Description

Technical Field

[0001] The utility model relates to a lint cleaning machine. Background Art

[0002] The sawtooth lint cleaning machine is a lint cleaning machine that is currently widely used, but its overall structure is generally complex. The main reason for the complex structure is that there are many movable parts, and the transportation of lint between different process components often requires the adaptation of relatively more parts. The lint is then sucked away by the dust collector, and the dust is then sucked away from the dust collector, and the dust is then sucked away from the dust collector, and the dust is then sucked away from the dust collector, and the dust is then sucked away from the dust collector. The fibers pulled by the licker-in hook are sent into the main collecting dust cage under the action of air flow.

[0003] The sawtooth lint cleaner with a gripping mechanism requires a rotating dust cage, a stripping assembly (two stripping rollers) located below the cage, a gripping and pulling section (a smooth roller and a roller) located below the stripping assembly, and a feeding section located below the gripping and pulling section. The overall height dimension is relatively large. As is easy to understand, the numerous links involved in lint handling require assurance at every stage, making design, manufacturing, and control of operating conditions relatively complex.

[0004] Another common lint cleaning machine is a pair of rollers with sawtooth lint cleaning mechanisms. Its basic operating principle is that lint, driven by air from the cotton gin or brush bag and drawn by the lint cleaning machine's fan, is transported through a pipe to a dust basket. There, the lint is adsorbed by the basket's surface. The dust-laden air flows through the basket's mesh and enters the basket, where it is discharged into the dust chamber through ducts on its left and right sides. As the basket rotates clockwise, the lint clings to the mesh until it reaches a predetermined position, where it is removed by stripping rollers positioned there, forming a uniform, continuous mat. This mat is then evenly combed by licker-in rollers. The fibers pulled by the wicks follow the licker-in rollers in a high-speed circular motion. Due to the high weight of infertile seeds, natural impurities, and large particles, they are removed by centrifugal force and blocked by seven debris removal blades. They are then collected and cleaned through a dust collection duct. When the fibers encounter a brush, they are brushed into the lint duct and sent to the collection basket for packaging.

[0005] The sawtooth lint cleaning machine with a pair of rollers is much simpler than the previous sawtooth lint cleaning machine, but its cleaning capacity is relatively weaker. At the same time, since there is still a part between the dust cage and the licker-in for lint to be received, the overall structure is still complicated. Utility Model Content

[0006] The purpose of the utility model is to provide a lint cleaning machine which has a relatively compact structure and maintains a relatively good cleaning effect and feeds cotton through a brush.

[0008] The machine body is provided with a cotton collecting chamber and a cleaning chamber adjacent to each other, wherein the machine body is provided with a cotton inlet channel and an air inlet channel corresponding to the cotton collecting chamber, and is provided with a dust grid and a cotton outlet channel corresponding to the cleaning chamber;

[0009] The fixed dust cage net is an arc-shaped dust cage net fixed in the machine body, the fixed dust cage net leaves the cotton inlet channel out of the way, shields the air inlet channel, and is located on the side of the cotton collecting chamber away from the cleaning chamber;

[0010] A brush roller is installed in the cotton collecting chamber, the axis of the brush roller is collinear with the axis of the fixed dust cage net, and is used to brush off the lint absorbed on the inner surface of the fixed dust cage net;

[0011] A licker-in roller is installed in the cleaning chamber and is located below the brush roller. The distance between the licker-in roller and the top circle of the brush roller is 5 mm to -10 mm, where "-" indicates that the licker-in roller is partially inserted between the bristles of the brush roller.

[0012] The debris removal knife is distributed on the dust grid side of the licker-in roller.

[0013] Optionally, the central angle of the fixed dust cage net is 120°~210°.

[0014] Optionally, the part of the air guiding channel located in the cotton collecting cavity has a funnel-shaped air intake opening.

[0016] When the air guiding channel is offset to the rear side of the brush roller, the offset amount is 30% - 37.5% of the diameter of the brush roller;

[0017] The offset amount refers to the offset relative to the state of being directly opposite when located directly above the brush roller.

[0018] Optionally, the cotton feeding channel is located on one side of the air guiding channel, and one side of the cotton feeding channel cooperates with the brush roller;

[0019] The central angle of the part where the brush roller cooperates with the cotton feeding channel is 55° - 75°.

