Description

Technical Field

[0001] This utility model relates to the field of door panel processing technology, and in particular to a door panel flipping and falling anti-collision mechanism. Background Technology

[0002] Door panels, a structural component of buildings, primarily function to enclose the interior. With the evolving needs of society, the economy, and home decoration, the processing requirements for door panels are becoming increasingly stringent, including techniques such as carving, painting, and lamination.

[0003] Before carving, painting, and laminating door panels, they need to be sanded. Existing sanding equipment first sands one side of the door panel smooth, and then feeds it onto a conveyor belt with a flipping mechanism to turn the door panel over, making it easier to sand the other side. Existing flipping equipment usually has two clamping arms installed on a conveyor roller bed. Two clamping plates are set inside the clamping arms. The door panel is fed into the two clamping arms by the conveyor roller bed, and the clamping plates are clamped by a cylinder. The door panel is then held in the clamping arms, and the clamping arms flip 180 degrees to complete the flipping operation. However, when the cylinder drives the clamping plates, the air pressure in the cylinder is often unstable due to various factors, causing the clamped door panel to slip. Although the flipping operation can be completed, when the door panel slides between the two clamping blocks, the side of the door panel is prone to hitting the clamping arms, resulting in scratches or damage to the side of the door panel. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model provides a door panel flipping and falling anti-collision mechanism to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a door panel flipping and falling anti-collision mechanism, including a conveyor bed, a flipping arm, and a protective mechanism. The conveyor bed is equipped with conveyor rollers. Two flipping arms are symmetrically arranged in the conveyor bed and rotate 180 degrees within it. Each flipping arm has a clamping cavity, and two clamping plates are symmetrically arranged vertically within the clamping cavity, moving towards each other within the cavity. Two protective mechanisms are symmetrically arranged in the two flipping arms and located at the bottom end of the flipping arm when it is in the vertical position. Each protective mechanism consists of a first telescopic cylinder and a protective plate. Two first telescopic cylinders are symmetrically arranged on the outer side of the flipping arm and located on both sides of the clamping cavity. The two ends of the protective plate are fixedly connected to the telescopic ends of the two first telescopic cylinders, respectively.

[0006] Preferably, the top horizontal plane of the conveying roller is level with the top of the lower clamping plate inside the clamping cavity of the flipping arm.

[0007] Preferably, a second telescopic cylinder is installed at the top and bottom of the flipping arm to drive the clamping plate to move. A rubber clamping pad is installed in the clamping surface of the clamping plate, and the surface of the clamping pad is provided with anti-slip texture. The clamping pad abuts against the lower side of the door panel.

[0008] Preferably, a rubber buffer pad is installed on the side of the protective plate facing the first telescopic cylinder, and the surface of the rubber buffer pad is in contact with the side of the door panel.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] With the protective mechanism in place, after the clamping plate holds the door panel, the first telescopic cylinder drives the protective plate to move to the side of the door panel, thereby creating a counterforce on the side of the door panel. When the door panel is rotated to a 90-degree vertical position, the protective plate provides support to the door panel, thus preventing the door panel from slipping due to unstable air pressure or loosening of the clamping plate. This also avoids the side of the door panel hitting the rotating arm, which could cause wear or damage to the door panel and improve the quality of subsequent processed products.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 In this embodiment, a door panel flipping and falling anti-collision mechanism includes a conveyor bed 1, a flipping arm 2, and a protective mechanism 3. The conveyor bed 1 is provided with a conveyor roller 11. The flipping arm 2 consists of two symmetrically arranged in the conveyor bed 1, which flip 180 degrees in the conveyor bed 1. The flipping arm 2 is provided with a clamping cavity 21. The clamping cavity 21 is provided with two clamping plates 22 arranged vertically and vertically, and the two clamping plates 22 move towards each other in the clamping cavity 21. The protective mechanism 3 consists of two symmetrically arranged in the two flipping arms 2, and is located at the bottom end of the flipping arm 2 when it is in the vertical state. The protective mechanism 3 is composed of a first telescopic cylinder 31 and a protective plate 32. The first telescopic cylinder 31 consists of two symmetrically arranged in the outer surface of the flipping arm 2, and is located on both sides of the clamping cavity 21. The two ends of the protective plate 32 are fixedly connected to the telescopic ends of the two first telescopic cylinders 31, respectively.

[0018] With the above technical solution, the door panel moves along the conveyor roller 11 on the conveyor bed 1 during use. When the door panel moves into the clamping cavity 21 of the two flipping arms 2, the door panel is clamped in the flipping arms 2 by the two clamping plates 22 moving towards each other. At this time, the first telescopic cylinder 31 drives the protective plate 32 to move, so that the protective plate 32 abuts against the side of the door panel. Then the flipping arm 2 flips 180 degrees, thereby completing the flipping of the door panel. During the flipping process, if the air pressure is unstable, the clamping plates 22 may not be able to hold the sides of the door panel steadily, and the door panel may slip. This application uses the protective plate 32 to abut against the side of the door panel. When the air pressure is unstable, the door panel is supported because it is abutting against the protective plate 32 of the two protective mechanisms 3, thus preventing slipping and collision, thereby effectively avoiding damage to the door panel and improving the quality of the product.

[0019] Preferably, the top horizontal plane of the conveying roller 11 is level with the top of the lower clamping plate 22 inside the clamping cavity 21 of the flipping arm 2.

[0020] The above technical solution ensures that the door panel is conveyed to the lower clamping plate 22, so that the two clamping plates 22 can stably clamp the door panel.

[0021] Preferably, a second telescopic cylinder 23 is installed at the top and bottom of the flipping arm 2 to drive the clamping plate 22 to move. A rubber clamping pad 24 is installed in the clamping surface of the clamping plate 22, and the surface of the clamping pad 24 is provided with anti-slip texture. The clamping pad 24 abuts against the lower side of the door panel.

[0022] Through the above technical solution, the second telescopic cylinder 23 is used to drive the clamping plate 22 to move stably, the rubber clamping pad 24 is used to buffer the clamping force of the clamping plate 22 to avoid damage to the door panel due to excessive pressure, and the anti-slip texture on the surface of the clamping pad 24 is used to increase the friction between the clamping pad 24 and the surface of the door panel to improve the stability of clamping.

[0023] Preferably, a rubber buffer pad 33 is installed on the side of the protective plate 32 facing the first telescopic cylinder 31, and the surface of the rubber buffer pad 33 is in contact with the side of the door panel.

[0024] Through the above technical solution, since rubber is elastic, the surface of the rubber buffer pad 33 is in contact with the door panel, preventing the door panel after being clamped from moving when the protective plate 32 moves, thereby avoiding damage to the door panel. At the same time, when the door panel slides down, it plays a buffering role to prevent direct collision with the protective plate 32, thereby effectively improving the product quality of the door panel in subsequent processing.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
