Description

Technical Field

[0001] The present invention relates to the technical field of ink raw material processing devices, and particularly relates to an ink raw material pretreatment device. Background Art

[0002] Ink is a homogeneous mixture composed of coloring substances (such as pigments, dyes, etc.), binders, fillers, additives, etc.; it can be used for printing and dries on the printed object; printing ink pigments are solid powdery substances that are neither soluble in water nor in oil or binders and have a certain color. It is not only the main solid component in the ink but also the visible colored part printed on any object. To a great extent, it determines the quality of the ink, such as color (hue), thickness, etc. It has a great influence on the viscosity, physical and chemical properties, printing properties, etc. of the ink.

[0003] Ink pretreatment is to add ink raw materials (coloring substances, binders, fillers, solvents, etc.) to the device for stirring and mixing, grinding and dispersing, and filtering. The quality of pretreatment will affect the efficiency of subsequent processing and the quality of the ink, such as affecting the uniformity and fineness of the ink. In view of the above problems, existing ink pretreatment devices generally use a mixing cylinder with a stirrer for mixing, which is difficult to uniformly mix various raw materials. Especially for some raw materials with relatively high viscosity, they are prone to adhere together to form small agglomerates, affecting subsequent production and processing. The present invention provides a solution to the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an ink raw material pretreatment device.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions:

An inner lining sleeve made of flexible material is arranged inside the outer cylinder. A plurality of vibration blocks made of stainless steel material are arranged on the inner lining sleeve. The plurality of vibration blocks are arranged in multiple layers, and the vibration blocks in adjacent two layers are arranged in a staggered manner. An amplitude modulation mechanism is installed outside each vibration block. An adjustment hole for the amplitude modulation mechanism to pass through is arranged on the outer cylinder outside each vibration block. The stirrer comprises a stirring shaft, stirring rods and stirring blades. The stirring shaft is in transmission connection with the motor. One end of the stirring rod is connected with the stirring shaft, and the other end is connected with the stirring blade. The stirring blade is in a "Y" - shaped structure, and a strong magnetic structure is installed at each end of the two forks of the "Y" - shaped stirring blade. The stirring rods are arranged in multiple layers on the stirring shaft, and the stirring layers formed by the stirring rods are arranged in a staggered manner with the vibration layers formed by the vibration blocks. The stirring rods on adjacent stirring layers are arranged in a staggered manner. A pulsation mechanism is arranged at the bottom of the outer cylinder.

[0007] Further, the pulsation mechanism comprises a spiral abutting plate, an abutting rod, a pulsation seat, a connecting rod, a pulsation spring and a connecting block. The spiral abutting plate is arranged at the bottom end of the stirring shaft, and the spiral abutting plate is arranged in a circle on the stirring shaft. The pulsation seat is in a frustum - shaped structure, and the bottom of the pulsation seat is open. The discharge outlet is located at the bottom of the pulsation seat. The filter screen above the discharge outlet is also set in a frustum - shaped structure. The pulsation seat covers the outside of the filter screen. The abutting rod is arranged at the top of the pulsation seat, and the upper end of the abutting rod abuts against the spiral abutting plate. One ends of multiple connecting rods are fixedly connected with the outer side wall of the pulsation seat, and the other end of each connecting rod is respectively fixedly connected with a connecting block. The upper and lower ends of the pulsation spring are respectively fixedly connected with the bottom of a connecting block and the bottom of the inner cavity of the outer cylinder.

[0008] Further, the amplitude modulation mechanism comprises an amplitude modulation rod and an amplitude modulation block. One end of the amplitude modulation rod is fixedly connected with the vibration block. The amplitude modulation block is sleeved on the amplitude modulation rod. A positioning groove is arranged on the side wall of the amplitude modulation block. A locking spring and a locking ball are installed inside the positioning groove. The outer end of the positioning groove is installed with a pressing screw block through a threaded structure. A plurality of rows of limit card slots are arranged along the length direction of the side wall of the amplitude modulation rod. The limit card slots are spherical slots, and the depth thereof is less than the radius of the locking ball. The locking spring pushes the locking ball into the limit card slot for positioning.

