Technical Field

Background

Many clothing, household articles and artworks need to be filled with fillers such as cotton, down or chemical fibers to achieve the effects of heat preservation, shock absorption or modeling, and the products are called as cotton velvet products. Such as quilts, down jackets, plush toys, sofas, cushions, etc., are all common cotton linters. Large pieces of cotton linter product may have uneven filling problems during the manufacturing process. At this time, the product needs to be beaten so that the lint is uniformly distributed in the packaging material. At present, when cotton velvet products of many small textile processing enterprises are processed, the traditional manual beating method is still used for beating cotton velvet evenly, and the cotton velvet product beating method is time-consuming and labor-consuming and has low efficiency. In addition, when a worker performs a flapping work for a long time, the worker is liable to cause damage to the shoulder, waist and the like.

In order to improve the uniform beating efficiency of cotton linters, various cotton beating machines are developed for enterprises. The cotton beating machine is bionic equipment and can replace manual beating of the surface of a cotton velvet product repeatedly. Further greatly improving the uniform beating efficiency of the cotton velvet product, saving the labor cost and solving the problem of labor injury of workers. But is not limited to. Such traditional machine of beating fine hair can't discern the packing distribution state of cotton velvet goods usually, consequently only can carry out whole beating, can't carry out accurate beating to cotton velvet pile up the region, consequently the effect of beating work still is relatively poor, still has the inhomogeneous condition of cotton velvet distribution after beating. In addition, such devices typically consume relatively high energy because the indifferent flapping process extends the operating time of the device. Part of beating machines also need to manually move and turn over the cotton velvet products, the automation degree of the equipment is low, and the use cost is relatively high.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Example 1

The embodiment provides an AI cotton velvet intelligent beating device which is used for beating cotton velvet products filled with cotton velvet inside so as to enable the fillers inside the cotton velvet products to be evenly distributed. As shown in fig. 1 and fig. 2, the product of the intelligent cotton linter homogenizing device provided in this embodiment is a small horizontal machine. Comprises a 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 frame 1. The surface of the frame 1 is also covered with a plurality of sealing cover plates, and the cover plates can protect the internal mechanisms and prevent the treatment mechanisms from being damaged due to exposure to the external environment.

Wherein the conveying mechanism 2 is used for sequentially conveying the cotton velvet products to be treated to a treatment mechanism for executing different procedures at the later stage. In the present embodiment, the conveying mechanism 2 may employ any one of a belt conveyor, a plate conveyor, a mesh belt conveyor, and a dolly conveyor. Because the embodiment provides a small product, the conveying mechanism 2 is a mesh belt conveyor, as shown in fig. 3, the conveying belt of the mesh belt conveyor provided by the embodiment is arranged along the vertical direction, four sides are respectively tensioned through multiple groups of chain wheels, and the two groups of motors drive the chain wheels to rotate so as to realize conveying of the conveying belt. The conveying belt provided by the embodiment provides a conveying table along a horizontal plane, and the cotton velvet product to be treated is input from one side of the conveying table and is output from the other side after being tapped. Meanwhile, in a vertically arranged conveying belt, the space above and below the conveying table top can be used for installing various related devices, so that the limited equipment internal space is fully utilized.

Of course, in other embodiments, other types of conveyors may be used, and the layout of the flattening mechanism 3, the detecting mechanism 4, the beating mechanism 5, etc. may be adaptively adjusted when the type and layout of the conveyors are changed.

The cotton velvet intelligent beating device has the main advantages that different areas of the cotton velvet product can be selectively and accurately beaten according to the distribution state of the fillers in the cotton velvet product, so that the cotton velvet in the cotton velvet product can be rapidly and uniformly distributed, and invalid beating is avoided. The precondition for realizing fine beating is that the distribution state of the filling in the cotton velvet product needs to be detected.

