[0002] The current method of spreading fabric can only solve part of the wrinkle problem, that is, the fabric can be spread flat if the wrinkles are not serious.

The spreading roller requires more manual intervention and needs to be manually operated to ensure that the fabric is as flat as possible.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted that the dust removal and flattening mechanism can remove dust and flatten the fabric in the fabric inspection machine. The surface of the fabric produced by the fabric production plant will be adhered to a large number of impurities such as thread and cotton, which will affect the inspection in the quality inspection link, because it is necessary to frequently stop the machine to check whether the impurities are caused by real fabric defects or just adhered. In addition, the overlap of wrinkles on the surface of the fabric will also affect the inspection of the surface quality of the fabric. Therefore, it is necessary to remove the impurities adhering to the surface of the fabric and flatten the wrinkled fabric to facilitate the subsequent process of fabric quality inspection.

[0036] At present, the cloth inspection machine uses two distribution rollers to spread the cloth. The wrinkles on the cloth are flattened by the threaded wire on the roller shaft. There is no suitable dust removal device available for the time being. The current spreading method can only solve part of the wrinkle problem, that is, the cloth can be flattened when the wrinkles are not serious. When the cloth has a large folded area, it is difficult to flatten the cloth in a short time, because the cloth moves from one end to the other at a certain speed. Therefore, if the cloth cannot be completely flattened in a short time, it will not only affect the camera detection results but also affect the flatness of the cloth at the winding end. The current spreading roller shaft requires more manual intervention, and it is necessary to manually ensure that the cloth is as flat as possible, so that the cloth can be flattened better during the movement of the cloth. At the same time, because the current spreading roller shaft rotates in the opposite direction to the movement direction of the cloth, and it must have a relatively tight contact with the cloth, the current distribution roller will have a certain friction on the surface of the cloth. The impact of this friction on the quality of the cloth will increase with the increase of speed. In order to ensure the quality of the cloth, the current maximum detection speed is maintained at about 60m / min. That is to say, the current method of flattening the cloth limits the speed at which the cloth moves from one end to the other, which affects efficiency.

[0037] Reference Figure 1 , shows a structural block diagram of an embodiment of a dust removal and flattening mechanism of the present invention, wherein the dust removal and flattening mechanism is applied to a cloth inspection machine. The cloth inspection machine can be a manual cloth inspection machine, a semi-automatic cloth inspection machine or a fully automatic cloth inspection machine.

[0038] Among them, the basic structure of the manual cloth inspection machine: the manual cloth inspection machine is usually composed of a frame, a yarn stretching device, a lifting device, and floor casters. It is equipped with a cloth inspection table, a light source and lighting device, and a code recording device. Working principle: the operator lays the cloth flat on the cloth inspection table and observes the surface quality of the cloth with the naked eye. The cloth inspection machine automatically completes the length recording and roll arrangement work.

[0039] The basic structure of the semi-automatic cloth inspection machine: The semi-automatic cloth inspection machine adds automated components such as cameras and touch screens on the basis of the manual cloth inspection machine. It is usually equipped with a computer monitor and an automatic measurement system. Working principle: After the operator starts the equipment, the camera will automatically scan the surface of the cloth. When a defect is found, the operator can mark the defect location through the touch screen, and the system will automatically record and generate a cloth inspection report.

[0040] The basic structure of the fully automatic cloth inspection machine: The fully automatic cloth inspection machine integrates a high-definition camera, a high-speed processor and advanced image processing algorithms. It is usually equipped with functions such as automatic feeding, automatic cloth rolling, automatic length counting and automatic quality statistics. Working principle: The fully automatic cloth inspection machine captures the image of the cloth surface through the camera and automatically identifies defects using image processing algorithms. The equipment will automatically complete the entire process of feeding, scanning, identifying and sorting the cloth without manual intervention.

[0041] The dust removal and flattening mechanism may specifically include the following components:

[0042] The first roller 100 and the second roller 200 are arranged at the upper roll end of the cloth inspection machine, and the first roller 100 and the second roller 200 are symmetrically distributed along the cloth;

[0043] A first high-pressure air nozzle assembly 300 is arranged on a side of the first roller 100 away from the upper roll end of the cloth inspection machine, and the included angle between the air jet direction of the first high-pressure air nozzle assembly 300 and the moving direction of the cloth is less than 90 degrees;

[0044] A second high-pressure air nozzle assembly 400 is disposed on a side of the second roller 200 away from the upper roll end of the cloth inspection machine, and the included angle between the air jet direction of the second high-pressure air nozzle assembly 400 and the moving direction of the cloth is less than 90 degrees;

[0045] The first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are symmetrically distributed along the cloth.

