Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0052] See also Figures 1 to 11, shown is a polishing machine for pipes of variable length in an embodiment of the present invention, including an intermediate conveying and adjusting unit 10, a loading rack 21, a unloading rack 22, a bearing mechanism 30, a pipe lifting and transverse movement mechanism 40, a grinding head walking mechanism 50 and a lifting mechanism 60.

[0053] The loading rack 21 and the unloading rack 22 are used for loading and unloading pipes, respectively. The loading rack 21 and the unloading rack 22 are respectively arranged on both sides of the intermediate conveying and adjusting unit 10. The bearing mechanism 30 is provided with two groups, which are respectively arranged at both ends of the intermediate conveying and adjusting unit 10. The pipe lifting and transverse movement mechanism 40 is arranged on the intermediate conveying and adjusting unit 10. The grinding head walking mechanism 50 is provided with two groups, which are respectively arranged at one end of the two bearing mechanisms 30 away from the intermediate conveying and adjusting unit 10. The lifting mechanism 60 is provided with two groups, which are respectively arranged at the two bearing mechanisms 30. The structure 30 is close to one end of the grinding head walking mechanism 50, wherein the pipe lifting and transverse movement mechanism 40 is used to transfer the pipes on the loading rack 21 to the spherical bearing group on the pipe lifting and transverse movement mechanism 40, wherein one of the grinding head walking mechanisms 50 is used to grind and polish the pipes, and transfer the pipes to another grinding head walking mechanism 50 through the intermediate conveying and adjusting unit 10, so that the other grinding head walking mechanism 50 grinds the pipes, and the lifting mechanism 60 is used to adjust the height of the grinding head walking mechanism 50, so that the grinding head walking mechanism 50 can adapt to pipes of different diameters.

[0054] It needs to be explained that the pipe is transported by the pipe lifting and transverse movement mechanism 40 so that both ends of the pipe can be polished on the same device, and the position of the pipe is adjusted by the pipe lifting and transverse movement mechanism 40 so that the polishing machine can polish pipes of different lengths.

[0055] Specifically, in this embodiment, the intermediate conveying and adjusting unit 10 includes a plurality of height adjustment mechanisms 13 and a plurality of conveying and adjusting mechanisms 14, and the plurality of height adjustment mechanisms 13 and the plurality of conveying and adjusting mechanisms 14 are arranged alternately. The intermediate conveying and adjusting unit 10 also includes a frame cover 11, and a plurality of lifting windows 12 are provided on both sides of the frame cover 11. The plurality of height adjustment mechanisms 13 and the plurality of conveying and adjusting mechanisms 14 are arranged in the frame cover 11.

[0056] It should be explained that, in this embodiment, the height adjustment mechanism 13 can adjust the height of the pipe, and can bring the pipe on the loading rack 21 into the intermediate adjustment unit 10, and make the height of the pipe reach the preset position for polishing and transportation, and the transportation adjustment mechanism 14 can stably transport the pipe and adjust the height of the pipe, so that the pipe can be polished at a preset height.

[0057] It is worth noting that the intermediate adjustment unit 10 is fully enclosed to prevent polishing dust from overflowing, isolate noise and form a closed space to ensure the effect of dust removal and ventilation. There are lifting windows 12 on both sides of the loading and unloading, which is convenient for observing the internal operation of the machine. It is worth noting that in other optional embodiments, due to the long span of the lifting window 12, the transmission method adopts the gear rack plus slider guide rail method, which can ensure the stability and consistency of lifting.

[0058] Furthermore, in this embodiment, the height adjustment mechanism 13 includes an adjusting cylinder 131, two guide columns 132, a mounting plate 133 and a pipe transfer wedge plate 134. The adjusting cylinder 131 is arranged at the bottom of the frame cover 11, and the output end of the adjusting cylinder 131 is connected to the pipe transfer wedge plate 134 through the mounting plate 133. The two guide columns 132 are connected to the two ends of the bottom of the mounting plate 133.

