Description

[0002] In the field of contemporary industrial production, coating technology is widely used in the processing and manufacturing of various materials, including paper, film, textiles and other materials. In the coating process, the die head plays a vital role as a key component to achieve uniform coating. However, as the running time increases, coating residues, dust and other impurities will gradually accumulate on the die head. These contaminants will damage the coating quality, resulting in defects such as streaks, bubbles, uneven coating, and difficulty in adjusting the T block due to the solidification of residual slurry. Therefore, regular cleaning of the die head is essential to ensure coating quality and improve production efficiency.

[0003] At present, die cleaning technologies on the market include manual cleaning and ultrasonic cleaning. However, these methods all have certain limitations: manual cleaning is inefficient, time-consuming and labor-intensive, and it is difficult to completely remove dirt inside the die, resulting in unsatisfactory cleaning results; although ultrasonic cleaning has a better cleaning effect, its equipment cost is high, and the die needs to be disassembled and reinstalled, and the operation process is complicated, so it is not suitable for frequent use. In view of the above problems, this application document proposes a new coating die design, which aims to achieve efficient cleaning to solve the deficiencies in the prior art. Utility Model Content

[0040] Furthermore, the present utility model is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein.

[0041] Please refer to the attached Figures 1 to 7 As shown, it is the first embodiment of the present utility model. This embodiment provides an automatic cleaning device for the T-block groove of a die head, which includes a first die head 10. One side of the upper end of the first die head 10 is assembled with a second die head 11. A solvent flow channel 12 and a plurality of liquid inlet holes 13 are opened inside the second die head 11, and the solvent flow channel 12 and the plurality of liquid inlet holes 13 communicate with each other. A plurality of T-shaped blocks 14 are assembled inside the solvent flow channel 12. One end of the second die head 11 is provided with a liquid outlet hole 15, and the solvent flow channel 12 and the liquid outlet hole 15 communicate with each other. It further includes:

[0042] A cleaning mechanism 20, which includes a sealing cover 21, a vacuum generator 22 and a pump body 23. The sealing cover 21 is detachably assembled on one side of the second die head 11. After the sealing cover 21 and the second die head 11 are fitted together, a sealed cleaning cavity is formed inside the sealing cover 21, and the sealing cover 21 is adapted to the T-shaped block 14. The vacuum generator 22 is fixed on the upper end of the sealing cover 21. A plurality of reflux sleeves 24 are opened at the lower end of the sealing cover 21. The pump body 23 is arranged at one end outside the first die head 10. The output end of the pump body 23 and the liquid inlet hole 13 are connected by a cleaning hose 25;

[0043] A storage mechanism 30, which is arranged between the sealing cover 21 and the pump body 23. The storage mechanism 30 is connected to the liquid outlet hole 15, the input end of the storage mechanism 30 and the pump body 23, and the storage mechanism 30 and the reflux sleeve 24 by reflux hoses 26 respectively. A circulation path is formed among the pump body 23, the cleaning hose 25, the liquid inlet hole 13, the solvent flow channel 12, the liquid outlet hole 15, the sealing cover 21, the reflux hose 26 and the storage mechanism 30;

[0044] Wherein, when the sealing cover 21 and the second die head 11 are fitted together and compressed air is input into the input end of the vacuum generator 22, the inside of the sealing cover 21 is a negative pressure space.

[0045] Here, an air pump module is also used in conjunction with the device. The air pump module is connected to the input end of the vacuum generator 22 and between the air pump module and the pump body 23 through air pipes. The air pump module can deliver compressed air into the vacuum generator 22.

