[0002] In the production of blue tiles, raw material feeding is a crucial step. Traditional feeding devices mostly rely on conveyor belts, but this has several problems in practice: First, the raw materials for blue tiles are highly adhesive and easily stick to the surface of the conveyor belt. Existing devices mostly only have simple fixed scrapers for cleaning, which has limited effectiveness. Over time, residual material accumulates, affecting the normal operation of the conveyor belt. Second, material splashes out from both sides of the conveyor belt during transport, wasting raw materials and polluting the environment. Finally, the scraper angle of existing cleaning devices is fixed and cannot be adjusted according to the characteristics of the material, resulting in either incomplete cleaning or excessive wear on the conveyor belt.

[0018] 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.

[0019] Please see Figure 1-10This utility model provides a new technical solution: a material feeding device for producing blue tiles, including a frame 13 and a first control cabinet 6. The frame 13 is the overall support frame of the device, bearing all components of the device. A conveyor belt assembly 1 is fixedly connected to the upper surface of the frame 13. The conveyor belt assembly 1 includes a belt, baffles, and guide rollers. The belt is sleeved on the drive roller 3 and the driven roller 2, forming the main working surface for material transmission. The drive roller 3, a cylindrical drive drum, is rotatably connected to the inner wall of the conveyor belt assembly 1, converting the torque of the first motor 4 into the traction force of the belt. The driven roller 2, a cylindrical drum, is rotatably connected to the inner wall of the conveyor belt assembly 1, via bearings. The first motor 4 is rotatably connected to the frame 13. Its main function is to support the belt and change its direction. It works with the drive roller 3 to tension the belt and ensure its stable operation. The outer surface of the frame 13 is fixedly connected to the first motor seat 5. The first motor seat 5 is used to withstand the vibration of the first motor 4 during operation. The upper surface of the first motor seat 5 is fixedly connected to the first motor 4. Its output shaft is directly connected to the drive roller 3 to provide a power source for the entire conveyor belt assembly 1. The first control cabinet 6 is electrically connected to the first motor 4. The first control cabinet 6 is used to control the start, stop, speed adjustment and overload protection of the first motor 4. The conveyor belt assembly 1 consists of a belt, baffles and rollers. The outer surface of the frame 13 is equipped with a cleaning device. The cleaning device includes a primary scraper 7, which is used to scrape off most of the adhering material. The primary scraper 7 is fixedly connected to the baffle of the conveyor belt assembly 1 and is in contact with the outer surface of the conveyor belt assembly 1. A tertiary scraper 9 is rotatably connected inside the frame 13 via a shaft. The tertiary scraper 9 is used for deep cleaning of residues on the belt surface. The tertiary scraper 9 consists of a blade head fixedly connected to the blade body and is in contact with the outer surface of the belt. A secondary scraper 8 is fixedly connected inside the frame 13. In addition to scraping off residues on the sides of the belt, the elongated structure of the secondary scraper 8 can also limit the lateral deviation of the belt and play a guiding role. The secondary scraper 8 is located in the middle section of the belt and is in contact with the side of the belt. A secondary scraper guide groove 20 is opened on the outer surface of the secondary scraper 8 to guide the flow of the secondary scraper. The trough 20 guides the belt side residue scraped by the secondary scraper into the collection hopper to prevent residue from accumulating on the belt side or inside the frame. The outer surface of the frame 13 is fixedly connected to the second motor seat 11. The second motor seat 11 prevents the second motor 10 from shifting when it vibrates during operation. The upper surface of the second motor seat 11 is fixedly connected to the second motor 10. The second motor 10 is used to provide power for the angle adjustment of the third-stage scraper 9. The second motor 10 is fixedly connected to the third-stage scraper 9. The right side of the second motor seat 11 is fixedly connected to the second control cabinet 12. The second control cabinet 12 is electrically connected to the second motor 10. The second control cabinet 12 is used to receive commands and control the rotation angle and torque of the second motor 10, thereby realizing the dynamic adjustment of the working posture of the third-stage scraper 9. The outer surface of the frame 13 is provided with a guardrail slot 15. The guardrail slot 15 allows the guardrail 16 to slide up and down along it and is finally fixed by bolts. The guardrail 16 is slidably connected to the outer surface of the guardrail slot 15. The guardrail 16 fits against both sides of the conveyor belt assembly 1. The guardrail 16 is used to prevent materials from splashing out from the side during the conveying process and to ensure production safety. The frame 13 has a collection hopper slot 19 inside, which guides and supports the collection hopper 14. The collection hopper 14 is slidably connected to the outer surface of the collection hopper slot 19. The collection hopper 14 is used to collect the residual material scraped off by the scraper, which is convenient for centralized cleaning and recycling. A discharge hopper 17 is fixedly provided at the upper end of the belt. The function of the discharge hopper 17 is to hold the material to be conveyed. An anti-arching component 18 is fixedly connected to the outer surface of the discharge hopper 17. By generating vibration at a specific frequency, the arching phenomenon formed by the material in the discharge hopper 17 is destroyed, ensuring smooth material discharge. The anti-arching component 18 includes a high-frequency vibration dispersion unit, a low-frequency electromagnetic knocker, and a vibration linkage controller.

