Description

Technical Field

[0001] This invention belongs to the field of artificial turf production technology, specifically referring to a base fabric coating device for artificial turf production. Background Technology

[0002] During the production process of artificial turf, in order to prevent the grass fibers from falling off, a latex coating is applied to the back of the artificial turf base fabric to help fix it.

[0003] When applying adhesive to artificial turf, the required amount of adhesive varies depending on the thickness of the base fabric. Thicker and harder base fabrics generally require more adhesive. Insufficient adhesive will prevent the glue from penetrating deeply into the base fabric, resulting in weak root fixation. Existing adhesive application systems involve cumbersome and inconvenient adjustments to the adhesive amount. Precise control of the adhesive amount is primarily achieved through the gap and angle of the scraper. Even slight deviations can cause fluctuations in the adhesive amount, affecting the consistency of the entire roll of turf quality. Current adhesive application systems do not adjust the adhesive supply when adjusting the scraper angle. During scraper application, an adhesive accumulation zone forms in front of the scraper. The stability of this accumulation zone is crucial for achieving a uniform adhesive layer. Adjusting the scraper angle directly alters the shape and height of the adhesive accumulation zone. A larger scraper angle requires a higher and larger accumulation zone to maintain stable application, while a smaller angle results in a smaller accumulation zone.

[0004] If the glue output does not change accordingly, the following problems will occur: 1. Increased angle, unchanged glue output: The glue accumulation area is too small and cannot be maintained stably, resulting in a decrease in glue output instead of an increase, and serious streaks and glue breaks appear, with extremely uneven glue layer.

[0005] 2. Decreasing the angle without changing the glue output: The glue accumulation area will become too high and too large, and too much glue will overflow from both sides of the scraper, causing waste and pollution. More seriously, excessive fluid pressure may "force" the scraper open, leading to an uncontrolled increase in the amount of glue applied in some areas, or causing glue splatter.

[0006] After adjusting the scraper angle, the amount of adhesive dispensed not only needs to be finely adjusted accordingly, but also must be adjusted in the same direction and in coordination according to the direction of the angle change; otherwise, a high-quality and stable adhesive application effect cannot be obtained. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a base fabric adhesive application device for artificial turf production. The device can adjust the adhesive supply and scraper height according to the thickness of the base fabric so that the gap between the scraper and the base fabric is adapted to the adhesive supply and the thickness of the base fabric. At the same time, the scraper angle can be adjusted, and the adhesive supply can be automatically fine-tuned according to the scraper angle adjustment to avoid excessive adhesive supply.

[0008] The technical solution adopted by this invention is as follows: This invention provides a base fabric coating device for artificial turf production, comprising a frame. A fixed conveying mechanism for conveying the base fabric is provided at the bottom of the frame. An adjusting cylinder is provided at the top of the frame. A top plate is provided at the bottom of the adjusting cylinder. A self-adjusting pressure roller assembly, a follow-up self-adjusting glue supply mechanism, and a follow-up adjusting scraper mechanism are sequentially arranged along the length of the top plate. A thickness detection mechanism for detecting the thickness of the base fabric is provided on one side of the self-adjusting pressure roller assembly. The follow-up adjusting scraper mechanism includes a scraping bracket slidably disposed at the bottom of the top plate and an angle adjustment mechanism disposed at the bottom of the scraping bracket. A scraper is provided on the angle adjustment mechanism. The follow-up self-adjusting glue supply mechanism includes a glue supply adjustment mechanism and a glue supply fine-tuning mechanism. The glue supply adjustment mechanism includes a glue supply component and a movable part. The movable part is connected to the glue supply component. A glue outlet is provided at the bottom of the movable part. The movable part is slidably connected to the glue supply component to adjust the communication area between the movable part and the glue supply component. The movable part adopts… The structure includes a telescopic mechanism, wherein the glue supply fine-tuning mechanism is connected to and drives the movable part to extend and retract; a first linkage mechanism is provided between the thickness detection mechanism, the glue supply adjustment mechanism, and the scraper bracket; a second linkage mechanism is provided between the angle adjustment mechanism and the glue supply fine-tuning mechanism; the first linkage mechanism includes a controller, a scraper drive component, and a glue supply drive component; the glue supply drive component is located between the glue supply assembly and the movable part, and drives the movable part to slide relative to the glue supply assembly to adjust the communication area between the movable part and the glue supply assembly; the scraper drive component is located between the top plate and the scraper bracket and drives the scraper bracket to rise and fall to adjust the height of the scraper to the base fabric; the controller is located on the top plate; the second linkage mechanism includes an angle sensor and a fine-tuning drive unit; the angle sensor is located on the scraper; the fine-tuning drive unit is connected to the glue supply fine-tuning mechanism and drives the glue supply fine-tuning mechanism to move; the controller is electrically connected to the scraper drive component, the glue supply drive component, the thickness detection mechanism, the fine-tuning drive unit, and the angle sensor.

