Description

Technical Field

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

[0002] The production raw materials of environmentally friendly antibacterial ecological exterior wall coatings mainly include a variety of inorganic and organic components, which are designed to provide excellent environmental performance, antibacterial properties, and durability and weather resistance required for exterior walls. In terms of inorganic raw materials, shell powder, aluminum hydroxide, calcium oxide, magnesium silicate, zeolite powder, etc. are commonly used. These raw materials are not only environmentally friendly and non-toxic, but also provide excellent physical and chemical properties for coatings, such as hardness, wear resistance and weather resistance. Organic raw materials mainly include pure acrylic emulsion, styrene acrylic emulsion, surfactants, polyethylene glycol, polyvinyl alcohol, etc. These ingredients 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 give the coating antibacterial properties, a certain amount of antibacterial agents, such as nanosilver, silver ions, etc., will also be added. These antibacterial agents can effectively kill or inhibit the growth of microorganisms such as bacteria and molds, thereby keeping the exterior walls clean and hygienic. However, environmentally friendly antibacterial ecological exterior wall coatings require crushing equipment to crush the raw materials during the production process, and the existing crushing equipment still has the following defects: The material after crushing may have uneven particle size, which will directly affect the quality of the final product and affect the overall performance. Moreover, materials with uneven particle size may require more energy and time to be further processed in the subsequent processing to achieve the required particle size requirements. This not only increases production costs, but also reduces production efficiency. Moreover, during the mixing process, materials with uneven particle size will lead to slower mixing speed and reduced mixing uniformity. This may affect the overall performance and consistency of the product. In addition, during the grading process, materials with uneven particle size will lead to poor grading effect. The classifier may not be able to accurately separate materials of different particle sizes, thus affecting the subsequent processing. In addition, materials with uneven particle size may have poor fluidity problems during transportation and storage. This may cause the material to be blocked in the pipeline or storage tank, affecting the smooth progress of the production process. In addition, affecting production continuity, the uneven fineness of raw material crushing leads to frequent shutdowns to adjust equipment, seriously disrupting the original production plan, and significantly reducing the overall production efficiency and capacity stability. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] Example 1, reference Figure 1-Figure 9 , which is the first embodiment of the present invention, provides a raw material crushing equipment for the production of environmentally friendly antibacterial ecological exterior wall coatings, 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, and 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 assembly 3 installed on the crushing box 1 and the feed bin 11; the first crushing assembly 2 includes two first crushing rollers 21 rotatably connected to the crushing box 1 and meshing with each other, first spur gears 23 respectively sleeved on the rotating shafts of the two first crushing rollers 21, the two first spur gears 23 are meshed with each other, and a first drive motor 22 fixedly connected to the top of the rear side of the crushing box 1, and the output shaft of the first drive motor 22 is fixedly connected to the rotating shaft of one of the first crushing rollers 21.

[0022] Specifically, when in use, the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are put into the feed bin 11, and the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings enter the crushing box 1 through the feed bin 11, and the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are crushed through the crushing unit. After that, the crushed raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are discharged through the discharge port 12. The raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings can be pretreated through the pretreatment component, so that the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings can be crushed more easily. The feeding component allows the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings to be evenly sprinkled on the crushing unit, so that the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are crushed more evenly, and the particle size of the crushed material is uniform. The raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are uniformly crushed by the first crushing component 2. The raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are pressed down by the pressing component 3 during crushing, so that the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are easier to be crushed. The first driving motor 22 drives one of the first crushing rollers 21 to rotate, drives one of the first straight gears 23 to rotate, and then drives 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 opposite direction. Under the rotation of the two first crushing rollers 21, the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are preliminarily crushed, thereby reducing the difficulty of the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings in the crushing process.

