Description

Technical Field

[0001] The invention relates to the technical field of cloth processing, and in particular to a polyester cloth production coating device. Background Art

[0002] Polyester is a common polyester fiber. Due to its fineness, high softness, and good air permeability, it is widely used in clothing, home textiles and other fields. However, in some special environments, such as sunlight exposure, humidity, etc., the surface of polyester fiber is easily damaged, affecting product performance and appearance. Therefore, polyester surface coating technology came into being. Polyester surface coating is a method of modifying the surface of polyester fiber through coating technology. Common coating materials include polyurethane, fluorocarbon, acrylic, etc., which can coat and modify the surface of polyester fiber to achieve sun protection, waterproof, antibacterial and other effects. Polyester fabric coating is usually achieved using a coating device.

[0003] In the patent with the authorization announcement number CN217491448U, a composite device for gluing fabric is disclosed, which includes a back plate, an unwinding mechanism, a gluing mechanism and a rewinding mechanism; the unwinding mechanism is arranged on one side of the back plate; the gluing mechanism includes a connecting assembly, a material storage box and a gluing roller, the material storage box is arranged on the side of the connecting assembly away from the back plate, the gluing roller is arranged at the discharge port at the bottom of the material storage box, the gluing roller is rotatably connected to the connecting assembly, and the side of the connecting assembly close to the back plate is connected to the back plate; the rewinding mechanism includes a pressing roller and a supporting roller, and both the pressing roller and the supporting roller are rotatably connected to the back plate. When the device is working, the paint in the material storage box flows to the gluing roller through the discharge port, and the gluing roller rotates under the drive of the fabric and applies the paint on the fabric.

[0004] However, due to the poor fluidity and strong adhesion of the paint, the paint on the inner wall of the storage box is prone to drying up. The dried paint falls to the bottom of the storage box and flows into the discharge port along with the flowing paint, which affects the distance between the discharge port and the glue roller, causing uneven thickness of the paint on the glue roller, and then uneven thickness of the coating applied to the fabric, affecting the molding quality of the fabric. Moreover, if this continues for a long time, the discharge port and the glue roller will be blocked until the paint cannot flow out, causing the coating of the fabric to stop. Summary of the invention

[0005] The invention provides a polyester cloth production coating device, aiming to solve the technical problem in the related art that the coating thickness of the cloth is uneven, which affects the molding quality of the cloth.

[0006] The polyester cloth production coating device of the present invention comprises a cloth conveyor, a material storage tank for storing coating arranged above the cloth conveyor, a debris removal conveyor arranged in the material storage tank, a scraper assembly and a debris storage bent plate;

[0007] The bottom of the material storage tank is provided with a discharge port for the coating to flow out and be coated on the surface of the cloth; the material storage tank comprises a front inner wall and a rear inner wall arranged in sequence along the conveying direction of the cloth, and two side inner walls arranged in sequence along the width direction of the cloth and connecting the front inner wall and the rear inner wall; the front inner wall and the rear inner wall both comprise a concave arc surface;

[0008] The impurity removal conveyor comprises two rollers arranged between two arc-shaped surfaces and an annular conveyor belt sleeved on the outer walls of the two rollers; the horizontal conveying direction of the annular conveyor belt is parallel to the conveying direction of the cloth; the scraper assembly comprises a scraper arranged on the annular conveyor belt and rotating around an axis in the width direction of the cloth; the scraper is used to rotate synchronously under the drive of the annular conveyor belt to scrape off impurities on the front inner wall, the rear inner wall and the side inner wall;

[0009] The impurity storage bent plate is in the shape of a concave arc plate and is arranged between the rear inner wall and the annular conveyor belt along the width direction of the cloth, and is used to scrape off and receive impurities adhered to the scraper.

[0010] In the polyester fabric production coating device of the present invention, the scraper rotates under the drive of the impurity removal conveyor, and can scrape off impurities such as dried paint on the front inner wall, the rear inner wall and the side inner wall, and can filter impurities in the storage tank, such as dried paint or fabric debris, so that no impurities gather at the bottom of the storage tank, thereby ensuring that the distance between the discharge port and the fabric is equal, so that the coating thickness of the fabric is uniform, and the molding quality of the fabric is guaranteed. Moreover, the scraper rotates in the storage tank, which also accelerates the flow of the paint and prevents the paint from drying up.

