Abstract
Description
Technical Field
[0001] This invention relates to a sawtooth cotton cleaning machine. Background Technology
[0002] The saw-tooth cotton cleaning machine is a widely used type of cotton cleaning machine. One type is the gripping saw-tooth cotton cleaning machine. Its basic working principle is that the cotton, propelled by the airflow from the brushes of the ginning machine and drawn in by the dust cage of the cleaning machine, enters the cotton collection section and is adsorbed onto the surface of the dust cage. Dust-laden air passes through the dust cage mesh and enters the interior of the dust cage, exiting through pipes on both sides of the dust cage. The cotton, adhering to the dust cage mesh, rotates with the dust cage to a predetermined position and is then... The cotton is pressed and peeled off by the post-stripping roller and fed downwards to the feed section, thus forming a cotton wadding from the relatively loose cotton and thinning the cotton layer. The cotton fed to the feed section is hooked and combed by the barbs on the licker-in roller and adheres to the roller. The cotton fibers rotate with the licker-in roller at a predetermined angular velocity. Due to the higher specific gravity of large impurities such as infertile seeds, they move to the surface of the licker-in roller under the action of inertial centrifugal force, suspending on the outer layer of the airflow ring of the licker-in roller, and are then impacted and cut by the impurity removal knife, discharged along the surface of the impurity removal knife, and fall into the impurity removal box along the impurity guide plate. The fibers hooked by the licker-in roller are sent into the cotton collection dust cage under the action of airflow.
[0003] Another type of cotton cleaning machine is a pair-roller sawtooth cotton cleaning machine. Its basic working principle is as follows: cotton, propelled by the airflow from the ginning machine or brushing air bag and drawn in by the cleaning machine's fan, is sent through pipes to the dust cage, where it is adsorbed onto the surface. The dust-laden airflow passes through the dust cage mesh and enters the dust cage, exiting through the air ducts on the left and right sides of the dust cage into the dust chamber. The cotton adhering to the dust cage mesh, as the dust cage rotates clockwise, reaches a predetermined position and is peeled off by rollers positioned there, forming a uniform and continuous cotton wadding. This wadding is then evenly hooked and combed by the licker-in rollers. The hooked fibers follow the licker-in rollers in a high-speed circular motion. Due to the higher density of infertile seeds, natural impurities, and large particles, they are discharged under the action of centrifugal force and the obstruction of seven impurity removal blades, and collected and cleaned through the suction pipe. When the hooked fibers encounter the brushes, they are brushed into the cotton lint channel and sent to the cotton collection dust cage for packaging.
[0004] As described above, the sawtooth cotton cleaning machine with a gripping structure has a relatively good cleaning effect. However, it should be noted that cotton cleaning needs to be moderate to avoid over-cleaning. If no cleaning is needed to meet the process requirements, then no treatment is necessary. In other words, the choice of cotton cleaning machine depends on the quality of the raw cotton (seed cotton) and the effectiveness of the cleaning. Under the condition of meeting the cleaning requirements, over-cleaning is unnecessary to avoid problems such as filament lock and fiber breakage. Therefore, the two cotton cleaning methods mentioned above each have their advantages and disadvantages and are suitable for cleaning cotton of different qualities. However, it should be noted that the quality of seed cotton harvested each year is inevitably affected by weather, the timing and dosage of defoliants, etc., resulting in unstable impurity content in the seed cotton. Different cleaning machines will also produce different cleaning effects. In cotton processing plants, the equipment on the cotton processing production line is usually fixed. On the one hand, it is not possible to change the relevant process equipment on the cotton processing production line according to the quality of the incoming cotton; on the other hand, if several different cotton cleaning machines are used in parallel, some cotton cleaning machines will inevitably be idle for a long time, and this will occupy a large amount of plant space. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide a sawtooth cotton cleaning machine that can change 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 cotton cleaning machine is provided, comprising: Chassis; The cleaning assembly is mounted on the chassis and has a licker roller and a lint removal knife assembly located on the first side of the licker roller, as well as a lint output channel located on the second side of the licker roller; the first side and the second side are opposite to each other; the upper edge of the lower wall panel of the cleaning assembly has an upper connecting plate; The cotton collecting section includes a dust cage and a cotton stripping roller located below the dust cage, and the lower edge of the upper wall panel of the cotton collecting section has a lower connecting plate; and The drawing roller assembly has a roller wall plate, which is detachably connected between an upper connecting plate and a lower connecting plate; and a drawing assembly and a cotton feeding assembly are installed on the roller wall plate to draw the cotton wadding conveyed downward by the stripping roller to make it thinner and to feed cotton to the licker-in roller. In this process, after the drafting roller assembly is removed, the cotton collection tube is mounted on the cleaning assembly so that the cotton stripping roller is perfectly matched with the licker-in roller.