[0046] In the embodiment of the present invention, the dust removal and flattening mechanism comprises at least a first roller 100, a second roller 200, a first high-pressure air nozzle assembly 300, and a second high-pressure air nozzle assembly 400. The structures of the first roller 100 and the second roller 200 may be the same, and the structures of the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 may be the same, so that the first roller 100, the first high-pressure air nozzle assembly 300 and the second roller 200, the second high-pressure air nozzle assembly 400 are symmetrical.

[0047] The first roller 100 and the second roller 200 can both be arranged at the upper roll end of the cloth inspection machine, which refers to the part of the cloth inspection machine used to wind and support the cloth to be inspected. The first roller 100 and the second roller 200 are symmetrically distributed along the cloth, and the cloth is output from between the first roller 100 and the second roller 200, and the first roller 100 and the second roller 200 are used to flatten the cloth.

[0048] The first roller 100 and the second roller 200 may be composed of a main shaft, an outer roller sleeve and a protective shell.

[0049] Spindle: The spindle is the core component of the first roller 100 and the second roller 200, and is usually made of high-strength, low-ferromagnetic materials, such as 40Cr steel, 20Cr steel, 20CrMn2B steel or 20CrMnTi low-carbon steel, etc. These materials have good mechanical properties and wear resistance, and can ensure the stability and reliability of the rollers during long-term operation.

[0050] Outer roller sleeve: The outer roller sleeve is the part of the first roller shaft and the second roller shaft 200 that directly contacts the fabric to be tested. The material selection has an important impact on the performance and service life of the roller shaft. Common outer roller sleeve materials include hard alloys (such as tungsten carbide-based alloys, titanium carbide, titanium nitride-based alloys, chromium carbide alloys), high manganese steel, 40Cr, austenitic stainless steel, and non-ferromagnetic materials such as alumina ceramics and zirconia ceramics. These materials have the characteristics of high hardness, high wear resistance and high corrosion resistance, and can meet the processing requirements of different fabrics.

[0051] Protective shell: The protective shell is usually arranged on the four surfaces of the first roller 100 and the second roller 200, and is made of non-ferromagnetic materials, such as PP (polypropylene), PET (polyethylene terephthalate), PA6 (polyamide 6), POM (polyoxymethylene), PBT (polybutylene terephthalate), PS (transparent styrene), ABS (acrylonitrile-butadiene-styrene copolymer) and austenitic stainless steel, etc. The main function of the protective shell is to prevent the magnetic material of the crushing belt from splashing out of the crushing chamber, and at the same time protect the first roller 100 and the second roller 200 from damage by the external environment.

[0052] The first high-pressure air nozzle assembly 300 is arranged on the side of the first roller 100 away from the upper roll end of the cloth inspection machine, and the second high-pressure air nozzle assembly 400 is arranged on the side of the second roller 200 away from the upper roll end of the cloth inspection machine. The angle between the jet direction of the first high-pressure air nozzle assembly 300 and the movement direction of the cloth is less than 90 degrees; the angle between the jet direction of the second high-pressure air nozzle assembly 400 and the movement direction of the cloth is less than 90 degrees; the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are symmetrically distributed along the cloth.

[0053] That is, there is a certain angle between the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 and the movement direction of the cloth, and the angle between the jet direction of the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 and the movement direction of the cloth is less than 90 degrees, so that after the airflow blows on the surface of the cloth, the angle between the movement direction and the running direction of the cloth is less than 90 degrees, and the high-pressure gas ejected by the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 is used to flatten the wrinkles of the cloth.

[0054] The embodiment of the present invention is provided with a first roller 100 and a second roller 200 at the upper roll end of the cloth inspection machine, and the first roller 100 and the second roller 200 are symmetrically distributed along the cloth; a first high-pressure air nozzle assembly 300 is provided at a side of the first roller 100 away from the upper roll end of the cloth inspection machine, and the angle between the jet direction of the first high-pressure air nozzle assembly 300 and the movement direction of the cloth is less than 90 degrees; a second high-pressure air nozzle assembly 400 is provided at a side of the second roller 200 away from the upper roll end of the cloth inspection machine, and the angle between the jet direction of the second high-pressure air nozzle assembly 400 and the movement direction of the cloth is less than 90 degrees; the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are symmetrically distributed along the cloth. The surface of the cloth is quickly flattened by the first roller 100 and the second roller 200, and the dust on the surface of the cloth is removed by the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400, thereby improving the detection efficiency and accuracy of the cloth inspection machine.

