[0002] In the field of building insulation, irregularly shaped rock wool strips, as a high-performance insulation material, are widely used in various building projects.

[0003] However, traditional irregular rock wool strip preparation devices have many drawbacks in actual production: traditional devices often use a stop-and-cut method, which requires stopping the belt conveyor for each cut and restarting it after the cut is completed. This method greatly reduces production efficiency and increases production costs. Traditional devices often need to be equipped with a large number of sensors and drive equipment to drive the cutting blade to move horizontally or vertically, which not only increases equipment costs but also increases the difficulty of equipment maintenance.

[0014] Example 1; as Figures 1-7 As shown, the device for preparing irregularly shaped rock wool strips proposed in this embodiment includes a frame 2, an outer cover 3, a belt 41, a cutting device, a lifting drive device, and multiple support plates 6. Mounting side plates 1 are provided at both ends of the top of the frame 2; the belt 41 is installed between the two mounting side plates 1, and a first drive assembly for driving the belt 41 is installed on the mounting side plate 1. The first drive assembly includes a first servo motor 43 and two rollers 42. The two rollers 42 are rotatably installed between the two mounting side plates 1, and the belt 41 is sleeved between the two rollers 42. The first servo motor 43 is installed on the mounting side plate 1 and its output shaft is connected to the rotating shaft of the roller 42.

[0015] Multiple support plates 6 are equidistantly arranged around the outer periphery of the belt 41. Each end of a support plate 6 is connected to a first fixing block 181 between itself and the belt 41. Furthermore, a second fixing block 182 is provided at each of the four corners of the multiple support plates 6. The second fixing blocks 182 are not connected to the belt 41. When the support plate 6 rotates to the upper position of the belt 41, the multiple second fixing blocks 182 provide support for the support plate 6. Limiting components are installed on each of the multiple support plates 6. These limiting components include a bidirectional lead screw 17, a knob 19, two first limiting blocks 221, and two second limiting blocks 221.

The end of the bidirectional lead screw 17 is provided with a first gear 20. A rack 23 is provided below the belt 41. A connecting bracket 24 is connected between the rack 23 and the mounting side plate 1.

[0016] The outer cover 3 is located between the two mounting side plates 1. The bottom and left and right ends of the outer cover 3 are open. Dustproof curtains 5 are installed at the openings at both ends of the outer cover 3.

[0017] The cutting device is located inside the outer cover 3. The cutting device includes a second U-shaped frame 10, a high-strength saw wire 11, and a third drive assembly. The lower end of the first U-shaped frame 9 is connected to a mounting plate 12. The second U-shaped frame 10 is slidably mounted on the mounting plate 12. The high-strength saw wire 11 is mounted on the second U-shaped frame 10. The third drive assembly includes a second servo motor 13 and a turntable 15. The second servo motor 13 is mounted on the mounting plate 12. The turntable 15 is connected to the output shaft of the second servo motor 13. A fixed shaft 16 is connected to the edge of the turntable 15. A movable hole 1001 is opened on the second U-shaped frame 10. The fixed shaft 16 is located inside the movable hole 1001. The second servo motor 13 is started to drive the turntable 15 to rotate, which in turn drives the fixed shaft 16 to rotate along the center of the turntable 15. During this process, the fixed shaft 16 moves inside the movable hole 1001, thereby realizing the reciprocating drive of the second U-shaped frame 10.

[0018] The lifting drive device includes a first U-shaped frame 9, two rotating columns 8, two ball bearings 14, and a second drive assembly. The first U-shaped frame 9 movably passes through the upper end of the outer cover 3. The cutting device is installed at the bottom end of the first U-shaped frame 9. The two rotating columns 8 are rotatably mounted on the outer cover 3. The outer periphery of the rotating columns 8 is provided with a movable groove 81. The two ball bearings 14 are both mounted on the first U-shaped frame 9, and the two ball bearings 14 are respectively movably disposed in the movable grooves 81 on both sides. The second drive assembly is installed on the outer cover 3 to drive the two rotating columns 8 to rotate synchronously. The second drive assembly includes a third servo motor 25, a second gear 26, and two third gears 27. The outer cover 3 is provided with a mounting bracket 7. The third servo motor 25 is mounted on the mounting bracket 7. The second gear 26 is mounted on the output shaft of the third servo motor 25. The two third gears 27 are respectively mounted on the rotating shafts of the rotating columns 8 on both sides, and the two third gears 27 mesh with the second gear 26.