[0007] Optionally, the two roller wall panels can be connected as one unit using a crossbeam.
[0008] Optionally, there are two crossbeams, arranged side by side in the vertical direction; and The front and back sides of the two roller wall panels are sealed with cover plates.
[0009] Optionally, the licker-in roller protrudes upward from the lower wall plate of the cleaning assembly by an appropriate distance, such that the lower edge of the feeding assembly of the drafting roller assembly is higher than the lower edge of the roller wall plate.
[0010] Optionally, the upper edge of the lower wall panel is higher than the mounting beam of the topmost debris discharge blade.
[0011] Optionally, the roller sealing assembly configured in the drawing roller assembly is mounted on the roller wall plate in a detachable connection manner.
[0012] Optionally, the connection structure between the support body and the roller wall panel of the roller sealing assembly includes a rotating shaft and at least one adaptable detachable connection structure. After the drawing roller assembly is removed, the roller sealing assembly is flipped up based on the pivot to be higher overall than the lower edge of the roller wall panel.
[0013] Optionally, the upper connecting plate and the lower connecting plate are configured as rectangular flanges corresponding to the wall panel and cover plate to which they are installed.
[0014] Optionally, the drafting assembly includes drafting rollers and drafting rollers opposed in the front-to-back direction; The linear speed of the drafting assembly is greater than that of the stripping roller.
[0015] Optionally, the cotton feeding assembly is located below the drafting assembly to receive the cotton batting pulled and output by the drafting assembly; and the cotton feeding assembly includes: The cotton feeding board is a curved board, which guides the cotton batting from top to bottom tangentially toward the licker-in roller; The feed roller is located on the opposite side of the feed plate and cooperates with the feed plate to guide the cotton wadding tangentially onto the licker-in roller.
[0016] According to embodiments of the present invention, the sawtooth cotton cleaning machine separately constructs the part used for drawing cotton wadding as an assembly, namely the drawing roller assembly. This drawing roller assembly can be optionally installed during use, similar to an accessory for the sawtooth cotton cleaning machine, allowing the decision to install this accessory based on the raw cotton entering the plant. When this accessory is installed, the cotton cleaning capacity is improved, and vice versa. In other words, it has good adaptability to the quality of the processed seed cotton, avoiding both over-cleaning and under-cleaning. Furthermore, it eliminates the need for multiple cotton cleaning machines with different cleaning capacities, saving costs and reducing the space required in the plant. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of a sawtooth cotton cleaning machine with a drawing roller assembly in one embodiment.

Detailed Implementation
[0020] Cotton processing equipment has defined front, back, left, and right sides. Figure 1 In the diagram, the side where cotton import 19 and cotton export 29 are located is the rear side, and the opposite side is the front side. The front-rear direction is also called the longitudinal direction or the length direction.
[0021] With the front and back directions determined, the left and right directions are also determined. The left and right directions are also called the width direction or the lateral direction. The spokes of cotton processing equipment refer to the lateral dimensions of the relevant process components in the equipment.
[0022] The direction perpendicular to the plane defined 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 positional relationships rather than absolute up and down on the same vertical line.
[0023] The cotton processing equipment uses relatively thick steel plate components as mounting bases on both sides; these steel plate components are called wall panels. For example... Figure 1 The dust cage 14, various rollers, waste removal knife 4, and piercing roller 5 shown all use wall panels as the mounting base.
[0024] Since cotton processing equipment mainly relies on wind power for material transportation, the wall panels serve as supports and also constitute closed components on the left and right sides. In the front and back directions, sheet metal is mainly used to make shielding components such as the dust cage front cover 13. The strength and rigidity requirements for these components are much lower than those for the wall panels. For example, the dust cage front cover 13 is not used for load-bearing, but mainly for constructing the chamber.
