Abstract

The utility model relates to a cutting blade, which mainly comprises a blade body. The blade body consists of two circular blades, a cutting surface of the first blade and a cutting surface of the second blade are partially coincident to form a cutter edge, the first blade which is in the shape of a special gear can grasp cut conveying belts through sharp teeth, and the cut conveying belts are rolled to a cutting opening to be cut, thereby achieving automatic feeding. Simultaneously, a cutting line of the first blade is changed due to the sharp teeth, and cutting angle is changed, so that steel wires in the conveying belts can be cut more effectively. The cutting blade can cut belts, conveying belts and the like effectively, does not generate any spark during cutting, is quite suitable for special fire ban environments such as mines, and further has the advantages of simple structure, wide cutting service range, large cutting force, convenience in installation and the like.

Description

Cutting blade

Technical field

The utility model relates to a kind of blade, particularly a kind of be applied to industrial, the cutting blade that belt, transport tape use.

Background technology

The general inside of the conveyer belt of existing transmission usefulness all includes steel wire, cut this transport tape and need use emery wheel, because the emery wheel cutting mode will produce Mars after cutting to steel wire, makes the mode of this cutting to use under the situation of some taboo fire.And the emery wheel cutting temperature is higher, and transport tape mainly is to be made by rubber, so cutting the time can make the rubber heating on the cutting mouth, causes cutting efficiency to descend, and discharges some harmful substances simultaneously, the harm health of operators.

Summary of the invention

The purpose of this utility model is to provide a kind of good cutting effect for the deficiency that solves above-mentioned technology, and can not produce Mars, produces the few cutting blade of harmful substance.

In order to achieve the above object, the cutting blade that the utility model is designed, it mainly comprises cutter blade, and cutter blade is all circular blade by two to be formed, and the cut surface of the cut surface of first blade and second blade partially overlaps and forms the cutting knife mouth.Described first blade is blade initiatively, and the profile of first blade is gear type, and the tooth of its gear type is straight-tooth or helical teeth.Circle is tangent or crossing at the bottom of the tooth of the line of cut of described second blade and first blade.Special gear type first blade can be caught the transport tape that is cut by pointed tooth, and be involved in cutting mouth cutting, thereby reaches the function of autofeed.Because pointed tooth causes the variation of the first blade cuts line, cause the variation of cutting angle simultaneously, thus can the interior steel wire of more effective cutting transport tape.

In order to cooperate the special requirement of cutting transport tape, cutter blade at least two group pattern settings, and per two groups of cutter blades are that mirror image is oppositely arranged.Be provided with the slitting groove between two groups of cutter blades of mirror image setting, conveniently withdraw from the transport tape that cuts down.

The resulting cutting blade of the utility model, cooperation by last bottom knife cutting knife face forms the cutting knife mouth, steel wire in transport tape and the transport tape is carried out the operation of similar shearing, can effectively cut belt, transport tape etc., and can not produce any Mars during cutting, extremely be fit to as special taboo fire environments for use such as holes, ore deposit.Have the autofeed function simultaneously, and need not to tell rotation during this cutting blade cutting of using, rotating speed is had no requirement, directly manpower drives and cuts.Characteristics such as this cutting blade also has simple in structure, and the cutting scope of application is wide, and cutting force is big, and is easy for installation.

The specific embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1

As shown in Figure 1 and Figure 2, the cutting blade that present embodiment is described, it mainly comprises cutter blade, and cutter blade is all circular blade by two to be formed, and the cut surface 3 of first blade 2 and the cut surface 3 of second blade 4 partially overlap and form cutting knife mouth 5.Described first blade 2 is blade initiatively, and the profile of first blade 2 is gear type, and the tooth 1 of its gear type is a straight-tooth.Circle 7 is tangent or crossing at the bottom of the line of cut 6 of described second blade 4 and the tooth of first blade 2.

Embodiment 2

As shown in Figure 3, Figure 4, the cutting blade that present embodiment is described, circle 7 intersects at the bottom of the line of cut 6 of second blade 4 and the tooth of first blade 2, and the tooth 1 of first blade, 2 gear types is helical teeth.And this cutting blade contains array two groups of cutter blades 1 is set, and two groups of cutter blades 1 are that mirror image is oppositely arranged.Be provided with slitting groove 8 between two groups of cutter blades 1.

Claims
