Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to an internal mixer mechanism for an inner tube production line. Background Art

[0002] Closed rubber mixer is also called internal mixer, which is mainly used for rubber plasticizing and mixing. Internal mixer is a machine with a pair of relatively rotating rotors of specific shapes, which plasticizes and mixes polymer materials intermittently under adjustable temperature and pressure.

[0003] In the prior art, when the rubber material passes through the gap between the rotors, the gap between the rotor and the upper and lower top bolts, and the gap between the inner wall of the mixing chamber, it will be sheared and broken by the ridges on the rotors, and stretched, deformed and kneaded together. However, the kneaded rubber material has strong adhesion, which makes it impossible for the horizontal discharging device to deliver all the kneaded materials. The residual material not only affects the subsequent mixing effect, but also causes damage to the internal machinery if it accumulates too much. Utility Model Content

[0004] The utility model aims to provide a mixing mechanism for an inner tube production line to solve the problem that the kneaded rubber materials have strong adhesion, so that the horizontal material discharging device cannot send out all the mixed materials, and the residual materials not only affect the subsequent mixing effect, but also cause damage to the internal machinery if too much accumulation occurs.

[0005] In order to achieve the above-mentioned purpose, a mixing mechanism for an inner tube production line is provided, including a conveying table, a support plate and a support block are fixedly connected to the top of the conveying table, a flip assembly for facilitating material discharge is arranged between the support plate and the support block, an internal mixing box is arranged above the conveying table, a pair of rotors are rotatably connected inside the internal mixing box, heating rollers are fixedly connected to the outer sides of the pair of rotors, ridges for shearing the rubber material are fixedly connected to the outer sides of the heating rollers, an electric push rod is fixedly connected to the top inner side of the support plate, and an extrusion plate is fixedly connected to the bottom end of the electric push rod.

[0006] As a further improvement of the present technical solution, the flipping assembly includes a rotating shaft rotatably connected between the support plate and the support block, a receiving block is fixedly connected to the outer side of the middle part of the rotating shaft, the mixing box is fixedly connected to the top of the receiving block, and a first servo motor coaxial with the rotating shaft is fixedly connected to the outer side of the support plate.

[0007] As a further improvement of the technical solution, one end of a pair of rotors extends to the outside of the mixing box and is fixedly connected to mutually meshing rotating gears. A pair of brackets is fixedly connected to the outside of the mixing box, and a second servo motor coaxial with one of the rotors is fixedly connected to the outside of the pair of brackets.

[0008] As a further improvement of the technical solution, a groove having the same arc surface as the heating roller is provided at the bottom end of the extrusion plate, and a track matching the convex ridge is provided inside the groove.

[0009] As a further improvement of the technical solution, a cavity is opened inside the extrusion plate, and a plurality of electric heating tubes for heating the bottom end of the extrusion plate are fixedly connected to the bottom end of the cavity.

[0010] As a further improvement of the technical solution, a controller is fixedly connected to the outer side of the support plate, and the electric push rod, the first servo motor, the second servo motor, the motor heat pipe and the heating roller are all electrically connected to the controller.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The mixing mechanism of the inner tube production line is provided with a flipping component so that the clumped rubber will fall onto the conveyor platform as the mixing box flips and is transferred to the next processing area. Since the rubber has a certain degree of adhesion, the second servo motor is turned on to drive a pair of rotors to rotate relative to each other, so that the convex edges on the outer sides of the rotors push the adhered rubber to fall off. The setting of the extrusion plate can avoid the problem of loosening of the connection between the machines due to long-term extrusion of the rubber or air pressure. The electric heating tube is provided to heat the bottom end of the extrusion plate, so that the rubber in contact with the extrusion plate can also be heated, thereby improving the mixing efficiency.

