Description

Technical Field

[0001] The present invention relates to the technical field of raw material crushing, and particularly to a raw material crushing device and method for producing an environmentally friendly antibacterial ecological exterior wall coating. Background Art

[0002] The production raw materials of the environmentally friendly antibacterial ecological exterior wall coating mainly include a variety of inorganic and organic components, aiming to provide excellent environmental protection performance, antibacterial performance, as well as the durability and weather resistance required for the exterior wall. In terms of inorganic raw materials, commonly used ones include shell powder, aluminum hydroxide, calcium oxide, magnesium silicate, zeolite powder, etc. These raw materials not only have the characteristics of environmental protection and non-toxicity, but also can provide excellent physical and chemical properties for the coating, such as hardness, wear resistance, and weather resistance. The organic raw materials mainly include pure acrylic emulsion, styrene-acrylic emulsion, surfactant, polyethylene glycol, polyvinyl alcohol, etc. These components can enhance the film-forming property, adhesion, and fluidity of the coating, making the coating easier to construct and form a uniform coating. In addition, in order to endow the coating with antibacterial performance, a certain amount of antibacterial agents, such as nano silver, silver ions, etc., will be added. These antibacterial agents can effectively kill or inhibit the growth of microorganisms such as bacteria and molds, thereby maintaining the cleanliness and hygiene of the exterior wall. However, in the production process of the environmentally friendly antibacterial ecological exterior wall coating, a crushing device is required to crush the raw materials, and the existing crushing devices still have the following defects:

[0003] The crushed materials may have uneven particle sizes, which will directly affect the quality of the final product and the overall performance. Moreover, the materials with uneven particle sizes may require more energy and time for further processing in the subsequent processing to meet the required particle size requirements. This not only increases the production cost but also reduces the production efficiency. Also, in the mixing process, the materials with uneven particle sizes will cause the mixing speed to slow down and the mixing uniformity to decrease. This may affect the overall performance and consistency of the product. In addition, in the classification process, the materials with uneven particle sizes will lead to poor classification effects. The classifier may not be able to accurately separate the materials with different particle sizes, thus affecting the subsequent processing. In addition, the materials with uneven particle sizes may have poor fluidity during transportation and storage. This may cause the materials to block in the pipeline or storage tank, affecting the smooth progress of the production process. And, it affects the production continuity. The uneven fineness of the raw material crushing leads to frequent shutdowns to adjust the equipment, seriously disrupting the original production plan and significantly reducing the overall production efficiency and production capacity stability. Summary of the Invention

[0046] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings of the specification.

[0047] Example 1, refer to Figures 1 - 9, which is the first embodiment of the present invention, provides a raw material crushing device for the production of an environmentally friendly antibacterial ecological exterior wall coating, including a crushing box 1, a feed bin 11 fixedly connected to the top of the crushing box 1, and a discharge port 12 fixedly connected to the bottom of the crushing box 1. It also includes a crushing unit installed on the crushing box 1 and the feed bin 11; the crushing unit includes a pretreatment component installed on the crushing box 1 and the feed bin 11, and a feeding component installed on the crushing box 1. The pretreatment component includes a first crushing assembly 2 installed on the crushing box 1, and a pressing-down component 3 installed on the crushing box 1 and the feed bin 11; the first crushing assembly 2 includes two mutually meshing first crushing rollers 21 rotatably connected inside the crushing box 1, first straight gears 23 respectively sleeved on the rotating shafts of the two first crushing rollers 21, the two first straight gears 23 are mutually meshing, a first driving motor 22 fixedly connected to the top rear side of the crushing box 1, and the output shaft of the first driving motor 22 is fixedly connected to the rotating shaft of one of the first crushing rollers 21.

[0048] Specifically, during use, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are put into the feed bin 11. Through the feed bin 11, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating enter the crushing box 1. Through the crushing unit, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are crushed. After that, through the discharge port 12, the crushed raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are discharged. Through the pretreatment component, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating can be pretreated, making it easier to crush the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating during crushing. Through the feeding component, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating can be evenly scattered on the crushing unit, making the crushing of the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating more uniform, so that the particle size of the crushed material is uniform. Through the first crushing assembly 2, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are subjected to preliminary crushing treatment. Through the pressing-down component 3, when the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are crushed, they are pressed down, making it easier to crush the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating. Through the first driving motor 22, one of the first crushing rollers 21 is driven to rotate, driving one of the first straight gears 23 to rotate, and then driving the other first straight gear 23 to rotate. And the two first straight gears 23 rotate in opposite directions, driving the other first crushing roller 21 to rotate in the reverse direction. Under the rotation of the two first crushing rollers 21, the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating are subjected to preliminary crushing treatment, thereby reducing the difficulty of crushing the raw materials for the production of the environmentally friendly antibacterial ecological exterior wall coating during the crushing process.

