Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, specifically a glue coating device for processing plastic products. Background Technology

[0002] Plastics are materials primarily composed of resin, containing additives, and capable of being molded into shape during processing. Plastics do not contain fibers, coatings, or binders. They are high-molecular polymers that are lightweight, durable, and highly malleable. There are many types of plastics, including polyethylene, polypropylene, and polyvinyl chloride.

[0003] Plastic sheets are sheet-like products made of polymer materials. During the production and processing of plastic sheets, some processes require coating their surface with adhesive to improve their wear resistance and antistatic properties.

[0004] When applying adhesive to plastic sheets, a roller coater is typically used. The plastic sheet is placed on the conveyor belt of the roller coater, which then transports it to the bottom of the rollers for coating. However, if the plastic sheet is placed at an angle, the contact angle between the plastic sheet and the rollers will change, resulting in uneven adhesive application. Therefore, this invention provides an adhesive coating device for processing plastic products. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A glue-coating device for processing plastic products, comprising a worktable, a first motor fixedly connected to the side wall of the worktable, an active roller fixedly connected to the output end of the first motor through the worktable, the end of the active roller rotatably mounted on another side wall of the worktable, a driven roller rotatably mounted in the middle of the worktable, a conveyor belt installed between the active roller and the driven roller, a first bracket fixedly connected to the top of the worktable, a second motor fixedly connected to the top of the first bracket, a lead screw fixedly connected to the output end of the second motor through the first bracket, a slider slidably connected in the middle of the lead screw, symmetrical through holes in the middle of the first bracket, a sliding rod slidably connected in the through holes, a clamping plate fixedly connected to the end of the sliding rod, the clamping plates being symmetrically arranged, a pull rod hinged to the side wall of the slider, the end of the pull rod being hinged to the side wall of the clamping plate; by providing clamping plates, plastic sheets of different sizes can be limited and guided, straightening plastic sheets placed skewed on the conveyor belt, reducing the phenomenon of uneven glue coating caused by the skewed placement of the plastic sheets.

[0007] Preferably, a coating assembly is installed on the top of the workbench. The coating assembly includes fixed blocks, which are fixed to the top of the workbench and symmetrically arranged. A coating roller and a support roller are rotatably mounted between the symmetrically arranged fixed blocks. A third motor is fixed to the side wall of one of the fixed blocks, and the output end of the third motor is fixed to the end of the coating roller. A fourth motor is fixed to the side wall of the other fixed block, and the output end of the fourth motor is fixed to the end of the support roller. A second bracket is fixed to the top of the fixed blocks, and a glue box is fixed to the middle of the second bracket. A glue inlet pipe is connected to the top of the glue box, and multiple glue spraying heads are connected to the bottom of the glue box. By setting up the coating assembly, after the coating roller is evenly coated with glue, the conveyor belt moves the plastic sheet below the coating roller and the support roller. The coating roller rolls on the surface of the plastic sheet, evenly applying glue to the surface of the plastic sheet, thus realizing the coating of the plastic sheet.

[0008] Preferably, the side wall of the clamping plate is fixed with an extension plate, and the extension plate is inclined. By providing the extension plate, when the plastic plate on the surface of the conveyor belt is placed at an inclination, the plastic plate will slide forward along the surface of the extension plate after contacting the surface of the extension plate and enter the gap between the symmetrically arranged clamping plates. The extension plate guides the plastic plate and guides the inclined plastic plate into the gap between the clamping plates.

[0009] Preferably, multiple rubber pads are fixedly connected to the middle portions of the extension plate and the clamping plate, and the rubber pads are arranged in an array structure; by providing rubber pads, the wear of the plastic plate can be reduced when the clamping plate and the extension plate guide and limit the plastic plate.

[0010] Preferably, an air chamber is fixedly connected between the fixed blocks, an air pump is fixedly connected to the top of the air chamber, the air pump is connected to the air chamber, and multiple air jets are connected to the bottom of the air chamber; by providing air jets, after the plastic sheet is coated with glue, when the conveyor belt drives the plastic sheet to pass under the air jets, the airflow blown out by the air jets dries the glue on the plastic sheet.

[0011] Preferably, a control box is installed on the top of the workbench. The control box is used to control the start and stop of the first motor, the second motor, the third motor, the fourth motor, and the air pump. By providing the control box, the start and stop of the first motor, the second motor, the third motor, the fourth motor, and the air pump can be controlled.

