[0020] When the ink buffer mechanism 2 is moved so that it is directly below the nozzle, that is, when the ink buffer mechanism 2 is in position A, the upper surface of the printing ink receiving table 3 corresponds to the nozzle position of the industrial inkjet printer, and pressure can be applied to the ink path of the nozzle to press the ink, or the industrial inkjet printer can be put into a test state.

[0021] Since the ink buffer mechanism 2 is slidably connected to the connection support frame 1, when the connection support frame 1 is connected to the bottom plate 27 of the nozzle module of the industrial inkjet printer, the ink buffer mechanism 2 can be slid to move the ink receiving table 3 away from under the nozzle 28, so as to facilitate wiping the nozzle.

[0028] In order to facilitate the determination of position A and position B, a blocking rod Ⅰ 19 is provided at the front end of the printing ink receiving table 3, and a blocking rod Ⅱ 25 is provided at the rear end. When the ink cache mechanism 2 moves to the point where the blocking rod Ⅰ touches the front bracket Ⅰ, it is position B; when the ink cache mechanism 2 moves to the point where the blocking rod Ⅱ touches the rear bracket Ⅱ, it is position A.

[0029] In order to facilitate the sliding positioning of the ink buffer mechanism 2 and prevent the test ink overflowing from the ink receiving guide surface 17 of the printing ink receiving table from contaminating the front bracket Ⅰ12 and the rear bracket Ⅱ15, the blocking rod Ⅰ is L-shaped, and the upper surface of the side connected to the printing ink receiving table 3 is lower than the upper surface of the printing ink receiving table 3, and the upper surface facing the front bracket Ⅰ12 is higher than the lower surface of the front bracket Ⅰ; the blocking rod Ⅱ is L-shaped, and the upper surface of the side connected to the printing ink receiving table 3 is lower than the upper surface of the printing ink receiving table 3, and the upper surface facing the rear bracket Ⅱ15 is higher than the lower surface of the rear bracket Ⅱ.

[0030] A guide rail 5 is provided on the inner side or the bottom of the connecting support frame 1 , and a corresponding slide rail 11 is provided on the ink buffer mechanism 2 . The connecting support frame 1 and the ink buffer mechanism 2 are slidably connected via the corresponding guide rail and the slide rail 11 .

[0031] When the ink buffer mechanism 2 is moved so that the ink buffer mechanism 2 leaves the nozzle, the end of the ink buffer mechanism 2 is pulled out of the front bracket Ⅰ12, and the position of the connecting support frame 1 directly below the nozzle forms an unobstructed space, and the nozzle can be wiped by reaching in from the position of the connecting support frame 1 directly below the nozzle, wherein a structure of the connecting support frame 1 is as follows: the connecting support frame 1 includes two opposite side plates 31, and the two side plates are respectively provided with guide rails 5 along the length direction of the side plates, the upper front ends of the two side plates 31 are connected by the front bracket Ⅰ12, and the upper rear ends are connected by the rear bracket Ⅱ15, and the upper end 32, the lower end 33, the front end 34, and the rear end 35 of the connecting support frame 1 are respectively open structures; the ink buffer mechanism 2 is provided with a corresponding slide rail 11, and the connecting support frame 1 and the ink buffer mechanism 2 are slidably connected through the corresponding guide rail and the slide rail 11, and the slide rail 11 can slide out of the guide rail 5. Thus, the end of the ink buffer mechanism 2 can be pulled out of the front bracket Ⅰ.

[0032] The guide rail 5 may be a dovetail track guide rail, and the slide rail 11 may be a dovetail track slide rail 11 .

[0033] An installation hole is provided on the upper surface of the connecting support frame 1 for fixing the cylindrical strong magnet 4, and the upper surface of the cylindrical strong magnet 4 is parallel to the upper surface of the connecting support frame 1. Structural adhesive is used to stick 36 cylindrical strong magnets 4 of appropriate sizes flat, so that the upper surface of the connecting support frame 1 fits to the lower surface of the bottom plate of the nozzle module.

[0034] Along the direction of the slide rail 11, a handle 6 is provided on the outer side of one end of the ink buffer mechanism 2, as shown in the present application. Figure 7 A handle 6 is provided on the outer side of the front end of the middle ink buffer mechanism 2 .

[0035] If there is a lot of ink, an ink outlet Ⅰ16 is provided in the ink buffer mechanism 2 to facilitate the discharge of ink.

[0036] In order to achieve the reuse of recovered ink, the ink outlet I16 is connected to the ink inlet I of the power delivery device 22, the ink outlet II of the diaphragm pump 22 is connected to the ink inlet II of the filter 23 through an ink tube, and the ink outlet III of the filter 23 is connected to the ink supply device of the printer's ink supply unit, such as an ink supply barrel, through an ink tube.

[0037] The power delivery device 22 may be a diaphragm pump.

[0038] The filter 23 may be a capsule filter with a precision of 10 microns.

[0039] A magnetic proximity switch 20 is installed on the ink cache mechanism 2, and a PP magnetic float 29 is also provided in the ink cache mechanism 2 to control the on and off of the magnetic proximity switch as the liquid level rises and falls; the input positive pole of the power transmission device 22 is connected to the positive pole of the power supply through the normally open relay 21, and the input negative pole of the power transmission device 22 is connected to the negative pole of the power supply, the positive pole of the input end of the normally open relay 21 is connected to the positive pole of the power supply, and the negative pole of the input end of the normally open relay 21 is connected to the output signal of the magnetic proximity switch 20, the output common end of the normally open relay 21 is connected to the positive pole of the power supply, and the normally open end of the normally open relay 21 is connected to the input positive pole of the power transmission device 22; one end of the line input of the magnetic proximity switch 20 is connected to the negative pole of the power supply, and one end of the line output is connected to the negative pole of the input signal of the normally open relay 21.

