Description

Technical Field

[0001] This utility model relates to the field of coating, specifically to a coating material feeding system. Background Technology

[0002] Coating is a method of preparing composite materials (films) by applying a paste-like polymer, molten polymer, or polymer melt onto paper, cloth, or plastic film. In related technologies, a feeding system supplies the coating material to a coating head, which then coats the material onto the paper, cloth, or plastic film. However, due to insufficient mixing or other reasons, the material may contain large particles. These large particles can cause blockages in the feeding system. When the feeding system is blocked, the material cannot be supplied to the coating head, necessitating a shutdown for maintenance, thus halting the coating process and impacting production efficiency.

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following is for reference. Figures 1-3 This invention describes a coating material feeding system according to an embodiment of the present invention.

[0029] like Figures 1-3 As shown, the coating material feeding system of this utility model embodiment includes a mixing device 1, a storage device 2, and a filtering device 3.

[0030] The mixing device 1, the storage device 2, and the filtering device 3 are connected in series. The discharge end of the filtering device 3 is used to connect to the coating head 4. The storage device 2 includes at least two storage containers 21 connected in parallel. The filtering device 3 includes at least two filters 31 connected in parallel.

[0031] For example, such as Figure 1 As shown, the mixing device 1, the storage device 2, the filtering device 3 and the coating head 4 are connected in series through pipelines. The storage device 2 preferably includes, but is not limited to, two storage containers 21 connected in parallel, and the filtering device 3 preferably includes, but is not limited to, two filters 31 connected in parallel.

[0032] When the coating material feeding system is running, the mixing device 1 mixes multiple raw materials to form a material, and then supplies the material to the storage container 21 for storage. The two storage containers 21 can receive and store the material at the same time, or one of the storage containers 21 can receive and store the material. For example, when one of the storage containers 21 is blocked by large particles or is undergoing maintenance, the other storage container 21 receives and stores the material, thereby ensuring that there is always a storage container 21 that can receive and store the material when the system is running.

[0033] The material stored in storage container 21 is fed to filter 31 for filtration. Both filters 31 can filter the material simultaneously, or one filter 31 can filter the material. For example, when one filter 31 is clogged by large particles or undergoes maintenance, the other filter 31 filters the material, thus ensuring that one filter 31 is always available for filtration during system operation. The filtered material is then fed to coating head 4 for coating operations.

[0034] The coating material feeding system of this utility model embodiment includes a storage device comprising at least two storage containers connected in parallel, to ensure that at least one storage container is always available to receive material supplied by the mixing device during system operation and to supply the stored material to the filtering device. The filtering device includes at least two filters connected in parallel, to ensure that at least one filter is always available to receive and filter material supplied by the storage device during system operation and to supply the filtered material to the coating head. Therefore, the coating material feeding system of this utility model embodiment can ensure continuous material supply to the coating head.

[0035] In some embodiments, the filter device 3 further includes a first pressure sensor 32 and a second pressure sensor 33. The first pressure sensor 32 is provided in at least two corresponding to the filter 31 and is connected between the corresponding filter 31 and the storage device 2. The second pressure sensor 33 is provided in at least two corresponding to the filter 31 and is connected between the corresponding filter 31 and the coating head 4.

[0036] like Figure 1 As shown, the filtration device 3 includes at least two branches connected in parallel, preferably but not limited to two. Each branch is equipped with a first pressure sensor 32, a second pressure sensor 33, and a filter 31. Along the direction of material movement within the branch, the first pressure sensor 32, the filter 31, and the second pressure sensor 33 are arranged sequentially. The first pressure sensor 32 is used to obtain the pressure of the material before it is fed into the filter 31, and the second pressure sensor 33 is used to obtain the pressure of the material after it has been filtered by the filter 31. The difference between the pressure value obtained by the first pressure sensor 32 and the pressure value obtained by the second pressure sensor 33 can be used to determine whether the filter 31 is blocked. This allows the blocked filter 31 to be shut down and the supply of material to the blocked filter 31 to be stopped, so as to facilitate the maintenance and repair of the blocked filter 31.

[0037] In some embodiments, the filter device 3 further includes a first multi-way valve 34 and a second multi-way valve 35. The inlet of the first multi-way valve 34 is connected to the storage device 2, and the outlet of the first multi-way valve 34 is at least two corresponding to the filter 31. The inlet of the second multi-way valve 35 is at least two corresponding to the filter 31, and the outlet of the second multi-way valve 35 is used to connect to the coating head 4.

