Description

Technical Field

[0001] The present invention relates to a waste discharge knife assembly applied to a cotton cleaning machine, and also relates to a cotton cleaning machine equipped with the waste discharge knife assembly. The cotton cleaning machine includes a lint cleaning machine and a seed cotton cleaning machine. Background Art

[0002] Cotton processing enterprises have higher and higher requirements for cotton output, and the types of gin are becoming more and more large-scale. For example, traditional lint cleaning machine models need to be matched with large-scale lint cleaning machines to fully comb and remove impurities from lint fibers and improve the appearance of lint.

[0003] The waste discharge knife is one of the main waste discharge components of the lint cleaning machine. In some applications, it is arranged on the periphery of the saw cylinder, and the cutting edge faces the opposite direction of the rotation of the saw cylinder. For example, the lint attached to the saw cylinder rotates with the saw cylinder. Since the specific gravity of impurities is greater than that of cotton fibers, under the action of centrifugal force, the impurities are located outside the lint layer on the saw cylinder and are pulled by the cotton fibers. When the impurities located on the periphery and pulled by the cotton fibers move to the position of the waste discharge knife, the cotton fibers pulling the impurities are blocked by the cutting edge of the waste discharge knife. Based on inertia, the cotton fibers continue to be carried forward by the saw cylinder, while the impurities lose the pulling of the cotton fibers due to the blockage of the cutting edge and fall off, so that the impurities fall from the gap between the waste discharge knives.

[0004] As can be seen from the above description, ideally, the cutting edge of the waste discharge knife is parallel to the axis of the lint cleaning machine, and the two ends of the waste discharge knife are usually fixedly installed on the left and right frame wallboards of the lint cleaning machine by, for example, screws. As common knowledge in "Strength of Materials", the waste discharge knife conforms to the characteristics of a beam supported at both ends, and its bending deformation is mainly affected by its shear section modulus and gravity, resulting in a phenomenon of gradually sagging from the support points to the middle, that is, the flexure phenomenon described in "Strength of Materials". The occurrence of the flexure phenomenon will cause the gap between each part of the waste discharge knife and the saw cylinder to be inconsistent, and this gap is one of the main parameters for designing, for example, the lint cleaning machine, which determines the waste discharge effect and waste discharge efficiency of the lint cleaning machine.

[0005] Furthermore, as mentioned above, with the increasing trend of the large-scale of cotton processing equipment such as gin, the machine width (measurement specification in the left and right directions, specifically referring to the width) of the corresponding lint cleaning machine is also getting larger and larger. The waste discharge knife is a component supported at both ends, and the increase in the machine width means that the length of the waste discharge knife becomes longer, which will inevitably exacerbate the inconsistency of the gap between each part of the waste discharge knife and the saw cylinder, especially in the middle part of the waste discharge knife, where the gap between this part and the saw cylinder may seriously exceed the tolerance.

[0006] In addition, since the gap only involves the static stiffness problem, when the cotton gin is in the working state, for example, the waste removing knife will be impacted by cotton or impurities, and affected by the vibration of the cotton gin itself, resulting in vibration. It should be known that the amplitude of the vibration is positively correlated with the length of the waste removing knife, further making it difficult to control the gap and affecting the waste removing efficiency. And the vibration will generate very large noise, causing noise pollution. Summary of the Invention

[0007] The purpose of the present invention is to provide a split waste removing knife assembly, which improves the stiffness of the single segment by means of segmented support, so as to ensure the waste removing efficiency and reduce the vibration of the waste removing knife. The present invention also provides a cleaning machine equipped with the split waste removing knife assembly.

[0008] According to the first aspect of the embodiments of the present invention, a split waste removing knife assembly is provided, which includes:

[0009] The frame wallboards and the middle wallboard. The frame wallboards are the left and right wallboards of the cleaning machine, and there is at least one middle wallboard, which is parallel to the frame wallboards and distributed between the left and right wallboards, forming a wallboard array, and a knife arranging space is formed between the wallboards;

[0010] The waste removing knife. A row of waste removing knives has at least two segments, and the number of segments is the same as the number of knife arranging spaces; both ends of the segment have end plates, and the segment is fixedly connected to the corresponding wallboard through the end plate.

