The invention also provides a novel extruder, which can automatically take down the rubber material from the material cylinder and transfer the rubber material into the screw assembly 20 for extrusion, and specifically, the conveying assembly 10 of the extruder is provided with a conveyor belt and a conveying motor, the conveying motor drives the conveyor belt to move so as to drive the rubber material on the conveyor belt to move towards the feeding hopper 21, and the opening at the upper end of the feeding hopper 21 is larger than that at the lower end, so that the rubber material can conveniently enter the feeding hopper 21 and enter the screw assembly 20.

The invention also provides a sizing material processing method to realize automatic feeding of an extruder, which comprises the steps of firstly transferring sizing materials to the conveying component 10, driving a press roller to rotate through a driving motor to clamp the sizing materials to move, so that the sizing materials are pulled out from a winding drum, arranging a metal detector on the conveying component 10 to detect whether the sizing materials on the conveying belt contain metal impurities, if the sizing materials with metal are cut off through a cutting component 40 in an extruder rejecting device, then moving out of the conveying component 10, under the normal condition that the sizing materials do not exist, smoothly transferring the sizing materials from one end of the conveying component 10 to one end close to the feeding hopper 21, continuously moving the end of the sizing materials to fall into the feeding hopper 21, at the moment, detecting the sizing materials in the feeding hopper 21 through a first detecting component 35 of a material guiding component 30, driving a first driving cylinder to move through a controller to drive a rubber inserting head plate to move towards the inner side of the feeding hopper 21, so as to push the rubber material in the feeding hopper 21 to the bottom of the feeding hopper 21, and the screw assembly 20 on the extruder drives the rubber material to enter the extruder for extrusion, thereby automatically completing the whole feeding and quality inspection work.

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.
