The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0036] Please see Figures 1 to 4 The feeding system 100 includes a heater 1, a heat transfer fluid 2, a feeding tank 3, a spare tank 4, a feeding component 5, a pipe 6, a return pipe 7, a first inlet pipe 8, a second inlet pipe 9, a third inlet pipe 10, a return pipe 11, and a stirring paddle 12. The heater 1 heats the heat transfer fluid 2. Both the feeding tank 3 and the spare tank 4 store material 300, with one tank in use and the other in reserve, ensuring uninterrupted supply of material 300. The pipe 6 connects the feeding tank 3 and the feeding component 5 for feeding material, or the pipe 6 connects the spare tank 4 and the feeding component 5 for feeding material. The return pipe 7 connects the feeding component 5 and the feeding tank 3 for returning material 300 to the feeding tank 3. The stirring paddle 12 is located in the feeding tank 3 for stirring. The heat transfer fluid 2 is used to circulate in the heater 1, the feeding tank 3, the spare tank 4 and the feeding component 5 through the first inlet pipe 8, the second inlet pipe 9, the third inlet pipe 10 and the return pipe 11 to heat the material 300 in the feeding tank 3, the spare tank 4 and the feeding component 5, thereby reducing the risk of local overheating.
[0037] Regarding the heater 1 and the heat transfer fluid 2 mentioned above, heater 1 is a device used to heat the heat transfer fluid 2. Heater 1 can be a resistance heating element, an electromagnetic induction heater, or a heat pump, etc. A resistance heating element generates heat through current and directly transfers the heat to the heat transfer fluid 2. An electromagnetic induction heater 1 utilizes the principle of electromagnetic induction to generate eddy currents in the heat transfer fluid 2; these eddy currents generate heat, thereby heating the fluid. A heat pump, through the circulation of the working medium, absorbs heat from a low-temperature heat source and releases it at a high temperature, thus heating the heat transfer fluid 2. All these heaters 1 can effectively heat the heat transfer fluid 2 to meet the temperature requirements of the feeding system 100.
[0038] In some embodiments, in order to ensure that the heat transfer fluid 2 has a suitable operating temperature, the heater 1 has a preset temperature T, for example, 75°C.
[0039] In some embodiments, the heater 1 is equipped with a switch 101, a first indicator light 102, a second indicator light 103, a display 104, a first temperature adjustment button 105, and a second temperature adjustment button 106. The switch 101 is used to start the heater 1, the first indicator light 102 is used to indicate the first working state of the heater 1, the second indicator light 103 is used to indicate the second working state of the heater 1, the display 104 is used to display the preset temperature T and the real-time temperature of the heater 1, and both the first temperature adjustment button 105 and the second temperature adjustment button 106 are used to adjust the preset temperature. The first temperature adjustment button 105 is used to increase the preset temperature, and the second temperature adjustment button 106 is used to decrease the preset temperature. Through the design of these multiple functions, the heater 1 can easily heat the heat transfer fluid 2.
[0040] It is worth noting that in some embodiments, the first indicator light 102 indicates red, and the first indicator light 102 being lit indicates that the heater 1 is in a heating state; the second indicator light 103 indicates green, and the second indicator light 103 being lit indicates that the heater 1 has reached the preset temperature.
[0041] For the aforementioned heat transfer fluid 2, first inlet pipe 8, second inlet pipe 9, third inlet pipe 10, and return pipe 11, the first inlet pipe 8 is connected between the heater 1 and the feeding tank 3, the second inlet pipe 9 is connected between the feeding tank 3 and the spare tank 4, the third inlet pipe 10 is connected between the spare tank 4 and the feeding component 5, and the return pipe 11 is connected between the feeding component 5 and the heater 1. The heat transfer fluid 2 is a medium used to transfer heat, such as water, oil, or other suitable fluid. After being heated in the heater 1, the heat transfer fluid 2 flows into the feeding tank 3 through the first inlet pipe 8, into the spare tank 4 through the second inlet pipe 9, into the feeding component 5 through the third inlet pipe 10, and then returns to the heating element through the return pipe 11, circulating among the heater 1, feeding tank 3, spare tank 4, and feeding component 5, thereby heating the material 300 in the feeding tank 3, spare tank 4, and feeding component 5. This circulating heating method not only improves heating efficiency but also ensures the uniformity of material temperature 300, avoiding damage or quality degradation of material 300 caused by localized overheating. Furthermore, the circulating use of the heat transfer fluid 2 also improves energy utilization efficiency and reduces energy consumption.
