Abstract
Description
Technical Field
[0001] The utility model relates to a component for sealing the end of a licker-in roller in a lint cleaning machine, and also relates to a lint cleaning machine equipped with the component. Background Art
[0002] The use of licker-in rollers in cotton processing equipment is relatively wide. For example, seed cotton cleaning machines, lint cotton cleaning machines, cotton openers, and cotton carding machines are generally equipped with licker-in rollers, but there are often certain differences in the licker-in rollers and their auxiliary configurations in different applications. For example, for cotton openers, there is almost no need to consider the problem of end sealing. For other forms of cotton processing machinery, there are also differences in the sealing requirements for the ends of the licker-in rollers. For example, in a cotton carding machine, the sealing requirements for the licker-in rollers are mainly to prevent cotton fibers from entering the interior of the licker-in rollers. Therefore, in addition to the use of a wrapping plate on the cylindrical surface of the licker-in roller to form a closed cylinder wall, end covers are often installed at both ends of the licker-in roller to seal the cylinder formed by the wrapping plate at both ends. As far as the lint cotton cleaning machine is concerned, the requirements for the ends of the licker-in rollers are mainly to avoid or reduce the back-absorption of impurities caused by the total cotton collection and induced draft, as well as the resulting flying lint problem.
[0003] It should be noted that the main purpose of the closed structure of the lint cleaning machine is to create a negative pressure within the machine by configuring an induced draft device at the outlet, which forces the cotton fibers to flow in a predetermined direction after being brushed off the licker-in roller. The licker-in roller in the lint cleaning machine rotates to collect the lint. The centrifugal force generated by the rotation distributes relatively heavier impurities to the centrifugal side of the cotton layer on the licker-in roller. Trash cutters are then positioned at predetermined locations to remove impurities entangled with the cotton fibers on the centrifugal side. Impurities are intended to be discharged through the impurity channel. However, due to the airflow generated by the induced draft, especially the gap between the ends of the licker-in roller and the wallboard, the impurity channel is not effectively isolated from the cotton outlet channel. This can lead to some impurities being sucked back onto the cotton fibers, affecting lint quality. With technological advancements, the processing capacity of individual cotton processing equipment has increased, and the integrated induced draft capacity required has also increased. Impurity back-drawing has become increasingly prominent when the licker-in roller ends are not properly sealed.
[0004] In addition, the end of the licker-in roller currently used in lint cleaning machines is generally equipped with a wind wing. The main function of the wind wing is to provide a certain shielding effect to prevent the flying lint from wrapping around the shaft head of the licker-in roller. However, the wind wing will also generate wind force when rotating with the licker-in roller, which is easy to produce flying lint.
[0005] In some implementations, the roller body of the brush roller for brushing off lint on the licker-in roller is a cavity body, which is used to introduce compressed air. The surface of the roller body is distributed with air outlet holes, so that while brushing off the lint, the sucked-back impurities can be blown back. However, since the air outlet holes are evenly distributed on the roller body and the air outlet direction of the air outlet holes is radial, the blowing occurs not only on one side of the impurity discharge cavity but also in other areas. Coupled with the fact that the airflow in the lint cleaner is already very complex, the blowing itself may cause the gas in the lint cleaner to be more disordered and the impurity discharge to be more difficult to control. Summary of the Invention
[0006] In view of this, an object of the present invention is to provide an end seal assembly that helps the air induction of the lint cleaner to be relatively smooth, thereby effectively reducing fiber loss and obtaining relatively good-quality lint. The present invention also provides a lint cleaner equipped with the end seal assembly.
[0007] According to a first aspect of an embodiment of the present invention, an end seal assembly is provided for sealing the end of a licker-in roller in a lint cleaner, including:
[0008] A base plate, perpendicular to the licker-in roller shaft, and the centrifugal side plate edge of the base plate corresponding to the licker-in roller is an arc-shaped plate edge coaxial with the licker-in roller. A ring plate extends toward the licker-in roller side on the arc-shaped plate edge side. The ring plate is provided with first fixing holes, and the ring plate is correspondingly an arc-shaped plate;
[0009] A pressing plate, which is an arc-shaped plate that cooperates with the centrifugal side or the centripetal side of the ring plate, and the pressing plate is provided with second fixing holes corresponding one-to-one to the first fixing holes;
[0010] A rubber sheet, which is clamped between the pressing plate and the ring plate by fasteners passing through the first fixing holes and the second fixing holes and extends toward the licker-in roller side.
[0011] Optionally, the base plate has a bottom plate joined in the circumferential direction, and the corresponding pressing plate is an integral plate or a split plate corresponding one-to-one to the bottom plate.
