Example 1

The embodiment provides an even equipment is clapped to AI cotton fine hair intelligence, and it is used for patting the cotton fine hair goods that have the cotton fine hair to inside filler evenly distributed of making the cotton fine hair goods. As shown in fig. 1 and fig. 2, the product of the intelligent cotton velvet beating and evening device provided by the embodiment is a small horizontal machine. The automatic feeding and flattening machine comprises a machine frame 1, wherein a conveying mechanism 2, a flattening mechanism 3, a detecting mechanism 4, a beating mechanism 5 and a controller 6 are respectively arranged on the machine frame 1. The surface of the frame 1 is also covered with a plurality of sealed cover plates, the cover plates can protect internal mechanisms, and each processing mechanism is prevented from being damaged due to exposure to the external environment.

The conveying mechanism 2 is used for conveying the cotton velvet products to be treated to a treatment mechanism of which the rear section executes different procedures in sequence. In this embodiment, the conveying mechanism 2 may be any one of a belt conveyor, a plate conveyor, a mesh belt conveyor, and a trolley conveyor. Because the embodiment provides a small-size product, the conveying mechanism 2 that consequently adopts is a guipure conveyer, as shown in fig. 3, this guipure conveyer's that this embodiment provided conveyer belt is laid along vertical direction, and four sides are tensed through multiunit sprocket respectively to drive the sprocket rotation and then realize the conveyer belt conveying through two sets of motors. The present embodiment provides a conveyor belt having a horizontal conveyor deck, wherein the lint products to be treated are fed from one side of the conveyor deck and tapped from the other side. Meanwhile, in the vertically arranged conveying belt, the space above and below the conveying table top can be used for mounting various related devices, so that the limited internal space of the equipment is fully utilized.

Of course, in other implementable technical solutions, other types of conveyors may be adopted, and when the type and layout of the conveyors are changed, the layout of the mechanisms such as the flattening mechanism 3, the detecting mechanism 4, and the beating mechanism 5 may also be adaptively adjusted.

This implementation provides's even equipment of cotton velvet intelligence bat main advantage can carry out selectively accurate the patting to the different regions of cotton velvet goods according to the distribution state of the inside filler of cotton velvet goods, and then makes inside cotton velvet can quick evenly distributed, avoids carrying out invalid the patting. The premise for realizing fine beating is to detect the distribution state of the fillers in the lint product.

In order to realize carrying out accurate detection to the distribution state of the inside filler of cotton velvet products, this embodiment adopts flattening mechanism 3 to carry out the preliminary treatment to the cotton velvet products of input earlier to extrude the air in the cotton velvet products and make cotton velvet products surfacing. The distribution condition of the fillers of the cotton velvet product can be accurately detected by flattening and extruding air, so that the problem that the appearance difference between a high-density area and a low-density area of the fillers is small and the fillers cannot be accurately distinguished under the fluffy state of the fillers is solved.

It is to be emphasized that; the flattening mechanism 3 is not a necessary mechanism of the intelligent cotton velvet beating and leveling device provided by the embodiment. For example, when the filling amount is detected for some thin or better light-transmitting cotton velvet products, the product can not be flattened. The corresponding leveling device can be provided with no flattening mechanism 3.

Various technical schemes can be adopted for realizing the flattening of the cotton velvet product; in the embodiment, the flattening mechanism 3 adopts a negative pressure exhaust device to flatten the cotton velvet product. Specifically, as shown in fig. 4 and 5, a negative pressure exhaust device is disposed right below the front side of the conveying table in the present embodiment, an airflow inlet of the negative pressure exhaust device is located right opposite to the upper conveying belt, and the airflow inlet is enclosed by a plurality of partition plates to form a fan cover 31. Because the conveyer belt that this embodiment adopted is netted, and the gas permeability is better, after the cotton velvet goods that await processing covered the fan housing 31 top of airflow entrance among the negative pressure exhaust apparatus, negative pressure exhaust apparatus can carry out the vacuum suction to conveyer belt top, and then forms a negative pressure zone in local, extracts the air in the cotton velvet goods for the cotton velvet goods are by automatic "flattening of atmospheric pressure.

