Description

Technical Field

[0001] This invention belongs to the field of rock wool cutting technology and relates to a protective rock wool cutting device for pipelines. Background Technology

[0002] Rock wool composite insulation panels are made by using colored steel or aluminum plates as the surface layer on top of rock wool boards. This reduces the construction period by 70% during installation and use, effectively improving project progress. The main material of the rock wool composite panel is basalt rock wool board, made from basalt, iron ore, bauxite, and other raw materials. These artificial inorganic fibers are produced through high-temperature melting and processing with the addition of appropriate binders. They are lightweight, have low thermal conductivity, absorb heat, and are non-combustible. The thickness of the rock wool varies from 10 mm to 200 mm. 10 mm thick rock wool boards are used for pipe insulation and fireproofing. When installing protective rock wool on pipes, a roll of rock wool needs to be cut into small pieces for wrapping.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] like Figure 1-8 As shown, this invention is a pipe protective rock wool cutting device, including a base plate 1 and a pressing assembly. A placement frame 3 is provided on the base plate 1, and the bottom of the inner cavity of the placement frame 3 has an arc-shaped transition. A vertical plate 31 is provided on the top of the placement frame 3, and a driving assembly is installed on one side of the vertical plate 31. A push plate 6 is provided on one side of the vertical plate 31 and on the driving assembly. A U-shaped frame 61 is provided at one end of the push plate 6, and one end of the U-shaped frame 61 has an arc-shaped structure. A second pressing rod 62 is rotatably provided inside the U-shaped frame 61. A rotating rod 63 is also provided inside the U-shaped frame 61, and the rotating rod 63 has an opening for the second pressing rod 62. 2. A sliding groove 64 is provided. A pressure ring 65 that works with the second pressure rod 62 is slidably sleeved on the outside of the rotating rod 63. The pressure ring 65 is slidably connected to the outside of the rotating rod 63. A retaining ring 66 is provided at one end of the rotating rod 63. A second spring 67 is provided between the retaining ring 66 and the pressure ring 65. The second spring 67 is sleeved on the outside of the rotating rod 63. A pressure block 68 is provided at the lower end of the retaining ring 66. The lower end of the pressure block 68 is arc-shaped. A sliding rod 45 is provided through the inside of the pressure block 68. The two ends of the sliding rod 45 are slidably connected to the pressing assembly. A pair of cutters 46 are provided on the outside of the sliding rod 45.

[0026] Preferably, the cutter 46 is provided with two nuts 47 on its outer side. The nuts 47 are screwed to the slide rod 45, and the two nuts 47 are rotated at the same time to fix one of the cutters 46. By rotating the nuts 47, the position of the cutter 46 can be changed to adapt to different needs. When it is necessary to fix one of the cutters 46, simply place the cutter 46 in the desired position and rotate the corresponding nut 47. The rotation of the nut 47 will cause it to be tightly engaged with the thread on the slide rod 45, thereby fixing the cutter 46 in the desired position, so that the cutter 46 can be easily fixed in any desired position.

[0027] Preferably, the pressing assembly includes a first pressing plate 4, a first pressing rod 41, a first spring 42, a second pressing plate 43, and a sliding groove 44. A pair of second pressing plates 43 are slidably disposed on the placement frame 3. The lower end of the second pressing plate 43 is at a distance from the bottom of the placement frame 3. A sliding groove 44 is provided on the opposite side of the two second pressing plates 43. The two ends of the sliding rod 45 are respectively located in the sliding groove 44. The upper end of the second pressing plate 43 is connected to the first pressing plate 4 through the first pressing rod 41. The first pressing plate 4 contacts the lower end of the U-shaped frame 61. The first pressing plate 4 and the placement frame 3 are connected by two first springs 42. When cutting the protective rock wool, the C-shaped frame 61 rotates around the drive shaft 51, and the drive shaft 51 forms a semi-circular ring during the rotation. When the C-shaped frame 61 rotates around the drive shaft 51 to the lowest point, the C-shaped frame 61 will squeeze the first pressure plate 4. When the first pressure plate 4 is squeezed, the force is transmitted to the second pressure plate 43 through the first pressure rod 41, and the first spring 42 is compressed at the same time. The second pressure plate 43 moves downward due to the squeezing of the first pressure rod 41, thus completing the squeezing operation of the protective rock wool. During the extrusion process, the cutter 46 is positioned above the first pressure plate 4 and is fixed by the adjusting nut 47; when the second pressure plate 43 moves downward, the cutter 46 cuts the protective rock wool; due to the appropriate extrusion force on the first pressure plate 4 and the second pressure plate 43, the cutter 46 can stably cut the protective rock wool, ensuring cutting quality and efficiency; the extrusion and cutting of the protective rock wool are realized by the rotation of the C-shaped frame 61 around the drive shaft 51; at the same time, the design of the first pressure rod 41 and the spring 42 ensures the uniform distribution of extrusion force and just the right elastic rebound; To ensure the effectiveness and flexibility of the pressing action, the first pressure plate 4 is connected to the placement frame 3 by two first springs 42; in this way, when the pressing force is released, the springs 42 can return the first pressure plate 4 to its original position, ensuring the stability and reliability of the placement frame.

