Technical field
The present invention relates to a kind of pulverizer that can prevent the vibrations of the drive division that load change causes when pulverizing object being treated, and be used to prevent the drive division installation method that shakes.
Background technology
For solving the problems such as increase of environmental pollution or trade waste, form circular form society and become important day by day.For example, make in the moulding factory of moulding product or moulding parts as the synthetic resin of representative with plastics using, do not need part or the bad moulding product etc. that are called runner waste material (sprue runner) that produce during to moulding reclaim, and improve the resource reutilization rate of resin material.
In the recovery of resin material, with the runner waste material that is recovered to pulverizer be ground into prescribed level crushing piece and as reclaiming resource.This pulverizer to be pulverized cutter by wedging in order making easily from the runner waste material that drops into the hopper input, and at first to be carried out coarse crushing with the coarse crushing cutter, and the material of coarse crushing is ground into the crushing piece of regulation particle shape again with the pulverizing cutter.With the coarse crushing cutter with pulverize 1 shaft type pulverizer on the cutter stuck-at-rotating shaft, the driver part number that drives rotating shaft is less, construct also simple, therefore quilt much enterprises be used for recovery in the factory.
This pulverizer is roughly case construction, and at the relative position place on one side of casing roughly, separate configuration has 1 pair of fixed sidewall, by bearing (bearing) axle rotating shaft is arranged in the substantial middle portion of each fixed sidewall.Interval and configuration with regulation on the rotating shaft are embedded with a plurality of coarse crushing cuttves, between fixed sidewall and the coarse crushing cutter, and are embedded with a plurality of pulverizing cuttves between each coarse crushing cutter.Roughly the subtend position of the another side of casing disposes and can swing sidewall around 1 couple of the swinging axle swing parallel with rotating shaft.By each fixed sidewall and respectively swing sidewall and constitute shell.
Inboard at side swing sidewall is fixed with dead knife.Dead knife is ground into the runner waste material by moving with the association that pulverizes cutter the crushing piece of regulation particle shape, and makes the runner waste material be pulverized the cutter wedging easily by moving with the association of coarse crushing cutter.In addition, the opposing party swings the inboard of sidewall, is fixed with to be used for and will to pulverize under the crushing piece rake that cutter pulverizes and the scraper of discharging in assigned position.
The deceleration device that is provided with the chimeric output shaft of rotating shaft has been installed in the outside of one side's fixed sidewall.The downside of deceleration device is provided with electro-motor, and the driving shaft of electro-motor is rotated, and via driven wheel output shaft and rotating shaft is driven to the direction of rotation of stipulating.The two ends of output shaft are propped up on the framework of deceleration device by axle by bearing (bearing).

Therefore, a kind of like this pulverizer (frittering off line) has been proposed: be equipped with to have and be arranged on supporting axis on the fixed sidewall abreast with rotating shaft, and reaching state mobile on the diameter of axle direction by nested in the axial of this supporting axis, and be fixed on the supportive device of the support plate on the deceleration device, by this supportive device with speed brake setting on fixed sidewall, like this, be fixed on the deceleration device support plate with the rotating shaft be the center axially on have the headroom of swing, therefore bearing can not be applied in excessive power, thereby can prevent that damage of bearings or bearing life from shortening (with reference to patent documentation 1).
Patent documentation 1:JP spy opens the 2005-329295 communique
But, in the pulverizer of patent documentation 1, in the crushing process of object being treated, acting on the power of pulverizing cutter and coarse crushing cutter by dead knife changes according to the pulverizing situation, therefore, by rotating shaft and be nested in output shaft on the rotating shaft, in deceleration device, produce the torque of change, exist torque to make that the support plate that is fixed on the deceleration device is the problem that the center is shaken with the supporting axis because of this change.
Therefore, adopted in the assigned position of the metal system bearing of securing shredder carriage has been set, between carriage and support plate, the shock-resistant member that polyurethane rubber is for example made is set, push shock-resistant member with carriage, prevent a kind of like this method of the vibrations of deceleration device and electro-motor etc. thus.But have following problem: the installation that is used for pushing the carriage of shock-resistant member needs the space, and the space that is provided with of pulverizer increases; Under situation, adjust pressure by the minute movement of carriage, so there is deviation in pressure because of operator's difference with carriage pushing shock-resistant member; Polyurethane rubber worsens because of the time is long, so even in the early stage the stage can prevent the vibrations of deceleration device and electro-motor etc., but between the operating period long after, just be easy to generate vibrations.More than the expectation of these problems be resolved.
Summary of the invention
The present invention makes in view of above-mentioned condition, its objective is provides a kind of installing space that does not need carriage, can reduce the space that is provided with of device, prevent damage of bearings, the lost of life, can not be subjected to the pulverizer of the vibrations that restrictedly prevent drive divisions such as deceleration device and electro-motor of useful life by simple structure, and the installation method of drive division.
