Description

Technical Field

[0001] The utility model relates to the technical field of HDPE corrugated pipe production, in particular to a raw material mixing device for HDPE corrugated pipe production. Background Art

[0002] HDPE corrugated pipe is a corrugated pipe made of high-density polyethylene (HDPE). It has excellent physical properties and chemical stability and is widely used in drainage, sewage, ventilation, cable protection and other fields. During the entire production process, it is necessary to pay attention to controlling parameters such as temperature and pressure to ensure the stability of the quality of HDPE corrugated pipe. In addition, the waste generated should be recycled or properly disposed of to reduce environmental impact.

[0003] For example, a raw material mixing device for corrugated pipe production disclosed in announcement number CN219076176U includes a stirring box and a premixing mechanism, wherein the premixing mechanism includes a premixing funnel, and a first mounting frame and a second mounting frame are fixedly mounted on the upper surface of the premixing funnel near both sides, and the sides of the first mounting frame and the second mounting frame are provided with sliding grooves, and a first grid is slidably connected in the sliding groove of the first mounting frame, and a second grid is slidably connected in the sliding groove of the second mounting frame. By setting the premixing funnel, stirring motor, rotating shaft, stirring blade, feeding port, first mounting frame, second mounting frame, sliding groove, first grid and second grid, the raw materials can be screened before the raw materials of the corrugated pipe are mixed to avoid the large size difference of the raw materials affecting the later production, and the excessively large ones can be removed to prevent the mixing from jamming and improve the mixing efficiency. However, the device still has certain defects when used;

[0004] When in use, the device only uses a rotating shaft to drive the stirring blade to rotate in the same direction to stir and mix the materials. Since the stirring rod can only rotate in one direction, it is easy to cause uneven mixing. In the process of mixing materials, some materials may not be able to fully contact and mix, resulting in reduced mixing quality and low mixing efficiency.

[0005] Therefore, it is necessary to invent a raw material mixing device for producing HDPE corrugated pipes to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a raw material mixing device for producing HDPE corrugated pipes, so as to solve the problem that the raw material mixing device for producing HDPE corrugated pipes in the technology only rotates with one stirring blade, which may lead to uneven mixing and low efficiency.

[0008] Preferably, the top outer surface of the stirring rod is also provided with a connecting plate, and the outer surface of the connecting plate is provided with a plurality of evenly distributed docking grooves, which can cooperate with the feed port and perform intermittent docking with the feed port to prevent excessive one-time feeding from affecting the mixing effect.

[0009] Preferably, four evenly distributed scrapers are fixedly connected to the bottom of the connecting plate, which can scrape the inner wall of the mixing box to prevent the material from adhering to the inner wall of the mixing box, causing waste or making the mixing box difficult to clean.

[0010] Preferably, a protective cover is provided above the feed port, and sound insulation cotton is provided below the inside of the protective cover to prevent excessive noise during use.

[0011] Preferably, a plurality of heat dissipation holes are provided on the top of the protective cover to dissipate heat and prevent the drive motor from generating excessive heat.

[0012] Preferably, the outer surface of the mixing box is provided with an insulation layer, and a spiral heating wire is provided between the mixing box and the insulation layer. The heating wire and the insulation layer can better control the temperature inside the mixing box during operation, thereby achieving a better mixing effect.

[0013] Preferably, the feed port is made of transparent plastic, which makes it easy to observe whether the feed port is blocked and facilitates timely processing.

[0014] Preferably, the outer surface of the belt in the pulley assembly is coated with an anti-corrosion layer to reduce the wear of the pulley assembly and extend the service life.

Each rotation will drive the transmission gear to rotate half a circle in the forward direction, and drive the incomplete inner gear to rotate one circle through the connecting frame. When the incomplete inner gear rotates one circle, it will drive the transmission gear to rotate half a circle in the reverse direction. The incomplete outer gear and the incomplete inner gear are alternately meshed with the transmission gear to realize continuous forward and reverse rotation of the transmission gear, thereby driving the stirring rod to perform continuous forward and reverse rotation, so as to mix the materials more fully and improve efficiency.

[0017] 2. A connecting plate is provided, and through four evenly distributed docking grooves opened on the surface of the connecting plate, it can intermittently dock with the feed port when it rotates, so as to realize intermittent feeding and prevent excessive one-time feeding and affect the stirring effect.
