Description

Technical Field

[0001] This utility model relates to a material preparation mechanism and an ink grinding machine. Background Technology

[0002] In the ink production process, ink grinding is a crucial step to ensure its fineness and uniformity. Traditional ink grinding machines typically employ a roller structure with fixed trapezoidal troughs between the rollers to hold the ink to be ground. However, existing technology has the following problems:

[0003] Incomplete bubble removal: Since manual scraping is an intermittent operation, it is impossible to continuously remove bubbles from the surface and inside of the ink, resulting in residual bubbles in the finished ink, which affects its printing performance and stability; Inconvenient operation: Traditional scrapers need to be picked up and put in separately, and repeated entry and exit from the material trough are required during operation, which can easily interfere with the grinding process. Moreover, it is difficult to keep the scraping force and angle consistent, which affects the uniform distribution of ink.

[0004] To address the aforementioned issues, this invention proposes an improved material preparation mechanism and ink grinding machine. By installing a manually movable scraper on the material trough, operators can more conveniently and continuously scrape the ink, thereby improving material spreading efficiency and air bubble removal. Utility Model Content

[0005] This invention provides a material preparation mechanism and an ink grinding machine, which can effectively solve the above problems.

[0006] This utility model is implemented as follows:

[0007] A material preparation mechanism and an ink grinding machine, comprising a grinding equipment body on which a roller is disposed;

[0008] A material discharge device is located above the main body of the grinding equipment;

[0009] A material straightening assembly is disposed between the two rollers, and the material straightening assembly includes a trapezoidal material trough formed by a side plate, a front inclined plate and an assembly plate;

[0010] The slide rail is arranged laterally along the inclined surface of the front inclined plate;

[0011] The first and second sliders are symmetrically arranged and slidably mounted on the slide rail. The top of the first slider and the second slider are respectively provided with upper clamping brackets, and the front end face is provided with a buffer support plate. The buffer support plate forms a clamping groove with the first slider and the second slider. The clamping groove slides in cooperation with the edge of the front inclined plate.

[0012] The scraper is fixed at both ends to the upper clamping brackets of the first slider and the second slider, and the bottom of the scraper forms an acute angle of 5° to 10° with the inclined surface of the front inclined plate.

[0013] A pre-tightening mechanism, disposed between the two upper clamping brackets, is used to apply a pre-tightening force toward the front inclined plate to the scraper.

[0014] The beneficial effects of this utility model are:

[0015] (1) The material preparation mechanism and ink grinding machine of this utility model achieves efficient material preparation in the ink grinding process by setting a trapezoidal material trough formed by the side plate, the front inclined plate and the assembly plate, and cooperating with the slide rail and symmetrical slider mechanism arranged laterally along the inclined surface of the front inclined plate. The first slider and the second slider arranged symmetrically are fixed to the scraper by the upper clamping bracket, and the bottom of the scraper forms an acute angle of 5° to 10° with the front inclined plate, so that the ink can be evenly spread and effectively remove air bubbles during grinding. The clamping groove formed between the buffer support plate and the slider slides with the edge of the front inclined plate, which not only ensures the stability of the scraper movement, but also absorbs the vibration during the working process. The continuous pressure applied to the scraper by the pre-tightening mechanism ensures that the scraping depth is consistent. The whole set of mechanisms works together to significantly improve the uniformity of ink grinding and the effect of air bubble removal. At the same time, the structure is simple and reliable and easy to operate and maintain. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Reference Figure 1-6 As shown, a material preparation mechanism and an ink grinding machine include a grinding equipment body 10, on which a roller 20 is disposed; and a material pouring device 30 disposed above the grinding equipment body 10.

[0031] The material preparation assembly 40 is disposed between the two rollers 20. The material preparation assembly 40 includes a trapezoidal material trough formed by the side plate 400, the front inclined plate 402 and the assembly plate 404. The assembly plate 404 has an assembly groove 406 for assembling with the front inclined plate 402.

