Description

Technical Field

[0001] This invention relates to the field of coating production and processing technology, specifically to a dual-filter switching adhesive supply system with constant temperature control. Background Technology

[0002] In the coating production and processing field, the stability and cleanliness of the adhesive supply system directly determine the quality of the final coated product. To avoid foreign matter and impurities in the adhesive causing defects such as crystal points, scratches, and missed coatings in the coated product, existing coating production lines usually install a filter device in the adhesive supply pipeline to filter the adhesive and remove impurity particles.

[0003] However, during long-term use, the filter element of the filtration device will gradually become clogged as impurities accumulate, leading to increased pressure in the liquid supply line, unstable glue flow, and the need for shutdown for maintenance. This affects the normal operation of coating production. Furthermore, during the replacement of clogged filter elements, a large amount of outside air enters the empty filter cartridge. When the liquid supply line is reconnected after replacement, the air mixed in with the filter cartridge will enter the liquid supply system along with the glue, resulting in a large number of air bubbles in the subsequently output glue. During coating, this will form bubble defects on the surface of the finished product, requiring additional manual defoaming and bubble removal processes. This not only increases the complexity of the production process but also wastes glue, further reduces production efficiency, and may even affect the quality of the final product due to incomplete defoaming.

[0004] On the other hand, the viscosity and flowability of adhesives are directly related to temperature. Different types of coating adhesives have high requirements for temperature stability during the adhesive supply process. Temperature fluctuations can cause changes in adhesive viscosity, leading to problems such as fluctuations in adhesive supply flow and uneven coating thickness. Currently, most dual-filter switching adhesive supply systems only focus on the function of filter switching and do not have a precise constant temperature control module. They cannot stably regulate the adhesive temperature in the filter pipeline and adhesive supply process. In production scenarios with large ambient temperature variations, adhesive temperature fluctuations can easily affect the coating quality and make it difficult to meet the process requirements of high-precision coating production.

[0005] Therefore, in order to improve the stability of the coating adhesive supply system and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the existing temperature-controlled dual-filter switching adhesive supply system and application method. Summary of the Invention

[0006] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a temperature-controlled dual-filter switching adhesive supply system, primarily to solve the problem of external gas being introduced when replacing the filter mechanism in existing technologies.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A temperature-controlled dual-filter switching glue supply system includes a support frame, a fixing frame, and a control component. The fixing frame is equipped with a dual-filter component, which includes two filter cartridges of the same specifications. Each filter cartridge includes a glue inlet pipe and a glue outlet pipe. The two glue inlet pipes are connected to the same solenoid three-way valve A through pipes, and the two glue outlet pipes are connected to the same solenoid three-way valve B through pipes. The filter cartridge is threadedly connected to the filter housing. The filter cartridge includes a housing and a filter element. There is an adhesive passage chamber between the filter element and the housing. A sealing film is pasted on the top of the filter element. The diameter of the sealing film is the inner diameter of the filter cartridge housing. An inner sealing ring is provided at the edge of the sealing film. The inner sealing ring is sealed and adhered to the inner wall of the filter cartridge housing. A vacuum valve is provided on the outer wall of the filter cartridge housing. A rotating disk is inserted inside the filter cartridge shell. The rotating disk has a through hole and a transmission rod is fixed on the rotating disk. The top of the transmission rod passes through the filter cartridge shell, and a sealing block is fixed below the transmission rod. The sealing block has a bullet-shaped structure and multiple arc-shaped glue outlet channels. A sealing plate is fixed inside the filter cartridge shell. The sealing plate is installed below the rotating disk. A first puncture cover is welded onto the sealing plate. The sealing block can fit seamlessly with the first puncture cover. The height of the first puncture hood is one-third to one-half of the depth of the thread at the top of the filter cartridge; The first puncture cover has multiple first glue inlet holes, and the glue outlet channel can be aligned with the first glue inlet holes; a spike is provided at the bottom of the first puncture cover, and a ridge is obliquely provided on the spike. The septum is provided with a second puncture cover, which can be aligned and connected with the through hole. The second puncture cover has a second glue inlet hole and a blade at the bottom.