[0009] Preferably, the glue supply assembly includes a glue storage tank and a glue supply box. The glue storage tank is located on the upper wall of the top plate, and a mounting rod is provided on the bottom wall of the top plate. The glue supply box is located at the bottom end of the mounting rod. A glue supply channel is provided between the glue storage tank and the glue supply box. An adjusting slide tube is provided on the bottom wall of the glue supply box, and the adjusting slide tube is equidistantly distributed along the length direction of the glue supply box. The movable component includes an adjusting slide rod and an adjusting slide cylinder. The adjusting slide rod adopts a telescopic structure, and the adjusting slide cylinder is slidably and sealedly connected inside the adjusting slide tube. The side wall of the adjusting slide cylinder is provided with a... The adhesive supply box has a strip-shaped through-hole. A limiting tube is connected to the upper wall of the supply box. An anti-overflow baffle is installed inside the limiting tube. The anti-overflow baffle is slidably and sealingly connected to the limiting tube. The middle part of the adjusting slide rod is fixedly inserted through the anti-overflow baffle. The bottom end of the adjusting slide rod is connected to the adjusting slide cylinder. A sealing spring is installed between the upper end of the limiting tube and the anti-overflow baffle. The upper ends of multiple sets of adjusting slide rods are connected to a locking plate. The locking plate has locking components evenly distributed along the length direction. The locking components correspond one-to-one with the adjusting slide rods. The locking plate is connected to the adhesive supply drive component.

[0010] Initially, the sealing spring pushes the anti-overflow baffle down, and the anti-overflow baffle drives the adjusting slide cylinder down through the adjusting slide rod to completely retract into the adjusting slide tube. At this time, the strip-shaped through hole is completely blocked by the side wall of the adjusting slide tube, and the adjusting slide cylinder is not connected to the glue supply box.

[0011] More specifically, the locking plate is provided with locking sliding holes equidistantly distributed along its length direction, which are adapted to the adjusting slide rod. The adjusting slide rod is slidably disposed within the locking sliding holes. The locking plate is provided with locking cavities equidistantly distributed along its length direction, communicating with the locking sliding holes. The locking assembly is disposed within the locking cavity. The locking assembly includes a locking electric push rod, a locking push shaft, and an active wedge block. The locking electric push rod is disposed within the locking cavity. A strip-shaped sliding hole is provided through the locking cavity. The push shaft is slidably disposed within a strip-shaped sliding hole, and the engaging push shaft is disposed at the output end of the engaging electric push rod. The active wedge block is slidably engaged within the engaging cavity. The active wedge block is inclined on the side near the engaging push shaft. A magnet block is provided on the inner wall of the engaging cavity. The magnet block generates a magnetic attraction force on the active wedge block and attracts the active wedge block to retract into the engaging cavity. The side wall of the adjusting slide rod is provided with an engaging groove adapted to the active wedge block. The active wedge block is made of ferromagnetic metal.

[0012] Initially, the locking electric actuator is in the extended state. At this time, the locking push shaft is in contact with the end of the active wedge block that is further from the strip-shaped sliding hole. The pair of active wedge blocks generate a magnetic attraction force. The locking push shaft pushes the active wedge block to overcome the magnetic attraction force, causing it to extend out of the locking cavity and lock into the locking groove. When the locking plate moves up, the locking plate drives the adjusting slide rod that is locked with the active wedge block to move up through the active wedge block. If there is no base fabric below the set of adjusting slide cylinders, that is, the set of adjusting slide cylinders does not need to supply glue, the locking electric actuator corresponding to the set of adjusting slide rods is controlled to retract. The locking push shaft moves to the end of the active wedge block that is further from the strip-shaped sliding hole. The pair of active wedge blocks generate a magnetic attraction force, so that the inclined side of the active wedge block is always in contact with the locking push shaft. Under the action of magnetic attraction force, the active wedge block gradually retracts into the locking cavity and disengages from the locking groove. Therefore, when the locking plate moves up, the set of adjusting slide rods will not move up with it.