[0020] Optionally, a cotton pressing plate is provided on the lower side of the cotton feeding channel, and the cotton pressing plate is used to obliquely guide the cotton downwards to the brush roller on the lower side of the cotton feeding channel; and

[0025] Optionally, the machine body is provided with air supplement holes on the wall plate at the cooperation position of the brush and the saw roller.

[0026] In the embodiment of the present utility model, the main concept is to simplify the overall structure. Furthermore, in the embodiment of the utility model, two rotating functional components are mainly used inside the machine, namely the brush roller and the sawtooth roller, while the doffer roller etc. are omitted, and the driving technical conditions require relatively less. From the implementation perspective, the raw cotton enters from the feeding channel and is partially adsorbed on the fixed dust cage net under the influence of the air drawn by the air guiding channel, and partially directly hangs on the brush roller. During this process, the raw cotton will be combed by the brush roller. At the same time, the raw cotton adsorbed on the fixed dust cage net is brushed off by the brush of the brush roller and follows the brush roller to run to the position where it cooperates with the sawtooth roller. The sawteeth on the sawtooth roller hook and comb the raw cotton on the brush roller, and transfer the raw cotton on the brush roller to the sawtooth roller at this place. The sawtooth roller carries the raw cotton to rotate. Since impurities such as immature seeds have a relatively large specific gravity, they move to the centrifugal side of the raw cotton tire on the sawtooth roller under the action of centrifugal force, suspend in the outer layer of the air flow circle of the sawtooth roller, and are impacted by the waste discharge knife and discharged. The raw cotton carried by the sawtooth roller then falls off at the outlet channel under the action of the air flow of the cotton collecting dust cage of the next process equipment, for example, and is discharged from the outlet channel. Thus, it can be seen that under the condition of simplified structure, the raw cotton can still be relatively well cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In the embodiment of the present utility model, the main idea is to simplify the structure of the lint cleaning machine. On the one hand, its intention is to save energy and reduce consumption, on the other hand, to reduce the investment in some rotating parts, reduce the links for ensuring, and make it easier to ensure the quality of lint cleaning. On the other hand, through a new lint cleaning method, it can be guaranteed that the cleaning effect is still relatively good.

[0037] Conventional lint cleaning machines, such as sawtooth lint cleaning machines, generally use a rotating dust cage to collect the lint introduced into the cotton inlet channel 12. Specifically, loose lint is introduced from the lint channel 12 through the cotton-brushing airflow. Since the cotton-brushing airflow draws air from the dust cage, the loose lint is adsorbed on the outer surface of the dust cage as the dust cage rotates. A cotton stripping roller is then provided on the lower side of the dust cage to peel off the lint adsorbed on the mesh surface of the dust cage. In this process, the dust cage rotates and needs to be equipped with a rotary seal for connection with the air-inducing device. At least a cotton stripping roller is required to peel off the lint adsorbed on the mesh surface of the dust cage. As far as the cotton collecting part is concerned, the structure is relatively complex.

[0038] In the embodiment of the present invention, the mesh surface for collecting lint is configured in a fixed manner, and the brush roller 17 is used for peeling and transporting the lint. Therefore, in the embodiment of the present invention, the lint cleaning machine is called a brush-feed lint cleaning machine.

[0039] Accordingly, the brush-fed cotton lint cleaning machine according to the present invention comprises a slightly different machine body than conventional lint cleaning machines. As a standard configuration, the machine body includes left and right wall panels and front and rear sheet metal covers. It should be noted that cotton processing machinery has defined front, back, left, and right directions. The left and right directions are also referred to as width or transverse directions, while the front and back directions are also referred to as longitudinal or length directions. Once these are defined, the up and down directions are also determined.

[0040] Among them, the left and right wall panels often have a relatively large thickness compared to the front and rear sheet metal cover panels, and are generally made of steel plates to provide the main support for the equipment inside the machine body. For example, the two ends of the brush roller 17 and the two ends of the licker-in roller 6 are usually installed on the left and right wall panels using bearings.

[0041] The composition of the wall panels is common knowledge in this field. For example, each side of the wall panel has multiple pieces, and the functions of different wall panel parts are more clearly determined, such as Figure 1The dust grid wallboard 4 shown in the figure is arranged on one side of the cleaning part and is used for installing the waste removing knife 5, the waste guiding board 3, etc.

