Description

Technical Field

[0001] This utility model relates to the field of fluid control and coating technology, and in particular to a glue coating equipment. Background Technology

[0002] In the field of precision manufacturing, the accurate metering and delivery technology of high-viscosity adhesives has always been a key focus of the industry. In current industrial applications, pneumatically driven adhesive coating systems mainly adopt a single-pump pressure control scheme, which achieves adhesive extrusion by adjusting the air pressure. These systems experience pressure decay during long-term continuous operation, affecting the uniformity of adhesive coating. To improve system stability, the industry has developed various pressure compensation technologies, including mechanical accumulators and electronic pressure feedback systems. At the same time, under high-pressure conditions, the sealing reliability of the adhesive storage container is crucial. Existing technologies mostly adopt multi-layer sealing structures and mechanical locking devices. In terms of adhesive delivery pipeline design, the use of sanitary connectors and anti-sedimentation structures has become an industry standard. These technologies provide basic solutions for the industrial application of high-viscosity adhesives, but there is still room for improvement in stability and reliability under extreme conditions.

[0003] In existing adhesive application processes, traditional glue drums, once opened, are directly exposed to air, making them highly susceptible to curing due to oxidation and moisture absorption, resulting in glue waste. Manual application is not only inefficient but also struggles to ensure uniform coating, failing to meet the demands of precision operations. Significant residue remains after use further complicate the process, increasing material costs. Furthermore, existing equipment struggles to maintain stable pressure when conveying high-viscosity glues, leading to uneven glue output and severely impacting coating quality and production stability. Therefore, we propose an adhesive application equipment to address these issues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this invention is to provide an adhesive coating equipment that solves the problems in existing adhesive coating operations. Traditional adhesive containers, once opened, are directly exposed to air and are prone to curing due to oxidation and moisture absorption, leading to adhesive waste. Manual application of adhesive is not only inefficient but also struggles to ensure uniform coating, failing to meet the demands of precision operations. Furthermore, significant residue remains after use, making complete utilization difficult and increasing material costs. In addition, existing equipment struggles to maintain stable pressure when conveying high-viscosity adhesives, resulting in uneven adhesive output and severely impacting coating quality and production stability.

[0006] To solve the above-mentioned technical problems, this utility model provides a glue-applying liquid equipment, which adopts the following technical solution: It includes a base, on which a pressure-applying glue storage cylinder is installed at the top by bolts. A sealing cover is installed at the top of the pressure-applying glue storage cylinder by locking. A disposable glue container is provided inside the pressure-applying glue storage cylinder. A glue delivery pipeline is provided on the cylinder wall by interference fit and welding reinforcement. One end of the glue delivery pipeline extends into the disposable glue container, and the other end passes through the wall of the pressure-applying glue storage cylinder and is located outside the cylinder.

[0009] Optionally, a pressure relief assembly is fixedly connected to the left rear of the pressure-applying storage cylinder. The pressure relief assembly includes a pressure regulating valve, a pressure relief pipe, and a fixing clamp. The fixing clamp installs the pressure relief pipe to the left rear of the pressure-applying storage cylinder and connects the pressure relief pipe to the top of the base through a bend connector. A pressure regulating valve is provided at the front end of the internal part of the pressure relief pipe. The pressure relief pipe connects the pressure-applying storage cylinder to the pressure control module, so that the released pressure can flow back to the pressure control module through the pipe, realizing the recycling of pressure.

The control handle is provided at the middle of the connecting rod by a nut.

[0012] Optionally, the sealing cover is equipped with a pressure-triggered limiting device that can move vertically up and down by means of a linear guide rail. When the pressure-applying glue reservoir begins to release pressure, the pressure-triggered limiting device will move upward against gravity due to the pressure, and then limit the rotation limiting mechanism by means of a slot and a boss, so that the rotation limiting mechanism cannot rotate and is restricted on the limiting slide rail, thereby locking the sealing cover and improving the safety of equipment use.

[0013] Optionally, the front of the base is provided with a door panel by means of axial connection via hinges. The door panel facilitates the replacement and installation of the first pneumatic drive pump and the second pneumatic drive pump.

