[0002] Anti-slip structural layer adhesive is a two-component (usually component A and component B) adhesive, widely used in rubber-tired tram systems, industrial flooring, and anti-slip pavement.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0042] Currently, the sampling and mixing of special adhesive for anti-slip structural layers mainly adopts the sampling and mixing of a dispensing machine. The cylinder piston of the dispensing machine pressurizes two glue storage tanks. The two-component adhesive flows out of the glue storage tanks along the pipes above the glue storage tanks under the pressure of the piston cylinder. The pipes above the glue storage tanks converge and flow into the mixer for mixing. After being mixed evenly, it is used.

[0043] However, because the viscosity of adhesive varies greatly at different temperatures, and the viscosity of adhesive is high at low temperatures, it is difficult for the dispensing machine to mix different adhesives evenly, which makes it difficult for the dispensing machine to operate around the clock.

[0044] In view of the above problems, this application provides a glue mixing device. Before mixing, the glue to be mixed can be heated by a heating element to improve the mixing effect and keep the mixed glue at a suitable temperature. This allows the glue to maintain a suitable viscosity even when facing low temperature conditions, so that the glue mixing device can fully mix different glues at low temperatures. Thus, the glue mixing device can adapt to all-weather operation.

[0045] The specific implementation of the adhesive dispensing device provided in this application will be described in detail below with reference to the accompanying drawings.

[0046] Reference Figures 1 to 4 As shown, the adhesive dispensing device provided in this application embodiment includes a first container 100, a heating element 200 and an adhesive mixing mechanism 300. The first container 100 has at least two receiving cavities 110, and the different receiving cavities 110 are configured to contain different adhesives. The heating element 200 is configured to heat the adhesive in the receiving cavity 110.

[0047] The mixing mechanism 300 has a mixing chamber, which has a first glue outlet 311 and at least two first glue inlets 312. The first glue inlets 312 correspond one-to-one with the receiving chamber 110 and are connected to each other.

[0048] The adhesive mixing device provided in this application embodiment is used to heat the adhesive, quantitatively mix different adhesives, and then obtain the finished adhesive. The finished adhesive can be coated on the workpiece to form an anti-slip structural layer. For example, the finished adhesive can be coated on tram tracks.

[0049] In this embodiment of the application, since the first container 100 has different receiving cavities 110, the different receiving cavities 110 can hold different adhesives. For example, the first container 100 has two receiving cavities 110, one receiving cavity 110 is used to hold adhesive A, and the other receiving cavity 110 is used to hold adhesive B. After adhesive A and adhesive B are quantitatively proportioned and mixed by the adhesive dispensing device, the finished adhesive can be obtained.

[0050] Since the mixing chamber has a first glue outlet 311 and at least two first glue inlets 312, different glues enter the mixing chamber from the corresponding first glue inlets 312 according to the flow direction of the glue. After being mixed in the mixing chamber, they flow out of the mixing chamber from the first glue outlet 311. Therefore, the number of first glue inlets 312 is set in correspondence with the number of receiving cavities 110, so that the glue from different receiving cavities 110 flows into the mixing chamber from the corresponding first glue inlets 312.

[0051] For example, when the first container 100 has two receiving cavities 110, one receiving cavity 110 is used to receive adhesive A and the other receiving cavity 110 is used to receive adhesive B. Correspondingly, the mixing cavity has two first inlets 312. Adhesive A enters the mixing cavity from one first inlet 312 and adhesive B enters the mixing cavity from the other first inlet 312. In this way, adhesive A and adhesive B can be mixed evenly in the mixing cavity, and the finished adhesive is then applied to the workpiece.

[0052] It should be noted that, compared with the prior art, the glue dispensing device in this embodiment is equipped with a heating element 200, which can heat the glue in each receiving cavity 110, thereby reducing the viscosity of the glue and improving the fluidity of the glue at low temperatures. This makes it easier to mix and proportion different glues, thereby improving the working performance of the glue dispensing device at low temperatures.

[0053] The heating element 200 can heat the first container 100 and then transfer the heat to the adhesive through the first container 100. For example, the heating element 200 can be disposed outside the first container 100 and in contact with the first container 100. Alternatively, the heating element 200 can also directly heat the adhesive. For example, the heating element 200 can be disposed inside the receiving cavity 110 and in contact with the adhesive.