[0038] like Figure 1 As shown, the filter device 3 also includes a first multi-way valve 34 and a second multi-way valve 35. The first multi-way valve 34 includes an inlet and at least two outlets, preferably but not limited to two outlets. The inlet of the first multi-way valve 34 is connected to the storage device 2 through a pipeline, and the outlet of the first multi-way valve 34 is correspondingly connected to the branch provided with the first pressure sensor 32, the second pressure sensor 33 and the filter 31.

[0039] The second multi-way valve 35 includes one outlet and at least two inlets, preferably but not limited to two inlets. The inlet of the second multi-way valve 35 is connected to a branch equipped with a first pressure sensor 32, a second pressure sensor 33 and a filter 31. The outlet of the second multi-way valve 35 is connected to the coating head 4 through a pipeline.

[0040] Therefore, the outlet of the first multi-way valve 34 is correspondingly set with the inlet of the second multi-way valve 35, and a branch is connected between the outlet of the first multi-way valve 34 and the corresponding inlet of the second multi-way valve 35, which is equipped with a first pressure sensor 32, a second pressure sensor 33 and a filter 31, so that the first multi-way valve 34 controls whether the material enters the branch, and the second multi-way valve 35 controls whether the material in the branch is supplied to the coating head 4.

[0041] When one of the filters 31 becomes clogged, the first multi-way valve 34 disconnects the branch containing the clogged filter 31 from the storage device 2 to stop the supply of material, thereby facilitating maintenance and repair of the clogged filter 31 and its branch. Simultaneously, the first multi-way valve 34 keeps the branch containing the other filter 31 connected to the storage device 2 to ensure that the other filter 31 filters the material. The second multi-way valve 35 disconnects the branch containing the clogged filter 31 from the coating head 4 to prevent large particles in the material from entering the coating head 4 and causing it to become clogged. Simultaneously, the second multi-way valve 35 keeps the branch containing the other filter 31 connected to the storage device 2 to ensure a continuous supply of material to the coating head 4.

[0042] Furthermore, the first multi-way valve 34 and the second multi-way valve 35 are electric multi-way valves. The coating material feeding system also includes a control terminal. The control terminal is electrically connected to the first multi-way valve 34, the second multi-way valve 35, the first pressure sensor 32, and the second pressure sensor 33. The control terminal acquires the pressure values ​​transmitted by the first pressure sensor 32 and the second pressure sensor 33, and obtains the pressure difference between the pressure values ​​acquired by the first pressure sensor 32 and the second pressure sensor 33 on the same branch. The control terminal has a preset pressure range. When the pressure difference is not within the pressure range, it indicates that the filter 31 on that branch is blocked. The control terminal controls the first multi-way valve 34 and the second multi-way valve 35 to disconnect the branch where the blocked filter 31 is located from the storage device 2 and the coating head 4.

[0043] It is understood that, in other embodiments, the first multi-way valve 34 and the second multi-way valve 35 can also be manually adjusted after the values ​​obtained by the first pressure sensor 32 and the second pressure sensor 33 are read manually.

[0044] In some embodiments, the coating material feeding system further includes a first safety valve 8, wherein at least two first safety valves 8 are connected to the corresponding filter 31, and the first safety valve 8 is connected to the feed end of the corresponding filter 31.

[0045] like Figure 1 As shown, each branch of the filter device 3 is equipped with a first safety valve 8. The first safety valve 8 is preferably located between the first multi-way valve 34 and the first pressure sensor 32, or it can be located between the first pressure sensor 32 and the filter 31.

[0046] When the coating material supply system is running, the first safety valve 8 remains open. When the coating material supply system is shut down or an emergency occurs, such as a safety accident, the first safety valve 8 closes.

[0047] The first safety valve 8 is preferably, but not limited to, a manual valve.

[0048] In some embodiments, the storage container 21 includes a container body 211 and a first stirring assembly 212, at least a portion of which is located within the container body 211 to stir the material within the container body 211.

[0049] like Figure 1 and Figure 3 As shown, the storage container 21 includes a container body 211 and a first stirring component 212. The container body 211 is preferably, but not limited to, a tank. At least the lower end of the first stirring component 212 is located inside the container body 211 to stir the material stored inside the container body 211 and prevent the stored material from solidifying.

