Description

Technical Field

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

[0002] Paint, as a chemical mixture coating applied to the surface of an object to achieve protection, generally consists of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. Paint coatings are made by mixing and proportioning the ingredients, which are mostly in powder form.

[0003] The preparation of powdered ingredients requires the use of grinding equipment, because the quality of the powdered ingredients plays a crucial role in the effect of paint and coating. For this reason, the grinding equipment used to produce powdered ingredients is particularly important. However, existing grinding equipment still has shortcomings in solving the problem of whether the powdered ingredients are ground sufficiently. It is easy to produce powdered ingredients with excessively large particle diameters, and there is also the phenomenon of powder being blown out of the equipment during grinding. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes a paint coating material mixing, processing, and grinding equipment, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A paint coating material mixing and grinding device includes a base, a control box on one side of the bottom of the base, a feed inlet at the top of the base, a transmission channel in the space below the feed inlet, a first crushing mechanism in the transmission channel, a second crushing mechanism connected to the transmission channel in the space behind the first crushing mechanism in the base, a bottom-inclined shell in the base outside the second crushing mechanism, a grinding roller connected to the shell outside the second crushing mechanism, a discharge port on the wall near the lowest end of the shell in the base, and a power source electrically connected to the control box in the end of the base away from the second crushing mechanism. The power source is connected to both the first and second crushing mechanisms to transmit kinetic energy.

[0006] As a further embodiment of this utility model, the first crushing mechanism includes a first connecting shaft, a first fixed seat, and a first cutting blade.

The first connecting shaft is movably connected to the middle of the first fixed seat and extends into the transmission channel. The side wall of the first connecting shaft is provided with a plurality of first cutting blades distributed from top to bottom. The output end of the power source is connected to a first bevel gear. A first transmission shaft is provided in the base above the first bevel gear. Second bevel gears are provided at the upper and lower ends of the first transmission shaft. A second transmission shaft is connected through one side of the first fixed seat. A third bevel gear that mates with the second bevel gear is provided at one end of the second transmission shaft that extends outside the first fixed seat. A fourth bevel gear is provided at one end of the second transmission shaft that is located inside the first fixed seat. A fifth bevel gear that mates with the fourth bevel gear is provided at the top of the first connecting shaft.

[0007] As a further embodiment of this utility model, the second crushing mechanism includes a roller, a second connecting shaft, and a second cutting blade. The base is located in the space behind the first crushing mechanism and has at least two second fixed seats. The two ends of the roller are rotatably fitted into the second fixed seats. The end of the transmission channel is connected to the end of the roller with an opening. The side wall of the roller has several through holes circumferentially. The base is located in the space near the non-open end of the roller and has a fixed block. The second connecting shaft is fixedly connected to the end of the fixed block and extends into the roller. The side wall of the second connecting shaft has several second cutting blades arranged in a straight line. The cutting edge of the second cutting blade is located inside the through hole. The output end of the power source is provided with a third transmission shaft extending into the base space below the roller. The third transmission shaft has a first transmission wheel located outside the grinding roller. The first transmission wheel is in contact with both ends of the roller to achieve transmission.

[0008] As a further embodiment of this utility model, the two ends of the grinding roller pass through the walls on both sides of the housing and are connected to a second transmission wheel located outside the housing. The housing outside the second transmission wheel is provided with a third fixed seat. The third fixed seat is connected to the third transmission wheel through a rotating shaft. The third transmission wheel is in contact with the first transmission wheel and the second transmission wheel to realize the transmission to the grinding roller.

[0009] As a further embodiment of the present invention, the end of the transmission channel near the feed inlet and the end of the transmission channel near the roller are both provided with arc-shaped guide surfaces.

[0010] As a further embodiment of this utility model, both the feed inlet and the discharge outlet are provided with mating openings that protrude towards the machine base.

[0011] As a further embodiment of this utility model, the feed inlet is connected to a cover plate via a hinge.

[0012] The beneficial effects of this utility model are as follows: the grinding equipment can crush large particles in the raw material powder through the first crushing mechanism, and then grind them by the second crushing mechanism and grinding roller, so that the large particles in the raw material powder are further crushed, the particle size of the raw material powder is more uniform, and the problem of paint and coating raw material powder spreading around the grinding equipment during the processing can also be avoided.

