[0036] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] Please refer to Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a raw material premixing device in a composite material preparation process, comprising: a mixing tank 1 for mixing raw materials for composite material preparation, a feeding channel 101 for weighing raw materials is provided on the top of the mixing tank 1, a discharge pipe 102 is installed on the bottom of the side of the mixing tank 1, a preliminary mixing component 103 for preliminary mixing of raw materials is installed inside the mixing tank 1 and at the position corresponding to the feeding channel 101, and a stirring component 105 for mixing raw materials is also installed inside the mixing tank 1;

[0038] By adopting the above technical solution, not only can the metering component 1011 accurately measure the raw materials, thereby ensuring the accuracy of raw material mixing, but also when the raw materials are put into the mixing tank 1, they are first mixed by the preliminary mixing component 103, and then stirred again by the stirring component 105, thereby ensuring the uniformity of raw material mixing and thus ensuring the mixing quality of raw materials.

[0039] Please refer to Figures 1 to 4 As shown, a metering component 1011 that can be flipped for feeding is installed inside the feeding channel 101.

[0040] The metering component 1011 includes a servo motor 10111 fixedly connected to the side of the feeding channel 101. A flap 10112 is fixedly connected to the output shaft of the servo motor 10111. An installation groove 10113 is provided on the top of the flap 10112. A force plate 10114 is slidably connected to the inner wall of the installation groove 10113. Connecting springs 10115 are fixedly connected to both sides of the bottom of the force plate 10114. The other end of the connecting spring 10115 is fixedly connected to the bottom of the inner wall of the installation groove 10113.

[0041] A pressure sensor 10116 is installed at the center of the bottom of the inner wall of the mounting groove 10113, corresponding to the position of the force plate 10114. When the material is fed through the feeding channel 101, the material falls onto the force plate 10114 and squeezes the pressure sensor 10116. The pressure signal generated by the pressure sensor 10116 is transmitted to the external controller. When the preset value is reached, the controller controls the servo motor 10111 to operate and drives the flip plate 10112 to flip, so that the fed material can be accurately measured and fed.

[0042] Among them, the pressure sensor 10116 can be selected as the BECK pressure sensor 901.11121M4, which has high accuracy and stability. The controller can be selected as the S7-200 ultra-miniature PLC controller, which can meet the usage requirements of this embodiment.

[0043] Please refer to Figures 1 to 4 As shown, a feed plate 1021 is installed at the bottom of the inner wall of the mixing tank 1 and at the position corresponding to the discharge pipe 102.

[0044] A vibration motor 1022 is installed at the bottom of the mixing tank 1, corresponding to the position of the feed plate 1021. By setting the feed plate 1021 and the vibration motor 1022, the discharge of the mixed raw materials through the discharge pipe 102 is made more convenient and thorough.

[0045] Please refer to Figures 1 to 4 As shown, the preliminary mixing component 103 includes a first stirring motor 1031 fixedly connected to the side of the mixing tank 1. A spiral blade 1032 is installed on the output shaft of the first stirring motor 1031. A guide plate 104 is installed on the inner wall of the mixing tank 1 at the position corresponding to the spiral blade 1032. A discharge port 1041 is opened on the guide plate 104. The first stirring motor 1031 drives the spiral blade 1032 to rotate and stirs and conveys the raw materials to the upper left, so that the raw materials can be uniformly mixed under the cooperation of the guide plate 104.

[0046] Please refer to Figures 1 to 4 As shown, a sealing seat 10311 is installed on the side of the mixing tank 1 at the position corresponding to the first stirring motor 1031. By setting the sealing seat 10311, the sealing performance between the first stirring motor 1031 and the mixing tank 1 is increased when the first stirring motor 1031 rotates.

[0047] Please refer to Figures 1 to 4 As shown, the stirring assembly 105 includes a second stirring motor 1051 fixedly connected to the side of the mixing tank 1. A stirring shaft 1052 is fixedly connected to the output shaft of the second stirring motor 1051. A stirring blade 1053 is fixedly connected to the stirring shaft 1052. The stirring shaft 1052 is driven to rotate by the second stirring motor 1051, so that the raw materials can be stirred again by the stirring blade 1 and the mixing tank 1053.

[0048] The working principle of this utility model is as follows: When the material is fed through the feeding channel 101, it falls onto the force plate 10114 and squeezes the pressure sensor 10116. The pressure signal generated by the pressure sensor 10116 is transmitted to the external controller. When the preset value is reached, the controller controls the servo motor 10111 to operate and drives the flip plate 10112 to flip, thereby accurately measuring and feeding the material, thus ensuring the accuracy of raw material mixing. Moreover, when the raw material is fed into the mixing tank 1, the first stirring motor 1031 drives the spiral blade 1032 to rotate and stirs and conveys the fed material to the upper left. With the cooperation of the guide plate 104, the raw material is evenly mixed. Then, the second stirring motor 1051 drives the stirring shaft 1052 to rotate, so that the mixing tank 1053 can stir the raw material again through the stirring blades, thereby ensuring the uniformity of raw material mixing and thus ensuring the mixing quality of raw materials.
