Description

Technical Field

[0001] The utility model relates to a cotton bale sampling actuating assembly for sampling, and also relates to a sampling device equipped with the cotton bale sampling assembly. Background Art

[0002] In view of the fact that the cotton processing production line processes raw cotton into lint in a relatively closed environment, and finally the lint is produced in the form of cotton bales, the process equipment rooms in front of the baling machine on the cotton processing production line basically transfer materials through pipelines. Therefore, the inspection of product quality often needs to be carried out after the lint is baled. Although there are currently on-line cotton quality detection devices, compared with flowing materials, static detection of lint, for example, is more accurate. On-line detection is more for adjusting the process parameters of cotton processing equipment, and usually cannot be used as data for evaluating the quality of the final product (lint).

[0003] As mentioned above, the standard weight of a cotton bale is 227±10 kg, and the standard cotton bale sizes mainly have two types: 1400mm×530mm×700~900mm (international standard), 1590mm×530mm×650~800mm (new cotton packaging size). It can be seen that the cotton bale is heavy and relatively small in volume. In other words, the cotton bale is actually formed by compacting the fluffy lint and then bundling it with, for example, steel wires. For traditional cotton bale sampling, mostly manually use a knife to cut a small opening on the side of the cotton bale, and then manually or use pliers to extract a predetermined amount of lint sample from the small opening. Since the compaction degree of the lint is very high, it is very difficult to manually remove the lint from the cotton bale. Even with the help of pliers, because the jaws of ordinary pliers suitable for manual operation are too small, it is necessary to clamp multiple times to meet the lint amount required for sampling, which is not only inefficient but also prone to injury accidents.

[0004] In order to reduce the human input, in some implementations, a machine clamp is used to take samples of lint in a bale. It includes a pair of strip plates that can be clamped against each other in the direction guided by a guide rail. One end of the strip plate is a slider guided by the guide rail, and the other end is an arc top, and the arc top is blade-shaped, which is conducive to inserting the strip plate into the bale. A first air cylinder is provided to drive the two strip plates to clamp against each other. A second air cylinder is also provided, which is used to drive the seat frame on which the guide rail is installed, so that the seat frame moves in the direction of approaching or departing from the bale. When in use, the second air cylinder pushes the seat part to insert the two clamping plates into the bale. Then the first air cylinder acts to clamp a certain amount of lint. The second air cylinder resets to take out the lint clamped between the two strip plates. The first air cylinder resets, and the lint clamped between the two strip plates is released and falls to a predetermined position. As described above, the strip plate has a blade-shaped head, which is conducive to inserting the strip plate into the bale. However, when the two strip plates clamp the lint, they completely rely on friction to clamp the lint. As described above, the compaction degree of lint in the bale is very high, and clamping by relying on friction is very likely to lead to sampling failure.

[0005] In some implementations, a multi-claw structure is adopted. Specifically, four claw bodies are hinged on the outer edge of a fixed seat. The fixed seat has a central hole. A push rod guided in the central hole is provided. One end of the push rod is hinged with driving arms corresponding to the claw bodies one by one, and the other end of the driving arm is hinged with the claw body, thus forming a four-claw expansion and contraction structure. In the initial state, the four claw bodies are in an outward-expanded state, and then they are inserted into the bale. The push rod retracts, causing the four claws to retract inward to clamp a certain amount of lint. At this time, the lint is not easy to fall off, that is, the problem of sampling failure is likely to occur. However, the installation method of the multi-claw body based on the hinge shaft can refer to the umbrella bone structure. The hinge shaft is too short, and the anti-torsion and shear ability is weak. And in the initial state, the claw bodies are outward-expanded. The claw bodies are inserted into the bale obliquely, but the moving direction of the fixed seat is straight, and the claw bodies will be subjected to a large outward-expansion force, which is likely to cause damage to the claw bodies.

[0018] Optionally, the second linear drive mechanism is a cylinder.

