Description

Technical Field

[0001] The present invention relates to an auxiliary cotton feeding device for auxiliary cotton feeding of a cotton baler, and also relates to a cotton feeding system equipped with the auxiliary cotton feeding device. Background Art

[0002] In the domestic cotton processing sector, rising labor and processing costs, coupled with volatile lint prices, have led to an increasingly urgent demand for high-speed balers. This rapid baling also places higher demands on the baler's loading system. While some currently available cotton balers qualify as high-speed balers, these simply speed up various processes, resulting in less than ideal results.

[0003] The main reason why the effect is not ideal is that in the cotton feeding process on the pre-pressing side of the baler, the cotton feeding and pre-pressing need to always maintain a rhythmic linkage, which makes the forward and backward speeds of the cotton feeding trolley located between the cotton flow path and the pre-pressing side cotton box adaptively improved under the condition of the overall speed increase of the baler. The cotton flow path is generally an inclined chute structure. For example, the lint cotton after ginning or the loose cotton after cleaning is transported to the inlet end of the cotton flow path through a conveying pipe. After the lint cotton enters the cotton flow path from the inlet end of the cotton flow path, it slides freely down along the bottom plate of the cotton flow path with a chute structure by gravity and is transported to, for example, the front box body of the cotton feeding trolley. Then the cotton feeding trolley pushes the lint cotton delivered to its front side forward, and pushes the lint cotton that has been delivered to the front box body of the cotton feeding trolley into the pre-pressing side cotton box. After that, the cotton feeding trolley is reset, and the pre-pressing side cotton stepping device pre-presses the lint cotton currently delivered to the pre-pressing side cotton box. The reset cotton feeding trolley further pushes the currently in place lint into the pre-pressing side cotton box, and this is repeated several times until the amount of lint in the pre-pressing side cotton box reaches a predetermined amount.

[0004] Compared with the traditional baler cotton feeding system, although the movement speed and frequency of the cotton feeding trolley have increased significantly, the speed at which the lint cotton slides down due to gravity is constant, resulting in no substantial increase in the total cotton feeding volume.

[0005] In addition, if one attempts to increase the cotton storage capacity at the end of the cotton flow path while speeding up the cotton feeding, the thickness of the cotton batt will increase significantly, and the cotton feeding trolley will frequently fail to cut the cotton batt, causing the equipment to jam.

[0006] In addition, there is a significant defect in some implementations: when there is too much cotton accumulated in the cotton flow channel, after the baler transfers the box, the cotton delivery link will frequently encounter problems such as the cotton delivery cart getting stuck due to the large amount of cotton. The methods for dealing with such jamming problems are often extremely cumbersome.

[0007] It can be seen that how to increase the cotton feeding speed while appropriately increasing the amount of cotton fed in a single time, and effectively avoid the problem of cotton feeding being stuck due to the sudden feeding of excessive lint, has become the core bottleneck restricting the speed of cotton baling machines.

[0008] It should be noted that the above-mentioned background technology is the technical information mastered by the inventor in order to deduce the relevant technical problems or obtained in the process of designing the present invention, and does not mean that the above-mentioned background technology has been the existing technology before the application of the present invention, especially the technical content of the recognition and confirmation of the relevant technical problems. Summary of the Invention

[0009] The object of the present invention is to provide an auxiliary cotton feeding device for a cotton baler, which is suitable for improving the cotton feeding speed of the cotton baler and is not prone to causing cotton feeding jams. The present invention also provides a cotton feeding system equipped with the auxiliary cotton feeding device for the cotton baler.

[0010] According to a first aspect of an embodiment of the present invention, there is provided an auxiliary cotton feeding device for a cotton baler, comprising: The shell has left and right wall panels that are opposite to each other. The lower conveying part is installed at the lower part of the left and right wall panels and is used to construct the lower part of the channel; The upper conveying part is installed at the lower part of the left and right wall panels, and is used to construct the lower part of the channel, and determines the channel together with the left and right wall panels and the lower conveying part; The driving mechanism is used for driving the upper conveying part and the lower conveying part.

[0011] Optionally, the lower conveying part is a roller bed or a conveyor belt mechanism.

[0012] Optionally, if the lower conveying part is a roller bed, the gap between the roller shafts on the roller bed is not greater than 10 mm.

