Specific embodiments

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] The present utility model discloses a rubber mixing mill, as Figures 1-5 shown, including a chassis 1. Two material guiding plates 2 for guiding rubber are provided on the top surface of the chassis 1. Both of the two material guiding plates 2 are inclined towards the space between the two rotating rollers 402.

[0025] Two telescopic rods 102 are fixedly installed inside the storage cavity 101, and one end of the two telescopic rods 102 is commonly fixedly installed with a connecting plate 104. When the connecting plate 104 moves, the two telescopic rods 102 can be driven to expand and contract.

[0026] A spring 103 is fixedly installed on one side inside the storage cavity 101, and the spring 103 is fixedly connected to the connecting plate 104. When the connecting plate 104 moves towards the outside of the storage cavity 101, the spring 103 can be stretched.

[0027] On one side of the connecting plate 104, a first brush plate 105 is fixedly installed.

A pulley 109 is movably installed on the inner top surface of the storage cavity 101, and the pulley 109 is in contact with the traction rope 108. When the first electric push rod 107 drives the baffle 106 to rise, the traction rope 108 can pull the connecting plate 104 to move it outside the storage cavity 101, and then drive the first brush plate 105 to move outside the storage cavity 101.

[0028] The second brush plate 1052 is movably connected inside the first brush plate 105. A second electric push rod 1051 is fixedly installed inside the first brush plate 105, and the output end of the second electric push rod 1051 is fixedly connected to the second brush plate 1052. The second electric push rod 1051 can push the second brush plate 1052 to move. When the first brush plate 105 moves outside the storage cavity 101, the second electric push rod 1051 can push the second brush plate 1052 to move until the combined length of the first brush plate 105 and the second brush plate 1052 is the same as the length of the rotating roller 402.

[0029] Moving grooves 3 are provided on both sides of the outer surface of the chassis 1. Two moving blocks 4 are movably connected inside the two moving grooves 3, and the four moving blocks 4 can move inside the two moving grooves 3.

[0030] Two rotating shafts 401 are movably installed between the four moving blocks 4, and rotating rollers 402 are fixedly installed on the outer surfaces of the two rotating shafts 401. When the moving blocks 4 move, the rotating shafts 401 and the rotating rollers 402 can be driven to move to adjust the interval between the two rotating rollers 402.

[0031] Two first motors 5 are fixedly installed on one side of the four moving blocks 4, and the output ends of the two first motors 5 are respectively fixedly connected to the two rotating shafts 401.

[0032] A cylinder 403 is fixedly installed on the outer surface of the chassis 1 away from the first motor 5, and a driving plate 405 is fixedly installed at the output end of the cylinder 403. Two driving rods 404 are movably connected to the top surface of the driving plate 405, and the two driving rods 404 are respectively movably connected to the two moving blocks 4. When the cylinder 403 pushes the driving plate 405 to move up and down, the two driving rods 404 can drive two of the moving blocks 4 to move in opposite directions, and then the interval between the two rotating rollers 402 can be adjusted.

[0033] On both sides of the top surface of the chassis 1, movable slots 201 are provided. On one side of the interior of the two movable slots 201, a threaded rod 202 is movably connected.

Two sections of opposite threads are provided on the outer surface of the threaded rod 202. When the second motor 204 drives the threaded rod 202 to rotate, the two material guide plates 2 can be moved in opposite directions, so as to adjust the interval between the two material guide plates 2.

[0034] The working principle of the present utility model is as follows: Rubber falls between the two rotating rollers 402 through the two material guide plates 2, and the first motor 5 drives the rotating rollers 402 to rotate, so as to knead the rubber. After the processing is completed, the first electric push rod 107 can be started. The first electric push rod 107 drives the baffle 106 to rise, so that it is away from the storage cavity 101. When the baffle 106 rises, the traction rope 108 can pull the connecting plate 104 to move. The moving connecting plate 104 can stretch the spring 103. When the connecting block 203 moves, the first brush plate 105 can be driven to move, so that the first brush plate 105 moves to the outside of the storage cavity 101 and contacts the rotating roller 402, and then the surface of the roller 402 can be cleaned.