[0008] (III) Beneficial Effects Compared with the prior art, the present invention provides a temperature-controlled dual-filter switching adhesive supply system, which has the following advantages: 1. By designing the dimensions of the sealing membrane at the top of the filter cartridge, the inner sealing ring, the vacuum valve, the rotating disc, the sealing block, the first sealing gasket, the first puncture cover, and the second puncture cover, the filter cartridge maintains a vacuum state throughout the filter cartridge replacement process. The glue inlet and outlet channels are completely sealed off by the rotating disc and the sealing block, preventing outside air from entering the glue supply system. When installing a new filter cartridge, the first sealing gasket first completes the mechanical seal, and then the puncture cover automatically punctures the sealing membrane to open the flow channel. The entire replacement process requires no manual intervention for venting, fundamentally eliminating the problem of air mixing into the glue during filter cartridge replacement in existing technologies. This avoids the generation of bubble defects on the surface of the finished coated product, eliminating the need for additional defoaming and degassing processes, and significantly reducing production complexity and glue consumption.

[0009] 2. Through the coordinated setup of the heat-conducting fan, heating pipes, insulation jacket A, insulation jacket B, and insulation cover, the heat from the settling heating tank and heater is synchronously delivered to the glue inlet pipe, glue outlet pipe, glue delivery pipe, and the outer wall of the filter cartridge shell, forming a closed-loop constant temperature control network covering the entire glue supply process. Combined with dual temperature control from a PID temperature controller and a temperature controller, the glue temperature is kept constant within the set range, effectively suppressing the impact of ambient temperature fluctuations on glue viscosity and ensuring stable glue supply flow and uniform coating thickness. Simultaneously, during filter switching or filter cartridge maintenance, the insulation system continuously heats and insulates the glue remaining in the pipeline, preventing the glue from solidifying and clogging the pipeline due to stagnation and cooling. This achieves truly uninterrupted constant temperature glue supply, meeting the stringent temperature stability requirements of high-precision coating processes.

[0010] 3. With the dual-filtration channel configuration of electromagnetic three-way valves A and B, combined with real-time monitoring by the differential pressure sensor, when the filter element becomes clogged and the differential pressure exceeds the threshold, the PLC control system can automatically switch to the backup filter channel within 0.5 seconds and simultaneously trigger an audible and visual alarm, achieving online switching without stopping the system and avoiding glue supply interruptions or flow fluctuations caused by filter element clogging. At the same time, the dual-frequency standing wave transducer installed on the glue supply pipeline can radiate ultrasonic waves during glue delivery, using the high-frequency shear flow effect to dislodge tiny air bubbles in the glue and perform online self-cleaning of the inner wall of the glue tube, preventing glue deposition and scaling, effectively extending the service life of the filter element, reducing maintenance frequency, and comprehensively improving the continuous operation stability and automation level of the glue supply system.