[0020] Working principle: When using this device, connect to an external power supply and start the first control cabinet 6 to control the output end of the first motor 4 to rotate. The rotation of the output end of the first motor 4 drives the active roller 3 to rotate. When the active roller 3 rotates, it drives the driven roller 2 to rotate synchronously through the conveyor belt assembly 1, so that the belt starts to drive. At this time, the discharge hopper 17 starts to discharge material, and the anti-arching assembly 18 on the surface of the discharge hopper 17 starts to vibrate to prevent the discharge hopper 17 from getting blocked. Start the second control cabinet 12, and the second motor 10 provides power to the rotating shaft of the third-stage scraper 9. The second control cabinet 12 controls the rotating shaft through the second motor 10, thereby controlling the third-stage scraper 9. Thus, the second motor 10 can realize the dynamic adjustment of the contact angle between the third-stage scraper 9 and the belt. This design can not only dynamically adjust the angle according to the state of clay residue to reduce the wear of the belt and the scraper, but also has the functions of quickly replacing the blade head and conveniently cleaning the clay residue on the blade head. When the clay material moves with the belt to the first-level scraper 7, the scraping surface of the first-level scraper (7) can first remove the thick layer of clay residue on the surface of the conveyor belt assembly (1), and at the same time assist the material to flow smoothly. When the conveyor belt assembly 1 carries the clay residue and passes through the second-level scraper 8, the second-level scraper 8 can scrape off the clay residue on the side of the conveyor belt assembly 1 and fall directly into the collection hopper 14 through the second-level scraper guide groove 20, so as to avoid the clay residue accumulating on the side of the belt and being unable to be cleaned. The long strip design of the second-level scraper 8 can prevent the belt from shifting during transportation. When the conveyor belt assembly 1 carries the clay residue and passes through the third-level scraper 9, the third-level scraper 9 can more thoroughly remove the clay residue on the surface of the conveyor belt assembly 1 by means of the linkage and cooperation with the second motor 10.

