Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figures 1 to 6As shown, the embodiment of the utility model proposes a flame retardant masterbatch granulation processing device, including a box body 1, a feed port 2 is installed on the upper end of the box body 1, an extrusion plate 7 is installed on one side of the box body 1, an auxiliary mechanism 4 is installed between the box body 1 and the extrusion plate 7, a plurality of forming holes 8 are penetrated inside the extrusion plate 7, a rotating shaft 5 is installed in the internal movement of the box body 1, a spiral leaf 6 is installed on the outside of the rod body of the rotating shaft 5, and the spiral leaf 6 and the extrusion plate 7 are parallel to each other, the auxiliary mechanism 4 includes an electric push rod 401 and a blade 410, the electric push rod 401 is respectively installed on the upper and lower sides of the box body 1, and a positioning block 403 is respectively installed on the output end of the electric push rod 401, and the positioning block 403 is fitted with the extrusion plate 7, and a groove 406 is provided inside the extrusion plate 7, and a No. 1 connecting pipe 404 is respectively installed inside the positioning block 403, and the No. 1 connecting pipe 404 is connected to the groove 406, and the blade 410 is fitted on the side of the extrusion plate 7 away from the rotating shaft 5, and the blade 410 is connected to the rotating shaft 5.
[0024] like Figures 4 to 6 As shown, in another embodiment of the utility model, the output ends of the electric push rod 401 are respectively fixedly installed with connecting frames 402, and the ends of the connecting frames 402 close to each other are respectively fixedly connected with the positioning blocks 403, and the upper and lower ends of the interior of the groove 406 are respectively fixedly penetrated with the second connecting pipe 405, and the end of the first connecting pipe 404 close to the extrusion plate 7 is clamped and installed in the interior of the second connecting pipe 405, and the positioning block 403 fits with the second connecting pipe 405, and the internal movement of the extrusion plate 7 is penetrated with a transmission rod 409, and the transmission rod 409 is installed. The end of the moving rod 409 close to the spiral blade 6 is snap-connected with the rotating shaft 5, the end of the transmission rod 409 away from the spiral blade 6 is fixedly connected with the blade 410, the end of the transmission rod 409 close to the spiral blade 6 is fixedly installed with a snap-fit block 407, a snap-fit groove 408 is provided on the side of the rotating shaft 5 close to the extrusion plate 7, the snap-fit block 407 is snap-fitted inside the snap-fit groove 408, the snap-fit block 407 and the snap-fit groove 408 are both set to be rectangular, and a motor 3 is installed on the side of the box body 1 away from the extrusion plate 7, and the output end of the motor 3 is connected to the rotating shaft 5.
[0025] The raw material is poured into the box body 1 through the feed port 2, and then the motor 3 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the spiral blade 6 to transport the raw material, and also drives the blade 410 to rotate. Then, after the raw material fits the extrusion plate 7, the raw material is extruded along the forming hole 8. At the same time, the coolant flows into the groove 406 along the No. 1 connecting pipe 404 and the No. 2 connecting pipe 405 located at the upper end. Then, the coolant entering the groove 406 will cool the forming hole 8 and the raw material therein, so that the raw material is initially cooled and solidified while being extruded along the forming hole 8. Finally, after the raw material leaves the inside of the forming hole 8, it is cut into particles by the blade 410.
[0026] When the extrusion plate 7 needs to be installed, the user only needs to snap-fit the extrusion plate 7 to one side of the box body 1, and then the electric push rod 401 will pull the positioning block 403 through the connecting frame 402, so that the positioning block 403 drives the No. 1 connecting pipe 404 to snap into the interior of the No. 2 connecting pipe 405, which can not only realize the preliminary positioning of the extrusion plate 7, but also facilitate the flow of the coolant in the later stage. Then, with the continuous movement of the positioning block 403, after the positioning block 403 and the No. 2 connecting pipe 405 are fitted, the positioning work of the extrusion plate 7 can be realized. The positioning block 403 cooperates with the No. 2 connecting pipe 405 to push the extrusion plate 7, so that it can maintain a stable state and will not fall. Therefore, when the user needs to form raw materials of different diameters in the later stage, he only needs to replace the extrusion plate 7 separately, and the diameter adjustment can be quickly carried out, which is more simple and convenient.
[0027] By injecting the coolant into the groove 406 and letting it flow, the raw material and the coolant can be prevented from coming into contact, and the contamination of the raw material can be minimized. At the same time, the raw material can be cooled and solidified to prevent the raw material from sticking to the blade 410 due to the high temperature when the raw material is extruded and cut by the blade 410. This is simpler and more convenient. The coolant flowing in the groove 406 will eventually be discharged and recycled through the No. 1 connecting pipe 404 and the No. 2 connecting pipe 405 at the lower end, thereby reducing the overall production cost.
[0028] Through the engagement connection between the engagement block 407 and the engagement groove 408 , the rotating shaft 5 can drive the blade 410 to rotate to cut the extruded material into particles, thereby reducing the overall energy consumption.
[0029] The working principle of this flame retardant masterbatch granulation processing device:
[0030] When in use, first the raw material is poured into the interior of the box body 1 through the feed port 2, and then the motor 3 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives the spiral blade 6 to transport the raw material, and also drives the blade 410 to rotate. Then, after the raw material is fitted with the extrusion plate 7, the raw material is extruded along the forming hole 8. At the same time, the coolant flows into the interior of the groove 406 along the No. 1 connecting pipe 404 and the No. 2 connecting pipe 405 located at the upper end. Then, the coolant entering the groove 406 will cool the forming hole 8 and the raw material therein, so that the raw material can be initially cooled and solidified while being extruded along the forming hole 8. Finally, after the raw material leaves the interior of the forming hole 8, it is cut into particles by the blade 410.
[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