[0042] In addition, as Figure 1 In the exemplified structure, the machine body is usually supported by the feet 1 to a predetermined height, so as to facilitate the connection of components such as the waste removing channel or the waste removing auger.

[0043] Figure 1 The exemplified structure also has a bottom frame 2, which is used as the installation base of the wallboard, for example, and is the main load-bearing part and the main installation base of other parts of the lint cleaner. The bottom frame 2, the feet 1, etc. all belong to the general configuration of the lint cleaner and will not be elaborated here.

[0044] Furthermore, in the space formed by the left and right wallboards and the front and rear sheet metal cover plates of the machine body, there are an adjacent cotton collecting cavity and a cleaning cavity. In the traditional lint cleaner, an intermediate component such as the cotton stripping roller and the drafting roller assembly described above is often required between the cotton collecting cavity and the cleaning cavity, so that the traditional lint cleaner is relatively high in height. And because there are multiple rotating components and a relatively strict cooperation relationship is required between adjacent rotating components, the overall structure is complex and the reliability is relatively weak. In the embodiment of the present invention, the cotton collecting cavity and the cleaning cavity are adjacent to each other without the need to configure a transition component, reducing the overall height of the lint cleaner and having relatively good reliability due to the reduction of the cooperation relationship.

[0045] Among them, the machine body is provided with a cotton feeding channel 12 and an air guiding channel 15 corresponding to the cotton collecting cavity. Regarding the air guiding channel 15, based on the concept of the present invention, since a fixed dust cage net is adopted, such as Figure 1 the fixed dust cage net 18 shown in the figure, while a rotating dust cage is adopted in the traditional lint cleaner, the overall technical requirements are reduced.

[0046] It should be known that the dust cage in the traditional lint cleaner is a cylindrical structure, with air ducts connected to both ends, and the dust cage needs to rotate at a predetermined speed to adsorb the lint introduced through the cotton feeding channel 12 relatively evenly on the mesh surface of the dust cage. It can be seen that the traditional dust cage needs to make a rotational motion, and both ends of the dust cage need to be connected to the air ducts through a rotating seal assembly, with a complex overall structure and it is not easy to ensure the reliability.

[0047] In the embodiment of the present invention, the fixed dust cage net 18 is fixedly arranged. The fixed dust cage net 18 does not need to form a cylindrical structure, nor does it need to be connected to the air guiding channel 15 through a dynamic seal structure. Only one external pipe is required, so the structure is more concise, and the sealing reliability is easier to ensure because it is a static seal.

[0048] In the embodiment of the present utility model, the fixed dust cage net 18 does not form a cage structure. Instead, it follows the traditional dust cage concept, which is mainly for the convenience of understanding and does not mean that it forms a cage structure. In the embodiment of the present utility model, the same is true for other technical terms. These technical terms are mainly used to describe different technical features and do not constitute a limitation on its protection scope.

[0049] Furthermore, regarding the shape of the fixed dust cage net 18, it is composed of an arc-shaped net body. The fixed dust cage net 18 is mainly used to cover the inlet of the air guiding channel 15. In other words, it is equivalent to a shielding cover.

[0050] Regarding the fixed dust cage net 18, its cooperation with the brush roller 17 needs to be considered. Therefore, there are certain requirements for its stiffness. If the fixed dust cage net 18 is made of steel plate and has relatively high self-stiffness, additional supports may not be provided. If it is made of wire mesh, auxiliary supports need to be provided.

[0051] It should be noted that since the fixed dust cage net 18 is a statically determinate dust cage net and will not be affected by centrifugal force like the dust cage net surface, it is easier to ensure the self-stiffness of the fixed dust cage net 18.

[0052] Furthermore, regarding the fixation of the fixed dust cage net 18, in Figure 1 the illustrated structure, there are several connecting ribs 16. The centrifugal side of the connecting ribs 16 can be directly fixed on the machine body or can be fixed on the machine body through an intermediate member. From Figure 1 the illustrated structure, it can be seen that there is also a component with an arc-shaped structure outside the connecting ribs 16. This component with an arc-shaped structure can be an arc-shaped frame to shorten the radial length of the connecting ribs 16 and improve the overall stiffness.

[0053] For the arc-shaped fixed dust cage net 18, it can also be strengthened using a girdle beam, which is mainly arranged on the outer surface of the fixed dust cage net 18.

