Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery and equipment, in particular to a dust removal mechanism and method for a carding machine. Background Art

[0002] Carding machines are key equipment in the textile production process. Their primary function is to comb pre-processed cotton fibers into a uniform web for subsequent processing. During carding, the cotton fibers can become contaminated with a large amount of impurities, such as cottonseed hulls, linters, and dust. These impurities not only affect the quality of the web and textiles, but can also cause wear and tear on carding machine components, shortening the equipment's lifespan.

[0003] The existing carding machine dust removal equipment has the following technical problems:

[0004] (1) At present, the dust removal technology of carding machines mainly relies on dust suction devices and static or unidirectional rotating cleaning parts. Although traditional dust suction devices can remove some impurities, it is difficult to effectively remove impurities that are tightly attached to the surface of cotton fibers or entangled in the fibers due to the limited vacuum pressure and lack of targeted pretreatment. For example, when processing cotton fibers containing a large amount of cottonseed shell debris and short fibers, the dust suction device can only remove part of the dust on the surface. Cottonseed shell debris often remains due to its large weight and close entanglement with the fibers. Short fibers are also easily reattached to the fibers under airflow disturbance, resulting in incomplete dust removal.

[0005] (2) Existing carding machines rely on a single dust collection device or a simple mechanical separation structure for impurity separation. When the dust collection device is processing large impurities, large particles (such as cottonseed shell fragments, broken leaves, etc.) are heavy and irregular in size, which easily form blockages in the dust collection pipe, causing the equipment to stop frequently for cleaning, greatly affecting production efficiency. For example, when processing raw cotton with a high impurity content, the dust collection pipe may need to be cleaned every 2-3 hours, which not only increases the labor intensity of workers, but also reduces the effective working time of the carding machine. At the same time, in order to ensure that large impurities can also be sucked in, the dust collection fan often needs to run at high power, resulting in energy waste and high operating costs.

[0006] Therefore, we propose a carding machine dust removal mechanism and method to solve the above problems. Summary of the Invention

[0014] Preferably, the box body is also provided with an accelerated discharge component for accelerating the rapid discharge of fine dust and impurities in the discharge pipe, the accelerated discharge component includes a support plate fixed on one side of the rocker arm, the top of the support plate is fixed with a rocker arm 2, the top of the rocker arm 2 is fixed with a knocking ball 2, one side of the inner wall of the box body is fixed with a mounting plate, the inner surface of the mounting plate is slidably connected with a moving rod, the top of the moving rod is fixed with a pressure plate, one side of the pressure plate is fixed with an inclined plate 2, the outer surface of the knocking ball 2 is in contact and extruded with the inclined surface of the inclined plate 2, the bottom end of the moving rod is fixed with a moving plate, the bottom of the moving plate is fixed with an acceleration rod, the bottom end of the acceleration rod is fixed with a material passing column, the moving rod is provided with a spring 2, the top of the spring 2 is fixed to the bottom of the pressure plate, and the bottom end of the spring 2 is fixed to the top of the support plate.

[0015] Preferably, a door is rotatably connected to one side of the box body through a hinge, and two bases are fixed to the bottom of the box body.

[0016] The present invention also discloses a dust removal method for a carding machine, which specifically comprises the following steps:

[0017] Step 1: Install the dust removal mechanism in the cotton web area between the cylinder and the doffer of the carding machine, start motor 1, and motor 1 drives the driving rod and the cam to rotate. The protruding end of the cam intermittently contacts and squeezes the roller, driving the cleaning roller to move back and forth intermittently up and down. When the driving rod rotates, it drives the second bevel gear and the first bevel gear to rotate, and the first bevel gear drives the vertical rod to rotate. Due to the setting of the limit plate on the vertical rod, the third bevel gear is driven to rotate synchronously. At the same time, the third bevel gear slides up and down along the outer surface of the vertical rod during the reciprocating up and down movement of the H-shaped frame. The third bevel gear drives the fourth bevel gear to rotate, and then drives the cleaning roller to rotate. The protrusion on the cleaning roller intermittently scrapes impurities on the cotton web;

