Cloth dust removing device

Abstract

The application discloses a cloth dust removal device, which comprises a film brush module and a dust collection module. The dust collection module is arranged on at least one side of the film brush module. The film brush module comprises a rotating shaft and at least one group of fan blade assemblies fixed to the rotating shaft. The dust collection module comprises a main dust collection cavity. The opening of the main dust collection cavity is in the centrifugal direction of the film brush module. When the rotating shaft rotates, the rotating shaft drives all the fan blade assemblies to rotate synchronously. All the fan blades directly contact with the cloth to sweep the dust on the cloth. At the same time, the strong airflow generated by the rotation of the fan blades blows away the dust swept from the surface of the cloth. At the same time, the dust generated by the film brush module is blown into the main dust collection cavity by the airflow. The dust floats in the main dust collection cavity and finally adheres to the side wall of the main dust collection cavity along with the airflow. Therefore, the dust can be collected only by the rotation of the film brush module, and a dust suction device is not needed, so that the dust removal efficiency is improved and the energy consumption is reduced.

Description

Technical Field

[0001] This invention relates to the field of fabric inspection technology, and in particular to a fabric dust removal device. Background Technology

[0002] Fabric inspection machines are specialized equipment used in the textile industry to inspect extra-large, double-width, and single-width fabrics such as cotton, wool, linen, silk, and synthetic fibers before shipment and in the garment industry before production. Their purpose is to inspect the appearance quality of the fabric and determine if it has any defects. While existing intelligent fabric inspection machines can identify defects through vision and algorithms, surface imperfections such as lint and dust on the fabric can cause false positives, thus limiting inspection efficiency.

[0003] Existing dust removal devices on fabric inspection machines, such as the patent with publication number CN217174127U, have cleaning plates on the fabric inspection machine. The fabric passes between metal part one and metal part two. The drive motor works, and the extension plate pushes the built-in strip, causing the two cleaning plates to squeeze and stretch the connecting spring, so that the two cleaning plates move back and forth, which can clean the dust on the fabric sandwiched in the middle.

[0004] Patent CN213638313U discloses a negative pressure electrostatic eliminator mechanism for dust removal in fabric rolling devices. The disclosed dust collection mechanism includes a suction fan and a dust collection box. A suction pipe is fixedly connected to the right side of the mechanism, and a first rotating shaft is fixedly connected to the outside of the suction pipe. The first rotating shaft is a hollow shaft, and a dust collection cylinder is fixedly connected to the outside of the first rotating shaft. A brush is installed on the surface of the dust collection cylinder, and several dust inlet holes are opened on the surface of the dust collection cylinder. The suction fan sucks out the lint and dust from the dust collection cylinder through the first rotating shaft. However, the dust removal device and dust collection module of such fabric inspection machines usually have independently set drive components, resulting in high energy consumption and poor dust removal effect.

[0090] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0091] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0092] This invention discloses a fabric dust removal device, applicable to various fabric inspection machines. (See attached image.) Figure 1 and 2 As shown, the above-mentioned fabric dust removal device includes a thin film brush module 1 and a dust collection module 2. The thin film brush module 1 is used to remove dust from the fabric, and the dust collection module 2 is used to collect the lint and dust removed by the dust collection module 2.

[0093] The thin-film brush module 1 includes a rotatably mounted rotating shaft 11 and at least one set of fan blade assemblies 12. Specifically, one end of the rotating shaft 11 is fixedly connected to a driven pulley, and the driving pulley is fixedly connected to a drive motor. The driving pulley transmits the torque of the drive motor to the driven pulley via a synchronous belt, causing the driven pulley to drive the rotating shaft 11 to rotate synchronously. Of course, the driving method of the rotating shaft 11 is not limited to this. All fan blade assemblies 12 are fixed to the rotating shaft 11, and all fan blade assemblies 12 are distributed along the axial direction of the rotating shaft 11.

[0094] As attached Figures 3 to 10 As shown, the dust collection module 2 is located on at least one side of the film brush module 1. The dust collection module 2 includes a main dust collection chamber 21, and the opening of the main dust collection chamber 21 is in the centrifugal direction of the film brush module 1.

[0095] When the rotating shaft 11 rotates, it drives all the fan blade assemblies 12 to rotate synchronously. All the fan blades 121 rotate and come into direct contact with the fabric, sweeping away the lint and dust on the fabric. At the same time, the rotation of the fan blades 121 generates a strong airflow, blowing away the lint and dust swept away from the fabric surface. Meanwhile, the lint and dust generated by the membrane brush module 1 are blown into the main dust collection chamber 21 by the airflow. The lint and dust float in the main dust collection chamber 21 and eventually adhere to the side wall of the main dust collection chamber 21 with the airflow. In this way, the lint and dust can be collected by only the rotation of the membrane brush module 1, without the need for a separate dust collection device, which can effectively improve the dust removal efficiency and reduce energy consumption.

[0096] Each fan blade assembly 12 includes several sets of fan blades 121, all of which are radially distributed. When the rotating shaft 11 rotates, it drives all the fan blade assemblies 12 to rotate synchronously. The rotation of all the fan blades 121 generates a strong airflow that blows away the dust and lint swept from the fabric surface. A flexible brush 122 is fixed to the end of each set of fan blades 121. The flexible brush 122 rotates synchronously with the fan blades 121, brushing away the dust and lint adhering to the fabric surface, breaking down the adhesion of the dust and lint, making it easier to blow away.