[0023] like Figure 1 , Figure 2As shown, this utility model discloses a glue-coating device for processing plastic products, comprising a worktable 11, a first motor 12 fixedly connected to the side wall of the worktable 11, a drive roller 13 fixedly connected to the output end of the first motor 12 through the worktable 11, an end of the drive roller 13 rotatably mounted on the side wall of another worktable 11, a driven roller 14 rotatably mounted in the middle of the worktable 11, a conveyor belt 15 installed between the drive roller 13 and the driven roller 14, and a first support 16 fixedly connected to the top of the worktable 11. A second motor 17 is fixedly connected to the top of the first bracket 16. A lead screw 18 is fixedly connected to the output end of the second motor 17 through the first bracket 16. A slider 19 is slidably connected to the middle of the lead screw 18. Symmetrical through holes 102 are provided in the middle of the first bracket 16. A sliding rod 103 is slidably connected within the through holes 102. A clamping plate 1 is fixedly connected to the end of the sliding rod 103. The clamping plates 1 are symmetrically arranged. A pull rod 101 is hinged to the side wall of the slider 19. The end of the pull rod 101 is hinged to the side wall of the clamping plate 1. In use, the first motor 12 is started, driving the drive roller 13 to rotate. The drive roller 13 drives the driven roller 14 to rotate synchronously via the conveyor belt 15. The plastic sheet to be coated is placed on the conveyor belt 15, which transports the plastic sheet forward. The second motor 17 is started, driving the lead screw 18 to rotate. At this time, the slider 19 slides upward on the lead screw 18, and the pull rod 101 moves upward synchronously. At this time, the slide rod 103 slides within the through hole 102, and the symmetrically arranged clamping plates 1 are relatively close to each other. When the gap between the symmetrically arranged clamps 1 is slightly larger than the plastic sheet, the second motor 17 is turned off. At this time, the plastic sheet is conveyed forward on the conveyor belt 15 through the gap between the clamps 1. The clamps 1 can limit the plastic sheet and reduce the phenomenon of uneven glue application caused by the plastic sheet being placed on the conveyor belt 15 with an skewed position. By setting the clamps 1, plastic sheets of different sizes can be limited and guided, and plastic sheets that are placed on the conveyor belt 15 with an skewed position can be straightened, reducing the phenomenon of uneven glue application caused by the skewed position of the plastic sheet.

[0024] like Figure 1 , Figure 4 , Figure 5As shown, a glue-coating assembly 2 is installed on the top of the workbench 11. The glue-coating assembly 2 includes a fixing block 21, which is fixed to the top of the workbench 11 and is symmetrically arranged. A glue-applying roller 23 and a support roller 25 are rotatably mounted between the symmetrically arranged fixing blocks 21. A third motor 22 is fixed to the side wall of one of the fixing blocks 21, and the output end of the third motor 22 is fixed to the end of the glue-applying roller 23. A fourth motor 24 is fixed to the side wall of the other fixing block 21, and the output end of the fourth motor 24 is fixed to the end of the support roller 25. A second bracket 26 is fixed to the top of the fixing block 21, and a glue box 27 is fixed to the middle of the second bracket 26. A glue inlet pipe 29 is connected to the top of the glue box 27, and multiple glue spraying heads 28 are connected to the bottom of the glue box 27. In use, the third motor 23 is started. The adhesive coating assembly 2 and the fourth motor 24 drive the adhesive coating roller 23 and the support roller 25 to rotate, respectively, adding glue to the glue inlet pipe 29. The glue enters the glue box 27 and then flows out from multiple glue spray nozzles 28 connected to the bottom of the glue box 27, dripping onto the surface of the rotating adhesive coating roller 23. After the adhesive coating roller 23 is evenly coated, the conveyor belt 15 moves the plastic sheet below the adhesive coating roller 23 and the support roller 25. The adhesive coating roller 23 rolls on the surface of the plastic sheet, evenly applying the glue to the surface of the plastic sheet, thus achieving the adhesive coating of the plastic sheet. By setting the adhesive coating assembly 2, after the adhesive coating roller 23 is evenly coated, the conveyor belt 15 moves the plastic sheet below the adhesive coating roller 23 and the support roller 25. The adhesive coating roller 23 rolls on the surface of the plastic sheet, evenly applying the glue to the surface of the plastic sheet, thus achieving the adhesive coating of the plastic sheet.

