Description

The structure-improved of volute casing threading tool Crusher Room

Technical field:

The utility model relates to the volute casing structure of Material disintegrator, refers in particular to the structure-improved of a kind of volute casing threading tool Crusher Room.

Background technology:

At present, China's plastics disintegrating apparatus has two kinds of main products, the one, traditional, its primary structure is that the front and rear wall of Crusher Room respectively is equipped with the cutter that is ranked, flat cutter or how tangent pawl cutter and stationary knife is installed on the movable arbor, because the rotary cutter on the cutter shaft and the tangent number of times of stationary knife are few, pulverizing speed is slow.The 2nd, the equipment that the eighties is introduced from Taiwan, its primary structure is that two cuttves that are ranked respectively are installed on the front and back walls of Crusher Room, be fixed with flat cutter or how tangent on the movable arbor pawl cutter and stationary knife, though this equipment has improved crush efficiency, but have following several problem equally: 1, the particle in the Crusher Room splashes seriously, the accident of hurting sb.'s feelings often occurs; 2, light plastic is not easy to enter Crusher Room, as mineral water bottle; 3, pulverize bigbore plastics difficulty (as bigbore PE tubing), even can show the movable arbor stuck phenomenon; 4, crushing process is with painful noise.

The utility model content:

The purpose of this utility model is exactly the weak point that exists at prior art and the structure-improved of a kind of volute casing threading tool Crusher Room is provided.

To achieve these goals, the technical solution adopted in the utility model is: it comprises volute casing, be provided with cutter shaft in the volute casing, cutter shaft surface along the circumferential direction average mark is furnished with at least four row's cutters, same row's cutter is made up of threading tool and pawl cutter, in two adjacent row's cutters, threading tool and pawl cutter are diagonal setting; Volute casing inside is provided with three cuttves that are ranked, and three the be ranked cutting edges of the cutting edge of cutter and four row's cutters on the cutter shaft are tangent, and three cuttves that are ranked are that circumferencial direction along cutter shaft is provided with, and stationary knife is mounted on the front and back walls of volute casing; The volute casing inner back wall forms the arc stiffener, and at least one row's threading tool is installed on the arc stiffener, and the cutting edge and the cutting edge roundness on the cutter shaft of this threading tool are tangent.

Threading tool on the described cutter shaft is made of the blade at least one tool rest.

Pawl cutter on the described cutter shaft is made of at least one tool rest and the cutting blade that is installed on the tool rest.

Three row's threading tools are installed on the described arc stiffener, and three row's threading tools are the circumferencial direction ladder settings along cutter shaft.

Above the cutter shaft midplane, be provided with an arc striker plate.

After adopting said structure, after waste or used plastics enters volute casing, before this through the threading tool of moulding on the arc stiffener and four shearings of arranging cutters on the cutter shaft, because threading tool on the cutter shaft and pawl cutter are mutual dislocation, can reduce the impulsive force of heavy caliber pipe to cutter shaft, can easily plastics be torn or shear frustillatum, the plastics of little bulk can be shredded by three cuttves that are ranked easily along with rotary cutter rotates, so the utility model can be pulverized the bigger waste or used plastics of volume, and pulverizing speed is fast, also greatly reduces noise simultaneously.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a cutter shaft perspective view of the present utility model.

The specific embodiment:

See that shown in Fig. 1,2, the utility model comprises volute casing 1, is provided with cutter shaft 2 in the volute casing 1, cutter shaft surface along the circumferential direction average mark is furnished with four row's cutters, same row's cutter is made up of threading tool 3 and pawl cutter 4, and in two adjacent row's cutters, threading tool 3 and pawl cutter 4 are diagonal setting; It is tangent that volute casing 4 inside are provided with three the be ranked cutting edges of four row's cutters on the cutting edge of cutter 5 and the cutter shaft 2 of cutter 5, three that are ranked, and three cuttves 5 that are ranked are that circumferencial direction along cutter shaft 2 is provided with, and stationary knife 5 is mounted on the antetheca of volute casing 1; Volute casing 1 inner back wall forms arc stiffener 6, and at least one row's threading tool 7 is installed on the arc stiffener 6, and the cutting edge of the row of four on the cutting edge of this threading tool 7 and the cutter shaft 2 cutter is tangent.

Threading tool 3 on the described cutter shaft 2 is made of the blade 91 at least one tool rest 9.

Pawl cutter 4 on the described cutter shaft 2 is made of at least one tool rest 9 and the cutting blade 41 that is installed on the tool rest 9.

Three row's threading tools 7, three row threading tools 7 be installed be circumferencial direction ladder setting on the described arc stiffener 6 along cutter shaft 2.

Above cutter shaft 2 midplanes, be provided with an arc striker plate 8, arc striker plate 8 can be introduced the waste or used plastics that enters in the volute casing 1 in the rear chamber of volute casing 1 by force, promptly be provided with that side of arc stiffener 6, make waste or used plastics at first be torn, shear for the stationary knife 5 of back and facilitate by the rotary cutter on threading tool on the arc stiffener 67 and the cutter shaft 2.

After waste or used plastics enters volute casing 1, before this through the threading tool 7 of moulding on the arc stiffener 6 and four shearings of arranging cutters on the cutter shaft 2, because in two adjacent row's cutters, threading tool 3 and pawl cutter 4 are diagonal setting, can reduce the impulsive force of heavy caliber pipe to cutter shaft 2, can easily plastics be torn or shear frustillatum, the plastics of little bulk can be shredded by three cuttves 5 that are ranked easily along with rotary cutter rotates.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
