Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of open mill roller equipment, in particular to an internally cooled open mill roller. Background Art
[0002] The mixing mill is mainly used for rubber plasticization, and the processing temperature is low. The temperature control of the mixing mill roller is simple and rough, and the rubber temperature is mainly reduced by heat conduction. Due to the low flow rate of the circulating water, the thermal conductivity of the rubber itself is poor, and the scum on the inner surface of the roller sharply reduces the thermal conductivity, making it difficult to reduce the rubber temperature. In the prior art, when installing the water pipe joint of the cooling water guide pipe structure in the mixing mill roller, it is not easy to dock the two water pipes, and the docking of the water pipes is easy to shift, which affects the sealing of the joint and easily causes leakage. For this reason, we propose an internally cooled mixing mill roller. Utility Model Content
[0003] The utility model aims to provide an internally cooled mixing mill roller to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above object, the utility model provides the following technical solution: an internally cooled open mill roller, comprising a roller body, a cooling pipe is arranged inside the roller body, both ends of the cooling pipe are respectively connected to connecting pipes, and a sealing mechanism is arranged on the outside of the connection between the cooling pipe and the connecting pipe;
[0005] The sealing mechanism includes a sealing member, a sealing groove is provided on the inner side of the sealing member, a clamp is provided on the outer side of the sealing member, a connecting member is provided at the edge of the clamp, one end of the connecting pipe is connected to a connecting flange, and the other end of the connecting flange is connected to the water tank through a water inlet pipe.
[0006] In the above solution, a rubber ring is provided between the cooling pipe and the connecting pipe.
[0007] In the above solution, the sealing member is a cylindrical nitrile rubber sleeve structure, and the sealing member is clamped in the groove on the inner side of the clamp.
[0008] In the above solution, adjacent connecting members are connected by bolt assemblies.
[0009] In the above solution, the side walls of the cooling pipe and the connecting pipe are also provided with auxiliary water channels that are interconnected.
[0010] In the above solution, the end of the other connecting pipe is connected to a drainage mechanism.
[0011] In the above solution, the outer diameters of the cooling pipe and the connecting pipe are the same.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the internally cooled mixing mill roller has a simple and reasonable structural design and strong practicality. A cooling pipe is arranged inside the roller body, and the cooling pipe is connected to the connecting pipe accordingly. Through the cooperation of the water inlet pipe and the water tank, the purpose of cooling the mixing mill roller body can be achieved by introducing cold water into the connecting pipe and the cooling pipe, thereby ensuring the processing quality. A sealing mechanism formed by a sealing member and a clamp mechanism is arranged outside the interface between the cooling pipe and the connecting pipe, thereby forming a double sealing mechanism. If water leakage occurs at the interface, water reaches and fills the sealing groove under the action of pressure. By utilizing the special structure of the seal, the outer wall of the seal can be tightly attached to the inner wall of the clamp under the action of water flow pressure. The seal and the clamp are used in cooperation to form a two-way sealing mechanism, thereby improving the sealing effect of the water pipe joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 The utility model provides a technical solution: an internally cooled open mill roller, comprising a roller body 1, a cooling pipe 11 is arranged inside the roller body 1, both ends of the cooling pipe 11 are respectively connected to connecting pipes 12, and a sealing mechanism is arranged outside the connection between the cooling pipe 11 and the connecting pipe 12;
[0019] The sealing mechanism includes a sealing member 13, a sealing groove 14 is formed on the inner side of the sealing member 13, a clamp 15 is formed on the outer side of the sealing member 13, and a connector 17 is formed at the edge of the clamp 15. By arranging the sealing member 13 and the clamp 15 on the outside of the interface between the cooling pipe 11 and the connecting pipe 12, a double sealing mechanism can be formed. If water leakage occurs at the interface, water reaches and fills the sealing groove 14 under the action of pressure. By utilizing the special structure of the sealing member 13, the outer wall of the sealing member 13 can be tightly attached to the inner wall of the clamp 15 under the action of water flow pressure. The sealing member 13 and the clamp 15 are used in combination to form a two-way sealing mechanism, thereby improving the sealing effect of the water pipe joint.
[0020] One end of the connecting pipe 12 is connected to a connecting flange 19 , and the other end of the connecting flange 19 is connected to a water tank 21 through a water inlet pipe 2 .
[0021] By arranging a cooling pipe 11 inside the roller body 1 and correspondingly connecting the cooling pipe 11 with the connecting pipe 12, and cooperating with the water inlet pipe 2 and the water tank 21, the purpose of cooling the roller body of the mixing mill can be achieved by passing cold water into the connecting pipe 12 and the cooling pipe 11, thereby ensuring the processing and molding quality.
[0022] In the above solution, a rubber ring is provided between the cooling pipe 11 and the connecting pipe 12. The rubber ring is provided at the joint of the ends of the two, which can protect and fix the joint to avoid leakage, and further improve the sealing and leakproof effect.
[0023] In the above solution, the sealing member 13 is a cylindrical nitrile rubber sleeve structure, and the sealing member 13 is clamped in the groove 16 on the inner side of the clamp 15 .
[0024] In the above solution, adjacent connecting members 17 are connected by bolt assemblies 18. The clamp 15 is fixedly connected by the bolt assemblies 18, so that the clamp 15 effectively fixes and protects the seal 13 from the outside, thereby further improving the anti-leakage effect.
[0025] In the above scheme, the side walls of the cooling pipe 11 and the connecting pipe 12 are further provided with auxiliary water channels 22 that are interconnected. When the cooling pipe 11 and the connecting pipe 12 are connected to each other, the corresponding auxiliary water channels 22 are interconnected, and water or cold air is added to the auxiliary water channels 22, thereby cooperating with the inner cavities of the cooling pipe 11 and the connecting pipe 12 to achieve the purpose of auxiliary cooling.
[0026] In the above solution, a drainage mechanism is connected to the end of the other connecting pipe 12. Water flows into the connecting pipe 12 and the cooling pipe 11 through the water inlet pipe 2, taking away the heat of the roller body 1 in the process, and the waste water is discharged into the drainage mechanism through the other connecting pipe 12.
[0027] In the above solution, the outer diameters of the cooling pipe 11 and the connecting pipe 12 are the same.
[0028] Working principle:
[0029] When this type of internally cooled mixing mill roller is used, a cooling pipe 11 is arranged inside the roller body 1, and a connecting pipe 12 is connected to the end of the cooling pipe 11. The connecting pipe 12 is connected to the water pump in the water tank 21 through the connecting flange 19 and the water inlet pipe 2. During operation, cold water in the water tank 21 flows into the cooling pipe 11 through the connecting pipe 12, and in this process, the heat of the roller body 1 is taken away, and the waste water is discharged into the drainage mechanism through another connecting pipe 12. When water leakage occurs at the connection between the connecting pipe 12 and the cooling pipe 11, water reaches and fills the sealing groove 14 under the action of pressure. By utilizing the special structure of the sealing member 13, the outer wall of the sealing member 13 can be tightly attached to the inner wall of the clamp 15 under the action of water flow pressure, and the sealing member 13 and the clamp 15 are used in combination to form a two-way sealing mechanism, thereby improving the sealing effect of the water pipe joint.