[0013] Optionally, the last roller of the roller bed is a smooth roller and / or a guide plate is provided on the rear side of the last roller; Correspondingly, when a guide plate is provided, the gap between the feed end of the guide plate and the last roller is not greater than 4 mm.

[0014] Optionally, the roller shaft on the roller bed is a rubber-coated grooved roller.

[0015] Optionally, the number of rollers on the roller bed is 2 to 10.

[0016] Optionally, the upper conveying part is an upper roller, the number of the upper rollers is 1 to 3, and the upper rollers are toothed rollers or spiked rollers.

[0017] Optionally, when the upper roller is a toothed roller, the extending direction of the teeth is the axial direction of the upper roller, and the number of teeth is 6 to 24, and the tooth height is 18 mm to 36 mm.

[0018] Optionally, the distance between the upper conveying part and the lower conveying part is 74 mm to 474 mm.

[0019] Optionally, the angle between the conveying direction determined by the lower conveying part and the horizontal plane is 15° to 60° obliquely downward.

[0020] Optionally, the upper conveying part and the lower conveying part share the same power machine.

[0021] According to a second aspect of an embodiment of the present invention, a cotton feeding system is provided, comprising: The cotton flow channel is tilted and is used to receive the lint cotton delivered by the upper cotton processing equipment; The auxiliary cotton feeding device of the cotton baler described in the first aspect of the embodiment of the present invention is arranged at the lower end of the cotton flowing channel.

[0022] A cotton feeding system for a baler utilizes an inclined cotton chute to allow lint to slide down by gravity. Lint is then pushed into a pre-pressing cotton box on the baler's side by, for example, a cotton trolley. In an embodiment of the present invention, an auxiliary cotton feeding device for the cotton baler is provided. This device is located on the discharge side of the chute. When the upper and lower conveyor sections stop operating, lint transported from the chute accumulates within the baler's auxiliary feeding device's channel. When more lint is delivered, some lint accumulates behind the channel. When, for example, the trolley returns, the auxiliary cotton feeding device activates, enabling faster feeding through the upper and lower conveyor sections. During this process, because the lint can be temporarily stored within the chute or possibly behind the baler's auxiliary feeding device, it does not interfere with the trolley's cotton delivery, nor does it cause the trolley to become stuck due to lint accumulation. Furthermore, the temporary storage volume achieved in this manner, corresponding to the volume adapted to the temporary storage, helps increase the feeding speed of the chute. After the cotton feeding trolley is reset, the aforementioned pinching and feeding can be used to achieve rapid feeding, thereby shortening the cotton feeding cycle of the cotton feeding trolley, and thus overall improving the feeding speed of the baler. At the same time, it should be noted that the lint transported by the cotton trough is relatively fluffy. Based on the aforementioned pinching and feeding, the relatively fluffy lint can be initially compressed, for example, resulting in a relatively increased weight of cotton delivered by the cotton feeding trolley each time, which is also relatively beneficial to the speed of the baler.

[0033] It should be noted that in cotton processing lines, there is a defined flow order between upstream and downstream process equipment. The equipment that processes the cotton first is typically referred to as the upstream process equipment, while the equipment that processes the cotton first is referred to as the downstream process equipment. However, for cotton transportation, the forward direction is typically considered the target direction, while the reverse direction is considered the backward direction. While the two methods determine the forward and backward directions in opposite directions, this does not create ambiguity, even if the two reference frames exist simultaneously.

[0034] In the embodiment of the present invention, the front and back determined by the conveying direction are mainly used as the main reference system. After the front and back are determined, the left and right are determined, and after the front, back, left and right are determined, the up and down are also determined.

[0035] The front-to-back direction is also called the longitudinal direction, length direction, and head-to-tail direction, while the left-to-right direction is also called the transverse direction and width direction, and the left-to-right direction also corresponds to the width.

[0036] Figure 1 FIG. 1 is a schematic diagram of an installation state of an auxiliary cotton feeding device 4 of a cotton baler on a cotton feeding system according to an embodiment of the present invention. Figure 1 In the cotton baler, the auxiliary cotton feeding device 4 is arranged at the lower end of the cotton flow channel 2, that is, the discharge end. The feeding end of the cotton flow channel 2 is the cotton collector 1, and the preceding process equipment of the cotton collector 1 can be a cotton gin or other process equipment. And as mentioned in the background technology part, the lint cotton packed by the baler can be lint cotton after ginning or loose cotton after cleaning. It can be seen from this that Figure 1 The illustrated structure is only one application scenario, not the only application scenario.

