Description

Technical Field

[0001] This invention relates to the field of textile material processing equipment technology, specifically a device for precise dynamic coating of adhesives on the surface of textile substrates. Background Technology

[0002] The device for precise dynamic coating of adhesive on textile substrates is a specialized piece of equipment designed specifically for the textile industry. Its core function is to achieve precise coating of adhesive on the surface of the substrate through a specific mechanical structure and control system while the textile substrate is in a continuous dynamic transmission state.

[0003] Existing technology, such as the surface coating device for textile fabric processing disclosed in patent number CN111495676B, includes a working machine housing with a coating rack inside. The coating rack is installed inside the working machine housing via a transmission roller. Several coating supports are installed at equal angles on the outer roller surface of the transmission roller. A material box and a material conveying cylinder are installed on the material conveying frame. The conveying end of the material box is connected to the material conveying cylinder via a feeding conduit. The conveying end of the material conveying cylinder extends into the inner cavity of the working machine housing via a feeding conduit. The bottom end of the feeding conduit is located directly above the coating rack. A piston plate is provided in the inner cavity of the material conveying cylinder. A crank transmission rod is installed at the rear end of the material conveying cylinder, and a piston rod is installed at the bent end of the crank transmission rod. This application can ensure that the coating is effectively coated on the fabric, preventing the problem of dry coating. At the same time, the material is coated in equal amounts at each interval, making the coating more uniform.

[0004] Existing technologies for coating adhesives on textile substrates have several shortcomings. For example, during dynamic coating, it is difficult to accurately adjust the height and position of the coating structure in real time according to parameters such as the thickness and width of different textile substrates, resulting in uneven adhesive coating thickness and affecting product quality. The fixed movement trajectory of the spraying components in the device cannot adapt to substrates of different widths, easily leading to missed coating or adhesive waste. The adjustment accuracy of key components such as the scraper roller and drive roller in the device is low, and the adjustment process is complex, making it difficult to meet the needs of high-precision production. Frequent machine stops are required for adjustments during mass production, reducing production efficiency. Therefore, we propose a device for precise dynamic coating of adhesives on textile substrates. Summary of the Invention

[0005] One of the technical problems this application aims to solve is that existing devices cannot accurately adjust the height and position of the coating structure in real time according to parameters such as the thickness and width of different textile substrates. The fixed movement trajectory of the spraying components of the device cannot adapt to substrates of different widths, which can easily lead to missed coating or waste of adhesive, resulting in uneven coating thickness and affecting product quality.

[0007] Preferably, the circulating spraying component includes a guide frame disposed on the upper part of the lifting platform, a slider slidably connected inside the guide frame, a spray head disposed at the front of the slider, a timing belt disposed inside the slider, and a scraper disposed at the lower part of the lifting platform.

[0008] Preferably, the lifting component one includes a high-precision electric push rod one disposed in the middle of the mounting frame two. The upper end of the high-precision electric push rod one is disposed in the lower part of the lifting platform. Slide rods are slidably connected to the left and right sides inside the mounting frame two. The upper and lower ends of the slide rods are respectively disposed in the upper part of the lifting component two and the lower part of the lifting platform.

[0009] Preferably, the second lifting component includes a mounting plate disposed on the upper part of the frame. The mounting plate has a plurality of evenly distributed lifting blocks inside. The lower ends of two adjacent lifting blocks are respectively provided with scraper rollers and drive rollers. The upper part of the mounting plate is slidably connected to a plurality of evenly distributed push plates, and the upper side of the push plates is slidably connected to the right side of the lifting blocks.

[0010] Preferably, two symmetrically distributed servo motors are provided at the upper edge of the lifting platform, and a synchronous pulley is provided at the drive end of the servo motor. The synchronous belt is sleeved on the outer periphery of the two synchronous pulleys, and a counterweight is provided at the rear end of the slider.

[0011] Preferably, the upper part of the mounting plate is rotatably connected to two screws, and two adjacent push plates are respectively threaded to the left end and the middle outer periphery of the screws. A speed reduction drive is provided at the right end of the screws, and the two micrometers are respectively located on the right side of the scraper roller and the drive roller.

