Specific embodiment

The utility model provides many applicable creative concepts, which can be reflected in a large number of specifically Context in.The specific embodiment described in following the embodiments of the present invention is only used as the tool of the utility model The exemplary illustration of body embodiment, without constituting the limitation to the scope of the utility model.

The utility model will be further described with specific embodiment with reference to the accompanying drawing.

As shown in FIG. 1, FIG. 1 is a kind of yardage roll brake gears of the grooving machine of preferred embodiment provided by the utility model Right view.The present embodiment is a kind of yardage roll brake gear of grooving machine, and the yardage roll brake gear of the grooving machine includes rack 1, the woven bag yardage roll 2 in the rack 1, the brake ribbon 3 being bonded with the surface of the woven bag yardage roll 2.The braiding Bagging volume 2 is continuously fed to joint-cutting device and cuts, and when joint-cutting device pauses, the brake ribbon 3 provides frictional force, slows down described The inertia of woven bag yardage roll 2.

The rack 1 plays support fixed function, and the rack 1 includes first for fixing the woven bag yardage roll 2 The company of rack 11, the second rack 12 of the fixed brake ribbon 3 and connection first rack 11 and second rack 12 Frame 13 is connect, to guarantee that the yardage roll brake gear of the grooving machine is stablized.

The woven bag yardage roll 2 is the yardage roll that braider braiding is completed, and the center of the woven bag yardage roll 2 is equipped with shaft, The shaft is connect with first rack 11, and the cloth cover of the woven bag yardage roll 2 is continuous through traction roller 4 in the rack 1 The joint-cutting device for importing grooving machine, cutting is woven bag after suturing.

The brake ribbon 3 include be fixed on the fixing end 31 in the rack 1, the mobile terminal 32 equipped with clump weight 321, with And the brake band body 33 between the fixing end 31 and the mobile terminal 32.

One end of the brake ribbon 3 is fixed in the second rack 12 of the rack 1 by the fixing end 31.

The mobile terminal 32 is the other end of the brake ribbon 3, and the mobile terminal 32 is equipped with the clump weight 321, described Clump weight 321 is the weight with constant weight, to increase the frictional force between the brake ribbon 3 and the woven bag yardage roll 2.

It is rotated in the woven bag yardage roll 2, when cloth cover feeding joint-cutting device is cut, the brake band body 33 and the volume The outermost layer yardage roll fitting for knitting bagging volume 2, generates frictional force, slows down inertia.

As shown in Fig. 2, Fig. 2 is the structural schematic diagram of brake band body in the yardage roll brake gear of grooving machine shown in Fig. 1.Institute It states brake band body 33 and is equipped with multiple damping fins 331, play damping action, increase the brake ribbon 3 and the woven bag fabric Frictional force between volume 2.When the woven bag yardage roll 2 just starts to cut, it is relatively large in diameter, inertia is also larger, the brake Big with the contact area of the woven bag yardage roll 2 with 3, more damping fins 331 and the woven bag yardage roll 2 are outermost Cloth face contact, frictional force are bigger；When the woven bag yardage roll 2, which is constantly sent to, to be cut, the diameter of the woven bag yardage roll 2 subtracts Small, inertia reduces, and the contact area of the brake ribbon 3 and the woven bag yardage roll 2 reduces at this time, the less damping fin 331 also slow down the woven bag fabric although frictional force reduces with the outermost cloth face contact of the woven bag yardage roll 2 enough The inertia of volume 2.

Further, in the multiple damping fin 331, the coefficient of friction of the adjacent damping fin 331 is different, coefficient of friction The ratio for referring to the frictional force between two surfaces and acting on the vertical force in surface thereof is related with the roughness on surface, therefore When coefficient of friction difference, the different location that the brake band body 33 is contacted with the woven bag yardage roll 2, frictional force is different, can Effectively enhancing frictional force, certainly, the coefficient of friction of multiple damping fins 331 can also be identical, according to the woven bag yardage roll 2 There is the damping fin 331 of corresponding coefficient of friction with the design of cloth cover boot speed.

Further, the area of multiple damping fins 331 is identical, certainly, in multiple damping fins 331, adjacent institute The area for stating damping fin 331 can also be different；Can also the part damping fin 331 area it is identical；Multiple damping fins 331 can be distributed in a uniformly spaced manner, and different spacing also can be set, area and interval are according to needed for the woven bag yardage roll 2 Frictional force accordingly designed, more flexible, there are various deformations.

Further, the brake band body 33 is one or more layers, and the number of plies of the brake band body 33 can basis Depending on the size of the woven bag yardage roll 2, when the brake band body 33 is one layer, structure is simple；The brake band body 33 When for multilayer, wearability is more preferable.

Further, the brake band body 33 is PVC brake ribbon.The wearability of PVC brake ribbon is higher, utilization rate length, Reduce the number of replacement brake ribbon, and then reduce maintenance cost accordingly, reduces machine stop times.

In the present embodiment, the fixing end 31 is identical as the brake material of band body 33, is integrally formed；At other In embodiment, the fixing end 31 is the tension spring connecting with the brake band body 33, when the diameter of the woven bag yardage roll 2 becomes When change, the tension spring generates different deformation, generates different pulling force, and the position for controlling the clump weight 321 is stablized.

As shown in Figure 1, the woven bag yardage roll 2 is provided by the joint-cutting device of grooving machine when grooving machine normal boot-strap Pulling force, the woven bag yardage roll 2 rotate in the counterclockwise direction, and cloth cover constantly imports the joint-cutting device of grooving machine, the brake ribbon 3 Brake band body 33 be bonded with the outermost cloth cover of the woven bag yardage roll 2, the brake ribbon 3 is by the clump weight 321 The influence of the holding power of gravity, the pulling force of the rack 1 and the woven bag yardage roll 2, the brake ribbon 3 and the braiding Frictional force is generated between bagging volume 2, the frictional force that the brake ribbon 3 is subject to is identical as importing direction, the woven bag yardage roll 2 Frictional force that outermost cloth cover is subject to and importing direction prevent institute on the contrary, frictional force can slow down the inertia of the woven bag yardage roll 2 When stating the joint-cutting device pause of grooving machine, cloth cover accumulation guarantees normal production and the normal boot-strap of cutting machine of woven bag.

The utility model is limited it should be noted that above-described embodiment illustrates rather than the utility model System, and those skilled in the art can be designed alternative embodiment without departing from the scope of the appended claims.In In claim, any reference symbol between parentheses should not be configured to limitations on claims.Word "comprising" Element or step not listed in the claims is not excluded the presence of.