[0054] The adhesive dispensing device provided in this application includes a first container 100, a heating element 200, and a mixing mechanism 300. The first container 100 includes a receiving cavity 110, and the mixing mechanism 300 includes a mixing chamber, which includes a first outlet 311 and a first inlet 312. The receiving cavity 110 is used to hold different adhesives, and the mixing chamber is used to mix different adhesives to obtain a finished adhesive. The first inlet 312 connects the receiving cavity 110 and the mixing chamber, allowing different adhesives to enter the mixing chamber from their respective inlets 312. The first outlet 311 allows the finished adhesive to flow out of the mixing chamber. The heating element 200 heats the various adhesives before mixing to reduce their viscosity and improve their flowability. This facilitates thorough and uniform mixing of different adhesives, and the mixed finished adhesive maintains a suitable temperature, which is beneficial for coating the workpiece with the finished adhesive. Therefore, the glue dispensing device provided in this application embodiment has good working performance even in low-temperature conditions, thus enabling the glue dispensing device to adapt to all-weather operation.

[0055] Reference Figures 1 to 3As shown, in one possible implementation, the adhesive dispensing device provided in this application embodiment further includes a second container 400, and the heating element 200 is connected to one of the first container 100 and the second container 400. The second container 400 has a heating chamber 410, at least a portion of the heating element 200 is located in the heating chamber 410, and at least a portion of the receiving cavity 110 is located in the heating chamber 410.

[0056] For example, the heating element 200 is disposed in the heating chamber 410 and is connected to the first container 100. The heat generated by the heating element 200 can be radiated to the first container 100. The cavity wall of the heating chamber 410 can block and reflect the heat, thereby reducing heat loss. The heat is conducted to the glue through the first container 100, thereby heating the glue in different accommodating cavities 110.

[0057] Alternatively, the heating element 200 is disposed in the heating chamber 410 and connected to the second container 400. Liquids such as water can be added to the heating chamber 410. The heating element 200 can heat the water, thereby heating the glue through the water. This is the water bath method. The water bath method can uniformly heat the glue in the container 110, thereby improving the heating effect of the glue.

[0058] Reference Figure 1 , Figure 2 As shown, in some embodiments, the adhesive dispensing device of this application further includes a control component 500, which is electrically connected to the heating element 200 and configured to control the heating power of the heating element 200.

[0059] In this way, the control component 500 can control the heating power of the heating element 200 according to the current temperature of the heating element 200, or the control component 500 can control the heating power of the heating element 200 according to the current temperature of the adhesive, or the control component 500 can control the heating power of the heating element 200 according to the current temperature of the water medium, so that the adhesive is heated to between 25°C and 35°C. Within this temperature range, the viscosity of the adhesive is low, which is beneficial to the mixing of different adhesives.

[0060] Reference Figure 3 As shown, in one possible implementation, the adhesive dispensing device of this application further includes a temperature detection component 600, which is electrically connected to the control component 500, and the detection end of the temperature detection component 600 extends into at least one of the heating chamber 410 and the receiving chamber 110.

[0061] For example, the temperature detection component 600 may include an adhesive temperature detection component 610, the detection end of which extends into the receiving cavity 110 to detect the current temperature of the adhesive. If the current temperature of the adhesive reaches a first preset temperature, the control component 500 may control the heating element 200 to stop heating.

[0062] For example, the temperature detection component 600 may include a water temperature detection component 620, the detection end of which extends into the heating chamber 410 to detect the current temperature of the water medium. If the current temperature of the water medium reaches a second preset temperature, the control component 500 may control the heating element 200 to stop heating.

[0063] For example, the temperature detection component 600 may include an adhesive temperature detection component 610 and a water temperature detection component 620. The detection end of the adhesive temperature detection component 610 extends into the receiving cavity 110 to detect the current temperature of the adhesive. The detection end of the water temperature detection component 620 extends into the heating cavity 410 to detect the current temperature of the water medium. The control component 500 can control the temperature of the water medium according to the temperature of the adhesive, thereby maintaining the temperature of the adhesive and thus maintaining the viscosity of the adhesive.

