[0025] The embodiment of the utility model provides a rubber mixing machine that is easy to clean, and the rubber mixing machine that is easy to clean is intended to solve the technical problems of the prior art that manual cleaning of the roller surface poses a safety hazard and is time-consuming and labor-intensive.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] A rubber mixing mill that is easy to clean, comprising a support frame 1, a front roller 2 being slidably connected to the top of the support frame 1, a rear roller 3 being rotatably connected to the top of the support frame 1 and located behind the front roller 2, two sets of sliding rods 4 being fixedly connected to the top of the support frame 1, and cleaning components 5 being slidably connected to the outer sides of the two sets of sliding rods 4;

[0028] First, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the specific structure of the cleaning component 5 is as follows:

[0029] The cleaning assembly 5 includes a sliding block 501, a rotating block 502, a telescopic rod 503, a hand-held handle 504 and a cleaning shovel 505. The sliding block 501 is slidably connected to the outer side of the sliding block 4, the rotating block 502 is rotatably connected to the outer side of the sliding block 501, the telescopic rod 503 is fixedly connected to the outer side of the rotating block 502, the hand-held handle 504 is fixedly connected to the end of the telescopic rod 503 away from the rotating block 502, the cleaning shovel 505 is fixedly connected to the end of the telescopic rod 503 away from the rotating block 502, and the cleaning shovel 505 is located below the hand-held handle 504.

[0030] During use, the present invention first holds the hand-held handle 504 with the hand, and drives the cleaning shovel 505 to press the roller surface of the front roller 2 or the rear roller 3 through the hand-held handle 504, and the hand-held handle 504 will drive the telescopic rod 503 to rotate. When the telescopic rod 503 rotates, it drives the rotating block 502 to rotate, and the sliding block 501 slides on the surface of the sliding rod 4, so that the cleaning shovel 505 can move left and right on the surface of the front roller 2 or the rear roller 3, and the telescopic rod 503 can be extended and retracted to facilitate the cleaning shovel 505 to clean the surface of the front roller 2 or the rear roller 3. During the cleaning process, the cleaning shovel 505 is pressed against the surface of the front roller 2 or the rear roller 3 by the hand-held handle 504, which can increase the safety when cleaning the roller surface.

[0031] Among them, see Figure 5 , a spring 6 is sleeved inside the rotating block 502, one end of the spring 6 is fixedly connected to the fixed block 7, and a blocking block 8 is fixedly connected to the outside of the sliding block 501 and at the end of the spring 6 away from the fixed block 7. When the telescopic rod 503 drives the rotating block 502 to rotate, the blocking block 8 is slidably connected to the rotating block 502, and the fixed block 7 is fixedly connected to the rotating block 502. The blocking block 8 will block the spring 6, so that the fixed block 7 squeezes the spring 6. When the external force on the rotating block 502 disappears, the spring 6 pushes the fixed block 7 in the opposite direction, and the fixed block 7 drives the rotating block 502 to rotate in the opposite direction. The rotating block 502 rotates in the opposite direction to reset the telescopic rod 503.

[0032] Further, please refer to the figure, the cleaning shovel 505 is fixedly connected to the telescopic rod 503 through a fixing card 9. The fixing card 9 can facilitate the disassembly and replacement of the cleaning shovel 505. An arc groove 10 is provided at the bottom of the cleaning shovel 505. The arc surface of the arc groove 10 coincides with the surface of the front roller 2, ensuring that the cleaning shovel 505 cleans more thoroughly and the diameters of the front roller 2 and the rear roller 3 are equal.

[0033] For further information, see Figure 1 、 Figure 2 、 Figure 3 and Figure 5Four groups of limiting slides 11 are fixedly connected to the outside of the slide rod 4, and sliding grooves 12 are opened on the inner side of the sliding block 501 at positions corresponding to the four groups of limiting slides 11. The limiting slides 11 are slidably connected to the sliding grooves 12. The cooperation between the limiting slides 11 and the sliding grooves 12 can limit the sliding block 501, so that the sliding block 501 will not rotate when sliding on the outside of the slide rod 4.

[0034] For further information, see Figure 1 、 Figure 2 and Figure 3 A placement rack 13 is fixedly connected to the top of the support frame 1 at a position corresponding to the telescopic rod 503. The placement rack 13 is adapted for use with the telescopic rod 503. When the cleaning component 5 is not in use, the placement rack 13 is used to support the telescopic rod 503, thereby supporting the cleaning component 5 so that the cleaning component 5 does not hinder the normal operation of the rubber mixer.

[0035] Also, see Figure 1 and Figure 2 The left and right ends of the front roller 2 are rotatably connected with sliders 14. A sliding hole 15 is opened at the top of the support frame 1 at a position corresponding to the slider 14. The slider 14 is slidably connected to the inner side of the sliding hole 15. The front end of the support frame 1 is threadedly connected with an adjusting bolt 16, and the rear end of the adjusting bolt 16 is rotatably connected to the slider 14. During use of the utility model, by rotating the adjusting bolt 16, the adjusting bolt 16 can drive the front roller 2 to slide on the inner side of the sliding hole 15, thereby adjusting the distance between the front roller 2 and the rear roller 3, thereby meeting the thickness adjustment during rubber mixing.

[0036] For further information, see Figure 1 、 Figure 2 and Figure 3 A motor 17 is fixedly installed on the right end of the support frame 1, and the output shaft of the motor 17 is fixedly connected to the rear roller 3. The motor 17 is used to drive the rear roller 3 to make the rubber mixer perform rubber mixing. The bottom end of the support frame 1 is located directly below the front roller 2 and the rear roller 3 and is movably connected with a receiving tray 18. The receiving tray 18 is used to receive the rubber film dropped during rubber mixing, and the receiving tray 18 is movably connected, which can facilitate the removal of the receiving tray 18 for cleaning.

[0037] The working process of this utility model:

[0038] During use, when the front roller 2 or the rear roller 3 needs to be cleaned, the hand-held handle 504 is first held by hand to move the cleaning assembly 5 out of the placement rack 13 as a whole, and then the hand-held handle 504 is used to drive the cleaning shovel 505 to press the roller surface of the front roller 2 or the rear roller 3. The hand-held handle 504 will drive the telescopic rod 503 to rotate, and when the telescopic rod 503 rotates, the rotating block 502 is driven to rotate, and the sliding block 501 slides on the surface of the sliding rod 4, so that the cleaning shovel 505 can be moved between the front roller 2 or the rear roller 3. The cleaning shovel 505 can move left and right on the surface of the front roller 2 or the rear roller 3, and the telescopic rod 503 can be extended and retracted to facilitate the cleaning shovel 505 to clean the surface of the front roller 2 or the rear roller 3. An arc groove 10 is provided at the bottom of the cleaning shovel 505, and the arc surface of the arc groove 10 coincides with the surface of the front roller 2, ensuring that the cleaning shovel 505 cleans more thoroughly. During the cleaning process, the cleaning shovel 505 is pressed against the surface of the front roller 2 or the rear roller 3 by the handheld handle 504, and there is no need for manual contact with the cleaning shovel 505, which can increase safety when cleaning the roller surface.
