Description

Technical Field

[0001] This invention relates to the field of rock wool pipe production technology, and in particular to an automatic rock wool pipe production device and production method. Background Technology

[0002] Thermal insulation cotton pipe shells include rock wool pipe shells, glass wool pipe shells, aluminum silicate cotton pipe shells, etc. Using cotton pipe shells is the main method for insulating pipes. The traditional method of producing cotton pipe shells is to first roll the pipe, then shape the rolled cotton pipe, and finally cut and trim the ends of the cotton pipe.

[0003] In the production process of rock wool pipes, it is necessary to roll the cotton felt onto the pipe core. Traditional rolling methods mostly involve manually rolling the cotton felt onto the pipe core, which is not very automated. Therefore, this invention proposes an automatic rock wool pipe production device and production method to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes an automatic rock wool pipe production device and method. This automatic rock wool pipe production device, through a four-station design, can automatically wind the core of the pipe into cotton felt, automatically unload the wound cotton pipe, and install the core of the pipe into the empty station after unloading, greatly increasing the automation level of the device.

[0005] To achieve the objectives of this invention, the following technical solution is provided: An automatic rock wool pipe production device, comprising a thinning machine, a breaking machine, a lifting belt, a winding mechanism, a curing oven, an end cutter, an external cylindrical grinder, a core remover, a core recirculation mechanism, and a longitudinal seam saw. The winding mechanism includes a housing, a control box, an adjusting plate, an elastic fixing mechanism, a core, a winding mechanism, and an auxiliary winding mechanism. A control box for controlling the rotation of the adjusting plate is provided on one outer wall of the housing. Adjusting plates are rotatably mounted on both inner walls of the housing. Four sets of elastic fixing mechanisms are arrayed on each of the two sets of adjusting plates. A core is fixed between two symmetrical sets of elastic fixing mechanisms. A limiting plate is provided at the end of the core. A winding mechanism for driving the core to rotate is provided on the elastic fixing mechanism. The auxiliary winding mechanism is used to assist the core in winding cotton felt. Grooves adapted to the elastic fixing mechanisms are provided on the inner walls of both sides of the housing at the position above the adjusting plate.

[0006] A further improvement is made in that: the elastic fixing mechanism includes a roller, a limiting post, a first spring, a mounting plate, a first fixing plate, a second fixing plate, an arc-shaped plate, and a rolling assembly. The limiting post is slidably mounted on the adjusting plate. One end of the limiting post is rotatably connected to the roller, and the other end of the limiting post is fixedly connected to the mounting plate. The lower ends of the first fixing plate and the second fixing plate are both provided with arc-shaped plates, and the inner wall of the arc-shaped plates is provided with a rolling assembly to assist the rotation of the core.

[0007] A further improvement is that: the adjusting plate is provided with a through hole that matches the limiting post, the inner wall of the through hole is symmetrically provided with a limiting groove, and the limiting post is symmetrically provided with a matching limiting block.

[0008] A further improvement is that the rolling assembly includes a first mounting base and a rotating roller, and multiple sets of first mounting bases are arrayed on the inner wall of the arc-shaped plate, with the rotating roller rotatably mounted on the first mounting base.

[0009] A further improvement is that the winding mechanism includes a winding motor, a first clamping plate, and a second clamping plate. A winding motor is fixed to one side of the mounting plate near the first fixed plate. The winding motor is fixedly connected to the first fixed plate. The output end of the winding motor rotates through the first fixed plate and is fixedly connected to the first clamping plate. Another set of mounting plates is fixedly connected to the second fixed plate. The second clamping plate is rotatably connected to the second fixed plate.

[0010] A further improvement is that the first and second clamping plates have striped patterns on the side closest to the tube core and on both ends of the tube core to increase friction.

[0011] A further improvement is made in that: the auxiliary winding mechanism includes a feeding roller, an upper limit seat, and a lower limit seat. The feeding roller is provided on the side of the housing near the lifting belt. The upper limit seat is located on one side of the tube core, and the lower limit seat is located on one side of the feeding roller. The upper limit seat includes a first support rod, a first semi-circular ring plate, a second spring, a second mounting seat, and a first limiting roller. The first support rod is arranged in a circular array of four groups. Both ends of the first support rod are fixedly connected to the adjusting plate. The first semi-circular ring plate is symmetrically arranged on the side of the first support rod facing the tube core. Multiple groups of second springs are arrayed on the inner wall of the first semi-circular ring plate. Multiple groups of second mounting seats are fixed to one end of the multiple groups of second springs. The first limiting roller is rotatably mounted on the second mounting seat.

