Description

Technical Field

[0001] This invention belongs to the field of carding machine technology, specifically relating to a roller module of a pneumatic transfer carding machine. Background Technology

[0002] The cylinder's function is to improve fiber separation, straightness, and parallelism, eliminate forward hooks in cotton fibers, thereby enhancing yarn luster and spinnability for subsequent processes. It also removes impurities and defects, improving yarn quality in multiple ways. During cotton lint handling, the cylinder's rotation speed is typically higher than that of the rollers. During lint handling, cotton lint is attracted to the cylinder surface due to friction and moves with its rotation. When the cotton lint reaches the outer edge of the cylinder, centrifugal force throws it off the surface. Excessive cylinder rotation speed can lead to over-carding of the cotton lint, causing fiber breakage or damage, thus affecting product quality.

[0003] Therefore, a roller module for a pneumatic transfer carding machine is proposed to avoid excessive carding of cotton fibers, which could cause fiber breakage or damage. At the same time, it is also necessary to avoid the problem that cotton fibers are not easily removed from the cylinder due to excessively low cylinder speed, causing cotton fibers to accumulate on the cylinder, resulting in poor carding effect and incomplete removal of impurities and defects in the cotton fibers. Summary of the Invention

[0004] To address the above problems, the present invention aims to provide a roller module for a pneumatic transfer carding machine, which solves the problems of excessive carding of cotton lint when transferring material from the cylinder to the roller in existing carding machines, causing fiber breakage or damage, and cotton lint accumulating on the cylinder, resulting in poor carding effect and incomplete removal of impurities and defects in the cotton lint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a roller module of a pneumatic transfer carding machine, comprising a pneumatic transfer component that can blow cotton lint off the cylinder by high-pressure airflow to facilitate the removal of cotton lint and ensure carding effect, and a negative pressure lint-receiving mechanism that can effectively remove impurities and defects from the cotton lint. The pneumatic transfer component consists of a positive pressure fan and an air duct disposed below the positive pressure fan. The port of the air duct below the positive pressure fan is inclined toward the axis of the cylinder. The negative pressure lint-receiving mechanism is disposed directly below the pneumatic transfer component and the cylinder.

[0006] The pneumatic transfer assembly is installed in the frame. A cotton feeding conveyor belt is installed at the front end of the frame. A front upper and lower roller assembly is installed at the rear of the cotton feeding conveyor belt. A cotton opening roller and an airflow assembly are sequentially installed at the rear of the front upper and lower roller assembly. A rear upper and lower roller assembly is installed at the rear of the airflow assembly. A cotton opening roller is installed at the rear of the rear upper and lower roller assembly. A cylinder is installed at the rear of the cotton opening roller. A licker-in roller is installed above the cylinder. A cotton pressing roller is installed above the rear of the negative pressure cotton receiving mechanism. A retaining plate is installed below the rear of the negative pressure cotton receiving mechanism.

[0007] The beneficial effects of the present invention are as follows: the high-speed airflow in the air pressure transfer component can be blown obliquely toward the surface of the cylinder, so that the cotton lint floats off the cylinder and is easy to throw off the cylinder, avoiding the accumulation of cotton lint on the cylinder, which would lead to poor combing effect. Impurities in the cotton can be collected by the negative pressure receiving mechanism, and defects in the cotton lint can also be effectively stretched and removed.

[0008] In order to effectively blow up the lint on the cylinder, so that the lint can be easily removed from the cylinder;

[0009] As a further improvement to the above technical solution: the air duct in the air pressure transfer assembly is composed of a frame and two enclosures installed on the inner wall of the frame. The second enclosure is located between the cylinder and the first enclosure. The bottom end of the first enclosure is bent into a guide plate, which is inclined toward the axis of the cylinder.

[0010] The beneficial effects of this improvement are as follows: when the high-speed airflow blown out by the positive pressure blower flows downward through the air duct, part of the downward airflow is blocked by the first guide plate. Under the guidance of the first guide plate, it is obliquely blown towards the surface of the cylinder, thereby lifting the cotton fibers on the cylinder and making it easier for the cotton fibers to detach from the rotating cylinder.

[0011] In order to effectively blow up the lint on the cylinder, so that the lint can be easily removed from the cylinder;

[0012] As a further improvement to the above technical solution: the bottom end of the second enclosure plate is bent into a second guide plate, which is inclined toward the direction of the first guide plate.

[0013] The beneficial effects of this improvement are as follows: when the high-speed airflow blown out by the positive pressure blower flows downward through the air duct, part of the downward airflow is blocked by the second guide plate. Under the guidance of the second guide plate, it is blown to the first guide plate, and then continues to be blown obliquely towards the surface of the cylinder, thereby lifting the cotton fibers on the cylinder and making it easier for the cotton fibers to detach from the rotating cylinder.

