Description

Technical Field

[0001] This utility model relates to the field of carding technology, and in particular to a cleaning device for the movable cover plate of a carding machine and a carding machine. Background Technology

[0002] Carding machines are equipment in the textile process. During the carding process, the moving cover plate accumulates a large amount of short fibers, impurities, and dust on its surface. To ensure carding quality and stable equipment operation, the moving cover plate must be effectively cleaned. In existing technology, fiber impurities are stripped off and thrown into the cover plate cleaning suction channel; finally, the negative pressure generated by the main unit's dust filter assembly connected to one end of the cover plate cleaning suction channel draws the fiber impurities away through this suction channel.

[0003] However, the aforementioned prior art has a drawback, see [link to previous text] Figure 1 Because the cardboard cleaning channel 01 typically only has a suction port at one end, the airflow needs to travel a long distance from the other end (i.e., the "far end") to the near end. This unilateral suction mode results in extremely uneven distribution of wind speed and volume within the channel. At the end furthest from the main unit's dust filter components, wind speed and volume decrease, creating a low-pressure or weak airflow zone. Insufficient suction in this area prevents the timely and thorough removal of fiber impurities thrown in by the high-speed rollers. This leads to the gradual accumulation of fly ash and dust at the far end of the channel, reducing the cleaning effect of the movable cardboard and affecting the carding quality.

[0004] Therefore, how to provide a cleaning device for the movable cover plate of a carding machine to promptly remove fiber impurities thrown in by the high-speed roller is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cleaning device for the movable cover plate of a carding machine, which effectively solves the problem of the inability to timely remove fiber impurities thrown in by the high-speed roller.

[0006] Another objective of this invention is to provide a carding machine that includes the aforementioned carding machine movable cover cleaning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A carding machine movable cover cleaning device includes a low-speed roller, a high-speed roller, and a cover cleaning suction channel arranged sequentially along the fiber impurity transfer direction. The low-speed roller is used to peel short fibers and impurities from the movable cover, and the high-speed roller is used to peel off the fiber impurities on the low-speed roller and throw them into the cover cleaning suction channel. The first end of the cover cleaning suction channel is connected to the main dust filter assembly, and the second end of the cover cleaning suction channel is connected to a suction connection assembly. The cross-sectional area of ​​the inlet end of the suction connection assembly is smaller than the opening area of ​​the second end of the cover cleaning suction channel. The suction connection assembly is connected to the main dust filter assembly through a rear suction pipe, thereby forming a double-sided synchronous suction structure at the first and second ends of the cover cleaning suction channel.

[0009] Preferably, the suction connection assembly is installed and fixed through a connection hole opened on the side of the main unit housing away from the main unit dust filter assembly.

[0010] Preferably, the rear air intake pipe is a metal pipe or a rigid plastic pipe.

[0011] Preferably, the connection between the suction connection assembly and the rear suction pipe is a sealed connection.

[0012] Preferably, the surface of the low-speed roller is provided with a needle cloth or serrated structure.

[0013] Preferably, the high-speed roller is a metal needle roller or a toothed roller.

[0014] Preferably, the suction connection assembly is a component formed by bonding a horizontally arranged circular suction pipe and a vertically arranged suction channel together. Its inlet end is connected to the second end opening of the cover plate cleaning suction channel, and its outlet end is connected to the rear suction pipe.

[0015] Preferably, the suction connection assembly is a rigid polyvinyl chloride component, and the inner wall of the suction connection assembly is a smooth surface.

[0016] Preferably, the inlet end cross-sectional shape of the suction connection assembly is adapted to the second end opening of the cover plate cleaning suction channel.

[0017] A carding machine equipped with a carding machine movable cover cleaning device as described above.

[0018] Compared with the above-mentioned background technology, the carding machine movable cover cleaning device provided by this utility model has a high-speed roller and a low-speed roller arranged adjacent to each other. It is used to effectively peel off the fiber impurities attached to the surface of the low-speed roller and throw them into the inlet area of ​​the cover cleaning suction channel located below it. The cover cleaning suction channel is a hollow channel structure, and its first end (the side near the main dust filter assembly) is in fluid communication with the main dust filter assembly to perform the main airflow suction.

