[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] A hot melt adhesive wrapping machine for cladding, combined with Figures 1 to 4 As shown, the machine includes a frame 1, with protective mechanisms 3 erected on opposite sides along its width. The frame 1 also includes a conveying mechanism 2, a cleaning mechanism, an unwinding mechanism 5, a gluing mechanism 4, a flattening roller, and a cutting mechanism 6. These mechanisms are located above the conveying mechanism 2. The conveying mechanism 2 is positioned between the two protective mechanisms 3 and along the length of the frame 1. The conveying mechanism 2 is used for horizontally conveying the sheathing plate; the cleaning mechanism is used to clean the sheathing plate; the unwinding mechanism 5 is used to unwind the sheathing material; the gluing mechanism 4 is used to apply glue to the unwound sheathing material; the flattening roller is used to flatten the glued sheathing material onto the sheathing plate; and the cutting mechanism 6 is used to cut the sheathing material after it has been wrapped around the sheathing plate. Furthermore, the cleaning mechanism, the gluing mechanism 4, the unwinding mechanism 5, and the cutting mechanism 6 are arranged sequentially along the conveying direction of the conveying mechanism 2. The flattening roller is rotated and longitudinally adjustable and is located behind the discharge end of the gluing mechanism 4. By longitudinally adjusting the flattening roller, the covering material of different thicknesses can be flattened. The cutting direction of the cutting mechanism 6 is set at an angle to the conveying direction of the conveying mechanism 2, thereby achieving straight cutting of the covering material.

[0035] The protective mechanism 3 is used to protect the sleeve plate and prevent it from falling. Specifically, the protective mechanism 3 includes a number of uprights 31 that are spaced apart along the length of the frame 1. The uprights 31 on one side of the protective mechanism 3 located between the glue application mechanism 4 and the cutting mechanism 6 can be moved away from or closer to the other side of the protective mechanism 3 by means of the limiting translation component 32 set on the frame 1.

[0036] The limiting and translational assembly 32 includes two spaced and rotatably mounted plate limiting screws 321 on the frame 1 along its length. A movable seat 322 is threaded onto each of the two plate limiting screws 321. The movable seat 322 is positioned along the length of the frame 1. A vertical rod 31 located between the gluing mechanism 4 and the cutting mechanism 6 is mounted on the movable seat 322. The ends of the two plate limiting screws 321 are connected via a limiting transmission assembly. One end of one plate limiting screw 321 is connected to a limiting drive motor. When the limiting drive motor drives the connected plate limiting screw 321 to rotate, the two plate limiting screws 321 rotate synchronously, thereby moving the vertical rod 31 on the movable seat 322 away from or closer to the other vertical rod 31, thus limiting the transmission of the plate. Furthermore, by adjusting the limiting drive motor, it can be adapted to limit plate widths.

[0037] The conveying mechanism 2 includes several rotating shafts 21 spaced apart and rotatably mounted on the frame 1 along its length. Each rotating shaft 21 is positioned along the width of the frame 1 and has several drive wheels 22 spaced apart along its length. The drive wheels 22 carry the sleeve plates. The shafts 21 are connected at opposite ends via a conveying transmission assembly, and one end of each shaft 21 is connected to a conveying drive motor. When the conveying drive motor drives the connected shaft 21 to rotate, the shaft 21 rotates synchronously via the conveying transmission assembly, thereby driving the drive wheels 22 to rotate. The rotation of the drive wheels 22 conveys the sleeve plates. During conveying, the sleeve plates are placed on the drive wheels 22 one at a time, facilitating the cutting mechanism 6 to cut the covering material from the gap between the sleeve plates.

[0038] like Figure 12 As shown, the cleaning mechanism includes a cleaning gantry 7 spanning the width of the frame 1 above the frame 1. A rotating drum 8 is rotatably mounted on the cleaning gantry 7 above the conveying mechanism 2. Brushes 9 are circumferentially arranged on the side wall of the rotating drum 8. One end of the rotating drum 8 is connected to a cleaning drive motor 10 mounted on the cleaning gantry 7. When the cleaning drive motor 10 drives the rotating drum 8 to rotate, the brushes 9 on the rotating drum 8 rotate, thereby cleaning the conveyed plates. At the same time, a dust suction fan 11 is also installed on the cleaning gantry 7, and the dust raised during the cleaning process is sucked away by the dust suction fan 11.