[0055] Reference Figure 2 , shows a schematic structural diagram of a dust removal and flattening mechanism embodiment of the present invention, the dust removal and flattening mechanism may specifically include the following components:

[0056] The first roller 100 and the second roller 200 are arranged at the upper roll end of the cloth inspection machine, and the first roller 100 and the second roller 200 are symmetrically distributed along the cloth;

[0057] A first high-pressure air nozzle assembly 300 is arranged on a side of the first roller 100 away from the upper roll end of the cloth inspection machine, and the included angle between the air jet direction of the first high-pressure air nozzle assembly 300 and the moving direction of the cloth is less than 90 degrees;

[0058] A second high-pressure air nozzle assembly 400 is disposed on a side of the second roller 200 away from the upper roll end of the cloth inspection machine, and the included angle between the air jet direction of the second high-pressure air nozzle assembly 400 and the moving direction of the cloth is less than 90 degrees;

[0059] The first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are symmetrically distributed along the fabric;

[0060] An air jet adjustment assembly connected to the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400, and used to adjust the air jet direction of the first high-pressure air nozzle assembly 300 and the air jet direction of the second high-pressure air nozzle assembly 400;

[0061] The dust suction groove 500 is arranged at the upper rolling end of the cloth inspection machine. The dust suction groove 500 is an open structure, and the opening of the opening structure is toward the jet direction of the first high-pressure air nozzle assembly 300 and / or, toward the jet direction of the second high-pressure air nozzle assembly 400.

[0062] In the embodiment of the present invention, the dust removal and flattening mechanism may be composed of a first roller 100, a second roller 200, a first high-pressure air nozzle assembly 300, a second high-pressure air nozzle assembly 400, an air jet adjustment assembly and a dust suction groove 500.

[0063] The first roller 100 and the second roller 200 can be arranged at the upper end of the cloth inspection machine.

[0064] The size of the second roller 200 can be determined according to requirements, and the embodiment of the present invention does not specifically limit this.

[0065] For example, the first roller 100 and the second roller 200 can be smooth rollers, and the roller diameter of the first roller 100 and the second roller 200 is 10 cm and the length is 220 cm. An installation position that can meet the size requirements can be found on the upper roll end of the cloth inspection machine, and the first roller 100 and the second roller 200 are symmetrically distributed along the cloth on the upper roll end of the cloth inspection machine. The central axes of the first roller 100 and the second roller 200 are parallel to each other, and the plane where the center line of the first roller 100 and the second roller 200 is located is perpendicular to the plane of the cloth. The first roller 100 and the second roller 200 are close to the side of the cloth and are parallel to the tangent line of the surface where the cloth is located. Keep a certain distance, such as a distance of 10 cm.

[0066] The first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 can be arranged on the side of the corresponding roller away from the upper roll end of the cloth inspection machine. That is, the first high-pressure air nozzle assembly 300 is arranged on the side of the first roller 100 away from the upper roll end of the cloth inspection machine. The second high-pressure air nozzle assembly 400 is arranged on the side of the second roller 200 away from the upper roll end of the cloth inspection machine. Figure 2 In the embodiment, the first high-pressure air nozzle assembly 300 is located below the first roller 100 , and the second high-pressure air nozzle assembly 400 is located below the second roller 200 .

[0067] The angle between the jet direction of the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 and the movement direction of the cloth is less than 90 degrees, and the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are symmetrically distributed along the cloth, so that the angle between the movement direction of the airflow after blowing on the surface of the cloth and the running direction of the cloth is less than 90 degrees, and the high-pressure gas ejected by the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 is used to flatten the wrinkles of the cloth.

[0068] The plane perpendicular to the first high-pressure air nozzle assembly 300, the second high-pressure air nozzle assembly 400 and the plane where the cloth is located is exactly tangent to the surface of the corresponding roller. The position where the tangent surface and the tangent line of the corresponding roller are located and a certain distance from the roller is the position for installing the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400.

