Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a water-cooled granulating device for a granulator. Background Art

[0002] At present, the granulator is a molding machine that can make materials into specific shapes. Plastic granulation is a process of plastic mechanical processing. The plastic granulator equipment mainly includes a preheating device, a cooling device and an extruder. The auxiliary equipment selected for the extruder unit is different for different purposes, such as a pelletizing device, a blow dryer, etc. Since the granulator is often used in some production, it is necessary to optimize the structure of the granulator.

[0003] For example, a Chinese utility model patent with the announcement number CN214163631 U discloses a pelletizing mechanism of a pelletizer. In the above prior art, although the pelletizer knife can reciprocate up and down through the special design of the push rod groove and the push rod, and utilizes the reset effect of the spring to perform pelletizing, the pelletizer will make the discharged material have a very high temperature during operation. Usually, the pelletizing process can only be carried out after the material is cooled to a certain degree. Such waiting will waste a lot of time and affect production efficiency. When the material is pelletized, if the material is not cooled enough, it will cause the shape to be unstable, deformed or broken during the pelletizing process. Moreover, due to the high temperature of the pellets, the cutter of the pelletizer may be thermally damaged, reducing its service life. Therefore, it is necessary to design a water-cooled pelletizing device for the pelletizer that can quickly cool and pelletize the material produced by the pelletizer. Utility Model Content

[0014] Through the above technical solution, the servo motor is started and cooperated with the two driving gears to make the two rotating rods drive the conveying rollers to rotate.

[0015] As a further improvement of the above solution, a collecting box is provided on one side of the pelletizing plate.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A water-cooled pelletizing device for a granulator in this embodiment comprises a granulator body 1 and a water-cooling box 2 arranged on one side of the granulator body 1, a conveying component for conveying and pulling materials is arranged inside the water-cooling box 2, a pelletizing component for pelletizing the conveyed materials is arranged on one side of the conveying component, a first driving component for driving the pelletizing component to perform pelletizing when the conveying component is in operation is arranged on both sides of the pelletizing component, and a second driving component for driving the conveying component to operate is arranged on one side of the water-cooling box 2.

[0026] Combination Figure 2The conveying assembly includes two rotating rods 301 rotatably arranged inside the water-cooling box 2 and conveying rollers 302 fixedly mounted on each rotating rod 301. The circumferential surfaces of the two conveying rollers 302 are provided with a plurality of conveying grooves adapted to the conveyed materials. The same ends of the two rotating rods 301 penetrate the water-cooling box 2. The two conveying rollers 302 can clamp and convey the materials by rotating.

[0027] Combination Figure 3 The pelletizing assembly includes a pelletizing plate 401 fixedly installed inside the water cooling box 2 and a cutting knife 402 arranged on one side of the pelletizing plate 401. One side of the pelletizing plate 401 is provided with a plurality of feeding holes penetrating the pelletizing plate 401. A cutting groove matched with the cutting knife 402 is opened on the top of the pelletizing plate 401. A pushing plate 7 is fixedly installed on one side of the cutting knife 402. A limiting plate 8 fixedly installed on one side of the pushing plate 7 is provided with a plurality of limiting columns 9 with one end penetrating the limiting plate 8. A plurality of limiting columns 9 are each provided with a pushing spring 10 with one end fixedly installed with the limiting plate 8 and the other end fixedly installed with the pushing plate 7. When the material passes through the feeding hole of the pelletizing plate 401, the cutting knife 402 falls into the cutting groove to pelletize the material.

[0028] Combination Figure 1 and Figure 3 Sliding grooves are provided on both sides of the inner wall of the water cooling box 2. The first driving component includes a pushing column 501 fixedly installed on both sides of the pushing plate 7 and a pushing block 502 fixedly mounted at both ends of one of the rotating rods 301. One end of the two pushing columns 501 extends to the inside of the adjacent sliding groove. When the rotating rod 301 rotates, the pushing block 502 will push the pushing column 501, so that the cutting knife 402 moves up and down to complete the pelletizing.

[0029] Combination Figure 2 and Figure 3 The second driving assembly includes a servo motor 601 arranged on one side of the water cooling box 2 and a driving gear 602 fixedly mounted on two rotating rods 301. The two driving gears 602 are meshed with each other. One end of one rotating rod 301 is fixedly installed on the output end of the servo motor 601. When the servo motor 601 is started and cooperates with the two driving gears 602, the two rotating rods 301 will drive the conveying rollers 302 to rotate.

[0030] Combination Figure 1 A collecting box 11 is provided on one side of the pelletizing plate 401. After the cutting knife 402 completes pelletizing, the pellets will fall into the collecting box 11 and be collected.

[0031] The implementation principle of a water-cooled pelletizing device for a pelletizer in the embodiment of the present application is as follows: when the pelletizer body 1 is in production, the produced material will enter the water cooling box 2 and be cooled by water at an accelerated rate, and the servo motor 601 will be started. Under the cooperation of the two meshing driving gears 602, the two rotating rods 301 will drive the conveying rollers 302 to rotate, and the material will be inserted into the conveying grooves of the two conveying rollers 302, so that the material will be automatically pulled and conveyed through the material passing hole of the pelletizing plate 401. When the rotating rod 301 rotates, the pushing block 502 will also rotate, and the hexagonal pushing block 502 will have a part of its position in contact with the pushing column 501 and push the pushing column 501. Since the pushing column 501 is The sliding groove is limited so that it can only drive the push plate 7 to move upward, thereby driving the cutting knife 402 to move upward together. The continuous rotation of the push block 502 will separate the sharp corner from the push column 501, so that under the push of the push spring 10, the push plate 7 will drive the cutting knife 402 to move downward to pelletize the material. The pelletizing length can be controlled by adjusting the push block 502. Although the device cuts the material in the water, the water resistance is not enough to prevent the device from operating. When the water temperature inside the water cooling box 2 rises, the water can be replaced. This arrangement can not only accelerate the cooling of the material produced by the granulator body 1, but also automatically complete the pelletizing process of the material in the water, which can greatly improve the production efficiency.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
