Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, and in particular to an adhesive application device for uniformly coating the inner layer of a full-light-blocking Oxford cloth. Background Technology

[0002] Blackout Oxford cloth is a functional fabric that achieves blackout through a special process. It also has the properties of wear resistance, flexibility, water resistance, and flame retardancy. It is widely used in home blackout, outdoor equipment, and industrial protection. With its advantages of high efficiency in blackout, durability, energy saving, and easy installation, it has become the preferred material in many fields. The inner layer uniform coating device addresses the problems of high difficulty, poor precision, and low efficiency in traditional coating methods for inner layers. It achieves high precision, high efficiency, and high adaptability of adhesive layer coating through innovative coating methods and intelligent control. It is widely used in packaging, automotive, electronics and other industries. It is the core equipment to meet the needs of precision coating of inner layers of materials and continues to be upgraded with the promotion of automation technology.

[0003] A uniform adhesive coating device for the inner layer of blackout Oxford cloth typically consists of a frame structure, a transmission module, and an adhesive coating device. The device unfolds the fabric via an unwinding mechanism and positions it using guide rollers. Adhesive is precisely supplied by a storage tank and a metering pump. The adhesive is then uniformly coated onto the inner layer of the fabric using a doctor blade and roller coating heads. The accuracy is dynamically calibrated by an online detection and closed-loop control device. Finally, the entire process is completed via a drying, curing, and rewinding mechanism, ensuring uniform adhesive coating and blackout performance.

[0004] Existing uniform adhesive coating devices for the inner layer of blackout Oxford cloth cannot guarantee that the Oxford cloth will not shift, resulting in decreased coating accuracy, large deviations in adhesive layer thickness, misalignment of coating position, uneven light-blocking performance, increased equipment wear and tear on rollers, coating head failure, increased maintenance costs, reduced production efficiency, frequent downtime for adjustments, a surge in scrap rate, poor process stability, difficulty in adapting to high-tension or special materials, failure of multi-process linkage, high dependence on manual intervention, lack of intelligent correction, difficulty in data traceability, and limited automation level. The core problems lie in the insufficient stability of the transmission device, the lack of a correction mechanism, or the lag in detection feedback. Optimization is needed in aspects such as tension closed-loop control, upgrading of dynamic correction mechanism, and intelligent visual monitoring. Therefore, a uniform adhesive coating device for the inner layer of blackout Oxford cloth is proposed to solve the above problems. Utility Model Content

[0034] Example 1

[0035] Reference Figures 1 to 3 This utility model provides an embodiment of a device for uniformly coating the inner layer of a full-light-blocking Oxford cloth. The base 1 provides stable support for the device, ensuring the installation accuracy and smooth operation of each component. A control panel 2 is fixedly connected to the outside of the base 1. The control panel 2 integrates operation buttons and parameter display functions, making it convenient for operators to adjust the operating status of the device. Two supports 3 are fixedly connected to the top of the base 1. The two supports 3 adopt a symmetrical structure design to provide an installation base for roller 4. Roller 4 is slidably connected inside the two supports 3. Roller 4 is used to load uncoated Oxford cloth rolls and can be flexibly picked up and placed along the internal track of the supports 3.

[0036] A glue applicator 10 is fixedly connected to the top of the base 1. The glue applicator 10 is the core component for achieving inner layer glue application. It has a coating mechanism inside to apply glue evenly to the Oxford cloth. Two fixing blocks 5 are fixedly connected to the outside of the glue applicator 10. The two fixing blocks 5 are symmetrically distributed on both sides of the glue applicator 10 and are used to install the rotating cylinder 7 assembly. Two placement slots 9 are opened inside each of the two fixing blocks 5. The placement slots 9 provide sliding space for the sliding rod 6, so that the rotating cylinder 7 can move along the inner side of the fixing block 5.