[0021] Furthermore, the guardrail 16 is fixed in the guardrail slot 15 of the frame 13 by bolts, so that the guardrail 16 can be quickly disassembled. The guardrail 16 can block the clay clumps thrown out from the side of the belt during the conveying process, avoid raw material splashing and polluting the workshop environment, and ensure production safety.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0023] Example 1: Raw materials with low viscosity and certain fluidity: Please see Figure 8 The third-level scraper 9 has been replaced with a blade with a guide groove; When producing lightweight insulated tiles, a tile building materials factory needs to add water-based adhesive raw materials with low viscosity and high fluidity. When using traditional flat scraper, the raw material splashes up to 15% along both sides of the scraper, which not only contaminates the machine frame 13 and the ground, but also results in material waste and low utilization rate. In addition, the splashed raw material is easy to adhere to the surface of the drive roller 3 and the driven roller 2, causing belt misalignment. At this time, the blade of the third-stage scraper 9 is replaced with a blade with a guide groove. The replaced blade has a guide groove on its front side, while retaining the drive connection with the second motor 10. The arc-shaped guide channel can effectively collect fluid raw materials, reduce splashing rate, and eliminate the need for frequent shutdowns for cleaning; the guide channel can directionally guide the raw materials to the end collection port and then flow into the collection hopper 14, thereby improving the raw material recycling rate. Furthermore, the blade with the guide groove has the same mounting interface and connection dimensions as the original blade, and can be directly mounted on the output shaft of the second motor 10 and the support structure of the second motor seat 11; the transmission load of the second motor 10 can also be adapted, and it can also be completely placed into the internal space of the existing frame 13. Moreover, because the arc-shaped groove surface is smooth and does not easily accumulate material, the maintenance time is low; the guide structure makes the raw material recycling process more efficient, shortens the residual material processing time and improves efficiency.

[0024] Example 2: Special raw materials with extremely high viscosity: Please see Figure 9 The blade of the third-stage scraper 9 has been replaced with a curved blade. When producing high-density roofing tiles, a tile factory needs to process a special clay with extremely high viscosity. When using a traditional straight scraper, the large contact area with the belt and high scraping resistance cause the second motor 10 to be overloaded and the overheat protection to be activated frequently. In addition, a large amount of clay accumulates on the front of the straight scraper, forming a sticky scraper, which requires frequent machine stops for manual cleaning, seriously affecting the continuity of production. At this time, the blade of the third-stage scraper 9 is replaced with an arc-shaped blade. The working edge of the replaced blade is a continuous and smooth arc surface. The arc-shaped blade design significantly reduces the contact area with the belt surface, greatly reducing scraping resistance, significantly reducing overheating problems, and ensuring stable operation; the arc-shaped surface is less prone to material accumulation, virtually eliminating blade clogging and ensuring continuous and stable operation of the equipment. Furthermore, the mounting base and connection holes of the curved blade are consistent with the original blade, and it can be directly replaced and installed on the second motor seat 11 without any modification to the mechanical structure; the curved blade is lightweight and its overall strength meets the requirements, resulting in less impact on the starting and stopping inertia of the second motor 10; the curved structure makes the scraper more evenly stressed and extends its service life by 2 times. Furthermore, the curved blade makes cleaning easier and shortens the time required for a single maintenance cycle; the reduced operating load lowers the equipment's energy consumption, making it suitable for continuous production scenarios involving highly viscous raw materials.

[0025] Example 3: Raw materials containing granular additives: Please see Figure 10 The third-level scraper 9 was replaced with a brush; A tile factory needs to process raw materials containing granular additives during production. Traditional rigid scraper cleaning presents the following problems due to the rolling nature of the granular material: First, the granular material rolls along the belt surface under the scraper's thrust, resulting in low cleaning efficiency; second, hard particles cause abrasion between the scraper and the belt, accelerating belt surface wear; and third, granular material easily splashes and scatters from both sides of the scraper, causing material waste. To address this, the three-stage scraper 9 is replaced with a brush. The working part of the replaced three-stage scraper 9 is made of wear-resistant nylon bristles arranged at an angle. The bristles arranged at an angle achieve a sweeping effect, penetrating deep into the microstructure of the belt surface to effectively sweep away particulate materials, greatly reducing the residue rate of particulate materials. The flexible nature of the bristles avoids hard abrasion, reducing the monthly wear of the belt and extending its service life. The angled arrangement of the bristles also acts as a guide, gathering particulate materials towards the center and preventing them from splashing to the sides. Furthermore, the installation interface and connection dimensions of the brush-type blade are completely consistent with the original blade, and it can be directly adapted to the output shaft of the second motor 10; the flexible contact of the bristles reduces the load on the second motor 10 and reduces energy consumption; the directional sweeping effect of the bristles on particulate materials can increase the recycling rate of raw materials, making it particularly suitable for cleaning scenarios containing particulate additives.
