[0033] The plurality of saw blade 7 is equidistantly arranged on the water-cooled pipe 4.

[0034] The filter screen 8 is movably arranged in the crushing box 1 and below the saw blade 7.

[0035] The jacket 9 is circumferentially fixed on the outer wall of the crushing box 1, and the jacket 9 is communicated with the water inlet pipe and the water outlet pipe (the water inlet pipe and the water outlet pipe are not shown in the figure).

[0036] The first mounting frame 10 and the second mounting frame 12 are fixed on the two sides of the crushing box 1 respectively.

[0037] The water supply assembly and the gear transmission assembly 11 are fixed on the first mounting frame 10, the gear transmission assembly 11 is connected with the water-cooled pipe 4, and the water supply assembly is communicated with the first rotary joint 5 and the water inlet pipe respectively.

[0038] The collecting box 13 and the suction pump 14 are fixed on the second mounting frame 12, and the suction pump 14, the second rotary joint 6 and the water outlet pipe are communicated with the collecting box 13 respectively.

[0039] In order to make the printing paste can fully contact with the saw blade 7 to complete the crushing, the further refinement of the scheme is as follows: Figure 2 As shown in the figure, the crushing box 1 is symmetrically provided with the mounting plate 15 in the inside, the mounting plate 15 is provided with a plurality of springs 16, one end of the spring 16 is connected with the filter screen 8, the two sides of the filter screen 8 are slidably connected with the slide rails 17 fixed on the inner wall of the crushing box 1 symmetrically, and the upper end of the slide rail 17 is fixed with a limiting plate, and the limiting plate is not shown in the figure.

[0040] The further refinement of the embodiment scheme of the utility model is as follows: Figure 1 As shown in the figure, the water supply assembly comprises a cold water pump 18, a cold water tank and a three-way pipe 19, the cold water pump 18 is fixed on the first mounting frame 10, the input end of the cold water pump 18 is communicated with the cold water tank (the cold water tank is not shown in the figure), the output end of the cold water pump 18 is communicated with the three-way pipe 19, and the remaining two pipes of the three-way pipe 19 are communicated with the water inlet pipe and the first rotary joint 5 respectively.

[0041] In order to avoid the water in the collecting box 13 from overflowing after being collected, the further optimization of the scheme is that an ultrasonic liquid level sensor is arranged in the collecting box 13, and the ultrasonic liquid level sensor is not shown in the figure.

[0042] In order to improve the crushing effect on the printing paste, the further optimization of the scheme is as follows: Figure 1As shown, several groups of sawtooth blades 7 are equidistantly arranged on the water-cooled pipe 4 and inside the crushing box 1, and the sawtooth blades 7 in each group are circumferentially distributed about the water-cooled pipe 4.

[0043] It should be noted that the gear transmission assembly 11, the cold water pump 18, the suction pump 14 and the ultrasonic liquid level sensor are electrically connected with the controller, and the controller is not labeled in the figure.

[0044] The working process of the utility model is as follows:

[0045] Firstly, the printing paste is added into the crushing box 1 from the feeding hopper 2, and the amount of the printing paste added at one time is pre-calculated, so that the probability of the filter screen 8 being blocked due to too much material can be reduced. The printing paste is added at the same time, and the gear transmission assembly 11 is controlled to work by the controller, so as to drive the water-cooled pipe 4 to rotate at high speed. At this time, the several groups of sawtooth blades 7 arranged on the water-cooled pipe 4 can be in contact with the blocky printing paste, so as to scatter the blocky material into powder. The printing paste with a particle size smaller than the filter hole of the filter screen 8 after crushing can pass through the filter screen 8 and be discharged from the discharge pipe 3. The printing paste with a particle size larger than the filter hole of the filter screen 8 will fall on the filter screen 8. At this time, the spring 16 is compressed, and when the spring 16 restores to reset, the printing paste with a large particle size can be in contact with the sawtooth blades 7 again and be fully crushed (it should be noted that the movement range of the filter screen 8 is pre-set, so that the filter screen 8 will not be in contact with the sawtooth blades 7). Finally, all the printing paste can be crushed and discharged.

[0046] In the crushing process, due to the intense friction and shearing action between the high-speed rotating sawtooth blades 7 and the paste particles, mechanical energy is converted into heat energy, so that the temperature of the crushing cavity rises rapidly. At this time, the cold water pump 18 is controlled to work by the controller, so as to inject cold water into the jacket 9 and the water-cooled pipe 4. At this time, most of the heat generated in the crushing process can be effectively removed, so as to avoid the breakage or denaturation of the molecular chain of the paste containing heat-sensitive components due to the high temperature in the crushing box 1, and to reduce the rheological properties of the paste and the color development effect after printing.

[0047] After the cold water in the water-cooled pipe 4 and the jacket 9 removes the heat in the crushing box 1, the water is injected into the collection box 13. When the ultrasonic liquid level sensor detects that the water level in the collection box 13 exceeds the pre-set upper limit value, a feedback signal is sent to the controller. The controller controls the operation of the suction pump 14, so as to remove the water. The water can be reused after being cooled by heat exchange.

[0048] In order to reduce the invalid circulation of the printing paste in the crushing cavity, in some embodiments, each group of sawtooth blades 7 includes coarse sawtooth blades 7, medium sawtooth blades 7 and fine sawtooth blades 7, which are not shown in the figure; the coarse teeth in this embodiment are responsible for the preliminary crushing of the paste block, and the fine teeth complete the fine crushing, which can reduce the invalid circulation of the material in the crushing cavity, and the further optimization of the scheme, the distance between the two adjacent groups of sawtooth is controlled within 3-5mm to avoid the winding of the fiber paste around the shaft.

[0049] In order to further improve the crushing fineness, the root of the sawtooth blade 7 is provided with a spiral blade line, and the base body of the sawtooth blade 7 is made of high chromium alloy steel; the spiral blade line is not shown in the figure; this embodiment generates axial thrust by rotation to forcibly push the printing paste, so that the printing material forms a vortex in the crushing cavity, prolongs the effective crushing time, and the crushing fineness can be improved by 20%, and the wear resistance of the sawtooth blade 7 made of high chromium alloy steel is more than 3 times that of ordinary blades.

[0050] In order to avoid the phenomenon of a large amount of dust during the feeding and discharging of the printing paste into the crushing box 1, in other embodiments, as shown in Figure 2

[0051] Feeding: the feeding hopper 2 is fixedly provided with a blocking plate 20, the blocking plate 20 is connected with the output pipe of the hose pump 21, and the hose pump 21 is connected with the dry printing paste box (the dry printing paste box is not shown in the figure);

[0052] Discharging: the leg of the crushing box 1 is placed with a powder collecting box 22, the powder collecting box 22 is provided with a feeding port (not shown in the figure), the outer side of the discharge pipe 3 is threadedly connected with an extension pipe 23 matched with the diameter of the feeding port, and the extension pipe 23 extends to the inside of the powder collecting box 22 through the feeding port;

[0053] Further optimization of the above-mentioned embodiment scheme, as shown in Figure 2 The side of the powder collecting box 22 is fixedly provided with a powder conveying pump 24 connected with the inside thereof; this embodiment adopts sealed transmission to avoid dust overflow, and the discharge can significantly reduce the amount of dust overflow, and after completing a round of crushing of the printing paste, the printing paste can be automatically conveyed to the next area for subsequent processing by the powder conveying pump 24, without the need for manual transfer and handling of the powder collecting box 22.
