Description

Technical Field

[0001] This utility model relates to the field of lightweight wall material production technology, and in particular to an automated production line for lightweight wall materials. Background Technology

[0002] Lightweight wall materials are widely used building materials in modern architecture, offering advantages such as light weight, environmental friendliness, and energy efficiency. They effectively reduce building weight, improve space utilization, and lower energy consumption. Common lightweight wall materials include lightweight bricks, aerated concrete panels, and gypsum boards. Gypsum board, as a type of lightweight wall material, primarily uses building gypsum as its raw material. Paper-faced gypsum board is a common type, lightweight and easy to process; it can be sawed, nailed, and planed to meet various shaping needs and is often used for interior partitions and ceilings. The gypsum board production process mainly includes raw material mixing, hydraulic molding, drying, and automatic cutting. Existing gypsum board production lines typically use multi-layer drying kilns to dry the molded gypsum boards. However, multi-layer drying kilns have multiple drying layers, and the resistance encountered by hot air during its ascent and descent makes it difficult to distribute temperature and humidity evenly between layers. The lower layers closer to the heat source have higher temperatures and lower humidity, while the upper layers farther from the heat source have lower temperatures and higher humidity. Within the same layer, areas near ventilation openings or hot air inlets differ in temperature and humidity from areas further away, leading to inconsistent material drying and impacting product quality. Furthermore, multi-layer drying kilns typically have a certain height and relatively small spaces between layers, making material loading and unloading difficult and reducing the production efficiency of lightweight wall materials such as gypsum board.

[0003] Therefore, it is necessary to improve the existing production lines for lightweight wall materials such as gypsum board in order to overcome the shortcomings of the existing technology. Utility Model Content

[0032] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0033] The existing production process of lightweight wall material gypsum board mainly includes steps such as raw material mixing, hydraulic molding, drying, and automatic cutting. In the drying stage, existing gypsum board production lines typically use multi-layer drying kilns to dry the molded gypsum board. However, multi-layer drying kilns have multiple drying layers, and the resistance encountered by hot air during its ascent and descent makes it difficult to achieve uniform temperature and humidity distribution between layers. Lower layers closer to the heat source have higher temperatures and lower humidity, while upper layers farther from the heat source have lower temperatures and higher humidity. Within the same layer, areas near ventilation openings or hot air inlets also exhibit temperature and humidity differences compared to areas farther away, resulting in inconsistent drying levels and affecting product quality. Furthermore, multi-layer drying kilns typically have a certain height, with relatively small spaces between layers, making material loading and unloading difficult and reducing the production efficiency of lightweight wall materials such as gypsum board.

[0034] Based on this, this application provides an automated production line for lightweight wall materials.

[0035] Example 1

[0036] like Figures 1-7 As shown in the figure, this embodiment provides an automated production line for lightweight wall materials, comprising:

[0037] A molding mechanism 1 is used to pressurize and mold wall material raw materials, and a discharge port is provided on the molding mechanism 1;

[0038] A tunnel drying oven 3 is located on one side of the discharge port of the forming mechanism 1. The tunnel drying oven 3 is provided with a drying inlet 32. A conveyor chain 6 is provided inside the tunnel drying oven 3. The conveyor chain 6 is arranged along the length direction of the tunnel drying oven 3. The conveyor chain 6 is provided with a snap-fit ​​position 63 for snapping the wall material.

[0039] A receiving structure 2 is provided between the drying inlet 32 ​​and the discharge port of the forming mechanism 1. A conveyor belt 22 is provided on the receiving structure 2. One end of the conveyor belt 22 is connected to the discharge port of the forming mechanism 1, and the other end is connected to the conveyor chain 6.

[0040] Specifically, in practical applications, the molding mechanism 1 of this application adopts a hydraulic pressure molding device. This device is equipped with a high-precision mold and uses a hydraulic system to provide stable pressure to pressurize and mold the wall material raw material entering the mold. The discharge port of the molding mechanism 1 is located at the bottom of the device, and an electric gate is installed at the discharge port to control the discharge speed and rhythm of the molded wall material.

[0041] The tunnel drying oven 3 has a rectangular structure, with two parallel conveyor chains 6 arranged along its length inside. The conveyor chains 6 are driven by a motor and rotate cyclically through the cooperation of sprockets and chains. In one embodiment, U-shaped locking positions 63 are evenly spaced on the conveyor chains 6. The dimensions of these locking positions 63 are adapted to the shape of the formed wall material, enabling them to securely hold the wall material and prevent it from falling off during transport. The drying inlet 32 ​​of the tunnel drying oven 3 is located near the discharge port of the forming mechanism 1, and the height of the drying inlet 32 ​​is the same as the height of the discharge port of the forming mechanism 1, facilitating the transport of the wall material.

