Description

Technical Field

[0001] This application relates to the technical field of composite adsorbent material production equipment, and in particular to an automatic adhesive coating device for composite adsorbent materials. Background Technology

[0002] Composite adsorbent materials are a new type of functional material composed of multiple adsorbent components through specific processes. Due to their superior properties such as large specific surface area, high adsorption capacity, and strong selectivity, they show great application potential in fields such as environmental protection, medical and health care, and industrial separation and purification. These materials are typically manufactured in roll form using flexible sheet-like matrix materials for support, facilitating large-scale continuous production, transportation, and practical application.

[0003] In its production process, adhesive coating is a key step, used to fix adsorbed components, construct multilayer structures, or impart surface properties. Currently, roller coating technology is commonly used, where a coating roller is partially immersed in an adhesive tank, and the adhesive is transferred to the surface of the sheet-like substrate by rotation. However, this method has significant drawbacks: initially, the adhesive is plentiful, the liquid level is high, the immersion area of ​​the coating roller is large, and the amount of adhesive adhered per unit time is high; as production progresses, the adhesive is continuously consumed, the liquid level gradually decreases, leading to a reduction in the immersion area of ​​the roller and a corresponding decrease in the amount of adhesive adhered. This instability in adhesive transfer directly causes a decrease in coating uniformity, manifested as inconsistent adhesive coverage per unit area in different sections of the sheet-like substrate. This, in turn, leads to uneven distribution of adsorbed components, fluctuations in interlayer bonding strength, and inconsistent final product performance, severely affecting product quality stability and batch-to-batch repeatability. Utility Model Content

[0004] To address the problem of uneven coating caused by adhesive consumption during the production of composite adsorbent materials, this application provides an automatic adhesive coating device for composite adsorbent materials.

[0005] The automatic coating device for composite adsorbent materials provided in this application adopts the following technical solution: An automatic coating device for composite adsorbent materials includes a coating assembly and a support frame. The coating assembly includes a glue storage box, a coating roller, a pressing roller, and a leveling roller. The glue storage box is mounted on the support frame, and the coating roller is mounted on the support frame, with a portion of the coating roller located inside the glue storage box. The leveling roller is mounted on the support frame, located to one side of the coating roller, with a portion of the leveling roller located inside the glue storage box. The leveling roller is also in contact with the coating roller. The pressing roller is located above the coating roller and is used to press the sheet-like substrate onto the coating roller.

[0006] By adopting the above technical solution, the specific arrangement of the leveling roller and the coating roller allows the leveling roller to be partially immersed in the glue storage box and kept in contact with the surface of the coating roller. This structure enables the leveling roller to squeeze and remove excess glue from the surface of the coating roller when there is a large amount of glue, and to replenish the glue to the coating roller with its own immersed portion when the glue level drops due to consumption. This automatically compensates for the changes in the liquid level caused by glue consumption during the production process, effectively maintaining a uniform thickness of the glue film adhering to the surface of the coating roller, thereby improving the uniformity of glue coating on sheet substrates.

[0007] Preferably, the support frame is provided with a glue tank, which is located above the glue storage box. A glue discharge pipe is provided at the lower end of the glue tank, with the port of the glue discharge pipe facing the glue storage box. A valve is provided on the glue discharge pipe.

[0008] By adopting the above technical solution, a glue replenishment system is constructed by setting up a glue tank above the glue storage box and a glue supply pipe with a valve connected to its lower end. This system can adjust the rate at which glue is replenished into the glue storage box by controlling the opening and closing of the valve as needed, helping to maintain a relatively stable glue level in the storage box and providing a stable glue-impregnating environment for the coating roller.

[0009] Preferably, the support frame is further provided with a lifting cylinder, which is vertically arranged below the glue storage box, and the end of the piston rod of the lifting cylinder is arranged on the bottom wall of the glue storage box.

[0010] By adopting the above technical solution, a lifting cylinder is installed below the glue storage box, and the piston rod end is connected to the bottom wall of the glue storage box, realizing the overall lifting function of the glue storage box. This structure facilitates the lowering of the glue storage box and its separation from the coating roller and leveling roller when maintenance is required, providing ample operating space for cleaning the roller surface, replacing the glue, or performing equipment maintenance, thereby improving the maintainability and ease of operation of the equipment.

