Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a structural adhesive application process device for unitized curtain walls and component-type curtain walls. Background Technology

[0002] The construction industry is booming, and as a key component of modern building facades, the importance of curtain walls in their processing and assembly is self-evident. Curtain walls not only bear the heavy responsibility of showcasing the aesthetics of a building's exterior, but also serve as a solid defense to ensure the overall structural stability and safety of the building. Therefore, the quality of curtain wall processing cannot be compromised in the slightest.

[0003] Traditional curtain wall caulking processes have gradually revealed numerous drawbacks over time. Traditionally, the caulking tools and scrapers are separate, requiring frequent tool switching during construction. This is not only cumbersome but also prone to glue spillage and waste due to timing differences. Furthermore, the caulking and scraping processes are separate, relying on manual operation. Workers first use a conventional caulking gun to apply the caulking, but due to the difficulty in precisely controlling the dispensing speed and amount, glue overflow frequently occurs, leaving glue residue on the curtain wall surface. This not only severely affects aesthetics but also requires significant manpower and time for subsequent cleaning. Moreover, the subsequent manual scraping with a scraper greatly limits overall processing efficiency, especially in large-scale curtain wall projects or projects with tight deadlines, where the low efficiency of manual caulking and scraping becomes a major bottleneck restricting project progress.

[0004] As the construction industry demands increasingly stringent requirements for construction efficiency, quality control, and cost control, traditional sealant application methods can no longer meet current needs. The market urgently needs an innovative solution to break through the limitations of existing sealant application processes and achieve a highly efficient integration of sealant application and scraping. Against this backdrop, the development of a new type of sealant head that can solve both sealant application and scraping problems in a one-stop solution, significantly improving curtain wall processing efficiency and quality while reducing the negative impact of manual intervention, can inject new vitality into the building curtain wall processing field and propel the industry into a new stage of development. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a structural adhesive application process device that can achieve seamless connection between applying adhesive and scraping adhesive, thereby greatly improving construction efficiency and quality.

[0006] This utility model provides the following technical solution:

[0007] This utility model provides a structural adhesive application process device, which includes:

[0008] The main body of the glue head has an adhesive channel inside;

[0009] The glue outlet is located at the end of the glue channel and is used to extrude the glue.

[0010] The scraper, connected to the glue outlet, is used to shape the extruded glue.

[0011] Preferably, the scraper is detachably connected to the glue outlet.

[0012] Furthermore, the glue outlet is an arc-shaped glue outlet, preferably a semi-circular glue outlet or a semi-elliptical glue outlet.

[0013] Preferably, the glue outlet is located at the front end of the scraper.

[0014] Preferably, the cross-section of the adhesive channel has a gradually tapering structure with a contraction angle of 2°-5°. The shape and size of this channel are precisely designed considering the rheological properties of the adhesive, as well as the complex working conditions and precise requirements of curtain wall adhesive application. Specifically, since the adhesive typically has a high viscosity, a relatively wide design is used at the inlet of the channel to ensure smooth flow. As the adhesive progresses within the channel, the channel gradually narrows appropriately, thereby ensuring that the adhesive maintains a stable flow rate and pressure throughout the entire application process.

[0015] Furthermore, the width of the inlet end of the adhesive channel is greater than the width of the outlet end, and the width ratio is (7-15):1.

[0016] Preferably, the edge of the scraper is arc-shaped or wedge-shaped.

[0017] Furthermore, the rubber head body is provided with an auxiliary installation structure.

[0018] Preferably, the auxiliary installation structure is a threaded structure, which is disposed at the inlet end of the adhesive channel.

[0019] Preferably, the structural adhesive application apparatus further includes a lifting valve plate, which is disposed inside the adhesive channel to control the opening and closing of the adhesive channel.

[0020] Preferably, the structural adhesive dispensing apparatus further includes a control component, which is electrically connected to the dispensing head and the lifting valve plate to regulate the dispensing and control the opening and closing of the lifting valve plate.

[0021] Through the above design scheme, the beneficial effects of this utility model are:

[0022] This invention employs a clever structural design to connect the glue outlet and the scraper, forming an organic whole. When the glue is squeezed out of the glue gun, the scraper can immediately organize and shape the squeezed glue, ensuring that the glue can accurately fill the gaps in the curtain wall and scrape off the excess in the first instance. This achieves a seamless connection between applying and scraping the glue, greatly improving construction efficiency and quality.

