Background

Fig. 1 shows a schematic structural view of a lint picker, which operates on the principle that lint picked up by a dust cage 7 is stripped by a stripping roller 6 located below the dust cage, and then is fed to a licker-in 3 by a feed roller 5 located below the stripping roller 6. The licker-in 3 normally has a high rotational speed, and impurities adhering to the lint are thrown out to the centrifugal side by centrifugal action and then chopped by the impurity removing knife 4 arranged outside the licker-in 3.

The lint wound on the licker-in 3 is peeled off by the cotton picking plate positioned at the upper side of the left end of the cotton outlet channel 9, and the peeled lint is sucked away along the cotton outlet channel 9 by wind power. The device for providing wind power is called as total cotton collecting and air inducing device in the lint processing machinery, and the air inducing capability of the total cotton collecting and air inducing device can be adjusted according to the actual working condition.

In fig. 1 it can be seen that the licker-in 3 is located in the middle of the tank 2, normally the left side of fig. 1 being referred to as the front side of the lint picker, the right side of fig. 1 being referred to as the rear side of the lint picker, and the direction perpendicular to the paper plane being the left and right sides of the lint picker. In the figure, the licker-in 3 is arranged in the space between the cotton outlet channel 9 and the cotton box 2, in order to avoid movement interference, a gap is required to be reserved between the licker-in 3 with a rotating function and the left and right wall boards, the pressure in the cotton outlet channel 9 is lower than the pressure in the cotton box 2 due to the inevitable air induction of the total cotton collecting and air inducing equipment, so that part of dust and impurities are sucked into the cotton outlet channel 9 through the gap, and the cleaning effect of the lint cotton cleaner is reduced.

At present, no wind shielding measure for shielding wind between the licker-in 3 and the left and right wall boards exists, so that the induced wind adjustment of the cotton collecting induced wind equipment becomes very cautious, the cleaning effect is influenced, and the ginned cotton conveying efficiency is also influenced.

Detailed Description

Since more cotton processing machines rely on pneumatic transport, they often require a relatively closed box, such as the hopper 2 shown in fig. 1, to be constructed. The panels surrounding the box are commonly referred to as wall panels.

In orientation, based on material flow, the cotton processing machine has a defined front and rear, the left side as shown in FIG. 1 being the front side of the lint picker and the right side as shown being the rear side of the lint picker. The direction perpendicular to the paper surface is the left side and the right side of the lint picker.

The lint picker arrangement shown in fig. 1 is a common lint picker arrangement, but not the only one, but in most lint pickers, the two lint pickers 6 for peeling lint picked up by the dust cage 7 are arranged in a substantially vertical relationship with the two feed rollers 5 for feeding down lint picked up by the two lint pickers 6, but the positions thereof are offset in the horizontal direction according to different choices.

The structure that fig. 1 shows is the cotton ginned cotton descaling machine structure of air current brush, is based on the utility model discloses the part of keeping out the wind, the structure of keeping out the wind is applicable to equally based on the cotton ginned cotton descaling machine of brush.

At the front of the cotton box 2, the impurity removing knife 4 removes some impurities wound on the licker-in 3, and the cotton box 2 is led out from the impurity removing plate positioned below the front side of the licker-in 3. The cotton box 2 space in front of the licker-in 3 is a trash discharge space, the sundries fall along the trash plate, and the sundries are prevented from entering the space behind the licker-in 3, especially the cotton outlet channel 9.

The bottom of the cotton box 2 is open at the front side of the impurity board, and an auger can be arranged at the impurity discharging position to discharge the impurities. The auger is not shown in the drawings, but in a preferred embodiment a separate auger or other type of trash removal member is preferably provided to prevent trash from being sucked into the cotton outlet channel 9.

In addition, an air supplement port is left between the lower channel wall plate of the channel wall plates 8 and the licker-in 3, and the air supplement port needs to be isolated from the impurity discharge space.

The lint in the cotton outlet channel 9 is mainly conveyed by wind power and is conveyed by the wind induced by the total cotton collecting and inducing device as a whole, or the lint in the cotton outlet channel 9 is sucked away by suction.