[0011] Preferably, the support frame is further provided with a first sliding groove, and the end of the glue-spreading roller is provided with a first support block, which is disposed in the first sliding groove; the support frame is further provided with an adjustment assembly, which includes an adjustment screw, which is disposed on the support frame and is also threadedly connected to the first support block; the adjustment screw is used to adjust the tightness between the glue-spreading roller and the glue-coating roller.

[0012] By adopting the above technical solution, an adjusting screw threadedly connected to the first support block at the end of the coating roller is provided. This allows the operator to precisely drive the first support block and the coating roller on it by rotating the adjusting screw, thereby fine-tuning the radial clamping force between the coating roller and the glue-applying roller. This mechanical adjustment method can precisely control the gap or pressure between the two rollers, thus achieving fine control over the thickness of the glue film coated on the surface of the glue-applying roller.

[0013] Preferably, the support frame is provided with a first guide rod, the first guide rod is slidably engaged with the first support block, and a first spring is sleeved on the first guide rod, one end of the first spring abutting against the support frame and the other end of the first spring abutting against the first support block.

[0014] By adopting the above technical solution, this solution provides stable guidance and continuous preload for the adjustment system through the setting of a first guide rod that slides in cooperation with the first support block, and a first spring sleeved on the first guide rod and acting on the first support block. The elastic force of the first spring ensures that the thread inside the first support block and the external thread of the adjusting screw always maintain close contact, enhancing the self-locking performance of the threaded pair, preventing the screw from accidentally loosening during equipment operation vibration, and ensuring the long-term stability of the clamping force between the glue-spreading roller and the glue-applying roller.

[0015] Preferably, the support frame has a second sliding groove, and the end of the coating roller is provided with a second support block, which is disposed in the second sliding groove; the end of the pressing roller is provided with a third support block, which is disposed in the second sliding groove and is also located above the second support block; the adjustment assembly further includes an adjustment cylinder, which is vertically disposed on the support frame, and the end of the piston rod of the adjustment cylinder is disposed on the third support block; the adjustment cylinder is used to adjust the distance between the pressing roller and the coating roller.

[0016] By adopting the above technical solution, which involves setting up an adjusting cylinder and connecting the piston rod end to a third support block supporting the pressing roller, the pressing roller is pneumatically driven to move up and down relative to the coating roller. This allows the device to quickly adjust the gap between the pressing roller and the coating roller to accommodate sheet substrate materials of different thicknesses, expanding the processing range and application flexibility of the equipment.

[0017] Preferably, a second guide rod is vertically provided on the second support block, the second guide rod is slidably engaged with the third support block, a second spring is sleeved on the second guide rod, one end of the second spring abuts against the third support block, and the other end of the second spring abuts against the second support block.

[0018] By adopting the above technical solution, this solution constructs an elastic support system by setting a vertical second guide rod on the second support block supporting the coating roller, and slidingly engaging the third support block supporting the pressing roller with the second guide rod. Simultaneously, a second spring is installed on the second guide rod, with its two ends acting on the second and third support blocks respectively. The elastic force of the second spring can offset part of the self-weight of the pressing roller and its supporting components, thereby significantly reducing the supporting force required by the adjusting cylinder when lifting and maintaining the position of the pressing roller, reducing the cylinder load, and helping to improve the cylinder's service life and position control stability.

[0019] Preferably, a feeding assembly is provided on one side of the adhesive coating assembly. The feeding assembly includes a feeding guide roller, a feeding roller, and a feeding motor. The feeding guide roller, the feeding roller, and the feeding motor are all mounted on the support frame. The feeding roller is located on one side of the feeding guide roller. The feeding guide roller is used to guide the sheet substrate into the support frame. The feeding motor is used to drive the feeding roller to rotate. The feeding roller is used to convey the sheet substrate into the support frame.

