Description

Technical Field

[0001] The invention belongs to the technical field of nonwoven machinery, and in particular relates to a pile needle loom with a net inlet having a dust suction function. Background Art

[0002] The aforementioned pile needle loom is also called jacquard pile needle loom, pile jacquard needle loom or needle jacquard pile loom. Needle looms are well known in the industry and are widely mentioned in the public Chinese patent literature, such as CN101492861B (automatic multifunctional needle loom), CN102373579B (endless needle loom), CN102677397B (structurally improved double-axis needle loom), CN102677398A (double-axis needle loom), CN102808290B (drum-type needle loom), CN106087258B (double-sided needle loom), CN105734836A (a low-noise needle loom), CN106087259A (a high-speed double-axis guided eccentric needle loom) and CN106988023A (a small-diameter blanket cover needle loom), etc. However, it is not limited to the aforementioned patents that all do not have the raising function.

[0003] The pile needle loom is developed or evolved on the basis of the above-mentioned needle loom. Because some non-woven products, such as carpets, need to have one of their surfaces raised, otherwise the elasticity or softness of the carpet cannot be reflected. Therefore, the structure system of the pile needle loom generally has a brush curtain called a "ring curtain" that has no end and moves repeatedly in a working state (see CN2617795Y "Pile Needle Loom" and "Brush Transmission Mechanism of Pile Needle Loom" provided in CN2637520Y). The brush curtain is composed of many brushes organically combined, and its function can be fully understood by reading the patent documents which are not limited to the following examples, such as CN202181428U (brush cleaning device for pile needle punching machine), CN108625044B (a double-axis needle punching machine for textile), CN108179552A (jacquard pile needle punching machine) and CN108085875A (jacquard pile needle punching machine with improved structure), etc.

[0004] By reading the above patent documents related to the pile needle loom and combining it with professional common sense, it can be known that during the needling process, the following undesirable but objectively unavoidable problems often occur: First, the fiber short fibers will accumulate between the bristles of the brush constituting the brush curtain; second, the short fibers will entangle the brush filaments. The former will have a certain impact on the holding force and release force of the brush filaments, and the latter will entangle the brush filaments in severe cases, causing the release force to be seriously affected. Both of the above situations will have an adverse effect on the quality of the pile non-woven products and will also damage the service life of the brush to a certain extent. The "brush curtain impurity removal and cleaning device for pile needle loom" recommended by CN202181428U and the "high-frequency pile needle loom" recommended by CN105256467B can remove impurities from the brush curtain by impurity removal rollers. For details, please refer to paragraphs 0015-0018 and paragraph 0064 of the specifications of these two patents respectively. The two patent solutions are undoubtedly effective in removing fibers of a certain length, because they can comb the brush like a combing hair, and remove short fibers entangled in the brush filaments and accumulated between the brush filaments. However, since the steel needles on the impurity removal roller must maintain a certain gap with the brush plate, otherwise the steel needles will damage the brush plate, the fiber dust or fiber impurities generated during the needling process are often difficult or even impossible to be combed out by the aforementioned steel needles after being attached to the brush plate, and stubborn scale will form on the surface of the brush plate over time, and the cohesive force and release elasticity of the brush filaments on the brush will gradually decline. At present, the main method to solve the above-mentioned problems is to use industrial vacuum cleaners or similar vacuuming equipment to perform manual cleaning regularly or irregularly. One of the shortcomings of this method is that it unnecessarily increases the workload of online operators or professional equipment maintenance personnel; second, since the cleaning is carried out in a shutdown state, it will affect the equipment, that is, the working efficiency of the pile needle loom; third, since the scale formed over time is relatively stubborn, the effect of regular or irregular cleaning cannot meet the expected requirements; fourth, since human beings are involved in cleaning, the quality of cleaning often varies from person to person and cannot be considered with reasonable indicators. In view of the above situation, it is necessary to make improvements. For this reason, the applicant has made persistent and beneficial explorations and repeated designs. The technical solution to be introduced below was produced in this context. Summary of the invention

[0020] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description in the form of embodiments below. However, the description of the embodiments is not a limitation of the present invention. Any equivalent changes made based on the concept of the present invention that are merely formal and not substantial should be regarded as within the scope of the technical solution of the present invention.

[0021] In the following description, all concepts related to up, down, left, right, front and back directions or orientations are based on Figure 1 The position state is taken as a reference, and thus it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0022] See also Figure 1 , showing a frame 1, a raising mechanism 2, a needling mechanism 3, a stripping plate 4, a stripping plate lifting and adjusting mechanism 5, a needle beam driving mechanism 6 and a pulling mechanism 7, a screen inlet 11 is formed on the left side of the frame 1 and at a position corresponding to the raising mechanism 2, and a screen outlet 12 is formed on the right side of the frame 1 and at a position corresponding to the pulling mechanism 7, the needle beam driving mechanism 6 is arranged at the top of the frame 1 in the height direction, the needling mechanism 3 corresponds to between the raising mechanism 2 and the needle beam driving mechanism 6 and is connected to the needle beam driving mechanism 6, the raising mechanism 2 is arranged on the aforementioned frame 1 at a position corresponding to between the aforementioned screen inlet 11 and the screen outlet 12 and is located below the aforementioned needling mechanism 3, the raising mechanism 2 has a brush curtain 21, the stripping plate 4 is connected to the stripping plate lifting and adjusting mechanism 5 at a position corresponding to between the brush curtain 21 and the needling mechanism 3 and the stripping plate 4 is in a grid structure, and the stripping plate lifting and adjusting mechanism 5 is arranged on the side of the frame middle crossbeam 13 of the frame 1 facing the aforementioned raising mechanism 2.