[0064] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, in one possible implementation, the adhesive dispensing device of this application further includes a dispensing mechanism 700, which includes at least two flow control pumps 710 and at least two pipes 720. The flow control pumps 710 and pipes 720 are arranged in a one-to-one correspondence, and the pipes 720 are arranged in a one-to-one correspondence with the receiving cavity 110.

[0065] Each pipe 720 has a second outlet 721 and a second inlet 722. A flow control pump 710 is connected between the second outlet 721 and the second inlet 722. The second inlet 722 is connected to the receiving cavity 110, and the second outlet 721 is connected to the first inlet 312.

[0066] It is understandable that different adhesives need to be quantitatively proportioned before mixing so that the performance of the mixed adhesive meets the requirements. Therefore, after the adhesive is heated in the receiving cavity 110, it can enter the pipeline 720 under the driving force of the flow control pump 710. The flow control pump 710 can control the flow rate of the adhesive, thereby regulating the quality of the adhesive entering the mixing cavity so that different adhesives can be mixed according to the formula ratio.

[0067] Reference Figure 5 , Figure 6 As shown, in some embodiments, the mixing mechanism 700 further includes at least one drive motor 730, and at least two flow control pumps 710 are connected to the drive motor 730. With this configuration, the drive motor 730 can drive the flow control pumps 710 to move, thereby allowing the flow control pumps 710 to control the quality of the adhesive entering the mixing chamber by controlling the flow rate of the adhesive.

[0068] In this configuration, there can be one drive motor 730, which drives multiple flow control pumps 710. In this case, the drive motor 730 can be a variable frequency motor. Alternatively, there can be multiple drive motors 730, in which case servo motors can be used. Servo motors have a fast response speed. Multiple drive motors 730 are connected one-to-one with multiple flow control pumps 710, so that each drive motor 730 drives the flow control pump 710 connected to it. This allows for precise control of the flow rate of different adhesives, thereby improving the mixing accuracy of the mixing mechanism 700 and adapting to different mixing ranges of adhesives, thus broadening its application range.

[0069] Reference Figure 5 As shown, in one possible implementation, the proportioning mechanism 700 further includes a transmission assembly 740, through which at least two flow control pumps 710 are connected to the same drive motor 730.

[0070] In other words, multiple flow control pumps 710 share a single drive motor 730, and the power of the drive motor 730 can be transmitted to the multiple flow control pumps 710 through the transmission assembly 740, thereby driving each flow control pump 710 to rotate.

[0071] Reference Figure 5 As shown, in one possible implementation, the transmission assembly 740 includes a first transmission member 741 and a second transmission member 742, a drive motor 730 is connected to the first transmission member 741, the second transmission member 742 is connected to the first transmission member 741, and at least two flow control pumps 710 are connected to the second transmission member 742.

[0072] With this configuration, the drive motor 730 can transmit power to the first transmission component 741, which in turn transmits power to the second transmission component 742. The second transmission component 742 then transmits power to multiple flow control pumps 710, thereby driving the multiple flow control pumps 710 to move and regulate the flow rate of the adhesive.

[0073] In some embodiments, the flow control pump 710 includes a pump housing and a gear set. The pump housing has a chamber, the gear set is located in the chamber, and a drive motor 730 is connected to the gear set to drive the gear set to rotate.

[0074] In this way, the drive motor 730 can drive the gear set to rotate, and then the glue can be sucked in and discharged through the meshing of the gear set. In specific implementation, the flow rate of the glue can be controlled by controlling the speed of the gear set, thereby realizing the quantitative dispensing of different glues.

[0075] Reference Figure 5 , Figure 6As shown, in one possible implementation, the proportioning mechanism 700 further includes at least two flow detection components 750, which are respectively disposed in the pipeline 720, and the flow detection components 750 are located between the second dispensing port 721 and the flow control pump 710.

[0076] Thus, the flow detection component 750 can detect the flow rate of its corresponding pipe 720, and the flow detection component 750 is electrically connected to the control component 500, thereby feeding the flow information back to the control component 500. The control component 500 can calculate the current flow rate of the adhesive. Based on the relationship between the preset flow rate and the current flow rate, the control component 500 can determine whether it is necessary to adjust the speed of the drive motor 730, so that the flow rate of the adhesive is consistent with the preset flow rate, thereby improving the accuracy of the adhesive mixing ratio.