[0097] The flexible brush 122 is plate-shaped, made of a soft material, and has a large contact area with the fabric, making it easier to remove lint and dust. It also avoids damaging the fabric like a regular brush does, and prevents secondary pollution from shedding lint. The flexible brush 122 can be made of plastic or silicone, etc., without specific limitations. Of course, the type of flexible brush 122 can be changed depending on the fabric material; for example, a regular brush can be used without affecting the purpose of this invention. This invention optimizes the structure of the film brush module 1, enabling it to use both air blowing and brushing methods for dust removal, making it easier to completely remove lint and dust from the fabric and achieving better dust removal results.

[0098] Each fan blade assembly 12 includes at least one set of impellers 123. A fixing sleeve 124 is fixedly fitted around the impeller 123 at the first end, and a locking member 125 passes through the side wall of the fixing sleeve 124. When dust removal is required, the locking member 125 abuts against the rotating shaft 11 radially, and is in a locked state. The fan blade assembly 12 is locked and fixed to the rotating shaft 11, ensuring that all fan blade assemblies 12 rotate synchronously with the rotating shaft 11. When cleaning the membrane brush module 1 is required, the locking member 125 moves away from the rotating shaft 11, and is in an unlocked state. All impellers 123 are not fixed to the rotating shaft 11, and the fan blade assembly 12 can move freely along the axial direction of the rotating shaft 11, facilitating quick removal of the fan blade assembly 12 from the rotating shaft 11.

[0099] The fixing sleeve 124 is provided with several slots, and all the blade bases 126 on the impeller 123 at the first end are engaged with each slot to prevent the fixing sleeve 124 and the impeller 123 at the first end from rotating relative to each other in the circumferential direction. The impeller 123 and the fixing sleeve 124 can be detachably connected by fastening screws for easy assembly and disassembly.

[0100] The locking element 125 is specifically a spring plunger. The spring plunger engages with the threaded hole in the impeller 123, allowing for easier adjustment of the locking element 125's working state and making it more convenient to use. For details on the structure and working principle of the spring plunger, please refer to the spring plunger disclosed in patent publication number CN206017383U, which will not be elaborated here. Of course, the type of locking element 125 is not limited to this.

[0101] In addition to the blades 121 and impeller 123, each blade assembly 12 also includes several blade bases 126 and several flexible clamping plates 127. All blade bases 126 are radially distributed and fixed to the impeller 123, primarily serving a supporting function. All blade bases 126 can be welded evenly to the outer surface of the impeller 123. For each blade assembly 12, all blades 121 are fixed to all blade bases 126, and all flexible clamping plates 127 are fixed to all blades 121. A flexible brush 122 is fixed to the side of each flexible clamping plate 127 away from the blades 121. The flexible clamping plates 127 are made of a relatively soft material, providing elastic support for the flexible brushes 122, increasing the contact force of the brushes, making it easier for the brushes to clean dust and grime, and preventing the metal blades 121 from scratching the fabric.

[0102] In this specific embodiment, two sets of fan blade assemblies 12 are fixedly mounted on the rotating shaft 11. Each set of fan blade assemblies 12 includes three sets of impellers 123. Each set of impellers 123 has six sets of radially distributed blade bases 126. However, the blade bases 126 of the three sets of impellers 123 together hold one set of blades 121, that is, the six sets of blades 121 can rotate synchronously under the joint support of the three sets of impellers 123. Of course, the arrangement of impellers 123 and the number of fan blade assemblies 12 can be adaptively adjusted according to the rotational speed of the rotating shaft 11, and are not specifically limited here.

[0103] Each set of fan blade bases 126 includes two parallel base plates 1261, with each set of fan blades 121 sandwiched between the two base plates 1261. Each set of fan blades 121 includes two parallel fan blades 1211, with each set of flexible clamping plates 127 sandwiched between the two fan blades 1211. Each set of flexible clamping plates 127 includes two parallel flexible plates, with a flexible brush 122 sandwiched between the two flexible plates.

[0104] For each set of fan blades 12, a support sleeve 1262 is fixed between the two base plates 1261 to support each set of fan blades 121. It should be noted that the sum of the thicknesses of each set of fan blades 121, each set of flexible clamping plates 127, and the flexible brush 122 is less than the length of the support sleeve 1262, causing the flexible clamping plates 127 to be slightly pressed between the two fan blades 1211. This ensures that each set of fan blades 121 firmly clamps each set of flexible clamping plates 127, thereby ensuring that each set of flexible clamping plates 127 firmly clamps the flexible brush 122, making the flexible brush 122 more securely fixed. Furthermore, for each set of fan blades 12, each end of each set of fan blades 121 is provided with a limiting groove, which abuts against the support sleeve 1262 of the fan blade base 126 located at the end, thereby axially limiting the fan blades 121. Each set of fan blades 121 has a clearance groove in the middle, which can be L-shaped, to avoid the support sleeve 1262 of the fan blade base 126 located in the middle.

[0105] For each set of fan blades 12, at least one set of quick-release components 13 is provided between each set of fan blades 121 and each set of flexible clamps 127, which facilitates quick installation and removal of each set of flexible clamps 127 from each set of fan blades 121, and facilitates quick replacement of worn flexible brushes 122. All quick-release components 13 are evenly distributed along a line to ensure that each set of flexible clamps 127 and flexible brushes 122 are subjected to uniform force.