[0011] 4. Through the dual-position design of the adjustment handle, the convenient disassembly and assembly structure of the knob at the bottom of the filter cartridge, and the multi-layer sealing gasket combination configuration of the first sealing gasket, the second sealing gasket, and the sealing ring, a mechanically interlocked state switching mechanism is formed; the adjustment handle has a damping positioning function when rotating, which can effectively prevent position drift caused by misoperation or vibration, and ensure the fitting accuracy between the sealing block and the puncture cover; each sealing interface maintains reliable sealing under different working conditions such as filter cartridge installation, flow channel switching, and system operation, achieving leak-free operation, reducing the risk of glue spillage and environmental pollution, while simplifying the maintenance operation process for operators and improving the safety and maintenance efficiency of equipment operation.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Reference Figures 1-9 A temperature-controlled dual-filter switching adhesive supply system includes a support frame 1, a fixing frame 2, and a control component. The control component is a PLC controller 33. An LED warning light 34 is installed on the top of the housing of the PLC controller 33. The LED warning light 34 is electrically connected to the PLC controller 33. The settling heating tank 24 and the feed pump 26 are fixed to the support frame 1 by bolts; The feed pump 26 is equipped with a glue injection pipe 27 that connects to an external feeding system at its inlet. The outlet of the feed pump 26 is sealed to the inlet of the settling heating tank 24 through a glue supply pipe, and an external transducer 2401 is installed on the glue supply pipe. A cylindrical heater 25 is bolted to the outside of the settling heating tank 24. The heater 25 can heat the outer wall of the settling heating tank 24. The heater 25 includes a PID temperature controller to ensure that the temperature inside the settling heating tank 24 is constant within the set range. Heater 25 is equipped with heat conduction fan 29, and heat supply pipe 32 is provided on the air outlet of heat conduction fan 29 with sealing sleeve. like Figure 2 As shown, a dual filter assembly is installed on the mounting bracket 2; The dual filtration assembly consists of two identical filter cartridge housings 4; Two mounting brackets 3 are fixed to the fixed frame 2 by bolts. Two filter cartridge shells 4 are respectively fixed to the two mounting brackets 3 by bolts. Each of the two filter cartridge shells 4 includes an inlet pipe 9 and an outlet pipe 17. Two glue inlet pipes 9 are connected to the same electromagnetic three-way valve A 22 through pipes. The electromagnetic three-way valve A 22 is sealed to the discharge port of the settling heating tank 24 through pipes, and an external transducer 2401 is installed on the pipes. Both external transducers 2401 are dual-frequency standing wave transducers. They can drive piezoelectric ceramic materials (such as PZT) to generate mechanical vibration by applying a high-frequency electrical signal, thereby radiating low-frequency or high-frequency sound waves, i.e. ultrasound, into the medium, which causes the air bubbles in the glue to be shaken off. At the same time, it can also achieve online self-cleaning and prevent glue deposition. The frequency combination of the dual-frequency standing wave transducer can be selected as 15kHz and 40kHz. The flow path can be changed by using the solenoid three-way valve A 22, which determines which filter group the glue flows to. Two glue outlet pipes 17 are connected to the same solenoid three-way valve B 23 through a pipe. The solenoid three-way valve B 23 is connected to a glue delivery pipe 28, and a heat insulation jacket B 31 is installed on the glue delivery pipe 28. The flow path can be changed by using the electromagnetic three-way valve B 23, which determines which group of adhesive flows out from. Both the inlet pipe 9 and the outlet pipe 17 are sealed with heat insulation jackets A 30, and multiple heat insulation jackets A 30 and heat insulation jackets B 31 are sealed to the heating pipe 32 of the heat transfer fan 29 through pipes. The heat transfer fan 29 and the heating pipe 32 transfer the heat from the heater 25 to the insulation jacket A 30 and the insulation jacket B 31, which ensures that when switching or repairing the filter system, the glue in the pipe will not solidify inside the pipe because there is no subsequent glue to squeeze it out. like Figure 3 and Figure 4 As shown, the filter housing 4 includes a differential pressure sensor 20 and a pressure gauge 21; A heat insulation cover 19 is provided on the outer circumferential wall of the filter cartridge shell 4. The heat insulation cover 19 includes an electric heating belt 1902 inside. A temperature controller 1903 is fixed to the outer wall of the heat insulation cover 19 by bolts. The electric heating belt 1902 is electrically connected to the temperature controller 1903. A heat insulation pad 1901 is provided below the heat insulation cover 19. The heat insulation pad 1901 is used to seal the bottom of the filter cartridge shell 4. The filter cartridge shell 4 is internally threaded with a filter cartridge 5, and the filter cartridge shell 4 and the filter cartridge 5 are sealed together. A knob 502 is provided at the bottom of the filter cartridge 5, and the knob 502 can be held by hand to facilitate the installation of the filter cartridge 5. like Figure 5 As shown, the filter cartridge 5 includes a shell and a filter element 503. The filter element 503 has a cylindrical structure. There is an adhesive passage chamber between the filter element 503 and the shell. A sealing membrane 8 is pasted on the top of the filter element 503. The sealing membrane 8 seals the top of the filter element 503. The diameter of the sealing membrane 8 is the inner diameter of the shell of the filter cartridge 5. An inner sealing ring 7 is provided at the edge of the sealing membrane 8. The inner sealing ring 7 is sealed and bonded to the top of the inner wall of the shell of the filter cartridge 5. The sealing membrane 8, the inner sealing ring 7 and the highest point of the shell are flush. The sealing membrane 8 is made of fluororubber or nitrile rubber, which can stably maintain the high vacuum environment without deformation; The outer wall of the filter cartridge 5 is equipped with a vacuum valve 501, which removes air from the filter cartridge 5, making it a vacuum product.