[0049] Refer to Figure 7 and Figure 8, the pressing-down assembly 3 includes two top plates 31 that are symmetrically distributed and rotatably connected inside the feed bin 11, two first connecting shafts 32 that are symmetrically distributed and rotatably connected to the feed bin 11, the first connecting shaft 32 is fixedly connected to the corresponding top plate 31, two lower pressing plates 310 that are symmetrically distributed and rotatably connected inside the crushing box 1, two second connecting shafts 39 that are symmetrically distributed and rotatably connected to the crushing box 1, the second connecting shaft 39 is fixedly connected to the corresponding lower pressing plate 310, third spur gears 38 fixedly sleeved on the first connecting shaft 32 and the second connecting shaft 39 respectively, two chutes that are symmetrically distributed and opened on the feed bin 11 and the crushing box 1 respectively, a limiting frame 311 slidably connected to the inner side of the chute, a first spring 36 fixedly connected between the limiting frame 311 and the inner wall of the chute, a second rack 37 fixedly connected to the limiting frame 311, a first rack 35 fixedly connected to the second rack 37, the third spur gear 38 is meshed and connected with the second rack 37, a fixing plate 33 fixedly connected to the feed bin 11, a second spur gear 34 rotatably connected to the fixing plate 33, and the second spur gear 34 is meshed and connected with the first rack 35.

[0050] Specifically, when the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating enter the feed bin 11, under the action of gravity, the two top plates 31 are pressed down, causing the two top plates 31 to rotate downward, opening the channel of the feed bin 11. When the two top plates 31 rotate, they drive the first connecting shaft 32 to rotate, drive the third spur gear 38 connected thereto to rotate, drive the second rack 37 meshed and connected thereto to slide, drive the limiting frame 311 connected thereto to move, squeeze the first spring 36 connected thereto, drive the first rack 35 to move, cause the second spur gear 34 to rotate on the fixing plate 33, drive the first rack 35 at the bottom to move upward, drive the second rack 37 connected thereto to move, drive the third spur gear 38 meshed and connected thereto to rotate, drive the second connecting shaft 39 to rotate, drive the limiting frame 311 at the bottom to slide, squeeze the first spring 36, causing the lower pressing plate 310 to rotate upward. When the two top plates 31 rotate downward and open, the two lower pressing plates 310 just rotate upward and open, enabling the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating to pass through the feed bin 11 and enter the crushing box 1. When the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating enter the crushing box 1, the first spring 36 resets, driving the limiting frames 311 on the upper and lower sides to move and reset, driving the first rack 35 and the second rack 37 to move and reset, driving the third spur gear 38 to rotate and reset, driving the first connecting shaft 32 and the second connecting shaft 39 to rotate and reset, and then driving the top plate 31 and the lower pressing plate 310 to rotate and reset. When the two lower pressing plates 310 close, they press down the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating on the first crushing roller 21, making it easier to crush the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating.

[0051] Refer to Figures 9 - 16, the feeding component includes a feeding assembly 4 installed in the crushing box 1, a pushing assembly 5 installed on the feeding assembly 4, a scraping assembly 6 installed in the feeding assembly 4, a pushing assembly 7 installed on one side of the scraping assembly 6, and a reset assembly 8 installed in the feeding assembly 4; the feeding assembly 4 includes a feeding funnel 47 fixedly connected in the crushing box 1, two arc-shaped blocks 41 symmetrically distributed and fixedly connected to the bottom of the feeding funnel 47, a feeding roller 42 rotatably connected between the two arc-shaped blocks 41, a plurality of feeding grooves 46 annularly and arrayedly distributed on the feeding roller 42, a feeding shaft 43 rotatably connected to the crushing box 1, a feeding disk 44 fixedly sleeved on the feeding shaft 43, and a plurality of protrusions 45 annularly and arrayedly distributed and fixedly connected to the feeding disk 44.

