Description

Technical Field

[0001] This utility model relates to the field of flooring adhesive applicator technology, and in particular to a self-protecting glue box based on liquid level temperature control. Background Technology

[0002] A floor covering glue applicator is a mechanical device specifically designed to evenly apply glue to the back of floor coverings. The glue tank is one of the core components of the floor covering glue applicator, which holds the glue required for the application and ensures a continuous glue supply. If the temperature is too low, the glue will thicken, and if it is too high, it may decompose and become ineffective. At the same time, if the glue solidifies or is mixed with impurities, it may cause the glue pump to overload and the motor to burn out. Therefore, a self-protecting glue tank based on liquid level temperature control is required.

[0003] A self-protecting glue tank based on liquid level temperature control is an intelligent container that combines temperature control and liquid level management. It automatically adjusts the temperature near the liquid surface to prevent material performance changes due to high or low temperatures, thus avoiding equipment failure. In existing glue tank technologies, the inner liner is usually fixed with bolts, and the cured glue needs to be scraped off manually, sometimes even requiring disassembly of the entire machine, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a self-protecting glue box based on liquid level temperature control, which aims to improve the problem of bolt-fixed inner liner requiring manual scraping of cured glue or disassembly of the whole machine, which is cumbersome, time-consuming and labor-intensive.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-protecting plastic box based on liquid level temperature control, comprising a box body, an inner liner slidably connected to the inner wall of the box body, a connecting column slidably connected to the inside of the box body, a spring sleeved on the outer wall of the connecting column, the top end of the spring being fixedly connected to the outer wall of the connecting column, the bottom end of the spring being fixedly connected to the inside of the box body, a fixing column being fixedly connected to the outer wall of the connecting column, a limiting plate slidably connected to the outer wall of the fixing column, the outer wall of the limiting plate being slidably connected to the inside of the box body, a limiting column being fixedly connected to the outer wall of the limiting plate, the outer wall of the limiting column being slidably connected to the inside of the box body, the outer wall of the limiting column being slidably connected to the inner wall of the inner liner, a heating element being provided inside the box body, the heating element being located inside the inner liner, and an air supply assembly being provided on the outer wall of the box body.

[0006] Through the above technical solution: the sliding groove inside the limiting plate has a limiting effect on the fixed column. When the fixed column moves in the sliding groove of the limiting plate, it will drive the limiting plate to move through the sliding groove path. The limiting plate has a fixing effect on the limiting column. By sliding the limiting column inside the box, the inner liner can be clamped and limited, keeping the inner liner stable. The reset action of the spring can drive the connecting column to reset the limiting plate, thereby releasing the limiting column from restricting the inner liner, achieving the function of quick installation and disassembly. The inner liner can be disassembled for cleaning or replacement. The operation is simple and can adapt to the needs of handling different adhesives.

[0007] As a further description of the above technical solution: The gas supply assembly includes a gas box, the outer wall of which is fixedly connected to the outer wall of the housing, an air pump is fixedly connected inside the gas box, a pipe is fixedly connected to the output end of the air pump, a solenoid valve is fixedly connected to the outer wall of the pipe, and the outlet end of the pipe is located above the inner liner.

[0008] The above technical solution involves storing inert gas inside the gas chamber. By activating the air pump, the inert gas inside the gas chamber is transported through a pipeline to the inside of the inner liner to balance the environment, prevent the colloid from oxidizing, and better ensure the quality of the colloid.

[0009] As a further description of the above technical solution: The box body is rotatably connected to a box cover. The outer wall of the box cover is slidably connected to the outer wall of the connecting column. A sealing strip is fixedly connected to the outer wall of the box cover. The outer wall of the sealing strip is slidably connected to the inner wall of the box body. A magnetic block is magnetically connected to the outer wall of the box cover. The outer wall of the magnetic block is fixedly connected to the inside of the box body. The outer wall of the pipe is fixedly connected to the inside of the box cover. The outer wall of the solenoid valve is fixedly connected to the inside of the box cover.

[0010] The above technical solution achieves the opening and closing function through the lid, the magnetic block is fixed inside the box, and the lid can be firmly fixed to the upper surface of the box through the magnetic block. The sealing strip is fixed to the outer wall of the lid. When the lid is closed, the sealing strip will enhance the sealing between the lid and the inner liner to prevent oxygen from entering.

