The stock cutter comprises a rack, a feeding mechanism, a traction mechanism, a cutting mechanism and a motor; the rack is provided with a first bearing base and a second bearing base, which are coaxially arranged; the feeding mechanism comprises a feeding hopper and a guide roller arranged at a feeding opening of the feeding hopper; a plurality of material guide grooves are arranged in the guide roller; the traction mechanism comprises a traction roller and a pressing roller, which are arranged in parallel; the traction roller is mounted on the first bearing base through a bearing; a first gear is mounted at one end of the traction roller; the pressing roller is hinged on the rack; the cutting mechanism comprises a cutter core shaft mounted on the second bearing base through a bearing and a blade mounted on the cutter core shaft; one end of the cutter core shaft is mounted on a second gear which is in engagement transmission with the first gear; and an output shaft of the motor is connected with the cutter core shaft through a belt and a belt wheel, and drives the cutter core shaft to rotate. The stock cutter provided by the utility model has the advantages of simple structure and convenience in operation.

Description

A kind of stock-cutter

(1) technical field

The utility model relates to a kind of for the stock-cutter with the moulding of strip plastic pelletizing.

(2) background technology

After plastic raw materials is extruded by extrusion equipment into strips, for ease of transportation with produce, need to be with its granulation so that transportation and producing.

(3) summary of the invention

The purpose of this utility model is exactly in order to design a kind of plastics stock-cutter with the moulding of strip plastic pelletizing.

For this reason, the utility model adopts following scheme to achieve the above object:

A kind of stock-cutter comprises frame, feeding mechanism, trailer coupling, material cutting mechanism and motor, it is characterized in that: described frame has clutch shaft bearing seat and second bearing seat of coaxial setting; Described feeding mechanism comprises feeder hopper and is arranged on the guiding roller at the feeding mouth place of feeder hopper, on the guiding roller some material guide channels is set; Trailer coupling comprises nip rolls and the hold-down roller that be arranged in parallel, and described nip rolls are installed on the clutch shaft bearing seat by bearing, and an end of nip rolls is equipped with the first gear, and described hold-down roller is hinged on the frame; Material cutting mechanism comprises by bearing and is installed in the cutting knife mandrel on the second bearing seat and is installed in blade on the cutting knife mandrel, and cutting knife mandrel one end is equipped with the second gear and described the first meshed transmission gear; The output shaft of motor is connected with the cutting knife mandrel with belt wheel by belt and drives the cutting knife mandrel and rotates.

Above-mentioned a kind of stock-cutter is characterized in that: described hold-down roller is comprised of pressure roller mandrel and the rubber coating that is sleeved on the pressure roller mandrel.

Above-mentioned a kind of stock-cutter is characterized in that: described nip rolls surface is provided with and convexes to form friction face.

The utility model has the advantage of: simple in structure, easy to operate.

(4) description of drawings

Semi-section schematic diagram when Fig. 1 is mode of operation of the present utility model.

(5) specific embodiment

A kind of stock-cutter as shown in Figure 1 comprises frame 1, feeding mechanism 2, trailer coupling 3, material cutting mechanism 4 and motor.

Frame 1 has clutch shaft bearing seat and second bearing seat of coaxial setting.

Feeding mechanism 2 comprises feeder hopper 21 and is arranged on the guiding roller 22 at the feeding mouth place of feeder hopper 21, on the guiding roller 22 some material guide channels is set.

Trailer coupling 3 comprises nip rolls 31 and the hold-down roller 32 that be arranged in parallel.Nip rolls 31 are installed on the clutch shaft bearing seat by bearing, and an end of nip rolls 31 is equipped with the first gear, and nip rolls 31 surfaces are provided with and convex to form friction face.Described hold-down roller 32 is hinged on the frame 1, and hold-down roller 32 is comprised of pressure roller mandrel and the rubber coating that is sleeved on the pressure roller mandrel.

Material cutting mechanism 4 comprises by bearing and is installed in the cutting knife mandrel 41 on the second bearing seat and is installed in blade 42 on the cutting knife mandrel 41, and cutting knife mandrel 41 1 ends are equipped with the second gear and described the first meshed transmission gear.

The output shaft of motor is connected with cutting knife mandrel 41 with belt wheel by belt and drives cutting knife mandrel 41 and rotates.

During work, first strip-shaped materials 5 is put in the close clearance that forms between nip rolls 31 and the hold-down roller 32, start motor, cutting knife mandrel 41 rotates material cutting mechanism 4 and begins action, thereby in the rotation of cutting knife mandrel 41, be installed in one end the second gear and the first meshed transmission gear and realize that nip rolls 31 rotate, strip-shaped materials 5 is pulled roller 31 with the hold-down roller 32 extruding little distortion of generation and at the uniform velocity is fed forward under the friction force combined action of its generation delivers to material cutting mechanism 4, forms particle under the effect of blade 42.

Nip rolls 31 surfaces are provided with and convex to form friction face and obtain larger friction force by strip-shaped materials 5 and be fed forward.Rubber coating can push strip-shaped materials 5 on the hold-down roller 32, not only makes stock-cutter be adapted to strip-shaped materials 5 processing of various different-thickness, and makes strip-shaped materials 5 obtain larger friction force to be fed forward, to work more steady, and noise is little.

Be necessary to be pointed out that at this above embodiment only is used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the those of ordinary skill in this field can be made some nonessential improvement and adjustment to above embodiment according to essence of the present utility model.