[0011] Preferably, there are two scraper assemblies; the two scraper assemblies are centrally symmetrical about the center of the endless conveyor belt; along the width direction of the cloth, one end of the scraper contacts the side inner wall, and the other end of the scraper exceeds the middle position of the storage tank; the scraper and the storage bent plate are both provided with mesh holes.

[0012] By setting two scrapers, it is possible to avoid the problems that when only one scraper is used, the scraper is too long, the movement resistance is too large when rotating in the paint, and the scraper is easy to bend and deform. In addition, since the two scrapers have overlapping areas for scraping impurities, the effect of scraping impurities is better, and there is no missed scraping area.

[0013] Preferably, the scraper assembly also includes a strip mounting seat arranged on the outer surface of the endless conveyor belt along the width direction of the cloth, and the scraper is rotatably arranged at the strip mounting seat around the length direction of the strip mounting seat through a first rotating shaft; a first torsion spring for resetting the scraper is sleeved on the first rotating shaft.

[0014] When the scraper is scraping off firmly adhering impurities, the scraper can rotate relative to the strip mounting seat, that is, the scraper is in flexible contact with the impurities, so that the scraper can continue to rotate driven by the endless conveyor belt, avoiding damage to the scraper and the driving mechanism of the impurity removal conveyor.

[0015] Preferably, the scraper assembly further comprises a limiting groove opened on the surface of the endless conveyor belt and extending to the middle of the endless conveyor belt along the width direction of the cloth, and a push rod assembled in the limiting groove;

[0016] The strip-shaped mounting seat is connected to one end of the push rod located in the middle of the endless conveyor belt by rotating around an axis perpendicular to the surface of the endless conveyor belt through a second rotating shaft; a second torsion spring for resetting the strip-shaped mounting seat is sleeved on the second rotating shaft; the axis of the second rotating shaft is eccentrically arranged at the rotating end of the strip-shaped mounting seat;

[0017] The scraper contacts one end of the side inner wall and is provided with a rounded corner at the corner away from the feeding position; the end of the push rod located on the side of the annular conveyor belt is inserted into the annular groove on the corresponding side inner wall, and the groove depth at the bottom position of the annular groove is smaller than the groove depth at other positions of the annular groove.

[0018] When the scraper rotates to the bottom of the storage tank, the side end of the scraper deflects toward the feeding position, which facilitates the paint in the middle of the storage tank to flow to the side end, thereby allowing the paint to quickly fill the storage tank, thereby facilitating the coating work of the cloth.

[0019] Preferably, the impurity removal conveyor further comprises an impurity removal drive motor arranged on the outer wall of the material storage tank; the end of the impurity storage bent plate away from the impurity removal drive motor is installed on the corresponding side inner wall through a spring, and the end of the impurity storage bent plate close to the impurity removal drive motor is provided with a connecting rod passing through the corresponding side inner wall;

[0020] A circular rotating disk is fixedly sleeved on the output shaft of the impurity removal driving motor, and grooves uniformly distributed along the circumference of the circular rotating disk are provided on the end surface of the circular rotating disk close to the impurity storage bent plate; the end of the connecting rod contacts the end surface of the circular rotating disk.

[0021] The impurities storage curved plate can scrape off the impurities adhering to the scraper and temporarily store the impurities. When the circular rotating disk rotates continuously, the impurities storage curved plate shakes back and forth along the width direction of the cloth, thereby accelerating the downward flow of the paint in the impurities storage curved plate.

[0022] Preferably, along the conveying direction of the cloth, a rotating roller is provided at the bottom of the front end of the discharge port for rotating driven by the cloth.

[0023] By arranging the rotating roller, when the cloth passes through the front end of the discharge port, the rotating roller is driven to rotate, so that the paint at this location is in a flowing state, thereby preventing the paint from drying up.