[0106] Each quick-release assembly 13 includes a connecting bolt 131, a positioning clamp 132, and a compression spring 133. For each fan blade assembly 12, the connecting bolt 131 passes through each fan blade 121 and each flexible clamping plate 127. The positioning clamp 132 is detachably fixed to the connecting bolt 131, that is, the positioning clamp 132 is threadedly engaged with the connecting bolt 131, which facilitates the installation and removal of the positioning clamp 132. One fan blade 1211 of each fan blade 121 and both flexible plates of each flexible clamping plate 127 are provided with through positioning holes 128, which are concave and convex with the positioning clamp 132.

[0107] A compression spring 133 is sleeved on the connecting bolt 131. The compression spring 133 and the positioning clamp 132 are located on both sides of each set of fan blades 121, so that the compression spring 133 can press each set of fan blades 121 and each set of flexible clamps 127 with elastic force, so that each set of fan blades 121 and each set of flexible clamps 127 of each set of fan blade assembly 12 is reliably fixed. The compression spring 133 can be a common cylindrical spring, but is not limited to it.

[0108] Both the positioning through hole 128 and the positioning clamp 132 can be oblong, or they can be rectangular or triangular, etc., without any specific limitation.

[0109] When the flexible brush 122 needs to be replaced, first rotate the connecting bolt 131. The positioning clamp 132 rotates 90 degrees synchronously with the connecting bolt 131 until the positioning clamp 132 is coaxial with the positioning through hole 128. The compression spring 133 returns to its elastic deformation and pushes the connecting bolt 131. The connecting bolt 131 drives the positioning clamp 132 to move. The positioning clamp 132 drills into the positioning through hole 128. At this time, one of the fan blades 1211 can be removed first, and then the flexible clamp 127 can be removed. The flexible brush 122 can be quickly disassembled without the aid of disassembly and assembly tools.

[0110] When the flexible brush 122 is replaced, first press the connecting bolt 131, and the positioning clamp 132 will drill out from the positioning through hole 128, and the compression spring 133 will be compressed; then rotate the connecting bolt 131, and the positioning clamp 132 will be staggered from the positioning through hole 128. The positioning clamp 132 and the positioning through hole 128 can be set at a 90-degree angle at this time. The positioning clamp 132 and the compression spring 133 will abut against the two sides of the fan blade 121 respectively. Each set of fan blades 121 can reliably clamp the flexible clamp plate 127 and the flexible brush 122 during the dust removal process.

[0111] Each set of fan blades 121 includes two parallel fan blades 1211. Each set of fan blades 121 is provided with at least one positioning pin 14. All positioning pins 14 are evenly distributed along a line to define the position of each set of flexible clamping plates 127 and flexible brushes 122, ensuring that the position of each set of flexible clamping plates 127 and flexible brushes 122 remains unchanged during dust removal. One end of each positioning pin 14 is detachably fixed to one of the fan blades 1211, and the other end of the positioning pin 14 passes through the other fan blade 1211. Specifically, the fan blade 1211 that abuts against the compression spring 133 is provided with a fixing hole, and the positioning pin 14 is threadedly connected to the fixing hole. The other end of the positioning pin 14 is sequentially connected to one of the flexible plates of the flexible clamping plate 127, the flexible brush 122, the other flexible plate of the flexible clamping plate 127, and the other fan blade 1211. Of course, the installation method of the positioning pin 14 is not limited to this.

[0112] The rotating shaft 11 has bearing housings 15 at both ends, which are fixedly installed. A slewing bearing is provided between the rotating shaft 11 and the bearing housings 15 to support the rotation of the rotating shaft 11 relative to the bearing housings 15. The inner and outer rings of the slewing bearing are interference-fitted to the rotating shaft 11 and the bearing housings 15, respectively. The slewing bearing can be a deep groove ball bearing, but is not limited to this.

[0113] As attached Figures 11 to 17As shown, the dust collection module 2 includes a guide plate 211, a first lower dust collection plate 212, and a first side dust collection plate 213. The guide plate 211 and the first lower dust collection plate 212 are arranged vertically opposite each other, with the guide plate 211 positioned above the first lower dust collection plate 212, but its height is between the first side dust collection plate 213 and the top baffle 23. The film brush module 11 is rotatably mounted. During rotation, the film brush module 11 generates airflow carrying dust particles, which the guide plate 211 guides. The first side dust collection plate 213 connects the guide plate 211 and the first lower dust collection plate 212, with the first lower dust collection plate 212 located below the first side dust collection plate 213. Both the first lower dust collection plate 212 and the first side dust collection plate 213 are perforated mesh screens used to collect dust particles from the airflow, allowing the dust to accumulate through adhesion.

[0114] The guide plate 211, the first side dust collection plate 213, and the first lower dust collection plate 212 are arranged to form the main dust collection chamber 21, with the opening of the main dust collection chamber 21 facing the thin film brush module 11. It should be noted that the guide plate 211 is tangent to the rotation direction of the thin film brush module 11, so that the opening of the main dust collection chamber 21 is in the centrifugal direction of the thin film brush module 11, ensuring that the airflow flows into the main dust collection chamber 21 to the maximum extent, thus achieving efficient dust collection.

[0115] When the thin film brush module 11 rotates, the airflow generated by the rotation of the thin film brush module 11 is intercepted by the guide plate 211. Under the guidance of the guide plate 211, the dust generated by the thin film brush module 11 is blown into the main dust collection chamber 21 by the airflow. The dust floats in the main dust collection chamber 21 and eventually adheres to the first lower dust collection plate 212 and the first side dust collection plate 213 with the airflow. In this way, the dust can be collected by relying only on the airflow generated by the rotation of the thin film brush module 11, without the need for a separate dust collection device, effectively reducing energy consumption and achieving energy saving.

