Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of autoclaved aerated concrete block production equipment, specifically a top skin removal device for a semi-finished product turning machine. Background Technology
[0002] Currently, in the autoclaved aerated concrete (AAC) block production industry, after the semi-finished product turning machine turns the billet over, the scraper frame driven by the top hydraulic cylinder descends and then rises back to its original position to remove the top skin. Because there is an overlapping area between the working path of the scraper frame and the turning path of the turning machine, if the scraper frame and the turning machine work at the same time, the overlapping areas will collide and affect each other. Therefore, the scraper frame needs to avoid the turning radius of the turning machine, resulting in a very high distance when it is arranged and a long hydraulic cylinder stroke, which affects the operating rhythm of the whole machine. Summary of the Invention
[0003] In order to solve the problems mentioned in the background art, this utility model proposes a top skin removal device for a semi-finished product turning machine.
[0004] A top skin removal device for a semi-finished product turning machine includes two columns, and its installation method, which is independent of the turning machine body, completely eliminates spatial interference constraints.
[0005] Furthermore, the column is fixed to the concrete foundation with anchor bolts to form a stable vertical guide reference, allowing the scraping system to be arranged close to the blank, directly shortening the movement stroke, while isolating the impact of the turning machine vibration on the scraping accuracy.
[0006] Furthermore, the column surface is equipped with a slide rail and a sliding frame. The surface of the sliding frame near the column is equipped with a slider, which is slidably connected to the slide rail. A scraper is connected between the sliding frames. The column is connected to the scraper through the sliding frame. At the same time, the two columns form an independent support frame and have no physical connection with the turning machine body. The device can be used in conjunction with the turning machine or can be used independently for top skin scraping. It completely avoids the interference of the turning radius of the turning machine, reduces the installation height of the device to only cover the thickness of the billet, shortens the movement stroke, and improves the overall operating cycle time, thereby improving production efficiency.
[0007] Furthermore, it also includes a rack mounted on the surface of the column, which is meshed with a drive gear, and a motor mounted on the scraper to drive the drive gear. The motor is located in the middle of the scraper to further reduce the risk of off-center loading.
[0008] Furthermore, a single motor synchronously drives the gears on both sides via a through-type transmission shaft, eliminating the risk of asynchronous movement on both sides. The reducer's torque-increasing characteristics are matched to the scraping load, and its constant torque output characteristics ensure stable scraping speed, especially in the low-speed scraping section, avoiding scraper vibration caused by sudden load changes.
[0009] Furthermore, the sliding frame is connected to a bearing housing, the drive gear is connected to a connecting shaft, and a transmission shaft is also included. The connecting shaft passes through the bearing housing and is connected to one end of the transmission shaft, while the other end of the transmission shaft is connected to a motor. The motor in the middle simultaneously drives the transmission shafts at both ends, causing the drive gears to rotate synchronously and move the sliding frame along the slide rail. At the same time, the sliding frame drives the scraper and the top scraper on the scraper to move together. The single motor driving the dual gears eliminates the risk of power asynchrony.
[0010] Furthermore, the scraper frame surface is provided with multiple baffles, which are evenly distributed along the scraper frame surface.
[0011] Furthermore, the baffle is L-shaped, U-shaped, or arc-shaped, partially wrapping around the drive shaft from the side or top.
[0012] Furthermore, a scraper fixing frame is provided on the scraper frame. The scraper fixing frame adopts a box-type welded structure and is equipped with reinforcing ribs to improve bending stiffness and further suppress scraping chatter.
[0013] Furthermore, the box-shaped frame reinforced with welded stiffeners forms a high-torsional-resistance matrix, with a significantly higher moment of inertia than the traditional L-shaped support. The scraping reaction force is evenly distributed to the sliding frame through the frame, suppressing the pitching vibration of the scraper during operation, ensuring uniform contact between the blade and the billet along its entire length, and improving the integrity of top skin removal.
[0014] Furthermore, the scraper holder is connected to the top scraper.