[0054] It should be known that regarding the inside and outside, for the arc-shaped fixed dust cage net 18, the surface on the centrifugal side is the outer surface, and the surface on the centripetal side is the inner surface.

[0055] Based on the foregoing description, the range covered by the fixed dust cage net 18 is limited to covering the inlet of the air guiding channel 15. It should be known that due to the air guiding method adopted, obviously the inlet of the air guiding channel 15 is the end of the air guiding channel 15 located inside the machine body.

[0056] Based on the shielding of the air guiding channel 15 by the fixed dust cage net 18, carried by the brushing cotton air flow, the lint will be adsorbed on the dust cage net 18, and the rotation of the brush roller 17 will enable the lint in flight to be preliminarily combed, so that the lint is brushed off and taken away by the brush roller 17 during continuous conveying.

[0057] During this process, the lint is pulled by the brush roller 17 during flight, adsorbed and brushed on the fixed dust cage net 18, and the dust and some smaller fibers in the lint are sucked away, forming a preliminary cleaning.

[0058] Obviously, as described above, the fixed dust cage net 18 only needs to cover the entrance of the air induction channel 15. This covering does not necessarily require directly fixing the fixed dust cage net 18 at the entrance of the air induction channel 15. It can also maintain a predetermined distance, but it does not affect the covering of the entrance of the air induction channel 15. In particular, when the fixed dust cage 18 is relatively far from the entrance of the air induction channel 15, its central angle can be relatively large, which is beneficial for, for example, more dust to pass through the fixed dust cage net 18 and escape.

[0059] Furthermore, obviously, under this condition, the fixed dust cage net 18 needs to give way to the cleaning chamber and the cotton feeding channel. Therefore, the fixed dust cage net 18 needs to be configured as an incomplete cylinder, that is, an arc-shaped mesh surface.

[0060] In Figure 1 In the illustrated structure, the central angle of the fixed dust cage net 18 is about 180°. The fixed dust cage net 18 can be relatively small, but it should not be less than 120°, otherwise the dust removal effect will be relatively poor. However, it should not be too large either, otherwise it will occupy the part where the cotton feeding channel 12 intervenes and the matching part between the saw roller 6 and the brush roller 17. Therefore, the central angle of the fixed dust cage net 18 should not be greater than 210° either.

[0061] Matching the shape of the dust cage net 18, the part of the air induction channel 15 located in the cotton collecting chamber has a funnel-shaped air intake, that is, the inlet of the air induction channel 15 can be understood as a conical opening, and this conical opening gradually narrows from the inner end to the outer end to facilitate the adaptive covering of the fixed dust cage net 18.

[0062] Viewed from the positional relationship, the fixed dust cage net 18 is on the side away from the cleaning chamber in the cotton collecting chamber, and the brush roller 17 is exposed on the side close to the cleaning chamber. Both ends of the brush roller 17 are installed on the left and right wallboards through bearings. Under ideal conditions, the axis of the brush roller 17 is collinear with the axis of the fixed dust cage net 18.

[0063] Based on the surrounding relationship, the brush roller 17 is located inside the fixed dust cage net 18. Although it is semi-surrounding, it is still a clear expression in the mechanical field.

[0064] Regarding the brush roller 17, it is also a commonly used component in cotton processing machinery. However, in the embodiment of the present invention, the usage mode of the brush roller 17 is different from the conventional usage mode of the brush roller 17 used in cotton processing machinery. In the embodiment of the present invention, the brush roller 17 brushes off and carries the lint to rotate from the inside of the fixed dust cage net 18. During this process, the brush roller 17 also has the function of combing the lint when the lint enters the cotton collecting chamber.

[0065] See Figures 3 to 5 , in the illustrated brush roller 17, the brush roller shaft 174 and the wrapper plate assembly 171 fixed on the brush roller shaft 174 through the spoke plates 175 are shown. The wrapper plate assembly 171 has a cylindrical structure. Ideally, the axis of the wrapper plate assembly 171 is collinear with the brush roller shaft 174.

[0066] In Figure 3 the illustrated structure, the brush roller shaft 174 includes two "half shaft bodies". In some embodiments, the brush roller shaft 174 can also adopt a through shaft. When adopting a through shaft, a tube shaft can be used to reduce the overall weight.