[0024] Preferably, the polyester fabric production coating device further comprises a drying mechanism disposed at the rear end of the fabric conveyor, and the drying mechanism is used for drying the fabric coated with the coating.

[0025] Preferably, the polyester cloth production coating device further comprises a feed pipe, and an outlet of the feed pipe is arranged above the impurity storage bent plate.

[0026] Preferably, the material conveyor includes a bracket, a conveying component arranged on the bracket for conveying the material, and an adjustable support mechanism located on both sides of the conveying component; the adjustable support mechanism includes a first support column vertically arranged on the bracket, a sleeve adjustably mounted on the first support column up and down by bolts, and a connecting piece connecting the sleeve and the corresponding side wall surface of the material storage tank.

[0027] Preferably, the material distribution conveyor further comprises a leveling mechanism provided on the bracket and located on both sides of the conveying assembly; the leveling mechanism is located behind the material storage tank;

[0028] The leveling mechanism includes a second support column vertically arranged on the bracket, a horizontal support rod horizontally arranged on the second support column, and a circular pressure plate rotatably arranged around the axis of the horizontal support rod; the bottom of the circular pressure plate contacts the top of the conveying assembly.

[0029] The beneficial effects are:

[0030] 1. In the polyester fabric production coating device of the present invention, the scraper rotates under the drive of the impurity removal conveyor, and can scrape off the impurities such as dried paint on the front inner wall, the rear inner wall and the side inner wall, and can filter the impurities in the storage tank, such as dried paint or fabric debris, so that there is no accumulation of impurities at the bottom of the storage tank, thereby ensuring that the distance between the discharge port and the fabric is equal, so that the coating thickness of the fabric is uniform, and the molding quality of the fabric is guaranteed. Moreover, the scraper is arranged to rotate in the storage tank, which also accelerates the flow of the paint and prevents the paint from drying up.

[0031] 2. By setting two scrapers, it is possible to avoid the problems of too long scraper, too large movement resistance when rotating in the paint, easy bending and deformation of the scraper, etc. when only one scraper is used. Moreover, since the two scrapers have overlapping areas for scraping impurities, the effect of scraping impurities is better, and there is no missed scraping area.

[0032] 3. When the scraper is scraping off firmly adhering impurities, the scraper can rotate relative to the strip mounting seat, that is, the scraper is in flexible contact with the impurities, so that the scraper can continue to rotate driven by the circular conveyor belt, avoiding damage to the scraper and the driving mechanism of the impurity removal conveyor.

[0033] 4. When the scraper rotates to the bottom of the storage tank, the side end of the scraper deflects toward the feeding position, which facilitates the paint in the middle of the storage tank to flow to the side end, so that the paint can quickly fill the storage tank, thereby facilitating the coating work of the cloth.

[0034] 5. The impurities storage curved plate can scrape off the impurities adhering to the scraper and temporarily store the impurities. When the circular rotating disk rotates continuously, the impurities storage curved plate shakes back and forth along the width direction of the fabric, thereby accelerating the downward flow of the paint in the impurities storage curved plate.

[0035] 6. By setting a rotating roller, when the cloth passes through the front end of the discharge port, the rotating roller is driven to rotate, so that the paint at this place is in a flowing state, thereby preventing the paint from drying up. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0058] Embodiment 1 of the polyester fabric production coating device provided by the present invention:

[0059] The polyester fabric production coating device of the present invention is used to perform coating treatment on polyester fabric, for example, coating polyurethane, fluorocarbon, acrylic acid, etc. on the surface of polyester fabric, and can coat and modify the surface of polyester fabric to achieve sun protection, waterproof, antibacterial and other effects. Figures 1 to 13 As shown, the polyester fabric production coating device of the present invention comprises a fabric conveyor, a storage tank 2 for storing coating material arranged above the fabric conveyor, a dust removal conveyor 3 arranged in the storage tank 2, a scraper assembly 4 and a dust storage curved plate 5. A discharge port for coating material to flow out to be coated on the surface of the fabric is provided at the bottom of the storage tank 2.

