Description

Technical Field

[0001] This utility model relates to the field of stone paint processing technology, and in particular to a granulator for producing stone paint. Background Technology

[0002] Stone paint, also known as imitation stone paint, is a thick exterior wall decorative coating that closely resembles the decorative effect of marble and granite. With careful design and construction, stone paint can present the texture, color and feel of natural stone, giving buildings a noble and elegant appearance.

[0003] For example, a granulator for producing imitation stone paint with authorization announcement number "CN221558307U" uses a spiral feeding drive mechanism to transport materials through multiple bottom holes to multiple granulation holes of the same diameter. Then, a granulation drive mechanism drives the granulation disc to rotate in the granulation chamber, thereby achieving the granulation of materials of the same particle size in multiple granulation holes. After the granulator finishes its work, residual material remains. During the flow and accumulation of material in the storage chamber, some material adheres to the inner wall of the storage chamber, making cleaning difficult. Furthermore, the granulator cannot ensure uniform mixing when pouring material into the storage chamber. Insufficient mixing of different components leads to color variations in the faux stone paint, resulting in defects such as color spots and streaks, affecting the product's aesthetics. Uneven mixing also causes localized aggregation of certain components, affecting the adhesion of the faux stone paint to the wall surface. During use, this can lead to peeling and flaking, shortening the product's lifespan and preventing the faux stone paint from forming a natural stone texture after application, reducing the product's realism and lowering the overall quality of the granulator used for faux stone paint production. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a granulator for producing stone paint, which facilitates equipment cleaning and ensures uniform material mixing.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This granulator for producing stone paint includes a granulation chamber and a first box. The upper end of the granulation chamber is fixedly connected to the first box. The right end of the first box is fixedly connected to a first shell. The interior of the first shell is provided with an impact discharge structure. The upper left side of the first box is fixedly connected to a second box. The upper end of the second box is fixedly connected to a second shell. The interior of the second shell is provided with a material mixing structure.

[0006] To further improve the design, the impact discharge structure includes a first motor, the outer wall of which is fixedly connected to a first housing. A straight rod is fixedly connected to the output shaft of the first motor. Both ends of the straight rod's rotating shaft are rotatably connected to the first housing via bearings. A pull rope is fixedly connected to the outer wall of the straight rod, and the end of the pull rope is fixedly connected to a crossbar. A spring is provided on the right side of the crossbar, and both ends of the spring are fixedly connected to the crossbar and the first housing, respectively. The upper end of the crossbar is slidably connected to a first sliding rod, and both ends of the first sliding rod are fixedly connected to the first housing. The outer wall of the crossbar is slidably connected to the first housing, and the left end of the crossbar abuts against the first box body.

[0007] To further improve the design, a sixth motor is fixedly connected to the right end of the granulation chamber, and a granulation disc is fixedly connected to the output shaft of the sixth motor. The outer wall of the granulation disc is rotatably connected to the granulation chamber through a sealed bearing, and multiple granulation holes are provided on the outer wall of the granulation disc.

[0008] Further improvements are made to the material mixing structure, which includes a second motor and a third motor. The outer wall of the second motor is fixedly connected to the second housing. The output shaft of the second motor is fixedly connected to a reciprocating lead screw. Both ends of the reciprocating lead screw are rotatably connected to the second housing via bearings. The reciprocating lead screw is threadedly connected to a lead screw nut. The left end of the lead screw nut is slidably connected to a second slide rod. The right end of the lead screw nut is fixedly connected to a first block. The inner wall of the first block is rotatably connected to a second gear via bearings. The outer wall of the third motor is fixedly connected to the second housing. The output shaft of the third motor is fixedly connected to a first gear. Both ends of the rotating shaft of the first gear are rotatably connected to the second housing via bearings. The first gear meshes with the second gear. The lower end of the rotating shaft of the second gear is fixedly connected to a stirring rod.

