[0020] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0021] A hot - melt glue coating machine for sheathing a sleeve board, combined with Figures 1 to 4As shown, it includes a frame 1, on which protective mechanisms 3 are erected on opposite sides along the width direction of the frame 1. The frame 1 is also provided with a conveying mechanism 2, a cleaning mechanism, an unwinding mechanism 5, a gluing mechanism 4, a flattening roller and a cutting mechanism 6, and the cleaning mechanism, the unwinding mechanism 5, the gluing mechanism 4, the flattening roller and the cutting mechanism 6 are respectively located above the conveying mechanism 2, wherein the conveying mechanism 2 is located between the protective mechanisms 3 on both sides and is arranged along the length direction of the frame 1, the conveying mechanism 2 is used for horizontally conveying the sleeve; the cleaning mechanism is used for cleaning the sleeve; the unwinding mechanism 5 is used for unwinding the foreskin material; the gluing mechanism 4 is used for gluing the unwound foreskin material; the flattening roller is used for flattening the glued foreskin material on the sleeve; the cutting mechanism 6 is used for cutting the foreskin material after it is covered on the sleeve. The cleaning mechanism, the gluing mechanism 4, the unwinding mechanism 5 and the cutting mechanism 6 are arranged in sequence along the conveying direction of the conveying mechanism 2. The flattening roller is rotatable and longitudinally adjustable behind the discharge end of the gluing mechanism 4. By longitudinally adjusting the flattening roller, the foreskin material of the sleeves 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, so that the foreskin material can be cut straightly.

[0022] The protective mechanism 3 is used to protect the sleeve plate and prevent it from falling. Specifically, the protective mechanism 3 includes a plurality of vertical rods 31 arranged at intervals along the length direction of the frame 1. The vertical rod 31 located between the gluing mechanism 4 and the cutting mechanism 6 on one side of the protective mechanism 3 can be moved away from and close to the protective mechanism 3 on the other side through a limit translation assembly 32 arranged on the frame 1.

[0023] The limit translation assembly 32 includes two sleeve plate limit screw rods 321 which are spaced apart along the length direction of the frame 1 and are rotatably arranged on the frame 1. A moving seat 322 is threadedly connected to the two sleeve plate limit screw rods 321. The moving seat 322 is arranged along the length direction of the frame 1. The vertical rod 31 located between the gluing mechanism 4 and the cutting mechanism 6 is arranged on the moving seat 322. The same side ends of the two sleeve plate limit screw rods 321 are connected by a limit transmission assembly. One end of a sleeve plate limit screw rod 321 is connected to a limit drive motor. When the limit drive motor drives the sleeve plate limit screw rod 321 to rotate, the two sleeve plate limit screw rods 321 rotate synchronously, so that the vertical rod 31 on the moving seat 322 moves away from and close to the vertical rod 31 on the other side, thereby realizing the limit of sleeve plate transmission, and through the adjustment of the limit drive motor, it can be applied to sleeve plate limit of different widths.

[0024] The conveying mechanism 2 includes a plurality of rotating shafts 21 which are spaced apart along the length direction of the frame 1 and are rotatably arranged on the frame 1. The rotating shafts 21 are arranged along the width direction of the frame 1 and a plurality of transmission wheels 22 are spaced apart along the length direction of the rotating shafts 21. The transmission wheels 22 are used to carry the sleeves. The same side ends of the rotating shafts 21 are connected by a transmission transmission assembly, and one end of a rotating shaft 21 is connected to a conveying drive motor. When the transmission drive motor drives the connected rotating shaft 21 to rotate, the rotating shaft 21 rotates synchronously through the transmission transmission assembly, thereby driving the transmission wheel 22 to rotate. The transmission wheel 22 rotates to realize the conveying of the sleeves on the transmission wheel 22. When the sleeves are conveyed, the sleeves are placed one by one on the transmission wheel 22, so that it is convenient for the cutting mechanism 6 to cut the foreskin material from the interval area between the two sleeves.

[0025] like Figure 12 As shown, the cleaning mechanism includes a cleaning gantry 7 arranged above the frame 1 along the width direction of the frame 1, a rotating drum 8 located above the conveying mechanism 2 is rotatably arranged on the cleaning gantry 7, a brush 9 is circumferentially arranged on the side wall of the rotating drum 8, and one end of the rotating drum 8 is connected to a cleaning drive motor 10 arranged on the cleaning gantry 7. When the cleaning drive motor 10 drives the rotating drum 8 to rotate, the brush 9 on the rotating drum 8 rotates, thereby cleaning the conveyed sleeve. At the same time, a dust suction fan 11 is also arranged on the cleaning gantry 7, and the dust raised during the cleaning process is sucked away by the dust suction fan 11.

