Description

TECHNICAL FIELD

[0001] The utility model belongs to textile machinery technical field, especially a kind of new movable cover plate brush roller device and carding machine. BACKGROUND

[0002] Carding machine is composed of cotton feeding box component, cotton feeding roller component, licker-in component, cylinder component, movable cover plate component, movable cover plate cleaning component, doffer component, stripping roller component, condenser etc..Movable cover plate is responsible for the carding of cotton bundle, the movement direction of movable cover plate is opposite to the rotation direction of cylinder.Working time, movable cover plate takes out short hair, impurity, part fiber etc.in cotton bundle, these are collectively referred to as cover plate flower.The cover plate flower taken out is cleaned by movable cover plate cleaning device, so that the surface of movable cover plate needle tooth passing through movable cover plate cleaning device is kept clean, and continue to carry out the next carding work.

[0003] As Figure 1 As shown in the prior art related technology, movable cover plate cleaning device is mainly composed of big brush main transmission wheel 1, big brush roller 2, original high-speed cleaning roller 3, high-speed cleaning roller main transmission wheel 5, original dust removal knife 4, original suction passage 6 etc., big brush roller 2 and original high-speed cleaning roller 3 roll body are covered with metal elastic needle cloth.The transmission of big brush roller is driven by movable cover plate motor through reduction gear box, and the working speed of big brush roller 2 is 18r / min, and it rotates clockwise.The original high-speed cleaning roller is driven by original cleaning roller motor through belt transmission, and the working speed of original high-speed cleaning roller is 1400r / min, and it rotates counterclockwise.Working time, movable cover plate moves along the arrow direction straight line slowly (moving speed 100-300mm / min), big brush roller 2 rotates clockwise slowly, and the cover plate flower is stripped from the surface of movable cover plate 7, and the cover plate flower stripped is rotated with big brush roller 2, enters the minimum separation distance between big brush roller 2 and original high-speed cleaning roller 3 (the minimum separation distance value between the outer circle of needle tooth of big brush roller 2 and original high-speed cleaning roller 3 is-0.5--1.0mm, with slight intersection), original high-speed cleaning roller 3 rotates counterclockwise at high speed, and the cover plate flower on the surface of big brush roller 2 is quickly grabbed by the needle tooth of original high-speed cleaning roller 3, and then enters original suction passage 6 along the rear holding plate of original dust removal knife 4 under the action of centrifugal rate, and is sucked away by the suction device installed on one side.The original dust removal knife 4 is used to remove the residual cover plate flower on the surface of big brush roller 2 needle cloth, and keep the cleaning degree of the surface of big brush roller 2 needle cloth.The original high-speed cleaning roller 3 plays a major role when cleaning big brush 2, and the original dust removal knife plays an auxiliary role.

[0004] But the above structure has problems (disadvantages) in normal production process, which are described as follows:

[0005] 1.1 The problem of cleaning the movable cover plate. The surface of the large brush roller is covered with elastic wire cloth, the height of the elastic wire cloth is 18.5mm-19mm, and the elastic wire cloth of the large brush roller 2 slightly contacts the surface of the movable cover plate needle tooth during work. After a long time of continuous operation (usually after 3-5 months), the elastic wire cloth needle tip is worn due to friction (or the elastic wire cloth at the root of the large brush roller is deformed due to extrusion), the distance between the large brush roller 2 and the movable cover plate 7 becomes larger, and the cover plate flower on the surface of the movable cover plate needle tooth cannot be effectively cleaned, some uncleaned cover plate flowers enter the cylinder work again with the movable cover plate, which reduces the carding quality of the carding machine, thereby affecting the sliver quality of the carding machine.

[0006] 1.2 The large brush roller winding problem occurs frequently. During work, due to the slow speed of the large brush roller 2, the cover plate flowers peeled off from the surface of the movable cover plate enter the intersection position of the original high-speed cleaning roller 3, most of the cover plate flowers on the surface of the large brush roller 2 are cleaned by the original high-speed cleaning roller 3, but a small part of the cover plate flowers are deposited near the root of the needle cloth and cannot be cleaned by the original high-speed cleaning roller 3. Once a small amount of cover plate flowers are not cleaned, during continuous work, the uncleaned cover plate flowers will move towards the root of the needle tooth, and in the later stage, the phenomenon of accelerated accumulation will occur, thereby causing the large brush roller winding problem, which causes the large brush roller to be unable to work. After this situation occurs, the large brush roller elastic wire cloth needs to be replaced, or the large brush roller needs to be manually cleaned, but manual cleaning of the large brush roller can easily cause damage to the needle cloth of the large brush roller, and the installation of the carding machine will quickly cause the winding problem again.

