Description

Technical Field

[0001] This utility model relates to the field of paint and coating processing technology, specifically to a grinding structure for paint and coating raw materials. Background Technology

[0002] The grinding and pulverizing of solid raw materials such as pigments and fillers in paints and coatings involves refining lumpy and coarse-grained solid raw materials through grinding and pulverizing to ensure that the particle size of the raw materials is uniform and well dispersed, so that the solid raw materials can be better integrated into the paint base, thereby improving the paint's hiding power, color uniformity, and adhesion.

[0003] Referring to the Chinese utility model patent with authorization announcement number CN210965290U, a raw material crushing and grinding device for paint production is disclosed. The grinding device drives the active gear of the motor to drive the driven gear to rotate, thereby driving the first crushing roller and the second crushing roller to rotate, so as to perform primary crushing of large raw materials. Since the two crushing rollers in the device are fixed in position and cannot be adjusted, and the two are embedded in the bin, the gap between the components is compact and limited, which is not convenient for cleaning. After long-term operation, there may be a risk of dirt accumulation. Utility Model Content

[0004] The purpose of this invention is to provide a grinding structure for paint and coating raw materials, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A grinding structure for paint and coating raw materials includes a grinding box, a roller grinding mechanism, and a lifting and adjusting mechanism. The grinding box has side sliding openings on both sides, and sliding seats are installed in each side sliding opening. Guide structures are also provided on both sides of the grinding box, each guide structure connecting to a sliding seat on the same side to restrict the sliding seat to vertical movement only. The two sliding seats share a common roller grinding mechanism for crushing the raw materials. The lifting and adjusting mechanism is located on the side of the grinding box and is used to drive the roller grinding mechanism and adjust the lifting and lowering of the two sliding seats. The roller pressing and grinding mechanism includes a pair of grinding rollers, a drive motor, and a gear set. The two grinding rollers are symmetrically rotated and installed between two sliding seats. The drive motor is fixed on one of the sliding seats via a motor base, and its output shaft is fixed to the shaft end of one of the grinding rollers. The gear set is located on the side of the other sliding seat and is used to drive and connect the two grinding rollers.

[0007] Furthermore, a W-shaped grinding body is fixed inside the grinding box, and a two-stage roller pressing grinding zone is formed between the W-shaped grinding body and the walls of the two grinding rollers.

[0008] Furthermore, the W-shaped grinding body is symmetrically fixed by a pair of semi-circular arc-shaped parts, and the two arc-shaped parts are respectively positioned below the two grinding rollers, and several micro-holes are evenly distributed on the two arc-shaped parts; a two-stage roller pressing grinding zone is formed between the surface of the two arc-shaped parts and the outer wall of the two grinding rollers.

[0009] Furthermore, the fixed connection point of the two arc-shaped parts is defined as part A, and the ends of the two arc-shaped parts that are far apart from each other are defined as part B; wherein, the distance between the outer wall of the grinding roller and the surface of the arc-shaped part decreases from part A to part B.

[0010] Furthermore, guide plates are fixed at the ends of the two arc-shaped sections that are far apart from each other, and the two guide plates are arranged in an octagonal pattern; fixed feet are fixed on both sides of the guide plates, and the fixed feet are fixed to the inner wall of the grinding box.

[0011] Furthermore, the gear set includes a first gear, a second gear, and a gear cover; the gear cover is fixed to the outside of the sliding seat; the shaft ends of the corresponding sides of the two grinding rollers extend through into the gear cover, the first gear is fixed on the shaft end of one grinding roller, the second gear is fixed on the shaft end of the other grinding roller, and the first gear and the second gear mesh.

[0012] Furthermore, the lifting and adjusting mechanism includes a telescopic cylinder; the telescopic cylinder is vertically fixed to one side of the grinding box via a fixed seat, and a connecting seat is fixed on the sliding seat on the same side, with the telescopic end of the telescopic cylinder fixed to the connecting seat; wherein, the telescopic cylinder is a hydraulic cylinder.

[0013] Furthermore, the guide structure includes slide rods; side seats are fixed on the sides of the two sliding seats that are far apart from each other; guide platforms are fixed on both sides of the grinding box; the two slide rods are slidably inserted into the guide platforms in a one-to-one correspondence, and the top ends of the two slide rods are respectively fixedly connected to the side seats.

[0014] Furthermore, a feeding hopper is fixed between the two sliding seats, and the bottom of the feeding hopper slides and fits against the outer wall of the two grinding rollers.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention uses a lifting and adjusting mechanism to drive the roller grinding mechanism and sliding seat to move upward as a whole, exposing the grinding roller and making room above the W-shaped grinding body. This facilitates thorough cleaning of the grinding roller, the arc-shaped part, and the guide plate, effectively solving the problem of difficult cleaning of fixed structures.

