DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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] Specific examples are given below.

[0024] like Figures 1 to 3As shown, a kneading machine stirring device described in an embodiment of the utility model comprises a bottom support 1; a kneading tank 2 is installed on the top of the bottom support 1; two stirring blades 3 are rotatably connected inside the kneading tank 2, and a first synchronous wheel 6 is fixedly connected to the end of the rotating shaft of one of the stirring blades 3; a driving gear 4 is fixedly connected to the end of the stirring blade 3 away from the first synchronous wheel 6; two kneading gears 5 are rotatably connected inside the kneading tank 2, and the two kneading gears 5 are meshed, and the kneading gears 5 are respectively meshed with a driving gear 4; a processing tank 9 is fixedly connected inside the kneading tank 2; a rotating shaft 10 is rotatably connected inside the processing tank 9; a second synchronous wheel 7 is fixedly connected to the end of the rotating shaft 10; a synchronous belt 8 is connected between the first synchronous wheel 6 and the second synchronous wheel 7; a pushing auger 11 is fixedly connected to the rotating shaft 10; a cutting net 12 is fixedly connected to the end of the processing tank 9, and the cutting net 12 is provided It is placed at one end of the processing tank 9 close to the inside of the kneading tank 2; a fixing frame 13 is fixedly connected to the side wall of the kneading tank 2; a driving motor is fixedly connected to the side wall of the fixing frame 13; the output end of the driving motor is connected to the rotating shaft 10; during operation, when it is necessary to stir the material, the rotating shaft 10 can be driven to rotate by the driving motor, and then the first synchronous wheel 6 can be driven to rotate through the synchronous belt 8, and then the two stirring blades 3 are driven to rotate in the opposite direction through the cooperation of the driving gear 4 and the kneading gear 5, so as to knead and stir the material inside the kneading tank 2, and at the same time, when it is necessary to put the material into the inside of the kneading tank 2, the material can be put into the inside of the processing tank 9, and under the rotation of the rotating shaft 10, the material can be pushed to the cutting net 12 by pushing the auger 11, and then under the cutting action of the cutting net 12, the material is cut, so that the material entering the inside of the kneading tank 2 can be made more finely broken, so that the kneading and stirring effect of the material is better.

[0025] like Figure 3 to Figure 4 As shown, a magnetic coupler 14 is fixedly connected to the end of the rotating shaft of the stirring blade 3; a magnetic coupler 14 is fixedly connected to the side wall of the first synchronous wheel 6, and the two magnetic couplers 14 are arranged correspondingly; when working, when the stirring blade 3 is driven to rotate by the first synchronous wheel 6, the stirring blade 3 can be driven to rotate by the magnetic force of the magnetic coupler 14. When the resistance of the stirring blade 3 is too large, the two magnetic couplers 14 will be disengaged, thereby effectively avoiding the situation where the resistance of the stirring blade 3 is too large, which is easy to cause damage to the drive motor.

[0026] like Figure 1 to Figure 2 As shown, an anti-overflow plate 15 is fixedly connected to the top of the processing tank 9; the anti-overflow plate 15 is arranged at a position corresponding to the top of the pushing auger 11; during operation, when the material is transported by pushing the auger 11, by arranging the anti-overflow plate 15 on the top of the processing tank 9, the overflow of the material can be effectively avoided, so that the pushing auger 11 is more stable when transporting the material.

[0027] like Figure 5 As shown, a plurality of anti-skid protrusions 16 are fixedly connected to the side walls of the first synchronous wheel 6 and the second synchronous wheel 7, and the anti-skid protrusions 16 are regularly arranged in a circular array on the side walls of the first synchronous wheel 6 and the second synchronous wheel 7; during operation, when the first synchronous wheel 6 and the second synchronous wheel 7 are transmitted by the synchronous belt 8, by providing the anti-skid protrusions 16 on the first synchronous wheel 6 and the second synchronous wheel 7, the friction between the synchronous belt 8 and the first synchronous wheel 6 and the second synchronous wheel 7 can be increased, so that the synchronous belt 8 is more stable when transmitting the first synchronous wheel 6 and the second synchronous wheel 7.