[0042] It is worth noting that in some embodiments, the first inlet pipe 8, the second inlet pipe 9, the third inlet pipe 10, and the return pipe 11 are all made of stainless steel, which has good corrosion resistance and high temperature resistance, ensuring that the heat transfer fluid 2 flows stably and that the heat transfer efficiency is not affected by material issues.
[0043] The feeding hopper 3 is used to store material 300 and to heat the material 300 through the heat transfer fluid 2.
[0044] In some embodiments, the feeding hopper 3 is provided with a first receiving cavity 301 and a first hollow cavity 302 that are independent of each other. The first receiving cavity 301 is used to receive material 300, and the first hollow cavity 302 is arranged around the first receiving cavity 301. The feeding hopper 3 is provided with a first liquid outlet 303 that communicates with the first receiving cavity 301, and a first inlet 304 and a first outlet 305 that communicate with the first hollow cavity 302. The first inlet 304 is connected to the first inlet pipe 8, and the heat transfer fluid 2 used for heating in the heater 1 enters the first hollow cavity 302, thereby heating the material 300 in the first receiving cavity 301. The first outlet 305 is connected to the second inlet pipe 9, and the heat transfer fluid 2 flows into the spare hopper 4. This method of filling the first hollow cavity 302 with heat transfer fluid 2 to heat the material 300 in the first receiving cavity 301 surrounding the first hollow cavity 302 significantly reduces the risk of local overheating of the material 300.
[0045] It is worth noting that in some embodiments, the heat transfer fluid 2 adopts a bottom-in, top-out configuration in the first hollow cavity 302, that is, the first inlet 304 is located at the lower end of the feeding tank 3, and the first outlet 305 is located at the upper end of the feeding tank 3. Through this design, the heat transfer fluid 2 can more fully exchange heat with the material 300 in the first receiving cavity 301, improving heating efficiency and heating uniformity. At the same time, this bottom-in, top-out flow pattern also helps to reduce the risk of dead zones forming in the heat transfer fluid 2 in the first hollow cavity 302, further improving heat transfer efficiency.
[0046] In some embodiments, the feeding hopper 3 includes a first hopper body 31 and a first cover 32. The first hopper body 31 is provided with a first receiving cavity 301 and a first opening 311 communicating with the first receiving cavity 301. The first cover 32 is sealed to the first hopper body 31 to close the first opening 311. The first hollow cavity 302 may be located on the hopper wall and the bottom of the first hopper body 31.
[0047] In some embodiments, the first cover 32 is provided with a through hole 321, which is used for the return pipe 7 to be inserted into the first cover 32, so that the material 300 in the feeding component 5 can flow back to the first receiving cavity 301 of the feeding bucket 3.
[0048] It is worth noting that in some embodiments, the first liquid outlet 303 is located on the side of the first barrel 31 facing away from the first cover 32, thereby facilitating the use up of the material 300 in the first receiving cavity 301.
[0049] In some embodiments, the feeding hopper 3 further includes a first steering pulley 33, which is disposed on the side of the first hopper body 31 facing away from the first cover 32. The first steering pulley 33 facilitates the movement of the feeding hopper 3.