[0020] By adopting the above technical solution, this solution achieves the guidance, conveying, and lateral positioning of the sheet substrate by setting a feeding component on one side of the coating assembly. This component includes a feeding guide roller, a feeding roller, and a feeding motor that drives the feeding roller. Specifically, a limiting plate is installed on the feeding guide roller. The limiting plate effectively prevents the sheet substrate from deviating, tilting, or wrinkling before entering the coating area, ensuring that the sheet substrate enters between the coating roller and the pressure roller in a flat and accurate position. This provides a prerequisite for ensuring the accuracy of the coating position and the stability of the coating quality.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Through a specific arrangement of the leveling roller and the coating roller, the leveling roller is partially immersed in the glue storage box and kept in contact with the surface of the coating roller. This structure allows the leveling roller to squeeze and remove excess glue from the surface of the coating roller when there is a large amount of glue, and to replenish the glue to the coating roller with its own immersed portion when the glue level drops due to consumption. This automatically compensates for the changes in the liquid level caused by glue consumption during production, effectively maintaining a uniform thickness of the glue film adhering to the surface of the coating roller, thereby improving the uniformity of glue coating on sheet substrates.

[0022] 2. By adjusting the screw mechanism settings, the pressure between the coating roller and the glue-applying roller can be precisely controlled to ensure the uniformity of the glue film thickness.

[0023] 3. By adjusting the setting of the cylinder-driven pressing roller, the device can adapt to sheet substrates of different thicknesses.

[0024] 4. The upper limit plate of the feed guide roller ensures the stability and centering of the sheet substrate during the conveying process. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses an automatic coating device for composite adsorbent materials, referring to... Figure 1 The system includes an adhesive coating assembly 3 and a support frame 1. The adhesive coating assembly 3 is mounted on the support frame 1, and a feeding assembly 2 is mounted on the support frame 1. The feeding assembly 2 is located on one side of the adhesive coating assembly 3. The feeding assembly 2 is used to introduce the sheet substrate 5 from the previous process into the support frame 1, and the adhesive coating assembly 3 is used to apply adhesive to the sheet substrate 5.

[0032] Reference Figures 1-2The feeding assembly 2 includes a feeding guide roller 21, a feeding roller 22, a feeding motor 23, and a tension roller 24. The feeding guide roller 21, feeding roller 22, and tension roller 24 are all rotatably connected to the support frame 1. The feeding guide roller 21 is used to guide the sheet substrate 5 into the support frame 1. The feeding guide roller 21 has two limiting plates 211 along its own axis. The limiting plates 211 are mainly used to laterally limit and guide the sheet substrate 5, preventing it from shifting, tilting, or wrinkling before entering the coating area, thereby ensuring stable transmission of the sheet substrate 5, accurate coating position, and improving coating uniformity and product quality. The feeding roller 22 is located on one side of the feeding guide roller 21. The feeding motor 23 is fixedly connected to the side wall of the support frame 1, and the feeding motor 23 drives the feeding roller 22 to rotate, thus conveying the sheet substrate 5 into the support frame 1.

[0033] Reference Figures 1-2 After being introduced by the feed guide roller 21, the sheet-like substrate 5 passes successively along the conveying path through the feed roller 22 and the tension roller 24. Specifically, the sheet-like substrate 5 first wraps around and adheres tightly to a portion of the feed roller 22, and then turns to wrap around and adhere tightly to a portion of the tension roller 24. The feed roller 22 and the tension roller 24 are arranged vertically in space. The sheet-like substrate 5 passes over the lower roller surface of the feed roller 22, and then moves upwards over the upper roller surface of the tension roller 24, thereby providing tension to the sheet-like substrate 5 by the tension roller 24. After passing through the tension roller 24, the sheet-like substrate 5 enters the adhesive coating assembly 3.

[0034] Reference Figure 1 The adhesive application assembly 3 includes an adhesive storage box 32, an adhesive application roller 33, a pressure roller 35, and a leveling roller 34. The adhesive storage box 32 is fixedly connected to the support frame 1. The adhesive application roller 33, pressure roller 35, and leveling roller 34 are all mounted on the support frame 1. The adhesive application roller 33 is located above the bottom of the adhesive storage box 32, and part of the adhesive application roller 33 is located inside the adhesive storage box 32. The leveling roller 34 is located on one side of the adhesive application roller 33, and the leveling roller 34 is also located above the bottom of the adhesive storage box 32, and part of the leveling roller 34 is located inside the adhesive storage box 32. The leveling roller 34 is also in contact with the adhesive application roller 33. The pressure roller 35 is located above the adhesive application roller 33 and is used to press the sheet-like substrate 5 onto the adhesive application roller 33. A discharge guide roller 36 is also rotatably connected to the support frame 1, and the discharge guide roller 36 is located on one side of the adhesive application roller 33. The discharge guide roller 36 is used to guide the sheet substrate 5 that has been coated with glue to the next processing step. A glue tank 37 is also fixedly connected to the support frame 1. The glue tank 37 is located at the upper end of the glue storage box 32. A glue discharge tube 371 is vertically connected to the lower bottom wall of the glue tank 37. The glue discharge tube 371 communicates with the glue tank 37. The end of the glue discharge tube 371 faces the glue storage box 32. A valve 372 is fixedly connected to the glue discharge tube 371.