[0042] The receiving structure 2 adopts a frame structure, on which a conveyor belt 22 is installed. The conveyor belt 22 is a high-temperature resistant and high-strength mesh belt. One end of the conveyor belt 22 is connected to the discharge port of the forming mechanism 1 through an inclined transition plate. The inclination angle of the transition plate is 15°, which facilitates the smooth sliding of the formed wall material onto the conveyor belt 22. The other end of the conveyor belt 22 is connected to the conveyor chain 6 inside the tunnel drying oven 3, and a guide plate is provided at the connection point to ensure that the wall material can be accurately transferred from the conveyor belt 22 to the locking position 63 of the conveyor chain 6.

[0043] In the actual production process, after the wall material raw material enters the mold of the molding mechanism 1, the hydraulic system is activated to pressurize and mold the raw material. After molding, the wall material slides from the discharge port onto the conveyor belt 22 of the receiving structure 2 under the control of the electric gate. The conveyor belt 22 transports the wall material to the drying inlet 32 ​​of the tunnel drying oven 3, and accurately transfers the wall material to the clamping position 63 of the conveyor chain 6 through the guide plate. Then the conveyor chain 6 drives the wall material to move inside the tunnel drying oven 3. After the set drying time, the dried wall material is output from the other end of the tunnel drying oven 3.

[0044] The aforementioned automated production line for lightweight wall materials, in practical use, utilizes a receiving structure 2 between the discharge port of the forming mechanism 1 and the drying inlet 32 ​​of the tunnel drying oven 3. A conveyor belt 22 is installed on the receiving structure 2, allowing the formed wall material to be directly transported from the forming mechanism 1 to the tunnel drying oven 3 for drying. This eliminates the need for manual handling or intermediate storage, shortening the production cycle and reducing time wasted due to manual intervention and material transfer, thus significantly improving the production efficiency of lightweight wall materials. Furthermore, the tunnel drying oven 3 simplifies the drying process. The locking positions 63 on the conveyor chain 6 within the oven 3 stably hold the wall material, ensuring uniform heat distribution and preventing uneven drying caused by stacking or irregular placement. Simultaneously, the tunnel drying oven 3 precisely controls the internal temperature and humidity, providing a suitable drying environment for the wall material and ensuring sufficient evaporation of moisture, thereby enhancing the drying effect. Good drying results can reduce quality problems such as deformation and cracking of wall materials caused by residual moisture during subsequent use, thereby improving the quality and stability of wall materials.

[0045] In a specific embodiment, the tunnel drying oven 3 includes a drying body 31, on which a drying inlet 32 ​​and a drying outlet are provided. The drying outlet is located at the end of the drying body 31 away from the drying inlet 32. The conveyor chain 6 is disposed between the drying inlet 32 ​​and the drying outlet.

[0046] Two conveyor chains 6 are provided in the drying body 31, and the two conveyor chains 6 are arranged in parallel.

[0047] Furthermore, the conveyor chain 6 includes two opposing chain belts 61 and a drive device, the drive device driving the chain belts 61 to rotate;

[0048] Each of the chain belts 61 is provided with a locking block 62, and the locking position 63 is formed between the locking blocks 62 of the two chain belts 61.

[0049] In this embodiment, the conveyor chain 6 consists of a drive device and two opposing chain belts 61. The drive device includes a servo motor, a reducer, and a sprocket assembly. The servo motor is connected to the sprocket assembly through the reducer, allowing for precise adjustment of the chain belt 61's running speed. Each chain belt 61 is made of high-strength stainless steel. L-shaped locking blocks 62 are welded to each chain belt 61 every 30cm. The opposing locking blocks 62 of the two chain belts 61 form a U-shaped locking position 63. The width of the locking position 63 is 5mm wider than the width of the formed wall material, ensuring a secure clamping of the wall material while preventing excessive tightness that could damage its surface. The two parallel conveyor chains 6 form a specific spacing within the drying body 31, ensuring that the wall material is fully exposed to hot air from all sides during the drying process, increasing the heat exchange area and preventing incomplete drying in certain areas due to stacking.

[0050] Specifically, the drying body 31 is provided with a plurality of drying zones, and each of the drying zones is arranged in the drying body 31 along the length direction of the conveyor chain 6;

[0051] Each of the drying zones includes heating boxes 33 located on the upper and lower sides of the conveyor chain 6. Each heating box 33 is equipped with a heating rod 35. Each heating box 33 is connected to the area of ​​the conveyor chain 6 through a uniform air distribution plate 36.

[0052] The heating box 33 is also equipped with a hot air blower 34, which is positioned towards the conveyor chain 6.

[0053] Furthermore, each of the heating boxes 33 is equipped with a temperature sensor for detecting temperature.

[0054] In practical applications, the heating box 33 is made of double-layer stainless steel, with six S-shaped ceramic heating rods 35 evenly arranged inside. Each heating rod 35 has a power of 2kW, and the heating power can be adjusted through a temperature control system. A honeycomb-shaped air distribution plate 36 is installed on the side of the heating box 33 facing the conveyor chain 6. The air distribution plate 36 is densely covered with ventilation holes with a diameter of 8mm, which can evenly guide the hot air inside the heating box 33 to the wall material on the conveyor chain 6. In addition, each heating box 33 is equipped with an axial flow hot air fan 34 on top. The air outlet of the hot air fan 34 is perpendicular to the conveyor chain 6, and the wind speed can be adjusted from 5-20m / s, which can accelerate the circulation of hot air and enhance the convective heat transfer effect on the wall material.

