Description

Technical Field

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

[0002] Sawtooth lint cleaning machine is a widely used lint cleaning machine. One of the lint cleaning machines is a grip-structure sawtooth lint cleaning machine. Its basic working principle is that lint enters the cotton collecting part of the lint cleaning machine under the blowing of the brush airflow of the cotton gin and the attraction of the dust cage of the lint cleaning machine, and is adsorbed on the surface of the dust cage. The dust-laden air passes through the dust cage mesh surface into the dust cage and is discharged from the pipes on both sides of the dust cage. The lint adheres to the dust cage mesh surface and rotates with the dust cage to a predetermined position, such as the front The rear stripping rollers press and strip the cotton, feeding it downward to the feeding section, thereby forming a relatively loose lint batt and thinning the cotton layer. The cotton fed by the feeding section is hooked and combed by the spikes on the licker-in roller and adheres to the licker-in roller. The cotton fibers rotate with the licker-in roller at a predetermined angular velocity. Due to the high specific gravity of large impurities such as sterile seeds, they move to the licker-in roller surface under the action of inertial centrifugal force and float on the outer layer of the licker-in roller airflow circle. They are then impacted and cut by the trash removal knife, discharged along the surface of the trash removal knife, and fall into the trash removal box along the trash plate. The fibers pulled by the licker-in roller hook are sent to the main cotton dust cage under the action of airflow.

[0003] Another type of lint cleaning machine features a pair of rollers with sawtooth lint cleaning mechanisms. Its basic operating principle is that lint, driven by air from a cotton gin or brush bag and drawn by the lint cleaning machine's fan, is transported through a pipe to a dust basket, where it is adsorbed by the basket's surface. The dust-laden air flows through the basket's mesh surface and enters the basket, where it is discharged into the dust chamber through ducts on its left and right sides. The lint clinging to the basket's mesh surface rotates clockwise until it reaches a predetermined position, where it is removed by rollers positioned there, forming a uniform, continuous mat. This mat is then evenly combed by licker-in rollers. The fibers pulled by the hooks follow the licker-in rollers in a high-speed circular motion. Due to the high weight of defects such as sterile seeds, natural impurities, and large particles, they are discharged by centrifugal force and blocked by seven debris removal blades, where they are collected and cleaned through a dust collection duct. When the pulled fibers encounter a brush, they are brushed into the lint duct and sent to a collection basket for packaging.

[0004] As can be seen from the above description, the gripping sawtooth lint cleaner achieves relatively good cleaning results. However, it should also be noted that lint cleaning should be moderate, avoiding excessive cleaning. If the process requirements can be met without cleaning, then no treatment is necessary. In other words, the type of lint cleaner to use depends on the quality of the raw cotton (seed cotton) and the effectiveness of the seed cotton cleaning. If the cleaning requirements are met, excessive cleaning is not necessary to avoid problems such as thread locking and fiber breakage. Therefore, the above two lint cleaning methods have their own advantages and disadvantages and are suitable for cleaning lint of different qualities. However, it should be noted that the quality of the seed cotton harvested each year is inevitably affected by factors such as weather, the timing and dosage of defoliant application, and the impurity content of the seed cotton is unstable, resulting in varying cleaning results using different cleaning machines. At cotton processing plants, the equipment on the cotton processing line is typically fixed. On the one hand, it is not possible to adjust the relevant process equipment based on the quality of the incoming cotton. On the other hand, using several different lint cleaning machines in parallel would inevitably cause some of the cotton cleaning machines to remain idle for long periods of time and occupy a large area of ​​the plant. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a sawtooth lint cleaning machine capable of converting the cleaning structure, thereby having better adaptability to the quality of the processed seed cotton.

[0006] According to an embodiment of the present invention, a sawtooth lint cleaning machine is provided, comprising:

[0007] chassis;

[0008] A cleaning assembly is mounted on the chassis and comprises a licker-in roller and a debris removal knife group located on a first side of the licker-in roller, and a lint output channel located on a second side of the licker-in roller; the first side is opposite to the second side; the upper edge of the lower wall panel equipped with the cleaning assembly has an upper connecting plate;

[0010] The drafting roller assembly comprises a roller wall panel, which is detachably connected between the upper connecting plate and the lower connecting plate; and a drafting assembly and a cotton feeding assembly are mounted on the roller wall panel to draw the cotton batt conveyed downward by the stripping roller to thin it and feed the cotton to the licker-in roller;

[0011] Wherein, after the drafting roller assembly is dismantled, the cotton collecting unit is mounted on the cleaning assembly so that the cotton stripping roller is exactly matched with the licker-in roller.

[0025] The feeding roller is located on the opposite side of the feeding plate and cooperates with the feeding plate to guide the cotton batt to the licker-in roller in a tangential manner.

DETAILED DESCRIPTION

[0030] Cotton processing equipment has definite front, back, left, and right. Figure 1 In the figure, the side where the lint inlet 19 and the lint outlet 29 are located is the rear side, and the side opposite thereto is the front side. The front-to-back direction is also called the longitudinal direction or the length direction.