[0019] The moving clamping jaw is guided by a clamping guide rail and is fixedly installed on a moving jaw slider adapted to the clamping guide rail.

[0020] Correspondingly, the push rod of the cylinder is arranged parallel to the clamping guide rail and is fixedly connected to the moving jaw slider.

[0021] Optionally, the clamping jaws are bending plates, and the two corresponding clamping jaws are butted against each other at the ends of the clamping jaws, and the included angle formed at the butting place is greater than or equal to 75° and less than or equal to 160°.

[0022] Optionally, a reinforcing plate is provided on the back side of the clamping jaws in the butting direction.

[0023] Optionally, the length of the clamping line or surface formed by butting is 50 mm to 150 mm.

[0024] Optionally, the first linear drive mechanism is a telescopic cylinder, and this telescopic cylinder is fixed on the base.

[0026] The end of the telescopic slide block is provided with a plate body which is perpendicular to the telescopic direction of the telescopic cylinder and is used for installing the material clamping driving mechanism.

[0027] According to a second aspect of the embodiment of the utility model, a sampling device is provided, comprising:

[0028] A sampling platform for holding cotton bales;

[0029] A cotton bale sampling actuating assembly, located on one side of the sampling platform, is the cotton bale sampling actuating assembly described in the first aspect of the embodiment of the utility model; and

[0030] The sample receiving device is located at the reset side of the first linear drive mechanism to receive the cotton sample released by the cotton bale sampling actuating assembly.

[0031] Optionally, a straightening frame is further included at the rear of the sampling platform to straighten the cotton bale conveyed to the sampling platform.

[0032] Optionally, the uprighting frame is located on one side of the rear portion of the sampling platform;

[0033] Correspondingly, an anti-deviation frame is provided on the side of the sampling platform opposite to the side where the straightening frame is located, and the cotton bale sampling actuating assembly is located at the front side of the straightening frame and opposite to the anti-deviation frame.

[0038] According to the embodiment of the utility model, the cotton bale sampling actuation assembly adopts two sets of driving mechanisms, one of which is a first linear driving mechanism, which is used to send the sampling head to the cotton bale, that is, to achieve the actuation of approaching or moving away from the cotton bale. The main component of the sampling head is the clamping jaw, which can be a pair of dynamic clamping jaws, or a structure in which a dynamic clamping jaw and a static clamping jaw are matched. The sampling head is installed on the first linear output member of the first linear driving mechanism, and the actuation of the sampling head itself is realized by the clamping driving mechanism, that is, to achieve the engagement or opening between a pair of dynamic clamping heads, or to achieve the engagement or distance between a single dynamic clamping head and a static clamping head. Furthermore, regarding the position of the sampling head, on the one hand, the static clamp can be used as a position-holding abutment component, and on the other hand, for the sampling head with two dynamic clamps, a position-holding abutment component can be provided separately. Based on the driving force of the first linear drive mechanism, the position-holding abutment component is pressed against the cotton bale, and the sampling head moves to take samples, which is equivalent to taking samples from the cotton bale instead of probing into the cotton bale. The squeezing force between the lint cotton that needs to be overcome for surface taking is relatively small, which is equivalent to relying on squeezing deformation and then clamping a predetermined amount of lint cotton, and the success rate is relatively high. At the same time, the surface taking itself requires the sampling head to bear less force, and even if it has the same structure and construction as the prior art, such as the jaws, it will have better reliability of use because the force environment is relatively good.

[0051] The cotton bale sampling actuating assembly is a component of the cotton processing production line. As mentioned above, the cotton processing production line is usually closed during the ginned cotton baling process, making it difficult to sample. Here, it is used to represent the continuity of each process step of the cotton processing production line. Simply from the perspective of material transportation, the transportation direction is generally called the front-back direction. Correspondingly, material transportation often also has a definite left-right direction, and the direction perpendicular to the reference plane determined by the front-back, left-right directions is usually called the up-down direction.

