Description

Technical Field

[0001] This utility model relates to the field of foam material production technology, specifically a feeding device for the continuous production of melamine foam material. Background Technology

[0002] In the continuous production process of melamine foam materials, the fabric supply device is a key piece of equipment, and its performance directly affects the quality of the final product and production efficiency. The fabric supply device is mainly responsible for continuously and stably conveying the fabric to the production line at a predetermined speed and tension, providing basic material support for subsequent foaming, molding and other processes.

[0003] However, existing fabric feeding devices for continuous production of melamine foam materials have significant drawbacks. Most existing devices focus solely on fabric conveying, lacking a mechanism for effectively detecting fabric integrity. In actual production scenarios, fabric may develop holes or damage during storage, transportation, or early processing for various reasons. When these defective fabrics are fed onto the production line, it leads to a series of serious consequences. On the one hand, fabrics with holes cannot fully bond with melamine foam materials in subsequent processes, resulting in uneven density and loose structure in the foam material during molding, reducing the overall performance and quality stability of the product. On the other hand, if the produced melamine foam materials have quality defects, it not only wastes raw materials but also requires additional manpower and resources for defective product processing, significantly increasing production costs, affecting production cycles, and reducing the company's market competitiveness.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4This utility model provides a technical solution: a fabric feeding device for continuous production of melamine foam material, including a fabric frame 1, a conveying roller 3 rotatably mounted on the fabric frame 1, a drive motor 7 for driving the conveying roller 3 to rotate on the fabric frame 1, a fabric body 6 wound on the conveying roller 3, an upper guide roller 4 and a lower guide roller 5 rotatably mounted on the fabric frame 1, a channel for the fabric body 6 to pass through is formed between the upper guide roller 4 and the lower guide roller 5, the fabric body 6 is conveyed to the outside through the channel, and a detection mechanism for detecting the fabric body 6 is also provided on the fabric frame 1, the detection mechanism including a mounting shell 16 mounted on the fabric frame 1, the mounting shell 16 extending along the width direction of the fabric body 6, an inlet and an outlet for the fabric body 6 to pass through and exit respectively on the left and right side walls of the fabric body 6, a positive electrode plate 18 and a negative electrode plate 19 are mounted inside the mounting shell 16 through an insulating seat 17, the positive electrode plate 18 and the negative electrode plate 19 respectively correspond to the upper and lower surfaces of the fabric body 6.

[0023] Specifically, the drive motor 7 rotates, driving the conveyor roller 3 to rotate. The fabric body 6, wound on the conveyor roller 3, begins to be conveyed. The fabric body 6 passes through the channel formed by the upper guide roller 4 and the lower guide roller 5, achieving stable guided conveying. The mounting shell 16 of the detection mechanism extends along the width direction of the fabric body 6. The fabric body 6 enters from the inlet and exits from the outlet. The positive electrode plate 18 and the negative electrode plate 19 inside the mounting shell 16 correspond to the upper and lower surfaces of the fabric body 6, respectively. When the fabric body 6 is intact, the resistance between the positive electrode plate 18 and the negative electrode plate 19 is in a normal state. If the fabric body 6 has holes or other damage, the resistance between the positive electrode plate 18 and the negative electrode plate 19 will change at the damaged area, thereby realizing the detection of the integrity of the fabric. By setting the drive motor 7 and the conveyor roller 3, the automatic continuous conveying of the fabric body 6 can be realized, improving production efficiency. The channel formed by the upper guide roller 4 and the lower guide roller 5 can stably guide the fabric and prevent the fabric from deviating. The establishment of the testing agency effectively solves the problem that existing fabric supply devices in the background technology cannot detect the integrity of the fabric. By detecting changes in the fabric's resistance, it can determine whether the fabric is damaged. Problems can be detected in time before the fabric enters the subsequent production stage, avoiding quality problems of melamine foam material due to fabric defects, ensuring product quality, and reducing raw material waste and defective product handling costs.

[0024] As a technical optimization of this utility model, an electrical cabinet 9 is installed on the side wall of the fabric rack 1, and the drive motor 7, the positive electrode plate 18 and the negative electrode plate 19 are all electrically connected to the electrical cabinet 9.

[0025] Specifically, the electrical cabinet 9 enables centralized control of the drive motor 7 and the detection mechanism, making the entire fabric supply device more intelligent and automated. It can adjust the equipment's operating status promptly based on the detection results, further improving the stability and reliability of the production process and ensuring continuous and efficient production.

