Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window production technology, and in particular to an adhesive application device for aluminum alloy door and window production. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made with aluminum alloy extruded profiles as frames, mullions, and sashes. They are also called aluminum doors and windows for short. Aluminum alloy doors and windows include those with aluminum alloy as the load-bearing material and those made of wood or plastic composites, which are also called aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows for short.

[0003] Chinese Patent Publication No. CN219702453U discloses an adhesive application device for the production of aluminum alloy doors and windows. Through a flipping mechanism, C-shaped clamps hold and fix the aluminum alloy doors and windows, preventing them from shaking during adhesive application and affecting the application effect. Simultaneously, the device can flip the aluminum alloy doors and windows, avoiding repeated disassembly and reassembly during adhesive application, thus improving the adhesive application efficiency in the production of aluminum alloy doors and windows. Through the adhesive application mechanism, a brush evenly applies the adhesive to the surface of the aluminum alloy doors and windows, ensuring a consistent adhesive thickness and improving the overall adhesive application effect in the production of aluminum alloy doors and windows.

[0004] In the aforementioned patent document, the multiple adhesive outlets on the surface of the rotating cylinder are always open. When the size of the aluminum alloy door and window to be coated is small, some adhesive outlets that do not correspond to the door and window positions will continue to dispense adhesive. This portion of adhesive cannot be applied to the surface of the aluminum alloy door and window, which is an ineffective consumption and a waste of adhesive. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the prior art: multiple glue outlets on the surface of the rotating cylinder are always open. When the size of the aluminum alloy door and window to be glued is small, some glue outlets that do not correspond to the door and window positions will continue to dispense glue. This part of the glue cannot be applied to the surface of the aluminum alloy door and window, which is an ineffective consumption and a waste of glue. Therefore, this invention proposes a glue application device for the production of aluminum alloy doors and windows.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gluing device for aluminum alloy door and window production includes a rotating cylinder with multiple glue outlet holes evenly spaced on its surface. Multiple mounting plates are fixedly mounted on the rotating cylinder in a circumferential shape via multiple sets of mounting components. Each mounting plate is located between multiple adjacent glue outlet holes. A brush is fixedly mounted on the side of each mounting plate away from the rotating cylinder. Through-holes are formed on the surface of each mounting plate. Multiple rotating rings are rotatably mounted on the rotating cylinder at equal intervals, each rotating ring located within a plurality of through-holes. Multiple through-holes are formed on the surface of each rotating ring in a circumferential shape, and each through-hole corresponds to a position of a plurality of glue outlet holes.

[0008] An L-shaped sliding plate is fixedly installed on the surface of the rotating ring. One of the mounting plates has a convex sliding opening on its surface. Multiple sliding plates are slidably arranged in multiple sliding openings. A spring rod is vertically fixedly installed on the top wall of the sliding opening. Two slots are opened on the surface of the sliding plate for the free end of the spring rod to be inserted. A pull plate is fixedly sleeved on the free end of the spring rod.

[0009] Preferably, the multiple sets of mounting components are located at both ends of multiple mounting plates. Each mounting component includes two mounting blocks that are fixedly mounted at both ends of the mounting plate and two locking bolts. The surface of the mounting block has a circular opening, and the surface of the rotating cylinder has multiple threaded holes that are symmetrically distributed in a circular pattern. The two locking bolts are movably connected in the two circular openings, and the bottom ends of the two locking bolts are threaded into the threaded holes.

[0010] Preferably, one of the mounting plates has a movement limiting component on its surface, which is used to limit the free ends of the multiple spring rods from moving in the contraction direction.

[0011] Preferably, the displacement limiting assembly includes a threaded rod horizontally rotatably mounted on the surface of the mounting plate, a T-shaped plate threaded onto the threaded rod, and a plurality of displacement limiting blocks equidistantly fixed on the surface of the T-shaped plate. The T-shaped plate is restricted from rotation by a limiting component, and the plurality of displacement limiting blocks respectively abut against a plurality of pull plates.

[0012] Preferably, the limiting component includes a rotation limiting rod, the T-shaped plate is rotatably sleeved on the rotation limiting rod, and the end of the rotation limiting rod is fixedly connected to the surface of one of the mounting plates.