[0018] Step 2: Start the vacuum cleaner, which uses multiple vacuum heads to draw impurities on the cleaning roller into the separation drum. Start the second motor, which drives the separation drum to rotate. Using centrifugal force, impurities with larger mass and volume are thrown out from the through-hole. Start the vacuum cleaner connected to the discharge pipe. Impurities with smaller mass and volume are sucked away from the center of the separation drum through the discharge pipe by the vacuum cleaner. Large impurities are thrown out and fall to the inner wall of the ring plate and are blocked. They then fall into the ring groove for collection. Start the fan to discharge the large impurities in the ring groove from the discharge pipe.

[0019] Step 3. When the small impurities carried by the large impurities are attracted to the inner wall of the ring plate due to electrostatic force, the motor 1 will synchronously drive the fifth bevel gear and the sixth bevel gear to rotate during the startup process, thereby driving the ratchet to rotate, and then the ratchet drives the U-shaped claw to swing left and right, thereby driving the pendulum rod 1 and the knocking ball 1 to knock the inclined plate 1 and the ring plate. The vibration of the ring plate helps the small impurities fall down. When the pendulum rod 1 swings, it will synchronously drive the pendulum rod 2 and the knocking ball 2 to swing. During the process of the knocking ball 2 intermittently knocking the inclined plate 2, the moving rod drives the acceleration rod and the material passing column to move downward, and the material passing column drives the small impurities to accelerate into the discharge pipe for discharge.

[0020] Beneficial effects

[0021] The present invention provides a dust removal mechanism and method for a carding machine. Compared with the prior art, it has the following beneficial effects:

[0022] (1) By setting up an intermittent lifting and scraping mechanism and utilizing the reciprocating movement of the cleaning roller up and down, the cleaning roller intermittently impacts the cotton web. Through the dynamic impact force in the vertical direction and the periodic disturbance of the fiber layer, the interlocking structure of impurities and fibers on the cotton web can be effectively destroyed, and the deep and entangled impurities can be loosened. This solves the problems of insufficient negative pressure in traditional dust collection devices and single force of static cleaning components, significantly improves dust removal efficiency, reduces the risk of fiber damage, and achieves deep and efficient dust removal.

[0023] (2) Through the setting of the impurity separation mechanism, large impurities (such as cottonseed shell fragments) are thrown out of the separation cylinder by centrifugal force. After contacting the inner wall of the ring plate, they slide into the ring groove and are blown out by the fan. Light dust is sucked away by the vacuum cleaner from the center of the separation cylinder through the discharge pipe, which greatly reduces the probability of pipeline blockage and thus improves production efficiency.

[0024] (3) Through the setting of the intermittent knocking vibration component, the intermittent lifting and scraping mechanism drives the knocking ball to knock the ring plate intermittently when working, which can effectively break the adsorption effect of electrostatic force on dust and impurities, so that the dust and impurities on the inner wall of the ring plate are shaken off, avoiding dust accumulation on the inner wall of the ring plate affecting the operation of the equipment.

[0025] (4) By accelerating the setting of the discharge component, when the intermittent knocking vibration component is working, it can synchronously drive the knocking ball 2 to knock the inclined plate 2, thereby driving the acceleration rod and the material passing column to move up and down, thereby accelerating the discharge of fine dust impurities in the separation cylinder through the discharge pipe, thereby improving the dust removal efficiency.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The present invention provides three technical solutions, including the following embodiments:

[0038] Example 1

[0039] See also Figure 1-Figure 7 A carding machine dust removal mechanism comprises a box body 1, an intermittent lifting and scraping mechanism 2 is provided on the top of the box body 1, and the intermittent lifting and scraping mechanism 2 is used for intermittently scraping impurities on the cotton net in the carding machine;

