Description

Technical Field

[0001] This invention belongs to the field of glass fiber membrane processing technology, and relates to a coating device for glass fiber membrane. Background Technology

[0002] Polytetrafluoroethylene (PTFE) fiberglass cloth is a high-performance, multi-purpose composite material made by impregnating high-performance fiberglass cloth with a suspended PTFE (commonly known as "plastic king") emulsion. In the current production process, adhesive is applied to the fabric using a coating machine to ensure the bonding between the fiberglass membranes. During continuous production, adhesive is continuously applied and transferred to the fabric. Once the adhesive dries, the fiberglass is bonded. However, when the coating machine is first started, the adhesive adheres unevenly to the impregnation rollers, requiring a trial run before normal production can begin. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a gluing device for glass fiber membranes, which features a liftable gluing roller for easy application of adhesive and improved production efficiency.

[0004] The objective of this invention can be achieved through the following technical solution: A coating device for glass fiber membrane material, comprising a glue storage tank, a motor, a coating roller, two coating vertical plates, and a coating top plate, characterized in that the two coating vertical plates are respectively vertically fixed to the side plates of the glue storage tank, the coating top plate is fixedly connected to the top of the coating vertical plates, the motor is fixed to the coating top plate, the two shaft ends of the coating roller are respectively rotatably connected to the two coating vertical plates, a drive pulley is fixed on the output shaft of the motor, the left shaft end of the coating roller extends out of the coating vertical plate and is fixed with a driven pulley, the drive pulley and the driven pulley are connected by a belt ring, and the device is located below the coating top plate. The end face is connected to the glue application assembly, which includes a lifting cylinder fixed to the lower end face of the glue application top plate, a lifting frame fixed to the lower end of the telescopic rod of the lifting cylinder, and a glue-dipping roller. The lifting frame is concave, and the glue-dipping roller is rotatably connected to the lifting frame. The glue-dipping roller is parallel to the glue application roller and located below the glue application roller. Long strip-shaped clearance sliding holes are opened on both sides of the lifting frame. The two shaft ends of the glue application roller pass through the clearance sliding holes. A fixed gear and a moving gear are respectively connected to the right shaft ends of the glue-dipping roller and the glue application roller. When the lifting frame moves to the highest position, the fixed gear and the moving gear mesh. A glue scraping assembly that can scrape the glue-dipping roller and the glue application roller at the same time is provided on the front side of the lifting frame.

[0005] The fiberglass membrane material passes over the gluing roller, carrying away the glue on the roller. The motor drives the gluing roller to rotate, and the gluing roller, through gear meshing, drives the dip roller to rotate. The dip roller is partially submerged in the glue storage tank. Before gluing and laminating the fiberglass membrane material, to facilitate more and more comprehensive glue adhesion to the surface of the dip roller, the lifting cylinder is activated to move the lifting frame downward, so that the dip roller is completely immersed in the glue. After being fully coated with glue, it returns to its original position, allowing the two fixed gears and the moving gear to re-mesh.

[0006] Furthermore, the glue-scraping assembly includes a squeezing cylinder, two swing plates hinged to the lifting frame, a glue-scraping main shaft connected between the two swing plates, a glue-scraping triangular plate fitted on the glue-scraping main shaft, and a scraper at both ends of the scraper. The two scrapers can abut against the glue-applying roller and the glue-dipping roller respectively. The squeezing cylinder is fixed on the glue-applying vertical plate. The lower end of the extension rod of the squeezing cylinder is connected to a squeezing plate, which abuts against the swing plates. An extension spring is connected to the inner side of the swing plates, and the inner end of the extension spring is connected to the lifting frame.

[0007] Under the action of the extension spring, the swing plate swings outward, causing the scraper to disengage from the glue-applying roller and the glue-dipping roller. When it is necessary to clean the glue on the glue-applying roller and the glue-dipping roller, the extrusion cylinder is activated. Driven by the extrusion cylinder, the extrusion plate squeezes the swing plate inward, compressing the extension spring and causing the scraper to press against the glue-applying roller and the glue-dipping roller, scraping off the solidified glue on the roller surface.

[0008] Furthermore, there are two scraping triangle plates that are rotatably sleeved on the scraping spindle, and the scraper is fixedly connected between the two scraping triangle plates.

[0009] Furthermore, the swing plate is arc-shaped, and a through hole is opened at the outer end of the swing plate for the glue scraping spindle to pass through.

[0010] Furthermore, the lifting frame is attached to the glued upright plate on both sides, and a guide rail is fixed on the inner side of the glued upright plate. The lifting frame is embedded in the guide rail, and a limit block is also fixed on the inner side of the glued upright plate. After the lifting frame moves up to a certain position, it abuts against the limit block.

[0011] Compared with existing technologies, the coating device for this glass fiber membrane has the following advantages:

[0012] 1. When starting the machine, directly immerse the glue-dipping roller into the glue storage tank to ensure that the glue adheres quickly and evenly, thereby increasing production efficiency.