[0067] When adopting the half shaft bodies as shown in Figure 3 , two spoke plates 175 are provided on each half shaft body to improve the overall support stiffness for the wrapper plate assembly 171.

[0068] Fixing holes are formed on the wrapper plate assembly 171. As shown in Figure 5 , the brush 172 can be fixed on the tile-shaped mounting plate १७६. With the help of the mounting plate 176, the brush 172 can be fixed on the wrapper plate assembly 171 through the second screw 173 as shown in the figure. In this way, the replacement of the brush 172 can be facilitated.

[0069] In some embodiments, the second screw 173 can be replaced with a rivet to improve the fixing reliability.

[0070] From Figure 4 it can be seen that whether it is the brush roller 17 used in the embodiments of the present invention or the brush roller 17 used in the traditional cotton processing machinery, the distribution of the brushes 172 in the circumferential direction of the brush roller has a certain density. As shown in Figure 4 , twenty-four brushes 172 are distributed in the circumferential direction of the brush roller 17. There are brush gaps between the brushes 172. In addition to the lint directly adhered by the brushes, part of the lint entering the lint collecting chamber at a certain speed will also get into the brush gaps and then contact the fixed dust cage net 18 due to the centrifugal force generated during the rotation of the brush roller 17. Instead of being adsorbed, it is then brushed off, and a cotton tire with a certain thickness is formed at the top circle of the brush roller 17. During the rotation of the brush roller 17, the cotton tire rubs against the inner surface of the fixed dust cage net 18, which is beneficial to the removal of dust.

[0071] In addition, in Figure 3 the illustrated structure, fins or sealing sheets can also be provided on the outer surface of the outermost spoke plate 175 to achieve relatively good sealing in cooperation with the wall panels at both ends.

[0072] Adapted to the brush roller 17, a licker - in roller 6 is provided on its lower side. The licker - in roller 6 is used for cleaning the lint cotton. Therefore, the part of the machine body at the lower part that accommodates the licker - in roller 6 is defined as the cleaning chamber.

[0073] The cleaning chamber is divided into two parts, front and rear. The part at the front (the left side in the figure is the front) is the dust grid, and the part at the rear is the cotton outlet passage 20.

[0074] In the embodiment of the present utility model, the brush roller 17 also serves as a component for conveying the lint cotton. Furthermore, the brush roller 17 directly cooperates with the licker - in roller 6 without the need to set components such as a doffer roller.

[0075] In a preferred embodiment, the top circle of the licker - in roller 6 is exactly tangent to the top circle of the brush roller 17. Since the lint cotton is under the action of centrifugal force on the brush roller 17 and is roughly located at the top circle of the brush roller 17 and slightly outward, the licker - in roller 6 has a stronger affinity for the lint cotton relative to the brush roller 17 and hooks and pulls the lint cotton off the brush roller 17 by means of hooking.

[0076] From the perspective of the rotation relationship, in Figure 1 the state shown, the brush roller 17 rotates clockwise, while the licker - in roller 6 rotates counterclockwise. There is a rotational speed difference (linear speed) between the two. The rotational speed of the licker - in roller � is greater than that of the brush roller 17, and the lint cotton is hooked and pulled off the brush roller 17.

[0077] In some options, a small distance can be left between the licker - in roller 6 and the brush roller 17. This small distance should not be greater than 5 mm, otherwise it is not conducive to the transfer of lint cotton from the brush roller 17 to the licker - in roller 6. At the same time, in some options, the licker - in bars of the licker - in roller 6 can partially penetrate between the bristles 172 of the brush roller 17. In this case, the lint cotton can be more effectively transferred from the brush roller 17 to the licker - in roller 6, but it is easy to damage the bristles 172, and the service life of the licker - in bars on the licker - in roller 6 will also be shortened. Therefore, the penetration amount of the licker - in bars into the bristles 172 should not exceed 10 mm. Therefore, in a preferred embodiment, the top circle of the licker - in roller 6 is exactly tangent to the top circle of the brush roller 17.

[0078] Regarding the cooperation relationship between the licker - in roller 6 and the waste - removing knife 5 for lint cotton cleaning belongs to the general knowledge in the field, and only a brief description is given below. In Figure 1 the illustrated structure, there are a total of five waste - removing knives 5, generally five to nine are selected. They are distributed in an arc - shaped manner on the outer side of the licker - in roller 6 at the arc section corresponding to the dust grid of the licker - in roller 6, and the distance from the licker - in roller 6 is generally less than or equal to 50 mm, but generally greater than 20 mm.

