Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a raised needling machine with a net inlet having a brush cleaning function.
Background
The aforementioned fleece-needle loom is also known as a jacquard fleece-needle loom, a fleece-jacquard needle loom or a needle-punched jacquard fleece-machine. Needling machines are well known in the art and are not known in the published chinese patent literature, and are exemplified by CN101492861B (automated multifunctional needling machine), CN102373579B (endless needling machine), CN102677397B (structurally modified double-shaft needling machine), CN102677398a (double-shaft needling machine), CN102808290B (drum needling machine), CN106087258B (double-sided needling machine), CN105734836A (a low noise needling machine), CN106087259a (a high-speed double-shaft-oriented ectopic pair needling machine) and CN106988023a (a small-diameter blanket-covering needling machine), and the like. However, the above-mentioned patent is not limited to the above-mentioned patent, and does not have a napping function.
The fleece needling machine was developed or evolved based on the needling machine described above, since for certain nonwoven products it is typically necessary to pile one of its faces, such as carpets, which otherwise would not be elastic or flexible, so that there is a hairbrush curtain known as a "ring curtain" which is endless and moves cyclically in the operating state in the structure of the fleece needling machine (see CN2617795Y (fleece needling machine) and CN2637520Y provided "hairbrush drive mechanism of fleece needling machine"). The brush curtain is formed by combining a plurality of brush organic matters, and the functions of the brush curtain can be fully understood through reading the patent documents which are not limited to the following examples, such as CN202181428U (brush impurity removing and cleaning device of a napping needle loom), CN108625044B (a double-shaft needle loom for spinning), CN108179552A (jacquard napping needle loom) and CN108085875A (jacquard napping needle loom with improved structure), and the like.
As can be seen from the reading of the above patent documents on the fleece needling machine and the combination of common general knowledge, the following problems, which are undesirable but objectively unavoidable, often occur during the needling process: firstly, fiber flock can accumulate between brush filaments of a brush forming a brush curtain; secondly, the short fibers can wind the brush filaments. The former can have a certain influence on the cohesion and release force of the brush filaments, and the latter can have a serious influence on the release force by winding the brush filaments when serious. Both of the foregoing conditions can adversely affect the quality of the raised nonwoven product and can also to some extent compromise the useful life of the brush.
The high-frequency raised needling machine recommended by CN105256467B is provided with a brush cleaning device, brush bristles are bent and spread by the brush cleaning device through a scraping plate of the brush cleaning device when the brush is cleaned, and impurities such as fiber scraps attached to the bristles are sprung and flown in the process of recovering to a straightened state after the bent bristles pass over the scraping plate, so that the purpose of cleaning a brush curtain is achieved. However, the brush cleaning device disclosed in this patent has the following technical problems: firstly, the device is positioned below one side of the brush curtain facing the net inlet at one side of the frame, so that the distance from the corner of the lower part of the brush curtain is relatively long, and the stability and reliability of the scraping plate on the cleaning action of the brush can be affected to a certain extent; secondly, because the distance of brush cleaning device from the brush curtain is farther, owing to reflect the stability to the brush cleaning action as far as possible again, consequently cause whole brush cleaning device's structure comparatively complicated and the action transmission link is many, on the one hand increased the device cost, on the other hand still can increase and examine and protect work load and because the action transmission link is many and cause the energy consumption to increase, thirdly, owing to brush cleaning device structure complicacy and whole volume are big, consequently can produce adverse effect to the succinct nature of raising knitting machine structure equally. In view of the foregoing, there is a need for reasonable improvements, and the technical solutions described below are created in this context.

Please refer to fig. 2 in combination with fig. 1, which is a technical point of the technical scheme provided by the present invention: the brush cleaning device 8 includes a pair of cylinder fixing plates 81, a pair of cylinder fixing plates 82, a pair of scraper fixing arms 83 and a scraper 84, the pair of cylinder fixing plates 81 are each fixed to the facing wall of the frame 1 by cylinder fixing plate bolts 812 at positions corresponding to the inlet 11, the pair of cylinder fixing plates 82 are fixed to opposite sides of the pair of cylinder fixing plates 81 with the cylinder posts 821 of the pair of cylinder fixing plates 82 facing the brush curtain 21, the scraper fixing arms 83 are fixed to the ends of the cylinder posts 821 of the pair of cylinder 82, and the scraper 84 is fixed to the scraper fixing arms 83 and corresponds to the width direction of the end of the brush curtain 21 facing the inlet 11.
