Description

Technical Field

[0001] The utility model relates to the technical field of vacuum kneaders, in particular to a vacuum kneader with good sealing performance. Background Art

[0002] The working principle of the vacuum kneader is that a pair of cooperating and rotating blades (or Z-shaped) produce a strong shearing effect to make semi-dry or rubbery viscous plastics react quickly to obtain uniform mixing and stirring.

[0003] However, in the prior art, during the process of sealing the vacuum kneader, bolts are usually used for sealing, which results in the cover plate and the kneader not being fixed firmly enough, and thus a gap is generated between the cover plate and the kneader, causing air leakage inside the kneader under a vacuum state. To address the above problems, we have introduced a vacuum kneader with good sealing performance. Utility Model Content

[0004] The utility model discloses a vacuum kneader with good sealing performance, which aims to solve the technical problem that in the process of sealing the vacuum kneader, bolts are usually used for sealing, which leads to insufficient fixation between the cover plate and the kneader, and then a gap is generated between the cover plate and the kneader, so that the inside of the kneader will cause air leakage under the vacuum state.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The two gears are connected with each other through the third gear, and the two gears are connected with each other through the third gear, and the two gears are connected with each other through the third gear.

[0007] By setting up, by rotating the third fixed block, the slide rod is driven to rotate on the outside of the rotating rod, and then the slide rod drives the connecting plate to flip the cover plate over the kneader, and the connecting plate slides on the outside of the slide rod, so that the cover plate can cover the kneader in a straight line downward, and when the cover plate moves downward, it can drive the connecting plate to move downward, so that the rotating gear can engage the teeth with the gear, and then the cover plate can be driven to move downward. Compared with traditional bolt fixation, the transmission through the gear can better make the cover plate and the kneader fit more compactly.

[0008] In a preferred embodiment, a sealing groove is provided on the top of the kneader, triangular blocks are fixedly connected to the inside of the sealing groove at equal intervals, a sealing block is fixedly connected to the bottom of the cover plate, triangular grooves are provided on the bottom of the sealing block at equal intervals, and the triangular grooves are used in conjunction with the triangular blocks.

[0009] By setting up, by inserting the sealing block into the interior of the sealing groove, the triangular block is used in conjunction with the triangular groove, thereby increasing the sealing performance between the kneader and the cover plate.

[0010] In a preferred embodiment, a first conical wheel is fixedly connected to the outside of the rotating shaft, a fixed plate is fixedly connected to the outside of the kneading machine and below the first conical wheel, a first servo motor is fixedly connected below the fixed plate, an output shaft of the first servo motor extends to the top of the fixed plate and is fixedly connected to a second conical wheel, and the second conical wheel is meshed and linked with the first conical wheel.

[0011] By setting, the first servo motor drives the second conical wheel to rotate, so that the second conical wheel can drive the first conical wheel to rotate during its rotation, and then the first conical wheel can drive the rotating shaft to rotate, so that the rotating shaft can drive the gear to rotate through the pulley.

[0012] In a preferred embodiment, the interior of the kneader is rotatably connected to a stirring shaft, the exterior of the kneader is fixedly connected to a second servo motor, and the output shaft of the second servo motor is fixedly connected to the stirring shaft.

[0013] By setting, the second servo motor works, thereby driving the stirring shaft to stir the material.

[0014] In a preferred solution, an empty slot is provided on the top of the limiting plate, and a T-block is rotatably connected to the top of the connecting plate, and the T-block is used in conjunction with the empty slot.

[0015] By setting, the T block is passed through the empty slot and then rotated, so that the connecting plate can drive the cover plate to be lifted and fixed upward.

[0016] In a preferred solution, springs are fixedly connected between the limit plate and the connecting plate and on the outside of the slide rod, and the bottom of the kneader is fixedly connected to two bases.

[0017] Through the setting, the elasticity of the spring is used to drive the connecting plate and the cover plate to be pressed downward.

[0018] The vacuum kneader with good sealing performance provided by the utility model has the following advantages:

[0019] First, by rotating the third fixed block, the sliding rod is driven to rotate on the outside of the rotating rod, and then the sliding rod drives the connecting plate to flip the cover plate over the kneader. The connecting plate slides on the outside of the sliding rod, so that the cover plate can cover the kneader in a straight line downward. When the cover plate moves downward, it can drive the connecting plate to move downward, and the rotating gear can mesh with the gear, and then the cover plate can be driven downward. Compared with the traditional bolt fixation, the gear transmission can better make the cover plate and the kneader fit more compactly.

By inserting the sealing block into the sealing groove, the triangular block and the triangular groove are used in conjunction, thereby increasing the sealing between the kneader and the cover plate.