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0022] This utility model discloses a batching, processing, and grinding equipment for paints and coatings, such as... Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the machine includes a base 1, a control box 2 on one side of the bottom end of the base 1, a feed inlet 11 at the top end of the base 1, a transmission channel 3 in the space below the feed inlet 11, a first crushing mechanism 4 in the transmission channel 3, a second crushing mechanism 5 connected to the transmission channel 3 in the space behind the first crushing mechanism 4 in the base 1, a bottom-inclined housing 6 in the base 1 outside the second crushing mechanism 5, a grinding roller 7 connected to the housing 6 outside the second crushing mechanism 5, a discharge port 12 on the wall near the lowest end of the housing 6 in the base 1, and a power source 8 electrically connected to the control box 2 in the end of the base 1 away from the second crushing mechanism 5. The power source 8 is connected to the first crushing mechanism 4 and the second crushing mechanism 5 respectively to realize the transmission of kinetic energy.

[0023] It should be noted that: the paint powder can be fed into the transmission channel 3 through the inlet 11 via a conveyor belt. A sealing block (not shown in the figure) is inserted into the outlet 12 to ensure the outlet 12 is sealed. Then, the operator starts the power source 8 through the control box 2, so that the power source 8 outputs power to the first crushing mechanism 4 and the second crushing mechanism 5. After the paint powder enters the transmission channel 3, the first crushing mechanism 4 crushes the powder entering the transmission channel 3, dispersing the large particles in the powder. After being processed by the first crushing mechanism 4, the powder is transported by the transmission channel 3 to... The second crushing mechanism 5 grinds the powder ingredients, dispersing large particles into smaller ones. After processing by the second crushing mechanism 5, the powder falls into the housing 6. The grinding roller 7, rotating within the housing 6, presses the powder against the second crushing mechanism 5 and the surface of the housing 6, thus grinding the powder within the housing 6. Both the grinding roller 7 and the second crushing mechanism 5 grind the powder within the housing 6, resulting in powder with uniform particle size. This grinding equipment can not only perform graded grinding of paint and coating powder ingredients, but also allow the entire grinding process to be carried out in a completely enclosed state, thus preventing the paint and coating powder ingredients from spreading around the grinding equipment during processing.

[0024] It needs to be further explained that, such as Figure 2 and Figure 3As shown, the first crushing mechanism 4 includes a first connecting shaft 41, a first fixed seat 42, and a first cutting blade 43. The first fixed seat 42 is fixedly connected to the inner wall of the base 1 near the feed inlet 11. The first connecting shaft 41 is movably connected to the middle of the first fixed seat 42 and extends into the transmission channel 3. The side wall of the first connecting shaft 41 is circumferentially provided with a plurality of first cutting blades 43 distributed from top to bottom. The output end of the power source 8 is connected to a first bevel gear 44. A first transmission shaft 45 is provided in the base 1 above the first bevel gear 44. The upper and lower ends of the first transmission shaft 45 are provided with second bevel gears 46. A second transmission shaft 47 is connected through one side of the first fixed seat 42. The end of the second transmission shaft 47 that extends outside the first fixed seat 42 is provided with a third bevel gear 48 that cooperates with the second bevel gear. The end of the second transmission shaft 47 located inside the first fixed seat 42 is provided with a fourth bevel gear 49. The top end of the first connecting shaft 41 is provided with a fifth bevel gear 410 that cooperates with the fourth bevel gear 49.

[0025] In this process, the power source 8 drives the first connecting shaft 41 to rotate. The first cutting blade 43 rotates in the transmission channel 3 under the drive of the first connecting shaft 41. The powder entering the transmission channel 3 collides with the first cutting blade 43. After colliding with the surface of the first cutting blade 43, the powder not only breaks up the loose large particles, but also cuts them into smaller particles after colliding with the blade of the first cutting blade 43. Then the powder falls to the bottom of the transmission channel 3 and enters the next processing step.

