Description

Technical Field

[0001] This utility model relates to the technical field of glue supply mechanisms, specifically a novel vacuum glue supply mechanism. Background Technology

[0002] A standard glue supply system is a basic mechanical system that delivers glue from a storage container (such as a glue bucket) to a dispensing valve or application device. It uses pressure, pumping, or gravity to propel the glue and achieve the purpose of glue supply. Traditional glue supply systems require manual unscrewing of the discharge port when changing glue. The nut uses the pressure of a descending pressure plate to force the glue out. Due to structural limitations, the glue is not completely drained, leaving a large amount of unusable glue residue in the bucket. Furthermore, the timing of the defoaming process heavily relies on the experience of the person changing the glue, making consistency difficult to guarantee. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel vacuum glue supply mechanism. This solves the problems of traditional glue supply systems where, when changing glue, the glue outlet is manually unscrewed, and the glue is squeezed out by the pressure of the descending pressure plate. Furthermore, due to structural limitations, the glue is not completely used up, leaving a large amount of unusable glue residue in the container. Moreover, the timing of the defoaming process heavily depends on the experience of the person changing the glue, making it difficult to ensure consistency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel vacuum adhesive supply mechanism, comprising:

[0005] A sheet metal cover, the bottom of which is equipped with a universal brake wheel, a sealing door hinged to the surface of which is equipped with a three-color light on one side of the top of which is equipped with a vacuum pump fixedly connected to one side of the inner wall of which is equipped with a control box fixedly connected to one side of which is equipped with a human-machine panel on the surface of which is equipped with a control box.

[0006] A pneumatic control assembly, one side of which is fixedly connected to one side of the inner wall of the sheet metal cover, the pneumatic control assembly being an integrated pneumatic control module for a vacuum glue supply system;

[0007] The adhesive pressing assembly has its bottom fixedly connected to the bottom of the inner wall of the sheet metal cover. The adhesive pressing assembly is used to squeeze the adhesive in the bucket downwards and, in conjunction with vacuum suction, complete the dispensing of the adhesive.

[0008] Preferably, the pneumatic control assembly includes a pneumatic triplet, a pressure regulating valve, a speed regulating valve, and a glue dispensing pump assembly fixedly connected to one side of the inner wall of the sheet metal cover. The pneumatic triplet includes a filter, a slow-start valve, and an oil mist lubricator.

[0009] Preferably, the adhesive pressing assembly includes a glue tank base fixedly connected to the bottom of the inner wall of the sheet metal cover, and protective partitions are provided on both sides of the glue tank base.

[0010] Preferably, a glue bucket is fixedly connected to the top of the glue bucket base, and a handle is provided on the top of the glue bucket surface.

[0011] Preferably, a grating is fixedly connected to one side of the inner wall of the sheet metal cover, and a dual-pump assembly is fixedly connected to one side of the inner wall of the sheet metal cover.

[0012] Preferably, a connecting plate is fixedly connected to the back of the inner wall of the sheet metal cover, a pressure-pressing cylinder is fixedly connected to one side of the connecting plate, and a pipeline is fixedly connected to one side of the inner wall of the sheet metal cover.

[0013] This invention provides a novel vacuum adhesive supply mechanism. Compared with the prior art, it has the following advantages:

[0014] 1. This new type of vacuum glue supply mechanism utilizes the setting of the pressure assembly. When changing glue, the vacuum pump extracts air through the gap between the pressure plates until a small amount of glue is extracted into the gap of the vacuum pressure plates. The venting action is only completed after the vacuum is stabilized. In addition, the bottom structure of the vacuum pressure plate is relatively flat, and the glue can be used to the bottom of the bucket, with minimal glue loss. This solves the problem of traditional glue supply systems where glue is manually unscrewed from the discharge port and the nut is used to squeeze the glue out by the pressure of the descending pressure plate. Furthermore, due to structural limitations, the glue cannot be used to the bottom, and a large amount of glue remains in the bucket that is difficult to use. Moreover, the timing of defoaming depends heavily on the experience of the glue changer, making it difficult to ensure consistency.

[0015] 2. This new type of vacuum glue supply mechanism utilizes the pneumatic control components to form a closed loop within the air circuit, achieving integrated control of air source purification, pressure stabilization, slow start control, and output speed adjustment, thereby improving system stability and response speed and reducing air circuit failure rate.

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides two technical solutions:

[0024] Example 1: A novel vacuum adhesive supply mechanism, comprising:

[0025] Sheet metal cover 1, with universal brake wheel 2 at the bottom of sheet metal cover 1, a sealing door 3 hinged to the surface of sheet metal cover 1, a three-color light 4 on one side of the top of sheet metal cover 1, the three-color light 4 is used to remind the surrounding staff of the working status of the machine, a vacuum pump 5 is fixedly connected to one side of the inner wall of sheet metal cover 1, a control box 8 is fixedly connected to one side of sheet metal cover 1, and a human-machine panel 9 is provided on the surface of the control box 8.