[0011] Optionally, the distance between the two frame wallboards is 1000 - 6000 mm;

[0012] The length of the segment is 500 - 2000 mm.

[0013] Optionally, the number of segments is not more than six.

[0014] Optionally, the number of waste removing knives is 7 - 11.

[0015] Optionally, the end plate is provided with assembly holes and tool adjustment process holes;

[0016] Among them, the assembly hole is a smooth hole for passing through assembly screws; the tool adjustment process hole is a threaded hole for adapting to adjustment screws;

[0017] The tool adjustment process hole is located on the periphery of the assembly hole.

[0018] Optionally, there is a pair of assembly holes, and the axes of the two assembly holes determine a reference plane;

[0019] The impurity removal knife is a single-edge double-sided knife, with the rake face and the flank face determined. The rake face at both ends of the segmented part is the surface connected to the end plate, and at least one tool setting process hole and the rake face are on both sides of the reference plane; the remaining tool setting process holes and the at least one tool setting process hole are on both sides of the reference plane.

[0020] Optionally, a cotton pressing plate for continuing the flank face is provided at the bottom of the impurity removal knife;

[0021] The included angle between the cotton pressing plate and the flank face is 124 to 150 degrees.

[0022] According to the second aspect of the embodiments of the present invention, a cleaning machine is provided, and the cleaning machine includes the split-type impurity removal knife assembly of the first aspect of the embodiments of the present invention.

[0023] Optionally, the bottom of the middle wallboard is supported on the chassis of the cleaning machine, the front end is fixedly connected to the front cover assembly of the cleaning machine, and the trailing edge forms an arc-shaped groove, and the axis of the arc-shaped groove is collinear with the axis of the saw roller equipped with the cleaning machine.

[0024] Optionally, the front cover assembly is provided with a movable mask assembly at the position where the split-type impurity removal knife assembly is arranged;

[0025] The movable mask assembly is divided into multiple or multiple groups with the wallboard as the boundary, and the number or number of groups corresponds one-to-one with the knife arrangement space;

[0026] If it is multiple groups, each group includes an upper and lower movable mask assembly.

[0027] In the embodiments of the present invention, in order to cope with the trend of the large-scale cleaning machine, the impurity removal knife is configured into multiple segments, and a middle wallboard is correspondingly introduced to provide support for one end or both ends of the segment far from the wallboard. Since the impurity removal knife makes the support span of the supported single body smaller through the segmented method, its static stiffness is easy to ensure and it is not easy to generate vibration noise. At the same time, since its static stiffness is easy to ensure, the consistency deviation of the gap between each part and the saw roller is also relatively small, so it is easy to obtain better impurity removal efficiency.

[0037] It should be known that for both the seed cotton cleaner and the lint cleaner, the machine width determines the left - right direction of the cleaner, and the left - right direction determines the width of the cleaner. Based on this, those skilled in the art should clearly understand the front - back direction and the up - down direction in the cleaner.

[0038] For example, Figure 1 the left - right direction in

[0039] Figure 1 can be understood as the front - back direction of the lint cleaner. The axial direction of the cylinder saw 5 in the figure is the machine width direction, that is, the left - right direction of the lint cleaner. Figure 3 , Figure 3The direction of the product corresponds to the left - right direction of the lint cleaner. For cleaners such as lint cleaners, they often have relatively rigid left - right frame wallboards. As shown in the figure, the left frame wallboard assembly 8 and the right frame wallboard assembly 35, which are generally made of steel plates, constitute the frame body of, for example, the lint cleaner.

[0040] The left frame wallboard assembly 8 and the right frame wallboard assembly 35 form the main body of the main frame, serving as the installation base for other components.

