[0027] Embodiment 1:

[0028] like Figures 1 to 6 As shown, the utility model is a mixing device for modified material production, comprising: a stirring tank 1, a feeding hopper, a stirring mechanism for stirring raw materials, and a discharging mechanism for quickly discharging the uniformly stirred raw materials;

[0029] Raw materials are added into the inner cavity of the stirring tank 1 through the feed hopper, the raw materials can be evenly stirred by the stirring mechanism, and the evenly stirred raw materials can be quickly discharged by the discharging mechanism.

[0030] The stirring mechanism comprises: a rotating shaft rotatably mounted at the top center of the stirring tank 1, a motor 2 fixedly mounted at the top of the rotating shaft, a circular plate 5 fixedly sleeved on the outer edge of the rotating shaft, a linkage shaft rotatably mounted at the bottom of the circular plate 5, a stirring blade 7 fixedly mounted on the outer edge of the linkage shaft, a linkage gear 6 fixedly sleeved on the outer edge of the linkage shaft, a gear ring 8 meshingly mounted on the outer edge of the linkage gear 6, and a turning component for turning the raw materials up and down;

[0031] By starting the motor 2, the power output shaft of the motor 2 drives the rotating shaft to rotate, the rotating shaft drives the circular plate 5 to rotate, and the circular plate 5 drives a plurality of linkage shafts to rotate, and the plurality of linkage shafts are evenly distributed at the bottom of the circular plate 5 in a ring shape, and the linkage shaft drives the linkage gear 6 and the stirring blade 7 to rotate. Since the linkage gear 6 and the gear ring 8 are meshed with each other, the linkage gear 6 rotates while revolving around the rotating shaft, so that the stirring blade 7 can rotate while revolving. Through the revolution of the plurality of stirring blades 7, the raw materials in the stirring tank 1 can be evenly distributed, which helps the raw materials move to the best mixing position, promotes the distribution of the raw materials, makes the mixing more uniform, and can drive the raw materials to mix, thereby improving the mixing efficiency and achieving the preliminary mixing of the raw materials.

[0032] Through the self-rotation of the plurality of stirring blades 7, the stirring blades 7 can fully contact and act on the raw materials during the movement, thereby avoiding partial excessive or insufficient mixing of the raw materials, thereby ensuring a more uniform mixing effect and further improving the mixing efficiency;

[0033] As can be seen from the above, through the revolution and rotation of the plurality of stirring blades 7, high efficiency and uniformity of the mixed materials are achieved, and the raw materials can be mixed more quickly and more comprehensively.

[0035] The spiral blade 3 and the scraper 4 are driven to rotate by the rotating shaft, and the raw materials can be turned from bottom to top by the rotation of the spiral blade 3. In actual use, the raw materials can be turned from bottom to top by the spiral blade 3, so that secondary mixing of the raw materials can be achieved, further improving the mixing effect;

[0036] Moreover, when the motor 2 rotates in the reverse direction, the spiral blade 3 can drive the raw material to move from top to bottom, so that the raw material actively moves to the discharge pipe, achieving the purpose of rapid discharge, and avoiding blockage at the discharge pipe; since the motor 2 is located above the discharge pipe, it is convenient to turn the raw material at the discharge pipe from bottom to top when the spiral blade 3 rotates forward; when the spiral blade 3 rotates in the reverse direction, it drives the raw material to move from top to bottom for rapid discharge, avoiding blockage;

[0037] During the mixing process, the raw materials attached to the inner wall of the mixing tank 1 can be scraped off by the rotation of the scraper 4, so that the raw materials can be better mixed, and during the discharging process, the raw materials attached to the inner wall of the mixing tank 1 can be scraped off again to avoid raw material residue and improve the discharging effect;

[0038] Through the cooperation of the stirring blade 7, the spiral blade 3 and the scraper 4, during the mixing process, the raw materials are fully stirred while being turned from bottom to top, so that the raw materials at the bottom and the top of the stirring tank 1 are fully mixed, thereby improving the mixing effect. At the same time, during the discharging process, raw material residue is avoided, thereby improving the discharging effect.

