Description

Technical Field

[0001] This utility model relates to the field of combined refining mill roller technology, specifically to an assembly structure for a combined refining mill roller. Background Technology

[0002] A refining mill is a rubber mixing machine used to remove hard impurities from recycled rubber. The front and rear rollers have smooth surfaces and are roughly drum-shaped. During operation, the refining mill forces hard impurities from the rubber compound from the center of the rollers towards both ends, accumulating them on the edges of the rubber sheet. Then, a cutter removes the impurities from the rubber edges.

[0003] Existing refining mill rollers are often sealed with a single sealing ring after assembly. However, this single sealing method is difficult to withstand complex working conditions and is prone to seal failure. Seal failure will lead to leakage of coolant inside the roller, thereby reducing the refining effect and causing material pollution and waste. Utility Model Content

[0004] The purpose of this invention is to provide an assembly structure for a combined refining mill roller. By using this device, the problem of insufficient sealing of existing rollers after assembly is solved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for a combined refining mill roller, including a base plate and a bracket disposed on the upper surface of the base plate, wherein a roller is disposed on one side of the bracket, and a sealing component for increasing sealing is disposed inside the roller;

[0006] The sealing assembly includes a support plate disposed on the inner wall of the roller, an inner cylinder passing through the support plate, and a water pipe passing through the inner cylinder. A slot is provided on one side of the support plate, and a locking block is fitted inside the slot. A locking block is provided on one side of the locking block, and a sealing block passes through the locking block. The water pipe passes through the interior of the sealing block, and a cavity is formed between the roller and the inner cylinder. A water hole is provided on one side of the inner cylinder, and a one-way valve is provided on the inner wall of the inner cylinder. A return pipe is provided at one end of the one-way valve and is connected to the interior of the cavity.

[0007] Furthermore, the bracket is provided with a bearing seat A inside, and two sets of bearing seats A are symmetrically arranged. Each set of bearing seats A is provided with a mounting seat A inside, and the interior of each set of mounting seats A is connected to one end of the roller. A connecting shaft is provided on one side of each set of mounting seats A, and a motor is provided at one end of one set of the connecting shafts.

[0008] Furthermore, gears are fitted onto the outer surfaces of both sets of connecting shafts, and the two sets of gears mesh with each other.

[0009] Furthermore, a mounting frame is correspondingly provided on the upper surface of the base plate, and a bearing seat B is provided inside the mounting frame. Two sets of bearing seats B are symmetrically arranged, and a mounting seat B is provided inside each set of bearing seats B. The inner walls of the two sets of mounting seats B are respectively fitted and connected to one end of the two sets of rollers, and the inner wall of the mounting seat B is in contact with one side of the locking block.

[0010] Furthermore, a bidirectional rotary joint is provided through the center of each set of mounting bases B. One end of the bidirectional rotary joint is connected to the water pipe, and the outer surface of the bidirectional rotary joint is in contact with the inside of the sealing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention proposes an assembly structure for a combined refining mill roller. Existing technologies often suffer from insufficient sealing after roller assembly. This invention, through a locking block, slot, support plate, sealing block, and locking block, allows cold water to flow into the roller through a water pipe when cooling is needed. The water then enters the cavity through water holes, circulates within the cavity, and absorbs heat from the roller. Some of the fluid can then flow back through a return pipe connected to the inside of the cavity, creating a circulation loop. Simultaneously, a sealing block between the water pipe and the inner cylinder prevents coolant overflow. The locking block is then fitted into a slot on one side of the support plate, and a locking block on one side restricts the movement of the sealing block, increasing sealing performance and effectively preventing fluid leakage inside the roller.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figure 1 and Figure 2 An assembly structure for a combined refining mill roller includes a base plate 1 and a support 2 disposed on the upper surface of the base plate 1. A roller 3 is disposed on one side of the support 2, and a sealing component 4 for increasing sealing is disposed inside the roller 3.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figures 1-4 The sealing assembly 4 includes a support plate 41 disposed on the inner wall of the roller 3, an inner cylinder 42 passing through the support plate 41, and a water pipe 43 passing through the inner cylinder 42. A slot 44 is provided on one side of the support plate 41, and a locking block 45 is fitted inside the slot 44. A locking block 46 is provided on one side of the locking block 45, and a sealing block 47 passes through the locking block 46. The water pipe 43 passes through the interior of the sealing block 47. A cavity 48 is formed between the roller 3 and the inner cylinder 42. A water hole 421 is provided on one side of the inner cylinder 42. A one-way valve 49 is provided on the inner wall of the inner cylinder 42. A return pipe 491 is provided at one end of the one-way valve 49. The return pipe 491 is connected to the interior of the cavity 48, effectively preventing the leakage of coolant inside the roller 3.