[0013] Furthermore, the adjusting slide rod includes an upper slide rod and a lower slide rod that are slidably connected. The engaging groove is provided on the upper slide rod, and the upper slide rod slides through the engaging sliding hole. The upper end of the lower slide rod extends upward through a limiting tube. The glue supply fine-tuning mechanism includes a fine-tuning plate, a worm gear, a worm wheel, and a fine-tuning screw. The fine-tuning plate is engaged with multiple sets of lower slide rods. The fine-tuning screw is rotatably mounted on the side wall of the engaging plate. The side wall of the fine-tuning plate is provided with a fine-tuning screw seat, which is threadedly connected to the fine-tuning screw. The worm wheel is coaxially fixed to the fine-tuning screw. The worm gear is rotatably mounted on the engaging plate, and the worm gear meshes with the worm wheel.

[0014] Preferably, the fine-tuning plate is provided with fine-tuning sliding holes that are adapted to the sliding rod at equal intervals along its length. The sliding rod slides through the fine-tuning sliding holes. The fine-tuning plate is provided with fine-tuning cavities that communicate with the fine-tuning sliding holes at equal intervals along its length. A fine-tuning wedge block is slidably provided in the fine-tuning cavity. A second magnet block is provided on the inner wall of the fine-tuning cavity. A fine-tuning groove adapted to the fine-tuning wedge block is provided on the side wall of the sliding rod. The fine-tuning wedge block is made of ferromagnetic metal. A second strip-shaped sliding hole is provided through the fine-tuning cavity. The second strip-shaped sliding hole is located directly below the first strip-shaped sliding hole. The engaging push shaft slides downward through the second strip-shaped sliding hole. The second magnet block generates a magnetic attraction force on the fine-tuning wedge block and attracts the inclined edge of the fine-tuning wedge block to always be in contact with the engaging push shaft. Guide rails are provided on both sides of the fine-tuning wedge block and on both sides of the active wedge block.

[0015] Initially, the locking electric actuator is in the extended state. At this time, the locking push shaft is in contact with the end of the fine-tuning wedge block that is further away from the second strip-shaped sliding hole. The second magnet block generates a magnetic attraction force on the fine-tuning wedge block. The locking push shaft pushes the fine-tuning wedge block to overcome the magnetic attraction force, causing it to extend out of the fine-tuning cavity and lock into the fine-tuning slot. When the fine-tuning plate moves up, the fine-tuning plate drives the sliding rod that is locked with the fine-tuning wedge block to move up through the fine-tuning wedge block. If there is no base fabric below this set of adjusting slide cylinders, that is, this set of adjusting slide cylinders does not need to supply glue, then the locking electric actuator corresponding to this set of adjusting slide cylinders is controlled to retract, and the locking push shaft moves to the end of the fine-tuning wedge block that is further away from the second strip-shaped sliding hole. At the end of the sliding hole two with a smaller distance, the magnet two generates a magnetic attraction force on the fine-tuning wedge block, causing the fine-tuning wedge block to gradually retract into the fine-tuning cavity under the action of the magnetic attraction force and disengage from the fine-tuning groove. Thus, when the fine-tuning screw rotates, the fine-tuning screw drives the fine-tuning plate to move down for fine-tuning through the fine-tuning screw seat. The sliding rod that is not engaged with the fine-tuning wedge block will not move down with it. The fine-tuning plate only drives the sliding rod that is engaged with the fine-tuning wedge block to move down. The downward movement of the sliding rod drives the adjusting slide cylinder to move down and retract into the adjusting slide tube, which shortens the connection length between the strip-shaped through hole and the glue supply box, reduces the connection area between the moving part and the glue supply assembly, and fine-tunes the glue supply amount.

