Description

Technical Field

[0001] The utility model relates to the technical field of filtering mechanisms, in particular to an ink filling and filtering device. Background Art

[0002] During the ink processing process, the finished product or the sample in the process needs to be stored and filled. When filling it, a filling machine is usually used to fill the ink into a transparent container for use. There are many sources of ink contamination during production. Due to the complex production, there are various types of impurities, such as fibers, solids and semi-solids, so it is necessary to filter it before filling to remove pollutants.

[0003] A search of Chinese patent publication number CN219279478U discloses an ink filling and filtering device, which includes a support assembly and a filling assembly. The support assembly includes a running part and a transverse moving part, with the transverse moving part being mounted on the running part. During use, a worker rotates and closes a threaded sleeve on the valve side, disengaging the sleeve from the liquid guide tube. The connecting tube can then be removed from the liquid guide tube, allowing impurities on the filter to be cleaned and recovered. After cleaning, the connecting tube is returned to the liquid guide tube through the threaded sleeve, following the reverse steps described above. During daily use, workers can use a motor to quickly move the filling station, allowing the filling station to accommodate multiple ink bottles at a time, and then quickly complete the ink filling operation by moving the filling station. This device ensures the flow of ink through the filter, improving ink filling efficiency. However, this device requires manual monitoring and switching of the filter assembly, and the filter is difficult to process online during the filling and filtration process, resulting in the need for disassembly and cleaning after each short use. This is inconvenient and leaves room for improvement in practicality. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1 — Figure 9As shown, an ink filling and filtering device includes a bottom plate 101, a support assembly 102 is provided on the top of the bottom plate 101, a transverse movement assembly 103 is provided on the bottom plate 101, the transverse movement assembly 103 is used to accommodate multiple ink bottles at a time, and control the transverse movement of the ink bottles to quickly complete the ink filling operation, a liquid storage mechanism is installed on the support assembly 102, the liquid storage mechanism includes a liquid storage tank 201, a filling mechanism is installed on the support assembly 102, the filling mechanism includes a first connecting pipe 301, an electric control valve 204 is fixedly installed at the liquid outlet end at the bottom of the liquid storage tank 201, and the first connecting pipe 301 is connected to the liquid outlet end at the bottom of the liquid storage tank 201. The liquid outlet of the liquid storage tank 201 is connected to the middle position of the liquid storage tank 201. The electronically controlled valve 204 can control the passage state of the liquid outlet of the electronically controlled valve 204 and the passage state of the positions at both ends of the first connecting pipe 301. The two ends of the first connecting pipe 301 are connected to the upper mounting block 302 by bolts. The bottom of the upper mounting block 302 is connected to the second connecting pipe 303 by bolts. The bottom of the second connecting pipe 303 is connected to the lower mounting block 304 by bolts. The inner sides of the two lower mounting blocks 304 are connected to the third connecting pipe 305 by bolts. A filtering mechanism is provided in the second connecting pipe 303, and a detection mechanism is provided in the second connecting pipe 303.

[0031] The filtering mechanism includes a connecting ring 401, and a filter screen 402 is connected to the connecting ring 401 by bolts. The detection mechanism is used to automatically switch the liquid outlet path of the liquid storage tank 201 to another group of filling mechanisms according to the blockage condition of the filter screen 402.

[0032] In this embodiment, the detection mechanism includes a moving cylinder 501, which is slidably connected to the second connecting tube 303 and the inner wall of the lower mounting block 304. A number of snap-in holes 502 are provided on the top of the moving cylinder 501, and a number of spherical snaps 403 are connected to the bottom of the connecting ring 401 by bolts. The spherical snaps 403 are used to fix the connecting ring 401 to the moving cylinder 501.

[0033] In this embodiment, the bottom of the lower mounting block 304 is connected to a mounting box 504 by bolts, and a spring 503 is installed inside the mounting box 504. The spring 503 is connected to the bottom of the moving cylinder 501, and an electromagnet 505 is installed in the mounting box 504. The electromagnet 505 is used to limit the moving cylinder 501 to the liquid inlet position of the third connecting tube 305 when the moving cylinder 501 descends to a certain distance. When the moving cylinder 501 descends to a certain position, the attraction of the electromagnet 505 on the moving cylinder 501 can prevent the spring 503 from resetting. At this time, the moving cylinder 501 blocks the liquid inlet of the third connecting tube 305, indicating that there are too many clogged particles on the filter screen 402 at this time, and it is necessary to switch to another set of filtering mechanisms for filling and filtering, and the staff needs to clean the filter screen 402.

[0034] In this embodiment, a controller 506 is fixedly installed on the outside of the installation box 504, and a pressure sensor is integrated inside the controller 506 for detecting the pressure of the spring 503 on the installation box 504. The controller 506 is electrically connected to the electric control valve 204 for controlling the switching of the liquid outlet path of the liquid storage tank 201. When the electromagnet 505 limits the movable cylinder 501, the movable cylinder 501 compresses the spring 503, and the pressure of the spring 503 on the installation box 504 lasts for a certain period of time. At this time, the controller 506 will control the electric control valve 204 to switch to another path of the first connecting pipe 301, and use another set of filtering mechanisms for filling and filtering.