[0037] Figure 1 In the illustrated configuration, the lint discharged from the accumulator 1 cannot guarantee a uniform or continuous layer of lint. In other applications, the accumulator itself is used for baling loose cotton. Therefore, for example, the amount of lint flowing from the accumulator 2 per unit time is not stable. Therefore, the weight of the baled cotton bales is usually controlled on the pre-loading side, rather than the feeding side.

[0038] As mentioned above, the cotton flow rate per unit time of the cotton flow channel 2 is unstable. Figure 1 The feeding rhythm of the cotton feeding section 5 shown in the figure is often relatively fixed, which results in an unstable amount of cotton fed in each action of the cotton feeding section 5. The lint cotton that naturally flows due to gravity is relatively fluffy, and the cotton fed by the cotton feeding section 5 to the pre-pressing side of the baler is also relatively fluffy. The weight of the lint cotton per unit volume is relatively small, and the overall cotton feeding efficiency is relatively low.

[0039] In the embodiment of the present invention, taking advantage of the relatively poor fluidity of lint itself, the lint is fed by means of the cooperation of the upper conveying part and the lower conveying part. When the feeding is stopped, the upper roller and the lower conveying part stop moving or feed the cotton at a relatively low speed. In this process, the lint is compressed based on the forced feeding, so that the lint from, for example, Figure 2 The lint discharged from the cotton feeding channel 13 is relatively denser than the lint discharged from the cotton flowing channel 2, and the weight of the lint per unit volume is relatively greater. On the one hand, the number of times the baler steps on the cotton on the pre-pressing side can be reduced. On the other hand, under the condition of the same number of bales of the baler, the number of reciprocating movements of the cotton feeding trolley of the cotton feeding section 5 can be relatively reduced. In this way, under the condition of the same number of reciprocating movements of the cotton feeding trolley per unit time, the baler can produce relatively more bales per hour.

[0040] Furthermore, for example, when the cotton gin and the cotton collector 1 are accelerated, the total cotton flow rate of the cotton flow channel 2 increases, and when used in conjunction with, for example Figure 2 The auxiliary cotton feeding device 4 of the cotton baler shown performs auxiliary cotton feeding to make the cotton flowing and feeding rhythm more coordinated, thereby assisting in improving the baling speed of the baler as a whole.

[0041] exist Figures 2-4 、 Figure 8 and Figure 9 In the illustrated structure, the auxiliary feeding device 4 of the cotton baler includes a portion serving as a body, which is referred to as a shell. The shell includes at least left and right wall panels. Figure 2 They are collectively referred to as wall panels 11.

[0042] The wall panel 11 is mainly used as a mounting base for roller sets, and is also a structure for constructing Figure 2 Components of the left and right side walls of the cotton feeding channel 13.

[0043] Since it is used as a mounting base for a roller group, for example, its own strength and rigidity requirements are relatively high, so the main body of the wall panel 11 is mainly made of steel plate, and the outer surface of the main body of the wall panel 11 is also connected to the reinforcing plate 19 by welding, for example.

[0044] For example Figure 2 and Figure 3 In the figure, the housing has a front flange 7 and a rear flange 20. The front flange 7 and the rear flange 20 are frame structures, wherein the front flange 7 is used for connecting the housing with, for example, Figure 1 The rear flange 20 is used for connecting the cotton feeding part 5 in the housing, for example Figure 1 The connection between the cotton storage hopper 3 can also be used with Figure 1 Direct connection to the cotton channel 2.

[0045] The components of the auxiliary cotton feeding device for non-cotton balers, such as the cotton storage hopper 3, described in the embodiments of the present invention are components of related cotton feeding systems known to the inventors and do not represent the components of existing cotton feeding systems. Furthermore, in the embodiments of the present invention, the description focuses on the auxiliary cotton feeding device for cotton balers. Other components of the cotton feeding system, including how to control the start and stop of the upper roller and lower conveyor, belong to the use or control method rather than the mechanical components. Therefore, only the auxiliary mechanical components are described here, and no detailed description is given.

[0046] The horizontal connection part in the front flange 7 and the rear flange 20 of the frame structure is also used to connect the left and right wall panels. Figure 2 and Figure 3 The top plate 14 in the wall panel can be provided or not, and it is preferred to provide the top plate 14. The top plate 14 is also used for connecting the left and right wall panels.