[0060] like Figure 1 As shown, the cloth conveyor includes a bracket 11 and a conveying assembly 12 arranged on the bracket 11 for conveying cloth. The cloth conveyor can be a belt conveyor. The conveying assembly 12 includes a driving wheel, a driven wheel, an annular belt sleeved on the driving wheel and the driven wheel, and a driving mechanism for driving the driving wheel to rotate, such as a cloth driving motor. When working, the cloth is first placed on the annular belt, and the cloth passes through the gap between the annular belt and the material storage tank 2, and then the paint is injected into the material storage tank 2. The paint flows out through the discharge port at the bottom of the material storage tank 2 and adheres to the cloth. The cloth adhered with the paint moves forward under the drive of the annular belt, and finally forms a coated cloth.

[0061] like Figure 1 , Figure 2 As shown, the material distribution conveyor also includes an adjustable support mechanism 13 disposed on the bracket 11 and located on both sides of the conveying assembly 12. The adjustable support mechanism 13 includes a first support column 131 vertically disposed on the bracket 11, a sleeve 132 adjustably sleeved on the first support column 131 up and down by bolts, and a connector 133 connecting the sleeve 132 and the corresponding side wall surface of the storage tank 2. The connector 133 includes a connecting column and a clamping block for clamping the top edge of the storage tank 2. The clamping block has a clamping opening with an opening facing downward for clamping the top edge of the storage tank 2. In order to improve the firmness of the connection, a bolt connector 133 may also be provided at the top edge of the clamping block and the storage tank 2.

[0062] The coating thickness of the fabric is determined by the spacing between the bottom of the storage tank 2 and the top surface of the fabric conveyor. The larger the spacing, the more coating will flow out, and the thicker the coating thickness of the fabric will be. In the present invention, the adjustable support mechanism 13 is used to adjust the spacing between the storage tank 2 and the fabric conveyor, and then adjust the thickness of the coating adhered to the fabric, which is suitable for different fabric production needs. During operation, loosen the bolts, adjust the position of the sleeve 132 and the connector 133 up and down, and then adjust the height of the storage tank 2. After adjusting to the right position, tighten the bolts to complete the adjustment of the storage tank 2, that is, to achieve the adjustment of the coating thickness of the fabric.

[0063] like Figure 1As shown, the cloth conveyor also includes a leveling mechanism 14 disposed on the bracket 11 and located on both sides of the conveying assembly 12. The leveling mechanism 14 is located in front of the storage tank 2. In the present invention, the conveying direction of the cloth is the front, and the direction opposite to the conveying direction of the cloth is the rear. The width direction of the conveying assembly 12 is the width direction of the cloth. The leveling mechanism 14 includes a second support column 141 vertically disposed on the bracket 11, a horizontal support rod horizontally disposed on the second support column 141, and a circular pressure plate 142 rotatably disposed around the axis of the horizontal support rod. The bottom of the circular pressure plate 142 contacts the top of the conveying assembly 12, specifically, the bottom of the circular pressure plate 142 contacts the top of the endless belt of the conveying assembly 12. The contact mentioned here can cause a certain pressure between the circular pressure plate 142 and the endless belt of the conveying assembly 12.

[0064] In the present invention, the conveying component 12 is started, causing the annular belt to rotate, driving the circular pressure plate 142 to rotate, thereby pressing and leveling the annular belt, ensuring that no wrinkles or the like appear on the cloth on the annular belt, ensuring the flatness of the cloth, and thereby improving the coating quality of the cloth.

[0065] like Figure 4 As shown, the top and bottom of the storage tank 2 are both provided with openings. The opening at the top of the storage tank 2 is used to inject paint. The opening at the bottom of the storage tank 2 is the above-mentioned discharge port. The storage tank 2 includes a front inner wall 21 and a rear inner wall 22 arranged in sequence along the conveying direction of the cloth, and two side inner walls 23 arranged in sequence along the width direction of the cloth and connecting the front inner wall 21 and the rear inner wall 22. The front inner wall 21 and the rear inner wall 22 both include a concave arc surface. The space formed by the two arc surfaces and the two side inner walls 23 is the storage space for the paint.