[0007] 1.3 The winding phenomenon of the original high-speed cleaning roller. The original high-speed cleaning roller 3 peels off the cover plate flowers from the surface of the large brush roller 2, and under the action of the centrifugal rate, the peeled cover plate flowers are separated from the surface of the original high-speed cleaning roller 3. During this process, there is no other auxiliary stripping structure, once the cover plate flowers cannot be quickly separated from the surface of the original high-speed cleaning roller due to various reasons, the residual cover plate flowers will be extruded into the bottom of the needle tooth of the original high-speed cleaning roller 3 by the new cover plate flowers peeled off from the large brush roller 2, and after a long time of continuous operation, the problem of cover plate flower winding around the original high-speed cleaning roller occurs.

[0008] 1.4 Influence the brush roller elastic card clothing service life and safety problem. The distance between the large brush roller 2 and the original high-speed cleaning roller 3 is negative (the distance value is-0.5~ -1.0mm), and the needle tip of the large brush roller 2 is slightly contacted with the needle tip of the original high-speed cleaning roller 3 during work. Long-term slight collision will cause the needle tip of the two brush roller card clothing to wear out quickly. After wearing out, the problem of cover lap cleaning is not clean, which is to replace the elastic card clothing of the large brush roller 2 or the original high-speed cleaning roller 3 in time to ensure that the cover lap is clean. The slight collision of the two brush roller teeth will cause the original high-speed cleaning roller 3 to break after a period of operation. Most of the broken needles will enter the dust filter unit, and a small part of the broken needles will enter the inside of the high-speed working carding machine, and a part will splash out, which has a safety hazard.

[0009] 1.5 Influence the service life of the movable flat top cover card clothing. As shown in the process structure, Figure 1 The distance between the large brush roller 2 and the movable flat top cover card clothing 7 is 0.175mm~ -0.5mm. During work, in order to better clean the cover lap on the movable flat top cover card clothing, the user often adjusts the distance between the large brush roller 2 and the movable flat top cover card clothing 7 to negative distance, that is, the needle tip of the large brush roller 2 is inserted into the movable flat top cover card clothing. Long-term continuous production friction will cause the sharpness of the movable flat top cover card clothing to decrease, which affects the service life of the movable flat top cover card clothing.

[0010] 1.6 There is unreasonable design structure. The minimum distance between the original high-speed cleaning roller 3 and the outer circle of the large brush roller 2 is-1mm, and the minimum distance between the original dust removal knife 4 and the outer circle of the large brush roller is 1mm. During work, a small amount of residual cover lap on the large brush roller 2 cleaned by the original high-speed cleaning roller 3 is difficult to be removed by the original dust removal knife 4 with larger distance. SUMMARY

[0028] Figure 2 It is a sectional view of the novel movable flat cover brush roller device provided by one specific embodiment of the utility model.

[0029] Figure 3The utility model discloses a novel movable cover plate brush roller device provided in a specific embodiment of the utility model.

[0030] The signs in the drawings are as follows:

[0031] 1, big brush main transmission wheel;2, big brush roller;3, original high speed cleaning roller;4, original dust removal sword;5, high speed cleaning roller main transmission wheel;6, original air suction passage;7, movable cover plate;8, air suction cover;9, high speed cleaning roller;10, dust removal sword;11, cleaning roller frequency conversion motor;12, air suction passage. Specific embodiments

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] Please refer to Figures 2 to 3 , Figure 2 The utility model discloses a movable cover plate brush roller device's cross section schematic view provided in a specific embodiment of the utility model; Figure 3 The utility model discloses a movable cover plate brush roller device's three-dimensional schematic view (not show movable cover plate) provided in a specific embodiment of the utility model.

