Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a same-position needle-punching device for a needle-punching machine. Background Art

[0002] The needle punching machine is a blanket-making device that compacts and needle-punches a refractory fiber blanket of a certain thickness to weave it into a refractory fiber blanket. It uses a triangular or other shaped cross-section and barbed needles with barbed hooks on the edges to repeatedly puncture the fiber web. When multiple needles penetrate the fiber web, the barbed hooks on the needles will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down squeeze the fiber web to a certain extent, causing the fibers in the fiber web to be close together and compressed. In order to increase the compactness of the produced non-woven fabric, it is usually necessary to needle-punch the raw materials of the bottom layer.

[0003] For example, the patent document with the announcement number CN219385542U discloses a co-position piercing device for a needling machine, which starts the motor to drive the first pulley and the first rotating shaft to rotate cyclically, and the two sliders are moved back and forth through the first connecting rod, the connecting block and the second connecting rod, so that the upper and lower outer surfaces of the needle-punched non-woven fibers on the upper and lower sides are pierced, thereby improving the strength of the non-woven fabric. Through the operation of the motor, the first pulley and the second pulley are used to drive the second rotating shaft and the third rotating shaft to rotate, so that the non-woven fibers are compacted and thinned, which is convenient for subsequent needling treatment. By setting a baffle, when the needle is reset, the non-woven fabric tissue on the needle is cleaned to prevent the needle from adhering to the non-woven fabric fiber tissue and affecting the discharge of the non-woven fabric.

[0004] However, during the use of the above patent, when a large amount of non-woven fiber tissue accumulates on the baffle, in order not to affect the subsequent processing and manufacturing, manual cleaning is usually required. However, during the cleaning, there is a possibility that the cleaning personnel may accidentally touch the needles, thereby causing injuries. Utility Model Content

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] The present utility model will be further described below with reference to the accompanying drawings:

[0025] As Figures 1-5 shown, a coaxial counter-piercing device for a needle punching machine includes a base 1. Two vertical plates 101 are welded to the top of the base 1. A plurality of anti-slip pads 102 are connected to the bottom of the base 1 by screws. Two groups of needle punching mechanisms are symmetrically installed up and down between the two vertical plates 101. The two groups of needle punching mechanisms are driven by a belt. A first motor 3 is installed on one side of one of the groups of needle punching mechanisms. Two groups of spring-back mechanisms are arranged between the two groups of needle punching mechanisms. A lifting mechanism for moving up and down is installed on the top of the vertical plate 101. The lifting mechanism includes a fixed frame 501 and a connecting block 504. A cleaning mechanism for cleaning fiber tissue is installed at the bottom of the connecting block 504.

[0026] The needle punching mechanism includes two sliding blocks 201, which are respectively slidably connected in two vertical plates 101. A needle plate 202 is bolted between the two sliding blocks 201. A plurality of needle points 203 are installed at the bottom of the needle plate 202. A baffle 204 is arranged below the needle points 203, and the baffle 204 is bolted between the two vertical plates 101. A rotating shaft 205 is rotatably connected between the two vertical plates 101 through bearings. An eccentric wheel 206 is key-connected to the rotating shaft 205. The first motor 3 is installed on one side of the vertical plate 101 through a bracket. The output shaft of the first motor 3 is connected to one end of the rotating shaft 205 through a coupling. By operating the first motor 3, the rotating shaft 205 in a set of needle punching mechanisms can be driven to rotate. By rotating the rotating shaft 205, the eccentric wheel 206 is driven to rotate, and then the needle plate 202 is driven to move downward by using the sliding block 201. At the same time, the rotating shaft 205 in the other set of needle punching mechanisms can be driven to rotate through belt transmission, so as to drive the other needle plate 202 to move upward, realizing counterpoint needle punching. The rebounding mechanism includes a mounting box 401, which is bolted to one side of the vertical plate 101. Two sliding seats 403 are slidably connected in the mounting box 401. A spring 402 is arranged between the two sliding seats 403. The other ends of the two sliding seats 403 are respectively bolted to the sliding blocks 201 in the two sets of needle punching mechanisms. When the sliding block 201 moves, the sliding seat 403 can be driven to compress the spring 402. At the same time, the spring 402 will generate a rebounding force, which is transmitted to the sliding block 201 through the sliding seat 403, so as to drive the sliding block 201 to reset, and further make the needle plate 202 always keep in contact with the eccentric wheel 206, realizing reciprocating up and down movement.

