The material guiding assembly 10 is driven by a guiding and opening angle rotation driving device 23, rotates along the cutting rotation central shaft 21, and is guided and opened at an angle alpha with the cutting assembly, so that the calendered cord fabric is guided and opened at an angle alpha with the cutting line through the material guiding assembly 10. The material pulling assembly 110 pulls the material along the alpha direction, and the material pulling assembly 110 is driven by a double-shaft servo to realize the alpha-angle material pulling. The cutting assembly cuts the cord fabric with an angle of alpha degrees. The second conveying mechanism 40 conveys the cord cut to alpha degrees to the splicing position of the crimping assembly 50 and enables the stub bar to be accurately stopped at the splicing position. The crimping unit 50 is driven by the joint angle rotation driving device 24 and rotated along the joint rotation center axis 22 so that the crimping unit 50 forms an angle α with the cutting line. The second transfer mechanism 40 includes a feeding conveyor belt composed of a plurality of strip-shaped expansion belts. The strip-shaped telescopic belt is connected with the rotating beam of the crimping assembly 50 through a guide rail sliding block. The strip-shaped telescopic belt synchronously extends and retracts along with the rotation of the rotating beam. The feeding conveyer belt can stretch according to the cord fabric cutting angle alpha, so that the bevel edge of the cord fabric stub bar can be close to the joint at the minimum distance. Similarly, the first conveying mechanism 30 conveys the cord fabric with the joint angle of α degrees out of the joint position of the crimping assembly 50, and the tail is stopped at the joint position accurately. The first transfer mechanism 30 is composed of a plurality of strip-shaped stretchable belts. The strip-shaped telescopic belt is connected with the rotating beam of the crimping assembly 50 through a guide rail sliding block. The strip-shaped telescopic belt synchronously extends and retracts along with the rotation of the rotating beam. The first conveying mechanism 30 can be extended and retracted according to the cord fabric cutting angle alpha, so that the cord fabric is close to the joint with the minimum distance of the trailing bevel edge. The material head and the material tail of the cord fabric with the alpha degree are lapped through the material pressing component. The continuous cord fabric strip is adhered to the adhesive tape adhering component 130 and finally wound to a reel by the material collecting component 120. The cutting joint process requirement of small angle alpha degree is realized.

The invention has the outstanding characteristic that the automatic cutting joint of the fiber cord fabric with small angle is realized by adopting the structure that the feeding conveyer belt and the discharging conveyer belt stretch together along with the rotation of the joint device. The joint quality is improved, the labor intensity is reduced, and the automation of product production is realized.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