In order to accurately detect the distribution state of the filling material in the cotton velvet product, the input cotton velvet product is preprocessed by the flattening mechanism 3, so that air in the cotton velvet product is extruded, and the surface of the cotton velvet product is flattened. The distribution condition of the filling material of the cotton velvet product can be accurately detected when the cotton velvet product is flattened and extruded in the air, so that the problem that the appearance difference between a high-density area and a low-density area of the filling material is small and cannot be accurately distinguished is solved under the fluffy state of the filling material.

It is emphasized that; the flattening mechanism 3 is not an essential mechanism of the intelligent cotton velvet beating device provided by the implementation. For example, in the case of filling level detection for some thin or light-transmitting lint products, the product may not be flattened. The flattening mechanism 3 is not required to be arranged in the corresponding homogenizing equipment.

Various technical schemes can be adopted for realizing the flattening of the cotton velvet product; in this embodiment, the flattening mechanism 3 adopts a negative pressure exhaust device to flatten the lint product. Specifically, as shown in fig. 4 and 5, in this embodiment, a negative pressure exhaust device is disposed right under the front side of the conveying table, the air inlet of the negative pressure exhaust device is located at a position facing the upper conveying belt, and the air inlet is surrounded by a plurality of partition plates to form a fan housing 31. Because the conveyer belt adopted in the embodiment is net-shaped and has good air permeability, after the cotton velvet product to be treated is covered above the fan housing 31 at the air inlet of the negative pressure exhaust device, the negative pressure exhaust device can perform vacuum suction on the upper part of the conveyer belt, and then a negative pressure area is formed locally, and air in the cotton velvet product is extracted, so that the cotton velvet product is automatically flattened by atmospheric pressure.

In addition, in other embodiments, the flattening mechanism 3 may also employ a flat extruder, a twin-roll extruder, or the like. The flat plate extruder extrudes the cotton velvet product through a pair of flat plate lifting mechanisms arranged up and down on the conveying belt, and the cotton velvet product is flattened. The twin-roll extruder presses the lint product by a pair of rollers disposed above the conveyor belt, thereby "flattening" the lint product. The double-roller type extruder comprises two rollers which are arranged in parallel up and down, a gap is arranged between the two rollers and the rollers rotate reversely, so that the input cotton velvet product is fully extruded into a flat shape. The three flattening mechanisms 3 can be optimized according to different designs. Or a plurality of flattening mechanisms 3 can be simultaneously adopted in the same equipment, and related devices such as vacuum suction and roll extrusion can be installed at the same time. In addition, in other embodiments, other devices may be used for the flattening process, as long as the device can flatten the lint product along its development.

After the flattening treatment, the intelligent cotton velvet discharging device detects cotton velvet filling amounts of different areas in the flattened cotton velvet product through the detecting 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 detected linear or matrix beam of light toward the surface of the lint article. 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 generating sparse grades corresponding to each partition according to the state of the light rays or the light spots to obtain a cotton velvet distribution state diagram. Wherein the sparsity level is a custom physical quantity that characterizes the lint loading of the current partition.

The detecting mechanism 4 is a core mechanism in the present embodiment, and the main function of the mechanism is to detect the filling amount of lint inside the lint product inputted on the conveying mechanism 2. The present embodiment provides two schemes for detecting the filling amount of the lint respectively.

In the first embodiment, as shown in fig. 6, the light source system and the image acquisition device are respectively located on 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 a 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 this embodiment is perpendicular to the lint product on the conveyor belt. When the cotton linter product passes through the detection area of the detection mechanism 4, the light source system starts to operate, and at this time, the lattice type laser light source 41 irradiates the cotton linter product, so that a plurality of light spots uniformly distributed on the surface are formed. At this point, the camera 42 begins to take a picture and acquires an image of the upper surface of the underlying lint product in which the projected spots are evenly distributed on the surface of the lint product. In this embodiment, the light source system uses a laser light source, and in other embodiments, the light source may also use a directional strong light source with collimation.

