Description

Roller cotton feeding device of carding machine
Technical Field
The invention belongs to the technical field of non-woven mechanisms, and particularly relates to a roller cotton feeding device of a carding machine.
Background
The carding machine is also called a carding machine, and is a component of a complete set of non-woven product production equipment. As is known in the art, a complete set of nonwoven product production equipment, such as a nonwoven fabric or a nonwoven felt, mainly includes an opener, a carding machine, a lapping machine and a needle punch (or a spunlace machine), wherein the carding machine is used for carding and outputting nonwoven fibers opened by the opener to a lapping machine for lapping, and the lapping machine sends the nonwoven fibers to the needle punch or sends the nonwoven fibers to the spunlace machine for spunlacing to form a nonwoven product.
Technical information on the carding machine can be found in published chinese patent documents such as CN2697116Y (non-woven carding machine), CN101104965 (semi-worsted slivering machine), CN101294317a (main carding mechanism of non-woven carding machine), CN102995167a (high speed carding machine), CN100510211C (a feeding and carding system of carding machine), CN1313660C (flat carding machine which feeds fibers in multi-path in the form of fiber mat), CN102348840a (carding machine), CN2816061Y (full fixed flat carding machine), CN1811027a (carding machine with cover device which can move in translation), CN102797077a (carding machine of spinning line), CN104153048A (new carding machine) and CN105256411a (non-woven fibers, etc.), carding machine.
In the structural system of the carding machine, the carding machine comprises a chest cylinder (also called a main carding cylinder or a large carding cylinder, see CN 101294317A), a cotton feeding device corresponding to one side of a cotton inlet of the chest cylinder and a cotton discharging device corresponding to one side of a cotton outlet of the chest cylinder, nonwoven fibers opened by an opener are conveyed to the cotton feeding device through an input curtain, are fed to the chest cylinder through the cotton feeding device, are conveyed to the cotton discharging device through the chest cylinder, and are introduced into a lapping machine for lapping.
Technical information on the cotton feeding devices of the carding machines is also found in the published chinese patent documents, and is exemplified by CN101509157B (cotton feeding mechanism of the carding machine), CN202925187U (mechanical feeding device for fiber carding), CN104499115B (cotton feeding device of the carding machine), CN105862182a (cotton feeding device of the carding machine with improved structure), and CN205088360U (roller feeding device for fiber carding machine), etc.
From a reading of the patent literature, which is not limited to the above examples: the upper feed roller, which is customarily referred to as the upper pressure roller, and the lower feed roller, which is customarily referred to as the lower pressure roller, are both important parts of the structural system of the roller feed device and also important factors for determining whether a desired feed of the fibers to the lickerin roller is possible. In general, it is necessary to ensure that the upper and lower feed rollers are as clean as possible.
In the prior art, workers or equipment management personnel usually perform regular cleaning on upper and lower cotton feeding rollers of a roller cotton feeding device of a carding machine, so that the working strength of on-line workers or equipment management personnel is increased on one hand, and the working efficiency of the carding machine is influenced on the other hand. In particular, the surfaces of the upper cotton feeding roller and the lower cotton feeding roller are wound with card clothing, so that the card clothing is careless and easy to damage in the cleaning process. Furthermore, the card clothing of the upper and lower cotton feeding rollers can be cleaned only for a while in a state that the carding machine is stopped, and the upper and lower cotton feeding rollers can not be ensured to be always in a state without fiber winding and embedding in the working process. And, because the effect of cleaning the upper and lower cotton feeding rollers manually is related to the factors of responsibility, experience and emotion of the cleaning personnel, the cleaning degree is often difficult to stabilize.
None of the above patent documents, including patent application publication No. CN106012118a (cotton feeding device of carding machine with function of preventing metal sundries) teaches how to solve the above problems and make the upper and lower cotton feeding rollers always in good clean state. For this reason, the applicant has conducted a long-lasting and useful exploration and repeated compensation, which eventually led to the technical solutions described below and proved to be feasible by computer simulation tests with security measures.

