[0037] See also Figures 1 to 4 The utility model provides an open mixing mill, which includes a support seat 1, a roller 2, a material receiving tray 3 and a rolling support assembly 4.

[0038] There are two support seats 1 arranged in parallel; there are two rollers 2, which have the same height and are rotatably arranged between the two support seats 1. At least a part of the rolling support assembly 4 is located below the roller 2, and a receiving tray 3 for receiving the rubber material dropped during the rubber mixing process is placed on the rolling support assembly 4. In actual use, the receiving tray 3 can be transported to the front or rear of the mixing mill through the rolling support assembly 4, so that the production personnel can recover the rubber material in the receiving tray 3. The receiving tray 3 includes a bottom plate 31, a first baffle 32 vertically fixed on the bottom plate 31, and a second baffle 33 vertically arranged and detachably connected to the first baffle 32; the length direction of the second baffle 33 is consistent with the axial direction of the roller 2. The bottom plate 31 is used to receive the dropped rubber material; and the first baffle 32 and the second baffle 33 play a role in preventing the rubber material from falling to the outside of the receiving tray 3.

[0039] It can be understood that when the length direction of the second baffle 33 is consistent with the axial direction of the roller 2, the second baffle 33 is located at the front side or the rear side of the material receiving tray 3; and because the second baffle 33 is detachably connected to the first baffle 32, when the second baffle 33 is removed, a discharge port will be generated on the front side or the rear side of the material receiving tray 3, thereby facilitating the production personnel to clean the rubber on the bottom plate 31 of the material receiving tray 3 into the recovery box 7 below the discharge port (the recovery box 7 can be a cardboard box that is easy to carry).

[0040] Since a rubber compound conveying device is often provided on the front side of the open mill to convey the refined rubber compound to the next open mill or calender, in order not to affect the production operation of the production personnel on the front side of the open mill, preferably, when it is necessary to recover the rubber compound in the receiving tray 3, the rolling support assembly 4 conveys the receiving tray 3 to the rear of the open mill.

[0041] As Figure 3 shown, further, the horizontal cross-section of the first baffle 32 is U-shaped, and both ends of the second baffle 33 are inserted into the left side and the right side of the first baffle 32 respectively. The second baffle 33 can maintain an inserted relationship with the first baffle 32 in the vertical direction. In this case, when it is necessary to remove the second baffle 33, the second baffle 33 needs to be moved upward to separate from the first baffle 32.

[0042] More preferably, the first baffle 32 can maintain an inserted relationship with the first baffle 32 in the horizontal direction. In this case, when the receiving tray 3 moves to the rear side of the open mill, the production personnel can horizontally pull out the first baffle 32 from the left side or the right side of the receiving tray 3, so that the second baffle 33 is separated from the first baffle 32. Since the width of the receiving tray 3 is relatively wide, it is more convenient to horizontally pull the second baffle 33 than to move the second baffle 33 up and down.

[0043] As Figure 3 shown, further, slots 321 for inserting the second baffle 33 are provided on both the left and right sides of the first baffle 32. The slots 321 are U-shaped. A grip bar 5 is provided at the top of the second baffle 33, and the grip bar 5 is inverted U-shaped to facilitate the production personnel to perform the pulling operation on the second baffle 33.

[0044] As Figure 3 and Figure 4 shown, further, the top of the bottom plate 31 is inclined downward toward the direction where the second baffle 33 is located. Thus, after the rubber compound falls onto the bottom plate 31, it is easy to slide downward to the second baffle 33. After the second baffle 33 is removed, the cleaning difficulty of the rubber compound can be reduced.

[0045] It can be understood that the bottom of the bottom plate 31 still needs to be kept horizontal so that the receiving tray 3 can move.

[0046] As Figure 4 shown, further, the bottom plate 31 includes a first bottom plate 311 and a second bottom plate 312.

[0047] Among them, the first bottom plate 311 is horizontally arranged, and the first bottom plate 311 can be connected to the bottom of the first baffle 32 by welding. The second bottom plate 312 is inclined and fixed on the first bottom plate 311, and the lower end of the second bottom plate 312 can also be connected to the inner sides of the first bottom plate 311 and the first baffle 32 by welding.

[0048] It can be seen that when the above structure of the bottom plate 31 is adopted, the material used for the bottom plate 31 can be saved, thereby reducing the weight of the bottom plate 31 and making the material receiving tray 3 easy to handle (some rubber materials need to add pigments, so when the enterprise switches production, the material receiving tray 3 needs to be replaced and cleaned).

[0049] Such as Figure 1 、 Figure 2 and Figure 5 shown, further, the rolling support assembly 4 may include a frame 41, a plurality of roller rods 42 rotatably arranged on the frame 41, and a driving motor 43 for driving the roller rods 42 to rotate. The axial direction of the roller rods 42 is the same as the axial direction of the roller barrel 2, so that when the roller rods 42 rotate, the material receiving tray 3 can move along the front and back directions of the open mill; the roller rods 42 can be silicon carbide roller rods 42, which can withstand high temperatures, so that they can be used for a long time and are used to transport the material receiving tray 3.

[0050] By using the rotation of the roller rods 42 to automatically transport the material receiving tray 3, the labor intensity of production personnel can be reduced.

[0051] Such as Figure 2 shown, further, one end of the frame 41 extends to the rear side of the support base 1; the driving motor 43 is arranged on the frame 41 behind the support base 1, so that the driving motor 43 is far away from the high-temperature open mill, thereby prolonging the service life of the driving motor 43 and reducing the potential safety (fire) hazards of production.

[0052] Such as Figure 5 and Figure 6 shown, further, the output shaft of the driving motor 43 is connected to one of the roller rods 42; in order to make all the roller rods 42 rotate when the driving motor 43 works, the rolling support assembly 4 provided by the present invention further includes a chain transmission mechanism 44; the chain transmission mechanism 44 includes a sprocket 441 and a transmission chain 442; the sprocket 441 is fixedly arranged on the rotating shaft of the roller rod 42, and two parallel sprockets 441 on two adjacent roller rods 42 form a group; a transmission chain 442 is wound around each group of sprockets 441.

[0053] Compared with the way of using a flexible transmission belt for transmission, the transmission chain 442 is more resistant to high temperatures, and when the rolling support assembly 4 is used, serious safety hazards will not occur.

[0054] Such asFigure 2 As shown, further, a guiding assembly 6 is arranged inside the supporting seat 1; the guiding assembly 6 can be a vertically arranged guiding plate, or can be composed of the aforementioned guiding plate and a plurality of guiding wheels arranged inside the guiding plate (the axial direction of the guiding wheels is perpendicular to the horizontal plane). The guiding assembly 6 is located on both sides of the material receiving tray 3 and extends to the rear side of the supporting seat 1, so that it can be used to guide the material receiving tray 3, such that during the process of moving the material receiving tray 3 to the rear side of the open mill, the material receiving tray 3 Figure 2 will not shift in the left-right direction and the material receiving tray 3 can be normally conveyed back under the roller along the original path.

[0055] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
