Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a carding machine with a fiber feeding quantity self-regulating function.
Background
Carding machines, also known as carding machines, are an important part of the production facility of a complete set of nonwoven products. As is known in the art, a complete nonwoven product such as a nonwoven fabric or nonwoven felt production line mainly comprises a bale opener, an opener, a hopper, a carding machine, a lapping machine and a needle machine (a hydroentangler may also be used), the carding machine functions to comb the nonwoven fibers opened by the opener of the preceding station, after which the nonwoven fibers are laid up to a nonwoven web of the desired grammage by being fed to the subsequent lapping machine by a fiber output mechanism belonging to the structural system of the carding machine, and then to the aforementioned needle machine or hydroentangler for needling or hydroentangling.
Technical information about carding machines belonging to the category of nonwoven machines, such as CN206089904U (carding machine) and CN202466005U (nonwoven carding machine), etc., is very much seen in the published chinese patent literature. More representative are "nonwoven cards" as recommended by CN206109623U and "pure cotton roller cards" as provided by CN113046866 a.
As is also known in the art, during the feeding of nonwoven fibers into the main body of the carding machine by the curtain of the card architecture, there is always the problem of unavoidable variation in the amount of cotton fed, i.e. the amount of fiber fed, which means that the nonwoven fibers fed by the curtain are inadvertently too much and too little, and consequently the amount of nonwoven fibers carded by the main body is also uneven, with the result that the nonwoven web layer laid by the subsequent fleece layer is not uniform in terms of gram weight, ultimately affecting the quality (non-uniform gram weight) of the nonwoven product produced by the needle-punching machine or the hydroentangling machine. It has been found that the quality of the final nonwoven product meets the desired requirements only by eliminating as much as possible the problem of uneven cotton feed to the feed curtain.
Technical information on carding machines relating to the autoleveling function is seen in the published chinese patent literature, typical of "an autoleveling feed mechanism of a carding machine" as recommended by CN206828701U and CN210262115U are provided with "an autoleveling carding device". Both of the foregoing patents suffer from the general disadvantage of addressing the symptoms rather than the root cause of the failure because the thickness tends to be uniform by the reasonable application of pressure to the nonwoven fibrous cotton layer fed by the feed curtain and the uniformity of the amount of fibers fed cannot be achieved by incremental or decremental means to the fibers, so that the inconsistent factors of grammage of the final nonwoven product are not sufficiently eliminated.

The applicant has not described in detail the card body 1, since the working of the card chain of the card is a known technique, see for example, but not limited to, the exemplified CN206089904U and CN113046866a, etc.
In the present embodiment, the aforementioned feed curtain operating condition responsive wheel 25a is a responsive gear having responsive gear teeth 25c in the circumferential direction of the rim, and the distances between each two adjacent responsive gear teeth 25c are equal.

Under the operation of the fiber feeding curtain driving mechanism 23 of the structure system of the fiber feeding amount self-leveling mechanism 2, as the fiber feeding curtain 24 is correspondingly in a fiber conveying motion state, and the feeding curtain operation state response wheel 25a is used for collecting signals by the feeding curtain operation state response wheel signal collector 25b and feeding the collected signals back to the electric controller, the electric controller gives signals to the front left weighing sensor 26a, the right weighing sensor 26b, the rear left weighing sensor 27a, the rear right weighing sensor 27b, so that the fiber feeding curtain is in a weighing operation state. In the case that the fiber feeding curtain 24 and the four weighing sensors are all in the weighing operation state, if the fiber amount at the left end of the fiber feeding curtain 24 is significantly larger than the fiber amount at the right end, the weight is also heavier than the fiber amount at the right end, and the weight signals are weighed by the front and rear left weighing sensors 26a, 27a and the front and rear right weighing sensors 26b, 27b and fed back to the electric controller, so that the PLC (programmable logic controller) in the electric controller sends signals to the motor 231, thereby accelerating the rotation speed of the motor 231, and correspondingly accelerating the movement speed of the fiber feeding curtain 24, thereby accelerating the fiber feeding speed. Otherwise, the same examples are omitted. From the foregoing, it is apparent that the fiber feed amount self-adjusting mechanism 2 of the present invention can make the amount of nonwoven fibers entering the carding machine main body 1 uniform, and avoid uneven grammage of the final product due to negligence. When the fiber amount at the left and right ends of the fiber feeding curtain 24 does not exceed the weight difference range required by the process, that is, set by the PLC, the fiber feeding curtain 24 is normally operated, that is, the motor 231 is normally operated.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