[0041] Meanwhile, for example, in the case of a lint cleaner, in addition to the aforementioned main frame, it can further be configured with, as Figure 1 shown in the figure, the upper left wallboard assembly 13 and the upper right wallboard assembly 14 to accommodate the installation of the upper - part components of the lint cleaner.

[0042] Furthermore, various face - cover assemblies such as Figure 8 the upper face - cover assembly 51 and the lower face - cover assembly 48 shown in the figure are mainly based on the left frame wallboard assembly 8 and the right frame wallboard assembly 35 as the installation base. Various face - cover assemblies are mainly sheet - metal parts. Based on the axial direction of the saw roller 5, both ends of the face - cover assembly have, for example, flanges for fixed connection with the corresponding - end frame wallboard assembly. This connection method is also applicable to other face - covers. Different from the frame wallboard, the face - cover bears less force and has a complex shape. Using sheet - metal parts is easy to form and meets the usability requirements.

[0043] Regarding, for example, a lint cleaner, its machine width has gradually become larger, from 1000 mm in the early stage to greater than or equal to 4000 mm at present. The inventor believes that the traditional method of adjusting the gap between the waste - removing knife 19 and the saw roller 5 is not sufficient to address the problem of inconsistent gaps at various locations caused by the excessive length of the waste - removing knife 19.

[0044] Another point to note is that the waste - removing knife 19 is most commonly used in lint cleaners, but it is also used in some seed - cotton cleaners. In the field of cotton - processing machinery, mainly these two types of cleaners use the waste - removing knife 19. However, it should be known that as an independent product, the waste - removing knife 19 may be used in other types of cleaners in the future. In other words, the cleaners in the embodiments of the present invention are not limited to lint cleaners and seed - cotton cleaners. In the following, the lint cleaner is mainly used as an example for illustration. It should be known that for, example, a seed - cotton cleaner, the application scenario of the waste - removing knife 19 is determined and clear. In the embodiments of the present invention, the key improvement is that the waste - removing knife 19 no longer uses a through - length knife body but a segmented knife body. In addition, it also involves the assembly method of the waste - removing knife 19. For other structures or configurations of existing cleaners, the waste - removing knife 19 and its assembly method in the embodiments of the present invention can be applied under the condition of not conflicting with the present invention.

[0045] In view of the fact that the segments of the debris removal knife 19 can be understood as relatively smaller length specifications of the debris removal knife 19, which cannot be distinguished, and the segments cannot directly form the debris removal knife 19 without connection, therefore, in the embodiment of the present invention, a group of debris removal knives 19 are constructed as an assembly with the help of the frame wall panels and the intermediate wall panels, which does not mean that the split debris removal knife assembly needs to be configured with independent frame wall panels and intermediate wall panels.

[0046] In the embodiment of the present invention, the split type debris removal knife assembly represents a partial structure in the cleaning machine, and the partial structure is not sold as a single commodity. It is particularly important to note that the debris removal knives 19 are usually installed one by one, so as to facilitate the adjustment of the gap between each debris removal knife 19 and the licker-in roller 5 within the designed gap range. The same is true for the segments.

[0047] In view of this, for example Figure 1 The lint cleaning machine shown in the figure is equipped with nine debris removal knives 19, but usually the nine knives are not manufactured and sold as a commodity, but are manufactured in units of pieces and sold in units of pieces or groups.

[0048] In the known cleaning machine, both ends of the debris removal knife 19 are fixed on the left frame wall panel assembly 8 and the right frame wall panel assembly 35. However, the width of the current cleaning machine can reach 4000mm or more. Even if the debris removal knife 19 has a relatively high rigidity, it is difficult to avoid the problem of excessive bending deformation in the middle of the debris removal knife 19. A single-length knife body is difficult to adapt to the current situation of the increasingly larger width of the cleaning machine.