[0028] like Figure 5 As shown, a positioning block 17 is fixedly connected to the side wall of the rotating shaft 10; the positioning block 17 is rotatably connected to the internal position of the kneading groove 2; during operation, when the rotating shaft 10 rotates inside the processing groove 9, by arranging the positioning block 17 on the rotating shaft 10 and limiting the rotation of the positioning block 17 through the kneading groove 2, the rotating shaft 10 can be less inclined during rotation, making the rotating shaft 10 more stable during rotation.

[0029] like Figure 5 As shown, an anti-wear ball 18 is provided between the kneading groove 2 and the positioning block 17; the side wall of the anti-wear ball 18 is in contact with the side walls of the kneading groove 2 and the positioning block 17; during operation, when the positioning block 17 rotates inside the kneading groove 2, by providing the anti-wear ball 18 between the kneading groove 2 and the positioning block 17, the sliding friction between the kneading groove 2 and the positioning block 17 can be converted into rolling friction, so that the friction force between the kneading groove 2 and the positioning block 17 is smaller, thereby reducing the wear between the kneading groove 2 and the positioning block 17.

[0030] During operation, when it is necessary to stir the material, the driving motor can be used to drive the rotating shaft 10 to rotate, and then the synchronous belt 8 can be used to drive the first synchronous wheel 6 to rotate, and then the driving gear 4 and the kneading gear 5 can be used to drive the two stirring blades 3 to rotate in the opposite direction, so as to knead and stir the material inside the kneading tank 2. At the same time, when it is necessary to put the material into the kneading tank 2, the material can be put into the processing tank 9. Under the rotation of the rotating shaft 10, the material can be pushed toward the cutting net 12 by pushing the auger 11, and then the material can be cut under the cutting action of the cutting net 12, so that the material entering the kneading tank 2 can be more finely crushed, so that the kneading and stirring effect of the material is better.

[0031] When the stirring blade 3 is driven to rotate by the first synchronous wheel 6, the stirring blade 3 can be driven to rotate by the magnetic force of the magnetic coupler 14. When the stirring blade 3 is subjected to too much resistance, the two magnetic couplers 14 will disengage, thereby effectively avoiding the situation where the stirring blade 3 is subjected to too much resistance and easily causes damage to the drive motor.

[0032] When the material is transported by pushing the auger 11, an anti-overflow plate 15 is provided on the top of the processing tank 9, which can effectively prevent the material from overflowing, making the auger 11 more stable when transporting the material.

[0033] When the first synchronous wheel 6 and the second synchronous wheel 7 are transmitted by the synchronous belt 8, by setting anti-slip bumps 16 on the first synchronous wheel 6 and the second synchronous wheel 7, the friction between the synchronous belt 8 and the first synchronous wheel 6 and the second synchronous wheel 7 can be made greater, so that the synchronous belt 8 can be more stable when transmitting the first synchronous wheel 6 and the second synchronous wheel 7.

[0034] When the rotating shaft 10 rotates inside the processing tank 9, by setting a positioning block 17 on the rotating shaft 10 and limiting the rotation of the positioning block 17 through the kneading groove 2, the rotating shaft 10 can be less likely to tilt during rotation, making the rotating shaft 10 more stable during rotation.

[0035] When the positioning block 17 rotates inside the kneading groove 2, by arranging the anti-wear ball 18 between the kneading groove 2 and the positioning block 17, the sliding friction between the kneading groove 2 and the positioning block 17 can be changed into rolling friction, so that the friction force between the kneading groove 2 and the positioning block 17 is smaller, thereby reducing the wear between the kneading groove 2 and the positioning block 17.