[0050] In some embodiments, the first stirring assembly 212 includes a first driving member 2121, a first support 2122, and a first wall scraping slurry 2123. The first end of the first support 2122 is located outside the container body 211 and connected to the first driving member 2121. The second end of the first support 2122 is located inside the container body 211 and connected to the first wall scraping slurry 2123. The first wall scraping slurry 2123 includes a first segment 21231 and a second segment 21232. The first segment 21231 is arranged side by side with the inner bottom surface of the container body 211, and the second segment 21232 is arranged side by side with the inner side surface of the container body 211. The first driving member 2121 is used to drive the first support 2122 to rotate around the axis of the first support 2122, thereby driving the first wall scraping slurry 2123 to rotate around the axis of the first support 2122.

[0051] like Figure 1and Figure 3 As shown, the first driving member 2121 is disposed on the top of the container body 211 and located outside the container body 211. The first driving member 2121 is preferably, but not limited to, a rotary motor.

[0052] The first support 2122 is preferably, but not limited to, a vertically arranged rod. The upper end of the first support 2122 extends from the top of the container body 211 and is coaxially or drive-connected to the first drive member 2121. The lower end of the first support 2122 is located inside the container body 211, and preferably on the vertical center line of the container body 211. The lower end of the first support 2122 is connected to the first scraping slurry 2123. The first scraping slurry 2123 is preferably, but not limited to, at least two, more preferably two, and the at least two first scraping slurries 2123 are arranged at intervals around the axis of the first support 2122.

[0053] The first wall scraping slurry 2123 includes a first section 21231 and a second section 21232. The first section 21231 is connected to the lower end of the first support 2122 and extends from the first support 2122 toward the inner circumferential surface of the container body 211 in a direction parallel to the inner bottom surface of the container body 211. The second section 21232 is connected to the end of the first section 21231 away from the first support 2122 and extends upward from the first section 21231 in a direction parallel to the inner circumferential surface of the container body 211, so that the first section 21231 is arranged side by side with the inner bottom surface of the container body 211 and the second section 21232 is arranged side by side with the inner circumferential surface of the container body 211.

[0054] When the first stirring assembly 212 is running, the first driving member 2121 drives the first support 2122 to rotate around the axis of the first support 2122, in other words, drives the first support 2122 to rotate in the vertical direction. The first support 2122 drives the first scraper slurry 2123 to rotate in the vertical direction, so that the first scraper slurry 2123 stirs the material inside the container body 211. At the same time, the first section 21231 scrapes off or stirs the material attached to the inner bottom surface of the container body 211, and the second section 21232 scrapes off or stirs the material attached to the inner circumferential surface of the container body 211, thereby preventing the material from solidifying.

[0055] In some embodiments, the storage device 2 further includes an inlet valve 22 and an outlet valve 23. There are at least two inlet valves 22 corresponding to the storage container 21, and the inlet valves 22 are connected between the corresponding storage container 21 and the mixing device 1. There are at least two outlet valves 23 corresponding to the storage container 21, and the outlet valves 23 are connected between the corresponding storage container 21 and the filtering device 3.

[0056] like Figure 1 and Figure 3As shown, each storage container 21 is provided with a feed pipe at the top. The two feed pipes are connected in parallel to the pipeline connecting the storage device 2 and the mixing device 1. The feed pipe is provided with a feed valve 22 for controlling its opening and closing.

[0057] Each storage container 21 is equipped with a discharge pipe at its bottom. The two discharge pipes are connected in parallel to the pipeline connecting the storage device 2 and the filter device 3. The discharge pipe is equipped with a discharge valve 23 for controlling its opening and closing.

[0058] The material supplied by the mixing device 1 is controlled by the feed valve 22 to enter the storage container 21, and the material in the storage container 21 is controlled by the discharge valve 23 to supply the filter device 3. When the material in one of the storage containers 21 contains large particles or has solidified, the feed valve 22 and discharge valve 23 connected to that storage container 21 are closed to maintain and repair the storage container 21. At the same time, the feed valve 22 and discharge valve 23 connected to the other storage container 21 are kept open to ensure the operation of the other storage container 21. This ensures that there is always a storage container 21 that can receive the material supplied by the mixing device 1 and supply the stored material to the filter device 3, thereby ensuring a continuous supply of material to the coating head 4. Of course, both storage containers 21 can also operate simultaneously.

[0059] The feed valve 22 and the discharge valve 23 are preferably, but not limited to, electric valves.

[0060] In some embodiments, the coating material feeding system of this utility model further includes a feeding pump 5, which is connected between the discharge valve 23 and the filter device 3.