[0023] Reference Figure 7 and Figure 8 The lower pressing assembly 3 includes two symmetrically distributed top plates 31 rotatably connected to the feed bin 11, two symmetrically distributed first connecting shafts 32 rotatably connected to the feed bin 11, the first connecting shafts 32 are fixedly connected to the corresponding top plates 31, two symmetrically distributed lower pressing plates 310 rotatably connected to the crushing box 1, two symmetrically distributed second connecting shafts 39 rotatably connected to the crushing box 1, the second connecting shafts 39 are fixedly connected to the corresponding lower pressing plates 310, and third spur gears 38 are respectively fixedly sleeved on the first connecting shafts 32 and the second connecting shafts 39. , two symmetrically distributed slides are respectively opened on the feed bin 11 and the crushing box 1, a limit frame 311 is slidably connected to the inner side of the slide, a first spring 36 is fixedly connected between the limit frame 311 and the inner wall of the slide, a second rack 37 is fixedly connected to the limit frame 311, a first rack 35 is fixedly connected to the second rack 37, a third spur gear 38 is meshed with the second rack 37, a fixed plate 33 is fixedly connected to the feed bin 11, a second spur gear 34 is rotatably connected to the fixed plate 33, and the second spur gear 34 is meshed with the first rack 35.

[0024] Specifically, when the raw materials for producing environmentally friendly antibacterial ecological exterior wall coatings enter the feed bin 11, the two top plates 31 are pressed down under the action of gravity, so that the two top plates 31 rotate downward to open 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 meshing with it 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, so that the second spur gear 34 rotates on the fixed 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 meshing with it to rotate, drive the second connecting shaft 39 to rotate, drive the limiting frame 311 at the bottom to slide, and squeeze the first spring 36 connected thereto. The two lower pressure plates 310 are rotated and opened upward, so that the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings can pass through the feed bin 11 and enter the crushing box 1. When the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings enter the crushing box 1, the first spring 36 is reset, driving the upper and lower limit frames 311 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 pressure plate 310 to rotate and reset. When the two lower pressure plates 310 are closed, the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings on the first crushing roller 21 are pressed downward, so that the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are easier to be crushed.

[0025] Reference Figure 9-Figure 16 The feeding components include 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 resetting assembly 8 installed in the feeding assembly 4; the feeding assembly 4 includes a feeding funnel 47 fixedly connected to the crushing box 1, two arc blocks 41 fixedly connected to the bottom of the feeding funnel 47 and symmetrically distributed, a feeding roller 42 rotatably connected between the two arc blocks 41, a plurality of feeding grooves 46 distributed in a ring array on the feeding roller 42, a feeding shaft 43 rotatably connected to the crushing box 1, a feeding plate 44 fixedly sleeved on the feeding shaft 43, and a plurality of protrusions 45 distributed in a ring array fixedly connected to the feeding plate 44.

[0026] Specifically, the pre-treated and crushed raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings will fall into the feeding funnel 47, and then part of the raw materials will fall into the feeding trough 46. The feeding plate 44 will rotate, driving the feeding shaft 43 to rotate, driving the feeding roller 42 to rotate, and driving the feeding trough 46 to rotate, so that the feeding trough 46 filled with raw materials will rotate downward, and the empty feeding trough 46 will rotate upward. When the feeding trough 46 rotates to open downward, the raw materials in the feeding trough 46 will fall under the action of gravity. At the same time, under the action of the two arc blocks 41, the raw materials in the feeding troughs 46 on both sides of the feeding roller 42 will not fall off, so that when the feeding roller 42 rotates, as long as the feeding trough 46 opens downward, the raw materials in the feeding trough 46 will fall, so that the raw materials can be evenly sprinkled on the crushing unit.

[0027] Reference Fig.10 The pushing assembly 5 includes a pushing shaft 53 rotatably connected to the crushing box 1, a pushing plate 51 fixedly sleeved on the pushing shaft 53, a notch 52 opened on the pushing plate 51, the notch 52 is respectively engaged with a plurality of protrusions 45, and a first belt 54 sleeved between the pushing shaft 53 and the rotating shaft of the first crushing roller 21.

[0028] Specifically, when the first crushing roller 21 rotates, it drives its rotating shaft to rotate. Under the action of the first belt 54, it drives the driving shaft 53 to rotate, drives the driving plate 51 to rotate, and drives the notch 52 to rotate. When the notch 52 engages with one of the protrusions 45, it drives the feeding plate 44 to rotate. When the notch 52 rotates and no longer engages with the protrusion 45, the feeding plate 44 stops rotating, so that the feeding plate 44 can rotate intermittently, driving the feeding roller 42 to rotate intermittently, so that the raw materials in the feeding trough 46 can fall completely.