[0069] In an optional embodiment of the present invention, the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 have the same structure, including two rows of high-pressure air nozzle groups arranged along the moving direction of the cloth.

[0070] The first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 have the same structure and are respectively arranged on one side of the cloth. The first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 include two rows of high-pressure air nozzle groups arranged along the moving direction of the cloth.

[0071] Each row of high-pressure air nozzle groups in the two rows of high-pressure air nozzle assemblies includes a plurality of high-pressure air nozzle pieces 600 , and the plurality of high-pressure air nozzle pieces 600 are arranged in a direction perpendicular to the moving direction of the cloth.

[0072] You can refer to Figure 3 , the number of high-pressure air nozzle parts 600 can be set according to actual conditions, and the embodiment of the present invention does not specifically limit this. Among them, each row of high-pressure air nozzles can be 8 high-pressure air nozzle parts 600, that is, the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 have 8 high-pressure air nozzle parts 600 in each row. That is, a high-pressure air nozzle assembly and a second high-pressure air nozzle assembly 400 are arranged in the same row, and there are 18 high-pressure air nozzle parts 600. The high-pressure air nozzle parts 600 on the same side are relative to the jet airflow, but have a certain angle with the movement direction of the cloth. The purpose is to make the angle between the movement direction of the airflow after blowing on the surface of the cloth and the running direction of the cloth less than 90 degrees. You can refer to Figure 4The high-pressure air nozzle pieces 600 corresponding to the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are separated by the middle position. The high-pressure air nozzle piece 600 on one side blows toward one half of the cloth, and the high-pressure air nozzle piece 600 on the other side blows toward the other half of the cloth, so that the cloth can be quickly flattened. The high-pressure air nozzle pieces 600 corresponding to the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 use the cloth as a symmetry plane and symmetrically spray airflow. Because the wrinkle directions of the cloth may be different, only applying high-pressure airflow impact on one side of the cloth may not necessarily blow the cloth open 100%, so it is necessary to apply high-pressure airflow impact on both sides of the cloth at the same time. The blowing directions of the high-pressure air nozzle pieces 600 corresponding to the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are also symmetrical with the center line.

[0073] The shape of the high-pressure air nozzle 600 can be tested and an air nozzle shape that does not generate much noise can be selected, while maintaining the output of high-speed airflow and not generating much noise.

[0074] At the same time, in order to ensure that the two rows of high-pressure gas nozzle parts 600 have sufficient pressure, the first high-pressure gas nozzle assembly 300 and the second high-pressure gas nozzle assembly 400 may also include a pressure tank, which is connected to the high-pressure gas nozzle parts 600 in the two rows of high-pressure gas nozzle groups, and the volume of the pressure tank is greater than the total cross-sectional area of ​​the two rows of high-pressure gas nozzle groups.

[0075] Among them, two pressure tanks can be set, and one pressure tank is connected to a row of high-pressure air nozzle groups. The two rows of high-pressure air nozzle groups can be connected to the pressure tank through multiple air pipes. For example, 18 high-pressure air nozzle pieces 600 are symmetrical with the center, and the air pipes of the two high-pressure air nozzle pieces 600 at symmetrical positions on the left and right sides are connected together through an air pipe and connected to the pressure tank. In this way, there are 9 pressure air pipes in a pressure tank, and the air volume of each pressure air pipe can be adjusted by a valve. Therefore, it is best to connect a pressure gauge to each of the 9 pressure air pipes to facilitate the individual adjustment of the high-pressure air flow of each pressure air pipe. The 9 pressure air pipes coming out of the pressure tank are connected to the high-pressure air nozzle pieces 600 at symmetrical positions on the left and right, so that the air pressure in the left and right directions can be guaranteed to be the same, ensuring that the cloth will not be blown to one side.

[0076] In addition, for production safety, the pressure tank is provided with a safety relief valve, which can be opened to release pressure from the pressure tank when necessary.

[0077] The first high-pressure gas nozzle assembly 300 and the second high-pressure gas nozzle assembly 400 are both connected to the jet adjustment assembly, and the jet direction of the first high-pressure gas nozzle assembly 300 and the jet direction of the second high-pressure gas nozzle assembly 400 are adjusted by the jet adjustment assembly.

