[0002] Concrete admixtures are chemical substances added during the mixing of concrete, accounting for less than 5% of the cement mass, which can significantly improve the performance of concrete. The characteristics of concrete admixtures are that they are of many varieties and small dosage, have a great influence on the performance of concrete, have the characteristics of low investment, quick effect, and significant technical and economic benefits. With the continuous advancement of science and technology, admixtures have been increasingly used, and admixtures have become the fifth important component of concrete in addition to the four basic components.

[0003] An automatic production system for admixtures disclosed in the Chinese utility model patent application disclosure CN213160656U, although the equipment abandons manual batching and relies on the speed ratio to control the speed of the paddle to introduce raw materials, thereby controlling the injection ratio of raw materials, which not only liberates manpower, but also avoids the problem of batching errors caused by staff fatigue. However, in the process of raw material feeding, the raw materials may slide down too fast in the feed trough, resulting in the same amount of raw materials driven by each rotation of the paddle, affecting the proportion of the ratio, and has the disadvantage of poor accuracy. In addition, the raw materials may also be blocked in the feed trough, which has the disadvantage of easy blockage. Utility Model Content

[0014] The utility model provides an automatic production system for admixtures, which has the following beneficial effects:

[0015] 1. This kind of automatic production system of additives has the effect of improving the accuracy of proportioning through the setting of a feeding pipe, a vibration plate and a spiral blade. When in use, the staff can increase the number of feeding hoppers by themselves according to the number of raw material types. An additive is set in a lifting feeding hopper, and various raw materials are set in another feeding hopper. According to the mixing ratio, the speed of the corresponding servo motor is controlled by a controller. In the feeding process, the raw material or additive enters the feeding pipe in the feeding hopper, enters the feeding hopper through the feeding pipe, and finally enters the feeding channel. When the raw material enters the feeding hopper from the feeding pipe, the feeding hopper is provided with sufficient additives or raw materials. The additives or raw materials enter the feeding pipe under the action of gravity. At this time, the first motor is turned on, and the cam is driven to rotate by the first motor. Since the cam is in contact with the lower surface of the vibration plate, as the cam rotates, the vibration plate rotates on the surface of the rotating rod, and then the additive or raw material entering the feeding pipe is vibrated. Through vibration, Avoid the agglomeration or clogging of the additive at this point, keep the additive or raw material in the discharge pipe in a flowing state, and achieve more uniform discharge. At the same time, cooperate with the servo motor to drive the rotation of the spiral shaft and the spiral blade, so that the additive or raw material enters the middle of the spiral blade, and the additive or raw material is sent to the other end of the feeding channel through the spiral blade, and the additive or raw material is discharged into the mixing channel. At this time, the second motor drives the rotating shaft and the stirring rod to rotate, and the additives or raw materials entering the mixing channel from multiple ports are stirred to mix the additives and raw materials together. After the mixing is completed, they are discharged outward at the discharge valve to complete the mixing of the raw materials and additives. According to the mixing ratio, the speed of the corresponding servo motor is controlled by the controller. By reducing the speed of the servo motor, the amount of the corresponding additive or raw material can be reduced, which plays a role in facilitating the control of the mixing ratio. Through the vibration at the vibration plate, the blockage of the raw material or additive is avoided. At the same time, the discharge at the discharge pipe is more uniform, thereby achieving the purpose of improving the accuracy of the ratio. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to achieve the purpose of improving the accuracy of the ratio, when in use, according to the number of raw material types, the staff can increase the number of lower hoppers 3 by themselves. An additive is set in one lower hopper 3 of the lifting, and various raw materials are set in the other lower hoppers 3. According to the mixing ratio, the speed of the corresponding servo motor 12 is controlled by the controller. During the feeding process, the raw material or additive enters the lower hopper 3 into the lower pipe 2, enters the feed hopper 10 through the lower pipe 2, and finally enters the feeding channel 8.