[0011] As a further description of the above technical solution: The heating element is electrically connected to a heating drive module, the heating drive module is electrically connected to a power management module, and the heating drive module is signal-connected to a main controller.

[0012] Through the above technical solution, the main controller can send control commands to the heating drive module, so that the heating drive module controls the heating element to adjust the heating temperature. By adjusting the heating temperature, the phenomenon of dry burning or aging of colloid residue can be avoided.

[0013] As a further description of the above technical solution: The power management module is electrically connected to the inert gas control module.

[0014] Through the above technical solution, the power management module can provide a stable power supply for the inert gas, ensuring the normal operation of the inert gas control module.

[0015] As a further description of the above technical solution: The output signal of the main controller is connected to the input of the inert gas control module, and the drive output of the inert gas control module is electrically connected to the control terminal of the gas pump.

[0016] Through the above technical solution: the main controller can receive the signal feedback from the inert gas control module, analyze it, and then send instructions to the inert gas control module, so that the inert gas control module can automatically adjust the gas flow according to the liquid level of the colloid, thereby avoiding overpressure in the empty box and maintaining the internal environment of the inner liner.

[0017] As a further description of the above technical solution: The signal input terminal of the main controller is connected to the data output terminal of the liquid level sensor module, and the output terminal of the main controller is electrically connected to the parameter setting terminal of the liquid level sensor module.

[0018] Through the above technical solution: the liquid level sensor module detects the level of the colloidal liquid and generates a signal. The main controller can receive the detection signal transmitted by the liquid level sensor module. The detection signal received by the main controller will send a control command to the heating drive module, which will further adjust the heating temperature of the heating element.

[0019] As a further description of the above technical solution: The output terminal of the main controller is electrically connected to the parameter setting terminal of the temperature protection module, and the alarm output terminal of the temperature protection module is electrically connected to the interrupt input terminal of the main controller.

[0020] Through the above technical solution, the temperature protection module can monitor the system temperature in real time, receive temperature data and feed back protection commands sent by the main controller. When the temperature exceeds the safe range, the protection mechanism is triggered by the main controller to prevent the equipment from overheating and being damaged, thus ensuring the safe operation of the equipment.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the movement of the connecting column causes the fixed column to slide inside the limiting plate and drive the limiting plate to move. The movement of the limiting plate will drive the limiting column to move and engage in the groove of the inner liner, achieving the clamping and limiting function, and realizing the effect of quick disassembly and installation, reducing the time for inner liner replacement and cleaning, and is simple to operate and adaptable to the requirements of handling different adhesives.

[0022] 2. In this utility model, the heating power is dynamically adjusted by liquid level feedback, and the temperature protection module is used for emergency power-off. This can prevent the adhesive from deteriorating or burning due to dry burning or overheating. When the liquid level is abnormal or the temperature exceeds the limit, the injection of inert gas is automatically triggered to replace the oxygen in the box and prevent the adhesive from oxidizing. The liquid level sensor module, heating drive module and inert gas control module achieve closed-loop safety control, which can better prevent overheating and maintain the stability of the adhesive.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a self-protecting plastic box based on liquid level temperature control, comprising a box body 1, an inner liner 2 slidably connected to the inner wall of the box body 1, a connecting column 3 slidably connected to the inside of the box body 1, a spring 4 sleeved on the outer wall of the connecting column 3, the top end of the spring 4 being fixedly connected to the outer wall of the connecting column 3, the bottom end of the spring 4 being fixedly connected to the inside of the box body 1, a fixing column 5 being fixedly connected to the outer wall of the connecting column 3, a limiting plate 6 slidably connected to the outer wall of the fixing column 5, the outer wall of the limiting plate 6 being slidably connected to the inside of the box body 1, a limiting column 7 being fixedly connected to the outer wall of the limiting plate 6, the outer wall of the limiting column 7 being slidably connected to the inside of the box body 1, the outer wall of the limiting column 7 being slidably connected to the inner wall of the inner liner 2, a heating element 8 being provided inside the box body 1, the heating element 8 being located inside the inner liner 2, and an air supply assembly 9 being provided on the outer wall of the box body 1. Specifically, the housing 1 supports the inner liner 2, supports and limits the offset of the connecting column 3, and supports the spring 4. When the connecting column 3 moves, it compresses the spring 4, and the spring 4, through its elasticity, can reset the connecting column 3. The connecting column 3 fixes the fixed column 5. The limiting plate 6 has a groove inside, which can limit the offset of the fixed column 5. When the fixed column 5 slides in the groove of the limiting plate 6, it will drive the limiting plate 6 to move. The housing 1 limits the offset of the limiting plate 6, so that the limiting plate 6 can only move left and right inside the housing 1. The limiting plate 6 fixes the limiting column 7, and the limiting column 7 is fixed by the limiting plate. The movement of column 6 is synchronized. The housing 1 has a limiting offset effect on the limiting post 7, so that the limiting post 7 can only move left and right inside the housing 1. The outer wall of the limiting post 7 is provided with an elastic element. One end of the elastic element is connected to the outer wall of the limiting post 7, and the other end is connected to the inside of the housing 1. The elastic element can generate a reset effect on the limiting post 7, helping the limiting post 7 to reset quickly. The limiting post 7 has a clamping and limiting effect on the inner liner 2. When the limiting post 7 slides into the groove on the outer wall of the inner liner 2, it will fix the inner liner 2 to ensure the stability of the inner liner 2. When the connecting post 3 and the limiting post 7 are reset, the inner liner 2 can be disassembled, so that the inner liner 2 can be quickly removed and cleaned to prevent glue blockage.