[0049] Different from the prior art, in the embodiment of the present invention, the cleaning machine has a middle wall panel in addition to the frame wall panel. Since the frame wall panel is often not a simple plate body, it is usually represented by, for example, a left frame wall panel assembly 8. In the following, for the convenience of description, the left frame wall panel assembly 8 and the right frame wall panel assembly 35 are collectively referred to as frame wall panels, and the middle wall panel is represented by the same. Figure 3 The intermediate wall panel assembly 34 is shown in FIG. Unless otherwise specified, the rack wall panels and intermediate wall panels are collectively referred to as the description objects hereinafter.

[0050] It should be noted that there are currently some treatment methods for the deflection deformation of the debris removal knife 19, but it should be understood that the longer the debris removal knife 19 is, the more complicated the treatment methods are and the more difficult it is to adjust, especially in the working state, affected by the vibration of the cleaning machine itself and the impact of lint, etc., under the same working conditions, the debris removal knife 19 that is too long will have a larger amplitude. When the debris removal knife 19 is relatively short, the amplitude caused by the vibration is smaller.

[0051] In view of this, under the condition of equal machine width, the debris removal knife 19 is divided into sections, and each section has the feature of being supported at both ends, thereby fundamentally solving the dilemma of restricting the further increase of the machine width.

[0052] Therefore, in the embodiment of the present invention, firstly, a traditional rack wall panel should be provided, and at the same time, an intermediate wall panel should be provided, and at least one intermediate wall panel should be provided. Figure 3 A middle wall panel assembly 34 is provided. For the convenience of manufacturing and assembly, the wall panel spacing of the wall panel group consisting of the rack wall panel and the middle wall panel is equal, or in other words, in a preferred embodiment, the wall panels in the wall panel group are evenly arranged.

[0053] And it is obvious that the wall panels in the wall panel group are parallel to each other.

[0054] from Figure 3 It can be seen that, affected by the middle wall panel assembly 34, there is a gap in the debris removal knife 19, and the gap should be as small as possible or the number should be small. In view of this, the number of segments should not be too many, preferably less than or equal to seven segments.

[0055] See also Figure 6 The front blade surface of the debris removal knife 19 is fixedly connected to the end plate 31 at the end of the debris removal knife. This structure makes the combination of the debris removal knife 19 and the end plate 31 relatively reliable, but it should also be known that the intermediate wall panel is not the same as the frame wall panel. At least the intermediate wall panel has an arc-shaped notch to allow the licker-in roller 5 to be opened. The arc-shaped notch can allow the segment to have an extension section under the condition of meeting the connection with the end plate 31. The extension section can extend outward beyond the outer end surface of the end plate 31.

[0056] It should be known that it is easy to understand that the space between the two end plates 31 is inside, and the two end plates 31 are away from each other, that is, outward. In view of the fact that there is no need to consider the problem of exceeding the end plates 31 at the rack wall plate, the main consideration is the problem of the debris removal knife 19 at the middle wall plate exceeding the outer end surface of the end plate 31, which is used to reduce the measurement of the missing position, as long as there is no assembly interference between the segments.

[0057] In addition, even if a portion beyond the outer end surface of the end plate 31 is provided, the cleaned impurities still cannot be discharged because the portion defining the arc-shaped notch is still solid. In some embodiments, the fan-shaped cylindrical surface of the arc-shaped notch can be grooved to allow the impurities to flow down the groove.

[0058] Further Figure 4 As shown, the left rack wall panel assembly 8 shown in the figure is regarded as the middle wall panel assembly 34, and the groove can be a groove with a fan-shaped cross section and goes down along the inner surface of the arc-shaped opening of the middle wall panel, so the impurities cleaned out of the segmented part beyond the outer surface of the end plate 31 can go down along the groove, and Figure 4 At the lower end, the impurities lose support and fall.

[0059] It should be known that the thickness of the middle wall panel affects the amount of the aforementioned "gap", which obviously does not need to be too large. Therefore, here, the back side of the impurity removal knife 19 can be relatively small to form a material leakage space so that impurities can flow downward.

[0060] If the problem of missing debris removal knife 19 caused by the middle wall panel is solved, the number of middle wall panels can be appropriately increased, but not too many, because too many segments will greatly increase the difficulty of assembly. Therefore, even so, the number of segments should not be greater than ten.