[0013] 2. Features a scraper assembly for cleaning solidified adhesive, allowing for one-time cleaning of the application roller and the dipping roller. Two scrapers can be tightly attached to the roller surfaces of the upper and lower rollers. Attached Figure Description

[0018] like Figure 1 As shown, the adhesive coating device for this fiberglass membrane material includes an adhesive storage tank 1, a motor 2, an adhesive roller 3, two adhesive coating uprights 4, and an adhesive coating top plate 5. The two adhesive coating uprights 4 are vertically fixed on the two side plates of the adhesive storage tank 1, and the adhesive coating top plate 5 is fixedly connected to the top of the adhesive coating uprights 4. The motor 2 is fixed on the adhesive coating top plate 5. The two shaft ends of the adhesive roller 3 are rotatably connected to the two adhesive coating uprights 4, and a drive pulley 6 is fixed on the output shaft of the motor 2. The left shaft end of the adhesive roller 3 passes through the adhesive coating uprights 4 and is fixed with a driven pulley 7. The drive pulley 6 and the driven pulley 7 are connected by a leather ring 8.

[0019] like Figure 2 As shown, an adhesive application assembly is connected to the lower end face of the adhesive coating top plate 5. The adhesive application assembly includes a lifting cylinder 9 fixed to the lower end face of the adhesive coating top plate 5, a lifting frame 10 fixed to the lower end of the telescopic rod of the lifting cylinder 9, and an adhesive dipping roller 11. The lifting frame 10 is concave. The adhesive dipping roller 11 is rotatably connected to the lifting frame 10. The adhesive dipping roller 11 is parallel to the adhesive application roller 3 and located below the adhesive application roller 3. Long strip-shaped clearance sliding holes 12 are opened on both side plates of the lifting frame 10. The two shaft ends of the adhesive application roller 3 pass through the clearance sliding holes 12. A fixed gear 13 and a moving gear 14 are respectively connected to the right shaft ends of the adhesive dipping roller 11 and the adhesive application roller 3. When the lifting frame 10 moves to the highest position, the fixed gear 13 and the moving gear 14 mesh.

[0020] The lifting frame 10 is attached to the glued upright plate 4 on both sides. The inner side of the glued upright plate 4 is fixed with a guide rail 22. The lifting frame 10 is embedded in the guide rail 22. The inner side of the glued upright plate 4 is also fixed with a limit block 23. After the lifting frame 10 moves up to a certain position, it abuts against the limit block 23.

[0021] like Figure 3As shown, the front side of the lifting frame 10 is equipped with a scraping assembly that can simultaneously scrape the dip roller 11 and the top roller 3. The scraping assembly includes a squeezing cylinder 15, two swing plates 16 hinged to the lifting frame 10, and a scraping main shaft 17 connected between the two swing plates 16. A scraping triangle plate 18 is sleeved on the scraping main shaft 17. Both ends of the scraping triangle plate 18 have scrapers 19. The two scrapers 19 can abut against the top roller 3 and the dip roller 11 respectively. The squeezing cylinder 15 is fixed on the glue-applying vertical plate 4. The lower end of the extension rod of the squeezing cylinder 15 is connected to a squeezing plate 20. The squeezing plate 20 abuts against the swing plates 16. An extension spring 21 is connected to the inner side of the swing plates 16. The inner end of the extension spring 21 is connected to the lifting frame 10.

[0022] Two scraping triangle plates 18 are rotatably sleeved on the scraping spindle 17. The scraper 19 is fixedly connected between the two scraping triangle plates 18. The swing plate 16 is arc-shaped, and the outer end of the swing plate 16 has a through hole for the scraping spindle 17 to pass through.

[0023] Under the action of the extension spring 21, the swing plate 16 swings outward, causing the scraper 19 to disengage from the glue-applying roller 3 and the glue-dipping roller 11. When it is necessary to clean the glue on the glue-applying roller 3 and the glue-dipping roller 11, the extrusion cylinder 15 is activated. Driven by the extrusion cylinder 15, the extrusion plate 20 squeezes the swing plate 16 inward, compressing the extension spring 21, thereby causing the scraper 19 to press against the glue-applying roller 3 and the glue-dipping roller 11, scraping off the solidified glue on the roller surface.

[0024] Workflow: The fiberglass membrane material passes over the top of the gluing roller 3, carrying away the adhesive on the gluing roller 3. The motor 2 drives the gluing roller 3 to rotate, and the gluing roller 3 drives the dip roller 11 to rotate through gear meshing. The dip roller 11 is partially submerged in the adhesive storage tank 1. Before gluing and laminating the fiberglass membrane material, in order to facilitate more and more comprehensive adhesion of adhesive to the roller surface of the dip roller 11, the lifting cylinder 9 is activated to drive the lifting frame 10 to move down, so that the dip roller 11 is completely immersed in the adhesive. After being fully coated with adhesive, it returns to its original position, so that the two fixed gears 13 and the moving gear 14 re-mesh.