[0012] A further improvement is made in that: the lower limit seat includes an electric telescopic rod, a second support rod, an arc-shaped ring plate, a third spring, a third mounting seat, and a second limiting roller. Two sets of electric telescopic rods are symmetrically arranged, and the two sets of electric telescopic rods are fixedly connected to the second support rod. An arc-shaped ring plate is symmetrically arranged at the upward position of the second support rod. Two sets of third mounting seats are arranged on the arc-shaped ring plate. The second limiting roller is rotatably mounted on the third mounting seat. Multiple sets of third springs are arranged between the third mounting seat and the arc-shaped ring plate.

[0013] A further improvement is that the mandrel return mechanism includes a shuttle robot, a mandrel lifting robot, a mandrel return line, and a mandrel winding robot. The shuttle robot is used to move the wound cotton tubes. The mandrel lifting robot works in conjunction with the core remover. The mandrel lifting robot sends the removed cores to the upper mandrel return line. The mandrel return line sends the cores to the top of the winding mechanism and automatically feeds the cores through the mandrel winding robot.

[0014] An automatic rock wool pipe production device and its production method, using the automatic rock wool pipe production device of the above claims, includes the following production steps;

[0015] S1. The cotton felt is cut by a thinning machine, and then the cut cotton felt is transported to a breaking machine for further processing. Finally, the processed cotton felt is sent to the feeding roller of the winding mechanism by a lifting belt.

[0016] S2. The control box drives the adjustment plate to rotate, thereby driving the tube core on the adjustment plate to rotate. One of the four sets of tube cores is rotated to the coiling station, and the rotation of the adjustment plate is stopped. At the same time, one set of tube cores is rotated to the loading and unloading station located diagonally opposite the coiling station. Before the adjustment plate rotates, the electric telescopic rod needs to be started to drive the lower limit seat to move downward.

[0017] S3. The core tube is clamped and fixed by the first clamping plate and the second clamping plate. At the same time, the winding motor is started, which drives the first clamping plate to rotate, thereby driving the core tube and the second clamping plate to rotate synchronously. Simultaneously, the elastic potential energy of the second spring and the third spring pushes the first limiting roller and the second limiting roller to limit the cotton felt, so that the cotton felt can be wound up when the core tube rotates. At the same time, as the cotton felt is wound, the second spring and the third spring can contract synchronously.

[0018] S4. The cotton tube located at the loading and unloading station is grabbed by the shuttle robot and moved to the curing oven for curing. Then, the cotton tube is driven by the shuttle robot to process the end of the cotton tube through the end cutter and the external cylindrical grinder. Finally, it is sent to the core remover for core removal.

[0019] S5. The removed core tube is sent to the core tube return line by the core tube lifting robot, and then the core tube is sent to the loading and unloading station by the core tube winding robot. The core tube is sent between the first clamping plate and the second clamping plate. Then, as the roller moves out of the groove, the limiting column is pushed to fix the first clamping plate and the second clamping plate to fix the core tube, thus completing the automatic feeding of the core tube.

[0020] The beneficial effects of this invention are as follows: The invention adopts an automated design, which makes it easier to roll cotton felt into cotton tubes, greatly increasing production efficiency. At the same time, the four-station design can automatically wind cotton felt into the tube core, automatically unload the wound cotton tube, and install the tube core in the empty station after unloading, which greatly increases the automation level of this device.

[0030] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0031] according to Figure 1-8 As shown in the figure, this embodiment proposes an automatic production device and method for rock wool pipes, including a thinning machine 1, a breaking machine 2, a lifting belt 3, a winding mechanism 4, a curing oven 5, an end cutter 6, an external cylindrical grinder 7, a core remover 8, a core recirculation mechanism, and a longitudinal slit saw 9.

[0032] Thinning machine 1 is used for online planing and feeding of cotton, cutting uncured cotton to the required thickness; tearing machine 2 is used to pull cotton felt to a pre-calculated appropriate size and weight, calculated based on diameter / thickness / density, etc.; lifting belt 3 is used in conjunction with winding mechanism 4 to transport the appropriate cotton felt into the winding mechanism 4 for winding; winding mechanism 4 is used for winding and forming cotton tube shells; curing oven 5 is used to cure the wound cotton tube shells; end cutter 6 is used to cut the ends of the cotton tubes; external cylindrical grinder 7 is used to grind the outer diameter of the cotton tubes; core remover 8 is used to separate the core shaft from the cotton tube; core shaft return mechanism is used to transport the core shaft to the winding mechanism 4 for reuse; longitudinal slit saw 9 is used to longitudinally slit the cotton tubes.