The image captured by the camera 42 is transmitted to an image analysis system for analysis. The image analysis system performs standardized partitioning on the cotton velvet product according to the distribution positions of the light spots when processing the cotton velvet product, so that each light spot is positioned in the center of the partition. Then, carrying out sparse grade grading on each partition according to a preset 'spot diameter-sparse grade' list; and finally, merging adjacent subareas with the same sparse level to obtain the required cotton velvet distribution state diagram.

Specifically, the workflow of the image analysis system is approximately shown in fig. 7, and the light spot distribution of a flattened pillow-like lint product after being irradiated by the lattice laser light source 41 is approximately shown in fig. 7. The image analysis system first performs standardized partitioning of the lint product, in this embodiment, the standardized partitioning map is generally shown in fig. 7 (a). It can be seen that the throw pillow is divided into 24 partitions of 4 x 6, where the partitions may be coded, for example, as A1B1, A1B2, A1B3, A1B4 … … A6B1, A6B2, A6B3, A6B4, respectively, on the abscissa. The aim of coding in the step is to position different areas of the cotton velvet product when the beating action is executed in the later stage, so that accurate beating is realized.

Next, the image analysis system detects the size of the spot within the partition again. The technical scheme provided by the embodiment is to collapse the cotton velvet product first, so that the cotton velvet filling quantity of each area can be analyzed by detecting the thickness of the cotton velvet product. In the detection mechanism 4 of the present embodiment, the difference in spot size is mainly caused by the shielding of the filler to different degrees of light during the dot matrix laser irradiation, and the difference in shielding effect is directly related to the filling amount of the cotton linters 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 quantity of different areas can be distinguished.

For example, the spot sizes of the irradiated surfaces of the cotton linters product of this example include 3 kinds, which are classified into 1mm,3mm and 4mm. The specific distribution position is shown in fig. 7 (b). According to a preset rule, the sparse level and the spot size are inversely related. I.e., the larger the flare represents the lower the lint loading, the lower the corresponding sparsity rating. Finally, after scoring the spots in each zone, the spot size was 1mm, the sparse level score was N4, the spot size was 3mm, the sparse level score was N2, the spot size was 4mm, and the sparse level score was N1. And combining different adjacent equivalent areas to obtain the final cotton linter distribution state diagram as shown in fig. 7 (c).

The (multi-column) lattice type laser provided by the embodiment can obtain the detection result in the whole product in one detection. In fact, in other embodiments, a single-column 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, both the light source system and the image acquisition device are located above the lint product to be detected loaded on the conveying mechanism 2. The light source system adopts 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 acquisition device still selects the camera 42.

The detection concept of the second scheme is almost the same as that of the first scheme, and the filling quantity difference of different areas of the cotton velvet product is evaluated by detecting the thickness of the cotton velvet product. The difference is that the measurement principle of the scheme II is as follows: an image of a plurality of equally spaced parallel line arrays is projected onto a base surface by a projection system, and when the surface of the projected base surface is smooth, the projected parallel lines will remain parallel at a particular viewing angle. When the projection base surface is uneven, each projected parallel line will bend under the aforementioned viewing angle, the line of the protruding part of the base surface will also be convex upward, and the concave part of the convex surface will also be concave downward. While the degree of deformation of the parallel lines is positively correlated with the magnitude of deformation of the concave or convex surfaces.

The two-way linear laser source 43 projects an image of the parallel line array onto the surface of the cotton linter product to be detected, and the deformation condition of the parallel line array under the viewing angle is acquired by the camera 42 arranged on the same side. The image analysis system analyzes the sparse grades of different areas 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 partitioning on the cotton velvet product according to a preset partitioning rule; then, carrying out sparse grade grading on each subarea according to the deformation state of the parallel laser beams in the picture of the upper surface of the cotton velvet product obtained by the image acquisition device; and finally, merging adjacent subareas 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 provided at the laser generator in each of the lattice laser sources 41 to detect if there is a lint product shielding above and to control the laser generator to be turned on only if there is shielding. After the controllable luminous dot matrix laser light source 41 is adopted, a sufficiently large laser light source can be installed in the machine, and then the luminous state of each luminous point can be adjusted when cotton velvet products with different shapes and different sizes are detected. The adaptability of a single device to different cotton linter products is improved.