[0013] Preferably, an adjusting wheel is fixedly installed at the end of the threaded rod, and a rubber layer is bonded to the surface of the adjusting wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The rotating ring and the adhesive outlet can be adjusted to flexibly adjust the opening of the adhesive outlet according to the size of the aluminum alloy doors and windows to be coated. When the opening on the rotating ring surface corresponds to the adhesive outlet, the adhesive flows out normally. Rotating the rotating ring will cause the opening to be misaligned with the adhesive outlet, thus closing the corresponding adhesive outlet. This design avoids ineffective dispensing of adhesive from extra outlets when the aluminum alloy doors and windows to be coated are small, significantly reducing adhesive waste and lowering production costs.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-4A gluing device for aluminum alloy door and window production includes a rotating cylinder 1. Multiple glue outlet holes 2 are equidistantly spaced on the surface of the rotating cylinder 1. Multiple mounting plates 3 are equidistantly mounted on the surface of the rotating cylinder 1 via multiple sets of mounting components. The mounting plates 3 are located between multiple adjacent glue outlet holes 2. A brush 4 is fixedly mounted on the side of the mounting plate 3 away from the rotating cylinder 1. Through-holes 5 are opened on the surface of the mounting plate 3. Multiple rotating rings 6 are equidistantly rotatably mounted on the rotating cylinder 1. The rotating rings 6 are located within the multiple through-holes 5. Multiple through-holes 7 are equidistantly spaced on the surface of the multiple rotating rings 6, and the positions of the multiple through-holes 7 correspond to the positions of the multiple glue outlet holes 2.

[0026] An L-shaped sliding plate 8 is fixedly installed on the surface of the rotating ring 6. One of the mounting plates 3 has a convex sliding opening 9 on its surface. Multiple sliding plates 8 are slidably arranged in multiple sliding openings 9. A spring rod 10 is vertically fixedly installed on the top wall of the sliding opening 9. Two slots 11 are opened on the surface of the sliding plate 8 for the free end of the spring rod 10 to be inserted. A pull plate 12 is fixedly sleeved on the free end of the spring rod 10.

[0027] When using this adhesive applicator for aluminum alloy door and window production, the aluminum alloy door and window to be coated is first clamped and fixed by the flipping mechanism equipped with the device to ensure that the door and window will not shake during the adhesive application process.

[0028] After fixing, observe the relative position of the rotating cylinder 1 and the aluminum alloy door and window. Based on the size of the door and window and the glue application area, accurately identify those glue outlet holes 2 on the surface of the rotating cylinder 1 that do not correspond to the position of the aluminum alloy door and window. If these glue outlet holes 2 are kept open, it will cause glue waste and they need to be sealed.

[0029] Next, adjust the rotating rings 6 corresponding to the glue outlet holes 2 that need to be sealed. By pulling the pull plate 12, the spring rod 10 is retracted, causing its free end to disengage from the slot 11 on the surface of the slide plate 8. At this time, the locking state of the rotating ring 6 is released.

[0030] Subsequently, the slide plate 8 corresponding to the dispensing hole 2 that needs to be sealed is pushed, causing it to slide within the convex sliding opening 9. The slide plate 8 drives the rotating ring 6 to rotate on the rotating cylinder 1 until it rotates to the point where another slot 11 corresponds to the end position of the spring rod 10. At this point, the multiple openings 7 on the surface of the rotating ring 6 are completely misaligned with the dispensing hole 2 that needs to be sealed. Then, the pull plate 12 is released, and the spring rod 10 returns to its original position under its own elastic force. Its free end is reinserted into the slot 11 corresponding to the surface of the slide plate 8, thus locking the rotating ring 6 again. Since the openings 7 are misaligned with the dispensing hole 2, the ring body of the rotating ring 6 will block these dispensing holes 2, preventing the adhesive from flowing out of these holes that do not need to dispense adhesive.

[0031] After completing the above adjustments, the device can be started to apply the adhesive. During the rotation of the rotating cylinder 1, only the adhesive outlets 2 corresponding to the positions of the aluminum alloy doors and windows will discharge adhesive through the aligned openings 7. The adhesive is then evenly applied to the surface of the doors and windows by the brush 4 on the mounting plate 3, which ensures the adhesive application effect and avoids the ineffective waste of adhesive.