[0026] like Figures 5 to 6 As shown, the unwinding mechanism 5 includes an unwinding gantry 51 which is erected on the frame 1 and located on one side of the conveying mechanism 2. Two guide rails 52 are horizontally and spaced apart on the unwinding gantry 51 along the conveying direction of the conveying mechanism 2. The guide rails 52 are arranged perpendicular to the conveying mechanism 2. An inverted T-shaped slide 53 is slidably mounted on the guide rail 52, and the inverted T-shaped slide 53 can be adjustably assembled with the guide rail 52 by means of penetrated bolts. An active roller 54 is horizontally rotatably arranged on the inverted T-shaped slide 53, and the active roller 54 is arranged perpendicular to the conveying mechanism 2. An unwinding drive motor 55 is connected to the connecting end of the active roller 54 and the inverted T-shaped slide 53, and the unwinding drive motor 55 is arranged on the inverted T-shaped slide 53. The unwinding drive motor 55 is used to drive the active roller 54 to rotate, and a foreskin material roll is sleeved on the active roller 54 away from the gluing mechanism 4, and an unwinding guide roller 56 is arranged between the two active rollers 54. The unwinding guide roller 56 is horizontally rotatably arranged on the unwinding gantry 51, and the unwinding guide roller 56 and the two active rollers 54 are arranged in a triangle. When in use, the position of the active roller 54 relative to the conveying mechanism 2 can be adjusted by adjusting the installation position of the inverted T-shaped slide 53, and the foreskin material roll is installed on the active roller 54 away from the gluing mechanism 4. One end of the foreskin material passes around the unwinding guide roller 56 and then around another active roller 54, and the unwinding is achieved by driving the active roller 54 to rotate through the unwinding drive motor 55.

[0027] likeFigures 5 to 8 As shown, the glue - applying mechanism 4 includes a glue - applying gantry 41 straddling the frame 1. A glue - applying translation assembly 42 is arranged on the glue - applying gantry 41 and can translate in the width direction of the frame 1. Two side plates 43 are vertically arranged on the glue - applying translation assembly 42 and are oppositely arranged in the width direction of the frame 1. Between the side plates 43, there are a feeding guide roller 47, a sheathing material limiting assembly 46, a glue - applying assembly 44, and a glue - scraping assembly 45. Among them, the feeding guide roller 47 is used to guide the feeding of the sheathing material conveyed by the unwinding mechanism 5, so as to convey the sheathing material into the glue - applying assembly 44 and the glue - scraping assembly 45; the sheathing material limiting assembly 46 is used to limit the sheathing material, so as to ensure the accurate conveyance of the sheathing material; the glue - applying assembly 44 is used to apply glue to the sheathing material; the glue - scraping assembly 45 is used to scrape the glue on the sheathing material after glue - applying, so that the glue is evenly coated on the sheathing material and the excess glue is scraped off.

[0028] The glue - applying translation assembly 42 includes two glue - applying translation slide rails 421 and a glue - applying translation lead screw arranged on the glue - applying gantry 41. Among them, the two glue - applying translation slide rails 421 are horizontally and spaced apart in the length direction of the frame 1. At the same time, the glue - applying translation slide rails 421 are arranged perpendicular to the conveying direction of the conveying mechanism 2; the glue - applying translation lead screw is arranged parallel to the glue - applying translation slide rails 421 and is located between the two glue - applying translation slide rails 421 and is rotationally connected to the glue - applying gantry 41. A glue - applying translation plate 422 that is slidably assembled with the glue - applying translation slide rails 421 is threadedly connected to the glue - applying translation lead screw. One end of the glue - applying translation lead screw is connected with a handwheel. By driving the glue - applying translation lead screw to rotate through the handwheel, the horizontal movement of the glue - applying translation plate 422 is realized. And the feeding guide roller 47, the sheathing material limiting assembly 46, the glue - applying assembly 44, and the glue - scraping assembly 45 are all arranged on the glue - applying translation plate 422 through the side plates 43. Thus, through the horizontal movement of the glue - applying translation plate 422, the overall movement of the feeding guide roller 47, the sheathing material limiting assembly 46, the glue - applying assembly 44, and the glue - scraping assembly 45 is realized, so as to adjust the position of the whole glue - applying mechanism 4 relative to the sheathing material and apply glue to different sheathing materials more accurately.

[0029] There are three feeding guide rollers 47, and the three feeding guide rollers 47 are arranged in a triangle and are rotationally connected to the side plates 43 above the glue - applying assembly 44. The sheathing material passing out from the unwinding mechanism 5 bypasses the three feeding guide rollers 47 in sequence and enters the glue - applying assembly 44.