[0052] In addition, the front-back direction is also called the head-tail direction, the long direction or the longitudinal direction, while the left-right direction is also called the side direction, the transverse direction or the width direction.

[0053] In view of the fact that there are two themes in the embodiments of the present invention, and the cotton bale sampling actuating assembly 2 is a component of the sampling device. The cotton bale sampling actuating assembly 2 can have its own reference system. In particular, the cotton bale sampling assembly 2 has two driving mechanisms, and each driving mechanism can also have its own reference system. It should be known that under the condition of being able to be correctly understood, no special description of the relevant reference system is made in the embodiments of the present invention.

[0054] In addition, in the embodiments of the present invention, the term names used, such as the clamping cylinder 21, do not mean that it has a clamping function by itself, but are used for name distinction from other technical features and do not have a substantial limiting effect on itself.

[0055] Figure 1 The exemplified sampling device is a process equipment of the cotton processing production line. As can be seen from the figure, there are several plate bodies for connection at the lower right part of the main frame 7. In other words, it can be connected to other process equipment or other brackets. The main frame 7 can also be independently set. This is basic common sense of the production line and will not be elaborated here. The connection structure shown in the figure that is not connected to other components does not mean an incomplete description of the sampling device.

[0056] Figure 1 The cotton bale sampling actuating assembly 2 in... is the actuating part of sampling and is used for being located at Figure 1Sampling is performed on the bale on the sampling platform 5 illustrated in the figure, and the bale sampling actuation assembly 2 is generally visible in Figure 4 the illustrated structure, which has a vertical arm 26 in the figure. Comparing Figure 1 , the vertical arm 26 is mainly used to install the bale sampling actuation assembly 2 on one side of the sampling platform 5, such as the left side in the figure. If viewed from the bale conveying direction, it is located on the right side of the sampling platform 5. However, based on Figure 1 the illustrated structure, it can also be known that whether the bale sampling actuation assembly 2 is located on the left side or the right side of the sampling platform 5 does not affect the realization of sampling itself. As for the specific selection, those skilled in the art can make a choice according to the specific characteristics of the product they design, rather than necessarily being located on a specific side of the sampling platform 5.

[0057] Figure 4 The base including the vertical arm 26 in the figure is a form of the base. Considering the working stroke of, for example, the telescopic cylinder 29, the sampling head is located on one side of the sampling platform 5. For example, there is a certain span between the installation position of the telescopic cylinder 29 and the sampling platform 5. At this time, the frame on which the sampling platform 5 is installed and the frame on which, for example, the telescopic cylinder 29 is installed can be interconnected or independent of each other. Simply in the embodiments of the present invention, the base is only used to represent the part that can be used as the installation base for other components on the bale sampling actuation assembly 2, rather than indicating that it has a specific form. It should be understood that the base is a relatively static part in the embodiments of the present invention.

[0058] In Figure 4 the illustrated structure, the base includes a vertical arm 26 and a vertical plate. The vertical arm 26 and the vertical plate are fixedly connected, such as non-detachable connections like welding or detachable connections using screws, etc.

[0059] The vertical plate of the base can be used as the installation base for, for example, the telescopic cylinder 29, and the vertical arm 26 itself can also directly be used as the installation base for the telescopic cylinder 29.

[0060] The vertical plate of the base is also perpendicular to the bale conveying direction. However, it should also be understood that the bale conveying direction does not mean that the long side of the bale exactly coincides with its conveying direction in the current state of the bale. Although it should be consistent in the ideal state, some other embodiments below will involve the problem of how to straighten the bale.

[0061] For reference: For example, a bale with specifications of 1400mm×530mm×700~900mm represents the length×width×height of the bale. In some implementations, the relatively shorter edge is used to represent the height. At this time, the bale specifications are expressed as length×height×width to ensure more stability when the bale is placed. The long side among them is used to determine the normal conveying direction of the bale.