[0025] The main structure of the saw-tooth cotton cleaning machine according to the embodiments of the present invention is basically the same as that of the conventional saw-tooth cotton cleaning machine. The main difference is that the drafting roller assembly is configured as an accessory and can be optionally installed. The rest of the parts can be used as in the conventional saw-tooth cotton cleaning machine. For ease of description, the term "accessory" will be used to refer to the drafting roller assembly in the following text, unless otherwise directly related.
[0026] Furthermore, it should be understood that the cooperation relationship between, for example, the front peeling roller 12 and the rear peeling roller 21, and their cooperation relationship with the dust cage 14 are fixed, regardless of the presence of the aforementioned attachments.
[0027] Figure 1 and Figure 2 In this diagram, chassis 2 serves as the mounting base for the wall panels. Chassis 2 typically uses shaped steel as its frame, as shown in the diagram as channel steel. Furthermore, chassis 2 generally needs to be supported to a certain height. Figure 1 and Figure 2 The chassis 2 is supported to a certain height using support legs 1.
[0028] Compared to the other two parts, the cleaning assembly is relatively statically configured in the embodiments of the present invention. The other two parts, namely the accessories and the cotton collection unit, need to be reconfigured when adjustments are made. The accessories can be selected according to the quality of the raw cotton entering the station, and after the accessories are adjusted, the cotton collection unit needs to be lowered or raised to a predetermined height.
[0029] The wall panel of the cleaning assembly is referred to as the lower wall panel, and it is directly fixed to the chassis 2. The lower wall panel generally includes... Figure 1 and Figure 2 The dust grid wall panel 3 and the rack wall panel 31 shown are used to construct different functional areas, which is common knowledge in the field and will not be described in detail here.
[0030] Figure 1 and Figure 2 In the cleaning assembly, there is a spiked roller 5, and a set of debris removal knives 4 are provided on the front side of the spiked roller 5. The number of debris removal knives 4 is generally around seven, but usually no less than five, but usually no more than nine.
[0031] The accessory adapted to the embodiments of the present invention allows for adjustment of the upward arrangement of the debris removal blades 4. Figure 1 As can be seen, the upper surface of the mounting beam of the topmost dust removal blade 4 is basically horizontal, and the mounting beam does not extend beyond the upper edge of the dust grid wall panel 3. In other words, the mounting beam of the dust removal blade 4 is fixed on the lower wall panel, and the fixed position does not interfere with the roller wall panel 8.
[0032] The front side of the licker-in roller 5 is the cotton output channel, and its configuration is also a standard configuration in this field. Figure 1 and Figure 2 The details are very clear in the text, so I will not repeat them here.
[0033] Additionally, regarding the Roller sealing assembly 27... Figure 1The image shows the roller sealing assembly 27 partially located on the frame wall panel 31 and partially on the roller wall panel 8. In practice, it can be fixed only to the roller wall panel 8, with its outward extension covering part of the frame wall panel 31. Additionally, in some embodiments, the roller sealing assembly 27 can also be connected to the frame wall panel 31. This connection serves as an auxiliary connection and can be a quick-release method, such as a pin connection. This allows the connecting pin to be removed from the outside when assembling or disassembling accessories, and then reattached after the accessory is secured in place.
[0034] To facilitate the storage of accessories, the roller seal assembly 27 can be removed or partially removed after the accessories are removed. For example, the roller seal assembly 27 can use the pivot as the basic positioning and connection part. After removing the other connecting parts, the roller seal assembly 27 can swing around the pivot. Just make sure that the roller seal assembly 27 does not interfere with the ground after the accessories are laid flat.
[0035] In addition, for easy disassembly and assembly, a hanging structure such as a hanging ring can be installed on the outer surface of the roller wall panel 8.
[0036] Correspondingly, in Figure 2 In the illustrated structure, an ear plate suitable for hanging is also provided on the upper side of the upper wall panel 11, as shown in the lifting assembly 15.
[0037] Given that the cotton output channel located behind the licker-in roller 5 and its configuration are irrelevant to the main inventive point of this invention, and are a conventional configuration in the art, and in Figure 1 and Figure 2 The details are clearly shown in the image, so I will not repeat them here.
[0038] The part of the cleaning assembly related to the accessories is that the upper edge of the lower wall panel of 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 by means of welding, for example. The strip has openings to facilitate connection with bolts.
