Description

Technical Field

[0001] This invention relates to the field of sheet metal production technology, and in particular to an automated felting production process for multi-layer sheet metal - daily-use ceramic slat trays. Background Technology

[0002] With the rapid development and increasing automation of the daily-use ceramics manufacturing industry, the need for protection of ceramic blanks during production, storage, and transportation is becoming increasingly important. In automated production lines for daily-use ceramics, specialized slat pallets are required for the storage and support of ceramic blanks, especially to meet the need for separate storage of dry and wet ceramic blanks. Because ceramic blanks are relatively fragile and easily damaged by contact with hard materials, soft protective materials need to be laid on the surface of the slat pallets. Felt, as a material with good cushioning properties, is widely used for the protection of ceramic blanks. By covering the surface of wooden slats with felt, the ceramic blanks can be protected from damage by hard contact and the friction between the slats and the ceramic blanks can be increased, effectively preventing damage caused by collisions between ceramic blanks.

[0003] Currently, the production of felted slats is mainly done manually. The traditional process includes: first, cutting large-area plywood into slats of the required size using a saw blade workbench; then, setting up a cutting platform, manually securing bundles of felt to an I-beam frame, and having two workers pull the felt flat onto the workbench by rotating it; next, two workers work together, one placing the slats parallel to the felt, and using a utility knife to cut the felt to match the slat area; finally, two fixing methods are used: one is to apply glue to the slats with a brush, then flip the slats over and press them onto the felt to bond them, and finally nail the ends of the slats together with a pneumatic nail gun; the other is to directly nail the felt to the slats with a pneumatic nail gun. The entire manual production process takes about 3 minutes per slat, and each person can complete 75 slats in an eight-hour workday, with a labor cost of approximately 2.5-3 RMB per slat.

[0004] However, traditional manual methods for producing felt strips have numerous technical defects and problems. Firstly, production efficiency is low, labor costs are high, and the reliance on skilled manual labor makes it difficult to meet the demands of modern large-scale production. Secondly, uneven glue application is a significant issue; manual glue application makes it difficult to control the thickness and coverage area, resulting in weak bonding between the felt and the board, leading to separation and cracking, short lifespan of the felt strips, and increased product costs. Thirdly, the lack of standardization in manual operation leads to significant waste of glue and other materials, and the difficulty in standardizing operations results in inconsistent product quality, further increasing strip production costs. These technical problems severely restrict the automation development process in the daily-use ceramics industry, urgently requiring the development of an efficient, stable, and economical automated felt production process to replace traditional manual methods. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides an automated felting production process for multi-layer board-daily-use ceramic slat trays. Includes the following steps: Step 1: Place the 2.44m x 1.22m multi-layer plywood on the automatic conveyor platform of the automatic glue applicator. The automatic glue applicator will evenly apply cold-pressed glue to one side of the multi-layer plywood, with the glue thickness controlled at 0.1-0.2 mm. Step 2: The mechanical tension hand system automatically lays the felt sheet of the same size as the plywood onto the adhesive surface. The mechanical tension hand system includes 6 independent clamping points, which coordinate the movements to accurately position the felt. Step 3: The glued board and felt assembly are rolled in sections using 8 sets of rotating columns with a diameter of 200 mm. The rolling pressure is controlled at 0.5-1.0 MPa to form the initial felt board. Step 4: Place 90 preliminary felt boards into a cold press and cold press them for 6 hours at 5 standard atmospheres to allow the cold-pressed adhesive to fully cure. Step 5: Cut the cured felt board into strips of the required specifications using an electric saw cutting platform.

[0006] Furthermore, the amount of adhesive applied by the automatic glue applicator is controlled at 150-200 grams per square meter, with a glue coverage rate of over 95%.

[0007] Furthermore, the mechanical tension hand system controls the paving accuracy to ±2 mm, and the paving process is completed within 15 seconds.

[0008] Furthermore, among the eight sets of rotating columns, the pressure of the first set of rotating columns is set at 0.3 MPa, the pressure of the second to sixth sets of rotating columns gradually increases to 0.8 MPa, and the pressure of the last two sets of rotating columns is 0.5 MPa.

[0009] Furthermore, the cold press has a worktable area of ​​3 meters × 6 meters and a pressure distribution uniformity of over 98%.

