Description

Technical Field

[0001] This utility model belongs to the field of aluminum silicate fiber blanket production technology, specifically relating to a needle punching machine used in an aluminum silicate fiber blanket production line. Background Technology

[0002] Alumina silicate fiber blankets are made primarily from alumina silicate fibers. Alumina silicate fiber is a man-made inorganic fiber composed of alumina (Al2O3) and silicon dioxide (SiO2), and usually small amounts of fluxes and other additives are added to improve fiber performance and production processes.

[0003] Existing aluminosilicate fiber blanket production lines require needle punching machines. These machines use barbed needles to repeatedly puncture the aluminosilicate fiber blanket, causing the fibers to entangle and thus reinforcing the blanket. However, during the needle punching process, the needles carry the fibers through the fiber web, resulting in frequent and close contact and friction between the needles and fibers. This allows fibers to adhere to the needle surface, which can affect the machine's efficiency and product quality. It may lead to increased punching force, uneven fiber entanglement, and defects in the fiber web. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention incorporates a cleaning mechanism. During the needle-punching process, a high-pressure blower generates a high-pressure airflow that enters the air outlet pipe, then flows through the air outlet hopper to the upper limit plate. When the needle head is raised, the airflow blows down the fibers attached to the surface of the needle head, which are then blown together with the airflow to the connecting frame on the right end and then discharged through the air outlet frame on the right end. This process removes the fibers attached to the outside of the needle head during the puncturing of the aluminosilicate fiber blanket, thus preventing any interference with the puncturing operation of the aluminosilicate fiber blanket.

[0018] This invention incorporates an anti-clogging unit. When fiber-laden airflow enters the outlet frame from the left and is filtered and discharged through the filter screen at the right, the airflow drives the fan blades to rotate. This rotation causes the first round rod and the driving bevel gear to rotate, which in turn drives the driven bevel gear, which in turn drives the second rotating rod. This causes the driving and driven gears to rotate relative to each other, driving the reciprocating screw to rotate. Consequently, the sliding shuttle and scraper at the outer end of the reciprocating screw move back and forth, simultaneously sliding along the left side of the filter screen. This pushes the fibers trapped on the left side of the filter screen towards the front and rear ends on the left side, preventing continuous fiber accumulation and clogging, thus ensuring the continuous and effective operation of the fiber filtration process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a needle punching machine used in an aluminum silicate fiber blanket production line, and its structural schematic diagram is shown below. Figures 1 to 3As shown, the device includes an outer shell 1, an inner shell 2 fixedly connected inside the outer shell 1, and transmission rollers 6 installed at the front and rear ends of the inner side of the inner shell 2. Needle-punching mechanisms are provided at the inner and outer ends of the outer shell 1 and the inner shell 2. The needle-punching mechanism includes a rotating shaft 301 rotatably connected to the upper left and right ends of the inner shell 1. A U-shaped rod 302 is fixedly connected to the end of the rotating shaft 301 away from the outer shell 1, and a connecting rod 303 is fixedly connected to the adjacent ends of the two U-shaped rods 302. A driven pulley 304 is fixedly connected to the middle position of the outer side of the connecting rod 303. A first motor 305 is installed on the upper side of the outer shell 1, and the left end of the output shaft of the first motor 305 is fixedly... A drive pulley 306 is fixedly connected to the drive pulley 304. A belt 307 is sleeved on the outer end of the drive pulley 306 and the driven pulley 304. A round tube 308 is rotatably connected to the outer side of the U-shaped rod 302. A connecting plate 309 is fixedly connected to the outer side of the round tube 308. A sliding plate 310 is hinged to the lower end of the connecting plate 309. Needle heads 311 are fixedly connected to the lower end of the sliding plate 310 at equal intervals. A bracket 312 is fixedly connected to the bottom inner side of the inner shell 2. A lower limit plate 313 is fixedly connected to the upper end of the bracket 312. An upper limit plate 314 is fixedly connected to the inner side of the inner shell 2 at the position above the lower limit plate 313. The upper left and right ends of the inner shell 2 are provided with through grooves. The left and right sides of the sliding plate 310 are slidably connected to the left and right ends of the inner side of the inner shell 2. The front and rear sides of the sliding plate 310 are slidably connected to the side of the two partitions 405 adjacent to each other. The left and right sides of the connecting plate 309 are slidably connected to the left and right ends of the inner side of the through groove. The lower limit plate 313 and the upper limit plate 314 are provided with puncture holes inside. When the output shaft of the first motor 305 is started, it drives the active pulley 306 to rotate, which in turn drives the outer belt 307 to rotate, causing the driven pulley 304 to rotate. This, in turn, causes the connecting rod 303 to rotate, which in turn drives the rotating shaft 301 and the driven pulley 304 to rotate together. At the same time as the driven pulley 304 rotates, the round tube 308 rotates along with the U-shaped rod 302, causing the upper end of the connecting plate 309 to move up and down while rotating with the U-shaped rod 302. This causes the lower sliding plate 310 to slide up and down along the inner side of the inner shell 2, so that the needle head 311 at the lower end of the sliding plate 310 continuously passes through the piercing holes inside the lower limit plate 313 and the upper limit plate 314, piercing the aluminum silicate fiber blanket between the lower limit plate 313 and the upper limit plate 314.