[0050] Regarding the aforementioned feeding hopper 3 and stirring paddle 12, the stirring paddle 12 is disposed in the feeding hopper 3, and the output end of the stirring paddle 12 is located in the first receiving cavity 301 of the feeding hopper 3. Through the placement of the stirring paddle 12, the material 300 in the feeding hopper 3 can be stirred. When the material 300 in the feeding component 5 flows back to the first receiving cavity 301 of the feeding hopper 3 through the return pipe 7, the stirring paddle 12 mixes and stirs the original material 300 in the feeding hopper 3 and the material 300 flowing back from the feeding component 5 to ensure the uniformity and consistency of the material 300. The stirring speed and stirring time of the stirring paddle 12 can be adjusted according to actual needs to achieve the best stirring effect. In some embodiments, the driving device of the stirring paddle 12 can be disposed outside the feeding hopper 3 and connected to the stirring paddle 12 through a transmission device to realize the rotation of the stirring paddle 12. This design not only facilitates the maintenance and replacement of the stirring paddle 12, but also avoids the occupation of the internal space of the feeding hopper 3 by the driving device of the stirring paddle 12, thus improving the utilization rate of the feeding hopper 3. In addition, the material of the mixing paddle 12 also needs to have good corrosion resistance and high temperature resistance to ensure that the mixing paddle 12 will not be damaged by corrosion or high temperature during long-term use, thus affecting the mixing effect and the normal operation of the feeding system 100.
[0051] The aforementioned spare container 4 is used to store material 300 and to heat the material 300 through the heat transfer fluid 2.
[0052] In some embodiments, the spare container 4 is provided with a second receiving cavity 401 and a second hollow cavity 402 that are independent of each other. The second receiving cavity 401 is used to receive material 300, and the second hollow cavity 402 is arranged around the second receiving cavity 401. The spare container 4 is provided with a second liquid outlet 403 that communicates with the second receiving cavity 401, and a second inlet 404 and a second outlet 405 that communicate with the second hollow cavity 402. The second inlet 404 is connected to the second inlet pipe 9 for supplying heat transfer fluid 2 from the material container 3 into the second hollow cavity 402, thereby heating the material 300 in the second receiving cavity 401. The second outlet 405 is connected to the third inlet pipe 10 for the heat transfer fluid 2 to flow into the spare container 4. This method of filling the second hollow cavity 402 with heat transfer fluid 2 to heat the material 300 in the second receiving cavity 401 surrounding the second hollow cavity 402 significantly reduces the risk of local overheating of the material 300.
[0053] It is worth noting that in some embodiments, the heat transfer fluid 2 adopts a bottom-in, top-out configuration in the second hollow cavity 402, that is, the second inlet 404 is located at the lower end of the spare container 4, and the second outlet 405 is located at the upper end of the spare container 4. Through this design, the heat transfer fluid 2 can more fully exchange heat with the material 300 in the second receiving cavity 401, improving heating efficiency and heating uniformity. At the same time, this bottom-in, top-out flow pattern also helps to reduce the risk of dead zones forming in the heat transfer fluid 2 in the second hollow cavity 402, further improving heat transfer efficiency.
[0054] In some embodiments, the spare bucket 4 includes a second bucket body 41 and a second cover 42. The second bucket body 41 is provided with a second receiving cavity 401 and a second opening 411 communicating with the second receiving cavity 401. The second cover 42 is sealed to the second bucket body 41 to close the second opening 411. The second hollow cavity 402 may be located on the bucket wall and the bottom of the second bucket body 41.
[0055] It is worth noting that in some embodiments, the feeding tank 3 is equipped with the stirring paddle 12, while the spare tank 4 does not have a stirring device. This is because the feeding tank 3 is connected to the feeding component 5 via a return pipe 7, and the material 300 in the feeding component 5 flows back to the feeding tank 3. The spare tank 4, however, is not connected to the return pipe 7 and does not receive excess material 300 from the feeding component 5. Therefore, the material 300 in the spare tank 4 will not experience uneven mixing due to the return of material 300. Not including a stirring device in the spare tank 4 saves system costs and simplifies the structure.
[0056] It is worth noting that in some embodiments, the second liquid outlet 403 is located on the side of the second barrel 41 facing away from the second cover 42, thereby facilitating the use up of the material 300 in the second receiving cavity 401.
[0057] In some embodiments, the spare container 4 further includes a second steering pulley 43, which is disposed on the side of the second container body 41 facing away from the second cover 42. The second steering pulley 43 facilitates the movement of the spare container 4.
