Abstract

The utility model discloses a novel hot granulator which comprises a cutter arbor, wherein a cutter seat is arranged at the front end of the cutter arbor and is in ball joint with the cutter plate; a hot granulating cover is arranged outside the cutter seat and the cutter plate; a bearing support is arranged in the middle of the cutter arbor; the tail end of the cutter arbor and the output shaft of a granulating motor are connected with each other through a universal joint; the bearing support and the granulating motor are fixed to an underframe sliding seat; and the sliding rod of the underframe sliding seat is parallel to the cutter arbor. The novel hot granulator can ensure that a plurality of cutters are closely clung to a machine head mold plate and the granulating effect is good; the service life of the bearing support is long; the error requirement of centering of the central point of the cutter arbor and the central point of the granulating motor is small; and the cutters are convenient to mount and adjust.

Description

Novel hot cut pellet machine

Technical field

The utility model relates to the device of cutting raw material in the plastic industry, especially a kind of hot cut pellet machine.

Background technology

Die face earnestly is the granulation mode a kind of commonly used of plastic granulator, and the hot cut pellet machine that generally uses at present mainly contains two kinds of structures:

1) bearing spider of cutting knife dish is installed on the handpiece body, and knife bar is connected with motor output shaft by universal joint.The shortcoming of this structure is: bearing spider is installed in handpiece body, because the temperature of handpiece body is between 200～350 ℃, its heat can pass to bearing, and the service life of cutting knife dish bearing is very short; Guarantee the pelletizing effect, it is closely connected to make cutting knife and head touch plate, and the cutting knife dish leans on the elastic force of spring to do axially-movable along bearing spider, does not have the universal adjustment function, is difficult to guarantee that several to touch plate to cutting knife while and head closely connected, influences the pelletizing effect; Knife bar is a single point supporting, beats very greatly with the universal joint link when rotated, and the service life of universal joint bearing pin is very short.

2) motor is directly installed on the bearing block of hot cut pellet cover, and motor, bearing block, hot cut pellet cover are one.Advantage is: bearing block is away from the handpiece body of high temperature, and the cutting knife dish is connected with the Cutter apron ball-type, and the cutting knife dish leans on the elastic force of spring to make universal movement, can guarantee that several to touch plate to cutting knife while and head closely connected.Shortcoming is: install, dismantle inconvenient; Structure is heavy; Be not easy to observe and the adjustment blade; Knife bar is a single point supporting, leans on key to be connected with motor output shaft, because knife bar is longer, can cause the cutting knife dish to get rid of a phenomenon; Moisture and etchant gas are prone to get into bearing, influence the service life of bearing.

Summary of the invention

Goal of the invention: the purpose of the utility model is to solve the problem that existing hot cut pellet machine exists, and provides that a kind of pelletizing is effective, long service life, easy installation and removal, manipulates novel easily hot cut pellet machine.

In order to solve the problems of the technologies described above; The utility model has adopted following technical scheme: a kind of novel hot cut pellet machine, comprise knife bar, and the front end of said knife bar is provided with Cutter apron; Said Cutter apron is connected with cutting knife dribbling type, is provided with the hot cut pellet cover in the outside of Cutter apron and cutting knife dish; Middle part at knife bar is provided with bearing block; Connect through universal joint between the output shaft of the tail end of knife bar and pelletizing motor; Said bearing block and pelletizing motor are fixed on the underframe slide, and the sliding bar of said underframe slide is parallel with knife bar.

Further, the inside of said bearing block is provided with oil sealing and gas check.

Further, said underframe slide is fixed in the unwheeling, and the bottom of a unwheeling is provided with slide rail, and said slide rail is vertical with knife bar.

Further, the outside of said universal joint is provided with protective cover.

Beneficial effect: the cutting knife dish of the utility model is connected with the Cutter apron ball-type, can guarantee several cutting knife simultaneously and head to touch plate closely connected, pelletizing is effective; It is outside that bearing block is located at the hot cut pellet cover, prevents bearing block Yin Gaowen and damage; Establish oil sealing and gas check in the bearing block, can effectively intercept moisture and etchant gas and get into bearing, the service life of further having improved bearing block; Bearing block adopts duplex bearing supported knife bar, has increased the rigidity of knife bar, makes knife bar when rotating, not have jumping phenomena; Connect through universal joint between knife bar and the pelletizing motor, reduced the error requirements of the central point centering of knife bar and pelletizing motor; Bearing block and pelletizing motor are fixed on the underframe slide, can very easily the cutting knife part be shifted out from the hot cut pellet cover, are convenient to the installation and the adjustment of cutting knife; The underframe slide is fixed in the unwheeling, and a unwheeling can be done laterally to slide by slide rail along the below, for the workman overhauls the operating space that provides bigger to equipment.

Description of drawings

Fig. 1 is the main apparent direction structural representation of the utility model.

Fig. 2 is the side-looking direction structure sketch map of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done explanation further.

Of Fig. 1 and 2; A kind of novel hot cut pellet machine of the utility model comprises knife bar 1; The front end of said knife bar 1 connects Cutter apron 2, and said Cutter apron 2 is connected with cutting knife dish 3 ball-types, is provided with hot cut pellet cover 5 in the outside of Cutter apron 2 and cutting knife dish 3; Cutting knife dish 3 leans on the elastic force of Cutter apron 2 upper springs to make universal movement, can guarantee that several to touch plate to cutting knife while and head closely connected.

Be provided with bearing block 4 at the middle part of knife bar 1, bearing block 4 is located at the outside of hot cut pellet cover 5, makes the operating ambient temperature of bearing block 4 remain room temperature, prevents that bearing block 4 from damaging because of high temperature.Establish oil sealing and gas check (but trachea) in the bearing block 4, can effectively intercept moisture and etchant gas and get into bearing, the service life of further having improved bearing block 4.In addition, bearing block 4 adopts duplex bearing supported knife bar 1, has increased the rigidity of knife bar 1, makes knife bar 1 when rotating, not have jumping phenomena.

Connect through universal joint 7 between the output shaft of the tail end of knife bar 1 and pelletizing motor 6, be provided with protective cover 11 in universal joint 7 outsides, universal joint 7 has reduced the error requirements of the central point centering of knife bar 1 and pelletizing motor 6.

Said bearing block 4 is fixed on the underframe slide 8 with pelletizing motor 6; The sliding bar of said underframe slide 8 is parallel with knife bar 1; Bearing block 4 and pelletizing motor 6 can be in axial sliding along sliding bar with underframe slide 8; Can very easily the cutting knife part be shifted out from hot cut pellet cover 5, be convenient to the installation and the adjustment of cutting knife part.

Said underframe slide 8 is fixed in the unwheeling 9, and the bottom of a unwheeling 9 is provided with slide rail 10, and said slide rail 10 is vertical with knife bar 1, and a unwheeling 9 can be done laterally to slide along slide rail, for the workman overhauls the operating space that provides bigger to equipment.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