[0034] The utility model discloses a movable cover plate 7 brush roller device, including setting in movable cover plate 7 outside high speed cleaning roller 9 and setting in high speed cleaning roller 9 descending side (right side) dust removal sword 10. Among them, the linear speed of high speed cleaning roller 9 is far greater than the linear speed of movable cover plate 7, and the rotating speed of high speed cleaning roller 9 exceeds 1000r / min, preferably 1800~2500r / min. The outer part of high speed cleaning roller 9 is provided with a non-metallic brush, and a positive separation distance a is provided between the outer circle of the non-metallic brush of high speed cleaning roller 9 and the needle tip of movable cover plate 7, that is, the non-metallic brush of high speed cleaning roller 9 does not contact the needle tip of movable cover plate 7. A positive separation distance b is provided between the outer circle of the non-metallic brush of high speed cleaning roller 9 and the dust removal sword 10, that is, the non-metallic brush of high speed cleaning roller 9 does not contact the dust removal sword 10. Because the rotating speed of high speed cleaning roller 9 is very high, metal needle cloth cannot be used to avoid the collision of the needle tip of high speed cleaning roller 9 with the needle tip of movable cover plate 7 to generate sparks during installation and debugging, or the damage of movable cover plate 7 needle cloth after the external unexpected winding of high speed cleaning roller 9, or the safety hazard after the accidental breakage of high speed cleaning roller 9, therefore, the non-metallic brush with good toughness, good elasticity and no hair is needed to be arranged on the outer part of high speed cleaning roller 9.

[0035] The upper part of the high-speed cleaning roller 9 is provided with a suction hood 8. The area formed by the suction hood 8, the high-speed cleaning roller 9 and the dust removal knife 10 is connected to the suction channel 12. The cover plate that is peeled off by the high-speed cleaning roller 9 enters the dust filtration system along the channel.

[0036] like Figure 2 As shown, during operation, the movable cover plate 7 moves slowly in a straight line from the lower right to the upper left (moving speed 100-300 mm / min), while the high-speed cleaning roller 9 rotates rapidly clockwise (speed 1800-2500 r / min). The rotation direction of the high-speed cleaning roller 9 is along the bending angle of the needle cloth on the movable cover plate 7 to grab the cover plate flowers on the needle tip of the movable cover plate 7. The grabbed cover plate flowers rotate at high speed with the high-speed cleaning roller 9. Under the action of centrifugal force, high-speed airflow and dust removal knife 10, the cover plate flowers on the outside of the high-speed cleaning roller 9 detach from the surface of the high-speed cleaning roller 9 and enter the suction channel 12, where they are sucked away by the negative pressure suction of the dust filtration system.

[0037] The movable cover plate 7 is a crucial carding element of the carding machine, and the cleanliness of the cover plate blem on its surface significantly affects the quality indicators of the carding machine sliver. Compared to existing movable cover plate 7 cleaning devices, the novel movable cover plate 7 brush roller device provided in this application embodiment offers advantages such as better cover plate blem cleaning effect, higher operational safety, and a longer service life of the high-speed cleaning roller 9. Details are as follows:

[0038] ① The surface of the movable cover plate 7 is cleaned more thoroughly. On the one hand, the high-speed cleaning roller 9 of this application adopts a densely planted nylon structure, and its working speed is 100 to 130 times that of the large brush roller in the original related technology. This means that in the same amount of time, the brushing frequency acting on the unit area of ​​the movable cover plate 7 is increased by 100 to 130 times compared with the traditional technology, and the multiple brushings are cleaner. On the other hand, the high-speed cleaning roller 9 of this application has a very high working speed, for example, 1800 to 2500 r / min. The boundary layer airflow driven by the high-speed rotation helps to remove the cover plate blemishes on the surface of the pin teeth of the movable cover plate 7.

[0039] ② This invention solves the problem of smudge entanglement on the brush roller in the original technology. In this application, the high-speed cleaning roller 9 operates at a very high speed, and the smudges adhering to the surface of the high-speed cleaning roller 9 are easily detached from the high-speed cleaning roller 9 under the action of centrifugal force. On the other hand, the dust removal knife 10 is positioned more reasonably in this application, that is, there is no other structure for cleaning the smudges on the surface of the high-speed cleaning roller 9 in front of the dust removal knife 10, so that the dust removal knife 10 can remove the smudges on the surface of the high-speed cleaning roller 9 by effectively cutting the boundary layer airflow.