[0033] The winding mechanism 4 includes a housing 14, a control box 15, an adjusting plate 16, an elastic fixing mechanism, a core 17, a winding mechanism, and an auxiliary winding mechanism 18. The control box 15, which controls the rotation of the adjusting plate 16, is located on one outer wall of the housing 14. Adjusting plates 16 are rotatably mounted on both inner walls of the housing 14. The control box 15 controls the start and stop of the rotation of the adjusting plates 16. Four sets of elastic fixing mechanisms are arrayed on each of the two sets of adjusting plates 16. A core 17 is fixed between two symmetrical sets of elastic fixing mechanisms. A limiting plate 47 is provided at the end of the core 17 to prevent the cotton felt from deviating during winding. A winding mechanism that drives the core 17 to rotate is provided on the elastic fixing mechanism. The auxiliary winding mechanism 18 assists the core 17 in rotating. 7. The inner walls of the housing 14 on both sides are provided with grooves 19 that are adapted to the elastic fixing mechanism at the upper end of the adjusting plate 16. The rotation of the adjusting plate 16 drives the core tube 17 and the elastic fixing mechanism to rotate synchronously. The adjusting plate 16 is provided with four stations, including a winding station, a loading and unloading station, a waiting-to-wind-wind station, and a waiting-to-load-unload station. The winding station and the loading and unloading station are diagonally arranged. While the winding station is working, the loading and unloading station is working synchronously. At the same time, the inner side of the housing 14 is provided with grooves 19. With the setting of the elastic fixing mechanism, the core tube 17 is in a loose state when it is in the loading and unloading station, which facilitates loading and unloading. At the same time, the device is fully automated, which greatly reduces the use of manpower and the overall winding efficiency is also high.

[0034] The elastic fixing mechanism includes a roller 20, a limiting post 21, a first spring 22, a mounting plate 23, a first fixing plate 25, a second fixing plate 26, an arc-shaped plate 27, and a rolling assembly. The limiting post 21 is slidably mounted on the adjusting plate 16. One end of the limiting post 21 is rotatably connected to the roller 20, and the other end of the limiting post 21 is fixedly connected to the mounting plate 23. The lower ends of the first fixing plate 25 and the second fixing plate 26 are both provided with arc-shaped plates 27. The inner wall of the arc-shaped plate 27 is provided with a rolling mechanism to assist the rotation of the core tube 17. As the roller 20 rotates on the inner wall of the housing 14, it assists the rotation of the limiting post 21. At the same time, the housing 14 presses the limiting post 21, causing the limiting post 21 to push the mounting plate 23, the first fixing plate 25, and the second fixing plate 26 to move, thereby clamping and fixing the core 17. When the roller 20 rotates to the groove 19, the first spring 22 pushes the roller 20 to move deeper into the groove 19, thereby driving the mounting plate 23, the first fixing plate 25, and the second fixing plate 26 to move and release the clamping of the core 17.

[0035] The adjusting plate 16 is provided with a through hole 28 that matches the limiting post 21. The inner wall of the through hole 28 is symmetrically provided with limiting grooves 29. The limiting post 21 is symmetrically provided with matching limiting blocks 30. By engaging the limiting blocks 30 and the limiting grooves 29, the limiting post 21 is limited, so that the limiting post 21 and the through hole 28 are slidably connected, preventing rotation between the limiting post 21 and the through hole 28.

[0036] The rolling assembly includes a first mounting base 31 and a rotating roller 32. Multiple sets of first mounting bases 31 are arrayed on the inner wall of the arc plate 27. The rotating roller 32 is rotatably mounted on the first mounting base 31. By setting the rotating roller 32, the rotation of the core 17 is assisted during the rolling operation, and the friction generated when the core 17 rotates is reduced.

[0037] The winding mechanism includes a winding motor 24, a first clamping plate 33, and a second clamping plate 34. A set of mounting plates 23 is fixed to the side of the first fixed plate 25 with the winding motor 24 fixedly connected to the first fixed plate 25. The output end of the winding motor 24 rotates through the first fixed plate 25 and is fixedly connected to the first clamping plate 33. Another set of mounting plates 23 is fixedly connected to the second fixed plate 26, and the second clamping plate 34 is rotatably connected to the second fixed plate 26. By starting the winding motor 24, the winding motor 24 drives the first clamping plate 33 to rotate. At the same time, due to the clamping relationship between the first clamping plate 33 and the second clamping plate 34 and the end of the core tube 17, the core tube 17 is driven to rotate, thereby winding the cotton felt.