[0016] like Figure 6 As shown, the top of the filter cartridge shell 4 is provided with an adhesive inlet channel 401 and an adhesive outlet channel 402. The adhesive inlet channel 401 is connected to the adhesive inlet pipe 9, and the adhesive inlet channel 401 is located directly above the middle channel of the filter element 503. The glue outlet channel 402 is connected to the glue outlet pipe 17, and the glue outlet channel 402 is located directly above the glue passage chamber of the filter element 503 and the filter cartridge 5. The two sensing heads of the differential pressure sensor 20 are located in the glue inlet channel 401 and the glue outlet channel 402. They are used to detect the pressure in the glue inlet channel 401 and the glue outlet channel 402. If the pressure difference exceeds the predetermined range, it indicates that the glue inlet and outlet speeds and viscosity are inconsistent, and there is a material supply problem. A rotating disk 14 is inserted inside the filter cartridge shell 4. A transmission rod 12 is fixed on the rotating disk 14. The top end of the transmission rod 12 passes through the filter cartridge shell 4 and is fixed with an adjustment handle 13. The adjustment handle 13 has two positions, namely the open position and the closed position. The rotating disk 14 can be rotated by adjusting the handle 13. The adjustment handle 13 has damping when rotating and cannot be shaken at will. A sealing plate 1401 is fixed inside the filter cartridge shell 4. The sealing plate 1401 is located directly below the rotating disk 14. Multiple second sealing gaskets 15 are provided on the upper and lower surfaces of the rotating disk 14. The second sealing gaskets 15 are in contact with the inner wall of the top of the filter cartridge shell 4 and the upper surface of the sealing plate 1401, respectively. A first sealing gasket 6 is provided on the outer wall of the top of the filter cartridge 5. When the filter cartridge 5 is installed, the first sealing gasket 6 can contact the inner wall of the filter cartridge shell 4, thereby ensuring the sealing of the connection between the filter cartridge 5, the filter cartridge shell 4, and the sealing plate 1401. A sealing block 11 is fixed below the transmission rod 12. The sealing block 11 has multiple glue outlet channels 1101 and a sealing ring 1102 is provided on the outer wall of the sealing block 11. A first puncture cover 10 is welded onto the septum 1401, and the sealing block 11 can fit seamlessly with the first puncture cover 10. The height of the first puncture cover 10 is one-third to one-half of the thread depth at the top of the filter cartridge 5, so as to prevent the first puncture cover 10 from puncturing the sealing membrane 8 at the first moment when the filter cartridge 5 is installed, thereby eliminating the possibility that the sealing membrane 8 will be punctured before the first sealing gasket 6 and the inner wall of the filter cartridge shell 4 are sealed. The maximum outer diameter of the first puncture cover 10 does not exceed 70%-80% of the diameter of the internal cylindrical channel of the filter element 503, so as to avoid the situation where the first puncture cover 10 cannot be inserted and no space is reserved for glue injection, which ultimately prevents the glue from being injected quickly. The first puncture cover 10 has multiple first glue inlet holes 1001, and the number and size of the first glue inlet holes 1001 are the same as the number and size of the glue outlet channels 1101. After rotation, the adhesive outlet channel 1101 of the sealing block 11 can be aligned with the first adhesive inlet hole 1001. The sealing ring 1102 is used to seal the first puncture shield 10 and the sealing block 11; A spike 1002 is provided below the first puncture cover 10, and a ridge is provided obliquely on the spike 1002 for puncturing the sealing membrane 8. The rotating disk 14 has a through hole 16, and the sealing plate 1401 is provided with a second puncture cover 18. The second puncture cover 18 has a second glue inlet hole 1801, and the bottom of the second puncture cover 18 is provided with a blade 1802. The blade 1802 can cut open the sealing membrane 8 when the filter cartridge 5 rotates.