Further, in other embodiments, the flattening mechanism 3 may also employ a flat press, a double-roll press, or the like. The flat extruder extrudes the cotton velvet products through a pair of flat lifting mechanisms arranged above and below the conveyer belt, so that the cotton velvet products are flattened. The double-roll extruder extrudes the cotton velvet product through a pair of winding rolls arranged above the conveying belt, and then the cotton velvet product is flattened. The double-roll extruder comprises two winding rolls which are arranged in parallel up and down, a gap is arranged between the two winding rolls and the two winding rolls rotate reversely, and then input cotton velvet products are fully extruded into a flat shape. The above three flattening mechanisms 3 can be optimized according to different designs. Or a plurality of flattening mechanisms 3 can be adopted in the same equipment at the same time, such as related devices of vacuum suction and winding roller extrusion are installed at the same time. In addition, in other embodiments, other equipment may be used to flatten the lint product along its side of deployment.

After the flattening treatment, the intelligent cotton velvet arranging equipment can detect the cotton velvet filling amount of different areas in the flattened cotton velvet product through the detection mechanism 4. The detection mechanism 4 includes a light source system, an image acquisition device, and an image analysis system. The light source system emits a linear or matrix beam of light for detection toward the surface of the lint product. The image acquisition device acquires the surface image of the cotton velvet product under the irradiation condition of the light source system. The image analysis system is used for partitioning the cotton velvet product, identifying the deformation state of light rays or the size of light spots on the surface of the cotton velvet product in each partition, and finally generating the corresponding sparse grade of each partition according to the state of the light rays or the light spots so as to obtain a cotton velvet distribution state diagram. Wherein, the sparse level is a customized physical quantity for representing the cotton wool filling amount of the current subarea.

The detecting mechanism 4 is a core mechanism in this embodiment, and the main function of the mechanism is to detect the filling amount of the lint inside the lint product inputted on the conveying mechanism 2. The embodiment respectively provides two schemes capable of realizing the detection of the filling amount of the cotton velvet.

In the first embodiment, as shown in fig. 6, the light source system and the image capturing device are respectively located at the upper and lower sides of the lint product to be detected loaded on the conveying mechanism 2. Wherein, the light source system adopts a dot matrix laser light source 41 and is positioned at the position below the corresponding input cotton velvet product; the image acquisition device adopts a camera 42, and the camera 42 is arranged right above the dot matrix laser light source 41. The light emitted by the dot matrix laser source 41 in the scheme is perpendicular to the cotton velvet products on the conveying belt. When the cotton velvet product passes through the detection area of the detection mechanism 4, the light source system starts to work, and at this time, the dot-matrix laser light source 41 irradiates on the cotton velvet product, so that a plurality of light spots are uniformly distributed on the surface of the cotton velvet product. At this time, the camera 42 starts to take a picture and acquires an image of the upper surface of the lower lint product, in which projected light spots are uniformly distributed on the surface of the lint product. In this embodiment, the light source system adopts a laser light source, and in other embodiments, the light source may also adopt a directional strong light source with collimation.

The images captured by the camera 42 are transmitted to an image analysis system for analysis. When the image analysis system processes, the standardized subarea is firstly carried out on the cotton linter product according to the distribution positions of the light spots, so that each light spot is positioned in the center of the subarea. Then, performing sparse grade scoring on each partition according to a preset 'spot diameter-sparse grade' list; and finally, combining the adjacent partitions with the same sparse level to obtain the required cotton velvet distribution state diagram.

Specifically, the work flow of the image analysis system is substantially as shown in fig. 7, and the light spot distribution of a flattened pillow-like lint product after being irradiated by the dot-matrix laser source 41 is substantially as shown in fig. 7. The image analysis system first performs a standardized partition of the lint product, and in this embodiment, the standardized partition is substantially as shown in fig. 7 (a). It can be seen that the pillow is divided into 4 × 6 for 24 partitions, and in this case, the above partitions can be encoded, for example, the regions are encoded as A1B1, A1B2, A1B3, A1B4 \8230 \ 8230; A6B1, A6B2, A6B3, A6B4, respectively, according to the horizontal and vertical coordinates. The purpose of encoding in the step is to position different areas of the cotton velvet product in order to facilitate later beating action, so as to realize accurate beating.

Next, the image analysis system again detects the size of the light spot within the partition. According to the technical scheme provided by the embodiment, the cotton velvet product is firstly flattened, so that the filling amount of cotton velvet in each area can be analyzed by detecting the thickness of the cotton velvet product. In the detection mechanism 4 of the present embodiment, since the difference of the spot size is mainly caused by the shielding of the filling material to the light in different degrees when the dot matrix laser is irradiated, the difference of the shielding effect is directly related to the filling amount of the cotton wool filled inside. Therefore, the thickness of the cotton velvet product can be estimated by analyzing the size of the light spot, and the cotton velvet filling amount of different areas can be distinguished.