[0040] The intermittent lifting and scraping mechanism 2 includes a bottom plate 21 fixed to the top of the box body 1, and two fixed seats 22 are fixed on the top of the bottom plate 21. The fixed seat 22 is "T"-shaped, and a driving rod 23 is rotatably connected between the opposite sides of the two fixed seats 22. A cam 24 is fixed on the driving rod 23, and an H-shaped frame 25 is arranged between the upper parts of the two fixed seats 22. A vertical rod 26 is fixed on the top of the fixed seat 22. The top ends of the two vertical rods 26 extend to the inside of the H-shaped frame 25, and the H-shaped frame 25 slides on the vertical rod 26, specifically sliding in the vertical direction. A cleaning roller 27 is rotatably connected between the opposite sides of the H-shaped frame 25. When the cleaning roller 27 rotates, it contacts the bottom of the cotton web between the cylinder and the doffer of the cotton carding machine. The cleaning roller 27 is set to roll and clean impurities and dust on the cotton web. A plurality of protrusions 28 are fixed on the cleaning roller 27. The setting of the protrusion 28 can better penetrate into the interior of the cotton web and remove cottonseed shells. The cleaning roller 27 is moved upwards to the bottom of the cotton net, and the cleaning roller 27 is moved downwards to the bottom of the cotton net, so that the cleaning roller 27 is moved upwards to the bottom of the cotton net, and the protrusion 28 penetrates into the cotton net. When the non-protruding end of the cam 24 contacts the roller 210, the cleaning roller 27 is separated from the cotton net, and the impurities and dust fall down, which is convenient for dust collection. A square plate 211 is fixed to one side of the H-shaped frame 25 and one side of the fixed seat 22, and a spring 212 is fixed between the opposite sides of the two square plates 211. The spring 212 is set to quickly reset the cleaning roller 27. The box body 1 is provided with a driving component 3 that drives the cleaning roller 27 to rotate and move up and down intermittently.

[0041] The driving assembly 3 includes a horizontal plate 31 fixed to the fixed seat 22 and one side of the H-shaped frame 25. The top of the lower horizontal plate 31 is rotatably connected to the vertical rod 32. The outer surface of the vertical rod 32 is fixed with a first bevel gear 33. One end of the driving rod 23 is fixed with a second bevel gear 34. The first bevel gear 33 meshes with the second bevel gear 34. The third bevel gear 35 is rotatably connected to the upper horizontal plate 31. The fourth bevel gear 36 is fixed to the rotating shaft end of the cleaning roller 27. The third bevel gear 35 meshes with the fourth bevel gear 36. Limiting plates 37 are fixed on both sides of the vertical rod 32. The vertical rod 32 slides inside the third bevel gear 35. The third bevel gear 35 and the horizontal plate 31 are provided with a space for contact with the limiting plate 3 7. The setting of the limiting groove with matching size of the limiting plate 37 and the limiting groove can ensure that the third bevel gear 35 can be driven to rotate synchronously when the vertical rod 32 rotates, and can also allow the third bevel gear 35 to slide up and down along the vertical rod 32. The other end of the driving rod 23 is fixed with a pulley 1 38, and one side of the box body 1 is rotatably connected to a pulley 2 39. The pulley 1 38 and the pulley 2 39 are connected by a belt 310. An L-shaped plate 311 is fixed to one side of the box body 1, and a motor 1 312 is fixed to one side of the L-shaped plate 311. The motor 1 312 is controlled by an external switch and is electrically connected to an external power supply. The output end of the motor 1 312 is fixed to one side of the pulley 2 39.

[0042] By setting up the intermittent lifting and scraping mechanism 2 and utilizing the up and down reciprocating movement of the cleaning roller 27, it intermittently makes impact contact with the cotton web. Through the dynamic impact force in the vertical direction and the periodic disturbance of the fiber layer, it can effectively destroy the interlocking structure of impurities and fibers on the cotton web, loosen deep and entangled impurities, and solve the problems of insufficient negative pressure in traditional dust collection devices and single force of static cleaning components, significantly improve dust removal efficiency, reduce the risk of fiber damage, and achieve deep and efficient dust removal.