[0035] Reference Figure 2A lifting cylinder 31 is installed below the glue storage box 32. The lifting cylinder 31 is vertically fixed to the support frame 1, and the end of the piston rod of the lifting cylinder 31 is fixedly connected to the bottom wall of the glue storage box 32. When it is necessary to clean, replace or maintain the glue coating roller 33 and the glue leveling roller 34, the lifting cylinder 31 can be activated to retract its piston rod, thereby driving the entire glue storage box 32 to descend vertically, thus separating the glue storage box 32 from the glue coating roller 33 and the glue leveling roller 34, providing sufficient operating space for subsequent operations.

[0036] Reference Figures 3-4 The support frame 1 has two first grooves 11 along its length. A first support block 41 is rotatably connected to each end of the long shaft of the glue-spreading roller 34. The two first support blocks 41 correspond one-to-one with the two first grooves 11, and each first support block 41 is slidably connected within a first groove 11. An adjustment assembly 4 is also installed on the support frame 1. The adjustment assembly 4 includes an adjustment screw 42. In this embodiment, two adjustment screws 42 are provided, both mounted on the support frame 1. Each adjustment screw 42 is also connected to a first support block 41. The adjustment screws 42 are used to adjust the tightness between the glue-spreading roller 34 and the glue-coating roller 33, thereby adjusting the film thickness on the circumferential sidewall of the glue-coating roller 33.

[0037] Reference Figures 2-4 Both the leveling roller 34 and the coating roller 33 are immersed in the glue storage box 32. The leveling roller 34 and the coating roller 33 cooperate with each other, and the thickness of the glue film on the surface of the coating roller is adjusted by the tightness between the two: when the coating roller 33 has a lot of glue, the leveling roller 34 can squeeze and remove the excess glue on its surface; when the glue is less, the leveling roller 34 can replenish the glue to the coating roller 33, thereby effectively compensating for the fluctuation of the amount of glue applied caused by the change of the glue level and improving the uniformity of the glue application.

[0038] Reference Figures 3-4This embodiment uses one of the adjusting screws 42 and the first support block 41 connected to it as an example. The adjusting screw 42 is rotatably connected to the support frame 1, and the end of the adjusting screw 42 extends into the first slide groove 11 and is threadedly connected to the first support block 41. A first guide rod 13 is fixedly connected to the side wall of the first slide groove 11 away from the adjusting screw 42. The axis of the first guide rod 13 coincides with the axis of the adjusting screw 42, and the first guide rod 13 also slides with the first support block 41. A first spring 43 is sleeved on the first guide rod 13. One end of the first spring 43 abuts against the side wall of the first support block 41, and the other end of the first spring 43 abuts against the side wall of the first slide groove 11 away from the adjusting screw 42. The advantage of this design is that by setting the first spring 43, a pushing force can always be applied to the first support block 41, so that the first support block 41 has a tendency to move towards the adjusting screw 42. This thrust further ensures a tight engagement between the internal thread of the first support block 41 and the external thread of the adjusting screw 42, thereby creating a continuous and stable axial preload between the threaded pairs. This preload effectively enhances the self-locking performance of the threaded connection, preventing the adjusting screw 42 from accidentally rotating or loosening due to vibration or load changes during equipment operation. Furthermore, it maintains the stability of the clamping force between the glue-spreading roller 34 and the glue-applying roller 33, avoiding changes in the tightness caused by loose threads, and ensuring the consistency of the glue-applying process and the reliability of product quality.