[0009] Further, the cross - section of the amplitude modulation rod is in a square structure, and the limit card slots are arranged on both sides of the amplitude modulation rod.

[0010] Further, the strong magnetic structure includes a mounting base, a pressing plate, and strong magnetic sheets. The mounting base is arranged at the end of the stirring blade.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. By arranging a strong magnetic structure on the stirring blade, when the stirring shaft rotates, intermittent magnetic suction force is generated between it and the vibration block on the inner lining sleeve, so that the vibration block generates vibration, and the amplitude can be adjusted through the amplitude modulation mechanism. Through the distribution design of the vibration block and the stirring blade, the vibration frequencies of the vibration blocks in different layers can be different. Through a variety of combinations of different frequencies and amplitudes of vibration, the ink raw materials are processed to disperse the raw materials bonded together.

[0018] 2. By designing the pulsating mechanism, when the pulsating seat and the filter screen are quickly separated, a negative pressure will be formed between the two, sucking the material into the space between them. Due to the rapid formation of the negative pressure, cavitation will occur to the entering material, generating small bubbles. When it slowly returns to normal pressure, these bubbles will burst, so as to achieve the purpose of material dispersion. The process of rapid formation of the negative pressure will play a role in dredging the filter screen. Brief Description of the Drawings

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Such as Figure 1-7As shown in the figure, an ink raw material pretreatment device includes an outer cylinder 1, a motor 2, a feed inlet 3, a discharge outlet 4, feet 5 and a stirrer. The motor 2 and the feed inlet 3 are arranged at the top of the outer cylinder 1. The discharge outlet 4 and the feet 5 are arranged at the bottom of the outer cylinder 1. A valve 21 is installed on the discharge outlet 4. The stirrer is installed inside the outer cylinder 1 and is in transmission connection with the motor 2. A lining sleeve 9 made of flexible material is arranged inside the outer cylinder 1. A plurality of vibration blocks 7 made of stainless steel material are arranged on the lining sleeve 9. The plurality of vibration blocks 7 are arranged in multiple layers, and the vibration blocks 7 in adjacent layers are arranged in a staggered manner. An amplitude modulation mechanism 8 is installed outside each vibration block 7. An adjustment hole 6 for the amplitude modulation mechanism 8 to pass through is arranged on the outer cylinder 1 outside each vibration block 7. The stirrer includes a stirring shaft 10, stirring rods 11 and stirring blades 12. The stirring shaft 10 is in transmission connection with the motor 2. One end of the stirring rod 11 is connected to the stirring shaft 10, and the other end is connected to the stirring blade 12. The stirring blade 12 is in a "Y" - shaped structure, and a strong magnetic structure 13 is installed at each of the two forked ends of the Y - shaped stirring blade 12. The stirring rods 11 are arranged in multiple layers on the stirring shaft 10. The stirring layers formed by the stirring rods 11 are arranged in a staggered manner with the vibration layers formed by the vibration blocks 7. The stirring rods 11 on adjacent stirring layers are arranged in a staggered manner. A pulsation mechanism is arranged at the bottom of the outer cylinder 1. The pulsation mechanism realizes reciprocating up - and - down movement, and its rising speed is much greater than its falling speed. Preferably, the number of stirring rods 11 in different stirring layers is set differently, and the number of stirring layers is one less than the number of vibration layers, so as to form different vibration frequencies in different layers.

[0029] Further, as Figure 3 and Figure 4 shown, the pulsation mechanism includes a spiral abutting plate 14, a abutting rod 15, a pulsation seat 16, a connecting rod 18, a pulsation spring 19 and a connecting block 20. The spiral abutting plate 14 is arranged at the bottom end of the stirring shaft 10. The spiral abutting plate 14 is arranged in a circle on the stirring shaft 10. The pulsation seat 16 is in a frustum - shaped structure, and the bottom of the pulsation seat 16 is open. The discharge outlet 4 is located at the bottom of the pulsation seat 16. The filter screen 17 above the discharge outlet 4 is also set in a frustum - shaped structure. The pulsation seat 16 covers the outside of the filter screen 17. The abutting rod 15 is arranged at the top of the pulsation seat 16, and the upper end of the abutting rod 15 abuts against the spiral abutting plate 14. One end of multiple connecting rods 18 is fixedly connected to the outer side wall of the pulsation seat 16, and the other end of each connecting rod 18 is respectively fixedly connected to a connecting block 20. The upper and lower ends of the pulsation spring 19 are respectively fixedly connected to the bottom of a connecting block 20 and the bottom of the inner cavity of the outer cylinder 1.