[0015] Furthermore, an adjusting bolt is installed between the top scraper and the scraper fixing bracket. The adjusting bolt adopts a precision trapezoidal thread and, together with the scale ring, enables precise adjustment of the distance between the scraper and the brick blank.
[0016] Furthermore, limiters are installed on the surface of the column, located at both ends of the slide rail, and stops are provided on the surface of the sliding frame; the limiters provide deceleration signals to the control system to achieve flexible end-point stopping; the hardened steel stops serve as the final stop, withstand unexpected overtravel impacts, and establish fault-safe redundancy.
[0017] Furthermore, the slide rail and rack are arranged in parallel, which eliminates internal stress caused by motion interference. The slide rail provides guidance, while the rack is dedicated to power transmission. This clear division of labor avoids system jamming and further improves response speed.
[0018] Compared with the prior art, this utility model has the following advantages: the two columns form a stable vertical guide reference, allowing the scraping system to be arranged close to the billet. The column surface is equipped with a slide rail and also includes a sliding frame. The surface of the sliding frame near the column is provided with a slider, which is slidably connected to the slide rail. A scraping frame is connected between the sliding frames. The column is connected to the scraping frame through the sliding frame. At the same time, the two columns form an independent support frame and have no physical connection with the turning machine body. The device can be used in conjunction with the turning machine or can be used independently for top skin scraping. The working path of this device does not overlap with the turning path of the turning machine. When working simultaneously with the turning machine, there will be no path interference. The installation height of the device is reduced to only need to cover the thickness of the billet, shortening the movement stroke and improving the overall operating cycle, thereby improving production efficiency.

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0049] The application principle of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0050] Example 1
[0051] like Figure 1-2As shown in Figure 4-7, a top skin removal device for a semi-finished product turning machine includes two columns 1. A slide rail 2 is mounted on the surface of each column 1. A sliding frame 4 is also included. A slider 3 is provided on the surface of the sliding frame 4 near the column 1. The slider 3 is slidably connected to the slide rail 2. A scraper 9 is connected between the sliding frames 4. The columns 1 are connected to the scraper 9 via the sliding frames 4. Simultaneously, the two columns 1 form an independent support frame, without physical connection to the turning machine body. The device can be used in conjunction with the turning machine or independently for top skin removal, completely avoiding interference from the turning radius of the turning machine. This reduces the device's installation height to only need to cover the thickness of the blank, shortens the movement stroke, and improves the overall operating cycle time, thereby increasing production efficiency.
[0052] Example 2
[0053] like Figure 1-7 As shown, based on Embodiment 1, a top skin removal device for a semi-finished product turning machine further includes a rack 6 mounted on the surface of the column 1, the rack 6 being meshed with a drive gear 5, and a motor 8 mounted on the scraper 9 to drive the drive gear 5. The motor 8 is located in the middle of the scraper 9 to further reduce the risk of off-center loading.
[0054] The sliding frame 4 is connected to a bearing seat 13, the drive gear 5 is connected to a connecting shaft 16, and also includes a transmission shaft 7. The connecting shaft 16 passes through the bearing seat 13 and is connected to one end of the transmission shaft 7. The other end of the transmission shaft 7 is connected to a motor 8. The motor 8, which is located in the middle, drives the transmission shafts 7 at both ends simultaneously, so that the drive gear 5 rotates synchronously, causing the sliding frame 4 to move along the slide rail 2. At the same time, the sliding frame 4 drives the scraper 9 and the top scraper 10 on the scraper 9 to move together. The single motor 8 drives the double gears to eliminate the risk of power asynchrony.
[0055] The scraper 9 is provided with a plurality of baffles 12, which are evenly distributed along the surface of the scraper 9.
[0056] The baffle 12 is L-shaped, U-shaped or arc-shaped, and partially wraps around the drive shaft 7 from the side or top.
[0057] The scraper frame 9 is equipped with a scraper fixing frame 14. The scraper fixing frame 14 adopts a box-type welded structure and is equipped with reinforcing ribs to improve bending stiffness and further suppress scraping chatter.
[0058] The scraper holder is connected to the top scraper 10.
