Description

Technical Field

[0001] This utility model belongs to the technical field of rock wool production equipment, specifically relating to a cotton-clothing machine for rock wool production. Background Technology

[0002] The main raw materials for rock wool production are ores such as basalt and dolomite. After being melted at high temperatures, they are processed into thin, unformed rock wool felts using a cotton collecting machine. These felts are then layered and arranged by a cotton laying machine to achieve a certain thickness and number of layers. Subsequently, they are pressed by pressure rollers and sent to a curing oven for curing treatment. Finally, they are cooled, cut, and packaged to produce the finished product. To ensure the uniformity and stability of the rock wool felt during the cotton laying process, a cotton laying machine is usually needed to lay the rock wool felt layer by layer onto a stacking conveyor, thus providing a good foundation for subsequent pressing and curing.

[0003] Currently, the commonly used pendulum cotton laying machine uses a vertical belt conveyor with its upper end hinged to the frame via a fixed shaft. The transmission mechanism drives the vertical belt conveyor to swing back and forth along the fixed shaft, and the rock wool felt falls along the vertical belt conveyor and follows its swing to complete the cotton laying operation. However, this structure has certain limitations: the movement trajectory at the end of the vertical belt conveyor is arc-shaped. When the bottom pendulum moves to the center position, the distance to the stacking conveyor is the closest, while at both ends the distance is the farthest. This results in uneven thickness of the rock wool felt, and wrinkles are easily generated during repeated stacking, affecting the appearance quality and mechanical properties of the product. Utility Model Content

[0004] To overcome the problems of uneven rock wool felt thickness and wrinkles easily generated during repeated stacking caused by the arc-shaped movement trajectory of the vertical belt conveyor in existing pendulum rock wool laying machines, this utility model provides a rock wool laying machine for production. Through the coordinated use of the pendulum conveyor mechanism and the drive mechanism, combined with the mechanical limiting function of the support frame, the linear reciprocating motion of the end of the pendulum conveyor mechanism is achieved, ensuring that the distance between its end and the conveyor belt of the stacking conveyor remains constant. This results in uniform rock wool felt thickness and improves the product's appearance quality and mechanical properties.

The end of the transmission shaft is mounted on the U-shaped mounting plate via a bearing and is located in the gap below the conveyor belt of the stacking conveyor. One end of the transmission shaft passes through the U-shaped mounting plate and is connected to the output shaft of the second motor.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a cotton-clothing machine for rock wool production, the overall structure of which is as follows: Figure 1As shown, the system mainly includes a frame 1, a stacking conveyor 2, a support frame 3, a pendulum conveying mechanism 4, a drive mechanism 5, and U-shaped mounting plates 6. The frame 1 serves as the main support structure for the entire equipment. U-shaped mounting plates 6 are horizontally mounted on both sides of its top, with their open sides facing each other. The stacking conveyor 2 is horizontally fixed between the U-shaped mounting plates 6 and driven by a power unit to convey rock wool felt. The support frame 3 is a U-shaped frame structure, with its bottom fixedly mounted on the U-shaped mounting plates 6, located in the middle of the frame 1. The top of the pendulum conveying mechanism 4 is slidably mounted on the support frame 3. The drive mechanism 5 is installed between the U-shaped mounting plates 6 and connected to the bottom of the pendulum conveying mechanism 4, used to drive the end of the pendulum conveying mechanism 4 to move linearly back and forth.

[0020] The specific structure of the pendulum conveying mechanism 4 is as follows: Figure 2 , Figure 3 As shown, the system includes a first slider 41, a support block 42, a drive roller 43, a driven roller 44, a conveyor belt 45, a first motor 46, and a connecting plate 47. A groove 31 is vertically formed on the side wall of the support frame 3, within which the first slider 41 is slidably mounted. The end of the drive roller 43 is mounted on the first slider 41 via a bearing. The support block 42 is mounted on the drive mechanism 5, and the end of the driven roller 44 is mounted on the support block 42 via a bearing. The conveyor belt 45 is wound between the drive roller 43 and the driven roller 44. The first motor 46 is mounted on the first slider 41 and electrically connected to the controller; its output shaft is connected to the end of the drive roller 43 via a coupling. One end of the connecting plate 47 is mounted on the end of the drive roller 43 via a bearing, and the other end is mounted on the end of the driven roller 44 via a bearing, thus achieving a rigid connection between the drive roller 43 and the driven roller 44. A first guide roller 48 is installed between the first sliders 41, with its end mounted on the first slider 41 via a bearing, positioned above the conveyor belt 45. A second guide roller 49 is installed between the support blocks 42. The end of the second guide roller 49 is mounted on the support block 42 by a bearing and is also located above the conveyor belt 45.