[0059] It can be understood that starting the adjusting cylinder 131 causes the adjusting cylinder 131 to drive the mounting plate 133 to move up and down, thereby causing the mounting plate 133 to drive the pipe-moving wedge plate 134 to move up and down, and then the pipe-moving wedge plate 134 can drive the pipe to move up and down, so that the pipe can reach a preset height, thereby achieving the purpose of adjusting the height of the pipe. In addition, when the mounting plate 133 is moving up and down, the guide column 132 follows the moving up and down, so that the mounting plate 133 is more stable when moving up and down.

[0060] Furthermore, in the present embodiment, the plurality of conveying and adjusting mechanisms 14 include an ultra-thin cylinder 141, a fixed slide 142, a plurality of guide shafts 143, a base frame 144, a first motor 145, a conveyor belt 146 and a plurality of conveyor rollers 147. The ultra-thin cylinder 141 is arranged at the bottom of the frame cover 11, the fixed slide 142 is arranged at the output end of the ultra-thin cylinder 141, the base frame 144 is connected to the upper surface of the fixed slide 142 through the plurality of guide shafts 143, the first motor 145 is arranged on the base frame 144, the output pipe of the first motor 145 passes through the side wall of the base frame 144 and is connected to one end of the conveyor belt 146, the other end of the conveyor belt 146 is connected to one of the conveyor rollers 147, and the plurality of conveyor rollers 147 are arranged on the upper surface of the base frame 144.

[0061] It can be understood that when the height of the pipe is being adjusted, the ultra-thin cylinder 141 is started, so that the ultra-thin cylinder 141 drives the base frame 144 to rise and fall via the fixed slide 142, so that the base frame 144 drives the first motor 145, the transmission belt 146 and the conveying roller 147 to rise and fall, and the conveying roller 147 is in contact with the pipe, and then the first motor 145 is started, so that the first motor 145 drives the conveying roller 147 to rotate through the conveyor belt 146, so that the conveying roller 147 drives the pipe to move in the intermediate conveying and adjusting unit 10, and the pipe reaches the designated position for grinding. In addition, during the lifting process of the base frame 144, the guide shaft 143 can assist the base frame 144 to lift and fall stably.

[0062] Specifically, in the present embodiment, the pipe lifting and transverse movement mechanism 40 is provided on one side of the plurality of height adjustment mechanisms 13, and the pipe lifting and transverse movement mechanism 40 comprises a transverse movement guide rail mounting plate 41, a transverse movement guide rail 42, a pipe lifting and transverse movement plate 43, a rack fixing plate 44, a transverse movement gear 45, a spherical bearing group 46 and a transmission chain 47, the transverse movement guide rail mounting plate 41 is arranged at the bottom of the frame cover 11, the transverse movement guide rail 42 is provided on the upper surface of the transverse movement guide rail mounting plate 41, and the transverse movement guide rail 42 is provided with the lifting gear matched therewith. The pipe transverse shifting plate 43, the guide column 132 passes through the pipe lifting transverse shifting plate 43, the rack fixing plate 44 is meshed with the transverse shifting gear 45, the middle of the transverse shifting gear 45 is connected with a transmission rod 49, and the transmission rod 19 is respectively connected to several of the pipe lifting transverse shifting mechanisms 40, the access end of the spherical bearing group 46 is connected to one end of the transmission chain 47, and the other end of the transmission chain 47 is connected to a hexagonal transmission rod 48, and the hexagonal transmission rod 48 is connected to one end of the transmission chain 47 on several of the pipe lifting transverse shifting mechanisms 40.

[0063] It can be understood that the pipe lifting and transverse shifting plate 43 can be laterally moved based on the transverse shifting guide rail mounting plate 41 and the transverse shifting guide rail 42, so that the spherical bearing group 46 of the pipe lifting and transverse shifting plate 43 is located below the pipe on the loading rack 21, and then the entire pipe lifting and transverse shifting mechanism 40 is pushed up and down by adjusting the cylinder 131, so that the pipe on the loading rack 21 can be lifted and moved into the intermediate conveying and adjusting unit 10, and then transported to the grinding head walking mechanism 50 for grinding through the conveying and adjusting mechanism 14;

