Description

Technical Field

[0001] This utility model is a device for smoothing decorative paper in architectural decoration, belonging to the field of architectural decoration. Background Technology

[0002] Decorative paper is an essential raw material in building materials. In the product structure, it is placed under the surface paper, primarily serving to provide decorative patterns and to cover and prevent the underlying adhesive from seeping through. After the decorative paper is pasted, it needs to be smoothed with tools to ensure a smooth adhesion. During the pasting process, uneven application of adhesive to the back of the decorative paper can create excess air bubbles or adhesive residue. Smoothing out these excess air bubbles and adhesive residue is necessary to ensure the decorative paper adheres flat and firmly to the wall.

[0003] Most existing smoothing methods involve smoothing the decorative paper by moving a roller up and down. However, the rollers can become damaged after prolonged use and need to be replaced, which is inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for smoothing decorative paper in architectural decoration.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A device for smoothing decorative paper in architectural decoration includes a fixed frame. A motor is fixed to the bottom inner side of the fixed frame. The output end of the motor is connected to one end of a lead screw. The other end of the lead screw is rotatably connected to the top inner side of the fixed frame. A movable block is threaded onto the lead screw. A vertical groove is formed on each of the inner walls of both sides of the fixed frame. Both ends of the movable block are slidably connected to the vertical grooves. A mounting base is fixed to the side of the movable block. A mounting groove is formed on the inner side of each end of the mounting base. A support rod is rotatably connected to the mounting groove. A groove is formed at the end of the support rod. A fixed rod is connected to the groove through a connecting mechanism. A roller is fixed between the two ends of the support rod.

[0007] Furthermore, a rotating block is fixedly connected to each side of the support rod, and a rotating groove is opened on each side of the inner wall of the mounting groove, with the end of the rotating block rotatably connected in the rotating groove.

[0008] Furthermore, the connecting mechanism includes a movable groove formed in the inner wall of the groove, a pressing plate and a moving plate slidably connected in the movable groove, a sliding hole obliquely formed in the moving plate, a second spring connected between the moving plate and the inner wall of the movable groove, a snap-fit ​​plate fixed at the end of the moving plate away from the second spring, a snap-fit ​​groove formed at the end of the fixing rod, and the end of the snap-fit ​​plate penetrating into the groove and inserted into the snap-fit ​​groove.

[0009] Furthermore, the connecting mechanism also includes a movable groove formed at the end of the extrusion plate, the movable plate being located inside the movable groove, a slide rod being fixed inside the movable groove, the slide rod being slidably connected inside the sliding hole, and a spring connecting the extrusion plate and the inner wall of the movable groove.

[0010] Furthermore, a push rod is fixed to the side of the extrusion plate, and a fixed plate is hinged to the end of the push rod. The fixed plate has an elliptical structure. The top of the mounting base has a through hole that communicates with the mounting groove and the movable groove. Two sets of fixing holes are respectively opened on the inner walls of the two sides of the through hole. The fixed plate is rotatably connected in the fixing holes.

[0011] Furthermore, the extrusion plate is provided with a longitudinal slider, and the movable groove is provided with a longitudinal sliding groove that cooperates with the longitudinal slider. The moving plate is provided with a transverse slider, and the movable groove is provided with a transverse sliding groove that cooperates with the transverse slider.

[0012] The beneficial effects of this utility model are:

[0013] When in use, the motor is started, and the output end of the motor drives the lead screw to rotate. Under the limit of the vertical groove, the rotation of the lead screw drives the moving block to move vertically, which in turn drives the roller located on the moving block to move.

[0014] By setting up the moving block and the vertical groove, the two ends of the moving block are slidably connected in the vertical grooves on both sides, which can limit the movement of the moving block and prevent the moving block from rotating with the rotation of the lead screw.

[0015] By using the connecting mechanism, when replacing the roller, the connecting mechanism can first disconnect the connection between the support rod and the roller inside the mounting base. Then, after replacing it with a brand new roller, the connecting mechanism can be activated again to connect and fix the fixing rod and the support rod. This allows the roller to be replaced quickly when needed.

[0016] With the setting of fixed plate, through hole and fixing hole, fixed plate and top of push rod are hinged. When fixed plate is rotated 90 degrees, fixed plate can be rotated into through hole or into fixing hole on both sides of through hole, thereby fixing the position of push rod and fixed plate.

[0017] By setting longitudinal sliders and longitudinal chutes, the stability of the extrusion plate movement can be improved; by setting transverse sliders and transverse chutes, the stability of the moving plate movement can be improved. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution for a smoothing device for architectural decorative paper, including a fixed frame 1. A motor 2 is fixed to the inner bottom of the fixed frame 1. The output end of the motor 2 is connected to one end of a lead screw 3. The other end of the lead screw 3 is rotatably connected to the inner top of the fixed frame 1. A movable block 4 is threaded onto the lead screw 3. A vertical groove 5 is provided on each of the inner walls of both sides of the fixed frame 1. The two ends of the movable block 4 are slidably connected to the vertical grooves 5. A mounting base 6 is fixed to the side of the movable block 4. A mounting groove 7 is provided on the inner side of each end of the mounting base 6. A support rod 8 is connected to the movable connection. A groove 11 is provided at the end of the support rod 8. A fixed rod 12 is connected to the groove 11 through a connecting mechanism. A roller 13 is fixed between the two ends of the support rod 8. A rotating block 9 is fixedly connected to each side of the support rod 8. A rotating groove 10 is provided on each side of the inner wall of the mounting groove 7. The end of the rotating block 9 is rotatably connected to the rotating groove 10. When in use, the motor 2 is started. The output end of the motor 2 drives the lead screw 3 to rotate. Under the limit of the vertical groove 5, the rotation of the lead screw 3 drives the moving block 4 to move vertically, which in turn drives the roller 13 located on the moving block 4 to move.