[0061] like Figure 1 As shown, the two discharge pipes of the storage device 2 are connected in parallel to the inlet end of the feed pump 5, and the outlet end of the feed pump 5 is connected to the inlet of the first multi-way valve 34 through a pipeline to supply the material stored in the storage container 21 to the filter device 3.

[0062] It should be noted that the material stored in the storage device 2 can only be supplied to the filter device 3 when both the discharge valve 23 and the feed pump 5 are open. If either the discharge valve 23 or the feed pump 5 is closed, the material stored in the storage device 2 cannot be supplied to the filter device 3. Therefore, the simultaneous installation of the discharge valve 23 and the feed pump 5 serves as a double safety measure.

[0063] Preferably, the discharge valve 23 and the feed pump 5 are both electrically connected to the control terminal. The control terminal has preset conditions corresponding to the discharge valve 23 and the feed pump 5 respectively. When the system reaches the corresponding preset conditions, the control terminal will open the discharge valve 23 or the feed pump 5 corresponding to the preset conditions.

[0064] In some embodiments, the coating material feeding system of this utility model further includes a second safety valve 9. There are at least two second safety valves 9 corresponding to the storage container 21, and the second safety valves 9 are connected to the discharge end of the corresponding storage container 21.

[0065] like Figure 1 and Figure 3 As shown, each storage container 21 has a second safety valve 9 at the bottom of the discharge pipe. The second safety valve 9 is preferably located between the storage container 21 and the discharge valve 23, or it can be located between the discharge valve 23 and the feed pump 5.

[0066] When the coating material supply system is running, the second safety valve 9 remains open. When the coating material supply system is shut down or an emergency occurs, such as a safety accident, the second safety valve 9 closes.

[0067] The second safety valve 9 is preferably, but not limited to, a manual valve.

[0068] In some embodiments, the mixing device 1 includes a mixing container 11 and a second stirring assembly 12, at least a portion of which is located inside the mixing container 11 to stir the material inside the mixing container 11.

[0069] like Figure 1 and Figure 2 As shown, the mixing device 1 includes a mixing container 11 and a second stirring component 12. The mixing container 11 is preferably, but not limited to, a tank. At least the lower end of the second stirring component 12 is located inside the mixing container 11 to stir the various raw materials that are put into the mixing container 11, so that the various raw materials are fully mixed and form a material.

[0070] In some embodiments, the second stirring assembly 12 includes a second driving member 121, a second support 122, a second wall scraper 123, a dispersion slurry 124, and a stirring slurry 125. The first end of the second support 122 is located outside the mixing container 11 and connected to the second driving member 121. The second end of the second support 122 is located inside the mixing container 11 and connected to the second wall scraper 123, the dispersion slurry 124, and the stirring slurry 125. At least two stirring slurries 125 are arranged at intervals around the axis of the second support 122, and the stirring slurries 125 are bent or spiral-shaped extending along the axial direction of the second support 122. The dispersion slurry 124 and the second wall scraper slurry 123 are disposed on the outer periphery of the at least two stirring slurries 125. The second wall scraper slurry 123 is arranged side by side with the inner side of the mixing container 11. The dispersion slurry 124 includes a shaft 1241 and a blade 1242 disposed on the shaft 1241.

[0071] like Figure 1 and Figure 2 As shown, the second drive member 121 is disposed on the top of the mixing container 11 and located outside the mixing container 11. The second drive member 121 is preferably, but not limited to, a rotary motor.

[0072] The upper end of the second support 122 extends vertically and protrudes from the top of the mixing container 11. The upper end of the second support 122 is coaxially or drive-connected to the second drive member 121. The lower end of the second support 122 is located inside the mixing container 11 and is preferably, but not limited to, a horizontally extending plate or grid. The lower end of the second support 122 is connected to the second scraper slurry 123, the dispersion slurry 124 and the stirring slurry 125.

[0073] The agitator 125 is connected to the middle of the lower end of the second support 122 and extends downward from the second support 122. The agitator 125 is a bent or spiral shape extending from top to bottom. There are at least two agitators 125, preferably three, and the three agitators 125 are arranged at intervals around the axis of the second support 122.