[0014] In order to effectively catch the cotton lint that comes off the cylinder and effectively remove impurities and defects from the cotton lint;

[0015] As a further improvement to the above technical solution: the negative pressure flocking mechanism includes a conveyor belt assembly and a negative pressure fan and filter assembly. The conveyor belt of the conveyor belt assembly is uniformly provided with a sieve structure, and the air inlet of the negative pressure fan and filter assembly is located on the inner side of the conveyor belt assembly.

[0016] The beneficial effects of this improvement are as follows: cotton lint is adsorbed onto the surface of the conveyor belt assembly under the action of pressure difference. Under the action of negative pressure in the screen holes, impurities in the cotton lint are effectively removed. Furthermore, due to the speed difference between the cylinder and the conveyor belt assembly, defects in the cotton lint can be effectively stretched and eliminated.

[0017] In order to effectively collect and exhaust the airflow delivered by the positive pressure fan;

[0018] As a further improvement to the above technical solution: an air outlet is provided on the side wall of the frame between the negative pressure down-feeding mechanism and the air pressure transfer component.

[0019] The beneficial effects of this improvement are: the air outlet can balance the internal and external air pressure of the frame, prevent excessive airflow from the positive pressure fan from causing the lint inside the frame to overflow, and also prevent negative pressure from forming inside the frame.

[0020] To effectively prevent lint from detaching from the cylinder from directly entering the air outlet;

[0021] As a further improvement to the above technical solution: a lower baffle is installed on the frame between the air outlet and the cylinder.

[0022] The beneficial effects of this improvement are: the lower baffle acts as a barrier, preventing lint from detaching from the cylinder from directly entering the air outlet.

[0023] In order to effectively prevent the cotton fibers from being scratched and damaged by the lower baffle during the transfer process;

[0024] As a further improvement to the above technical solution: the lower baffle is formed by bending an upper blocking section, a rear blocking section, and a bending section as a whole. A connecting section is provided on one side of the rear blocking section. The rear blocking section is an angle iron structure bent into shape from the rear side of the upper blocking section. The bending section is a flat plate structure bent into shape from the rear side of the rear blocking section, and the connection between the bending section and the rear blocking section is formed with a rounded corner structure.

[0025] The beneficial effects of this improvement are as follows: during the process of the conveyor belt assembly transferring cotton lint, the hanging cotton lint is tilted away from the cylinder by the conveyor belt assembly. The rear shielding section can effectively avoid the cotton lint tilting backward, while the bending section can prevent the cotton lint from being scratched by sharp corners.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1:

[0033] like Figure 1As shown in Figure 3: A roller module of a pneumatic transfer carding machine includes a pneumatic transfer component 100 that can blow cotton lint off the cylinder 10 with high-pressure airflow to facilitate lint removal and ensure carding effect, and a negative pressure lint-receiving mechanism 5 that can effectively remove impurities and defects from the cotton lint. The pneumatic transfer component 100 consists of a positive pressure fan 13 and an air duct located below the positive pressure fan 13. The port of the air duct below the positive pressure fan 13 is inclined towards the axis of the cylinder 10. The negative pressure lint-receiving mechanism 5 is located directly below the pneumatic transfer component 100 and the cylinder 10. The pneumatic transfer component 100 is installed in a frame 1. A cotton inlet conveyor belt 2 is installed at the front end of the frame 1. A front upper and lower roller group 3 is installed at the rear side of the cotton inlet conveyor belt 2. A cotton opening roller 4 and an airflow assembly 6 are sequentially installed on the rear side of the lower roller group 3. A rear upper and lower roller group 7 is located behind the airflow assembly 6, and a cotton opening roller 9 is located behind the rear upper and lower roller group 7. A cylinder 10 is installed behind the cotton opening roller 9, and a licker-in roller 11 is installed on the upper side of the cylinder 10. A cotton pressing roller 12 is installed above and behind the negative pressure cotton collecting mechanism 5, and a surrounding plate 15 is installed below and behind the negative pressure cotton collecting mechanism 5. The high-speed airflow in the air pressure transfer assembly 100 can be obliquely blown onto the surface of the cylinder 10, causing the cotton fibers to float up from the cylinder 10 and be easily thrown off, preventing cotton fibers from accumulating on the cylinder and causing poor combing effect. Impurities in the cotton can be collected by the negative pressure of the negative pressure cotton collecting mechanism 5, and defects in the cotton fibers are also... The airflow in the pneumatic transfer assembly 100 is composed of a frame 1 and two side panels 15 and 16 installed on the inner wall of the frame 1. The second side panel 16 is located between the cylinder 10 and the first side panel 15. The bottom end of the first side panel 15 is bent into a guide plate 151, which is inclined towards the axis of the cylinder 10. When the high-speed airflow blown by the positive pressure fan 13 flows downward through the airflow duct, part of the downward airflow is blocked by the guide plate 151. Under the guidance of the guide plate 151, the airflow is obliquely blown onto the surface of the cylinder 10, thereby lifting the lint on the cylinder 10 and making it easier for the lint to detach from the rotating cylinder 10. The bottom end of the second side panel 16 is bent into a guide plate 161. The second guide plate 161 is inclined towards the first guide plate 151. When the high-speed airflow blown out by the positive pressure fan 13 flows downward through the air duct, part of the downward airflow is blocked by the second guide plate 161. Under the guidance of the second guide plate 161, the airflow is blown towards the first guide plate 151, and then continues to be blown obliquely towards the surface of the cylinder 10, thereby lifting the cotton fibers on the cylinder 10, so that the cotton fibers can be easily removed from the rotating cylinder 10. The negative pressure lint collection mechanism 5 includes a conveyor belt assembly 51 and a negative pressure fan and filter assembly 52. ​​The conveyor belt assembly 51 has a screen hole structure evenly opened on the conveyor belt. The air inlet of the negative pressure fan and filter assembly 52 is located on the inner side of the conveyor belt assembly 51. Under the action of pressure difference, the cotton fibers are adsorbed onto the surface of the conveyor belt assembly 51.Under the negative pressure in the sieve holes, impurities in the cotton lint are effectively removed. Furthermore, due to the speed difference between the cylinder 10 and the conveyor belt assembly 51, defects in the cotton lint can be effectively stretched and eliminated. An air outlet 17 is provided on the side wall of the frame 1 between the negative pressure lint collection mechanism 5 and the air pressure transfer assembly 100. The air outlet 17 balances the internal and external air pressure of the frame 1, preventing excessive airflow from the positive pressure fan 13 from causing lint to overflow from inside the frame 1, and also preventing the formation of negative pressure inside the frame 1. A lower baffle 18 is installed on the frame 1 between the air outlet 17 and the cylinder 10. The lower baffle 18 acts as a barrier, preventing cotton lint detached from the cylinder 10 from directly entering the air outlet 17. The 18th section is formed by bending an upper shielding section 181, a rear shielding section 182, and a bending section 183 as a whole. A connecting section 184 is provided on one side of the rear shielding section 182. The rear shielding section 182 is an angle iron structure bent to the rear of the upper shielding section 181. The bending section 183 is a flat structure bent to the rear of the rear shielding section 182, and the connection between the bending section 183 and the rear shielding section 182 has a rounded corner structure. During the process of the conveyor belt assembly 51 transferring cotton lint, the hanging cotton lint is driven by the conveyor belt assembly 51 to tilt away from the cylinder 10. The rear shielding section 182 can effectively avoid the backward-tilting cotton lint, while the bending section 183 can prevent the cotton lint from being scratched by sharp corners.

[0034] The working principle of this technical solution is as follows: The cotton to be combed is placed on the cotton feeding conveyor belt 2. Through the cooperation of the cotton feeding conveyor belt 2 and the front upper and lower roller group 3, the cotton is fed into the opening roller 4 and the airflow assembly 6 for opening. Then, the cotton is fed into the space between the opening roller 9, the licker-in roller 11 and the cylinder 10 through the rear upper and lower roller group 7. Under the cooperation of the opening roller 9, the licker-in roller 11 and the cylinder 10, the opened cotton is combed, so that the cotton has a relatively uniform thickness and has lateral and longitudinal tensile strength. Then, driven by the rotating cylinder 10, the cotton fibers move to the air duct formed between the frame 1, the second partition plate 16 and the first partition plate 15. The airflow blown by the positive pressure blower 13 is obliquely blown onto the surface of the cylinder 10 under the guidance of the first guide plate 151 and the second guide plate 161, so that the cotton fibers float from the cylinder 10, thus making the cotton fibers more easily combed. Under the centrifugal force of the cylinder 10, the cotton fibers fall onto the conveyor belt assembly 51, preventing the accumulation of cotton fibers on the cylinder and thus avoiding poor combing effect. Some of the gas can enter the negative pressure fan and filter assembly 52 through the screen holes on the conveyor belt of the conveyor belt assembly 51 and be extracted to the outside. The other part of the gas can be directly discharged to the outside through the air outlet 17. When the cotton fibers fall onto the surface of the conveyor belt of the conveyor belt assembly 51, the impurities in the cotton fall into the dust cage 53 through the screen holes. The short fibers in the horizontal and vertical directions of the cotton are stretched vertically under the action of negative pressure. In addition, the impurities in the cotton fibers are extracted and removed through the screen holes on the conveyor belt of the conveyor belt assembly 51. Moreover, since the speed difference between the conveyor belt assembly 51 and the cylinder 10 is maintained, the defects in the cotton fibers can also be effectively removed by the stretching of the conveyor belt assembly 51. Finally, the cotton fibers are guided by the pressing roller 12 to the collecting roller 14 and rolled into cotton wadding.
