Description

Technical Field

[0001] This utility model relates to the technical field of cotton yarn processing equipment, and in particular to a dust removal system used in a dust removal and carding device. Background Technology

[0002] In cotton yarn processing, the impurity removal and carding device is a key piece of equipment for improving cotton yarn quality. Its core function is to remove impurities such as dust, short fibers, seed fragments, and fiber clumps from cotton fibers through negative pressure adsorption. Existing impurity removal and carding devices mostly use ordinary motors to drive fan blades to generate negative pressure. To ensure the airflow velocity, high power operation is often required, resulting in high energy consumption. Furthermore, the air inlet of the suction pipe is easily clogged by large impurities (such as fiber clumps and hard seed fragments), affecting the impurity removal efficiency and even damaging components such as the fan blades. Simultaneously, the filter plates in the suction system are easily clogged by impurities after long-term use, requiring manual cleaning and production interruptions. The collected impurities also need to be disposed of after machine shutdown, making continuous impurity removal impossible and failing to meet the production requirements of cotton yarn processing for low energy consumption, continuous operation, and high stability.

[0003] Therefore, this utility model proposes a dust removal system for a dust removal carding device to solve the above problems.

Bevel gears (first type) are fixedly sleeved on the bottom end of the rotating shaft on the left side and on the main shaft. Bevel gears (second type) are fixedly sleeved on the rotating shaft on the right side and on the hollow shaft. Bevel gears (first type) and (second type) on the rotating shaft mesh with bevel gears (second type) on the hollow shaft and bevel gears (first type) on the rotating shaft, respectively. The top ends of both rotating shafts extend outside the suction pipe and are fixedly sleeved with pulleys. The same belt is connected to the two pulleys for transmission.

[0011] Preferably, two spherical protective shells are rotatably mounted on the main shaft, and the two rotating shafts are rotatably connected to the corresponding protective shells respectively, with bevel gear one and bevel gear two, which are in a meshing state, located in the same protective shell.

[0012] Preferably, the dust removal assembly includes a material guide turntable, a servo motor, and multiple material guide baffles.

[0018] This invention uses a variable frequency motor to drive the main shaft and fan blades to generate negative pressure suction, drawing impurities from the cotton yarn into the suction pipe. Simultaneously, the rotating and fixed blade holders on the main shaft work together to shear and break the sucked-in impurities, preventing large pieces from clogging the pipe. As the broken impurities pass through the filter plate under the action of airflow, the deceleration component enables the main shaft to drive the hollow shaft and cleaning brush to rotate at a low speed, thereby continuously cleaning the surface of the filter plate and preventing the filter holes from clogging and affecting the suction efficiency. The impurities eventually fall into the collection box, and then the servo motor in the dust removal component drives the guide turntable and guide baffle to push the impurities to the discharge port for discharge, realizing continuous and non-stop impurity removal operation.

[0019] By using a reduced-diameter design for the air inlet of the suction pipe, the Venturi effect can be utilized to increase the air intake speed even when the variable frequency motor is operating at low power, thereby reducing energy consumption to some extent. The filter plate is made of stainless steel and features a gradually changing filter hole diameter design, which effectively intercepts impurities while ensuring smooth ventilation. In addition, the grille prevents dust from being stirred up again inside the collection box. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-6 A dust removal system for a dust removal carding device includes a suction pipe 1, a variable frequency motor 21, a fan blade 22, a main shaft 2, and a collection box 6.

[0030] The air inlet of the suction pipe 1 is designed with a narrow diameter, and the air outlet of the suction pipe 1 is fixedly installed with a mesh cover 11 by bolts. A filter plate 12 is fixedly installed inside the suction pipe 1, and a main shaft 2 is rotatably installed on the filter plate 12. A variable frequency motor 21 is fixedly installed inside the suction pipe 1, and the output shaft of the variable frequency motor 21 is connected to the main shaft 2 through a coupling. The fan blade 22 is fixedly installed on the main shaft 2 and located on the side of the filter plate 12 near the air inlet. The filter plate 12 is made of stainless steel, and several circular filter holes are evenly distributed on the surface of the filter plate 12. The diameter of the filter holes gradually decreases from the air inlet side to the air outlet side, which can effectively intercept larger impurities, ensure air circulation efficiency, and reduce the resistance to the rotation of the fan blade 22.

