Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and in particular to a glue mixing and flow monitoring device for a glue applicator. Background Technology

[0002] In the production and processing of building composite panels, especially cleanroom panels, an adhesive applicator is required. This adhesive applicator can mix at least two different types of adhesives and then evenly apply the mixed adhesive to the surface of the panels to be bonded, thereby achieving bonding between different sides of the cleanroom panel (such as the core panel and the face panel).

[0003] In the relevant technical solution, the glue applicator includes two separately arranged glue tanks. The two glue tanks are respectively connected to the inlet of the mixer through pipelines, and the outlet of the mixer is connected to the glue outlet pipe.

[0004] However, in the above technical solution, the separate arrangement of the two glue buckets occupies a large space on the glue applicator. In addition, the glue on the inner wall of the dispensing tube will only adhere and cannot be sprayed onto the glued surface of the board. Because the dispensing tube of the mixer and the glue applicator's spray head cannot restrict the movement of the spray head on the glued surface of the board, the dispensing tube needs to be of a long length, which will result in a significant waste of glue on the inner wall of the dispensing tube. Utility Model Content

[0005] This invention provides a glue mixing and flow monitoring device for a glue applicator, which can solve at least one of the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, one or more embodiments of this utility model provide a glue mixing and flow monitoring device for a glue applicator, including a base plate, a walking assembly installed on the lower part of the base plate, a mixer and a first and second barrel with a circular cross-section installed on the upper part of the base plate, the first and second barrels being connected to the two inlets of the mixer through glue pipes respectively, and the outlet of the mixer being connected to the glue outlet pipe; a glue pump and a flow meter are connected in series on the two glue pipes respectively, the flow meter being signal-connected to a controller, the controller being able to compare the flow meter signal with preset proportional data to control the speed of the glue pump, and the controller being signal-connected to an operation panel;

[0007] The inner diameter of the first bucket is larger than the outer diameter of the second bucket. The second bucket is coaxial with the first bucket and detachably installed in the inner cavity of the first bucket. The annular gap between the inner wall of the first bucket and the outer wall of the second bucket is used to store the first adhesive liquid, and the inner cavity of the second bucket is used to store the second adhesive liquid.

[0008] The beneficial effects of one or more of the above technical solutions are as follows:

[0009] In this solution, the base plate and the traveling assembly support the first bucket, the second bucket, and the mixer, etc. The traveling assembly can move synchronously with the action of the spray nozzle in the glue applicator. In other words, the glue outlet pipe required in this solution is shorter, which can reduce the waste of glue on the inner wall of the glue outlet pipe.

[0010] In this solution, the combined use of a controller and a flow meter can monitor the flow rate of the two hoses at all times, thereby ensuring that the two hoses can be mixed in a set ratio and that the content of each component in the mixed adhesive output from the mixer meets the requirements.

[0011] In this design, the second barrel is coaxially mounted inside the first barrel, thus avoiding gaps caused by the separation of the first and second barrels on the base plate; in addition, it facilitates the overall disassembly and assembly of the first and second barrels from the base plate, so as to make it easier to apply glue to the first and second barrels.

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0017] like Figures 1-3As shown, one or more embodiments of this utility model provide a glue mixing and flow monitoring device for a glue applicator, including a base plate 14. A walking assembly is installed on the lower part of the base plate 14, and a mixer 10 and a first barrel 2 and a second barrel 18 with a circular cross-section are installed on the upper part of the base plate 14. The first barrel 2 and the second barrel 18 are respectively connected to the two inlets of the mixer 10 through glue hoses. The outlet 21 of the mixer 10 is used to connect to the glue outlet pipe 12. Glue pumps (i.e., the first glue hose 7 and the second glue hose 15 shown in the figure) and a flow meter 24 are connected in series on the two glue hoses respectively. The flow meter 24 is signal-connected to a controller, which can compare the signal from the flow meter 24 with preset proportional data to control the speed of the glue pump. The controller is signal-connected to an operation panel 25.

[0018] The inner diameter of the first bucket 2 is larger than the outer diameter of the second bucket 18. The second bucket 18 is coaxial with the first bucket 2 and detachably installed in the inner cavity of the first bucket 2. The annular gap 23 between the inner wall of the first bucket 2 and the outer wall of the second bucket 18 is used to store the first adhesive, and the inner cavity of the second bucket 18 is used to store the second adhesive. The lower part of the first bucket 2 is supported on the base plate 14 by a bracket 1.

[0019] Specifically, the base plate 14 here is a flat plate structure, and the first barrel 2, the second barrel 18 and the mixer 10 are fixedly connected to the upper surface of the base plate 14 by bolts and other connecting parts.