[0043] The box body 1 is also provided with a dust collection component 4 for vacuuming the impurities scraped off by the intermittent lifting and scraping mechanism 2. The dust collection component 4 includes a curved pipe 41 connected to the top of the box body 1. One end of the curved pipe 41 is connected to a horizontal pipe 42. The top of the horizontal pipe 42 is connected to multiple dust collection heads 43. The dust collection heads 43 are used to absorb impurities and dust adhered to the cleaning roller 27. The bottom end of the curved pipe 41 extends to the interior of the box body 1. A vacuum cleaner 44 is installed at the bottom end of the curved pipe 41. The vacuum cleaner 44 is controlled by an external switch and is electrically connected to an external power supply. After the vacuum cleaner 44 is started, the dust and impurities on the cotton net of the carding machine are sucked into the separation cylinder 51 using the dust collection head 43.

[0044] The interior of the box body 1 is provided with an impurity separation mechanism 5, which includes a separation cylinder 51 arranged inside the box body 1. A through hole 52 is opened on the separation cylinder 51. When the separation cylinder 51 rotates, centrifugal force is used to throw out large-mass impurities through the through hole 52, while small-mass impurities remain in the separation cylinder 51 and are discharged through a discharge pipe 53. The bottom of the separation cylinder 51 is connected with a discharge pipe 53, and the discharge pipe 53 is connected with an external vacuum cleaner. When the external vacuum cleaner is started, the fine impurities and dust in the separation cylinder 51 can be sucked out. The bottom end of the discharge pipe 53 extends to the bottom of the box body 1, and the outer surface of the discharge pipe 53 is rotatably connected to the inner surface of the box body 1. A gear 1 54 is fixed on the discharge pipe 53, and a gear 2 55 is rotatably connected to the bottom wall of the box body 1. The gear 2 55 is meshed with the gear 1 54. A motor 2 56 is fixed to the bottom of the box body 1, and the motor 2 56 is controlled by an external switch, and The outer ring 58 is provided with a plurality of holes 57 for receiving the impurities, and the holes 58 are provided with a plurality of holes 59 for receiving the impurities.

[0045] By setting up the impurity separation mechanism 5, centrifugal force is used to throw large impurities (such as cottonseed shell fragments) out of the separation cylinder. After contacting the inner wall of the ring plate 57, they slide into the ring groove 58 and are blown out by the fan 511. Light dust is sucked away by the vacuum cleaner from the center of the separation cylinder 51 through the discharge pipe 53, which greatly reduces the probability of pipeline blockage and thus improves production efficiency.

[0046] A door 8 is rotatably connected to one side of the box body 1 through a hinge, and two bases 9 are fixed to the bottom of the box body 1.

[0047] Example 2

[0048] Based on Example 1, see Figure 8 and Figure 9As shown, the interior of the box body 1 is provided with an intermittent percussion vibration material assembly 6 for knocking the ring plate 57 and making it vibrate. The intermittent percussion vibration material assembly 6 includes a cross bar 61 fixed to one side of the pulley 39, and a side plate 62 is fixed to one side of the inner wall of the box body 1. One end of the cross bar 61 is fixed to a fifth bevel gear 63, and one side of the side plate 62 is rotatably connected to a rotating rod 64. One end of the rotating rod 64 is fixed to a sixth bevel gear 65. The fifth bevel gear 63 meshes with the sixth bevel gear 65, and the other end of the rotating rod 64 is fixed to a ratchet 66. One side of the side plate 62 is rotatably connected to a U-shaped claw 68 through a rotating column 67. The setting of the U-shaped claw 68, in conjunction with the rotation of the ratchet teeth of the ratchet 66, can drive the U-shaped claw The two claw ends of the claw 68 intermittently contact the ratchet teeth, allowing the U-shaped claw 68 to swing, and the two claw ends of the U-shaped claw 68 are engaged with the ratchet teeth of the ratchet wheel 66. A fixed column 69 is fixed on the rotating column 67, and a rocker arm 610 is fixed on the top of the fixed column 69. A knocking ball 611 is fixed on the top of the rocker arm 610. An L-shaped frame 612 is fixed on one side of the ring plate 57, and an inclined plate 613 is fixed on the top of the L-shaped frame 612. The outer surface of the knocking ball 611 is in contact and squeezed with the inclined surface of the inclined plate 613. After the knocking ball 611 knocks the inclined plate 613, the inclined plate 613 transmits the vibration to the ring plate 57, and then uses the vibration to shake off the impurities adsorbed on the ring plate 57.

