Description

Technical Field

[0001] The present invention relates to the field of electric heating tube processing equipment, and particularly to a processing device for electric heating tubes of solar water heaters. Background Art

[0002] With the increasing global demand for clean energy, solar water heaters, as a hot water supply device that efficiently utilizes solar energy, have been widely applied and popularized in the market. In recent years, the solar water heater industry has developed rapidly, and the production scale has been continuously expanding, which has put forward higher requirements for the processing quality and efficiency of electric heating tubes, the key components of solar water heaters. In the traditional processing of electric heating tubes for solar water heaters, many technical problems are faced. In terms of the cutting link, most of the early cutting equipment adopted relatively simple manual or semi-automatic cutting methods. Manual cutting highly depends on the experience and skill level of operators. Not only is the cutting efficiency low, making it difficult to meet the needs of large-scale production, but also the accuracy of the cutting size is difficult to guarantee, and problems such as uneven cuts, excessive burrs and flash are likely to occur at the cut. These defects will increase the difficulty of subsequent processing procedures and even affect the overall performance and service life of the electric heating tube. Although semi-automatic cutting equipment has improved the cutting efficiency to a certain extent, during the cutting process, the resistance between the cutting tool and the electric heating tube is large, and the cutting tool wears severely. Frequent replacement of the cutting tool not only increases the production cost but also further reduces the production efficiency. In terms of the polishing process, traditional polishing methods often use manual polishing tools to polish the outer wall of the electric heating tube. This method has a high labor intensity, a harsh working environment, and the polishing effect varies from person to person, making it difficult to achieve a uniform and consistent polishing quality. Even if some simple mechanical polishing equipment is used, due to its unreasonable structural design, it cannot be flexibly adjusted according to the different pipe diameters and materials of the electric heating tubes, resulting in poor polishing effects and unable to meet the increasingly high requirements for product appearance quality. In addition, during the traditional processing of electric heating tubes, each process such as cutting and polishing is usually carried out independently, lacking an effective collaborative operation mechanism. This makes the entire processing flow cumbersome and the material handling frequent, not only increasing the production cycle but also easily causing damage to the electric heating tubes during the handling process, further affecting the product quality. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment

[0018] Please refer to the attached Figure 1 - attached Figure 6 , the embodiment of the present invention provides a processing device for an electric heating tube of a solar water heater, such as Figure 1As shown in the figure, it includes a workbench 1. The workbench 1 serves as the basic support structure of the entire device, providing a stable platform for the installation and operation of other components. On one side of the rear end of the workbench 1, a first backboard 2 is fixedly installed. The first backboard 2 plays a key role in supporting and positioning a series of transmission and moving components. On one side of the front end of the first backboard 2, a first movable block 3 is movably installed through a guide rail. The guide rail provides guidance for the movement of the first movable block 3, enabling it to move stably along a specific direction. Below the first movable block 3, a second movable block 4 is provided. The two work together to achieve a specific action combination. Inside the second movable block 4, a rotating shaft 5 is movably installed. The rotating shaft 5 is a key component for power transmission and driving the saw blade cutter 6 to work. One end extends to the outside of one side of the second movable block 4 and is fixedly installed with the saw blade cutter 6. The saw blade cutter 6 is responsible for cutting the electric heating tube in subsequent work. On the other side of the front end of the first backboard 2, a first motor 21 is fixedly installed. The first motor 21 serves as the cutting power source, and its driving end is fixedly installed with a main shaft 22. The main shaft 22 transmits the rotational power of the first motor 21. The end of the main shaft 22 is installed with a coupling shaft 26 through a universal joint. The coupling shaft 26 is then installed at the other end of the rotating shaft 5 through a universal joint. The setting of the universal joint ensures stable power transmission even in the presence of an angular deviation during the power transmission process, enabling the rotation of the main shaft 22 to reliably drive the rotating shaft 5 and the saw blade cutter 6 to rotate at high speed. On the other side of the rear end of the workbench 1, a second backboard 27 is fixedly installed. The second backboard 27 is also used to support and position related components. On one side of the front end of the second backboard 2, two movable shafts 28 are movably installed. At the ends of the movable shafts 28, conveying wheels 29 are fixedly installed. The two conveying wheels 29 cooperate to clamp and convey the solar electric heating tube to be processed. In the middle of the upper surface of the workbench 1, a fixed ring 41 is fixedly installed through a bracket. The fixed ring 41 plays a role in initially positioning the position of the electric heating tube. An activity ring 42 is movably installed on the inner ring of the fixed ring 41. The activity ring 42 can rotate flexibly within the fixed ring 41. On the upper and lower sides of the inner wall of the activity ring 42, polishing plates 44 are installed through spring rods 43. The spring rods 43 use their elasticity to make the polishing plates 44 closely fit the outer wall of the electric heating tube. When the activity ring 42 rotates, the polishing plates 44 polish and grind the outer wall of the electric heating tube. On the upper surface of the workbench 1, near the position below the second movable block 4, a support frame 46 is fixedly installed. The support frame 46 is used to support the electric heating tube to be cut, ensuring the stability of the electric heating tube during the cutting process.

