Description

Technical Field

[0001] This utility model relates to the field of artificial turf processing technology, specifically to a hot melt adhesive roller coating device for the underside and back of artificial turf. Background Technology

[0002] Artificial turf is classified into injection-molded artificial turf and woven artificial turf according to its production process. Injection-molded artificial turf uses an injection molding process, in which plastic granules are extruded into a mold in one step, and then the turf is bent using a bending technique to ensure that the grass blades are arranged evenly and in a regular pattern, with a completely uniform blade height. It is suitable for kindergartens, sports fields, balconies, landscaping, and sandblasting, among other applications.

[0003] After the artificial turf is woven and formed into a substrate, it needs to be bonded together with the artificial grass fibers and the backing through a backing adhesive shaping process. This process also shapes the soft artificial turf to ensure its formation and reduce dimensional changes caused by thermal expansion and contraction. This requires the use of hot melt adhesive roller coating equipment.

[0004] However, in the use of existing devices, the grass fibers are prone to positional shifts during transmission, which leads to misalignment between the grass fibers and the backing fabric, making it impossible to guarantee the processing effect on the lawn; at the same time, the glue in the roller box will decrease over time, and if it is not replenished in time, it will affect the coating effect, making it less practical.

[0010] Preferably, the limiting mechanism includes a first upright frame, which is located inside the first support plate and the frame. A fixed shaft is rotatably fixed to the inner side of the lower end of the first upright frame. A limiting roller is fixedly sleeved on the outside of the fixed shaft. Limiting rings are slidably installed on both sides of the limiting roller. A fixed plate is fixedly installed on the upper side of the limiting ring. A bidirectional lead screw is rotatably installed on the inner side of the upper end of the first upright frame. A second motor is fixedly installed on the upper front end of the first upright frame.

[0011] Preferably, the middle part of the fixing plate is threaded to both sides of the bidirectional lead screw, and the top end of the bidirectional lead screw is driven to the output end of the second motor.

[0012] Preferably, a motor is fixedly installed at the front end of each of the support plates 1, 2, and 3; a hydraulic cylinder is fixedly installed at the upper end of the frame; a crossbeam is fixedly installed at the lower end of the output rod of the hydraulic cylinder; a pressure roller is rotatably installed on the inner side of the lower end of the frame; and a guide roller is rotatably installed on the inner side of the crossbeam.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a hot melt adhesive roller coating device for artificial turf backing. Through a limiting mechanism, a rotating bidirectional screw can drive the threaded fixing plates on both sides to move closer or further away, which can drive the limiting rings on both sides to move synchronously on the limiting roller. This allows adjustment of the distance between the two sets of limiting rings to meet the limiting function of grass fibers of different sizes, making it less likely to deviate during the guiding and conveying process, thereby ensuring the adhesion between the grass fibers and the backing fabric and guaranteeing the processing effect of the turf.

[0017] This utility model provides a hot melt adhesive roller coating device for artificial turf backing. The roller mechanism, driven by a motor, rotates counter-clockwise. The lower end of the roller is positioned inside the coating tank, ensuring its surface is covered with adhesive. This adhesive is then applied to the backing fabric. Through the cooperation of a movable plate and spring, the roller automatically moves upwards as the adhesive in the coating tank decreases, ensuring the roller remains consistently wetted and unaffected by reduced adhesive levels. An upward-moving connecting rod activates a pressure sensor on a limit bar, triggering an alarm from the external controller. This allows the user to promptly add adhesive to the coating tank, preventing disruption to the roller coating process. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5As shown, this utility model provides a hot melt adhesive roller coating equipment for the backing of artificial turf, including a support plate 1, a conveying roller 2 rotatably mounted on the inner side of the support plate, a guide roller 3 rotatably mounted on one side of the support plate 1, a limiting mechanism 4 at one end of the support plate 1, a frame 5 on the right side of the limiting mechanism 4, a roller coating mechanism 6 on the right side of the frame 5, a support plate 4 15 on the right side of the roller coating mechanism 6, a guide roller 3 16 rotatably mounted on the inner side of the support plate 4 15, a support plate 2 7 on the right side of the support plate 4 15, a conveying roller 2 8 rotatably mounted on the inner side of the support plate 2 7, a support plate 3 9 on the right side of the support plate 2 7, and a take-up roller 10 rotatably mounted on the inner side of the support plate 3 9.