As shown in fig. 2, a cylinder fixing base connecting plate 811 is formed at each of the positions corresponding to the opposite sides of the pair of cylinder fixing plates 81 facing one end of the brush curtain 21, the cylinder fixing base connecting plate 811 is perpendicular to the cylinder fixing plates 81, the pair of cylinders 82 are fixed to the cylinder fixing base connecting plate 811 by cylinder fixing bases 822 in a horizontal position, and the cylinder column 821 passes through the cylinder fixing base 822 and the cylinder fixing base connecting plate 811 in order to fix the squeegee fixing arm 83. Also shown in fig. 2 are cylinder mount bolts 8221 for securing cylinder mount 822 to cylinder mount connection plate 811.
A blade fixing arm step groove 831 is formed at an upper portion of the blade fixing arm 83 and at a position corresponding to the blade 84, the blade fixing arm step groove 831 extends from one end to the other end of the blade fixing arm 83, the blade 84 is fixed to the blade fixing arm step groove 831 at a position corresponding to a blade fixing screw hole 8311 preset at the blade fixing arm step groove 831 by a blade fixing screw 841 arranged at intervals, and the blade 84 protrudes out of the blade fixing arm step groove 831 in a longitudinal direction toward one side of the brush curtain 21.
Preferably, a blade slope 842 may be formed in a longitudinal direction of a side of the blade 84 facing the brush curtain 21.
In the present embodiment, the pair of the working cylinders 82 are air cylinders.
In the state where the brush curtain 21 is in the periodically moving state, that is, in the state where the raising needling machine is in the operating state, the action cylinder bars 821 are pushed by the action cylinders 82 of the structural system of the brush cleaning device 8 to push the blade fixing arms 83, the blade fixing arms 83 are displaced together with the blade 84 in the direction of the brush curtain 21, the blade 84 is made to penetrate into the bristles of the brush curtain 21, and the pair of action cylinders 82 at this time are in the pressed state so as to ensure that the blade 84 cleans the moving brush curtain 21, specifically: when the brush of the brush curtain 21 passes through the position of the scraping plate 84, the brush hairs are bent and spread, and after passing over the scraping plate 84, the bent brush hairs pop out fiber dust and the like attached in the brush hairs in the process of quick return, namely quick straightening. In the stop state of the pile needle machine, the brush curtain 21 does not move any more, so that the pair of acting cylinders 82 need to work again, and the acting cylinder 821 drives the scraper fixing arm 83 and the scraper 84 to retract away from the brush curtain 21, so that the phenomenon that bristles on the brush are pressed and deformed to be unrecoverable is avoided.
As is known in the art, because of the foregoing deficiencies of the brush cleaning apparatus 8 architecture in which it is difficult to adequately clean the bristles from the fibrous debris, particularly the fibrous debris which may collect on the brush plate in the form of stubborn foulants, it is often desirable to perform periodic or unscheduled manual cleaning, such as by using an industrial cleaner or other similar cleaning equipment, which does not add significant effort to the work of on-line operators or equipment care personnel, such as clamp-on workers. In addition, the manual cleaning is performed in a stop state, so that the working efficiency of the raised needling machine is affected to a certain extent; the scale formed by accumulation in the daily period is relatively stubborn, and the cleaning effect is difficult to reach the expectations; the effect of the human participation in cleaning also tends to vary from person to person, i.e. the difference is relatively large. In view of the foregoing, a brush curtain dust suction mechanism 9 is provided on the frame 1 at a position corresponding to the intake port 11, the brush curtain dust suction mechanism 9 corresponding to an upper side of the blade fixing arm 83 of the brush cleaning device 8 and also corresponding to a width direction of the brush curtain 21.
Referring to fig. 4, a circular brush curtain suction pipe supporting hole 14 is formed in each of the opposite walls of the frame 1 at the inlet 11, the brush curtain suction mechanism 9 is supported by the brush curtain suction pipe supporting hole 14 in a state corresponding to the left side of the brush curtain 21 in the width direction, and the brush curtain suction mechanism 9 is also corresponding to the upper side of the scraper fixing arm 83.