[0064] It is worth noting that when the spherical bearing group 46 is driven, the transmission chain 47 transmits power to each group of pipe lifting and transverse movement mechanisms 40 through the hexagonal transmission rod 48, so that the spherical bearing group 46 in each group of pipe lifting and transverse movement mechanisms 40 rotates at the same time to assist the pipe in rotational polishing. In addition, the transverse movement gear 45 is driven by the rack fixing plate 44, so that the transverse movement gear 45 drives the transmission rod 49, and the transmission rod 49 drives each group of pipe lifting and transverse movement mechanisms 40, so that the movement direction of each group of pipe lifting and transverse movement mechanisms 40 is consistent, and the pipes on the loading rack 21 can be lifted and moved at the same time.

[0065] Specifically, in this embodiment, the two bearing mechanisms 30 each include a head machine pipe rack 31 and a pipe rack bottom plate 32, the pipe rack bottom plate 32 is arranged in the head machine pipe rack 31, the upper surface of the head machine pipe rack 31 is provided with a plurality of electric opening and closing roller mechanisms 33, the plurality of electric opening and closing tug mechanisms 33 are equidistantly and symmetrically arranged on the upper surface of the head machine pipe rack 31, the electric opening and closing tug mechanisms 33 are arranged on the head machine pipe rack 31 through a tug seat bottom plate 34, the tug seat bottom plate 34 is arranged on a cylindrical guide rail 36 through a guide rail slider 35, The cylindrical guide rail 36 is arranged on the head machine pipe frame 31, and the guide rail slider 35 cooperates with the cylindrical guide rail 36. The opening and closing wheel mechanism 33 includes a driving part 331, an upper tug wheel 332, a mounting seat 333 and a lower tug wheel 334. The mounting seat 333 is arranged on the upper surface of the tug wheel seat bottom plate 34, the driving part 331 is arranged on the top of the mounting seat 333, and the output end of the driving part 331 is connected to the upper tug wheel through the guide part 335, and the lower tug wheel 334 is connected to the side wall of the mounting seat 333.

[0066] It can be understood that when the pipe reaches the head machine pipe rack 31, a support sleeve is first sleeved on the outer circumference of the pipe, and a support sleeve is installed on the pipe at intervals. The support sleeve and the inner wall of the pipe play a supporting role to prevent the pipe from extending too long during the polishing process, causing shaking, and thus affecting the polishing effect. The driving part 331 opens the distance between the upper tug wheel 332 and the lower tug wheel 334 through the guide part 335, so that the pipe passes through it. After passing through, the upper tug wheel 332 and the lower tug wheel 334 are closed to support the pipe. By only driving the upper tug wheel 332, space can be saved to save costs. Secondly, when replacing the throwing rod, it is convenient to take out the throwing rod from the side.

[0067] It should be noted that one group of bearing mechanisms 30 is provided with four groups of opening and closing roller mechanisms 33. The upper tug wheel 332 and the lower tug wheel 334 in the opening and closing roller mechanism 33 near the grinding head walking mechanism 50 are opened manually, and the pipe at this position does not need to be supported by the support sleeve. It is worth noting that the support sleeve is sleeved on the outer wall of the pipe (casting rod) to support the pipe (casting rod). The driving part 331 in the other three groups of opening and closing roller mechanisms 33 opens the distance between the upper tug wheel 332 and the lower tug wheel 334 through the electric drive guide part 335, and the upper tug wheel 332 and the lower tug wheel 334 are used to support the pipe after the support sleeve is sleeved, so they need to be opened electrically, and the distance between the upper tug wheel 332 and the lower tug wheel 334 can be opened manually without the support of the support sleeve.

[0068] Each set of opening and closing roller mechanism 33 has two rows of tugwheels, namely the upper tugwheel 332 and the lower tugwheel 334, which press down the pipe (casting rod) to fix and support the pipe (casting rod). The tugwheels of the conventional roller support seat are fixed and cannot be opened and tightened. Since the pipe (casting rod) is wrapped with high-temperature tape or other fixing rings, it is required to open the position where the pipe (casting rod) is wrapped with high-temperature tape when it moves close to the opening and closing roller mechanism 33 to allow the pipe to pass. After passing, the upper tugwheel 332 and the lower tugwheel 334 are closed to continue to fix and support the pipe (casting rod).