[0030] Further, as Figure 5 and Figure 6As shown, the amplitude modulation mechanism 8 includes an amplitude modulation rod 22 and an amplitude modulation block 24. One end of the amplitude modulation rod 22 is fixedly connected to the vibration block 7. The amplitude modulation block 24 is sleeved on the amplitude modulation rod 22. A positioning groove 26 is provided on the side wall of the amplitude modulation block 24. A locking spring 28 and a locking ball 29 are installed inside the positioning groove 26. A pressing screw block 27 is installed at the outer end of the positioning groove 26 through a threaded structure. A plurality of rows of limit card slots 23 are arranged along the length direction on the side wall of the amplitude modulation rod 22. The limit card slots 23 are spherical grooves, and their depth is set to be less than the radius of the locking ball 29. The locking spring 28 pushes the locking ball 29 into the limit card slot 23 for positioning.

[0031] Further, as Figure 6 shown, the cross-section of the amplitude modulation rod 22 is of a square structure. The limit card slots 23 are arranged on both sides of the amplitude modulation rod 22. The square structure design can play a guiding role for the amplitude modulation block 24 to prevent it from rotating and being unable to align with the limit card slots 23.

[0032] Further, as Figure 7 shown, the strong magnetic structure 13 includes a mounting base 30, a pressing plate 31 and a strong magnetic sheet 32. The mounting base 30 is arranged at the end of the stirring blade 12. The pressing plate 31 presses a plurality of stacked strong magnetic sheets 32 into the mounting groove of the mounting base 30 and is fixed by a fixing bolt 34 passing through the counterbore on the pressing plate 31 and cooperating with the screw hole 33 on the mounting base 30. Installed by the above structure, it is convenient to replace the strong magnetic sheet 32.

[0033] Further, the outer cylinder 1 is made of stainless steel material, and the inner lining sleeve 9 is made of polytetrafluoroethylene material. Polytetrafluoroethylene has good flexibility and small adhesiveness, reducing the adhesion of raw materials to the wall.

[0034] Further, the number of the feed inlets 3 is multiple. The multiple feed inlets 3 are arranged on the top of the outer cylinder 1 and outside the motor 2. Different raw materials can be added through the multiple feed inlets 3, which is convenient for the proportioning addition of different raw materials.

[0035] Further, the vibration block 7 is arranged in a circular structure. The circular structure design can evenly disperse the vibration force and the inner lining sleeve 9, avoiding the occurrence of concentrated stress.

[0036] Further, a limit plate 25 is provided at the outer end of the amplitude modulation rod 22. The limit plate 25 can prevent the amplitude modulation block 24 from falling off the amplitude modulation rod 22.

[0037] Further, the strong magnetic sheet 32 is made of neodymium iron boron material. Making the strong magnetic sheet 32 of neodymium iron boron not only forms a strong magnetic field intensity, but also has permanent magnetism, avoiding the loss of its magnetism.

[0038] Working principle: Add the ink raw materials into the device from the feed port 3. Pre-adjust the amplitude adjustment blocks 24 on different vibration blocks 7 so that their different positions reach the preset amplitude during operation. Start the motor 2, and the motor 2 drives the stirrer to rotate. The magnetic field generated by the strong magnetic structure 13 at the end of the stirring blade 12 will adsorb the vibration block 7, causing it to vibrate, and the vibration frequency can be controlled by the rotational speed. The pulse seat 16 of the pulse mechanism makes intermittent pulse movements under the action of the abutting rod 15, the spiral abutting plate 14, and the pulse spring 19. During the above rapid process, a rapid negative pressure will be formed between the pulse seat 16 and the filter screen 17. The rapid negative pressure will cause cavitation of the material, achieving a good dispersion effect on the agglomerated material, combined with vibrations of various different amplitudes and frequencies, so as to rapidly disperse the mixed material.

[0039] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
