Description

Technical Field

[0001] This utility model relates to the field of roller coating machines, and more particularly to a continuous roller coating machine for automotive interior production. Background Technology

[0002] In the automotive interior manufacturing industry, continuous adhesive application is a core process for achieving precise bonding between the surface materials of components such as seats, door panels, and headliners, including leather, fabrics, and composite panels, and the substrate.

[0003] The existing publication number CN220361425U discloses a continuous adhesive application roller for automotive interior production, including a fixed base plate. A hydraulic cylinder and a fixed side plate are provided on the upper outer surface of the fixed base plate. The hydraulic cylinder is located on one side of the fixed side plate, and a top plate is provided on the outer surface of one end of the hydraulic cylinder. This invention provides a continuous adhesive application roller for automotive interior production. The hydraulic cylinder can drive the top plate to rise and fall during use. The rising and falling of the top plate facilitates adjustment of the roller's position and height, allowing for roller application of workpieces of different thicknesses. The limiting mechanism allows the lower retaining ring to be magnetically attracted by a first and second magnetic sheet, thus closing the lower and upper retaining rings into a circle and facilitating fixation on the follower roller. The lower and upper retaining rings effectively limit the workpiece's movement, facilitating workpiece guidance and ensuring stability during roller application.

[0004] The above-mentioned device was found to have some shortcomings. Firstly, while it does provide some degree of workpiece restraint and facilitates workpiece guidance during use, the hot melt adhesive, water-based adhesive, or PUR adhesive commonly used in automotive interior coatings hardens on the surface of the follower roller after cooling, forming uneven protrusions or particles. If these are not cleaned in time, the workpiece will tilt or shift due to the uneven contact surface when being conveyed on the follower roller, resulting in deviations in the adhesive application position and directly affecting the bonding accuracy. Furthermore, the long-term accumulation of adhesive residue will accelerate the wear of the follower roller surface. At the same time, the hardened adhesive particles will affect the engagement of the lower and upper retaining rings. When there are many adhesive particles, i.e., the contact surface is thicker, the lower and upper retaining rings may not be able to engage properly, thus losing the workpiece restraint effect and causing inconvenience in actual use.

[0005] Therefore, it is necessary to provide a new continuous gluing roller for automotive interior production to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a continuous gluing roller for automotive interior production.

[0007] The continuous gluing roller for automotive interior production provided by this utility model includes: a base plate and a gluing assembly fixed on the top of the base plate. A follower roller is rotatably arranged on the top of the base plate. A limiting assembly is sleeved on the surface of the follower roller. A cleaning assembly for cleaning glue residue on the surface of the follower roller is provided on the inner side of the limiting assembly. The width of the cleaning assembly is adjustable.

[0008] Preferably, there are two limiting components, each including a retaining ring one and a retaining ring two. The retaining ring one and the retaining ring two are sleeved on the surface of the follower roller. Magnet one and magnet two are fixed at both ends of the retaining ring one and the retaining ring two, respectively, and the retaining ring one and the retaining ring two are attracted to each other by the magnet one and the magnet two.

[0009] Preferably, both sides of the first and second retaining rings have a sliding groove for the cleaning component to slide.

[0010] The cleaning assembly includes blades, each blade being annular in shape with a streamlined curved cutting edge. The number of blades is the same as the number of grooves. Multiple equally spaced mounting holes (I) are formed on the surface of each blade. Multiple equally spaced mounting holes (II) are also formed on the surface of each retaining ring (I and II). The diameters of the mounting holes (I and II) are the same. Multiple screws for adjusting the blade length are threaded to the top of each retaining ring (I and II). One end of each screw passes through the mounting hole (II) and is threaded to the inner wall of the mounting hole (I).

[0011] Preferably, a mounting plate is fixed to the top of the base plate, the mounting plate is located on one side of the roller assembly, and the two ends of the follower roller are rotatably disposed on the top of the mounting plate.

[0012] Preferably, the roller assembly includes a height adjustment component, a top plate, and rollers mounted on the surface of the top plate;

[0013] The height adjustment component includes a hydraulic rod and a telescopic rod, with the two ends of the hydraulic rod and the telescopic rod respectively fixedly connected to the top of the base plate and the bottom of the top plate.

[0014] Preferably, the glue rolling component includes a glue tank, which is fixed to the top of the top plate. A glue spraying pump is detachably connected to the inner wall of the glue tank. A glue spraying nozzle is fixed to the lower end of the glue tank, and the bottom of the glue spraying nozzle penetrates through the top plate.

