Description

Raising needling machine with net inlet having dust absorption function

Technical Field

The utility model belongs to the technical field of nonwoven machinery, concretely relates to net inlet has dust absorption function's teasing needle loom.

Background

The aforementioned teasing needle machines are also called jacquard teasing needle machines, teasing jacquard needle machines or needle jacquard needle machines. Needle machines are well known in the art and are not described in the published chinese patent literature, to name but a few, CN101492861B (automated multi-function needle machine), CN102373579B (endless needle machine), CN102677397B (structurally modified double-shaft needle machine), CN102677398A (double-shaft needle machine), CN102808290B (drum-type needle machine), CN106087258B (double-sided counter-needling machine), CN105734836A (a low-noise needle machine), CN106087259A (a high-speed double-shaft guiding counter-needling machine), and CN106988023A (a small-diameter blanket-in-blanket needle machine), etc. But not limited to, none of the aforementioned exemplified patents have a napping function.

The pile needle machine is developed or evolved based on the above needle machine, because for some nonwoven products, such as carpet, one of its faces needs to be brushed, otherwise the elasticity or softness of the carpet cannot be reflected, so that it is common to have an endless brush curtain, which is called a "ring curtain", moving in a cycle under working condition in the structural system of the pile needle machine (see "brush driving mechanism of pile needle machine" provided in CN2617795Y and CN 2637520Y). The brush curtain has a plurality of brushes organically combined, and the function of which can be fully understood by reading the patent documents not limited to the following examples, such as CN202181428U (brush cleaning device of a teasing needle machine), CN108625044B (a textile double-shaft needle machine), CN108179552A (jacquard teasing needle machine), and CN108085875A (structurally modified jacquard teasing needle machine), and so on.

From a reading of the above-mentioned patent documents relating to napping needle machines, in combination with the general knowledge in the art, it is known that during the needling process, the following problems are often encountered, which are both undesirable and objectively unavoidable: firstly, the short fiber can be accumulated between the hairbrush filaments of the hairbrush forming the hairbrush curtain; secondly, the short fibers can wind the brush filaments. The former will have a certain influence on the cohesion and release of the brush filaments, and the latter will, in severe cases, entangle the brush filaments and seriously affect the release. Both of the aforementioned conditions adversely affect the quality of the raised nonwoven product and also impair the useful life of the brush to some extent. The CN202181428U recommended cleaning device for brush curtain of raising needle machine and CN105256467B high frequency raising needle machine can remove impurities from brush curtain by impurity removing roller, which can be referred to paragraph 0015 and paragraph 0018 and paragraph 0064 of the specifications of these two patents. Both of these patent solutions are undoubtedly effective in removing the impurities from the fibers having a certain length, since they are capable of combing the bristles in a comb-like effect, removing the short fibers entangled in the brush filaments and accumulated between the brush filaments. However, since a certain gap is required to be maintained between the steel needle on the impurity removing roller and the brush plate, otherwise, the steel needle may damage the brush plate, so that fiber dust or fiber dust generated in the needling process is often difficult to remove or even impossible to remove by the steel needle after being attached to the brush plate, and stubborn scale deposits may be formed on the surface of the brush plate with the passage of time, and the cohesion and release elasticity of the brush filaments on the brush gradually decline. At present, the method for solving the problems mainly adopts an industrial dust collector or similar dust collection equipment to carry out manual operation cleaning regularly or irregularly, one of the defects of the mode is that the workload of online operators or professional equipment maintainers is increased without any reason; secondly, because the cleaning is carried out in a stop state, the working efficiency of the raising needling machine can be influenced; thirdly, the scale formed by the daily accumulation and the monthly accumulation is relatively stubborn, so that the effect of regular or irregular cleaning cannot meet the expected requirement; fourthly, because of the manual cleaning, the degree of the cleaning is different from person to person and cannot be considered by reasonable indexes. In view of the foregoing, there is a need for improvement, and for the applicant to make a long-lasting and useful search and repeat design, the technical solutions described below have been made in this context.