[0030] The foreskin material limiting component 46 is arranged in front of the feeding guide roller 47. The foreskin material limiting component 46 includes a foreskin material limiting screw rod 461 horizontally arranged between the two side plates 43 and a limiting guide slide rail 462. The two ends of the foreskin material limiting screw rod 461 are rotatably connected to the side plates 43. A translation seat 463 that is slidably assembled with the limiting guide slide rail 462 is threadedly connected to the foreskin material limiting screw rod 461. A support rod 464 is erected on the translation seat 463, and a stop block 465 is adjustably arranged on the support rod 464. The stop block 465 is used to block the foreskin material from one side of the foreskin material on the feeding guide roller 47, so as to realize the limitation of the foreskin material. One end of the foreskin material limiting screw rod 461 is connected with a foreskin material limiting motor 466, and the foreskin material limiting motor 466 is arranged on the side plate 43. By driving the foreskin material limiting screw rod 461 to rotate through the foreskin material limiting motor 466, the support rod 464 is driven to move linearly along the foreskin material limiting screw rod 461, and further the stop block 465 on the support rod 464 moves away from and approaches the foreskin material from one side of the foreskin material, so as to realize the limitation of foreskin materials with different widths.

[0031] The glue coating component 44 is arranged below the feeding guide roller 47 and the foreskin material limiting component 46. The glue coating component 44 includes a glue storage bin 441. The glue storage bin 441 is arranged on the glue coating translation component 42 and is located between the two side plates 43. A plurality of adjustable universal joints 442 are communicated with the glue storage bin 441. A glue spraying nozzle 443 is arranged at the discharge port of the universal joint 442. The position of the glue spraying nozzle 443 can be adjusted through the universal joint 442, so as to realize the glue coating of foreskin materials with different widths. The glue storage bin 441 is also connected with a glue pushing sub-component, and the glue pushing sub-component is used to push the glue, so as to realize the glue material being sprayed out from the glue spraying nozzle 443 through the universal joint 442.

[0032] Specifically, the glue pushing sub-component includes a piston that is hermetically and slidably assembled in the glue storage bin 441. One side of the piston is connected with a push rod 449 that horizontally passes through the glue storage bin 441 and is hermetically and slidably assembled with the glue storage bin 441. A side frame 444 that is arranged away from the side plate 43 is supported on the side plate 43 close to the push rod 449. A glue pushing guide slide rail 448 and a glue pushing screw rod 446 are horizontally arranged between the side frame 444 and its adjacent side plate 43. The glue pushing screw rod 446 is arranged in parallel with the glue pushing guide slide rail 448, and the glue pushing screw rod 446 is rotatably connected to the side frame 444 and the side plate 43. A glue pushing slide seat 447 that is slidably assembled with the glue pushing guide slide rail 448 is also threadedly connected to the glue pushing screw rod 446. The glue pushing slide seat 447 is also fixedly connected to the outer end of the push rod 449, and the outer end of the glue pushing screw rod 446 is connected with a glue pushing driving motor 445 through a glue pushing transmission component. The glue pushing driving motor 445 is arranged on the side frame 444. When the glue pushing driving motor 445 rotates, the glue pushing screw rod 446 rotates, and the rotation of the glue pushing screw rod 446 drives the piston connected to the push rod 449 to extrude the glue in the glue storage bin 441, so as to realize the glue material being sprayed out from the glue spraying nozzle 443 through the universal joint 442.

[0033] The glue scraping assembly 45 includes two horizontally telescopic cylinders 451 that are oppositely arranged and horizontally arranged on the two side plates 43 respectively. The telescopic rod of the horizontally telescopic cylinder 451 is arranged in the conveying direction of the conveying mechanism 2 and is connected with a mounting support 452 that is slidably assembled with the side plate 43. Between the two mounting supports 452, two vertically arranged glue scraping and discharging guide rollers 453 are rotatably arranged. The glue scraping and discharging guide rollers 453 are arranged directly below and in front of the glue coating assembly 44. The sheathing material coming out of the feeding guide roller 47 bypasses the front of the glue spraying nozzle 443 and then bypasses the side of the glue scraping and discharging guide roller 453 close to the glue coating assembly 44. At the same time, the flattening roller is rotatably arranged below and behind the glue scraping and discharging guide roller 453. The sheathing material enters below the flattening roller after winding out from the glue scraping and discharging guide roller 453. A scraper 454 is arranged directly in front of the glue scraping and discharging guide roller 453. The scraper 454 is arranged between the two side plates 43 and below the glue coating assembly 44. During use, according to the thickness of the sheathing material, the distance between the glue scraping and discharging guide roller 453 and the scraper 454 is adjusted by the telescopic movement of the horizontally telescopic cylinder 451, so as to adjust the distance between the sheathing material and the scraper 454. Then, as the sheathing material is conveyed, the scraper 454 scrapes the glue on the sheathing material evenly and scrapes off the excess glue, thereby avoiding defects such as wrinkles and bubbles during the subsequent sheathing process. A glue receiving box 455 is arranged below the scraper 454. The glue receiving box 455 is used to receive the glue scraped off by the scraper 454.