[0016] Preferably, the self-adjusting pressure roller assembly includes a fixed plate, a self-adjusting slide cylinder, a compression spring, a first slide plate, a pressure sensor, a self-adjusting slide rod, and a pressure roller body. The fixed plate is located at the bottom end of the top plate. The self-adjusting slide cylinders are symmetrically arranged on the bottom wall of the fixed plate. The compression spring is located on the inner top wall of the self-adjusting slide cylinder. The first slide plate is located at the bottom end of the compression spring and slides within the self-adjusting slide cylinder. A second slide plate slides within the self-adjusting slide cylinder and is located below the first slide plate. The bottom end of the self-adjusting slide cylinder has a sliding hole. The upper end of the self-adjusting slide rod passes through the sliding hole and is located within the self-adjusting slide cylinder, connecting to the second slide plate. The pressure sensor is located on the upper wall of the second slide plate. The bottom end of the self-adjusting slide rod has a mounting part. The pressure roller body is rotatably mounted between the mounting parts. The thickness detection mechanism is located on the side wall of the mounting part.

[0017] Furthermore, the fixed conveying mechanism has a fixed plate on its side wall, which is located directly below the thickness detection mechanism. The thickness detection mechanism includes a fixed frame and a distance sensor. The fixed frame is located on the side wall of the mounting part, and the distance sensor is located on the bottom wall of the fixed frame. The fixed frame is located directly above the top plate. The bottom wall of the distance sensor is at the same horizontal level as the bottom end of the pressure roller body, and the upper wall of the fixed plate is at the same horizontal level as the top end of the fixed conveying mechanism.

[0018] The upper wall of the coating support is symmetrically provided with coating guide posts, and the top plate is provided with coating guide holes adapted to the coating guide posts. The coating support is slidably disposed on the bottom wall of the top plate through the coating guide posts and coating guide holes.

[0019] Specifically, the angle adjustment mechanism includes an arc-shaped sliding plate, which is symmetrically arranged on both sides of the scraper bracket. The side wall of the arc-shaped sliding plate is coaxially provided with an arc-shaped first sliding hole and a second sliding hole. The scraper includes a mounting base and a scraper body located at the bottom of the mounting base. The side wall of the mounting base is provided with a first sliding shaft and a second sliding shaft. The first sliding shaft is slidably engaged in the first sliding hole, and the second sliding shaft is slidably engaged in the second sliding hole. The ends of the first sliding shaft and the second sliding shaft are connected to a push plate. The side wall of the scraper bracket is rotatably connected to an electric push rod II. The output end of the electric push rod II is rotatably connected to the push plate. The bottom end of the scraper body is located at the axis of the first sliding hole.

[0020] The electric push rod extends and drives the first and second sliding shafts to slide along the first and second sliding holes via the push plate, thereby causing the scraper to rotate around the bottom of the scraper to adjust the angle.

[0021] The first linkage mechanism includes a controller, a scraping drive, and a glue supply drive. The glue supply drive is located between the glue supply box and the locking plate. The scraping drive is located between the top plate and the scraping bracket. The controller is located on the top plate and is electrically connected to the scraping drive, the glue supply drive, and the distance sensor, respectively.

[0022] After the fixed conveying mechanism and the pressure roller body press the artificial turf base fabric, the controller controls the distance measuring sensor to detect the thickness of the base fabric. Based on the detection results, the controller controls the scraping drive and the glue supply drive to extend to appropriate lengths. The thicker the base fabric, the greater the extension length of the scraping drive and the glue supply drive, the greater the upward movement distance of the clamping plate, and the more glue is supplied by the glue supply adjustment mechanism. The greater the extension length of the scraping drive, the greater the upward movement distance of the scraping bracket, the larger the gap between the scraper and the base fabric, and the more glue is applied.

[0023] More specifically, the fine-tuning drive unit includes a fine-tuning motor and a displacement sensor. The fine-tuning motor is mounted on the locking plate, and its output end is connected to the worm gear. The displacement sensor is located between the locking plate and the fine-tuning plate. The fine-tuning motor and the displacement sensor are electrically connected to the controller.

[0024] Preferably, the bottom wall of the adjusting slide tube is arc-shaped, the glue supply box has a swing shaft on both sides, a swing plate is fixedly connected to the swing shaft, the bottom end of the swing plate is connected to an arc-shaped baffle, the side wall of the glue supply box is provided with a switch motor, the output end of the switch motor is connected to the swing shaft, the swing shaft, the arc-shaped baffle and the arc-shaped bottom wall of the adjusting slide tube are coaxially arranged, and the upper wall of the arc-shaped baffle slides against the bottom wall of the adjusting slide tube.