[0046] In this embodiment, when it is necessary to clean the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14, the sealing cover 21 is attached to one side of the second die head 11 so that the sealing cover 21 corresponds to the T-shaped block 14. The air pump module is started, and compressed air is delivered to the vacuum generator 22 through the air pump module, so that a negative pressure space is formed inside the sealing cover 21 and it closely adheres to the surface of the second die head 11. A cleaning solvent is injected into the storage mechanism 30, and the pump body 23 is started. The cleaning solvent inside the storage mechanism 30 is pumped through the pump body 23, so that the cleaning solvent flows into the solvent flow channel 12 through the pump body 23, the cleaning hose 25 and the liquid inlet hole 13 in sequence, and the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14 is cleaned. The cleaned solvent flows through the liquid outlet hole 15 and the reflux sleeve 24 to the reflux hose 26 and returns to the storage mechanism 30 through the reflux hose 26. The storage mechanism 30 filters the refluxed cleaning solution and flows to the pump body 23 again. During this process, the cleaning solvent can clean the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14, and by delivering compressed air into the vacuum generator 22 through the air pump module, the air pressure inside the sealing cover 21 can be reduced, and thus the waste chips remaining between the multiple T-shaped blocks 14 can be sucked out. During the cleaning process of the second die head 11, there is no need to disassemble and assemble the second die head 11, which improves the cleaning effect and cleaning efficiency. At the same time, by filtering and recycling the refluxed cleaning solvent through the storage mechanism 30, the resource utilization rate can be improved and the maintenance cost can be reduced.

[0047] It should be noted that the inner surface of the T-shaped block 14 refers to the surface that fits with the solvent flow channel 12.

[0048] Secondly, please refer to again Figure 2 and Figure 5 As shown, a pressure regulating hole 16 is opened at one end of the second die head 11 away from the liquid outlet hole 15, and the pressure regulating hole 16 communicates with the solvent flow channel 12. A safety air valve 17 is fixed inside the pressure regulating hole 16. Among them, in the initial state, the safety air valve 17 is in a closed state. When the pressure inside the cleaning chamber is greater than the set value of the safety air valve 17, the safety air valve 17 changes from the closed state to the open state to release the pressure inside the cleaning chamber. When the pressure inside the cleaning chamber is less than the set value of the safety air valve 17, the safety air valve 17 changes from the open state to the closed state.

[0049] Thirdly, please refer to together Figures 4 to 7, check valves 18 are fixed inside multiple liquid inlet holes 13, and the cleaning hose 25 is connected to the liquid inlet holes 13 through the check valves 18.

[0050] Here, the number of check valves 18 connected to the cleaning hose 25 is at least one, and the liquid inlet holes 13 connected to the cleaning hose 25 are in a communicating state, while the liquid inlet holes 13 not connected to the cleaning hose 25 are in a closed state.

[0051] In this embodiment, when cleaning the solvent flow channel 12 and the T-shaped block 14, according to the cleaning requirements, the cleaning hose 25 is connected to several check valves 18. After starting the pump body 23 to convey the cleaning solvent into the solvent flow channel 12, the cleaning solvent flows along the solvent flow channel 12 to the liquid outlet hole 15 and the reflux sleeve 24 respectively to clean the inside of the solvent flow channel 12 and the surface of the T-shaped block 14. Moreover, the other liquid inlet holes 13 not connected to the cleaning hose 25 are in a closed state to prevent the cleaning solvent from flowing out through the inside of the non-connected liquid inlet holes 13.

[0052] Secondly, please refer to again Figure 4 , a sealing ring 27 is fixed at one end of the sealing cover 21 close to the second die head 11, and the material of the sealing ring 27 is rubber.

[0053] In this embodiment, the setting of the sealing ring 27 can improve the sealing performance of the sealing cover 21, prevent the gas outside the sealing cover 21 from flowing into the sealing cavity, and at the same time, can also prevent the cleaning solvent inside the sealing cover 21 from flowing out.