[0039] like Figures 5 to 6 As shown, the unwinding mechanism 5 includes an unwinding gantry 51 erected on the frame 1 and located on one side of the conveying mechanism 2. Two guide rails 52 are horizontally and spaced apart along the conveying direction of the conveying mechanism 2 on the unwinding gantry 51. The guide rails 52 are perpendicular to the conveying mechanism 2. An inverted T-shaped slide block 53 is slidably mounted on the guide rail 52, and the inverted T-shaped slide block 53 is adjustablely mounted to the guide rail 52 by bolts. A drive roller 54 is horizontally rotatably mounted on an inverted T-shaped slide 53. The drive roller 54 is perpendicular to the conveying mechanism 2. An unwinding drive motor 55 is connected to the connection end between the drive roller 54 and the inverted T-shaped slide 53. The unwinding drive motor 55 is mounted on the inverted T-shaped slide 53 and drives the drive roller 54 to rotate. A roll of wrapping material is fitted onto the drive roller 54 furthest from the gluing mechanism 4. An unwinding guide roller 56 is positioned between the two drive rollers 54 and is horizontally rotatably mounted on the unwinding gantry 51. The unwinding guide roller 56 and the two drive rollers 54 are arranged in a triangle. In use, the position of the drive roller 54 relative to the conveying mechanism 2 can be adjusted by adjusting the installation position of the inverted T-shaped slide 53. The roll of wrapping material is mounted on the drive roller 54 furthest from the gluing mechanism 4. One end of the wrapping material passes around the unwinding guide roller 56 and then around the other drive roller 54. Unwinding is achieved by driving the drive roller 54 to rotate through the unwinding drive motor 55.

[0040] like Figures 5 to 8 As shown, the gluing mechanism 4 includes a gluing gantry 41 spanning the frame 1. A gluing translation component 42, which moves along the width of the frame 1, is mounted on the gluing gantry 41. Two side plates 43 are erected on the gluing translation component 42, and the two side plates 43 are arranged opposite each other along the width of the frame 1. A feed guide roller 47, a sheathing material limiting component 46, a gluing component 44, and a scraping component 45 are arranged between the side plates 43. The feed guide roller 47 guides the sheathing material conveyed by the unwinding mechanism 5, thereby enabling the sheathing material to be fed into the gluing component 44 and the scraping component 45. The sheathing material limiting component 46 limits the sheathing material, ensuring accurate conveying. The gluing component 44 applies glue to the sheathing material. The scraping component 45 scrapes the glued sheathing material, ensuring the glue is evenly applied to the sheathing material and removing excess glue.

[0041] The glue-applying translation assembly 42 includes two glue-applying translation slide rails 421 and a glue-applying translation screw mounted on the glue-applying gantry 41. The two glue-applying translation slide rails 421 are horizontally spaced along the length of the frame 1 and are perpendicular to the conveying direction of the conveying mechanism 2. The glue-applying translation screw is parallel to the glue-applying translation slide rails 421 and is located between the two glue-applying translation slide rails 421 and is rotatably connected to the glue-applying gantry 41. A glue-applying translation plate 422 is threadedly connected to the glue-applying translation slide rails 421 and is slidably assembled with them. One end of the glue-applying translation screw is connected to a handwheel. The glue-applying translation screw is rotated by driving the handwheel, thereby realizing the horizontal movement of the glue-applying translation plate 422. Furthermore, the feeding guide roller 47, the covering material limiting component 46, the glue application component 44, and the glue scraping component 45 are all mounted on the glue application translation plate 422 via the side plate 43. Thus, by moving the glue application translation plate 422 horizontally, the feeding guide roller 47, the covering material limiting component 46, the glue application component 44, and the glue scraping component 45 can be moved as a whole to adjust the position of the glue application mechanism 4 relative to the covering material, thereby applying glue to different covering materials more accurately.

[0042] There are three feed guide rollers 47, which are arranged in a triangle and located above the coating assembly 44, rotatably connected to the side plate 43. The sheathing material passing through the unwinding mechanism 5 passes through the three feed guide rollers 47 in sequence and enters the coating assembly 44.