For example, the spot sizes of the irradiated surface of the lint product of this embodiment include 3 kinds, which are 1mm,3mm and 4mm. The specific distribution position is shown in fig. 7 (b). According to a preset rule, the sparse level and the light spot size are in negative correlation. I.e. the larger the spot represents the lower the lint filling, the lower the corresponding sparsity level. Finally, after the light spots in each partition are scored, the light spot size is 1mm, the sparse level score is N4, the light spot size is 3mm, the sparse level score is N2, the light spot size is 4mm, and the sparse level score is N1. Then, the different adjacent equal fraction regions are combined to obtain the final lint distribution pattern as shown in FIG. 7 (c).

The (multi-column) dot matrix laser provided by the embodiment can acquire the detection result in the whole product in one detection. In fact, in other embodiments, a single-row light source may be used to "scan" the target to be detected, and similar technical effects may be achieved.

In the second embodiment, as shown in fig. 8, the light source system and the image capturing device are both located above the lint product to be detected loaded on the conveying mechanism 2. The light source system uses a linear laser light source 43, and when the linear laser light source 43 works, a plurality of parallel light beams with equal intervals are projected on the surface of the cotton velvet product. The image capture device still selects camera 42.

The detection idea of the second scheme and the first scheme is approximately the same, and the filling quantity difference of different areas of the cotton wool product is evaluated by detecting the thickness of the cotton wool product. The difference lies in that the measurement principle of the scheme two is as follows: a projection system projects a plurality of images of equally spaced parallel line arrays to a base surface, and when the surface of the projection base surface is flat, the projected parallel lines still keep parallel under a specific viewing angle. When the projection base plane is uneven, the projected parallel lines are bent under the visual angle, the lines of the protruding parts of the base plane are also convex, and the concave parts of the convex surface are also concave. Meanwhile, the deformation degree of the parallel lines is positively correlated with the deformation amplitude of the concave surface or the convex surface.

The two-way linear laser light source 43 projects an image of the parallel line array to the surface of the lint product to be detected, and the camera 42 arranged on the same side is used for acquiring the deformation condition of the parallel line array under the visual angle. And the image analysis system analyzes the sparsity level of different partitions of the cotton velvet product according to the deformation condition. The image analysis system of the second scheme is approximately the same as the working process of the first scheme, and the specific process is as follows: the image analysis system firstly carries out standardized zoning on the cotton velvet product according to a preset zoning rule; then, performing sparse grade scoring on each partition according to the deformation state of the parallel laser beams in the picture of the upper surface of the cotton velvet product, which is acquired by the image acquisition device; and finally, combining the adjacent partitions with the same sparse level to obtain the required cotton velvet distribution state diagram.

In other embodiments, a sensor (e.g., an infrared sensor) may be disposed at the laser generator in each dot matrix laser source 41, and the sensor is used to detect whether there is a lint shield above the sensor and control the laser generator to turn on only when there is a lint shield. After the controllable light-emitting dot-matrix laser light source 41 is adopted, a large enough laser light source can be installed in the machine table, and then when the detection is carried out on the cotton velvet products with different shapes and sizes, the light-emitting state of each light-emitting point is adjusted. The adaptability of a single device to different cotton velvet products is improved.

It should be noted that, in a specific device, the distribution of the filling material of the cotton linter product can be detected by adopting one of the first scheme and the second scheme according to requirements. And two sets of equipment can be simultaneously installed, and comprehensive evaluation is performed according to the results respectively detected by the two sets of equipment, so that the distribution condition of the fillers in the cotton velvet product can be accurately detected.

As described above, the flattening mechanism 3 in the AI lint intelligent leveling device is not a necessary mechanism when processing lint products with different thicknesses. For example, when the dot matrix laser light source 41 of the first embodiment is used for irradiation and the lint product is thin, the flattening mechanism 3 may not be used. At this time, even if the flattening mechanism 3 is removed from the whole apparatus, it still falls within the protection scope of the related apparatus provided by the present application.

This embodiment, which relies on the light permeability of the lint facing material to work to "halate" a near circular spot on the surface of the material, is effective with most facing materials used for textiles. However, for a cotton velvet product using an opaque material as a fabric (for example, a part of a down jacket will use an opaque waterproof fabric), the cotton velvet filling amount can be detected by using the second scheme.

