Description

Technical Field

[0001] This utility model relates to the field of rock wool production technology, specifically to a rock wool density adjustment device for rock wool production. Background Technology

[0002] Rock wool products are made from high-quality basalt, dolomite and other raw materials. After being melted at a high temperature of over 1450℃, they are centrifuged into fibers using an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dustproof oil and water-repellent agent are sprayed in. The fibers are then collected by a cotton collecting machine, and after being laid in a three-dimensional manner using a pendulum method, they are cured and cut to form rock wool products of different specifications and uses.

[0003] Application No. CN202420569621.0 discloses a density control device for rock wool production, including a support frame with four welded feet at the bottom corners and a connecting frame fixedly connected to the top of the support frame. This density control device for rock wool production incorporates a cutting scraper, a toothed groove, and a gear. A throttle handle causes the outer teeth of the gear to disengage from the toothed groove, thus freeing the rotating shaft. Rotating the shaft causes the cutting scraper to rotate, allowing adjustment of the scraper's bottom height. Adjusting the scraper's height controls the rock wool thickness, removing excess rock wool and thus controlling the density of the produced rock wool. After adjustment, pulling the throttle handle causes the outer teeth of the gear to engage with the toothed groove, securing the rotating shaft and the cutting scraper. This device addresses the problem of inconvenient and inaccurate control of the density of produced rock wool, which can easily affect its quality.

[0004] While the aforementioned document allows for precise control of the bulk density in rock wool production, the adjusted cutting blade remains stationary. When scraping away excess rock wool, the excess rock wool is pulled up along with the rock wool below the cutting blade, easily bringing out more rock wool and causing a decrease in the bulk density of the rock wool. Consequently, it becomes impossible to precisely control the bulk density of the rock wool. To address these issues, the inventor proposes a rock wool bulk density adjustment device for rock wool production. Utility Model Content

[0005] To address the issue that the adjusted cutting scraper remains stationary, which can easily bring out more rock wool during scraping of excess rock wool, leading to a decrease in the density of the rock wool, the purpose of this invention is to provide a rock wool density adjustment device for rock wool production.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a rock wool density adjustment device for rock wool production, including a base plate, an ear plate fixedly provided on the top surface of the base plate, a rotating shaft rotatably provided between the ear plates, the number of the rotating shafts being two, a conveyor belt being connected between the two rotating shafts, a first motor being installed on one side of the ear plate, and one end of one of the rotating shafts being fixedly connected to the output end of the first motor;

[0007] A fixed frame is fixedly provided on the top surface of the base plate, a support frame is slidably provided inside the fixed frame, a support plate is provided below the support frame, a cutter is fixedly provided between the support plates, a positioning frame is fixedly provided on the top surface of the support plate, an mounting plate is fixedly provided between the positioning frames, a second motor is fixedly provided on the bottom surface of the support frame, a half-face gear is fixedly provided at the output end of the second motor, a toothed plate is fixedly provided inside the mounting plate, the toothed plate meshes with the half-face gear, there are two sets of toothed plates, and the two sets of toothed plates are arranged opposite to each other, a movable plate is slidably provided inside the support plate, the movable plate is slidably provided inside the fixed frame, a sliding groove is provided inside the support plate, a sliding rod is fixedly provided inside the sliding groove, and the movable plate is slidably sleeved on the outer surface of the sliding rod. First, by turning on the first motor, the connected rotating shaft is rotated, and in conjunction with another rotating shaft, the conveyor belt drives the material transmission. Then, the rock wool in the processing process is conveyed onto the conveyor belt. By turning on the first cylinder, the support frame drives the movable plate to slide inside the fixed frame, thereby allowing the height of the cutter to be adjusted.

[0008] Next, the second motor is turned on, which causes the half-face gear to rotate, and then the half-face gear can mesh with one of the tooth plates, which can drive the mounting plate to move. Then, when the half-face gear disengages from the tooth plate, it can mesh with the other tooth plate, causing the mounting plate to move in the opposite direction. At the same time, the support plate slides on the outer surface of the moving plate, and the cutter can reciprocate. Therefore, when scraping off excess rock wool, no more rock wool will be carried out, avoiding a decrease in the density of the rock wool, and thus the density of the rock wool can be precisely controlled.

[0009] By activating the second cylinder, the connecting plate moves the fixed ear, causing the pressure roller to adhere to the rock wool on the conveyor belt. This allows the pressure roller to rotate on the outer surface of the rotating rod, simultaneously pressing the rock wool and compacting it.

[0010] Preferably, a first cylinder is installed on the top surface of the fixed frame, the output end of the first cylinder is fixedly disposed on the top surface of the support frame, a groove is provided in the fixed frame, a movable rod is fixedly disposed in the groove, and the movable plate is slidably sleeved on the outer surface of the movable rod.

[0011] Preferably, a U-shaped frame is fixedly provided on the top surface of the base plate, a connecting plate is slidably provided inside the U-shaped frame, a fixing ear is fixedly provided on the bottom surface of the connecting plate, a rotating rod is rotatably provided between the fixing ears, a pressure roller is fixedly sleeved on the outer surface of the rotating rod, a second cylinder is installed on the top surface of the U-shaped frame, and the output end of the second cylinder is fixedly provided on the top surface of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The support plate slides on the outer surface of the moving plate, and the cutter can move back and forth. When scraping off excess rock wool, the excess rock wool will not be pulled up along with the rock wool below the cutter, and more rock wool will not be brought out, thus avoiding a decrease in the density of the rock wool and enabling precise control of the density of the rock wool.