[0049] By setting up the intermittent knocking vibration component 6, the intermittent lifting and scraping mechanism 6 can synchronously drive the knocking ball 611 to intermittently knock the ring plate 57 when working, which can effectively break the adsorption effect of electrostatic force on dust and impurities, so that the dust and impurities on the inner wall of the ring plate 57 are shaken off, avoiding dust accumulation on the inner wall of the ring plate 57 affecting the operation of the equipment.

[0050] The box body 1 is also provided with an accelerated discharge component 7 for quickly discharging fine dust and impurities in the discharge pipe 53. The accelerated discharge component 7 includes a support plate 71 fixed to one side of the rocker arm 1 610, a rocker arm 2 72 is fixed on the top of the support plate 71, and a knocking ball 2 73 is fixed on the top of the rocker arm 2 72. A mounting plate 74 is fixed on one side of the inner wall of the box body 1, and a moving rod 75 is slidably connected to the inner surface of the mounting plate 74. A pressure plate 76 is fixed on the top of the moving rod 75, and an inclined plate 2 77 is fixed on one side of the pressure plate 76. The outer surface of the knocking ball 2 73 contacts and squeezes the inclined surface of the inclined plate 2 77, and a moving plate 78 is fixed to the bottom of the moving plate 78. An accelerating rod 79 is fixed to the bottom of the accelerating rod 79. A material passing column 710 is fixed to the bottom of the accelerating rod 79.

[0051] By accelerating the setting of the discharge component 7, when the intermittent knocking vibration component 6 is working, it can synchronously drive the knocking ball 2 73 to knock the inclined plate 2 77, thereby driving the acceleration rod 79 and the material passing column 710 to accelerate up and down, thereby accelerating the discharge of fine dust impurities in the separation cylinder 51 through the discharge pipe 53, thereby improving the dust removal efficiency.

[0052] Example 3

[0053] Based on Example 2, see Figures 1-9 As shown, the present invention also discloses a dust removal method for a carding machine, which specifically includes the following steps:

[0054] Step 1, install the dust removal mechanism in the cotton web area between the cylinder and the doffer of the cotton carding machine, start the motor 312, the motor 312 drives the driving rod 23 and the cam 24 to rotate, and the protruding end of the cam 24 intermittently contacts and squeezes the roller 210, driving the cleaning roller 27 to move back and forth intermittently. When the driving rod 23 rotates, it drives the second bevel gear 34 and the first bevel gear 33 to rotate, and the first bevel gear 33 drives the vertical rod 32 to rotate. Due to the setting of the limit plate 37 on the vertical rod 32, the third bevel gear 35 is driven to rotate synchronously. At the same time, the third bevel gear 35 slides up and down along the outer surface of the vertical rod 32 during the reciprocating up and down movement of the H-shaped frame 25. The third bevel gear 35 drives the fourth bevel gear 36 to rotate, thereby driving the cleaning roller 27 to rotate, and the protrusion 28 on the cleaning roller 27 intermittently scrapes impurities on the cotton web;

[0055] Step 2: Start the vacuum cleaner 44. The vacuum cleaner 44 draws impurities on the cleaning roller 27 into the separation drum 51 through multiple dust collector heads 43. Start the second motor 56. The second motor 56 drives the separation drum 51 to rotate, and uses centrifugal force to throw out impurities with larger mass and volume from the through hole 52. Start the vacuum cleaner connected to the discharge pipe 53 on the outside. Impurities with smaller mass and volume are sucked away from the center of the separation drum through the discharge pipe 53 by the vacuum cleaner. After being thrown out, large impurities fall to the inner wall of the ring plate 57 and are blocked. Then they fall into the annular groove 58 for collection. Start the fan 511 to discharge the large impurities in the annular groove 58 from the discharge pipe 59.