[0052] Specifically, the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings that have been pretreated and crushed will fall into the feeding funnel 47, and then part of the raw materials will fall into the feeding grooves 46. By rotating the feeding disk 44, the feeding shaft 43 is driven to rotate, the feeding roller 42 is driven to rotate, and the feeding grooves 46 are driven to rotate. As a result, the feeding grooves 46 filled with raw materials rotate downward, and the empty feeding grooves 46 rotate upward. When the feeding groove 46 rotates to the opening facing downward, the raw materials in the feeding groove 46 will fall under the action of gravity. At the same time, under the action of the two arc-shaped blocks 41, the raw materials in the feeding grooves 46 on both sides of the feeding roller 42 will not fall off. When the feeding roller 42 rotates, as long as the opening of the feeding groove 46 faces downward, the raw materials in the feeding groove 46 will fall, enabling the raw materials to be evenly scattered on the crushing unit.

[0053] Refer to Figure 10 , the pushing assembly 5 includes a pushing shaft 53 rotatably connected to the crushing box 1, a pushing disk 51 fixedly sleeved on the pushing shaft 53, a notch 52 opened on the pushing disk 51, the notch 52 is engaged and connected with a plurality of protrusions 45 respectively, and a first belt 54 sleeved between the pushing shaft 53 and the rotating shaft of the first crushing roller 21.

[0054] Specifically, when the first crushing roller 21 rotates, it drives its rotating shaft to rotate. Under the action of the first belt 54, the pushing shaft 53 is driven to rotate, the pushing disk 51 is driven to rotate, and the notch 52 is driven to rotate. When the notch 52 is engaged with one of the protrusions 45, the feeding disk 44 is driven to rotate. When the notch 52 rotates past and is no longer engaged with the protrusion 45, the feeding disk 44 stops rotating. As a result, the feeding disk 44 can rotate intermittently, driving the feeding roller 42 to rotate intermittently, so that the raw materials in the feeding grooves 46 can completely fall off.

[0055] Example 2, refer to Figure 12 and Figure 13, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the scraping component 6 includes a scraping plate 61 slidably connected in the feeding groove 46, a slotted opening provided at one end of the feeding roller 42, a connecting rod 62 slidably connected in the slotted opening, one end of the connecting rod 62 extending into the feeding groove 46 and fixedly connected to the scraping plate 61, and a wedge block 63 fixedly connected to the other end of the connecting rod 62.

[0056] Specifically, when the wedge block 63 moves, it drives the connecting rod 62 to move, drives the scraping plate 61 to slide in the feeding groove 46, and pushes the raw materials in the feeding groove 46 downward, so that all the raw materials in the feeding groove 46 can fall from the feeding groove 46, avoiding the raw materials sticking in the feeding groove 46 and affecting the feeding.

[0057] Referring to Figures 13 - 15 , the pushing component 7 includes a rotating rod 71 rotatably connected to the crushing box 1, a fourth straight gear 72 fixedly sleeved on the rotating rod 71, a pushing shaft 74 rotatably connected to the crushing box 1, an incomplete gear 73 fixedly sleeved on the pushing shaft 74, the incomplete gear 73 meshing with the fourth straight gear 72, a spiral groove 75 provided on the rotating rod 71, a straight groove 76 provided on the rotating rod 71 and communicating with the spiral groove 75, a cavity provided on the crushing box 1, a moving rod 77 slidably connected in the cavity, a pushing spring 79 fixedly connected between the moving rod 77 and the inner wall of the cavity, a moving block 710 fixedly connected to the top of the moving rod 77, the moving block 710 being slidably connected to the inner sides of the spiral groove 75 and the straight groove 76 respectively, and a pushing block 78 fixedly connected to one end of the moving rod 77, the pushing block 78 being slidably connected to the inclined surface of the wedge block 63.