[0032] Reference Figure 4 Multiple sets of mounting components are located at both ends of multiple mounting plates 3. The mounting components include two mounting blocks 13 that are fixedly mounted at both ends of the mounting plates 3 and two locking bolts 14. The surface of the mounting block 13 has a round opening. The surface of the rotating cylinder 1 has multiple threaded holes 15 that are symmetrically distributed in a circular shape. The two locking bolts 14 are movably connected in the two round openings, and the bottom ends of the two locking bolts 14 are threaded into the threaded holes 15 respectively.

[0033] The engagement between the locking bolt 14 and the threaded hole 15 facilitates the quick disassembly and replacement of the severely worn brush 4.

[0034] Reference Figures 5-6 One of the mounting plates 3 has a limiting component on its surface. The limiting component is used to restrict the free ends of multiple spring rods 10 from moving in the contraction direction. The limiting component includes a threaded rod 16 that is horizontally rotatably mounted on the surface of the mounting plate 3, a T-shaped plate 17 that is threaded onto the threaded rod 16, and multiple limiting blocks 18 that are equidistantly fixed on the surface of the T-shaped plate 17. The T-shaped plate 17 is restricted from rotating by a limiting component, which includes a limiting rod 19. The T-shaped plate 17 is rotatably mounted on the limiting rod 19. The end of the limiting rod 19 is fixedly connected to the surface of one of the mounting plates 3. The multiple limiting blocks 18 abut against multiple pull plates 12 respectively. An adjusting wheel is fixedly mounted on the end of the threaded rod 16. The surface of the adjusting wheel is bonded with a rubber layer.

[0035] Before applying the adhesive, after adjusting the rotating ring 6 and resetting the spring rod 10 to engage the slot 11, the multiple limiting blocks 18 are not in contact with the multiple pull plates 12, and the spring rod 10 still has room for retraction displacement.

[0036] Then the operator manually rotates the adjusting wheel at the end of the threaded rod 16. Because the T-shaped plate 17 is restricted by the rotating rod 19 and cannot rotate on its own, the T-shaped plate 17 will move horizontally along the axial direction of the threaded rod 16 under the action of the threaded transmission of the threaded rod 16.

[0037] As the T-shaped plate 17 moves, the equidistant limiting blocks 18 on its surface move synchronously until the multiple limiting blocks 18 are tightly abutted against the corresponding pull plate 12 surface. At this time, the pull plate 12 is held in place by the limiting blocks 18 and cannot be pulled upward, which indirectly restricts the free end of the spring rod 10 from moving in the contraction direction, thereby locking the position of the rotating ring 6 and ensuring that the opening or sealing state of the multiple glue outlet holes 2 is stable during the glue application process.

[0038] When the rotating ring 6 needs to be adjusted again, the adjusting wheel is rotated in the opposite direction, which drives the threaded rod 16 to reverse, causing the T-shaped plate 17 to move back, the limiting block 18 to separate from the pull plate 12, and the spring rod 10 to release its contraction restriction. The above-mentioned adjustment process of the rotating ring 6 can then be repeated to adapt to new adhesive application requirements.

[0039] By operating the displacement limiting component, abnormal conditions of the glue outlet 2 caused by equipment vibration and external interference can be effectively avoided during the glue application process, ensuring glue application efficiency and glue utilization, and improving the adaptability and stability of the device for glue application of aluminum alloy doors and windows of different sizes.

[0040] In this invention, the opening state of the adhesive outlet 2 can be flexibly adjusted according to the size of the aluminum alloy door and window to be coated, through the cooperation structure between the rotating ring 6 and the adhesive outlet 2. When the opening 7 on the surface of the rotating ring 6 corresponds to the adhesive outlet 2, the adhesive flows out normally. Rotating the rotating ring 6 to make the opening 7 and the adhesive outlet 2 misaligned can close the adhesive outlet 2 at the corresponding position. This design avoids the ineffective dispensing of adhesive from the extra adhesive outlet 2 when the size of the aluminum alloy door and window to be coated is small, significantly reducing adhesive waste and lowering production costs.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