[0032] The slide rail 50 is arranged laterally along the inclined surface of the front inclined plate 402; the bottom of the slide rail 50 is symmetrically provided with adjusting rods 500, and the adjusting rods 500 are provided with pin grooves 502. The front inclined plate 402 is provided with positioning holes corresponding to the pin grooves 502. The pin 504 passes through the pin grooves 502 and the positioning holes in sequence to fix the slide rail 50.

[0033] The first slider 60 and the second slider 60-0 are symmetrically arranged and slidably mounted on the slide rail 50. The top of the first slider 60 and the second slider 60-0 are respectively provided with an upper clamping bracket 602, and the front end is provided with a buffer support plate 612. The buffer support plate 612 forms a clamping groove 614 between the first slider 60 and the second slider 60-0. The clamping groove 614 slides with the edge of the front inclined plate 402. The upper clamping bracket 602 is fixedly connected to the first slider 60 and the second slider 60-0 by bolts 604.

[0034] Specifically, the buffer support plate 612 adopts a three-layer composite structure: the outer layer is a 1.5mm thick stainless steel plate (contact surface), the middle layer is a 3mm thick polyurethane buffer pad (hardness Shore A 60), and the inner layer is fitted into the front inclined plate 402. Meanwhile, the clamping groove 614 is designed with a progressively narrowing structure, with an inlet width of 15mm, a bottom width of 12mm, and a depth of 8mm, forming a 5° guide slope. Furthermore, a PTFE wear-resistant strip (2mm thick) is inlaid on the inner side of the clamping groove 614, forming a sliding pair with the edge of the front inclined plate 402, with a friction coefficient <0.1. Therefore, when the scraper 80 encounters ink clumps, the polyurethane middle layer can be compressed by 0.5-1.2mm, absorbing the instantaneous impact. The elastic deformation of the buffer support plate 612 and the pre-tension spring 6186 form a dynamic balance, controlling the pressure fluctuation range of the scraper 80 within ±5%.

[0035] The first slider 60 and the second slider 60-0 are provided with handles 606 on their front sides for manually driving the first slider 60 and the second slider 60-0 to slide along the slide rail 50.

[0036] The buffer support plate 612 is provided with a screw 608, and the end of the scraper 80 is provided with a threaded hole 6100 that is adapted to the screw 608. The scraper 80 is fixed by screwing the screw 608.

[0037] The scraper 80 is fixed at both ends to the upper clamping brackets 602 of the first slider 60 and the second slider 60-0, respectively. The bottom of the scraper 80 forms an acute angle of 5° to 10° with the inclined surface of the front inclined plate 402. Specifically, this inclination angle causes the scraper to form a "shovel-in" scraping trajectory, which can more effectively agitate the ink and break the surface tension of air bubbles compared to parallel scraping. The 5° to 10° inclination angle generates a downward force during scraping, which ensures that the ink is evenly spread to both sides and avoids ink splashing due to excessive angle. The bottom of the scraper 80 is provided with an elastic scraper strip, which is made of polyurethane or rubber. Furthermore, a replaceable elastic scraper strip is embedded in the bottom of the scraper 80. The strip has a rectangular or trapezoidal cross section, a thickness of 3-5mm, and is made of polyurethane (hardness Shore A 70-90) or wear-resistant rubber (such as NBR). It is fixed to the scraper body by a slot or bolt. The surface unevenness of the front inclined plate 402 can be compensated by the elastic material to ensure full-width contact (fit > 95%), while avoiding direct contact between the metal scraper and the ink in the roller area, and preventing hard impurities from being crushed and damaged on the roller surface.

[0038] The bottom of the scraper 80 is serrated or wavy. Specifically, the cutting edge adopts a continuous serrated shape (tooth pitch 5-8mm, tooth depth 1-2mm) or a sinusoidal wavy shape (wavelength 10-15mm, wave height 2-3mm), with a chamfered edge (R0.2-R0.5), and is integrally formed with the elastic scraper or assembled separately. Furthermore, the special cutting edge generates local vortices during movement, causing micro-circulation of deep ink, improving bubble escape efficiency by more than 40%, and the wavy cutting edge generates periodic shearing force on the ink, promoting pigment dispersion. Tests have shown that this can shorten grinding time by 15%-20%. Moreover, the discontinuous cutting edge design reduces ink adhesion, and combined with the self-cleaning properties of the elastic material, reduces the frequency of downtime for cleaning.

