Description

Technical Field

[0001] This invention relates to the field of marine plastic pipe fittings processing technology, specifically to a surface smoothing device for marine plastic pipe fittings. Background Technology

[0002] Marine plastic piping components are non-metallic pipe assemblies used in ship piping systems to transport fluid media. They have functions such as fluid transport, corrosion protection, lightweight design, and high safety performance. Since the surface smoothness of marine plastic piping components directly affects fluid resistance, cleaning efficiency, and sealing performance, surface smoothness treatment equipment is required during the production and processing of marine plastic piping components to ensure that the surface smoothness of marine plastic piping components meets the standards.

[0003] In existing technologies, most surface smoothing devices for marine plastic pipe fittings are unidirectional grinding and polishing. Due to the friction in one direction, the surface texture is obviously directional, which easily produces periodic scratches and high surface roughness. This results in uneven surface quality of the marine plastic pipe fittings after grinding and polishing. Furthermore, viscoelastic materials such as plastics are prone to local accumulation or tearing under unidirectional grinding and polishing cutting, forming burrs or cracks. This reduces the yield of the marine plastic pipe fittings after grinding. In addition, unidirectional grinding requires multiple rounds of grinding to complete the grinding of the marine plastic pipe fittings, resulting in low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problems that most surface smoothing devices for marine plastic pipe fittings are unidirectional grinding and polishing devices. Due to the unidirectional friction, the surface texture is obviously directional, which easily produces periodic scratches and high surface roughness. This results in uneven surface quality of the marine plastic pipe fittings after grinding and polishing. Furthermore, viscoelastic materials such as plastics are prone to local accumulation or tearing under unidirectional grinding and polishing cutting, forming burrs or cracks, which reduces the yield of the finished marine plastic pipe fittings after grinding.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The positive annular grinding plate drives gear three to rotate. Because the annular rack one, gear four and gear three mesh with each other, gear three drives gear four to rotate, and gear four drives annular rack one to rotate. The rotation direction of annular rack one is opposite to that of gear three. At this time, annular rack one drives the negative annular grinding plate to rotate through the annular block. The positive annular grinding plate rotates in the forward direction to grind, and the negative annular grinding plate rotates in the reverse direction to grind, thus forming a relative rotational friction trajectory.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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. Example 1:

[0020] Please see Figures 1-7As shown, a surface smoothing device for marine plastic pipe fittings includes a base 1; a fixing mechanism 2 is provided at the top of the outer wall of the base 1; the fixing mechanism 2 includes a fixing plate 201; a motor 3 is fixedly connected to the top of the outer wall of the fixing plate 201; a threaded shaft 4 is provided at the output end of the motor 3; a connecting plate 5 is threadedly connected to the outer wall of the threaded shaft 4; a positive annular grinding plate 6 is rotatably connected to the inner wall of the connecting plate 5; a reverse grinding mechanism 9 is provided at one end of the outer wall of the positive annular grinding plate; a gear 7 is slidably connected to the outer wall of the threaded shaft 4, and one end of the outer wall of the gear 7 is rotatably connected to one side of the outer wall of the connecting plate 5; a gear 8 is fixedly connected to the outer wall of the positive annular grinding plate 6, and the gear 8 meshes with the gear 7. By using the fixing mechanism 2 to fix the marine plastic pipe fitting, the positive annular grinding plate 6 is sleeved on the marine plastic pipe fitting. The motor 3 drives the threaded shaft 4 to rotate, because the threaded shaft 4 and the connecting plate 5 are connected to the connecting plate 5. The threaded connection of plate 5 causes the rotation of the threaded shaft 4 to move the connecting plate 5 and the positive annular grinding plate 6. The rotation of the threaded shaft 4 also drives the rotation of gear 7. Since gear 7 and gear 8 mesh with each other, gear 7 drives gear 8 to rotate, thereby driving the positive annular grinding plate 6 to rotate. The positive annular grinding plate 6 moves and rotates while grinding. Then, the reverse grinding mechanism 9 simultaneously grinds the marine plastic pipe fittings. This application uses cross-friction trajectory to perform multi-directional cutting on the surface of the marine plastic pipe fittings, eliminating unidirectional scratches, reducing surface roughness, and reducing material accumulation. This solves the problem of burrs and cracks that are easy to occur in unidirectional grinding. Multi-directional grinding can complete multi-directional processing in a single pass, thereby shortening grinding time, improving grinding efficiency and effect, and the frictional heat distribution of multi-directional grinding is uniform, reducing the risk of local overheating, eliminating the need for frequent shutdowns for cooling, and enhancing continuous operation capability.