[0028] In this embodiment, the driving assembly includes a motor 5, a drive shaft 51, a rotating plate 52, and push rods 54. The motor 5 is mounted on a vertical plate 31. The output end of the motor 5 is provided with a drive shaft 51 extending out of the vertical plate 31. A rotating plate 52 is provided at one end of the drive shaft 51 near the motor 5. Push rods 54 are rotatably connected to the outer sides of both ends of the rotating plate 52. The other end of the drive shaft 51 is connected to the push plate 6. The rotating plate 52 has a V-shaped structure. One end of the rotating plate 52 is provided with a half gear 53, and a gear 27 meshes on the half gear 53. The gear 27 is sleeved on the support component through a limiting component. In the above text, the drive assembly is the key part for cutting protective rock wool. The start of motor 5 controls the forward and reverse rotation of drive shaft 51. With the forward and reverse rotation of drive shaft 51, rotating plate 52 connected to drive shaft 51 reciprocates. When not in operation, pressure block 68 abuts against the corner of the inner cavity of placement frame 3, while one of the push rods 54 contacts push plate 6. At this time, the angle between push plate 6 and rotating rod 63 is approximately ninety degrees. With the start of motor 5, rotating plate 52 drives push rod 54 to reciprocate. When motor 5 rotates forward, push rod 54 pushes push plate 6 to rotate counterclockwise. Simultaneously with the counterclockwise rotation of push plate 6, second pressure rod 62 compresses pressure ring 65 and second spring 67. When push plate 6 rotates counterclockwise to vertically downward, second pressure rod 62 compresses pressure ring 65 and second spring 67 to their maximum compression value. When push plate 6 continues to rotate counterclockwise, when it reaches the point where rotating rod 63 contacts push plate 6... 6. Maintaining a straight line, the second spring 67 is about to return to its original position. When the push plate 6 continues to rotate counterclockwise, the friction between the pressure block 68 and the placement frame 3 will be less than the elastic force of the second spring 67. The second spring 67 returns to its original position, causing the rotating rod 63 to rotate counterclockwise, so that the pressure block 68 slides across the protective rock wool. While the pressure block 68 slides across the protective rock wool, the slide rod 45 slides on the slide groove 44, simultaneously driving the cutter 46 to slide across the protective rock wool, thus cutting the protective rock wool. Similarly, the reverse rotation of the motor 5 will drive the cutter 46 to cut in the opposite direction, again cutting the protective rock wool. Through the above description, it can be seen that the entire cutting process is realized under the action of the drive assembly. The coordinated movement of components such as the push plate 54, the second pressure rod 62, the pressure ring 65, the second spring 67, the rotating rod 63, the pressure block 68, the slide rod 45, and the cutter 46 ensures accurate cutting of the protective rock wool. This design can improve cutting speed and precision, enabling efficient processing of protective rock wool; In this embodiment, the limiting component includes a drive ring 271, an elastic telescopic rod 272, a connecting plate 273, and a baffle 274. The gear 27 has a drive ring 271 inside, and at least two limiting grooves are opened on the outer ring surface of the drive ring 271. The inner ring surface of the gear 27 has an elastic telescopic rod 272 that cooperates with the limiting grooves. The elastic telescopic rod 272 has a connecting plate 273, and the connecting plate 273 has a baffle 274 that contacts the groove wall of the limiting groove. During the rotation of the rotating plate 52, the half gear 53 is driven to rotate. Since the half gear 53 meshes with the gear 27, it drives the gear 27 to rotate. The gear 27 has a limiting component inside, and through the connection of the limiting component, it drives the first rotating rod 31 to rotate. The elastic telescopic rod 272 is initially located in the limiting groove, and one side of the limiting groove is in contact with the baffle 274. The other side of the limiting groove adopts an arc transition and is used to cooperate with the arc surface of one end of the connecting plate 273. When the rotating plate 52 flips, the arc surface of the limiting groove presses the elastic telescopic rod 272, so that the elastic telescopic rod 272 drives the connecting plate 273 and the baffle 274 to move, so that the drive ring 271 can rotate automatically.

[0029] In this embodiment, the base plate 1 is provided with three first support rods 2 and one second support rod 22. The upper end of each of the first support rods 2 is provided with a ring 24. Two of the rings 24 are rotatably connected to a first rotating rod 21. The drive ring 271 is sleeved on the first rotating rod 21. The other ring 24 is rotatably connected to a second rotating rod 23. One end of the second rotating rod 23 and one end of the first rotating rod 21 are connected by a driving bevel gear 25 and a driven bevel gear 26. The upper end of the second support rod 22 is provided with a semi-circular ring, and the open end of the semi-circle is made of elastic material. Under the action of pressing, the second rotating rod 23 is inserted into the interior of the semi-circular ring. The second rotating rod 23 is provided in two sections, one of which is located inside the circular ring 24 and the other is located inside the semi-circular ring. The two sections of the second rotating rod 23 are hinged to allow one of the second rotating rods 23 to be folded upwards by ninety degrees. In use, the second rotating rod 23 is folded over, and the rolled-up protective rock wool is inserted into the second rotating rod 23. Then, the second rotating rod 23 is folded down, and one end of the second rotating rod 23 is inserted into the interior of the semi-circular ring to fix the protective rock wool. While the drive ring 271 is rotating, the first rotating rod 21 also rotates. Since the first rotating rod 21 and the second rotating rod 23 are connected by the driving bevel gear 25 and the driven bevel gear 26, the second rotating rod 23 is driven to rotate, which in turn drives the protective rock wool to rotate, thus completing the cutting of the protective rock wool.

[0030] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