[0079] Affected by the centrifugal force, impurities with a relatively large specific gravity are pulled by the cotton fibers and rotate along with the cotton lap, presenting a state where impurities with a relatively large specific gravity are located in the outer layer of the air flow circle of the saw roller 6. The waste discharge knife 5 is located on the rotation path of the cotton fibers that pull the impurities, causing the cotton fibers to hit the blade of the waste discharge knife 5, putting the impurities in a state of emergency braking, so that the impurities are separated and discharged.

[0080] The dust grid is isolated from the cotton outlet channel 20 at least on the lower side of the array of the waste discharge knives 5. Figure 1 The impurity guiding plate 3 shown in the figure is both a guiding plate for guiding impurities downward and an isolating plate for isolating the front and back of the cleaning cavity.

[0081] In view of the fact that the cotton fibers are roughly attached to the saw roller 6 in a hooking manner, in some embodiments, a reverse hooking wind force can be applied to separate the lint from the saw roller 6.

[0082] As Figure 1 shown, the saw roller 6 rotating counterclockwise transfers the lint to the saw roller 6 at the junction with the brush roller 17, then rotates counterclockwise to the arrangement area of the waste discharge knives 5 and is cleaned. When it further runs to the lint channel 20, the lint channel 20 also creates a negative pressure in the area where the lint channel 20 cooperates with the saw roller 6 by means of air induction to suck away the lint.

[0083] In addition, in Figure 1 the illustrated structure, it is determined that there is a gap between the lower component 22 of the cotton outlet of the lint channel 20 and the saw roller 6, and this gap communicates with the outside for air replenishment, that is, the air replenishment port 21 shown in the figure is formed to facilitate the generation of air flow to convey the lint to the cotton outlet channel 20.

[0084] In addition, the waste discharge knives are distributed on the side where the dust grid of the saw roller is located.

[0085] As mentioned above, in the known lint cleaners, the channels for dust cage air induction need to be configured at both ends of the dust cage. Therefore, the position setting of the known air induction channel 15 is restricted relatively more. In the embodiments of the present invention, the setting position of the air induction channel 15 is relatively more flexible. In Figure 1 the illustrated structure, the air induction channel 15 is vertically arranged, and it can also be arranged on the side according to the piping of the air induction system.

[0086] Setting the air induction channel 15 on the upper side of the machine body can reduce the interference with the position setting of the power part. As Figure 1The first motor 11 shown in the figure is used to drive the brush roller 17 through, for example, a first chain drive mechanism, while the second motor 23 located on the lower side drives the thorn roller 6 through, for example, a second chain drive mechanism. The two chain drive mechanisms are necessarily arranged on the left side of the left wall panel or the right side of the right wall panel, which will occupy a certain space. Although in the embodiments of the present invention, the usage amount of, for example, the drive chain is reduced due to the reduction of the components to be driven, the inventor believes that setting the air induction channel 15 on the upper side of the machine body can allocate the space more effectively.

[0087] In some embodiments, the air induction channel 15 can be arranged directly above the brush roller 17, and in a more preferred embodiment, the air induction channel 15 can be offset to the rear side of the brush roller 17. When the air induction channel 15 is offset to the rear side of the brush roller 17, the offset amount is 30% - 37.5% of the diameter of the brush roller 17, so as to facilitate the construction of a Figure 1 fixed dust cage net 18 with a larger area as shown in the figure.

[0088] Obviously, based on the above description, it can be known that the offset amount refers to the offset amount relative to the state of being directly opposite when located directly above the brush roller 17.

[0089] In Figure 1 the illustrated structure, the cotton feeding channel 12 is located on one side of the air induction channel 15, and they are arranged in parallel at the upper part of the machine body. Figure 1 In the figure, the lower rear side of the cotton feeding channel 12 cooperates with the brush roller 17; correspondingly, the side of the cotton feeding channel 12 that cooperates with the brush roller 17 is the open side. After the lint is introduced from the cotton feeding channel 12, it is exported from the open side that cooperates with the brush roller 17 and is pulled by the brush roller 17 to rotate onto the fixed dust cage net 18, and then, based on the previous description, the preliminary cleaning (dust removal and relatively fine impurities) of the lint is completed.

