Description

Technical Field

[0001] The invention relates to a windproof structure used for windproofing between a licker-in roller end and a wallboard in a lint cleaning machine. The invention also relates to a lint cleaning machine equipped with the windproof structure and a windproof component used for constructing the windproof structure. Background Art

[0002] Figure 1 The figure shows a schematic diagram of the structure of a lint cleaning machine, and its working principle is that the lint adsorbed by the dust cage 7 is peeled off by the stripping roller 6 located below it, and then is clamped and fed to the licker-in roller 3 by the feeding roller 5 located below the stripping roller 6. The licker-in roller 3 usually has a high rotation speed. Based on the centrifugal effect, the debris adhered to the lint will be thrown out to the centrifugal side, and then cut off by the debris removal knife 4 arranged on the outside of the licker-in roller 3.

[0003] The lint wrapped on the licker-in roller 3 is peeled off by the cotton picking plate located on the upper left side of the cotton outlet channel 9, and the peeled lint is sucked away by wind along the cotton outlet channel 9. The equipment that provides wind power is called the total cotton collection and induction equipment in the lint processing machinery. According to the actual working conditions, the air induction capacity of the total cotton collection and induction equipment can be adjusted.

[0004] exist Figure 1 As can be seen in the figure, the licker-in roller 3 is located in the middle of the cotton box 2. Usually, Figure 1 The left side is called the front side of the lint collector. Figure 1 The right side in the figure is called the rear side of the lint cleaning machine, and the direction perpendicular to the paper surface is the left and right sides of the lint cleaning machine. In the figure, the licker-in roller 3 is between the cotton outlet channel 9 and the space inside the cotton box 2. In order to avoid movement interference, a gap needs to be left between the licker-in roller 3 with a rotating function and the left and right wall panels. The air induced by the total cotton collection and air induced device will inevitably cause the pressure in the cotton outlet channel 9 to be lower than the pressure in the cotton box 2, causing some dust to be sucked into the cotton outlet channel 9 through the gap, thereby reducing the cleaning effect of the lint cleaning machine.

[0005] Currently, there is no wind-proof measure for the licker-in roller 3 and the left and right wall panels, which makes the wind-inducing adjustment of the total cotton collecting air-inducing equipment very cautious, which not only affects the cleaning effect, but also affects the lint conveying efficiency.

[0006] also, Figure 1 The lint cleaning machine shown is an airflow brushing lint cleaning machine, which has higher requirements for the total cotton collection and ventilation equipment. The traditional brush brushing lint cleaning machine has relatively low requirements for the total cotton collection and ventilation equipment. With the development of technology, the lint cleaning machine using airflow brushing lint is more and more widely used, and the requirements for wind protection between the end of the licker-in roller 3 and the wall panel will become higher and higher.

[0007] However, it is to be understood that the embodiments of the present invention do not exclude the configuration of a windproof component in a conventional brush-brushed cotton lint cleaning machine. Summary of the invention

[0008] In an embodiment of the present invention, a windproof component is provided for windproofing between the end of the licker-in roller and the wallboard, so as to improve the windproofing ability between the impurity discharge space and the cotton outlet channel in the cotton box. The present invention also provides a windproof structure based on the windproof component, and a lint cleaning machine with the windproof structure.

[0039] Since many cotton processing machines rely on wind power for transportation, they often need to be configured with a relatively closed box in structure, such as Figure 1 The cotton box 2 shown in the figure. The board body for building the box body around is usually called wall panel.

[0040] In terms of location, based on the material flow, cotton processing machinery has a definite front and back, such as Figure 1 The left side shown in the figure is the front side of the lint cleaning machine, and the right side in the figure is the rear side of the lint cleaning machine. The left and right sides of the lint cleaning machine are perpendicular to the paper surface.

[0041] Figure 1 The lint cleaning machine structure shown is a common lint cleaning machine structure, but it is not the only lint cleaning machine structure. However, in most lint cleaning machines, the two stripping rollers 6 used to strip off the lint absorbed on the dust cage 7 and the two feeding rollers 5 used to transport the lint stripped by the two stripping rollers 6 downward are roughly in an up and down relationship in terms of orientation, but the position may deviate in the horizontal direction depending on different choices.

[0042] Figure 1 The structure shown is a lint cleaning machine structure based on airflow brushing. The windproof component and windproof structure based on the embodiment of the present invention are also applicable to lint cleaning machines based on brushing.

[0043] At the front of the cotton box 2, the impurity removal knife 4 removes some impurities wrapped around the licker-in roller 3 and guides them out of the cotton box 2 from the impurity plate located at the front and lower side of the licker-in roller 3. The space of the cotton box 2 in front of the licker-in roller 3 is the impurity removal space, and the impurities fall along the impurity plate, and the impurities are prevented from entering the space behind the licker-in roller 3, especially the cotton outlet channel 9, as much as possible.

