Description

Technical Field

[0001] This utility model relates to the field of building exterior wall engineering technology, specifically to a joint sealing device for prefabricated walls. Background Technology

[0002] In prefabricated buildings, the exterior walls are usually assembled from multiple prefabricated components. Sealing and waterproofing at the joints are key to ensuring the quality of the building. Traditional manual caulking and coating methods are inefficient, produce inconsistent quality, and require highly skilled workers.

[0003] According to a prefabricated building exterior wall joint caulking device (Announcement No.: CN221823317U), the above application includes a base; a support frame, which is vertically arranged at the front of the upper end face of the base; a material supply box, which is arranged on the upper end face of the base and located at the rear side of the support frame; the support frame is provided with a lifting mechanism, the lifting mechanism is provided with a movable plate, and the front side of the movable plate is provided with a translation component.

[0004] However, the above-mentioned caulking device can only process one gap at a time, which means that it is necessary to move and adjust the position one gap at a time. Each time the gap is switched, the operator has to realign the center of the joint, resulting in low overall construction efficiency and making it unsuitable for large-area continuous operation. In view of this, we propose a caulking device for joints of prefabricated walls. Utility Model Content

[0005] The purpose of this invention is to provide a joint sealing device for prefabricated walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a joint sealing device for prefabricated walls, comprising a frame, wherein a translation component for controlling the movement of the sealing device is provided inside the frame, the translation component includes a drive motor fixedly connected to the top end face of the frame, a screw fixedly connected to the output end of the drive motor, a movable frame threadedly connected to the side wall of the screw, a drive motor fixedly connected to the side wall of the movable frame, a screw fixedly connected to the output end of the drive motor, a threaded block threadedly connected to the side wall of the screw, and a sealing component for filling the gaps in the wall provided on the side wall of the threaded block.

[0007] Preferably, the first screw and the second screw are set at a 90-degree angle, the movable frame is slidably connected to the inner wall of the frame, and the threaded block is slidably connected to the inner wall of the movable frame.

[0008] Preferably, the glue applicator includes a rotating frame rotatably connected to the side wall of the threaded block, a servo motor fixedly connected to the side wall of the rotating frame, a bidirectional screw fixedly connected to the output end of the servo motor, a mounting base threadedly connected to the side wall of the bidirectional screw, a glue applicator head fixedly connected to the side wall of the mounting base, a scraper first provided on the side wall of the mounting base, and a scraper second fixedly connected to the side wall of the mounting base.

[0009] Preferably, there are two sets of mounting seats, each set of which is threadedly connected to a bidirectional screw. The mounting seats are slidably connected to the inner wall of the rotating frame, allowing for simultaneous application of sealant to two seams.

[0010] Preferably, a connecting pipe is fixedly connected to the outer wall of the mounting base, the connecting pipe is fixedly connected to the material supply box, the material supply box is fixedly connected to the top end face of the frame, and the connecting pipe is connected to the glue applicator head to supply glue to the glue applicator head.

[0011] Preferably, the outer wall of the rotating frame is threaded with a positioning bolt, which is movably connected to the side wall of the threaded block. The inner wall of the rotating frame is fixedly connected with a baffle, which blocks the dust and colloid scraped off by the first and second scrapers above.

[0012] Preferably, the scraper is sleeved with a locking bolt, and the locking bolt is threadedly connected to the mounting base, thereby fixing the angle of the scraper.

[0013] Compared with the prior art, this utility model provides a joint sealing device for prefabricated walls, which has the following advantages:

[0014] 1. This joint sealing device for prefabricated walls, through its set sealing components and adjustable spacing between two sets of sealing heads, can quickly adapt to different panel sizes without changing tools. The first scraper removes dust and debris from the inside of the joint, preventing impurities from affecting the adhesion between the adhesive and the concrete or panel, thus improving sealing quality. The second scraper abuts against the outside of the wall, removing excess adhesive to ensure a smooth and full seal, preventing bulges or uneven application. The sealing components can rotate along the threaded block, allowing the two sets of sealing heads to switch between horizontal and vertical distribution, adapting to both vertical and horizontal joints in exterior walls. Since the angle switching is fixed by positioning bolts, the direction of the sealing heads is stable, preventing loosening or displacement during operation and ensuring more consistent construction quality.