[0012] Optionally, the central angle of the base plate is 225°;
[0013] The bottom plate has three large plates and one small plate, where the central angle of the small plate is 45° and the central angle of the large plates is 60°.
[0014] Optionally, the radius of the outer circle of the rubber sheet is smaller than the radius of the licker-in roller bar circle, and the radius of the inner circle of the rubber sheet is larger than the distance from the centrifugal end of the air vane to the axis of the licker-in roller.
[0015] Optionally, the difference between the diameter of the licker-in roller bar circle and the radius of the outer circle of the rubber sheet is 5 - 50 mm.
[0016] Optionally, the fixing holes for fixing the base plate on the lint cleaner on the base plate are distributed on two pitch circles;
[0017] The radius difference between the two pitch circles is one-sixth to one-fifth of the radius of the arc-shaped plate edge.
[0018] Optionally, the width of the substrate in the radial direction is five-fifteenths to eight-fifteenths of the radius of the arc-shaped plate edge.
[0019] According to the second aspect of the embodiments of the present invention, a lint cleaner is provided. At the positions where the left and right wall plates of the lint cleaner are aligned with the saw cylinder, an end sealing assembly described in the first aspect of the embodiments of the present invention is provided at each position.
[0020] Optionally, the distance between the rubber sheet and the end face of the saw cylinder is 0 to 5 mm.
[0021] Optionally, the central angle of the substrate is greater than 180° to adapt to the lint channel and the waste discharge box of the lint cleaner;
[0022] Correspondingly, the lint channel corresponds to 360° - the central angle of the substrate.
[0023] It should be known that there are definite areas for discharging lint and separating impurities at the saw cylinder. The end sealing assembly does not need to globally seal the circumference at the end of the saw cylinder, and only needs to isolate, for example, the area for discharging lint. Furthermore, according to the end sealing component of the embodiments of the present invention, it is a special sealing assembly for sealing the space between the end of the saw cylinder and the wall plate in the lint cleaner. The end sealing assembly includes a substrate, a pressing plate, and a rubber sheet clamped between the circular plate of the substrate and the pressing plate. Since the circular plate of the substrate is an arc-shaped plate, by cooperating with the arc-shaped pressing plate, the rubber sheet is shaped into an arc-shaped rubber sheet, and the arc-shaped rubber sheet extends towards the side where the saw cylinder is located, thereby forming a structure that is roughly an arc-shaped cover. With the help of this arc-shaped cover, a better isolation is generated between the lint channel and the waste discharge box, and the conveying air providing the power for lint output acts more on the lint rather than the impurities, so that the air guiding is smoother and the back suction of impurities is effectively reduced. The reduction or elimination of the back suction of impurities can effectively ensure the cleaning efficiency, thereby making the quality of the lint better. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Typical features of cotton - processing technology equipment generally include wall panels, and the corresponding wall panels are arranged in parallel. The side where the wall panels are located is usually called the left and right sides of the cotton - processing technology equipment.
[0031] The left and right sides correspond to the left - right direction, which is also habitually called the width direction or the transverse direction, and is also the direction corresponding to the machine width of the current cotton - processing technology equipment.
[0032] When the left - right direction is determined, the front - back direction is also determined. The front - back direction is also called the longitudinal direction, the head - tail direction, the length direction, etc.
[0033] The front - back, left - right directions determine a basic plane, and the direction perpendicular to the basic plane is the height direction, which is also called the vertical direction. However, it should be known that in the mechanical field, the height direction is generally described from a relative perspective, that is, relative height, rather than the measurement difference in the same vertical direction.
[0034] In Figure 1 In the illustrated structure, it is the fixed structure of the end - sealing component on the wall panel in an embodiment. In the figure, the wall panel includes the frame wall panel 8, the dust - grid wall panel 1, etc. In other words, the wall panel is not an integral plate body, but is configured as several split wall panels according to different functional parts.
[0035] It should be known that when cleaning lint, the spiked roller 17 receives the incoming material and forms a cotton layer with a predetermined thickness on the spiked roller 17. A set of at least one impurity - removing knife is often arranged on a predetermined arc section on the periphery of the spiked roller 17 for chopping off impurities, and the impurities should be discharged according to a predetermined position.
[0036] Correspondingly, when the spiked roller 17 carries the lint and runs beyond the arc section where the impurity - removing knife is set, it is necessary to use, for example, a brush roller to brush off or use other components to peel the lint from the spiked roller 17, and the peeled lint is output according to a predetermined channel. Obviously, the channel for lint output and the channel for impurity output are separated from each other, and the better the isolation effect between them, the better the quality of the lint.
