Description

Technical Field

[0001] This utility model relates to the field of roller core processing technology, specifically a support device for roller core processing. Background Technology

[0002] Rubber rollers are roller-shaped products made by vulcanizing rubber with a metal or other material core. Their processing includes core sandblasting, bonding, rubber forming, fabric wrapping, wire winding, vulcanization in a vulcanizing tank, and surface finishing. Rubber rollers are mainly used in papermaking, dyeing, printing, grain processing, metallurgy, and plastics processing.

[0003] Roll cores are usually machined on a lathe. When machining some long roll cores on a lathe, one end of the roll core is fixed on the chuck. Because the roll core is long, the end will vibrate and become unstable during rotation. Therefore, a support device for roll core machining is needed to support the roll core and ensure that the position of the roll core is stable during the machining process.

[0004] However, in existing support devices for roller core processing, the surface of the roller core blank and the support roller of the support device are in direct contact when facing the roller core blank. This leads to accelerated wear of the support roller and the roller core surface, thereby reducing the precision of the roller core and shortening the service life of the support roller. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a support device for roller core processing, which solves the problem that when existing roller core processing support devices face roller core blanks, the surface of the roller core blank and the support roller of the support device directly contact each other, resulting in accelerated wear of the support roller and roller core surface, thereby reducing the precision of the roller core and shortening the service life of the support roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support device for roller core processing, comprising a first housing, with support rollers arranged on the upper sides of both sides of the first housing, and a lubrication device arranged below the two support rollers. The lubrication device includes a support base, a second housing, a first rotating roller, baffles, and a discharge valve. The support base is rotatably connected to the outer wall of the support rollers via pins. The second housing is fixedly connected to the side of the two support bases that are far apart from each other. The inner wall of the second housing is rotatably connected to the first rotating roller via pins on the side close to the support bases. The top of the first rotating roller is attached to the bottom of the outer wall of the support rollers. Baffles are fixedly connected to the top of the inner wall of the second housing on both sides of the first rotating roller. The bottom of the second housing is connected to the discharge valve.

[0007] Preferably, an oil replenishment device is provided on the side of the second housing away from the support base. The oil replenishment device includes a first connecting pipe, an oil storage tank, a refueling pipe, a suspension cylinder, a telescopic pipe, and a second connecting pipe. The first connecting pipe is connected to the top of the second housing on the side away from the support base. The other end of the first connecting pipe is connected to a telescopic pipe. The other end of the telescopic pipe is connected to the second connecting pipe. The other end of the second connecting pipe is connected to the oil storage tank. The bottom of the oil storage tank is fixedly connected to the top of the first housing. The refueling pipe is connected to the side of the outer wall of the oil storage tank away from the telescopic pipe. A suspension cylinder is inserted into the inner wall of the end of the first connecting pipe that extends into the interior of the second housing.

[0008] Preferably, a threaded block is fixedly connected to the bottom of the support base, the bottom of the threaded block is slidably engaged with the bottom inner wall of the first housing, a double-ended threaded rod is threadedly connected to the inner wall of the threaded block, the two ends of the double-ended threaded rod are respectively rotatably connected to the two sides of the first housing through pins, and a handle is fixedly connected to one end of the double-ended threaded rod extending to the outside of the first housing.

[0009] Preferably, a first column is fixedly connected to the bottom of the inner wall of the first box between the two support seats. A first sleeve is sleeved on the outer wall of the first column. A spring is fixedly connected to the top of the inner wall of the first sleeve. The other end of the spring is fixedly connected to the top of the first column. A second rotating roller is rotatably connected to both sides of the top of the first sleeve through a pin.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the bottom of the first housing, and a support plate is fixedly connected to the bottom of the hydraulic cylinder.

[0011] Preferably, a second sleeve is fixedly connected to each of the four top corners of the support plate, a second column is inserted into the inner wall of the second sleeve, and the top of the second column is fixedly connected to the four bottom corners of the first box.

[0012] This utility model has the following beneficial effects: The support device for roller core processing, through the cooperation between the support base, the second housing, the first rotating roller, the baffle, and the discharge valve, achieves the effect of the existing support device for roller core processing, where the first rotating roller drives the lubricating oil inside the second housing to be applied to the surface of the support roller when facing the roller core blank, thereby reducing the friction between the support roller and the roller core blank. This solves the problem that in the existing support device for roller core processing, the surface of the roller core blank and the support roller of the support device are in direct contact when facing the roller core blank, which leads to accelerated wear of the support roller and the surface of the roller core, thereby reducing the precision of the roller core and shortening the service life of the support roller.

