Abstract

The utility model discloses a modified structure of a cutter for crushing rubber blocks, which mainly comprise a frame, a main shaft, moving cutter holders, moving cutters and a fixed cutter, wherein the fixed cutter is arranged on the frame with adjustable position, the moving cutters are arranged on the moving cutter holders and provided thereon with key grooves, and are fixed on the main shaft via a flat key. The utility model is characterized in that the plurality of moving cutter holders are fixed on the same main shaft and the positions of the key grooves on the moving cutter holders are different. The smooth connection lines between points at the cutting edge of the moving cutter on the moving cuter holder combine to form a helical curve with a helical angle Beta. The moving cutters and the fixed cutter combine to form a special helical cutting structure with triangular cutting blade. The utility model has the advantages of high cutting efficiency, low energy consumption, efficient protection against damage to the cutter, and long service life of the cutter.

Description

Blob of viscose crushing machine cutting tool structure-improved

Technical field

The utility model relates to a kind of pulverizer, especially a kind of blob of viscose crushing machine cutting tool structure-improved.

Background technology

Along with at home flourish of rubber and plastic industry, traditional pulverizer has obtained using widely in this industry.But still there are many constructional defectives in traditional pulverizer and demand urgently improving in operating efficiency, operating noise, energy consumption and maintaining.

The utility model content

In order to solve the problem that traditional pulverizer exists, the utility model provides a kind of cutter life length, high efficiency, stable performance, blob of viscose crushing machine cutting tool structure-improved that energy consumption is low.

The utility model is implemented by the following technical programs:

Blob of viscose crushing machine cutting tool structure-improved, mainly comprise body, main shaft, moving knife body, moving knife, stationary knife, the stationary knife that the position is adjustable is installed on the body, moving knife is installed on the moving knife body, have keyway on the moving knife body and be connected on the main shaft by flat key, it is characterized in that: have a plurality of moving knife bodies to be connected on the same main shaft, and the keyway position on the moving knife body is inequality.

The moving knife body quantity that is connected on the main shaft is generally odd number, usually it is 0 ° with first set positions with last moving knife body keyway, second position with penult moving knife body keyway is β °, and the 3rd position with third from the bottom moving knife body keyway is 2 β ° ... the rest may be inferred for all the other; Be installed on the moving knife cutting edge same position on the moving knife body arbitrarily a bit between level and smooth line to have formed helical angle be the helix of β, then formed special screw type triangle sword shear constitution between moving knife and the stationary knife.

Described moving knife body along the circumferential direction five equilibrium has a plurality of grooves, and the sidewall of its further groove one side extends a dress knife face.

The moving knife hold-down bolt is housed on the sidewall of the opposite side of described groove.

The blade of described moving knife is the dihedral sword.

The blade of described stationary knife is the dentation sword that cooperates with the dihedral sword of moving knife.

Have six grooves and six dress knife faces on the described moving knife body, have the moving knife positioning screw hole on each dress knife face.

Effect of the present utility model is:

(1) special moving knife body structure makes on each dress knife face that with moving knife set bolt and moving knife hold-down bolt a slice blade that has been connected be the moving knife of dihedral sword, and this moving knife cooperates with the stationary knife of dentation sword again, has improved and has cut efficient, has saved energy consumption.

(2) the moving knife body that moving knife has been installed is connected on the main shaft by the connection rule of flat key, makes moving knife form special screw type triangle sword shear constitution; The driven by motor main shaft runs up, and makes moving knife and stationary knife carry out the straight sword of screw type and shears continuously, has improved operating efficiency greatly, and this cut mode can effectively protect cutter, avoids bigger damage, thereby has prolonged the service life of cutter.

The specific embodiment

Embodiment

Blob of viscose crushing machine cutting tool structure-improved shown in Fig. 1,2,4, mainly comprise body 1, main shaft 2, moving knife body 3, moving knife 4, stationary knife 5, moving knife body 3 along the circumferential direction five equilibrium has six each and every one grooves 8, the sidewall of its further groove 8 one sides extends a dress knife face 9, has moving knife positioning screw hole 16 on each dress knife face; Have screw 10 on the sidewall of the opposite side of groove, be used to install moving knife hold-down bolt 13, keyway 6 positions are inequality, and each moving knife body keyway 6 is connected on the main shaft 2 by flat key 7.

As shown in Figure 5, the blade of moving knife 4 is the dihedral sword, has moving knife locating hole 11 on it, and moving knife 4 is fixed on the moving knife body 3 by moving knife bolt 12.

As shown in Figure 3, the blade of stationary knife 5 is the dentation sword that cooperates with the dihedral sword of moving knife 4, has stationary knife locating hole 14 and stationary knife positioning screw hole 15 on it, and the stationary knife 5 that the position is adjustable is installed on the body 1 by bolt.

As shown in Figure 6, there are a plurality of moving knife bodies 3 to be connected on the same main shaft 2, the quantity of moving knife body 3 is generally odd number, have keyway 6 on the moving knife body 3, usually it is 0 ° with first set positions with last moving knife body keyway, second position with penult moving knife body key 6 is β °, and the 3rd position with third from the bottom moving knife body keyway is 2 β ° ... the rest may be inferred for all the other; Then formed special screw type triangle sword shear constitution between moving knife and the stationary knife; Driven by motor main shaft 2 runs up, and makes moving knife 4 and stationary knife 5 carry out the straight sword of screw type and shears continuously, has improved operating efficiency greatly, and this cut mode can effectively protect cutter, avoids bigger damage, thereby has prolonged the service life of cutter.