[0061] For the convenience of description, taking the wall panel group as a reference, a knife row space is formed between adjacent wall panels, and each segmented debris removal knife 19 is sequentially installed on the two wall panels corresponding to the knife row space.

[0062] As mentioned above, the debris removal knives 19 are usually installed one by one, and the gaps between them and the licker-in rollers 5 are adjusted one by one. Therefore, the spacing between adjacent wall panels should not be too small to facilitate the assembly operation of the assembly workshop workers. In view of this, the spacing between adjacent wall panels should not be less than 500mm. At the same time, as mentioned above, when the segment is too short, it will inevitably increase the difficulty of assembly, and at the same time, it will also make the number of vacancies increase under the condition of the determined machine width, and the cleaning efficiency may be affected.

[0063] The length of the segment should not be too long, otherwise the value of using the segment will be lost. The segment should not be larger than 2000mm.

[0064] Furthermore, before the split type debris removal knife assembly was proposed, the technicians in this field had no motivation to use a segmented method to deal with the problem of inconsistent gaps between the debris removal knife 19 and the licker-in roller 5 caused by flexural deformation, and did not consider under what circumstances the split type debris removal knife assembly could be introduced. The inventor believes that although the split type debris removal knife assembly is proposed to solve the inherent defects of the debris removal knife 19 when it is long, it is still applicable to traditional cleaning machines even with relatively short machine widths, such as cleaning machines with a machine width of 2000 mm or less.

[0065] The machine width is determined by the distance between the two frame wall panels.

[0066] In addition, as to whether a cleaning machine with a smaller machine width is applicable, it has been pointed out in the previous text that the distance between adjacent wall panels should not be less than 500 mm. Therefore, for a known separable cleaning machine, its machine width should not be less than 1000 mm.

[0067] Regarding the applicability of the maximum machine width, there is no restriction in principle, but as another consideration, if the machine width is too large, the necessity of a single cleaning machine is reduced. In other words, multiple cleaning machines can be connected in parallel to obtain greater cleaning efficiency.

[0068] As can be seen from the above description, the so-called split waste removing knife assembly is relative to the full-length waste removing knife 19. In the embodiment of the present invention, it is equivalent to dividing the waste removing knife 19 into several segments, and the number of segments is the same as the number of knife arranging spaces, while the adjacent wallboards determine the knife arranging spaces, which is equivalent to the number of knife arranging spaces being the number of wallboards - 1.

[0069] The segments are the same as the known waste removing knife 19, and both ends are provided with end plates 31 for the assembly of the waste removing knife 19 on the corresponding wallboards.

[0070] And for the adaptability in terms of specifications, the lengths of the segments of the waste removing knife 19 are the same, but it is not an inevitable choice that the lengths of the segments of the waste removing knife 19 are the same, and the situation where the lengths of the segments are different can also be adopted.

[0071] Based on the foregoing description, when the distance between the two frame wallboards is 1000 - 6000 mm, the split waste removing knife assembly can be considered. The length of each segment is 500 - 2000 mm, and the number of segments should not be too many, usually not more than six.

[0072] Regarding the machine width, that is, the relationship between the distance between the two frame wallboards and the segment length, it can be adapted in a positively correlated manner. That is, when the distance between the two frame wallboards is relatively large, relatively long segments can be selected, but relatively short segments can also be selected.

[0073] After adopting the split waste removing knife assembly, since the support distance at both ends of the monomer, that is, the segment, becomes smaller, a knife body with relatively small self-rigidity can be selected, so that more waste removing knives 19 can be arranged in the same space. Generally, 2 - 3 more knives can be arranged, and the total number of waste removing knives 19 can reach up to eleven at most.

[0074] Considering the existence of the aforementioned vacancy, the number of waste removing knives 19 should not be too small, usually not less than seven. Further, it is more preferable to have not less than eight.