[0039] Reference Figures 3-4 The support frame 1 has two second sliding grooves 12 along its height. A second support block 44 is rotatably connected to each end of the long shaft of the coating roller 33. Each second support block 44 corresponds to one of the two second sliding grooves 12, and each second support block 44 is positioned within a second sliding groove 12. The lower end of each second support block 44 presses against the bottom of the second sliding groove 12. A third support block 46 is rotatably connected to each end of the long shaft of the pressure roller 35. Each third support block 46 corresponds to one of the two second sliding grooves 12, and each third support block 46 is slidably connected within a second sliding groove 12. The adjustment assembly 4 also includes two adjustment cylinders 45, both mounted on the support frame 1. The piston rods of each adjustment cylinder 45 are fixedly connected to one of the third support blocks 46. The adjustment cylinders 45 are used to adjust the distance between the pressure roller 35 and the coating roller 33 to accommodate different thicknesses of the sheet substrate 5.

[0040] Reference Figures 3-4This embodiment uses one of the adjusting cylinders 45 and the third support block 46 connected to it as an example for explanation. The adjusting cylinder 45 is vertically arranged at the upper end of the support frame 1. The piston rod of the adjusting cylinder 45 extends into the second sliding groove 12, and the end of the piston rod is also fixedly connected to the upper end of the third support block 46. The adjusting cylinder 45 drives the third support block 46 to rise and fall through the piston rod, thereby driving the pressing roller 35 to rise and fall. The upper end of the second support block 44 is vertically fixedly connected to a second guide rod 441. The second guide rod 441 slides with the third support block 46. A second spring 47 is sleeved on the second guide rod 441. One end of the second spring 47 abuts against the upper end of the second support block 44, and the other end of the second spring 47 abuts against the lower end of the third support block 46. The advantage of this design is that the second spring 47 always applies a vertically upward elastic support force to the third support block 46. This elastic support force is opposite to the direction of the weight of the components such as the pressure roller 35 and the third support block 46. In this way, the support force required by the adjusting cylinder 45 to maintain the position of the pressure roller 35 is reduced, which not only reduces the actual load on the cylinder but also extends the service life of the cylinder. At the same time, it helps to improve the stability and response accuracy of the system during the adjustment process.

[0041] The implementation principle of the automatic coating device for composite adsorbent materials in this application embodiment is as follows: The sheet substrate 5 is introduced through the feed guide roller 21, conveyed by the feed roller 22, and then tensioned by the tension roller 24 before entering the coating assembly 3. The coating roller 33 is partially immersed in the adhesive in the adhesive storage box 32, and adheres to the adhesive as it rotates; the evenly coating roller 34 is partially immersed in the adhesive and adheres to the coating roller 33, which can squeeze out excess adhesive when there is too much adhesive and replenish adhesive when there is too little adhesive, thereby significantly suppressing the problem of reduced coating amount caused by the drop in adhesive level and ensuring uniform adhesive film thickness. The pressure roller 35 presses the sheet substrate 5 against the surface of the coating roller 33 to evenly coat the adhesive. The coated sheet substrate 5 is output through the discharge guide roller 36.

[0042] The glue tank 37 replenishes glue to the glue storage box 32 via the glue pipe 371, and the glue replenishment rate is controlled by the valve 372. The adjusting screw 42 adjusts the clamping force between the glue spreading roller 34 and the glue coating roller 33 via the first support block 41. The first spring 43 enhances the self-locking of the threads to prevent loosening and ensure uniform glue film thickness. The adjusting cylinder 45 drives the third support block 46 to raise and lower the pressure roller 35 to adapt to different sheet substrate thicknesses; the second spring 47 offsets part of the weight of the pressure roller 35, reducing the load on the adjusting cylinder 45.

[0043] This application overcomes the problem of uneven coating caused by changes in the adhesive level by using the cooperation of the leveling roller 34 and the coating roller 33, combined with the precise control of the clamping force of the leveling roller by the adjusting screw 42, thus ensuring the uniformity of the adhesive film thickness. The structure of the clamping roller 35 and the adjusting cylinder 45 improves the adaptability to sheet substrates 5 of different thicknesses. Ultimately, this effectively improves the uniformity of coating, avoids problems such as uneven distribution of adsorbed components and fluctuations in interlayer bonding force, and enhances product quality stability and batch consistency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