[0031] A hollow shaft 41 is rotatably mounted on the outer side of the main shaft 2. Two cleaning brushes 4 that are in active contact with the filter plate 12 are radially fixed on the hollow shaft 41. The cleaning brushes 4 can clean the filter plate 12 when the hollow shaft 41 rotates, thereby preventing debris from adhering to the filter plate 12 and affecting the ventilation efficiency of the filter plate 12.

[0032] Two parallel rotating shafts 5 are rotatably mounted on the suction pipe 1. A bevel gear 51 is fixedly sleeved on the bottom of the left rotating shaft 5 and on the main shaft 2. A bevel gear 52 is fixedly sleeved on the right rotating shaft 5 and the hollow shaft 41. The bevel gear 51 and bevel gear 52 on the rotating shaft 5 mesh with the bevel gear 52 on the hollow shaft 41 and the bevel gear 51 on the rotating shaft 5, respectively. The top ends of the two rotating shafts 5 extend to the outside of the suction pipe 1 and are fixedly sleeved with pulleys 53. The two pulleys 53 are connected to the same belt 54, which can transmit power to the hollow shaft 41 and achieve a deceleration effect, thereby avoiding unnecessary wear caused by the cleaning brush 4 moving too fast.

[0033] A fixed blade holder 3 is fixedly installed on the inner wall of the air inlet of the suction pipe 1, with the axis of the suction pipe 1 as the center. A rotating blade holder 31 is fixedly installed on the main shaft 2. The distance between the rotating blade holder 31 and the fixed blade holder 3 is 0.05-0.2mm. When cotton yarn enters the suction pipe 1, the relative high-speed rotation of the rotating blade holder 31 and the fixed blade holder 3 can cut and break the fiber clumps, hard debris and other impurities mixed in, so as to prevent large pieces of debris from clogging the suction pipe 1 or damaging subsequent components.

[0034] The collection box 6 is fixedly installed on the suction pipe 1 and kept in a connected state. The collection box 6 has an arc-shaped discharge port. The collection box 6 is cylindrical. A servo motor 62 is fixedly installed at the bottom of the collection box 6. The output shaft of the servo motor 62 extends into the collection box 6 and is fixedly installed on a guide turntable 61. The top side of the guide turntable 61 is set with the middle higher and the surrounding area lower. Multiple guide baffles 63 are fixedly installed on the top side of the guide turntable 61, which are arranged radially based on the output shaft of the servo motor 62. The multiple guide baffles 63 are in movable sealing contact with the inner wall of the collection box 6, which can collect the debris discharged downward from the suction pipe 1 and can also realize ash discharge operation without stopping the machine.

[0035] In this embodiment, in order to provide shielding protection for bevel gear 1 51 and bevel gear 2 52 and prevent debris from interfering with their normal transmission, two spherical protective shells 55 are rotatably installed on the main shaft 2. The two rotating shafts 5 are rotatably connected to the corresponding protective shells 55, and the bevel gear 1 51 and bevel gear 2 52, which are in a meshing state, are located in the same protective shell 55.

[0036] In this embodiment, in order to provide stable support for the variable frequency motor 21 and the main shaft 2, thereby ensuring their stable operation, a shock-absorbing bracket 201 and a support frame are fixedly installed inside the air suction pipe 1. The main shaft 2 is rotatably mounted on the shock-absorbing bracket 201 and the support frame. The shock-absorbing bracket 201 is located on the leeward side of the filter plate 12, and the variable frequency motor 21 is fixedly installed on the side of the shock-absorbing bracket 201 away from the filter plate 12.

[0037] In this embodiment, in order to effectively reduce the risk of dust that has entered the collection box 6 being excessively stirred up and re-entering the suction pipe 1, and at the same time to guide the airflow and ensure that impurities and dust can fall smoothly into the bottom of the collection box 6, an arc-shaped grid plate 601 is fixedly installed at the connection port between the suction pipe 1 and the collection box 6.

[0038] In order to significantly reduce the noise generated by the variable frequency motor 21 during operation and thus improve the working environment, the outer shell of the variable frequency motor 21 is wrapped with sound insulation cotton.

[0039] In addition, an external controller is used to control the variable frequency motor 21 and the servo motor 62 separately. The variable frequency motor 21 can rotate in reverse when needed to compensate for the possibility that debris from the cleaning brush 4 may not be completely cleaned and may clog the filter holes. If necessary, the mesh cover 11 can be removed and the staff can use tools to clean the leeward side of the filter plate 12 through the shock absorption bracket 201.