[0037] Furthermore, the proportion of the circumferential part of the licker-in roller 17 for cleaning occupies a relatively large part, corresponding to the substrate, that is, its central angle is greater than 180°, while the circumferential area of the licker-in roller 17 corresponding to the lint duct is the blanking area, which is relatively small, corresponding to 360° minus the central angle of the substrate.
[0038] Accordingly, in Figure 1 the illustrated structure, the sector ring plate assembled by several bottom plates 2 is the substrate, which corresponds to the part for impurity cleaning and cleaning, while the missing part corresponds to the part for lint peeling and output. Therefore, the corresponding end sealing assembly is used for the auxiliary isolation between these two parts, specifically the end sealing.
[0039] In Figure 2 the illustrated structure, it can be seen that a set of end sealing assemblies are provided at both ends of the licker-in roller 17. From the perspective of the positional relationship, the end sealing assemblies are installed on the corresponding wallboards, such as the left wallboard 9 and the right wallboard 19 shown in the figure. The left wallboard 9 and the right wallboard 19 are multi-wallboard combinations as described above. In Figure 1 what can be seen includes the dust grid wallboard 1 and the frame wallboard 8.
[0040] Among them, the licker-in roller 17 is also called the licker-in bar roller. The two ends of its licker-in roller shaft 20 are correspondingly installed on the left wallboard 9 and the right wallboard 19 through bearing seats, and it has the freedom to rotate around its own axis.
[0041] Figure 1 The bottom plate 2 shown in the figure is a sector ring plate, and the vacant part corresponding to the ring hole avoids assembly interference and movement interference with the licker-in roller 17, the licker-in roller shaft 20 and its bearing seat.
[0042] In addition, Figure 1 in the structure, the main part of the substrate composed of multiple bottom plates 2 is a larger sector ring part with typical sector ring characteristics. It is a solid structure, and only the concept of plane geometry is used to describe it. Specifically, the main part of the substrate is a sector ring plate. The smaller the coaxiality between this sector ring plate and the licker-in roller 17, the better, but the requirement for this coaxiality is not high.
[0043] Another point needs to be explained. In Figure 3 the illustrated structure, four left air wings 13 are provided on the left end plate of the licker-in roller 17. The left air wings 13 do not extend to the radial end of the licker-in roller 17. In other words, at the radial end of the air wings such as the left air wings 13, that is, the centrifugal end, there is a certain space on the end plate of the licker-in roller 17, which is beneficial for a smaller distance between the end sealing assembly and the end plate, and a contact dynamic seal can be adopted.
[0044] Furthermore, using a substrate with multiple bottom plates 2 is beneficial to the assembly of the substrate, especially since the wallboards are also multi-piece assembled structures, such as Figure 1The wallboards with a dust grid wallboard 1 and a frame wallboard 8 as shown. In particular, as described above, the coaxiality requirement between the base plate and the carding roller 17 is not high. Using several base plates 2 assembled into the base plate is beneficial to adapt to manufacturing errors and assembly errors.
[0045] Obviously, from the perspective of the mating relationship, the base plate is perpendicular to the carding roller shaft 20. And as described above, the base plate is a sector ring plate with an inner arc-shaped plate edge and an outer arc-shaped plate edge. Obviously, the inner arc-shaped plate edge is located on the centripetal side of the sector ring plate, and the outer arc-shaped plate edge is located on the centrifugal side of the sector ring plate. And based on the aforementioned reference system, obviously, the axis of the outer arc-shaped plate edge is collinear with the axis of the carding roller 17 under ideal conditions.
[0046] What is mainly involved hereinafter is the outer arc-shaped plate edge. For the convenience of description, it is simply referred to as the arc-shaped plate edge. On the side of the arc-shaped plate edge, the base plate has a ring plate extending towards the carding roller side. Since the ring plate is used for clamping, for example, the wire clamping rubber 5 as shown in Figure 1 it can also be defined as a static clamping plate. And Figure 1 the pressing plate 4 used to press, for example, the wire clamping rubber 5 onto the ring plate in
[0047] can also be defined as a moving clamping plate.
[0048] Correspondingly, the ring plate is provided with a first fixing hole, and the ring plate is correspondingly an arc-shaped plate. Obviously, under ideal conditions, this arc-shaped plate is coaxial with the carding roller 17.
[0049] The pressing plate 4 is an arc-shaped plate that fits with the centrifugal side or centripetal side of the ring plate. The way of fitting the pressing plate 4 with the centripetal side surface of the ring plate is preferred, and one end of the pressing plate 4 can also be supported on the base plate surface.
[0050] Correspondingly, the pressing plate 4 is provided with a second fixing hole corresponding to the first fixing hole one by one.