[0034] In order to achieve the rapid drying of the glue after the sheathing material is wrapped around the sleeve plate, drying blowers are arranged at intervals on the side protection mechanism 3 between the rear of the first flattening roller and the front of the cutting mechanism 6.

[0035] Such as Figures 9 to 11As shown in the figure, the cutting mechanism 6 includes a support plate 61 detachably arranged on the protection mechanism 3. A horizontally arranged electric guide rail 62 is provided 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. And by adjusting the installation position of the support plate 61, the angle formed by the sliding direction of the slider on the electric guide rail 62 and the conveying direction of the conveying mechanism 2 can be adjusted. Specifically, the angle is an obtuse angle. An installation seat 63 is arranged on the slider of the electric guide rail 62. A vertical telescopic cylinder 64 is longitudinally arranged on the installation seat 63. The telescopic rod of the vertical telescopic cylinder 64 is arranged downward and connected with an inverted L-shaped mounting plate 65. A horizontally arranged cutting drive motor 66 is arranged on the inverted L-shaped mounting plate 65. The rotating shaft of the cutting drive motor 66 is connected with a circular cutting knife 67. The circular cutting knife 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 knife 67 to rotate, the circular cutting knife 67 can perform a cutting action. At the same time, the electric guide rail 62 drives the inverted L-shaped mounting plate 65 to drive the cutting drive motor 66 and the circular cutting knife 67 to move along the electric guide rail 62, so as to realize the cutting of the wrapping material between the sheathing plates wrapped with the wrapping material conveyed by the conveying mechanism 2. And under the condition that the cutting direction and the conveying direction form an obtuse angle, the cutting surface is flat instead of inclined, realizing one-time cutting forming without subsequent manual correction. At the same time, the cutting drive motor 66 and the circular cutting knife 67 can be longitudinally adjusted through the vertical telescopic cylinder 64 to adapt to the cutting of the wrapping material of sheathing plates with different thicknesses.

[0036] A protective cover 68 is sleeved on the circular cutting knife 67. The protective cover 68 is arranged on the L-shaped mounting plate 65 and exposes the bottom end of the circular cutting knife 67 to ensure that it does not affect the cutting action of the circular cutting knife 67.

[0037] The wrapping machine further includes a PLC controller. The PLC controller is arranged on one side of the frame 1. The output end of the PLC controller is respectively connected with the controlled ends of the cleaning mechanism, the conveying mechanism 2, the gluing mechanism 4, the unwinding mechanism 5 and the cutting mechanism 6. Specifically, it is respectively connected with the controlled ends of the dust suction fan 11, the cleaning drive motor 10, the conveying drive motor, the limit drive motor, the unwinding drive motor 55, the wrapping material limit motor 466, the glue pushing drive motor 445, the horizontal telescopic cylinder 451, the drying fan, the electric guide rail 62 and the cutting drive motor 66, so as to realize the automatic control of the wrapping machine and complete the wrapping and cutting of the sheathing plates.

[0038] When the present invention is in use, the PLC controller controls the automatic operation of each mechanism to complete the wrapping and cutting of the sheathing plates. The working process is as follows: Template Conveyor and Protection: Start the conveyor drive motor, drive the rotating shaft 21 of the conveyor mechanism 2 through the conveyor drive assembly, rotate the drive wheel 22, and horizontally place the templates one by one at intervals on the drive wheel 22 to horizontally convey the templates; the vertical rods 31 of the protection mechanism 3 adjust the spacing through the limit translation assembly 32 to protect and limit the templates and adapt to templates of different widths.

[0039] Release and Glue Coating of the Sheathing Material: The release drive motor 55 of the release mechanism 5 drives the driving roller 54 to rotate, and the sheathing material roll is released and fed into the glue coating mechanism 4; the glue coating mechanism 4 adjusts its position through the glue coating translation assembly 42, is guided by the feed guiding roller 47, limited by the sheathing material limiting assembly 46, and the glue coating assembly 44 applies glue, and the glue scraping assembly 45 scrapes the glue to make it uniform and scrape off the excess glue.

[0040] Sheathing Material Wrapping and Flattening: The glue-coated sheathing material is flattened on the template by the flattening roller, and the flattening roller can be longitudinally adjusted to adapt to templates of different thicknesses.

[0041] Cutting and Drying: The drying fan quickly dries the coated glue; the electric guide rail 62 and the cutting drive motor 66 of the cutting mechanism 6 work together to realize that the circular cutting knife 67 cuts the sheathing material between two templates along a direction at an angle to the conveying direction to achieve straight cutting, and the cutting drive motor 66 and the circular cutting knife 67 can be longitudinally adjusted through the vertical telescopic cylinder 64 to adapt to templates of different thicknesses.