[0027] Reference Figure 1 and Figure 2 The air supply assembly 9 includes an air box 901. The outer wall of the air box 901 is fixedly connected to the outer wall of the box body 1. An air pump 902 is fixedly connected inside the air box 901. A pipe 903 is fixedly connected to the output end of the air pump 902. A solenoid valve 904 is fixedly connected to the outer wall of the pipe 903. The outlet end of the pipe 903 is located above the inner liner 2. Specifically, the housing 1 supports and fixes the air box 901, the air box 901 supports the air pump 902, and the pipe 903 is used to connect the air pump 902 and the solenoid valve 904 to form a gas transmission channel, ensuring that gas can reach the interior of the inner liner 2 from the air box 901. Inert gas can be transported to the interior of the inner liner 2 through the pipe 903 to control the environment inside the inner liner 2 and prevent the glue from being oxidized by oxygen. The air pump 902 can provide the power for gas transportation, extracting gas from the air box 901 and pressurizing it to the target location. The solenoid valve 904 can control the on / off of the gas in the pipe 903.

[0028] Reference Figure 1 and Figure 2 The box body 1 is rotatably connected to the box cover 10. The outer wall of the box cover 10 is slidably connected to the outer wall of the connecting column 3. The outer wall of the box cover 10 is fixedly connected to the sealing strip 11. The outer wall of the sealing strip 11 is slidably connected to the inner wall of the box body 1. The outer wall of the box cover 10 is magnetically connected to the magnetic block 12. The outer wall of the magnetic block 12 is fixedly connected to the inside of the box body 1. The outer wall of the pipe 903 is fixedly connected to the inside of the box cover 10. The outer wall of the solenoid valve 904 is fixedly connected to the inside of the box cover 10. Specifically, the box body 1 supports the box lid 10, and the box lid 10 can be opened and closed by vibration. The box body 1 fixes the magnetic block 12, and the magnetic force of the magnetic block 12 can firmly attach the box lid 10 to the box body 1. The box lid 10 fixes the sealing strip 11, and the sealing strip 11 can enhance the sealing between the box lid 10 and the inner liner 2. The sealing strip 11 can prevent gas leakage from the inner liner 2. When the box lid 10 is closed, the box lid 10 will squeeze the connecting post 3, which will further cause the connecting post 3 to drive the limiting post 7 to clamp and limit the inner liner 2.

[0029] Reference Figure 4 The heating element 8 is electrically connected to a heating drive module, the heating drive module is electrically connected to a power management module, and the heating drive module is signal connected to a main controller. Specifically, the power supply can provide power to the heating drive module and the main controller. The main controller can send control commands to the heating control module and receive temperature feedback signals. If the temperature deviates from the set value, the main controller will dynamically adjust the drive signal and send commands to the heating drive module. The heating module will control the on / off state and power adjustment of the heating element 8 through the commands sent by the main controller, so that the heating element 8 can adjust the temperature when heating the colloid inside the inner liner 2.