[0012] Preferably, one of the micrometers is located on the right side of the lifting platform, and multiple reference platforms are respectively located on the upper right side of the mounting frame two and the right side of the frame. The lower end of the micrometer abuts against the upper part of the reference platform, and the lower part of the mounting frame one is provided with a positioning element for identifying the carpet width and limiting the carpet position.

[0013] Preferably, the positioning component includes two symmetrically distributed high-precision electric actuators, namely, high-precision electric actuator II and high-precision electric actuator III, disposed at the lower part of the mounting frame I. Two symmetrically distributed fixed frames are disposed at the lower part of the mounting frame I. A sensor and a limiting plate are slidably connected in the middle of the fixed frames. The ends of high-precision electric actuator II and high-precision electric actuator III near the fixed frames are respectively disposed on the outer walls of the sensor and the limiting plate. A limiting block is disposed at the front of the sensor.

[0014] Preferably, a fixed block is provided on the upper part of the lifting platform, and a second synchronous pulley is rotatably connected to the upper part of the fixed block. The second synchronous pulley meshes with the middle part of the synchronous belt.

The drive roller also has its height independently adjustable (displacement displayed by a micrometer), and it conveys and pulls the substrate after scraping, facilitating its entry into the next process.

[0020] 5. The micrometer, in conjunction with the reference platform, displays real-time displacement data at key positions of the lifting platform, scraper roller, and drive roller, providing operators with intuitive parameter adjustment guidelines and ensuring the accuracy of each structural position.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-5The present invention provides a technical solution: a device for precise dynamic scraping of adhesive on the surface of textile substrate, comprising a frame 1, a mounting frame one 11, a mounting frame two 12, a lifting platform 13, multiple micrometers 14 and multiple reference platforms 15. The mounting frame one 11 and the mounting frame two 12 are both arranged on the upper part of the frame 1. The lifting platform 13 is slidably connected to the upper part of the mounting frame two 12. The upper part of the frame 1 is provided with a lifting component two 4 for adjusting the application and leveling of adhesive. The middle part of the mounting frame two 12 is provided with a lifting component one 3 for driving the lifting component two 4 and the lifting platform 13 to move. The upper part of the lifting platform 13 is provided with a circulating spraying component 2 for circulating adhesive spraying.

[0025] The frame 1 integrates multiple rotatable guide wheels to assist the movement of the blanket on the upper part of the frame 1. Mounting frame 11 and mounting frame 2 12 are the mounting structures for positioning component 5 and lifting platform 13, respectively, providing stable structural support. The circulating spraying component 2 uses a drive structure to stably and cyclically spray adhesive onto the blanket, preventing uneven adhesive spraying. Lifting component 1 3 uses mounting frame 2 12 as a fulcrum and can simultaneously push lifting platform 13 and lifting component 2 4 to move, realizing basic height adjustment. The micrometer 14 is existing technology and can identify its displacement data relative to the reference platform 15, which is then displayed on the dial. The reference platform 15 is a positioning reference surface installed at a fixed position on the surface of the device, which can provide reference surface support for the displacement of the micrometer 14 and realize displacement data reading. Furthermore, the circulating spraying component 2 includes a guide frame 25 disposed on the upper part of the lifting platform 13, a slider 23 slidably connected inside the guide frame 25, a spray head 24 disposed at the front of the slider 23, a timing belt 22 disposed inside the slider 23, and a scraper 28 disposed at the lower part of the lifting platform 13.

[0026] Two symmetrically distributed servo motors 21 are provided at the upper edge of the lifting platform 13. The drive end of the servo motor 21 is provided with a synchronous pulley 27. The synchronous belt 22 is sleeved on the outer periphery of the two synchronous pulleys 27. The rear end of the slider 23 is provided with a counterweight 26.