[0015] Preferably, the bottom of the top plate is fixed with two side plates, one of which is fixed with a motor on one side, and a rubber roller rotates between the two side plates. One end of the rubber roller passes through the surface of one of the side plates and is fixedly connected to the rotor of the motor.

[0016] Compared with related technologies, the continuous gluing roller for automotive interior production provided by this utility model has the following advantages:

[0017] 1. This utility model provides a limiting component on the surface of the follower roller for limiting the workpiece. The limiting component can clamp the edge of the workpiece and limit its movement, which facilitates the guidance of the workpiece and ensures the stability of the workpiece during gluing. In addition, the inner side of the limiting component is also provided with a cleaning component for cleaning glue residue on the surface of the follower roller. During use, the large particles of glue layer on the surface of the follower roller can be cleaned by manually pushing the limiting component, without the need for subsequent cleaning with other tools. This solves the problem that the surface of the follower roller will harden after cooling as the gluing process progresses, forming uneven protrusions or particles, which will affect a series of problems such as subsequent gluing and limiting.

[0018] 2. This utility model features a cleaning component with an adjustable width. This allows for adjustments based on the different materials used in automotive interiors, as these materials require varying adhesive thickness and scraping pressure. Wider cleaning components increase the scraping area, preventing localized adhesive residue that could lead to uneven workpieces. Narrower cleaning components reduce scraping pressure, preventing excessive compression, deformation, or tearing of fabrics. This design offers advantages such as simple operation and excellent performance. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1 to 5 ,in, Figure 1 A schematic diagram of the integral structure of continuous adhesive coating for automotive interior production provided by this utility model; Figure 2 This is a schematic diagram of the main structure of the limiting component; Figure 3 This is a schematic diagram of the limit component. Figure 4 This is a cross-sectional structural diagram of the limiting component; Figure 5 This is a schematic diagram of the internal structure of the glue box.

[0027] In some embodiments, such as Figures 1 to 5 As shown, it includes a base plate 1 and a glue-rolling assembly fixed to the top of the base plate 1. A follower roller 31 is also rotatably provided on the top of the base plate 1. A limiting assembly for limiting the workpiece is sleeved on the surface of the follower roller 31. A cleaning assembly for cleaning glue residue on the surface of the follower roller 31 is also provided on the inner side of the limiting assembly. The width of the cleaning assembly is adjustable.

[0028] There are two limiting components, located on both sides of the workpiece edge area of ​​the follower roller 31, forming a symmetrical limiting layout. Both limiting components include a retaining ring 4 and a retaining ring 5. The retaining ring 4 and the retaining ring 5 are sleeved on the surface of the follower roller 31. The two ends of the retaining ring 4 and the retaining ring 2 are respectively fixed with magnet 41 and magnet 42, and the retaining ring 4 and the retaining ring 2 are attracted to each other by magnet 41 and magnet 42.

[0029] The design employs a split-type retaining ring: each limiting component consists of retaining ring 4 and retaining ring 5, which close end to end to form a ring-shaped limiting structure by magnetic attraction, and are fitted onto the surface of the follower roller 31. Magnets 41 and 42 are respectively embedded at the ends of retaining ring 4 and retaining ring 5, and quick closure is achieved by attraction between opposite poles. After closure, a continuous ring-shaped limiting channel is formed to constrain the workpiece conveying trajectory.

[0030] In use, the workpiece is first placed on the follower roller 31, and the two retaining rings 4 and 5 are held by hand and clamped on the edge of the workpiece to limit its position.

[0031] Both sides of the retaining ring 4 and the retaining ring 5 have a sliding groove 612 for the cleaning component to slide.

[0032] Specifically, the split-type retaining ring can flexibly adjust the closing position, is compatible with workpieces of different widths, does not require replacement of the limit components, and reduces equipment downtime and spare parts inventory costs.

[0033] Furthermore, through the magnetic closing structure, the installation and removal of the limiting component does not require tool assistance. After magnetic closing, the retaining ring 4 and retaining ring 5 form a continuous ring structure, which avoids the workpiece edge from getting stuck or moving, resulting in a low glue application position deviation rate.