[0009] Further improvements include a fourth motor fixedly connected to the left end of the second housing, the output shaft of the fourth motor being rotatably connected to the second housing via a bearing, and a first helical blade fixedly connected to the output shaft of the fourth motor, the right end of which extends into the interior of the first housing.

[0010] Further improvements include a fifth motor fixedly connected to the upper end of the first housing, the output shaft of the fifth motor being rotatably connected to the first housing via a bearing, a second helical blade fixedly connected to the output shaft of the fifth motor, and multiple bottom holes fixedly connected to the lower end of the first housing, with the lower ends of the bottom holes extending into the granulation chamber.

[0011] In a further improvement, the outer wall of the stirring rod is rotatably connected to the second block via a bearing, the outer wall of the second block is slidably connected to the second housing and the second box, and the lower end of the stirring rod extends into the interior of the second box.

[0012] The beneficial effects of this utility model are as follows: Through the cooperation of the impact discharge structure and the first housing, the output shaft of the first motor rotates, driving the straight rod to rotate. The rotation of the straight rod causes the pull rope to move, which in turn causes the crossbar to slide to the right on the first sliding rod. The sliding of the first sliding rod compresses the spring. When the rotation of the straight rod causes the crossbar to move to the left, the spring rebounds, causing the crossbar to quickly impact the first housing. The left end of the crossbar is fitted with a rubber sleeve. Rubber has good elasticity and cushioning properties. When the crossbar strikes the first housing, the rubber can absorb some of the impact force, making the force transmitted to the struck object more gentle and less likely to scratch the surface of the object, unlike metal striking rods. The impact on the equipment causes residual material after operation to fall into the collection box in the above manner, making the cleaning operation of the equipment simpler.

[0013] Through the cooperation of the material mixing structure and the second shell, the output shaft of the second motor rotates, driving the reciprocating screw to rotate. The rotation of the reciprocating screw drives the screw nut to slide on the second slide rod. The movement of the screw nut drives the second block to slide up and down in the second box. The outer wall of the second block is machined with protrusions to prevent the rotation of the stirring rod from driving the second block to rotate. The output shaft of the third motor rotates, driving the first gear to rotate. The rotation of the first gear drives the stirring rod to rotate, so that the stirring rod can move up and down while rotating. This allows the stirring rod to stir the material at different height positions, realizing three-dimensional stirring operation. This allows the material to be fully stirred in the vertical direction as well, avoiding the situation of material stratification or uneven mixing at different heights. Attached Figure Description

[0032] Working principle:

[0033] Granulation process of stone paint:

[0034] The mixing stage of the stone paint:

[0035] The operator pours the granulation raw materials for stone paint production into the feed port processed at the left end of the second box 7. The material slides down into the interior of the second box 7 through the feed outlet. The external power supply of the second motor 601 and the third motor 606 is connected, and the second motor 601 and the third motor 606 are started. The output shaft of the second motor 601 rotates, driving the reciprocating screw 602 to rotate (e.g., Figure 5 The reciprocating screw 602 rotates, causing the screw nut 603 to slide on the second slide rod 604. The movement of the screw nut 603 causes the first block 605 to move. The movement of the first block 605 causes the first gear 608 to move up and down. The movement of the first gear 608 causes the stirring rod 8 to move. The movement of the stirring rod 8 causes the second block 9 to slide up and down inside the second housing 7. The outer wall of the second block 9 is machined with protrusions to prevent the stirring rod 8 from rotating and causing the second block 9 to rotate. At the same time, the output shaft of the third motor 606 rotates, causing the first gear 607 to rotate (e.g., Figure 5 The first gear 607 rotates, driving the second gear 608 to rotate within the first block 605 and the second block 9. The rotation of the second gear 608 drives the stirring rod 8 to rotate. The second motor 601 rotates, causing the stirring rod 8 to move up and down, and the third motor 606 rotates, causing the stirring rod 8 to rotate as well. This allows the stirring rod 8 to stir the material at different heights, achieving three-dimensional stirring. This ensures that the material is fully agitated vertically, preventing stratification or uneven mixing at different heights. After stirring is complete, the second motor 601 and the third motor 606 are turned off, and the contents of the second housing... A solenoid valve is installed on the lower side of the wall. When the solenoid valve is opened, the material slides down through the discharge port on the lower side of the second box 7 onto the first spiral blade 11. The external power supply of the fourth motor 10 is connected and the fourth motor 10 is started. The output shaft of the fourth motor 10 rotates, driving the first spiral blade 11 to rotate. The rotation of the first spiral blade 11 drives the material to move. When the first spiral blade 11 rotates, its surface is in direct contact with the material, and friction is generated between the two. When the first spiral blade 11 rotates, this friction will generate a pushing force on the material, causing the material to move along the spiral direction of the first spiral blade 11 until all the material is transported into the first box 2. Then the solenoid valve and the fourth motor 10 are closed.