[0043] The covering material limiting assembly 46 is located in front of the feed guide roller 47. The covering material limiting assembly 46 includes a covering material limiting screw 461 and a limiting guide rail 462 horizontally disposed between the two side plates 43. Both ends of the covering material limiting screw 461 are rotatably connected to the side plates 43. A translation seat 463, which is slidably assembled with the limiting guide rail 462, is threaded onto the covering material limiting screw 461. A support rod 464 is erected on the translation seat 463, and a stop block 465 is adjustablely disposed on the support rod 464. The stop block 465 is used to block the covering material on one side of the feed guide roller 47, thereby limiting the covering material. One end of the covering material limiting screw 461 is connected to a covering material limiting motor 466, which is disposed on the side plate 43. The foreskin material limiting motor 466 drives the foreskin material limiting screw 461 to rotate, thereby driving the support rod 464 to move linearly along the foreskin material limiting screw 461, thereby enabling the stop block 465 on the support rod 464 to move away from and closer to the foreskin material from one side, thus achieving the limiting of foreskin materials of different widths.

[0044] The glue application assembly 44 is positioned below the feed guide roller 47 and the covering material limiting assembly 46. The glue application assembly 44 includes a glue tank 441, which is mounted on the glue application translation assembly 42 and located between the two side plates 43. The glue tank 441 is connected to several adjustable multi-joint tubes 442. Each multi-joint tube 442 has a glue nozzle 443 at its outlet. The position of the glue nozzle 443 can be adjusted via the multi-joint tubes 442, thereby enabling glue application to covering materials of different widths. The glue tank 441 is also connected to a glue pusher assembly, which pushes the glue, allowing the glue to be sprayed out from the glue nozzle 443 through the multi-joint tubes 442.

[0045] Specifically, the glue-pushing assembly includes a piston that is sealed and slidably assembled in a glue tank 441. A push rod 449, extending horizontally from the glue tank 441 and slidably assembled in a sealed manner with the glue tank 441, is connected to one side of the piston. A side frame 444, located away from the side plate 43, is supported on a side plate 43 near the push rod 449. A glue-pushing guide rail 448 and a glue-pushing screw 446 are horizontally arranged between the side frame 444 and its adjacent side plate 43. The glue-pushing screw 446 is parallel to the glue-pushing guide rail 448 and rotatably connected to the side frame 444 and the side plate 43. The glue-pushing screw 446 is also threadedly connected to a glue-pushing slide 447 that is slidably assembled with the glue-pushing guide rail 448. The glue-pushing slide 447 is also fixedly connected to the outer end of the push rod 449. The outer end of the glue-pushing screw 446 is connected to a glue-pushing drive motor 445 via a glue-pushing transmission assembly. The glue-pushing drive motor 445 is mounted on the side frame 444. When the glue-pushing drive motor 445 rotates, the glue-pushing screw 446 rotates. The rotation of the glue-pushing screw 446 drives the piston connected to the push rod 449 to squeeze the glue tank 441 in the glue tank 441, thereby realizing the glue material being sprayed out from the glue nozzle 443 through the multi-section tube 442.

[0046] The glue-scraping assembly 45 includes two horizontally telescopic cylinders 451 arranged opposite each other and horizontally mounted on the two side plates 43. The telescopic rods of the horizontal telescopic cylinders 451 are arranged in the conveying direction of the conveying mechanism 2 and connected to mounting supports 452 that are slidably assembled with the side plates 43. Two vertically arranged glue-scraping discharge guide rollers 453 are rotatably arranged between the two mounting supports 452. The glue-scraping discharge guide rollers 453 are located below and in front of the glue-applying assembly 44. The coating material coming out from the feed guide roller 47 passes in front of the glue nozzle 443 and then passes around the glue-scraping discharge guide roller 453 on the side close to the glue-applying assembly 44. At the same time, a flattening roller is rotatably arranged below and behind the glue-scraping discharge guide roller 453. The coating material passes around the glue-scraping discharge guide roller 453 and enters below the flattening roller. A scraper 454 is arranged in front of the glue-scraping discharge guide roller 453. The scraper 454 is located between the two side plates 43 and below the glue-applying assembly 44. In use, the distance between the glue-discharging guide roller 453 and the scraper 454 is adjusted by extending and retracting the horizontal telescopic cylinder 451 according to the thickness of the forging material. This adjusts the distance between the forging material and the scraper 454. As the forging material is conveyed, the scraper 454 scrapes the glue on the forging material evenly and removes excess glue, thus preventing defects such as wrinkles and bubbles from occurring during the later forging process. A glue-receiving box 455 is provided below the scraper 454 to catch the glue scraped off by the scraper 454.

[0047] In order to achieve rapid drying of the rubber compound after the sheathing material is wrapped around the liner, a drying fan is provided at intervals on the side protection mechanism 3 located between the rear of the first flattening roller and the front of the cutting mechanism 6.