[0040] A magnetic switch mounting position 7 is provided on the outside of the ink buffer mechanism 2, and a magnetic proximity switch 20 is installed on the magnetic switch mounting position 7; a PP magnetic float lifting guide groove 9 is provided inside the ink buffer mechanism 2, and a PP magnetic float 29 is provided inside the PP magnetic float lifting guide groove 9; the ink buffer mechanism 2 is provided with an ink buffer groove 30, and the PP magnetic float lifting guide groove 9 is connected with the ink buffer groove 30. As the liquid level in the PP magnetic float placement groove 9 rises, the PP magnetic float 29 floats to a certain height, and the magnetic force of the PP magnetic float causes the magnetic reed inside the magnetic proximity switch 20 to close to form a passage, and the magnetic proximity switch 20 outputs a signal to the normally open relay 21, the normally open relay 21 is closed, and the power transmission device 22 is started, and then the liquid level in the ink buffer groove 30 drops, the liquid level in the PP magnetic float placement groove 9 drops, and the PP magnetic float 29 drops. When the PP magnetic float 29 drops to a certain height, the magnetic proximity switch 20 resumes the open circuit.

[0041] The reed switch in the magnetic proximity switch 20 is arranged horizontally, the two metal reeds in the reed switch are arranged horizontally, the north and south poles of the magnet in the PP magnetic float are in the horizontal direction, the steel nozzle module bottom plate 27 and the cylindrical strong magnet 4 installed on the connecting support frame 1 are at a certain distance from the magnetic proximity switch 20 and the PP magnetic float 29, and due to the setting of the direction of the reed switch in the magnetic proximity switch 20, the direction of the magnetic poles of the magnet in the PP magnetic float, and the direction of the cylindrical magnetic poles of the cylindrical strong magnet 4, the steel nozzle module bottom plate 27 and the cylindrical strong magnet 4 installed on the connecting support frame 1 do not affect the PP magnetic float 29 as the liquid level rises and falls, and the reed switch in the magnetic proximity switch is turned on and off.

[0042] The PP magnetic float lifting guide groove 9 and the ink buffer groove 30 are provided with a connecting hole, and the connecting hole penetrates the ink buffer groove 30 from top to bottom. Figure 7 The PP magnetic float lifting guide groove 9 and the ink buffer groove 30 are separated by a partition, and at least two partitions 90 are provided. There is a gap 91 between the partitions 90. The existence of the gap 91 ensures that when there is liquid in the ink buffer groove 30, the upper surface of the liquid in the ink buffer groove 30 is on the same plane or at the same height as the upper surface of the liquid in the PP magnetic float lifting guide groove 9.

[0043] The liquid in the ink buffer groove 30 flows into the ink buffer groove 30 . As the liquid level in the ink buffer groove 30 rises and falls, the liquid level in the PP magnetic float lifting guide groove 9 also gradually rises, causing the PP magnetic float to move up and down in the PP magnetic float lifting guide groove 9 .

[0044] The magnetic proximity switch 20 is fixed on the magnetic switch mounting position 7 through the magnetic switch mounting screw hole 8. The PP magnetic float lifting guide groove 9 is set corresponding to the magnetic switch mounting position 7 and is located on the inner side of the ink buffer mechanism 2. The upper surface of the magnetic proximity switch 20 can be set to be flush with the upper surface of the ink buffer mechanism 2. When the PP magnetic float 29 rises to a certain height so that the magnetic force connects the two metal reeds inside the magnetic proximity switch 20 together, a passage is closed, and the magnetic proximity switch 20 outputs a signal to the normally open relay 21, triggering the closure of the input signal end of the normally open relay 21, and then the output normally open end of the normally open relay 21 is closed with the common end, so that the power transmission device 22 is started, and the printing ink is drawn out from the ink outlet Ⅰ16 of the printing ink receiving mechanism and filtered through the filter 23 to the ink supply barrel of the printer ink supply unit. This is repeated to achieve the recycling of printing ink.

[0045] The normally open relay 21 is a time-delay relay. When the input signal terminal of the normally open relay 21 changes from closed to open, the normally open relay 21 keeps the output normally open terminal and the common terminal closed, and delays for a certain period of time, so that the power transmission device 22 continues to work. When the delay of the normally open relay 21 ends, the output normally open terminal of the normally open relay 21 is disconnected from the common terminal, and the power transmission device 22 stops working, so that the ink in the ink buffer slot 30 is drained as cleanly as possible, thereby reducing the number of times the power transmission device 22 is started.

[0046] The ink buffer groove 30 is further provided with an ink buffer groove guide channel 10, and the ink buffer groove guide channel 10 is an inclined surface inclined toward the ink outlet of the printing ink receiving mechanism, so as to facilitate the discharge of ink.

[0047] The bottom surface of the PP magnetic float placement groove 9 is lower than the bottom surface of the ink buffer groove. When there is no liquid in the PP magnetic float placement groove 9, the vertical center of the PP magnetic float 29 is flush with the lowest point of the bottom surface of the ink buffer groove, providing a lower installation position for the PP magnetic float 9.

[0048] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. It should be pointed out that for those skilled in the art and any technician familiar with the technical field, without departing from the overall concept of the present invention, the technical solution and the inventive concept of the present invention are equivalently replaced or changed, and several changes and improvements are made, which should also be regarded as the protection scope of the present invention.