[0023] The brush curtain 21 mentioned above can be essentially called a ring curtain. Its specific structure and function can be found in the patent literature mentioned by the applicant in the background technology column above. That is to say, since the structure and working principle of the pile raising mechanism 2 and its brush curtain 21 belong to the prior art, the applicant will not elaborate on them. The acupuncture mechanism 3, the stripping plate 4, the stripping plate lifting adjustment mechanism 5, the needle beam of the structural system of the acupuncture mechanism 3 and the needle beam driving mechanism 6 that moves the needle bed up and down, and the pulling mechanism 7 mentioned above also belong to the prior art. For example, you can refer to CN108085875A, CN108179552A, CN202181428U and CN105256467B mentioned above, so the applicant will not repeat them.

[0024] The technical key points of the technical solution provided by the present invention are as follows: the structural system of the napping needle loom with a dust suction function at the aforementioned air inlet also includes a brush curtain dust suction mechanism 8, which is arranged on the aforementioned frame 1 at a position corresponding to the aforementioned mesh inlet 11 and corresponds to the width direction of the aforementioned brush curtain 21.

[0025] See also Figure 3 A circular brush curtain dust suction tube support hole 14 is provided on the wall facing the aforementioned network inlet 11 of the aforementioned frame 1, and the aforementioned brush curtain dust suction mechanism 8 is supported on the brush curtain dust suction tube support hole 14 in a state corresponding to the left side in the width direction of the aforementioned brush curtain 21.

[0026] See also Figure 2 The brush curtain dust suction mechanism 8 comprises a dust suction pipe 81, a dust suction pipe cavity airway plate 82 and a dust suction nozzle 83. A dust outlet 811 is extended 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 pipeline when in use. The dust suction pipe cavity airway plate 82 is arranged in the dust suction pipe cavity 812 of the dust suction pipe 81, and the dust suction pipe cavity airway plate 82 is arranged in the dust suction pipe cavity 812 of the dust suction pipe 81. The distance between the plate 82 and the dust suction nozzle 83 increases symmetrically from the middle of the length direction of the dust suction tube cavity airway plate 82 toward the aforementioned dust outlet 811. This structure has a trumpet effect from small to large, which can enhance the turbulence of the dust suction airflow and meet the excellent dust suction requirements. The dust suction nozzle 83 is formed on the side of the suction port 831 facing the aforementioned brush curtain 21. The dust suction nozzle 83 is communicated with the dust suction tube cavity 812 and at the same time corresponds to the left side of the brush curtain 21 in the width direction.

[0027] Depend on Figure 2 As shown in the diagram, the suction nozzle 83 is directed toward Figure 1 The width of the suction port 831 in the length direction of one side of the brush curtain 21 is relatively narrow, that is, it is like a gap, so that dust between the bristles of the brush constituting the brush curtain 21 can be effectively sucked out.

[0028] Depend on Figure 3 As shown, a dust suction pipe reinforcement fixing frame 15 is preferably fixed by welding on the wall facing the aforementioned network inlet 11 of the aforementioned frame 1 and at a position corresponding to the lower side of the aforementioned brush curtain dust suction pipe support hole 14, and a pair of dust suction pipe reinforcement fixing screws 151 are provided on the dust suction pipe reinforcement fixing frame 15, and one end and the other end of the aforementioned dust suction pipe 81 are respectively fixed with a pair of dust suction pipe reinforcement fixing screws 151.

[0029] Depend on Figure 2As shown, a pair of dust suction pipe screw holes 813 are respectively provided at one end and the other end of the dust suction pipe 81 and at positions corresponding to the pair of dust suction pipe reinforcement fixing screws 151. The pair of dust suction pipe screw holes 813 are fixed with the pair of dust suction pipe reinforcement fixing screws 151. The cross-sectional shape of the dust suction pipe 81 is rectangular, and the shape of the dust outlet 811 is a truncated cone; the shape of the dust suction pipe cavity airway plate 82 is V-shaped; and the shape of the dust suction nozzle 83 is flat. The negative pressure dust suction device is a negative pressure fan, but a vacuum pump can also be used.

[0030] Still by Figure 2 As shown, one end of the frustum with a large diameter faces the dust suction pipe 81 and is welded to the dust suction pipe 81, while one end of the frustum with a small diameter extends to the outside of the brush curtain dust suction pipe supporting hole 14 and is connected to the negative pressure dust suction device through a pipeline.

[0031] When the pile needle loom is in working state, that is, the aforementioned needle beam driving mechanism 6 (also called connecting rod mechanism) drives the needle beam of the needle mechanism 3 to move up and down, and the needle beam drives the needle bed fixed on the side facing downward to move up and down accordingly, and the needles arranged on the needle bed needle-punch the pile fabric located between the stripping plate 4 and the brush curtain 21. Since the fiber dust (dust) in the fibers constituting the pile fabric will enter between the bristles of the brush constituting the brush curtain 21, when the brush curtain 21 is in working state, since the dust outlets 811 at both ends of the dust suction pipe 81 of the structural system of the brush curtain dust suction mechanism 8 are connected to the pipeline of the negative pressure dust suction device, the negative pressure dust suction device in working state generates negative pressure on the dust suction pipe 81, and at the same time, the fiber dust entering between the bristles is sucked out by the dust suction nozzle 83 and enters the dust suction pipe cavity 812, and is led out through the dust outlet 811. When the pile needle loom stops working, the negative pressure dust suction device also stops working, and the dust suction pipe 81 stops suctioning dust.

[0032] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