[0059] Example 3
[0060] like Figure 1-11As shown, a top skin removal device for a semi-finished product turning machine includes two columns 1, with slide rails 2 mounted on the surface of each column 1. It also includes a sliding frame 4, with a slider 3 on the surface of the sliding frame 4 near the column 1. The slider 3 is slidably connected to the slide rails 2. A scraper 9 is connected between the sliding frames 4. The columns 1 are connected to the scraper 9 via the sliding frames 4. The two columns 1 form an independent support frame, without physical connection to the turning machine body. The device can be used in conjunction with the turning machine or independently for top skin removal, completely avoiding interference from the turning radius of the turning machine. This reduces the installation height of the device to only cover the thickness of the blank, shortens the movement stroke, and increases the overall operating cycle time, thereby improving production efficiency.
[0061] It also includes a rack 6 mounted on the surface of the column 1, the rack 6 being meshed with a drive gear 5, and a motor 8 mounted on the scraper 9 to drive the drive gear 5. The motor 8 is located in the middle of the scraper 9 to further reduce the risk of off-center loading.
[0062] The sliding frame 4 is connected to a bearing seat 13, the drive gear 5 is connected to a connecting shaft 16, and also includes a transmission shaft 7. The connecting shaft 16 passes through the bearing seat 13 and is connected to one end of the transmission shaft 7. The other end of the transmission shaft 7 is connected to a motor 8. The motor 8, which is located in the middle, drives the transmission shafts 7 at both ends simultaneously, so that the drive gear 5 rotates synchronously, causing the sliding frame 4 to move along the slide rail 2. At the same time, the sliding frame 4 drives the scraper 9 and the top scraper 10 on the scraper 9 to move together. The single motor 8 drives the double gears to eliminate the risk of power asynchrony.
[0063] The scraper 9 is provided with a plurality of baffles 12, which are evenly distributed along the surface of the scraper 9.
[0064] The baffle 12 is L-shaped, U-shaped or arc-shaped, and partially wraps around the drive shaft 7 from the side or top.
[0065] The scraper frame 9 is equipped with a scraper fixing frame 14. The scraper fixing frame 14 adopts a box-type welded structure and is equipped with reinforcing ribs to improve bending stiffness and further suppress scraping chatter.
[0066] The scraper holder is connected to the top scraper 10.
[0067] An adjusting bolt 15 is provided between the top scraper 10 and the scraper fixing frame. The adjusting bolt 15 adopts a precision trapezoidal thread and, together with the scale ring, enables precise adjustment of the scraper.
[0068] Limiters 11 are installed on the surface of the column 1, and the limiters 11 are located at both ends of the slide rail 2. Blocks are provided on the surface of the sliding frame 4.
[0069] The slide rail 2 and rack 6 are arranged parallel to each other, which eliminates internal stress caused by motion interference. The slide rail provides guidance, while the rack is dedicated to power transmission. This clear division of labor avoids system jamming and further improves response speed.
[0070] like Figure 8 As shown, when the top skin removal device works in conjunction with the turning machine, the sliding frame 4 and the scraper frame 9 are initially positioned at the upper end of the guide rail 2. When the brick blank is placed on the bottom plate of the turning machine and the turning machine begins its turning operation, the motor 8 starts, driving the transmission shaft 7 to rotate, thereby causing the connecting shaft 16 to rotate in the bearing seat 13. This causes the drive gear 5 to rotate and move along the rack 6, driving the slider 3 on the sliding frame 4 to move along the slide rail 2, and driving the scraper frame 9 to move to the position shown. Figure 9 The standby position shown is near the middle of column 1, waiting for the flipping machine to complete the flipping.
[0071] like Figure 10 As shown, after the turning machine finishes turning, the motor 8 starts immediately, driving the sliding frame 4 to move towards the lower end of the column 1, which in turn drives the top scraper 10 to remove the top skin of the brick blank.
[0072] like Figure 11 As shown, after scraping is completed, the motor 8 drives the drive gear 5 to move the sliding frame 4 and the hanging frame 9 back to the standby position to wait for the next batch of scraping.