Furthermore, when conveying high-viscosity glues, existing equipment struggles to maintain stable pressure, resulting in uneven glue output and severely impacting coating quality and production stability. Therefore, this utility model discloses a glue coating equipment.

[0032] The system includes a base 1, to which a pressure-pressurized glue storage cylinder 2 is bolted and mounted on top. A sealing cap 51 is locked onto the top of the pressure-pressurized glue storage cylinder 2. Inside the cylinder 2 is a disposable glue container 22. The cylinder wall of the cylinder 2 is reinforced with an interference fit and welding, and a glue delivery pipe 23 is provided. One end of the glue delivery pipe 23 extends into the disposable glue container 22, and the other end passes through the wall of the pressure-pressurized glue storage cylinder 2 and is located outside the cylinder 2. A cleaning module 6 is installed inside the pressure-pressurized glue storage cylinder 2, with one end connected to the middle of the glue delivery pipe 23. A first pneumatic pump 31 and a second pneumatic pump 32 are placed inside the base 1. Both the first and second pneumatic pumps 31 and 32 are connected to the inside of the pressure-pressurized glue storage cylinder 2 via high-pressure air pipes 34. The base 1 provides a stable support foundation for the equipment. The pressure storage cylinder 2 is bolted to the top of the base 1 to ensure the stability of the storage structure. The top of the pressure storage cylinder 2 is fitted with a sealing cover 51 to effectively prevent glue evaporation and the entry of external impurities. A disposable glue container 22 is installed inside to facilitate glue replacement and avoid contamination between different batches of glue. The cylinder wall adopts an interference fit and welded reinforcement of the glue delivery pipeline 23 to ensure that the glue delivery process is leak-free, stable and reliable. The first pneumatic drive pump 31 and the second pneumatic drive pump 32 are placed inside the base 1 and connected to the inside of the pressure storage cylinder 2 through a high-pressure air delivery pipe 34 to provide a stable power source for glue delivery. This achieves accurate, efficient and safe glue delivery and solves the problems of glue waste, uneven coating and low efficiency in traditional glue application methods.

[0033] A pressure control module is embedded in the rear of the base 1. The first pneumatic pump 31 and the second pneumatic pump 32 are electrically connected to the pressure control module through pressure transmission pipes and are connected to the front interface of the pressure control module. By embedding the pressure control module in the rear of the base 1, and connecting the first pneumatic pump 31 and the second pneumatic pump 32 to the pressure control module through pressure transmission pipes and connecting to the front interface, the output pressure of the two pneumatic pumps can be accurately adjusted and controlled. This achieves the purpose of stabilizing the glue delivery pressure, avoids the problem of uneven glue output caused by unstable pressure, effectively improves the accuracy and stability of the glue application operation, and realizes intelligent pressure management, thereby improving the operating efficiency and reliability of the equipment.

[0034] A pressure boosting module 3 is welded inside the pressurized glue storage cylinder 2. Two pressure relief connectors 33 are connected to the top of the pressure boosting module 3 via flanges. These two pressure relief connectors 33 are respectively connected to the first pneumatic pump 31 and the second pneumatic pump 32 via high-pressure air supply pipes 34. The pressure boosting module 3 is installed on the outer periphery of the pressurized glue storage cylinder 2, and this installation position is independent of the accommodating space of the disposable glue container 22. The pressure boosting module 3 is welded inside the pressurized glue storage cylinder 2, and its top is connected to two pressure relief connectors 33 via flanges, which are respectively connected to the first pneumatic pump 31 and the second pneumatic pump 32 via high-pressure air supply pipes 34. The pneumatic pump 31 and the second pneumatic pump 32 are respectively set through the high-pressure air supply pipe 34, and the pressurization module 3 is installed inside and outside the pressurized glue storage cylinder 2 and is independent of the space of the disposable glue container 22. This achieves the purpose of increasing the pressure and stabilizing the distribution of glue in the pressurized glue storage cylinder 2, and provides sufficient and stable pressure for glue delivery. This effectively solves the problem of insufficient and unstable pressure in the delivery of high-viscosity glue, while avoiding interference with the glue container during the pressurization process, and ensuring the safety and reliability of glue storage and delivery.