[0090] From Figure 1 the figure, it can be seen that the central angle of the part of the brush roller 17 that cooperates with the cotton feeding channel 12 is 59°, which is beneficial to the distribution of the lint on the brush roller 17. This cooperating part should not be too large, otherwise it is easy to cause the lint to accumulate at the bottom of the cotton feeding channel 12 and cause congestion, nor should it be too small, otherwise it is easy to cause the lint to not be effectively combed and transported by the brush roller 17. Calculated by the central angle of the brush roller 17, the central angle of the brush roller 17 corresponding to this cooperating part is 55° - 75°.

[0091] Different from the traditional coordination relationship between the debris removal knife 5 and the licker-in roller 6, as well as the distribution form of the debris removal knife 5, in the embodiment of the present utility model, a specially configured debris removal knife 5 is provided on the rear side of the first debris removal knife 7 (based on the rotation direction of the licker-in roller 6, the rotation direction is forward, and vice versa is backward), which is shown in the figure as a cotton pressing debris removal knife 803, and its first function is to press the cotton. First, the lint cotton transferred from the brush roller 17 by the licker-in roller 6 is in a relatively loose state due to the centrifugal force. The above-mentioned debris removal knife 5 is set on the lower side of the cotton feeding channel, and its rear blade surface (the front and rear blade surfaces have a definite reference in the field of tool technology, which will not be repeated here) plays the role of a cotton pressing plate, and presses the loose lint cotton into a cotton batt with a relatively uniform thickness, thereby providing a cotton batt with a relatively uniform thickness for the next debris removal knife, which is beneficial to the formation of the suspended airflow circle as mentioned above, thereby improving the cleaning effect.

[0092] Correspondingly, the lower side of the cotton pressing and debris removing knife 803 cooperates with the licker-in roller 6 to form a cotton pressing gap, so as to press the lint cotton transferred to the licker-in roller 6 into a cotton batting.

[0093] At the same time, the front blade of the cotton pressing and debris removal knife 803 is as follows Figure 2 As shown, it has a relatively obvious inclined surface, and constructs the guiding part at the lower part of the cotton feeding channel 12, that is, the front blade surface of the cotton pressing and debris removing knife 803 constitutes the guiding surface, and guides the lint cotton falling to the bottom toward the brush roller 17.

[0094] In some embodiments, the cotton pressing and debris removal knife 803 may only have the cotton pressing function and be transformed into a simple cotton pressing plate. In a more preferred embodiment, it is configured into the shape of a debris removal knife, the front blade surface of which has the function of guiding the lint cotton, and the blade has the function of removing debris.

[0095] Furthermore, the minimum gap between the cotton pressing plate and the licker-in roller 6 is 1-3 mm.

[0096] Also in Figure 2 In the illustrated structure, the cotton pressing and debris removal knife 803 serving as the cotton pressing plate is installed in the machine body through a support assembly 9, and the cotton pressing plate is installed on the support assembly 9 through an adjustable structure to adjust the minimum gap between the cotton pressing plate and the licker-in roller 6, thereby adjusting the minimum gap according to the quality of the incoming lint to obtain a corresponding cleaning effect.

[0097] Figure 2 In the embodiment, the adjustment structure is configured as follows: the cotton pressing and debris removing knife 803 is connected to a seat via a connecting plate 901, as shown in FIG. Figure 2 The seat is fixed by the crossbeam 905. A pair of elongated holes 902 are opened on the connecting plate 901, and the connecting plate 901 is mounted on the seat through a pair of quick-connect pins 903. By adjusting the position of the two quick-connect pins 903 in the length direction of the two elongated holes 902, the minimum gap can be adjusted.

[0098] The quick-connect pin 903 can be replaced with, for example, a tuning bolt or the like.

[0099] In addition, since the position of the cotton pressing and impurity removing knife 803 is adjustable and there is a mating relationship between its front knife face and the Figure 2 front cotton guiding plate 103 shown in Figure 2 in order to avoid problems such as spraying, a rubber plate 101 is provided between the two to achieve sealing.

[0100] In addition, in order to avoid spraying, air supplement holes are opened on the wallboard of the machine body at the mating position of the brush roller 17 and the saw roller 6, and this structure can also effectively reduce the probability of lint blockage.