[0013] By coordinating the telescopic pipe, oil storage tank, refueling pipe, suspension cylinder, first connecting pipe, second connecting pipe, and second connecting rod, the existing roller core processing support device achieves the effect of automatically replenishing the lubricating oil inside the second housing with the lubricating oil in the oil storage tank through the connecting pipe when the existing roller core processing support device is short of oil. This solves the problem that the existing roller core processing support device requires operators to manually brush oil between the support roller and the roller core, resulting in uneven coating and low efficiency of manual coating.

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

[0022] In existing support devices for roller core processing, the surface of the roller core blank and the support roller of the support device are in direct contact when facing the roller core blank. This leads to accelerated wear of the support roller and the roller core surface, thereby reducing the precision of the roller core and shortening the service life of the support roller.

[0023] In view of this, the present invention provides a support device for roller core processing. This support device, through the cooperation of a support base, a second housing, a first rotating roller, a baffle, and a discharge valve, achieves the effect of reducing friction between the support roller and the roller core blank when the existing roller core processing support device faces the roller core blank. Specifically, the first rotating roller drives the lubricating oil inside the second housing to be applied to the surface of the support roller, thus reducing the friction between the support roller and the roller core blank. This solves the problem that in existing roller core processing support devices, the surface of the roller core blank and the support roller of the support device directly contact each other when facing the roller core blank, leading to accelerated wear of both surfaces, reduced roller core precision, and shortened service life of the support roller.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0025] Example 1, by Figure 1-6As can be seen, the support device for processing roller cores in this case includes a first housing 1. Support rollers 2 are arranged on the upper sides of both sides of the first housing 1, supporting the roller core. A lubrication device is arranged below the two support rollers 2 to reduce the friction between the support rollers 2 and the roller core. The lubrication device includes a support base 13, a second housing 3, a first rotating roller 4, a baffle 5, and a discharge valve 6. The support base 13 is rotatably connected to the outer wall of the support roller 2 via a pin, supporting the support roller 2. The second housing 3 is fixedly connected to the outer wall of the two support bases 13 on opposite sides. The second housing 3 is filled with lubricating oil. The inner wall of the second housing 3, near the support base 13, is rotatably connected to the first rotating roller 4 via a pin. A brush is fixedly connected to the outer wall of the first rotating roller 4, the brush being dipped in lubricating oil. The top of the first rotating roller 4 is in contact with the bottom of the outer wall of the support roller 2. The first rotating roller 4 has baffles 5 fixedly connected to the top of the inner wall of the second housing 3 on both sides. The baffles 5 squeeze off the excess lubricating oil on the surface of the first rotating roller 4 to prevent excessive lubricating oil on the surface of the support roller 2. The bottom of the second housing 3 is connected to a drain valve 6. When the lubricating oil inside the second housing 3 has been used for a long time, the lubricating oil inside the second housing 3 is drained out through the drain valve 6. When the support device for roller core processing is used, the roller core drives the support roller 2 to rotate by friction. The support roller 2 drives the first rotating roller 4 to rotate. The first rotating roller 4 picks up the lubricating oil inside the second housing 3 and applies it to the surface of the support roller 2. The lubricating oil forms an oil film between the roller core and the support roller 2, which reduces the friction coefficient between the two. However, due to the large mass of the roller core itself, the friction will not completely disappear. When the roller core rotates, it will still drive the support roller 2 to rotate through the remaining friction.

[0026] In the specific implementation process, it is worth noting that the support roller 2 supports the roller core, and the friction between the support roller 2 and the roller core is reduced by the lubrication device. The support seat 13 supports the support roller 2. The second box 3 is filled with lubricating oil. A brush is fixedly connected to the outer wall of the first rotating roller 4 to pick up the lubricating oil. The baffle 5 squeezes off the excess lubricating oil on the surface of the first rotating roller 4 to prevent excessive lubricating oil on the surface of the support roller 2. When the lubricating oil in the second box 3 has been used for a long time, it is discharged through the discharge valve 6. When the support device for roller core processing is used, the roller core drives the support roller 2 to rotate by friction. The support roller 2 drives the first rotating roller 4 to rotate. The first rotating roller 4 picks up the lubricating oil in the second box 3 and applies it to the surface of the support roller 2, thus achieving the application of lubricating oil to the support roller 2.