[0021] The reverse grinding mechanism 9 includes a connecting plate 2 901; the connecting plate 2 901 is threadedly connected to the threaded shaft 4; a reverse annular grinding plate 902 is rotatably connected to the inner wall of the connecting plate 2 901; one end of the outer wall of the reverse annular grinding plate 902 is rotatably connected to one end of the outer wall of the positive annular grinding plate 6; a gear 3 903 is fixedly connected to the outer wall of the positive annular grinding plate 6; a gear 4 904 is rotatably connected to one side of the outer wall of the connecting plate 1 5 via a rotating rod 1; an annular rack 1 905 is fixedly connected to the outer wall of the reverse annular grinding plate 902 via an annular block; the annular rack 1 905, gear 4 904, and gear 3 903 mesh with each other. When the positive annular grinding plate 6 rotates, the positive annular grinding plate 6 drives the gear 3 903 to rotate. The gears mesh with each other, causing gear three 903 to drive gear four 904 to rotate, and gear four 904 to drive annular rack one 905 to rotate. The rotation direction of annular rack one 905 is opposite to that of gear three 903. At this time, annular rack one 905 drives the reverse annular grinding plate 902 to rotate through the annular block, so that the positive annular grinding plate 6 rotates in the forward direction for grinding, and the reverse annular grinding plate 902 rotates in the reverse direction for grinding, thereby forming a relative rotational friction trajectory. This causes the contact points between the positive annular grinding plate 6, the reverse annular grinding plate 902 and the surface of the marine plastic pipe fitting to produce multi-directional, cross-cutting action, which solves the problem of uneven surface texture caused by grinding in a single direction. In addition, this application uses reverse friction to promote the shedding of debris, improve the material removal efficiency, and improve the surface smoothness of the marine plastic pipe fitting.

[0022] The bottom of the outer wall of the fixed plate 201 is fixedly connected to the top of the outer wall of the base 1; the top of the outer wall of the base 1 is connected to a threaded rod 202 via a square thread; one end of the outer wall of the threaded rod 202 is rotatably connected to a movable plate 203, and the bottom of the outer wall of the movable plate 203 is slidably connected to the top of the outer wall of the base 1; circular columns 204 are fixedly connected to opposite sides of the outer walls of the movable plate 203 and the fixed plate 201; support fixing rods 205 are fixedly connected to opposite ends of the outer walls of a pair of circular columns 204, and the marine plastic pipe fittings are connected by... A support rod 205 is installed on the fixed plate 201, so that the support rod 205 is engaged with the inner wall of the marine plastic pipe fitting. Then, by rotating the threaded rod 202, the moving plate 203 is moved, so that the support rod 205 on the moving plate 203 is engaged with the inner wall of the marine plastic pipe fitting. At this time, a pair of circular columns 204 press the two sides of the marine plastic pipe fitting and cooperate with the pair of support rods 205 to fix the marine plastic pipe fitting. The radius of the pair of circular columns 204 is smaller than the outer radius of the marine plastic pipe fitting.

[0023] A pair of connecting blocks 1 and 14 slidably connect a ring rack 6 16 to one side of the outer wall of the auxiliary plate 2 14; a circular rod 17 is rotatably connected to one side of the outer wall of the connecting plate 2 901; a gear 6 18 is fixedly connected to one end of the outer wall of the circular rod 17, and the gear 6 18 meshes with the ring rack 6 16; gears 7 19 are fixedly connected to the outer walls of both the reverse ring grinding plate 902 and the circular rod 17, and a pair of gears 7 19 mesh with each other; a set of sliding plates 20 is fixedly connected to one side of the outer wall of the ring rack 6 16; a cleaning block 21 is provided on the inner side wall of the sliding plate 20; one end of the outer wall of the cleaning block 21 is made of cleaning cotton material. When the reverse ring grinding plate 902 rotates, because gears 7 19 are fixedly connected to the outer walls of both the reverse ring grinding plate 902 and the circular rod 17, and a pair of gears 7 19 mesh with each other... The two gears mesh with each other, causing the reverse annular grinding plate 902 to drive the circular rod 17 to rotate via a pair of gears 7 19. The circular rod 17 drives the gear 6 18 to rotate. Since the gear 6 18 meshes with the annular rack 6 16, it drives the annular rack 6 16 to rotate. The annular rack 6 16 drives a set of sliding plates 20 and cleaning blocks 21 to rotate. Since the marine plastic pipe fittings need to be cleaned of residues after grinding and polishing, the rotation of the cleaning blocks 21 can clean the residues on the outer surface of the marine plastic pipe fittings, forming a continuous grinding and cleaning operation. This improves the overall processing smoothness of the grinding and polishing of marine plastic pipe fittings, increases the overall grinding and polishing efficiency, and makes it less likely for waste chips to affect the grinding of the positive annular grinding plate 6 and the reverse annular grinding plate 902.

