[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: A coating device for PE plastic film production, including a support frame 1, a processing component for coating PE plastic film is installed on the upper side of the support frame 1, the processing component includes: a support member 2, which is disposed on the support frame 1 to provide support for the bottom of the film, the support member 2 includes a cylinder assembly 21 disposed on the support frame 1, a frame 22 is provided on the top of the cylinder assembly 21, and a set of support rollers 23 are rotatably connected to the left and right sides of the top of the frame 22 respectively; a recycling box 3, which is disposed on the support frame 1 for recycling adhesive.

[0025] The coating assembly 4 is installed on the top of the support frame 1 for adhesive coating. The coating assembly 4 includes a coating roller 41 rotatably connected to the upper side of the support frame 1. The upper side of the support frame 1 is provided with a scraper 43 that fits against the left side of the coating roller 41. The top of the support frame 1 is provided with a feeding shell 46 for adhesive spraying near the upper side of the coating roller 41. The top right side of the support frame 1 is provided with a liquid pump 44 for providing adhesive to the feeding shell 46. The support frame 1 is connected with an adjusting component 47 for adjusting the adhesive coating range of the feeding shell 46. The recycling box 3 is located on the lower side of the frame 22. The frame 22 is provided with a feeding trough. The coating assembly 4 also includes a single-axis motor 42 for driving the coating roller 41 to rotate. The output end of the single-axis motor 42 is coaxially fixedly connected to the coating roller 41.

[0026] The scraper 43 is inclinedly mounted on the support frame 1. The coating assembly 4 also includes a conduit 45 installed at the discharge end of the liquid pump 44. The conduit 45 is fixedly connected to and communicates with the top middle of the loading shell 46. The liquid pump 44 is provided with a suction pipe for extracting the adhesive liquid at the suction end. The bottom of the loading shell 46 is in contact with the top of the coating roller 41. The adjusting component 47 includes two sets of adjusting blocks 475 slidably connected in the loading shell 46 for adjusting the coating range. The bottom of the adjusting blocks 475 is in contact with the surface of the coating roller 41. The adjusting block 475 is fitted with a first slide rod 474 installed at the middle of the feeding shell 46 away from the middle of the feeding shell 46. A dual-axis motor 471 is installed on the front side of the feeding shell 46. A set of screws 472 is installed at the front and rear output ends of the dual-axis motor 471 respectively. A movable block 473 is installed at the end of the screw 472 away from the dual-axis motor 471 and is fixedly connected to the first slide rod 474. The two sets of movable blocks 473 are respectively connected to a set of limiting members 476 for limiting the support roller 23 inside the support member 2.

[0027] Two sets of screws 472 with opposite thread directions and a first stop block is installed on the side away from the dual-axis motor 471. Both the single-axis motor 42 and the dual-axis motor 471 are servo motors. The first slide rod 474 is slidably connected to the loading shell 46 and the support frame 1 respectively. The dual-axis motor 471 drives the two sets of movable blocks 473, the first slide rod 474, the adjusting block 475, and the limiting member 476 to move in opposite directions through the screws 472 with opposite thread directions on both sides. The first slide rod 474 and the adjusting block 475 slide along the inside of the loading shell 46. The bottom of the adjusting block 475 slides along the film coating roller 41, so that the adjusting block 475 adjusts the internal space of the loading shell 46, thereby limiting the glue spraying range of the loading shell 46 and improving the adaptability of the glue spraying end of the device to PE plastic film of the corresponding size.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The limiting component 476 includes a second slide rod 4761 that is vertically slidably connected to the middle of the movable block 473. A second stop is installed on the top of the second slide rod 4761, and a connecting plate 4762 is installed on the bottom of the second slide rod 4761. Two sets of adjusting rods 4763 are respectively installed on both sides of the connecting plate 4762 near the support component 2. A limiting frame 4764 that is slidably connected to the outside of the support roller 23 is fixedly connected to the end of the adjusting rod 4763 away from the connecting plate 4762. The limiting frame 4764 is flush with the adjusting block 475 on the side near the support component 2, and a circular groove matching the support roller 23 is provided in the limiting frame 4764.

[0030] During the movement of the movable block 473, the adjusting block 475 pushes the second slide bar 4761 to drive the connecting plate 4762, the adjusting rod 4763, and the limiting frame 4764 to move horizontally. This makes the distance between the two sets of limiting frames 4764 on the two sets of support rollers 23 match the PE plastic film to be coated, which helps to limit the PE plastic film passing through the support rollers 23 and improve the coating accuracy.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user starts the dual-axis motor 471. The dual-axis motor 471 drives two sets of movable blocks 473, a first slide rod 474, an adjusting block 475, and a limiting member 476 to move in opposite directions via screws 472 on both sides. The first slide rod 474 and the adjusting block 475 slide along the inner side of the feeding shell 46, while the bottom of the adjusting block 475 slides along the coating roller 41. At the same time, the adjusting block 475 pushes the second slide rod 4761, causing the connecting plate 4762, the adjusting rod 4763, and the limiting frame 4764 to move horizontally. The limiting frame 4764 slides along the surface of the support roller 23. The distance between the two sets of adjusting blocks 475 and the distance between the two sets of limiting frames 4764 on the support roller 23 are adjusted to the desired coating position. After the PE plastic film is matched, the dual-axis motor 471 is turned off, and the PE plastic film to be coated is allowed to pass above the two sets of support rollers 23 and be located between the two sets of limit frames 4764. The cylinder assembly 21 drives the frame 22, the two sets of support rollers 23, and the PE plastic film to move upward, so that the upper side of the PE plastic film is in close contact with the coating roller 41. The single-axis motor 42 and the liquid pump 44 are started, and the PE plastic film is transferred through the external conveying component. The liquid pump 44 draws external adhesive, and the adhesive is sprayed onto the surface of the coating roller 41 through the conduit 45, the feeding shell 46, and the two sets of adjusting blocks 475. The single-axis motor 42 drives the coating roller 41 to rotate, and the scraper 43 spreads the adhesive evenly on the coating roller 41. Then the adhesive is coated onto the PE plastic film.