[0014] 2. By opening the second cylinder, the connecting plate moves the fixed ear, causing the pressure roller to adhere to the rock wool on the conveyor belt. This allows the pressure roller to rotate on the outer surface of the rotating rod, simultaneously pressing the rock wool and compacting it. Attached Figure Description

[0024] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-7 As shown, this utility model provides a rock wool density adjustment device for rock wool production, including a base plate 1, an ear plate 11 fixedly provided on the top surface of the base plate 1, and two rotating shafts 13 rotatably provided between the ear plates 11. A conveyor belt 14 is connected between the two rotating shafts 13. A first motor 12 is installed on one side of the ear plate 11. One end of one of the rotating shafts 13 is fixedly connected to the output end of the first motor 12. By turning on the first motor 12, the connected rotating shaft 13 is rotated, and the other rotating shaft 13 drives the conveyor belt 14 to drive the material transmission. Thus, the rock wool in the processing process is conveyed to the conveyor belt 14 and transported.

[0026] A fixed frame 2 is fixedly mounted on the top surface of the base plate 1. A support frame 22 is slidably mounted inside the fixed frame 2. A support plate 25 is mounted below the support frame 22. A cutter 27 is fixedly mounted between the support plates 25. A positioning frame 3 is fixedly mounted on the top surface of the support plate 25. An mounting plate 31 is fixedly mounted between the positioning frames 3. A second motor 32 is fixedly mounted on the bottom surface of the support frame 22. A half-face gear 33 is fixedly mounted at the output end of the second motor 32. A toothed plate 34 is fixedly mounted inside the mounting plate 31. The toothed plate 34 meshes with the half-face gear 33. There are two sets of toothed plates 34, and the two sets of toothed plates 34 are arranged opposite to each other. A movable plate 23 is slidably mounted inside the support plate 25. The movable plate 23 is slidably mounted inside the fixed frame 2. A sliding groove 251 is opened inside the support plate 25. An internally fixed sliding rod 26 is provided, and a movable plate 23 is slidably sleeved on the outer surface of the sliding rod 26. By turning on the second motor 32, the half-face gear 33 is rotated, which allows the half-face gear 33 to mesh with one of the toothed plates 34, thus driving the mounting plate 31 to move. Then, when the half-face gear 33 disengages from the teeth of the toothed plate 34, it can mesh with the other toothed plate 34, causing the mounting plate 31 to move in the opposite direction. At the same time, the support plate 25 is slidably sleeved on the outer surface of the movable plate 23, and the cutter 27 can reciprocate. Thus, when scraping off excess rock wool, the excess rock wool will not be pulled up along with the rock wool below the cutter 27, and more rock wool will not be brought out, avoiding a decrease in the density of the rock wool. This allows for precise control of the density of the rock wool.

[0027] A first cylinder 21 is installed on the top surface of the fixed frame 2. The output end of the first cylinder 21 is fixedly located on the top surface of the support frame 22. A groove 201 is provided inside the fixed frame 2. A movable rod 24 is fixedly installed inside the groove 201. A movable plate 23 is slidably sleeved on the outer surface of the movable rod 24.

[0028] By adopting the above technical solution, by opening the first cylinder 21, the support frame 22 drives the moving plate 23 to slide within the fixed frame 2, thereby allowing the height of the cutter 27 to be adjusted, and thus the thickness of the rock wool to be controlled.

[0029] A U-shaped frame 4 is fixedly provided on the top surface of the base plate 1. A connecting plate 42 is slidably provided inside the U-shaped frame 4. A fixing ear 43 is fixedly provided on the bottom surface of the connecting plate 42. A rotating rod 44 is rotatably provided between the fixing ears 43. A pressure roller 45 is fixedly sleeved on the outer surface of the rotating rod 44. A second cylinder 41 is installed on the top surface of the U-shaped frame 4. The output end of the second cylinder 41 is fixedly provided on the top surface of the connecting plate 42.

[0030] By adopting the above technical solution, by opening the second cylinder 41, the connecting plate 42 drives the fixed ear 43 to move, causing the pressure roller 45 to adhere to the rock wool on the conveyor belt 14, thereby enabling the pressure roller 45 to rotate on the outer surface of the rotating rod 44, and simultaneously pressing the rock wool, thus compacting the rock wool.

[0031] Working principle: First, by turning on the first motor 12, the connected rotating shaft 13 is rotated, and in conjunction with another rotating shaft 13, the conveyor belt 14 drives the material transmission. Then, the rock wool in the processing process is conveyed onto the conveyor belt 14. By turning on the first cylinder 21, the support frame 22 drives the moving plate 23 to slide within the fixed frame 2, thereby allowing the height of the cutter 27 to be adjusted.

[0032] Next, the second motor 32 is turned on, which causes the half-face gear 33 to rotate, thereby enabling the half-face gear 33 to mesh with one of the toothed plates 34, so that it can drive the mounting plate 31 to move. Then, when the half-face gear 33 separates from the teeth of the toothed plate 34, it can mesh with the other toothed plate 34, causing the mounting plate 31 to move in the opposite direction. At the same time, the support plate 25 slides on the outer surface of the moving plate 23, and the cutter 27 can reciprocate. Thus, when scraping off excess rock wool, the excess rock wool will not be pulled up along with the rock wool below the cutter 27, and more rock wool will not be brought out, thus avoiding a decrease in the density of the rock wool. This allows for precise control of the density of the rock wool.

[0033] By activating the second cylinder 41, the connecting plate 42 moves the fixed ear 43, causing the pressure roller 45 to adhere to the rock wool on the conveyor belt 14, thereby enabling the pressure roller 45 to rotate on the outer surface of the rotating rod 44 and simultaneously press the rock wool, thus compacting the rock wool.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