[0044] At the front side of the waste plate, the bottom of the cotton box 2 is open, and an auger can be set at the waste discharge place to discharge the waste. The auger is not shown in the figure, but in the preferred embodiment, it is best to configure an independent auger or other types of waste discharge components to prevent the waste from being sucked into the cotton discharge channel 9.

[0045] In addition, an air supply port is left between the lower channel wall plate in the channel wall plate 8 and the licker-in roller 3, and the air supply port and the impurity discharge space need to be isolated.

[0046] The lint in the cotton outlet channel 9 is mainly transported by wind, and is generally transported by wind induced by the total cotton collecting air induced device, or in other words, the lint in the cotton outlet channel 9 is sucked away by suction.

[0047] In the embodiment of the present invention, the windproof component is essentially a component used to construct a dynamic sealing structure, and windproof does not mean that no leakage can occur.

[0048] It is easy to understand that static seals themselves have different sealing levels, not to mention dynamic seals, which have lower sealing capabilities than static seals.

[0049] See the instruction manual Figure 2 and attached Figure 3 A wind-shielding component is shown, and its main structure is shown as a fan-ring structure in the figure, but the use of a circular ring structure is not excluded.

[0050] Windshield components Figure 1 and Figure 4 As can be seen in the figure, there is one on each of the left wall panel 21 and the right wall panel 22, and the position is aligned with the end of the licker-in roller 3. In terms of assembly form, if the windproof component is a fan ring structure as a whole, its axis is coaxial with the licker-in roller 3. For the convenience of description, whether the windproof component is a fan ring structure or not, the basic reference system based on the fan ring structure is adopted.

[0051] The windproof component comprises:

[0052] Base, such as Figure 2 The assembly is mainly formed by a base plate 11 and an assembly plate 14, wherein the base plate 11 is represented as an attachment portion for attaching a sealing component, and the assembly plate 14 and other structures are collectively referred to as a seat portion for assembling a windproof component on a wall panel.

[0053] A sealing component is also provided, which is used to construct a sealing interface. In other words, under the assembly condition, the sealing component should be the part of the windproof component that cooperates with the licker-in roller 3. Therefore, the sealing component needs to be relative to the end of the licker-in roller 3, and the seal formed is a dynamic seal.

[0054] The sealing component is fixedly mounted on the attachment portion.

[0055] exist Figure 2 In the structure shown, the overall shape of the windproof component is a fan ring structure. In other words, relative to the circular end surface of the licker-in roller 3, it is an incomplete structure. Figure 1 It can be seen from the structure shown that the parts that need to be blocked are the left and right sides of the entrance of the cotton outlet channel 9. If a circular ring system is adopted, it will inevitably lead to a larger overall structure and cause waste.

[0056] In some embodiments, the attachment portion is an arc-shaped plate with a central angle of not more than 180 degrees and not less than 100 degrees, that is, Figure 2 The substrate 11 shown in the figure is an arc-shaped steel ring as a whole, and the surface is galvanized.

[0057] When in the installed state, the arc-shaped base plate 11 and the licker-in roller 3 are coaxial.

[0058] exist Figure 1In the structure shown, the lower side of the base plate 11 extends to the position of the lowest debris removal knife 4, and the upper end extends to the position of the cotton picking plate. The central angle of the base plate 11 formed thereby is about 140 degrees, and can be processed according to 140 degrees during manufacturing.

[0059] The base plate 11 can be slightly longer to extend the sealing interface to obtain a better sealing effect, or slightly shorter to reduce the retardation of the sealing interface to the licker-in roller 3.

[0060] In addition, since the angles of the licker-in roller 3 wrapped around the inlet of the cotton outlet channel 9 are different in lint cleaning machines of different manufacturers, the central angle of the base plate 11 is positively correlated with the angle of the licker-in roller 3 wrapped around the inlet of the cotton outlet channel 9 .

[0061] In most applications, the angle at which the cotton outlet channel 9 wraps around the licker-in roller 3 is similar. For this reason, based on the assembly characteristics of the aforementioned windproof component on the wall panel, that is, the lower end extends to the location of the lowest debris removal knife 4, and the upper end extends to the cotton picking board, the central angle of the adapted attachment portion is 130-145 degrees.

[0062] Generally, sealing components are made of materials with good bending properties, such as rubber used for sealing; in some applications, materials with a certain rigidity can also be selected, such as polytetrafluoroethylene plates or modified polytetrafluoroethylene plates. Regardless of the material of the sealing component, the sealing component can be directly assembled on the substrate 11 because the substrate 11 provides basic support.

[0063] For example, a polytetrafluoroethylene plate has a certain rigidity and can be directly assembled on the substrate 11 by screws, and the number of screws is preferably 4 to 8.