In an embodiment of the present invention, the wind-shielding member is substantially a member for constructing a dynamic seal structure, and wind-shielding does not mean that any leakage cannot be generated.

It is readily understood that the static seal itself is a sub-unit of the sealing grade, and in other words a dynamic seal with a lower sealing capacity than the static seal.

Referring to the description and figures 2 and 3, a wind-sheltering device is shown, the main structure of which is a fan-ring structure, but the use of a ring structure is not excluded.

The wind-sheltering element can be seen in fig. 1 and 4, one on each of the left wall-panel 21 and the right wall-panel 22, in a position aligned with the end of the lickerin roll 3. In the assembled form, if the wind-shielding member is a fan-ring structure as a whole, the axis thereof is coaxial with the licker-in 3. For convenience of description, a basic reference system based on the fan ring structure is adopted no matter whether the wind-shielding component is in the fan ring structure or not.

The wind-shielding member includes:

the base, as the assembly formed by the base plate 11 and the mounting plate 14 in fig. 2, is denoted the base plate 11 as the attachment portion for attachment of the sealing component, and the mounting plate 14 type structure is collectively referred to as the seat portion for mounting of the wind shield component on the wall panel.

A sealing member is further provided for constructing the sealing interface, in other words, in assembled condition, the sealing member should be the part of the wind shield that cooperates with the taker-in cylinder 3, whereby the sealing member needs to be positioned opposite the end of the taker-in cylinder 3 and the seal formed is a dynamic seal.

The sealing member is fixedly mounted on the attachment portion.

In the configuration shown in fig. 2, the wind-shielding member is formed in a fan-ring configuration as a whole, in other words, it is an incomplete configuration with respect to the circular end surface of the licker-in 3. However, in the structure shown in fig. 1, the parts to be blocked, namely the left side and the right side of the inlet of the cotton outlet channel 9, are inevitably larger in overall structure and waste if the circular ring is adopted.

In some embodiments, the attachment portion is an arc plate with a central angle not greater than 180 degrees and not less than 100 degrees, i.e. the base plate 11 shown in fig. 2, and the base plate 11 is an arc steel ring as a whole and is galvanized on the surface.

In the mounted state, the curved base plate 11 is coaxial with the licker-in 3.

In the structure shown in fig. 1, the lower side of the base plate 11 extends to the position of the impurity removing blade 4 positioned at the lowest position, and the upper end extends to the position of the cotton picking plate, so that the central angle of the formed base plate 11 is about 140 degrees, and the base plate can be processed according to 140 degrees during manufacturing.

The substrate 11 may be slightly longer to extend the sealing interface for better sealing. Or may be slightly shorter to reduce the drag of the sealing interface on the lickerin roll 3.

In addition, because of lint cleaning machines of different manufacturers, the angles of the licker-in rollers 3 wound around the inlets of the lint outlet channels 9 are different, and the central angle of the base plate 11 is positively correlated with the angle of the licker-in rollers 3 wound around the inlets of the lint outlet channels 9.

In most applications, the angles of the licker-in 3 surrounded by the cotton outlet channel 9 are not much different, and for this reason, based on the assembling characteristics of the wind-shielding parts on the wall board, namely that the lower end extends to the position of the impurity removing knife 4 positioned at the lowest position, the upper end extends to the position of the cotton picking plate, and the central angle of the matched attachment part is 130-145 degrees.

Generally, the sealing member is often made of a material having a relatively good bending property, such as rubber used for sealing; in some applications, a material with certain rigidity may be selected for manufacturing, such as a teflon plate or a modified teflon plate, and the sealing member made of any material may be directly assembled on the substrate 11 because the substrate 11 provides a base support.

For example, the teflon plate has a certain rigidity, and can be directly mounted on the substrate 11 by screws, and the number of screws is preferably 4 to 8.

In some implementations, the sealing member may be fixed on the substrate 11 by bonding, and the bonding may use metal paste, which has high bonding strength.

For some plate members with certain rigidity, the plate members can be fixed by riveting for example.

