DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 The paint grinding device shown is used for the grinding production of paint, including a frame 1, a power mechanism 5 and a material collecting scraper 7. A first grinding roller 2, a second grinding roller 3 and a third grinding roller 4 are rotatably installed in the frame 1. The first grinding roller 2, the second grinding roller 3 and the third grinding roller 4 are arranged and installed in a straight line. The first grinding roller 2, the second grinding roller 3 and the third grinding roller 4 are transmission-connected with the power mechanism 5, and the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4 are driven to rotate synchronously by the power mechanism 5. A discharge box 6 is installed on the top of the frame 1. The discharge box 6 stores the paint product that needs to be ground, and the paint liquid is output from the outlet pipe of the discharge box 6. Since the outlet pipe of the discharge box 6 is directly opposite to the position between the first grinding roller 2 and the second grinding roller 3, the paint liquid is gathered at the position between the first grinding roller 2 and the second grinding roller 3 and is discharged at the first grinding roller 2. When the roller 2, the second grinding roller 3 and the third grinding roller 4 are rotating, the paint liquid can be driven to pass through the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4 in sequence, and the grinding operation is completed in the process of driving. The third grinding roller 4 is the last grinding unit, so the material scraper 7 is installed corresponding to the third grinding roller 4. The material scraper 7 can scrape and recycle the paint on the third grinding roller 4. A material collecting box 8 is placed below the outlet end of the material scraper 7. The recovered paint product finally converges into the material collecting box 8. The utility model has the advantages of reasonable structure and simple operation. The worker only needs to complete the operation of pouring the paint product into the discharge box 6 (the operation can be to pump the product or pour the product). The subsequent grinding and product recovery are all completed automatically, which is very convenient and labor-saving. After processing by the utility model, the final paint product meets the practical fineness requirements.

[0021] like Figure 2 and Figure 3As shown, there are gaps between the first grinding roller 2 and the second grinding roller 3, and between the second grinding roller 3 and the third grinding roller 4. The existence of the gaps prevents the grinding rollers from interfering with each other and causing damage to the roller surfaces when they rotate. The gap size between the rollers should be less than one millimeter. Since the coating liquid is relatively viscous and has a large liquid-liquid tension, when the gap between the rollers is less than one millimeter, the coating liquid can gather in the gap area between the rollers and will not fall. Under this feature, the coating liquid can pass through the three grinding rollers in sequence. Figure 2 As shown, after the discharge box 6 outlet pipe discharges the material, a coating liquid layer will be formed between the first grinding roller 2 and the second grinding roller 3, so that the grinding rollers can drive and grind. The discharge box 6 outlet pipe can be equipped with a flow valve to control the discharge flow so that the coating liquid layer is not too thick.

[0022] like Figure 3 As shown, the power mechanism 5 includes a motor 51, a driving gear 511 is installed on the output shaft of the motor 51, the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4 are provided with shaft heads, and the shaft heads all extend to the outside of the frame 1, the shaft head of the first grinding roller 2 is connected to the first transmission gear 52, the shaft head of the second grinding roller 3 is connected to the second transmission gear 53, and the shaft head of the third grinding roller 4 is connected to the third transmission gear 54, the driving gear 511 is meshed with the third transmission gear 54, the third transmission gear 54 is connected to the second transmission gear 53 through a chain transmission, and the second transmission gear 53 is also connected to the first transmission gear 52 through a chain transmission. Under the above structure, when the motor 51 is started, through the gear meshing relationship and the chain The transmission relationship can form the synchronous rotation of the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4. The diameter of the second transmission gear 53 is larger than that of the third transmission gear 54, and the diameter of the first transmission gear 52 is larger than that of the second transmission gear 53. When the small gear drives the large gear, the speed of the large gear becomes slower. Therefore, when the three grinding rollers are rotating, the first grinding roller 2 has the slowest speed, the second grinding roller 3 has a medium speed, and the third grinding roller 4 has the fastest speed. Only when there is a speed difference among the three grinding rollers can the driving flow effect of the coating liquid be met and friction can be generated on the coating liquid during the driving process. The coating liquid can be ground through this speed difference friction effect. Since there are three grinding rollers, it will go through two grinding passes to ensure that the fineness meets the requirements.

[0023] like Figure 4As shown, the collecting scraper 7 is an isosceles trapezoid, and the collecting scraper 7 is installed at an angle so that the collected paint liquid can flow down the scraper. The collecting scraper 7 uses the long side of the parallel sides as the high point and the short side of the parallel sides as the low point, so that a convergence effect can be formed in the flow. The high point of the collecting scraper 7 contacts the roller surface of the third grinding roller 4, and the low point of the collecting scraper 7 is located above the collecting box 8. The long side of the high point can scrape off the paint on the roller surface of the third grinding roller 4, and then the paint flows down along the collecting scraper 7 and converges, and finally flows and is collected in the collecting box 8. The two waist edges of the collecting scraper 7 are bent upward to form side barriers 71, and the side barriers 71 can prevent the paint liquid from overflowing from the edge.

[0024] like Figure 2 As shown, a drip recovery plate 11 is installed in the frame 1. The drip recovery plate 11 is arranged below the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4. It can cover the projection area of ​​the first grinding roller 2, the second grinding roller 3 and the third grinding roller 4. In actual production, paint droplets occasionally fall on the roller surface of the grinding roller. The drip recovery plate 11 plays a role in drip recovery, which can keep the equipment clean. The drip recovery plate 11 adopts a plug-in structure and can be easily removed and cleaned.

[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