[0019] The working principle of this technical solution is as follows: When cutting the rock wool strip, the rock wool strip is quickly placed on the support plate 6, and the rock wool strip is positioned between the two first limiting blocks 221 and the two second limiting blocks 222. Then, the knob 19 is turned to drive the bidirectional screw 17 to rotate. By adjusting the rotation direction of the bidirectional screw 17, the two first limiting blocks 221 can be driven to move closer or further apart, thereby achieving the clamping of the bottom end of the rock wool strip. The two second limiting blocks 222 are mainly used to limit the other two ends of the rock wool strip.

[0020] The first drive assembly drives the belt 41 to move slowly, moving the support plate 6 carrying the rock wool strips into the interior of the outer cover 3. The dust curtains 5 set on both sides of the outer cover 3 can play a certain dust prevention role. The clamped rock wool strips have a certain stability, preventing them from being scraped off the support plate 6 after contacting the dust curtains 5.

[0021] During the slow movement of the rock wool strip, the second U-shaped frame 10 and the high-strength saw wire 11 are driven to reciprocate by the third drive component. When the high-strength saw wire 11 contacts the rock wool strip, the rock wool strip can be cut. During this process, the rotating columns 8 on both sides are driven to rotate synchronously and in the same direction by the second drive component. During the rotation of the rotating columns 8, the ball bearings 14 roll inside the movable groove 81. Since the movable groove 81 is uneven, it guides the ball bearings 14 to move up and down. The ball bearings 14 then drive the first U-shaped frame 9 and the high-strength saw wire 11 to move, thereby realizing the cutting of the rock wool strip. In addition, the designer can design the trajectory of the movable groove 81 according to the cutting shape of the rock wool strip.

[0022] After the rock wool strip is cut, it continues to move towards the end. During this process, the high-strength saw wire 11 in the interval area between two rock wool strips continues to move up and down. When the high-strength saw wire 11 just contacts the next rock wool strip, the ball bearing 14 moves to the initial position inside the movable groove 81. It should be noted that when the high-strength saw wire 11 just contacts each rock wool strip, the ball bearing 14 is located in the same position inside the movable groove 81 to ensure that the top shape of each cut rock wool strip is the same.

[0023] It should be added that the belt 41 needs to be positioned in this technical solution. Specifically, a Hall sensor and a permanent magnet can be installed on the mounting side plate 1 and the belt 41 respectively. When the permanent magnet on the belt 41 approaches the Hall sensor, the Hall sensor feeds back the signal to the control panel 28. It should also be added that the control panel 28 can be installed on the frame 2. The control panel 28 adopts a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly operating interface. Various commands can be easily issued by touching the screen. The control panel 28 controls the belt 41 to stop running. At this time, the belt 41 returns to its initial position.

[0024] When the cut rock wool strip moves to the end of the conveyor belt 41, the waste material at the upper end is automatically separated from the finished product under the action of gravity. When the first gear 20 contacts the rack 23, the first gear 20 rotates, and the bidirectional lead screw 17 rotates to drive the two first limit blocks 221 to separate, thereby releasing the fixing work on the finished rock wool strip. At this time, the finished product falls automatically under the action of gravity. Through the above structure, the automatic separation of finished product and waste material and the automatic screening work are realized.

[0025] Example 2; as Figure 1 and Figure 7 As shown, in this embodiment, a device for preparing irregularly shaped rock wool strips is proposed. Compared with the first embodiment, in this embodiment, one end of the support plate 6 is connected to a connecting shaft 21, and a groove 101 for sliding the end of the connecting shaft 21 is provided on the mounting side plate 1 adjacent to the connecting shaft 21.

[0026] In this embodiment, the end of the connecting shaft 21 moves inside the slide groove 101, thereby supporting the support plate 6, reducing the load on the belt 41 during movement, and preventing bending or sagging of the belt 41, thus providing good guidance for the movement of the support plate 6.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