[0058] Specifically, the pushing shaft 74 rotates, driving the incomplete gear 73 to rotate, driving the fourth spur gear 72 to rotate, driving the rotating rod 71 to rotate. The diameter of the incomplete gear 73 is larger than that of the fourth spur gear 72, but the number of teeth of the incomplete gear 73 is the same as that of the fourth spur gear 72. When the incomplete gear 73 rotates one circle, it can drive the fourth spur gear 72 to rotate one circle. And when the incomplete gear 73 is not engaged with the fourth spur gear 72, the fourth spur gear 72 stops rotating. Under the action of the spiral groove 75, the moving block 710 is driven to rotate. Under the action of the moving rod 77, the moving block 710 moves towards the wedge block 63, driving the moving rod 77 to move towards the wedge block 63, stretching the pushing spring 79, so that the pushing block 78 moves towards the wedge block 63, and the pushing block 78 slides on the inclined surface of the wedge block 63, pushing the wedge block 63 to move downward. When the fourth spur gear 72 stops, the moving block 710 slides out of the spiral groove 75 into the straight groove 76. At this time, the pushing spring 79 resets, driving the moving rod 77 to move away from the wedge block 63, so that the moving block 710 moves away from the wedge block 63 in the straight groove 76. Since there is a certain distance between the pushing block 78 and the wedge block 63, when the rotating rod 71 rotates, it drives the pushing block 78 to move, but it has not yet slid on the inclined surface of the wedge block 63. That is, when the notch 52 is separated from the protrusion 45, the feeding tray 44 stops, and one of the feeding grooves 46 just opens vertically downward, so that the wedge block 63 stops, and the pushing block 78 slides on the inclined surface after walking this distance, thereby pushing the wedge block 63 to move. The rest of the structure is the same as that of Embodiment 1.

[0059] Embodiment 3, referring to Figure 16 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the reset assembly 8 includes a movable cavity 81 opened at the other end of the feeding roller 42, a reset rod 82 slidably connected in the movable cavity 81, and a reset spring 83 fixedly connected between the reset rod 82 and the inner wall of the movable cavity 81. The reset spring 83 is sleeved on the reset rod 82, and one end of the reset rod 82 extends into the feeding groove 46 and is fixedly connected to the scraping plate 61.

[0060] Specifically, when the scraping plate 61 moves towards the opening end inside the feeding groove 46, it drives the reset rod 82 to move, squeezing the reset spring 83. When the pushing block 78 no longer presses the wedge block 63, the reset spring 83 will reset, causing the reset rod 82 to move into the movable cavity 81, driving the scraping plate 61 to move away from the opening of the feeding groove 46, so as to prevent the scraping plate 61 from staying at the opening of the feeding groove 46 and affecting the raw materials in the feeding funnel 47 from entering the feeding groove 46.

[0061] Referring to Figure 17, the crushing unit further includes a second crushing assembly 9 disposed in the crushing box 1. The second crushing assembly 9 includes two second crushing rollers 91 rotatably connected in the crushing box 1 and meshed with each other, fifth spur gears 92 fixedly sleeved on the rotating shafts of the two second crushing rollers 91 respectively, the two fifth spur gears 92 are meshed with each other, a second driving motor 93 fixedly connected to the rear side wall of the crushing box 1, the output shaft of the second driving motor 93 is fixedly connected to the rotating shaft of one of the second crushing rollers 91, and a second belt 94 sleeved between the pushing shaft 74 and the rotating shaft of the second crushing roller 91.

[0062] Specifically, through the second driving motor 93, one of the second crushing rollers 91 is driven to rotate, one of the fifth spur gears 92 is driven to rotate, the other fifth spur gear 92 is driven to rotate in the reverse direction, and the other second crushing roller 91 is driven to rotate, so that the two second crushing rollers 91 rotate in the reverse direction to crush the raw materials falling from the feeding trough 46 again. When the second crushing roller 91 rotates, the pushing shaft 74 is driven to rotate through the second belt 94. The rest of the structure is the same as that of Embodiment 2.

[0063] Embodiment 4, referring to Figures 1 - 17 , is the fourth embodiment of the present invention, and provides: a method for using a raw material crushing device for producing an environmentally friendly antibacterial ecological exterior wall coating, including the following steps:

[0064] S1: Pour the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating into the feeding bin 11. Under the action of gravity, the raw materials will press down the two top plates 31, and through the pressing assembly 3, the two lower pressing plates 310 press the raw materials, making the raw materials easier to be crushed.

[0065] S2: The preliminarily crushed raw materials will fall into the feeding funnel 47 and then into the feeding trough 46. The feeding disk 44 is driven to rotate through the pushing assembly 5, so that the raw materials in the feeding trough 46 are evenly placed on the second crushing roller 91.