[0010] Furthermore, the electric saw cutting platform adopts a CNC positioning system, with cutting accuracy controlled within ±0.5 mm. The specifications of the cut strips include length × width × thickness of 1.22 × 0.24 × 0.015 meters, 1.22 × 0.20 × 0.015 meters, 1.22 × 0.15 × 0.015 meters, or 1.22 × 0.10 × 0.015 meters.

[0011] An automated felt production equipment for implementing the aforementioned process includes an automatic glue applicator, a mechanical tension hand system, a rolling device, a cold press, and an automatic cutting platform connected in sequence. The automatic glue applicator is equipped with a precision screw pump glue supply system, the mechanical tension hand system is equipped with 6 independent clamping points, the rolling device includes 8 sets of rotating columns, the cold press has a maximum pressure of 10 MPa, and the automatic cutting platform adopts a servo motor driven screw transmission system.

[0012] The aforementioned equipment also includes an online detection device for real-time monitoring of adhesive thickness, paving accuracy, rolling pressure, and cold pressing parameters.

[0013] The beneficial effects of this invention are: 1. This invention completely solves the problem of low efficiency in traditional manual production of felt strips through a fully automated production process. The production time for each felt strip is reduced from 3 minutes to 15 seconds using traditional manual methods, increasing production efficiency by approximately 20 times. Each automated production line requires only 1 / 4 of a worker, while a worker can only complete 75 strips per day using traditional manual methods in eight hours. Labor costs are significantly reduced from 2.5-3 RMB per strip to 0.3 RMB, reducing overall production costs for enterprises by approximately 11%. Simultaneously, the orderly and uniform nature of automated production significantly saves on the consumption of raw materials such as glue, avoiding problems such as uneven glue application and improper glue usage that occur in manual operations, further controlling production costs.

[0014] 2. This invention employs a precise automated adhesive application system and a roller-curing process, ensuring an adhesive coating uniformity of over 95%. This achieves complete adhesive bonding between the felt and the board, eliminating the problems of uneven adhesive application and subsequent felt separation and cracking common in traditional manual production. This significantly extends the service life of the felt strips. Through cold-press curing, no hard objects are exposed on the strip surface, and the felt layer is completely fused with the wood board, providing an ideal soft protective surface for the ceramic body. This prevents damage to the ceramic body from contact with hard materials and increases the friction between the board and the ceramic body, effectively preventing collision damage. Compared to traditional manual production methods, this invention increases the utilization rate of high-quality ceramic bodies in daily-use ceramic production by at least 9%, significantly reducing the scrap rate of ceramic products.

[0020] This invention provides an automated felt-covering production process for multi-layer board-ceramic slat trays. This fully automated process completely solves the technical problems of low efficiency, high cost, and unstable quality inherent in traditional manual felt-covering slat production. The process employs an integrated production line with automatic gluing, automatic laying, automatic rolling, and automatic cutting, achieving a perfect combination of multi-layer boards and felt, providing high-quality protective tray slats for daily-use ceramic production.

[0021] Detailed Process Flow See Figure 1 , Figure 2 The automated felt production process of this invention includes six main steps: raw material preparation, automatic gluing, automatic laying, roller pressing, cold pressing and curing, and automatic segmentation. First, in the raw material preparation stage, high-quality multi-layer plywood is selected as the base material. The plywood's specifications are 2.44 meters in length and 1.22 meters in width, with the thickness determined according to customer requirements; common specifications include 1.5 cm and 1.2 cm thicknesses. The plywood's face sheet is made of natural wood veneer, possessing good mechanical strength and surface flatness, capable of withstanding various mechanical forces during subsequent processing. Simultaneously, felt sheets of the same size and specifications as the plywood are prepared. The felt material is selected from industrial felt with moderate density and good elasticity, ensuring sufficient cushioning and protection capabilities and good adhesive performance.

[0022] In the automated gluing process, multi-layer boards are precisely placed on the automatic conveyor platform of the automated gluing machine. This platform employs a precision positioning system to ensure the accurate placement of the boards. The automated gluing machine is equipped with a high-precision adhesive dispensing system that can automatically adjust the application thickness and coverage area of ​​the adhesive according to preset parameters. A special cold-press adhesive is used during the gluing process. This adhesive has excellent bonding strength and an appropriate open time, ensuring reliable bonding results under normal temperature conditions. The automated gluing system uses a precision spraying device to evenly apply adhesive to one side of the multi-layer board, controlling the adhesive thickness between 0.1-0.2 mm and achieving an adhesive coverage rate of over 95%, ensuring complete bonding between the subsequent felt and the board. After gluing, the board automatically flows to the next station. The entire gluing process is completely automated, avoiding problems such as uneven application and improper adhesive usage that may occur with manual operation.