[0062] During the transportation of the bale of cotton, the side surface is more the surface of the bale of cotton corresponding to 1400mm×530mm. It should be known that when packing the bale of cotton, it is generally bundled with steel wires or steel bands to form a lint compressed structure roughly in the shape of a cuboid. However, due to the relatively few bundling positions, the unbundled positions will still bulge relative to the bundled positions. Therefore, the so-called cuboid structure is not an ideal cuboid structure, but it does not affect the correct understanding of its length, width, and height by those skilled in the art.

[0063] In addition, before the bale of cotton is sleeved after bundling, the lint on the bale of cotton is exposed, and lint sampling can be carried out at the unbundled positions on the bale of cotton. Although in some implementations, the bale of cotton has been sleeved with a cotton bag, a detection opening can also be left or cut out for lint sampling.

[0064] Furthermore, a first linear drive mechanism is provided to drive the sampling head to move linearly in the direction of approaching and departing from the bale of cotton. For the convenience of description, the sampling position can be called the target position, and the position of restoring from the target position to the position far from the bale of cotton is the reset, and the corresponding position of the reset is the initial position, which can also be called the reset position.

[0065] In view of the fact that the side surface of the bale of cotton is roughly a vertical surface, therefore, the driving direction of the first linear drive mechanism is roughly horizontal and is roughly perpendicular to the side surface.

[0066] The sampling head, as the object to be driven, must be installed on the first linear drive mechanism and must be located on the output member of the first linear drive mechanism, that is, the first linear motion output member, such as the slide plate dragged by the lead screw nut of the lead screw mechanism. At this time, the axis of the lead screw is perpendicular to the side surface of the bale of cotton, so as to push the slide plate in the axial direction of the lead screw. At this time, the sampling head carried by the slide plate will move reciprocally in this direction.

[0067] Correspondingly, the first linear drive mechanism uses the base as the frame, such as Figure 4 In the exemplified structure, the first linear drive mechanism in the figure is a component, which is the telescopic cylinder 29 shown in the figure. The main technical conditions considered for using the cylinder are that the cylinder has a fast response speed and its working medium is air, which will not pollute the lint in the bale of cotton.

[0068] Relatively speaking, the hydraulic cylinder is also a commonly used linear motion component in industry. Its power density is large. Under the condition of the same volume, its power is not only greater than that of the cylinder but also higher than that of electric components, such as linear motors.

[0069] In addition, the linear motor uses electricity to generate power and there is no medium that can cause pollution. Therefore, the linear motor can also be selected under the condition of considering fire prevention.

[0070] For a rotary electric machine, a mechanism capable of converting rotary motion into linear motion is required to be applied to the linear motion required by the embodiments of the present invention. For example, in the foregoing nut-screw mechanism, the screw thereof can be driven by a rotary electric machine.

[0071] Other available linear motion mechanisms such as a crank-slider mechanism can also be used. For another example, in a rack and pinion mechanism, a rotary electric machine can be used to drive the pinion, and the rack meshing with the pinion is pushed to perform linear motion.

[0072] The material clamping drive mechanism is equivalent to the end drive mechanism and is mainly used to implement the sampling action. As the end drive mechanism, it must also be the object to be driven. Therefore, the material clamping drive mechanism uses the first linear motion output member as the frame.

[0073] As described above, for the convenience of description, the tool head with jaws for directly clamping cotton samples is called a sampling head. For the sampling head, its sampling action is mainly implemented by the material clamping drive mechanism. Therefore, the movable part in the sampling head can form the output member of the material clamping drive mechanism. However, in the embodiments of the present invention, all the components of the sampling head do not necessarily form the output member of the material clamping drive mechanism. Literally speaking, the material clamping drive mechanism is mainly used to implement the material clamping action, rather than being entirely included in the material clamping drive mechanism.