[0066] S3: Through the rotation of the pushing shaft 74, the incomplete gear 73 is driven to rotate, the fourth spur gear 72 is driven to rotate, the rotating rod 71 is driven to rotate, the pushing block 78 is driven to move, slide on the inclined surface of the wedge block 63, drive the wedge block 63 to move, so that the scraping plate 61 moves in the feeding trough 46 to scrape the raw materials in the feeding trough 46; the diameter of the incomplete gear 73 is larger than that of the fourth spur gear 72, but the number of teeth of the incomplete gear 73 is the same as that of the fourth spur gear 72. When the incomplete gear 73 rotates one circle, the fourth spur gear 72 can be driven to rotate one circle.

[0067] S4: When the scraping plate 61 moves, it drives the reset rod 82 to move, compressing the reset spring 83. When the scraping plate 61 stops moving, under the action of the reset of the reset spring 83, it drives the reset rod 82 to move back into the movable cavity 81.

[0068] Combining Embodiments 1-4, the working principle of the present invention is as follows: When in use, pour the raw materials for producing the environmentally friendly antibacterial ecological exterior wall coating into the feed bin 11. Under the action of gravity, the raw materials will press down on the two top plates 31, causing the two top plates 31 to rotate downward, driving the first connecting shaft 32 to rotate, driving the third spur gear 38 at the top to rotate, causing the second rack 37 at the top to move, driving the first rack 35 at the top to move, driving the second spur gear 34 to rotate, driving the first rack 35 at the bottom to move, driving the second rack 37 at the bottom to move, driving the third spur gear 38 at the bottom to rotate, driving the second connecting shaft 39 to rotate, driving the lower pressing plate 310 to rotate upward, compressing the first spring 36. When the raw materials fall on the two first crushing rollers 21, the first spring 36 resets, driving the second rack 37 and the first rack 35 at the top to move upward, driving the second rack 37 and the first rack 35 at the bottom to move downward, driving the third spur gear 38 to rotate in the reverse direction, driving the first connecting shaft 32 and the second connecting shaft 39 to rotate in the reverse direction, driving the top plate 31 to rotate upward, driving the lower pressing plate 310 to rotate downward. Under the action of the two lower pressing plates 310, the top of the raw materials is pressed downward, making it easier to crush the raw materials. The preliminarily crushed raw materials will fall into the feed funnel 47, then into the feeding trough 46. By rotating the pushing disk 51, the notch 52 is engaged with the protrusion 45, driving the feeding disk 44 to rotate, driving the feeding shaft 43 to rotate, driving the feeding roller 42 to rotate, so that the raw materials in the feeding trough 46 are evenly distributed on the second crushing roller 91.

[0069] By rotating the pushing shaft 74, the incomplete gear 73 is driven to rotate, driving the fourth spur gear 72 to rotate, driving the rotating rod 71 to rotate. Under the action of the spiral groove 75, the moving block 710 is driven to rotate. Under the action of the moving rod 77, the moving block 710 moves towards the wedge block 63, driving the moving rod 77 to move towards the wedge block 63, stretching the pushing spring 79, so that the pushing block 78 moves towards the wedge block 63, and the pushing block 78 slides on the inclined surface of the wedge block 63, pushing the wedge block 63 to move downward. The diameter of the incomplete gear 73 is larger than that of the fourth spur gear 72, but the number of teeth of the incomplete gear 73 is the same as that of the fourth spur gear 72. When the incomplete gear 73 rotates one circle, it can drive the fourth spur gear 72 to rotate one circle. And when the incomplete gear 73 is not engaged with the fourth spur gear 72, the fourth spur gear 72 stops rotating, and the moving block 710 slides from the spiral groove 75 into the straight groove 76. At this time, the pushing spring 79 resets, driving the moving rod 77 to move away from the wedge block 63, so that the moving block 710 moves away from the wedge block 63 in the straight groove 76. Since there is a certain distance between the pushing block 78 and the wedge block 63, when the rotating rod 71 rotates, the pushing block 78 is driven to move, but it has not yet slid on the inclined surface of the wedge block 63. That is, when the notch 52 is separated from the protrusion 45, the feeding tray 44 stops rotating, and one of the feeding grooves 46 just opens vertically downward. The wedge block 63 stops rotating, so that after the pushing block 78 travels this distance, it slides on the inclined surface, thereby pushing the wedge block 63 to move, driving the connecting rod 62 to move, and driving the scraping plate 61 to slide in the feeding groove 46, pushing the raw materials in the feeding groove 46 downward, so that the raw materials in the feeding groove 46 can all fall from the feeding groove 46, avoiding the raw materials sticking in the feeding groove 46 and affecting the feeding.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