[0039] The discharging mechanism includes: a collecting seat 9 fixedly installed at the bottom of the inner cavity of the mixing tank 1, the top of the collecting seat is designed to be arc-shaped downward, so that the raw materials can easily move to the discharging pipe, and the scraper 4 and the collecting seat 9 are arranged to fit each other, a discharging pipe plugged and installed at the collecting seat 9 and the bottom of the mixing tank 1, an electromagnetic valve installed on the discharging pipe, and a vibration component for vibrating the discharging pipe to discharge the material, and the vibration component includes: a rotating rod rotatably installed at the bottom of the mixing tank 1, a transmission bevel gear 16 and a rotating plate 17 fixedly sleeved on the outer edge of the rotating rod, a flexible belt 18 fixedly installed on the outer edge of the rotating plate 17, and a belt A linkage unit for rotating the flexible belt 18, the linkage unit comprising: a driving bevel gear 10 fixedly sleeved on the outer edge of the rotating shaft, a driven bevel gear 11 meshingly mounted on the outer side of the driving bevel gear 10, a long shaft fixedly mounted on one side of the driven bevel gear 11, a driving pulley 12 fixedly mounted on one end of the long shaft, a linkage bevel gear 15 meshingly mounted on the outer side of the transmission bevel gear 16, a transmission shaft fixedly mounted on one side of the linkage bevel gear 15, a driven pulley 14 fixedly mounted on one end of the transmission shaft, and a linkage belt 13 installed between the driving pulley 12 and the driven pulley 14;

[0040] The active bevel gear 10 is driven to rotate by the rotating shaft, and the driven bevel gear 11 is driven to rotate by the active bevel gear 10, so that the active pulley 12 can be driven to rotate, and the interlocking belt 13 is driven to rotate by the active pulley 12, and the driven pulley 14 is driven to rotate by the interlocking belt 13, so that the interlocking bevel gear 15 can be driven to rotate, and the transmission bevel gear 16 is driven to rotate by the interlocking bevel gear 15, so that the rotating plate 17 can be driven to rotate, and the flexible belt 18 is driven to rotate by the rotating plate 17. The rotation of the flexible belt 18 can hit the discharge pipe, so that the discharge pipe vibrates, thereby further avoiding the blockage of the raw materials in the inner cavity of the discharge pipe and improving the discharge efficiency;

[0041] Through the cooperation between the flexible belt 18, the spiral blade 3 and the scraper 4, the raw materials can be actively moved to the discharge pipe during discharge, so as to achieve the purpose of rapid discharge, avoid blockage at the discharge pipe and improve the discharge efficiency;

[0042] It is added here that the flexible belt 18 is made of a flexible material, and when the discharge pipe is hit, no damage is caused to the outer side of the discharge pipe. The flexible belt 18 can preferably be made of rubber.

[0043] A timer is installed on the outside of the mixing tank 1, and a PLC controller electrically connected to the timer is installed on the outside of the mixing tank 1. The PLC controller is electrically connected to the motor 2 and the solenoid valve;

[0044] The mixing time and discharging time can be set by the timer, and the PLC controller controls the running status of the motor 2 and the solenoid valve according to the set time.

At the same time, the PLC controller starts the timer to count;

[0049] Step S3: When the timer reaches the set mixing time T1, the PLC controller controls the motor 2 to change its rotation direction, thereby driving the spiral blade 3 and the scraper 4 to rotate in the opposite direction, and at the same time driving the flexible belt 18 to slap and vibrate the discharge pipe, so that the raw materials can be moved from top to bottom, so that the raw materials actively move to the discharge pipe, achieving the purpose of rapid discharge, and avoiding blockage at the discharge pipe. At the same time, the PLC controller controls the solenoid valve to open, and the mixed raw materials are discharged;

[0050] Step S4: When the timer reaches the set discharging time T2, the discharging is completed.