[0078] For example, the blowing directions of the nine high-pressure air nozzle pieces 600 in a row in the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 are the same. The nine high-pressure air nozzle pieces 600 in the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 can be linked together by the jet adjustment assembly to achieve synchronous adjustment. The angles between the high-pressure air nozzle pieces 600 in a row and the moving direction of the cloth are the same, and the angles are less than 90 degrees, and the angles between the 18 high-pressure air nozzle pieces 600 in the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 and the moving direction of the cloth can be synchronously adjusted.

[0079] Specifically, the jet adjustment assembly includes: an adjustment screw connected to the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400;

[0080] The operating part is connected to the adjusting screw and is used to rotate the adjusting screw to adjust the jetting direction of the first high-pressure gas nozzle assembly 300 and the jetting direction of the second high-pressure gas nozzle assembly 400 .

[0081] The first high-pressure gas nozzle assembly 300 and the second high-pressure gas nozzle assembly 400 can be connected to the adjustment screw respectively, and the angle can be adjusted accordingly when the adjustment screw is rotated. At least one section of the adjustment screw is provided with an operating part. The operator can rotate the adjustment screw through the operating part to adjust the jet direction of the first high-pressure gas nozzle assembly 300 and the jet direction of the second high-pressure gas nozzle assembly 400.

[0082] For example, the left and right air nozzle angles are adjusted in linkage to ensure that the position angles are symmetrical. When the high-pressure air nozzle parts 600 on one half of the same row are adjusted to change their angles in the horizontal direction, the symmetrical high-pressure air nozzle parts 600 will also make the same opposite angle adjustment. This row of high-pressure air nozzle parts 600 uses a screw to adjust the horizontal angle of the high-pressure air nozzle parts 600. The surface of the adjusting screw has precision threads that tightly engage with the threads on the high-pressure air nozzle parts 600. The angle of the high-pressure air nozzle parts 600 is adjusted by rotating the threads. The direction of the threads starts to reverse at the middle position of the screw, so that the angles of the high-pressure air nozzle parts 600 on the two halves of the same row can be adjusted in reverse. When the vertical angles of 18 air nozzles in one row are adjusted, the other row of high-pressure air nozzle parts 600 will also have the same angle adjustment on the symmetrical side. The vertical angle synchronization adjustment of these two rows of high-pressure air nozzle parts 600 can be achieved by fixing gears of the same diameter at both ends to engage with each other. In this way, the horizontal angles of 36 high-pressure air nozzle parts 600 in two rows can be adjusted synchronously, and the vertical angles can also be adjusted synchronously. After the angle of the high-pressure air nozzle 600 is accurately adjusted at the initial position, when the angle of the high-pressure air nozzle 600 is adjusted again later, a lot of time can be saved to ensure that the angles of the air nozzles on the left and right sides are consistent, thereby simplifying the operation difficulty.

[0083] In addition, the jet adjustment assembly also includes:

[0084] A locking member is connected to the adjusting screw rod and is used to limit the movement range of the adjusting screw rod.

[0085] The locking member is connected to the adjusting screw rod. After the adjusting screw rod reaches the corresponding position, the locking member can be used to limit the movement range of the adjusting screw rod, thereby fixing the position of the adjusting screw rod, and then fixing the angle between the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 and the fabric. The angle and position of the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 will not be offset due to the reaction of the high-pressure airflow.

[0086] The dust suction groove 500 can also be arranged at the upper roll end of the cloth inspection machine, and the dust suction groove 500 can be located on the side of the first roller 100 and the second roller 200 away from the first nozzle assembly or the second nozzle assembly. Figure 2 As shown, the dust suction groove 500 is located above the first roller 100 and the second roller 200 .

[0087] The dust suction groove 500 is an open structure, that is, it has at least one opening structure, wherein the opening of one of the opening structures is oriented toward the jet direction of the first high-pressure air nozzle assembly 300, and / or, toward the jet direction of the second high-pressure air nozzle assembly 400, so that when the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400 blow air to remove dust from the cloth, the dust can be blown into the dust suction groove 500 along the wind direction, and the dust is collected and centrally processed by the dust suction groove 500, thereby avoiding environmental pollution and protecting the respiratory health of the operator.