[0048] like Figures 9 to 11As shown, the cutting mechanism 6 includes a support plate 61 detachably mounted on the protective mechanism 3. A horizontally mounted electric guide rail 62 is mounted on the support plate 61. The sliding direction of the slider on the electric guide rail 62 forms an angle with the conveying direction of the conveying mechanism 2. The angle between the sliding direction of the slider on the electric guide rail 62 and the conveying direction of the conveying mechanism 2 can be adjusted by adjusting the installation position of the support plate 61; specifically, the angle is an obtuse angle. A mounting base 63 is mounted on the slider of the electric guide rail 62. A vertical telescopic cylinder 64 is longitudinally mounted on the mounting base 63. The telescopic rod of the vertical telescopic cylinder 64 is downwardly positioned and connected to an inverted L-shaped mounting plate 65. A horizontally mounted cutting drive motor 66 is mounted on the inverted L-shaped mounting plate 65. A circular cutting blade 67 is connected to the rotating shaft of the cutting drive motor 66. The circular cutting blade 67 moves under the drive of the electric guide rail 62, and its cutting direction forms an obtuse angle with the conveying direction of the conveying mechanism 2. When the cutting drive motor 66 drives the circular cutting blade 67 to rotate, the circular cutting blade 67 can perform cutting action. At the same time, the electric guide rail 62 drives the inverted L-shaped mounting plate 65 to move the cutting drive motor 66 and the circular cutting blade 67 along the electric guide rail 62, thereby realizing the cutting of the covering material between the sleeve plates conveyed by the conveying mechanism 2. Under the condition that the cutting direction is set at an obtuse angle to the conveying direction, the cutting surface is straight rather than oblique, realizing one-time cutting and forming without subsequent manual correction. At the same time, the cutting drive motor 66 and the circular cutting blade 67 can be adjusted longitudinally by the vertical telescopic cylinder 64, thereby adapting to the cutting of covering materials of different thickness sleeve plates.

[0049] A protective cover 68 is fitted onto the circular cutting blade 67. The protective cover 68 is set on the L-shaped mounting plate 65 and exposes the bottom end of the circular cutting blade 67, ensuring that the cutting action of the circular cutting blade 67 is not affected.

[0050] The coating machine also includes a PLC controller, which is located on one side of the frame 1. The output of the PLC controller is connected to the controlled ends of the cleaning mechanism, conveying mechanism 2, gluing mechanism 4, unwinding mechanism 5 and cutting mechanism 6 respectively. Specifically, it is connected to the controlled ends of the dust suction fan 11, cleaning drive motor 10, conveying drive motor, limit drive motor, unwinding drive motor 55, coating material limit motor 466, glue pushing drive motor 445, horizontal telescopic cylinder 451, drying fan, electric guide rail 62 and cutting drive motor 66 respectively, thereby realizing the automatic control of the coating machine and completing the coating and cutting of the sizing plate.

[0051] In use, the PLC controller automatically operates each mechanism to complete the plate wrapping and cutting. The working process is as follows:

[0052] Plate conveying and protection: Start the conveying drive motor, which drives the rotating shaft 21 of the conveying mechanism 2 to rotate through the conveying transmission assembly, causing the transmission wheel 22 to rotate. The plates are placed horizontally on the transmission wheel 22 one at a time for horizontal conveying. The uprights 31 of the protection mechanism 3 adjust the spacing through the limiting and translational assembly 32 to protect and limit the plates, adapting to plates of different widths.

[0053] Unwinding and gluing of the outer material: The unwinding drive motor 55 of the unwinding mechanism 5 drives the drive roller 54 to rotate, unwinding the outer material into the gluing mechanism 4; the gluing mechanism 4 adjusts its position through the gluing translation component 42, guides the material with the feed guide roller 47, limits the outer material with the outer material limiting component 46, applies the glue with the gluing component 44, and scrapes the glue with the scraping component 45 to make the glue even and scrape off the excess glue.

[0054] Covering and flattening of the outer material: After the outer material is coated with glue, it is flattened onto the sleeve plate by the flattening roller. The flattening roller can be adjusted longitudinally to adapt to sleeve plates of different thicknesses.

[0055] Cutting and drying: The drying fan quickly dries the coated material; the electric guide rail 62 and the cutting drive motor 66 of the cutting mechanism 6 work together to enable the circular cutting blade 67 to cut the coating material between the two sleeves at an angle to the conveying direction, achieving a straight cut. The cutting drive motor 66 and the circular cutting blade 67 can be longitudinally adjusted by the vertical telescopic cylinder 64 to adapt to sleeves of different thicknesses.
