[0024] Further, the connecting structure includes a fixing plate 56, which is fixedly connected to the left and right sides of the top of the outer wall of the mixing bin 55, and a plug plate 57 is fixedly connected to the top of the fixing plate 56, and the plug plate 57 is inserted into the inside of the connecting seat 58. A movable cavity 59 is opened on one side of the plug plate 57, and a first spring 60 is arranged inside the movable cavity 59, and one side of a fixing block 61 is also sleeved inside the movable cavity 59, and the other side of the fixing block 61 is engaged with a fixing groove 62, and the fixing groove 62 is opened on the inner wall of the slide groove 68, and a push plate 63 is also inserted inside the fixing groove 62, and a pressing plate 64 is fixedly connected to the top of the push plate 63. The pressing plate 64 is fixedly connected to the left and right sides of the bottom end of the outer wall of the intermediate bin 39, and the front and rear sides of the top of the connecting seat 58 are fixedly connected with guide rods 65, and the guide rods 65 are slidably connected to the pressing plates 64, and the outer side of the guide rods 65 is wound with a second spring 66; During operation, when the chemical raw materials are stirred, the chemical raw materials to be stirred are first poured into the mixing bin 55, and then the plug plate 57 is aligned with the connecting seat 58, and then the mixing bin 55 is pushed upward to insert the plug block 54 into the socket 53, and the plug plate 57 is inserted into the connecting seat 58. When the plug plate 57 is inserted into the connecting seat 58, the inner wall of the connecting seat 58 squeezes the inclined surface on the fixed block 61, so that the fixed block 61 moves toward the inside of the active cavity 59 under the action of the squeezing force, and squeezes the first spring 60 to cause the first spring 60 to produce elastic deformation. When the plug block 54 is fully inserted into the socket 53, the plug plate 57 is also fully inserted into the connecting seat 58. At this time The inner wall of the connecting seat 58 no longer squeezes the fixing block 61. At this time, the fixing block 61 returns to its original position under the restoring force of the first spring 60, and is inserted into the fixing groove 62 and engages with the fixing groove 62 to connect the mixing chamber 55 with the intermediate chamber 39. When the mixing is completed and the mixing chamber 55 needs to be removed, it is only necessary to press the pressing plate 64 downward to move the pushing plate 63 fixedly connected to the pressing plate 64 downward and push the fixing block 61 so that the fixing block 61 enters the movable cavity 59 and releases the engagement with the fixing groove 62. At this time, the mixing chamber 55 is pulled downward to disengage the plug plate 57 from the inside of the connecting seat 58, and the plug block 54 is disengaged from the inside of the socket 53 to remove the mixing chamber 55.

[0025] Further, the side of the first spring 60 close to the fixed block 61 is fixedly connected to the fixed block 61, and the side of the first spring 60 away from the fixed block 61 is fixedly connected to the inner wall of the movable cavity 59, and the side of the fixed block 61 away from the first spring 60 is provided with an inclined surface, the top end of the second spring 66 is fixedly connected to the bottom end of the pressing plate 64, and the bottom end of the second spring 66 is fixedly connected to the top end of the connecting seat 58; the bottom end of the fixed block 61 close to the first spring 60 is connected to a slider 67, and the slider 67 is slidably connected to the inside of the slide groove 68, and the slide groove 68 is provided at the bottom end of the movable cavity 59; During operation, the slider 67 and the slide groove 68 cooperate to limit the movement of the fixed block 61 , thereby preventing the fixed block 61 from moving excessively and escaping from the inside of the movable cavity 59 .

[0026] Furthermore, the auxiliary stirring structure includes a wave plate 69, which is fixedly connected to the inner wall of the mixing bin 55, and a connecting shaft 70 is fixedly connected to the center of the bottom end of the inner wall of the mixing bin 55. An auxiliary stirring paddle 71 is fixedly connected to the outer side of the connecting shaft 70, and the auxiliary stirring paddle 71 is designed in a strip-shaped blade shape, and the end of the auxiliary stirring paddle 71 away from the connecting shaft 70 is designed to be first concave inward and then gradually convex outward. A guide ring 72 is fixedly connected to the bottom end of the inner wall of the intermediate bin 39, and the guide ring 72 is designed in an annular shape as a whole, and the cross section of the guide ring 72 is designed in an inverted U shape. During operation, the driving gear 31 drives the driven gear 32 to rotate, and synchronously drives the first gear ring 38 to rotate. The rotation of the first gear ring 38 drives the fixedly connected intermediate bin 39 to rotate synchronously. When the intermediate bin 39 rotates, the mixing bin 55 is also driven to rotate synchronously through the connection structure. The centrifugal force of the mixing bin 55 during rotation causes the chemical raw materials to flow to the inner wall of the mixing bin 55. The chemical raw materials flowing thereon are splashed out through the wave plate 69 fixedly connected to the inner wall of the mixing bin 55 and then mixed with other chemical raw materials. When the rotation speed is fast, The chemical raw materials flow upward along the inner wall of the mixing bin 55 and contact the guide ring 72. The guide ring 72 guides the flow direction of the chemical raw materials, so that the chemical raw materials return to the inside of the mixing bin 55 along the guide ring 72 to mix with the chemical raw materials originally at the bottom of the mixing bin 55. At the same time, when the mixing bin 55 rotates, the auxiliary stirring paddle 71 is driven to rotate synchronously through the connecting shaft 70. The auxiliary stirring paddle 71 throws the chemical raw materials toward the inner wall of the mixing bin 55 and hits the wave plate 69, so that the chemical raw materials are dispersed and mixed by the impact.