[0064] In some implementations, the sealing component can be fixed on the substrate 11 by bonding, and metal glue can be used for bonding, which has high bonding strength.

[0065] For some panels with a certain rigidity, they can be fixed by means of riveting, for example.

[0066] In some embodiments, the adapter is used to ensure that the sealing component, such as a rubber material, maintains a good shape. To this end, an arc-shaped pressing plate 13 is provided, which is coaxial with the attachment portion. Figure 2 As can be seen in the figure, the pressing plate 13 presses on the outer surface of the sealing plate 12, while the base plate 11 supports the inner surface of the sealing plate 12.

[0067] In other embodiments, the pressing plate 13 may be pressed on the inner surface of the sealing plate 12 , while the base plate 11 supports the outer surface of the sealing plate 12 .

[0068] Therefore, the pressure plate 13 can press the sealing component on the centrifugal side surface of the attachment portion, or on the centripetal side surface of the attachment portion. Figure 2 The structure in which the pressing plate 13 presses the sealing plate 12 onto the centrifugal side surface of the base plate 11 is relatively more convenient to assemble.

[0069] The base plate 11 and the pressing plate 13 can be made of steel, such as stainless steel, or aluminum alloy, which have high rigidity and low cost. Under this condition, when the sealing member is made of rubber, the rubber sealing plate 12 can maintain an arc structure through the clamping of the base plate 11 and the pressing plate 13.

[0070] The axial end face of the regular arc-shaped structure of the sealing plate 12 matches the end face of the licker-in roller 3, so that a good dynamic seal can be easily obtained.

[0071] Furthermore, the sealing member protrudes axially outwards from the base, avoiding a rigid base, e.g. Figure 2 There is motion interference between the substrate 11 and the licker-in roller 3 shown in FIG.

[0072] The protruding portion should not be too long, and should usually be controlled within 5 mm, and should not be longer than 10 mm. An overly long soft sealing plate 12 is prone to deformation and affects the sealing effect.

[0073] When the pressing plate 13 is provided, in some embodiments, the assembly structure of the pressing plate 13 on the attachment portion is: a screw hole is provided on the attachment portion, and a light hole is provided on the pressing plate 13 in an aligned manner, adapted for screw assembly. This structure is relatively simple, but during assembly, it is not easy for the screw to align with the screw hole because the screw hole is blocked by the sealing plate 12. However, under the condition of guaranteed manufacturing accuracy, the problem of screw hole alignment is not a big problem.

[0074] In some embodiments, studs are pre-installed on the attachment part, and light holes are opened on the pressure plate 13 and the sealing component in alignment. After the sealing component and the pressure plate are installed on the attachment part, the nut 17 is used to press the pressure plate 13.

[0075] The studs can be welded on the base plate 11, or can be fixed on the base plate 11 by using metal glue. In addition, the base plate 11 is pre-opened with threaded holes, and the studs can be pre-fixed on the base plate 11 by threaded connection.

[0076] exist Figure 2 In the structure shown, the seat is a fan ring plate, such as Figure 2 The assembly plate 14 shown in the figure has an overall shape of a fan ring structure, and the fan ring plate is connected to the end of the attachment portion opposite to the wall panel. Figure 2 In the figure, four round holes are opened on the mounting plate 14, and the four round holes are used as mounting holes, and the mounting plate 14 is mounted on the corresponding wall panel using screws.

[0077] In addition, an arc-shaped groove may be pre-opened on, for example, a wall panel, and glue may be filled into the groove to embed the assembly plate 14 into the arc-shaped groove and adhere it.

[0078] exist Figure 4 In the structure shown, the sealing component is mounted on the wall plate and is adapted to Figure 4 In the left wind shelter structure 1A and the right wind shelter structure 1B shown in the drawings, the position of the sealing plate 12 is roughly equivalent to the outer diameter of the licker-in roller 3.

[0079] Furthermore, when the attachment portion is an arc-shaped plate, the windproof component is offset to the side where the cotton outlet passage 9 is located at the position where the wall panel and the licker-in roller 3 are aligned, and the overall structure is relatively compact.

[0080] In addition, the inner diameter of the arc-shaped plate is less than or equal to the outer diameter of the licker-in roller 3 wrapping plate;

[0081] The outer diameter of the arc structure formed by the sealing component after being pressed on the arc plate is larger than the outer diameter of the licker-in roll cover plate, and the formed windproof structure 1 is relatively compact and still has a good sealing effect.

[0082] exist Figure 1 In the structure shown, the rear end of the lower channel wall panel that constructs the cotton channel 9 is fixed to the rear wall panel of the cotton box, and the front end is installed on the left and right wall panels by adjusting the structure;

[0083] An air supply port is left between the front end of the lower channel wall plate and the licker-in roller 3;

[0084] The wind-shielding structure at the lower side of the licker-in roller 3 at least extends forward beyond the air supply port.