[0019] In this embodiment, both ends of the top of the second movable block 4 are connected to the bottom of the first movable block 3 through return springs 7. The return springs 7 provide a restoring force for the up-and-down movement of the second movable block 4. A first driving bevel gear 8 is fixedly installed on the outer diameter of the middle part of the rotating shaft 5. The first driving bevel gear 8 transmits power when the rotating shaft 5 rotates. A short shaft 9 is movably installed on the upper side inside the second movable block 4. The short shaft 9 is responsible for transmitting power. A first driven bevel gear 10 is fixedly installed at the bottom end of the short shaft 9, and the first driven bevel gear 10 is meshed and connected to the inner side end of the short shaft 9. Through this meshing relationship, the rotation of the first driving bevel gear 8 drives the rotation of the short shaft 9. The top end of the short shaft 9 extends to the outside of the second movable block 4 and is fixedly installed with a lower clamping plate 11. The middle part of the bottom end of the first movable block 3 is fixedly installed with an upper clamping plate 12. The lower clamping plate 11 and the upper clamping plate 12 cooperate with each other. A plurality of hemispherical protrusions 13 are fixedly installed at the inner side ends of the lower clamping plate 11 and the upper clamping plate 12, and the installation positions of the hemispherical protrusions 13 on both sides are staggered. This staggered hemispherical protrusion 13 structure forms a special tooth-engaging structure with the upper clamping plate 12 when the short shaft 9 drives the lower clamping plate 11 to rotate, generating a unique vibration effect.

[0020] Specifically, when the rotating shaft 5 rotates, it will also drive the rotation of the first driving bevel gear 8. The first driving bevel gear 8 will drive the short shaft 9 and the first driven bevel gear 10 to rotate, thereby driving the rotation of the lower clamping plate 11. When the lower clamping plate 11 rotates, it will utilize the tooth-engaging structure formed by the hemispherical protrusions 13 that are mutually misaligned with the upper clamping plate 12, and cooperate with the return spring 7 to drive the second movable block 4 to vibrate quickly up and down, so that the high-speed rotating saw blade cutter 6 follows the up-and-down vibration. This not only reduces the overall resistance during cutting, reduces the tool load, but also can polish the cut, reduce the generation of burrs and flash, and improve the product output quality.

[0021] Furthermore, a cylindrical groove 14 is provided in the middle of the top end of the first movable block 3. The cylindrical groove 14 provides an installation and movement space for the rotating column 15. The rotating column 15 is movably arranged inside the cylindrical groove 14. The rotating column 15 plays a key role in subsequent power transmission and controlling the movement of the first movable block 3. A bidirectional spiral groove 16 is provided on the outer diameter of the rotating column 15. A round head pin 17 is fixedly installed on one side of the inner top of the cylindrical groove 14, and the end of the round head pin 17 is movably arranged inside the bidirectional spiral groove 16. The round head pin 17 slides in the bidirectional spiral groove 16, converting the rotational movement of the rotating column 15 into a linear reciprocating movement of the first movable block 3.

[0022] Further, a transmission shaft 18 is movably installed on the upper side of the front end of the first back plate 2 through a bearing mounting seat. The transmission shaft 18 is used to transmit power. A second driving bevel gear 19 is fixedly installed at one end thereof close to the first movable block 3. The top end of the rotating column 15 is fixedly installed with a second driven bevel gear 20, and the second driven bevel gear 20 is meshed and connected to the inner end of the second driving bevel gear 19. Through the meshing of such bevel gears, the rotation of the transmission shaft 18 drives the rotation of the rotating column 15.