[0026] It needs to be further explained that, such as Figure 2 , Figure 4 and Figure 5 As shown, the second crushing mechanism 5 includes a roller 51, a second connecting shaft 52, and a second cutting blade 53. The base 1 is located in the space behind the first crushing mechanism 4 and has at least two second fixed seats 54. The two ends of the roller 51 are rotatably fitted into the second fixed seats 54. The end of the transmission channel 3 is connected to the end of the roller 51 with an opening. The side wall of the roller 51 has several through holes 511 circumferentially. The base 1 has a fixed block 55 in the space near the non-open end of the roller 51. The second connecting shaft 52 is fixedly connected to the end of the fixed block 55 and extends into the roller 51. The side wall of the second connecting shaft 52 has several second cutting blades 53 arranged in a straight line. The blades of the second cutting blades 53 are located inside the through holes 511. The output end of the power source 8 has a third transmission shaft 56 extending into the space of the base 1 below the roller 51. The third transmission shaft 56 has a first transmission wheel 57 located outside the grinding roller 7. The first transmission wheel 57 is attached to both ends of the roller 51 to realize transmission.

[0027] In this process, the power source 8 drives the second connecting shaft 52 to rotate, which in turn drives the first transmission wheel 57 to rotate. The first transmission wheel 57 then drives the drum 51 to rotate. The powder material falling to the bottom of the transmission channel 3 enters the drum 51 from the opening side. The powder material with small particle diameter falls into the housing 6 through the through hole 511 during the rotation of the drum 51. The large particles that cannot pass through the through hole 511 will roll with the drum 51 inside the drum. The powder material with large particle diameter will be broken up after colliding with the inside of the drum 51. Moreover, the powder material with large particle diameter will collide with the second cutting blade 53 when it rolls inside the drum 51. After the powder material collides with the surface of the second cutting blade 53, it can not only break up the loose large particles, but also cut them into smaller particles after colliding with the blade of the second cutting blade 53, thereby achieving the grinding effect of the powder material.

[0028] Specifically, such as Figure 2 and Figure 6 As shown, the two ends of the grinding roller 7 pass through the walls on both sides of the housing 6 and are connected to a second transmission wheel 71 located outside the housing 6. The housing 6 outside the second transmission wheel 71 is provided with a third fixed seat 61. The third fixed seat 61 is connected to a third transmission wheel 62 through a rotating shaft. The third transmission wheel 62 is in contact with the first transmission wheel 57 and the second transmission wheel 71 to realize the transmission to the grinding roller 7.

[0029] When the first drive wheel 57 rotates, it drives the third drive wheel 62 to rotate. After the third drive wheel 62 rotates, it drives the second drive wheel 71 to rotate, thereby driving the grinding roller 7 to rotate. This allows the roller 51 and the grinding roller 7 to rotate simultaneously to grind the powder.

[0030] It needs to be further explained that, such as Figure 2 As shown, the end of the transmission channel 3 near the feed inlet 11 and the end of the transmission channel 3 near the roller 51 are both provided with arc-shaped guide surfaces 31.

[0031] The guide surface 31 allows the powder entering from the feed inlet 11 to more easily enter the transmission channel 3. The guide surface 31 at the end of the transmission channel 3 allows the powder processed by the first crushing mechanism 4 to more easily reach the opening of the drum 51 and enter the drum 51. Both guide surfaces 31 guide the powder.

[0032] It needs to be further explained that, such as Figure 1 As shown, both the feed inlet 11 and the discharge outlet 12 are provided with mating openings 9 that protrude toward the machine base 1.

[0033] When the paint powder is conveyed to the feed inlet 11 by the conveyor belt, the fitting port 9 allows a soft conduit to be fitted onto the feed inlet 11, making it easier for the powder on the conveyor belt to be transferred to the feed inlet 11 and enter the equipment; similarly, the fitting port 9 on the discharge port 12 allows a soft conduit to be fitted onto the discharge port 12, making it convenient to collect the powder.

[0034] It needs to be further explained that, such as Figure 1 As shown, the feed inlet 11 is connected to a cover plate 111 via a hinge.

[0035] After all the powder ingredients have been fed, the cover plate 111 can be placed on the feed port 11 to close the feed port 11 and seal the machine base 1 port. This ensures that the grinding equipment is kept completely closed and prevents the powder ingredients of paint and coatings from spreading around the grinding equipment during the processing.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