[0066] like Figure 4 As shown, the impurity removal conveyor 3 includes two rollers 31 arranged between two arc-shaped surfaces and an annular conveyor belt 32 sleeved on the two rollers 31. The horizontal conveying direction of the annular conveyor belt 32 is parallel to the conveying direction of the cloth. The axes of the two rollers 31 extend along the width direction of the cloth, and the length of the rollers 31 is equal to or slightly less than the distance between the two side inner walls 23 of the storage tank 2, so as to facilitate the rotation of the rollers 31 and the annular conveyor belt 32. The two rollers 31 are rotatably arranged at the side inner walls 23 of the storage tank 2. The two rollers 31 include an active roller and a driven roller. The impurity removal conveyor 3 can also be a belt conveyor. The impurity removal conveyor 3 also includes an impurity removal drive motor 33 for driving the active roller to rotate. The impurity removal drive motor 33 can be arranged at the outer wall of the storage tank 2, or at the first support column 131, or on the bracket 11 through a support structure.

[0067] like Figures 1 to 11As shown, the scraper assembly 4 includes a scraper 41 that is rotated around an axis in the width direction of the cloth and is arranged on the endless conveyor belt 32. The scraper 41 is used to rotate synchronously under the drive of the endless conveyor belt 32 to scrape off impurities on the front inner wall 21, the rear inner wall 22 and the side inner wall 23. Specifically, the scraper 41 is in the shape of a long flat plate, and mesh holes are opened on it. The scraper 41 is extended along the width direction of the cloth, and the side edge of the scraper 41 away from the endless conveyor belt 32 is used to contact the arc surface of the front inner wall 21 or the rear inner wall 22, and at least one side edge of the two ends of the scraper 41 is in contact with the corresponding side inner wall 23. When the scraper 41 moves to the bottom of the storage tank 2, there is a gap between the scraper 41 and the cloth, that is, the scraper 41 does not contact the cloth.

[0068] In the present invention, the impurity removal conveyor 3 is started, so that the annular conveyor belt 32 rotates, driving the scraper 41 on the annular conveyor belt 32 to rotate synchronously. The scraper 41 can scrape off the impurities such as dried paint on the front inner wall 21, the rear inner wall 22 and the side inner wall 23, and can filter the impurities in the storage tank 2, such as dried paint or cloth debris, and adhere to the scraper 41, and finally store them in the storage bent plate 5, so that there is no accumulation of impurities at the bottom of the storage tank 2, thereby ensuring that the distance between the discharge port and the cloth is equal, so that the coating thickness of the cloth is uniform, and the molding quality of the cloth is guaranteed. Moreover, the scraper 41 is arranged to rotate in the storage tank 2, which also accelerates the flow of the paint and prevents the paint from drying up.

[0069] like Figure 4 and Figure 8 As shown, there are two scraper assemblies 4. The two scraper assemblies 4 are centrally symmetrical about the center of the endless conveyor belt 32. Along the width direction of the cloth, one end of the scraper 41 contacts the side inner wall 23, and the other end of the scraper 41 exceeds the middle position of the storage tank 2. This arrangement ensures that the two scrapers 41 scrape the impurities in the storage tank 2 in an overlapping area.

[0070] In the present application, two scraper assemblies 4 are provided, so that there are also two scrapers 41, each scraper 41 is used to scrape impurities on the inner wall of one side of the storage tank 2, so as to avoid problems such as the length of the scraper 41 being too long, the movement resistance being too large when rotating in the paint, and the scraper 41 being easy to bend and deform. Moreover, since there are overlapping areas for the two scrapers 41 to scrape impurities, the effect of scraping impurities is better, and there is no area to be scraped.

[0071] like Fig. 9 and Fig.11As shown, the scraper assembly 4 also includes a strip mounting seat 42 provided on the outer surface of the endless conveyor belt 32 along the width direction of the cloth, and the scraper 41 is rotatably provided at the strip mounting seat 42 around the length direction of the strip mounting seat 42. A first rotating shaft is provided at the end of the scraper 41 for cooperating with a first rotating groove at the end of the strip mounting seat 42. A first torsion spring for resetting the scraper 41 is sleeved on the first rotating shaft, and the two ends of the first torsion spring are respectively connected to the scraper 41 and the strip mounting seat 42.