[0031] Under the condition that the front and back are determined, the left and right are also determined. The left and right directions are also called width and transverse directions. The spokes of cotton processing equipment refer to the transverse dimensions of related process components in the process equipment.

[0032] The direction perpendicular to the plane determined by front, back, left and right is called the up and down direction. The up and down direction is also called the vertical direction. However, in more cases, up and down are used to indicate the positional relationship, rather than the absolute up and down on the same plumb line.

[0033] The two sides of the cotton processing equipment use relatively thick steel plate components as the installation base, which are called wall panels. Figure 1 The dust cage 14, various rollers, debris removal knife 4 and licker-in roller 5 shown in the figure all use the wallboard as the installation base.

[0034] Since cotton processing equipment mainly relies on wind power to transport materials, the wall panels serve as supports and also constitute the closed parts on the left and right sides. Sheet metal is mainly used to make shielding parts in the front and rear directions, such as the front cover 13 of the dust cage, and the strength and rigidity requirements for them are much lower than those of wall panels. For example, the front cover 13 of the dust cage is not used to bear weight, but is mainly used to construct the chamber.

[0035] The main structure of the sawtooth lint cleaning machine according to the present invention is essentially the same as that of a conventional sawtooth lint cleaning machine, with the main difference being that the drafting roller assembly is configured as an optional accessory. The remaining components can be used with conventional sawtooth lint cleaning machines. For ease of description, the term "accessory" will be used to refer to the drafting roller assembly unless otherwise directly relevant.

[0036] In addition, it should be understood that, for example, the cooperation relationship between the front stripping roller 12 and the rear stripping roller 21, and the cooperation relationship between the front stripping roller 12 and the rear stripping roller 21 and the dust cage 14 is determined regardless of whether the accessories are present.

[0037] Figure 1 and Figure 2 In the figure, the chassis 2 is the mounting base of the wall panel. The chassis 2 is generally made of steel as the skeleton, such as the channel steel shown in the figure. And it is generally necessary to support the chassis 2 to a certain height. Figure 1 and Figure 2 The support legs 1 are used to support the chassis 2 to a certain height.

[0038] Compared with the other two parts, the cleaning assembly is relatively statically arranged in the embodiment of the present invention, and the other two parts, namely the accessories and the cotton collecting part, need to be reconfigured when adjusted. The accessories can be selected according to the quality of the raw cotton entering the station, and after the accessories are adjusted, the cotton collecting part needs to be dropped off the frame or raised to a predetermined height.

[0039] The wall panel of the cleaning assembly is recorded as the lower wall panel, which is directly fixed on the chassis 2. The lower wall panel generally includes Figure 1 and Figure 2 The dust grid wall panels 3 and the rack wall panels 31 shown in the figure are used to construct different functional areas respectively. This is common knowledge in the field and will not be described in detail here.

[0040] Figure 1 and Figure 2 In the embodiment, the cleaning assembly comprises a licker-in roller 5, and a group of debris removal knives 4 are provided at the front side of the licker-in roller 5. The number of the debris removal knives 4 is generally about seven, but usually not less than five, and usually not more than nine.

[0041] The attachment adapted to the embodiment of the present invention can adjust the arrangement of the debris removal knife 4 upwards. Figure 1 It can be seen that the upper surface of the mounting beam of the topmost debris removal knife 4 is basically horizontal, and the mounting beam does not exceed the upper edge of the dust grid wall panel 3, or the mounting beam of the debris removal knife 4 is fixed on the lower wall panel, and the fixed position does not interfere with the roller wall panel 8.

[0042] The front side of the licker-in roller 5 is the lint output channel, and its configuration is also a conventional configuration in this field. Figure 1 and Figure 2 It is also shown very clearly in the text, so I will not repeat it here.

[0043] In addition, regarding the roller sealing assembly 27 Figure 1 Although shown as being partially located on the frame wall panel 31 and partially located on the roller wall panel 8, it may actually be fixed only to the roller wall panel 8, and its outwardly extending portion may cover a portion of the frame wall panel 31. In addition, in some embodiments, the roller sealing assembly 27 may also be connected to the frame wall panel 31, and the connection with the frame wall panel 31 serves as an auxiliary connection, and may adopt a quick-release connection method, such as a pin connection, so that when removing or installing an accessory, the connecting pin can be removed from the outside, for example, and when installing the accessory, the connecting pin can be inserted after the accessory is fixed in place.

[0044] In order to facilitate the storage of accessories, the roller sealing assembly 27 can be removed, or partially removed after the accessories are removed. For example, the roller sealing assembly 27 can use the rotating shaft as the basic positioning and connection part. After removing the remaining connecting parts, the roller sealing assembly 27 can swing around the rotating shaft. It is only necessary to ensure that the roller sealing assembly 27 does not interfere with the ground after the accessories are laid flat.

[0045] In addition, in order to facilitate disassembly and assembly, a structure suitable for hanging, such as a hanging ring, may be provided on the outer surface of the roller wall panel 8.

[0046] Correspondingly, in Figure 2 In the illustrated structure, ear plates suitable for hanging are also provided on the upper side of the upper wall panel 11, such as the hanging assembly 15 shown in the figure.