[0025] like Figure 1 , Figure 2 As shown, an extension plate 3 is fixed to the side wall of the clamping plate 1, and the extension plate 3 is inclined. In use, after setting the distance between the clamping plates 1 according to the size of the plastic plate, the plastic plate is placed on the conveyor belt 15. The conveyor belt 15 drives the plastic plate forward. When the plastic plate on the surface of the conveyor belt 15 is tilted, the plastic plate will slide forward along the surface of the extension plate 3 after contacting it, and enter the gap between the symmetrically arranged clamping plates 1. The extension plate 3 guides the plastic plate, guiding the tilted plastic plate into the gap between the clamping plates 1. By setting the extension plate 3, when the plastic plate on the surface of the conveyor belt 15 is tilted, the plastic plate will slide forward along the surface of the extension plate 3 after contacting it, and enter the gap between the symmetrically arranged clamping plates 1. The extension plate 3 guides the plastic plate, guiding the tilted plastic plate into the gap between the clamping plates 1.

[0026] like Figure 1 , Figure 2As shown, multiple rubber pads 4 are fixedly connected to the middle parts of the extension plate 3 and the clamping plate 1, and the rubber pads 4 are arranged in an array structure. By providing rubber pads 4, the wear of the plastic plate can be reduced when the clamping plate 1 and the extension plate 3 guide and limit the plastic plate.

[0027] like Figure 1 , Figure 5 As shown, an air chamber 51 is fixedly connected between the fixed blocks 21. An air pump 52 is fixedly connected to the top of the air chamber 51 and is connected to the air chamber 51. Multiple air jets 5 are connected to the bottom of the air chamber 51. In use, the air pump 52 is started, and the air pump 52 generates airflow that enters the air chamber 51. Then, the multiple air jets 5 spray downwards. After the plastic sheet is coated with glue, when the conveyor belt 15 carries the plastic sheet past the air jets 5, the airflow blown by the air jets 5 dries the glue on the plastic sheet. By setting the air jets 5, after the plastic sheet is coated with glue, when the conveyor belt 15 carries the plastic sheet past the air jets 5, the airflow blown by the air jets 5 dries the glue on the plastic sheet.

[0028] like Figure 1 As shown, a control box 6 is installed on the top of the workbench 11. The control box 6 is used to control the start and stop of the first motor 12, the second motor 17, the third motor 22, the fourth motor 24, and the air pump 52. By setting the control box 6, the start and stop of the first motor 12, the second motor 17, the third motor 22, the fourth motor 24, and the air pump 52 can be controlled.

[0029] Working principle: During use, the first motor 12 is started, driving the drive roller 13 to rotate. The drive roller 13 drives the driven roller 14 to rotate synchronously via the conveyor belt 15. The plastic sheet to be coated is placed on the conveyor belt 15, which transports the plastic sheet forward. The second motor 17 is started, driving the lead screw 18 to rotate. At this time, the slider 19 slides upward on the lead screw 18, and the pull rod 101 moves upward synchronously. At this time, the slide rod 103 slides within the through hole 102, and the symmetrically arranged clamping plates 1 are relatively close to each other. When the gap between the symmetrically arranged clamping plates 1 is slightly larger than the plastic sheet, the second motor 17 is turned off. At this time, the plastic sheet is conveyed forward on the conveyor belt 15 through the gap between the clamping plates 1. The clamping plates 1 can limit the plastic sheet, reducing the uneven glue application caused by the plastic sheet being placed skewed on the conveyor belt 15. The third motor 22 and the fourth motor 24 are started. The glue coating assembly 2 and the fourth motor 24 drive the glue coating roller 23 and the support roller 25 to rotate respectively, adding glue to the glue inlet pipe 29. The glue enters the glue box 27 and is then dispensed by the glue... Multiple glue nozzles 28 connected to the bottom of box 27 flow downwards and drip onto the surface of rotating glue-applying roller 23. After the glue-applying roller 23 is evenly coated with glue, the conveyor belt 15 moves the plastic sheet below the glue-applying roller 23 and support roller 25. The glue-applying roller 23 rolls on the surface of the plastic sheet, evenly applying glue to the surface of the plastic sheet, thus achieving glue application to the plastic sheet. After setting the distance between clamping plates 1 according to the size of the plastic sheet, the plastic sheet is placed on the conveyor belt 15. The conveyor belt 15 moves the plastic sheet forward. When the plastic sheet on the surface of the conveyor belt 15 swings... When tilted, the plastic sheet slides forward along the surface of the extension plate 3 after contacting the extension plate 3, and enters the gap between the symmetrically arranged clamps 1. The extension plate 3 guides the plastic sheet, guiding the tilted plastic sheet into the gap between the clamps 1. The air pump 52 is started, and the air pump 52 generates airflow that enters the air chamber 51, and then sprays it downward by multiple jet nozzles 5. After the plastic sheet is coated with glue, when the conveyor belt 15 carries the plastic sheet past the jet nozzles 5, the airflow blown out by the jet nozzles 5 dries the glue on the plastic sheet.