[0024] Connecting posts 25 are fixedly connected to the bottom of the outer walls of both connecting plate 1 5 and connecting plate 2 901; a collection box 26 is fixedly connected to the bottom of the outer walls of a pair of connecting posts 25; the bottom of the outer wall of the collection box 26 is slidably connected to the top of the outer wall of the base 1; the collection box 26 is located below the positive annular grinding plate 6, the negative annular grinding plate 902 and the cleaning block 21. When connecting plate 1 5 and connecting plate 2 901 move, connecting plate 1 5 and connecting plate 2 901 drive the collection box 26 to move through the connecting posts 25, so that the collection box 26 is always located below the positive annular grinding plate 6, the negative annular grinding plate 902 and the cleaning block 21, thereby facilitating the collection of fallen or cleaned residues and avoiding pollution of the working environment by the residues.

[0025] One side of the outer wall of a set of cleaning blocks 21 is slidably connected to one side of the inner wall of a set of sliding plates 20; one side of the outer wall of each set of sliding plates 20 is rotatably connected to a reciprocating rod 22, and one end of the outer wall of each set of reciprocating rods 22 passes through a corresponding set of cleaning blocks 21; the set of reciprocating rods 22 and the set of corresponding cleaning blocks 21 are reciprocally connected; one end of the outer wall of each set of reciprocating rods 22 is fixedly connected to a gear 8 23; one side of the outer wall of the connecting plate 2 901 is fixedly connected to a ring rack 8 24 through a pair of auxiliary plates 8; the ring rack 8 24 meshes with a set of gears 8 23, when the sliding plate 2 When the cleaning block 21 rotates, the rotation of the slide plate 20 drives the reciprocating rod 22 and the gear 8 23 on the reciprocating rod 22 to rotate. Since the ring rack 8 24 meshes with a set of gears 8 23 and the ring rack 8 24 is in a fixed state, when the gear 8 23 rotates, the ring rack 8 24 rotates, thereby driving the reciprocating rod 22 to rotate. The rotation of the reciprocating rod 22 drives the cleaning block 21 to reciprocate. Thus, the cleaning block 21 rotates and reciprocates back and forth, wiping the surface of the marine plastic pipe fittings, thereby improving the cleaning effect of removing residues and making the cleaning effect better.

[0026] A stirring rod 27 is rotatably connected to the bottom of the inner wall of the collection box 26; a set of stirring plates 28 is fixedly connected to the outer wall of the stirring rod 27; a stirring gear 29 is fixedly connected to the top of the outer wall of the stirring plate 28; a stirring rack 30 is fixedly connected to one side of the outer wall of the fixed plate 201, and the stirring rack 30 meshes with the stirring rack 30. When the collection box 26 moves, the collection box 26 drives the stirring rod 27 and the stirring gear 29 on the stirring rod 27 to move. Because the stirring rack 30 meshes with the stirring rack 30, the stirring gear 29 rotates through the stirring rack 30 when it moves, thereby driving the stirring rod 27 and the stirring plate 28 to rotate, so that the stirring plate 28 stirs the residue collected in the collection box 26, avoiding the accumulation of residue, and allowing the residue to be evenly spread in the collection box 26, so that the collection box 26 can collect more residue.

[0027] Both the positive annular grinding plate 6 and the negative annular grinding plate 902 have a set of circular through grooves 10 on opposite ends of their outer walls; grinding columns 11 are rotatably connected to one end of the inner wall of each of the two sets of circular through grooves 10; gears 12 are fixedly connected to opposite ends of the outer walls of each of the two sets of grinding columns 11 via rotating rods 2; ring racks 15 are fixedly connected to opposite sides of the outer walls of connecting plate 1 and connecting plate 2 901 via auxiliary plate 13 and auxiliary plate 2 14 respectively; a pair of ring racks 15 mesh with the two sets of gears 12 respectively. When the positive annular grinding plate 6 and the negative annular grinding plate 902 rotate, the positive annular grinding plate 6... The reverse annular grinding plate 902 simultaneously drives the two sets of grinding columns 11 to rotate. The grinding columns 11 drive the gear 5 12 to rotate through the rotating rod 2. Since a pair of annular racks 2 15 mesh with the two sets of gears 5 12 respectively, and the annular racks 2 15 are in a fixed state, when the gears 5 12 rotate, they rotate through the annular racks 2 15, thereby driving the grinding columns 11 to rotate. The grinding columns 11 rotate along with the positive annular grinding plate 6 and the reverse annular grinding plate 902, thereby further improving the grinding effect of this application and further improving the overall grinding efficiency of this application.

