Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire production, and in particular to a feeding device for a mixing mill. Background Technology

[0002] In the production of aircraft tires, the internal mixer is the core equipment in the rubber mixing process. During internal mixing, raw rubber is first added to the mixer, and then various additives such as reinforcing agents, accelerators, and plasticizers are added through a feeding device to mix with the raw rubber, improving the mixing effect. In the prior art, utility model patent application number 202223556752.5 discloses a feeding mechanism for a rubber internal mixer, mainly composed of a base and a feeding cylinder, with a feeding port at the lower end of the feeding cylinder. When feeding material into the internal mixer, the material is added to the feeding cylinder, positioning the cylinder above the mixer's inlet. Then, the feeding port at the lower end of the feeding cylinder is opened, allowing the material to fall into the internal mixer through the cylinder, completing the feeding process. However, this mechanism has the following problems: it only has a feeding function and cannot quantitatively measure the material entering the internal mixer, making it inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a feeding device for internal mixers that can quantitatively measure the amount of additives added, facilitates the monitoring of the weight of the added additives, and is easy to use and highly practical.

The lifting mechanism is mounted on the moving mechanism, the weighing mechanism is mounted on the lifting mechanism, and the feeding mechanism is mounted on the weighing mechanism. The internal mixer is mounted on the base, and a feeding port is provided at the upper end of the internal mixer. When raw rubber is added to the internal mixer, and an additive needs to be added, the additive is placed into the feeding mechanism. Then, the moving mechanism and the lifting mechanism move the indexing plate and the feeding mechanism, moving the feeding mechanism above the feeding port. The indexing plate weighs the feeding mechanism, and then the feeding mechanism adds the additive to the feeding port. The change in weight value on the weighing mechanism is observed until the decrease in weight on the weighing mechanism is the amount of additive to be added. Then, the feeding mechanism is closed to stop feeding. It can quantitatively measure the additive added to the internal mixer, facilitates the monitoring of the added additive weight, is easy to use, and has high practicality.

[0005] Preferably, the moving mechanism includes a linear module and a sliding plate. The linear module is equipped with a sliding plate, and a lifting mechanism is mounted on the sliding plate. The linear module is used to move the sliding plate left and right. When the feeding mechanism is moved left and right, the linear module is opened, and the linear module drives the sliding plate to move in the left and right directions. The sliding plate then drives the lifting mechanism and the feeding mechanism to move in the left and right directions, thus facilitating the movement of the feeding mechanism.

[0006] Preferably, the lifting mechanism includes a hydraulic cylinder, a push rod, a fixed column, a sliding column, and a lifting plate. The hydraulic cylinder is fixedly installed on the upper end of the sliding plate, and a push rod is provided at the output end of the hydraulic cylinder.

The lifting plate is fixedly installed on the upper end of the sliding column and the push rod, and the weighing mechanism is installed on the upper end of the lifting plate. When the height of the feeding mechanism is adjusted, the hydraulic cylinder is opened. The hydraulic cylinder, through the push rod, causes the fixed column to drive the sliding column and the lifting plate to adjust the height, thereby adjusting the height of the weighing mechanism and the feeding mechanism, which facilitates the adjustment of the feeding height.

[0007] Preferably, the weighing mechanism includes a weighing scale, which is fixedly installed on the upper end of the lifting plate.

[0008] Preferably, the feeding mechanism includes an indexing plate, a three-jaw chuck, a support shaft, multiple connecting plates, and multiple cylinders.

Each of the multiple cylinders is provided with a feeding funnel at its lower part, and each of the multiple feeding funnels is provided with a discharge pipe, and each of the multiple discharge pipes is provided with a solenoid valve. The indexing plate and the multiple solenoid valves are all connected to an external controller. Multiple additives are placed in the multiple cylinders. When feeding into the internal mixer, the three-jaw chuck is opened, and the three-jaw chuck rotates the multiple cylinders through the support shaft, causing the cylinder containing the specified additives to rotate above the feeding port. Then, the solenoid valve below it is opened, allowing the additives in the cylinder to fall into the feeding port. The weight of the additives fed into the internal mixer can be estimated based on the difference in the value displayed on the indexing plate before and after feeding the additives into the feeding port.

[0009] Preferably, it also includes a support column, a fixing plate, and a crushing mechanism. The fixing plate is mounted on the base via the support column, and the crushing mechanism is mounted on the fixing plate. When the additive in the cylinder clumps together and needs to be crushed, the cylinder containing the clumped additive is moved to the crushing mechanism, and then the clumped additive is crushed by the crushing mechanism.

The motor is fixedly mounted on the upper end of a fixed plate, and the rotating shaft is rotatably mounted on the fixed plate. The upper end of the rotating shaft is connected to the power output end of the motor, and the multiple pulverizing blades are all fixedly mounted on the rotating shaft. When pulverizing the additives in the cylinder, the cylinder is moved so that the multiple pulverizing blades are located in the cylinder. Then, the motor is turned on to rotate the rotating shaft and the multiple pulverizing blades to pulverize the additives in the cylinder.
