Description

TECHNICAL FIELD

[0001] The present application relates to the field of carding machines, in particular to a fixed flat bar framework of a carding machine. BACKGROUND

[0002] The main function of the movable flat bar of the carding machine is to card, remove impurities, mix and remove most of the neps, impurities and short fibers in the opening process. The distance between the fixed flat bar of the carding machine and the carding machine cylinder clothing is very important for the quality of the carding. The function of the fixed flat bar in the carding process is to pre-card the opened fibers. The fixed flat bar is mainly arranged on the inlet side and outlet side of the cylinder, and a few are arranged below the cylinder. The core function is to "pretreat" and "re-card" the fibers, and to improve the carding quality and impurity removal efficiency of the auxiliary main carding area. The distance between the fixed flat bar and the carding machine cylinder clothing forms an effective carding space. A stable carding space is very important for the stability of the carding quality and the carding effect. Only the appropriate distance can make the fibers get the necessary but not excessive carding.

[0003] The fixed flat bar is usually made of metal. During work, the bottom of the fixed flat bar will deform due to the heat generated by friction with the cylinder and the increase of the ambient temperature. Especially the middle part of the flat bar, which is closer to the machine frame than the two ends of the flat bar, the heat is easily conducted and dissipated through the machine frame. The middle part of the flat bar is the main area of fiber carding, and the contact with the cylinder and the fiber is more sufficient. The heat accumulation is more, the temperature is higher than the two ends, and the thermal expansion is naturally larger. Therefore, the deformation of the middle part of the flat bar due to heat is larger than that of the two ends of the flat bar. The deformation of the middle part of the flat bar due to heat will cause sinking, and the gap between the needle teeth on the flat bar and the cylinder will be reduced, resulting in excessive carding, which will directly cause fiber damage and reduce the quality of the cotton web. Even the needle teeth on the flat bar and the needle teeth on the cylinder will collide, damaging the carding machine, or the deformation of the flat bar will cause arching, resulting in insufficient carding in the middle part and easy to leave neps and impurities. Whether the flat bar arches or sinks will seriously affect the carding quality. Therefore, we need a fixed flat bar structure that can reduce the impact of the deformation of the flat bar due to heat on the carding quality. SUMMARY

[0031] The keel member 1 includes a cover plate outer frame 11 arranged at the top of the bottom plate member 2, as shown in Figure 2 , the cross section of the cover plate outer frame 11 is a reversed "U" shape, the bottom plate member 2 and the movable needle member 3 are both accommodated inside the cover plate outer frame 11, and a heat dissipation window 12 is opened at the side of the cover plate outer frame, the heat dissipation window 12 is opened at both sides of the cover plate outer frame 11, and the opening of the heat dissipation window 12 at both sides of the cover plate outer frame 11 is beneficial to ventilation and heat dissipation.

[0032] Further, the bottom plate member 2 includes a needle plate 21 arranged at the bottom of the cover plate outer frame 11 and a cross beam 22 arranged at the top of the needle plate 21, as shown in Figure 2As shown, the needle plate 21 is fixedly connected with the bottom of the cover plate outer frame 11, the crossbeam 22 is arranged at both ends of the bottom plate component 2, and the top of the bottom plate component 2 is fixedly connected with the top of the cover plate outer frame 11 through the crossbeam 22, and the crossbeam 22 provides rigid support for the bottom plate component 2.

[0033] Further, as shown in the drawings, Figure 4 As shown, the bottom of the needle plate 21 is provided with fixed needle teeth 23 at both ends, the needle teeth at both ends of the needle plate 21 are fixedly connected with the bottom of the needle plate 21, and the bottom of the needle plate 21 is provided with a tooth outlet groove 24 in the middle, and the tooth outlet groove 24 arranged in the middle of the needle plate 21 is for the movable needle component 3 to be able to extend from the middle of the needle plate 21 to participate in combing.

[0034] Further, the movable needle component 3 comprises a support rod structure 31 arranged on the top of the needle plate 21, as shown in the drawings, Figure 3 As shown, the bottom of the support rod structure 31 is fixedly connected with the needle plate 21, the side surface of the support rod structure 31 is provided with a cotton comb needle body 32, the top of the cotton comb needle body 32 is provided with a heat dissipation plate structure 33, the cotton comb needle body 32 is movably connected with the support rod structure 31, the cotton comb needle body 32 is movably connected with the heat dissipation plate structure 33, the heat dissipation plate structure 33 has a plurality of blocks, the bottom of each block of the heat dissipation plate structure 33 is provided with a plurality of cotton comb needle bodies 32, and the heat dissipation plate structure 33 is matched with the heat dissipation window 12. During the cotton combing process, the bottom plate component 2 is rubbed with the fiber to be combed to generate heat, the heat is conducted to the heat dissipation plate structure 33, external air can enter the inside of the cover plate outer frame 11 from the heat dissipation window 12, pass through the middle of the plurality of heat dissipation plate structures 33, and take away part of the heat on the heat dissipation plate structure 33, thereby taking away part of the heat inside the cover plate outer frame 11, and delaying the deformation process of the bottom plate component 2.