[0015] 2. This joint sealing device for prefabricated walls allows for fine-tuning of the scraper's angle via locking bolts, enabling better application to gaps of varying widths. This ensures the scraper remains in full contact with the inner wall of the gap, thoroughly removing dust and debris and preventing inadequate cleaning or excessive scraping, thus guaranteeing effective joint cleaning.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a joint sealing device for prefabricated walls, including a frame 1. Inside the frame 1 is a translation component 2 for controlling the movement of the sealing device. The translation component 2 includes a drive motor 201 fixedly connected to the top end face of the frame 1. A screw 202 is fixedly connected to the output end of the drive motor 201. A movable frame 203 is threadedly connected to the side wall of the screw 202. A drive motor 204 is fixedly connected to the side wall of the movable frame 203. The output end is fixedly connected to screw 205, and screw 205 is threadedly connected to the side wall of screw 205. Screw 1 202 and screw 205 are set at a 90-degree angle. The movable frame 203 is slidably connected to the inner wall of the frame 1. Threaded block 206 is slidably connected to the inner wall of the movable frame 203. By controlling screw 1 202 and screw 205, the glue applicator 305 can move laterally or longitudinally to apply glue to the joint. The side wall of threaded block 206 is provided with a glue applicator component 3 for filling the gaps in the wall.

[0022] In one embodiment of this utility model, the glue applicator 3 includes a rotating frame 301 rotatably connected to the side wall of the threaded block 206. A servo motor 302 is fixedly connected to the side wall of the rotating frame 301. A bidirectional screw 303 is fixedly connected to the output end of the servo motor 302. A mounting base 304 is threadedly connected to the side wall of the bidirectional screw 303. A glue applicator head 305 is fixedly connected to the side wall of the mounting base 304. A scraper 1 306 is provided on the side wall of the mounting base 304. A scraper 2 307 is fixedly connected to the side wall of the mounting base 304.

[0023] There are two sets of mounting seats 304. The two sets of mounting seats 304 are threadedly connected to the bidirectional screw 303. The mounting seats 304 are slidably connected to the inner wall of the rotating frame 301, which can simultaneously apply glue to two seams. The outer wall of the mounting seat 304 is fixedly connected to the connecting pipe 4, which is fixedly connected to the material supply box 5. The material supply box 5 is fixedly connected to the top end face of the frame 1. The connecting pipe 4 is connected to the glue application head 305, and glue is supplied to the glue application head 305 through the connecting pipe 4. The outer wall of the rotating frame 301 is threadedly connected to the positioning bolt 309, which is movably connected to the side wall of the threaded block 206. The inner wall of the rotating frame 301 is fixedly connected to the baffle 308, which blocks the dust and glue scraped off by the scraper 1 306 and scraper 2 307 above.

[0024] Servo motor 302 controls bidirectional screw 303, causing mounting base 304 to move in opposite directions or in the opposite direction, thereby adjusting the spacing between the two sets of adhesive application heads 305. This allows for quick adaptation to different board sizes without the need to change tooling. Scraper 1 306 extends into the joint and scrapes the inside of the joint during the translation component 2's drive process, removing dust and debris to prevent impurities from affecting the adhesion of the adhesive to the concrete or board, thus improving the sealing quality. Then, adhesive application head 305 applies adhesive to the joint. Finally, scraper 2 307 abuts against the outside of the wall to remove excess adhesive, resulting in a smooth and full adhesive joint appearance, preventing bulges or uneven application.

[0025] The caulking assembly 3 can rotate along the threaded block 206, allowing the two sets of caulking heads 305 to switch between horizontal and vertical distribution, adapting to the vertical and horizontal joints of the exterior wall. Then, the positioning bolt 309 is rotated to control the angle of the rotating frame 301. Since the angle switching is fixed by the positioning bolt 309, the direction of the caulking head 305 can be kept stable, avoiding loosening and displacement during operation, resulting in more stable construction quality.

[0026] In addition, scraper 306 is sleeved with locking bolt 6, and locking bolt 6 is threaded to mounting base 304. The angle of scraper 306 is fixed by locking bolt 6. The angle of scraper 306 can be finely adjusted and then locked, which can better fit gaps of different widths and ensure that the scraper is always in full contact with the inner wall of the gap, so as to thoroughly remove dust and debris and avoid incomplete cleaning or excessive scraping, thus ensuring the cleaning effect of the gap.

[0027] In this utility model, during use, the servo motor 302 controls the bidirectional screw 303, causing the mounting base 304 to move in opposite directions or in the opposite direction, thereby adjusting the distance between the two sets of adhesive heads 305. This allows for quick adaptation to different board sizes. The scraper 306 extends into the joint and scrapes the inside of the joint during the driving process of the translation component 2, removing dust and debris to prevent impurities from affecting the adhesion between the adhesive and the concrete or board. The adhesive head 305 applies adhesive to the joint. Finally, the scraper 307 abuts against the outside of the wall to scrape off any excess adhesive, resulting in a smooth adhesive joint.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