The camera 42 used in the present embodiment may be a camera 42 based on a CMOS sensor, or may be a camera 42 based on CCD odor. In addition, the 3D camera 42 that can acquire the depth information of the photographic subject may be directly used as a required image pickup device, and when the 3D camera 42 is used, it may not be necessary to install a light source system using a laser. Namely: and 3D cameras are used for simultaneously replacing the light source system and the image acquisition device in the first scheme and the second scheme. Generally, the 3D camera needs to be mounted in an upper position facing the plane to be detected.

In the intelligent cotton velvet beating device provided by the embodiment, after the cotton velvet product is detected in the distribution state of the filler, the dynamic beating process is performed. The dynamic beating refers to selectively beating, and carrying out multi-beating and repeated beating on the area with high cotton wool filling amount; little or no pat is taken for areas with low lint loading. The patting mechanism 5 in this embodiment is configured to selectively patt different sub-areas of the detected lint article on the conveyor mechanism 2 in response to receiving a patting command.

The tapping mechanism 5 is specifically configured as shown in fig. 9, and includes a beater 51, a driving device, and a displacement device. The beater 51 is mounted on a driving device, and the driving device is used for driving the beater 51 to execute beating action according to a preset frequency; the driving mechanism is mounted on a displacement device for adjusting the position of the landing point of the beater 51 when performing a beating action. The shape of the beater 51 in fig. 9 is similar to a cane for beating a quilt when the quilt is sunned at home, and the beater 51 may take other shapes in other embodiments, even a bionic palm shape, etc.

In fig. 9, the driving device is a lever structure with a return spring 54, the lever 52 is made of ferromagnetic material, one end of the lever 52 is hinged on a beater base 53, and the other end is fixedly connected with the beater 51. A return spring 54 is arranged on the surface of the beater base 53; the return spring 54 abuts the lever 52 which is dropped. The surface of the beater base 53 is also provided with an electromagnet 50, after the electromagnet 50 is electrified, the generated magnetic force can adsorb the lever 52, so as to drive the beater 51 at the front end to strike the cotton wool product below, and meanwhile, the return spring 54 is compressed. When the electromagnet 50 is de-energized, the magnetic field disappears and the lever 52 springs upward under the action of the return spring 54. The shape of the lever 52 can be adaptively designed according to the usage scenario, for example, the lever 52 used in this embodiment is in a shape of "7", and in other embodiments, other shapes, such as a "Z", may also be used.

In the tapping mechanism 5 of the present embodiment, by adjusting the on/off state of the electromagnet 50, tapping operations with different frequencies can be realized. The displacement device in this embodiment is a linear motor 55, the beater base 53 is mounted on the linear motor 55, and the linear motor 55 is equivalent to a sliding rail, and can be used to adjust the beating position of the beater 51.

It should be emphasized that the technical solution of the present embodiment does not limit the specific structure and principle of the flapping mechanism 5. For example, although the present embodiment employs a magnetic control scheme, in other embodiments, the lever 52 is driven by a motor to rotate, so as to perform a corresponding flapping action, or an electric cylinder is used to perform a flapping action, which is one of the feasible ways in the present application.

As shown in fig. 10, the tapping mechanism 5 of the present embodiment is installed above the conveying mechanism 2 and arranged in a direction perpendicular to the conveying direction of the conveying belt. Therefore, when the conveyer belt is conveyed forward, the linear motor 55 drives the beater 51 to move horizontally along the direction perpendicular to the conveying direction, so as to beat different areas of the cotton velvet product in sequence, and thus, the cotton velvet product can be accurately beaten. The embodiment provides a solution in which the beating mechanism 5 beats the lint product in a "transverse scanning" manner.

Of course, based on the same technical concept in the present disclosure, in other embodiments, the driving device and the displacement device of the patting mechanism 5 may even be designed as a mechanical arm with multiple degrees of freedom or a truss-like mechanical arm, so as to perform precise patting on the lint product in all directions without depending on the conveying condition of the conveyor belt.

