Description

Technical Field

[0001] This utility model relates to the technical field of feeding internal mixers, and in particular to a rubber-grabbing device for internal mixers. Background Technology

[0002] A closed-type rubber mixing mill, also known as an internal mixer or kneader, is mainly used for the plasticizing and mixing of rubber. During processing, multiple ingredients need to be added to the internal mixer in batches. Existing technology publication number CN211842691U discloses a rubber gripper for an internal mixer, positioned above the conveyor belt. The gripper includes a cylinder and gripping claws. One end of the cylinder is connected to a track, and the other end is connected to the gripping claws. The gripper moves in the X-axis on the track and in the Y-axis on a gantry. A control device is connected to the side of the track and is connected to the gripper via a circuit. Under the control of the control device, the gripper raises and lowers the gripping claws via the cylinder. However, this design is inconvenient for gripping rubber granules and for controlling the amount of material added, resulting in poor practicality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rubber gripping device for a mixer that increases the working range, can grip rubber particles, facilitates control of the feeding quantity, and improves practicality.

[0004] This utility model discloses a rubber-gripping device for an internal mixer, comprising multiple upright legs, multiple base plates, two fixed beams, a movable beam, a moving component, a position adjustment component, a lifting component, and a gripping component. The base plates are installed at the bottom of the upright legs, and the fixed beams are installed at the top of the left and right upright legs. The left and right ends of the movable beam are mounted on the bottom of the fixed beams via the moving component. The lifting component is mounted on the movable beam via the position adjustment component, and the gripping component is mounted on the lifting component. In use, the upright legs are installed around the internal mixer, the base plates increase the ground support area, the moving component can drive the movable beam to move back and forth, and the position adjustment component can move the lifting component left and right. The lifting component drives the gripping component to move downwards, enabling the gripping of rubber granules and facilitating control of the feeding quantity.

[0005] Preferably, the moving component includes two linear motors, two moving blocks, and two sets of limiting sliders. A moving groove is provided at the bottom of the fixed beam, and the linear motors are installed within the moving grooves. Moving blocks are installed at the output ends of the linear motors and slidably mounted within the moving grooves. The top of the moving beam is connected to the bottom of the moving blocks. Limiting grooves are provided at both ends of the fixed beam, and limiting sliders are slidably mounted within these grooves. The bottom of the limiting sliders is connected to the top of the moving beam. Starting the linear motors drives the moving blocks to move within the moving grooves, adjusting the front-to-back position of the moving beam. When the moving beam moves, it drives the limiting sliders to move within the limiting grooves, providing limiting guidance and increasing the connection strength between the moving beam and the fixed beam, ensuring stability.

[0006] Preferably, the position adjustment component includes a moving frame, two guide sliders, a drive box, a servo motor, and a drive gear. The moving frame is slidably mounted on the outer wall of the moving beam. Guide grooves are provided at both ends of the moving beam.

The output end of the servo motor is connected to the input end of the drive gear. A drive port is provided at the top of the moving frame, and a straight tooth groove is provided at the top of the moving beam. The drive gear meshes with the straight tooth groove. When the servo motor is started, it drives the drive gear to rotate and, through its engagement with the straight tooth groove, causes the moving frame to slide on the moving beam, adjusting the left and right positions and increasing the working range. When the moving frame moves, it causes the guide sliders to slide in the guide grooves, enhancing structural strength and ensuring stability.

[0007] Preferably, the lifting component includes a fixed plate, two telescopic cylinders, and a cross-shaped fixing frame. The fixed plate is installed at the bottom of the moving frame, and a reinforcing rib is provided between the top of the fixed plate and the outer walls of the front and rear sides of the moving frame. Telescopic cylinders are installed on the front and rear sides of the fixed plate, and a cross-shaped fixing frame is installed between the two telescopic cylinders. Activating the telescopic cylinders can adjust the gripping height. The reinforcing ribs and the cross-shaped fixing frame increase the structural strength and ensure the stability during gripping and lifting.

[0008] Preferably, the gripping component includes a mounting plate, a rotating rod, a gripping motor, two gripping sliders, and two gripping arc plates. The top of the mounting plate is connected to the bottom telescopic end of the telescopic cylinder. A gripping groove is provided at the bottom of the mounting plate. The rotating rod is rotatably mounted in the gripping groove. Threaded grooves are symmetrically provided at both ends of the rotating rod. The input end of the rotating rod passes through the gripping groove and connects to the output end of the gripping motor. The two gripping sliders are symmetrically slidably mounted in the gripping groove. A gripping arc plate is installed at the bottom of the gripping slider. After moving to the material picking position, the gripping motor is started to drive the rotating rod to rotate. The rotating rod pushes the gripping sliders to move within the gripping groove, allowing the two gripping arc plates to grip the rubber particles, making it convenient to use.

[0009] Preferably, the assembly also includes an intermediate arc plate, an electric telescopic rod, a stopper block, and a controller. The intermediate arc plate is installed at the bottom center of the mounting plate, and a discharge hole is provided at the bottom of the intermediate arc plate. The electric telescopic rod is installed at the top center of the intermediate arc plate, and a stopper block is installed at the bottom telescopic end of the electric telescopic rod. The stopper block cooperates with the discharge hole. The controller is installed on the outer wall of the vertical leg. After the two gripping arc plates grip the rubber granules, the rubber granules are located between the two gripping arc plates and the intermediate arc plate. Activating the electric telescopic rod drives the stopper block to move upward and open the discharge hole, allowing the rubber granules to enter the internal mixer through the discharge hole. This facilitates control of the discharge quantity, and the controller facilitates equipment control.
