Specifically, the rubber processing and mixing equipment provided in the embodiment adopts a roll-in-roll plasticating method for plasticating raw rubber materials to obtain plasticated rubber with better plasticity. The two opposite supports 1 are used for supporting each roller, except the supports 1, the embodiment further comprises a motor 5, a speed reducer 6 and a speed ratio gear 7 which are shared by the prior art, the motor 5, the speed reducer 6 and the speed ratio gear 7 are sequentially connected in a transmission mode, and a base used for supporting, the speed ratio gear 7 is in transmission connection with the first roller 2 and the second roller 4, so that the first roller 2 and the second roller 4 rotate relatively at a certain rotation speed ratio, a rubber material is extruded and sheared in a rubber mixing gap between the first roller 2 and the second roller 4, the rubber material is coated on the first roller 2, a roll-coating plasticating (the prior art is omitted), a pre-pressing gap is formed between the pre-pressing roller 3 and the first roller 2, the pre-pressing gap is located at the upstream of the rubber mixing gap, the rubber material is pre-pressed once before plasticating, the thickness of the rubber material is greatly reduced, and the rubber material thinned later smoothly enters the rubber mixing gap for rubber mixing. The width of the pre-pressing gap is wider, but not more than 10mm, so that the rubber material can be conveniently coated on the first roller 2; the width of the rubber mixing gap is narrower but not smaller than 0.5mm, so that the rubber material can be ensured to have better extrusion force and shearing force. The working principle of the rubber processing and mixing device provided in this embodiment is that firstly, an initial raw rubber material is placed on a pre-pressing gap between a pre-pressing roller 3 and a first roller 2, the pre-pressing roller 3 and the first roller 2 pre-press the initial rubber material, the initial rubber material is brought into the pre-pressing gap under the action of friction force and then discharged, the thickness of the rubber material is greatly reduced after the pre-pressing, then the rubber material falls into or is brought into a rubber mixing gap between the first roller 2 and a second roller 4 by the first roller 2, the rubber material is extruded and sheared, then the extruded rubber material is coated on the first roller 2, because the pre-pressing gap between the pre-pressing roller 3 and the first roller 2 is wider, the coating can be smoothly completed, and then the coated rubber material enters the rubber mixing gap for extrusion and shearing along with the rotation of the first roller 2. In the prior art, when the rubber material is subjected to roll-covered plasticating, in order to conveniently realize the coating of the rubber material, the roll gap of the two rollers is larger in an initial stage, and the plastic rubber with better plasticity is obtained, so that the roll gap of the two rollers needs to be reduced again or repeatedly in a later stage, thereby increasing the plasticating time, reducing the working efficiency and increasing the energy consumption. The main innovation point of the invention is that the roll gap between the first roller 2 and the second roller 4 can be smaller in the initial stage while the roll-covered plastication can be realized, and the roll gap of the two rollers does not need to be reduced again in the later stage, or the times of reducing the roll gap for a plurality of times can be reduced.
In this embodiment, by adding the pre-pressing roller 3, and the pre-pressing gap formed between the pre-pressing roller 3 and the first roller 2 is larger than the rubber mixing gap between the first roller 2 and the second roller 4, so that the rubber material is extruded with the pre-pressing gap with larger width, and then smoothly enters the rubber mixing gap with smaller width after being thinned, and the rubber material is extruded and sheared, because the pre-pressing gap between the pre-pressing roller 3 and the first roller 2 is wider, the rubber material can be conveniently coated on the first roller 2, and meanwhile, the rubber mixing gap with smaller width between the second roller 4 and the first roller 2 can keep better extrusion force and shearing force on the rubber material.
In the embodiment, in one rotation period of the first roller 2, the rubber material can be extruded with different forces twice, so that the breaking efficiency of macromolecular chains in the rubber material is improved, and the rubber material has a higher rubber mixing effect when rubber is mixed in one rotation period.
In this embodiment, the pre-pressing roller 3 is in transmission connection with the second roller 4, so that the second roller 4 will drive the pre-pressing roller 3 to rotate in a following manner when rotating. When the sizing material is pre-extruded, the sizing material enters into a pre-extrusion gap and is extruded by the pre-extrusion roller 3 and the first roller 2, and meanwhile, the pre-extrusion roller 3 and the first roller 2 are sheared, so that in one rotation period of the first roller 2, the sizing material can be extruded twice with different forces, and simultaneously, the sizing material can be sheared twice with different forces, the breaking efficiency of macromolecular chains in the sizing material can be further improved, the blending uniformity of all components in the sizing material is improved, and the rubber mixing effect is better.
