Description

Technical Field

[0001] The utility model belongs to the technical field of coating production equipment, and particularly relates to a multifunctional coating grinding machine. Background Art

[0002] In the coatings production process, grinding and dispersion are key steps that impact the quality of the final product. Traditional coating grinding equipment typically uses simple mechanical grinding methods, using fixed grinding rollers or grinding discs to pulverize the material. However, when processing high-viscosity, easily agglomerated coatings, this type of equipment is prone to problems such as uneven grinding, low efficiency, and incomplete dispersion.

[0003] In addition, the grinding discs of existing equipment are usually arranged in parallel, and the material has a single path during the grinding process, which cannot fully achieve multi-angle and multi-directional shearing and grinding, resulting in poor material refinement processing effects. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a multifunctional paint grinder, which can improve the complex path and shearing times of the material during the grinding process, thereby improving the grinding effect and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A multifunctional paint grinder comprises a frame, a motor is provided at the inner bottom of the frame, a linkage mechanism is provided at one end of the upper portion of the frame, grinding rollers are rotatably connected to the top of the frame at equal intervals along the length direction, the number of the grinding rollers is set to three, and grinding discs are provided on the outer sides of the grinding rollers at equal intervals along the length direction thereof;

[0007] The grinding discs provided on adjacent grinding rollers are staggered with each other;

[0008] One end of the frame is provided with a blanking assembly for scraping off the paint ground on the grinding roller.

[0009] Furthermore, the blanking assembly includes a guide plate, the shape of the guide plate is set to be an isosceles trapezoid, and the bottom edge of the guide plate is provided with scraping plates at equal intervals along its width direction, and the scraping plates are staggered with the grinding discs.

[0010] Furthermore, a reinforcing plate is fixedly connected to the bottom of the guide plate, the reinforcing plate is cross-shaped, and two opposite ends of the reinforcing plate are fixedly connected to positioning shafts, and one end of the positioning shaft is provided with a support seat for supporting the positioning shaft, and the support seat is connected to the frame.

[0011] Furthermore, one end of the positioning shaft is inserted into the opposite groove on the support seat, and the outer side of the positioning shaft is fixedly connected to a pin seat, and the pin seat is pinned to an adjustment plate;

[0012] A through slot is provided on the side of the adjustment plate;

[0013] A threaded column is fixedly connected to the side surface of the support seat, and the threaded column passes through the through slot.

[0014] Furthermore, a fixing hole is formed through one side of the bottom of the support base.

[0015] Further, the linkage mechanism includes a second pulley;

[0016] The output end of the motor is provided with a first pulley;

[0017] A belt is connected between the first pulley and the second pulley.

[0018] Furthermore, a side surface of the second pulley is connected to a first gear;

[0019] Both ends of the grinding roller are provided with a second gear;

[0020] The first gear matches the second gear at one end of the grinding roller.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] First, the motor-driven first and second pulleys are linked to synchronize the rotation of multiple grinding rollers. Staggered grinding discs are positioned on the outside of the grinding rollers. The material is subjected to multiple shear forces between the grinding discs, rotating at different speeds, ensuring thorough grinding and uniform dispersion. This design effectively addresses the uneven grinding and inefficiency issues inherent in traditional equipment, significantly improving grinding performance when processing high-viscosity, complex coatings.

[0023] By placing evenly spaced staggered grinding discs on the grinding roller, the material's path during grinding becomes more complex, increasing the number of shearing cycles. This design effectively enhances grinding efficiency, allowing the material to be fully sheared and ground in a shorter time, thereby improving the fineness and uniformity of the coating. This design solves the problem of insufficient grinding caused by the single material path in traditional equipment and is suitable for the production needs of high-quality coatings.

[0024] Furthermore, the design of the unloading assembly further ensures complete material discharge. The guide plate, in conjunction with the scraper plate, effectively scrapes away residual material from the grinding roller and grinding disc, preventing material waste. The reinforced structure of the guide plate and the support base ensure the stability and durability of the unloading assembly during operation, resolving the issues of residual material and incomplete unloading found in traditional equipment, thereby improving overall equipment operating efficiency and product quality.

Both ends of the grinding roller 4 are mounted on the frame 1 through bearings to ensure that the grinding roller 4 can rotate at high speed. Maintain stability during efficient operation; grinding discs 42 are arranged at equal intervals on the outside of the grinding roller 4 along its length direction. The grinding discs 42 are of a multi-layer structure, and the surface presents a fine convex texture, which is used to increase the shear force on the paint; the grinding discs 42 arranged on adjacent grinding rollers 4 are staggered with each other, and the materials are rotated at different speeds and directions to generate alternating shear forces, thereby achieving the effect of efficient grinding; a blanking component 5 for scraping off the paint ground on the grinding roller 4 is provided at one end of the frame 1. The blanking component 5 is in close contact with the surface of the grinding roller 4 to ensure that the ground material is thoroughly scraped off and guided to the blanking port.

