Summary of the invention:

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and seek to design a rubber mixing mill rubber turning device, which can perform grade stacking under the premise of continuous rubber turning, further promote grade mixing of rubber materials and improve mixing effect.

[0004] In order to achieve the above-mentioned purpose, the main structure of the rubber turning device of the rubber mixing mill involved in the present invention includes a transmission belt, an active roller, a driven roller, a turning roller, a pressure roller, a stop roller and a guide roller; the transmission belt is installed on the active roller and the driven roller, and an inclined turning roller and a pressure roller are arranged above the transmission belt.

[0006] The transmission belt involved in the present invention is a horizontal transmission belt, which provides active friction force for the film and drives the film to move horizontally.

[0007] The active roller involved in the present invention moves with the transmission belt.

[0008] The intermediate roller involved in the present invention has the function of reinforcing the structure.

[0009] The number of the rubber turning rollers involved in the present invention is 2, the central axes of the two are coplanar, the central axes are parallel to the upper surface of the conveyor belt, and the plane where the central axes are located is perpendicular to the upper surface of the conveyor belt, so as to facilitate manufacturing and assembly. The movement direction of the rubber turning roller and the movement direction of the conveyor belt are 0-45°, and the smaller the angle, the better, so as to achieve the effect of oblique rubber turning and make the rubber material slide between the front roller and the rear roller of the open mixing mill arranged below; the diameter of the rubber turning roller is 2-3cm, and it can rotate actively. The gap width between the rubber turning roller and the conveyor belt and between the two rubber turning rollers is 2-3mm, which is larger than the width of the gap between the front roller and the rear roller of the open mixing mill (0.5-1mm), so as to prevent the film from being stuck by the rubber turning roller and unable to turn the rubber; the rotation direction of the rubber turning roller is the same as that of the active roller, and the rubber turning roller blocks the horizontal movement of the film, so that the film is automatically rolled under the dual friction of the conveyor belt and the rubber turning roller, thereby realizing the series mixing during rubber turning.

The pressing roller cooperates with the middle roller to control the height of the pressed film.

[0011] The blocking roller of the present invention is closely attached to the boundary of the transmission belt and is symmetrical with respect to the transmission belt, so as to limit the width of the extruded film and facilitate the turning of the film by the turning roller.

[0012] The top surface of the guide roller of the present invention is flush with the upper surface of the transmission belt to prevent the rubber material from adhering to the front end of the transmission belt in a large area and interfering with the movement of the active roller.

[0013] Compared with the prior art, the present invention mainly comprises a conveyor belt and a rubber turning roller. The conveyor belt can transport the film, the rubber turning roller can turn the film and make the film into a roll. The rubber turning roller forms a certain angle with the moving direction of the conveyor belt, so that the film is rolled obliquely, and the rolled rubber material slowly slides from one side of the conveyor belt into the open mixing mill below. The present invention also comprises guide rollers, pressure rollers, stop rods and other components to limit the shape of the film. The present invention has a simple structure and is easy to operate. It can not only make the rubber material in continuous motion realize graded stacking to promote mixing, but also can turn the rubber material continuously, and has a good mixing effect, can reduce the labor intensity of operators, and has a good prospect for promotion and application.

[0018] The present invention is further described below by way of implementation examples in conjunction with the accompanying drawings.

[0019] Embodiment 1:

[0020] The main structure of the rubber mixing mill rubber turning device involved in this embodiment includes a transmission belt 1, an active roller 2, a driven roller 3, an intermediate roller 4, a rubber turning roller 5, a pressure roller 6, a stop roller 7, a stop roller fixing frame 8 and a guide roller 9; the transmission belt 1 with an annular belt structure is installed on the active roller 2 and the driven roller 3 with a cylindrical structure, one end of the active roller 2 is set as the front end, and one end of the driven roller 3 is set as the rear end, and a cylindrical intermediate roller 4 is also arranged between the active roller 2 and the driven roller 3, and the intermediate roller 4 is close to the active roller 2. The upper part of the transmission belt 1 is provided with inclined rubber turning rollers 5 arranged in pairs and a cylindrical pressure roller 6 corresponding to the intermediate roller 4. The movement direction of the rubber turning roller 5 forms an angle of 0-45 degrees with the movement direction of the transmission belt 1, and the smaller the angle, the better. Two cylindrical stop rollers 7 parallel to each other are arranged in front of the transmission belt 1, and the top of the stop roller 7 is connected by a rectangular plate-shaped stop roller fixing frame 8, and a cylindrical guide roller 9 is arranged in front of the stop roller 7, and the width of the guide roller 9 is greater than the width of the transmission belt 1.

[0021] The rubber mixing mill rubber turning device involved in this embodiment is used in conjunction with the mixing mill 10, the active roller 2, the rubber turning roller 5 and the pressure roller 6 rotate normally, the movement direction of the conveyor belt 1 is axially perpendicular to the movement direction of the front roller 101 and the rear roller 102 of the mixing mill 10 below, the rotation direction of the active roller 2 is the same as the rotation direction of the front roller 101 of the mixing mill 10, and the upper surface of the conveyor belt 1 moves backward with the rotation of the active roller 2; first, a section of rubber is quickly cut from the front roller 101 of the mixing mill 10, and this section of rubber is the unrolled rubber 100, which is still connected to the rubber on the mixing mill 10; then the unrolled rubber 100 is quickly placed around the guide roller 9 on the upper surface of the front end of the conveyor belt 1, and the unrolled rubber 100 is brought into the two ends under the friction of the conveyor belt 1. The rubber sheet is squeezed between the two stop rollers 7 through the gap between the pressure roller 6 and the upper surface of the conveyor belt 1 to form a rubber sheet. At this time, the vertical cross-section of the rubber is a rectangle, the width is the distance between the two stop rollers 7, and the height is the distance between the pressure roller 6 and the upper surface of the conveyor belt 1. When the squeezed rubber sheet moves to the rubber turning roller 5, it is blocked by the rubber turning roller 5. Under the dual friction between the upper surface of the conveyor belt 1 and the rubber turning roller 5, the rubber sheet moves upward and is curled into a rolled rubber sheet 200 with a cylindrical structure. With the movement of the conveyor belt 1 and the rotation of the rubber turning roller 5, the rolled rubber sheet 200 slides vertically from the upper surface of the conveyor belt 1 to between the front roller 101 and the rear roller 102 of the mixing mill 10, and reaches the conveyor belt 1 again under the action of friction, completing a working cycle, thereby realizing the graded mixing of the rubber sheet.

[0022] When the rubber mixing mill rubber turning device involved in this embodiment is used, rubber materials of different colors are repeatedly fed into the conveyor belt 1 and the mixing mill 10, and the number of layers of the obtained rolled rubber material 200 increases exponentially. For example, the number of layers of the rubber sheet that completes the first cycle is 5, and the cross-section is as follows Figure 3 As shown, the number of layers of the film that completes the second cycle is 25, and the cross section is Figure 3 The number of layers of the film that completes the third cycle is 125, and the cross section is Figure 3 Cubed, and so on.