[0025] The switch motor drives the swing shaft to rotate, and the swing shaft drives the arc-shaped baffle to rotate through the swing plate, thereby sealing or opening the bottom end of the adjusting slide tube.

[0026] Preferably, the fixed conveying mechanism includes a fixed frame, a fixed roller, and a conveyor belt. The fixed frame is mounted on the inner bottom wall of the platform. The fixed roller and the conveyor belt are rotatably mounted in the fixed frame from front to back. The pressure roller body is located directly above the fixed roller. The side wall of the fixed frame is equipped with a first conveyor motor and a second conveyor motor. The output end of the first conveyor motor is connected to the fixed roller and drives the fixed roller to rotate. The output end of the second conveyor motor is connected to the conveyor belt and drives the conveyor belt to drive the transmission. The platform is arranged in a right-angled C-shape. The upper wall of the fixed plate, the upper wall of the conveyor belt, and the apex of the fixed roller are at the same horizontal height.

[0027] The artificial turf base fabric is pressed between the fixed roller and the self-adjusting pressure roller assembly by the downward movement of the self-adjusting pressure roller assembly. The rotation of the fixed roller drives the artificial turf base fabric to be conveyed, and at the same time, the conveyor belt also drives the artificial turf base fabric to be conveyed. The conveying speed of the fixed roller and the conveyor belt are kept at the same speed.

[0028] Preferably, the glue supply box and the glue storage tank are each equipped with an electric heating plate.

[0029] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The thickness of the base fabric is detected by a thickness detection mechanism, and the glue supply and the gap between the scraper and the base fabric are automatically adjusted to realize the linkage between glue supply adjustment and scraper adjustment. This ensures that the glue supply matches the thickness of the base fabric, avoids insufficient or excessive glue application, and at the same time makes the glue supply and scraper gap compatible.

[0030] 2. The glue supply fine-tuning mechanism is linked with the scraper angle, so that the scraper angle and glue supply are adjusted in tandem. The fine-tuning motor drives the fine-tuning plate to move slightly, so as to achieve fine-tuning of the glue supply, ensure the stability of the glue accumulation area, avoid problems such as stripes, glue breaks, and uneven glue application, improve the quality consistency of the entire roll of turf, and improve the uniformity and consistency of glue application.

[0031] 3. The self-adjusting pressure roller assembly ensures that the base fabric is conveyed flat, avoiding wrinkles or shifting, and further ensuring the adhesive coating effect.

[0032] 4. By independently controlling the engagement of the sliding rod and the locking plate through multiple sets of locking components, the independent control of multiple sets of adjusting sliding cylinders can be achieved. The adhesive can be selectively supplied according to the width of the base fabric, which is suitable for the adhesive application needs of artificial turf base fabrics of different widths.

The output end of the first conveyor motor is connected to the fixed roller 81 and drives the fixed roller 81 to rotate. The output end of the second conveyor motor is connected to the conveyor belt 82 and drives the conveyor belt 82 to drive. The platform 1 is arranged in a right-angled C-shape. The upper wall of the fixed plate 9, the upper wall of the conveyor belt 82, and the apex of the fixed roller 81 are at the same horizontal height.

[0052] To prevent the adhesive from solidifying, the adhesive supply box 29 and the adhesive storage tank 28 are respectively equipped with electric heating plates.