[0058] For the aforementioned feeding component 5, pipe 6, and return pipe 7, the feeding component 5 is provided with an independent feeding trough 501 and an inner cavity 502. The inner cavity 502 surrounds the feeding trough 501. The feeding component 5 is provided with an inlet 503 and a return port 504 connecting the feeding trough 501. The feeding component 5 is also provided with an inlet 505 and a return port 506 connecting the inner cavity 502. The feeding trough 501 is used to feed material for use by the coating roller 200. The first outlet 303 of the feeding tank 3 is connected to the inlet 503 through the pipe 6, so that the material 300 in the feeding tank 3 is supplied to the feeding trough 501. The return port 504 is connected to the first receiving cavity 301 of the feeding tank 3 through the return pipe 7 and the through hole 321, so that the material 300 in the feeding trough 501 flows back to the first receiving cavity 301, reducing the risk of material 300 waste.
[0059] In addition, in some embodiments, the return port 504 is located near the opening of the feed tank 501 so that excess material 300 on the coating roller 200 can flow back smoothly to the feed tank 501, and then flow back to the feed bucket 3 through the return pipe 7, thereby realizing the recycling of material 300.
[0060] The inlet 505 is connected to the second outlet 405 of the spare tank 4 through the third inlet pipe 10, so that the heat transfer fluid 2 can enter the inner cavity 502 to heat the material 300 in the feeding tank 501 and ensure the operating temperature of the material 300.
[0061] The return port 506 is connected to the heater 1 through the return pipe 11, so as to realize the circulation of the heat transfer fluid 2 between the heater 1, the feeding bucket 3, the spare bucket 4 and the feeding component 5.
[0062] Among them, pipe 6 is made of stainless steel, which has good corrosion resistance and high temperature resistance, ensuring stable flow of material 300 and preventing material transfer efficiency from being affected by material issues.
[0063] Among them, the return pipe 7 is made of stainless steel, which has good corrosion resistance and high temperature resistance, ensuring stable flow of material 300 and preventing material transfer efficiency from being affected by material issues.
[0064] In some embodiments, a first thermometer 13 is provided in the feeding tank 501. The first thermometer 13 is used to indicate a first temperature value T1, where 15℃≤T-T1≤25℃. Here, T is a preset temperature set by the heater 1. The preset temperature is higher than the temperature in the feeding tank 501, establishing temperature compensation to consider heat loss during the circulation of the heat transfer fluid 2 between various components, ensuring that the temperature in the feeding tank 501 is a suitable operating temperature for the material 300. When the temperature in the feeding tank 501 reaches the aforementioned first temperature value, it indicates that the material 300 in the material 300 tank is in a suitable operating state.
[0065] In some embodiments, a second thermometer 14 is provided at the inlet 505. The second thermometer 14 is used to indicate a second temperature value T2, where 0℃≤T2-T1≤5℃, to finely control the temperature of the heat transfer fluid 2 at the inlet 505. When the temperature of the heat transfer fluid 2 at the inlet 505 reaches the second temperature value, it can ensure that the material 300 in the material 300 tank is in a suitable working state, thereby improving the accuracy of temperature control of the material 300 in the material 300 tank.
[0066] In some embodiments, a third thermometer 15 is provided at the first outlet 305. The third thermometer 15 is used to indicate a third temperature value T3, where 5℃≤T3-T1≤10℃, so as to more precisely control the temperature of the heat transfer fluid 2 in each link, establish temperature compensation, consider the heat loss when the heat transfer fluid 2 circulates between various components, and ensure that the temperature in the feeding tank 501 is the appropriate operating temperature of the material 300.
[0067] In some embodiments, a fourth thermometer 16 is provided at the first inlet 304. The fourth thermometer 16 is used to indicate a fourth temperature value T4. The fourth temperature value T4 has a slight difference from the third temperature value T3, for example, 2°C. By adding the fourth thermometer 16, the temperature of the heat transfer fluid 2 in each stage can be controlled more precisely, temperature compensation can be established, and the heat loss of the heat transfer fluid 2 when circulating between various components can be taken into account, so as to further ensure that the temperature in the feeding tank 501 is the appropriate operating temperature of the material 300.