[0021] The specific structure of the drive mechanism 5 is as follows: Figure 5 , Figure 6As shown, the system includes a lead screw 51, a drive shaft 52, a driving bevel gear 53, a driven bevel gear 54, a second motor 55, and a moving block 56. The second motor 55 is mounted on the side of the U-shaped mounting plate 6 and electrically connected to the controller. The end of the drive shaft 52 is mounted on the U-shaped mounting plate 6 via a bearing and is located in the gap below the conveyor belt of the stacking conveyor 2. One end of the drive shaft 52 passes through the U-shaped mounting plate 6 and is connected to the output shaft of the second motor 55. The end of the lead screw 51 is mounted on a partition inside the U-shaped mounting plate 6 via a bearing. A proximity switch electrically connected to the controller is installed on the side wall of the partition to detect the position signal when the moving block 56 reaches the end of the lead screw 51. When the trigger signal is triggered, the controller controls the second motor 55 to reverse. One end of the lead screw 51 passes through the partition and is mounted with the driven bevel gear 54. The driving bevel gear 53 is mounted on the end of the drive shaft 52 and meshes with the driven bevel gear 54. A movable block 56 is threaded onto the lead screw 51. A vertical support rod 57 is provided on the top of the movable block 56. A guide groove 61 is provided on the side wall of the U-shaped mounting plate 6 along its length. The top of the support rod 57 passes through the guide groove 61 and is fixedly connected to the support block 42.

[0022] like Figure 4 As shown, two guide rails 32 are installed on the side wall of the support frame 3, and a second slider 33 is slidably installed on the guide rails 32. The first motor 46 is installed on the second slider 33 through the support plate.

[0023] like Figure 3 As shown, a first gear 431 is installed at the end of the driving roller 43 and the driven roller 44, and a second gear 481 is installed at the end of the first guide roller 48 and the second guide roller 49. The first gear 431 meshes with the second gear 481. A protective shell is installed on the outside of the first gear 431 and the second gear 481. The protective shell is fixed to the side wall of the U-shaped mounting plate by bolts, covering the gear meshing area, which is convenient for disassembly and maintenance.

[0024] In actual operation, one end of the rock wool felt passes sequentially through the first guide roller 48 and the second guide roller 49 and is then laid on the conveyor belt 45. The first motor 46 is started, driving the drive roller 43 to rotate. The drive roller 43, through the conveyor belt 45, drives the driven roller 44 to rotate, thus conveying the rock wool felt. Simultaneously, the second motor 55 is started, driving the transmission shaft 52 to rotate. The transmission shaft 52 transmits power to the lead screw 51 through the meshing of the drive bevel gear 53 and the driven bevel gear 54. The rotational motion of the lead screw 51 is converted into the linear motion of the moving block 56. The moving block 56, through the support rod 57, drives the support block 42 to reciprocate horizontally, thereby driving the driven roller 44 at the bottom of the pendulum conveyor mechanism 4 to reciprocate horizontally. The driven roller 44, through the connecting plate 47, pushes the drive roller 43 and the first slider 41 to reciprocate up and down along the chute 31. When the driven roller 44 moves to the bottom of the support frame 3, the driving roller 43 moves to the top of the chute 31, completing the distance change compensation during the movement of the pendulum conveying mechanism 4.

[0025] The first guide roller 48 and the second guide roller 49 limit the movement of the rock wool felt during conveying, preventing it from wrinkling or shifting. The meshing structure of the first gear 431 and the second gear 481 ensures synchronous operation between the components, and the installation of the protective shell enhances the safety and reliability of the equipment operation. The guide rail 32 and the second slider 33 on the support frame 3 further improve the installation stability of the first motor 46, ensuring that it will not shift due to vibration during operation.

[0026] In the above embodiments, the end of the pendulum conveying mechanism 4 achieves linear reciprocating motion through the cooperation of the drive mechanism 5, and simultaneously completes vertical compensation motion through the cooperation of the first slider 41 and the slide 31, ensuring that the distance between the end of the pendulum conveying mechanism 4 and the conveyor belt of the stacking conveyor 2 remains constant. This avoids the problem of uneven rock wool felt laying thickness caused by the arc-shaped movement trajectory of the end of the vertical belt conveyor in the prior art. The limiting function of the first guide roller 48 and the second guide roller 49 further enhances the stability during the conveying process, ensuring that the rock wool felt will not wrinkle or shift during laying. To better enable those skilled in the art to fully understand and implement this utility model, the following provides a detailed supplement to the operating principle and implementation steps of the cotton laying machine in conjunction with specific application scenarios.

