[0020] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0023] To solve the problem of poor cord fabric cutting effect in the prior art, the present application provides a cord fabric cutting and conveying device.

[0024] As Figure 1 shown, the cord fabric cutting and conveying device in the present application includes a conveyor belt 10, a rotating frame 20, a cutting knife assembly 30, a cutting knife backing plate 40, and a pressing rod assembly 50. The conveyor belt 10 is used to convey the cord fabric; at least a part of the rotating frame 20 is arranged above the conveyor belt 10; the cutting knife assembly 30 is arranged on the rotating frame 20 and can move along the rotating frame 20, and the rotating frame 20 can drive the cutting knife assembly 30 to rotate relative to the conveyor belt 10 to change the included angle between the cutting path of the cutting knife assembly 30 and the moving direction of the conveyor belt 10; the cutting knife backing plate 40 is arranged on the rotating frame 20, and the cutting knife backing plate 40 is arranged between the cutting knife assembly 30 and the conveyor belt 10 so that the cord fabric on the conveyor belt 10 can move between the cutting knife backing plate 40 and the cutting knife assembly 30; the pressing rod assembly 50 is arranged on the rotating frame 20 and is located between the cutting knife assembly 30 and the cutting knife backing plate 40, and the pressing rod assembly 50 can move in a direction close to or away from the cutting knife backing plate 40. When the cutting knife assembly 30 cuts the cord fabric, the pressing rod assembly 50 moves towards the cutting knife backing plate 40 and presses the cord fabric against the cutting knife backing plate 40, and at least a part of the cutting knife assembly 30 can pass through the pressing rod assembly 50.

[0025] When using the cord fabric cutting and conveying device in the present application, due to the presence of the conveyor belt 10, the cord fabric to be cut can be cut through the conveyor belt 10, and since the cutting knife assembly 30 is arranged on the rotating frame 20, the rotating frame 20 can drive the cutting knife assembly 30 to rotate relative to the conveyor belt 10, thereby changing the cutting angle of the cutting knife assembly 30 for the cord fabric to be cut. At the same time, when the cutting knife assembly 30 cuts the cord fabric, during the process of the conveyor belt 10 conveying the cord fabric, the cord fabric can pass above the cutting knife backing plate 40, and the cord fabric located above the cutting knife backing plate 40 can be pressed by the pressing rod assembly 50, so that the cutting knife assembly 30 can cut the cord fabric after passing through the pressing rod assembly 50. Therefore, by arranging the pressing rod assembly 50, it is possible to prevent the cut cord fabric from adhering to the cutting knife assembly 30, and by pressing the cord fabric by the pressing rod assembly 50 and the cutting knife backing plate 40, it is possible to prevent the cord fabric from skewing during the cutting process. Therefore, the cord fabric cutting and conveying device in the present application effectively solves the problem of poor cord fabric cutting effect in the prior art.

[0026] It should be noted that the cord fabric cutting and conveying device in this application is mainly aimed at the cutting and conveying of large-angle ultra-thin and ultra-short fiber cord fabrics. And here, the large angle generally refers to the angle between the cord and the conveying direction of the conveyor belt 10, and the difference between the maximum and minimum values of the angle range is 30 degrees. Of course, the cord fabric cutting and conveying device in this application can also be used in other angle ranges. Ultra-thin generally refers to a fiber cord fabric with a thickness of 0.5 mm, and ultra-short generally refers to a cord fabric with a minimum length of 200 mm.

[0027] Specifically, a cutting groove is provided on the cutting blade backing plate 40 corresponding to the cutting path of the cutting blade assembly 30, and a positioning opening is provided on the pressing rod assembly 50 corresponding to the cutting groove. At least a part of the cutting blade assembly 30 can pass through the positioning opening to extend into the cutting groove and move along the cutting groove. That is to say, when the cutting blade assembly 30 cuts the cord fabric, the cutting blade assembly 30 can cooperate with the cutting groove, so as to be able to cut along the cutting groove. Such a setting can effectively ensure that the cutting blade assembly 30 can cut the cord.

[0028] Specifically, the side wall of the cutting blade backing plate 40 facing the cord fabric has a plurality of air holes, and when the cord fabric moves to the cutting blade backing plate 40, the air holes blow air towards the cord fabric.