[0017] When the adjusting handle 13 is in the open position, the glue outlet channel 1101 is aligned with the first glue inlet hole 1001, and the through hole 16 is aligned with the second puncture cover 18. When the adjusting handle 13 is in the closed position, the glue outlet channel 1101 is misaligned with the first glue inlet hole 1001, and the through hole 16 and the second puncture cover 18 are misaligned.

[0018] Working principle of this embodiment: During use, the dispensing tube 27 is connected to an external material supply system; When the feed pump 26 is working, it draws the glue into the settling and heating tank 24. During the process, the external transducer 2401 can shake out the air bubbles in the glue and prevent the glue from settling. After the glue enters the settling and heating tank 24, it falls from a height due to gravity. After settling and heating in the settling and heating tank 24, the air bubbles inside the glue are released. Then, by controlling the passages of electromagnetic three-way valve A 22 and electromagnetic three-way valve B 23, a filtration channel is opened; after the glue enters the filter cartridge 4, the differential pressure sensor 20 starts to work. When the differential pressure of any filter tank is greater than or equal to the set threshold, the control system triggers the electromagnetic three-way valve within 0.5 seconds to cut off the glue supply path of the blocked tank, switch to the standby tank for filtration, and simultaneously activate the audible and visual alarm to prompt the operator to replace the filter element 503. Subsequently, the filter cartridge shell 4 and filter cartridge 5, which had a pressure difference, were replaced. Rotate the adjusting handle 13 from the open position to the closed position. If it is necessary to rotate 90° between the open and closed positions, during the rotation, the rotating disk 14 and the sealing block 11 rotate synchronously. The through hole 16 is misaligned with the second puncture cover 18, and the glue outlet channel 1101 is misaligned with the first glue inlet hole 1001, so that the glue inlet channel 401 and the glue outlet channel 402 are sealed, thereby ensuring that after the filter cartridge 5 is removed, external gas cannot enter the glue channel. Then remove the old filter cartridge 5, and screw the new filter cartridge 5 into the filter cartridge housing 4 by holding the knob 502. Since the filter cartridge 5 has been vacuumed when it leaves the factory, there is no air inside the filter cartridge 5, and no gas will be generated during the replacement process. When the filter cartridge 5 is inserted into the threaded engagement point, the first sealing gasket 6 contacts the inner wall of the filter cartridge shell 4, thereby ensuring that the connection between the filter cartridge 5, the filter cartridge shell 4, and the sealing plate 1401 is sealed, and external gas cannot enter. As the filter cartridge 5 is fed by the thread, the spikes 1002 on the first puncture cover 10 and the blades 1802 on the second puncture cover 18 can puncture the sealing membrane 8 at the top of the filter cartridge 5. The first puncture cover 10 enters the interior of the filter element 503, and the second puncture cover 18 enters the glue passage chamber between the filter element 503 and the housing. Then, the adjusting handle 13 is rotated from the closed position to the open position to connect the device. No gas enters during the entire process. Subsequently, the glue enters the filter element 503 through the first glue inlet 1001, and after filtration, it seeps out into the glue passage chamber between the filter element 503 and the housing. Then the glue rises and flows out through the second glue inlet 1801 and out through the glue outlet channel 402.