[0024] The bracket 2 has a bearing seat A5 inside, and two sets of bearing seats A5 are symmetrically arranged. Each set of bearing seats A5 has a mounting seat A51 inside, and the interior of each set of mounting seats A51 is connected to one end of the roller 3. A connecting shaft 52 is provided on one side of each set of mounting seats A51. One end of one set of connecting shafts 52 is provided with a motor 53. The two sets of rollers 3 are installed into the corresponding bearing seats A5 through the two sets of mounting seats A51, which facilitates the assembly of the rollers 3.

[0025] Gears 54 are fitted on the outer surfaces of both sets of connecting shafts 52. The two sets of gears 54 mesh with each other. By rotating the two sets of gears 54, the two sets of rollers 3 are ensured to rotate synchronously and in opposite directions, so that the material is subjected to uniform force and the refining effect is improved.

[0026] A mounting bracket 6 is provided on the upper surface of the base plate 1. A bearing seat B61 is provided inside the mounting bracket 6. Two sets of bearing seats B61 are symmetrically arranged. Each set of bearing seats B61 has a mounting seat B62 inside. The inner walls of the two sets of mounting seats B62 are respectively fitted and connected to one end of the two sets of rollers 3. The inner walls of the mounting seats B62 are in contact with one side of the locking block 46. One end of the roller 3 is installed into the bearing seat B61 located inside the mounting bracket 6 through the mounting seat B62, so as not to affect the rotation of the roller 3. At the same time, the mounting seat B62 is in contact with one side of the locking block 46, which can further restrict the position of the locking block 46, thereby preventing liquid leakage.

[0027] Each mounting base B62 has a bidirectional rotary joint 7 running through its center. One end of the bidirectional rotary joint 7 is connected to the water pipe 43, and the outer surface of the bidirectional rotary joint 7 is in contact with the inside of the sealing block 47. The other end of the bidirectional rotary joint 7 is connected to the liquid supply assembly, ensuring that during the rotation of the roller 3, the liquid can smoothly enter the water pipe 43 inside the roller 3 from the liquid supply assembly. At the same time, the outer surface of the bidirectional rotary joint 7 is in contact with the inside of the sealing block 47, ensuring that the liquid will not leak at the bidirectional rotary joint 7.

[0028] Each mounting bracket A51 and mounting bracket B62 has a sealing gasket 8 on its inner wall to further prevent coolant leakage.

[0029] Specifically, first, the inner cylinder 42 is installed inside the roller 3 via the support plate 41. Then, the water pipe 43 is inserted into the inner cylinder 42. Since a sealing block 47 is provided between the water pipe 43 and the inner cylinder 42, the coolant in the inner cylinder 42 is prevented from overflowing. Then, the locking block 45 is fitted into the slot 44 on one side of the support plate 41, and a locking block 46 is provided on one side of the locking block 45. The movement of the sealing block 47 can be restricted by the locking block 46, thereby increasing the sealing performance. Then, one end of each of the two sets of rollers 3 is installed into the corresponding bearing seats A5 via two sets of mounting bases A51, thereby facilitating the roller... The assembly of roller 3 involves connecting shafts 52 on one side of both sets of mounting bases A51, with two sets of meshing gears 54 fitted on the outer surfaces of the connecting shafts 52. After subsequent installation, the rollers 3 can be started by motor 53, ensuring synchronous and counter-rotating rotation. This ensures the material receives uniform force, improving refining efficiency. Beforehand, the other ends of the two rollers 3 need to be installed into bearing seats B61 inside the mounting frame 6 via mounting base B62, without affecting the rotation of the rollers 3. Simultaneously, mounting base B62 contacts one side of locking block 46. This further restricts the position of the locking block 46, thus preventing liquid leakage. Since one end of the water pipe 43 is connected to one end of the bidirectional rotary joint 7, and the outer surface of the bidirectional rotary joint 7 contacts the interior of the sealing block 47, it ensures that during the rotation of the roller 3, liquid can smoothly enter the water pipe 43 inside the roller 3 from the liquid supply assembly. Simultaneously, the contact between the outer surface of the bidirectional rotary joint 7 and the interior of the sealing block 47 ensures that liquid will not leak at the bidirectional rotary joint 7. Furthermore, since the other end of the bidirectional rotary joint 7 is connected to the liquid supply assembly, therefore... When cooling roller 3 is required, liquid starts from the liquid supply assembly, enters the water pipe 43 through the bidirectional rotary joint 7 that runs through the center of the mounting base B62, and then is injected into the inner cylinder 42 through the water pipe 43. It then enters the cavity 48 through the water hole 421 at the bottom of the inner cylinder 42, and then returns to the inner cylinder 42 through the return pipe 491 located in the cavity 48. At the same time, since a one-way valve 49 is provided between the return pipe 491 and the inner cylinder 42, and the direction of this one-way valve 49 is from the cavity 48 to the inner cylinder 42, it is ensured that the cooled liquid can smoothly return to the inner cylinder 42 without backflow.
