[0002] Rock wool is an excellent thermal insulation material with heat preservation, heat insulation and sound insulation functions. It is mainly made of natural basalt and other mineral fibers as the main raw materials. It is made into rock wool board through high-temperature melting, fiber spraying and curing processes. In the process of producing rock wool, the density of rock wool is one of the important parameters affecting its performance. Different products have different density requirements. The density of general products is controlled at 60-200kg / m 3 between.

[0003] During the production process, the control of rock wool density needs to take into account many factors, such as raw material composition, process flow, production equipment, etc., among which the ratio of raw materials added during rock wool manufacturing is particularly important.

The left and right inner walls of the material removal chute 91 are connected with a rotating plate 92 by rotating the second shaft. The rock wool raw material is dialed by the rotation of the rotating plate 92, so that the excess rock wool raw material is removed from the material removal chute 91. When there is more excess raw material, the upper material removal chute 91 is used to remove the larger raw material. When there is less excess raw material, the lower material removal chute 91 is used to remove the smaller raw material. The material removal is more accurate, and the ratio between the rock wool raw materials is more accurate. The material removal mechanism 9 also includes a turntable 95, a boss 96 and a support plate 99. The turntable 95 is respectively connected to the second shaft by rotating the third shaft.

After the weighing frame plate 5 stops moving, the left and right positions of the weighing frame plate 5 are determined by the change in the rotation angle of the turntable 95, so that the discharge hole of the weighing frame plate 5 is opened. The unloading hole of the weighing slide 3 corresponds vertically to the unloading hole of the weighing slide 3, which is convenient for subsequent unloading. The unloading mechanism 9 also includes a motor 1 93 and a motor 2 94. The motor 1 93 is respectively arranged on the right side of the weighing frame plate 5.

The end of the spring 98 close to the weighing frame plate 5 is fixedly connected to the outer arc surface of the slide post 97, and the end of the spring 98 away from the weighing frame plate 5 is fixedly connected to the inner wall of the slide 2. The left and right movement of the weighing frame plate 5 will overcome the elastic force of the spring 98 to push the slide post 97 to slide. Under the action of the elastic force of the spring 98, the movement process of the weighing frame plate 5 is more stable. The left and right sides of the rock wool raw material hopper 1 are provided with a protective shell 15, and the motor 2 94 and the slide post 97 are respectively located inside the protective shell 15 to hide the motor 2 94.

[0031] The working principle of the unloading control device of the rock wool production line provided by the present invention is as follows: during the operation of the rock wool production line, the raw materials used for rock wool production are poured into the rock wool raw material bucket 1 respectively, and the raw materials fall into the inside of the weighing frame plate 5 after entering the rock wool raw material bucket 1. At this time, the weight of the rock wool raw materials will be transmitted to the surface of the weighing slide plate 3 through the discharge plate 6 and the weighing frame plate 5. The weight of the rock wool raw materials is detected by the weighing sensor 4. When the weight is small, the raw materials are continued to be added. When the weight is large, the motor 2 94 is started by the control module 10, and the output shaft of the motor 2 94 drives the turntable 95 to rotate. The inclined surface of the turntable 95 applies a force to the convex column 96. Through the cooperation of the left and right convex columns 96, the support plate 99 drives the weighing frame plate 5 to move left and right, vibrating the rock wool raw materials inside the weighing frame plate 5, so that the rock wool raw materials are layered, and the smaller raw materials are concentrated at the lower end of the weighing frame plate 5. Then the movement of the weighing frame plate 5 is stopped, and the turntable 95 rotates by an angle The change of , determines the left and right positions of the weighing frame plate 5, makes the discharge hole of the weighing frame plate 5 correspond vertically to the discharge hole of the weighing slide plate 3, starts the motor 1 93, and the output shaft of the motor 1 93 drives the rotating plate 92 to rotate. The rock wool raw material is shifted by the rotation of the rotating plate 92, so that the excess rock wool raw material is removed from the removal chute 91. When there is a lot of excess raw material, the upper removal chute 91 is used to remove the larger raw material. When there is less excess raw material, the lower removal chute 91 is used to remove the smaller raw material. The material removal is more accurate, and the ratio between the rock wool raw materials is more accurate. When the rock wool raw material reaches the specified value, the electric push rod 1 7 is started, and the extension of the electric push rod 1 7 is used to drive the discharge plate 6 to rotate around the rotating shaft 1, so that the raw material falls along the inclined discharge plate 6 to the lower end of the rock wool raw material hopper 1. After unloading is completed, the discharge plate 6 returns to a horizontal state, and the above operation is repeated to complete the ratio of the rock wool raw materials. By controlling the ratio between the rock wool raw materials, the density of the rock wool is changed.