[0074] The sampling head has a pair of jaws, and the corresponding two jaws are adapted with two configurations based on the motion relationship. One configuration is that both jaws are movable jaws, that is, both are driven by the material clamping drive mechanism. The other configuration is that one of the two jaws is a movable jaw and the other is a static jaw, as Figure 4 shown by the movable jaw 24 and the static jaw 25 in

[0075] For the clamping action, it can be implemented based on linear motion or other motion forms. For example, in the structure illustrated in Figure 4 the clamping is implemented based on linear motion. The movable jaw 24 therein is driven by the clamping cylinder 21 shown in the figure and is driven in the direction of approaching or departing from the static jaw 25, so as to implement clamping or unclamping.

[0076] Since the material clamping drive mechanism uses the first linear motion output member as the frame, the relatively static static jaw needs to be fixed on the first linear motion output member.

[0077] When both jaws are movable jaws, the two movable jaws implement clamping or unclamping based on a synchronization mechanism, that is, the same material clamping drive mechanism is used to drive the two movable parts. These two movable parts are based on the synchronization mechanism, thereby improving the success rate of sampling.

[0078] Based on the principle of the present utility model, in the present utility model, it is not pursued to insert the clamping claws into the bale of cotton. Therefore, the force required for the sampling action during sampling is relatively small. It should be known that for cotton samples, a relatively large amount is not required, and only the amount adapted to meet the inspection requirements is sufficient. Therefore, inserting a sampling head, for example, into the bale of cotton for sampling does not conform to the basic concept of the present utility model. However, partially squeezing the moving clamping claw into the shallow layer of the bale of cotton based on the clamping material driving mechanism does not violate the basic concept of the present utility model either.

[0079] Furthermore, when both corresponding clamping claws are moving clamping claws, a positioning abutting component installed on the first linear motion output member is additionally provided to limit the engagement depth between the moving clamping claw and the bale of cotton.

[0080] Then correspondingly, if one of the clamping claws is a stationary clamping claw, then the stationary clamping claw itself can serve as the positioning abutting component, that is, the stationary clamping claw first comes into contact with the bale of cotton, thereby limiting the depth of the moving clamping claw cooperating with the stationary clamping claw from intervening into the shallow surface layer of the bale of cotton.

[0081] Correspondingly, the positioning abutting component is preferably fixedly arranged on the first linear motion output member, and it can be a block or a rod. It should be known that the lint compactness in the bale of cotton is very high, and even for a rod, it is not easy to insert. Therefore, the rod can also serve as the positioning abutting component. If accurate limitation is required, a component for increasing the contact area, such as a round plate or other structures, can be additionally provided at the end of the rod.

[0082] When the sampling head is equipped with a pair of moving clamping claws, the two moving clamping claws preferably achieve the sampling action by swinging, and their synchronization is relatively easier to achieve. In some other embodiments, a linear drive mechanism can also be used to achieve clamping or unclamping, such as a screw rod with two sections of threads with opposite helix directions, and the same drive mechanism can be used to achieve the clamping or unclamping actions of the two moving clamping claws.

[0083] The swinging method is relatively easy to implement. Specifically, in some embodiments, the two moving clamping claws are hinged to the first linear motion output member through hinge shafts with parallel axes, and the roots of the two moving clamping claws have gear-shaped parts or the hinge shafts form gear shafts, and gears are installed on the gear shafts; furthermore, the corresponding two gears or the roots of the two gear-shaped parts are meshed to achieve the synchronization between the two moving clamping claws.

[0084] Correspondingly, one of the two gears can be directly driven by, for example, a motor that can output rotational motion.

[0085] In addition, there are relatively many ways to achieve swing rotation. For example, a swing cylinder can directly output swing. For other types of swing output mechanisms or components, they will not be listed one by one here, and they all belong to the general knowledge in the mechanical field. In the embodiments of the present invention, emphasis is placed on the selection of the motion form rather than the improvement of the mechanism for realizing this motion form.