[0026] Motor 17 is fixedly installed at the front end of support plate 1, support plate 7, and support plate 3 9. Hydraulic cylinder 11 is fixedly installed at the upper end of frame 5. Horizontal frame 12 is fixedly installed at the lower end of the output rod of hydraulic cylinder 11. Pressure roller 13 is rotatably installed on the inner side of the lower end of frame 5. Guide roller 2 14 is rotatably installed on the inner side of horizontal frame 12.

[0027] The motor 17 installed on support plate 1, support plate 2 7, and support plate 3 9 is respectively connected to the front end of conveyor roller 2, conveyor roller 2 8, and winding roller 10.

[0028] The lower ends of support plate 1, upright frame 41, machine frame 5, upright frame 2 61, support plate 4 15, support plate 2 7, and support plate 3 9 are all fixedly installed to the upper end of the base.

[0029] In this scheme, the straw fibers can be guided onto the limiting roller 43 by the guide roller 3. The conveying roller 2 rotates clockwise to facilitate the conveying of the straw fibers, allowing them to pass through the limiting roller 43 and overlap onto the guide roller 2 14 and guide roller 3 16 for conveying. The conveying roller 2 8 rotates counterclockwise to allow the base fabric to pass between the glue roller 610 and the pressure roller 2 62 and overlap onto the guide roller 2 14, thus performing the bonding work between the straw fibers and the base fabric. The height of the frame 5 can be adjusted by the hydraulic cylinder 11, thereby adjusting the distance between the pressure roller 1 13 and the guide roller 2 14, so that the pressure roller 1 13 can effectively squeeze the straw fibers and the base fabric.

[0030] like Figure 5As shown, the glue-rolling mechanism 6 includes a second upright 61, which is located inside the frame 5 and the fourth support plate 15. A pressure roller 62 is rotatably installed on the inner side of the upper end of the second upright 61. A glue-applying box 63 is fixedly installed on the inner side of the lower end of the second upright 61. A movable plate 64 is slidably installed inside the glue-applying box 63. A connecting rod 65 is slidably connected to the middle of the lower end of the glue-applying box 63. A spring 66 is sleeved on the outer side of the upper end of the connecting rod 65. A limiting crossbar 67 is fixedly installed at the lower end of the connecting rod 65. A pressure sensor 68 is fixedly installed on one side of the lower end of the glue-applying box 63. An injection pipe 69 is fixedly installed on the lower front end of the second upright 61. A glue-rolling roller 610 is rotatably installed on the inner side of the top end of the glue-applying box 63. A motor 611 is fixedly installed on the upper front end of the second upright 61.

[0031] The glue-applying box 63 is trapezoidal in shape. The lower side of the glue roller 610 is located inside the glue-applying box 63. The top of the glue roller 610 is connected to the output end of the motor 611. The bottom end of the injection pipe 69 is fixedly connected to the front end of the glue-applying box 63 and they are interconnected.

[0032] A sealing ring is fitted at the connection between the connecting rod 65 and the glue-applying box 63. The upper end of the connecting rod 65 is fixedly connected to the lower end of the movable plate 64. The two ends of the spring 66 are fixedly connected to the opposite surfaces of the movable plate 64 and the glue-applying box 63, respectively. The pressure sensor 68 is electrically connected to the external alarm.