[0023] Further, a first driving wheel 23 is fixedly installed on the outer diameter of the middle part of the main shaft 22, and a first driven wheel 24 is fixedly installed on the outer diameter of one side of the transmission shaft 18 away from the first movable block 3. The outside of the first driving wheel 23 and the first driven wheel 24 are connected by a first transmission belt 25. By using the transmission function of the first transmission belt 25, the rotational power of the main shaft 22 is transmitted to the transmission shaft 18.

[0024] Specifically, start the first motor 21. Drive the main shaft 22 to rotate through the first motor 21. Drive the coupling shaft 26 and the rotating shaft 5 to rotate by using the transmission of the universal joint. The rotating shaft 5 drives the saw blade cutter 6 to rotate at a high speed. At the same time, when the main shaft 22 rotates, it will drive the first driving wheel 23 to rotate. Drive the first driven wheel 24 and the transmission shaft 18 to rotate by using the transmission of the first transmission belt 25. When the transmission shaft 18 rotates, it will drive the second driving bevel gear 19 at the end to rotate. The second driving bevel gear 19 drives the second driven bevel gear 20 and the rotating column 15 to rotate. The selected rotating column 15 drives the bidirectional spiral groove 16 on the surface to rotate and makes the round head pin 17 slide inside it. By using the limiting effect of the guide rail on the first movable block 3, the first movable block 3 makes a linear motion along the direction of the guide rail. Since the bidirectional spiral groove 16 is composed of two spiral grooves with opposite spiral directions but connected end to end, when the round head pin 17 moves to the end of one spiral groove, it will enter the beginning of the other spiral groove and change the direction of motion. Therefore, as the rotating column 15 rotates continuously, it drives the first movable block 3 to make a reciprocating up and down motion. The first movable block 3 drives the second movable block 4 to move accordingly, thereby driving the saw blade cutter 6 to move up and down. When the saw blade cutter 6 descends, the cutting work of the electric heating tube is completed. When the saw blade cutter 6 ascends, the electric heating tube continues to move forward to facilitate the next cutting. This process is repeated continuously to complete the continuous cutting work of the electric heating tube.

[0025] Further, a second motor 30 is fixedly installed on the upper side of the front end of the second back plate 27. The second motor 30 serves as the power source for the conveying and polishing parts. A second driving wheel 31 is fixedly installed at the driving end of the second motor 30. A second driven wheel 32 is fixedly installed on the outer diameter of the front side of the upper movable shaft 28. The outer diameters of the second driving wheel 31 and the second driven wheel 32 are connected by a second transmission belt 33. Through the transmission of the second transmission belt 33, the power of the second motor 30 drives the upper movable shaft 28 and the conveying wheel 29 to rotate, realizing the conveyance of the electric heating tube. The rear end of the lower movable shaft 28 is movably installed at one end of a slider 39. The bottom end of the slider 39 is connected to the upper surface of the workbench 1 through a jacking spring 40. The jacking spring 40 jacks up the slider 39, the lower movable shaft 28 and the lower conveying wheel 29 upward, so that the two conveying wheels 29 can tightly clamp the electric heating tube.

[0026] Further, a rotating rod 34 is movably installed on the other side of the front end of the second back plate 27. A third driving wheel 35 is fixedly installed on the outer diameter of the rear side of the upper movable shaft 28. A third driven wheel 36 is fixedly installed on the outer diameter of the middle part of the rotating rod 34. The outer diameters of the third driving wheel 35 and the third driven wheel 36 are connected by a third transmission belt 37. The rotation of the upper movable shaft 28 drives the rotating rod 34 to rotate through the transmission of the third transmission belt 37. A third driving bevel gear 38 is fixedly installed at the end of the rotating rod 34. A third driven bevel gear 45 is fixedly installed on the outer diameter of one side of the movable ring 42, and the third driven bevel gear 45 is meshed and connected to the inner end of the third driving bevel gear 38. Through the meshing of this pair of bevel gears, the rotation of the rotating rod 34 drives the movable ring 42 and the internal spring rod 43 and polishing plate 44 to rotate at high speed, polishing the outer wall of the electric heating tube.