[0029] Example 2, reference Fig.12 and Fig.13 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the scraper assembly 6 includes a scraper plate 61 slidably connected to the feeding trough 46, a slot opened at one end of the feeding roller 42, a connecting rod 62 slidably connected to the slot, one end of the connecting rod 62 extends into the feeding trough 46 and is fixedly connected to the scraper plate 61, and a wedge block 63 fixedly connected to the other end of the connecting rod 62.

[0030] Specifically, when the wedge block 63 moves, it drives the connecting rod 62 to move, drives the scraper plate 61 to slide in the feeding trough 46, and pushes the raw materials in the feeding trough 46 downward, so that the raw materials in the feeding trough 46 can all fall out of the feeding trough 46, avoiding the raw materials from sticking in the feeding trough 46 and affecting the feeding.

[0031] Reference Figure 13-Figure 15The pushing assembly 7 includes a rotating rod 71 rotatably connected to the crushing box 1, a fourth spur gear 72 fixedly mounted on the rotating rod 71, a pushing shaft 74 rotatably connected to the crushing box 1, an incomplete gear 73 fixedly mounted on the pushing shaft 74, the incomplete gear 73 meshing with the fourth spur gear 72, a spiral groove 75 provided on the rotating rod 71, a straight groove 76 provided on the rotating rod 71 and connected to 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, a pushing block 78 fixedly connected to one end of the moving rod 77, and the pushing block 78 being slidably connected to the inclined surface of the wedge block 63.

[0032] Specifically, the pushing shaft 74 rotates, driving the incomplete gear 73 to rotate, driving the fourth spur gear 72 to rotate, and 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 the number of teeth 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 meshed with the fourth spur gear 72, the fourth spur gear 72 stops rotating, and 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 toward the side of the wedge block 63, driving the moving rod 77 to move toward the side of the wedge block 63, stretching the pushing spring 79, so that the pushing block 78 moves toward the side of the wedge block 63. 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 from the spiral groove 75 to the straight groove 76. At this time, the pushing spring 79 is reset, 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 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 with 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. After walking this distance, the pushing block 78 slides with the inclined surface, thereby pushing the wedge block 63 to move. The rest of the structure is the same as that of Example 1.

[0033] Example 3, reference Fig.16, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the reset assembly 8 includes an active cavity 81 opened at the other end of the feeding roller 42, a reset rod 82 slidably connected in the active cavity 81, and a reset spring 83 fixedly connected between the reset rod 82 and the inner wall of the active 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 trough 46 and is fixedly connected to the scraper plate 61.

[0034] Specifically, when the scraper plate 61 moves toward the open end on the inner side of the feeding trough 46, it drives the reset rod 82 to move, thereby squeezing the reset spring 83. When the pushing block 78 no longer squeezes the wedge block 63, the reset spring 83 will reset, causing the reset rod 82 to move into the active cavity 81, driving the scraper plate 61 to move away from the opening of the feeding trough 46, thereby preventing the scraper plate 61 from staying at the opening of the feeding trough 46 and affecting the raw materials in the feeding funnel 47 from entering the feeding trough 46.

[0035] Reference Fig.17 The crushing unit also includes a second crushing assembly 9 arranged in the crushing box 1, and the second crushing assembly 9 includes two second crushing rollers 91 that are rotatably connected to the crushing box 1 and are meshed with each other, and fifth spur gears 92 that are fixedly mounted on the rotating shafts of the two second crushing rollers 91, respectively. The two fifth spur gears 92 are meshed with each other, and a second drive motor 93 is fixedly connected to the rear side wall of the crushing box 1. The output shaft of the second drive motor 93 is fixedly connected to the rotating shaft of one of the second crushing rollers 91, and a second belt 94 is mounted between the pushing shaft 74 and the rotating shaft of the second crushing roller 91.