Referring to fig. 3, the brush curtain suction mechanism 9 includes a suction pipe 91, a suction pipe cavity air passage plate 92 and a suction nozzle 93, wherein the suction pipe 91 is extended with a dust outlet 911 corresponding to the upper side of the blade fixing arm 83, the dust outlet 911 is supported on the brush curtain suction pipe supporting hole 14 and the dust outlet 911 is connected with a negative pressure suction device as a peripheral auxiliary device through a pipe in a use state, the suction pipe cavity air passage plate 92 is disposed in a suction pipe cavity 912 of the suction pipe 91, and a space between the suction pipe cavity air passage plate 92 and the suction nozzle 93 is gradually increased from a middle part of the suction pipe cavity air passage plate 92 in a length direction toward the dust outlet 911 in a symmetrical state, the structure is provided with a sharp effect of enhancing a suction air flow by a small and large bell mouth effect, the suction nozzle 93 is formed on a side of the suction pipe 91 toward the brush curtain 21, and the suction nozzle 93 is communicated with the suction pipe cavity and simultaneously corresponds to a width direction of the brush curtain 21.
As is clear from the illustration of fig. 3, the suction nozzle 93 has a relatively narrow width toward the suction port 931 in the longitudinal direction on the side of the brush curtain 21 shown in fig. 1, i.e., a slit-like condition, so that the dust and dirt between the brush filaments constituting the brush of the brush curtain 21 can be effectively sucked out.
As shown in fig. 4, a suction pipe reinforcing mount 15 is fixed to the wall body of the frame 1 facing each other at the inlet 11 and at a position corresponding to the lower part of the brush curtain suction pipe support hole 14 by welding, a pair of suction pipe reinforcing fixing screws 151 are disposed on the suction pipe reinforcing mount 15, and one end and the other end of the suction pipe 91 are fixed to the pair of suction pipe reinforcing fixing screws 151.
As shown in fig. 3, a pair of suction pipe screw holes 913 are formed at one end and the other end of the suction pipe 91 at positions corresponding to the pair of suction pipe reinforcing fixing screws 151, respectively, and the pair of suction pipe screw holes 913 are fixed to the pair of suction pipe reinforcing fixing screws 151; the dust suction pipe 91 has a rectangular cross section, and the dust outlet 911 has a truncated cone shape; the dust suction lumen airway plate 92 has a V-shape; the shape of the dust suction nozzle 93 is flat; the negative pressure dust collection device is a negative pressure fan, but a vacuum pump can also be used.
Still referring to fig. 3, the end of the truncated cone shape having a large diameter faces the suction pipe 91 and is welded to the suction pipe 91, and the end of the truncated cone shape having a small diameter extends out of the brush curtain suction pipe supporting hole 14 and is connected to the vacuum cleaner by a pipe.
In the working state of the pile needle machine, that is, the needle beam driving mechanism 6 (also called as a link mechanism) drives the needle beam of the needle punching mechanism 3 to move up and down, the needle beam drives the needle bed fixed on the downward side of the needle bed to move up and down correspondingly, and the pile fabric positioned between the stripping net plate 4 and the brush curtain 21 is needled and raised by the needles arranged on the needle bed. Since the fiber dust (dust) in the fibers constituting the raised fabric is introduced between the brush filaments constituting the brush of the brush curtain 21, in the operating state of the brush curtain 21, the negative pressure suction device is operated to generate negative pressure to the suction tube 91 by the negative pressure suction device in the operating state since the dust outlet 911 at both ends of the suction tube 91 of the structural system of the brush curtain suction mechanism 9 is connected to the negative pressure suction device by the pipe line, and at the same time, the fiber dust introduced between the brush filaments is sucked by the suction nozzle 93 and introduced into the suction tube chamber 912, and is discharged through the dust outlet 911. When the napping needling machine stops working, the negative pressure dust collection device also stops working, and the dust collection pipe 91 stops collecting dust.
The advantages of the brush curtain dust collection mechanism 9 mentioned above, namely the technical effects, can be summarized as follows: firstly, when the brush curtain 21 is in a moving state, the brush curtain is sucked in an automatic mode by a brush curtain dust suction mechanism 9 which is positioned at the net inlet 11 of the frame 1 and corresponds to the width direction of the brush curtain 21, so that fiber dust entering between brush filaments of a brush forming the brush curtain 21 is timely sucked, and scale formation caused by accumulation can be avoided; secondly, the brush curtain dust collection mechanism 9 and the brush curtain 21 work simultaneously, so that shutdown cleaning is not needed, and the working efficiency of the equipment is ensured; because the brush curtain dust collection mechanism 9 utilizes negative pressure to collect dust, the brush curtain 21 has ideal cleaning effect, so that the cohesive force and the release force of the brush wires are ensured not to decline due to the time; thirdly, since the dust collection process of the brush curtain 21 is not manually participated, the desired cleaning quality is ensured without the difference of the cleaning degree.
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.
