Description

Technical Field

[0001] This utility model relates to the field of wood door processing technology, and in particular to an automatic limiting device for wood door surface painting. Background Technology

[0002] Wooden doors, or doors made of wood, can be categorized into many types based on their material, craftsmanship, and purpose, and are widely used in residential, commercial, and commercial buildings. Styles include European retro, minimalist modern, American, Mediterranean, Chinese, French romantic, and Italian. During the manufacturing process, the surface of wooden doors undergoes a painting process, which not only extends their lifespan but also enhances their aesthetic appeal.

[0003] However, existing technologies still have shortcomings. The existing wood door painting process lacks professional fixing devices, which makes the wood door prone to movement during the painting process. This movement of the wood door causes the paint to not be sprayed evenly, resulting in an uneven paint surface that seriously affects the appearance and quality of the wood door and increases the defect rate of wood door manufacturing.

[0004] Therefore, we propose an automatic limit device for the painting process on wooden door surfaces to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an automatic limiting device for the surface painting of wooden doors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic limiting device for painting the surface of wooden doors includes a base; a support column is fixedly connected to the upper surface of the base; a first electric actuator is fixedly connected to the upper surface of the support column; a mounting plate is fixedly connected to the upper end of the first electric actuator; a base plate is fixedly connected to the outer surface of the mounting plate; a through hole is provided on the upper surface of the base plate; a mounting bracket is fixedly connected to the upper surface of the mounting plate; a second electric actuator is fixedly connected to the inner surface of the mounting bracket; a limiting plate is fixedly connected to one end of the second electric actuator; a third electric actuator is fixedly connected to one side of the upper surface of the base; a first mounting block is fixedly connected to the upper end of the third electric actuator; a connecting hole is provided on the outer surface of the first mounting block; a motor is fixedly connected to one side of the outer surface of the first mounting block; a connecting rod is slidably installed on the inner surface of the connecting hole; a second mounting block is fixedly connected to one end of the connecting rod; a fourth electric actuator is fixedly connected to one side of the outer surface of the second mounting block; and a fixing plate is fixedly connected to one end of the fourth electric actuator.

[0007] Preferably, the limiting plate is slidably mounted on the upper surface of the base plate; the output end of the motor is fixedly connected to one end of the connecting rod.

[0008] Preferably, the base is an annular plate; the second mounting block is rotatably mounted on the outer surface of the first mounting block.

[0009] Preferably, a protective pad is fixedly connected to one outer surface of the limiting plate; and an anti-slip plate is fixedly connected to one outer surface of the fixing plate.

[0010] Preferably, the support column is located on the left and right sides of the upper surface of the base; the third electric actuator is located on the front and rear sides of the upper surface of the base.

[0011] In this utility model, an automatic limiting device for painting the surface of a wooden door is described. This device comprises a base, support column, a first electric actuator, mounting plate, bottom plate, mounting bracket, second electric actuator, limiting plate, third electric actuator, first mounting block, motor, connecting hole, connecting rod, second mounting block, fourth electric actuator, fixing plate, and through hole. Activating the third electric actuator moves the first mounting block, causing the fixing plate to move away from the bottom plate. The wooden door is then pushed onto the upper surface of the bottom plate. Activating the second electric actuator moves the limiting plate, which in turn moves the wooden door to the center of the bottom plate. Activating the second electric actuator again limits the movement. The board is removed from the wooden door. Then, the No. 3 electric actuator is activated, moving the No. 1 mounting block above the base plate. Next, the No. 4 electric actuator is activated, which moves the No. 2 mounting block, fixing the wooden door in place. Then, the No. 1 and No. 3 electric actuators are activated. The No. 1 electric actuator moves the base plate downwards, and the No. 3 electric actuator moves the wooden door upwards. Then, the motor is activated, which rotates the connecting rod. The rotation of the connecting rod rotates the No. 2 mounting block, which in turn rotates the wooden door. This facilitates the painting process on the wooden door, enabling rapid positioning of the wooden door and making double-sided painting easier, thus improving efficiency. In this utility model, an automatic limiting device for painting the surface of a wooden door is provided. The protective pad prevents the limiting plate from damaging the wooden door during positioning, and the anti-slip plate improves the stability of fixing the wooden door. This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description

[0016] Furthermore, the limiting plate 8 is slidably mounted on the upper surface of the base plate 5; the output end of the motor 12 is fixedly connected to one end of the connecting rod 14.

[0017] Furthermore, the base 1 is an annular plate; the second mounting block 15 is rotatably mounted on the outer surface of the first mounting block 11.

[0018] Furthermore, a protective pad 9 is fixedly connected to one outer surface of the limiting plate 8; and an anti-slip plate 18 is fixedly connected to one outer surface of the fixing plate 17.

[0019] Furthermore, the support column 2 is located on the left and right sides of the upper surface of the base 1; the third electric actuator 10 is located on the front and rear sides of the upper surface of the base 1.

[0020] In this utility model, during use, activating the third electric actuator 10 will move the first mounting block 11, causing the fixing plate 17 to move away from the base plate 5.

Activating the third electric actuator 10 will move the first mounting block 11 above the base plate 5. Activating the fourth electric actuator 16 will move the second mounting block 15. The movement of the device will fix the wooden door. Then, the first electric actuator 3 and the third electric actuator 10 will be activated. The first electric actuator 3 will drive the base plate 5 to move downward, and the third electric actuator 10 will drive the wooden door to move upward. Then, the motor 12 will be activated. The motor 12 will drive the connecting rod 14 to rotate. The rotation of the connecting rod 14 will drive the second mounting block 15 to rotate. The rotation of the second mounting block 15 will drive the wooden door to rotate, which will facilitate the painting process of the wooden door. This achieves quick positioning of the wooden door and makes it easier to paint both sides of the wooden door, thus improving efficiency. The protective pad 9 can prevent the limiting plate 8 from damaging the wooden door when positioning it, and the anti-slip plate 18 can improve the stability of fixing the wooden door.
