the storage box 8 are poured out, and the surface of the filter 9 is cleaned.

[0045] The working principle of the present invention is as follows: when in use, the heating tube shell of the heater is put in from the left side of the upper bin 22, and the output end is driven by the electric push rod 23 to push the loading push plate 24 to move to the right, push the heating tube shell to move to the right, and push the flip plate 262 to flip with the fixed pin 261 as the center, and compress the connecting spring 263, and push the heating tube shell to the middle position of the upper bin 22 through the flip plates 262 on the front and rear sides;

[0046] The outer shell of the heating tube continues to move to the right, and pushes the outer shell radius measuring plate 253 to move upward. The outer shell radius measuring plate 253 drives the ultrasonic wall thickness detection sensor 255 to move upward through the connecting plate 254. At the same time, the outer shell radius measuring plate 253 pushes the moving rod 252 to compress the telescopic spring 256. At this time, the moving rod 252 drives the slider of the slider resistor 258 to move upward, so that the resistance of the slider resistor 258 increases. When the outer shell of the heating tube contacts the bottom of the outer shell radius measuring plate 253, the resistance of the slider resistor 258 no longer changes. When the outer shell of the heating tube moves to the bottom of the ultrasonic wall thickness detection sensor 255 and contacts the bottom thereof, the wall thickness of the outer shell of the heating tube is detected by the ultrasonic wall thickness detection sensor 255.

[0047] Then, the servo motor 351 drives the output end to drive the vertical screw 352 and the active bevel gear 355 to rotate. When it is detected that the radius and wall thickness of the heater shell are increased relative to the previous one, the vertical screw sleeve 353 moves upward, and the vertical screw sleeve 353 drives the end of the vertical flip rod 354 close to it to move upward through the hinge seat. The other end of the vertical flip rod 354 pushes the two I-shaped sliders 33 away from each other through the hinge seat, and the two I-shaped sliders 33 simultaneously drive the installation shaft 1 343 and the installation shaft 2 347 to move through the installation frame 341 and the connecting frame 345, so that the polishing roller 344 and the auxiliary roller 348 are away from each other. At the same time, the active bevel gear 355 drives the driven bevel gear meshed with it. The gear 356 rotates, so that the transverse screw rod 357 rotates inside the support plate 358 through the bearing, and the transverse screw sleeve 359 drives the bottom end of the transverse flip rod 3510 to move to the right through the hinge seat, so that the transverse flip rod 3510 drives the connecting column 3511 to move downward through the hinge seat, and drives the upper bin 22 to move downward through the connecting column 3511, and the moving direction of the upper bin 22 is limited and guided by the telescopic rod 21, so that the center of the heating tube shell and the centers of the polishing roller 344 and the auxiliary roller 348 are in the same transverse horizontal plane, and according to the detected wall thickness, the pressure of the polishing roller 344 and the auxiliary roller 348 on the heating tube shell is controlled, and the rotation speed of the polishing roller 344 is controlled;

[0048] When it is detected that the heater shell is reduced in radius and wall thickness relative to the previous one, the vertical screw sleeve 353 drives the end of the vertical flip rod 354 close to it to move downward through the hinge seat, and the other end of the vertical flip rod 354 drives the two I-shaped sliders 33 to approach each other through the hinge seat, so that the polishing roller 344 and the auxiliary roller 348 are close to each other, and at the same time, the active bevel gear 355 drives the transverse screw 357 to rotate through the driven bevel gear 356, and the transverse screw sleeve 359 drives the bottom end of the transverse flip rod 3510 to move to the left through the hinge seat, so that the transverse flip rod 3510 drives the connecting column 3511 to move upward through the hinge seat, and drives the upper bin 22 to move upward through the connecting column 3511, and according to the detected wall thickness, the pressure of the polishing roller 344 and the auxiliary roller 348 on the heater shell is controlled, and the rotation speed of the polishing roller 344 is controlled;

[0049] Subsequently, the output end of the driving motor 1 342 drives the polishing roller 344 to rotate through the mounting shaft 1 343, and at the same time, the output end of the driving motor 2 346 drives the auxiliary roller 348 to rotate through the mounting shaft 2 347, wherein the rotation speed of the auxiliary roller 348 is less than the rotation speed of the polishing roller 344, so that a speed difference is formed between the polishing roller 344 and the auxiliary roller 348, and the incoming heating tube shell is polished with the cooperation of the polishing roller 344 and the auxiliary roller 348, and the polishing roller 344 and the auxiliary roller 348 will drive the polished heating tube shell to move and rotate at the same time. When the polishing of one heating tube shell is completed, the next heating tube shell of the same specification enters the polishing process, and when the radius and wall thickness of the next heating tube shell change, it will be adaptively adjusted again.