[0068] It is understandable that thermometers can also be installed at the second inlet 404 and the second outlet 405 of the spare tank 4 to more precisely control the temperature of the heat transfer fluid 2 at each stage, and further ensure that the temperature in the feed tank 501 is the appropriate operating temperature for the material 300.
[0069] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 5The feeding system 100 also includes a temperature control system 17, which is connected to the heater 1, the first thermometer 13, the second thermometer 14, the third thermometer 15, and the fourth thermometer 16 to monitor the temperature of each component of the feeding system 100 in real time. Furthermore, the temperature control system 17 establishes a temperature compensation model based on different operating conditions and ambient temperatures. For example, in winter when the ambient temperature is low, it automatically increases the temperature compensation value of heater 1 by +5 degrees, with a preset temperature of 80 degrees; in summer when the ambient temperature is high, it appropriately reduces the compensation value to ensure that the temperature in the feeding tank 501 always meets the process requirements.
[0070] It is worth noting that the program steps involved in the temperature control system 17 are existing program steps, and the temperature control system 17 also uses existing control systems.
[0071] In some embodiments, the feeding system 100 further includes a first valve 18 and a second valve 19, the first valve 18 being disposed at the first liquid outlet 303, and the second valve 19 being disposed at the second liquid outlet 403, the pipe 6 (e.g. Figure 1 (As shown) connects the first outlet 303 and the inlet 503 to allow the material 300 in the first receiving cavity 301 to enter the feeding tank 501; when the material 300 in the feeding tank 3 is exhausted, the first valve 18 is used to cut off the flow, and the pipe 6 (as ... Figure 2 As shown, the second outlet 403 is connected to the inlet 503. The second valve 19 is used to supply flow so that the material 300 in the second receiving cavity 401 enters the feeding trough 501. When the pipe 6 is connected to the first outlet 303 and the inlet 503, that is, when the feeding bucket 3 supplies material to the feeding trough 501, the first valve 18 is used to supply flow, and the second valve 19 is used to limit flow. Through this feeding system 100, the feeding bucket 3 and the spare bucket 4 are used in one and standby respectively. When the material 300 in the feeding bucket 3 is exhausted, the spare bucket 4 can be replaced in time to supply material. There is no need to replenish the feeding bucket 3. The spare bucket 4 can be used to supply material 300, so as to achieve uninterrupted production and improve production efficiency.
[0072] In some embodiments, "exhausted" indicates that the material 300 in the feed tank 3 can no longer flow into the feed trough 501 through the pipe 6. In other embodiments, "exhausted" indicates that the material 300 in the feed tank 3 has reached a preset liquid level.
[0073] In some embodiments, the feeding system 100 further includes a first quick connector (not shown), a portion of which is located at the first liquid outlet 303, and another portion of which is located at the end of the pipe 6 that communicates with the first liquid outlet 303. The first quick connector facilitates quick disassembly between the pipe 6 and the feeding bucket 3.
[0074] The first quick connector can adopt existing technologies, such as CN119914768A, CN112303365A, CN108317324A, etc., and the specific one can be reasonably selected according to actual needs.
[0075] In some embodiments, the feeding system 100 further includes a second quick connector (not shown) located at the second liquid outlet 403, the second quick connector being used to mate with another portion of the first quick connector. The second quick connector may also employ existing technology, for example, having the same structure as a portion of the first quick connector, thereby facilitating mates with the other portion of the first quick connector.
