Description

Technical Field

[0001] This application relates to the field of film processing equipment technology, and in particular to a screen roller coating device for a laminating machine. Background Technology

[0002] A screen roller coating device is a piece of equipment used for precise adhesive application during material processing. The screen roller is the core component, typically a metal roller with a finely textured surface. The shape and density of the texture have a crucial impact on the amount and uniformity of adhesive application. Common texture shapes include straight lines, diagonal lines, and diamond shapes. For example, a diamond texture allows for a more even distribution of adhesive on the roller surface. Screen rollers are generally made of stainless steel or chrome-plated carbon steel, both of which offer good corrosion resistance and mechanical strength, ensuring that the roller will not deform or be damaged during long-term use. The line count (i.e., the number of lines per inch) determines the amount of adhesive applied. A higher line count results in a smaller coating amount; a lower line count results in a larger coating amount.

[0003] Patent CN210411341U discloses a screen roller coating device. This device uses a glue tank to allow the screen roller to contact the glue within, thus adhering the glue to the roller. The applicant believes that this technology has the following drawbacks: Because the workshop air contains dust and other impurities, these impurities easily adhere to the glue in the glue tank, leading to dust adhering to the tape during the screen roller coating process, thus affecting the quality of the tape coating. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a screen roller gluing device for a laminating machine.

[0005] This application can be achieved through the following technical solution: a screen roller gluing device for a laminating machine, comprising a glue tank, a screen roller rotatably mounted on the glue tank, a roller motor for driving the screen roller to rotate, and a protective cover covering the glue tank, the screen roller and the roller motor, wherein the protective cover has an inlet and an outlet for material to pass through.

[0006] In the above technical solution, the glue tank is used to hold the glue, and the inlet and outlet are used for the film to pass through. By setting a protective cover, the glue tank can protect the glue, preventing external dust from entering and contaminating the glue. A roller motor drives the screen roller to rotate, so that the screen roller can continuously pick up the glue in the glue tank.

[0007] Furthermore, the protective cover includes a housing and two maintenance doors hinged to the housing. The housing and the two maintenance doors can jointly cover the glue tank, the mesh roller and the roller motor. The housing has a through hole for a vacuum pipe to pass through.

[0008] In the above technical solution, the suction pipe can continuously remove dust from the protective cover, further ensuring the cleanliness of the glue in the glue tank.

[0009] Furthermore, the protective cover has a material filling port, through which a glue filling tube passes. A glue storage cylinder is provided outside the protective cover, and a valve is provided on the glue storage cylinder, which is connected to the glue filling tube.

[0010] In the above technical solution, when it is necessary to replenish glue in the glue tank, the valve can be opened to allow the glue in the glue storage cylinder to replenish the glue tank through the glue replenishment pipe.

[0011] Furthermore, it also includes a scraper that can contact the inner bottom surface of the glue tank. Two sliding grooves are installed at the top of the glue tank and are arranged parallel to each other. A slot is opened through the side wall of the glue tank. A sealing block that can seal the slot is installed on the glue tank. A pull ring is formed on the sealing block and is located outside the glue tank. The two sliding grooves are slidably connected to the scraper so that the scraper can move closer to or away from the slot.

[0012] In the above technical solution, the chute and the scraper are slidably connected. When it is necessary to stop work to clean the glue tank, the scraper can be pulled along the length of the chute so that the scraper can scrape the glue in the glue tank to the opening of the chute. Then the sealing block is removed so that the glue leaves the glue tank through the opening.

[0013] Furthermore, a lead screw is rotatably installed on the inner wall of the chute. The lead screw is driven to rotate by a lead screw motor. The lead screw is threadedly connected to the scraper. The rotation of the lead screw can drive the scraper to slide horizontally.

[0014] In the above technical solution, the lead screw motor drives the lead screw to rotate, so that the lead screw can drive the scraper to slide, eliminating the need for manual pulling of the scraper, which is more convenient.

[0015] Furthermore, two flexible valves capable of sealing the opening of the groove are installed on the groove, and the scraper is inserted between the two flexible valves.

[0016] In the above technical solution, the two flexible valves can block the opening of the groove. The two flexible valves at the scraper position form an open small opening, while the parts of the two flexible valves that do not contact the scraper are closed. The flexible valves can protect the lead screw to a certain extent, thus making it difficult for glue to enter the groove and adhere to the lead screw.

[0017] Furthermore, a scraper holder is installed on the glue tank, and a scraper is installed on the scraper holder, which can contact the glue on the screen roller.

[0018] In the above technical solution, the scraper can smooth the glue dipped on the screen roller, thereby ensuring that the glue can be evenly coated on the film surface.

[0019] Furthermore, the housing and maintenance door are transparent.

[0020] In the above technical solution, the transparent housing makes it easier for staff to observe the operation of the equipment inside the protective cover.