[0023] The automated installation process employs an advanced mechanical tensioner system. This system precisely controls the tension and position of the felt, ensuring the felt remains flat and wrinkle-free during installation. The mechanical tensioner grips pre-cut felt sheets using a multi-point clamping method, and a precision servo motor drive system accurately lays the felt sheets onto the glued board surface. During installation, the system monitors the position and flatness of the felt in real time, automatically adjusting installation parameters through a feedback control system to ensure precise alignment and complete adhesion between the felt and the board. The entire installation process is completed within 15 seconds, with an installation accuracy controlled within ±2 mm, significantly improving production efficiency and product quality consistency.

[0024] The rolling bonding process is crucial for ensuring initial adhesion between the felt and the board. This process utilizes multiple sets of rotating columns for segmented rolling. The rotating columns, each 200 mm in diameter, are made of a special rubber material that provides sufficient pressure without damaging the felt surface. During rolling, the columns apply uniform pressure to the felt board at a constant speed and pressure, with the rolling pressure controlled between 0.5 and 1.0 MPa. This ensures the adhesive fully penetrates the felt fibers, forming reliable mechanical and chemical bonding. The rolling speed is controlled at 8-12 meters per minute, guaranteeing sufficient compaction while avoiding excessive pressure that could deform the felt. After the initial rolling treatment, the surface of the felt board is smooth, and a preliminary bond has formed between the felt and the board, laying a good foundation for subsequent cold-press curing.

[0025] The cold-press curing process is the most critical step in the entire process. This step utilizes a large hydraulic cold press for prolonged pressure curing. The cold press has a worktable area of ​​3 meters × 6 meters and can process 90 sheets of felt with a thickness of 0.015 meters simultaneously, greatly improving production efficiency. During the cold pressing process, the pressure is set at 5 standard atmospheres (approximately 0.5 MPa), and the pressing time is 6 hours. Under these conditions, the cold-pressed adhesive can be completely cured, forming a strong and durable adhesive layer. The cold press is equipped with a precise pressure control system and temperature monitoring system, which can monitor various parameters during the pressing process in real time to ensure the consistency and reliability of the curing effect. During the cold pressing process, the adhesive is evenly distributed under pressure, penetrating into every fiber of the felt, forming a strong three-dimensional network structure, resulting in an unprecedented level of bonding strength between the felt and the board.

[0026] The automated segmentation process utilizes a high-precision electric saw cutting platform equipped with a CNC positioning system and automated operating procedures. This platform can automatically segment the board into strips of different specifications according to customer needs. The cutting platform uses carbide saw blades with a diameter of 500 mm and 120 teeth, achieving high-quality cutting results. During the cutting process, the system automatically positions and cuts according to a preset cutting program. Common strip specifications include length × width × thickness of 1.22 × 0.24 × 0.015 meters, 1.22 × 0.20 × 0.015 meters, 1.22 × 0.15 × 0.015 meters, and 1.22 × 0.10 × 0.015 meters, among others. Cutting accuracy is controlled within ±0.5 mm, resulting in a smooth, flat cut surface free of burrs and tears. After cutting, the surface of the strips has no exposed hard objects; the felt layer is completely fused with the board, forming an ideal soft protective surface.

[0027] The automated production line of this invention mainly includes core equipment such as an automatic glue applicator, a mechanical tension hand system, a rolling device, a cold press, and an automatic cutting platform. The automatic glue applicator uses a precision screw pump glue supply system, with glue flow control accuracy reaching ±2%, and the glue application width adjustable within the range of 0.5-2.5 meters, while the glue application thickness is controlled within the range of 0.05-0.5 millimeters. The mechanical tension hand system is equipped with 6 independent clamping points, each with independently adjustable clamping force, achieving tension control accuracy of ±5%. The rolling device contains 8 sets of rotating columns, each with independently adjustable pressure, achieving rolling uniformity of over 95%. The cold press has a maximum pressure of up to 10 MPa, with worktable flatness controlled within 0.1 millimeters and pressure distribution uniformity exceeding 98%. The automatic cutting platform uses a high-precision lead screw transmission system driven by a servo motor, achieving a positioning accuracy of ±0.1 millimeters, and a cutting speed adjustable within the range of 5-50 meters per minute.