[0027] Specifically, the second motor 30 is driven to rotate the second driving wheel 31. By using the transmission of the second transmission belt 33, it drives the second driven wheel 32 and the upper movable shaft 28 to rotate, thereby driving the upper conveying wheel 29 to rotate to convey the electric heating tube. At the same time, when the upper movable shaft 28 rotates, it will drive the third driving wheel 35 to rotate. Through the transmission of the third transmission belt 37, it drives the third driven wheel 36 and the rotating rod 34 to rotate, thereby driving the third driving bevel gear 38 at the end of the rotating rod 34 to rotate. The rotating third driving bevel gear 38 will drive the third driven bevel gear 45 and the movable ring 42 to rotate, thereby driving the spring rod 43 and the polishing plate 44 inside the movable ring 42 to rotate at high speed. The polishing plate 44 adheres to the outer wall of the electric heating pipe through the spring rod 43 and polishes the outer wall of the pipe during high-speed rotation.

[0028] Working principle: The solar electric heating tubes to be processed are sequentially passed through between two conveying wheels 29 and inside the fixing ring 41 and placed above the support frame 46. The lifting spring 40 will push up the slider 39, the lower movable shaft 28 and the lower conveying wheel 29, so that the two conveying wheels 29 clamp the electric heating tube. Then, the second motor 30 is started, and the second driving wheel 31 is driven to rotate by the second motor 30. Through the transmission of the second transmission belt 33, the second driven wheel 32 and the upper movable shaft 28 are driven to rotate, so as to drive the upper conveying wheel 29 to rotate and convey the electric heating tube. At the same time, when the upper movable shaft 28 rotates, it will drive the third driving wheel 35 to rotate. Through the transmission of the third transmission belt 37, the third driven wheel 36 and the rotating rod 34 are driven to rotate, so as to drive the third driving bevel gear 38 at the end of the rotating rod 34 to rotate. The rotating third driving bevel gear 38 will drive the third driven bevel gear 45 and the movable ring 42 to rotate, so as to drive the spring rod 43 and the polishing plate 44 inside the movable ring 42 to rotate at high speed. The polishing plate 44 adheres to the outer wall of the electric heating pipe through the spring rod 43 and polishes and grinds the outer wall of the pipe at high speed. The polished electric heating tube is conveyed to the lower part of the second movable block 4. When the electric heating tube extends a certain length out of the support frame 46, the second motor 30 stops rotating. At this time, the first motor 21 is started, and the main shaft 22 is driven to rotate by the first motor 21. Through the transmission of the universal joint, the connecting shaft 26 and the rotating shaft 5 are driven to rotate. The rotating shaft 5 drives the saw blade cutter 6 to rotate at high speed. At the same time, when the main shaft 22 rotates, it will drive the first driving wheel 23 to rotate. Through the transmission of the first transmission belt 25, the first driven wheel 24 and the transmission shaft 18 are driven to rotate. When the transmission shaft 18 rotates, it will drive the second driving bevel gear 19 at the end to rotate. The second driving bevel gear 19 drives the second driven bevel gear 20 and the rotating column 15 to rotate. The selected rotating column 15 drives the bidirectional spiral groove 16 on the surface to rotate and makes the round head pin 17 slide inside it. By using the limiting effect of the guide rail on the first movable block 3, the first movable block 3 moves linearly along the direction of the guide rail. Since the bidirectional spiral groove 16 is composed of two spiral grooves with opposite spiral directions but connected end to end, when the round head pin 17 moves to the end of one spiral groove, it will enter the beginning of the other spiral groove and change the movement direction. Therefore, as the rotating column 15 rotates continuously, the first movable block 3 moves up and down reciprocally. The first movable block 3 drives the second movable block 4 to move accordingly, so as to drive the saw blade cutter 6 to move up and down. When the saw blade cutter 6 descends, the cutting work of the electric heating tube is completed. When the saw blade cutter 6 ascends, the electric heating tube continues to move forward, facilitating the next cutting. This cycle is repeated to complete the continuous cutting work of the electric heating tube. In addition, when the rotating shaft 5 rotates, it will also drive the first driving bevel gear 8 to rotate. The first driving bevel gear 8 drives the short shaft 9 and the first driven bevel gear 10 to rotate, so as to drive the lower clamping plate 11 to rotate. When the lower clamping plate 11 rotates, it will use the toothed structure formed by the hemispherical protrusions 13 that are mutually misaligned with the upper clamping plate 12, and cooperate with the return spring 7 to drive the second movable block 4 to vibrate quickly up and down.The high-speed rotating saw blade cutter 6 follows the up-and-down vibration, which not only reduces the overall resistance during cutting, decreases the tool load, but also can polish the cut, reduce the generation of burrs and flash, and improve the output quality of the product.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