[0047] Since the lint output channel and its configuration at the rear side of the licker-in roller 5 are irrelevant to the main invention of the embodiment of the utility model, they belong to the conventional configuration in the field, and Figure 1 and Figure 2 It is clearly shown in the figure, so I will not go into details here.

[0048] The part of the cleaning assembly related to the accessories is that the upper edge of the lower wall panel equipped with the cleaning assembly has an upper connecting plate. The upper connecting plate is mainly formed into a flanged strip on the upper edge of the lower wall panel using methods such as welding, and holes are opened on the strip to facilitate connection with bolts.

[0049] Accordingly, the upper part of the sawtooth lint cleaning machine is a cotton collecting part, which is used to collect the lint conveyed through the cotton conveying pipe or other cotton conveying methods on the mesh surface of the dust cage 14 to form a cotton batt with a predetermined thickness. Therefore, the cotton collecting part has a dust cage 14. At the same time, in order to peel off the cotton batt on the dust cage 14, special components need to be configured, mainly cotton stripping rollers, such as Figure 1As shown in the figure, the front stripping roller 12 and the rear stripping roller 21, the stripped lint can be sent directly for cleaning, or it can be pulled to a certain extent to make the cotton batting thinner before cleaning, so that the debris is easier to be cleaned.

[0050] The cotton collecting part has an upper wall plate, and the lower edge of the upper wall plate equipped with the cotton collecting part has a lower connecting plate. The configuration of the lower connecting plate can refer to the upper connecting plate described above, and will not be repeated here.

[0051] As mentioned above, the stretching roller assembly is configured as an accessory and has a roller wall panel 8. The roller wall panel 8 is adapted to the upper connecting plate and the lower connecting plate and is adapted to be equipped with corresponding roller wall panel connecting plates, and holes are opened in position to assemble the accessory on the sawtooth lint cleaning machine using, for example, a bolt connection method.

[0052] As an accessory, the roller wall panel 8 is equipped with a drafting assembly and a feeding assembly. The drafting assembly further drafts the batt delivered from the cotton collecting section to reduce its thickness, while the feeding assembly feeds the thinned batt to the licker-in 5 in a roughly horizontal manner. The roughly horizontal manner is adopted here mainly to ensure the structural adaptability of the drafting roller assembly as an accessory, so that the lower edges of the components in the drafting roller assembly are higher than the lower edge of the roller wall panel 8, which is convenient for the storage of accessories.

[0053] contrast Figure 1 and Figure 2 After the drafting roller assembly is dismantled, the cotton collecting unit is mounted on the cleaning assembly so that the stripping roller fits exactly with the licker-in roller 5.

[0054] As mentioned above, for the drafting roller assembly, the front and rear sides of the roller wall panel 8 are generally connected. In addition to the sheet metal body, a beam body can also be set, such as Figure 1 The crossbeam 23 shown in FIG. 1 is provided to ensure the stability of the overall structure of the accessory.

[0055] exist Figure 1 There are two crossbeams 23, which are arranged in parallel in the upper and lower directions to improve the overall structural stability; and the front and rear sides of the two roller wall panels 8 are sealed with cover plates, which can increase the connection strength to a certain extent while ensuring sealing.

[0056] In addition, the upper and lower edges of the cover plate are also constructed to form connecting plates for the roller wall panels between the cotton collecting part and the cleaning assembly, thereby cooperating with the roller wall panel connecting plates at the wall panel to form a rectangular flange structure.

[0057] exist Figure 1 and Figure 2In the illustrated structure, the licker-in roller 5 is exposed upward from the lower wall panel of the cleaning assembly by an appropriate distance so that the lower edge of the cotton feeding assembly of the drafting roller assembly is higher than the lower edge of the roller wall panel, so as to avoid interference between the cotton feeding assembly and the ground when the accessories are stored.

[0058] Likewise, as mentioned above, the upper edge of the lower wall panel is higher than the mounting beam of the uppermost debris removal knife 4, and the purpose is still to take into account the problem of interference between the internal components of the accessory and the ground when it is stored separately.

[0059] Regarding the question of how to stretch the cotton batt in the attachment, it is mainly achieved by the speed difference. Specifically, the stretching assembly includes a stretching light roller 9 and a stretching roller 25 opposite to each other in the front and rear directions; the linear speed of the stretching assembly is greater than the linear speed of the cotton stripping roller. In this process, since the linear speed of the stretching assembly is large and higher than the feeding speed of the cotton stripping roller, the cotton batt will be stretched, and it will be stretched and thinned, which is conducive to cleaning.

[0060] In addition, Figure 1 The illustrated structure further includes a cotton feeding assembly located below the drafting assembly to receive the cotton batt drawn and output by the drafting assembly; and the cotton feeding assembly includes:

[0061] The cotton feeding plate 6 is a curved plate to guide the cotton batt from the top to the tangential direction of the licker-in roller 5;

[0062] The feeding roller 26 is located on the opposite side of the feeding plate 6 and cooperates with the feeding plate 6 to guide the cotton batting to the licker-in roller 5 in a tangential manner.