[0035] During use, after the entire keel component 1 is installed on the cotton inlet side or the cotton outlet side of the cylinder through the mounting plate 4, the cotton and other fibers pass through the gap between the cylinder and the needle plate 21 and are combed by the needle teeth at the bottom of the needle plate 21. During the combing process, the friction between the fiber and the needle plate 21 generates heat, which is conducted to the heat dissipation plate structure 33. External air can enter the inside of the cover plate outer frame 11 from the heat dissipation window 12, pass through the middle of the plurality of heat dissipation plate structures 33, and take away part of the heat on the heat dissipation plate structure 33, thereby taking away part of the heat inside the cover plate outer frame 11, and delaying the deformation process of the bottom plate component 2.

[0036] During the heat accumulation process, the needle plate 21 will be deformed due to heat, especially the middle part of the needle plate 21, which may be arched or even sunken due to heat. The movable needle component 3 can flexibly adjust the angle according to the arching or sinking of the needle plate 21, as shown in the drawings, Figure 8As shown in the figure, the arrow direction is the advancing direction of the fiber, and the angle a is the rake angle of the needle tooth. When the rake angle increases, the penetration ability of the needle tooth becomes stronger, and the carding effect is enhanced. When the rake angle decreases, the penetration ability of the needle tooth becomes smaller, and the carding effect is weakened. When the middle part of the needle plate 21 is arched, the gap between the bottom of the needle plate 21 and the cylinder increases, and the carding effect of the needle plate 21 is weakened due to the deformation of the needle plate 21. At this time, the movable needle member 3 will increase the rake angle of the needle tooth to enhance the carding effect of the needle tooth. When the middle part of the needle plate 21 sinks, the gap between the bottom of the needle plate 21 and the cylinder decreases, which is easy to cause the needle tooth between the bottom of the needle plate 21 and the cylinder to collide. At this time, the movable needle member 3 will reduce the rake angle of the needle tooth to lift the needle tooth upward to prevent the collision between the needle teeth.

[0037] Embodiment 2, refer to Figures 1-9 , which is the second embodiment of the present application, different from the previous embodiment, this embodiment introduces the process of adjusting the angle of the needle tooth by the movable needle member 3, as shown in Figure 6 , the support rod structure 31 includes a support rod 311 arranged on the top of the needle plate 21, and the top of the support rod 311 is provided with a sliding frame 312, and the bottom of the support rod 311 is fixedly connected with the needle plate 21, as shown in Figure 7 , the sliding frame 312 is a waist hole shape, and there is a parallel sliding rail in the middle of the sliding frame 312.

[0038] Further, as shown in Figure 6 , the cotton carding needle body 32 includes a tooth tip part 321 extending out of the needle plate 21 from the tooth slot 24 and a tooth root part 322 arranged on the top of the tooth tip part 321, and the tooth root part 322 is inside the cover plate outer frame 11, and the side surface of the tooth root part 322 is provided with a middle shaft 323, and the top of the tooth root part 322 is provided with an abutting rod 324, and the abutting rod 324 is arranged inside the sliding frame 312, and the abutting rod 324 can slide in the extension direction of the sliding frame 312, and the heat dissipation plate structure 33 includes a heat dissipation fin plate 331, and the top of the heat dissipation fin plate 331 is connected with the top of the cover plate outer frame 11, and the bottom of the heat dissipation fin plate 331 is connected with the needle plate 21, and the side surface of the heat dissipation fin plate 331 is provided with a reinforcing rib 333, and the reinforcing rib 333 increases the rigidity of the heat dissipation fin plate 331, and the bottom of the heat dissipation fin plate 331 is provided with a support hole 332, and the middle shaft 323 is arranged inside the support hole 332, and the middle shaft 323 can rotate inside the support hole 332, and the heat dissipation fin plate 331 is connected with the needle plate 21, which can conduct the heat on the needle plate 21 out, and the air coming from the heat dissipation window 12 can take away the heat on the surface of the heat dissipation fin plate 331, and the heat dissipation fin plate 331 increases the heat dissipation area of the needle plate 21, which can effectively take away part of the heat on the needle plate 21 and reduce the thermal deformation of the needle plate 21.

[0039] Use process: when the fixed cover plate runs on the carding machine for a period of time, heat will accumulate on the needle plate 21, the needle plate 21 will be deformed by heat, especially the middle part of the needle plate 21 will be severely deformed, as shown in Figure 8 When the middle part of the needle plate 21 arches up, the needle plate 21 will drive the support rod 311 to move up, the support rod 311 moving up will drive the sliding frame 312 to move up, the sliding frame 312 will exert an upward force on the abutting rod 324 of the tooth root part 322, since the pivot of the middle part of the tooth root part 322 is limited by the heat dissipation fin 331 and cannot move up, the carding needle body 32 will rotate clockwise around the pivot, so the angle α in the figure becomes larger, that is, the rake angle of the carding needle tooth becomes larger, the carding effect of the needle tooth becomes stronger, the carding needle body 32 also inserts more fibers, reducing the impact of the arching of the needle plate 21, ensuring the carding quality;

[0040] When the middle part of the needle plate 21 sinks, the needle plate 21 will drive the support rod 311 to descend, the support rod 311 descending will drive the sliding frame 312 to descend, the sliding frame 312 will exert a downward force on the abutting rod 324 of the tooth root part 322, so the carding needle body 32 will rotate counterclockwise around the pivot, so the angle α in the figure becomes smaller, that is, the rake angle of the carding needle tooth becomes smaller, preventing the fibers from being excessively carded, at the same time, the vertical size of the carding needle body 32 extending out of the tooth groove 24 will be reduced, preventing the carding needle body 32 on the needle plate 21 from colliding with the teeth on the cylinder, protecting the carding machine.