[0074] The dispersing slurry 124 and the second wall-scraping slurry 123 are connected to the lower end of the second support 122 and are located further away from the axis of the second support 122 relative to its connection point. Both the dispersing slurry 124 and the second wall-scraping slurry 123 extend downwards from the second support 122 and are arranged at intervals along the circumference of the second support 122. In other words, the dispersing slurry 124 and the second wall-scraping slurry 123 surround the outer periphery of at least two stirring paddles 125. It should be noted that the distance between the axis of the dispersing slurry 124 and the axis of the second support 122 can be the same or different from the distance between the second wall-scraping slurry 123 and the axis of the second support 122.

[0075] The dispersion slurry 124 extends from top to bottom along the inner circumferential surface of the mixing container 11, so that the dispersion slurry 124 is arranged side by side. Preferably, at least two dispersion slurries 124 are arranged at intervals in the vertical direction, more preferably two.

[0076] The second wall scraping slurry 123 includes a slurry shaft 1241 that is connected to the second support 122 and extends downward, and at least two blades 1242 that are disposed on the slurry shaft 1241 and arranged at intervals in the vertical direction.

[0077] When the second mixing assembly 12 is running, the second drive member 121 drives the second support 122 to rotate around its axis, or in other words, drives the second support 122 to rotate vertically. The second support 122 drives the mixing paddle 125 to rotate vertically, so that the mixing paddle 125 agitates and mixes the raw materials. The second support 122 also drives the dispersing paddle 124 to rotate vertically to further agitate and mix the raw materials. Thus, the mixing paddle 125 and the dispersing paddle 124 work together to mix the raw materials and form a material. At the same time, the second support 122 drives the second wall scraper 123 to rotate vertically. The second wall scraper 123 scrapes off or agitates the material or raw materials adhering to the inner circumferential surface of the mixing container 11, preventing insufficient mixing and material solidification.

[0078] In some embodiments, the coating material feeding system of this utility model further includes a discharge valve 6, which is connected between the mixing device 1 and the storage device 2.

[0079] like Figure 1 and Figure 2 As shown, the mixing container 11 is connected to the storage device 2 through a feeding pipeline. The discharge end of the feeding pipeline is connected in parallel to two inlet pipes of the storage device 2. The inlet end of the feeding pipeline is equipped with a discharge valve 6. The opening and closing of the discharge valve 6 controls whether the material in the mixing container 11 is supplied to the storage device 2 by the feeding pipeline. In other words, the discharge valve 6 controls whether the mixing container 11 discharges material.

[0080] When the various raw materials in the mixing container 11 are not fully mixed, the discharge valve 6 is closed. After the various raw materials in the mixing container 11 are fully mixed and form material, the discharge valve 6 is opened to supply the material.

[0081] The discharge valve 6 is preferably, but not limited to, an electric valve.

[0082] In some embodiments, the coating material feeding system of this utility model further includes a feeding pump 7, which is connected between the discharge valve 6 and the storage device 2.

[0083] like Figure 1 As shown, the feed pump 7 is located on the feed pipeline connecting the mixing container 11 and the storage device 2 to supply the material released from the mixing container 11 to the storage device 2. The discharge valve 6 is preferably, but not limited to, located between the feed pump 7 and the mixing container 11.

[0084] It should be noted that the material in the mixing container 11 can only be supplied to the storage device 2 when both the discharge valve 6 and the feed pump 7 are open. If either the discharge valve 6 or the feed pump 7 is closed, the material in the mixing container 11 cannot be supplied to the storage device 2. Therefore, the simultaneous installation of the discharge valve 6 and the feed pump 7 serves as a double safety measure.

[0085] Preferably, both the discharge valve 6 and the feed pump 7 are electrically connected to the control terminal. The control terminal has preset conditions corresponding to the discharge valve 6 and the feed pump 7 respectively. When the system reaches the corresponding preset conditions, the control terminal will open the discharge valve 6 and the feed pump 7 corresponding to the preset conditions.

[0086] In some embodiments, the coating material feeding system of this utility model further includes a third safety valve 10, which is connected to the discharge end of the mixing device 1.

[0087] like Figure 1 and Figure 2 As shown, the feed pipeline is equipped with a third safety valve 10 at the feed inlet. The third safety valve 10 is preferably located between the mixing container 11 and the discharge valve 6, or it can be located between the discharge valve 6 and the feed pump 7.

[0088] When the coating material supply system is running, the third safety valve 10 remains open. When the coating material supply system is shut down or an emergency occurs, such as a safety accident, the third safety valve 10 closes.

[0089] The third safety valve 10 is preferably, but not limited to, a manual valve.
