Description

Technical Field

[0001] This invention relates to the field of pipe grinding equipment technology, specifically to an anti-corrosion composite pipe and its grinding equipment. Background Technology

[0002] Corrosion-resistant composite pipes are composed of two or more different materials. Their core purpose is to resist corrosion and extend the pipe's service life. After production, the outer surface of the composite pipe is relatively rough. To meet the needs of certain special applications, the outer surface needs to be polished to make it smooth. This is done by clamping the pipe with two fixed seats and driving it to rotate. Then, a reciprocating sanding belt polishes the rotating outer surface of the composite pipe. During polishing, a lot of dust is generated on the pipe. Therefore, a vacuum pipe needs to be fixedly installed under the moving sanding belt for thorough dust removal. To prevent dust pollution, the dust that overflows during sanding with the rapidly rotating pipe and sanding belt has a large inertia and may escape, resulting in poor dust collection. To further reduce dust escape and promote dust absorption by the suction pipe, dust covers need to be installed on both sides of the sanding belt. The dust covers can block and intercept the escaped dust as much as possible, reducing its escape. The dust that is intercepted and adheres to the inner wall of the dust cover falls down the inner wall of the dust cover and is absorbed by the suction pipe. However, some dust accumulates on the inner wall of the dust cover and is difficult to fall down. When it accumulates to a certain thickness, it affects the dust-blocking function of the dust cover. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides a corrosion-resistant composite pipe and its grinding equipment, employing the following technical solution:

[0004] The device includes a base, on which a first fixing mechanism and a second fixing mechanism are fixedly connected. A corrosion-resistant composite pipe is fixedly connected between the first fixing mechanism and the second fixing mechanism. A drive mechanism is fixedly connected inside the base. A grinding mechanism is connected to the drive mechanism. A set of sanding belts is provided on the grinding mechanism. The sanding belts are located on both sides of the corrosion-resistant composite pipe. A dust suction pipe is also provided on the grinding mechanism. A flexible hose is connected to the bottom of the dust suction pipe. The other end of the flexible hose is connected to a vacuum cleaner.

[0005] Furthermore, the first fixing mechanism includes a first fixing seat fixed on the base, a first bearing fixedly connected to the first fixing seat, a first rotating shaft passing through the first rotating shaft, a first belt conveyor connected to one end of the first rotating shaft and a first fixing plate fixedly connected to the other end, a first limiting plate fixedly connected to the first fixing plate, and a corrosion-resistant composite pipe sleeved on the first limiting plate and abutting against the first fixing plate.

[0006] Furthermore, the second fixing mechanism includes a second fixing seat fixed on the base, a set of slide bars fixedly connected to the second fixing seat, a slide groove slidably connected to the slide bars, a slide plate fixedly connected to the slide groove, a slide block fixedly connected to the slide plate, a second bearing fixedly connected inside the slide block, a second rotating shaft connected to the second bearing, a second fixing plate and a second limiting plate fixedly connected to the outer end of the second rotating shaft, one end of the anti-corrosion composite pipe being sleeved on the second limiting plate and abutting against the second fixing plate, and also includes a support fixed on the base, an electric actuator fixedly connected to the support, and the output end of the electric actuator being fixedly connected to the slide block.

[0007] Furthermore, the drive mechanism includes a first bearing seat and a second bearing seat fixed inside the base. The bearings on the first bearing seat and the second bearing seat are connected to a threaded rod. One end of the threaded rod is connected to a second belt conveyor. A fixed beam is fixedly connected to the second belt conveyor. The fixed beam is fixed inside the base. The mechanism also includes a slide rod fixed inside the base. A grinding mechanism is connected to both the threaded rod and the slide rod.

[0008] Furthermore, the grinding mechanism includes a movable seat with threaded holes and sliding holes. The threaded rod and the threaded hole are threadedly connected, and the sliding rod and the sliding hole are slidably connected. A frame is fixedly connected to the movable seat, and a suction pipe is embedded in the center of the frame. First springs are fixedly connected to the frame on both sides of the suction pipe. Dust covers are connected to the first springs. Each dust cover consists of a horizontal plate, a vertical plate, an inclined plate, and a side plate. The bottom of the side plate is located above the suction pipe, and there is a gap between the two side plates. A set of spring columns is fixedly connected to the side wall of the dust cover. A clamping plate is fixedly connected to the end of the spring column, and a sanding belt is fixedly connected to the clamping plate.