On the top of the connecting block 11, a first servo motor 12 coaxial with the rotating shaft 10 is fixedly connected to the outer side of the support plate 2, one end of a pair of rotors 5 extends to the outside of the mixing box 4 and is fixedly connected with a rotating gear 13 meshing with each other, a pair of brackets 14 are fixedly connected to the outer side of the mixing box 4, and a second servo motor 15 coaxial with one of the rotors 5 is fixedly connected to the outer side of the pair of brackets 14. A groove 16 with the same arc surface as the heating roller 6 is provided at the bottom end of the extrusion plate 9, and a track 17 matching the convex ridge 7 is provided inside the groove 16. A cavity 18 is provided inside the extrusion plate 9, and a plurality of electric heating tubes 19 for heating the bottom end of the extrusion plate 9 are fixedly connected to the bottom end of the cavity 18. A controller 20 is fixedly connected to the outer side of the support plate 2, and the electric push rod 8, the first servo motor 12, The second servo motor 15, the motor heat pipe and the heating roller 6 are all electrically connected to the controller 20. Before working, the raw materials such as the recycled rubber and the mixed rubber are first put into the mixing box 4. At this time, the electric push rod 8, the second servo motor 15, the heating roller 6 and the electric heating tube 19 are turned on by the controller 20. The opening of the electric push rod 8 drives the extrusion plate 9 to move downward until the convex rib 7 can run on the track 17 at the bottom of the extrusion plate 9. The opening of the second servo motor 15 drives one of the rotors 5 to rotate. Because the pair of rotors 5 are driven by a pair of mutually meshing rotating gears 13, the heating roller 6 and the convex rib 7 located inside the mixing box 4 are driven by a pair of rotors 5 and rotate in opposite directions, and the added raw materials are stirred and sheared. The setting of the pressing plate 9 can avoid the problem of loosening of the connection between the machines due to long-term exposure to the effects of rubber or air pressure. By setting the electric heating tube 19, the electric heating tube 19 is used to heat the bottom end of the extrusion plate 9, so that the rubber in contact with the extrusion plate 9 can also be heated, thereby improving the mixing efficiency. When the rubber is completed into a ball, the first servo motor is turned on by the controller 20 to drive the rotating shaft 10 to rotate between the support plate 2 and the support block 3. At this time, the mixing box 4 located at the top of the receiving block 11 is turned over, so that the balled rubber falls onto the conveying platform 1 and is sent to the next processing area. Because the rubber has a certain adhesion, the pair of rotors 5 rotate relative to each other, so that the convex ridges 7 on the outside of the rotor 5 push the adhered rubber to complete the shedding.

[0023] Working principle: Before work, raw materials such as recycled rubber and mixed rubber are placed in the mixing box 4. At this time, the electric push rod 8, the second servo motor 15, the heating roller 6 and the electric heating tube 19 are turned on by the controller 20. The opening of the electric push rod 8 drives the extrusion plate 9 to move downward until the ridge 7 can run on the track 17 at the bottom of the extrusion plate 9. The opening of the second servo motor 15 drives one of the rotors 5 to rotate. Because the pair of rotors 5 are driven by a pair of mutually meshing rotating gears 13, the heating roller 6 and the ridge 7 located inside the mixing box 4 are driven by a pair of rotors 5 to rotate in opposite directions, and the added raw materials are stirred and sheared. The setting of the extrusion plate 9 can avoid long-term exposure. In order to solve the problem that the connection between machines is easy to loosen due to the effects of rubber or air pressure extrusion, an electric heating tube 19 is set up to heat the bottom end of the extrusion plate 9, so that the rubber in contact with the extrusion plate 9 can also be heated, thereby improving the mixing efficiency. When the rubber is mixed into a ball, the first servo motor is turned on by the controller 20 to drive the rotating shaft 10 to rotate between the support plate 2 and the support block 3. At this time, the mixing box 4 located at the top of the receiving block 11 is turned over, so that the balled rubber falls onto the conveying table 1 and is sent to the next processing area. Because the rubber has a certain adhesion, a pair of rotors 5 rotate relative to each other, so that the convex ridges 7 on the outside of the rotor 5 push the adhered rubber to fall off.