[0116] In addition, a main baffle plate 214 is fixed at each end of the main dust collection chamber 21 to seal both ends of the main dust collection chamber 21 and prevent dust from drifting into the working environment. The main baffle plate 214 can be fixed with fastening screws. The main baffle plate 214 can be equipped with a viewing window to facilitate timely observation of the amount of dust collected in the main dust collection chamber 21 and to facilitate timely cleaning.

[0117] The aforementioned dust collection module 2 also includes a fixedly installed lower support base 215, which supports the first lower dust collection plate 212. Specifically, the lower support base 215 can be fixed to the fixing frame 24. The lower support base 215 can be a split structure, including two L-shaped supports respectively located at both ends of the first lower dust collection plate 212. The two L-shaped supports can be fixed to the frame by welding. Crucially, the first lower dust collection plate 212 rests on the lower support base 215, meaning the first lower dust collection plate 212 falls onto the lower support base 215 by gravity. The lower support base 215 limits the position of the first lower dust collection plate 212, thus facilitating quick and easy disassembly and assembly of the first lower dust collection plate 212 during dust removal. Of course, the installation method of the first lower dust collection plate 212 is not limited to this.

[0118] The first lower dust collection plate 212 extends upward from the lower support base 215 to the film brush module 11, that is, the first lower dust collection plate 212 is set at an angle, which can increase the dust collection area and improve the dust collection efficiency. The tilt angle of the first lower dust collection plate 212 can be adapted to the specifications of the film brush module 11, and is not specifically limited here.

[0119] The first lower dust collection plate 212 is a bent plate. An integrally formed downward-bent support flange 2122 is provided on the side of the first lower dust collection plate 212 closest to the film brush module 11. A flexible scraper 216 is fixedly mounted on the support flange 2122. The flexible scraper 216 abuts against the flexible brush 122 of the film brush module 11. The flexible scraper 216 is used to scrape off the dust adhering to the flexible brush 122, preventing secondary contamination during dust removal. Additionally, the flexible scraper 216 prevents direct contact between the first lower dust collection plate 212 and the flexible brush 122, avoiding scratches. The bending angle of the support flange 2122 can be adaptively set according to the radial length of the flexible brush 122, and is not specifically limited here. The flexible scraper 216 is made of a flexible material, specifically a plastic plate or a silicone plate, but is not limited to these.

[0120] At least one of the first lower dust collection plate 212 and the first side dust collection plate 213 is in a continuous zigzag shape to increase the adhesion area of ​​the dust and improve dust collection efficiency. Preferably, the first lower dust collection plate 212 is plate-shaped and the first side dust collection plate 213 is in a continuous zigzag shape, but it is not limited thereto.

[0121] The dust collection module 2 also includes a fixed upper support base 217 for supporting the guide plate 211. The upper support base 217 can be welded and fixed to the fixing frame 24. The fixing frame 24 can be C-shaped and is used to provide support for the various components of the dust collection module 2. The guide plate 211 is horizontally fixed to the upper support base 217, ensuring reliable fixation of the guide plate 211 and optimizing its flow guiding effect. Of course, the fixing method of the guide plate 211 is not limited to this.

[0122] The aforementioned dust collection module 2 also includes a top side baffle 23, a second lower dust collection plate 221, and a second side dust collection plate 222. The top side baffle 23 is fixedly installed and located above the guide plate 211, mainly serving a protective function to prevent dust from flying out and affecting the working environment. A first side protective plate 25 is fixedly connected between the top side baffle 23 and the first side dust collection plate 213, and a second side protective plate 26 is fixedly installed between the top side baffle 23 and the second side dust collection plate 222. Both the first side protective plate 25 and the second side protective plate 26 are L-shaped, and their functions are the same as those of the top side baffle 23, both used to isolate the external working environment and achieve a protective purpose. The second lower dust collection plate 221 is opposite to the top side baffle 23, and the bottom edges of the first lower dust collection plate 212 and the second lower dust collection plate 221 are at the same height. The second side dust collection plate 222 is opposite to the first side dust collection plate 213, and the two can be symmetrically distributed on the left and right sides of the film brush module 11. The second side dust collection plate 222 is connected between the top side baffle 23 and the second lower dust collection plate 221. The top side baffle 23, the second side dust collection plate 222 and the second lower dust collection plate 221 are arranged to form a secondary dust collection chamber 22. The secondary dust collection chamber 22 and the main dust collection chamber 21 are located on both sides of the film brush module 11, and the opening of the secondary dust collection chamber 22 also faces the film brush module 11.

[0123] When the thin film brush module 11 rotates, part of the airflow generated by the rotation of the thin film brush module 11 flows into the main dust collection chamber 21, and another part flows into the secondary dust collection chamber 22. The airflow continues to blow the dust that overflows from the main dust collection chamber 21 into the secondary dust collection chamber 22. The dust floats in the secondary dust collection chamber 22 and finally adheres to the second lower dust collection plate 221 and the second side dust collection plate 222 with the airflow, so as to fully collect the dust and achieve a better dust collection effect.