It should be noted that, in a specific apparatus, one of the first and second schemes may be used to detect the distribution of the filling material of the lint product as needed. Two sets of equipment can be installed simultaneously, comprehensive evaluation can be carried out according to the results detected by the two sets of equipment respectively, and the distribution condition of the filling materials in the cotton velvet product can be detected more accurately.

As mentioned above, the flattening mechanism 3 in the AI lint intelligent evening device is not a necessary mechanism when handling lint products of different thickness. 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 relevant apparatus provided in the present case.

The first embodiment needs to work by relying on the light transmittance of the cotton velvet product fabric to 'halate' a nearly circular light spot on the surface of the material, which is effective for most fabrics used in textiles. However, for the cotton velvet product using the light-proof material as the fabric (for example, a part of the down jacket can use the light-proof waterproof fabric), the second scheme can be adopted for detecting the filling amount of cotton velvet.

The camera 42 used in the present embodiment may be a camera 42 based on a CMOS sensor, or a camera 42 based on a CCD odor. In addition, the 3D camera 42 that can acquire the depth information of the photographing object may be directly employed as a required image pickup device, and when the 3D camera 42 is employed, a light source system employing a laser may not be required to be installed. Namely: the light source system and the image pickup device in the first and second alternatives are simultaneously replaced with a 3D camera. Typically, a 3D camera needs to be mounted in a position just above the plane to be detected.

In the intelligent cotton velvet beating device provided by the embodiment, after the cotton velvet product completes the detection of the distribution state of the filling material, the process of 'dynamic beating' is performed. "dynamic slapping" means selectively slapping, multiple slapping and re-slapping of areas with high lint filling; little or no beat is taken for areas with low lint loading. The beating mechanism 5 in this embodiment is used for selectively beating different sections of detected lint product on the conveying mechanism 2 according to a received beating command.

The specific structure of the flapping mechanism 5 is shown in fig. 9, and includes a flappers 51, a driving device, and a displacement device. The beater 51 is mounted on a driving device for driving the beater 51 to perform a beating action according to a preset frequency; the driving mechanism is mounted on a displacement device for adjusting the landing position of the flapper 51 when the flapping motion is performed. The shape of the beater 51 in fig. 9 is similar to a cane for beating a quilt when the quilt is shone for home use, and in other embodiments, the beater 51 may take other shapes, 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. The surface of the beater base 53 is provided with a return spring 54; the return spring 54 abuts against the falling lever 52. The surface of the beater base 53 is also provided with an electromagnet 50, and after the electromagnet 50 is electrified, the generated magnetic force can adsorb the lever 52, so that the beater 51 at the front end is driven to beat down the cotton velvet product, and meanwhile, the reset spring 54 is compressed. When the electromagnet 50 is de-energized, the magnetic field is removed and the lever 52 springs upward under the action of the return spring 54. The shape of the lever 52 may be adaptively designed according to the use situation, for example, the lever 52 adopted in the present embodiment is in a shape of "7", and in other embodiments, other shapes may be adopted, for example, a shape of "Z", etc.

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

It should be emphasized that the specific structure and principle of the beating mechanism 5 are not limited by the technical solution of the present embodiment. For example, although the magnetic control scheme is adopted in this embodiment, in other embodiments, the motor drives the lever 52 to rotate to perform the corresponding beating action, or the electric cylinder is used to perform the beating action, which is one of the possible ways of this application.