Further, a first gear 11 is fixedly installed on a rotating shaft of the pre-pressing roller 3, a second gear 12 is fixedly installed on a rotating shaft of the second roller 4, and the first gear 11 and the second gear 12 are in transmission connection through a first chain. The transmission connection of the gears and the chains is utilized, so that the second roller 4 and the pre-pressing roller 3 can synchronously rotate, and the second roller 4 and the first roller 2 synchronously rotate, so that the pre-pressing roller 3 and the first roller 2 synchronously rotate, the extrusion force and the shearing force of the sizing material can be synchronously carried out when the sizing material is pre-extruded, the phenomenon that the shearing force is postponed or the shearing force intermittently disappears can not occur, and the shearing time and the shearing effect of the pre-pressing roller 3 and the first roller 2 on the sizing material are ensured.
Still further, the top height of the pre-compression roller 3 is higher than the top height of the first roller 2. Because the operator stands in front of the first roller 2 when operating, the sight line is opposite to the first roller 2, when the height of the pre-pressing roller 3 is higher than that of the first roller 2, the operator can conveniently observe the pre-pressing roller 3, so that the sight line can more clearly see the position of the pre-pressing gap, and the sight line can accurately place sizing materials; and the higher pre-pressing roller 3 can block the sizing material, so that the sizing material accumulated above the pre-pressing roller 3 and the first roller 2 is prevented from sliding out from the rear of the pre-pressing roller 3.
In this embodiment, the diameters of the pre-pressing roller 3 and the second roller 4 are smaller than the diameter of the first roller 2, and the diameters of the pre-pressing roller 3 and the second roller 4 are controlled within an effective range, so long as the rubber material is not affected to enter the pre-pressing gap and the rubber mixing gap to realize rubber mixing. Because the width in the rubber mixing gap is less than the width in the pre-compaction gap, the rubber material can be accumulated from the pre-compaction gap to the rubber mixing gap, and the diameters of the pre-compaction roller 3 and the second roller 4 are less than those of the first roller 2, so that the distance between the pre-compaction roller 3 and the second roller 4 can be increased, and meanwhile, the top height of the pre-compaction roller 3 is higher than that of the first roller 2, the distance between the pre-compaction roller 3 and the second roller 4 can be further increased, and the accumulation space between the pre-compaction roller 3 and the second roller 4 can be increased, so that the situation of blocking caused by excessive accumulation of the rubber material is not easy to occur.
Further, be provided with between pre-compaction roller 3 and the second roller 4 and block the area, it is used for blockking to be located between pre-compaction roller 3 and the second roller 4 accumulational sizing material, prevent accumulational sizing material roll-off from between pre-compaction roller 3 and the second roller 4, simultaneously, it can lead to the sizing material between pre-compaction roller 3 and the second roller 4 to block the area, make sizing material accurately enter into the rubber mixing clearance between first roller 2 and the second roller 4 smoothly, block and enclose into the buffer space between area, first roller 2, pre-compaction roller 3 and the second roller 4, the buffer space is used for holding accumulational sizing material between pre-compaction roller 3 and the second roller 4, buffer space's size mainly depends on the interval between pre-compaction roller 3 and the second roller 4, when increasing the interval between pre-compaction roller 3 and the second roller 4, can increase buffer space, thereby improve the accommodation to sizing material.
In this embodiment, the blocking belt is a conveying belt 10, the conveying belt 10 is sleeved on two driving cylinders 21 which are arranged up and down, the two driving cylinders 21 are rotationally connected with the bracket 1, a third gear 20 is fixedly installed on a rotating shaft of the driving cylinder 21 positioned below, a fourth gear 13 is fixedly installed on a rotating shaft of the second roller 4, and the third gear 20 and the fourth gear 13 are in transmission connection through a second chain. The transmission of the second chain enables the transmission cylinder 21 positioned below to synchronously rotate along with the rotation of the second roller 4, and the rotation of the transmission cylinder 21 positioned below drives the transmission belt 10 to rotate. Because when plasticating sizing material, there is garrulous little sizing material piece to drop, and the sizing material piece that drops in the pre-compaction clearance can directly drop to the conveyer belt 10 and collect, and is very convenient, utilize the rotation of conveyer belt 10 can conveniently remove the piece of collecting to the rubber clearance in to mix with other sizing materials, can not cause the waste of sizing material.
Further, the vertical center line of the transmission cylinder 21 located below is staggered from the vertical center line of the second roller 4, and the vertical center line of the transmission cylinder 21 located below is closer to the first roller 2. By the aid of the design, the rubber material in the buffer space can be located on one side, close to the first roller 2, of the vertical center line of the second roller 4, and accordingly the rubber material can enter the rubber mixing gap more smoothly.
Still further, the two transmission drums 21 are staggered from each other, and the transmission drum 21 located below is closer to the first roller 2. This arrangement allows the conveyor belt 10 to be inclined, thereby increasing the buffer space and increasing the rate of storage for the sizing material.