[0124] A secondary baffle plate 223 is fixedly installed at each end of the secondary dust collection chamber 22 to seal both ends of the secondary dust collection chamber 22 and prevent dust from drifting into the working environment. The secondary baffle plate 223 can also be fixed to the frame 4 with fastening screws. The secondary baffle plate 223 can also be provided with a viewing window to facilitate timely observation of the amount of dust collected in the secondary dust collection chamber 22 and facilitate timely cleaning.

[0125] Additionally, each end of the film brush module 11 is also fixed with an outer sealing plate 16 to enclose the film brush module 11 and the dust collection module 2, isolating them from the external environment and preventing dust from flying into the working environment. The outer sealing plates 16 can be fixed to the two opposite sides of the frame 4 with fastening screws.

[0126] At least one of the second lower dust collection plate 221 and the second side dust collection plate 222 is in a continuous zigzag shape to further increase the adhesion area of ​​the ash, thereby further improving the dust collection efficiency. Preferably, the second lower dust collection plate 221 is plate-shaped, and the second side dust collection plate 222 is in a connected zigzag shape.

[0127] The second lower dust collection plate 221 extends upward from the bottom of the second side dust collection plate 222 to the film brush module 11. That is, the second lower dust collection plate 221 is also inclined, which can increase the dust collection area and improve the dust collection efficiency.

[0128] The first dust collection plate 213 and the second dust collection plate 222 have the same structure, as shown in the attached figure. Figures 18 to 21 As shown, the first side dust collection plate 213 includes a dust collection frame 2131, a limiting frame 2134, and a dust collection net 2135. The dust collection frame 2131 mainly serves a supporting function, supporting the limiting frame 2134 and the dust collection net 2135. The limiting frame 2134 is used to change the folding shape of the dust collection net 2135 laid on the dust collection frame 2131, thereby limiting the dust collection net 2135. The dust collection net 2135 is located between the dust collection frame 2131 and the limiting frame 2134. The dust collection net 2135 is made of flexible material and can be flexibly bent to collect floating dust.

[0129] The dust collection rack 2131 has at least one dust collection rod 2132, and the limiting rack 2134 has at least one limiting rod 2139. All the dust collection rods 2132 and all the limiting rods 2139 are arranged in an alternating manner, so that the dust collection net 2135 is in a continuous zigzag shape. In this way, the dust collection area of ​​the first side dust collection plate 213 reaches the maximum and the dust collection efficiency is high.

[0130] The limiting bracket 2134 is detachable. When cleaning the first side dust collection plate 213 is required, the limiting bracket 2134 is removed, releasing the limiting bracket from restricting the dust collection net 2135. The dust collection net 2135 can then be pulled off the dust collection frame 2131, fully unfolding and allowing for cleaning with an air gun. This invention optimizes the structure of the first side dust collection plate 213, making the dust collection net 2135 easy to remove and assemble. This invention improves both the dust collection efficiency and ease of assembly / disassembly of the first side dust collection plate 213 by optimizing its structure. The structure and disassembly method of the second side dust collection plate 222 are detailed in the same way as the first side dust collection plate 213 and will not be described further here.

[0131] The dust collection rack 2131 includes two opposing left and right support plates, with all dust collection rods 2132 fixed between them. Any two adjacent dust collection rods 2132 are equidistant. Both the left and right support plates have at least one locking groove 2133. All locking grooves 2133 on the left support plate and all locking grooves 2133 on the right support plate are coaxially connected, and all limiting rods 2139 are correspondingly locked into the locking grooves 2133. When all limiting rods 2139 are correspondingly locked into the locking grooves 2133, a limiting frame 2134 is fixed to the dust collection rack 2131, restricting the dust collection net 2135 and changing its folding shape. When all limiting rods 2139 are pulled out laterally from the locking grooves 2133, the limiting frame 2134 releases the restriction on the dust collection net 2135. Of course, the installation method of the limit bracket 2134 is not limited to this.

[0132] Each locking slot 2133 is a U-shaped slot, with its center line perpendicular to the dust collection rod 2132, facilitating quick and easy removal of the limiting bracket 2134. Alternatively, the center line of the locking slot 2133 can intersect the dust collection rod 2132 at an angle, meaning the opening of the locking slot 2133 is higher than its bottom, which can limit the position of the limiting rod 2139 to a certain extent, thereby preventing the limiting bracket 2134 from accidentally coming loose.

[0133] The left support plate has at least one left mounting hole, and the right support plate has at least one right mounting hole. All left mounting holes and all right mounting holes are coaxially connected and correspond one-to-one. The two ends of each dust collection rod 2132 pass through any set of interconnected left and right mounting holes. A left stop and a right stop are fixed at both ends of the dust collection rod 2132, respectively. The left stop abuts against the edge of the left mounting hole, and the right stop abuts against the edge of the right mounting hole, to axially restrict the movement of the dust collection rod 2132.

[0134] Both the left and right stop components are integral stop flanges fixed at both ends of the dust collection rod 2132. The stop flanges can be formed by stamping from both ends of the dust collection rod 2132. Of course, the stop flanges can also be replaced by stop nuts, which can both axially limit the dust collection rod 2132 and facilitate the disassembly and assembly of the dust collection rod 2132.

[0135] The limiting frame 2134 includes a left limiting plate and a right limiting plate arranged opposite each other, and all limiting rods 2139 are fixed between the left and right limiting plates, with any two adjacent limiting rods 2139 being equally spaced. Of course, the structure of the limiting frame 2134 is not limited to this. For details on the installation method of each limiting rod 2139, please refer to the dust collection rod 2132 described above, which will not be elaborated upon here.

