DETAILED DESCRIPTION

[0025] The technical solution in the embodiment of the present application is to solve the problem that the filter holes of the above-mentioned filter grate will be partially blocked after long-term use, thereby causing the rubber powder to be screened slowly or even unable to be screened, affecting the production efficiency of the rubber powder. The overall idea is as follows:

[0026] See also Figure 1-Figure 7 , a crushing device includes a bracket 1 and a screen 15.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A receiving trough 2 is installed on one side of the bracket 1, and a crushing bin 3 is fixedly connected above the receiving trough 2. An inspection door 10 is installed on the front side of the crushing bin 3, so that the screen 15 can be replaced. A feed bin 4 is installed above the crushing bin 3, and a crushing and cutting piece 6 is installed inside the crushing bin 3. The two ends of the screen 15 are elastically connected with mounting plates 7. The two mounting plates 7 are installed on the inner wall of the crushing bin 3 below the crushing and cutting piece 6. A vibration motor 8 is installed on the bottom side of the screen 15. A spring 9 is connected to the opposite surface of the screen 15 and the mounting plate 7. When the recycled rubber is crushed, the vibration motor 8 and the crushing and cutting piece 6 are started in advance, and then the waste rubber is put into the crushing bin 3 through the feeding bin 4. The rubber is cut and crushed by the crushing and cutting piece 6 inside the crushing bin 3, and then sieved through the screen 15. After sieving, the rubber powder enters the receiving trough 2 for collection, storage and transportation to the next production link. Through the cooperation between the vibration motor 8 and the screen 15, when the screen 15 is sieving, the vibration motor 8 makes the screen 15 always in a vibrating state, which can accelerate the sieving of the screen 15 and prevent the screen 15 from being blocked, thereby improving the production efficiency of rubber powder.

[0028] One side of the feed bin 4 is hingedly connected to one side of the crushing bin 3, and the other side of the feed bin 4 and the other side of the crushing bin 3 are jointly provided with a connecting piece. The connecting piece includes a first connecting plate 13 and a second connecting plate 12, the first connecting plate 13 is connected to the feed bin 4, the second connecting plate 12 is connected to the crushing bin 3, and the first connecting plate 13 and the second connecting plate 12 are jointly screwed with a connecting bolt 14. When the crushing blade 63 is replaced after long-term use, the connecting bolt 14 is unscrewed from the first connecting plate 13 and the second connecting plate 12, and then the feed bin 4 is rotated open to expose the crushing blade 63, so as to achieve the replacement of the crushing blade 63.

[0029] A driving member 5 is installed on the bracket 1, and the driving member 5 is connected to the crushing and cutting member 6, and the driving member 5 drives the crushing and cutting member 6 to rotate. The crushing and cutting member 6 includes a rotating shaft 61, and the two ends of the rotating shaft 61 are respectively rotatably connected to the inner wall of the crushing bin 3, and a spiral plate 62 is installed on the rotating shaft 61, and a crushing blade 63 is installed on the spiral plate 62, and the driving member 5 is connected to the rotating shaft 61. The driving member 5 includes a driving motor 51, and the driving motor 51 is installed on the bracket 1. The output end of the driving motor 51 is fixedly connected to the driving shaft 52, and the rotating shaft 61 is located on the outer side of the crushing bin 3 and is fixedly sleeved with a driven shaft 53. The outer sides of the driving shaft 52 and the driven shaft 53 are connected to a transmission belt 54. Specifically, a protective cover 11 is provided on the outer side of the driving motor 51, the driving shaft 52, the driven shaft 53 and the transmission belt 54, and the two ends of the protective cover 11 are installed on the bracket 1 and the side wall of the crushing bin 3. When the rubber is crushed and cut, the driving motor 51 is started, and the driving motor 51 rotates to rotate the driving shaft 52, and the driven shaft 53 rotates under the action of the transmission belt 54, and then the rotating shaft 61 rotates, so that the crushing blade 63 rotates. When the crushing blade 63 rotates, the rubber can be cut and crushed. When the rubber powder in the crushing bin 3 that has not been screened by the screen 15 continues to be driven to rotate, it is continuously cut by the crushing blade 63 until it can be successfully screened.

[0030] See also Figure 1-Figure 7 The present application also provides a rubber powder production device, including

[0031] The above-mentioned crushing device can be used to cut and crush the rubber to facilitate subsequent production.

[0032] When using this application:

[0033] When the recycled rubber is crushed, the vibration motor 8 and the crushing and cutting element 6 are started in advance, and then the waste rubber is put into the crushing bin 3 through the feeding bin 4. The rubber is cut and crushed by the crushing and cutting element 6 inside the crushing bin 3, and then sieved through the screen 15. After sieving, the rubber powder enters the receiving trough 2 for collection, storage and transportation to the next production link. Through the cooperation of the vibration motor 8 and the screen 15, when the screen 15 is sieving, the vibration motor 8 makes the screen 15 always in a vibrating state, which can accelerate the screening of the screen 15 and prevent the screen 15 from being blocked, thereby improving the production efficiency of rubber powder.

[0034] In summary, the present application cooperates with the vibration motor 8 and the screen 15 so that when the screen 15 is sieving, the vibration motor 8 keeps the screen 15 in a vibrating state, which can accelerate the sieving of the screen 15 and prevent the screen 15 from being blocked, thereby improving the production efficiency of the rubber powder.