[0077] Understandably, when the temperature of the adhesive does not meet the requirements, the control component 500 can control the drive motor 730 to stop and adjust the heating power of the heating element 200 until the temperature of the adhesive meets the requirements. Then, the control component 500 can control the drive motor 730 to start, thereby delivering adhesive with the required temperature to the mixing chamber.

[0078] Reference Figure 4 As shown, in some embodiments, the mixing mechanism 700 further includes a first control valve 760, which is located at one of the second glue outlet 721 and the first glue inlet 312 and is configured to control the on / off state between the mixing chamber and the pipe 720.

[0079] Thus, before mixing begins, the first control valve 760 can be opened to keep the pipe 720 and the mixing chamber connected, thereby facilitating the continuous entry of adhesive into the mixing chamber. Once sufficient adhesive has entered the mixing chamber, the first control valve 760 can be closed to disconnect the mixing chamber from the pipe 720, thereby preventing adhesive in the pipe 720 from continuing to flow into the mixing chamber. Furthermore, during mixing, air can be prevented from entering the mixing chamber and causing air bubbles.

[0080] Reference Figure 5 As shown, in some embodiments, the dispensing mechanism 700 further includes a second control valve 770, which is located at the second dispensing port 721 and configured to regulate the pressure state of the pipeline 720. Therefore, when the pressure inside the pipeline 720 is high, the second control valve 770 can be opened to release the pressure, thereby ensuring the safe operation of the dispensing device.

[0081] The proportioning mechanism 700 may also include a pressure detection component 780, which is installed on the pipeline 720 and used to detect the pressure status of the pipeline 720. In this way, when the pressure is too high, the pressure detection component 780 can feed back the pressure information to the control component 500, and the control component 500 controls the second control valve 770 to open and relieve pressure.

[0082] Reference Figure 4 As shown, in some embodiments, the mixing mechanism 300 includes a mixing tube seat 310 and a mixing tube 320. The mixing chamber is located in the mixing tube seat 310, and the mixing tube 320 is connected to a first dispensing port 311. The end of the mixing tube 320 away from the mixing tube seat 310 has a third dispensing port 321, and the diameter of the third dispensing port 321 gradually decreases from the end near the mixing tube seat 310 to the end away from the mixing tube seat 310.

[0083] In this way, the glue is split into many fine streams in the mixing tube 320 and then merged and intertwined before finally flowing out from the third glue outlet 321, thus achieving full mixing of the finished glue. During this process, the glue does not need to be mixed by stirring, which can prevent the glue from being over-stirred and causing heat generation.

[0084] Because the third dispensing port 321 is conical, and the large-diameter end of the third dispensing port 321 is located close to the mixing chamber, while the small-diameter end of the third dispensing port 321 is located far away from the mixing chamber, the third dispensing port 321 can create a certain resistance to the glue, ensuring that the glue forms a full-pipe flow after mixing, thereby preventing air from entering the mixing tube 320 and thus preventing the finished glue from generating air bubbles.

[0085] Reference Figure 4 As shown, in some embodiments, the mixing chamber also has an air inlet 313, which is connected to an air source such as a compressor.

[0086] In this way, after the glue mixing device completes the glue mixing work, the air source can provide compressed air to the glue mixing chamber, and then use the compressed air to clean the glue adhering to the chamber wall and the wall of the mixing tube 320. Subsequently, the mixing tube 320 can be removed from the mixing tube seat 310 and the mixing tube 320 can be cleaned.

[0087] Reference Figure 3 As shown, in some embodiments, the adhesive dispensing device further includes a liquid level detection component 800, which is located at the bottom of the receiving cavity 110. When the liquid level of the adhesive is lower than the preset liquid level, the liquid level detection component 800 feeds back the liquid level information to the control component 500. The control component 500 issues an alarm signal and controls the drive motor 730 to stop. The alarm signal includes one or both of an audible and visual alarm and a buzzer alarm.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