As shown in fig. 10, the tapping mechanism 5 of the present embodiment is installed above the conveying mechanism 2 and is arranged in a direction perpendicular to the conveying direction of the conveying belt. Therefore, when the conveyor belt is conveyed forward, the linear motor 55 drives the beater 51 to translate along the direction perpendicular to the conveying direction, and the different areas of the lint product are sequentially beaten, so that accurate beating of the lint product can be realized. The beating mechanism 5 in the solution provided in this embodiment adopts a "transverse scanning" way to beat the lint product.

Of course, based on the same technical concept in the present case, in other embodiments, the driving device and the displacement device of the beating mechanism 5 may even be designed as a mechanical arm or truss type mechanical arm with multiple degrees of freedom, so as to implement omnibearing and precise beating of the lint product under the condition of not depending on the conveying of the conveying belt.

In this embodiment, the controller 6 is communicatively connected to the conveying mechanism 2, the flattening mechanism 3, the detecting mechanism 4, and the flapping mechanism 5, respectively. The controller 6 is a control center of each of the above mechanisms, and corresponds to an upper computer for coordinating the operation modes of each mechanism. In this embodiment, the controller 6 is a control cabinet with many buttons, meters and display screens on the surface of the device in fig. 2 and 3. The equipment manager can coordinate the running states of all mechanisms through the controller 6, so that the whole equipment can automatically and accurately flap the input cotton velvet product. Specifically, the operation content of the controller 6 includes the following two parts:

(1) The working states of the conveying mechanism 2 and the flattening mechanism 3 are adjusted.

(2) And acquiring a cotton velvet distribution state diagram output by the detection mechanism 4, generating a corresponding beating strategy according to the sparse level of each partition in the cotton velvet distribution state diagram, and then giving a corresponding beating instruction to the beating mechanism 5 according to the beating strategy.

It is emphasized that: in the beating strategy generated by the controller 6, only the area with the sparse level higher than the median value in the cotton linter product is beaten, or the beating frequency and/or the beating times of each partition are in positive correlation with the sparse level. Namely: the method mainly comprises the steps of beating areas with high cotton velvet filling quantity, and beating or not beating areas with low cotton velvet filling quantity. The generation method of the tapping strategy can 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 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 to: the former group of detection mechanisms 4 can detect the distribution state of the filling material of the input cotton velvet product, and further lay a data foundation for 'dynamic beating' in the later stage. The latter group of detection mechanisms 4 is used for performing secondary detection on the batting products after being beaten, judging whether the batting fillers are uniformly distributed, and the detection result of the latter group of detection mechanisms 4 can be used as a basis for evaluating whether the generated beating strategy is proper or not.

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

For example, in the present embodiment, a model is generated using a beating strategy required for the reinforcement learning algorithm setup. Reinforcement learning is a sequential decision (Sequential Decision Making) problem that requires the continuous selection of actions from which the greatest benefit is obtained as best results. It attempts to make some actions and get a result without obtaining the relevant label for the best decision, and then optimizes the previous actions by judging whether the result is correct or incorrect. In the process of continuous optimization, the algorithm can learn the optimal tapping decision.

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

The specific structure of the heating mechanism 7 adopted in this embodiment is shown in fig. 5, and includes a high-pressure fan 72, a bellows located below the mesh conveyor belt, and a heating rod 71 located in the bellows, wherein the high-pressure fan 72 sends external air flow into the bellows, and the heating rod 71 heats the air flow and is discharged from a gap in the mesh conveyor belt above for heating the lint product above the conveyor belt.

In the intelligent cotton velvet beating equipment provided by the embodiment, cotton velvet products are flattened in a vacuum treatment mode; the negative pressure exhaust device adopted in the vacuum treatment of the flattening mechanism 3 and the high-pressure fan 72 adopted in the heating mechanism 7 are the same set of equipment. The air flow drawn out during the front end vacuum treatment is pumped into the bellows of the rear stage 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 in the running process of the equipment, and has very outstanding economic value.