[0051] Regarding, for example, the wire clamping rubber 5, a third fixing hole is also provided corresponding to the first fixing hole and the second fixing hole. Thus, after the wire clamping rubber 5 and the pressing plate 4 are adjusted in place, fasteners can be used to pass through, for example, the second fixing hole, the third fixing hole, and the first fixing hole in sequence and then locked. Figure 1 and Figure 4 In the exemplified structure, rivets 6 are used. The rivets 6 are riveted correspondingly. Riveting belongs to a kind of non-detachable connection, and the structural reliability is relatively good, especially when facing fatigue loads.
[0052] In some embodiments, bolt connection can also be selected. The characteristic of bolt connection is convenient disassembly and assembly, which is beneficial to the regular replacement of the rubber.
[0053] Since both the ring plate and the pressing plate 4 are arc-shaped plates, and the rubber is a flexible material, under the clamping of the ring plate and the pressing plate 4, the rubber is shaped into an arc-shaped plate.
[0054] The arc-shaped plate made of rubber extends towards the side of the carding roller 17, and can come into contact with the carding roller 17, or a relatively small gap can be left, and the gap should not be greater than 5 mm.
[0055] Regarding the extension amount of the pressure plate 4 and the ring plate relative to the inner surface of the base plate, under the condition of ensuring reliable clamping of the rubber, it should be as small as possible. The thickness of the base plate plus the extension amount of the pressure plate 4 relative to the inner surface of the base plate is generally not greater than three-quarters of the gap between the wallboard and the carding roller 17.
[0056] In Figure 4 and Figure 5 In the illustrated structure, which represents a part of the end seal assembly, an end seal assembly is composed of several parts. The parts that make up the same end seal assembly can be completely the same or different from each other, and need to be determined according to the size of the end seal assembly and the composition of the wallboard.
[0057] In Figure 1 In the illustrated structure, the base plate is assembled circumferentially by four base plates 2, including three 60° base plates 2 and one 45° base plate 2. Obviously, the base plate 2 described here uses the size of its central angle.
[0058] Regarding the inside and outside of the base plate, obviously the side facing the carding roller 17 is the inner side, and the side facing the wallboard is the outer side.
[0059] Under the condition that the base plate adopts a split structure, the pressure plate 2 can be selected as a split plate or an integral plate, each having its own advantages and disadvantages.
[0060] From Figure 2 the illustrated structure, it can be seen that the radius of the outer circle of the wire clamping rubber 5 is smaller than the top circle radius of the carding roller 17 corresponding to the top of the carding roller bar (abbreviated as the carding roller bar circle), and the inner circle radius of the wire clamping film 5 is greater than the distance from the centrifugal end of the air wing to the axis of the carding roller 17. Thus, under the condition of relatively compact structure, relatively good sealing can be achieved.
[0061] Furthermore, the difference between the diameter of the carding roller bar circle and the radius of the outer circle of the rubber is 5 - 50 mm, and the length of the bar (the dimension in the radial direction of the carding roller) is generally 5 - 6 mm. It can be seen that under the condition that the rubber does not need to be too thick, the rubber will directly align with the end plate of the carding roller 17 only in very few embodiments. But in the main embodiments, the rubber aligns with the annular array formed by the carding roller bars on the carding roller 17.
[0062] In Figure 1 and Figure 4In the illustrated structure, the fixing holes 3 on the substrate for fixing the substrate on the lint cleaning machine are distributed on two pitch circles, which can form a relatively reliable fixation. However, in some embodiments, the fixing holes 3 can still be distributed on one pitch circle. Based on the arc distribution of the pitch circle, the fixing form with the help of three or more fixing holes 3 can have a relatively reliable fixing effect.
[0063] exist Figure 4 In the illustrated structure, since the bottom plate 2 is relatively small, the number of fixing holes 3 required does not need to be too large, such as Figure 4 The three fixing holes 3 shown in the figure are not easy to form a triangular locking structure when they are distributed on one pitch circle. The three fixing holes 3 distributed on two pitch circles can form a triangular locking structure, which has better assembly reliability.
[0064] Furthermore, in order to obtain more reliable fixation, the radius difference between the two pitch circles is one-sixth to one-fifth of the radius of the arc-shaped plate edge.
[0065] As previously mentioned, the base plate is a fan-shaped ring plate, but it should not be too large, otherwise it may interfere with the position of the bearing seat of the licker-in roller 17, etc. Even if the assembly space is relatively ample, the overall structural compactness must be addressed. At the same time, the base plate should not be too small, as this will affect the reliability of the fixation. Therefore, the radial width of the base plate is 5 / 15 to 8 / 15 of the radius of the arc-shaped plate edge.
