[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The object of the present invention is to provide a debris removal device and a debris removal method for a fiber rod cutting machine, which can automatically separate powder and debris and automatically avoid joints, in view of the defects and shortcomings of the prior art.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1As shown, the present invention provides a debris removal device for a fiber rod cutter, comprising a rod joint sensing mechanism, a rod debris removal mechanism and a rod receiving mechanism arranged in sequence along the movement direction of the rods on the cutter 1, the rod joint sensing mechanism comprising an electrically connected sensing sensor and a controller, the sensing sensor can sense the connection 2 of adjacent rods; the rod debris removal mechanism comprises a screen channel 3 arranged obliquely downward, the feed inlet of the screen channel 3 is located below the blanking port of the cutter 1, the screen channel 3 is provided with screen holes for debris to slide down, and the size of the screen holes is smaller than the diameter of the rods; the rod receiving mechanism comprises a movable rod receiving bucket 5 and a first driving mechanism 4 connected to the rod receiving bucket 5, the first driving mechanism 4 is electrically connected to the controller; when the sensing sensor senses the connection 2, the sensing signal is transmitted to the controller, the controller transmits a control signal to the first driving mechanism 4, and the first driving mechanism 4 drives the rod receiving bucket 5 to leave the blanking area of ​​the screen channel 3. Among them, the controller is an existing device in the prior art, as long as it can realize simple control functions, it will not be elaborated here; the sensing method of the induction sensor can be various, such as color or induction patch, etc., as long as it can determine that the connection 2 is coming and is about to be cut, the induction sensor is set on the cutting machine 1 in a fixed position to determine the cutting time from when the connection 2 is sensed until the connection 2 is cut, so that the bar receiving bucket 5 can accurately avoid the dropped joint; the screen channel 3 needs to ensure that the dropped bar accurately enters the bar receiving bucket 5 when it falls, so the screen channel 3 needs to have the characteristic of preventing the uncertainty of the falling trajectory of the bar, such as setting the screen channel 3 to annular channel, or increase the receiving area of ​​the screen channel 3, the screen channel 3 can be a rectangular structure as shown in the figure, or a cylindrical structure, or other structures, but the receiving surface of the rectangular structure is a plane, so it is more conducive to the rod material to bounce and roll and fall, and it is conducive to the debris falling from the rod material; the mobility of the rod receiving bucket 5 can be possessed by itself, or it can be placed on other structures with mobile functions. At the same time, the rod receiving bucket 5 can be detachable or non-detachable, but in order to facilitate work, the rod receiving bucket 5 needs to have a detachable function; the first driving mechanism 4 is a screw structure or a telescopic cylinder or other structures with reciprocating motion;

[0030] In summary, the present invention adopts a bar joint sensing mechanism, a bar debris removing mechanism and a bar receiving mechanism which are sequentially arranged along the moving direction of the bar on the cutting machine 1. Through the screen channel 3 with screen holes arranged obliquely in the bar debris removing mechanism, and through the tumbling action of the fiber rod in the screen channel 3, the debris of the cut fiber rod is removed; further, the connection 2 of adjacent bars is sensed by the inductive sensor in the bar joint sensing mechanism, and when the inductive sensor senses the connection 2, the inductive signal is transmitted to the controller, and the controller transmits a control signal to the first driving mechanism 4, and the first driving mechanism 4 drives the bar receiving bucket 5 to leave the falling area of ​​the screen channel 3, thereby completing the work of avoiding the falling joint.

[0031] In order to ensure the bouncing and rolling effects of the rods during the falling process, the screen channel 3 in the present invention is a metal screen with elastic properties, so that the rods can fall better with the assistance of the screen, thereby improving the debris removal effect.

[0032] As a preferred embodiment, the inclination angle of the screen channel 3 in the present invention is adjustable, and the inclination angle is 60°. Of course, it can also float around this angle, for example, 45 degrees to 70 degrees; when the screen channel 3 is a rectangular structure as shown in the figure, when the inclination angle is 60°, the rod material can bounce on the bottom surface of the screen channel 3, and can also bounce on the top surface of the screen channel 3, further improving the debris removal effect.

[0033] In order to ensure the chip removal stroke of the bar material, the inclined length of the screen channel 3 in the present invention is 10 to 40 cm.

[0034] In order to facilitate the collection of debris, a debris receiving portion is arranged below the screen channel 3 in the present invention.

[0035] As a preferred embodiment, the sensing sensor in the present invention is a color sensing sensor 6, and a sensitive colored portion is provided at the connection 2 of adjacent bars. For example, the adjacent bars are bonded with yellow tape. When the color sensing sensor 6 senses yellow, the connection 2 of the adjacent bars is cut within a certain period of time, the joint falls off, and the joint needs to be avoided.

[0036] In order to ensure the consistency of coordination between the bar receiving mechanism and the cutting machine 1, the sensing sensor in the present invention also includes a speed sensor 7, which can sense the moving speed of the bar. The speed sensor 7 is electrically connected to the controller so that when the movement speed of the bar does not meet the corresponding requirements, an alarm is sounded through the alarm device; or when the cutting machine 1 is started but the bar does not move, if the bar receiving mechanism moves, the avoidance action of the bar receiving mechanism will not have the corresponding effect, and the bar receiving mechanism will not perform the avoidance action.

[0037] As a preferred embodiment, the bar receiving mechanism in the present invention includes a movable base, the bar receiving bucket 5 is arranged on the base, the base is connected to the first driving mechanism 4, and the base is provided with moving wheels or slide rails.

[0038] In order to facilitate the collection of joints, the rod receiving mechanism in the present invention also includes a movable joint receiving bucket 8, which is linked to the rod receiving bucket 5, or the joint receiving bucket 8 is connected to the corresponding second driving mechanism, and the second driving mechanism is electrically connected to the controller; when the first driving mechanism 4 drives the rod receiving bucket 5 to leave the falling area of ​​the screen channel 3, the joint receiving bucket 8 enters the falling area of ​​the screen channel 3, so that the fallen joints can be collected in time, avoiding the problem of secondary collection after the joints fall.

[0039] The present invention also provides a method for removing fiber rod debris in a fiber rod cutting machine, comprising the following contents:

[0040] Send the fiber material rod to the cutting machine 1, and adjust the cutting speed of the cutting machine 1;

[0041] The cut fiber rods fall into the inclined screen channel 3, where they bounce and roll, and during the falling process, the debris falls through the screen holes to the outside of the screen channel 3, and the fiber rods fall into the rod receiving bucket 5;

[0042] When the induction sensor senses the connection 2, the induction signal is transmitted to the controller, and the controller transmits a control signal to the first drive mechanism 4. The first drive mechanism 4 drives the rod receiving bucket 5 to separate from the blanking area of ​​the screen channel 3; at the same time, the joint receiving bucket 8 is linked with the rod receiving bucket 5 to enter the blanking area of ​​the screen channel 3.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
