Description

Technical Field

[0001] This utility model belongs to the field of internal mixer technology, specifically relating to a hybrid structure of a combined internal mixer. Background Technology

[0002] Internal mixers are mainly used for plasticizing and mixing rubber. They are machines that use a mixing structure with a specific shape and relative rotation to plasticize and mix polymer materials in a closed state with adjustable temperature and pressure.

[0003] In existing combined internal mixers, the mixing structure rotates under external force during use. Since the two ends of the mixing mechanism are in contact with the inner wall of the main body of the internal mixer, wear occurs between the ends of the mixing mechanism and the inner wall of the main body of the internal mixer during the rotation process. Therefore, this utility model proposes a mixing structure for combined internal mixers. Utility Model Content

[0004] The purpose of this utility model is to provide a hybrid structure for a combined internal mixer to solve the problem of insufficient protection in the hybrid structure of the combined internal mixer mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing structure for a combined internal mixer, comprising mixing mechanisms symmetrically arranged inside the main body of the internal mixer, wherein wear-resistant mechanisms are provided at both ends of the mixing mechanism and at the connection points between the mixing mechanism and the inner walls of the main body of the internal mixer, the wear-resistant mechanism being composed of a limiting rotation groove, a limiting rotation block, and a sliding component, wherein the limiting rotation groove is opened on the inner wall of the main body of the internal mixer, the limiting rotation block is disposed at the end of the mixing mechanism, and the sliding component is disposed on the inner side of the limiting rotation groove and at the end of the limiting rotation block.

[0006] Preferably, the cross-section of the limiting rotating block is circular, and the cross-section of the limiting rotating groove is also circular.

[0007] Preferably, the height of the limiting rotating block is smaller than the depth of the limiting rotating groove.

[0008] Preferably, the sliding component consists of multiple rolling components and rolling grooves, the rolling grooves being formed at the end of the limiting rotating block, and the multiple rolling components being disposed inside the limiting rotating grooves.

[0009] Preferably, the rolling assembly consists of balls and a groove, the groove being formed at the bottom end of the limiting rotation groove, and the balls being disposed inside the groove.

[0010] Preferably, the ball has a spherical structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By designing a wear-resistant mechanism, the original internal mixer's mixing mechanism was in a close fit with the inner wall of the main body during operation, causing wear at the contact point when the mixing mechanism rotated. By installing a wear-resistant mechanism between the end of the mixing mechanism and the inner wall of the main body, a certain gap is created between the end of the mixing mechanism and the inner wall of the main body without affecting the use, thus avoiding wear during operation and increasing the protection of the internal mixer during use.

[0017] 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.

[0018] Please see Figures 1 to 3This utility model provides a technical solution: a mixing structure for a combined internal mixer, including mixing mechanisms 2 symmetrically arranged inside the internal mixer body 1. The mixing mechanisms 2 and the internal mixer body 1 are a combined structure. Wear-resistant mechanisms 3 are provided at both ends of the mixing mechanism 2 and the inner walls of the internal mixer body 1. The wear-resistant mechanisms 3 consist of a limiting rotation groove 31, a limiting rotation block 32, and a sliding component 33. The wear-resistant mechanisms 3 create a certain gap at the contact point between the mixing mechanism 2 and the inner wall of the internal mixer body 1, increasing wear resistance. The limiting rotation groove 31 is opened on the inner wall of the internal mixer body 1, the limiting rotation block 32 is located at the end of the mixing mechanism 2, and the sliding components 33 are all located inside the limiting rotation groove 31. The end of the limiting rotating block 32 is equipped with a wear-resistant mechanism 3 to improve the original internal mixer operation process. In the case of the mixing mechanism 2 being in close contact with the inner wall of the internal mixer body 1, the mixing mechanism 2 would wear out at the contact point with the internal mixer body 1 when rotating. By setting the wear-resistant mechanism 3 between the end of the mixing mechanism 2 and the inner wall of the internal mixer body 1, a certain gap is created between the end of the mixing mechanism 2 and the inner wall of the internal mixer body 1 without affecting the use, thus avoiding wear during operation and increasing the protection of the internal mixer during use. The cross-section of the limiting rotating block 32 is circular, and the cross-section of the limiting rotating groove 31 is also circular. The height of the limiting rotating block 32 is smaller than the depth of the limiting rotating groove 31.

[0019] In this embodiment, preferably, the sliding component 33 is composed of multiple rolling components 331 and rolling grooves 332. The rolling grooves 332 are opened at the end of the limiting rotating block 32. The multiple rolling components 331 are all disposed inside the limiting rotating grooves 31. The rolling components 331 are composed of balls 3311 and rolling grooves 3312. The rolling grooves 3312 are opened at the bottom end of the limiting rotating grooves 31. The balls 3311 are disposed inside the rolling grooves 3312. The balls 3311 have a spherical structure. Under the drive of the mixing mechanism 2, the limiting rotating block 32 rotates inside the limiting rotating grooves 31. During this process, the balls 3311 roll inside the rolling grooves 3312 and the inner side of the rolling grooves 332, increasing the smoothness of the limiting rotating block 32 when rotating inside the limiting rotating grooves 31.

[0020] The working principle and usage process of this utility model are as follows: During the operation of the internal mixer, after the material is added from the feeding port, the material is subjected to strong mechanical shearing and kneading through the mixing mechanism 2. At the same time, the mixing mechanism 2 rotates at different speeds, and the material circulates repeatedly in the gap between the surface of the mixing mechanism 2 and the interior of the internal mixer body 1, and is subjected to mechanical stress and thermal oxidation pyrolysis, thereby achieving the required plasticity in a short time. During the rotation of the mixing mechanism 2, the limiting rotating block 32 fixed at the end of the mixing mechanism 2 rotates inside the limiting rotating groove 31, and causes multiple balls 3311 to roll inside the rolling groove 3312 and inside the rolling groove 332, so that there is a certain gap between the mixing mechanism 2 and the inner wall of the internal mixer body 1, which does not affect normal use, thereby increasing the protection of the internal mixer during operation.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