[0042] See Figure 1-3 The unloading component 5 includes a guide plate 51, the shape of the guide plate 51 is set to be an isosceles trapezoid, and the guide plate 51 is provided with a plurality of guide grooves along the width direction for controlling the flow direction of the ground material to ensure that the material is evenly discharged; and the bottom edge of the guide plate 51 is provided with scrapers 511 at equal intervals along its width direction. The scraper plates 511 are made of wear-resistant material, have good flexibility and wear resistance, can fit closely to the surface of the grinding roller 4, and completely scrape off the residual material; the scraper plates 511 and the grinding disc 42 are staggered to ensure the uniformity of scraping the material during the grinding process and avoid material residue on the surface of the grinding roller 4 and the grinding disc 42.

[0043] See Figure 1 and Figure 4The bottom of the guide plate 51 is fixedly connected with a reinforcing plate 52, and the shape of the reinforcing plate 52 is cross-shaped. The structural design of the reinforcing plate 52 enhances the rigidity of the guide plate 51, avoids deformation of the guide plate 51 during scraping, and ensures the stability of the blanking assembly 5; and the opposite ends of the reinforcing plate 52 are fixedly connected with positioning shafts 53, and the positioning shafts 53 are used to support and fix the position of the guide plate 51, ensuring that the guide plate 51 does not shift in position during operation; and one end of the positioning shaft 53 is provided with a support seat 56 for supporting the positioning shaft 53, and the support seat 56 is fixedly connected to the frame 1 to provide solid support for the positioning shaft 53, thereby ensuring the stability of the blanking assembly 5 during use.

[0044] See Figure 3-4 The cam 55 is fixedly connected to the side of the adjusting plate 55 so as to prevent the cam 55 from loosening during operation.

[0045] See Figure 4 A fixing hole 561 is provided on one side of the bottom of the support seat 56. The fixing hole 561 is used to firmly fix the support seat 56 on the frame 1 through bolts, thereby ensuring the stability of the support seat 56 and the entire blanking assembly 5.

[0046] See Figure 1 The linkage mechanism 3 includes a second pulley 31, which is connected to the first pulley 21 through a belt to form a power transmission path; the output end of the motor 2 is provided with a first pulley 21, and a belt is connected between the first pulley 21 and the second pulley 31. The high-strength material of the belt ensures the effective transmission of power while avoiding the occurrence of slippage.

[0047] See Figure 1The side of the second pulley 31 is connected to a first gear 32, and the first gear 32 is engaged with the second gear 41 at one end of the grinding roller 4. The grinding roller 4 is rotated synchronously through gear transmission to ensure that the material is subjected to uniform shearing force and grinding force during the grinding process; a second gear 41 is provided at both ends of the grinding roller 4, and the second gear 41 realizes power transmission by engaging with the first gear 32, thereby driving the grinding roller 4 to rotate, so that the paint is fully ground and dispersed between the grinding roller 4 and the grinding disk 42.

[0048] The working principle of this utility model is:

[0049] When grinding the paint, the motor 2 drives the first pulley 21 to rotate. A belt is provided between the first pulley 21 and the second pulley 31, thereby driving the linkage mechanism 3 to rotate synchronously. The first gear 32 provided on the linkage mechanism 3 is engaged with the second gear 41 provided at one end of the grinding roller 4, thereby driving the grinding roller 4 to rotate.

[0050] During the rotation of the grinding roller 4, the adjacent grinding rollers 4 will grind the paint placed on the grinding roller 4. Since the outer side of the grinding roller 4 is provided with grinding discs 42 at equal intervals along its length, and the grinding discs 42 provided on adjacent grinding rollers 4 are staggered with each other, during the rotation of the grinding roller 4, the material will be guided by the multiple grinding discs 42.

[0051] When the material passes through the gap between the grinding discs 42, the different rotation speeds of adjacent grinding discs 42 will generate shear force, thereby grinding and dispersing the material; the staggered grinding discs 42 can increase the complexity of the material path and increase the number of shear times the material is subjected to.

[0052] After the material is ground, the inclination angle of the guide plate 51 is adjusted so that the scraper plate 511 fits the outer surface of the grinding roller 4 , so that the material on the surface of the grinding roller 4 and the grinding disc 42 will be scraped onto the guide plate 51 .

[0053] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