[0056] Step 3. When the small impurities carried by the large impurities are thrown out and adsorbed on the inner wall of the ring plate 57 due to electrostatic force, the motor 1 312 synchronously drives the fifth bevel gear 63 and the sixth bevel gear 65 to rotate during the startup process, and then drives the ratchet 66 to rotate, and then the ratchet 66 drives the U-shaped claw 68 to swing left and right, and then drives the swing rod 1 610 and the knocking ball 1 611 to knock the inclined plate 1 613 and the ring plate 57. The vibration of the ring plate 57 helps the small impurities fall. When the swing rod 1 610 swings, it synchronously drives the swing rod 2 72 and the knocking ball 2 73 to swing. In the process of the knocking ball 2 73 intermittently knocking the inclined plate 2 77, the moving rod 75 drives the acceleration rod 79 and the material passing column 710 to move downward, and the material passing column 710 drives the small impurities to accelerate into the discharge pipe 53 for discharge.

A method for removing dust from a carding machine, characterized in that: The specific steps include: Step 1, the dust removal mechanism is installed in the cotton web area between the cylinder and the doffer of the carding machine, and the motor 1 (312) is started. The motor 1 (312) drives the driving rod (23) and the cam (24) to rotate. The protruding end of the cam (24) intermittently contacts and squeezes the roller (210), driving the cleaning roller (27) to intermittently move back and forth. When the driving rod (23) rotates, the second bevel gear (34) and the first bevel gear (33) are driven to rotate. The first bevel gear (33) drives the vertical rod (32) to rotate. Due to the setting of the limit plate (37) on the vertical rod (32), the third bevel gear (35) is driven to rotate synchronously. At the same time, the third bevel gear (35) slides up and down along the outer surface of the vertical rod (32) during the reciprocating up and down movement of the H-shaped frame (25). The third bevel gear (35) drives the fourth bevel gear (36) to rotate, thereby driving the cleaning roller (27) to rotate. The protrusion (28) on the cleaning roller (27) intermittently scrapes impurities on the cotton web; Step 2: Start the vacuum cleaner (44). The vacuum cleaner (44) draws the impurities on the cleaning roller (27) into the separation drum (51) through the multiple dust collecting heads (43). Start the second motor (56). The second motor (56) drives the separation drum (51) to rotate. The centrifugal force is used to throw out the impurities with larger mass and volume from the through hole (52). Start the vacuum cleaner connected to the discharge pipe (53). The impurities with smaller mass and volume are sucked away from the center of the separation drum (51) through the discharge pipe (53). The large impurities are thrown out and fall on the inner wall of the ring plate (57) and are blocked. They fall into the ring groove (58) for collection. Start the fan (511) to discharge the large impurities in the ring groove (58) from the discharge pipe (59). Step 3: When the small impurities carried by the large impurities are attracted to the inner wall of the ring plate (57) due to the electrostatic force, the motor 1 (312) drives the fifth bevel gear (63) and the sixth bevel gear (65) to rotate synchronously during the startup process, thereby driving the ratchet (66) to rotate, and then the ratchet (66) drives the U-shaped claw (68) to swing left and right, thereby driving the swing rod 1 (610) and the knocking ball 1 (611) to knock the inclined plate 1 (613) and the ring plate (57). The vibration of the ring plate (57) assists the small impurities to fall. When the swing rod 1 (610) swings, it simultaneously drives the swing rod 2 (72) and the knocking ball 2 (73) to swing. During the process of the knocking ball 2 (73) intermittently knocking the inclined plate 2 (77), the moving rod (75) drives the acceleration rod (79) and the material column (710) to move downward, and the material column (710) drives the small impurities to accelerate into the discharge pipe (53) for discharge.