[0019] At the second end (the far end in the diagram, i.e. the side originally away from the main unit's dust filter assembly) opposite to the first end of the cover plate cleaning suction channel, a suction connection component is connected. The cross-sectional area of ​​the inlet end of the suction connection component is set to be smaller than the opening area of ​​the second end of the cover plate cleaning suction channel. The suction connection component is in fluid communication with the main unit's dust filter assembly through a rear suction pipe.

[0020] Therefore, the main unit's dust filtration assembly can simultaneously draw air from both the first and second ends of the cover plate cleaning suction channel, forming a highly efficient and balanced dual-sided synchronous suction structure. This improves the airflow distribution inside the cover plate cleaning suction channel, especially at the original low-volume far end, ensuring that the fibers and dust thrown in by the high-speed roller can be quickly and thoroughly removed, effectively avoiding the problem of dust accumulation at the far end caused by unilateral suction.

[0028] 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.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See Figures 2-3 This application provides a cleaning device for the movable cover plate of a carding machine, comprising a low-speed roller 1, a high-speed roller 2, and a cover plate cleaning suction channel 3 arranged sequentially along the fiber impurity transfer direction. The low-speed roller 1 is used to peel short fibers and impurities from the movable cover plate, and the high-speed roller 2 is used to peel off the fiber impurities on the low-speed roller 1 and throw them into the cover plate cleaning suction channel 3. The first end of the cover plate cleaning suction channel 3 is connected to the main dust filter assembly, and the second end of the cover plate cleaning suction channel 3 is connected to a suction connection assembly 4. The cross-sectional area of ​​the inlet end of the suction connection assembly 4 is smaller than the opening area of ​​the second end of the cover plate cleaning suction channel 3. The suction connection assembly 4 is connected to the main dust filter assembly through a rear suction pipe 5, thereby forming a double-sided synchronous suction structure at the first and second ends of the cover plate cleaning suction channel 3.

[0031] Specifically, the low-speed roller 1 is configured to interact with the moving movable cover plate, using the needle cloth or serrated structure on its surface to peel short fibers and impurities from the movable cover plate. The high-speed roller 2 is arranged adjacent to the low-speed roller 1, and its surface linear velocity is higher than that of the low-speed roller 1. It is used to effectively peel off the fiber impurities attached to the surface of the low-speed roller 1 and throw them into the inlet area of ​​the cover plate cleaning suction channel 3 located below it. The cover plate cleaning suction channel 3 is a hollow channel structure, and its first end (the side closer to the original host dust filter assembly) is in fluid communication with the host dust filter assembly for the main airflow suction.

[0032] At the second end (the far end in the diagram, i.e. the side originally away from the main dust filter assembly) opposite to the first end of the cover plate cleaning suction channel 3, a suction connection component 4 is connected. The cross-sectional area of ​​the inlet end of the suction connection component 4 is set to be smaller than the opening area of ​​the second end of the cover plate cleaning suction channel 3. The suction connection component 4 is in fluid communication with the main dust filter assembly through a rear suction pipe 5.

[0033] Therefore, the main dust filter assembly can simultaneously draw from the first and second ends of the cover plate cleaning suction channel 3, forming a highly efficient and balanced dual-sided synchronous suction structure. This improves the airflow distribution inside the cover plate cleaning suction channel 3, especially at the original low-volume far end, ensuring that the fibers and dust thrown in by the high-speed roller 2 can be quickly and thoroughly removed, effectively avoiding the problem of dust accumulation at the far end caused by unilateral suction.

[0034] Based on the above embodiments, the suction connection component 4 is installed and fixed through the connection hole opened on the side of the main unit housing away from the main unit dust filter component.

[0035] Specifically, the suction connection assembly 4 is installed and fixed through a connection hole on the side of the main housing away from the main dust filter assembly. The connection hole is located on the housing wall at the corresponding position of the second end of the cover plate cleaning suction channel 3, and its shape is adapted to the inlet end of the suction connection assembly 4. The suction connection assembly 4 is fixed to the connection hole by welding, bolting, or quick-release buckles. The installation is stable and easy to maintain and disassemble later. This makes full use of the original equipment space and achieves remote pressure boosting and suction without changing the main structure, which is suitable for upgrading and optimizing existing carding machines.