[0075] Further, from Figure 6 it can be seen that multiple holes are opened on the end plate 31, including three threaded holes 40 and two light holes 41. The three threaded holes 40 are arranged in a triangular layout, and the axis connection line of the two light holes falls within the corresponding triangular area.

[0076] Among them, the light holes 41 form assembly holes for the segments to be assembled on the corresponding wallboards by means of the end plate 31. The assembly is carried out by using, for example, the hexagon socket head cap screws 30 shown in Figure 3, and for example, the hexagon socket head cap screws 30 are assembly screws.

[0077] And the screw holes 40 serve as tool setting process holes, and the adapted, for example, hexagon socket set screws 29 serve as adjustment screws.

[0078] Accordingly, the tool-adjusting process holes are located around the assembly holes based on the aforementioned triangular layout or the like, and the corresponding tool-adjusting methods are as follows:

[0079] First, the assembly screws are screwed in place but not pre-tightened. At this time, there is a certain gap between the end plate 31 and the wall plate; or after the impurity-removing knife 19 is installed in place, the assembly screws are loosened first. Use a feeler gauge to measure whether the gap between the impurity-removing knife 19 and the sawtooth cylinder 5 exceeds the tolerance. If it exceeds the tolerance, then by adjusting the screws, the end plate 31 takes the assembly screws as the fulcrum and the adjusting screws as the force application points, that is, the adjusting screws press against the wall plate, and the reaction force of the wall plate causes the end plate 31 on the side where the adjusting screws are located to generate a turning moment, so that the tool body with the end plate 31 as the base plate is deformed, gradually bringing the gap within the predetermined range, and then the assembly screws are tightened. Finally, check whether the gap exceeds the tolerance again.

[0080] After the impurity-removing knife 19 adopts a split structure, further adjustment based on the light holes 41 and the threaded holes 40 of the end plate 31 can obtain better consistency of the gaps at various positions of the impurity-removing knife 19 and keep the gap within the predetermined range.

[0081] By using a pair of assembly holes, the segmented part can be reliably locked, and the axes of the two assembly holes determine the reference plane; accordingly, the impurity-removing knife 19 is a single-edge two-sided knife, and the front tool face and the rear tool face are determined. Regarding the front tool face and the rear tool face, after the usage mode of the impurity-removing knife 19 is determined, the front tool face and the rear tool face are determined, and the determination method belongs to the general knowledge of the tool, such as Figure 6 shown, in Figure 6 the tool state shown, the upper surface of the impurity-removing knife 19 is the front tool face, and the plane of the impurity-removing knife 19 in the figure that jointly determines the cutting edge with the front tool face is the rear tool face, which is the tool face corresponding to the inclined waist edge of the impurity-removing knife 19 in the shape of a right trapezoid in the cross-section in the figure.

[0082] Furthermore, the front tool face parts at both ends of the segmented part are the surfaces connected to the end plate 31, and at least one tool-adjusting process hole and the front tool face are located on both sides of the reference plane; the remaining tool-adjusting process holes and the at least one tool-adjusting process hole are located on both sides of the reference plane, so as to achieve a better tool-adjusting effect.

[0083] For example Figure 6 the three threaded holes 40 shown in the figure can perform tool adjustment at three positions, so that the adjustment of the turning moment of the end plate 31 can be realized at multiple positions.

[0084] Figure 6In it, the cross-section of the impurity removal knife 19 is generally in a right trapezoidal structure. The surface corresponding to the long bottom is the front knife surface of the impurity removal knife 19 mentioned above, and the surface corresponding to the inclined waist side is the rear knife surface. A cotton pressing plate 36 is installed on the surface corresponding to the short bottom. The gap between the end of the cotton pressing plate 36 and the licker-in 5 is for the lint to pass through, preventing the lint from further expanding radially on the licker-in 5.

[0085] In terms of structure, the cotton pressing plate 36 is continuous with the rear knife surface, but they are not coplanar. Instead, there is an included angle between them, and this included angle is 124° to 150°.