[0028] Example 2:

[0029] Please see Figure 1 and Figures 8-9 As shown, a pair of inclined plates 31 are fixedly connected to the top of the outer wall of the collection box 26 via a pair of connecting plates 8, and the pair of inclined plates 31 are located on both sides of the positive annular grinding plate 6 and the negative annular grinding plate 902; a set of auxiliary rods 32 are rotatably connected to one side of the outer wall of each pair of inclined plates 31, and the bottom ends of the outer walls of the two sets of auxiliary rods 32 respectively penetrate the pair of inclined plates 31; gears 9 33 are fixedly connected to the top of the outer walls of the two sets of auxiliary rods 32; a set of fan blades 34 are fixedly connected to the outer walls of the two sets of auxiliary rods 32, and multiple sets of fan blades 34 are respectively matched with the positive annular grinding plate 6, the negative annular grinding plate 902 and the cleaning block 21; a pair of racks 9 35 are fixedly connected to the top of the outer wall of the base 1 via a pair of connecting plates 9; the pair of racks 9 35 mesh with the two sets of gears 9 33 respectively. When the collection box 26 moves, it drives a pair of inclined plates 31 to move via a pair of connecting plates 8. The inclined plates 31 drive the auxiliary rod 32 and the gear 9 33 on the auxiliary rod 32 to move. Since a pair of racks 9 35 mesh with the two sets of gears 9 33 respectively, when the gears 9 33 move, they rotate through the racks 9 35, thereby driving the auxiliary rod 32 and the fan blades 34 to rotate, causing the fan blades 34 to blow air and blow off the residue on the surface of the marine plastic pipe fittings. Since the inclined plates 31 are tilted, the air blows the residue into the collection box 26. This allows the air blower to work in conjunction with the positive ring grinding plate 6, the negative ring grinding plate 902 and the cleaning block 21 to improve the grinding and cleaning effect, thereby increasing the overall grinding and cleaning efficiency.

[0030] In use, the present invention involves fitting the marine plastic pipe fitting onto the support fixing rod 205 on the fixed plate 201, causing the support fixing rod 205 to engage with the inner wall of the marine plastic pipe fitting. Then, by rotating the threaded rod 202, the moving plate 203 is moved, causing the support fixing rod 205 on the moving plate 203 to engage with the inner wall of the marine plastic pipe fitting. At this time, a pair of circular columns 204 press against both sides of the marine plastic pipe fitting, which, together with the pair of support fixing rods 205, fixes the marine plastic pipe fitting.

[0031] Before fixing the marine plastic pipe fitting, the annular grinding plate 6 is fitted onto the marine plastic pipe fitting. The motor 3 drives the threaded shaft 4 to rotate. Because the threaded shaft 4 is threadedly connected to the connecting plate 5, the rotation of the threaded shaft 4 causes the connecting plate 5 and the annular grinding plate 6 to move. Simultaneously, the rotation of the threaded shaft 4 drives the gear 7 to rotate. Since gear 7 meshes with gear 8, gear 7 drives gear 8 to rotate, thereby driving the annular grinding plate 6 to rotate. This allows the annular grinding plate 6 to move and rotate while performing grinding. The reverse grinding mechanism 9 simultaneously grinds marine plastic pipe fittings, enabling the application to perform multi-directional cutting on the surface of marine plastic pipe fittings through cross-friction trajectories. This eliminates unidirectional scratches, reduces surface roughness, and reduces material accumulation. It solves the problem of burrs and cracks that are prone to occur in unidirectional grinding. Furthermore, multi-directional grinding can complete multi-directional processing in a single pass, thereby shortening grinding time, improving grinding efficiency and effect. In addition, multi-directional grinding provides uniform frictional heat distribution, reducing the risk of local overheating, eliminating the need for frequent shutdowns for cooling, and enhancing continuous operation capability.

[0032] When the positive annular grinding plate 6 rotates, it drives the gear 3 903 to rotate. Because the annular rack 1 905, gear 4 904 and gear 3 903 mesh with each other, gear 3 903 drives gear 4 904 to rotate, and gear 4 904 drives annular rack 1 905 to rotate. The rotation direction of annular rack 1 905 is opposite to that of gear 3 903. At this time, annular rack 1 905 drives the reverse annular grinding plate 902 to rotate through the annular block, so that the positive annular grinding plate 6 rotates in the forward direction for grinding, and the reverse annular grinding plate 902 rotates in the reverse direction for grinding, thus forming a relative rotational friction trajectory. This causes the contact points between the positive annular grinding plate 6, the reverse annular grinding plate 902 and the surface of the marine plastic pipe fitting to produce multi-directional and cross-cutting action, which solves the problem of uneven surface texture caused by grinding in a single direction. In addition, this application uses reverse friction to promote the shedding of debris, improve the material removal efficiency, and improve the surface smoothness of the marine plastic pipe fitting.