[0036] Based on the above embodiments, the rear suction pipe 5 is a metal pipe or a rigid plastic pipe, and the suction connection assembly 4 is connected to the rear suction pipe 5 in a sealed manner.

[0037] In other words, the rear air intake pipe 5 is a metal pipe or a rigid plastic pipe, which has the beneficial effects of structural stability, low airflow resistance, and resistance to deformation.

[0038] The suction connection assembly 4 and the rear suction pipe 5 are connected in a sealed manner. This can be achieved through methods such as flange with sealing gasket, clamp fastening, threaded connection or bonding, to ensure that there is no air leakage at the connection, thus ensuring the negative pressure stability and suction efficiency of the remote suction system. The sealed connection structure effectively prevents external air from seeping in or internal dust-laden airflow from leaking, which helps to maintain the air volume balance of simultaneous suction on both sides and further improves the ability to remove flying dust and debris.

[0039] Based on the above embodiments, the surface of the low-speed roller 1 is provided with a needle cloth or serrated structure, and the high-speed roller 2 is a metal needle roller or serrated roller.

[0040] Specifically, the low-speed roller 1 has a needle-like or serrated structure on its surface. The needle-like structure consists of a base and densely arranged needles, or the serrated structure is distributed in a continuous serrated pattern. It can effectively embed into the gaps between the needle surfaces of the movable cover plate, grabbing residual short fibers, lint, and fine impurities to achieve preliminary cleaning. The low-speed roller 1 rotates at a low speed, runs smoothly, and avoids damage to the movable cover plate. The high-speed roller 2 is a metal needle roller or serrated roller, with high-strength metal needles or precision-machined serrations on its surface, providing good wear resistance and peeling ability. The high-speed roller 2 rotates at a much higher speed than the low-speed roller 1. Through the centrifugal force generated by the high-speed rotation and the shearing action between the needles / teeth, the fibers and impurities attached to the surface of the low-speed roller 1 are forcefully peeled off and thrown into the cover plate cleaning suction channel 3, ensuring that the low-speed roller remains clean and improving the efficiency of repeated cleaning.

[0041] Based on the above embodiments, the suction connection component 4 is a component formed by bonding a horizontally arranged circular suction pipe and a vertically arranged suction channel. Its inlet end is connected to the second end opening of the cover plate cleaning suction channel 3, and its outlet end is connected to the rear suction pipe 5. The suction connection component 4 is a rigid polyvinyl chloride part, and the inner wall of the suction connection component 4 is a smooth surface. The cross-sectional shape of the inlet end of the suction connection component 4 is adapted to the second end opening of the cover plate cleaning suction channel 3.

[0042] Specifically, the inlet end of the suction connection component 4 is connected to the second end opening of the cover plate cleaning suction channel 3, and the outlet end is connected to the rear suction pipe 5, which is used to guide the airflow away from the main dust filter component to the main dust filter component to achieve remote auxiliary suction.

[0043] The bending angle of the suction connection component 4 is designed to adapt to the spatial layout of the equipment and achieve a reasonable direction of airflow. The suction connection component 4 is made of rigid polyvinyl chloride and has a smooth inner wall, which effectively reduces the resistance of airflow when passing through the bend, reduces eddies and energy loss, and ensures the continuity and stability of the suction speed.

[0044] The inlet end cross-sectional shape of the suction connection component 4 is adapted to the second end opening of the cover plate cleaning suction channel 3, and is usually circular to ensure a sealed connection with the end face of the suction channel; the outlet end can be designed as circular or teardrop-shaped according to the interface form of the rear suction pipe 5, so as to facilitate a reliable connection with the rear suction pipe 5.

[0045] This application also provides a carding machine equipped with the carding machine movable cover cleaning device as described above. The movable cover cleaning device is used to continuously remove short fibers, fly ash, and dust that fall off the movable cover during the carding process. By integrating the above-mentioned cleaning device with a dual-sided synchronous suction structure, the carding machine effectively solves the problems of insufficient far-end air volume, fly ash accumulation, and lint entanglement on the cleaning roller caused by traditional single-sided suction, thereby improving the cleaning efficiency of the movable cover and the overall stability of the machine operation.

[0046] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0047] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