[0036] Specifically, the second driving motor 93 drives one of the second crushing rollers 91 to rotate, drives one of the fifth spur gears 92 to rotate, drives the other fifth spur gear 92 to rotate in the opposite direction, drives the other second crushing roller 91 to rotate, so that the two second crushing rollers 91 rotate in the opposite direction, and the raw materials dropped from the feeding trough 46 are crushed again. When the second crushing roller 91 rotates, it drives the pushing shaft 74 to rotate through the second belt 94. The rest of the structure is the same as that of the second embodiment.

[0037] Example 4, reference Figure 1-Figure 17 , which is the fourth embodiment of the present invention, provides: a method for using a raw material crushing device for producing environmentally friendly antibacterial ecological exterior wall coatings, comprising the following steps: S1: Pour the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings into the feed bin 11. Under the action of gravity, the raw materials will press the two top plates 31 downward. Through the pressing assembly 3, the two pressing plates 310 press the raw materials downward, making the raw materials easier to be crushed.

[0038] S2: The raw materials after preliminary crushing will fall into the feeding funnel 47 and then into the feeding trough 46. The pushing component 5 drives the feeding plate 44 to rotate, so that the raw materials in the feeding trough 46 fall evenly onto the second crushing roller 91.

[0039] S3: By rotating 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, and the inclined surface of the wedge block 63 is slid, so that the wedge block 63 is driven to move, so that the scraper 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 the fourth spur gear 72, but the number of teeth of the incomplete gear 73 is the same as the number of teeth 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.

[0040] S4: When the scraper plate 61 moves, it drives the reset rod 82 to move and squeeze the reset spring 83. When the scraper plate 61 does not move, under the action of the reset spring 83, it drives the reset rod 82 to move into the active cavity 81 and reset.

[0041] Based on Examples 1-4, the working principle of the present invention is as follows: when in use, the raw materials for the production of environmentally friendly antibacterial ecological exterior wall coatings are poured into the feed bin 11. Under the action of gravity, the raw materials will press the two top plates 31 downward, 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 pressure plate 310 to rotate upward, squeezing the first spring 36. When the raw materials fall on the two first crushing rollers 21, the first spring 36 is reset, 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 opposite direction, driving the first connecting shaft 32 and the second connecting shaft 39 to rotate in the opposite direction, driving the top plate 31 to rotate upward, driving the lower pressure plate 310 to rotate downward, under the action of the two lower pressure plates 310, the top of the raw material is pressed down, making it easier to crush the raw material, and the raw material after preliminary crushing will fall into the feed funnel 47 and into the feeding trough 46, and by rotating the push plate 51, the notch 52 is engaged with the protrusion 45, driving the feeding plate 44 to rotate, driving the feeding shaft 43 to rotate, driving the feeding roller 42 to rotate, so that the raw material in the feeding trough 46 falls evenly on the second crushing roller 91.

[0042] By rotating the pushing shaft 74, the incomplete gear 73 is driven to rotate, the fourth spur gear 72 is driven to rotate, and the rotating rod 71 is driven 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 toward the side of the wedge block 63, and the moving rod 77 is driven to move toward the side of the wedge block 63, and the pushing spring 79 is stretched to make the pushing block 78 move toward the side of the wedge block 63, so that 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 the fourth spur gear 72, but the number of teeth of the incomplete gear 73 is the same as the number of teeth 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 moves from the spiral groove 75. The pusher 78 then moves away from the wedge block 63, and the pusher 710 moves away from the wedge block 63 in the straight groove 76. Since there is a distance between the pusher block 78 and the wedge block 63, when the rotating rod 71 rotates, the pusher block 78 is driven to move, but it has not yet slid with 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 troughs 46 just opens vertically downward, and the wedge block 63 stops rotating, so that the pusher block 78 slides with the inclined surface after traveling this distance, and then pushes the wedge block 63 to move, drives the connecting rod 62 to move, drives the scraper plate 61 to slide in the feeding trough 46, and pushes the raw materials in the feeding trough 46 downward, so that the raw materials in the feeding trough 46 can all fall from the feeding trough 46, avoiding the raw materials sticking to the feeding trough 46 and affecting the feeding.
