Specific embodiment

Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating The utility model and be not limited to limitation the scope of the utility model.Implementation condition used in the examples can be according to specific producer Condition do further adjustment, the implementation condition being not specified is usually the condition in routine experiment.

It referring to fig. 2-6, is the structural schematic diagram of the utility model embodiment, the utility model embodiment provides one kind and cuts Device is applied to tyre building machine, for cutting tire composite layer.Tyre building machine include tire body feeding frame (not shown) and It is installed at least two conveying templates 2 on tire body feeding frame and for conveying tire composite layer.Wherein, cutting means are fixed on On tire body feeding frame, two conveying templates 2 are arranged at tire composite layer conveying direction interval.

Specifically, cutting means include that cutting component 1, being arranged in two conveying templates 2 for 2 top of conveying templates is arranged in Between cut-out plate 3, the press component 4 being arranged on conveying templates 2 and the air blowing component 5 being arranged in cut-out plate 3.Work as wheel Tire composite layer has been fed forward certain length, and press component 4 pushes down tire composite layer, and cut component 1 can be to taking turns in cut-out plate 3 Tire composite layer is cut.After the completion of tire composite layer is cut, a part of tire composite layer can be pasted onto cut-out plate 3, be blown Pneumatic module 5 can blow to the tire composite layer being pasted in cut-out plate 3, and tire composite layer is made to be detached from cut-out plate 3, thus convenient Tire composite layer after cutting be delivered to it is next need position, and not will cause the bending or deformation of tire composite layer.

Component 1 is cut to include the bracket 1-1 arranged along the direction vertical with conveying direction, be slidably arranged on bracket 1-1 Cut-off knife component 1-2 and the driving assembly 1-3 that is slided along bracket 1-1 of driving cut-off knife component 1-2.Bracket 1-1 is equipped with guide rail 1-1a, cut-off knife component 1-2 are slidably matched with guide rail 1-1a.Driving assembly 1-3 includes the motor 1- that the one end bracket 1-1 is arranged in 3a, the synchronizing wheel 1-3b that the bracket 1-1 other end is set and the ring-shaped synchronous belt 1- for connecting motor 1-3a and synchronizing wheel 1-3b 3c, cut-off knife component 1-2 are connected to the side ring-shaped synchronous belt 1-3c.Above-mentioned bracket 1-1 is fixed on tire body feeding frame.

Cut-off knife component 1-2 includes knife rest 1-2a and the pressing roller 1-2b and cut-off knife 1-2c that are arranged on knife rest 1-2a, knife rest The rear end of 1-2a is slidably matched with guide rail 1-1a, and the top of knife rest 1-2a is fixed on the side ring-shaped synchronous belt 1-3c by fixture block, Pressing roller 1-2b and cut-off knife 1-2c is along direction and row interval setting is cut, and wherein cut-off knife 1-2c uses ultrasonic cutter.When cutting, Pressing roller 1-2b first carries out roll-in to tire composite layer, one end of tire composite layer is located in cut-out plate 3, then cut-off knife 1-2c cuts tire composite layer.

The side for cutting component 1 is arranged in along conveying direction for press component 4.Press component 4 includes being arranged in conveying templates 2 The pressing plate 4-3 of top, two support frame 4-2 for being connected to the two sides pressing plate 4-3 and be located at 2 two sides of conveying templates and difference Connect two driving cylinder 4-1 of support frame 4-2.Wherein, support frame 4-2 is pivotally connected to tire body feeding frame, due to support frame 4-2 is connect with pressing plate 4-3, and driving cylinder 4-1 also connects support frame 4-2, therefore, by driving cylinder 4-1 that can drive pressing Plate 4-3 is rotated and is pressed on conveying templates 2.The equivalent width of the width of pressing plate 4-3 and tire composite layer, when cutting group When part 1 cuts tire composite layer, driving cylinder 4-1 driving pressing plate 4-3, which is pressed, to be pressed on tire composite layer, is then cut out It cuts component 1 to be cut, by the effect of pressing plate 4-3, tire composite layer is mobile when avoiding cutting, and guarantees to cut out smooth cut.

Air blowing component 5 includes that the first tracheae 5-1 below cut-out plate 3 is arranged in and is arranged in more on the first tracheae 5-1 A second tracheae 5-2.Wherein the first tracheae 5-1 is connected to gas source, and second one end tracheae 5-2 is connected to the first tracheae 5-1, the The two tracheae 5-2 other ends are connected to the gas hole 3-1 being arranged in cut-out plate 3.

When cutting, after pressing roller 1-2b presses tire composite layer, the liner of tire composite layer and sidewall can all be pasted onto sanction On cutting plate 3, paste wherein being located in the middle liner than more serious.Therefore, in this example, the gas hole 3-1 in cut-out plate 3 is in centre More, both ends are arranged less, to ensure that liner can completely disengage cut-out plate 3 after blowing.

Specifically, the middle part of cut-out plate 3 is equipped with spaced apart several gas hole groups, each gas hole group includes multiple rows of the One gas hole 3-1a.It is equipped in cut-out plate 3 and is connected to each air blowing road that ranked first gas hole 3-1a, be located at 3 middle part of cut-out plate The gas outlet of the second tracheae 5-2 be connected to air blowing road, by the second tracheae 5-2 toward it is each ranked first gas hole 3-1a blow with Liner is set to be detached from cut-out plate 3, wherein air blowing road is fabrication hole used in production, and fabrication hole is arranged to ensure often to ranked first air blowing Hole 3-1a is connected with fabrication hole, and when use need to block the open end of fabrication hole.The both ends of cut-out plate 3 are respectively equipped with several Second gas hole 3-1b, the gas outlet of the second tracheae 5-2 at 3 both ends of cut-out plate is connected individually to the second gas hole 3-1b, several The position of a second gas hole 3-1b can arrange as needed, and the utility model is with no restrictions.

It is equipped in cut-out plate 3 and cuts slot 3-2, this cuts slot 3-2 and arranges along the length direction of cut-out plate 3, when cutting, cuts out The point of a knife of knife 1-2c is cut along cutting slot 3-2 and move completion from one end to the other end.

In conclusion since air blowing component 5, after the completion of tire composite layer is cut, air blowing component being arranged in cut-out plate 3 5 blow to tire composite layer, so that tire composite layer is detached from cut-out plate 3, avoid after the completion of cutting, cut-out plate 3 is in transmission process Tire composite layer formation pull and damage, guarantee the quality of the tire cladding after fixed length is cut.

Examples detailed above is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with technique People is can to understand the content of the utility model and implement accordingly, is not limited the protection scope of the present invention.It is all According to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it It is interior.