[0027] The guide frame 25 is fixed to the upper part of the lifting platform 13. The slider 23 slides in the middle slot to provide support for the sliding of the nozzle 24. The synchronous belt 22, servo motor 21 and synchronous pulley 27 work together to adjust the rotation of the two servo motors 21 in real time according to the carpet width data collected by the sensor 54, thereby driving the synchronous belt 22 to rotate periodically. Then, the slider 23 drives the nozzle 24 to slide periodically above the carpet in the direction of carpet movement. The upper part of the nozzle 24 can be connected to a pipe for supplying glue, and the nozzle at the lower part can spray glue evenly, thereby realizing the reciprocating spraying of the nozzle 24. The scraper 28 is a structure for flattening glue fixed to the lower part of the lifting platform 13. The lower part of the part in contact with the glue has evenly distributed grids. The raised part can prevent the glue from shifting when flattening it, and can limit the glue from shifting in the direction of carpet movement to a certain extent, so as not to cause the glue to flow out of the carpet. Furthermore, the lifting component 3 includes a high-precision electric push rod 31 disposed in the middle of the mounting frame 2 12. The upper end of the high-precision electric push rod 31 is disposed in the lower part of the lifting platform 13. Slide rods 32 are slidably connected to the left and right sides inside the mounting frame 2 12. The upper and lower ends of the slide rods 32 are respectively disposed in the upper part of the lifting component 2 4 and the lower part of the lifting platform 13.

[0028] The high-precision electric actuator 31 uses the middle of the mounting bracket 12 as a fulcrum, and its upper part can directly push the lifting platform 13 to move up and down. Through the connection of two sliding rods 32, the lifting platform 13, sliding rods 32 and mounting plate 41 can be connected to form a structure that can slide synchronously. When the high-precision electric actuator 31 is started, it can drive the three to move synchronously. According to the parameters of the blanket input device, the high-precision electric actuator 31 can push the assembly to the first position, so that the nozzle 24 and scraper 28 are in the best position for spraying and blocking glue. The lifting component 4 is also pushed to the basic height, thereby realizing the height adjustment of the nozzle 24 and scraper 28 and the basic height position adjustment of the lifting component 4. Furthermore, the lifting component 4 includes a mounting plate 41 disposed on the upper part of the frame 1. The mounting plate 41 has a plurality of evenly distributed lifting blocks 42 disposed inside. The lower ends of two adjacent lifting blocks 42 are respectively provided with scraper rollers 45 and drive rollers 46. The upper part of the mounting plate 41 is slidably connected to a plurality of evenly distributed push plates 43, and the upper side of the push plates 43 is slidably connected to the right side of the lifting blocks 42.

[0029] The upper part of the mounting plate 41 is rotatably connected to two screws 44. Two adjacent push plates 43 are threadedly connected to the left end and the middle outer periphery of the screws 44, respectively. The right end of the screws 44 is provided with a speed reduction drive motor. Two micrometers 14 are respectively located on the right side of the scraper roller 45 and the drive roller 46.

[0030] Mounting plate 41 serves as the upper structural platform, with two sliding rods 32 directly fixed to it for moving the lifting component 4 as a whole. Similarly, based on the parameters input by the device and the parameters for the high-precision electric push rod 31 to move the lifting component 4, the two reduction drive motors on the right side of mounting plate 41 can rotate and drive the scraper roller 45 and drive roller 46 according to the program set by the device, changing the height of the scraper roller 45 and drive roller 46 relative to the frame 1. The reduction drive motors can drive the screw 44 to rotate, and the screw 44 pushes the push plate 43 to move through its surface spiral structure. The contact surface between the push plate 43 and the lifting block 42 is T-shaped, so the push plate 43 can both push the lifting block 42 upward and pull the lifting block 42 downward using the T-shaped structure, thereby pushing the scraper roller 45 and drive roller 42. The lifting mechanism 46 is controlled independently by two separate reduction drive motors. These two motors are not interconnected and can be adjusted independently. This allows for independent adjustment of the lifting height of the scraper roller 45 and the drive roller 46. The scraper roller 45 is made of high-quality material and its surface is specially treated to prevent glue from adhering to its surface. The gap between the scraper roller 45 and the frame 1 is adjusted by the first reduction drive motor to achieve different coating thicknesses for different substrates and process requirements. A micrometer 14 is equipped on its right side, which can cooperate with the reference platform 15 to display the current displacement information. The rotation of the scraper roller 45 is adjusted with high precision by the second reduction drive motor on its right side to enable continuous production of batch products. The coated blanket is transported by the drive roller 46 to facilitate the next process. The gap of the drive roller 46 is adjusted by the second reduction drive motor, and its displacement data is displayed by the micrometer 14. Furthermore, one of the micrometers 14 is located on the right side of the lifting platform 13, and multiple reference platforms 15 are respectively located on the upper right side of the mounting frame 12 and the right side of the frame 1. The lower end of the micrometer 14 abuts against the upper part of the reference platform 15, and the lower part of the mounting frame 11 is provided with a positioning element 5 for identifying the carpet width and limiting the carpet position.