[0028] To ensure the stability and consistency of product quality, this invention establishes a comprehensive quality control system. Regarding raw material control, rigorous quality inspections are conducted on incoming multilayer boards and felts, including testing for dimensional accuracy, surface quality, and mechanical strength. For production process control, online monitoring devices are installed at each stage to monitor key process parameters in real time, such as adhesive thickness, installation accuracy, rolling pressure, and cold pressing parameters. For finished product inspection, each batch of products is sampled and tested, including the bonding strength between the felt and the board, surface flatness, dimensional accuracy, and appearance quality. A complete quality traceability system has been established to ensure that each product can be traced back to its specific production batch and process parameters.

[0029] Example 1: Production of Standard Specification Felt Strips This embodiment details the complete process for producing standard felt strips with dimensions of 1.22 × 0.20 × 0.015 meters. First, suitable multi-layer plywood is prepared, with dimensions of 2.44 × 1.22 × 0.015 meters. The face veneer is made of high-quality birch veneer, and the core veneer is made of poplar veneer, pressed together using environmentally friendly urea-formaldehyde resin adhesive. The moisture content of the plywood is controlled between 8-12%, the density is 650-750 kg / m³, and the static bending strength is not less than 30 MPa. Simultaneously, industrial felt of the same size is prepared. The felt is made of a wool and chemical fiber blend material, with a density of 300-400 kg / m³, a thickness of 3 mm, and good elasticity and wear resistance.

[0030] At the start of production, the multi-layer boards are placed on the feeding platform of the automatic glue applicator. The automatic conveying system is activated, and the boards pass through the glue applicator station at a speed of 5 meters per minute. The nozzle assembly of the automatic glue applicator automatically adjusts the spraying range according to the width of the boards to ensure that the glue covers the entire surface of the boards. The amount of cold-pressed glue applied is controlled at 150-200 grams per square meter, and the uniformity of the glue thickness reaches over 95%. After glue application, the boards automatically enter the laying station. The mechanical tension arm system is activated, and six clamping points simultaneously clamp different positions of the felt sheet, precisely laying the felt onto the board surface through coordinated movements. During the laying process, the system monitors the positional deviation of the felt in real time and automatically adjusts the clamping force and movement trajectory to ensure that the laying accuracy is controlled within ±1 mm.

[0031] After the felt is laid, the felt sheets enter the rolling station, where eight sets of rotating columns sequentially roll the sheets. The pressure of the first set of rotating columns is set at 0.3 MPa, mainly for initial bonding; the pressure of the second to sixth sets of rotating columns gradually increases to 0.8 MPa to ensure full compaction; the pressure of the last two sets of rotating columns is reduced to 0.5 MPa for leveling. The entire rolling process takes about 30 seconds, resulting in a smooth surface on the rolled felt sheets, with a good initial bond formed between the felt and the sheets. The rolled sheets are automatically stacked, and when 90 sheets are accumulated, they are transferred by forklift to a cold press for curing.

[0032] During the cold-pressing curing stage, 90 sheets of felt are neatly placed on the worktable of the cold press. The hydraulic system is activated, and the pressure is gradually increased to 5 standard atmospheres. In the first 30 minutes of pressing, the pressure rises slowly to prevent excessive adhesive loss; then, a constant pressure is maintained for continuous pressing, with a total pressing time of 6 hours. During the pressing process, the cold-pressing adhesive fully cures under the combined action of pressure and time, forming a strong adhesive layer. After curing, the pressure is released and the felt sheets are removed. At this point, the felt and the sheet are completely bonded together, with a bonding strength exceeding 1.5 MPa.

[0033] Finally, an automated cutting process is performed, placing the cured large-sized felt-covered boards onto an electric saw cutting platform. According to product specifications, each 2.44×1.22 meter board needs to be cut into 12 strips, each 0.20 meter wide, along its length. The CNC system automatically positions the cutting line according to a preset program, and the high-speed electric saw cuts at a speed of 30 meters per minute. A dust removal system is included during the cutting process to promptly remove sawdust and felt fibers generated during cutting. After cutting, each strip measures 1.22×0.20×0.015 meters, with dimensional accuracy controlled within ±0.3 mm, and the cut surface is smooth and flat. The finished strips undergo quality inspection and are then packaged and stored, with 100 strips per package for easy transportation and use.

