Description

Technical Field

[0001] The utility model relates to a pelletizing device, in particular to a modified plastic pelletizing device. Background Art

[0002] Modified plastics refer to plastic products that are processed and modified by filling, blending, reinforcing and other methods on the basis of general plastics and engineering plastics to improve their flame retardancy, strength, impact resistance, toughness and other properties. The modified plastic parts can not only achieve the strength properties of some steel materials, but also have a series of advantages such as light weight, rich colors and easy molding. Therefore, the trend of "replacing steel with plastics" has emerged in many industries, and it is almost impossible to find a material that can replace plastic products on a large scale at this stage.

[0003] In the process of preparing plastics, plastics are often stored and transported in the form of plastic pellets. Plastic manufacturers often use pelletizing devices to pelletize modified plastics. However, when cutting the plastics, a large amount of heat is generated, which may cause the plastic pellets to deform. Most of the existing pelletizing devices do not have a cooling function. Therefore, there is an urgent need for a modified plastic pelletizing device with a cooling function. Utility Model Content

[0004] In order to overcome the disadvantage that most of the prior arts do not have a cooling function, the utility model provides a modified plastic pelletizing device.

[0006] Preferably, the pelletizing mechanism includes an installation frame, a motor, a connecting plate and a cutter. The installation frame is arranged inside the placement frame, and the motor is installed inside the installation frame. The motor output shaft is connected to the connecting plate through a coupling, and the discharge barrel is rotatably connected to the connecting plate. A cutter is arranged on one side of the connecting plate, and the cutter is close to the discharge barrel.

[0007] Preferably, the cooling mechanism comprises a water outlet pipe, a water pump and a water inlet pipe. A water pump is provided on one side of the bottom of the placement frame. The water pump passes through the bottom of the placement frame and is connected to the water outlet pipe. One side of the water pump is connected to the water inlet pipe.

[0008] Preferably, it also includes a fixing frame and a filter screen, the filter screen is installed on the fixing frame, the fixing frame is installed outside the placement frame, and one end of the water inlet pipe is connected to the fixing frame.

[0009] Preferably, an observation window is further included, and the observation window is arranged on the fixing frame.

[0010] Preferably, a plurality of rows of small holes are formed in the discharging barrel.

[0011] Beneficial effects: By providing a water outlet pipe, a water pump and a water inlet pipe, the plastic after pelletizing can be immersed in water for cooling. A filter screen and an installation frame are also provided, which facilitate the recycling of water, achieving the effects of cooling and saving water resources. Description of the Drawings

Detailed Embodiments

[0016] The present utility model will be further described below with reference to the drawings and embodiments.

[0017] Embodiment 1

[0018] A modified plastic pelletizing device, as Figure 1 and Figure 2 shown, includes a base 1, a placing frame 2, a fixing frame 3, a discharging barrel 4, a feeding pipe 401, a pelletizing mechanism and a cooling mechanism. The placing frame 2 is installed on the base 1. The placing frame 2 is cylindrical. The fixing frame 3 is installed on the placing frame 2, and the fixing frame 3 plays a role in fixed installation. The discharging barrel 4 is installed on the fixing frame 3. A large number of small holes are regularly formed on the side surface of the discharging barrel 4. After the plastic raw material in a plasticized and molten state flows into the discharging barrel 4, it will be extruded out through the small holes. The feeding pipe 401 is installed on the discharging barrel 4, and it is convenient to pour the plastic raw material in a plasticized and molten state through the feeding pipe 401. A pelletizing mechanism is arranged in the placing frame 2, and the pelletizing mechanism can pelletize the extruded molten plastic. A cooling mechanism is arranged at the bottom of the placing frame 2, and the cooling mechanism can cool the plastic pellets after pelletizing to prevent the plastic pellets from deforming.

[0019] As Figure 3As shown in the figure, the granulating mechanism includes a mounting frame 5, a motor 6, a connecting plate 7, and a cutting knife 8. Inside the placing frame 2, there is a mounting frame 5 which serves for installation. Inside the mounting frame 5, a motor 6 is installed. The coupling of the output shaft of the motor 6 is connected to a connecting plate 7. The connecting plate 7 is rotatably connected to the material discharging barrel 4. Since the material discharging barrel 4 is fixedly installed on the fixing frame 3, when the connecting plate 7 rotates, it will not drive the material discharging barrel 4 to rotate. On one side of the outermost circle of the connecting plate 7, there is a cutting knife 8 which closely adheres to the lower part of the material discharging barrel 4. When the connecting plate 7 rotates to drive the cutting knife 8 to move along the outer side of the material discharging barrel 4, it can granulate the molten extruded plastic.

[0020] As Figure 2 shown in the figure, the cooling mechanism includes a water outlet pipe 9, a water pump 10, and a water inlet pipe 12. The water outlet pipe 9 is fixedly penetrated through the right side of the bottom of the placing frame 2. The water outlet pipe 9 is installed on the water pump 10. The left side of the water pump 10 is connected to a water inlet pipe 12, and water enters through the water inlet pipe 12.

[0021] When it is necessary to granulate the plastic raw material after plasticizing and melting, pour it into the material discharging barrel 4 from the feed pipe 401. Start the motor 6. The output shaft of the motor 6 drives the connecting plate 7 and the cutting knife 8 thereon to rotate through the coupling to cut the plastic extruded from the material discharging barrel 4. Start the water pump 10. The water pump 10 transports the water entering from the water inlet pipe 12 from the water outlet pipe 9 into the placing frame 2, so that the cut plastic particles are soaked in the water. As the water continuously increases, it drives the plastic particles to float above the placing frame 2 and then fall out.

[0022] Embodiment 2

[0023] Based on Embodiment 1, as Figure 1 shown in the figure, it further includes a fixing frame 11, a filter screen 13, and an observation window 14. The fixing frame 11 is installed with a filter screen 13. The filter screen 13 is circular and the mesh holes of the filter screen 13 are relatively fine, and plastic particles cannot pass through. The fixing frame 11 is installed outside the placing frame 2. The fixing frame 11 can collect the falling plastic particles. The upper left end of the water inlet pipe 12 is communicated with the fixing frame 11, so that the water falling into the fixing frame 11 can enter again from the water inlet pipe 12, achieving the effect of recycling. An observation window 14 is provided on the fixing frame 3, and the observation window 14 is made of a transparent material.

[0024] When the plastic particles float above the placing frame 2, the falling plastic particles fall onto the filter screen 13, and the flowing water passes through the filter screen 13 and flows into the mounting frame 5, and then enters from the water inlet pipe 12 for reuse. Through the observation window 14, the situation of the plastic particles that have completed granulation inside the placing frame 2 can be observed.

[0025] The above-described embodiments merely represent the preferred embodiments of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations, improvements, and substitutions can be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent for the present utility model shall be subject to the appended claims.
