[0002] Rock wool is made by melting basalt, dolomite, coke, etc. into magma in a furnace at about 1400 °C. The magma will fall on a high-speed roller through a material guiding groove, and various specifications of rock wool products are made through procedures such as collection by a collector, stacking by a pendulum, curing, cutting, and packaging. In recent years, due to the diversified trend of the uses of rock wool boards, the requirements for product quality are getting higher and higher.

[0031] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0032] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Figure 1 It is the structure schematic diagram of the packaging system of the rock wool production line, including the conveying rack 11. A conveying mechanism is arranged on the conveying rack 11. The rock wool board moves along the conveying rack under the drive of the conveying mechanism. The conveying mechanism adopts a structure commonly used in the rock wool production field and can be a conveying belt or a conveying roller.

[0034] At this time, the incoming material is the cut rock fiber board. The figure shows a 2.4-meter production line. There are 4 conventional boards in each row. In the figure, 1 is the rock fiber board. After passing through the transition belt 9 on the conveying rack 11, it is transported to the inspection roller path 10. An infrared detection device 2 and a vision detection device 3 are set at the inspection roller path 10. In the figure, 2 is the infrared detection device, with four arranged on the upper and lower parts of the conveying rack respectively. 3 is the vision detection device, also with four equipped on the upper and lower parts respectively, corresponding to the four boards in sequence. The conveying method at the position of the detection device is roller path conveying, and there are gaps between the roller paths, so as to enable the vision detection below to be normally detected through the roller path gaps. The infrared detection device is specifically an infrared temperature detector, which detects internal burned cotton or flowing slag based on temperature changes. The vision detection device is specifically a vision detection machine, which includes detecting aspects such as the size and appearance of the board and conducts double-sided detection.

[0035] Behind the inspection roller path 10 is the material distribution lifting belt 4. Lifting belt devices with the same number as the rock fiber boards are set. The material distribution lifting belt 4 is connected to the conveying belt at the back, and conveys the qualified rock fiber boards to the next process.

[0036] The material distribution lifting belt 4 includes several groups of lifting belts. Each lifting belt respectively includes a belt and a bracket. Rollers are set at both ends of the bracket, and the belt bypasses the rollers and moves under the drive of the motor. As Figure 3 shown, each bracket is connected to the conveying rack 11 through a crank rocker mechanism 12, so as to realize the swing of each lifting belt centered on the front roller of itself. The crank rocker mechanism 12 includes a lifting drive motor 1205 fixedly set on the conveying rack 11, a cam 1204 connected to the lifting drive motor 1205, and a connecting rod 1202. Both ends of the connecting rod 1202 are respectively connected to the bracket of the material distribution lifting belt 4 and the cam 1204 through a first rotating shaft 1201 and a second rotating shaft 1203. The lifting drive motor 1205 drives the cam to make a rotary motion, pulling the connecting rod 1202 to drive the corresponding group of lifting belts to realize lifting.

[0037] Behind the material distribution lifting belt, a crusher 5 and a belt conveyor 6 are set under the conveying rack 11. The belt conveyor 6 is located below the discharge port of the crusher 5 to realize long-distance conveying. The long direction of the belt conveyor 6 is perpendicular to the conveying rack. The belt conveyor 6 is connected to a bag type dust collector 7, and the bag type dust collector 7 is connected to a recovery box 8.

[0038] The whole process is controlled by DCS. The detection device will transmit the real-time detection signal (qualified or unqualified) to the PLC in the form of switch input. At this time, the PLC program controls the movement of the material distribution lifting belt 4. The material distribution lifting belt 4 is divided into 4 parts, and each part corresponds to a sheet of board, which can move independently. As shown in the figure, if the rightmost board is detected as unqualified, the rightmost belt will move and the tail end will descend, throwing the unqualified board into the crusher 5, and the rest will move along the normal conveying route. The material distribution lifting movement is controlled by the crank rocker mechanism at the lower part of the frame through the forward and reverse rotation of the motor. After the waste board enters the crusher, it is crushed, and the crushed powder is pushed onto the rear belt conveyor 6. There is a dust collection device at the tail end of the belt conveyor 6, which sucks the powder into the bag filter 7. The bag filter collects the powder and discharges it into the recycling bin 8 through the discharger, and it can be directly added to the production raw materials for recycling. The use of the bag filter can purify the on-site environment.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