[0072] When the scraper 41 scrapes off impurities driven by the endless conveyor belt 32, if some dried paint adheres firmly to the inner wall of the storage tank 2, the scraper 41 is in rigid contact with the impurities, which may damage the scraper 41 and the driving mechanism of the impurity removal conveyor 3. In the present invention, when the scraper 41 scrapes off the impurities that adhere firmly, the scraper 41 can rotate relative to the strip mounting seat 42, that is, the scraper 41 is in flexible contact with the impurities, so that the scraper 41 can continue to rotate under the drive of the endless conveyor belt 32, avoiding damage to the scraper 41 and the driving mechanism of the impurity removal conveyor 3. When the scraper assembly 4 leaves the position of the impurities that adhere firmly, the scraper 41 rotates in the opposite direction relative to the strip mounting seat 42 under the reset action of the first torsion spring to achieve reset and continue the scraping work.

[0073] Moreover, the scraper assembly 4 moves to the debris storage bent plate 5 driven by the annular conveyor belt 32, and the scraper 41 rotates relative to the strip mounting seat 42 under the obstruction of the debris storage bent plate 5. The debris storage bent plate 5 can also scrape off impurities adhered to the scraper 41. When the scraper assembly 4 leaves the position of the debris storage bent plate 5, the scraper 41 rotates in the opposite direction relative to the strip mounting seat 42 under the resetting action of the first torsion spring to achieve resetting and continue the scraping work.

[0074] like Figures 9 to 13 As shown, the scraper assembly 4 also includes a limiting groove which is opened on the outer surface of the endless conveyor belt 32 and extends to the middle of the endless conveyor belt 32 along the width direction of the cloth, and a push rod 43 assembled in the limiting groove. One end of the strip mounting seat 42 away from the side inner wall 23 is rotatably connected to the end of the push rod 43 located in the middle of the endless conveyor belt 32 around an axis perpendicular to the surface of the endless conveyor belt 32. The corresponding end of the push rod 43 is provided with a second rotating shaft 44 for cooperating with the second rotating groove at the end of the strip mounting seat 42. A second torsion spring for resetting the strip mounting seat 42 is sleeved on the second rotating shaft 44, and the two ends of the second torsion spring are respectively connected to the push rod 43 and the strip mounting seat 42. The axis of the second rotating shaft 44 is eccentrically arranged at the rotating end of the strip mounting seat 42. Specifically, the axis of the second rotating shaft 44 is arranged on the side of the rotating end of the strip mounting seat 42 away from the feeding position, as shown in FIG. Fig.11 and Fig.12As shown. A rounded corner 411 is provided at the corner of the scraper 41 that contacts one end of the side inner wall 23 and is away from the feeding position. One end of the push rod 43 located on the side of the annular conveyor belt 32 is inserted into the annular groove on the corresponding side inner wall 23, and the groove depth at the bottom position of the annular groove is less than the groove depth at the rest of the annular groove. Specifically, a rotating seat 24 is provided on the side inner wall 23, and two rollers 31 are rotatably arranged on the rotating seat 24, and an annular groove is provided on the rotating seat 24. The bottom position of the annular groove is a shallow groove 241, and the rest of the annular groove is a deep groove 242, and the bottom wall of the deep groove 242 is connected to the bottom wall of the shallow groove 241 through a first guide slope.

[0075] The paint in the storage tank 2 is mainly stored between the impurity removal conveyor 3 and the material distribution conveyor, and the feeding position is located in the middle position above the rear end of the storage tank 2. Due to the poor fluidity of the paint, it is not easy for the paint to flow and diffuse to both sides of the storage tank 2 after falling into the middle of the storage tank 2 from the feeding position, which is not conducive to the coating work of the material distribution.

