Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pelletizers, in particular to a pelletizer for preparing polystyrene masterbatch for eliminating particle adhesion. Background Technique
[0002] Polystyrene is a polymer synthesized by the free radical addition polymerization reaction of styrene monomers. It is a colorless and transparent thermoplastic. During the preparation of polystyrene masterbatch, a pelletizer is required to cut the formed polystyrene strip.
[0003] During the use of the existing pelletizer, when the polystyrene formed by the extrusion plate is cut by the cutting knife, the granular polystyrene is likely to adhere to the outer side wall of the cutting knife. At the same time, during the process of its cutting and falling, it is likely to adhere to the extrusion plate again, resulting in particle adhesion, affecting the subsequent pelletizing operation, and reducing the practical value of the pelletizer. Content of the Utility Model

At the same time, during the process of its cutting and falling, it is likely to adhere to the extrusion plate again, resulting in particle adhesion, affecting the subsequent pelletizing operation.
[0005] To achieve the above object, the utility model adopts the following technical scheme: A pelletizer for preparing polystyrene masterbatch for eliminating particle adhesion, including a granulator main body, the opening end of the granulator main body is fixedly connected with an extrusion plate, and the top of the granulator main body is fixedly connected with a mounting rod. One end of the mounting rod is fixedly connected with a protective frame. An anti-adhesion mechanism is arranged between the protective frame and the extrusion plate. The anti-adhesion mechanism includes a semi-circular air-blowing plate. The outer side wall of the semi-circular air-blowing plate facing the extrusion plate is equidistantly provided with sub-holes. The inside of each sub-hole is fixedly connected with an inclined air nozzle, and the jet ends of the inclined air nozzles all point to the extrusion plate. One side of the protective frame is fixedly connected with a machine ring frame, and an air compressor is fixedly connected inside the machine ring frame. The air output end of the air compressor is connected to the inside of the semi-circular air-blowing plate through a pipeline.
[0006] By arranging the anti-adhesion mechanism, when the extruded particles are cut by the cutting knife, the air compressor is started. The air compressor introduces compressed gas into the semi-circular air-blowing plate and sprays it to the extrusion plate through each inclined air nozzle, so as to blow the cut particles through the gas, making them quickly separate from the cutting knife, and at the same time accelerating their falling, preventing them from adhering to the outer side wall of the extrusion plate again during the falling process, and further ensuring that the cut polystyrene particles all fall into the cooling pool below, preventing them from adhering to the cutting knife and causing losses.
[0007] In a preferred embodiment, a docking groove is annularly formed at the top of the machine ring frame, and a docking rod is inserted into each docking groove. The tops of the plurality of docking rods are fixedly connected to the same filter cover. The air inlet end of the air compressor is fixedly connected to an air inlet pipe, and the opening end of the air inlet pipe is located inside the filter cover.
[0008] In a preferred embodiment, both ends of the bottom of the semi-circular air blowing plate are fixedly connected with connecting blocks, and a scraping blade is fixedly connected to the side of the connecting block facing the extrusion plate.
[0009] In a preferred embodiment, a mounting block is fixedly connected to the side of the semi-circular air blowing plate near the top end, and the mounting block is fixedly connected to the inner wall of one side of the protective frame.
[0010] In a preferred embodiment, a motor box is fixedly connected to the top of the granulator main body, and a driving motor is fixedly connected to the top inside the motor box of the granulator main body. The output shaft of the driving motor is fixedly connected to a rotating shaft through a coupling, and cutting knives are fixedly connected to the outer side wall of the rotating shaft at equal intervals. The cutting knives are in contact with the outer side wall of the extrusion plate.
[0011] In a preferred embodiment, integration plates are fixedly connected to both sides of the granulator main body where the extrusion plate is located, and vibration transmission plates are fixedly connected to one side of the integration plates at equal intervals. The vibration transmission plates are in contact with the outer side wall of the extrusion plate.
[0012] By providing vibration transmission plates and vibration rods, during the process of cutting the extruded particles, when the vibration rods are in working state, the vibration transmission plates transmit the vibration to the extrusion plate. The extrusion plate in an oscillating state can prevent the cut particles from adhering to the extrusion plate during the falling process, causing loss.
[0013] In a preferred embodiment, two mounting sleeves are fixedly connected to one side of the integration plate, and vibration rods are fixedly connected to the interiors of the two mounting sleeves.
[0014] As can be seen from the above, a pelletizer for preparing polystyrene masterbatch for eliminating particle adhesion provided by the present utility model has the following technical effects: when cutting the extruded particles with a cutting knife, start the air compressor. The air compressor introduces compressed gas into the semi-circular air blowing plate and sprays it towards the extrusion plate through each inclined air nozzle, so as to blow the cut particles through the gas, making them quickly separate from the cutting knife, and at the same time accelerating their falling, avoiding their reattachment to the outer side wall of the extrusion plate during the falling process, and further ensuring that the cut polystyrene particles all fall into the cooling pool below, preventing their adhesion to the cutting knife and causing loss.

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0022] A pelletizer for preparing polystyrene masterbatch to eliminate particle adhesion disclosed by the present utility model is mainly applied to the scenario where in the process of using an existing pelletizer, when the polystyrene formed through the extrusion plate is cut by the cutting knife, the granular polystyrene is likely to adhere to the outer side wall of the cutting knife. At the same time, during the process of its cutting and falling, it is likely to adhere to the extrusion plate again, thus resulting in the situation of particle adhesion and affecting the subsequent pelletizing operation.