[0069] Specifically, in the present embodiment, the two grinding head walking mechanisms 50 each include a motor seat 51, two second motors 52, two poly-V belts 53 and two spring chucks 54, the motor seat 51 is arranged on the upper surface of the supporting mechanism 30, the two second motors 52 are symmetrically arranged on the upper surface of the motor seat 51, the output ends of the two second motors 52 are respectively connected to one end of the two poly-V belts 53, and the other ends of the two poly-V belts 53 are respectively connected to the two spring chucks 54, the bottom of the motor seat 51 is evenly connected with a plurality of slide rails 55, the upper surface of the supporting mechanism 30 is provided with a plurality of guide pillars 56, and the plurality of slide rails 55 are slidably sleeved on the guide pillars 56.

[0070] It can be understood that by starting the second motor 52 and driving the spring chuck 54 via the poly-V belt 53, the pipe is polished, and the motor seat 51 can move laterally through the slide rail 55 and the guide column 56, so that the second motor 52, the poly-V belt 53 and the spring chuck 54 can all move laterally, so that the distance between the second motor 52, the poly-V belt 53 and the spring chuck 54 and the intermediate conveying adjustment unit 10 can be adjusted, thereby clamping pipes of different lengths.

[0071] Specifically, in the present embodiment, the two lifting mechanisms 60 each include a lifting driver 61, a plurality of transmission parts 62, a drive shaft 63, and a transmission lifting plate 64. The lifting driver 61 is disposed in the supporting mechanism 30. The output end of the lifting driver 61 is connected to the drive shaft 63, and the drive shaft 63 passes through the plurality of transmission parts 62 in sequence. The transmission lifting plate 64 is connected to the output end of the transmission part 62, and the grinding head walking mechanism 50 is disposed on the upper surface of the transmission lifting plate 64.

[0072] It can be understood that, in a specific implementation, the lifting drive 61 starts to drive the driving shaft 63, the driving shaft 63 drives several transmission parts 62 to output power at the same time, and the transmission part 62 drives the lifting plate 64 to lift and lower, so that the lifting plate 64 can drive the motor seat 51, the two second motors 52, the two multi-V belts 53 and the two spring clamps 54, the slide rail 55 and the guide column 56 to lift and lower, thereby completing the height adjustment, and then being able to adapt to pipes of different diameters.

[0073] Specifically, in this embodiment, both ends of the intermediate conveying and regulating unit 10 are provided with a stopper mechanism 15, and the stopper mechanism 15 includes a baffle 151, a pipe sleeve 152, a bearing seat 153 and a lifting part 154, the lifting part 154 is arranged at the bottom of both ends of the intermediate conveying and regulating unit 10, the bearing seat 153 is arranged at the output end of the lifting part 154, the baffle 151 is arranged on the upper surface of the bearing seat 153, and the pipe sleeve 152 is arranged on the side wall of the baffle 151;

[0074] It is understandable that the outer diameter of the flexible grinding head is usually larger than the inner diameter of the pipe, and the inner wall polishing of a pipe can only meet the requirements after multiple grindings. When the grinding head enters the pipe mouth multiple times, it is inevitable that the pipe mouth will be damaged, such as forming a conical surface or chamfer at the pipe mouth. Therefore, a stopper mechanism 15 is added, and a pipe sleeve 52 is installed on the stopper mechanism 15. The pipe sleeve 52 can move forward and backward along the axial direction of the pipe. Before the grinding head enters the pipe mouth, the pipe sleeve 52 moves forward and fits the pipe end to prevent the grinding head from entering and damaging the pipe mouth. In addition, during the polishing process, the pipe sleeve 52 can rotate with the pipe. When processing pipes of different specifications and diameters, the corresponding pipe sleeve 52 can be replaced, and the pipe sleeve 52 can be raised and lowered to ensure that the pipe sleeve 52 is coaxial with the pipe.