[0054] Please refer to again Figures 8 to 10 As shown, the storage mechanism 30 includes a liquid storage tank body 31, a top cover 32, a driving motor 33, a threaded central rod 34, a partition plate 35, a cross arm 36, a plurality of tension sensors 37, a plurality of linkage rods 38 and a filter plate 39. The liquid storage tank body 31 is arranged at one end of the first die head 10, the top cover 32 is detachably fixed to the upper end of the liquid storage tank body 31, the driving motor 33 is fixed to the upper end of the top cover 32, the threaded central rod 34 is fixed to the output end of the driving motor 33, the lower end of the threaded central rod 34 extends into the interior of the liquid storage tank body 31, and the threaded central rod 34 and the top cover 32 are rotatably connected through a sealing bearing. The partition plate 35 is slidably connected to the interior of the liquid storage tank body 31, and the partition plate 35 and the threaded central rod 34 are rotatably connected through a sealing bearing. The cross arm 36 is threadedly connected to the outside of the threaded central rod 34 and is located above the partition plate 35. A plurality of tension sensors 37 are respectively fixed to the lower ends of both ends of the cross arm 36. A plurality of linkage rods 38 are respectively fixed to the lower ends of the plurality of tension sensors 37, and the linkage rods 38 and the partition plate 35 are slidably connected in a clearance fit manner. The filter plate 39 is fixed to the lower ends of the plurality of linkage rods 38.

[0055] Here, a service terminal is also used in conjunction with the device. The service terminal is electrically connected to the threaded central rod 34 and the tension sensor 37 through wires. The signal obtained by the tension sensor 37 can be transmitted to the service terminal, and the gravity threshold, the forward start time, and the reverse reset time of the threaded central rod 34 can be set through the service terminal.

[0056] Furthermore, the threaded central rod 34 is preferably a servo motor.

[0057] In this embodiment, the pump body 23 drives the cleaning solvent inside the storage mechanism 30 to clean the solvent flow channel 12 and the T-shaped block 14 through the circulation path and then returns to the inside of the liquid storage tank 31 through the return hose 26. After the returned cleaning solvent is filtered by the filter plate 39, large particles of impurities remain on the surface of the filter plate 39. When the cumulative working time of the device is relatively long, the drive motor 33 is started. Due to the fixed connection between the drive motor 33 and the threaded central rod 34, the drive motor 33 drives the threaded central rod 34 to rotate. Due to the threaded connection between the threaded central rod 34 and the cross arm 36, the threaded central rod 34 drives the cross arm 36 to move upward. Since the cross arm 36 is fixedly connected to the tension sensor 37, the tension sensor 37 is fixedly connected to the linkage rod 38, and the linkage rod 38 is fixedly connected to the filter plate 39, the cross arm 36 drives the tension sensor 37, the linkage rod 38, and the filter plate 39 to move synchronously. When the filter plate 39 is separated from the surface of the cleaning solvent, the gravity of the filter plate 39 and the impurities accumulated on its surface can be measured through the tension sensor 37. When the gravity of the filter plate 39 and the impurities on its surface is greater than the gravity threshold, the service terminal can remind the staff to clean the impurities on the surface of the filter plate 39. Finally, the drive motor 33 runs in reverse to drive the filter plate 39 to reset. When the staff cleans the impurities on the surface of the filter plate 39, the top cover 32 is removed from the upper end of the liquid storage tank 31, and then the filter plate 39 is taken out to clean the impurities on the surface of the filter plate 39. Through the above scheme, the staff can clean the surface of the filter plate 39 in time when there are too many impurities accumulated on the surface of the filter plate 39, ensuring the filtering effect and filtering efficiency of the filter plate 39.

[0058] Furthermore, in order to improve the accuracy of the data, after the filter plate 39 is separated from the surface of the cleaning solvent and drained, the gravity of the filter plate 39 and the impurities on its surface is obtained through the tension sensor 37.

[0059] Please refer to again Figures 8 to 10 , a return pipe 301 is provided at the upper end of the outer side of the liquid storage tank 31, and a liquid outlet pipe 302 is provided at the lower end of the outer side of the liquid storage tank 31. During the working state, the filter plate 39 is located between the return pipe 301 and the liquid outlet pipe 302.

[0060] In this embodiment, the filter plate 39 is arranged between the reflux pipe 301 and the liquid outlet pipe 302, which can ensure that the filter plate 39 can filter the refluxed cleaning solvent.