[0076] In the present invention, when the endless conveyor belt 32 drives the scraper assembly 4 to move to the top and front and rear ends of the storage tank 2, the push rod 43 is inserted into the deep groove 242, and the scraper 41 extends along the width direction of the cloth. When the endless conveyor belt 32 drives the scraper assembly 4 to move to the bottom position of the storage tank 2, the push rod 43 slides from the deep groove 242 into the shallow groove 241, and the push rod 43 pushes the strip mounting seat 42 and the scraper 41 to move toward the corresponding side inner wall 23. Since the strip mounting seat 42 and the scraper 41 are in contact with the side inner wall 23, and since the strip mounting seat 42 is eccentrically arranged, the corresponding end of the scraper 41 is provided with a rounded corner 411 away from the feeding position, so that the strip mounting seat 42 is subjected to a force close to the feeding position under the thrust of the push rod 43, thereby causing the scraper 41 to deflect relative to the push rod 43, and the deflection direction is close to the feeding position, that is, the length direction of the scraper 41 and the width direction of the cloth form a certain deflection angle. Since the side end of the scraper 41 deflects toward the feeding position, it is convenient for the paint in the middle of the storage tank 2 to flow toward the side end, so that the paint can quickly fill the storage tank 2, thereby facilitating the coating work of the cloth.

[0077] like Figures 1 to 4 As shown, the impurity storage curved plate 5 is in the shape of a concave arc plate, and is arranged between the rear inner wall 22 and the endless conveyor belt 32 along the width direction of the cloth, and is used to scrape and receive impurities adhered to the scraper 41. Specifically, the impurity storage curved plate 5 is arranged at the rear inner wall 22. The impurity storage curved plate 5 is provided with mesh holes.

[0078] In the present invention, the curved plate-shaped impurity storage bent plate 5 can scrape off impurities adhering to the scraper 41 and store the impurities, and the paint can flow into the storage tank 2 through the mesh of the impurity storage bent plate 5. By providing the impurity storage bent plate 5, it is convenient to scrape and centrally store the impurities on the scraper 41, which is convenient for subsequent cleaning work.

[0079] In other embodiments, the impurity storage curved plate 5 is rotatably disposed at the rear inner wall 22 via a third rotating shaft, and a third torsion spring is sleeved on the third rotating shaft for resetting the impurity storage curved plate 5. When the scraper 41 rotates to contact the impurity storage curved plate 5, the impurity storage curved plate 5 can rotate a certain angle relative to the rear inner wall 22, which can scrape off impurities adhering to the scraper 41 on the one hand, and does not hinder the scraper 41 from continuing to rotate on the other hand.

[0080] like Figure 5 and Figure 6 As shown, the end of the storage curved plate 5 away from the impurity removal driving motor 33 is installed on the corresponding side inner wall 23 through a spring 51, and the end of the storage curved plate 5 close to the impurity removal driving motor 33 is provided with a connecting rod 52 that passes through the corresponding side inner wall 23. A circular rotating disk 53 is fixedly sleeved on the output shaft of the impurity removal driving motor 33, and the end surface of the circular rotating disk 53 close to the storage curved plate 5 is provided with grooves 531 uniformly distributed along the circumference of the circular rotating disk 53. A second guiding inclined surface is provided between the bottom wall of the groove 531 and the end surface of the circular rotating disk 53. The end of the connecting rod 52 away from the storage curved plate 5 is in contact with the corresponding end surface of the circular rotating disk 53.

[0081] In the present invention, the impurity removal driving motor 33 rotates, driving the circular rotating disk 53 to rotate, and the circular rotating disk 53 contacts and cooperates with the connecting rod 52. When the connecting rod 52 is inserted into the groove 531, the impurity storage curved plate 5 moves toward the circular rotating disk 53 under the elastic force of the spring 51. When the connecting rod 52 is separated from the groove 531 and contacts the end surface of the impurity storage curved plate 5, the impurity storage curved plate 5 moves away from the circular rotating disk 53 under the push of the connecting rod 52. Therefore, under the continuous rotation of the circular rotating disk 53, the impurity storage curved plate 5 shakes back and forth along the width direction of the cloth, thereby accelerating the downward flow of the paint in the impurity storage curved plate 5.