[0136] The dust collection net 2135 has an upper fixing rod 2136 and a lower fixing rod 2137 fixed at both ends. The upper fixing rod 2136 and lower fixing rod 2137 are detachably secured to the upper and lower ends of the dust collection frame 2131, thus fixing both ends of the dust collection net 2135 and allowing for easy and quick removal of the lower fixing rod 2137, facilitating the flattening of the dust collection net 2135. The dust collection frame 2131 has fixing grooves 2138 at both ends for fixing the upper fixing rod 2136 and lower fixing rod 2137. The position of the fixing grooves 2138 can be adapted to the length of the dust collection net 2135 and is not specifically limited here. Of course, at least one fixing groove 2138 can be provided at each end of the dust collection frame 2131 to flexibly adjust the fixing positions of the upper fixing rod 2136 and lower fixing rod 2137 to accommodate dust collection nets 2135 of different lengths. The fixing groove 2138 can be a U-shaped groove or an L-shaped groove. In addition to having a snap-fit ​​function, the L-shaped groove can also prevent the upper fixing rod 2136 or the lower fixing rod 2137 from disengaging from the fixing groove 2138.

[0137] Both the upper fixing rod 2136 and the lower fixing rod 2137 are cylindrical. Both ends of the upper fixing rod 2136 and the lower fixing rod 2137 can be fitted with elastic sleeves, specifically rubber sleeves, allowing both the upper fixing rod 2136 and the lower fixing rod 2137 to be reliably fixed within the fixing groove 2138 by the elastic force of the elastic sleeves. Both the upper fixing rod 2136 and the lower fixing rod 2137 are separate structures with identical structures, facilitating the disassembly and assembly of the dust collection screen 2135. The upper fixing rod 2136 includes an upper semicircular plate, a lower semicircular plate, and at least one fastening screw fixed between the upper and lower semicircular plates. The upper and lower semicircular plates are parallel, with their planes facing each other. The dust collection screen 2135 is fixed between the upper and lower semicircular plates. Of course, the structure of the upper fixing rod 2136 is not limited to this.

[0138] A limiting pin is detachably provided between the dust collection rack 2131 and the limiting rack 2134. The limiting pin passes through the dust collection rack 2131 and the limiting rack 2134. Specifically, it can be located between the left support plate and the left limiting plate, and between the right support plate and the right limiting plate. It is used to limit the position of the limiting rack 2134 so that the limiting rack 2134 is reliably fixed to the dust collection rack 2131.

[0139] The fabric guide module 3 is located below the film brush module 1, allowing the tensioned fabric to pass through the film brush module 1. The film brush module 1 removes dust from the fabric during the inspection process. (See attached image) Figures 22 to 25As shown, the fabric guiding module 3 includes a movable fabric guiding roller 31, a lifting seat 32, a lifting drive component 33, a fabric detection component, and a controller. The movable fabric guiding roller 31 is located below the film brush module 1. The outer surface of the movable fabric guiding roller 31 is cylindrical. During normal fabric inspection, fabric is wrapped around the movable fabric guiding roller 31. The movable fabric guiding roller 31 is used to guide the fabric released by the unwinding device 8, so that the fabric remains taut during the fabric inspection process and passes through the film brush module 1 in a taut state.

[0140] The lifting seat 32 is slidably mounted and fixedly connected to the movable guide roller 31, and is used to drive the movable guide roller 31 to move up and down in the vertical direction to approach or move away from the film brush module 1. Specifically, each end of the movable guide roller 31 is provided with a lifting seat 32, and the two sets of lifting seats 32 move up and down synchronously to ensure that the movable guide roller 31 moves up and down smoothly and to avoid the fabric tilting due to the tilting of the movable guide roller 31.

[0141] The lifting drive component 33 is fixedly installed, with its lifting end connected to the lifting seat 32, and is used to drive the lifting seat 32 to rise and fall. Specifically, the lifting drive component 33 can be a cylinder, with its cylinder barrel fixed to the frame 4 and its piston rod fixedly connected to the lifting seat 32. Of course, it can also be a hydraulic cylinder or a linear motor, etc., without specific limitations.

[0142] The fabric detection component is used to detect whether there is fabric wrapped around the movable guide roller 31. The fabric detection component can be an infrared sensor or a pressure sensor, etc., and its type is not specifically limited here. The controller is connected to both the fabric detection component and the lifting drive component 33.

[0143] When the fabric detection component detects that no fabric is wrapped around the movable guide roller 31, it sends a no-fabric signal to the controller. The controller receives the signal and sends a signal to the lifting drive component 33. The lifting drive component 33 retracts, and the lifting drive component 33 drives the lifting seat 32 to move downward. The lifting seat 32 drives the movable guide roller 31 to move away from the film brush module 1. The distance between the movable guide roller 31 and the film brush module 1 automatically increases, increasing the fabric threading operation space and making fabric threading more convenient.

[0144] The above-mentioned guide fabric module 3 also includes a shock-absorbing support 34 disposed between the lifting seat 32 and the movable guide fabric roller 31. The shock-absorbing support 34 is used to absorb the impact vibration generated during the lifting and lowering of the movable guide fabric roller 31, so that the movable guide fabric roller 31 can lift and lower stably and avoid the movable guide fabric roller 31 from vibrating violently and damaging the fabric being wound.

