Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and in particular to an elastic glue injection device. Background Technology

[0002] Hand-held stress-relieving toys, as consumer products with stress-reducing functions, are widely used in learning and office settings. These toys are generally filled with an elastic rubber material with good extensibility, resilience, and high viscoelasticity. The raw materials are typically composed of a composite of foaming powder and thickener, which, after mixing, form an elastic colloid with foaming properties. This foaming characteristic can easily lead to air bubbles forming during the filling process, causing pressure imbalances and affecting the stability and consistency of the filling.

[0003] Traditional injection systems lack stable constant pressure during operation, especially in actual production processes where frequent start-ups and shutdowns lead to significant pressure fluctuations between different nodes within the system. This pressure unevenness causes fluctuations in injection volume, and may even result in intermittent output of the elastic adhesive or the appearance of air bubbles, severely impacting the quality of the final product. Furthermore, residual air in the pipelines cannot be effectively expelled, and the instability of material density during the injection process also negatively affects injection accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an elastic adhesive injection device. This injection device offers higher stability and precision in elastic adhesive injection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elastic adhesive injection device includes: a storage component, a conveying component, a conveying channel, a pressure regulating component, and a pneumatic control component; the storage component is used to store compressible elastic adhesive; the conveying component is installed at the bottom of the storage component and communicates with the storage component to pressurize and output the elastic adhesive; one end of the conveying channel is connected to the output side of the conveying component, and the other end is at least partially disposed above the storage component to realize the return of the elastic adhesive to the storage component; an injection section is provided in the middle of the conveying channel for injecting and outputting the elastic adhesive; the pressure regulating component is disposed at the end of the conveying channel away from the conveying component; the pneumatic control component is connected to the pressure regulating component to provide a constant air pressure to the pressure regulating component.

[0007] Furthermore, the storage component includes a material cylinder with a generally conical bottom, and a conveying component is disposed at the bottom of the material cylinder.

[0008] Furthermore, the pressure regulating component includes a pressure relief valve, and the pneumatic control component includes a breather valve and a constant pressure air source. The constant pressure air source is connected to the pressure relief valve through the breather valve to form a constant pressure module. The constant pressure module is used to balance the pressure in the delivery channel.

[0009] Furthermore, the conveying channel is connected to a return channel via a constant pressure module, which is used to guide the elastic adhesive to the top of the storage component.

[0010] Furthermore, a bypass channel is provided between the pressure regulating component and the return channel, and a damping structure is provided in the bypass channel to mitigate the pressure shock generated during the instantaneous return of material.

[0011] Furthermore, the storage container is equipped with a stirring device to prevent the elastic rubber from settling or separating during storage.

[0012] Furthermore, the injection device also includes a control module and several pressure detection modules; the pressure detection modules are distributed within the delivery channel; the pressure regulating component and the pressure detection modules are respectively connected to the control module; the control module controls the opening and closing of the pressure regulating component based on the pressure data detected by the pressure detection modules.

[0013] The aforementioned elastic adhesive injection device, through a material transfer and injection system composed of components such as a storage unit, a conveying unit, a conveying channel, a pressure regulating unit, and a pneumatic control component, achieves a stable injection process for elastic adhesive. This significantly improves the flow stability of material conveying and injection, resolving issues such as intermittent output, bubble formation, and inconsistent injection, thereby enhancing product quality and production efficiency.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 As shown, this application provides an elastic adhesive injection device, which includes: a storage component 1, a conveying component 2, a conveying channel 3, a pressure regulating component 4, and a pneumatic control component 5.