[0082] like Figures 2 to 5 As shown, the polyester fabric production coating device also includes a feed pipe 8, and the outlet of the feed pipe 8 is arranged above the storage bent plate 5. A piece of cloth strip can also be wrapped around the outlet of the feed pipe 8 so that the paint can flow down evenly, and the cloth strip can expand the range of the discharge port to avoid the accumulation of paint.

[0083] In the present invention, the paint is transported through the feed pipe 8 and flows from the outlet of the feed pipe 8 to the top of the storage curved plate 5, which can filter the paint. The reciprocating shaking of the storage curved plate 5 also facilitates the rapid falling of the paint.

[0084] like Figure 4As shown, along the conveying direction of the cloth, a rotating roller 6 is provided at the bottom of the front end of the discharge port for rotating under the drive of the cloth. In the present invention, the cloth coated with the paint is discharged through the front end of the discharge port. In order to prevent the paint from drying up at the front end of the discharge port and affecting the coating quality, a rotating roller 6 is provided. When the cloth passes through the front end of the discharge port, the rotating roller 6 is driven to rotate, so that the paint at this location is in a flowing state, thereby preventing the paint from drying up.

[0085] like Figure 1 As shown, the polyester fabric production coating device also includes a drying mechanism 7 arranged at the rear end of the fabric conveyor, and the drying mechanism 7 is used to dry the fabric coated with the coating. The drying mechanism 7 is formed with a drying chamber that runs through the conveying direction of the fabric, and the fabric conveyor passes through the drying chamber. The drying mechanism 7 may include a heating component and a blowing component, the heating component generates heat, and the blowing component blows the heat toward the fabric. The heating component may be a heating wire or a heating tube, and the blowing component may be a fan.

[0086] In the present invention, the cloth coated with paint is conveyed to the drying chamber of the drying mechanism 7 by the cloth conveyor, so that the paint can be dried quickly, thereby ensuring the coating quality of the cloth and accelerating the production efficiency of the coated cloth.

[0087] The overall working process of the present invention is as follows:

[0088] The coating process of the cloth: the conveying component 12 of the cloth conveyor conveys the cloth forward, and the cloth adheres to the paint in the storage tank 2 and is output from the front end of the storage tank 2, and finally undergoes drying treatment by the drying mechanism 7 to form a finished product.

[0089] Impurity removal process: While the coating is being applied, the impurity removal conveyor 3 is started, causing the annular conveyor belt 32 to rotate, driving the scraper 41 on the annular conveyor belt 32 to rotate synchronously. When the scraper 41 rotates to the bottom of the storage tank 2, the push rod 43 slides from the deep groove 242 into the shallow groove 241, and the push rod 43 pushes the strip mounting seat 42 and the scraper 41 to move toward the corresponding side inner wall 23, so that the strip mounting seat 42 drives the scraper 41 to deflect toward the feeding position relative to the push rod 43 under the thrust of the push rod 43, so that the paint flowing into the middle of the storage tank 2 flows toward the side end, and then the paint can quickly fill the storage tank 2. When the scraper 41 is at the bottom of the storage tank 2, the impurities on the inner wall of the storage tank 2 can be scraped off. When the scraper 41 leaves the bottom of the storage tank 2, the push rod 43 slides from the shallow groove 241 into the deep groove 242, and the strip mounting seat 42 and the scraper 41 are reset under the action of the second torsion spring, and the length direction of the strip mounting seat 42 and the scraper 41 is parallel to the width direction of the cloth. Driven by the endless conveyor belt 32, the scraper 41 can scrape the impurities at the front inner wall 21 and the rear inner wall 22 in turn. When the scraper 41 rotates to the rear inner wall 22 and contacts the storage curved plate 5, the scraper 41 rotates relative to the strip mounting seat 42 under the obstruction of the storage curved plate 5, and can scrape the impurities adhered to the scraper 41, and continue to rotate. When the scraper 41 leaves the storage curved plate 5, the scraper 41 is reset under the action of the first torsion spring, and the scraping work continues until the scraper 41 rotates to the bottom of the storage tank 2 again. The scraper 41 circulates and rotates to continuously scrape away impurities on the front inner wall 21 , the rear inner wall 22 and the side inner wall 23 .