[0026] Pneumatic control component 6, one side of which is fixedly connected to one side of the inner wall of sheet metal cover 1, is used as an integrated pneumatic control module for vacuum glue supply system;

[0027] The bottom of the glue-pressing assembly 7 is fixedly connected to the bottom of the inner wall of the sheet metal cover 1. The glue-pressing assembly 7 is used to squeeze the glue in the bucket downwards and complete the glue dispensing in conjunction with vacuum suction. With the setting of the glue-pressing assembly 7, when changing the glue, the vacuum pump 5 uses the gap between the pressure plates to extract air until a small amount of glue is extracted into the gap of the vacuum pressure plate. The venting action is only completed after the vacuum is stabilized. Moreover, the bottom structure of the vacuum pressure plate is relatively flat, and the glue can be used to the bottom of the bucket, with minimal glue loss. This solves the problem of traditional glue supply systems where the glue outlet is manually unscrewed and the nut is used to squeeze the glue out by the pressure of the descending pressure plate. In addition, due to structural limitations, the glue cannot be used to the bottom, and a large amount of glue remains in the bucket that is difficult to use. Furthermore, the timing of the defoaming is highly dependent on the experience of the glue-changing personnel, making it difficult to ensure consistency.

[0028] Example 2 differs from Example 1 primarily in that the novel vacuum glue supply mechanism includes a pneumatic control assembly 6 comprising a pneumatic triplet 61 fixedly connected to one side of the inner wall of the sheet metal cover 1, a pressure regulating valve 62, a speed regulating valve 63, and a glue dispensing pump assembly 64. The pneumatic triplet 61 includes a filter, a slow-start valve, and an oil mist lubricator. The filter removes moisture, oil, and particulate impurities from the compressed air, protecting downstream components such as the glue dispensing pump and solenoid valve. The pressure regulating valve 62 stabilizes the output air pressure, ensuring the glue dispensing pump operates at the set pressure without being affected by air supply fluctuations. The oil mist lubricator injects a small amount of lubricating oil into the airflow, protecting cylinders, valves, and other components and extending their lifespan. The slow-start valve gradually increases pressure to prevent instantaneous shock startup of the equipment, avoiding impact and damage to the glue circuit or pneumatic components caused by the glue dispensing pump's "instant start." The speed regulating valve 63 controls the operating speed of the cylinder or glue dispensing pump, controlling the glue dispensing speed. Speed ​​and rhythm improve the uniformity and precision of glue application. The glue pressing component 7 includes a glue bucket base 71 fixedly connected to the bottom of the inner wall of the sheet metal cover 1. Protective partitions are set on both sides of the glue bucket base 71. A glue bucket 72 is fixedly connected to the top of the glue bucket base 71. A handle is set on the top of the surface of the glue bucket 72. A grating 73 is fixedly connected to one side of the inner wall of the sheet metal cover 1. A dual pump component 74 is fixedly connected to one side of the inner wall of the sheet metal cover 1. The dual pump component 74 is an auxiliary mechanism of the pump body. A connecting plate 75 is fixedly connected to the back of the inner wall of the sheet metal cover 1. A glue pressing cylinder 76 is fixedly connected to one side of the connecting plate 75. A pipeline 77 is fixedly connected to one side of the inner wall of the sheet metal cover 1. The pipeline 77 connects the relevant working devices. With the setting of the pneumatic control component 6, the internal connection of the air circuit forms a closed loop, realizing integrated control of air source purification, pressure stabilization, slow start control and output speed adjustment, thereby improving system stability and response speed and reducing the air circuit failure rate.

[0029] Vacuum pressing plate: Flat structure, close to the glue surface, descends with the glue surface; Pressing plate drive mechanism: such as cylinder, electric push rod, etc., used to move the pressing plate up and down; Sealing ring: seals the glue barrel at the edge of the pressing plate, forming a closed environment with vacuum; Central extraction hole / guide hole: used to leave a gap under the pressing plate for negative pressure extraction; Guide rail / limiting structure: controls the movement path and stability of the pressing plate.

[0030] Using disposable pressure plates eliminates the need for extensive cleaning of dry adhesive when replacing them. The vacuum pump in this device employs a dual-stroke piston structure, completing the evacuation process in both strokes through reciprocating motion, thus improving evacuation efficiency and system negative pressure stability. It offers extremely high stability for supplying medium to high viscosity adhesives, optimizing production efficiency. The dual-stroke piston pump can provide uninterrupted adhesive supply, and its wear cycle is longer and maintenance costs are lower than those of a bidirectional piston pump. It features rapid response, minimal adhesive loss, and reduced overall costs over long-term use. It eliminates the need for a pressure regulating valve, simplifies manual operation, supports complex processes, boasts a long lifespan and low maintenance, and offers strong compatibility. The grating 73 provides real-time liquid level monitoring and alarm prompts for adhesive replacement when the liquid level is low. The safety door protection function effectively prevents potential personal safety hazards from the equipment.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the omnidirectional brake wheel 2 is moved to the working position, and the entire sheet metal cover 1 is moved. The equipment is operated through the human-machine panel 9. The device supplies glue normally, and the glue supply rate is stably controlled by the pneumatic control component 6. When changing the glue tank 72, the pressure cylinder 76 drives the pressure plate to perform the glue pressing operation. The grating 73 is used to monitor the position and displacement information of the pressure plate in real time, so that the equipment control system can judge the glue supply progress and the remaining glue in the glue tank, realizing functions such as automatic alarm, action switching, or pressure plate return, thereby effectively improving the degree of automation and safety of use. When the device is not in use, it is restored to its original state.