[0037] Springs 8 are fixedly connected inside both placement slots 9. Springs 8 provide elastic support for the rotating cylinder 7, keeping it in contact with the Oxford cloth. A sliding rod 6 is fixedly connected to the other end of spring 8. The sliding rod 6 can slide axially within the placement slot 9, transmitting the elastic force of spring 8 and guiding the movement direction of the rotating cylinder 7. The outer side of the sliding rod 6 is slidably connected inside the placement slot 9, and the distance between the rotating cylinders 7 can be dynamically adjusted through sliding cooperation. The rotating cylinder 7 is rotatably connected to the outer side of the sliding rod 6. The rotating cylinder 7 directly contacts the Oxford cloth. The elastic force of spring 8 limits the movement of the cloth and suppresses its deviation. The two sides of the rotating cylinder 7 are slidably connected to the inner side of the fixed block 5 to ensure the stability and guidance of the rotating cylinder 7 during movement.

[0038] Two fixed brackets 11 are fixedly connected to the outer side of the base 1. The two fixed brackets 11 are used to install the second roller 17 to form a winding mechanism. A limiting rod 16 is slidably connected inside the fixed bracket 11. The limiting rod 16 can slide along the internal track of the fixed bracket 11 to realize the installation and removal of the second roller 17. The second roller 17 is fixedly connected to the outer side of the limiting rod 16. The second roller 17 is used to wind up the glued Oxford cloth. It can be quickly replaced as the limiting rod 16 moves. The outer side of the second roller 17 is rotatably connected to the inner side of the fixed bracket 11 to ensure the flexible rotation of the second roller 17 during the winding process.

[0039] Example 2

[0040] Reference Figure 1 , Figure 2 and Figure 4 Both fixed frames 11 have slidably connected limiting components inside. These limiting components lock the second roller 17 to prevent accidental disengagement. Each limiting component includes two sliding rods 12, which pass through the fixed frame 11 and the limiting rod 16, providing an interface for locking and unlocking. The outer side of each sliding rod 12 is slidably connected to the outer side of the limiting rod 16 and can move axially along the limiting rod 16. A second spring 13 is fixedly connected inside each sliding rod 12, providing a return force to the sliding block 14 to ensure the reliability of the locked state. The outer side of each sliding rod 12 is slidably connected inside the fixed frame 11, and the overall limiting component is realized through sliding cooperation with the fixed frame 11. The sliding rod 12 has two sliding blocks 14 inside. Under the action of spring 13, the sliding blocks 14 can pop out and lock into the slot 15 to achieve mechanical locking of the roller 17. The other end of spring 13 is fixedly connected to the inner side of the sliding block 14. The spring force pushes the sliding block 14 to tightly engage with the slot 15. The outer side of the sliding block 14 is slidably connected to the inside of the slot 15. The slot 15 is opened inside the fixed frame 11 and forms a geometric limiting structure with the sliding block 14 to prevent the roller 17 from axially dislodging. The fixed frame 11 has two slots 15 inside. The two slots 15 are symmetrically distributed and cooperate with the sliding block 14 to achieve bidirectional locking of the limiting rod 16.

[0041] Work steps

[0042] Step 1: When the worker needs to apply glue to the Oxford cloth, first place the roller 4 wrapped with Oxford cloth on top of the support 3. Then, pass one end of the Oxford cloth through the inside of the glue applicator 10 and wrap it around the outside of the roller 17. At this point, the glue applicator 10 can be started to process the Oxford cloth inside, while the processed Oxford cloth will be wrapped around the outside of the roller 17. The thickness of the Oxford cloth can be changed according to different customer requirements. When encountering thicker Oxford cloth, the two rotating cylinders 7 will be squeezed in different directions. The upper rotating cylinder 7 will be pushed upward by the Oxford cloth, and the spring 8 will be squeezed by the sliding rod 6. The lower rotating cylinder 7 will squeeze the spring 8 downward. At this time, the rotating cylinder 7 can be automatically adjusted according to different thicknesses to prevent the position of the Oxford cloth from shifting.

[0043] Step 2: After wrapping the outer side of roller 2 17 with Oxford cloth, pull the sliding rod 2 12 outward to move the sliding block 14 outward. The sliding block 14 will be squeezed and slide into the inside of the sliding rod 2 12. This will allow the sliding block 14 to disengage from the slot 15 and the sliding rod 2 12 to be removed. Then, the limiting rod 16 can be removed from the inside of the fixing frame 11. Finally, the new roller 2 17 can be placed in its original position.

[0044] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