[0035] A pressure relief assembly 4 is fixedly connected to the left rear of the pressure-applying rubber storage cylinder 2. The pressure relief assembly 4 includes a pressure regulating valve 41, a pressure relief pipe 42, and a fixing clamp 43. The fixing clamp 43 installs the pressure relief pipe 42 to the left rear of the pressure-applying rubber storage cylinder 2 and connects the pressure relief pipe 42 to the top of the base 1 through a bend connector. The pressure regulating valve 41 is installed at the front end of the pressure relief pipe 42 through a threaded connection. The pressure relief pipe 42 connects the pressure-applying rubber storage cylinder 2 to the pressure control module, so that the released pressure can flow back to the pressure control module through the pipe, realizing the recycling of pressure. The pressure relief assembly 4, consisting of a pressure regulating valve 41, a pressure relief pipe 42, and a fixing clamp 43, uses the fixing clamp 43 to install the pressure relief pipe 42 at the left rear of the pressure storage cylinder 2 and connect it to the top of the base 1 via a bend connector. The pressure regulating valve 41 is threadedly connected to the front end of the pressure relief pipe 42, and the pressure relief pipe 42 is connected to the pressure storage cylinder 2 and the pressure control module. This achieves the purpose of precisely controlling the pressure release in the pressure storage cylinder 2, realizing the effect of returning the released pressure to the pressure control module for recycling, effectively avoiding pressure waste, reducing energy consumption, and ensuring that the pressure is within a safe and controllable range during equipment operation.

[0036] Two symmetrically distributed limiting slide rails 21 are fixedly connected to the outer wall of the pressurized rubber storage cylinder 2. A gap is reserved between the limiting slide rails 21 for the rotation limiting mechanism 52 to enter and exit. By fixing two symmetrically distributed limiting slide rails 21 to the outer wall of the pressurized rubber storage cylinder 2 and reserving a gap between the limiting slide rails 21 for the rotation limiting mechanism 52 to enter and exit, the purpose of providing a precise guide and positioning track for the rotation limiting mechanism 52 is achieved. This realizes a stable constraint effect on the rotation opening and closing process of the sealing cover 51, so that the sealing cover 51 can move along the predetermined trajectory when opening and closing, ensuring smooth operation and sealing.

[0037] It also includes a sealing assembly 5, which includes a sealing cover 51, a rotation limiting mechanism 52, and a pressure-triggered limiting device 53. The top center of the sealing cover 51 is provided with a rotation limiting mechanism 52 via an axial connection using a bearing and shoulder. The rotation limiting mechanism 52 includes a connecting rod 521, a limiting slider 522, and a control handle 523. The two ends of the connecting rod 521 are welded with fillet welds to provide the limiting sliders 522. The two limiting sliders 522 are mirror-shaped, and their height is greater than that of the sealing cover 51. The two limiting sliders 522 are respectively engaged with two limiting slide rails 21 via dovetail grooves for axial sliding. The middle of the connecting rod 521 is secured with a nut to provide the control handle 523. The sealing assembly 5, consisting of a rotary limiting mechanism 52 and a pressure-triggered limiting device 53, has a rotary limiting mechanism 52 installed at the top center of the sealing cover 51 via an axial connection using a bearing and shoulder positioning. The connecting rod 521 has mirror-image limiting sliders 522 welded to both ends via fillet welds, and these sliders engage with the limiting slide rail 21 via dovetail grooves to achieve axial sliding limitation. Simultaneously, a nut locks the control handle 523 in the middle of the connecting rod 521, facilitating flexible rotation and precise positioning of the sealing cover 51. This allows for easy operation of the sealing cover 51 when no pressure is applied, and when pressure is applied, the pressure-triggered limiting device 53, in conjunction with the rotary limiting mechanism 52, automatically locks the sealing cover 51 to prevent accidental opening, effectively improving the equipment's sealing performance and operational safety.