[0009] Furthermore, the spring column includes a sleeve fixed to the inner wall of the dust cover, a circular plate fixedly connected inside the sleeve, a circular limiting plate movably connected inside the sleeve, a clamping rod fixedly connected to the circular limiting plate, one end of the clamping rod movably passing through the circular plate and the other end fixedly connected to the clamping plate, a second spring sleeved on the clamping rod, one end of the second spring connected to the circular plate and the other end fixedly connected to the circular limiting plate, a limiting groove provided inside the sleeve, a limiting block provided at the end of the clamping rod, and the limiting block slidably disposed in the limiting groove.

[0010] The present invention has the following advantages: When the sanding belt on the grinding mechanism moves back and forth to grind the outer surface of the rotating anti-corrosion composite pipe, the grinding mechanism cleverly utilizes the frictional contact between the sanding belt and the rough outer surface of the anti-corrosion composite pipe to make the entire grinding mechanism vibrate while grinding. This allows the dust generated by the sanding belt grinding the anti-corrosion composite pipe and adhering to and accumulating on the inner wall of the dust cover to be more smoothly drawn down the inner wall of the dust cover and absorbed by the dust suction pipe, reducing the accumulation of dust on the inner wall of the dust cover and affecting the use of the dust cover.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figure 1-9 This invention provides a corrosion-resistant composite pipe and its grinding equipment, including a base 1. A first fixing mechanism and a second fixing mechanism are fixedly connected to the base 1. A corrosion-resistant composite pipe 2 is fixedly connected between the first fixing mechanism and the second fixing mechanism. The corrosion-resistant composite pipe 2 is movably clamped and fixed by the first fixing mechanism and the second fixing mechanism, which can drive the corrosion-resistant composite pipe 2 to rotate. A driving mechanism is fixedly connected inside the base 1. A grinding mechanism is connected to the driving mechanism. The driving mechanism drives the grinding mechanism to move back and forth. A set of sanding belts 3 is provided on the grinding mechanism. The sanding belts 3 are located on both sides of the corrosion-resistant composite pipe 2. The anti-corrosion composite tube 2 is clamped at the center of both sides. Through the rotation of the anti-corrosion composite tube 2, it generates intense friction with the horizontally reciprocating sanding belt 3, which in turn causes the sanding belt 3 to grind the anti-corrosion composite tube 2. The grinding mechanism is also equipped with a dust suction pipe 4, and a hose 5 is connected to the bottom of the dust suction pipe 4. The other end of the hose 5 is connected to a vacuum cleaner. The vacuum cleaner is existing technology and is not shown in this solution. The connection between the vacuum cleaner and the hose 5 ensures the flexibility of the hose 5 and the dust suction pipe 4 when moving with the grinding mechanism, and does not affect the vacuum cleaner. When the vacuum cleaner is started, the dust suction pipe 4 generates negative pressure, which absorbs dust until it enters the vacuum cleaner.

[0023] The first fixing mechanism includes a first fixing seat 6 fixed on the base 1, a first bearing 7 fixedly connected to the first fixing seat 6, a first rotating shaft 8 passing through the first rotating shaft 7, a first belt conveyor 9 connected to one end of the first rotating shaft 8, and a first fixing plate 10 fixedly connected to the other end. The first belt conveyor 9 is existing technology and, like common belt conveyors, consists of a motor, a driving pulley, a belt, and a driven pulley. The driven pulley is connected to the first rotating shaft 8 and drives the first rotating shaft 8 to rotate on the first bearing 7. A first limiting plate 11 is fixedly connected to the first fixing plate 10. The first rotating shaft 8 drives the first fixing plate 10 and the first limiting plate 11 to rotate. One end of the anti-corrosion composite pipe 2 is sleeved on the first limiting plate 11 and abuts against the first fixing plate 10.