[0031] The positioning component 5 includes two symmetrically distributed high-precision electric actuators 51 and 52 located at the lower part of the mounting bracket 11. The lower part of the mounting bracket 11 is provided with two symmetrically distributed fixing brackets 53. The middle part of the fixing bracket 53 is slidably connected to a sensor 54 and a limiting plate 55. The ends of the high-precision electric actuators 51 and 52 near the fixing brackets 53 are respectively located on the outer walls of the sensor 54 and the limiting plate 55. The front part of the sensor 54 is provided with a limiting block 56.

[0032] The micrometer 14 and the reference platform 15 are distributed at the key displacement positions of the device. The displacement information at the corresponding position can be read through the micrometer 14, providing real data support for users to judge the adjustment of device parameters.

[0033] The two high-precision electric actuators 51 and 52 operate independently without interference. Sensor 54 is a prior art device that can identify the thickness and width of the blanket. Sensor 54 and limit plate 55 slide in the middle of the fixed frame 53 without interference. High-precision electric actuator 51 is activated when the device is running. High-precision electric actuator 51 drives sensor 54 and limit block 56 to move in the direction perpendicular to the blanket. When sensor 54 detects a change in distance, it records the displacement and the distance it moves, and then transmits it to the device control device for subsequent height parameter adjustment. Limit block 56 can position the blanket when sensor 54 stops. Then, high-precision electric actuator 52 pushes limit plate 55 to move closer to the blanket according to the data returned by the control device. The two limit plates 55 can clamp the blanket inside, thereby restricting the blanket and preventing it from shifting. Example 2: Please refer to Figure 6 and Figure 7 The present invention provides a technical solution: a fixed block 281 is provided on the upper part of the lifting platform 13, and a synchronous pulley 282 is rotatably connected to the upper part of the fixed block 281. The synchronous pulley 282 meshes with the middle part of the synchronous belt 22. A connecting rod 283 is provided at the front end of the synchronous pulley 282. A connecting rod 284 is rotatably connected to the end of the connecting rod 283 away from the synchronous pulley 282. The lower end of the connecting rod 284 is rotatably connected to the upper part of the scraper 28.

[0034] The lower part of the lifting platform 13 is provided with a guide block 285, and two symmetrically distributed rollers 286 are slidably connected inside the guide block 285. The rollers 286 are located on the upper rear side of the scraper 28.

[0035] Synchronous pulley 282 can be matched with synchronous belt 22. The driven structure composed of fixed block 281 and synchronous pulley 282 can wrap the lower part of synchronous belt 22 inside it to prevent synchronous belt 22 from separating from the two. When synchronous belt 22 rotates, it can drive connecting rod 283 to rotate. Connecting rod 283 pushes connecting rod 284 to move periodically. Connecting rod 284 will rotate slightly to adapt to the rotation of connecting rod 283. When connecting rod 284 moves left and right periodically, it will push scraper 28 to slide slightly left and right. Scraper 28 can push glue to move, so that the glue is evenly spread on the surface of the blanket. Guide block 285 is a hollow guide structure in the middle. Roller 286 can slide inside it without obstruction. Roller 286 can provide support for scraper 28 when it moves. Thus, when the nozzle 24 sprays glue, scraper 28 can slide slightly to spread the glue evenly.

[0036] Although embodiments of the 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 invention.