[0039] Accordingly, the upper part of the sawtooth cotton cleaning machine is a cotton collecting section, used to collect the cotton lint conveyed through cotton conveying pipes or other cotton conveying methods onto the mesh surface of the dust cage 14 to form a cotton wadding with a predetermined thickness. Therefore, the cotton collecting section has a dust cage 14. At the same time, in order to peel off the cotton wadding from the dust cage 14, specialized components are required, mainly cotton peeling rollers, such as… Figure 1 The front stripping roller 12 and the rear stripping roller 21 shown can be used to directly send the stripped cotton lint for cleaning, or they can be stretched to a certain extent to make the cotton lint thinner before cleaning, so that the impurities are easier to remove.
[0040] The cotton collecting section has an upper wall panel, and the lower edge of the upper wall panel of the cotton collecting section has a lower connecting plate. The configuration of the lower connecting plate can be referred to the upper connecting plate as described above, and will not be repeated here.
[0041] As previously described, the stretching roller assembly is configured as an accessory having a roller wall plate 8, which is adapted to the upper and lower connecting plates and is fitted with corresponding roller wall plate connecting plates, and has aligning holes for assembly of the accessory on the sawtooth cotton cleaning machine using, for example, bolt connections.
[0042] As an accessory, the roller wall panel 8 is equipped with a drafting assembly and a cotton feeding assembly. The drafting assembly further drafts the cotton batting conveyed from the cotton collecting section, making it thinner. The cotton feeding assembly then feeds the thinned cotton batting to the licker-in roller 5 in a roughly horizontal manner. The roughly horizontal manner is mainly for structural adaptation when the drafting roller assembly is used as an accessory, so that the lower edges of the components within the drafting roller assembly are higher than the lower edge of the roller wall panel 8, which facilitates the storage of accessories.
[0043] contrast Figure 1 and Figure 2 After the drafting roller assembly is removed, the cotton collection tube is mounted on the cleaning assembly so that the cotton stripping roller is perfectly matched with the licker-in roller 5.
[0044] As mentioned earlier, for the drawing roller assembly, the front and rear sides of its roller wall panel 8 are generally connected. In addition to the sheet metal body, beams can also be installed, such as... Figure 1 The crossbeam 23 shown is used to ensure the stability of the overall structure of the accessory.
[0045] exist Figure 1 In the middle, there are two crossbeams 23, which are arranged side by side in the vertical direction 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 not only ensure the seal, but also increase the connection strength.
[0046] In addition, the upper and lower edges of the cover plate are also constructed with roller wall plate connecting plates between the cotton collection section and the cleaning assembly, thereby forming a rectangular flange structure in conjunction with the roller wall plate connecting plates at the wall plate.
[0047] exist Figure 1 and Figure 2 In the illustrated structure, the licker roller 5 protrudes upward from the lower wall plate of the cleaning assembly by an appropriate distance, so that the lower edge of the feeding assembly of the drafting roller assembly is higher than the lower edge of the roller wall plate, so as to avoid interference between the feeding assembly and the ground when the accessories are stored.
[0048] Similarly, as mentioned earlier, the upper edge of the lower wall panel is higher than the mounting beam of the topmost debris discharge blade 4, which is still intended to take into account the problem of interference between the internal components of the accessory and the ground when it is stored separately.
[0049] Regarding the question of how to stretch the cotton wadding in the appendix, it is mainly achieved by the difference in rotational speed. Specifically, the stretching assembly includes a stretching light roller 9 and a stretching roller 25 that are opposed in the front-to-back direction. The linear speed of the stretching assembly is greater than that of the stripping roller. During this process, because the linear speed of the stretching assembly is greater than that of the feeding speed of the stripping roller, the cotton wadding will be stretched, making it longer and thinner, which is beneficial for cleaning.
[0050] In addition, Figure 1 In the illustrated structure, the cotton feeding assembly is located below the drafting assembly to receive the cotton batting that has been drawn and output by the drafting assembly; and the cotton feeding assembly includes: The cotton feeding plate 6 is a curved plate to guide the cotton batting from top to bottom tangentially towards the licker roller 5; The cotton feed roller 26 is located on the opposite side of the cotton feed plate 6 and cooperates with the cotton feed plate 6 to guide the cotton wadding tangentially onto the licker roller 5.