[0024] The second fixing mechanism includes a second fixing seat 12 fixed on the base 1. A set of slide bars 13 are fixedly connected to the second fixing seat 12. A slide groove 14 is slidably connected to the slide bar 13. A slide plate 15 is fixedly connected to the slide groove 14. A slide block 16 is fixedly connected to the slide plate 15. When the slide block 16 moves, it drives the slide plate 15 and the slide groove 14 to move horizontally on the slide bar 13.

[0025] A second bearing 17 is fixedly connected inside the slide 16. A second rotating shaft 18 is connected to the second bearing 17. A second fixed plate 19 and a second limiting plate 20 are fixedly connected to the outer end of the second rotating shaft 18. When the second rotating shaft 18 rotates on the second bearing 17, it drives the second fixed plate 19 and the second limiting plate 20 to rotate. One end of the anti-corrosion composite tube 2 is sleeved on the second limiting plate 20 and abuts against the second fixed plate 19. It also includes a support 21 fixed on the base 1. An electric push rod 22 is fixedly connected to the support 21. The output end of the electric push rod 22 is fixedly connected to the slide 16. The electric push rod 22 drives the slide 16 to move horizontally left and right.

[0026] The drive mechanism includes a first bearing seat 23 and a second bearing seat 24 fixed inside the base 1. The bearings on the first bearing seat 23 and the second bearing seat 24 are connected to a threaded rod 25. One end of the threaded rod 25 is connected to a second belt conveyor 26. The second belt conveyor 27 is the same as the first belt conveyor 9 mentioned above and is also existing technology. Therefore, the driven pulley of the second belt conveyor 29 is connected to the threaded rod 25. The second belt conveyor 29 drives the threaded rod 25 to rotate on the bearings on the first bearing seat 23 and the second bearing seat 24. A fixed beam 27 is fixedly connected to the second belt conveyor 26. The fixed beam 27 is fixed inside the base 1. It also includes a slide rod 28 fixed inside the base 1. A grinding mechanism is connected to the threaded rod 25 and the slide rod 28.

[0027] The grinding mechanism includes a movable base 29, which is provided with a threaded hole 30 and a sliding hole 31. A threaded rod 25 is threadedly connected to the threaded hole 30, and a sliding rod 28 is slidably connected to the sliding hole 31. When the threaded rod 25 rotates, it is limited by the sliding rod 28. With the forward and reverse rotation of the second belt conveyor 26, the movable base 29 moves back and forth on the threaded rod 25 and the sliding rod 28. A frame 32 is fixedly connected to the movable base 29. A dust suction pipe 4 is embedded in the center of the frame 32. First springs 33 are fixedly connected to both sides of the dust suction pipe 4 on the frame 32. Dust shields 34 are connected to the first springs 33. Each dust shield 34 is composed of a horizontal plate, a vertical plate, an inclined plate, and a side plate. The above structure not only enables the dust cover 34 to form a cover and block dust, but also allows the dust adhering to the inner wall of the dust cover 34 to fall naturally along the inclined plate of the dust cover 34. The bottom of the side plate is located above the suction pipe 4 and there is a gap between the two side plates to ensure that the falling dust can fall more concentratedly at the opening of the suction pipe 4. A set of spring columns 35 are fixedly connected to the side wall of the dust cover 34. The ends of the spring columns 35 are fixedly connected to the clamps 36. The sanding belt 3 is fixedly connected to the clamps 36. The two ends of the sanding belt 3 are fixed by the clamps 36. Through the elasticity of the spring columns 35, the sanding belt 3 is always clamped tightly to the anti-corrosion composite pipe 2 to prevent the sanding belt 3 from detaching from the anti-corrosion composite pipe 2.