[0038] The first clamping plate 33 and the second clamping plate 34 are provided with striped patterns on the side of the tube 17 near the core 17 and on both ends of the core 17 to increase friction. The design of the striped patterns increases the friction between the core 17 and the first clamping plate 33 and the second clamping plate 34, thereby ensuring the rotation of the core 17.

[0039] The auxiliary winding mechanism 18 includes a feeding roller 35, an upper limit seat, and a lower limit seat. The feeding roller 35 is located on the side of the housing 14 near the lifting belt 3. The upper limit seat is located on one side of the core 17, and the lower limit seat is located on one side of the feeding roller 35. The upper limit seat includes a first support rod 36, a first semi-circular ring plate 37, a second spring 38, a second mounting base 39, and a first limiting roller 40. The first support rod 36 is arranged in four groups in a circular array. The two ends of the first support rod 36 are fixedly connected to the adjusting plate 16. The first support rod 36 faces one side of the core 17. A first semi-circular ring plate 37 is provided symmetrically on both sides. Multiple sets of second springs 38 are arrayed on the inner wall of the first semi-circular ring plate 37. Multiple sets of second mounting seats 39 are fixed to one end of the multiple sets of second springs 38. A first limiting roller 40 is rotatably mounted on the second mounting seat 39. The feeding roller 35 is used to transport the cotton felt to the core tube 17. At the same time, the elastic potential energy of the second spring 38 pushes the first limiting roller 40 to limit the head of the fed cotton felt, thereby assisting the core tube 17 in winding the cotton felt. Meanwhile, the elastic potential energy of the first spring 22 can prevent the cotton felt from loosening during winding.

[0040] The lower limit seat includes an electric telescopic rod 41, a second support rod 42, an arc-shaped ring plate 43, a third spring 44, a third mounting seat 45, and a second limiting roller 46. Two sets of electric telescopic rods 41 are symmetrically arranged, and the two sets of electric telescopic rods 41 are fixedly connected to the second support rod 42. The arc-shaped ring plate 43 is symmetrically arranged at the upward position of the second support rod 42. Two sets of third mounting seats 45 are arranged on the arc-shaped ring plate 43. The second limiting roller 46 is rotatably mounted on the third mounting seat 45. Multiple sets of third springs 44 are arranged between the third mounting seat 45 and the arc-shaped ring plate 43. The elastic potential energy of the third springs 44 pushes the second limiting roller 46 to limit and fix the cotton felt from the bottom. It works with the first limiting roller 40 to ensure the winding of the cotton felt. At the same time, by starting the electric telescopic rod 41, the second limiting roller 46 is moved downward, thereby exposing the wound cotton tube.

[0041] The mandrel return mechanism includes a shuttle robot 12, a mandrel lifting robot 10, a mandrel return line 11, and a mandrel winding robot 13. The shuttle robot 12 is used to move the wound cotton tubes. The mandrel lifting robot 10 works in conjunction with the core remover 8. The mandrel lifting robot 10 delivers the removed core tubes 17 to the upper mandrel return line 11. The mandrel return line 11 delivers the core tubes 17 above the winding mechanism 4 and passes them through the mandrel winding robot 13. The core tube 17 is automatically fed. The shuttle robot 12 grabs the cotton tube located at the loading and unloading station and moves it to the curing oven 5 for curing. Then, the shuttle robot 12 drives the cotton tube through the end cutter 6 and the external cylindrical grinder 7 to process the end of the cotton tube. Finally, it is sent to the core remover 8 for core removal. Then, the core tube 17 is sent to the core return line 11 by the core lifting robot 10. Then, the core tube 17 is sent to the loading and unloading station by the core winding robot 13.

[0042] The above-mentioned automatic rock wool pipe production device includes the following production steps;

[0043] S1. The cotton felt is cut by the thinning machine 1, and then the cut cotton felt is transported to the breaking machine 2 for further processing. Finally, the processed cotton felt is sent to the feeding roller 35 of the winding mechanism 4 by the lifting belt 3.

[0044] S2. The control box 15 drives the adjustment plate 16 to rotate, thereby driving the tube core 17 on the adjustment plate 16 to rotate. One of the four sets of tube core 17 is rotated to the coiling station, and the rotation of the adjustment plate 16 is stopped. At the same time, one set of tube core 17 is rotated to the loading and unloading station located diagonally opposite the coiling station. Before the adjustment plate 16 rotates, the electric telescopic rod 41 needs to be activated to drive the lower limit seat to move downward.