[0039] A pre-tightening mechanism, disposed between two upper clamping brackets 602, is used to apply a pre-tightening force to the scraper 80 toward the front inclined plate 402. The pre-tightening mechanism includes a pre-tightening bracket 618, a positioning plate 6180 fixed to the end of the pre-tightening bracket 618, a pre-tightening cylinder 6182 sleeved on the positioning plate 6180, a pre-tightening rod 6184 passing through the pre-tightening cylinder 6182, and a pre-tightening spring 6186 disposed inside the pre-tightening cylinder 6182 and abutting against the pre-tightening rod 6184. An adjusting nut is provided at the end of the pre-tightening rod 6184 for manually adjusting the compression of the pre-tightening spring 6186.

[0040] Furthermore, as one embodiment of this case, a preferred embodiment of the ink grinding machine employs an electrically driven structure to move the scraper, and its specific working process is as follows:

[0041] S1. A servo motor is installed at one end of the slide rail 50. The output shaft of the servo motor is connected to the ball screw through a coupling. The screw nut is rigidly connected to the first slider 60 and the second slider 60-0.

[0042] S2. The control system, such as PLC or speed controller, starts the servo motor, drives the ball screw to rotate, and causes the screw nut to drive the first slider 60 and the second slider 60-0 to move laterally and reciprocally along the slide rail 50.

[0043] S3. The scraper 80 moves at a constant speed under the drive of the motor. Its bottom sawtooth / wave-shaped structure, together with the elastic scraper strip made of polyurethane or rubber, scrapes the ink flat.

[0044] S4. Because the scraper 80 and the front inclined plate 402 form an angle of 5° to 10°, the ink is slightly agitated during the scraping process, which effectively breaks and removes surface and internal air bubbles.

[0045] S5. The pre-tightening mechanism, including the pre-tightening spring 6186 and the adjustable nut, continuously applies pressure to the scraper 80 toward the front inclined plate 402 to ensure stable contact force during scraping. If the ink viscosity is too high, causing increased resistance, the servo motor 70 can automatically adjust the speed or torque to avoid overload.

[0046] S6 and slide rail 50 are equipped with limit sensors at both ends. When the slider moves to the limit position, the motor automatically reverses, realizing the reciprocating motion of scraper 80. Users can set the scraper 80's moving speed, stroke range, and dwell time through the control panel to adapt to the grinding needs of different ink formulations.

[0047] S7. The angle of the scraper 80 can be finely adjusted by adjusting the screw 608 to optimize the scraping effect; the slide rail 50 still retains the quick-release structure of the pin 504, which is convenient for cleaning or replacing the scraper 80.

[0048] Working principle:

[0049] The ink is continuously injected into the trapezoidal trough formed by the side plate 400, the front inclined plate 402, and the assembly plate 404 through the pouring device 30. Grinding is performed under the shearing force generated by the relative rotation of the rollers 20. The operator manually drives the first slider 60 and the second slider 60-0 to reciprocate laterally along the slide rail 50 via the handle 606, causing the scraper 80 to move regularly on the inclined surface of the front inclined plate 402. The bottom of the scraper 80 maintains an acute angle of 5° to 10° with the inclined surface. Its specially designed saw... The toothed or wavy structure, combined with the elastic scraper made of polyurethane / rubber, effectively removes surface air bubbles from the ink under the continuous pressure provided by the pre-tightening mechanism (including the pre-tightening spring 6186, pre-tightening rod 6184, and adjustable nut). The wavy blade also generates turbulence to break up internal air bubbles. The slide rail 50 is quickly positioned and installed through the cooperation of the adjusting rod 500, pin groove 502, and pin 504. The upper clamping bracket 602 is fixed by bolts 604, forming a stable motion mechanism. The entire system, through the synergy of mechanical pre-tightening and manual adjustment, achieves both air bubble removal and uniform spreading during ink grinding, significantly improving ink grinding quality and efficiency while ensuring ease of operation.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