[0086] Furthermore, when one of the two clamping jaws is a stationary clamping jaw and the other is a moving clamping jaw, the stationary clamping jaw itself can be used for the in-place abutment of the first linear motion output member; at the same time, the motion form of the moving clamping jaw cooperating with the stationary clamping jaw at this time can be linear motion or swing rotation. Correspondingly, the clamping material driving mechanism is a second linear driving mechanism or a swing rotation mechanism.

[0087] Correspondingly, when the clamping material driving mechanism is a second linear driving mechanism, a relative linear motion is performed between the moving clamping jaw and the stationary clamping jaw.

[0088] When the clamping material driving mechanism is a swing rotation mechanism, the moving clamping jaw constitutes a swing rotation output member.

[0089] Regarding the selection of the second linear driving mechanism, reference can be made to the first linear driving mechanism described above, and details will not be repeated here. Similarly, for the swing rotation mechanism, reference can also be made to the description of the swing rotation of the two moving clamping jaws, and details will not be repeated here.

[0090] As a specific example, Figure 4 In, the moving jaw 24 and the stationary jaw 25 are substantially the same in shape and are arranged in a left-right opposed manner. The moving jaw 24 is driven by the clamping cylinder 21 shown in the figure. The clamping cylinder 21 is installed on the telescopic slide plate 28. The telescopic slide plate 28 is substantially a T-shaped plate. The part of it used to cooperate with the telescopic guide rail to determine the telescopic guide rail pair 27 is the first vertical plate parallel to the axis of the telescopic cylinder 29. Another second vertical plate is fixedly installed at the end of the first vertical plate and is perpendicular to the axis of the telescopic cylinder 29. The clamping cylinder 21 is installed on one side of the second vertical plate, and the stationary clamping jaw 25 is installed on the other side of the second vertical plate. A clamping guide rail 23 is also constructed on the other side of the second vertical plate for guiding the moving jaw slide plate 22. The moving jaw 24 is installed on the moving jaw slider 22.

[0091] In Figure 5 the exemplified structure is a structure of a moving jaw 24, and the stationary jaw 25 can adopt the same structure. Figure 5 The moving jaw 24 in is a bent plate to facilitate the formation of a better clamp structure. The stationary jaw 25 cooperating with it adopts the same structure. Thus, when the two are closed, the ends of the two clamping jaws are joined to form the cavity penetrating up and down shown in the figure.

[0092] Furthermore, the two corresponding clamping jaws are matched at the ends of the clamping jaws, and the angle formed at the matching position is greater than or equal to 75° and less than or equal to 160°. The angle should not be too large, otherwise it will produce a large sampling resistance; nor should it be too small, otherwise it will make it more difficult to clamp the material.

[0093] In addition, Figure 5 As shown, the clamping jaw has a reinforcing plate 244 on the back side in the mating direction.

[0094] In addition, as a further consideration for the sampling success rate and its own reliability, the length of the clamping line or surface formed by the clamping jaws is 50mm~150mm. Figure 4 and Figure 5 As shown, under normal use, the clamping line or surface formed by the matching is a vertical line or surface, and its length is obviously based on the corresponding line segment length when it is in the form of a line, and the length in the up and down direction when it is in the form of a surface.

[0095] When the two clamps are aligned and then separated, i.e., loosened, the cotton sample will naturally fall off and easily detach from between the two clamps.

[0096] As for the sampling device, as mentioned above, it includes the sampling platform 5 and the aforementioned cotton bale sampling actuating assembly 2, as well as a sample receiving device, so as to facilitate workers to take away the cotton sample.

[0097] The sampling platform 5 is located on the main path of the cotton production line and is used to hold the cotton bales conveyed from the cotton bale line. How to accurately stop the cotton bales on the sampling platform 5 belongs to the overall control of the cotton processing production line, which does not belong to the composition of the utility model and will not be described here.