In the present invention, the reason why the clutch mechanism 9 is provided is that: since metal impurities such as screws, nuts, spacers, etc. falling off from the apparatus during the processing of the nonwoven fabric are mixed in (i.e., mingled into) the nonwoven fabric, the damage to the carding machine is serious, even fatal, although the probability of such a situation is relatively low. Since the nonwoven fabric with metal impurities is introduced from between the aforementioned upper and lower feed rollers 5, 6 of the roller feed device of the carding machine of the present invention, the aforementioned upper feed roller clothing 53 and lower feed roller clothing 63, licker-in clothing 23 and intermediate cylinder clothing on the intermediate cylinder 10 (shown in fig. 2), and the like are certainly damaged. However, the clutch mechanism 9 can avoid the destruction of the above-mentioned metal impurities, which is a troublesome reaction, and the specific principle will be further described in the following description of the operation principle of the feed roller driving mechanism 7.
The working principle and the intended technical effect of the feed roller drive mechanism 7 and the feed roller cleaning mechanism 8 according to the invention are described in the following by the applicant in conjunction with fig. 1 to 4.
The motor 71 works, the motor shaft 711 of the motor 71 drives the motor shaft sprocket 72, the lower cotton feeding roller transmission sprocket 73 is driven by the transmission chain 74, the lower cotton feeding roller transmission sprocket 73 is fixedly connected with the left clutch disc 92 through a pair of left clutch disc connecting screws 7321, and the clutch disc seat 91 fixed (fixed in a key matching way) with the lower cotton feeding roller right shaft head 62 of the lower cotton feeding roller 6 is fixedly connected with the right clutch disc 93 through a pair of right clutch disc connecting screws 9131, and further, the left and right clutch discs 92 and 93 are connected through the safety pin 94, so that the lower cotton feeding roller transmission sprocket 73 drives the left clutch disc 92 when moving, the right clutch disc 93 is driven through the safety pin 94, the clutch disc seat 91 is driven by the right clutch disc 93, and the lower cotton feeding roller right shaft head 62 is driven by the clutch disc seat 91, so that the lower cotton feeding roller 6 is in a state of moving in an arrow direction (clockwise) as shown in fig. 1. Meanwhile, the transition transmission gear 75 is driven by the movement of the lower cotton feeding roller right shaft head 62, and since the transition transmission gear 75 is meshed with the upper cotton feeding roller driving gear 76, the transition transmission gear 75 drives the upper cotton feeding roller driving gear 76, and the upper cotton feeding roller driving gear 76 drives the upper cotton feeding roller right shaft head 52, so that the upper cotton feeding roller 5 is in a state of moving in the arrow direction (counterclockwise) as shown in fig. 1. The nonwoven fibers opened by the opener of the preceding step and fed by the feed roller arrangement 20 (shown in fig. 2) are fed by the upper and lower feed rollers 5, 6 to the licker-in 2, from the licker-in 2 to the aforementioned intermediate cylinder (also called "intermediate carding roller"), through a complete carding chain to the output from the output roller (not shown in the figure) for the lapping machine to lap. Meanwhile, in the process of the movement of the cotton feeding roller 6, the lower cotton feeding roller left shaft head chain wheel 831 of the cleaning roller transmission connecting device 83 which is fixed on the lower cotton feeding roller left shaft head 61 and belongs to the structural system of the cotton feeding roller cleaning mechanism 8 is driven, the lower cotton feeding roller left shaft head chain wheel 831 drives the chain wheel transmission chain 833, the chain wheel transmission chain 833 drives the cleaning roller left shaft head chain wheel 832, the cleaning roller left shaft head chain wheel 832 drives the cleaning roller left shaft head 841, so that the cleaning roller 84 moves in the arrow direction (clockwise) shown in the figure 1, and the cleaning roller card clothing 843 on the cleaning roller 84 cleans the lower cotton feeding roller card clothing 63 of the lower cotton feeding roller 6. The fibers entangled and retained on the lower feed roller card clothing 63 are combed off to ensure the smooth operation of the carding chain of the carding machine.
In the process, when the fiber is mixed with metal and/or non-metal impurities, once the impurities enter between the upper cotton feeding roller 5 and the lower cotton feeding roller 6 along with the fiber, the upper cotton feeding roller 5 and the lower cotton feeding roller 6 exceed the rotating torque during normal cotton feeding, at the moment, the safety pin 94 is broken at the position of the fragile and easily broken neck 941 of the safety pin, so that the transmission connection relation of the left clutch disc 92 and the right clutch disc 93 is interrupted, the clutch disc seat 91 does not drive the right shaft head 62 of the lower cotton feeding roller any more, the upper cotton feeding roller 5 and the lower cotton feeding roller 6 stop moving, and the on-line operator sets the intact safety pin 94 after removing the impurities and continues working.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