[0053] In practical use, firstly, the adjusting cylinder 3 drives the top plate 4 upward, causing the pressure roller body 23 to move upward away from the fixed roller 81. Then, the artificial turf base fabric to be coated is placed above the fixed roller 81. Next, the adjusting cylinder 3 drives the top plate 4 downward. The downward movement of the top plate 4 causes the self-adjusting pressure roller assembly 5 to approach the artificial turf base fabric, pressing the base fabric between the fixed roller 81 and the pressure roller body 23. The pressure roller body 23 drives the self-adjusting slide bar 22 upward along the self-adjusting slide cylinder 18. The self-adjusting slide bar 22 drives the second slide plate 24 upward, approaching the first slide plate 20 and squeezing the pressure sensor 21. The pressure sensor 21 generates an electrical signal under pressure and sends it to the controller 74. When the pressure value detected by the pressure sensor 21 reaches the preset value, the controller 74 controls the adjusting cylinder 3 to stop extending. When the artificial turf base fabric is securely clamped between the fixed roller 81 and the pressure roller body 23, initially, the sealing spring 38 pushes the anti-overflow baffle 31 downward. The anti-overflow baffle 31 drives the adjusting slide cylinder 35 downward through the adjusting slide rod 30 and completely retracts into the adjusting slide tube 34. At this time, the strip-shaped through hole 36 is completely blocked by the side wall of the adjusting slide tube 34, the adjusting slide cylinder 35 is not connected to the glue supply box 29, the glue in the glue supply box 29 will not flow out, and the arc-shaped baffle 63 is located at the bottom end of the adjusting slide tube 34 to seal it. The locking electric push rod 43 is in the extended state. At this time, the locking push shaft 44 is in contact with the end of the active wedge block 45 that is farther from the first strip-shaped slide hole 46, and the locking push shaft 44 is in contact with the end of the fine-tuning wedge block 57 that is farther from the second strip-shaped slide hole 59. The locking push shaft 44 pushes... The active wedge block 45 overcomes the magnetic attraction, extending from the engagement cavity 42 and engaging in the engagement groove 84. The engagement push shaft 44 pushes the fine-tuning wedge block 57 to overcome the magnetic attraction, extending from the fine-tuning cavity 56 and engaging in the fine-tuning groove 85. When the engagement plate 39 moves upward, the engagement plate 39 drives the adjusting slide rod 30 engaged with the active wedge block 45 to move upward via the active wedge block 45. When the fine-tuning plate 50 moves upward, the fine-tuning plate 50 drives the lower slide rod 49 engaged with the fine-tuning wedge block 57 to move upward via the fine-tuning wedge block 57. The operator adjusts the number of engagements between the engagement plate 39 and the adjusting slide rod 30 according to the width of the base fabric by controlling the switch. If there is no base fabric below the set of adjusting slide cylinders 35, that is, the set of adjusting slide cylinders 35 does not need to be supplied with glue, then the control is adjusted to the corresponding number of adjusting slide rods 30. The engaging electric actuator 43 retracts, and the engaging push shaft 44 moves to the end where the distance between the active wedge block 45 and the first strip-shaped sliding hole 46 is smaller. The first magnet block 47 generates a magnetic attraction force on the active wedge block 45, ensuring that the inclined edge of the active wedge block 45 always adheres to the engaging push shaft 44. As the engaging push shaft 44 moves, the active wedge block 45 gradually retracts into the engaging cavity 42 under the action of magnetic attraction and disengages from the engaging groove 84. Thus, when the engaging plate 39 moves upward, the adjusting slide rod 30 will not move upward with it. At the same time, the lower end of the engaging push shaft 44 also moves to the end where the distance between the fine-tuning wedge block 57 and the second strip-shaped sliding hole 59 is smaller. The second magnet block 58 generates a magnetic attraction force on the fine-tuning wedge block 57, ensuring that the inclined edge of the fine-tuning wedge block 57 always adheres to the engaging push shaft 44. As the engaging push shaft 44 moves...Under magnetic attraction, the fine-tuning wedge 57 gradually retracts into the fine-tuning cavity 56 and disengages from the fine-tuning groove 85. Therefore, when the fine-tuning plate 50 moves, the set of adjusting slide rods 30 will not move accordingly. Then, the thickness detection mechanism 8 is activated, and the controller 74 controls the distance sensor 27 to detect the thickness of the base fabric. Based on the detection result, the controller 74 controls the scraping drive 75 and the glue supply drive 76 to extend to appropriate lengths. The extension of the glue supply drive 76 causes the locking plate 39 to move upwards. The upward movement of the locking plate 39, through the fine-tuning screw 53, causes the fine-tuning plate 50 and multiple sets of adjusting slide rods 30 engaged with the locking plate 39 