In some embodiments the attachment is adapted to ensure that the sealing member, for example of rubber material, maintains a good shape, for which purpose an arcuate pressure plate 13 is provided, the pressure plate 13 being coaxial with the attachment portion, as can be seen in figure 2, the pressure plate 13 pressing against the outer surface of the sealing plate 12, while the base plate 11 supports the inner surface of the sealing plate 12.

In other embodiments, the platen 13 may press against the inner surface of the sealing plate 12, while the base plate 11 supports the outer surface of the sealing plate 12.

Therefore, the pressure plate 13 can press the sealing member against the centrifugal side surface of the attachment portion as well as against the centripetal side surface of the attachment portion. In contrast, the structure in which the pressing plate 13 presses the sealing plate 12 against the centrifugal-side surface of the base plate 11 as shown in fig. 2 is relatively more convenient to assemble.

The substrate 11 and the pressing plate 13 can be made of steel materials, such as stainless steel, or aluminum alloy, and the metal materials have high rigidity and low cost. In this case, when the sealing member is made of rubber, for example, the rubber sealing plate 12 can be maintained in an arc-shaped configuration by clamping the base plate 11 and the pressing plate 13.

The axial end face of the regular arc-shaped structure of the sealing plate 12 is matched with the end face of the licker-in 3, so that better dynamic sealing is easily obtained.

Further, the sealing member protrudes axially outward from the base, avoiding moving interference between the rigid base, such as the base plate 11 shown in fig. 2, and the lickerin roll 3.

The protruding part should not be too long, and should be usually controlled within 5mm, and the longest part should not be more than 10mm, and the too long soft sealing plate 12 is easy to deform and affect the sealing effect.

When the pressing plate 13 is provided, in some embodiments, the structure of the pressing plate 13 on the attachment portion is: the attachment part is provided with a screw hole, the pressing plate 13 is provided with a unthreaded hole in a contraposition mode, and the screw is matched for screw assembly. However, when manufacturing accuracy is ensured, the problem of screw hole positioning is not significant.

In some embodiments, the attachment portion is pre-assembled with a stud, the pressing plate 13 and the sealing member are provided with a light hole in alignment, and the pressing plate 13 is pressed by a nut 17 after the sealing member and the pressing plate are assembled on the attachment portion.

The stud may be welded to the substrate 11, or may be fixed to the substrate 11 by using a metal paste. The base plate 11 may be provided with a screw hole, and the stud may be fixed to the base plate 11 by screwing in advance.

In the configuration shown in fig. 2, the seat portion is a fan ring plate, such as the mounting plate 14 shown in fig. 2, and the mounting plate 14 is integrally formed as a fan ring structure, and the fan ring plate is connected to the end of the attachment portion opposite to the wall plate. In fig. 2, the mounting plate 14 is provided with four circular holes as mounting holes, and the mounting plate 14 is mounted on the corresponding wall plate by using screws.

In addition, an arc-shaped groove is formed in the wall plate in advance, and glue can be filled in the groove to enable the assembling plate 14 to be embedded into the arc-shaped groove to be stuck.

In the configuration shown in fig. 4, the sealing members are mounted on the wall panels to be fitted to the left and right wind-sheltering

structures

1A and 1B shown in fig. 4, and the position of the sealing plate 12 corresponds approximately to the outer diameter of the lickerin roll 3.

Furthermore, when the attachment part is an arc-shaped plate, the wind shielding part is offset at the side of the cotton outlet channel 9 at the position where the wall plate is aligned with the licker-in 3, and the whole structure is relatively compact.

In addition, the inner diameter of the arc-shaped plate is less than or equal to the outer diameter of the plate wrapped by the licker-in 3;

the outer diameter of the arc-shaped structure formed by the sealing part after the sealing part is pressed on the arc-shaped plate is larger than that of the licker-in wrapper plate, and the formed wind-shielding structure 1 still has a good sealing effect under the condition of relative compactness.

In the structure shown in fig. 1, the rear end of the lower channel wall plate constructing the cotton channel 9 is fixed on the rear wall plate of the cotton box, and the front end is installed on the left and right wall plates through the adjusting structure;

an air supplementing opening is reserved between the front end of the lower channel wall plate and the licker-in 3;

the wind-sheltering structure extends at least forwards beyond the air supply opening at the lower side of the licker-in 3.