[0030] Reference Figure 4 The power management module is electrically connected to the inert gas control module; the output signal of the main controller is connected to the input of the inert gas control module, and the drive output of the inert gas control module is electrically connected to the control terminal of the gas pump 902. Specifically, the power management module can provide a stable power supply to the inert gas control module. When the oxygen concentration inside the inner liner 2 exceeds the safety threshold, the main controller will generate a control signal and send it to the inert gas control module. The inert gas control module will then send a gas supply command to the air pump 902. The start of the air pump 902 will inject inert gas into the inner liner 2 to dilute the oxygen concentration. When the oxygen concentration drops to the safety threshold, the main controller will stop the gas supply command. Through the supply of inert gas, the quality of the colloid inside the inner liner 2 can be effectively guaranteed.

[0031] Reference Figure 4 The signal input terminal of the main controller is connected to the data output terminal of the liquid level sensor module, and the output terminal of the main controller is electrically connected to the parameter setting terminal of the liquid level sensor module; the output terminal of the main controller is electrically connected to the parameter setting terminal of the temperature protection module, and the alarm output terminal of the temperature protection module is electrically connected to the interrupt input terminal of the main controller. Specifically, the liquid level sensor module can detect the height of the colloid. When the colloid is sufficient, it sends a heating signal to the heating drive module through the main controller. When the colloid height is low, the liquid level sensor module converts the data into an electrical signal and transmits it to the main controller. The main controller analyzes and processes the received signal and transmits a feedback signal to the liquid level sensor module through its output terminal. At the same time, the main controller sends a signal to the heating drive module, which controls the heating temperature of the heating element 8 to prevent dry burning or aging and deterioration of residual colloid on the heating element 8. The temperature protection module can detect the temperature of the colloid. When the temperature is too high, it sends a signal to the main controller, which then inputs a control command to the heating drive module to reduce the heating temperature.

[0032] Working principle: When the plastic box is needed, the inner liner 2 is placed inside the box body 1, and then the lid 10 is closed. The lid 10 will adhere to the magnetic block 12 through magnetic action. At the same time, the sealing strip 11 ensures a tight fit between the lid 10 and the box body 1, improving the sealing performance. After the lid 10 is closed, it will press against the connecting post 3. The connecting post 3 will slide inside the box body 1 due to the pressure. When the connecting post 3 slides, it will cause the fixing post 5 to slide against the inner wall of the limiting plate 6, and drive the limiting plate 6 to move inside the box body 1. When the limiting plate 6 moves... The limiting post 7 will move inside the box 1. Further, the limiting post 7 will move into the groove on the outer wall of the inner liner 2, which will limit the displacement of the inner liner 2 and prevent it from shifting or moving. When the inner liner 2 needs to be cleaned, the box cover 10 is opened. At this time, the box cover 10 will no longer squeeze the connecting post 3, and the connecting post 3 will no longer squeeze the spring 4. The spring 4 will drive the connecting post 3 to move upward, which will further cause the limiting plate 6 to drive the limiting post 7 to disengage from the groove of the inner liner 2, thereby releasing the restriction on the inner liner 2 and achieving the effect of quick disassembly. When applying adhesive to the floor covering, the adhesive needs to be heated. A liquid level sensor module monitors the adhesive level in real time. When the liquid level sensor detects that the level is lower than the heating element 8, it generates an electrical signal and transmits it to the main controller. The main controller then interprets the signal and sends a control command to the heating drive module, causing it to adjust the temperature of the heating element 8, reducing the heating temperature and preventing residual adhesive from aging and deteriorating on the surface of the heating element 8. After replacing the inner liner 2 and the adhesive, the inert gas control module detects the oxygen content inside the inner liner 2 and transmits the detection signal to the main controller. Based on the control command from the main controller, the inert gas control module starts the air pump 902. The gas inside the gas chamber 901 is transported to the inner liner 2 through pipe 903, where the inert gas neutralizes the oxygen content inside the inner liner 2, preventing the colloid from oxidizing. The temperature protection module monitors the glue temperature in real time. When the temperature exceeds the set threshold, it will trigger the protection mechanism in a timely manner by transmitting and receiving feedback signals to the main controller to prevent the equipment from overheating and ensuring the safe operation of the system. This device can not only quickly disassemble the inner liner 2 to prevent residual glue from curing and clogging the pipes and contaminating the new glue, but also adapt to the needs of handling different glues and improve work efficiency. At the same time, it can also dynamically adjust the heating power through liquid level feedback. Combined with the emergency power cut-off of the temperature protection module, it can prevent the glue from deteriorating or burning due to dry burning or overheating, and can better prevent overheating and maintain the stability of the glue.