[0017] This invention forms a two-stage roller pressing and grinding zone between the arc-shaped part and the outer wall of the grinding roller, which can refine the crushed material in a secondary manner. The edge of the micropore plays a scraping and cutting role during the grinding process, which enhances the secondary crushing effect of the crushed material. Combined with the rotation and pressure of the grinding roller, it significantly improves the grinding fineness and dispersion uniformity of the raw materials.

[0018] The distance between the outer wall of the grinding roller and the surface of the arc-shaped part decreases from part A to part B, so that the material is gradually subjected to tighter roller pressure and shearing in the secondary roller pressing grinding zone, realizing progressive crushing and improving the overall grinding efficiency. The spatial structure of the secondary roller pressing grinding zone changes dynamically with the rotation of the grinding roller. Combined with the guiding effect of the guide plate, it avoids the accumulation of fine material on the surface of the arc-shaped part and alleviates the discharge pressure.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0023] In this embodiment of the invention, 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. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Example 1

[0024] Please see Figures 1-7 This utility model provides a grinding structure for paint and coating raw materials, including a grinding box 1, a roller grinding mechanism 3, and a lifting and adjusting mechanism 4. The bottom of the grinding box 1 is a discharge port for discharging the ground fine material. Both sides of the grinding box 1 are provided with side sliding ports 11, and sliding seats 2 are installed in both side sliding ports 11. The grinding box 1 is also provided with guide structures on both sides, and the two guide structures are respectively connected to the sliding seats 2 on the same side. The guide structures limit the sliding seats 2 on the same side, so that the sliding seats 2 can only move in the vertical direction. The two sliding seats 2 are provided with a roller grinding mechanism 3 for crushing raw materials. The lifting and adjusting mechanism 4 is located on the side of the grinding box 1. Through the operation of the lifting and adjusting mechanism 4, the roller grinding mechanism 3 and the two sliding seats 2 can be driven to lift and adjust.

[0025] The roller pressing and grinding mechanism 3 includes a pair of grinding rollers 31, a drive motor 33, and a gear set. The two grinding rollers 31 are symmetrically rotated and installed between two sliding seats 2, forming a primary roller pressing and grinding zone between the two grinding rollers 31. The drive motor 33 is fixed on one of the sliding seats 2 via a motor base 32, and its output shaft is fixed to the shaft end of one of the grinding rollers 31. The gear set is located on the side of the other sliding seat 2 and is used to drive and connect the two grinding rollers 31. Specifically, the gear set includes a first gear 34, a second gear 35, and a gear cover 36. The gear cover 36 is fixed on the outside of the sliding seat 2, and the shaft ends of the corresponding sides of the two grinding rollers 31 extend through into the gear cover 36. The first gear 34 is fixed on the shaft end of one of the grinding rollers 31, and the second gear 35 is fixed on the shaft end of the other grinding roller 31, and the first gear 34 and the second gear 35 mesh.

[0026] In addition, such as Figure 4 As shown, a feeding hopper 6 is fixed between the two sliding seats 2, which is used to feed the raw materials into the primary roller grinding zone. The bottom end of the feeding hopper 6 is slidably attached to the outer wall of the two grinding rollers 31, which can prevent the material from splashing to both sides and failing to be fully ground and crushed.

[0027] The drive motor 33 operates, and its output shaft drives one side of the grinding roller 31 to rotate. Under the meshing transmission of the first gear 34 and the second gear 35, this grinding roller 31 drives the other side of the grinding roller 31 to rotate in the opposite direction. The specific rotation directions of the two grinding rollers 31 are as follows: Figure 7 As shown by the arrow, the raw material is placed into the feeding hopper 6, and the feeding hopper 6 guides the raw material to the primary roller pressing and grinding zone between the two grinding rollers 31. The raw material is crushed by the spinning and grinding action of the two grinding rollers 31.

[0028] After prolonged use, the components inside the grinding box 1 need to be cleaned. By operating the lifting and adjusting mechanism 4, the sliding seat 2 and the roller grinding mechanism 3 are driven to move upward as a whole. Both sliding seats 2 are dislodged upward from the side sliding opening 11. At this time, the two grinding rollers 31 are partially exposed. The grinding rollers 31 can be cleaned by rotating them while cleaning. Since the sliding seat 2 and the roller grinding mechanism 3 move upward as a whole, the internal space of the grinding box 1 is freed up, which also makes it convenient to clean the corresponding positions inside the grinding box 1. After cleaning, the lifting and adjusting mechanism 4 drives the sliding seat 2 and the roller grinding mechanism 3 to move downward as a whole until the sliding seat 2 is fully matched and reset in the side sliding opening 11. Example 2

[0029] Please see Figure 2 and Figure 3 Based on Example 1, this example is used to explain in detail the guide structure and the lifting adjustment mechanism 4, as follows: The guiding structure includes slide rods 5, and side seats 51 are fixed on the side of the two sliding seats 2 that are far apart from each other. Guide tables 52 are fixed on both sides of the grinding box 1. The two slide rods 5 are slidably inserted into the guide tables 52 in a one-to-one correspondence, and the top ends of the two slide rods 5 are respectively fixedly connected to the side seats 51. By utilizing the sliding cooperation between the slide rods 5 on both sides and the guide tables 52, the sliding seats 2 and the roller grinding mechanism 3 can play a guiding, limiting and supporting role, ensuring that the lifting and adjusting process is smooth and stable enough.

