Description

Technical Field

[0001] The utility model relates to the technical field of polymer material processing, in particular to a polymer material raw material mixing device with a raw material screening structure. Background Art

[0002] During the manufacturing process of polymer materials, various raw materials need to be mixed first, but the existing polymer material raw material mixing devices have certain disadvantages when used. First, when mixing and stirring the polymer material raw materials, it is inconvenient to disassemble the stirring tank, which is not conducive to the maintenance of the stirring tank or the replacement of damaged parts. In addition, the polymer material raw materials often contain large particles, which reduces the mixing and stirring rate and makes the polymer material raw materials mixed unevenly.

[0003] For example, Chinese patent publication No. CN213408524U discloses a polymer raw material mixing and stirring device. When the parts in the stirring tank need to be repaired or replaced, the bolts are first separated from the small holes, and then the stirring tank body is pulled upward by the handle until the stirring tank body and the lower tank body are completely separated and the interior is completely exposed. Then, repair or replacement of damaged parts can be carried out, which is more convenient. The disassembly process between the lower tank body and the stirring tank body is more convenient, which is conducive to separate maintenance of the stirring tank. By providing a rotating rod, a support plate and a second motor, when the polymer raw material enters the stirring tank through the feed port, the rotating rod is acted on by the second motor, so that the second motor drives the rotating rod to rotate together, which has a good crushing effect on large solid particles in the polymer raw material, and is conducive to accelerating the mixing and stirring rate of the polymer raw material.

[0004] However, the polymer material raw material mixing and stirring device in the above application requires that the particle sizes of the raw materials be roughly consistent when mixing the raw materials. Therefore, the raw materials need to be screened before mixing and stirring.

[0005] For this reason, we urgently need to provide a polymer material raw material mixing device with a raw material screening structure. Utility Model Content

[0006] The purpose of the utility model is to provide a polymer material raw material mixing device with a raw material screening structure to solve the problem that the polymer material raw material mixing and stirring device proposed in the above background technology requires that the particle sizes of the raw materials be roughly consistent when mixing the raw materials, but the device is not provided with a corresponding mechanism.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a polymer material raw material mixing device with a raw material screening structure, comprising a mixing tank and a screening box, the screening box is installed on the top of the mixing tank, a screening device is arranged inside the screening box, and a mixing device is arranged inside the mixing tank.

[0008] The screening device comprises a screening unit and a feeding unit.

[0009] The screening unit includes a mounting block, a vibration spring, a screening plate, and a vibration assembly. The four mounting blocks are respectively installed on the left and right ends of the front and rear sides of the interior of the screening box. The four vibration springs are respectively fixedly connected to the top of the mounting blocks. The screening plate is fixedly connected to the top of the vibration spring, and screening holes are evenly opened on its upper surface. The vibration assembly is installed on the right outer surface of the screening box.

[0010] A further improvement is that the vibration assembly includes a drive motor, a fixed bearing, a rotating shaft, and an arc-shaped impact plate. The drive motor is installed on the right outer surface of the screening box, the fixed bearing is installed inside the right outer surface of the screening box, the rotating shaft is connected to the output end of the drive motor and is rotatably connected to the inside of the fixed bearing, and the arc-shaped impact plate is fixedly connected to the left end of the rotating shaft. When the raw material falls on the screening plate, the drive motor is started to drive the rotating shaft to rotate inside the fixed bearing, thereby driving the arc-shaped impact plate to rotate and impact the screening plate, thereby driving the screening plate to vibrate up and down on the vibration spring, thereby screening the raw material on the screening plate.

[0011] A further improvement is that the feeding unit includes a feeding pipe, a feeding hopper, a feeding assembly, and a delivery pipe. The feeding pipe is installed on the right side of the mixing tank, the feeding hopper is fixedly connected to the bottom right side of the feeding pipe, the feeding assembly is installed inside the feeding pipe, and the delivery pipe is fixedly connected to the left top of the feeding pipe, and its left end extends into the interior of the screening box.

[0012] A further improvement is that the feeding assembly includes a lifting motor, a rotating shaft, and a lifting auger. The lifting motor is installed at the top center of the feeding pipe, the rotating shaft is connected to the output end of the lifting motor, and its bottom extends into the inner bottom of the feeding pipe.

No manual loading is required, which is more convenient and quick.

[0013] A further improvement is that the bottom of the screening box is an oblique cone structure, the left outer surface of the screening box is fixedly connected to the slag discharge pipe, the feed pipe is fixedly connected to the bottom of the screening box, and its bottom extends into the interior of the mixing tank. The screening box with an oblique cone structure is more convenient for discharging, and the screened raw materials are fed into the interior of the mixing tank through the feed pipe, while raw materials with larger particles are discharged through the slag discharge pipe during the vibration screening process.