[0061] It should be noted that during the cleaning process of the inside of the solvent flow channel 12 and the surface of the T-shaped block 14, the driving motor 33 will not start. If the filter plate 39 is separated from the liquid level of the cleaning solvent and is located at the lower end of the reflux pipe 301, the flowing reflux cleaning solvent will cause the tension sensor 37 to be unable to obtain accurate gravity data. If the filter plate 39 is separated from the liquid level of the cleaning agent solvent and is located at the upper end of the reflux pipe 301, the filter plate 39 cannot filter the refluxed cleaning solvent.

[0062] Please refer to again Figures 10 to 11 , an annular boss 303 is fixed inside the liquid storage tank body 31, and the annular boss 303 is adapted to the filter plate 39. The material of the annular boss 303 is rubber.

[0063] Here, in the working state, the filter plate 39 and the annular boss 303 are closely attached.

[0064] In this embodiment, when measuring the gravity of the filter plate 39 and the impurities on its surface through the tension sensor 37, the filter plate 39 and the annular boss 303 are separated, and the filter plate 39 and the liquid storage tank body 31 are in an interference fit state, thereby avoiding inaccurate data caused by the contact between the inner wall of the liquid storage tank body 31 and the filter plate 39.

[0065] Please refer to again Figure 9 and Figure 10 As shown, a guiding boss 304 is fixed on the inner wall of the liquid storage tank body 31. The guiding boss 304 is adapted to the partition plate 35, and the partition plate 35 and the liquid storage tank body 31 are slidably connected through the guiding boss 304.

[0066] In this embodiment, when the driving motor 33 drives the threaded central rod 34 to rotate and drives the cross arm 36 to move through the threaded central rod 34, the setting of the guiding boss 304 can prevent the partition plate 35 from rotating synchronously with the threaded central rod 34. At the same time, when disassembling and assembling the filter plate 39, the guiding boss 304 can also guide the partition plate 35.

[0067] The working principle of the present utility model is:

[0068] When it is necessary to clean the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14, attach the sealing cover 21 to one side of the second die head 11 so that the sealing cover 21 corresponds to the T-shaped block 14. Start the air pump module, and send compressed air to the vacuum generator 22 through the air pump module, so that a negative pressure space is formed inside the sealing cover 21 and it closely adheres to the surface of the second die head 11. Inject the cleaning solvent into the storage mechanism 30, start the pump body 23, and extract the cleaning solvent inside the storage mechanism 30 through the pump body 23, so that the cleaning solvent flows into the solvent flow channel 12 in sequence through the pump body 23, the cleaning hose 25 and the liquid inlet hole 13, and clean the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14. The cleaned solvent flows through the liquid outlet hole 15 and the reflux sleeve 24 to the reflux hose 26, and returns to the storage mechanism 30 through the reflux hose 26. The storage mechanism 30 filters the refluxed cleaning solution and then flows to the pump body 23 again. During this process, the cleaning solvent can clean the dirt inside the solvent flow channel 12 and the inner surface of the T-shaped block 14. Moreover, by sending compressed air to the vacuum generator 22 through the air pump module, the air pressure inside the sealing cover 21 can be reduced, and thus the waste chips remaining between the plurality of T-shaped blocks 14 can be sucked out. Set the start time, reset time and gravity threshold of the drive motor 33 through the service terminal, start the drive motor 33, and drive the cross arm 36, the tension sensor 37, the linkage rod 38 and the filter plate 39 to move upward synchronously through the drive motor 33. When the filter plate 39 is separated from the liquid level of the cleaning solvent and the filter plate 39 is drained, obtain the gravity of the filter plate 39 and the impurities on its surface through the tension sensor 37. When the gravity of the filter plate 39 and the impurities on its surface is greater than the gravity threshold, the service terminal can remind the staff to clean the filter plate 39, thereby ensuring the filtering effect and filtering efficiency of the filter plate 39.

[0069] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