[0055] The combined design of the heating box 33 and the hot air blower 34, along with the air distribution plate 36, can form a highly efficient hot air circulation system within the drying oven. The hot air blower 34 forces convection to accelerate the flow of hot air, allowing the hot air to quickly and evenly contact the wall material surface, significantly improving heat exchange efficiency.

[0056] By dividing the drying unit 31 into multiple drying zones, each zone is independently equipped with a heating chamber 33, a hot air blower 34, and a temperature sensor. Different temperature profiles can be set in stages according to the drying process requirements of the wall material. For example, high temperature is used initially to rapidly evaporate surface moisture, and then the temperature is lowered later to allow internal moisture diffusion, preventing cracking of the wall material due to sudden temperature changes. The temperature sensor provides real-time data feedback, and combined with the PLC system, the heating equipment is dynamically adjusted, ensuring high temperature control accuracy and a highly efficient and stable drying process. Compared to traditional single-heating modes, this significantly improves drying quality and efficiency. Furthermore, segmented temperature control avoids surface cracking due to excessively high temperatures or internal moisture residue due to insufficient temperatures, significantly improving the drying quality and yield of lightweight wall materials.

[0057] In a preferred embodiment, both the drying inlet 32 ​​and the drying outlet are provided with baffles 4, the baffles 4 are slidably disposed on the drying body 31, and the drying body 31 is provided with a driving cylinder 5 for driving the baffles 4 to slide.

[0058] During production line operation, when the wall material is about to enter the tunnel drying oven 3, the PLC control system sends a signal, causing the piston rod of the drive cylinder 5 at the drying inlet 32 ​​to retract, driving the baffle 4 to slide upward along the linear guide rail, exposing the drying inlet 32. The conveyor belt 22 of the receiving structure 2 then feeds the wall material into the oven. Once the wall material has fully entered, the piston rod of the drive cylinder 5 extends, pushing the baffle 4 to reset and closing the drying inlet 32. Similarly, when the wall material completes drying and reaches the drying outlet, the baffle 4 at the outlet opens under the action of the drive cylinder 5, and the baffle 4 closes quickly after the wall material is output.

[0059] The drying inlet 32, in conjunction with the sliding baffle 4 at the outlet, drives the cylinder 5 to quickly open and close when wall materials enter or exit, effectively reducing the leakage of hot air from the furnace and the entry of cold air from the outside. This structure maintains a stable drying environment inside the furnace, preventing uneven drying of the wall materials due to temperature changes, thereby improving the stability of product quality. The excellent sealing performance reduces heat loss within the drying furnace, lowering the workload of the heating equipment.

[0060] Furthermore, the drying body 31 is also equipped with a dust removal system 7, which includes an induced draft fan 72 and a dust collection box. The dust collection box is located on one side of the conveyor chain 6, and its side wall has a connecting hole 71 that communicates with the area where the conveyor chain 6 is located. One side of the dust collection box is connected to the induced draft fan 72. The dust removal system 7 can promptly remove debris and dust generated during the drying process, preventing these impurities from adhering to the surface of the wall material and preventing quality problems such as defects and holes on the surface of the wall material due to dust pollution. The dust removal system 7 collects and discharges the dust generated during the drying process from the workshop, effectively reducing the dust concentration in the workshop, improving the working environment for workers, and reducing the harm of dust to workers' health.

[0061] Furthermore, the receiving structure 2 includes a receiving frame 21, which is disposed between the forming mechanism 1 and the tunnel drying oven 3, and the conveyor belt 22 is disposed on the receiving frame 21;

[0062] The receiving frame 21 is also provided with a baffle plate 23, which is located near the end of the conveyor belt 22 that is connected to the conveyor chain 6.

[0063] Specifically, in this embodiment, the receiving frame 21 achieves precise height adjustment via adjustable anchor bolts, ensuring seamless connection between the conveyor belt 22 and the discharge port of the forming mechanism 1, and the conveyor chain 6 of the tunnel drying oven 3, preventing the wall material from falling or getting stuck during transmission due to height differences. The conveyor belt 22 is made of high-strength polyester mesh belt, tensioned and driven by rollers at both ends, which are driven by a geared motor. A transverse anti-slip rubber strip can also be installed on the upper surface of the conveyor belt 22 every 50 cm to increase the friction between the conveyor belt 22 and the wall material, preventing the wall material from slipping during transmission. The baffle plate 23 can be driven by a baffle cylinder, allowing the baffle plate 23 to enter or leave the conveyor belt 22, thereby achieving orderly control of the flow of wall material on the conveyor belt 22.

[0064] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0065] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