[0034] The production process described in this embodiment, from raw material preparation to finished product packaging, takes approximately 8 hours, with cold pressing and curing taking 6 hours. It can produce 240 preliminary felt boards per hour, equivalent to 2880 finished strips. The entire production line requires only 3 operators, increasing production efficiency by approximately 20 times compared to traditional manual methods. Labor costs have decreased from 2.5-3 yuan per strip to 0.3 yuan, significantly reducing production costs.

[0035] Example 2: Custom production of special specification thick strips This embodiment demonstrates the customized production process for special-specification felt strips with a thickness of 0.020 meters and a width of 0.15 meters. Due to the increased thickness of the board, some process parameters need to be adjusted to adapt to the new product requirements. In the raw material preparation stage, high-quality multi-layer plywood with a thickness of 0.020 meters is selected. This board uses a 13-layer veneer structure, which has higher mechanical strength and stability. Thickened industrial felt with a thickness of 4 mm is selected as the felt material, and the density is appropriately increased to 450 kg / m³ to provide better cushioning and protection.

[0036] In the automated gluing process, due to the increased thickness of the board, the glue application rate is adjusted to 180-220 grams per square meter to ensure sufficient glue penetration into the thickened felt. The gluing speed is appropriately reduced to 4 meters per minute, and the gluing time is extended to ensure thorough and uniform gluing. The mechanical tension hand system adjusts the clamping force parameters for the thickened felt, increasing the clamping force at the clamping points to cope with the increased weight of the felt, while optimizing the movement trajectory to adapt to the surface characteristics of the thicker board.

[0037] During the rolling process, the rolling parameters were adjusted to suit the characteristics of the thicker strips, increasing the maximum rolling pressure to 1.2 MPa and extending the rolling time to 45 seconds to ensure that the thickened felt could fully adhere to the board. Especially in the first three sets of rotating columns, a progressive pressure method was used to avoid excessive pressure that could cause felt deformation or excessive extrusion of the adhesive. In the cold-pressing and curing stage, due to the increased board thickness, only 60 sheets could be processed per batch. The cold-pressing pressure was increased to 6 atmospheres, and the pressing time was extended to 8 hours to ensure that the thicker boards could be completely cured.

[0038] In the automated cutting process, each sheet of board needs to be cut into eight strips, each 0.15 meters wide, according to specific specifications. Due to the increased thickness of the board, a precision saw blade with more teeth is selected, reducing the cutting speed to 25 meters per minute to ensure cutting quality. The finished strips after cutting measure 1.22 × 0.15 × 0.020 meters, offering higher mechanical strength and better protective performance, making them particularly suitable for pallet applications for heavy-duty ceramic products.

[0039] Example 3: High-efficiency continuous production mode This embodiment describes a process scheme for achieving efficient mass production using a multi-line parallel and continuous production mode. This mode is suitable for the production needs of large orders and standardized products, and can fully leverage the capacity advantages of automated equipment. The production line configuration includes two parallel glue application and laying lines, three cold presses, and two cutting lines, forming a complete continuous production system.

[0040] In continuous production mode, two adhesive application and laying lines operate simultaneously, each processing 240 sheets per hour, for a total of 480 sheets per hour. To match the processing capacity of the cold presses, an intermediate buffer system is established, capable of temporarily storing 360 preliminary felt-covered sheets. The three cold presses operate in a staggered start-up mode: the first cold press is loaded and started pressing immediately after production begins, the second cold press starts after 2 hours, and the third cold press starts after 4 hours, forming a continuous curing cycle of one batch every 2 hours.

[0041] In this production model, each complete production cycle lasts 6 hours, producing 2,160 sheets of felt-covered boards, equivalent to 25,920 standard-sized strips. The two cutting lines operate alternately to ensure timely processing of cured boards. The entire continuous production model can produce 8,640 sheets of felt-covered boards per day, equivalent to 103,680 finished strips, achieving a production efficiency more than 50 times that of traditional manual methods.

[0042] Through precise production planning and equipment coordination, the continuous production mode not only significantly improves production efficiency but also substantially reduces the production cost per unit product. Equipment utilization reaches over 95%, and energy consumption is controlled to within 0.08 kWh per strip, achieving the goal of high-efficiency, energy-saving, and green production. This production mode is particularly suitable for providing mass-produced felt strip products to large-scale ceramic manufacturers, effectively supporting the automation transformation and upgrading needs of the ceramic industry.