[0035] In this embodiment, a rotating shaft 404 is rotatably connected to the inner side of the filter screen 402, a connecting sleeve 406 is slidably connected to the rotating shaft 404, a disassembly handle 407 is rotatably connected to the top of the connecting sleeve 406, and a threaded sleeve 408 is connected to the bottom of the disassembly handle 407 by a bolt, and a mounting tube 308 is welded to the top of the upper mounting block 302 for making the threaded sleeve 408 detachable.

[0036] In this embodiment, a scraper 405 is welded to the bottom of the rotating shaft 404. The scraper 405 is used to scrape the clogged particles on the filter 402 until they are accumulated. A guide piece 409 is connected to the disassembly handle 407 by bolts. A guide rod 410 is connected to the top of the rotating shaft 404 by bolts. The guide piece 409 is used to make the guide rod 410 drive the rotating shaft 404 to rotate. When the ink passes through the second connecting pipe 303, the filter 402 is clogged by particles, resulting in an increasing resistance for the ink to pass through the filter 402. The ink passes through the blocked filter. The net 402 will press down the connecting ring 401, and the connecting ring 401 will compress the spring 503 through the moving cylinder 501. The filter 402 will drive the rotating shaft 404 to descend, and the guide rod 410 on the top of the rotating shaft 404 will rotate under the guidance of the guide piece 409, thereby driving the scraper 405 to rotate, scraping the particles on the upper surface of the filter 402 and scraping the particles into a pile state. The greater the descending distance of the filter 402, the larger the scraping area of the scraper 405, thereby extending the single use time of the filter 402 and reducing the frequency of replacement and cleaning.

[0037] In this embodiment, the filling mechanism includes a filling machine body 307, and a filling tube 306 is fixedly connected to the bottom of the third connecting tube 305 and is interconnected. The filling machine body 307 is used to control the filling tube 306 to perform filling work. When the transverse movement component 103 moves the ink bottle, the filling tube 306 is controlled to cooperate according to the movement rhythm of the transverse movement component 103, so as to facilitate rapid filling.

[0038] In this embodiment, a screen 202 is detachably connected to the liquid storage tank 201, and the screen 202 is used to filter out large particles of impurities in the ink. A fixing sleeve 203 is connected to the outside of the liquid storage tank 201 by bolts, and the fixing sleeve 203 is connected to the top position of the support assembly 102 by bolts.

[0039] Working principle: Before using the device, in the initial state, the filling mechanism and the filtering mechanism are in a separated state. The staff moves the disassembly handle 407 to the position above the upper mounting block 302, first aligns the spherical buckle 403 at the bottom of the connecting ring 401 with the snap-on hole 502 and presses down the shaft 404 to lock the spherical buckle 403, rotates the disassembly handle 407, and installs the threaded sleeve 408 on the mounting tube 308. In this way, another set of filtering mechanisms is installed. When filling is started after the installation is completed, the ink to be filled is put into the liquid storage tank 201. The ink first passes through the screen 202 to preliminarily screen out large particles, and then the transverse assembly 103 and the filling assembly are moved horizontally. The installation body 307 starts working. The ink passes through the first connecting pipe 301, the upper mounting block 302, the second connecting pipe 303, the lower mounting block 304 and the third connecting pipe 305. The filter 402 filters the small particles in the ink and then discharges it from the filling pipe 306. The filling work is carried out on multiple ink bottles one by one. As the filling progresses, more and more particles clog the filter 402, and the resistance of the ink flowing through the filter 402 increases. Due to the setting of the movable cylinder 501 and the spring 503, the filter 402 and the connecting ring 401 will receive the reaction force of the resistance and fall. When falling, the filter 402 pulls the rotating shaft 40 4 descends synchronously, and the guide rod 410 on the top of the rotating shaft 404 is pushed by the guide piece 409 to rotate, thereby driving the scraper 405 to rotate through the rotating shaft 404, and the scraper 405 scrapes the particles on the upper surface of the filter 402 to a piled state. The greater the descending distance of the filter 402, the larger the scraping area of the scraper 405, thereby extending the single use time of the filter 402 and reducing the replacement and cleaning frequency. When the accumulation of blocked particles on the filter 402 reaches a certain level, the filter 402 pushes the movable cylinder 501 down to the point where the attraction of the electromagnet 505 on the movable cylinder 501 can prevent the spring 503 from resetting. When the filter element 502 is in the liquid flow, the filter element 503 is turned off, and the filter element 504 is turned off. When the filter element 502 is turned off, the filter element 503 is turned off, and the filter element 502 is turned off. When the filter element 502 is turned off, the filter element 503 is turned off, and the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off. When the filter element 502 is turned off, ..., the filter element 502 is turned off, and the filter element 502 is turned off. When the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off, the filter element 502 is turned off, and the filter element 502 is turned off