[0047] In addition, regarding the housing, in e.g. Figures 2-4 、 Figure 8 and Figure 9 It is not separately marked whether there is a bottom plate, but the inventor believes that the bottom plate may be provided or not, and it is preferred not to provide the bottom plate.

[0048] When a bottom plate is not provided, a cross brace may be provided for interconnecting the left and right wall panels at the bottom.

[0049] While it is preferred that there is no bottom plate, it is also preferred that there is no cross brace for interconnecting the left and right wall panels at the bottom, so as to expose, for example, the roller group or Figure 8 The conveyor belt mechanism corresponding to the patterned conveyor belt 32 illustrated in the figure facilitates the maintenance of the roller set or the patterned conveyor belt 32.

[0050] The shell body as a whole is preferably a welded structure, and the connection between the shell body and, for example, the cotton storage hopper 3 and the cotton feeding part 5 is preferably a detachable connection, which is mainly achieved by bolt connection.

[0051] As for the cotton flowing channel 2, it is often configured as a chute structure, so its inner surface is often a relatively smooth surface, and the lint can slide down by its own gravity when the cotton flowing channel 2 is tilted. As for the auxiliary cotton feeding device 4 of the cotton baler based on the embodiment of the present invention, it is necessary that under the condition that, for example, the cotton storing and removing roller 12 constituting the upper conveying part and the lower conveying part arranged opposite to the upper conveying part in the vertical direction stop running, the lint cannot move forward due to the friction between the currently stopped cotton storing and removing roller 12 and the lower conveying part or mechanical hooking (such as the hooking of a spike), so that the lint can be prevented from moving forward, for example, Figure 2 The cotton feeding channel 13 is shown, and is temporarily stored in the cotton storage hopper 3. The cotton delivery trolley configured in the cotton delivery unit 5 is returned to its original position, and the cotton storage roller 12 and the lower conveying unit are activated to clamp the lint cotton to the front cotton box of the cotton delivery trolley.

[0052] During this process, the movement of the upper roller and the lower conveying part will pull the lint accumulated in, for example, the cotton storage hopper 3. This is a feeding method that is pulled and will not cause congestion. The clamping will compress the relatively fluffy lint, which is beneficial for increasing the single cotton delivery weight of the cotton delivery trolley.

[0053] Furthermore, Figures 2 to 4 、 Figure 8 and Figure 9 Two examples for constructing the cotton feeding channel 13 are shown in FIG. Figures 2 to 4 The cotton storage and spinning rollers 12 and the roller bed are used to construct the upper channel part and the lower channel part of the cotton feeding channel 13, and the left and right wall panels are used to construct the channel walls of the left and right channels; Figure 8 and Figure 9In the illustrated structure, a patterned conveyor belt mechanism is used instead of a roller bed to construct the lower channel portion of the cotton feeding channel 13 .

[0054] It should be known that, whether it is a roller bed or a conveyor belt mechanism, the principle used to achieve transportation is to achieve transportation with the help of friction. In other words, if the roller bed or the conveyor belt mechanism stops, even if there is a cotton feeding channel 13, the cotton itself has poor fluidity, and the friction of the upper conveying mechanism and the lower conveying mechanism, as well as the hooking or friction of the cotton storage and cotton removal roller 12, the cotton feeding will stagnate until the roller bed and the cotton storage and cotton removal roller 12 are started again.

[0055] It should be noted that, as mentioned above, since the cotton flowing speed of the cotton flowing channel 2 is not constant, under the condition that the cotton feeding speed of the auxiliary cotton feeding device 4 of the cotton baler is determined, it is possible that a certain degree of accumulation will be generated at the material inlet of the auxiliary cotton feeding device 4 of the cotton baler. Therefore, in some implementations, a material level detection device can also be provided at, for example, the cotton storage hopper 3, so that the auxiliary cotton feeding device 4 of the cotton baler still needs to maintain a relatively low feeding speed when, for example, the cotton delivery trolley moves forward.

[0056] For the lower conveying part, you can choose Figure 2 The roller bed shown in the example is generally composed of several rollers evenly arranged in the conveying direction, such as Figure 2 The five patterned conveying rollers 10 shown in FIG. 1 are evenly arranged in a predetermined conveying direction, and the patterns on the patterned conveying rollers 10 provide a friction interface for conveying.

