Description

Technical Field

[0001] This utility model relates to the field of plastic granulation production technology, and in particular to a mixing hopper for plastic granulation production. Background Technology

[0002] Currently, in the production process of plastic pellets, the plastic extrusion strips are first extruded from the extruder, then cooled by water in a water tank, and then dried by a plastic extrusion strip dryer. Next, they enter the pelletizer to be cut into plastic pellets. Since the composition of each plastic raw material is not quite the same, the pellets are mixed together. If they are not mixed, the raw materials will be uneven. Therefore, a mixing device is needed to mix the plastic pellets to make them uniform.

[0003] For example, Chinese utility model patent application number 202322214496.X discloses a mixing hopper for plastic granulation production, including a mixing hopper body, telescopic legs, and a conveyor, relating to the field of plastic granulation production technology. This utility model, by installing a conveyor at the bottom discharge port of the mixing hopper body, uses a horizontally arranged screw conveyor to transport the plastic granules within the mixing hopper body, effectively preventing the plastic granules from accumulating at the bottom of the mixing hopper and causing blockage. Furthermore, the discharge speed can be adjusted by controlling the conveyor's rotation speed. Compared with existing technologies, this utility model not only adjusts the discharge speed but also effectively prevents blockage at the discharge port. The telescopic legs not only facilitate the disassembly and installation of the mixing hopper body, improving practicality, but also help adjust the height of the mixing hopper, better meeting usage needs.

[0004] The aforementioned patent requires workers to manually move the plastic granules to the feed hopper and then pour them into the mixing hopper during the plastic granulation and mixing process. However, the feed hopper is located at the top of the mixing hopper, which is inconvenient to move due to its high position. Furthermore, after the filter plate intercepts plastic granules that are significantly larger than normal, workers have to manually clean the intercepted plastic granules to prevent clogging of the feed hopper during the next batch of mixing. This process is time-consuming and labor-intensive and needs improvement. Utility Model Content

A drive wheel 11 is fixedly connected to the output end of the drive motor 10. The drive wheel 11 and the driven wheel 6 are connected by a belt 12.

[0034] The mixing assembly includes a mixing shaft 13 that is rotatably mounted on the top of the mixing hopper body 1. Several mixing blades 14 and mixing blocks 15 are fixedly connected to the outer surface of the mixing shaft 13, and the top end of the mixing shaft 13 is coaxially fixedly connected to the output end of the drive motor 10.

[0035] The filter assembly includes a feeding box 16 fixedly installed on one side of the feeding cylinder 3. A filter screen 17 is fixedly connected between the front and back sides of the inner wall of the feeding box 16. A discharge port 18 is opened on the side of the feeding box 16 away from the feeding cylinder 3. A discharge door 19 is hinged on one side of the feeding box 16 at the position corresponding to the discharge port 18.

[0036] The filter screen 17 is inclined, the bottom of the feeding box 16 is inclined, the bottom of the outer surface of the discharge door 19 is fixedly connected to the handle 20 and the support frame 21, the support frame 21 is movably connected to the inside of the pin 22, and the pin ring 23 is fixedly installed on one side of the feeding box 16 at the position corresponding to the pin 22.

[0037] The side of the filter screen 17 closest to the discharge port 18 is lower, and the side farther from the discharge port 18 is higher. The bottom of the feeding box 16 is lower on the side closest to the feeding port 8, and higher on the side farther from the feeding port 8.

[0041] Working principle: When it is necessary to feed materials into the mixing hopper body 1, the staff first pours the plastic granules into the feeding box 16. At this time, the unqualified (large size) plastic granules are intercepted by the filter screen 17, while the qualified plastic granules will pass through the filter screen 17 and enter the feeding port 8 along the bottom of the feeding box 16, and reach the feeding cylinder 3.

[0042] Next, the drive motor 10 is started. The output shaft of the drive motor 10 rotates, which drives the drive wheel 11 to rotate. Under the transmission action of the belt 12, the driven wheel 6 and the feeding shaft 5 rotate, which pushes the feeding auger 7 to rotate, thereby driving the plastic granules to rise to the discharge port 4. Then the plastic granules fall from the discharge port 4 into the mixing hopper body 1, realizing convenient feeding of plastic granules.

[0043] At the same time, the output end of the drive motor 10 rotates, driving the stirring shaft 13 to rotate synchronously, which in turn drives the stirring blades 14 and the stirring block 15 to rotate, thereby stirring and mixing the plastic particles in the mixing hopper body 1. After the mixing is completed, the solenoid valve on the guide pipe 25 is opened, so that the plastic particles in the mixing hopper body 1 are discharged from the guide pipe 25.

[0044] When it is necessary to clean up the unqualified plastic particles intercepted by the filter screen 17, pull the pin 22 to disengage it from the pin ring 23, release the limiting fixation on the discharge gate 19, and then pull the handle 20 to rotate the discharge gate 19 upward to open the discharge port 18, so that the unqualified plastic particles blocked by the filter screen 17 can be discharged into the collection box 24 through the discharge port 18, thus completing the cleaning of the unqualified plastic particles. The operation is simple and convenient.