In the present embodiment, the controller 6 is connected in communication with the conveying mechanism 2, the flattening mechanism 3, the detecting mechanism 4, and the tapping mechanism 5, respectively. The controller 6 is a control center of each mechanism, and is equivalent to an upper computer for coordinating the working modes of each mechanism. In this embodiment, the controller 6 is a control cabinet having a plurality of buttons and meters and a display screen on the surface of the device of fig. 2 and 3. The equipment management personnel can coordinate the running state of each mechanism through the controller 6, and then guarantee that whole equipment can carry out accurate patting in automation to the cotton velvet goods of input. Specifically, the operation of the controller 6 includes the following two parts:

(1) And adjusting the working states of the conveying mechanism 2 and the flattening mechanism 3.

(2) Acquiring a lint distribution state diagram output by the detection mechanism 4, generating a corresponding beating strategy according to the sparse level of each partition in the lint distribution state diagram, and then issuing a corresponding beating instruction to the beating mechanism 5 according to the beating strategy.

It is to be emphasized that: in the beating strategy generated by the controller 6, beating is performed only on the regions of the lint product having a higher sparseness level than the median value, or the beating frequency and/or beating times of each partition are positively correlated with the sparseness level. Namely: the beating is performed with a high weight in a region where the cotton linter filling amount is high, and with a small or no beating in a region where the cotton linter filling amount is low. The generation method of the tapping strategy may be programmed by a technician according to preset rules and then automatically generated by a computer program running in the controller 6 without manual intervention.

As can be seen from fig. 10, the solution of the present embodiment actually includes two sets of detecting mechanisms 4, and the two sets of detecting mechanisms 4 are disposed at intervals on the conveying mechanism 2. The purpose of this design is: the former group of detection mechanism 4 can detect the filler distribution state of the cotton linter product of input, and then establishes the data base for 'dynamic beating' in the later period. And the latter group of detection mechanisms 4 is used for carrying out secondary detection on the beaten cotton linter product, and judging whether the beaten fillers are uniformly distributed or not, and the detection result of the latter detection mechanism 4 can be used as a basis for evaluating whether the generated beating strategy is appropriate or not.

In order to improve the flapping effect of the device provided by this embodiment, a flapping strategy generation model designed based on an artificial intelligence algorithm is also run in the controller 6 of this embodiment; and the controller 6 performs iterative optimization on the beating strategy generation model according to the fed back beating effect after each beating. The beating strategy generated by the beating strategy generation model is more efficient and accurate.

For example, in the present embodiment, a reinforcement learning algorithm is adopted to set up the required beating strategy generation model. Reinforcement learning is a Sequential Decision Making (Sequential Decision Making) problem that requires the continuous selection of behaviors from which the greatest benefit is obtained as the best result. Under the condition that a related label of the optimal decision is not obtained, the method tries to do some behaviors and obtains a result, and then optimizes the previous behaviors by judging whether the result is right or wrong. In the process of continuous optimization, the algorithm can learn the optimal beating decision.

In the more optimized scheme of the intelligent uniform cotton velvet beating device, the intelligent uniform cotton velvet beating device further comprises at least one group of heating mechanism 7, and the heating mechanism 7 and the beating mechanism 5 are located in the same area of the intelligent uniform cotton velvet beating device. The heating mechanism 7 is used for heating the lint product while the beating mechanism 5 beats the lint product. The cotton velvet product is heated, the humidity of the filling material in the cotton velvet product can be effectively reduced, the beating process enables the filling material, the packaging material and the beating mechanism 5 to be in charge transfer due to contact and friction, and the cotton velvet product becomes fluffy due to electrostatic action, so that a better even beating effect is generated.

The heating means 7 used in this embodiment is specifically configured, as shown in fig. 5, to include a high-pressure fan 72, a bellows located below the mesh conveyor, and a heating rod 71 located in the bellows, wherein the high-pressure fan 72 feeds an outside air flow into the bellows, and the heating rod 71 heats the air flow and discharges the air flow from a gap in the upper mesh conveyor to heat the lint product above the conveyor.

In the intelligent cotton velvet uniform beating equipment provided by the embodiment, the cotton velvet product is flattened in a vacuum treatment mode; the negative pressure exhaust device used when the flattening mechanism 3 performs vacuum treatment and the high pressure fan 72 used in the heating mechanism 7 are the same equipment. The air flow extracted during the front end vacuum treatment is pumped into the bellows of the rear section heating mechanism 7, and the lint product is sufficiently dried by blowing hot air to the lint product. The design can effectively reduce the overall power consumption of the equipment in the operation process, and has very outstanding economic value.

