Technical Field

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

[0002] Closed rubber mixer is also called internal mixer, which is mainly used for rubber plasticizing and mixing. Internal mixer is a machine with a pair of rotors with specific shapes rotating relatively, which can plasticize and mix polymer materials intermittently under the closed state of adjustable temperature and pressure. It is mainly composed of internal mixing chamber, rotor, rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base.

[0003] During the use of the rubber internal mixer, a feeding mechanism is required. After searching, the Chinese patent CN219153399U in the prior art discloses a feeding mechanism for a rubber internal mixer, including a base and a driving sleeve, a driving turntable is fixedly installed on the top of the base, and a limit plate is movably installed on the top of the driving turntable. The utility model can directly pour the colloid into the inside of the feeding barrel through the setting of the feeding barrel, and the driving sleeve can be driven by the driving mechanism to adjust the height. Specifically, the threaded rod is driven to rotate by a servo motor, and the threaded sleeve can slide up and down on the surface of the threaded rod. The threaded sleeve can drive the driving sleeve to adjust the height while moving, thereby realizing the height adjustment of the feeding barrel, so as to be suitable for internal mixers of various specifications, and the driving mechanism can be driven to rotate by the driving turntable, which is convenient for driving the feeding barrel to rotate, ensuring the feeding effect, and the practicability is extremely high.

[0004] However, the utility model does not have a corresponding quantitative structure during use, so that when the staff feeds the materials each time, they cannot accurately grasp the feeding amount, which affects the effect of rubber mixing and cannot meet production needs. Therefore, a feeding mechanism of a rubber mixer is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a feeding mechanism for a rubber internal mixer, which has the advantage of quantitative feeding and solves the problem that there is no corresponding quantitative structure, and therefore when the staff feeds each time, they cannot accurately grasp the feeding amount, which affects the effect of rubber mixing and cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism of a rubber internal mixer, comprising a base and a support column fixedly connected to the top of the base, a fixed platform is arranged on one side of the support column, a storage tank extending to the bottom of the fixed platform is arranged on the top of the fixed platform, and a quantitative feeding mechanism is arranged at the bottom of the storage tank;

[0007] The quantitative feeding mechanism includes a fixed frame arranged at the bottom of the storage tank, a connecting pipe is fixedly connected between the fixed frame and the storage tank, an electric push rod is fixedly installed on the inner wall of the fixed frame, a quantitative cylinder is fixedly connected to the output end of the electric push rod, and a sliding baffle is fixedly connected to the top of the quantitative cylinder.

[0008] Furthermore, a through opening connected to the quantitative cylinder is provided inside the sliding baffle, a cover plate is hinged at the bottom of the quantitative cylinder, and the connecting pipe is connected to the quantitative cylinder.

[0009] Furthermore, the front and back sides of the sliding baffle are fixedly connected with positioning blocks extending into the interior of the fixing frame, and the inner wall of the fixing frame is provided with positioning grooves matched with the positioning blocks.

[0010] Furthermore, a support frame is fixedly connected to the interior of the storage tank, a drive motor is fixedly installed on the top of the support frame, a rotating shaft extending to the interior of the storage tank is fixedly connected to the output shaft of the drive motor, and a stirring rod is fixedly installed on the outside of the rotating shaft.

[0011] Furthermore, a servo motor is fixedly connected to the inner bottom wall of the support column, a threaded rod is fixedly connected to the output shaft of the servo motor, and the outer thread of the threaded rod is connected to a lifting cylinder extending to the top of the support column.

[0012] Furthermore, both left and right sides of the lifting cylinder are fixedly connected with limit blocks extending into the interior of the support column, and the inner wall of the support column is provided with limit grooves matched with the limit blocks.

[0013] Furthermore, a connecting plate is fixedly connected between the lifting cylinder and the fixed platform, and a limiting ring for limiting the storage tank is fixedly connected to the outside of the storage tank.

[0014] Compared with the prior art, the utility model provides a feeding mechanism for a rubber internal mixer, which has the following beneficial effects:

[0015] 1. The feeding mechanism of the rubber mixer is provided with a connecting pipe and a metering cylinder, so that the rubber raw material inside the storage tank falls into the metering cylinder by the action of gravity, and then the metering cylinder is driven to move to the right by the electric push rod. When the metering cylinder is completely located on one side of the fixed frame, the rubber raw material inside the metering cylinder pushes the cover plate due to the action of gravity and then falls downward. At this time, the rubber raw material can fall into the rubber mixer, thereby completing the effect of quantitative feeding. At the same time, the amount of each feeding is the capacity of a metering cylinder, and uneven feeding will not be caused.

[0016] 2. The feeding mechanism of the rubber mixer can mix and stir the rubber raw materials in the storage tank by setting a driving motor to drive the rotating shaft and the stirring rod to rotate. There is no need for additional mixing by the staff, which improves the integrity of the device and solves the problem that there is no corresponding quantitative structure. As a result, when the staff feeds each time, they cannot accurately grasp the feeding amount, which affects the effect of rubber mixing and cannot meet production needs.
