Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically to a raw material drying and pelletizing device for preparing matte materials. Background Technology

[0002] In the plastic extrusion production process, plastic raw materials are melted and extruded through an extruder at high temperature. When the plastic melt comes out of the extruder die, it appears as lines. After the molten plastic is cooled in a water tank, it becomes a rigid plastic line. At this time, the plastic has solidified from a molten state to a solid state, but it still has a high temperature of tens of degrees and a lot of water stains on the surface.

[0003] These linear plastic strips enter the pelletizer, which cuts them into pellets tens of millimeters in length. Due to the high extrusion speed, the linear plastic strips have a very short cooling time in the water tank. Most of their high temperature is transferred to the moving blade, stationary blade, rubber roller, and pelletizer itself during the pelletizing process. The higher the temperature, the easier it is for the pelletizer blades to wear. At the same time, the water stains brought from the water tank due to the high extrusion speed will cause water to accumulate inside the pelletizer. In a high temperature and high humidity environment, the pelletizer will rust faster.

[0004] The prior art patent document CN206825545U provides a pelletizer, including a pelletizer body. The pelletizer body is provided with symmetrical partitions at the feed inlet position, and rollers for guiding the material strips into the pelletizer body are provided between the partitions.

[0005] Although the existing technology described above has rollers to facilitate the passage of plastic strips, the problem of high temperature and moisture on the surface of the plastic strips during operation has not been solved. The device cannot effectively cool down and dry the plastic strips during the feeding process, which does not meet people's needs. Therefore, we need a raw material drying and pelletizing device for matte finish preparation. Utility Model Content

[0006] The purpose of this invention is to provide a raw material drying and pelletizing device for preparing matte materials, so as to solve the problem mentioned in the background art that the device cannot effectively cool down and dry the plastic strips during the feeding process.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a raw material drying and pelletizing device for preparing matte material, including a pelletizer body, a fixed outer shell is fixedly connected to the outer wall of the pelletizer body by bolts, and a fan assembly is provided on the top of the fixed outer shell, and a collection assembly is provided on the bottom of the fixed outer shell;

[0008] The fan assembly includes a fan housing, and a cooler is installed on the inner wall of the fan housing.

A spring is fixedly connected to the inner wall of the circular groove, and a round head is fixedly connected to one end of the spring. A ventilation screen is detachably connected to the outer wall of the fixed housing.

[0009] The collection assembly includes a mounting shell, and the inner wall of the mounting shell has a sliding groove. A collection box is slidably connected to the inner wall of the sliding groove, and the inner wall of the collection box has a sealing groove. A sealing ring is provided on the inner wall of the sealing groove, and a transparent plate is fixedly connected to the inner wall of the collection box.

[0010] Preferably, the shape and size of the fan housing match the shape and size of the filter frame, and one end of the filter frame is inserted into the fan housing.

[0011] Preferably, the outer wall shape and size of the filter frame match the inner wall shape and size of the fan housing, and the outer wall of the filter frame fits into the inner wall of the fan housing.

[0012] Preferably, the filter frame forms an elastic structure with a spring and a round head, and one end of the round head extends into the round groove and is connected to the spring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, the raw material drying and pelletizing device for matte finish preparation includes a pelletizer body 1. A fixed outer shell 2 is bolted to the outer wall of the pelletizer body 1. A fan assembly 3 is installed on the top of the fixed outer shell 2, and a collection assembly 4 is installed at the bottom of the fixed outer shell 2. The fan assembly 3 includes a fan housing 301, and a cooler 302 is installed on the inner wall of the fan housing 301. A filter frame 303 is detachably connected to the top of the fan housing 301, and a filter screen 304 is fixedly connected to the inner wall of the filter frame 303. A fixed handle 305 is fixedly connected to the top of the filter frame 303. The inner wall of the filter frame 303 has a circular groove 306, and a spring 307 is fixedly connected to the inner wall of the circular groove 306. One end of the spring 307 is fixedly connected to a round head 308. The outer wall of the fixed housing 2 is detachably connected to a ventilation mesh 309. The collection assembly 4 includes a mounting housing 401, and the inner wall of the mounting housing 401 has a sliding groove 402. The inner wall of the sliding groove 402 is slidably connected to a collection box 403, and the inner wall of the collection box 403 has a sealing groove 404. A sealing ring 405 is provided on the inner wall of the sealing groove 404, and a transparent plate 406 is fixedly connected to the inner wall of the collection box 403.