[0023] Refer to Figures 1 - 5, A pelletizer for preparing polystyrene masterbatch to eliminate particle adhesion, including a granulator main body 1. One end of the granulator main body 1 is fixedly connected with an extrusion plate 5, and the top of the granulator main body 1 is fixedly connected with a mounting rod 2. One end of the mounting rod 2 is fixedly connected with a protective frame 3. There is an anti-adhesion mechanism 4 between the protective frame 3 and the extrusion plate 5. The anti-adhesion mechanism 4 includes a semi-circular air-blowing plate 401. The outer wall of the semi-circular air-blowing plate 401 facing the extrusion plate 5 is equidistantly provided with sub-holes. Inside each sub-hole, an inclined air nozzle 410 is fixedly connected. The jet ends of the inclined air nozzles 410 all point to the extrusion plate 5. One side of the protective frame 3 is fixedly connected with an annular frame 402, and an air compressor 406 is fixedly connected inside the annular frame 402. The air output end of the air compressor 406 is connected to the inside of the semi-circular air-blowing plate 401 through a pipeline. During the rotation of the cutter 7, it will contact the surface of the scraping blade 403 away from the connecting block 409.
[0024] In a specific application scenario, when the extrusion particles are cut by the cutter 7, the air compressor 406 is started. The air compressor 406 introduces compressed gas into the semi-circular air-blowing plate 401 and sprays it towards the extrusion plate 5 through each inclined air nozzle 410. Thus, the cut particles are blown by the gas, enabling them to quickly separate from the cutter 7 and accelerating their fall, preventing them from adhering to the outer wall of the extrusion plate 5 again during the falling process. Furthermore, it ensures that the cut polystyrene particles all fall into the cooling pool below, preventing them from adhering to the cutter 7 and causing losses.
[0025] It should be noted that during the rotation of the cutter 7, after it cuts the extrusion particles, when the cutter 7 passes by the scraping blade 403, if there are still particles adhering to the cutter 7, the scraping blade 403 will scrape off the adhering particles, further improving the anti-adhesion effect.
[0026] Refer to Figures 1 - 4 , In a preferred embodiment, the top of the annular frame 402 is annularly provided with a docking groove 411, and a docking rod 405 is inserted into each docking groove 411. The tops of the multiple docking rods 405 are fixedly connected with the same filter cover 404. The air intake end of the air compressor 406 is fixedly connected with an intake pipe 407, and the open end of the intake pipe 407 is located inside the filter cover 404. Both ends of the bottom of the semi-circular air-blowing plate 401 are fixedly connected with a connecting block 409, and a scraping blade 403 is fixedly connected to the side of the connecting block 409 facing the extrusion plate 5. One side of the semi-circular air-blowing plate 401 near the top is fixedly connected with a mounting block 408, and the mounting block 408 is fixedly connected to the inner wall of one side of the protective frame 3.
[0027] Refer to Figure 1 、 Figure 2 and Figure 3, in a preferred embodiment, a motor box 8 is fixedly connected to the top of the granulator main body 1, and a driving motor 11 is fixedly connected to the top inside the motor box 8 of the granulator main body 1. The output shaft of the driving motor 11 is fixedly connected to a rotating shaft 6 through a coupling. The outer side wall of the rotating shaft 6 is fixedly connected with cutting knives 7 at equal intervals, and the cutting knives 7 are in contact with the outer side wall of the extrusion plate 5.
[0028] Referring to Figure 1 , Figure 4 and Figure 5 , in a preferred embodiment, integration plates 10 are fixedly connected to both sides of the extrusion plate 5 of the granulator main body 1, and vibration transfer plates 9 are fixedly connected to one side of the integration plates 10 at equal intervals. The vibration transfer plates 9 are in contact with the outer side wall of the extrusion plate 5. Two mounting sleeves 13 are fixedly connected to one side of the integration plate 10, and vibration rods 12 are fixedly connected to the inside of the two mounting sleeves 13.
[0029] Specifically, during the process of cutting the extruded particles, the vibration rods 12 are in a working state. Then, the vibration transfer plates 9 transfer the vibration to the extrusion plate 5. The extrusion plate 5 in an oscillating state can prevent the cut particles from adhering to the extrusion plate 5 during the falling process, causing losses.
[0030] Working principle: When in use, the polystyrene strip is gradually extruded through the extrusion plate 5. During the extrusion process, the driving motor 11 is started. The driving motor 11 drives each cutting knife 7 on the rotating shaft 6 to rotate, thereby cutting the extruded polystyrene strip to form polystyrene particles one by one. During the rotation and cutting process of the cutting knives 7, the air compressor 406 is started. The air compressor 406 introduces compressed gas into the semi-circular air-blowing plate 401 and sprays it towards the extrusion plate 5 through each inclined air nozzle 410, so as to blow the cut particles through the gas, enabling them to be quickly separated from the cutting knives 7 and accelerating their falling speed at the same time, avoiding their adhesion to the cutting knives 7 and the extrusion plate 5. When the cut polystyrene particles fall into the cooling pool below, the granulation operation is completed.
[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution. According to the technical solution of the present invention and its inventive concept, equivalent substitution or change should be covered within the protection scope of the present invention.
