Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0035] like Figures 1 to 5 As shown, the utility model provides a polymerization device for producing polyphosphate, including a mixing barrel 1 placed on the ground for mixing and a barrel cover 2 plugged into the upper part of the mixing barrel 1 for sealing, and a pressing mechanism 6 is arranged on the upper part of the mixing barrel 1.

[0036] The pressing mechanism 6 includes a longitudinal rotating rod 66 that movably passes through the middle of the truss 11, and the longitudinal rotating rod 66 is welded and fixed to the lower surface of the middle part of the turntable 33, and the side surface of the longitudinal rotating rod 66 away from the truss 11 is welded and fixed to the side surface of the first bevel gear 61, and the side surface of the first bevel gear 61 is meshed with the side surface of the second bevel gear 65, and the side surface of the second bevel gear 65 away from the first bevel gear 61 is welded and fixed to one end surface of the transverse rotating rod 64, and the side surface of the transverse rotating rod 64 away from the second bevel gear 65 is welded and fixed to one side surface of the cam 62. The rotation of the first bevel gear 61 drives the rotation of the second bevel gear 65 to make the cam 62 perform longitudinal rotation movement (such as Figure 4 As shown), one side of the fixing rod 63 is welded and fixed to the lower surface of one side of the truss 11, and the internal rotation axis of the fixing rod 63 at one end away from the truss 11 is movably interlaced with the middle surface of the transverse rotation rod 64.

[0037] The material changing mechanism 3 includes a servo motor 35 that passes through the upper surface of one side of the truss 11, and the fixed end of the servo motor 35 is fixedly connected to the truss 11 by bolts, and a gear is fixedly arranged at the output end of the servo motor 35, and the gear and the outer surface of the gear ring 36 are engaged with each other, and the inner surface of the gear ring 36 is welded and fixed to the outer surface of the turntable 33, and the rotation of the gear at the output end of the servo motor 35 drives the gear ring 36 to rotate, thereby driving the turntable 33 to rotate, and a plurality of through holes are provided on the upper surface of the turntable 33 for plugging in a plurality of material receiving barrels 12, and the material receiving barrels 12 are arranged in a shape with a large upper opening and a small lower opening, and The diameter of the through hole is larger than the diameter of the lower opening of the material receiving barrel 12, and smaller than the diameter of the middle opening of the material receiving barrel 12. Several material receiving barrels 12 are grouped according to the type of mixing materials, and the lower openings of the inner cavities of several material receiving barrels 12 are all clamped with round plastic plugs 5, and the upper semicircular diameter of the round plastic plugs 5 is larger than the lower opening diameter of the material receiving barrel 12, and the lower semicircular diameter is smaller than the lower opening diameter of the material receiving barrel 12, and the round plastic plugs 5 can be lifted up and play a role in blocking the lower opening of the material receiving barrel 12, and the outer circle of the lower surface of the turntable 33 is provided with a ring groove 31 for the ring rod 32 to be inserted and rotated. The size of each receiving pipe 7 needs to be set according to actual needs, such as 50ml, 100ml, etc. The volume is quantified in advance, and then the material can be discharged by moving the round plastic plug 5 upward.

[0038] The number of the material receiving pipes 7 determines the types of raw materials added, and can therefore be set as required.

[0039] It should be noted that the device is also provided with a feeding device and a scraper (not shown in the figure).

[0040] The inner surface of the annular groove 31 is slidably connected to the outer surface of the annular rod 32, and the annular rod 32 and the annular groove 31 correspond to each other and the annular rod 32 supports the annular groove 31. Since the outer surface of the annular rod 32 and the inner surface of the annular groove 31 are designed to fit together, lubricant should be added to prevent wear between the annular rod 32 and the annular groove 31 and reduce friction resistance. The lower surface of the annular rod 32 is welded and fixed to the outer side of the upper surface of the fixing seat 34.

[0041] Specifically, the lower surface of the spring 8 is welded and fixed to one side of the upper surface of the mixing barrel 1, and the upper surface of the spring 8 is welded and fixed to the lower surface of the pressure plate 9, one side surface of the pressure plate 9 is welded and fixed to one side of the outer surface of the material receiving pipe 7, and the two sides of the upper inner wall of the inner cavity of the material receiving pipe 7 are welded and fixed to the two end surfaces of the push rod 4, which is used to lift the round plastic plug 5 when the upper opening of the material receiving pipe 7 is docked and limited with the lower opening of the material receiving barrel 12.

A motor is arranged at the lower part of the mixing barrel 1, and a stirring blade 13 is rotatably arranged in the middle of the inner cavity of the mixing barrel 1. The motor and the stirring blade 13 constitute a stirring mechanism. Since the stirring mechanism is an existing and mature technology, it will not be described in detail. The output end of the motor is fixedly connected to the lower end of the stirring blade 13. At the same time, a discharge port 14 is penetrated through the outer wall on one side of the lower surface of the mixing barrel 1, and the stirring blade 13 stirs the material evenly and then discharges the evenly stirred material through the discharge port 14.

[0043] The servo motor 35, the mixing barrel 1, the mixing blade 13, and the motor at the bottom of the mixing barrel 1 in the present device are all prior art, and their structural principles are not described in detail here. In practical applications, the compiler sets the speed by receiving external command signals, such as signals from PLC or other automation equipment. Since the compiler is prior art, it is not described in detail here.

[0044] Principle and process of this utility model:

[0045] Under normal circumstances, the staff will load the materials to be mixed into the material receiving barrel 12 according to the proportion and group them, and then turn on the servo motor 35 controller to make the servo motor 35 work according to the set program. When the output end of the servo motor 35 rotates, the gear ring 36 is driven to rotate, thereby driving the turntable 33 and the longitudinal rotating rod 66 to rotate, and the material receiving barrel 12 on the turntable 33 rotates together with the turntable 33, and the collected materials are rotated to the receiving pipe 7;

[0046] At the same time, the longitudinal rotating rod 66 fixed at the middle of the turntable 33 rotates to drive the first bevel gear 61 to rotate, and the first bevel gear 61 rotates to drive the second bevel gear 65 to rotate, thereby driving the cam 62 to rotate, so that the protruding end of the cam 62 leaves the upper surface of the pressing plate 9 by rotating, and the pressing plate 9 loses the downward pressure of the cam 62, and the rebound force of the spring 8 fixed on the lower surface makes a linear motion upward, and drives the material receiving pipe 7 to move upward, so that the upper opening of the material receiving pipe 7 is stuck to the bottom opening of the material receiving barrel 12 for limiting. At the same time, when the material receiving pipe 7 moves upward, the internal push rod 4 will push out the round plastic plug 5 at the lower opening of the material receiving barrel 12, so that the material inside the material receiving barrel 12 is transported to the inside of the mixing barrel 1 through the material receiving pipe 7;

[0047] At the same time, the motor at the bottom of the mixing barrel 1 works, driving the mixing blades 13 to mix the materials. When the materials are mixed evenly, they are discharged through the discharge port 14 on the side of the mixing barrel 1.

[0048] At this time, the first group of materials is put in, and the protruding end of the cam 62 rotates one circle to press the pressing plate 9 down. The pressing plate 9 drives the material receiving pipe 7 to move downward, so that the turntable 33 rotates to put in the next group of materials.

[0049] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
