Description

Rubber crushing device

Technical field

The utility model relates to compares disintegrating apparatus field, is specifically related to a kind of rubber crushing device.

Background technology

Rubber crushing machine is the necessary equipment utilizing waste or used plastics, rubber to carry out reclaiming granulation, it can be ground into fritter various plastics, rubber, and cleaning removes dust wherein while pulverizing, impurity, thus obtain clean clean rubber article, enable rubber industry wastewater machinery work well.

Carry out stripping and slicing and pulverize the equipment adopted being rubber crushing machine to waste old, traditional rubber crushing machine comprises frame, motor, decelerator, broken rubber roll, feeding mouth and discharging opening.Wherein broken rubber roll is arranged on support, and is made up of ditch roller initiatively and passive smooth roll; Feeding mouth is positioned at brokenly directly over rubber roll, and discharging opening is then positioned at brokenly immediately below rubber roll.

Chinese patent 201410657850.9 discloses one " rubber crushing machine breaks adhesive dispenser ", comprise and be installed on ditch roller in frame and smooth roll and roll body transmission mechanism by bearing block horizontal Tile, described ditch roller connects roll body transmission mechanism becomes drive roll, and described smooth roll is the driven voller of idle running; Described roll body transmission mechanism is the sprocket wheel chain reducing gear of driven by motor.Smooth roll is rotated after changing frictional force drive into, can speed discrepancy be produced between the ditch roller of pair roller and smooth roll, and speed ratio difference is larger, also larger to the mastication forces of sizing material generation in shear history, be conducive to the efficiency improving rubber chunk.But the setting of this structure, rubber is when carrying out brokenly glue, mostly old rubber inside is with stone, metal impurities, when entering brokenly broken glue process in adhesive dispenser, ditch roller with the interaction and impurities in old rubber, can make the cutting knife generation deformation on ditch roller, affects the follow-up use of ditch roller, and the replacing of ditch roller extremely bothers, the use of the broken adhesive dispenser of impact.

Detailed description of the invention

Referring to figs. 1 through Fig. 4, the utility model rubber crushing device embodiment is described further.

A kind of rubber crushing device, the breaker roll 2 comprising frame 1 and be arranged in frame 1, breaker roll 2 comprises ganoid smooth roll 21 and the rotor 22 with cutting knife, when carrying out brokenly glue to old rubber, first the old rubber of monoblock is put into above breaker roll 2, by the deflector roll that is oppositely arranged and smooth roll 21, old rubber is cut, make it be broken into the rubber of fritter, thus make the impurity of old rubber inside be more prone to removing, make old rubber better be realized recycling.Preferably, blade 23 and deflector roll removably connect, and deflector roll circumferential surface offer dovetail groove 221, blade 23 are provided with the fixture block 231 matched with dovetail groove 221.By dovetail groove 221 and the setting of fixture block 231, make blade 23 when being connected with rotor 22, what energy was stable is held in rotor 22, in rotor 22 rotation process, by the blade 23 that be connected stable with rotor 22, realize the cutting and crushing effect to old rubber, simultaneously when wearing and tearing occur blade 23, blade 23 can be pulled out from rotor 22, again new blade 23 is inserted from the dovetail groove 221 taken out, realize the replacing to blade 23, do not need to change whole rotor 22, can ensure the effect that rotor 22 cuts old rubber chunk equally, easy to maintenance.

Further, dovetail groove 221 is obliquely installed along rotor 22 surface, and preferably, dovetail groove 221 and deflector roll axial direction are that the angle of 3 °-5 ° is arranged.Dovetail groove 221 is obliquely installed, blade 23 distributes along dovetail groove 221, therefore blade 23 is also inclined to set on the surface of rotor 22, when being cut by rotor 22 pairs of rubber, because broken dissection is by mutually extruding between rotor 22 and smooth roll 21, make rubber fall between blade 23 and smooth roll 21, carry out fragmentation cutting by blade 23.Therefore blade 23 is obliquely installed, can make rotor 22 in rotation process, interaction point between blade 23 and smooth roll 21 is not axially acting in conjunction, namely in rotation process, contact point moves along blade 23, and the relative blade 23 that just makes produces the effect of cutting, makes old rubber can better carry out fragmentation cutting, obtain the rubber of little bulk, facilitate the recycling of rubber.

Preferably, the axis of smooth roll 21 and the axis of deflector roll in the same plane.When being delivered between smooth roll 21 and rotor 22 by old rubber, the interaction between smooth roll 21 and deflector roll can better be utilized, fragmentation cutting is carried out to old rubber.Smooth roll 21 and rotor 22 are all rotationally connected by bearing block 7 and frame 1.

Meanwhile, frame 1 is also provided with drive motors 5, drive motors 5 drives rotor 22 to rotate, and is also provided with reduction box 6 between drive motors 5 and rotor 22, can be controlled by reduction box 6 to the speed on drive motors 5 output valve rotor 22.Drive sprocket 3 chain 4 is also provided with between deflector roll and smooth roll 21.By the form that sprocket wheel 3 chain 4 rotates, the rotating in same direction that can realize between rotor 22 and smooth roll 21 makes the old rubber be delivered between smooth roll 21 and rotor 22 be subject to larger pullling active force, better realizes the fragmentation to old rubber.The transmission of sprocket wheel 3 chain 4, transmission between smooth roll 21 and rotor 22 can also be made more stable, by changing smooth roll 21 and the size of rotor 22 upper sprocket wheel 3 diameter, the speed of rotating between rotor 22 and smooth roll 21 can also be made to change, making it better realize cutting the fragmentation of old rubber.When cutting different rubber, because the performance of rubber itself is different, need to be realized by different active forces, and when relative rotation speed between smooth roll 21 from rotor 22 is different, what can change that rubber is subject to pulls power, thus uses the fragmentation of various performance rubber.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