[0076] In some embodiments of this application, such as Figure 6 and Figure 3As shown, the feeding system 100 includes a heater 1, a heat transfer fluid 2, a feeding hopper 3, and a feeding component 5. The feeding hopper 3 has an independent first receiving cavity 301 and a first hollow cavity 302. The first receiving cavity 301 is used to receive material 300, and the first hollow cavity 302 surrounds the first receiving cavity 301. The feeding hopper 3 has a first liquid outlet 303 communicating with the first receiving cavity 301, and a first inlet 304 and a first outlet 305 communicating with the first hollow cavity 302. The feeding component 5 has an independent feeding trough 501 and an inner cavity 502, with the inner cavity 502 surrounding the feeding trough 501. Component 5 is provided with an inlet 503 connecting the feeding tank 501 and an inlet 505 and a return port 506 connecting the inner cavity 502; the first outlet 303 is connected to the inlet 503 so that the material 300 in the first receiving cavity 301 enters the feeding tank 501; the heater 1, the first inlet 304, the first outlet 305, the inlet 505 and the return port 506 are connected in sequence, the heater 1 is used to heat the heat transfer fluid 2, and the return port 506 is connected to the heater 1 so that the heat transfer fluid 2 circulates in the heater 1, the first hollow cavity 302 and the inner cavity 502. Through the feeding system 100, the heater 1 heats the heat transfer fluid 2, which circulates in the heater 1, the first hollow cavity 302 and the inner cavity 502, heating the material 300 in the feeding barrel 3 and the material 300 flowing into the feeding trough 501 of the feeding component 5 for use. This not only reduces the risk of local overheating of the material 300, but also ensures the operating temperature of the material 300 and the flowability of the material 300. When the material 300 is a non-silicone release agent, it can ensure the uniformity of coating and significantly improve the release quality of the product.
[0077] In some embodiments of this application, such as Figure 7 and Figure 8As shown, the feeding system 100 includes a feeding hopper 3, a feeding component 5, a spare hopper 4, a first valve 18, a second valve 19, a pipe 6, and a stirring paddle 12; the feeding hopper 3 is provided with a first receiving cavity 301 and a first liquid outlet 303 communicating with the first receiving cavity 301, the first receiving cavity 301 being used to receive material 300; the spare hopper 4 is provided with a second receiving cavity 401 and a second liquid outlet 403 communicating with the second receiving cavity 401, the second receiving cavity 401 being used to receive material 300; the feeding component 5 is provided with a feeding trough 501 and a liquid inlet 503 communicating with the liquid outlet 504 of the feeding trough 501; the first valve 18 is located at the first liquid outlet 303, the second valve 19 is located at the first liquid outlet 303, the second valve 19 is located at the second liquid outlet 6, and the second valve 19 is located at the second liquid outlet 6; the feeding component 5 is provided with a feeding trough 501 and a liquid inlet 503 communicating with the liquid outlet 504 of the feeding trough 501; the first valve 18 ... A valve 9 is located at the second liquid outlet 403. The pipe 6 connects the first liquid outlet 303 and the liquid inlet 503, allowing the material 300 in the first receiving cavity 301 to enter the feeding tank 501. The return port 504 connects to the first receiving cavity 301. The stirring paddle 12 is located at the feeding tank 3, with its output end situated in the first receiving cavity 301. When the material 300 in the feeding tank 3 is depleted, the first valve 18 is used to cut off the flow. The pipe 6 connects the second liquid outlet 403 and the liquid inlet 503, and the second valve 19 is used to supply the flow, allowing the material 300 in the second receiving cavity 401 to enter the feeding tank 501. Through this feeding system 100, the feeding tank 3 and the spare tank 4 are used in one and standby respectively. When the material 300 in the feeding tank 3 is depleted, the spare tank 4 can be replaced in time for feeding, eliminating the need to replenish the feeding tank 3. This allows for continuous production and improves production efficiency.
[0078] In addition, the material 300 in the feeding tank 501 can enter the first receiving cavity 301 of the feeding barrel 3 from the return port 504, saving the use of material 300.
[0079] Equally important, a stirring paddle 12 is installed in the feeding tank 3 to mix the material 300 returning from the feeding trough 501 with the material 300 in the feeding tank 3, thereby improving the uniformity of the material 300 supply. In addition, since the spare tank 4 is not connected to the return port 504, it does not need to be equipped with a stirring paddle 12, reducing the burden on the equipment.
[0080] This application also provides an embodiment of a production line, which includes the feeding system 100. The specific structure and function of the feeding system 100 can be found in the above embodiments, and will not be repeated here.