[0088] After determining the sizes of the first roller 100, the second roller 200, the first high-pressure air nozzle assembly 300, the second high-pressure air nozzle assembly 400, the jet adjustment assembly and the dust suction groove 500, a position can be found at one end of the upper roll of the cloth inspection machine, with sufficient space to install the first roller 100, the second roller 200, the first high-pressure air nozzle assembly 300, the second high-pressure air nozzle assembly 400 and the dust suction groove 500. The cloth with detection is in a vertical state to the ground, so that the first roller 100, the second roller 200, the first high-pressure air nozzle assembly 300, the second high-pressure air nozzle assembly 400 and the dust suction groove 500 can be respectively on both sides of the cloth, and the high-pressure airflow does not need to bear the gravity of the cloth itself, which can ensure that the high-pressure airflow on both sides of the cloth offsets the force on the cloth, and keeps the cloth between the first roller 100 and the second roller 200. Therefore, the first roller 100 and the second roller 200 will basically not come into contact with the cloth under normal working conditions, and are only used to limit the cloth to prevent the cloth from scratching the first high-pressure air nozzle assembly and the second high-pressure air nozzle assembly 400 and damaging the cloth surface.

[0089] In one embodiment of the present invention, the dust collecting slot 500 comprises:

[0090] An open slot body, wherein the open slot body is arranged at the upper roll end of the fabric inspection machine, and the opening of the open slot body faces the jet direction of the first high-pressure air nozzle assembly 300 and / or faces the jet direction of the second high-pressure air nozzle assembly 400;

[0091] The turbofan negative pressure chamber is connected to the open slot body and is arranged at one end of the open slot body away from the first roller shaft 100 and / or the second roller shaft 200.

[0092] The open slot body can be arranged at the upper roll end of the cloth inspection machine, and the opening of the open slot body faces the jet direction of the first high-pressure air nozzle assembly 300, and / or, faces the jet direction of the second high-pressure air nozzle assembly 400, that is, the open slot body of the dust suction slot 500 faces the direction of the high-speed airflow ejected by the first high-pressure air nozzle assembly 300 and the second high-pressure air nozzle assembly 400, and timely absorbs and discharges the dust and foreign matter blown away by the high-speed airflow. The open slot body is connected to the turbofan negative pressure bin. It is arranged at one end of the open slot body away from the first roller 100 and / or the second roller 200 to generate negative pressure so that the open slot body can absorb dust and foreign matter. The air outlet of the dust suction slot 500 is extended to the outside of the factory building or a separate room through a pipeline, and the air outlet is filtered by a cloth bag. In one example of the present invention, the cloth bag has a diameter of 30 cm and a length of 10 meters.

[0093] The turbofan negative pressure chamber can be composed of a brushless motor and a turbofan. The shape of the turbofan blades can be similar to the engine blade structure of an aircraft to obtain the maximum negative pressure. The brushless motor includes a rotor and a stator. Stator: It is wound with three-phase windings, which are symmetrically distributed and are usually made of magnetic conductive materials such as silicon steel sheets to improve the conduction efficiency of the magnetic field. Rotor: Permanent magnet, made of high-performance permanent magnetic materials such as neodymium iron boron.

[0094] The working principle of brushless motor is as follows:

[0095] When current is passed through the three-phase windings in a specific sequence, a rotating magnetic field is generated inside the stator.

[0096] The magnetic field generated by the permanent magnets interacts with the rotating magnetic field generated by the stator windings, causing the rotor to rotate due to torque.

[0097] Usually, position detection elements such as Hall sensors are used to detect the position information of the rotor, and this information is fed back to the driver in real time.

[0098] The driver energizes the stator windings in a specific order based on the rotor position information, thereby controlling the motor speed and torque.

[0099] In addition, the brushless motor in the turbofan negative pressure chamber of the dust suction tank 500 can also use a silent motor, and the filter bag at the air outlet is placed in a dedicated dust removal room to maintain ventilation and avoid the risk of explosion due to dust. The silent motor is mainly designed for the bearing: low-noise bearings are used to reduce friction and vibration, thereby reducing noise. Air gap optimization: By optimizing the air gap between the stator and the rotor, the interaction between electromagnetic force and mechanical force is reduced, thereby reducing noise. Casing sound insulation: The casing is made of sound insulation material to further isolate the spread of noise. Thereby, the noise generated by the cloth inspection machine during operation can be reduced.

[0100] The dust removal and flattening mechanism of the embodiment of the present invention can quickly flatten the surface of the cloth and remove dust on the surface of the cloth, thereby improving the detection efficiency and accuracy of the cloth inspection machine; and can reduce damage to the surface of the cloth; and can be compatible with higher cloth movement speeds, thereby facilitating improved detection efficiency.