[0029] In a specific embodiment of this application, the side wall of the cutting blade backing plate 40 with air holes is an inclined surface and is inclined along the movement direction of the cord fabric. The plurality of air holes are divided into two groups. The blowing direction of one group of air holes is parallel to the movement direction of the conveyor belt 10, and the blowing direction of the other group of air holes is perpendicular to the side wall. And the cross-section of the cutting blade backing plate 40 is trapezoidal. That is to say, in this application, the extending direction of the cutting groove is the length direction of the cutting blade backing plate 40, and the cross-section of the cutting blade backing plate 40 in the width direction is trapezoidal, preferably an isosceles trapezoid. One of the two side edges of the trapezoid is at the upstream position when the conveyor belt 10 moves forward, and the other side edge is at the downstream position when the conveyor belt 10 moves forward. The side edge at the upstream position is the side wall facing the cord fabric, and the plurality of air holes are distributed along the length direction of the cutting blade backing plate 40. In this way, when the cord fabric moves near the cutting blade backing plate 40, the cord fabric can move above the cutting blade backing plate under the blowing action of the air holes, and after the cutting assembly completes the cutting of the cord fabric, the blowing action of the air holes can prevent the cord fabric from adhering to the cutting blade backing plate 40.

[0030] And it should be noted that the inside of the cutting blade backing plate 40 has an air cavity communicated with the air holes, and the cord fabric cutting and conveying device also has a blowing device, and the blowing device is communicated with the air cavity and blows air into the air cavity.

[0031] It should also be noted that when the cord fabric needs to be cut, the pressing rod assembly 50 moves in the direction close to the cutting tool backing plate 40 to clamp the cord fabric. After the cord fabric is cut, the pressing rod assembly 50 moves in the direction away from the cutting tool backing plate 40 and separates from the cutting tool backing plate 40 to facilitate the smooth conveyance of the cord fabric by the conveyor belt 10.

[0032] Meanwhile, in this application, when the cord fabric is conveyed and cut, the conveyor belt 10 first moves forward to enable the cord fabric to move above the cutting tool backing plate 40. After the cord fabric is cut, the conveyor belt 10 first moves backward a certain distance and then moves forward a certain distance. The purpose of this setting is to ensure that the rubber material can be completely separated.

[0033] Specifically, the cutting tool assembly 30 includes a first driving structure 31, a left cutting tool 32, and a right cutting tool 33. The first driving structure 31 is arranged on the rotating frame body 20; a slide rail is arranged on the rotating frame body 20. The first driving structure 31 is respectively drivingly connected to the left cutting tool 32 and the right cutting tool 33 so that the left cutting tool 32 and the right cutting tool 33 can respectively move along the slide rail, and the moving directions of the left cutting tool 32 and the right cutting tool 33 are opposite. In an alternative embodiment of this application, the first driving structure has a synchronous belt, and the left cutting tool and the right cutting tool are respectively arranged in two running directions of the synchronous belt, and the left cutting tool and the right cutting tool are respectively arranged on the slide rail through sliders, so as to ensure that the left cutting tool and the right cutting tool can move along the slide rail and the moving directions are opposite. Of course, in this application, the first driving structure may also include a plurality of driving motors, and driving motors are respectively arranged on the left cutting tool and the right cutting tool, so that the left cutting tool and the right cutting tool can move along the slide rail. In addition, the first driving structure may also be a telescopic rod structure, and both ends of the telescopic rod can be telescoped. The left cutting tool and the right cutting tool are respectively arranged at both ends of the telescopic rod structure to be able to move along the slide rail. Therefore, in this application, the first driving structure only needs to ensure that the left cutting tool and the right cutting tool can move along the slide rail and the moving directions are opposite to smoothly complete the cutting of the cord fabric.

[0034] Optionally, the pressing rod assembly 50 includes a pressing rod body and a second driving structure. The pressing rod body has a positioning opening; the second driving structure is arranged on the rotating frame body 20 and is drivingly connected to the pressing rod body so that the pressing rod body can move in the direction close to or away from the cutting tool backing plate 40.

[0035] Specifically, the cord fabric cutting and conveying device further includes a bracket 60 and a pressure roller assembly 70. The rotating frame body 20 is arranged on the bracket 60; the pressure roller assembly 70 is arranged on the bracket 60, and the pressure roller assembly 70 is located downstream of the conveyor belt 10 relative to the cutting tool backing plate 40. The pressure roller assembly 70 is located above the conveyor belt 10 and can move in a direction close to or away from the conveyor belt 10. Preferably, the pressure rod assembly 50 moves synchronously with the pressure roller assembly 70. That is to say, when cutting the cord fabric, the cord fabric located on the cutting tool backing plate 40 can be pressed by the pressure rod assembly 50, and the cord fabric at the downstream position of the cutting tool backing plate 40 can be pressed by the pressure roller assembly 70.

[0036] Optionally, the surface of the cutting tool backing plate 40 has a Teflon coating. By setting it like this, it can effectively ensure that the rubber material adheres to the cutting tool backing plate 40.