to move upwards synchronously. During this process, the distance between the locking plate 39 and the fine-tuning plate 50 remains unchanged. The upward movement of the adjusting slide rods 30 causes the connected adjusting cylinder 35 to move upwards, adjusting... The upward movement of the slide cylinder 35 increases the length of the strip-shaped through hole 36 extending into the glue supply box 29, thus increasing the communication area between the moving part and the glue supply assembly. Consequently, the amount of glue flowing from the glue supply box 29 to the adjusting slide cylinder 35 increases, resulting in a larger glue supply. Meanwhile, the adjusting slide rod 30, which is not engaged with the locking plate 39, remains stationary. The adjusting slide cylinder 35, connected to it, is completely retracted into the adjusting slide tube 34 under the push of the sealing spring 38. The strip-shaped through hole 36 on the side wall of the adjusting slide cylinder 35 is completely blocked by the side wall of the adjusting slide tube 34. The adjusting slide cylinder 35 is not connected to the glue supply box 29 and cannot supply glue. The scraping drive 75 drives the scraping bracket 10 to move upward, and the scraping bracket 10 drives the angle adjustment mechanism 11 and the scraper 12 to move upward simultaneously, adjusting the gap between the scraper 12 and the base fabric. The thicker the base fabric, the more the scraping drive... The greater the extension length of the glue supply drive component 76, the greater the upward movement distance of the adjusting slide cylinder 35, resulting in a larger glue supply. Similarly, the greater the extension length of the scraper drive component 75, the greater the upward movement distance of the scraper bracket 10, leading to a larger gap between the scraper 12 and the base fabric, and thus a larger glue application. This ensures that the gap between the scraper and the base fabric matches the glue application amount. Then, the tilt angle of the scraper 12 is adjusted as required, controlling the extension of the electric push rod 73. The extension of the electric push rod 73 drives the first sliding shaft 71 and the second sliding shaft 72 to slide along the first sliding hole 68 and the second sliding hole 69 respectively via the push plate 83. This allows the scraper 12 to rotate around its bottom end to adjust the angle. The tilt angle sensor 77 detects the tilt angle of the scraper 12 in real time and sends it to the controller 74. The controller 74 controls the fine-tuning plate 50 to move downwards based on the detection result of the tilt sensor 77. The controller 74 controls the fine-tuning motor 78 to drive the worm gear 51 to rotate. The worm gear 51 drives the fine-tuning screw 53 to rotate through the worm wheel 52. The fine-tuning screw 53 drives the fine-tuning plate 50 to move downwards through the fine-tuning screw seat 54. At this time, the height of the locking plate 39 relative to the glue supply box 29 remains fixed, so the upper slide rod 48 remains stationary. The downward movement of the fine-tuning plate 50 drives the lower slide rod 49, which is locked with it, to move downwards. The lower slide rod 49 drives the adjusting slide rod 30 connected to it to move downwards and retract into the adjusting slide tube 34. This reduces the length of the connection between the strip-shaped through hole 36 and the glue supply box 29, reduces the connection area between the moving part and the glue supply assembly, and reduces the glue supply amount. The displacement sensor 79 detects the moving distance of the fine-tuning plate 50 in real time.When the fine-tuning plate 50 moves down to a suitable distance, the controller 74 controls the fine-tuning motor 78 to stop working, completing the fine-tuning of the glue supply. The greater the downward rotation angle of the scraper 12, the greater the downward movement distance of the fine-tuning plate 50. The greater the downward movement distance of the adjusting slide cylinder 35, the smaller the glue supply. The worm gear 51, worm wheel 52, and fine-tuning screw 53 drive the fine-tuning plate 50 to move slightly, realizing the fine-tuning of the glue supply. After the angle, gap, and glue supply of the scraper 12 are adjusted, the first and second transmission motors are started simultaneously, and the switch motor 64 is controlled to drive the swing shaft 61 to rotate. The swing shaft 61 drives the arc-shaped baffle 63 to rotate away from the bottom of the adjusting slide tube 34 via the swing plate 62. At this time, the glue in the glue storage tank 28 flows into the glue supply box 29 through the glue supply channel 33, and is coated onto the surface of the base fabric through the strip-shaped through hole 36 and the adjusting slide tube 35. Then, it is evenly coated by the scraper 12. The first transmission motor drives the fixed roller 81 to rotate, thereby driving the artificial turf base fabric to be conveyed. At the same time, the second transmission motor drives the conveyor belt 82 to work, and the conveyor belt 82 also drives the artificial turf base fabric to be conveyed. The conveying speed of the fixed roller 81 and the conveying speed of the conveyor belt 82 are kept the same.