[0023] The structural adhesive dispensing device of this invention features a highly scientific and targeted design for the adhesive channel inside the dispensing head. By designing the adhesive channel as a structure with a gradually narrowing width, the resistance during adhesive flow is effectively reduced, ensuring that the adhesive maintains a stable flow rate and pressure throughout the dispensing process, thus providing a strong guarantee for precise adhesive extrusion.

[0024] By carefully optimizing the shape of the dispensing nozzle, using a circular or elliptical geometry, the adhesive is extruded from the nozzle, forming a uniform adhesive strip with a relatively even pressure distribution in all directions. This allows the adhesive to be extruded at a stable and continuous flow, effectively preventing clogging or intermittent flow, ensuring the continuity and stability of the dispensing operation, and further improving the reliability and accuracy of the dispensing process.

[0025] By setting up a lifting valve and control system, the lifting valve can be opened when glue needs to be dispensed and closed when use is paused or stopped, thereby achieving the effects of dust prevention and preventing glue solidification. Attached Figure Description

[0039] Example 1

[0040] Please see as follows Figure 1-6The structural adhesive dispensing apparatus shown includes: a dispensing head body 1, which has an adhesive channel 2 inside; an adhesive outlet 3, located at the end of the adhesive channel 2, for dispensing adhesive; a scraper 4, connected to the adhesive outlet 3, for shaping the extruded adhesive; a lifting valve 6, located inside the adhesive channel 2, for controlling the opening and closing of the adhesive channel 2; and a control component, electrically connected to the dispensing head body 1 and the lifting valve 6, for regulating the dispensing and controlling the opening and closing of the lifting valve 6.

[0041] Specifically, in this embodiment, the adhesive outlet 3 is located at the front end of the scraper 4, and the adhesive outlet 3 is semi-circular. When the adhesive is squeezed out from the adhesive outlet 3, it promotes the formation of a uniform adhesive strip, and the pressure distribution in all directions is relatively uniform, allowing the adhesive to be squeezed out at a stable and continuous flow rate, effectively preventing the adhesive from becoming clogged or intermittent. At the same time, while the adhesive is being dispensed from the adhesive outlet 3, the scraper 4 located at its rear end can immediately shape the adhesive, ensuring that the adhesive can accurately fill the gaps in the curtain wall, and scraping off excess adhesive in a very short time, thereby effectively preventing the adhesive from overflowing and solidifying.

[0042] Specifically, in this embodiment, the cross-section of the adhesive channel 2 is a tapered structure with a gradually narrowing width and a contraction angle of 3°; the ratio of the width at the inlet to the width at the outlet of the adhesive channel 2 is 15:1. The shape and size of the adhesive channel 2 are precisely designed by comprehensively considering the rheological characteristics of the adhesive, as well as the complex working conditions and precise requirements of curtain wall caulking. Specifically, since the adhesive usually has a high viscosity, in order to ensure that the adhesive can flow smoothly in the adhesive channel 2, a relatively wide design is adopted at the inlet of the adhesive channel 2. As the adhesive advances in the adhesive channel 2, the adhesive channel 2 gradually narrows appropriately, thereby ensuring that the adhesive can maintain a stable flow rate and pressure throughout the caulking process.

[0043] Specifically, in this embodiment, the scraper 4 and the glue outlet 3 are an integral structure.

[0044] Specifically, the glue head body 1 is provided with an auxiliary installation structure 5, which is a threaded structure and is located at the inlet end of the glue channel 2 and on the outside of the glue head body 1.

[0045] Specifically, the lifting valve plate 6 and the control system can open the lifting valve plate 6 when glue needs to be dispensed, and close the lifting valve plate 6 when use is paused or stopped, thereby achieving the effects of dust prevention and preventing glue solidification.

[0046] Example 2

[0047] The difference between this embodiment and embodiment 1 is that: in this embodiment, the cross-section of the adhesive channel 2 is a tapered structure with a gradually decreasing width and a contraction angle of 2°; the ratio of the width of the inlet end to the width of the outlet end of the adhesive channel 2 is 7:1; the scraper 4 and the adhesive outlet 3 are detachably connected and can be quickly replaced to adapt to different adhesive types or working conditions.

[0048] Example 3

[0049] The only difference between this embodiment and Embodiment 1 is that: in this embodiment, the cross-section of the adhesive channel 2 is a tapered structure with a gradually decreasing width and a contraction angle of approximately 3°; the ratio of the width at the inlet end to the width at the outlet end of the adhesive channel 2 is 10:1; and the outlet 3 is semi-elliptical.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