[0017] Specifically, the storage unit 1 is used to store compressible elastic adhesive. The conveying unit 2 is installed at the bottom of the storage unit 1 and communicates with it, for pressurizing and outputting the elastic adhesive. One end of the conveying channel 3 is connected to the output side of the conveying unit 2, and the other end is at least partially located above the storage unit 1, for allowing the elastic adhesive to flow back to the storage unit 1. A filling section 31 is provided in the middle of the conveying channel 3 for filling and outputting the elastic adhesive. A pressure regulating component 4 is located at the end of the conveying channel 3 away from the conveying unit 2. A pneumatic pressure control component 5 is connected to the pressure regulating component 4 and is used to provide a constant pneumatic pressure to the pressure regulating component 4.

[0018] The above-mentioned design effectively improves the pressure fluctuation problem caused by elastic rubber foaming during the filling process in traditional systems. The pressure regulating component 4 and the air pressure control component 5 ensure the stability of system operation, reduce the possibility of intermittent material output and uneven pressure within the conveying channel 3 caused by air bubble generation, and simultaneously improve the uniformity and repeatability of the filling process. The reflux design of the conveying channel 3 enhances the closed-loop flow within the system, helping to eliminate residual gas and stabilize density distribution, thereby improving filling accuracy.

[0019] More specifically, the storage unit 1 includes a material cylinder with a generally conical bottom, and the conveying unit 2 is disposed at the bottom of the material cylinder. The use of a conical material cylinder structure can effectively reduce dead corners and residues of material, improve material utilization, and at the same time ensure that the material supplied to the conveying unit 2 is more uniform and stable, significantly reducing problems such as flow interruption, air bubbles or uneven density during filling.

[0020] The pressure regulating component 4 includes a pressure relief valve, and the air pressure control component 5 includes a breather valve 51 and a constant pressure air source 52. The constant pressure air source 52 is connected to the pressure relief valve through the breather valve 51 to form a constant pressure module 6. The constant pressure module 6 is used to balance the pressure within the delivery channel 3. The constant pressure module 6 significantly improves the stability of the injection process, avoids material impact and intermittent output caused by internal system pressure fluctuations, and enhances the controllability and consistency of the injection flow rate. Simultaneously, by rationally configuring the pressure relief valve and the breather valve 51, the system's response sensitivity and adjustment accuracy can be improved while ensuring safety, effectively addressing the problems of sluggish pressure control and difficulty in responding to real-time load changes in traditional injection equipment.

[0021] The conveying channel 3 is connected to a return channel via the constant pressure module 6. The return channel guides the elastic adhesive to the top of the storage component 1. This structure significantly improves the system's control over material flow. By setting up the return channel, not only is the pressure regulation function improved, but the material circulation path is also optimized, effectively alleviating the pressure differential problem that is prone to occur in traditional injection systems and improving the stability of the entire injection system.

[0022] A bypass channel is provided between the pressure regulating component 4 and the return channel. The bypass channel is equipped with a damping structure to mitigate the pressure shock generated during material return. By setting up the bypass channel and damping structure, the system's resistance to pressure fluctuations is effectively improved, the pressure instability within the system during return is significantly reduced, and the risk of equipment vibration and mechanical fatigue is decreased.

[0023] The storage unit 1 is equipped with a stirring device to prevent the elastic rubber from settling or separating during storage, effectively maintaining the homogeneity of high viscosity or elastic rubber during standing, and improving the consistency and stability of the injection material.

[0024] The filling device also includes a control module and several pressure detection modules; the pressure detection modules are distributed within the conveying channel 3; the pressure regulating component 4 and the pressure detection modules are respectively connected to the control module; the control module controls the opening and closing of the pressure regulating component 4 based on the pressure data detected by the pressure detection modules. By introducing the control module and pressure detection modules, a multi-point monitoring, real-time response, and automatic adjustment intelligent control system is formed, significantly improving the automation level and precision control capability of the filling process. This system can effectively eliminate human operation errors and avoid problems such as uneven filling, intermittent output, or air bubbles caused by pressure fluctuations. At the same time, the data acquisition function helps to track the status of the filling process, realizing visualization of equipment operation status and operation and maintenance optimization.

Various modifications to these embodiments will be readily apparent to those skilled in the art.