[0036] Granulation stage of materials:

[0037] When the external power supply of the fifth motor 12 is connected and the fifth motor 12 is started, the output shaft of the fifth motor 12 rotates, driving the second spiral blade 13 to rotate (e.g. Figure 2Under the push of the second spiral blade 13 (the type of second spiral blade 13 is the same as the spiral blade in the imitation stone paint granulator with authorization announcement number "CN221558307U"), the material enters the granulation chamber 1 through the bottom hole 14 on the inner wall of the bottom side of the first housing 2. The bottom hole 14 is the same as the bottom hole in the imitation stone paint granulator with authorization announcement number "CN221558307U". The external power supply of the sixth motor 15 is connected, and the sixth motor 15 is started. The output shaft of the sixth motor 15 rotates, driving the granulation disc 16 to rotate in the granulation chamber 1. The granulation disc 16 has multiple granulation holes 17 of the same diameter. The type of granulation disc 16 is the same as the granulation disc in the imitation stone paint granulator with authorization announcement number "CN221558307U". The material entering the granulation chamber 1 rotates with the granulation disc 16. As the granulation disc 16 rotates, the material inside the granulation hole 17 is subjected to various forces, including centrifugal force, friction, and cutting force from the edge of the granulation hole. The centrifugal force causes the material to move outward from the granulation hole 17, generating friction with the sidewall of the granulation hole 17. At the same time, the edge of the granulation hole 17 cuts and shapes the material. The model of the granulation chamber 1 and the granulation hole 17 is the same as that of the granulation chamber and granulation hole in a granulator for producing imitation stone paint with authorization announcement number "CN221558307U". When the granulation disc 16 rotates to a certain angle, the particles inside the granulation hole 17 fall into the collection box at the bottom of the granulation chamber 1 through the discharge port under the action of gravity. After the material collection is completed, the fifth motor 12 and the sixth motor 15 are turned off, the collection box is removed, and a new collection box is placed below the discharge port of the granulation chamber 1. The material can be used for stone paint production later.

[0038] Equipment cleaning:

[0039] When the external power supply of the first motor 401 is connected, the output shaft of the first motor 401 rotates, driving the straight rod 402 to rotate clockwise. The rotation of the straight rod 403 causes the pull rope 403 to move (e.g., Figure 3 The pull rope 403 moves, causing the crossbar 404 to slide to the right on the first slide bar 406. The sliding of the first slide bar 406 compresses the spring 405. When the rotation of the straight rod 402 causes the crossbar 404 to move to the left, the spring 405 rebounds, causing the crossbar 404 to quickly impact the first housing 2. The left end of the crossbar 404 is fitted with a rubber sleeve. The rubber has good elasticity and cushioning performance. When the crossbar 404 strikes the first housing 2, the rubber can absorb part of the impact force, making the force transmitted to the struck object more gentle and less likely to scratch the surface of the object like a metal striking rod. The impact on the equipment causes the residual material after the equipment has been working to fall into the collection box in the above manner, making the cleaning operation of the equipment simpler. After cleaning, the collection box is removed and the first motor 401 is turned off, thus completing the processing of the granulator for producing stone paint.