[0098] The cotton bale sampling actuating assembly 2 is located on one side of the sampling platform 5, so that sampling and releasing the obtained cotton sample can be completed by approaching or moving away from the side. Therefore, the sample receiving device and the cotton bale sampling actuating assembly 2 are located on the same side of the sampling platform 5, and are also located on the reset side of the first linear drive mechanism to receive the cotton sample released by the cotton bale sampling actuating assembly 2.

[0099] As mentioned above, in an ideal state, the long side of the cotton bale should be consistent with the conveying direction of the cotton bale. Therefore, in a preferred embodiment, the posture of the cotton bale on the sampling platform 5 should be as close to or as close to the ideal state as possible. In some embodiments, a straightening frame 3 is also included at the rear of the sampling platform 2. The rear here is the cotton bale input side of the sampling platform 2. In other words, the cotton bale is straightened by the straightening frame 3 during the process of entering the sampling platform 2, so that its posture is closer to the ideal state.

[0100] Since straightening is a relatively common process equipment in the mechanical field, in the embodiments of the present invention, the use of the concept of straightening is first emphasized. Furthermore, those skilled in the art select a known straightening device in the mechanical field based on the concept of straightening.

[0101] In particular, although the bale is not a regular cuboid shape, it has the basic outline of a cuboid shape and belongs to the products in the mechanical field that are easy to be straightened. Therefore, there are relatively many straightening devices available in the mechanical field.

[0102] In Figure 3 In the illustrated structure, the straightening frame 3 adopts a rod structure, and the set height of the rod structure is approximately equivalent to the position of the waist line of the bale, and can be slightly higher.

[0103] The straightening frame 3 of the rod structure has at least an inlet structure corresponding to the inlet end of the bale, such as Figure 3 the inlet head 311 shown in, so as to facilitate straightening the deviated bale through the inlet head 311.

[0104] In Figure 1 In the illustrated structure, the straightening frame 3 is located at one side of the rear part of the sampling platform 5; correspondingly, an anti-deviation frame 6 is provided on the side of the sampling platform 5 opposite to the side where the straightening frame 3 is located, and the bale sampling actuator assembly 2 is located in front of the straightening frame 3 and opposite to the anti-deviation frame 6, effectively avoiding assembly interference and movement interference while ensuring reliable straightening.

[0105] Since the structures of the straightening frame 3 and the anti-deviation frame 6 are relatively simple, their own structures and assembly structures can be clearly understood only through the structures illustrated in the drawings, and will not be elaborated here.

[0106] In addition, although the bale is a standard bale, there are still some errors in its size, and whether the bale is damp or not will affect straightening. Therefore, at least the components of the straightening frame 3 for providing straightening have a structure with adjustable distance from the other side of the sampling platform 5 in the left-right direction of the sampling platform 5.

[0107] Correspondingly, the anti-deviation frame 6 also has a corresponding adjustable function, such as Figure 6 the long hole 62 opened on the mounting plate 61 of the anti-deviation frame 6 shown in, and the extending direction of the long hole 62 is the left-right direction of the sampling platform 5.

[0108] And Figure 2 and Figure 3 show an adjustment structure of the straightening frame 3, mainly relying on the adjustment hole 321 for adjustment, which is described clearly in the figure and will not be elaborated here.

[0109] Another in Figure 1An example structure also provides a sampling device, such as the funnel 4 shown in the figure, which is used to directly receive the cotton sample and export it downward. At this time, the funnel 4 is located below the sampling head in the reset state.

[0110] Another feeding device is provided to receive the cotton sample from the lower end of the funnel 4, such as Figure 1 the cotton sample lifting and conveying device 1 similar to a ladder in the figure, which lifts the cotton sample to a height convenient for the operator to pick up, thus facilitating the operator's sampling.
