Description

Technical Field

[0001] The utility model relates to the technical field of rubber internal mixers, in particular to a novel rubber internal mixer. Background Art

[0002] The rubber internal mixer is an important equipment for mixing rubber materials. It is widely used in tire manufacturing, rubber product production and various rubber processing industries. Its main function is to exert a certain shear and compression effect on the rubber material through the relative rotation of the two rollers, so that the rubber material is fully mixed and plasticized under high temperature and high pressure conditions, thereby improving the performance and quality of rubber products. The use of the rubber internal mixer effectively improves the uniformity and processability of rubber materials, and is one of the key equipment in the rubber processing process.

[0003] However, the roller position of the existing rubber mixer is usually fixed and cannot be flexibly adjusted according to the requirements of rubber materials of different materials, resulting in limited mixing effect. It is difficult to achieve the best mixing effect for rubber materials with different hardness or mixing requirements.

[0004] Based on this, those skilled in the art have proposed a novel rubber internal mixer. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a new type of rubber internal mixer.

[0006] The technical solution of the utility model is as follows: a new type of rubber internal mixer, including a casing, two roller bodies are arranged inside the casing, adjustment grooves are opened on both sides of the casing, two sliding blocks are slidably connected inside the adjustment grooves, roller cores at both ends of the roller body are rotatably connected to the corresponding two sliding blocks, two side vertical plates are symmetrically fixedly connected on both sides of the casing, and a driving mechanism and an adjustment mechanism are arranged between the four side vertical plates;

[0007] The driving mechanism includes a connecting rod, which is arranged to have a U-shaped structure and is rotatably connected to the outer side of the corresponding roller body, and two light rods are symmetrically fixedly connected between the two corresponding side vertical plates, and the light rods are slidably connected to the connecting rod, and a spring is sleeved on the outer side of the light rod and located between the corresponding side vertical plate and the connecting rod. One end of the roller body extends to the outer side of the connecting rod and is fixedly connected with a connecting bevel gear, and a driving rod is rotatably connected between the two side vertical plates, and two sliding sleeves are symmetrically slidably connected to the outer side of the driving rod, a key slot is provided on the driving rod, and a flat key used for matching the key slot is provided on the sliding sleeve, and the driving bevel gears are fixedly connected to the sliding sleeve, and the driving bevel gears are meshed with the corresponding connecting bevel gears, and a limiting plate of an L-shaped structure is rotatably connected between the sliding sleeve and the roller core of the corresponding roller body, and a driving motor is fixedly connected to one of the side vertical plates, and the output end of the driving motor is fixedly connected to the driving rod.

[0008] The driving motor drives the driving rod to rotate, and the driving rod drives the sliding sleeve to rotate through the flat key and the keyway, and then drives the driving bevel gear to rotate through the sliding sleeve, and the driving bevel gear meshes with the connecting bevel gear to drive it to rotate, and the rotation of the connecting bevel gear drives the roller body to rotate in the opposite direction, so that the rotation of the two rollers is used to achieve the mixing of the rubber material.

[0009] As a preferred embodiment, the adjustment mechanism includes a base plate, which is fixedly connected between the bottoms of the four side vertical plates, and two mounting plates are symmetrically fixedly connected to the base plate, a bidirectional screw rod is rotatably connected between the mounting plates, the bidirectional screw rod is threadedly connected to two connecting rods, one end of the bidirectional screw rod is fixedly connected to an adjustment disk, two inclined baffles are symmetrically fixedly connected to the interior of the casing, and a discharge baffle is provided on one side of the casing.

[0010] The bidirectional screw is driven to rotate by the adjusting disk. When the bidirectional screw rotates, it can drive the two connecting rods to move, thereby controlling the distance between the two connecting rods, thereby controlling the position of the roller body. Through such a setting, different intensities of mixing can be achieved for rubber materials of different materials.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The bidirectional screw is driven to rotate by the adjusting disk, and the bidirectional screw is threadedly connected to the connecting rod, which can drive the two connecting rods to move, thereby adjusting the distance between the rollers. This design allows the user to accurately adjust the position of the roller according to the requirements of rubber materials of different materials, thereby achieving different strengths of rubber mixing. The driving motor drives the driving rod to rotate, and the driving rod drives the sliding sleeve to rotate through the flat key and the keyway. The sliding sleeve then drives the driving bevel gear to rotate, and the driving bevel gear meshes with the connecting bevel gear, and finally realizes the opposite rotation of the roller. This design ensures that the rollers can rotate synchronously, apply uniform pressure to the rubber material, and ensure the uniformity and efficiency during the mixing process. Through the above settings, the user can easily control the distance between the rollers, thereby flexibly adjusting the pressure applied to the rubber material. This function enables the utility model to adapt to rubber materials of different types and hardness, providing a wider range of applications and higher mixing efficiency.