[0075] A blowing mechanism 16 is provided above the head blocking mechanism 15, and the blowing mechanism 16 includes a connecting plate 161, a blowing portion 162, and a plurality of groups of air nozzles 163. The connecting plate 161 is connected to the top of the intermediate conveying and regulating unit 10, the top of the blowing portion 162 is connected to the top inside the intermediate conveying and regulating unit 10, the side wall of the blowing portion 162 is connected to the side wall of the connecting plate 161, and the plurality of groups of air nozzles 163 are connected to the output end of the blowing portion 162;

[0076] It can be understood that both ends of the intermediate conveying and regulating unit 10 are equipped with blowing mechanisms 16. When polishing is completed, the air nozzle 163 moves downward and close to the pipe mouth to blow out the dust left in the pipe after polishing, thereby cleaning the inside of the pipe.

[0077] A pipe pressing rubber wheel mechanism 17 is provided at the top of the intermediate conveying and regulating unit 10. The pipe pressing rubber wheel mechanism 17 includes a longitudinal cylinder 171, a connecting piece 172, two sliding hoops 173 and a plurality of pipe pressing wheel groups 174. The longitudinal cylinder 171 is connected to the top of the intermediate conveying and regulating unit 10, the output end of the longitudinal cylinder 171 is connected to the connecting piece 172, the two sliding hoops 173 are symmetrically connected to the two ends of the connecting piece 172, and the plurality of pipe pressing wheel groups 174 are connected to the bottom of the connecting piece 172.

[0078] It can be understood that each set of pipe lifting and transverse movement mechanism 40 corresponds to a set of pipe pressing wheel set 174. During the polishing process of the pipe, the pipe pressing wheel set 174 presses on the top of the pipe, and the pipe pressing wheel set 174 rotates with the supporting wheel and the pipe to play a stabilizing role. And each set of pipe pressing wheel set 174 can adjust the horizontal position through the sliding hoop 173, and the sliding hoop 173 is set on the crossbeam at the top of the frame cover 11 (not shown in the figure).

[0079] Specifically, in this embodiment, chain scraper mechanisms 18 are provided at both ends of the bottom of the intermediate conveying and adjusting unit 10, and the chain scraper mechanism 18 includes a servo motor 181, an output shaft 182, two scraping chains 183 and a collecting box 184. The servo motor 181 is connected to the bottom side wall of the intermediate conveying and adjusting unit 10, and the output shaft 182 is connected to the output end of the servo motor 181. The two scraping chains 183 are respectively sleeved on the two ends of the output shaft 182, and the collecting box 184 is arranged below the output shaft 182 and connected to the side wall of the intermediate conveying and adjusting unit 10.

[0080] It is understandable that, in specific implementation, the servo motor 181 is started, and the servo motor 181 drives the output shaft 182, so that the output shaft 182 drives the scraper chain 183 to operate, so that the accumulated dust can be scraped out of the machine, which is convenient for cleaning the machine. Compared with the belt conveyor, the scraper chain 183 is used as a conveyor, which is more durable and more convenient for later maintenance. Due to the limited space at the bottom of the machine, it is inconvenient or impossible to replace the belt, and the accumulated dust is brought to the collection box 184 for collection.

[0081] In summary, the variable-length pipe polishing machine in the above-mentioned embodiment of the present invention transmits the pipe to be polished to the supporting mechanism 30 through the pipe lifting and transverse movement mechanism 40, and transmits the pipe to one of the grinding head walking mechanisms 50 through the intermediate conveying unit 10, so that the grinding head walking mechanism 50 polishes the pipe, and after the polishing of one end of the pipe is completed, the pipe is transmitted to the other grinding head walking mechanism 50 through the intermediate conveying unit 10, so that the other grinding head walking mechanism 50 polishes the other end of the pipe, and the height of the grinding head walking mechanism 50 is adjusted by the lifting mechanism 60, so as to adapt to the polishing of pipes of different diameters, so that the variable-length pipe polishing machine can polish pipes of different lengths and diameters, effectively improving the pipe polishing efficiency.
