Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a high-speed mixer for producing flame-retardant plastics. Background Art

[0002] High-speed mixer is one of the commonly used equipment in the production of flame-retardant plastics. It is mainly used to mix plastic particles of different types and sizes together, and can also add some additives and flame retardants.

[0003] The Chinese patent "A high-speed mixer for the production of engineering plastic particles" authorization announcement number "CN 217514297U" can evenly mix the crushed materials through the interaction between the motor, the crushing push rod and the stirring blades, preventing uneven mixing and poor mixing effect due to material agglomeration.

[0004] Because the stirring blades can usually only stir the materials in one direction, the stirring force is relatively weak, making it difficult to fully mix the plastic particles, which in turn affects the efficiency of plastic production.

[0005] Therefore, a high-speed mixer for producing flame-retardant plastics is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a high-speed mixer for the production of flame-retardant plastics in order to solve the above problems, thereby improving the problem that the stirring blades are difficult to fully mix the plastic particles.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. A high-speed mixer for flame-retardant plastic production comprises: a workbench, a mixing barrel is fixedly connected to the top of the workbench, first pulleys are arranged on both sides of the inner wall of the workbench, the surfaces of the two first pulleys are transmission-connected with first belts, and a stirring mechanism is arranged on the inner wall of the mixing barrel; wherein the stirring mechanism comprises a rotating rod fixedly connected to the top of one of the first pulleys, the surface of the rotating rod is rotationally connected to the inner wall of the mixing barrel, two fixed blocks are fixedly connected to the surface of the rotating rod, both sides of the inner wall of the fixed block are rotationally connected with breaking shafts, the inner wall of the rotating rod is rotationally connected with two toggle shafts, the surface of the rotating rod is fixedly connected to a driven frame, the surface of the driven frame contacts the inner wall of the mixing barrel, and a driving component is arranged on the inner wall of the mixing barrel.

[0008] Preferably, the driving assembly includes an active rod rotatably connected to the inner wall of the rotating rod, the surface of the active rod is fixedly connected with three first bevel gears, the bottom end of the first bevel gear is meshed with a second bevel gear, one end of one of the second bevel gears is fixedly connected to a driven rod, one end of the other two second bevel gears is fixedly connected to one end of the toggle shaft, the surface of the driven rod is fixedly connected with a third bevel gear, one end of the third bevel gear is meshed with a fourth bevel gear, the top of the fourth bevel gear is fixedly connected to the bottom end of the breaking up shaft, the active rod and the bottom ends of the first pulley are both fixedly connected to the second pulley, the surfaces of the two second pulleys are transmission-connected with a second belt, the first pulley rotates to drive the rotating rod to rotate and drive the breaking up shaft and the toggle shaft to rotate, the rotating rod rotates to drive the breaking up shaft, the driven frame and the toggle shaft to move in a circular shape in the mixing barrel, the breaking up shaft rotates to break up the agglomerated materials in the mixing barrel, and the toggle shaft rotates to stir and mix the materials in the mixing barrel, thereby improving the full mixing of the materials and ensuring the production efficiency of flame retardant plastics.

[0009] Preferably, the inner wall of the driven frame is fixedly connected with push plates distributed in equal rows, and the push plates are used to push the materials in the mixing barrel to ensure that the materials can be fully mixed.

[0010] Preferably, a protective frame is fixedly connected to the bottom of one of the fixed blocks, and the surface of the driven rod is rotatably connected to the inner wall of the protective frame. The protective frame is used to prevent the material in the mixing barrel from adhering to the third bevel gear and the fourth bevel gear, thereby reducing the wear rate of the third bevel gear and the fourth bevel gear and ensuring the service life of the third bevel gear and the fourth bevel gear.

[0011] Preferably, an anti-sticking block is fixedly connected to the top of one of the fixed blocks, and the anti-sticking block is used to prevent materials from adhering to the top of one of the fixed blocks.

[0012] Preferably, a support block is fixedly connected to the inner wall of the workbench, and the bottom end of the second pulley is rotatably connected to the inner wall of the support block. The support block is used to support and limit the second pulley to ensure the normal operation of the second pulley.

[0013] The beneficial effects of the utility model are:

[0014] 1. The rotation of the first pulley drives the rotating rod and the driving breaking shaft and the toggle shaft to rotate. The rotation of the rotating rod drives the breaking shaft, the driven frame and the toggle shaft to move in a circular shape in the mixing barrel, thereby increasing the fluidity of the material in the mixing barrel. Because the breaking blocks on the two breaking shafts are staggered, the breaking shaft rotates to fully break up the agglomerated materials in the mixing barrel.