[0033] In this solution, the limiting roller 43 can rotate freely to form a guide channel for grass fiber conveying. The limiting ring 44 constrains the grass fiber from both sides, firmly confining it within the preset conveying path. This effectively prevents the grass fiber from shifting laterally during conveying. The limiting mechanism ensures reliable bonding between the grass fiber and the backing fabric, ensuring that the grass fiber can be bonded to the backing fabric in the correct position and posture, thereby improving the overall quality of the turf product.

[0034] like Figure 4 As shown, the limiting mechanism 4 includes a first upright 41, which is located inside the support plate 1 and the frame 5. A fixed shaft 42 is rotatably fixed on the inner side of the lower end of the first upright 41. A limiting roller 43 is fixedly sleeved on the outside of the fixed shaft 42. Limiting rings 44 are slidably installed on both sides of the limiting roller 43. A fixed plate 45 is fixedly installed on the upper side of the limiting ring 44. A bidirectional lead screw 46 is rotatably installed on the inner side of the upper end of the first upright 41. A second motor 47 is fixedly installed on the upper front end of the first upright 41.

[0035] The middle part of the fixing plate 45 is threaded to both sides of the double-acting lead screw 46, and the top of the double-acting lead screw 46 is driven to the output end of the motor 47.

[0036] In this design, as the amount of glue in the glue application tank 63 decreases, the spring 66 gradually returns to its original position, which in turn pushes the movable plate 64 upward. As the movable plate 64 moves upward, it continuously pushes the glue above it upward, ensuring that the glue continuously wets the glue roller 610. When the glue in the glue application tank 63 is used up, the connecting rod 65 will drive the limit bar 67 to gradually rise, causing the limit bar 67 to contact the pressure sensor 68. The pressure sensor 68 can then transmit a signal to the external alarm, which will alert the staff to the glue usage in the glue application tank 63, allowing the staff to add glue to the tank in a timely manner through the injection pipe 69.

[0037] The working principle of this artificial turf underlay hot melt adhesive roller coating equipment will be explained in detail below.

[0038] like Figures 1-5 As shown, in use, the artificial turf backing hot melt adhesive roller coating equipment works by winding grass fibers around conveyor roller 2 and backing fabric around conveyor roller 8. One end of the finished product is wound onto take-up roller 10. During the adhesive coating process, motors 17 on support plates 1, 7, and 9 are started, which in turn drive conveyor roller 2, conveyor roller 8, and take-up roller 10 to rotate. This allows conveyor roller 2 to transport the grass fibers. The second feeding roller 8 conveys the base fabric, while the take-up roller 10 takes up the glued finished product. During the conveying of the straw and base fabric, the third motor 611 can be started, driving the glue-rolling roller 610 to rotate counterclockwise. The lower end of the glue-rolling roller 610 is placed inside the glue-applying box 63, ensuring its roller surface is fully in contact with the glue inside. The glue adheres evenly to the surface of the glue-rolling roller 610. When the base fabric is conveyed between the glue-rolling roller 610 and the second pressure roller 62, the rotating glue-rolling roller 610... 10. Apply glue evenly to the base fabric to achieve precise glue application. The glued bottom and grass fibers can then be fully pressed together between guide roller 3 and pressure roller 13 to form a finished product, thus completing the artificial turf backing coating process. By starting motor 2 47, motor 2 47 can drive the bidirectional lead screw 46 to rotate. Since the threads on both sides rotate in opposite directions, the two fixing plates 45 installed on the bidirectional lead screw 46 will move closer or further away according to the rotation direction of motor 2 47. This can drive the limiting ring 44 to slide synchronously on the limiting roller 43, thereby adjusting the distance between the two sets of limiting rings 44. When the grass fibers are guided and conveyed on the limiting roller 43, the limiting rings 44 constrain the grass fibers from both sides, firmly limiting the grass fibers within the preset conveying path, effectively preventing the grass fibers from shifting laterally during the conveying process. This ensures that the grass fibers can be bonded to the base fabric in the correct position and posture, thereby improving the overall quality of the turf product.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
