Description

Technical Field

[0001] This utility model relates to the field of furniture production technology, and in particular to a rapid painting device for wooden door production. Background Technology

[0002] Furniture refers to a broad category of appliances and facilities essential for human beings to maintain normal life, engage in production practices, and carry out social activities. Solid wood furniture refers to furniture made of natural wood. During the production process, solid wood furniture is generally coated with clear varnish or matte varnish to showcase the natural color of the wood. In the varnishing process, the surface of the furniture is often painted by dipping a brush in the varnish. However, the existing wooden-handled brushes cannot be extended in length, and workers need to stand on A-frame ladders to paint in higher areas. Furthermore, wooden-handled brushes are disposable; when the bristles are no longer usable, the entire wooden-handled brush is thrown away, resulting in a waste of resources.

[0003] Chinese utility model patent (authorization announcement number: CN211065425U) Name: A Wood Handle Painting Device The device includes a brush head, a brush handle, and brush bristles. The brush head has a brush handle at its right end, with a threaded hole at the right end of the handle. An extension rod is installed at the right end of the handle, and the extension rod is connected to the brush handle with an external threaded head, which is threaded into the threaded hole. The left end of the brush head has a connector, and a fixing sleeve is fitted on the outside of the connector. In use, the extension rod is connected to the threaded hole through the external threaded head. The extension rod increases the length of the painting device, making it easier for workers to use. The connector is inserted into the mounting groove, and the connector is fixed to the brush head with fixing bolts. A partition is glued to the right end of the connector, and the fixing sleeve is fitted onto the left end of the connector. Brush bristles with glue applied to one end are inserted into the fixing sleeve, and the brush bristles are fixed to the fixing sleeve and connector with glue. Finally, the fixing sleeve is fixed to the connector with rivets, thus completing the installation of the wood handle painting device. However, it requires manual painting, which is not only labor-intensive but also inefficient. Utility Model Content

[0024] like Figure 1 and 3 As shown, a rapid painting device for wooden door production includes a base 1 and a stepper motor (not shown). Both the base 1 and the stepper motor are fixed to the ground. A column 2 is fixed to the center of the base 1. A bearing A is installed on the upper section of the column 2. A crossbar 3 and a connecting plate 4 are fixed radially on the bearing A. The crossbar 3 intersects with the connecting plate 4. A slider 5 is slidably mounted on the crossbar 3. A brush 6 is detachably mounted on the slider 5. A guide wheel 7 is rotatably mounted on the top of the column 2. A steel wire rope 8 is wound around the guide wheel 7. The slider 5 is connected to the shaft of the stepper motor via the steel wire rope 8. A support platform 9 is fixed to the middle section of the column 2. A reduction motor 10 is fixed on the support platform 9. An opening is made on the connecting plate 4 along its extending direction. An elongated through-hole 11 is provided, and an L-shaped rod 12 is slidably installed inside the elongated through-hole 11. The rod 12 is detachably installed on the shaft of the geared motor 10. The L-shaped rod 12, installed on the geared motor 10, acts as an eccentric wheel. When it slides inside the elongated through-hole 11, it drives the crossbar 3 to swing left and right, thereby causing the brush 6 to paint the wooden door. At the same time, the stepper motor can pull the brush 6 to the unpainted area to continue painting (the wooden door is placed under the brush 6 via a workbench, and sensors are set on both sides of the wooden door. When the sensors detect the crossbar 3, the stepper motor steps once, causing the brush 6 to move outside the wooden door to avoid affecting the painting quality). This avoids manual painting and improves labor efficiency.

[0025] In this embodiment, as Figure 1As shown, a B bearing is installed on the lower section of column 2, and a diagonal brace 13 is fixed on the B bearing. The diagonal brace 13 is used for the linkage between the crossbar 3 and the B bearing, which enhances the stability of the crossbar 3 and reduces the risk of the crossbar 3 bending.

[0026] In this embodiment, as Figure 1 and 2 As shown, the base 1 is fixed to the ground by expansion screws, and the expansion bolt 14 is fixed in the mounting hole in the ground. The expansion screw includes a bolt 14, an expansion tube 15, and a conical nut 16. The expansion tube 15 is fitted onto the bolt 14 and has a slit at its tail. The conical nut 16 is screwed onto the bolt 14 to open the tail of the expansion tube 15. The outer peripheral wall of the conical nut 16 is provided with a rib 17. By setting the conical nut 16 to be threadedly connected to the bolt 14, and the rib 17 on the outer peripheral wall of the conical nut 16, the conical nut 16 can only move along the bolt 14 towards the end of the bolt 14 when the bolt 14 rotates. The conical nut 16 cannot rotate. When the conical nut 16 moves to the tail of the expansion tube 15, the tail of the expansion tube 15 is opened from the slit by the conical nut 16 and tightly fits into the inside of the mounting hole. The conical nut 16 and the expansion tube 15 are locked together, thereby fixing the bolt 14. When the load is unstable and the bolt 14 loosens, the rib 17 on the outer peripheral wall of the tapered nut 16 can be locked with the inner wall of the mounting hole for the expansion bolt, thereby ensuring the fastening stability of the bolt 14.

[0027] In this embodiment, as Figure 1 and 4 As shown, the crossbar 3 is a cylinder, and a groove 18 is provided on the crossbar 3 along its extension direction. The slider 5 is U-shaped, and a limit block 19 is fixed on the inner wall of the slider 5. The limit block 19 is slidably installed in the groove 18. A spring 20 is sleeved on the crossbar 3. The spring 20 is compressed and installed on the diagonal support rod 13 through the slider 5. When the stepper motor rotates forward to paint the entire wooden door, the unpainted wooden door is removed and placed. Then the stepper motor is reversed, and the slider 5 gradually returns to its original position under the action of the spring 20, thereby painting the new door. There is no need to manually reset the slider 5 for painting. The structure is simple and the operation is convenient.

[0028] In this embodiment, as Figure 2 As shown, the end of the rib 17 facing away from the head of the bolt 14 is provided with a guide slope, which can facilitate the tapered nut 16 to slide into the mounting hole along the axis of the mounting hole, thereby realizing the pre-embedding of the tapered nut 16.

[0029] In this embodiment, as Figure 2As shown, a weakening groove 21 is provided on the wall of the expansion tube 15, and the warp extends into the weakening groove 21. The weakening groove 21 is a structure provided on the tube wall to weaken the strength of the tube wall. The expansion tube 15 has low strength at the weakening groove 21 and is prone to deformation. The tapered nut 16 can easily open the tail of the expansion tube 15 and then clamp it with the inner wall of the mounting hole to achieve a fastening effect.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