[0020] Correspondingly, one end of the dispensing pipe 12 is connected to the outlet 21 of the mixer 10, and the other end is connected to the coating head of the glue applicator. In order to supply the mixed glue from the mixer 10 to the coating head, another glue pump (i.e., the third glue pump 11 shown in the figure) is provided on the dispensing pipe 12.

[0021] Specifically, the two tubing tubes are connected to the bottom of the first barrel 2 and the second barrel 18, respectively.

[0022] In this embodiment, the upper end of the first barrel 2 has a sealing top cover 4, which can fit against the upper surface of the second barrel 18 to achieve a seal on the second barrel 18. The top cover 4 is provided with a rotary drive assembly 5, the drive end of the rotary drive assembly 5 passes downward through the bottom cover and drives the second barrel 18 to rotate around its own central axis. The inner wall and outer wall of the second barrel 18 are respectively provided with stirring blades.

[0023] Specifically, the top cover 4 is a round cover, and its outer diameter is not less than that of the first tank 2. The top cover 4 is fixed to the first tank 2 by a snap-fit ​​3. Sealing gaskets are provided between the top cover 4 and the upper surface of the first tank 2, as well as between the upper surface of the second tank 18, to enhance the sealing effect of the two top covers 4. A viewing window 6 is provided on the first tank 2 to observe the liquid level inside.

[0024] Specifically, the hose on the second barrel 18 should not affect the rotation of the second barrel 18 around its own axis. To achieve this, the hose on the second barrel 18 can be installed on the bottom wall of the second barrel 18 near the center.

[0025] In order to enable the second barrel 18 to rotate around its own central axis, a shaft 20 can be provided at the bottom of the inner cavity of the first barrel 2, and a concave sleeve 22 can be provided on the second barrel 18. The shaft 20 and the sleeve 22 are respectively arranged coaxially with the central axis of the second barrel 18.

[0026] In this embodiment, the stirring blades are arranged in a spiral pattern on the inner and outer walls of the second barrel 18.

[0027] Specifically, the stirring blades on the inner wall of the second barrel 18 are the first blades, and the stirring blades on the outer wall of the second barrel 18 are the second blades 19. Both the first blade and the second blade 19 are spiral blades. By rotating the second barrel 18, the first blade and the second blade 19 can be rotated synchronously, thereby synchronously completing the stirring of the first adhesive and the second adhesive, so that the first adhesive and the second adhesive are evenly distributed in the storage space.

[0028] In this embodiment, the rotary drive assembly 5 includes a rotary motor, the housing of which is fixed to the top cover 4, and the output shaft of the rotary motor passes vertically downward through the top cover 4. The upper end of the second barrel 18 has a drive sleeve 17, which is fixed to the inner wall of the second barrel 18 by a connecting rod 16. The output shaft is inserted into the drive sleeve 17, and the output shaft and the drive sleeve 17 can be limited in the circumferential direction.

[0029] Specifically, the rotary motor here can be replaced with a hydraulic motor.

[0030] In this embodiment, there are multiple connecting rods 16, which are evenly distributed around the drive sleeve 17.

[0031] Specifically, the connecting rod 16 here is fixed to the inner wall of the second barrel 18 and the drive sleeve 17 by welding or bolting.

[0032] In this embodiment, the two glue pumps are driven by stepper motors respectively.

[0033] As can be seen, when a stepper motor is used to drive the glue pump to rotate, the precise adjustable speed of the stepper motor allows for more accurate adjustment of the glue pump speed, thereby precisely regulating the flow rate of different glue liquids in the two glue tubes.

[0034] In this embodiment, the walking assembly adopts a wheeled walking mechanism or a tracked walking mechanism. Taking a wheeled walking mechanism as an example, it has multiple wheels 13.

[0035] In this embodiment, the controller is a PLC controller 26, which is also connected to the display panel 27 and the sound and light alarm signal.

[0036] In other embodiments, the controller may also employ an ARM processor. This can be configured by those skilled in the art.

[0037] Working Principle: In order to monitor and mix the two adhesive solutions within the mixer 10, the controller presets the required ratio data. When the flow rate data from the two hoses is transmitted to the controller, the controller obtains the actual ratio data based on the two flow rate data and compares the actual ratio data with the preset ratio data. Furthermore, when the actual ratio data differs from the preset ratio data, the controller controls the rotation speed of the two adhesive pumps on the hoses to adjust the actual ratio data.

[0038] The application rates of the two adhesives during production can be monitored in real time and displayed graphically on the display panel. Historical application rate curves for both adhesives can be generated, providing a clear visual representation of changes in application rate. When the application rate exceeds a warning value, or the ratio of the two adhesives exceeds a warning threshold, an audible and visual alarm is triggered to alert on-site personnel. Furthermore, the controller can record application rate data for both adhesives, providing data support for adhesive analysis and research.

[0039] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0040] Any aspects of this utility model not described in detail are known to those skilled in the art.