[0021] In summary, this application has the following technical advantages: the glue tank is used to hold the glue, and the inlet and outlet are used for the film to pass through. By setting a protective cover, the protective cover can protect the glue in the glue tank, preventing external dust from entering the glue tank and contaminating the glue. The roller motor drives the screen roller to rotate, so that the screen roller can continuously pick up the glue in the glue tank. Attached Figure Description

[0026] Reference Figure 1One embodiment of this application provides a screen roller gluing device for a laminating machine, including a worktable 19. A protective cover 4 is placed on the worktable 19. The protective cover 4 includes a housing 44 and two maintenance doors 45 hinged to the housing 44. A maintenance opening 43 is opened on the side wall of the housing 44. The two maintenance doors 45 can block the maintenance opening 43. When the maintenance doors 45 are closed, the housing 44 and the maintenance doors 45 together form a screen 4 with an opening. A through hole 441 is opened on the housing 44 for a vacuum pipe 5 to pass through. The vacuum pipe 5 can be connected to a vacuum cleaner to remove dust from inside the protective cover 4. The protective cover 4 covers a glue tank 1 for holding glue. A screen roller 2 that can contact the glue in the glue tank 1 is rotatably mounted on the side wall of the glue tank 1. The screen roller 2 is driven to rotate by a roller motor 3 so that glue is continuously adhered to the surface of the screen roller 2. The protective cover 4 has an inlet 41 and an outlet 42, which are respectively located on two opposite vertical side walls of the housing 44. Both the inlet 41 and outlet 42 are elongated and are used for the film to pass through. The housing 44 and the maintenance door 45 can be made of transparent acrylic sheet to allow staff to observe the operation of the equipment inside the protective cover 4 and to facilitate timely repair in case of equipment failure. A fixed frame is also installed on the glue tank 1, and a guide roller is rotatably mounted on the fixed frame. The guide roller guides the movement path of the film so that the film can contact the glue on the mesh roller 2. The protective cover 4 has several through holes for the power supply cable to pass through.

[0027] Reference Figure 1 A glue storage cylinder 7 is installed on the workbench, located above the protective cover 4. The glue storage cylinder 7 is used to store glue. A valve 8 is installed at the bottom of the glue storage cylinder 7, and a glue replenishing pipe 6 is installed at the outlet of the valve 8. A replenishing port 442 is opened at the top of the housing 44. The replenishing port 442 is used for the glue replenishing pipe 6 to pass through, and the glue replenishing pipe 6 is located directly above the glue tank 1. When it is necessary to replenish the glue in the glue tank 1, the valve 8 can be opened to allow the glue in the glue storage cylinder 7 to drip into the glue tank 1 through the valve 8 and the glue replenishing pipe 6 to replenish the glue.

[0028] Reference Figure 1 , 2Two sliding grooves 10 are installed at the top of the glue tank 1. Each sliding groove 10 has an opening and is located on either side of the axis of the screen roller 2. The two sliding grooves 10 are parallel to each other and are slidably mounted on the same scraper 9. The scraper 9 can simultaneously abut against the bottom surface of the glue tank 1 and the two opposite vertical inner sidewalls of the glue tank 1. A lead screw 14 is rotatably mounted on the inner wall of each sliding groove 10. The lead screw 14 is horizontally positioned, and a lead screw motor 15 is also installed on the sliding groove 10 to drive the lead screw 14 to rotate. A slot 11 is formed through the side wall of the glue tank 1 near the maintenance door 45. A sealing block 12 is installed on the glue tank 1 to seal the slot 11. A pull ring 13 is formed on the sealing block 12 and is located outside the glue tank 1. The pull ring 13 allows the operator to pull the sealing block 12 to remove it from the slot 11. The lead screw 14 is threadedly connected to the scraper 9. When it is necessary to stop work to clean the glue in the glue tank 1, first remove the screen roller 2 and roller motor 3, and then drive the lead screw motor 15 to rotate the lead screw 14. The rotation of the lead screw 14 can make the scraper 9 slide along the length of the chute 10, thereby pushing the glue in the glue tank 1 in a straight line to the groove opening 11 until the glue leaves the glue tank 1. This design facilitates the cleaning of the glue tank 1 when the equipment needs to be stopped.

[0029] Reference Figure 1 Two flexible valves 16, made of rubber, are installed at the top of the slide groove 10. These valves shield the opening of the slide groove 10. A scraper 9 passes between the two valves. At the scraper 9, the two valves 16 form a small open opening, while the parts of the valves 16 not in contact with the scraper 9 are closed. The flexible valves 16 provide some protection for the lead screw 14, preventing glue from easily entering the slide groove 10 and adhering to the lead screw 14. By using two lead screws 14, the scraper 9 can be driven more evenly at both ends.

[0030] Reference Figure 1 A scraper holder 17 is installed on the glue tank 1, and a scraper 18 is installed on the scraper holder 17. The scraper 18 can scrape the glue dipped on the screen roller 2 to smooth it out, thereby ensuring that the glue can be evenly coated on the film surface.

[0031] The working principle of this embodiment is as follows: The roller motor 3 drives the screen roller 2 to rotate and pick up the glue in the glue tank 1. The scraper 18 can scrape the glue picked up on the screen roller 2 to smooth it out, thereby ensuring that the glue can be evenly applied to the film surface. By setting a protective cover 4, the protective cover 4 can cover the screen roller 2 and the glue tank 1, which can protect the glue in the glue tank 1 and prevent external dust from entering the glue tank 1 and contaminating the glue.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