[0033] When the positive annular grinding plate 6 and the negative annular grinding plate 902 rotate, they simultaneously drive the two sets of grinding columns 11 to rotate. The grinding columns 11 drive the gear 5 12 to rotate through the rotating rod 2. Since a pair of annular racks 2 15 mesh with the two sets of gears 5 12 respectively, and the annular racks 2 15 are in a fixed state, when the gears 5 12 rotate, they rotate through the annular racks 2 15, thereby driving the grinding columns 11 to rotate. The grinding columns 11 rotate along with the positive annular grinding plate 6 and the negative annular grinding plate 902, thereby further improving the grinding effect of this application and further improving the overall grinding efficiency of this application.

[0034] When the reverse annular grinding plate 902 rotates, gears 19 are fixedly connected to the outer walls of both the reverse annular grinding plate 902 and the circular rod 17, and a pair of gears 19 mesh with each other. This causes the reverse annular grinding plate 902 to drive the circular rod 17 to rotate through the pair of gears 19. The circular rod 17 then drives gear 18 to rotate. Since gear 18 meshes with the annular rack 16, it drives the annular rack 16 to rotate. This causes the annular rack 16 to drive a set of sliding plates 20 and cleaning blocks 21 to rotate. Since marine plastic pipe fittings need to be cleaned of residue after grinding and polishing, the rotation of the cleaning blocks 21 can clean the residue on the outer surface of the marine plastic pipe fittings, forming a continuous grinding and cleaning operation. This improves the overall processing smoothness of the grinding and polishing of marine plastic pipe fittings, increases the overall grinding and polishing efficiency, and makes it less likely for waste chips to affect the grinding of the positive annular grinding plate 6 and the reverse annular grinding plate 902.

[0035] When the slide plate 20 and the cleaning block 21 rotate, the rotation of the slide plate 20 drives the reciprocating rod 22 and the gear 8 23 on the reciprocating rod 22 to rotate. Since the ring rack 8 24 meshes with a set of gears 8 23 and the ring rack 8 24 is in a fixed state, when the gear 8 23 rotates, the ring rack 8 24 rotates, thereby driving the reciprocating rod 22 to rotate. The rotation of the reciprocating rod 22 drives the cleaning block 21 to reciprocate. Thus, the cleaning block 21 rotates and reciprocates back and forth, wiping the surface of the marine plastic pipe fittings, thereby improving the cleaning effect of removing residues and making the cleaning effect better.

[0036] When connecting plate 5 and connecting plate 901 move, they drive the collection box 26 to move via connecting column 25, so that the collection box 26 is always located below the positive annular grinding plate 6, the negative annular grinding plate 902 and the cleaning block 21, which facilitates the collection of fallen or cleaned residues and avoids the residues from polluting the working environment.

[0037] When the collection box 26 moves, it drives the stirring rod 27 and the stirring gear 29 on the stirring rod 27 to move. Because the stirring rack 30 meshes with the stirring rack 30, the stirring gear 29 rotates through the stirring rack 30 when it moves, thereby driving the stirring rod 27 and the stirring plate 28 to rotate. This causes the stirring plate 28 to stir the residue collected in the collection box 26, preventing the residue from accumulating and allowing the residue to be evenly spread in the collection box 26, so that the collection box 26 can collect more residue.

[0038] When the collection box 26 moves, it drives a pair of inclined plates 31 to move via a pair of connecting plates 8. The inclined plates 31 drive the auxiliary rod 32 and the gear 9 33 on the auxiliary rod 32 to move. Since a pair of racks 9 35 mesh with the two sets of gears 9 33 respectively, the gears 9 33 rotate through the racks 9 35 when they move, thereby driving the auxiliary rod 32 and the fan blades 34 to rotate, causing the fan blades 34 to blow air and blow off the residue on the surface of the marine plastic pipe fittings. Since the inclined plates 31 are tilted, the air blows the residue into the collection box 26. This allows the air blower to work in conjunction with the positive ring grinding plate 6, the negative ring grinding plate 902 and the cleaning block 21, thereby improving the grinding and cleaning effect and increasing the overall grinding and cleaning efficiency.