[0027] Furthermore, an oil replenishment device is provided on the side of the second housing 3 away from the support base 13. The oil replenishment device includes a first connecting pipe 11, an oil storage tank 8, a refueling pipe 9, a suspension cylinder 10, a telescopic pipe 7, and a second connecting pipe 12. The first connecting pipe 11 is connected to the top of the second housing 3 on the side away from the support base 13. The other end of the first connecting pipe 11 is connected to the telescopic pipe 7, the other end of the telescopic pipe 7 is connected to the second connecting pipe 12, and the other end of the second connecting pipe 12 is connected to the oil storage tank 8. When the support base 13 moves, the telescopic pipe 7 extends and retracts. The oil storage tank 8 contains lubricating oil. The lubricating oil, under the influence of gravity, enters the telescopic pipe 7 through the second connecting pipe 12, and then enters the second housing 3 through the first connecting pipe 11 to replenish the oil in the second housing 3. The bottom of the oil storage tank 8 is fixedly connected to... The first box 1 is attached to the top of the first box 1 and supports the oil storage tank 8. The side of the outer wall of the oil storage tank 8 away from the telescopic pipe 7 is connected to the oil filling pipe 9. When the oil storage tank 8 is not enough, the oil storage tank 8 is replenished through the oil filling pipe 9. The first connecting pipe 11 is connected to the inner wall of the second box 3 and a suspension cylinder 10 is inserted. The suspension cylinder 10 is made of plastic and is lightweight and can float in water. The top of the suspension cylinder 10 is hollow and the side wall is provided with several connection holes. When the oil level in the second box 3 is not enough, the liquid level drops and the suspension cylinder 10 moves to the surface and leaves the inner wall of the telescopic pipe 7 through the connection holes. The lubricating oil inside the telescopic pipe 7 flows into the interior of the second box 3 through the connection holes. After that, the suspension cylinder 10 returns to the initial position due to buoyancy.

[0028] In the specific implementation process, it is worth noting that when the support base 13 moves, the telescopic tube 7 extends and retracts. The oil tank 8 is filled with lubricating oil. Under the influence of gravity, the lubricating oil enters the telescopic tube 7 through the second connecting tube 12, and then enters the second box 3 through the first connecting tube 11 to replenish the oil in the second box 3. The first box 1 supports the oil tank 8. When the lubricating oil in the oil tank 8 is insufficient, the oil tank 8 is replenished through the oil filling pipe 9. The suspension cylinder 10 is made of plastic, which is lightweight and can float in water. The top of the suspension cylinder 10 is hollow, and several connection holes are opened on the side wall. When the lubricating oil in the second box 3 is insufficient, the liquid surface drives the suspension cylinder 10 to move until the surface connection holes leave the inner wall of the telescopic tube 7. The lubricating oil in the oil tank 8 flows into the interior of the second box 3 through the connection holes. After completion, the suspension cylinder 10 returns to the initial position under the influence of the buoyancy of the liquid surface, thus realizing the replenishment of oil in the second box 3.

[0029] Furthermore, a threaded block 14 is fixedly connected to the bottom of the support base 13. The bottom of the threaded block 14 is slidably engaged with the bottom inner wall of the first housing 1. A double-ended threaded rod 15 is threadedly connected to the inner wall of the threaded block 14. The two ends of the double-ended threaded rod 15 are rotatably connected to the two sides of the first housing 1 through pins. The double-ended threaded rod 15 rotates on the inner wall of the first housing 1. A handle 16 is fixedly connected to one end of the double-ended threaded rod 15 extending to the outside of the first housing 1. When the diameter of the roller core is small, the operator drives the double-ended threaded rod 15 to rotate through the handle 16. The double-ended threaded rod 15 drives the threaded block 14 to move closer to each other, thereby driving the support base 13 to move. The support base 13 drives the support roller 2 to move to fit with the roller core. The support base 13 supports the roller core.

[0030] In the specific implementation process, it is worth noting that when the diameter of the roller core is small, the operator drives the double-headed threaded rod 15 to rotate on the inner wall of the first housing 1 through the handle 16. The double-headed threaded rod 15 drives the threaded block 14 to move towards each other, thereby driving the support seat 13 to move. The support seat 13 drives the support roller 2 to move to fit with the roller core. The support roller 2 supports the roller core, thus realizing the driving of the support roller 2.