[0057] exist Figure 8 In the illustrated structure, the lower conveying portion adopts a patterned conveyor belt 32. Compared with the roller bed, the patterned conveyor belt 32 has no gap between rollers and is relatively reliable.

[0058] In some other embodiments, the patterned conveyor belt 32 may also be a scraper conveyor belt, and the height of the scraper used may be relatively low, for example, less than 50 mm.

[0059] The lower conveying part is installed at the lower part of the left and right wall panels to construct the lower part of the channel, while the left and right wall panels constitute the channel walls on both sides of the channel. With the help of the lower conveying part and the left and right wall panels, a trough structure is roughly formed, which is mainly used to support lint.

[0060] Furthermore, the upper conveying section is used to cover or partially cover the upper opening of the aforementioned trough structure, and is used to construct a complete channel. This complete channel is mainly used for combing and primary compression of lint. With the help of this primary compression, the lint flow can be curbed when the upper conveying section and the lower conveying section are stopped. When the upper conveying section and the lower conveying section are started, the feeding speed of the lint is relatively constant, which is relatively beneficial for controlling the feeding amount. Under this condition, the auxiliary feeding device 4 of the cotton baler has a certain lint temporary storage function. Under the condition that its feeding channel 13 and the lint in the previous stage are sufficient, it can ensure relatively accurate control of the feeding amount.

[0061] In terms of mechanism type selection, the upper conveying part and the lower conveying part can be exactly the same or different. The upper conveying part considers more about the control of the lint flow. Therefore, the upper conveying part can have a relatively stronger friction or hooking ability on the lint than the lower conveying part.

[0062] In addition, as an auxiliary consideration, the left and right wall panels are always in a static state, so the inner surfaces of the left and right wall panels are preferably smooth surfaces.

[0063] The upper conveying part and the lower conveying part are preferably driven synchronously to ensure that the upper conveying part and the lower conveying part start and stop in sync. Figure 8 The multi-groove driving pulley 18 shown in FIG. 1 is driven by, for example, an electric motor 21. The electric motor 21 can also be replaced by a pneumatic motor or a hydraulic motor. Furthermore, the first driven pulley 15 and the second driven pulley 17 form two belt transmission mechanisms with the multi-groove driving pulley 18 via a transmission belt. Without considering the slippage of the transmission belt, the synchronization between the upper conveying portion and the lower conveying portion is easily ensured.

[0064] The two belt transmission mechanisms mentioned above can also be replaced by chain transmission mechanisms. Under this condition, for example Figure 8 The multi-groove driving pulley 18 shown in FIG. 1 replaces the double driving sprocket, and the first driven pulley 15 and the second driven pulley 17 are replaced by corresponding driven sprockets.

[0065] When the upper conveying part and the lower conveying part are respectively equipped with different power machines, the linkage of the two power machines needs to be considered, and the rest is the same as above.

[0066] The lint flowing down the cotton channel 2 is generally discharged in the form of cotton batting, although the cotton batting cannot guarantee continuity. In the cotton batting, the cotton fibers are entangled with each other and have a certain connection strength. Therefore, for the roller bed used to construct the lower conveying part, a certain gap can be left between the rollers, but it should not be too large, otherwise some cotton fibers will be easily embedded between the adjacent rollers. Therefore, the gap between the rollers on the roller bed should not be greater than 10mm. Figure 7In the illustrated structure, the gap between the rollers is 4±0.5 (unit: mm).

[0067] For Figure 2 For the patterned conveying roller 10 shown in the figure, the part used to determine the gap between the roller shafts is the top circle of the patterned conveying roller 10. For example, if the patterned conveying roller is a rectangular toothed roller, the corresponding top circle is the tooth top circle, and the corresponding gap size is the spacing between adjacent tooth top circles.

[0068] When a roller bed is used, the number of rollers used is 2 to 10. The number of rollers determines the longitudinal dimension of the cotton feeding channel 13. The roller diameter is 194±100 (unit: mm). The number of rollers is preferably 4 to 6.

[0069] In addition, Figure 2 and Figure 4 In the illustrated structure, a smooth roller 8 is independently provided at the end of the roller bed, mainly used to prevent the lint quilt from rolling down.