[0038] The sealing cover 51 is equipped with a pressure-triggered limiting device 53 that can move vertically up and down via a linear guide rail. When the pressure-applied glue reservoir 2 begins to release pressure, the pressure-triggered limiting device 53 will move upward against gravity due to the pressure, thereby limiting the rotation limiting mechanism 52 through the engagement of the slot 531 and the boss. This prevents the rotation limiting mechanism 52 from rotating and restricts it to the limiting slide rail 21, thus locking the sealing cover 51 and improving the safety of equipment use. By using a linear guide rail for sliding inside the sealing cover 51... A pressure-triggered limit device 53 that can move vertically up and down is provided. When the pressure-applied glue storage cylinder 2 releases pressure, the pressure-triggered limit device 53 is pushed upward by the pressure to overcome gravity. The slot 531 and the boss cooperate to limit the rotation limit mechanism 52, restricting the rotation limit mechanism 52 to the limit slide rail 21 and preventing it from rotating. This achieves the purpose of automatically monitoring the pressure and locking the sealing cover 51, preventing the sealing cover 51 from opening accidentally when the equipment is working, effectively avoiding glue leakage and pressure impact risks, and significantly improving the safety and stability of the equipment.

By providing the door panel 7 at the front of the base 1 via an axial connection using hinges, it is possible to quickly open the door panel 7 to replace, install, and maintain the first pneumatic pump 31 and the second pneumatic pump 32, thereby improving the convenience and efficiency of equipment maintenance. At the same time, by fixing several universal rollers 8 with braking devices to the bottom of the base 1 with screws, it is possible to facilitate flexible movement and precise positioning of the equipment, thereby enhancing the adaptability of the equipment to different usage scenarios and the ease of operation.

[0040] Inside the pressurized glue storage cylinder 2, directly to the right of the pressurization module 3, is a cleaning module 6. This cleaning module 6 includes a cleaning pipe 61; one end of the cleaning pipe 61 connects to the inside of the pressurized glue storage cylinder 2, and the other end connects to the middle of the glue delivery pipeline 23. After the equipment completes the glue application operation, the cleaning module 6 is activated, injecting cleaning fluid or high-pressure gas into the glue delivery pipeline 23 to flush and remove residual glue from the inner wall of the pipeline 23. This effectively prevents glue from hardening and clogging the pipeline, ensuring the smooth flow of the glue delivery system and the reliability of the equipment for future use. Inside the pressurization module 3, a cleaning module 6 consisting of a cleaning pipe 61 is installed directly to the right. One end of the cleaning pipe 61 is connected to the inside of the pressurized glue storage cylinder 2, and the other end is connected to the middle of the glue delivery pipeline 23. After the equipment completes the glue application, the cleaning module 6 is activated to inject cleaning liquid or high-pressure gas, which achieves the purpose of automatically removing residual glue from the inner wall of the glue delivery pipeline 23. This prevents the glue from hardening and clogging the pipeline, effectively ensuring the smoothness of the glue delivery system, improving the reliability of subsequent equipment use, reducing the frequency and cost of manual maintenance, and extending the service life of the equipment.

[0041] The specific working principle is as follows: The base 1 provides stable support for the equipment, the disposable glue container 22 inside the pressurized glue storage cylinder 2 facilitates glue replacement and prevents contamination, the sealing cover 51 ensures the glue storage is airtight, and the pneumatic pump provides power through the air supply pipeline. This achieves stable and efficient glue delivery, avoiding the problems of easy curing and waste after opening traditional glue containers, uneven application due to manual glue dispensing, and low efficiency. It improves coating accuracy and efficiency, reduces glue residue, and ensures stable and reliable coating operations. Through the installation of a pressure control module, a pressure boosting module 3, a pressure relief component 4, and a pressure trigger limit device 53, the pressure control module precisely adjusts the pressure of the pneumatic pump, the pressure boosting module 3 enhances the glue delivery pressure, the pressure relief component 4 enables pressure recycling, and the pressure trigger limit device 53 automatically locks the sealing cover 51 during pressurization. It achieves the goal of intelligent and safe control of equipment pressure, ensuring stable delivery pressure of high-viscosity colloids, avoiding pressure fluctuations from affecting coating quality, ensuring safe equipment operation, preventing accidental start-up and leakage, and improving the overall performance and reliability of the equipment.