[0045] S3. The core tube 17 is clamped and fixed by the first clamping plate 33 and the second clamping plate 34. At the same time, the winding motor 24 is started, which drives the first clamping plate 33 to rotate, thereby driving the core tube 17 and the second clamping plate 34 to rotate synchronously. Simultaneously, the elastic potential energy of the second spring 38 and the third spring 44 pushes the first limiting roller 40 and the second limiting roller 46 to limit the cotton felt, so that when the core tube 17 rotates, it can wind up the cotton felt. At the same time, as the cotton felt winds up, the second spring 38 and the third spring 44 can contract synchronously.

[0046] S4. The cotton tube located at the loading and unloading station is grabbed by the shuttle robot 12 and moved to the curing oven 5 for curing. Then, the cotton tube is driven by the shuttle robot 12 to process the end of the cotton tube through the end cutter 6 and the external cylindrical grinder 7. Finally, it is sent to the core remover 8 for core removal.

[0047] S5. The core tube 17 is sent to the core tube return line 11 by the core tube lifting robot 10, and then the core tube 17 is sent to the loading and unloading station by the core tube winding robot 13. The core tube 17 is then sent between the first clamping plate 33 and the second clamping plate. Then, as the roller 20 moves out of the groove 19, the limiting post 21 is pushed to fix the first clamping plate 33 and the second clamping plate 34 to fix the core tube 17, thus completing the automatic loading of the core tube 17.

Multiple sets of third springs (44) are provided between the third mounting seat (45) and the arc-shaped ring plate (43).

7. The automatic rock wool pipe production device according to claim 6, characterized in that: The mandrel return mechanism includes a shuttle manipulator (12), a mandrel lifting manipulator (10), a mandrel return line (11), and a mandrel winding manipulator (13). The shuttle manipulator (12) is used to move the wound cotton tube. The mandrel lifting manipulator (10) is used in conjunction with the core remover (8). The mandrel lifting manipulator (10) sends the removed core tube (17) to the mandrel return line (11) located above. The mandrel return line (11) sends the core tube (17) to the top of the winding mechanism (4) and automatically feeds the core tube (17) through the mandrel winding manipulator (13).

8. An automated method for producing rock wool pipes, characterized in that: The automatic rock wool pipe production device according to claim 7 includes the following production steps; S1. The cotton felt is cut by a thinning machine (1), and then the cut cotton felt is transported to a breaking machine (2) for further processing. Finally, the processed cotton felt is sent to the feeding roller (35) of the winding mechanism (4) by a lifting belt (3). S2. The control box (15) drives the adjustment plate (16) to rotate, thereby driving the tube core (17) on the adjustment plate (16) to rotate. One of the four sets of tube cores (17) is rotated to the coiling station, and the rotation of the adjustment plate (16) is stopped. At the same time, one set of tube cores (17) is rotated to the loading and unloading station located diagonally opposite the coiling station. Before the adjustment plate (16) rotates, the electric telescopic rod (41) needs to be started to drive the lower limit seat to move downward. S3. The core tube (17) is clamped and fixed by the first clamping plate (33) and the second clamping plate (34). At the same time, the winding motor (24) is started. The winding motor (24) drives the first clamping plate (33) to rotate, thereby driving the core tube (17) and the second clamping plate (34) to rotate synchronously. At the same time, the elastic potential energy of the second spring (38) and the third spring (44) respectively pushes the first limiting roller (40) and the second limiting roller (46) to limit the cotton felt, so that when the core tube (17) rotates, it can wind up the cotton felt. At the same time, as the cotton felt is wound, the second spring (38) and the third spring (44) shrink synchronously. S4. The cotton tube located at the loading and unloading station is picked up by the shuttle robot (12) and moved to the curing oven (5) for curing. Then, the cotton tube is driven by the shuttle robot (12) to process the end of the cotton tube through the end cutter (6) and the external cylindrical grinder (7). Finally, it is sent to the core remover (8) for core removal. S5. The removed core (17) is sent to the core return line (11) by the core lifting robot (10). Then, the core (17) is sent to the loading and unloading station by the core winding robot (13). The core (17) is then sent between the first clamping plate (33) and the second clamping plate (34). Then, as the roller (20) moves out of the groove (19), the limiting post (21) is pushed to fix the core (17) between the first clamping plate (33) and the second clamping plate (34), thus completing the automatic loading of the core (17).