[0034] The cleaning assembly includes a blade 6, which is ring-shaped with a streamlined curved surface. The curvature of the blade 6 matches the surface curvature of the follower roller 31 to ensure uniform pressure distribution on the contact surface during scraping. The number of blades 6 is the same as the number of grooves 612. Multiple equally spaced mounting holes 61 are provided on the surface ring of the blade 6. Multiple equally spaced mounting holes 611 are also provided on the surface ring of the retaining ring 4 and retaining ring 5. The diameters of the mounting holes 61 and 611 are the same. The blade 6 is axially positioned by the double-ring engagement. Multiple screws 62 for adjusting the length of the blade 6 are threaded to the top of the retaining ring 4 and retaining ring 5. One end of each screw 62 passes through the mounting hole 611 and is threaded to the inner wall of the mounting hole 61. By rotating the screws 62, one end can be inserted into different mounting holes 61, thereby adjusting the width of the blade 6. That is, adjusting the blade 6 to extend away from the retaining ring 4 or the retaining ring 5, thereby adjusting the scraping width of the blade 6.

[0035] Among them, the curved blade disperses the scraping pressure through the streamlined arc, resulting in lower pressure at a single point, thus avoiding scratches on the surface of the follower roller 31, and at the same time reducing the wear rate of the blade 6 to a certain extent.

[0036] A mounting plate 3 is fixed to the top of the base plate 1. The mounting plate 3 is located on one side of the roller assembly and is mounted on the top of the mounting plate 3, which is rotated at both ends of the follower roller 31.

[0037] Specifically, by providing a limiting component on the surface of the follower roller 31 for limiting the workpiece, the workpiece is placed on the follower roller 31, and the limiting component can clamp the edge of the workpiece, thus limiting the workpiece and facilitating its movement. This ensures the stability of the workpiece during glue rolling. Furthermore, the inner side of the limiting component is also provided with a blade 6 for cleaning glue residue on the surface of the follower roller. In use, by manually pushing the top of the retaining ring 4 or retaining ring 5, the blades on both sides of retaining ring 4 and retaining ring 2 5 are moved, thereby cleaning large particles of glue on the surface of the follower roller 31. No other tools are required for subsequent cleaning, resulting in good performance.

[0038] Furthermore, by setting up a cleaning component, the width of the blade 6 inside the cleaning component is adjustable. During cleaning, the width of the blade 6 can be adjusted according to the different materials of the car interior. Different materials have different requirements for adhesive layer thickness and scraping force. When the width of the blade 6 is widened, the blade 6 extends outward more, which can increase the scraping area and avoid local adhesive layer residue that causes unevenness of the workpiece. When the width of the blade 6 is narrowed, the scraping pressure can be reduced to prevent the fabric from being excessively squeezed, deformed or torn.

[0039] In some embodiments, reference is made to Figure 1 as well as Figure 5 As shown, the roller adhesive assembly includes a height adjustment component, a top plate 2, and roller adhesive components mounted on the surface of the top plate 2;

[0040] The height adjustment component includes a hydraulic rod 11 and a telescopic rod 12. The two ends of the hydraulic rod 11 and the telescopic rod 12 are fixedly connected to the top of the base plate 1 and the bottom of the top plate 2, respectively. The telescopic rod 12 is installed to ensure vertical stability during the lifting process.

[0041] The glue rolling component includes a glue tank 21, which is fixed to the top of the top plate 2. A glue spraying pump 211 is detachably connected to the inner wall of the glue tank 21. A glue spraying nozzle 212 is fixed to the lower end of the glue tank 21, and the bottom of the glue spraying nozzle 212 penetrates the top plate 2.

[0042] Two side plates 22 are fixed to the bottom of the top plate 2. A motor 23 is fixed to one side of one of the side plates 22. A rubber roller 24 rotates between the two side plates 22. One end of the rubber roller 24 passes through the surface of one of the side plates 22 and is fixedly connected to the rotor of the motor 23.

[0043] Among them, the glue box 21 is fixed to the top of the top plate 2, and has a built-in glue storage cavity to support the storage of different viscosities of glues such as PUR hot melt glue and water-based glue.

[0044] The glue pump 211 is connected to the inner wall of the glue tank 21 by a quick-release buckle, which allows the equipment to quickly change the type of glue and adapt to glue liquids of different viscosities and properties.

[0045] The glue nozzle 212 adopts a vertical spray design to ensure that the glue is evenly distributed on the surface of the glue roller 24, forming a continuous and stable glue film layer and improving the glue coating quality.

[0046] Specifically, the height adjustment component is mainly used to adjust the height of the glue-rolling parts. The hydraulic rod 11 can drive the top plate 2 and the telescopic rod 12 to rise and fall during use. By raising and lowering the top plate 2, the position and height of the glue-rolling cylinder 31 can be easily adjusted during use, thus facilitating the glue-rolling process for workpieces of different thicknesses.

[0047] Furthermore, during use, the drive motor 23 drives the roller 24 to rotate, and the glue is drawn by the spray pump 211 and sprayed onto the roller 31 through the spray nozzle 212.

[0048] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