[0026] As a technical optimization of this utility model, it also includes an emergency stop assembly set on the fabric frame 1. The emergency stop assembly includes a rotating shaft 10 rotatably mounted on the fabric frame 1. Both ends of the rotating shaft 10 are connected to a swing plate 11. The top of the swing plate 11 is provided with a mounting groove 12. A brake roller 13 is installed in the mounting groove 12. A rubber block 8 is provided on the outer wall of the brake roller 13. A cylinder 14 is hinged to the fabric frame 1. The telescopic end of the cylinder 14 is hinged to the swing plate 11.

[0027] Specifically, when the inspection agency detects damage to the fabric body 6, the cylinder 14 is activated. The telescopic end of the cylinder 14 pushes the swing plate 11 to rotate around the shaft 10. The brake roller 13, installed in the mounting groove 12 at the top of the swing plate 11, swings accordingly. The rubber block 8 on the outer wall of the brake roller 13 contacts the fabric body 6 and applies pressure, thereby braking the fabric body 6 and stopping the fabric conveying. The emergency stop component can quickly stop the fabric conveying when the fabric is damaged, preventing defective fabric from continuing to enter subsequent production stages, preventing more defective products from being produced due to fabric problems, and reducing raw material waste and economic losses. At the same time, the rubber block 8 can effectively protect the fabric during braking, avoiding additional damage to the fabric.

[0028] As a technical optimization of this utility model, two sets of upper guide rollers 4 and lower guide rollers 5 are provided, and the detection mechanism is set between the two sets of upper guide rollers 4 and lower guide rollers 5.

[0029] Specifically, the arrangement of two sets of upper guide rollers 4 and lower guide rollers 5 improves the stability of the fabric conveying process and prevents the fabric from shifting or wrinkling during conveying, thereby ensuring that the detection mechanism can accurately detect the integrity of the fabric.

[0030] As a technical optimization of this utility model, a driven sprocket is provided on the shaft end of the conveying roller 3, and a driving sprocket is provided on the driving end of the drive motor 7. A chain is used to drive the driving sprocket and the driven sprocket.

[0031] Specifically, the use of sprocket and chain drive has advantages such as high transmission efficiency, accurate transmission ratio, and compact structure, which can ensure the stable and reliable rotation of the conveying roller 3, thereby realizing the stable and continuous conveying of the fabric body 6.

[0032] As a technical optimization of this utility model, a tension roller 15 is rotatably installed on the fabric frame 1, and the tension roller 15 presses against the surface of the fabric body 6.

[0033] Specifically, the tension roller 15 can effectively prevent the fabric from becoming loose or piling up during the conveying process, ensuring that the fabric is conveyed with appropriate tension.

[0034] As a technical optimization of this utility model, the fabric frame 1 is also equipped with reinforcing beams 2, and multiple reinforcing beams 2 are provided.

[0035] Specifically, the reinforcement beam 2 improves the structural strength and stability of the fabric frame 1, effectively bearing various loads during equipment operation and extending the service life of the fabric supply device.

[0036] Working Principle: The drive motor 7 drives the conveyor roller 3 to rotate via a sprocket and chain drive, conveying the fabric body 6 wound on the conveyor roller 3. During the conveying process, the fabric body 6 first passes through a channel composed of two sets of upper guide rollers 4 and lower guide rollers 5. These two sets of guide rollers play a stabilizing and guiding role, keeping the fabric in a stable conveying state. Subsequently, the fabric enters the mounting shell 16 of the detection mechanism. The positive electrode plate 18 and negative electrode plate 19 inside the mounting shell 16 correspond to the upper and lower surfaces of the fabric body 6. By detecting the change in the fabric resistance, it is determined whether the fabric is damaged. If the fabric is intact, the resistance between the positive and negative electrode plates is in a normal state; if the fabric has holes or other damage, the resistance at the damaged area will change, and the detection signal is transmitted to the electrical cabinet 9. When the electrical cabinet 9 receives the fabric damage signal, it starts the control cylinder 14. The cylinder 14 pushes the swing plate 11 to rotate around the rotating shaft 10, so that the rubber block 8 on the brake roller 13 contacts the fabric and brakes it, stopping the fabric conveying. Meanwhile, the tension roller 15 always presses the fabric body 6 to maintain the tension of the fabric during the conveying process, while multiple reinforcing beams 2 provide structural support for the fabric frame 1 to ensure the stable operation of the entire device.