[0030] The lifting and adjusting mechanism 4 includes a telescopic cylinder 42, which is vertically fixed to one side of the grinding box 1 via a fixed seat 41. A connecting seat 43 is fixed on the sliding seat 2 on the same side. The telescopic end of the telescopic cylinder 42 is fixed to the connecting seat 43. The telescopic cylinder 42 is a hydraulic cylinder. Through the telescopic operation of the telescopic cylinder 42, its telescopic end, under the fixed connection of the connecting seat 43, can drive the sliding seat 2 on the same side to lift and adjust, thereby driving the overall structure composed of the two sliding seats 2 and the roller grinding mechanism 3 to perform positive adjustment.

[0031] In addition, the telescopic cylinder 42 can also be selected from linear drive structures such as pneumatic cylinders, electric cylinders, and lead screws. Example 3

[0032] Please see Figures 4-7 The difference between this embodiment and Embodiment 2 is that: A W-shaped grinding body 7 is fixed inside the grinding box 1. The W-shaped grinding body 7 is formed by a pair of semi-circular arc-shaped parts 71 symmetrically fixed. The two arc-shaped parts 71 are respectively positioned below the two grinding rollers 31. A number of micro-holes 711 are evenly distributed on the two arc-shaped parts 71. A secondary roller pressing grinding zone is formed between the surface of the two arc-shaped parts 71 and the outer wall of the two grinding rollers 31. After the raw material is initially pressed and ground by the two grinding rollers 31, it can be diverted to the upper part of the two arc-shaped parts 71. Fine material with the required particle size can leak down from the micro-holes 711 and be discharged from the discharge port at the bottom of the grinding box 1. The broken material with the incorrect particle size remains in the secondary roller pressing grinding zone. As the grinding rollers 31 rotate, the arc-shaped parts 71 can continue to grind and refine the broken material until it leaks down from the micro-holes 711.

[0033] When the crushed material is ground and crushed in the secondary roller pressing and grinding zone, the edges of the micro-hole 711 port can act as a crushing blade, which can scrape and cut the crushed material, intensify the crushing of the material, and improve the secondary roller pressing and grinding effect in conjunction with the spinning action of the grinding roller 31.

[0034] In addition, during the grinding process, the two grinding rollers 31 move continuously relative to the arc-shaped part 71, which causes the spatial structure of the secondary roller pressing grinding zone to change dynamically. Combined with the subsequent pushing of the broken material, the accumulation of broken material in the secondary roller pressing grinding zone can be avoided, further improving the secondary grinding effect of the broken material.

[0035] Two guide plates 72 are fixed at opposite ends of the two arc-shaped parts 71. The two guide plates 72 are arranged in an octagonal shape. Fixing feet 73 are fixed on both sides of the guide plates 72. The fixing feet 73 are fixed to the inner wall of the grinding box 1. The fixing feet 73 can be fixed by welding or bolts, thereby realizing the overall fixed installation of the W-shaped grinding body 7.

[0036] like Figure 7 As shown, the fixed connection point of the two arc-shaped parts 71 is defined as part A 01, and the ends of the two arc-shaped parts 71 that are far apart from each other are defined as part B 02. The distance between the outer wall of the grinding roller 31 and the surface of the arc-shaped part 71 decreases from part A 01 to part B 02, so that the scrap can gradually receive tighter rolling and cutting in the secondary roller pressing and grinding zone, ensuring the sufficiency of secondary grinding.

[0037] Furthermore, the gap between the B section 02 of the two arc-shaped sections 71 and the outer wall of the corresponding grinding roller 31 allows fine materials with the required particle size to pass through. Combined with the swirling force of the grinding roller 31, the fine materials with the required particle size can be discharged from the gap to the guide plate 72. The guide plate 72 then guides these fine materials downwards, and finally discharges them from the discharge port at the bottom of the grinding box 1. This further prevents the fine materials from accumulating continuously in the secondary roller grinding zone and alleviates the pressure of the fine materials being discharged downwards.

[0038] In addition, when the lifting adjustment mechanism 4 drives the sliding seat 2 and the roller grinding mechanism 3 to move upward as a whole, while the grinding roller 31 is exposed, the space above the two arc-shaped parts 71 and the guide plate 72 can be made open, which makes it easier to clean the W-shaped grinding body 7.

[0039] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