[0027] In the rock wool production process, the core task of the rock wool laying machine is to evenly lay the rock wool felt layer by layer onto the stacking conveyor. To achieve this goal, it is first necessary to ensure that the end of the pendulum conveyor mechanism 4 can perform linear reciprocating motion in the horizontal direction, while maintaining a constant distance between it and the stacking conveyor 2 through an up-and-down compensation mechanism. The following are the specific steps of the entire rock wool laying process and its principle explanation: Initially, one end of the rock wool felt is introduced into the cotton-laying machine and sequentially passes through the first guide roller 48 and the second guide roller 49 before being laid on the conveyor belt 45. The first guide roller 48 is installed between the first sliders 41, and the second guide roller 49 is installed between the support blocks 42, both located above the conveyor belt 45. This arrangement limits the movement of the rock wool felt during transport, preventing deviation or wrinkling. Second gears 481 are respectively installed at the ends of the first guide roller 48 and the second guide roller 49. The second gears 481 mesh with the first gears 431 at the ends of the driving roller 43 and the driven roller 44, thereby ensuring that the movement of the conveyor belt 45 is synchronized and coordinated with the limiting function of the guide rollers.

[0028] Subsequently, the first motor 46 is started, driving the drive roller 43 to rotate via a coupling. The rotational motion of the drive roller 43 is transmitted to the driven roller 44 via the conveyor belt 45, thereby driving the entire conveyor belt 45 to operate and achieving continuous conveying of the rock wool felt. Simultaneously, the second motor 55 is started, driving the transmission shaft 52 to rotate via forward and reverse rotation. One end of the transmission shaft 52 is equipped with a drive bevel gear 53, which meshes with the driven bevel gear 54, thus transmitting the rotational motion to the lead screw 51. The rotational motion of the lead screw 51 is converted into the linear motion of the moving block 56 via a threaded connection. The support rod 57 at the top of the moving block 56 passes through the guide groove 61 on the U-shaped mounting plate 6 and is fixedly connected to the support block 42. The width of the guide groove 61 is the diameter of the support rod 57 + 0.5mm tolerance. Therefore, the linear motion of the moving block 56 directly drives the support block 42 to reciprocate horizontally along the guide groove 61.

[0029] The horizontal movement of the support block 42 further propels the end of the pendulum conveying mechanism 4 to perform a horizontal reciprocating motion. Since the driving roller 43 is rigidly connected to the driven roller 44 via the connecting plate 47, the horizontal movement of the driven roller 44 simultaneously drives the driving roller 43 and the first slider 41 to move up and down along the chute 31. The length of the chute 31 is greater than 0.5 times the horizontal stroke of the driven roller 44. When the driven roller 44 moves to the bottom of the support frame 3 (horizontal stroke L), the driving roller 43 just moves to the top of the chute 31 (vertical displacement 0.5L), completing the compensation for distance changes during the movement of the pendulum conveying mechanism 4. This vertical compensation mechanism ensures that the distance between the end of the pendulum conveying mechanism 4 and the conveyor belt of the stacking conveyor 2 remains constant, thus solving the problem of uneven rock wool felt thickness caused by the arc-shaped movement trajectory of the end of the vertical belt conveyor in the prior art.

[0030] During the conveying process of rock wool felt, the first guide roller 48 and the second guide roller 49 play particularly important roles. The first guide roller 48 moves up and down along the slide groove 31 with the first slider 41, while the second guide roller 49 moves back and forth horizontally with the support block 42. The synergistic effect of the two not only limits the rock wool felt but also effectively prevents it from wrinkling or shifting during conveying. In addition, the meshing structure of the first gear 431 and the second gear 481 makes the conveying process of rock wool felt smoother, and the installation of the protective shell enhances the safety of equipment operation.

[0031] The guide rail 32 and the second slider 33 mounted on the side wall of the support frame 3 further enhance the installation stability of the first motor 46. The first motor 46 is mounted on the second slider 33 via a support plate, and the second slider 33 slides along the guide rail 32, thereby ensuring that the first motor 46 will not be displaced due to vibration during operation. This not only improves the overall stability of the equipment but also extends the service life of key components.

[0032] Through the above steps, the rock wool felt laying machine achieves uniform laying. The linear reciprocating motion at the bottom of the pendulum conveying mechanism 4, combined with the up-and-down compensation mechanism of the first slider 41, solves the problem of uneven laying thickness caused by motion trajectory issues in existing technologies. At the same time, the limiting effect of the first guide roller 48 and the second guide roller 49 improves the stability of the rock wool felt during the conveying process, ensuring that the rock wool felt will not wrinkle or shift during laying. This structure not only improves the appearance quality of the product but also optimizes the mechanical properties of the rock wool felt, laying a good foundation for subsequent pressing and curing processes.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