[0145] The shock-absorbing support 34 includes a movable connecting plate 341, a fixed connecting plate 342, at least one sliding guide rod 343, and at least one shock-absorbing elastic element 344. The movable connecting plate 341 is fixedly connected to the lifting seat 32 and rises and falls synchronously with the lifting seat 32. The movable connecting plate 341 may be L-shaped. A fixed bushing 301 is sleeved at the end of the movable guide roller 31, and the fixed connecting plate 342 is fixedly connected to the fixed bushing 301. The movable guide roller 31 may also be L-shaped. All sliding guide rods 343 can slide through the movable connecting plate 341 and are fixedly connected to the fixed connecting plate 342, used to guide the movable connecting plate 341 to slide linearly relative to the fixed connecting plate 342. Correspondingly, the movable connecting plate 341 is provided with at least one guide through hole, and all sliding guide rods 343 pass through all guide through holes one by one, with each sliding guide rod 343 slidably engaged with each guide through hole. Two sliding guide rods 343 can be provided, but the number of sliding guide rods 343 is not limited to this.

[0146] All damping elastic elements 344 are correspondingly fitted onto all sliding guide rods 343, with each end of the damping elastic element 344 abutting against the movable connecting plate 341 and the fixed connecting plate 342, respectively. Each damping elastic element 344 can be a common cylindrical spring, but is not limited to this. When the movable connecting plate 341 moves upward relative to the fixed connecting plate 342, all damping elastic elements 344 compress and store energy. When the lifting drive component 33 retracts, all damping elastic elements 344 restore their elastic deformation, and all damping elastic elements 344 push the lifting seat 32 downward through the movable connecting plate 341.

[0147] The damping support 34 also includes a limiting stop rod 345 fixed to the movable connecting plate 341. When the movable connecting plate 341 moves upward to its limit position with the lifting seat 32, the limiting stop rod 345 abuts against the fixed connecting plate 342, restricting the movable connecting plate 341 from moving further upward and preventing excessive movement of the movable connecting plate 341. The limiting stop rod 345 can specifically be a limiting bolt fixed to the movable connecting plate 341, but is not limited to this. Of course, the structure of the damping support 34 is not limited to this either.

[0148] The aforementioned fabric guiding module 3 also includes a fixed fabric guiding roller 35 parallel to the movable fabric guiding roller 31. The fixed fabric guiding roller 35 and the movable fabric guiding roller 31 work together to tension the fabric. The number of fixed and movable fabric guiding rollers 35 can be adjusted according to the fabric length and material, and is not specifically limited here. A shock-absorbing support 34 is provided between the fixed fabric guiding roller 35 and the frame 4 to absorb impact vibrations between them. The structure and working principle of the shock-absorbing support 34 between the fixed fabric guiding roller 35 and the frame 4 can be referred to the above description. Both the movable and fixed fabric guiding rollers 31 and 35 can be replaced by a smooth-surfaced fabric guiding plate without affecting the purpose of this invention.

[0149] The lifting platform 32 and the frame 4 are provided with a cooperating guide rail 36 and guide groove for guiding the lifting platform 32 to move linearly relative to the frame 4. The guide rail 36 is specifically a dovetail-shaped rail fixed to the inside of the frame 4, and the guide groove is specifically a dovetail-shaped groove located on the back of the lifting platform 32. Of course, the types of guide rail 36 and guide groove are not limited to these.

[0150] The aforementioned fabric guiding module 3 also includes a rotatably mounted pressure roller 37, which is used to press the fabric below by gravity, thus tensioning the fabric. The pressure roller 37 is rotatably mounted and parallel to the movable fabric guiding roller 31. The aforementioned fabric guiding module 3 also includes at least one swing arm 38 fixedly connected to the pressure roller 37. The ends of all swing arms 38 away from the pressure roller 37 are rotatably mounted on the frame 4, so that all swing arms 38 are used to support the pressure roller 37 to swing synchronously relative to the frame 4. The length and swing angle of the swing arms 38 can be adapted according to the installation space, and are not specifically limited here.

[0151] Each swing arm 38 is equipped with a counterweight assembly 39, which is used to adjust the swing angle of the swing arm 38, thereby adjusting the downward pressure of the pressure roller 37. Each counterweight assembly 39 includes a counterweight block 391, a sliding seat 392, a guide seat 393, and a sliding drive component 394. The sliding seat 392 is fixedly connected to the counterweight block 391, and the guide seat 393 is slidably engaged with the sliding seat 392. The guide seat 393 is provided with a linear slide rail, and the sliding seat 392 is provided with a linear slide groove. The linear slide rail and the linear slide groove cooperate to guide the sliding seat 392 to slide linearly relative to the guide seat 393. The sliding drive component 394 is fixedly mounted on the guide seat 393 and fixedly connected to the sliding seat 392. It is used to drive the sliding seat 392 to slide relative to the guide seat 393, thereby adjusting the position of the counterweight block 391 on the guide seat 393 through the sliding seat 392, so that the downward pressure of the pressure roller 37 on the fabric is appropriate, which can both tension the fabric and prevent damage to the fabric. The sliding drive component 394 can be a cylinder, but is not limited to that.