It should be noted that: the device model provided by the scheme is mainly limited by the volume limit of the whole device, so that a compact and single structure is adopted. In other schemes, the conveying mechanism 2 can be extended, and a plurality of groups of flattening mechanisms 3, detection mechanisms 4, beating mechanisms 5 and heating mechanisms 7 are arranged on the conveying belt in sequence. And all the mechanisms are sequentially arranged along the conveying direction of the conveying mechanism 2 according to the same arrangement sequence, so that the corresponding procedures of flattening, detecting and dynamic beating are repeated, and the single cotton velvet product is beaten in multiple rounds.

Of course, on the premise of adopting the same treatment process, the mechanisms in the automatic intelligent lint leveling machine provided by the embodiment can also be deployed in a manner completely different from the scheme shown in the figure.

For example: the conveying mechanisms 2 can be arranged in an open field to form one or more production lines, then all the mechanisms are respectively arranged along the conveying direction of the production lines, corresponding treatment procedures are respectively executed after the cotton wool products to be treated reach all the stations, and finally, fillers in the cotton wool products are uniformly beaten. The aforementioned processing mechanisms can be selected from different types, and can be optimally selected according to needs, and the like.

Example 2

On the basis of embodiment 1, this embodiment further provides a method for leveling a cotton velvet product, which is a treatment process of the intelligent cotton velvet leveling device provided in embodiment 1 in the product design stage. The embodiment is only one method that can implement the process, and the skilled person can also design other relevant devices to implement the process.

Specifically, as shown in fig. 11, the method for leveling a cotton linter product provided by this embodiment includes the following steps:

s1: standardized zoning is performed on the cotton velvet product.

S2: irradiating along one side of the flattened cotton velvet product by a dot matrix laser source, and acquiring a light spot distribution image on the surface of the cotton fabric on the other side of the cotton velvet product.

S3: performing sparse grade scoring on each standardized partition according to the size of the light spots in the light spot distribution image; thereby generating a lint distribution state diagram.

In the grading process, the larger the spot size, the lower the filling amount of the cotton wool representing the cotton wool product is, and the lower the sparse grade grading value of the corresponding subarea is.

In the beating process, the beating times or frequency of the regions with higher sparse levels are higher, and the regions with sparse levels lower than the median value do not beat.

S5: and (4) circularly executing the steps S1-S3, evaluating the uniform beating effect according to the cotton velvet distribution state diagram, finishing the uniform beating work of the cotton velvet product if the evaluation is qualified, and returning to the step S4 to continue beating and adjusting the beating strategy at the same time if the evaluation is not qualified.

For some thicker cotton velvet products, in order to ensure that light spots generated under the laser irradiation condition are clear and visible, the operations of exhausting and flattening the cotton velvet products can be added before the step S1.

In addition, the process of steps S3-S4 in the above process is used for detecting the filling amount of the lint, and the detection method can be modified into other manners, for example, the present implementation also provides another scheme after the modification of steps S3-S4. Specifically, in another aspect, the method for leveling a cotton linter product specifically includes the following steps as shown in fig. 12:

s1: the air is removed from the lint product to be treated so that the lint product is completely unfolded and flattened.

S2: standardized zoning is performed on the cotton velvet product.

S3: the flattened cotton velvet product is irradiated along one side by a parallel line bundle type light source so as to project a plurality of equally spaced parallel light rays on the surface of the cotton velvet product and collect light ray distribution images at the same side of the cotton velvet product.

S4: performing sparse grade scoring on each standardized partition according to the deformation state of the parallel light; and then a lint distribution state diagram is generated.

In the grading process, the bigger the convex amplitude of the light is, the higher the filling amount of the cotton velvet representing the cotton velvet product is, and the higher the sparse grade grading value of the corresponding subarea is. The larger the light sinking amplitude is, the lower the filling amount of the cotton wool representing the cotton wool product is, and the lower the sparse grade score value of the corresponding subarea is.

S5: beating the area with the sparsity level higher than the median value in each subarea of the cotton velvet product according to the cotton velvet distribution state diagram, and/or heating the cotton velvet product while beating.

S6: and (5) circularly executing the steps S1-S4, evaluating the uniform beating effect according to the cotton velvet distribution state diagram, finishing uniform beating work of the cotton velvet product if the cotton velvet distribution state diagram is qualified, and returning to the step S5 to continue beating and simultaneously adjusting beating strategies if the cotton velvet distribution state diagram is not qualified.

The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