[0015] 2. The protective frame is used to prevent the material in the mixing barrel from adhering to the third bevel gear and the fourth bevel gear, thereby reducing the wear rate of the third bevel gear and the fourth bevel gear and ensuring the service life of the third bevel gear and the fourth bevel gear.

[0023] like Figure 2-4 As shown, the driving assembly 506 includes an active rod 5061 rotatably connected to the inner wall of the rotating rod 501, and the surface of the active rod 5061 is fixedly connected with three first bevel gears 5062, and the bottom ends of the first bevel gears 5062 are meshedly connected with second bevel gears 5063, one end of one of the second bevel gears 5063 is fixedly connected to a driven rod 5064, and one end of the other two second bevel gears 5063 is fixedly connected to one end of the shifting shaft 504, and the surface of the driven rod 5064 is fixedly connected to a third bevel gear 5065, and one end of the third bevel gear 5065 is meshedly connected with a fourth bevel gear 5066, and the top end of the fourth bevel gear 5066 is fixedly connected to the At the bottom end, the active rod 5061 and the bottom end of the first pulley 3 are fixedly connected with a second pulley 5067, the surfaces of the two second pulleys 5067 are transmission-connected with a second belt 5068, the inner wall of the driven frame 505 is fixedly connected with push plates 5069 distributed in equal rows, the bottom of one of the fixed blocks 502 is fixedly connected with a protective frame 50610, the surface of the driven rod 5064 is rotationally connected to the inner wall of the protective frame 50610, the top of one of the fixed blocks 502 is fixedly connected with an anti-sticking block 50611, the top of the workbench 1 is fixedly connected with a servo motor, the output shaft of the servo motor is rotationally connected to the inner wall of the workbench 1, and the output shaft of the servo motor is fixedly connected to the top of one of the first pulleys 3;

[0024] When it is necessary to produce flame-retardant plastic, the material is poured into the mixing barrel 2 and the first pulley 3 is driven to rotate. The rotation of the first pulley 3 drives the rotating rod 501 and the corresponding second pulley 5067 to rotate. The corresponding second pulley 5067 rotates through the second belt 5068 and another second pulley 5067 to drive the active rod 5061 to rotate. The rotation of the rotating rod 501 drives the breaking shaft 503, the driven frame 505 and the toggle shaft 504 to move in a circular shape in the mixing barrel 2, thereby increasing the fluidity of the material in the mixing barrel 2. The rotation of the active rod 5061 drives the three first bevel gears 5062 to rotate at the same time. The rotation of the first bevel gear 5062 drives the second bevel gear 5063 to rotate. The three second bevel gears 5063 are driven to rotate. The rotation of the bevel gear 5063 drives the driven rod 5064 and the toggle shaft 504 to rotate respectively.

[0026] When the utility model is in use, when it is necessary to produce flame-retardant plastics, the material is poured into the mixing barrel 2 and the first pulley 3 is driven to rotate. The first pulley 3 rotates to drive the rotating rod 501 and the corresponding second pulley 5067 to rotate. The corresponding second pulley 5067 rotates through the second belt 5068 and another second pulley 5067 to drive the active rod 5061 to rotate. The rotating rod 501 rotates to drive the breaking shaft 503, the driven frame 505 and the toggle shaft 504 to move in a circular shape in the mixing barrel 2, thereby increasing the fluidity of the material in the mixing barrel 2. The active rod 5061 rotates through the first bevel gear 5062 and the second bevel gear 5063 drives the driven rod 5064 and the toggle shaft 504 to rotate respectively. The driven rod 5064 rotates through the third bevel gear 5065 and the fourth bevel gear 5066 to drive the breaking shaft 503 to rotate. Because the breaking blocks on the two breaking shafts 503 are staggered, the breaking shaft 503 rotates to fully break up the agglomerated materials in the mixing barrel 2. Because the toggle blocks on the toggle shaft 504 are staggered, the toggle shaft 504 rotates and moves to fully stir and mix the materials in the mixing barrel 2. The movement of the driven frame 505 and the push plate 5069 improves the fluidity of the materials in the mixing barrel 2, improves the full mixing of the materials, and ensures the production efficiency of flame-retardant plastics.