[0028] The spring post 35 includes a sleeve 37 fixed to the inner wall of the dust cover 34. A circular plate 38 is fixedly connected inside the sleeve 37. The circular plate 38 does not move inside the sleeve 37. A circular limiting plate 39 is also movably connected inside the sleeve 37. A clamping rod 40 is fixedly connected to the circular limiting plate 39. The circular limiting plate 39 moves inside the sleeve 37 as the clamping rod 40 moves. One end of the clamping rod 40 movably passes through the circular plate 38, and the other end is fixedly connected to a clamping plate 36. The clamping rod 40 movably passes through the circular plate 38 and moves back and forth. A second spring 41 is sleeved on the clamping rod 40. One end of the second spring 41 is connected to the circular plate 38, and the other end is fixedly connected to the circular limiting plate 39. When the circular limiting plate 39 moves back and forth inside the sleeve 37, the second spring 41 is compressed or rebounded between the circular plate 38 and the circular limiting plate 39.

[0029] The sleeve 37 is provided with a limiting groove 42 inside, and the end of the clamping rod 40 is provided with a limiting block 43. The limiting block 43 is slidably disposed in the limiting groove 42. When the clamping rod 40 moves back and forth in the sleeve 37, it drives the limiting block 43 to move in the limiting groove 42, preventing the clamping rod 40 from rotating when it moves back and forth in the sleeve 37, which would cause the sanding belt 3 to rotate and its position to be unstable, thus preventing the sanding belt 3 from properly grinding the anti-corrosion composite pipe 2.

[0030] The working principle of this invention is as follows: One end of the anti-corrosion composite tube 2 is inserted into the first limiting plate 11, and the other end is aligned with the center of the second limiting plate 20. The electric push rod 22 is activated, and the electric push rod 22 pushes the slide block 16 close to one end of the anti-corrosion composite tube 2. The slide block 16 drives the slide plate 15 and the slide groove 14 to move on the slide bar 13, and at the same time drives the second fixing plate 19 and the second limiting plate 20 to move until the second limiting plate 20 is inserted into the anti-corrosion composite tube 2. The anti-corrosion composite tube 2 is fixed between the first fixing plate 10 and the second fixing plate 19 and is clamped. The anti-corrosion composite tube 2 is clamped by the sand belts 3 on both sides.

[0031] Start the first belt conveyor 9, which drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the first fixed plate 10 and the first limiting plate 11 to rotate. The first limiting plate 11 drives the anti-corrosion composite pipe 2 and the second fixed plate 19 to rotate.

[0032] The second belt conveyor 26 is started, which drives the threaded rod 25 to rotate. The threaded rod 25 rotates within the threaded hole 30 and is limited by the sliding rod 28, causing the moving seat 29 to move horizontally left and right on the threaded rod 25. The sliding hole 31 moves horizontally on the sliding rod 28. The moving seat 29 drives the entire grinding mechanism to move slowly left and right horizontally. When the anti-corrosion composite pipe 2 rotates, it grinds with the sanding belt 3. The sanding belt 3 grinds the outer surface of the anti-corrosion composite pipe 2 along its entire length as the moving seat 29 moves. Because the surface of the anti-corrosion composite pipe 2 is rough and it rotates at high speed, it generates vibration when grinding with the sanding belt 3. The vibration is transmitted to the clamping plate 36, spring column 35, dust cover 34 and first spring 33. The first spring 33 elastically supports the dust cover 34, so the entire dust cover 34 is also being ground. During vibration, the second spring 41 in the spring column 35 always provides elastic support to the circular limiting plate 39, so that the circular limiting plate 39 always provides elastic support to the clamping rod 40, the clamping plate 36 on the clamping rod 40, and the sanding belt 3. The sanding belt 3 always presses tightly against the anti-corrosion composite pipe 2. The clamping rod 40 moves through the circular plate 38, and the limiting block 43 slides in the limiting groove 42. When the vacuum cleaner is started, some of the dust generated during grinding is directly absorbed by the suction pipe 4 below, and some is dispersed and blocked by the dust cover 34 and adheres to the inner wall of the dust cover 34. Since the dust cover 34 is always vibrating, the dust adhering to the dust cover 34 is difficult to accumulate on the inner wall of the dust cover 34. The dust adhering to the inner wall of the dust cover 34 falls down along the inclined plate of the dust cover 34 and is absorbed at the opening of the suction pipe 4.

[0033] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