[0031] Specifically, when the diameter of the roller core is small, the operator drives the double-ended threaded rod 15 to rotate through the handle 16. The double-ended threaded rod 15 drives the threaded block 14 to move closer to each other, which in turn drives the support seat 13 to move. The support seat 13 drives the support roller 2 to move to fit with the roller core. The support roller 2 supports the roller core, and the roller core drives the support roller 2 to rotate. The support roller 2 drives the first rotating roller 4 to rotate. The first rotating roller 4 dips into the lubricating oil inside the first housing 1 and applies it to the surface of the support roller 2. The lubricating oil reduces the friction between the support roller 2 and the roller core. When the lubricating oil inside the second housing 3 is insufficient, the liquid level drives the first suspension cylinder 10 to move until the surface connection hole leaves the inner wall of the telescopic tube 7. The lubricating oil inside the telescopic tube 7 flows into the interior of the first housing 1 through the connection hole. After completion, the suspension cylinder 10 returns to its initial position due to buoyancy.

[0032] Example 2, by Figure 1-6It can be seen that a first column 17 is fixedly connected to the bottom of the inner wall of the first housing 1 between the two support seats 13. A first sleeve 18 is sleeved on the outer wall of the first column 17. A threaded hole is opened on one side of the first sleeve 18, and a bolt is threaded into the inner wall of the threaded hole. A spring 19 is fixedly connected to the top of the inner wall of the first sleeve 18. The material of the spring 19 is carbon spring steel, and the elastic coefficient of the spring 19 is selected according to actual needs to meet the working requirements. The other end of the spring 19 is fixedly connected to the top of the first column 17. Both sides of the top of the first sleeve 18 are rotated by pins. The first sleeve 18 drives the second rotating roller 20 to move. The second rotating roller 20 converts the sliding friction between the roller core and the first sleeve 18 into rolling friction. When the diameter of the roller core is large, the operator first rotates the bolt away from the surface of the first column 17. The spring 19 undergoes elastic deformation and extends, thereby driving the first sleeve 18 to move upward until the second rotating roller 20 is in contact with the roller core. After completion, the operator rotates the bolt to the surface of the first column 17 to fix the first column 17. The second rotating roller 20 supports the roller core.

[0033] In the specific implementation process, it is worth noting that the side wall of the first sleeve 18 is provided with a threaded hole, and the inner wall of the threaded hole is connected with a bolt. The first sleeve 18 drives the second rotating roller 20 to move. The second rotating roller 20 converts the sliding friction between the roller core and the first sleeve 18 into rolling friction. When the diameter of the roller core is large, the operator first rotates the bolt away from the surface of the first column 17. The spring 19 undergoes elastic deformation and extends, thereby driving the first sleeve 18 to move upward until the second rotating roller 20 is in contact with the roller core. After completion, the operator rotates the bolt to the surface of the first column 17 to fix the first column 17. The second rotating roller 20 supports the roller core, thereby achieving further support for the roller core.

[0034] Furthermore, a hydraulic cylinder 21 is fixedly connected to the bottom of the first housing 1. The model of the hydraulic cylinder 21 is selected according to actual needs, as long as it meets the working requirements. The hydraulic cylinder 21 drives the first housing 1 to move. A support plate 24 is fixedly connected to the bottom of the hydraulic cylinder 21, and the support plate 24 supports the hydraulic cylinder 21.

[0035] In the specific implementation process, it is worth noting that the hydraulic cylinder 21 drives the first box 1 to move, and the support plate 24 supports the hydraulic cylinder 21, thereby realizing the lifting and lowering of the first box 1.

[0036] Furthermore, a second sleeve 23 is fixedly connected to each of the four top corners of the support plate 24. A second column 22 is inserted into the inner wall of the second sleeve 23. The second column 22 moves within the inner wall of the second sleeve 23. The top of the second column 22 is fixedly connected to the four bottom corners of the first box 1. The first box 1 drives the second column 22 to move. The second column 22 and the second sleeve 23 support the first box 1.

[0037] In the specific implementation process, it is worth noting that the second column 22 moves on the inner wall of the second sleeve 23, the first box 1 drives the second column 22 to move, and the second column 22 and the second sleeve 23 support the first box 1, thereby achieving the limitation of the first box 1.

[0038] Specifically, a threaded hole is provided on one side of the first sleeve 18, and a bolt is threaded onto the inner wall of the threaded hole. When the diameter of the roller core is large, the operator first rotates the bolt away from the surface of the first column 17. The spring 19 undergoes elastic deformation and extends, thereby driving the first sleeve 18 to move upward until the second rotating roller 20 is in contact with the roller core. After completion, the operator rotates the bolt to be in contact with the surface of the first column 17, fixing the first column 17. The second rotating roller 20 supports the roller core. The hydraulic cylinder 21 drives the first housing 1 to move. At this time, the second column 22 moves on the inner wall of the second sleeve 23. The first housing 1 drives the second column 22 to move. The second column 22 and the second sleeve 23 support the first housing 1. The support plate 24 supports the hydraulic cylinder 21.