[0028] The outer shell 1 is equipped with cleaning mechanisms at both its inner and outer ends. The cleaning mechanism includes a high-pressure blower 401 installed on the left side of the outer shell 1. The outlet end of the high-pressure blower 401 is fixedly connected to an outlet pipe 402. The right end of the outlet pipe 402 is fixedly connected to an outlet hopper 403. The upper right side of the inner shell 2 is fixedly connected to a connecting frame 404. The front and rear ends of the upper inner side of the inner shell 2 are fixedly connected to partitions 405. Ventilation ports are provided at the left end of the inner shell 2 to the right of the outlet hopper 403, the right end of the inner shell 2 to the left of the connecting frame 404, and the right end of the outer shell 1 to the right of the connecting frame 404. An outlet frame 501 is fixed to the ventilation port on the right side of the outer shell 1, and the ventilation port is located above the upper limit plate 314. The partitions 405 are located at the front and rear ends of the upper limit plate 314 and the sliding plate 310. During the needle punching process, by starting the high-pressure blower 401, a high-pressure airflow is generated and enters the air outlet pipe 402. Then, it enters the upper limit plate 314 through the air outlet hopper 403. When the needle head 311 is lifted, the airflow blows the fibers attached to the surface of the needle head 311 off and blows them together with the airflow into the connecting frame 404 at the right end. Then, it is discharged through the air outlet frame 501 at the right end. In this way, the fibers attached to the outside of the needle head 311 are removed at the same time during the puncturing of the aluminum silicate fiber blanket, so as to avoid affecting the puncturing of the aluminum silicate fiber blanket.

[0029] Cooperate Figure 4 and Figure 5An anti-clogging unit is provided at the right end of the outer casing 1. The anti-clogging unit includes an air outlet frame 501 fixedly connected to the middle position of the right side of the outer casing 1. A filter screen 502 is installed on the inner right end of the air outlet frame 501. A fixing plate 503 is fixedly connected to the inner right end of the air outlet frame 501. A first bearing 504 is installed at the middle position inside the fixing plate 503. A first round rod 505 is fixedly connected to the inner side of the first bearing 504. A fan blade 506 is fixedly connected to the outer rear end of the first round rod 505. A driving bevel gear 507 is fixedly connected to the rear end of the first round rod 505. A second bearing 508 is installed on the right side of the front end of the air outlet frame 501. A second rotating rod 509 is fixedly connected to the inner side of the second bearing 508. A driven bevel gear 510 is fixedly connected to the outer rear end of the second rotating rod 509. The driving bevel gear 507 meshes with the driven bevel gear 510. A drive gear 511 is fixedly connected to the outer front end of the second rotating rod 509, and the drive gear 511 meshes with the driven gear 513. A third bearing 512 is installed at the front end of the air outlet frame 501 to the right of the second bearing 508. A reciprocating screw 516 is installed inside the third bearing 512, and a driven gear 513 is fixedly connected to the outer front end of the reciprocating screw 516. A sliding shuttle 514 is installed at the outer end of the reciprocating screw 516, and a scraper 515 is fixedly connected to the outer end of the sliding shuttle 514. The right side of the scraper 515 is slidably connected to the left side of the filter screen 502. When the airflow carrying fibers is blown into the air outlet frame 501 from the left end and then filtered and discharged through the filter screen 502 at the right end, the airflow will blow the fan blades 506 to rotate, causing the first round rod 505 and the driving bevel gear 507 to rotate, causing the driven bevel gear 510 to rotate, which in turn causes the second rotating rod 509 to rotate. This causes the driving gear 511 and the driven gear 513 to rotate relative to each other, driving the reciprocating screw 516 to rotate. Consequently, the sliding shuttle 514 and scraper 515 at the outer end of the reciprocating screw 516 move back and forth, while sliding along the left side of the filter screen 502. This pushes the fibers filtered and retained on the left side of the filter screen 502 towards the front and rear ends of the left side of the filter screen 502, preventing the continuous accumulation of fibers on the left side of the filter screen 502 from causing blockage and ensuring the continuous and effective operation of fiber filtration.

[0030] Working principle: During the piercing of the aluminosilicate fiber blanket, the processed aluminosilicate fiber blanket is conveyed by the relatively rotating transmission roller 6 to the space between the lower limit plate 313 and the upper limit plate 314 in the inner shell 2. At the same time, the first motor 305 is turned on, and its output shaft rotates, driving the drive pulley 306 to rotate, which in turn drives the outer belt 307 to rotate, causing the driven pulley 304 to rotate. This, in turn, causes the connecting rod 303 to rotate, driving the rotating shaft 301 and the driven pulley 304 to rotate together. As the pulley 304 rotates, the round tube 308 rotates together with the U-shaped rod 302, causing the upper end of the connecting plate 309 to move up and down while rotating with the U-shaped rod 302. This causes the lower sliding plate 310 to slide up and down along the inner side of the inner shell 2, so that the needle head 311 at the lower end of the sliding plate 310 continuously passes through the piercing holes inside the lower limit plate 313 and the upper limit plate 314, piercing and reinforcing the aluminum silicate fiber blanket passing between the lower limit plate 313 and the upper limit plate 314.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