[0028] See Figure 3 , Figure 4 and Figure 5 and Figure 6The connecting mechanism includes a movable groove 14 formed in the inner wall of the groove 11. A pressing plate 15 and a moving plate 19 are slidably connected within the movable groove 14. A sliding hole 20 is obliquely formed on the moving plate 19. A second spring 22 connects the moving plate 19 and the inner wall of the movable groove 14. A snap-fit ​​plate 21 is fixed to the end of the moving plate 19 away from the second spring 22. A snap-fit ​​groove 23 is formed at the end of the fixing rod 12. The end of the snap-fit ​​plate 21 penetrates into the groove 11 and inserts into the snap-fit ​​groove 23. The connecting mechanism also includes a movable groove 16 formed at the end of the pressing plate 15. 19 is located inside the movable groove 16, and a slide rod 17 is fixed inside the movable groove 16. The slide rod 17 is slidably connected inside the sliding hole 20. A spring 24 is connected between the extrusion plate 15 and the inner wall of the movable groove 14. Through the setting of the connecting mechanism, when the roller 13 is replaced, the connecting mechanism can first disconnect the connection between the support rod 8 in the mounting base 6 and the roller 13. Then, after replacing with a brand new roller 13, the connecting mechanism can be activated again to connect and fix the fixed rod 12 and the support rod 8. Thus, when the roller 13 needs to be replaced, it can be replaced quickly.

[0029] See Figure 2 A push rod 18 is fixed to the side of the extrusion plate 15. The end of the push rod 18 is hinged to a fixed plate 25. The fixed plate 25 has an elliptical structure. The top of the mounting base 6 has a through hole 26 that communicates with the mounting groove 7 and the movable groove 14. Two sets of fixing holes 27 are respectively opened on the inner walls of the two sides of the through hole 26. The fixed plate 25 is rotatably connected in the fixing holes 27. Through the arrangement of the fixed plate 25, the through hole 26 and the fixing holes 27, the fixed plate 25 is hinged to the top of the push rod 18. When the fixed plate 25 is rotated ninety degrees, the fixed plate 25 can be rotated into the through hole 26 or into the fixing holes 27 on the inner walls of the two sides of the through hole 26, thereby fixing the position of the push rod 18 and the fixed plate 25.

[0030] See Figure 3 The extrusion plate 15 is provided with a longitudinal slider, and the movable groove 14 is provided with a longitudinal groove that cooperates with the longitudinal slider. The moving plate 19 is provided with a transverse slider, and the movable groove 14 is provided with a transverse groove that cooperates with the transverse slider. By setting the longitudinal slider and the longitudinal groove, the stability of the movement of the extrusion plate 15 can be improved. By setting the transverse slider and the transverse groove, the stability of the movement of the moving plate 19 can be improved.

[0031] When in use, after attaching the decorative paper to the wall, move the bottom of the fixed frame 1 to a position close to the wall and make the roller 13 contact the decorative paper on the wall. Then start the motor 2. The output end of the motor 2 drives the lead screw 3 to rotate. Under the limit of the vertical groove 5, the rotation of the lead screw 3 drives the moving block 4 and the mounting base 6 to move vertically, thereby driving the roller 13 to move vertically, so as to smooth the decorative paper.

[0032] When the roller 13 needs to be replaced, rotate the fixed plate 25 ninety degrees. The fixed plate 25 rotates inside the fixed hole 27 until the long half-axis of the fixed plate 25 is located in the through hole 26. Then, move the fixed plate 25 away from the lead screw 3. The fixed plate 25 drives the push rod 18 to move, and the push rod 18 drives the extrusion plate 15 to move. At this time, the extrusion plate 15 stretches the spring 24. The extrusion plate 15 drives the slide rod 17 to move. During the movement, the slide rod 17 will extrude the sliding hole 20, thereby driving the sliding hole 20 and the moving plate 19 to move outward from the mounting base 6. The movement of the moving plate 19 drives the locking mechanism. When the connecting plate 21 leaves the snap-fit ​​groove 23 at the end of the fixing rod 12, the fixing plate 25 is located between the two fixing holes 27 away from the lead screw 3. Then, the fixing plate 25 is rotated ninety degrees, and the end of the long half shaft of the fixing plate 25 rotates into the fixing holes 27 on both sides to fix the position of the fixing plate 25 and the push rod 18. According to the above operation, the push rod 18 at the other end of the mounting base 6 is moved to release its connection to the fixing rod 12 at the other end of the roller 13. Then, the roller 13 and the fixing rod 12 are moved to the end away from the lead screw 3, which drives the fixing rod 12 to leave the groove 11 and remove the roller 13.

[0033] Next, take out a brand new roller 13 and move it laterally into the mounting base 6 so that the fixing rods 12 at both ends are located in the grooves 11 at both ends. Then, rotate the fixing plate 25 ninety degrees again so that the long half-shaft of the fixing plate 25 is located in the through hole 26. Then, under the action of spring 1 24, the pressing plate 15 is driven to reset and move. Under the action of spring 22, the moving plate 19 is driven to reset and move, thereby driving the snap-fit ​​plate 21 to move closer to the fixing rod 12 until the snap-fit ​​plate 21 is inserted into the snap-fit ​​groove 23 at the end of the fixing rod 12, fixing the position of the fixing rod 12. Then, the fixing plate 25 can be rotated again so that the long half-shaft of the fixing plate 25 rotates into the fixing hole 27 near the end of the lead screw 3, thus completing the connection between the fixing rod 12 and the support rod 8, thereby completing the replacement and installation of the roller 13.

[0034] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