[0027] Through the above technical solution, the operation of the air cooler 302 generates cold air, which cools the plastic strips before they enter the pelletizer body 1, effectively reducing the temperature of the plastic strips. The filter screen 304 filters the air entering the fan housing 301, preventing dust and other impurities from entering the housing with the outside air. When the filter screen 304 needs to be cleaned, the filter screen frame 303 can be easily removed by pulling up the fixed handle 305. The operation is simple and convenient, facilitating the cleaning and maintenance of the filter screen 304. When the air cooler 302 operates, the cold air blows onto the plastic strips, and the moisture on the plastic strips drips down into the collection box 403 for collection. The transparent plate 406 allows the operator to observe the collection situation in the collection box 403 at any time, and to promptly pull the collection box 403 out of the slide 402 using the handle to treat the collected moisture. The sealing ring 405 ensures the airtightness of the collection box 403, preventing the collected moisture and impurities from flowing out from the gaps. The structure is simple and easy to use.

[0028] Specifically, the shape and size of the fan housing 301 match the shape and size of the filter frame 303, and one end of the filter frame 303 is inserted into the fan housing 301.

[0029] The above technical solution enhances the connection between the fan housing 301 and the filter frame 303, making it easier to remove the filter frame 303 from the fan housing 301. The fan housing 301 is fixed to the top of the fixed housing 2, the mounting housing 401 is fixed to the bottom of the fixed housing 2, the air cooler 302 is powered by an external power supply, the air cooler 302 is controlled by an external controller, and a temperature sensor is installed inside the fixed housing 2.

[0030] Specifically, the outer wall shape and size of the filter frame 303 match the inner wall shape and size of the fan housing 301, and the outer wall of the filter frame 303 fits into the inner wall of the fan housing 301.

[0031] The above technical solution facilitates the insertion of the filter frame 303 into the fan housing 301 for installation, and makes the installation and disassembly of the filter frame 303 convenient. The staff can periodically disassemble the filter frame 303 to clean the filter screen 304.

[0032] Specifically, the filter frame 303 forms an elastic structure with the round head 308 via the spring 307, and one end of the round head 308 extends into the round groove 306 and is connected to the spring 307.

[0033] With the above technical solution, when the filter frame 303 is inserted into the fan housing 301, the round head 308 on the filter frame 303 contacts the inner wall of the fan housing 301. The round head 308 is squeezed and contracted by the inner wall. The contraction and movement of the round head 308 causes the spring 307 to contract. The spring 307 contracts and rebounds. The round head 308 presses against the fan housing 301 through the elastic force of the spring 307, making the filter frame 303 more stable when inserted into the fan housing 301 and less prone to loosening.

[0034] Specifically, there are two ventilation nets 309, and the two ventilation nets 309 are symmetrically arranged with the vertical line of the fixed outer shell 2 as the axis of symmetry.

[0035] With the above technical solution, by setting two ventilation nets 309 and blowing air with a cooler 302, the air can be dispersed from the two ventilation nets 309.

[0036] Specifically, the mounting shell 401 forms a sliding structure with the collection box 403 through the sliding groove 402, and the inner wall of the sliding groove 402 is in contact with the outer wall of the collection box 403.

[0037] The above technical solution enhances the connection between the mounting shell 401, the slide groove 402, and the collection box 403, making it easier for the collection box 403 to slide into the slide groove 402 and facilitating the installation and removal of the collection box 403.

[0038] Specifically, the inner wall shape and size of the sealing groove 404 match the outer wall shape and size of the sealing ring 405, and the inner wall of the sealing groove 404 fits against the outer wall of the sealing ring 405.

[0039] The above technical solution enhances the connection between the sealing groove 404 and the sealing ring 405. By providing the sealing ring 405, moisture is prevented from flowing out from the gap between the collection box 403 and the slide 402.

[0040] During operation, when the plastic strips first enter the pelletizer body 1, the cooler 302 draws in outside air. This outside air is filtered through the filter 304, blocking impurities and dust. The air then enters the fan housing 301 and is cooled by the cooler 302. This cold air blows onto the plastic strips, carrying away heat from their surface and lowering their temperature. The air is then expelled through the ventilation nets 309 on both sides. Simultaneously, it blows away moisture from the surface of the plastic strips. The blown-off moisture drips down into the collection box 403 under gravity and is collected. A sealing ring 405 enhances the seal, preventing moisture from leaking out through gaps. The staff can see the collection situation in the collection box 403 through the transparent plate 406. When a certain amount has been collected, the staff can pull the collection box 403 out of the slide groove 402 of the mounting shell 401 using the handle to clean the collected water and impurities. When cleaning the filter screen 304 regularly, the staff can pull out the filter screen frame 303 using the fixed handle 305 to detach the filter screen frame 303 from the fan shell 301, making it easier for the staff to clean and maintain the filter screen 304. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