[0040] ③Safety is improved. The high-speed cleaning roller 9 of the application is of a non-metal brush structure, and the high-speed cleaning roller 9 is in contact with neither the needle tip of the movable cover plate 7 nor any other part during operation, thus avoiding the problem of needle falling in the prior art, and the application is safer to use.

[0041] ④The high-speed cleaning roller 9 has a longer service life, is more convenient to maintain, and has a lower failure rate. The high-speed cleaning roller 9 of the application has a high operating speed, and is less likely to cause the problem of cover plate hair winding around the roller compared to the prior art. In addition, compared to the prior art, the application reduces a brush roller and basically does not cause the problem of winding around the roller during production. In the case of a significant reduction in workload in terms of bearing regular oiling, high-speed cleaning roller 9 winding, and the like, the workload of cleaning and maintenance is reduced, and the probability of failure is lower.

[0042] In some embodiments, preferably, the non-metal brush of the high-speed cleaning roller 9 is a nylon brush. The nylon brush has the advantages of good toughness, good elasticity, and no fluffing, which can further ensure a longer service life of the high-speed cleaning roller 9.

[0043] In some embodiments, the movable cover plate 7 adjacent to the high-speed cleaning roller 9 moves obliquely upward, that is, the movement mode of the section of the movable cover plate 7 closest to the high-speed cleaning roller 9 is obliquely upward. This arrangement can facilitate the removal of the cover plate hair on the movable cover plate 7 by the high-speed rotating high-speed cleaning roller 9, because it is easier to remove the originally obliquely upward moving cover plate hair to the upward moving high-speed cleaning roller 9 than to remove the originally planar moving cover plate hair to the upward moving high-speed cleaning roller 9, and the cover plate hair changes the crossing angle of the movement direction by a smaller angle.

[0044] In some embodiments, the tip of the dust removal knife 10 is located in the middle upper part of the descending side (right side) of the high-speed cleaning roller 9, and the body of the dust removal knife 10 is arranged obliquely downward in the tangential direction of the high-speed cleaning roller 9. After the cover plate hair moves to the upper end of the high-speed cleaning roller 9, the outer layer of the cover plate hair is separated from the high-speed cleaning roller 9 due to the centrifugal force, and the inner layer of the cover plate hair can be cut by the dust removal knife 10 after passing through the upper end of the high-speed cleaning roller 9 to remove the cover plate hair on the surface of the high-speed cleaning roller 9, so that the tip of the dust removal knife 10 is located in the middle upper part of the descending side (right side) of the high-speed cleaning roller 9. Under the condition that the position of the suction channel 12 is certain, the body of the dust removal knife 10 can be inclined downward by a larger angle, which is more conducive to the removal of impurities.

[0045] In some embodiments, preferably, the range of the distance a is 0.1mm-0.2mm, and the range of the distance b is 0.5mm-1.5mm. The application has been applied to a carding machine, and the use effect of the aforementioned distance a and distance b is good, that is, obvious effects have been achieved compared to the prior art during production.

[0046] On the basis of the above-mentioned embodiments, more preferably, the pitch a is greater than or equal to 0.125 mm, and the pitch b is greater than or equal to 1 mm, i.e., the more optimal range of the pitch a is 0.125 mm-0.2 mm, and the more optimal range of the pitch b is 1 mm-1.5 mm.

[0047] In some embodiments, the high-speed cleaning roller is in transmission connection with the cleaning roller variable frequency motor 11. That is, the working speed of the high-speed cleaning roller can be adjusted by the variable frequency motor, and the working speed of the high-speed cleaning roller 9 in the application can be adjusted online, and the user can adjust it according to the actual working condition. Compared with the working speed of the two brush rollers in the original related art (structure) which cannot be adjusted, the application is more convenient in adjustment, use, etc.

[0048] The embodiment of the application also provides a carding machine comprising the new movable flat 7 brush roller device described above.

[0049] The carding machine provided by the embodiment of the application has the advantages of the new movable flat 7 brush roller device, and details are not repeated here.

[0050] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0051] The automatic rolling lever mechanism for the throwing tool is described in detail above. The principle and implementation mode of the application are described by applying specific examples in this paper, and the description of the above embodiments is only used to help understand the method and core idea of the application. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principle of the application, the application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the application. Therefore, the application will not be limited to the embodiments shown in this paper, but will meet the widest range consistent with the principle and novel features disclosed in this paper.