As the technical scheme provided by the utility model: the structural system of the raising needle machine with the dust suction function at the air inlet also comprises a brush curtain dust suction mechanism 8, and the brush curtain dust suction mechanism 8 is arranged on the frame 1 at a position corresponding to the net inlet 11 and corresponds to the width direction of the brush curtain 21.

Referring to fig. 3, a circular brush curtain dust suction pipe support hole 14 is formed in each of the facing wall bodies of the frame 1 at the screen inlet 11, and the brush curtain dust suction mechanism 8 is supported by the brush curtain dust suction pipe support hole 14 in a state corresponding to the left side in the width direction of the brush curtain 21.

Referring to fig. 2, the brush curtain dust suction mechanism 8 includes a dust suction pipe 81, a dust suction pipe chamber air duct plate 82 and a dust suction nozzle 83, a dust outlet 811 extends from one end and the other end of the dust suction pipe 81, the dust outlet 811 is supported on the brush curtain dust suction pipe support hole 14, and the dust outlet 811 is connected to a negative pressure dust suction device as a peripheral auxiliary device through a pipe line in a use state, the dust suction pipe chamber air duct plate 82 is disposed in the dust suction pipe chamber 812 of the dust suction pipe 81, and a distance between the dust suction pipe chamber air duct plate 82 and the dust suction nozzle 83 is increased from a middle portion of the length direction of the dust suction pipe chamber air duct plate 82 toward the dust outlet 811 in a symmetrical state, which has a small and large trumpet effect to enhance a turbulent effect of suction air flow and satisfy excellent dust suction requirements, the dust suction nozzle 83 is formed on a side of the dust suction pipe 81 toward the brush curtain 21, the suction nozzle 83 communicates with the suction chamber 812 and at the same time corresponds to the left side in the width direction of the brush curtain 21.

As is apparent from the schematic view of fig. 2, the suction port 831 of the suction nozzle 83 facing the longitudinal direction from one side of the brush curtain 21 shown in fig. 1 is relatively narrow, i.e., in the form of a slit, so that dust and dirt between the brush filaments of the brushes constituting the brush curtain 21 can be effectively sucked out.

As shown in fig. 3, a suction pipe reinforcing and fixing frame 15 is preferably fixed by welding to each of the facing wall bodies of the frame 1 at the position corresponding to the lower side of the brush curtain suction pipe support hole 14, a pair of suction pipe reinforcing and fixing screws 151 are disposed on the suction pipe reinforcing and fixing frame 15, and one end and the other end of the suction pipe 81 are fixed to the pair of suction pipe reinforcing and fixing screws 151, respectively.

As shown in fig. 2, a pair of suction pipe screw holes 813 are formed at one end and the other end of the suction pipe 81 and at positions corresponding to the pair of suction pipe reinforcing and fixing screws 151, respectively, the pair of suction pipe screw holes 813 are fixed to the pair of suction pipe reinforcing and fixing screws 151, the cross-sectional shape of the suction pipe 81 is rectangular, and the shape of the dust outlet 811 is a truncated cone; the air duct plate 82 of the dust collection pipe cavity is V-shaped; the dust suction nozzle 83 is flat.

When the teasing needle machine is in a working state, i.e. the needle beam driving mechanism 6 (also called a link mechanism) drives the needle beam of the needling mechanism 3 to move up and down, the needle beam drives the needle bed fixed on the downward side to correspondingly move up and down, and the teasing fabric between the screen peeling plate 4 and the brush curtain 21 is teased by the needles arranged on the needle bed. Since fiber dust (dirt) in the fibers constituting the pile fabric enters between the brush wires of the brushes constituting the brush curtain 21, when the brush curtain 21 is in a working state, the suction ports 811 at both ends of the suction pipe 81 of the structural system of the brush curtain dust suction mechanism 8 are connected to the negative pressure suction device pipeline, so that the negative pressure suction device in the working state generates negative pressure to the suction pipe 81, and at the same time, the fiber dirt entering between the brush wires is sucked out by the suction nozzle 83, enters the suction pipe chamber 812, and is led out through the dust outlet 811. When the raising needle loom stops working, the negative pressure dust suction device also stops working, and the dust suction pipe 81 stops sucking dust.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