[0152] The aforementioned fabric guiding module 3 also includes a pressure detection element for detecting the pressure of the pressure roller 37. The pressure detection element and the sliding drive element 394 are respectively connected to the controller. Specifically, the pressure detection element can be a pressure sensor. When the pressure detection element detects that the downward pressure of the pressure roller 37 pressing against the fabric exceeds the preset pressure range, the pressure detection element sends a signal to the controller. The controller receives the signal and then sends a signal to the sliding drive element 394. The sliding drive element 394 adjusts the position of the counterweight 391 by extending and retracting, and adjusts the swing angle of the swing arm 38 to automatically adjust the downward pressure of the pressure roller 37 until the downward pressure of the pressure roller 37 is within the preset pressure range. This achieves automatic adjustment of the downward pressure of the pressure roller 37, with a high degree of automation and more convenient operation.

[0153] The aforementioned fabric dust removal device also includes a frame, a top cover plate 5, at least one safety bar 6, and a position detection component 7. The top cover plate 5 is rotatably mounted on the top of the frame. All safety bars 6 are rotatably mounted on the frame and are located in the feed channel of the film brush module 1. When the safety bar 6 is rotated upward to the open position, the fabric can enter the feed channel. The position detection component 7 is used to detect the position of the top cover plate 5 and all safety bars 6. Specifically, it can be a limit switch, but is not limited to this.

[0154] Before inserting the fabric, raise any one of the safety bars 6. When the position detection unit 7 detects that the safety bar 6 has been raised to the open position, the position detection unit 7 sends a signal to the controller. The controller receives the signal and sends a signal to control the power supply to cut off the power, preventing the film brush module 11 from accidentally starting and injuring the operator. In addition, during maintenance, when the upper cover 5 is flipped up to the open position, the controller can also control the power supply to cut off the power according to the signal fed back by the detection unit, preventing the machine from accidentally starting during maintenance.

[0155] The working principle of the fabric dust removal device provided by this invention is as follows:

[0156] Before inserting the fabric: First, lift any one of the safety bars 6. When the position detection element 7 detects that the safety bar 6 has been lifted to the open position, the position detection element 7 sends a signal to the controller. The controller receives the signal and sends a signal to control the power supply device to cut off the power.

[0157] Fabric threading action: When the fabric detection unit detects that no fabric is wrapped around the movable guide roller 31, the fabric detection unit sends a no-fabric signal to the controller. The controller receives the signal and sends a signal to the lifting drive 33. The lifting drive 33 retracts and drives the lifting seat 32 to move down. The lifting seat 32 drives the movable guide roller 31 to move away from the film brush module 1. The distance between the movable guide roller 31 and the film brush module 1 automatically increases, increasing the fabric threading operation space, and the fabric passes through the movable guide roller 31.

[0158] Dust removal action: When the rotating shaft 11 rotates, the rotating shaft 11 drives all the fan blade assemblies 12 to rotate synchronously. All the fan blades 121 rotate to form a strong airflow, blowing away the dust swept from the fabric surface. At the same time, the flexible brush 122 at the end of each fan blade 121 rotates synchronously with the fan blade 121. The flexible brush 122 brushes the dust attached to the fabric surface, breaking the adhesion of the dust and making it easier to blow away.

[0159] Dust collection action: When the thin film brush module 11 rotates, part of the airflow generated by the rotation of the thin film brush module 11 is intercepted by the guide plate 211. Under the guidance of the guide plate 211, the dust generated by the thin film brush module 11 is blown into the main dust collection chamber 21 by the airflow. The dust floats in the main dust collection chamber 21 and eventually adheres to the first lower dust collection plate 212 and the first side dust collection plate 213 with the airflow. At the same time, part of the airflow generated by the rotation of the thin film brush module 11 flows into the secondary dust collection chamber 22. The airflow continues to blow the dust that overflows from the main dust collection chamber 21 into the secondary dust collection chamber 22. The dust floats in the secondary dust collection chamber 22 and eventually adheres to the second lower dust collection plate 221 and the second side dust collection plate 222 with the airflow, thus collecting the dust.

[0160] Cleaning dust: Remove the limiting frame 2134. The limiting frame 2134 releases the restriction on the dust collection net 2135, so the dust collection net 2135 can be pulled off from the dust collection frame 2131. The dust collection net 2135 is fully flattened and opened, and the dust collection net 2135 can be cleaned with an air gun to clean the dust, thereby cleaning the first side dust collection plate 213 and the second side dust collection plate 222.

[0161] Replacing the flexible brush: When it is necessary to replace the flexible brush 122, first rotate the connecting bolt 131. The positioning clamp 132 rotates 90 degrees synchronously with the connecting bolt 131 until the positioning clamp 132 is coaxial with the positioning through hole 128. The compression spring 133 returns to its elastic deformation and pushes the connecting bolt 131. The connecting bolt 131 drives the positioning clamp 132 to move. The positioning clamp 132 drills into the positioning through hole 128. At this time, one of the fan blades 1211 can be removed first, and then the flexible clamp 127 can be removed. The flexible brush 122 can be quickly disassembled without the aid of disassembly and assembly tools. When the flexible brush 122 is replaced, first press the connecting bolt 131, and the positioning clamp 132 will drill out from the positioning through hole 128, and the compression spring 133 will be compressed; then rotate the connecting bolt 131, and the positioning clamp 132 will be staggered from the positioning through hole 128. The positioning clamp 132 and the positioning through hole 128 can be set at a 90-degree angle at this time. The positioning clamp 132 and the compression spring 133 will abut against the two sides of the fan blade 121 respectively. Each set of fan blades 121 can reliably clamp the flexible clamp plate 127 and the flexible brush 122 during the dust removal process.