[0086] Figure 1 The structure of a lint cleaner is shown. It should be known that there are many types of lint cleaners, but the impurity removal knife 19 is commonly used in various lint cleaners. And this application does not involve the distribution form such as the position of the impurity removal knife 19 in the cleaner. Instead, it mainly uses a split impurity removal knife 19 to replace the impurity removal knife 19 that is continuous in the machine width direction. Therefore, for the lint cleaner illustrated in the figure, it is mainly for reference by those skilled in the art.

[0087] Compared with the traditional cleaner, in the embodiment of the present invention, an intermediate wallboard needs to be configured, and the intermediate wallboard needs auxiliary support to be arranged between the two frame wallboards.

[0088] Figure 1 In it, a chassis 27 is provided at the bottom of the cleaner. The chassis 27 is usually also the installation base of the left and right frame wallboards, and the intermediate wallboard can also be directly installed on the chassis 27.

[0089] As Figure 1 shown, the front cover 15 of the dust cage is an arc-shaped sheet metal part. That is, there is space above the licker-in 5 in the figure where a beam body, such as a cross beam, can be installed. And as Figure 3 shown, the upper end of the intermediate wallboard assembly 34 has a connecting plate 33, and this connecting plate 33 can be fixedly connected to the cross beam. And the two ends of the cross beam are fixedly connected to the left and right frame wallboards. This is the upper connection of the intermediate wall.

[0090] In addition, Figure 3 In it, the connecting plate 33 has an oblong hole 32, and the extending direction of the oblong hole 32 is parallel to the extending direction of the impurity removal knife 19 to accommodate manufacturing errors.

[0091] Figure 1 And Figure 2 In it, a ring beam 28 is installed on the upper side of the chassis 27. The ring beam 28 can be a square tube or can be made of a channel steel member and a plate member as shown in the figure. The channel steel member can form small segments, and the segmentation method of the small segments is the same as that of the impurity removal knife 19. The two ends of the channel steel member are welded with flat plates, and fixing holes are opened on the flat plates. The intermediate wallboard is then fixed through Figure 3 the connecting holes represented by the center line at the lower end of the intermediate wallboard assembly 34 in it, such as using bolts or screws.

[0092] In addition, Figure 1 In the [specific context], at the position corresponding to the right dust grid wall panel assembly 22, the space is relatively large, and a beam body can be set, for example, for strengthening the connection of the middle wall panel.

[0093] For convenient maintenance, as Figure 8 shown, a front cover assembly is provided at the front side of the position of the carding cylinder 5 for constructing a waste discharge chamber. Figure 8 In the [specific context], the front cover assembly is an assembly. The uppermost part is the upper cover assembly 51, which can be fixedly arranged, corresponding to the front side of the dust cage front cover 15 in the [specific context]. The lower cover assembly 48 is located at the lowermost part, while the middle face cover assembly adopts an openable face cover assembly, thus forming two sets of movable face cover assemblies. Figure 1 The number of groups of the movable face cover assemblies is the same as the number of groups of the segments and corresponds one by one to the knife arrangement space.

[0094]

[0095] Figure 7 The movement mode of the movable face cover is shown in the figure. In the figure, for example, for the upper right movable face cover assembly 24, its lower end is hinged to the left and right frame wall panels or an independently arranged door frame, and the upper end is connected to the above-mentioned dust grid wall panel assembly through a pull rod 46. There is an elongated hole 45 arranged along the pull rod 46 on the pull rod 46. One end of the pull rod 46 is hinged to the movable face cover assembly, and the hinge shaft of the dust grid wall panel assembly can move along the elongated hole 45 in the elongated hole 45, thus forming a triangular mechanism. In the figure, for example, the upper right movable face cover assembly 24 rotates counterclockwise and buckles. When it needs to be opened, push the upper right movable face cover assembly 24 inward and open it by means of the restoring force of the spring steel plate 43.

[0096] Since the movable face cover assembly is not affected by other external forces, its combination with the covered position can be a combination depending on friction. For example, the movable face cover assembly and the corresponding cover opening are joined through rubber parts, for example.​