[0040] Since the content protected by this application does not involve improvements to software, circuits, and methods, all circuits, electronic components, and module mechanisms that are required but not mentioned in detail are based on existing technologies that can be fully implemented by those skilled in the art, and therefore will not be elaborated further.

[0041] Working principle: When in use, first connect the air inlet of the suction pipe 1 to the core area of ​​the impurity generation of the impurity removal and carding device used for cotton yarn processing, and then start the variable frequency motor 21. Its output shaft drives the main shaft 2 to rotate through the coupling. The fan blades 22 on the main shaft 2 rotate accordingly and form a negative pressure airflow in the suction pipe 1. Since the air inlet of the suction pipe 1 is set with a reduced diameter, the venturi effect can be used to ensure that the speed of airflow drawn at the air inlet position of the suction pipe 1 can still be guaranteed when the variable frequency motor 21 is running at low power.

[0042] During the processing and conveying of cotton yarn, impurities such as fiber clumps and dust particles embedded on its surface and inside are drawn into the narrowed air inlet of the suction pipe 1 under negative pressure. At this time, the main shaft 2 drives the rotating blade holder 31 to rotate synchronously. The 0.05-0.2mm gap between the rotating blade holder 31 and the fixed blade holder 3 forms a shearing zone. The high-speed rotating blades shear and break up the large impurities and fiber clumps drawn in, preventing them from clogging the suction pipe 1 or damaging subsequent components. The broken impurities continue to move towards the filter plate 12 with the airflow. When passing through the filter plate 12, the stainless steel filter plate 12 intercepts the impurities through the filter holes with gradually changing diameters. Larger impurities are blocked on the side of the filter plate 12 near the air inlet, while the air passes through the filter holes and is discharged from the air outlet. The mesh cover 11 can effectively prevent foreign objects from entering the interior of the suction pipe 1.

[0043] While the main shaft 2 rotates, it drives the right rotating shaft 5 to rotate via bevel gear 1 51. The pulley 53 at the top of the right rotating shaft 5 drives the left rotating shaft 5 to rotate synchronously via belt 54. The left rotating shaft 5 then drives the hollow shaft 41 to rotate via bevel gear 2 52. The diameter of bevel gear 1 51 is smaller than that of bevel gear 2 52, thereby achieving a speed reduction effect. This makes the rotational speed of the hollow shaft 41 lower than that of the main shaft 2. The cleaning brush 4 on the hollow shaft 41 rotates at a lower speed in contact with the filter plate 12 and continuously cleans the impurities adhering to the surface of the filter plate 12, preventing the filter holes from being blocked and affecting the ventilation efficiency. The impurities that are cleaned down and those intercepted by the filter plate 12 fall into the collection box 6 through the connection between the suction pipe 1 and the collection box 6 under the action of gravity and part of the airflow. At the same time, the arc-shaped grid plate 601 guides the airflow, preventing impurities from being excessively stirred up in the collection box 6 and re-entering the suction pipe 1.

[0044] Impurities falling into the collection box 6 fall onto the guide turntable 61. The servo motor 62 drives the guide turntable 61 to rotate slowly. The structure of the guide turntable 61, which is high in the middle and low around the edges, together with multiple guide baffles 63 that are in contact with the inner wall of the collection box 6, can push the impurities towards the inner wall of the collection box 6. When the guide baffles 63 rotate to the discharge port position, the impurities are discharged from the discharge port under the push of the guide baffles 63, thus enabling continuous ash removal operation without stopping the machine.

[0045] Throughout the process, the shock-absorbing bracket 201 provides stable support for the variable frequency motor 21 and the main shaft 2 and reduces vibration. The protective shell 55 provides sealing protection for the bevel gear set to prevent impurities from interfering with gear transmission. If the filter plate 12 is slightly clogged, the variable frequency motor 21 can be reversed by adjusting the external controller while the impurity removal and carding device is stopped. The reverse airflow is used to assist the cleaning brush 4 in cleaning the filter holes. If the clogging is severe, the mesh cover 11 can be removed and the staff can use tools to clean the leeward side of the filter plate 12 through the shock-absorbing bracket 201.

[0046] The above provides a detailed description of the impurity suction system for a carding and cleaning device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