[0027] Working principle: When the chemical raw materials are stirred, first pour the chemical raw materials to be stirred into the mixing bin 55, then align the plug plate 57 with the connecting seat 58, and then push the mixing bin 55 upward to insert the plug block 54 into the socket 53, and insert the plug plate 57 into the connecting seat 58. When the plug plate 57 is inserted into the connecting seat 58, the inner wall of the connecting seat 58 squeezes the inclined surface on the fixed block 61, so that the fixed block 61 moves toward the inside of the active cavity 59 under the action of the squeezing force, and squeezes the first spring 60 to cause the first spring 60 to produce elastic deformation. When the plug block 54 is fully inserted into the socket 53, the plug plate 57 is also fully inserted into the connecting seat 58. When the mixing chamber 55 is removed, the inner wall of the connecting seat 58 no longer squeezes the fixing block 61. At this time, the fixing block 61 returns to its original position under the restoring force of the first spring 60, and is inserted into the fixing groove 62 and engaged with the fixing groove 62, so that the mixing chamber 55 is connected to the intermediate chamber 39. When the mixing is completed and the mixing chamber 55 needs to be removed, the pressing plate 64 needs to be pressed downward to move the pushing plate 63 fixedly connected to the pressing plate 64 downward and push the fixing block 61 so that the fixing block 61 enters the movable cavity 59 and releases the engagement with the fixing groove 62. At this time, the mixing chamber 55 is pulled downward to disengage the plug plate 57 from the inside of the connecting seat 58, and the plug block 54 is disengaged from the inside of the socket 53 to remove the mixing chamber 55.

[0028] When the motor 1 is started, it drives the driving gear 31 to rotate, and the driving gear 31 rotates to drive the driven gear 32 to rotate, and the driven gear 32 drives the driving rod 33 to rotate synchronously, and the driving rod 33 drives the rack 34 to periodically reciprocate to make the driven gear 35 rotate periodically forward and reverse, and the driven gear 35 rotates to drive the first fixed rotating frame 42 to rotate synchronously, so that the rotating rod 43 rotatably connected to the first rotating frame 42 drives the first stirring paddle 44 to rotate synchronously, and the first rotating frame 42 drives the fixedly connected first bevel gear 47 to rotate synchronously when rotating, and the first bevel gear 47 drives the third bevel gear 49 to rotate in the opposite direction through the second bevel gear 48 when rotating, so that the second rotating frame 51 fixedly connected to the third bevel gear 49 drives the second stirring paddle 52 to rotate synchronously, and the chemical raw materials are stirred by the cooperation between the first stirring paddle 44 and the second stirring paddle 52.

[0029] When the rotating rod 43 revolves with the rotation of the first rotating frame 42, the planetary gear 45 fixedly connected to its top end rotates synchronously with the second ring gear 46, so that the rotating rod 43 and the first stirring paddle 44 fixedly connected thereto rotate synchronously, thereby further stirring the chemical raw materials.

[0030] When the driving gear 31 drives the driven gear 32 to rotate, it synchronously drives the first gear ring 38 to rotate. The rotation of the first gear ring 38 drives the fixedly connected intermediate bin 39 to rotate synchronously. When the intermediate bin 39 rotates, the mixing bin 55 is also driven to rotate synchronously through the connection structure. The centrifugal force of the mixing bin 55 during rotation causes the chemical raw materials to flow to the inner wall of the mixing bin 55. The chemical raw materials flowing thereon are splashed out through the wave plate 69 fixedly connected to the inner wall of the mixing bin 55 and then mixed with other chemical raw materials. When the rotation speed is fast, the chemical raw materials flow to the inner wall of the mixing bin 55. The chemical raw material flows upward along the inner wall of the mixing bin 55 and contacts the guide ring 72. The guide ring 72 guides the flow direction of the chemical raw material, so that the chemical raw material returns downward along the guide ring 72 to the inside of the mixing bin 55 and mixes with the chemical raw material originally at the bottom of the mixing bin 55. At the same time, when the mixing bin 55 rotates, the auxiliary stirring paddle 71 is driven to rotate synchronously through the connecting shaft 70. The auxiliary stirring paddle 71 is used to throw the chemical raw material toward the inner wall of the mixing bin 55 and hit the wave plate 69, so that the chemical raw material is dispersed and mixed by the impact.