[0027] The fixing frame 501 is bolted to the tops of the two vertical plates 101. A fixing plate 502 is bolted to the top of the fixing frame 501. An electric push rod 503 is bolted to the bottom of the fixing plate 502. A connecting block 504 is threadedly connected to the output shaft of the electric push rod 503. Slide rails 505 are bolted to the front sides of the two vertical plates 101. A slider 506 is slidably connected in the slide rails 505. The front side of the slider 506 is bolted to the mounting plate 601. By operating the electric push rod 503, the connecting block 504 is driven to move downward, so as to drive the mounting plate 601 to move downward. At the same time, by moving the mounting plate 601 downward, the slider 506 can be driven to slide in the slide rails 505, so that the mounting plate 601 can be lifted and lowered more smoothly.

[0028] The cleaning mechanism includes a mounting plate 601, which is connected to the bottom of the connecting block 504 by screws. A transmission lead screw 602 is mounted on the front side of the mounting plate 601 through a bearing block. A threaded block 603 is threadedly connected to the transmission lead screw 602. The threaded block 603 is slidably connected in the mounting plate 601. A suction box 605 is connected to the rear side of the threaded block 603 by screws. A second motor 604 is mounted on one side of the mounting plate 601 through a bracket. The output shaft of the second motor 604 is connected to one end of the transmission lead screw 602 by a coupling. A vacuum cleaner 606 is connected to the top of the fixed frame 501 by bolts. A connecting pipe 607 is threadedly connected to the front side of the vacuum cleaner 606. The other end of the connecting pipe 607 is connected to the suction box 605. The connecting pipe 607 is a telescopic hose. By operating the vacuum cleaner 606, the suction force is transmitted to the suction box 605 through the connecting pipe 607, and the fibrous tissue on the surface of the baffle 204 is absorbed through the suction box 605. At the same time, by operating the second motor 604, the transmission lead screw 602 is driven to rotate, thereby driving the threaded block 603 to move, and further driving the suction box 605 to move, so as to achieve a comprehensive cleaning of the surface of the baffle 204, avoiding manual cleaning and reducing injuries.

[0029] Working principle: During needling, by operating the first motor 3, the rotating shaft 205 in a group of needling mechanisms can be driven to rotate. By rotating the rotating shaft 205, the eccentric wheel 206 is driven to rotate, and then the needle plate 202 is driven to move downward by the sliding block 201. At the same time, through belt drive, the rotating shaft 205 in another group of needling mechanisms can be driven to rotate, so as to drive another needle plate 202 to move upward, realizing counterpoint needling. When the sliding block 201 moves, the sliding seat 403 can be driven to compress the spring 402. At the same time, the spring 402 will generate a rebound force, which is transmitted to the sliding block 201 through the sliding seat 403, so as to drive the sliding block 201 to reset, and further make the needle plate 202 always keep in contact with the eccentric wheel 206, realizing up and down reciprocating movement. When it is necessary to clean the fibrous tissue on the surface of the baffle 204 after the needling work is completed, by operating the electric push rod 503, the connecting block 504 is driven to move downward, thereby driving the mounting plate 601 to move downward. At the same time, by moving the mounting plate 601 downward, the slider 506 can be driven to slide in the slide rail 505, so that the mounting plate 601 can be lifted and lowered more smoothly. After the mounting plate 601 moves downward to the position between the two baffles 204, by operating the vacuum cleaner 606, the suction force is transmitted to the suction box 605 through the connecting pipe 607, and the fibrous tissue on the surface of the baffle 204 is absorbed through the suction box 605. At the same time, by operating the second motor 604, the transmission lead screw 602 is driven to rotate, thereby driving the threaded block 603 to move, and further driving the suction box 605 to move, so as to achieve a comprehensive cleaning of the surface of the baffle 204, avoiding manual cleaning and reducing injuries.