[0070] The roller diameter of the smooth roller 8 is roughly equivalent to the roller diameter of the patterned conveying roller 10. In a preferred embodiment, the roller diameter of the smooth roller 8 is slightly smaller than the roller diameter of the patterned conveying roller 10, generally 8 to 15 mm smaller, which is beneficial to the smooth guidance of the lint at the end of the cotton feeding channel 12.

[0071] Regarding the guiding of lint at the end of the feeding channel 12, Figure 8 In the illustrated structure, a guide plate 6 is provided on the housing at the end of the patterned conveyor belt 32. Similarly, for the roller bed, a guide plate 6 can also be provided at the end of the roller bed in the conveying direction to facilitate the smooth guidance of the lint at the end of the conveying direction.

[0072] Furthermore, when the guide plate 6 is provided, the gap between the feed end of the guide plate 6 and the last roller is not greater than 4 mm. The gap can be as small as possible without causing motion interference.

[0073] As for the roller shaft on the roller bed, it is preferred to use a rubber-covered grooved roller.

[0074] As mentioned above, the upper conveying part has a slightly different function from the lower conveying part. Figure 4 and Figure 9 The display is relatively clear, mainly in the conveying direction, that is, the longitudinal direction, the span of the upper conveying part is relatively small, such as Figure 4 The cotton storing and rejecting roller 12 shown in the figure is one in number. Even when a plurality of cotton storing and rejecting rollers 12 are provided, the number thereof is generally no more than three.

[0075] At this time, for example, the cotton storing and removing roller 12 forms a throat of the cotton feeding channel 13, where the lint is compressed, which is beneficial for starting and stopping the conveying of the lint.

[0076] exist Figure 4 and Figure 9 In the illustrated structure, the cotton storing and removing rollers 12 are offset backward relative to the lower conveying part. Under the condition that the number of cotton storing and removing rollers 12 is relatively small, on the one hand, the start and stop of cotton feeding can be effectively controlled. At the same time, when feeding cotton, the lint cotton can be fed into the front cotton box of the cotton delivery cart more quickly, and it is not easy to cause choking of the cart.

[0077] The roller diameter of the cotton storage and cotton removal roller 12 is compared with the roller diameter of the cotton storage and cotton removal roller 12. Figure 4 The roller diameter of the patterned conveying roller 10 on the roller bed is large, and the roller diameter of the cotton storing and rejecting roller 12 is 380±200 (unit: mm).

[0078] The cotton storage and cotton removal roller 12 adopts a toothed roller or a spiked roller. If a toothed roller is adopted, the number of teeth is at least two, but generally not less than six. The number of teeth is usually no more than twenty-four, but generally needs to be controlled within twenty.

[0079] Regarding the teeth used, triangular teeth are preferred, and the vertex angle of the triangular teeth is generally less than or equal to 30 degrees. The tooth height of the teeth used in the cotton storage and cotton removal roller 12 is 6 to 126 mm, which has a wide range of applications. The tooth height is negatively correlated with the number of teeth, and a cotton storage and cotton removal roller 12 with a relatively large tooth height is preferred. The tooth height is generally greater than 18 mm, but preferably less than or equal to 72 mm. In more options, the tooth height is less than or equal to 36 mm.

[0080] About the cotton storage and cotton rejection roller 12, a pricking roller can also be selected.

[0081] The spacing L between the upper and lower conveyors is 74mm to 474mm. It should be noted that, for example, the thickness of the batting conveyed by the lint chute 2 is generally around 70mm. This thickness varies depending on the machine model. When the upper and lower conveyors stop operating, the flow of lint is inhibited, causing it to gradually accumulate. Choosing the appropriate spacing L between the upper and lower conveyors helps control lint compression and feeding efficiency.

[0082] Regarding the distance L between the upper conveying part and the lower conveying part, 148mm~256mm is the better choice.

[0083] exist Figure 1 In the illustrated configuration, the auxiliary cotton feeding device of the cotton baler is positioned obliquely within the cotton feeding system. In a relatively preferred embodiment, its inclination angle (based on the feeding direction of the cotton feeding channel 13) is slightly greater than the inclination angle of the cotton flow channel 12. However, in some embodiments, the inclination angle may be the same as or slightly less than that of the cotton flow channel 12. Accordingly, the conveying direction determined by the lower conveying portion is at an angle of 15° to 60° downward with respect to the horizontal plane.

[0084] In a more preferred embodiment, the angle between the conveying direction determined by the lower conveying part and the horizontal plane is 45°~50°.
