Abstract
The utility model discloses an underwater device for cutting plastic particles, mainly comprising a fastener, a cutter body, a particle cutting shaft sleeve, a driving shaft, a press cover, a bearing, a bearing base, a pressure plate, a coupler, a spring, a seal ring, a motor, a blade and a pelleting disc. The underwater device is characterized in that the waste plastic is heated to be the molten condition to be extruded, and cooled by cooling water, and a rotating cutter cuts the particles, so that the sizes of the particles can be achieved. The fastener is pressed on the cutter body, so that the reliability of the cutter body can be improved; and the back of the cutter body is provided with the spring with a certain standard, so that the sizes of the plastic particles can be guaranteed, the times for changing the cutter and the use level of blade can be reduced, and the device can save the blade by about 30% compared with the original structure. Due to the application of mechanical seal, the use environment of the motor and the bearing can be improved, the wear of the bearing and the motor can be reduced, and under the condition that the structure is not changed, the production efficiency can be improved by more than 30%, so that the underwater device for cutting the plastic particles is safe, reliable, economical and practical.
Description
Technical field
The utility model relates to a kind of plastic grain underwater cutpellet device.
Background technology
Reclaim waste or used plastics and carry out granulation again, exactly used waste or used plastics is reclaimed, fragmentation, heating, fusion, granulation are again cleaned in the waste or used plastics process classification to reclaiming then.And its underwater cutpellet device; At present existing structure be the axial feed of cutter hub be lean on the main frame hand at any time observation post's size of going out product adjust; And when adjustment, must be first shutdown, adjust through the adjustment screw then, reach the axial feed of cutter hub; So not only time-consuming but also take artificially, but also cannot say for sure to demonstrate,prove the size of particle.Connection between cutter hub and the pelletizing axle sleeve is the tapering that leans on them, and the connection precision of tapering is by its machining accuracy decision, and it is not tight often to cause cutter hub and pelletizing axle sleeve to be fitted because of machining accuracy is low in some small enterprises, and the cutter hub running is unstable, is prone to forge a knife.Hermetically-sealed construction is unreasonable besides, often makes the water inlet of motor and bearing, accelerates the wearing and tearing of motor and bearing.
Summary of the invention
To the problem that exists in the prior art, the utility model technical problem to be solved is to carry out in the production process of granulation again at the recovery waste or used plastics, and the reliability of assurance device and the size of product particle simultaneously, are improved the working environment of motor and bearing.
For reaching above-mentioned target, the present invention provides a kind of plastic grain underwater cutpellet device.It comprises securing member, cutter hub, pelletizing axle sleeve, power transmission shaft, gland, bearing, bearing block, platen, shaft coupling, spring, sealing ring, motor, blade, granulation dish; Power transmission shaft is through the driven by motor rotation by shaft coupling; Be to lean on tapering to connect between cutter hub and the pelletizing axle sleeve, also have securing member to compress, it is by the power transmission shaft driven rotary.
For guaranteeing the reliability of cutter hub on the pelletizing axle sleeve, on cutter hub, added securing member, and the hand of spiral of this securing member is left-handed, guaranteed the stationarity of cutter hub running.
For guaranteeing the size of particle.We improve pellet device, change screw adjustment into spring adjustment, in the back of cutter hub, pelletizing axle sleeve, are provided with the compression spring, by the axial force that the compression spring of certain specification comes the balance cutter hub, and the size of control particle.
Carry out to use cooling water in the production process of granulation again at the recovery waste or used plastics,, used the mechanical seal sealing ring for guaranteeing that cooling water does not seal in the bearing of motor and power transmission shaft; Improved the working environment of bearing and motor.
The effect that the utility model reached
A kind of plastic grain underwater cutpellet of the utility model device owing to the application of securing member, has improved the reliability of this device.The spring of certain specification is installed in the back of cutter hub, pelletizing axle sleeve, under the size that has guaranteed plastic grain, has reduced the use amount of number of changing knife and blade, save blade about 30% than original structure.Owing to the application of mechanical seal, improved the environment for use of motor and bearing, reduced the wearing and tearing of bearing and motor, under the situation that does not have to change in other structure, production efficiency has improved more than 30%.Facts have proved that it is a kind of safety, reliable, economical and practical plastic grain underwater cutpellet device.
Description of drawings
Fig. 1 is the structure chart of a kind of plastic grain underwater cutpellet of the utility model device.1 securing member, 2 cutter hubs, 3 pelletizing axle sleeves, 4 power transmission shafts, 5 glands, 6 bearings, 7 bearing blocks, 8 platens, 9 shaft couplings, 10 motors, 11 sealing rings, 12 springs, 13 blades, 14 granulation dishes.
The specific embodiment
A kind of plastic grain underwater cutpellet device of the utility model, it comprises securing member, cutter hub, pelletizing axle sleeve, power transmission shaft, gland, bearing, bearing block, platen, shaft coupling, spring, sealing ring, motor, blade, granulation dish.Power transmission shaft is through the driven by motor rotation by shaft coupling; The pelletizing axle sleeve is by the power transmission shaft driven rotary; Be to lean on tapering to connect between cutter hub and the pelletizing axle sleeve, and also have securing member pressing, it is by the power transmission shaft driven rotary; The distance of blade on the cutter hub in new and on the granulation dish is when the dress cutter, to confirm according to the size of particle; After using the regular hour, blade abrasion is along with the continuous wearing and tearing of blade; The resistance of pelletizing also increases thereupon; Simultaneously the elastic force of spring also strengthens thereupon, thereby guarantees the spacing between blade and the granulation dish, guaranteed go out the size of particle.