It should be noted that: the device model provided by the above illustrated solution is limited mainly by the bulk of the whole device, thus adopting a relatively compact and single structure. In other schemes, the conveying mechanism 2 can be prolonged, and a plurality of groups of flattening mechanisms 3, detection mechanisms 4, beating mechanisms 5 and heating mechanisms 7 are sequentially arranged on the conveying belt. And the mechanisms are sequentially arranged along the conveying direction of the conveying mechanism 2 according to the same arrangement sequence, so that the corresponding flattening-detecting-dynamic beating procedures are repeated, and single cotton velvet products are beaten in multiple rounds.

Of course, on the premise of adopting the same treatment process, all the mechanisms in the automatic cotton linter intelligent homogenizer provided by the embodiment can be deployed in a mode completely different from the scheme shown in the drawings.

For example: the conveying mechanism 2 can be installed in an open field to form one or more production lines, then each mechanism is respectively distributed along the conveying direction of the production lines, the cotton velvet products to be treated respectively execute corresponding treatment procedures after reaching each station, and finally, the fillers in the cotton velvet products are uniformly beaten. The aforementioned processing mechanisms may be selected to be different types, may be optimally selected as desired, etc.

Example 2

On the basis of the embodiment 1, the embodiment further provides a cotton velvet product beating and homogenizing method, which is the treatment process of the cotton velvet intelligent beating and homogenizing equipment provided in the embodiment 1 in the product design stage. The embodiments are just one of the ways in which the process may be performed, and other related equipment may be devised by the skilled person to perform the process.

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

s1: standardized zoning of the cotton linter product is performed.

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

S3: sparse grade grading is carried out 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 scoring process, the larger the spot size, the lower the lint loading of the lint product, and the lower the sparse rating score of the corresponding partition.

In the beating process, the higher the sparse level is, the higher the beating frequency or the frequency is, and the sparse level is lower than the median area and does not beat.

S5: and (3) circularly executing the steps of the steps S1-S3, evaluating the beating effect according to the cotton velvet distribution state diagram, and if the evaluation is qualified, completing the beating work of the cotton velvet product, otherwise, returning to the step S4 to continuously beat, and simultaneously adjusting the beating strategy.

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

In addition, the steps S3-S4 in the above process are used for detecting the filling amount of the cotton linters, and the detection method can be modified in other ways, for example, the implementation also provides another scheme after the steps S3-S4 are modified. Specifically, in another scheme, the cotton velvet product beating method specifically comprises the following steps as shown in fig. 12:

s1: the air in the lint product to be treated is removed so that the lint product is completely spread out and flattened.

S2: standardized zoning of the cotton linter product is performed.

S3: and irradiating along one side of the flattened cotton velvet product by a parallel wire harness type light source so as to project a plurality of equally spaced parallel light rays on the surface of the cotton velvet product and collecting light ray distribution images on the same side of the cotton velvet product.

S4: carrying out sparse grade grading on each standardized partition according to the deformation state of the parallel light rays; thereby generating a lint distribution state diagram.

In the scoring process, the larger the upward protruding amplitude of the light rays is, the higher the filling quantity of the cotton velvet product is, and the higher the sparse grade scoring value of the corresponding partition is. The greater the magnitude of the light sag, the lower the lint loading of the lint product, and the lower the sparse level score of the corresponding partition.

S5: and (3) beating the areas with the sparse grade higher than the median value in each partition of the cotton velvet product according to the cotton velvet distribution state diagram, and/or heating the cotton velvet product while beating.

S6: and (3) circularly executing the steps of the steps S1-S4, evaluating the beating effect according to the cotton velvet distribution state diagram, and if the beating effect is qualified, completing the beating work of the cotton velvet product, otherwise, returning to the step S5 to continuously beat, and simultaneously adjusting the beating strategy.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
